description: Rationale In mouse models for atopic dermatitis (AD) hypothalamus pituitary adrenal axis (HPA) dysfunction and neuropeptide-dependent neurogenic inflammation explain stress-aggravated flares to some extent. Lately, cholinergic signaling has emerged as a link between innate and adaptive immunity as well as stress responses in chronic inflammatory diseases. Here we aim to determine in humans the impact of acute stress on neuro-immune interaction as well as on the non-neuronal cholinergic system (NNCS). Methods Skin biopsies were obtained from 22 individuals (AD patients and matched healthy control subjects) before and after the Trier social stress test (TSST). To assess neuro-immune interaction, nerve fiber (NF)-density, NF-mast cell contacts and mast cell activation were determined by immunohistomorphometry. To evaluate NNCS effects, expression of secreted mammal Ly-6/urokinase-type plasminogen activator receptor-related protein (SLURP) 1 and 2 (endogenous nicotinic acetylcholine receptor ligands) and their main corresponding receptors were assessed by quantitative RT-PCR. Results With respect to neuro-immune interaction we found higher numbers of NGF+ dermal NF in lesional compared to non-lesional AD but lower numbers of Gap43+ growing NF at baseline. Mast cell-NF contacts correlated with SCORAD and itch in lesional skin. With respect to the NNCS, nicotinic acetylcholine receptor α7 (α7nAChR) mRNA was significantly lower in lesional AD skin at baseline. After TSST, PGP 9.5+ NF numbers dropped in lesional AD as did their contacts with mast cells. NGF+ NF now correlated with SCORAD and mast cell-NF contacts with itch in non-lesional skin. At the same time, SLURP-2 levels increased in lesional AD skin. Conclusions In humans chronic inflammatory and highly acute psycho-emotional stress interact to modulate cutaneous neuro- immune communication and NNCS marker expression. These findings may have consequences for understanding and treatment of chronic inflammatory diseases in the future.

description: Reconfigurable intelligent surfaces (RISs) have become a promising technology to meet the requirements of energy efficiency and scalability in future six-generation (6G) communications. However, a significant challenge in RISs-aided communications is the joint optimization of active and passive beamforming at base stations (BSs) and RISs respectively. Specifically, the main difficulty is attributed to the highly non-convex optimization space of beamforming matrices at both BSs and RISs, as well as the diversity and mobility of communication scenarios. To address this, we present a greenly gradient based meta learning beamforming (GMLB) approach. Unlike traditional deep learning based methods which take channel information directly as input, GMLB feeds the gradient of sum rate into neural networks. Coherently, we design a differential regulator to address the phase shift optimization of RISs. Moreover, we use the meta learning to iteratively optimize the beamforming matrices of BSs and RISs. These techniques make the proposed method to work well without requiring energy-consuming pre-training. Simulations show that GMLB could achieve higher sum rate than that of typical alternating optimization algorithms with the energy consumption by two orders of magnitude less.

description: Reed-Solomon codes as nonbinary block codes with multiple burst-error-correcting capability are well suited for error control in fading channels. This thesis studies the effectiveness of Reed Solomon codes and provides a complete characterization of these codes for a class of land mobile satellite communication channels. Earlier studies on the performance of RS codes in mobile satellite channels did not consider shadowing. Furthermore, they considered only the slow fading case. In our simulation the effect of shadowing is taken into consideration and a fast fading assumption is used with system fading bandwidths of 1 to 10 percent of the transmission rate. This range of normalized fading bandwidths corresponds to vehicle speeds from 15 to 60 mph at bit rate of 2400 bps and 4800 bps for L-band carrier frequency. BER performance results show that RS codes can provide large improvement, however there is still 5 to 20 dB discrepancy between the performance in an AWGN channel and LMSAT channel. Therefore to obtain further improvement a novel receiver structure which employs fading prediction in conjunction with RS codes has been introduce and analyzed. With practical predictor lengths, simulated performance results show that the proposed technique greatly reduces the performance degradation caused by the fading channel.

description: This paper presents a systematic literature review on the impact of the neighborhood physical environment on mobility and social participation among people using mobility assistive technology (MAT). Peer-reviewed articles from eight databases published in French or English from 1990 to 2016 were searched. Thirty studies were included in this review. Factors related to neighborhood environmental features, mobility in transit, and accessibility of homes and public buildings influenced mobility and social participation of MAT users. The majority of reviewed studies combined different types of MAT, which made the interpretation of the results challenging. Few studies included walker, cane, and crutch users. Definitions of mobility and social participation lacked consistency and were often simplistic. Future empirical research needs to examine the impact of neighborhood physical environment factors separately for different MAT users. Causality and links between mobility and social participation of different MAT users at the neighborhood level should be further explored.

Subjects: subject: Biology, Neuroscience.

description: Post-transcriptional mechanisms regulating acetylcholinesterase (AChE) expression in muscle and neurons are relatively ill-defined, even though several studies have implicated mRNA stability as a means of controlling expression. We have, therefore, undertaken studies examining the role of post-transcriptional mechanisms in regulating AChE mRNA levels during neuronal differentiation, myogenic differentiation and in vivo following axotomy of the rat superior cervical ganglion (SCG). Specifically, using a combination of molecular techniques we have investigated the role of AChE's 3'-untranslated region (UTR) and have identified both cis- and trans-acting factors that modulate AChE mRNA levels. During neuronal differentiation of PC12 cells we determined that post-transcriptional mechanisms were predominantly responsible for the sustained increase in AChE mRNA since a modest increase in gene transcription occurred early and transiently. We examined the role of the AU-rich element (ARE) found in the 3'-UTR and of the RNA-binding protein (RBP) HuD in modulating AChE mRNA levels. Using a combination of complementary binding assays and transfection assays we demonstrated direct binding of HuD to the ARE and the stabilizing effect of this interaction. Given these results, we examined whether the ubiquitous Hu family protein, HuR, is implicated in post-transcriptional regulation of AChE during C2C12 myogenesis. Using similar approaches, we observed that the ARE and interactions with RBP complexes increased with differentiation and are important elements to AChE expression. We showed that HuR associates with the ARE and is involved in increased AChE transcript stability measured during myogenesis. Finally, we examined the relationship between HuD and AChE mRNA in neurons in vivo following SCG axotomy. Initially, we demonstrated that human HuD expressed in the hippocampus of HuD transgenic mice could bind AChE transcripts and increase AChE mRNA levels. Following SCG axotomy, we observed dramatic decreases in AChE mRNA levels and interactions with RBP complexes, including HuD. HuD protein and mRNA levels were also decreased as a result of axotomy. Exogenous expression of HuD in the SCG prior to axotomy prevented the decrease in ACNE mRNA. Accordingly, during the course of these studies we have identified an ARE in the AChE 3'-UTR and its binding partners HuD and HuR, as essential mediators of post-transcriptional mechanisms regulating AChE expression in neurons and muscle, respectively.

description: In today's competitive business world, it is important for decision makers to have access to decision support tools. One of these decision making areas is supplier selection in e-procurement. Supplier selection is a multi-criteria decision making process that deals with the optimization of conflicting objectives. If it is not supported by a system, this would be a complex and time consuming process. In spite of the fact that the term "supplier selection" is commonly used in the literature, few efforts have been dedicated to develop a system based on any of these methods. In this thesis, we propose a web based supplier selection decision support system based on the fuzzy analytic hierarchy process (AHP) method. To validate our choice of the Fuzzy AHP model and also to validate the conceptual design of our supplier selection decision support system, we conducted a case study in a local hospital.

description: Air pollution is a major health risk factor worldwide. Regular short- and long-time exposures to ambient particulate matter (PM) promote various diseases and can lead to premature death. Therefore, in Germany, air quality is assessed continuously at approximately 400 measurement sites. However, knowledge about this intermediate distribution is either unknown or lacks a high spatial-temporal resolution to accurately determine exposure since commonly used chemical transport models are resource intensive. In this study, we present a method that can provide information about the ambient PM concentration for all of Germany at high spatial (100 m * 100 m) and hourly resolutions based on freely available data. To do so we adopted and optimised a method that combined land use regression modelling with a geostatistical interpolation technique using ordinary kriging. The land use regression model was set up based on CORINE (Coordination of Information on the Environment) land cover data and the Germany National Emission Inventory. To test the model's performance under different conditions, four distinct data sets were used. (1) From a total of 8760 (365 * 24) available h, 1500 were randomly selected. From those, the hourly mean concentrations at all stations (ca. 400) were used to run the model (n = 566,326). The leave-one-out cross-validation resulted in a mean absolute error (MAE) of 7.68 (micro)gm-3 and a root mean square error (RMSE) of 11.20 (micro)gm-3. (2) For a more detailed analysis of how the model performs when an above-average number of high values are modelled, we selected all hourly means from February 2011 (n = 256,606). In February, measured concentrations were much higher than in any other month, leading to a slightly higher MAE of 9.77 (micro)gm-3 and RMSE of 14.36 (micro)gm-3, respectively. (3) To enable better comparability with other studies, the annual mean concentration (n = 413) was modelled with a MAE of 4.82 (micro)gm-3 and a RMSE of 6.08 (mircro)gm-3. (4) To verify the model's capability of predicting the exceedance of the daily mean limit value, daily means were modelled for all days in February (n = 10,845). The exceedances of the daily mean limit value of 50 (micro)gm-3 were predicted correctly in 88.67% of all cases. We show that modelling ambient PM concentrations can be performed at a high spatial-temporal resolution for large areas based on open data, land use regression modelling, and kriging, with overall convincing results. This approach offers new possibilities in the fields of exposure assessment, city planning, and governance since it allows more accurate views of ambient PM concentrations at the spatial-temporal resolution required for such assessments. © 2022 by the authors

description: Motivated by the great success of classical generative models in machine learning, enthusiastic exploration of their quantum version has recently started. To depart on this journey, it is important to develop a relevant metric to evaluate the quality of quantum generative models; in the classical case, one such example is the (classical) inception score (cIS). In this paper, as a natural extension of cIS, we propose the quantum inception score (qIS) for quantum generators. Importantly, qIS relates the quality to the Holevo information of the quantum channel that classifies a given dataset. In this context, we show several properties of qIS. First, qIS is greater than or equal to the corresponding cIS, which is defined through projection measurements on the system output. Second, the difference between qIS and cIS arises from the presence of quantum coherence, as characterized by the resource theory of asymmetry. Third, when a set of entangled generators is prepared, there exists a classifying process leading to the further enhancement of qIS. Fourth, we harness the quantum fluctuation theorem to characterize the physical limitation of qIS. Finally, we apply qIS to assess the quality of the one-dimensional spin chain model as a quantum generative model, with the quantum convolutional neural network as a quantum classifier, for the phase classification problem in the quantum many-body physics.

Publisher: name: University of British Columbia
Year: 2025

description: This research addresses the unique political landscape of Yukon First Nations including the imposition of the Indian Act, historical relocation of First Nations, and the impact of land claims agreements and modern treaties in Yukon. Two First Nations, Kluane FN and White River FN, have completely overlapped Traditional Territories. Kluane FN ratified their land claims agreement in 2003, while White River FN remains an Indian Act Band. In this context, I interviewed four Kluane Knowledge Keepers, all who directly negotiated and implemented Kluane FN land claim agreements. I did this to understand the development of land claims and self-government in the Kluane area. Focusing on intergenerational knowledge transfer, I used interviews to build a foundation of knowledge about the progression of land claims in Kluane including impacts on relationships between White River FN / Kluane FN governments stemming from the amalgamation. The Knowledge Keepers I interviewed had a profound desire to share their knowledge with Kluane Youth about why Kluane People have chosen this path. Land claims as understood through the Knowledge Holder interviews produced several key themes: implementation, negotiation, amalgamation / de-amalgamation, citizen engagement, relationships / conflict resolution, overlap, culture, Elders / Youth. I synthesised one story from each of the four interviews to exemplify different perspectives regarding the implementation of land claims using the most notable implementation challenge for Kluane FN, the 100 percent overlap. I then completed two focus group discussions with two Kluane Youth to establish their base land claims comprehension, before sharing with them the history behind land claims through the stories of the Knowledge Keepers. Then, as a group, we imagined fundamental components of an ideal future for Kluane People. My research created the conditions for Youth to use storytelling to deepen their relationships to the implementation of land claims in Kluane growing their collective leadership potential. The primary outcome of my research is that Youth can use this information about land claims and reflections from their engagement with this research process to imagine an ideal future for Kluane FN grounded in Kluane histories.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Engineering, Mechanical.

description: In the present study, it is demonstrated that the traditional superposition method lends itself successfully to obtaining of eigenvalues and mode shapes for rectangular shear deformable plates resting on uniform elastic edge supports. The effect of transverse shear deformation is taken into account by means of the first order shear deformation relationship developed by Mindlin. Uniform elastic rotational and translational supports of any stiffness magnitudes are considered to act simultaneously along the four edges. The effects of twisting edge restraint are investigated for the first time. The governing differential equations are satisfied exactly throughout the plate domain. Eigenvalues are tabulated for the first six vibration modes of square plates with identical stiffnesses along all edges. It is shown that all the three classical boundary conditions, namely, free, simply supported, and clamped, are approached when the stiffness coefficients are allowed to take on appropriate limits. These appear to be the first analytical solutions to these important elastically supported plate vibration problems obtained by the superposition method.
Optimization of Video Services for Cellular Networks using Mobile Edge Computing
Creators: name: Kumar, Shashwat
Publisher: name: Swinburne
Year: 2024

description: This thesis addresses the cellular networks congestion problem due to ever-increasing data demand. Since video services are the primary contributor of data traffic, in this thesis, we focused on optimizing the video delivery in mobile networks through edge caching. In edge caching, the data is stored on a small server or edge cloud deployed at the base station and significantly reduces the network load. We propose solutions to efficiently cache multi-bitrate regular videos and 360-degree videos on the edge cloud. We also propose a solution to enable 360-degree video streaming in cellular networks by reducing the bandwidth requirement.

description: In this paper, we explore the behavior of light ray trajectories in the exterior geometry of a rotating black hole within the Rastall theory of gravity, which is surrounded by an inhomogeneous anisotropic electronic cold plasma. By specifying the plasma's frequency profile, we derive fully analytical solutions for the temporal evolution of spacetime coordinates using elliptic integrals and Jacobi elliptic functions. These solutions illustrate various possible orbits. Throughout the study, we compare the results with those in the vacuum case, emphasizing the influence of plasma. Additionally, we utilize the analytical solutions to establish the lens equation for the considered spacetime. The investigation also addresses the significance of spherical photon orbits on critical trajectories, by presenting several examples.

CROSS-CULTURAL ENCOUNTERS: THE INFLUENCE OF COLONIAL TRADE IN AMITAV GHOSH'S SEA OF POPPIES
Creators: name: Lt. Dr. S. Ravibalan
Publisher: name: Zenodo
Year: 2024

description: This study explores the theme of cross-cultural encounters and the impact of colonial trade in Amitav Ghosh’s novel Sea of Poppies. Set against the backdrop of British colonialism and the Opium Wars, Ghosh portrays a diverse cast of characters whose lives intersect aboard the Ibis, a former slaving ship turned transport vessel for indentured laborers and opium. Through a postcolonial lens, this research analyzes how Ghosh navigates cultural hybridity, power dynamics, and identity formation in a globalized world. By examining the intricate connections forged through trade routes and colonial exploitation, the study sheds light on the complexities of cultural exchange and resistance in the context of 19th-century imperialism. Ultimately, this exploration reveals how Ghosh’s narrative not only chronicles historical events but also underscores the enduring legacy of colonialism on contemporary cultural identities.

description: Background: Optic pathway gliomas (OPGs) are present in 20% of children with neurofibromatosis 1 (NF1) but are less frequently observed in adults. Our goal was to determine the natural history of OPGs in children and adults with NF1. Results: We analyzed the features of OPGs and other intracranial lesions on 1775 head MRI scans of 562 unselected adults and children with NF1 collected between 2003 and 2015. 52 (9.3%) of 562 patients in this study had an OPG diagnosed on their MRI. The median age at first scan with an OPG present was 12.7 years. Of the 52 OPG patients, the intraorbital optic nerves were affected in 29 patients (56%), the prechiasmatic optic nerves were affected in 32 patients (62%), the optic chiasm was affected in 17 patients (33%) and the optic radiations were affected in 19 patients (37%). 29 patients had two or more areas affected. One patient had a newly-appearing OPG, and 1 patient showed progression. The rate of progression over 5 years was 2.4% (95% CI: 0.4% to 16%). Four patients showed partial regression of their OPGs, but we observed no case of complete regression during this study. The rate of regression over 5 years was 8.9% (95% confidence intervals: 2.8% to 26%). We found the presence of UBOs and the presence of OPGs in individual patients to be highly associated (p = 0.0061). Conclusion: OPGs are more common in older adults with NF1 than previously thought. The occurrences of unidentified bright objects (UBOs) and asymptomatic OPGs are associated with each other. This suggests the possibility that OPGs that remain asymptomatic may differ pathogenically from those that become symptomatic.

description: We study an asymptotically free theory of $N$ relativistic Dirac fermions and a real scalar field coupled by Yukawa and scalar self-interactions in three dimensions using functional renormalisation. In the limit of many fermion flavours, the cubic scalar coupling becomes exactly marginal due to quantum fluctuations, leading to a line of strongly-coupled infrared fixed points. Fermion mass can be generated through a quantum phase transition even if chiral symmetry is absent. The line of fixed points terminates at a critical endpoint due to the loss of vacuum stability. Exactly at the endpoint, scale symmetry is broken spontaneously, leading to the generation of fermion mass. Intriguingly, the absence of chiral symmetry is a prerequisite for the spontaneous generation of fermion mass, and not a consequence thereof. We also highlight close similarities between Gross-Neveu and Gross-Neveu--Yukawa theories at and away from critical points, and establish the large-$N$ equivalence of their functional RG flows and quantum effective actions. Further implications including for conformal field theories are indicated.

description: In this Letter, we propose to detect the interaction of a hypothetical coherently evolving cosmological scalar field with an orbital network of quantum sensors, focusing on the GPS satellite network as a test example. Cosmological scenarios, such as a scalar-tensor theory for dark energy or the axi-Higgs model, suggest that such a field may exist. As this field would be (approximately) at rest in the CMB frame, it would exhibit a dipole as a result of the movement of our terrestrial observers relative to the CMB. While the current sensitivity of the GPS network is insufficient to detect a cosmological dipole, future networks of quantum sensors on heliocentric orbits, using state-of-the-art atomic clocks, can reach and exceed this requirement.

description: This research study indicated that the ability of Literature-Based Discovery system to establish plausible connections enables researchers in gaining new knowledge for hypothesis generation and testing. Several challenges affecting the perceived usability of the Literature-Based Discovery system were identified from the interviews with four researchers with biomedical background. The interview results revealed that the participants faced different usability challenges at the inquiry, investigation and navigation stages of Literature-Based Discovery style hypothesis generation activity. Despite the challenges, findings from the interviews also showed that Literature-Based Discovery systems are capable of broadening users' knowledge base through its employment of graph visualization in result presentation.

description: We report the finding of a new, local diffusion instability in a protoplanetary disk, which can operate in a dust fluid, subject to mass diffusion, shear viscosity, and dust-gas drag, provided diffusivity, viscosity, or both decrease sufficiently rapidly with increasing dust surface mass density. We devise a vertically averaged, axisymmetric hydrodynamic model to describe a dense, mid-plane dust layer in a protoplanetary disk. The gas is modeled as a passive component, imposing an effective, diffusion-dependent pressure, mass diffusivity, and viscosity onto the otherwise collisionless dust fluid, via turbulence excited by the gas alone, or dust and gas in combination. In particular, we argue that such conditions are met when the dust-gas mixture generates small-scale turbulence through the streaming instability, as supported by recent measurements of dust mass diffusion slopes in simulations. We hypothesize that the newly discovered instability may be the origin of filamentary features, almost ubiquitously found in simulations of the streaming instability. In addition, our model allows for growing oscillatory modes, which operate in a similar fashion as the axisymmetric viscous overstability in dense planetary rings. However, it remains speculative if the required conditions for such modes can be met in protoplanetary disks.

Subjects: subject: Mathematics.

description: In this thesis the question of optimal control of systems governed by B-evolutions is considered. First, a necessary conditions of optimality for a Lagrange problem subject to a semilinear systems is derived. Two cases are carried out: In the first case the Frechet differentiability of the cost integrand with respect to the control variable is assumed and in the second only the continuity. Then these results are applied to a linear quadratic regulator problem. Two results are presented one of which contains control cost and the other does not. The optimal control law is given by the solution of an appropriate operator Riccati differential equations. Finally, using the calculus of variation a result is proved on the existence of optimal controls.

description: The solubilities of the hydrocarbons n-butane, n-pentane, n-hexane, n-octane, and n-nonane in liquid methane and of n-hexane in the mixed solvents of methane and ethane and of methane and propane were obtained using a forced vapour recirculation apparatus. The liquid phase was sampled and analysed by gas chromatography. Liquid concentration ranges from 28.30 mole percent at 113.3K to 81.15 mole percent at 129.K for n-butane; from 5.09 mole percent at 123.4K to 41.19 mole percent at 131.25K for n-pentane; from 1.20 mole percent at 149.K to 17.95 mole percent at 166.2K for n-hexane; from 0.04 mole percent at 156.3K to 0.64 mole percent at 179.7K for n-octane; and from 0.03 mole percent at 161.6K to 0.18 mole percent at 184.3K for n-nonane. The solubility of n-hexane in the mixed solvents methane-ethane and methane-propane were also determined in order to assess the enhancement effect of the solvents ethane and propane. The n-hexane concentration in the mixed solvents were from 0.18 mole percent at 114K to 20.39 mole percent at 154.8K in the mixed solvents of methane and ethane and from 0.65 mole percent at 120.4K to 15.78 mole percent at 153.K in the mixed solvents of methane and propane. An attempt was made to correlate the experimental results through the liquid activity coefficient which was calculated by means of the Redlich-Kwong equation of state with a modified procedure.
Structural changes in a macrozoobenthos assemblage after imidacloprid pulses in aquatic field-based microcosms
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2013

description: A field-based microcosm experiment was performed to investigate the effects of repeated pulses of the neonicotinoid insecticide imidacloprid on a lentic benthos assemblage. This specific microcosm method was chosen because it allows for both testing of a wide range of organisms under natural conditions and as well as gaining insight into intraspecific and interspecific interactions. The macrozoobenthos that colonised the microcosms was exposed to three pulses each 1 week apart at nominal concentrations ranging from 0.6 to 40 ìg/L. Imidacloprid underwent fast aqueous photolysis due to optimal sunlight conditions during the test phase (half-life = 28 ş 8 h [monitored for 21 days]). Nonetheless, decreased abundance and emergence of Ephemeroptera and decreased survival of chironomid species of the subfamilies Tanypodinae and Orthocladiinae were observed at time-weighted average concentrations of 2.3 ìg/L. In contrast, the gastropod Radix sp. became dominant at high imidacloprid concentrations, probably due to decreased competition for food with sensitive species. The results of this study show that repeated short-term contamination of imidacloprid at low concentration levels may affect aquatic ecosystems even under optimal conditions for photodegradation. The microcosm approach, with its simple and field-relevant design, proved to be a useful tool for assessing the effects of imidacloprid contamination.Quelle: http://link.springer.com/

Pagenumber problem.

Subjects: subject: Computer Science.

description: A "book-embedding" of a graph G comprises of embedding the graph's nodes along the spine of a book, and embedding the edges on the pages so that the edges embedded on the same page do not intersect. This is also referred to as the page model. The "pagenumber" of a graph is the thickness of the smallest (in number of pages) book into which G can be embedded. A literature review of the one dimensional pagenumber problem is presented, and several two dimensional pagenumber models are proposed. Evolutionary computing methods on problems whose solution space comprises of permutations are reviewed. Since the pagenumber problem is known to be NP-complete, we describe two solutions using Hill Climbing methods and one solution using Genetic Algorithms for one and two-dimensional models. Two two-dimensional models are considered namely the square and rook models. We have given a unified framework for all three pagenumber models, in which a solution is a pair of two permutations (of nodes and edges), and which differ only by criteria for edge intersections. Experimental results on several kinds of graphs are then given.
