Published: August 2019

AbstractSpawning of polar cod (Boreogadus saida) in the vicinity of the Svalbard archipelago has not been directly observed. From the distribution pattern of polar cod 0-group observed during annual monitoring of the Barents Sea, it has, however, been inferred that spawning occurs in Svalbard waters most years. We wanted to investigate the possibility of back-tracking the larvae from these observed distribution areas to the spawning areas from which they originated and applied a coupled ocean–sea ice and particle tracking model to simulate the drift of particles released at suggested spawning sites. The model was run for 1 year (December 2006–September 2007), and the results were compared to observations of polar cod larvae in the autumns of 2007 and 2004–2010. The particles released in the western fjords were mostly retained in the fjords. For the rest of the suggested spawning grounds, the released particles drifted mostly clockwise around the archipelago. Model runs mainly indicated a drift pattern with end points that qualitatively match the main features of the August–September distribution of the polar cod 0-group observed. We conclude that the suggested spawning sites on the southern, northern and eastern sides of Svalbard could have caused a distribution of 0-group polar cod similar to that observed during August–September 2007. From the environmental factors experienced during drift of eggs and larvae and assumptions about habitat suitability for survival and growth, we conclude that spawning in the Svalbard area probably occurs on the southern and eastern sides and later than the area in the southeastern Barents Sea.

AbstractIntroductionDisease‐modifying treatments for Alzheimer's disease (AD) are likely to be offered only to patients with molecular evidence for Alzheimer pathology and expanded to patients with prodromal AD. We calculated the potential future costs of expanding the number of positron emission tomography (PET) and cerebrospinal fluid (CSF) tests in the United Kingdom.MethodsWe conducted a focused literature review and consulted experts to obtain information on the current use of PET and CSF to diagnose prodromal AD, staffing and equipment requirements for these tests, and associated costs.ResultsWe estimate annual costs of 100,000 extra amyloid PET scans and 100,000 extra CSF tests at £113 million and £48 million, respectively; these costs are likely to be higher in the first year.DiscussionThe budgetary impacts are not insignificant but are small in comparison to the likely market price of any disease‐modifying treatments or to the probable costs of missed or inaccurate diagnosis.

Published: August 2019

Under certain assumptions on CAT(0) spaces, we show that the geodesic flow is topologically mixing. In particular, the Bowen–Margulis’ measure finiteness assumption used by Ricks [Flat strips, Bowen–Margulis measures, and mixing of the geodesic flow for rank one CAT(0) spaces. Ergod. Th. & Dynam. Sys. 37 (2017), 939–970] is removed. We also construct examples of CAT(0) spaces that do not admit finite Bowen–Margulis measure.
The Great Second World War Vietnam and Java Famines
Authors: HUFF GREGG 
Published: August 2019

AbstractThis article provides quantitative assessments of the great famines that occurred in Vietnam and Java in 1944–1945, which together claimed the lives of some 3.4 million people. It shows that in both Vietnam and Java, harvest shortfalls, in which weather figured prominently, were so large that insufficient food was available to feed everyone. Nevertheless, in both instances, even with the pressures of war and weather, governments could have acted differently and largely, perhaps even wholly, prevented famine. Although Java's famine had few political repercussions, Vietnam's was instrumental in the August 1945 Viet Minh and communist revolution.

Published: August 2019

AbstractWe investigated changes in self-representation depending on language in Friulian–Italian bilinguals. The Temperament and Character Inventory (TCI) and the Junior-TCI were administered respectively to 24 adults and 25 children, both in Friulian and in Italian, at a distance of two weeks from each other. Variations in TCI were detected: both adults and children scored higher in Self-Directedness (a character trait) when using Italian than Friulian. Similar findings were observed for Novelty-Seeking (a temperament trait) in children and Cooperativeness (another character trait) in adults. Results are discussed considering previous studies on bilingualism and within the frame of the Friulian sociolinguistic context.

Abstract. Reduced serum 25(OH)D levels have been largely reported in vitiligo, which is an autoimmune skin disorder characterized by the appearance of achromic macules. Since vitamin D can positively modulate immune function and stimulate melanogenesis in vitro, a possible role of sufficient vitamin D levels in promoting the stability of the disease and repigmentation process might be hypothesized in vitiligo. Hence, we conducted an observational study on medical records related to 101 vitiligo patients, in order to correlate baseline 25(OH)D levels with the baseline vitiligo activity and repigmentation of vitiligo macules on a 6-month follow-up. According to our results, at baseline we found that active vitiligo was significantly associated with 25(OH)D deficiency (≤20 ng/mL) (P = 0.036) or insufficiency (21–29 ng/mL) (P = 0.041), while stable disease was significantly associated with sufficient 25(OH)D levels (30–100 ng/mL) (P = 0.043). After 6 months, vitiligo patients with sufficient 25(OH)D levels (30–100 ng/mL) achieved a significantly higher degree of repigmentation. In conclusion, our study provides a novel evidence of a significant positive association of sufficient 25(OH)D levels with the stability of the disease and a satisfactory repigmentation process in Caucasian adult vitiligo patients and strengthen the need to assess vitamin D status in vitiligo. The correlation between sufficient vitamin D levels and a satisfactory course of the disease opens the way for future randomized controlled trials assessing a possible beneficial role of vitamin D supplementation on vitiligo.

Abstract. The two hemispheres of the human brain are asymmetrically involved in representing a person’s motivational orientation: Approach motivation is reflected in greater activation of the left hemisphere, whereas avoidance motivation more strongly activates the right hemisphere. Visuospatial bias, as assessed in the line-bisection task, is often used as a simple behavioral measure of relative hemispheric activation. In three experiments, we investigated whether affect-induced approach and avoidance motivation are associated with spatial biases in line-bisection performance. Happy or terrifying pictures (Experiment 1, N = 70), happy or sad music (Experiment 2, N = 50), and joyful or frightening videos (Experiment 3, N = 90) were used to induce negative and positive affect. Mood-induction procedures successfully changed emotional states in the intended direction. However, our analyses revealed no effect of mood on visuospatial biases in the line-bisection task. Additional Bayesian analyses also provided more evidence against the hypothesized effect than in favor of it. Thus, visuospatial bias in line bisection does not seem to be a sensitive measure of approach and avoidance motivation induced by positive and negative affect.

AbstractLaboratory experiments report that detectable seismic velocity changes should occur in the vicinity of fault zones prior to earthquakes. However, operating permanent active seismic sources to monitor natural faults at seismogenic depth is found to be nearly impossible to achieve. We show that seismic noise generated by vehicle traffic, and especially heavy freight trains, can be turned into a powerful repetitive seismic source to continuously probe the Earth's crust at a few kilometers depth. Results of an exploratory seismic experiment in Southern California demonstrate that correlations of train‐generated seismic signals allow daily reconstruction of direct P body waves probing the San Jacinto Fault down to 4‐km depth. This new approach may facilitate monitoring most of the San Andreas Fault system using the railway and highway network of California.

AbstractStrain partitioning related to oblique plate convergence has long been debated in Northern Lesser Antilles. Geophysical data acquired during the ANTITHESIS cruises highlight that the sinistral strike‐slip Bunce Fault develops along the vertical, long, and linear discontinuity between the sedimentary wedge and a more rigid backstop. The narrowness of the 20‐ to 30‐km‐wide accretionary wedge and its continuity over ~850 km is remarkable. The Bunce Fault extends as far south as 18.5°N where it anastomoses within the accretionary prism where the sharp increase in convergence obliquity possibly acts as a mechanical threshold. Surface traces related to subducting seamounts suggest that 80% of the lateral component of the convergent motion is taken up by internal deformation within the accretionary prism and by the Bunce Fault. The absence of crustal‐scale, long‐term tectonic system south of the Anegada Passage casts doubt upon the degree of strain partitioning in the Northern Lesser Antilles.
Spatiotemporal Variability of Twenty‐First‐Century Changes in Site‐Specific Snowfall Frequency Over the Northwest United States
Authors: Catalano A. J. , Loikith P. C. , Aragon C. M. 
Published: August 2019

AbstractIn the Northwest United States, warming temperatures threaten mountain snowpacks. Reliable projections of snowfall changes are therefore critical to anticipate the timeline of change. However, producing such projections is challenging, as most state‐of‐the‐art climate models are limited in sufficiently resolving influential topography. Here we leverage atmospheric freezing level to estimate precipitation phase and project twenty‐first‐century snowfall frequency change at Snowpack Telemetry Network stations across the Northwest. Under “moderate” and “business‐as‐usual” emission pathways in Coupled Model Intercomparison Project phase 5 models, snowfall frequency is projected to decline at all stations. Business‐as‐usual declines accelerate after midcentury at most locations, whereas moderate declines decelerate. A “critical year” analysis identifies when decadal‐mean snowfall frequency is projected to fall below 50%, 25%, and 10% of cold‐season wet days. Results highlight regions particularly vulnerable to relatively near‐term change, such as the Cascade Range. Considerable station‐to‐station spatial variability emphasizes the value of this site‐specific approach.
Modeling the Magnetopause Shadowing Loss During the June 2015 Dropout Event
Authors: Tu Weichao , Xiang Zheng , Morley S. K. 
Published: August 2019

AbstractFast dropout of relativistic and ultrarelativistic electrons at both high and low L* regions were observed during the intense coronal mass ejection driven storm in June 2015. An improved radial diffusion model, using an event‐specific last closed drift shell and newly available radial diffusion coefficients (DLL), is implemented to simulate the magnetopause shadowing loss of electrons. The model captures the fast shadowing loss of electrons well at high L* regions after both interplanetary shocks, and reproduces the initial adiabatic loss of the high‐energy storage ring at low L* regions after the second strong shock. We show for the first time that using the event‐specific and K‐dependent last closed drift shell and improved DLL is critical to reproduce the observed dropout features, including the timing, location, and the butterfly electron pitch angle distribution. Future inclusion of the electromagnetic ion cyclotron wave scattering process is needed to model the observed further depletion of the storage ring.
Reconciling at‐a‐Station and at‐Many‐Stations Hydraulic Geometry Through River‐Wide Geomorphology
Authors: Brinkerhoff C. B. , Gleason C. J. , Ostendorf D. W. 
Published: August 2019

AbstractAt‐many‐stations hydraulic geometry (AMHG), while useful for estimating river discharge from satellite data, remains empirical and has yet to be reconciled with the at‐a‐station hydraulic geometry (AHG) from which it was originally derived. Here we present evidence, using United States Geological Survey field measurements of channel hydraulics for 155 rivers, that AMHG can be hydraulically and geomorphically reconciled with AHG. Our results indicate that AMHG is rightly understood as an expression of a river‐wide model of hydraulics driven by changes in slope imposed upon AHG physics. The explanatory power of AHG and this river‐wide model combine to determine whether AMHG exists: if both AHG and the river‐wide model adequately describe hydraulics, then we show that AMHG is a necessary mathematical consequence of these two phenomena. We also orient these findings in the context of river discharge estimation and other applications.
Reaction Route Selection for Cellulose Hydrogenolysis into C2/C3 Glycols by ZnO-Modified Ni-W/β-zeolite Catalysts

Published: August 2019

AbstractA β-zeolite-supported nickel and tungsten catalyst (Ni-W/β) was employed to generate C2/C3 glycols (ethylene and propylene glycols) in a satisfactory yield from cellulose. After optimizing the acidity of the support, the Ni-W synergy and the co-catalyst, the yield of C2/C3 glycols reached 70.1% (C %), with propylene glycol accounting for 51.1% of the product. This performance was attributed to the effective control of the major reaction steps, namely, hydrolysis, isomerization, retro-aldol condensation and hydrogenation, by the tailored Ni-W-ZnO/β catalyst. The characterization and reaction results indicated that the cellulose hydrolysis step was promoted by the appropriate acidic sites of the β-zeolite, and the reaction routes to C2/C3 glycols were influenced by the mass loading of Ni-W through the synergy of nickel and tungsten oxide, in which Ni is effective in the hydrogenation while W facilitates bond cleavage via a retro-aldol condensation (C6 to C2/C3). Moreover, with the leaching of metal during four cycles of reuse, the catalytic performance was also influenced by the synergy of Ni and W. In addition, the isomerization of glucose to fructose was promoted by ZnO and afforded a high yield of propylene glycol.
Towards perturbation prediction of biological networks using deep learning
Authors: Li Diya , Gao Jianxi 
Published: August 2019

AbstractThe mapping of the physical interactions between biochemical entities enables quantitative analysis of dynamic biological living systems. While developing a precise dynamical model on biological entity interaction is still challenging due to the limitation of kinetic parameter detection of the underlying biological system. This challenge promotes the needs of topology-based models to predict biochemical perturbation patterns. Pure topology-based model, however, is limited on the scale and heterogeneity of biological networks. Here we propose a learning based model that adopts graph convolutional networks to learn the implicit perturbation pattern factors and thus enhance the perturbation pattern prediction on the basic topology model. Our experimental studies on 87 biological models show an average of 73% accuracy on perturbation pattern prediction and outperforms the best topology-based model by 7%, indicating that the graph-driven neural network model is robust and beneficial for accurate prediction of the perturbation spread modeling and giving an inspiration of the implementation of the deep neural networks on biological network modeling.
Meloidogyne graminicola protein disulfide isomerase may be a nematode effector and is involved in protection against oxidative damage

Published: August 2019

AbstractThe rice root-knot nematode, Meloidogyne graminicola, is a serious pest in most rice-growing countries. Usually, nematodes employ antioxidants to counteract the harm of reactive oxygen species (ROS) and facilitate their infection. Here the gene encoding M. graminicola protein disulphide isomerase (MgPDI) was identified. The deduced protein is highly conserved in the putative active-site Cys-Gly-His-Cys. In situ hybridization showed that MgPDI was specifically localized within esophageal glands of pre-parasitic second stage juveniles (J2s). MgPDI was significantly up-regulated in the late parasitic J2s. Characterization of the recombinant protein showed that the purified MgPDI exhibited similar activities to other oxidases/isomerases such as the refolding of the scrambled RNase and insulin disulfide reductase and the protection of plasmid DNA and living cells from ROS damage. In addition, silencing of MgPDI by RNA interference in the pre-parasitic J2s lowered their multiplication factor. MgPDI expression was up-regulated in the presence of exogenous H2O2, whereas MgPDI silencing resulted in an increase in mortality under H2O2 stress. MgPDI is localized in the apoplast when transient expression in Nicotiana benthamiana leaves. The results indicated that MgPDI plays important roles in the reproduction and pathogenicity of M. graminicola and it also contributes to protecting nematodes from exogenous H2O2 stress.
Clinical Assessment of Characteristics of Apraxia of Speech in Primary Progressive Aphasia
Authors: Duncan E. Susan , Donovan Neila J. , Sajjadi Seyed Ahmad 
Published: August 2019

Purpose
We sought to examine interrater reliability in clinical assessment of apraxia of speech (AOS) in individuals with primary progressive aphasia and to identify speech characteristics predictive of AOS diagnosis.

Method
Fifty-two individuals with primary progressive aphasia were recorded performing a variety of speech tasks. These recordings were viewed by 2 experienced speech-language pathologists, who independently rated them on the presence and severity of AOS as well as 14 associated speech characteristics. We calculated interrater reliability (percent agreement and Cohen's kappa) for these ratings. For each rater, we used stepwise regression to identify speech characteristics significantly predictive of AOS diagnosis. We used the overlap between raters to create a more parsimonious model, which we evaluated with multiple linear regression.

Results
Results yielded high agreement on the presence (90%) and severity of AOS (weighted Cohen's κ = .834) but lower agreement for specific speech characteristics (weighted Cohen's κ ranging from .036 to .582). Stepwise regression identified 2 speech characteristics predictive of AOS diagnosis for both raters (articulatory groping and increased errors with increased length/complexity). These alone accounted for ≥ 50% of the variance of AOS severity in the constrained model.

Conclusions
Our study adds to a growing body of research that highlights the difficulty in objective clinical characterization of AOS and perceptual characterization of speech features. It further supports the need for consensus diagnostic criteria with standardized testing tools and for the identification and validation of objective markers of AOS. Additionally, these findings underscore the need for a training protocol if diagnostic tools are to be effective when shared beyond the research teams that develop and test them and disseminated to practicing speech-language pathologists, in order to ensure consistent application.
Implementation and Perceptions of Classroom-Based Service Delivery: A Survey of Public School Clinicians
Authors: Green Laura , Chance Paula , Stockholm Melissa 
Published: August 2019

Purpose

The choice of service delivery model is important for public school clinicians. Despite a theoretical emphasis on inclusive classroom-based services, data from a recent American Speech-Language-Hearing Association Schools Survey indicated that the pullout model is still the more frequently used approach (
American Speech-Language-Hearing Association, 2016
). In the current study, public school clinicians' use and perceptions of inclusion were examined to better understand potential influences on its implementation.

Method
Three hundred forty-four school-based clinicians completed an online survey about their training in and implementation of inclusion services, along with their perceptions of positive and potentially challenging aspects of this model. Descriptive data were examined, and the relationships of use and perceptions to issues such as caseload size, training, school setting, teacher factors, and administrative support were analyzed. Additionally, qualitative analysis was used to examine responses to 3 open-ended questions.

Results
Over half of the respondents served 1%–25% of their caseload through an inclusion model, and it was most frequently utilized to address language and social skills. Teacher collaboration and planning time were the 2 most frequently reported keys to inclusion success and were also 2 of the most frequently reported challenges to implementation.

Conclusions
The majority of the respondents reported many positive aspects of inclusion, yet they also reported many of the same challenging perceptions and roadblocks that existed when speech-language pathologists were surveyed over 20 years ago. Based on the results of this study, training in the inclusion model, teacher “buy-in,” planning time, and administrative support are relevant to successful use of classroom-based intervention.
Superpixel segmentation and machine learning classification algorithm for cloud detection in remote‐sensing images
Authors: Shi Yueting , Wang Weijiang , Gong Qishu , Li Dingyi 
Published: August 2019

Cloud detection is a fundamental yet challenging topic in remote‐sensing image processing. The authors propose a method for multi‐dimensional feature extraction and superpixel segmentation, and use a voting‐based clustering ensemble to capture the whole target shape. In order to further identify clouds, snow‐covered lands, and bright buildings on remote‐sensing images, they first implement an Ostu threshold to get high grey‐level sub‐regions, and then extract the descriptors of these sub‐regions and put them into the softmax regression classifier. Regarding these methods, the authors conduct experiments using GF‐1 remote‐sensing images. The results demonstrate the effectiveness and excellency of their proposed method.
