A burst search for gravitational waves from binary black holes
Compact binary coalescence (CBC) is one of the most promising sources of
gravitational waves. These sources are usually searched for with matched
filters which require accurate calculation of the GW waveforms and generation
of large template banks. We present a complementary search technique based on
algorithms used in un-modeled searches. Initially designed for detection of
un-modeled bursts, which can span a very large set of waveform morphologies,
the search algorithm presented here is constrained for targeted detection of
the smaller subset of CBC signals. The constraint is based on the assumption of
elliptical polarisation for signals received at the detector. We expect that
the algorithm is sensitive to CBC signals in a wide range of masses, mass
ratios, and spin parameters. In preparation for the analysis of data from the
fifth LIGO-Virgo science run (S5), we performed preliminary studies of the
algorithm on test data. We present the sensitivity of the search to different
types of simulated CBC waveforms. Also, we discuss how to extend the results of
the test run into a search over all of the current LIGO-Virgo data set.Comment: 12 pages, 4 figures, 2 tables, submitted for publication in CQG in

New phase structure of the Nambu -- Jona - Lasinio model at nonzero chemical potential
It is shown that in the Nambu -- Jona - Lasinio model at nonzero chemical
potential there are two different massive phases with spontaneously broken
chiral symmetry. In one of them particle density is identically zero, in
another phase it is not equal to zero. The transition between phases is a phase
transition of the second order.Comment: 8 pages, LaTeX, no figures

However, to date it remains a kind of Β«terra incognitaΒ» for the world historical and philosophical thought. Hesychasm is a kind of Christian mystical worldview that is embodied in a certain spiritual practices that form the basis of Orthodox asceticism. Even half a century ago, history of philosophy left without attention of philosophical and theological teachings of the authors of the late antiquity and the early middle ages, be they Christian thinkers or the neoΒPlatonists. The era of postΒPlotins philosophers Neoplatonists or commentators on Aristotle considered as a period of decline of this philosophy and the time of the rise of irrationality. For the same reason it was considered that the system of Christian thinkers cannot and should not be subject to the historical and philosophical science. This fully relates Hesychasm. However, on the basis of works of the French philosopher P. Ado, the paper argues that philosophy in late antiquity when there is Hesychasm is first of all a way of life, and therefore Hesychasm can be considered as a specific philosophical school of Christian asceticism. The main modern method of historical and philosophical studies is the hermeneutical reconstruction of cultural meaning of the philosophical texts, however, Hesychasm cannot be reduced to the Β«amount of textsΒ» or rational philosophical discourses. When learning is impossible not to take into account the existing experience, what is behind the lyrics: the experience of the inner purification, Β«the noetic prayer, which often has verbal reflection. Therefore, along with the use of hermeneutic and semiotic principles of research work with the texts, there is a problem of the analysis of the experience of spiritual practices. This requires the use of the phenomenological methods of cognition of mystical experience. At the same time, a mystical experience should be based on religious dogma. On this basis, the paper argues that the main methodological principles of historical and philosophical studies of Hesychasm is the hermeneutical reconstruction mysticalΒphilosophical texts, phenomenological description mystical experience and reliance on theological and Church tradition as to streamline this experience. Thus, the specific methodology of the study of the traditions connected with the peculiarities of Hesychasm as a special type of practical philosophizing.
Exotic solutions in string theory
Solutions of classical string theory, correspondent to the world sheets,
mapped in Minkowsky space with a fold, are considered. Typical processes for
them are creation of strings from vacuum, their recombination and annihilation.
These solutions violate positiveness of square of mass and Regge condition. In
quantum string theory these solutions correspond to physical states |DDF>+|sp>
with non-zero spurious component.Comment: accepted in Il Nuovo Cimento A for publication in 199
Mitigation of Ar/K background for the GERDA Phase II experiment
Background coming from the Ar decay chain is considered to be one of
the most relevant for the GERDA experiment, which aims to search of the
neutrinoless double beta decay of Ge. The sensitivity strongly relies on
the absence of background around the Q-value of the decay. Background coming
from K, a progeny of Ar, can contribute to that background via
electrons from the continuous spectrum with an endpoint of 3.5 MeV. Research
and development on the suppression methods targeting this source of background
were performed at the low-background test facility LArGe. It was demonstrated
that by reducing K ion collection on the surfaces of the broad energy
germanium detectors in combination with pulse shape discrimination techniques
and an argon scintillation veto, it is possible to suppress the K
background by three orders of magnitude. This is sufficient for Phase II of the
GERDA experiment
A tapering window for time-domain templates and simulated signals in the detection of gravitational waves from coalescing compact binaries
Inspiral signals from binary black holes, in particular those with masses in
the range 10M_\odot \lsim M \lsim 1000 M_\odot, may last for only a few
cycles within a detector's most sensitive frequency band. The spectrum of a
square-windowed time-domain signal could contain unwanted power that can cause
problems in gravitational wave data analysis, particularly when the waveforms
are of short duration. There may be leakage of power into frequency bins where
no such power is expected, causing an excess of false alarms. We present a
method of tapering the time-domain waveforms that significantly reduces
unwanted leakage of power, leading to a spectrum that agrees very well with
that of a long duration signal. Our tapered window also decreases the false
alarms caused by instrumental and environmental transients that are picked up
by templates with spurious signal power. The suppression of background is an
important goal in noise-dominated searches and can lead to an improvement in
the detection efficiency of the search algorithms
