“Los jesuitas no están conmigo pues ellos están contra mí”: el anti-jesuitismo en la Buenos Aires rosista después de la restauración de la Compañía de Jesús
Authors: Perrone Nicolás Hernán
Published: September 2023

El objetivo de este trabajo será estudiar las expresiones y ataques anti-jesuíticos que se desenvolvieron entre 1836 y 1843 en la Buenos Aires rosista luego de la restauración de la Compañía de Jesús en esa provincia. La fuente principal para este estudio será la Historia secreta de la supresión de la Compañía de Jesús en Buenos Aires escrita por Mariano Berdugo, jesuita español y superior de la misión porteña. A partir de la reconstrucción parcial de los hechos realizada por Berdugo buscaremos comprender si los ataques por él recogidos fueron una construcción retórica para justificar sus actos durante su gobierno de la comunidad o si fueron adaptaciones locales de mitos anti-jesuíticos de larga duración. Comprender las bases y los motivos de los ataques recibidos por los ignacianos será de utilidad para comprender el proceso de inserción local de los mismos el contexto del proceso global de restauración de la Compañía.
La representación de la prostitución en las Bellas Artes en Chile: un análisis histórico de “El mercado de blancas” (c.1903) y “El baile de las enanas” (1936)
Authors: Gálvez Comandini Ana Carolina , Sosa Vota María Silvina
Published: September 2023

Este artículo tiene como objetivo analizar a través de dos obras pictóricas nacionales pioneras que abordaron el tema del comercio sexual femenino, la relación o vínculo entre las expresiones artísticas de las Bellas Artes y el mundo de la prostitución en Chile durante la primera mitad del siglo XX. Se sostiene que las tensiones en torno a las Bellas Artes y las representaciones de la marginalidad asentada en las ciudades producto de la modernización urbana, representan un conflicto no resuelto hasta bien entrado el siglo XX, pues en Chile el paradigma de “lo bello” estaba vinculado al modelo conservador y neoclasicista europeo, por lo que las temáticas del arrabal urbano fueron expulsadas a los márgenes de la academia. En este artículo expresamos, cómo los artistas que se atrevieron a incursionar tempranamente en la temática de la prostitución fueron rechazados o ignorados, debiendo cambiar te tema de sus obras, o recibiendo un reconocimiento póstumo.
Érase una vez en Hollywood. La aventura de Walt Disney y el I Seminario de educación visual
Authors: Zamorano-Rojas Alma Delia
Published: September 2023

En 1944, Walt Disney emprendió el proyecto Reading for the Americas, ambicioso plan para la alfabetización de América Latina impulsado por la Oficina del Coordinador de Asuntos Inter Americanos (OCAIA), que intentaba reforzar la idea de la buena voluntad y vecindad pregonada por Estados Unidos en medio de la guerra.

Este artículo tiene como objetivo documentar un capítulo casi desconocido en esta aventura: la organización del I Seminario de educación visual, el cual fue diseñado desde los estudios Disney en Hollywood, esbozado con base en la experiencia mexicana y precursor para alfabetizar en principio a adultos de toda América Latina por medio de la utilización del cine de 16 mm.

A través de la recopilación de archivos especializados en México y Estados Unidos, y fundamentado en un seguimiento cronológico de las actividades que se desarrollaron en dicho seminario, dos paradigmas planteados en esta reunión se convirtieron en detonantes del fracaso del proyecto de Disney y de su puesta en práctica en el continente americano: las metodologías de enseñanza y la proyección sin la debida comprensión de lo que en realidad era América Latina, aunado a la propaganda política que se intentó filtrar en todos los ámbitos sociales por todos los medios posibles.
El avance de la reacción en la UNCuyo: la misión Ivanissevich (1974-1976)
Authors: Murri María Lourdes
Published: September 2023

El presente trabajo se propone realizar una aproximación al pasado reciente en la provincia de Mendoza tomando como unidad de observación la Universidad Nacional de Cuyo y las dinámicas internas en dicha institución durante la llamada “misión Ivanissevich” ocurrida a nivel nacional entre 1974 y 1976, para realizar una limpieza ideológica dentro de las universidades.

 Entendemos que, en la UNCuyo, en el marco de la misión Ivanissevich, tuvo lugar una “depuración” ideológica y de personas que se orientó a la eliminación de un sector que había sido impulsor y partícipe de la reforma de 1973-1974.  Este reordenamiento, realizado por medios legales e ilegales y clandestinos, resultó funcional a los grupos académicos de derecha que consolidaron su poder en ese contexto.

Revisaremos de manera diferencial cómo operaron los mecanismos de represión hacia las autoridades y docentes de la universidad como así también hacia el movimiento estudiantil. Consideramos necesario detenernos en este periodo dada la escasez de estudios que abordan este proceso en la UNCuyo y porque resulta central para comprender la escalada posterior de terror que se desató a partir de la última dictadura militar.

Impact of steroid and lidocaine injection in the sacroiliac joint in axial spondyloarthritis patients: a randomized controlled trial
Authors: Elsaman Ahmed , Khalifa Asmaa , Mahrous Sohir , Ibraheem Medhat , Ali Fatma , Radwan Ahmed
Published: September 2023

Background: The value of steroid and lidocaine injection of the sacroiliac joint in axial spondyloarthritis patients on magnetic resonance imaging scores and clinical disease outcome measures is not yet well assessed.

Patient and methods: Participants were randomly assigned into two groups; Group I received unilateral ultrasound-guided sacroiliac joint injection with .5% lidocaine hydrochloride mixed with triamcinolone. At the same time, group II received subcutaneous saline injection. All participants fulfilled the ASAS criteria for axial SpA and all had bone marrow edema of at least one sacroiliac joint at baseline. Outcomes measures were: Visual Analogue Scale (VAS), Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath Ankylosing Spondylitis Functional Index (BASFI), and Spondyloarthritis Research Consortium of Canada (SPARCC) scores. Participants were assessed at baseline (before and after sacroiliac joint injection) and after three months. This clinical trial was registered on clinicaltrials.gov under the number NCT04895228.

Results: In this study, a total of 61 participants were registered. There was a significant difference between both groups regarding pain, spine mobility, SPARCC, and ASDAS scores in favor of group I. Spine mobility showed the earliest improvement, followed by pain whilst SPARCC, and ASDAS scores showed improvement after three months. Higher disease activity, younger age, and shorter disease duration were all associated with better outcomes. Bilateral hip involvement was a predictor of poor response.

Conclusion: Sacroiliac joint injection of lidocaine and triamcinolone in axial SpA patients is a cost-effective and practical technique for controlling pain, improving function, disease activity scores, and bone marrow edema with acceptable complications and relatively sustained effect.
Investigation of the Relationship between PTPN22 Polymorphisms and Lung Sarcoidosis: A cross sectional study
Authors: Kaymaz Serdar , Kavas M. , Demiray A. , Karasu U. , Çob V.
Published: September 2023

Objective: Sarcoidosis is a systemic granulomatous disease with an unknown etiology characterized by noncaseating granuloma formation. It most often affects the lungs. Protein tyrosine phosphatase non-receptor 22 (PTPN22) is a gene that acts as a negative regulator of T-cell activation. Polymorphisms of this gene are associated with multiple human autoimmune diseases. The aim of this study was to assess the relationship between PTPN22 polymorphisms and lung sarcoidosis in a selected population.

Methods: The study included 64 patients with lung sarcoidosis and 30 healthy controls. Patients were genotyped to determine two single nucleotide polymorphisms (SNPs) using the polymerase chain reaction (PCR) method. Hardy–Weinberg equilibrium (HWE), an important tool for detecting genotyping errors, was tested. Direct counting was used to estimate genotype frequencies. Logistic regression analysis was performed to compare allele and genotype frequencies between the patient and control groups.

Results: The results of the study showed no correlation between lung sarcoidosis and the tested two SNPs of the PTPN22 gene (rs2488457, rs1310182) (p>0.05). The categorization analysis according to the clinical features, laboratory, and radiographic characteristics showed no correlation between the tested polymorphism of PTPN22 and these characteristics (p>0.05). 

Conclusion: The present study demonstrated that the studied two SNPs of the PTPN22 gene (rs2488457, rs1310182) were not correlated with lung sarcoidosis, suggesting that it might be different from other classic autoimmune disorders. There is a need for more studies to verify these results concerning lung sarcoidosis in other ethnic origins.

Published: September 2023

The infectious disease COVID-19, caused by the SARS-CoV-2 virus, is characterized by a wide range of clinical manifestations (pulmonary and extrapulmonary) and in some cases with post-infectious manifestations in persons who survived the infection. The vascular tropism of SARS-CoV-2 is the basis for the interest in using nailfold capillaroscopy to assess the microcirculation in children and adults who have recovered from COVID-19. Most often, non-specific changes are observed, without certain manifestations of microangiopathy and without a specific combination of microvascular findings, on the basis of which to define a specific capillaroscopic picture of the "COVID - 19" type. The possibility that capillaroscopy in combination with other findings can be used for personalized approach and determination of prognosis in patients with post-COVID syndrome needs further studies.

Published: September 2023

Abstract: SAPHO syndrome is characterized with a set of symptoms including skin lesions, osteoarticular manifestations like aseptic osteitis (of the anterior chest wall or other skeletal sites), peripheral synovitis. Due to the lack of randomized clinical trials and low prevalence of the condition, there are no established treatment guidelines for SAPHO syndrome. Here, we report a clinical case of SAPHO syndrome with osteitis of the sternum and palmoplantar pustulosis successfully treated with zoledronic acid and hydroxychloroquine.
Estudio de la participación de dos factores de transcripción WRKY de tomate en la defensa contra Pseudomonas syringae
Authors:   , Ramos Romina Nair
Published: September 2023

Utilizando datos previos disponibles de RNA-seq, identificamos dos genes WRKY de tomate cuya expresión se induce durante la respuesta inmune temprana PTI y la ETI asociada a Pto/Prf. Nuestra caracterización del silenciamiento de los genes ortólogos en N. benthamiana indicó que contribuyen a la ETI activada por elicitores de diversos patógenos, incluidas bacterias, virus, oomicetes y nematodos. La tecnología CRISPR-Cas9 nos permitió generar tres líneas de tomate knock out para los SlWRKYs de interés. Utilizando estas líneas, pudimos determinar que, tanto SlWRKY22 como SlWRKY25, son reguladores positivos de las respuestas PTI y ETI en tomate. Además, participan en la activación de defensas apoplásica y mediada por estomas, en este último caso regulando el cierre de los mismos. Ambos FT están localizados en el núcleo pero, en nuestras condiciones, no parecen interactuar físicamente. Los experimentos revelaron un mecanismo de acción mediante el cual SlWRKY22 regula la expresión del gen SlWRKY25 y que permite explicar la falta de redundancia funcional observada entre estos dos FT en la inmunidad del tomate. Finalmente, realizando un análisis de co-regulación y ensayos histoquímicos para GUS se encontró a NRG1 como un gen candidato a ser regulado por SlWRKY22 y SlWRKY25.
The Tale of Mamai’s Battle, The Tale of the Destruction of Ryazan by Batu Khan, and the Nikon Chronicle: the Beginning of the Russian Historical Fiction
Authors: Горский А.А.
Published: September 2023

В статье изучается вопрос о времени появления прямого художественного вымысла в древнерусских произведениях на историческую тему. Рассмотрены три памятника, созданные в один исторический период — в начале XVI в.: «Сказание о Мамаевом побоище» — наиболее пространное произведение из повествующих о Куликовской битве 1380 г., «Повесть о разорении Рязани Батыем», описывающая монгольское нашествие на Рязанскую землю в 1237 г., и Никоновская летопись — летописный свод. Делается вывод, что все они содержат полностью вымышленные эпизоды и сюжеты, из чего следует, что художественный вымысел в историческом повествовании распространяется именно в XVI столетии. Воспринимать «Повесть о разорении Рязани Батыем» и «Сказание о Мамаевом побоище» как источники для изучения нашествия монголов и битвы на Куликовом поле неправомерно. Эти произведения ценны именно как памятники художественной литературы, а не как фиксация реальных событий. Никоновская летопись внесла вымысел и в жанр летописания. Прослеженные явления вполне типичны для литературы начала европейского Нового времени.

The article highlights the moments when a fiction takes place in Old Russian sources on History. Examined are three monuments created at the same historical period — at the beginning of the 16th century: the Tale of Mamai’s Battle — one of the most vague narratives on the 1380 Battle of Kulikovo, the Tale of the Destruction of Ryazan by Batu Khan, which talks about the Mongolian Invasion of the Ryazan lands of 1237, and the Nikon Chronicle. A conclusion has been made that all the texts include purely fictitious episodes, which show that artistic fiction in historic narratives is spread in the 16th century. Taking the Tale of Mamai’s Battle and the Tale of the Destruction of Ryazan by Batu Khan as sources for research on the Mongol Invasion and the Battle of Kulikovo is inappropriate. Those works are voluble monuments of fiction literature, but do not depict real historical events. The Nikon Chronicle brought fiction into the chronicle genre. Traced events are typical for literature of the beginning of the modern European history.

These are important factors that must be considered and asked by TB officers at health facilities before the patient undergoes an examination of suspected samples and information to provide appropriate medical therapy to TB patients in health facilities.
Alexandre Kojève – Filozoficzny jakobin czy nowoczesny bonapartysta?
Authors: Winczewski Damian
Published: September 2023

Kojève is considered by many to be a Marxist thinker whose interpretation of Hegelianism was said to be similar to the twentieth-century ‘totalitarian’ ideologies. Historical research on his political thought has preserved his image as a ‘philosophical Jacobin’, who had an affirmative stance toward political violence and was an apologist for revolutionary activity, the ultimate goal of which was to be ‘the end of history’. The article aims to present an alternative narrative based on new research and sources that show that his thought is much more nuanced. Firstly, it is claimed that the context of his work should be found primarily in Russian religious philosophy and relations with Russian intellectuals in exile. Secondly, the infl uence of geopolitical changes in the first half of the twentieth century on the evolution of his political concepts is emphasised. Thirdly, his critical attitude to revolutionary theories is discussed. Finally, the article concludes with a presentation of the views of ‘mature’ Kojève as one of the creators of the vision of modern European universalism based on a specific ideal of justice and the desire for a lasting peace ending the post-Enlightenment chaos full of brutal wars and revolutions.
Ludzie i metody. Rozbijanie podziemia niepodległościowego w Lubartowskiem (lipiec 1944 – kwiecień 1947)
Authors: Poleszak Sławomir
Published: September 2023

The Lubartów district was one of the poorest areas of the Lublin province; nevertheless, strong structures of the independence underground subordinated and then reporting to the legitimate Polish government in exile were active in its area. The main crackdown on the underground occurred between August 1944 and April 1947. In the first year after the communists took power, the Soviets and the structures of the repression apparatus created in Lubartów took the main role in smashing the local underground. Its Polish officers mostly came from rural backgrounds and were poorly educated and trained. Ethnically, they were mostly Poles. However, at the District Public Security Office (PUBP) in Lubartów, two of the first three PUBP managers were Ukrainians by origin. The section that was responsible for fighting the underground was initially headed by a Jew, who was succeeded by a Ukrainian. Despite their low level of education and training, it was security office (UB) officers who were victorious in the crackdown on the local underground. Soviet assistance, violence and lawlessness guaranteed success.
Dzieje Muzeum Kultury Łemkowskiej w Zyndranowej i jego rola w zachowaniu i propagowaniu kultury łemkowskiej
Authors: Drozd Roman
Published: September 2023

After World War II, the Lemko population was deported from their homeland to Poland by communist authorities. Material traces of their culture were left behind exposed to intentional and unintentional devastation. Some Lemko activists could not agree with the state of affairs and decided to prevent it. To this end, they set up a museum in an abandoned Lemko farm in the village of Zyndranowa. In the beginning, it was called the Hall of Lemko Culture Memorabilia but the name was later changed to the Museum of Lemko Culture. Their activity encountered difficulties from the communist authorities, particularly the local ones, who aimed to liquidate the museum. Among the main obstacles to achieving their goal were that the museum belonged to Teodor Gocz and the Lemko activists were determined to save the material traces of Lemko culture. The transformation of the Polish political system into a democratic one meant better times for the Lemko museum though it still faced problems to obtain money for its ongoing activity and overcome the reluctance of the local authorities and other museums. Nevertheless, the Museum of Lemko Culture has developed into an open-air museum and constitutes a connecting link between the deported Lemkos and their descendants with their old homeland.

GT-DTW: Bridging Graph Theory and Dynamic Time Warping for Complex Time Series Analysis
Authors: Mahajan Sachit
Published: September 2023

Classification of time series data plays a critical role across various domains, enabling pattern recognition and trend prediction. Traditional methods like Dynamic Time Warping (DTW) have been widely used to measure similarity between time series, but there are challenges related to computational complexity and sensitivity to noise. The conventional DTW approach, with its quadratic time complexity, can be inefficient for large datasets, and some implementations may struggle with noise and local variations. To overcome these limitations, a novel method called Graph-Theoretic Dynamic Time Warping (GT-DTW) is proposed. GT-DTW represents each time series as a graph, applies DTW on the graph representations and calculates the distances between different time series based on these graph representations. This approach provides a robust and computationally efficient method for time series classification, and experimental results show that GT-DTW provides better results when compared with conventional methods on the benchmark datasets from the UCR time series database. GT-DTW also demonstrates enhanced effectiveness in situations where time series share fundamental similarities, yet are affected by intricate transformations, noise, inconsistencies in length, and localized distortions.
Machine Learning based Nanowire Classification method based on Nanowire Array Scanning Electron Microscope Images
Authors: Brugnolotto Enrico , Aleksandrov Preslav , Sousa Marilyne , Georgiev Vihar P.
Published: September 2023

This article introduces an innovative classification methodology for identifying nanowires within scanning electron microscope images. Our approach employs advanced image manipulation techniques in conjunction with machine learning-based recognition algorithms. The effectiveness of our proposed method is demonstrated through its application to the categorization of scanning electron microscopy images depicting nanowires arrays. The method’s capability to isolate and distinguish individual nanowires within an array is the primary factor in the observed accuracy. The foundational data set for model training comprises scanning electron microscopy images featuring 240 III-V nanowire arrays grown with metal organic chemical vapor deposition on silicon substrates. Each of these arrays consists of 66 nanowires. The results underscore the model’s proficiency in discerning distinct wire configurations and detecting parasitic crystals. Our approach yields an average F1 score of 0.91, indicating high precision and recall. Such a high level of performance and accuracy of the ML methods demonstrate the viability of our technique for not only academic but also practical commercial implementation and usage.
Robust Constant Curvature Curve Communications with Complex and Quaternion Neural Networks
Authors: Buvarp Anders , Mili Lamine
Published: September 2023

The concept of Digital Twin has recently emerged, which requires the transmission of a massive amount of sensor data with low latency and high reliability. Analog error correction is an attractive method for low-latency communications; hence, in this paper, we propose the use of complex-valued neural networks and Quaternionic Neural Networks (QNNs) to decode analog codes. Furthermore, we propose mapping our codes to the baseband of the frequency domain to enable easy time and frequency synchronization as well as to mitigate frequency-selective fading using robust estimation theory. This is accomplished by applying inverse Discrete Fourier Transform (DFT) modulation, which achieves a significant reduction in hardware complexity, power, and cost as compared to our previously proposed analog coding scheme. Additionally, we introduce a scaled version of our previous analog codes that enables statistical signal processing, something we have not been able to achieve until now. This achieves significant noise immunity with drastic performance improvements at low Signal-to-Noise Ratios (SNR) and a small loss at high SNR.
Threads and Spirals in a Noninteger Dimensional Universe
Authors: Kak Subhash
Published: September 2023

 The paper presents analysis showing that the earliest structures in the evolution of noninteger dimensionality in a system will be threads and spirals. Before the dimensionality has reached 1, the structures are linear, and thereafter these threads or strings begin to bend and fold to be in accord with fundamental scale-invariance requirements. As the evolution proceeds, threads turn into spirals in a manner that parallels phase changes in a liquid crystal. Evidence is presented that the emergence of threads and spirals is consistent with the findings in bioscience, liquid crystals, galactic center filaments, and early spiral galaxies. 
Robust Feature Selection for Continuous BP Estimation in Multiple Populations: Towards Cuffless Ambulatory BP Monitoring
Authors: Cisnal Ana , Li Yanke , Fuchs Bertram , Ejtehadi Mehdi , Riener Robert , Paez Granados Diego
Published: September 2023

Current blood pressure (BP) estimation methods have not achieved an accurate and adaptable approach for application in populations at risk of cardiovascular disease, with generally limited sample sizes. Here, we introduce an algorithm for BP estimation solely reliant on photoplethysmography (PPG) signals and demographic features. Our approach automatically obtains signal features and employs the Markov Blanket (MB) feature selection to discern informative and transmissible features, achieving a robust space adaptable to the population shift.

We validated our approach with the Aurora-BP database, compromising ambulatory wearable cuffless BP measurements for over 500 individuals. By evaluating several machine-learning regression methods, Gradient Boosting emerged as the most effective. The comparative assessment encompassed both a generic model (trained on unclassified BP data) and specialized models (tailored to each distinct BP population), with the former demonstrating consistent superiority with MAE  of 10.2 mmHg (0.28) for systolic BP and 6.7 mmHg (0.18) for diastolic BP on the whole dataset.

Moreover, a comparison of in-clinic and ambulatory model performance showed a significant decrease in accuracy for the latter of 2.85 mmHg in systolic (p < 0.0001, F-value = 32764.76) and 2.82 mmHg for diastolic (p < 0.0001, F-value = 65675.36) estimation errors.

Our work contributes to a resilient BP estimation algorithm from PPG signals, underscoring the advantages of causal feature selection and quantifying the disparities between ambulatory and in-clinic measurements.
Comparing Aerial-RIS- and Aerial-Base-Station-Aided Post-Disaster Cellular Networks
Authors: Matracia Maurilio , kishk mustafa , Alouini Mohamed-Slim
Published: September 2023

 Reconfigurable intelligent surface (RIS) technology and its integration into existing wireless networks have recently attracted much interest. While an important use case of said technology consists in mounting RISs onto unmanned aerial vehicles (UAVs) to support the terrestrial infrastructure in post-disaster scenarios, the current literature lacks an analytical framework that captures the networks’ topological aspects. Therefore, our study borrows stochastic geometry tools to estimate both the average and local coverage probability of a wireless network aided by an aerial RIS (ARIS); in particular, the surviving terrestrial base stations (TBSs) are modeled by means of an inhomogeneous Poisson point process, while the UAV is assumed to hover above the disaster epicenter. Our framework captures important aspects such as the TBSs’ altitude, the fact that they may be in either line-of-sight or non-line-of-sight condition with a given node, and the Nakagami-m fading conditions of wireless links. By leveraging said aspects we accurately evaluate three possible scenarios, where TBSs are either: (i) not aided, (ii) aided by an ARIS, or (iii) aided by an aerial base station (ABS). Our selected numerical results reflect various situations, depending on parameters such as the environment’s urbanization level, disaster radius, and the UAV’s altitude. 
Multi-band Adaptive Impedance Compensation Methods for Spatially Robust Capacitive Power Transfer Systems
Authors: Ahmadi Masoud , Dadashzadeh Hoda , Markley Loïc , Johnson Thomas
Published: September 2023

Our paper compares the merits of using both adaptive load resistance and adaptive frequency for impedance compensation of large spatial variations in capacitive power transfer (CPT) systems. We show through an equivalent circuit model how changes to load impedance or changes to frequency can be used to maintain a constant input impedance to the CPT link as the separation distance between the transmit and receive electrodes is varied. In previous works, frequency compensation required continuous adjustment to track spatial changes, thereby requiring broad operating bands for broad spatial ranges. Here, we combine discrete frequency compensation with continuous impedance compensation to keep transmission frequencies within specific narrowband ISM channels. 

This work presents a practical implementation of spatially robust CPT systems. We consider the limitations of band-limited wireless power channels and apply frequency compensation as discrete frequency changes that are switched between different bands. In this way, frequency compensation offers coarse impedance control for large spatial changes. We then combine the band switching with load impedance compensation methods that offer fine impedance control. Experimental results verify the design concepts using an electrode configuration that is compatible with a differential six-plate CPT system. The results include measurements of the compensated CPT link in isolation as well as an evaluation of compensation applied to an end-to-end system with a class-E amplifier and class-E rectifier.

The results show that multi-band operation significantly extends the spatial robustness of the system. Compared to single-band operation, there is a 50\% increase in the compensation gap range in the dual-band system. The choice between multi-band and single-band systems depends on application requirements: multi-band adaptive load compensation works well in systems with large spatial variations, while single-band suffices for applications with modest spatial variation and defined range constraints.

Integrated Gradients (IG) is the prevalent path attribution method for deep neural networks, involving the integration of gradients along a path from the explained input (explicand) to a counterfactual instance (baseline). Nonetheless, current IG variants exclusively consider the gradient of explicand's output, but we have discovered that the gradient of the counterfactual output also exerts a substantial influence on feature attribution. To achieve this, we propose Iterative Gradient path Integrated Gradients (IG2), considering both two gradients. IG2 incorporates the counterfactual gradient iteratively into the integration path, consequently obtaining a novel path (GradPath) and a novel baseline (GradCF). These two novel IG components effectively address the issues of attribution noise and arbitrary baseline choice in earlier IG methods. IG2, as a path method, stratifies many desirable axioms, which are theoretically justified in the paper. Experimental results on XAI benchmark, ImageNet, MNIST, TREC questions answering, wafer-map failure patterns, and CelebA face attributes validate that IG2 delivers superior feature attributions compared to the state-of-the-art techniques.

Given the rising prevalence of disinformation and fake news online, the detection of fake news in social media posts has become an essential task in the field of natural language processing (NLP). In this paper, we propose a fake detection model named, FakEDAMR that encodes textual content using the Abstract Meaning Representation (AMR) graph, a semantic representation of natural language that captures the underlying meaning of a sentence. The graphical representation of textual content holds longer relation dependency in very few distances. A new fake news dataset, FauxNSA, has been created using tweets from the Twitter platform related to ‘Nupur Sharma’ and ‘Agniveer’ political controversy. We represent each sentence of the tweet using AMR graph and then use this in combination with textual features to classify fake news. Experimental results on two different sets of features show that adding AMR graph features improves F1-score and accuracy. In the experiments, Random Forest with AMR-encoded features outperforms other models in Feature-set 1, achieving 88.90%, 89.48%, 87.09% accuracy and 85.92%, 88.69%, 86.70% F1-score on the FauxNSA, Covid19-FND, and KFN datasets, respectively. However, when Feature-set 2 is used, BiLSTM with AMR-encoded features emerges as the top-performing model. It achieves highest accuracy and F1-score of 93.96% and 91.96% on the dataset. It also maintains high performance on Covid19-FND and KFN datasets, with accuracy and F1-scores of 93.26% and 93.20% on Covid19-FND, and 93.52% and 93.52% on KFN, respectively.

This paper’s purpose is to determine whether certain groups of people are more susceptible to Coronary Heart Disease (CHD) based on their age group and gender. The author attempts to determine whether there is an association between age group and increased susceptibility to CHD in both the male and female population using data on maximum heart rate, total cholesterol, and blood pressure. The author built a device that could measure heart rate using a sensor and a microcontroller. This device was used to collect data on 10 male and 10 female subjects. The data was added to another dataset containing 1025 subjects and statistical analysis was conducted to determine whether there is association between age group and CHD susceptibility in both the male and female populations.

High-accuracy radio positioning and sensing technologies are crucial for many applications, including tracking hospital patients and identifying victims during emergency calls. However, these techniques present serious privacy concerns since malicious actors might use them to track users' activities and habits without their consent. This paper provides a systematic overview of the privacy risks posed by high-accuracy radio positioning and sensing, particularly from physical layer perspectives. To demonstrate a typical risk, we develop an intelligent tracking-without-consent model that can follow a target user in a restricted-access building with 94% accuracy reliability for less than 1m. Our research reveals that none of the privacy-enhancing methods, such as channel state information (CSI) obfuscation and beamforming steering, can totally eliminate tracking, especially in coordinated attempts that use radio location and sensing simultaneously. Furthermore, there is currently no commercial implementation of these techniques integrated into civilian wireless chips that would enable users to be informed about ongoing radio-based surveillance, let alone grant them control over terminating the illegal tracking activity or secluding themselves. In addition, accurately detecting tracking activities by malicious actors in shared wireless networks with a high density of sensors or in advanced communication technologies like 6G mmWave/Terahertz beamforming, which utilizes rich CSI data, continues to pose a challenge. Given the difficulties of totally avoiding signal-based tracking threats, efficient signal encryption and access control mechanisms at the physical layer will be critical research topics for the coming years.
