Published: June 2023

The first floristic study of the historical monumental cemetery of San Cataldo in Modena (N-Italy) is presented. The research was performed in the period 2019–2022, considering only spontaneous individuals growing within the historical area (4.8 ha). A total of 266 taxa (species and subspecies) was found, of which 1 new for the flora of Italy (Malus × robusta ‘John Downie’), 2 new for the administrative region of Emilia-Romagna (Calocedrus decurrens and Salvia haematodes) and 1 new for the province of Modena (Epilobium ciliatum). Therophytes prevail (37.6%), followed by hemicryptophytes (31.6%), phanerophytes (16.2%) and geophytes (11.7%). The chorological spectrum is dominated by Eurasian species (32.0%), followed by Mediterranean (26.3%), Cosmopolitan (24.8%), Boreal (6%) and N-American (4.5%) ones. Allochthonous species are 16.5% of the list, with neophytes always prevailing over archaeophytes (28 vs. 9 species). Invasive species are 67.8% of the neophytes; on a regional scale they are 1.5% of the list. Protected species are 2.6% of the total; 3 of them are internationally protected and 2 are included in the red list of Italian flora. This study confirms the great biological richness of urban environments and the potential of historical cemeteries as a refugium for the conservation of species that have become rare, endangered or infrequent at a regional or national level, because of the heavy human impact on the territory.

A new species of freshwater mussel belonging to the genus Pseudocuneopsis, namely Pseudocuneopsis yangshuoensissp. nov., is diagnosed and described from Guangxi Province, China. This paper provides a detailed morphological description, photograph of the type specimen, and anatomical characteristics along with partial sequences of mitochondrial COI as DNA barcode data for this novel species. The new species can be distinguished from its congeners (Pseudocuneopsis sichuanensis and Pseudocuneopsis capitata) by shell shape, beak position and surface sculpture. The interspecies genetic distance based on the COI barcode between P. yangshuoensissp. nov. and P. sichuanensis is 8%, while it reaches 9% with P. capitata. Therefore, we provide robust morphological and molecular evidence to support the validity of this new species.
A Filippov tumor-immune system with antigenicity
Authors: Peng Hengjie , Xiang Changcheng
Published: June 2023

A threshold strategy model is proposed to demonstrate the extinction of tumor load and the mobilization of immune cells. Using Filippov system theory, we consider global dynamics and sliding bifurcation analysis. It was found that an effective model of cell targeted therapy captures more complex kinetics and that the kinetic behavior of the Filippov system changes as the threshold is altered, including limit cycle and some of the previously described sliding bifurcations. The analysis showed that abnormal changes in patients' tumor cells could be detected in time by using tumor cell-directed therapy appropriately. Under certain initial conditions, exceeding a certain level of tumor load (depending on the patient) leads to different tumor cell changes, that is, different post-treatment effects. Therefore, the optimal control policy for tumor cell-directed therapy should be individualized by considering individual patient data.
$ (s, S) $ Inventory policies for stochastic controlled system of Lindley-type with lost-sales
Authors: Blancas-Rivera Rubén , Cruz-Suárez Hugo , Portillo-Ramírez Gustavo , López-Ríos Ruy
Published: June 2023

This paper presents a characterization of $ (s, S) $-inventory policies for Lindley systems with possibly unbounded costs, where the objective is to minimize the expected discounted total cost by ordering (production) strategies. Moreover, the existence of a subsequence of minimizers of the value iteration functions that converge to a $ (s, S) $ optimal inventory system policy is shown. A numerical example is given to illustrate the theory.
Sociabilités de jeunes filles dans l’œuvre de Gustave Flaubert
Authors: Reverzy Éléonore
Published: June 2023

Dans « Sociabilités de jeunes filles dans l’œuvre de Flaubert », on s'efforce de penser l'isolement et la singularité de la jeune fille dans le roman flaubertien. Passant par les avant-textes, on s'aperçoit que cet isolement n'était, pour Emma comme pour Félicité, pas si complet et que Flaubert a travaillé à désocialiser son personnage. Louise Roque, avec sa grâce de jeune bête sauvage, inscrit, à la suite d'Emma, aussi la révolte.

Behavior of Reinforced Concrete Beams Strengthened in Negative Moment Region Using CFRP Plates
Authors: Gawad Aly Salah Abdel
Published: June 2023

One possible method for strengthening deteriorated concrete structures is to externally bond composite material plates to the concrete. The use of Carbon Fiber Reinforced Polymer (CFRP) laminates as an effective and versatile technique for strengthening reinforced concrete (RC) structures has developed into a sizable industry in recent years. To implement such rehabilitation, the nature of the bond between the composite plate and the concrete must be understood. The behavior of reinforced concrete beams strengthened in the negative moment region using CFRP strips is presented in this paper. The experimental program included strengthening and testing five half-scale, reinforced, simply supported rectangular cross section beams with an overhanging (cantilever) portion. One of the tested specimens was tested without any strengthening and considered as the control specimen. The rest specimens were strengthened with CFRP strips using different technique and then tested until complete failure. The effect of strengthening technique on deflection, failure load, strain, failure mode, and ductility are discussed. In addition, and due to local stress concentration at the plate ends, the influence of different type of CFRP fixation at both ends for proper bonding of the strips, and the strengthening pattern on the behavior of beams was examined. The ratio of absorbed energy at failure to total energy, or energy ratio, was used as a measure of beam ductility. The results generally indicate that the flexural strength of the strengthened beams is increased. It is also noted that, in addition to the longitudinal CFRP plates, the fiber oriented in the vertical direction forming a C or U-shape around the beam cross section significantly reduce beam deflections and increase beam load carrying capacity. However, all the strengthened beams experienced semi brittle failure, mandating a higher factor of safety in design. The results also indicate that plating reduced crack size in the beams and somewhat reduced their ductility.
Sobre la posición filogenética de un ejemplar particular de Panochthus (Xenarthra, Glyptodontidae): análisis basado exclusivamente en caracteres de la coraza dorsal
Authors: Zamorano Martín
Published: June 2023

On the phylogenetic position of a particular specimen of Panochthus (Xenarthra, Glyptodontidae): an analysis based exclusively on characteristics of the dorsal carapace. The monophyly of Xenarthra is supported by morphological and molecular characters, ancient DNA and collagen. Phylogenetic work also supports the idea of a common ancestor for the Cingulata; Glyptodontidae is considered a natural group too; this also occurs with the genus Panochthus, which includes eight species. The phylogenetic relationships of a peculiar specimen UATF-V s/n, assigned to Panochthus sp. were examined through a cladistic analysis carried out exclusively with characters from the dorsal carapace. A maximum parsimony tree with L = 49, CI = 0.84 and IR = 0.74 was obtained through the analysis of a matrix of 14 taxa and 29 characters. The cladogram comprises two large groups: node A includes Nopachtus coagmentatus, N. cabrerai, Propanochthus bullifer, Phlyctaenopyga ameghini; and node B contains Glyptodon reticulatus, Hoplophorus euphractus, Neosclerocalyptus ornatus, Panochthus intermedius, P. subintermedius, P. tuberculatus, P. greslebini, P. hipsilis and UATF-V s/n. The specimen UATF-V s/n is positioned as the sister taxon of all Panochthus spp., having most plesiomorphic characters than other species of the genus. Glyptodon reticulatus appears as the sister group of Panochthus, presenting osteoderms of the mid-dorsal region with a reticular pattern. The characteristic of these osteoderms without a central figure is shared with G. reticulatus and Neuryurus trabeculatus; this feature is interpreted as an evolutionary convergence. The exclusive feature of Panochthus is that the mid-dorsal region and the anterior part of the mid-lateral region of the dorsal carapace are formed by ornate osteoderms following a reticular pattern. Keywords: Glyptodontidae, Panochthus, phylogeny, dorsal carapace, osteoderms, reticular pattern.

Published: June 2023

Objectives:

This research aimed to compare the incidence and severity of acute appendicitis (AA) before and during the COVID-19 pandemic.

Materials and Methods:

Two southern Saudi Arabian high-volume hospitals hosted this retrospective investigation. The COVID pandemic period (March–June 2020) and the pre-COVID period were identified (March–June 2019). The frequency, clinical manifestation, and severity of AA were compared for patients who underwent appendectomies during these periods.

Results:

In the study hospitals, total admissions decreased by 52.3% (95% confidence interval [CI]: 51.1%–53.3%) from 6231 patients during the pre-COVID period to 3261 patients during the COVID period. In the 2019 study period, 107 cases of AA were surgically treated, compared to 61 cases in 2020. The observed reduction rate was 57.1% (95% CI: 47.5%–66.8%). During the COVID period, the duration from the onset of symptoms to hospital admission and hospital admission to surgery was significantly shorter for patients. There were no significant differences between the COVID and pre-COVID periods in terms of the clinical picture or severity of AA.

Conclusions:

During the COVID era, there was a significant decrease in the number of AA patients hospitalized, which may indicate the efficacy of home treatment for mild cases. The successful measures taken by the Saudi Arabian government during the curfew, along with the optimal utilization of resources and logistics, resulted in the early presentation and management of AA, yielding results comparable to the pre-COVID era.
Coccinia Indica Leaf Extract Inhibits Herpes Simplex 2 Viruses' Propagation In vitro
Authors: Chandramoorthy Harish Chinna Konda
Published: June 2023

Background:

Herpes simplex virus-2 (HSV-2) is known to cause genital herpes a well-characterized sexually transmitted disease among humans. Although there are a couple of antiviral drugs available, poor adherence toward the treatment makes it more complicated. Recent reports on HSV drug resistance due to mutations have paved the way for the search of new antivirals required to control rising new virus infections.

Objectives:

The objective of this study was to screen the antiviral property of Coccinia indica ethanolic leaf extracts over the HSV-2 strain.

Subjects and Methods:

C. indica ethanolic extracts were assessed for anti-HSV-2 properties by the standard in vitro microtissue culture assay.

Results:

The results presented the least concentration of 75 μg of C. indica ethanolic leaf extract inhibited 100% of HSV-2 propagation and 50 μg inhibited around 60% of virus and showed a residual titer of 100.8 ± 0.04 at day 5.

Conclusion:

The C. indica ethanolic extracts exhibited a significant antiviral activity against the HSV-2 virus in vitro.
Simplicial generation of Chow rings of matroids
Authors: Backman Spencer , Eur Christopher , Simpson Connor
Published: June 2023

We introduce a presentation of the Chow ring of a matroid by a new set of generators, called “simplicial generators.” These generators are analogous to nef divisors on projective toric varieties, and admit a combinatorial interpretation via the theory of matroid quotients. Using this combinatorial interpretation, we (i) produce a bijection between a monomial basis of the Chow ring and a relative generalization of Schubert matroids, (ii) recover the Poincaré duality property, (iii) give a formula for the volume polynomial, which we show is log-concave in the positive orthant, and (iv) recover the validity of Hodge–Riemann relations in degree 1, which is the part of the Hodge theory of matroids that currently accounts for all combinatorial applications of the work of Adiprasito et al. (2018). Our work avoids the use of “flips,” the key technical tool employed in that work.
A note on pseudorandom Ramsey graphs

Nonuniqueness in law of stochastic 3D Navier–Stokes equations
Authors: Hofmanová Martina , Zhu Rongchan , Zhu Xiangchan
Published: June 2023

We consider the stochastic Navier–Stokes equations in three dimensions and prove that the law of analytically weak solutions is not unique. In particular, we focus on three examples of a stochastic perturbation: an additive, a linear multiplicative and a nonlinear noise of cylindrical type, all driven by a Wiener process. In these settings, we develop a stochastic counterpart of the convex integration method introduced recently by Buckmaster and Vicol. This permits us to construct probabilistically strong and analytically weak solutions defined up to a suitable stopping time. In addition, these solutions fail to satisfy the corresponding energy inequality at a prescribed time with a prescribed probability. Then we introduce a general probabilistic construction used to extend the convex integration solutions beyond the stopping time and in particular to the whole time interval

[0,\infty)

. Finally, we show that their law is distinct from the law of solutions obtained by Galerkin approximation. In particular, nonuniqueness in law holds on an arbitrary time interval

Crustal Anisotropy from the Birefringence of P-to-S Converted Waves: Bias Associated with P-Wave Anisotropy
Authors: Park Jeffrey , Chen Xiaoran , Levin Vadim
Published: June 2023

Many researchers have used the birefringence of P‑to‑S converted waves from the Moho discontinuity to constrain the anisotropy of Earth’s crust. However, this practice ignores the substantial influence that anisotropy has on the initial amplitude of the converted wave, which adds to the splitting acquired during its propagation from Moho to the seismometer. We find that large variations in Ps birefringence estimates with back-azimuth occur theoretically in the presence of P‑wave anisotropy, which normally accompanies S‑wave anisotropy. The variations are largest for crustal anisotropy with a tilted axis of symmetry, a geometry that is often neglected in birefringence interpretations, but is commonly found in Earth’s crust. We simulated globally-distributed P‑coda datasets for 36 distinct 4‑layer crustal models with combinations of elliptical shear anisotropy or compressional anisotropy, and also incorporated the higher-order anisotropic Backus parameter C. We tested both horizontal and tilted symmetry-axis geometries and tested the birefringence tradeoff associated with Ps converted phases at the top and bottom of a thin high‑ or low‑velocity basal layer. We computed composite receiver functions (RFs) with harmonic regression over back azimuth, using multipletaper correlation with moveout corrections for the epicentral distances of 471 events, to simulate a realistic data set. We estimate Ps birefringence from the radial and transverse RFs, a strategy that is similar to previous studies. We find that Ps splitting can be a useful indicator of bulk crustal anisotropy only under restricted circumstance, either in media with no compressional anisotropy, or if the symmetry axis is horizontal throughout. In other, more-realistic cases, the inferred fast polarization of Ps birefringence estimated from synthetic RFs tends either to drift with back-azimuth, form weak penalty-function minima, or return splitting times that depend on the thickness of an anisotropic layer, rather than the birefringence accumulated within it.
Educational tools to dismantle disparities by addressing social determinants of health
Authors: Diaz-Cruz Edgar , Long Stephanie
Published: June 2023

Background: Social determinants of health (SDOH) are personal, social, economic, and environmental factors that contribute to health disparities in the United States.   
Objectives: To develop educational interventions to teach and assess students’ knowledge about health disparities using a SDOH framework, and design assessment methods to identify theory-based interventions to improve patient health outcomes.   
Methods: Educational tools utilising a SDOH framework were designed for students to learn about health disparities. A socio-ecological model allowed students to assess multi-level determinants of health and propose more effective interventions. Evidence-based questions were designed to address the health of a specified population. A case study allowed students to apply therapeutic knowledge and clinical interventions to improve patient health.
Results: Exactly 44 students enrolled in three iterations of the course and completed pre- and post-surveys. Upon completion, students’ perception of health disparities significantly increased.   
Conclusion: The SDOH model offers strategies for other pharmacy programs seeking to increase public health-related topics. Students can develop skills to directly apply to a current problem and then build theory to engage in problem-solving. This innovative approach utilising SDOH for pharmacy students positively impacted awareness and knowledge.

Bali is known worldwide for most of its people's activities using handicrafts; one of the most commonly found arts and crafts is Balinese ornaments. Ornaments are very well developed, not only to decorate temples, but also to decorate traditional houses, and tourism commodity needs. Some Balinese ornaments symbolically have particular meanings and symbolize something based on culture, customs, beliefs, and also religion. Understanding the form and function of Balinese ornaments is very important to improve knowledge and services to the community, not only locally, nationally, but also internationally. To overcome this, Balinese ornaments need to be developed comprehensively and holistically, especially to improve practical and theoretical knowledge. The art-based research method is to introduce the finished ornament drawing or drawing in stages, and the introduction of its function. Therefore, this research is important to improve the understanding of ornaments. Some of the ornaments discussed are keketusan (independent loose shapes), pepatran (vines), kekarangan (stylization of the faces of living beings), and wayang. An understanding of ornaments can improve artistic insight, especially in the application of the form and function of Balinese ornaments. It is expected that Balinese ornaments will continue to develop in form and function following the times to answer the needs of local and global art.
Assessing The Key Physical Capabilities in Striking Combat Sports: Reliability And Reproducibility of A New Test
Authors: Gusciglio Baptiste , Morin Jean-Benoit
Published: June 2023

The rules and the technical aspect of combat sports make it difficult to determine key performance indicators. Therefore, the assessment of striking sports discipline-specific key components may be relevant. This study aims to present a test assessing specifically the fighters striking force-velocity (F-V) capabilities. 10 MMA fighters performed FV (two-point (TP) and multiple-point (MP) methods) and fatigue tests using the landmine punch exercise (LPE) which is considered a specific exercise for striking combat sports. A high within-subject intra-session and inter-session reliability and reproducibility were found for the FV profiles parameters and the fatigue test (most CVs<10%, ICCs>0.67, ES < 0.2 for F0, V0, Pmax, Sfv, Ppeak, Pmean, Pmin and FI%  and r > 0.9). Moreover, the TP and MP methods showed high validity and agreement (r >0.88 and ES <0.37). The novel LPE test presented in this pilot study is a highly reproducible tool for evaluating both mechanical and anaerobic components specific to the discipline. Athletes and coaches may use this test to better understand striking performance in combat sports.

The Effects of Cannabidiol and Serotonin on Anxiety-Like Behavior in Crayfish
Authors: Knight Hannah , Chamberlain Katie
Published: June 2023

Cannabidiol (CBD) is a cannabinoid that is being used as a new treatment for many mental and physical medical conditions, including anxiety. Serotonin (5-HT) is a neurotransmitter that has been shown to have many roles, including stabilizing mood. Crayfish are invertebrate animals that have been used as a model system to study human diseases. Crayfish are well suited to study the effect of CBD on anxiety due to their documented endocannabinoid system and anxiety-like behavioral traits. In this study, the effects of CBD on anxiety-like behavior in crayfish were investigated using a Light-Dark maze as a behavioral analysis tool. At the doses used, CBD did not independently show any influence on either the Light-Dark preference or the total position moves made by crayfish. 5-HT showed quite variable results compared to the saline solution. 5-HT injection significantly decreased time spent in the dark for crayfish injected with 2µg/g of CBD and significantly decreased movement for crayfish injected with 4µg/g of CBD. The dichotomous behavior of the 5-HT injected crayfish requires more study to determine if underlying factors can explain the varying responses. The concentrations of CBD may also need to be increased to properly examine its role in reducing anxiety.
A Feminist Dialogic Reading of the New Woman: Love, Female Desire, and Family in The Virgin and the Gypsy by D. H. Lawrence and in The Tragedy of Demetrio by Hanna Mina
Authors: Kortas Cyrine
Published: June 2023

This paper explores the depiction of female characters as New Women in a comparative analysis of two selected short stories by two seemingly anti-feminist authors; D. H. Lawrence in England and Hanna Mina in Syria. I argue that these short stories signal the need for a new perspective, analyzing how these two authors challenged the conventional fictional treatment of womanhood and created complex female heroines struggling against restrictive social roles and values. Examining these selected narratives, “The   Virgin and the Gypsy” by D. H. Lawrence and in “The Tragedy of Demetrio” by Hanna   Mina, sets forth an unexpected area of comparison between English and Arabic literature with a specific interest in the construction of New Woman identity at the turn of the century, namely the fragmented and complex presentations of the heroines’ inner struggle between the traditional female roles and their aspirations for a freer, more fluid identity. A close reading will, therefore, bring out certain similarities in terms of themes and style that call for a Bakhtinian insight into dialogism to account for the fragmented character of the New Woman in both texts.

Reading Patterns, Scanning and the ‘Control F’/Search Icon: How Students Really (Don’t) Read
Authors: Safa Nehme , Dakakni Deema
Published: June 2023

Purpose: The purpose of this research was to investigate whether digital reading had an impact on reading skills, as well as students’ tendencies to read online or offline in the L2 English speaking classroom.
Approach/Methodology/Design: This quantitative-qualitative mixed methods case study involved was comprised of a convenient, purposive sample of 16 participants for semi structured focus group interviews in an English-speaking private university.
Findings: The findings seem to suggest that reading digitally prods students not only to adopt skimming patterns, but to use the “Control F” command to bypass reading altogether. Furthermore, students’ reading preferences for online/offline material was also revealed, showing a significant tendency of students to revert to online material “just to understand” or “get an idea” while deep understanding was substantially associated with preference for offline reading.
Practical Implications: The findings of this study may serve to guide teachers of English in the L2 classroom how to navigate online texts comprehensively, what skills to promote while reading online and which to forgo.
Originality/value: This study sheds light on the possible misuse of “Control F” during online reading exercises and underscores the necessity of using this tool over and above reading strategies and skills, and not as a stand-alone tool in itself,

A INFLUÊNCIA DO DIREITO INTERNACIONAL DO TRABALHO NO DIREITO DO TRABALHO BRASILEIRO

Published: June 2023

O trabalho, na acepção da palavra, sempre esteve relacionado à própria existência do ser humano, por muito mais do que a mera subsistência, ele representa, sobretudo, um fator de satisfação e realização pessoal, além de trazer dignidade àquele que o exercita. No desenvolvimento do presente estudo, partiu-se do pressuposto inicial da análise com relação à influência do direito internacional do trabalho no direito do trabalho brasileiro, percorrendo pelos instrumentos previstos no tratamento do direito do trabalho em âmbito nacional e internacional, bem como, seus aspectos jurídicos, sociais e históricos. Além dos direitos trabalhistas previstos na Constituição Federal e na legislação ordinária, principalmente na CLT (Consolidação das Leis do Trabalho), encontram-se outros direitos trabalhistas advindos das convenções da OIT (Organização Internacional do Trabalho). O direito internacional teve papel fundamental nesse desenvolvimento; através da ratificação da Convenção e da Organização Internacional do Trabalho, iniciou-se um efetivo processo, sendo que tais órgãos influenciaram na legislação nacional, tendo seus conceitos, princípios e prerrogativas inseridas na Constituição Federal e em demais leis no sentido de aumentar a proteção ao trabalhador. Isto é um avanço normativo considerável quanto à legislação social laboral, foi a internacionalização das normas trabalhistas que impeliu a uma crescente busca, no plano internacional, de harmonização da proteção do trabalhador. O debate sobre direitos humanos e direitos dos trabalhadores tem aumentado, no Direito Internacional, especialmente, porque se tem pretendido, em alguns fóruns, como a OMC (Organização Mundial do Comércio), por exemplo, vincular os direitos humanos no trabalho às questões de comércio internacional.
