Ultra dense networks (UDN) are identified as one of the key enablers for 5G, since they can provide an ultra high spectral reuse factor exploiting proximal transmissions. By densifying the network infrastructure equipment, it is highly possible that each user will have one or more dedicated serving base station antennas, introducing the user-centric virtual cell paradigm. However, due to irregular deployment of a large amount of base station antennas, the interference environment becomes rather complex, thus introducing severe interferences among different virtual cells. This paper focuses on the downlink transmission scheme in UDN where a large number of users and base station antennas is uniformly spread over a certain area. An interference graph is first created based on the large-scale fadings to give a potential description of the interference relationship among the virtual cells. Then, base station antennas and users in the virtual cells within the same maximally-connected component are grouped

The question how living biological cells adapt their local or global mechanical properties when they have to move or deform, is intriguing and a field of intensive study worldwide.

Here, we show that the multikinase inhibitor SO alone diminishes pancreatic CSC-like tumor cells, but depletes them significantly only in combination with the phytochemical SF. The major CSC characteristics of the CSChigh MIA-PaCa2 and CSClow BxPc-3 cell lines have been described in our recent study (6). In the present work, we describe the presence of two cell populations, which can be found in CSChigh but not in CSClow cells, namely, spheroidal cells and fibroblast-like adherent cells. These two populations may correspond to primitive CSCs and differentiated daughter cells, suggesting differentiation potential of in vitro cultured pancreatic CSCs. SO targeted both cell subpopulations present in the CSChigh cell line in vitro. This was due to the induction of apoptosis, DNA fragmentation, and downregulation of antiapoptotic proteins. In addition, SO strongly diminished clonogenicity, spheroid formation, and ALDH1 activity. Most importantly, the concentration of 20 μmol/L SO was selectively ...

Genome Project scientists say creating life-saving drugs isnt as easy as knowing all the genes in a human being -- they need a eureka technology to turn a mess into knowledge. Some are yelling Eureka! right now. By Kristen Philipkoski.

Honesty compels me to add that I was a member of the committee that wrote the current (1983) IUPAC-IUB Recommendations on Nomenclature and Symbolism for Amino Acids and Peptides, in which you will find, in Table 1, the words The systematic names and formulas given refer to hypothetical forms in which amino groups are unprotonated and carboxyl groups are undissociated. This convention is useful to avoid various nomenclatural problems but should not be taken to imply that these structures represent an appreciable fraction of the amino-acid molecules. I tried but failed to convince the rest of the committee that hypothetical was a euphemism that should be replaced by fictitious or nonexistent. After more than 30 years its hard to be certain, but I think the second sentence had not originally been in the draft but was added in an effort to keep me quiet. To be fair to the committee, I think the rest of the document shows correct structures, except for lapse with glutathione.. Delete ...

In this PhD, we present some algorithms and complexity results for two general problems that arise in the analysis of a metabolic network: the search for elementary modes of a network and the search for minimal precursors sets. Elementary modes is a common tool in the study of the cellular characteristic of a metabolic network. An elementary mode can be seen as a minimal set of reactions that can work in steady state independently of the rest of the network. It has therefore served as a mathematical model for the possible metabolic pathways of a cell. Their computation is not trivial and poses computational challenges. We show that some problems, like checking consistency of a network, finding one elementary mode or checking that a set of reactions constitutes a cut are easy problems, giving polynomial algorithms based on LP formulations. We also prove the hardness of central problems like finding a minimum size elementary mode, finding an elementary mode containing two given reactions, counting the

PAOLO FRIL, chairman and chief scientific officer of GeneDupe, based in San Melito, California, is a man with a dream. That dream is a dragon in every home.. GeneDupes business is biotech pets. Not for Dr Fril, though, the mundane cloning of dead moggies and pooches. He plans a range of entirely new animals or, rather, of really quite old animals, with the twist that even when they did exist, it was only in the imagination.. Making a mythical creature real is not easy. But GeneDupes team of biologists and computer scientists reckon they are equal to the task. Their secret is a new field, which they call virtual cell biology . Biology and computing have a lot in common, since both are about processing information in one case electronic; in the other, biochemical. Virtual cell biology aspires to make a software model of a cell that is accurate in every biochemical detail. That is possible because all animal cells use the same parts list mitochondria for energy processing, the endoplasmic ...

Several problems regarding cell motility and morphogenesis are characterized by the contemporary presence of cells that behave as single entities and cells that follow and cluster around them. From the mathematical point of view, describing such phenomena requires the development of mathematical models in which virtual cells can switch from a discrete to a continuous description. Keeping this in mind, the talk aims at presenting some ideas on how to do that, making for instance use of measure theory or introducing the concept of bubble functions ...

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future.. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.. Protocells are the simplest, most primitive living systems, you can think of. The oldest ancestor of life on Earth was a protocell, and when we see, what it eventually managed to evolve into, we understand why science is so fascinated with protocells. If science can create an artificial protocell, we get a very basic ingredient for creating more advanced artificial life.. However, creating an artificial protocell is far from simple, and so far no one has managed to do that. One of the challenges is to create the information strings that can be inherited by cell offspring, including protocells. Such information strings are like modern DNA or RNA ...

Cell cycle models used in biology can be very complex. These models have parameters with initially unknown values. The values of the parameters vastly aect the accuracy of the models in representing real biological cells. Typically people search for the best parameters to these models using computers only as tools to run simulations. In this thesis methods and results are described for a computer program that searches for parameters to a series of related models using well tested algorithms. The code for this program uses ODRPACK for parameter estimation and LSODAR to solve the dierential equations that comprise the model ...

Recent experimental work in the field of synthetic protocell biology has shown that prebiotic vesicles are able to steal lipids from each other. This phenomenon is driven purely by asymmetries in the physical state or composition of the vesicle membranes, and, when lipid resource is limited, translates directly into competition amongst the vesicles. Such a scenario is interesting from an origins of life perspective because a rudimentary form of cell-level selection emerges. To sharpen intuition about possible mechanisms underlying this behaviour, experimental work must be complemented with theoretical modelling. The aim of this paper is to provide a coarse-grain mathematical model of protocell lipid competition. Our model is capable of reproducing, often quantitatively, results from core experimental papers that reported distinct types vesicle competition. Additionally, we make some predictions untested in the lab, and develop a general numerical method for quickly solving the equilibrium ...

This article was originally published in UCLA Samueli Newsroom. Researchers at the UCLA Samueli School of Engineering have discovered a new artificial intelligence-based method to discern the properties of live biological cells without destroying them. The advance could enable laboratories to conduct drug-safety screening faster and more efficiently while improving quality control for cell therapies.. The research was published today in Natures Scientific Reports.. We want to know if a batch of live biological cells can be both viable and able to perform the functions we want them to. This noninvasive, AI-backed technique can infer the quality of those cells while keeping the entire batch intact, said study leader Neil Lin, an assistant professor of mechanical and aerospace engineering. We envision this method could be widely adopted by many academic and industrial cell biology labs. And it could be especially important in cell therapies, where the cells themselves are valuable.. Currently, ...

Newly formed protocell. Image 2 of 5. Artwork showing cellular components inside a basic cell membrane. This protocell (artificial cell) was formed from a synthetic primeval soup containing PNA (peptide nucleic acid, orange), fatty acids (blue) and lysosomes (enzyme-producing organelles, yellow). The primeval soup was a mix of carbon based molecules that chemically evolved to form simple cells, at the beginning of life. Scientists at Los Alamos National Laboratory in New Mexico, USA, attempted to recreate this in 2006 by making protocells. Here, the loose components have arranged themselves into an ordered structure resembling a simple cell.

Title: Stochastic analysis of biochemical reaction networks with absolute concentration robustness Abstract: It has recently been shown that structural conditions on the reaction network, rather than a fine-tuning of system parameters, often suffice to impart absolute concentration robustness on a wide class of biologically relevant, deterministically modeled mass-action systems [Shinar and Feinberg, Science, 2010]. Many biochemical networks, however, operate on a scale insufficient to justify the assumptions of the deterministic mass-action model, which raises the question of whether the long-term dynamics of the systems are being accurately captured when the deterministic model predicts stability. I will discuss recent results that show that fundamentally different conclusions about the long-term behavior of such systems are reached if the systems are instead modeled with stochastic dynamics and a discrete state space. Specifically we characterize a large class of models which exhibit ...

Living Systems has seven units -- The Nature of Biology, Energy and the Cell, The Continuation of Life, Evolutionary Relationships, Life Functions of Organisms, Controlling Living Systems and Interactions in the Environment. Those are nice titles, but they give only a poor idea of the books content, and they dont convey what the book really is about. At bottom, Living Systems is a book about humans. Indeed, I suspect that it may have originated as an attempt to get some new mileage out of a mass of old material that dealt with human anatomy and physiology. Sure, the book mentions other organisms, and the paste-pushers have thrown in some chapters that purport to tell about evolution and ecology and what-have-you, but the result is silly. The material about evolution and ecology is hopelessly dumb and does little to divert attention from the books anthropocentric stance, and I doubt that anyone who really reads Living Systems will mistake it for a general-biology text.

The concept of identity is used both (i) to distinguish a system as a particular material entity that is conserved as such in a given environment (token-identity: i.e., identity as permanence or endurance over time), and (ii) to relate a system with other members of a set (type-identity: i.e., identity as an equivalence relationship). Biological systems are characterized, in a minimal and universal sense, by a highly complex and dynamic, far-from-equilibrium organization of very diverse molecular components and transformation processes (i.e., genetically instructed cellular metabolisms) that maintain themselves in constant interaction with their corresponding environments, including other systems of similar nature. More precisely, all living entities depend on a deeply convoluted organization of molecules and processes (a naturalized von Neumann constructor architecture) that subsumes, in the form of current individuals (autonomous cells), a history of ecological and evolutionary interactions (across
