Design of High Performance Si/SiGe Heterojunction Tunneling FETs with a T-Shaped Gate

In this paper, a new Si/SiGe heterojunction tunneling field-effect transistor with a T-shaped gate (HTG-TFET) is proposed and investigated by Silvaco-Atlas simulation. The two source regions of the HTG-TFET are placed on both sides of the gate to increase the tunneling area. The T-shaped gate is designed to overlap with N+ pockets in both the lateral and vertical directions, which ...

Heterologous expression and characterization of a 3-ketosteroid-∆1-dehydrogenase from Gordonia neofelifaecis and its utilization in the bioconversion of androst-4,9(11)-dien-3,17-dione

3-Ketosteroid-∆1-dehydrogenase (KstD), a key enzyme in microbial steroid catabolism, catalyzes the trans-axial elimination of the C1 and C2 hydrogen atoms of the A-ring from the polycyclic ring structure of 3-ketosteroids, and it was usually used to transform androst-4-ene-3,17-dione (AD) to produce androsta-1,4-diene-3,17-dione. Here, the KstD from Gordonia neofelifaecis was ...

BPS spectrum on AdS3×S3×S3×S1

The BPS spectrum of string theory on AdS3 × S3 × S3 × S1 is determined using a world-sheet description in terms of WZW models. It is found that the theory only has BPS states with j + = j − where j ± refer to the spins of the \( \mathfrak{s}\mathfrak{u}(2) \) algebras of the large \( \mathcal{N} \) = 4 superconformal algebra. We then re-examine the BPS spectrum of the corresponding ...

Forced oscillation for solutions of boundary value problems of fractional partial difference equations

In this paper, we obtain the forced oscillation of solutions for certain fractional partial difference equations with two different types of boundary conditions. Our results are based on discrete Gaussian formula and some basic theories of discrete fractional calculus. MSC: 26A33, 39A21, 39A14, 39A12.

Applications of the generalised Dirichlet integral inequality to the Neumann problem with fast-growing continuous data

By using the generalised Dirichlet integral inequality with continuous functions on the boundary of the upper half-space, we prove new types of solutions for the Neumann problem with fast-growing continuous data on the boundary. Given any harmonic function with its negative part satisfying similarly fast-growing conditions, we obtain weaker boundary integral condition.

Oscillation results for certain forced fractional difference equations with damping term

In this paper, we establish two sufficient conditions for the oscillation of forced fractional difference equations with damping term of the form ( 1 + p ( t ) ) Δ ( Δ α x ( t ) ) + p ( t ) Δ α x ( t ) + f ( t , x ( t ) ) = g ( t ) , t ∈ N 0 , with initial condition Δ α − 1 x ( t ) | t = 0 = x 0 , where 0 < α < 1 is a constant, Δ α x is the Riemann-Liouville fractional difference ...

Using WeChat official accounts to improve malaria health literacy among Chinese expatriates in Niger: an intervention study

Background Malaria is the main health risk for Chinese expatriates working in Niger. Health education is a recommended intervention for prevention of malaria among non-immune travellers and expatriate workers. It is urgent to develop an effective and feasible way for these populations to obtain information about the prevention and treatment of malaria. Methods An individually ...

Oscillation of solutions for certain fractional partial differential equations

In this paper, sufficient conditions are established for the forced oscillation of fractional partial differential equations of the form ∂ ∂ t ( D + , t α u ( x , t ) ) = a ( t ) Δ u ( x , t ) − m ( x , t , u ( x , t ) ) + f ( x , t ) , ( x , t ) ∈ Ω × R + ≡ G , with one of the two following boundary conditions: ∂ u ( x , t ) ∂ N = ψ ( x , t ) , ( x , t ) ∈ ∂ Ω × R + , or u ( x , t ...

Turing learning: a metric-free approach to inferring behavior and its application to swarms

We propose Turing Learning, a novel system identification method for inferring the behavior of natural or artificial systems. Turing Learning simultaneously optimizes two populations of computer programs, one representing models of the behavior of the system under investigation, and the other representing classifiers. By observing the behavior of the system as well as the behaviors ...

Epileptic seizure, as the first symptom of hypoparathyroidism in children, does not require antiepileptic drugs

Objective Patients with hypoparathyroidism exhibit metabolic disorders (hypocalcemia) and brain structural abnormalities (brain calcifications). Currently, studies have determined whether antiepileptic drug (AED) treatment is required for epileptic seizures in children with hypoparathyroidism. Method This study aims to evaluate the data of two medical centers in Beijing based on ...

Syphilitic aortic aneurysm with a pulmonary lesion: a case report and literature view

Introduction Syphilitic aortic aneurysm (SAA) is caused by tertiary stage of syphilis infection. As the wide application of penicillin, this complication is becoming rarer than before. The SAA with lung cancer is a very rare disease in patient. Case description A 55-year-old male was admitted to the hospital complaining “progressive hoarseness for 3 months” and the patient has been ...

Presence of zoonotic Cryptosporidium scrofarum, Giardia duodenalis assemblage A and Enterocytozoon bieneusi genotypes in captive Eurasian wild boars (Sus scrofa) in China: potential for zoonotic transmission

Background Cryptosporidium spp., Giardia duodenalis and Enterocytozoon bieneusi are the main causal pathogens of gastrointestinal disease. However, there are limited reports about the prevalence of these organisms in captive Eurasian wild boars worldwide. Therefore, we examined the occurrence and identified the species/assemblages/genotypes of these pathogens in captive Eurasian ...

Hepatitis E Virus Genotype 4 Sequences Detected in Sewage from Treatment Plants of China

The aim of this study was to investigate the occurrence of hepatitis E virus (HEV) in sewage samples in Shen Zhen, China. Sewage samples were collected from 152 sewage plants including livestock sewage, domestic sewage and treated sewage from May to July of 2015. Two of 152 samples were HEV positive (1.32%) from the livestock sewage plants. Partial ORF2 fragments of HEV were ...

Twisted sectors from plane partitions

Twisted sectors arise naturally in the bosonic higher spin CFTs at their free points, as well as in the associated symmetric orbifolds. We identify the coset representations of the twisted sector states using the description of \( {\mathcal{W}}_{\infty } \) representations in terms of plane partitions. We confirm these proposals by a microscopic null-vector analysis, and by ...
