Secure Palmprint Recognition based on Multispectral Sequential Capture

—The security of personal identities is a serious challenge in today's digital world, with so many daily transactions requiring secure solutions. The use of biometric characteristics of the person is presented as the reliable solution to solve this problem. Indeed, this solution is effective, but it hides a weak point which lies in the ability to reproduce certain biometric characteristics for fraud. To overcome this weak point, we propose a secure approach for palmprints that relies on the concept of merging multiple features. Indeed, these features will be extracted from multi-spectral images with different spectra, which allow the extraction of information under the skin of the palm for two different spectrums sequentially in two different times (T1, T2) but instantly. The instant fusion of these characteristics will be impossible to replicate. The images used are grayscale. To satisfy a construction of a reliable and secure system, for this kind of patterns (palmprints), we will use the Compound Local Binary Pattern method, since this method adds an additional bit for each P bits coded by LBP corresponding to a neighbor of the local neighborhood, in order to build a robust system. This feature descriptor, it uses both the sign and tilt information of the differences between the central and neighboring gray values. The reliability of the proposed approach has been demonstrated on the Casia Multi-Spectral database. The final experimental results show reliable recognition rates and these recognition rates vary between 99% and 100% for the left and right palms.
Efektifitas Filtrat Kultur yang Dihasilkan Oleh Berbagai Ras Sclerotium Rolfsii Terhadap Pertumbuhan in Vitro Kecambah Kacang Tanah

The objective of this research was to evaluate of culture filtrate effectiveness produced by S. rolfsii races against in vitro growth of peanut seedling. The experiment was inisiated with characterize and hyphal anastomosis group test of S. rolfsii isolates. This experiment has been gotten 4 races (race 1, 8, 6, 9). Four races were proliferated for used as culture filtrate selective agents. This culture filtrate will be used as material to be added with MS medium to peanut seedling growth test. Culture filtrate MS medium (MS+CF) consisted of MS based medium, B5 vitamin, sucrose (30 g/L), agar, and culture filtrate (different concentration 0, 25, 30, 35%). Seeds of peanut (cv. Local Bima, Kelinci, G-250, G-300) were cultivated in different concentration of culture filtrate of MS+CF medium. Results of study showed that culture filtrate from different races affected significantly againts seed germination ability and inhibited growing peanut seedling. Culture filtrate concentration 35% was more inhibited to peanut seedling growing compared with lower culture filtrate concentration or compared control (without culture filtrate).
Impact of Silicon and Endophytic Fungi Application for Plant Survival, Biomass and Chemical Compositions of Moringa oleifera Lam. Under Salinity Stress Conditions

The newly reclaimed soils suffer from some stresses, especially salinity, whether in the soil or irrigation water that severely hinder the growth and production of some crops. A pot experiment was conducted during 2021 and 2022 seasons at Al-Marashda Research Station, Qena, ARC, Egypt to study the influence of silicon and endophytic fungi on germination percentage, survival seedlings rate, biomass and chemical traits of Moringa oleifera under salinity conditions. Pots were filled with sandy soil as substrate and arranged in completely randomized design, having nine treatments, including silicon and endophytic fungi together or alone with two levels of salinity. The two salinity levels were significantly affected the germination and survival percentages, biomass as well as chemical compositions of M. oleifera . However, addition of silicon at 100 mg/ l or endophytic fungus ( Chaetomium globosum ) at 100 ml, together or alone led to increase germination percentage and survival rate, biomass characters, N, P, K, and total chlorophyll in moringa leaves under saline conditions. The improvement was better with lower salinity level (3 dS m -1 ) compared to the higher one for the 1 st and 2 nd seasons. Application of both silicon and endophytic fungi led to better growth results compared to the individual treatments. Leaves of salt- treated plants without any additives contained high levels of Na + and Cl - compared to those treated with saline reducers.
Critical behavior and magnetic-entropy change of orthorhombic La0.7Ca0.2Sr0.1MnO3

We prepared a polycrystalline sample of orthorhombic La0.7Ca0. 2Sr0.1MnO3 and then investigated its magnetic properties. Detailed studies and analyses in the vicinity of the ferromagnetic (FM)-paramagnetic phase-transition temperature prove the sample undergoing a second-order phase transition, where variations of the saturation magnetization and the initial susceptibility versus temperature obey asymptotic relations. Basing on the modified Arrott plot, we have determined the critical parameters (TC, β, γ, and δ) in the two characteristic regions of low- and high-magnetic fields, and in the cases of no-subtracting and subtracting the demagnetization field (Hd). The experimental results reveal that values of the critical parameters depend remarkably on analysis routes of isothermal-magnetization data. Intrinsically, β keeps close to the value expected for the 3D Heisenberg ferromagnets with ferromagnetic short-range interactions, while γ is close to the value of the mean-field theory. These results are diff.
Receptor-Mediated Modulation of Murine Mast Cell Function by α-Melanocyte Stimulating Hormone

The proopiomelanocortin (POMC)-derived neuropeptide α-melanocyte stimulating hormone (α-MSH) is known to modulate some aspects of inflammation through direct effects on T cells, B cells, and monocytes. To determine whether α-MSH might similarly influence mast cell responsiveness, mast cells were examined to see if they expressed the receptor for α-MSH, melanocortin-1 (MC-1), and whether α-MSH altered mast cell function. We thus first identified MC-1 on bone marrow cultured murine mast cells (BMCMC) and a murine mast cell line (MCP-5) employing flow cytometry and through detection of specific binding. Subsequent treatment of mast cells with α-MSH increased the cAMP concentration in a characteristic biphasic pattern, demonstrating that α-MSH could affect intracellular processes. We next examined the effect of α-MSH on mediator release and cytokine expression. IgE/DNP-human serum albumin-stimulated histamine release from mast cells was inhibited by ∼60% in the presence of α-MSH. Although activation of BMCMC induced the expression of mRNAs for the inflammatory cytokines IL-1β, IL-4, IL-6, TNF-α, and the chemokine lymphotactin, mRNAs for IL-1β, TNF-α, and lymphotactin were down-modulated in the presence of α-MSH. Finally, IL-3-dependent proliferative activity of BMCMC was slightly but significantly augmented by α-MSH. Taken together, these observations suggest that α-MSH may exert an inhibitory effect on the mast cell-dependent component of a specific inflammatory response.
Silicon microgyroscope temperature prediction and control system based on BP neural network and Fuzzy-PID control method

We present a novel silicon microgyroscope (SMG) temperature prediction and control system in a narrow space. As the temperature of SMG is closely related to its drive mode frequency and driving voltage, a temperature prediction model can be established based on the BP neural network. The simulation results demonstrate that the established temperature prediction model can estimate the temperature in the range of −40 to 60 °C with an error of less than ±0.05 °C. Then, a temperature control system based on the combination of fuzzy logic controller and the increment PID control method is proposed. The simulation results prove that the Fuzzy-PID controller has a smaller steady state error, less rise time and better robustness than the PID controller. This is validated by experimental results that show the Fuzzy-PID control method can achieve high precision in keeping the SMG temperature stable at 55 °C with an error of less than 0.2 °C. The scale factor can be stabilized at 8.7 mV/°/s with a temperature coefficient of 33 ppm °C−1. ZRO (zero rate output) instability is decreased from 1.10°/s (9.5 mV) to 0.08°/s (0.7 mV) when the temperature control system is implemented over an ambient temperature range of −40 to 60 °C.
The Coronal Properties of the High-Metallicity Late-G Dwarf 11 LMi

The influence of stellar metallicity on stellar coronal properties is still unclear, since most of the stars with well‐studied coronal spectra have photospheric abundances similar to (or assumed to be) the solar photospheric values. We have used XMM‐Newton to observe 11 LMi, a known X‐ray source, which has supersolar (2.0–2.5 times solar) photospheric abundances, in order to study the effect of the high underlying intrinsic metallicity on the temperature structure and abundances of its coronal plasma. We present and discuss the EPIC spectra of 11 LMi that we have obtained, and compare the properties of its coronal emission with those of similar stars of solar metallicity.
Stability in Cohen–Grossberg-type bidirectional associative memory neural networks with time-varying delays

In this paper, the exponential stability problem is investigated for a class of Cohen–Grossberg-type bidirectional associative memory neural networks with time-varying delays. By using the analysis method, inequality technique and the properties of an M-matrix, several novel sufficient conditions ensuring the existence, uniqueness and global exponential stability of the equilibrium point are derived. Moreover, the exponential convergence rate is estimated. The obtained results are less restrictive than those given in the earlier literature, and the boundedness and differentiability of the activation functions and differentiability of the time-varying delays are removed. Two examples with their simulations are given to show the effectiveness of the obtained results.

Thirdly, the compressing image is used to restoration the original image. Experimental results show that the proposed algorithm is effective and compares favorably with existing techniques.
Electron kinetic energy measurements from laser irradiation of clusters

We have measured electron kinetic energy spectra from the interaction of a low-density beam of noble-gas clusters with a high-intensity femtosecond laser pulse. Electron energies were measured both through their time of flight and through measurements of electron signals as a function of retarding voltages up to 7 kV. We have observed electrons with energies up to 6 keV and a sharp peak at an arrival time consistent with the detection of photons. The electrons had a broad angular distribution peaked along the polarization axis, while the sharp peak had an isotropic angular distribution. We attribute this sharp peak to uv, xuv, or x-ray photons formed as a result of the laser-cluster interaction and were unable to observe the two-lobed electron kinetic energy distribution reported by Shao et al. [Phys. Rev. Lett. 77, 3343 (1996)] with any combination of the laser and cluster parameters used.
Advances in Electrochemical Biosensors Based on Nanomaterials for Protein Biomarker Detection in Saliva

The focus on precise medicine enhances the need for timely diagnosis and frequent monitoring of chronic diseases. Moreover, the recent pandemic of severe acute respiratory syndrome coronavirus 2 poses a great demand for rapid detection and surveillance of viral infections. The detection of protein biomarkers and antigens in the saliva allows rapid identification of diseases or disease changes in scenarios where and when the test response at the point of care is mandated. While traditional methods of protein testing fail to provide the desired fast results, electrochemical biosensors based on nanomaterials hold perfect characteristics for the detection of biomarkers in point‐of‐care settings. The recent advances in electrochemical sensors for salivary protein detection are critically reviewed in this work, with emphasis on the role of nanomaterials to boost the biosensor analytical performance and increase the reliability of the test in human saliva samples. Furthermore, this work identifies the critical factors for further modernization of the nanomaterial‐based electrochemical sensors, envisaging the development and implementation of next‐generation sample‐in‐answer‐out systems.
Meyer–Neldel rule for liquid semiconductors

The fact that the Meyer–Neldel rule is obeyed in many liquid semiconductors has led to the examination of its origin. An explanation based on a statistical shift of the Fermi energy with temperature is shown to be unrealistic. Multiphonon hopping is suggested as an explanation of the temperature and composition dependence of the electrical conductivity. This mechanism has the advantage of being universally valid for amorphous, crystalline, and liquid semiconductors.

Bisphenol A in Children with Bronchial Asthma and Its Relation to Body Mass Index

Background: One of the most debilitating diseases in children is bronchial asthma. Little research has been conducted into the relationship between bisphenol A (BPA), a commonly recycled monomer, which is linked to childhood obesity and asthma. Objective: This study's aimed to examine the relationships between paediatric obesity morbidity and bisphenol A (BPA). Subjects and Methods: 100 kids between 4 and 10 years were included in this study (25 asthmatics, 25 asthmatics with obesity, 25 obese non-asthmatics, and 25 healthy controls). The diagnosis of asthmatic children was made according to GINA guidelines (Global Initiative for Asthma). The BPA competitive ELISA Kit was used to measure the BPA levels in urine specimens. Looked up for the effect of BPA as a predictor of asthma development in asthmatic children. Additionally, research was done on BPA's potential role in the prediction of childhood obesity. Results: High median total urinary BPA levels (p > 0.001) detected significantly in children with asthma and obesity. Increased levels of BPA were found to be a significant predictor (p = 0.006) in an analysis using multiple logistic regression of asthma predictors. Conclusions: It's possible that BPA played a role in the development of bronchial asthma & obesity, based on the correlation between high BPA levels in urine with asthma diagnostic assessments and children obesity. There is a need for more clinical and biochemical study .
The influence of misrepresenting the nocturnal boundary layer on idealized daytime convection in large‐eddy simulation

The influence of poorly resolving mixing processes in the nocturnal boundary layer (NBL) on the development of the convective boundary layer the following day is studied using large‐eddy simulation (LES). Guided by measurement data from meteorological sites in Cabauw (Netherlands) and Hamburg (Germany), the typical summertime NBL conditions for Western Europe are characterized, and used to design idealized (absence of moisture and large‐scale forcings) numerical experiments of the diel cycle. Using the UCLA‐LES code with a traditional Smagorinsky‐Lilly subgrid model and a simplified land‐surface scheme, a sensitivity study to grid spacing is performed. At horizontal grid spacings ranging from 3.125 m in which we are capable of resolving most turbulence in the cases of interest to grid a spacing of 100 m which is clearly insufficient to resolve the NBL, the ability of LES to represent the NBL and the influence of NBL biases on the subsequent daytime development of the convective boundary layer are examined. Although the low‐resolution experiments produce substantial biases in the NBL, the influence on daytime convection is shown to be small, with biases in the afternoon boundary layer depth and temperature of approximately 100 m and 0.5 K, which partially cancel each other in terms of the mixed‐layer top relative humidity.
RESONANT MODES OF STACKED CIRCULAR MICROSTRIP PATCHES IN MULTILAYERED SUBSTRATES CONTAINING ANISOTROPIC AND CHIRAL MATERIALS

Galerkin's method in the Hankel transform domain (HTD) is applied to the fast and accurate determination of the resonant frequencies, quality factors and radiation patterns of stacked circular microstrip patches. The stacked metallic patches are assumed to be embedded in a multilayered substrate which may contain isotropic dielectrics, uniaxial anisotropic dielectrics, magnetized ferrites and/or chiral materials. For the case of stacked microstrip patches fabricated on isotropic dielectrics, the numerical results obtained for the resonant frequencies are compared with measurements carried out by the authors and with numerical results computed by means of the electromagnetic simulator "Ensemble". Good agreement is found among all sets of results. Original results are presented for the resonant frequencies of patches fabricated on anisotropic dielectrics and chiral materials, which show that substrate dielectric anisotropy and substrate chirality are not negligible effects. Finally, the results obtained for patches fabricated on magnetized ferrites indicate that the resonant frequencies of these patches can be adjusted over a wide range by means of the bias magnetic field, and that resonances cannot occur in the frequency region where magnetostatic mode propagation is allowed.
Molecular Identification of Ladybird Beetles (Coccinella: Coccinellidae) Using DNA Barcodes

DNA barcoding is a molecular genetics technique commonly applied for species identification based on the cytochrome c oxidase subunit I (COI) gene located on the mitochondrial DNA genome. Based on our analysis, the DNA barcodes were generated from 16 specimen of Coccinella (family Coccinellidae). All the samples were collected from diverse sites in Egypt and Libya. Morphological traits based on the number of dorsal spots, DNA extraction, PCR amplification of COI, sequencing, nucleotide BLAST, and phylogenetics analyses were used to classify the specimens. A phylogenetic tree was constructed using the maximum likelihood method, including 46 COI sequences (the study and NCBI sequences). Three Coccinella clusters were defined and classified as Coccinella septempunctata, Coccinella novemnotata, and Coccinella undecimpunctata each species clustered into a unique branch. DNA barcodes discriminated clearly against the analyzed species. This study validated the COI efficiency as a marker for DNA barcoding of insects (Coccinella, family Coccinellidae).
Pulsational Study of BL Herculis Models. I. Radial Velocities

The linear and nonlinear pulsational behavior of nine sequences of BL Herculis models is studied, and their radial velocity curves are discussed in detail. The pulsations of these stars, in analogy to the classical Cepheids, are strongly affected by internal resonances, most importantly the 2:1 resonance with the second overtone. This latter coupling causes a characteristic systematic progression of the Fourier phases and amplitude ratios as the period ratio P 2 /P 0 is varied
Equivalent Circuit for Antenna-Cavity Coupling in Wheeler's Cap Technique

An equivalent circuit is derived for an antenna coupled to a shielding cavity via field analysis. The input impedance of the antenna inside the cavity is then studied theoretically and experimentally. It is shown that the input resistance of the antenna shielded by the cavity is not merely the loss resistance, but is actually the sum of the antenna loss resistance and the coupling resistance between the antenna and cavity. This coupling effect is demonstrated quantitatively by numerical computations for dipole antennas. A method is proposed to avoid the antenna-cavity antiresonance in the measurement of loss resistance of the antenna.
RBM4 inhibits the growth of clear cell renal cell carcinoma by enhancing the stability of p53 mRNA

RBM4 has been reported as a tumor suppressor gene in cancers, including lung cancer, colon cancer and gastric cancer. However, the role of RBM4 in clear cell renal cell carcinoma (ccRCC) remains unclear. Therefore, the present study investigated the expression and biological function of RBM4 in ccRCC. Analysis of the differential expression of RBM4 and its relationship with clinicopathological features using ccRCC samples data from TCGA database deminstrated that RBM4 expression in tumor samples of ccRCC was lower than that in normal samples, and RBM4 expression was closely related to the survival time of patients. RBM4 overexpression (RBM4‐oe) cell lines were constructed to investigate the effect of RBM4 on biological function using CCK‐8, EdU, flow cytometry and wound‐healing assays. In addition, the regulatory effect of RBM4 on signaling pathways was investigated by GSEA and WB assays. RBM4‐oe significantly reduced the proliferation of ccRCC cells by controlling the p53 signaling pathway, inhibited cell cycle progression and promoted apoptosis. In addition, RBM4‐oe suppressed the migration and invasion of cells by EMT. Mechanistically, RBM4‐oe facilitated the activity of the p53 signaling pathway by enhancing the stability of p53 mRNA. Finally, RBM4‐oe markedly inhibited the growth of tumors formed with 786‐O cells in vivo. In summary, there findings suggeated that RBM4 inhibits the progression of ccRCC by promoting p53 signaling pathway activity by enhancing the stability of p53 mRNA, suggesting that RBM4 may be a potential target for the treatment of patients.
Existence of edge waves along three-dimensional periodic structures

Existence of edge waves travelling along three-dimensional periodic structures is considered within the linear water-wave theory. A condition ensuring the existence is derived by analysing the spectrum of a suitably defined trace operator. The sufficient condition is a simple inequality comparing a weighted volume integral, taken over the submerged part of an element in the infinite array of identical obstacles, to the area of the free surface pierced by the obstacle. Various examples are given, and the results are extended to edge waves along periodic coastlines and over a periodically varying ocean floor.
A linear programming approach to on‐line constrained optimal terrain‐tracking systems

The idea of an optimal decision strategy is applied to a class of tracking problems. The resulting pointwise optimization problem is posed as a linear programming problem, in contrast to previous work where it is posed as a quadratic programming problem. A useful result concerning the convergence of the tracking error in the presence of control constraints is derived and applied to an aircraft terrain-following system.
