Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

A Cationic Supramolecule With Potent Antifungal Activity, Single‐Species Selectivity, and Strong Synergy With Echinocandins

Advanced Science, EarlyView.
We introduce a new membrane‐active antifungal design, Gua‐SMACS‐16, that exhibits high potency and single‐species selectivity for C. tropicalis while sparing other close species in the Candida genus. Moreover, when combining with caspofungin, a clinical antifungal drug inhibiting 1,3‐β‐glucan synthase, they exhibit ultra‐strong synergy across a panel ...

Optimal opportunistic sensing in cognitive radio networks

IET Communications, 2012
The authors are interested in evaluating the performance of a cognitive radio network composed of secondary and primary mobiles, and look for optimising the decision process of the secondary mobiles when they have to choose between licensed or unlicensed channels.

Optimality of Multichannel Myopic Sensing in the Presence of Sensing Error for Opportunistic Spectrum Access [PDF]

Journal of Applied Mathematics, 2013
The optimization problem for the performance of opportunistic spectrum access is considered in this study. A user, with the limited sensing capacity, has opportunistic access to a communication system with multiple channels. The user can only choose several channels to sense and decides whether to access these channels based on the sensing information ...

PancDS in Real‐World Practice: A Prospective Multicenter Validation of a Clinical Decision‐Support System Bridging Experience Gaps in Pancreatic Lesion Diagnosis

Advanced Science, EarlyView.
A biomimetic artificial intelligence system, PancDS, has been developed to distinguish pancreatic ductal adenocarcinoma from mass‐forming pancreatitis by adaptively integrating clinical data, radiomics, and deep learning features. Validated across multicenter, reader‐study, and prospective settings, PancDS improves diagnostic accuracy, particularly for

On Optimality of Myopic Sensing Policy with Imperfect Sensing in Multi-Channel Opportunistic Access [PDF]

IEEE Transactions on Communications, 2013
We consider the channel access problem under imperfect sensing of channel state in a multi-channel opportunistic communication system, where the state of each channel evolves as an independent and identically distributed Markov process. The considered problem can be cast into a restless multi-armed bandit (RMAB) problem that is of fundamental ...

Synthetic MRI Neuroimaging Correlates of Frailty: Correlations Between Frailty Scales and Brain Structural Integrity

AGING MEDICINE, EarlyView.
Frailty was associated with decreased gray and white matter brain volumes in older adults. Synthetic MRI further revealed relaxometry alterations correlated with frailty severity across multiple clinical scales. ABSTRACT Objectives Frailty, a common condition in the elderly, is characterized by a decline in physiological reserves and an increased ...

Effect of Lactulose on the Intestinal Flora of Elderly Constipation Patients With Chronic Renal Insufficiency

AGING MEDICINE, EarlyView.
This study investigates the regulatory effects of lactulose and polyethylene glycol (PEG) on the composition of gut microbiota in elderly constipation patients with chronic renal insufficiency by comparing the changes in microbial abundance. Both lactulose and PEG significantly modulate the gut microbiota structure, though their specific mechanisms and

Distributed opportunistic sensing in mobile phone sensor networks [PDF]

2013 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops), 2013
The advantages of smartphones such as integrated sensors, programmability, scalability and cloud servers have enabled low-cost and efficient public safety applications. However, designing such applications has to face daunting challenges, for instance, short battery life, low computing capability and lacking memory.
