High concentration photovoltaic thermal hybrids are expected to play an important role in meeting growing energy demands. When approaching concentrations over 1000 suns, a cooling system is needed maximise both the and electrical performance of multi-junction solar cell without producing excessive parasitic losses. This study develops novel simulation model provides in-depth understanding funct...

Metals usually appear shiny and reflect light, but even seemingly smooth mirrors can luminesce under photoexcitation, i.e. absorb and reemit light. Although this phenomenon has been known for almost 50 years, and plays a significant role in the interaction of light waves with plasmon modes of metallic nanostructures, given the inherent momentum mismatch between electrons and photons the microsc...

The kinetic model has been developed for disserting the efficiency of solar energy conversion as a function of light intensity. A comparison of theory with experimental results shows that the model provides a satisfactory agreement. We have estimated the essential parameters of photosynthetic systems (the size of the photosynthetic antenna, the rate of electron transport, the correlation betwee...

Background Multiple myeloma (MM) affects mainly the older population and is second most prevalent haematologic cancer. MM patients' unmet needs are diverse, arise at different stages, associated with greater psychological distress. This study examined psychometric properties of Short‐Form Survivor Unmet Needs Survey (SF‐SUNS) in Portuguese patients. Methods cross‐sectional included 213 The inte...

Necessary and sufficient conditions for the functional central limit theorem for a double array of random variables are sought. It is argued that this is a martingale problem only if the variables truncated at some fixed point c are asymptotically a martingale difference array. Under this hypothesis, necessary and sufficient conditions for convergence in distribution to a Brownian motion are ob...
