Researchers at Beijing Institute of Technology have experimentally demonstrated quantized soliton pumping governed by higher-dimensional Chern invariants. Using a time-modulated lattice and its corresponding topolectrical-circuit platform, they observe two-dimensional soliton pumping whose per-cycle displacement is determined by the first and second Chern numbers. Published in National Science Review, this work reveals that, by tuning the nonlinear strength and the linear band structure, the pumping can transition among integer, fractional, trapped, and anisotropic integer–fractional regimes.
Researchers led by physicists at the University of Bath in the UK have found that adding a twist during the fabrication of optical fibres creates a more robust pathway for light, minimising the effects of manufacturing flaws that can cause signals to be lost.
A new method can test whether a large language model contains hidden biases, personalities, moods, or other abstract concepts. MIT researchers can zero in on connections within a model that encode for a concept of interest, to improve LLM safety and performance.
Harvard researchers report a new way to make ultra-smooth, microscopic mirrors that form high-performance optical resonators, or cavities.
New research published this week in JAMA Network Open connects multiple residential factors generally associated with financial strain, such as high housing costs and crowded households, to worse overall outcomes among breast cancer survivors. Led by investigators at VCU Massey Comprehensive Cancer Center, the findings could help inform innovative strategies to increase health care access and ease economic stress for a variety of patients in need.
The human genome is a long sequence of DNA scattered with innumerable genetic variants that distinguish us. Extracting information from large biobank datasets about complex traits, influenced by thousands or millions of variants, remains a challenge. Using human height as a model, researchers at the Institute of Science and Technology Austria (ISTA) have now tackled this problem and developed an enhanced algorithm, published in Cell Genomics, with potential applications in personalized medicine—and even at crime scenes.
