ABSTRACT
INTRODUCTION: Patients with acute coronary syndrome without ST segment elevation are a heterogeneous group with respect to the risk of having a major adverse cardiac event (MACE). A history of diabetes mellitus (DM) is no doubt one of the factors that define a patient as being at a higher risk of having the syndrome. AIM: To compare early invasive strategy with selective invasive strategy indicated for patients with and without DM.
PATIENTS AND METHODS: The study enrolled 178 patients with unstable angina or non-ST elevation myocardial infarction (UA/NSTEMI), and of these 52 (29.2%) had DM. Patients were randomly assigned to an early invasive strategy (these were scheduled to undergo coronary arteriography and percutaneous coronary intervention within 24 hours after admission) or to a selective invasive strategy (at first these were medically stabilized, with coronary arteriography required only in case of angina recurrence and/or evidence of inducible myocardial ischemia). The patients were followed up for a mean period of 22.8 ± 14 months.
RESULTS: In the follow up the diabetics allocated to an early invasive strategy were found to have a significantly lower angina recurrence incidence (p = 0.005), rehospitalization rate (p = 0.001), fewer arteriographies (p = 0.001) and coronary interventions (p = 0.001) and low cumulative incidence of MACE (p = 0.008) in comparison with the diabetics assigned to selective invasive strategy. We also found, using the Kaplan-Meier curves survival analysis, that the time to MACE in patients assigned to an early invasive strategy was significantly longer than that in the group of selective invasive strategy. In the follow-up of non-diabetics we found no significant difference in MACE rate between the patients allocated to early invasive strategy and those assigned to selective invasive strategy. In the selective invasive strategy group, however, the cardiovascular adverse events tended to occur earlier than in the early invasive strategy group.
CONCLUSIONS: Early invasive strategy in diabetic patients with non-ST-segment elevation acute coronary syndrome is associated with a reduced MACE rate compared with the selective invasive strategy used in these patients. Early invasive strategy applied in diabetic patients is also associated with a significantly longer time to MACE. In non-diabetics the advantages of early over selective invasive strategy are not so clearly differentiated.

ABSTRACT
AIM: To examine the relationship between physical activity (PA) and various cardiometabolic risk factors during an oral glucose tolerance test (OGTT), including glycemic spikes (PGS) in individuals at risk for type 2 diabetes.
SUBJECTS AND METHODS: A total of 949 middle-aged subjects from the Risk factors in Impaired Glucose Tolerance for Atherosclerosis and Diabetes (RIAD) trial aged 40-70 years were included in the present cross-sectional analysis. Standard 75 g OGTT was performed and blood was collected every 30 min for 2 hours for measurements of plasma glucose (PG) and other cardiometabolic risk factors. PA was assessed using interviewer-administered questionnaire.
RESULTS: Post-challenge PGS and maximal PG (PGmax) during OGTT were significantly lower in individuals with high PA vs. individuals with low PA even after body mass index (BMI) adjustment (p = 0.026 and p = 0.035, respectively). In univariate analysis post-challenge PG 30, 60, 90, and 120 minutes, PGS and PGmax during OGTT were significantly inversely correlated to PA. This correlation was attenuated but remained significant after adjustment for BMI. Fasting PG and glycosylated hemoglobin were not correlated to PA. Significantly higher fasting and post-challenge insulin levels were found among subjects with low vs. subjects with medium (p < 0.05) and high PA (p < 0.05). Post-challenge C-peptide and proinsulin levels were significantly lower in participants with high vs. participants with low PA (p < 0.05 for all). The relationship between 2-h PG and PA was observed also in lean subjects and in subjects with normal fasting glucose. In multivariate analysis PA was a significant independent determinant of 2-h PG.
CONCLUSION: We found a strong inverse relationship between PA and various post-challenge cardiometabolic parameters during OGTT, including glycemic spikes, in a population at risk for diabetes. This relationship was only partially dependent on BMI.
A Novel Physical Therapy Method of Treating Myofascial Pain Due to Muscle Spasm and Shortening
Authors: Aleksiev Assen R. 
Published: September 2013

ABSTRACT
AIM: Evaluation of the effect of a novel physical therapy method - post-isometric relaxation taping (PIR-taping) - compared with the effect of a conventional postisometric relaxation (PIR) in the treatment of outpatients with myofascial pain as a result of muscle spasm and shortening of static muscles, resulting in muscle imbalance.
PATIENTS AND METHODS: The study recruited 320 outpatients with myofascial pain due to muscle spasm and shortening, resulting in muscle imbalance in one of 8 kinetic segments. We treated randomly 8 groups of 20 patients by PIR and 8 matched groups by PIR-taping. The treatment consisted of one procedure daily (PIR or PIR-taping) with duration of 10 minutes for 10 working days. The pain was assessed by a visual analogue scale before and after each procedure.
RESULTS: The pain decreased significantly after the treatment course in each group (p < 0.05), but no difference was found between any pair of groups (p > 0.05). The pain before the next PIR procedure tended to increase in comparison with the pain after a previous one, unlike the pain in PIR-taping treatment which tended to decrease. Pain intensity after PIR procedure decreased significantly compared with the pain after a previous one (p < 0.05), while in PIR-taping - after two previous procedures (p < 0.05). Treatment with PIR increased pain significantly during the weekends (p < 0.05), while in treatment with PIR-taping the pain decreased insignificantly during the weekends (p > 0.05). The pain reduced significantly after PIR procedure (p < 0.05), as well as after PIR-taping procedure (p < 0.05). The pain after PIR procedure was significantly lower than that after PIR-taping procedure (p < 0.05), although the pain before PIR procedure was statistically equal with the one before PIR-taping procedure (p > 0.05).
CONCLUSION: Despite the better short-term effect of PIR versus PIR-taping, there was no difference between the final results of both methods, due to the continuous (24-hour) effect of PIR-taping.
The effect of tunnelling on repeated precise levelling measurements for vertical deformation control of the Metro4 project
Authors: Égető Cs. , Földváry L. , Huszák T. 
Published: September 2013

Abstract The effect of the construction of the 4th subway line of Budapest (Metro4) on the potential surfaces of the gravity field has been simulated, using the prism modelling technique. In the study mass loss due to the excavation of the two tunnels and of the stations has been considered. Mass variations deform the level surfaces; as so, the vertical reference surface of the levelling measurements is changing by time. In this study, the effect of the mass loss on levelling measurements was determined at a level 1 m above the ground, roughly simulating common instrument heights. Subsequently, the effect of the actual deformations of the surface on the levelling measurements has also been determined. According to the results, under certain arrangements of the levelling line with respect to the position of the excavations, the error due to the change of the vertical reference is in the 1μm order of magnitude, thus negligible.
The effect of correlation on uncertainty estimates – with GPS examples
Authors: Jansson P. , Persson C.-G. 
Published: September 2013

Abstract This article deals with the effect of correlation on the estimates of measurement uncertainty, with some focus on Global Positioning Satellite (GPS) time series analysis. Analytical derivations and Monte Carlo simulations form the theoretical basis, which shows that uncompensated correlation produces unrealistic uncertainty estimates. Tools for handling correlation in connection with estimation of uncertainty, construction of confidence intervals, hypothesis testing, design of measurement strategies, and development of tolerances are outlined and demonstrated. The GPS observation time series used in the article has a short to medium range correlation, and can therefore be handled with the presented tools - based on a simple Location-model and stationary stochastic processes.

Published: September 2013

AbstractThe National Geodetic Survey (NGS) performed a few test flights using Micro-g’s Turnkey Airborne Gravity System (TAGS) at altitude of 1700, 6300 and 11000 meters over Alabama in 2008. The cross-track spacing was 10 km for the two lower flights and 5 km for the highest flight. The test flights not only provided important information regarding the precision and accuracy of the TAGS but also revealed the impact of flight altitudes and track spacing on the collected gravity data. The gravity anomalies at three altitudes were modeled using 3-dimensional Fourier series, then compared at the three altitudes. The agreement was excellent - the gravity anomalies agree with each other from 1.4 to 3.3 mGal RMS at the three altitudes. When the bias was removed, the agreement was improved to better than 1.1 mGal. On the ground (h =0), the three gravity models agree from 1.9 to 3.8 mGal RMS. After removing the mean, the agreement improved to better than 1.7 mGal. Similar results were obtained in comparison with recent surface gravity which was of sub-mGal accuracy. The overall agreement between the downward continued airborne gravity and the surface gravity was better than 1.7 mGal after removing the mean values.As expected, the flight altitude had a direct impact on accuracy of the values of gravity downward continued to the Earth’s surface. The comparisons with terrestrial gravity show that gravity collected at 11000 m is having an accuracy of ±3 mGal on the ground. This accuracy is slightly worse than the other two altitudes most probably due to smaller signal/noise ratios and larger downward continuation effects. The RMS values of differences between the downward continued airborne gravity at altitude 1700 and 6300 meters and the surface gravity are 2.0 and 1.6 mGals, respectively. Based on these comparisons, airborne gravity data collected at altitudes below 6300 meters should result in accuracy better than ±2 mGals on the ground. Note, however, that the test area is flat and the accuracy of airborne gravity would likely be worse in more rugged mountainous regions.
School Autonomy and Leadership in Lithuania: Can School Leaders Help Schools to Take a Step forward ?
Authors: Honingh Marlies , Urbanovič Jolanta 
Published: September 2013

Abstract
In the literature, the school leader (head of school) is considered a key figure in strengthening school autonomy and stimulating the further development of the school organization. To improve the functioning of school leaders a centralized assessment of all candidates who want to become school leaders was introduced in Lithuania in 2011. The findings of a qualitative study into the first experiences with the assessment provide a deeper understanding of current school leadership problems in Lithuania. A comparison of these findings with the literature on school leadership and the assumptions underlying the recently changed school-leader appointment procedure reveal the lack of a clear vision on school leadership. Some general management competences - such as managing and motivating people, making decisions and strategic thinking - are underdeveloped.
A numerically efficient approach to the modelling of double-Qdot channels
Authors: Shamloo A. , Sowa A.P. 
Published: September 2013

AbstractWe consider the electronic properties of a system consisting of two quantum dots in physical proximity, which we will refer to as the double-Qdot. Double-Qdots are attractive in light of their potential application to spin-based quantum computing and other electronic applications, e.g. as specialized sensors. Our main goal is to derive the essential properties of the double-Qdot from a model that is rigorous yet numerically tractable, and largely circumvents the complexities of an ab initio simulation. To this end we propose a novel Hamiltonian that captures the dynamics of a bi-partite quantum system, wherein the interaction is described via a Wiener-Hopf type operator. We subsequently describe the density of states function and derive the electronic properties of the underlying system. The analysis seems to capture a plethora of electronic profiles, and reveals the versatility of the proposed framework for double-Qdot channel modelling.
RankEval: Open Tool for Evaluation of Machine-Learned Ranking
Authors: Avramidis Eleftherios 
Published: September 2013

Abstract
Recent research and applications for evaluation and quality estimation of Machine Translation require statistical measures for comparing machine-predicted ranking against gold sets annotated by humans. Additional to the existing practice of measuring segment-level correlation with Kendall tau, we propose using ranking metrics from the research field of Information Retrieval such as Mean Reciprocal Rank, Normalized Discounted Cumulative Gain and Expected Reciprocal Rank. These reward systems that predict correctly the highest ranked items than the one of lower ones. We present an open source tool ”RANKEVAL” providing implementation of these metrics. It can be either run independently as a script supporting common formats or can be imported to any Python application.
XenC: An Open-Source Tool for Data Selection in Natural Language Processing
Authors: Rousseau Anthony 
Published: September 2013

Abstract
In this paper we describe XenC, an open-source tool for data selection aimed at Natural Language Processing (NLP) in general and Statistical Machine Translation (SMT) or Automatic Speech Recognition (ASR) in particular. Usually, when building a SMT or ASR system, the considered task is related to a specific domain of application, like news articles or scientific talks for instance. The goal of XenC is to allow selection of relevant data regarding the considered task, which will be used to build the statistical models for such a system. It is done by computing the difference between cross-entropy scores of sentences from a large out-of-domain corpus and sentences from a corpus considered as in-domain for the task. Written in C++, this tool can operate on monolingual or bilingual data and is language-independent. XenC, now part of the LIUM toolchain for SMT, is actively developed since December 2011 and used in many MT projects.
Calozodion Moyas, A New Metapseudid Species (Crustacea: Tanaidacea: Apseudomorpha) from the Moroccan Atlantic Coast
Authors: Menioui Mohamed 
Published: September 2013

Abstract
A new apseudomorph tanaidacean species, Calozodion moyas sp. nov., from the Moroccan Atlantic waters is described. The new species is the third species of the genus Calozodion Gardiner, 1973 known in the western African coasts and the tenth in the worldwide fauna. The main features by which the new species differs from all others of the genus Calozodion consist in the presence of a mediodorsale process at the basis of pereopod 2 (absent in C. bacescui Guţu, 1996, C. dollfusi Guţu, 1989, C. heardi Guţu, 2002, C. multispinosum Guţu, 1984 and C. singularis Guţu, 2002) and of five long setae on the first article of mandible palp (comparatively to at most three setae in the species C. dominiki Bochert, 2012, C. simile Guţu, 2006, C. suluk Bamber & Sheader, 2005 and C. wadei Gardiner, 1973). Other differences result from the identification key of the species of the genus Calozodion presented in the final part of this paper.

Surface modification of cotton fabrics for sublimation printing
Authors: Bemska Jadwiga , Szkudlarek Joanna 
Published: September 2013

Abstract
The use of sublimation thermal transfer printing onto cotton is not widely practiced because of the lack of disperse
dyes affinity for cellulose fibres. The studies were performed onto polymer application on cotton fibres in order to
achieve the ability to absorption of sublimating dyes and thus the possibility of making printouts onto cotton. The
following parameters were evaluated: whiteness degree after impregnation, the relative strength of colours of the
obtained printouts, test washing fastness, and dry and wet rubbing fastness.

Authors: Unlu Mehtap Deniz , Goller Gultekin , Yucel Onuralp , Sahin Filiz Cinar 
Published: September 2013

Abstract
Silicon carbide ceramics were fabricated using the spark plasma sintering technique without the use of additives. The sintering process was carried out at four different temperatures in the range of 2 073−2 223 K under two different pressures, 40 MPa and 80 MPa, under vacuum. The effects of different temperatures and pressures on the density, Vickers hardness, fracture toughness, and microstructure were examined. Fully dense monolithic silicon carbide ceramics with a relative density of approximately 99 % were obtained. Increasing the pressure from 40 to 80 MPa and the temperature from 2 073 to 2 223 K resulted in an increase in the relative densities of spark plasma sintered ceramics from 87 % to 97.5 % and 95.5 % to 99.7 %, respectively. The results revealed that the silicon carbide ceramic spark plasma sintered at 2 223 K while applying 80 MPa of pressure with a 5-minute soaking time under vacuum has the highest hardness and fracture toughness values of 31.9 GPa and 3.6 ± 0.3 MPa·m1/2, respectively.

Published: September 2013

Abstract
This paper examines the feasibility of thixoforming two commercial aluminum–copper alloys: AA2011 and AA2014. This evaluation was performed in three steps: 1) characterization of the raw materials, including an analysis of their constituents, partial melting range temperatures, and microstructures; 2) characterization of the samples' morphological evolution during partial melting to observe their globularization at two different sets of temperatures, (solid fractions of 45 % and 60 %), and four holding times: 0, 30, 90 and 210 s; and 3) tests of the morphological behavior under the same partial melting conditions of temperature and holding times. The results indicate that, despite the difficulty of controlling the temperature of the semi-solid transition, these two alloys are suitable for thixoforming processes. Their morphology is stable in the semi-solid range and the corresponding viscosity values are lower than 106 Pa · s, resulting in a maximum conformational stress of 2.4 MPa.
XPS measurements of LDX 2101 duplex steel surface after magnetoelectropolishing
Authors: Rokosz Krzysztof , Hryniewicz Tadeusz 
Published: September 2013

Abstract
The work presents the X-ray photoelectron spectroscopy measurement results of LDX 2101 duplex steel surface after magnetoelectropolishing in comparison with the results obtained after a standard electropolishing in still electrolyte and in the electrolyte with moderate mixing. A considerable improvement of the steel surface was found to appear after the magnetoelectropolishing treatment concerning the general composition. The calculated ratio of chromium compounds to iron compounds Cr-X/FeX equals 2 after magnetoelectropolishing and only 0.5 after a standard electropolishing. On the other hand, the ionic Cr6+ content after magnetoelectropolishing was the lowest (2.77 at.%), and after a standard electropolishing it was the highest (30.3 at.%). Such results are expected to influence the corrosion behavior of the steel and increase the corrosion resistance greatly.
A Large Keratocystic Odontogenic Tumor
Authors: Jolly Saurabh , Lata Jeevan 
Published: September 2013

ABSTRACT
Keratocystic odontogenic tumor (KCOT) is described as a benign uni- or multicystic, intraosseous tumor arising from the dental lamina or its remnants. Various treatment modalities available are decompression, marsupialization, enucleation, curettage, resection with and without continuity defect, and disarticulation. Among all of these treatment modalities for large keratocystic odontogenic tumor, marsupialization followed by enucleation is preferred owing to its conservative nature as it decreases the size of the cystic cavity gradually thus, it can save the adjacent anatomic structures. Here, we describe a case of large KCOT which was treated using conservative approach.

ABSTRACTThe aim of our study is to verify whether some maternal features are related to pregnancy outcome of emergency cerclage when membranes are protruding through the dilated cervix. We present a retrospective review of 20 cases of emergency cervical cerclage performed over a 3 years period at Al Wasl hospital, a tertiary level centers in Dubai. Analysis shows presence of membrane prolapse with infection causing rupture of membranes, to be the strongest predictor of poor outcome. Analysis also reveals a significant association between initial white blood cell count and perinatal outcome.

Published: September 2013

ABSTRACTRhabdomyoma is one of the commonest cardiac tumor detected in prenatal ultrasound. Though its benign and self-limiting, it has a strong association with tuberous sclerosis, and hence needs thorough evaluation not only of the fetus but of the parents for signs of tuberous sclerosis. When isolated, fetus with rhabdomyoma needs to be only followed up for any cardiac complications associated with the mass and delivered.How to cite this articleGanesh C, Sridhar A.
