Summary: The study introduces an objective method for distinguishing between chemotactic approach and blind migration based on the analysis of time-lapse recorded cell migration trajectories. The method was validated with simulated data and successfully applied to detect long-range interactions in collective systems of self-driven agents in experiments.

Summary: We investigate the radiative heat transfer between two nanoemitters inside different types of closed cavities using fluctuational-electrodynamics approach. Our findings show a strong dependence of heat transfer on cavity width and its matching with material-induced resonance and resonant modes of the cavity. In resonant configurations, this leads to a significantly amplified energy flux compared to the exchange between two emitters in vacuum or between two blackbodies, even at large separation distances. Conversely, slight variations in cavity width can result in a drastic reduction or even inhibition of heat flux. These results provide insights for the design of thermal waveguides for long-distance transport of super-Planckian heat flux and selective heat transfer in many-body systems.

Summary: DNA functions only in aqueous environments and adopts different conformations depending on the hydration level. Investigating the impact of hydration on DNA dynamics and the spectral features of water molecules influenced by DNA is challenging. The dynamics of water molecules in a DNA solution is heterogeneous, with four distinct relaxation times ranging from -8 ps to 1 ns, and the hydration structure of a DNA chain can extend to as far as -18 Å from its surface.

Summary: In this study, we investigate quantum phase transitions in Heisenberg antiferromagnetic chains with staggered power-law decaying long-range interactions. By using the density-matrix renormalization group (DMRG) algorithm and the fidelity susceptibility as the criticality measure, we obtain more accurate values of quantum critical points compared to previous studies. Furthermore, we explore the effects of anisotropic long-range interactions and symmetry breaking, which result in the emergence of various quantum phases.

However, the differences among the surfaces are small. The proposed descriptors are useful for quickly screening polymeric surfaces.

Summary: The study theoretically explores quantum states of a pair of photons interacting with a periodic array of two-level atoms in a waveguide, revealing irregular wave functions and the breakdown of Bethe ansatz, leading to quantum chaos. The long range waveguide-mediated coupling between atoms is identified as the key factor for chaos and nonintegrability in this system, providing new insights into the interplay between order, chaos, and localization in many-body quantum systems.

Summary: Tailoring hopping interactions between constituent elements of a physical system is crucial for observing unusual phenomena. Through the use of non-Hermitian concepts, tailored asymmetric interactions have been realized in photonic integrated platforms, enabling the induction of topological behaviors and the observation of topological responses.

Summary: The study reveals that in budding yeast, telomere clustering is functionally linked to heterochromatin formation, with Sir3 directly promoting long-range contacts between distant regions. Additionally, Sir3 is shown to promote rDNA compaction independently of its known partners, suggesting it acts as a molecular bridge stabilizing long-range interactions.

Summary: Evidence is reported for long-range interactions between logic transitions in unclocked FPGA circuits. These interactions cause pulses in digital feedback loops to dynamically interact and move to equal spacing over long periods of time. The pulse interactions are hypothesized to be caused by current draw in the power distribution network of the FPGA, and have been observed in different FPGA families and manufacturers, including Altera and Xilinx.

Summary: In this study, the authors utilize Schwartz' distribution-theory tools to compare the canonical ensemble treatment of gravity using Boltzmann-Gibbs' and Tsallis' statistics. Through the application of the Cramer Rao inequality, they provide new evidence supporting the conjecture that Tsallis statistics is more suitable for handling long range interactions.

Summary: Phase transitions like KT transition do not necessarily involve symmetry breaking but stem from deeper phenomena. The successful application of topological concepts in studying phase transitions is exemplified by KT transition. In this study, KT transition in a two-dimensional classical XY model is approached from a topological viewpoint focused on energy level sets in phase space.

Summary: This paper investigates the motion of an electron along a chain of heavy particles modeling a sequence of nucleotides in a DNA fragment. It is found that the electron current can display different frequency spectra under the action of an external energy source, indicating a potentially rich variety of electrodynamic interactions of DNA molecules under electron excitation. This suggests possible activation of interactions between DNA and transcription factors, or between DNA and external electromagnetic fields.

Summary: Different arguments suggest that the deep origin of phase transitions is related to suitable topological changes in the configuration space of a physical system. A differential equation has been developed to describe how entropy changes with total energy in the phase space. This research takes a step forward in defining general conditions for topology-driven loss of differentiability of entropy.

Summary: The investigation of the Hamiltonian dynamical counterpart of phase transitions, combined with the Riemannian geometrization of Hamiltonian dynamics, has led to a preliminary formulation of a differential-topological theory of phase transitions. This theory applies to phase transitions in small N systems and in the absence of symmetry-breaking. The present work provides a relevant leap forward leading to an accomplished development of the topological theory of phase transitions paving the way to further developments and applications of the theory.
