Louxin Zhang
Louxin Zhang is a Canadian computational biologist. He is currently a professor in the Department of Mathematics at the National University of Singapore. He is recognized for his contributions to combinatorial semigroup theory in mathematics. In addition, he is recognized for his work on the mathematical understanding of phylogenetic trees and networks, as well as the analysis of spaced seeds for sequence comparison in bioinformatics. Early life Louxin Zhang grew up in Luoyang, Henan, China. He graduated from Lanzhou University with an undergraduate degree in mathematics and a master's degree in mathematics. Then he proceeded to Canada to pursue a doctorate in computer science at the University of Waterloo, where he earned his Ph.D. in Computer Science with a thesis entitled "Emulations and Embeddings of Meshes of Trees and Hypercubes of Cliques. Career After postdoctoral research in the laboratory of Ming Li, Zhang began his independent research career in 1996 at the Institu ...

National University Of Singapore
The National University of Singapore (NUS) is a national university, national Public university, public research university in Singapore. It was officially established in 1980 by the merging of the University of Singapore and Nanyang University. The university offers degree programmes in disciplines at both the undergraduate and postgraduate levels, including in the sciences, medicine and dentistry, design and environment, law, arts and social sciences, engineering, business, computing, and music. NUS's main campus is located adjacent to the Kent Ridge subzone of Queenstown, Singapore, Queenstown. The Duke–NUS Medical School is located at the Outram, Singapore, Outram campus. The Bukit Timah campus houses the National University of Singapore Faculty of Law, Faculty of Law and Lee Kuan Yew School of Public Policy. NUS's affiliated faculty members and researchers include one Nobel Prize laureate, one Tang Prize laureate, and one Vautrin Lud Prize, Vautrin Lud laureate. History ...

Conjugacy Problem
In abstract algebra, the conjugacy problem for a group ''G'' with a given presentation is the decision problem of determining, given two words ''x'' and ''y'' in ''G'', whether or not they represent conjugate elements of ''G''. That is, the problem is to determine whether there exists an element ''z'' of ''G'' such that :y = zxz^.\,\! The conjugacy problem is also known as the transformation problem. The conjugacy problem was identified by Max Dehn in 1911 as one of the fundamental decision problems in group theory; the other two being the word problem and the isomorphism problem. The conjugacy problem contains the word problem as a special case: if ''x'' and ''y'' are words, deciding if they are the same word is equivalent to deciding if xy^ is the identity, which is the same as deciding if it's conjugate to the identity. In 1912 Dehn gave an algorithm that solves both the word and conjugacy problem for the fundamental groups of closed orientable two-dimensional manifolds of g ...

People From Luoyang
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession. Indeed, judge Ivor Jennings i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computational Biologists
A computation is any type of arithmetic or non-arithmetic calculation that is well-defined. Common examples of computation are mathematical equation solving and the execution of computer algorithms. Mechanical or electronic devices (or, historically, people) that perform computations are known as ''computers''. Computer science is an academic field that involves the study of computation. Introduction The notion that mathematical statements should be 'well-defined' had been argued by mathematicians since at least the 1600s, but agreement on a suitable definition proved elusive. A candidate definition was proposed independently by several mathematicians in the 1930s. The best-known variant was formalised by the mathematician Alan Turing, who defined a well-defined statement or calculation as any statement that could be expressed in terms of the initialisation parameters of a Turing machine. Other (mathematically equivalent) definitions include Alonzo Church's '' lambda-definabilit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Loss
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human evolution. Origin of apes Biologists classify humans, along with only a few other species, as great apes (species in the family Family (from ) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). It forms the basis for social order. Ideally, families offer predictabili ... Hominidae). The living Hominidae include two distinct species of Pan (genus), chimpanzee (the bonobo, ''Pan paniscus'', and the chimpanzee, ''Pan troglodytes''), two species of gorilla (the western gorilla, ''Gorilla gorilla'', and the eastern gorilla, ''Gorilla grauer ...
