Covid-19 Circuit Breaker: impacts on daily routine, social media usage and psychological well-being In Singapore and OverseasGiulio Gabrieli, Ilaria Cataldo & Gianluca Esposito
The purpose of study is to investigate how individual features, such as personality traits, biological sex, age, influence the quantity and type of usage of social media platforms across the spectrum of psychological well-being during the time of circuit breaker due to the Covid-19 pandemic. Results found that personality traits were differently predictive for active and passive usage of Facebook, Instagram, and Twitter during the pandemic. Moreover, results highlighted that psychosocial aspects of social media...

Picture Cards for eliciting speech in different languages. The pictures were designed to elicit the syllables /pi/ /pa/ and /pu/ in the word onset position in the official languages of Singapore: English, Chinese, Malay, and Tamil. The picture cards were first piloted in 2019, and rolled out for elicitation tasks as part of the Talk Together Study in 2020.
Replication Data for: Highly Efficient Thermally Co-evaporated Perovskite Solar Cells and Mini-modulesJia Wei Melvin Lim
The rapid improvement in the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has prompted interest in bringing the technology toward commercialization. Capitalizing on existing industrial processes facilitates the transition from laboratory to production lines. In this work, we prove the scalability of thermally co-evaporated MAPbI3 layers in PSCs and mini-modules. With a combined strategy of active layer engineering, interfacial optimization, surface treatments, and light management, we demonstrate PSCs (0.16 cm2 active area) and...
Replication Data for: Hypergraph based persistent cohomology (HPC) for molecular representations in drug designKelin Xia
Artificial intelligence (AI) based drug design has demonstrated great potential to fundamentally change the pharmaceutical industries. Currently, a key issue in AI-based drug design is efficient transferable molecular descriptors or fingerprints. Here, we present hypergraph-based molecular topological representation, hypergraph-based (weighted) persistent cohomology (HPC/HWPC) and HPC/HWPC-based molecular fingerprints for machine learning models in drug design. Molecular structures and their atomic interactions are highly complicated and pose great challenges for efficient mathematical representations. We develop the first...

Constructing an Adaptive Heterojunction as a Highly Active Catalyst for the Oxygen Evolution ReactionXiao Ren
Electrochemical water splitting is of prime importance to green energy technology. Particularly, the reaction at the anode side, namely the oxygen evolution reaction (OER), requires a high overpotential associated with OO bond formation, which dominates the energy-efficiency of the whole process. Activating the anionic redox chemistry of oxygen in metal oxides, which involves the formation of superoxo/peroxo-like (O2)n−, commonly occurs in most highly active catalysts during the OER process. In this study, a highly active...

Recently, metasurfaces based on phase-change materials (PCMs) have attracted increasing attention due to the dramatic optical properties contrast between amorphous and crystalline state. The chalcogenide PCMs can be reversibly switched by electrical or optical pulses, offering tunability and reconfigurability for the metasurfaces. In this review, the latest achievements and ongoing development in reconfigurable metasurfaces based on chalcogenide PCMs are presented, including the applications in nonlinear optics, anapole control, beam steering, perfect absorber and polariton. The...
Extreme terahertz (THz) science and technologies, the next disruptive frontier in nonlinear optics, provide multifaceted capabilities for exploring strong light-matter interactions in a variety of physical systems. However, current techniques involve the need for an extremely high-field free space THz source that is difficult to generate and has limited investigations to a rather weak and linear regime of light-matter interactions. Therefore, new approaches are being sought for the tight confinement of THz waves that can...
This study aims to examine the motivational profiles of Malay students in Singapore-based self-regulated learning framework (Pintrich De Groot, 1990) and self-determination theory (SDT; Deci Ryan, 1985). The sample consisted of 740 secondary school students from 24 tuition centres for Malay students only. The students were from three academic streams in Singapore (Express, Normal-academic, and Normal-technical). Using cluster analysis, five different clusters of students were found based on their unique characteristics on self-regulation and learning...

Heightened stress during air pistol competitions may impair shooters’ abilities to maintain gun stability, resulting in inferior performance. This study aimed to compare the pre-trigger muscle activation levels of upper muscles in 10-m air pistol shooters between training and simulated competition conditions. Seven sub-elite shooters from the Singapore National Youth Air Pistol Team shot 30 shots in a training versus simulated competition condition in randomised orders on separate days. Muscle activation for the forearm and...

Guided by Basic Psychological Need Theory, we investigated the combined associations between need satisfaction and need frustration (i.e., need profiles) and their relations with theoretically relevant correlates including mindfulness, physical literacy, physical activity enjoyment, and physical activity. The participants were Singapore based school students (N = 844, Mage = 12.45, SDage = 1.99, boys = 53.1%) who completed a cross-sectional survey. The results of the latent profile analysis identified four distinct need profiles: profile 1–average...
