Dissecting the Ecological Structure of Health and Disease in the Global Gut Microbiome
Advanced Science, EarlyView.We introduce Wiredancer, a framework that identifies three continuous ecological factors of the gut microbiota. These factors exhibit distinct patterns across health and disease, jointly capturing disrupted ecological stability and offering a new perspective for precision diagnostics and therapeutic strategies.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Degree bounds of minimal polynomials and polynomial automorphisms
Journal of Pure and Applied Algebra, 1994 Let \(k\) be a field, \(h_ 1,\dots, h_ n\in k[x_ 1,\dots, x_{n-1}]=: k^{[n-1]}\) contain \(n-1\) algebraically independent polynomials. The author has shown earlier, that there exists, up to a non-zero constant factor, a unique irreducible polynomial \(m\) in \(n\) variables such that \(m(h_ 1, \dots,h_ n)=0\), called the minimal polynomial of \(h_ 1 ...

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Minimal Polynomials and Distinctness of Kloosterman Sums
Finite Fields and Their Applications, 1995 Let \(q\) be a power of a prime \(p\), and let \(\text{Kl}_n (q,a)\) be the usual multiple Kloosterman sum generated by the rational function \(x_1+ \cdots+ x_n+ a/(x_1 \dots x_n)\) over \(\mathbb{F}_q\). Let \(\xi_p\) be a primitive \(p\)-th root of unity, and let \(H\) be the group of automorphisms \(\theta\) of \(\mathbb{Q} (\xi_p)\) for which ...

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation
Advanced Science, EarlyView.A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Advanced Science, EarlyView.The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...
