Opinion Analysis through Constraint Optimisation [PDF]
Opinion lexicon plays a vital role in sentiment classifi cation. A previous study shows that a compositional model can be e ective in sentiment classifi cation. But such a model has been only applied using hand-crafted composition rules.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Cell polarity changes in cancer initiation and progression
International audienceCell polarity, which consists of the morphological, structural, and functional organization of cells along a defined axis, is a feature of healthy cells and tissues. In contrast, abnormal polarity is a hallmark of cancer cells.

Chemical Strategies for Multistimuli Responsive Dynamic Covalent Materials in Regenerative Medicine
Multistimuli responsive dynamic covalent materials integrate reversible chemistry with the complex chemical, mechanical, and biochemical cues of regenerative environments. This review highlights chemical strategies based on orthogonal dynamic bonds, multicomponent networks, and hierarchical architectures to regulate mechanics, degradation, and ...

Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...
