Copper-chelating peptide from salmon by-product proteolysate
Authors: Vo Tam D.L. , Pham Khoa Trong
Published: May 2020

The aims of this study included evaluation of copper-binding capacity (CBC) and amino acid composition of salmon by-product proteolysate and its peptide fractions, optimization of hydrolysis condition, and identification of copper-binding peptides from the proteolysate. The result was that under the ideal hydrolysis (Neutrase, temperature of 45 °C, pH 7, enzyme:substrate (E:S) proportion of 72.24 U/g protein and hydrolysis time of 8.02 h), the proteolysate had the indispensable amino acid content at approximately 38.7% and also displayed the maximal CBC of 15163.6 µg Cu2+/g protein. Besides, four peptide fractions of 10–30 kDa, 3–10 kDa, 1–3 kDa, and <1 kDa were recovered using ultrafiltration, among which the <1 kDa fraction had the highest CBC of 10852.00 ± 895.06 µgCu2+/g protein. A copper-binding peptide, Phe-Ile-Asp-Asp-Asp-Ala-Phe-Ile-Arg (1110 Da), was identified from this fraction using tandem mass spectrometry (MS/MS). As a whole, the proteolysate/peptides could be used for copper enhancement that could shield human body from copper inadequacy disorders.

Published: May 2020

Hot air drying is a commonly used technology in the preservation of red radish. This study was designed to investigate the correlations among total polyphenol content, total flavonoid content, antioxidant activities and polyphenol compounds in hot air dried red radish via chemometric analysis. UHPLC-QqQ-MS/MS analysis detected nine non-anthocyanin polyphenols and one anthocyanin in fresh and dried red radish samples, and found that hot air drying at 80 °C caused an increase in the p-coumaric acid and ferulic acid content of the red radish. The integral effect of hot air drying on the polyphenol profile of red radish was analyzed by principle component analysis, while sparse partial least squares-discriminant analysis showed that hot air drying induced changes mainly in the contents of poncirin, naringenin, phloetin and cyanidin-3-glucoside. These polyphenol degradations occurred as non-spontaneous and endothermic reactions during the hot air drying process, following first-order reaction kinetics.

Adherence to Dietary Recommendations and Food Retail Market Structure: Is There a Connection?
Authors: Volpe Richard , Cai Xiaowei , Schroeter Christiane , Mancino Lisa
Published: May 2020

We pair IRI household purchase records with Nielsen TDLinx data on the retail food environment to investigate the associations between retail market structure and Americans’ adherence to the Dietary Guidelines. We focus specifically on fruit and vegetable consumption, as proxied by purchases. Controlling for various household characteristics, we find that increased market concentration is associated with lower produce consumption and weaker adherence to recommendations. We also find a number of small but significant associations with respect to the presence of nontraditional retail formats.
Short-term analysis of internal and external CORS clocks
Authors: Maciuk Kamil
Published: May 2020

The International GNSS Service (IGS) provides high-accuracy clock products for both GNSS satellites and stations. On board of each GNSS satellite are located 3–4 atomic oscillators. In the case of CORS oscillators, the majority of them are equipped with internal oscillators and a part uses external, high-rate clocks. In the IGS network there are four types of external oscillators: quartz, rubidium, caesium and H-maser. These CORS are often reference stations for precise GNSS measurements or for time transfer. In this paper the author provides analyses of the internal and external stability of the reference stations oscillators via the usage of Allan variations. The results show a strong advantage of the external clocks over internal ones by about five orders of magnitude.

Published: May 2020

Background

Experiencing early-life stress plays an important role in the pathophysiology of anxiety disorders. Ferulic acid is a phenolic compound found in some plants which has several pharmacological properties. N-methyl-D-aspartate (NMDA) receptors are involved in the pathophysiology of mood disorders. In this study we aimed to assess the anxiolytic-like effect of ferulic acid in a mouse model of maternal separation (MS) stress by focusing on the possible involvement of NMDA receptors.

Methods

Mice were treated with ferulic acid (5 and 40 mg/kg) alone and in combination with NMDA receptor agonist/antagonist. Valid behavioral tests were performed, including open field test (OFT) and elevated plus maze test (EPM), while quantitative real time polymerase chain reaction (qRT-PCR) was used to evaluate gene expression of NMDA subunits (GluN2A and GluN2B) in the hippocampus.

Results

Findings showed that treatment of MS mice with ferulic acid increased the time spent in the central zone of the OFT and increased both open arm time and the percent of open arm entries in the EPM. Ferulic acid reduced the expression of NMDA receptor subunit genes. We showed that administration of NMDA receptor agonist (NMDA) and antagonist (ketamine) exerted anxiogenic and anxiolytic-like effects, correspondingly. Results showed that co-administration of a sub-effective dose of ferulic acid plus ketamine potentiated the anxiolytic-like effect of ferulic acid. Furthermore, co-administration of an effective dose of ferulic acid plus NMDA receptor agonist (NMDA) attenuated the anxiolytic-like effect of ferulic acid.

Conclusions

In deduction, our findings showed that NMDA, partially at least, is involved in the anxiolytic-like effect of ferulic acid in the OFT and EPM tests.
Mitigation of aflatoxin B1- and sodium arsenite-induced cytotoxicities in HUC-PC urinary bladder cells by curcumin and Khaya senegalensis
Authors: Olugbami Jeremiah Olorunjuwon , Damoiseaux Robert , Odunola Oyeronke Adunni , Gimzewski James Kazimierz
Published: May 2020

Background

Concomitant exposure to environmental/occupational toxicants such as aflatoxin B1 (AFB1) and arsenic in some regions of the world has been well reported. Therefore, this calls for the assessment of the efficacy of agents such as phytochemicals, which are already known for their ethno-medicinal uses in prophylaxis/remediation. We investigated the possible cytotoxic bio-interactions between AFB1 and sodium arsenite (SA) in urinary bladder cells. We also assessed the cytoprotective effects of curcumin and the ethanol stem bark extract of Khaya senegalensis (K2S).

Methods

The cells were exposed to graded levels of AFB1, SA, curcumin, and K2S for 24, 48, and 72 h. Subsequently, using optimum toxic concentrations of AFB1 and SA, respectively, the influence of non-toxic levels of curcumin and/or K2S was tested on exposure of the cells to AFB1 and/or SA. Hoechst 33342/propidium iodide staining technique was used to determine the end-points due to cytotoxicity with changes in adenosine triphosphate (ATP) levels determined using Promega’s CellTiter-Glo luminescent assay.

Results

Co-treatment of the cells with AFB1 and SA resulted in synergy in cytotoxic effects. Cytotoxicity was reduced by 3.5- and 2.9-fold by pre-treatment of the cells with curcumin and K2S before treatment with AFB1, while post-treatment resulted in 1.1- and 2.6-fold reduction, respectively. Pre-exposure of the cells with curcumin and K2S before treatment with SA ameliorated cytotoxicity by 3.8- and 3.0-fold, but post-treatment caused a 1.2- and 1.3-fold reduction, respectively.

Conclusions

Pre-treatment of the cells with either curcumin or K2S exhibited cytoprotective effects by ameliorating AFB1- and SA-induced cytotoxicity with inferred tendencies to prevent carcinogenesis.
Antidepressant-like effect of Albizia zygia root extract in murine models
Authors: Kumbol Victor Wumbor-Apin , Abotsi Wonder Kofi Mensah , Biney Robert Peter
Published: May 2020

Background

Albizia zygia (DC.) J.F. Macbr. (Leguminosae) has been used to treat mental disorders in traditional African medicine. Nonetheless, there is limited scientific evidence to justify its present use. The aim of this study was to evaluate the antidepressant activity of the hydroethanolic extract of A. zygia roots (AZE) in murine models.

Methods

AZE was evaluated in the tail suspension test, forced swim test, and the repeated open-space swim test of depression. In order to elucidate the mechanisms of action, the activity of AZE was re-evaluated after treating mice with selective inhibitors of monoamine biosynthesis. The potential of AZE to influence spontaneous locomotion was also examined.

Results

AZE (100–1000 mg/kg, p.o.) reduced the immobility time of mice in the tail suspension and forced swim tests (at least p < 0.05). In the repeated open-space swim test, AZE reduced the immobility time (at least p < 0.05) while concomitantly increasing the distance swam by mice (p < 0.01). However, the antidepressant-like activity of AZE was attenuated by α-methyl-para-tyrosine and reserpine (p < 0.0001) but not para-chlorophenylalanine.

Conclusions

The results of this study indicate that AZE possesses antidepressant-like properties and support the traditional use of AZE for the treatment of depression.

Authors: Oyeyemi Ajibade O. , Oseni Olatunde A. , Babatunde Adebimpe O. , Molehin Olorunfemi R.
Published: May 2020

Background

Cadmium serves as a major pollutant in the environment and it has been documented for its widespread harmful effects. This study sought to investigate the prophylactic and the curative effects of aqueous and methanolic leaf extracts of Polyalthia longifolia against cadmium-induced hepatotoxicity in rats.

Methods

Animals in group I served as the normal control and administered distilled water only for 14 days, group II was administered cadmium (4 mg/kg/body weight) for 7 days, groups III and IV rats served as the prophylactic group and were pre-treated with P. longifolia aqueous and methanolic leaf extract for 7 days and then exposed to cadmium for another 7 days, serving as pre-treatment group, groups V, VI, VII, and VIII served as curative groups and were first exposed to cadmium for 7 days and then post-treated with 100 and 200 mg/kg body weight of aqueous extract and 100 and 200 mg/kg body weight of methanolic extract P. longifolia for another 7 days.

Results

Pre- and post-treatment with both extracts of P. longifolia revealed a significant hepatoprotective ability by decreasing the alanine transaminase, alkaline phosphatase, aspartate transaminase, acid phosphatase, gamma glutamyl transferase enzymatic activities were elevated due to cadmium intoxication. Pre- and post-treatment with aqueous and methanolic extract of P. longifolia extract significantly decreased hepatic malondialdehyde levels, together with an improvement in the antioxidant status of superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase, and reduced glutathione of rats exposed to cadmium. Histopathology examinations also confirm the above biochemical findings.

Conclusion

The findings from this work suggested that P. longifolia may be beneficial in ameliorating the cadmium-induced hepatotoxicity and oxidative stress in rats.
Effectiveness of yogic visual concentration (Trataka) on cognitive performance and anxiety among adolescents
Authors: Sherlee J. Ida , David Anita
Published: May 2020

Background

Cognition is the mental process of acquiring knowledge, understanding senses and synchronizing all the electrical activity that is constantly received and generated through the eye. Purpose of the present study was to assess the effectiveness of yogic visual concentration (Trataka) on cognitive performance and anxiety among adolescents studying in selected schools at Chennai.

Methodology

This study was designed to assess cognitive performance and anxiety among students using quantitative approach. True Experimental study design was used for this study. Pretest assessment of cognitive performance and anxiety was done by standardized tools (Stroop color word test, Hamilton anxiety scale) for Experimental and Control groups. Intervention of yogic visual concentration (Trataka) was experimented in one group. Control group were kept on routine activities. Post test assessment of cognitive performance and anxiety by standardized tools was performed on experimental and control groups. The data were analyzed by descriptive statistics and inferential statistics. The 0.05 level of significance was used.

Results

A significant difference in the mean difference of color word score, color score, word score and inference score between the study and control groups at the level of p<0.0001 was observed. Results indicate an association in the cognitive performance (word) with background variables such as, gender, father’s occupation in the study group during the post test and no association in the control group. There were no associations between anxiety cognitive performance (color and word) and demographic variables in both groups.

Conclusion

The study concluded that there is a greater effect on Yogic visual concentration (Trataka) on cognitive performance and anxiety among adolescent students, therefore the study proved the hypothesis.
Immediate effect of Kapalbhathi pranayama on short term heart rate variability (HRV) in healthy volunteers
Authors: Lalitha S. , Maheshkumar K. , Shobana R. , Deepika C.
Published: May 2020

Objectives

Kapalbhathi Pranayam (Kapal = forehead; bhati = shining) is a breathing exercise that has been practiced to cleanse the frontal brain in traditional practices like yoga. Still, there exists a dearth of literature on the effect of Kapalbhathi pranayama on physiological systems. So this present study was carried out to find the immediate effect of “kapalbhathi Pranayam” practice for the period of 5 min on cardiac autonomic function among the healthy volunteers.

Materials and methods

Apparently 50 healthy volunteers includes both sex were participated. They were randomly divided into Pranayama (n−25) and control (n−25) group. Pranayama group was practiced kapalbhathi pranayama 5 min (5 cycles) and control group was allowed to do normal breathing (12–16 breath/min). Lead II ECG was recorded for 5 min using simple AD converter before, immediately after practice and 20 min of recovery period.

Results

One way Analysis of variance (ANOVA) followed by post hoc test was done using R statistical software. There was a significant (p < 0.05) parasympathetic withdrawal (Root Mean Square of the Successive Differences (RMSSD) – p < 0.04 and HF n.u – p < 0.05) was found in the pranayama group immediately after practice and its was changed to parasympathetic domination (RMSSD – p < 0.04 and HF n.u – p < 0.05) after 20 min of recovery period.

Conclusion

The present study suggested that though there was parasympathetic withdrawal immediately after practicing kapalbhathi pranayama, 20 min after the recovery period showed a parasympathetic domination in the pranayama group subjects. However, further studies are required to warrant the findings of this study.

A convergent numerical method to recover the initial condition of nonlinear parabolic equations from lateral Cauchy data
Authors: Le Thuy Thi Thu , Nguyen Loc Hoang
Published: May 2020

We propose a new numerical method for the solution of the problem of the reconstruction of the initial condition of a quasilinear parabolic equation from the measurements of both Dirichlet and Neumann data on the boundary of a bounded domain. Although this problem is highly nonlinear, we do not require an initial guess of the true solution. The key in our method is the derivation of a boundary value problem for a system of coupled quasilinear elliptic equations whose solution is the vector function of the spatially dependent Fourier coefficients of the solution to the governing parabolic equation. We solve this problem by an iterative method. The global convergence of the system is rigorously established using a Carleman estimate. Numerical examples are presented.

Published: May 2020

The rapid progression of the coronavirus disease 2019 (COVID-19) outbreak presented extraordinary challenges to the US health care system, particularly straining resources in hard hit areas such as the New York metropolitan region. As a result, major changes in the delivery of obstetrical care were urgently needed, while maintaining patient safety on our maternity units. As the largest health system in the region, with 10 hospitals providing obstetrical services, and delivering over 30,000 babies annually, we needed to respond to this crisis in an organized, deliberate fashion. Our hospital footprint for Obstetrics was dramatically reduced to make room for the rapidly increasing numbers of COVID-19 patients, and established guidelines were quickly modified to reduce potential staff and patient exposures. New communication strategies were developed to facilitate maternity care across our hospitals, with significantly limited resources in personnel, equipment, and space. The lessons learned from these unexpected challenges offered an opportunity to reassess the delivery of obstetrical care without compromising quality and safety. These lessons may well prove valuable after the peak of the crisis has passed.

Published: May 2020

This paper details a route classification method for American football using a template matching scheme that is quick and does not require manual labeling. Pre-defined routes from a standard receiver route tree are aligned closely with game routes in order to determine the closest match. Based on a test game with manually labeled routes, the method achieves moderate success with an overall accuracy of 72% of the 232 routes labeled correctly.
Understanding draws in Elo rating algorithm
Authors: Szczecinski Leszek , Djebbi Aymen
Published: May 2020

This work is concerned with the interpretation of the results produced by the well known Elo algorithm applied in various sport ratings. The interpretation consists in defining the probabilities of the game outcomes conditioned on the ratings of the players and should be based on the probabilistic rating-outcome model. Such a model is known in the binary games (win/loss), allowing us to interpret the rating results in terms of the win/loss probability. On the other hand, the model for the ternary outcomes (win/loss/draw) has not been yet shown even if the Elo algorithm has been used in ternary games from the very moment it was devised. Using the draw model proposed by Davidson in 1970, we derive a new Elo-Davidson algorithm, and show that the Elo algorithm is its particular instance. The parameters of the Elo-Davidson are then related to the frequency of draws which indicates that the Elo algorithm silently assumes games with 50% of draws. To remove this assumption, often unrealistic, the Elo-Davidson algorithm should be used as it improves the fit to the data. The behaviour of the algorithms is illustrated using the results from English Premier League.
Introduction: Shades of partitivity: Formal and areal properties
Authors: Ihsane Tabea , Stark Elisabeth
Published: May 2020

At the heart of this special issue are partitive elements (i. e., partitive articles, partitive pronouns, and partitive case markers) which can express different “shades” of partitivity, namely true partitivity, pseudopartitivity, or indefiniteness, that is, the absence of a part-whole relation in the meaning, in contrast to (pseudo)partitivity. Since these partitive elements express (at least) two such notions, as they can be truly partitive but often are not, the questions around partitivity are complex, interrelated and challenging. This special issue, with a strong and wide crosslinguistic (typological) coverage, deals with two overarching topics: first, the geographical distribution of partitive elements and the identification of potential instances of language contact, and, second, sometimes in combination with the first topic, the formal description and explanation of different partitive constructions.
Indefinite determiners in informal Italian: A preliminary analysis
Authors: Cardinaletti Anna , Giusti Giuliana
Published: May 2020

This paper presents the results of a pilot study on the distribution of indefinite determiners in contexts with narrow scope interpretation in current informal Italian. It individuates the available forms and presents their diatopic distribution. The research is based on data collected through an online questionnaire designed to detect optionality. The results show that in narrow scope indefinite contexts, i. e., negative statements, both the zero determiner and the definite article are widespread throughout the country. The partitive determiner is only found in episodic sentences and is limited to restricted geographic areas. In all contexts and areas, a large degree of optionality is found. In some context and area, however, it is possible to identify one form more prominent than the others. This can be related to the context, which may favour some specialized meaning of one specific form, e. g., saliency and small quantity, or to diatopic variation due to language contact with the dialect, as shown by comparing present-day informal Italian with the dialectal data reported in AIS and analysed in (Cardinaletti and Giusti. 2018. Indefinite determiners: Variation and optionality in Italo-Romance. In Diego Pescarini & Roberta D’Alessandro (eds.), Advances in Italian dialectology: Sketches of Italo-Romance grammars, 135–161.

Contact-induced change in the languages of Europe: The rise and development of partitive cases and determiners in Finnic and Basque
Authors: Luraghi Silvia , De Smit Merlijn , Igartua Iván
Published: May 2020

This paper explores the hypothesis of contact-induced change for the rise of the partitive case in Finnic languages and of the partitive case/determiner in Basque. On the basis of the well-established Indo-European partitive-genitive case and taking into account the lack of such a basis on the Uralic side, we argue that the partitive case in Finnic languages has arisen as a result of Balto-Slavic influence. Concerning the Basque partitive determiner, we likewise suggest a contact scenario (with Romance languages) as being responsible for the development of an entire system of determiners, including the definite and possibly the indefinite article as well as the partitive marker, which originates in an old ablative ending but crucially lacks the morphological properties characteristic of Basque inflectional markers.
Layers of (un)boundedness: The aspectual–quantificational interplay of quantifiers and partitive case in Finnish object arguments
Authors: Huumo Tuomas
Published: May 2020

I present an account of the interplay between quantifiers and the partitive–accusative case alternation in Finnish object marking, with special reference to the aspectual and quantificational semantics of the clause. The case alternation expresses two oppositions (in affirmative clauses): (a) bounded (accusative) vs. unbounded (partitive) quantity, (b) culminating (accusative) vs. non-culminating (partitive) aspect. The quantifiers analyzed are of two main types: (i) mass quantifiers (e. g.,paljon‘a lot of’,vähän‘(a) little’), which quantify a mass expressed by a mass noun or a plural form, (ii) number quantifiers (e. g.,moni‘many’,usea‘a number of’), which quantify a multiplicity of discrete entities expressed by a count noun in the singular or plural. Finnish mass quantifiers only quantify nominals in the partitive, while number quantifiers agree with the quantified nominal in number and case and are used throughout the case paradigm. With a mass quantifier, the partitive form of the quantified nominal expresses unbounded quantity, which the quantifier then renders bounded (quantized). This is why object phrases with mass quantifiers behave like accusative objects: they express a bounded quantity together with culminating aspect. Number quantifiers quantify both accusative and partitive objects, in the singular and plural. Such objects are able to express aspect and quantity at two levels: (i) that of the individual component events which concern one entity each; (ii) that of the higher-order event which concerns the whole quantity expressed. I argue that the case marking of the object relates primarily to level (i), while the meaning of the number quantifier relates to level (ii). This is why a number quantifier typically renders the quantity bounded and the aspect culminating at level (ii), even when the partitive case expresses unboundedness or lack of culmination at level (i).
Bretona-marking of (internal) verbal arguments: A result of language contact?
Authors: Stark Elisabeth , Widmer Paul
Published: May 2020

We discuss a potential case of borrowing in this paper: Bretona- ‘of’, ‘from’ marking of (internal) verbal arguments, unique in Insular Celtic languages, and reminiscent of Gallo-Romancede/du- (anden-) arguments. Looking at potential Gallo-Romance parallels of three Middle Breton constructions analyzed in some detail (awith indefinite mass nominals in direct object position,a-marking of internal arguments under the scope of negation,a[allomorphsan(ez)-/ahan-] with personal pronouns for internal arguments, subjects (mainly of predicative constructions) and as expletive subjects of existential constructions), we demonstrate that even if there are some semantic parallels and one strong structural overlap (aanddeunder the scope of negation), the amount of divergences in morphology, syntax and semantics and the only partially fitting relative chronology of the different constructions do not allow to conclude with certainty that language-contact is an explanation of the Breton facts, which might have come into being also because of internal change (bound to restructuring of the pronominal system in Breton). More research is necessary to complete our knowledge ofa-marking in Middle Breton and Modern Breton varieties and on the precise history of Frenchen, in order to decide for one or the other explanation.
Convergence and divergence in the expression of partitivity in French, Dutch, and German
Authors: Sleeman Petra , Ihsane Tabea
Published: May 2020

This paper focusses on the so-called partitive pronoun in French and Dutch, and the corresponding data in German, a language which is assumed not to have partitive pronouns in its standard, in contrast to certain dialectal varieties. Taking the diverse uses of the French partitive pronoun en as a starting point, we investigate the corresponding constructions in Dutch and German. The ultimate aim of the paper is to develop an analysis accounting for the similarities and differences between these languages in relation to the presence/absence of the partitive pronoun. To reach our objectives, we rely on data collected in a Grammaticality Judgment Test taken by native speakers of French, Dutch and German. We put together theory and experimental data in a crosslinguistic perspective investigating three languages that differ in their uses of partitive elements and formalize the results in a model in which the partitive pronoun can replace different portions of the nominal structure.
Partitivity in Slavic-Romance language contact: The case of Molise Slavic in Italy
Authors: Breu Walter
Published: May 2020

Molise Slavic is a south Slavic micro-language, spoken in three municipalities in the Italian region of Molise. It has been in a situation of total language contact with Romance varieties for about 500 years, with strong foreign influence on all linguistic levels. This paper is intended as a contribution to two combined fields of linguistics: contact linguistics and the expression of partitivity in Slavic in different settings. The paper opens with a short description of the position of the (morphological)partitivecase in Russian, followed by a comparison of the role of case in expressing partitive objects in Russian, Croatian and Molise Slavic. The subsequent section will deal with other means of rendering pure and ablativic partitivity in Italian as the dominant model language and in the Molise Slavic replica, in particular with respect to the similarities and differences in existential constructions. Special attention will be paid to the Italian partitive particleneand its formal and functional equivalents in Molise Slavic, including the particlena/ne, partitive personal pronouns, quantifiers, the genitive and the role of intonation and word order. Finally we will test various hypotheses about the origin of the particlena/ne, whose formal variation in one of the Molise Slavic dialects causes serious problems for both loanword integration and semantic calquing.
Marginal Argument Structure constructions: the [VtheNtaboo-wordout of]-construction in Post-colonial Englishes
Authors: Hoffmann Thomas
Published: May 2020

Argument Structure constructions – abstract, schematic constructions that are considered to encode basic human event construals – have received considerable attention in the constructionist literature. At the same time, languages sometimes also possess what can be considered Marginal Argument constructions that are partly lexically filled and considerably more specialized in meaning, such as the VtheNtaboo-wordout of-construction. The present study focusses on the latter construction drawing on the Corpus of Web-based Global English (GloWbE). In particular, it provides empirical evidence that the productivity of the verb slot can be shown to correlate positively with the phase of a variety in the Dynamic Model.
DholeCuon alpinusin Satchari National Park: on the first verifiable evidence from northeast Bangladesh
Authors: Zakir Tania , Debbarma Harish , Akash Muntasir
Published: May 2020

The distribution range of the globally Endangered dholeCuon alpinusoverlaps mixed evergreen mid-hill forests of northeastern Bangladesh but lacks any authentic documentation. With the first evidence from this region, we observed the activity pattern of dhole, of its prey and of human activities in Satchari National Park, a part of a larger northeastern forested area, Raghunandan Hill Reserve Forest – the northernmost fringe of the Baramura Hills of India. We obtained 32 photos of solitary individuals on eight different events from six out of 587 camera trap days. Naïve occupancy estimate for dhole was 0.41 with a detection probability of 0.65. We identified two individuals, and reported five predation events. We encountered a moderately high temporal overlap of dhole activity with that of barking deer (∆̂1= 0.65, CI = 0.42–0.83), human activity (0.63, 0.38–0.89), and livestock movement (0.59, 0.38–0.89). Given that dhole is a diurnal hyper-carnivore, illegal logging and tourism pressure appeared as major disturbances to the species' existence in the park. Habitats of northeastern protected forests, their adjacency with hill ranges of Tripura, and dhole being a habitat generalist, we conjecture its presence in the entire region and recommend thorough camera-trapping efforts.

Post-mortem genetic analyses may help to elucidate the cause of cardiac death. The added value is however unclear when a cardiac disease is already suspected or affirmed. Our aim was to study the feasibility and medical impact of post-mortem genetic analyses in suspected cardiomyopathy. We studied 35 patients with cardiac death and suspected cardiomyopathy based on autopsy or clinical data. After targeted sequencing, we identified 15 causal variants in 15 patients (yield 43%) in sarcomeric (n = 8), desmosomal (n = 3), lamin A/C (n = 3) and transthyretin (n = 1) genes. The results had various impacts on families, i.e. allowed predictive genetic testing in relatives (15 families), planned early therapeutics based on the specific underlying gene (5 families), rectified the suspected cardiomyopathy subtype (2 families), assessed the genetic origin of cardiomyopathy that usually has an acquired cause (1 family), assessed the diagnosis in a patient with uncertain borderline cardiomyopathy (1 family), reassured the siblings because of a de novo mutation (2 families) and allowed prenatal testing (1 family). Our findings suggest that post-mortem molecular testing should be included in the strategy of family care after cardiac death and suspected cardiomyopathy, since genetic findings provide additional information useful for relatives, which are beyond conventional autopsy.

Sirtuin 6 (SIRT6) plays a critical role in the progression and development of gastrointestinal cancers. However, the association between SIRT6 expression and clinicopathological parameters and prognosis in gastrointestinal cancer patients remains inconclusive. Consequently, we conducted this meta-analysis to evaluate the importance of SIRT6 expression in various types of gastrointestinal cancers. PubMed, EMBASE, and Web of Science databases were systematically searched to screen the relevant literature. The reported or estimated hazard ratio (HR) and odds ratio (OR) and their corresponding 95% confidence interval (CI) were pooled to assess the strength of the association. Nine studies involving 867 patients were included in the meta-analysis. Overall analysis showed that high SIRT6 expression was related to better overall survival in gastrointestinal cancers (HR = 0.62, 95% CI = 0.47–0.82). High SIRT6 expression was also related to a favorable tumor node metastasis (TNM) stage (OR = 0.44, 95% CI = 0.28–0.70) among gastrointestinal cancer patients. Our meta-analysis revealed that high SIRT6 expression might be a potential biomarker predicting better prognosis in gastrointestinal cancers, which may offer options for gastrointestinal cancer treatment.
Rezeption der Theorien von Heinz Guderian in polnischen militärwissenschaftlichen Zeitschriften vor dem Zweiten Weltkrieg
Authors: Fudalej Krzysztof
Published: May 2020

Heinz Guderian war zweifellos einer der wichtigsten deutschen Militärtheoretiker der Zwischenkriegszeit und später ein hervorragender Kommandant großer Panzerverbände. Er ist vor allem als Schöpfer der Panzertruppe als selbstständiger Truppengattung in die Geschichte eingegangen. Seine Theorien und Leistungen sind, zumindest in ihren Grundzügen, viel besser bekannt als die der anderen »Panzertheoretiker«. An seinem Beispiel wird gezeigt, wie gut deutsche, ständig wechselnde Ideen der Nutzung von Panzertruppen in polnischen militärwissenschaftlichen Zeitschriften vor dem Zweiten Weltkrieg rezipiert wurden.

Durch die Behandlung in sozialtherapeutischen Einrichtungen des Strafvollzuges kann die Wiederverurteilungsrate von Straftätern wirksam reduziert werden, jedoch werden nicht alle Straftäter, die sich hier bewerben, aufgenommen. Ziel der vorliegenden Studie ist die Untersuchung Betroffener hinsichtlich rückfallrelevanter Risikobereiche, allgemeinem Rückfallrisiko und Strafrestzeit. Zu diesem Zweck wurden von der Sozialtherapeutischen Anstalt Tegel abgelehnte (n= 26) und angenommene (n= 47) Bewerber miteinander verglichen. Es konnte gezeigt werden, dass abgelehnte Gefangene psychisch gesünder und beruflich besser situiert waren, aber auch vermehrt antisoziale und delinquenzfördernde Einstellungen aufwiesen, wodurch eine Ablehnung signifikant vorhergesagt werden konnte. Darüber hinaus konnten keine Unterschiede zwischen Abgelehnten und Angenommenen festgestellt werden, allerdings zeigte sich, dass fehlende Wohngruppenfähigkeit, Drogenkonsum und unpassende Strafrestzeit offiziell am häufigsten als Ablehnungsgründe genannt wurden. Die Indikationskriterien sozialtherapeutischer Einrichtungen werden diskutiert und die Entwicklung alternativer Behandlungsangebote für abgelehnte Straftäter empfohlen.
“Danger of a single story”: Pre-service teachers’ of color use of an online discussion board to discuss the essentialization of culture
Authors: Braunstein Lauren B. , Ozdemir Ozgur , Garcia Chad
Published: May 2020

The current demographic gap that exists between a predominantly white and female teacher force and an increasing diverse K-12 student population has prompted a focus on the recruitment and retainment of teachers of color. These recruitment and retainment efforts at times come at “the expense of preparation” (Gist, 2014, p. 266). Further, education scholars have critiqued teacher education due to the exclusion of the voices and experiences of pre-service teachers of color (Sleeter & Thao, 2007; Takimoto Amos, 2016). With the goal of improving the preparation of pre-service teachers of color, this article offers a concrete pedagogical strategy to build on the cultural and linguistic resources of pre-service teachers of color. In addition, the authors discuss how pre-service teachers of color enrolled in Diversity in Education course responded to the TED Talk Danger of a Single Story (Adiche, 2009). In response to the prompt “What do you wish people really knew about your identity”, three themes were illuminated: 1 – Resisting Essentializing, and Racializing Discourses, 2 – Hybrid Identities, 3 – Solidarity, and Community Building. The authors discuss how constructivist learning and culturally responsive pedagogies should be utilized to build equitable teacher education programs for all pre-service teachers. Additionally, best practices, recommendations, and strategies are included for the use of the online discussion boards as productive sites for critical thought.

In this article we introduce Tribonacci sequence spaces ℓp
(T) (1 ≤ p ≤ ∞) derived by the domain of a newly defined regular Tribonacci matrix. We give some topological properties, inclusion relation, obtain the Schauder basis and determine the α-, β- and γ-duals of the new spaces. We characterize the matrix classes on ℓp
(T). Finally, we give some geometric properties of the space ℓp
(T).
Estimating the distribution of a stochastic sum of IID random variables
Authors: Witkovský Viktor , Wimmer Gejza , Duby Tomas
Published: May 2020

Suggested is a non-parametric method and algorithm for estimating the probability distribution of a stochastic sum of independent identically distributed continuous random variables, based on combining and numerically inverting the associated empirical characteristic function (CF) derived from the observed data. This is motivated by classical problems in financial risk management, actuarial science, and hydrological modelling. This approach can be naturally generalized to more complex semi-parametric modelling and estimating approaches, e.g., by incorporating the generalized Pareto distribution fit for modelling heavy tails of the considered continuous random variables, or by considering the weighted mixture of the parametric CFs (used to incorporate the expert knowledge) and the empirical CFs (used to incorporate the knowledge based on the observed or historical data). The suggested numerical approach is based on combination of the Gil-Pelaez inversion formulae for deriving the probability distribution (PDF and CDF) from the associated CF and the trapezoidal quadrature rule used for the required numerical integration. The presented non-parametric estimation method is related to the bootstrap estimation approach, and thus, it shares similar properties. Applicability of the proposed estimation procedure is illustrated by estimating the aggregate loss distribution from the well-known Danish fire losses data.

Temperature-dependent dark-field scattering of single plasmonic nanocavity

Plasmonic materials have long been exploited for enhanced spectroscopy, integrated nanophotonic circuits, sensing, light harvesting, etc. Damping is the key factor that limits their performance and restricts the development of the field. Optical characterization of single nanoparticle at low temperature is ideal for investigating the damping of plasmons but is usually technically impractical due to the sample vibration from the cryostat and the surface adsorption during the cooling process. In this work, we use a vibration-free cryostat to investigate the temperature-dependent dark-field scattering spectroscopy of a single Au nanowire on top of a Au film. This allows us to extract the contribution of electron-phonon scattering to the damping of plasmons without performing statistics over different target nanoparticles. The results show that the full width at half-maximum of the plasmon resonance increases by an amount of 5.8%, over the temperature range of 5−150 K. Electromagnetic calculations reveal that the temperature-insensitive dissipation channels into photons or surface plasmon polaritons on the Au film contribute up to 64% of the total dissipations at the plasmon resonance. This explains why the reduction of plasmon linewidth seems small at the single-particle level. This study provides a more explicit measurement on the damping process of the single plasmonic nanostructure, which serves as basic knowledge in the applications of nanoplasmonic materials.

Exploring brain diversity in crustaceans: sensory systems of deep vent shrimps
Authors: Machon Julia , Krieger Jakob , Zbinden Magali , Ravaux Juliette , Harzsch Steffen
Published: May 2020

The current report focuses on shrimps from deep hydrothermal vents of the Mid-Atlantic Ridge that live in an environment characterized by high hydrostatic pressure, lack of sunlight, and with hot and potentially toxic emissions of black smoker vents. Malacostracan crustaceans display a large diversity of lifestyles and life histories and a rich repertoire of complex behavioral patterns including sophisticated social interactions. These aspects promote this taxon as an interesting group of organisms for those neurobiologists interested in evolutionary transformation of brain structures and evolutionary diversification of neuronal circuits. Here, we explore how analyzing the nervous system of crustacean species from extreme habitats can provide deeper insights into the functional adaptations that drive the diversification of crustacean brain structure.
