The problem of calibrating a Cherenkov water detector (CWD) and the possibilities for its use based on the example of the CWD NEVOD are discussed. Results of the calibration of quasi-spherical modules in water volume by means of vertical muons selected by scintillation telescopes and compared to the results from measurements performed at test facilities are presented. 相似文献

Based on the developed quantum microscopic theory, the interaction of weak electromagnetic radiation with dense ultracold
atomic clouds is described in detail. The differential and total cooperative scattering cross sections are calculated for
monochromatic radiation as particular examples of application of the general theory. The angular, spectral, and polarization
properties of scattered light are determined. The dependence of these quantities on the sample size and concentration of atoms
is studied and the influence of collective effects is analyzed. 相似文献

Here we show that the surface of human cervical epithelial cells demonstrates substantially different fractal behavior when the cell becomes cancerous. Analyzing the adhesion maps of individual cervical cells, which were obtained using the atomic force microscopy operating in the HarmoniX mode, we found that cancerous cells demonstrate simple fractal behavior, whereas normal cells can only be approximated at best as multifractal. Tested on ~300 cells collected from 12 humans, the fractal dimensionality of cancerous cells is found to be unambiguously higher than that for normal cells. 相似文献

This paper reports on the results of investigations of the thermal properties and thermal conductivity of single crystals of homogeneous solid solutions Fe x Mn1 ? x S with a cubic NaCl structure, which have been prepared by the cation substitution for divalent manganese ions in manganese monosulfide. It has been revealed that the heat capacity and thermal conductivity exhibit anomalies in the range of the magnetic transition. The cation substitution is accompanied by an increase in the phase transition temperature. 相似文献

Heterostructures of the “strained Ge film/artificial InGaAs layer/GaAs substrate” type have been grown by molecular beam epitaxy.
A specific feature of these structures is that the plastically relaxed (buffer) InGaAs layer has the density of threading
dislocations on a level of 105–106 cm−2. These dislocations penetrate into the strained Ge layer to become sources of both 60° and 90° (edge) misfit dislocations
(MDs). Using the transmission electron microscopy, both MD types have been found at the Ge/InGaAs interface. It has been shown
that the presence of threading dislocations inherited from the buffer layer in a tensile-strained Ge film favors the formation
of edge dislocations at the Ge/InGaAs interface even in the case of small elastic deformations in the strained film. Possible
mechanisms of the formation of edge MDs have been considered, including (i) accidental collision of complementary parallel
60° MDs propagating in the mirror-tilted {111} planes, (ii) induced nucleation of a second 60° MD and its interaction with
the primary 60° MD, and (iii) interaction of two complementary MDs after a cross-slip of one of them. Calculations have demonstrated
that a critical layer thickness (h
c
) for the appearance of edge MDs is considerably smaller than h
c
for 60° MDs. 相似文献

The initiation and propagation of low-velocity detonation in ammonium perchlorate (AP)-aluminum-nitromethane (NM) mixtures
with Al: AP ratios of 1: 1 to 2.5: 1 and porosities from 40 (10 wt % HM) to 0% (40 wt % NM) in strong steel shells (in the
air) and plastic shells submerged in water are experimentally studied. The optimum contents of the components that provide
reliable initiation of steady detonation (at velocities from 2 to 5 km/s) by weak explosive sources in mixtures with an Al:
AP ratio of 1: 1 and above are determined. The selected mixtures reproducibly detonate in plastic shells surrounded by a 30-cm-thick
layer of water at velocities somewhat lower than in strong steel shells in the air. 相似文献

An experimental study of the characteristics of the explosion of mixtures of ammonium perchlorate, aluminum, and nitromethane
with a large excess of aluminum (1.45 to 1.66 g/cm3 in density) confined in plastic enclosures and immersed in small elastic-wall reservoirs with water is conducted. It is shown
that composite charges, 20 mm in diameter, surrounded by a water layer of thickness 20–30 cm and detonate in a nonideal detonation
mode. High-speed cinematography records show the possibility of the intense mixing of the detonation products with the surrounding
water and of the burning of excess aluminum particles in a heterogeneous cloud. The time scales of the development of secondary
energy release by burning of aluminum particles in water are estimated. The possibility of controlling the characteristics
of the pressure waves generated by the explosion, for example, by means of a preliminary bubbling of the water with air near
the charge, is demonstrated. 相似文献

Slow-light effects induced by stimulated Raman scattering in polymer waveguides on a printed circuit board are shown to enable a widely tunable delay of broadband optical signals, suggesting an advantageous platform for optical information processing and ultrafast optical waveform transformation. 相似文献
