  • ‘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.

  • ‘Linear Extension and Calcification Rates in a Cold-Water, Crustose Coralline Alga are Modulated by Temperature, Light and Salinity’

    “Long-lived crustose coralline algae are important ecosystem engineers and environmental archives in regions where observations of climate variability are sparse. … Here, we present the results of the first, to-our-knowledge, controlled laboratory experiment isolating the effects of light, temperature, and salinity on calcification rates of C. compactum. Algal calcification rates were modulated by a combination of light exposure, salinity, and temperature, where temperature and salinity were positively correlated, and light level was negatively correlated with calcification rate.” Find the paper and full list of authors in Limnology and Oceanography.

  • ‘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.

  • Ionescu receives NSF CAREER award to study ‘molecular mechanisms of skeletal growth’

    “This Faculty Early Career Development (CAREER) award will focus on elucidating the molecular mechanisms of skeletal growth. … Estrogen plays a vital role in growth plate closure for both sexes [of mammals] by converting androgens to estrogens through aromatase in growth plate cartilage. Deficiency or resistance to estrogen leads to growth plate fusion failure and ongoing height increase in adulthood. However, the exact mechanism by which estrogen regulates growth plate closure is still unknown. Understanding this mechanism may clarify species-specific skeletal differences or variations between bones from different anatomical locations.”

    Associate teaching professor Christopher Barney’s textbook Pattern Language for Game Design looks to the field of architecture for its lessons, specifically architect Christopher Alexander. Using Alexander’s work as a framework, the textbook offers “a series of practical, rigorous exercises [with which] designers can observe and analyze the failures and successes of the games they know and love to find the deep patterns that underlie good design,” the publisher’s webpage states. Using pattern theory, “this book seeks to transform how we look at building the interactive experiences that shape us.”

    “BCL-2-associated X protein (BAX) is a promising therapeutic target for activating or restraining apoptosis in diseases of pathologic cell survival or cell death, respectively. In response to cellular stress, BAX transforms from a quiescent cytosolic monomer into a toxic oligomer. … In this study, we performed a disulfide tethering screen to discover C126-reactive molecules that modulate BAX activity. We identified covalent BAX inhibitor 1 (CBI1) as a compound that selectively derivatizes BAX at C126 and inhibits BAX activation by triggering ligands or point mutagenesis.” Find the paper and full list of authors at Nature Chemical Biology.

  • ‘An Efficient OFDM-Based Monostatic Radar Design for Multitarget Detection’

    “In this paper, we propose a monostatic radar design for multitarget detection based on orthogonal-frequency division multiplexing, where the monostatic radar is co-located with the transmit antenna. The monostatic antenna has the perfect knowledge of the transmitted signal and listens to echoes coming from the reflection of fixed or moving targets. We estimate the target parameters, i.e., range and velocity, using a two-dimensional periodogram. By this setup we improve the periodogram estimation performance under the condition of low signal-to-noise ratio using Zadoff-Chu precoding and the discrete Fourier transform channel estimation.” Find the paper and authors list at IEEE Access.

Currently, DREiMac is able to find topology-preserving representations of point clouds taking values in the circle, in higher dimensional tori, in the real and complex projective spaces, and in lens spaces. In a few words, DREiMac takes as input a point cloud together with a topological feature of the point cloud (in the form of a persistent cohomology class), and returns a map from the point cloud to a well-understood topological space.” Find the paper and full list of authors at the Journal of Open Source Software.

  • Halacheva receives NSF grant for representation theory research

    “This project delves into several research directions within representation theory, which is the mathematical framework for studying objects through their symmetries and the operations which preserve them. Such operations can carry a classical, or even more intriguingly a quantum algebraic structure. … Quantum groups and the theory surrounding them are now a thriving source of uncovering new mathematical principles. This project will develop a richer understanding of this theory by building a common ground for combining algebraic, combinatorial and higher-structural categorical techniques for the study of quantum groups and associated diagram algebras.”

  • Laredo receives NSF grant to bridge ‘classical and quantum symmetries’

    “This project stems from the recent discovery that quantum groups naturally arise from the Stokes data of differential equations associated to classical symmetries. The main goals are to further explore this bridge between classical and quantum symmetries. Of particular interest is the extension to difference equations, which are natural discretisations of differential equations, and whose Stokes data are not well-understood beyond the one-variable case. Another important direction will the study of the integrable systems, or constants of motion, corresponding to these differential and difference equations. The project will provide research training opportunities for graduate students.”
