Bondi mass with a cosmological constant by Saw, Vee-Liem

“…Furthermore, with MΛ=MB, we show that for purely quadrupole gravitational waves given off by the isolated system (i.e., when the “Bondi news” σo comprises only the l=2 components of the spherical harmonics with spin-weight 2) the energy carried away is manifestly positive definite for the Λ>0 case. …”

Mussel-inspired approach to cross-linked functional 3D nanofibrous aerogels for energy-efficient filtration of ultrafine airborne particles by Zhang, Youfang, Zeng, Zhihui, Ma, Daphne Xiu Yun, Zhao, Chenyang, Ang, Jia Ming, Ng, Bing Feng, Wan, Man Pun, Wong, Shing-Chung, Wang, Zhe, Lu, Xuehong

“…Morphology characterization andcompression tests showthatboth multiplehydrogen bondingfacilitated bythePDA coating and Fe3+-PDA coordination bonding could effectively induce the formation of inter-fiber junctions, enhancing compression resistanceofthe3DNFAsandleadingtohierarchical porousstructureswithaverywidePSD.When a thin layer of the optimized 3D NFA with a large specific surface area (85.7m2g−1) is combined with a commercial air filter, the composite filter obtained exhibits high filtration efficiencies of 99.72% and 99.85% for airborne particles with sizes of<100nm and<500nm, respectively, at a low pressure drop of only 54.1Pa. …”

Direct tensile test on brittle rocks with the newly developed centering apparatus by Zhang, Qiangyong, Duan, Kang, Xiang, Wen, Yuan, Shengbo, Jiao, Yu-Yong

“…A new set of centering apparatuses, which consist of the specimen bonding part and the axial pulling part, were developed in this study. The misalignments when bonding the specimen and conducting the uniaxial tensile test can be effectively eliminated. …”

Quantitative evaluation of stone fragments in extracorporeal shock wave lithotripsy using a time reversal operator by Wang, Jen-Chieh, Zhou, Yufeng

“…Although ultrasonic and fluorescent imaging are used to localize the calculi, it’s challenging to monitor the stone comminution progress, especially at the late stage of ESWL when fragments spread out as a cloud. The lack of real-time and quantitative evaluation makes this procedure semi-blind, resulting in either under- or over-treatment after the legal number of pulses required by FDA. …”

The contribution of color information to rapid face categorization in natural scenes by Or, Charles C.-F., Retter, Talia L., Rossion, Bruno

“…Behavioral analysis revealed longer response times when images contained color, despite nearly-all-correct performance in all conditions, suggesting that color change in the task might detract from color’s contribution to face categorization. …”

Asynchronous control network optimization using fast minimum cycle time analysis by Law, Chong Fatt, Gwee, Bah Hwee, Chang, Joseph Sylvester

“…The novelty of the proposed algorithm is that it takes advantage of the fact that only small modifications are made to the control network during each optimization iteration. When applied to nontrivial designs, the proposed optimization methods provided significant reductions in transistor count and energy dissipation in the designs’ asynchronous control networks while satisfying the throughput constraints.…”

Lipopolysaccharide neutralizing peptide–porphyrin conjugates for effective photoinactivation and intracellular imaging of gram-negative bacteria strains by Liu, Fang, Soh, Annie Yan Ni, Lim, Yingjie, Mohanram, Harini, Bhattacharjya, Surajit, Xing, Bengang

“…The intracellular fluorescent imaging and photodynamic antimicrobial chemotherapy (PACT) studies supported our hypothesis that the PpIX-YI13WF conjugates could serve as efficient probes to image the bacterial strains and meanwhile indicated the potent activities against Gram-negative bacterial pathogens especially for those with antibiotics resistance when exposed to the white light irradiation. Compared to the monomeric PpIX-YI13WF conjugate, the dimeric conjugate indicated the stronger fluorescent imaging signals and higher photoinactivation toward the Gram-negative bacterial pathogens throughout the whole concentration range. …”

Laplacian embedded regression for scalable manifold regularization by Chen, Lin, Tsang, Ivor Wai-Hung, Xu, Dong

“…The benefits of the transformed kernel are two-fold: (1) we can deal with the original kernel matrix and the graph Laplacian matrix in the graph kernel separately and (2) if the graph Laplacian matrix is sparse, we only need to perform the inverse operation for a sparse matrix, which is much more efficient when compared with that for a dense one. Inspired by kernel principal component analysis, we further propose to project the introduced decision variable into a subspace spanned by a few eigenvectors of the graph Laplacian matrix in order to better reflect the data manifold, as well as accelerate the calculation of the graph kernel, allowing our methods to efficiently and effectively cope with large scale SSL problems. …”

The future of nuclear power in India: a question of liability law by Sengupta, A

“…Two specific provisions are particularly contentious:</p> <ul> <li>Section 17(b) which holds suppliers liable for recourse when a nuclear incident results from either a patent or a latent defect in the equipment or material supplied, or as a result of the supply of substandard services; and</li> <li>Section 46 which arguably allows suppliers to remain liable under regular provisions of tort law and other general legislation despite having fulfilled their liabilities under this Act.…”

Probing the effect of oxygen vacancies in strontium titanate single crystals by Rahman, S

“…The 4×4 and 6×6 reconstructed surfaces encourage the formation of close-packed structures upon the deposition at room temperature. When the surface covered with fullerenes is heated to a temperature of around 200 °C, epitaxial islands are observed. …”

Neural and psychological correlates of stuttering by Demirel, B

A novel human stem cell platform for probing adrenoceptor signaling in iPSC derived cardiomyocytes including those with an adult atrial phenotype by Ahmad, F

“…</p> <p>A culture programme involving the use of Gremlin 2 allowed differentiation of cardiomyocytes with an atrial phenotype from human induced-pluripotent stem cells. When these differentiated cultures were dissociated into single myocytes a substantial fraction of cells showed a rod-shaped morphology with a single central nucleus that was broadly similar to that observed in cells isolated from atrial chambers of the heart. …”

Content learning in Japanese and English medium instruction: comparing chemistry learning outcomes in Japanese higher education by Aizawa, I

“…The study also found that EMI students with lower English language proficiency faced considerably more onerous challenges than their more proficient counterparts when learning through EMI. Meanwhile, a range of factors also emerged as crucial facilitators for success in EMI, such as previous exposure to EMI education, motivation, revision and preparation, and learning strategies. …”

Policy design and professional service delivery performance of drinking water services in rural Mali by Wagner, J

“…Notably, users appear more inclined to pay a volumetric tariff at solar kiosks, resulting in improved revenue generation. Additionally, when payment modalities switch from volumetric to monthly flat fees, a handpump registers, on average, more than three times higher monthly revenue, along with a two-fold increase in daily water use. …”

Exploring population structure, antibiotic resistance and horizontal gene transfer in Neisseria gonorrhoeae by Unitt, A

“…The results were as follows: 1) A new, stable taxonomic nomenclature using LIN codes was developed, and demonstrated to provide improved resolution and reliability when defining gonococcal lineages. 2) The most common species contributing to mosaic <em>N. gonorrhoeae penA</em> alleles were shown to be <em>Neisseria subflava</em> and <em>Neisseria cinerea</em>, and resistance associated polymorphisms were found to be widespread across the genus. 3) African gonococci were shown to predominantly carry non-mosaic <em>penA</em> alleles and belong to a distinct range of lineages, with LIN code lineage 0_0_33 dominating, while common global lineages 0_2_0 and 0_2_1 were rare.…”
