potassium bromide (kbr), an old antiepileptic agent, is illegally used in pharmaceutical or food industries to improve the product appearance. kbr has been proven to influence several pathways which are important in memory formation. therefore, the present study aimed to evaluate the effect of kbr on spatial working memory using object recognition task (ort). rats received a single dose of kbr ...

The knowledge-based rational decision model (KBR-model) offers an approach to rational decision making in a non-probabilistic setting, e.g., in perfect information games with deterministic payoffs. The KBR-model uses standard game-theoretical assumptions and suggests following a strategy yielding the highest payoff which the agent can secure to the best of his knowledge. In this report, we prov...

Kernel Based Regression (KBR) minimizes a convex risk over a possibly infinite dimensional reproducing kernel Hilbert space. Recently it was shown that KBR with a least squares loss function may have some undesirable properties from a robustness point of view: even very small amounts of outliers can dramatically affect the estimates. KBR with other loss functions is more robust, but often gives...

The use of KBr pellets as an interference-free matrix for performing time-resolved infrared (TR-IR) measurements on samples in their crystalline state is described and demonstrated. Step-scan Fourier transform infrared time-resolved spectroscopy (S2FT-IR TRS) is used to measure the infrared (IR) absorption difference ( D A, excited state minus ground state) spectra of the long-lived chargetrans...

This paper presents some theoretical convergence characteristics of Keep-Best Reproduction (KBR), a selection strategy for genetic algorithms (GAs). We have previously introduced KBR and reported encouraging results in the traveling salesman domain (Wie98a) where KBR was compared with the standard replacement strategy of replacing the two parents by their two children (STDS). Here we demonstrat...

Background—The Na/Ca exchange (NCX) extrudes Ca from cardiac myocytes, but it can also mediate Ca influx, load the sarcoplasmic reticulum with Ca, and trigger Ca release from the sarcoplasmic reticulum. In ischemia/ reperfusion or digitalis toxicity, increased levels of intracellular [Na] ([Na]i) may raise levels of intracellular [Ca ] ([Ca]i) via NCX, leading to cell injury and arrhythmia. Met...

The photoemissive stability of as-deposited and heat-treated CsI, KI and KBr evaporated thin "lms under UV radiation is examined in this paper. After the deposition, some photocathodes were annealed for several hours at 903C in vacuum and their performance was then compared to the performance of non-heated samples. We observed that the post-evaporation thermal treatment not only increases the p...

Nonparametric inference techniques provide promising tools for probabilistic reasoning in high-dimensional nonlinear systems. Most of these techniques embed distributions into reproducing kernel Hilbert spaces (RKHS) and rely on the kernel Bayes’ rule (KBR) to manipulate the embeddings. However, the computational demands of the KBR scale poorly with the number of samples and the KBR often suffe...

BACKGROUND The Na(+)/Ca(2+) exchange (NCX) extrudes Ca(2+) from cardiac myocytes, but it can also mediate Ca(2+) influx, load the sarcoplasmic reticulum with Ca(2+), and trigger Ca(2+) release from the sarcoplasmic reticulum. In ischemia/reperfusion or digitalis toxicity, increased levels of intracellular [Na(+)] ([Na(+)](i)) may raise levels of intracellular [Ca(2+)] ([Ca(2+)](i)) via NCX, lea...

BACKGROUND Right heart function is the key determinant of symptoms and prognosis in pulmonary hypertension (PH), but the right ventricle has a complex geometry that is challenging to quantify by two-dimensional (2D) echocardiography. A novel 2D echocardiographic technique for right ventricular (RV) quantitation involves knowledge-based reconstruction (KBR), a hybrid of 2D echocardiography-acqui...
