The feature selection characterized by relatively small sample size and extremely high dimensional feature space is common in many areas of contemporary statistics. The high dimensionality of the feature space causes serious difficulties: (i) the sample correlations between features become high even if the features are stochastically independent; (ii) the computation becomes intractable. These ...

In 2012, a survey was carried out in 8 French cities to study noise annoyance due to combined transportation noise sources. Both partial and total annoyances were measured. The current paper will first focus on partial noise annoyance due to railway traffic measured in 6 French cities. In order to predict annoyance due to single transportation noise sources, the European Commission recommends t...

Failure analysis challenges have increased as electronic circuit capability and complexity of integrated circuits evolve to higher densities and smaller feature sizes. Despite this evolution, “old school” tools can be effective in solving problems on both simple and complex devices. In particular, when Voltage Contrast (VC) and Electron Beam Induced Current (EBIC) are combined together results ...

We have studied the influence of misfit dislocations on hole accumulation in the base layer of an n-AlGaAs/p-GaAs/n-InGaAs heterojunction phototransistor ~HPT!. Spatially and temporally resolved cathodoluminescence ~CL! measurements reveal that variations in the hole accumulation is caused primarily by strain-induced defects which impede the transport of holes in the collector. The lifetime of ...

In a semiconductor either electrons or holes typically dominate as dictated by the concentration of ionized dopants, and the nomenclature is n type for electrons dominating and p type for holes. Minority carriers are therefore holes in n type and electrons in p type. Electron-hole pair generation is a local disturbance from the equilibrium concentration. As electron hole pairs are formed, the d...

The basic stages of development of the theory of superconductivity are traced. Despite of remarkable successes of theory, the physical explanation of the phenomenon of superconductivity-of the not fading electrical current in dissipative medium-is not exists until now. In the present paper on the basis of works (Klimontovich, 1990abc, 1999) the physical explanations of this phenomenon is consid...

Inversion in conductivity type of GaSb from pto nhas been observed as a result of argon ion beam milling. Electron beam induced current ~EBIC! measurements have been employed for detecting the type conversion. Enhancement in the luminescence intensity is seen after ion beam treatment. The type conversion is proposed to occur due to a combined effect of generation of native donors and gettering ...

Eye opening, a natural and timed event during animal development, influences cortical circuit assembly and maturation; yet, little is known about its precise effect on inhibitory synaptic connections. Here, we show that coinciding with eye opening, the strength of unitary inhibitory postsynaptic currents (uIPSCs) from somatostatin-expressing interneurons (Sst-INs) to nearby excitatory neurons, ...
