description: This paper presents a qualitative study to explore how individuals perceive and verify visual digital certificates with QR codes. During the COVID-19 pandemic, such certificates have been used in the EU to provide standardized proof of vaccination. We conducted semi-structured interviews with N=17 participants responsible for verifying COVID-19 certificates as part of their job. Using a two-fold thematic analysis approach, we, among other things, identified and classified multiple behavioral patterns, including inadequate reliance on visual cues as a proxy for proper digital verification. We present design and structural recommendations based on our findings, including conceptual changes and improvements to storage and verification apps to limit shortcut opportunities. Our empirical findings are hence essential to improve the usability, robustness, and effectiveness of visual digital certificates and their verification.

description: We present the numu to nue appearance and the numu disappearance results, using a total of 1.43 x 10^{20} protons on target collected with the T2K experiment. T2K is long baseline neutrino experiment in Japan with detectors located at J-PARC, Tokai, and at Kamioka in the Gifu Prefecture, situated 295 km away from J-PARC. The muon neutrino beam is produced and measured at the near detectors at J-PARC whilst the neutrino rates after oscillation are measured with the Super-Kamiokande detector, at Kamioka. A total of six events pass all the selection criteria for numu to nue oscillations at the far detector Super-Kamiokande, leading to 0.03(0.04) < sin^2 2theta_{13} < 0.28(0.34) for deltaCP = 0 and normal (inverted) hierarchy at 90% C.L. The numu disappearance analysis excludes no oscillations at 4.3 sigma. At 90% C.L., the best fit values are sin^2 2theta_{23} > 0.84 and 2.1 x 10^{-3} < Delta m^2_{23} (eV^2) < 3.1 x 10^{-3}. Finally, we present an overview of the T2K plans from 2011 onwards.

description: Deepfakes pose severe threats of visual misinformation to our society. One representative deepfake application is face manipulation that modifies a victim’s facial attributes in an image, e.g., changing her age or hair color. The state-of-the-art face manipulation techniques rely on Generative Adversarial Networks (GANs). In this paper, we propose the first defense system, namely UnGANable, against GAN-inversionbased face manipulation. In specific, UnGANable focuses on defending GAN inversion, an essential step for face manipulation. Its core technique is to search for alternative images (called cloaked images) around the original images (called target images) in image space. When posted online, these cloaked images can jeopardize the GAN inversion process. We consider two state-of-the-art inversion techniques including optimization-based inversion and hybrid inversion, and design five different defenses under five scenarios depending on the defender’s background knowledge. Extensive experiments on four popular GAN models trained on two benchmark face datasets show that UnGANable achieves remarkable effectiveness and utility performance, and outperforms multiple baseline methods. We further investigate four adaptive adversaries to bypass UnGANable and show that some of them are slightly effective.

description: A partial wave analysis of pbar-p -> eta-eta-pizero data from the Crystal Barrel experiment is made in terms of s-channel resonances. The decay channels a_0(980)-eta, f_0(1770)-pi and f_0(2105)-pi provide evidence for two I = 1 J^{PC} = 0^{-+} resonances. The first has mass M =2360 +- 25 MeV and width Gamma = 300^{+100}_{-50} MeV, and the second M =2070 \pm 35 MeV, Gamma = 310^{+100}_{-50} MeV. There is also evidence for a J^{PC} = 2^{-+} state with M = 2005 +- 15 MeV and Gamma = 200 +- 40 MeV, decaying strongly to a_0(980)-pi.

title: Strong words, weak subjects: a critical examination and theoretical and historical contextualisation of the novels of Don Delillo
Creators: name: Thomas, J
Publisher: name: Bath Spa University
Year: 2001

description: This thesis is a theory focused critical contextualisation of the novels of Don DeLillo that situates the author at the forefront of contemporary literatures of resistance. Through a detailed examination of a number of his works, and a generic discussion of all, it makes the argument that, by foregrounding a number of radical aesthetic methodologies such as controlled monologism and what Fredric Jameson terms 'the transcoding of perceptual terminologies' - or the emplacement of multiple theoretical positions within the totality of the novel - DeLillo attempts to compel his reader into coming to terms with their linguistically circumscribed personal ontology. The first, introductory chapter, an analysis of the writer's depictions of the social environment of contemporary America and his metatheoretical solutions to what cultural commentator Jean Baudrillard calls 'hyperreality' - the hegemonic prevalence of serial signs and simulations that self-reproduce and separate humanity from the 'real' world - sets up the proposition that DeLillo's ambivalent attitude to language, his representations of subjects struggling to find their own voice and name, is connected to a politically motivated aesthetic that provides the reader with a kind of 'cognitive mapping,' enabling them to contextualise themselves within the confusing spatial and temporal dimensions of the late-capitalist postmodern world. The propositions introduced in chapter one are then built upon in three wholly original close-readings of some of DeLillo's best known works. Chapter two examines DeLillo's controversial metafictional historiography Libra through the critical lens of the sublime and Jean-Francois Lyotard's binary of the discursive and figural - discussing how DeLillo's Oswald is constructed within the text in order to connect with Lyotard's ideas on postmodern representation. This is followed in chapter three by a Bakhtinian reading of DeLillo's early work Ratner's Star that clarifies the process of cognitive mapping, and an ecocritical analysis of Underworld in chapter four that consolidates and expands the drive of the thesis. The thesis will conclude by offering a final chapter that summarises DeLillo's methodology and opens the argument out to include parallels between DeLillo's practice and that of comparable European metatheorists.

description: Publishing trajectory data (individual’s movement information) is very useful, but it also raises privacy concerns. To handle the privacy concern, in this paper, we apply differential privacy, the standard technique for data privacy, together with Markov chain model, to generate synthetic trajectories. We notice that existing studies all use Markov chain model and thus propose a framework to analyze the usage of the Markov chain model in this problem. Based on the analysis, we come up with an effective algorithm PrivTrace that uses the first-order and second-order Markov model adaptively. We evaluate PrivTrace and existing methods on synthetic and real-world datasets to demonstrate the superiority of our method.

description: We present an overview of the initial results from the Chandra Planetary Nebula Survey (ChanPlaNS), the first systematic (volume-limited) Chandra X-ray Observatory survey of planetary nebulae (PNe) in the solar neighborhood. The first phase of ChanPlaNS targeted 21 mostly high-excitation PNe within ~1.5 kpc of Earth, yielding 4 detections of diffuse X-ray emission and 9 detections of X-ray-luminous point sources at the central stars (CSPNe) of these objects. Combining these results with those obtained from Chandra archival data for all (14) other PNe within ~1.5 kpc that have been observed to date, we find an overall X-ray detection rate of ~70%. Roughly 50% of the PNe observed by Chandra harbor X-ray-luminous CSPNe, while soft, diffuse X-ray emission tracing shocks formed by energetic wind collisions is detected in ~30%; five objects display both diffuse and point-like emission components. The presence of X-ray sources appears correlated with PN density structure, in that molecule-poor, elliptical nebulae are more likely to display X-ray emission (either point-like or diffuse) than molecule-rich, bipolar or Ring-like nebulae. All but one of the X-ray point sources detected at CSPNe display X-ray spectra that are harder than expected from hot (~100 kK) central star photospheres, possibly indicating a high frequency of binary companions to CSPNe. Other potential explanations include self-shocking winds or PN mass fallback. Most PNe detected as diffuse X-ray sources are elliptical nebulae that display a nested shell/halo structure and bright ansae; the diffuse X-ray emission regions are confined within inner, sharp-rimmed shells. All sample PNe that display diffuse X-ray emission have inner shell dynamical ages

title: Persephone unbound: the natural environment, human well-being and gender, explored in selected texts, 1775-1900
Creators: name: Hunt, S
Publisher: name: Bath Spa University
Year: 2002

description: With reference to Wordsworth's suggestion that the 'love of nature' leads to the 'love of man', this thesis examines claims that a sympathetic engagement with the natural world can contribute to human well-being and social progress. It considers how such claims might be substantiated by surveying a range of literary representations of the natural world between 1775 and 1900. Categories of human well-being are explored in three contexts: valuing and accessing the countryside, botany and attitudes to animals. These accounts are focused in discussions of literary encounters with particular genera: mid-Victorian seaweed collecting and the satirical treatment of the great apes. The ecocritical groundwork of Bate and Kroeber is extended to examine a range of non-canonical texts that confirm and complement, but also occasionally contend, the Wordsworthian approach. Particular attention is paid to the ways in which the human negotiation with the living world is complicated by gender identity. Gender affects access to the countryside and determines the public context in which knowledge about the natural world is represented and shared. However, this thesis offers a contributionist literary history in which an interest in other species has advanced women's social status in terms of mobility, education and opportunities to participate in science and politics. This work takes its theoretical impetus from environmentalist and feminist cultural theories. The ideas of thinkers such as Murray Bookchin, on social ecology, and Freya Mathews, on the ecological self, have been particularly influential. The present analysis concludes in the belief that, in challenging the gendered hierarchy in the self-other opposition, such ideas represent a sophisticated continuation of the Romantic critique of the problematic relationship to the natural environment that exists in capitalist society. In so doing, ecocritical approaches make for a fruitful reconsideration of Romantic and Victorian nature literature.

description: Разработаны математические модели одно- и многоконтурных магнитных цепей электромагнитных преобразователей расхода с кольцевым каналом с учетом распределённости параметров магнитной цепи и потоков рассеяния, замыкающихся через нерабочие воздушные зазоры. Показана возможность компенсации разности магнитных сопротивлений коаксиально расположенных концентрических ферромагнитных сердечников из-за разности их длины окружности подбором толщины сердечников. Установлено, что магнитный поток в концентрических ферромагнитных сердечниках распределен по угловой координате нелинейно, а магнитная индукция в кольцевом канале неравномерно распределен по угловой и радиальной координатам. Выявлено, что с увеличением значения коэффициента затухания магнитного поля в магнитопроводе степень неравномерности магнитной индукции в кольцевом канале по угловой координате возрастает, а по радиальной координате она остается постоянной.
Emergence of a common energy scale close to the orbital-selective Mott transition

description: We calculate the spectra and spin susceptibilities of a Hubbard model with two bands having different bandwidths but the same on-site interaction, with parameters close to the orbital-selective Mott transition, using dynamical mean-field theory. If the Hund's rule coupling is sufficiently strong, one common energy scale emerges which characterizes both the location of kinks in the self-energy and extrema of the diagonal spin susceptibilities. A physical explanation of this energy scale is derived from a Kondo-type model. We infer that for multi-band systems local spin dynamics rather than spectral functions determine the location of kinks in the effective band structure.

SandDriller: A Fully-Automated Approach for Testing Language-Based JavaScript Sandboxes
Creators: name: Alhamdan, Abdullah
name: Staicu, Cristian-Alexandru
Publisher: name: CISPA
Year: 2023

description: Language-based isolation offers a cheap way to restrict the privileges of untrusted code. Previous work proposes a plethora of such techniques for isolating JavaScript code on the client-side, enabling the creation of web mashups. While these solutions are mostly out of fashion among practitioners, there is a growing trend to use analogous techniques for JavaScript code running outside of the browser, e.g., for protecting against supply chain attacks on the server-side. Irrespective of the use case, bugs in the implementation of language-based isolation can have devastating consequences. Hence, we propose SandDriller, the first dynamic analysis-based approach for detecting sandbox escape vulnerabilities. Our core insight is to design testing oracles based on two main objectives of language-based sandboxes: Prevent writes outside the sandbox and restrict access to privileged operations. Using instrumentation, we interpose oracle checks on all the references exchanged between the host and the guest code to detect foreign references that allow the guest code to escape the sandbox. If at run time, a foreign reference is detected by an oracle, SandDriller proceeds to synthesize an exploit for it. We apply our approach to six sandbox systems and find eight unique zero-day sandbox breakout vulnerabilities and two crashes. We believe that SandDriller can be integrated in the development process of sandboxes to detect security vulnerabilities in the pre-release phase.
Extended Hell(o): A Comprehensive Large-Scale Study on Email Confidentiality and Integrity Mechanisms in the Wild

description: The core specifications of electronic mail as used today date back as early as the 1970s. At that time, security did not play a significant role in developing communication protocols. These shortcomings still manifest themselves today in the prevalence of phishing and the reliance on opportunistic encryption. Besides STARTTLS, various mechanisms such as SPF, DKIM, DMARC, DANE, and MTA-STS have been proposed. However, related work has shown that not all providers support them and that misconfigurations are common. In this work, we provide a comprehensive overview of the current state of email confidentiality and integrity measures, as well as the effectiveness of their deployment. On a positive note, support for incoming TLS connections has significantly increased over the years, with over 96% of reachable MXs in the top 10 million domains allowing for explicit TLS. Notably, 30% of presented certificates are invalid, though, with the majority of issues related to the presented hostnames. In light of this, all 47 providers we tested connect to hosts with expired, self-signed, non-matching certificates, making it trivial for attackers to intercept their connections. Our analysis also shows that still only around 40% of sites specify SPF, and even high-ranked providers like t-online.de do not enforce it. Similarly, while DNS lookups are performed for both DKIM and DANE, neither mechanism is validated or enforced by all providers. In addition, we show that MTA-STS is only slowly getting traction (six providers support it) and provide the first large-scale analysis into OPENPGPKEY and SMIMEA records. All in all, this still paints a grim yet slightly improving picture for the state of email security by late 2022.

description: Potential users of Safe and Sustainable by Design (SSbD) approaches, in particular small and medium sized enterprises, struggle to find their way in the sheer amount of existing knowledge, testing methods and tools. To better guide them in making decisions throughout their entire design process of advanced nanomaterials, a user-friendly online intelligent SSbD Decision Support System (DSS) is developed within the HARMLESS project. Previous experience and stakeholder analysis is used to integrate existing as well as numerous newly generated NAM-based data & models and integrated approaches to testing and assessment (IATAs) into a unified HARMLESS SSbD framework. We propose a modular approach in which all data, knowledge and models are captured in stand-alone, interconnected FAIR components. HARMLESS will A) use eNanoMapper as a database to store experimental data, B) launch a new FAIR Data Point to capture all knowledge and decision rules, C) launch a novel Model FAIRpoint with runnable algorithms and D) launch a new Decision Support System interface. The DSS interface connects to the HARMLESS FAIR components, but can also connect to external components (e.g. NanoCommons Data Warehouse, Jaqpot, NanoInformaTIX). The decision support process is based on a well-established concept of Risk Informed Decision Making adopted by NASA and US NRC, based on the fusion of deterministic and probabilistic risk assessment. To this end, Bayesian network modelling is used to integrate existing and new knowledge, data and models into an integrative reasoning model that captures uncertainty. This information is presented in an interactive visualization presenting an overview of all important decision criteria augmented with SSbD advice allowing the user to interactively work with the tool to improve their design.

Heterogeneous reactions of NO₃ and N₂O₅ with organic substrates of atmospheric relevance
Creators: name: Xiao, Song
Publisher: name: University of British Columbia
Year: 2011

description: Atmospheric heterogeneous reaction could modify the physical properties and chemical composition of aerosol particles, thereby affecting their roles in climate, air pollution, and human health. The current knowledge of heterogeneous reactions between nighttime gas-phase oxidants and organic aerosols is very limited. The goal of this thesis was to contribute to the understanding of such reactions, particularly to the kinetics of NO₃ and N₂O₅ reactions with a variety of organic substrates and mixtures that can serve as proxies for aerosol particles. In the first series of studies, we investigated the reactive uptake of NO₃ with binary organic mixtures of an unsaturated organic (methyl oleate) and saturated molecules as “matrix molecules”. For liquid mixtures, the uptake coefficients (γ) of the matrices were significantly increased with the addition of small amounts of methyl oleate. The increase can vary by a factor of 5 depending on the type of matrix used. For solid-liquid mixtures, the uptake coefficient decreased by a factor of 10 after exposure to NO₃ for 90 minutes. For all liquid mixtures, the atmospheric lifetime was estimated on the order of a few minutes (with an upper limit of 35 mins), whereas, for liquid-solid mixtures, a lower limit to the lifetime was estimated to be 1-2 hours. In the second series of studies, we investigated NO₃ uptake on solid tridecanal and the uptake on liquid binary mixtures containing tridecanal and saturated organics as matrices. Uptake on the solid tridecanal was shown to be efficient, with γ = (1.6 ± 0.8) ×10–². For liquid binary mixtures, the uptake coefficient also depended on the matrix molecule. The atmospheric lifetime of aldehydes was estimated to range from 1.9–7.5 h due to NO₃ oxidation. In the third series of studies, we investigated the N₂O₅ uptake kinetics on alcohols. The uptake coefficients of N₂O₅ for five different alcohols at 293 K varied by 2 orders of magnitude, ranging from 3×10–⁴ to 1.8×10–². The atmospheric lifetime of alcohols was calculated to range from 0.6–130 h, depending on the physical and chemical properties of the organic liquid.

description: The CDF collaboration has reported a 4.1σ excess in their lepton, missing energy, and dijets channel. This excess, which takes the form of an approximately Gaussian peak centered at a dijet invariant mass of 147 GeV, has provoked a great deal of experimental and theoretical interest. Although the DØ collaboration has reported that they do not observe a signal consistent with CDF, there is currently no widely accepted explanation for the discrepancy between these two experiments. A resolution of this issue is of great importance---not least because it may teach us lessons relevant for future searches at the LHC---and it will clearly require additional information. In this paper, we consider the ability of the Tevatron and LHC detectors to observe evidence associated with the CDF excess in a variety of channels. We also discuss the ability of selected kinematic distributions to distinguish between Standard Model explanations of the observed excess and various new physics scenarios.

description: Bibliography: p. 132-150
description: The purpose of this study was to compare symptoms of emotional disorder, low self-esteem, conduct disorder, and attention deficit/hyperactivity disorder (ADHD) across weight groups classified as normal weight, overweight, and obese. Data on 2394 12 to 15 year olds were obtained from the National Longitudinal Survey of Children and Youth, Cycle 3. Multivariate analysis of variance and follow up analyses indicated that obese males reported significantly more emotional disorder symptoms, while obese males and females both reported lower levels of self-esteem that their non-obese peers. Chi-square analysis indicated that clinically significant symptoms of emotional disorder, low self-esteem, and ADHD were significantly more prevalent in the obese adolescents than their non-obese peers. Finally, regression analysis revealed that ADHD symptoms accounted for more variance in symptoms of emotional disorder and low self-esteem in the obese group than in the non-obese group.

description: Multiple Acts of Identification among Educators in a Post-Conflict Situation: Evidence from Kosovo draws upon the personal and interpretive journeys of Kosovar Albanian and Kosovar Serb educators. This study examined the possibility that multiple acts of identification not only exist but contribute to the future of democratization in education. Inquiring into the lived experiences of educators in Kosovo, examining how multiple acts of identification contribute to the understanding of identity formation within intricate political and social situations, and understanding how these processes of identity formation interweave with both individual and collective associations have been the primai-y objectives of this study. This study concludes that Kosovar, as a civic identification, encompasses but does not supplant other acts of identification and advances democratic dispositions in both the political and social realm.

description: We report a superconducting artificial atom with an observed quantum coherence time of T2*=95us and energy relaxation time T1=70us. The system consists of a single Josephson junction transmon qubit embedded in an otherwise empty copper waveguide cavity whose lowest eigenmode is dispersively coupled to the qubit transition. We attribute the factor of four increase in the coherence quality factor relative to previous reports to device modifications aimed at reducing qubit dephasing from residual cavity photons. This simple device holds great promise as a robust and easily produced artificial quantum system whose intrinsic coherence properties are sufficient to allow tests of quantum error correction.

description: Differential Power Analysis (DPA) measures single-bit differences between data values used in computer systems by statistical analysis of power traces. In this paper, we show that the mere co-location of data values, e.g., attacker and victim data in the same buffers and caches, leads to power leakage in modern CPUs that depends on a combination of both values, resulting in a novel attack, Collide+Power. We systematically analyze the power leakage of the CPU's memory hierarchy to derive precise leakage models enabling practical end-to-end attacks. These attacks can be conducted in software with any signal related to power consumption, e.g., power consumption interfaces or throttling-induced timing variations. Leakage due to throttling requires 133.3 times more samples than direct power measurements. We develop a novel differential measurement technique amplifying the exploitable leakage by a factor of 8.778 on average, compared to a straightforward DPA approach. We demonstrate that Collide+Power leaks single-bit differences from the CPU's memory hierarchy with fewer than 23000 measurements. Collide+Power varies attacker-controlled data in our end-to-end DPA attacks. We present a Meltdown-style attack, leaking from attacker-chosen memory locations, and a faster MDS-style attack, which leaks 4.82 bit/h. Collide+Power is a generic attack applicable to any modern CPU, arbitrary memory locations, and victim applications and data. However, the Meltdown-style attack is not yet practical, as it is limited by the state of the art of prefetching victim data into the cache, leading to an unrealistic real-world attack runtime with throttling of more than a year for a single bit. Given the different variants and potentially more practical prefetching methods, we consider Collide+Power a relevant threat that is challenging to mitigate.

description: Изучен процесс получения известково-аммиачной селитры (ИАС) на основе смешения плава нитрата аммония (NH4NO3) с известняком Карманинского месторождения. При этом массовое соотношением NH4NO3 : СаСO3 варьировали от 100 : 5 до 100 : 80. Для них определены состав, прочность, слёживаемость, пористость, впитываемость дизельного топлива, гигроскопические точки, сорбционная влагоёмкость и скорость растворения гранул. Любое количество известняковой муки резко снижает слеживаемость, пористость, впитываемость дизельного топлива, повышает прочность и скорость растворения гранул селитры. Результаты сорбционной влагоемкости гранул ИАС показывают, что оба образца при содержании в них влаги 5-6% не теряют свою первоначальную рассыпчатость. Следует отметить, что чистая АС при достижении ею количества сорбированной влаги в 3,5% начинает слёживаться, теряя при этом свою рассыпчатость. Поэтому для хранения удобрения на основе АС нужно их затаривать в бумажные или полиэтиленовые мешки.

description: We examine the structure and the evolution of Ge islands epitaxially grown on vicinal Si(111) surfaces by scanning tunneling microscopy. Contrary to what is observed on the singular surface, three-dimensional Ge nanoislands form directly through the elastic relaxation of step-edge protrusions during the unstable step-flow growth. As the substrate misorientation is increased, the islands undergo a shape transformation which is driven by surface energy minimization and controlled by the miscut angle. Using finite element simulations, we show that the dynamics of islanding observed in the experiment results from the anisotropy of the strain relaxation.

description: We present the first formal analysis and comparison of the security of the two most widely deployed exposure notification systems, ROBERT and the Google and Apple Exposure Notification (GAEN) framework. ROBERT is the most popular instalment of the centralised approach to exposure notification, in which the risk score is computed by a central server. GAEN, in contrast, follows the decentralised approach, where the user's phone calculates the risk. The relative merits of centralised and decentralised systems have proven to be a controversial question. The majority of the previous analyses have focused on the privacy implications of these systems, ours is the first formal analysis to evaluate the security of the deployed systems---the absence of false risk alerts. We model the French deployment of ROBERT and the most widely deployed GAEN variant, Germany's Corona-Warn-App. We isolate the precise conditions under which these systems prevent false alerts. We determine exactly how an adversary can subvert the system via network and Bluetooth sniffing, database leakage or the compromise of phones, back-end systems and health authorities. We also investigate the security of the original specification of the DP3T protocol, in order to identify gaps between the proposed scheme and its ultimate deployment. We find a total of 27 attack patterns, including many that distinguish the centralised from the decentralised approach, as well as attacks on the authorisation procedure that differentiate all three protocols. Our results suggest that ROBERT's centralised design is more vulnerable against both opportunistic and highly resourced attackers trying to perform mass-notification attacks.

description: Prototype pollution is a dangerous vulnerability affecting prototype-based languages like JavaScript and the Node.js platform. It refers to the ability of an attacker to inject properties into an object's root prototype at runtime and subsequently trigger the execution of legitimate code gadgets that access these properties on the object's prototype, leading to attacks such as Denial of Service (DoS), privilege escalation, and Remote Code Execution (RCE). While there is anecdotal evidence that prototype pollution leads to RCE, current research does not tackle the challenge of gadget detection, thus only showing feasibility of DoS attacks, mainly against Node.js libraries. In this paper, we set out to study the problem in a holistic way, from the detection of prototype pollution to detection of gadgets, with the ambitious goal of finding end-to-end exploits beyond DoS, in full-fledged Node.js applications. We build the first multi-staged framework that uses multi-label static taint analysis to identify prototype pollution in Node.js libraries and applications, as well as a hybrid approach to detect universal gadgets, notably, by analyzing the Node.js source code. We implement our framework on top of GitHub's static analysis framework CodeQL to find 11 universal gadgets in core Node.js APIs, leading to code execution. Furthermore, we use our methodology in a study of 15 popular Node.js applications to identify prototype pollutions and gadgets. We manually exploit eight RCE vulnerabilities in three high-profile applications such as NPM CLI, Parse Server, and Rocket.Chat. Our results provide alarming evidence that prototype pollution in combination with powerful universal gadgets lead to RCE in Node.js.

 Österreich, Kärnten: Pörtschach am Wörther See, Uferstraße, Haus Nr. 13 (ca. 0,4 km östl. der Autobahnauffahrt nach Villach), Wiese im Hausgarten, 7. 4. 2007, leg. Uhlemann (Hb. DR, WU). Taraxacum amaurolepis besitzt schwarzgrüne Hüllen und schmale, unberandete, zurückgerichtete äußere Involukralblätter, rosafarbene Blattstiele und große, z.T. mehrfach gezähnte Blattendlappen.
 Insbesondere die dunklen Hüllen weisen auf eine Verwandtschaft mit T. oblongatum (vgl. unten) hin, dem es auch – oberflächlich betrachtet – ähnelt, sich von diesem aber durch weniger stark gebogene Blattseitenlappen unterscheidet. Im Gegensatz zu T. oblongatum (s. u.) gehört T. amaurolepis zu den weniger bekannten Arten dieser Sektion und dürfte wohl deswegen in Mitteleuropa bislang auch nur sehr selten beobachtet worden sein. Ein gegenwärtig bekanntes Häufungszentrum liegt im Stadtgebiet von Dresden (Deutschland).

Synthesis and properties of gold(I) and Ruthenium(II) complexes of beta-substituted oligothiophenes

description: Oligothiophenes functionalized in the beta-position with ethynyl and aryl phosphine groups (57 – 59) are reported. Compounds 57 and 59 are used as bridging ligands with Au(I) (80 – 82, 93 – 95), while compounds 57 and 58 are used as tridentate ligands with Ru(II) (104 – 112). The optical and electronic properties of these compounds were studied with absorption and emission spectroscopy, transient absorption spectroscopy, X-ray crystallography, and electrochemistry. The lowest energy absorption bands and emission bands were found to be sensitive to the substituent and conjugation. The lowest energy pi-based absorption band in complex 80 was blue-shifted, while complexes 93 – 95 and 104 – 112 caused a bathochromic shift in the comparable band. Complexes 80, 93 and 94 showed ligand based emission at 295 K, complex 95 at temperatures <185 K, and complexes 104 – 112 were nonemissive. Complex 109 showed a transient absorption at 475 nm with a liftetime of ~100 ns. Grinding a solid state sample elicited changes in absorption and emission of powders of 57 and 80. Grinding powdered 57 caused a temporary emission and absorption band hypsochromically shifted from the unground material, whereas grinding 80 caused a bathochromic shift of the absorption bands and strong emission. These results were attributed to changes in conformation of the terthiophene backbone. Crystal structures of 80, 81, 93 – 95, 105, 109 and 110 gave insight into the ligand binding and conjugation along the terthiophene backbone. Sterically bulky substituents increased the torsion angle between adjacent thienyl units in 57 relative to 59; 80 and 82 relative to 57; and 93 and 94 relative to 59. Solid state structures of complexes 80, 81, and 93 – 95 showed the ligand bridged two Au(I) centres, while structures of 105, 109 and 110 showed 57 binding as a tridentate ligand. The cyclic voltammograms of 57 – 59, 93 – 95, and 104 – 112 were obtained. Compounds 59 and 93 – 95 electrochemically polymerize. Complex 95 and poly-95 have Au(I/II) oxidation waves. Complexes 104 – 110 and 112 also have metal-based oxidation waves. The Ru(II/III) oxidation waves of 104 – 110 were used to determine the ligand electrochemical parameter of 57.

description: The recently discovered shear modulus anomaly in solid 4He bears a strong similarity to the phenomenon of supersolidity in solid 4He and can lead to the period shift and dissipative signals in torsional oscillator experiments that are nearly identical to the classic NCRI signals observed by Kim and Chan. In the experiments described here, we attempt to isolate the effects of these two phenomena on the resonance periods of torsion oscillators. We have constructed a triple compound oscillator with distinct normal modes. We are able to demonstrate that, for this oscillator, the period shifts observed below 200 mK have their primary origin in the temperature dependence of the shear modulus of the solid 4He sample rather than the formation of a supersolid state.

description: In the absence of a half-bound state, a compactly supported potential of a Schrödinger operator on the line is determined up to a translation by the zeros and poles of the meropmorphically continued left (or right) reflection coefficient. The poles are the eigenvalues and resonances, while the zeros also are physically relevant. We prove that all compactly supported potentials (without half-bound states) that have reflection coefficients whose zeros and poles are $\eps$-close in some disk centered at the origin are also close (in a suitable sense). In addition, we prove stability of small perturbations of the zero potential (which has a half-bound state) from only the eigenvalues and resonances of the perturbation.

description: Neural networks show a progressive increase in complexity during the time course of evolution. From diffuse nerve nets in Cnidaria to modular, hierarchical systems in macaque and humans, there is a gradual shift from simple processes involving a limited amount of tasks and modalities to complex functional and behavioral processing integrating different kinds of information from highly specialized tissue. However, studies in a range of species suggest that fundamental similarities, in spatial and topological features as well as in developmental mechanisms for network formation, are retained across evolution. 'Small-world' topology and highly connected regions (hubs) are prevalent across the evolutionary scale, ensuring efficient processing and resilience to internal (e.g. lesions) and external (e.g. environment) changes. Furthermore, in most species, even the establishment of hubs, long-range connections linking distant components, and a modular organization, relies on similar mechanisms. In conclusion, evolutionary divergence leads to greater complexity while following essential developmental constraints.
