‘A Gradient of Unisons: The Emergent Superunit in Collective Action’
“As design practice shifts from designing material goods to shaping and facilitating social situations, there is a compelling need to develop a richer understanding of specific social relations as facilitated by design. This article explores bodied unisons—enkinaesthetic entrainments of self + other. We present these unison acts as identifiable patterns of behavior that are observable when people coordinate, patterns that foster a move from individual to superunit.” Find the paper and full list of authors at Design Issues.

‘Quasi-Fermi Liquid Behavior in a One-Dimensional System of Interacting Spinless Fermions’
“We present numerical evidence for a paradigm in one-dimensional interacting fermion systems, whose phenomenology has traits of both Luttinger liquids and Fermi liquids. This state, dubbed a quasi-Fermi liquid, possesses a discontinuity in its fermion occupation number at the Fermi momentum. The excitation spectrum presents particlelike quasiparticles and absence of holelike quasiparticles, giving rise instead to edge singularities.” Find the paper and full list of authors at Physical Review B.

‘Rigor With Machine Learning From Field Theory to the Poincaré Conjecture’
“Despite their successes, machine learning techniques are often stochastic, error-prone and blackbox. How could they then be used in fields such as theoretical physics and pure mathematics for which error-free results and deep understanding are a must? In this Perspective, we discuss techniques for obtaining zero-error results with machine learning, with a focus on theoretical physics and pure mathematics. Non-rigorous methods can enable rigorous results via conjecture generation or verification by reinforcement learning. We survey applications of these techniques-for-rigor ranging from string theory to the smooth 4D Poincaré conjecture in low-dimensional topology.” Find the authors list in Nature Reviews: Physics.

‘Milk Exosomes Anchored With Hydrophilic and Zwitterionic Motifs Enhance Mucus Permeability for Applications in Oral Gene Delivery’
“Exosomes have emerged as a promising tool for the delivery of drugs and genetic materials, owing to their biocompatibility and non-immunogenic nature. However, challenges persist in achieving successful oral delivery due to their susceptibility to degradation in the harsh gastrointestinal (GI) environment and impeded transport across the mucus-epithelium barrier. To overcome these challenges, we have developed high-purity bovine milk exosomes (mExo) as a scalable and efficient oral drug delivery system, which can be customized by incorporating hydrophilic and zwitterionic motifs on their surface.” Find the paper and full list of authors at Biomaterials Science.

‘Persistent Anisotropy of the Spin Cycloid in BiFeO3 Through Ferroelectric Switching’
“A key challenge in antiferromagnetic spintronics is the control of spin configuration on nanometer scales applicable to solid-state technologies. Bismuth ferrite (BiFeO3) is a multiferroic material that exhibits both ferroelectricity and canted antiferromagnetism at room temperature, making it a unique candidate in the development of electric-field controllable magnetic devices. … This study provides understanding of the antiferromagnetic texture in BiFeO3 and paves new avenues for designing magnetic textures and spintronic devices.” Find the paper and full list of authors at ArXiv.

Whitford receives NIH grant to ‘enable translation’ across ribosomes
“This award will use theoretical models and high-performance computing to study the ribosome, a massive molecular assembly composed of hundreds of thousands of atoms. The ribosome is responsible for translating our genes into proteins, making its function central to all life. In this study, we will identify the molecular factors that control protein synthesis in bacteria and higher-level organisms. Insights into bacteria will aim to identify novel antibiotics, while the study of human ribosomes can shed light on a range of diseases, including metabolic diseases and forms of cancer.”

‘The Evolutionary Origin of Naturally Occurring Intermolecular Diels-Alderases From Morus alba’
“Biosynthetic enzymes evolutionarily gain novel functions, thereby expanding the structural diversity of natural products to the benefit of host organisms. Diels-Alderases (DAs), functionally unique enzymes catalysing [4 + 2] cycloaddition reactions, have received considerable research interest. However, their evolutionary mechanisms remain obscure. Here, we investigate the evolutionary origins of the intermolecular DAs in the biosynthesis of Moraceae plant-derived Diels-Alder-type secondary metabolites. Our findings suggest that these DAs have evolved from an ancestor functioning as a flavin adenine dinucleotide-dependent oxidocyclase, which catalyses the oxidative cyclisation reactions of isoprenoid-substituted phenolic compounds.” Find the paper and authors list at the National Library of…

‘Developing and Sustaining Northeastern’s Ed.D. Program During and Post Pandemic’
“Northeastern University’s Ed.D. faculty faced unique challenges during the pandemic and racial reckoning following George Floyd’s murder. During this period, however, we found opportunities to adapt and improve our program. We prioritized compassion and connection. We made significant strides in curriculum development through design and implementation of three new concentrations. We focused all program elements on how social justice works in a variety of educational settings. We altered our approach to data collection and doctoral supervision. In so doing, we were able to maintain consistency for our students and develop a closer bond with our faculty colleagues.”

‘Monodromy of the Casimir Connection of a Symmetrisable Kac–Moody Algebra’
“Let g be a symmetrisable Kac–Moody algebra and V an integrable g–module in category O. We show that the monodromy of the (normally ordered) rational Casimir connection on V can be made equivariant with respect to the Weyl group W of g, and therefore defines an action of the braid group Bw on V. … This action is canonically equivalent to the quantum Weyl group action of Bw on a quantum deformation of V, that is an integrable, category O module V over the quantum group Uhg such that V/hV is isomorphic to V.” Find authors at Inventiones Mathematicae.
