The nonperturbative aspects of string theory are explored for noncritical string in two distinct formulations, loop equations and matrix models. The effects corresponding to the D-brane in these formulations are especially investigated in detail. It is shown that matrix models can universally yield a definite value of the chemical potential for an instanton while loop equations cannot. This imp...

Osteoradionecrosis (ORN) is a serious complication of radiation therapy, which was first described by Ewing in 1926.(1) While ORN of the mandible has been commonly reported, any radiated bone has potential to be effected. While ORN of the temporal bone is a relatively rare and indolent disorder, it can have devastating sequelae. It typically presents with chronic otomastoiditis. This is, to the...

Electrical properties of Nano TiO2 coatings as a function the nanoparticle size have been studied. In addition, this study explores how to calculate quantum confinement energy TiO2. The results confirm effect particle on electrical especially when becomes close exciton Bohr radius. are not effected 40 nm. radius has found be 1.4 While was 0.43 eV. program depends Characteristic Matrix Theory an...

The further provided more updates and a comprehensive understanding recent trends how it adversely affected Mogadishu. 50 participated study result has showed that had negatively impacted performance businesses. caused to delay payments liabilities, disrupted its supply, sales debt incre...

Abstract Introduction With this pilot study, authors aimed to find how OSA and insomnias (sleep onset maintenance insomnia) interact. Methods Data from PSG-level 1 consecutive Obstructive Sleep Apnea (OSA) patients were retrospectively collected. Insomnia severity assessed. Arousals (A), arousal index (AI), wakefulness after sleep (WASO), total time (TST) eficiency (SE) used better characterize...

Dnmt2/Trdmt1 is a methyltransferase, which has been shown to methylate tRNAs. Deficient mutants were reported to exhibit various, seemingly unrelated, defects in development and RNA-mediated epigenetic heredity. Here we report a role in a distinct developmental regulation effected by a noncoding RNA. We show that Dnmt2-deficiency in mice results in cardiac hypertrophy. Echocardiographic measure...

The skeleton of an adult male, dating to the Early Iron Age of the Assyrian Period (B.C. 8th7th cc), recovered in South Eastern Turkey was analyzed. It reveals significant biological and cultural deformations. This so-called Zeviya Tivilki individual represents the first known record of circular-type double bandage artificial cranial deformation from the Iron Age in Anatolia. The presence of cr...
