  text: Altermagnets are a class of collinear magnets that exhibit non-relativistic
    spin splitting (NRSS) of electronic bands in the absence of net magnetization.
    Their potential to generate large spin polarization without spin-orbit coupling
    has created strong interest in probes that access the underlying order parameter
    directly. In this Perspective, we show that linear magneto-birefringence (LMB)
    provides a natural and broadly applicable route to detecting altermagnetic order.
    Building on the correspondence between the momentum-space structure of NRSS and
    the ferroic ordering of magnetic multipoles in real space, we demonstrate how
    $d$-wave and $g$-wave NRSS textures yield distinct LMB responses. We present a
    symmetry-based framework that identifies the optical geometries and field configurations
    required to isolate specific multipole components, enabling domain imaging and
    providing benchmarks for theoretical models of LMB.

  text: "Evolutionary biology examines how the genetic and phenotypic composition\r\nof
    populations changes over time. An important goal is to determine the\r\nfixation
    probability of a single advantageous mutant that arises in a homogeneous\r\npopulation
    of N residents. Many real populations experience environmental\r\ngradients that
    cause mutations to be beneficial in some spatial\r\nregions but harmful in others.
    Here, we study the fixation probability of a\r\nmutant placed on a simple one-dimensional
    spatial structure that experiences\r\nsuch a gradient. The mutant’s fitness varies
    linearly from1 − s to 1 + s, whereas\r\nthe resident fitness is constant and equal
    to 1. The existing literature suggests\r\nthat such heterogeneity in the mutant’s
    fitness should lead to a decrease in its\r\nfixation probability. However, in
    this work, we find that small, non-negligible\r\ngradients (s < 1=√N) substantially
    increase the fixation probability,while larger\r\ngradients (s > (log N)/√N) substantially
    decrease it.Moreover, we quantify the\r\nstrength of this phenomenon analytically
    and we precisely delimit the range of\r\nthe gradients for which it occurs. Our
    computer simulations closely match\r\nthose findings. Altogether, our results
    indicate that subjecting a simple\r\npopulation structure to natural environmental
    conditions can produce strong\r\ncounterintuitive effects."

  text: "Modern AI systems increasingly rely on opaque, highly complex models whose
    inner workings remain inaccessible even to experts. This opacity creates challenges
    for trust, accountability, and compliance with\r\nemerging regulatory expectations
    such as the “right to an explanation”. While traditional explainability methods—feature
    attributions, counterfactuals, surrogate models—and interpretable model classes
    provide valuable insights for engineers, they often fall short of delivering the
    contextual, conversational explanations that\r\nreal users expect. Large Language
    Models (LLMs) offer a promising new avenue for explanation due to their\r\nability
    to engage interactively, adapt to user needs, and translate technical outputs
    into more accessible reasoning. However, their tendencies toward hallucination,
    conflict avoidance, and oversimplification introduce\r\nserious risks when used
    as explanatory agents. This paper analyzes these opportunities and limitations,
    examines verification strategies for ensuring explanation fidelity, and situates
    LLM-generated explanations within\r\nbroader concerns about public trust. The
    paper concludes by outlining best practices and future research directions for
    building robust, verifiable, and human-aligned explanation systems."

  text: Protein conformational energy landscapes are shaped not only by intramolecular
    interactions but also by their environment. In protein crystals and protein–protein
    complexes, intermolecular contacts alter this energy landscape, but the exact
    nature of this alteration is difficult to decipher. Understanding how the crystal
    lattice affects protein dynamics is crucial for crystallography-based studies
    of motion, yet its influence on collective motions remains unclear. Aromatic ring
    flips in the hydrophobic core represent sensitive probes of such dynamics. Here,
    we compare the kinetics of aromatic ring flips in the protein GB1 in crystals,
    in complex with its binding partner IgG, and in solution, combining advanced isotope
    labelling with quantitative NMR methods. We show that rings in the core flip nearly
    a thousand times less frequently in crystals than in solution. Enhanced-sampling
    molecular dynamics simulations, based on a crystal structure of a GB1 variant
    reported in this work, reproduce these elevated barriers and reveal how the crystal
    restrains motions.

abstract:
- lang: eng
  text: 'Protein conformational energy landscapes are shaped not only by intramolecular
    interactions but also by their environment. In protein crystals and protein-protein
    complexes, intermolecular contacts alter this energy landscape, but the exact
    nature of this alteration is difficult to decipher. Understanding how the crystal
    lattice affects protein dynamics is crucial for crystallography-based studies
    of motion, yet its influence on collective motions remains unclear. Aromatic ring
    flips in the hydrophobic core represent sensitive probes of such dynamics. Here,
    we compare the kinetics of aromatic ring flips in the protein GB1 in crystals,
    in complex with its binding partner IgG, and in solution, combining advanced isotope
    labeling with quantitative NMR methods. We show that rings in the core flip nearly
    a thousand times less frequently in crystals than in solution. Enhanced-sampling
    molecular dynamics simulations, based on a new crystal structure, reproduce these
    elevated barriers and reveal how the crystal restrains motions. '
