Rhizospheric actinobacteria of Opuntia sp. “prickly pear” with deaminase activity as growth promoting in Solanum lycopersicum L. under salinity stress

The growing of Solanum lycopersicum L. "tomato" is affected by salinity, reducing its water consumption, and affecting negatively plant growth and development. Therefore, it is necessary to seek sustainable cultivation and fertilization options, such as the use of plant growth-promoting rhizobacteria. This research aimed to determine the potential of rhizospheric Actinobacteria isolated from Opuntia sp. "prickly pear" as tomato growth promoting under salinity. The genera of isolated Actinobacteria were identified, the synthesis of 1-aminocyclopropane-1-carboxylic acid deaminase (ACC) was characterized and its effect on the germination of tomato cultivar Río Grande seeds was evaluated. Two tests on non-saline and saline soils were carried out to compare the effect of Streptomyces spp. and Nocardia sp. in plant development in the greenhouse. Several Actinobacteria genera were isolated from 87.03% of samples, highlighting Streptomyces (46.67%) and Nocardia (34.0%). 9.33% of the Actinobacteria presented ACC deaminase activity, which increased seed germination, and the growth and yield of seedlings with increases of 88.98% (height); 96.30% (number of sheets); 201.35% (aerial biomass); 173.77% (root length); 100.0% (root weight); 150.0% (number of fruits) and 173.14% (weight of fruits), as well as 1.37 mg/g in the chlorophyll content in the saline soil. Also, Streptomyces sp. strain 21 decreased sodium content and increased potassium and K+/Na+ rate in the leaves and roots of the plants with the highest yield (1.068 kg/plant) in the saline soil. In conclusion, the positive effect of Actinobacteria as promoters of tomato growth and yield, increasing chlorophyll content, and decreasing salinity stress was demonstrated.
Disentangled Representation and Enhancement Network for Vein Recognition

Recently, vein recognition has been paid more considerable attention in biometric recognition fields. In the process of vein image acquisition, due to the influence of external factors such as illumination change, the texture information of vein images with the same identity information may change, which enhances the difference of intra-class and extremely degrades the performance of vein recognition systems. To address this problem, we proposed a Disentangled Representation and Enhancement Network for vein recognition called DRE-Net. First, robust vein shape masks are obtained by the designed vein segmentation algorithms, which are utilized as label information in DRE-Net to acquire the shape features of vein images. Second, a disentangled representation network which contains two encoders and two decoders is designed to disentangle the texture features and shape features of vein images. Besides, a Multi-Scale Attention Residual Block (MSARB) is presented to better mine the vein network information and enhance the representation ability of DRE-Net for vein images. Finally, a Weight-Guided Feature Enhancement Module (WGFEM) is presented to obtain more discriminative representations for vein recognition by reducing the importance of texture features and increasing the importance of shape features, which decreases the difference of intra-class caused by illumination change. Extensive experiments have been carried out on three benchmark vein databases, and the experimental results demonstrate that our proposed model outperforms the state-of-the-art methods.
Design and Construction of Duku Sorting System Based on Size Using a Microcontroller on Conveyor Work

Duku (Lansuim Domesticum Corr)fruit harvesting is generally done manually by farmers in Indonesia so that the quality of the duku fruit, especially the uniformity of size, is not considered. The impact of this harvesting is a decrease in fruit quality and a decrease in selling prices. It is necessary to develop a new sorting machine for duku so that the fruit size is accurate. This research aims to make a sorting system for duku fruit based on size using a microcontroller on conveyor work. The sorting system uses two sensors, VL53L0X and FC-51. The design has a servo actuator to separate the fruit classes. This study developed a correct sorting of duku fruit sizes up to 97.4%, counting accuracy up to 99.4%, system stability up to 96.65%, and transient response of 100 ms. The result of testing this tool is that the ability of the Duku fruit sorting system based on size has a stability value of 96.6%. The transient response obtained is 100ms. The accuracy of the perfect sorting results is 97.4%, and the calculation of the number of duku using the system is 99.4%. The conclusion is that the researchers can create a sorting system based on size using a microcontroller on conveyor work.
Minimax LCAO approach to the relativistic two-centre Coulomb problem and its finite element (FEM) spectrum

The one-electron relativistic diatomic systems H + and Th 179+ are solved in a two-spinor linear combination of atomic orbitals (LCAO) approach using a minimax principle equivalent to a constraint minimization. The values are in agreement with those of the finite element method (FEM) and of other approaches as far as results are available in the literature. No spurious or contaminated states are found. The complete spectrum for Th 179+ up to n = 6 correlating s1/2 to h11/2 states is given.
Molecular-beam epitaxial growth of GaAs and InGaAs/GaAs nanodot arrays using anodic Al2O3 nanohole array template masks

Highly ordered arrays of nanosized GaAs-based dots were successfully prepared on GaAs (001) substrates by molecular-beam epitaxy using selected area growth. Selected area growth employed alumina nanochannel array (NCA) templates formed by anodic oxidation, bonded to the GaAs substrates. Homogeneous GaAs dots, as well as compositionally modulated heterostructures within the nanosized dots, were demonstrated. In the latter case, multilayer InGaAs/GaAs heterostructured nanodot arrays were fabricated. Dot growth occurred only as defined by the template mask, resulting in a hexagonal lattice of dots with 100 nm period spacing, with dots retaining the circular lateral shape of the pores as determined by the NCA template pore size; dot diameters were adjustable from 45 to 85 nm for a lattice period of 100 nm. Cathodoluminescence spectra from an InGaAs/GaAs 10×10 dot array clearly showed an emission peak at 920 nm (5 K), confirming the formation of a high-quality InGaAs/GaAs quantum dot array.
A posteriori error estimates for nonlinear problems: finite element discretizations of elliptic equations

We give a general framework for deriving a posteriori error estimates for approximate solutions of nonlinear problems. In a first step it is proven that the error of the approximate solution can be bounded from above and from below by an appropriate norm of its residual. In a second step this norm of the residual is bounded from above and from below by a similar norm of a suitable finite-dimensional approximation of the residual. This quantity can easily be evaluated, and for many practical applications sharp explicit upper and lower bounds are readily obtained. The general results are then applied to finite element discretizations of scalar quasi-linear elliptic partial differential equations of 2nd order, the eigenvalue problem for scalar linear elliptic operators of 2nd order, and the stationary incompressible Navier-Stokes equations. They immediately yield a posteriori error estimates, which can easily be computed from the given data of the problem and the computed numerical solution and which give global upper and local lower bounds on the error of the numerical solution.
Low Sound Velocities in High‐Porosity Sediments

Recent in situ and laboratory determinations of density and velocity of sound in fine‐grained, high‐porosity sediments of the sea floor off San Diego, California, reveal several stations at which the velocity of sound in the sediment was 2% to 3% less than the velocity of sound in the water just above the bottom. Comparison of the compressibility of the sediment computed in two ways and of the ratio: velocity in sediment/velocity in water computed and actually measured indicates that these high porosity sediments are approximately described acoustically by the velocity formula which applies to a suspension. The theoretical explanation for this phenomena was apparently made by R. J. Urick, [J. Appl. Phys. 18, 983 (1947); J. Acoust. Soc. Am. 20, 283 (1948)] and R. J. Urick and W. S. Ament [J. Acoust. Soc. Am. 21, 115 (1949)].
Spectral features of the body fluids of patients with benign and malignant prostate tumours

In this study, we present the results of fluorescence spectra of blood and urine to detect and discriminate between samples drawn from benign and malignant prostate patients and we find a very good demarcation in terms of spectral features. This preliminary study was carried out as a proof of concept, with limited samples of blood and urine from known cases of patients of BPH and CaP. In the near future it is expected that a detailed clinical validation will be done to establish it as a reliable cancer diagnosis protocol.
Transcriptional Insights of Oxidative Stress and Extracellular Traps in Lung Tissues of Fatal COVID-19 Cases

Neutrophil extracellular traps (NETs) and oxidative stress are considered to be beneficial in the innate immune defense against pathogens. However, defective clearance of NETs in the lung of acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients could lead to severe respiratory syndrome infection, the so-called coronavirus disease 2019 (COVID-19). To elucidate the pathways that are related to NETs within the pathophysiology of COVID-19, we utilized RNA sequencing (RNA-seq) as well as immunofluorescence and immunohistochemistry methods. RNA-seq analysis provided evidence for increased oxidative stress and the activation of viral-related signaling pathways in post-mortem lungs of COVID-19 patients compared to control donors. Moreover, an excess of neutrophil infiltration and NET formation were detected in the patients’ lungs, where the extracellular DNA was oxidized and co-localized with neutrophil granule protein myeloperoxidase (MPO). Interestingly, staining of the lipid peroxidation marker 4-hydroxynonenal (4-HNE) depicted high colocalization with NETs and was correlated with the neutrophil infiltration of the lung tissues, suggesting that it could serve as a suitable marker for the identification of NETs and the severity of the disease. Moreover, local inhalation therapy to reduce the excess lipid oxidation and NETs in the lungs of severely infected patients might be useful to ameliorate their clinical conditions.
Short-term recovery after NovaSure® endometrial ablation: a prospective cohort study

Background Endometrial ablation is a frequently performed treatment for heavy menstrual bleeding, but detailed information about recovery to help inform patients is lacking. Objective To gain more insight into the short-term recovery after NovaSure® endometrial ablation, with the goal of improving preprocedural counselling. Materials and Methods A total of 61 women who underwent endometrial ablation between March 2019 and November 2021 in a teaching hospital in the Netherlands were included in this prospective cohort study. Main outcome measures Short-term recovery was investigated through questionnaires in the first week after the procedure. The primary outcome was the Recovery Index (RI-10). Secondary outcomes included health-related quality of life (EQ-5D-5L), pain intensity, use of analgesics, nausea, vaginal discharge, capability of performing activities (domestic chores, sports, work), self-rated health (EQ-VAS) and the feeling of full recovery. Results A total of 33 women underwent the procedure under local anaesthesia and 28 women under procedural sedation. The RI-10 increased in the first week; median scores on day one, two and seven were 34 (IQR 28.5-41.5), 38.5 (IQR 31-47), and 42 (IQR 37.5-48), respectively. The median time for full recovery was five days. However, 23% of all women were not fully recovered within seven days. Women needed a median time of two days for returning to their work and 5.5 days for sporting activities. There were no differences in recovery between both anaesthesia techniques. Conclusions Women undergoing endometrial ablation can be informed that most will fully recover within the first week of the procedure and that there is no difference in expected recovery time according to whether the procedure is undertaken with local anaesthesia or conscious sedation. What is new? The short-term recovery after endometrial ablation has been mapped in this trial. This information can be used in counselling women with heavy menstrual bleeding.
Intracranial Myeloid Sarcoma Mimicking Hypertensive Intracerebral Hemorrhage

We herein report a case of intracranial myeloid sarcoma mimicking hypertensive intracerebral hemorrhage. A 71-year-old man with a history of acute myeloid leukemia was admitted with acute-onset dysarthria. A hematoma-like lesion was found on computed tomography in the left putamen. Magnetic resonance imaging (MRI) and cerebrospinal fluid cytology confirmed the diagnosis of intracranial myeloid sarcoma. The patient showed a favorable response to chemotherapy, and follow-up MRI revealed shrinkage of the tumor. Since the computed tomography findings resemble those of intracerebral hemorrhage, it is important to suspect intracranial neoplasm, particularly in cases with a history of hematologic diseases.
Trapping and Absorbing Set Enumerators for Nonbinary Protograph-Based Low-Density Parity-Check Code Ensembles

The finite-length trapping and (elementary) absorbing set enumerators for nonbinary protograph-based LDPC code ensembles are derived. Both constrained and unconstrained edge labeling approaches are considered. The normalized logarithmic asymptotic distributions of trapping and (elementary) absorbing sets are obtained through an efficient method that requires solving a system of equations. Using these results, the asymptotic distributions of trapping and (elementary) absorbing sets are evaluated for some example nonbinary protograph-based LDPC code ensembles.
Improved Antitumor Effect of NK Cells Activated by Neutrophils in a Bone Marrow Transplant Model

The licensing process mediated by inhibitory receptors of the Ly49 C-type lectin superfamily that recognizes self-major histocompatibility complex (MHC) class I in mice is essential for the proper antitumor function of natural killer (NK) cells. Several models for NK cell licensing can be exploited for adoptive immunotherapy for cancer. However, the appropriate adoptive transfer setting to induce efficient graft versus tumor/leukemia effects remains elusive, especially after hematopoietic stem cell transplantation (HSCT). In our previous experiment, we showed that intraperitoneal neutrophil administration with their corresponding NK receptor ligand-activated NK cells using congenic mice without HSCT. In this experiment, we demonstrate enhanced antitumor effects of licensed NK cells induced by weekly intraperitoneal injections of irradiated neutrophil-enriched peripheral blood mononuclear cells (PBMNCs) in recipient mice bearing lymphoma. Bone marrow transplantation was performed using BALB/c mice (H-2d) as the recipient and B10 mice (H-2b) as the donor. The tumor was A20, a BALB/c-derived lymphoma cell line, which was injected subcutaneously into the recipient at the same time as the HSCT. Acute graft versus host disease was not exacerbated in this murine MHC class I mismatched HSCT setting. The intraperitoneal injection of PBMNCs activated a transient licensing of NK subsets expressed Ly49G2, its corresponding NK receptor ligand to H-2d, and reduced A20 tumor growth in the recipient after HSCT. Pathological examination revealed that increased donor-oriented NK1.1+NK cells migrated into the recipient tumors, depending on neutrophil counts in the administered PBMNCs. Collectively, our data reveal a pivotal role of neutrophils in promoting NK cell effector functions and adoptive immunotherapy for cancer.
Large deviations for discrete and continuous percolation

Motivated by a statistical application, we consider continuum percolation in two or more dimensions, restricted to a large finite box, when above the critical point. We derive surface order large deviation estimates for the volume of the largest cluster and for its intersection with the boundary of the box. We also give some natural extensions to known, analogous results on lattice percolation.
Metal Thickness Measurement System Based on a Double-Coil Eddy-Current Method With Characteristic Ratio Detection

Eddy-current sensor systems have been employed to determine the real-time thickness distribution of metal films and the thickness at endpoint detection in metal chemical mechanical polishing (CMP) processes, to achieve global planarization and avoid overpolishing or underpolishing. However, the large lift-off distance of 3.5 mm between the sensor coil and metal film gradually decreases with continuous wear of the polishing pad, which has a strong negative impact on the sensitivity and accuracy of the thickness measurement. In this study, a double-coil eddy-current sensor system, with novel characteristic ratio detection capability, is proposed for metal film thickness measurement and compared with a traditional amplitude-based method. The linear relationship between the characteristic ratio and metal film thickness that is immune to lift-off distance is demonstrated both theoretically and experimentally. The experimental results show that the proposed method performs better than the amplitude-based method, reducing the effect of lift-off distance variation and obtaining an excellent linear measurement range from 24 to 2095 nm. The measurement accuracy is as high as 2.1 nm with an excitation frequency of 1.39 MHz and a large lift-off distance of 3.5 mm. The relative measurement error is less than 1.2% and the endpoint thickness ranges from 100 to 180 nm in the Cu-CMP process, when the lift-off distance varies from 3.6 to 3.3 mm.
An Analysis of Statistical Techniques Applying to Multi-Feature Similarity Comparison between Corpora

Statistical techniques applying to multi-feature similarity comparison belong to the type of goodness-of-fit test which include chi-square test, rank correlation test and Kolmogorov-Smirnov test (K-S test). Experiments show that both chi-square independence test and rank correlation test are subject to the variation of sample size. With the expansion of sample size, the former test achieves the results of significant difference and the latter achieves the results of significant correlation easily. However, both results fail to reveal the actual situation of multi-feature similarity comparison between corpora. Only K-S test, which quantifies a distance between the empirical distribution functions of two samples, can achieve the highest statistical effectiveness.
Complex modulation characterization of liquid crystal devices by interferometric data correlation

A new phase modulation spatial light modulator (SLM) characterization procedure is presented, based on the analysis of the interference fringes of a Mach - Zender interferometer arrangement, by means of correlation and Fourier transform methods. This, accompanied by an amplitude calibration technique that makes use of the same experimental set-up, gives a general measurement procedure for SLM full complex characterization. As an experimental application, two different operation curves of an Epson LCTV are determined, in order to use these configurations for an optical pattern recognition procedure: a phase-only high-efficient joint transform correlator.
Palm Tree Coplanar Vivaldi Antenna Array on the Same Substrate Size: Design and Performance Evaluation

This paper aims to describe the performance of the palm tree Coplanar Vivaldi Antenna Array (CVA) that was simulated from 0.25-6.25 GHz in terms of return loss and radiation pattern. Palm Tree Coplanar Vivaldi Antenna is available in four different configurations: single-element, two-element array, four-element array, and an eight-element array. We create a feeding network and radiator patch for two, four, and eight-array antennas. The simulation results demonstrate that the single-element antenna has the best return loss performance and can cover all frequency work from 0.25-6.25 GHz. In contrast, the antenna array can only cover multiband frequency. At 3 GHz, a single-element antenna has a directivity of 8.77 dBi, a sidelobe level of -2.2 dB, and a beamwidth of 63.70. In contrast, an antenna array of 8 elements has a directivity of 15.5 dBi, a sidelobe level of -12.6 dB, and a beamwidth of 80. Using the same substrate size, by configuring the Vivaldi Coplanar antenna to be an array at a frequency of 3 GHz, the 1×8 array antenna has a 6.73dBi improvement in directivity, a 10.4 dB boost in side lobe level, and a 55.70 enhanced in beamwidth performance compared to a single element. According to the simulation findings, the radiation pattern performance of the. Palm Tree CVA is greater than a single element in the same substrate size. Good directivity, SLL, and beamwidth performance make the proposed Palm Tree CVA array suitable for integration in telecommunication, radar, or cognitive radio applications.
High performance very long wave infrared quantum cascade detector

In this letter, we introduce a very long wave infrared Quantum Cascade Detector (QCD) with a peak response wavelength of 14.5 μm based on a twin-well coupled absorption region design. Different to standard, single transition well QCDs, the twin-well design effectively enhances the absorption strength of the device and broadens the response spectrum to a certain extent. At 77 K, we observed a responsivity of 3.51 mA / W and a Johnson noise limited detectivity of 1×108 Jones. Altogether, this design resulted in detection at temperatures of up to 140 K with a calibrated black-body source by light coupling using a 45° wedge. These high performance very long wave QCDs are expected to provide pollution monitoring, deep space exploration and other applications.
On the determination of the limit cycles using the harmonic balance method

Several methods have been developed to search for limit cycles or bifurcation curves of nonlinear differential equations. Recently, some non-perturbative methods have been proposed. However, the majority of these methods are based on the so-called harmonic balance method. In this paper, we will see how to use the harmonic balance method to obtain information of the number, period, and form of the limit cycles of certain nonlinear equations. The method also gives a sequence of algebraic approximations of the limit cycles. We will also compare our results with other non-perturbative methods. The results can be generalized to other nonlinear differential equations.
