AdS_3 backgrounds from 10D effective action of heterotic string theory

description: We present a method for calculating solutions and corresponding central charges for backgrounds with AdS_3 and S^k factors in alpha'-exact fashion from the full tree-level low energy effective action of heterotic string theory. Three examples are explicitly presented: AdS_3 X S^3 X T^4, AdS_3 X S^2 X S^1 X T^4 and AdS_3 X S^3 X S^3 X S^1. Crucial property which enabled our analysis is vanishing of the Riemann tensor calculated from connection with "sigma-model torsion". We show the following: (i) Chern-Simons terms are the only source of alpha'-corrections not only in BPS, but also in non-BPS cases, suggesting a possible extension of general method of Kraus and Larsen, (ii) our results are in agreement with some conjectures on the form of the part of tree-level Lagrangian not connected to mixed Cern-Simons term by supersymmetry (and present in all supersymmetric string theories), (iii) new alpha'-exact result for central charges in AdS_3 X S^3 X S^3 X S^1 geometry. As a tool we used our generalization of Sen's entropy function formalism to AdS_p with p>2, and paid special attention to proper definition of asymptotic charges.

title: Essays on the impact of politicians' characteristics and speeches on policy outcomes
Creators: name: Mitra, Alessio
Publisher: name: University of Kent
Year: 2023

description: This thesis consists of three self-contained essays. The first substantive chapter, entitled "Should you want an educated mayor? Evidence from close elections in Italy", studies the impact of politicians' education on policy choices and public finance. A probabilistic voting model with candidates' education level and public expenditure decomposition is used to explain how a politician's education matters for policy decisions over public budget allocation. Empirically, I use Italian municipality data on electoral results, balance sheets, and mayor candidates' educational attainment from 2000 to 2015. To estimate the causal effect of mayors' education on public finance I rely on regression discontinuity design focusing on close elections. Overall, I find that educated mayors boost public investment, especially in the education sector, without compromising the fiscal stability of the municipalities. The second substantive chapter, entitled "The impact of women's political leadership on institutional quality", studies the impact of female political leadership on future women's participation in politics and hiring in public administration, as well as on different measurements of institutional quality. Empirically, I use Italian municipal and provincial data on elections, politicians, and institutional characteristics from 2000 to 2015. To estimate the causal effect of electing female mayors I rely on regression discontinuity design, and instrumental variable approach, focusing on close elections. Overall, I find that women's political leadership boosts women's participation as politicians and public servants while improving a wide set of institutional quality metrics, reducing corruption, increasing government effectiveness, the rule of law, and political accountability. Furthermore, the positive impact of female leadership on institution quality is stronger in areas with more established gender norms, and if the female politician is holding a tertiary education degree. The third substantive chapter, entitled "Do speeches at the UN General Assembly affect international aid allocation?", studies whether countries' speeches at the United Nations General Assembly matter for international aid allocation. I use a supervised machine learning algorithm called wordscore and 7,533 different statements from 198 countries made in the period from 1975 to 2018 to measure countries' preferences from text. I find considerable evidence that countries' preferences derived from speeches affect aid allocation. Both the US and Russia provide more aid to those countries whose speeches please their current agenda and preferences the most.

description: Centrotrachelus costatus m.
(C. asmussi Strauch. var. 9). (Hiezu Tai. X.)
Im 3ten Nachtrag zum Katalog habe ieh unter dem Namen Uromastix eostatus eine vermuthlich neue Agame beschrieben und dabei hervorgehoben, wie sehr bei derselben bei sonst grösster Aehnlichkeit mit dem Gesammthabitus eines Uromastix besonders die Beschaffenheit des Schwanzes von allen andern bekannten Arten dieser Gattung abweiohe. Bei meinen weitern Nachforschungen bin ich auf die „ Characteristik zweier neuen Eidechsen aus Persien “ von Strauch (Mélanges biologiques, IV) aufmerksam geworden. Herr Dr. Alex. Strauch in Petersburg hat die Güte gehabt, auf mein Ansuchen einige ihm zugesendete Skizzen mit dem Original in der Petersburger Sammlung zu vergleichen und mir Blanfords Zoology of Eastern Persia, welche unserer Bibliothek fehlt, zuıustellen. Hienach kann kein Zweifel sein, dass unser Uromastix costatus der Gattung Centrotrachelus angehört. Dagegen erscheint es noch ııngewiss, ob auch die Art dieselhe sei. Die Unterschiede sind folgende:
1. Beim Basler Exemplar sind alle Schwanzstacbeln nach hinten und un ten gebogen, während die Abbildung bei Blanford deutlich eine Abbiegung nach hinten und oben zeigt.
2. Die rippenartigen Reihen der grössern Rückenschuppen sind bei dem Basler Exemplar lange nicht so stark ausgeprägt und dicht stehend, wie die Blanforıfsche Abbildung dies aufweist.
3. Strauch und Blanford geben für C. asmussi jederseits 9 bis 11 Schenkelporen an, welche sich nicht über die Praeanalregion erstrecken; das Basler Exemplar besitzt jederseits 17 Poren, welche über dem After in einem stumpfwinkligen, mit der Spitze nach hinten gerichteten Bogen zusammenstossen.
4. C. asmnssi hat, abgesehen von dem medianen, blos aus Knoehensubstanz bestehenden Schneidezahn (cutting edge von Blanford), jederseíts im Oberkiefer 22, im Unterkiefer 20 Zähne; das Basler Stück oben und unten je 19.
Unsere Zeichnung gibt genau die abweichenden Verhältnisse der Rückeubeschuppung und der Schwauzstachelu. Wenn die Blauford'sche Abbildung correct ist, so werden die unter 1 —4 aufgeführten Unterschiede zusammengenommen wahrscheinlich zur Aufstellung einer neuen Art berechtigen, insofern man sie nicht aus der Verschiedeuheit der Gescblechter herleiteu will (unser Exemplar ist ♀). Dis Vermehrung der Schenkelporen bei ♀ wäre aber eine auffallende Suche.

description: A saponin (1) with gypsogenin as aglycone was isolated from the roots of Pulsatilla cernua. The aglycone of compound 1 was considered as gypsogenin which was rarely found in this genus. Its structure was predicted by NMR-based “mosaic” method rapidly, and further confirmed on the basis of spectroscopic data, including 2D NMR spectra and chemical evidence. This work suggested that NMR-based mosaic method is suitable for most of saponins from common species of genus Pulsatilla.

description: 62 donors aged from 20 to 55 years (33 men and 29 women) were examined. Among them, 29 people (17 men and 12 women) donated for the first time in their lives - they made up the first (I) observation group, and 33 donors (17 men and 16 women) were regular donors with a donation experience of more than two years and did not less than two donations annually—they formed the second (II) observation group. The article presents the results of a study of the morphological characteristics of erythrocytes in active blood donors and some parameters that characterize the physical properties of erythrocytes. It was concluded that active donation may be accompanied by changes in a number of morphological and physical characteristics of red blood cells.

description: Das Psalter-Stundenbuch der Ghuiluys de Boisleux und des Jean de Neuville, welches in die Dekade 1240 datiert wird und vermutlich in der Stadt Arras oder ihrer näheren Umgebung angefertigt wurde, visualisiert mit seinen Randilluminationen eine Aufbruchsstimmung der gotischen Randdarstellungen, welche durch innovative Lösungen in der Beziehung einer Figur zu dem Rankenornament sowie der Wahl der Motive artikuliert wird. Zu Beginn des 13. Jahrhunderts war das Ausbrechen vegetabiler Elemente der Initiale auf den Rand zu konstatieren, die immer weiter auf den Rand ausgriffen und diesen eroberten, wodurch die Beziehung zwischen der Figur und der Ranke nachhaltig beeinflusst wurde, da ein spannungsreiches Verhältnis einer symbiotischen Beziehung wich. Mit der Benützung einer Ranke als Bühne gelangte die Emanzipation zu einem vorläufigen Ende. Das PsalterStundenbuch zeichnet mehrere Darstellungsmodi bei dem Verhältnis von Figur und Rankenornament aus und die Signifikanz liegt in einer neuen Interpretation der symbiotischen Beziehung von Figur und Ranke, die bewusst agierende Figuren verdeutlicht, welche die Grenzen der Symbiose neu ausloten. Die Ausstattung des Psalter-Stundenbuchs, mit narrativen Szenen des Alten und Neuen Testaments, einem ausführlichen fortlaufenden Zyklus narrativer Szenen aus dem Leben Davids an den liturgischen Teilungsstellen sowie mit Randilluminationen, artikuliert anschaulich eine enorme Personalisierung für das Ehepaar Jean de Neuville und Ghuiluys de Boisleux, mit einer präzisen femininen Akzentuierung. Die Wiedergabe der Themen Kampf, Musik und Tanz sowie Turnier fußte einerseits auf tradierten Bildmotiven und brachte andererseits innovative Darstellungen vor, wobei inhaltliche Aussagen und Anspielungen einen interpretatorischen Spielraum gewähren. Witz und Humor spielen bei den Randilluminationen eine entscheidende, in die Zukunft weisende Rolle, obwohl das typisch freundliche Lächeln vieler Randfiguren bis jetzt in keinem weiteren Manuskript nachgewiesen wurde.

description: The kinetics of the self-assembly of nanocomponents into a virus, nanocapsule, or other composite structure is analyzed via a multiscale approach. The objective is to achieve predictability and to preserve key atomic-scale features that underlie the formation and stability of the composite structures. We start with an all-atom description, the Liouville equation, and the order parameters characterizing nanoscale features of the system. An equation of Smoluchowski type for the stochastic dynamics of the order parameters is derived from the Liouville equation via a multiscale perturbation technique. The self-assembly of composite structures from nanocomponents with internal atomic structure is analyzed and growth rates are derived. Applications include the assembly of a viral capsid from capsomers, a ribosome from its major subunits, and composite materials from fibers and nanoparticles. Our approach overcomes errors in other coarse-graining methods which neglect the influence of the nanoscale configuration on the atomistic fluctuations. We account for the effect of order parameters on the statistics of the atomistic fluctuations which contribute to the entropic and average forces driving order parameter evolution. This approach enables an efficient algorithm for computer simulation of self-assembly, whereas other methods severely limit the timestep due to the separation of diffusional and complexing characteristic times. Given that our approach does not require recalibration with each new application, it provides a way to estimate assembly rates and thereby facilitate the discovery of self-assembly pathways and kinetic dead-end structures.

Competing without parties : voter mobilization in Peru
Creators: name: Hurtado Lozada, Enilda Veronica Beatriz
Publisher: name: University of British Columbia
Year: 2024

description: Through an examination of the functioning of Peru’s precarious democracy, this dissertation presents four empirical studies on party system collapse, fragmented social mobilization and uneven state capacity. Using mixed methods of inquiry that include twenty-two in-depth interviews with political actors, three months of archival research, analysis of government data and an original survey experiment, the dissertation contributes to our understanding of the long-term consequences of the absence of political parties in democracy. Using a comparative case study approach focused on left-wing political initiatives, the first paper offers a theoretical rationale for the persistent lack of political parties in Peru. I argue that political parties operate as mere electoral vehicles that, despite their ambition to evolve into a political party, fail to coordinate long-term alliances with social organizations. As a result, the current state of Peruvian party politics is one of constant creation and dissolution of small electoral vehicles led by personalistic candidates with vague ideological and programmatic commitments. In the second paper, I turn to analyzing the consequences of the instability of Peru’s party system on voters’ evaluation of candidates during elections. Through an original survey experiment conducted during the 2021 presidential election, I show that candidates’ use of misinformation is not punished by voters, and argue that this lack of punishment is driven by voters’ normalization of incivility in the political arena. Finally, in the third and fourth paper, I explore how in the absence of strong parties, presidents use alternative avenues to build popularity and enact policy. Specifically, in the context of Covid-19 pandemic, I conduct two comparative studies that emphasize the importance of presidential leadership to enact stringent pandemic restrictions as a response to the uneven capacity of the state in the country. I show that the retributions these policies have on their public support are conditioned by political factors such as the timing of the policy, its framing and the power of the opposition.
scRNA-seq analysis of Gsx1 gene therapy reveals a restoration of the pre-injury spinal cord environment and reduction of inflammation
Creators: name: Dalmia, Mridul
Publisher: name: No Publisher Supplied
Year: 2023

description: Spinal cord injury (SCI) is a debilitating condition that affects 20 million individuals worldwide, causing a wide array of physical and behavioral deficits. Currently, no cure exists for SCI, with treatments focusing on inflammation control and decompression. One potential treatment strategy involves the promotion of neural stem/progenitor cells (NSPCs) for regeneration using gene therapies. Gsx1 is a candidate gene for these therapies, being implicated in embryonic neural development, particularly in the regulation of excitatory and inhibitory interneuron development. Lentiviral-mediated Gsx1 gene therapy has been shown to increase the number of NSPCs in the hemisection mouse model of SCI. Single-cell RNA-sequencing (scRNA-seq), however, has not yet been used to better understand the mechanisms by which Gsx1 acts as a therapeutic agent and the effects of the gene therapy at the single-cell resolution. In this study, scRNA-seq analysis reveals that the mouse spinal cord has distinct cell composition and populations after SCI and AAV-mediated Gsx1 gene therapy at 7 dpi in the contusion mouse model. The novel AAV-Gsx1 construct used to deliver the therapy preferentially targets the ependymal cell (EpC) population, and the effects of the therapy can also be seen in the oligodendrocyte progenitor cell (OPC), astrocyte, and microglia populations. Gsx1 gene therapy restores EpC and OPC subpopulation ratios to pre-injury levels, suggesting the presence of pre-SCI signaling and environment. Additionally, Gsx1 gene therapy reduces the neuroinflammatory subpopulations of EpCs and astrocytes, while retaining a similar proportion in microglia, indicating both safety of the AAV-Gsx1 construct, as well as the anti-inflammatory properties of the therapy. The reduction of neuroinflammation and restoration of a pre-SCI environment can account for previously observed glial scar attenuation and functional recovery with Gsx1 gene therapy. Collectively, this study provides mechanistic insights into AAV-mediated Gsx1 gene therapy for SCI, allowing for the refinement and further development of the therapy that targets the relevant cell populations and pathways identified via this scRNA-seq analysis.
Combination of EUROMOD and LIAM2 tools for the development of dynamic microsimulation models, Feasibility, example and conditions for sustainability of the linkage
Creators: name: Liégeois, Philippe
Publisher: name: Zenodo
Year: 2021

description: LISER has implemented, within Work Package 8 of the EU-’HORIZON 2020’-funded ‘InGRID-2’project (http://www.inclusivegrowth.eu/), a combination of tools for the development of dynamic microsimulation models which objective is ‘to establish a linkage between two important microsimulation platforms: EUROMOD and LIAM2’.EUROMOD is an efficient and well-known platform for the development of static microsimulation models. It is also a model in itself. LIAM2 is a free, open source and user-friendly modelling and simulation framework, mainly implemented for the development of dynamic discrete-time microsimulation models with cross-sectional population ageing. LIAM2 has strong similarities in its built-in logic and grammar to EUROMOD. It is not a model but has been adopted by modellers in at least nine countries (AR, BE, CN, FR, IT, HU, LU, PT and SK) and has led to the creation of several dynamic microsimulation models with a similar structure (based on MiDAS_BE, Federal Planning Bureau, Brussels).In examining the possible avenues for implementing a link between the two platforms, one track was favoured, known as ‘Dynamic in Static/DiS’. It aims at dynamising to a certain extent a static model such as EUROMOD in order to carry out short-term projections, as is already done in the well-known developments of ‘nowcasting’. But our aim is to derive a device that is both as transparent as possible, and therefore more easily reproducible and improvable, and that links EUROMOD to another innovative development platform targeting the development and simulation of dynamic models. This could open up avenues for a more sophisticated implementation of the dynamic side of the combination, which might be valuable in a particularly volatile context. This implementation may also generate positive by-products of interest for the development of dynamic microsimulation models in a broader sense. This includes a ‘Static in Dynamic/SiD’ approach in which EUROMOD could become the tax-benefit module of a larger dynamic model operating over the long term. While proceeding, we emphasise the ‘infrastructural’ nature of the InGRID-2 project, hence the need to draw synergies from existing experiences to innovate at the level of the development and simulation tools mobilised in the background (EUROMOD-LIAM2 linkage), more than to rewrite from scratch or on a large scale, or even to deepen, the short-term projection procedures. What is at stake here is a method, considered as an intermediate good, rather than applications, considered as final goods, yet keeping in mind that the latter remain of utmost importance with regard to the sustainability of the path proposed here. The methodology of combination is described, implemented and first outcomes reported, including possible drawbacks.

We report the first laser cooling and trapping of half a billion Dy atoms using a repumper-free magneto-optical trap (MOT) and continuously loaded magnetic confinement, and we characterize the trap recycling dynamics for bosonic and fermionic isotopes. The first inelastic collision measurements in the few partial wave, 100 uK to 1 mK, regime are made in a system possessing a submerged open electronic f-shell. In addition, we observe unusual stripes of intra-MOT <10 uK sub-Doppler cooled atoms.

This hot electron technique, which requires no micron-scale patterning of the 2DES, is much less sensitive than conventional methods to phonon-drag effects. Our thermopower results are in good agreement with the Mott formula for diffusion thermopower for temperatures up to T ~ 2 K.

Toral rank conjecture for moment-angle complexes

Publisher: name: arXiv
Year: 2009
Subjects: subject: Algebraic Topology (math.AT)
subject: FOS: Mathematics

description: We consider an operation K \to L(K) on the set of simplicial complexes, which we call the "doubling operation". This combinatorial operation has been recently brought into toric topology by the work of Bahri, Bendersky, Cohen and Gitler on generalised moment-angle complexes (also known as K-powers). The crucial property of the doubling operation is that the moment-angle complex Z_K can be identified with the real moment-angle complex RZ_L(K) for the double L(K). As an application we prove the toral rank conjecture for Z_K by estimating the lower bound of the cohomology rank (with rational coefficients) of real moment-angle complexes RZ_K$. This paper extends the results of our previous work, where the doubling operation for polytopes was used to prove the toral rank conjecture for moment-angle manifolds.

Negotiating gender in crisis : global norms and state power in South Sudan
Creators: name: Luedke, Alicia Elaine
Publisher: name: University of British Columbia
Year: 2024

description: Ever since the 1990s and 2000s, the aid architecture in conflict-affected states frequently contains elements related to the promotion of gender equality and the elimination of gender-based violence (GBV), usually under the broader rubric of the gender mainstreaming and Women, Peace, and Security (WPS) agendas. While this has contributed to successes in ensuring that domestic discourse and policy reflect women’s rights and protections, seldom does the formalization of gender equality and the elimination of GBV translate into real improvements. Utilizing the granular details of the everyday politics of customary chiefs’ courts, the mobilization of community-embedded armed groups and the organization of urban gangs in South Sudan, this dissertation shows how international norms related to gender equality and violence get caught up in the contestation over the limits and extent of state power. It unfolds in two key ways. First, it shows how gendered inequality and violence, including conflict-related sexual violence are, in part, a function of the complex confluence of the cooptation by, and resistance to, different forms of state power over the course of the 20th century in South Sudan. Second, it shows how policy responses have tended to treat state and non-state actors as mutually exclusive, failing to recognize the contestation taking place over how authority will be configured in ways that have limited the purchase and reach of international norms. The argument and the empirical details that this dissertation relies on provide important insight into the factors that condition the movement from commitment to compliance in target states by showing how the norms that external actors promote get caught up in the very gendered ways that local politics unfolds, mediating the influence of international efforts. In so doing, it demonstrates the significance of destabilizing more conventional distinctions employed in both social constructivism and policy responses that have mostly interrogated compliance by either state or non-state actors, rather than looking at their interaction and the fluid lines between them as essential to both the understanding and resolution of compliance problems.

description: Exciton bandwidths and exciton transport are difficult to control by material design. We showcase the intriguing excitonic properties in an organic semiconductor material with specifically tailored functional groups, in which extremely broad exciton bands in the near-infrared-visible part of the electromagnetic spectrum are observed by electron energy loss spectroscopy and theoretically explained by a close contact between tightly packing molecules and by their strong interactions. This is induced by the donor–acceptor type molecular structure and its resulting crystal packing, which induces a remarkable anisotropy that should lead to a strongly directed transport of excitons. The observations and detailed understanding of the results yield blueprints for the design of molecular structures in which similar molecular features might be used to further explore the tunability of excitonic bands and pave a way for organic materials with strongly enhanced transport and built-in control of the propagation direction.
Behavior of Li abundances in solar-analog stars II. Evidence of the connection with rotation and stellar activity

description: We previously attempted to ascertain why the Li I 6708 line-strengths of Sun-like stars differ so significantly despite the superficial similarities of stellar parameters. We carried out a comprehensive analysis of 118 solar analogs and reported that a close connection exists between the Li abundance A_Li and the line-broadening width (v_r+m; mainly contributed by rotational effect), which led us to conclude that stellar rotation may be the primary control of the surface Li content. To examine our claim in more detail, we study whether the degree of stellar activity exhibits a similar correlation with the Li abundance, which is expected because of the widely believed close connection between rotation and activity. We measured the residual flux at the line center of the strong Ca II 8542 line, r_0(8542), known to be a useful index of stellar activity, for all sample stars using newly acquired spectra in this near-IR region. The projected rotational velocity (v_e sin i) was estimated by subtracting the macroturbulence contribution from v_r+m that we had already established. A remarkable (positive) correlation was found in the A_Li versus (vs.) r_0(8542) diagram as well as in both the r_0(8542) vs. v_e sin i and A_Li vs. v_e sin i diagrams, as had been expected. With the confirmation of rotation-dependent stellar activity, this clearly shows that the surface Li abundances of these solar analogs progressively decrease as the rotation rate decreases. Given this observational evidence, we conclude that the depletion of surface Li in solar-type stars, probably caused by effective envelope mixing, operates more efficiently as stellar rotation decelerates. It may be promising to attribute the low-Li tendency of planet-host G dwarfs to their different nature in the stellar angular momentum.

description: Millisecond and binary pulsars are the most stable astronomical standards of frequency. They can be applied to solving a number of problems in astronomy and time-keeping metrology including the search for a stochastic gravitational wave background in the early universe, testing general relativity, and establishing a new time-scale. The full exploration of pulsar properties requires that proper unbiased estimates of spin and orbital parameters of the pulsar be obtained. These estimates depend essentially on the random noise components present in pulsar timing residuals. The instrumental white noise has predictable statistical properties and makes no harm for interpretation of timing observations, while the astrophysical/geophysical low-frequency noise corrupts them, thus, reducing the quality of tests of general relativity and decreasing the stability of the pulsar time scale.

description: Background: The Lactobacillus family comprises many species of great importance for the food and healthcare industries, with numerous strains identified as beneficial for humans and used as probiotics. Hence, there is a growing interest in engineering these probiotic bacteria as live biotherapeutics for animals and humans. However, the genetic parts needed to regulate gene expression in these bacteria remain limited compared to model bacteria like E. coli or B. subtilis. To address this deficit, in this study, we selected and tested several bacteriophage-derived genetic parts with the potential to regulate transcription in lactobacilli. Results: We screened genetic parts from 6 different lactobacilli-infecting phages and identified one promoter/repressor system with unprecedented functionality in L. plantarum WCFS1. The phage-derived promoter was found to achieve expression levels nearly 9-fold higher than the previously reported strongest promoter in this strain and the repressor was able to almost completely repress this expression by reducing it nearly 500-fold. Conclusions: The new parts and insights gained from their engineering will enhance the genetic programmability of lactobacilli for healthcare and industrial applications. Competing Interest Statement: A patent application has been filed based on the results of this work (Application no. is DE 102022 119024.2).

description: Background and Purpose - NMDA receptor subunit composition strictly commands receptor function and pharmacological responses. The identity of the GluN2 subunit regulates biophysical and pharmacological properties of the receptor and influences receptor assembly, signaling and trafficking to the postsynaptic membrane. The number or subunit composition of NMDA receptors vary during activity dependent plasticity and CNS disorders like Parkinson's disease (PD) and L-DOPA-induced dyskinesia (LID) where you can find an enhanced extrasynaptic localization of GluN2B-containing NMDA receptors and an increase of the GluN2A/GluN2B ratio at striatal synapses. Recently, a two-hybrid screening to find potential proteins interacting with the C-terminal tail of the GluN2A subunit of the NMDA receptor has highlighted Rabphilin 3A (Rph3A) as a potential partner. Rph3A is a synaptic vesicle-associated protein that was first identified as a binding partner of the GTP-bound Rab3A, a member of the Rab family of GTPases implicated in vesicle docking/fusion reactions. Moreover, different studies have indicated that Rph3A can regulate exo- and endocytosis processes at synaptic sites. Our goal was to characterize Rph3A interaction with GluN2A at postynaptic sites and to assess its relevance in PD and LID. Methods and Results - Firstly, we verified its interaction with GluN2A by immunoprecipitation and GST pull-down experiments. Subcellular fractionation assays revealed that Rph3A is present in Triton Insoluble Postsynaptic compartment and post-synaptic density (PSD) fractions. Immunofluorescence studies performed in neuronal hippocampal cultures, confirmed biochemical experiments revealing Rph3A colocalization with PSD-95 (marker of the postsynaptic compartment) and GluN2A. Moreover, we found Rph3A to be interacting with a 40AA domain on C-terminal tail of GluN2A between AA 1349 and 1389. Therefore, we designed a cell permeable peptide containing this sequence called TAT-2A-40. This peptide is capable of disrupting the interaction between Rph3A and GluN2A. By doing this, it can reduce the expression of GluN2A in dendritic spines and its surface expression as we show by immunocytochemistry and electrophysiology. Moreover, we have observed an increase of GluN2A/Rph3A interaction in a rat PD model as well as a rat LID model. We have that the TAT-2A-40 was capable of significantly reducing the dyskinetic behavior in these animals. Conclusions - These results strongly indicate the presence of Rph3A in the PSD compartment and suggest a function of Rph3A in the modulation of NR2A localization. Rph3A could play a crucial role in the stabilization of GluN2A subunits at the plasma membrane in dendritic spines. Therefore, this interaction could be a potential therapeutic target for diseases where NMDAR composition is significantly altered such as Parkinson's Disease and L-DOPA-induced dyskinesia.
The dizziness of recognition : exile as an educative engagement

description: The state of exile can send individuals to carry a sense of perpetual separation within, its intricacies concealed. This dissertation discusses the notion of exilic subjectivity, a hidden facet of the self ineffable to both the Other or oneself, causing a distance between self-comprehension and external perception. When certain experiences defy complete understanding, such particularities may seldom surface, serving as a monologue to oneself. This poses a challenge to the theory of recognition, positing that self-understanding is achieved through dialogue and encounters involving Others. Recognizing and understanding one’s particularities may be a difficult task, compounded by the interplay of the self’s fixed, hidden, and becoming particularities. The following embarks on an exploration of exile from a subject-oriented point of view, emphasizing the transformative effects of such migratory subjectivity and its implications for recognition theory. It engages with interlocutors like Georg Wilhelm Friedrich Hegel, Charles Taylor, and Axel Honneth, who highlight recognition’s ethical and political dimensions concerning exilic subjectivity. In addition, it examines the writings of contemplative thinkers like Søren Kierkegaard and poet Rumi, who raise questions about recognition beyond dialogic frameworks by speaking to the silences placed within the self. Through a phenomenological lens, the text investigates “seeing” the Other and the potential for misrecognition of an individual’s innermost depths. These insights find resonance in the classroom setting, where even amid academic success and collaborative learning, a chasm may persist, isolating students from each other. As the self dwells in the uneasiness of estrangement, the discussion explores the value in bringing the ownership of silence and inwardness into the classroom. Dissecting a reliance on vision, the following suggests that educators may also prioritize attentive listening to students’ diverse needs and experiences. It argues for a sensitivity that fosters self-reflection, creating a climate where subjectivities of exile serve as bridges to community. By turning inward, individuals may craft a sanctuary within, transforming the pain of exile into a source of solace. This process nurtures a detached perspective, enabling the possibility of recognizing the convergence of familiarity and strangeness before and within oneself.

description: Nanostructured earth abundant metal catalysts that mediate important chemical reactions with high efficiency and selectivity are of great interest. This study introduces a synthesis protocol for nanostructured earth abundant metal catalysts. Three components, an inexpensive metal precursor, an easy to synthesize N/C precursor, and a porous support material undergo pyrolysis to give the catalyst material in a simple, single synthesis step. By applying this catalyst synthesis, a highly active cobalt catalyst for the general and selective hydrogenation of aromatic heterocycles could be generated. The reaction is important with regard to organic synthesis and hydrogen storage. The mild reaction conditions observed for quinolines permit the selective hydrogenation of numerous classes of N-, O- and S-heterocyclic compounds such as: quinoxalines, pyridines, pyrroles, indoles, isoquinoline, aciridine amine, phenanthroline, benzofuranes, and benzothiophenes.
NUCLEATION PROCESSES IN HIGH-RELIEF CARBONATE PLATFORMS: SEDIMENTOLOGIC CHARACTERIZATION, FACIES COMPOSITION AND DEPOSITIONAL EVOLUTION OF THE ESINO LIMESTONE (LADINIAN-LOWER CARNIAN) IN LOMBARDY

description: High-relief carbonate platforms evolve from a poorly known nucleation stage that has different environmental conditions and depositional processes with respect to the mature stage of the platform. To understand the processes that lead to the development of a high-relief carbonate platform, it is crucial to analyze facies type and distribution during the early phase of their development. The Esino Limestone (up to 800m thick, with a final platform-to-basin relief of 550 m) preserves exposed the inception stage deposits. In its mature configuration the carbonate system was characterized by a wide inner platform (bedded peritidal limestones with stromatolites, oncoids, fenestrae and dasycladaceans), bordered by a narrow reef (Tubiphytes and microbial mounds associated with coral framestones with calcisponges and intrabioclastic packstone) that sourced the breccias of the steep slopes. 20 stratigraphic sections have been measured and about 600 samples for microfacies analysis have been collected in the 30-130 meters-thick succession of the nucleation stage. Facies type and distribution led to the stratigraphic reconstruction and to the identification of major phases in the early platform evolution, which are linked with relative sea-level changes. A first transgression, following the drowning of the antecedent peritidal platform (Camorelli Limestone), is characterized by the deposition of dark bioturbated bio-intraclastic packstone and wackestone passing to bedded black marly limestones and marls (Prezzo Limestone). A general regressive trend is characterized by intraclastic packstones and decreased terrigenous input. Sparse reefal bafflestones (porifera, algae, corals, Tubiphytes) and peritidal facies (stromatolitic bindstone with fenestrae, early marine cements, intrabioclastic packstone) record the final onset of the core of the future high relief carbonate platform. The end of the inception stage is thus controlled by the progradation of sparse patch reefs that fill up the depositional space, leading to the coalescence of isolated small nuclei of carbonate production. This study documented the key role played by antecedent topography and sea-level changes in the localization and growth of the first platform nuclei. Furthermore, environmental conditions (e.g. terrigenous input, water circulation) possibly exerted a control on the organisms? associations that characterized the first stages of platform evolution.

description: We give a survey and unified treatment of functional integral representations for both simple random walk and some self-avoiding walk models, including models with strict self-avoidance, with weak self-avoidance, and a model of walks and loops. Our representation for the strictly self-avoiding walk is new. The representations have recently been used as the point of departure for rigorous renormalization group analyses of self-avoiding walk models in dimension 4. For the models without loops, the integral representations involve fermions, and we also provide an introduction to fermionic integrals. The fermionic integrals are in terms of anti-commuting Grassmann variables, which can be conveniently interpreted as differential forms.
