VR Color Picker: Three-Dimensional Color Selection Interfaces

In this paper, we propose a 3D color picker for virtual reality (VR) systems. Using the proposed color picker, the RGB and HSV color spaces are displayed in 3D shape, and a color can be selected through a one-step interaction by pointing at a location inside the color space with a 3D pointing device. This process is very simple compared with the multistep color selection interactions required for existing VR color pickers. Since the interior of the color space is not visible, we also propose three types of user interfaces that show the interior of the color space. These interfaces either cut out a portion of the color space, show cross-sections of the color space, or show discrete samples placed in the color space. We conducted user experiments on the color selection time, color selection accuracy, and usability and proved the usefulness and effectiveness of the proposed VR color picker.
Association Between the LZTFL1 rs11385942 Polymorphism and COVID-19 Severity in Colombian Population

Genetic and non-genetic factors are responsible for the high interindividual variability in the response to SARS-CoV-2. Although numerous genetic polymorphisms have been identified as risk factors for severe COVID-19, these remain understudied in Latin-American populations. This study evaluated the association of non-genetic factors and three polymorphisms: ACE rs4646994, ACE2 rs2285666, and LZTFL1 rs11385942, with COVID severity and long-term symptoms by using a case-control design. The control group was composed of asymptomatic/mild cases (n = 61) recruited from a private laboratory, while the case group was composed of severe/critical patients (n = 63) hospitalized in the Hospital Universitario Mayor-Méderi, both institutions located in Bogotá, Colombia. Clinical follow up and exhaustive revision of medical records allowed us to assess non-genetic factors. Genotypification of the polymorphism of interest was performed by amplicon size analysis and Sanger sequencing. In agreement with previous reports, we found a statistically significant association between age, male sex, and comorbidities, such as hypertension and type 2 diabetes mellitus (T2DM), and worst outcomes. We identified the polymorphism LZTFL1 rs11385942 as an important risk factor for hospitalization (p < 0.01; OR = 5.73; 95% CI = 1.2–26.5, under the allelic test). Furthermore, long-term symptoms were common among the studied population and associated with disease severity. No association between the polymorphisms examined and long-term symptoms was found. Comparison of allelic frequencies with other populations revealed significant differences for the three polymorphisms investigated. Finally, we used the statistically significant genetic and non-genetic variables to develop a predictive logistic regression model, which was implemented in a Shiny web application. Model discrimination was assessed using the area under the receiver operating characteristic curve (AUC = 0.86; 95% confidence interval 0.79–0.93). These results suggest that LZTFL1 rs11385942 may be a potential biomarker for COVID-19 severity in addition to conventional non-genetic risk factors. A better understanding of the impact of these genetic risk factors may be useful to prioritize high-risk individuals and decrease the morbimortality caused by SARS-CoV2 and future pandemics.
Modelling vortex-vortex and vortex-boundary interaction

The motion of two-dimensional inviscid, incompressible fluid with regions of constant vorticity is studied for three classes of geophysically motivated problem. First, equilibria consisting of point vortices located near a vorticity interface generated by a shear flow are found analytically in the linear (small-amplitude) limit and then numerically for the fully nonlinear problem. The equilibria considered are mainly periodic in nature and it is found that an array of equilibrium shapes exist. Numerical equilibria agree well with those predicted by linear theory when the amplitude of the waves at the interface is small. The next problem considered is the time-dependent interaction of a point vortex with a single vorticity jump separating regions of opposite signed vorticity on the surface of a sphere. Initially, small amplitude interfacial waves are generated where linear theory is applicable. It is found that a point vortex in a region of same signed vorticity initially moves away from the interface and a point vortex in a region of opposite signed vortex moves towards it. Configurations with weak vortices sufficiently far from the interface then undergo meridional oscillation whilst precessing about the sphere. A vortex at a pole in a region of same sign vorticity is a stable equilibrium whereas in a region of opposite-signed vorticity it is an unstable equilibrium. Numerical computations using contour dynamics confirm these results and nonlinear cases are examined. Finally, techniques based on conformal mapping and the numerical method of contour dynamics are presented for computing the motion of a finite area patch of constant vorticity on a sphere and on the surface of a cylinder in the presence of impenetrable boundaries. Several examples of impenetrable boundaries are considered including a spherical cap, longitudinal wedge, half-longitudinal wedge, and a thin barrier with one and two gaps in the case of the sphere, and a thin island and ‘picket’ fence in the case of the cylinder. Finite area patch motion is compared to exact point vortex trajectories and good agreement is found between the point vortex trajectories and the centroid motion of finite area patches when the patch remains close to circular. More exotic motion of the finite area patches on the sphere, particularly in the thin barrier case, is then examined. In the case when background flow owing to a dipole located on the barrier is present, the vortex path is pushed close to one of the barrier edges, leading to vortex shedding and possible splitting and, in certain cases, to a quasi-steady trapped vortex. A family of vortex equilibria bounded between the gap in the thin barrier on a sphere is also computed.
Adenovirus DNA Polymerase Loses Fidelity on a Stretch of Eleven Homocytidines during Pre-GMP Vaccine Preparation

In this study, we invented and construct novel candidate HIV-1 vaccines. Through genetic and protein engineering, we unknowingly constructed an HIV-1-derived transgene with a homopolymeric run of 11 cytidines, which was inserted into an adenovirus vaccine vector. Here, we describe the virus rescue, three rounds of clonal purification and preparation of good manufacturing practise (GMP) starting material assessed for genetic stability in five additional virus passages. Throughout these steps, quality control assays indicated the presence of the transgene in the virus genome, expression of the correct transgene product and immunogenicity in mice. However, DNA sequencing of the transgene revealed additional cytidines inserted into the original 11-cytidine region, and the GMP manufacture had to be aborted. Subsequent analyses indicated that as little as 1/25th of the virus dose used for confirmation of protein expression (106 cells at a multiplicity of infection of 10) and murine immunogenicity (108 infectious units per animal) met the quality acceptance criteria. Similar frameshifts in the expressed proteins were reproduced in a one-reaction in vitro transcription/translation employing phage T7 polymerase and E. coli ribosomes. Thus, the most likely mechanism for addition of extra cytidines into the ChAdOx1.tHIVconsv6 genome is that the adenovirus DNA polymerase lost its fidelity on a stretch of 11 cytidines, which informs future adenovirus vaccine designs.
A New Proportionate Filtered-x RLS Algorithm for Active Noise Control System

The filtered-x recursive least square (FxRLS) algorithm is widely used in the active noise control system and has achieved great success in some complex de-noising environments, such as the cabin in vehicles and aircraft. However, its performance is sensitive to some user-defined parameters such as the forgetting factor and initial gain. Once these parameters are not selected properly, the de-noising effect of FxRLS will deteriorate. Moreover, the tracking performance of FxRLS for mutation is still restricted to a certain extent. To solve the above problems, this paper proposes a new proportional FxRLS (PFxRLS) algorithm. The forgetting factor and initial gain sensitivity are successfully reduced without introducing new turning parameters. The de-noising level and tracking performance have also been improved. Moreover, the momentum technique is introduced in PFxRLS to further improve its robustness and de-noising level. To ensure stability, its convergence condition is also discussed in this paper. The effectiveness of the proposed algorithms is illustrated by simulations and experiments with different user-defined parameters and time-varying noise environments.
Violence, displacement, contact, and attitudes toward hosting refugees

How do individuals’ personal experiences with various aspects of political violence affect their attitudes toward hosting conflict refugees? More specifically, how do their personal exposure to violence, their own personal experience of being displaced, and their recent contact with refugees influence these attitudes? To explore answers to these questions, we draw upon a recent survey of 2,400 Lebanese residents where we identify individuals who experienced violence during the Lebanese civil war (1975–90), those forced to flee their homes during that conflict, and those who enjoy recent contact with Syrian immigrant and/or displaced populations. We examine whether these distinct experiences affect respondents’ regard for members of the Syrian refugee population. Results demonstrate that historical exposure to violence and experience of displacement have no discernible impact on individual attitudes toward hosting refugees. We find much stronger evidence that attitudes are associated with whether individual respondents have had contact with Syrians in Lebanon; those with such interactions are significantly more likely to support hosting refugees, to consider hiring a refugee, or to allow one of their children to marry a refugee. Our findings suggest exposure to violence by itself does not correlate to positive sentiments toward refugees, especially over time. Further, finding ways to create positive contact between refugees and native populations may be associated with improving attitudes and relations between the two populations.
Smart Training of Alex Net u sing Fluorescein Angiography Fundus Images Implementing Selective Data Sampling

—This research paper pertains to the concept of preliminary detection of Posterior Capsular Opacification, Glaucoma and Genetic Diseases in the human eye using Alex Net, which is one of the earliest CNN found in the MATLAB. CNN are trained with specific layers using the given dataset taking blood vessels as the parameter for detecting pre-abnormalities from the images. The specific layers are used for reducing the time for training and detection. The layers have been chosen based on the different parameters like filters, rate of training, initial rate, statistical parameters and mathematical modelling. After this the system is trained for 100 to 1000 epochs in which the test image is chosen as input and is compared with disease affected and normal blood vessels. It is found that for first training the system had a detection with an accuracy of 50 to 60% and with subsequent training it had an efficiency of 80-90%
Identifying and Characterizing People with Dementia Not Accessing the Japanese Community-Based Integrated Care System Using Health Insurance Claims Data

Objective In the Japanese Community-Based Integrated Care System (CBICS), access to formal care services is based on voluntary consultations mainly from the families of people with dementia (PWD). The problem is that some people need services but do not consult their municipalities for various reasons. The purpose of this study is to examine the possibility of using health insurance claims data to identify and characterize these PWD. Methods Using health insurance claims data, we selected PWD prescribed with anti-dementia drugs. Of them, excluding those with a usage history of long-term care insurance services or other formal services, facility residents and deaths, we identified PWD not accessing the CBICS. We conducted a visit survey on their status, home care environment and reasons for not accessing services, a proposal for using services and a one-year follow-up. Result Based on the data of 1,809 late-stage elderly who resided in the Tamaki-cho, a town in Mie Prefecture, Japan, for a 2-month period, 16 PWD not accessing the CBICS were identified, and 15 PWD and their families participated in this study. Ten were men and 13 were physically and cognitively relatively independent. All lived with a family caregiver and refused services. Ten families needed but had not accessed the services due to refusal by PWD and other reasons. As a result, seven of these PWD started using long-term care insurance services or dementia prevention services. Conclusion PWD not accessing the CBICS can be identified using health insurance claims data. The results proved that the municipality has a cost-effective way of providing their services to PWD and their families, even if they have never consulted voluntarily.
Contribution to the knowledge of aquatic vegetation of montane and submontane areas of Northern Apennines (Italy)

The importance of wetlands for biodiversity conservation is widely recognized. ﻿Their relevance is crucial in the identification of habitat types included in the Habitats Directive 92/43/EEC and in the application of the following conservation measures. ﻿ Yet, several montane and submontane areas are poorly ﻿investigated from the phytosociological point of view. Here we studied aquatic communities of the Tuscan-Romagna Apennines in Italy using 52 vegetation plots dominated by hydrophytes collected in wetlands of natural and artificial origin. We analysed our data ﻿using a cluster analysis and identified 12 vegetation types that we classified as three vegetation classes Charetea intermediae, Lemnetea and Potamogetonetea, and ﻿two habitat types of conservation importance, as the hard oligo-mesotrophic waters with benthic vegetation of Chara spp. (Natura 2000 code 3140) and the natural eutrophic lakes with Magnopotamion or Hydrocharition (Natura 2000 code 3150). Our study highlights the diversity of aquatic habitats in montane and submontane areas of the Northern Apennines where water bodies are generally small and scattered. This study further highlights the important role of natural freshwater ecosystems for vegetation, but also the notable role of partly or entirely artificial water bodies in maintaining aquatic communities.

Assessment of Student Feedback from the Training Course and Instructor' Performance through the Combination of Clustering Methods and Decision Tree Algorithms

Assessment of instructor by students, in the last decade has been widely used in many universities, and there is always great interest in various aspects of assessment. Using data mining methods on data obtained from the assessment, it is possible to extract patterns that affect the quality of education.In this study, data collected from the survey forms of Turkish university students, which includes 28 items on the school and teachers,was evaluated. Due to the large number of items selected data set, first, using principal component analysis algorithm, the number of items was reduced from 28 items to two factors. Then using the two-step and Kohonen clustering algorithms on the assessment results, and comparing the two methods on the Silhouette basis, two-step cluster with creating three clusters with labels (satisfied, neutral, dissatisfied) and silhouette of 0.6 was considered as the best cluster analyse, then, using Quest decision tree algorithm on the results of a two-step clustering, and review of laws, items that play the most important role in the students' satisfaction and performance of instructor teachers , were identified.Accordingly, Question 7 (The course allowed field work, applications, laboratory, discussion and other studies) is more important than any other questions in predicting student satisfaction and their rating to the educators. The accuracy of the algorithm was calculate as 0.93 which has the good quality of classification.

Dissolved Organic Carbon Along a Meridional Transect in the Western North Pacific Ocean: Distribution, Variation and Controlling Processes

Dissolved organic carbon (DOC) in the ocean is one of the largest reduced and exchangeable organic carbon pools on Earth and plays important roles in carbon cycling and biogeochemical processes in the ocean. Here, we report the concentrations and distributions of DOC in water samples collected along a meridional transect in the western North Pacific (NP) Ocean in November 2019. Concentrations of DOC ranged from 33-102 μM, were higher in surface water, decreased rapidly with depth to 1,000 m, and then remained relatively constant. The labile fraction of DOC accounted for 20-40% of the surface bulk DOC and was respired very rapidly in the upper 200 m depth. The semi-labile fraction of DOC accounted for 15-20% of the surface bulk DOC and was exported downward and turned over at water depths of 200-2,000 m. The formation of NP Intermediate Water (NPIW) in the Kuroshio Extension (KE) region is a major process carrying some surface semi-labile DOC down. The Low concentrations of DOC (33-44 μM) were present in the entire water column below 1,000 m along the transect in the NP. Primary production and microbial consumption played major roles in the concentration and distribution of DOC in the euphotic zone, and hydrodynamic mixing and circulation of different water masses appear to be dominant factors controlling the distribution and dynamics of DOC in the deep water of the western NP.
Association Between Positive Mental Character and Humanistic Care Ability in Chinese Nursing Students in Changsha, China

Aim To investigate the status of positive mental characters and humanistic care ability among Chinese nursing students, and confirm the association between positive mental characters and humanistic care ability. Methods A cross-sectional survey was conducted. Nine hundred eighty-one Chinese nursing students were recruited from hospitals and community healthcare services in Changsha, Hunan, China. Three different self-reported questionnaires were applied: The Demographic Characteristics Questionnaire, Humanistic care ability of Nursing Undergraduates Assessment Scale and Positive Mental Characters Scale for Chinese College Students. Pearson correlation analysis and multiple liner regression analysis were performed to analyze the association between positive mental character and humanistic care ability for Chinese nursing students. Results The mean scores of nursing students' humanistic care ability and positive mental character were 125.94 ± 21.19, 233.18 ± 38.59, respectively. The Pearson correlation results showed that positive mental character (r = 0.655, P < 0.001) was significantly associated with humanistic care ability. Multiple liner regression analysis indicated that positive mental characters, four dimensions of courage, humanity, justice and transcendence in positive mental character, care from classmates were found to be independent predictors of humanistic care ability. Conclusion Positive mental characters are important considerations in the development, implementation and evaluation of humanistic care ability interventions.
OPTIMIZING THE ROLE OF LEADERSHIP AND STRENGTHENING WORK SPIRIT AS AN EFFORT TO INCREASE QUALITY WORK OUTCOMES

Quality of work is one of the main instruments that show the achievement of performance. For companies, performance is a necessity, which must be realized, as evidence of achieving goals. Therefore, it takes the involvement of all parties, especially the leadership. Leaders have an important role in influencing and inviting all employees to work totally in realizing company goals. In addition, the inherent optimism and enthusiasm is a supporting factor for improving performance. In this regard, this study aims to analyze and explain the possible influence of leadership and work motivation on improving performance. Methodologically, this research is quantitative based using multiple linear regression statistics. In collecting data, a questionnaire method was used, so that the answer scale was obtained. The results showed that the partial and simultaneous statistical results were in the significant category. That is, a good leader can encourage the creation of a productive work environment, an environment that breeds enthusiasm for work, and has a strong desire to give the best results. Likewise, work motivation has a real influence on the psychological state of employees, namely a self-motivation to be able to contribute to the interests of the company.Keywords: Work Quality, Work Spirit, Leadership Role
