Let Γ be a principal congruence subgroup of SLn(Z) and let σ be an irreducible unitary representation of SO(n). Let N cus(λ, σ) be the counting function of the eigenvalues of the Casimir operator acting in the space of cusp forms for Γ which transform under SO(n) according to σ. In this paper we prove that the counting function N cus(λ, σ) satisfies Weyl’s law. Especially, this implies that the...
Link adaptation is an important issue in the design of cognitive radio networks, which aims at making efficient use of system resources. In this paper, we propose and investigate a joint adaptive modulation and power allocation algorithm in cognitive radio networks. Specifically, the modulation scheme and transmit power are adjusted adaptively according to channel conditions, interference limit...

Abstract Chronic stress is thought to impart risk for depression via alterations in brain 18 structure and function, but contributions of specific mediators in generating these changes 19 remain unclear. We test the hypot...
BACKGROUND AND OBJECTIVE Diagnosis of acute deep vein thrombosis (DVT) and of pulmonary embolism (PE) is often difficult: symptomatic patients are usually investigated employing several diagnostic tests, which should be appropriately selected and sequenced, taking into account their sensitivity, specificity, safety and cost. The objective of this paper is to evaluate the performance of the new ...
In this letter, a underlay cognitive radio inspired non-orthogonal multiple access (CR-NOMA) network assisted by the reconfigurable intelligent surface (RIS) technique is conceived to maximize energy efficiency (EE), while all users (CUs) are located in “dead zone”. particular, CUs could only receive information from base station (CBS) via RIS. The EE maximization optimization problem which non...
We construct the cell-centered Finite Volume discretization of the twodimensional inviscid primitive equations in a domain with topography. To compute the numerical fluxes, the so-called Upwind Scheme (US) and the Central-Upwind Scheme (CUS) are introduced. For the time discretization, we use the classical 4th order RungeKutta method. We verify, with our numerical simulations, that the US (or C...
Recently, mitochondria-targeted photothermal nanoagents demonstrated an improved therapeutic efficacy of cancer cells, compared with non-targeting ones. Herein, copper sulfide (CuS) nanoparticles are in situ synthesized via bovine serum albumin (BSA) templates to prepare BSA@CuS nanocomposites high efficiency (42.0%) conversion. Subsequently, rhodamine-110 (R) molecules covalently conjugated co...
The mycotoxin ochratoxin A (OTA) is a secondary metabolite derived from multiple Aspergillus and Penicillium strains. development of rapid, sensitive, simple method for OTA detection important to ensure food biosafety safeguard public health. In this study, we designed highly specific sensitive assay the using copper monosulfide (CuS) nanoparticles conjugated an anti-OTA antibody (CuS-Ab NPs) f...
A large body of evidence supports the protective role flavonol antioxidant compound quercetin in mammals. We tested hypothesis that can protect against hypothalamus-pituitary-gonadal (HPG) axis defect like a reduction gonadotropins and testicular hormones abnormal semen analysis induced by chronic unpredictable stress (CUS), possibly via downregulation oxidative (ROS) p53-Bax-caspase-3 pathways...
در این کار پژوهشی، ترکیبات Ni50Al50 و Ni25Cr25Al50 (at%) مورد آلیاژسازی مکانیکی قرار گرفتند. تغییرات ساختاری ذرات پودر در طول آلیاژسازی مکانیکی به وسیله ی آزمون پراش پرتو ایکس (XRD) بررسی گردید. نتایج حاکی از تشکیل ترکیب بین فلزی نانوکریستال NiAl منظم از ترکیب Ni50Al50 پس از آلیاژسازی مکانیکی و ترکیب بین فلزی نانوکریستال NiCr)Al) از ترکیبNi25Cr25Al50 پس از آلیاژسازی مکانیکی و عملیات حرارتی بود....
