description: A series of 353 red electronic spectra obtained between 1994 and 2010, and of 171 UBV photometric observations of the 2010 eclipse, were analyzed in an effort to better understand the eclipsing binary eps Aur. The main results follow. (1) We attempted to recover a spectrum of the companion by disentangling the observed spectra of the eps Aur binary failed, but we were able to disentangle the spectrum of telluric lines and obtain a mean spectrum of the F-type primary star. The latter was then compared to a grid of synthetic spectra for a number of plausible values of T(eff) and log(g), but a reasonably good match was not found. However, we conclude that the observed spectrum is that of a low-gravity star. (2) We examined changes in the complex H-alpha line profiles over the past 16 years, with particular emphasis on the 2009-2011 eclipse period, by subtracting a mean out-of-eclipse H-alpha profile (appropriately shifted in radial velocity) from the observed spectra. We find that the dark disk around the unseen companion has an extended 'atmosphere' that manifests itself via blueshifted and redshifted H-alpha 'shell' absorptions seen projected against the F star. Significantly, the H-alpha shell line first appeared three years before first contact of the optical eclipse when the system was not far past maximum separation. (3) Analyses of radial velocities and central intensities of several strong, unblended spectral lines, as well as UBV photometry, demonstrated that these observables showed apparent multiperiodic variability during eclipse. The dominant period of 66.21 was common to all the observables, but with different phase shifts between these variables. This result strongly supports our earlier suggestion that the photometric variability seen during eclipse is intrinsic to the F star, and therefore, the idea of a central brightening due to a hole in the disk should be abandoned.

description: COVID-19 has important implications for European solidarity. In this study, it is proposed to consider the role of information and media use for citizens’ attitudes towards European solidarity given the accelerated information supply alongside an increase in information-seeking behaviour among citizens. These factors have previously received little attention in the extant literature. In particular, we examine three dimensions of transnational solidarity (fiscal, medical and border solidarity) and present results from a four-wave panel survey conducted in the Netherlands between April and July 2020. It will be shown that solidarity support changes as the pandemic unfolds. Variation in general media use is only marginally related to solidarity, possibly due to an increase in media use during the pandemic. Yet, there are some effects at the media outlet level, particularly for newspaper reading. This research note highlights important implications for future research on European solidarity during and in the aftermath of crises.

description: This article investigates the ‘conflict parabola’ of the negotiations between EU member states during the COVID-19 pandemic. The crisis reopened the foundational controversy over cross-national solidarity under economic adversities. After a peak of conflict in March–April 2020, the political climate gradually shifted from antagonism to appeasement, creating the conditions necessary for the adoption of the Next Generation EU plan. Building on the negative experiences of past crises, some EU leaders engaged in a strategy of ‘polity maintenance’, i.e. keeping the EU polity together, regardless of interest-based divisions. This strategy mainly rested on public communication. The article documents both conflict and appeasement by analysing a corpus of leaders’ quotes drawn from the press (covering eight countries) and a corpus of speeches by Angela Merkel. The Chancellor made a high political investment in EU polity maintenance, presenting European cohesion as part and parcel of Germany’s national interest.

description: ABSTRACT: This study investigates human exposure to per- andpolyfluoroalkyl substances (PFAS) via drinking water and evaluateshuman health risks. An analytical method for 56 target PFAS,including ultrashort-chain (C2−C3) and branched isomers, wasdeveloped. The limit of detection (LOD) ranged from 0.009 to 0.1ng/L, except for trifluoroacetic-acid and perfluoropropanoic-acidwith higher LODs of 35 and 0.24 ng/L, respectively. The methodwas applied to raw and produced drinking water from 18 Dutchlocations, including groundwater or surface water as source, andapplied various treatment processes. Ultrashort-chain (300 to 1100ng/L) followed by the group of perfluoroalkyl-carboxylic-acids(PFCA, ≥C4) (0.4 to 95.1 ng/L) were dominant. PFCA and perfluoroalkyl-sulfonic-acid (≥C4), including precursors, showedsignificantly higher levels in drinking water produced from surface water. However, no significant difference was found for ultrashortPFAS, indicating the need for groundwater protection. Negative removal of PFAS occasionally observed for advanced treatmentindicates desorption and/or degradation of precursors. The proportion of branched isomers was higher in raw and produceddrinking water as compared to industrial production. Drinking water produced from surface water, except for a few locations, exceednon-binding provisional guideline values proposed; however, all produced drinking waters met the recent soon-to-be bindingdrinking-water-directive requirements.
Transport moments beyond the leading order

Subjects: subject: 530 Physik

description: For chaotic cavities with scattering leads attached, transport properties can be approximated in terms of the classical trajectories which enter and exit the system. With a semiclassical treatment involving fine correlations between such trajectories we develop a diagrammatic technique to calculate the moments of various transport quantities. Namely, we find the moments of the transmission and reflection eigenvalues for systems with and without time reversal symmetry. We also derive related quantities involving an energy dependence: the moments of the Wigner delay times and the density of states of chaotic Andreev billiards, where we find that the gap in the density persists when subleading corrections are included. Finally, we show how to adapt our techniques tonon-linear statistics by calculating the correlation between transport moments. In each setting, the answer for the $n$-th moment is obtained for arbitrary $n$ (in the form of a moment generating function) and for up to the three leading orders in terms of the inverse channel number. Our results suggest patterns which should hold for further corrections and by matching with the low order moments available from random matrix theory we derive likely higher order generating functions.

description: Since the beginning of the COVID-19 epidemic, governments across Europe have attempted to prevent the spread of the disease by limiting the movement of their citizens. In this article, we analyse whether the level of compliance with social distancing measures is associated with political, economic, and demographic factors. In particular, our interests lie in two areas. First, as lockdowns have dragged on, many countries see some political resistance, often, though not always, from populist movements: are localities that support populist movements more likely to ignore social distancing measures? Secondly, economic security: do localities with higher levels of income and wealth have higher levels of social distancing? We combine anonymised movement data from people’s mobile phones drawn from the Google Community Mobility surveys with subnational economic and demographic data to answer these questions. It is found that across Europe, social distancing patterns correlate strongly with populist attitudes and economic security.

Bladder and bowel dysfunction in children : an investigation of cardiac autonomic nervous system activity and related therapies
Creators: name: Fazeli, Mir Sohail
Publisher: name: University of British Columbia
Year: 2017

description: Bladder and bowel dysfunction (BBD) consists of a prevalent group of conditions presenting mainly with lower urinary tract symptoms. The autonomic nervous system (ANS), comprising mainly of the sympathetic (SNS) and parasympathetic nervous systems (PNS), regulates lower urinary tract function. ANS role in the pathogenesis of BBD in not known. BBD management initiates with education and life-style modification (standard urotherapy or SU). Additionally, adjunctive treatments may be administered. Current treatments are often partially effective, costly, and sometimes associated with side-effects. The overall goal of this dissertation was to describe cardiac ANS activity in children with BBD before receiving any treatments and subsequently after current and proposed adjunctive therapies. Study 1: Forty children with BBD were compared with nineteen healthy controls for the activity of ANS measured via spectral analysis of heart rate variability (HRV). Results demonstrated a significantly lower overall ANS and PNS activity at baseline in BBD group. Study 2: The efficacy of pelvic floor biofeedback in children with BBD was assessed via a systematic literature review and meta-analysis of randomized controlled trials (RCT) which showed no improvement in resolution of urinary incontinence after 6 months of biofeedback compared to other adjunctive treatments. Study 3: Ten children from Study 1 with overactive bladder (OAB) were followed receiving antimuscarinics for approximately 3 months. Results showed a significant reduction in the PNS activity after treatment accompanied by a failure to achieve complete symptom resolution. Study 4: Twenty-three children with BBD were randomized to SU plus diaphragmatic breathing (DB) or SU only in a pilot trial. Results showed a low overall feasibility for proposing DB in controlling symptoms mainly due to low adherence during an approximately 3 months of follow-up. Positive correlations were found between number of DB practices and change from baseline in overall ANS and PNS activity. In summary, BBD was associated with a significantly low overall ANS and PNS activity. There is lack of evidence supporting relative treatment efficacy of biofeedback. Use of antimuscarinics in OAB was associated with further reduction in cardiac PNS activity and the pilot study showed low overall feasibility for proposing DB for three months.

description: The littlest Higgs model with T-parity (LHT) has new flavor-changing (FC) couplings with the Standard Model (SM) quarks, which do not suffer strong constraints from electroweak precision data. So these FC interactions may enhance the cross sections of some flavor-changing neutral-current (FCNC) processes. In this work, we study the FC top-charm associated productions via $e^{-}γ$ collision at the ILC. We find that the cross sections are sensitive to the mirror quark masses. With reasonable values of the parameters, the cross sections may reach the detectable level and provide useful information about the relevant parameters in the LHT model, especially setting an upper limit on the mirror quark masses.

Our results show that Fermi liquid behavior is not confined to the edge of the superconducting dome and is robust up to at least T_c^{max}/3.5. Superconductivity is found to survive up to a larger doping p_c = 0.31 than in La_{2-x}Sr_xCuO_4. Our data imply that electronic inhomogeneity does not play a significant role in the loss of superconductivity and superfluid density in overdoped cuprates, and point towards a purely magnetic or electronic pairing mechanism

description: In order to halt the spread of COVID-19 governments have engaged in policies that are both economically costly and involve infringements of individual rights. In democratic countries, these policy responses have elicited significant debate but little is known about the extent to which the responses are supported or opposed by the broader public. This article investigates how citizens across eight Western democracies evaluate the specific policies imposed by their governments to contain the COVID-19 pandemic. The study relies on large-scale, longitudinal surveys that are reflective of the national populations (total N = 124,062). On this basis, it is investigated how pandemic-specific and broader political attitudes correlate with support for government responses during a significant part of 2020, a period marked by pandemic restrictions in all the countries. Medium to high levels of support for the government’s responses are found in all eight countries. Beyond the regular voters of the government, support is driven by individuals high in interpersonal trust and self-assessed knowledge about COVID-19. This may suggest that halting the spread of COVID-19 is viewed as a collective action problem and mobilises support from those who know how to act and who trust others to act similarly.

description: A model of Yang-Mills interactions and gravity in terms of the Clifford algebra Cl(0,6) is presented. The gravity and Yang-Mills actions are formulated as different order terms in a generalized action. The feebleness of gravity as well as the smallness of the cosmological constant and theta terms are discussed at the classical level. The invariance groups, including the de Sitter and the Pati-Salam SU(4) subgroups, consist of gauge transformations from either side of an algebraic spinor. Upon symmetry breaking via the Higgs fields, the remaining symmetries are the Lorentz SO(1,3), color SU(3), electromagnetic U(1)_EM, and an additional U(1). The first generation leptons and quarks are identified with even and odd parts of spinor idempotent projections. There are still several shortcomings with the current model. Further research is needed to fully recover the standard model results.

title: Rudolph Otto's theory of religious experience in The Idea of the Holy : A study in the phenomenology and philosophy of religion
Creators: name: Schlamm, L. P
Publisher: name: University of Kent
Year: 1988

description: This essay seeks to chart a largely unexplored psychology of religious experience in The Idea of the Holy, which is directly related to Otto's claim that one of the most important functions of discourse about religious experience is to evoke numinous feelings in a religiously sensitive audience. It will be demonstrated that Otto's concepts of schematization of the numinous, the numinous and the rational a priori, and divination cannot be understood by phenomenologists and philosophers of religion except in the light of this claim, and that Otto intends that his concept of schematization (profoundly influenced by Fries's transcendental idealism) be identified with his law of association of analogous feelings which explains how the excitation of numinous experience is produced. Moreover, this theory of religious experience rests upon an assumption about the relationship between religious language and experience which requires elucidation and evaluation. Otto's claims about numinous experience being inexpressible and yet, paradoxically, made intelligible through the use of analogy will be critically examined in the light of recent philosophical discussion concerning the relationship between all language and experience, and it will be shown not only that Otto's ineffability language is not unintelligible, but also that he offers a sophisticated theory of analogical language which may do much to extend the boundaries of our understanding of religious experience. Furthermore, an assessment will be made of the cognitive status of numinous experience; and it will be argued that, in spite of Otto's failure to establish its cognitive certainty by appealing to his account of the numinous a priori, he successfully demonstrates that, whatever its cognitive status-may be, it is a distinctive experience which cannot be confused with any other and is easily identifiable as unmistakably religious. Finally, an attempt will be made to clarify Otto's standing within the history of phenomenology of religion.

description: Direct oral anticoagulants (DOAC) off-label use data is lacking. Our study aimed to assess the clinical outcomes in a racially mixed population treated for atrial fibrillation (AF) and venous thromboembolism (VTE). We retrospectively evaluated six months of DOAC prescriptions for AF or VTE treatment. Prescriptions were classified as off-label or appropriate following FDA labeling. The off-label group was sub-classified as under or overdosing. Of the 1,087 DOAC prescriptions, 67% were for AF. African Americans and Caucasians were equally represented. There were 171 (16%) inappropriate prescriptions, with 106 (62%), being underdosed. The off-label group had a higher 30-day readmissions risk (OR = 1.69, 95% CI:1.11–2.54, p = 0.012) and 1-year all-cause mortality (OR = 1.90, 95% CI:1.02–3.37, p = 0.032). There was no difference in major bleeding (OR = 1.27, 95% CI:0.63–2.37, p = 0.480) or new thromboembolism (OR = 1.27, 95% CI:0.73–2.13, p = 0.369) between the groups. Underdosing carried a higher risk of new thromboembolism (OR = 3.15, 95% CI:1.09–9.15, p = 0.024). One in every six patients received off-label DOACs dosing. Off-label use had increased 30-day readmissions and 1-year all-cause mortality. Underdosing was associated with a higher risk of new thromboembolism.

description: The study of twisted representations of graded vertex algebras is important for understanding orbifold models in conformal field theory. In this paper we consider the general set-up of a vertex algebra $V$, graded by $\G/\Z$ for some subgroup $\G$ of $\R$ containing $\Z$, and with a Hamiltonian operator $H$ having real (but not necessarily integer) eigenvalues. We construct the directed system of twisted level $p$ Zhu algebras $\zhu_{p, \G}(V)$, and we prove the following theorems: For each $p$ there is a bijection between the irreducible $\zhu_{p, \G}(V)$-modules and the irreducible $\G$-twisted positive energy $V$-modules, and $V$ is $(\G, H)$-rational if and only if all its Zhu algebras $\zhu_{p, \G}(V)$ are finite dimensional and semisimple. The main novelty is the removal of the assumption of integer eigenvalues for $H$. We provide an explicit description of the level $p$ Zhu algebras of a universal enveloping vertex algebra, in particular of the Virasoro vertex algebra $\vir^c$ and the universal affine Kac-Moody vertex algebra $V^k(\g)$ at non-critical level. We also compute the inverse limits of these directed systems of algebras.

description: Nationwide lockdowns implemented by governments to confront the COVID-19 pandemic came at a high economic price. The article investigates citizens’ evaluation of the trade-off between public health measures and their economic consequences. Using a vignette experiment conducted in June 2020 on 7,500 respondents in seven European countries the article tests whether perceived threats of the health and economic consequences of the COVID-19 pandemic affect citizens’ preferences for strict or mild lockdown measures. Findings show that European citizens tend to prefer strict measures protecting public health despite their damage to the economy. Even individuals more concerned about the pandemic’s economic impact do not prefer milder restrictions. Sociodemographic factors only indirectly affect public preferences, through perceived threats. Additionally, findings show that trust in experts and political orientations matter. These results resonate with previous research showing that public opinion in hard times is likely to be guided by risk perceptions and subjective attitudes.

Licking River Basin in Kentucky

description: Abstract:
Nearly 9,600 miles of streams flow through the Licking River Basin's 3,700 square miles in 22 counties. From a hill in southern Magoffin County 1,600 feet above sea level, the Licking River runs northwest down to the Ohio River at 448 feet above sea level.
The underlying rocks in the basin are, in general, dominated by shale. This creates a large number of perennial streams in the basin and provides a foundation for ponds and lakes, but also limits the potential for water wells. There are 29,000 acres of wetland in the basin.
Residents draw about 24 million gallons of water per day (mgd) from streams and reservoirs in the basin. On average, about 2,770 mgd flow into the Ohio, but about once every 10 years, only 2 mgd will flow at the mouth for a week. This variability in flow affects water users and stream life.
More than 550 miles of assessed streams in the basin do not support designated uses for warm-water aquatic habitat or primary contact recreation. Not all streams have been assessed. The percentage of assessed streams not supporting uses was: warm-water aquatic habitat (45%); primary contact recreation (68%). Nearly 100 miles of streams have been declared special use waters: either, cold water aquatic habitat, exceptional waters, reference reach waters, or outstanding state resource waters.
There are five remediation priority watersheds including 430 square miles: primary impacts are pathogens, nutrients, and siltation.
There are many communities just outside the perimeter of the Basin that discharge treated wastewater into the basin, and may impact the Basin in other ways. For this reason, they are shown on the map.

The origin of these instabilities is revisited in the framework of the nuclear energy density functional theory and a simple prescription is proposed to remove them. The stability of several Skyrme parametrizations is reexamined.

description: A sensor membrane has been developed for the determination of copper(II) ions that displays excellent performance due to internal referencing of luminescence intensities. The applied sensing scheme (dual lifetime referencing) makes use of the indicator lucifer yellow (LY) and an inert reference luminophore (a ruthenium complex entrapped in polyacrylonitrile beads). Both are contained in a hydrogel matrix. The copper-dependent fluorescence intensity change of LY can be converted in either a phase shift or time dependent parameter. The sensing membrane is capable of determining copper(II) with an outstanding high selectivity over a dynamic range between 1 and 1000µM in neutral or weekly acidic conditions. The advantages of the referencing method over intensity based measurementswas demonstrated by the measurement of turbid solutions. The scheme was also applied to two-dimensional measurements in the time domain. Sensor integrated microtiterplates were imaged with a CCD camera gated with square pulses in the microsecond range

description: A comparative study on the effect of different immobilization methods and matrix materials on the performance of copper(II)-sensitive membrane layers is presented. The indicator dye Zincon was immobilized in hydrophilic and hydrophobic polymers by various methods including: (a) physical entrapment of the Zincon-tetraoctylammonium ion pair in plasticized PVC, hydrogel, polystyrene, ethyl cellulose, poly-HEMA, AQ-polymer and in sol–gel glass; (b) electrostatic immobilization on an anion exchanger cellulose; and (c) covalent immobilization on cellulose via a sulfatoethylsulfonyl reactive group. The response to copper(II) ion was evaluated kinetically via the initial slope of the change in absorbance within 1 min. Layers made of hydrogel and PVC provide the highest sensitivity, while covalent immobilization is the most reproducible one, and sol–gel layers display the best mechanical stability.

In our research we propose and test an assessment tool able to reveal main environmental and non-formal learning indicators in tourism-education-recreation activities, regarding visitors’ opinions. This tool can be used by practitioners, farm managers and other stakeholders, to assess their activities. Also, the tool can help Multifunctional Farms, to find their niche market, profiles of future visitors. This tool covers a huge gap between theory and practice of Multifunctional Agriculture, the tourism-recreation-education activities.

description: A reservoir type of capillary microsensor for pCO2 measurements is presented. The sensor is based on the measurement of the fluorescence intensity of the anionic form of the pH indicator 1-hydroxy-3,6,8-pyrenetrisulfonate in the form of its ion pair with a quaternary ammonium base in an ethyl cellulose matrix. The glass capillary containing the reservoir sensor was prepared by immersing the tip of the optical fiber into the sensing agent very close to the sensor tip thus providing a very small volume for the sensing reaction. The purpose of the sensing approach is to regenerate the dye/buffer system by diffusion, which may be poisoned by interfering acids, or bleach by photolysis. The fresh cocktail from the reservoir takes the place of protonated form of the dye. The internal buffer system also makes the protonation-deprotonation equilibria reversible. The distal tip of the internal buffer containing reservoir is coated with a gas-permeable but ion-impermeable teflon membrane. The dynamic range for the detection of pCO2 is between 1 and 20 hPa, which corresponds to the range of dissolved CO2 in water. The response time is 15 s and the detection limit is 1 hPa of pCO2. The recovery performance of this sensor can be improved by means of mechanical adjustment of the sensor tip in a micrometric scale.

description: We report spectroscopic observations with the Gemini South Telescope of 5 faint V~20 RR Lyrae stars associated with the Pisces overdensity. At a heliocentric and galactocentric distance of ~80 kpc, this is the most distant substructure in the Galactic halo known to date. We combined our observations with literature data and confirmed that the substructure is composed of two different kinematic groups. The main group contains 8 stars and has = 50 km/s, while the second group contains four stars at a velocity of = -52 km/s, where V_{gsr} is the radial velocity in the galactocentric standard of rest. The metallicity distribution of RR Lyrae stars in the Pisces overdensity is centered on [Fe/H]=-1.5 dex and has a width of 0.3 dex. The new data allowed us to establish that both groups are spatially extended making it very unlikely that they are bound systems, and are more likely to be debris of a tidally disrupted galaxy or galaxies. Due to small sky coverage, it is still unclear whether these groups have the same or different progenitors.

description: Two pivotal, randomized, double-blind studies in a chronic dermatology disease were ongoing when the COVID-19 pandemic broke out. The trials had identical design, with four parallel treatment arms: two doses of active drug, an active comparator and placebo. When recruitment was temporarily halted due to the pandemic, both trials had already achieved over 80% of the targeted sample size. The unprecedented and unpredictable dynamic of the pandemic caused concerns about potential risks to data integrity and interpretability, which needed to be addressed. In this article, we describe some of these challenges and mitigation strategies. In particular, the complex confirmatory situation involving multiple active doses, endpoints and comparators led to a careful modification of the testing scheme to maintain the power of key endpoints and comparisons while still controlling the relevant Type I error rates. Specifically, the strategy was adjusted to perform some lower-level statistical tests in the hierarchy on the pool of both studies, taking advantage of the replicate study design. Primary endpoint comparisons against placebo and active control remained separately by study. In this article, we share our ideas and experiences in devising this risk mitigation proposal for the statistical methodology of these pivotal trials during the COVID-19 pandemic.

description: In a first course of general relativity it is usually quite difficult for students to grasp the concept of a geodesic. It is supposed to be straight (auto-parallel) and yet it 'looks' curved. In these situations it is very useful to have some explicit examples available which show the different behaviour of geodesics. In this paper we present the GeodesicViewer, an interactive tool for studying the behaviour of geodesics in many different space-times. The geodesics can be represented in several ways, depending on the space-time in question. The use of a local reference frame and 'Cartesian-like' coordinates helps the students to develop some intuition in various situations. We present the various features of the GeodesicViewer in the form of readily formulated exercises for the students.

description: A new architecture is presented for a Networked Signal Processing System (NSPS) suitable for handling the real-time signal processing of multi-element radio telescopes. In this system, a multi-element radio telescope is viewed as an application of a multi-sensor, data fusion problem which can be decomposed into a general set of computing and network components for which a practical and scalable architecture is enabled by current technology. The need for such a system arose in the context of an ongoing program for reconfiguring the Ooty Radio Telescope (ORT) as a programmable 264-element array, which will enable several new observing capabilities for large scale surveys on this mature telescope. For this application, it is necessary to manage, route and combine large volumes of data whose real-time collation requires large I/O bandwidths to be sustained. Since these are general requirements of many multi-sensor fusion applications, we first describe the basic architecture of the NSPS in terms of a Fusion Tree before elaborating on its application for the ORT. The paper addresses issues relating to high speed distributed data acquisition, Field Programmable Gate Array (FPGA) based peer-to-peer networks supporting significant on-the fly processing while routing, and providing a last mile interface to a typical commodity network like Gigabit Ethernet. The system is fundamentally a pair of two co-operative networks, among which one is part of a commodity high performance computer cluster and the other is based on Commercial-Off The-Shelf (COTS) technology with support from software/firmware components in the public domain.

description: Clinical trials of a vaccine during an epidemic face particular challenges, such as the pressure to identify an effective vaccine quickly to control the epidemic, and the effect that time-space-varying infection incidence has on the power of a trial. We illustrate how the operating characteristics of different trial design elements may be evaluated using a network epidemic and trial simulation model, based on COVID-19 and individually randomized two-arm trials with a binary outcome. We show that “ring” recruitment strategies, prioritizing participants at an imminent risk of infection, can result in substantial improvement in terms of power in the model we present. In addition, we introduce a novel method to make more efficient use of the data from the earliest cases of infection observed in the trial, whose infection may have been too early to be vaccine-preventable. Finally, we compare several methods of response-adaptive randomization (RAR), discussing their advantages and disadvantages in the context of our model and identifying particular adaptation strategies that preserve power and estimation properties, while slightly reducing the number of infections, given an effective vaccine.

description: We investigate the evolution of solitary waves in a nonlocal medium in the presence of disorder. By using a perturbational approach, we show that an increasing degree of nonlocality may largely hamper the Brownian motion of self-trapped wave-packets. The result is valid for any kind of nonlocality and in the presence of non-paraxial effects. Analytical predictions are compared with numerical simulations based on stochastic partial differential equation
