Published: October 2019

Abstract
Image hashing is an efficient technique of many multimedia systems, such as image retrieval, image authentication and image copy detection. Classification between robustness and discrimination is one of the most important performances of image hashing. In this paper, we propose a robust image hashing with singular values of quaternion singular value decomposition (QSVD). The key contribution is the innovative use of QSVD, which can extract stable and discriminative image features from CIE L*a*b* color space. In addition, image features of a block are viewed as a point in the Cartesian coordinates and compressed by calculating the Euclidean distance between its point and a reference point. As the Euclidean distance requires smaller storage than the original block features, this technique helps to make a discriminative and compact hash. Experiments with three open image databases are conducted to validate efficiency of our image hashing. The results demonstrate that our image hashing can resist many digital operations and reaches a good discrimination. Receiver operating characteristic curve comparisons illustrate that our image hashing outperforms some state-of-the-art algorithms in classification performance.

ABSTRACTXanthomonas is a well-studied genus of bacterial plant pathogens whose members cause a variety of diseases in economically important crops worldwide. Genomic and functional studies of these phytopathogens have provided significant understanding of microbial-host interactions, bacterial virulence and host adaptation mechanisms including microbial ecology and epidemiology. In addition, several strains of Xanthomonas are important as producers of the extracellular polysaccharide, xanthan, used in the food and pharmaceutical industries. This polymer has also been implicated in several phases of the bacterial disease cycle. In this review, we summarise the current knowledge on the infection strategies and regulatory networks controlling virulence and adaptation mechanisms from Xanthomonas species and discuss the novel opportunities that this body of work has provided for disease control and plant health.

Published: October 2019

Abstract
Hepatitis D virus (HDV) infection is associated with severe liver-related morbidity and mortality. The prevalence of HDV is rising especially among people who abuse drugs and immigrants from endemic areas. Reliable diagnostic assays with enhanced sensitivity and specificity are essential for screening at-risk populations. Until recently, interferon has been the only treatment for hepatitis D. Its efficacy is, however, limited and it is associated with significant side effects. A number of novel antiviral agents that target various stages of the HDV life cycle show promising results. They are currently in different phases of clinical development. This review focuses on the changing epidemiology, novel therapeutic agents, and updated management of chronic hepatitis delta.
Effectiveness of Combined Cognitive and Physical Interventions to Enhance Functioning in Older Adults With Mild Cognitive Impairment: A Systematic Review of Randomized Controlled Trials

Published: October 2019

Abstract

Background and Objectives
Cognitive training delivered in conjunction with physical activity, may help to optimize aging and delay or prevent dementia in individuals with mild cognitive impairment (MCI). However, their efficacy is less well studied compared to pharmaceutical treatments. This systematic review synthesizes the emerging evidence on combined cognitive-physical interventions for enhancing functioning in older adults with MCI, with implications for practice and research.

Research Design and Methods
We searched the PubMed, PsycINFO, Ageline, Medline, Web of Science and ProQuest databases, and hand-searched articles published between July 2013 and November 2018. Only randomized controlled trials which incorporated cognitive and physical components targeted to individuals with MCI over the age of 50 were eligible. Our search yielded 10 eligible, independent articles.

Results
Intervention participants with MCI self-reported, or demonstrated, improved functioning across a range of cognitive (global cognitive function, executive function, processing speed, memory, attention, mood, emotion, motivation, brain cortex, orientation), and physical (gait, balance, mobility) outcomes. Interventions which combined cognitive-physical training were comparable to those which isolated these same elements, in terms of their effects on executive function, processing speed, attention, mood, and cardiorespiratory fitness.

Discussion and Implications
There is preliminary evidence to support the positive effects of multicomponent interventions to improve cognitive-motor abilities in older adults at risk of developing dementia. The strength of this research evidence is, however, limited. Longitudinal studies are needed to determine whether these effects are maintained over time. The optimal intervention intensity and length also need to be established.

Published: October 2019

Abstract
The aim of this paper is to study, by using the mathematical tools developed by Chałupnik, Touzé, and Van der Kallen, the effect of the Frobenius twist on $\operatorname{Ext}$-group in the category of strict polynomial functors. As an application, we obtain explicit formulas of cohomology of the orthogonal groups and symplectic ones.
Very Early Blood Diffusion of the Active Lethal and Edema Factors of Bacillus anthracis After Intranasal Infection
Authors: Rougeaux Clémence , Becher François , Goossens Pierre L , Tournier Jean-Nicolas 
Published: October 2019

Abstract

Background
Lethal and edema toxins are critical virulence factors of Bacillus anthracis. Few data are available on their presence in the early stage of intranasal infection.

Methods
To investigate the diffusion of edema factor (EF) and lethal factor (LF), we use sensitive quantitative methods to measure their enzymatic activities in mice intranasally challenged with a wild-type B anthracis strain or with an isogenic mutant deficient for the protective antigen.

Results
One hour after mouse challenge, although only 7% of mice presented bacteremia, LF and EF were detected in the blood of 100% and 42% of mice, respectively. Protective antigen facilitated the diffusion of LF and EF into the blood compartment. Toxins played a significant role in the systemic dissemination of B anthracis in the blood, spleen, and liver. A mouse model of intoxination further confirmed that LT and ET could diffuse rapidly in the circulation, independently of bacteria.

Conclusions
In this inhalational model, toxins have disseminated rapidly in the blood, playing a significant and novel role in the early systemic diffusion of bacteria, demonstrating that they may represent a very early target for the diagnosis and the treatment of anthrax.

Published: October 2019

AbstractBackgroundLevels of antibodies induced by the measles virus–containing vaccine have been shown to decline over time, but there is no formal recommendation about testing immunized subjects (in particular, healthcare workers [HCWs]) to investigate the persistence of measles immunoglobulin G (IgG).MethodsThis study aims to evaluate the long-term immunogenicity of measles vaccine in a sample of medical students and residents of the University of Bari who attended the Hygiene Department for a biological risk assessment (April 2014–June 2018).ResultsTwo thousand immunized (2 doses of measles-mumps-rubella [MMR] vaccine) students and residents were tested; 305 of these (15%) did not show protective anti-measles IgG. This proportion was higher among subjects who received vaccination at ≤15 months (20%) than in those who received vaccination at 16–23 months (17%) and at ≥24 months (10%) (P &lt; .0001). After an MMR vaccine booster dose, we noted a seroconversion of 74% of seronegative HCWs. The overall seroconversion rate after a second dose (booster) was 93%. No serious adverse events were noted after the booster doses.ConclusionsAn important proportion of subjects immunized for measles do not show a protective IgG titer in the 10 years after vaccination. Our management strategy seems consistent with the purpose of evidencing immunological memory.
Spin versions of the complex trigonometric Ruijsenaars–Schneider model from cyclic quivers
Authors: Fairon Maxime 
Published: October 2019

AbstractWe study multiplicative quiver varieties associated to specific extensions of cyclic quivers with $m\geq 2$ vertices. Their global Poisson structure is characterized by quasi-Hamiltonian algebras related to these quivers, which were studied by Van den Bergh for an arbitrary quiver. We show that the spaces are generically isomorphic to the case $m=1$ corresponding to an extended Jordan quiver. This provides a set of local coordinates, which we use to interpret integrable systems as spin variants of the trigonometric Ruijsenaars–Schneider (RS) system. This generalizes to new spin cases recent works on classical integrable systems in the RS family.

AbstractObjectiveElectronic consultations (e-consults) are clinician-to-clinician communications that may obviate face-to-face specialist visits. E-consult programs have spread within the US and internationally despite limited data on outcomes. We conducted a systematic review of the recent peer-reviewed literature on the effect of e-consults on access, cost, quality, and patient and clinician experience and identified the gaps in existing research on these outcomes.Materials and MethodsWe searched 4 databases for empirical studies published between 1/1/2015 and 2/28/2019 that reported on one or more outcomes of interest. Two investigators reviewed titles and abstracts. One investigator abstracted information from each relevant article, and another confirmed the abstraction. We applied the GRADE criteria for the strength of evidence for each outcome.ResultsWe found only modest empirical evidence for effectiveness of e-consults on important outcomes. Most studies are observational and within a single health care system, and comprehensive assessments are lacking. For those outcomes that have been reported, findings are generally positive, with mixed results for clinician experience. These findings reassure but also raise concern for publication bias.ConclusionDespite stakeholder enthusiasm and encouraging results in the literature to date, more rigorous study designs applied across all outcomes are needed. Policy makers need to know what benefits may be expected in what contexts, so they can define appropriate measures of success and determine how to achieve them.
Identification and Characterization of Two Sensory Neuron Membrane Proteins From Onion Maggot (Diptera: Anthomyiidae)
Authors: Yang Huiyuan , Ning Shuoying , Sun Xiao , Chen Chuan , Liu Lingxiao , Feng Jinian 
Published: October 2019

Abstract
Sensory neuron membrane proteins (SNMPs) in insects are critical peripheral olfactory proteins and act as markers for pheromone detection. However, the SNMPs for onion maggot, Delia antiqua Meigen, a world-wide subterranean pest, have not been previously characterized. In this study, we first report the cloning and characterization of two novel SNMPs from D. antiqua, DantSNMP1 and DantSNMP2. Sequence alignment and phylogenetic analysis showed that DantSNMP1 and DantSNMP2 are very similar to the previously reported SNMP1 and SNMP2 isolated from other dipteran insects but they share low identity with each other. Further expression profile experiments showed that DantSNMP1 is antenna-specific, while DantSNMP2 is expressed both in antennae and nonantennal tissues. Immunocytochemical localization experiments showed that DantSNMP1 was expressed only in sensilla trichodae, which suggests that this protein is involved in pheromone reception in insect olfaction.
Insecticidal and Behavioral Effect of Microparticles of Pimpinella anisum Essential Oil on Larvae of Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)

Published: October 2019

Abstract
The Colorado potato beetle ranks as one of the most important potato pests, mainly due to its high feeding rate during all developmental stages, particularly third and fourth larval instar, and high fecundity. The effect of essential oil (EO) from anise (Pimpinella anisum L. [Apiales: Apiaceae]) prepared as conventional and encapsulated (EN) formulations on the mortality and antifeedant responses of young larvae of Colorado potato beetles was studied to evaluate the insecticidal and antifeedant effects of five concentrations of this EO and to assess the persistence of both formulations on potato plants.
The EN formulation had a significantly higher residual amount compared with that of the conventionally formulated EO. Significantly different values of LC50 and LC90 (ppm) were established for the EO (LC50 = 1,700 and LC90 = 9500) and EN (LC50 = 3,100 and LC90 = 14,300) formulations. The effects of both P. anisum formulations (EO and EN) applied topically to Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) larvae were distinctly different from those observed with the contact treatment. At the highest concentration of 20,000 ppm, the mortality of the second instars of the L. decemlineata larvae did not exceed 25%. On the other hand, both tested formulations of P. anisum were highly effective when administered orally. The encapsulated EO formulation achieved a distinctly higher biological activity.
Our results confirm that the EO from P. anisum, especially the encapsulated formulation, has high insecticidal properties that may lead to the development of new organic products for the control of Colorado potato beetles.
Transepistemic abduction: reasoning across epistemic domains
Authors: Gibson Andrew , Bruza Peter 
Published: October 2019

Abstract
Frequently people draw on different domains of knowledge to reach a conclusion that seems reasonable despite being difficult to justify from the perspective of a single domain. For example, there appears to be no reason for ethics to involve mathematics, nor is there a mechanism in mathematics to embrace moral questions; however, both ethics and mathematics are likely to be involved in resolving questions about how an autonomous vehicle should make decisions in a social context. In this paper, we present a specialized mode of reasoning, transepistemic abduction (TeA), which establishes how two agents, in order to satisfactorily explain a phenomenon, reason across two epistemic domains despite each agent being ignorant of the other’s domain knowledge.
We formalize TeA with epistemic logic and provide a naturalized example that brings together a psychosocial agent and a computational agent for the analysis of subjective text. We find that interaction between agents is critical to the process of TeA and that there are limits to the formalization while remaining true to naturalized reasoning. We conclude with some important implications of these findings for future work in this area.
Superior mesenteric venous thrombosis as a first manifestation of Antithrombin III deficiency in the postoperative course of laparoscopic sleeve gastrectomy: a case study of 2 patients from 1211 bariatric patients

Published: October 2019

Abstract
Superior mesenteric venous thrombosis (SMVT) following laparoscopic sleeve gastrectomy (LSG) is a rare, potentially life-threatening complication, which presents either isolated, or as a part of portal/mesenteric/splenic vein thrombosis. Distinction between them possibly confers an important clinical and prognostic value. Antithrombin III (ATIII) deficiency causes an hypercoagulable state which predisposes to SMVT. We report the clinical presentation and treatment of two patients among 1211 LSGs (incidence = 0.165%) that presented with isolated SMVT and ATIII deficiency in an Academic Bariatric Center. Both patients had an unremarkable past medical history; none was smoker or had a previously known thrombophillic condition/thrombotic episode. Mean time of presentation was 15.5 days after LSG. Despite aggressive resuscitative and anticoagulation measures, surgical intervention was deemed necessary. No mortalities were encountered. Coagulation tests revealed ATIII deficiency in both patients.
The Morphology of the Basic Verbal Stems in Eastern Jibbali/Śħrḗt
Authors: Al Kathiri Amir Azad Adli , Dufour Julien 
Published: October 2019

Abstract
This paper is a presentation of the verbal morphology of the basic stems (Ga and Gb morphological classes) in a dialect of Jibbali/Śħrḗt (Modern South Arabian sub-family, Semitic family) spoken in Eastern Dhofar (Sultanate of Oman). It aims, as far as possible, at an exhaustive description of the existing verbal types and its core is a collection of paradigms obtained through elicitation. Focus is given to the system of phonologically-triggered allomorphy that characterizes the Jibbali/Śħrḗt (and Modern South Arabian) verbal morphology, whereby to a given inflectional cell correspond several morphological patterns the choice between which is determined by the characteristics of the root. Surface phonological processes necessary to an apprehension of verbal forms are also summarized.
Formation of N-rich field stars in the high-density building blocks of the Galactic bulge
Authors: Bekki Kenji 
Published: October 2019

ABSTRACT
Recent observational studies of the Galactic bulge by APOGEE have revealed that about 1 per cent of the bulge stars have rather high nitrogen abundances ([N/Fe] > 0.5). We here numerically investigate in what physical conditions these N-rich stars (NRSs) can be formed in spherical and discy stellar systems with stellar masses of $10^7\!-\!10^9 \, {\rm M}_{\odot }$ that are the bulge’s building blocks. The principal results are as follows. A large fraction (>0.5) of new stars formed from interstellar medium polluted (ISM) by ejecta of asymptotic giant branch stars can have [N/Fe] > 0.5 within stellar systems, if the gas mass fraction of ISM (fg) is low (≤0.03). The mass fraction of NRS among all stars (fnrs) can be higher than ≈1 per cent within ≈0.5 Gyr time-scale of star formation, if the mean stellar densities (ρs) of the systems are higher than $\approx 0.1 \, {\rm M}_{\odot }$ pc−3. The [N/Fe] distributions depend on ρs, fg, and age distributions of their host stellar systems. NRSs have compact and discy spatial distributions within their host systems and have rotational kinematics. Based on these results, we propose that the vast majority of the bulge’s NRSs originate not from globular clusters (GCs) but from its high-density building blocks. We suggest that NRSs in the Galactic stellar halo have the same origin as those in the bulge. We also suggest that low-density dwarf spheroidal and gas-rich dwarfs are unlikely to form NRSs. GCs are not only the formation sites of NRS.
Light element variations within the different age-metallicity populations in the nucleus of the Sagittarius dwarf

Published: October 2019

ABSTRACT
The cluster M54 lies at the centre of the Sagittarius dwarf spheroidal galaxy, and therefore may be the closest example of a nuclear star cluster. Either in situ star formation, inspiralling globular clusters, or a combination have been invoked to explain the wide variety of stellar sub-populations in nuclear star clusters. Globular clusters are known to exhibit light element variations, which can be identified using the photometric construct called a chromosome map. In this letter, we create chromosome maps for three distinct age-metallicity sub-populations in the vicinity of M54. We find that the old, metal-poor population shows the signature of light element variations, while the young and intermediate-age metal rich populations do not. We conclude that the nucleus of Sagittarius formed through a combination of in situ star formation and globular cluster accretion. This letter demonstrates that properly constructed chromosome maps of iron-complex globular clusters can provide insight into the formation locations of the different stellar populations.

Abstract

BACKGROUND
Despite our inability to accurately predict survival in many cancer patients, a life expectancy of at least 3 mo is historically necessary to be considered for surgical treatment of spinal metastases.

OBJECTIVE
To compare health-related quality of life (HRQOL) in patients surviving <3 mo after surgical treatment to patients surviving >3 mo to assess the validity of this inclusion criteria.

METHODS
Patients who underwent surgery for spinal metastases between August 2013 and May 2017 were retrospectively identified from an international cohort study. HRQOL was evaluated using generic and disease-specific outcome tools at baseline and at 6 and 12 wk postsurgery. The primary outcome was the HRQOL at 6 wk post-treatment measured by the Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ).

RESULTS
A total of 253 patients were included: 40 patients died within the first 3 mo after surgery and 213 patients survived more than 3 mo. Patients surviving <3 mo after surgery presented with lower baseline performance status. Adjusted analyses for baseline performance status did not reveal a significant difference in HRQOL between both groups at 6 wk post-treatment. No significant difference in patient satisfaction at 6 wk with regard to their treatment could be detected between both groups.

CONCLUSION
When controlled for baseline performance status, quality of life 6 wk after surgery for spinal metastasis is independent of survival. To optimize improvement in HRQOL for this patient population, baseline performance status should take priority over expected survival in the surgical decision-making process.
