To find the essential prime implicants, we run along the top row. We have to look for columns with only 1 "✓". If a column has only 1 "✓", this means that the minterm can only be covered by 1 prime implicant. This prime implicant is essential. For example: in the first column, with minterm 4, there is only 1 "✓". This means that m(4,12) is essential. So we place a star next to it. Minterm 15 also has only 1 "✓", so m(10,11,14,15) is also essential. Now all columns with 1 "✓" are covered. The second prime implicant can be 'covered' by the third and fourth, and the third prime implicant can be 'covered' by the second and first, and neither is thus essential. If a prime implicant is essential then, as would be expected, it is necessary to include it in the minimized boolean equation. In some cases, the essential prime implicants do not cover all minterms, in which case additional procedures for chart reduction can be employed. The simplest "additional procedure" is trial and error, but a ...
MS Caribbean Princess is a modified Grand Class cruise ship owned and operated by Princess Cruises, with a capacity of over 3,600 passengers, the largest carrying capacity in the Princess fleet until June 2013 when the new Royal Princess, another Princess ship superseded its record. She has 900 balcony staterooms and a deck of mini-suites. She was the first modern cruise ship with an outdoor theater, which Princess bills as "Movies Under The Stars". Caribbean Princess is slightly larger than the other ships in her class (Star Princess, Golden Princess, and Grand Princess), due to the addition of an additional deck of cabins called the Riviera deck. Another difference is that, being initially designed to cruise the Caribbean year-round, there is no sliding roof over the pool area for shelter in poor weather. On March 12, 2012, Caribbean Princess suffered an issue to her port side propulsion engine, which required her to return to her home port of San Juan, Puerto Rico after a ...
In 2001 the Triebel group identified a LAG3-associated protein, called LAP, that seemed to participate in immune system down-regulation. Also in 2001 the Triebel group reported finding LAG3 expression on CD8+ tumor-infiltrating lymphocytes, with this LAG3 contributing to APC activation. In August 2002 the first phenotypic analysis of the murine LAG-3 was reported by a team at St. Jude Children's Research Hospital in Memphis. Molecular analysis reported by the St. Jude Children's Research Hospital team in November 2002 demonstrated that the inhibitory function of LAG-3 is performed via the protein's cytoplasmic domain. In 2003 the Triebel group was able to identify the MHC class II signal transduction pathways in human dendritic cells induced by LAG3. while the St. Jude Children's Research Hospital team showed that the absence of LAG3 caused no defect in T cell function. In May 2004 the St. Jude Children's Research Hospital team showed, through LAG3 knockout mice, that ...

... is a complication of diabetes. It is caused by infarcted muscle tissue, usually in the thigh. The mean age at presentation is thirty-seven years with a reported range of nineteen to sixty-four years. The mean age of onset since diagnosis of diabetes is fifteen years. The female:male ratio is 1.3:1. Other diabetic complications such as nephropathy, neuropathy, retinopathy and hypertension are usually present. Its major symptom is the acute onset muscle pain, usually in the thigh, in the absence of trauma. Signs include exquisite muscle tenderness and swelling. Tissue biopsy is the gold standard. Macroscopically this reveals pale muscle tissue. Microscopically infarcted patches of myocytes. Necrotic muscle fibers are swollen and eosinophilic and lack striations and nuclei. Small-vessel walls are thickened and hyalinized, with luminal narrowing or complete occlusion. Biopsy cultures for bacteria, fungi, acid-fast bacilli and stains are negative in simple myonecrosis.

... is a series of epistolary young adult novels written by Meg Cabot, and is also the title of the first volume, published in 2000. The series revolves around Amelia 'Mia' Thermopolis, a teenager in New York who discovers that she is the princess of a small European principality called Genovia. Meg Cabot quotes the series' inspiration on her website stating: "I was inspired to write The Princess Diaries when my mom, after the death of my father, began dating one of my teachers; they later went on to get married just as Mia's mom does in the book! I have always had a 'thing' for princesses (my parents used to joke that when I was smaller, I did a lot of insisting that my 'real' parents, the king and queen, were going to come get me soon, and that everyone had better start being a LOT nicer to me) so I stuck a princess in the book just for kicks... and VOILÀ! The Princess Diaries was born." The books are noted for containing many popular culture references, which include ...

A teoría da resposta antitumoral do sistema inmunitario in vivo foi recoñecida polo físico William B. Coley. En 1968, o Dr. Gale A Granger da Universidade de California, Irvine, informou do descubrimento dun factor citotóxico producido polos linfocitos e denominouno linfotoxina (LT). O mérito deste descubrimento compartiuno coa Dra. Nancy H. Ruddle da Universidade Yale, que informou da mesma actividade nunha serie de artigos consecutivos publicados nese mesmo mes. Posteriormente, en 1975, o Dr. Lloyd J. Old do Memorial Sloan-Kettering Cancer Center, de Nova York, informou sobre outros factores citotóxicos producidos polos macrófagos e usou a denominación factor de necrose tumoral (TNF). Ambos os factores foron descritos baseándose na súa capacidade de matar células L-929 de fibrosarcoma de rato. Estes conceptos foron ampliados a doenzas sistémicas en 1981, cando Ian A. Clark, da Universidade Nacional de Australia, en colaboración con Elizabeth Carswell no grupo do Dr. Old, ...
A lipoma is a benign tumor made of fat tissue. They are generally soft to the touch, movable, and painless. They usually occur just under the skin but occasionally may be deeper. Most are less than 5 cm in size. Common locations include upper back, shoulders, and abdomen. A few people have a number of lipomas. The cause is generally unclear. Risk factors include family history, obesity, and not enough exercise. Diagnosis is typically based on a physical exam. Occasionally medical imaging or tissue biopsy is used to confirm the diagnosis. Treatment is typically by observation or surgical removal. Rarely the condition may recur following removal, however, this can generally be managed with repeat surgery. They are not generally associated with a future risk of cancer. About 2% of people are affected. Lipomas typically occur in adults between 40 to 60 years of age. Males are more often affected than females. They are the most common non-cancerous soft tissue tumor. The first use of the term ...
Complication, in medicine, is an unfavorable evolution or consequence of a disease, a health condition or a therapy. The disease can become worse in its severity or show a higher number of signs, symptoms or new pathological changes, become widespread throughout the body or affect other organ systems. A new disease may also appear as a complication to a previous existing disease. A medical treatment, such as drugs or surgery may produce adverse effects or produce new health problem(s) by itself. Therefore, a complication may be iatrogenic (i.e. literally brought forth by the physician).. Medical knowledge about a disease, procedure or treatment usually entails a list of the most common complications, so that they can be foreseen, prevented or recognized more easily and speedily.. Depending on the degree of vulnerability, susceptibility, age, health status, immune system condition, etc. complications may arise more easily. Complications affect adversely the prognosis of a disease. Non-invasive ...
In 1999, financial analyst Harry Markopolos had informed the SEC that he believed it was legally and mathematically impossible to achieve the gains Madoff claimed to deliver. According to Markopolos, it took him four minutes to conclude that Madoff's numbers did not add up, and another minute to suspect they were likely fraudulent.. After four hours of failed attempts to replicate Madoff's numbers, Markopolos believed he had mathematically proved Madoff was a fraud. He was ignored by the SEC's Boston office in 2000 and 2001, as well as by Meaghan Cheung at the SEC's New York office in 2005 and 2007 when he presented further evidence. He has since co-authored a book with Gaytri Kachroo (the leader of his legal team) titled No One Would Listen. The book details the frustrating efforts he and his legal team made over a ten-year period to alert the government, the industry, and the press about Madoff's fraud.. Although Madoff's wealth management business ultimately grew into a ...
