Theory of Casimir-Polder forces

We consider the energy shift for an atom close to a nonmagnetic body with a magnetic moment coupled to a quantized magnetic field. The corresponding repulsive Casimir-Polder force is obtained for a perfect conductor, a metal, a dielectric medium, with dielectric properties modeled by a Drude formula, and a superconductor at zero temperature. The dielectric properties of the superconductor are obtained by making use of the Mattis-Bardeen linear-response theory and we present some useful expressions for the low-frequency conductivity. The quantum dynamics with a given initial state is discussed in terms of the well-known Weisskopf-Wigner theory and is compared with corresponding results for a electric-dipole coupling. The results obtained are compatible with a conventional master-equation approach. In order to illustrate the dependence on geometry and material properties, numerical results are presented for the ground state using a two-level approximation.
Convolutional Neural Network With Adaptive Regularization to Classify Driving Styles on Smartphones

Driving style evaluation by smartphones depends on the quality of the features extracted from sensors data. Typically, these features are extracted based on experiments, expertness, or heuristics. In more modern approaches, some automatic methods such as convolutional neural network (CNN) are used to extract features including obvious and hidden ones. We also used the CNN on acceleration data collected by smartphones to extract the knowledge regarding driving style, vehicle, environment, and human characteristics. We found that this novel idea was more successful for evaluating the driving style compared with the previous machine learning algorithms. However, we faced over-fitting in the training process of the CNN and to avoid this, we proposed the state-of-the-art learning method applying two adaptive regularization schemes called adaptive dropout and adaptive weight decay. To evaluate these techniques, first, we checked the results on three popular large-scale datasets. When we proved the efficiency, we utilized them on two transportation data sets. In transportation-modes dataset, the accuracy was at least 95.8%’; and regarding the driving-style dataset, the classification accuracy was 95%. Thus, the adaptive regularized CNN is an amazing option for driving style evaluation on smartphones.
PD-1 blockade synergizes with oxaliplatin-based, but not cisplatin-based, chemotherapy of gastric cancer

ABSTRACT Preclinical experimentation revealed that established cancers treated with the immunogenic cell death (ICD) inducer oxaliplatin are sensitized to immune checkpoint inhibitors targeting PD-1. In contrast, no such sensitizing effect is observed when cisplatin, a non-immunogenic cell death inducer is used. Two randomized phase III clinical trials targeting unresectable gastric and gastro-esophageal junction carcinomas apparently validate this observation. Thus, oxaliplatin-based chemotherapy (together with capecitabine or 5-fluorouracil plus leucovorin) favorably interacted with nivolumab, yielding improved outcome. In contrast, the outcome of cisplatin-based chemotherapy (together with capecitabine or 5-fluorouracil) failed to be improved by concomitant treatment with pembrolizumab. These clinical findings underscore the importance of choosing appropriate ICD-inducing cytotoxicants for the development of chemoimmunotherapeutic regimens. Unfortunately, the FDA and EMA have approved PD-1 blockade in combination with “platinum-based chemotherapy” without specifying the precise nature of the platinum-containing drug. This is a non sequitur. Based on the available clinical data, such approvals should be restricted to the use of oxaliplatin.
Maximal Oxygen Intake, Endurance Running Performance, and Body Composition in College Women

Abstract The purpose of the present study was to determine the validity of Cooper's 12-min. endurance run test in 36 college women using max VO2 as the criterion of validity. Max VO2 was measured using the Balke treadmill test (mean = 2.29 L/min; 38.9 ml/kg/min). Percent body fat (mean = 21.8%) and lean body weight (mean = 45.0 kg.) were also determined in 17 women from body density measurements (underwater weighing). A significant correlation of r = . 67 was obtained between the endurance run and max VO2 (ml/kg/min), which increased to r = . 71 when the correlation was corrected for attenuation from test unreliability in max VO2 (r 11 = .95) and the run (r 22 = .78). One standard error for predicting max VO2 from the run scores was within ± 9% (3.4 ml/kg) and ± 13% (299 ml/min) of predicted values, respectively. Cooper's regression equation to predict max VO2 from the run scores in men underestimated the average max VO2 in women by 18%. Lean body weight correlated r = . 49 with the run scores and r = . 76 wi.
Energy savings and usability of zero-client computing in office settings

ABSTRACT This study provides a detailed comparison of the power consumption, usability, and applicability of virtual machines (VMs)—accessed through zero-client devices—and traditional laptop computers in office settings. The study analyzed high-level plug loads across two office spaces, one using traditional laptops, the other using zero clients. In addition, the individual power consumption of four workstations was monitored and compared. Each workstation user switched between using a laptop or zero client for one week and then using the alternate system the second week. Results of the high-level and workstation analysis show that average workstation plug loads are lower for occupants using zero clients. However, this does not include power consumed by the data center managing VMs. This study calculates the affiliated data center power draw of VMs and shows that server-related loads push total zero-client computing energy higher than that of traditional laptops. Finally, a questionnaire was administered to building occupants to determine the appropriateness of zero-client computing for various user groups, with the results indicating that VMs are most appropriate for more basic software functions. The findings of this study suggest that advances in server technology can help improve both the overall efficiency and the usability of zero-client computing.
Durability performance of a lime stabilized expansive soil with egg shell ash as a subsidiary admixture

Stabilization is broadly classified as mechanical and chemical stabilization. Lime stabilization is the most commonly adopted method for stabilising expansive soils. In recent years, lime has been combined with other waste materials for improved performance in stabilization. One such waste is egg shell waste, generated by the poultry industry. Calcination of egg shell waste results in the formation of egg shell ash (ESA) which has a chemical composition very similar to that of quick lime. This investigation focuses on the potential of ESA as an auxiliary additive for lime in the stabilization of expansive soils. The initial consumption of lime of the expansive soil was determined using the Eades and Grim pH test. The lime content in the stabilization process was modified with ESA up to 0.5% in increments of 0.1%. Unconfined compression strength test samples of dimensions 38 mm x 76 mm were cast and cured for a period of 21 days and tested for their strength. The durability of the samples was also evaluated by subjecting the samples to 1, 4, 7, and 10 cycles of wetting and drying. The results of the investigation revealed that 0.2% ESA was the optimal dosage of additive to lime stabilization for improved performance.
Feasibility, Appropriateness, and Willingness to Use Virtual Reality as an Adjunct to Counseling among Addictions Counselors

Abstract Introduction Research suggests that virtual reality (VR) experiences can be helpful as adjunctive tools in psychotherapy for some mental health conditions. VR is a computer-generated experience that produces a feeling of being immersed in a different environment. VR experiences could be useful in the treatment of substance use disorders, and several are currently being tested. However, few psychotherapists report using VR experiences in their practices, even when doing so is well-supported. Understanding key barriers and concerns about using VR among drug/alcohol counselors is important to ultimately encouraging adoption. Methods Licensed counselors (N = 101) who provide treatment to clients with substance use disorders were recruited via email Listservs, professional organizations, and social media. Participants viewed a 15-minute educational video about VR and then completed a survey of their views about using it with their clients. Results Most clinicians (82%) believed they would be likely to use a VR experience in drug/alcohol counseling, and 81% believed it would be appropriate for most of their clients. A minority (19%) noted important concerns, including that their clients may be skeptical of it (15%), cost (14%), and space (10%). Those who had cost and space concerns were less likely to report high use intentions (OR = 0.29 and OR = 031, both p < .05, respectively). Conclusions Findings suggest that addictions counselors are eager to use VR, but key barriers should be addressed. VR developers should incorporate features to encourage trust among users, design experiences for small spaces, and explore ways of supporting the purchase of VR systems for counselors.
Event model retrieval and daily interference

The differential fan effect was used to assess the influence of periods of daily, generalised interference. Experiment 1 replicated the differential forgetting effect as a control for the other experiments. Experiment 2 involved fact learning in either the morning or the evening with a 12-hr testing delay. It might be expected that experiencing more generalised interference during the retention interval would impair memory, but no differences in response times were observed, and only very small differences in the error rates were observed. Experiment 3 replicated Experiment 2 but with a 24-hr delay. In this way, the influence on memory of the proximity of daily, generalised inference to the learning experience could be assessed. Although one might expect worse memory when more interference occurred closer to the learning phase, no clear differences were observed. This is consistent with the idea that event model memory is relatively stable soon after encoding.
A street-level assessment of greenhouse gas emissions associated with traffic congestion in the city of Nairobi, Kenya

Traffic congestion significantly contributes to climate change due to the emissions of Greenhouse Gases (GHGs) such as Carbon Dioxide (CO2), Nitrous Oxide (N2O), and Ozone (O3). Rapid urbanization and poor planning coupled with increased motorization and fragmented public transport system in cities such as Nairobi have led to increased vehicular emissions especially during heavy traffic along the various roads and within the Central Business District (CBD). To reduce GHG emissions in the urban transport sector, institutional coordination and relevant policy tools must be considered. This study aimed at estimating CO2 emissions from different vehicles during traffic congestion, using Uhuru Highway as a case study. The relationship between traffic congestion and CO2 emissions was analyzed using qualitative and quantitative methods, through a bottom-up approach. Questionnaires were administered to get individual vehicle characteristics and opinions on the best actions for the reduction of CO2 emissions along Uhuru Highway in Nairobi. The Average Annual Daily Traffic (AADT) for different vehicles from 2014 to 2019 was used to estimate the CO2 emissions. Results showed that private cars predominate over other vehicle types, contributing to 73% of the total CO2 emissions in Nairobi (CBD). Private cars are the highest contributor of CO2 emissions with a total of 25.3 million Carbo dioxide equivalent (gCO2e), between 2014 and 2019. In comparison, Public Service Vehicles, commonly referred to as Matatus emitted 6.89 million gCO2e, Light Commercial Vehicles (1.82 million gCO2e), Heavy Goods Vehicles (251,683 gCO2e), and motorcycles (181,054 gCO2e). To minimize CO2 emissions, the study recommended the enforcement of strong mobility policies to control the high motorization rate. One of these policies is the prioritization of the development of the mass public transport systems to achieve the potential health, economic and environmental gains within the CBD.
Performance assessment of different roof integrated photovoltaic modules under Mediterranean Climate

Many countries, for aesthetic purposes, offer economic advantages (tax deductions, incentives, etc.) for the installation of building integrated photovoltaic modules (BIPV), with water-tightness capability and adequate mechanical resistance in order to substitute tile covering or part of it. Nevertheless, poor or absent ventilation under BIPV panels could cause them to overheat and reduce their efficiency. It is well established that the presence of an air gap between a photovoltaic (PV) module and roof covering facilitates ventilation cooling under the device and consequently reduces cell temperature and improves its performance. In this study, we investigated the thermal performance of PV modules installed in a real scale experimental building over a traditional clay tile pitched roof in Italy for almost one year (from August 2009 to June 2010). One PV module was rack-mounted over the roof covering with a 0.2 m air gap; the others were fully integrated and installed at the same level of the roof covering (one with an air gap of 0.04 m, the other mounted directly in contact with the insulation). Temperature and heat flux measurements for each panel, and environmental parameters were recorded. Experimental results demonstrate that even though the rack-mounted PV module constantly maintains cell temperature below that of the other full-building integrated modules, due to the presence of a higher air gap, the difference in the energy produced by the PV modules estimated for the entire monitoring period is less than 4%.
The Effect of Intrinsic and Extrinsic Rewards for Developers on Information Systems Project Success

Project failure in information sytems development continues to plague organizations. A lack of intrinsic and extrinsic rewards for developers may be a cause of such failure. A survey instrument was created using existing project success scales and items based on structured interviews with 12 IS project managers. Two hundred two members of the Project Management Institute completed the survey. After rigorous validation, path analysis (an extension of multiple regression that simultaneously tests more complex relationships) showed that use of intrinsic rewards predicted client satisfaction and perceived quality (but not on-time and within-budget implementation success), whereas use of extrinsic rewards predicted implementation success (but not satisfaction or quality). Future researchers might investigate reasons for these complementary findings. Managers might use the findings in efforts to improve information systems project success.
Design suggestions for greater teamwork, communication and security in hospital emergency departments

This paper presents design recommendations based on a qualitative study for enhancement of teamwork, communication and security in emergency departments. Considering the crucial role of the emergency department in providing urgent care, the design of physical environments to facilitate immediate, efficient and effective patient care are of significant importance. The study adopted an exploratory approach, where levels of visibility, teamwork, communication and security were explored in five emergency departments using one-on-one interviews. Data collection and analysis involved interviews with medical staff and a textual analysis of interview transcripts. The study findings support the view that teamwork, communication and security can be improved by the physical layout in an emergency department, as well as other environmental factors including acoustics, lighting, accessibility of supplies, entrance control and privacy. The study provides tangible design guidelines for architects, healthcare planners and emergency department managers to support design decisions and strategies that promote emergency department effectiveness.
INPLANE BUCKLING OF ANISOTROPIC RINGS

Inplane buckling of laminated rings is considered based on a non-linear theory for stretching and bending of geometrically and materially symmetric anisotropic beams having constant initial curvature in their plane of symmetry. The ring is formed by initially curving the laminated beam out of the plane of the laminate. For the kinematics, the geometrically exact one-dimensional (1-D) measures of deformation are specialized for small strain, and a 1-D constitutive law is developed via an asymptotically correct dimensional reduction of geometrically non-linear 3-D elasticity. The reduction assumes small strain and comparable magnitudes for the initial radius of curvature R and the wavelength of deformation along the beam reference line. Other small parameters include the ratio of cross-sectional thickness h to initial radius of curvature (h/R) and the ratio of cross-sectional thickness to cross-sectional width (h/b). In spite of a very simple final expression for the second variation of the total potential, it is shown that the only restriction on the validity of the buckling analysis is that the prebuckling strain remains small. The buckling load obtained exhibits features not found in published formulae.

Available DETERMINATION OF SUBPUBIC ANGLE IN SAUDI POPULATION

: Background: Sex determination of unknown skeletal material is one of the most vital determinations made by forensic anthropologists. The pelvis is probably the most accurate bone from which sex is determined. In that context, the subpubic angle showed correct gender identification in over 98% of cases. The subpubic angle was wider in females than in males. Moreover, it has been ascertained that signiﬁcant differences exist between populations in subpubic angle measurements. Also, it was found that the subpubic angle is affected by ethnicity. So, the aim of this work was to quantify the subpubic angle in Saudi males and females to establish national parameters and also to determine whether any statistically significant differences exist between males and females and other population groups. Material and method: The subpubic angle was measured in the antero-posterior radiographs of 33 adult Saudis male and female. The data was analyzed using SPSS version 16 for statistical analysis . Result: The subpubic angle for males ranged from 69° to 117° with a mean ± SD [91.10 ± 13.88] and for females from 114° to 155° with a mean ± SD [132.29 ± 13.44]. The angles were significantly wider in female than males [P<0.05]. Furthermore, the results for both sexes were statistically significant in comparison to previous established results for other population groups . Conclusion: The subpubic angle of Saudi population can be considered as an obtuse angle in females but overlaps between acute and obtuse in males. It also shows regional variations and hence, reinforces the need for population specific parameters which are useful to obstetricians, anthropologists and forensic specialties.
SERUM ZINC AND COPPER LEVELS IN HIV POSITIVES PATIENTS EUROPEAN JOURNAL OF PHARMACEUTICAL AND MEDICAL RESEARCH

Background: Micronutrient deficiencies, which are commonly observed with advanced HIV disease, have been associated with higher risks of HIV disease progression and mortality. Objectives: The Aim of the present study was to assess Serum Zinc and copper levels among IV Patients and correlate it with age, sex and duration of infection. Methodology: Descriptive cross-sectional study was conducted in the Dhiraj hospitals, Sumandeep vidypeeth university, SBKS Medical College, blood samples obtained from 150 HIV sero-positive individuals and age and gender matched healthy controls were analyzed for zinc, and copper using spectrophotometer. Data were analyzed by Statistical computer software. Results: The (mean±SD) of Serum copper and zinc were (22.9±1.7mg/dl, 7.1±0.9mg/dl) in patients and (16.3±3.3 mg/dl, 11.5±3.0 mg/dl) in control group, respectively. The Serum Zinc level was significantly decreased in HIV patients (P value, 0.05) while Serum Copper level was significantly increased compared to healthy individual. There was strong negative correlation between Serum zinc levels and duration of HIV disease (r = -0.5, p value =0.00) and age of patients (r = - 0.58 p value = 0.01). There was weak positive correlation between copper level and duration of HIV disease (r =0.16, p value =0.223) and age of patients (r =0.4, p value =0.05). The differences in Serum copper and Zinc levels were insignificant between male and female in HIV patients (p value > 0.05). Conclusion: This study indicates that Zinc and copper levels are altered in HIV infected patients with more decreased Zinc level suspected with increased duration of HIV disease.
Telavancin (TLV) is Active Against Experimental Aortic Valve Endocarditis Caused by 1 Daptomycin-Resistant (DAP-R) Methicillin-Resistant Staphylococcus aureus (MRSA) 2 Strains 3

24 We compared the efficacy of TLV and DAP in an experimental rabbit endocarditis model caused 25 by two clinically-derived DAP-R MRSA strains. TLV treatment significantly reduced MRSA 26 densities in all target tissues and increased the percentage of these organs rendered culture- 27 negative as compared to untreated control or DAP-treated animals. These results demonstrate 28 that TLV has potent in vivo efficacy against DAP-R MRSA isolates in this invasive endovascular 29 infection model. 30 investigation use MRSA IE models and TLV viable alternative for the treatment of IE strains other glycopeptide or lipopeptide
