Advanced Science, EarlyView.Coexisting DCIS and IDC samples are profiled using spatial transcriptomics, single‐cell RNA sequencing, and single‐cell DNA sequencing. Integrative multi‐omics analysis reveals distinct malignant epithelial and microenvironmental features between DCIS and IDC, which are further validated using Xenium and multiplex immunohistochemistry.

On the membership problem for the {0, 1/2}-closure [PDF]
, 2011 In integer programming, {0,1/2}-cuts are Gomory–Chvátal cuts that can be derived from the original linear system by using coefficients of value 0 or 1/2 only. The separation problem for {0,1/2}-cuts is strongly NP-hard.

Integer solutions of by2 + pn = x3
Journal of Number Theory, 1975 AbstractThe equation by2 + pn = x3 is regarded as a diophantine equation in the integer variables x, y, and n. Solutions of such equations are explicitly constructed for a large class of parameters b and p. For example, the five families of solutions to the equation y2 + 11n = x3 are given. Indeed, the conditions on b and p and the proofs can be viewed

Experiments on Nonlocal Fluid‐Flow Metamaterials
Advanced Science, EarlyView.A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.

Enhancing Quasi‐Two‐Dimensional Electronic Structure in Bi2O2Se via Chlorine Substitution
Advanced Science, EarlyView.We demonstrate chlorine substitution as an effective strategy to transform Bi2O2Se into an exfoliatable van der Waals superlattice. Key electronic band feature, including indirect bandgap, effective mass is well preserved, while the 2D character of the system is sufficiently enhanced.

FATCOP: A Fault Tolerant Condor-PVM Mixed Integer Programming Solver [PDF]
, 1999 We describe FATCOP, a new parallel mixed integer program solver written in PVM. The implementation uses the Condor resource management system to provide a virtual machine composed of otherwise idle computers.

cis‐Carboxylate Enhancement of Mn(III)‐OH Hydrogen Atom Abstraction through PCET Thermodynamics
Advanced Science, EarlyView.ABSTRACT Manganese(III)‐hydroxo intermediates are proposed as key hydrogen atom abstraction (HAA) species in manganese‐dependent enzymes, yet how first‐sphere carboxylate ligands control their proton‐coupled electron transfer (PCET) thermodynamics remains poorly understood.

Advanced Science, EarlyView.A dual‐randomness hardware platform is demonstrated by integrating PUF and TRNG functionalities into mixed‐ZGO nanoclusters. By leveraging spatial and temporal stochasticity, the mixed‐ZGO NCs device enables both unique identification and random signal generation.

Advanced Science, EarlyView.Inspired by the twin grain boundary discovered in natural gyroidal networks, a series of gyroid‐derived photonic crystals are constructed based on defect‐symmetry engineering. The new series of structures enables monotonic tuning of the width of the photonic bandgap (PBG) while the central frequency of the PBG maintains stable.
