Published: August 2018

Abstract
Close binaries of supermassive black holes (CB-SMBHs) with separations of ≲0.1 pc as the final stage of galaxy mergers are sources of low-frequency gravitational waves; however, they are still elusive observationally because they are not spatially resolved. Fortunately, reverberation as echoes of broad emission lines to ionizing continuum conveys invaluable information on the dynamics of broad-line regions (BLRs) governed by SMBHs in the central regions of active galactic nuclei (AGNs). In this paper, we demonstrate how to compose the hybrid two-dimensional transfer functions (TFs) of binary BLRs around the CB-SMBHs in AGNs, providing an opportunity for identifying them from reverberation mapping (RM) data. It is found that there are variation-coupling effects in the TFs arising from the coupling of CB-SMBH light curves in the Fourier space. We provide semi-analytical formulations of the TFs for kinematic maps of the gas. For cases with the simplest variation-coupling effects, we make calculations for several BLR models and reveal significant distinctions from those of single active black holes. In principle, the difference is caused by the orbital motion of the CB-SMBH systems. In order to search for CB-SMBHs in time-domain space, selection of target candidates should focus on local AGNs with Hβ double-peaked profiles and weaker near-infrared emission. High-fidelity RM campaigns of monitoring the targets in future will provide opportunities to reveal these kinematic signatures of the CB-SMBHs and hence measurements of their orbital parameters.

Abstract
Nova SMC 2016 has been the most luminous nova known in the direction of the Magellanic Clouds. It turned into a very luminous supersoft X-ray source between days 16 and 28 after the optical maximum. We observed it with Chandra, the HRC-S camera, and the Low Energy Transmission Grating on 2016 November and 2017 January (days 39 and 88 after optical maximum), and with XMM-Newton on 2016 December (day 75). We detected the compact white dwarf (WD) spectrum as a luminous supersoft X-ray continuum with deep absorption features of carbon, nitrogen, magnesium, calcium, probably argon, and sulfur on day 39, and oxygen, nitrogen, and carbon on days 75 and 88. The spectral features attributed to the WD atmosphere are all blueshifted, by about 1800 km s−1 on day 39 and up to 2100 km s−1 in the following observations. Spectral lines attributed to low-ionization potential transitions in the interstellar medium are also observed. Assuming the distance to the Small Magellanic Cloud, the bolometric luminosity exceeded the Eddington level for at least three months. A preliminary analysis with atmospheric models indicates an effective temperature of around 700,000 K on day 39, peaking at the later dates in the 850,000–900,000 K range, as expected for a ≃1.25 M
⊙ WD. We suggest a possible classification as an oxygen–neon WD, but more precise modeling is needed to accurately determine the abundances. The X-ray light curves show a large, aperiodic flux variability, which is not associated with spectral variability. We detected red noise, but did not find periodic or quasiperiodic modulations.

The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within available resources to assess all known species. In such cases, a random sample of species might be selected for assessment and the results derived from it extrapolated for the entire group - the Sampled Red List Index (SRLI). The current contribution is the third in four papers that will constitute the baseline of a future spider SRLI encompassing 200 species distributed across the world.
A sample of 200 species of spiders were randomly selected from the World Spider Catalogue, an updated global database containing all recognized species names for the group. The 200 selected species where divided taxonomically at the family level, and the familes were ordered alphabetically. In this publication, we present the conservation profiles of 58 species belonging to the famillies alphabetically arranged between Oecobiidae and Salticidae, which encompassed Oecobiidae, Oonopidae, Orsolobidae, Oxyopidae, Palpimanidae, Philodromidae, Pholcidae, Pisauridae, Prodidomidae and Salticidae.

Published: August 2018

Abstract
Background: Because of its chemical complexity, the estimation of dietary fiber content of feed and food materials is a difficult analytical challenge. Three major fiber analyses are conducted routinely in the United States including crude fiber (CF), detergent fiber, and total dietary fiber (TDF). Objective: Factors crucial to the successful measurement of dietary fibers are described and suggestions provided as to how to overcome potential analytical problems within assays. Methods: An accounting of methodological details that result in variation in fiber concentration values is presented along with suggestions as to how to decrease the variation. Results: CF analysis remains in use in the livestock feed and pet food industries for nutrition labeling purposes in spite of the fact that the analysis does not separate mammalian enzyme-digestible from indigestible carbohydrate components, and values obtained are usually 30–50% of the actual dietary fiber concentration. Detergent fiber methods quantify the insoluble dietary fibers (IDF) accurately, but not the soluble dietary fiber (SDF) components. TDF methods account for intrinsic and intact fibers, isolated and extracted fibers, and synthetic fibers found in feed and food ingredients and complete diet matrixes. Conclusions: The CF procedure should be abandoned as it fails to quantify fiber properly. Detergent analyses quantify IDF. TDF methods quantify both IDF and SDF. Highlights: Accurate dietary fiber quantification is essential given the role of fiber in health and well-being of animals and humans.

Published: August 2018

Colon is the oldest street in the Philippines. It used to be the center of trade and commerce decades ago. The study aimed to determine the vendor demographics and the positive and adverse effects of the city government-organized Colon Night Market Program on the night market vendors in Cebu City, Philippines. Impact Value Chain and Social Return on Investment Method Analysis were used. Two survey questionnaires were prepared: one administered to the vendors that benefited the night market program, and another set was conducted to the customers. The results were validated by in-depth interviews. The study discovered that Muslim-Filipino vendors constituted the group of vendors with the highest proportion while the homegrown Cebuanos constituted the least number. The affirmative effects of the program were identified: better income and improved quality of life for the individuals, creation of more jobs, an offering of better deals and lower price, and the building of camaraderie among vendors. There were also a few negative issues identified. It was also discovered that there is $6.44 dollars for every one dollar invested by the government. It is recommended that the program is operated year-round to achieve a higher return on investment.

Communication is immensely dynamic in the 21st century as evidenced by the fast-changing communication mechanisms. However, global trends show that oral communication skills are still considered among the most desired skills that employers are seeking in the workplace. Thus, there is a need to explore the manifestation of the socio-cultural components of the personnel, namely: behavior, attitude, and etiquette in their oral communication practices particularly the informal manner, as the components bear a significance when they engage in such form of communication interaction. Direct observations of thirty-eight episodes of the teaching and non-teaching interactions of the personnel were noted followed by a Focus Group Discussion with seven selected personnel that validated the results of the observed manifestation of their socio-cultural components and likewise explored other underlying factors that shaped and developed their socio-cultural components. Behavior (facial expressions) and etiquette (voice tone) components mainly dominated in their interactions, yet the attitude component is also significant to them. The manifestation of these components is situational given their respective upbringing during childhood as a major perceived aspect that established these components. A desirable manifestation of these components is encouraged when engaging in informal oral communication interactions so to become a competent communicator in the workplace.
Validity of Astronomical Calculation in Determining the Lunar Month
Authors: Umpa Aleem Morad 
Published: August 2018

Astronomical calculations, in the view of the majority of jurists, rest on mere assumptions and are hypothetical in nature. Therefore, significant acts of worship such as the beginning and end of the month of Ramadhan cannot be determined by calculations. The study aimed to validate the astronomical calculation in determining the beginning of new lunar month in connection with Islamic acts of worship. The study utilized descriptive and qualitative research method through in-depth study of printed and internet sources. Results showed that sighting and calculations are complementary and both are needed. Calculations to negate false sighting is used, but not to completely replace sighting. Thus, if the calculations say with certainty that Hilal cannot be visible, then we should reject or negate the false sighting and reduce errors. Since astronomical calculations, especially on the birth of new Moon, are absolutely precise, the claim that a consensus exists among all the Muslim jurists regarding absolute mistrust of astronomical calculations, in all forms and ways, related to the beginning and ending of the Islamic months are unfounded, though the majority adopted that opinion because of the uncertainties connected with calculations in their times. Although calculations alone cannot be used to determine the start of the new lunar month, this does not mean that we should disregard it.

Published: August 2018

Ly6/urokinase‐type plasminogen activator receptor (uPAR) (LU) domain containing 6 (LYPD6) is a Wnt signaling enhancer that promotes phosphorylation of the Wnt coreceptor low density lipoprotein receptor‐related protein 6 (LRP6). It also binds the nicotinic acetylcholine receptor (nAChR). We report here the 1.25 Å resolution structure of the LYPD6 extracellular LU domain and map its interaction with LRP6 by mutagenesis and surface plasmon resonance. The LYPD6LU structure reveals a ‘trifingered protein domain’ fold with the middle fingertip bearing an ‘NxI’ motif, a tripeptide motif associated with LRP5/6 binding by Wnt inhibitors. Of the Ly6 protein family members, only LYPD6 has an NxI motif. Since mutations in the LYPD6 NxI motif abolish or severely reduce interaction with LRP6, our results indicate its key role in the interaction of LYPD6 with LRP6.
Molecular Engineering of Host Materials for High‐Performance Phosphorescent OLEDs: Zig‐Zag Conformation with 3D Gridding Packing Mode Facilitating Charge Balance and Quench Suppression
Authors: Wang Fang , Liu Di , Li Jiuyan , Ma Mengyao 
Published: August 2018

AbstractA group of bipyridine/carbazole hybrid compounds, namely m‐BPyDCz, p‐BPyDCz, m‐BPySCz, and p‐BPySCz, are designed and developed as host materials for phosphorescent organic light‐emitting diodes (PhOLEDs). By tuning the p/n molar ratio and para‐/meta‐ substitution style, scorpion‐, Y‐, Z‐, and L‐shape molecular conformations are generated. In virtue of intermolecular hydrogen bonds and π–π interaction, these compounds form different molecular packing patterns in their single crystals. Particularly the Z‐shaped m‐BPySCz achieves 3D gridding packing with regular and ordered carbazole and pyridine columns as carrier hoping channels and larger intermolecular distance, which not only guarantees charge balance but also suppresses exciton quenching. Consequently the m‐BPySCz hosted sky‐blue and green PhOLEDs exhibit high external quantum efficiencies of 27.3% and 28.0% and low efficiency roll‐offs of 8.1% (at brightness of 1000 cd m−2 for blue) and 14.3% (at 10000 cd m−2 for green), all superior to other analogs and many reported host materials. The excellent performance of m‐BPySCz versus its lowest molecular weight and lowest amorphous stability manifests that the molecular packing style of host material dominates to determine the overall performance of PhOLEDs and the 3D gridding packing mode of zig‐zag conformation may be one ideal strategy to eliminate efficiency roll‐off in PhOLEDs.

AbstractReal‐time and continuous monitoring of physiological signals is essential for mobile health, which is becoming a popular tool for efficient and convenient medical services. Here, an active pulse sensing system that can detect the weak vibration patterns of the human radial artery is constructed with a sandwich‐structure piezoelectret that has high equivalent piezoelectricity. The high precision and stability of the system result in possible medical assessment applications, including the capability to identify common heart problems (such as arrhythmia); the feasibility to conduct pulse palpation measurements similar to well‐trained doctors in Traditional Chinese Medicine; and the possibility to measure and read blood pressure.

AbstractA 3D pomegranate‐like “Ag nanoparticle clusters/CuO nanowires” heterostructure is designed and prepared by a fast two‐step method with assistance of capillarity in this paper. Owing to the abundant “hot spots” generated in the gaps of Ag nanoparticle clusters and the improved electromagnetic mechanism caused by the charge transfer effect between Ag/CuO interface, this heterostructure shows outstanding Raman performance with the enhancement factor as high as 3.30 × 109. Both the formation process and the Raman enhancement mechanism of this heterostructure are meticulously analyzed, and the finite‐different time‐domain and first‐principles simulations are also introduced here to further verify some conjectures. Moreover, this heterostructure shows a certain level of crock resistance, which endows the base a well durability. This paper provides a fast and dexterous way in preparing low‐cost and high‐sensitivity surface enhanced Raman scattering (SERS)‐active substrate, which will show promising applications in chemical or biological detection.

ObjectiveThe basis for clinical variation related to underlying progressive supranuclear palsy (PSP) pathology is unknown. We performed a genome‐wide association study (GWAS) to identify genetic determinants of PSP phenotype.MethodsTwo independent pathological and clinically diagnosed PSP cohorts were genotyped and phenotyped to create Richardson syndrome (RS) and non‐RS groups. We carried out separate logistic regression GWASs to compare RS and non‐RS groups and then combined datasets to carry out a whole cohort analysis (RS = 367, non‐RS = 130). We validated our findings in a third cohort by referring to data from 100 deeply phenotyped cases from a recent GWAS. We assessed the expression/coexpression patterns of our identified genes and used our data to carry out gene‐based association testing.ResultsOur lead single nucleotide polymorphism (SNP), rs564309, showed an association signal in both cohorts, reaching genome‐wide significance in our whole cohort analysis (odds ratio = 5.5, 95% confidence interval = 3.2–10.0, p = 1.7 × 10−9). rs564309 is an intronic variant of the tripartite motif‐containing protein 11 (TRIM11) gene, a component of the ubiquitin proteasome system (UPS). In our third cohort, minor allele frequencies of surrogate SNPs in high linkage disequilibrium with rs564309 replicated our findings. Gene‐based association testing confirmed an association signal at TRIM11. We found that TRIM11 is predominantly expressed neuronally, in the cerebellum and basal ganglia.InterpretationOur study suggests that the TRIM11 locus is a genetic modifier of PSP phenotype and potentially adds further evidence for the UPS having a key role in tau pathology, therefore representing a target for disease‐modifying therapies.

Published: August 2018

AbstractThe catalytic asymmetric construction of silicon‐stereogenic silanes is of great interest and significance, but has met with only limited success to date. We herein report the enantioselective hydrosilylation of alkenes with dihydrosilanes by a chiral half‐sandwich scandium catalyst, which constitutes an efficient and general route for the synthesis of a wide range of enantioenriched silicon‐stereogenic silanes from easily accessible starting materials. This reaction features a broad substrate scope, high yields, and high enantioselectivity. Some of the chiral tertiary silane products were also converted into valuable derivatives, such as chiral silanol, quaternary silane, and benzosilole compounds.
Patient Care During Minimally Invasive Lateral Spine Surgery
Authors: Dufault Caroline A. 
Published: August 2018

AbstractPerioperative nurses care for patients undergoing a wide range of surgical procedures. One fast‐growing surgical specialty is spine surgery performed using minimally invasive techniques. Patients may be candidates for minimally invasive spine surgery based on their presenting signs and symptoms and medical imaging test results. Open anterior and posterior surgical approaches to spine surgery are how surgeons traditionally have performed these procedures. However, new technology has enabled a minimally invasive lateral approach to the spine. This approach minimizes many of the risks and challenges associated with both the anterior and posterior approaches. Minimally invasive lateral interbody fusion requires the perioperative nurse to have a thorough understanding of the necessary patient positioning, spinal anatomy, and OR suite setup to ensure a safe and successful surgical experience for the patient.
Inactivating NADH:quinone oxidoreductases affects the growth and metabolism of Klebsiella pneumoniae

Published: August 2018

AbstractNADH:quinone oxidoreductases (NQOs) act as the electron entry sites in bacterial respiration and oxidize intracellular NADH that is essential for the synthesis of numerous molecules. Klebsiella pneumoniae contains three NQOs (NDH‐1, NDH‐2, and NQR). The effects of inactivating these NQOs, separately and together, on cell metabolism were investigated under different culture conditions. Defective growth was evident in NDH‐1‐NDH‐2 double and NDH‐1‐NDH‐2‐NQR triple deficient mutants, which was probably due to damage to the respiratory chain. The results also showed that K. pneumoniae can flexibly use NQOs to maintain normal growth in single NQO‐deficient mutants. And more interestingly, under aerobic conditions, inactivating NDH‐1 resulted in a high intracellular NADH:NAD+ ratio, which was proven to be beneficial for 2,3‐butanediol production. Compared with the parent strain, 2,3‐butanediol production by the NDH‐1‐deficient mutant was increased by 46% and 62% in glycerol‐ and glucose‐based media, respectively. Thus, our findings provide a practical strategy for metabolic engineering of respiratory chains to promote the biosynthesis of 2,3‐butanediol in K. pneumoniae.
Two‐Dimensional Metal‐Organic Framework Nanosheets: A Rapidly Growing Class of Versatile Nanomaterials for Gas Separation, MALDI‐TOF Matrix and Biomimetic Applications

Published: August 2018

AbstractTwo‐dimensional (2D) metal‐organic framework (MOF) nanosheets, as an emerging type of 2D materials, attract numerous attention due to their unique properties. First, the ultrathin thickness and nanoscale of the materials results in homogeneous dispersion in aqueous solution, giving the materials more opportunities to be utilized in solution chemistry, especially beneficial to the biomimetic catalysis and bio‐related analytical applications. Second, the large surface area and accessible active sites of the MOF nanosheets are favorable to the binding between materials and the substrate, leading to their superior performance in catalysis, sensing and enzyme inhibition. Third, the suitable sizes of nanopores on the 2D MOF nanosheets give them the abilities to act as membranes for highly selective and energy‐saving gas separation. This minireview covers the synthesis, characterization as well as bio‐related and separation applications of 2D MOF nanosheets.
