Hardware-Accelerated Cryptography For Software-Defined Networks

: This paper presents a Software-Deﬁned Network (SDN) cryptographic solution targeted on high-speed smart Network Interface Cards (NICs) with an FPGA chip. This solution provides a fast alternative method to develop network-oriented data processing cryptography applications for an accelerator. A high-level programming language – Programming Protocol-independent Packet Processor (P4) – is used to avoid a complex and time-consuming hardware development. The solu-tion consists of two main parts: a library of mainly used cryptographic primitives written in VHSIC Hardware Description Language (VHDL) i.e. a symmetric cipher (AES-GCM-256), a hash function (SHA-3), a SHA-3-based Hash-based Message Authentication Code (HMAC), a digital signature scheme (EdDSA) and a post-quantum digital signature scheme (Dilithium), and a compiler P4/VHDL with the support for these cryptographic components as external objects of P4 16 .
A Multiwavelength Campaign on γ Cassiopeiae. II. The Case for Corotating, Circumstellar Clouds

Simultaneous X-ray/UV observations over a full day on 1996 March 14-15 have been made of the prototypical B0.5e star γ Cas using the Rossi X-Ray Timing Explorer satellite and the Goddard High Resolution Spectrograph (GHRS) on board the Hubble Space Telescope. The GHRS spectra, taken in the region of the Si IV λλ1394-1403 doublet, also permitted the construction of an extremely precise light curve from a nearby "pseudocontinuum" region. The continuum UV and X-ray light curves reveal a pair of X-ray maxima ~10 hr apart that coincide in time with UV continuum flux "dips" of ~1%. In the first paper in this series we attributed the long-term X-ray variations to magnetic activity sites on the surface of the star that undergo rotational modulation on a ~1.125 days period. In the current study we find that flux and color curves generated from a 33 hr sequence of International Ultraviolet Explorer (IUE) echellegrams obtained in 1996 January display dip features similar to those in the GHRS data. Comparing the timings of the continuum flux dips and the Si IV line strength variations in both the GHRS and IUE data sets gives a slightly revised period of 1.123 days for both the UV and X-ray activities. This strengthens the argument that high-energy activity on γ Cas is modulated by rotation of long-lived structures close to its surface. Analysis of the pseudocontinuum light curves constructed from the GHRS and IUE light curves shows at least two surprising characteristics for the flux dips: (1) the dips last only ~0.3 cycles, which is too brief for rotation modulation of surface features, and (2) their amplitudes increase from long to short wavelengths, which attain a maximum near 1206 Å. The character of the variations of the photospheric Si IV line profiles is unexpected in that the equivalent width fluctuations do not correlate with the slow undulations of the continuum flux. Moreover, the profile variations do not show an expected blue-to-red migration of microfeatures. We show that the continuum characteristics and absence of migration of features in the Si IV lines can be explained by the presence of very cool, optically thin clouds that corotate with the star. Assuming a tilt of the rotational axis of +45° to the observer's line of sight, our model simulations of the two major dips in the UV light curves indicate that the clouds have radii of a few tenths of a stellar radius and are attached to points on the surface at low to mid-latitudes on the near hemisphere. These findings support the conclusion of the first paper in this series that γ Cas is a member of a small group of OB stars that have magnetospheres associated with X-ray activity.
Fundamental Involutory Root Systems and a Branching Theorem for Symmetric Pairs

Let 𝔤 be a complex semisimple Lie algebra with an involutory automorphism θ. Let 𝔨 be the corresponding symmetric subalgebra and 𝔥 be a fundamental Cartan subalgebra of 𝔤 containing a Cartan subalgebra 𝔱 of 𝔨. Let Δ(𝔤, 𝔥) and Δ(𝔤, 𝔱) be the respective root systems of 𝔤 with respect to 𝔥 and 𝔱. The pair (Δ(𝔤, 𝔥), θ) is a fundamental involutory root system. We prove that there exists natural 1-1 correspondences between θ-stable Weyl chambers of Δ(𝔤, 𝔥) and Weyl chambers of Δ(𝔤, 𝔱) and that the Weyl group of Δ(𝔤, 𝔱) acts simply transitively on the above two sets of Weyl chambers. Regard a finite dimensional complex irreducible 𝔤-module V as a 𝔨-module, based on the above results we show that some certain irreducible modules of 𝔨 will occur in V.
Perception of the proximal voice features for emotional speech

The expression of emotions results in a number of changes to the acoustic signal. Considering that prosodic events may be encoded into the speech signal using multiple acoustic features, many acoustic variations may be redundant for listeners. An understanding of the acoustic changes that listeners can reliably use to differentiate emotional speech will help in the modeling emotions, for example, from a Brunswikian perspective. In the Brunswikian model of emotion communication, the acoustic features are represented as “distal cues” and the subjective perception of these changes are represented as “proximal percepts. ” Few attempts have been made to understand the proximal percepts of emotional speech in relation to the acoustic properties they represent. In this study, 19 listeners were asked to rate a set of 160 samples (2 sentences expressed in 8 emotions by 10 speakers) using 12 visual-analog scales (8 prosodic scales and 4 emotion dimensions). Results showed high reliability for all scales except rough.
Design of optical frequency comb for sky survey astronomical spectrograph calibration

Sky survey telescope is an important approach to ground-based observation of external galaxies, and further research on large-scale structure of the universe, galaxy formation and evolution. Sky survey spectrograph (SSS) with low resolution is included in such kind of telescope system. The spectral measurement accuracy of SSS will determine the accuracy and scientific value of mass spectral data. Currently iodine absorption cell or Thorium-Argon lamp is adopted as the calibration source for SSS. However, the spectral lines are sparse, with non-uniform spectral interval and intensity, and even instable over long time. The novel astro-comb cannot be applied to SSS directly because the spectral intervals are still too dense to be used in SSS with relatively lower resolution. In this paper, spectral mode filtering method with acceptable energy reduction and accurate spectral line frequency is studied to improve current astro-comb to properly distributed spectral lines and solve the above critical problem. Aiming at calibration for the measuring of the spectral lines in 3700-5900 Å region, we design an improved astro-comb system based on Erbium-doped fiber laser and Fabry-Perot filter series. Feasible systematical parameters are given. It will help develop a novel calibration approach with systematic error reduction to less than 1/10000 of that of the current calibration methods.
Effect of texture on damping behaviour in ZK60 magnesium alloy

ABSTRACT Effect of texture on the damping capacity of ZK60 magnesium alloy is investigated through compression experiments with a deformation of 10% at room temperature. It is found that both the dislocation networks, twins and the basal texture intensity affect the damping capacity. At the low strain amplitudes, the dislocation networks and twins are dominant and the damping capacity decreases with the increase in the dislocation networks and twins. At the high strain amplitudes, the basal texture intensity is dominant and the damping capacity decreases with the increase in the basal texture intensity. Based on the anisotropy of the damping capacity of the wrought magnesium alloys, this research provides provide a direction for the study of high-strength and high-damping magnesium alloys.
Spectral analysis in magnetohydrodynamic equilibria

It has been universally assumed that the spectrum of the magnetohydrodynamics equations, linearized around an equilibrium state, provides enough information on the short-term evolution of the plasma to study certain stability properties. We show that this is true if one takes into account viscous and resistive effects and the equilibrium satisfies certain regularity conditions.
College students’ anxiety after returning to school during the COVID-19 epidemic: What should we care

The college students’ anxiety during the Coronavirus disease 2019 (COVID-19) epidemic remains unclear. We aimed to evaluate the college students’ anxiety after returning to school during the COVID-19 epidemic, to provide reference for the management and nursing care of college students. We conducted a survey from September 15, 2021 to September 30, 2021 investigate the anxiety level of college students. The Self-rating Anxiety Scale was used for anxiety assessment. The Spearman correlation analysis was conducted to evaluate the correlation between students’ anxiety and characteristics. Logistic regression analysis was used to explore the influencing factors of concurrent anxiety among college students. A total of 2168 college students were included, the incidence of anxiety was 30.07% in college students during the COVID-19 epidemic. Pearson correlation analyses showed that grade (R = 0.715), main use of computer and mobile phone (R = 0.622), daily exercise (R = 0.735), whether relatives or friends are infected with COVID-19 (R = 0.735) are associated with the anxiety level of college students (all P < .05). Logistic regression analysis indicated that senior year (Odds ratio [OR] = 2.064, 95% confidence interval [CI]: 1.355–3.001), online game (OR = 3.122, 95% CI: 2.562–3.899), relatives or friends are infected with COVID-19 (OR = 2.987, 95% CI: 1.901–3.451) are the independent risk factors of anxiety in college students (all P < .05). Daily exercise (OR = 0.514, 95% CI: 0.205–0.814) was the independent protective factors of anxiety in college students (P = .008). During the COVID-19 epidemic, college students have increased anxiety and there are many influencing factors. Administrators and educators should especially pay attention to the mental health of students with those risk factors to maintain students’ physical and mental health.
FFAST mission to study the evolution of the universe in hard x-ray

A “formation flight astronomical survey telescope” (FFAST) is a new project that will cover a large sky area in hard X-ray. In particular, it will focus on the energy range up to 80 keV. It consists of two small satellites that will go in a formation flight. One is an X-ray telescope satellite carrying a “super mirror” and the other is a detector satellite carrying an SDCCD. Two satellites are put into a low earth orbit. They are in a formation flight with a separation of 20 m. Since two satellites are put into Keplerian orbit, the observation direction is moving the sky rather than pointing to a fixed direction. This project will survey a large sky area at hard X-ray region to study the evolution of the universe.
A Simplified Scheme to Simulate Asymmetries Due to the Beta Effect in Barotropic Vortices

Abstract A simplified scheme to generate vortex asymmetries due to the beta effect from an initially symmetric vortex on a beta plane is described. This approach, based on the time integration of the nondivergent barotropic vorticity equation, was developed to generate asymmetric vortex structure for inclusion in the initial conditions for the GFDL Hurricane Model. The simplification is derived from truncation of an azimuthal wavenumber expansion of the vorticity field variables. In order to determine the optimum lowest-order system, the influence of other wavenumbers (specifically 0, 2, and 3) on the asymmetric dipolar (wavenumber 1) structure and the associated vortex drift was investigated by comparing the results of a hierarchy of models differing in truncation level. The model truncated at wavenumber 2 and, including time-dependent symmetric flow, was chosen as the optimum system. Vortex drift tracks computed with this model compare very well with existing numerical model simulations. The models with.
Plant‐based diets could ameliorate the risk factors of cardiovascular diseases in adults with chronic diseases

Abstract Adherence to plant‐based diets is recommended to prevent and control chronic diseases. However, not all plant‐based foods are healthy for this purpose. This study investigated the relationship between plant‐based diets and risk factors for cardiovascular diseases (CVDs) in adults with chronic diseases. This cross‐sectional study was performed on 3678 males and females (age range: 40–70 years) with chronic diseases who participated in the Kharameh cohort study. A validated semiquantitative food‐frequency questionnaire was used to calculate the plant‐based diet index (PDI), healthy plant‐based diet index (hPDI), and unhealthy plant‐based diet index (uPDI). Lipid profile, fasting blood sugar (FBS), blood pressure, and anthropometric indices were measured. Multivariable‐adjusted logistic regression analysis was performed to determine the association between plant‐based diets and CVDs risk factors. Higher adherence to the PDI was inversely associated with the level of FBS (odds ratio [OR] = 0.42; 95% confidence interval [CI]: 0.33–0.53; p < .001). A significant decrease was observed for total cholesterol in those with higher adherence to hPDI (OR = 0.80; 95% CI: 0.65–0.98; p = .035). Additionally, the score of uPDI was positively related to FBS (OR = 1.23; 95% CI: 1.00–1.53; p = .01), total cholesterol (OR = 1.23; 95% CI: 1.01–1.49; p = .061), and low‐density lipoprotein (OR = 1.39; 95% CI: 1.13–1.71; p = .009). It was concluded that adherence to PDI and hPDI was related to a lower level of FBS and total cholesterol, respectively. Moreover, the findings suggested that regular intake of the uPDI was correlated with some risk factors for CVDs in adults with chronic diseases.
Entrainment into a Stratocumulus Layer with Distributed Radiative Cooling

Abstract It is shown that the radiative cooling of a cloud layer strongly influences the turbulent flux profiles and the entrainment rate, and that the radiative cooling should be modeled as acting inside the turbulent layer. Numerical experiments demonstrate that a cloud-topped mixed-layer model, similar to that of Lilly (1968), is quite sensitive to δpR, the depth of the radiatively cooled layer near cloud top. As δpR increases, the model’s sensitivity to the entrainment assumption is markedly heightened. More specifically, for large δpR the cloud top and cloud base rise dramatically as the entrainment parameter k is increased, while for small δpR an increase in k has almost no effect. The model is most sensitive to ΔpR precisely for the cold-water, strong-divergence regime of greatest interest.
The ubiquitin-like protein Hub1/UBL-5 functions in pre-mRNA splicing in Caenorhabditis elegans

The ubiquitin‐like protein Hub1/UBL‐5 associates with proteins non‐covalently. Hub1 promotes alternative splicing and splicing of precursor mRNAs with weak introns in yeast and mammalian cells; however, its splicing function has remained elusive in multicellular organisms. Here, we demonstrate the splicing function of Hub1/UBL‐5 in the free‐living nematode Caenorhabditis elegans. Hub1/UBL‐5 binds to the HIND‐containing splicing factors Snu66/SART‐1 and PRP‐38 and associates with other spliceosomal proteins. C. elegans hub1/ubl‐5 mutants die at the Larval 3 stage and show splicing defects for selected targets, similar to the mutants in yeast and mammalian cells. UBL‐5 complemented growth and splicing defects in Schizosaccharomyces pombe hub1 mutants, confirming its functional conservation. Thus, UBL‐5 is important for C. elegans development and plays a conserved pre‐mRNA splicing function.
The equilibria and evolutions of magnetized, rotating, isothermal clouds. IV. Quasi-static evolution

The evolution of a rotating magnetized cloud is studied using a numerical method and a quasi-static assumption. The angular momentum loss rate is discussed, including the critical value of the mass-to-flux ratio at which point the cloud begins to collapse dynamically. The difference between the present case and a plane-parallel cloud is examined. 34 refs.
Opportunities and Challenges of Advanced Practice Midwifery (APM) in Kenya: A Discussion Paper

Background: The high maternal and neonatal deaths remain a global concern especially in Low- and Middle-Income Countries. This is largely attributed to the limited skilled workforce including midwives who are required to offer quality maternal and neonatal care. Advanced Practice Midwifery (APM) training has been highlighted as critical in achieving high-quality maternal and neonatal care in all settings and countries. In Kenya, the APM training is at the initial stages, having been launched in May 2022. This paper presents the results of a literature review regarding opportunities and challenges for the APM training and practice with a goal of availing information to any institution willing to begin the program in Kenya and other LMICs. Methodology: A descriptive overview was undertaken through a rapid literature review of the relevant local and international literature to highlight the opportunities and challenges for the APM training and practice based on the Kenyan Context. Results: The APM training and practice has expansive opportunities such as the increased demand for quality care and reduced cost services, supportive policies, advances in technology, profession recognition and regularisation of the training and availability of midwives trained at lower levels. The challenges that the APM training is likely to experience includes; Lack of expert trainers, technological challenges, workload challenges due to the high population in need of the services and clinical environment challenges. Conclusion: APM training and practice has enormous opportunities despite the challenges that may be experienced. Therefore, for any institution preparing to start the APM training, there is need to exploit the existing opportunities and address the likely challenges to ensure the APM training and practice meets the desired outcomes.
Recent Trends and Developments in Multifunctional Nanoparticles for Cancer Theranostics

Conventional anticancer treatments, such as radiotherapy and chemotherapy, have significantly improved cancer therapy. Nevertheless, the existing traditional anticancer treatments have been reported to cause serious side effects and resistance to cancer and even to severely affect the quality of life of cancer survivors, which indicates the utmost urgency to develop effective and safe anticancer treatments. As the primary focus of cancer nanotheranostics, nanomaterials with unique surface chemistry and shape have been investigated for integrating cancer diagnostics with treatment techniques, including guiding a prompt diagnosis, precise imaging, treatment with an effective dose, and real-time supervision of therapeutic efficacy. Several theranostic nanosystems have been explored for cancer diagnosis and treatment in the past decade. However, metal-based nanotheranostics continue to be the most common types of nonentities. Consequently, the present review covers the physical characteristics of effective metallic, functionalized, and hybrid nanotheranostic systems. The scope of coverage also includes the clinical advantages and limitations of cancer nanotheranostics. In light of these viewpoints, future research directions exploring the robustness and clinical viability of cancer nanotheranostics through various strategies to enhance the biocompatibility of theranostic nanoparticles are summarised.
A Discrete Elements Study of the Frictional Behavior of Fault Gouges

A series of discrete elements simulations is presented for the study of fault gouges' frictional response. The gouge is considered to have previously undergone ultra‐cataclastic flow and long‐time consolidation loading. We explore the effect of different particle characteristics such as size, polydispersity, and also shearing velocities on gouge's response under the conditions met in the seismogenic zone. Monte‐Carlo analyses suggest that the local stick‐slip events disappear when averaging over a large number of numerical samples. Moreover, the apparent material frictional response remains almost unaffected by the spatial randomness of particles' position and by the particle's size distribution. On the contrary, the mean particle size controls the formation and thickness of the observed shear bands, which appear after the peak friction is met. Furthermore, the apparent friction evolution fits well to an exponential decay law with slip, which involves a particle size dependent critical slip distance. For the studied conditions and depth, the shearing velocity is found to play a secondary role on the apparent frictional response of the gouge, which highlights the importance of analyses involving multiphysics for studying the rheology of fault gouges. Besides improving the understanding of the underlying physics of the problem, the above findings are also useful for deriving pertinent constitutive models in the case of modeling with continuum theories.
Phytoprofiling of Sorbus L. Inflorescences: A Valuable and Promising Resource for Phenolics

The leaves and fruits of various Sorbus L. genotypes have long ethnopharmacological and food-usage histories, but inflorescences are still underutilized and neglected materials with scarce phytochemical scientific evidence. The aim of this study was to determine the phenolic profiles of inflorescence extracts of 26 Sorbus species, genotypes, and cultivars. HPLC and UPLS with MS detection were applied, and coupled data revealed unique phytochemical phenolic profiles. Neochlorogenic and chlorogenic acids were the key compounds, reaching up to 5.8 mg/g of dw. Rutin, isoquercitrin, quercetin 3-O-malonylglucoside, isorhamnetin 3-O-rutinoside, sexangularetin derivative, and kaempferol acetyl hexoside were detected in all Sorbus inflorescence samples. Overall, high quantitative heterogeneity across the various Sorbus genotypes was found by profiling. Phenolic fingerprint profiles and sexangularetin derivatives could serve as markers in authenticity studies and quality control schemes. The species S. amurensis, S. arranensis, S. commixta, and S. discolor and the cultivars ‘Chamsis Louing’, ‘Coral Beauty’, and ‘Edulis’ could be used as target genotypes for production of smart and innovative inflorescence matrix-based ingredients.
Integrated production scheduling and preventive maintenance planning for a single machine under a cumulative damage failure process

This paper finds the optimal integrated production schedule and preventive maintenance plan for a single machine exposed under a cumulative damage process, and investigates how the optimal preventive maintenance plan interacts with the optimal production schedule. The goal is to minimize the total tardiness. The optimal policy possesses the following properties: Under arbitrary maintenance plan when jobs have common processing time, and different due dates, the optimal production schedule is to order the jobs by earliest due date first rule; and when jobs have common due date and different processing times, the optimal production schedule is shortest processing time first. The optimal maintenance plan is of control limit type under any arbitrary production schedule when machine is exposed under a cumulative damage failure process. Numerical studies on the optimal maintenance control limit of the maintenance plan indicate that as the number of jobs to be scheduled increases, the effect of jobs due dates on the optimal maintenance control limit diminishes. © 2007 Wiley Periodicals, Inc.
