The 2D semimetallic electrodes have been employed to show outstanding contact properties with semiconducting transition‐metal dichalcogenides (TMDCs) channel, leading large enhancement of transistor and phototransistor performance. Herein, an innovative concept is established for a unique electrode‐2D TMDC channel (2D–2D) device configuration where the electronic structures are systematically m...

Abstract Energy efficiency and privacy preserving have become essential for the wireless sensor networks. In this paper, a joint energy time resource allocation problem cognitive users (CUs) in non-selfish symbiotic relaying scheme (NSCRS) is considered. We aim to maximize total (EE) of primary user CUs with consideration information under constraints CUs. With full channel state (CSI), an opti...

Background The assessment of right ventricular function is of great importance in the management of patients with pulmonary hypertension (PH). Our aim is to compare the value of cardiac MRI (CMRI), ultrasonic cardiogram (CUS), multidetector CT (MDCT) in assessing right ventricular function, and to evaluate the correlation between parameters derived by MRI, CUS, MDCT and the indicators of right ...

A facile one-pot solvothermal route using the reaction of sputtered copper film and sulfur powder in ethanol solution at a low temperature of 90 °C for 12 hours has been implemented to in situ synthesize 2D hexagonal copper sulfide (CuS) nanoflakes. Their field electron emission (FE) characteristics were investigated and were found to have a close relationship with the copper film's thickness. ...

CuS-graphene nanosheet (GNS) composites with well-defined morphology have been successfully fabricated via a simple one-pot hydrothermal route by using thioacetamide (TAA) as both the sulfur source and reducing agent. The as-prepared CuS-GNS composites with an appropriate content of graphene exhibited an even higher peroxidase-like catalytic activity than pristine CuS nanoparticles in acetate b...

which caused severe soft tissue infection after ? shbone injury, emerged in Israel. We conducted a follow-up study from 1998 through 2005 to assess changing trends, outcomes, and molecular relatedness of the implicated strains. A total of 132 cases (71% con? rmed and 29% suspected) of V. vulnifi cus biotype 3 infection were found. Most infections (95%) were related to percutaneous ? sh exposure...

Lipodermatosclerosis and diabetic dermopathy are low-risk skin lesions with many similar clinical features, except for venous abnormalities such as chronic venous insufficiency, but are rarely a reason for referring the patient to vascular ultrasound examination. We present 3 serial cases in which the compression ultrasound examination (CUS) of the venous circulation of the affected limbs was o...

This paper considers a resource allocation problem in device-to-device (D2D) communications sharing the same frequency spectrum. In particular, cellular users (CUs) utilize non-orthogonal multiple access (NOMA) while D2D (DUs) adopt orthogonal division (OFDMA). A multi-objective optimization (MOOP) is formulated, which jointly maximizes sum rate of DUs and CUs uplink taking into account maximum...
