description: We discuss a quantum deformation of the Green-Schwarz superstring on flat space, arising as a contraction limit of the corresponding deformation of AdS_5 x S^5. This contraction limit turns out to be equivalent to a previously studied limit that yields the so-called mirror model - the model obtained from the light cone gauge fixed AdS_5 x S^5 string by a double Wick rotation. Reversing this logic, the AdS_5 x S^5 superstring is the double Wick rotation of a quantum deformation of the flat space superstring. This quantum deformed flat space string realizes symmetries of timelike kappa-Poincare type, and is T dual to dS_5 x H^5, indicating interesting relations between symmetry algebras under T duality. Our results directly extend to AdS_2 x S^2 x T^6 and AdS_3 x S^3 x T^4, and beyond string theory to many (semi)symmetric space coset sigma models, such as for example a deformation of the four dimensional Minkowski sigma model with timelike kappa-Poincare symmetry. We also discuss possible null and spacelike deformations.

description: Abstract Background Leukemia/lymphoma cell lines have been critical in the investigation of the pathogenesis and therapy of hematological malignancies. While human LL cell lines have generally been found to recapitulate the primary tumors from which they were derived, appropriate characterization including cytogenetic and transcriptional assessment is crucial for assessing their clinical predictive value. Results In the following study, five canine LL cell lines, CLBL-1, Ema, TL-1 (Nody-1), UL-1, and 3132, were characterized using extensive immunophenotyping, karyotypic analysis, oligonucleotide array comparative genomic hybridization (oaCGH), and gene expression profiling. Genome-wide DNA copy number data from the cell lines were also directly compared with 299 primary canine round cell tumors to determine whether the cell lines represent primary tumors, and, if so, what subtype each most closely resembled. Conclusions Based on integrated analyses, CLBL-1 was classified as B-cell lymphoma, Ema and TL-1 as T-cell lymphoma, and UL-1 as T-cell acute lymphoblastic leukemia. 3132, originally classified as a B-cell lymphoma, was reclassified as a histiocytic sarcoma based on characteristic cytogenomic properties. In combination, these data begin to elucidate the clinical predictive value of these cell lines which will enhance the appropriate selection of in vitro models for future studies of canine hematological malignancies.

description: Quantum state engineering and quantum computation rely on information erasure procedures that, up to some fidelity, prepare a quantum object in a pure state. Such processes occur within Landauer's framework if they rely on an interaction between the object and a thermal reservoir. Landauer's principle dictates that this must dissipate a minimum quantity of heat, proportional to the entropy reduction that is incurred by the object, to the thermal reservoir. However, this lower bound is only reachable for some specific physical situations, and it is not necessarily achievable for any given reservoir. The main task of our work can be stated as the minimisation of heat dissipation given probabilistic information erasure, i.e., minimising the amount of energy transferred to the thermal reservoir as heat if we require that the probability of preparing the object in a specific pure state $|φ_1\rangle$ be no smaller than $p_{φ_1}^{\max}-δ$. Here $p_{φ_1}^{\max}$ is the maximum probability of information erasure that is permissible by the physical context, and $δ\geqslant 0$ the error. To determine the achievable minimal heat dissipation of quantum information erasure within a given physical context, we explicitly optimise over all possible unitary operators that act on the composite system of object and reservoir. Specifically, we characterise the equivalence class of such optimal unitary operators, using tools from majorisation theory, when we are restricted to finite-dimensional Hilbert spaces. Furthermore, we discuss how pure state preparation processes could be achieved with a smaller heat cost than Landauer's limit, by operating outside of Landauer's framework.

description: Gamma secretase (GS) activates notch signalling pathway (NSP) by liberating the truncated notch intracellular domain (NICD). The NSP is associated with the cancer development and progression, which makes GS a potential therapeutic target. Now day’s marine compounds emerged as a major source of bioactive entity. The NSP inhibition potential of marine-algal compounds has not yet been studied. Thus, in the present study, we have used molecular docking, molecular dynamics (MD) simulations, principal component analysis (PCA) and free energy and binding energy calculations to identify the potential GS inhibitors of marine-algal origin. Laminarin showed better docking score (−12.72) compared to the known GS inhibitor DAPT (−9.2). Laminarin formed H-Bond interaction with the Asp257 and Asp385 required for the catalytic cleavage activity of gamma-secretase. It potentially stabilised the structural parameters (RMSD, RMSF, Rg and SASA) of GS catalytic subunit compared to DAPT during the MD simulation. The PCA and free energy calculation revealed conformationally and energetically stable Laminarin–GS complex formation. Laminarin showed lower binding energy (−44.75 kcal/mol) with GS catalytic subunit than DAPT (−20.92 kcal/mol). In conclusion, the present study provides a marine-algal compound as a novel potential GS inhibitor, which requires further validation in experimental model.

description: Abstract Background Non-steroidal anti-inflammatory drugs (NSAIDs), transdermal fentanyl patches, and transmucosal buprenorphine are probably the most commonly used options for providing post-operative analgesia in the early at-home period. However, these require daily administration or are associated with abuse concerns. One of the significant unmet needs in veterinary surgery and pain management is for longer acting opioids for cats to effectively bridge the gap between the in-hospital and at-home recovery periods. A proof of concept study of an extended release formulation of buprenorphine HCL (ER-Bup) was conducted using objective kinetic measures and a unilateral onychectomy model. Using a blinded, randomized, two period crossover design, four cats were allocated to control (saline) or ER-Bup (0.6 mg/kg, subcutaneously [SC]) treatment groups. All animals underwent a unilateral forelimb onychectomy per period with a washout/recovery period in between. Observational pain scores and kinetic data (using a pressure sensitive walkway [PSW]) were collected prior to (baseline) and at intervals for 72 h following surgery. Symmetry indices were derived for kinetic variables (peak vertical force [PVF]; vertical impulse [VI]) of each forelimb for landing following a jump and for walking. A rescue analgesic protocol was in place. Effect of surgery and treatment were evaluated using a mixed model statistical approach. Results No cats required rescue analgesics based on subjective pain score. ER-Bup had a positive influence on subjective pain scores during the 72 h postsurgery (p = 0.0473). PVF and VI of the operated limb were significantly decreased for both landing (p < 0.0001 and p < 0.0001) and walking (p < 0.0001 and p < 0.0001 respectively) compared to control. ER-Bup resulted in significantly decreased asymmetry in limb use during landing (PVF, p < 0.0001; VI, p < 0.0001) and walking (PVF, p = 0.0002, VI, p < 0.0001). The novel use of data collected following a jump from an elevated platform appeared to provide all desired information and was easier to collect than walking data. Conclusion This study demonstrates that SC administration of ER-Bup may be an effective analgesic for a 72 h period postoperatively. Furthermore, landing onto a PSW from an elevated perch may be a useful and efficient way to assess analgesics in cats using a unilateral model of limb pain.

description: This study examines the relationship between religious rituals and the way people perceive moral norms. Based on the theories from anthropology, we expect that rituals charge moral symbols with which they are associated with essence. On the psychological level, this should be manifested through the facilitated perception of moral norms as independent on time, place and humans. We conducted four studies on three populations (total N = 971), showing the positive association between collective rituals and perceived objectivity of moral norms. In the final, pre-registered study, we aim at replicating the link and effect sizes found in the fourth study using new sample (N = 500) from the same population (US Christians).

description: Ачимовские отложения в Западно-Сибирском осадочно-породном мегабассейне приобретают все большее практическое значение для наращивания объемов нефтедобычи. Это сложные, гетерогенные, геологические образования, характеризуются уже общепризнанным клиноформенным строением. Среди них особую роль занимают конуса выноса турбидитных потоков. Если механизмы формирования данных отложений достаточно хорошо на качественном уровне изучены в разных областях земного шара, то количественные оценки неоднократно перемещаемого осадочного материала до сих пор затруднительны и вызывают многочисленные возражения и научные дискуссии среди специалистов-седиментологов. Обоснован выбор формулы расчета удельного транспорта «влекомых» осадков, которые имеют определяющее влияние на интенсивность и направленность развития турбидитных процессов. Представлено описание используемой численной модели, учитывающей процессы оползания и плоскостного смыва отложений. Для численной модели литодинамики подобраны параметры перемещаемых осадков (в т.ч. средний диаметр частиц), эмпирическая формула для оценки процессов транспортировки (перемещения) отложений, калибровочный множитель в формуле транспорта осадков в диапазоне от 0,3 до 1,0. На основе результатов физического моделирования выполнены расчеты объемов транспортируемых и сгруженных терригенных осадков, из которых формируются значительные по площади распространения дистальные конуса выноса.

description: Abstract Background Local anesthetics are an important component of perioperative pain management, but the duration of action of available products is limited. We hypothesized that a single local infiltration of a novel bupivacaine liposome injectable suspension (AT-003) would provide clinically effective analgesia over a 72-h period. In a masked, randomized, placebo-controlled, multi-center pilot field study, dogs undergoing lateral retinacular suture placement for cranial cruciate insufficiency were randomly assigned to surgical site infiltration with AT-003 (5.3 mg/kg) or an equivalent volume of saline. Infiltration of the surgical site was done prior to closure. Primary outcome measure was the Glasgow Composite Measure Pain Scale (CMPS-SF) assessed prior to surgery and at 2, 4, 8, 12, 24, 30, 36, 48, 54, 60 and 72 h following surgery by trained individuals. Provision for rescue analgesia was employed. Repeated measures analysis of variance were utilized to test for possible differences between treatment groups and a success/failure analysis was also employed, based on the need for rescue analgesia. Results Forty-six dogs were enrolled and evaluated. For CMPS-SF scores there was a significant overall treatment effect (p = 0.0027) in favor of AT-003. There were significantly more successes in the AT-003 group compared to placebo over each time period (p = 0.0001 for 0–24 h, p = 0.0349 for 0–48 h, and p = 0.0240 for 0-72 h). No significant adverse events were seen. Conclusions AT-003 (bupivacaine liposome injectable suspension) provided measurable local analgesia over a 72-h period following post-stifle surgery surgical site tissue infiltration. Further work is indicated to develop this product for clinical use.

description: Unidirectional light transport in one-dimensional nanomaterials at the quantum level is a crucial goal to achieve for upcoming computational devices. We here employ a full-quantum mechanical approach based on master equation to describe unidirectional light transport through a pair of two-level systems coupled to a one-dimensional waveguide. By comparing with published semi-classical results, we find that the nonlinearity of the system is reduced, thereby reducing also the unidirectional light transport efficiency. Albeit not fully efficient, we find that the considered quantum system can work as a light diode with an efficiency of approximately 60%. Our results may be used in quantum computation with classical and quantized light.
title: Politische Bauten als historisierende Repliken - Konflikte zwischen Funktionalität, Authentizität und Ästhetik
Creators: name: Baumer, Philipp
Year: 2022

description: Architektur ist eine bedeutende Trägerin gesellschaftsstiftender und politischer Narrative. Politische Institutionen sind auf allgemein als legitim betrachtete Symbole und deren kontinuierliche Akklamation angewiesen, um sich selbst und ihre politische Agenda rechtfertigen zu können. Der politischen Architektur kommt dabei die quasi exklusive Rolle als langlebige, manifeste Trägerin historisch begründeter gesellschaftlicher Identitäten zu. In Deutschland erzeugt der anhaltende Trend, öffentliche Architektur in historisierender und vordemokratischer Ästhetik wiederauferstehen zu lassen, jedoch Kontroversen hinsichtlich der politischen Legitimationsfähigkeit und des demokratischen Wertes solcher Gebäude. Durch die Entscheidung des Deutschen Bundestages und des Brandenburgischen Landtages, sich beziehungsweise anderweitige öffentliche Institutionen im Antlitz früherer preußischer Herrschaftssitze darzustellen, weisen sie einen konstituierenden Teil der jüngeren gesamtdeutschen Geschichte zurück, erschweren deren erinnerungskulturelle Aufarbeitung und erzeugen demokratiepolitische Konflikte aufgrund des Einflusses privater Eliten auf die Gestaltung des öffentlichen, politischen Raumes und dessen Symbolik. Dies schlägt sich in erinnerungspolitischen Narrativen nieder, die in parlamentarischen Diskursen um die Rekonstruktionen bedient werden. In dieser Arbeit wird versucht, diese vorgeblich gesellschaftsstiftenden, aber konfliktbehafteten Narrative in einer kritischen Diskursanalyse herauszuarbeiten.
description: Architecture is a significant carrier of societal and political narratives. Political institutions depend on symbols that are generally regarded as legitimate and on their continuous acclamation in order to justify themselves and their political agenda. Political architecture has a quasi-exclusive role as a long-lasting, manifest carrier of historically grounded social identities. In Germany, however, the ongoing trend to resurrect public architecture in historicizing and pre-democratic aesthetics generates controversy regarding the political legitimacy and democratic value of such buildings. The decision of the German Parliament and the Brandenburg State Parliament to present themselves or other public institutions in the outer cover of former Prussian seats of power rejects a constituent part of recent history of a reunited German nation, complicates its reappraisal in the culture of remembrance, and generates conflicts in the politics of democracy due to the influence of private elites on the design of public, political space and its symbolism. This is reflected in narratives of remembrance politics, which are served in parliamentary discourses about these reconstructions. This thesis attempts to elaborate these ostensible socializing narratives and the conflicts that can occur from them in a critical discourse analysis.

description: BACKGROUND: Women have generally been found to be the victims of violence, but scant attention has been paid to the characteristics of women who perpetrate aggression and violence. In South Africa, violence is a prevalent societal issue, especially in the Western Cape.

METHOD: This study aimed at identifying factors that were associated with aggression among a sample of 720 substance-using women. We conducted multivariate logistic regression to identify factors that are significantly associated with these behaviours.

RESULTS: Ethnicity (Wald Χ2 = 17.07(2), p < 0.01) and heavy drinking (Wald Χ2 = 6.60 (2), p = 0.01) were significantly related to verbal aggression, methamphetamine use was significantly related to physical (Wald Χ2 = 2.73 (2), p = 0.01) and weapon aggression (Wald Χ2 = 7.94 (2), p < 0.01) and intimate partner violence was significantly related to verbal (Wald Χ2 = 12.43 (2), p < 0.01) and physical aggression (Wald Χ2 = 25.92 (2), p < 0.01).

CONCLUSIONS: The findings show high levels of aggression among this sample, and highlight the need for interventions that address methamphetamine, heavy drinking and intimate partner violence among vulnerable substance-using women.

title: Chemodiversity of Clusia minor (Clusiaceae)
Creators: name: Kerpan, Peter
Year: 2023

description: Die Arten der Gattung Clusia (Clusiaceae) sind verholzende Pflanzen der Neotropen und werden hauptsächlich bezüglich ihrer Fotosynthesestrategien analysiert. Clusia Arten akkumulieren jedoch auch spezielle Pflanzenmetabolite (SPM) von auffälligen Strukturen und bioaktiven Eigenschaften. Die Arten dieser Gattung zeigen eine Tendenz zur Biosynthese von Stoffen aus dem Phenylpropanoidstoffwechsel, oftmals in Kombination mit Bausteinen aus dem Terpenoid- und Polyketidstoffwechsel. Innerhalb des Pflanzenreichs ist die Gattung besonders bekannt für die Akkumulation von Benzophenonderivaten. Ziel der vorliegenden Arbeit war es, die Chemodiversität von Clusia minor in Bezug auf die SPM eingehender zu untersuchen. Zu diesem Zwecke wurden Wurzeln dieser Pflanzenart für eingehende phytochemische Analyse ausgewählt, wobei standardisierte chromatographische Techniken zur Auftrennung des Extrakts und zu Isolierung der SPM eingesetzt wurden. Die Identifikation der Strukturen isolierte Verbindungen erfolgte durch Interpretation von MS- und NMR- Daten. Insgesamt konnten fünf Verbindungen isoliert werden, von denen drei strukturell eindeutig identifiziert werden konnten. Zwei Stoffe erwiesen sich als Tocotrienol-Derivate (Z-δ-Garcinoic Acid und δ-Tocotrienol). Basierend auf NMR- und MS-Daten konnte die dritte Verbindung als ein neues Benzophenon-Derivat identifiziert werden, welches durch eine ungewöhnliche fünfteilige Ringstruktur gekennzeichnet ist und als Minoron bezeichnet wurde. Darüber hinaus wird die bisher bekannte Literatur in Bezug auf Chemodiversität der SPM ausgewertet und umfassend diskutiert.
description: The species of the neotropical woody plants in the genus Clusia (Clusiaceae) are primarily researched for their photosynthetic strategies. However, Clusia spp. are also remarkable sources of peculiar and bioactive specialized plant metabolites (SPM). The members of this genus appear to predominantly produce compounds derived from the phenlypropanoid biosynthetic pathway, in combination with terpenoid and the polyketide pathways. Clusia is noted particularly for the most abundant occurrence of benzophenone derivatives in plants. The aim of the present study was to further enhance the knowledge on the SPM chemodiversity of this genus. For this purpose, root extracts of C. minor were chosen for a detailed phytochemical analysis, applying standard chromatographic techniques for separation and isolation. Structure identification of isolated compounds was achieved by MS and NMR data. Of the five isolated compounds, three of them could be structurally characterized. They comprised two substances, which are related to tocotrienols (Z-δ-garcinoic acid and δ-tocotrienol), and a further one relating to benzophenones, respectively. The latter is a hitherto undescribed compound with a peculiar 5-membered cycle, for which the name minorone was designated. In addition, current knowledge on the SPM chemodiversity of Clusia spp. is summarized and discussed extensively.

description: STUDY QUESTION: What has been the effect on purchases of beverages from stores in Mexico one year after implementation of the excise tax on sugar sweetened beverages?

METHODS: In this observational study the authors used data on the purchase of beverages in Mexico from January 2012 to December 2014 from an unbalanced panel of 6253 households providing 205 112 observations in 53 cities with more than 50 000 inhabitants. To test whether the post-tax trend in purchases was significantly different from the pretax trend, the authors used a difference in difference fixed effects model, which adjusts for both macroeconomic variables that can affect the purchase of beverages over time, and pre-existing trends. The variables used in the analysis included demographic information on household composition (age and sex of household members) and socioeconomic status (low, middle, and high). The authors compared the predicted volumes (mL/capita/day) of taxed and untaxed beverages purchased in 2014-the observed post-tax period-with the estimated volumes that would have been purchased if the tax had not been implemented (counterfactual) based on pretax trends.

STUDY ANSWER AND LIMITATIONS: Relative to the counterfactual in 2014, purchases of taxed beverages decreased by an average of 6% (-12 mL/capita/day), and decreased at an increasing rate up to a 12% decline by December 2014. All three socioeconomic groups reduced purchases of taxed beverages, but reductions were higher among the households of low socioeconomic status, averaging a 9% decline during 2014, and up to a 17% decrease by December 2014 compared with pretax trends. Purchases of untaxed beverages were 4% (36 mL/capita/day) higher than the counterfactual, mainly driven by an increase in purchases of bottled plain water.

WHAT THIS STUDY ADDS: The tax on sugar sweetened beverages was associated with reductions in purchases of taxed beverages and increases in purchases of untaxed beverages. Continued monitoring is needed to understand purchases longer term, potential substitutions, and health implications.

description: The ensemble Kalman filter (EnKF) and ensemble square root filter (ESRF) are data assimilation methods used to combine high dimensional, nonlinear dynamical models with observed data. Despite their widespread usage in climate science and oil reservoir simulation, very little is known about the long-time behavior of these methods and why they are effective when applied with modest ensemble sizes in large dimensional turbulent dynamical systems. By following the basic principles of energy dissipation and controllability of filters, this paper establishes a simple, systematic and rigorous framework for the nonlinear analysis of EnKF and ESRF with arbitrary ensemble size, focusing on the dynamical properties of boundedness and geometric ergodicity. The time uniform boundedness guarantees that the filter estimate will not diverge to machine infinity in finite time, which is a potential threat for EnKF and ESQF known as the catastrophic filter divergence. Geometric ergodicity ensures in addition that the filter has a unique invariant measure and that initialization errors will dissipate exponentially in time. We establish these results by introducing a natural notion of observable energy dissipation. The time uniform bound is achieved through a simple Lyapunov function argument, this result applies to systems with complete observations and strong kinetic energy dissipation, but also to concrete examples with incomplete observations. With the Lyapunov function argument established, the geometric ergodicity is obtained by verifying the controllability of the filter processes; in particular, such analysis for ESQF relies on a careful multivariate perturbation analysis of the covariance eigen-structure.

description: Consumer foraging behaviors are dynamic, changing in response to prey availability, seasonality, competition, and even the consumer's physiological state. The isotopic composition of a consumer is a product of these factors as well as the isotopic 'landscape' of its prey, i.e. the isotopic mixing space. Here we build a mechanistic framework that links the ecological and physiological processes of an individual consumer to the isotopic distribution that describes its diet, and ultimately to the isotopic composition of its own tissues, defined as its 'isotopic niche'. By coupling these processes, we systematically investigate under what conditions the isotopic niche of a consumer changes as a function of both the geometric properties of its mixing space and foraging strategies that may be static or dynamic over time. Results of our derivations reveal general insight into the conditions impacting isotopic niche width as a function of consumer specialization on prey, as well as the consumer's ability to transition between diets over time. We show analytically that moderate specialization on isotopically unique prey can serve to maximize a consumer's isotopic niche width, while temporally dynamic diets will tend to result in peak isotopic variance during dietary transitions. We demonstrate the relevance of our theoretical findings by examining a marine system composed of nine invertebrate species commonly consumed by sea otters. In general, our analytical framework highlights the complex interplay of mixing space geometry and consumer dietary behavior in driving expansion and contraction of the isotopic niche. Because this approach is established on ecological mechanism, it is well-suited for enhancing the ecological interpretation, and uncovering the root causes, of observed isotopic data.
