Authors: Wahab M I A , Razak W M A A 
Published: August 2019

Abstract
This study aimed to assess the concentrations and health effect of heavy metals (Cd, Cu, Cr, Ni, Pb and Zn) in road dust of selected locations in the city of Kuala Lumpur. Sampling was conducted for three times at four locations namely Jalan Tun Razak, Jalan Raja Abdullah, Jalan TAR and Jalan Ayer Molek. The concentration of heavy metals in road dust was analyzed by using ICP-MS. The study found that Jalan TAR has the highest concentrations for the heavy metals Cd (0.23 ± 0.04 mg/kg), Cu (116.39 ± 38.77 mg/kg), Ni (83.29 ± 23.66 mg/kg), Pb (43.53 ± 7.00 mg/kg) and second highest for Cr (34.69 ± 3.57 mg/kg) and Zn (86.22 ± 23.07). The pollution level of heavy metals in road dust were assessed by Pollution Index and Pollution Load Index, showing that all locations are highly contaminated except Jalan Ayer Molek. Health risk assessment was determined to access the health effect of carcinogenic and non-carcinogenic to adults and children caused by exposure of heavy metals in road dust. Based on the integrated HI for children at all locations are more than 1. Indicating great chance of non-carcinogenic effects. All incremental lifetime cancer risk (ILTCR) values for adult and children at all locations are within acceptable limit. Traffic and activities that take place in these four locations are the sources of heavy metals. Jalan TAR which is loaded with commercial activities is the most polluted location followed by Jalan Raja Abdullah (commercial area), Jalan Tun Razak (highway area) and Jalan Ayer Molek (residential area).

Published: August 2019

Abstract
Starting from the meaning of fractal geometry and fractal art, this paper discusses the artistry of fractal, and draws a conclusion through the introduction and analysis of four kinds of classical fractal patterns, that is, fractal art can be called real art, It can be found that fractal art has great artistic charm and practical value in ceramic product design by applying fractal art pattern to the field of traditional ceramic daily necessities and handicraft design, However, as a designer, the art pattern of fractal processing cannot be directly attached to the surface of ceramic products, Further researches and innovation are needed to make fractal art more suitable for ceramic products and enhance the artistic value of ceramic products.

Authors: Sun Jing , Chu Junjie 
Published: August 2019

Abstract
With the change of business model, market competition has gradually changed from product competition to service competition, and service design has been paid more and more attention by various industries. The ultimate goal of service design is tantamount to bring users a better experience and maximize the interests of stakeholders. Therefore, this paper will create a service design method based on service dominant logic and more emphasis on user experience. This paper sorts and summarizes the concept, content and characteristics of service design and product service system, and then find out the future development direction of service design and product service system. In this paper, various design methods are analyzed and compared, and one of the best design methods is associated with the product service system to form a new design method. After that, this new design method will be applied to the service design of children’s design thinking education as a practice.

Abstract
The topological state that emerges at the surface of a topological insulator (TI) and at the TI-substrate interface are studied in metal–hBN–Bi2Se3 capacitors. By measuring the RF admittance of the capacitors versus gate voltage, we extract the compressibility of the Dirac state located at a gated TI surface. We show that even in the presence of an ungated surface that hosts a trivial electron accumulation layer, the other gated surface always exhibits an ambipolar effect in the quantum capacitance. We succeed in determining the velocity of surface Dirac fermions in two devices, one with a passivated surface and the other with a free surface that hosts trivial states. Our results demonstrate the potential of RF quantum capacitance techniques to probe surface states of systems in the presence of a parasitic density-of-states.

Published: August 2019

Abstract

Aims
To characterize latent typologies of alcohol use among persons living with human immunodeficiency virus (HIV) (PLWH) and test their relationship with physical and mental health status.

Methods
Baseline data from 365 adult in-care PLWH enrolled in the New Orleans Alcohol Use in HIV study were analyzed. Indicators of current and former heavy drinking, intoxication, withdrawal and dependence symptoms, alcohol-related problems and past contact with alcohol use treatment were drawn from validated scales. Physical and mental health measures included SF-36 subscales, medication non-adherence and anxiety, depressive and post-traumatic stress disorder symptoms. Latent class analysis was conducted to characterize alcohol drinking typologies. Logistic and ordinary least-squares regression were employed to test associations between alcohol use and health status.

Results
Four latent classes were identified: heavy drinkers (36%), former heavy drinkers (14%), heavy drinkers with problems (12%) and low-risk drinkers/abstainers (38%). Controlling for background characteristics, low-risk drinkers/abstainers showed significantly better health compared to heavy drinkers with problems across most domains. Although current and former heavy drinkers without alcohol-related problems were similar to heavy drinkers with problems in most health domains, they presented worse mental health and energy compared to low-risk drinkers/abstainers.

Conclusions
Heavy drinkers with alcohol-related problems evidenced the worst health status among PLWH, and should be considered for mental and physical health interventions. However, interventions to improve physical and mental health of PLWH should consider history of heavy alcohol use, as current alcohol use status alone may be insufficient for identifying groups at increased risk.
Male spacing and female choice in a fiddler crab
Authors: Perez Daniela M , Backwell Patricia R Y 
Published: August 2019

Abstract
The aggregation of courting males is widespread among animal taxa, yet we do not understand why males congregate and therefore intensify local competition for female attention. The most commonly invoked theoretical explanation is that females preferentially approach clustered males due to the many benefits they would gain, and clustered males would therefore have higher mating success. However, although theoretical explanations of aggregation formation are well advanced, empirical studies are scarce, especially in invertebrates. In fact, there is little evidence that females do prefer to approach clustered displayers over spaced displayers. Here we address this question by using robotic crabs to test female preferences in fiddler crabs (a visually displaying species) and show that females do not preferentially approach clustered males. We suggest that if this pattern is more widespread, the most commonly invoked explanation of courting aggregations is of limited use. We offer explanations for the strong clustering behavior we observe in this species and discuss the implications of this finding for the theoretical underpinnings of this research field.

AbstractBackgroundOsteoarthritis (OA) is a most common orthopaedic condition, often complicated by inflammatory features.Sources of dataA systematic search in PubMed, Embase, Google Scholar and Scopus databases (to January 2019) was performed to define the effect obtained in patients with OA of the knee by injections of ozone, on pain and physical function. Six RCTs and 353 patients were included.Areas of agreementRecently, an increasing number of physicians have used ozone therapy to alleviate the symptoms of acute and chronic OA of the knee. Ozone can allow greater mobility of the knee joint, pain relief and decrease in effusion.Areas of controversyThe volume and concentration of ozone injected are different in the various treatment protocols published.Growing pointsThe action of ozone is unclear, but it is a promising therapeutic modality capable of impacting, favourably, function and quality of life.Areas timely for developing researchThe lack of a clear protocol of use is a major limitation, and to date there is no clear evidence of long-term efficacy.

Published: August 2019

AbstractBackgroundPosaconazole tablets are well tolerated and efficacious in the prophylaxis and treatment of aspergillosis, mucormycosis, and other invasive fungal infections. There have been case reports of posaconazole-induced pseudohyperaldosteronism (PIPH); however, its occurrence and association with serum posaconazole drug levels have not previously been investigated.MethodsIn this single-center, retrospective, observational study, we examined the occurrence of PIPH in outpatients newly starting posaconazole and evaluated differences in serum posaconazole concentrations and clinical characteristics between those with and without this syndrome.ResultsSixty-nine patients receiving posaconazole were included, of whom 16 (23.2%) met the definition of PIPH. Patients with PIPH were significantly older (61.1 vs 44.7 years, P = .007) and more frequently had hypertension prior to starting posaconazole (68.8% vs 32.1%, P = .009). Patients with PIPH had a significantly higher median serum posaconazole level than those without PIPH (3.0 vs 1.2 µg/mL, P ≤ .0001). There was a positive correlation between serum posaconazole levels and changes in systolic blood pressure (r = .37, P = .01), a negative correlation between serum posaconazole levels and changes in serum potassium (r = –.39, P = .006), and a positive correlation between serum posaconazole levels and serum 11-deoxycortisol (r = .69, P &lt; .0001).ConclusionsPosaconazole is associated with secondary hypertension and hypokalemia, consistent with pseudohyperaldosteronism, and development is associated with higher serum posaconazole concentrations, older age, and baseline hypertension.
Relative Assortativity Index: A Quantitative Metric to Assess the Impact of Link Prediction Techniques on Assortativity of Complex Networks
Authors: Meghanathan Natarajan 
Published: August 2019

Abstract
We propose a quantitative metric (called relative assortativity index, RAI) to assess the extent with which a real-world network would become relatively more assortative due to link addition(s) using a link prediction technique. Our methodology is as follows: for a link prediction technique applied on a particular real-world network, we keep track of the assortativity index values incurred during the sequence of link additions until there is negligible change in the assortativity index values for successive link additions. We count the number of network instances for which the assortativity index after a link addition is greater or lower than the assortativity index prior to the link addition and refer to these counts as relative assortativity count and relative dissortativity count, respectively. RAI is computed as (relative assortativity count − relative dissortativity count) / (relative assortativity count + relative dissortativity count). We analyzed a suite of 80 real-world networks across different domains using 3 representative neighborhood-based link prediction techniques (Preferential attachment, Adamic Adar and Jaccard coefficients [JACs]). We observe the RAI values for the JAC technique to be positive and larger for several real-world networks, while most of the biological networks exhibited positive RAI values for all the three techniques.

Published: August 2019

AbstractBackgroundInflammatory bowel disease (IBD) patients are often counseled to pause anti-tumor necrosis factor (TNF) therapy before surgery. Here, we assessed the effects of preoperative anti-TNF treatment on bowel resection complications.MethodsA national database analysis was performed. IBD patients who underwent bowel resection were included. Patients using preoperative anti-TNF were stratified by treatment regimen. Complication rates were compared between these groups and a control group with no anti-TNF history.ResultsTwenty thousand and sixty-eight patients matched our criteria. We observed no significant differences between preoperative anti-TNF regimens and postoperative bowel resection complications.ConclusionsThese data suggest that anti-TNF therapy may safely be continued prior to bowel resection.
Anti-thrombotic strategies in elderly patients receiving platelet inhibitors
Authors: Schäfer Andreas , Flierl Ulrike , Bauersachs Johann 
Published: August 2019

Abstract
Acetyl-salicylic acid is the basic anti-thrombotic therapy used for single anti-platelet therapy in primary as well as secondary prevention of atherosclerotic disease. Dual anti-platelet therapy (DAPT) is the cornerstone of maintenance medication following elective percutaneous coronary intervention or acute coronary syndromes (ST elevation myocardial infarction, non-ST elevation myocardial infarction, unstable angina). DAPT duration has been frequently discussed. Currently, guideline recommendations strengthen the importance of individualized treatment to reduce bleeding risk based on clinical predictors, of which older age is an important one. Patients aged ≥75 years are often underrepresented in randomized clinical trials, but present a patient cohort deemed both at heightened ischaemic as well as bleeding risk. We aimed to summarize the evidence or the lack of evidence for anti-platelet treatment strategies in patients aged ≥75 years including combinations with anticoagulants in secondary prevention or coronary interventions in elderly patients with atrial fibrillation. This review article represents the author’s interpretation of available data and is not discussed by a formal task force; it is intended to point out missing evidence and to provide age-specific data for individualized decision making, which is currently encouraged by the guidelines.
Who Initiates the Help Older Parents Give to Midlife Children

Published: August 2019

Abstract

Objectives
Older parents continue to help children after these children have been adults for decades. We utilize a typology approach to assess who initiates the help. We ask whether profiles of help initiation are associated with how often older parents help and how they evaluate their helping behaviors.

Methods
Older parents (N = 241; Mage = 80.12) indicated the extent to which they volunteered to help children and helped per child’s request. Parents reported their resources and obligation to help, child problems, frequency, and evaluation (rewards/stresses) of helping.

Results
Latent profile analysis reveals four profiles representing parents who are initiators (n = 65), responders (n = 56), initiators/responders (n = 50), and uninvolved (n = 69). Resources, needs, and individual beliefs differentiate profiles. Parents offer the same amount of help regardless of who initiates such help. Parents who are initiators/responders view helping as more rewarding than parents who are initiators and more stressful than uninvolved parents.

Discussion
This study reveals variation in the initiation of older parents’ help and refines our understanding of family help in late life. Findings may suggest a parental expectation for children to be competent in adulthood regardless of their resources and willingness to help.
Desert low-frequency noise suppression by using adaptive DnCNNs based on the determination of high-order statistic
Authors: Dong X T , Li Y , Yang B J 
Published: August 2019

SUMMARY
The importance of low-frequency seismic data has been already recognized by geophysicists. However, there are still a number of obstacles that must be overcome for events recovery and noise suppression in low-frequency seismic data. The most difficult one is how to increase the signal-to-noise ratio (SNR) at low frequencies. Desert seismic data are a kind of typical low-frequency seismic data. In desert seismic data, the energy of low-frequency noise (including surface wave and random noise) is strong, which largely reduces the SNR of desert seismic data. Moreover, the low-frequency noise is non-stationary and non-Gaussian. In addition, compared with seismic data in other regions, the spectrum overlaps between effective signals and noise is more serious in desert seismic data. These all bring enormous difficulties to the denoising of desert seismic data and subsequent exploration work including geological structure interpretation and forecast of reservoir fluid. In order to solve this technological issue, feed-forward denoising convolutional neural networks (DnCNNs) are introduced into desert seismic data denoising. The local perception and weight sharing of DnCNNs make it very suitable for signal processing. However, this network is initially used to suppress Gaussian white noise in noisy image. For the sake of making DnCNNs suitable for desert seismic data denoising, comprehensive corrections including network parameter optimization and adaptive noise set construction are made to DnCNNs. On the one hand, through the optimization of denoising parameters, the most suitable network parameters (convolution kernel、patch size and network depth) for desert seismic denoising are selected; on the other hand, based on the judgement of high-order statistic, the low-frequency noise of processed desert seismic data is used to construct the adaptive noise set, so as to achieve the adaptive and automatic noise reduction. Several synthetic and actual data examples with different levels of noise demonstrate the effectiveness and robustness of the adaptive DnCNNs in suppressing low-frequency noise and preserving effective signals.

Abstract
Local coalitions can advance public health initiative but have not been widely used or well-studied in low- and middle-income countries. This paper provides (i) an overview of an ongoing matched-pairs community-randomized controlled trial in 28 communities in Armenia and Georgia (N = 14/country) testing local coalitions to promote smoke-free policies/enforcement and (ii) characteristics of the communities involved. In July–August 2018, key informants (e.g. local public health center directors) were surveyed to compare their non-communicable disease (NCD) and tobacco-related activities across countries and across condition (intervention/control). More than half of the informants (50.0–57.1%) reported their communities had programs addressing hypertension, diabetes, cancer and human papilloma virus, with 85.7% involving community education and 32.1% patient education programs. Eleven communities (39.3%) addressed tobacco control, all of which were in Georgia. Of those, all included public/community education and the majority (72.7–81.8%) provided cessation counseling/classes, school/youth prevention programs, healthcare provider training or activities addressing smoke-free environments. Informants in Georgia versus Armenia perceived greater support for tobacco control from various sectors (e.g. government, community). No differences were found by condition assignment. This paper provides a foundation for presenting subsequent analyses of this ongoing trial. These analyses indicate wide variability regarding NCD-related activities and support across communities and countries.
