Published: October 2019

AbstractBackgroundTransgender and non-binary (TNB) youth face disparities in sexual health risks compared with cisgender peers. Comprehensive sex education programs have the potential to result in delayed sexual debut, increased condom and contraceptive use, and reduced sexual risk-taking; however, little research has explored the specific sex education needs of TNB youth.AimTo use insights from TNB youth, parents of TNB youth, and healthcare affiliates to understand deficits in sex education experienced by TNB youth, and to elicit recommended content for a comprehensive and trans-inclusive sex education curriculum.MethodsWe conducted 21 in-depth interviews with non-minor TNB youth (n = 11) and with parents (n = 5) and healthcare affiliates (n = 5) of TNB youth recruited from Seattle Children’s Gender Clinic and local TNB community listerv readerships. Data was analyzed using theoretical thematic analysis.OutcomesParticipants described prior sex education experiences and content needs of TNB youth.ResultsParticipants described 5 key sources where TNB youth received sexual health information: school curricula, medical practitioners, peers, romantic partners, and online media. Inapplicability of school curricula and variable interactions with medical practitioners led youth to favor the latter sources. 8 content areas were recommended as important in sex education for TNB youth: puberty-related gender dysphoria, non-medical gender-affirming interventions, medical gender-affirming interventions, consent and relationships, sex and desire, sexually transmitted infection prevention, fertility and contraception, and healthcare access.Clinical ImplicationsDependence on potentially inaccurate sex education sources leaves TNB youth vulnerable to negative outcomes, including sexually transmitted infections, pregnancy, unsanitary/unsafe sex toy use, and shame about their body or sexual desires.Strengths & LimitationsStrengths included capturing perspectives of an underserved population using open-ended interview questions, which allowed topics of greatest importance to participants to arise organically. Limitations included a sample size of 21 participants, and racial and geographic homogeneity of youth and parent participants. Only 1 author identifies as TNB. One-on-one interview methods may have omitted participants who would otherwise have been willing to share their perspective in a more impersonal format.ConclusionThis study demonstrates that TNB youth have unique sex education needs that are not well covered in most sexual health curricula. Recommended content for this population includes standard sex education topics that require trans-inclusive framing (eg, contraception), topics specific to TNB youth (eg, gender-affirming medical interventions), and topics absent from standard curricula that warrant universal teaching (eg, information on consent as it relates to sex acts aside from penile-vaginal sex).

Published: October 2019

A 32-year-old male presented to the emergency department for confusion, dyspnea, and a “white out” of his central vision over the preceding 24 hours. The patient had recently consumed a bottle of alcohol purchased overseas. Bloodwork revealed a severe metabolic acidosis (pH 6.90) and a critically high methanol level of 28.9 mmol/l. Shortly after presentation, the patient went into respiratory failure and became comatose. He was intubated and admitted to the ICU.

AbstractEffectively addressing public health crises requires dynamic and nimble interdisciplinary collaborations across the translational spectrum, from bench to clinic to community. The Clinical and Translational Science Award (CTSA) Program hubs are uniquely suited to facilitate interdisciplinary collaborations across universities and academic medical centers. This paper describes the activities at the Columbia University CTSA Program hub to address a current public health crisis, the opioid epidemic. Columbia’s CTSA Program hub led a three-phase approach, based on the Conceptual Model of Transdisciplinary Scientific Collaboration as described by Stokols et al.: (1) a university-wide planning and brainstorming phase to identify key leaders across many domains who are influential in addressing the opioid epidemic, (2) a campus-wide and community outreach to identify all interested parties, and (3) ongoing targeted support for collaboration development. Preliminary metrics of success are interdisciplinary collaborations and grant funding. We describe recent examples of how interdisciplinary collaboration, academic-community partnership, and pilot funding contributed to the development and funding of innovative interdisciplinary research, including the New York site of the HEALing Communities initiative. The processes are now being used to support interdisciplinary approaches for other translational public health issues.
Design and manufacture of hybrid metal composite structures using functional tooling made by additive manufacturing
Authors: Türk Daniel-Alexander , Rüegg Fabian , Biedermann Manuel , Meboldt Mirko 
Published: October 2019

This paper presents a novel manufacturing technique for complex-shaped, hybrid metal composite structures leveraging the design freedom of additive manufacturing (AM). The key novelty of this research is an approach for an autoclave-suitable and removable tooling, which consists of a 3D-printed functional shell and a structural filler material. In this process, a layup shell is produced with AM and filled with a temperature-resistant curing support to form a removable inner tooling. The functional shell has integrated design features for the positioning and the fixation of metallic interface elements and is removed after curing through integrated breaking lines. The feasibility of this manufacturing technique is demonstrated by fabricating a novel lightweight structure for the hydraulic quadruped (HyQ) robot. Selective laser sintering (SLS) was used to produce the functional shell tooling. Titanium interface elements made via selective laser melting (SLM) were assembled to the shell and co-cured to carbon fiber using an autoclave prepreg process. The resulting multi-material structure was tested in ultimate strength and successfully operated on the HyQ robot. Weight savings of 55% compared to a reference design and the mechanical viability of the multi-material structure indicate that the proposed manufacturing technique is appropriate for individualized hybrid composite structures with complex geometries.

Published: October 2019

AbstractThe Ross Ice Shelf (RIS) is host to a broadband, multimode seismic wavefield that is excited in response to atmospheric, oceanic and solid Earth source processes. A 34-station broadband seismographic network installed on the RIS from late 2014 through early 2017 produced continuous vibrational observations of Earth's largest ice shelf at both floating and grounded locations. We characterize temporal and spatial variations in broadband ambient wavefield power, with a focus on period bands associated with primary (10–20 s) and secondary (5–10 s) microseism signals, and an oceanic source process near the ice front (0.4–4.0 s). Horizontal component signals on floating stations overwhelmingly reflect oceanic excitations year-round due to near-complete isolation from solid Earth shear waves. The spectrum at all periods is shown to be strongly modulated by the concentration of sea ice near the ice shelf front. Contiguous and extensive sea ice damps ocean wave coupling sufficiently so that wintertime background levels can approach or surpass those of land-sited stations in Antarctica.
Semi-static variance-optimal hedging in stochastic volatility models with Fourier representation
Authors: Di Tella Paolo , Haubold Martin , Keller-Ressel Martin 
Published: October 2019

AbstractWe introduce variance-optimal semi-static hedging strategies for a given contingent claim. To obtain a tractable formula for the expected squared hedging error and the optimal hedging strategy we use a Fourier approach in a multidimensional factor model. We apply the theory to set up a variance-optimal semi-static hedging strategy for a variance swap in the Heston model, which is affine, in the 3/2 model, which is not, and in a market model including jumps.
No Safe Space: Neoliberalism and the Production of Violence in the Lives of Central American Migrants
Authors: Alvarez Linda 
Published: October 2019

AbstractThis paper explores the ways in which neoliberal policies enacted by elites across the Northern Triangle have led to increased violence in Central America, a lived experience that continues as individuals migrate to Mexico and the United States. In this work, I examine how neoliberal polices in the region have created limited economic opportunities and means of subsistence for the poor in Central America, as well as the rise of extra-legal actors and criminal enterprises. Together these conditions leave Central Americans with no choice but to migrate north. This paper then explores the violence migrants experience as they move through Mexico. In this stage of the journey, migrant bodies are objectified and then commodified as cheap labor for the global market as well as local economies of violence. Lastly, I discuss the multiple zones of violence that migrants experience at Mexico's border with the United States. This project relies on in-depth, semi-structured interviews (n= 99) with Central American migrants over the course of 4 years (2014–18). Ultimately, I find that for Central American migrants, violence can be a seemingly inescapable reality as neoliberal forces maintain and normalize violence in order to preserve an established social order at the expense of these migrants.
WESTERWALD STONEWARE AT KELMSCOTT MANOR: MORRIS, POTTERY AND THE POLITICS OF PRODUCTION
Authors: Chitty Gill , Stocker David 
Published: October 2019

Kelmscott Manor, the country home of William Morris, houses a remarkable collection of ceramics bearing a singular relationship to one of the most influential figures in Victorian cultural history. This study of Kelmscott’s collection of German stoneware reveals new interpretations of its production history and fascinating insights into its significance for the cultural context of Morris’s work. Based on a complete catalogue, the paper examines the ensemble of approximately thirty pieces of eighteenth- to nineteenth-century Westerwald stoneware, orgrès de Flandres, as it was known to Morris and his contemporaries. The Kelmscott group is the largest collection of this material known from an English historic house and has a composite and well-documented provenance. Supplementary material provided as an online appendix contains a fully illustrated, descriptive catalogue.Westerwald pottery of the seventeenth century and earlier has been extensively studied, but its ceramics of the late eighteenth to nineteenth centuries have received little attention. Most accounts stress the simplification of vessel forms and ‘degeneration’ of decorative designs during this period, leading towards mass-productionc1900. This paper re-assesses later Westerwald output, drawing attention to a vernacular pottery tradition of significant interest in its own right. This paper suggests that it was this continuing tradition of vernacular production and its naturalistic, decorative schemes that attracted the interest of Morris throughout his adult life, from the Red House experiment to the heyday of Morris & Co. Examining his writing on creativity, the minor arts and labour, the paper interpretsgrès de Flandresas an expression of Morris’s idealisation of the relationship between labour and craft production.
Breast cancer prevention in premenopausal women: role of the Mediterranean diet and its components

AbstractBreast cancer (BC) is a growing public health concern in most developed and developing countries. Since an increasing number of patients with BC are diagnosed before the menopause and premenopausal women show a more aggressive phenotype, there is consistent interest in promoting prevention strategies in order to reduce the incidence of BC in the premenopause. The Mediterranean diet (MD) has been reported to have beneficial effect in terms of cancer prevention. This healthy dietary pattern consists primarily of foods having important antioxidant properties along with a favourable fatty acid profile, all associated with a reduced risk of cancer. Due to the large variability in study subject characteristics, the protective role of the MD on BC still remains controversial and studies that have investigated the association between adherence to the MD and risk of BC in premenopausal women are fewer than those in postmenopausal women. In addition, the possibility that the beneficial effects of the MD are due to a single component or might more probably derive from the synergic effects of all components of the MD remains a scantly explored field. Considering the increased risk of recurrence and mortality rate of BC in premenopausal women as compared with postmenopausal women, the aim of the present report is to provide a general overview of the current evidence on the relationship between BC and the MD specifically in premenopausal women, and to emphasise the potential role of the MD as an effective measure to reduce the risk of developing BC in premenopausal women.
Simulating the impact of sodium reduction from packaged foods on population sodium intake in US adults and children
Authors: Dunford Elizabeth K , Poti Jennifer M 
Published: October 2019

AbstractObjective:To simulate the impact that Na reductions in food categories that are the largest contributors to dietary Na intake would have on population Na intake from packaged foods among US adults and children.Design:24 h Dietary recall data were used. For each store-bought packaged food product reported by participants, we generated sales-weighted Na content at the median and 25th percentile using Nutrition Facts Panel data from 193 195 products purchased by US households. The impact that Na reductions would have on population Na intake, overall and by sociodemographic subgroup, was examined.SettingsUS households.Participants:Children aged 2–18 years (n 2948) and adults aged >18 years (n 4878), 2011–2012 National Health and Nutrition Examination Survey.Results:Na intake from packaged foods was 1258 (se 21) mg for adults and 1215 (se 35) mg for children. Top-ten packaged food group sources contributed 67 % of Na intake. For adults and children, there was a decrease of 8·7 % (109 mg) and 8·0 % (97 mg), respectively, in Na intake if the top-ten sources reduced Na from the median to the 25th percentile. Although absolute reduction in intake varied between sociodemographic subgroups, significant differences were not observed.Conclusions:The study demonstrated that if Na reduction shifted the top-ten packaged food group sources of dietary Na intake from the median to 25th percentile, population Na intake would be reduced by 9 % in US adults and children. These findings will help inform the US government’s Na reduction targets, as well as policy makers’ understanding of differences in intake of critical sub-populations in the USA.

AbstractThe burrower bugScaptocoris castaneaPerty, 1830 (Hemiptera: Cydnidae) is an agricultural pest feeding on roots of several crops. The histology and ultrastructure of the salivary glands ofS. castaneawere described. The salivary system has a pair of principal salivary glands and a pair of accessory salivary glands. The principal salivary gland is bilobed with anterior and posterior lobes joined by a hilus where an excretory duct occurs. The accessory salivary gland is tubular with a narrow lumen that opens into the hilus near the excretory duct, suggesting that its secretion is stored in the lumen of the principal gland. The cytoplasm of the secretory cells is rich in the rough endoplasmic reticulum, secretory vesicles with different electron densities and mitochondria. At the base of the accessory gland epithelium, there were scattered cells that do not reach the gland lumen, with the cytoplasm rich in the rough endoplasmic reticulum, indicating a role in protein production. Data show that principal and accessory salivary glands ofS. castaneaproduce proteinaceous saliva. This is the first morphological description of theS. castaneasalivary system that is similar to other Hemiptera Pentatomomorpha, but with occurrence of basal cells in the accessory salivary gland.
A Review of Wave Spectrum Models as Applied to the Problem of Radar Probing of the Sea Surface

Published: October 2019

AbstractThe most common models of the wind wave spectrum are reviewed, and the compliance of the studied spectra with several fundamental criteria is estimated. These criteria are the ability to simulate diverse wave climate and agreement between model‐based calculations of the mean square slope and experimental data. The spreading function of the spectrum should also correspond to the experimentally measured Doppler spectrum, while the dependence of the radar backscatter cross section should conform to geophysical model functions for various wavelength ranges of incident electromagnetic radiation at moderate incidence angles (20–60°). An analysis has shown that none of the considered spectrum models fully satisfies all the criteria; thus, a new spectrum model for wind waves was developed. Boundary wave numbers for various wavelength ranges of incident electromagnetic radiation within the framework of a two‐scale surface model were determined for the new model. The spectrum model can be used to simulate ripple attenuation in oil slicks and to calculate the radar backscatter cross section inside slick.

AbstractRapid assessment of the volume and the rate at which gas and pyroclasts are injected into the atmosphere during volcanic explosions is key to effective eruption hazard mitigation. Here, we use data from a dense infrasound network deployed in 2017 on Mt. Etna, Italy, to estimate eruptive volume flow rates (VFRs) during small gas‐and‐ash explosions. We use a finite‐difference time‐domain approximation to compute the acoustic Green's functions and perform a full waveform inversion for a multipole source, combining monopole and horizontal dipole terms. The inversion produces realistic estimates of VFR, on the order of 4 × 104 m3/s and well‐defined patterns of source directivity. This is the first application of acoustic waveform inversion at Mt. Etna. Our results demonstrate that acoustic waveform inversion is a mature and robust tool for assessment of source parameters and holds potential as a tool to provide rapid estimates of VFR in near real time.
Dipole Structure of Mixed Layer Salinity in Response to El Niño‐La Niña Asymmetry in the Tropical Pacific

Published: October 2019

AbstractThe asymmetry of mixed layer salinity (MLS) anomalies in response to El Niño and La Niña events in the tropical Pacific is examined for the first time based on Argo observations and Estimating the Circulation and Climate of the Ocean simulation. The difference of MLS anomalies between El Niño and La Niña shows a dipole structure, with El Niño featuring strong negative salinity anomalies east of 160°E while La Niña shows remarkable positive salinity anomalies west of 160°E. A salinity budget analysis suggests that nonlinear zonal advection plays a dominant role in generating the asymmetric MLS structure. This dipole MLS structure acts to generate a dipole structure of barrier layer thickness and thus likely plays an important role in the development of El Niño–Southern Oscillation asymmetries in sea surface temperature.
Restoration of hand function with long-term paired associative stimulation after chronic incomplete tetraplegia: a case study

Abstract
Introduction
This case study explores the gains in hand function in an individual with a chronic spinal cord injury (SCI). The intervention was long-term paired associative simulation (PAS). We aimed to provide PAS until full recovery of hand muscle strength occurred, or until improvements ceased.

Case presentation
A 46-year-old man with traumatic C7 AIS B tetraplegia was administered PAS three times per week. After 24 weeks, PAS was combined with concomitant motor training of the remaining weak hand muscles. Outcome measures included the manual muscle test (MMT), motor-evoked potentials (MEPs), F-responses, hand functional tests, and the spinal cord independence measure (SCIM).

Discussion
After 47 weeks of PAS the subject had improved self-care and indoor mobility and was able to perform complex motor tasks (SCIM score improved from 40 to 56). His left hand regained maximum MMT score (total 75; increase of score from baseline condition 19); the effect remained stable in the 32-week follow up. In the right-hand muscles, MMT scores of 4–5 were observed in follow up (total 71; increase from baseline 48). Improved values were also observed in other outcomes. This is the first demonstration of long-term PAS restoring muscle strength corresponding to MMT scores of 4–5 in an individual with chronic SCI. The effect persisted for several months, indicating that PAS induces stable plastic changes in the corticospinal pathway.
