Quest Trail: An Effective Approach for Construction of Personalized Search Engine

Personalized search refers to search experiences that are tailored specifically to an individual's interests by incorporating information about the individual beyond specific query provided. Especially people working in a software development organization (analysts, developers, testers, maintenance team members), find it increasingly difficult to get relevant results to their searches. We propose methods to personalize searches by resolving the ambiguity of query terms, and increase the relevance of search results in order to match the user‟s interests. Difficulty in web searches has given rise to the need for development of personalized search engines. Personalized search engines create user profiles to capture the users‟ personal preferences and as such identify the actual goal of the input query. Since users are usually reluctant to explicitly provide their preferences due to the extra manual effort involved, the search engine faces the entire burden of predicting the user‟s preferences and intentions behind a query in order to yield more relevant search results. In this paper we define a QUEST to be the objective of user‟s search; here we combine quest level analysis of user‟s search logs and semantic analysis of the user‟s query in order to personalize user‟s search results. Most personalization methods focus on the creation of one single profile for a user and apply the same profile to all of the user‟s queries. Hence we propose a personalized search for a software development organization by creating QUEST or domain based profile rather than individual user based profile.
Value Creation through Cross-Border Mergers and Acquisitions An Empirical Study on European Acquirers of US Targets

The present paper analyzes the valuation effects of geographical diversification by examining mergers and acquisitions involving acquirers from 12 developed European countries and U.S. target firms over the period 1999-2007. Our findings suggest that acquisitions of overvalued U.S. targets do not cause, on average, any significant change in the excess values of European acquirers. However, after controlling for the undervaluation of the targets, we find that acquiring a fairly valued or undervalued company has no statistically significant influence at 10% level, but it is value enhancing at 12% significance level. Besides undervaluation of the target firm, other factors that influence the change in excess value of the acquirer are the cultural difference between the merging firms’ countries (negative impact) and the strength of the bidder’s currency (positive impact). Furthermore, it was found that target firm shareholders experience significant wealth gains of over 25% from the announcement date up until delisting.
Correlation of Trichoscopic Findings in Androgenetic Alopecia and the Disease Severity

Background: Androgenetic alopecia (AGA) refers to the appearance of the common nonscarring progressive patterned loss of terminal hair on the frontal scalp and/or vertex of the scalp in both men and women, seen with increasing age in genetically predisposed individuals. Until recently, a scalp biopsy was the only objective tool to diagnose and monitor the disease severity. Trichoscopy of scalp is a new noninvasive technique applied to facilitate the diagnosis of hair and scalp disorders using a manual or video dermatoscope. We found a significant difference in some of the variables such as brown peripilar sign (BPPS), white peripilar sign (WPPS), focal atrichia which may aid in the diagnosis of early and late stages of both male and female AGA along with its clinical correlation. No significant difference in the occipital area was found in all AGA patients. Aims: This study aims to study the trichoscopic findings of AGA and to correlate their relationship with disease severity in our tertiary care hospital. Settings and Design: This was a prospective, observational study. Subjects and Methods: A total of 91 patients (66 males and 25 females) of the age group between 18 and 70 years, were included in the study at the outpatient department of dermatology in 1 year. Each patient underwent a detailed general physical, systemic, and dermatological examination. The diagnosis of AGA was based on clinical grounds. The type of hair loss in each patient was recorded. Trichoscopic evaluation and capture of trichoscopic images was performed using an eScope Oitez Digital Microscope. Ethics: In accordance with the Helsinki Declaration of 1975 (revised in 2000), the study was approved by Ethical and Scientific Research committees of Care Institute of Medical Sciences, Hyderabad. Statistical Analysis Used: Statistical analysis was carried out with R-studio. Statistical significance in the difference in the outcome variables between the stages was assessed by Fisher's exact test. The statistical test was considered statistically significant at P < 0.05. Results: A positive correlation between clinical and trichoscopic findings with respect to disease severity was seen in some of the variables in our study. Both male and female AGA patients have hair shaft thickness heterogeneity as the most common feature. BPPS is seen in early grades of AGA (P < 0.01); WPPS and focal atrichia are seen in later grades of AGA (P < 0.01). Scalp honeycomb pigmentation was most commonly seen in all stages and is not correlated to the disease severity of AGA. Conclusion: As trichoscopy can reveal early variations in hair follicle diameter long before hair loss becomes clinically visible and has the advantage of examining larger areas in a relatively short duration makes it a practical choice for clinic set up. It adds new easily recognizable images for visual teledermatology. Besides, the easy documentation allows the doctor and patient to view the video graphics images simultaneously and helps in evaluating a therapeutic response by comparing it with pre-treatment images.
Late Weichselian and Holocene glacier fluctuations, equilibrium-line altitudes and palaeoclimate in Lyngen, northern Norway: a high-resolution composite chronology based on lacustrine and morpho-stratigraphical evidence

Based on lacustrine and morpho-stratigraphical evidence from Lyngen in Troms, northern Norway, thirteen marginal moraines have been mapped and dated in front of Lenangsbreene in Strupskardet. Moraines M1-M3 and M8-M9 are suggested orginally to be formed as ice-cored moraines, whereas M4-M7 and M10-M13 are suggested to be push and and melt-out moraines. A chronological framework, taking into account a combination of relict periglacial features, former shorelines and related glacier-meltwater channels, lichenometry, and AMS radiocarbon dated lacustrine sediments spanning the last 20,000 cal. yr BP, has been established. The proglacial lake Aspvatnet was isolated from the sea c. 10,300 cal. yr BP, and the lacustrine sediments have been investigated by use of LOI at 550/950oC, magnetic susceptibility, water content, wetand dry bulk density (DBD), and the magnetic parameters anhysteretic remanent magnetisation (ARM) and saturation remanent magnetisation (SIRM). There is in general good agreement between physical sediment parameters and magnetic parameters. DBD, a combination of medium and fine silt and the two statistical parameters ‘sorting’ and ‘mean’ have been used to construct a high-resolution glacier-fluctuation curve for the last 3800 cal. yr BP. Based on an accumulation-area ratio (AAR) of 0.6 and an adapted ‘Little Ice Age ratio’ (LR) approach, a continuous temperature-precipitation-wind equilibriumline altitude (TPW-ELA) curve for the last 20,000 cal. yr BP have been constructed. Using an established exponential relationship between mean ablation-season temperature and mean annual solid precipitation at the ELA of Norwegian glaciers, variations in mean winter precipitation as snow are quantified using an independent proxy for summer temperature. Mean annual winter precipitation varied from 500 to 5000 mm water equivalents, and on average, Holocene estimates is c. 50% higher than similar figures from the Lateglacial. The two driest periods occurred during Heinrich events 1 (H1) (17,500-16,500) and 0 (H0) (13,000-12,200), whereas freshwater pulses to the North Atlantic had apparently no systematic impact on mean winter precipitation. Based on the winter precipitation curve from Lyngen, the atmospheric circulation responded to the SST lowering associated with H1 and H0 events in Lyngen with formation of talusderived rock glaciers at sea level.
Distributed Agile Software Development Challenges and Mitigation Techniques: A Case Study

There is a growing interest in applying Agile development methods alongside global software development in order to reap the benefits of both approaches. With this said however, research has shown that software companies are encountering significant challenges when attempting this due to the contradiction between Agile values and the global development environment. This paper focuses on the challenges encountered with this kind of development and discusses several techniques via which these challenges can be addressed. It presents a case study and applies interviews with a software development company adopting the distributed Agile approach. From this study it can be seen that the communication barriers are the biggest development challenge. The development teams and product owners need to work hard to increase the level of communication between them by having a daily, regimented communication schedule. Flexibility with the working hours and location is an important practice with regards to limiting the barriers of the distributed development. Keywords-distributed Agile; global Agile; global software engineering; Agile software development.
Quantum Annealing for Ising Anyonic Syatems

We consider the quantum annealing for Ising anyonic systems. After giving a description of quantum annealing for Ising anyonic systems, we discuss its use for solving the practical problems, such as phylogenetics, linguistics and decision making. Our scope is not to show the details of calculation, but to invoke the interests on quantum annealing of anyonic systems to solve practical problems in various fields. In near future, this method might be widely spread as a technological foundation of machinery devices to solve the problems on many sights. *mmsato11@yahoo.co.jp
RESOLVING THE OPTICAL EMISSION LINES OF Lyα BLOB “B1” AT z = 2.38: ANOTHER HIDDEN QUASAR

We have used the SINFONI near-infrared integral field unit on the Very Large Telescope to resolve the optical emission line structure of one of the brightest (LLyα ≈ 1044 erg s−1) and nearest (z ≈ 2.38) of all Lyα blobs (LABs). The target, known in the literature as object “B1”, lies at a redshift where the main optical emission lines are accessible in the observed near-infrared. We detect luminous [O iii] λλ4959, 5007 and Hα emission with a spatial extent of at least 32 × 40 kpc (4″ × 5″). The dominant optical emission line component shows relatively broad lines (600–800 km s−1, FWHM) and line ratios consistent with active galactic nucleus (AGN) photoionization. The new evidence for AGN photoionization, combined with previously detected C iv and luminous, warm infrared emission, suggest that B1 is the site of a hidden quasar. This is confirmed by the fact that [O ii] is relatively weak compared with [O iii] (extinction-corrected [O iii]/[O ii] of about 3.8), which is indicative of a high, Seyfert-like ionization parameter. From the extinction-corrected [O iii] luminosity we infer a bolometric AGN luminosity of ∼3 × 1046 erg s−1, and further conclude that the obscured AGN may be Compton-thick given existing X-ray limits. The large line widths observed are consistent with clouds moving within the narrow-line region of a luminous QSO. The AGN scenario is capable of producing sufficient ionizing photons to power the Lyα, even in the presence of dust. By performing a census of similar objects in the literature, we find that virtually all luminous LABs harbor obscured quasars. Based on simple duty-cycle arguments, we conclude that AGNs are the main drivers of the Lyα in LABs rather than the gravitational heating and subsequent cooling suggested by cold stream models. We also conclude that the empirical relation between LABs and overdense environments at high redshift must be due to a more fundamental correlation between AGNs (or massive galaxies) and environment.
Postural Stability and Functional Capacity in Recreational Athletes with Type 1 Diabetes Mellitus

Aims: The aim of this study was to evaluate postural stability and functional capacity in recreational athletes with type 1 diabetes mellitus (T1 DM) and to compare them with healthy recreational athletes. Materials and Methods: Sixteen recreational athletes with T1 DM (21.4 ± 2.1 years of age, 174.3 ± 7 cm height, 64.5 ± 10.1 kg weight, 10.9 ± 5.3 body fat percentage [BFP]) and 19 healthy recreational athletes (21.9 ± 2.5 years of age, 173.1 ± 5.2 cm height, 66.1 ± 4 kg weight, 14.4 ± 1.5 BFP) participated in this study. Postural stability was measured by using the one leg standing test (OLST) (static test) and single limb hopping course (SLHC) test (dynamic test). Functional capacity was evaluated by using the isokinetic muscle strength test, one-legged and triple-legged hop for distance tests, and six meter (6-m) and cross 6-m hop for time tests. Mann-Whitney U test was used to compare mean values of the diabetic group (DG) with those of the control group (CG). Results: There was no difference between groups with regards to anthropometric data except in BFP (P 0.05). OLST (P < 0.05) and SLHC tests (P < 0.01) were significantly lower in the DG. Conclusions: These results suggest that diabetic athletes have reduced postural stability.
Immunomodulatory Effect of Mesenchymal Stem Cells in Multiple Sclerosis and Experimental Autoimmune Encephalomyelitis: A Review Study

Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system that may lead to disability of the patient. Current MS treatment regimens are still insufficient and research is conducted for developing more effective therapies capable of targeting neurodegeneration, inflammation, and demyelination. Recent results of experimental and clinical studies in cell-based therapy suggest Mesenchymal Stem Cells (MSCs) as potential candidates in autoimmune disorders. Immunomodulatory and neuroprotective properties of mesenchymal stem cells might offer the valuable therapeutic potential to modulate inflammatory responses associated with MS and repairing damaged nervous tissue. This review summarizes the main experimental studies and clinical trials using MSCs in MS.
Uncertainty analysis of hydrological ensemble forecasts in a distributed model utilising short-range rainfall prediction

Abstract. Advances in mesoscale numerical weather predication make it possible to provide rainfall forecasts along with many other data fields at increasingly higher spatial resolutions. It is currently possible to incorporate high-resolution NWPs directly into flood forecasting systems in order to obtain an extended lead time. It is recognised, however, that direct application of rainfall outputs from the NWP model can contribute considerable uncertainty to the final river flow forecasts as the uncertainties inherent in the NWP are propagated into hydrological domains and can also be magnified by the scaling process. As the ensemble weather forecast has become operationally available, it is of particular interest to the hydrologist to investigate both the potential and implication of ensemble rainfall inputs to the hydrological modelling systems in terms of uncertainty propagation. In this paper, we employ a distributed hydrological model to analyse the performance of the ensemble flow forecasts based on the ensemble rainfall inputs from a short-range high-resolution mesoscale weather model. The results show that: (1) The hydrological model driven by QPF can produce forecasts comparable with those from a raingauge-driven one; (2) The ensemble hydrological forecast is able to disseminate abundant information with regard to the nature of the weather system and the confidence of the forecast itself; and (3) the uncertainties as well as systematic biases are sometimes significant and, as such, extra effort needs to be made to improve the quality of such a system.
A Review of Stratigraphic Simulation Techniques and Their Applications in Sequence Stratigraphy and Basin Analysis

Stratigraphic simulation is a modelling methodology that can be used for exploration purposes to understand the key factors (sea-level change, subsidence, sediment supply rate) that control the stratigraphic geometries and architecture of a basin. Its application offers many advantages to scientists and researchers, as it provides a useful platform for analyzing and unraveling the complexities of sequence stratigraphy and basin development. A stratigraphic simulator models the stratal patterns of basins in various tectonic settings, such as in passive margins, foreland basins, retroarc foreland basins, interarc basins, remnant ocean basins, growth-faulted deltaic basins, and basins with salt diapirs. It enhances biostratigraphic interpretation by providing age constraints on stratal boundaries identified through sequence stratigraphic interpretation. This can lead to a systematic prediction of other geological aspects such as the distribution of source rocks, seals, and reservoirs. Furthermore, it may also lead to the identification of new accumulations or reservoirs within existing oil and gas fields. One type of stratigraphic simulation that is often used is a "forward stratigraphic simulation". This forward modelling method is usually applied to predict sediment distribution of a basin. In this paper, four simulation techniques (CSM, SEDPAK, DIONISOS, and SEDSIM) and their applications are presented. The models are typically applied to verify and infer the potential for hydrocarbon entrapment and accumulation in the basin. For this reason, stratigraphic simulation is useful for petroleum exploration and development. The simulation models are also useful as teaching tools for young geologists.
Compact Models for SqueezeFilm Damping in the Slip Flow Regime

We propose a mixedlevel simulation scheme for squeeze film damping effects in microdevices, which makes it possible to include damping effects in system level models of entire microsystems in a natural, physicallybased and flexible way. Our approach allows also for complex geometries, large deflection and coupling to other energy domains. In this work, we focus on the extension of our model to the slip flow regime. To this end, the flow problem is separated into appropriate blocks. For each block the slip factor is derived analytically or extracted from FEM simulations based on the Navier Stokes equation with slip boundary conditions. Our fully parametrized and, therefore, predictive mixedlevel model could be verified by FEM and experimental analysis.
ELECTRO TRA SPORT A D EMISSIO I DIAMO D

The diamond amplified photocathode has the potential to dramatically increase the average current available from photoinjectors, perhaps to the ampere-class performance necessary for flux-competitive fourthgeneration light sources. Electron emission from a diamond amplifier has been observed from hydrogenterminated diamond, using either photons or electrons to generate carriers. An emission gain of 40 has been achieved using a thermionic cathode and a gain of 6 from amplification of electrons from a photocathode. Very high average current densities (>10 A/cm) have been transported through the diamond using x-ray generated carriers. The electron affinity of hydrogen-terminated diamond has been measured to be about -1.1 eV.
Identification of Diagnostic-related Features Applicable to EEG Signal Analysis

The regulation of functions such as respiratory or heart rate in human body as well as the control of motor movements are under the control of nervous system. As these actions and correlated tasks are directly influenced by the brain, the brain monitoring gives the possibility to differentiate the tasks, enabling at the same time the prediction of further actions. In this contribution, publicly available electroencephalography (EEG) datasets are analyzed with respect to the detection of epileptic seizure occurrence and BCI-related actions (here: cued motor imagery). For these purposes, timefrequency- based feature extraction alongside different classification methods is used. To perform the classification, Artificial Neural Network (ANN) and Support Vector Machine (SVM) are utilized and compared with previously obtained results. The feasibility of particular features for the detection of epileptic seizures and BCI-related tasks is discussed. Four different feature vectors per analyzed problem are identified. Acceptable accuracy of classification using ANN- and SVMbased classifiers is achieved using identified feature vectors.
Partitioning of ethanol into lipid membranes and its effect on fluidity and permeability as seen by X-ray and neutron scattering

We present a combined neutron and X-ray scattering investigation to study the effect of ethanol on the molecular structure and dynamics of lipid membranes. 1,2-Dimyristoyl-sn-glycero-3-phoshatidylcholine (DMPC) powder hydrated with a 5 wt% ethanol solution (corresponding to 2 mol% of ethanol) was used in this study. From high-resolution X-ray experiments the position and partitioning of the ethanol molecules in the phospholipid bilayers was determined in their gel and fluid phases. We find that the ethanol molecules reside in the head group region of the bilayers, with 1.6 ethanol molecules per lipid molecule in the gel phase and 1.2 ethanol molecules per lipid molecule in the fluid phase. We find evidence for enhanced permeability in both fluid and gel phases of the phospholipid bilayers in the presence of ethanol molecules. Elastic and quasi-elastic neutron scattering data, obtained using a neutron backscattering spectrometer, was used to study slow, nanosecond molecular dynamics on length scales corresponding to lipid diffusion, acyl chain dynamics and solvent dynamics. While the presence of ethanol molecules had no observable effect on these types of dynamics in the fluid (Lα) phase, the membranes appeared to have a higher degree of order in gel (Lβ) and ripple (Pβ′) phases. In particular, lipid diffusion was found to be slower by a factor of two in the more rigid gel phase when ethanol was present.
Impact of Stability Ball Sitting during Semi-recumbent Exercise

Purpose: This study determined if sitting on a stability ball (B), when compared to sitting on a chair (C), affects cardiorespiratory and muscular recruitment during semi-recumbent exercise. Methods: Participants sat on B or C behind a cycle ergometer using the bike seat for hand griping. Open-circuit spirometry and HR were monitored continuously during graded exercise. Initial two stages of exercise also had hip movements and the right arm, trunk, and leg EMGs recorded. Eighteen apparently healthy adults exercised twice, one trial on B and the other trial on C (order randomized). ANOVA for repeated measures (α < 0.05) was used for statistical analysis. Results: Only at peak was VO2 significantly higher (P = 0.001) for B compared to C. There was no significant (P = 0.291) difference between B and C for HR. Stage 2 hip movements were significantly (P < 0.001) higher while some leg EMGs were significantly (P < 0.019) lower on B compared to C. In addition, flexor digitorum EMG was significantly (P < 0.036) higher on B compared to C. Conclusion: The stability ball increases hip motion and may alter muscular recruitment pattern during semi-recumbent exercise with little impact on cardiorespiratory parameters.
