Works Title Giant Slow Wave Resonance for Light Amplification and Lasing Permalink

We apply the idea of giant slow wave resonance associated with a degenerate photonic band edge to gain enhancement of active media. This approach allows to dramatically reduce the size of slow wave resonator while improving its performance as gain enhancer for light amplification and lasing. It also allows to reduce the lasing threshold of the slow wave optical resonator by at least an order of magnitude. Giant Slow Wave Resonance for Light Amplification and Lasing 2
What shapes patient's satisfaction in countries' health care systems?

Patient satisfaction is an important measure of health care quality as it offers information on the provider’s success at meeting clients’ expectations and is a key determinant of patients’ perspective behavioral intention. This paper studies the relationship between patient’s satisfaction of healthcare system and a set of socio-economic and health provision indicators. We first construct an index of patient’s satisfaction and then, at a second stage, this index is related to economic and health provision variables. Our empirical analysis relies on 31 countries and for four years. Our findings support a strong positive association between citizens’ satisfaction and public health expenditures, number of physicians and nurses, and the age of the patient, while there is a negative evidence for private health spending and number of hospital beds.
Cooxidation of Chalcones and Oxalic acid using Chromium (VI)

Chalcones can be easily oxidized in presence of oxalic acid, by Cr(VI) in acetic acid medium, the rate of cooxidation was found to be a fractional order with respect to the chalcones and its substituents. The order with respect to the chromic acid is unity whereas order with respect to oxalic acid is also a fractional order. The effect of various parameters such as [H + ], [NaCl], [NaNO 3 ] and dielectric constant of the medium by changing the (v/v) ratio of acetic acid and water content were studied . The intermediate is formed between chalcones and a chromic acid – oxalic acid complex, the presence of the molecule of oxalic acid within the complex facilitates the direct three electron – reduction of Cr (VI) to Cr (III), which is the rate – limiting step. From kinetic data obtained the activation parameters have been computed and suitable mechanism is proposed.
Forest recovery and river discharge at the regional scale of Guangdong Province, China

Information on how large‐scale forest changes affect water resources is important in China as country‐wide reforestation programs are being implemented and concerns have arisen over possible water reduction. In this study, water budget analysis and statistical methods were used to assess the effects of significant forest recovery on river discharge at Guangdong Province based on 50 years of data. We used realized water yield (RWY) as a balance term between the outflows from and inflows to the province to represent the river discharge produced solely in Guangdong Province. The relationship between forest recovery and RWY was inferred after quantitatively examining other contributing variables including precipitation, potential evapotranspiration, development of impervious areas, human water consumption, and reservoir constructions. We applied time series analysis to test the statistical relationship between forest recovery and RWYs at annual, wet season, and dry season intervals. Both approaches showed that large‐scale forest recovery did not cause significant water reduction over the past 50 years. This finding is contrary to the widely held perception of the trade‐off relationship between carbon (reforestation) and water. There were no significant trends in precipitation or in RWY annually and in the wet season, but there was a significant increase of RWY in the dry season over the past 50 years. It is estimated that forest recovery may play a positive role in redistributing water from the wet season to the dry season and, consequently, in increasing water yield in the dry season. The implication of those research findings for future reforestation programs and water resource protection is also discussed.
Expression of p 63 in anaplastic large cell lymphoma but not in classical Hodgkin ' s lymphoma ☆

Immunohistochemical determination of p63 protein is frequently used in the pathologic diagnosis of nonhematological solid tumors. In malignant hematological disease, p63 expression has been reported in 22% of follicular lymphoma, about 35% of diffuse large B-cell lymphoma, 23% of chronic lymphocytic leukemia, and in some cases of blast crisis of chronic myelogenous leukemia. Anaplastic large cell lymphoma is a rare disease that accounts for less than 5% of all cases of non-Hodgkin's lymphoma. There is little information concerning p63 expression in this specific type of lymphoma. In some cases, the morphological and phenotypic features between anaplastic large cell lymphoma and classical Hodgkin's lymphoma are similar, making this differential diagnosis challenging. We studied p63 expression using a tissue microarray approach in 154 cases of anaplastic large cell lymphoma, including 38% anaplastic large cell kinase positive and 62% anaplastic large cell kinase negative, and 58 Hodgkin's lymphoma cases. Sixty-eight cases of anaplastic large cell lymphoma (44%) showed p63 nuclear positivity (41% of anaplastic large cell kinase positive and 47% of anaplastic large cell kinase negative). Of 130 cases of systemic-anaplastic large cell lymphoma, 42% showed p63 positivity. The neoplastic cells expressed p63 in 38% of the cases of CD45-negative/ anaplastic large cell kinase–negative null cell–type anaplastic large cell lymphoma, a subgroup that offers the most difficulties in the differential diagnosis with classical Hodgkin's lymphoma. In contrast, none of the cases of classical Hodgkin's lymphoma demonstrated any p63 expression. These results demonstrate that p63 protein expression is frequently expressed in a subset of anaplastic large cell lymphoma cases and may be used as a potential tool in the differential diagnosis between anaplastic large cell lymphoma and classical Hodgkin's lymphoma.
Factors Affecting Egyptian Small and Medium Sized Owners’ Intentions to and Adoption of E-business

The revolution in communications and information technology has played an important role in changing people's day to day life, this in fact has reflected on the way people performing business. Nowadays, modern business is being shifted from paper-based, and peopleintensive systems toward electronic-based procedures using new communication tools. It is widely known that the adoption of new technology is not established from scratch, it is a product of cumulative factors and actions, that can be treated as a planned behaviour. In an analysis to investigate the intentions towards adoption of e-business as an entrepreneurial activity, this study relies on theoretical framework of Ajzen theory of planned behaviour. According to this theory human action is guided by three kinds of beliefs: beliefs about the future outcomes of the behaviour (behavioural beliefs), beliefs about the normative expectations of others and motivation to comply with these expectations (normative beliefs), and finally beliefs about the presence of factors that may facilitate or impede performance of the behaviour and the perceived power of these factors (control beliefs). Purposethe purpose of this paper is to explore and explain the factors that determine the intention for adopting e-business among small and medium sized firms in Egypt. Design/Methodology/ ApproachA review of the literature on e-business, technology adoption and entrepreneurial orientation and behaviour. Develop an integrated model linking endogenous factors and exogenous factors that determine intention of adopting e-business. Originality/ Value: The paper is among the first studies to examine factors enabling/ hindering the adoption of e-business among small and medium sized firms in Egypt.

Fecal short-chain Fatty acids at diFFerent time points aFter ceFtriaxone administration in rats

Short-chain fatty acids (SCFAs) are major products of the microbial fermentation of dietary fiber in the colon. Recent studies suggest that these products of microbial metabolism in the gut act as signaling molecules, influence host energy homeostasis and play major immunological roles. In the present study, we defined the long-term effects of ceftriaxone administration on the fecal SCFAs concentration in Wistar rats. Ceftriaxone (300 mg/kg, i.m.) was administered daily for 14 days. Rats were euthanized in 1, 15 and 56 days after ceftriaxone withdrawal. Caecal weight and fecal concentration of SCFAs were measured by gas chromatography. Ceftriaxone administration induced time-dependent rats’ caecal enlargement through accumulation of undigestable substances. One day after ceftriaxone withdrawal, the concentrations of acetic, propionic, butyric acids and total SCFAs were decreased 2.9-, 13.8-, 8.5-, 4.8-fold (P < 0.05), respectively. Concentration of valeric, isovaleric and caproic acids was below the detectable level. That was accompanied by 4.3-fold decreased anaerobic index and increased relative amount of acetic acid (P < 0.05). In 56 days, concentration of SCFAs was still below control value but higher than in 1 day (except for propionic acid). Anaerobic index was 1.3-fold lower (P < 0.05) vs. control. Conclusion: antibiotic therapy induced long-term disturbance in colonic microbiota metabolic activity.
Adaptive Wall-Modelled Large Eddy Simulation of Jet Noise in Isolated and Installed Configurations

The study of jet acoustics is crucial for future aeroengine designs. Although the highbypass ratio of modern turbofans can have a shielding effect on the core jet noise, there is an increased potential of interaction of the jet flow with wing and flap, and its effects on noise need to be thoroughly investigated. Wall-Modelled Large-Eddy Simulation (WMLES) is a powerful method to study the installation effects on jet noise, as it does not have strict near-wall requirements, allowing for a more uniform mesh for better noise propagation and a saving in computational cost. An adaptive wall model is here introduced and validated on channel flow, on the MD-30P/30N high-lift multi-element airfoil, and on the NASA High-Lift Common Research Model (HL-CRM). WMLES simulations, combined with the Ffowcs Williams and Hawkings (FW-H) sound extrapolation method, are performed on turbulent coaxial jets in isolated and installed configurations. Computed flow field and sound spectra present favourable agreement with experimental results, confirming key features of the installation effects on jet noise.
On the Relationship Between the North Atlantic Oscillation and Early Warm Season Temperatures in the Southwestern United States

AbstractIt is reported herein that the North Atlantic Oscillation (NAO), which has been known to directly affect winter weather conditions in western Europe and the eastern United States, is also linked to surface air temperature over the broad southwestern U.S. (SWUS) region, encompassing California, Nevada, Arizona, New Mexico, Utah, and Colorado, in the early warm season. The authors have performed monthly time-scale correlations and composite analyses using three different multidecadal temperature datasets. Results from these analyses reveal that NAO-related upstream circulation positively affects not only the means, but also the extremes, of the daily maximum and minimum temperatures in the SWUS. This NAO effect is primarily linked with the positioning of upper-tropospheric anticyclones over the western United States that are associated with development of the positive NAO phase through changes in lower-tropospheric wind directions as well as suppression of precipitation and enhanced shortwave radiat.
Student risk identification learning model using machine learning approach

Several challenges are associated with online based learning systems, the most important of which is the lack of student motivation in various course materials and for various course activities. Further, it is important to identify student who are at risk of failing to complete the course on time. The existing models applied machine learning approach for solving it. However, these models are not efficient as they are trained using legacy data and also failed to address imbalanced data issues for both training and testing the classification approach. Further, they are not efficient for classifying new courses. For overcoming these research challenges, this work presented a novel design by training the learning model for identifying risk using current courses. Further, we present an XGBoost classification algorithm that can classify risk for new courses. Experiments are conducted to evaluate performance of proposed model. The outcome shows the proposed model attain significant performance over stat-of-art model in terms of ROC, F-measure, Precision and Recall.
Identity of Pelodiscus sinensis revealed by DNA sequences of an approximately 180‐year‐old type specimen and a taxonomic reappraisal of Pelodiscus species (Testudines: Trionychidae)

Recent studies identified several distinct genetic lineages within the softshell turtle genus Pelodiscus that could represent valid species. Traditionally, Pelodiscus was regarded to comprise only a single species (P. sinensis). These softshell turtles are economically the most important chelonians of the world, with hundreds of millions of specimens traded as food every year. Moreover, Pelodiscus is used as a model organism for embryological and physiological studies, making correct species identification of paramount interest for disciplines beyond taxonomy. However, the understanding of the diversity of Pelodiscus was seriously hampered by the unclear taxonomic allocation of the oldest available species name, Trionyx (Aspidonectes) sinensis Wiegmann, 1834. To clarify its identity, we reconstructed two mitochondrial DNA fragments of 1013 bp (cytb)
”Katowice effect”? Regeneration of the site of the former Katowice coal mine through prestige cultural projects

Abstract This paper aims to give an in–depth account of the regeneration of the site of the former Katowice coalmine, by far the largest regeneration venture financed by the public sector on a post-industrial site in Poland, and to capture the primary outcomes and effects of this prestige project. Contrary to a simplified interpretation of a ‘Polish Bilbao effect’, the authors argue that the Culture Zone follows a unique development model that was driven by a coincidence of such factors as the situation of a major (post-) industrial conurbation seeking a new identity, the availability of external funding, chance events (with the origins of some of them dating back to WW2), and pre-existing spatial factors. The study area has been diagnosed to include all the positive effects of flagship projects, as well as most of the weaknesses associated with such a type of regeneration. All in all, it is a successful undertaking given the external conditions under which it has been implemented.
For the Pure-Play Firm: Find the True Cost of Capital for Your Capital Projects

Approving capital projects can be one of management’s toughest calls. One reason is while a project's return can be presented quantitatively, eg. , IRR, its risks have no comparable metric. The author addresses the problem by showing how to use a Monte Carlo simulation to measure your project’s risk and how to use that risk to find its true, risk-adjusted, cost of capital. In this system, risk is determined by variation in free cash flow. Since every project in your company’s pipeline will have a forecasted free cash flow, every project, including those with financial leverage, can be evaluated using the same economic yardstick. Other benefits include better value projects, better presentation and accurate discount rates for NPV.
A Scalar Field Dark Matter Model and Its Role in the Large-Scale Structure Formation in the Universe

We present a model of dark matter based on scalar-tensor theory of gravity. With this scalar field dark matter model we study the non-linear evolution of the large-scale structures in the universe. The equations that govern the evolution of the scale factor of the universe are derived together with the appropriate Newtonian equations to follow the nonlinear evolution of the structures. Results are given in terms of the power spectrum that gives quantitative information on the large-scale structure formation. The initial conditions we have used are consistent with the so-called concordance ΛCDM model.
BRAUER-KURODA RELATIONS FOR HIGHER CLASS NUMBERS

Arising from permutation representations of finite groups, Brauer-Kuroda relations are relations between Dedekind zeta functions of certain intermediate fields of a Galois extension of number fields. Let E be a totally real number field and let n ≥ 2 be an even integer. Taking s = 1 − n in the Brauer-Kuroda relations then gives a correspondence between orders of certain motivic and Galois cohomology groups. Following the works of Voevodsky and Wiles (cf. [33], [36]), we show that these relations give a direct relation on the motivic cohomology groups, allowing one to easily compute the higher class numbers, the orders of these motivic cohomology groups, of fields of high degree over Q from the corresponding values of its subfields. This simplifies the process by restricting the computations to those of fields of much smaller degree, which we are able to compute through Sage ([30]). We illustrate this with several extensive examples.
Evaluation of two knowledge-based fault locators for power distribution systems

This paper presents the implementation of two knowledge-based methods to locate faults on power distribution systems with distributed generation, to improve the power quality as demanded by the regulated electrical markets. Fault location methods could use additional measurements as new information to improve the results. ID3 decision tree and k nearest neighbor methods are implemented using measurements at substation and at the distributed generation nodes. The methods are validated using a modification of the IEEE 34-node test feeder, with two distributed generators. Several operating scenarios are considered by varying the model parameters of the power system. Additionally, a sensitivity analysis is performed to find the most critical parameters that affect the fault location methods. The results show the good performance of the fault locators and help to determine the most critical parameters of the power distribution system.
Interactions Between Dutch Midwater Trawl and Atlantic White-sided Dolphins (Lagenorhynchus acutus) Southwest of Ireland

Incidental catches of cetaceans in the Dutch pelagic trawl fishery are largely restricted to late-winter early-spring in an area along the continental slope southwest of Ireland. Available evidence indicates that annual variations in such incidents are large. Using combined mid-water trawl by-catch and dolphin stomach content data, the hypothesis is put forward that Atlantic white-sided dolphin (Lagenorhynchus acutus), normally a more oceanic species, may actively search for mackerel (Scomber scombrus) closer to shore in early-spring, at least in some years. Supporting data were from an observer program during 1992–94, which covered seven trips representing 5% of the annual effort in the fishery. Also over the period 1989–94, a total of 71 records of by-catch incidents were collected (involving a minimum of 312 individuals), of which 41 occured in 1994 (172 individuals). Approximately 90% of the incidents occurred late-winter early-spring, when both the mackerel and horse mackerel (Trachurus trachurus) pelagic fisheries were operating in the same area, southwest of Ireland. Incidence frequency peaked by late February and March, when mackerel is known to move into the area during its southward migration. The Atlantic white-sided dolphin was the main cetacean species in the by-catch (83% of all identified individuals). Other species recorded included long-finned pilot whale (Globicephala melas), short-beaked common dolphin (Delphinus delphis), bottlenose dolphin (Tursiops truncatus) and the white-beaked dolphin (Lagenorhynchus albirostris). The stomachs of 47 Atlantic white-sided dolphins, 11 common dolphins, two bottlenose dolphins and one white-beaked dolphin were examined. Fresh mackerel remains were found in nearly all white-sided dolphin stomachs, whereas fresh horse mackerel remains occured only in stomachs of bottlenose and common dolphins. Deep-water fish otolith incidents suggested that white-sided, common and bottlenose dolphin had completely different diets before moving to the southwest of Ireland.
Desain Model Manajemen Layanan TI berbasis Information Technology Infrastructure Library (ITIL)

Along with the increasing need for services in organizations, especially in the field of Information Technology (IT), the IT paradigm which initially only focused on data processing and manipulation, is now beginning to shift to strategic planning and IT services. IT Service Management (ITSM) is a method of managing information technology systems that seek to align IT with business needs to manage the provision of efficient IT services with quality assurance. ITIL (Information Technology Infrastructure Library) is one of the Frameworks in ITSM, ITIL is a popular / widely used Framework in ITSM research. Atma Jaya Yogyakarta University (UAJY) is one of the major private universities in Yogyakarta and is also increasingly complex in providing services to its academic community. The use of IT in UAJY is manifested in a variety of services that can support the needs of every user. This research resulted in an IT service design that will be used by students and lecturers. This research focuses on the Service Design phase which will produce a Service Design Package (SDP) using the ITIL Framework.
Exploring Graph-Algebraic CCG Combinators for Syntactic-Semantic AMR Parsing

We describe a new approach to semantic parsing based on Combinatory Categorial Grammar (CCG). The grammar’s semantic construction operators are defined in terms of a graph algebra, which allows our system to induce a compact CCG lexicon. We introduce an expectation maximisation algorithm which we use to filter our lexicon down to 2500 lexical templates. Our system achieves a semantic triple (Smatch) precision that is competitive with other CCG-based AMR parsing approaches.
Assessment Tool for Environmental Management System Performance According to the ISO 14001

The present paper is concerned with a statistical approach involving latent and manifest variables applied in order to assess the Environmental Management System performance. The main idea is to develop an assessment tool in order to measure the Environmental Management System practices performances (which are divided into seven segments: Context of the organization, Leadership, Planning, Improvement, Support, Operation, and Performance Evaluation) described in the ISO14001 standard, enabling the company to characterize her performance regarding to the ISO 14001 standards. For this, we conceptualize a structural equation modeling (SEM) which describes various causal connections between the Environmental Management requirements. The SEM’s resolution is based on the Partial Least squares (PLS) method and the implementation is running in the XLSTAT software. The obtained results could be examined in order to plan the improvements and develop an action plan. It is necessary to control Environmental Management System performance to ensure that it is either good enough, or that something is being done to improve it.
