Summary: This study investigated the effects of gamma-ray irradiation on partially fluorinated polystyrene. Poly(4-fluoropolystyrene) and polypentafluorostyrene were prepared using solution polymerization to improve the radiation resistance of polystyrene. The results showed that polypentafluorostyrene exhibited less oxidation and excellent thermal properties after a absorbed dose of 500 kGy, indicating its potential as a promising candidate for radiation resistance applications.

Summary: This paper investigates the application of partially-connected hybrid beamforming design in multi-user integrated sensing and communication systems. The design optimizes the digital and analog beamformers jointly to minimize the Cramer-Rao bound and satisfy the signal-to-interference-plus-noise ratio (SINR) constraints. An alternating optimization based framework is proposed, transforming the optimization problem and efficiently solving it through the proposed algorithm.

Summary: This paper studies the problem of nonblocking supervisor synthesis in partially observed discrete event systems, where supervisors can observe both observable events and the quiescence of the system. They propose a q-observer to characterize the behavior of a system with observable quiescence and develop a method to detect blocking states in the q-observer. An iterative method is then used to synthesize a nonblockingness enforcement supervisor from the q-observer.

Summary: This article explores an unknown input observer design scheme for discrete-time T-S fuzzy singular systems corrupted by process disturbances and measurement noises. Unlike previous results, the premise variables of the considered fuzzy systems are unmeasurable, and the process disturbances are assumed to be only partially decoupled. A novel observer synthesis scheme is developed using the fuzzy Lyapunov function method, which can decouple partial process disturbances and attenuate the influence of non-decoupled process disturbances and measurement noises. The theoretical results are verified through numerical simulations.

Summary: Blends of PLLA with COC show improved miscibility, thermal behavior, morphology, crystallinity, and biocompatibility compared to pure PLLA. The addition of COC decreases the crystallinity of PLLA and forms a new alpha'-crystalline phase, leading to enhanced mechanical properties in the blends. PLLA/COC blends exhibit excellent cytocompatibility and may serve as a potential candidate for Bone Tissue Engineering.

Summary: The membrane structuration of Large Hybrid Unilamellar Polymer/Lipid Vesicle (LHUV) plays a crucial role in optimizing their properties and evaluating their value in various fields. This study focuses on the development of LHUV from the self-assembly of diblock poly(dimethylsiloxane)-b-poly(ethylene oxide) (PDMS-b-PEO) of different molar masses combined with 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). Techniques such as small-angle neutron scattering (SANS) and cryo-transmission electron microscopy (cryo-TEM) were utilized to characterize the hybrid vesicles and their membrane structure, showing that the membrane permeability of LHUV is primarily controlled by the lipid/polymer composition.

Summary: By investigating the relationship between different monomers, it is found that above the critical micellar concentration, there is an exponential relationship between the number of particles and surfactant concentration, with the exponent depending on the polarity of the monomers. When one of the two monomers is highly hydrophobic, the exponent is generally higher.

Summary: This study investigates the preparation of complex polymer colloids through miniemulsion polymerization, focusing on factors such as limited solubility and Ostwald ripening that affect droplet stability. The addition of a radical scavenger can delay polymerization, allowing for the determination of batch photopolymerization kinetics, molecular weight progress, and particle size distribution. The study emphasizes how initiator solubility, droplet size, and monomer solubility impact droplet nucleation.
