This paper proposes and optimizes a magnetically driven elastic microswimmer that achieves autonomous, nonreciprocal propulsion through hysteretic collapse of its segments, enabling the simultaneous independent control of multiple microrobots via a single oscillating magnetic field for potential medical applications.
This study demonstrates that vibrational strong coupling within an optical cavity can significantly enhance product selectivity in post-transition state bifurcation reactions by altering dynamical outcomes through cavity-system and intramolecular energy transfer, thereby establishing cavity quantum electrodynamics as a viable tool for reshaping chemical reaction pathways.
This paper demonstrates that transition waves can be controlled in mechanical metamaterials composed of intrinsically monostable units by programming their energy landscapes through neighbor interactions, enabling discrete, directionally unbiased wave propagation without relying on intrinsically multistable building blocks.
By engineering a five-layer 10° twisted graphene Moiré superlattice on a silicon-on-insulator substrate, researchers achieved a record-breaking carrier multiplication gain of 10³ via enhanced interlayer coupling and a thermalized optical phonon bottleneck, enabling highly sensitive near-infrared single-photon detection with a signal-to-noise ratio exceeding 100 dB.
This study demonstrates that non-Hermitian loss contrast can induce and reversibly switch higher-order topological edge and corner states in acoustic fractal lattices, providing a new mechanism for manipulating topological phases in non-integer dimensions without altering the underlying lattice structure.

This paper proposes a self-consistent model explaining anomalously large nickel isotope enrichment in ultrafast laser ablation plasmas through a magnetic centrifuge mechanism driven by rapid ion cyclotron rotation and Ion Bernstein Waves, rather than hydrodynamic plasma rotation.
This paper proposes a simple, software-based feedforward compensation method that identifies and corrects four distinct sources of piezoelectric nonlinearity, achieving an order-of-magnitude improvement in positioning accuracy without compromising the high-speed imaging capabilities of atomic force microscopy.
This paper demonstrates that deterministic chaos can emerge in bounded 3D dynamical systems even when the Jacobian is pointwise spectrally contracting, revealing that non-normality-driven transient amplification via endogenous switching constitutes a distinct route to chaos independent of spectral criticality.
This study demonstrates that increasing particle elasticity governs the non-equilibrium self-assembly of colloidal microgels at a drying air-water interface, driving a transition from repulsion-stabilized crystallization to attraction-dominated gelation through diverse metastable structures, a phenomenon successfully reproduced by molecular dynamics simulations incorporating hydrophobic, capillary, steric, and dipolar interactions.
This paper presents a theoretical design for a single-heat-source power generation cycle using R134a that claims to bypass the Carnot limit by leveraging asymmetric constraints to harvest ambient heat and produce net work from a micro temperature difference.
This study demonstrates that delivering low-energy (2.5 MV) photon beams at an extended source-to-patient distance (4 m) in an upright configuration achieves significantly sharper penumbra, lower surface dose, and higher peak-to-valley ratios in spatially fractionated plans compared to standard 6 MV coplanar radiotherapy, offering a viable alternative to FLASH for high-flux sources.
This paper presents a GPU-accelerated transient Electromagnetic-Thermal-Mechanical co-simulation solver that enables full-scale, non-homogenized early-stage design of advanced packages, overcoming the limitations of conventional steady-state methods by accurately capturing dynamic signal-induced stress and thermal events to prevent costly late-stage failures.
