Beyond the spontaneous chiral symmetry breaking scale light and strange baryons should be considered as systems of three constituent quarks with an effective confining interaction and a flavor-spin chiral interaction that is mediated by the octet of Goldstone bosons (pseudoscalar mesons) between the constituent quarks. One cannot exclude, however, the possibility that this flavor-spin interacti...

We consider Boolean dynamics for biological networks where stochasticity is introduced through asynchronous updates. An exact method is given for finding states which can reach a steady state with positive probability, and a method is given for finding states which cannot reach other steady states. The methods are based on computational commutative algebra. The algorithms are applied to dynamic...

We have performed a Discrete Fourier Transform on 136 CCD B, V and R frames of the Z Cam–type dwarf nova V1101 Aql. Our analysis indicates as possible orbital period Porb = 3 .46, though we cannot exclude the alias at 4.00. We estimate the distance to the system to be about 300 pc. We possibly discovered a bright bow–shaped nebulosity around the object.

The existence of extra chiral generations is strongly disfavored by the precision electroweak data if all the extra fermions are heavier than mZ . However fits as good as the SM can be obtained if one allows the new neutral leptons to have masses close to 50 GeV. In the framework of SUSY models precision measurements cannot exclude one additional generation of heavy fermions if chargino and neu...

A precise formulation for the relations among certain variables under a set of polynomial equations and a set of polynomial inequations (to exclude certain special cases which cannot be excluded by the selection of parameters alone) is given. Several methods are presented to find such relations. The methods have been implemented and used to find geometry formulas, to discover geometry theorems,...

Our objective is to investigate scattering from the sea surface that seemingly cannot be explained using composite surface models based on Bragg scattering theory. Models based on Bragg scattering adequately predict most backscatter observations, but several phenomena are not well predicted using this type of approach, suggesting the models exclude some relevant physical processes. This researc...

Certain doxastic paradoxes (paradoxes analogous to the Paradox of the Liar but involving ideal belief instead of truth) demonstrate that some formal paradoxes cannot be avoided simply by limiting the expressiveness of one's formal language in order to exclude the very possibility of self-referential thoughts and beliefs. These non-selfreferential paradoxes, moreover, should be of special intere...

Bombay Ophthalmic ajDpointment give his opinion that, whatever we do, we cannot altogether exclude suppuration in cataract work A definite responsibility for infective losses must be faced."?Colonel Herbert, Indian Medical Gazette, January 1917. " With me suppurations are too frequent. There is a standing reward of Rs. 10 for a hundred consecutive cases without a suppuration. This goes to the d...

Putative fossil embryos and larvae from the Precambrian phosphorite rocks of the Doushantuo Formation in Southwest China have been examined in thin section by bright field and polarized light microscopy. Although we cannot completely exclude a nonbiological or nonmetazoan origin, we identified what appear to be modern cnidarian developmental stages, including both anthozoan planula larvae and h...
