Abstract:

Komputer membutuhkan kecerdasan buatan/artificial intelligence agar dapat bermain selayaknya manusia pada Connect Four/Connect4. Terdapat beberapa algoritma yang dapat diterapkan pada Connect4, namun tidak diketahui mana yang cocok. Algoritma yang cocok berarti optimal dalam memilih langkah sekaligus waktu eksekusinya tidak lambat pada kedalaman pencarian/depth yang cukup dalam. Pada penelitian ini, akan dilakukan analisis dan perbandingan antara alpha beta (AB) Pruning dan MTD(f) pada prototipe Connect4, dalam hal keoptimalan (persentase kemenangan) dan kecepatan (waktu eksekusi dan jumlah simpul daun). Pengujian dilakukan dengan menjalankan mode komputer melawan komputer dengan kondisi berbeda. Persentase yang diraih MTD(f) berdasarkan pengujian adalah menang 41,67%, kalah 41,67% dan seri 16,66%. Pada pengujian dengan depth 8, waktu eksekusi MTD(f) 35,19% lebih cepat dan mengevaluasi simpul daun 66,2% lebih sedikit dibandingkan AB Pruning. Hasil dari penelitian ini adalah MTD(f) sama optimalnya dengan AB Pruning pada prototipe Connect4, namun MTD(f) secara rata-rata lebih cepat dan mengevaluasi simpul daun lebih sedikit dibandingkan AB Pruning. Waktu eksekusi MTD(f) tidak lambat dan jauh lebih cepat dibandingkan AB Pruning pada depth yang cukup dalam.

Abstract:

AbstractTo understand the origin of protein/nucleic acid based life as we know it on Earth, we must “follow” the nitrogen. Because of its unique hydrogen bonding characteristics, nitrogen is the key element in catalytic and/or informational proteins and nucleic acids essential to cell function and reproduction. We present evidence that HCN is the original source of prebiotic protein and nucleobase nitrogen. We also present chemically rational models supporting the radical hypothesis that the polymerization of HCN yields ab initio mundi prebiotic protein and polynucleobase macromolecules of sufficient size and complexity to allow the spontaneous generation of pre-RNA World biopolymers capable of catalysis and information transfer.

Abstract:

The asymmetric unit of the title thiazole derivative containing a sulfonylhydrazinic moiety, C9H8ClN3O3S2·H2O, consists of two independent molecules and two water molecules. The central parts of the molecules are twisted as both the molecules are bent at both the S and N atoms. In the crystal, N—H...N, N—H...O, C—H...O and O—H...O hydrogen-bonding interactions connect the molecules, forming layers parallel to the ab plane. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from O...H/H...O (32.9%) and H...H (22.6%) interactions.

Abstract:

Let A be a finite commutative ring with unity (ring for short). Define a mapping ? : A2 ? A2 by (a, b) 7? (a + b, ab). One can interpret this mapping as a finite directed graph (digraph) G = G(A) with vertices A2 and arrows defined by ?. The main idea is to connect ring properties of A to graph properties of G. Particularly interesting are rings A = Z/nZ. Their graphs should reflect number-theoretic properties of integers. The first few graphs Gn = G(Z/nZ) are drawn and their numerical parameters calculated. From this list, some interesting properties concerning degrees of vertices and presence of loops are noticed and proved.

Abstract:

MP2/6–311++G(d,p) calculations on C6H6···(HF)n clusters were performed and full optimizations were carried out for systems containing up to four HF molecules (n = 4) and calculations on the systems of C6v symmetry were carried out for up to six HF molecules (n = 6). Cooperativity effects were analyzed for these molecular aggregates. It was found that F–H···π and F–H···F hydrogen bonds exist for these complexes and those interactions are enhanced as the number of HF molecules increases. The cooperativity effects cause numerous changes in geometrical, energetic, and topological parameters, the latter ones derived from the quantum theory of atoms in molecules. Various correlations between the analyzed parameters are presented. There are meaningful differences between the molecular graphs for the fully optimized complexes and those for the linear complexes of C6v symmetry (for the latter, the linear chain of HF molecules is attached to a benzene molecule acting as the Lewis base). For the linear complexes, unique bond paths connect the H-attractor of the HF molecule and the ring critical point of the benzene molecule.

Abstract:

The title lanthanide complex, [Er2(C6H2O4)3(H2O)6]·18H2O, is isostructural with its La, Gd, Yb and Lu analogues. The Er3+ ion, located on a threefold rotation axis, is nine-coordinated in a distorted tricapped trigonal–prismatic geometry, which is completed by six oxygen atoms from three dhbq2− ligands and three oxygen atoms from coordinated water molecules. Each dhbq2− ligand acts in a μ2-bis(bidentate) bridging mode to connect two Er3+ ions to form honeycomb (6,3) two-dimensional sheets extending in the ab plane, having an Er...Er separation of 8.7261 (2) Å. In the crystal, extensive O—H...O hydrogen-bonding interactions involving the coordinated water molecules and the water molecules of crystallization, as well as the oxygen atoms of the dhbq2− ligands, generate an overall three-dimensional supramolecular network.

Abstract:

Im Kontext steigender Versorgungsbedarfe, eines grassierenden Fachkräftemangels und einer Krise sozialer Reproduktion kommt es seit den 1990er Jahren zu einem sozial- und pflegepolitischen Ausbau niedrigschwelliger und informeller Pflegearbeit in den Grauzonen des Pflegemarktes in Deutschland. Angetrieben durch einen spezifischen Kostendruck, entsteht mithilfe politischer Förderstrategien ein Regime gemeinwohldienlicher Schattenarbeit, das für das Berufsfeld der Pflege typische Informalisierungsprozesse in neuer Gestalt und unter gewandelten Reproduktionsbedingungen fortführt und vorantreibt. Exemplarisch dafür ist einerseits der politisch regulierte Einsatz sogenannter „zusätzlicher Betreuungskräfte“ sowie andererseits die staatliche Förderung freiwilligen Engagements in der Pflege. Im Rahmen dieses Ausbaus geringqualifizierter Beschäftigungssegmente, niedrigschwelliger Betreuungsangebote und quasi-professionalisierter Tätigkeitsbereiche sind Informalisierungsprozesse und Fälle rechtswidriger Arbeitskraftnutzung, qualifikatorische Grenzüberschreitungen und Unterschichtungsprozesse zu beobachten. Diese Entwicklungen werden vom Berufsprofil der Pflege als einer hochgradig feminisierten und „unvollständigen Profession“ begünstigt. Der Beitrag zielt mit der Vorstellung ausgewählter Befunde einer qualitativen Interviewstudie zum Einsatz zusätzlicher Betreuungskräfte und freiwillig Engagierter im Kontext des gegenwärtigen Pflegenotstands darauf ab, die Bedeutung sozialpolitischer Maßnahmen für Informalisierungsprozesse im Sorgearbeitskontext „entwickelter Gesellschaften“ empirisch fundiert zu exemplifizieren.

Abstract:

Abstract Background An estimated 65,000 New Mexicans are infected with HCV, accounting for ~3% of the state’s population with intravenous drug use being the most common risk factor for the acquisition of HCV. In 2020, the US Preventive Service Task Force recommended universal HCV screening for all adults aged 18 to 79 years old. HCV screening requires a two-step process involving a HCV antibody (Ab) test followed by a confirmatory HCV ribonucleic acid (RNA) test to detect active infection. Acute HCV infections are typically asymptomatic leaving many individuals unaware of their diagnosis for years. New Mexico was one of the first states to abandon the requirement for specialist referral, fibrosis staging, and abstinence from substance abuse to facilitate HCV treatment. Despite removal of these barriers, major gaps in access to HCV treatment still persist. The objective was to develop a HCV connect-to-care cascade for the University of New Mexico Hospital (UNMH) to understand the potential barriers preventing patients from receiving appropriate care. Methods This was a retrospective, single center, descriptive study conducted at UNMH, a level 1 trauma, tertiary care academic medical center with 527 beds. All patients with a positive HCV Ab, RNA, or genotype obtained in 2018 were included in this study. There were no exclusions. Results In 2018, over 11,000 unique patients received HCV testing in any form resulting in a total of 14,566 HCV tests being performed. 2018 UNMH Connect-to-Care Cascade Conclusion Of the patients who screened positive, only 61.7% were referred for treatment, representing the largest gap in the cascade. However, once patients were seen in the clinic, 88.5% completed treatment with 100% having sustained virologic response (SVR). With the pan-genotypic HCV treatments having fewer side effects and high clinical success rates, it’s feasible that HCV treatment may no longer require a specialist. Similar to the rapid initiation of antiretrovirals in newly diagnosed HIV patients, where immediate access to treatment within days of diagnosis resulted in improved retention in care, decreased time to viral suppression, and decreased viral transmission, rapid initiation of HCV treatment may be the wave of the future.

Abstract:

Whereas McGovern calls for a moratorium on the ever increasing (ab)use of the word ‘contradiction’, principally because scholars of work and employment fail to connect different levels of analysis and/or demonstrate how and why contradiction(s) lead to widespread instability and upheaval, it can be demonstrated how both can be achieved through the ‘system, society, dominance’ framework. In what follows, the empirical focus is on the safety-critical work of airport ground service providers (GSPs), where key elements of the employment relationship embody contradictions that can be traced to the (sub-)system (mode of production) of a Single European Aviation Market (SEAM) that is now dominated by low fares airlines (LFAs). Instead of a moratorium, scholars of work and employment need to reconnect with society and theoretically ground their analysis in a (capitalist) system beset with contradictions between the forces and relations of production.

Abstract:

Ni7(C4H4O4)4(OH)6(H2O)3. 7H2O, a new layered nickel(II) succinate, was prepared hydrothermally (180°C, 48 h, autogenous pressure) from a 1:1.5:4.1:120 mixture of nickel (II) chloride hexahydrate, succinic acid, potassium hydroxide and water. It crystallizes in the monoclinic system (space group P21/c, Z = 4) with the following parameters a = 7.8597(1) Å, b = 18.8154(3)Å, c = 23.4377(4) Å,ϐ = 92.0288(9)°, and V = 3463.9(2) Å3. Its structure, which contains 55 non-hydrogen atoms, was solved ab initio from synchrotron powder diffraction data. It can be described from hybrid organic-inorganic layers, constructed from nickel oxide corrugated chains. These chains are built up from NiO6hexameric units connected via a seventh octahedron. Half of the succinates decorate the chains, and the others connect them to form the layers. The three dimensional arrangement is ensured by hydrogen bonds directly between two adjacent layers and via free water molecules.

Abstract:

The r-centroid concept, was proposed the in 1950s to permit factoring of the band strength integral Sυ',υ'' into the product of the FranckCondon factor qυ',υ'', and of the square of the electronic transition moment Re (r), when taken at the r-centroid value of the internuclear separation, r = [Formula: see text]υ',υ'', which is the most likely value r at which the υ' « υ'' transition will occur. It has been much used since then in the interpretation of intensity measurements on many band systems of importance in astrophysics, atmospheric physics, space physics, and chemical physics to determine the variation of the electronic transition moment with internuclear separation, and thereby to derive band strengths, and other molecular transition probability parameters. It has been somewhat less used in recent years in the study of individual band systems, since the development of powerful computing facilities now allow for exact ab initio numerical studies to be made of individual molecules and their radiative transitions. Nevertheless the r-centroid concept, and some of its recent developments, provide much insight into the general systematics of diatomic molecular band systems and their spectra. This partly tutorial paper reviews the origins, properties, applications, and recent developments of the r-centroid concept. PACS No.: 33.70

Abstract:

The structures of three ammonium hydrogen alkyl phosphates, NH4PO2(OH)(OR) [R = Me (1), Et (2), Pr i (3)], have been solved ab initio from X-ray powder diffraction data. The structure determinations were based on Patterson search methods combined with difference-Fourier techniques and the refinement was carried out using Rietveld methods. Powder diffraction data were first collected for all three compounds in the reflection mode using Cu K α1+α2 radiation. A pronounced preferred orientation effect was found for all the samples, even by side-loading into a flat sample holder. A random orientation of the powder particles was obtained for (1) using a special suspension chamber for the sample preparation, while for (2) and (3) data were remeasured in capillaries using the transmission mode. Crystals of the ammonium hydrogen methyl phosphate (1) and the ammonium hydrogen ethyl phosphate (2) both belong to the monoclinic space group P21/c, Z = 4, with a = 9.9645 (4), b = 7.1801 (3), c = 7.8897 (3) Å and β = 96.243 (3)° for (1), and a = 12.6453 (4), b = 7.1502 (2), c = 7.9738 (2) Å and β = 108.875 (2)° for (2). The ammonium hydrogen isopropyl phosphate (3) crystallizes in space group An, Z = 4, with a = 6.2475 (2), b = 29.3825 (6), c = 4.6305 (1) Å and β = 100.904 (2)°. All three compounds are characterized by an extended hydrogen-bonding network involving the hydrogen phosphate units and the ammonium ions, forming double layers. The methyl (1), ethyl (2) and isopropyl groups (3), which point into the interlayer space, connect the layers by van der Waals interactions.

Abstract:

Summary This article tries to reconstruct the concept of temperament (complexia) and its links to the theory of four humours in Polish and European Renaissance writings (e.g., both Andrzej Glaber, Szymon of Łowicz, Wojciech Oczko and Johannes ab Indagine). The analysis covers the alleged influence of four liquids (black bile, yellow bile, phlegm, and blood) on a person’s body, the empirical methods of identifying one’s temperament, and the Renaissance typology of temperaments (including such categories as ‘good’, ‘bad’, or ‘strong’ humours) and their interpenetration. The article also examines the close relationship between the theory of humours and astrology. Renaissance scholars believed that movements and relative positions of celestial bodies were a key factor in determining any given temperament.

Abstract:

The intrusive effects of the WTO on Members regulatory freedom have been a growing concern since the establishment of the WTO Dispute Settlement System (DSS). An assessment of the WTO case law exposes that the Appellate Body (AB) has introduced some elements within the<br />necessity test under GATT (General Agreement on Tariffs and Trade) article XX which do not find support in the text of the agreement and are potentially invasive of countries regulatory autonomy. This paper examines the evolution of the WTO case law in relation to the necessity concept within GATT 1994. Finally, an adjustment in the application of the necessity test to make it more consistent with the GATT text and to achieve greater balance between free trade and WTO members’ regulatory autonomy is suggested.

Abstract:

Recent developments in mechanics of continua (the search for optimal shapes of bodies, homogenization theory, the study of the trabecular structure of bones, the dynamics of immiscible mixtures, etc.) render some of the introductory axioms of continuum mechanics inadequate. Not only does one need to give meaning to the join and meet of two bodies, but also to extend the consequent algebra so as to encompass the result of a countable sequence of operations of join or meet; and one should also be able to define the limit of a sequence of bodies. To achieve this goal we propose here to define a body ab initio through the assignment of a probability measure dπ. We realize that π leaves, generally, too much of the texture of the body unspecified; to make up for this deficiency, we suggest the use of appropriate texture measures, reminescent of Tartar's H-measures.9

Full text

Abstract:

The cosolvency models frequently used in solubility data modeling of drugs in mixed solvents were reviewed and their accuracies for calculating the solubility of solutes were briefly discussed. The models could be used either for correlation of the generated solubility data with temperature, solvent composition etc or for prediction of unmeasured solubility data using interpolation/extrapolation technique. Concerning the correlation results employing a given number of independent variables, the accuracies of the investigated models were comparable, since they could be converted to a single mathematical form, however, the accuracies were decreased when models emplyed more independent variables. The accurate correlative models could be employed for prediction purpose and/or screening the experimental solubility data to detect possible outliers. With regard to prediction results, the best predictions were made using the cosolvency models trained by a minimum number of experimental data points and an ab initio accurate prediction is not possible so far and further mathematical efforts are needed to provide such a tool. To connect this gap between available accurate correlative models with the ab initio predictive model, the generally trained models for calculating the solubility of various drugs in different binary mixtures, various drugs in a given binary solvent and also a given drug in various binary solvents at isothermal condition and/or different temperatures were reported. Available accuracy criteria used in the recent publications were reviewed including mean percentage deviation (MPD). The MPD for correlative models is 1-10% whereas the corresponding range for predictive models is 10-80% depend on the model capability and the number of independent variables employed by the model. This is an update for a review article published in this journal in 2008.

Full text

Abstract:

The concept of repair – and its very interesting synonyms (but, as we know, the synonyms are never perfectly superposing) – emphasises both its socially constructed meanings and its extra-theoretical relations or practical functions. My paper has two methodological goals. The first corresponds to the focus on the historical and social roots of the place of repair activities in different human societies, while the second consists in the insistence on the causes and consequences of the repudiation of repair in the present era of world capitalism. Passing over the etymological sources of the specific action of repair, we cannot neglect its interdependence with both the labour processes and the scarcity that characterised ab initio the human societies. The paper explains how rarity and social domination relations are ontological factors directly determining the activities of repair, and also how the indirect ontological factors of tool-making ability and the level of the means of production (or, more generally, of productive forces) and the structural relations intertwine and fuel these activities. The entire logic of epistemological origins but also of the historical attitudes towards repair reflects the role of the social domination, concretely, of the capitalist relations imposing only a fragmented, anti-ecological perspective on nature-society.

Abstract:

The concept of reticular chemistry is investigated to explore the applicability of the formation of Covalent Organic Frameworks (COFs) from their defined individual building blocks. Thus, we have designed, optimized and investigated a set of reported and hypothetical 2D COFs using Density Functional Theory (DFT) and the related Density Functional based tight-binding (DFTB) method. Linear, trigonal and hexagonal building blocks have been selected for designing hexagonal COF layers. High-symmetry AA and AB stackings are considered, as well as low-symmetry serrated and inclined stackings of the layers. The latter ones are only slightly modified compared to the high-symmetry forms, but show higher energetic stability. Experimental XRD patterns found in literature also support stackings with highest formation energies. All stacking forms vary in their interlayer separations and band gaps; however, their electronic densities of states (DOS) are similar and not significantly different from that of a monolayer. The band gaps are found to be in the range of 1.7–4.0 eV. COFs built of building blocks with a greater number of aromatic rings have smaller band gaps.

Abstract Context The CD40-CD154 co-stimulatory pathway plays an important role in the pathogenesis of Graves disease (GD) by promoting autoreactive B-cell activation. Objective Evaluate efficacy and safety of a human, blocking, nondepleting anti-CD40 monoclonal antibody, iscalimab, in hyperthyroid patients with GD. Design Open-label, phase II proof-of-concept study. Setting Multicenter. Patients Fifteen with GD. Intervention Patients received 5 doses of iscalimab at 10 mg/kg intravenously over 12 weeks. Main outcome measures Thyroid-related hormones and autoantibodies, plasma soluble CD40, free CD40 on B cells, soluble CXCL13, pharmacokinetics, and safety were assessed. Results The iscalimab intervention resulted in complete CD40 engagement for up to 20 weeks. A clinical response and biochemical euthyroidism was observed in 7 of 15 (47%) patients. Free and total triiodothyronine and thyroxine normalized in 7 patients who did not receive any rescue medication with antithyroid drugs (ATD), and 2/15 (13.3%) showed normal thyrotropin. Six (40%) patients required ATD. Four of 7 responders relapsed after treatment completion. Serum concentrations of thyrotropin receptor autoantibodies (TSH-R-Ab) significantly declined in all patients (mean 15.3 IU/L vs 4.0 IU/L, 66% reduction; P < 0.001) and TSH-R-Ab levels normalized in 4 (27%). Thyroperoxidase and thyroglobulin autoantibodies significantly decreased in responders. Iscalimab rapidly reduced serum CXCL13 concentrations (P < 0.001). Twelve (80.0%) patients reported at least 1 adverse event (AE). All treatment-related AE were mild or moderate and resolved by end of the study. Conclusion Iscalimab was generally safe and clinically effective in a subgroup of hyperthyroid GD patients. The potential therapeutic benefit of iscalimab should be further tested.

ZusammenfassungEine Zurechnung von Stimmrechten Dritter wird im Kapitalmarktrecht – zur Vermeidung von Umgehungen – in unterschiedlichen Regelungskomplexen angeordnet (vgl. § 34 WpHG, § 30 WpÜG). Von hervorgehobener Bedeutung ist dabei die Zurechnung unter dem Gesichtspunkt des sog. acting in concert gem. § 30 Abs. 2 WpÜG. Hiervon hängt in vielen Fällen maßgeblich ab, ob eine – zeit- und kostenintensive – Angebotspflicht der Konzertierenden nach § 35 Abs. 2 WpÜG begründet wird oder nicht. Besondere Schwierigkeiten bereitet die Konstellation „struktureller Dominanz“ innerhalb eines Abstimmungspools: Hier steht in Frage, ob sich die Stimmrechtszurechnung auch auf einen „einflusslos Konzertierenden“ erstrecken soll. Der vorliegende Beitrag zielt auf eine Problemlösung entlang einer näheren Analyse des Telos von § 30 Abs. 2 WpÜG. Darauf aufbauend wird für Konstellationen „struktureller Dominanz“ in Stimmrechtskoordinierungen ein neuer Ansatz entwickelt, der für den „Einflusslosen“ zwingend die Konzertierungsauflösung vorsieht, möchte dieser einer Angebotspflicht entgehen.

Abstract:

The topical workshop Strong QCD from Hadron Structure Experiments took place at Jefferson Lab from November 6–9, 2019. Impressive progress in relating hadron structure observables to the strong QCD mechanisms has been achieved from the ab initio QCD description of hadron structure in a diverse array of methods in order to expose emergent phenomena via quasi-particle formation. The wealth of experimental data and the advances in hadron structure theory make it possible to gain insight into strong interaction dynamics in the regime of large quark–gluon coupling (the strong QCD regime), which will address the most challenging problems of the Standard Model on the nature of the dominant part of hadron mass, quark–gluon confinement, and the emergence of the ground and excited state hadrons, as well as atomic nuclei, from QCD. This workshop aimed to develop plans and to facilitate the future synergistic efforts between experimentalists, phenomenologists, and theorists working on studies of hadron spectroscopy and structure with the goal to connect the properties of hadrons and atomic nuclei available from data to the strong QCD dynamics underlying their emergence from QCD. These results pave the way for a future breakthrough extension in the studies of QCD with an Electron–Ion Collider in the U.S.

Abstract:

The first lineage specification occurs during pre-implantation mammalian development. At the blastocyst stage, 2 cell lineages can be distinguished: the inner cell mass (ICM) and the trophectoderm (TE). The exact timing when embryo cells are skewed to these lineages is not clearly determined in mammalian species. In murine embryos, it has been suggested that the first cleavage plane might be related to the embryonic-abembryonic (Em-Ab) axis at blastocyst stage. Thus, the daughter cells of the 2-cell embryo might already be predisposed to a specific cell lineage further on development. The objective of the present study was to observe how the first cleavage in bovine embryos may be related to cell lineage allocation at the blastocyst stage, using a noninvasive tracing approach. Bovine oocytes were harvested, in vitro matured, and fertilised. At the 2-cell stage, embryos were injected in one blastomere with the membrane tracer DiI. At the blastocyst stage, embryos (n = 346) were classified as orthogonal when the Em-Ab axis was orthogonally divided by the borderline between labelled and non-labelled cells; as deviant if the borderline was overlapping the Em-Ab axis; and as random when the labelled and non-labelled cells were randomly distributed. Total cell count (TCC) and the ICM/TE ratio was allowed by DNA staining with 4′,6-diamidino-2-phenylindole (DAPI) and by immunostaining of the ICM with Sox2 antibody. Analysis of variance was performed by one-way ANOVA employing IBM SPSS v21 (SPSS Inc., Chicago, IL, USA) to determine any difference between the cell lineage allocation patterns, TCC, and the ICM/TE ratio. P-values = 0.05 were considered significant. All values are reported as mean ± standard error of mean. Within 40 repetitions, the blastocyst classification was as follows: orthogonal 14.9% (±2.32, n = 56), deviant 22.2% (±2.58, n = 80), and random 62.9% (±2.64, n = 210). A significant difference was found in the incidence between the random group against the orthogonal and deviant, but not between the latter two. Regarding TCC, a significant difference was observed only between the orthogonal (99.6 ± 11.7 cells, n = 15) and deviant (135 ± 7.3 cells, n = 25) groups, but not with random embryos (116 ± 5.5 cells, n = 42). Finally, no significant difference was found among the groups concerning the ICM/TE ratio (0.43 ± 0.07 for orthogonal, n = 7; 0.54 ± 0.06 for deviant, n = 14; and 0.40 ± 0.03 for random embryos, n = 26). In conclusion, bovine embryos present a marked tendency for a random distribution of the daughter cells derived from the 2-cell blastomeres. However, around 37% of the blastocysts present a patterned cell division, where the daughter cells remain together through pre-implantation development. The effect of these cell lineage allocation patterns on implantation and further embryo development needs to be addressed.The authors acknowledge Laboratoire d'Excellence Revive (Investissement d'Avenir, ANR-10-LABX-73) and CONACyT Mexico for funding.

Abstract:

The author examines the history of emergence of the controversial translation of “Eternal God” in the Slavic liturgical ceremony of the acceptance of Muslims into Orthodoxy; as well as reviews canonical texts and refers to the relevant scientific data to describe the known facts on the sources of the origin of this concept. Special attention is given to the problem of interpretation of the Islamic doctrine by John of Damascus, Theodore Abū Qurrah, Niketas Choniates, Bartholomew of Edessa, who had a remarkable impact upon the Byzantine perception of Islam. Leaning on the history of interpretation of the fundamental Quranic concept al-samad, the author provides a cross-section of the Orthodox – Muslim relations that have evolved over several centuries. The article demonstrates that the interpretation of the corresponding Quranic passage in the Christian polemical texts took the path of distortion and loose interpretation of the Islamic doctrine. The authentic Islamic description of al-samad along with the research dedicated to etymology of this word and its ancient pre-Islamic meaning are presented. The question is raised on the existence of various Slavic revisions of liturgical ceremony of acceptance of Muslims into Orthodoxy, since the initial centuries of the Christian mission on the Slavic lands until the amended versions of text emerged in the Russian Empire in the late XIX – early XX centuries, which expelled this term from circulation as improper.

Abstract:

The quantum-mechanically derived reaction coordinates (QMRC) for the proton transfer in (N—H—N)+ hydrogen bonds have been derived from ab initio calculations of potential-energy surfaces. A comparison is made between the QMRC and the corresponding bond-order reaction coordinates (BORC) derived by applying the Pauling bond-order concept together with the principle of conservation of bond order. We find virtually perfect agreement between the QMRC and the BORC for intermolecular (N—H—N)+ hydrogen bonds. In contrast, for intramolecular (N—H—N)+ hydrogen bonds, the donor and acceptor parts of the molecule impose strong constraints on the N—N distance and the QMRC does not follow the BORC relation in the whole range. The X-ray determined hydrogen positions are not located exactly at the theoretically calculated potential-energy minima, but instead at the point where the QMRC and the BORC coincide with each other. On the other hand, the optimized hydrogen positions, with other atoms in the cation fixed as in the crystal structure, are closer to these energy minima. Inclusion of the closest neighbours in the theoretical calculations has a rather small effect on the optimized hydrogen positions. [Part I: Olovsson (2006). Z. Phys. Chem. 220, 797–810.]

Abstract:

Zusammenfassung Einleitung Mit der Originalpublikation des Keystone Designed Perforator Flap Concepts (KDPFC) von Behan et al. im Jahre 2003 hat der Keystonelappen mit Fallserien bis zu 300 Lappenplastiken Einzug in die Familie der Perforatorlappen gehalten. Die Lappenplastik, welche an die Form eines römischen Torbogens angelehnt ist, basiert auf dem Vorhandensein von Perforansgefäßen. Eine subtile Präparation der einzelnen Perforatoren ist dabei aber nicht notwendig. Hinzu kommt die insgesamt simple und rasche operative Vorgehensweise. Der Anwendungsbereich umfasst, bis auf wenige topografische Ausnahmen, das gesamte Integument. Die Anzahl aufschlussreicher Publikationen zu Komplikationen, Nachteilen oder lokalen Einschränkungen sind jedoch, trotz des breiten Anwendungsspektrums, spärlich. Methode Anhand einer retrospektiven Analyse von 35 Patienten über einen Zeitraum von 36 Monaten wurde der Stellenwert des Lappenkonzeptes nach überwiegender Hauttumorresektion an der unteren Extremität evaluiert. Die Lappenauswahl orientierte sich an der Defektsituation unter Anwendung der im Original beschriebenen Lappenvarianten. Ergebnisse Insgesamt wurden 36 Lappenplastiken an 35 Patienten durchgeführt. Die Defektgröße betrug im Mittel 21 cm2 (von 2 cm2 bis 100 cm2). Wundheilungsstörungen wurden in 12 Fällen sowie Teil-/Totale Lappenverluste bei 4 Patienten beobachtet. Allerdings bedurfte nur 1 Patient mit Lappenverlust einer weiteren operativen Intervention. Alle anderen heilten unter entsprechender Wundbehandlung komplett ab. Patienten mit blutverdünnender Medikation hatten erstaunlicherweise weniger Komplikationen (4 von 10), als Patienten ohne entsprechende Antikoagulation. Hier waren es 12 von 25 Patienten. Auffällig war das Auftreten von Komplikationen inklusive der Lappenverluste (n = 3) bei 7 Patienten, die eine Defektdeckung am distalen sprunggelenknahen Unterschenkel sowie am Fuß benötigten. Diskussion Obwohl in einigen Fällen Wundheilungsstörungen auftraten, stellt das KDPFC insgesamt einen wertvollen Baustein in der rekonstruktiven Leiter dar. Das Lappenkonzept ist dabei in der Lage zahlreiche andere lokale und regionale Lappenplastiken, auch bei komplexeren Situationen, ohne Qualitätsverlust, zu ersetzen. Der distale Unterschenkel und der Fuß sind Bereiche, an denen das Konzept allerdings nur bedingt anwendbar ist. Komplexere Lappentechniken scheinen für diese Region aufgrund der höheren Flexibilität und des Aktionsradius geeigneter.

Abstract:

The structures of the four isomeric compounds of 6-methylquinoline with chloro- and nitro-substituted benzoic acids, C7H4ClNO4·C10H9N, namely, 2-chloro-4-nitrobenzoic acid–6-methylquinoline (1/1), (I), 2-chloro-5-nitrobenzoic acid–6-methylquinoline (1/1), (II), 3-chloro-2-nitrobenzoic acid–6-methylquinoline (1/1), (III), and 4-chloro-2-nitrobenzoic acid–6-methylquinoline (1/1), (IV), have been determined at 185–190 K. In each compound, the acid and base molecules are linked by a short hydrogen bond between a carboxyl O atom and an N atom of the base. The O...N distances are 2.5452 (12), 2.6569 (13), 2.5640 (17) and 2.514 (2) Å, respectively, for compounds (I)–(IV). In the hydrogen-bonded acid–base units of (I), (III) and (IV), the H atoms are each disordered over two positions with O site:N site occupancies of 0.65 (3):0.35 (3), 0.59 (4):0.41 (4) and 0.48 (5):0.52 (5), respectively, for (I), (III) and (IV). The H atom in the hydrogen-bonded unit of (II) is located at the O-atom site. In all of the crystals of (I)–(IV), π–π interactions between the quinoline ring system and the benzene ring of the acid molecule are observed. In addition, a π–π interaction between the benzene rings of adjacent acid molecules and a C—H...O hydrogen bond are observed in the crystal of (I), and C—H...O hydrogen bonds and O...Cl contacts occur in the crystals of (III) and (IV). These intermolecular interactions connect the acid and base molecules, forming a layer structure parallel to the bc plane in (I), a column along the a-axis direction in (II), a layer parallel to the ab plane in (III) and a three-dimensional network in (IV). Hirshfeld surfaces for the title compounds mapped over d norm and shape index were generated to visualize the weak intermolecular interactions.

Abstract:

We demonstrated a novel strategy for specific and persistent inhibition of antibody (Ab) production against blood group A or B carbohydrate determinants necessary for successful ABO-incompatible transplantation. Similar to human blood group O or B individuals, mice have naturally occurring Abs against human blood group A carbohydrates in their sera. B cells with receptors for A carbohydrates in mice belonging to the CD5+CD11b+B-1a subset have phenotypic properties similar to those of human B cells. These cells could be temporarily eliminated by injecting synthetic A carbohydrates (GalNAcα1–3, Fucα1–2Gal) conjugated to bovine serum albumin (A-BSA) and anti-BSA Abs. In mice that received the injection of A-BSA/anti-BSA Abs, the serum levels of anti-A IgM were reduced, but immunization with human A erythrocytes resulted in increased serum levels of anti-A Abs. When combined with cyclosporin A (CsA) treatment, which blocks B-1a cell differentiation, and treatment with A-BSA/anti-BSA Abs, the serum levels of anti-A Abs were persistently undetectable in the mice even after the immunization. B cells with receptors for A carbohydrates were markedly reduced in these mice. These results are consistent with the hypotheses that treatment with A-BSA/anti-BSA Abs temporarily depletes B cells responding to A determinants, and CsA treatment prevents the replenishment of these cells.

Abstract:

Background: Fatigue and its negative impact on life participation are top research priorities of people on chronic dialysis therapy. Energy management education (EME) is a fatigue management approach that teaches people to use practical strategies (eg, prioritizing, using efficient body postures, organizing home environments) to manage their energy expenditure during everyday life. Objective: The aim of this study is to explore whether EME is associated with improvements in fatigue and life participation in adults on chronic dialysis. Design: Five single-case interrupted time-series AB studies, and follow-up qualitative interviews. Setting: The hemodialysis and peritoneal dialysis units at an academic hospital in Toronto, Canada. Patients: In total, 5 patients on chronic dialysis therapy were purposively selected to represent diversity in age, gender, and modality. Measurements: Brief questionnaires assessing fatigue and life participation were administered weekly during the baseline and intervention periods. Additional validated questionnaires (the Fatigue Impact Scale, 36-Item Short-Form Health Survey [SF-36] Vitality Scale, and Canadian Occupational Performance Measure) were also administered at baseline and post-intervention. Methods: All participants underwent “The PEP Program,” a personalized, web-supported EME program designed to meet the needs of people on dialysis. During the program, participants complete 2 brief web modules about energy management, and then use energy management principles and a problem-solving framework to work on 3 life participation goals during sessions with a trained program administrator. Data were analyzed using visual analysis and the Tau- U statistic for the weekly time-series data, and thematic analysis for the qualitative interviews. Results: Three of 5 participants displayed a consistently positive response to the Personal Energy Planning (PEP) program across multiple measures of fatigue and life participation. Tau- U effect size estimates ranged from small to moderate, according to the time-series data. All 5 participants expressed that the program had benefited them in qualitative follow-up interviews, with the most common reported benefit being that the program made day-to-day activities easier. The format of the program was also said to be feasible and convenient. Limitations: An exploratory, proof-of-concept study that used a small set of participants and lacked an active control comparison. Conclusions: The PEP program might have potential for improving fatigue-related outcomes in people on chronic dialysis. Larger, controlled studies of the program are warranted.

Abstract:

Background: Bridging the gap between different phenomena, mechanisms and levels of description, different design methods can converge in a unitary way of formulation. This protocol consolidates the analogy and parallelism in the description of any unit operation of separation, as is the particular case of sedimentation. This holistic framework is compatible and complementary with other methodologies handled at length, and tries to contribute to the integration of some imaginative and useful - but marginal, heuristic or rustic- procedures for the design of settlers and thickeners, within well founded and unified methodology. Objective: Classical models for hindered sedimentation allow solid flux in the direction of the gravity field to be formulated by analogy to changes obeying a potential, such as molecular transfer in the direction of the gradient and chemical transformation throughout the reaction coordinate. This article justifies the fundamentals of such a suggestive generalized analogy through the definition of the time of the sedimentation unit (TSU), the effective surface area of a sedimentation unit (ASU) and the number of sedimentation units (NSU), as elements of a sizing equation. Methods: This article also introduces the generalization of the model ab initio: Analogy is a well known and efficient tool, not only in the interpretation of events with academic or coaching purposes, but also in the generalized modelling, prospective, innovation, analysis and synthesis of technological processes. Chemical Engineering protocols for the basic dimensioning of Unit Operations driven by potentials (momentum, heat and mass transfer chemical reaction) are founded in macroscopic balances of mass and energy. Results: These balances, emphatically called “design equations”, result from the integration of mechanistic differential formulations at the microscopic level of description (“equations of variation”). In its turn, these equations include phenomenological terms that may be formulated in corpuscular terms in the field of Chemical Physics. The design equation correlates requirements in equipment (e.g. any practical forms of size and residence or elapsed time for an efficient interaction) to the objectives of the operation (e.g. variations in mass or energy contents of a confined or fluent system). This formulation allows the identification of different contributions: intrinsic terms (related to mechanistic kinetics of the phenomena) and circumstantial terms (related to conditions and variables of operation). Conclusion: In fact, this model suggests that temporal or spatial dimensions of the equipment may be assumed to depend irrespectively on two design contributions: the entity of a representative “unit of operation (or process)” - illustrated by a descriptor of this dimension- and the “number of (these) units” needed to achieve the separating or transformative objectives of the operation.

Abstract:

BackgroundMacrophages are immunological cells that sense microenvironmental signals that may result in the polarized expression of either proinflammatory (M1) or anti-inflammatory (M2) phenotype.1 Macrophages M2 are present in tumoral microenvironment and their presence in patients with cervical cancer (CeCa) is related with less survival.2Mesenchymal Stromal Cells (MSCs) are also present in tumor microenvironment of cervical cancer (CeCa-MSC), which have shown immunoregulatory effects over CD8 T cells, decreasing their cytotoxic effect against tumoral cells.3 Interestingly, MSCs from bone marrow (BM-MSC) decrease M1 and increase M2 macrophage polarization in an in vitro coculture system.4 Macrophages and MSCs are present in microenvironment of cervical cancer, however it is unknown if MSCs play a role in macrophage polarization. In the present study, we have evaluated the immunoregulatory capacity of CeCa-MSCs to induce macrophage polarization.MethodsCD14 monocytes were isolated from peripheral blood and cultivated in the absence or presence of MSCs from BM, normal cervix (NCx) and CeCa. Two culture conditions were included, in the presence of induction medium to favors M1 (GM-CSF, LPS and IFNg) or M2 (M-CSF, IL-4 and IL-13) macrophage polarization. M1 (HLA-DR, CD80, CD86 and IFNg) or M2 (CD14, CD163, CD206, IDO and IL-10) macrophage molecular markers were evaluated by flow cytometry. Finally, we evaluated concentration of IL-10 and TNFa in conditioned medium form all coculture conditions.ResultsWe observed that CeCa-MSCs and BM-MSCs in presence of M1 induction medium, decreased M1 macrophage markers (HLA-II, CD80, CD86 and IFNg), and increase the expression of CD14 (M2 macrophage marker). Interestingly, in presence of M2 induction medium, BM-MSCs and CaCe-MSCs but not CxN-MSC increased CD163, CD206, IDO and IL-10 (M2 macrophage markers). We observed a decreased concentration of TNFa in the supernatant medium from all cocultures with MSCs, but only in presence of CeCa-MSCs, increased IL-10 concentration was detected in such cocultures.ConclusionsIn contrast to NCx-MSCs, CeCa-MSCs similarly to BM-MSCs have in vitro capacity to decrease M1 and increase M2 macrophage phenotype.AcknowledgementsAcknowledgments The authors are indebted to gratefully acknowledge to CONACYT (Grant No. 272793) and IMSS (Grant no. 1731) for support to Juan J.
