Published: September 2020

This study aims to obtain empirical evidence about the influence of company commissioners, profitability, leverage and company size along with tax avoidance as a moderating variable on the timeliness of financial statement submission in manufacturing companies in Indonesia. The population in this study is manufacturing companies listed on the Indonesia Stock Exchange (IDX) during 2014-2018 with a total of 41 companies.
The results of this study indicate that company commissioners, profitability and leverage have a significant effect on tax avoidance, while company size has no significant effect on tax avoidance as a mediating variable. Then the results of the tax avoidance intervention on the timeliness of financial reporting do not only show significant results but also do not mediate in character.

Abstract
Background: Glucose variability has been associated with cardiovascular outcomes in type 2 diabetes, however, the interplay between glucose variability, empagliflozin and cardiovascular death has not been explored. In the EMPA-REG OUTCOME trial, empagliflozin reduced the risk of cardiovascular death by 38%. We explore post-hoc the association between HbA1c variability and cardiovascular death, and the potential mediating effects of HbA1c variability on empagliflozin’s cardiovascular death reductions.Methods: In total, 7,020 patients with type 2 diabetes and established cardiovascular disease received placebo, empagliflozin 10 mg or 25 mg. We defined within-patient HbA1c variability as standard deviation, coefficient of variation and range of HbA1c measurements (%) post-baseline. First, we compared HbA1c variability until week 28 and 52 by Wilcoxon tests. We explored the association between cardiovascular death and HbA1c variability in placebo and pooled empagliflozin arms separately with landmark analyses at week 28 and 52, and additionally with HbA1c variability as a time-dependent co-variate. We used Cox regression models adjusted for baseline risk factors including changes in HbA1c from baseline to week 12, and the interaction term HbA1c variability* treatment.Results: HbA1c variability was lower with empagliflozin compared to placebo. In all Cox analyses, high HbA1c variability increased the risk for cardiovascular death in both treatment arms with no interaction with treatment: e.g.an increase in HbA1c variability of one unit for the standard deviation at week 28 was associated with a subsequent increased risk of CV death with HRs of 1.97 (95% CI 1.36, 2.84) and 1.53 (1.01, 2.31) in the placebo and empagliflozin groups, separately, interaction p-value 0.3615.Conclusions: HbA1c variability was reduced by empagliflozin and high values of HbA1c variability were associated with an increased risk of cardiovascular death. Empagliflozin’s reduction in cardiovascular death did not appear to be mediated by reductions in HbA1c variability.ClinicalTrials.gov number, NCT01131676

Abstract
Background: Pulmonary artery hypertension (PAH) in the setting of end-stage renal disease (ESRD) has important prognostic and therapeutic consequences. We estimated the prevalence of PAH among patients with ESRD treated with automated peritoneal dialysis (APD), investigated the effect of different variables and compared pulmonary artery pressure and cardiac function at the beginning and end of the study. Methods: The study that started on 2015 and extended till 2020. Thirty-one ESRD patients on APD were recruited after fulfilling inclusion criteria. Blood samples were collected from all patients for the biochemical and hematological data at the beginning of the study and every month and at the study termination. Total body water (TBW) and extracellular water (ECW) were calculated using Watson’s and Bird’s calculation methods. All patients were followed-up monthly by cardiologist for an echocardiographic examination. Cox regression analysis was used to assess the relation between different variables and PAH.Results: The mean age of the study population (n=31) was 51.23±15.24 years. PAH was found in 24.2% of the patients. Mean systolic pulmonary artery pressure (sPAP) and mean pulmonary artery pressure (mPAP) were significantly higher in the APD patients at study initiation than at the end of the study (40.75 + 10.61 vs 23.55 + 9.20 and 29.66 + 11.35 vs 18.24 + 6.75 mmHg respectively, p = 0.001). The median ejection fraction was significantly lower in patients with PAH at zero point than at study termination [31% (27-34) vs 50% (46-52), p = 0.002]. Hypervolemia decreased significantly at the end of study (p <0.001) and correlated positively with the PAP (r = 0.371 and r = 0.369), p = 0.002). sPAP correlated with left ventricular mass index, hemoglobin level, and duration on APD.Conclusions: Long term PD (> 2 years) seemed to decrease pulmonary artery pressure, right atrial pressure and improve left ventricular ejection fraction (LVEF). Risk factors for PAH in ESRD were hypervolemia, abnormal ECHO findings and low hemoglobin levels. Clinical and echocardiographic abnormalities and complications are not uncommon among ESRD patients with PAH. Identification of those patients on and transthoracic echocardiography may warrant further attention to treatment with APD.

Published: September 2020

Abstract
﻿Background: β-TCP is a synthetic grafting material (alloplasts)that can be used as allografts and xenografts in peridontal periodontal infra-bony defect. However, it is important to compare this material outcomes in such treatments when comparted to others Therefore, the aim of this review is to evaluate the effectiveness of β-TCP in the regeneration of periodontal infra-bony defect. Methods: Three electronic databases (Cochrane, Pubmed, Embase) were searched up to March 2020. The inclusion criteria consist of regeneration of periodontal infra-bony defect via implementation of β-TCP in combination with other bone graft materials. Outcomes consisted of pocket depth reduction, clinical attachment level gain and bone fill. Results: Five studies were included according to inclusion criteria. β-TCP found to be superior than debridement alone while it shown comparable result to other bone grafts materials in term of pocket depth reduction, clinical attachment level gain and bone fill. the outcomes of the regenerative procedures of periodontal infra-bony defect with the use of β-TCP in combination with other growth factors seems to be superior than alone. Conclusion: β-TCP seems to be a promising material to be used in periodontal infra-bony defect regeneration. However, randomized clinical trials with larger sample size and more controlled study design are needed to support the findings.
Controllable spin switching in a single-molecule magnetic tunneling junction
Authors: Zhang Zhengzhong , Wang Ya , Wang Haiou , Liu Hao , Dong Liming 
Published: September 2020

Abstract
A new type of spin-current filter is proposed that consists of a single molecule magnet (SMM) coupled to two normal metal electrodes. It is shown that this tunneling junction can generate a highly spin-polarized current, whose spin polarization can be switched by means of magnetic fields and gate voltages applied to the SMM. This spin switching in the SMM tunnel junction arises from spin-selective single electron resonant tunneling via the lowest unoccupied molecular orbit of the SMM. The electron current spectrum is still spin polarized in the absence of an external magnetic field, which can help to judge whether the molecule’s spin state has reached the ground-state doublet |± S > . This device can be realized with current technologies and may have practical use in spintronics and quantum information.

Published: September 2020

Abstract
Background: Enhancing postoperative recovery of the donor is important to encourage living kidney donation. We investigated the effects of anesthetic agents (intravenous [IV] propofol versus inhaled [IH] sevoflurane) on the quality of early recovery of healthy living kidney donors after hand-assisted laparoscopic nephrectomy (HALN) under analgesic intrathecal morphine injection. Methods: This single-center, prospective randomized controlled study enrolled 80 living donors undergoing HALN from October 2019 to June 2020 at Seoul St. Mary’s Hospital. Donors were randomly assigned to the IV propofol group or IH sevoflurane group. To measure the quality of recovery, we used the Korean version of the Quality of Recovery-40 questionnaire (QoR-40K) on postoperative day (POD) 1, and ambulation (success rate, number of footsteps) 6–12 hours after surgery and on POD 1. The pain score for the wound site, IV opioid requirement, postoperative complications including incidences of nausea/vomiting, and length of in-hospital stay were also assessed.Results: The global QoR-40K score and all subscale scores (physical comfort, emotional state, physical independence, psychological support, and pain) were significantly higher in the IV propofol group than in the IH sevoflurane group. The numbers of footsteps at all time points were also higher in the IV propofol group. Donors in the IV propofol group had a lower incidence of nausea/vomiting, and a shorter hospitalization period.Conclusions: Total IV anesthesia with propofol led to better early postoperative recovery than that associated with IH sevoflurane.
The Bilateral Limb Deficit (BLD) Phenomenon During Leg Press: An Investigation Into Central And Peripheral Factors
Authors: Whitcomb Emily , Ortiz Oscar , Toner Jacqueline , Kuruganti Usha 
Published: September 2020

Abstract
Background: The bilateral limb deficit (BLD) phenomenon is the difference in maximal or near maximal force generating capacity of muscles when they are contracted alone or in combination with the contralateral muscles. It has been suggested that the BLD may be due to interhemispheric inhibition, however the origin of the deficit is yet to be determined. The aim of this study was to investigate central and peripheral factors responsible for the BLD during leg press using surface electromyography (EMG) and electroencephalography (EEG). Methods: Fourteen adults (age = 23.7 ± 4.7 years old) completed bilateral (BL), unilateral left (UL) and unilateral right (UR) isometric leg press exercises. Bilateral limb ratio (BLR) was calculated similar to previous studies and surface EMG from three muscles of the quadriceps femoris (vastus lateralis, vastus medialis and rectus femoris) were used to compare signal amplitude in each condition. Movement related cortical potentials (MRCPs) over the left and right motor cortex areas (C3 and C4, respectively) were used to assess brain activity asymmetries reflecting central factors. Results: The BLD was present in ten of the fourteen participants (mean BLR=81.4%). Mean RMS activity demonstrated differences in amplitudes between the quadriceps muscles, however no significant differences were noted between bilateral and unilateral conditions. No significant differences in MRCPs were observed between brain activity of the C3 and C4 electrodes in any of the conditions. Conclusion: This study noted the presence of BLD however the results did not provide evidence of significant limitations in either the EMG and EEG data.

Published: September 2020

Abstract
Background: Tobacco use is associated with exacerbation of tuberculosis (TB) and poor TB treatment outcomes. Integrating tobacco use cessation within TB treatment could improve healing among TB patients. The aim was to explore perceptions of health workers on where and how to integrate tobacco use cessation services into TB treatment programs in Uganda.Methods: Between March and April 2019, nine focus group discussions (FGDs) and eight key informant interviews were conducted among health workers attending to patients with tuberculosis on a routine basis in nine facilities from the central, eastern, northern and western parts of Uganda. These facilities were high volume health centres, general hospitals and referral hospitals. The FGD sessions and interviews were tape recorded, transcribed verbatim and analysed using content analysis to identify themes.Results: Participants indicated that tobacco use cessation activities should be integrated in TB treatment starting from communities when people are still healthy. Cessation should also be implemented in health facilities including referral facilities, and be extended to those who have been healed as they go back to communities. This calls for collaborations beyond health workers to TB treatment supporters, peers and the media. Conclusions: Tobacco use cessation should take place in communities as well as health facilities. Partnerships with media and families are needed. Health system challenges need to be addressed to support effective implementation.
The Green Toad Example: A Comparison of Pattern Recognition Software
Authors: Burgstaller Stephan , Gollmann Günter , Landler Lukas 
Published: September 2020

Abstract
Background Individual identification of animals is important for assessing the size and status of populations. Photo-based approaches, where animals are recognized by naturally occurring and visually identifiable features, such as color patterns, are cost-effective methods for this purpose. We compared five available programs for their power to semi-automatically identify dorsal patterns of the European green toad (Bufotes viridis). Method We created a data set of 200 pictures of known identity, two pictures for each individual, and analyzed the percentage of correctly identified animals for each software. Furthermore, we employed a generalized linear mixed model to identify important factors contributing to correct identifications. We used these results to estimate the population size of our hypothetical population. Conclusions The freely available HotSpotter application was the software which performed by far the best for our green toad example, identifying close to 100% of the photos correctly. The animals’ sex highly significantly influenced detection probability, presumably because of sex-specific differences in the pattern contrast. Population estimates were close to the expected 100 for HotSpotter, but for the other applications population size was highly overestimated. Given the clarity of our results we strongly recommend the HotSpotter software, which is a highly efficient tool for individual pattern recognition.

Authors: Kesharwani Vaibhav , Banjare Mayank 
Published: September 2020

Abstract
India, a country with 28 states and 8 Union territories has seen a rapid increase in COVID-19 cases over a period. While the entry of COVID-19 was random in various states, some states have managed the containment while in some states it has exponentially grown. COVID-19 disease is both virulent and contagious and this disease is not yet having a vaccine or medicine.In this study, research has been done on 4 months of data in 28 states and 8 Union territories. When the study is being conducted India had close to 1.3 million cases ranking 3rd in the world. Therefore, the sample size is quite enough to establish the hypothesis. The study is focused on analyzing and synthesizing testing levers along with population and number of cases. Two constructs namely "Proactiveness Index and Infection Ration" have been devised considering 3 different levers of population, testing, and cases. A relationship has been established and it has been found that in most of the cases Proactive Index and Infection Ration has an inverse relationship i.e. higher the proactive index, the lower the infection ration.
WITHDRAWN: Experimental Study on Characteristics of Reactance Dispersion of Water Bearing Coal
Authors: Lei Dongji , Li Jian , Meng Hui , Wang Yajuan 
Published: September 2020

Abstract
As an emerging geophysical exploration method, complex resistivity method is a potential non-invasive one for evaluating hydrofracturing effect. Reactance X is an important parameter of complex resistivity method. Compared with the traditional parameter resistance R, reactance has advantages such as distinct dispersion characteristics, clear conduction mechanism and rich information. In this paper, reactance X of four kinds of coal sample with different water saturation was tested, their dispersion characteristics were analyzed, and their conductive mechanism was studied. The results show that, (1) the characteristic curve of reactance dispersion presents a three-stage law when the water saturation is low, and a two-stage law when the water saturation is high,to some extent, the water content of coal body and the effect of hydraulic fracturing are distinguished;(2) polarization is the cause of dispersion, in which low frequency is induced polarization, high frequency is dielectric polarization, and electromagnetic induction is the interference phenomenon in the frequency band of induced polarization; (3) spectrum extremum frequency point is sensitive to changed water saturation. Extremum points of different coal rank are concentrated in 100-1000Hz. This frequency band can serve as the dominant frequency band for evaluating coal seam water saturation. This paper gives new insight into the evaluation of coal seam hydrofracturing effect by complex resistivity method.

Abstract
Background: The purpose of this study is to evaluate the new method of time maximum intensity projection (t-MIP) which was postprocessed from dynamic computed tomographic angiography (dyn-CTA) in diagnosing peripheral arterial disease (PAD). Methods: A population of 34 patients with known PAD was examined with a combined CTA protocol consisting of an s-CTA of the lower extremity and a dyn-CTA scan of the calves. For each lower leg, t-MIP images consisting of the MIP0 (sagittal MIP), and MIP+θ (45degree lateral MIP), MIP-θ (-45degree lateral MIP) were automatically generated from dyn-CTA. An objective evaluation of vascular CT attenuation of the best enhancement phase of dyn-CTA and t-MIP was measured; subjective evaluation of vessel stenosis and occlusion with a score was assigned for t-MIP and s-CTA. A comparison between the CT attenuation of t-MIP and dyn-CTA was made, so was the runoff score of t-MIP and s-CTA.Results: The CT attenuation of t-MIP CTA of three vascular segments from 68 lower extremities was higher than that of the best enhancement phase of dyn-CTA and s-CTA, with statistical significant difference at posterior tibial artery and fibular artery (all p＜0.05) . There were strong correlations (r ≥0.75, p < 0.05) of runoff scores between t-MIP and s-CTA. Conclusions: There is potential clinical application of t-MIP for assisting with the diagnosis of lower leg vascular stenosis in dyn-CTA with reliable diagnostic accuracy and convenient immediacy.

Authors: Ahmadian Mohammad , Moghaddam Mohammad Javad Mehdipour 
Published: September 2020

Abstract
Background: The antimicrobial activity of ethanolic and aqueous extracts of the two plants, including Eryngium caucasicum Trautv (EtEc, AqEc) and Froriepia subpinnata (EtFs, AqFs), as well as the essential oil of Eryngium caucasicum (EoFs) on MDR E. coli spp. isolated from the urine samples were examined. Methods: Microdilution and agar well diffusion methods were used to determine the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and inhibition zone diameter of the extracts and essential oil. Reverse-phase High- performance liquid chromatography (RP-HPLC) and gas chromatography-mass spectrometry (GC-mass) were applied for phytochemical analyses of extracts and essential oil ingredients. Results: The inhibitory rate based on MIC of AqEc, EtEc, AqEc, EtEc and EoEs on total isolates were 37.6%, 43%, 31.2%, 40.9% and 53.8%, respectively. The killing rate based on MBC of AqEc, EtEc, AqEc, EtEc and EoFs on total isolates were 15.1%, 20.4%, 12.9%, 24.7% and 34.4%, respectively. EoFs, with the exception of cephalothin, chloramphenicol, pipiracillin and carbapenems, can be used as an alternative to 12 of the 18 antibiotics used (P<0.01). Compounds with antimicrobial activity including quercetin, catechin, terpenes, alcohols and aromatic molecules in extracts and essential oils have been identified and measured, but chlorogenic acid polyphenol could not be identified in any of the plant products. Conclusion: It seems that the extracts and essential oil studied have the potential to be used as native materials to treat urinary tract infections as well as food preservatives or other products.
