description: The novel bipyridine–terpyridine–phenazine ligand 6-pyrid-(tetrapyrido[2,3-a:2′,3′-c:3′′,2′′-h:2′′′,3′′′-j]phenazine (I) was prepared by condensation reaction of 5,6-diamino-l,10-phenanthroline (4) and 2-(pyrid-2′-yl)-1,10-phenanthroline-5,6-dione (6) and characterized using conventional methods. Poor solubility of the ligand led us to the preparation of its Ru(II) complexes to investigate the change in its solubility for further characterizing the ligand on the metal ion. [Ru(ttp)(I)](PF6)2 complex was prepared using the reaction of the ligand (I) and [Ru(ttp)Cl3] complex, where ttp is 4′-(4-Methylphenyl)-2,2′:6′,2′′-terpyridine. A different route for the preparation of [Ru(ttp)(I)](PF6)2 was introduced. Synthesis of the ligand (I) on the complex by a condensation reaction of [Ru(ttp)(6)](PF6)2, where ligand (6) is 2-(pyrid-2′-yl)-1,10-phenanthroline-5,6-dione, with 5,6-diamino-l,10-phenanthroline (4) was conducted. The spectroscopic measurements of both products which have been obtained through the two different routes were compared. We observed that the NMR, LC-MS, and UV spectra of the both products were identical.
title: Operational support systems for satellite communications

description: The role of satellite communications is changing from providing bandwidth linking network operators interconnections towards providing IP enabled communications to end users. This migration from few high-value routes towards many low-value routes means that integration and automation of processes with terrestrial networks becomes critical in driving down unit costs. Integration and automation is necessary on all planes: user, control and management. In satellite communications, management aspects, underpinned by Operational Support Systems (OSS) have received the least research attention, making this a valuable topic for study.

In most areas, OSS for satellite systems are similar to other domains. However there are some notable areas of difference which have been the focus of this research. The eTOM business framework, developed by the TMF, has been used to highlight aspects of OSS unique to satellite. Since satellite capacity represents the highest operational cost of a satellite route, effective management while minimising the overhead traffic is critical. The transmission of IP packets is assumed and the real-time measurement of QoS parameters such as packet delay and loss emerged as the most important differences.

A number of approaches to QoS measurement are feasible, however the use of trace packets is most promising especially for high network loads. An experiment compares the results from simulations, mathematical models and from a test network, using Poisson and self-similar traffic flows. The relationship between measurement accuracy and trace packet intensity is explored and the measurement response time to steps in traffic load is estimated. It is discovered that measurement accuracy improves as the queue load increases, in contrast to alternative approaches such as sampling of user packets. The response time to steps depends upon the degree of self-similarity and is generally longer than the times recommended by standards. A pragmatic approach to management of different modes is proposed where the measurement method is changed depending on the load.

description: We present new 850$μ$m SCUBA-2 observations for a sample of 19 heavily reddened Type-I quasars at redshifts $z\sim$2 with dust extinctions of A$_{\rm{V}} \simeq 2-6$ mag. Three of the 19 quasars are detected at $>$3$σ$ significance corresponding to an 850$μ$m flux-limit of $\gtrsim$4.8 mJy. Assuming the 850$μ$m flux is dominated by dust heating due to star formation, very high star formation rates (SFR) of $\sim$2500-4500 M$_\odot$ yr$^{-1}$ in the quasar host galaxies are inferred. Even when considering a large contribution to the 850$μ$m flux from dust heated by the quasar itself, significant SFRs of $\sim$600-1500 M$_\odot$ yr$^{-1}$ are nevertheless inferred for two of the three detected quasars. We stack the remaining 16 heavily reddened quasars and derive an average 3$σ$ upper limit on the SFRs in these quasar host galaxies of $

description: The very low temperature properties of two pyrochlore compounds, Yb2Ti2O7 and Gd2Sn2O7, were investigated using an ensemble of microscopic and bulk techniques. In both compounds, a first order transition is evidenced, as well as spin dynamics persisting down to the 20mK range. The transition however has a quite different character in the two materials: whereas that in Gd2Sn2O7$ (at 1K) is a magnetic transition towards long range order, that in Yb2Ti2O7 (at 0.24K) is reminiscent of the liquid-gas transition, in the sense that it involves a 4 orders of magnitude drop of the spin fluctuation frequency; furthermore, no long range order is observed. These unusual features we attribute to frustration of the antiferromagnetic exchange interaction in the pyrochlore lattice.

description: No abstracts are to be cited without prior reference to the author.The potential impact of climate change on industry is frequently speculated about, but the actual historical impact of climate change on industry is rarely studied. Studies of the impact of climate change on fisheries have been largely simulation based or speculative and rarely use historical data. No studies of climate change test to see whether economic factors or physical and biological factors have a greater impact on the fishing industry. If policymakers are to make informed climate policy decisions environmental economists need to forecast the likely consequences of climate change on industry and be able to judge whether these consequences are large or small compared with changes due to other causes. In this paper, the impact of climate change on Irish fisheries is examined using a panel data set of 506 observations, consisting of 46 cross-sectional units and 11 longitudinal units. A comparison is made of the impact of economic factors and the impact of climate change on fisheries catch. It is concluded that climate change has had a considerable impact on the Irish fishing industry. An attempt is made to quantify the monetary impact of climate change on Irish fisheries and the loss to specific Irish fishing ports.
Two-point functions at arbitrary genus and its resurgence structure in a matrix model for 2D type IIA superstrings

description: In the previous papers, it is pointed out that a supersymmetric double-well matrix model corresponds to a two-dimensional type IIA superstring theory on a Ramond-Ramond background at the level of correlation functions. This was confirmed by agreement between their planar correlation functions. The supersymmetry in the matrix model corresponds to the target space supersymmetry and it is shown to be spontaneously broken by nonperturbative effect. Furthermore, in the matrix model we computed one-point functions of single-trace operators to all order of genus expansion in its double scaling limit. We found that this expansion is stringy and not Borel summable and hence there arises an ambiguity in applying the Borel resummation technique. We confirmed that resurgence works here, namely this ambiguity in perturbative series in a zero-instanton sector is exactly canceled by another ambiguity in a one-instanton sector obtained by instanton calculation. In this paper we extend this analysis and study resurgence structure of the two-point functions of the single trace operators. By using results in the random matrix theory, we derive two-point functions at arbitrary genus and see that the perturbative series in the zero-instanton sector again has an ambiguity. We find that the two-point functions inevitably have logarithmic singularity even at higher genus. In this derivation we obtain a new result of the two-point function expressed by the one-point function at the leading order in the soft-edge scaling limit of the random matrix theory. We also compute an ambiguity in the one-instanton sector by using the Airy kernel, and confirm that ambiguities in both sectors cancel each other at the leading order in the double scaling limit. We thus clarify resurgence structure of the two-point functions in the supersymmetric double-well matrix model.

description: The spread of the Coronavirus disease-2019 epidemic has caused many courses and exams to be conducted online. The cheating behavior detection model in examination invigilation systems plays a pivotal role in guaranteeing the equality of long-distance examinations. However, cheating behavior is rare, and most researchers do not comprehensively take into account features such as head posture, gaze angle, body posture, and background information in the task of cheating behavior detection. In this paper, we develop and present CHEESE, a CHEating detection framework via multiplE inStancE learning. The framework consists of a label generator that implements weak supervision and a feature encoder to learn discriminative features. In addition, the framework combines body posture and background features extracted by 3D convolution with eye gaze, head posture and facial features captured by OpenFace 2.0. These features are fed into the spatio-temporal graph module by stitching to analyze the spatio-temporal changes in video clips to detect the cheating behaviors. Our experiments on three datasets, UCF-Crime, ShanghaiTech and Online Exam Proctoring (OEP), prove the effectiveness of our method as compared to the state-of-the-art approaches, and obtain the frame-level AUC score of 87.58% on the OEP dataset.

description: This study examines retailer pricing behavior for iceberg lettuce shipped from California and Arizona, maturegreen and vine-ripe tomatoes shipped from California and Florida, and lettuce-based fresh salads. A switching regression model is used to examine oligopsony power. Market power over consumers is inferred from selling price, selling and acquisition cost, and estimated price elasticities of demand. Evidence suggests buyers are often able to exercise oligopsony power in procuring fresh produce commodities. Unilateral monopoly power granted by geographic and brand differentiation allows retailers to exercise market power over consumers, in the sense of marking up prices in excess of full marginal costs.

description: Modified graphene oxide by acetic acid moiety (GO/COOH) was synthesized and employed in the ultrasoundassisted oxidative-adsorptive desulfurization processes. The modified graphene oxide was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy The fabricated material was applied to simultaneous oxidation and adsorption of dibenzothiophene (DBT) from model fuel. Adsorption studies were carried out to evaluate its potential for DBT removal. The effects of contact time, initial DBT concentration, and temperature on the removal efficiency of the catalyst-adsorbent were investigated. The equilibrium adsorption results was well-described by the Freundlich isotherm model (at room temperature) and oxidation-adsorption of DBT were achieved by GO/COOH with an outstanding adsorption capacity of 370 mg g−1. The adsorption process followed a pseudo-first-order kinetic model and the adsorption kinetic data suggests that physical interactions are mainly involved on the entire adsorption process (Ea < 40 kJ mol−1). The initial sulfur content of 1000 ppm was reduced to<50 ppm within 300 min, achieving a sulfur removal of about 95%. As a whole, a model fuel with ultra-low sulfur content was obtained by the developed procedure and GO/COOH shows a high potential for effective desulfurization of diesel fuel as a catalyst-adsorbent.

description: This study developed and administered a questionnaire to identify feeding practices among low-income African- American mothers and eating behaviors in their preschool children that are associated with childhood obesity. The findings do not appear to implicate feeding practices to childhood obesity in this sample of preschoolers. However, before concluding that feeding practices are not associated with childhood weight status, further research is needed to ensure that the constructs used accurately assess feeding practices in specific populations.. Further research is also needed using a larger sample of overweight children to compare the findings with those among children of normal weight.

description: The Benes network has been used as a rearrangeable network for over 40 years, yet the uniform $N(2 \log N-1)$ control complexity of the $N \times N$ Benes is not optimal for many permutations. In this paper, we present a novel $O(\log N)$ depth rearrangeable network called KR-Benes that is {\it permutation-specific control-optimal}. The KR-Benes routes {\it every} permutation with the minimal control complexity {\it specific} to that permutation and its worst-case complexity for arbitrary permutations is bounded by the Benes; thus it replaces the Benes when considering control complexity/latency. We design the KR-Benes by first constructing a restricted $2 \log K +2$ depth rearrangeable network called $K$-Benes for routing $K$-bounded permutations with control $2N \log K$, $0 \leq K \leq N/4$. We then show that the $N \times N$ Benes network itself (with one additional stage) contains every $K$-Benes network as a subgraph and use this property to construct the KR-Benes network. With regard to the control-optimality of the KR-Benes, we show that any optimal network for rearrangeably routing $K$-bounded permutations must have depth $2 \log K + 2$, and therefore the $K$-Benes (and hence the KR-Benes) is optimal.

description: Renewable energy sources act as a boon tosustain environmental changes in the society. Convertersand inverters are prime components in the advancementin the field of power electronic systems using renewableenergy sources. Few sources such as photovoltaicmodules, fuel cells or energy storage devices, such assuper capacitors or batteries require these powerelectronic converts in its best form in order to help thesociety in its sustainable development. Such sustainabledevelopment based devices impact enormously inbalancing with the environmental changes. These powerelectronic modules play a very important role in handlingand solving generation, transmission, distribution andalso consumer end appliances. The fact that theresearchers have a lack of familiarity on the powerelectronic modules, leads to complexity in choosingappropriate power electronic modules for standalonerenewable energy sources. Inappropriate selection ofthese modules may lead to the deterioration of theefficiency of the system and eventually detriment of theequipments too. There are many discussions goingaround on the usefulness of hybridization of renewableenergy resources by considering the optimum utilizationand compensation of the investment done on thesesources. Therefore, considering a feasible power modulefor the hybrid system, further increases the complexity inchoosing the appropriate power electronic modules. Thisis to propose that this paper will emphasis on differentpower electronic converters that have been presented inthis literature which are suitable for stand-alonerenewable energy sources. To add on to that, it alsopresents different class of power converter topologiesalong with the technical specifications, control structuresand their boundaries. It also gives an insight on theevaluation of the existing converter topologies byconsidering the different type of parameters. Throughwhich a suitable characterization of promising convertertopology can be opted for the environmental changes.

description: Reverse inference is a crucial inferential strategy employed by neuroscientists to infer the engagement of a cognitive pro- cess from observed brain activation in functional magnetic resonance imaging studies. Despite its widespread use, in recent years reverse inference faced increasing skepticism, par- ticularly after Russell Poldrack authoritatively criticized its uncontrolled use in his influential 2006 paper. The general aim of the thesis is to provide an assessment of the current debate about reverse inference at the interface between neuroscience and the philosophy of science, by evaluating the models and methods proposed to improve the theory and practice of reverse inference. To do this, I offer three main contributions to the debate. In the first part of the thesis, I offer a comprehensive and updated overview of the problem of reverse inference in cur- rent cognitive neuroscience, emphasizing both technical and methodological issues. In the second part, I present and discuss the different philo- sophical models of reverse inference proposed in the literature, assessing their relative advantages and limitations. I also dis- cuss two novel models of reverse inference, one based on Bayesian confirmation theory and one based on the idea of inference to the best explanation. In the third part, I present the main results of a systematic review of the literature, aiming at evaluating the impact of NeuroSynth, the most widely employed meta-analytical soft- ware for performing reverse inference, on current practice in neuroscientific research.

description: Angle-resolved photoemission spectroscopy (ARPES) has revealed peculiar properties of mobile dopants in correlated anti-ferromagnets (AFMs). But describing them theoretically, even in simplified toy models, remains a challenge. Here we study ARPES spectra of a single mobile hole in the $t-J$ model. Recent progress in the microscopic description of mobile dopants allows us to use a geometric decoupling of spin and charge fluctuations at strong couplings, from which we conjecture a one-to-one relation of the one-dopant spectral function and the spectrum of a constituting spinon in the \emph{undoped} parent AFM. We thoroughly test this hypothesis for a single hole doped into a 2D Heisenberg AFM by comparing our semi-analytical predictions to previous quantum Monte Carlo results and our large-scale time-dependent matrix product state (td-MPS) calculations of the spectral function. Our conclusion is supported by a microscopic trial wavefuntion describing spinon-chargon bound states, which captures the momentum and $t/J$ dependence of the quasiparticle residue. Our conjecture suggests that ARPES measurements in the pseudogap phase of cuprates can directly reveal the Dirac-fermion nature of the constituting spinons. Specifically, we demonstrate that our trial wavefunction provides a microscopic explanation for the sudden drop of spectral weight around the nodal point associated with the formation of Fermi arcs, assuming that additional frustration suppresses long-range AFM ordering. We benchmark our results by studying the cross-over from two to one dimension, where spinons and chargons are confined and deconfined respectively.

A special attention is paid to the phenomenon of primordial black holes evaporation. They act like black body to all kinds of radiation, including gravitons, and, therefore, emit an equilibrium spectrum of gravitons during its evaporation. Limit on the density of high frequency gravitons in the Universe is obtained, and possibilities of their detection are briefly discussed.

title: Biochemical mechanisms of apoptosis: ordering of the biochemical events in chemical-induced apoptosis.
Creators: name: Zhuang, Jianguo
Publisher: name: The Open University
Year: 1999

description: Apoptosis is an important form of cell death induced by anti-cancer drugs and chemicals. The biochemical mechanisms of chemical-induced apoptosis remain, however, largely unknown, and the major biochemical events in this model of apoptosis are poorly characterised.

In this study, apoptosis, induced in human monocytic THP.l cells by etoposide and N-tosyl-L-phenylalanyl chloromethyl ketone and in leukaemic U937 cells by etoposide, was accompanied by the release of mitochondrial cytochrome c, activation of caspases, proteolysis of poly(ADP-ribose) polymerase (PARP), DNA fragmentation, externalisation of phosphatidylserine (PS), and reduction in mitochondrial membrane potential (ɅѰm). Time course studies demonstrated that activation of caspases occurred prior to both PS externalisation and reduction in A\|/m. This was further supported by the observation that the caspase inhibitor, benzyloxycarbonyl-Val-Ala-Asp (OMe) fluoromethyl ketone (Z-VAD.FMK) inhibited all the ultrastructural and biochemical characteristics of apoptosis except the release of cytochrome c. The execution phase of apoptosis may thus be initiated by the translocation of cytochrome c to the cytosol, where it interacts with dATP and apoptotic-protease activating factor-1, resulting in activation of the initiator caspase-9, which in turn activates effector caspases, such as -3 and -7. Cytochrome c release was a later event in non-apoptotic cell death occurring after commitment to cell death and without caspase activation. Thus its release may represent a commitment to cell death in chemical-induced apoptosis.

 This study also showed that in cells triggered into apoptosis the plasma membrane changes leading to recognition and phagocytosis may be uncoupled from other features of apoptosis by using the mitochondrial inhibitors, antimycin A and oligomycin. These inhibitors blocked increased plasma membrane permeability, PS externalisation and recognition by two classes of phagocytes but not activation of caspases-3 and -7, PAR? cleavage or DNA fragmentation in THP.l cells. PS externalisation was also dissociated from caspase activation in U937 cells. Thus cell surface changes governing safe clearance of apoptotic cells may be regulated by an independent pathway to those mediated by caspases. This finding may have important consequences for attempts to manipulate cell death for therapeutic gain in vivo.

 Finally, this study demonstrated that in chemical-induced apoptosis caspases functioned solely as executioners and activation of caspases occurred after commitment to cell death, through post-mitochondrial activation pathway(s). Z- VAD.FMK inhibited apoptosis at a stage after this commitment by blocking the post- mitochondrial activation cascade of caspases. This contrasted to its effect in death receptor-mediated apoptosis in U937 cells, where Z.VAD.FMK inhibited apoptosis prior to commitment to cell death induced by tumour necrosis factor-ɑ.

description: We point out that ferromagnetic superconductors with triplet pairing and strong spin-orbit coupling are even in the simplest case at least two-band superconductors. The Gor'kov type formalism for such superconductors is developed and the Ginzburg-Landau equations are derived. The dependence of the critical temperature on the concentration of ordinary point-like impurities is found. Its nonuniversality could serve as a qualitative measure of the two-band character of ferromagnetic superconductors. The problem of the upper critical field determination is also discussed.

description: No abstracts are to be cited without prior reference to the author.The decadal and multi-decadal variability of marine ecosystems in the Northwest Pacific (NWP) is largely controlled by the West Pacific (WP) pattern in the middle troposphere and its near-surface counterpart, the North Pacific Oscillation (NPO). A comparison of the long-term changes in winter indices of the WP pattern and North Pacific Gyre Oscillation (NPGO) for the 1950-2012 period allowed for identifying several decadal and two multi-decadal climatic regimes in the NWP: 1963-1986 and 1987-2011/12. Each multi-decadal regime is associated with the certain large-scale sea surface temperature anomaly (SSTA) pattern, the persistence and SSTA trend of which determine the upward or downward tendencies in abundance of commercial fish populations in the NWP (salmons, |Japanese sardine, Japanese anchovy, etc.) and the character of statistical relationships between SST and fish survival. The decadal and multi-decadal climatic transitions are accompanied by a sharp change in structure and productivity of marine ecosystems. The biological predictors of a new climatic regime appeared in the NWP in the late 2000s. They preceded the climatic shift of 2011/2012. So, we consider the drastic changes occurred in the Northwest Pacific in winter of 2011/2012 as both the climatic and ecosystem regime shift.

The purpose of the review is to help identify future research needs and opportunities to exploit administrative data systems and recurring national surveys. The programs covered are the Food Distribution Program on Indian Reservations (FDPIR), the Food Stamp Program (FSP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), the National School Lunch Program, the School Breakfast Program, and the Commodity Supplemental Food Program (CSFP). Research topics of continuing importance include the impacts of reservation food assistance on health and nutrition, the characteristics that make nutrition education effective on reservations, the dynamics of program participation, and the contribution of tribal administration to program coordination.

description: We present the first detection of diffuse dust in the intra-cluster medium of the Virgo cluster out to $\sim$0.4 virial radii, and study the radial variation of its properties on a radial scale of the virial radius. Analysing near-UV - $i$ colours for a sample of $\sim12000$ background galaxies with redshifts $0.02 < z < 0.8$, we find significant colour reddening and relate it to variation in $E(B-V)$ values. The $E(B-V)$ mean profile shows a dust component characterised by an average reddening $E(B-V)\sim0.042 \pm 0.004$ mag within 1.5 degrees ($\sim0.3\, r_{vir}$) from the cluster centre. Assuming a Large Magellanic Cloud extinction law, we derive an average visual extinction $A_{V} = 0.14\pm 0.01$ for a total dust mass, $M_{d} = 2.5\pm0.2\times10^{9}M_{\odot}$, hence a dust-to-gas mass ratio $M_{d}/M_{g} = 3.0\pm 0.3 \times 10^{-4}$. Based on the upper limits on the flux density $\mathrm{I_{250μm} = 0.1\, MJy sr^{-1}} $ derived from $Herschel$ data, we estimate an upper limit for the dust temperature of $T_{d} \sim 10\, K$. However, similar densities can be obtained with dust at higher temperatures with lower emissivities. The Virgo cluster has diffuse dust in its intra-cluster medium characterised by different physical properties as those characterising the Milky Way dust. The diffuse dust in Virgo is transported into the cluster space through similar phenomena (stripping) as those building up the optical intra-cluster light, and it constitutes an additional cooling agent of the cluster gas.

description: Low participation rates in the Food Stamp Program (FSP) by poor elderly individuals have been a persistent problem. Historically, no more than one-third of eligible elderly have participated in the FSP—a participation rate far lower than that of any other major demographic group. To address the low participation rates among the elderly, USDA is funding the Elderly Nutrition Demonstrations—six separate pilot programs that are testing three alternative ways to increase elderly participation in the FSP. This report presents the design for evaluating the six demonstrations. The design includes an impact analysis to evaluate the effects of the demonstrations on FSP participation, average benefit levels, client satisfaction, and ongoing administrative costs. The design also includes a process analysis to describe the implementation process and to identify the effects of the demonstrations on stakeholders.

description: The contribution of this paper is to investigate the impact of citrus exports on the economic growth on Tunisia since it never been treated before. In order to achieve this purpose, annual data were collected from the reports of Tunisian Central Bank for the periods between 1970 and 2016 was tested by using co integration analysis of Error Correction Model. According to the result of the analysis, citrus exports do not influence on economic growth in the long term. However, empirical results show that there is a positive unidirectional causality from citrus exports to economic growth in the short run. These results provide evidence that citrus exports, thus, are not seen as source of economic growth in Tunisia because the miserable economic strategy. For this reason, it is very important to make new reforms and to create robustness strategies to refine investment and trade strategy in this sector, so it can support economic growth in Tunisia.

description: The cooling mechanism of compact stars with quark cores in the color-flavor locked phase is discussed. It is argued that the high thermal conductivity of the quark core plays a key role in the stellar cooling. It implies that the cooling time of compact stars with color-flavor locked quark cores is similar to that of ordinary neutron stars, unless the star is almost completely made of color-flavor locked quark matter.

description: Lawinen zählen zu den Naturgefahren. Natürliche Lawinen entstehen im Winter meist dann, wenn es heftig schneit oder taut. Kürzere Winter und generell weniger Schnee in den nächsten Jahren mögen vermuten lassen, dass die Anzahl an Lawinen in der Zukunft zurück geht. Andererseits sagen Klimamodelle für Mitteleuropa eine Zunahme der Starkniederschlagsereignisse voraus. Große Neuschneemengen und somit erhöhte Lawinenaktivität in hochalpinen Lagen wären die Folge. Wir diskutieren, inwiefern die Grundvoraussetzungen für Lawinen zukünftig erfüllt sein werden. Doch sie allein reichen nicht aus, um die Lawinengefahr abzuleiten. Erst mit Hilfe der relevanten Lawinentypen und der typischen Lawinenprobleme können wir einen detaillierten Ausblick wagen, wie sich die Naturgefahr Nummer 1 im Winter verändern könnte – auch wenn uns die Forschung bisher nur wenig über die Zukunft der Lawinengefahr sagt. Avalanche danger in climate change: Snow avalanches are natural hazards that occur naturally in periods of severe winter weather. Shorter winter seasons and generally less snow in the future may suggest a decreasing number of avalanches. On the other hand, in central Europe intense precipitation is projected to become more frequent resulting in more intense snowfall at higher elevations in the Alps. With these partly conflicting views the effect of a changing climate on future avalanche danger is not clear. We discuss the prerequisites, such as abundant snow, but also other important contributory factors to untangle the different views. Introducing the concepts of avalanche type and avalanche problems we shed some light on possible future characteristics of avalanche danger in alpine areas, albeit current research only provides limited answers.

description: Executing machine learning (ML) pipelines in real-time on radiology images is hard due to the limited computing resources in clinical environments and the lack of efficient data transfer capabilities to run them on research clusters. We propose Niffler, an integrated framework that enables the execution of ML pipelines at research clusters by efficiently querying and retrieving radiology images from the Picture Archiving and Communication Systems (PACS) of the hospitals. Niffler uses the Digital Imaging and Communications in Medicine (DICOM) protocol to fetch and store imaging data and provides metadata extraction capabilities and Application programming interfaces (APIs) to apply filters on the images. Niffler further enables the sharing of the outcomes from the ML pipelines in a de-identified manner. Niffler has been running stable for more than 19 months and has supported several research projects at the department. In this paper, we present its architecture and three of its use cases: an inferior vena cava (IVC) filter detection from the images in real-time, identification of scanner utilization, and scanner clock calibration. Evaluations on the Niffler prototype highlight its feasibility and efficiency in facilitating the ML pipelines on the images and metadata in real-time and retrospectively.

title: Innate immune responses induced by Chlamydia pneumoniae infection
Creators: name: Magdalenić, Vjera
Publisher: name: The Open University
Year: 2005

description: In the current project innate immune responses to C. pneumoniae infection were studied, using a human in vitro model: a combination of lung epithelial cell lines (HEp-2 and A549) and primary blood-derived monocyte-derived macrophages (MdMs). The experiments were designed with a view to identify the host-pathogen interactions early in the infection that may lead to persistence and the development of chronic diseases such as atherosclerosis. Infected epithelial cells and MdMs released IL-8 and IL-6, while MdMs also released IL-1β, TNF-α and IL-10, but not IL-12. The release of cytokines by infected cells was modulated by IL-17 treatment. Infected MdMs, but not infected epithelial cells displayed an altered surface phenotype: CD14, CD40 and CD54 were up-regulated, whereas MHC class I and II, and CD45 were down-regulated. Medium derived from infected epithelial cells modulated surface profile of MdMs in a different manner: MHC class I and II, and CD91 were up-regulated, while CD14 and CD45 were down-regulated. IFN-γ plays a key role in controlling chlamydial growth through induction of indoleamine 2,3-dioxygenase (IDO). A549 cells were found not to control chlamydial growth although they inducibly expressed IDO mRNA. The expression of Suppressor of Cytokine Signalling 3 (SOCS3) was investigated and A549 cells constitutively expressed both SOCS3 mRNA and protein, while HEp-2 cells expressed only SOCS3 mRNA. SOCS3 expression was further up-regulated by infection in both cells. IFN-γ treatment of A549 cells did not up-regulate SOCS3 mRNA expression, but did so in HEp-2 cells. The intracellular mechanisms of inhibition of IFN-γ-mediated chlamydial control in these cells remained unclear and require further study. The findings presented in this thesis are discussed in relation to a hypothesis that early immune responses of infected lung cells play a crucial role in the outcome of the infection and that they contribute to the establishment of persistence.

description: Utilizing all the experimental measured charmless $B \to PP$, $PV$ decay modes, where $P(V)$ denotes a light pseudoscalar (vector) meson, we extract the CKM angle $γ$ by global fit. All the unknown hadronic parameters are fitted with $γ$ together from experimental data, so as to make the approach least model dependent. The different contributions for various decay modes are classified by topological weak Feynman diagram amplitudes, which are to be determined by the global fit. To improve the precision of this approach, we consider flavor SU(3) breaking effects of topological diagram amplitudes among different decay modes by including the form factors and decay constants. The fitted result for CKM angle $γ$ is $(69.8 \pm 2.1 \pm 0.9) ^{\degree}$. It is consistent with the current world average with a better precision.
