Review of Suppes 1957 Proposals For Division by Zero
Authors: Anderson James , Bergstra Jan 
Published: June 2021

We review the exposition of division by zero and the definition of total arithmetical functions in ``Introduction to Logic" by Patrick Suppes, 1957, and provide a hyperlink to the archived text. This book is a pedagogical introduction to first-order predicate calculus with logical, mathematical, physical and philosophical examples, some presented in exercises. It is notable for (i) presenting division by zero as a problem worthy of contemplation, (ii) considering five totalisations of real arithmetic, and (iii) making the observation that each of these solutions to ``the problem of division by zero" has both advantages and disadvantages -- none of the proposals being fully satisfactory.
We classify totalisations by the number of non-real symbols they introduce, called their Extension Type. We compare Suppes' proposals for division by zero to more recent proposals. We find that all totalisations of Extension Type 0 are arbitrary, hence all non-arbitrary totalisations are of Extension Type at least 1. Totalisations of the differential and integral calculus have Extension Type at least 2. In particular, Meadows have Extension Type 1, Wheels have Extension Type 2, and Transreal numbers have Extension Type 3.
It appears that Suppes was the modern originator of the idea that all real numbers divided by zero are equal to zero. This has Extension Type 0 and is, therefore, arbitrary.
Majority Colorings of Sparse Digraphs
Authors: Anastos Michael , Lamaison Ander , Steiner Raphael , Szabó Tibor 
Published: June 2021

A majority coloring of a directed graph is a vertex-coloring in which every vertex has the same color as at most half of its out-neighbors. Kreutzer, Oum, Seymour, van der Zypen and Wood proved that every digraph has a majority $4$-coloring and conjectured that every digraph admits a majority $3$-coloring. They observed that the Local Lemma implies the conjecture for digraphs of large enough minimum out-degree if, crucially, the maximum in-degree is bounded by a(n exponential) function of the minimum out-degree.
Our goal in this paper is to develop alternative methods that allow the verification of the conjecture for natural, broad digraph classes, without any restriction on the in-degrees. Among others, we prove the conjecture 1) for digraphs with chromatic number at most $6$ or dichromatic number at most $3$, and thus for all planar digraphs; and 2) for digraphs with maximum out-degree at most $4$. The benchmark case of $r$-regular digraphs remains open for $r \in [5,143]$.
Our inductive proofs depend on loaded inductive statements about precoloring extensions of list-colorings. This approach also gives rise to stronger conclusions, involving the choosability version of majority coloring.
We also give further evidence towards the existence of majority-$3$-colorings by showing that every digraph has a fractional majority 3.9602-coloring. Moreover we show that every digraph with large enough minimum out-degree has a fractional majority $(2+\varepsilon)$-coloring.

Authors: Ciptaningtyas Vincentia Rizke , De Mast Quirijn , De Jonge Marinus Isaäk 
Published: June 2021

Introduction: Lower respiratory tract infections (LRTI) are a substantial threat for children worldwide. Currently, there is a lack of knowledge about the burden and etiology of LRTI in children under five years of age in Indonesia.
Methodology: We have systematically searched the available English and Indonesian scientific literature to review and summarize data on LRTI and LRTI-associated invasive disease, and bacterial carriage in the upper respiratory tract in children under five years of age in Indonesia.
Results: Overall, data on the burden and etiology of LRTI in children under five years of age in Indonesia is very limited. The data are primarily collected in Java. Data from other parts of Indonesia, including Sumatra, Kalimantan, and Sulawesi, are scarce. The case fatality rate (CFR) of LRTI in children under five years of age in Indonesia was 0.11%. Influenza was the most commonly reported viral etiological agent of LRTI in children under five years of age in Indonesia. Klebsiella pneumoniae was the most frequently reported bacterial agent of LRTI. Streptococcus pneumoniae showed the highest carriage rates.
Conclusions: Surveillance and diagnostic studies are urgently needed and should be conducted in different parts of Indonesia to improve insight in the burden and etiology of LRTI in Indonesia. These data are pivotal to increase the effectiveness of public health strategies, including vaccination and prevention of antimicrobial resistance.
Étude du lexique et des catégories zoologiques en vietnamien
Authors: Nguyen Phuong Duyen , Zucker Arnaud , Do-Hurinville Danh-Thành 
Published: June 2021

Cet article a pour objectif de présenter le système de dénomination des animaux en vietnamien. Il exploite essentiellement l’onomastique zoologique présente dans Trésor des contes vietnamiens (Nguyen Dong Chi), recueil de contes folkloriques souvent anciens, qui constitue le corpus d’un travail de thèse en cours. Il s’agit d’une analyse linguistique de la terminologie zoonymique vietnamienne qui présente les deux caractéristiques suivantes : i) un riche éventail de zoonymes, composés principalement de noms monosyllabiques, mais aussi de locutions complexes (polysyllabiques) ; ii) l’existence de termes génériques larges, antéposés au zoonyme, qui construisent des classes linguistiques.
La création d’entreprise, remède aux maux du travail salarié ?
Authors: Landour Julie 
Published: June 2021

Apparu en France dans les années 2010, le phénomène des Mompreneurs (pour « mamans entrepreneures ») repose sur la triple promesse d’une conciliation de la vie professionnelle et familiale, d’une souplesse plus grande dans l’aménagement des temps du travail, d’une indépendance nouvelle capable de donner ou redonner du sens à un travail salarié souvent vécu dans la souffrance. L’article, à partir d’une série d’entretiens avec des « mompreneurs », fait le point sur le passage des attentes à la réalité : qu’en est-il de la conciliation entre vie familiale et professionnelle ? L’indépendance à l’égard d’un patron ne se paie-t-elle pas de nouvelles dépendances à l’égard des client∙e∙s (qu’il faut chercher, qu’il faut satisfaire) ? Les protections liées au salariat ne se révèlent-elles pas mieux assurées que les gains d’une indépendance moins vécue que rêvée ?
Les relations économiques entre la France et le comté de Namur aux Temps modernes
Authors: Ronvaux Marc 
Published: June 2021

Le petit comté de Namur, qui fait partie des Pays-Bas espagnols puis autrichiens, est du point de vue géographique étroitement imbriqué dans les souverainetés voisines de la France, mais aussi de Liège, ce qui en fait un bon champ d’observation du protectionnisme mercantiliste. Les échanges, qui traversent principalement par la Meuse et la Sambre, des frontières inextricables et changeantes, sont compliqués par la rivalité de trois pouvoirs, mais le réalisme des acteurs économiques l’emporte dans un contexte de guerres fréquentes et d’occupations. Cette proximité favorise aussi un afflux massif de numéraire étranger dans le comté, ce qui pose des problèmes où une souveraineté monétaire précaire se heurte aux exigences des acteurs économiques. Les sources, essentiellement fiscales, révèlent des importations namuroises de vin, d’ardoises, d’écorces pour la tannerie, de bois et de charbon de bois ; s’y ajoutent quelques produits de luxe. Dans l’autre sens, le comté exporte du fer, de la houille, des armes, des clous et du bétail. Finalement, sauf en ce qui concerne la tannerie, où Namur et Givet sont rivales, les rapports sont moins faits de concurrence que de complémentarité.
Entre dispersion et centralité : l’invention du sujet dans les Essais
Authors: de Lajarte Philippe 
Published: June 2021

Ce qui s’annonce, dans l’affirmation de Montaigne, au début du chapitre Du repentir , qu’il est le premier auteur de son temps à se « communiquer » par son « estre universel », c’est l’invention d’un sujet d’un type nouveau. Ce sujet, ce n’est pas, quelque importante que soit la place qu’il y occupe, le moi empirique que les Essais s’appliquent à déchiffrer : c’est le sujet que ces derniers construisent dans et par leur discours. Sujet qui s’appréhende sous deux aspects opposés mais étroitement complémentaires : la dispersion, caractéristique du discours montaignien considéré du point de vue de ses énoncés, et la centralité, caractéristique de ce même discours en tant que procès d’énonciation.
Jean de Tournes, Sébastien Gryphe et Robert Granjon à Lyon en 1543 et après
Authors: Kemp William 
Published: June 2021

Cet article est basé sur une étude des premières éditions de Jean I de Tournes, celles de l’année 1543. Les résultats sont présentés dans l’annexe de l’article. Trois conclusions se dégagent de l’étude. Première conclusion : De Tournes a employé un caractère romain plutôt petit de 9 points [R 65 mm par 20 lignes] pour toutes les éditions dont j’ai pu consulter un exemplaire. Ce caractère, le premier gravé par Robert Granjon selon le travail du regretté Hendrik Vervliet, fut initialement employé en 1542 par l’ancien patron de Jean de Tournes, Sébastien Gryphe, pour l’impression d’une série de Bibles latines en format in-16. Deuxièmement, dans la moitié de ces éditions De Tournes de 1543, il y avait aussi sur les pages de titre un caractère qui n’était pas attendu, un petit-canon romain d’environ 27 points [R 190 mm]. Selon les relevés de Vervliet, ce caractère est apparu chez De Tournes en 1547. De plus, à part une occurrence en 1544, ce caractère n’a pas été utilisé par De Tournes en 1544, 1545 et 1546. Les autres plus gros caractères employés dans les titres ont aussi été considérés. Comment interpréter ? Ce petit-canon aurait-il été une lettre de démonstration ou un caractère « spécimen » lui permettant de montrer ses talents de graveur par une lettre de prestige, qui était destinée à être employée sur les pages de titres ou dans les préliminaires ? On peut se demander si une telle conjoncture n’implique pas la présence de Granjon à Lyon en 1542 et/ou 1543. Ainsi, au début de sa carrière, Granjon a suivi la mode ou le parti pris parisien favorable aux caractères romains avant qu’il ne développe ses nouvelles italiques aux majuscules penchées, dont le premier apparaît à Paris en 1543, avec quelques lignes chez De Tournes la même année. Ses quatre italiques des années 1540 feront sa réputation en France et ailleurs, mais sans éclipser ses caractères romains.
Définir, diviser et énumérer : l’exemple des anatomies de la Renaissance
Authors: Montagne Véronique 
Published: June 2021

Les dialectiques médicales de la Renaissance consacrent une part importante de leur développement à la question de la définition. Considérée comme un socle indispensable, un préalable dont l’importance est souvent mise en évidence, la définition est ainsi théorisée par Adrien L’Alemant, dans sa Dialectique en françois pour les barbiers et les chirurgiens (1553) comme par Philippe de Flesselles dans son Introductoire de chirurgie rationele (1547), eux-mêmes inspirés en cela par les travaux de Galien comme par ceux du maître de médecine Guy de Chauliac. L’approche définitionnelle fait partie du bagage du chirurgien « rationnel », quelle qu’en soit la forme exacte, formes qui sont explorées ici dans un corpus croisé de textes logiques, dialectiques et éventuellement rhétoriques, et d’anatomies de Charles Estienne, Ambroise Paré et Jacques Grévin, parues entre 1549 et 1569.

A Comparative Study to Evaluate the Efficacy and Cost of Rituximab versus Dexamethasone Cyclophosphamide Pulse in Patients of Pemphigus Vulgaris
Authors: Das Sudip , Agarwal Komal , Singh Sonal , Halder Deepika , Sinha Sujata , De Abhishek 
Published: June 2021

Introduction:
Rituximab is slowly getting recognized as a promising steroid-sparing agent in the treatment of moderate to severe cases of pemphigus vulgaris (PV). We evaluated and compared the effectiveness, safety, and cost of therapy of rituximab versus dexamethasone cyclophosphamide pulse (DCP) in Indian patients with PV.

Materials and Methods:
It is a retrospective data analysis, from the Immunobullous disease clinic in a tertiary centre of eastern India, of management of PV. In our institute we use either rituximab or DCP for the management of moderate to severe cases of PV, depending on that we retrospectively divided the treated cases of PV in two groups. Patients who were treated with rheumatoid arthritis (RA) protocol of rituximab were considered to be group 1. Patients who were treated with DCP were included in group 2. Response was assessed by pemphigus area, and activity score (PAAS), Dermatology life quality index (DLQI); photographic documentation, and blood parameters were monitored.

Results:
Both groups showed significant improvement in PAAS and DLQI, the improvement was faster and well sustained in the rituximab group. In terms of safety and development of new vesicles, rituximab had a better profile with only 1 patient having adverse effects and none with new vesicles as compared to DCP (3 had adverse effects and 2 developed new vesicles).

Conclusions:
Rituximab offers the advantage of early and prolonged remission, lesser adverse effects, better effectiveness, less risk of relapses, faster improvement of PAAS, and DLQI. Though rituximab is an expensive drug, but on evaluating the cost of whole therapy, it was seen that rituximab infusions are actually cheaper compared to DCP pulse. We suggest, rituximab can be used as the first-line of therapy for pemphigus vulgaris in the Indian context.
Skin Damage Induced by Enhanced Protective Measures in Frontline Doctors During Covid-19 Pandemic
Authors: Saha Mahimanjan , Podder Indrashis , Das Anupam 
Published: June 2021

Background:
Frontline doctors engaged in COVID-19 duties have to adopt enhanced protective measures to minimize their risk of exposure. However, these measures may lead to several skin problems, thereby affecting their performance.

Objectives:
To analyze skin changes induced by enhanced protective measures and explore possible risk factors.

Materials and Methods:
A web-based descriptive study was conducted among 212 frontline COVID-19 doctors. Data were collected regarding their demography, duty, use of enhanced protective measures including prophylactic hydroxychloroquine, recent skin changes with affected sites, and possible risk factors.

Results:
Skin changes were reported by 41.5% of respondents (mean age 34.8 ± 5.6 years) across 210 sites. Hands were involved most commonly in 77.3% of doctors, followed by nasal bridge, cheeks, and retroauricular area. Dryness (84.1%) and skin peeling (79.5%) were the commonest clinical features. Regression model showed prolonged PPE wear (>6 h) adjusted odd's ratio (AOR) 2.9, P = 0.005], heavy sweating [AOR 12.8, P = 0.001] and frequent hand hygiene (>10 times/day) [AOR 3.1, P = 0.0006] to be significant risk factors. Hydroxychloroquine prophylaxis was deemed safe as treatment-emergent adverse events were uncommon (17.4%).

Conclusion:
Frontline doctors have an increased risk of developing skin damage due to enhanced protective measures. Appropriate steps should be taken to address the risk factors and minimize skin damage. Persistent cases mandate dermatology referral for optimum management.
A Randomized Comparative Study of MIP and MMR Vaccine for the Treatment of Cutaneous Warts
Authors: Kaur Amandeep , Brar Balvinder Kaur , Kumar Sumir , Brar Sukhmani Kaur , Boparai Amarbir Singh , Puri Neerja 
Published: June 2021

Objectives:
To evaluate and compare the efficacy of MMR vaccine and MIP vaccine for resolution of Cutaneous warts (Cw).

Methods:
The hospital-based prospective randomized interventional study was done where a total of 60 patients of Cw were divided into two groups of 30 patients each: Group A received 0.1 ml of intralesional injection of MIP vaccine and Group B received 0.5 ml of MMR vaccine. The treatment protocol involved three intralesional injection of vaccines at intervals of 3 weeks (maximum of three injections). The follow-up was done every 4 weeks for at least 24 weeks for the comparison of the two groups. The primary outcomes were the decrease in size of the wart or clearance of primary warts. The secondary outcomes were the improvement in the distant warts and any complications related to the use of vaccines. The data were entered in MS Excel and analyzed using SPSS 17.0 version. A P value of <0.05 was considered statistically significant.

Results:
The baseline demographic and wart characteristics were comparable between the two groups (P > 0.05). As compared to MMR, MIP showed an early (9.41 vs 11.71 weeks, P = 0.027), and a significantly higher complete response (90% vs 76.67%) with P < 0.05. The less duration of the warts was significantly associated with the higher complete response (P < 0.05) in both the groups. The common side effects were erythema/inflammation [19 (63.34%)] in Group A and pain during the injection [19 (63.34%)] in Group B with P < 0.0001.

Conclusion:
In conclusion, MIP intralesional injections have a quicker response and are more efficacious compared to MMR in the treatment of Cw, though each vaccine carries its own sets of side effects.
Measuring Cervical Range of Motion with Gyroscope/Accelerometer Eyeglasses (JINS MEME) in Persons with and without Neck Pain
Authors: Kimio Saitoh , Rosario Karina Del , Masato Nagao , Pascual Lisa , Morshed Saam , Naohisa Miyakoshi , Yoichi Shimada 
Published: June 2021

Context:
Neck pain is common in the general population. Active cervical spine range of motion (ACROM) is often measured in the diagnosis, evaluation, and treatment of neck pain. However, commonly used measurement tools have been deemed inaccurate or impractical. The Cervical Range of Motion (CROM) Instrument, which uses inclinometers and a magnetic reference, has demonstrated high reproducibility and validity in the measurement of ACROM, however, its practicable use is suboptimal due to its large dimensions. The JINS MEME eyeglass is a lightweight and compact wearable device that contains gyroscope and accelerometer electrodes capable of detecting body motion offering an alternative means of measuring ACROM.

Aims:
The primary aim of this study is to validate ACROM measurements using the JINS MEME eyeglasses in comparison to the CROM Instrument. The secondary aim is to investigate the variable range of motion patterns between individuals with neck pain (NP group) versus asymptomatic individuals (AS group).

Settings and Design:
This was a cross-sectional, clinical measurement, and reliability study.

Subjects and Methods:
Seven neck pain and 14 asymptomatic individuals underwent ACROM measurements with the JINS MEME and CROM Instrument concurrently.

Statistical Analysis Used:
Intraclass correlation coefficient was used to determine inter- and intra-rater reliability of the JINS MEME and CROM Instrument. Mann–Whitney's U-test was used to assess differences between the two groups (NP group vs. AS group) in ACROM.

Results:
Using the JINS MEME eyeglasses, we observed excellent intra- and inter-rater reliability for nearly all ACROM directions (cervical spine flexion, extension, and lateral bending) except for rotation which was considered poor. ACROM was decreased in all directions for neck pain patients when measured by both devices.

Conclusions:
The JINS MEME eyeglasses showed excellent intra- and inter-rater reliability for all ACROM movements except for cervical rotation. Comparing the AS group and NP group, the ACROM of the NP group was significantly decreased compared to that of the AS group in all cervical spine directions, similar to findings in previous studies. With the exception of the measurement of cervical rotation, the JINS MEME eyeglasses demonstrated similar accuracy to the CROM Instrument in the assessment of ACROM in both the NP and AS groups.
The space of twisted cubics
Authors: Heinrich Katharina , Skjelnes Roy , Stevens Jan 
Published: June 2021

We consider the Cohen-Macaulay compactification of the space of twisted cubics in projective n-space. This compactification is the fine moduli scheme representing the functor of CM-curves with Hilbert polynomial 3t+1. We show that the moduli scheme of CM-curves in projective 3-space is isomorphic to the twisted cubic component of the Hilbert scheme. We also describe the compactification for twisted cubics in n-space.Comment: 22 pages. Final version
