Combinatorics of KP hierarchy structural constants
Authors: Andreev A. , Popolitov A. , Sleptsov A. , Zhabin A. 
Published: December 2021

AbstractWe investigate the structural constants of the KP hierarchy, which appear as universal coefficients in the paper of Natanzon–Zabrodin arXiv:1509.04472. It turns out that these constants have a combinatorial description in terms of transport coefficients in the theory of flow networks. Considering its properties we want to point out three novel directions of KP combinatorial structure research: connection with topological recursion, eigenvalue model for the structural constants and its deformations, possible deformations of KP hierarchy in terms of the structural constants. Firstly, in this paper we study the internal structure of these coefficients which involves: (1) construction of generating functions that have interesting properties by themselves; (2) restrictions on topological recursion initial data; (3) construction of integral representation or matrix model for these coefficients with non-trivial Ward identities. This shows that these coefficients appear in various problems of mathematical physics, which increases their value and significance. Secondly, we discuss their role in integrability of KP hierarchy considering possible deformation of these coefficients without changing the equations on $$\tau $$
τ
-function. We consider several plausible deformations. While most failed even very basic checks, one deformation (involving Macdonald polynomials) passes all the simple checks and requires more thorough study.
Cosmic censorship, massless fermionic test fields, and absorption probabilities
Authors: Düztaş Koray 
Published: December 2021

AbstractIn the conventional approach, fermionic test fields lead to a generic overspinning of black holes resulting in the formation of naked singularities. The absorption of the fermionic test fields with arbitrarily low frequencies is allowed for which the contribution to the angular momentum parameter of the space-time diverges. Recently we have suggested a more subtle treatment of the problem considering the fact that only the fraction of the test fields that is absorbed by the black hole contributes to the space-time parameters. Here, we re-consider the interaction of massless spin (1/2) fields with Kerr and Kerr–Newman black holes, adapting this new approach. We show that the drastic divergence problem disappears when one incorporates the absorption probabilities. Still, there exists a range of parameters for the test fields that can lead to overspinning. We employ backreaction effects due to the self-energy of the test fields which fixes the overspinning problem for fields with relatively large amplitudes, and renders it non-generic for smaller amplitudes. This non-generic overspinning appears likely to be fixed by alternative semi-classical and quantum effects.
Reconstruction of DBI-essence dark energy with f(R) gravity and its effect on black hole and wormhole mass accretion
Authors: Kar Alokananda , Sadhukhan Shouvik , Debnath Ujjal 
Published: December 2021

In this paper, we have used the reconstructed Dirac–Born–Infeld (DBI)-essence dark energy density to modify the mass accretions of black holes and wormholes. In general, the black hole mass accretion does not depend on the metric or local Einstein geometry. That is why we have used a generalized mechanism by reconstructing the DBI-essence dark energy reconstruction with [Formula: see text] gravity. We have used some particular forms of the scale factor to analyze the accretion phenomena. We have shown the effect of cosmic evolution in the proper time variation of black hole mass accretion. Finally, we have studied the validity of energy conditions and analyzed the Type I–IV singularities for our reconstructed model.
High Expression of JMJD4 Is a Potential Diagnostic and Prognostic Marker of Renal Cell Carcinoma
Authors: Yan Hao , Bao Yewei , Lin Zongming 
Published: December 2021

Histone demethylase JMJD4 is a burgeoning tumor marker, which has been proven to be associated with colon cancer, but the role it plays in kidney cancer has not yet been investigated. In the present study, we evaluated whether JMJD4 can be a prognostic marker of patients with clear cell renal cell carcinoma (ccRCC) using data from public platform and in vitro experiments. Our results revealed that the expression of JMJD4 is higher in cancerous tissue than in normal tissues (

p
<
0.001

). High expression of JMJD4 is associated with a poor overall survival (OS) of ccRCC as compared with low expression of JMJD4 (

p
=
0.015

). JMJD4 showed significant relevance with M stage (

p

), gender (

p

), OS (0.018), disease-specific survival (DSS) (0.007), and percussion free interval (PFI) (0.041). Univariate and multivariate Cox analyses demonstrated that high JMJD4 expression had independent predictive value for OS in ccRCC patients (

From the importance of Englishin world of internationally communicated, the problems of learning management in each area seems to be differenced, language and culture are needed for recognizing, active learning is called for effectiveness instruction, and primary English teachers need to prepared in modern classroom. This research employed evaluative research to employ active learning for primary English teachers through professional program. Data were collected by setting a connoisseurship technique. Seven experts are appointed and read carefully a tentative program for primary English teachers. The connoisseurship technique allowed all experts share their experiences and ideas to promote active learning in freely. Video recording and note taking were recorded during the validation activity. Active learning program for primary English teachers is approved before implementation in different school contexts. The uncertainty situations, COVID-19 pandemic may be affected to schooling, teachers have to redesign lesson. The implementation though active online learning is needed to discuss and rethinking how it be effectively in authentic classroom.
Interactions between Jews and Christians in Later Medieval Provence
Authors: Smail Daniel Lord 
Published: December 2021

Abstract
This study uses an extensive body of archival evidence from Latin-Christian sources to explore economic and social interactions between Provençal Jews and Christians. Evidence discussed in section one indicates that the city’s Jewish and Christian communities interacted to a significant degree, and not just in the domain of moneylending. Data derived from a network analysis suggests that Jews were prominent in providing brokerage services. In the second section, analysis of a small sample of Jewish estate inventories indicates that the material profiles of Jewish and Christian families were very similar. In the third section, an analysis of a register of debt collection shows that Jews were involved in credit relations at a rate that was proportional to their population. Jewish moneylenders filled an economic niche by providing Christians with the liquidity to pay off structural debts generated by the political economy of rents and taxes.
A Century of Dialogue around Durkheim as a Founding Father of the Social Sciences
Authors: van Binsbergen Wim 
Published: December 2021

Abstract
In 2012 social scientists, philosophers and religious scientists celebrated the centennial of the publication of one of the most seminal books in the modern study of religion, Les formes élémentaires de la vie religieuse, by the then leading French sociologist Emile Durkheim’s (1858–1917); in 2017, we commemorated that author’s untimely death at age 59, broken by World War I in which he lost his only son and many of his beloved students. Educated, first as a Rabinnical student then as a modern philosopher, Durkheim earned his place among French thinkers primarily as a “founding father” of the social sciences. Having recently (on the basis of a life-long preoccupation) devoted a book-length study to Durkheim’s religion theory, I intend in this essay to highlight major aspects of Durkheim as an exponent of French thought. I shall first briefly situate Durkheim in his time and age, with special emphasis on his political views and his ethnic identity as a secularised Jew. Then I turn to Durkheim’s relation with the discipline in which he was originally trained, philosophy. I shall pay attention to the complex relationship between Durkheim and Kant and further highlight his dualism, epistemology, and views on primitive classification, as well as his puzzling realism, the place of emergence in his thought, and his moralist tendencies. I shall finally articulate Durkheim’s transition to sociology and how he gave over the torch of emerging sociology to his main students, having thus created an adequate context in which to discuss Durkheim’s final masterpiece (Les formes) and the still dominant theory of religion it expounds.
Foucault and Chomsky on Grammar and Governmentality
Authors: Barry Conor 
Published: December 2021

Abstract
This essay explores the use of the notions of grammar and governmentality in the work of Michel Foucault and Noam Chomsky. The goal is to exhibit the contrast but also mutual influence of these thinkers. Chomsky places his own linguistic theory in what he calls a tradition of Cartesian linguistics. Foucault’s presents an archaeology of general grammar in the French Classical Era. Chomsky and Foucault equally posit principles of governmentality. Both differ in terms of what they think the study of language brings to our understanding of ethical and political freedom. Governmental structure and grammatical structure, for Foucault, are always conventional, rather than essential – merely expressions of power dynamics. For Chomsky, the innate and natural human universality implied by underlying structures, in contrast, intimates a path to freedom from governmental coercion and oppression.
Media Consumption and News Literacy Habits During the covid-19 Pandemic

Abstract
The covid-19 pandemic disrupted political, economic, and social life in the United States beginning in March 2020, disproportionately affecting historically underrepresented groups. Media assumed unique roles during the pandemic, serving simultaneously as the gateway to work, education, social life, news, and public health information. Yet the covid-19 pandemic has been so challenged by misinformation that the World Health Organization declared it an infodemic. Because misinformation can prolong pandemics and increase deaths, news and media literacy can benefit society at large, especially vulnerable populations. The purpose of this descriptive study is to capture how undergraduates used media, how they obtained their news, and how they engaged news literacy skills during the covid-19 pandemic. A survey of over 900 undergraduate students showed that over two-thirds of respondents increased media use. Over half of respondents reported entertainment as their top reason for media use during the pandemic and reported news as their last reason. Respondents reporting previous exposure to news literacy education were significantly more likely to use most of the measured news literacy strategies. The findings of this study can support developing pandemic-responsive news and media literacy education which will be useful during future pandemics.

Published: December 2021

Objective A series of physiological changes in thyroid function occur during pregnancy and differ from those non-pregnant women. This study aimed to establish the pregnancy-specific reference intervals of TSH and FT4 using an indirect method based on the healthy pregnant women from southwest China population. Methods Thyroid function test results which available on the Laboratory Information System (LIS) were collected from the pregnancies who visited the Obstetric Clinic or the Department of Gynecology between 1 January 2015, and 30 December 2020. We grouped the data by trimesters to establish the reference intervals (RIs) based on the clinical consensus of different levels of TSH and FT4 at different weeks of gestation. All arrangements were referenced to the document CLSI EP28-A3C. Results A total of 33,040 thyroid function test results of pregnant women, aged 31 (28,33) years were statistical analyzed. Estimated RIs for TSH and FT4 in the first, second and third trimesters corresponding to the 2.5th and 97.5th percentiles in TPOAb negative were 0.02–5.23, 0.03–5.24, 0.37–5.68 mIU/L, 11.66–20.69, 10.1–18.59, 9.85–16.86pmol/L, respectively. Conclusion This study provides trimester-specific RIs for TSH and FT4 among healthy pregnant women in southwest China which guides clinicians to diagnosis and screen for thyroid disorders in this region.
Lumbar Flexion During Driving: Establishing a Methodology for Characterising Real-Time Posture Data Collected by Innovative Technology
Authors: Tinitali Sarah , Haines Terry , Bowles Kelly-Ann 
Published: December 2021

Objective To determine a methodology for the analysis of real-time driving posture data in the low back pain population. Background The strength of the relationship between driving posture and low back pain is yet to be defined due to the lack of studies in the field using validated and repeatable posture measurement tools. Reliable and validated real-time measurement tools are now available, yet reliable methods of analysis of these data are yet to be established. Method Ten occupational drivers completed a typical work shift while wearing an inertial motion sensor system (dorsaVi ViMove). Real-time lumbar flexion data were extracted, with test–retest reliability of mean lumbar flexion, peak lumbar flexion, and standard deviation of lumbar flexion analysed at different times across a work shift, and in different sections within a drive. Results Mean lumbar flexion was highly repeatable over numerous drives in one day, with greater test–retest reliability if the first five minutes of driving data were excluded. Peak lumbar flexion had acceptable test-retest reliability over numerous drives in one day, while standard deviation of lumbar flexion was not a repeatable measure. Conclusion Mean lumbar flexion was a reliable outcome for characterising driving posture in drivers with low back pain. Peak lumbar flexion may be used if appropriate to the individual study. Standard deviation of lumbar flexion is not a reliable posture outcome. Application This paper provides a reliable methodology for analysis of real-time driving posture data in occupational drivers with low back pain.
The Bubble of Normalisation: A Qualitative Study of Carers of People With Dementia Who Do Not Seek Help for a Diagnosis
Authors: Parker Michelle , Barlow Sally , Hoe Juanita , Aitken Leanne M. 
Published: December 2021

Objective Improving dementia diagnosis rates are a key feature of dementia strategy and policy worldwide. This study aimed to explore the experience of carers of people diagnosed with dementia during or following a hospital admission in order to identify factors that had prevented them from seeking help beforehand. Semi-structured interviews were conducted with 12 informal carers including adults caring for a parent, a friend or a spouse diagnosed with dementia between 2010–2019, following an acute hospital admission for a physical health problem, having not sought help previously. Main Findings Carers created a ‘bubble of normalisation’ around themselves and the person living with dementia (PLWD) to reject the label of dementia and protect the PLWD from a loss of independence, discrimination and prejudice they felt would be the result of a diagnosis. Carers struggled to talk to the PLWD about dementia reinforcing denial and stigma. Post-diagnosis carers felt unsupported and questioned the value of diagnosis. Principal Conclusions Stigma related to images of dementia as a disease that takes away independence and identity prevented discussion about dementia between carers and the PLWD. A lack of open discussion about memory concerns between health care professionals and carers also served to delay diagnosis.

Published: December 2021

Objectives: This study investigated the discriminative validity of various single or combined measurements of electroencephalogram (EEG) data, Conners’ Kiddie Continuous Performance Test (K-CPT), and Disruptive Behavior Disorder Rating Scale (DBDRS) to differentiate preschool children with ADHD from those with typical development (TD). Method: We recruited 70 preschoolers, of whom 38 were diagnosed with ADHD and 32 exhibited TD; all participants underwent the K-CPT and wireless EEG recording in different conditions (rest, slow-rate, and fast-rate task). Results: Slow-rate task-related central parietal delta (1–4 Hz) and central alpha (8–13 Hz) and beta (13–30 Hz) powers between groups with ADHD and TD were significantly distinct ( p < .05). A combination of DBDRS, K-CPT, and specific EEG data provided the best probability scores (area under curve = 0.926, p < .001) and discriminative validity to identify preschool children with ADHD (overall correct classification rate = 85.71%). Conclusions: Multi-method and multi-informant evaluations should be emphasized in clinical diagnosis of preschool ADHD.

Published: December 2021

Introduction Lumbar discectomy is a common and effective treatment for symptomatic disk herniation. It has been suggested that lumbar discectomy in older patients may result in poorer clinical outcomes and lesser satisfaction. The purpose of this study was to assess age-related difference in patient reported outcomes of patients undergoing lumbar discectomy for chronic low back and radicular pain. Materials and methods Patients with chronic lumbar radiculopathy without neurological deficit underwent non-urgent single level lumbar discectomy in our institution between 2014 and 2017. Pain level (using VAS score), Oswestry Disability Index, and SF-12 scores were retrospectively reviewed and compared between younger patients (<60 years, group 1) and older patients (>60 years, group 2). Results Seventy-three patients, aged between 34–76 years participated in this study. VAS, ODI, and SF-12 scores improved significantly after the surgery for each group ( P < .01). When comparing between the groups, no significant differences in the outcomes measured were found after the surgery in both early post-operative follow-up and late post-operative follow-up ( P > .05). Discussion Elderly patients undergoing lumbar discectomy report a significant reduction in VAS, ODI, and SF-12 scores justifying the procedure. Conclusion Lumbar discectomy improved function and decreased pain level to similar extent in both younger and older patients suffering from radicular symptoms related to lumbar disc herniation.

Abstract
Purpose
We report a case of intravascular lymphoma with primary vitreoretinal lymphoma-like fundus findings.

Case
A 61-year-old man with a one-week history of temporal visual field defect in the left eye was referred by a local ophthalmologist to our department. A yellowish-white raised patchy lesion was found in the nasal fundus of the left eye. Vitreoretinal lymphoma was suspected, and vitrectomy was performed in the left eye for diagnostic purpose. However, vitreous interleukin-10 concentration was low and no significant result was obtained. He had fever of around 38 °C, and respiratory failure that started 2 weeks before ophthalmological examination, worsened. Intravascular lymphoma was diagnosed from the results of histopathological examinations of transbronchial lung biopsy, bone marrow biopsy and random skin biopsy. With the start of systemic chemotherapy, the subretinal lesions shrank gradually and systemic condition was stable. However, 5 months after the start of chemotherapy, spread to the central nervous system was observed, and chimeric antigen receptor T cell (CAR-T) therapy was started in another hospital. After the start of CAR-T therapy, the subretinal lesions shrank further.

Conclusions
Intravascular lymphoma may be accompanied by primary vitreoretinal lymphoma-like intraocular lesions. If intraocular lesions are accompanied by systemic symptoms such as fever of unknown origin, the possibility of intravascular lymphoma should be suspected and systemic work-up should be performed.
