Point clouds reduction model based on 3D feature extraction

Field: Computer Science (Physical Sciences)

Light detection and ranging (LIDAR) is a remote sensing method that scans the Earth's surface with high density to construct the digital elevation model (DEM). In this paper, we present a point clouds reduction model based on two 3D feature extraction techniques, namely: the sharp feature detection algorithm and feature extraction technique-based LIDAR point attributes. These techniques are used as initial selection criteria and are compared with the maximum and the minimum elevation criterion that gives reduction with the highest accuracy. However, point clouds reduction algorithms lead to high consumption of time to generate a reduced file with high accuracy, which prompts the need to propose a new model that considers the trade-off between the processing time and the accuracy. The results showed that the proposed model significantly reduced the processing time at the expense of accuracy reduction by 0.7% and 1.3% for the two used techniques respectively, which is acceptable for realistic applications.
Ultrahigh-Surface-Area Anatase Thin Films by Direct Oxidation of Ti Film with Hydrogen Peroxide

Field: Materials Science (Physical Sciences)

Nanostructured titania films are formed by directly oxidizing titanium with hydrogen peroxide. A low-temperature anneal transforms the films from an amorphous phase to anatase crystal. Surface-area measurements of the annealed nanostructured titania using the Brunauer, Emmett, and Teller method reveal a specific surface area of , the highest ever reported for a nanostructured titania film. The low-temperature anneal is compatible with heat-treated polyimide or polyester substrates for roll-to-roll processing of flexible electronics or solar cells.
Looking for the exotic $X_0(2866)$ and its $J^P=1^+$ partner in the $\bar{B}^0 \to D^{(*)+} K^- K^{(*)0} $ reactions

Field: Physics and Astronomy (Physical Sciences)

We propose two reactions, $\bar{B}^0 \to K^0 D^{+} K^-$ and $\bar{B}^0 \to K^{*0} D^{*+} K^-$, already measured at Belle, to look into the $J^P=0^+$, $X_0(2866)$ state and a $1^+$ partner of molecular $D^*\bar{K}^*$ nature, by looking at the $D^+ K^-$ and $D^{*+} K^-$ invariant mass distributions, respectively. Very clear peaks over the background are predicted and the branching ratios for the production of these states are evaluated to facilitate the task of determining the needed statistics for their observation. The fact that the $K^{*0} K^-$ mass distribution from accumulation of events of different reactions is already available, indicates that one is not far away from having the needed statistics to see peaks in the $D^{(*)+} K^-$ mass distributions, so far not yet analyzed.
Costs vs Benefits of Different Internationalization Strategies

Field: Business, Management and Accounting (Social Sciences)

We attempt to provide insights into the internationalization- performance (I-P) puzzle by introducing motives of internationalization into the I-P relationship. Motives of internationalization have been classified as - market seeking, strategic asset seeking, efficiency seeking and opportunity seeking. We then differentiate between the effects of different motives on operational costs and firm performance. Using a sample of 415 Indian firms from both services and manufacturing sector, we find that overall different motives of internationalization have a positive impact on firm performance. Although, firms incur higher operational costs while pursuing market seeking and opportunity seeking internationalization strategies.
Development and Validation of the Family Feedback on Child Welfare Services (FF-CWS)

Field: Psychology (Social Sciences)

Objective: The measurement of Family Feedback on Child Welfare Services (FF-CWS) is gaining prominence as an efficacy indicator and is coherent with concerns about family-centered practice and empowerment. The aim of this study was to develop and validate an instrument that would overcome the scarcity of psychometrically sound measures in this field. Methods: Following item construction and selection, exploratory and confirmatory factor analyses with a sample of 263 Spanish (52%) and Portuguese (48%) caregivers of children involved with CWS were conducted. Results: Three subscales were identified: Intervention Efficacy, Perception of Workers, and Satisfaction with the Intervention Process. In general, all dimensions showed good reliability, convergent, and criterion-related validity results. Multigroup analyses confirmed measurement invariance for both countries. Conclusions: The FF-CWS Questionnaire is a brief self-report measure that can be a useful assessment tool to frontline practitioners, agency managers, and policy makers for program evaluation and planning.

Abstract 5050: Testosterone supplementation in relation to prostate cancer in a US commercial insurance claims database

Field: Medicine (Health Sciences)

Abstract Background: Testosterone supplementation (TS) has dramatically increased in the United States (US). We conducted a study of TS and prostate cancer risk using a large US commercial insurance research database. Methods: From the HealthCore Integrated Research Database (HIRDSM), we selected men aged 30 years or greater who were new users of TS during 2007-2015. We selected two male comparison groups: 1) unexposed (matched 10:1); 2) new users of a phosphodiesterase type 5 inhibitor (PDE5i). Incident prostate cancer was defined as diagnosis of prostate cancer within four-weeks following prostate biopsy. Propensity scores and inverse probability of treatment weights were used in Poisson regression models to estimate adjusted incidence rates, incidence rate ratios (IRRs) and 95% confidence intervals (CI) using doubly robust estimation. Subgroup analyses included stratification by prostate cancer screening, hypogonadism, and follow-up time. Results: The adjusted prostate cancer IRR was 0.77 (95%CI: 0.68, 0.86) when comparing TS with the unexposed group and 0.85 (95%CI: 0.79, 0.91) in comparison with the PDE5i group. Inverse associations between TS and prostate cancer were observed in a majority of subgroup analyses, although in both comparisons estimates generally attenuated with increasing time following initial exposure. Amongst TS users, duration of exposure was not associated with prostate cancer. Conclusion: In this study, men who received TS did not have a higher rate of prostate cancer compared with the unexposed or PDE5i comparison groups. The inverse association between TS and prostate cancer could be the result of residual confounding, contraindication bias, or undefined biologic effect. Citation Format: Michael B. Cook, Daniel C.

Teenage Pregnancies and Births in Germany: Patterns and Developments

Field: Social Sciences (Social Sciences)

We study the development of teenage fertility in East and West Germany using data from the German Socioeconomic Panel (SOEP) and from the German Mikrozensus. Following the international literature we derive hypotheses on the patterns of teenage fertility and test whether they are relevant in the German case. We find that teenage fertility is associated with teenage age and education, with the income of the teenager's family, with migration status, residence in East Germany, and aggregate unemployment. Our evidence supports countercyclical teenage fertility.
Improving image quality in intensity-interferometric spectral-domain optical coherence tomography

Field: Physics and Astronomy (Physical Sciences)

Intensity-interferometric spectral-domain optical coherence tomography (I-SD-OCT), devised recently as a classical analog of quantum OCT, enables axially scanless cross-sectional imaging with an immunity to group-velocity dispersion and a factor-of- resolution improvement. However, unwanted artifacts inevitably emerge in the resultant image. In this paper, it is demonstrated theoretically and experimentally that such artifacts can be reduced without any difficulty by means of either a mechanical displacement of the detector for capturing spectral intensity patterns or a numerical displacement of the spectral intensity patterns stored in a computer. Furthermore, it is proved that the I-SD-OCT signal can be extracted from the conventional SD-OCT setup under a certain condition. These two features serve to improve the image quality in I-SD-OCT.
Crassaostrea gigas Oyster Shell Extract Inhibits Lipogenesis via Suppression of Serine Palmitoyltransferase

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Oysters are widely consumed seafood, but their shells impose a serious environmental problem. To extend the utilization of oyster shell waste, we investigated the biological role of oyster shell extract. In this study, we verified that the ethanol extract of oyster shell (EOS) contains taurine and betaine, the major components of oyster body. EOS downregulated transcription of Sptlc1 and Sptlc2 mRNA, the subunits of serine palmitoyltransferase (SPT). Suppression of SPT subunits reduced sphinganine and sphingomyelin by inhibiting de novo sphingolipid biosynthesis. Inhibition of sphingomyelin biosynthesis resulted in downregulation of lipogenic gene expression such as ACC, FAS, SCD1, and DGAT2. Consistent with inhibition of lipogenesis, cellular triglyceride levels were diminished by EOS, but cholesterol levels were not altered. Taken together, these results suggest that EOS has a lipid-lowering effect and could be applied as either a therapeutic or preventive measure for metabolic dysfunction.
Small flame ignitability and flammability behavior of upholstered furniture materials

Field: Engineering (Physical Sciences)

Identical upholstered furniture fabric and padding specimens were exposed to four increasingly severe small flaming ignition sources and to a radiant source.The small ignition sources were partly patterned after the Bunsen burner tests of BS 5852 Part 2.For the radiant source, the Cone Calorimeter was used, and specimens were exposed to irradiances of 10 and 15 kW/m 2 .A wide range of ignition properties was found, depending on both the cover fabric and padding.The relationship between Cone Calorimeter and small scale ignition tests was generally as follows:Specimens, which, when exposed in the Cone Calorimeter at 15 kW/m 2 irradiance, reached a heat release rate of 50 kW/m 2 in less than 60 seconds generally were ignited by the two smaller sources used.Conversely, specimens which reached this heat release rate in longer times generally had greater small flame ignition resistance.Suggestions are also made for further improvements in the design of small scale flaming ignition and Cone Calorimeter tests for specimens combining a upholstery fabric and a padding.The major such improvement would be to break the char in such test, which probably often breaks in real life experiments but in small scale experiments may protect the padding material.
Development and validation of a liquid chromatography tandem mass spectrometry method for the measurement of urinary catecholamines in diagnosis of pheochromocytoma

Field: Medicine (Health Sciences)

Abstract The measurement of catecholamines in human body fluids is requested frequently for the differential diagnosis and monitoring of pheochromocytoma. The methods in most clinical laboratories focus on high‐performance liquid chromatography coupled with electrochemical detection, which suffers from high background noise, low sensitivity, and poor separation. We reported and developed a robust high‐throughput liquid chromatography tandem mass spectrometry method in routine clinical laboratories for the measurement of urinary catecholamines for diagnosis of pheochromocytoma. The method was validated for consistent linearity, good recovery (88–112%), excellent stability and low carryover. Intra‐ and inter‐assay precision values for catecholamines were all below 3.35 and 4.83% respectively. Dilution linearity was investigated with satisfactory linearly dependent coefficients ( r > 0.9988). The reference intervals were obtained from 310 results derived from patients in which the diagnosis of pheochromocytoma was excluded. This method was successfully used in our laboratory. The clinical characteristics of patients have been explored with satisfactory sensitivity and specificity. Therefore, we have developed a reliable assay for the liquid chromatography tandem mass spectrometry measurement of catecholamines in a routine clinical laboratory. The assay requires a small volume of urine, and all analytes are measured simultaneously. The assay is rapid and reliable to be executed, offering the potential for routine clinical laboratories.
Corporate disclosure, transparency and firms cash holdings: Evidence from the Emerging capital market of Ghana

Field: Economics, Econometrics and Finance (Social Sciences)

The paper documents the monitoring effect of corporate disclosure and transparency on cash holdings on the Ghana Stock Exchange (GSE). The paper employs the Fama and French (1998) valuation model by relating firm level variables to firm value with panel data covering a period from 2002 to 2007 for 23 firms. It builds further on the agency theory and its relevance to emerging markets. We find that the relationship between corporate disclosure, transparency and cash holdings is economically significant and inversely related. We provide that a 1% increase in the composite disclosure and transparency index decreases cash holding by 0.0338 with the market also discounting the value of such firms by 0.0522. Additionally, we provide that firm size, profitability, financial leverage and investment needs are economically significant determinants of cash holdings. The sample refers to only Ghana and the extent of generation of the findings could be affected. We argue that further research should be carried out using other country data to confirm or contradict our findings. The paper includes implications for the management of cash resources on the GSE and builds on the mechanism of aligning the interest of shareholders with managers. It further provides implications for the development of the capital market in Ghana and argues that further research should be carried out using other country data to confirm or contradict our findings Key words: Corporate disclosure, transparency, cash holdings, emerging market, Ghana.
Full-duplex cooperative cognitive radio networks

Field: Computer Science (Physical Sciences)

We study the impact of a full-duplex secondary node on a cognitive cooperative network with Multipacket Reception (MPR) capabilities at the receivers. Motivated by recent schemes that make full-duplex communication feasible, we study a model with one primary and one secondary transmitter-receiver pair, where the secondary transmitter is able to relay primary unsuccessful packets. Cooperation between primary and secondary users has been previously shown to be beneficial for the primary and the secondary users in terms of stable throughput. Our model assumes an imperfect full-duplex secondary node that can transmit and receive simultaneously, cancelling self-interference to a certain extent. Furthermore, we assume that the secondary transmitter chooses between cooperating with the primary user and transmitting secondary packets probabilistically according to some optimized probabilities that depend on both the channels in the network and the state of the primary user. We determine these probabilities by formulating a constrained optimization problem with the secondary throughput as the objective function and the stability of the primary queues as constraints. Using the dominant system approach, we show that the optimization problem has a quasi-concave structure, to which the optimal solution can be easily found. Using Numerical results, we characterize the cases where the full-duplex capability is beneficial to the system, namely, we show that the full-duplex secondary node greatly increases both the secondary throughput and the primary maximum stable throughput in channels with receivers that have strong MPR capability.
[Selenium correction of male subfertility].

Field: Medicine (Health Sciences)

To study the effect of selenium in subfertile men, three groups of men were studied. Group 1--31 subfertile men living in healthy environment, group 2--25 subfertile men exposed for a long time to low doses of gas containing hydrogen sulfide, group 3--control 43 fertile men. Men of groups 1 and 2 received 3 courses of selenium (3.5 microg/kg/day for 30 days). Before the treatment and after each course ejaculate fertility was assessed by spermogram, enzyme activity of alpha-amylase (EC 3.2.1.1) and lactate dehydrogenase (EC 1.1.1.27), concentrations of prostatic acid phosphatase, sperm-specific inhibitor tripsin and prostate-specific antigen. Selenium proved effective, the response being higher in group 2 than in group 1. The causes of this difference are discussed. It is thought possible to use selenium for correction of some subfertility forms in men.
Six Sigma implementation in a manufacturing unit - a case study

Field: Decision Sciences (Social Sciences)

The Six Sigma approach has been increasingly adopted in the manufacturing sector in order to make the process robust to quality variations, thereby, improving the quality and performance. In any manufacturing industry, Shainin Six Sigma methodology is highly adopted because of lesser data collection required for the study. Six Sigma improves the process performance of the critical operational process, leading to better utilisation of resources, decrease in variations and maintaining consistent quality of the process output. The DMAIC approach has been followed here to solve an underlying problem of reducing process variation and the associated high defect rate. This paper describes an application of Six Sigma define, measure, analyse, improve and control (DMAIC) methodology in a manufacturing unit, which provides a framework to identify, quantify and eliminate sources of variation in an operational process to improve the quality. The current investigation focuses on using DMAIC methodology to reduce the rejections in the pasting process during product X manufacturing, resulting in a saving of Rs. 3.96 lakhs per annum
An Antipyretic Guideline for Pediatric Patients in an Urgent Care Setting

Field: Health Professions (Health Sciences)

Fever is a common chief complaint and concern of parents in the pediatric population. Urgent care clinics commonly treat pediatric patients with fever and must also deal with an inappropriate parental knowledge base (Martins & Abecasis, 2016; Purssell, 2008; Wallenstein et al., 2012; Walsh, Edwards, & Fraser, 2007; Walsh, Edwards, & Fraser, 2008). The purpose of this evidence-based project was to design and implement a pediatric antipyretic guideline and fever facts sheet to increase recognition and the use of appropriate antipyretic treatments in the clinical and home settings. This project was implemented using the ACE Star Model of Knowledge Transformation at the Urgent Care Wailea Makena (UCWM), using a pretest– posttest design to evaluate the innovations’ impact on the outcomes. The practice change was an implementation of a protocol algorithm and an educational handout to address pediatric fever, which did not previously exist. Both innovations assured consistent evidence-based information would be followed and discussed with the parents of the pediatric patients in the clinic at the time of care. Historical data, from 2015 and 2016, was compared to post-implementation data collected from July 2017 through October 2017. Data elements were taken from charts, then compared and analyzed. The results suggest that the antipyretic guideline and fever facts sheet were successful in improving the recognition and appropriate treatment of fever in the pediatric patient aged six months to six years in an urgent care setting. It also suggests that health care team members and parents/caregivers of pediatric patients are receptive to improving and updating their knowledge of pediatric fever treatments.
Women consuming oral contraceptives containing cyproterone acetate and ethinylestradiol show a higher risk of thyroid cancer than nonusers

Field: Medicine (Health Sciences)

This study explored whether the risk of thyroid cancer in Asian women is associated with consumption of oral contraceptives (Diane-35). We conducted a population-based, retrospective cohort study using the Taiwan National Health Insurance Research Database. From the database, 9865 women aged 18 to 65 years who were prescribed Diane-35 between 2000 and 2012 were included in the Diane-35 group, and 39,460 women who were not prescribed Diane-35 were included in the comparison group and were frequency-matched by age and index year. Both groups were followed until 2013 to calculate the incidence of thyroid cancer. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using Cox proportional hazard model. The median (standard deviation) follow-up duration was 7.08 (3.63) and 7.04 (3.64) years in the Diane-35 and the comparison group, respectively. The incidence of thyroid cancer was 1.80-fold higher in the Diane-35 group than in the comparison group (2.72 vs 1.51 per 10,000 person-years). The cumulative incidence of thyroid cancer was significantly higher in the Diane-35 group than in the comparison group (log-rank test, P = .03). An elevated hazard ratio of thyroid cancer was observed in the Diane-35 group than in the comparison group (HR: 1.91, 95% CI: 1.10–3.30). In subgroup analysis, patients aged 30 to 39 years showed a higher hazard ratio of developing thyroid cancer after consuming Diane-35 than those in the comparison group (HR: 5.58, 95% CI: 1.84–16.91). The study provides evidence that women aged 30 to 39 years consuming Diane-35 are at increased risk of thyroid cancer. Nevertheless, a larger population with a longer follow-up may be necessary to confirm causality.
