Authors: Ma Wei , Lei Shen , Sun Yujun , Grabosky Jason 
Published: July 2019

AbstractIn order to understand the management of regional vegetation, numerical classification and ordination are widely used to investigate community distribution and vegetation features. In particular, two-way indicator-species analysis programs (TWINSPAN) classifies plots and species into different groups. De-trended correspondence analysis (DCA) and canonical correspondence analysis (CCA) reflects the relationship between community and site conditions. Afforestation withLarix olgensisHerry. Plantations is a suitable restoration strategy on post-agricultural fields in the Lesser Khingan Mountains. The results of this study show how these plantations develop over time to establish a reliable pathway model by measuring and clarifying the succession process. Twenty-eightL. olgensisplantations along a 48-year chronosequence of afforestation were investigated with a quadrat sampling method. Species composition, community structure attributes of diversity, and site conditions were analyzed. Communities were classified by TWINSPAN into five successional stages: immature, juvenile, mid-aged, near-mature and mature. Classifications were validated by DCA and CCA analysis. Site conditions such as soil and litter thickness, soil organic matter, soil density, and pH were measured. Successional stages varied in community composition and species population, accompanied by time from afforestation and a gradient of site conditions. This gradient showed changes in vegetation occurrence and diversity coinciding with changes in soil conditions. The study showed thatL. olgensisplantations had marked predominance in growth and were associated with improved soil fertility and the formation of a stable plant community.
The Czar and the Slaves: Two Puzzles in the History of International Arbitration
Authors: Ostdiek Bennett , Witt John Fabian 
Published: July 2019

AbstractIn 1822, the Russian czar resolved a dispute over compensation for slaves fleeing to British lines during the War of 1812. American observers have long asserted that this canonical decision favored the United States. But new debate has recently arisen among historians. Uncovering evidence from diplomatic archives, this Article concludes that the czar did indeed side with the United States. Moreover, the case demonstrates how nineteenth-century American statesmen pressed international law into service in support of slavery.

Published: July 2019

ABSTRACT:Objective:Focal cortical dysplasia (FCD) is a common cause of refractory, focal onset epilepsy in children. Interictal, scalp electroencephalograph (EEG) markers have been associated with these pathologies and epilepsy surgery may be an option for some patients. We aim to study how scalp EEG and magnetic resonance imaging (MRI) markers of FCD affect referral of these patients for surgical evaluation.Methods:A single-center, retrospective review of children with focal onset epilepsy. Patients were included if they were between 1 month and 18 years of age, had focal onset seizures, prolonged scalp EEG monitoring, and an MRI conducted after 2 years of age. Statistics were carried out using the chi-squared and student’st-test, as well as a logistic regression model.Results:Sixty-eight patients were included in the study. Thirty-seven of these patients were referred to a comprehensive pediatric epilepsy program (CPEP) for surgical evaluation, and of these 22% showed FCD EEG markers, 32% FCD MRI markers, and 10% had both. These markers were also present in patients not referred to a CPEP. The MRI markers were significantly associated with CPEP referral, whereas EEG markers were not. Neither marker type was associated with epilepsy surgery.Conclusion:This study found that children with focal onset epilepsy were more likely to be referred for surgical evaluation if they were medically refractory, or were diagnosed with FCD or tumor on MRI. Scalp EEG markers of FCD were not associated with CPEP referral. The online tool CASES may be a useful physician guide for identifying appropriate children for epilepsy surgery referral.

Authors: Darmawikarta Denise , Sourour Michel , Couban Rachel , Kamath Sriganesh , Reddy Kesava KV , Shanthanna Harsha 
Published: July 2019

ABSTRACT:Background:Post-craniotomy pain can be severe and is often undermanaged. Opioids can interfere with neurological monitoring and are associated with adverse effects. This systematic review aimed to identify measures of opioid-free analgesia and compare their effectiveness with opioid analgesia for post-craniotomy pain in patients with supratentorial tumors.Methods:EMBASE, MEDLINE, and Cochrane databases were searched from their inception to February 14, 2017, for randomized controlled trials (RCTs) evaluating opioid versus non-opioid analgesia post-supratentorial craniotomy. Two reviewers independently carried out study selection and data extraction. Risk of bias assessment was performed using the Cochrane Collaboration’s tool. Outcomes were pain control (changes to pain scores or use of rescue analgesia) and adverse effects. Considering the number of studies and heterogeneity, a narrative synthesis was done without pooling and results were summarized using tables. Non-opioids were assessed for the potential to be equivalent to opioid-based analgesics for pain relief and adverse effects.Results:Of 467 RCTs, 4 met our inclusion criteria (n= 186 patients). Patients with scalp blocks (2 RCTs) had less post-operative nausea and vomiting (PONV), but scalp block was not superior to morphine for analgesia. Acetaminophen (1 RCT) was less likely to induce PONV but provided inadequate pain relief compared to morphine and sufentanil. Dexmedetomidine (1 RCT) was not superior to remifentanil for analgesia although it delayed time to rescue analgesia.Conclusions:Limited evidence suggests that scalp blocks and dexmedetomidine have the potential to eliminate the need for opioid analgesia. Multimodal analgesia should be considered as significant opioid-sparing effects have been shown.
Incidence, Awareness, and Reporting of Sport-Related Concussions in Manitoba High Schools
Authors: Bergeron Glen L. 
Published: July 2019

ABSTRACT:Background and Objectives: Federal and provincial governments in Canada are promoting provincial legislation to prevent and manage sport-related concussions (SRCs). The objective of this research was to determine the incidence of concussions in high school sport, the knowledge of the signs, symptoms, and consequences of SRC, and how likely student athletes are to report a concussion. Methods: A cross-sectional survey of athletes (N = 225) from multiple sports in five high schools in one Manitoba school division was conducted. Results: Participants in this study were well aware of the signs, symptoms, and consequences of SRC. Cognitive and emotional symptoms were the least recognized consequences. SRC is prevalent in high schools in both males and females across all sports. Of the 225 respondents, 35.3% reported having sustained an SRC. Less than half (45.5%) reported their concussion. Athletes purposely chose not to report a concussion in games (38.4%) and practices (33.8%). Two major barriers to reporting were feeling embarrassed (3.4/7) and finding it difficult (3.5/7) to report. There was, however, strong agreement (Mean 5.91/7, SD 0.09) when asked if they intend to report a concussion should they experience one in the future. Conclusions: The results suggest that high school athletes would benefit from more SRC education. Coaches and team medical staff must be trained to be vigilant for the mechanism, signs, and symptoms of injury in both game and practice situations. This study will also inform the implementation of pending legislation in Manitoba and perhaps other provinces in Canada.
Systematic review of genetic variants associated with cognitive impairment and depressive symptoms in Parkinson’s disease
Authors: D’Souza Tyrra , Rajkumar Anto P. 
Published: July 2019

AbstractObjective:Cognitive impairment and depression are among the most prevalent and most disabling non-motor symptoms in Parkinson’s disease (PD). The genetic factors that are associated with these symptoms remain uncertain. This systematic review aims to summarise the prevailing evidence from all genetic association studies investigating the genetic variants associated with cognitive impairment and depressive symptoms in people with PD.Method:A systematic review using five online databases: PubMed, PsycINFO, CINAHL, EMBASE and OpenGrey (PROSPERO protocol: CRD42017067431). We completed the quality assessment using the Q-Genie tool.Results:2353 articles were screened, and 43 articles were found to be eligible to be included. A meta-analysis of studies investigatingLRRK2rs34637584 confirmed that the minor allele carriers had significantly less cognitive impairment (p= 0.015). Further meta-analyses showed thatGBAvariants rs76763715 (p< 0.001) and rs421016 (p= 0.001) were significantly associated with more cognitive impairment in people with PD. Minor alleles ofGBAvariants rs76763715, rs421016, rs387906315 and rs80356773 were associated with more depressive symptoms in PD. Moreover,APOEε4 allele has been associated with more cognitive impairment in PD.BDNF(rs6265) andCRY1(rs2287161) variants have been associated with more depressive symptoms in people with PD.Conclusions:PD carriers ofGBAvariants are at high risk for cognitive decline and depression. Screening for these variants may facilitate early identification and effective management of these non-motor symptoms. The molecular mechanisms underlying favourable cognitive functioning inLRRK2rs34637584 variant carriers warrant further investigation.
BIFURCATION PROPERTIES FOR A CLASS OF CHOQUARD EQUATION IN WHOLE ℝ3

AbstractThis paper concerns the study of some bifurcation properties for the following class of Choquard-type equations:(P)$$\left\{ {\begin{array}{*{20}{l}} { - \Delta u = \lambda f(x)\left[ {u + \left( {{I_\alpha }*f( \cdot )H(u)} \right)h(u)} \right],{\rm{ in }} \ {{\mathbb{R}}^3},}\\ {{{\lim }_{|x| \to \infty }}u(x) = 0,\quad u(x) > 0,\quad x \in {{\mathbb{R}}^3},\quad u \in {D^{1,2}}({{\mathbb{R}}^3}),} \end{array}} \right.$$where${I_\alpha }(x) = 1/|x{|^\alpha },\,\alpha \in (0,3),\,\lambda > 0,\,f:{{\mathbb{R}}^3} \to {\mathbb{R}}$is a positive continuous function andh:${\mathbb{R}} \to {\mathbb{R}}$is a bounded Hölder continuous function. The main tools used are Leray–Schauder degree theory and a global bifurcation result due to Rabinowitz.
THE LEGAL CHARACTER OF ARTICLE 18 OF THE VIENNA CONVENTION ON THE LAW OF TREATIES
Authors: Gragl Paul , Fitzmaurice Malgosia 
Published: July 2019

AbstractThe main reason for Article 18 being one of the most opaque provisions of the Vienna Convention is that it establishes a relatively vague ‘interim obligation’ for States to refrain from acts which would defeat the object and purpose of a treaty between its signature and ratification. Although the existence of such an interim obligation has been recognized by States and in various international legal regimes, it remains problematic since Article 18 neither defines nor determines its own contours and when and under which conditions it is being breached. It goes without saying that the legal consequences of a possible breach of this provision are left equally unclear. It remains uncertain how the interim obligation of Article 18 fits into the general international law of treaties; what its legal nature and temporal scope is; which role the principle of good faith plays as a possibly underlying principle of this provision; and how we should understand the object and purpose of a treaty and how it can be defeated. Furthermore, its apparent focus seems to be on bilateral rather than multilateral treaties, but this exclusive application of this interim obligation to bilateral treaties would contravene both the expressed and implied intent of the drafters. Therefore, this article also discusses how Article 18 fits within the normative system of international law and law-making treaties, such as human rights treaties.
STATE RESPONSIBILITY FOR MODERN SLAVERY: UNCOVERING AND BRIDGING THE GAP
Authors: Webb Philippa , Garciandia Rosana 
Published: July 2019

AbstractInternational law prohibits slavery and slavery-like practices under treaties that have been in force for more than a century. Yet, contemporary forms of slavery are one of the prevailing challenges for the international community, with 40.3 million people in modern slavery on any given day in 2016. The State has been largely overlooked as a perpetrator or accomplice in the global movement to eradicate modern slavery. The hand of the State can however be found in contemporary cases of modern slavery. This article identifies five scenarios of State involvement in modern slavery and aims to uncover and bridge the responsibility gap.
Sensor-based Navigation of Omnidirectional Wheeled Robots Dealing with both Collisions and Occlusions
Authors: Khelloufi Abdellah , Achour Nouara , Passama Robin , Cherubini Andrea 
Published: July 2019

SUMMARYNavigation tasks are often subject to several constraints that can be related to the sensors (visibility) or come from the environment (obstacles). In this paper, we propose a framework for autonomous omnidirectional wheeled robots that takes into account both collision and occlusion risk, during sensor-based navigation. The task consists in driving the robot towards a visual target in the presence of static and moving obstacles. The target is acquired by fixed – limited field of view – on-board cameras, while the surrounding obstacles are detected by lidar scanners. To perform the task, the robot has not only to keep the target in view while avoiding the obstacles, but also to predict its location in the case of occlusion. The effectiveness of our approach is validated through several experiments.
Effects of habitat, leaf damage and leaf rolling on the predation risk of caterpillars in the tropical rain forest of Borneo

Published: July 2019

AbstractAddressing what affects predation among caterpillars, we conducted an experiment in a Bornean rain forest on 212 clay models of Tortricidae caterpillars (the herbivore) and 53 trees of Kopsia pauciflora (the host), located either in the open or under closed canopies. We predicted that the frequency of predatory attacks towards caterpillars increases (1) in canopy gaps and (2) on leaves damaged by herbivory, but (3) decreases among caterpillars that wrap their body in leaves. Each plant with caterpillar models was consecutively allocated to one of four treatments: caterpillars artificially rolled in leaves vs caterpillars on unrolled leaves, and caterpillars on artificially damaged vs undamaged leaves. Each time, caterpillar models were placed on the plants for 48 h, and then replaced with new models that were subjected to a new treatment. On average, our caterpillar models had a 21% chance of being attacked per 24 h. More attacks were performed by insects (81.6%) than birds. The attack frequency did not depend on the canopy cover or on leaf damage, but decreased among models rolled in leaves. This pattern was mainly attributable to insect attacks, which were also more frequent than bird attacks. Overall, the Tortricidae caterpillars seem to suffer comparable predation rates in the open and under closed canopies irrespective of the herbivory damage of leaves, but their leaf-rolling behaviour might reduce predation.
ASYMPTOTIC BEHAVIORS FOR CORRELATED BERNOULLI MODEL

Published: July 2019

AbstractWe consider a class of correlated Bernoulli variables, which have the following form: for some 0 < p < 1,
$$\begin{align}{P(X_{j+1}=1 \vert {\cal F}_{j})= (1-\theta_j)p+\theta_jS_j/j,}\end{align}$$where 0 ≤ θj ≤ 1, $S_n=\sum _{j=1}^nX_j$ and ${\cal F}_n=\sigma \{X_1,\ldots , X_n\}$. The aim of this paper is to establish the strong law of large numbers which extend some known results, and prove the moderate deviation principle for the correlated Bernoulli model.
Who Wants to Make America Great Again? Understanding Evangelical Support for Donald Trump
Authors: Margolis Michele F. 
Published: July 2019

AbstractWhite evangelicals overwhelmingly supported Donald Trump in the 2016 election, producing extensive debate as to who evangelicals are, what it means to be an evangelical in the United States today, and whether the electoral results are surprising or not. This paper offers empirical clarity to this protracted discussion by asking and answering a series of questions related to Trump's victory in general and his support from white evangelicals in particular. In doing so, the analyses show that the term “evangelical” has not become a synonym for conservative politics and that white evangelical support for Trump would behigherif public opinion scholars used a belief-centered definition of evangelicalism rather than relying on the more common classification strategies based on self-identification or religious denomination. These findings go against claims thatnominalevangelicals, those who call themselves evangelicals but are not religious, make up the core of Trump's support base. Moreover, strong electoral support among devout evangelicals is not unique to the 2016 election but rather is part of a broader trend of evangelical electoral behavior, even when faced with non-traditional Republican candidates. Finally, the paper explores why white evangelicals might support a candidate like Trump. The paper presents evidence that negative partisanship helps explain why devout evangelicals—despite Trump's background and behaviors being cause for concern—coalesced around his presidential bid. Together, the findings from this paper help make sense of both the 2016 presidential election and evangelical public opinion, both separately and together.
Scouringrush (Equisetum spp.) control in dryland winter wheat
Authors: Kerbs Blake D. , Hulting Andrew G. , Lyon Drew J. 
Published: July 2019

AbstractThe adoption of chemical fallow rotations in Pacific Northwest dryland winter wheat production has caused a weed species composition shift in which scouringrush has established in production fields. Thus, there has been interest in identifying herbicides that effectively control scouringrush in winter wheat–chemical fallow cropping systems. Field experiments were established in growers’ fields near Reardan, WA, in 2014, and The Dalles, OR, in 2015. Ten herbicide treatments were applied to mowed and nonmowed plots during chemical fallow rotations. Scouringrush stem densities were quantified the following spring and after wheat harvest at both locations. Chlorsulfuron plus MCPA-ester resulted in nearly 100% control of scouringrush through wheat harvest. Before herbicide application, mowing had no effect on herbicide efficacy. We conclude chlorsulfuron plus MCPA-ester is a commercially acceptable treatment for smooth and intermediate scouringrush control in winter wheat–chemical fallow cropping systems; however, the lack of a positive yield response when scouringrushes were controlled should factor into management decisions.
Humidity Effects on Effective Elastic Properties of Rock: An Integrated Experimental and Numerical Study
Authors: Hossain M. Manzur , Arns Ji‐Youn , Liang Zhirong , Chen Zhixi , Arns Christoph H. 
Published: July 2019

AbstractThe surface energy of minerals increases due to a loss of humidity. In rocks this leads to strains without applying external stress (stress‐free strain) and affects the rocks' elastic response. We utilize finite element calculations on X‐ray micro‐CT images to analyze the extreme cases of surface energy contributions and no surface energy contributions for the small strain case. Including surface energy utilizing published surface energies of quartz significantly increases the simulated bulk modulus. Grain contacts are considered perfectly cemented and therefore do not contribute to this difference. Confining pressure is not applied in the experiment to estimate the impact of surface energy to avoid the effect of grain contact slippage due to different stress paths. In addition, we compare simulated moduli with experimentally determined parameters. In this case, we incorporate confining pressure in the experiment since grain contacts are not considered in the simulation. The main reason to use confining pressure in the experiment here is to close the grain contacts with a view that the resulting porosity reduction is negligible.

AbstractHeterogeneous ice nucleating particle (INP) concentrations are reported for a site on the eastern margin of Beijing, China, during the period 4 May to 4 June 2018. INP concentrations were measured continuously at −20, −25, and −30 °C in a repeating cycle by a newly developed, automated continuous flow diffusion chamber, and reached concentrations as high as 2800 sL−1 during dust‐impacted periods. Study average concentrations were 70 ± 70, 230 ± 290, and 430 ± 500 sL−1 at −20, −25, and −30 °C. There was no clear relationship between pollution periods, identified based on fine‐mode particle concentration increases, and INP concentrations or characteristics. Other anthropogenic emissions, such as non‐combustion industrial or agricultural activities play an unresolved role.

AbstractThe greater wax moth, Galleria mellonella Linnaeus (Lepidoptera: Galleriinae), is a ubiquitous pest of the honeybee, and poses a serious threat to the global honeybee industry. G. mellonella pheromone system is unusual compared to other lepidopterans and provides a unique olfactory model for pheromone perception. To better understand the olfactory mechanisms in G. mellonella, we conducted a transcriptomic analysis on the antennae of both male and female adults of G. mellonella using high-throughput sequencing and annotated gene families potentially involved in chemoreception. We annotated 46 unigenes coding for odorant receptors, 25 for ionotropic receptors, two for sensory neuron membrane proteins, 22 for odorant binding proteins and 20 for chemosensory proteins. Expressed primarily in antennae were all the 46 odorant receptor unigenes, nine of the 14 ionotropic receptor unigenes, and two of the 22 unigenes coding for odorant binding proteins, suggesting their putative roles in olfaction. The expression of some of the identified unigenes were sex-specific, suggesting that they may have important functions in the reproductive behavior of the insect. Identification of the candidate unigenes and initial analyses on their expression profiles should facilitate functional studies in the future on chemoreception mechanisms in this species and related lepidopteran moths.
