Abstract Simple random-sampling resolutions of the raven paradox relevantly diverge from scientific practice. We develop a stratified model, yielding better fit and apparently rehabilitating simple random sampling as legitimate idealization. However, neither accommodates second concern, objection potential bias. third model that crucially invokes causal considerations, novel resolution handles ...

I review the parametrisation of full set ?b??*(1520) form factors in framework Heavy Quark Expansion, including next-to-leading-order O(?s) and, for first time, next-to-leading-power O(1/mb) corrections. The unknown hadronic parameters are obtained by performing a fit to recent lattice QCD calculations. investigate compatibility Expansion and current data, finding tension between these two appr...

A three dimensional quantitative structure-activity relationship study using the comparative molecular field analysis method was performed on a series of 3-aryl-4-[alpha-(1H-imidazol-1-yl) aryl methyl] pyrroles for their anticandida activity. This study was performed using 40 compounds, for which comparative molecular field analysis models were developed using a training set of 33 compounds. Da...

BACKGROUND Recording and manipulating neural activity in awake behaving animal models requires long-term implantation of cranial implants that must address a variety of design considerations, which include preventing infection, minimizing tissue damage, mechanical strength of the implant, and MRI compatibility. NEW METHOD Here we address these issues by designing legless, custom-fit cranial i...

The purpose of this study was to test the compatibility theoretical and empirical structural equations on relationship between mathematical connection skills, reasoning, problem-solving abilities junior high school students. This is an ex-post facto research at SMP N 1 Bengkulu City. population 296 people, sample selected through a simple random technique 100 people. Data collection techniques ...

abstract to study the effect of nitrogen application and 2-4-d on weed density and weed architecture in winter wheat an experiment was conducted at agricultural research site, university of mohaghegh ardabili, ardabil in 2009. treatments were two nitrogen levels (no fertilizer and 150 kgnha-1 application) with or without 2-4-d (1.5 kg ai ha-1). results showed that nitrogen application had no si...

Abstract We develop a theory of finite element systems, for the purpose discretizing sections vector bundles, in particular those arising elasticity. In presence curvature, we prove discrete Bianchi identity. flat case, de Rham theorem on cohomology groups. check that some known mixed elements stress–displacement formulation elasticity fit our framework. also define, dimension two, first confor...
