Universal Joint Source-Channel Coding Under an Input Energy Constraint
Authors: Lev Omri , Khina Anatoly
Published: January 2023

We consider the problem of transmitting a source over an infinite-bandwidth additive white Gaussian noise channel with unknown noise level under an input energy constraint. We construct a universal scheme that uses modulo-lattice modulation with multiple layers; for each layer, we employ either analog linear modulation or analog pulse position modulation (PPM). We show that the designed scheme with linear layers requires less energy compared to existing solutions to achieve the same quadratically increasing distortion profile with the noise level; replacing the linear layers with PPM layers offers an additional improvement.

Published: January 2023

Sensitivity of lidar metrics to scan angle can affect the robustness of area-based approach (ABA) models, and modelling the interplay of scan geometry and terrain properties can be complex. The study hypothesises that neural networks can manage the interplay of lidar acquisition parameters, terrain properties, and vegetation characteristics to improve ABA models. The study area is in Massif des Bauges Natural Regional Park, eastern France, comprising 291 field plots in a mountainous environment with broadleaf, coniferous, and mixed forest types. Field plots were scanned with a high overlap from multiple flight lines and the corresponding point clouds were considered independently to expand the standard ABA dataset (291 observations) to create a dataset containing 1095 independent observations. Computation of lidar, terrain and scan metrics for each point cloud associated each observation in the expanded dataset with the scan information in addition to the lidar and terrain information. A multilayer perceptron (MLP) was used to model basal area and total volume to compare the predictions resulting from standard and expanded ABA datasets. With expanded datasets containing lidar, terrain and scan information, the R² for the median predictions per plot were higher (R² of 0.83 and 0.85 for BA and Vtot) than predictions with standard datasets(R² of 0.66(BA) and 0.71(Vtot)) containing only lidar metrics. It also outperformed an MLP model for a dataset with lidar and terrain information (R² of 0.77 (BA and Vtot)). The MLP performed better than RF regression, which could not sufficiently exploit additional terrain and scan information.
Improve the performance of convolutional GAN using history-state ensemble for unsupervised early fault detection with acoustic emission signals
Authors: Wang Yu , Vinogradov Alexey
Published: January 2023

Early fault detection (EFD) in run-to-failure processes plays a crucial role in condition monitoring of modern industrial rotating facilities, which are more and more demanding for safety, energy and ecology saving and efficiency. To enable effective protecting measures, the evolving faults have to be recognized and identified as early as possible. The major challenge is to distill discriminative features on the basis of only the ‘health’ signal, which is uniquely available from various possible sensors before damage sets in and before the signatures of incipient damage become obvious and well-understood in the signal. Acoustic emission (AE) signal has been frequently reported to be able to deliver the early diagnostic information due to its inherently high sensitivity to the incipient fault activities, offering great potential of the AE technique for EFD, which may outperform the traditional vibration-based analysis in many situations. Up to date, the ‘feature-based’ multivariate analysis dominates the interpretation of AE waveforms. In this way, the decision making relies heavily on expert’s knowledge and experience, which is often a weak link in the entire EFD chain. With the advent of artificial intelligence, people are seeking for intelligent method to tackle this challenge. In this paper, we introduce a versatile intelligent analysis method for AE signals. A new architecture of convolutional generative adversarial network (GAN) is designed to extract deep information embedded in AE signals. In order to improve the robustness of the proposed EFD framework, a novel ensemble technique referred to as ‘history-state ensemble’ (HSE) is introduced in this paper. Primary merits of HSE are highlighted as: (1) it does not require extra computing time to obtain the base models; (2) it does not require special design on the network architecture and can be applied to different networks. To evaluate the proposed method, a rolling contact fatigue test monitored by AE sensors was performed, and experimental results have demonstrated the proposed ensemble method largely improves the robustness of GAN. 
A New Technique for Gain and Timing Calibration in Time-Interleaved ADCs Using an Estimation Signal
Authors: Issvand Nassiri Mohammad
Published: January 2023

Abstract—This paper proposes a new technique to identify the mismatch error in time-interleaved analog-to-digital converters. This is done by injecting an estimation signal comprising of two parts; one section for identifying gain mismatch error and another one for timing mismatch error. Passing through the TI-ADC's channels, the estimation signal is influenced by the non-ideal sampling, which distorts the signal by adding some spurs in the output. This technique detects the mismatch error by extracting the spurs attached to the estimation signal with no interruption in data conversion. Since this method does not depend on feedback has high speed convergence. A simple gain and derivative filter are employed to compensate the identified mismatch error. Simulation results show that SFDR is improved by 23.2 dB in a two-channel TI-ADC. Moreover, the gain and timing mismatches are identified with just 265 samples after simulation running. The ripples on the identified error are maximally 0.4 % of the precise mismatch error of the converter.

In this article, an X-band metasurface is designed and this metasurface array is used as an instrument to increase gain & reduce radar cross section of circularly polarized X-band MIMO antenna through super-state and under-state positioning of array respectively. Absorbance of the metasurface to the intended frequency band (i.e., 6.75GHz-14.0GHz) is more than 90.0%. Metasurface is designed on FR-4 substrate height (Hs) 3.1mm with unit cell dimension of 7.95×7.95×3.1mm3 (0.265λo×0.265λo×0.103λo) at 10GHz. The proposed antenna is also designed on FR-4 substrate with dimensions of 29×23×1.6mm3 (0.966λo×0.766λo×0.0.053λo) at 10GHz. The super-state and under-state positioning of metasurface array over MIMO antenna is increased the gain (peak gain 12.6dBi at 11GHz) and reduced the mono-static RCS (18dBm2) across the band respectively. The characteristic of the antenna is likewise verified by its s-parameters, radiating efficiency, gain and diversity parameters for the intended band. The simulated & measured results are having better harmony which exhibits suitability of the proposed designs for IoT over satellite, military application, and also useful to identify blood clouting in CT-scan application.

Objective: Tuberculous epididymis TB introduced as a colossal scrotal ulcer with scrotal sack inclusion is extraordinarily remarkable. The side effects of such ITE look like the epididymo-orchitis or dangerous tumor, which results in misdiagnosis or defer in conclusion. Methods: This study is a review information examination of 16 instances of histologically-affirmed epididymal tuberculosis in patients treated at IBN-SINA medical clinic from March 2015 to December 2022. Results: The age of the patients was normal around 42 years (range, 24-62 years); 5 patients (31.25%) had tuberculosis in the left epididymis, 7 patients (43.75%) had tuberculosis in the right epididymis and 4 patients (25%) had two-sided epididymal tuberculosis. Of the 16 patients, 3 patients (18.75%) had a past filled with tuberculosis, including 1 instance of pneumonic tuberculosis, 1 instances of renal tuberculosis and one instance of prostate tuberculosis. Conclusion: Epididymal tuberculosis is probably going to have attacked encompassing tissues when signs, for example, epididymal beaded changes and not well characterized epididymis-testis line are available. Careful treatment joined with preoperative and postoperative anti-tubercular treatment is a successful way to deal with treating this condition. Sperm retrieval and cryopreservation must be considered for potential intra-cytoplasmic sperm infusion.

The article shows that experimental infection of sheep with melaphagosis leads to significant structural disorders in the skin and liver. There is local necrosis in the liver. In this case, hepatocytes lose their cytolemma, and the cytoplasm of the cells merges to form a homogeneous mass. Cell nuclei undergo karyopyknosis, chromatin is strongly compacted and is located in small groups in a uniform mass of destroyed hepatocytes. Next to necrotic hepatocytes are hepatocytes with poorly defined cell boundaries. At the same time, hepatocytes lose their orientation, that is, they do not form liver plates. Some of them still retain a pronounced nucleus, the karyolemma. Sometimes changes in the liver cover a vast area and in such areas hepatocytes are at different stages of destruction. In the interlobular connective tissue of the liver, extensive areas with accumulations of lymphoid tissue are revealed. Blood vessels, especially sinusoidal capillaries, are characterized by plethora and perivascular edema. Blood stasis is accompanied by adhesion of leukocytes to endotheliocytes and gradual migration of leukocytes into the perivascular zone. The use of Mediatrin to combat bloodsuckers leads to the elimination of the cause of destruction in the body, but the drug itself has side effects. In sheep, after Mediatrin, destructive processes in hepatocytes remain in the liver, but less swelling and cellular reaction are visible. In the treatment of Mediatrin + Eracondom, clusters of lymphoid cells are still found in the interlobular connective tissue, their number is small, they are mainly concentrated in the area of the liver triad. When Mediatrin + oxymethyluracil (OMU) is added to sheep feed, large foci of necrosis are not detected in the liver. However, individual hepatocytes do not have a clear boundary. In the vast majority of cases, hepatocytes have a cubic or polygonal shape, the nuclei are located in the central zone, the nucleoli are well defined, the chromatin is homogeneous and evenly distributed. Thus, in all experimental groups of sheep, when treated with Mediatrin + Eracond or OMU, a pronounced positive trend in the histological structures of the liver is determined.

The article presents materials for the assessment quality and safety of compound feedstuff for farm animals and poultry. In the structure of the cost of livestock products, a significant share about 70 % is occupied by feed. The efficiency of the livestock sector, further growth rates of the industry are largely determined by the quality of feed components, their availability for domestic agricultural enterprises. The compound feedstuff industry is inextricably linked with the production of livestock and poultry products. Therefore, the prevailing trends in these sectors are directly reflected in the compound feedstuff industry. All feed for farm animals must be subjected to laboratory control for compliance with quality and safety. Feed quality and safety control is carried out in accordance with regulatory documents that establish mandatory requirements aimed at preventing animal diseases, producing complete and veterinary safe livestock products and protecting the population from diseases common to humans and animals. According to organoleptic and physicochemical indicators, combined feeds must comply with GOST R 51899-2002 Granulated compound feedstuff. General specifications. The most important indicators in determining feed safety are the content of mycotoxins (aflatoxin B1, patulin, deoxynivalenol, ochratoxin, T-2 toxin), nitrates, nitrites, toxic elements (mercury, cadmium, lead, arsenic).

Diseases of cattle, accompanied by abortions, proceed as mixed infections. They are caused by viral and bacterial agents or a combination of both. To develop an effective method for diagnosing and treating intrauterine infection in farm animals, it is necessary to create a biological model. In the course of experimental work, we developed an original method of intrauterine infection of pregnant rabbits using a daily culture of E. coli at a concentration of 1 billion/ml, which was injected through the cervical canal using a classic milk catheter connected through an adapter to a disposable syringe. All manipulations were performed under ultrasound guidance. A technique has been developed that, based on the determination of the amount of nitrites and NO2 – + RNO in plasma, can be used to diagnose intrauterine pathologies and monitor their treatment.

The flavivirus family (from Lat. flavus – yellow) represents a significant group of viruses circulating among vertebrates and insects, consists of three genera, one of which is the genus Pestivirus (classical swine fever virus, viral diarrhea (BVD) of cattle, borderline sheep disease, etc.). Viral diarrhea of cattle is a widespread infection in the world, and It is one of the most difficult economic problems in animal husbandry. The clinical picture of BVD is diverse: respiratory organ damage, fever, leukopenia, thrombocytopenia, enteritis, immunosuppression, the virus passes through the placenta, which leads to the birth of persistently infected calves, abortions in cows at all stages of pregnancy are noted, fetal mummification, producing bulls can be virus carriers and secrete the virus with sperm. For serodiagnostics of viral diarrhea of cattle in laboratory practice, ELISA (enzyme immunoassay), RNGA (indirect hemagglutination reaction), PH (neutralization reaction) are used - the gold standard of diagnostics. The PH method is universal and makes it possible to detect the level of virus neutralizing antibodies for making a retrospective diagnosis, evaluating animals for virus transmission and confirming well-being. The PH method is unique and is the only correct one in assessing the effectiveness of vaccines, since only when it is used, the level of virus neutralizing (protective) antibodies protecting animals from direct infection is revealed. The aim of our research was to formulate a neutralization reaction to the detection of antibodies to the bovine viral diarrhea virus using transplanted cultures of PT-80 and KST cells.

The aim of our study was to investigate the possibility of forming the microbiota of the cecum of rabbits with increased content of cellulolytic bacteria Butirivibrio fibrisolvens, due to the transfer of the contents of the rumen of ruminants. To solve this problem, experimental (n=15) and control (n=15) groups of rabbits aged 12 days were formed. In the experimental group, for 14 days the rabbits were tube-feed with a solution of cattle rumen content filtered from coarse undigested feed particles in 1-2 ml diluted 1:1 in physiological solution. To determine the level of cellulosolytic bacteria Butirivibrio fibrisolvens, feces were collected in sterile eppendorfs on day 14 of the study. The presence of cellulosolytic bacteria in cattle rumen content as well as in rabbit feces was determined by real-time polymerase chain reaction. Real-time PCR results showed that the highest fluorescence values were in the rumen contents and at cycle 40 the fluorescence intensity was 1742.60, in the experimental group it was 1059.98 and in the control group without tube-feeding it was 664,50. Thus, it was shown that by feeding cattle rumen content in the early postnatal period in rabbits can form the gut microbiota with an increased content of cellulolytic bacteria Butirivibrio fibrisolvens.

The conditions of industrial poultry farming provide for technological and preventive measures that inevitably cause a weakening of the protective systems of the organism of reared birds. The increasing infectious load, the refusal to use antibiotics, are forcing veterinary specialists to improve existing ones and look for new ways to prevent diseases. The immune system, as one of the regulatory systems, directly or indirectly affects all processes occurring in the body. The use of substances that affect the links of immunity, as well as having other useful properties, can certainly find its place in poultry farming. In the review, special attention is paid to synthetic immunomodulators, for which Azoxivet is a striking example.

Whole milk substitutes are widely used in feeding calves in the dairy rearing period, when the use of whole milk is unacceptable due to diseases of contagious etiology of mothers, or for economic reasons. The purpose of our research was to determine the effectiveness in calf feeding of the new substitute for whole milk «NutrilactPro» developed within the Rusagro group of companies in comparison with analogues designed for use from the first days of life of calves. Scientific research was conducted in the Moscow region. Using the paired-analogues method, two groups of calves of Holsteinized black-motley breed were formed, 12 calves in each group having the same body weight and a group cage housing. Blood samples were taken for clinical and biochemical analysis before and after the experiment. Calves were reweighed every 15 days.

The increasing use of agricultural machines in most mechanized farming fields has led to amplified soil compaction levels due to wheel traffic. Since wheel traffic is still underestimated, the main objective of this research was to determine the effect of wheel traffic on soil physical properties. This research determined the effect of wheel traffic on bulk density, soil texture, porosity, infiltration rate, hydraulic conductivity, and cone index using a field experiment at Egerton University Tatton Farm. A walking tractor was used to provide traffic loads. The experiment was conducted in a completely randomized design (CRD) with three weight applications and three traffic locations. The treatments were 1.72 kN (one tractor pass), 5.15 kN (three tractor passes) and 8.09 kN (five tractor passes) and three traffic locations, which are traffic on rows (TR), traffic between rows (TB) and traffic on the entire row (TE), replicated three times. Average moisture contents of the soil for depth ranges of 0 to 15 cm, 16 to 30 cm and 31 to 45 cm were recorded as 23%, 25% and 27%, respectively. The applied weight significantly increased bulk density and cone index but decreased infiltration rate, hydraulic conductivity and porosity. Bulk density increased by 17%, 15% and 8%, cone index increased by 44%, 10% and 7%, and porosity decreased by 25%, 23% and 36% for the three depth ranges after the three weight treatments were applied, respectively. Hydraulic conductivity decreased from 65.2 cm/day, 50.98 cm/day, and 34.05 cm/day to 13.95 cm/day, while infiltration rates decreased from 0.047 cm/min, 0.031 cm/min, and 0.018 cm/min. TE had the highest bulk density as compared to TB and TR. Analysis of variance indicated changes in weight applied, traffic location, and depth with significant effects on soil properties at a 5% level of confidence. It was concluded that wheel traffic causes soil compaction at varying levels depending on the applied weight, thus affecting the soil physical properties. This suggests that decreased and controlled wheel traffic could be a promising way to alleviate soil compaction.
