Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

In the Eye of the Deceiver: Analyzing Eye Movements as a Cue to Deception

Journal of Imaging, 2018
Deceit occurs in daily life and, even from an early age, children can successfully deceive their parents. Therefore, numerous book and psychological studies have been published to help people decipher the facial cues to deceit.

Iris Template Protection Based on Local Ranking [PDF]

Security and Communication Networks, 2018
Biometrics have been widely studied in recent years, and they are increasingly employed in real-world applications. Meanwhile, a number of potential threats to the privacy of biometric data arise. Iris template protection demands that the privacy of iris data should be protected when performing iris recognition.

A Metal‐Free Carbon Monoxide Prodrug Suppresses Metastasis of Pancreatic and Breast Cancer

Advanced Science, EarlyView.
A metal‐free carbon monoxide (CO) prodrug, CO‐116, delivers controlled systemic CO without inhalation. CO suppresses the HRG1–heme axis, reducing intracellular heme availability. Attenuation of this pathway inhibits metastatic progression in pancreatic and triple‐negative breast cancer models.

Local intensity variation analysis for iris recognition [PDF]

Pattern Recognition, 2004
As all emerging biometric for human identification, iris recognition has received increasing attention in recent years. This paper makes an attempt to reflect shape information of the iris by analyzing local intensity variations of an iris image. In Our framework, a set of one-dimensional (1D) intensity signals is constructed to contain the most ...
