The nonlinear fractional relativistic Schr\"odinger equation: existence, decay and concentration results

In this paper we investigate the existence, decay and concentration behavior of solutions for the following class of fractional relativistic Schrodinger equations: \begin{equation*} \left\{ \begin{array}{ll} (-\Delta+m^{2})^{s}u + V(\varepsilon x) u= f(u) &\mbox{ in } \mathbb{R}^{N}, \\ u\in H^{s}(\mathbb{R}^{N}), \quad u>0 &\mbox{ in } \mathbb{R}^{N}, \end{array} \right. \end{equation*} where $\varepsilon>0$ is a small parameter, $s\in (0, 1)$, $m>0$, $N> 2s$, $(-\Delta+m^{2})^{s}$ is the fractional relativistic Schrodinger operator, $V:\mathbb{R}^{N}\rightarrow \mathbb{R}$ is a continuous potential satisfying a local condition, and $f:\mathbb{R}\rightarrow \mathbb{R}$ is a continuous subcritical nonlinearity. The approach is based on a variant of the extension method and applying appropriate variational techniques.
Developing a Personality Model for Speech-based Conversational Agents Using the Psycholexical Approach

We present the first systematic analysis of personality dimensions developed specifically to describe the personality of speech-based conversational agents. Following the psycholexical approach from psychology, we first report on a new multi-method approach to collect potentially descriptive adjectives from 1) a free description task in an online survey (228 unique descriptors), 2) an interaction task in the lab (176 unique descriptors), and 3) a text analysis of 30,000 online reviews of conversational agents (Alexa, Google Assistant, Cortana) (383 unique descriptors). We aggregate the results into a set of 349 adjectives, which are then rated by 744 people in an online survey. A factor analysis reveals that the commonly used Big Five model for human personality does not adequately describe agent personality. As an initial step to developing a personality model, we propose alternative dimensions and discuss implications for the design of agent personalities, personality-aware personalisation, and future research.
Determination of Ethyl Glucuronide in Human Hair Samples: Decontamination vs Extraction.

Decontamination of samples prior to analysis is common practice and recommended for EtG hair testing. The aim of this study was to evaluate the applied decontamination procedure during routine hair EtG analysis by monitoring of EtG concentrations in the washing solutions on a representative cohort of individual hair samples. Hair samples from 150 individuals were tested for hair EtG by a validated routine procedure (liquid chromatography/tandem mass spectrometry). A four-step decontamination procedure (ethanol, water, acetone, dichloromethane) was applied to all samples prior to analysis. Hair samples from 20 individuals were analyzed along with the complete set of individual washing solutions. Hair samples from additional 130 individuals were analyzed along with the corresponding aqueous wash fraction only. No EtG was detected in washing solutions from hair samples, which were tested negative for EtG (n=42). EtG positive hair samples (n=108) were found to liberate different amounts of EtG during decontamination: Whereas no or low portions of EtG (<10 % of extracted hair EtG) were found in the corresponding washing solutions by the majority (n=91) of individual samples, there was a minority of samples (n=6) with more than half of the extracted hair EtG present in the decontamination solvent. No correlation of the decontaminated amount of EtG and the extracted hair EtG was observed. Further experimental studies are necessary to investigate if the observed easily removable fraction of EtG is associated with external contamination and if analysis of wash solutions could be helpful to identify external contamination in EtG hair testing.
Attention and Housing Search: Evidence from Online Listings

We study fluctuations in households’ attention to the housing market and their effects on home sales. Exploiting a unique dataset that tracks user activity on a major property website, we show that buyers’ attention positively responds to price growth in their postcode of residence. The increase in attention does not translate into higher effort allocated to inspecting individual listings, but in more extensive searches, covering a broader range of locations and property characteristics. These effects are mainly driven by homeowners, young households and residents of lower price postcodes in particular, consistent with higher price growth affecting users behavior through wealth effects or the easing of collateral constraints. Our results are stronger when postcode price growth is instrumented using a measure of local supply-elasticity. More extensive searches reduce segmentation on the demand side of the market, leading to higher prices and lower time on the market for homes listed for sale. This implies that fluctuations in households’ attention have procyclical effects on house price growth and generate spillovers within metropolitan areas.
How Fit Are the Person and Organization at UIN Jakarta?

This study aims to get a picture of the compatibility between people and organizations (Person Organization Fit / POF) in the scope of UIN Jakarta. POF is conformity between people and the organization, through values, culture, and satisfaction. The quantitative method by analysing the description and different tests of 222 respondents obtained by a non-probability sampling of lecturers, employees and UIN students. Different test for UIN members shows that there is a compatibility between the members' values and the values owned by UIN as an organization, besides that there are no differences in values held by UIN group members from all elements.
Wild Bee Conservation within Urban Gardens and Nurseries: Effects of Local and Landscape Management

Across urban environments, vegetated habitats provide refuge for biodiversity. Gardens (designed for food crop production) and nurseries (designed for ornamental plant production) are both urban agricultural habitats characterized by high plant species richness but may vary in their ability to support wild pollinators, particularly bees. In gardens, pollinators are valued for crop production. In nurseries, ornamental plants rarely require pollination; thus, the potential of nurseries to support pollinators has not been examined. We asked how these habitats vary in their ability to support wild bees, and what habitat features relate to this variability. In 19 gardens and 11 nurseries in California, USA, we compared how local habitat and landscape features affected wild bee species abundance and richness. To assess local features, we estimated floral richness and measured ground cover as proxies for food and nesting resources, respectively. To assess landscape features, we measured impervious land cover surrounding each site. Our analyses showed that differences in floral richness, local habitat size, and the amount of urban land cover impacted garden wild bee species richness. In nurseries, floral richness and the proportion of native plant species impacted wild bee abundance and richness. We suggest management guidelines for supporting wild pollinators in both habitats.
Association of Epoxide Hydrolase 2 Gene Arg287Gln with the Risk for Primary Hypertension in Chinese

Background Epoxide hydrolase 2 (EPHX2) gene coding for soluble epoxide hydrolase is a potential candidate in the pathogenesis of hypertension. Objectives We aimed to assess the association of a missense mutation, R287Q, in EPHX2) gene coding for soluble epoxide hydrolase is a potential candidate in the pathogenesis of hypertension. Methods This study involved 782 patients with primary hypertension and 458 healthy controls. Genotyping was done using TaqMan technique. Activity of soluble epoxide hydrolase fusion proteins was evaluated by the conversion of 11,12-EET to corresponding 11,12-DHET using ELISA kit. Results After taking carriers of R287Q variant GG genotype as a reference, those with GA genotype had a significantly reduced risk of hypertension (adjusted odds ratio: 0.72, 95% confidence interval: 0.56 to 0.93, P = 0.013). Five significant risk factors were identified, including age, body mass index, total cholesterol, homocysteine, and R287Q variant. These five risk factors for hypertension were represented in a nomogram, with a descent prediction accuracy (C-index: 0.833, P = 0.013). Five significant risk factors were identified, including age, body mass index, total cholesterol, homocysteine, and R287Q variant. These five risk factors for hypertension were represented in a nomogram, with a descent prediction accuracy (C-index: 0.833, Conclusions We provide evidence that R287Q mutation in EPHX2 gene was associated with reduced risk of primary hypertension and low activity of soluble epoxide hydrolase.EPHX2) gene coding for soluble epoxide hydrolase is a potential candidate in the pathogenesis of hypertension.
Live to Fight Another Day? The Mortality Anxiety of Organized Interests: Government Patronage in Times of Austerity

Quite some recent research on advocacy demonstrates a link between organizational maintenance and the political activities of organized interests. This paper focuses on organizational maintenance and seeks to explain varying levels of mortality anxiety. Based on a large survey among Belgian interest groups, we show that strong government patronage in times of austerity as well as inter-organizational competition has a substantial impact on mortality anxiety. Basic organizational features – such as organizational age or membership – seem to be much less important than the resource dependencies with government agencies. Furthermore, our analysis demonstrates that neo-corporatist systems may exemplify much higher levels of competition and organizational volatility than is often assumed.

ECHOCARDIOGRAM SEGMENTATION USING ACTIVE CONTOURS WITH PREPROCESSING STEP SEGMENTACIJA EHOKARDIOGRAMA

Segmentation of echocardiograms is difficult task since speckle noise embedded in ultrasound images. Standard techniques for image segmentation, such as thresholding, region growing or watershed method, give poor results in heart chambers segmentation. Active contours “without edges” proved to be robust to noise and applicable for ultrasound images segmentation. In this paper we use this model together with preprocessing step, Kuwahara filtering, which enables low-pass filtering in homogeneous regions while preserving edges (i.e. high frequency components) in image.
ON DATA BALANCING FOR EFFICIENT DEEP LEARNING WITH PATHOLOGY IMAGES

We investigated a data balancing technique for effective deep learning with pathology images that often contain severely imbalanced data. Our proposed data balancing scheme with ResNet-101 yielded substantially improved performance for detecting cancer metastasis area, especially small area. Then, our random forest classifier yielded the final classification results of cancer staging for the submission of Camelyon’17
Fractional K-BKZ Numerical Model of the Start-Up Flow for a Viscoelastic Shock Absorber

This paper has proposed a fractional K-BKZ numerical model by adopting the framework of the classical K-BKZ model and the relaxation modulus of the fractional Maxwell model with quasiproperties to study the start-up flow of a viscoelastic shock absorber. The start-up flows in both the orifice and the gap of a shock absorber were simplified to unidirectional accelerated flows in a pipe and between two parallel plates where one plate is accelerating and the other is at rest. The fractional K-BKZ numerical model was then developed using the finite difference method with real-world initial and boundary conditions. Numerical simulation was then performed, and the results were validated through laboratory testing, based on a comparison of the maximum fluid level and the contact angle. The proposed fractional K-BKZ numerical model successfully simulated the characteristics of the viscoelastic material passing through the orifice or the gap of a shock absorber, as demonstrated by accurately capturing the change of the shape of the flow. This fractional K-BKZ numerical model provided better accuracy for the fluid’s viscoelasticity and can be used for shock absorber design.
Topical Tacrolimus for the Treatment of Oral Lichen Planus

Lichen planus is a chronic inflammatory mucocutaneous disease that can have both cutaneous and oral involvement. Clinical presentations of oral lichen planus are varied and the erosive form can be the most symptomatic and difficult to treat. New research in cytokine biology may begin to help explain the pathogenesis and chronicity of oral lichen planus. Conventional treatment for oral lichen planus includes topical and intralesional corticosteroids. Tacrolimus, a calcineurin-inhibitor, has been shown to be effective in treating lesions of erosive oral lichen planus that are recalcitrant to topical steroid therapy. We would like to present a case in which a patient with severe erosions of the tongue, due to oral lichen planus, was effectively treated with topical tacrolimus following unsuccessful topical and intralesional steroid therapy.
Feedback System in Healthcare: The Why, What and How

Background: A lively, dynamic and interactive feedback system that can connect all the stakeholders and engage them in a sustainable loop of seamless information flow is quintessential for any organization with significant public interface. It is important to balance the asymmetry in the patient doctor relationship and empower the patients. Methodology: In this regard, process mapping of existing system was done. Ethnographic methods were used with triangulation of data for validity. Three key bottlenecks were identified; the system to collect feedback, the feedback form itself and the overall mindset about the feedback system. A de novo, systematic approach akin to the PDSA (Plan-Do-Study-Act) steps in quality improvement was adopted to create a new feedback system and its continuous incremental improvements thereon. Results: Short, attractive form with interactive emoticons graded over a likert scale was created and made accessible through standalone kiosks across the institute. Key attention to ease of access, minimizing the number of clicks, removing human interface and providing SMS/E-mail acknowledgement to feedbacks have all contributed to sustainability of the new system with consistently high turn-out/participation. Conclusion: Designing a customized, hospital specific feedback system rooted more in the experiences on ground is more sustainable and reliable rather than standardized surveys. The same has been reiterated in literature. They can also be used to assess the impact of new interventions. Robust feedback systems can be envisioned as part of accreditation and continuous quality improvement.
Response to Reviewers Examining Committed Action in Chronic Pain: Further Validation and Clinical Utility of the Committed Action Questionnaire Resubmitted to The Journal of Pain

Psychosocial treatments for chronic pain conditions, such as Acceptance and Commitment Therapy (ACT), have highlighted minimizing pain avoidance behaviors and increasing engagement in valued activities as key treatment targets. In terms of salient processes within ACT, committed action is considered essential to the pursuit of a meaningful life, as it entails a flexible persistence over time in living consistently with one's values. To date, however, only one study has examined the association between measures of committed action and important aspects of pain-related functioning. The purpose of the present study was to analyze the reliability of the Committed Action Questionnaire (CAQ) in a sample of 149 chronic pain patients, perform a confirmatory analysis of its factor structure, and examine how CAQ scores uniquely account for variance in functioning. Confirmatory factor analyses provided support for a two-factor model, and regression analyses, which examined the cross-sectional direct effects of the two subscales on health-related functioning, indicated that the CAQ accounted for significant variance in functioning after controlling for relevant covariates. Overall, these findings provide further support for the CAQ as a measure of adaptive functioning in those with longstanding pain. Highlights:  Examined the utility of the committed action questionnaire in chronic pain patients  149 pain patients were included in the analyses  Results of the analyses showed support for the two-factor model  Committed action scores were significantly associated with psychosocial functioning Highlights
DWARF HAKE OFF THE COAST OF BAJA CALIFORNIA, MEXICO

Dwarf hake found in southern California is compared to Merluccius productus, the common hake found along the western coast of the’united States, through morphometric measurements, meristic counts, and the electrophoresis of tissue proteins from the eye lens, vitreous humor, and muscle myogens. Dwarf hake differs significantly from M. productus to suggest it may be a separate species and does not interbreed with either M. productus or the rarer M. angustimanus . I NTRODU CTI 0 N This study was initiated to investigate the possibility of more than one stock of hake living off the coast of California and Baja California, Mexico. Merluccius productus is the common hake which spawns from off northern California to the tip of Baja California (Ahlstrom and Counts, 1955; Kramer and Smith, 1970). Ginsburg (1954) indicated the range of M. angusfimanusextended northward along the west coast of Baja California to Del Mar, California, but Ahlstrom and Counts (1955) found no evidence of eggs or larvae of any species other than M. productus. MacGregor (1971) collected a number of small hake off southern Baja California in January 1970, for fecundity studies. The smallest maturing male he found was 119 mm standard length (SL) and the smallest maturing female was 125 mm SL. All males 129 mm SL and longer and all females 140 mm SL and longer were sexually mature. The size at which these hake were mature was less than half that reported by Best (1963) who found only one mature fish shorter than 400 mm total length (TL) . This fish was a female 380 mm TL (about 336 mm SL) with small ovaries filled with maturing eggs. We obtained 51 frozen specimens from the same sample taken by MacGregor on January 11, 1970, at 26“07’ N, 11397’ W. After thawing, all the fish in this sample had a rather red skin color. The red color is not consistent however, and has not been observed in subsequent samples. Perhaps the red color was caused by abrasion during capture as the fish had virtually no scales left because they had to be picked out of over 3,000 lbs (1,360 kg) of pelagic red crabs, Pieuroncodespimpes, that were caught in the same trawl. The red color faded to grey-brown when the fish were preserved in formalin. The age of 56 hake from this and subsequent samples was determined from an examination of otoliths. The mean length at age I was similar to the mean length Best (1963) found for M. productus, but age groups I1 through V were remarkably smaller (Table 1, Figure 1). Of the 393 individual fish which we have identified and measured, the largest was only 305 mm SL and 97% of them were 250 mm SL or iess.
An Empirical Investigation of Real Exchange Rate Responses to Foreign Currency Inflows: Revisiting the Dutch Disease Phenomenon in South Asia

Inflows of foreign currencies into the developing economies, in particular, have been associated with the Dutch disease phenomenon whereby a surge in such inflows is believed to stimulate real appreciation of the real exchange rate. As a result, there could be deindustrialization impacts on the recipient economies following a growth in the non-tradable sector at the expense of the tradable sector's contraction. This paper empirically investigates the dynamics of real exchange rate responses to official development assistance, foreign direct investments and international remittances flowing into the four emerging South Asian economies Bangladesh, India, Pakistan, and Sri Lanka. The results from the extensive econometric analyses show that a 1% rise in the total volume of official development assistance and remittances received appreciates the real exchange rate by 0.18% and 0.23% respectively. In contrast, a 1% rise in FDI inflows was found to trigger a 0.19% depreciation of the real exchange rate. Furthermore, the Dumitrescu and Hurlin (2012) test results reveal unidirectional long run causalities running from official development assistances and FDI inflow to real exchange rate while certifying a bidirectional causal association between inward international remittances and the real exchange rate.
Study on Corrosion Characteristics of Concrete-Filled CFRP-Steel Tube Piles under Hygrothermal Environment

The corrosion damage of pile foundations caused by a hygrothermal environment is a significant factor that influences the service life of high-pile wharf structures. The concrete-filled CFRP-steel tube (CFRP-CFST) pile is a composite structure composed of external Carbon Fiber-Reinforced Polymer (CFRP) sheets and inner concrete-filled steel tubes. It has a high-bearing capacity and excellent corrosion resistance and is an ideal structure for pile foundations in aggressive environments. In this paper, twelve CFRP-CFST pile specimens with diameters of 114 mm and heights of 1200 mm and another forty-two CFRP-steel plate specimens with CFRP widths of 30–50 mm were built. A high hot and humid environment simulation system was designed to conduct corrosion experiments with these specimens. At different theoretical corrosion degrees, the half-cell potential, corrosion products, corrosion expansion, and adhesive property were investigated. The test results showed an obvious increase in the mechanical properties and corrosion resistance when the concrete-filled steel tube was externally bonded to CFRP sheets. The experimental results show that the CFRP-CFST pile is an effective way to protect piles from corrosion and can be widely used for high-pile wharfs in aggressive environments.
SUSTAINABLE AMMONIA: A KEY TECHNOLOGICAL CHALLENGE FOR ASIA

Ammonia is one of the most important industrial chemicals in the world. The availability of an inexpensive and environmentally sustainable supply of ammonia which is an important ingredient in fertilizer is important for the security of the world food supply. Asia is one of the biggest consumers of ammonia. The Haber-Bosch process makes ammonia widely available now but it requires high temperatures and pressures, consumes large quantities of fossil fuels and releases large amounts of greenhouse gases. Sustainable ammonia is also important because it may make biomass-based alternatives to fossil fuels more practical. Possible alternatives under development are those that mimic the enzymatic processes that occur at mild conditions in nature and those that seek to obtain ammonia-based compounds from large-scale culture of microalgae and cyanobacteria. Many of the alternatives are still in the very early stages of development and researchers are urged to enter the field.
GHB, and flunitrazepam among American youths

Background: The magnitude and the characteristics of the use of methamphetamine, MDMA (Ecstasy), LSD (d-lysergic acid diethylamide), ketamine, GHB (gamma-hydroxybutyrate), and flunitrazepam (Rohypnol) were examined in a probability sample of the U.S. civilian population that included multiethnic urban, suburban, and rural youths aged 16–23 (N = 19,084).
