Relaxation of the sodium atom in the 4D level by collisions with noble gases. II. Theoretical aspects

2014 In previous papers [1-3] we have reported experimental measurements of the relaxation rates of the k-multipole moments in the 4D level of sodium and the 3S-4D optical coherence. In the present paper we compare the experimental values with those obtained theoretically for different types of potentials. We show that the Van der Waals C6R -6 interaction is not sufficiently anisotropic to describe the relaxation of the k multipole moments. For Ar, Kr and Xe, much better results are obtained by taking into account the next term C8R-8 in the expansion of the long-range interaction. The potentials of Pascale and Vandeplanque [4] give very good results for helium. The results are also satisfactory for Ar, Kr and Xe, but the agreement could still be improved.

Effective anti-tuberculosis therapy correlates with plasma small RNA.

Small RNA (smRNA) is a diverse family of translation regulation molecules, which includes microRNA (miRNA). Changes in miRNA have been reported in association with respiratory disease [1] and in mycobacterial infection [2]. Studies have measured concentrations of miRNA pooled from multiple subjects with active tuberculosis (TB) disease compared with latently infected individuals and healthy controls [3]. However, this approach cannot assess variation between individuals, nor does it describe changes that might occur with treatment, both of which may be helpful in characterising and predicting patient outcome.
Tadalafil once daily improves ejaculatory function, erectile function, and sexual satisfaction in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia and erectile dysfunction: results from a randomized, placebo- and tamsulosin-controlled, 12-week double-blind study.

INTRODUCTION
Tadalafil, a long-acting phosphodiesterase type 5 inhibitor, is approved for treating signs and symptoms of benign prostatic hyperplasia (BPH) and erectile dysfunction (ED); tamsulosin, an alpha-blocker, is approved for treating signs and symptoms of BPH.


AIM
To determine the effects of tadalafil or tamsulosin on sexual function, including ejaculation and orgasm, satisfaction, and erectile function, in sexually active men with ED and lower urinary tract symptoms suggestive of BPH (LUTS/BPH).


METHODS
A randomized, double-blind, placebo-controlled study of tadalafil 5 mg once daily for 12 weeks in men with LUTS/BPH; tamsulosin 0.4 mg once daily was an active control.


MAIN OUTCOME MEASURES
The International Index of Erectile Function (IIEF) questionnaire was administered at baseline and 4, 8, and 12 weeks. Analysis of orgasm and ejaculation was post hoc based on the IIEF-Orgasmic Function (OF) domain (IIEF-Q9 [ejaculatory frequency] and Q10 [orgasmic frequency]). Other measures included IIEF-Intercourse Satisfaction (IS), Overall Satisfaction (OS), and Erectile Function (EF) domains. Changes from baseline to 12 weeks (or last observation) vs. placebo were analyzed using analysis of covariance. Higher IIEF scores indicate better functioning.


RESULTS
Of 511 study participants, 310 (60.7%) had ED and were sexually active. The IIEF-OF increased significantly through 12 weeks with tadalafil vs. placebo (P = 0.048), as did IIEF-Q9 (P = 0.045) but not IIEF-Q10 (P = 0.100). Compared with placebo, IIEF-OF, Q9, and Q10 decreased significantly with tamsulosin (all P < 0.05). The IIEF-IS and OS increased significantly at end point with tadalafil (both P < 0.001); for tamsulosin, change was not significant for IS, while OS decreased significantly (P = 0.009). The IIEF-EF domain increased significantly vs. placebo with tadalafil (P < 0.001) but not tamsulosin (P = 0.699).


CONCLUSIONS
Tadalafil 5 mg once daily significantly improved ejaculation and orgasm, intercourse and overall satisfaction, and erectile function. Men receiving tamsulosin 0.4 mg once daily experienced a decrease in both ejaculatory/orgasmic frequency and overall satisfaction vs. placebo, with no significant effect on erectile function.
ICPR2018 Contest on Object Detection in Aerial Images (ODAI-18)

Object detection in aerial images plays a significant role in intelligent interpretation of aerial images. Hence many effective methods, especially the new-generation data-driven methods, have been developed for this task. Here, we hold the ODAI, a new contest that focused on object detection in aerial images, based on a new large-scale aerial image dataset called DOTA [1]. This contest contains over 3000 large-size images ($4k\times 4k$ pixels), which cover 211,581 instances divided into 15 categories. Each instance is labeled by an arbitrary (8 d.o.f.) quadrilateral. Besides, we propose two tasks for this contest, named object detection with the horizontal bounding box (OD-HBB) and object detection with the oriented bounding box (OD-OBB). The contest was opened on February 7, 2018, and ended on April 30, 2018. A website is open to the public, which provides links to download data and evaluation server. We have totally received 60 registrations. There are 8 teams that have successfully submitted results on the OD-HBB task with the top mAP as 0.719, and 9 teams that have successfully submitted results on the OD-OBB task with the top mAP as 0.705. Through the contest, we hope to draw extensive attention from a wide range of communities and call for more future research and efforts for the task of object detection in aerial images.
Hybrid fuzzy-genetic algorithm approach for crew grouping

Crew grouping is an important problem and formulating a good solution always involves many challenges. For example, grouping soldiers intelligently to tank combat units, we should take into consideration the combined technical proficiency of the soldiers, the amount of military training, the units from which the soldiers come, their service age, personal background, etc. In this paper, we propose a hybrid fuzzy-genetic algorithm (FGA) approach to solve the crew grouping problem. Fuzzy logic based controllers are applied to fine-tune dynamically the crossover and mutation probability in the genetic algorithms, in an attempt to improve the algorithm performance. The FGA approach is compared with the standard genetic algorithm (SGA). Empirical results clearly demonstrates that while the SGA approach gives satisfactory solutions for the problem, the FGA method usually performs significantly better.
A Novel Wireless Power Transfer System With Double Intermediate Resonant Coils

A novel wireless power transfer (WPT) system with double intermediate resonators is proposed. In addition to the power and load coils, this WPT system has four self-resonators: 1) a sending resonator; 2) a receiving resonator; and 3) two intermediate resonators. For optimal design, this WPT system is analyzed using an equivalent circuit model. In particular, a tuning scheme for coupling coefficients is proposed to determine optimal positions of the power and load self-resonators for maximizing the power transfer efficiency. The experiments show that the electric power can be wirelessly transferred to the receiving coil located at a distance of more than four times the resonator diameter away from the sending coil. The measured transfer efficiency of this WPT system is above 70%.
Manipulation through Bribes

We consider allocation rules that choose both an outcome and transfers, based on the agents’ reported valuations of the outcomes. Under a given allocation rule, a bribing situation exists when agent j could pay agent i to misreport his valuations, resulting in a net gain to both agents. A rule is bribe-proof if such opportunities never arise. The central result is that when a bribe-proof rule is used, the resulting payoff to any one agent is a continuous function of any other agent’s reported valuations. We then show that on connected domains of valuation functions, if either the set of outcomes is finite or each agent’s set of admissible valuations is smoothly connected, then an agent’s payoff is a constant function of other agents’ reported valuations. Finally, under the additional assumption of a standard domainrichness condition, we show that a bribe-proof rule must be a constant function. The results apply to a very broad class of economies.
Utilization and 1-Year Mortality for Transcatheter Aortic Valve Replacement and Surgical Aortic Valve Replacement in New York Patients With Aortic Stenosis: 2011 to 2012.

OBJECTIVES
The purpose of this study was to investigate changes in the use of transcatheter aortic valve replacement (TAVR) relative to surgical aortic valve replacement (SAVR) and to examine relative 1-year TAVR and SAVR outcomes in 2011 to 2012 in a population-based setting.


BACKGROUND
TAVR has become a popular option for patients with severe aortic stenosis, particularly for higher-risk patients.


METHODS
New York's Cardiac Surgery Reporting System was used to identify TAVR and SAVR volumes and to propensity match TAVR and SAVR patients using numerous patient risk factors contained in the registry to compare 1-year mortality rates. Mortality rates were also compared for different levels of patient risk.


RESULTS
The total number of aortic valve replacement patients increased from 2,291 in 2011 to 2,899 in 2012, an increase of 27%. The volume of SAVR patients increased by 7.1% from 1,994 to 2,135 and the volume of TAVR patients increased 157% from 297 to 764. The percentage of SAVR patients that were at higher risk (≥3% New York State [NYS] score, equivalent to a Society of Thoracic Surgeons score of about 8%) decreased from 27% to 23%, and the percentage of TAVR patients that were at higher risk decreased from 83% to 76%. There was no significant difference in 1-year mortality between TAVR and SAVR patients (15.6% vs. 13.1%; hazard ratio [HR]: 1.30 [95% confidence interval (CI): 0.89 to 1.92]). There were no differences among patients with NYS score <3% (12.5% vs. 10.2%; HR: 1.42 [95% CI: 0.68 to 2.97]) or among patients with NYS score ≥3% (17.1% vs. 14.5%; HR: 1.27 [95% CI: 0.81 to 1.98]).


CONCLUSIONS
TAVR has assumed a much larger share of all aortic valve replacements for severe aortic stenosis, and the average level of pre-procedural risk has decreased substantially. There are no differences between 1-year mortality rates for TAVR and SAVR patients.
Evaluation of the web-based Diabetes Interactive Education Programme (DIEP) for patients with type 2 diabetes.

OBJECTIVE
The objective in this study was to evaluate a web-based type 2 diabetes self-management education programme aimed at improving knowledge, encouraging active patient participation and providing supportive self-management tools.


METHODS
(1) An effect evaluation was conducted using a randomized controlled trial with a pre-test and post-test design (n=99) and a knowledge questionnaire. (2) A user evaluation was conducted using an online questionnaire (n=564) and one-on-one interviews (n=11) to examine the perceived quality, use of functionalities and use of the programme as a supportive tool in education.


RESULTS
The effect evaluation showed a significant intervention effect (p<0.01) on knowledge. The user evaluation showed high satisfaction with the programme's content, credibility and user-friendliness. However, functionalities and self-management tools were used by less than half of the participants.


CONCLUSION
The programme can improve knowledge, but it is not fully used as intended. A more optimal use of the programme is necessary for higher efficacy.


PRACTICE IMPLICATIONS
The use of mostly spoken text instead of written text was highly appreciated and could be used more often for educational websites. Furthermore, health care practitioners need support in implementing new educational programmes during consultations.
Creation of a neovagina by Davydov's laparoscopic modified technique in patients with Rokitansky syndrome.

OBJECTIVE
The purpose of this study was to assess anatomic and functional results after the laparoscopic Davydov procedure for the creation of a neovagina in Rokitansky syndrome.


STUDY DESIGN
Thirty patients with Rokitansky syndrome underwent the laparoscopic Davydov technique from June 2005-August 2008. Mean follow-up time lasted 30 months (range, 6-44 months) and included clinical examinations and evaluation of the quality of sexual intercourse; vaginoscopy, Schiller's test, and neovaginal biopsies were performed after 6 and 12 months. Functional results were assessed with the use of Rosen's Female Sexual Function Index and were compared with age-matched normal control subjects.


RESULTS
No perioperative complications occurred. At 6 months, anatomic success was achieved in 97% of the patients (n = 29); functional success and optimal results for the Female Sexual Function Index questionnaire were obtained in 96% of patients. Vaginoscopy and biopsy results showed a normal iodine-positive vaginal epithelium.


CONCLUSION
The Davydov technique seems to be a safe and effective treatment for vaginal agenesis in patients with Rokitansky syndrome.
Efficacy and safety of canagliflozin monotherapy in subjects with type 2 diabetes mellitus inadequately controlled with diet and exercise

AIMS
Canagliflozin is a sodium glucose co-transporter 2 inhibitor in development for type 2 diabetes mellitus (T2DM). The efficacy and safety of canagliflozin were evaluated in subjects with T2DM inadequately controlled with diet and exercise.


METHODS
In this 26-week, randomized, double-blind, placebo-controlled, phase 3 trial, subjects (N = 584) received canagliflozin 100 or 300 mg or placebo once daily. Primary endpoint was the change from baseline in haemoglobin A1c (HbA1c) at week 26. Secondary endpoints included the proportion of subjects achieving HbA1c < 7.0%; change from baseline in fasting plasma glucose (FPG), 2-h postprandial glucose (PPG) and systolic blood pressure (BP); and percent change in body weight, high-density lipoprotein cholesterol (HDL-C) and triglycerides. Adverse events (AEs) were recorded throughout the study.


RESULTS
At week 26, HbA1c was significantly reduced from baseline with canagliflozin 100 and 300 mg compared with placebo (-0.77, -1.03 and 0.14%, respectively; p < 0.001 for both). Both canagliflozin doses significantly decreased FPG, 2-h PPG, body weight and systolic BP (p < 0.001 for all), and increased HDL-C compared with placebo (p < 0.01 for both). Overall incidences of AEs were modestly higher with canagliflozin versus placebo; rates of serious AEs and AE-related discontinuations were low and similar across groups. Incidences of genital mycotic infections, urinary tract infections and osmotic diuresis-related AEs were higher with canagliflozin; these led to few discontinuations. The incidence of hypoglycaemia was low across groups.


CONCLUSION
Canagliflozin treatment improved glycaemic control, reduced body weight and was generally well tolerated in subjects with T2DM inadequately controlled with diet and exercise.
Biosynthesis of Citric Acid from Glycerol by Acetate Mutants of Yarrowia lipolytica in Fed-Batch Fermentation

Pure and crude glycerol from biodiesel production have been used as substrates for citric acid production by acetate-negative mutants of Yarrowia lipolytica in fed-batch fermentation. Both the final concentration and the yield of the product were the highest when Y. lipolytica Wratislavia AWG7 strain was used in the culture with pure or crude glycerol. With a medium containing 200 g/L of glycerol, production reached a maximum of citric acid of 139 g/L after 120 h. This high yield of the product (up to 0.69 g of citric acid per gram of glycerol consumed) was achieved with both pure and crude glycerol. Lower yield of citric acid in the culture with Y. lipolytica Wratislavia K1 strain (about 0.45 g/g) resulted from increased erythritol concentrations (up to 40 g/L), accumulated simultaneously with the citric acid. The concentration of isocitric acid, a by-product in this fermentation, was very low, in the range from 2.6 to 4.6 g/L.
Relationship between visual-motor integration and handwriting skills of children in kindergarten: a modified replication study.

OBJECTIVE
The purpose of this study was to examine the relationship of performance on the Developmental Test of Visual-Motor Integration (VMI; Beery, 1997) to handwriting legibility in children attending kindergarten. The relationship of using lined versus unlined paper on letter legibility, based on a modified version of the Scale of Children's Readiness in PrinTing (Modified SCRIPT; Weil & Cunningham Amundson, 1994) was also investigated.


METHOD
Fifty-four typically developing kindergarten students were administered the VMI; 30 students completed the Modified SCRIPT with unlined paper, 24 students completed the Modified SCRIPT with lined paper. Students were assessed in the first quarter of the kindergarten school year and scores were analyzed using correlational and nonparametric statistical measures.


RESULTS
Strong positive relationships were found between VMI assessment scores and student's ability to legibly copy letterforms. Students who could copy the first nine forms on the VMI performed significantly better than students who could not correctly copy the first nine VMI forms on both versions of the Modified SCRIPT.


CONCLUSION
Visual-motor integration skills were shown to be related to the ability to copy letters legibly. These findings support the research of Weil and Cunningham Amundson. Findings from this study also support the conclusion that there is no significant difference in letter writing legibility between students who use paper with or without lines.

No effect of risedronate on femoral periprosthetic bone loss following total hip arthroplasty

BACKGROUND AND PURPOSE
We have previously shown that during the first 2 years after total hip arthroplasty (THA), periprosthetic bone resorption can be prevented by 6 months of risedronate therapy. This follow-up study investigated this effect at 4 years.


PATIENTS AND METHODS
A single-center, double-blind, randomized placebo-controlled trial was carried out from 2006 to 2010 in 73 patients with osteoarthritis of the hip who were scheduled to undergo THA. The patients were randomly assigned to receive either 35 mg risedronate or placebo orally, once a week, for 6 months postoperatively. The primary outcome was the percentage change in bone mineral density (BMD) in Gruen zones 1 and 7 in the proximal part of the femur at follow-up. Secondary outcomes included migration of the femoral stem and clinical outcome scores.


RESULTS
61 of the 73 patients participated in this 4-year (3.9- to 4.1-year) follow-up study. BMD was similar in the risedronate group (n = 30) and the placebo group (n = 31). The mean difference was -1.8% in zone 1 and 0.5% in zone 7. Migration of the femoral stem, the clinical outcome, and the frequency of adverse events were similar in the 2 groups.


INTERPRETATION
Although risedronate prevents periprosthetic bone loss postoperatively, a decrease in periprosthetic BMD accelerates when therapy is discontinued, and no effect is seen at 4 years. We do not recommend the use of risedronate following THA for osteoarthritis of the hip.
Assessment challenges in open learning: Way-finding, fork in the road, or end of the line?

Growing global commitments to open learning through the use of Open Educational Resources (OERs) are accompanied by concerns over what “to do” with that learning when learners present it to traditional institutions for assessment and accreditation. This paper proposes that established RPL (recognizing prior learning) protocols, in place at many institutions worldwide, can offer a pedagogically sound framework that supports the spirit of open learning and respects the diversity of learners’ efforts.
Reconstructing human contributions to accidents: the new view on error and performance.

PROBLEM
How can human contributions to accidents be reconstructed? Investigators can easily take the position a of retrospective outsider, looking back on a sequence of events that seems to lead to an inevitable outcome, and pointing out where people went wrong. This does not explain much, however, and may not help prevent recurrence.


METHOD AND RESULTS
This paper examines how investigators can reconstruct the role that people contribute to accidents in light of what has recently become known as the new view of human error. The commitment of the new view is to move controversial human assessments and actions back into the flow of events of which they were part and which helped bring them forth, to see why assessments and actions made sense to people at the time. The second half of the paper addresses one way in which investigators can begin to reconstruct people's unfolding mindsets.


IMPACT ON INDUSTRY
In an era where a large portion of accidents are attributed to human error, it is critical to understand why people did what they did, rather than judging them for not doing what we now know they should have done. This paper helps investigators avoid the traps of hindsight by presenting a method with which investigators can begin to see how people's actions and assessments actually made sense at the time.
Individualized anticoagulation with dermatan sulphate for haemodialysis in chronic renal failure.

BACKGROUND
Dermatan sulphate (DS) is a selective thrombin inhibitor with antithrombotic properties and low bleeding potential. In preliminary studies it was reported to be effective for preventing clot formation in the haemodialysis circuit.


METHODS
Ten patients on maintenance haemodialysis for chronic renal failure underwent three consecutive investigation phases. In phase 1 (individual dose titration), repeated dialyses were performed with increasing doses of DS until successful dialysis was obtained in two sessions at the same dose. In phase 2, individualized DS doses were validated by a randomized crossover comparison with the individual heparin dose of each patient. In phase 3, each patient underwent 24 consecutive dialyses with DS over 8 weeks. Successful dialysis was defined as completion of the procedure without visible clot formation in the bubble traps and lines or a greater than 20% decrease in dialyser capacity. Dialysis efficiency (decrease in serum urea and creatinine, Kt/V), APTT prolongation, bleeding time, and DS plasma concentrations were also assessed.


RESULTS
Phase 1: successful dialysis was achieved in nine patients with 4 mg/kg DS as a predialysis intravenous bolus followed by continuous infusion of 0.65 mg/kg/h. One patient required 5 mg/kg plus 1.3 mg/kg/h. Phase 2: no statistically significant differences were found between DS and heparin in any of the investigated variables. Residual dialyser capacity and dialysis efficiency indexes indicated equivalent efficacy. Phase 3: residual dialyser capacity and dialysis efficiency did not change with time. There was no accumulation of DS in plasma. No bleeding or thrombocytopenia were observed.


CONCLUSIONS
The dose of DS can be individually titrated to suppress clot formation during haemodialysis as efficiently as with individualized heparin. Such an individualized DS regimen maintains its anticoagulant efficacy and is safe in prolonged use.
