Subjects: subject: Nuclear Theory (nucl-th)

description: Three-body nuclear reactions in two-nucleon plus core systems are described in the framework of exact scattering equations including the core excitation. A nucleon-core optical potential is constructed that can be easily adjusted to the reference potential and thereby to the experimental two-body data, if available. This constitutes an important improvement over the simple deformation of the potential used previously that violated the original fit to the data. Predictions for elastic, inelastic, and transfer reactions involving $^{10}{Be}$ and $^{24}{Mg}$ nuclear cores are obtained. The new optical potential leads to a moderate increase of cross sections.

description: We study the motion of test particles in the gravitational field of a Schwarzschild black hole surrounded by a spherical dark matter cloud with non-zero tangential pressure and compute the luminosity of the accretion disk. The presence of non vanishing tangential pressures allows to mimic the dark matter's angular momentum while still considering a static model, which simplifies the mathematical framework. We compare the numerical results about the influence of dark matter on the luminosity of accretion disks around static supermassive black holes with the previously studied cases of isotropic and anisotropic pressures. We show that the flux and luminosity of the accretion disk in the presence of dark matter are different from the case of a Schwarzschild black hole in vacuum and highlight the impact of the presence of tangential pressures.

description: We experimentally show an all-optical multipolar decomposition of the lowest-order Eigenmodes of a single gold nanoprism using azimuthally and radially polarized cylindrical vector beams. By scanning the particle through these tailored field distributions, the multipolar character of the Eigenmodes gets encoded into 2D-scanning intensity maps even for higher-order contributions to the Eigenmode that are too weak to be discerned in the direct far-field scattering response. This method enables a detailed optical mode analysis of individual nanoparticles.

description: Background: Despite the development of safe and effective vaccines, effective treatments for COVID-19 disease are still urgently needed. Several antiviral drugs have shown to be effective in reducing progression of COVID-19 disease. Methods: In the present work, we use an agent-based mathematical model to assess the potential population impact of the use of antiviral treatments in four countries with different demographic structure and current levels of vaccination coverage: Kenya, Mexico, United States (US) and Belgium. We analyzed antiviral effects on reducing hospitalization and death, and potential antiviral effects on reducing transmission. For each country, we varied daily treatment initiation rate (DTIR) and antiviral effect in reducing transmission (AVT). Results: Irrespective of location and AVT, widespread antiviral treatment of symptomatic adult infections (20% DTIR) prevented the majority of COVID-19 deaths, and recruiting 6% of all adult symptomatic infections daily reduced mortality by over 20% in all countries. Furthermore, our model projected that targeting antiviral treatment to the oldest age group (65 years old and older, DTIR of 20%) can prevent over 30% of deaths. Our results suggest that early antiviral treatment (as soon as possible after inception of infection) is needed to mitigate transmission, preventing 50% more infections compared to late treatment (started 3 to 5 days after symptoms onset). Our results highlight the synergistic effect of vaccination and antiviral treatment: as the vaccination rate increases, antivirals have a larger relative impact on population transmission. Finally, our model projects that even in highly vaccinated populations, adding antiviral treatment can be extremely helpful to mitigate COVID-19 deaths. Conclusions: These results suggest that antiviral treatments can become a strategic tool that, in combination with vaccination, can significantly reduce COVID-19 hospitalizations and deaths and can help control SARS-CoV-2 transmission.

description: Despite intense experimental efforts, the nature of the unconventional superconducting order parameter of UTe$_2$ remains elusive. This puzzle stems from different reported numbers of superconducting transitions at ambient pressure, as well as a complex pressure-temperature phase diagram. To bring new insights into the superconducting properties of UTe$_2$, we measured the heat capacity and electrical resistivity of single crystals under compressive uniaxial stress $σ$ applied along different crystallographic directions. We find that the critical temperature $T_{\rm c}$ of the single observed bulk superconducting transition decreases with $σ$ along $[100]$ and $[110]$ but increases with $σ$ along $[001]$. Aside from its effect on $T_{\rm c}$, we notice that $c$-axis stress leads to a significant piezoresistivity, which we associate with the shift of the zero-pressure resistivity peak at $T^\star \approx 15\, \rm K$ to lower temperatures under stress. Finally, we show that an in-plane shear stress $σ_{xy}$ does not induce any observable splitting of the superconducting transition over a stress range of $σ_{xy}\approx 0.17 \, \rm GPa$. This result suggests that the superconducting order parameter of UTe$_2$ may be single-component at ambient pressure.

description: NaTiSi2O6 is an exemplary compound, showing an orbital assisted spin-Peierls phase transition at Tc = 210 K. We present the results of 29Si and 23Na NMR measurements of NaTiSi2O6. The use of magic angle spinning techniques unambiguously shows that only one dynamically averaged silicon site can be seen at T > Tc. At cooling, the 29Si MAS NMR spectrum shows interesting changes. Immediately below Tc the spectrum gets very broad. Cooling further, it shows two broad lines of unequal intensities which become narrower as the temperature decreases. Below 70 K two narrow lines have chemical shifts that are typical for diamagnetic silicates. The hyperfine field values for the two sites are 7.4 kOe/kB and 4.9 kOe/kB. In the paramagnetic state at high temperature, the spin-lattice relaxation of 29Si was found to be weakly temperature dependent. Below Tc the Arrhenius type temperature dependence of the relaxation rate indicates an energy gap D/kB = 1000(50) K. In the temperature region from 120 to 300 K the relaxation rate was strongly frequency dependent. At room temperature we found a power law dependence on Larmor frequency of -0.65(5). For 70 < T < 120 K the relaxation appeared to be non-exponential which we assigned to a relaxation due to fixed paramagnetic centers. Simulation of the magnetization recovery curve showed a temperature dependence of the concentration of these centers proportional to the magnetic susceptibility. The NMR spectrum of 23Na shows the line with typical shape for the central transition of a quadrupolar nucleus. A small frequency shift of 23Na resonance corresponds to a very small hyperfine field of 0.32 kOe/kB . In addition, at T > Tc the 23Na spectrum shows another Lorentzian shaped resonance which we attribute to the Na sites where the quadrupolar coupling is partly averaged out by ionic motion.

description: The purpose of this study is to consider the determinants of World Wide Web (WWW) usage
using clickstream data. Clickstream data is a natural byproduct of a user accessing WWW pages, and
refers to the sequence of pages visited and the time these pages were viewed. A key component of this
study is a large scale empirical analysis of clickstream data from a representative sample of PC owning
households in the U.S. This sample comes from Media Metrix's PC Meter using a nationwide panel of
over 5,000 households during 1997 and 1998. A primary finding of this research is that demographics
are not a primary driver of web usage. While it is true that access to the WWW is influenced by
demographic characteristics, the best way to predict current usage is to use information about past usage,
and not use demographics. Additionally, we show there is a great deal of diversity in the usage of
individual sites. These findings imply that if managers really want to learn how to fulfill the promise of
interactivity on the WWW they need to learn how to capture and use their customers' clickstreams.

description: The dependence of the black hole (BH) shadow and thermodynamics may be structured in the regular spacetime. Taking the regular Bardeen-AdS BH as an example, the relationship between the shadow radius and the event horizon radius is derived. It is found that these two radii display a positive correlation, implying that the BH temperature can be rewritten as a function of shadow radius in the regular spacetime. By analyzing the phase transition curves under the shadow context, we found that the shadow radius can replace the event horizon radius to present the BH phase transition process, and the phase transition grade can also be revealed by the shadow radius, indicating that the shadow radius may serve as a probe for the phase structure in the regular spacetime. Utilizing the temperature-shadow radius function, the thermal profile of the Bardeen-AdS BH is established. We obtained that the temperature shows an N-type change trend in P

description: We report our experiment on sideband cooling with two Raman transitions in a $Λ$ configuration that allows selective coherent population trapping (CPT) of the motional ground state. The cooling method is applied to $^{87}$Rb atoms in a circularly-polarized one-dimensional optical lattice. Owing to the vector polarizability, the vibration frequency of a trapped atom depends on its Zeeman quantum number, and CPT resonance for a pair of bound states in the $Λ$ configuration depends on their vibrational quantum numbers. We call this scheme motion-selective coherent population trapping (MSCPT) and it is a trapped-atom analogue to the velocity-selective CPT developed for free He atoms. We observe a pronounced dip in temperature near a detuning for the Raman beams to satisfy the CPT resonance condition for the motional ground state. Although the lowest temperature we obtain is ten times the recoil limit owing to the large Lamb-Dicke parameter of 2.3 in our apparatus, the experiment demonstrates that MSCPT enhances the effectiveness of Raman sideband cooling and enlarges the range of its application. Discussions on design parameters optimized for MSCPT on $^{87}$Rb atoms and opportunities provided by diatomic polar molecules, whose Stark shift shows strong dependence on the rotational quantum number, are included.

Jihadist suicide: a moral ideal

description: Many analysts mistake suicide bombing as a "natural" consequence of political grievance: as the ultimate in the politics of despair, citing the plight of Palestinians as the central case study. My contention is that the suicide-murder doctrine had its genesis in Revolutionary Iran and became institutionalised during the war years with Iraq (1980-1988). The ideology that supported suicide on the battlefield is identical to that of the suicide terrorist globally. The training of insurgents outside of Iran - including Hezbollah in Lebanon, the Tamil Tigers in Sri Lanka, Hamas and the Palestinian Islamic Jihad, and the al Qaeda global network - ensured the development of the phenomenon best termed Jihadist Suicide. Putting this phenotnenon into a sociological and historical context, this work draws on comparative and ethnographic techniques to analyse significant concepts - like suicide, martyrdom, secularisation and ideology - to identify the nuances of Jihadist Suicide. It is argued that in the history of ethnic conflict, this form of suicide has been rare.Tradition does not support acts of such suicide - not even in its political or religious guise as martyrdom. Historically, it never occurred as a globalised phenomenon. Rather, it is a product of late modernity, whereby a world driven by ontological insecurity and uncertainty has opened the way for political elites and counter-elites to introduce radical ideas. It is not deviant behaviour, as is the common perception of suicide, but a moral ideal.

description: The purpose of this paper is to study some properties of solutions to one dimensional as well as multidimensional stochastic differential equations (SDEs in short) with super-linear growth conditions on the coefficients. Taking inspiration from \cite{BEHP, KBahlali, Bahlali}, we introduce a new {\it{local condition}} which ensures the pathwise uniqueness, as well as the non-contact property. We moreover show that the solution produces a stochastic flow of continuous maps and satisfies a large deviations principle of Freidlin-Wentzell type. Our conditions on the coefficients go beyond the existing ones in the literature. For instance, the coefficients are not assumed uniformly continuous and therefore can not satisfy the classical Osgood condition. The drift coefficient could not be locally monotone and the diffusion is neither locally Lipschitz nor uniformly elliptic. Our conditions on the coefficients are, in some sense, near the best possible. Our results are sharp and mainly based on Gronwall lemma and the localization of the time parameter in concatenated intervals

description: We calculate the baryon factorial cumulants assuming arbitrary short-range correlations and the global baryon number conservation. The general factorial cumulant generating function is derived. Various relations between factorial cumulants subjected to baryon number conservation and the factorial cumulants without this constraint are presented. We observe that for $n$-th factorial cumulant, the short-range correlations of more than $n$ particles are suppressed with the increasing number of particles. The recently published [1] relations between the cumulants in a finite acceptance with global baryon conservation and the grand-canonical susceptibilities are reproduced.

Ωστόσο, όταν αυτά εντάσσονται σε μεταλλικά πλαίσια δημιουργούν ένα νέο δομοστατικό μικτό σύστημα πλαίσιο-τοίχωμα (μεταλλικό ή σύμμικτο) κατ’ αντιστοιχία με τα ομοειδή συστήματα από οπλισμένο σκυρόδεμα. Ουσιαστικά, η εμφάτνωση του μεταλλικού ή σύμμικτου τοιχείου εντός του μεταλλικού πλαισίου δημιουργεί ένα φέροντα οργανισμό ο οποίος συνδυάζει τα πλεονεκτήματα των δύο ανεξάρτητων συστημάτων και αλληλοαναιρεί τα μειονεκτήματα αυτών.

Τα μεταλλικά τοιχεία ως δομοστατικό σύστημα ικανοποιούν τις βασικές απαιτήσεις του αντισεισμικού σχεδιασμού εξασφαλίζοντας δυσκαμψία-αντοχή-πλαστιμότητα, ενώ παράλληλα ανάλογα με την μόρφωση του συστήματος είναι δυνατό να επιτευχθεί αυξημένη ενεργειακή απόσβεση της εισαγόμενης ενέργειας (π.χ. χρήση χάλυβα χαμηλής διαρροής 80-230 MPa, σύστημα τοιχείου αποσβεστήρα).

Ways of improving the management of environmental risks

subject: FOS: Economics and business

description: From the public's discovery of environmental quality in the late 1960s to the present, there has been increasing recognition that a more systematic approach is required to manage risks and to achieve the gains at low cost. Such a systematic approach must begin with risk identification, then go on to risk assessment, consideration of management options, a decision analysis of the options, and an examination of strategies for reducing loss. One of the most difficult aspects of environmental risk management is setting goals. There is a tendency to engage in rhetoric about zero risks and a pristine environment. However, moving toward more realistic goals requires consideration of what is an acceptable risk level. This level cannot be defined without knowing the benefits that come with the risk and the costs of reducing the risk. More generally, the criteria for selecting a risk management strategy include the residual level of risk, efficiency in reducing risk, equity, administrative simplicity, and public acceptability. A number of frameworks are currently used by U.S. regulatory agencies to manage risk: no-risk, risk-risk, technology-based standards, risk-benefit, cost-effectiveness, regulatory budget, and benefit-cost analysis. In specifying that an agency must use one of these frameworks, the U.S. Congress is implicitly specifying the goals for risk reduction. It appears to be easier for the U.S. Congress to specify a framework than a goal. Some of the nonregulatory means of managing risk include the market, and legal mechanisms. These risk management institutions have been effective and are a necessary part of any risk management program.

description: One of the pleasures of preparing an essay in Gottfried Haberler's honor comes from rereading some of his past contributions. The two quotations at the start of this essay, although written a generation apart, are as relevant to current discussions of European monetary union and policy coordination as they were to the subjects addressed at the time they were written. The first quotation, criticizing early postwar proponents of a world central bank, reminds us that gains from a common currency—whether for Europe or all the world's open economies—depend on the policy rule adopted by the proposed monetary authority. A policy rule that avoids both inflation and deflation increases welfare; rules, procedures, or discretionary actions that produce price instability do not. This applies equally if the actions are coordinated. Indeed, coordination that produces inflation in all leading countries is clearly worse than uncoordinated policies that leave one or more countries pursuing price stability. The second quotation takes a balanced view of fixed and fluctuating exchange rates. Fixed rates can, in principle, increase welfare. Whether they do so in practice depends on the policies followed by the central banks and governments.
Values and green politics: a rhetorical interpretation of the role of values in green political processes
Creators: name: Tenbensel, Timothy
Publisher: name: The Australian National University
Year: 1994
Subjects: subject: Green movement Australia
subject: Values Australia

description: This thesis explores the role of values in the conduct of green politics. In political science and sociology this topic is most commonly addressed in terms of theoretical approaches that aim to identify green politics in terms of a distinct set of values. Such approaches attribute the emergence and growth of green politics to value change. I argue that this conventional wisdom is based on a misunderstanding of the significance of values in political processes. One consequence of this misunderstanding is that a number of typical issues that face green political organisations are not adequately addressed. In particular, attempts to identify green politics in terms of values disregard the ambiguity that is a central feature of normative political discourse. In this thesis I develop an alternative approach which considers values as a type of good reason which is deployed in the context of rhetorical argument. In doing so, I investigate the relationship between values and other types of rhetorical reasoning. Green politics is a type of politics in which normative reasons are characteristically privileged in political discourse. I refer to this rhetorical privileging as 'value primacy'. The second part of the thesis examines the consequences of value primacy for green political action taking as a case study a series of discussions among Australian green activists. These greens were engaged in drawing up structures and mechanisms for political co-operation with a view to forming a political party or network. This case study demonstrates the various ways in which values are used rhetorically in the practice of green politics. In particular, it reveals a great deal of ambiguity and flexibility in the conduct of normative discourse among greens. I also explore some of the perverse effects that follow from attempts to implement green political values in the light such ambiguity. Many of the problems identified in the Australian example can be generalised to the experiences of other green political organisations. This exploration of the perverse effects of green normative rationality suggests that the emphasis that both academic analysts and green activists place upon value change and conversion as a way of understanding green politics is unwarranted.

An estimator of $β$ is proposed, based on Gini's rank association coefficient $G(\underline y;b)$ and defined as $\tildeβ = \frac 12 \, \left\{ \sup (b: G(\underline y;b) >0) + \right. $ $ \left. \inf (b: G(\underline y;b) <0) \right\}.$ The properties of $\tildeβ$ and of the related confidence interval are studied. Some comparisons are given, in terms of asymptotic relative efficiency, with other estimators of $β$ including that obtained with the method of least squares.

description: COVID-19-associated coagulopathy (CAC) is a life-threatening complication of SARS-CoV-2 infection. However, the underlying cellular and molecular mechanisms driving this condition are unclear. Evidence supports the concept that CAC involves complex interactions between the innate immune response, the coagulation and fibrinolytic pathways, and the vascular endothelium, resulting in a procoagulant condition. Understanding of the pathogenesis of this condition at the genomic, molecular and cellular levels is needed in order to mitigate thrombosis formation in at-risk patients. In this Perspective, we categorize our current understanding of CAC into three main pathological mechanisms: first, vascular endothelial cell dysfunction; second, a hyper-inflammatory immune response; and last, hypercoagulability. Furthermore, we pose key questions and identify research gaps that need to be addressed to better understand CAC, facilitate improved diagnostics and aid in therapeutic development. Finally, we consider the suitability of different animal models to study CAC.

The photo-production of \jpsi mesons at low transverse momentum is studied in peripheral PbPb collisions, which confirms coherent \jpsi production in hadronic collisions. These latest results significantly improve previous measurements and are compared with some theoretical predictions.

description: We investigated the electrostatic behavior of ferroelectric liquid droplets exposed to the pyroelectric field of a lithium niobate ferroelectric crystal substrate. The ferroelectric liquid is a nematic liquid crystal in which almost complete polar ordering of the molecular dipoles generates an internal macroscopic polarization locally collinear to the mean molecular long axis. Upon entering the ferroelectric phase by reducing the temperature from the nematic phase, the liquid crystal droplets become electromechanically unstable and disintegrate by the explosive emission of fluid jets. These jets are mostly interfacial, spreading out on the substrate surface, and exhibit fractal branching out into smaller streams to eventually disrupt, forming secondary droplets. We understand this behavior as a manifestation of the Rayleigh instability of electrically charged fluid droplets, expected when the electrostatic repulsion exceeds the surface tension of the fluid. In this case the charges are due to the bulk polarization of the ferroelectric fluid which couples to the pyroelectric polarization of the underlying lithium niobate substrate through its fringing field and solid-fluid interface coupling. Since the ejection of fluid does not neutralize the droplet surfaces, they can undergo multiple explosive events as the temperature decreases.

description: People living in rural regions in the United States face more health challenges than their non-rural counterparts which could put them at additional risks during the COVID-19 pandemic. Few studies have examined if rurality is associated with additional mortality risk among those hospitalized for COVID-19. We studied a retrospective cohort of 3,991 people hospitalized with SARS-CoV-2 infections discharged between March 1 and September 30, 2020 in one of 17 hospitals in North Carolina that collaborate as a clinical data research network. Patient demographics, comorbidities, symptoms and laboratory data were examined. Logistic regression was used to evaluate associations of rurality with a composite outcome of death/hospice discharge. Comorbidities were more common in the rural patient population as were the number of comorbidities per patient. Overall, 505 patients died prior to discharge and 63 patients were discharged to hospice. Among rural patients, 16.5% died or were discharged to hospice vs. 13.3% in the urban cohort resulting in greater odds of death/hospice discharge (OR 1.3, 95% CI 1.1, 1.6). This estimate decreased minimally when adjusted for age, sex, race/ethnicity, payer, disease comorbidities, presenting oxygen levels and cytokine levels (adjusted model OR 1.2, 95% CI 1.0, 1.5). This analysis demonstrated a higher COVID-19 mortality risk among rural residents of NC. Implementing policy changes may mitigate such disparities going forward.

description: Background Diarrhoeal disease remains a leading cause of death among children mostly in low and middle- income countries. Factors contributing to disease severity are complex and there is currently no consensus on a scoring tool for use in community-based studies. Methods Data were collected during a passive surveillance system in an outpatient health facility in Lusaka, Zambia from March 2019 to July 2019. Diarrhea episodes were assessed for severity using an in-house severity scoring tool (CIDRZ) and previously published scores (Vesikari, Clark, CODA, and DHAKA). The CIDRZ score was constructed using fieldworker-reported clinical signs and exploratory factor analysis. We used precision-recall curves measuring severe diarrhoea (i.e., requiring intravenous rehydration or referred for hospital admission) to determine the best performing scores. Then, we used Cronbach's alpha to assess the scale's internal consistency. Finally, we used Cohen's kappa to assess agreement between the scores. Results Of 110 diarrhea episodes, 3 (3%) required intravenous rehydration or were referred for hospital admission. The precision-recall area under the curve of each score as a predictor of severe diarrhoea requiring intravenous rehydration or hospital admission was 0.26 for Vesikari, 0.18 for CODA, 0.24 for Clark, 0.59 for DHAKA, and 0.59 for CIDRZ. The CIDRZ scale had substantial reliability and performed similarly to the DHAKA score. Conclusions Diarrhoea severity scores focused on characteristics specific to dehydration status may better predict severe diarrhea among children in Lusaka. Aetiology-specific scoring tools may not be appropriate for use in community healthcare settings. Validation studies for the CIDRZ score in diverse settings and with larger sample sizes are warranted.

description: Almost all massive galaxies today are understood to contain supermassive black holes (SMBH) at their centers. SMBHs grew by accreting material from their surroundings, emitting X-rays as they did so. X-ray Luminosity Functions (XLFs) of Active Galactic Nuclei (AGN) have been extensively studied in order to understand the AGN population's cosmological properties and evolution. We present a new fixed rest-frame method to achieve a more accurate study of the AGN XLF evolution over cosmic time. Normally, XLFs are constructed in a fixed observer-frame energy band, which can be problematic because it probes different rest-frame energies at different redshifts. In the new method, we construct XLFs in the fixed rest-frame band instead, by varying the observed energy band with redshift. We target a rest-frame 2$-$8 keV band using XMM-Newton and HEAO 1 X-ray data, with 7 observer-frame energy bands that vary with redshift for $0 < z < 3$. We produce the XLFs using two techniques; one to construct a binned XLF, and one using a Maximum Likelihood (ML) fit, which makes use of the full unbinned source sample. We find that our ML best-fit pure luminosity evolution (PLE) results for both methods are consistent with each other, suggesting that performing XLF evolution studies with the high-redshift data limited to high-luminosity AGN is not very sensitive to the choice of fixed observer-frame or rest-frame energy band, which is consistent with our expectation that high-luminosity AGN typically show little absorption. We have demonstrated the viability of the new method in measuring the XLF evolution.

The strategies of influence: Japan's agricultural cooperatives (Nokyo) as a pressure group

description: Nokyo, Japan’s mammoth farm organisation is the subject of this thesis. The focal point of interest is Nokyo’s role as a pressure group and the relationship between this and other aspects of its diverse activities. The approach is primarily empirical: the thesis seeks to elucidate Nokyo as an organisation functioning according to its own logic. This emerges as a compound of historical, legal, administrative, economic and political factors. At the same time, broader theoretical issues are taken up including comparative references to patterns of Japanese interest group behaviour. Special attention is given to the extent of Nokyo's conservative bias and connections between Nokyo and political parties. Chapter 1 considers Nokyo's organisational structure and functions, while Chapter 2 explores Nokyo's policy-related activities in more detail. Chapter 3 examines historical aspects of Nokyo's official representation in the Diet; types of agricultural cooperative electoral participation are surveyed in Chapter 4. Chapter 5 takes up the issue of rice as the traditional focus of pressure from the agricultural cooperatives, with other commodities such as fruit and livestock products discussed in Chapter 6 in the context of the agricultural trade liberalisation debate. Throughout, Nokyo is seen as a group heavily committed to its own economic priorities, but exercising massive political clout as a result of the interaction between certain organisational attributes and external environmental factors. In policy terms, Nokyo's primary interest is in agricultural support prices. Related to this are the twin issues of rice as regulated by the Food Control system - Nokyo's chief source of official patronage - and protection of domestic farm producers from foreign competition. Japanese agriculture is seen as a highly managed and controlled industry with a substantial political content - both cause and effect of Nokyo's involvement in the policy-making process.

description: Equine recurrent uveitis (ERU) is a spontaneous, painful, and vision threatening disease affecting up to 25% of equine populations worldwide. Current treatments of ERU are nonspecific and have many side effects which limits them to short-term use. In order to develop an effective therapy for ERU, we investigated the use of adeno-associated virus (AAV) gene therapy, exploiting a natural immune tolerance mechanism induced by equine interleukin-10 (Equine-IL10). The purpose of this study was to evaluate the therapeutic efficacy of a single intravitreal (IVT) dose of AAV8-Equine-IL10 gene therapy for inhibition of experimental autoimmune uveitis (EAU) in rats. Each rat was dosed intravitreally (IVT) in both eyes with either balanced salt solution (BSS) (control; n = 4), AAV8-Equine-IL10 at a low dose (2.4x109 vg; n = 5) or high dose (2.4x1010 vg; n = 5). EAU was induced in all groups of rats 7 days after IVT injections and euthanized 21 days post-injection. Ophthalmic examination and aqueous humor (AH) cell counts were recorded with the observer blinded to the treatment groups. Histopathology and qPCR were performed on selected ocular tissues. Data presented herein demonstrate that AAV8-Equine-IL10 treated rats exhibited a significant decrease in clinical inflammatory scores and AH cell counts compared to BSS-treated EAU eyes on days 10, 12 and 14 post EAU induction at both administered vector doses. Mean cellular histologic infiltrative scores were also significantly less in AAV8-Equine-IL10 dosed rats compared to the BSS group. Intravitreal injection of AAV8-Equine-IL10 resulted in Equine-IL10 cDNA expression in the ciliary body, retina, cornea, and optic nerve in a dose-dependent manner. A single IVT injection of AAV8-Equine-IL10 appeared to be well-tolerated and inhibited EAU even at the lowest administered dose. These results demonstrate safety and efficacy of AAV8-Equine-IL10 to prevent EAU and support continued exploration of AAV gene therapy for the treatment of equine and perhaps human recurrent uveitis.

description: Reconfigurable intelligent surface (RIS) is capable of intelligently manipulating the phases of the incident electromagnetic wave to improve the wireless propagation environment between the base-station (BS) and the users. This paper addresses the joint user scheduling, RIS configuration, and BS beamforming problem in an RIS-assisted downlink network with limited pilot overhead. We show that graph neural networks (GNN) with permutation invariant and equivariant properties can be used to appropriately schedule users and to design RIS configurations to achieve high overall throughput while accounting for fairness among the users. As compared to the conventional methodology of first estimating the channels then optimizing the user schedule, RIS configuration and the beamformers, this paper shows that an optimized user schedule can be obtained directly from a very short set of pilots using a GNN, then the RIS configuration can be optimized using a second GNN, and finally the BS beamformers can be designed based on the overall effective channel. Numerical results show that the proposed approach can utilize the received pilots more efficiently than the conventional channel estimation based approach, and can generalize to systems with an arbitrary number of users.
