description: Background: A label’s entrenchment, its degree of use by a community, affects perceived explanatory value even if the label contains no substantive information (Hemmatian & Sloman, 2018). It has been argued that confusing social utility of labels (their usefulness in conversations) with their epistemic utility (the explanatory information they provide) is behind the effect. In five experiments, we examine whether laypeople and mental health professionals see entrenched psychiatric and non-psychiatric diagnostic labels as better explanations than non-entrenched labels even if they carry no information, and test explanations for the effect that rely on confusing social and epistemic utility. Methods: Using scenarios involving experts who discuss unfamiliar diagnostic categories, we manipulated entrenchment and type of disorder. In unentrenched conditions, experts named the malady with an uncommon label. Entrenched labels were commonly employed. In Experiments 1a and 2, the labels’ descriptive and etiological informativeness were independently manipulated. The pre-registered experiment 3 controlled for interventional and predictive utility of labels and separately measured perceived social and epistemic usefulness as a function of entrenchment. Experiment 4 extended the results to mental health professionals. Experiment 1b is a pre-registered replication of Experiment 1 with separate DVs for social and epistemic utility as well as additional probing questions. Results: Across experiments, common use increased the perceived epistemic utility of labels, sometimes inducing beliefs that contradicted provided information. This preference is not due to conversational norms, lack of reflectiveness or attentiveness, disbelief in scenario contents, memory failures and the characters’ familiarity with the label. Bringing experts’--but not laypeople’s--attention to the manipulation eliminated the effect. Conclusion: Hints to common use of diagnostic labels cause both laypeople and experts to conflate it with informational value, even when provided with direct information to the contrary. Our data highlights several ways to diminish this effect. We discuss implications for patients’ perceptions of their named conditions and the persistence of dubious diagnoses in expert parlance.

description: We study the moduli spaces of self-dual instantons on CP^2 in a simple group G. When G is a classical group, these instanton solutions can be realised using ADHM-like constructions which can be naturally embedded into certain three dimensional quiver gauge theories with 4 supercharges. The topological data for such instanton bundles and their relations to the quiver gauge theories are described. Based on such gauge theory constructions, we compute the Hilbert series of the moduli spaces of instantons that correspond to various configurations. The results turn out to be equal to the Hilbert series of their counterparts on C^2 upon an appropriate mapping, in agreement with the result of [arXiv:0802.3120]. We check the former against the Hilbert series derived from the blowup formula for the Hirzebruch surface F_1 and find an agreement. The connection between the moduli spaces of instantons on such two spaces is explained in detail.

description: The sex-inducing pheromone of Volvox carteri is a glycoprotein that triggers development of males and females at a concentration below 10(-16) M. Evidence is presented for the existence of a novel mechanism of signal amplification operating within the extracellular matrix of this multicellular organism. A family of 70 kDa matrix glycoproteins denoted pherophorins bear a C-terminal domain being homologous to the sex-inducing pheromone. Under the influence of the pheromone, this domain is liberated by highly specific proteolysis.

description: The multicellular green flagellate Volvox carteri synthesizes a periplasmic arylsulfatase in response to sulfur deprivation. The inducible enzyme has been purified to homogeneity and characterized. The corresponding gene and cDNA have been cloned. Determination of the sequence of genomic clones and comparisons to the cDNA sequence, revealed sixteen introns and seventeen exons that encode a 649-amino-acid polypeptide chain. Since the arylsulfatase enzyme is readily assayed using chromogenic substrates, but is not detectable in cells grown in sulfate-containing medium, the gene encoding arylsulfatase may be useful as a reporter gene in V. carteri. In addition, the highly regulated promoter of the arylsulfatase gene suggests its suitability as a tool for producing inducible expression vectors for cloned genes.

description: Geflüchtete Menschen mit B- oder F-Ausweis halten sich oft für längere Zeit in der Schweiz auf, besitzen jedoch kein aktives und passives Wahlrecht. Diese Arbeit analysiert, welche politischen und rechtlichen Grundlagen in der Schweiz für Menschen mit Fluchterfahrung für die politische Partizipation bestehen, was Hindernisse und Ressourcen für die politische Beteiligung darstellen und welche Handlungsprinzipien für soziokulturelle Animator*innen dabei zu beachten sind. Im Anschluss wird durch die Autorin Tamara Fischer aufgezeigt, welche Handlungsmassnahmen von soziokulturellen Animator*innen empfehlenswert sind, um die politische Partizipation der Zielgruppe zu stärken. Die Verfasserin der Bachelorarbeit arbeitete selbst als Integrationsbeauftragte in einer Gemeinde und kennt die Bedürfnisse der Geflüchteten sowie die strukturellen Hürden, die für sie bestehen. Mit dieser Arbeit möchte sie Fachpersonen aufzeigen, wie sie Menschen mit Fluchtgeschichte ermächtigen können, ihre Position zu reflektieren und sich politisch zu beteiligen. Die Fachliteraturarbeit zeigt, dass für die politische Partizipation in der Schweiz die Willkommenskultur der Schweiz und den Entscheidungstragenden und das Aufzeigen der Chancenungleichheit seitens der Fachpersonen der soziokulturellen Animation zentral ist. Weiter wurde aufgezeigt, dass nicht eine Massnahme allein die Situation für die Zielgruppe verändert, sondern dass sich für die verschiedenen Probleme unterschiedliche Lösungen und Handlungsmassnahmen anbieten. Für viele Handlungsmassnahmen wurde im Anhang eine Liste mit weiterführenden Beispielen und Websites zusammengestellt.

description: ISG is a sulphated, extracellular glycoprotein synthesized for only a few minutes in inverting Volvox embryos and inverting sperm cell packets. This control operates at the level of transcription. ISG has been characterized by studies of protein chemistry and electron microscopy. The primary structure of ISG has been derived from genomic DNA and cDNA. ISG is composed of a globular and a rod-shaped domain. The rod-shaped domain represents a member of the extensin family with numerous repeats of Ser-(Hyp)4-6 motifs. A synthetic decapeptide matching the C-terminal sequence is able to disaggregate the organism into individual cells. Immunofluorescence microscopy localizes ISG within the boundary zone of the ECM.

description: In der Sozialen Arbeit ist es vor allem die Sozialpädagogik, die Erziehungsprozesse im Rahmen ihrer Zuständigkeit für Sozialisation unterstützt. Die Heimerziehung stellt den Kernbereich der sozialpädagogischen Praxis dar. Sozialpädagogisches Fachpersonal in stationären Einrichtungen ist täglich mit dem Führen und Umsetzen von Erziehungsprozessen konfrontiert. Die Erziehung an sich beruht auf grundlegenden Wertvorstellungen. Aufgezeigt wird, wie sich die normativen Erziehungsgrundlagen erklären und welche Bedeutung sie auf die stationäre Kinder- und Jugendhilfe haben. Normen der Erziehung werden durch aktuelle soziale Normen geprägt. Eine normative Erziehung ist seinerseits wieder beeinflusst von sozialen Normen. Somit besteht eine Interdependenz zwischen diesen Normen. Mittels der Fachliteraturarbeit wird aufgezeigt, dass eine vertiefte Auseinandersetzung mit Erziehung und Normen sowie deren Wechselwirkung notwendig ist. Die Ergebnisse zeigen auf, dass in der sozialpädagogischen Praxis ein diffuses und wenig greifbares Erziehungsverständnis vorherrscht. Dies wird darauf zurückgeführt, dass grössere Defizite in der theoretischen Wissensvermittlung sowie im dialogischen Diskurs über die Erziehung vorhanden sind.

description: The extracellular matrix (ECM) of Volvox contains insoluble fibrous layers that surround individual cells at a distance to form contiguous cellular compartments. Using immunological techniques, we identified a sulfated surface glycoprotein (SSG 185) as the monomeric precursor of this substructure within the ECM. The primary structure of the SSG 185 poly-peptide chain has been derived from cDNA and genomic DNA. A central domain of the protein, 80 amino acid residues long, consists almost exclusively of hydroxyproline residues. The chemical structure of the highly sulfated polysaccharide covalently attached to SSG 185 has been determined by permethylation analysis. As revealed by EM, SSG 185 is a rod-shaped molecule with a 21-nm-long polysaccharide strand protruding from its central region. The chemical nature of the cross-links between SSG 185 monomers is discussed.

We use this operation to produce multiple constructions of symplectic smoothly exotic complex projective space blown-up eight times, seven times, and six times. We also show how this operation can be used in conjunction with knot surgery to construct an infinite family of minimal exotic smooth structures on the complex projective space blown-up seven times.

Mean field games via controlled martingale problems: Existence of Markovian equilibria

Subjects: subject: Probability (math.PR)

description: Mean field games are studied in the framework of controlled martingale problems, and general existence theorems are proven in which the equilibrium control is Markovian. The framework is flexible enough to include degenerate volatility, which may depend on both the control and the mean field. The objectives need not be strictly convex, and the mean field interactions considered are nonlocal and Wasserstein-continuous. When the volatility is nondegenerate, continuity assumptions may be weakened considerably. The proofs first use relaxed controls to establish existence. Then, using a convexity assumption and measurable selection arguments, strict (non-relaxed) Markovian equilibria are constructed from relaxed equilibria.

At the genomic level, the sexual inducer protein is encoded in five exons.

description: We present the first theoretical prediction of the production rate of $1^{-+}$ light hybrid meson $η_1$ in $J/ψ$ radiative decays. In the $N_f=2$ lattice QCD formalism with the pion mass $m_π\approx 350$ MeV, the related electromagnetic multipole form factors are extracted from the three-point functions that involve necessarily quark annihilation diagrams, which are calculated through the distillation method. The partial width of $J/ψ\to γη_1$ is determined to be $2.29(77)~\mathrm{eV}$ at the $η_1$ mass $m_{η_1}=2.23(4)$ GeV. If $η_1$ corresponds to the recently observed $η_1(1855)$ in the process $J/ψ\to γη_1(1855)\to γηη'$ by BESIII, then the branching fraction $\mathrm{Br}(J/ψ\to γη_1(1855))$ is estimated to be $6.2(2.2)\times 10^{-5}$, which implies $\mathrm{Br}(η_1(1855)\to ηη')\sim 4.3\%$.

description: The sexual inducer of Volvox carteri f. nagariensis is a glycoprotein and one of the most potent biological effector molecules known. It is synthesized by sperm cells and converts asexually growing males and females to the sexual pathway. Until now, large-scale production of the inducer was made impossible by an inherent biological ;switch' mechanism, the spontaneous self-induction of asexually growing males. Here we describe a method overcoming this problem for the first time. Large-scale production and purification allowed a detailed chemical characterization of the inducer with respect to partial amino acid sequences and sugar composition. Chemically synthesized oligodeoxynucleotides corresponding to derived amino acid sequences were used to screen a genomic gene bank of V. carteri HK 10. A positive clone (Ind-28) was shown to encode the inducer gene by subcloning and sequencing.
Structural instability and the Mott-Peierls transition in a half-metallic hollandite : K$_{2}$Cr$_{8}$O$_{16}$

description: In order to explore the driving mechanism of the concomitant metal-insulator and structural transitions in quasi-one-dimensional hollandite K$_{2}$Cr$_{8}$O$_{16}$, electronic structures and phonon properties are investigated by employing the {\it ab initio} density functional theory (DFT) calculations. We have found that the imaginary phonon frequency reflecting the structural instability appears only in the DFT+$U$ ($U$: Coulomb correlation) calculation, which indicates that the Coulomb correlation plays an essential role in the structural transition. The lattice displacements of the softened phonon at X explain the observed lattice distortions in K$_{2}$Cr$_{8}$O$_{16}$ perfectly well, suggesting the Peierls distortion vector {\bf Q} of X (0, 0, 1/2). The combined study of electronic and phonon properties reveals that half-metallic K$_{2}$Cr$_{8}$O$_{16}$, upon cooling, undergoes the correlation-assisted Peierls transition to become a Mott-Peierls ferromagnetic insulator at low temperature.

description: Collective behavior of proteins on biomembranes is usually studied within the spontaneous curvature model. Here we consider an alternative phenomenological approach, which accounts consistently for partial ordering of proteins as well as the anchoring forces exerted on a membrane by layer of proteins. We show analytically that such anisotropic interactions can drive membrane bending, resulting in non-trivial equilibrium morphologies. The predicted instabilities can advance our conceptual understanding of physical mechanisms behind collective phenomena in biological systems, in particular those with inherent anisotropy.

description: In this article we show the existence of closed embedded self-shrinkers in $\Bbb{R}^{n+1}$ that are topologically of type $S^1\times M$, where $M\subset S^n$ is any isoparametric hypersurface in $S^n$ for which the multiplicities of the principle curvatures agree. This yields new examples of closed self-shrinkers, for example self-shrinkers of topological type $S^1\times S^k\times S^k\subset \Bbb R^{2k+2}$ for any $k$. If the number of distinct principle curvatures of $M$ is one the resulting self-shrinker is topologically $S^1\times S^{n-1}$ and the construction recovers Angenent's shrinking doughnut.

description: Nachbarschaftsnetzwerke sind soziale Räume, die zu den Ressourcen und zum Sozialkapital der Beteiligten zählen. Diese Ressourcen sind insbesondere in Quartieren wesentlich, die über wenig Infrastruktur verfügen, als unattraktiv gelten und eine hohe Anzahl Personen mit niedrigem sozioökonomischem Status aufweisen. Ein solch benachteiligtes Quartier ist das Riethofquartier in der Zürcher Gemeinde Opfikon, die dem suburbanen Raum – auch Agglomeration genannt – angehört. Anhand dieses Beispiels untersucht die vorliegende Arbeit die Frage, wie Nachbarschaftsnetzwerke in benachteiligten Quartieren der Agglomeration beschaffen sind und welcher Handlungsbedarf für die Soziokulturelle Animation besteht. Nach einer teilstrukturierten Beobachtung werden die nachbarschaftlichen Netzwerke in drei Leitfaden-Interviews mit Anwohner*innen des Riethofquartiers explorativ erforscht. Diese Befragungen ergeben ein diverses Bild von Beziehungen und Ansichten zum Quartier. Es zeigt sich, dass das Erfassen und Einschätzen dieser Beziehungen anhand gängiger Kategorien und ohne Dialog mit den betroffenen Personen nicht möglich ist. Um Nachbarschaftsnetzwerke zu stärken, sind Möglichkeiten zur Vernetzung der Anwohner*innen sowie zur Identifikation mit dem eigenen Wohnort wichtig. Für die Soziokulturelle Animation empfiehlt sich ein lebensweltorientiertes Arbeiten, das auf den vorhandenen Ressourcen und der Perspektive der Quartierbevölkerung basiert. Nicht das Fördern und Formen von Beziehungen durch Fachpersonen, sondern die Teilhabe der Bewohner*innen am politischen und gesellschaftlichen Geschehen sowie an Entscheidungen, die «ihren» Sozialraum betreffen, stehen im Vordergrund.

description: Während viele Angebote der Kinder- und Jugendhilfe nach wie vor auf ein binäres Geschlechterverständnis ausgerichtet sind, steigen die Zahlen von Jugendlichen, die sich als trans*, inter* oder non-binär outen und sich nicht in ein zweigeschlechtliches Kategoriensystem einfügen lassen. In geschlechtergetrennten Angeboten wird die binäre Strukturierung besonders deutlich und erschwert eine bedürfnisgerechte Integration und Betreuung nicht-cisgeschlechtlicher Jugendlicher. In geschlossenen, geschlechtergetrennten Institutionen drängt sich diese Diskrepanz auf, da in Situationen, die eine geschlossene Platzierung erfordern, häufig keine Alternativen zur Verfügung stehen. Anhand von Gruppendiskussionen mit Mitarbeitenden einer Wohngruppe für weibliche und einer Wohngruppe für männliche Jugendliche sowie Interviews mit den beiden Leitungspersonen wird untersucht, inwiefern ein affirmativer Umgang mit Geschlechtervielfalt in geschlossenen, geschlechtergetrennten Wohngruppen umgesetzt wird und welche spezifischen Herausforderungen sich dabei für die Institutionen und Mitarbeitenden stellen. Die generierten Daten werden anhand einer inhaltlich strukturierenden qualitativen Inhaltsanalyse ausgewertet. Es zeigt sich, dass sich beide untersuchten Institutionen im Prozess befinden, die Betreuung von nicht-cisgeschlechtlichen Jugendlichen zu optimieren und bedürfnisgerecht zu gestalten. Es werden zahlreiche queer-inklusive Handlungsweisen umgesetzt. Die Herausforderungen, welche sich stellen, sind insbesondere eine generelle mangelnde Handlungssicherheit im pädagogischen Alltag mit trans* oder non-binären Jugendlichen, der Umgang mit Urinproben und Leibesvisitationen, die Frage nach der notwendigen Gewichtung der Thematik, der Umgang mit den anderen Jugendlichen auf der Wohngruppe sowie der Umgang mit dem Spannungsfeld zwischen biologischem Geschlecht, Rollenverhalten und Bedürfnisgerechtigkeit des Angebotes

description: Um adäquate Unterstützungsmassnahmen zu initiieren und damit negative Konsequenzen zu reduzieren oder gar zu verhindern, hat die Früherkennung von potentiellen Kindeswohlgefährdungen eine grosse Bedeutung. Dabei nimmt die Schule eine zentrale Rolle ein. Diverse Publikationen bezeichnen Schulsozialarbeitende als prädestinierte Fachpersonen für kindesschutzrelevante Themen im System Schule. Die Fallorganisation fungiert als Strukturierungsinstrument, doch dieses Konzept ist in der Fachliteratur kaum zu finden. Die vorliegende Masterarbeit möchte diese Lücke schliessen und ein Konzept der ganzheitlichen Betrachtungsweise für die Fallorganisation von potentiellen Kindeswohlgefährdungen entwickeln. Diese besteht aus den vier Faktoren der strukturellen Rahmenbedingungen, der Auftragsklärung, der Fallführung und der interdisziplinären Kooperation. Im Rahmen einer vergleichenden Fallstudie wird die Fallorganisation sowie die Rolle von Schulsozialarbeitenden auf Primarstufe im Kanton Basel-Landschaft untersucht. Das Forschungsdesign umfasst zwei Phasen. Im Rahmen einer Aktenanalyse werden Falldokumentationen von zwei Schulsozialarbeitenden ausgewertet. Diese erlauben eine Annäherung an die Praxis und bilden die Basis für die anschliessenden Interviews mit vier Expert:innen. Die Ergebnisse der beiden Forschungsphasen werden mit dem vorangehenden Theorieteil in Zusammenhang gebracht. Alle vier Faktoren sind relevant bei der Fallorganisation und die Schulsozialarbeit sollte dabei die Rolle als Fachperson für Kindesschutz im Kontext Schule einnehmen. Doch zwischen Theorie und Praxis bestehen Differenzen und somit ein Entwicklungspotential in der Praxis. Aus diesem Grund werden umfangreiche Handlungsempfehlungen für Schulsozialarbeitende auf Primarstufe im Kanton BaselLandschaft abgeleitet.

description: We report the chemical characterization of the highly sulphated glycoprotein SSG 185 from Volvox carteri. SSG 185 is a hydroxyproline-containing, extracellular glycoprotein. The sulphate residues are clustered within the parent saccharide structure of SSG 185, since on mercaptolysis all the sulphate residues are recovered in a small saccharide fragment containing mannose, arabinose and sulphate (in a molar ratio of 112). SSG 185 is a short-lived molecule, serving as a precursor for a high mol. wt. component of the extracellular matrix. Synthesis of SSG 185 is developmentally controlled. Different SSG 185 variants, with unknown modifications in the sulphated saccharide fragment, are synthesized at different developmental stages or under the influence of the sexual inducer. These modifications remain conserved in the aggregated state of SSG 185, indicating the development-dependent modification of the extracellular matrix.

description: Memristors are promising devices for scalable andlow power, in-memory computing to improve the energy efficiencyof a rising computational demand. The crossbar array architecturewith memristors is used for vector matrix multiplication(VMM) and acts as kernels in neuromorphic computing. Theanalog conductance control in a memristor is achieved byapplying voltage or current through it. A basic 1T1R arrayis suitable to avoid sneak path issues but suffer from wireresistances, which affects the read and write procedures. Aconductance control scheme with a regulated voltage sourcewill improve the architecture and reduce the possible potentialdivider effects. A change in conductance is also possible with theprovision of a regulated current source and measuring the voltageacross the memristors. A regulated 2T1R memristor conductancecontrol architecture is proposed in this work, which avoids thepotential divider effect and virtual ground scenario in a regularcrossbar scheme, as well as conductance control by passing aregulated current through memristors. The sneak path currentis not allowed to pass by the provision of ground potential toboth terminals of memristors.

description: 1. Unidirectional efflux of 36Cl- and H14CO3- from erythrocytes of 4- to 16-day-old chick embryos was measured under steady-state conditions at 37 degrees C and pH 7.7. The efflux rates were high, > 3 s-1, and were, therefore, measured by means of the continuous flow tube method. 2. At day 4 of development the range of permeability coefficients for bicarbonate and chloride (PHCO3 and PCl was 1-30 x 10(-4) cm s-1, with average values of respectively 10 x 10(-4) and 8 x 10(-4) cm s-1. However, the results can be divided into two groups, one with PHCO3 and PCl above 12 x 10(-4) cm s-1, and one with values below 5 x 10(-4) cm s-1. The same range of values was also obtained for day 6 erythrocytes, but the overlap is more conspicuous. At day 16, PHCO3 and PCl were respectively 9 x 10(-4) and 6 x 10(-4) cm s-1 (37 degrees C, pH 7.7). In adult chicken red blood cells PHCO3 and PCl were respectively 7 x 10(-4) and 4 x 10(-4) cm s-1, and in human red blood cells the respective values were 5.6 x 10(-4) and 4 x 10(-4) cm s-1. 3. Chloride self-exchange, measured at 0 degrees C, was almost completely inhibited by addition of 1 mM 4,4'-diisothiocyanostilbene-2,2'-disulphonate (DIDS) at both days 6 and 16 of embryonic development, supporting the finding that the embryonic chick erythrocytes also have a transmembrane anion exchanger similar to that of other red cells.(ABSTRACT TRUNCATED AT 250 WORDS)

description: In der vorliegenden, explorativen Forschungsarbeit sollten die Herausforderungen geflüchteter Jugendlichen im Integrationsprozess der Schweiz, insbesondere in Bezug auf Rassismus- und Diskriminierungserfahrungen erforscht werden. Damit ein Gesamtbild zur Lebenssituation von geflüchteten Jugendlichen entsteht, werden die Entwicklungsaufgaben im Jugendalter sowie die Flucht und die damit verbundenen Herausforderungen erläutert. Dabei spielen die Ziele der Integrationsagenda Schweiz, die von den kantonalen Integrationsprogrammen umgesetzt werden, eine essenzielle Rolle. Zuletzt wird auf das Thema Rassismus und Diskriminierung in der Schweiz eingegangen. Insgesamt wurden sechs geflüchtete Jugendliche anhand eines Leitfadeninterviews befragt und die daraus entstandenen Informationen durch die inhaltlich strukturierende qualitative Inhaltsanalyse nach Kuckartz und Rädiker ausgewertet. Die Ergebnisse zeigen, dass Jugendliche vor allem das Lernen der deutschen Sprache als herausfordernd empfanden. Durch die Wohnumstände in Durchgangs- und Asylzentren, den Aufenthaltsstatus sowie Rassismus- und Diskriminierungserfahrungen wurde die Integration erschwert. Demzufolge sollten die Jugendlichen eine intensivere und auf ihre Bedürfnisse ausgerichtete Betreuung durch die Fachpersonen erhalten. Ebenfalls sollten mehr Beschwerdemöglichkeiten für erlebte Rassismus- und Diskriminierungserfahrungen geschaffen werden. Aus diesen Aspekten erschliesst sich der Titel der vorliegenden Bachelorarbeit: ,,Herausforderungen von geflüchteten Jugendlichen im Integrationsprozess – Eine explorative Forschungsarbeit zu Rassismus- und Diskriminierungserfahrungen im Kanton Schwyz’’.

description: Doping of a two-dimensional (2D) material by impurity atoms occurs \textit{via} two distinct mechanisms: absorption of the dopants by the 2D crystal or adsorption on its surface. To distinguish the relevant mechanism, we systematically dope 53 experimentally synthesized 2D monolayers by 65 different chemical elements in both absorption and adsorption sites. The resulting 17,598 doped monolayer structures were generated using the newly developed ASE \texttt{DefectBuilder} -- a Python tool to set up point defects in 2D and bulk materials -- and subsequently relaxed by an automated high-throughput density functional theory (DFT) workflow. We find that interstitial positions are preferred for small dopants with partially filled valence electrons in host materials with large lattice parameters. On the contrary, adatoms are favored for dopants with a low number of valence electrons due to lower coordination of adsorption sites compared to interstitials. The relaxed structures, characterization parameters, defect formation energies, and magnetic moments (spins) are available in an open database to help advance our understanding of defects in 2D materials.

description: Red cell carbonic anhydrase activity, 2.3 DPG concentration, and activities of three key enzymes controlling DPG metabolism (PK, PFK and DPGM) were measured in normoxic and hypoxic (incubation in 13.5% O2) chick embryos. In normoxia 2.3 DPG concentration and carbonic anhydrase activity begin to increase by the third week of incubation. Hypoxia induces a rise of 2.3 DPG concentration and carbonic anhydrase activity by Day 8 of development, i.e., 1 week earlier. Since during normal development chick embryos become hypoxic in the third week of incubation, the results suggest that PO2 has a controlling influence on the timing of differentiation events of definitive embryonic red cells.

Superradiant instability of the charged scalar field in stringy black hole mirror system

description: It has been shown that the mass of the scalar field in the charged stringy black hole is never able to generate a potential well outside the event horizon to trap the superradiant modes. This is to say that the charged stringy black hole is stable against the massive charged scalar perturbation. In this paper we will study the superradiant instability of the massless scalar field in the background of charged stringy black hole due to a mirror-like boundary condition. The analytical expression of the unstable superradiant modes is derived by using the asymptotic matching method. It is also pointed out that the black hole mirror system becomes extremely unstable for a large charge $q$ of scalar field and the small mirror radius $r_m$.

Sulfation of a cell surface glycoprotein correlates with the developmental program during embryogenesis of Volvox carteri

description: A sulfated cell surface glycoprotein with an apparent molecular weight of 185,000 is synthesized in the multicellular organism Volvox only during the limited period of embryogenesis. The lifetime of sulfate residues on this glycoprotein is very short (half-life about 20 min). Production of this sulfated glycoprotein sharply decreases to a minimum shortly before the onset of the differentiating cell cleavage--e.g., in asexual development, before the 32-cell embryo divides. It is demonstrated that the sulfated glycoprotein behaves in many respects as would the hypothetical cell surface component postulated by a recently published model [Sumper, M. (1979) FEBS Lett. 107, 241-246], which proposes an explanation for the cell-counting mechanism and the spatial control of differentiation that is operative in Volvox embryogenesis.
Replica symmetry breaking in the Bose glass

description: We investigate the nature of the Bose glass phase of the disordered Bose-Hubbard model in $d>2$ and demonstrate the existence of a glass-like replica symmetry breaking (RSB) order parameter in terms of particle number fluctuations. Starting from a strong-coupling expansion around the atomic limit, we study the instability of the Mott insulator towards the formation of a Bose glass. We add some infinitesimal RSB, following the Parisi hierarchical approach in the most general form, and observe its flow under the momentum-shell renormalization group scheme. We find a new fixed point with one-step RSB, corresponding to the transition between the Mott insulator and a Bose glass phase with hitherto unseen RSB. The susceptibility associated to infinitesimal RSB perturbation in the Mott insulator is found to diverge at the transition with an exponent of $γ=1/d$. Our findings are consistent with the expectation of glassy behavior and the established breakdown of self-averaging. We discuss the possibility of measuring the glass-like order parameter in optical lattice experiments as well as in certain spin systems that are in the same universality class as the Bose-Hubbard model.

Soziale Arbeit

description: Der Hintergrund der vorliegenden Masterthesis ist die These, dass das Verhältnis zwischen Sozialer Arbeit und früher Kindheit in der Schweiz ungeklärt ist. Um den Versuch einer Klärung zu unternehmen, wurde untersucht, wie die Soziale Arbeit in Disziplin und Praxis der frühen Kindheit verortet ist. Wichtige Aspekte aus dieser Untersuchung wurden in Bezug zu Theorien der Sozialen Arbeit gesetzt. Aus der Vermengung der Erkenntnisse aus der Praxis, der Disziplin und der Theorie der Sozialen Arbeit in der frühen Kindheit kann festgestellt werden, dass Soziale Arbeit in der frühen Kindheit ethisch von der UN-Kinderrechtskonvention und von den mit den Kinderrechten korrespondierenden Konzepten von Child well-being und Agency geleitet ist. In Praxisfeldern wie der Sozialpolitik, dem Kindesschutz, der Familienbegleitung und -beratung, den Familien- und Quartierzentren und der Kinderbetreuung handelt die Soziale Arbeit mit dem Ziel des Schutzes, der Inklusion, der Bildung und der Prävention. Um ihre Ziele zu erreichen, geht die Soziale Arbeit in der frühen Kindheit professionelle Kooperationen ein und agiert multidisziplinär. Dabei vertritt sie ihr übergeordnetes Ziel der absichtslosen Ermöglichung der guten frühen Kindheit mit dem Hinweis auf ihre ethische Legitimation.
