Inspired by the recent achievements of two-dimensional (2D) sub-5 nm MoS2 field effect transistors (FETs), we use ab initio quantum-transport methods to simulate transport properties gate-length monolayer (ML) MOSFETs. We find that ML double-gated MOSFETs (DGFETs) with 1, 3, and 5 gate length fail meet on-state current requirements in International Technology Roadmap for Semiconductors (ITRS) high-performance (HP) devices. However, both n- p-DGFETs can address ITRS low-power (LP)...
In the field of electromagnetic wave (EMW) absorption, development nonmagnetic materials with strong absorptive performance, low filling ratio, and wide bandwidth is significant importance. this work, five morphologies In2O3 nanomaterials are prepared by simple hydrothermal annealing processes. The products (including lamellar flower-, lychee-, cheese-, nanocube-, urchin-like In2O3) obtained using different surfactants. experimental results indicate that flower-like has a minimum reflection...
Zinc‐modified cobalt‐based metal–organic frameworks (ZCM) can effectively generate abundant reactive oxygen species to heal bacterially infected wounds. However, their instability under physiological conditions not only weakens its catalytic function but also leads the accumulation of large amounts metal ions, thereby increasing possibility new wound infections. In this study, synergistic antibacterial nanoparticles (ZCMCC) are synthesized by loading chlorogenic acid (CGA) on ZCM with...
Let be a higher-order recursive sequence. Several identities are obtained for the infinite sums and finite of reciprocals sequences. MSC:11B39.
We use the combinatorial method and algebraic manipulations to obtain several interesting identities involving power sums of derivative first kind Chebyshev polynomials. This solved an open problem proposed by Li (2015).
The main purpose of this paper is, using the properties Gauss sums and mean value theorem Dirichlet L-functions, to study a hybrid problem involving certain Hardy Kloosterman give two exact computational formulae for them. MSC:11L05, 11M20.
Abstract Background Juvenile Idiopathic Arthritis (JIA) is a condition that occurs when individuals under the age of 16 develop arthritis lasts for more than six weeks, and cause unknown. The development JIA may be linked to serum metabolites. Nevertheless, association between pathogenesis metabolites unclear, there are discrepancies in findings across studies. Methods In this research, humans 486 was assessed using genetic variation data genome-wide study. identification causal...
Bidirectional Mendelian randomization (MR) combined with clinical case analysis was used to elucidate the relationship between generalized anxiety disorder (GAD) caused by mental overload and risk of weight-bearing joint (hip/knee) osteoarthritis (OA).
The Fibonacci sequence has been generalized in many ways. One of them is defined by the relation if n even, odd, with initial values and , where a b are positive integers. In this paper, we consider reciprocal sum then establish some identities relating to denotes nearest integer x. MSC:11B39.

Background The purpose of this study was to determine whether high BMI affect short-term clinical and radiologic outcomes robotic-assisted total knee arthroplasty (TKA) by comparing the outcomes, complications between normal patients. Methods We retrospectively compared radiological 424 knees (408 patients). patients were divided into four groups: < 24.9 kg/m 2 (normal); 25.0 29.9 (overweight); 30.0 34.9 (obese class I) 35.0 39.9 II). Clinical evaluated. Results There no significant...
Nowadays, the immature p-GaN processes cannot meet manufacturing requirements of GaN impact ionization avalanche transit time (IMPATT) diodes. Against this backdrop, performance wide-bandgap p-SiC/n-GaN heterojunction double-drift region (DDR) IMPATT diode is investigated in paper for first time. The direct-current (DC) steady-state, small-signal and large-signal characteristics are numerically simulated. results show that compared with conventional single-drift (SDR) diode, DDR proposed...

Two-dimensional germanium is considered a promising new channel material to replace silicon owing its lower effective mass and larger electron–hole mobility. To investigate the transport characteristics of single-layer germanane transistors with gate lengths (Lg) below 5 nm, we utilize an ab initio quantum methodology. It was found that n-type having Lg 3 nm satisfy International Technology Roadmap for Semiconductors (ITRS) requirements on-state current (Ion), delay time, power-delay...
Abstract Rheumatoid arthritis (RA) patients undergoing total knee arthroplasty (TKA) face infection risk. The study evaluates vancomycin-loaded calcium sulfate bone as prevention. Patients with RA treated TKA who had their femoral canal filled using either (experimental group [n = 35]) or the patient's own excised autologous (control 30]) at Qingdao University Affiliated Hospital, Qingdao, China from January 1, 2017, to March 2023, were retrospectively enrolled in this study. An experienced...

Visual attention prediction is linked to brain activity, cognition, and behavior. Despite the availability of activity features, previous studies have not fully utilized them, resulting in saliency maps predicted by models primarily based on image features that do accurately reflect visual human brain. This inspires us use functional Magnetic Resonance Imaging (fMRI) signals as a "brain observer" supervise training developing integrate top-down attention-dependent cues information from...
