Прогнозирование геологической среды земной коры по материалам ГСЗ и петрофизического термобарического исследования минерального вещества

Some features of methodical means of petrovelocity thermobaric modeling have been considered. An example of the construction of a deep petrovelocity model of a crust part of the Ukrainian Shield is given and analysed

A mathematical formalism for the Kondo effect in WZW branes

In this paper, we show how to adapt our rigorous mathematical formalism for closed/open conformal field theory so that it captures the known physical theory of branes in the WZW model. This includes a mathematically precise approach to the Kondo effect, which is an example of evolution of one conformally invariant boundary condition into another through boundary conditions which can break conformal invariance, and a proposed mathematical statement of the Kondo effect conjecture. We also review some of the known physical results on WZW boundary conditions from a mathematical perspective.Comment: Added explanations of the settings and main result

Dynamics of long-range order in an exciton-polariton condensate

We report on time resolved measurements of the first order spatial coherence in an exciton polariton Bose-Einstein condensate. Long range spatial coherence is found to set in right at the onset of stimulated scattering, on a picosecond time scale. The coherence reaches its maximum value after the population and decays slower, staying up to a few hundreds of picoseconds. This behavior can be qualitatively reproduced, using a stochastic classical field model describing interaction between the polariton condensate and the exciton reservoir within a disordered potential.Comment: 7 pages, 4 figure

Economic Analysis of Increased Levels of Intramuscular Fat in Pork: Producer and Industry Opportunities

Ultrasound technology is available for accurately measuring intramuscular fat (IMF) in live pigs. This report provides information on the costs for pig producers and processors to implement this technology and what consumers are willing to pay for pork with improved levels of intramuscular fat. About half the participants in the willingness to pay study preferred the high IMF chop. They paid a premium of 25 percent over the low IMF chop.ultrasound technology, measure intramuscular fat live pigs, pig producer cost, pig processor costs, consumer willingness to pay, Agribusiness, Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Farm Management, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries, Marketing,

Synchronized and Desynchronized Phases of Exciton-Polariton Condensates in the Presence of Disorder

Condensation of exciton-polaritons in semiconductor microcavities takes place despite in plane disorder. Below the critical density the inhomogeneity of the potential seen by the polaritons strongly limits the spatial extension of the ground state. Above the critical density, in presence of weak disorder, this limitation is spontaneously overcome by the non linear interaction, resulting in an extended synchronized phase. This mechanism is clearly evidenced by spatial and spectral studies, coupled to interferometric measurements. In case of strong disorder, several non phase-locked (independent) condensates can be evidenced. The transition from synchronized phase to desynchronized phase is addressed considering multiple realizations of the disorder.Comment: 11 pages, 4 figures,corrected typos, added figure

Comparative study between AZERTY-type and K- Hermes virtual keyboards dedicated to users with cerebral palsy

International audienceThe aim of this paper is to compare two virtual keyboards for people with cerebral palsy; many of these users have difficulty performing actions using their upper limbs due to large numbers of unwanted movements. The first is a classical QWERTY type keyboard, called Clavicom NG. The second is the K-Hermes proposed in this paper. K-Hermes is a reduced and monotape keyboard; its entry principles are inspired by the T9 keyboard. The aim of the experiment is to demonstrate the reduced effort and increased speed of typing with the keyboard suggested for people with Cerebral Palsy
