DĂ©jĂ vu phenomenon-related EEG pattern. Case report
AbstractBackgroundDĂ©jĂ vu (DV, from French dĂ©jĂ vu â âalready seenâ) is an aberration of psychic activity associated with transitory erroneous perception of novel circumstances, objects, or people as already known.ObjectiveThis study aimed to record the EEG pattern of dĂ©jĂ vu.MethodsThe subjects participated in a survey concerning dĂ©jĂ vu characteristics and underwent ambulatory EEG monitoring (12â16h).ResultsIn patients with epilepsy, DV episodes began with polyspike activity in the right temporal lobe region and, in some cases, ended with slow-wave thetaâdelta activity over the right hemisphere. There were no epileptic discharges in healthy respondents during DV.ConclusionTwo types of dĂ©jĂ vu are suggested to exist: âpathological-epilepticâ dĂ©jĂ vu, characteristic of patients with epilepsy and equivalent to an epileptic seizure, and ânonpathological-nonepilepticâ dĂ©jĂ vu, which is characteristic of healthy people and psychological phenomenon
Novel amphiphilic compounds effectively inactivate the vaccinia virus
AbstractRecent studies demonstrated the ability of artificial ribonucleases (aRNases, small organic RNA cleaving compounds) to inactivate RNA-viruses via the synergetic effect of viral RNA cleavage and disruption of viral envelope [1,2]. Herein, we describe the antiviral activity of aRNases against DNA-containing vaccinia virus: screening of aRNases of various structures revealed that amphiphilic compounds built of positively charged 1,4-diazabicyclo[2.2.2] octane substituted at the bridge nitrogen atoms with aliphatic residues efficiently inactivate this virus. The first stage was the destruction of viral membrane and structure of surface proteins (electron microscopy data). Thus, 1,4-diazabicyclo[2.2.2] octane-based aRNases are novel universal agents inactivating both RNA- and DNA-containing viruses
Structural Evolution and Phase Transformation in Nanoquasicrystalline Al-Fe-Cr Alloy: DSC Analysis
Kinetic parameters for microstructural evolution and phase transformation in water atomized Al-Fe-Cr
based alloy with nominal composition Al94Fe3Cr3 have been examined by means of developed precise method
of DSC technique and confirmed by the results of XRD analysis. Two exothermic reactions including that
with a maximum at 380 â 400 degrees Celsius has been ascribed to dislocation reorganisation and recrystallisation process within the Al matrix although the main exothermic reaction with a maximum around 540 degrees Celsius arose
from decomposition of icosahedral quasicrystalline particles and simultaneous formation of the metastable
Al6Fe phase and more stable crystalline particles compositionally corresponded to the O-Al13Cr2 and
O-Al13Fe4 phases. Activation energy for the main exothermic reaction has been found to be roughly
about 53.1 kJ mol-1 which is significantly smaller than that for the bulk diffusion of either iron or chromium atoms in aluminium and very close to that for the vacancy migration.

Thin film nanopores (V, 10Ti)NxHy hydrogen storages
This scientific paper delves into the findings of the investigation carried out to determine the adsorption and electrophysical characteristics of nanoporous (V, 10 at.% Ti)Nx films obtained using the ion beam-assisted deposition technique (IBAD). It has been shown that these films can accumulate more than 7 wt.% hydrogen at a relatively low pressure of 0,5 MPa. One part of it is accumulated in the grain boundaries and pores but another one forms the hydride phase. A complete release of hydrogen occurs at a temperature of 250 °C. During the hydrogen desorption the specific resistivity of (V, 10Ti)NxHy films is roughly increased by a factor of 10â·.ĐŃĐžĐČĐ”ĐŽĐ”ĐœŃ ŃДзŃĐ»ŃŃĐ°ŃŃ ĐžŃŃĐ»Đ”ĐŽĐŸĐČĐ°ĐœĐžĐč Đ°ĐŽŃĐŸŃбŃĐžĐŸĐœĐœŃŃ

Formation of initial changes in hemodynamics and fluid compartments in high surgical risk patients under the influence of acute abdominal pathology
Among the main factors of pathological changes that accompany acute abdominal pathology are the inflammatory process of the peritoneum and fluid deficiency due to its pathological losses. The aim of our study was to analyze the initial state of fluid compartments of the body and hemodynamics in high surgical risk patients with acute surgical abdominal pathology. There were examined 157 patients with acute abdominal pathology who underwent emergency laparotomy. The presence and severity of fluid deficiency were determined clinically by tissue hydrophilicity test by P.I. Shelestiuk, biochemically â by assessing the levels of hematocrit, hemoglobin, erythrocytes, blood electrolytes, vasopressin (antidiuretic hormone (ADH)) and brain natriuretic propeptide (proBNP), as well as the mean erythrocyte volume and plasma osmolarity. Variables of fluid compartments of the body and central hemodynamics were studied using the non-invasive bioimpedancemetry. Based on the values of oxygen concentration in arterial and venous blood, total oxygen consumption (VO 2 ) and delivery of oxygen (DO 2 ), oxygen extraction ratio (O 2 ER) were calculated. The detected changes indicate intravascular fluid deficiency and concomitant hemoconcentration with normal electrolytes levels and plasma osmolarity. In patients with high surgical risk and moderate dehydration according to P.I. Shelestiuk, urgent surgical pathology of the abdominal cavity reduces extracellular fluid volume by 19.1% (p=0.019) of the reference by reducing the volume of the interstitium and intravascular fluid respectively by 20.7% (p=0.002) and 16.3% (p=0.001) of regional values, which forms in patients a state of "volume depletion" of moderate severity. This is accompanied by an increase in the ADH concentration by 16.7% (p=0.041) above reference and normal proBNP levels. Stroke volume decreases by 28.8% (p=0.021) against tachycardia (increase in heart rate by 39.7% (p=0.001) above normal) and vascular spasm (increase in systemic vascular resistance by 86.9% (p=0.001) above reference), which supports the normodynamic type of blood circulation (cardiac index â 3.2 (0.4) l/min/m 2 ) with the decrease in stroke index and peripheral perfusion index by 41.3% (p=0.002) and 55.2% (p=0.002) from reference, respectively. DO 2 decreases by 11.1% (p=0.011) from reference with VO 2 increased by 16.3% (p=0.004) above reference, which leads to a decrease in oxygen utilization by 7.2% (p=0.041) from reference.

Unconstrained Hamiltonian Formulation of SU(2) Gluodynamics
SU(2) Yang-Mills field theory is considered in the framework of the
generalized Hamiltonian approach and the equivalent unconstrained system is
obtained using the method of Hamiltonian reduction. A canonical transformation
to a set of adapted coordinates is performed in terms of which the
Abelianization of the Gauss law constraints reduces to an algebraic operation
and the pure gauge degrees of freedom drop out from the Hamiltonian after
projection onto the constraint shell. For the remaining gauge invariant fields
two representations are introduced where the three fields which transform as
scalars under spatial rotations are separated from the three rotational fields.
An effective low energy nonlinear sigma model type Lagrangian is derived which
out of the six physical fields involves only one of the three scalar fields and
two rotational fields summarized in a unit vector. Its possible relation to the
effective Lagrangian proposed recently by Faddeev and Niemi is discussed.
Finally the unconstrained analog of the well-known nonnormalizable groundstate
wave functional which solves the Schr\"odinger equation with zero energy is
given and analysed in the strong coupling limit.Comment: 20 pages REVTEX, no figures; final version to appear in Phys. Rev. D;

The COMPASS Experiment at CERN
The COMPASS experiment makes use of the CERN SPS high-intensitymuon and
hadron beams for the investigation of the nucleon spin structure and the
spectroscopy of hadrons. One or more outgoing particles are detected in
coincidence with the incoming muon or hadron. A large polarized target inside a
superconducting solenoid is used for the measurements with the muon beam.
Outgoing particles are detected by a two-stage, large angle and large momentum
range spectrometer. The setup is built using several types of tracking
detectors, according to the expected incident rate, required space resolution
and the solid angle to be covered. Particle identification is achieved using a
RICH counter and both hadron and electromagnetic calorimeters. The setup has
been successfully operated from 2002 onwards using a muon beam. Data with a
hadron beam were also collected in 2004. This article describes the main
features and performances of the spectrometer in 2004; a short summary of the
2006 upgrade is also given.Comment: 84 papes, 74 figure
Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment
This paper describes an analysis of the angular distribution of W->enu and
W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with
the ATLAS detector at the LHC in 2010, corresponding to an integrated
luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and
the missing transverse energy, the W decay angular distribution projected onto
the transverse plane is obtained and analysed in terms of helicity fractions
f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV
and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw
> 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour,
are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017
+/- 0.030, where the first uncertainties are statistical, and the second
include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables,
