Improved method for removing siderite byin situacidification before elemental and isotope analysis of soil organic carbon
Authors: Vindušková Olga , Jandová Kateřina , Frouz Jan 
Published: November 2018

AbstractSiderite (FeCO3) is an iron carbonate mineral commonly found in sediments and soils. Similarly to other carbonates, such as calcite or dolomite, it may substantially affect the quantification of organic carbon (C) as well as determination of C isotope ratio of soil organic matter. Both analyses require effective removal of siderite by pretreatment with acid. However, little is known about the siderite removal efficiency of the acid pretreatment methods which have been previously proposed in the literature.In our study, we tested three previously proposed carbonate removal methods for siderite removal in siderite‐containing soils. Furthermore, we tested whether siderite C content in a soil sample can be detected as CO2evolved after H3PO4addition which would allow organic C determination from the difference between total and inorganic C.None of the three tested pretreatment methods led to sufficient removal of siderite C when applied on siderite alone. Therefore, we developed a new protocol for a 4‐day treatment with 10% HCl at 25°C. At siderite content of up to 10 wt.%, the removal efficiency of our method (99–100%) was sufficient both for organic C as well as for C isotope analyses. This was further confirmed with tests on siderite‐containing soils. These showed that the method ofLarsonet al. () developed for sediments is also suitable. However, the new protocol provides advantage in terms of less microplate manipulation, capsule overflow and oven use. We found that CO2is not evolved 2 minutes after H3PO4addition from siderite in contrast to calcite and dolomite. This fact can be used for separate quantification of inorganic C from calcite/dolomite and siderite,e.g., in studies of their different role in soil development. We showed that siderite‐containing soils require special pretreatment procedure before organic C and13C/12C analyses. We recommend using our protocol if techniques such as XRD or SEM‐EDS indicate the presence of siderite in soil.
Recent developments and applications of capillary and microchip electrophoresis in proteomics and peptidomics (2015–mid 2018)

Published: November 2018

AbstractThis review summarizes recent developments and applications of capillary and microchip electroseparation methods in proteomic and peptidomic analyses since the year 2015 to ca. mid 2018. Sample preparation procedures for the removal of interfering components or for pre‐fractionation and preconcentration of proteins and peptides of interest are discussed. The innovations in coupling of capillary or microchip electroseparation methods with different modes of mass spectrometry detection are covered. In addition, significant recent applications of capillary electromigration methods in both bottom‐up and top‐down proteomics as well as in determinations of post‐translational modifications of proteins are presented. Moreover, several examples of the utilization of capillary electromigration methods coupled with mass spectrometry detection for clinical proteomics and peptidomics are described.

ABSTRACTOn average, band recovery rates of adult black brant (Branta bernicla nigricans) more than doubled between the 2000s and 2010s. However, the spatial distribution of band recoveries of black brant has not been reported. Our objective was to describe the spatial distribution of band recoveries of black brant since 1990. We found that Alaska, California, and Mexico accounted for ≥89% of band recoveries for black brant released from the Arctic and the Tutakoke River Colony in southwestern Alaska, in each decade studied. Although recovery rates increased in each major harvest region from the 1990s to 2010s, increases were not even. For brant released from the Arctic, the recovery rate in Alaska has gone up 7‐fold, whereas the recovery rate in Mexico has increased 1.3‐fold since the 1990s. For brant banded in the Arctic, the increased recovery rates in Alaska resulted largely from a rise in recoveries from the Izembek Lagoon area. For brant banded at the Tutakoke River Colony, the recovery rate in Alaska increased 4.8‐fold, whereas recovery rates in Mexico increased 1.6‐fold. Despite the reduced relative contribution of Mexico to band recoveries in the 2010s, Bahia San Quintin, Mexico, still contributes more recoveries than any other wintering estuary. Because 57–60% of black brant band recoveries occur at the localities of Izembek Lagoon, Alaska; Humboldt Bay, California; and Bahia San Quintin, it is likely that accurate annual estimates of the black brant population using Lincoln's method could be derived from hunter bag checks at these 3 areas. If population managers are interested in managing harvest rates of black brant, they could focus efforts on the main hunting areas we highlight in this paper. Finally, it is unclear if the recent increases in band recovery rates are the result of increased harvest, a declining population, or both; therefore, we suggest refinement of population monitoring programs and continued monitoring of band recovery rates. © 2018 The Wildlife Society.
Coherent full duplex radio over fiber system with multiple signal transmission
Authors: Chandrasenan Archa , Zacharias Joseph 
Published: November 2018

AbstractIn this paper, a cost‐effective and simple full duplex RoF (radio over fiber) system is developed from a simplex coherent RoF. At the transmitter, utilizing the magnitude and phase of the vector carrier, four different information are encoded simultaneously on the carrier light wave. Dividing the total carrier power into two branches, enable the transmitter to modulate two distinct information on each branch. The working of the system is described in two main sections namely uplink section and downlink section. In the first section, encoding of uplink transmitting information and decoding downlink information at the central office (CO) is described. In the second section, modulating downlink transmitting information and demodulating coherently the uplink receiving information at the base station (BS) are described. An algorithm based on fast Fourier transform is described for effectively canceling the phase noise (PN) at the BS. Considering the cost of optical components, the source used to coherently detect the uplinked transmitted information, is again used as the carrier for downlink. Altogether, this system enables to transmit three different information on uplink and are faithfully received at the BS with an average of log(BER) value −23 dB. And for downlink, one information is transmitted and is successfully received at the CO with log(BER) of −9 dB. About 10 dB decrease in log(BER) values was found after the cancellation of PN.

ABSTRACTIntroduction: Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are considered part of the same pathological spectrum. There is an increased risk of ALS in patients who have had melanoma. The risk of FTLD in melanoma (or cancer) patients is unknown. We aimed to study if C9ORF72 expansion is linked to a higher prevalence of melanoma. Methods: We selected patients with a diagnosis in the ALS‐FTLD spectrum who were tested for pathogenic mutations. Medical history was reviewed, to identify those with pathologically documented melanomas. Results: We included 189 patients. Sixty‐two had identified pathogenic mutations (39 C9ORF72). C9ORF72 carriers had a significantly higher risk of melanoma (odds ratio = 24.709; P < 0.007). There was no association with phenotype. Conclusions: These findings suggest that patients with a history of melanoma may have an increased probability of carrying a C9ORF72 repeat expansion. ALS or FTLD carriers of C9ORF72 should undergo surveillance for skin changes. Muscle Nerve 59:362–365, 2019

1H‐MRS enables non‐invasive detection of 2‐hydroxyglutarate (2‐HG), an oncometabolite accumulating in gliomas carrying mutations in the isocitrate dehydrogenase (IDH) genes. Reliable 2‐HG quantitation requires reproducible post‐processing, deployment of fitting algorithms and quantitation methods. We prospectively enrolled 38 patients with suspected or recently diagnosed gliomas (IDH mutated n = 26). The MRI protocol included a 1H single voxel PRESS sequence with volumes of usually 8 mL or more (20 × 20 × 20 mm3) at TE = 97 ms and 180° pulse spacing. Our aim was to evaluate the reliability of 2‐HG quantitation comparing two frequently used software tools and their respective options of baseline correction (jMRUI with the time domain methods AQSES and QUEST, and LCModel, which analyzes the frequency domain data). For AQSES, degrees of freedom for baseline correction constrains were varied. For LCModel, baseline correction was obtained with and without correction of the unknown background term (predefined macromolecules, lipids). Tissue concentrations were calculated based on the phantom replacement method. Quantitation of 2‐HG levels showed similar mean 2‐HG tissue concentrations for IDH mutated tumors (2.65mM, range 3.06–2.20) for all methods. Bland–Altman plots (difference plots) did not reveal a systematic bias (fixed bias) for any of the algorithms tested, and we were able to show a significant correlation regarding 2‐HG concentration at the same echo time with few statistical outliers (parametric correlation). However, evaluation of outliers suggested that in vivo quantitation of 2‐HG is affected not only by the fitting domain (time or frequency), but also by the baseline correction, which is a major contributing factor to the result of 2‐HG fitting. Clinical application of 2‐HG quantitation as a prognostic or predictive biomarker, particularly in multicenter trials, requires standardized use of fitting methods and baseline correction procedures.
Designing Self‐Assembled Rosettes: Why Ammeline is a Superior Building Block to Melamine
Authors: Petelski Andre Nicolai , Fonseca Guerra Célia 
Published: November 2018

AbstractIn supramolecular chemistry, the rational design of self‐assembled systems remains a challenge. Herein, hydrogen‐bonded rosettes of melamine and ammeline have been theoretically examined by using dispersion‐corrected density functional theory (DFT‐D). Our bonding analyses, based on quantitative Kohn–Sham molecular orbital theory and corresponding energy decomposition analyses (EDA), show that ammeline is a much better building block than melamine for the fabrication of cyclic complexes based on hydrogen bonds. This superior capacity is explained by both stronger hydrogen bonding and the occurrence of a strong synergy.
Influence of biodegradation on crystallization of poly (butylene adipate‐co‐terephthalate)
Authors: Svoboda Petr , Dvorackova Marie , Svobodova Dagmar 
Published: November 2018

The biodegradation of aromatic‐aliphatic biodegradable polyester poly (butylene adipate‐co‐terephthalate) (PBAT) was studied under mesophilic (37°C) and thermophilic (55°C) anaerobic conditions. Anaerobic sludge from municipal wastewater treatment plant was utilized as an inoculum. Non‐isothermal crystallization kinetics of PBAT before and after biodegradation was explored by differential scanning calorimetry. Under mesophilic anaerobic conditions (37°C), the biodegradation after 126 days was only 2.2%, molecular weight changed from 93 000 to 25 500 g/mol, and the crystallization behavior was changed only slightly. However, biodegradation under thermophilic anaerobic conditions (55°C) caused much bigger changes: biodegradation according to biogas production reached after 126 days 8.3%, molecular weight changed from 93 000 to 9430 g/mol, and the crystallization behavior was changed significantly. While Tm increased only slightly, Tc on the other hand increased significantly for the sample after biodegradation at 55°C. Also, the crystallization rate was slower (particularly at lower cooling rates), but crystallinity was slightly higher. The diffraction pattern was observed by X‐ray diffraction.

Abstract
Human induced pluripotent stem cells (hiPSCs) are an important tool for research and regenerative medicine, but their efficient cryopreservation remains a major challenge. The current gold standard is slow-rate freezing of dissociated colonies in suspension, but low recovery rates limit immediate post-thawing applicability. We tested whether ultrafast cooling by adherent vitrification improves post-thawing survival in a selection of hiPSCs and small molecule neural precursor cells (smNPCs) from Parkinson’s disease and controls. In a dual-center study, we compared the results by immunocytochemistry (ICC), fluorescence-activated cell sorting analysis, and RNA-sequencing (RNA-seq). Adherent vitrification was achieved in the so-called TWIST substrate, a device combining cultivation, vitrification, storage, and post-thawing cultivation. Adherent vitrification resulted in preserved confluency and significantly higher cell numbers, and viability at day 1 after thawing, while results were not significantly different at day 4 after thawing. RNA-seq and ICC of hiPSCs revealed no change in gene expression and pluripotency markers, indicating that physical damage of slow-rate freezing disrupts cellular membranes. Scanning electron microscopy showed preserved colony integrity by adherent vitrification. Experiments using smNPCs demonstrated that adherent vitrification is also applicable to neural derivatives of hiPSCs. Our data suggest that, compared to the state-of-the-art slow-rate freezing in suspension, adherent vitrification is an improved cryopreservation technique for hiPSCs and derivatives.

Tourism, Nation-Building, and Magazines
Authors: Lindsay Claire 
Published: November 2018

AbstractIn two sections, this chapter examines, first, the correspondence between tourism and nation-building in conceptual and material terms and, second, the magazine as a paradigmatic expression in print culture of that concurrence. The first section, drawing on recent scholarship in tourism and Latin American studies, situates the book’s focus on Mexico within the country’s remarkable emergence from the Revolution during the 1920s and onwards, contextualizing that significant juncture within the history of organized tourism there since the late nineteenth century to the present day. The second section, drawing on examples from the book’s corpus of magazines, elucidates the unparalleled properties of the periodical as an object of study within those contexts and considers ensuing methodological issues.
Mapping Capital in Mexico This Month (1955–1971)
Authors: Lindsay Claire 
Published: November 2018

AbstractThis chapter, based on original archival work on Mexico/This Month, responds to Susannah Glusker’s invitation to undertake ‘an analysis of [its] contribution … in promoting Mexico’ (Glusker 1998: 15), with a particular focus on cartography and capital. The chapter, through a close reading of its trademark Explorers’ Maps series, and drawing on pertinent work on cartography from a range of disciplines, suggests that Mexico This Month visually and discursively mapped a fantasy of capital that is related to, yet destabilized by, a second, more problematic fantasy of conquest. The chapter also enquires into the impact of capital on the magazine’s external periodical code, that is, the relation between the conditions of its state funding and its endurance as a material artifact over its lifetime.
Genes Encoding Mammalian Oviductal Proteins Involved in Fertilization are Subjected to Gene Death and Positive Selection

Published: November 2018

AbstractOviductal proteins play an important role in mammalian fertilization, as proteins from seminal fluid. However, in contrast with the latter, their phylogenetic evolution has been poorly studied. Our objective was to study in 16 mammals the evolution of 16 genes that encode oviductal proteins involved in at least one of the following steps: (1) sperm–oviduct interaction, (2) acrosome reaction, and/or (3) sperm–zona pellucida interaction. Most genes were present in all studied mammals. However, some genes were lost along the evolution of mammals and found as pseudogenes: annexin A5 (ANXA5) and deleted in malignant brain tumor 1 (DMBT1) in tarsier; oviductin (OVGP1) in megabat; and probably progestagen-associated endometrial protein (PAEP) in tarsier, mouse, rat, rabbit, dolphin, and megabat; prostaglandin D2 synthase (PTGDS) in microbat; and plasminogen (PLG) in megabat. Four genes [ANXA1, ANXA4, ANXA5, and heat shock 70 kDa protein 5 (HSPA5)] showed branch-site positive selection, whereas for seven genes [ANXA2, lactotransferrin (LTF), OVGP1, PLG, S100 calcium-binding protein A11 (S100A11), Sperm adhesion molecule 1 (SPAM1), and osteopontin (SPP1)] branch-site model and model-site positive selection were observed. These results strongly suggest that genes encoding oviductal proteins that are known to be important for gamete fertilization are subjected to positive selection during evolution, as numerous genes encoding proteins from mammalian seminal fluid. This suggests that such a rapid evolution may have as a consequence that two isolated populations become separate species more rapidly.
GPU-warp based finite element matrices generation and assembly using coloring method
Authors: Kiran Utpal , Sharma Deepak , Gautam Sachin Singh 
Published: November 2018

Abstract
Finite element method has been successfully implemented on the graphics processing units to achieve a significant reduction in simulation time. In this paper, new strategies for the finite element matrix generation including numerical integration and assembly are proposed by using a warp per element for a given mesh. These strategies are developed using the well-known coloring method. The proposed strategies use a specialized algorithm to realize fine-grain parallelism and efficient use of on-chip memory resources. The warp shuffle feature of Compute Unified Device Architecture (CUDA) is used to accelerate numerical integration. The evaluation of elemental stiffness matrix is further optimized by adopting a partial parallel implementation of numerical integration. Performance evaluations of the proposed strategies are done for three-dimensional elasticity problem using the 8-noded hexahedral elements with three degrees of freedom per node. We obtain a speedup of up to 8.2× over the coloring based assembly by element strategy (using a single thread per element) on NVIDIA Tesla K40 GPU. Also, the proposed strategies achieve better arithmetic throughput and bandwidth.
Highlights CUDA Warp based strategies for FE matrix generation and assembly. Performed using coloring method and on linear hexahedral element meshing in 3D. Obtained speedup of 5.17×− 8.2× over single thread per element strategy on GPU. Strategies showed better arithmetic throughput and bandwidth through code profiling.
Developing a Comprehensive Trauma- and Resiliency- Focused Program After Superstorm Sandy in New York City

Published: November 2018

ABSTRACTTo contribute to the ongoing discourse about successful programming supporting intermediate behavioral and mental health needs of vulnerable communities affected by disaster, this article presents the Children’s Health Fund (CHF) Sandy Recovery and Resiliency Program as a descriptive case study for a multifaceted, community-based approach to building resiliency, coping, and socioemotional skills in an underserved community in New York City that was affected by Superstorm Sandy. The case study involves retrospective review and analysis of qualitative and quantitative data that were collected as part of routine care and program implementation. From the analysis emerged a program consisting of 3 components: (1) delivery of workshops and community events to decrease stigma and build community-wide resilience, (2) delivery of workshops for students and educators in the local school to increase coping skills as well as referrals to clinical mental health care, and (3) provision of mental health care via a mobile mental health clinic. As a result, we found that following periods of excessive trauma, children and families require a broad-based approach to mental health support. Additionally, the use of the mobile clinic abated most common access barriers and served as a proxy of the concern of the organization for the community.

Published: November 2018

ABSTRACTThe question under discussion is whether the dates of the Late Bronze (LBIIB)-LBIII (Iron IA) transitions in three sites in the southern Levant, namely Megiddo, Tell es-Safi/Gath and Qubur el-Walaydah occur at the same time, as has been proposed by Israel Finkelstein in his article in 2016 in Egypt and Levant. Here we respond to Finkelstein’s comments. We add some new data, clarify the issues that were raised, and conclude that the Late Bronze (LBIIB)-LBIII (Iron IA) transitions occurred at different times in northern and southern Israel.
New insight into the diagnostic cut-off value of serum anti-ToxocaraIgG for ocular toxocariasis in uveitis patients

Published: November 2018

AbstractUveitis is one of the commonest causes of vision loss worldwide and its exact etiology is still not clarified in most patients. The current study is a trial to assess the efficacy of serum anti-Toxocaraimmunoglobulin G (IgG) by enzyme-linked immunosorbent assay (ELISA) as a diagnostic tool for ocular toxocariasis (OT) and to detect OT prevalence and the associated ocular manifestations in sera of patients with uveitis. One hundred and twelve patients (62 females and 50 males) with uveitis were diagnosed by ophthalmologists, radiologists and rheumatologists according to ocular manifestations, laboratory and radiological investigations. Serum anti-ToxocaraIgG titers were determined by ELISA in sera of all patients. Our results revealed that OT is highly associated with intermediate and posterior uveitis. Children and young adult females, especially those residing in rural areas, complained mainly of diminution of vision in the left eye, with strabismus and leukocoria. At a cut-off value of 0.258, the sensitivity and specificity of IgG ELISA were 93.3% and 100%, respectively. In conclusion, at a novel cut-off value of 0.258 the serum anti-ToxocaraIgG ELISA is predicted to be a diagnostic tool for OT regarding sensitivity and specificity. Also, it has potential importance in the interpretation and differential diagnosis of OT. Thus, serum anti-ToxocaraIgG ELISA should be a routine test for screening of suspected cases.
