Two-photon blockade and photon-induced tunneling generated by squeezing

Inspired by the recent experiment of Hamsen \emph{et al.} [Phys. Rev. Lett. 118, 133604 (2017)], which demonstrated two-photon blockade in a driven nonlinear system (composed of a harmonic cavity with a driven atom), we show that two-photon blockade and other nonstandard types of photon-blockade and photon-induced tunneling can be generated in a driven harmonic cavity without an atom or any other kind of nonlinearity, but instead coupled to a nonlinear (i.e., squeezed) reservoir. We also simulate these single- and two-photon effects with squeezed coherent states and displaced squeezed thermal states.
Using Geospatial Techniques in the Selection of Potential Ecotourism Sites in Menz-geramidir District, Ethiopia

Ecotourism is expressed as when tourists are attracted to a given geographic area (i.e. space) which has its own available natural, environmental, and socioeconomic resources by considering environmental sustainability, local benefit, and promotion. Space is an elementary part of ecotourism activities. Hence, the aim of this study is to identify potential ecotourism sites in Menz-geramidir district mainly by considering the natural features. Using weighting of each factor, three criteria and five-factor maps are identified, namely: landscape (land use land cover map), topography (elevation and slope map) and accessibility (road and river map). Those identified factor maps first ranked based on expert opinion, and then the weight of influence ofeach factor was computed by pair-wise comparison technique which is one of AHP method. The image classification was carried out in ERDAS imagine software using supervised image classification method. The image classification accuracy assessment indicates that the overall accuracy is 84% and the overall Kappa coefficient is 0.80. The final ecotourism potential sites model map was created based on the linear combination of factors with their respective weights in ArcGIS overlay extension and presented using FAO`s suitability scheme into four classes. The result showed that11% is highly suitable and lies to the eastern part of the study area. Generally,major suitable and moderately suitable area accounts for 75.6 % and marginally suitable area for 13.5 % and the not suitable area is 0.06 %. Therefore, this study shows that the district has high ecotourism potential which can contribute to the livelihood of the community through sustainable environmental development and protection.

Irreducible nonsurjective endomorphisms of Fn are hyperbolic

Previously, Reynolds showed that any irreducible nonsurjective endomorphism can be represented by an irreducible immersion on a finite graph. We give a new proof of this and also show a partial converse holds when the immersion has connected Whitehead graphs with no cut vertices. The next result is a characterization of finitely generated subgroups of the free group that are invariant under an irreducible nonsurjective endomorphism. Consequently, irreducible nonsurjective endomorphisms are fully irreducible. The characterization and Reynolds' theorem imply that the mapping torus of an irreducible nonsurjective endomorphism is word‐hyperbolic.
Session-based Complementary Fashion Recommendations

In modern fashion e-commerce platforms, where customers can browse thousands to millions of products, recommender systems are useful tools to navigate and narrow down the vast assortment. In this scenario, complementary recommendations serve the user need to find items that can be worn together. In this paper, we present a personalized, session-based complementary item recommendation algorithm, ZSF-c, tailored for the fashion usecase. We propose a sampling strategy adopted to build the training set, which is useful when existing user interaction data cannot be directly used due to poor quality or availability. Our proposed approach shows significant improvements in terms of accuracy compared to the collaborative filtering approach, serving complementary item recommendations to our customers at the time of the experiments CF-c. The results show an offline relative uplift of +8.2% in Orders Recall@5, as well as a significant +3.24% increase in the number of purchased products measured in an online A/B test carried out in a fashion e-commerce platform with 28 million active customers.
Getz Ice Shelf melt enhanced by freshwater discharge from beneath the West Antarctic Ice Sheet

Abstract. Antarctica's Getz Ice Shelf has been rapidly thinning in recent years, producing more meltwater than any other ice shelf in the world. The influx of fresh water is known to substantially influence ocean circulation and biological productivity, but relatively little is known about the factors controlling basal melt rate or how basal melt is spatially distributed beneath the ice shelf. Also unknown is the relative importance of subglacial discharge from the grounded ice sheet in contributing to the export of fresh water from the ice shelf cavity. Here we compare the observed spatial distribution of basal melt rate to a new sub-ice-shelf bathymetry map inferred from airborne gravity surveys and to locations of subglacial discharge from the grounded ice sheet. We find that melt rates are high where bathymetric troughs provide a pathway for warm Circumpolar Deep Water to enter the ice shelf cavity and that melting is enhanced where subglacial discharge fresh water flows across the grounding line. This is the first study to address the relative importance of meltwater production of the Getz Ice Shelf from both ocean and subglacial sources.
LİDERLİK ETME MOTİVASYONU VE DUYGUSAL ZEKÂ ARASINDAKİ İLİŞKİDE ÖZ YETERLİLİĞİN ROLÜ ÜZERİNE BİR ARAŞTIRMA

Today, with the influence of globalization, leadership is regarded as one of the most important factors determining the success of organizations. Although leadership is one of the many theoretical and empirical studies on social sciences and organizational behavior literature, individuals' wish to lead has not been fully explained in those theoretical and empirical studies. A pioneering work on the development of an empirical model that explains the leadership trends of individuals through the concept of motivation to complete this gap in leadership has been initiated by Chan ve Drasgow (2001) that based the motivation of leadership on three subdimensions as affective-identity, social normative and non-calculative motivation to lead. In this study, we examine the mediating effect (indirect) of self-efficacy on the relationship between motivation to lead and emotional intelligence. Within the scope of the research, a model based on hypotheses was established to determine the relationships between variables. The results of the study were obtained using Chan and Drasgow (2001) Motivation to Lead Scale, Wong and Law (2002) Emotional Intelligence Scale, and Jerusalem and Schwaeter (1981) General Self-Efficacy Scale. The obtained data were analyzed by correlation, regression and structural equation modeling (SEM) test. According to research findings, indirect effects were observed as a result of the mediation test, and these indirect effects were significant. However, it was found that emotional intelligence did not significantly affect the motivation to lead when the regression values were examined. This is why emotional intelligence has no role in mediating selfefficacy in its impact on motivation to lead.
EVALUATION OF BEHAVIOR OF WASTE DISPOSAL SITES IN KARACHI, PAKISTAN AND EFFECTS OF ENHANCED LEACHING ON THEIR EMISSION POTENTIAL

This study aims to assess the efficiency of enhanced leaching on biodegradation of residual waste and gas emissions from waste disposal sites. The investigation simulated the waste disposal conditions in the landfill sites of Karachi, Pakistan in terms of waste composition, moisture content, and climatic conditions. For this purpose, a lysimetric analysis method was applied. Landfill sites in Karachi have typically no cover and the waste degrades in relatively dry conditions due to the lower moisture content of the waste as well as due to the low annual rainfall. Decomposition of organic waste with low moisture content and limited water introduction is causing prolonged emissions in the form of gas and leachate due to the slow biodegradation process. This paper focuses on the comparison of gaseous emissions from waste disposal sites in two different circumstances by applying two different experimental approaches. In the first approach, the actual dry conditions were simulated by means of limited water addition and without leachate recirculation. In the second approach, enhanced leaching conditions were provided with process water addition and leachate recirculation. The results from 100 days of experimental operation revealed that an enhanced leaching is able to increase gas formation in comparatively short periods and prolongs gaseous emissions from waste disposal sites can be controlled. This lab scale study can provide baseline data for further research and planning to transform waste dumpsites to sanitary landfills in the region.
A unified elasto-plastic constitutive model for sandy and clayey soils accounting for at-rest condition

ABSTRACT Taking advantages of some existing two-surface soil constitutive models in a critical state framework, a unified two-surface constitutive model was developed for rigorous simulation of elasto-plastic deformation of different soils such as loose and dense sands, normally and over-consolidated clayey soils subjected to any type of monotonic loadings. Employing the dilatancy parameter, the strain-softening and stress-dilatancy were described using non-associated flow rule to generalise the application of the model to different soils under various stress states. The applicability of the proposed model was validated comparing the numerical simulations with the existing experimental data for variety of soils subjected to different phases of monotonic loadings. The model was found to be capable of simulating drained and undrained behaviour of clayey and sandy soils under triaxial stress conditions as accurate as the constant stress-ratio loading state. The results also demonstrated the ability of the model to determine the at-rest earth pressure coefficient (K0 ) for variety of soils suitable to be applied to the geotechnical problems affected by this parameter such as piles groups and retaining earth structures. While the formulation of hardening parameter in the integration scheme is based on volumetric and deviatoric plastic strains, the simulation of dilatancy response especially in dense sands showed an excellent agreement with the experimental data.
From the reference human genome to human pangenome: Premise, promise and challenge

The Reference Human Genome remains the single most important resource for mapping genetic variations and assessing their impact. However, it is monophasic, incomplete and not representative of the variation that exists in the population. Given the extent of ethno-geographic diversity and the consequent diversity in clinical manifestations of these variations, population specific references were developed overtime. The dramatically plummeting cost of sequencing whole genomes and the advent of third generation long range sequencers allowing accurate, error free, telomere-to-telomere assemblies of human genomes present us with a unique and unprecedented opportunity to develop a more composite standard reference consisting of a collection of multiple genomes that capture the maximal variation existing in the population, with the deepest annotation possible, enabling a realistic, reliable and actionable estimation of clinical significance of specific variations. The Human Pangenome Project thus is a logical next step promising a more accurate and global representation of genomic variations. The pangenome effort must be reciprocally complemented with precise variant discovery tools and exhaustive annotation to ensure unambiguous clinical assessment of the variant in ethno-geographical context. Here we discuss a broad roadmap, the challenges and way forward in developing a universal pangenome reference including data visualization techniques and integration of prior knowledge base in the new graph based architecture and tools to submit, compare, query, annotate and retrieve relevant information from the pangenomes. The biggest challenge, however, will be the ethical, legal and social implications and the training of human resource to the new reference paradigm.
Correspondence between waist-to-height ratio and body mass index in juniors

Despite the increase in body mass through childhood and adolescence is countered by the increase in height in the Body Mass Index (BMI), this measure is inadequate for judging the degree of excess weight among the young. Unlike using clearly defined cut points, same for any stage of adulthood, it is required to consult BMI-for-age charts, which can be a demanding exercise when data analysis is involved. The waist circumference to height ratio (WCHR) was hypothesised to be invariant to age change, and this is generally supported by the epidemiological evidence. This paper analyses a sample of NHANES data to find a connection between BMI, WCHR and Age. A strong linearity between the anthropometric measures is demonstrated, thus enabling estimation of WCHR for a given BMI and Age. The pattern of change of this parameter at BMI levels that indicate the transition to overweight state or obesity thus becomes unravelled. The results strongly support the feasibility of a universal WCHR threshold for the overweight state past early childhood and through adolescence, and the estimated one is similar to the WCHR levels found elsewhere in the literature.
Multiple meanings of behavior: Construing actions in terms of competence or morality.

Multiplicity of behavior features gives rise to its different interpretations (in addition to behavior vagueness and ambiguity typically studied in social cognition research). Particularly, identical actions are construable both in moral and competence-related categories due to distinct behavioral features underlying each of these interpretations. It was hypothesized that the two construals are alternatively used by the perceiver. Because of perspective-dependent differences in accessibility and applicability of competence and moral categories, it was hypothesized that actors interpret their own behavior in competence terms, whereas observers interpret it in moral categories, and that within the actor perspective, competence construal is used to a higher degree by male than female perceivers, but the opposite is true for moral construal

Thrombin generation assays to personalize treatment in bleeding and thrombotic diseases

Treatment of bleeding and thrombotic disorders is highly standardized and based on evidence-based medicine guidelines. These evidence-based treatment schemes are well accepted but may lead to either insufficient treatment or over-dosing, because the individuals’ hemostatic properties are not taken into account. This can potentially introduce bleeding or thrombotic complications in individual patients. With the incorporation of pharmacokinetic (PK) and pharmacodynamic (PK-PD) parameters, based on global assays such as thrombin generation assays (TGAs), a more personalized approach can be applied to treat either bleeding or thrombotic disorders. In this review, we will discuss the recent literature about the technical aspects of TGAs and the relation to diagnosis and management of bleeding and thrombotic disorders. In patients with bleeding disorders, such as hemophilia A or factor VII deficiency, TGAs can be used to identify patients with a more severe bleeding phenotype and also in the management with non-replacement therapy and/or bypassing therapy. These assays have also a role in patients with venous thrombo-embolism, but the usage of TGAs in patients with arterial thrombosis is less clear. However, there is a potential role for TGAs in the monitoring of (long-term) antithrombotic therapy, for example with the use of direct oral anticoagulants. Finally this review will discuss controversies, limitations and knowledge gaps in relation to the introduction of TGAs to personalize medicine in daily medical practice.
Raw Water Storage as a Simple Means for Controlling Membrane Fouling Caused by Inorganic Foulants in River Water in a Tropical Region

Natural waters in tropical countries are turbid and rich in inorganic substances such as iron and manganese. Hence, membrane fouling by these inorganic substances is the most serious problem in membrane filtration processes for potable water production. This study aimed to assess raw water storage as a simple but effective means for controlling membrane fouling in the filtration of river water in a tropical country. Raw water taken from the Ping River in Chiang Mai, Thailand, in different seasons, was either immediately filtered or stored in a tank for two days before filtration through a polyvinylidene difluoride (PVDF) membrane with a nominal pore size of 0.1 μm. The turbidity and particulate organic carbon (POC) in the raw water were reduced by storage, while dissolved manganese was oxidized during the storage period. Although the amounts of metallic substances retained on membranes were larger than those of silica and organic matter, their contribution to the fouling resistance was found to be less than silica and organic carbon. The fouling analysis using hydraulically irreversible fouling index (HIFI) was found to be not able to measure the effects of storage when the initial flux increased. Hence, the ratio of the hydraulically reversible fouling index (HRFI) to the total fouling index (TFI), i.e., HRFI/TFI, was proposed to elucidate the effects of raw water storage on membrane fouling, which was manifest during the early stage of membrane filtration operation.
QR Factorization for the CELL Processor

The QR factorization is one of the most important operations in dense linear algebra, offering a numerically stable method for solving linear systems of equations including overdetermined and underdetermined systems. Classic implementation of the QR factorization suffers from performance limitations due to the use of matrix-vector type operations in the phase of panel factorization. These limitations can be remedied by using the idea of updating of QR factorization, rendering an algorithm, which is much more scalable and much more suitable for implementation on a multi-core processor. It is demonstrated how the potential of the CELL processor can be utilized to the fullest by employing the new algorithmic approach and successfully exploiting the capabilities of the CELL processor in terms of Instruction Level Parallelism and Thread-Level Parallelism.
Non-Intrusive Health-Monitoring Devices

Technological advancements in medical and health-care areas have brought about the longevity of human beings. The World Health Organization recognizes that “the world population is rapidly ageing” and that it is necessary to “reinvent our assumptions of old age” to promote healthy living (WHO, n.d.). The subsequent increase in health-related expenses has imposed significant financial burdens on many governments and individuals. The US government has had to push for a reform in the country’s medical system in order for it to stay sustainable in the future. Monitoring well-being, early disease detection and preventive health-care are becoming increasingly important in reducing the high cost of treatment and recovery from illness. This can be alleviated through the realization of e-health, by computerizing the whole process and analyzing data on a continuous basis. There are many facets of e-health. In the large scale, it involves the complete workflow of acquiring, storing and retrieving medical records, controlling accessibility and access privileges to those records, and managing the security and privacy issues that arise, for instance, the Cardiovascular Health Informatics and Multi-modal E-record (CHIME) (Zhang, Poon, & MacPherson, 2009). Monitoring and analysis on the health condition could also be performed over the cloud, riding on recent advancement of efficient and high bandwidth communication infrastructure (Li, Guo, & Guo, 2014). It has been demonstrated that the continually acquired heart-beat rate and blood pressure time series could be very useful in monitoring patient progress and predicting patient survival rate via machine learning approaches (Lehman et al., 2015). In the context of health monitoring, a major focus is on the efficient acquisition of medical information for storage and analysis. Advances in health monitoring technologies have also blurred the distinction between health and disease to make it a continuum, with a paradigm shift towards prevention, prediction, personalized treatment and participatory medicine (Andreu-Perez, Leff, Ip, & Yang, 2015). In this chapter, the preventive stage of health problem, along the venue of effective health monitoring, is studied. Many contemporary health-monitoring technologies are more or less based on intrusive devices, which impose certain burdens on users and demand that they adapt to the presence of those devices. Even though this is rather accepted for a patient, this is not quite desirable for a normal person, since it will inevitably affect his/her daily life and work, especially when continual monitoring is in place. In this chapter, contemporary health-monitoring technologies are revisited, with an emphasis being paid Non-Intrusive Health-Monitoring Devices
