Convolutional Model with a Time Series Feature Based on RSSI Analysis with the Markov Transition Field for Enhancement of Location Recognition

Although numerous schemes, including learning-based approaches, have attempted to determine a solution for location recognition in indoor environments using RSSI, they suffer from the severe instability of RSSI. Compared with the solutions obtained by recurrent-approached neural networks, various state-of-the-art solutions have been obtained using the convolutional neural network (CNN) approach based on feature extraction considering indoor conditions. Complying with such a stream, this study presents the image transformation scheme for the reasonable outcomes in CNN, obtained from practical RSSI with artificial Gaussian noise injection. Additionally, it presents an appropriate learning model with consideration of the characteristics of time series data. For the evaluation, a testbed is constructed, the practical raw RSSI is applied after the learning process, and the performance is evaluated with results of about 46.2% enhancement compared to the method employing only CNN.
Determination of critical energy criteria for hexanitrostilbene using laser-driven flyer plates

Laser-driven flyer plates comprise of one or more thin layers forming a foil coated onto a transparent substrate. Irradiation of the foil/substrate interface with a Q-switched laser pulse produces a plasma, the expansion of which forms a flyer plate, which can reach velocities in excess of 5 km/s. These plates impart shocks in excess of 50 GPa, with duration of less than a nanosecond. This shock is sufficient to initiate secondary explosives such as Hexanitrostilbene (HNS) and Pentaerythritol Tetranitrate (PETN). Thresholds of detonators based on laser-driven flyer plates are typically measured in terms of energy. By using a Photonic Doppler Velocimeter (PDV) we measure the velocity of the flyer plate at the threshold energy. This allows calculation of the shock pressure and duration imparted to the explosive. By initiating HNS with a variety of flyer thicknesses, from 3 to 5 &mgr;m, we are able to evaluate Pn&tgr; in this extreme shock regime. The calculated value of n is compared to published values and discussed for similar systems. We are also able to use the James Criterion to analyze the initiation, with values of Ec and &Sgr;c being determined from experimental data, providing a predictive capability to model other configurations such as different flyer thicknesses and materials.
Australia Telescope Compact Array Observations of Radio Recombination Lines toward 30 Doradus

Three hydrogen recombination lines—H90α at 8.9 GHz, H92α at 8.3 GHz, and H109α at 5.0 GHz—have been observed with the Australia Telescope Compact Array toward the 30 Doradus Nebula, the giant H II region in the Large Magellanic Cloud. In this paper, emphasis is placed on the more sensitive H90α observations, which also include the He90α and H113β lines. A spatial resolution of 15'' was obtained with a velocity resolution of 4.2 km s-1 and an rms noise of 1.6 mJy. Typical line-to-continuum ratios were 0.04 for the H90α and H92α, and 0.03 for the H109α data. The distributions of radial velocity and electron temperature have been determined. The heliocentric velocity of the ionized gas varies between 245 and 290 km s-1 with a mean value of 262 km s-1. In some places the line profile is double, suggesting that sections of expanding shells are being observed. The mean (LTE) electron temperature is close to 7700 K over most of the nebula. The intensity ratio of H113β/H90α is close to the expected LTE value of 0.28, implying that the calculated LTE electron temperatures are close to the true electron temperatures; in one area to the north the ratio is enhanced, 0.39 ± 0.03. The helium abundance (Y+ = He+/H+) shows no significant variation across the source, with a mean value of 0.13 ± 0.02.
Different Designs of Deep Marginal Elevation and Its Influence on Fracture Resistance of Teeth with Monolith Zirconia Full-Contour Crowns

Background and objectives: Even with the demand for high esthetics, the strength of the material for esthetic applications continues to be important. In this study, monolith zirconia (MZi) crowns fabricated using CAD/CAM were tested for fracture resistance (FR) in teeth with class II cavity designs with varying proximal depths, restored through a deep marginal elevation technique (DME). Materials and Methods: Forty premolars were randomly divided into four groups of ten teeth. In Group A, tooth preparation was conducted and MZi crowns were fabricated. In Group B, mesio-occluso-distal (MOD) cavities were prepared and restored with microhybrid composites before tooth preparation and the fabrication of MZi crowns. In Groups C and D, MOD cavities were prepared, differentiated by the depth of the gingival seat, 2 mm and 4 mm below the cemento-enamel junction (CEJ). Microhybrid composite resin was used for DME on the CEJ and for the restoration of the MOD cavities; beforehand, tooth preparations were conducted and MZi crowns were and cemented using resin cement. The maximum load to fracture (in newtons (N)) and FR (in megapascals (MPa)) were measured using the universal testing machine. Results: The average scores indicate a gradual decrease in the load required to fracture the samples from Groups A to D, with mean values of 3415.61 N, 2494.11 N, 2108.25 N and 1891.95 N, respectively. ANOVA revealed highly significant differences between the groups. Multiple group comparisons using the Tukey HSD post hoc test revealed that Group D had greater DME depths and showed significant differences compared with Group B. Conclusions: FR in teeth decreased when more tooth structure was involved, even with MZi crowns. However, DME up to 2 mm below the CEJ did not negatively influence the FR. Strengthening the DME-treated teeth with MZi crowns could be a reasonable clinical option, as the force required to fracture the samples far exceeded the maximum recorded biting force for posterior teeth.
Forced vertical vibration of rigid discs with arbitrary embedment

This paper is concerned with the investigation of the forced time‐harmonic vertical vibration of a rigid disc embedded at an arbitrary depth in a semi‐infinite medium. By virtue of transform methods, the generalized mixed boundary‐value problem is formulated as a set of dual integral equations, which, in turn, are reduced to a Fredholm equation of the second kind. With the aid of contour integration, the governing integral equation is solved numerically. Selected results for the complex compliance are presented to illustrate the various effects of embedment on the dynamic response. In addition to furnishing a unified view of the static and dynamic solutions for zero and infinite embedments, the present analysis reveals a dynamic boundary‐layer phenomenon, which is apt to be of interest to this class of problems in general.
Intraoperative Testing During the Mapping of the Language Cortex

Intracranial lesions, particularly in the language-eloquent areas of the brain, can affect one's speaking ability. Despite advances in surgery, the excision of these lesions can be challenging. Intraoperative neurophysiological monitoring (IONM) during awake craniotomies can help identify language-eloquent areas and minimize postoperative impairments. Preoperative language testing is performed to establish a baseline before intraoperative language testing. This involves subjecting patients to predetermined tasks in the operating room to evaluate their phonological, semantic, and syntactic capabilities. The current state and future directions of intraoperative language testing procedures are discussed in this paper. The most common intraoperative tasks are counting and picture naming. However, some experts recommend utilizing more nuanced tasks that involve regions affected by infrequently occurring tumor patterns. Low-frequency bipolar Penfield stimulation is optimal for language mapping. Exception cases are discussed where awake craniotomies are not feasible. When dealing with multilingual patients, the patient's age of learning and skill level can be accounted for in terms of making informed task choices and mapping techniques to avoid any damage to language areas.
Uncovering Actions of Type 3 Deiodinase in the Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD)

Metabolic dysfunction-associated fatty liver disease (MAFLD) has gained worldwide attention as a public health problem. Nonetheless, lack of enough mechanistic knowledge restrains effective treatments. It is known that thyroid hormone triiodothyronine (T3) regulates hepatic lipid metabolism, and mitochondrial function. Liver dysfunction of type 3 deiodinase (D3) contributes to MAFLD, but its role is not fully understood. Objective: To evaluate the role of D3 in the progression of MAFLD in an animal model. Methodology: Male/adult Sprague Dawley rats (n = 20) were allocated to a control group (2.93 kcal/g) and high-fat diet group (4.3 kcal/g). Euthanasia took place on the 28th week. D3 activity and expression, Uncoupling Protein 2 (UCP2) and type 1 deiodinase (D1) expression, oxidative stress status, mitochondrial, Krebs cycle and endoplasmic reticulum homeostasis in liver tissue were measured. Results: We observed an increase in D3 activity/expression (p < 0.001) related to increased thiobarbituric acid reactive substances (TBARS) and carbonyls and diminished reduced glutathione (GSH) in the MAFLD group (p < 0.05). There was a D3-dependent decrease in UCP2 expression (p = 0.01), mitochondrial capacity, respiratory activity with increased endoplasmic reticulum stress in the MAFLD group (p < 0.001). Surprisingly, in an environment with lower T3 levels due to high D3 activity, we observed an augmented alpha-ketoglutarate dehydrogenase (KGDH) and glutamate dehydrogenase (GDH) enzymes activity (p < 0.05). Conclusion: Induced D3, triggered by changes in the REDOX state, decreases T3 availability and hepatic mitochondrial capacity. The Krebs cycle enzymes were altered as well as endoplasmic reticulum stress. Taken together, these results shed new light on the role of D3 metabolism in MAFLD.
Doxing, regulation, and privacy protection: expanding the behavioral consequences of the third-person effect

ABSTRACT This study investigates the third-person effect in relation to the internet-related practice of doxing. A national phone survey with a representative sample of adult citizens (N = 486) was conducted in Taiwan. The respondents reported that they were exposed to mediated messages about doxing through social media or news media. They tended to find others more vulnerable to the influence of media than themselves. The self-other discrepancy of perceived media influence was found to be associated with support for regulating doxing and intentions to engage in doxing. Perceived media influence on others was also found to motivate people to protect their privacy. The findings inform public opinion about doxing and expand the range of behavioral consequences that perceived media influence might induce.
Phenotypic variations among Laudakia stellio populations in Anatolia: Colour, colour pattern, and phylogeny (Reptilia: Agamidae)

We examined the phenotypical intra- and inter-populational variation of Laudakia stellio, one of the most-studied agamids, which is widely distributed in Anatolia in order to reveal the qualitative and quantitative aspects of the morphological differences among populations. We used for the quantification of colouration of different body parts colour palettes with the RGB (Red-Green-Blue) colour scale and prepared colour histograms. The populations were compared with Principal Component Analyses (PCA). We found that the 1st dorsal pattern which is the first of 4-5 star-like pattern throughout the vertebral line, provides information about the sex of the individual and the geographic location of the population. PCA graphs revealed the colouration differences between localities of dorsal, lateral, ventral head and dorsal body regions. A phylogenetic analysis of the mitochondrial ND4 marker revealed four different lineages, namely Hatay, Adana-Mersin-Konya, Burdur-Denizli and Manisa-İzmir-Çanakkale. Noting the need for new studies with different genes, our results show that colouration and quantitative morphology are supported by phylogeny in L. stellio populations, especially in terms of subspeciation.
Reaction cross sections at intermediate energies and Fermi-motion effect

Precise measurements of the reaction cross sections ($\ensuremath{\sigma}{}_{\mathrm{R}}$) for $^{12}\mathrm{C}$ on Be, C, and Al targets and $^{11}\mathrm{Be}$ on Be targets were performed in the energy range between 30 and 400 MeV/nucleon. The energy dependencies of $\ensuremath{\sigma}{}_{\mathrm{R}}$ for $^{12}\mathrm{C}$, $^{11}\mathrm{Be}$, and $^{8}\mathrm{B}$ were compared to Glauber-type calculations performed using reliable nucleon-density distributions that are supported by experimental data. It was found that the Glauber-type calculations, which include the higher-order multiple scattering effect, the finite-range effect, and the Fermi-motion effect of nucleons in the nucleus, seem to provide a good prescription relating $\ensuremath{\sigma}{}_{R}$ at intermediate energies to a proper nucleon-density distribution. This method provides a powerful tool with which to study the nuclear surface structure through the $\ensuremath{\sigma}{}_{\mathrm{R}}$ measurements.
On the inviscid stability of parallel bubbly flows

This paper investigates the effects of bubble dynamics on the stability of parallel bubbly flows of low void fraction. The equations of motion for the bubbly mixture are linearized for small perturbations and the parallel flow assumption is used to obtain a modified Rayleigh equation governing the inviscid stability problem. This is then used for the stability analysis of two-dimensional shear layers, jets and wakes. Inertial effects associated with the bubble response and energy dissipation due to the viscosity of the liquid, the heat transfer between the two phases, and the liquid compressibility are included. Numerical solutions of the eigenvalue problems for the modified Rayleigh equation are obtained by means of a multiple shooting method. Depending on the characteristic velocities of the various flows, the void fraction, and the ambient pressure, the presence of air bubbles can induce significant departures from the classical stability results for a single-phase fluid.
Thermal, magnetic, and magnetoelastic data on three different Heusler alloys based on Ni-Mn-X (X=Ga, in, or Sn)

This paper reports on a study of the influence of In and Sn substitution for Ga in Ni/sub 2/MnGa on the magnetism and magnetostriction in arc-melted-and-cast and directionally solidified alloys. Magnetostriction measurements were carried out from room temperature down to -125/spl deg/C for these alloys. Magnetic property measurements for the stoichiometric as arc-melted-and-cast rods of Ni/sub 2/MnGa, Ni/sub 2/MnSn, and Ni/sub 2/MnIn show room temperature Ms values of 58.8, 44.3, and 39.1 emu/g, respectively. Each of the stoichiometric alloys reveals similar magnetostrictive behavior with respect to temperature. For near-stoichiometric compositions, the behavior of magnetostriction in Ni-Mn-In and Ni-Mn-Sn is comparable to that in Ni-Mn-Ga in the directionally solidified samples.
H2 CONTROLLER DESIGN FOR NETWORKED CONTROL SYSTEMS

This paper deals with the problem of designing an H2 controller for a networked control system (NCS) with communication delays from the sensor to the controller and/or from the controller to the plant. Our objective is to design a robust controller that will not only stabilize the system but also achieve a sub‐opti‐ mal H2 performance in the face of possible communication delays. Both the state feedback control and output feedback control are considered. The feedback control problem for the original system is first converted to a static output feedback control problem. A recursive linear matrix inequality (LMI) algorithm is then presented to compute a state or output feedback H2 controller for the system. Our approach allows a fixed order controller. Numerical examples are given to demonstrate the effectiveness of the proposed approach.
Stock Market Prediction Model Based on LSTM Deep Learning: The Case of Top Corporate Company in China

The fluctuation of stock market price is the basis of stock market operation. The big fluctuation of stock market price will cause huge losses to investors. Stock price fluctuation is a highly complex nonlinear system, the price adjustment is not in accordance with the uniform time process, has its own process, has high risk, is very difficult to predict. The stock prediction topic is one of the most explored area of research. However, due to the characteristics of large quantity, non-linearity and long memory of stock price data, the traditional machine learning methods have some problems, such as few model parameters, impractical, time-consuming prediction and so on. Therefore, how to study effective deep learning methods to improve the recognition efficiency and prediction accuracy of forecasting models is an urgent problem to be solved in the field of stock forecasting. Based on the theory of deep learning, this paper constructs a stock price prediction index system according to the characteristics of China’s top enterprises. In this paper, the stock price trend of Build Your Dreams (BYD), the top new energy vehicle company in China, is taken as the main data set, and the Long and Short-term Memory (LSTM) recurrent neural network is used to predict BYD’s stock price. This paper solves the long sequence dependence problem in general recursive neural networks. Using the characteristics of recurrent neural network and stock market, the data are preprocessed by interpolation and wavelet denoising, and then pushed to different LSTM layers. Training and testing were carried out in LSTM network models with different numbers of hidden neurons at the same level. The evaluation indexes and prediction effects were compared to find the appropriate LSTM layers and hidden neurons to improve the prediction accuracy
Classical Cepheids and Galactic Structure

In this review I consider recent results on the space distribution of classical Cepheids, first dealing with their Z-distribution normal to the galactic plane, and second considering their X,Y components in the plane. In doing so, use is made of a new database of 505 stars known to be or likely to be classical Cepheids which has recently been compiled by Fernie et al. (1995) and which is available electronically on the World Wide Web at the URL http://ddo.astro. utoronto.ca/cepheids.html , and by anonymous ftp at perseus.astro. utoronto.ca (128.100.77.18) in the directory pub/cepheids. Following the discussion of space distribution, a review of recent work on Cepheid kinematics and the resulting determination of the distance to the galactic centre will be given.
Simulations of bypass transition

Bypass transition in an initially laminar boundary layer beneath free-stream turbulence is simulated numerically. New perspectives on this phenomenon are obtained from the numerical flow fields. Transition precursors consist of long backward jets contained in the fluctuating u-velocity field; they flow backwards relative to the local mean velocity. The jets extend into the upper portion of the boundary layer, where they interact with free-stream eddies. In some locations a free-stream perturbation to the jet shear layer develops into a patch of irregular motion – a sort of turbulent spot. The spot spreads longitudinally and laterally, and ultimately merges into the downstream turbulent boundary layer. Merging spots maintain the upstream edge of the turbulent region. The jets, themselves, are produced by low-frequency components of the free-stream turbulence that penetrate into the laminar boundary layer. Backward jets are a component of laminar region streaks. A method to construct turbulent inflow from Orr–Sommerfeld continuous modes is described. The free-stream turbulent intensity was chosen to correspond with the experiment by Roach & Brierly (1990). Ensemble-averaged numerical data are shown to be in good agreement with laboratory measurements.
Nonlinear optical response and heating of chalcogenide glasses upon irradiation by the ultrashort laser pulses

Abstract. Large third-order nonlinearity and transparency in the mid-infrared region are the basic motivations for prospective applications of chalcogenide glasses in nonlinear photonics and laser technologies. We present the state-of-the-art and our recent results of measurement and evaluation of the nonlinear optical constants, plasma dynamics, and thermal regimes upon irradiation of As-S-Se samples using 40-fs pulses at 790-nm wavelength.
Does Intrauterine Exposure of the Foetus to Immunosuppressive Drugs Used by the Mother—The Organ Recipient—Affect the Development of Post-Vaccination Immunity against Selected Viral Diseases in Children of These Mothers in Postnatal Life?

Background: Pregnancy in women who are organ recipients has long been a controversial issue due to the lack of data on the safety of immunosuppressive drugs for the developing foetus. Scientific data show that the effect of immunosuppressants on the foetus causes an impairment of T and B lymphocyte function and a reduction in their total number. For this reason, some authors recommend delaying the obligatory immunization of infants. The aim of the study is to analyse the impact of chronic immunosuppressive therapy used during pregnancy by women after organ transplantation on the effectiveness of anti-viral vaccinations in the children of these women. Methods: Concentrations of post-vaccination IgG antibodies (measles, HBV, polio) in 18 children of post-transplant mothers (9KTRs; 9LTRs) were determined using the ELISA method. The results were compared with the control group (n = 21). The incidence of vaccination AEs was also analysed. Results: There were no significant differences between the analysed groups in the concentrations of antibodies against HBV, measles and polio (p > 0.05). Conclusions: No difference was observed in the immunogenicity of HBV, polio and measles vaccinations between children of post-transplant mothers and the general population. The immunization of children of post-transplant mothers is safe, and the percentage of adverse post-vaccination events does not differ from the general population. The obtained study results do not indicate the necessity for modifying the vaccination program for HBV, measles, and polio in this group of patients.
A Finite Model Construction For Coalgebraic Modal Logic

In recent years, a tight connection has emerged between modal logic on the one hand and coalgebras, understood as generic transition systems, on the other hand. Here, we prove that (nitary) coalgebraic modal logic has the nite model property. This fact not only reproves known completeness results for coalgebraic modal logic, which we push further by establishing that every coalgebraic modal logic admits a complete axiomatisation in rank 1; it also enables us to establish a generic decidability result and a rst complexity bound. Examples covered by these general results include, besides standard Hennessy-Milner logic, graded modal logic and probabilistic modal logic.
