Automatic writing assessment for ESL students by Gong, Mingyi

“…The target candidates of CET contain both undergraduate and postgraduate non-English-specialized students in the universities. There are two bands of CET, CET4 and CET6. Results of these two tests represent the English proficiency of students, and are highly concerned by companies and universities if the students would like to be hired or engage in advanced studies. …”

Unveiling the chirality of the quantum anomalous Hall effect by Chen, Hongyu, Jin, Yuanjun, Mohammad Yahyavi, Belopolski, Ilya, Shao, Sen, Hou, Tao, Wang, Naizhou, Hsu, Chia-Hsiu, Zhao, Yilin, Yang, Bo, Ma, Qiong, Yin, Jia-Xin, Xu, Su-Yang, Gao, Weibo, Chang, Guoqing

“…Here, for the electronic structures of intrinsic QAHE systems, we show that the local Berry curvature is linked with the angular-momentum difference lδz of the inverted bands. In the presence of rotation symmetries, the value of lδz will be quantized and set as the Chern number. …”

Novel receiver design for suppression of frequency-hopped multiple-access (FHMA) systems by Muhammad Faizal Razali

“…Following that we introduce multiple access interference to simulate and study the result of the bit error rate (BER) when multiple users and different number of frequency bands are included. We include five diversity combining techniques and simulate the results in order to study if they help improve the BER of the FHMA system. …”

Experimental investigation and crystal plasticity modelling of dynamic recrystallisation in dual-phase high entropy alloy during hot deformation by Zhou, Z, Huo, Y, Wang, Z, Demir, E, Jiang, A, Yan, Z, He, T

“…In the initial stage of deformation, stress concentrates at the grain boundaries and interface boundary and then propagate to the deformation bands with temperature. The BCC phase undergoes continuous dynamic recrystallisation (CDRX), displaying significant differences from the DRX mechanism of the FCC phase, leading to asynchrony between the two phases during DRX. …”

Understanding structural variations in elastic organic crystals by in situ high-pressure Fourier transform infrared spectroscopy and nanoindentation study by Ganguly, Somnath, Chinnasamy, Ragaverthini, Parikh, Shyamal, Kiran, Mangalampalli S. R. N., Ramamurty, Upadrasta, Bhatt, Himal, Deo, Mukul Narayan, Ghosh, Soumyajit, Ghalsasi, Pallavi

“…The infrared stretching wavenumber of the aromatic and aliphatic C-H, H-C=N, and C-Cl bands on compression showed blueshifts and increased widths, which reflect structure perturbation caused by changes in intermolecular interactions in the crystals. …”

Perspective: bonding and electronic origin of Au atomic-undercoordination-derivacy and nanoscale-size-dependency by Sun, Changqing

“…Systematic analysis of the electron emission spectra of XPS and STM/S of the undercoordinated gold atoms revealed that the 4f and 5d bands undergo quantum entrapment while the 6s level is subject to localization and polarization because of the undercoordination-induced local bond contraction and bond strength gain – named bond order-length-strength correlation and nonbonding electron polarization (BOLS-NEP). …”

3D surface analysis of coral microatolls by Gautam, Rohan

“…Studying microatolls is typically done by slabbing, an invasive process where a radial slice is obtained in order to study its annual growth bands. This is an invasive method. In this paper, we aim to lay a foundation for non-invasive analysis of coral properties by studying the 3d surface of the corals collected through LIDAR and photogrammetry techniques. …”
