We consider a new problem in multiterminal source coding motivated by the following decentralized communication/estimation task. A firm's Chief Executive Officer (CEO) is interested data sequence {X(t)}/sub t=1//sup /spl infin// which cannot be observed directly, perhaps because it represents tactical decisions competing firm. The CEO deploys team of L agents who observe independently corrupted versions infin//. Because {X(t)} only one among many pressing matters to must attend, combined...
Abstract Realizing solid‐state lithium batteries with higher energy density and enhanced safety compared to the conventional liquid lithium‐ion is one of primary research development goals set for next‐generation in this decade. In regard, polymer electrolytes have been widely researched as solid due their excellent processability, flexibility, low weight. With high cationic transference numbers ( t Li + close 1), single‐ion conducting (SICPEs) tremendous advantages electrolyte systems <...
Polyhydroxyalkanoates (PHAs) have attracted increasing interest as sustainable plastics because of their biorenewability and biodegradability in the ambient environment. However, current semicrystalline PHAs face three long-standing challenges to broad commercial implementation application: lack melt processability, mechanical brittleness, unrealized recyclability, last which is essential for achieving a circular economy. Here we report synthetic PHA platform that addresses origin thermal...
Dielectric metasurfaces have become efficient tools for creating ultrathin optical components with various functionalities imaging, holography, quantum optics, and topological photonics. While static all-dielectric resonant metaphotonics is reaching maturity, challenges remain in the design fabrication of reconfigurable tunable metasurface structures. A promising pathway toward by incorporating phase-transition materials into photonic structure design. Here we demonstrate Mie-resonant...
Finding ways to tune their states is the key using correlated electron systems in device applications. The authors show how cleanly generate an extremely oxygen-starved environment, which leads collapse of insulating ground state VO${}_{2}$, a prototypical oxide. A nonvolatile metallic phase with unique optical properties stabilized down 2 K by oxygen vacancies, and plus intermediate-resistance can be accessed reversibly via ``oxygen breathing''.
Abstract Self‐healable elastomers are extremely attractive due to their ability prolong product lifetime. An additional function that could further expand applications is strong adhesion force clean and dusty surfaces. This study reports a series of autonomous self‐healable highly adhesive (ASHA‐Elastomer) fabricated via simple, efficient, scalable process. The obtained exhibit outstanding mechanical properties with elongation at break up 2102% toughness (modulus toughness) 1.73 MJ m –3 ....
The current paradigm of elastomer design typically falls into the trade-off between stiffness and extensibility. With a few reports on circumventing this behavior, e.g., increasing Young's modulus without sacrificing extensibility, principles to achieve improvements in both extensibility have rarely been demonstrated. Herein, with model system, i.e., cross-linked polydimethylsiloxane (PDMS) network, we demonstrate two approaches that can surpass stiffness-extensibility provide significant...
To investigate the impact of training sample size on performance deep learning-based organ auto-segmentation for head-and-neck cancer patients, a total 1160 patients with who received radiotherapy were enrolled in this study. Patient planning CT images and regions interest (ROIs) delineation, including brainstem, spinal cord, eyes, lenses, optic nerves, temporal lobes, parotids, larynx body, collected. An evaluation dataset 200 randomly selected combined Dice similarity index to evaluate...
Stereo-defects present in stereo-regular polymers often diminish thermal and mechanical properties, hence suppressing or eliminating them is a major aspirational goal for achieving with optimal enhanced properties. Here, we accomplish the opposite by introducing controlled stereo-defects to semicrystalline biodegradable poly(3-hydroxybutyrate) (P3HB), which offers an attractive alternative isotactic polypropylene but brittle opaque. We enhance specific properties performance of P3HB...
Commercial adhesives are petroleum-based thermoset networks or nonbiodegradable thermoplastic hot melts, making them ideal targets for replacement by biodegradable alternatives. Poly(3-hydroxybutyrate) (P3HB) is a biorenewable and alternative to conventional plastics, but microbial P3HB, which has stereoperfect stereomicrostructure, exhibits no adhesion. In this study, elucidating the fundamental relationship between chemocatalytically engineered P3HB stereomicrostructures adhesion...
Delamination of three-dimensional (3D) printed polymer materials by fused deposition modeling (FDM) is a long-standing challenge in additive manufacturing (AM). With numerous efforts devoted to modification commercially available thermoplastic FDM filaments, developing printing polymeric with new chemical design that could intrinsically improve interlayer adhesion, especially combined other benefits, high demand. Herein, we developed polyurea vitrimer heat-driven malleability, which...

Copolymerization of ethylene (E) and polar vinyl monomers is a great challenge but remains attractive, especially for early transition metal catalysts featuring strong oxophilicity. Herein, we present the copolymerization E with 6-phenoxy-1-hexene (POH) by scandium precatalysts different steric hindrances: (FluCH2CH2NHC)Sc(CH2SiMe3)2 (1), (FluCH2C5H4N)Sc(CH2SiMe3)2 (2), (FluCH2Ph)Sc(CH2SiMe3)2(THF) (3), (C5Me4Ph)Sc(CH2C6H4NMe2-o)2 (4). In comparable conditions, precatalyst 1, activated...
A novel route to fabricate low-cost porous carbon nanofibers (CNFs) using biomass tar, polyacrylonitrile (PAN), and silver nanoparticles has been demonstrated through electrospinning subsequent stabilization carbonization processes. The continuous electrospun had average diameters ranging from 392 903 nm. addition of tar resulted in increased fiber diameters, reduced thermal stabilities, slowed cyclization reactions PAN the as-spun nanofibers. After carbonization, resultant CNFs showed more...
Curcumin (CCM) has many potential uses in anticancer chemotherapy, but its low water solubility poses a major problem, preventing translation into clinical use. TPGS is water-soluble derivative of vitamin E that acts as surfactant with the ability to form micellar nanoparticles water. More importantly, potent antioxidant can neutralize intracellular reactive oxygen species (ROS). In this study, we solubilized CCM using thin-film rehydration prepare aqueous formulations containing at...
