The robustness or breakdown of Lotka’s law about the frequency distribution of scientific productivity depends on scientific cooperation, counting methods, interdisciplinary publishing and selection methods for sample collections. We have chosen to analyse the relationship using Mandelbrot’s equivalent distribution model because this model is sensitive and uses the original data (scores). Five ...

where we would need to substitute consistent estimates of the conditional probability Pr(Y |X = x, S = s) and the marginal probability Pr(S = s). It is sometimes useful to short-cut having to estimate the marginal probability by using the law of large numbers. Notice that, with respect to the sum over s, Pr(Y |X = x, S = s) is just some function of s. If we have an IID sample of realizations of...

Using both a recent calculation by Bruch of the damping of the motion of a monolayer nitrogen film oscillating harmonically on a metallic surface due to Ohm's law heating and a Thomas-Fermi approximation treatment of the Ohm's law heating mechanism, which accounts for the nonzero thickness of the surface region of a metal, it is argued that this mechanism for friction is able to account for rec...

We consider a family of nonlocal capillarity models, where surface tension is modeled by exploiting the family of fractional interaction kernels |z|−n−s, with s ∈ (0, 1) and n the dimension of the ambient space. The fractional Young’s law (contact angle condition) predicted by these models coincides, in the limit as s → 1−, with the classical Young’s law determined by the Gauss free energy. Her...

compared to experimental and human sciences, law has never been productive but it has always utilized the results and information obtained through other sciences, psychology in particular. therefore, new psychological findings about memory and age could both and must be taken into account in law as concerns interpretation and making judgment. psychological findings show judges rely on the testi...

the aim of this research is to determine the core journals in hamadan university of medical sciences with bradford's law of scattering. survey method, bibliometrics and bradford's law are used in this research. research population consists of all subscribed journals of hamadan university of medical sciences in 2004-006. research results show that 109 journals (74.7 percent of all jour...

computer spying is considered as a crime, inducing computer as a criminal subject and material part of it. it is not possible, before discovering computer, so, most countries have no passed rules a bout it. internal law of our country has investigated activities such as illegal attaining into secret data ,damaging security and national interests 'in case of disclosing them, as computer spy...

RATIONALE Lower airway (LAW) infection with Pseudomonas aeruginosa and Staphylococcus aureus is the leading cause of morbidity in cystic fibrosis (CF). The upper airways (UAW) were shown to be a gateway for acquisition of opportunistic bacteria and to act as a reservoir for them. Therefore, tools for UAW assessment within CF routine care require evaluation. OBJECTIVES The aims of the study we...

the social situation of medieval britain prior to its conquest by william,duke of normandy, in 1066 ad was so retarded. but, soon after that it wasprovided with such a great legal institutions and culture that, even today,give rise to a great surprise as to their magnificence, causing admirations byscholars. but, it raises queries regarding the original source of those legalinstitutions, for wh...

the study examines the relationship between the size of firms and their growth in iranian food and beverages industries. the study utilizes iranian industrial data, classified on the base of isic with 4-digit code. the study evaluates the validity of gibrat's law in the selected firms. the validity of the law has been examined by two methods. first, the panel analysis is applied and second...
