Single Production of Fourth Family Sneutrino via RPV Couplings at Linear Colliders

The single production of fourth family sneutrino $\tilde{\nu}_{4}$ via R-parity violating interactions in electron-positron collisions has been investigated. We study the decays of $\tilde{\nu}_{4}$ into different flavor dilepton $e^{\pm}\mu^{\mp}$ via R-parity violation. It is shown that R-parity violating couplings $(\lambda_{411},\lambda_{412})$ down to 0.001 will be reachable at future linear colliders which would provide better accuracy comparing to the indirect measurements as complementary to the LHC results.Comment: 11 pages, 6 figure

Do the effects of vitamin d supplementation on muscle strength differ according to age?

Introduction: Vitamin D plays an important role in musculoskeletal health and its use improves muscle strength. However, the effect of vitamin D use on muscle strength in women of different ages is yet to be investigated. Therefore, in this study, we aimed to evaluate the effect of vitamin D use on muscle strength in women of different age groups and determine the differences of muscle strength gain between age groups. Materials and Method: Sixty-three women with calcidiol levels<30 ng/mL were randomly assigned and stratified by their age group as follows: Group I (aged 40–49 years), Group II (aged 50–59 years) and Group III (aged 60–69 years). Calcidiol levels, body mass index, fat free mass, percent fat, grip strength, arm curl, chair stand and isokinetic concentric flexor and extensor peak torque and power at 60°•s−1 and 180°•s−1 were assessed at baseline and six months after oral cholecalciferol supplementation. Results: Vitamin D supplementation caused significant improvement in body mass index, arm curl, grip strength and knee flexor and extensor peak torque and power at 60°•s−1 and 180°•s−1 in all groups (p<0.05). Knee flexor power at 60°•s−1 and extensor power at 180°•s−1 were significantly higher in group I than in group III (p<0.025). Conclusion: Muscle strength in response to vitamin D supplementation increased in all age groups, and isokinetic muscle power was the highest in the youngest age group studied. © 2018, Geriatrics Society.

Voting features based classifier with feature construction and its application to predicting financial distress

Voting features based classifiers, shortly VFC, have been shown to perform well on most real-world data sets. They are robust to irrelevant features and missing feature values. In this paper, we introduce an extension to VFC, called voting features based classifier with feature construction, VFCC for short, and show its application to the problem of predicting if a bank will encounter financial distress, by analyzing current financial statements. The previously developed VFC learn a set of rules that contain a single condition based on a single feature in their antecedent. The VFCC algorithm proposed in this work, on the other hand, constructs rules whose antecedents may contain conjuncts based on several features. Experimental results on recent financial ratios of banks in Turkey show that the VFCC algorithm achieves better accuracy than other well-known rule learning classification algorithms. © 2009 Elsevier Ltd.

The 1994-2004 Al Hoceima (Morocco) earthquake sequence: conjugate fault ruptures deduced from InSAR

Fas&rsquo;ın El H&uuml;seyma şehri 10 yıl arayla 26 Mayıs 1994 ve 24 Şubat 2004 tarihlerinde meydana gelen iki deprem (Mw=6.0; Mw=6.5) ile sarsılmıştır. G&ouml;m&uuml;l&uuml; doğrultu atımlı faylarda meydana gelen bu depremlerde y&uuml;zey kırığı oluşmamıştır. Aktif doğrultu atımlı faylar boyunca g&ouml;zlenen morfotektonik yapıların topoğrafyada &ccedil;ok belirgin olmaması ve sismik g&ouml;zlemlerin yetersizliği nedeniyle bu iki depremin hangi faylar &uuml;zerinde oluştuğu, kinematikleri ve birbirleri arasındaki ilişki ortaya &ccedil;ıkartılamamıştır. Bu &ccedil;alışmada Avrupa Uzay Ajansı&rsquo;nın (ESA) Envisat ve ERS uydularına ait radar g&ouml;r&uuml;nt&uuml;leri Sentetik A&ccedil;ıklık Radar İnterferometrisi (InSAR) y&ouml;ntemi ile işlenip bu iki depremin yery&uuml;z&uuml;nde meydana getirdiği y&uuml;zey deformasyonu farklı bakış a&ccedil;ılarından haritalanmış ve atım dağılımları modellenmiştir. Elde edilen kosismik interferogramlar ve nihai fay modelleri depremlerin k&ouml;r eşlenik faylar &uuml;zerinde meydana gelmiş olduğunu; 1994 depreminin sol yanal olup K23&deg;D doğrultusunda, 2004 depreminin ise sağ yanal ve K45&deg;B doğrultusunda olduğunu g&ouml;stermektedir. Bu sonu&ccedil; &ouml;nceki araştırmalarda sismolojik analizlerden elde edilen &ccedil;ıkarımlar ile &ccedil;elişmektedir. Son zamanlarda oluşan doğrultu atımlı faylarla ilişkili deprem aktivitesi g&ouml;stermektedir ki Kuzey Afrika-Avrasya levha sınırındaki Rif b&ouml;lgesi doğusunda ve batısında bindirme faylarıyla ilişkili depremlerin etkisi altındaki kuzey Cezayir ve Kadiz b&ouml;lgelerinden sismotektonik a&ccedil;ıdan farklılık g&ouml;stermektedir. El H&uuml;seyma ve civarında topoğrafyadaki hakim morfotektonik yapıların halen sıkışma rejimi &uuml;r&uuml;nleri olmaları bu b&ouml;lgedeki D-B y&ouml;nelimli a&ccedil;ılma ile uyumlu doğrultu atımlı tektonik rejimin yakın zamanda başladığı fikrini desteklemektedir.&nbsp;Anahtar Kelimeler: Eşlenik faylanma, InSAR, Rif, Fas, El H&uuml;seyma, aktif tektonik.We study the two North African earthquakes, May 26, 1994 (Mw=6.0) and February 24, 2004 (Mw=6.4) earthquakes that affected the Al Hoceima region of northern Morocco with the available InSAR data collected from both the ascending and descending orbits. Being the strongest earthquakes ever to be recorded instrumentally in the region, the analysis of the earthquakes has an important role in the tectonics of the region. The Rif Cordillera belong to the E-W trending thrust-and-fold system of north Africa that results from the collision between Africa and Eurasia. The system includes the Tell Atlas mountain ranges of Algeria and Tunisia along the Mediterranean coast to the east, and forms a collision tectonics strip along the African-Eurasian plate boundary. The ongoing shortening rate between the two plates decreases towards the west from 6.3 to 2.3 mm/yr from Sicily to northern Morocco. The seismicity along the boundary is rather complex and varies significantly from west to east. The Al Hoceima sequence indicate that the Rif is being deformed under a strike-slip tectonic regime. However adjacent regions in northern Algeria to the east and the Gulf of Cadiz to the west are subject to thrust faulting. Neotectonic features of the Rif consist of the major Nekor and Jebha, NE-SW trending left-lateral strike slip faults accompanied by N-S trending normal faults that form a graben-like structure east of Al Hoceima and a conjugate network of relatively small NW-SE and NE-SW strike-slip faults. The transpressive tectonics and existence of a complex fault network with different types of faulting in the Rif probably reflect the rapidly changing local tectonic regime with block rotations during the Neogene and Quaternary. Several strong earthquakes are known to have occurred in the historical times. The exact location, kinematics and relationships between the 1994 and 2004 earthquakes are poorly known since neither of them produced surface ruptures. Using Synthetic Aperture Radar interferometry (InSAR) we mapped the surface displacementfield of the two earthquakes to characterize their seismic source parameters. The availability of ascending and descending interferograms for both earthquakes allows us to constrain their rupture parameters with high confidence. We used European Space Agency's (ESA) ERS and Envisat SAR data, respectively. While the ERS Level-0 (raw) SAR data were processed using the JPL ROI_PAC software, the Envisat Level-1 (single-look) ASAR data were processed using DORIS SAR processing software, and precise satellite orbits from Delft University. The effect of topography which depends on the perpendicular separation between orbital trajectories is removed from the interferograms using the SRTM 3-arc-second (~90 m) posting digital elevation model. The interferograms were also filtered using a weighted power spectrum technique. We modelled the manually unwrapped fringes derived from the processed interferograms by using slip inversions on triangular fault patches instead of commonly used rectangular ones which enabled us to use non-planar more realistic fault models for the earthquakes. Analysis of the interferograms and subsequent elastic modeling  suggest that the two mainshocks occurred on blind conjugate strike-slip faults; the 1994 quake on a N23°E trending left-lateral and 2004 quake on a N45°W trending right-lateral fault. It is worthwhile to mention that, especially for the 2004 event, InSAR result contradicts previous inferences on the kinematics, location and rupture geometry of the earthquakes deduced from conventional analyses of seismic waveforms and aftershocks distribution which suggest a left-lateral fault plane instead of a right-lateral one. The InSAR analysis reveals the fragmentation of the Rif Mountain throughout a complex network of conjugate blind faults consistent with the transpression tectonics along the plate boundary in North Africa. Although the two earthquakes took place in the Rif thrust-and-fold belt, the late Quaternary deformation indicates E-W extension in agreement with the NW-SE and NE-SW trending conjugate strike-slip faulting. Keywords: Conjugate faulting, InSAR, Rif, Morocco, Al Hoceima, active tectonics

Glueball Production in Peripheral Heavy-Ion Collisions

The method of equivalent quanta is applied both to photon-photon and, by analogy, to double pomeron exchange in heavy-ion collisions. This Weizs\"acker-Williams approach is used to calculate production cross sections for the glueball candidate $f_J(1710)$ meson via photon-photon and pomeron-pomeron fusion in peripheral heavy-ion collisions at both RHIC and LHC energies. The impact-parameter dependence for total and elastic cross sections are presented, and are compared to results for proton-proton collisions.Comment: 15 pages, 6 figure

Selection of the best location for solar plants in Turkey

The unique properties of solar energy have led to increasing demands in various countries. In order to use solar energy effectively, environmental and geographical circumstances related to solar intensity must be considered. Different factors may affect the selection of suitable locations for solar plants. These factors must be considered concurrently for optimum location identification. This article presents an approach for the location of solar plants by data envelopment analysis (DEA). Efficiency scores over a twelve month period were evaluated by using a modified similarity to ideal solution (TOPSIS) method. This approach was applied to 30 different cities in different regions of Turkey

Non-equilibrium entangled steady state of two independent two-level systems

We determine and study the steady state of two independent two-level systems weakly coupled to a stationary non-equilibrium environment. Whereas this bipartite state is necessarily uncorrelated if the splitting energies of the two-level systems are different from each other, it can be entangled if they are equal. For identical two-level systems interacting with two bosonic heat baths at different temperatures, we discuss the influence of the baths temperatures and coupling parameters on their entanglement. Geometric properties, such as the baths dimensionalities and the distance between the two-level systems, are relevant. A regime is found where the steady state is a statistical mixture of the product ground state and of the entangled singlet state with respective weights 2/3 and 1/3
