Over the time, the development of the digital design has increased dramatically and nowadays many different circuits and systems are designed for multiple purposes in short time lapses. However, this development has not been based only in the enhancement of the design tools, but also in the improvement of the verification tools, due to the outstanding role of the verification process that certifies the adequate performance and the fulfillment of the requirements. In the verification industry, robust methodologies such as the Universal Verification Methodology (UVM) are used, an example of this is [1], but they have not been implemented yet in countries such as Peru and they seem inconvenient for educational purposes. This research propose an alternative methodology for the verification process of designs at the industry scale with a modular structure that contributes to the development o...

In Mexico, a high percentage of young people experience symptoms of generalized anxiety, which are associated with difficulties in executive functions (EF). However, previous studies have shown inconsistent results, as they often rely solely on either objective or subjective measures. Therefore, this study focused on analyzing the relationship between generalized anxiety and EF using both a neuropsychological battery and a self-report questionnaire, in order to provide a more comprehensive understanding of cognitive functioning in adolescents. A quantitative, non-experimental, cross-sectional, correlational, and explanatory design was employed. The sample consisted of 96 adolescents between 12 and 15 years old from the state of Puebla, Mexico. A total of 10.41% of participants presented severe symptoms of generalized anxiety. A significant relationship was found between anxiety and one o...

Los dispositivos de radio tradicionales tienen una funcionalidad limitada que solo puede modificarse haciendo cambios en el hardware. En este sentido, cualquier mejora en la flexibilidad de un dispositivo de radio tradicional implica un aumento considerable en los costos de producción. Por otro lado, los sistemas de radio definidos por software (SDR) proporcionan una solución relativamente económica y efectiva, permitiendo múltiples funcionalidades que pueden mejorarse simplemente actualizando el software. El presente informe describe la implementación de cuatro sistemas SDR mediante el uso de una computadora portátil con el software GNURadio, una placa transmisora de RF y un dispositivo receptor de RF de bajo costo. Este trabajo se centra en el diseño de transmisores y receptores que pueden realizar técnicas de modulación para señal analógica (FM) y señal digital (QPSK).

Evolutionary Psychology (EP) supports the hypothesis of massive modularity (HMM), in which the mind is understood as a set of modules that fulfill a specific function to solve recurrent adaptive problems in our evolutionary adaptation environment. This set would be part of human nature and the objective of EP is to identify and explain them in distal terms. Its detractors argue that the modular conception is inconsistent with current theoretical and empirical knowledge. From the works of Carruthers and Crawford, I will defend that several of the criticisms against HMM assume the modular conception of Fodor (F-modules), who emphasizes the intentional aspect. However, EP highlights biological functionality, conceives modules as adaptive traits that evolve due to their effects on differential reproduction; that is, Darwinian modules (D-modules) and understands them as specialized informatio...

La glándula tiroides es una de las más importantes del sistema endocrino su principal función es la producción de hormonas tiroideas necesarias para satisfacer los requerimientos básicos de un organismo. Recientemente se ha demostrado que estas modulan la hemostasia, aumentando o disminuyendo el nivel o actividad de varios factores de coagulación. Diversos estudios indican que la disminución en los niveles plasmáticos de hormonas tiroideas, promueven un estado hipercoagulable e heperfibrinolítico, mientras que el aumento en de estas, conduce a un incremento en la coagulación y una disminución en la fibrinolísis. Objetivo: Determinar el nivel relación entre la actividad y las pruebas de hemostasia de los pacientes adultos mayores que acudieron al laboratorio Robert Ledley, ubicado en el distrito San Martin de Porres - Lima, durante el año 2023.

Low Density Parity Check codes presents itself as the dominant FEC code in terms of performance, having the nearest performance to the Shannon limit and proving its usefulness in the increasing range of applications and standards that already used it. Low power devices are not except of this rapid development, where it emerges the necessity of decoders of low power without totally sacrificing performance or resource usage. The present work details the devolopment of a LDPC decoder compliant with the DVB-S2 standard for digital television, motivated for its already established use in uplink and downlink satellite applications and its great performance at large code lengths. This research presents the study of the min-sum algorithm and the design of the elements that conform the core decoder, including both functional units (variable and check nodes), memory blocks and routing network.

One mechanism for estimating software quality is through the use of metrics, which are functions that evaluates certain characteristics of the product quality development. A software product can be evaluated from different points of view, and in that sense, the results of the evaluations are numeric vectors, which together describe the quality of the software. This research uses data from NASA's open access which undergo a process of reducing the dimensionality by principal component analysis (PCA), then applied three clustering techniques and evaluates the best grouping using Rand Index. Finally, the top clusters are tested with regression to find the metrics that are related to the error of the Software. The results suggest that groups consisting of software modules whose code source have a higher average of blank lines, show a higher density of error. This could be interpreted as an i...

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...

El Rn-222 se forma por la desintegración del Ra-226 y luego se desintegra en Po-218 y Po-214. Los iones de Po producidos se pueden colectar electrostáticamente usando una cámara polarizada con una fuente de alta tensión, luego el Po-218 decae a Po-214 emitiendo partículas α de 6.003 keV y posteriormente el Po-214 decae a Po-210 emitiendo partículas α de 7.687 keV. Al medir la concentración de estas partículas α en la cámara se puede determinar la concentración del radón en el aire de una forma indirecta. El prototipo que se ha desarrollando utiliza una cámara de medida de acero inoxidable de 2 L con un diodo PIN S3204-09 (Hamamatsu) de cuerpo desnudo como detector de partículas alfa. La cámara y el diodo están polarizados con una fuente de alta tensión (+500 V) para colectar los iones de Po y detectar las partículas alfas que se producen luego en la cadena de decaimie...
