Password Authentication with Insecure Communication

by Leslie Lamport , 1981
"... A method of user password authentication is de-scribed which is secure even if an intruder can read the system's data, and can tamper with or eavesdrop on the communication between the user and the system. The method assumes a secure one-way encryption function and can be implemented with a mi ..."

In vivo gene delivery and stable transduction of nondividing cells by a lentiviral vector

by Luigi Naldini, Ulrike Blomer, Daniel Ory, Richard Mulligan, Fred H. Gage, Inder M. Verma, Didier Trono - Science , 1996
"... A retroviral vector system based on the human immunodeficiency virus (HIV) was de-veloped that, in contrast to a murine leukemia virus-based counterpart, transduced heterologous sequences into HeLa cells and rat fibroblasts blocked in the cell cycle, as well as into human primary macrophages. Additi ..."

Crystal structure of rhodopsin: a G protein-coupled receptor

by Krzysztof Palczewski, Takashi Kumasaka, Tetsuya Hori, Craig A. Behnke, Hiroyuki Motoshima, Brian A. Fox, Isolde Le Trong, David C. Teller, Tetsuji Okada, Ronald E. Stenkamp, Masaki Yamamoto, Masashi Miyano - LeTrong I, Teller DC, Okada T, Stenkamp RE et , 2000
"... Heterotrimeric guanine nucleotideÐbinding protein (G protein)Ðcoupled recep-tors (GPCRs) respond to a variety of different external stimuli and activate G proteins. GPCRs share many structural features, including a bundle of seven transmembrane a helices connected by six loops of varying lengths. We ..."

reCAPTCHA: Human-Based Character Recognition via Web Security Measures

by Luis Von Ahn, Benjamin Maurer, Colin Mcmillen, David Abraham, Manuel Blum , 2008
"... widespread security measures on the World Wide Web that prevent automated programs from abusing online services. They do so by asking humans to perform a task that computers cannot yet perform, such as deciphering distorted characters. Our research explored whether such human effort can be channeled ..."

of professional human transcribers. Our apparatus is deployed in more than 40,000 Web sites and has transcribed over 440 million words. ACAPTCHA (1, 2) is a challenge response test used on the World Wide Web to de termine whether a user is a human or a computer. The acronym stands for Completely Automated Public

Parametric Integer Programming

by Paul Feautrier - RAIRO Recherche Op'erationnelle , 1988
"... When analysing computer programs (especially numerical programs in which arrays are used extensively), one is often confronted with integer programming problems. These problems have three peculiarities: ffl feasible points are ranked according to lexicographic order rather than the usual linear ec ..."

in handling lexicographic ordering; ffl the algorithm may be executed in symbolic mode, thus giving the solution of continuous parametric problems; ffl the method may be extended to problems in integers. We prove that the resulting algorithm always terminate and give an estimate of its complexity. R

Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.

by Robert J Vallerand , Michelle S Fbrtier , Frederic Guay - Journal of Personality and Social Psychology, , 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

The telomere terminal transferase of Tetrahymena is a ribonucleoprotein enzyme with two kinds of primer specificity

by Carol W. Greider, Elizabeth H. Blackburn - Cell , 1987
"... We have analyzed the de novo telomere synthesis catalyzed by the enzyme telomere terminal transfer-ase (telomerase) from Tetrahymena. Oligonucleotides representing the G-rich strand of telomeric sequences from five different organisms specifically primed the addition of TTGGGG repeats in vitro, sugg ..."

ASSESSMENT OF ATMOSPHERIC IMPACTS ON HUMAN BEINGS IN A RE-GIONAL SCALE

by H. Mayer, A. Matzarakis
"... Methods of human-biometeorology have to be applied for the assessment of atmospheric impacts on human beings. Among the human-biometeorological effective complexes two are of great importance in the regional scale: the ther-mal effective complex and the air quality effective complex. A procedure for ..."
