We propose an all-orders βeta function for current-current interactions in 2d with flavor anisotropy. When the number of left-moving and right-moving flavors are unequal, the βeta function has a non-trivial fixed point at finite values of the couplings. We also extend the computation to simple cases with both flavor and color anisotropy. Typeset using REVTEX
The recently proposed all orders βeta function is further investigated. By using a strong-weak coupling duality of the βeta function, and some added topology of the space of couplings we are able to extend the flows to arbitrarily large or small scales. Using a non-trivial RG invariant we are able to identify sine-Gordon, sinh-Gordon and Kosterlitz-Thouless phases. We also find an additional ph...

Introduction: One of the most important goals of universities across the world is to train entrepreneur graduates. Therefore, special attention should be given to variables that can affect entrepreneurial characteristics. The aim of this study was to examine the correlation of critical thinking disposition and achievement goal orientation with student entrepreneurial characteristics. Methods: T...
Sempatik sinirlerin insan vücudunda çeşitli etkilere yol açtığı 19.yüzyıldan itibaren bilinmektedir. Birden fazla adrenerjik reseptör olduğu Ahlquist tarafından ilk olarak 1948 yılında ileri sürülmüş ve birçok araştırıcı bu reseptörlerin sayısının bilinmediği ifade edilmiştir. Daha sonra 1984 Arch adlı bilim adamı kemirgenlerde beyaz kahverengi yağda atipik bir β adrenoseptor (AR) varlığı ortay...
measurement of serum creatinine (cr) and blood urea nitrogen (bun) are used as indicators of glomerular filtration rate. the increased levels of these biomarkers are usually detectable at advanced stages of kidney complications. the aim of this study was to find the interrelationship of beta-2 microglobulin (β2m), bun and cr in streptozotocin (stz)-induced diabetes mellitus in rabbits. diabetes...
Βeta-lactamase production is the most common mechanism of resistance in Gram-negative bacteria[2] which are also the most common etiological agents in UTI. Extended spectrum betalactamases(ESBLs) and AmpC beta-lactamasesare produced by many Enterobacteriaceae. ‘Plasmids’ carrying ESBL and AmpC genes often carry multiple other resistance genes, thus leading to multi drug resistance in clinical i...
