description: Mobile apps are increasingly created using online application generators (OAGs) that automate app development, distribution, and maintenance. These tools significantly lower the level of technical skill that is required for app development, which makes them particularly appealing to citizen developers, i.e., developers with little or no software engineering background. However, as the pervasiveness of these tools increases, so does their overall influence on the mobile ecosystem’s security, as security lapses by such generators affect thousands of generated apps. The security of such generated apps, as well as their impact on the security of the overall app ecosystem, has not yet been investigated. We present the first comprehensive classification of commonly used OAGs for Android and show how to fingerprint uniquely generated apps to link them back to their generator. We thereby quantify the market penetration of these OAGs based on a corpus of 2,291,898 free Android apps from Google Play and discover that at least 11.1% of these apps were created using OAGs. Using a combination of dynamic, static, and manual analysis, we find that the services’ app generation model is based on boilerplate code that is prone to reconfiguration attacks in 7/13 analyzed OAGs. Moreover, we show that this boilerplate code includes well-known security issues such as code injection vulnerabilities and insecure WebViews. Given the tight coupling of generated apps with their services' backends, we further identify security issues in their infrastructure. Due to the blackbox development approach, citizen developers are unaware of these hidden problems that ultimately put the end-users sensitive data and privacy at risk and violate the user’s trust assumption. A particular worrisome result of our study is that OAGs indeed have a significant amplification factor for those vulnerabilities, notably harming the health of the overall mobile app ecosystem.

Well-functioning interconnection and grid access procedures are key to ensure that the transmission system supports competition in generation and sustainable and reliable electricity supply. The ongoing transformation of the power sector is increasing the number and variety of resources seeking gird interconnection, and changing requirements and technical contributions that need to be assessed at the interconnection stage. This is leading to an evolution of these procedures in several jurisdictions, including the recent issuing of FERC Order 2023 in the USA. This panel will convey government agencies, system operators and generation agents from the USA and Latin America, to discuss: (i) challenges and recent developments on the management interconnection queues and, more broadly, of grid access processes; and (ii) what panelists have been doing to ensure that these processes enable a coordinated expansion of transmission and generation, with actions ranging from improvement of transmission planning processes to adjustment of interconnection requirements.

Offshore wind is growing worldwide, exceeding 80 GW at the end of 2023. The US has set a goal of 30 GW by 2030, and significant growth is expected beyond that. A central enabler of this growth is the onshore and offshore transmission developments necessary to bring wind energy to the loads. Because so much of this transmission must utilize submarine or underground cables in longer distance applications, HVDC technologies are of high interest. This panel will address the transmission design problem for the US East Coast, focusing on HVDC backbone topologies, converter technologies, protection, the need for standardization, integration with offshore wind farms and the onshore network, and federal, state, and local policies necessary to support this development.

description: The pressure profiles of the Intracluster Plasma in galaxy clusters show a wide variance when observed in X rays at low redshifts z<0.2. We find the profiles to follow two main patterns, featuring either a steep or a shallow shape throughout both core and outskirts. We trace these shapes back to a physical dichotomy of clusters into two classes, marked by either low entropy (LE) or high entropy (HE) throughout. From X-ray observations and Sunyaev-Zel'dovich stacked data at higher 0.20.5. We submit our physical templates and converging trend for further observational tests, in view of the current and upcoming measurements of individual, stacked, and integrated Sunyaev-Zel'dovich signals.

description: Stellar evolutionary models predict that most of the early type subdwarf stars in close binary systems have white dwarf companions. More massive companions, such as neutron stars or black holes, are also expected in some cases. The presence of compact stars in these systems can be revealed by the detection of X-rays powered by accretion of the subdwarf's stellar wind or by surface thermal emission. Using the Swift satellite, we carried out a systematic search for X-ray emission from a sample of twelve subdwarf B stars which, based on optical studies, have been suggested to have degenerate companions. None of our targets was detected, but the derived upper limits provide one of the few observational constraints on the stellar winds of early type subdwarfs. If the presence of neutron star companions is confirmed, our results constrain the mass loss rates of some of these subdwarf B stars to values <10^{-13}-10^{-12} Msun/yr.

Convergence of AI- and Physics-based Approaches in Power System Analysis, Optimization, and Control
Creators: Fangxing Li
Publisher: name: IEEE
Year: 2024

For several decades, power systems have relied on physics-based methodologies for their analysis, optimization, and control. However, the recent surge in renewable energy sources, energy storage, behind-the-meter resources combined with grid digitalization has instigated a transformative shift in the dynamics and operation of these systems. Consequently, there's a burgeoning interest in data-driven and machine learning techniques to address the escalating scale, intricacy, and unpredictability of power systems. Yet, solely relying on data-driven strategies can pose challenges related to data quality, robustness, and interpretability. Integrating both physics-based models and data-driven or AI-based methods can harness the strengths of each approach and have resulted in notable enhancements in power system analysis, optimization and control. This panel seeks to share insights and recent progresses on the amalgamation of these two methodologies with speakers from academia and industry, enabling a reliable and smooth transition from contemporary power systems to the new electric system.

description: The tensor-pomeron model is applied to low-x deep-inelastic lepton-nucleon scattering and photoproduction. We consider c.m. energies in the range 6 - 318 GeV and $Q^2 < 50 GeV^2$. In addition to the soft tensor pomeron, which has proven quite successful for the description of soft hadronic high-energy reactions, we include a hard tensor pomeron. We also include $f_2$-reggeon exchange which turns out to be particularly relevant for real-photon-proton scattering at c.m. energies in the range up to 30 GeV. The combination of these exchanges permits a description of the absorption cross sections of real and virtual photons on the proton in the same framework. In particular, a detailed comparison of this two-tensor-pomeron model with the latest HERA data for x < 0.01 is made. Our model gives a very good description of the transition from the small-$Q^2$ regime where the real or virtual photon behaves hadron-like to the large-$Q^2$ regime where hard scattering dominates. Our fit allows us, for instance, a determination of the intercepts of the hard pomeron as $1.3008(^{+73}_{-84}),$ of the soft pomeron as $1.0935(^{+76}_{-64}),$ and of the$f_2$ reggeon. We find that in photoproduction the hard pomeron does not contribute within the errors of the fit. We show that assuming a vector instead of a tensor character for the pomeron leads to the conclusion that it must decouple in real photoproduction.

description: After treating the notification of affected parties as mere side-notes in research, our community has recently put more focus on how vulnerability disclosure can be conducted at scale. The first works in this area have shown that while notifications are helpful to a significant fraction of operators, the vast majority of systems remain unpatched. In this paper, we build on these previous works, aiming to understand why the effects are not more significant. To that end, we report on a notification experiment targeting more than 24,000 domains, which allowed us to analyze what technical and human aspects are roadblocks to a successful campaign. As part of this experiment, we explored potential alternative notification channels beyond email, including social media and phone. In addition, we conducted an anonymous survey with the notified operators, investigating their perspectives on our notifications. We show the pitfalls of email-based communications, such as the impact of anti-spam filters, the lack of trust by recipients, and hesitations to fix vulnerabilities despite awareness. However, our exploration of alternative communication channels did not suggest a more promising medium. Seeing these results, we pinpoint future directions in improving security notifications.
Simulations of GRB Jets in a Stratified External Medium: Dynamics, Afterglow Lightcurves, Jet Breaks and Radio Calorimetry

description: The dynamics of GRB jets during the afterglow phase is most reliably and accurately modelled using hydrodynamic simulations. All published simulations, however, have considered only a uniform external medium, while a stratified external medium is expected around long duration GRB progenitors. Here we present simulations of the dynamics of GRB jets and the resulting afterglow emission for both uniform and stratified external media with $ρ\propto r^{-k}$ for k = 0, 1, 2. The simulations are performed in 2D using the special relativistic version of the Mezcal code. The dynamics for stratified external media are broadly similar to those derived for expansion into a uniform external medium. The jet half-opening angle start increasing logarithmically with time once the Lorentz factor drops below 1/theta_0. For larger k values the lateral expansion is faster at early times and slower at late times with the jet expansion becoming Newtonian and slowly approaching spherical symmetry over progressively longer timescales. We find that contrary to analytic expectations, there is a reasonably sharp jet break in the lightcurve for k = 2 although the shape of the break is affected more by the viewing angle than by the slope of the external density profile. Steeper density profiles are found to produce more gradual jet breaks while larger viewing angles cause smoother and later appearing jet breaks. The counter-jet becomes visible as it becomes sub-relativistic, and for k=0 this results in a clear bump-like feature in the light curve. However, for larger k values the jet decelerates more gradually, causing only a mild flattening in the radio light curve that might be hard to discern when k=2. Late time radio calorimetry is likely to consistently over-estimate the true energy by up to a factor of a few for k=2, and either over-predict or under-predict it by a smaller factor for k = 0,1.

The decarbonization agenda has prompted a global shift in the generation matrix, leading to vast integration of renewable resources. New climate patterns and their linkage to natural hazards add another layer of uncertainty that operators must handle. Despite significant changes in operational modes and increasing uncertainties, computational scheduling models remain largely unchanged. These models are pivotal in power systems, determining generation scheduling, market prices, and driving long-term investments. In this high-uncertainty environment with low variable costs, storage and flexibility become vital for system reliability and economic affordability. However, to fully harness the benefits of storage, flexibility, and renewables, computational models need to account for uncertainties and a realistic look-ahead to capture relevant system's opportunity costs. In this panel, we explore the role of uncertainty and look ahead in scheduling and pricing models for a sustainable decarbonization of power systems.

description: Transport measurements provide important characterizations of the nature of stripe order in the cuprates. Initial studies of systems such as La(1.6-x)Nd(0.4)Sr(x)CuO(4) demonstrated the strong anisotropy between in-plane and c-axis resistivities, but also suggested that stripe order results in a tendency towards insulating behavior within the planes at low temperature. More recent work on La(2-x)Ba(x)CuO(4) with x=1/8 has revealed the occurrence of quasi-two-dimensional superconductivity that onsets with spin-stripe order. The suppression of three-dimensional superconductivity indicates a frustration of the interlayer Josephson coupling, motivating a proposal that superconductivity and stripe order are intertwined in a pair-density-wave state. Complementary characterizations of the low-energy states near the Fermi level are provided by measurements of the Hall and Nernst effects, each revealing intriguing signatures of stripe correlations and ordering. We review and discuss this work.

Our panel discussion, " Economic viability of long-duration energy storage systems", delves into the critical issue of assessing the economics of long-duration energy storage (LDES). The aggressive and necessary decarbonization of power systems in several countries is going to lead to energy matrices that will mostly rely on intermittent renewables and lack firm generation. Within these circumstances, LDES is a promising solution to guarantee that customers will continue to have energy when they need it. This panel brings together experts from different institutions with a diverse background to discuss the future needs of fully decarbonized power systems, how LDES can be instrumental in fulfilling these needs, and how much LDES should cost to be an economically viable solution.

description: Many deployed learned models are black boxes: given input, returns output. Internal information about the model, such as the architecture, optimisation procedure, or training data, is not disclosed explicitly as it might contain proprietary information or make the system more vulnerable. This work shows that such attributes of neural networks can be exposed from a sequence of queries. This has multiple implications. On the one hand, our work exposes the vulnerability of black-box neural networks to different types of attacks -- we show that the revealed internal information helps generate more effective adversarial examples against the black box model. On the other hand, this technique can be used for better protection of private content from automatic recognition models using adversarial examples. Our paper suggests that it is actually hard to draw a line between white box and black box models.

Modern power systems undergo unprecedented changes, especially due to the replacement of large conventional power plants with dispersed and distributed renewable power generators connected to both transmission and distribution grids, which is causing several concerns on existing transmission and distribution networks, which are often operated very close to their maximum allowable operational limits, especially in the presence of grid congestions. To address this problem, power system operators perform preventive solutions by building new transmission and distribution assets, to increase grid meshing and inter-area power transfer capacity. Although these actions may enhance the load capability of the transmission assets and the grid flexibility, building new infrastructures is not a trivial task due to the related economic, social, and environmental matters. This panel will present the latest experience from manufacturing, specialists, academia, and Industry on the enabling synchrophasor-based technologies for increasing the flexibility, efficiency, reliability and security of transmission and distribution systems. Special attention is given to the large-scale deployment of these technologies on existing transmission and distribution assets to allow system operators to enhance the grid flexibility in the presence of severe grid congestions.

Oscillatory events have become prevalent extensively in the power grid in the recent years with greater integration of inverter-based resources (IBRs). Additionally, trips in the power grid by some of the inverters in IBRs when faults happen far away from the location of IBR have become observable in the recent years. There is potential to utilize electromagnetic transient (EMT) simulations to develop potential solutions to mitigate oscillations and/or create digital twins that can assist with enhancing the reliable operation of power grids. In this panel session, there will be a discussion on all studies that can be performed using EMT simulations that include oscillations mitigation or potential creation of digital twins.

Essays on knowledge spillovers
Creators: name: Cai, Jie
Publisher: name: University of British Columbia
Year: 2011

description: This thesis studies three issues involving knowledge diffusion across firms. The first chapter explains two data facts related to firm size distribution. First, it uses sector-specific inter-firm knowledge spillovers to explain sectoral differences in firm size heterogeneity. Greater inter-firm knowledge spillovers in a sector induce firms in that sector to invest relatively more in imitation. Greater imitation also causes faster catch-up by lagging firms and declining firm growth rate with firm size. Hence, the sectoral firm size distribution becomes more homogeneous in sectors with greater knowledge spillovers. Second, in a multi-sector version of this environment, I use inter-sector knowledge spillovers to explain the observed dependent Pareto size distributions in every subset of the economy. I test the model using patent citation data and find support for both its sectoral and aggregate predictions. The second chapter rationalizes firms’ motivation to build directed links with each other and formalizes the dynamic formation process that generates the observed network structure, including triple Power-law degree distributions, in the patent citation networks. Networks allow firms to become more specialized without losing customers, because having more firms in the market results not only in competitors but also in potential partner who redirect customers. Using firm citation panel data from the NBER Patent Citation Database, I estimate the model’s parameters and simulate networks that exhibit similar structure features as corresponding real networks. The third chapter documents a new empirical fact that larger firms update information faster than smaller firms in patent citation data and address its macroeconomic implications. In a model with size-dependent reaction time lag and Pareto firm size distribution, the gradual spread of a firm-level technology shock generates a persistent and hump-shaped aggregate output growth rate. Greater information heterogeneity across firms de-synchronizes the co-movement among firms of different sizes, and hence causes a less volatile, smoother and longer aggregate business cycle. The model is well suited to explaining several timing relations of the business cycle. For example, productivity dispersion is pro-cyclical, the top firm’s growth rate predicts future GDP growth, and investment leads hiring over the business cycle.

description: We explicitly truncate N = 8 gauged supergravity in five dimensions to its SU(3)-invariant sector with dilaton and axion fields. We show that this truncation has a solution which is identical to the super Janus constructed in N = 2 gauged supergravity in five dimensions. Then we lift the solution of the SU(3)-invariant truncation to type IIB supergravity by employing the consistent truncation ansatz. We show that the lifted solution falls into a special case of the supersymmetric Janus solutions constructed in type IIB supergravity. Additionally, we also prove that the lifted solution provides a particular example of the consistent truncations of type IIB supergravity on Sasaki-Einstein manifolds.

description: The k=3 Read-Rezayi (RR) parafermion quantum Hall state hosts non-Abelian excitations which provide a platform for the universal topological quantum computation. Although the RR state may be realized at the filling factor ν=12/5 in GaAs-based two-dimensional electron systems, the corresponding quantum Hall state is weak and at present nearly impossible to study experimentally. Here we argue that the RR state can alternatively be realized in a class of chiral materials with massless and massive Dirac-like band structure. This family of materials encompasses monolayer and bilayer graphene, as well as topological insulators. We show that, compared to GaAs, these systems provide several important advantages in realizing and studying the RR state. Most importantly, the effective interactions can be tuned {\it in situ} by varying the external magnetic field, and by designing the dielectric environment of the sample. This tunability enables the realization of RR state with controllable energy gaps in different Landau levels. It also allows one to probe the quantum phase transitions to other compressible and incompressible phases.

Analyzing Guarded Protocols: Better Cutoffs, More Systems, More Expressivity
Creators: name: Jacobs, Swen

Publisher: name: CISPA
Year: 2023

description: We study cutoff results for parameterized verification and synthesis of guarded protocols, as introduced by Emerson and Kahlon (2000). Guarded protocols describe systems of processes whose transitions are enabled or disabled depending on the existence of other processes in certain local states. Cutoff results reduce reasoning about systems with an arbitrary number of processes to systems of a determined, fixed size. Our work is based on the observation that existing cutoff results for guarded protocols are often impractical, since they scale linearly in the number of local states of processes in the system. We provide new cutoffs that scale not with the number of local states, but with the number of guards in the system, which is in many cases much smaller. Furthermore, we consider generalizations of the type of guards and of the specifications under consideration, and present results for problems that have not been known to admit cutoffs before.
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave pairing interaction

description: We investigate single-particle properties of a one-component Fermi gas with a tunable p-wave interaction. Including pairing fluctuations associated with this anisotropic interaction within a $T$-matrix theory, we calculate the single-particle density of states, as well as the spectral weight, above the superfluid transition temperature $T_{\rm c}$. Starting from the weak-coupling regime, we show that the so-called pseudogap first develops in these quantities with increasing the interaction strength. However, when the interaction becomes strong to some extent, the pseudogap becomes obscure to eventually disappear in the strong-coupling regime. This non-monotonic interaction dependence is quite different from the case of an s-wave interaction, where the pseudogap simply develops with increasing the interaction strength. The difference between the two cases is shown to originate from the momentum dependence of the p-wave interaction, which vanishes in the low momentum limit. We also identify the pseudogap regime in the phase diagram with respect to the temperature and the p-wave interaction strength. Since the pseudogap is a precursor phenomenon of the superfluid phase transition, our results would be useful for the research toward the realization of p-wave superfluid Fermi gases.

description: Inclusive cross sections $σ^A=Ed^3{σ(X,P_t^2)/d^3p}$ of antiproton and negative pion production on Be, Al, Cu and Ta targets hit by 10 GeV protons were measured at the laboratory angles of 10.5$^{\circ}$ and 59$^{\circ}$. Antiproton cross sections were obtained in both kinematically allowed and kinematically forbidden regions for antiproton production on a free nucleon. The antiproton cross section ratio as a function of the longitudinal variable $X$ exhibits three separate plateaus which gives evidence for the existence of compact baryon configurations in nuclei-small-distance scaled objects of nuclear structure. Comparability of the measured cross section ratios with those obtained in the inclusive electron scattering off nuclei suggests a weak antiproton absorption in nuclei. Observed behavior of the cross section ratios is interpreted in the framework of a model considering the hadron production as a fragmentation of quarks (antiquarks) into hadrons. It has been established that the antiproton formation length in nuclear matter can reach the magnitude of 4.5 fm.
