Performance of the WaveBurst algorithm on LIGO data
In this paper we describe the performance of the WaveBurst algorithm which
was designed for detection of gravitational wave bursts in interferometric
data. The performance of the algorithm was evaluated on the test data set
collected during the second LIGO Scientific run. We have measured the false
alarm rate of the algorithm as a function of the threshold and estimated its
detection efficiency for simulated burst waveforms.Comment: proceedings of GWDAW, 2003 conference, 13 pages, 6 figure

The aim of the study was to assess results of long-term treatment of chronic obstructive bronchitis (COB) patients performed by therapeutists trained according to the Federal programme on COPD.Treatment results of 151 COB patients (100 males and 51 females) were analyzed. The average age of the patients was 51.8Β±0.8 years. The long-term treatment was carried out in accordance to the algorithm of the basic therapy of COPD.The significant positive changes in the patientsβ clinical status were noted at the end of the 3rd week of the therapy: a cough frequency reduced in 96.7% of the patients and a dyspnoe severity decreased in 95.4% of them. The peak flow rate parameters improved reliably. Seventy three moderate to severe COB patients had received the basic medication during 12 months showed decreasing cough and dyspnoe seventy and improving peak flow rate parameters though these changes were less intensive than in the first 3 weeks of the treatment.So, the investigation demonstrated a possibility to inhibit the bronchial obstruction and COB clinical signs progression under the background of the long-term basic therapy.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ ΠΎΡΠ΅Π½ΠΈΡΡ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ Π΄Π»ΠΈΡΠ΅Π»ΡΠ½ΠΎΠ³ΠΎ Π»Π΅ΡΠ΅Π½ΠΈΡ Π±ΠΎΠ»ΡΠ½ΡΡ

Prospects for intermediate mass black hole binary searches with advanced gravitational-wave detectors
We estimated the sensitivity of the upcoming advanced, ground-based
gravitational-wave observatories (the upgraded LIGO and Virgo and the KAGRA
interferometers) to coalescing intermediate mass black hole binaries (IMBHB).
We added waveforms modeling the gravitational radiation emitted by IMBHBs to
detectors' simulated data and searched for the injected signals with the
coherent WaveBurst algorithm. The tested binary's parameter space covers
non-spinning IMBHBs with source-frame total masses between 50 and 1050
and mass ratios between and 1. We found that
advanced detectors could be sensitive to these systems up to a range of a few
Gpc. A theoretical model was adopted to estimate the expected observation
rates, yielding up to a few tens of events per year. Thus, our results indicate
that advanced detectors will have a reasonable chance to collect the first
direct evidence for intermediate mass black holes and open a new, intriguing
channel for probing the Universe over cosmological scales.Comment: 9 pages, 4 figures, corrected the name of one author (previously

Antithrombotic Therapy and the Nearest Forecast of Pulmonary Embolism in Rutine Clinical Practice (Data of the Regional Vascular Center of the Ryazan Region)
Aim. To perform the analysis of antithrombotic therapy and immediate prognosis in patients with pulmonary embolism (PE) in routine clinical practice.Materials and methods. During 13 months of follow-up (2018-2019) within the framework of the Russian SIRENA registry, the study included patients (n=103) with verified PE who were hospitalized at the regional vascular center.Β Main results. Thrombolytic therapy was performed in 63 patients (61.2% of the sample), of which 48 (76.2%) had no indications. In these cases, the most common reason for performance was the results of the PESI score (n=17) and/or a significant amount of damage to the pulmonary artery (n=10) and/or severe shortness of breath (n=3) and/or the presence of a thrombus in the right parts of the heart or deep veins of the lower extremities (n=2), in addition, in a number of medical records, the cause is indicated as βfor health reasonsβ (n=6) or there were no data (n=10). Patients who underwent thrombolysis had a larger volume of pulmonary lesions, more pronounced signs of respiratory failure and overload of the right heart, as well as a shorter duration of clinical manifestations. Anticoagulant therapy was used in 94.2% of cases, of which 90.3% of patients used parenteral forms at the start, then direct oral anticoagulants were mainly used, the frequency of warfarin prescription was only 5.8% of cases. Bleeding was registered in 19.4% of patients (significant β in 11.7%). PE recurrence after diagnosis and initiation of therapy was observed in 4 cases (3.9%). Hospital mortality was 9.7%. Predictors of poor prognosis were hospitalization with a different diagnosis (risk ratio [RR] 16.2; p=0.001), advanced age (RR 10.1; p=0.028), unstable hemodynamics (RR 7.6; p=0.002), chronic kidney disease C3- 5 (RR 5.6; p=0.03), history of stroke (RR 5.3; p=0.016) and chronic heart failure (RR 3.9; p=0.035).Conclusion. In modern clinical practice, the indications for thrombolysis often differ from those recommended, which leads to an increase in the number of bleeding and leveling of the positive effect on the prognosis. Factors such as advanced age, chronic heart failure and atrial fibrillation, stroke, chronic kidney disease, hemodynamic instability, hospitalizations with a different primary diagnosis, and the need for oxygen therapy increase the risk of early mortality
Predictors of post-infarction left ventricular aneurysm
Post-infarction left ventricular aneurysm (LVA) is a complication of myocardial infarction (MI), which is of great clinical importance due to high mortality. Data on its incidence are contradictory. The aim of the review was to highlight the existing and novel predictors of post-infarction LVA, the identification of which will help in identifying high-risk patients in order to optimize their treatment and rehabilitation. Known predictors of post-infarction LVA include pain-to-balloon time, age, female sex, recurrent MI, coronary angiography parameters, echocardiography, and electrocardiography. Increased levels of leukocytes, C-reactive protein, growth differentiation factor, stimulating growth factor, interleukin-1Ξ², interleukin-6, tumor necrosis factor-Ξ±, matrix metalloproteinases, proprotein convertase subtilisin-kexin type 9, N-terminal pro-brain natriuretic peptide >400 pg/ml indicate the risk of pathological left ventricular remodeling and LVA. In this connection, there is a need to assess the incidence of post-infarction LVA and a comprehensive assessment of its predictors in patients with MI
Myocardial infarction in combination with anaphylactic shock (Kounis syndrome): a case report
Introduction. Allergic reactions and side effects are a common consequence of drug use and account for ~5% of all hospital admissions. The co-occurrence of ana phylactic shock and acute myocardial infarction (AMI) is called Kounis synd rome (KS).BriefΒ description. The article analyzes the case of ceftriaxone-induced KS in a 56-year-old female patient with a history of anaphylactic shock after ampicillin therapy. The patient was treated on an outpatient basis due to an acute upper respiratory infection. The patient was diagnosed with acute bronchitis, in connection with which antibiotic therapy with azithromycin was started. Due to inefficiency the drug was canceled and ceftriaxone 1 g in 3,5 ml of 1% lidocaine solution 2 times a day was prescribed. After the first intramuscular injection, the patient developed anaphylactic shock, which was stopped by intravenous administration of prednisolone 120 mg, dexamethasone 8 mg and adrenaline hydrochloride 1,0 ml. Almost immediately, the ST segment elevation was recorded, in connection with which thrombolytic therapy with fortelyzin 15 mg was performed. Coronary angiography revealed thrombotic occlusion of the left anterior descending artery in the upper segment. Further examination verified AMI in the patient.Discussion. This case of AMI is pathogenetically associated with anaphylactic shock. However, the available data on the state of patient coronary system and no data on the morphologic characteristics of thrombus do not make it possibelr to define a type of KS.Conclusion. This clinical case indicates the need for a thorough allergic anamnesis collection by physicians of any specialty and prescribing medications taking it into account
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

The function of external respiration was tested for a group of eliminators (103 persons) and a control group (52 persons). The indices monitored were as follows: a forced expiration volume during the first second, the forced vital capacity and the expiration peak volume rate. When comparing two groups for the same rate of the third index decrease the decrease of the two first indices was more frequent and the degree of the forced exspiration volume was significantly larger in the group of eliminators. An inhalation provokative test with 0.5 and 1 % metaholin solution was performed in order to reveal hyperreactivity. The test has shown out a tendency towards the hyperreactivity rate growth for the eliminators. Consequently the investigation has made it possible to determine high rate of disturbances in bronchial permeability and the bronchus hyperreactivity for those involved in the elimination of the consequences of the failure at the Chernobyl atomic power station.ΠΡΠΎΠ²Π΅Π΄Π΅Π½ΠΎ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠ΅ ΡΡΠ½ΠΊΡΠΈΠΈ Π²Π½Π΅ΡΠ½Π΅Π³ΠΎ Π΄ΡΡ
