Through systematic research on the PbO/PbF2/H3BO3 ternary phase diagram, two new lead(ii) borates, β-Pb6B10O21 and Pb4B8O16, were synthesized by a high temperature solution method. The polymerization degree of the B-O network was analyzed with increasing B : Pb ratio.

###### IUCr) Structure determination and phase transition behaviour of di-methyl sulfate

However, above 50 K the thermal expansivity of the cell volume for the heating sequence is markedly lower when compared with the cooling sequence. Similar behaviour is shown by the a, c and b lattice constants, whereas the b lattice constant exhibits a less negative expansion. The thermal treatment of the sample offers a likely explanation for this observation. The sample was initially quenched at 100 K and then cooled to 5 K. Data recorded on warming this sample were composed entirely of the phase II structure until the transition onset around 210 K. In contrast, the phase II sample for the cooling sequence was transformed via the phase I structure and lattice parameters for both phases could be refined down to 167 K. Very weak peaks corresponding to the phase I structure were in fact observed down to 100 K. The intergrowth of phase II and phase I structures and sluggish nature of the transition would both affect the observed thermal expansivity of phase II in the cooling sequence. ...

###### Compartmentalization of biomolecules and reactions by liquid-liquid phase coexistence | JILA Science

Liquid-liquid phase separation is common in aqueous macromolecule solutions, leading to formation of droplets that are greatly enriched in macromolecules. This presentation will describe studies of liquid-liquid phase separation in relatively simple polymer solutions, both as models for membraneless organelles in eukaryotic cells and as potential prebiotic compartments (membraneless protocells). Solutes such as ions, small molecules, and biopolymers can become compartmentalized by partitioning due to the different solvent environment and/or affinity interactions (e.g. ion pairing, hydrogen bonding). We are studying mechanisms for, and consequences of, this type of compartmentalization using a variety of simple model systems composed of phase-separating aqueous polymer solutions. Through these types of studies, we hope to uncover underlying physiochemical mechanisms in cellular organization and to identify new avenues for biomimetic systems for applications in biotechnology and materials science. ...

###### Dehydration entropy drives liquid-liquid phase separation by molecular crowding | Communications Chemistry

Complex coacervation driven liquid-liquid phase separation (LLPS) of biopolymers has been attracting attention as a novel phase in living cells. Studies of LLPS in this context are typically of proteins harboring chemical and structural complexity, leaving unclear which properties are fundamental to complex coacervation versus protein-specific. This study focuses on the role of polyethylene glycol (PEG)-a widely used molecular crowder-in LLPS. Significantly, entropy-driven LLPS is recapitulated with charged polymers lacking hydrophobicity and sequence complexity, and its propensity dramatically enhanced by PEG. Experimental and field-theoretic simulation results are consistent with PEG driving LLPS by dehydration of polymers, and show that PEG exerts its effect without partitioning into the dense coacervate phase. It is then up to biology to impose additional variations of functional significance to the LLPS of biological systems. Liquid-liquid phase separation occurs in cells and can be induced in

###### Protein Liquid-Liquid Phase Transitions: The Science Is About to Gel | ALZFORUM

Though liquid-liquid phase separation is an emerging field, scientists in Leuven were already optimistic that it could lead to new strategies to tackle disease. I absolutely believe that this field is ripe for new therapies, said Taylor. He noted that companies have made substantial investments in this regard and that he fields constant inquiries from venture capitalists about manipulating phase transitions as a means to modulate disease. As a proof of principle, Lindsay Becker, who works at Aaron Gitlers lab at Stanford University, outlined how knocking down ataxin-2 expression improved symptoms in a mouse model of ALS. Becker and colleagues had previously found that the RNA-binding protein Pbp1, a yeast homolog of ataxin-2, makes TDP43 more toxic. Given that ataxin-2 mutations increase the risk for motor neuron disease, the researchers suspected that ataxin-2 did the same to TDP43 in neurons. Becker recently reported in Nature that crossing TDP43-overexpressing mice with Ataxin-2-negative ...

###### talks.cam : Cellular Organization Through Liquid-Liquid Phase Separation

If you have a question about this talk, please contact Akhila Kadgathur Jayaram.. Biomolecular condensates are two- and three-dimensional compartments in eukaryotic cells that concentrate specific collections of proteins and nucleic acids without an encapsulating membrane. Many condensates behave as dynamic liquids, and are believed to form through liquid-liquid phase separation (LLPS) driven by interactions between multivalent constituents. While we understand much about the physical mechanisms that promote and regulate LLPS , we know less about the biochemical functions that arise from this process, and many roles of LLPS in biology remain to be discovered. In my talk I will explain how my lab began our work on biological LLPS , and then discuss how assembly of two distinct signaling cascades into condensates causes modulation of their biochemical activities. Finally, I will discuss a new direction in the lab focused on understanding how chromatin may be organized by LLPS , and dynamically ...

**phase transition**in TlH2PO4. AU - Kim, Kum Bae. AU - Lee, Kwang Sei. AU - Lee, Cheol Eui. PY - 1998/6. Y1 - 1998/6. N2 - The low-temperature II-III**phase transition**of TlH2PO4 (ferroelastic in phase II) at 230 K (Tc2) was studied by a polarizing microscope between 300 and 80 K. Despite the II-III**phase transition**at Tc2, the two kinds of ferroelastic domain structures with the (100) and/or (001) and (201) domain boundaries were still observed below Tc2 and were nearly temperature-independent. No new domain structures corresponding to antiferroelectric or ferrielectric orientation states were observed in phase III. The possible intermediate structural**phase transition**near 130 K suggested by vibrational spectroscopic study [B. Pasquier et al.: Chem. Phys. 171 (1993) 203] was not detected. The transition at Tc2 without optically detectable new domains indicates that the monoclinic crystal system of the phase II persists in phase ...###### Critical behavior within 20 fs drives the out-of-equilibrium laser-induced magnetic phase transition in nickel | Science...

It has long been known that ferromagnets undergo a

**phase transition**from ferromagnetic to paramagnetic at the Curie temperature, associated with critical phenomena such as a divergence in the heat capacity. A ferromagnet can also be transiently demagnetized by heating it with an ultrafast laser pulse. However, to date, the connection between out-of-equilibrium and equilibrium phase transitions, or how fast the out-of-equilibrium phase transitions can proceed, was not known. By combining time- and angle-resolved photoemission with time-resolved transverse magneto-optical Kerr spectroscopies, we show that the same critical behavior also governs the ultrafast magnetic**phase transition**in nickel. This is evidenced by several observations. First, we observe a divergence of the transient heat capacity of the electron spin system preceding material demagnetization. Second, when the electron temperature is transiently driven above the Curie temperature, we observe an extremely rapid change in the ...###### Epitaxy surface effect on the first-order phase transition properties in a ferroelectric thin film

摘要 By modifying the interchange interactions and the transverse fields on the epitaxy surface layer, this paper studies the

**phase transition**properties of an n-layer ferroelectric thin film by the Fermi-type Greens function technique based on the transverse Ising model with a four-spin interaction. The special attention is given to the effect of the epitaxy surface layer on the first-order**phase transition**properties in the parameter space constructed by the ratios of the bulk transverse field and the bulk four-spin interaction to the bulk two-spin interaction with the framework of the higher-order decoupling approximation to the Fermi-type Greens function. The results show that the first-order**phase transition**properties will be changed significantly due to the modification of interchange interaction and transverse field parameters on the epitaxy surface layer. The dependence of the first-order**phase transition**properties on the thickness of ferroelectric thin films is also discussed ...###### Biochemical and Biophysical Systems Group

Most drug-target proteins reside in cell membranes. Drug responses can be affected by the local environment - which lipids are present, and whether they self-segregate into rafts - a controversial topic due to difficulties in observing or simulating these phenomena. Our simulations for the first time accurately reproduce complex biological membrane phase separations. These simulations require longer timescales than typical atomistic simulations, and greater accuracy than existing coarse-grained methods. We refine coarse-grained parameters using atomistic results. The right-most image shows the phase diagram - calculated from our new simulations - of membranes composed of varying-percentage mixtures of three lipids, colored according to the key on the left. Combinations of colors show which phases are present. Our method will be useful in drug development - for example, in silico screening candidate molecules for adverse side effects.

###### Kinetics of phase transitions in passive and active matters

University of Minnesota. A

**phase transition**is an abrupt change between different structures of passive or active constitutes, with snow formation, graphite-diamond transition and emergence of bird flocking as common examples. The kinetics of a**phase transition**is essential to understand its microscopic mechanism and to control the transition rate, intermediate state and the final structure morphology. However, it is challenging to predict the kinetics pathway duo to complex interaction and the many-body nature of these processes. Here I study the kinetics of phase transitions in a passive system, crystal-crystal transitions in colloids, and in an active system, swarming transition in E. coli suspensions. In the colloidal crystal-crystal transitions, we employed diameter-tunable microgel spheres to trigger a transition from square lattice to triangular lattice. Under static condition, video microscopy directly demonstrated a two-step nucleation process with an intermediate liquid state. This ...###### Oiling out or molten hydrate-liquid-liquid phase separation in the system vanillin-water

Vanillin crystals in a saturated aqueous solution disappear and a second liquid phase emerges when the temperature is raised above 51 degrees C. The phenomenon has been investigated with crystallization and equilibration experiments, using DSC, TGA, XRD and hot-stage microscopy for analysis. The new liquid solidifies on cooling, appears to melt at 51 degrees C, and has a composition corresponding to a dihydrate. However, no solid hydrate can be detected by XRD, and it is shown that the true explanation is that a liquid-liquid phase separation occurs above 51 degrees C where the vanillin-rich phase has a composition close to a dihydrate. To our knowledge, liquid-liquid phase separation has not previously been reported for the system vanillin-water, even though thousands of tonnes of vanillin are produced globally every year.. ...

Dynamical fluctuations in globally conserved quantities such as baryon number, strangeness, charge, and isospin are suggested to carry information about the de-confinement and chiral phase transitions. An observation of enhanced dynamical fluctuations or non-monotonic behavior of transverse momentum correlations as a function of colliding energy might indicate the system has probed the predicted QCD critical point. The STAR experiment has performed a comprehensive study of the energy and charge dependence of dynamical particle ratio ($K/\pi$, $p/\pi$, and $K/p$) fluctuations, net-charge fluctuations, and transverse momentum correlations in the STAR TPC at mid-rapidity, as well as neutral-charge pion fluctuations at forward rapidity. The charge dependence of particle ratio fluctuations exhibit differences between same and opposite sign dynamical particle ratio fluctuations compared to inclusive charged dynamical fluctuations. Neutral-charge pion fluctuations at forward rapidity are measured by ...

###### Entropy Formulation of Evolutionary Phase Transitions

This group existed from 2013 to 2016. It was led by Elisabetta Rocca.. The main research goal was to establish new methods with a novel mathematical formulation of physical problems. The researchers aimed to obtain relevant mathematical results in order to gain further insight into new models for phase transitions and the corresponding evolution PDE systems. The new approach was particularly helpful within the investigation of issues like existence, uniqueness, control, and long-term behavior of the solutions for such evolutionary PDEs.. Moreover, the importance of the opportunity to apply such a new theory to phase transitions lies in the fact that such phenomena arise in a variety of applied problems. These include melting and freezing in solid-liquid mixtures, phase changes in solids, crystal growth, soil freezing, damage in elastic materials, plasticity, food conservation, collisions, etc.. With its application, the possibility to describe these phenomena in a quantitative way has deeply ...

###### Formulations of two phase liquid gas compositional Darcy flows with phase transitions

In this article, three formulations of two phase compositional Darcy flows taking into account phase transitions are compared. The first formulation is the so called natural variable formulation commonly used in reservoir simulation, the second has been introduced in [14] and uses the phase pressures, saturations and component fugacities as main unknowns, and the third is an extension to general compositional two phase flows of the pressure pressure formulation introduced in [2] in the case of two compo-nents. The three formulations are shown to lead to equivalent definitions of the phase transitions for our gas liquid thermodynamical model. Then, they are compared numerically in terms of solution and convergence of the Newton type non linear solver on several 1D and 3D test cases including gas appearance and liquid disappearance. The 3D discretization is based on the Vertex Approximate Gradient (VAG) scheme [10] and takes into account discontinuous capillary pressures.

In this work, we analyzed the experimental pressuretemperature behavior in the isotropicnematic

**phase transition**for the liquid crystal p-azoxianisol at 1 atm by using different Convex Peg models (HERSW, HERSWS and HERSWE). Additionally, we proposed a new development for the HERSW and HERSWE models. The values of the molecular volumes of the hard and attractive cores used in these models were obtained from theoretical quantum calculations at B3LYP/6-311++G level including the solvatation model IPCM. HERSW and HERSWS models predicted adequately the IVN triple point. For such models, we analyzed, the case when a/b = 3.5 and ? = 3.5 (model HERSWS) and the particular cases when a/b = 3.5 and a/b? = 1.75, a/b = 3.6 and a/b? = 1.8 and finally, a/b = 3.7 and a/b? = 1.85 for HERSW model. HERSWE could not predict the IVN triple point and it was not possible to analyze the experimental behavior. We found that the Convex Peg model HERSW with parameters a/b = 3.7 and a/b? = 1.85 predicts quantitatively the ...###### Phase Transitions and Renormalisation Group - Hardcover - Jean Zinn-Justin - Oxford University Press

This work tries to provide an elementary introduction to the notions of continuum limit and universality in statistical systems with a large number of degrees of freedom. The existence of a continuum limit requires the appearance of correlations at large distance, a situation that is encountered in second order phase transitions, near the critical temperature.

Interestingly, this type of liquid-liquid phase separation is very sensitive to changes in temperature, protein concentration, and pH levels.. Its an elegant way for the cell to be able to manipulate gene expression of many sequences at once, said Strom.. Other cellular structures, including some involved in disease, are also organized by phase separation.. Problems with phase separation have been linked to diseases such as dementia and certain neurodegenerative disorders, said Karpen.. He noted that as we age, biological molecules lose their liquid state and become more solid, accumulating damage along the way. Karpen pointed to diseases like Alzheimers and Huntingtons, in which proteins misfold and aggregate, becoming less liquid and more solid over time.. If we can better understand what causes aggregation, and how to keep things more liquid, we might have a chance to combat these types of disease, Strom added.. The work is a big step forward for understanding how DNA functions, but ...

The lab is interested in understanding the biophysical basis for TDP-43 aggregation and details regarding how RNA influences in vitro and in vivo phase-separation and corresponding pathogenicity. Our ultimate goal is to provide proof-of-concept data for new types of RNA medicines to combat these currently untreatable diseases. ...

This Thesis presents studies of phase transitions ocurring in porous media. The investigated phase transitions include melting/crystallization, surface pre-melting and liquid-liquid phase separation of binary mixtures. A combination of NMR techniques, already existing and newly developed and ranging from cryoporometry to elaborate self-diffusion and spin-relaxation experiments, was applied in order to detect and quantify the effect of finite size constraints on those phase transitions. By relating the results to physico-chemical models, the difference in behaviour with respect to that of bulk was exploited and related to pore morphology and surface properties in diverse porous systems.. NMR cryoporometry is based on the detection of the melting/freezing temperature shifts with respect to those in the bulk state to obtain mean pore size and pore size distribution. We extended the size range in which this can be done in porous matrices of both hydrophilic and hydrophobic nature to a 1 μm-600 nm ...

###### Liquid-Liquid Phase Separation of Histone Proteins in Cells: Role in Chromatin Organization - Biomolecular Condensates -...

Publications related to biomolecular condensates, phase separation, llps and more. Liquid-liquid phase separation (LLPS) of proteins and nucleic acids has emerged as an important phenomenon in membraneless intracellular organization. We demonstrate that the linker histone H1 condenses into liquid-like droplets in the nuclei of HeLa cells. The droplets, observed during the interphase of the cell cycle, are colocalized with DNA-dense regions indicative of heterochromatin. In vitro, H1 readily undergoes LLPS with both DNA and nucleosomes of varying lengths but does not phase separate in the absence of DNA. The nucleosome core particle maintains its structural integrity inside the droplets, as demonstrated by FRET. Unexpectedly, H2A also forms droplets in the presence of DNA and nucleosomes in vitro, whereas the other core histones precipitate. The phase diagram of H1 with nucleosomes is invariant to the nucleosome length at physiological salt concentration, indicating that H1 is capable of partitioning

Infrared (IR) and Raman spectra of leonite-type minerals, K2Me(SO4)2·4H2O (Me = Mg, Mn, Fe), confirm a succession of structural phase transitions between 277 and 120 K. Because the orientation and dynamic behaviour of the sulphate tetrahedra undergo the most conspicuous changes during these transitions, transmission IR and Raman spectra were recorded for the SO4 bending and stretching modes from 660 to 1230 cm-1 (IR) and 350 to 1250 cm-1 (Raman), in a temperature range between 80 K and room temperature. At low temperature the leonite-type minerals show an order-disorder

On the connection between the

An explanation can be given after the work of Giordana and Saitta: the ILP covering test is NP-complete and therefore exhibits a sharp**phase transition**in its coverage probability. As the heuristic value of a hypothesis depends on the number of covered examples, the regions yes and no represent plateaus that need to be crossed during search without an informative heuristic value. Several subsequent works have extensively studied this finding by running several learning algorithms on a large set of artificially generated problems and argued that the occurrence of this**phase transition**dooms every learning algorithm to fail to identify the target concept.

###### Difference between revisions of Nematic Phase transitions in Mixtures of Thin and Thick Colloidal Rods - Soft-Matter

Fraden et al. and Teramoto et al. have studied the entropy driven

**phase transition**of monodisperse suspensions of purely repulsive rods from an isotropic to an aligned nematic phase experimentally. [1-2] The**phase transition**has also been studied theoretically and computationally. [3-5] For Fraden et al. the motivation to study hard particle binary mixtures of multiple aspect ratios stems from the desire to ultimately understand the impact of polydispersity on the phase separation of concentrated suspensions of rodlike macromolecules. F-actin, microtubules, and DNA are all examples of biological rodlike particles in which length and diameter polydispersity are common. Theoretical studies of binary hard-rod mixtures predict that in addition to isotropicnematic (I-N) coexistence, isotropic-nematic-nematic (I-N-N), isotropic-isotropic (I-I), and nematic-nematic (N-N) coexistence are possible when the length or diameter ratios of the particles are large enough [6 -12]. Fraden et al. have presented ...###### hep-th/0606120v4] Phase transitions, double-scaling limit, and topological strings

Abstract: Topological strings on Calabi--Yau manifolds are known to undergo phase transitions at small distances. We study this issue in the case of perturbative topological strings on local Calabi--Yau threefolds given by a bundle over a two-sphere. This theory can be regarded as a q--deformation of Hurwitz theory, and it has a conjectural nonperturbative description in terms of q--deformed 2d Yang--Mills theory. We solve the planar model and find a

**phase transition**at small radius in the universality class of 2d gravity. We give strong evidence that there is a double--scaled theory at the critical point whose all genus free energy is governed by the Painlevé I equation. We compare the critical behavior of the perturbative theory to the critical behavior of its nonperturbative description, which belongs to the universality class of 2d supergravity. We also give evidence for a new open/closed duality relating these Calabi--Yau backgrounds to open strings with framing ...###### Growth Structures and Phase Formation in Industrially Room-Temperature Pulsed Laser Deposited FCC Ti-Based Nitride Coatings

###### The boundary of the N=90 shape phase transition: 148Ce - Surrey Research Insight Open Access

The even-even N=90 isotones with Z=60-66 are known to undergo a first order

**phase transition**. Such a**phase transition**in atomic nuclei is characterized by a sudden change of the shape of the nucleus due to changes in the location of the potential minimum. In these proceedings we report a measurement of the B4/2 ratio of 148Ce, which will probe the location of the low-Z boundary of the N=90 phase transitional region. The measured B4/2 value is compared to the prediction from the X(5) symmetry within the interacting boson model at the critical point between the geometrical limits of vibrators and rigid/axial rotors. The EXILL&FATIMA campaign took place at the high-flux reactor of the Institut Laue Langevin, Grenoble, were 235U and 241Pu fission fragments were measured by a hybrid spectrometer consisting of high-resolution HPGe and fast LaBr3(Ce)-scintillator detectors. The fast LaBr3(Ce) detectors in combination with the generalized centroid difference method allowed lifetime measurements in the ...###### 0706.3388] A Confining Strong First-Order Electroweak Phase Transition - CosmoCoffee

In the Randall-Sundrum model where the radion is stabilized by a Goldberger-Wise (GW) potential there is a supercooled transition from a deconfined to a confined phase at temperatures orders of magnitude below the typical Standard Model critical temperature. When the Higgs is localized at the IR brane the electroweak

**phase transition**is delayed and becomes a strong first-order one where the Universe expands by a few e-folds. This generates the possibility of having the out-of-equilibrium condition required by electroweak baryogenesis in the electroweak**phase transition**. We have studied numerically the region of the GW parameter space where the theory is consistent and the latter possibility is realized. We have found that in most of the parameter space the nucleation temperature is so low that sphalerons are totally inactive inside the bubbles. The condition for sphalerons to be inactive after reheating imposes an upper bound on the reheating temperature that is weaker for heavy Higgs bosons so ...###### Pressure-Induced Phase Transitions in AB2X4 Chalcogenide Compounds - Francisco Javier Manjon, Veaceslav Ursaki, Ion Tiginyanu -...

With decreasing temperature, the monoclinic I2/c crystal structure of γ-Ti3O5 was found to switch to a monoclinic P2/a crystal structure of δ-Ti3O5 due to lowering of symmetry. Electrical conductivity (σ) measurement shows that γ-Ti3O5 behaves like a metallic conductor with a σ value of 4.7 S cm-1 at 320 K, while δ-Ti3O5 shows a semiconductive property with a ...###### Timothy Nott | New College

Phase transitions are found everywhere in nature, and I am interested in understanding how living cells harness them to generate chemically distinct subcellular environments. Whereas 2D phase transitions are thought to organise the membranes that encapsulate organelles such as lysosomes, endosomes, and the endoplasmic reticulum, 3D liquid-liquid phase transitions produce membraneless organelles such as nucleoli, Cajal bodies, P-granules and nuage. These membraneless organelles behave as tiny liquid droplets suspended inside the cell, and can rapidly condense and dissolve with changes in the cell-cycle, or in response to stresses such as viral infection. I am particularly interested in uncovering the molecular details of how membraneless organelles are formed in cells, and in how the unique solvent environment of their interior influences biochemical reactions.. ...

###### Chemistry - Phase Transitions

If we stop heating during melting and place the mixture of solid and liquid in a perfectly insulated container so no heat can enter or escape, the solid and liquid phases remain in equilibrium. This is almost the situation with a mixture of ice and water in a very good thermos bottle; almost no heat gets in or out, and the mixture of solid ice and liquid water remains for hours. In a mixture of solid and liquid at equilibrium, the reciprocal process of melting and freezing occur at equal rates, and the quantities of solid and liquid therefore remain constant. The temperature at which the solid and liquid phases of a given substance are in equilibrium is called the melting point of the solid or the freezing point of the liquid. Use of one term or the other is normally dictated by the direction of the

One of the central challenges in condensed matter physics is to understand how different phases of matter can arise and how these phases can be characterized. A most simple example is of course provided by the three states of water, i.e. solid ice, liquid water and gaseous vapor. These three phases are distinguished from another by well-defined transitions. In the quantum realm, such

**phase transition**exists as well and give rise to many properties of the world in which we live. Phenomena such as, e.g., magnetism and superconductivity are prime examples which are well known. In recent years, other, so-called quantum phase transitions, have been added to the zoo of transitions. One such example, disorder-induced localisation embodies the paradigmatic example of a quantum**phase transition**, i.e. driven by the quantum wave-like nature of matter. Conventionally, the study of phase transitions is tedious because right at the transition, fluctuations from equilibrium dominate, making analytic and ...###### Physics-inspired algorithms and phase transitions in community detection | Math

Detecting communities, and labeling nodes, is a ubiquitous problem in the study of networks. Recently, we developed scalable Belief Propagation algorithms that update probability distributions of node labels until they reach a fixed point. In addition to being of practical use, these algorithms can be studied analytically, revealing phase transitions in the ability of any algorithm to solve this problem. Specifically, there is a detectability transition in the stochastic block model, below which no algorithm can label nodes better than chance. This transition was subsequently established rigorously by Mossel, Neeman, and Sly, and Massoulie.Ill explain this transition, and give an accessible introduction to Belief Propagation and the analogy with free energy and the cavity method of statistical physics. Well see that the consensus of many good solutions is a better labeling than the best solution --- something that is true for many real-world optimization problems. While many algorithms ...

###### 1806.01719] Long-time behaviour and phase transitions for the McKean--Vlasov equation on the torus

Abstract: We study the McKean-Vlasov equation \[ \partial_t \varrho= \beta^{-1} \Delta \varrho + \kappa \nabla \cdot (\varrho \nabla (W \star \varrho)) \, , \] with periodic boundary conditions on the torus. We first study the global asymptotic stability of the homogeneous steady state. We then focus our attention on the stationary system, and prove the existence of nontrivial solutions branching from the homogeneous steady state, through possibly infinitely many bifurcations, under appropriate assumptions on the interaction potential. We also provide sufficient conditions for the existence of continuous and discontinuous phase transitions. Finally, we showcase these results by applying them to several examples of interaction potentials such as the noisy Kuramoto model for synchronisation, the Keller--Segel model for bacterial chemotaxis, and the noisy Hegselmann--Krausse model for opinion dynamics ...

###### 2006.15087] Finding and classifying an infinite number of cases of the practically perfect phase transition in an Ising model...

Abstract: Very recently, the discovery of a marginal, or practically perfect,

**phase transition**(MPT or PPPT) at finite temperature in the 2-leg ladder Ising model with trimer rungs was reported [1]. The MPT or PPPT stems from a new mathematical structure that has not appeared before in phase-transition problems. This opens the door to simulations and utilizations of the spontaneous phase-transition phenomena in one-dimensional systems, despite the proof that phase transitions do not exist in the one-dimensional Ising models with short-range interactions back to year 1924 [2]. Naturally, the urgent fundamental and practical question is how we, now guided by the new light on phase transitions, can find the next cases of MPT or PPPT in one-dimensional systems. Here, I present a generalization of the original idea to a new parents-children Ising model with ice-cream-cone rungs, and exactly prove that the model possesses the same mathematical structure and thus MPT or PPPT. Yet, the ice-cream-cone ...###### Nuit Blanche: Phase Transitions of Spectral Initialization for High-Dimensional Nonconvex Estimation

We study a spectral initialization method that serves a key role in recent work on estimating signals in nonconvex settings. Previous analysis of this method focuses on the phase retrieval problem and provides only performance bounds. In this paper, we consider arbitrary generalized linear sensing models and present a precise asymptotic characterization of the performance of the method in the high-dimensional limit. Our analysis also reveals a

**phase transition**phenomenon that depends on the ratio between the number of samples and the signal dimension. When the ratio is below a minimum threshold, the estimates given by the spectral method are no better than random guesses drawn from a uniform distribution on the hypersphere, thus carrying no information; above a maximum threshold, the estimates become increasingly aligned with the target signal. The computational complexity of the method, as measured by the spectral gap, is also markedly different in the two phases. Worked examples and numerical ...###### PDF] PHASE TRANSITIONS IN SOCIAL SCIENCES: TWO-POPULATION MEAN FIELD THEORY | Semantic Scholar

A new mean field statistical mechanics model of two interacting groups of spins is introduced, and the

**phase transition**is studied in terms of their relative size. A jump of the average magnetization is found for large values of the mutual interaction when the relative percentage of the two populations crosses a critical threshold. It is shown how the critical percentage depends on internal interactions and on the initial magnetizations. The model is interpreted as a prototype of resident-immigrant cultural interaction, and conclusions from the social sciences perspectives are drawn.###### EXTRA Probability Seminar presents Topological phase transitions in random geometric complexes | Stanford EE

Connectivity and percolation are two well studied phenomena in random graphs. In this talk we will discuss higher-dimensional analogues of connectivity and percolation that occur in random simplicial complexes. Simplicial complexes are a natural generalization of graphs, that consist of vertices, edges, triangles, tetrahedra, and higher-dimensional simplexes. We will mainly focus on random geometric complexes. These complexes are generated by taking the vertices to be a random point process, and adding simplexes according to their geometric configuration. Our generalized notions of connectivity and percolation use the language of homology-an algebraic-topological structure representing cycles of different dimensions. In this talk we will discuss recent results analyzing phase transitions related to these topological phenomena ...

###### Search Results for phase-diagrams | AKJournals

The effect of cure temperature and modifier proportion on the miscibility of an epoxy-amine system with a thermoplastic modifier was studied by analysis of phase diagrams, morphologies, and glass transitions. Phase diagrams for the system before and during reaction were obtained from a thermodynamic analysis of phase separation using a model based on Flory-Huggins theory. Different types of morphologies were observed and analyzed in function of cure temperature and modifier proportion. The validity of the thermodynamic model was checked by comparing with observed morphologies. Two glass transitions were observed for most of the modified systems indicating that a phase separation was occurred. ...

It is one thing to figure out that a graph is sparse - Duh! the number of moderators is low- it is yet another to figure out the dynamics between the sparse set of unpaid and volunteer moderators, the inner group of paid admins at Reddit and the rest of the much denser community. The fate of Reddit hinges on its ability to mend fences between the first two communities while at the same time pleasing the third community. The first question one should ask is whether Reddit has the ability to build links and trust so that they get away from a perilious metastable region. The second question is algorithmic, as shown by Lenka and colleagues: if the wrong spectral operator is used to figure out the dynamics of these graphs, you might be over/underestimating by a large margin the efforts it takes to get away from this metastable region ...
