description: Recent works have demonstrated the feasibility of GAN-based morphing attacks that reach similar success rates as more traditional landmark-based methods. This new type of "deep" morphs might require the development of new adequate detectors to protect face recognition systems. We explore simple deep morph detection baselines based on spectral features and LBP histograms features, as well as on CNN models, both in the intra-dataset and cross-dataset case. We observe that simple LBP-based systems are already quite accurate in the intra-dataset setting, but struggle with generalization, a phenomenon that is partially mitigated by fusing together several of those systems at score-level. We conclude that a pretrained ResNet effective for GAN image detection is the most effective overall, reaching close to perfect accuracy. We note however that LBP-based systems maintain a level of interest : additionally to their lower computational requirements and increased interpretability with respect to CNNs, LBP+ResNet fusions sometimes also showcase increased performance versus ResNet-only, hinting that LBP-based systems can focus on meaningful signal that is not necessarily picked up by the CNN detector.

Publisher: name: Zenodo

description: Destination competitiveness has become a critical issue in today’s increasingly challenging tourism market. Many studies have indicated that tourists and their needs stand as the ultimate driving force which influences competition and competitiveness in the tourism destination. Today, destinations eventually compete on the quality of tourism experience offered to visitors. However, limited research has been undertaken to examine destination competitiveness from the tourist’s perspective. The purpose of this study is to investigate the effect of quality of tourism experience on tourist’s perception of destination competitiveness. A destination competitiveness model based on the perceptions of tourists and a measurement instrument to assess the constructs of the model were developed for this study. The model proposes that tourists perceived destination competitiveness is affected by the quality of tourism experience; which includes the experience in pre-trip planning, en-route, on-site, and after-trip (reflection) phases.

description: A common problem that affects simulations of complex systems within the computational physics and chemistry communities is the so-called sampling problem or rare event problem where proper sampling of energy landscapes is impeded by the presences of high kinetic barriers that hinder transitions between metastable states on typical simulation time scales. Many enhanced sampling methods have been developed to address this sampling problem and more efficiently sample rare event systems. An interesting idea, coming from the field of statistics, was introduced in a recent work (Y. Lu, J. Lu, and J. Nolen, arXiv:1905.09863, 2019) in the form of a novel sampling algorithm that augments overdamped Langevin dynamics with a birth-death process. In this work, we expand on this idea and show that this birth-death sampling scheme can efficiently sample prototypical rare event energy landscapes, and that the speed of equilibration is independent of the barrier height. We amend a crucial shortcoming of the original algorithm that leads to incorrect sampling of barrier regions by introducing a new approximation of the birth-death term. We establish important theoretical properties of the modified algorithm and prove mathematically that the relevant convergence results still hold. We investigate via numerical simulations the effect of various parameters, and we investigate ways to reduce the computational effort of the sampling scheme. We show that the birth-death mechanism can be used to accelerate sampling in the more general case of underdamped Langevin dynamics that is more commonly used in simulating physical systems. Our results show that this birth-death scheme is a promising method for sampling rare event energy landscapes.

description: Hybrid aerial-terrestrial communication networks based on Low Altitude Platforms (LAPs) are expected to optimally meet the urgent communication needs of emergency relief and recovery operations for tackling large scale natural disasters. The energy-efficient operation of such networks is important given the fact that the entire network infrastructure, including the battery operated ground terminals, exhibits requirements to operate under power-constrained situations. In this paper, we discuss the design and evaluation of an adaptive cooperative scheme intended to extend the survivability of the battery operated aerial-terrestrial communication links. We propose and evaluate a real-time adaptive cooperative transmission strategy for dynamic selection between direct and cooperative links based on the channel conditions for improved energy efficiency. We show that the cooperation between mobile terrestrial terminals on the ground could improve the energy efficiency in the uplink depending on the temporal behavior of the terrestrial and the aerial uplink channels. The corresponding delay in having cooperative (relay-based) communications with relay selection is also addressed. The simulation analysis corroborates that the adaptive transmission technique improves the overall energy efficiency of the network whilst maintaining low latency enabling real time applications.

description: This paper defines the notion of analogical dissimilarity between four objects, with a special focus on objects structured as sequences. Firstly, it studies the case where the four objects have a null analogical dissimilarity, i.e. are in analogical proportion. Secondly, when one of these objects is unknown, it gives algorithms to compute it. Thirdly, it tackles the problem of defining analogical dissimilarity, which is a measure of how far four objects are from being in analogical proportion. In particular, when objects are sequences, it gives a definition and an algorithm based on an optimal alignment of the four sequences. It gives also learning algorithms, i.e. methods to find the triple of objects in a learning sample which has the least analogical dissimilarity with a given object. Two practical experiments are described: the first is a classification problem on benchmarks of binary and nominal data, the second shows how the generation of sequences by solving analogical equations enables a handwritten character recognition system to rapidly be adapted to a new writer.

Equivariant de Rham Theorem

description: The aim of this thesis is to study the equivariant cohomology of a topological group acting continuously on a topological space, the equivariant de Rham cohomology of a Lie group acting smoothly on a smooth manifold and the relation between the above constructions. Specifically, first we cover the basic theory of principal bundles and we introduce the Borel Model. Then, we introduce the notion of g-differential graded algebras and we construct the Weil and the Cartan Model. Finally, we prove Cartan’s theorem and we apply it together with some approximation theorems to prove the equivariant de Rham theorem. The latter theorem is the main result of this thesis and it simply states that in the special case of a compact connected Lie group acting smoothly on a smooth manifold, the equivariant cohomology with real coefficients is naturally isomorphic to the equivariant de Rham cohomology.

description: Advances in photonics require photon-number resolved simulations of quantum optical experiments with Gaussian states. We demonstrate a simple and versatile method to simulate the photon statistics of general multimode Gaussian states. The derived generating functions enable simulations of the photon number distribution, cumulative probabilities, moments, and factorial moments of the photon statistics of Gaussian states as well as of multimode photon-added and photon-subtracted Gaussian states. Numerical results are obtained by automatic differentiation of these generating functions by employing the software framework PyTorch. Our approach is particularly well suited for practical simulations of the photon statistics of quantum optical experiments in realistic scenarios with low photon numbers, in which various sources of imperfections have to be taken into account. As an example, we calculate the detection probabilities for a recent multipartite time-bin coding quantum key distribution setup and compare them with the corresponding experimental values.

description: A novel state is predicted for a S/F heterostructure. It is shown that the equilibrium F/S bilayer can be in a bistable state: one state is ground and the other is metastable. One of these states is always normal and the other is superconducting. One can switch between these states by an external control parameter, for example, by an applied magnetic field. This phenomenon can manifest itself through the hysteresis behavior upon varying the applied magnetic field or, even, temperature. It can also lead to transition of the heterostructure into the superconducting state upon increase of the temperature.

description: Classical force fields (FF) based on machine learning (ML) methods show great potential for large scale simulations of materials. MLFFs have hitherto largely been designed and fitted for specific systems and are not usually transferable to chemistries beyond the specific training set. We develop a unified atomisitic line graph neural network-based FF (ALIGNN-FF) that can model both structurally and chemically diverse materials with any combination of 89 elements from the periodic table. To train the ALIGNN-FF model, we use the JARVIS-DFT dataset which contains around 75000 materials and 4 million energy-force entries, out of which 307113 are used in the training. We demonstrate the applicability of this method for fast optimization of atomic structures in the crystallography open database and by predicting accurate crystal structures using genetic algorithm for alloys.

description: Baro river basin located in southwest of Ethiopia is a largest sub basin of Baro-Acoobo basin. For the proper utilization and management of groundwater resource in the basin, it required to know its spatial distribution. Hence, geographic information system and remote sensing techniques were used to analyze the groundwater system based on seven selected groundwater influence factors thematic maps. The thematic maps we used were geology, soil, lineament density, drainage density, rainfall distribution, slope and land use maps. Lineament and land use maps were prepared through the process of remote sensing techniques from Landsat 4-5 imagery using ERDAS imagine and PCI Geomatica softwares. Other thematic maps were prepared using Arc GIS 9.3 from DEM and previous prepared soil and geology maps .for each maps weight value was estimated by using PriEst software after assigning weight value of domain effect by using pairwise comparison based on Saaty’s analytical hierarchy process. Finally thematic layers were integrated in Arc GIS 9.3 based on estimated weight values. In the basin, four groundwater potential zones were identified; namely: excellent, good, moderate and poor. Excellent groundwater potential zones are associated with areas of alluvial deposition, flat and sand dominant soil group of western part of the basin; north and eastern portion of basin have good and moderate potential zone. Poor potential zone are in areas of mountain areas which have steep slope and high drainage density in center of the basin.

description: Open-source journalism emerged as a new phenomenon in the media ecosystem, which uses crowdsourcing to fact-check and generate investigative reports for world events using open sources (e.g., social media). A particularly prominent example is Bellingcat. Bellingcat is known for its investigations on the illegal use of chemical weapons during the Syrian war, the Russian responsibility for downing flight MH17, the identification of the perpetrators in the attempted murder of Alexei Navalny, and war crimes in the Russo-Ukraine war. Crucial for this is social media in order to disseminate findings and crowdsource fact-checks. In this work, we characterize the social media activities at Bellingcat on Twitter. For this, we built a comprehensive dataset of all N=24,682 tweets posted by Bellingcat on Twitter since its inception in July 2014. Our analysis is three-fold: (1) We analyze how Bellingcat uses Twitter to disseminate information and collect information from its follower base. Here, we find a steady increase in both posts and replies over time, particularly during the Russo-Ukrainian war, which is in line with the growing importance of Bellingcat for the traditional media ecosystem. (2) We identify characteristics of posts that are successful in eliciting user engagement. User engagement is particularly large for posts embedding additional media items and with a more negative sentiment. (3) We examine how the follower base has responded to the Russian invasion of Ukraine. Here, we find that the sentiment has become more polarized and negative. We attribute this to a ~13-fold increase in bots interacting with the Bellingcat account. Overall, our findings provide recommendations for how open-source journalism such as Bellingcat can successfully operate on social media.

description: We propose and theoretically analyze an experiment where displacement sensing of an optically levitated nanoparticle in front of a surface can be used to measure the induced dipole-dipole interaction between the nanoparticle and its thermal image. This is achieved by using a surface that is transparent to the trapping light but reflective to infrared radiation, with a reflectivity that can be time modulated. This dipole-dipole interaction relies on the thermal radiation emitted by a silica nanoparticle having sufficient temporal coherence to correlate the reflected radiation with the thermal fluctuations of the dipole. The resulting force is orders of magnitude stronger than the thermal gradient force and it strongly depends on the internal temperature of the nanoparticle for a particle-to-surface distance greater than two micrometers. We argue that it is experimentally feasible to use displacement sensing of a levitated nanoparticle in front of a surface as an internal thermometer. Experimental access to the internal physics of a levitated nanoparticle in vacuum is crucial to understand the limitations that decoherence poses to current efforts devoted to prepare a nanoparticle in a macroscopic quantum superposition state.

description: Background: Norfolk has the second highest teen pregnancy rate and third highest infant mortality rate in Southeastern Virginia. SIDS is the third leading cause of infant death in Virginia. Providing a group education intervention modeled after centering pregnancy gives teen mothers the opportunity to learn and receive support in a safe space in hopes of making a positive impact on their attitudes and knowledge regarding SIDS.

Hypothesis: Do the attitudes and knowledge of pregnant teens and recent teen mothers change positively after a group education intervention on sudden infant death syndrome (SIDS).

Method: Quasi-experimental non-randomized group trial. This includes pregnant females ages fifteen to nineteen in Norfolk, Virginia at a city general hospital. The data will be collected from a pretest before and posttest after a group education intervention on SIDS.

Data Collection: Hypothesis testing will be conducted using a t-test to determine group differences in attitudes and knowledge after the intervention. Participants will also be completing a PRAMS demographics survey.

Goal: To see if the SIDS education intervention has an impact on the knowledge of teen mothers in efforts to reduce the current SIDS rate contributing to Norfolk's high infant mortality rate.

description: We consider the problem of optimal planning in stochastic domains with resource constraints, where the resources are continuous and the choice of action at each step depends on resource availability. We introduce the HAO* algorithm, a generalization of the AO* algorithm that performs search in a hybrid state space that is modeled using both discrete and continuous state variables, where the continuous variables represent monotonic resources. Like other heuristic search algorithms, HAO* leverages knowledge of the start state and an admissible heuristic to focus computational effort on those parts of the state space that could be reached from the start state by following an optimal policy. We show that this approach is especially effective when resource constraints limit how much of the state space is reachable. Experimental results demonstrate its effectiveness in the domain that motivates our research: automated planning for planetary exploration rovers.
Modified Route Request Broadcasting for Improving Multipath Routing Scheme Performance in MANET
Creators: name: IJCNC
Publisher: name: Zenodo
Year: 2024

description: Mobile Ad Hoc Network (MANET) is growing in popularity with the advent of 5G wireless network and Internet of Things. In this type of peer to peer network, nodes are self-configurable and communicate among themselves wirelessly. Typically, these nodes are powered by batteries and move continuously within the specified region. In order to provide efficient communication between these devices, several routing protocols have been designed. However, most of the schemes focus on construction ofshortestroute. With this approach, it is not always possible to provide reliable and efficient path in highly dynamic environment to carry out data transmission process. In this paper, a novel Adaptive and Stable Multipath Routing Scheme (ASTMRS) has been proposed in which only peer nodes with good fitness values are allowed to process route request packet. This fitness value is estimated based on node mobility, residual energy and distance metrics. Further, each node updates its next hop information on the basis of node degree and received signal power. Simulation has been conducted under various network scenarios such as packet rate and pause time. Under different scenarios, an average improvement of 15.82% and 14.38% has been seen in packet delivery ratio(PDR) and throughput respectively; other performance metrics such as normalized routing load (NRL) and delay have been reduced to 15.58% and 13.95% respectively against AOMDV. Similarly, as compared to AODV, the scheme shows 15.96% and 15.78% improvement in terms of PDR and throughput respectively.

description: Fourteen known phenolics (1-14) and ten known flavonoids (15-24) were identified in the hydroalcoholic extract of Clitoria ternatea seeds. Phenolics such as gentisic acid (3), protocatechuic acid (5), o-coumaric acid (12) and p-coumaric acid (13) and among flavonoids, myricetin (16) were detected as the major compounds. The compounds were determined simultaneously in a multiple reaction monitoring (MRM) mode using the Acquity UPLC-H class coupled with TQD-MS/MS with an ESI source. The total phenolic and flavonoid contents were also determined. The hydroalcoholic extract evaluated for its cytotoxic effect against breast (MDA-MB-231) and pancreatic (PANC-1) cancer cells showed significant (p < 0.05) cytotoxicity with IC50 values of 45.4 and 96.5 µg/mL respectively. In addition, the cancer cells treated with the crude extract also showed elevated reactive oxygen species (ROS), upregulated caspase −8/-9/-3 activities and apoptosis of cells treated with C. ternatea extracts compared to control suggesting the pharmacological importance of this herb.

Latent Tree Models and Approximate Inference in Bayesian Networks

description: We propose a novel method for approximate inference in Bayesian networks (BNs). The idea is to sample data from a BN, learn a latent tree model (LTM) from the data offline, and when online, make inference with the LTM instead of the original BN. Because LTMs are tree-structured, inference takes linear time. In the meantime, they can represent complex relationship among leaf nodes and hence the approximation accuracy is often good. Empirical evidence shows that our method can achieve good approximation accuracy at low online computational cost.
Perturbative Unitarity of Strongly Interacting Massive Particle Models

description: Dark pion is a promising candidate for the strongly interacting massive particle dark matter. A large pion self-coupling $m_π/f_π$ tends to be required for correct relic abundance, and hence the partial-wave amplitudes can violate the perturbative unitarity even for the coupling within naïve perturbative regime. We improve the partial-wave amplitudes in order to satisfy the optical theorem. We demonstrate that the improvement is relevant only for semi-relativistic pions, and thus this does not affect the self-scattering cross section at the cosmic structures. We also discuss the impact of the improvement of the $πππ\to ππ$ scattering process, and we find that there is an upper bound on $m_π$ at which the correct relic abundance is never achieved even at large $m_π/f_π$ due to the optical theorem.

Learning Perception-Aware Agile Flight in Cluttered Environments

description: Recently, neural control policies have outperformed existing model-based planning-and-control methods for autonomously navigating quadrotors through cluttered environments in minimum time. However, they are not perception aware, a crucial requirement in vision-based navigation due to the camera's limited field of view and the underactuated nature of a quadrotor. We propose a learning-based system that achieves perception-aware, agile flight in cluttered environments. Our method combines imitation learning with reinforcement learning (RL) by leveraging a privileged learning-by-cheating framework. Using RL, we first train a perception-aware teacher policy with full-state information to fly in minimum time through cluttered environments. Then, we use imitation learning to distill its knowledge into a vision-based student policy that only perceives the environment via a camera. Our approach tightly couples perception and control, showing a significant advantage in computation speed (10 times faster) and success rate. We demonstrate the closed-loop control performance using hardware-in-the-loop simulation.
3D Galactic dust extinction mapping with multi-band photometry

description: We present a method to simultaneously infer the interstellar extinction parameters $A_0$ and $R_0$, stellar effective temperature $T_{\rm eff}$, and distance modulus $μ$ in a Bayesian framework. Using multi-band photometry from SDSS and UKIDSS, we train a forward model to emulate the colour-change due to physical properties of stars and the interstellar medium for temperatures from 4000 to 9000 K and extinctions from 0 to 5 mag. We introduce a Hertzsprung-Russel diagram prior to account for physical constraints on the distribution of stars in the temperature-absolute magnitude plane. This allows us to infer distances probabilistically. Influences of colour information, priors and model parameters are explored. Residual mean absolute errors (MAEs) on a set of objects for extinction and temperature are 0.2 mag and 300 K, respectively, for $R_0$ fixed to 3.1. For variable $R_0$, we obtain MAEs of 0.37 mag, 412.9 K and 0.74 for $A_0$, $T_{\rm eff}$ and $R_0$, respectively. Distance moduli are accurate to approximately 2 mag. Quantifying the precisions of individual parameter estimates with $68\%$ confidence interval of the posterior distribution, we obtain 0.05 mag, 66 K, 2 mag and 0.07 for $A_0$, $T_{\rm eff}$, $μ$ and $R_0$, respectively, although we find that these underestimate the accuracy of the model. We produce two-dimensional maps in extinction and $R_0$ that are compared to previous work. Furthermore we incorporate the inferred distance information to compute fully probabilistic distance profiles for individual lines of sight. The individual stellar AP estimates, combined with inferred 3D information will make possible many Galactic science and modelling applications. Adapting our method to work with other surveys, such as Pan-STARRS and Gaia, will allow us to probe other regions of the Galaxy.

description: Federated learning (FL) has been proposed as a privacy-preserving approach in distributed machine learning. A federated learning architecture consists of a central server and a number of clients that have access to private, potentially sensitive data. Clients are able to keep their data in their local machines and only share their locally trained model's parameters with a central server that manages the collaborative learning process. FL has delivered promising results in real-life scenarios, such as healthcare, energy, and finance. However, when the number of participating clients is large, the overhead of managing the clients slows down the learning. Thus, client selection has been introduced as a strategy to limit the number of communicating parties at every step of the process. Since the early naïve random selection of clients, several client selection methods have been proposed in the literature. Unfortunately, given that this is an emergent field, there is a lack of a taxonomy of client selection methods, making it hard to compare approaches. In this paper, we propose a taxonomy of client selection in Federated Learning that enables us to shed light on current progress in the field and identify potential areas of future research in this promising area of machine learning.
