Summary: A new approach to studying nonrelativistic bosonic string in flat spacetime has been introduced, utilizing a holistic Hamiltonian analysis of the minimal action for the string. The study resulted in a structurally new form of the action, equivalent to known results under appropriate limits. The interplay between different types of actions was established through a detailed analysis of symmetries using constraint analysis, clarifying various issues in existing literature.

Summary: This paper introduces a new definition for regular and indeterminate strings and proposes a linear time algorithm to determine regular strings. It connects the regularity of strings to the transitive closure problem on a graph and introduces the concept of a feasible palindrome array. The paper also outlines new research directions suggested by this changed perspective on regular and indeterminate strings.

Summary: We report the first discovery that in the heterotic string compactified on a 4-torus or equivalently the IIA string compactified on K3, the leading alpha' corrections to the entropy of rotating black strings at fixed conserved charges can be negative. This implies that the correction to the mass of extremal rotating strings is positive, contrary to the standard expectation from the weak gravity conjecture. Our findings suggest that the validity of the positivity of entropy shift due to higher order operators depends on other factors that were previously omitted in the effective field theory analysis.

Summary: We study the first-order alpha ' corrections to a general family of supersymmetric heterotic backgrounds that describe a rotating superposition of a fundamental string and a momentum wave. Even after taking into account these corrections, the singularity at the horizon of the resulting black ring in five dimensions persists, contrary to previous arguments in the literature.

Summary: Alpha'(2) curvature corrections to the NS5-brane action can dramatically alter the KPV analysis, requiring a large S-3 radius to recover the leading-order KPV potential. These corrections lower the tension of the brane, potentially achieving a small uplift through tuning of curvature corrections.

Summary: The study reports the effects of enhanced magnetic fields from type-II superconducting NbTiN slabs on narrow Hall bar devices made of epitaxial graphene, and suggests that changes in magnetoresistance are minimally affected by other factors. Abrikosov vortices in type-II superconductors are hypothesized to contribute to the observations, and the London penetration depth combined with Ginzburg-Landau theory can estimate the upper limit of the impact of vortex densities at low fields on the reported observations. These analyses provide insights into device fabrication and the utilization of the Meissner effect in low-field and low-temperature applications using superconductors.

Summary: In this study, non-extremal dyonic string solutions were constructed in 6D minimal supergravity, with higher derivative corrections obtained from either the type IIA string theory or the heterotic string theory. It was found that the α' corrections can affect the attractive force in the isoentropic process near extremality, while not affecting the mass-to-charge ratio. On the other hand, in the isothermal or isoenergetic processes, the α' corrections can enhance the attractive force.

Summary: The article demonstrates the efficient determination of leading derivative corrections to the Heisenberg-Euler effective action from the vacuum polarization tensor evaluated in a homogeneous constant background field. With an explicit parameter-integral representation derived for these corrections in generic electromagnetic fields at one loop, the focus then shifts to magnetic- and electric-like field configurations where closed-form results and all-orders weak- and strong-field expansions can be obtained. An important application highlighted is the leading derivative correction to the well-known Schwinger formula, describing the decay of quantum vacuum through electron-positron pair production in slowly varying electric fields.

Summary: This study revisits the calculation of quantum-gravitational corrections to the power spectra of scalar and tensor perturbations in the Born-Oppenheimer approach to quantum gravity. The focus is on defining the inner product of the theory and ensuring the unitarity of the corrections to the dynamics of the cosmological perturbations. The results suggest that the correction terms are unitary when the inner product is appropriately defined, which can be related to a notion of gauge fixing the time variable and using conditional probabilities in quantum cosmology.

Summary: Understanding the links between development and evolution is a major challenge in biology. This study introduces a new approach, called Energy Proxy Traits (EPTs), to quantify organismal development as high-dimensional landscapes of energy spectra in video. The findings show that changes in event timings can influence the high-dimensional phenotypic space, providing a new perspective on the importance of developmental event timing in evolution.

Summary: As the temperature increases, the Effective String Theory accurately predicts several universal features of confining gauge theories, and its behavior near the deconfinement point is in good agreement with predictions based on conformal invariance or dimensional reduction, further supporting the validity of using an Effective String Theory approach to confinement.

Summary: This study investigates the impact of two rounds of whole genome duplication on the architecture of the vertebrate gene regulatory networks. The findings reveal that these duplication events enriched the network with complex network motifs and enhanced combinatorial organization, potentially affecting the network's robustness and high-level functions. The research supports the hypothesis that whole genome duplications played a significant role in the emergence of complex traits in vertebrates.

Summary: This study created a genome-wide 3D atlas of the mouse olfactory mucosa using spatial transcriptomics. The distribution of odorant receptor genes (Olfrs) and non-Olfrs in different regions was found to be continuous and overlapping. The spatial locations of Olfrs correlated with the solubility of the odorants they recognized, providing evidence for the chromatographic theory of olfaction.

Summary: In this study, we investigate the infrared dynamics of the three-dimensional SU(2) Yang-Mills theory using the effective string. By combining high-precision lattice simulation results with analytical constraints and predictions from various theories, we derive quantitative bounds on the corrections to the effective string action. The results are consistent with the predictions from the effective string theory, but do not prove the Axionic String Ansatz for this model.

Summary: This work demonstrates that the theoretical framework of stochastic normalizing flows, combined with Monte Carlo updates, is the same as the framework underlying out-of-equilibrium simulations based on Jarzynski's equality. This provides a promising approach to sample lattice field theories more efficiently and the study offers strategies and examples of applications for optimizing the efficiency of generative models.

Summary: Large-scale data on single-cell gene expression can be analyzed through the statistics of their basic building blocks, similar to linguistics, ecology, or genomics. A mathematical framework can uncover emergent statistical laws in single-cell transcriptomic data and explore the underlying mechanisms. Treatable statistical models are valuable tools to distinguish biological variability from statistical effects and sampling process in transcriptomics.

Summary: The study shows that even with string breaking in the three-dimensional SU(2) Higgs model, the confining part of the interquark potential can still be accurately described by effective string theory. Furthermore, the fine details of the effective string, such as higher order terms of the Nambu-Goto action or boundary corrections, can be precisely extracted from fits and agree with the predictions of effective string theory.
