Computed tomography (CT) is a breakthrough technology used in medicine for diagnostic diseases. The same technique is used in other areas, such as aerospace chemistry, Radio astronomy, etc. The main objective of the CT is to reconstruct the internal part of an object without having to open it as a non-destructive test. To achieve this purpose, the CT uses the attention that X-rays undergo through this object with the information, the inner part of the object is reconstructed, that is to say the CT is an inverse problem.In this article uses the Fourier transform for the reconstruction of the internal part, for it is directly part of a continuous model, representing the density at the point (x, y) of a section, with a function p = p(x, y); and even though p is not required to be continuous, the Fourier method is more efficient and a better, more regular result is obtained p.

From the covariant formulation of radiation intensity of Hartemann-Kerman model entirely constructed in the classical electrodynamics scenario, a formulation of coherent states has been obtained in an explicit manner represented by the infinite sum of integer-order Bessel functions. Both linear and nonlinear Compton scattering are included, suggesting that Compton processes can be perceived as coherent states of lightmatter interaction.

From a mathematical model given by the integral Im,n=∫Pm(x)G(x)Jn(x)dx where Pm(x) a polynomial function, G(x) a Gaussian function, and Jn(x) is the integer-order Bessel function, we have performed simulations to evaluate the possible scenario of outbreak of Zika virus (ZIKV) in a big city. Our study is motivated from the outbreaks in Brazil (2007). We have assumed a list of probabilities which are connected to the number of cases in-risk which is changing in time. Also, the intervention is defined as the fraction ΔIm,n and it is selected by the Monte Carlo step. Simulations takes into account the rapid intervention that means the transfer of those identified (e.g. pregnant women) to save and clean areas away from the mosquitoes Aedes.

Spermidine is a polyamine compound found in fruits, vegetables, meats and milk products. It is also known for its role as a modulator of functions for DNA, RNA, nucleotide triphosphates and proteins. Some recent experimental studies have shown that it has an inhibitory function on the protein related to the pathogenesis of myotonic dystrophy type 1 (MBNL‐1), providing some hope in relation to this disease presently without cure. However these studies have not provided sufficient information to explain its inhibitory role. In the present work, the existing interaction between spermidine and the MBNL‐1 protein has been confirmed by computational chemistry. The quantum mechanics analysis was carried out with the CAM‐B3LYP density functional, using a TZVP basis set. For the molecular mechanics, the OPLS‐AA force field was used, followed immediately by the solvation of the MBNL‐1 pr...

Inertial kinetics and kinematics have substantial influences on human biomechanical function. A new algorithm for Inertial Measurement Unit (IMU)-based motion tracking is presented in this work. The primary aims of this paper are to combine recent developments in improved biosensor technology with mainstream motion-tracking hardware to measure the overall performance of human movement based on joint axis-angle representations of limb rotation. This work describes an alternative approach to representing three-dimensional rotations using a normalized vector around which an identified joint angle defines the overall rotation, rather than a traditional Euler angle approach. Furthermore, IMUs allow for the direct measurement of joint angular velocities, offering the opportunity to increase the accuracy of instantaneous axis of rotation estimations. Although the axis-angle representation requi...

Infectious bursal disease is a pathology of viral origin that affects poultry, causing a high mortality rate. Existing vaccines face the problem of the appearance of new strains, so searches are made for molecules with potential binding affinity to viral proteins. Withania somnifera extract is involved in the replication of infectious bursitis virus, but the possible mechanism of action is not well understood. The aim of this study was to identify, through in silico methods, the phytoconstituents of W. somnifera with binding affinity to the active site of viral protein 1 (VP1) of infectious bursal disease virus. Molecular docking assays were performed between VP1 and 27 phytoconstituents described in W. somnifera. The binding energy data obtained were analysed with the Kruskal-Wallis test and Dunn’s test (p<0.05). The results showed that the compounds somniferin, withanolide A, with...

The video game industry has undergone one of the most significant transformations in recent times. This is reflected not only in the economic aspect but also in the increasing number of players who want to explore and interact in the world of video games in recent years. As for the Real-Time Strategy (RTS) genre, which reached its peak in the early 2000s, it did not continue to see the same trend in game development, and the population of active players has been declining [1]. The primary reason for this continuous decline is the competition from games in other genres such as First Person Shooter (FPS), Multiplayer Online Battle Arena (MOBA), and other genres with attractive characteristics that set them apart. In response to this, a solution is offered, which involves the development of a multiplayer RTS video game for Windows operating systems (PC), with the aim of generating greater i...

The task of elaborating accurate test suites for program testing can be an extensive computational work. Mutation testing is not immune to the problem of being a computational and time-consuming task so that it has found relief in the use of heuristic techniques. The use of Genetic Algorithms in mutation testing has proved to be useful for probing test suites, but it has mainly been enclosed only in the field of imperative programming paradigms. Therefore, we decided to test the feasibility of using Genetic Algorithms for performing mutation testing in functional programming environments. We tested our proposal by making a graph representations of four different functional programs and applied a Genetic Algorithm to generate a population of mutant programs. We found that it is possible to obtain a set of mutants that could find flaws in test suites in functional programming languages. Ad...

We used computational simulation inside a teleconsult scheme to predict the levels of diabetes progress of a sample of type-2 diabetes adult patients. Concretely, we have used computational algorithms to estimate the fraction of patients which would acquire diabetes complications such as necrosis, nephropathy and unexpected cardiovascular events. For this end, we have constructed a general function G which gives account of the behavior of glucose in time, but it is depending of up to 4 free parameters representing in somewhat: Diet, pharmacology, attitude of patient against the progress of disease, and a random number by the which it might be consistent with the binge eating disorder. From the results of this paper around 5±1 patients might increase their probabilities to pass to the subsequent diabetes such diabetic nephropathy.
