Semiconductor p-n junctions are essential building blocks for electronic and optoelectronic devices. In conventional p-n junctions, regions depleted of free charge carriers form on either side of the junction, generating built-in potentials associated with uncompensated dopant atoms. Carrier transport across the junction occurs by diffusion and drift(More)
Leaderless translation is prevalent in haloarchaea, with many of these leaderless transcripts possessing short 5'-untranslated regions (UTRs) less than 10 nucleotides. Whereas, little is known about the function of this very short 5'-UTR. Our previous studies determined that just four nucleotides preceded the start codon of hsp70 mRNA in Natrinema sp. J7,(More)

BACKGROUND Prediction of postoperative survival for hilar cholangiocarcinoma (HCCA) remains difficult although there have been a variety of clinical classification and staging systems. This study was designed to validate and compare some of the major HCCA staging systems in use today. In addition, we sought to build up a new staging system modified from(More)
Memory is very important in the present era of Internet of Thing (IoT) and Big Data, while Resistive Random Access Memory (RRAM) is a key member in the family of non-volatile memory. However, in the development of high density RRAM memory array, self-heat effect (SHE) as well as thermal crosstalk must be understood and controlled during its operation. In(More)
Electrothermal characterization of the advanced SOI FinFETs is performed in this paper, which is based on some analytical equations as well as in-house developed finite difference algorithm. The temperature-dependent properties of thermal conductivities of all materials involved are considered in our simulation, with results validated by the commercial(More)
Monolayer MoS<sub>2</sub> photodetectors are modeled and simulated by self-consistently solving diffusive transport equations in the presence of light illumination with the two-dimensional (2-D) Poisson equation. The simulated results indicate that very high photoresponsivity (PR) of ~1000A/W observed in others' experiments is due to strong electrostatic(More)
