2Deep: Enhancing Side-Channel Attacks on Lattice-Based Key-Exchange via 2-D Deep Learning

Advancements in quantum computing present a security threat to classical cryptography algorithms. Lattice-based key exchange protocols show strong promise due to their resistance to theoretical quantum-cryptanalysis and low implementation overhead. By contrast, their physical implementations have shown vulnerability against side-channel attacks (SCAs) even with a single power measurement. The state-of-the-art SCAs are, however, limited to simple, sequentialized executions of post-quantum key-exchange (PQKE) protocols, leaving the vulnerability of complex, parallelized architectures unknown. This article proposes 2Deep—a deep-learning (DL)-based SCA—targeting parallelized implementations of PQKE protocols, namely, <monospace>Frodo</monospace> and <monospace>NewHope</monospace> with data augmentation techniques. Specifically, we explore approaches that convert 1-D time-series power measurement data into 2-D images to formulate SCA an image recognition task. The results show our attack’s superiority over conventional techniques including horizontal differential power analysis (DPA), template attacks (TAs), and straightforward DL approaches. We demonstrate improvements up to <inline-formula> <tex-math notation="LaTeX">$1.5\times $ </tex-math></inline-formula> to recover a 100% success rate compared to DL with 1-D input data while using fewer data. We furthermore show that machine learning improves the results up to <inline-formula> <tex-math notation="LaTeX">$1.25\times $ </tex-math></inline-formula> compared to TAs. Furthermore, we perform cross-device attacks that obtain profiles from a single device, which has never been explored. Our 2-D approach is especially favored in this setting, improving the success rate of attacking <monospace>Frodo</monospace> from 20% to 99% compared to the 1-D approach. Our work thus urges countermeasures even on parallel architectures and single-trace attacks.
Photovoltaic enhancement of organic solar cells by a bridged donor-acceptor block copolymer approach

The authors show that a photovoltaic device composed of a -donor-bridge–acceptor-bridge- type block copolymer thin film exhibits a significant performance improvement over its corresponding donor/acceptor blend (Voc increased from 0.14to1.10V and Jsc increased from 0.017 to 0.058mA∕cm2) under identical conditions, where donor is an alkyl derivatized poly-p-phenylenevinylene (PPV) conjugated block, acceptor is a sulfone-alkyl derivatized PPV conjugated block, and bridge is a nonconjugated and flexible unit. The authors attribute such improvement to the block copolymer intrinsic nanophase separation and molecular self-assembly that results in the reduction of the exciton and carrier losses.
Electron doped Sr2IrO4−δ (0 ≤ δ ≤ 0.04): Evolution of a disordered Jeff = 1/2 Mott insulator into an exotic metallic state

Stoichiometric Sr2IrO4 is a ferromagnetic Jeff = [1/2] Mott insulator driven by strong spin-orbit coupling. Introduction of very dilute oxygen vacancies into single-crystal Sr2IrO4−δ with δ ≤ 0.04 leads to significant changes in lattice parameters and an insulator-to-metal transition at TMI = 105 K. The highly anisotropic electrical resistivity of the low-temperature metallic state for δ ≈ 0.04 exhibits anomalous properties characterized by non-Ohmic behavior and an abrupt current-induced transition in the resistivity at T* = 52 K, which separates two regimes of resistive switching in the nonlinear I-V characteristics. The novel behavior illustrates an exotic ground state and constitutes a new paradigm for devices structures in which electrical resistivity is manipulated via low-level current densities ∼ 10 mA/cm2 (compared to higher spin-torque currents ∼ 107–108 A/cm2) or magnetic inductions ∼ 0.1–1.0 T.
Cattle trading favors the introduction and establishment of the invasive tick Rhipicephalus (Boophilus) microplus in Menoua Division, West Region of Cameroon

Tick infestation is a major public health and veterinary issue that limits animal productivity throughout the world. Uncontrolled cattle movements during trading creates risks for introduction and rapid spread of ticks and tick borne pathogens in-to areas where previously absent. These movements are intense in the Western highlands of Cameroon and promote the circulation of ticks. Thus, the need to assess the abundance and distribution of tick vectors with the aim of establishing a baseline for monitoring future spread of tick borne diseases in the Menoua Division is urgent. A longitudinal study was carried out on 360 cattle selected at the Nkong-Ni municipal slaughterhouse for tick collection. All visible adult ticks were collected on each animal, preserved in 70% ethanol, counted and morphologically identified. The total of 8,492 adult ticks belonged to 14 species grouped into 5 genera. The relative abundance of the 3 most prominent species was Rhipicephalus decoloratus (50.6%), Amblyomma variegatum (25.0%) and Rhipicephalus microplus (7.6%). R. microplus was found on cattle all over the year and could be due to interconnection of herds through trade with an important relative abundance observed from October to January. Out of the 360 cattle examined, 312 (86.66%) were infested. Animals were 6 times more infested in the dry than in the rainy season with a relative risk of infestation greater in November, January and March compared to other months (p
Darstellung und Charakterisierung von Tetrabutylammonium-Tetraiodooxotechnetat(V), (TBA) [TcOI4] / Preparation and Characterization of Tetrabutylammonium Tetraiodooxotechnetate(V), (TBA)[TcOI4]

Abstract Pure (TBA)[TcOI4] is prepared from (TBA)[TcOCl4] by ligand exchange reaction with Nal in acetone. The vibrational spectra indicate C4v symmetry for the complex ion. On excitation with the 514.5 nm line of an Ar-laser a resonance Raman spectrum is obtained showing v(TcO) = 996 cm-1 and four of its overtones, symmetrically surrounded by groups of bands arising as well from the sums as from the differences of frequencies with the other fundamentals. In contrast to the ligand exchange reaction the reduction of Tc04- with conc. HI yields products always contaminated with polyiodides. The extremely strong Raman scatterer (TBA)l3 is detected by a characteristic doublet at 111 and 116 cm-1 and even small amounts of it cover the Raman spectrum of (TBA)[TcOI4].
Data anomaly detection and Data fusion based on Incremental Principal Component Analysis in Fog Computing

The intelligent agriculture monitoring is based on the perception and analysis of environmental data, which enables the monitoring of the production environment and the control of environmental regulation equipment. As the scale of the application continues to expand, a large amount of data will be generated from the perception layer and uploaded to the cloud service, which will bring challenges of insufficient bandwidth and processing capacity. A fog-based offline and real-time hybrid data analysis architecture was proposed in this paper, which combines offline and real-time analysis to enable real-time data processing on resource-constrained IoT devices. Furthermore, we propose a data process-ing algorithm based on the incremental principal component analysis, which can achieve data dimensionality reduction and update of principal components. We also introduce the concept of Squared Prediction Error (SPE) value and realize the abnormal detection of data through the combination of SPE value and data fusion algorithm. To ensure the accuracy and effectiveness of the algorithm, we design a regular-SPE hybrid model update strategy, which enables the principal component to be updated on demand when data anomalies are found. In addition, this strategy can significantly reduce resource consumption growth due to the data analysis architectures. Practical datasets-based simulations have confirmed that the proposed algorithm can perform data fusion and exception processing in real-time on resource-constrained devices; Our model update strategy can reduce the overall system resource consumption while ensuring the accuracy of the algorithm.
The Determinant of Household Welfare Beneficiaries of Food Social Assistance

Welfare is the satisfaction obtained by someone from consuming the income received. The problem of food security is food insecurity or food insecurity is closely related to welfare and experienced by poor households. The purpose of this study was to analyze the impact of food social assistance on beneficiary families' welfare in Sabang City. This study uses primary data obtained from interviews and observations of 50 beneficiary families of food social assistance. Secondary data obtained from the Central Statistics Agency and the National Logistics Agency of Aceh Province. The study uses a quantitative multiple regression approach and a descriptive qualitative approach to primary data. The results showed that food social assistance, rice consumption, non-food social assistance had a positive effect on welfare. Beneficiary families who do not have bank loans will be more prosperous by half of their welfare compared to KPM who have bank loans
Uncertainties in data on organic aerosols

Organic aerosols are gaining increasing attention because of their importance in studies ofradiative forcing of climate. However, there is a potential for large and unquantified biases inmost of the published data, which has been derived using variations on the evolved gas analysismethod (EGA). We argue that the magnitude of these putative uncertainties makes it impossibleboth to test hypotheses concerning the variation of organic carbon (OC) with altitude and todevelop realistic models of radiative climate forcing.

Sequential introduction of three electrophiles into 1,3,5-tribromobenzene based on Br/Li exchange reaction was achieved using an integrated flow microreactor system consisting of six micromixers and six microtube reactors. This method enables flash synthesis of TAC-101 and its analogues within 13 s in good yields on a preparative scale.
Problems of Ukraine’s integration into the European Union

Purpose: The purpose of the article is to establish the place of Ukraine on the process of European integration and the identification of obstacles to full membership in the European Union. Design/methodology/approach: The methodological and theoretical basis of the article is the fundamental provisions of economic theory, the works of scientists and economists in the field of international economic relations and integration. Findings: The article explores the problems of Ukraine’s integration into the EU. The study analyzed the attitude of Ukrainians towards European integration, identified the main arguments for and against accession to the EU countries, as well as the main internal and external threats of the integration process. It has been determined that in recent years the proportion of the population that has supported Ukraine’s accession to the EU has significantly increased. From the integration into the EU, Ukrainians primarily expect to expand the space of their own capabilities and the country's internal development in accordance with modern world trends. It is concluded that the population considers a high level of corruption in the country, problems in the Donbass and the inefficiency of public administration as the main obstacles to this process. Most residents of Ukraine consider it necessary to implement European reforms, but the consequence of their implementation has identified significant problems in terms of their real social effect. It is determined that Ukraine in some macroeconomic indicators lags significantly behind the EU countries, continues to lose its position in the global ranking of countries in terms of economic competitiveness, and remains one of the poorest countries in Europe. A significant problem for the development of Ukraine is the labor migration of the population and, in particular, the increase in the number of illegal migrants Ukrainians in Europe. The main achievements in the implementation of the Association Agreement between Ukraine and the EU are analyzed and the main threats to the further European integration are identified. It is concluded that Ukraine needs to develop its own “action plan” for the possibility of realizing national interests, taking into account the interests of the parties involved in the integration process. Originality/value: The mood of Ukrainian society, the current position of the state, the main obstacles and priorities that Ukraine faces on the way to the EU have been analysed in detail.
Effect of Ralstonia solanacearum on Mineral Nutrients and Infrared Temperatures in Two Tomato Cultivars

ABSTRACT The objective of this study was to determine how the responses of two tomato cultivars to Ralstonia solanacearum relate to their leaf infrared temperature and acquiring of nutrients from soil. Tomato (Solanum lycopersicum L.) cultivars of disease susceptible-‘FL 47’ and resistant-‘H 7998’ were grown in soil inoculated with R. solanacearum. Bacterial wilt incidence, leaf infrared temperatures, and uptake of nutrients were measured for 28 d. In bacterial wilt-resistant cultivar ‘H 7998’, concentration of sulfur (S; +77%), calcium (Ca; +66%), boron (B; +60%) were found higher and nitrogen (N; −26%) were found lower, compared with susceptible ‘FL 47’. Infrared temperatures were correlated with wilt percentage at 14 d, but not at 7 d. These results provide evidence that there is a correlation between bacterial wilt resistance and translocation of some nutrients in the shoots. Additionally, data indicates that the infrared thermometer could only detect wilting after obvious symptoms were visibly incited by R. solanacearum in tomato.
Tratamento anaeróbio de pentaclorofenol em reator de leito fluidificado alimentado com água residuária sintética contendo glicose como fonte única de carbono

In the present work, an anaerobic fluidized bed reactor (AFBR) was used for the treatment of a synthetic wastewater containing pentachlorophenol (PCP) subjected to less idealized operating conditions. The reactor was a 16 litres tank with granular activated carbon particles as support media. Evaluation of AFBR performance was done by the analysis of usual monitoring parameters (pH, alkalinity, COD, volatile acids) together with microscopy and PCP concentration analysis. The presence of PCP under the concentrations used did not significantly alter the amount of biomass and the performance monitoring parameters. Removal average efficiencies of the order of 92% and 70% were obtained for PCP inflow concentrations in the range of 1 to 6mg/l.
Characterization of an Oil Spill Along the Lebanese Coast by Satellite Images

The Lebanon population witnessed a severe environmental problem when one of the country's largest coastal power stations in Jiyeh area was bombed on July 13, 2006. Several million gallons of fuel oil were released into the Mediterranean Sea, forming a huge oil spill. To assess the extent of the spill, two types of satellite images were used. First, the moderate resolution imaging spectroradiometer (MODIS)-Terra images were obtained in near real-time immediately following the event and second advanced space-borne thermal emission and reflection radiometer (ASTER) images were taken about 1 month later. Results showed an oil plume with areal extent of approximately 3,100 km2 shortly after the event, reaching the northern coast of Lebanon. However, after 2 months, satellite monitoring showed the geographic distribution of oil was reduced to 185 km2. The bio-environmental impact of this oil spill, due to its size and hydraulic dynamics, makes a major disaster.
Deviations from linear Stern–Volmer law in hopping quenching theory

The differential and integral binary theories of hopping quenching were used to calculate the quenching kinetics, its stationary rate, and the luminescence quantum yield assuming Markovian random walk of excitation and dipole–dipole energy transfer to acceptors. It is shown that the integral theory results are not valid for high concentration of acceptors, however, its kernel (mass operator) is defined. On the contrary, the differential theory which is exact for immobile donors as well as so‐called Burshtein model, which is appropriate for immobile acceptors, are at least the useful interpolations between binary ‘‘migration accelerated quenching’’ (MAQ) limit and multiparticle in principle ‘‘static quenching’’ limit.
Building and Using Personal Knowledge Graph to Improve Suicidal Ideation Detection on Social Media

A large number of individuals are suffering from suicidal ideation in the world. There are a number of causes behind why an individual might suffer from suicidal ideation. As the most popular platform for self-expression, emotion release, and personal interaction, individuals may exhibit a number of symptoms of suicidal ideation on social media. Nevertheless, challenges from both data and knowledge aspects remain as obstacles, constraining the social media-based detection performance. Data implicitness and sparsity make it difficult to discover the inner true intentions of individuals based on their posts. Inspired by psychological studies, we build and unify a high-level suicide-oriented knowledge graph with deep neural networks for suicidal ideation detection on social media. We further design a two-layered attention mechanism to explicitly reason and establish key risk factors to individual's suicidal ideation. The performance study on microblog and Reddit shows that: 1) with the constructed personal knowledge graph, the social media-based suicidal ideation detection can achieve over 93% accuracy; and 2) among the six categories of personal factors, post, personality, and experience are the top-3 key indicators. Under these categories, posted text, stress level, stress duration, posted image, and ruminant thinking contribute to one's suicidal ideation detection.
Response of a Tropical Reservoir to Bubbler Destratification

A one-dimensional reservoir-bubbler model has been developed to examine the mixing and the change in dissolved oxygen pattern induced by bubbler operation in a stratified reservoir. The reservoir-bubbler model is applied to a tropical reservoir, the Upper Peirce Reservoir, Singapore. For this tropical reservoir with low wind speeds, it is found that bubbler operation dominates oxygen transfer into the reservoir water rather than oxygen transfer from all other sources, including surface reaeration. It is illustrated that selection of airflow rate per diffuser, air bubble radius, and total number of diffusers are important criteria in bubbler designs. Higher dissolved oxygen levels in reservoirs are obtained by increasing the bubbler airflow rate that is associated with lower mechanical efficiency ( ηmech ) than optimal ηmech of the bubbler. Determining an appropriate airflow rate is shown to be a tradeoff between increased dissolved oxygen levels and increased operating costs as airflow rate increases. Whe.
Controllable stripping of radiolabeled group in vivo to optimize nuclear imaging via NO-responsive bioorthogonal cleavage reaction

A novel “turn-off” strategy for controllable radionuclide clearance is established. 1,4-dihydropyridine (DHP) is used as a conditional linker to connect a radioisotope labeled moiety and nano-agent. A highly specific, sensitive and effective C–C bond cleavage of DHP happens in vivo when treated with nitric oxide which is provided by glyceryl trinitrate (GTN). The radioactive cut-off part from the nanoparticle is observed to be cleared quickly by microSPECT-CT. 3–5 times decreases of radioactivity in the blood, kidneys, intestine, heart and lungs are observed after GTN treatment in a biodistribution assay. The radioactivity redistribution indicates that the radioactive leaving part is indeed cut off and the radionuclide metabolism accelerated. Organ level internal dose assessment reveals the GTN treated groups carry only ½ the radiation dose of the control group. Collectively, a feasible pathway for controllable radionuclide clearance is for the first time provided for high contrast and low radiation nuclear imaging.
A METHOD FOR EVALUATING MECHANISTIC ASPECTS OF CHEMICAL MIXTURE TOXICITY

A method for relating mixture toxicity models and mechanisms of action has been developed. The approach utilizes a 1.2-factor matrix design to generate seven binary mixture concentration-response curves. The X 2 goodness-of-fit test is used to compare the experimental responses to the theoretical effects calculated for the dose-addition and independence models. In testing, induction of osteolathyrism in Xenopus embryos was the response evaluated. Testing was for 96-h with daily solution removal and replacement. Analysis of the response curves indicated that thiosem icarbazide (TSC) and semicarbazide (SC) induced osteolathyrism in a dose-additive manner. Along with the similarity in chemical structures, the results indicate, in theory, that TSC and SC disrupt connective tissue cross-linking in the notochord by the same specific mechanism. The results support further evaluation of the method.
Influence of Root Morphology on Ecological Slope Protection

Ecological slope protection is of great importance for preventing the water and soil loss on bare slopes, improving the ecological environment, and realizing the sustainable ecosystem development. The root-soil composite slope consisting of homogenous soil mass and oleander root system was taken as the study object. Based on the mechanics principle of soil reinforcement by roots in ecological slope protection, the influences of the lateral root quantity of plants and included angle between main root and lateral root on the slope protection were investigated via the finite element (FE) software ABAQUS. The simulation results show that the larger the quantity of lateral roots, the more obvious the displacement reduction of the soil mass on the slope surface will be. The slope protection effect varies with the root morphology, the included angle between main root and lateral root is an important factor influencing the slope protection effect of plants, and the slope protection effect at included angle of 30° is apparently superior to that at 90°. The research results can provide a theoretical support for the plant selection in the ecological slope protection.
In Vitro Differentiation of Adipose-Derived Mesenchymal Stem cells into Cardiac Tissue-Linked Progenitor Cell Cluster Using Fibrin Matrix Based Niche

Human adipose-derived mesenchymal stem cells (hADMSCs) transplantation has been widely explored for restoring post-myocardial infarct heart function, with limited success. Whereas the multipotent nature of hADMSC could benefit regeneration, differentiation into undesired lineages upon transplantation could detriment the effects. Therefore, controlled in vitro lineage commitment of hADMSC into cardiac cells, before transplantation offers a promising strategy towards better tissue regeneration. The function of cardiac tissue may require a coordinated action of mixed cell types such as cardiomyocyte-like cells (CMLs), endothelial-like cells (ELCs), and cardiac fibroblast-like cells (CFLs). Therefore, as a preliminary step for developing autologous cell-based therapy, this study derived CMLs, CFLs, and ELCs from hADMSCs of cardiovascular disease (CVD) patients. Specifically designed fibrin-based niche aided the lineage commitment of hADMSCs into different cardiac cells. At least two specific markers of each cell type, both at mRNA and protein level, are demonstrated. The co-culturing of hypoxia-induced additional ELC with co-developed CML-CFL-ELC resulted in further upregulation of cardiogenic and angiogenic markers at the transcriptional level. The study confirms the advantage of multipotency of hADMSCs from CVD patients and the designed niche conditions for obtaining viable mixed population cardiac progenitors for potential benefits in individualized MI regeneration approaches.
