The standard analysis of knowledge in contemporary epistemology is the view that a subject \(S\) knows proposition \(p\) iff 1.) true; 2.) believes \(p\); 3.) justified believing \(p\). Hence, true belief (JTB)1. second condition (propositional) entails called entailment thesis and has been considered by majority as uncontroversial. Numerous accounts have constructed involving granting it defau...

Rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. However, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. To resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...

Over the past decade, a major effort was made to miniaturize engineered tissues, as to further improve the throughput of such approach. Most existing methods for generating microtissues thus rely on T-shaped cantilevers made by soft lithography and based on the use of negative SU-8 photoresist. However, photopatterning T-shaped microstructures with these negative photoresists is fastidious and ...

Haloferax volcanii pre-tRNA(Trp) processing requires box C/D ribonucleoprotein (RNP)-guided 2'-O-methylation of nucleotides C34 and U39 followed by intron excision. Positioning of the box C/D guide RNA within the intron of this pre-tRNA led to the assumption that nucleotide methylation is guided by the cis-positioned box C/D RNPs. We have now investigated the mechanism of 2'-O-methylation for t...

The main idea of this note is to show the most basic and purely mechanistic model of population growth, which has been used by us to create models of interspecific competition for verification of the competitive exclusion principle (1, 2). Our logical deterministic individual-based cellular automata model demonstrates a spatio-temporal mechanism of the S-shaped population growth. A classical mo...

Abstract—Circularly-polarized arrays of cavity backed slot (CBS) antennas are proposed for X-band satellite-earth communications. Two configurations of such circularly polarized arrays are investigated: cross-shaped and square-shaped arrays. Both configurations can produce right-hand circular polarization (RHCP) as well as lefthand circular polarization (LHCP) by proper setting of excitation ph...
