Carnosine Declines with Age Carnosine (not to be confused with L-carnitine) is found in highest concentrations in long-lived tissues such as skeletal muscle, cardiac muscle and brain.1 Muscle carnosine levels in humans decline 63 percent from age 10 to 70 (Fig. 2).2 This marked reduction in muscle carnosine concentration may be a cause of the age-related decline in muscle mass, strength and fun...

Modelling of spin transport and spin dynamics, as a prerequisite for designing spintronic devices, is considered. Spin injection into a semiconductor under chargedepletion, chargeneutrality, and charge accumulation is investigated. The existence of amaximum spin current density in the bulk at a large spin current density at the interface in charge accumulation is related to the spin current at ...

This paper describes a mechanism for incorporating a mail guard mechanism together with automatic, mandatory, and fully transparent digital signatures and encryption for message traffic embedded into the operating system of individual network nodes. By intercepting all inbound and outbound network traffic and analyzing for pertinent information using generalized Büchi automata, the guard mechan...

An autosomal recessive juvenile-onset form of Parkinson's disease (AR-JP) is caused by loss-of-function mutations of the parkin gene, which encodes a ubiquitin-protein ligase. Three recent reports demonstrate that parkin can protect neurons from diverse cellular insults, including alpha-synuclein toxicity, proteasomal dysfunction, Pael-R accumulation, and kainate-induced excitotoxicity. These f...

The paper presents LinkGen, a synthetic linked data generator that can generate a large amount of RDF data based on certain statistical distribution. Data generation is platform independent, supports streaming mode and produces output in N-Triples and N-Quad format. Different sets of output can be generated using various configuration parameters and the outputs are reproducible. Unlike existing...

Black phosphorus (BP) has recently emerged as a promising semiconducting two-dimensional material. However, its viability is threatened by its instability in ambient conditions and by the significant decrease of its band gap in multilayers. We show that one could solve all the aforementioned problems by interfacing BP with hexagonal boron nitride (hBN). To this end, we simulate large, rotated h...

Assumptions of individual rationality and preference stability provide the foundation for a convenient and tractable modeling approach. While both of these assumptions have come under scrutiny in distinct literatures, the two lines of research remain disjointed. This study begins by explicitly linking the two literatures while providing insights into perhaps the central issue facing behavioral ...
