Authors: Bukovec Mitja , Xhanari Klodian , Finšgar Matjaž 
Published: September 2020

AbstractThis study reports the development of frits with different composition, time, and firing temperature for mitigating the corrosion of AA2024, AA6082, and AA7075 aluminium alloys in chloride‐containing solutions. The melting points of the frits were determined using a heating microscope, while the thermal expansion was measured using dilatometry. Several frits were prepared, of which seven were coated on AA2024, AA6082 and AA7075 aluminium alloys. The corrosion resistance of the coated samples was tested in 5 wt% NaCl solution at 25°C using potentiodynamic curve measurements. The corrosion resistance of the coated samples increased compared with the respective uncoated aluminium alloys. The composition and in‐depth homogeneity of the best‐performing coated samples were confirmed using a gas cluster ion beam sputtering source associated with X‐ray photoelectron spectroscopy analysis. Furthermore, O2+ sputtering was performed in association with time‐of‐flight secondary ion mass spectrometry to describe the three‐dimensional composition of the frits.
Using website information to reduce postpurchase dissonance: A mediated moderating role of perceived risk
Authors: Li Mingfang , Choudhury Askar H. 
Published: September 2020

AbstractA significant body of research is dedicated to decreasing the product return rate by applying management measures that identify the factors and causes of returns. These studies examine how consumers' product return behavior can be explained by studying the information on retailers' websites. However, these studies have not shown how website information (WI) is linked to product returns. The study by Lee's work observed how product returns are motivated by consumers' need to mitigate postpurchase dissonance (PPD). However, a clear understanding of the relationship between WI and PPD is lacking. Therefore, our research examines the impact of WI on PPD in the product returns context. In our research, PPD serves as a key factor in understanding the linkage between WI and product returns. Our results showed that higher‐quality WI is associated with a lower level of PPD. In addition, a lower perceived risk (PR) or attractiveness of alternatives strengthens the association between WI and PPD. We also observed that PR partially mediated the moderation effect of the attractiveness of alternatives. These findings will help e‐retailers better understand customers' PPD, easing the process of reducing product returns.

ABSTRACTBackgroundX‐linked dystonia‐parkinsonism is a rare neurological disease endemic to the Philippines. Dystonic symptoms appear in males at the mean age of 40 years and progress to parkinsonism with degenerative pathology in the striatum. A retrotransposon inserted in intron 32 of the TAF1 gene leads to alternative splicing in the region and a reduction of the full‐length mRNA transcript.ObjectivesThe objective of this study was to discover cell‐based and biofluid‐based biomarkers for X‐linked dystonia‐parkinsonism.MethodsRNA from patient‐derived neural progenitor cells and their secreted extracellular vesicles were used to screen for dysregulation of TAF1 expression. Droplet‐digital polymerase chain reaction was used to quantify the expression of TAF1 mRNA fragments 5′ and 3′ to the retrotransposon insertion and the disease‐specific splice variant TAF1‐32i in whole‐blood RNA. Plasma levels of neurofilament light chain were measured using single‐molecule array.ResultsIn neural progenitor cells and their extracellular vesicles, we confirmed that the TAF1‐3′/5′ ratio was lower in patient samples, whereas TAF1‐32i expression is higher relative to controls. In whole‐blood RNA, both TAF1‐3′/5′ ratio and TAF1‐32i expression can differentiate patient (n = 44) from control samples (n = 18) with high accuracy. Neurofilament light chain plasma levels were significantly elevated in patients (n = 43) compared with both carriers (n = 16) and controls (n = 21), with area under the curve of 0.79.ConclusionsTAF1 dysregulation in blood serves as a disease‐specific biomarker that could be used as a readout for monitoring therapies targeting TAF1 splicing. Neurofilament light chain could be used in monitoring neurodegeneration and disease progression in patients. © 2020 The Authors.

Published: September 2020

AbstractBackgroundGroup‐based trajectory modeling has been applied to identify distinct trajectories of growth across the life course. Objectives of this study were to describe the methodological approaches for group‐based modeling of growth across the life course and to summarize outcomes across studies.MethodsA scoping review with a systematic search of Medline, EMBASE, CINAL, and Web of Science was conducted. Studies that used a group‐based procedure to identify trajectories on any statistical software were included. Data were extracted on trajectory methodology, measures of growth, and association with outcomes.ResultsA total of 59 studies were included, and most were published from 2013 to 2020. Body mass index was the most common measure of growth (n = 43). The median number of identified trajectories was 4 (range: 2–9). PROC TRAJ in SAS was used by 33 studies, other procedures used include TRAJ in STATA, lcmm in R, and Mplus. Most studies evaluated associations between growth trajectories and chronic disease outcomes (n = 22).ConclusionsGroup‐based trajectory modeling of growth in adults is emerging in epidemiologic research, with four distinct trajectories observed somewhat consistently from all studies. Understanding life course growth trajectories may provide further insight for population health interventions.

Published: September 2020

AbstractThe thermal properties of a sorbitol‐type nucleating agent (viz. 1,2,3‐trideoxy‐4,6:5,7‐bis‐O‐[(4‐propylphenyl)methylene]‐nonitol (TBPMN)) were examined in this study, and the influence of common processing additives assessed. In addition, we describe a novel approach to monitor in situ the self‐assembly of the nucleator in presence of additives by optical microscopy. The performance of sorbitol compounds is closely associated to their chemical structure and ability to self‐assemble. TBPMN formed elongated fibrils from the melt under inert atmosphere, in molted polypropylene, or in presence of antioxidants. However, calcium stearate (CaSt) and glycerol monostearate hampered growth, and yielded thinner fibrils. In presence of the additives, melting point depression of the nucleator occurred, and resulted in a lower degree of crystallinity upon cooling. Performance evaluation of the nucleator in polypropylene blends revealed an increased crystallization temperature when antioxidants were present, while CaSt inhibited nucleator activity. The effect of mono‐glycerides was found highly dependent on the processing conditions. Noteworthy, blends containing all the additives displayed the highest performance. This study highlights the importance of the preparation method of polymer additive blends to achieving the best performance in the final product. Characterization was performed by thermogravimetric analysis, Fourier‐transform infrared spectroscopy, optical microscopy, and differential scanning calorimetry.

Published: September 2020

AbstractBACKGROUNDThe southern armyworm, Spodoptera eridania, is a polyphagous species native to the American tropics that recently invaded Africa. Knowledge of the impact of temperature on its development and survival is important to understand the risks of this species spreading to other regions and to develop phenological models for pest management. This study evaluated the effects of temperature on the development and survival of S. eridania and selected mathematical models to simulate its development.RESULTSThe southern armyworm completed its development between 15 and 32 °C, but eggs did not hatch at 34 °C. Lower survival and higher rates of deformities in adults were recorded at 15 and 32 °C. Among the ten mathematical models evaluated, Briere‐2, Lactin‐2 and Shi were considered suitable for describing the temperature‐dependent development rate of S. eridania. The lower thermal threshold estimated by these models for the egg to adult life cycle ranged from 10.8 to 12.1 °C, whereas the upper threshold ranged between 33.9 and 35.0 °C.CONCLUSIONSThe southern armyworm can develop within a wide range of temperatures, which partially explains its wide distribution in regions with different climatic conditions, and demonstrates its potential to occur in regions outside its native range. Our findings can be employed in the development of management strategies using the selected models to predict the occurrence of S. eridania in the field and determine the most effective times to implement control measures.

AbstractThe Purapel watershed in central Chile has experienced drastic land‐use changes since the 1950s, beginning with the conversion of native forests to forest plantations. Controversy exists on the effects of reforestation on sediment production in watersheds. The temporal evolution of stage–discharge curves and sediment production was evaluated and correlated with historic sediment deposition at the Purapel watershed's main gauging station. Annual stage–discharge curves and the evolution of the stage–discharge relationship over time were developed. Trends were generated using the Mann‐Kendall statistical test, comparing results with the evolution of sediment downstream. Obtained results denote a positive and significant trend at flows greater than 90 m3 s−1 (Z = 2.77). This can be explained by major flows that deepen the bed, which is consistent with a significant and sustained decrease in channel width (Z = −2.51) and the production of sediments (Z = −2.49). Similarly, the average annual number of curves decreased from 1.7 to 1.4. This analysis supports the conclusion that sediment production from the Purapel watershed drastically decreased after the majority of forest plantations were established around 1990, with important implications on how to retain sediments on degraded slopes through large‐scale afforestation projects, as well as the necessary politics to make it happen.

AbstractSoftware defined networking (SDN) can be understood as a software control system, built over a centralized system that controls a network's forwarding rule. SDN can be used in an enterprise, in a data center, or even in a household. It was the solution to one of the biggest problems when at times we had to do the manual configuration of all the devices. SDN has not only made networks easier to manage but it has also made it secure. SDN is based on logical centralization that again brings a wide range of challenging scenarios related to security threats. So, there is a need to bring a new way to address this problem. In this paper, we embrace a thorough overview of the latest works that applies security to SDN, proposed an advanced secure software defined network architecture and then, evaluated its performance with the existing models using mininet tool.

Authors: Unterweger Harald , Kettler Markus , Zauchner Paul 
Published: September 2020

AbstractDurch Forschungsergebnisse der Technischen Universität Graz konnte gezeigt werden, dass im Falle geschraubter Winkelprofile die Steifigkeit der beidseitigen Anschlusskonstruktion großen Einfluss auf die Drucktragfähigkeit aufweist. Für baupraktische Anschlussformen wurden Formeln zur Ermittlung äquivalenter Drehfedersteifigkeiten abgeleitet und daraus ein Bemessungsmodell zur Ermittlung der Drucktragfähigkeit entwickelt, das die volle Bandbreite vom gelenkigen bis zum voll eingespannten Anschluss abdeckt. Dieses Bemessungsmodell erfordert die elastische Schnittkraftberechnung nach Theorie II. Ordnung an einem Einzelstab, mit Exzentrizität und Drehfederstützung am Ende, unter Ansatz einer geometrischen Ersatzimperfektion e0. Dabei wird der elastische Querschnittswiderstand des Winkelprofils zugrunde gelegt. Das im Beitrag dargestellte Bemessungsmodell wurde durch umfangreiche numerische Berechnungen – auch kalibriert an Einzelversuchen – validiert und angepasst, worauf ebenfalls näher eingegangen wird. Damit ist auch sichergestellt, dass komplexe Versagensformen mit überlagertem Biegedrillknickversagen mit abgedeckt werden.

Published: September 2020

AbstractThis work aims to understand the physicochemical properties of potato starch nanoparticles (SNPs) obtained by anti‐solvent precipitation. Moisture content, water activity, color, morphology, thermal behavior (differential scanning calorimetry), swelling factor, solubility in water, water sorption isotherms, rheological properties, and stability in water are analyzed and compared using native potato starch (PS) as control. The resulting SNPs after anti‐solvent precipitation have a particle size between 50 and 150 nm, smaller than those observed in PS (between 10 and 100 µm). SNPs behave as an amorphous material without gelatinization stage where the swelling factor is drastically reduced, while the solubility increased dramatically at low temperatures when compared with PS. The Guggenheim–Anderson–de Boer model from the isotherms data allows a calculation of the surface area, obtaining values of 105 and 211 m2 g−1 for PS and SNPs, respectively. The high surface area in SNPs is associated with an increase in the proportion of hydroxyl groups active for water adsorption throughout its structure. Both samples show Newtonian fluid behavior; however, SNPs solutions prove to be much more stable at room temperature than PS solution.

AbstractThe effectiveness of rice husk–activated carbon (RHAC) in the adsorption of Cr(VI) from an aqueous solution was investigated. The adsorbent was prepared, characterized, and subjected to optimization, kinetics, and thermodynamics studies. Optimization was done using response surface methodology (RSM) based on the Box–Behnken design. Accordingly, optimum adsorption factors obtained were shaking speed of 176.90 rpm, adsorbent dosage of 1.96 g, and initial concentration of 50.12 mg/L for 93.49% removal of Cr(VI) at a desirability of 1.00. The maximum adsorption capacity obtained was 98.14 mg/g. An equilibrium adsorption isotherm model and a kinetic model of Cr(VI) on RHAC were fitted to experimental data. The data were well represented by the Freundlich adsorption isotherm model, with R2 of 0.9956, which presumes an energetically heterogeneous surface. Furthermore, the adsorption kinetic data were well described by the pseudo‐second order model with R2 range of 0.9969–0.9997, indicating a high agreement between experimental and calculated values. Finally, thermodynamic parameters such as mean Gibbs free energy (∆G) showed that adsorption of Cr(VI) ions onto RHAC was spontaneous and endothermic under examined conditions. In this view, RHAC is a viable adsorbent for the optimum removal of Cr(VI) ions from wastewater.

Abstract
One of the main challenges in 3d-3d correspondence is that no existent approach offers a complete description of 3d $$ \mathcal{N} $$
N
= 2 SCFT T [M3] — or, rather, a “collection of SCFTs” as we refer to it in the paper — for all types of 3-manifolds that include, for example, a 3-torus, Brieskorn spheres, and hyperbolic surgeries on knots. The goal of this paper is to overcome this challenge by a more systematic study of 3d-3d correspondence that, first of all, does not rely heavily on any geometric structure on M3 and, secondly, is not limited to a particular supersymmetric partition function of T [M3]. In particular, we propose to describe such “collection of SCFTs” in terms of 3d $$ \mathcal{N} $$
N
= 2 gauge theories with “non-linear matter” fields valued in complex group manifolds. As a result, we are able to recover familiar 3-manifold invariants, such as Turaev torsion and WRT invariants, from twisted indices and half-indices of T [M3], and propose new tools to compute more recent q-series invariants $$ \hat{Z} $$

(M3) in the case of manifolds with b1> 0. Although we use genus-1 mapping tori as our “case study,” many results and techniques readily apply to more general 3-manifolds, as we illustrate throughout the paper.

Published: September 2020

AbstractBackgroundRacial disparities in surgery are increasingly recognized. We evaluated the impact of race on presentation, preoperative evaluation, and surgical outcomes for patients undergoing parathyroidectomy for primary hyperparathyroidism (PHPT).MethodsWe performed a retrospective cohort study of patients undergoing parathyroidectomy for PHPT at a single center (1997–2015). Patients were classified by self‐identified race, as African‐American or White. The primary outcome was disease severity at referral. The secondary outcome was completeness of preoperative evaluation. Operative success and surgical cure were evaluated.ResultsA total of 2392 patients were included. The majority of patients (87.6%) were White. African‐American patients had higher rates of comorbid disease as well as higher preoperative calcium (10.9 vs.10.8 mg/dl, p < 0.001) and PTH levels (122 vs. 97 pg/ml, p < 0.001). White patients were more likely to have history of bone loss documented by DXA and nephrolithiasis. African‐American patients had lower rates of complete preoperative evaluation including DXA scan. Operatively, African‐American patients had larger glands by size (1.7 vs. 1.5 cm, p < 0.001) and mass (573 vs. 364 mg, p < 0.001). We observed similar operative success (98.9 vs. 98.0%, p = 0.355) and cure rates (98.3 vs. 97.0%, p = 0.756).ConclusionsAt the time of surgical referral, African‐American patients with PHPT have more biochemically severe disease and higher rates of incomplete evaluation. Operative success and cure rates are comparable.
The toolbox of porous anodic aluminum oxide–based nanocomposites: from preparation to application
Authors: Huang Xia , Mutlu Hatice , Théato Patrick 
Published: September 2020

AbstractAnodic aluminum oxide (AAO) templates have been intensively investigated during the past decades and have meanwhile been widely applied through both sacrificial and non-sacrificial pathways. In numerous non-sacrificial applications, the AAO membrane is maintained as part of the obtained composite materials; hence, the template structure and topography determine to a great extent the potential applications. Through-hole isotropic AAO features nanochannels that promote transfer of matter, while anisotropic AAO with barrier layer exhibits nanocavities suitable as independent and homogenous containers. By combining the two kinds of AAO membranes with diverse organic and inorganic materials through physical interactions or chemical bonds, AAO composites are designed and applied in versatile fields such as catalysis, drug release platform, separation membrane, optical appliances, sensors, cell culture, energy, and electronic devices. Therefore, within this review, a perspective on exhilarating prospect for complementary advancement on AAO composites both in preparation and application is provided.
