The coupling between electrical, thermal, and spin transport results in a plethora of novel phenomena. However, disentangling different effects is experimentally very challenging. We demonstrate that bilayers consisting the antiferromagnetic insulator hematite ($\ensuremath{\alpha}\text{\ensuremath{-}}{\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$) Pt allow one to precisely measure transverse Nernst magnet...
Multiple loci have been associated with either primary open angle glaucoma (POAG) or heritable ocular quantitative traits associated with this condition. This study examined the association of these loci with POAG, with central corneal thickness (CCT), vertical cup-to-disc ratio (VCDR) and with diabetes mellitus in a group of black South Africans (215 POAG cases and 214 controls). The populatio...
در این پایان نامه به مطالعه یک مسئله مربوط به طراحی شبکه های بی سیم با استفاده از آنتن های جهت دار پرداخته می شود. مسئله را به صورت مجموعه p از n نقطه در صفحه، هر یک متناظر با یک فرستنده و گیرنده مجهز به یک آنتن جهت دار با زاویه آلفا و شعاع r مدل می کنیم. نشان داده می شود که اگر $alpha = pi /3$ باشد آن گاه همیشه جهت یابی از آنتن های جهت دار با زاویه $alpha $ امکان پذیر است به طوری که گراف ارتبا...
در این پایان نامه, یک روش تحلیلی عددی برای حل معادله دیفرانسیل جزئی خطی و غیرخطی از مرتبه کسری بفرم $ _{t_{0}}^{c} d_{t}^{alpha}u(x,t)=f(x,t,u(x,t)) $ با شرط اولیه $ u(x,0)=f(x) $ را بررسی می کنیم که در آن _{t_{0}}^{c}d_{t}^{alpha} مشتق از مرتبه کسری از نوع مشتق کاپوتو و $ 0<alphaleq 1 $ می باشد. در این کار, روش تبدیل دیفرانسیل تعمیم یافته (gdtm) ر...
OBJECTIVE To investigate whether polymorphisms in the estrogen receptor alpha (ESR1) and beta (ESR2) genes were a risk factor for open-angle glaucoma (OAG). METHODS Participants 55 years and older from the population-based Rotterdam Study underwent, at baseline and at follow-up, the same ophthalmic examination, including visual field screening and stereo optic disc photography. A diagnosis of...
We investigate the shadow, deflection angle, and greybody bounding of a Schwarzschild-AdS/dS black hole in scale-dependent gravity. used EHT data to constrain parameter $\epsilon$. have found that within $1\sigma$ level uncertainty, $\epsilon M_0$ ranges at $10^{-11} - 10^{-16}$ orders magnitude for Sgr. A*, 10^{-17}$ M87*. Using these parameters, we explored how shadow radius behaves as percei...
BACKGROUND There are currently no studies that have examined the recurrence of the cam lesion after femoral neck osteoplasty for femoroacetabular impingement. Although patient-reported outcome (PRO) scores at midterm follow-up have shown continued success, the maintenance of a normalized alpha angle has not been shown radiographically. PURPOSE To assess the radiographic recurrence of cam defo...
We report a novel correlated background in the antineutrino detection using inverse beta decay reaction. Spontaneous fissions and $(\ensuremath{\alpha},n)$ reactions peripheral materials of detector, such as borosilicate glass photomultipliers, produce fast neutrons prompt gamma rays. If shielding from material to detector target is not thick enough, gammas could enter volume mimic signals. Thi...
BACKGROUND Our purpose was to evaluate outcome following arthroscopic treatment of femoroacetabular impingement (FAI) in middle-aged patients and to define risk factors for conversion to total hip arthroplasty (THA). METHODS This was a retrospective case series of 79 consecutive patients (40 to 65 years) undergoing arthroscopic treatment of FAI (follow-up ≥12 months). Outcome at follow-up was...
A consensus classification and nomenclature are defined for RNA backbone structure using all of the backbone torsion angles. By a consensus of several independent analysis methods, 46 discrete conformers are identified as suitably clustered in a quality-filtered, multidimensional dihedral angle distribution. Most of these conformers represent identifiable features or roles within RNA structures...
