Matching TGF‐β1 Activation With Stress‐Responsive Charge‐Reversal Hydrogel Microspheres for the Treatment of Osteoarthritis

Exploration, EarlyView.
Based on the interaction between the weakly cross‐linked disulfide bonds that break under stress and charge‐reversal messenger molecules, we herein achieved nanoparticle charge reversal under stress and constructed a stress‐responsive charge‐reversal hydrogel microsphere system using microfluidic technology.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

Packet-loss robust scalable authentication algorithm for compressed image streaming

Tongxin xuebao, 2014
Based on structures and dependencies of the image codestreams, a scalable stream-level authentication ap-proach was proposed to resist packet loss. To construct the authentication algorithm by hash chaining and error-correction coding, the proposed ...

Generalized Hash Chain Traversal with Selective Output

IEICE Transactions on Information and Systems, 2010
A hash chain H for a one-way hash function h(·) is a sequence of hash values , where v0 is a public value, vn a secret value, and vi =h(vi+1). A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1 ≤ i ≤ n.

The effect of nearby listings on house sale prices in Sydney: A spatio‐temporal regularization approach

Real Estate Economics, EarlyView.
Abstract We estimate the price impact of very nearby concurrently listed properties in the Sydney housing market and assess their competition effects. We apply a hedonic model with spatiotemporal effects regularized via a graph Laplacian prior at the month‐by‐SA2 regional level to seven SA4 subregions of metropolitan Sydney. The model structure enables
