« Auto-affection et événement »
Authors: Walton Roberto J. 
Published: April 2021

Cette contribution témoigne de l’importance de la réception de la phénoménologie de langue française en Amérique Latine. En revisitant la thèse de la duplicité de l’apparaître – apparaître de la vie comme affect et comme force, apparaître du monde comme sens et distance –, Roberto J. Walton s’attache au concept fondamental de la phénoménologie de la vie, en mettant en avant des modalités dans lesquelles l’auto-affection opère sans hétéro-affection d’une manière avérée. Il précise d’emblée que cette auto-affection sans hétéro-affection est définie par deux aspects : un premier « aspect de base » – ou rapport de fondation – en vertu duquel l’auto-affection est la condition de possibilité de toute intentionnalité ou ek-stase ; et un deuxième aspect « d’intensification ou d’excédence » qui renvoie à la phénoménologie de l’événement, en ceci que l’auto-affection y apparaît dans une sorte de plus-value, c’est-à-dire dans la condition de l’acte comme accroissement créateur.
La critique de la déraison économique chez Michel Henry
Authors: Leclercq Jean 
Published: April 2021

Jean Leclercq livre une étude où il pointe d’abord quelques constats qui en appellent à la nécessité de penser philosophiquement l’argent. Il met ainsi en avant ce qu’il considère les « affres de la réduction mercantile », notamment celles qui nuisent à la valeur de nos liens sociaux, tout en montrant les problèmes philosophiques soulevés par une telle situation. Il aborde ensuite la spécificité et la pertinence du traitement que M. Henry réserve à cette question pour en tirer une conclusion effective, à savoir « penser politiquement l’argent ». Son étude se termine en soulevant des champs d’action, tels que la régulation des usages, la nécessité de penser l’argent dans son rapport à la citoyenneté, les dénonciations des logiques marchandes, la réflexion radicale et renouvelée sur les politiques fiscales, et la réflexion sur la nécessité de libérer des domaines de la vie sociétale de liens d’effectivité avec l’argent, en sorte de « sanctuariser l’inévaluable ».
L' essence de l’apparaître chez Henry et Patočka
Authors: Ortega Rodríguez Iván 
Published: April 2021

Iván Ortega Rodríguez livre une contribution où M. Henry est mis en confrontation avec Patočka, notamment sur la corrélation entre la vie et le monde, autrement dit sur l’« a priori de corrélation ». Comme le rappelle l’auteur de cette étude, tant Patočka que M. Henry adoptent cette corrélation a priori comme point de départ, et donc eu égard aux questions portant respectivement sur l’apparaître, sur ce qui apparaît et sur cette vie subjective qui semble devoir accompagner toute donation. Aussi Iván Ortega Rodríguez soutient-il que tout semble se jouer entre M. Henry et Patočka dans leur conception de l’apparaître. Autant la donation henryenne nous invite à nous singulariser dans notre expérience selon le pathos de la vie auto-affective, autant elle nous invite chez Patočka à sortir hors de nous-mêmes selon la priorité accordée à l’aspect de « champ » que nous trouvons dans le se-montrer, là où se place tout ce qui est donné.
Travail, mesure et temps
Authors: Touboul Hervé 
Published: April 2021

Apres avoir reconnu la justesse du geste henryen, consistant à placer l’individu vivant au centre de son interprétation, c’est l’atomisation voire l’approche « nominaliste » du travail qui en découle qu’Hervé Touboul met vigoureusement en question, au fil d’une analyse approfondie de la manière dont M. Henry en viendrait à méconnaitre les dialectiques, toujours à l’œuvre dans le texte de Marx, de la quantité et de la qualité, ou de la valeur d’usage et de la valeur d’échange. L’auteur pense décisif d’interroger la posture henryenne : la conception réductrice du travail – comme qualité pure et refus de l’objectivité, au nom de la subjectivité transcendantale. D’où la difficulté à aborder la socialité du travail – les médiations dont elle est tissée, son anonymat irréductible à toute inter-personnalité – et au-delà, à dégager les conditions de sa répétition proprement politique.
Complex geodesics in convex domains and ℂ-convexity of semitube domains
Authors: Zając Sylwester , Zapałowski Paweł 
Published: April 2021

Abstract
In this paper the complex geodesics of a convex domain in ℂ
n
are studied. One of the main results provides a certain necessary condition for a holomorphic map to be a complex geodesic for a convex domain in ℂ
n
. The established condition is of geometric nature and it allows to find a formula for every complex geodesic. The ℂ-convexity of semitube domains is also discussed.
Hyperbolic torsion polynomials of pretzel knots
Authors: Morifuji Takayuki , Tran Anh T. 
Published: April 2021

Abstract
In this paper, we explicitly calculate the highest degree term of the hyperbolic torsion polynomial of an infinite family of pretzel knots. This gives supporting evidence for a conjecture of Dunfield, Friedl and Jackson that the hyperbolic torsion polynomial determines the genus and fiberedness of a hyperbolic knot. The verification of the genus part of the conjecture for this family of knots also follows from the work of Agol and Dunfield [1] or Porti [19].

We devise two novel topological arguments to deal with general classes of potential wells.

Organic electrochemistry: Synthesis and functionalization of β-lactams in the twenty-first century
Authors: Bortolami Martina , Chiarotto Isabella , Mattiello Leonardo , Petrucci Rita , Rocco Daniele , Vetica Fabrizio , Feroci Marta 
Published: April 2021

Abstract
Organic electrochemistry is a technique that allows for the heterogeneous redox reactions avoiding both the use of stoichiometric amounts of redox reagents and the resulting formation of stoichiometric by-products. In fact, the redox reagent in these reactions is the electron, which is naturally eco-friendly and produces no side compounds. It is therefore quite obvious that electrochemistry can be classified as a “green” technology. The use of this methodology in the synthesis of β-lactams is not a novelty, but the growing interest in this class of biologically active compounds, due to the discovery of new fields of application (after a moment of decrease in interest due to antibiotic resistance) has been a stimulus for the search for more efficient electrochemical ways to synthesize and transform β-lactams. Thus, this review deals with the twenty-first-century applications of electroorganic technique to the chemistry of β-lactams, by analyzing first the syntheses classified by the type of reactions (cyclization, cycloaddition, etc.) and then by manipulating the β-lactam structure, using it as a synthon. Lastly, the importance of this technique is demonstrated by a study of a pilot plant scale reduction of a cephalosporanic acid derivative to a commercially important antibiotic.
New graph algorithms via polyhedral techniques
Authors: Tarnawski Jakub 
Published: April 2021

AbstractThis article gives a short overview of my dissertation, where new algorithms are given for two fundamental graph problems. We develop novel ways of using linear programming formulations, even exponential-sized ones, to extract structure from problem instances and to guide algorithms in making progress.The first part of the dissertation addresses a benchmark problem in combinatorial optimization: the asymmetric traveling salesman problem (ATSP). It consists in finding the shortest tour that visits all vertices of a given edge-weighted directed graph. Aρ-approximation algorithm for ATSP is one that runs in polynomial time and always produces a tour at mostρtimes longer than the shortest tour. Finding such an algorithm with constantρhad been a long-standing open problem. Here we give such an algorithm.The second part of the dissertation addresses the perfect matching problem. We have known since the 1980s that it has efficient parallel algorithms if the use of randomness is allowed. However, we do not know if randomness is necessary – that is, whether the matching problem is in the classNC. We show that it is in the classquasi-NC. That is, we give a deterministic parallel algorithm that runs in poly-logarithmic time on quasi-polynomially many processors.
An inverse problem of radiative potentials and initial temperatures in parabolic equations with dynamic boundary conditions
Authors: Ait Ben Hassi El Mustapha , Chorfi Salah-Eddine , Maniar Lahcen 
Published: April 2021

Abstract
We study an inverse problem involving the restoration of two radiative potentials, not necessarily smooth, simultaneously with initial temperatures in parabolic equations with dynamic boundary conditions. We prove a Lipschitz stability estimate for the relevant potentials using a recent Carleman estimate, and a logarithmic stability result for the initial temperatures by a logarithmic convexity method, based on observations in an arbitrary subdomain.
Ernst Cassirer’s Legacy: History of Philosophy and History of Science
Authors: Ferrari Massimo 
Published: April 2021

AbstractThe paper is devoted to an overview of Cassirer’s work both as historian of philosophy and historian of science. Indeed, the “intelletcual cooperation” between history of philosophy and history of science represents an essential feature of Cassirer’s style of philosophizing: while the roots of a wide exploration stretching from Renaissance thought to modern physics go back to the Neo-Kantianism of the Marburg School, the results of a similar cross-fertilization of research fields have deeply contributed to shaping new standards of inquiry. Cassirer’s relationship with the Warburg milieu in Hamburg and late in his life with the American intellectual scenario (for instance, with the “Journal of History of Ideas”) are surely worthy of closer investigation. Distinguished scholars such as Meyerson, Brunschvicg, Burtt, Koyré, Metzger, Lovejoy, Kristeller, have disussed, appreciated, critizised Cassirer’s still today fascinating studies devoted to Pico della Mirandola, Galileo, Newton, Leibniz, to mention but a few. To explore some of these aspects focusing both on affinities and differences within a cosmpolitian intellectual community can provide a better understanding of philosophy and history of science in the first half of 20th century. Cassirer’s legacy requires, therefore, a new assessment.
Long-term stress level in a small mammal species undergoing range expansion
Authors: André Adrien , Michaux Johan , Gaitan Jorge , Millien Virginie 
Published: April 2021

Abstract
Rapid climate change is currently altering species distribution ranges. Evaluating the long-term stress level in wild species undergoing range expansion may help better understanding how species cope with the changing environment. Here, we focused on the white-footed mouse (Peromyscus leucopus), a widespread small mammal species in North-America whose distribution range is rapidly shifting northward. We evaluated long-term stress level in several populations of P. leucopus in Quebec (Canada), from the northern edge of the species distribution to more core populations in Southern Quebec. We first tested the hypothesis that populations at the range margin are under higher stress than more established populations in the southern region of our study area. We then compared four measures of long-term stress level to evaluate the congruence between these commonly used methods. We did not detect any significant geographical trend in stress level across our study populations of P. leucopus. Most notably, we found no clear congruence between the four measures of stress level we used, and conclude that these four commonly used methods are not equivalent, thereby not comparable across studies.
Cooperative optical wavefront engineering with atomic arrays
Authors: Ballantine Kyle E. , Ruostekoski Janne 
Published: April 2021

AbstractNatural materials typically interact weakly with the magnetic component of light which greatly limits their applications. This has led to the development of artificial metamaterials and metasurfaces. However, natural atoms, where only electric dipole transitions are relevant at optical frequencies, can cooperatively respond to light to form collective excitations with strong magnetic, as well as electric, interactions together with corresponding electric and magnetic mirror reflection properties. By combining the electric and magnetic collective degrees of freedom, we show that ultrathin planar arrays of atoms can be utilized as atomic lenses to focus light to subwavelength spots at the diffraction limit, to steer light at different angles allowing for optical sorting, and as converters between different angular momentum states. The method is based on coherently superposing induced electric and magnetic dipoles to engineer a quantum nanophotonic Huygens’ surface of atoms, giving full 2π phase control over the transmission, with close to zero reflection.
A simplified kinetic model for modern cooking of aspen chips
Authors: Gilbert Wesley , Allison Bruce , Radiotis Theodore , Dort Arnold 
Published: April 2021

Abstract
Kraft pulping kinetic models are an important component of any fundamental continuity based continuous digester model. These models can be used to further develop our understanding, or as a framework to support the development of real-world control, estimation and optimization strategies. Effective models are tailored to a specific species of wood and must be applicable for a wide range of expected cooking conditions. In this work a series of experiments were conducted on hardwood Aspen chips for 5 different cooking conditions. Each series of cooks were interrupted at different time intervals to capture the dynamic response of the cook. The key chips and liquor components were measured and reconciled at each interval.
A dynamic model was then developed based on a simplification of a continuous digester model under batch conditions. This ensures continuity between the key assumptions governing both the batch kinetics model and the expanded continuous form. A kinetic model structure was adapted from the literature that quantifies all three accepted phases of lignin and cellulose degradation, i. e. the initial, bulk and residual phases as well as the effect of modern cooking practices such as intra-cook white liquor addition on the transition between the bulk and residual phases. Additionally, modifications were made to the kinetic model structure to reduce the overall number of states and to impose a floor limit on degradation, thereby reducing the overall complexity and computational burden. The model was then fit to the data using weighted least squares and simulation optimization techniques.
A Diachronic Maltese Islandscape: Rural Ta’ Qali and ix-Xarolla
Authors: Vella Clive , Spiteri Mevrick 
Published: April 2021

AbstractThe archaeological study of the Maltese Islands has received considerable scholarly attention in regard to its island settings and long-term human occupation. However, emphasis on the prehistoric periods of the archipelago runs the risk of creating a biased focus with limited engagement in successive periods. In the spirit of this edited volume, the present article seeks to provide a broader chronological view of two rural areas in the larger island of Malta: Ta’ Qali and ix-Xarolla. These two areas have offered some evidence, through intermittent discoveries from recent construction activities, of three broad periods of increased landscape manipulation and transformation during the Middle-Late Bronze Age, Roman, and Early Modern periods. In seeking to provide an islandscape-based narrative, this article seeks to show that the Maltese Islands experienced periods of more intense human occupation that would have inevitably impacted the agriculturally viable areas of Ta’ Qali and ix-Xarolla. Therefore, despite the Roman period focus of this edited volume, this article takes a long-term view of two rural areas to illustrate identifiable landscape uses and changes.
Ecclesial Belonging in a World of Pure Experience: William James, W. E. B. Du Bois, and Religious Rationality in Crisis
Authors: Stepanenko Walter Scott 
Published: April 2021

Abstract
The global COVID-19 pandemic has spotlighted several instances of churches violating state issued and scientifically recommended guidelines designed to keep populations healthy and to prevent the further spread of the disease. While these instances are minority responses to these orders, they nonetheless raise questions about the rationality of ecclesial belonging in response to the COVID-19 pandemic. In this article, I draw on the work of William James and W. E. B. Du Bois to articulate a conception of ecclesial belonging as a social epistemological process engaging a complex, fluid multiplicity of knowers of various scales. I argue that, in this view, ecclesial rationality involves the construction of a concatenation of internal and external practices individual believers and groups can traverse so long as they consistently satisfy a plurality of desiderata. I suggest that what is irrational about religious-based defiance of COVID-19 guidelines is the church-sanctioned severance of internal from external practices. I suggest that this behavior is supported by a failure to grasp the demands of ecclesial rationality rather than embrace them, and that this conception of rationality may have been eroded by the value-neutral skepticism of secular rationality.
Voice onset time and constriction duration in Warlpiri stops (Australia)
Authors: Bundgaard-Nielsen Rikke L. , O’Shannessy Carmel 
Published: April 2021

AbstractThis paper presents a first detailed analysis of the Voice Onset Time (VOT) and Constriction Duration (CD) of stops /p t ʈ c k/ and flap /ɽ/ in the Indigenous Australian language Warlpiri as spoken in Lajamanu Community, in Australia’s Northern Territory. The results show that Warlpiri stops are realised as voiceless, long-lag stops word-initially, as well as word-medially, where /p t k/ are also characterised by CDs in excess of 100 ms. This is similar to what has been reported for Kriol, and for the emerging mixed language Light Warlpiri, also spoken in the community, and by some of the participants. The results indicate that Warlpiri does not obligatorily make a word-medial distinction between stops orthographically represented by ‘rt’ and ‘rd’, which have previously been argued to be realised as /ʈ/ and /ɽ/, respectively, at least in some varieties of Warlpiri. Finally, the results also suggest that the realisation of word-initial Warlpiri flap /ɽ/ is highly variable, potentially resulting in a near-merger with /ɻ/.
Dissolving pulp production: Cellulases and xylanases for the enhancement of cellulose accessibility and reactivity
Authors: Kumar Amit 
Published: April 2021

AbstractDissolving pulps are high-grade cellulose pulps that have minimum amount of non-cellulosic impurities. Dissolving pulps are the basic source for the manufacturing of several cellulosic products such as viscose, lyocell, cellulose acetates, cellulose nitrates, carboxymethyl-cellulose, etc. Dissolving pulps are mainly manufactured by pre-hydrolysis kraft and acid sulphite pulping. A high reactivity of dissolving pulps is desirable for its eco-friendly utilization for several purposes. Several approaches including mechanical, chemical, ultrasonic, and enzymatic treatments have been employed for the improvement of pulp reactivity. This review mainly focussed on pulp reactivity improvement through enzymatic approaches. Cellulases and xylanase have been proved effective for the improvement of pulp reactivity of dissolving pulp from different sources. The different combinations of cellulase, xylanase, and mechanical refining have been tested and found more effective rather than the single one.

Published: April 2021

Abstract

Objectives
There is no reliable and valid biomarker to identify Irritable bowel syndrome (IBS) and its subtypes. The aim of this study is to explore potential serum biomarkers that may be associated with IBS subtypes, particularly in the vitamin D pathway.

Methods
The study population comprised 75 IBS patients and 79 controls. Patients divided into IBS subtypes. Routine biochemical parameters, 25-OH-vitamin D, vitamin D binding protein (VDBP) and vitamin D receptor (VDR) serum levels were compared between IBS subtypes and controls. Factors related to IBS subtypes were examined by multivariate logistic regression analysis.

Results
Vitamin D levels were lower; VDBP and VDR were higher in all IBS patients than in controls (p<0.001; 0.047 and 0.029, respectively). According to logistic regression analysis, VDBP was a disease-related parameter as much as vitamin D in all IBS subtypes. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were higher especially in diarrhea-dominant IBS (IBS-D) (p=0.041; 0.046) and vitamin B12 were significantly lower in constipation-dominant IBS (IBS-C) (p=0.001).

Conclusions
Increased VDBP levels were associated with all IBS subtypes. Patients, especially in IBS-D, had higher serum levels of VDBP, CRP and ESR. Vitamin B12 deficiency, which we consider as a result of the disease, was more common in IBS-C.
