Relationship in Conservation Group Geometry

Pandres has developed a theory which extends the geometrical structure of a real four-dimensional space-time via a field of orthonormal tetrads with an enlarged covariance group. This new group, called the conservation group, contains the group of diffeomorphisms as a proper subgroup and we hypothesize that it is the foundational group for quantum geometry. Using the curvature vector, Cμ, we find a free-field Lagrangian density CμCμ √−g . When massive objects are present a source term is added to this Lagrangian density. Spherically symmetric solutions for both the free field and the field with sources have been derived. The field equations require nonzero stress-energy tensors in regions where no source is present and thus may bring in dark matter and dark energy in a natural way. A simple model for a galaxy is given which satisfies our field equations. This model includes flat rotation curves. In this paper we compare our results with recently reported results of McGaugh, Lelli and Schombert which exhibit a new law between the observed radial acceleration and the baryonic radial acceleration. We find a slightly different model which relates these accelerations. In conjunction with our model, the McGaugh, Lelli and Schombert relation imply a new critical baryonic acceleration. When applied to bulge-dominated galaxies, this critical baryonic acceleration may be used to predict the radial velocity curve value by using the radius of the bulge.
Human Connectomics Visualization: Techniques and Methodologies

Studies in understanding how brain regions are interconnected is recently becoming more and more popular. Thanks to the advances in non-invasive neuroimaging technologies, such as functional Magnetic Resonance Imaging (fMRI) and Diffusion Tensor Imaging (DTI), large dataset can also be collected from living subjects. Thus, the need of visual analytic tools able to deal with this data is becoming a priority for neuroscientists. This work aims at surveying the main visualization techniques and methodologies already present in the academic literature as well as the new trends are taking place in this ﬁeld. The main phenomena we are witnessing is a transition from stand-alone, local 2D visualization tools to more ﬂexible and cross-platforms web-based applications which exploit 3D rendering.
Current Saturation in Few-layer MoS2 FET

The discovery of graphene in 2004 has sparked great interest in 2-dimensional (2D) materials for their use in the next generation of electronic devices. [1] Although graphene exhibits some remarkable and really unique electrical properties that may help overcome some of the main limitations in analog electronics,[2][3] its lack of bandgap has limited its use for digital applications. On the other hand, molybdenum disulphide (MoS2), another two-dimensional material with a band gap of 1.8 eV in single layer and 1.2 eV in bulk, has recently been used in field effect transistors with excellent gate modulation and current pinch-off. [4][5][6] Monolayer MoS2 is composed of one layer of molybdenum atoms sandwiched between two layers of sulphur atoms for a total thickness of 0.65 Å. Mobility around 300 cm 2 /V.s and an on-off current ratio exceeding 10 7 have been experimentally demonstrated while a large gm (4.4 mS/μm) and excellent short channel behavior (drain induced barrier lowering ~10 mV/V and subthreshold swing ~60 mV/decade with gate length of 15nm) have been predicted. Its potential to reduce short channel effect in highly scaled devices thanks to its excellent electrostatic confinement, together with its high thermal stability, chemical inertness and mechanical properties makes MoS2 transistors excellent candidates for low power mixed-signal electronics. In this paper, we show MoS2 FETs with current saturation, for the first time. The saturation behaviour is extremely important for building both digital and analog circuits. This property is lacking in most graphene FETs due to its zero bandgap and is also not observed in the MoS2 FETs reported in the literature so far. Few-layer MoS2 flakes are first obtained from bulk crystals using adhesive-tape-based micromechanical exfoliation onto degenerately-doped Si substrates covered with 285nm thick SiO2. The sample was then annealed at 300C for 6 hours in forming gas (20 sccm H2 and 600 s ccm Ar) to flatten the flakes and remove the tape residues. The number of layers in the MoS2 flake is then confirmed by optical microscopy, Raman spectrum and Atomic Force Microscopy (AFM). The exfoliated MoS2 flakes we investigate always have 1 layer to 6 layers with thickness of 0.7 to 4nm. Figure 1(a) shows the optical micrograph of a typical few-layer MoS2 flake. The Raman spectrum (Inset of Figure 1 (a)) was measured at room temperature using a 532 nm laser. Two peaks at 384 and 405 cm -1 are attributed to the in-plane E 1 2g and out-of-plane A1g vibration of MoS2 respectively. [7] The AFM image (Figure 1(b)) demonstrates that the current sample has very clean and flat surface. This flake contains 5 layers of MoS2, with a total thickness of 3.5 nm, as shown in the step image in the inset of figure 1(b). The metal contacts are defined using electron beam (e-beam) lithography, followed by deposition of 3 nm titanium / 50 nm gold metal stacks using e-beam evaporation. Figure 1(c) shows an optical micrograph of two parallel FET devices fabricated on the flake in Figure 1(a). They have a gate length of 2 m and gate width of 3.5 m.
Importance of Streptococcus pneumoniae in Community-Acquired Pneumonia

T o understand the burden of Streptococcus pneumoniae in community-acquired pneumonia (CAP), one must first understand the burden of CAP in our communities. Jokinen et al (1) summarized the results of 10 population-based studies conducted between 1964 and 1982. The overall rate of pneu monia per 1000 persons per year ranged from eight to 15. The attack rates for pneumonia are highest at the extremes of age - for those younger than five years of age, the incidence is 34 to 36/1000/year, while for those 70 years of age and older it is 18 to 21/1000/year, and for those 75 years and older, it is 34.2/1000/year (! ). Koivula et al (2) studied all residents 60 years of age and older in a Finnish township, and found that 14/1000/year devel oped pneumonia and most, 10.2/1000/year, were community acquired. and
Improving Image Restoration with Soft-Rounding: Supplementary Material

(1) where y is the degraded observation, K is the block Toeplitz matrix representation of the convolution kernel k, zI ,wI , μI are the auxiliary variable, the Lagrange multiplier, and the penalty parameter for our distinct pixel value regularizer respectively, and D,ΓN are the linear transform and the corresponding regularizer in the transformed domain. The first two terms are quadratic on x, while the regularizer ΓN is usually a non-smooth term on x, which poses challenges for a direct numerical solution. For illustration purposes, we provide two ΓN examples and their corresponding solutions for the x subproblem. Example 1 We first consider the gradient-based `0 regularizer [8, 11, 12], which has been used as the baseline method for text image/pattern image deconvolution in Sec. 4.1 and 4.2:
“ Revolving Door ” In Psychiatric Units Seems To Remain a Common Phenomenon in the 21 st Century

Objective To assess the frequency of readmissions and the characteristics of patients undergoing two or more hospitalizations for the same psychiatric condition. Method Analyses of retrospective data from medical records of patients admitted to the Intensive Mental Healthcare Unit of Santos, Brazil between January 2010 and August 2016. Psychiatric patients admitted to the unit at least three times were considered to fulfill the “revolving door” criteria. Results From a total of 2579 admissions in the period of the study, 636 (24.6%) were considered to be “revolving door” cases. Patients fulfilling this “revolving door” criteria were younger (p=0.001), predominantly male (59.1%), and remained hospitalized for 4.8 days longer than other patients (p=0.01). The most frequent diagnoses for patients fulfilling the “revolving door” criteria were non-affective psychotic disorders (39.6%) and cases of use of psychoactive substances (30.3%). It was common for patients to present a combination of two or more diagnoses. Conclusion Nearly one quarter of patients admitted to a specialized healthcare unit in Santos, Brazil was cases of “revolving door”.
Making Innovators, Building Regions

knowledge into something new, different, and unprecedented that also has social and economic value. In the course of blending and weaving, innovators deploy their own talents and skills, but they also draw upon local resources such as an educated workforce, local firms, and government partners. In short, innovators emerge from distinct places and do their work in a particular, local context. Regions that succeed in fostering innovators are culturally vibrant and economically prosperous. Some of these places— such as California’s Silicon Valley, Massachusetts’s Route 128, and North Carolina’s Research Triangle Park— are a source of endless fascination and imitation. These highly innovative locales are economically diverse and usually feature a mix of entrepreneurial startups and mature anchor firms that create wellpaying jobs. These jobs, in turn, produce high incomes and a solid tax base that supports good local schools, public universities, and a robust infrastructure— each of which enable and feed the business sector in a mutually reinforcing cycle. Mayors, university presidents, and chambers of commerce are constantly striving to turn their towns into the next Silicon Alley, Silicon Desert, or Silicon Forest. But how do you do it? What are the ingredients? Are there recipes? I have been studying the making of such innovative places for more than twentyfive years. I began my career with the 1994 book The Geography of Innovation. In that work, I used an econometric model to identify the locationspecific determinants of innovative regions, and I found that successful clusters require a research university, industrial R&D, skilled workers, and the presence of related industries. Because a disproportionate share 6 Making Innovators, Building Regions
Automatic Construction of Domain-Specific Knowledge Graphs from Wikidata

Wikidata is a large open-source general purpose knowledge graph which contains information about a huge number of real-world entities. We develop a pipeline which, given a domain of interest such as sport or technology, extracts a domain-specific seed knowledge graph from Wikidata. We then compare methods which can be used to generalize the seed knowledge graph to a complete domain-specific knowledge graph. The resulting domain-specific graphs can be used for question-answering, content search or content recommendation. Additionally, they may provide more tractable subsets of Wikidata for application of either logical reasoning or statistical techniques such as entity embeddings.

QUALITY OF MILK SOLD IN WEST GARO HILLS, MEGHALAYA

Meghalaya is deficient in milk production. Government of India has taken initiatives to promote the dairy sector, yet Meghalaya could only contribute around 6.6% of the total amount of milk produced by the North-Eastern States. Hence, to shorten the gap between the demand of milk and shortage of supply, the sellers are tempted to adulterate the milk as a result 96% of the milk were found non-confirmatory during the National Survey of Milk Adulteration by FSSAI (Food Safety and Standard Authority, Govt. of India). Very less work had been done to access the quality of milk in remote areas like Garo Hills, Meghalaya. So, it becomes very important to check the quality of milk in this area. Thus, a study had been done to check the physic-chemical characteristics of milk, microbial load and detection of adulterants in the milk sold in Garo Hills. It was found that all the milk samples were adulterated with water, had cane sugar in one sample and the microbial load been higher in all the samples.

Designing Computer-Assisted Translation Software for Trainee Translators Based on Classroom Parallel Corpora

The machine translation industry’s shift from Statistical Machine Translation (SMT) to Neural Machine Translation (NMT) has recently brought renewed focus on Computer-Assisted Translation (CAT) in translation pedagogy. The purpose of this paper is to propose a CAT tool based on classroom parallel corpora. Trankit, a CAT software prototype the author designed, offers a powerful web-based platform for trainee translators along with a wide range of advanced search options and linguistic information such as concordance lines, syntax trees, and frequency information so that students can make full use of their corpus databases. Section 2 and 3 are literature reviews on parallel corpora and CAT, which are the central concepts forming the theoretical background of the design. Section 4 asserts the necessity of a new CAT tool in relations to these two underlying concepts. Section 5 presents the user interface of the program, exploring applications of CAT in translation training.
EMPIRICAL STUDY ON NURSES INTENTION TO LEAVE MEDIATED BY PERSON - ORGANIZATION FIT AT MULTI-SPECIALITY HOSPITALS, BANGALORE

BACKGROUND: Health is wealth. Life is more precious for everyone and health cannot be earned. In the health care organization, the nurse turnover may detract the quality of care. To mitigate such a problem, it is better to examine nurses' intentions to leave. OBJECTIVES: This study attempts to test the effects of workplace social context and job context and its relationship with the person - organization fit towards turnover intention of nurse's at multi-speciality hospitals, are the focus of the study. METHODS: A structured survey questionnaire measures the responses from 847 nurses of multi- speciality hospitals using stratified random sampling method. Descriptive analysis, Correlation, and ANOVA were used. Confirmatory Factor Analysis using AMOS 20.0 validated the measurement model. RESULTS: The results show that workplace social context and job context have a positive relationship with the person - organization fit, with r =. 233**, r =. 284**, and p < . 05. In turn, the person - organization fit has a significant negative relationship with intent to leave, as shown by r = - . 383**. The χ 2 statistics were significant and sensitive to sample size and model complexity. The fit indices were good and showed an acceptable fitting model. CONCLUSION: Job context has a greater impact than workplace social context on turnover intention of nurses through person - organization fit. Job context is closely related to person - organization fit. Higher the person - organization fit lowers the intent to leave among the nurses in multi-speciality hospitals.
Belted Sum Decompositions in Nested Links

Adams proved that FALs are always hyperbolic [2]. An FAL is a link in which each twist of two strands and has been augmented. The notion of augmenting a twist region was formalized by Adams in [2]. The process consists of embedding a trivial component called a crossing circle around the region and removing all full twists. An illustration of this process can be seen in Figure 1. One convenient feature of an FAL is that each crossing disk is a thrice punctured sphere where the punctures are the intersections of two knot circles with the crossing disk and the boundary of the crossing disk.
WIND TUNNEL EXPERIMENTS AND CFD SIMULATIONS STUDY TO INVESTIGATE THE EFFECTS OF ROUGHNESS ON SHIP RESISTANCE

A study on the influence of hull roughness on ship efficiency will be discussed in this report. The overall aim of this work is to show that directly comparing hull roughness from experiment and numerical work requires more than just one roughness characteristics, i.e average roughness height k". Other components such as solidity, slope, and compactness, would directly influence the flow. This work also further emphasises the importance of using sand grain equivalent roughness height k# as a roughness reference. The increase of total drag coefficient (C%) on a ship model due to k"and k# for both experiment and numerical investigation will be discussed.

Surface Segregation of Ternary Alloys: Effect of the Interaction between Solute Elements

Ternary alloys have been developed for a wide range of applications and surface segregation of ternary alloys has a decisive impact on their performance. Different from binary alloys, in which surface energy is usually the dominant factor, the interaction between solute elements has a noticeable effect on the surface segregation behavior of ternary alloys. As a practical example, Pd‐based ternary alloys have been proposed as promising candidates for hydrogen separation membranes due to their excellent permeability and selectivity. In the present work, surface segregation of Pd‐Cu‐Ag and Pd‐Cu‐Mo ternary alloys in both vacuum and hydrogen atmosphere is investigated. X‐ray photoelectron spectroscopy and low energy ion scattering spectroscopy analyses reveal that the segregation trend of the outermost atomic layer is not always the same as that of the near‐surface region. A thermodynamic model is developed to describe the surface segregation of ternary alloys. The results of the model are in good qualitative agreement with experimental results. Furthermore, calculations for other ternary alloy systems confirm that the model provides a simple but universal method for surface segregation in ternary alloys. The results can also be considered as basic guidelines to design novel ternary alloys for various applications.
Taking a Deeper Look at Co-Salient Object Detection

Co-salient object detection (CoSOD) is a newly emerging and rapidly growing branch of salient object detection (SOD), which aims to detect the co-occurring salient objects in multiple images. However, existing CoSOD datasets often have a serious data bias, which assumes that each group of images contains salient objects of similar visual appearances. This bias results in the ideal settings and the effectiveness of the models, trained on existing datasets, may be impaired in real-life situations, where the similarity is usually semantic or conceptual. To tackle this issue, we first collect a new high-quality dataset, named CoSOD3k, which contains 3,316 images divided into 160 groups with multiple level annotations, i.e., category, bounding box, object, and instance levels. CoSOD3k makes a significant leap in terms of diversity, difficulty and scalability, benefiting related vision tasks. Besides, we comprehensively summarize 34 cutting-edge algorithms, benchmarking 19 of them over four existing CoSOD datasets (MSRC, iCoSeg, Image Pair and CoSal2015) and our CoSOD3k with a total of ∼61K images (largest scale), and reporting group-level performance analysis. Finally, we discuss the challenge and future work of CoSOD. Our study would give a strong boost to growth in the CoSOD community. Benchmark toolbox and results are available on our project page.
Detecting strawberry cultivar misidentification in the Philippines using single nucleotide polymorphism markers from the anthocyanin reductase gene

BACKGROUND Commercial strawberry production in the Philippines is done by small-holder farmers in La Trinidad, Benguet, where the climate is conducive for optimal growth of this temperate crop. However, these farmers are not cognizant of the importance of proper cultivar identification, particularly during runner propagation, distribution, and transplanting. Thus, there is a high likelihood that misidentification of commonly grown cultivars has taken place. OBJECTIVE The study aimed to develop single nucleotide polymorphism markers and use them to detect possible misidentification among strawberry cultivars. METHODS Leaf samples from several cultivars were obtained from farmers and the germplasm collection of a local university in La Trinidad, Benguet, Philippines. Expressed sequence tags from the ANR gene were screened for putative SNPs. Eleven SNP markers were developed and used to discriminate among the collected samples. RESULTS The SNP markers grouped the cultivars into five genotypic clusters with seven distinct genotypic identities. Clustering analysis revealed inconsistencies between the farmers’ identification and the molecular classification. ‘Sweet Charlie’ samples were assigned to four genotypic clusters and ‘Strawberry Festival’ samples were grouped into three separate clusters. CONCLUSION There is a high probability that cultivar misidentification has indeed occurred. The molecular markers developed in this study could assist in future cultivar verification efforts, germplasm management, and breeding programs.
