Magneto-transport properties of monolayer borophene in perpendicular magnetic field: influence of electron-phonon interaction

The magneto-transport properties of a borophene monolayer in a perpendicular magnetic field B are studied via calculating the conductivity tensor and resistance under electron-optical phonon interaction by using the linear response theory. Numerical results are obtained and discussed for some specific parameters. The magnetic field-dependent longitudinal conductivity shows the magneto-phonon resonance effect that describes the transition of electrons between Landau levels by absorbing/emitting an optical phonon. The Hall conductivity increases first and then decreases with the magnetic field strength. Also, the longitudinal resistance increases significantly with increasing temperature, which shows the metal behaviour of the material. Practically, the observed magneto-phonon resonance can be applied to experimentally determine some material parameters, such as the distance between Landau levels and the optical phonon energy

Course design and development: Focus on student learning experience

Learning is not an outcome and, as a process, is more than just taking classes. It is a transformation journey a student walks through, and experiences picked up along the journey contribute gradually to student competence development. Competence, what companies are looking for from graduates, cannot be handed directly and will not be built unless the learning process is properly designed, developed and executed. This research work aims to present a process for course design and development, focused on embedding learning experience into a course. Bloom's Taxonomy is utilized for identifying learning outcomes. Kolb's Experiential Learning Cycle is introduced for planning learning activities for ease of learning. Last, but not least, a recently developed LOVE model is applied for the selection of teaching and learning methods for offering a diversified learning experience. An existing project-based learning engineering postgraduate course on Product Design and Development is assessed to illustrate the proposed process for course design and development.This work is the outcome of project “Curriculum Development of Master’s Degree Program in Industrial Engineering for Thailand Sustainable Smart Industry (MSIE 4.0)” that has been funded with support from the European Commission (Project Number: 586137-EPP-1-2017-1-TH-EPPKA2-CBHE-JP).

Roles of MSIE graduates to support Thailand sustainable smart industry

The way business run has changed in recent decades due to technology advancement, and it has become more explicit in many parts of the world that companies have been moving from stand-alone technology exploitation towards holistically integrated technology exploitation. Thailand's government has also foreseen the need for change from a production-based economy to a value-based economy and has encouraged the Thai industry to focus more on producing innovative products and services which require high potential and skilled knowledge workers. Consequently, their roles will never be the same. This paper presents findings on the expected roles of graduates with a Master degree in Industrial Engineering (MSIE) drawn from an industry survey on industry needs to attain Industry 4.0 conducted with companies based in Thailand and in three European countries participating in Erasmus+ Capacity Building in Higher Education project on Curriculum Development of Master’s Degree Program in Industrial Engineering for Thailand Sustainable Smart Industry (MSIE 4.0). From the survey results, top-three technologies for being competitive and areas of applications to attain industry 4.0 in the companies' perspective were identified. Roles of MSIE graduates were determined for individual potential applications generated from identified technology-application relationships. According to the findings, the graduates are expected in general to play an important role in effective utilization of big data and real-time data for better decision making on various industrial practical problems as well as for better responsiveness to customers. The same procedure can be applied in other disciplines for identifying the roles of their graduates.This work is the outcome of project “Curriculum Development of Master’s Degree Program in Industrial Engineering for Thailand Sustainable Smart Industry (MSIE 4.0)” that has been funded with support from the European Commission (Project Number: 586137-EPP-1-2017-1-TH-EPPKA2-CBHE-JP).

Molecular Characterization of HIV-1 CRF01_AE in Mekong Delta, Vietnam, and Impact of T-Cell Epitope Mutations on HLA Recognition (ANRS 12159)

To date, 11 HIV-1 subtypes and 48 circulating recombinant forms have been described worldwide. The underlying reason why their distribution is so heterogeneous is not clear. Host genetic factors could partly explain this distribution. The aim of this study was to describe HIV-1 strains circulating in an unexplored area of Mekong Delta, Vietnam, and to assess the impact of optimal epitope mutations on HLA binding.We recruited 125 chronically antiretroviral-naive HIV-1-infected subjects from five cities in the Mekong Delta. We performed high-resolution DNA typing of HLA class I alleles, sequencing of Gag and RT-Prot genes and phylogenetic analysis of the strains. Epitope mutations were analyzed in patients bearing the HLA allele restricting the studied epitope. Optimal wild-type epitopes from the Los Alamos database were used as reference. T-cell epitope recognition was predicted using the immune epitope database tool according to three different scores involved in antigen processing (TAP and proteasome scores) and HLA binding (MHC score). with a Vietnamese specificity held by two different haplotypes. The percentage of homology between Mekong and B consensus HIV-1 sequences was above 85%. Divergent epitopes had TAP and proteasome scores comparable with wild-type epitopes. MHC scores were significantly lower in divergent epitopes with a mean of 2.4 (±0.9) versus 2 (±0.7) in non-divergent ones (p<0.0001).Our study confirms the wide predominance of CRF01_AE in the Mekong Delta where patients harbor a specific HLA pattern. Moreover, it demonstrates the lower MHC binding affinity among divergent epitopes. This weak immune pressure combined with a narrow genetic diversity favors immune escape and could explain why CRF01_AE is still predominant in Vietnam, particularly in the Mekong area

Comparative Genomics of the \u3ci\u3eCampylobacter lari\u3c/i\u3e Group

The Campylobacter lari group is a phylogenetic clade within the epsilon subdivision of the Proteobacteria and is part of the thermotolerant Campylobacter spp., a division within the genus that includes the human pathogen Campylobacter jejuni. The C. lari group is currently composed of five species (C. lari, Campylobacter insulaenigrae, Campylobacter volucris, Campylobacter subantarcticus, and Campylobacter peloridis), as well as a group of strains termed the urease-positive thermophilic Campylobacter (UPTC) and other C. lari-like strains.Herewepresent the complete genomesequences of 11 C. lari group strains, including the five C. lari group species, four UPTC strains, and a lari-like strain isolated in this study. The genome of C. lari subsp. lari strain RM2100 was described previously. Analysis of the C. lari group genomes indicates that this group is highly related at the genome level. Furthermore, these genomes are strongly syntenic withminor rearrangements occurringonly in 4 of the12 genomes studied. The C. lari group can be bifurcated, based on the flagella and flagellar modification genes.Genomic analysis of the UPTC strains indicated that these organisms are variable but highly similar, closely related to but distinct from C. lari. Additionally, the C. lari group contains multiple genes encoding hemagglutination domain proteins, which are either contingency genes or linked to conserved contingency genes. Many of the features identified in strain RM2100, such as major deficiencies in amino acid biosynthesis and energy metabolism, are conserved across all 12 genomes, suggesting that thesecommonfeatures may play a role in the association of the C. lari group with coastal environments and watersheds
