End-to-End Wireless Communication System Based on Deep Neural Network Channel Module
Authors: Ganchev Ivan , Ji Zhanlin 
Published: October 2022

<p> The existing end-to-end (E2E) wireless communication systems require fewer communication modules, have a simple processing signal flow and do not require expertise compared to conventional wireless communication systems. However, in the absence of a differentiable channel model, it is impossible to train transmitters, used in such systems, which makes impossible to get optimal system performance. To solve this problem, an E2E wireless communication system with conditional generative adversarial networks (CGAN) for channel modeling has been proposed recently. Unfortunately, the training of CGAN is prone to instability, slow convergence, and inaccurate channel modeling, which affects the system performance. To this end, we propose an E2E wireless communication system with a deep neural network (DNN) channel module as the unknown channel. Simulation results showed that the proposed channel modeling method has faster convergence, simpler network structure, and can reflect the behavior of real channels more accurately. In addition, the proposed E2E wireless communication system exhibits better bit error rate (BER) and block error rate (BLER) performance. </p>

Daerah Katingan Kalimantan Tengah dilihat dari Atlas Peta Sebaran Tanah Lunak di Indonesia umumnya didominasi dengan tanah lempung lunak yang memiliki daya dukung umumnya rendah sehingga dapat berpotensi menimbulkan kendala dalam pekerjaan konstruksi berupa perosokan (settlement). Oleh sebab itu pada penelitian ini dilakukan studi mengenai korelasi antara nilai CBR (California Bearing Ratio) dan Kuat Tekan Bebas Tanah Lempung di Daerah Kampung Banjar Kecamatan Kasongan Kabupaten Katingan. Pengujian ini dilakukan untuk mengetahui karakteristik fisik dan dan mekanis tanah asli. Data yang didapatkan kemudian dilakukan analisis data dengan mencari hubungan satu sama lain (korelasi) menggunakan regresi linear atau dengan menggunakan regresi yang paling sesuai untuk mendapatkan hubungan antar parameter yang berguna untuk memperkirakan nilai CBR laboratorium dan Kuat Tekan Bebas. Berdasarkan pengujian yang telah dilakukan didapatkan nilai kuat tekan bebas pada 5 titik di daerah Kampung Banjar Kecamatan Kasongan Kabupaten Katingan yakni 0,580 kg/cm2; 0,485 kg/cm2; 0,518 kg/cm2; 0,550 kg/cm2; 0,548 kg/cm2. Sedangkan nilai %CBR pada masing-masing titik yakni 3,08%; 3,02%; 4,05%; 5,01%; dan 6,30%. Dari nilai tersebut didapatkan korelasi antara nilai kuat tekan bebas dan California Bearing Ratio (CBR) menggunakan persamaan regresi liner yakni %CBR = 1,872 qu + 2,0102.

The Katingan area, Central Kalimantan, as seen from the Atlas of Soft Soil Distribution Map in Indonesia is generally dominated by soft clay soils which have generally low bearing capacity so that they can potentially cause obstacles in construction work in the form of settlements. Therefore, in this study, a study was conducted on the correlation between the value of CBR (California Bearing Ratio) and the unconfined Compressive Strength of Clay in the Banjar Village, Kasongan District, Katingan Regency. This test was conducted to determine the physical and mechanical characteristics of the original soil. The data obtained are then analyzed by looking for relationships with each other (correlation) using linear regression or by using the most appropriate regression to obtain relationships between parameters that are useful for estimating laboratory CBR and unconfined compressive strength. Based on the tests that have been carried out, the value of the unconfined compressive strength at 5 points in the Banjar Village, Kasongan District, Katingan Regency is 0.580 kg/cm2, 0.485 kg/cm2, 0.518 kg/cm2, 0.550 kg/cm2, 0,548 kg/cm2. While the %CBR values ​​at each point are 3,08%, 3,02%, 4,05%, 5,01%, dan 6,30%. From this value, the correlation between the value of unconfined compressive strength and the California Bearing Ratio (CBR) was obtained using a linear regression equation is %CBR = 1,872 qu + 2,0102.

Published: October 2022

Summary. The aim is to determine simple, easily accessible criteria for assessing the severity and prediction of the course of purulent processes.
Materials and methods. 161 patients with purulent processes were examined. The dependence of the duration of treatment on the type of pathology, sex, age, body temperature, the number of leukocytes in the peripheral blood, the presence of pathological changes in the urine, the duration from the onset of the disease to the beginning of treatment was studied. Signs were coded in points. The rank correlation coefficient (ρ) between the duration of treatment and the above symptoms, its error (mρ) and the confidence criterion (t) were calculated.
Research results and their discussion. A strong and direct relationship was noted between the nature of the pathology, body temperature, age of the patient and duration of treatment (р˂0.001). The presence of pathological changes in the urine, leukocytosis has a medium-intensity connection with the duration of treatment and a reliable correlation (р˂0.05). The average duration of treatment was 15.2±0.5 days. If this duration is taken as the limit in the case of a favorable course, then the prognosis is favorable for patients who have a total score of the specified criteria of no more than 24. In patients with a total score of more than 24, the prognosis is serious. They are shown radical surgical treatment of the abscess, combined antibiotic therapy, detoxification therapy, and intensive local treatment.
Conclusions. To assess the severity of a case of purulent-inflammatory disease, determine the prognosis and develop treatment tactics, informative signs are the nature of the pathology, the temperature reaction, the age of the patient, the number of leukocytes in the peripheral blood, and pathological changes in the urine. These criteria can also be used for comparative characteristics of different groups of patients.
COMPARISON OF THE RESULTS OF RADIOFREQUENCY ABLATION AND PHLEBECTOMY OF SUPRAFASCIAL SEGMENTS OF THE GREAT SAPHENOUS VEIN IN PATIENTS WITH VARICOSE DISEASE OF THE LOWER EXTREMITIES
Authors: Pertsov V. I. , Mamunchak O. V. 
Published: October 2022

Summary. Introduction. Over the past two decades, such traditional surgical procedures as crossectomy and stripping have been replaced to a greater or lesser extent by less invasive endovenous methods. Unfortunately, endovenous ablation methods do not allow to completely exclude such complications as: hyperpigmentation, paresthesias, hematomas, thermal damage to the skin.
Purpose.To improve the tactics and improve the cosmetic effect of surgical treatment of superficially located suprafascial segments of the great saphenous vein in patients with varicose veins of the lower extremities.
Materials and methods. An analysis of the treatment of 107 patients with VDLE at the University Clinic of ZDMU in 2019-2021 was carried out. The first (main) group – 65 (60.75 %) patients – received surgical treatment according to the proposed method – RFA, miniphlebectomy of the suprafascially located main trunk, miniphlebectomy of the tributaries along the Varada. The second (comparison) group – 42 (39.25 %) patients – received standard treatment – RFA of the GSV trunk, miniphlebectomy.
Research results. According to the control duplex scan in all patients, the deep vein passage was occluded in 106 (99.1 %) patients.
The overall frequency of postoperative complications in the main group was 18.4 % (12 out of 65 patients), in the comparison group – 35.7 % (15 out of 42 patients, mainly due to hyperpigmentation) and was significantly different (р ˃ 0.05).
According to the data of CIVIQ-2, the proposed method of surgical intervention made it possible to improve the quality of life from (31.72 ± 1.56) points in patients of the comparison group to (27.49 ± 1.45) in patients of the main group.
Conclusions. The proposed tactic of surgical correction of the varicosity of the trunk of the GSV – RFA of the intrafascial area of the GSV plus miniphlebectomy of the suprafascial segment – allows to reduce the probability of the development of hyperpigmentation, which contributes to a better cosmetic effect, subjective satisfaction of patients with the results of the operation, and a better quality of life in patients with VDLE.
COMBINATION OF THE MULTIMODAL ALGORITHM AND THE RECONSTRUCTIVE-RESTORATIVE LADDER IN THE TREATMENT OF THE WOUNDED WITH FLAMMABLE DEFECTS SOFT FABRIC

Published: October 2022

Resume. Most wounds formed as a result of a gunshot wound require staged, and in some cases, multistage reconstructive and restorative operations and rehabilitation.
Materials and methods. During treatment at the Military Medical Center of the Republic of Poland for 6 months (from 24.02.22 to 10.09.22), reconstructive and surgical treatment of 54 wounded soldiers was carried out using the principles of reconstructive and plastic surgery. The treatment process was based on a multimodal approach - dynamic screening of gunshot wounds with soft tissue defects, which was used in the pre-, intra- and postoperative periods.
Results and their discussion. A total of 54 wounded people were included in the study. Methods of closure that were used during the recovery process: spontaneous epithelization — 3 (5.6 %) of the injured, secondary sutures — 10 (18.5 %), PHO with the use of a split skin flap - 12 (22.2 %), sliding flaps – 12 (22.2 %), propeller flaps – 17 (31.5 %). When using full-layer flaps (sliding, propeller) in wounded patients, inflammatory complications were not observed in the postoperative period, but the phenomena of venous stasis, marginal necrosis of the distal part of the flap were noted. The average number of postoperative bed days before independent movement or self-care was 7.5 days. The aesthetic component in wounded patients with the use of flaps increased by 1.8 times compared to the RSK technique.The functional component was restored in 35 % during further observation.
Conclusions. As the experience of the VHP in previous military conflicts has shown, primary closure of a gunshot wound is not possible, and in some cases even harmful. Therefore, in our opinion, the preparation of a gunshot defect of soft tissues, based on multimodal monitoring, can be considered as a bright addition to the reconstructive-plastic ladder. Performing reconstructive and plastic closure of gunshot wounds with propeller flaps is an actual method of restoring the damaged anatomical area, which allowed to obtain better aesthetic, as well as anatomical and functional results, in some cases - without additional wound surfaces (places for the collection of RAS).

Experiment was conducted on mango at ICAR-Indian Institute of Soil and Water Conservation, Dehradun during 1995-2020. Mango cultivar ‘Mallika’ was the most vigorous and attained maximum plant height (6.80 m), canopy volume (220.25 m3) produced highest fruit yield (90.81 kg tree-1), litter production (5.35 tha-1), fine root production (847.21 g m-2 yr-1) and conserved 10.90 cm moisture in the soil profile upto 1.20 m depth. Whereas the lowest plant height (4.50 m), canopy volume (147.73 m3) in Amrapali cultivar, soil moisture conservation and lowest fruit yield (50.31 kg tree-1) in Ramkela were recorded in 25 years of orchard life and 20 Year of fruiting life of mango. The maximum fruit qualities like fruit weight (g), pulp content (%), totals soluble solids (0Brix), total sugar (%), reducing sugar (%), non-reducing sugar, β carotene (%) in Mallika cultivar whereas maximum acidity (%) and Vit.-C in Ramkela cultivar of mango were observed during 1995-2020 on degraded lands. The biomass productivity comprising stem, branches and roots was the highest in Mallika (82.37 Mg ha-1), carbon stock (40.02 Mg C ha-1) with carbon sequestration rate (1.60 Mg C ha-1yr-1) followed by Bombay green (1.50 Mg C ha-1yr-1) and Langra (1.48 Mg C ha-1yr-1). Net present value of mango cultivars ranged from 32,068 USD in Mallika to 20,514 USD in Bombay Green cultivars of mango. The benefit cost ratio ranged from 3.26 (Mallika) to 2.0 (Bombay Green), thereby presenting adequate choice to the cultivators / growers to select the appropriate cultivars for specialization. The Mallika cultivar of mango outperformed considering demand of pulp/juice industries and Ramkela cultivar well qualified for pickle industries under degraded lands.
