The application of the Single Sided Laplace Transform and Fourier Transform embodied within Double Sided Laplace Transform by using generalized functions, eliminating regions of convergence restraints Item
Authors: Khera Roland 
Published: July 2023

<p>The Double-Sided Laplace Transform (DSLT) and the Fourier Transform (FT) are the same at s=jω, but the Unit Step function (Heaviside Function), U(t) does not have the same DSLT and FT at s=jω. This is now solved. It will be shown that the DSLT of f(t) (sgn t)/2 is the Single-Sided Laplace transform (SSLT) of f(t). With the use of generalized function (in particular the complex delta function and its derivatives), the DSLT can be used where ever SSLT and FT are used in engineering applications. The SSLT of an even rational function is shown to be odd, and visa-versa. The problem of the region of convergence in the “s” complex plane is eliminated by including the complex delta function for solving divergent DSLT integrals. The solution for solving divergent integrals are already well established for solving divergent integrals for FT by using the real delta function. An example is provided for solving the Phase Retrieval problem exactly by measuring the signal's even and odd components autocorrelation functions. This has not been possible with the use of the SSLT because one is then only considers cases for time greater than zero, whereas an even and odd function in time needs to be both positive and negative.</p>
Multi-Scale Feature Reconstruction and Inter-Class Attention Weighting for Land Cover Classification
Authors: Wang Xin 
Published: July 2023

<p>Land cover classification has the goal to attribute each pixel of high-resolution remote sensing image with planimetric category labels (such as vegetation, building, water etc.). In recent years, many serial learning architectures (features are delivered through a single path such as in <em>ResNet</em>, <em>MobileNet</em>, <em>Segformer</em> etc.) based on Convolutional Neural Networks (CNN) and attention mechanisms have been widely explored in land cover classification. However, high-resolution remote sensing images typically have abundant textual details, variable scales in objects, large intra-class differences and similar inter-class distances, which brings challenges to land cover classification. In this work, we presented two pluggable modules to further boost serial learning architecture: first, to cope with ambiguous boundaries caused by lost details and fragmented segmentation stemmed from scale variances, a combination of channel attention and spatial attention is proposed to reconstruct multi-scale feature; Second, to mitigate the classification error caused by intra-class variance and inter-class correlation, we build feature vectors for each category, and apply a multi-head attention model to capture self-attention dependence among different categories. The experimental results demonstrate that the proposed modules are feasible to existing serial learning architectures and can improve OA by 5.64% on the ISPRS Vaihingen 2D dataset (using <em>ResNet50</em> as backbone). In addition, compared to other state-of-art models, our method can achieve similar or even better classification results, yet offer superior inference performance </p>
A Deep learning estimation for probing Depth of Transient Electromagnetic Observation
Authors: Tang Rongjiang , Gan Lu , Li Fusheng , Shen Fengli 
Published: July 2023

<p> The probing depth of transient electromagnetic method (TEM) refers to the depth range at which changes in underground conductivity can be effectively detected. It typically ranges from tens of meters to several kilometers and is influenced by factors such as instrument parameters and the conductivity of the subsurface structure. Rapid and accurate calculating the probing depth is beneficial for determining the feasibility of exploration engineering, setting appropriate inversion parameters and improving exploration accuracy. However, mainstream methods suffer from issues such as low computational precision, large uncertainties, or high computational requirements, making them unsuitable for processing massive airborne electromagnetic data. In this study, we propose a prediction model based on deep learning that can directly compute the probing depth from the TEM responses, and its effectiveness and accuracy is validated through synthetic models and field measurements. Furthermore, we apply this algorithm to deep learning-based ATEM inversion by constraining the one-dimensional resistivity models in the training set above the probing depth, to reduce the non-uniqueness of the inversion, accelerate the convergence, and improve its prediction accuracy. </p>

Background: Malignant pleural effusion (MPE) has a variable survival rate and prognosis. The LENT score is one method for assessing survival rates in patients with MPE. This study aimed to investigate the LENT score as a prognostic factor for overall survival (OS) and progression-free survival (PFS) of patients with MPE at a tertiary hospital in West Sumatera.
Methods: This study was an observational analytic study involving several tertiary hospitals in West Sumatera with a minimum observation period of 2 years. Data were collected from medical records. We used Kaplan Meier analysis to assess OS and PFS.
Results: A total of 198 subjects met the inclusion criteria. Most MPE patients in this study were aged ≥60 years, male, smokers, pleural fluid lactate dehydrogenase value <1500, ECOG 1, serum NLR value <9, and high-risk cancer, namely lung cancer. The distribution of LENT scores for MPE patients was evenly distributed among the low, medium, and high-risk groups. Kaplan Meier analysis showed that the median OS based on LENT scores were 804 days, 275 days, and 161 days, respectively (log-rank test p = 0.000). The median PFS based on LENT scores were 715 days, 202 days, and 106 days, respectively (log-rank test p=0.000). The OS and PFS findings are longer than previous studies.
Conclusion: Based on LENT scores, overall survival and progression-free survival MPE patients at tertiary hospitals in West Sumatera have a better prognosis compared to previous studies.

Authors: Tsarkov P. V. , Nekoval V. M. , Tulina I. A. , Balaban V. V. 
Published: July 2023

Introduction: the lack of comprehensive screening programs for colorectal cancer detection in oldest-old steadily leads to an increase in the diagnostic interval (DI), i.e. the time from the patient’s first presentation of complaints until diagnosis and treatment. At the same time, worsening the general somatic condition and developing the decompensation of concomitant diseases. Thus, patients with long-term DI need additional measures while preparing for surgery; the preoperative bed-day increases.Purpose of the study: to evaluate the impact of the diagnostic interval on the short-term results of II and III stages right colon cancer treatment in geriatric patients.Materials and methods: a retrospective multicenter study was conducted at the surgical facilities of Sechenov University from 2006 to 2015. The study included patients aged over 75 who have undergone surgical treatment of II and III stages right colon cancer. The control group comprised patients with CRC diagnosis in the period from 0 to 6 months; the studied group involved patients with a diagnostic interval over than 6 months.Results and conclusions. Analysis of the results revealed that patients older than 80 years had a longer diagnostic interval, which is statistically significant (p<0.001). Prolongation of the diagnostic interval for more than 6 months has shown a decrement in the polymorbidity indicators and operational and anesthetic risk compared with DI≤6 months (p=0.001, p=0.039). Polymorbidity, in particular cardiovascular diseases decompensation, affected the indicators of operational and anesthetic risk on the ASA scale, which were significantly higher in the study group (p=0.039). High level of polymorbidity required a longer preoperative preparation in the studied group, which is statistically significant in comparison with the control group (p=0.018). Statistically significant differences in early postoperative complications rate in both groups were not revealed. 30 and 90 day mortality rates were similar in the studied and control groups (p=0.225, p=0.353). The study has also shown that diagnostic interval (DI) have no effect on the prevalence of II and III stages comparing with the control group (p=0.315).

Purpose: to develop a technique for therapeutic application of photoactivated photosensitizer «Radachlorin» to be included into the complextherapy of nosocomial pneumonia.Material and methods. Twelve patients with nosocomial pneumonia were taken in the trial. They were treated with a device having a nebulizer witha ring-shaped irradiator and diodes λ ≈ 660 nm for photoactivation of photosensitizer «Radachlorin» (manufactured by OOO «RADA-PHARMA»,Moscow, registration number LS-001868). The photosensitizer was developed according to the technical tasks provided by OOO «New SurgicalTechnologies» (Moscow, Russia). Radachlorin solution photolysis products were inhaled by the patients twice a day for 3 days in combinationwith the standard therapy when they were in ICU. Patients in the control group (n = 12) did not have any inhalations.Results and discussion. On day 3, the number of colony-forming units (CFU) of various pathogens found in swabs from the throat decreasedby 39.45 ± 3.17 % on average; C-reactive protein decreased by 42.38 ± 4.26 %; procalcitonin decreased by 51.83 ± 3.45 %, if to compareto baseline limits. At the same period in the control group, CFU in swabs increased in average by 17.28 ± 4.21 %; C-reactive protein increasedby 27.76 ± 3.52 %; procalcitonin increased by 30.15 ± 2.24 %. On day 10 in the main group, the number of CFU pathogens decreasedby 35.45 ± 3.32 %; C-reactive protein decreased by 72.15 ± 2.56 %; procalcitonin decreased by 55.56 ± 4.23 %, if to compare to baseline limits. On day 10 in the control group, CFU concentration remained elevated by 31.15 ± 2.56 %; C-reactive protein – by 65.32 ± 4.27; procalcitonin – by 30.21 ± 3.45 %, if to compare to baseline values. These findings indicate that the inflammatory process acquired a progressive form which demands switching to other curative modalities and more careful selection of antibiotics. The probability of random origin in statistical processing is p < 0.05. There were no undesirable side effects during procedures.Conclusion. Justified application of the described technique – inhalations of photolysis products of E 6 chloride derivatives – has an effective therapeutic impact at the course of nosocomial pneumonia. It seems promising to continue investigations on the described technique, namely, to search for the most effective ways of its application, to find out an optimal number and frequency of procedures under the control of general clinical and special methods of examination of the studied patients, since the data which have been obtained by the authors us are preliminary and should be supplemented with new findings.
