description: We generalise the Clark-Ocone formula for functions to give analogous representations for differential forms on the classical Wiener space. Such formulae provide explicit expressions for closed and co-closed differential forms and, as a by-product, a new proof of the triviality of the L^2 de Rham cohomology groups on the Wiener space, alternative to Shigekawa's approach [16] and the chaos-theoretic version [18]. This new approach has the potential of carrying over to curved path spaces, as indicated by the vanishing result for harmonic one-forms in [6]. For the flat path group, the generalised Clark-Ocone formulae can be proved directly using the Itô map.

description: This paper presents a new homogeneity measure for variational segmentation with multiple level set functions. We propose to modify the quadratic homogeneity measure to trade off the convexity of the function against a faster rate of convergence. We tested in two series of experiments the performance of this new homogeneity force at converging to appropriate partitioning of brain MRI data sets, over a large range of image spatial resolution and image quality, in terms of tissue homogeneity and contrast.

description: We construct RG flow solutions interpolating AdS and Schrodinger geometries in Abelian Higgs models obtained from consistent reductions of type IIB supergravity and M-theory. We find that z=2 Schrodinger geometries can be realized at the minima of scalar potentials of these models, where a scalar charged under U(1) gauge symmetry obtains a nonzero vacuum expectation value. The RG flows are induced by an operator deformation of the dual CFT. The flows are captured by fake superpotentials of the theories.

description: Along with a renewed interest in the use of pattern and ornament in architecture, there is a growing body of research into how cognitive processes shape the experience of the built environment and an increasing awareness that embodied experiences of making can deepen the level of critical engagement with concepts related to technology and society. The intersection between the fields of design and production of architectural ornament and the study of the perception and experience of the built environment provides a rich territory for design research and innovation. Digital tools and processes such as robotic fabrication have added a range of new possibilities in terms of precision, dexterity and human/machine collaboration in bringing digital design into physical space. These tools and processes offer the potential to democratize the design and production of the built environment.

description: We apply a rigorous eigenmode analysis to study the electromagnetic properties of linear and weakly nonlinear metamaterials. The nonlinear response can be totally described by the linear eigenmodes when weak nonlinearities are attributed to metamaterials. We use this theory to interpret intrinsic second-harmonic spectroscopy on metallic metamaterials. Our study indicates that metamaterial eigenmodes play a critical role in optimizing a nonlinear metamaterial response to the extent that a poorly optimized modal pattern overwhelms the widely recognized benefits of plasmonic resonant field enhancements.

description: We provide new upper bounds on N_q(g), the maximum number of rational points on a smooth absolutely irreducible genus-g curve over F_q, for many values of q and g. Among other results, we find that N_4(7) = 21 and N_8(5) = 29, and we show that a genus-12 curve over F_2 having 15 rational points must have characteristic polynomial of Frobenius equal to one of three explicitly given possibilities. We also provide sharp upper bounds for the lengths of the shortest vectors in Hermitian lattices of small rank and determinant over the maximal orders of small imaginary quadratic fields of class number 1. Some of our intermediate results can be interpreted in terms of Mordell-Weil lattices of constant elliptic curves over one-dimensional function fields over finite fields. Using the Birch and Swinnerton-Dyer conjecture for such elliptic curves, we deduce lower bounds on the orders of certain Shafarevich-Tate groups.

description: This year the Baseball Writer's Association of America (BBWAA) failed to elect anybody to the Baseball Hall of Fame. This was partially because all time greats such as Barry Bonds and Roger Clemens were linked to steroid use, while other strong candidates like Jeff Bagwell and Mike Piazza were, fairly or not, rumored to have used steroids, too. The steroid issue, however, only partially explains why nobody was elected to the Hall of Fame. The other major reason is that the voting system used by the BBWAA is flawed.

description: The non-obese diabetic (NOD) mouse is commonly used for studying type-1 diabetes (T1D). Among many β-cell auto-antigens (Ags), the Santamaria lab has focused on understanding the role of the islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP) in T1D pathogenesis. In NOD mice, a highly-diabetogenic CD8+ T-cell population recognizing a H-2K-restricted IGRP206-214 epitope is found in the islets of pancreas. The deletional tolerance of these cells occurs independently of IGRP206-214/Kd recognition, particularly in the post-neonatal period when commensals actively colonize the gut. Hence, the first part of this thesis focused on identifying microbial epitope(s) similar to IGRP206-214 and determining the biological importance of such recognition in NOD mice and humans. Our findings suggested that an integrase protein expressed by several species of the genus Bacteroides contains a mimic for auto-Ag pancreatic -cell IGRP (residues 206-214; IGRP206-214). Bacteroides integrase promoted the recruitment of diabetogenic high-avidity IGRP206-214-specific 17.4-CD8+ T-cells into the gut and suppressed experimental colitis by targeting BacIYL36-44-presenting gut microbial Ag-loaded Ag-presenting cells (APCs). This suggests that Bacteroides integrase is a beneficial Ag for the host in suppressing colitis and that the suppression of pro-inflammatory APCs is beneficial in controlling inflammation in the gut. The Santamaria lab has shown that administration of disease-relevant peptide/major histocompatibility complex (pMHC II)-coated NPs in mice suppressed three different autoimmune diseases—T1D, experimental autoimmune encephalomyelitis (EAE: a model of MS) and experimental arthritis—without affecting systemic immunity, which resulted from the induction/expansion of disease-relevant Tr1-like CD4+ T-cells. The suppression of autoimmunity was mainly mediated by IL-10 and TGF- secretion by Tr1-like cells. By considering the importance of Tregs in the suppression of inflammatory bowel disease (IBD), In the second part of my thesis work, we developed pMHC II nanomedicines displaying peptides from prevalent gut microbial Ags (Bacteroides integrase, flagellin, Yidx and Fla-2) and tested their efficacy in murine models of colitis. We found that gut microbial Ag-relevant pMHC II-NPs induced/expanded cognate Tr1-like CD4+T-cells, resulting in the suppression of DSS-induced and T-cell transfer models of colitis without compromising mucosal immune response. The suppressive capacity of Tr1-like cells was mainly mediated by the secretion of IL-10 and TGF1 in the susceptible hosts.

description: We study the onset of particle statistics effects as the temperature is lowered in strongly correlated two-dimensional Hubbard models. We utilize numerical linked-cluster expansions and focus on the properties of interacting lattice fermions and two-component hard-core bosons. In the weak-coupling regime, where the ground state of the bosonic system is a superfluid, the thermodynamic properties of the two systems at half filling exhibit very large differences even at high temperatures. In the strong-coupling regime, where the low-temperature behavior is governed by a Mott insulator for either particle statistics, the agreement between the thermodynamic properties of both systems extends to regions where the antiferromagnetic (iso)spin correlations are exponentially large. We analyze how particle statistics affects adiabatic cooling in those systems.

description: Segmentation of three-dimensional anatomical brain images into tissue classes has applications in both clinical and research settings. This paper presents the implementation and quantitative evaluation of a four-phase three-dimensional active contour implemented with a level set framework for automated segmentation of brain MRIs. The segmentation algorithm performs an optimal partitioning of three-dimensional data based on homogeneity measures that naturally evolves to the extraction of different tissue types in the brain. Random seed initialization was used to speed up numerical computation and avoid the need for a priori information. This random initialization ensures robustness of the method to variation of user expertise, biased a priori information and errors in input information that could be influenced by variations in image quality. Experimentation on three MRI brain data sets showed that an optimal partitioning successfully labeled regions that accurately identified white matter, gray matter and cerebrospinal fluid in the ventricles. Quantitative evaluation of the segmentation was performed with comparison to manually labeled data and computed false positive and false negative assignments of voxels for the three organs. We report high accuracy for the two comparison cases. These results demonstrate the efficiency and flexibility of this segmentation framework to perform the challenging task of automatically extracting brain tissue volume contours.
The Appropriation of Abū Ḥāmid al-Ghazālī’s Ihyā’ ʿUlūm al-Dīn by the Sāda Bā ʿAlawī of Ḥaḍramawt

description: The Appropriation of Abū Ḥāmid al-Ghazālī’s Ihyā’ ʿUlūm al-Dīn by the Sāda Bā ʿAlawī of Ḥaḍramawt John F. Rhodus Jr. This dissertation examines the appropriation of Abū Ḥāmid al-Ghazālī’s Ịḥyā’ ʿUlūm al-Dīn by the Sāda Bā ʿAlawī of Hadramawt. The study begins by discussing the origins of the Sāda Bā ʿAlawī, highlighting the three most salient landmarks of their historical narrative and emphasizing what formed the backdrop of their appropriation of the Iḥyā’. I then proceed to introduce Abū Ḥāmid al-Ghazālī’s Ịḥyā’ ʿUlūm al-Dīn. I argue that it must be understood as intertwined with al-Ghazālī’s life and viewed through the lens of tajdīd (religious renewal), the essence of which is encased in his unique conception of ʿilm ṭarīq al-ākhira (The Science of the Path of the Hereafter). Once these foundational aspects of the study are in place, the thesis moves on to examine the convergence between the Sāda Bā ʿAlawī and the Ịḥyā’ ʿUlūm al-Dīn by exploring the silsila (initiatic chain) of the Sāda Bā ʿAlawī to al-Ghazālī’s magnum opus, the potential date of its arrival in Hadramawt, and the time period for the first stage of its appropriation. I argue that the process of appropriation began roughly around the time of Shaykh ʿAbd al-Raḥmān al-Saqqāf (d. 819/1416) and culminated in Shaykh ʿAbd Allah al-ʿAydarūs’s (d. 865/1461) project of promulgation, which was motivated by his position as Naqīb (Headman), the increased social distinction of the Sāda Bā ‘Alawī, new political developments in Hadramawt, and the burgeoning of the Bā ʿAlawī diaspora. Analyzing the hermeneutics of Shaykh ʿAbd Allah indicates that he saw the Iḥyā’ as both the best summary of the Bā ʿAlawī approach to religion as well as the preeminent practical manual for the path to God. He would then go on to dedicate himself to the promulgation of the Iḥyā’ with all means available to him to ensure its transmission to subsequent generations, thus establishing it as a core component of the Bā ʿAlawī tradition. At the nexus of Yemeni Sufism and Ghazālian studies, this study will uncover important dimensions of the understudied Sāda Bā ʿAlawī by examining them through the lens of al-Ghazālī’s Iḥya’ ʿUlūm al-Dīn and simultaneously demonstrating a positive reception of one of Islam’s most important works.

Enhancing corticospinal tract neurite outgrowth using histone deacetylase inhibitors
Creators: name: McShane, Christie
Publisher: name: University of British Columbia
Year: 2011

description: The human corticospinal tract (CST) is responsible for coordinated voluntary movement and it contains descending afferent inputs involved in autonomic control and gating of spinal reflexes. After spinal cord injury (SCI), damage to the CST causes degeneration of axons and can result in major motor impairments. The CST is especially lacking in its capacity to regenerate after injury. In the current study, we harvested the cortices of postnatal day 8 Thy1YFP16JRS mice, which express YFP in layer five projection neurons, which also express CST transcription factors Ctip2 and Otx1 in vitro. We applied Histone deacetylase (HDAC) inhibitors (Trichostain A [TSA] and Tubastatin A) to the mixed neuron culture and assessed survival and neurite outgrowth of YFP positive CST neurons. TSA treatment increased the number of primary neurites per neuron and the number of branch points exhibited by YFP positive CST neurons. Application of either TSA or Tubastatin A, promoted YFP positive CST neurite outgrowth in baseline media as well as in the presence of the neurotrophin 3 (NT3) and cilliary neurotrophic factor (CNTF), compared to the appropriate controls. Taken together, the application of HDAC inhibitors to postnatal corticospinal neurons can promote neurite outgrowth, branching and an increase in the number of primary neurites when grown in baseline media.

description: Most of the discussion regarding the Higgs boson couplings to Standard Model vector bosons and fermions is presented with respect to what present and future collider detectors will be able to measure. Here, we ask the more physics-based question of how well do we need to measure the Higgs boson couplings? We first present a reasonable definition of "need" and then investigate the answer in the context of various highly motivated new physics scenarios: supersymmetry, mixed-in hidden sector Higgs bosons, and a composite Higgs boson. We find the largest coupling deviations away from the SM Higgs couplings that are possible if no other state related to EWSB is directly accessible at the LHC. Depending on the physics scenario under consideration, we find targets that range from less than 1% to 10% for vector bosons, and from a few percent to tens of percent for couplings to fermions.

title: Rules of origin in North-South preferential trade agreements
Creators: name: Angeli, Marietta
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: The study of North-South trade agreements, their policy design and the negotiations that shape them, contains a knowledge gap on Rules of Origin (ROO). ROO regulate which goods get to benefit from preferential market access and prevent tariff fraud. In their simplest form, ROO are domestic content requirements but have mushroomed to create thousands of complex hurdles to preferential trade. This thesis fills this knowledge gap. The introduction contextualises the role of ROO in North-South trade agreements. Chapter 1 presents a comprehensive dataset on ROO design across trade agreements, the first of its kind, responding to a call for better public data on ROO issues from academics and policy makers alike. Chapter 2 applies this data to advance the debate around negotiation outcomes in North-South PTAs. The chapter applies novel metrics to show that the transition from GSP to PTA can lead to significant changes in the usability of trade preferences, but that these changes differ depending on the GSP donor and sector. These findings evidence that, in contrast to common characterisations in the literature, ROO are far from a blanket market access barrier. Instead, ROO design changes depending on who is negotiating what. The third chapter contributes to the discussion of possible drivers of negotiation outcomes, using primary and secondary evidence to better understand the actors and interests that influence ROO design and its variation. The findings suggest that ROO can be negotiated to achieve a variety of policy objectives beyond preventing tariff fraud, and second, that their complexity can often hamper their effective negotiation. Chapter 4 concludes with a look ahead on future research questions and policy conclusions.

description: This report investigates the evolving landscape of migration narratives in Germany, focusing on three pivotal events: the 'migration crisis' of 2015, the humanitarian catastrophe at the refugee camp 'Moria' in 2020, and the acceptance of Ukrainian refugees in 2022. Employing a multi-dimensional approach, the research scrutinizes narratives across media, political debate, and policy-making in terms of their key elements (characters, setting, plot and moral) as well as their style (lay vs. technocratic). Analysis of the textual data from these spheres is supplemented by insights gained through expert interviews with civil servants working in migration-related areas.
Against the backdrop of Germany's history of migration and migration policy, the report notes changing patterns in German public attitudes towards migration, characterized by shifts from positive perceptions tied to economic needs, to negative sentiments during the 2015 crisis, and a subsequent return to a more welcoming, economics-linked attitude in 2022, which is now challenged by a resurgent far-right opposition. Notably, these shifts in public sentiment are not consistently mirrored in media narratives, which have maintained positive narratives, casting migrants as victims and Germany as a hero. The research identifies nuanced differences in narrative framing across the case studies, especially concerning the portrayal of villains and the depth of analysis of root causes.
Furthermore, the study delves into whether and how media narratives are embraced, adapted, ignored or rejected in political debates and policy-making. While political debates largely embrace media narratives, even retaining their lay style, policy-making exhibits a more varying relationship. The coordinative sphere shows a convergence with media narratives in certain cases, such as the 'migration crisis' of 2015, but also reveals divergence, particularly in the case of 'Moria' in 2020.
On a broader level, our research identifies variations in consensus and controversy between the communicative and coordinative spheres, with the 2015 and 2020 case studies demonstrating differing patterns. Additionally, the study highlights the distinct approaches of opposition and government parties in the coordinative sphere, emphasizing how opposition parties often extend lay-style narratives from the communicative sphere into policy-making.
In conclusion, this research offers valuable insights into the complex interplay of public sentiment, media discourse, political dynamics, and policy formulation in the context of migration narratives in Germany. The findings contribute to a deeper understanding of the intricate relationships between these spheres and how narratives might impact policy-makings processes in specific contexts.

description: Close to a spacelike singularity, pure gravity and supergravity in four to eleven spacetime dimensions admit a cosmological billiard description based on hyperbolic Kac-Moody groups. We investigate the quantum cosmological billiards of relativistic wavepackets towards the singularity, employing flat and hyperbolic space descriptions for the quantum billiards. We find that the strongly chaotic classical billiard motion of four-dimensional pure gravity corresponds to a spreading wavepacket subject to successive redshifts and tending to zero as the singularity is approached. We discuss the possible implications of these results in the context of singularity resolution and compare them with those of known semiclassical approaches. As an aside, we obtain exact solutions for the one-dimensional relativistic quantum billiards with moving walls.

A SHORT REVIEW ON SSRIs

Publisher: name: Zenodo
Year: 2023

description: Selective Serotonin Reuptake Inhibitors (SSRIs) represent a class of drugs primarily used in the treatment of various mental health disorders, notably depression, anxiety disorders and certain other psychiatric conditions. This article aims to elucidate the history, pharmacological profile, therapeutic efficacy, adverse effects, and clinical considerations associated with SSRIs. SSRIs operate by selectively inhibiting the reuptake of serotonin in the synaptic cleft, thereby enhancing serotonin neuro transmission. This mechanism is pivotal in regulating mood, emotions, and behaviour. Thoroughly considering this action, SSRIs are recognized for their efficacy in alleviating symptoms of depression and managing anxiety disorders. The drugs within this class commonly prescribed include fluoxetine, sertraline, paroxetine, citalopram, and escitalopram. Despite their therapeutic benefits, SSRIs are associated with a spectrum of side effects, including gastrointestinal disturbances, sexual dysfunction, weight changes, and rarely emergent suicidal ideation, especially in  individuals. Moreover, discontinuation of SSRIs may lead to withdrawal symptoms, To overcome this a gradual tapering regimen is performed under medical supervision. The clinical utility of SSRIs extends beyond psychiatric conditions, with emerging evidence suggesting their potential in treating conditions such as premature ejaculation, premenstrual dysphoric disorder, and certain pain syndromes. Individual variability in response to SSRIs underscores the importance of personalized medicine in prescribing these medications. Factors such as genetic predisposition, co-existing medical conditions, concomitant drug use, and patient-specific considerations significantly influence treatment outcomes.

description: Engineering optimization is typically multiobjective and multidisciplinary with complex constraints, and the solution of such complex problems requires efficient optimization algorithms. Recently, Xin-She Yang proposed a bat-inspired algorithm for solving nonlinear, global optimisation problems. In this paper, we extend this algorithm to solve multiobjective optimisation problems. The proposed multiobjective bat algorithm (MOBA) is first validated against a subset of test functions, and then applied to solve multiobjective design problems such as welded beam design. Simulation results suggest that the proposed algorithm works efficiently.

description: We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with three different CCD-cameras at the University Observatory Jena with telescopes from 25 to 90 cm. The flare duration is almost one hour with an amplitude in the R-band of about 1.08 mag. The location of the flare star in a color-magnitude diagram is consistent with age and distance of the Pleiades. In the optical PSF of the flare star there are two 2MASS objects (unresolved in most images in the optical Jena PSF), so it is not yet known which one of them is responsible for this flare. The BVRIJHK colors yield spectral types of M1 and M2 with extinction being A_V=0.231+/-0.024 mag and A_V=0.266+/-0.020 for those two stars, consistent with the Pleiades cluster.

description: In a gray scale image the pixel value ranges from 0 to 255. But when we use pixel-value differencing (pvd) method as image steganographic scheme, the pixel values in the stego-image may exceed gray scale range. An adaptive steganography based on modified pixel-value differencing through management of pixel values within the range of gray scale has been proposed in this paper. PVD method is used and check whether the pixel value exceeds the range on embedding. Positions where the pixel exceeds boundary has been marked and a delicate handle is used to keep the value within the range. From the experimental it is seen that the results obtained in proposed method provides with identical payload and visual fidelity of stego-image compared to the pvd method.

description: We present the first imaging circular polarimetry of the anomalous X-ray pulsar (AXP) 4U 0142+61 at optical wavelengths. The AXP is the only magnetar that has been well studied at optical and infrared wavelengths and is known to have a complicated broad-band spectrum over the wavelength range. The optical polarimetric observation was carried out with the 8.2-m Subaru telescope at I-band. From the observation, the degree of circular polarization V was measured to be V=1.1+/-2.0%, or |V|<4.3% (90% confidence). The relatively large uncertainty was due to the faintness of the source (I=23.4-24.0). Considering the currently suggested models for optical emission from magnetars, our result is not sufficiently conclusive to discriminate the models. We suggest that because linear polarization is expected to be strong in the models, linear polarimetry of this magnetar should be conducted.

description: We propose a novel method to automatically compute the symmetry plane and correct the 3D orientation of patient brain images. Many images of the brain are clinically unreadable because of the misalignment of the patient's head in the scanner. We proposed an algorithm that represents the brain volume as a re-parameterized surface point cloud where each location has been parameterized by its elevation (latitude), azimuth (longitude) and radius. The removal of the interior contents of the brain makes this approach perform robustly in the presence of the brain pathologies, e.g. tumor, stroke and bleed. Thus, we decompose the symmetry plane computation problem into a surface matching routine. The search for the best matching surface is implemented in a multi-resolution paradigm so as to decrease computational time considerably. Spatial affine transform then is performed to rotate the 3D brain images and align them within the coordinate system of the scanner. The corrected brain volume is re-sliced such that each planar image represents the brain at the same axial level.

description: Children represent 25 percent of the population. Yet, 41 percent of all children live in low-income families and nearly one in every five live in poor families. Our very youngest children, infants and toddlers under age 3, appear to be particularly vulnerable with 44 percent living in low-income and 22 percent living in poor families. Winding up in a low-income or poor family does not happen by chance. There are significant factors related to children's experiences with economic insecurity, such as race/ethnicity and parents' education and employment. This fact sheet describes the demographic, socio-economic, and geographic characteristics of infants and toddlers and their parents — highlighting the important factors that appear to distinguish low-income and poor children in this age group from their less disadvantaged counterparts.

description: We compute the low energy effective field theory (EFT) expansion for single-field inflationary models that descend from a parent theory containing multiple other scalar fields. By assuming that all other degrees of freedom in the parent theory are sufficiently massive relative to the inflaton, it is possible to derive an EFT valid to arbitrary order in perturbations, provided certain generalized adiabaticity conditions are respected. These conditions permit a consistent low energy EFT description even when the inflaton deviates off its adiabatic minimum along its slowly rolling trajectory. By generalizing the formalism that identifies the adiabatic mode with the Goldstone boson of this spontaneously broken time translational symmetry prior to the integration of the heavy fields, we show that this invariance of the parent theory dictates the entire non-perturbative structure of the descendent EFT. The couplings of this theory can be written entirely in terms of the reduced speed of sound of adiabatic perturbations. The resulting operator expansion is distinguishable from that of other scenarios, such as standard single inflation or DBI inflation. In particular, we re-derive how certain operators can become transiently strongly coupled along the inflaton trajectory, consistent with slow-roll and the validity of the EFT expansion, imprinting features in the primordial power spectrum, and we deduce the relevant cubic operators that imply distinct signatures in the primordial bispectrum which may soon be constrained by observations.

description: The non-relativistic bosonic ground state is studied for quantum N-body systems with Coulomb interactions, modeling atoms or ions made of N "bosonic point electrons" bound to an atomic point nucleus of Z "electron" charges, treated in Born--Oppenheimer approximation. It is shown that the (negative) ground state energy E(Z,N) yields the monotonically growing function (E(l N,N) over N cubed). By adapting an argument of Hogreve, it is shown that its limit as N to infinity for l > l* is governed by Hartree theory, with the rescaled bosonic ground state wave function factoring into an infinite product of identical one-body wave functions determined by the Hartree equation. The proof resembles the construction of the thermodynamic mean-field limit of the classical ensembles with thermodynamically unstable interactions, except that here the ensemble is Born's, with the absolute square of the ground state wave function as ensemble probability density function, with the Fisher information functional in the variational principle for Born's ensemble playing the role of the negative of the Gibbs entropy functional in the free-energy variational principle for the classical petit-canonical configurational ensemble.
