Within text categorization and other data mining tasks, the use of suitable methods for term weighting can

bring a substantial boost in effectiveness. Several term weighting methods have been presented throughout

literature, based on assumptions commonly derived from observation of distribution of words in documents.

For example, the idf assumption states that words appearing in many documents are usually not as important

as less frequent ones. Contrarily to tf.idf and other weighting methods derived from information retrieval,

schemes proposed more recently are supervised, i.e. based on knownledge of membership of training documents

to categories. We propose here a supervised variant of the tf.idf scheme, based on computing the

usual idf factor without considering documents of the category to be recognized, so that importance of terms

frequently appearing only within it is not underestimated. A further proposed variant is additionally based on

relevance frequency, considering occurrences of words within the category itself. In extensive experiments on

two recurring text collections with several unsupervised and supervised weighting schemes, we show that the

ones we propose generally perform better than or comparably to other ones in terms of accuracy, using two

different learning methods.


A liner for use with a respiratory mask having a face-engaging portion, such as a CPAP mask, includes a body constructed from an absorbent material, the body having an outer edge, an inner edge, and an opening bounded by the inner edge. A perimeter of the outer edge is larger than a perimeter of the face-engaging portion of the respiratory mask for forming an extending portion of the body, and the liner is configured to be releasably held by the mask and a user's face such that the outer edge extends beyond the face-engaging portion.


The lateral habenula, a regulator of neuromodulator release, contains a semi-autonomous molecular clock whose significance is unknown. Here, using zebrafish, we investigate the contribution of this clock to change in internal state that is triggered by an aversive stimulus. We focused on the alarm pheromone, Schreckstoff, whose effects vary in a circadian manner. Disruption of habenula clock function, by selective expression of a truncated clock gene (∆CLK), altered the effects of Schreckstoff such that larval responses in the day resembled those at night. Acute responses, including immediate change in swim speed, were unaffected, whereas extended behaviours such as freezing in a novel environment and dark avoidance, were reduced. Circadian behaviours that are under the control of the pineal clock, such as locomotion and sleep, were unchanged. These findings suggest that the habenula clock can act independently to influence the internal state induced by an aversive stimulus.

To evaluate the effectiveness of a Marine Protected Area (MPA) as a conservation strategy for an endangered species, it is important to know to what extent the population is using the MPA. In the Wider Caribbean Region, the use of MPAs is driven by the SPAW Protocol of the Cartagena Convention. Belize has been a leader in implementing goals set forth in the SPAW Protocol, including establishment of MPAs targeted towards the Antillean manatee, Trichechus manatus manatus. However, evaluation of the effectiveness of this conservation strategy for protecting endangered manatees in Belize is lacking. As part of a long-term study (1999-2006), I used underwater video techniques to capture images of manatees encountered in the Drowned Cayes area near Belize City. Non-lethal boat scars were detected on 103 of the 233 manatee images captured on video. Due to this relatively high number of individually identifiable animals in the area, a database of known manatees is being developed and analyzed to determine the parameters of the manatee population using Swallow Caye Wildlife Sanctuary (SCWS) and the Drowned Cayes. SCWS is a MPA established in the Drowned Cayes area in 2002, and the only MPA in the vicinity of Belize City where manatee mortality due to boat collisions is high. If manatees previously hit by boats have learned to seek shelter within SCWS, I would expect the proportion of scarred animals to be higher within the boundaries of the MPA. To date, the probability of capturing a scarred manatee within the boundaries of SCWS (probability =0.44, n=43 events, 19 scarred) is equal (G2=0.00) to the probability of capturing a scarred manatee outside SCWS (probability=0.44, n=190 events, 84 scarred). Continuation of this study is necessary to determine the parameters of the manatee population using SCWS and to evaluate the effectiveness of this MPA.


Viscose-grade cotton linters (DPw = 1135) were converted to viscose by the emulsion xanthation technique. Two variables—namely, substitution level and xanthation time—were considered insofar as their influence on the uniformity of substitution with regard to chain length was concerned. The stable diethylacetamide derivatives were prepared by reaction with diethylchloroacetamide and fractionally precipitated from aqueous 2-chloroethanol. The DPw and degree of substitution (DS) of the individual fractions were determined. The results in each case indicated that the longer chains were more highly substituted than the shorter chains. For a constant xanthation time (6 hr.), uniformity in substitution improved with increasing substitution level. For a constant CS2:cellulose ratio (1.48), uniformity increased with xanthation time. A mechanism is suggested which accounts for these phenomena.


Mindlin plate theory has been the choice for the analysis of high frequency vibrations of piezoelectric quartz crystal resonators, which utilize electroded crystal plates vibrating at the thickness-shear and overtone modes to achieve frequency generation functions and applications. For this purpose, Mindlin plate equations have been simplified, modified, and corrected to accommodate the actual geometry, structural complications, practical boundary conditions, and various bias fields such as temperature change and initial stresses. Accordingly, the correction of Mindlin plate theory should also include complications through factors which adjust the thickness-shear frequencies to the exact three-dimensional solutions from earlier studies with the first-order plate equations. In recent studies, correction factors for equations up to the third-order theory have been introduced and they have the capability to make the cut-off frequencies for the thickness-shear modes accurate up to much higher-orders and improving the accuracy of the extensional mode groups also. These correction factors are derived based on the general principle of comparison and matching of exact frequencies of interested vibration modes in the coupled two-dimensional equations, and the inclusion of structural complications such as electrodes is an natural extension of the derivation with practical importance. In this study, we consider the effect of thin electrodes through their mass loading formulation by adding the mass ratio in the inertia terms as demonstrated by Mindlin and others. Consequently, a set of frequency equations for both thickness-shear and extensional modes are established with the inclusion of mass ratio of electrodes. These equations are solved numerically for mass ratios to obtain the corresponding correction factors which have been modified by the presence of electrodes. These correction factors can be utilized in the improvement of applications of the higher-order plate equations with the finite element implementation, which remains as one of the reliable tool in the precise analysis and design of quartz crystal resonators. The derivation of these correction factors can be further incorporated into nonlinear equations of piezoelectric solids.


Stirring of a THF solution of [W(η-C5H5)(CO)3(σ-trans-CH2CHCHCCMe)] with RXH (RXH = H2O, MeOH, NH2Bui) over silica or Florisil gel leads to a new carbonylation reaction to give [W(η-C5H5)(CO)2(η3-3-syn-RXCO-3-anti-Me-1-vinylallyl)] compounds in moderate yields, providing direct evidence for a tandem 1,3-metal shift across conjugated allyl and alkyne bonds.


There is great interest in investigating structural and activity relationships between conotoxins and their biological targets. The information obtained using these techniques has added to our knowledge of how these molecules interact with receptors, and allowed us to pursue the synthesis of more selective and/or potent analogues. Chapters 1 and 2 serve as an introduction to the field of conotoxin research, and to the diversity of biological targets for which they are selective. They also give a general introduction to solid-phase peptide synthesis, the powerful tool used for the synthesis of peptides and analogues used in this study. Chapter 3 contains the materials and methods used throughout this thesis. Common methods used throughout the thesis have been included in one chapter to help minimise repetition. A brief introduction to many of the specialised techniques encountered is also given. Chapter 4 involves the SAR study of a-Ctx [A10L] PnIA through alaninescanning mutagenesis. Peptides were synthesised and their affinity for the a7 nAChR evaluated in a rat brain homogenate, and potency was determined with electrophysiological studies. This provides information as to which residues are important for interacting with the a7 subtype of the neuronal nicotinic acetylcholine receptor. Preliminary structural studies were performed to determine whether structural changes accompanied any loss in affinity of the peptide to the receptor, to distinguish important interactions from structural perturbations. Chapter 5 probes the importance that the side-chain of position 10 has on affinity to the a7 nAChR. A series of seventeen point mutations were synthesised, with side chains containing aromatic, aliphatic, polar and charged residues. Previous work demonstrated that the side-chain at position 10 could discriminate between two different subtypes of the nAChR, therefore a functional screen was performed to estimate the activity and selectivity of these mutated peptides at different subtypes of the receptor. Chapter 6 describes the synthesis and structural studies of a-conotoxin ImII, a conotoxin that is functionally active at the a7 nAChR, but does not bind to the classical conotoxin binding site. It is the only a-conotoxin described to date that does not contain a proline residue at position 6, and makes an excellent candidate for structural studies. Chapter 7 investigates a novel method for the synthesis of conotoxins from the O-superfamily. These conotoxins all contain adjacent cysteine residues located between the second and third loops, making them excellent targets for synthesis by native chemical ligation of two peptide segments. This novel strategy was applied to synthesise chimeras of N-type VGCC selective CVID and P/Q-type VGCC selective MVIIC, two peptides that are pharmacologically well characterised. It is hoped that this methodology will enable synthesis of peptides that have either been difficult to synthesise or oxidise in the past. The overall aim of this thesis is to investigate the structure and activity of some disulfide-rich conus peptides, and determine the residues responsible for selectivity and affinity toward their biological target. The information obtained from this study will further our knowledge of how these peptides interact with these receptors and receptor subtypes. Subtype selective ligands can be used as pharmacological tools to dissect and characterise the roles individual subtypes play in the complex mixtures of receptors found in native tissues.


Hybrid Electrical Vehicles (HEVs) are developing nowadays faster because of the environmental condition changes happening because of the standard fuel vehicle transmissions. These Electric Vehicles had turned out to be cleaner solutions for nature or climate where their discharge emissions are to be condensed or decreased by transportation. However, this study can observe the configurations, elements, then varieties of HEVs to style a hybrid electric powertrain that ends up satisfying the fashionable Hybrid Electric Vehicle performance criteria. These standards can include or contain as a part of the whole, acceleration, braking controls, driving range, fuel economy & emission. In this paper dissimilar styles with types of different EVs were studied or examined in terms of the Battery State-of- Charge, Emission etc. In this Real time parameters with MATLAB/Simulink simulations are carried out to achieve the essential performance metrics.


The behavioral profile of aquatic animals exposed to diverse toxicants is considered as an index to estimate the degree and nature of stress experienced by the animals both in natural and in experimental conditions. Acute toxic effects and behavioral alterations induced by exposure of the freshwater crab Barytelphusa guerini to cadmium chloride reported after finding Lc50. Ten healthy specimens of the same size in each group were exposed to seven different concentrations of cadmium chloride (1.00, 1.25, 1.50, 1.75, 2.00., 2.25 and 2.50 µg/L) along with a control group for 0 to 96 hours. The exposed crabs exhibited hyperactivity, escape behavior, increased scaphognathite beating, topsy-turving reflexes, increased oxygen consumption, tendency of avoiding, hypersecretion of mucus and release of excess excretory product ammonia with increasing toxicant concentration and exposure time. Toxin induced alteration of studied behavior is an indicative of a possible shift in the overall physiological functions and biological activities, of this experimental animal in its natural habitat.


We present an analysis of a 37 ks observation of the supergiant fast X-ray transient IGR J17391−3021 (= XTE J1739−302) gathered with Suzaku. The source evolved from quiescence to a low-activity level culminating in three weak flares lasting ∼3 ks each in which the peak luminosity is only a factor of five times that of the pre-flare luminosity. The minimum observed luminosity was 1.3 × 1033 erg s−1(d/2.7 kpc)2 in the 0.5–10 keV range. The weak flares are accompanied by significant changes in the spectral parameters including a column density (NH =(4.1+0.4−0.5) × 1022 cm−2) that is ∼2–9 times the absorption measured during quiescence. Accretion of obscuring clumps of stellar wind material can explain both the small flares and the increase in NH. Placing this observation in the context of the recent Swift monitoring campaign, we find that weak-flaring episodes, or at least epochs of enhanced activity just above the quiescent level but well below the moderately bright or high-luminosity outbursts, represent more than 60% ± 5% of all observations in the 0.5–10 keV energy range making this the most common state in the emission behavior of IGR J17391−3021.


The WSA covers about 300,000 acres and includes the surface waters and much of the recharge area to some 27 named springs. These springs discharge an average of 71 million gallons per day. The study area is generally underlain by karst geology, characterized by sinkholes, caves, and springs. Generally, higher topographic regions in the west and south serve to recharge the Floridan Aquifer system that in turn feeds the springs and wetlands in the lower elevations in the central, northern, and eastern regions of the WSA.


Elementary school children and adults selected for significant pitch identification ability, so called "absolute pitch", were given two tasks to determine some of the characteristics of this skill. In a pitch-naming task, participants gave the note names for tones randomly selected from the chromatic scale either with a conventional piano or pure tone timbre. Naming accuracy was higher among the adults, on trials having the piano timbre, and for certain pitch categories (note names), reflecting more accurate identification of "white key" pitches. Analysis of errors indicated a strong bias towards certain pitch categories, again primarily the "white key" pitches, in both children and adults. Comparison subjects having similar musical training, but no absolute pitch, also showed these biases. In a pitch recognition task, participants were asked to detect additional exemplars of a target tone in an extended series of tones varying in pitch. While those with significant pitch naming skill were quite adept at this task as well, biases associated with pitch category were less apparent. These results suggest a distinction between pitch encoding and naming in those who excel in pitch identification.


Primary concern of people living in developing countries throughout the world is that of obtaining clean, microbiologically safe water for drinking purpose. Solar water disinfection (SODIS) is a simple, environmentally sustainable, low-cost water treatment method using solar radiation to destroy pathogenic bacteria present in the water. Therefore present study was performed in order to find out the effect of solar radiation on the occurrence of bacterial indicators in drinking water collected from common wells. Water samples were collected in sterile, transparent glass bottles from the five common wells in Nallur division, Jaffna, Srilanka and brought to the laboratory as early as possible for further examination. Glass bottles were kept under direct sunlight and samples were withdrawn from each treatment at 0, 3 and 6 hours intervals. Samples were enumerated for total aerobic bacteria, E.coli and faecal coliforms and while sampling temperature of water, temperature of the environment and the intensity of light were also measured. Transmission of sunlight through glass bottle was determined by spectrophotometer. Light intensity varied highly significantly from 9am to 3pm. Water temperature increased significantly only from 9am to 12noon only. Even though the light intensity decreased significantly from 12noon to 3pm, there was no significant variation in environmental and water temperatures. The present study showed when the mean light intensity increased from 56.8klx to 2717klx, E.coli and feacal coliform were completely inactivated in 80% of well water samples with increasing water temperature(27.5oC to 50.5oC) and the environmental temperature(28oC to 34oC). The colourless glass bottle(Pyrex) transmitted sunlight at high percentage(80%). When exposure time to sunlight increased total aerobic bacterial number, E.coli and faecal coliform numbers were significantly reduced with increasing water and the environmental temperatures. E.coli and Faecal coliform were absent in all samples after 6 hours of treatment. Exposing of water to direct sunlight for 6 hours was an effective and cheep method of disinfection to obtain microbiologically safe drinking water at household level during hot and sunny climate seasons. Key words: Solar radiation, Disinfection, Bacterial indicators, Drinking water


There is a growing interest in the influence of vitamin D on ovine non-skeletal health. The aim of this study was to explore the relationship between pre-mating vitamin D status, as assessed by serum concentrations of 25-Hydroxyvitamin D [25(OH)D; comprising D 2 and D 3 ] and subsequent reproductive performance of genetically unimproved Scottish Blackface (UBF), genetically improved Scottish Blackface (IBF) and Lleyn ewes kept under Scottish hill conditions. 25-Hydroxyvitamin D 2 (25(OH)D 2 ) and 25-Hydroxyvitamin D 3 (25(OH)D 3 ) concentrations were determined in serum samples harvested in November from ewes grazed outdoors. There were no significant differences in 25(OH)D 2 concentrations amongst the 3 genotypes. Lleyn ewes had significantly higher 25(OH)D 3 and 25(OH)D concentrations than both Scottish Blackface ewe genotypes, whereas these vitamin D parameters did not differ significantly between the UBF and IBF ewes. Concentrations of 25(OH)D 3 and 25(OH)D were positively associated with subsequent birth weights of singleton and of twin lamb litters. No significant associations between vitamin D status and number of lambs born or weaned per ewe were found. This study demonstrates that concentrations of cutaneously-derived 25(OH)D 3, but not of orally consumed 25(OH)D 2 , differed between breeds. The positive association between ewe vitamin D status and offspring birth weight highlights the need for further investigations. The two forms of vitamin D, namely D 2 and D 3 , can be obtained from diet or during sunlight exposure. Vitamin D 2 and its precursor can be found in fungal resources, such vitamin D status of contrasting genotypes, all in the same flock, and breeding outcomes was investigated. activated with 3 ml of ethyl acetate, 3 ml of methanol and 3 ml of distilled water. After addition of a mixture of supernatant (approximately 300 µ l) from protein precipitation and 1 ml 0.4 M K 2 HPO 4 , the plate was washed with 3 ml of distilled water and 2 ml of 40% methanol sequentially and eluted with 1.5 ml of acetonitrile 29 . After evaporating to dryness, samples were derivatized by 2 additions of 25 µ l of 0.1 mg/ml DMEQ-TAD (4-[2-(3,4-Dihydro-6,7-dimethoxy-4-methyl-3-oxo-2-quinoxalinyl)ethyl] − 3 H -1,2,4-triazole-3,5(4 H )-dione; Abcam, UK) in ethyl acetate 30 . After evaporation to dryness, derivatized extracts were reconstituted in 25 µ l of 60:40 (vol:vol) methanol and 0.1% formic acid:water for HPLC-MS/MS analysis. To investigate differences in vitamin D concentrations [25(OH)D 2 , 25(OH)D 3 and total 25(OH)D (addition of 25(OH)D 2 and 25(OH)D 3 )] between breeds and amongst genotypes, the ewe breed/genotype, ewe age, pre-study system, ewe pre-mating weight, ewe pre-mating CS, sire of the ewe, number of lambs weaned and weaned litter weight in the last breeding cycle were the factors considered in the maximal GLM models. In the GLM models used to examine ewe breeding outcomes, the number of lambs born in 2016 and the number of lambs weaned that year, were tested, in turn, as response variates, whilst 25(OH)D 2 /25(OH)D 3 /25(OH) D concentration, ewe genotype, ewe age, management system (Hill grazing or Park grazing), pre-study system (CON or PLF), ewe pre-mating weight, ewe pre-mating CS, number of lambs weaned in the last breeding cycle (i.e. in 2015) and first winter feeding level were fitted in the maximal models. analysing D litter at birth, 25(OH) D 2 /25(OH)D 3 /25(OH)D ewe genotype, ewe management pre-study first win- ter ewe pre-mating ewe ram the maximal models GLM analyses. single- and twin-bearing ewes.The stepwise


Eight organisations received funding through the Health Workforce Australia (HWA) Expanded Scopes of Practice (ESOP) Nurses in the Emergency Department (NED) sub-project. The common goal was to improve ED flow and reduce waiting times for patients with non-life-threatening presentations while providing safe and high quality care. Each organisation implemented a different model of ESOP nursing care in the Emergency Department (ED). Three priority groups of patients were targeted. Three sites focused on patients presenting with mental health issues, aiming to deal with their specialised needs efficiently and effectively. One site initiated an ED review clinic staffed by clinical nurse consultants. Four sites aimed to enhance nurses' skills and confidence in dealing with common presentations. Two were based in rural areas and an important goal was to prevent unnecessary transfers to larger, regional hospitals. Two targeted paediatric patients with the goal of facilitating faster assessment, treatment and discharge.


Objective To observe the therapeutic effects of high-dose cytarabine (HD-Ara-C) in the treatment of patients with remission of acute myeloid leukemia (AML).Methods 29 cases with AML were randomly divided into treatment group (15 cases) and control group (14 cases).Patients in treatment group were carried HD-Ara-C intravenously on the first,third and fifth day,at least three hours,once or twice per year on the basis of routine chemical therapy while patients in control group were only carried routine chemical therapy.The disease-free survival (DFS) after the first,third and fifth year between two groups were compared.Results The difference of DFS after the first,third and fifth year between two groups was significant (P0.01).Conclusion HD-Ara-C has better therapeutic effect for patients with forced treatment after the remission of AML,which can prolong the time of DFS.


The study was conducted in order to establish and describe the mangrove community and vegetation of the mangrove forest in Alabel and Maasim, Sarangani province. It was evident that the studies for mangrove vegetation were really few in Sarangani bay. Thus, this study will serve as baseline information. Sampling plots (10m x 10m) were established into sea ward, middle ward and landward. Individual plants found within the plot were identified and counted. Mangrove vegetation analyses were determined using relative density, relative frequency, relative dominance and importance value. Community structure was analysed using multivariate analysis performing non-metric multidimensional scaling (nMDS), cluster analysis and one way ANOSIM. Mangrove communities in Alabel and Maasim, Sarangani province have identified 12species; A. marina, L. racemosa, P. acidula, A. floridum, X. granatum, B. gymnorrhiza, B. cylindrical, C. decandra, C. tagal, R. apiculata, R. mucronat andS. alba out of 39 true mangroves reported in the Philippines. Vegetation analysis in Alabel showed that species with the highest importance value wasA. marina (84.72%) and S. alba (158.72%) in Maasim sampling site. Cluster analysis showed moderate similarity among plots observed from the same site than plots from different sites. All the 21 sampling plots in Alabel and 20 in Maasimwere clustered based on similarities and formed into 3 groups with 40% similarity. Data ordination in nMDS revealed that characteristic similarity of same sites was analogous with ANOSIM of (R=0.317, P=0.001) but very minimal similar characteristics were observed in Alabel sampling plots to Maasim sampling plots. Results shows A. marina and S. alba as species with highest importance value with mangrove structure showing no distinct characteristics on the two sites.


The reaction of N-tosyltryptamines with thioortho esters, leading to 1-thiosubstituted tetrahydro-beta-carbolines under modified Pictet-Spengler conditions, is described. The 1-heterosubstituted beta-carbolines furnished 1-substituted beta-carbolines upon reaction with Grignard reagents and silyl derivatives under Lewis acid promotion. [reaction: see text]


Private equity and venture capital (PE/VC) are efficient resource allocation systems that provide equity capital to selected entrepreneurs, industries or firms that contribute to advance the economic welfare of society. Private equity and venture capital firms act as a catalyst for initiating, consolidating, professionalizing, growing and globalizing their portfolio companies, and in doing so, they increase their competitiveness and expand their operations in regional and global markets. They create an invaluable ecosystem based on innovation, entrepreneurship and the detection of business opportunities, building local talent and setting up the pillars of new growing industries diversifying countries' economies. From 1999 to 2005 the internet bubble and several economic crises impacted Latin America, collapsing private equity and venture capital activity. Moreover, the confidence of limited partners (LPs) in the fund managers (GPs, general partners) sank. Thanks to the fast growing internal demand of Brazil and the low economy cycle in developed countries, the appetite for private equity assets in emerging markets and in Latin America raised, creating the opportunity for successful exits. However, few success cases have been seen outside Brazil. Why the number of exits in Chile has been limited? What are the drivers of success? How is it possible to accelerate the development of PE/VC given the benefits they provide to the economy and the society? This document answers these questions identifying the most important factors affecting the development of private equity and venture capital. All the factors are linked together and form part of an ecosystem; they are not independent parts that can be studied separately. This ecosystem is modeled be mean of a framework, where the interactions among these factors are defined and their impact is explained in detail. Through the analysis of the model of private equity and venture capital developing factors two main conclusions are extracted: first, the development of PE/VC is a continuous learning process; positive actions implemented now will have a visible impact in the medium or long term. Second, success is the main driver of the PE/VC development as it has a positive amplifying effect in the whole ecosystem. However, success is one of many other factors, and all of them must be considered since all are interconnected. The more positive actions are put into action from all the different factors, the more success cases will be created and as a consequence, the development will be accelerated, creating a synergic reinforcing loop.

Digital Image captioning field deals with the concept of interpreting a given image by the application of different Artificial Intelligence (AI) based algorithms. These kind of systems always considered the input in the form of image and replying with an output representing some text or speech samples. This output explains the content present in the image. These kind of automated systems proven good in the areas like medical image processing, online review systems, speech conversion for visually impaired persons etc. This paper represents a comparative study among four different AI models: Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM) and kNN (k-Nearest Neighbor) in context of image captioning activity. Random scenes in the form of input images has been consider to show the part of diverse nature of these algorithms. It has been observed that SVM classifier outshine as compared to rest of the models with the overall accuracy of 98%.


Informal documentation contained in resources such as Q&A websites (e.g., Stack Overflow) is a precious resource for developers, who can find there examples on how to use certain APIs, as well as opinions about pros and cons of such APIs. Automatically identifying and classifying such opinions can alleviate developers' burden in performing manual searches, and can be used to recommend APIs that are good from some points of view (e.g., performance), or highlight those less ideal from other perspectives (e.g., compatibility). We propose POME (Pattern-based Opinion MinEr), an approach that leverages natural language parsing and pattern-matching to classify Stack Overflow sentences referring to APIs according to seven aspects (e.g., performance, usability), and to determine their polarity (positive vs negative). The patterns have been inferred by manually analyzing 4,346 sentences from Stack Overflow linked to a total of 30 APIs. We evaluated POME by (i) comparing the pattern-matching approach with machine learners leveraging the patterns themselves as well as n-grams extracted from Stack Overflow posts; (ii) assessing the ability of POME to detect the polarity of sentences, as compared to sentiment-analysis tools; (iii) comparing POME with the state-of-the-art Stack Overflow opinion mining approach, Opiner, through a study involving 24 human evaluators. Our study shows that POME exhibits a higher precision than a state-of-the-art technique (Opiner), in terms of both opinion aspect identification and polarity assessment.


Nb3Sn magnets with operating fields of 15-16 T are considered for the LHC Energy Doubler and a future Very High Energy pp Collider. Due to large coil volume, high critical current density and large superconducting (SC) filament size the persistent current effect is very large in Nb3Sn dipoles al low fields. This paper presents the results of analysis of the persistent current effect in the 15 T Nb3Sn dipole demonstrator being developed at FNAL, and describes different possibilities of its correction including passive SC wires, iron shims and coil geometry.


Objectives: We aimed to investigate the effect of CPAP on arterial stiffness, 24 hour ambulatory blood pressure and ventricular vascular coupling compared with sham treatment in patients with severe obstructive sleep apnea (OSA). Methods: Severe OSA was defined as an apnea-hypopnea index (AHI) > 30.. This 3-month, prospective, single-center, randomized, sham-controlled trial analyzed 52 patients with severe OSA. Patients were randomly assigned (1:1) to receive either CPAP or sham treatment for 3 months. The change of PWV, variables of 24 hour ambulatory blood pressure, and ventricular-vascular coupling over the 3-month period were investigated. Results: After 3 months follow-up, the PWV in the CPAP group at follow-up decreased considerably (7.2 ± 1.0 m/s) compared to either their baseline value (8.0 ± 1.3 m/s; p < 0.001) or their corresponding value (8.1 ± 1.0 m/s; p = 0.004) in the sham-treated group. In terms of 24-hour ambulatory blood pressures (BPs), night-time diastolic BPs and mean diastolic BPs at the 3-month follow-up in the CPAP group were significantly lower than the baseline values before randomization. However, these BP lowering effects were not shown in the sham-treated group. Baseline values of ventricular-vascular coupling were similar in both groups. In the CPAP group, arterial elastance at rest, 25 watts, and 50 watts of exercise decreased significantly after the 3-month treatment. Finally, the ventricular-vascular coupling index at rest decreased considerably in the CPAP group. Conclusion: In patients with severe OSA, CPAP treatment for 3 months improved arterial stiffness, night-time diastolic BP and ventricular-vascular coupling.

Background: Heart failure remains a significant socioeconomic burden and leads to critical health problems due to its high mortality and hospitalization rates. Therefore, proper treatment of heart failure is very important in terms of long-term prognosis and quality of life.Current Concepts: The use of evidence-based drugs, intervention treatment, and patient education are essential recommendations to improve the prognosis of heart failure. However, these recommendations of treatment guidelines are not well implemented in actual clinical situations. A more realistic solution can be sought considering the domestic situation. First, it is necessary to improve public awareness of the disease. It is also necessary to actively educate medical personnel, including primary care doctors. Second, efforts to improve clinical inertia or neglect of treatment of medical personnel are needed. For a systematic treatment approach, developing performance indicators in heart failure management are necessary, which can be a realistic and suitable alternative to the domestic clinics.Discussion and Conclusion: Applying a well-proven treatment to patients with heart failure should be essential, which is not an option in actual clinical practice. To solve this problem, social attention and efforts, more grand decisions by academic societies, and creative concerns from public institutions should be necessary in the face of the so-called heart failure epidemic around the world and in Korea.


Living organisms possess biological clocks that resonate with environmental cycles in light, temperature, and food availability. Recently, circadian oscillations in the redox state of peroxiredoxin have been described as an additional non-transcriptional timekeeping mechanism. Of note, this redox cycle is conserved in both prokaryotes and eukaryotes. How the classical "transcription-translation feedback loop" model and this redox oscillation are related is still poorly understood. In this minireview, we describe the most recent evidence pointing to cross-talk between the circadian clock and the redox status of the cell.


A method for simultaneous determination of 20 Perfluorinated alkyl substances( PFAS) in animal liver using Qu ECh ERs and HPLC-MS / MS technique was developed. The samples were extracted with 0. 1%hydrochloric acetonitrile and cleaned up with C18,N-Propylethylendiamine( PSA) and graphitized carbon blacks( GCB). The analytes were separated by a reversed phase C18 column and gradiently eluted with a mixed solution of 5 mmol / L ammonium acetate methanol and 5 mmol / L ammonium acetate. The samples were quantified using isotope internal standard and external standard with the matrix matched standard calibration curve method. Good linearity was obtained for all the 20 PFAS at the concentration of 0. 1- 10 μg / L with the linear correlation coefficients more than 0. 9995. The limits of detection( LOD) and the limits of quantification( LOQ) for PFAS were 0. 05- 0. 2 μg /kg and 0. 4- 0. 5 μg /kg,respectively. The recoveries at three different concentration levels( 0. 5,2 and 5 μg / kg) were in the range of 70. 3%- 108. 1%. The repeatability expressed as relative standard deviations( RSD) was ranged from 2. 1% to 11. 9%( n = 6).

The experimental study on single mineral flotation showed that the most appropriate flotation separation pH values of water glass in the scheelite, fluorite and calcite were 9~10. The most selective flotation separation for scheelite was using water glass and sodium carbonate together. The flotation solution chemical analysis showed the major element inhibiting calcite is Si(OH)4. While SiO(OH)3- exerts inhibitory effect on fluorite and scheelite. The addition of metal ions in aqueous solution changes the content of effective components enhancing the capacity of water glass selective inhibition.


. The purpose of the paper is to characterize the dimension of sub- linear Higson corona ν L ( X ) of X in terms of Lipschitz extensions of functions: Theorem 0.1. Suppose ( X,d ) is a proper metric space. The dimension of the sublinear Higson corona ν L ( X ) of X is the smallest integer m ≥ 0 with the following property: Any norm-preserving asymptotically Lipschitz function f ′ : A → R m +1 , A ⊂ X , extends to a norm-preserving asymptotically Lipschitz function g ′ : X → R m +1 . One should compare it to the result of Dranishnikov [5] who characterized the dimension of the Higson corona ν ( X ) of X is the smallest integer n ≥ 0 such that R n +1 is an absolute extensor of X in the asymptotic category A (that means any proper asymptotically Lipschitz function f : A → R n +1 , A closed in X , extends to a proper asymptotically Lipschitz function f ′ : X → R n +1 ). In [5] Dranishnikov introduced the category ˜ A whose objects are pointed proper metric spaces X and morphisms are asymptotically Lipschitz functions f : X → Y such that there are constants b,c > 0 satisfying | f ( x ) | ≥ c · | x | − b for all x ∈ X . We show dim( ν L ( X )) ≤ n if and only if R n +1 is an absolute extensor of X in the category ˜ A . dimension asdim AN ( X ) . If X is cocompact and connected, then asdim AN ( X ) equals the dimension of the sublinear Higson corona ν L ( X ) of X .


Years ago, when there were many small farms, farmers were encouraged to diversify. With today's larger operations, there is more specialization and greater concentration in agriculture. For example, the largest 10 broiler companies account for 70 percent of the production and processing (Schrader et al., 1997). Increasing specialization and concentration is also apparent in the hog industry. The long-run trend has been for smaller farms to leave the industry, and statistics show a dramatic shift to larger, more specialized units and greater geographical concentration in the production of hogs (Boehlje et al., 1997). However, there is still a significant percentage of producers, especially in the Midwest, who produce both crops and hogs.


In recent years, plasma medicine has been rapidly developing as a new research field due to the establishment of stable formation technology of lowtemperature atmospheric pressure plasma [1]. However, the biological reaction processes induced by plasma irradiation are not fully understood with respect to their physicochemical behavior. In this study, the transport properties of reactive oxygen and nitrogen species (RONS) in cell membranes under electric field were investigated using molecular dynamics (MD). In this analysis, we constructed a lipid membrane model containing a variety of RONS. The lipid bilayer is composed of POPC (1-palmitoly-2-oleoyl-sn-glycero-3phosphocholine), a phospholipid that forms a typical biological cell membrane. The calculation conditions are as follows. The pressure was 1 atm, the temperature was 303 K, the time step was 2 fs, and the total simulation time was 5 ns. The applied electric field is from 0.1 to 0.5 V⁄nm and the number of windows is 37. The trajectories of each molecule were obtained from classical MD simulations. An umbrella sampling method was used to apply an artificial bias potential to obtain data in the region of high energy levels, which are often lacking [2]. AMBER18 was used for the present MD simulation of biomolecules. Figure 1 shows that the position-dependent diffusion coefficients of OH, HO2, and H2O2 are lower inside the membrane and higher in the water layer. There was no significant difference in these diffusion coefficients. On the other hand, O showed higher diffusion coefficients in the inner part of the membrane compared to RONS as described above. This result can be qualitatively explained by the polarity of RONS. In other words, non-polar molecules diffuse more easily inside the membrane than polar molecules. The membrane permeability of H2O2, which is larger than that of O atoms and OH molecules, was smaller than that of O atoms and OH molecules. This reason must be that the membrane permeability depends on the size of the molecule. The present membrane permeability coefficient at 0.3 V/nm was four times larger than that without electric field. As shown in Figure 2, the electric field slightly reduces the energy bias against RONS molecules in the membrane, which can be said to facilitate permeation. The formation of water channels at an electric field strength of 0.5 V/nm indicates that hydrophilic RONS are efficiently transported through the lipid bilayer of POPC. The differences in membrane permeability were observed depending on the retention area of RONS. In particular, most of the ONOOH penetrated the present membrane within 1.0 ns after channel formation.

The presence of two or more distinct local maxima in the power spectrum of radiation results under certain conditions in appearance of peculiarities in interferometer temporal signal. These peculiarities are manifested as a single coherent trough (minimum) in envelope of interferometer signal and as a (pi) -jump of phase of this signal in the point of envelope's trough. The coherent trough can be used as a measuring signal in the partial coherence interferometry. The conditions for observation of single coherence trough in envelope of interferometer temporal signal are discussed.


A philosophy need not be afraid of being out-of-date. Any true philosophy, untimely as soon as it is published, necessarily remains so, thus necessarily remains relevant. This is the case of Descartes' philosophy. But in the case of Cartesianism, there is more to it: Descartes' philosophy goes in quest of the decisive, the principle, the very first Beginning. And the philosophy in quest of the Beginning is, indeed, a radical and original philosophy: what keeps its interest to Descartes' project and, even nowadays, its relevance is the fact that it may be mistaken with the very project of philosophy. In this way what is new in the Beginning, which we think is the shape of the breaking-up, is the old, the oldest. Although Descartes claims for his novelty ('je serai obligé d'écrire ici en même façon que si je traitais d'une matière que jamais personne avant moi n'eust touchée', 'I shall have to write here as if I were dealing with a subject which nobody before me had ever handled'), he keeps coming back 'to the very prime moment of the Beginning', to the initial, original Beginning, that of the being: 'Mit dem cogito sum beansprucht Descartes, Heidegger says at the beginning of Sein und Zeit, der Philosophie einen neuen und sicheren Boden beizustellen'. Now, nothing is more untimely than the inaugural, nothing is more decisive than the foundation: if the relevance of Cartesianism does exist, it is the true one, the original one. So, even nowadays, we cannot philosophize without Descartes (even though some people would like to philosophize against Descartes).


Analysis of mutual information is important to wireless transmission over fading channels, and is usually done by assuming perfect channel state information (CSI) available at the receiver. In many practical applications, however, the CSI must be estimated by sending a limited number of pilot symbols and thus, can suffer from considerable inaccuracy. The influence of CSI inaccuracy on achievable mutual information, though analyzed in the past, is not well understood. The difficulty arises from the presence of a product term of signal and channel estimation error in the received signal model, and the lack of appropriate tools to determine its probability density function. This situation forces the adoption of a bounding technique in current literature by treating the product term either as a signal component or as a noise component. In this paper, we take a different methodology by accurately fitting the received signal with the multivariate Pearson's type-7 (MPT-7) distribution. The new results are simple in expression, very accurate as evidenced by simulation, and capable of directly revealing the dependence of the achievable mutual information on a particular channel estimator.


Fish populations were studied in the pre-delta of the Danube river under the circumstances of the general pollution as a result of the Yugoslavia war. This is the first paper concerning the presence of Gobius melanostomusmelanostomus population in the Danube. To determine this, we conducted an interspecies variability study that compared freshwater populations that were found from Braila to Galati, and to marine populations. Conclusions were found concerning the intra-specific variability within the Gobius melanostomus melanostomus community in the pre-delta area of the Danube (i.e. the Prut river mouth and Cotui Pisicit) as well as those existing in the Black Sea.


The purpose of this paper is to develop assessment framework for customer loyalty in quick-service restaurants. Building customer loyalty is a key factor in influencing repeat purchases in the designated restaurant. This framework used multi-grade fuzzy for assessment and importance performance analysis is used to identify the weaker attributes that need to be improved. The case study has been conducted in a quick-service restaurant. Based on the case-analysis promised and on-time service, attentive staff, and a range of foods are weaker attributes. This framework enables restaurant managers to identify and improve customer satisfaction, which will have a direct influence on customer loyalty.


The structure, dynamics, and strength of aqueous boehmite gels were studied by yield stress measurements and light scattering as a function of the particle aspect ratio and ionic strength. The yield stress was found to be a strongly varying function of the salt concentration. At low ionic strength, yield stress results from extensive double layers surrounding the rods, leading to a "colloidal glass". Addition of LiCl decreases the yield stress and enhances the particle dynamics in the gel when [LiCl] < 10mM. For 10 mM < [LiCl] < 75 mM, particle aggregation induces the formation of a space-filling heterogeneous network with fractal dimension d = 2.35, causing a rise in the yield stress and renewed freezing of the particle dynamics. When the LiCl concentration exceeds 75 mM, the yield stress decreases again and the now very turbid gels show syneresis. For the attractive rods, the peculiar salt dependence of the gel strength can be explained by polydispersity in interactions, caused by inhomogeneities in par...

A precise forecast is surely critical in stock prediction. Many people are increasingly investing in stocks in recent times; hence it is evident that prediction of stock prices is very crucial. Statistical, Machine Learning and Deep Learning models can be used to forecast Stock prices. In this paper, Statistical method SARIMA is used to predict stock prices. To improve the outcome of forecasting five Deep Learning models namely Single-Layer LSTM, Three-Layer LSTM, Bidirectional LSTM, CNN LSTM and Convolutional LSTM are used. In Single-Layer LSTM and Three-Layer LSTM models LSTM layers are used to give better output. Bidirectional LSTM is used to predict the prices not only based on the previous inputs but also upon the future inputs. CNN is combined with LSTM to capture the underlying abstract features in the input series. Convolutional LSTM is another variation of LSTM which helps to capture the features that contain convolution activity inside the LSTM cell. All the proposed models are validated using evaluation metrics like RMS, RMAE, MAE, R2-SCORE to determine the robustness of the every Deep Learning model used. For this paper, TCS stocks are considered. The proposed methods in this paper can be applied to any other company stocks for the forecasting their stock prices.


In Cheshire, England, across the River Mersey from Liverpool and hard by the Welsh border, lies historic Chester. Its ancient and medieval past still much in evidence, Chester boasts a well-preserved Roman amphitheater, an eleventh-century Anglican cathedral, and many blackand-white, half-timber buildings. In this city of approximately sixty thousand souls reside roughly five thousand Roman Catholics, who are ministered to by five churches. Here as elsewhere throughout Great Britain, on any given Sunday Roman Catholics are likely to outnumber Anglicans at worship. St. Francis Church is served by six members of a religious body whose official name is Ordo Fratrum Minorum Capuccinorum (O.P.M. Cap.). Founded in the sixteenth century by Matteo da Bascio (d. 1552), who wanted to return to the original simplicity of the order, this branch of Franciscans, the Capuchins, emphasizes poverty, austerity, and contemplative prayer. The Capuchins wear a brown habit with a pointed hood, whence derives the term for the espresso coffee with a cone of whipped milk known as "cappuccino." The Capuchins are "friars," a word that comes from the French frere and ultimately from the Latin frater. In contrast to monks, who live alone or in a monastery, these brothers are a fraternity of "seculars": "the world is their cloister," where they preach and engage in missionary work. All six friars who serve St. Francis Church and live in the adjacent friary are also priests. When the Franciscans first came to Chester in 1235, during the reign of King Henry II, they wore a gray habit made of undyed wool, giving them the nickname the "Grey Friars." Following three hundred years' residence in the city, they were expelled when Henry VIII dissolved the religious orders. Just before Christmas in 1858, two Capuchin Franciscan friars arrived in Chester from north Wales to take up the work that their predecessors had been forced to abandon. Four years later, the local bishop laid the foundation stone for a new church; but a series of disasters, starting with a builder's bankruptcy, followed a year later by a destructive earthquake, impeded the building's completion. In 1863 a hurricane reduced much of the nearly completed church to rubble. Twelve years later the church finally opened, replacing a temporary wooden building (Crispin Jones, St. Francis, Chester: Brief History of the Capuchin Franciscan Friars in Chester, n.p., n.d., 1-6). A high Victorian structure designed by the Liverpool architect James O'Byrne and capable of seating six hundred people, St. Francis Church is located on Grosvenor Street. This location is within Chester's medieval walls and near museums, shops, pubs, offices, and other churches. Together with the semi-gothic style, the reddish-brown sandstone used in the church's construction gives the building's exterior a dark, heavy, urban Victorian look. In the autumn of 2001 this somber public face was somewhat relieved by a bright yellow poster announcing in bold red letters an upcoming event called "SHOW STOPPERS," a church-sponsored evening of musical entertainment promising "All Your Favourite Songs from the Shows," for the price of just £3.50. The same exterior wall contained a more permanent feature as well: a statue of St. Francis in a niche above the front doors. St. Francis Church has four services on Sundays, including the principal service at 11 AM. A somewhat better attended service at 9 AM typically draws about 120 worshipers. This visitor to the church attended a weekday service, at which the priest who celebrated the mass was a former Anglican deacon and the son of a Church of England vicar. This friar had been a Roman Catholic priest for seven years. The church's interior was cluttered in the pre-Vatican II fashion with statues, shrines, and altars. The walls contained not only paintings and memorial tablets but also photographs and artificial flowers. In one corner at the rear a small gift shop sold such items as Christmas cards, candles, Advent calendars, crosses, and rosaries. …


Job-housing can reflect the life quality of Muslim migrants in the city. Muslim migrants have religion and unique lifestyle, which is not the general mobile population. Taking the Lanzhou Xiaoxihu region as an example, based on the GIS spatial analysis and principal component analysis, this paper introduces the distribution of jobs-housing, analyses the jobs-housing preference, gets the main conclusions: the distance between housing and job is relatively short, and the spatial matching degree of jobs-housing is higher in Xiaoxihu region. Choice preference to housing and job has a certain tendency, Housing preference to Muslim migrants is to be located in bigger house, poor housing facilities to meet the basic needs, cheaper rents, Muslim and religious community; Jobs preference to Muslim migrants is to be located in the surrounding of mosque restaurant industry practitioners and self-employment merchants work on ethnic food and food productions, construction workers of physical labor.


Submerged hollow fiber membrane system is widely used in water and wastewater treatment plants. One of the major problems of the microfiltration/ultrafiltration (MF/UF) process is membrane fouling. Few techniques have been developed to reduce membrane fouling and increase critical flux of the filtration process. In this study, membrane vibration was applied to improve the critical flux in a submerged hollow fiber MF system. A bench scale unit was especially built for this purpose and different vibrating speed was tested. The effect of the feed concentration and vibrating speed on the critical flux measurement were investigated. The critical flux was measured at different vibrating speeds varied from 0–500 oscillation per minute (opm) (5.83 Hz). The lowest critical flux was 15 L·m−2·h−1 when no membrane vibration was used and then increased gradually from 27 to 56 L·m−2·h−1 when the vibrating speed increased from 100 to 500 opm (8.35 Hz). A sharp drop in the critical flux was noticed when the concentration of feed suspension doubled from 5 g/L to 10 g/L. However, the increase in the critical flux was insignificant at higher feed concentration even when a high membrane vibrating speed was applied. This signifies that there is a limit for flux improvement in a vibratory system which is strongly dependent on the feed concentration.


To support equitable and ambitious teaching practices, classroom assessment design must be grounded in a research-based theory of learning. Compared to other theories, sociocultural theory offers a more powerful, integrative account of how motivational aspects of learning—such as self-regulation, self-efficacy, sense of belonging, and identity—are completely entwined with cognitive development. Instead of centering assessment within systems that support use of interim and end-of-year standardized tests, we argue for a vision of formative assessment based on discipline-specific tasks and questions that can provide qualitative insights about student experience and thinking, including their identification with disciplinary practices. At the same time, to be consistent with a productive formative assessment culture, grading policies should avoid using points and grades "to motivate" students but should create opportunities for students to use feedback to improve their work. We argue for districts as the locus for the design of such coherent curriculum, instruction, and assessment activity systems because districts have responsibility for curriculum, teacher professional development, and equity; and districts allocate resources for textbooks and assessment.


Given the long tradition of regional cooperation around the Baltic Sea, one could expect the Nordic-Baltic European Union (EU) members (these countries are known as the NB6; they are Sweden, Demark, Finland, Latvia, Estonia and Lithuania) to pool power in exerting influence in the EU. By drawing on the empirical evidence from the case studies on the Baltic Sea Strategy, the Stockholm Programme, and the EU climate negotiations, the author explains the mechanisms through which the members of the institutionalized coalition of NB6 interact in pre-negotiation stage in the EU Council, thus enhancing their bargaining power. However, we cannot speak of a permanent regional "bloc" in the EU because of member states' interest differences.

While I managed to traverse the security check relatively speedily by removing almost everything from my bag and sending it through the x-ray machine in a plastic tray, my colleague was not so lucky. She had already removed her laptop, coat and liquids, but the security staff insisted on taking her data projector from its case and subjecting it to intense scrutiny before allowing her through.


The pelagic larval duration (DPL) for 10 temperate cryptobenthic species belonging to three families: Gobiidae, Gobiesocidae and Blenniidae was investigated. Overall, the Gobiesocidae presented short DPLs varying between 11 and 18 days, the Gobiidae's DPL ranged between 14 and 39 days, and Parablennius pilicornis (Blenniidae) had an average of 33 days (range 31–37 days). Two subtypes of settlement marks were found among individuals of the same species.

Abstract The effect that resolution has on the calculated signal-to-noise ratio (SNR) of an emission line measured in the visible by a high resolution Fourier Transform Spectrometer is discussed. The resolution varies from a physically resolved profile (0.02 cm−1) to a shape dominated by the instrumental function (2 cm−1). The effects that incorporating inaccurate signal-to-noise ratios has on figures of merit for a FT-UV/VIS system is discussed.


Coal is found in every major geographic region throughout Alaska and in two offshore areas. Since about 1852 over 100 small mines have opened and closed. Last years production was almost entirely from one mine in central Alaska. Clearly the utilization of Alaska's abundant coal resources presents political, economic and technical problems that are far from solution.

Abstract While the accuracy of instruments and techniques in surveying is constantly being improved, the atmosphere through which we observe remains unchanged. In order to determine the adequacy of present methods of dealing with the bending of light rays, causes of refraction are analysed and data are assembled on the amount of bending and its variation, based on observed temperature gradients. The effects of this bending, both in magnitude and variation, are discussed in relation to trigonometric heighting, levelling, photogrammetry, triangulation, and high precision traversing, and the relevance to geodimeter and tellurometer observations is also noted.

The monitoring system (10, 11) comprises a first unit (11) associated to the distribution substation (5), wherein the first unit (11) is designed to generate activation codes (4), and a plurality of second units (10) associated to the panels (1), wherein each of the second units (10) is designed to inhibit operation of the respective panel (1) in the absence of the activation code (4) for a pre-set period. Furthermore, each second unit (10) is selectively activatable via a unique activation code(4) generated by the first unit (11). The antitheft and monitoring system is moreover configured to activate an individual panel (1) selectively by sending onto the connection line (L) the corresponding unique activation code (4) and detecting, via a measuring device (22), the characteristics of voltage and current of the individual active panel (1).


Cloud computing has gained a lot of hype in the current era and it is said to be the next big thing in the computer world after the internet. Cloud computing is using Internet for the tasks performed on the computer and it is visualized as the next- generation architecture of IT Enterprise. Cloud computing is attached to several technologies and the union of various technologies has emerged to be called cloud computing. Cloud Computing transfers the application software and databases to the enormous data centers, where the administration of the data and services may not be fully honest. This irreplaceable attribute poses many new security challenges which have not been well understood. In this paper, we discuss the mechanism that not only protect sensitive data by enabling computations with encrypted data, but also protect customers from malicious behaviors by enabling the validation of the computation result.


Median nerve neurapraxia associated with direct traumatic vascular injury to the brachial artery is extremely low. Brachial pseudoaneurysm could result in compression and elongation of the nerveleading to an ischemic injury. An early diagnosis of these injuries is essential to avoid complications and an improved prognosis could be expected under the correct management.


BACKGROUND Hair follicles and underlying adipose tissue show highly coordinated interaction through exchange of different signaling molecules. We conducted a study to investigate the quantitative and qualitative secretome profiling of Adipose Derived Stem Cells (ADSCs) from different zones of hair growth in patients with Androgenetic Alopecia (AGA).METHODSWe included 6 male patients, candidates for follicular unit extraction hair transplantation, all in early stage of AGA. 1mm punch samples of adipose tissue located beneath hair follicles of 3 scalp areas (alopecia, border-line and normal hair growth) and 1 periumbilical sample were analyzed.Samples were enzymatically digested, centrifuged, washed, and cell pellets were ceded and maintained in culture medium until reached monolayer. Conditioned media samples were thawed and analyzed with 41plex kit. Results were registered by Magpix device (Luminex platform) and calculated with xPonent software. We analyzed the levels of 35 signaling proteins.RESULTSThe level of Inteleukin-6 (IL-6) were significantly higher in the alopecia zone in comparison to the periumbilical and occipital, alongside with the levels of Vascular Endothelial Growth Factor (VEGF), Endothelial Growth Factor (EGF) and Eotaxin. The similar trend was found for Monocyte Chemotactic Protein-3 (MCP-3), Interferon gamma-inducible Protein-10 (IP-10) and Macrophage Inflammatory Protein - 1 alpha (MIP-1𝛼), while, on the other side, Monocyte Chemoattractant Protein-1 (MCP-1) level was the lowest in alopecia comparing to other zones. All other examined proteins did not shown changes in their expression level.CONCLUSIONHence, knowledge of differences in these signaling molecules expression will be essential for both, achieving therapeutic goals for hair loss conditions and shading more lights on the AGA etiology.


This paper investigates diverse policy experiences of enhancing agro-tourism in Korea. Since the campaign of "rural theme village" as a rural development strategy is closely related with the discussion of agro-tourism, this paper looks into past and recent streams of agro-tourism strategies pursued by the central government in Korea. This paper examines why agro-tourism has emerged as one of major rural development strategies in Korea. Along with a historical background of agro-tourism development in Korea, this paper presents the current and possible future characteristics of green tourism for rural community development in Korea. This paper also examines the perceived role of tourism in rural development. Special attention is paid to the ways in which the development of tourist attractions encourages changes in attitudes towards both rural resources assessment and entrepreneurship. Presenting success and failure stories, this paper also considers why the development of tourist attractions has been slow in rural areas of Korea, reviewing restraints, reservations, and problems identified during the last decade.

Women have become more important in the global market, not just as employees, but also as consumers, entrepreneurs, managers and investors. This paper aims to capture the managerial skills of women entrepreneurs in Dobrudgea's rural area and the difficulties that women entrepreneurs are facing, the gender differences and gender diversity in business, as well as their impact on the economy. By approaching this theme, we intend to highlight the problems faced by women both in terms of concepts and education by analyzing the employment rate by age, status and education level. Although women are still a minority in entrepreneurship and entrepreneurial skills and women workforce in rural areas are underused, in recent years there has been a considerable increase worldwide in the number of women who start and run their own business. Moreover, it is a general characteristic of Eastern European countries, which have the lowest levels of women's participation in entrepreneurial activities.


In 1997 the prime minister, Tony Blair, coined the phrase "joined-up government."1 When policy problems didn't fit neatly into departmental and ministerial boundaries the idea was to collaborate on and coordinate aligned approaches and messaging.2

Unfortunately, the recent response to the NHS workforce crisis is the antithesis of this, across departments and a confusing array of national NHS arm's length bodies created by the 2012 Health and Social Care Act.3 Let me take you on a quick tour.

NHS England's new chair, David Prior, stated on arrival that the three biggest challenges facing the NHS over the next 10 years were "prevention," "integration," and "technology."4 He has long experience in ministerial, regulatory, and NHS board roles. Yet, bizarrely, he didn't mention the …

W e describe the case of a 71-year-old man who was being followed as an outpatient for type 2 diabetes , hyperlipidemia, hypertension, and asthma. He was a past smoker with a BMI of 25.6 kg/m 2. Because he had only mild wheezing at night, he was not under medical treatment for asthma. As his level of HbA 1c remained between 6.6 and 6.8% under treatment with 2.5 mg gliben-clamide, 30 mg pioglitazone (an insulin-sensitizing drug) was added to his treatment. Several days later, he noticed that his wheezing had disappeared. The pulmonary function tests showed improvement of forced vital capacity from 2.33 to 3.02 l and forced expiratory volume in one second from 1.46 to 2.03 l, one month after the start of treatment with pioglitazone. No significant change was observed in the serum level of total IgE (76 vs. 66 IU/ml, reference interval Ͻ250 IU/ml). The level of HbA 1c (reference interval 4.3–5.8%) also decreased from 6.7 to 5.9% 3 months later. In this patient, pioglitazone seemed to be effective for both diabetes and asthma. Before treating this patient, we had treated another man with diabetes and asthma with pioglitazone. He had been on fenoterol hydrobromide by mouth and beclomethasone dipropionate by inhalation. Several days after he was started on 15 mg pioglitazone, he stopped wheezing and coughing. Pioglitazone was discontinued 6 months later because his level of HbA 1c had not decreased significantly, but his respiratory symptoms recurred. As this patient did not undergo pulmonary function tests, we had no objective evidence of the improvement of his asthma. Based on the findings obtained from these two patients with diabetes and asthma, we suppose that pioglitazone may ameliorate symptoms of asthma. Pio-glitazone is one of the thiazolidinedione compounds that have been used as anti-diabetic drugs (1). Recent studies have revealed that thiazolidinedione compounds also have various nonhypoglycemic effects , such as anti-inflamatory, anti-atherosclerotic, and anti-cancer effects, in cultured cells and experimental animal models (1,2). Although some of their effects are mediated through activation of the peroxisome proliferator–activated receptor -␥, an alternative mechanism has also been suggested (3). Thiazolidinedi-one compounds suppress the activation of macrophages and reduce nitric oxide and inflammatory cytokines, such as tumor necrosis factor-␣, interleukin-1␤, and interleukin-6 (4,5). In asthma, many mediators secreted from macrophages, mast cells, neutrophils, lymphocytes, and eosinophils are known to contribute to its pathogenesis. Pioglitazone may suppress the production of some of …

This study introduces a water index coined RWAAR: Rapid Water Analysis Algorithm for Response and Recovery for rapid flood detection using only freely available Sentinel-2 imagery. RWAAR exploits differences in spectral signatures of water, clouds, soil, concrete, asphalt, and vegetation in the following Sentinel-2 bands: band 2 (blue), band 8a (NIR), and band 11 (SWIR) to automatically extract pixels containing surface water. RWAAR was used to map flood inundation from Hurricane Ian using Sentinel-2 Level-2A imagery that was collected on September 30th, 2022. When compared to manually classified NOAA very high-resolution aerial imagery there was a 94.4% match. Current indices, NDWI and MNDWI were also tested and then compared to the NOAA imagery. For this location, NDWI had only a 61.3% match while MNDWI had a match of only 53.2%; however, more testing is needed and ongoing.


We prove a conjecture of Willis saying that for each f in the Volterra algebra the sequence (‖fn‖)n is a weight sequence which is regulated at 1.


In sports, dancing and playing music, it is important to achieve correct body movement as it greatly affects performance. However, matching one's movement with ideal movement is fundamentally difficult, because we do not have a detailed perception of our own body movement. In this study, we propose to present "rotary switch feeling" feedback as a new haptic cue. A periodical ticking sensation, like that of a rotary switch, can be presented at each joint so that the user vividly perceives his/her movement. This paper presents a simple mechanical prototype that is attached to the elbow.


The goal of this work is to understand how the sequence of a protein affects the likelihood that it will form an amyloid fibril and the kinetics along the fibrillization pathway. The focus is on very short fragments of amyloid proteins since these play a role in the fibrillization of the parent protein and can form fibrils themselves. Discontinuous molecular dynamics simulations using the PRIME20 force field were performed of the aggregation of 48‐peptide systems containing SNQNNF (PrP (170–175)), SSTSAA (RNaseA(15–20)), MVGGVV (Aβ(35–40)), GGVVIA (Aβ(37–42)), and MVGGVVIA (Aβ(35–42)). In our simulations SNQQNF, SSTTSAA, and MVGGVV form large numbers of fibrillar structures spontaneously (as in experiment). GGVVIA forms β‐sheets that do not stack into fibrils (unlike experiment). The combination sequence MVGGVVIA forms less fibrils than MVGGVV, hindered by the presence of the hydrophobic residues at the C‐terminal. Analysis of the simulation kinetics and energetics reveals why MVGGVV forms fibrils and GGVVIA does not, and why adding I and A to MVGGVVIA reduces fibrillization and enhances amorphous aggregation into oligomeric structures. The latter helps explain why Aβ(1–42) assembles into more complex oligomers than Aβ(1–40), a consequence of which is that it is more strongly associated with Alzheimer's disease.

Objective
To explore the clinical effect of composite mesh for repairing massive abdominal wall defect after abdominal wall tumor resection.

Methods
The clinical data of 55 patients with massive abdominal wall defect after abdominal wall tumor resection in the Fourth Affiliated Hospital of Xinjiang Medical University from February 2015 to August 2017 were retrospectively analyzed, they were divided into the experiment group (n=35) and the control group (n=20) according to the different mesh implanted. The two groups underwent abdominal wall tumor resection, the experiment group was implanted with Johnson Proceed mesh, the control group was implanted with Bard Composix Kugel mesh. The clinical parameters, pain degree at different time before and after surgery, the situation of healing of the incision, complications, tumor recurrence and metastasis in the two groups were compared.

Results
There was no significant difference in time of implanting mesh and postoperation spontaneous activity time between the two groups (P>0.05). The visual analogue score (VAS) from 12 hours to 7 days of postoperation gradually decreased in the two groups (P 0.05). After suture removed, the wounds all reached the first stage of healing, there was no significant difference in the incidence of total complications between the two groups (P>0.05). The follow-up period was 1 year, there was one case of tumor recurrence in the experiment group, one case of distant metastasis in the control group. The abdominal wall repair material was smooth, and no adhesion between the abdominal wall repair material and the intestinal tube was observed in the two groups.

Conclusion
The clinical effect of restoration and reconstruction of massive abdominal wall defect after abdominal wall tumor resection using Johnson Proceed mesh or Bard Composix Kugel mesh is good and safety.

Key words:

The purpose of the present invention is to appropriately display secondary information on a head-mounted display in relation to primary information displayed on a main display device even when a wearer moves or takes their eyes off the main display device. In order to achieve the above purpose, this collaborative head-mounted display system calculates the positional information of the head-mounted display wearer's gaze with respect to the primary information from a camera image acquired from the head-mounted display and the position of the head-mounted display wearer's gaze with respect to the camera image. The collaborative head-mounted display system then selects and displays the secondary information associated with the calculated positional information, and changes how the secondary information is displayed depending on whether or not the wearer is looking at the primary information.


In recent years, the implementation of renewable energy sources has been growth dramatically due to their numerous advantages. Among different renewable resources, the Photovoltaic (PV) system is one of the most renowned renewable sources due to existence of a great amount of solar radiations that eases expansion of PV systems. Notwithstanding, several types of faults, undesirable islanding, etc., have involved PV systems in great challenges. In this paper, a real-time differential scaling method is developed to detect the islanding events in PV systems. In the proposed approach, only the voltage signal of PV arrays is used. The method is based on monitoring the changes in the voltage of PV array and using it as an indicator of islanding. Thus, if the monitored values exceed a pre-determined threshold, occurrence of an islanding situation in the system will be indicated. The proposed algorithm is not relied on complex signal processing techniques, making it advantageous due to low computational burden for extraction of desired features. The performance of the method is assessed by simulating a typical system in MATLAB/Simulink, and the validity of it is verified.


MTM and other time measurement systems have been applied to human operators for many years. Now it is the time for robots to come under similar scrutiny. RTM uses different analysis methods to give predictions of cycle times within −2% to +3% for optimising selection and operating methods of robots.


The object of this paper is to give a unified and complete treatment of these related cases of lacunary interpolation whose special cases can be found scattered in the literature. We consider only the case when the nodes are the zeros of?n(x) whose derivative is ?n(n?1)Pn?1(x), the Legendre polynomial of degreen?1. We find the fundamental polynomials and give the convergence results.


Study Objectives: To look at the transition to becoming a father and the impact on other roles. Methods: A focused ethnography was undertaken for which a semi‐structured interview protocol was prepared based on the Occupational Performance History Interview (OPHI‐II) and issues highlighted in the literature. In‐depth interviews were conducted with a convenience sample of 4 Australian men and their partners who had all become first time parents during the previous year. Interviews were audio taped, transcribed, categorized, unitized, and examined for emerging themes. Triangulation included member checking and review by an independent researcher. Results: Although some of the themes that emerged were consistent with many of the findings in the literature there were some distinct differences: these men's occupational roles did change substantially after the birth of their first child and the importance of their working role also shifted. The themes that emerged included: becoming a father, role re‐negotiation, worker role, domestic roles, leisure role, loss of sleep, couple time, adopting the father role and facilitators and barriers to adopting their new occupational role 'father'. Limitations: This is an exploratory study with a small sample of convenience. All of the participants were parents of girls and of Anglo European descent. No longitudinal data was collected.


Let $R$ be a ring, a mapping $F:R\rightarrow R$ together with a mapping $d:R\rightarrow R$ is called a multiplicative (generalized)-reverse derivation if $F(xy)=F(y)x+yd(x)$ for all $x,y\in R$. The aim of this note is to investigate the commutativity of prime rings admitting multiplicative (generalized)-reverse derivations. Precisely, it is proved that for some nonzero element $a$ in $R$ the conditions: $a(F(xy)\pm xy)=0$, $a(F(x)F(y)\pm xy)=0$, $a(F(xy)\pm F(y)F(x))=0$, $a(F(x)F(y)\pm yx)=0$, $a(F(xy)\pm yx)=0$ are sufficient for the commutativity of $R$. Moreover, we describe the possible forms of generalized reverse derivations of prime rings.

Emission of metals by municipal solid waste incinerators (MSWIs) is one issue of great concern. In this study, the temporal variation in the levels of arsenic, cadmium, chromium, mercury, manganese, nickel, lead and vanadium in soil and vegetation samples collected near an MSW incinerator (Tarragona, Catalonia, Spain) was determined. In June 1997, 24 soil and 24 herbage samples were collected at the same sampling points in which samples had been taken in 1994. The present metal concentrations are generally within the ranges previously reported for soils and vegetation in the vicinity of MSWIs. Most metal levels remained unchanged or even decreased slightly between 1994 and 1997. According to the current results, the potential health impact of metals on the population living in the area under influence of the plant seems to be small.


The multiple point geostatistics can not reproduce the continuous shape of the channel due to the limitation of the algorithm with random draw of the simulated value. A new method is proposed which integrates the random walk process with multiple point geostatistics. First the random walk process produces the channel main streamline, then the draw of simulated value in multiple point geostatistics is conducted by the streamline. The method solves the continuities problem in channel. The real model is constructed with both the new method and only the multiple point geostatistics and the results show the new method can reproduce the continuous sinuous channel. A cross-validation is implemented and the result is also well, which proves the new method is robust and can be put into real reservoir modeling.


Tests have been carried out on a wing of symmetrical double wedge or rhombus section, 10% thickness, for aspect ratios 1∙5, 1∙25, 1∙0 and 0∙75 at Mach numbers 1∙3, 1∙5 and 2∙3. The wing was attached to the tunnel wall, and the results include the effect of the boundary layer on this wall. Lift, wave drag and normal force coefficients and the co-ordinates of the centre of pressure are given. A comparison with theory shows as good an agreement as can be expected. The experiments were made in the 11 in. square supersonic wind tunnel of the Engineering Division, N. P. L.


It is noted that, to create an effective new rail system in the US, passenger and freight services would be needed, both of them integrated and standardized in a national plan. It is suggested that it is absurd to pose the future of railroads as a complete dichotomy between superspeed passenger lines on one hand and slow freights meandering over decrepit trackage on the other hand. One would hope that the latter category would steadily shrink, but a unified system means that long-distance passenger service, commuter lines including airport access, and freight would move at optimal speeds and provide maximum convenience for their users. This objective-an integrated system, electrified for maximum energy saving and security-defines the details of what should be national policy as well as the tasks that US engineers must face in tackling the job. It is concluded that, if a new system is to fulfil its purposes, engineers will have to become part of an industrial rescue operation that has few parallels. >

There are several factors affecting physical and mechanical properties of the woven polyester fabrics, from these factors different weave constructions. The goal of this research is to study the effect of using different polyester fabric constructions on dyeing process via microwave irradiation. The resulted change in dye absorption, dyeing time and dyeing temperature were investigated. The fabric characteristics; namely tensile strength, elongation, and color fastness properties were also studied. The percentage dye exhaustion, dye fixation ratio and total dye fixation were evaluated. Dyeing rate constant, half dyeing time, activation energy and dye affinity of the different polyester fabric structures were calculated. The results this investigation proved that use of microwave irradiation brings about improvement in the quality of dyed fabric uniformity and color fastness properties. The woven polyester fabrics dyed with disperse dye and subjected to microwave irradiation for 50 min. at 100°C at different dye concentration increased dye concentration, and consequently enhanced the color strength for all the dyed samples. Fabric cover factor has significant effect on fabric strength as compared with other dependent variables.
