Data privacy is a major concern when accessing and processing sensitive medical data. A promising approach among privacy-preserving techniques homomorphic encryption (HE), which allows for computations to be performed on encrypted Currently, HE still faces practical limitations related high computational complexity, noise accumulation, sole applicability the at bit or small integer values level...

We present a simple and yet effective interpolation-based regularization technique, aiming to improve the generalization of Graph Neural Networks (GNNs) on supervised graph classification. leverage Mixup, an regularizer for vision, where random sample pairs their labels are interpolated create synthetic images training. Unlike with grid-like coordinates, graphs have arbitrary structure topology...

Biosensors allow the direct detection of molecular analytes, by associating a biological receptor with a transducer able to convert the analyte-receptor recognition event into a measurable signal. We review recent work aimed at developing synthetic fluorescent molecular sensors for a variety of analytes, based on peptidic receptors labeled with environmentally sensitive fluorophores. Fluorescen...

arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...

Solid-state lasers pumped by high-power two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs) were investigated. Both end-pumping and side-pumping schemes of Nd:YAG lasers with high power kW-class 808 nm VCSEL pump modules were implemented. For one application 10 mJ blue laser pulses were obtained from a frequencydoubled actively Q-switched VCSEL-array dual side-pumped Nd:Y...

Progressive coding is an important feature of compression schemes. Wavelet coders are well suited for this purpose because the wavelet coefficients can be naturally ordered according to decreasing importance. Progressive fractal coding is feasible, but it was proposed only for hybrid fractal-wavelet schemes. We introduce a progressive fractal image coder in the spatial domain. A Lagrange optimi...

Obesity is a term used to describe body weight that is much greater than what is considered healthy. It has become a serious public health problem. It affects 32.2% of the global population. The worldwide prevalence of obesity is 1.6 billion and is already reached epidemic proportions mostly in high income groups. Strategies involve general lifestyle modification includes healthy diet, maintain...

We study the mutual interference problem arising in the fast growing market of automotive radars. For the widely used frequency-modulated continuous waveform automotive radars, the major consequences of mutual interference are ghost targets and increased noise floor. The schemes of interference mitigation are then investigated, including adaptive signal processing in the time domain at receive ...

In the present study the combined therapeutic approach of using an isolated compound from a herb and an oral hypoglycemic drug in alloxan-induced diabetic mice is investigated. Herbal drugs can have beneficial effects in terms of reducing the dosage, side effects and duration of action of synthetic drugs. The results show that combined therapy with 4hydroxyisoleucine and pioglitazone is more be...
