description: Deep neural networks (DNNs) have progressed rapidly during the past decade and have been deployed in various real-world applications. Meanwhile, DNN models have been shown to be vulnerable to security and privacy attacks. One such attack that has attracted a great deal of attention recently is the backdoor attack. Specifically, the adversary poisons the target model's training set to mislead any input with an added secret trigger to a target class. Previous backdoor attacks predominantly focus on computer vision (CV) applications, such as image classification. In this paper, we perform a systematic investigation of backdoor attack on NLP models, and propose BadNL, a general NLP backdoor attack framework including novel attack methods. Specifically, we propose three methods to construct triggers, namely BadChar, BadWord, and BadSentence, including basic and semantic-preserving variants. Our attacks achieve an almost perfect attack success rate with a negligible effect on the original model's utility. For instance, using the BadChar, our backdoor attack achieves a 98.9% attack success rate with yielding a utility improvement of 1.5% on the SST-5 dataset when only poisoning 3% of the original set. Moreover, we conduct a user study to prove that our triggers can well preserve the semantics from humans perspective.

Vision assisted system for industrial robot training
Creators: name: Sang, Tao
Publisher: name: University of British Columbia
Year: 2009

description: In an industrial environment, robotic manipulators are trained to perform repetitive operations at high speed. For safety reasons, the power to the robotic manipulator must be shut off whenever the operator enters the robotic work-cell. However, during training, human operators are required to enter the work-cell frequently to verify the manipulator positions. This cycle of "power-off-check-power-on-train" is time consuming and expensive. This work presents a self-calibrated vision system for human-guided robot training. The objective of the system is to simplify the training process thus reducing the training time and cost. The system assists robot operators in training industrial robots quickly, safely, and accurately. The system can be used in various industrial environments and requires no predetermined model of the working space. First, the system self-calibrates to compute the initial camera locations and orientations. Next, the user demonstrates the tool path that is to be followed by the robot arm using a 6-degree of freedom training medium. Finally, the system optimizes the camera locations so that, at those locations, the cameras can provide sufficient images for the operator to observe and perform further remote training of the robot as required without entering the workcell. The result shows that with the help of the vision system, the number of times that a human is required to enter the robotic work-cell is reduced to no more than 3 times for robot task training. At the same time, the accuracy of the training process is not compromised with the use of the vision system.

description: The Deepfake phenomenon has become very popular nowadays thanks to the possibility to create incredibly realistic images using deep learning tools, based mainly on ad-hoc Generative Adversarial Networks (GAN). In this work we focus on the analysis of Deepfakes of human faces with the objective of creating a new detection method able to detect a forensics trace hidden in images: a sort of fingerprint left in the image generation process. The proposed technique, by means of an Expectation Maximization (EM) algorithm, extracts a set of local features specifically addressed to model the underlying convolutional generative process. Ad-hoc validation has been employed through experimental tests with naive classifiers on five different architectures (GDWCT, STARGAN, ATTGAN, STYLEGAN, STYLEGAN2) against the CELEBA dataset as ground-truth for non-fakes. Results demonstrated the effectiveness of the technique in distinguishing the different architectures and the corresponding generation process.

description: Two-dimensional (2D) bismuth oxyselenide (Bi2O2Se) with high electron mobility is advantageous in future high-performance and flexible electronic and optoelectronic devices. However, transfer of thin Bi2O2Se flakes is rather challenging, restricting measurements of its mechanical properties and application exploration in flexible devices. Here, we develop a reliable and effective polydimethylsiloxane (PDMS)-mediated method that allows transferring thin Bi2O2Se flakes from grown substrates onto target substrates like micro-electro-mechanical system substrates. The high fidelity of the transferred thin flakes stems from the high adhesive energy and flexibility of PDMS film. For the first time, the mechanical properties of 2D Bi2O2Se are experimentally acquired with nanoindentation method. We found that few-layer Bi2O2Se exhibits a large intrinsic stiffness of 18-23 GPa among 2D semiconductors, and a Young' s modulus of 88.7 +- 14.4 GPa which is consistent with the theoretical values. Furthermore, few-layer Bi2O2Se can withstand a high radial strain of more than 3%, demonstrating excellent flexibility. The development of the reliable transfer method and documentation of mechanical properties of 2D Bi2O2Se jointly fill the gap between theoretical prediction and experimental verification of mechanical properties of this emerging material, and will promote flexible electronics and optoelectronics based on 2D Bi2O2Se.

description: Cauchy-characteristic evolution (CCE) is a powerful method for accurately extracting gravitational waves at future null infinity. In this work, we extend the previously implemented CCE system within the numerical relativity code SpECTRE by incorporating a scalar field. This allows the system to capture features of beyond-general-relativity theories. We derive scalar contributions to the equations of motion, Weyl scalar computations, Bianchi identities, and balance laws at future null infinity. Our algorithm, tested across various scenarios, accurately reveals memory effects induced by both scalar and tensor fields and captures Price's power-law tail ($u^{-l-2}$) in scalar fields at future null infinity, in contrast to the $t^{-2l-3}$ tail at future timelike infinity.

title: Dynamic Modeling of a Nuclear Integrated Energy System With Thermal Energy Storage and Hydrogen Production
Creators: name: Dana, Seth J.
Publisher: name: Utah State University
Year: 2024

description: Historically, nuclear reactors have used water for cooling and moderating the nuclear reaction within the core. Advanced generation IV nuclear reactors currently under development are designed with different coolants which enable operation at higher temperatures. A higher operating temperature makes nuclear power suitable for co-located hydrogen production via high temperature electrolysis. Natrium, an advanced reactor design by TerraPower and GE Hitachi, combines a sodium fast reactor with molten salt thermal energy storage. The work presented in this thesis models and analyzes three Natrium systems which integrate hydrogen production with the Natrium nuclear power plant. The first two configurations focus on improving thermal efficiency of the electricity generation while the third and final configuration improves hydrogen production efficiency. A techno-economic analysis of the Natrium system with co-located hydrogen production in three US locations (California, Texas, and Midwest states) determines the economic benefits of hydrogen production and storage coupled with the Natrium design. Results indicate that coupling the Natrium system with hydrogen production can boost thermal efficiency of the Natrium steam cycle by 1%, and using steam from the steam cycle as feedstock for hydrogen production increases overall system efficiency by 3%. The economic analysis demonstrates that integrating the Natrium system with hydrogen production enhances the economic viability, particularly in regions with less volatile and lower electricity prices. Incorporating hydrogen storage into the system enhances plant flexibly, which is advantageous in volatile electricity markets. In addition, hydrogen production and storage offer economic stability in markets with volatile electricity prices due to its constant price and production rate.

description: Assume two finite families $\mathcal A$ and $\mathcal B$ of convex sets in $\mathbb{R}^3$ have the property that $A\cap B\ne \emptyset$ for every $A \in \mathcal A$ and $B\in \mathcal B$. Is there a constant $γ>0$ (independent of $\mathcal A$ and $\mathcal B$) such that there is a line intersecting $γ|\mathcal A|$ sets in $\mathcal A$ or $γ|\mathcal B|$ sets in $\mathcal B$? This is an intriguing Helly-type question from a paper by Martínez, Roldan and Rubin. We confirm this in the special case when all sets in $\mathcal A$ lie in parallel planes and all sets in $\mathcal B$ lie in parallel planes; in fact, all sets from one of the two families has a line transversal.

On Pseudo-Hermitian Hamiltonians and Their Hermitian Counterparts

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In the context of two particularly interesting non-Hermitian models in quantum mechanics we explore the relationship between the original Hamiltonian H and its Hermitian counterpart h, obtained from H by a similarity transformation, as pointed out by Mostafazadeh. In the first model, due to Swanson, h turns out to be just a scaled harmonic oscillator, which explains the form of its spectrum. However, the transformation is not unique, which also means that the observables of the original theory are not uniquely determined by H alone. The second model we consider is the original PT-invariant Hamiltonian, with potential V=igx^3. In this case the corresponding h, which we are only able to construct in perturbation theory, corresponds to a complicated velocity-dependent potential. We again explore the relationship between the canonical variables x and p and the observables X and P.

description: We present the full panchromatic afterglow light curve data of GW170817, including new radio data as well as archival optical and X-ray data, between 0.5 and 940 days post-merger. By compiling all archival data, and reprocessing a subset of it, we have evaluated the impact of differences in data processing or flux determination methods used by different groups, and attempted to mitigate these differences to provide a more uniform dataset. Simple power-law fits to the uniform afterglow light curve indicate a $t^{0.86\pm0.04}$ rise, a $t^{-1.92\pm0.12}$ decline, and a peak occurring at $155\pm4$ days. The afterglow is optically thin throughout its evolution, consistent with a single spectral index ($-0.584\pm0.002$) across all epochs. This gives a precise and updated estimate of the electron power-law index, $p=2.168\pm0.004$. By studying the diffuse X-ray emission from the host galaxy, we place a conservative upper limit on the hot ionized ISM density, $

Observa-se que o volume de trabalhos, discussões e estudos no decorrer do tempo, além de ilustrar a importância do assunto, permitiu o constante melhoramento dos métodos de cálculo e a defesa de diferentes pontos de vistas, levando inclusive à divisão de seu corpo teórico em algumas principais linhas ou correntes de pesquisa. A história da pesquisa tem seus primeiros registros no início do século XVIII, desenvolve-se sob vários enfoques e se enriquece ainda mais a partir do século XX. Esses enfoques gradualmente ajudaram a formar as três mais importantes abordagens da teoria de índices de preço, tais como são representados na literatura atual: a “abordagem estatística”, a “abordagem axiomática” e a “abordagem econômica”. Apesar da divisão, observa-se certa complementaridade já que a elaboração prática de índices de preços utiliza conceitos relacionados às três abordagens de forma integrada, dependendo de cada etapa de sua elaboração. ---------------------------------------------The present work aims at to revise the historical antecedents of the research of a tool very used and published in economical studies in world and of great attractiveness and application in the agribusiness studies: the price indexes. It was observed that the volume of works, discussions and studies of the price indexes theory in elapsing of the time, besides illustrating the importance of the subject, it allowed the constant improvement of the calculation methods and the defense of different points of views, taking besides to the division of your theoretical body in some main lines or research currents. The history of the research has their first registrations in the beginning of the century XVIII, it grows under several focuses and still gets rich more starting from the century XX. Those focuses gradually helped to form the three more important approaches of the price index theory, such as they are represented in the current literature: the "statistical approach", the "axiomatic approach" and the "economical approach". In spite of the division, certain complementarity is observed since the practical elaboration of price indexes uses concepts related to the three approaches in an integrated way, depending on each stage of your elaboration.

description: In this work, we investigate the problem of lip-syncing a talking face video of an arbitrary identity to match a target speech segment. Current works excel at producing accurate lip movements on a static image or videos of specific people seen during the training phase. However, they fail to accurately morph the lip movements of arbitrary identities in dynamic, unconstrained talking face videos, resulting in significant parts of the video being out-of-sync with the new audio. We identify key reasons pertaining to this and hence resolve them by learning from a powerful lip-sync discriminator. Next, we propose new, rigorous evaluation benchmarks and metrics to accurately measure lip synchronization in unconstrained videos. Extensive quantitative evaluations on our challenging benchmarks show that the lip-sync accuracy of the videos generated by our Wav2Lip model is almost as good as real synced videos. We provide a demo video clearly showing the substantial impact of our Wav2Lip model and evaluation benchmarks on our website: \url{cvit.iiit.ac.in/research/projects/cvit-projects/a-lip-sync-expert-is-all-you-need-for-speech-to-lip-generation-in-the-wild}.

3D Microstructure-Based Finite Element Simulation of ColdSprayed Al-Al2O3 Composite Coatings Under Quasi-Static Compression and Indentation Loading

This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al2O3) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight fraction, particle size, and porosity) of the MMC coatings, 3D representative volume elements (RVEs) were generated by using Digimat software and then imported into ABAQUS/Explicit. State-of-the-art physics-based modeling approaches were incorporated into the model to account for particle cracking, interface debonding, and ductile failure of the matrix. This allowed for analysis and informing on the deformation and failure responses. The model was validated with experimental results for cold-sprayed Al-34 wt.% Al2O3 and Al-46 wt.% Al2O3 metal matrix composite coatings under quasi-static compression by comparing the stress versus strain histories and observed failure mechanisms (e.g., matrix ductile failure). The results showed that the computational framework is able to capture the response of this cold-sprayed material system under compression and indentation, both qualitatively and quantitatively. The outcomes of this work have implications for extending the model to materials design and for applications involving different types of loading in real-world application (e.g., erosion and fatigue).

description: We report on the results of a NuSTAR observation of the Supergiant Fast X-ray Transient pulsar IGRJ11215-5952 during the peak of its outburst in June 2017. IGRJ11215-5952 is the only SFXT undergoing strictly periodic outbursts, every 165 days. NuSTAR caught several X-ray flares, spanning a dynamic range of 100, and detected X-ray pulsations at 187.0 s, consistent with previous measurements. The spectrum from the whole observation is well described by an absorbed power-law (with a photon index of 1.4) modified, above 7 keV, by a cutoff with an e-folding energy of 24 keV. A weak emission line is present at 6.4 keV, consistent with Kalpha emission from cold iron in the supergiant wind. The time-averaged flux is 1.5E-10 erg/cm2/s (3-78 keV, corrected for the absorption), translating into an average luminosity of about 9E35 erg/s (1-100 keV, assuming a distance of 6.5 kpc). The NuSTAR observation allowed us to perform the most sensitive search for cyclotron resonant scattering features in the hard X-ray spectrum, resulting in no significant detection in any of the different spectral extractions adopted (time-averaged, temporally-selected, spin-phase-resolved and intensity-selected spectra). The pulse profile showed an evolution with both the energy (3-12 keV energy range compared with 12-78 keV band) and the X-ray flux: a double peaked profile was evident at higher fluxes (and in both energy bands), while a single peaked, sinusoidal profile was present at the lowest intensity state achieved within the NuSTAR observations (in both energy bands). The intensity-selected analysis allowed us to observe an anti-correlation of the pulsed fraction with the X-ray luminosity. The pulse profile evolution can be explained by X-ray photon scattering in the accreting matter above magnetic poles of a neutron star at the quasi-spherical settling accretion stage.

This study traces these discrepancies back to their origins. We start by generating a digital twin of one standard experimental set-up. This twin is subsequently simplified in steps to understand the effect of non-ideal thermal boundary conditions, and the experimental measurement procedure is mimicked using numerical data. Although this allows explaining the increased observed size of the flow structures in the experiment relative to past numerical simulations, our data suggests that the vertical velocity magnitude has been underestimated in the experiments. A subsequent re-assessment of the latter's original data reveals an incorrect calibration model. The re-processed data show a relative increase in $u_{z}$ of roughly $24 \%$, resolving the previously observed discrepancies. This digital twin of a laboratory experiment for thermal convection at Rayleigh numbers $\Ra = \left\{ 2, 4, 7 \right\} \times 10^{5}$, a Prandtl number $\Pr = 7.1$, and an aspect ratio $Γ= 25$ highlights the role of different thermal boundary conditions as well as a reliable calibration and measurement procedure.

description: We present an analysis of infrared/optical/ultraviolet spectra of the two images of the first gravitationally lensed quasar Q0957+561A, B. The Hubble Space Telescope observations of Q0957+561A and Q0957+561B are separated in time by the known time delay in this system, so we can directly deduce the flux ratios. These flux ratios of images lead to important information on the dark halo of the main lens galaxy (a giant elliptical at redshift z = 0.36). Our measurements for the continuum are in good agreement with extinction in the elliptical galaxy and a small fraction of mass in collapsed objects (no need for gravitational microlensing). From the continuum and emission line ratios, we also show evidence in favour of the existence of a network of compact dusty clouds.

description: O processo de globalização e a abertura comercial brasileira são fenômenos que contribuem para explicar a maior complexidade característica ao ambiente no qual o produtor rural está inserido, exigindo deste agente maior dinamismo e capacidade adaptativa no que tange à estruturação de suas estratégias e ao seu processo de tomada de decisão. Fica evidenciada, neste contexto, a necessidade de uma visão sistêmica na gestão dos recursos e potencialidades da propriedade rural, a fim de atingir os objetivos propostos. Sendo assim, buscou-se neste artigo resgatar aspectos teóricos que contribuam para o entendimento do processo de tomada de decisão do produtor rural em um enfoque sistêmico, salientando a necessidade de desenvolvimento de capacidades e aprendizagem por este agente, o que pode ser desenvolvido através da implementação de alianças estratégicas com outros produtores.---------------------------------------------The globalization process and the brazilian opening trade are phenomenons that contribute to explain the largest complexity caracteristic of the environment that the farmer is inserted, demanding from this agent more dynamism and adaptative capacity to structure their strategies and decision making process. Is evidenced, in this context, the necessity of a sistemic view in the management of the farm’s resources and potentialities, to reach the goals proposed. Then, this paper search theoric aspects that contribute to the understanding of the farmer decision making process in a sistemic approach, evidencing the necessity to develop the farmer’s capacitys and learning, that can be developed through the implementation of strategic aliances among other farmers.

description: The presence of obscuring material (or a dusty `torus') in active galactic nuclei (AGN) is central to the unification model for AGN. Two models, the multi-population model for radio sources and the receding torus model, are capable of describing observational properties of powerful radio galaxies and radio quasars. Here, I study the changes of the opening angle of the obscuring torus with radio luminosity at 151 MHz, [O III] emission-line luminosity and cosmic epoch aiming to discriminate between two working models. An analytical expression relating the half opening angle of the torus to the mean projected linear sizes of double radio galaxies and quasars is derived. The sizes of powerful double radio sources taken from the combined sample of 3CRR, 6CE and 7CR complete samples are used to estimate the torus opening angle. I found a statistically significant correlation between the half opening angle of the torus and [O III] emission-line luminosity. The opening angle increases from 20 to 60 degrees with increasing [O III] emission-line luminosity. This correlation is interpreted as direct evidence of the receding torus around central engines of powerful double radio sources.

description: Spatially structured light fields applied to semiconductor quantum dots yield fundamentally different absorption spectra than homogeneous beams. In this paper, we theoretically discuss the resulting spectra for different light beams using a cylindrical multipole expansion. For the description of the quantum dots we employ a model based on the effective mass approximation including Coulomb and valence band mixing. The combination of a single spatially structured light beam and state mixing allows all exciton states in the quantum dot to become optically addressable. Furthermore, we demonstrate that the beams can be tailored such that single states are selectively excited, without the need of spectral separation. Using this selectivity, we propose a method to measure the exciton wave function of the quantum dot eigenstate. The measurement goes beyond electron density measurements by revealing the spatial phase information of the exciton wave function. Thereby polarization sensitive measurements are generalized by including the infinitely large spatial degree of freedom.

description: We present a model to study secularly and tidally evolving three-body systems composed by two low-mass planets orbiting a star, in the case where the bodies rotation axes are always perpendicular to the orbital plane. The tidal theory allows us to study the spin and orbit evolution of both stiff Earth-like planets and predominantly gaseous Neptune-like planets. The model is applied to study two recently-discovered exoplanetary systems containing potentially habitable exoplanets (PHE): LHS-1140 b-c and K2-18 b-c. For the former system, we show that both LHS-1140 b and c must be in nearly-circular orbits. For K2-18 b-c, the combined analysis of orbital evolution timescales with the current eccentricity estimation of K2-18 b allows us to conclude that the inner planet (K2-18 c) must be a Neptune-like gaseous body. Only this would allow for the eccentricity of K2-18 b to be in the range of values estimated in recent works ($e=0.20 \pm 0.08$), provided that the uniform viscosity coefficient of K2-18 b is greater than $2.4 \times 10^{19} \ \textrm{Pa s}$ (which is a value characteristic of stiff bodies) and supposing that such system has an age of some Gyr.

Diagnosis of the effects of thermal cycling on PEMFCS via electrochemical impedance spectroscopy
Creators: name: Connell, Robert Michael
Publisher: name: University of British Columbia
Year: 2009

description: A new method of applying electrochemical impedance spectroscopy (EIS) as a diagnostic tool was used to investigate the effects of thermal cycling on proton exchange membrane fuel cells. The focus of this thesis was the generation of hardware required to accomplish this goal. Unlike previous work, this study used a specialized load bank to draw the periodic current necessary for impedance measurements. This study also required the design and construction of new hardware to allow accelerated cycling of a single cell between ambient and operational temperatures. The equipment was tested (through experimentation) both to verify its functionality and to serve as a roadmap for a more thorough investigation into the effects of thermal cycling. It was hypothesized that cumulative damage due to thermal cycling would correspond to changes in cell impedance that were observable in characteristic frequency ranges. The equipment was used to perform galvanostatic impedance measurements in situ. Measurements were made at four different current densities (0.2, 0.4, 0.6, and 0.8A/cm²) over the frequency range 1 to lxlO⁶ Hz. Cell temperatures were cycled between 20-80°C or 30-90°C at a rate of 1°C per second for up to 2000 cycles. The recorded data represents the first reported measurements covering these ranges. The measured spectra were repeatable, produced results consistent with previous work and were as accurate as impedance measurements made using the traditional setup. Observed changes in impedance spectra as a function of thermal cycling were relatively minor but significant changes in impedance magnitude between 10 and 1000 Hz and changes in phase angle at frequencies greater than 10 kHz were measured. The effects of thermal cycling on MEA performance were minor with no irrecoverable damage recorded at moderate stack pressures of 120 PSI and degradation rates below 0.057mV/cycle at increased stack pressure of 350 PSI. These results suggest that stack sealing pressure is a factor in thermal degradation and is an avenue for continued investigation. Experimental data suggests that the main failure mode of thermal cycling is the formation of a contact resistance between the bipolar plates and current collectors due to degradation of the graphite. The contact resistance grew as large as 2xl0⁻⁴ Ωcm², leading to a potential drop of 0.25V, but available data was insufficient to calculate a growth rate.

description: As variáveis econômicas são afetadas por políticas econômicas e por eventos de caráter exógeno, como bruscas variações climáticas, guerras e desastres ecológicos. Esses eventos caracterizam efeitos conhecidos como “outlier” e devem ser considerados na modelagem econométrica. O estudo procurou analisar a integração de mercado juntamente com os efeitos da presença da quebra estrutural nas séries do preço do boi de corte recebido pelo produtor no estado de Goiás e no Brasil. A principal contribuição do estudo em relação a outros trabalhos foi a utilização do teste de raiz unitária desenvolvido por VOGELSANG (1999) juntamente com teste de co-integração para a presença de "outlier" desenvolvido por GREGORY e HANSEN (1996). Dentre os principais resultados, destaca-se que os preços no Estado de Goiás tendem a acompanhar os preços de outras “praças” de comercialização, mesmo na presença do “outlier”. ---------------------------------------------The economics variables are affected by economics policies and events of nature, climatic variations, and environment disasters. These events characterize known effect as structural breaks and must be considered in the Econometric Analysis. This paper analyze the integration of bull market prices to Goiás and Brazil under effect of structural break. Furthermore, the empirical analysis used models of unit test root VOGELSANG (1999) and co-integration with rigime shift developed for GREGORY and HANSEN (1996).
