Classification and selection of the main features for the identification of toxicity in Agaricus and Lepiota with machine learning algorithms.

The occurrence of fungi is cosmopolitan, and while some mushroom species are beneficial to human health, others can be toxic and cause illness problems. This study aimed to analyze the organoleptic, ecological, and morphological characteristics of a group of fungal specimens and identify the most significant features to develop models for fungal toxicity classification using genetic algorithms and LASSO regression. The results of the study indicated that odor, spore print color, and habitat were the most significant characteristics identified by the genetic algorithm GALGO. Meanwhile, odor, gill size, stalk shape, and twelve other features were the relevant characteristics identified by LASSO regression. The importance score of the odor variable was 99.99%, gill size obtained 73.7%, stalk shape scored 39.9%, and the remaining variables did not score higher than 18%. Logistic regression, k-nearest neighbor (KNN), and XG-Boost classification algorithms were used to develop models using the features selected by both GALGO and LASSO. The models were evaluated using sensitivity, specificity, and accuracy metrics. The models with the highest AUC values were XGBoost, with a maximum value of 0.99 using the features selected by LASSO, followed by KNN with a maximum value of 0.99. The GALGO selection resulted in a maximum AUC of 0.98 in KNN and XGBoost. The models developed in this study have the potential to aid in the accurate identification of toxic fungi, which can prevent health problems caused by their consumption.

Optimizing Clinical Diabetes Diagnosis through Generative Adversarial Networks: Evaluation and Validation.

The escalating prevalence of Type 2 Diabetes (T2D) represents a substantial burden on global healthcare systems, especially in regions such as Mexico. Existing diagnostic techniques, although effective, often require invasive procedures and labor-intensive efforts. The promise of artificial intelligence and data science for streamlining and enhancing T2D diagnosis is well-recognized; however, these advancements are frequently constrained by the limited availability of comprehensive patient datasets. To mitigate this challenge, the present study investigated the efficacy of Generative Adversarial Networks (GANs) for augmenting existing T2D patient data, with a focus on a Mexican cohort. The researchers utilized a dataset of 1019 Mexican nationals, divided into 499 non-diabetic controls and 520 diabetic cases. GANs were applied to create synthetic patient profiles, which were subsequently used to train a Random Forest (RF) classification model. The study's findings revealed a notable improvement in the model's diagnostic accuracy, validating the utility of GAN-based data augmentation in a clinical context. The results bear significant implications for enhancing the robustness and reliability of Machine Learning tools in T2D diagnosis and management, offering a pathway toward more timely and effective patient care.

Machine Learning Model Based on Lipidomic Profile Information to Predict Sudden Infant Death Syndrome.

Sudden infant death syndrome (SIDS) represents the leading cause of death in under one year of age in developing countries. Even in our century, its etiology is not clear, and there is no biomarker that is discriminative enough to predict the risk of suffering from it. Therefore, in this work, taking a public dataset on the lipidomic profile of babies who died from this syndrome compared to a control group, a univariate analysis was performed using the Mann-Whitney U test, with the aim of identifying the characteristics that enable discriminating between both groups. Those characteristics with a p-value less than or equal to 0.05 were taken; once these characteristics were obtained, classification models were implemented (random forests (RF), logistic regression (LR), support vector machine (SVM) and naive Bayes (NB)). We used seventy percent of the data for model training, subjecting it to a cross-validation (k = 5) and later submitting to validation in a blind test with 30% of the remaining data, which allows simulating the scenario in real life-that is, with an unknown population for the model. The model with the best performance was RF, since in the blind test, it obtained an AUC of 0.9, specificity of 1, and sensitivity of 0.8. The proposed model provides the basis for the construction of a SIDS risk prediction computer tool, which will contribute to prevention, and proposes lines of research to deal with this pathology.

Automatic Evaluation of Heart Condition According to the Sounds Emitted and Implementing Six Classification Methods.

The main cause of death in Mexico and the world is heart disease, and it will continue to lead the death rate in the next decade according to data from the World Health Organization (WHO) and the National Institute of Statistics and Geography (INEGI). Therefore, the objective of this work is to implement, compare and evaluate machine learning algorithms that are capable of classifying normal and abnormal heart sounds. Three different sounds were analyzed in this study; normal heart sounds, heart murmur sounds and extra systolic sounds, which were labeled as healthy sounds (normal sounds) and unhealthy sounds (murmur and extra systolic sounds). From these sounds, fifty-two features were calculated to create a numerical dataset; thirty-six statistical features, eight Linear Predictive Coding (LPC) coefficients and eight Cepstral Frequency-Mel Coefficients (MFCC). From this dataset two more were created; one normalized and one standardized. These datasets were analyzed with six classifiers: k-Nearest Neighbors, Naive Bayes, Decision Trees, Logistic Regression, Support Vector Machine and Artificial Neural Networks, all of them were evaluated with six metrics: accuracy, specificity, sensitivity, ROC curve, precision and F1-score, respectively. The performances of all the models were statistically significant, but the models that performed best for this problem were logistic regression for the standardized data set, with a specificity of 0.7500 and a ROC curve of 0.8405, logistic regression for the normalized data set, with a specificity of 0.7083 and a ROC curve of 0.8407, and Support Vector Machine with a lineal kernel for the non-normalized data; with a specificity of 0.6842 and a ROC curve of 0.7703. Both of these metrics are of utmost importance in evaluating the performance of computer-assisted diagnostic systems.

Comparison of Night, Day and 24 h Motor Activity Data for the Classification of Depressive Episodes.

Major Depression Disease has been increasing in the last few years, affecting around 7 percent of the world population, but nowadays techniques to diagnose it are outdated and inefficient. Motor activity data in the last decade is presented as a better way to diagnose, treat and monitor patients suffering from this illness, this is achieved through the use of machine learning algorithms. Disturbances in the circadian rhythm of mental illness patients increase the effectiveness of the data mining process. In this paper, a comparison of motor activity data from the night, day and full day is carried out through a data mining process using the Random Forest classifier to identified depressive and non-depressive episodes. Data from Depressjon dataset is split into three different subsets and 24 features in time and frequency domain are extracted to select the best model to be used in the classification of depression episodes. The results showed that the best dataset and model to realize the classification of depressive episodes is the night motor activity data with 99.37% of sensitivity and 99.91% of specificity.

¿Qué es la técnica en psicoanálisis? / What is technique in psychoanalysis?

El presente trabajo forma parte de la investigación de doctorado El concepto de acto analítico en psicoanálisis (Murillo, 2015a, 2015b, 2015c, 2015d). Interrogándonos sobre el concepto de acto analítico, quisiéramos contextualizar esta investigación en el marco de lo que la tradición psicoanalítica ha llamado la técnica. Desarrollamos para tal fin referencias a la técnica provenientes tanto del psicoanálisis como de la filosofía. Concluimos que la referencia a la técnica en psicoanálisis ha tenido muchos usos y sentidos entre los cuales cabe destacarse: el psicoanálisis como una técnica, la técnica como algo rígido o flexible, la técnica como algo que se refleja en consejos y escritos, y la técnica expresada como conceptos técnicos o el valor instrumental de todo concepto psicoanalítico.

The present paper forms part of the doctoral research The analytic act concept in psychoanalysis (Murillo, 2015a, 2015b, 2015c, 2015d). By asking about the concept of analytic act, we would like to contextualize this research within the framework of what the psychoanalytic tradition has called technique. We develop for this purpose references to the technique coming from psychoanalysis and philosophy. We conclude that the reference to technique in psychoanalysis has had many uses and meanings among which we must emphasize: psychoanalysis as a technique, technique as something rigid or flexible, technique as something reflected in advices and writings, and technique expressed as technical concepts or the instrumental value of any psychoanalytic concept.

La neurosis de clase / Class neurosis

El presente trabajo se inscribe en la investigación UBACyT El psicoanálisis y otras disciplinas: lazos contemporáneos y sus antecedentes en la obra de Freud y Lacan (Azaretto y Ross, 2014), cuyo problema general de investigación trata sobre la doble relación de diálogo que se establece entre el psicoanálisis con otras disciplinas, pero también otras disciplinas con el psicoanálisis, como recurso para la formalización de sus respectivos objetos de estudios y experiencias. En esta ocasión trataremos de una noción específica ­la neurosis de clase­ cuya delimitación se establece en la intersección y diálogo entre el psicoanálisis y la sociología. Para ello tomaremos referencias de S. Freud, S. Ferenczi y J. Lacan, provenientes del psicoanálisis; y de V. de Gaulejac, provenientes de la sociología.

This paper is part of the UBACyT research Psychoanalysis and other disciplines: contemporary ties and their antecedents in Freud and Lacan work (Azaretto and Ross, 2014), whose general research problem is about the double relationship of dialogue established between psychoanalysis with other disciplines, but also other disciplines with psychoanalysis, as a resource for the formalization of their respective objects of study and experiences. On this occasion we will deal with a specific notion ­class neurosis­ whose delimitation is established in the intersection and dialogue between psychoanalysis and sociology. For this we will take references of S. Freud, S. Ferenczi and J. Lacan, coming from psychoanalysis; and V. de Gaulejac, from sociology.

El concepto de técnica activa en los escritos técnicos de Sándor Ferenczi / The active technique concept in Sándor Ferenczi's technical writings

El presente trabajo forma parte de la investigación de doctorado El concepto de acto analítico en psicoanálisis (Murillo, 2015a, 2015b). La investigación se divide en dos grandes partes: en primer lugar el análisis del concepto de acto analítico en la obra de J. Lacan; y en segundo lugar el análisis de diversos conceptos de la historia del psicoanálisis que constituyen antecedentes o aproximaciones al acto analítico desde otros marcos teóricos o lenguajes del psicoanálisis, y con los cuales Lacan dialoga y debate. En esta ocasión nos centraremos en un autor y un concepto en particular, el concepto de "técnica activa" de Sándor Ferenczi.

The present work si part of the doctoral research The analytical act concept in psychoanalisis (Murillo, 2015a, 2015b). There search recognize two parts: irst the analysis of analytical act concept in Lacan work; second, the analysis of different concepts of the psychoanalysis history considered as antecedent of the analytic act concept, and which Lacan dialogues and argue. In this time we will focus in one author and particular concept, the "active technique" concept of Sándor Ferenczi.

El concepto de fin de análisis y el problema de la puerta / The end of the analysis concept and the door problem

El presente trabajo forma parte de la investigación de doctorado "El acto analítico en la obra de J. Lacan"(Murillo, 2015a, 2015b). Nos interrogamos por el concepto de fin de análisis desde la perspectiva de un problema de producción de salidas a las situaciones o encrucijadas que involucran la posición del sujeto. Concluimos que el concepto de fin de análisis no es un concepto temporal sino espacial, relativo a las salidas que un análisis va produciendo para un sujeto, independientemente de la duración, la continuación o la conclusión del análisis.

This paper is part of the doctoral research "The analytical act in J. Lacan work" (Murillo, 2015a, 2015b). We interrogate for the end of analysis concept in the perspective of a problem of exit production to the situations which involves the subject position. We conclude that the end of analysis concept is not a temporal concept but a spacial concept, related to the exits productions of the analysis, independently of the duration, the continuation or the conclusion of the analysis.

Effects of Candida norvegensis Live Cells on In vitro Oat Straw Rumen Fermentation.

This study evaluated the effect of Candida norvegensis (C. norvegensis) viable yeast culture on in vitro ruminal fermentation of oat straw. Ruminal fluid was mixed with buffer solution (1:2) and anaerobically incubated with or without yeast at 39°C for 0, 4, 8, 16, and 24 h. A fully randomized design was used. There was a decrease in lactic acid (quadratic, p = 0.01), pH, (quadratic, p = 0.02), and yeasts counts (linear, p<0.01) across fermentation times. However, in vitro dry matter disappearance (IVDMD) and ammonia-N increased across fermentation times (quadratic; p<0.01 and p<0.02, respectively). Addition of yeast cells caused a decrease in pH values compared over all fermentation times (p<0.01), and lactic acid decreased at 12 h (p = 0.05). Meanwhile, yeast counts increased (p = 0.01) at 12 h. C. norvegensis increased ammonia-N at 4, 8, 12, and 24 h (p<0.01), and IVDMD of oat straw increased at 8, 12, and 24 h (p<0.01) of fermentation. Yeast cells increased acetate (p<0.01), propionate (p<0.03), and butyrate (p<0.03) at 8 h, while valeriate and isovaleriate increased at 8, 12, and 24 h (p<0.01). The yeast did not affect cellulolytic bacteria (p = 0.05), but cellulolytic fungi increased at 4 and 8 h (p<0.01), whereas production of methane decreased (p<0.01) at 8 h. It is concluded that addition of C. norvegensis to in vitro oat straw fermentation increased ruminal fermentation parameters as well as microbial growth with reduction of methane production. Additionally, yeast inoculum also improved IVDMD.

¿Qué es el acto analítico? / What is the analytical act?

Este artículo forma parte de una investigación más general sobre el concepto de acto analítico en la obra de Lacan. La investigación se deriva de otras dos. El proyecto de Investigación UBACyT (Azaretto y Ros, 2014-2017) El Psicoanálisis y otras disciplinas: lazos contemporáneos y sus antecedentes en la obra de Freud y Lacan. Y la investigación de maestría (Murillo, 2015) La hipótesis de los tres registros. Sujeto, metapsicología y formalización en psicoanálisis. Se plantea la pregunta sobre el acto analítico como un problema de especificidad, significación y vacilación del concepto: ¿Qué es el acto analítico? ¿Qué significa que sea un acto? ¿Cómo se incorpora el concepto en el corpus más general de conceptos lacanianos? Para el tratamiento de estas preguntas se analizan referencias de los seminarios 14 y 15 de Lacan.

This paper is part of a larger research about analytic act concept in Lacan work. It derives from other two researches. The UBACyT research proyect (Azaretto and Ros, 2014-2017) Psychoanalysis and other disciplines: contemporary ties and their antecedents in Freud and Lacan work. And the master research (Murillo, 2015) The three registers hypothesis. Subject, metapsychology and formaliza-tion in psychoanalysis. We formulate the analytic act question as a specificity, meaning and hesitation problem: What is the analytic act? What does it means, to be an act? How the concept is incorporated in the wider corpus of lacanian concepts? For the treatment of these questions we analyzed references from Lacan seminars 14 and 15.

Acceptability of smartphone technology to interrupt sedentary time in adults with diabetes.

Breaking up sitting time with light- or moderate-intensity physical activity may help to alleviate some negative health effects of sedentary behavior, but few studies have examined ways to effectively intervene. This feasibility study examined the acceptability of a new technology (NEAT!) developed to interrupt prolonged bouts (≥20 min) of sedentary time among adults with type 2 diabetes. Eight of nine participants completed a 1-month intervention and agreed that NEAT! made them more conscious of sitting time. Most participants (87.5 %) expressed a desire to use NEAT! in the future. Sedentary time decreased by 8.1 ± 4.5 %, and light physical activity increased by 7.9 ± 5.5 % over the 1-month period. The results suggest that NEAT! is an acceptable technology to intervene on sedentary time among adults with type 2 diabetes. Future studies are needed to examine the use of the technology among larger samples and determine its effects on glucose and insulin levels.

Georg Groddeck: transferencia y resistencia en psicoanálisis / Georg Groddeck: transference and resistance in psychoanalysis

Este trabajo forma parte de la investigación de maestría La hipótesis de los tres registros. Sujeto, metapsicología y formalización en psicoanálisis (Murillo, 2010, 2011a, 2011b, 2011c, 2012a, 2012b, 2013a, 2013b) y la investigación UBACyT Lógicas de producción en el campo de investigaciones en psicoanálisis (Azaretto y Ros, 2011). El objetivo del siguiente escrito es analizar el capítulo que corresponde a Georg Groddeck en el desarrollo de la hipótesis de los tres registros, en particular en relación al concepto del ello como crítica general de la subjetividad, del yo y del dualismo psíquico-somático. Concluimos que si bien no sabemos acerca de la lectura por parte de Lacan de la obra de Groddeck, la obra de ambos autores confluye singularmente hacia una crítica común respecto del concepto de sujeto y del estatuto de lo simbólico en su fundamento.

This paper is part of two investigations: The three orders hypothesis. Subject, metapsychology and formalization in psychoanalysis (Murillo, 2010, 2011a, 2011b, 2011c, 2012a, 2012b, 2013a, 2013b) and Logic of productions in psychoanalysis field research (Azaretto y Ros, 2011). The objective of this paper is to analyze the place and function of Georg Groddeck ideas in the development of the three orders hypothesis, particularly related to the It concept, as a general critic of subjectivity, ego and psychic-somatic dualism. We conclude that although we don/'t know if Lacan was or not a reader of Groddeck, both authors ideas converge in a singular way in a critic of subject concept, ego concept and the postulation of the symbol as a fundament.

El significante no es un arquetipo / The signifier is not an archetype

Este artículo forma parte de la investigación de maestría La hipótesis de los tres registros.

El objetivo de este artículo es desarrollar la referencia de Jung en el desarrollo de la hipótesis de lo simbólico, o de la teoría del simbolismo. Se concluye que el significante no es un arquetipo, sin embargo hay aspectos del desarrollo de la teoría del significante que retoman aspectos ya desarrollados en la teoría del arquetipo...

La construcción del tiempo en la investigación / The construction of time in scientific research

El trabajo se propone problematizar la noción de temporalidad o tiempo que se pone en juego actualmente en la metodología de la investigación. Y en particular en la construcción o diseño metodológico del objeto de estudio de la investigación, a partir de la noción de matriz de datos o sistema de matrices de datos. Los desarrollos se inscriben en antecedentes en la temática desarrollados por Juan Samaja y Roxana Ynoub respecto a este tema. Para abordar este problema se desarrollarán algunas referencias clásicas de la metodología de la ciencia y se intentará aportar a este problema nociones provenientes de las categorías lógicas de relación de I. Kant, y de la noción de trama de Aristóteles. Finalmente se analiza el tratamiento propuesto a la luz de un ejemplo paradigmático tomado de S. Freud.
