Electrical characterization of bias temperature instability in MOSFETs with the ultrathin SiON and la-doped HfSiO gate dielectrics by Du, Guoan.

“…Under certain stress voltage and temperature, the number of E'δ centers is saturated because the reaction of pre-existing oxygen vacancies at shallow regime reaches its dynamic balance. On the other hand, lengthening of the stress time allows the generation of deeper hole trap states arising greater structural relaxation through increased interaction with lattice phonons. …”

Modeling, optimization and thermal characterization of micropillar evaporator based high performance silicon vapor chamber by Wei, Mengyao

“…Investigation on wettability performance of micropillar structures was not systematically extended to a high temperature regime. In this thesis, we developed three semi-analytical models in predicting the capillary-limited dryout heat flux of uniform evaporators, biporous evaporators and sealed silicon vapor chambers. …”

Prediction of stable perovskite quantum dots (QDs) using machine learning (ML) algorithms by Cheong, Ivan

“…However, they have not been widely studied, with applications limited to solar cells and catalytic activity, the full extent of possible applications are yet to be realised. At the nano regime the properties are often different and can be controlled, this is due to quantum confinement and larger surface to volume ratio, which can be adjusted by controlling the size, subsequently able to use for various application. …”

Theoretical study on forced convection filmwise condensation inside converging channels in the presence of a non-condensable gas by Liu, Pengfei, Ho, Jin Yao, Kandasamy, Ranjith, Wong, Teck Neng

“…When the air mass fraction is high (W=0.4), the enhancement ratio appears to be insensitive to the Reynolds number in the laminar and turbulent regime, respectively. In addition, the enhancement ratio generally increases as the air mass fraction increases.…”

High cycle fatigue characterisation and modelling of 316L stainless steel processed by laser powder bed fusion by Zhang, Meng

“…In the presence of tensile mean stress, variations in the plastic deformation properties, as demonstrated by the effects of build orientation and post-processing treatments (annealing or hot isostatic pressing), were found to induce cyclic plasticity, which led to strong fatigue-ratcheting interactions in the high cycle fatigue regime. The simultaneous actions of ratcheting and fatigue generate complex nonlinear relationships between the stress amplitude and mean stress parameters, such that the fatigue properties could not be effectively predicted using traditional stress-based models. …”

Institutions and agricultural transformation: a study of induced innovation in the Philippine rice sector by Montesclaros, Jose Ma. Luis P.

“…Research findings supported the hypotheses that agricultural transformation was impeded by the three factors: 1) an industrialisation-inspired de-facto currency overvaluation regime removed farmers’ potential to capture export markets, the latter serving as a “carrot” for adopting innovation; 2) trade protectionist policies in the rice sector removed import competition as a “stick” for adopting innovation; and 3) industrialisation- and land reform-related capital scarcity among smallholder farmers hindered the dynamics of IIA from taking place. …”

GPU-based commonsense reasoning for real-time query answering and multimodal analysis by Tran, Ha Nguyen

“…Secondly, in order to reason and retrieve information on rule-based knowledge bases, the thesis introduces gSparql, a fast and scalable inference and querying method on mass-storage RDF data with rule-based entailment regimes. Our approach accepts different rulesets and executes the reasoning process at query time when the inferred triples are determined by the set of triple patterns defined in the query. …”

Dimensionality-dependent type-II Weyl semimetal state in Mo₀.₂₅W₀.₇₅Te₂ by Li, Peiling, Deng, Ya, Hsu, Chuang-Han, Zhu, Chao, Cui, Jian, Yang, Xue, Zhou, Jiadong, Hung, Yi-Chun, Fan, Jie, Ji, Zhongqing, Qu, Fanming, Shen, Jie, Yang, Changli, Jing, Xiunian, Lin, Hsin, Liu, Zheng, Lu, Li, Liu, Guangtong

“…Here, by selecting a special sample with the thickness gradient across two- (2D) and three-dimensional (3D) regime, we show strong evidences that Mo$_{0.25}$W$_{0.75}$Te$_{2}$ is a type-II Weyl semimetal by observing the following two dimensionality-dependent transport features: 1) A chiral-anomaly-induced anisotropic magneto-conductivity enhancement, proportional to the square of in-plane magnetic field (B$_{in}$$^{2}$); 2) An additional quantum oscillation with thickness-dependent phase shift. …”
