Solar cells, also known as photovoltaic devices, are a class of renewable energy systems that can convert photons into electrons without the carbon dioxide emission. Short-wavelength, high-energy photons in the ultraviolet (UV) range can't be efficiently utilized by most solar cells because of the spectral mismatch. Luminescent downshifting is a...

Proteolysis of myofibrillar proteins in Pacific whiting surimi occurs when the 50-
70°C temperature range is reached during standard cooking procedures (e.g. 90°C for 15
min). This proteolytic activity results in the softening of surimi gels. Bovine plasma
protein (BPP) is the most effective of the food-grade inhibitors used to...

Soil organic carbon (SOC, kg C m-2) is an important component in evaluating global C stores. The nitrogen (TN, kg N m"2) cycle is closely linked to C and understanding its role is also important. Contents and distributions of SOC and TN in soil profiles, to 1-meter depth, were estimated...
It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...
DNA damage, if not repaired, can become a mutation. Mutation
accumulation is associated with initiation and progression of tumorigenesis. DNA
mismatch repair (MMR) is required for maintaining genetic stability by repairing

While riding bicycles has been promoted for its health, economic, and environmental benefits, it also complements other modes to complete a safe, efficient, and reliable transportation system. However, the dramatic increase of bicycle usage in the U.S. is accompanied by a growth of bicycle crashes. The U.S. Department of Transportation,...
The national average life expectancy for houseless individuals in the United States is forty seven years, which is thirty years lower than the overall average. I argue that this disproportionately short life expectancy of the houseless is reflective of significant health inequities in the United States that disproportionately impact the...
What historical and political reality is reflected in the novels Gringo viejo and La frontera de cristal? What is revealed when the characters, plot, and setting of the novels are analyzed against research of the context of U.S.-Mexico relations? We begin to explore these questions by studying three periods crucial...
The study of differentiation of integrals has led to the study of maximal functions. In the development of harmonic analysis, the most powerful result connected with Lebesgue's theorem was that of the Hardy-Littlewood Maximal Theorem. This maximal theorem implies Lebesgue's theorem, and the maximal function and its variants have played...

drought stresses, its effect on chilling tolerance has not been examined. To evaluate
whether...
In poplar (Populus spp.) a 32-kilodalton bark storage protein (BSP) accumulates during the fall and winter, and is thought to be a major storage form of overwintering nitrogen. BSP is induced by short-day (SD) photoperiod, and under natural conditions BSP accumulation coincides with the induction of dormancy. Because BSP accumulates...
