Astrocyte‐Guided Maturation of Neural Constructs in a Modular Biosynthetic Hydrogel for Biohybrid Neurotechnologies

open access: yesAdvanced Functional Materials, EarlyView.
A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.

Dual‐Layer Living Hydrogel Enables On‐Demand Delivery of Phages and Probiotics for Synergistic Wound Infection Therapy

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐layer living hydrogel, ProΦGel, integrates bacteriophages and probiotics for synergistic wound infection therapy. The outer gelatin‐based matrix releases phages on demand in response to P. aeruginosa infections, while inner alginate beads sustain probiotic delivery.

Inverse Statistics in the Foreign Exchange Market

open access: yes, 2004
We investigate intra-day foreign exchange (FX) time series using the inverse statistic analysis developed in [1,2]. Specifically, we study the time-averaged distributions of waiting times needed to obtain a certain increase (decrease) $\rho$ in the price

Synthetic Hydrogels Incorporating Hydrolytic/Nonhydrolytic Macromer Ratios Exhibit Improved Tunability of In Vivo Degradation and Immune Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
A synthetic 4‐arm maleimide‐terminated poly(ethylene glycol) (PEG‐4MAL) hydrogel system that combines hydrolytic ester‐linked macromer (PEG‐4eMAL) with nondegradable amide‐linked macromer (PEG‐4aMAL) in various stoichiometric ratios to tune the degradability rate. The macromers are crosslinked with dithiothreitol via thiol‐maleimide click reaction. The
