Machine Learning Classification of Pediatric Health Status Based on Cardiorespiratory Signals with Causal and Information Domain Features Applied-An Exploratory Study.

This study aimed to evaluate the accuracy of machine learning (ML) techniques in classifying pediatric individuals-cardiological patients, healthy participants, and athletes-based on cardiorespiratory features from short-term static measurements. It also examined the impact of cardiorespiratory coupling (CRC)-related features (from causal and information domains) on the modeling accuracy to identify a preferred cardiorespiratory feature set that could be further explored for specialized tasks, such as monitoring training progress or diagnosing health conditions. We utilized six self-prepared datasets that comprised various subsets of cardiorespiratory parameters and applied several ML algorithms to classify subjects into three distinct groups.

Features extraction from multi-spectral remote sensing images based on multi-threshold binarization.

In this paper, we propose a solution to resolve the limitation of deep CNN models in real-time applications. The proposed approach uses multi-threshold binarization over the whole multi-spectral remote sensing image to extract the vector of discriminative features for classification. We compare the classification accuracy and the training time of the proposed approach with ResNet and Ensemble CNN models.

QUAD SHOT - an effective hypofractionated palliative radiotherapy in patients with non-melanoma skin cancer. A single-institution experience.

Introduction: The primary approach for managing skin cancer involves surgery, although radical radiotherapy (RT) may be considered as an alternative option in cases where patients decline the treatment themselves or are not eligible for surgical intervention. Herein we assess single-institution material in terms of the use of hypofractionated QUAD SHOT RT in patients disqualified from surgery.

Material And Methods: Between December 2019 and December 2022, nine patients with locally advanced non-melanoma skin cancer were disqualified from surgery and as a result were treated at the Radom Oncology Centre, Poland.

Reproductive Results in Cancer Survivors after Fertility Sparing Management: The Need for the Standardization of Definitions.

In fertility-sparing management (FSM), two different issues can be distinguished: the risk of recurrence/death and the chance of childbearing. Survival is the principal outcome in oncology, and definitions of overall survival and progression-free survival are therefore well defined and widely accepted. The introduction of FSM to clinical practice was determined by the desire of young cancer patients to still have children.

Differential Effects of Overexpression of Wild Type and Kinase-Dead MELK in Fibroblasts and Keratinocytes, Potential Implications for Skin Wound Healing and Cancer.

Maternal embryonic leucine-zipper kinase (MELK) plays a significant role in cell cycle progression, mitosis, cell migration, cell renewal, gene expression, embryogenesis, proliferation, apoptosis, and spliceosome assembly. In addition, MELK is known to be overexpressed in multiple types of cancer and is associated with cancer proliferation. Tumorigenesis shares many similarities with wound healing, in which the rate of cell proliferation is a critical factor.

Mechanism of Chromium Separation and Concentration from Tannery Wastewater by Membrane Methods.

The article specifies conditions for a nanofiltration process employing a diafiltration method with a constant volume diafiltration (NF-CVD) for exhausted chromium tannery wastewater treatment and describes a mechanism of the examined process carried out for model wastewater. The authors prove that a decrease in salt concentration in the NF-CVD process is an important factor that enables effective concentration of chromium. Based on the proposed chromium separation and concentration mechanisms, it was found that this effect may be achieved by (1) limiting the formation of an ionic adsorption-polarization layer and (2) reducing the increase in the osmotic pressure caused by a change in the separation properties of the membrane.
