Ghuman traces musical intermingling in ‘Resonances of the Raj’
Professor of music Nalini Ghuman’s book “Resonances of the Raj: India in the English Musical Imagination, 1897-1947,” studies the overlooked transmission of musical influences between English and Indian culture “during the last fifty years of the Indo-British encounter,” according to the book’s companion website. “Ghuman reintegrates music into the cultural history of the British Raj, revealing unexpected minglings of peoples, musics and ideas that raise questions about ‘Englishness,’ about the nature of Empire and about the fixedness of identity.”

‘Deploying and Evaluating LLMs to Program Service Mobile Robots’
“Recent advancements in large language models (LLMs) have spurred interest in using them for generating robot programs from natural language, with promising initial results. We investigate the use of LLMs to generate programs for service mobile robots leveraging mobility, perception, and human interaction skills, and where accurate sequencing and ordering of actions is crucial for success. We contribute CodeBotler, an open-source robot-agnostic tool to program service mobile robots from natural language, and RoboEval, a benchmark for evaluating LLMs’ capabilities of generating programs to complete service robot tasks.” Find the paper and full list of authors at ArXiv.

‘Interpretation Issues With “Genomic Vulnerability” Arise From Conceptual Issues in Local Adaptation and Maladaptation’
“As climate change causes the environment to shift away from the local optimum that populations have adapted to, fitness declines are predicted to occur. Recently, methods known as genomic offsets (GOs) have become a popular tool to predict population responses to climate change from landscape genomic data. Populations with a high GO have been interpreted to have a high ‘genomic vulnerability’ to climate change. … This study uses hypothetical and empirical data to explore situations in which different types of fitness offsets may or may not be correlated with each other or with a GO.”

‘Inhalable Bottlebrush Polymer Bioconjugates as Vectors for Efficient Pulmonary Delivery of Oligonucleotides’
“Antisense oligonucleotides hold therapeutic promise for various lung disorders, but their efficacy is limited by suboptimal delivery. To address this challenge, we explored the use of inhaled bottlebrush polymer–DNA conjugates, named pacDNA, as a delivery strategy. Inhaled pacDNA exhibits superior mucus penetration, achieving a uniform and sustained lung distribution in mice.” Find the paper and full list of authors at ACS Nano.

‘The Expressive Function of Public Policy: Renewable Energy Mandates Signal Social Norms’
“Addressing collective action problems requires individuals to engage in coordinated and cooperative behaviours. Existing research suggests that individuals’ propensity to work together depends in part on their belief that others support the cause in question. People form their expectations about prevalent beliefs and behaviours from many sources. To date, most of the literature has focussed on how social norm perceptions are inferred from peers or summary statistics. We explore an understudied source of norm information: the passage of policies by democratically elected institutions.” Find the paper and full list of authors in Philosophical Transactions of the Royal Society B.

‘Local Adaptation in Trait-Mediated Trophic Cascades’
“Predator-induced changes in prey foraging can influence community dynamics by increasing the abundance of basal resources via a trait-mediated trophic cascade. The strength of these cascades may be altered by eco-evolutionary relationships between predators and prey, but the role of basal resources has received limited attention. We hypothesized that trait-mediated trophic cascade strength may be shaped by selection from trophic levels above and below prey. … We suggest that adaptation to basal resource availability may shape geographical variation in the strength of trait-mediated trophic cascades.” Find the paper and full list of authors at Proceedings of the Royal Society B.

‘Does More Advice Help? The Effects of Second Opinions in AI-Assisted Decision Making’
“AI assistance in decision-making has become popular, yet people’s inappropriate reliance on AI often leads to unsatisfactory human-AI collaboration performance. In this paper, through three pre-registered, randomized human subject experiments, we explore whether and how the provision of {second opinions} may affect decision-makers’ behavior and performance in AI-assisted decision-making. We find that if both the AI model’s decision recommendation and a second opinion are always presented together, decision-makers reduce their over-reliance on AI while increase their under-reliance on AI.” Find the paper and full list of authors at ArXiv.

‘Native Capillary Electrophoresis–Mass Spectrometry of Near 1 MDa Non-Covalent GroEL/GroES/Substrate Protein Complexes’
“Protein complexes are essential for proteins’ folding and biological function. Currently, native analysis of large multimeric protein complexes remains challenging. Structural biology techniques are time-consuming and often cannot monitor the proteins’ dynamics in solution. Here, a capillary electrophoresis-mass spectrometry (CE–MS) method is reported to characterize, under near-physiological conditions, the conformational rearrangements of ∽1 MDa GroEL upon complexation with binding partners involved in a protein folding cycle.” Find the paper and full list of authors at Advanced Science.

‘Emotion Regulation Convoys: Individual and Age Differences in the Hierarchical Configuration of Emotion Regulation Behaviors in Everyday Life’
“A key limitation of studying emotion regulation behavior is that there is currently no way to describe individual differences in use across a range of tactics, which could lead to investigations of intraindividual changes over time or interindividual differences as a function of personality, age, culture, or psychopathology diagnosis. We, therefore, introduce emotion regulation convoys. This research tool provides a snapshot of the hierarchy of emotion regulation tactics an individual favors across everyday life situations and how effective they are at regulating moods.” Find the paper and full list of authors at Research Gate.

‘Enabling Rotation Over Electrophoretic Motion in Janus Particles Under Applied Electric Field’
“Janus particles (JPs) comprising metal and dielectric halves are capable of propulsion perpendicular to an applied electric field, with promising applications in targeted drug delivery and microrobotics. Yet, not all JP geometries behave the same when activated. We explore hemispherical, snowman and matchstick-like particle dynamics and evaluate threshold values for which electric torque can overcome induced charge electrophoresis. We define conditions where JPs are more likely to undergo rotation in place rather than linear motion, highlighting design features which should be considered when using these particles as materials.” Find the paper and full list of authors at Applied Physics Letters.

‘The Effects of Lithium Chloride Exposure on the Reproduction of Caenorhabditis elegans’
“Caenorhabditis elegans (C. elegans) are model organisms that share similar anatomical structures to humans. By exploring the effects of lithium chloride (LiCl) on C. elegans, we can collect crucial data regarding the compound’s impact on patients taking psychiatric medications containing LiCl. Here we performed an egg retention assay on nematode populations to explore how LiCl can influence reproduction. We found a statistically significant difference in eggs retained between control and experimental groups, suggesting that LiCl has negative effects on reproductive health.” Find the paper and full list of authors at MicroPublication Biology.
