Essential properties of multilayer graphenes are diversified by the number of layers and the stacking configurations. For an N-layer system, Landau levels are divided into N groups, with each identified by a dominant sublattice associated with the stacking configuration. We focus on the main characteristics of Landau levels, including the degeneracy, wave functions, quantum numbers, onset energies, field-dependent energy spectra, semiconductor-metal transitions, and crossing patterns, which are

... reflected in the magneto-optical spectroscopy, scanning tunneling spectroscopy, and quantum transport experiments. The Landau levels in AA-stacked graphene are responsible for multiple Dirac cones, while in AB-stacked graphene the Dirac properties depend on the number of graphene layers, and in ABC-stacked graphene the low-lying levels are related to surface states. The Landau-level mixing leads to anticrossings patterns in energy spectra, which are seen for intergroup Landau levels in AB-stacked graphene, while in particular, a formation of both intergroup and intragroup anticrossings is observed in ABC-stacked graphene. The aforementioned magneto-electronic properties lead to diverse optical spectra, plasma spectra, and transport properties when the stacking order and the number of layers are varied. The calculations are in agreement with optical and transport experiments, and novel features that have not yet been verified experimentally are presented.

Sporamin accounts for about 60% to 80% of total soluble protein in sweet potato tubers, and the predicted protein sequence of sporamin shares significant amino acid sequence identity with some Kunitz-type trypsin inhibitors. We constructed three recombinant plasmids with cDNAs that encode preprosporamin, prosporamin, and sporamin, and these three were expressed in Escherichia coli cells as fusion proteins. All three forms of sporamin expressed in E. coli were shown to have strong inhibitory

... vity to trypsin in vitro, suggesting that post-translational modifications are not essential for trypsin inhibitory activity. Northern blot analysis showed that sporamin transcripts could be systemically induced in leaf tissue of sweet potato by wounding. Therefore, sporamin may have a defense role as a protease inhibitor, in addition to its role as a storage protein.

Real-world natural language processing (NLP) models need to be continually updated to fix the prediction errors in out-of-distribution (OOD) data streams while overcoming catastrophic forgetting. However, existing continual learning (CL) problem setups cannot cover such a realistic and complex scenario. In response to this, we propose a new CL problem formulation dubbed continual model refinement (CMR). Compared to prior CL settings, CMR is more practical and introduces unique challenges

... ry-agnostic and non-stationary distribution shift, diverse mixtures of multiple OOD data clusters, error-centric streams, etc.). We extend several existing CL approaches to the CMR setting and evaluate them extensively. For benchmarking and analysis, we propose a general sampling algorithm to obtain dynamic OOD data streams with controllable non-stationarity, as well as a suite of metrics measuring various aspects of online performance. Our experiments and detailed analysis reveal the promise and challenges of the CMR problem, supporting that studying CMR in dynamic OOD streams can benefit the longevity of deployed NLP models in production.

BACKGROUND AND PURPOSE Appetite suppression induced by amphetamine has been attributed to its inhibition of neuropeptide Y (NPY) neurons and activation of pro-opiomelanocortin (POMC) neurons in the hypothalamus. This study examined whether STAT3 was involved in these actions of amphetamine. EXPERIMENTAL APPROACH Rats were given amphetamine daily for 4 days. Changes in the expression of NPY, POMC, melanocortin MC3 receptors, PI3K and STAT3 in the hypothalamus were assessed by RT-PCR and Western

... lotting. Antisense oligonucleotides to STAT3 were also used. KEY RESULTS Expression of NPY decreased with a maximum effect day 2 of amphetamine treatment. Expression of POMC, MC3 receptors, PI3K and STAT3 increased with a maximum response on day 2. Moreover, phosphorylation of STAT3 and its DNA binding activity increased and was expressed in a similar pattern. Infusion (i.c.v.) of STAT3 antisense at 60 min before amphetamine treatment, partly blocked amphetamine-induced anorexia and modulated expression of NPY, POMC, MC3 receptors and PI3K, indicating the involvement of STAT3 in amphetamine-treated rats. CONCLUSIONS AND IMPLICATIONS Hypothalamic PI3K-STAT3 signalling participated in the regulation of NPY-and POMC-mediated appetite suppression. These findings may contribute to a better understanding of anorectic drugs.

& Aims: Integrated hepatitis B virus (HBV) DNA, found in >85% of HBV-associated hepatocellular carcinomas (HBV-HCC), can play a significant role in HBV-related liver disease progression. HBV-host junction sequences (HBV-JS's), created through integration events, have been used to determine HBV-HCC clonality. Here, we investigate the feasibility of analyzing HBV integration in a noninvasive urine liquid biopsy. Approach & Results: Utilizing an HBV-targeted NGS assay, we first identified HBV-JS's

... in 8 HBV-HCC tissues and designed short-amplicon junction-specific PCR assays to detect HBV-JSs in matched urine. We detected and validated tissue-derived junctions in 5 of 8 matched urine samples. Next, we screened 32 urine samples collected from 25 HBV-infected patients (5 with hepatitis, 10 with cirrhosis, 4 with HCC, and 6 post-HCC). Encouragingly, all 32 urine samples contained HBV-JS's detectable by HBV-targeted NGS. Of the 712 total HBV-JS's detected in urine, 351 were in gene-coding regions, 11 of which, including TERT, had previously been reported as recurrent integration sites in HCC tissue and were found in urine of cirrhosis or HCC patients only. The integration breakpoints of HBV DNA detected in urine were found predominantly (~70%) at a previously identified integration hotspot, HBV DR1-2. Conclusions: HBV viral-host junction DNA can be detected in urine of HBV-infected patients. This study is the first study to demonstrate the potential for a noninvasive urine liquid biopsy of integrated HBV DNA to monitor HBV-infected patients for HBV-associated liver diseases and the efficacy of antiviral therapy.

Titanium nitride (TiN) and superconducting YBa 2 Cu 3 O 7 (YBCO) thin films have been deposited sequentially on SrTiO 3 (STO)(100) substrates by in situ pulsed laser ablation. The TiN films were originally intended to serve as the lower contact electrode of the c-axis YBCO thin films. It was found that, although high-quality YBCO films could be obtained with the YBCO/TiN/STO(100) bilayer structure, the TiN(100) layer was oxidized which changed the structure into YBCO/TiO 2 /STO(100) during YBCO

Comparative studies of depositing YBCO films directly onto a dc-sputtered TiO 2 /STO(100) template conventionally used in the selective epitaxial growth (SEG) process have, however, resulted in formation of a nonsuperconducting YBCO top layer. The characteristics of the resultant TiO 2 layers obtained using various processes were analyzed to delineate the apparent discrepancies.

Many students exhibit fear of speaking in English in the English as Second Language (ESL) classrooms. Additionally, there are limited studies in this area of concern among the undergraduates in Sarawak. Hence, this study aimed to identify the students" anxiety level towards speaking English based on four components, namely communication apprehension, test anxiety, fear of negative evaluation, and comfort in using English in the classrooms. This study also examined whether there is any

... t difference in the level of anxiety in terms of gender. A total of 592 undergraduates from two public institutions of higher learning in Sarawakwere involved in this study. A Public Speaking Class Anxiety Scale (PSCAS) by Yaikhong and Usaha (2012) was adopted in this study to measure anxiety in the ESL speaking classes. The results gathered through the questionnaires were analysed using SPSS package to determine the students" speaking anxiety levels and the significant difference in the level of anxiety in speaking English in terms of gender. The findings revealed that undergraduates experienced an average level of speaking anxiety. T-test analysis of the findings in the study also portrayed that generally the female undergraduates experienced higher speaking anxiety as compared to the male undergraduates in all the four factors of ESL speaking anxiety. Among the four factors of speaking anxiety, only the factor of 'comfort in using English' in the classrooms showed a statistically significant difference between male and female undergraduates. Findings of this study would be significant as knowing the level of anxiety among the undergraduates in ESL classrooms will provide the basis for educators to plan better strategies or techniques to help students in overcoming their English speaking anxiety and to improve their oral English proficiency. It will also help students to be aware of their own speaking anxiety level so that they can seek for measures to overcome their speaking anxiety.
