A photoplethysmography (PPG) sensor is a cost-effective and efficacious way of measuring health conditions such as heart rate, oxygen saturation, and respiration rate.In this work, we present a hybrid PPG sensor system working in a reflective mode with an optoelectronic module, i.e., the combination of an inorganic light-emitting diode (LED) and a
Abstract Despite advances in treatment regimens that comprise surgery, chemotherapy, and radiation, outcome of many brain tumors remains dismal, more so when they recur.The proximity of brain tumors to delicate neural structures often precludes complete surgical resection.Toxicity and long-term side effects of systemic therapy remain a concern.Nove

Abstract For conformal field theories, it is shown how the Ward identity corresponding to dilatation invariance arises in a Wilsonian setting.In so doing, several points which are opaque in textbook treatments are clarified.Exploiting the fact that the Exact Renormalization Group furnishes Cosmetic Bag a representation of the conformal algebra allo
