It is difficult to adapt traditional screw motors with rubber stators the high-temperature and high-pressure conditions in ultra-deep wells, where age, deform carbonize, resulting motor failure. In this study, goal develop volumetric power drilling tools that can be used drill at depths of 10,000 m. To meet goal, an all-metal applied wells designed, then its deformation structural design are st...

The semi-micro method for interferon assay was based on quantitation of inhibition of cytopathic effects in 6-mm wells. Cultures were exposed to interferon dilutions, challenged with vesicular stomatitis virus, and stained with methylrosanaline chloride. The bound dye was then eluted and measured colorimetrically. The method was more sensitive than the plaque-inhibition method and was extremely...

A semi-micromethod is described for characterizing anaerobic bacteria by substrate utilization. Small volumes of individual substrates were placed in the wells of plastic microtiter trays. When heavy inocula and a colorimetric indicator were used, complete results were available after 30 h of incubation. Microtiter trays containing a range of substrates can be stored at -20 degrees C. The metho...

Our aim is to analyze the various energy functionals appearing in the physics literature and describing the behavior of a Bose-Einstein condensate in an optical lattice. We want to justify the use of some reduced models. For that purpose, we will use the semi-classical analysis developed for linear problems related to the Schrödinger operator with periodic potential or multiple wells potentials...

Intervalley scattering of hot electrons during high-field transport in transverse-field photorefractive quantum wells induces a nonlocal optical response in which photoinduced changes in the refractive index are spatially shifted relative to the optical stimulus, providing an avenue for optical gain. We demonstrate that the onset of the photorefractive phase shift coincides with the onset of ve...

Photoluminescence studies of neutral and charged excitons in modulation doped GaAs/Al0.3Ga0.7As quantum wells are performed as functions of applied pressure, temperature, and excitation power and frequency. Varying both pressure and incident power allows sensitive selection of the different exciton transitions. The G±X crossover in the barriers at 7 to 9 kbar accelerates photo-pumping of electr...

In many applications the process of generating label information is expensive and time consuming. We present a new method that combines active and semi-supervised deep learning to achieve high generalization performance from a deep convolutional neural network with as few known labels as possible. In a setting where a small amount of labeled data as well as a large amount of unlabeled data is a...

Semi-supervised clustering is an very important topic in machine learning and computer vision. The key challenge of this problem is how to learn a metric, such that the instances sharing the same label are more likely close to each other on the embedded space. However, little attention has been paid to learn better representations when the data lie on non-linear manifold. Fortunately, deep lear...

Verification determines whether two samples belong to the same class or not, and has important applications such as face and fingerprint verification, where thousands or millions of categories are present but each category has scarce labeled examples, presenting two major challenges for existing deep learning models. We propose a deep semisupervised model named SEmi-supervised VErification Netw...
