Supramolecular hydrogels based on chitosan and monoaldehydes are biomaterials with high potential for a multitude of bioapplications. This is due to the proper choice monoaldehyde that can tune hydrogel properties specific practices. In this conceptual framework, present paper deals investigation as bioabsorbable wound dressing. To aim, was cross-linked 2-formylphenylboronic acid yield antimicrobial activity. FTIR, NMR, POM procedures have characterized from structural supramolecular point...

In this paper, we propose to quantitatively compare the loss of human lung health under influence illness with COVID-19, based on fractal-analysis interpretation chest-pulmonary CT pictures, in case small datasets, which are usually encountered medical applications. The fractal analysis characteristics, such as dimension and lacunarity measured values, have been utilized an effective advisor pulmonary picture texture.

In this study, we will discuss the engineering construction of a special sixth generation (6G) antenna, based on fractal called Minkowski’s loop. The antenna has shape known fractal, set at four iterations, to obtain maximum performance. frequency bands for which 6G was designed in current paper are 170 GHz 260 (WR-4) and 110 (WR-6), respectively. three resonant frequencies, optimally used, equal 140 (WR-6) first, 182 second 191 third. For these frequencies electromagnetic behaviors antennas...

Multiple sclerosis (MS) is an inveterate phlogistic situation characterized by focal and vaguely diffusive de-myelination neurodegeneration, in the sphere of central nervous system (CNS). The brain's chronic inflammatory reaction includes astrocyte stimulation microglial motivation, as well macrophages marginal conscription. This lasting serious soreness brain connected with neurodegeneration period disability advance.The present study considering two main purposes follows. Primarily, to...

Abstract The projection of fifth‐generation (5G) fractal antennas and their advantageous geometry are examined. fact that fractal‐shaped based on Koch Snowflake suitable for higher frequencies was shown above all. By the instrumentality this technology, which aims to serve a large number subscribers by implementing revolutionary devices (e.g. Massive MIMO, beam‐forming, high‐performance processors, etc.), it is possible obtain multiple facilities. Fractal geometrics forms have been made...

This article presents two algorithms developed based on different techniques, from clusterization theory, namely k-means clustering technique and Fuzzy C-means technique, respectively. In this context, the study offers a sustained comparison of in order to properly choose one them, depending image be analyzed solution that is desired. Algorithms are used processing, respectively as application processing techniques brain computed tomography analysis. There were also compared results obtained...

Four medicament delivery formulations based on 5-fluorouracil in a chitosan substantial matrix were realized situ via 3,7-dimethyl-2,6-octadienal element hydrogelation. Representative samples of the final compounds investigated from an analytic, constitutional, and morphological viewpoint Fourier transform infrared (FTIR) spectroscopy scanning electron microscopy (SEM). The SEM images concordance with fractal analysis, dimensions lacunarity computed. developed mathematical multifractal model...

The present article describes novel massive materials (in the solid phase) based on TEGylated phenothiazine and chitosan that possess great capability to recover mercury ions from constituent aqueous solutions. These were produced by hydrogelation accompanied formyl subsidiary item of phenothiazine, attended lyophilization. delineation structure description obtained material or supramolecular assembly realized FTIR (Fourier transform infrared) spectroscopy, X-ray diffraction, POM (Polarized...

This paper introduces an AI model designed for the diagnosis and monitoring of SARS-CoV-2 virus. The present artificial intelligence (AI) founded on machine learning concept was created identification/recognition, keeping under observation, prediction a patient’s clinical evaluation infected with CoV-2 deep (DL)-initiated process (an subset) is punctually prepared to identify patterns provide automated information healthcare professionals. algorithm based fractal analysis CT chest images,...

In this study, one method of using antennas based on fractals to cover few kinds public protection and disaster relief (PPDR) communications was presented. Dedicated antenna forms, necessary for design by 5G implementation, were enhanced suit the requirements specific applications. Employing fractal-shaped have allowed us accomplish all these actions, which request compact, conformal, broadband high performance devices. Antennas derived from Koch’s curve are studied. order implement PPDR in...

A method of analyzing human pulmonary X-rays using a few software procedures to process the images will be presented. Photographs lungs were investigated and arteries illustrated, successfully extracting shadows due ribs lung itself through an advanced algorithm. This paper presents solution for processing interpretation X-ray in order deploy better fractal analysis, find out dimension lacunarity network.

Publicly available speech datasets for Romanian are still scarce, being far from enough obtaining state-of-the-art performance with modern deep neural networks. As a response to this issue, during the development of an internal automatic recognition system national emergency call center, we have created Speech Alert Corpus, new corpus that was obtained by crowd-sourcing reading sentences in our institution. This paper describes data acquisition process, several statistics about resulted and...
