SOME school people are ignoring the existence of teaching machines. Some are probably waiting impatiently for communication experts, psychologists, philanthropists and others to design and install perfectly operating machine in struction in their schools. However, most educational leaders are demanding thor ough study first and much subsequent research in school settings to ascertain the best u...

Th is work compares the polyphenolic compounds content in the in vitro shoot cultures of Hypericum rumeliacum, H. tetrapterum and in the hypericin non-producing H. calycinum, which are characteristic for the Balkan fl ora. In addition, the impact of diff erent vitamin supplementation to culture medium on secondary metabolites is discussed. Th ough Gamborg’s vitamins supplementation improved gro...

The paradigm for Eurisko’s exploration is a loop in which it. generat,es a new device configuration, computes its I/O behavior, tries to “parse” this into a functionality it already knows about and can use, and then evaluates the results In the first experiment, this loop took place at the level of charged carriers moving under the effects of electric fields thl ough abutted regions of doped an...

work was supported by NIH NCRR Grant No. 5P41RR012553. Abstract— The influence of brain tissue conductivity magnetoencephalography (MEG) has been largely nown. We compared the normal component of the netic field calculated at 61 detectors and the localization racy of 9 different realistic head finite element method ) models containing various gray and white matter uctivities to the results obta...

Since its inception, colonoscopy has evolved to become the cornerstone for colorectal imaging. The increasing indications for endoscopic evaluation and potential therapeutic intervention parallels technological advances and the expanding diagnostic and thera‐ peutic capabilities of colonoscopy. The diagnostic and therapeutic yield of colonoscopy is highly user dependent. Thus, it is essential f...

Model compensation techniques for noise-robust speech recognition approximate the corrupted speech distribution. is work introduces a sampling method that, given speech and noise distributions and a mismatch function, in the limit calculates the corrupted speech likelihood exactly. For this, it transforms the integral in the likelihood expression, and then applies sequential importance resampli...

ownloade ough cancer-associated fibroblasts (CAF) are key determinants in the malignant progression of cancer, unctional contribution to this process is still unclear. Analysis of the mutual interplay between prostate oma cells and CAFs revealed a mandatory role of carcinoma-derived interleukin-6 in fibroblast activaturn, activated fibroblasts through secretion of metalloproteinases elicit in c...

The pape~ aims to p~esent a CASE system which is an integ~ated compute~ aided tool so-called RUBIS, fo~ designing and p~ototyping Info~mation Systems. RUBIS is o~ganized a~ound the R-schema (RUBIS-schema), which is a decla~ative specification of the Info~mation System (IS) content, based on a conceptual model which emphasizes equally the IS st~uctu~e and behaviou~. Afte~ a b~ief ove~view of the...

We explore how a frozen background metric affects the mechanical properties of planar membranes with a shear modulus. We focus on a special class of "warped membranes" with a preferred random height profile characterized by random Gaussian variables h(q) in Fourier space with zero mean and variance <|h(q)|(2)>~q(-d(h)) and show that in the linear response regime the mechanical properties depend...

This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...
