Despite intensive research, the mechanism determining terahertz (THz) emission of ferromagnetic (FM) metallic monolayers remains elusive. Here, we report on results a systematic investigation THz generated by pumping Ni80Fe20 Al2O3 substrates with femtosecond laser. We found solid evidence that is dominated anomalous Nernst effect (ANE), in which transient spin-polarized charge current can be i...

Almost two decades have passed since French and American trials evaluated the use of spinal opioids during labor and since European randomized trials compared conventional epidural analgesia with combined spinal epidural (CSE) analgesia. CSE analgesia has gained worldwide acceptance and is becoming increasingly popular for labor pain relief. Obstetric anesthetists are divided when questioned on...

The Kuratowski–Dugundji theorem that a metrizable space is an absolute (neighborhood) extensor in dimension n iff it is LCn−1&Cn−1 (resp., LCn−1) is extended to a class of non-metrizable absolute (neighborhood) extensors in dimension n. On this base, several facts concerning metrizable extensors are established for non-metrizable ones.

Although molecular research has contributed significantly to our knowledge of familial neurohypophyseal diabetes insipidus (FNDI) for more than a decade, the genetic background and the pathogenesis still is not understood fully. Here we provide a review of the genetic basis of FNDI, present recent progress in the understanding of the molecular mechanisms underlying its development, and survey d...

A scannable laser beam is used to generate local thermal gradients in metallic (Co2FeAl) or insulating (Y3Fe5O12) ferromagnetic thin films. We study the resulting local charge and spin currents that arise due to the anomalous Nernst effect (ANE) and the spin Seebeck effect (SSE), respectively. In the local ANE experiments, we detect the voltage in the Co2FeAl thin film plane as a function of th...

We report the anomalous Nernst effect (ANE) in polycrystalline metallic perovskite Pr0.5Sr0.5CoO3. The transverse Seebeck coefficient (Sxy) was measured at selected temperatures for magnetic fields up to H = 50 kOe and also as a function of temperature two (H 2 10 kOe). While Sxy increases linearly with above Curie (TC ∼ 229 K), it changes non-linearly low ferromagnetic state exhibits hysteresi...

The effect of pig slurry fertilization on tWQ olive (Olea europaea L. ev. Empeltre) groves has becn studied for ane season. The dosage of landsprayed slurry was 15 and 30 m3hafor a non-irrigatcd olive grove, which was in a bearing year and 30 and 60 m3hat fUT an irrigated grovc in a non-beaTing year. The macronutrient seasonal trend, both young (Iess than ayear old) and old (older than ane ycar...

Features derived from the trispectra of DFT magnitude slices are used for multi-font digit recognition. These features are insensitive to translation, rotation, or scaling of the input. They are also robust to noise. Classication accuracy tests were conducted on a common data base of 256256 pixel bilevel images of digits in 9 fonts. Randomly rotated and translated noisy versions were used for t...
