Authors: Moura Cristiane Silva , Imoniana Joshua Onome , Santos Edicreia , Santos Luiz Miguel Renda 
Published: July 2022

This research investigated the effects of individual and contextual factors on the quality of internal audit moderated by emotional intelligence. The research was operationalized from a research instrument consisting of 39 questions, answered by 93 internal auditors from Federal Educational Institutions in Brazil. Descriptive statistics and Structural Equation Modeling were applied. Results showed that individual factors positively and significantly affect the quality of the audit. The work resources, although considered important, did not influence the quality of the audit, unlike the contextual factor of time budget pressure, which affects it positively and significantly. Regarding the moderation of emotional intelligence in individual factors and contextual factors, this was not supported. Thus, concerning the originality, research on the influence of emotional intelligence on the results of the work of the internal auditor is recent in the literatures, this study therefore, boosts the ex ante sources and also support the regulating bodies and practitioners. Finally, as a suggestion for future research, it is recommended that the studies reach the population not investigated in this study, being internal auditors from other sectors of the economy, external auditors or even auditors from the private sector.

Study of dimensional parametersʼ influence on shielding properties of cylindrical shields will allow to optimise the fusion process, as well as to reduce production costs by reducing the material used. The purpose of this work was to compare results of theoretical calculation of shielding effectiveness of an infinite cylindrical shield with the data obtained in real conditions.A cylindrical Ni-Fe shield was synthesised by electrochemical deposition with length of 32 cm, diameter of 4.5 cm and shielding thickness of ≈ 100 µm. The cylinder length was then reduced from 32 cm to 6 cm in 4 cm increments and for each cylinder length shielding effectiveness was measured using three-coordinate Helmholtz field-forming system.The measurement results show that the calculation of shielding effectiveness of infinite cylindrical shield is valid for cylinder lengths l ≥ 18–20 cm. Shielding effectiveness is markedly reduced at values of l ˂ 15 cm.Analysis of data obtained allowed to conclude that it is necessary to determine the correction factor when calculating a cylindrical screen shielding efficiency

Published: July 2022

Solving the problems of spectral processing of single and quasi-periodic signals in measurement and diagnostic systems is directly related to their isolation against the background of external interference or noise. The purpose of this work was to study single and quasi-periodic signals, i. e. signals limited in time, presented as separate components; development of a mathematical apparatus that connects the individual components of the original, time-limited signal, with the spectral characteristics of the periodic signal, which is obtained from the original by its periodization.The paper analyzes the spectrum of a quasi-periodic signal, which is presented from spectral density regions separated by spectral components with zero amplitude. The process of signal periodization is considered on the example of unipolar rectangular pulses. The representation of the analyzed complex single signal in the form of a linear combination of given functions, limited in time by the duration of the considered signal, was chosen, and it was determined that it is most logical and efficient to use radio-frequency pulses. The spectral density of the signal under consideration is presented as the sum of the spectral densities of radio-frequency pulses of the same width with a varying carrier frequency. The original signal is presented as the sum of the constituent components (radio-frequency pulses), which form a time-limited frequency spectrum – a quastr. As a result, the correlation of the considered quasi-periodic signal with the parameters of the periodic signal (amplitude, period, and initial phase) is shown.A format for representing time-limited signals in the form of components related to the spectral characteristics of a periodic signal, obtained from the original signal by periodization, has been developed. The formed mathematical apparatus allows simplifying the algorithmic support of measuring systems by eliminating the correlation signal processing.
Probability of Erroneous Data Registration in a Single Photon Erasure-Type Communication Channel with a Receiver Based on a Photon Counter
Authors: Timofeev A. M. 
Published: July 2022

When measuring low-power optical signals, it is necessary to ensure the highest reliability of the received data, which is especially important for single-photon communication channels. This determines the expediency of using photon counters as receiving modules for such channels. They are highly sensitive, but are characterized by data recording errors. Therefore, the purpose of this work was to investigate the influence of the intensity of the registered optical radiation J0 during the transmission of binary symbols “0” on the probability of registering symbols “1” at the output of the communication channel in the presence of symbols “0” at its input P(1/0).The statistical distributions of the mixture of the number of dark and signal pulses at the output of the photon counter during the registration of binary symbols “0” Pst0 (N ) were determined. To do this, a technique was used to reduce information loss. As a result, the minimum probability P(1/0) was reached.The probabilities P(1/0) were calculated for a communication channel containing a photon counter as a receiving module. This calculation was carried out at different values of the supply voltage of the avalanche photodetector U and the intensity of the optical signal used to transmit the binary symbols “0” J0 .The experimental results showed that with increasing optical signal intensity J0 , the dependences P(1/0) on J0 initially remain almost unchanged and retain a constant value. However, with a further increase in J0 , there is a linearly increasing character of the dependences P(1/0) on J0 . Moreover, with other equal reception parameters, such a character of the dependences P(1/0) on J0 begins to manifest itself at higher intensities of the optical signal J0 with an increase in the supply voltage of the avalanche photodetector.

Published: July 2022

For the manufacture of spring springs of rolling stock (wagons, locomotives, cars), bars made of spring steels are used. With high-temperature machining, when winding springs and quenching them, there is a difference in the cooling rates of the inner and outer sides of the spring coils, which leads to a difference in the structural state and affects the durability of the springs. The aim of the work is to study the effect of structural changes in the outer and inner surfaces of spring steel coils after winding and high–temperature machining operations on the measured characteristics of Rayleigh acoustic waves.The propagation velocities of Rayleigh waves in spring-spring steel 60C2A after winding and hightemperature machining operations are investigated. The shadow method and the autocirculation method with piezoelectric converters CTS-19 with a frequency of 5 MHz with a special block design were used for research. The converters provide input and reception of the Rayleigh wave along the inner and outer forming surface of the spring. It is shown that the method of comparing the results of measuring the velocity of Rayleigh waves on a fi base by the coil generator on the inner and outer surfaces of the spring is sensitive to disturbances in the structure of the material and the appearance of defects. An unambiguous relationship of the structural states on the outer and inner sides of the spring with the velocity of the Rayleigh wave is found.As a result of the measurements, a conclusion was made about the significant sensitivity of Rayleigh waves to the structural state of the steel under study. An increase in the wave velocity was detected on the inner surface of the coil in the contact zone with the mandrel relative to the outer side of the coil, signaling incomplete hardening of steel in this zone during high-temperature machining. The relative speed difference in different spring samples is approximately up to 1 % (≈ 30 m/s), which is a significant value for assessing the quality of high-temperature machining.
A Bayesian Optimization Approach to the Simultaneous Extraction of Intrinsic Physical Parameters fromT1 andT2 Relaxation Responses
Authors: Li Rupeng , Shikhov Igor , Arns Christoph 
Published: July 2022

SummaryNuclear magnetic resonance (NMR) relaxation responses in porous media provide a sensitive probe of the microstructure and yet are influenced by a number of factors which are not easily detangled. Low-field T2 transverse relaxation measurements can be carried out quickly and are frequently used as pore size distributions, while adding T1 longitudinal relaxation measurements provides additional insights into surface properties and fluid content. Here we present an inverse solution workflow extracting related intrinsic physical parameters of the system by fitting experiment and numerical simulation(s). An efficient NMR forward solver for the simultaneous calculation of T1 and T2 responses is introduced, which honors existing inequality relationships between T1 and T2 parameters. We propose a Bayesian optimization approach that jointly identifies T1- and T2-related properties satisfying physical constraints by simultaneously fitting T1 and T2 experiments to simulations. This dual-task inverse solution workflow (DT-ISW) identifies the solution by minimizing the sum of the L2 norm of the fitting residuals of both T1 and T2 distributions into a single objective and jointly models the two highly correlated objectives with high efficiency using the vector-valued Gaussian process (GP) kernel for transfer learning. A multimodal search strategy is used to identify nonunique solution sets of the problem. The workflow is demonstrated on Bentheimer sandstone, identifying five intrinsic physical parameters. The performance of the joint DT-ISW (DT-ISW-J) is compared to a sequential DT-ISW (DT-ISW-S) approach as well as an independent single-task ISW (ST-ISW) of the T1 and T2 responses. Both dual-task versions converge more than two times faster than the single-task version. DT-ISW-J equally minimizes the L2 norm of T1 and T2 fitting residuals whereas DT-ISW-S only preferentially minimizes the objective assigned higher importance. A Pareto optimal solution (POS) is provided to allow operators to subjectively balance the preference of T1 and T2 data fits for the slightly conflicting objectives. The ability to extract five intrinsic physical parameters simultaneously provides new techniques for tracking wettability alteration and assessing the influence of clay amount and distribution on petrophysical property estimates.

Abstract
Aim
Acute kidney injury (AKI) is becoming a heavy health burden worldwide. There are no effective therapeutic strategies nowadays. Recent studies showed that autophagy and lysosome stabilization could inhibit tubular cell apoptosis, and protect against AKI. Annexin A2 (ANXA2), a calcium-regulated phospholipid-binding protein, was found to be highly involved in autophagy. However, its role in AKI has not been elucidated.
Results
We found that ANXA2 is highly increased in renal tubular cells in cisplatin-treated mice, and in the urine and kidney samples from AKI patients. Ectopic expression of ANXA2 promoted lysosomal functions and autophagic flux, and protected against tubular cell apoptosis in AKI mice. Transcriptome analysis further identified that ANXA2 was intimately correlated with lysosome biogenesis, autophagy, and β-catenin signaling. Mechanistically, ANXA2 induced β-catenin activation through binding to and inhibiting on GSK3β, which further triggered T cell factor 4 (TCF4)-mediated transcription factor EB (TFEB) signaling pathway. As a result, TFEB activation regulated lysosomal proteostasis and effectively promoted autophagic flux. This greatly protected against renal tubular cell apoptosis and alleviated AKI.
Innovation:
These findings underline ANXA2 serves as a new therapeutic potential for AKI which lacks effective treatment.
Conclusion
We demonstrated that ANXA2 plays a key role in retarding AKI, which is associated with its inductive effects on β-catenin/TFEB-induced lysosmal pathway.
Hardware-Efficient and Accurately Frequency Offset Compensation based on Feedback Structure and Polar Coordinates Processing

Published: July 2022

Abstract
Compared with off-line digital signal processing (DSP) verification, achieving the expected performance and hardware efficiency in application specific integrated circuit (ASIC) is more critical for DSP to reduce power consumption and cost. The performance of traditional frequency offset compensation algorithms based on feedforward structure is strongly dependent on the accuracy of frequency offset estimation (FOE). Therefore, frequency offset calculation and loop filtering implemented in ASIC or field programmable gate array (FPGA) usually choose high word-width fixed-point operations or floating-point operations, which increase the consumption of logical resources and reduce the clock frequency that hardware logic can achieve. This work proposes a frequency offset compensation scheme based on polar coordinate processing and feedback structure, and a pre-decision-based angle differential estimator (PADE) is used to estimate the residual frequency offset. In the proposed feedback structure, the frequency offset estimator is realized by a simple accumulator, and the input of the accumulator is the residual frequency offset or its scaling, which will reduce the requirement for the accuracy of the residual frequency offset estimator. The offline verification results show that the performance of the proposed algorithm is close to that of the traditional algorithm, but the proposed algorithm has lower logic resource consumption and higher clock frequency in hardware implementation based on FPGA. The performance of the proposed method is evaluated in real-time through 10-Gbps data rate Polarization-multiplexed Quadrature Phase Shift Keying (PM-QPSK) modulation after 20-km standard single-mode fiber (SSMF) transmission. Compared with offline processing in MATLAB®, no hardware implementation penalty is observed.

Published: July 2022

Abstract
This study presents a new technology that can detect and discriminate individual chemical vapors to determine the chemical vapor composition from mixed chemical composition in situ based on a multiplexed DNA-functionalized graphene (MDFG) nano-electrode without condensing the original vapor or target dilution. To the best of our knowledge, AI (Artificial Intelligence)-operated arrayed-electrodes identified the composition of mixed chemical gas with mixed ratio of it in early stage. This innovative technology comprises an optimized combination of nano-deposited arrayed electrodes and artificial intelligence techniques with advanced sensing capabilities that are comparable to the biological limit, resulting to verify mixed vapor chemical components. Highly selective sensors that are tolerant to high humidity levels provide a target for “breath chemo-vapor fingerprinting” for the early diagnosis of diseases. The feature selection analysis achieves recognition rates of 99% and above under low-humidity conditions and 98% and above in humid conditions for mixed chemical compositions. The 1D convolutional neural network analysis performed better with discriminates the compositional state of chemical vapor under low- and high-humidity conditions almost perfectly. This study provides a basis for the use of multiplexed DNA-functionalized graphene gas sensor array and artificial intelligence discrimination of chemical vapor compositions in breath analysis applications.

Abstract
Background: Migraine (MIG) is a common cause of headache and a leading cause of morbidity in Turkey but comprehensive and comparative data evaluating its burden are scarce. The study aimed to describe clinical characteristics and management of MIG and compare MIG with tension type headache (TTH) regarding the burden of disease and healthcare resource utilization. Methods: A total of 1368 patients (aged 18-65 years) with MIG or TTH were surveyed regarding patients’ sociodemographics, headache characteristics, clinical management, burden of disease, quality of life and healthcare resource utilization within the previous 12 months. Data from 1053 patients with definite MIG (dMIG) (n: 924; 87.7%) or definite TTH (dTTH) (n: 129; 12.3%) criteria were analyzed.Results: The frequency and duration of attacks, the number of monthly headache days and of days with analgesic consumption and the severity of headaches were higher in dMIG than in dTTH (p:0.005 for the frequency of attacks and p<0.001 for the others). The benefits from acute medications decreased as the monthly headache days increased in dMIG: 70.9% (1-3 days); 35.9% (4-7 days); 22.1% (8-14 days) and 18.1% (>14 days). Only 222 (36.8%) of definite migraineurs who experienced ≥4 monthly headache days were on preventive treatment. Migraine Disability Assessment (MIDAS) scores were higher in dMIG than in dTTH (24.7±40 vs 10.6±12; p<0.001). The negative impact on the quality of life and the economic loss were also higher with dMIG (p<0.001 for both). More patients with dTTH visited a physician in the previous year (86.8% vs 77.6%; p:0.016) but the number of physician visits were higher in dMIG (3.5 ±5 vs 1.7 ± 1; p < 0.001). The groups were comparable regarding the percentage of patients who had a radiological investigation due to headache but patients with dMIG had more brain magnetic resonance imaging and computed tomography scans (p<0.020 and p<0.003, respectively). Conclusions: It is crucial to timely and correctly diagnosing and optimally managing MIG due to its significant burden. Educational programmes for patients and healthcare providers, adherence and persistence to preventive medications may improve clinical outcomes.

Abstract
We propose a two-way detection network(TWD-Net) for active stereo matching. We design a depth reconstruction model of binocular speckle structured light based on self-supervised learning. First, the network achieves a dual model and obtains left and right disparity respective. Then, we propose an image-guided filtering method to optimize the edge of rough disparity. Finally, we detect the consistency based on the disparity images and establish the two-way detection loss function.

Abstract
Background
Pharmacogenomics (PGx) was one of the first genomics applications to hold promise in precision medicine. The cost-effectiveness of PGx has been estimated for many disease states, with the strongest evidence supporting the use of PGx-guided testing to inform prescribing for cardiovascular diseases. Most studies do not consider the presentation of test results in clinical workflow using a clinical decision support (CDS) system. We previously developed a cost model that found that implementation costs of a PGx-CDS system may constitute a non-trivial proportion of the cost of a PGx program. We recently extended that model to include clinical and cost-effectiveness outcomes, using clopidogrel and warfarin as prototypes. In contrast to CDS that occurs at the level of the individual patient, our approach delivers “administrative decision support”, which can help leaders make informed decisions about the programmatic costs of PGx-CDS implementation. In this manuscript, we describe our efforts to develop an interactive version of our model and host it on a publicly available, interactive web platform. We built the web application of the PhaRmacogEnomics ClInical Support Economic Value (PRECISE-Value) model using shiny/shinydashboard packages in the R software environment. We incorporated user defined, customizable input values expected to differ between health-systems: population size, age/race distribution, number of patients tested, and information technology costs. Dynamic, user manipulation of these values reveals the designated outcomes of adverse drug events and deaths averted, costs, and an incremental cost-effectiveness ratio. Summary and detail tabs, a data dictionary and a cost-effectiveness primer are provided. Six PGx decision makers tested and provided feedback on our web application.
Results
Users suggested the application is easy to use and accomplishes the stated goals of presenting useful information for decision-makers. Given the prevalence of PGx test panels, all panel members expressed the desire to add additional drug-gene pairs and further tailor inputs by health-system-specific parameters.
Conclusions
Our interactive, web-based application of our prototype model of the cost-effectiveness of implementing a PGx-CDS system for clopidogrel and warfarin was deemed useful by an expert panel for informing decision makers as they consider the value of implementing a CDS program based on PGx test results.
