AbstractAimsTo develop an online platform to facilitate evidence‐based self‐management of lower urinary tract symptoms (LUTS) in men.MethodsUsing the PubMed database (search until January 2017) and relevant guidelines, we reviewed evidence for the self‐management of LUTS and identified suitable components for the intervention. Next, we built an algorithm that provided individualized advice based on patient characteristics and symptoms for use on an online platform. Men with LUTS tested the usability of the intervention and provided feedback. Finally, we surveyed urologists and general practitioners to identify potential areas for improvement of the intervention.ResultsWe identified nine self‐help interventions from 48 eligible publications. These were as follows: information and education about LUTS, pelvic floor muscle training, bladder training, urethral milking, double voiding, caffeine management, alcohol management, fluid management, and exercise advice. The level of evidence for each item was low due to the paucity of research available. Six men with LUTS reported difficulties understanding and completing the frequency‐volume chart online. The 158 surveyed physicians agreed (≥50% positive ratings) on the inclusion of seven advice items, but not for double voiding and fluid management. Respondents noted that some advice should be provided to all men with LUTS, while other advice should only be presented to certain groups. Some recommendations for additions were offered.ConclusionsDespite a lack of evidence for the self‐management advice, physicians agreed with most of the included advice. The online platform needs further development. Therefore, adjustments will be made and we will assess its impact in future studies.

AbstractMajor depressive disorder (MDD) is a severe mood disorder that may lead to use of drugs, alcohol, and even suicide in acute cases. It has been shown that neurotransmitters and hormones have the same receptors and pathways in the mood area of the brain. Therefore, metabolic and biochemical changes are expected in MDD and, in such diseases, understanding the hormonal alterations would be extremely helpful in the management or treatment with hormone replacement therapy. We evaluated levels of cortisol, adrenocorticotropic hormone (ACTH), testosterone, thyroid‐stimulating hormone (TSH), thyroxine (T4), triiodothyronine (T3), free thyroxine index (FT4I), T3 resin uptake (T3RU), and dehydroepiandrosterone sulfate (DHEA‐S) in 79 patients suffering from MDD and 71 healthy controls. The existence of MDD was confirmed by a face‐to‐face structured clinical interview. We started the investigation by taking a blood sample from the study population. Then, hormone levels were measured by enzyme‐linked immunosorbent assay. Significant differences were found between TSH, FT4I, DHEA‐S, ACTH, testosterone, and cortisol/DHEA‐S ratio in MDD patients compared to the healthy controls. We also demonstrated a correlation between MDD recurrence and FT4I index and TSH, respectively. Regarding some hormonal changes in patients with MDD, hormonal shifts should be considered in the treatment or management of MDD patients.
Improved photovoltaic performance of monocrystalline silicon solar cell through luminescent down‐converting Gd2O2S:Tb3+ phosphor

Published: May 2019

AbstractThis work reports on efforts to enhance the photovoltaic performance of standard p‐type monocrystalline silicon solar cell (mono‐Si) through the application of ultraviolet spectral down‐converting phosphors. Terbium‐doped gadolinium oxysulfide phosphor and undoped‐gadolinium oxysulfide precursor powders were prepared by a controlled hydrothermal decomposition of a urea homogeneous precipitation method. The resulting rare‐earth element hydroxycarbonate precursor powders were then converted to the oxysulfide by annealing at 900°C in a sulfur atmosphere. The as‐prepared phosphors were encapsulated in ethylene vinyl acetate co‐polymer resin and applied on the textured surface of solar cell using rotary screen printing. Comparative results from X‐ray powder diffraction, field emission scanning electron microscopy, scanning transmission electron microscopy, and photoluminescence spectroscopy studies on the microstructure and luminescent properties of the materials are reported. We also compared the optical reflectance and external quantum efficiency response of the cells with and without a luminescent phosphor layer. The results obtained on the terbium‐doped gadolinium oxysulfide phosphor show clearly that the down‐conversion effect induced by the terbium dopant play a crucial role in enhancing the photovoltaic cells' performance. Under an empirical one‐sun illumination, the modified cells showed an optimum enhancement of 3.6% (from 16.43% to 17.02%) in conversion efficiency relative to bare cells. In the concentration range of 1 to 2.5 mg/mL, EVA/Gd2O2S (blank) composites also improve electrical efficiency, but not as much as EVA/Gd2O2S:Tb3+ composites.
The influence of data on teachers' judgments of students' early reading and math skills
Authors: McKevett Nicole M. , Kiss Allyson J. 
Published: May 2019

AbstractTeachers' judgments of student achievement are a crucial aspect of instruction and intervention. Previous research examining teachers' judgments has primarily focused on oral reading fluency and results are mixed with respect to how accurate teachers are. The purpose of the current study was to examine the accuracy of kindergarten and first‐grade teachers' judgments of students' instructional level in early reading and early math and, using a pre‐post quasi‐experimental design, determine the extent to which the use of data altered teachers' judgments. Teachers were least accurate when rating students whose skills were in the frustrational range and they tended to overestimate students' skills. The use of data did not improve accuracy overall, but there were slight (albeit not significant) changes at the frustrational and instructional levels. Results suggest that teachers' low accuracy, when compared with screening data, combined with overestimation, may result in students who most need intervention being missed.

Published: May 2019

AbstractObjectiveEngaging in shared decision‐making may be particularly difficult for adolescents and young adults with cancer (AYAs), possibly because of lower levels of health literacy. Family members of AYAs are likely to support decision‐making about their healthcare by contributing to health literacy skills/practices; however, the nature of this process is unclear. This systematic review synthesized qualitative studies that explored the process of decision‐making and characterized how AYA healthcare information is shared, from the perspective of the AYA and their family members.MethodsElectronic searches of EMBASE, MEDLINE, PsycINFO, and CINAHL were conducted in May 2018. Peer‐reviewed studies discussing the decision‐making process in AYAs and/or their families were eligible for inclusion. Findings were analyzed thematically using Framework analysis.ResultsSeven thousand two hundred seventy‐three studies were screened, and 14 eligible studies were included. The synthesized themes aligned with the Supported Health Literacy Pathway model3 in that AYAs draw on their family members' knowledge, skills, and practices to generate informed options and make shared decisions. Families of AYAs were found to be involved throughout all stages of decision‐making. The use of health literacy skills was also found to be distributed in families, such that family members of AYAs mediate access to knowledge and use of health information in the decision‐making process.ConclusionsOur findings suggest that health literacy is a dynamic and transactional process and provide clinicians, researchers, and other stakeholders with a framework to foster AYA engagement in decision‐making.
Ion impingement effect on the structure and optical properties of TixSi1−xO2 films deposited by ICP‐PECVD
Authors: Li Dayu , Dai Shuyu , Goullet Antoine , Granier Agnès 
Published: May 2019

AbstractTixSi1−xO2 films are grown by plasma‐enhanced chemical vapor deposition from oxygen‐rich O2/titanium tetraisopropoxide/hexamethyldisiloxane radiofrequency inductively coupled plasmas at low pressure. By applying a substrate bias of −50 V, the ion energy is increased from 15 to 75 eV, which has almost no effect on the by‐products, whereas the deposition rate is decreased and the Ti/Si atomic ratio in the film is increased. For the lowest hexamethyldisiloxane fraction in precursor, applying a −50 V bias leads to the formation of TiO2 in rutile phase in the film. The film optical properties (optical index and band gap) are shown to be mainly governed by the film chemical composition.

The Shannon entropy of high‐dimensional hydrogenic and harmonic systems

Published: May 2019

AbstractThere exists an increasing interest on the dimensionality dependence of the entropic properties for the stationary states of the multidimensional quantum systems in order to contribute to its emergent informational representation, which extends and complements the standard energetic representation. Nowadays, this is specially so for high‐dimensional systems as they have been recently shown to be very useful in both scientific and technological fields. In this work, the Shannon entropy of the discrete stationary states of the high‐dimensional harmonic (ie, oscillator‐like) and hydrogenic systems is analytically determined in terms of the dimensionality, the potential strength, and the state's hyperquantum numbers. We have used an information‐theoretic methodology based on the asymptotics of some entropy‐like integral functionals of the orthogonal polynomials and hyperspherical harmonics which control the wave functions of the quantum states, when the polynomial parameter is very large; this is basically because such a parameter is a linear function of the system's dimensionality. Finally, it is shown that the Shannon entropy of the D‐dimensional harmonic and hydrogenic systems has a logarithmic growth rate of the type D log D when D → ∞.

AbstractDiamond has attracted great interest as a quantum technology platform thanks to its optically active nitrogen vacancy (NV) center. The NV's ground state spin can be read out optically, exhibiting long spin coherence times of ≈1 ms even at ambient temperatures. In addition, the energy levels of the NV are sensitive to external fields. These properties make NVs attractive as a scalable platform for efficient nanoscale resolution sensing based on electron spins and for quantum information systems. Diamond photonics enhance optical interactions with NVs, beneficial for both quantum sensing and information. Diamond is also compelling for microfluidic applications due to its outstanding biocompatibility, with sensing functionality provided by NVs. However, it remains a significant challenge to fabricate photonics, NVs, and microfluidics in diamond. In this Progress Report, an overview is provided of ion irradiation and femtosecond laser writing, two promising fabrication methods for diamond‐based quantum technological devices. The unique capabilities of both techniques are described, and the most important fabrication results of color center, optical waveguide, and microfluidics in diamond are reported, with an emphasis on integrated devices aiming toward high performance quantum sensors and quantum information systems of tomorrow.
High‐Yielding Synthesis of 5‐(alkoxymethyl)furfurals from Biomass‐Derived 5‐(halomethyl)furfural (X=Cl, Br)
Authors: Onkarappa Sharath Bandibairanahalli , Dutta Saikat 
Published: May 2019

AbstractA series of 5‐(alkoxymethyl)furfurals (AMFs) have been synthesized in excellent isolated yields (>90%) by reacting biomass‐derived 5‐(chloromethyl)furfural (CMF) or 5‐(bromomethyl)furfural (BMF) with monohydric alkyl alcohols (methanol to 1‐butanol) at slightly elevated temperatures (RT‐50 °C) and short reaction time (3 h). The modified work‐up procedure minimizes side reactions while simplifying the isolation and purification of AMFs. Although higher primary alcohols like 1‐pentanol and 1‐hexanol and secondary alcohol like 2‐propanol were found to be less reactive, use of N,N‐diisopropylethylamine (DIPEA) as a base additive afforded AMFs in excellent yields within 6 h at 65 °C using only slight excess of the alcohol (1.2 eq.) reagent.

Published: May 2019

AbstractChemically activated graphitic mesoporous carbon was synthesized from rice husk biomass and subsequently immobilized with palladium nanoparticles (Pd NPs). The physiochemical characteristics like composition, morphology, structure and textural properties of the rice husk derived activated carbon supported Pd NPs (nano‐Pd@RAGC) were analyzed by various analytical and spectroscopic techniques. Finally, the applications of hybrid nano‐Pd@RAGC material were investigated in useful carbon‐carbon bond forming reactions via Mizoroki‐Heck/Suzuki/Sonogashira cross‐coupling reactions under ligand‐free, microwave conditions. The RAGC provides excellent stability to Pd NPs in cross coupling reactions. The catalyst was recovered simply by filtration and recycled for at least ten times.

Published: May 2019

AbstractHollow spherical ZnO and hollow ZnO−Ag nanocomposites with variable percentage of loading of Ag content were successfully fabricated through a novel, template free and easily reproducible route. Extensive characterizations were carried out using FTIR, XRD, XPS, BET, TEM and SEM. The hollow morphology of the particle and the composite encouraged a detailed photocatalysis study in comparison to solid commercial ZnO and the corresponding ZnO−Ag composite. The photocatalytic activity of the hollow particle and the composite was assessed monitoring the decolouration of methylene blue dye using UV‐Vis absorption spectroscopic technique. An increased surface area for hollow morphology as compared to solid particles established a conspicuous boost in photocatalytic activity.

Published: May 2019

AbstractHere, new series of the 2‐hydroxyethyl‐substituted (NHC)PdI2(pyridine) (Pd‐PEPPSI) complexes have been synthesized. These complexes have been prepared from the 2‐hydroxyethyl‐substituted N‐heterocyclic carbene (NHC) precursors, palladium chloride and pyridine. The synthesized Pd‐PEPPSI complexes have been characterized by using 1H NMR, 13C NMR, FTIR spectroscopy and elemental analysis techniques. The catalytic activity of the 2‐hydroxyethyl‐substituted Pd‐PEPPSI complexes has been examined in the Sonogashira cross‐coupling reaction by using phenylacetylene and aryl bromide. The Pd‐PEPPSI complexes have demonstrated great activity in the Sonogashira cross‐coupling reaction. The molecular and crystal structures of the three of the Pd‐PEPPSI complexes were determined by single‐crystal X‐ray diffraction method. X‐ray studies show that all the molecular structures adopt slightly distorted square‐planar geometry around the palladium (II) center.
Controlling the Reduction Extent for Metal Catalysts
Authors: Li Ming , Cheng Kai , Ren Jiazheng , Chen Yongsheng 
Published: May 2019

AbstractMetal catalysts have been used extensively in addressing energy and environmental issues. A reduction process is often needed to activate these catalysts. However, there is a lack of techniques to accurately control this process, thus the chemical composition of the catalysts is usually unclear. Ni‐based catalysts are among the most commonly used due to their effectiveness and low costs. In this work, we use the reduction of a Ni/Al2O3 catalyst used in dry reforming of methane to demonstrate a novel technique that well controls the reduction extent of metal catalysts. We achieve this goal by using IR spectroscopy to monitor and quantify the reduction product, H2O, in the process. Specifically, we measure a full and a partial H2O production kinetics, and subsequently develop an algorithm to control the reduction extent of the Ni catalyst in a wide range. This algorithm is proved effective. The technique can be applied generally to any pretreatment process that involves IR measurable gases and its wide application would greatly promote the fundamental catalyst structure‐performance investigation.
Au@gap@AuAg Nanorod Side‐by‐Side Assemblies for Ultrasensitive SERS Detection of Mercury and its Transformation

Published: May 2019

AbstractAs one of the most toxic heavy metal elements, mercury ion (Hg2+) and its methylated product, methylmercury (MeHg) can pose a threat to human health and the environment. Herein, a novel Raman biosensor with cascade sensitivity is developed for Hg2+ detection through Au@gap@AuAg nanorod side‐by‐side assemblies. Due to the strong electromagnetic coupling from the assemblies and core–shell structure, the Raman sensor possesses high sensitivity with the limit of detection (LOD) of 0.001 ng mL‐1, which is about one order lower than traditional atomic fluorescence spectrometer (AFS) methods. Moreover, the fabricated biosensor is used to measure residual mercury levels in tissues and eggs of hens fed high‐mercury diets, and the results show total mercury in collected egg yolks is 20 times higher than whites. Furthermore, the form of mercury in the eggs is also analyzed by high‐performance liquid chromatography coupled with AFS, and, unexpectedly, the methylated product MeHg tends to only be found in egg whites. These interesting differences may indicate a new research direction for the toxicity of mercury in living organisms, and the developed ultrasensitive Surface Enhanced Raman Scattering (SERS) method could pave a broad way for the application of biosensors in Hg detection.
Transformation towards agile software product line engineering in large companies: A literature review
Authors: Klünder Jil Ann‐Christin , Hohl Philipp , Prenner Nils , Schneider Kurt 
Published: May 2019

AbstractAlmost all companies struggle with software systems that are getting increasingly complex. Therefore, in particular large companies often use software product lines, which provide an efficient way to manage software reuse as well as the high complexity. However, software product lines seem to be too slow to react to changes. Agile development approaches promise to meet this demand. At the same time, integrating an agile approach is not always easy. Consequently, there is a need for a transformation model that supports the agile transformation without harming the benefits of software product lines.In this paper, we present the results of a literature review regarding agile transformation in large software companies. Our results summarize the insights from 85 papers and present a list of 20 tasks and tasks that are recommended by several researchers to be considered during the transformation. On the basis of these results, we create an agile transformation model—the so‐called “agile hamburger”—that contains these tasks and preserves software product lines. Since the model is rather coarse grained and generic, we also support the adaption to different teams by presenting an assessment model tailored to the demands of the automotive domain.

Published: May 2019

SummarySmartphone and automotive technologies are rapidly converging, letting drivers enjoy communication and infotainment facilities and monitor in‐vehicle functionalities, via on‐board diagnostics (OBD) technology. Among the various automotive apps available in playstores, Android Auto infotainment and OBD‐II apps are widely used and are the most popular choice for smartphone to car interaction. Automotive apps have the potential of turning cars into smartphones on wheels but can be also the gateway of attacks. This paper defines a static analysis that identifies potential security risks in Android infotainment and OBD‐II apps. It identifies a set of potential security threats and presents an actual static analyzer for such apps. It has been applied to most of the highly rated infotainment apps available in the Google Play store, as well as on the available open‐source OBD‐II apps, against a set of possible exposure scenarios. Results show that almost 60% of such apps are potentially vulnerable and that 25% pose security threats related to the execution of JavaScript. The analysis of the OBD‐II apps shows possibilities of severe controller area network injections and privacy violations, because of leaks of sensitive information.
