¿Las comunas de Santiago y Providencia concentran la “cultura” de la provincia de Santiago? / Do the communes of Santiago and Providencia concentrate the “culture” of the province of Santiago?
Authors: Altamirano Arancibia Patricio
Published: October 2021

Se examinan la cantidad de espacios culturales de la provincia de Santiago, constatando la existencia de una concentración de la infraestructura cultural en relación al capital económico de la comuna, destacándose en este sentido las comunas de Santiago y Providencia. Esto sirve para contrastar las categorías de “cultura ilustrada” versus cultura comunitaria (entre otras), estableciendo la existencia de comunas que tendrían un 0% de cultura ilustrada y otras con un 100%, aunque todas tendrían culturas profundas y comunitarias. Este permite cuestionar los instrumentos estadísticos que miden cultura, basados en las categorías de la Unesco, proponiendo el uso de conceptos e instrumentos menos ilustrados que permitan visibilizar la cultura artística comunitaria, sobre todo en las comunas de menores ingresos de la provincia de Santiago.

The amount of cultural spaces in the province of Santiago are examined, finding that a concentration of cultural infrastructure in relation to the economic capital of the commune, standing out in this sense the communes of Santiago and Providencia is presented. This serves to contrast the categories of “ Enlightenment culture “ versus community culture (among others), establishing the existence of communities that have 0% of enlightened culture and others with 100%, although all have deep and community cultures, allowing question the statistical tools that measure culture, based on the categories of Unesco, proposing the use of less enlightened concepts and instruments that allow community visualize artistic culture , especially in lower-income communes of the province of Santiago.
Violencias. Sexos, géneros, sexualidades. / Violence. Sexes, genders, sexualities.
Authors: Di Segni Silvia
Published: October 2021

En este texto se intenta desplegar lo que subyace a un concepto de Preciado que invierte la cuestión de violencia de género sosteniendo que el género mismo es la violencia. Se analizan también otras derivaciones de ese modo de pensar la realidad: que la definición de sólo dos sexos, es violencia; que la heteronormatividad procreativa es violenta. Todo esto en el marco de una psiquiatría que ha patologizado a las víctimas (mujeres y población LGBTIQ) ocultando lo discriminatorio de esa práctica “normalizadora”. Se consideran también los necesario cambios legales y educativos que apunten a igualar derechos y eliminar diferencias desigualadas que sostienen la violencia.

This text aims to unfold the underlying implications of Preciado´s concept that inverts the question of gender violence by holding that gender itself is violence. Other derivations of this way of conceiving reality are also analyzed as follows: that defining only two sexes is violence and that procreating heteronormativity is violent. These notions are framed within a psychiatric conception that has patologized its victims (women and the LGBTIQ population) by hiding how discriminatory this “normalizing” practice can be. The text also considers the necessary legal and educational changes that will lead to equal rights and to suppression of unequal differences that are the basis of violence itself.
Violencia de (L) género: “Hacia una sofística de la materialidad de los cuerpos” / Violent gender: “To a sophistry of the materiality of bodies”
Authors: Reyes Lozano Claudio
Published: October 2021

Los estudios críticos de género sustancialistas desconocen su posición teórico-política en el momento de explayar algunas de sus hipótesis fundamentales. El presente estudio intenta dar cuenta de las consecuencias éticas que asume llevar hasta el final algunas de estas posiciones teóricas. Advertimos así que obras fundamentales de estos estudios se apropian con claridad, y sin saberlo, de una lógica aristotélica para tratar la asunción material del cuerpo, el sujeto y el género ¿Qué encontramos específicamente en esta lógica? Esta última se caracteriza por tener su raíz en una ontología inamovible, en donde cualquier intento de desbaratar el “ser” tiene como respuesta inmediata la exclusión violenta de la diferencia: concretamente observamos esto, dialogando tanto con colegas como legos, en la “violencia académica” pero también en la “violencia cotidiana” ¿Cómo salir del cierre metafísico que ha mantenido durante décadas la violencia y exclusión de aquello que se generó en primera instancia, paradójicamente, como argumentación de tolerancia y emancipación? Pensamos que deconstruyendo el discurso de género aristotélico podremos vislumbrar nuevas hipótesis y posiciones ético-políticas que no recurran, para validarse, a la exclusión violenta de nuevos cuerpos-sujetos-géneros.

Some critical gender studies do not know their theoretical and political position at the time to developing some of their basic assumptions. This study attempts to explain the ethical consequences that lead to the end some of these theoretical positions. We realize that fundamental works of these studies clearly appropriating, and without knowing it, an aristotelian logic to justify the assumption of material body, the subject and gender. What specifically found in this logic? It is characterized to found on an immovable ontology, where any attempt to disrupt the “being” has as an immediate violent response to exclude the difference: specifically we observe this, dialoguing with colleagues and laymen, in the “academic violence” but also “everyday violence”. How to get out of the metaphysical closure that maintained for decades the violence and exclusion of what is generated in the first place, paradoxically, as argument of tolerance and emancipation? We think deconstructing the aristotelian discourse of gender can warn new hypotheses and ethical positions that not based, to validate, on a violent exclusion of new bodies-subject-genres positions.

En el contexto de los debates feministas en torno a la feminización del trabajo productivo contemporáneo, este artículo presenta los resultados de una investigación empírica con cajeras de grandes cadenas de supermercado en Santiago de Chile, que buscaba relevar los referentes identificatorios de género que estas trabajadoras utilizan para dotar de sentido a su oficio, junto con las formas en que estos referentes se movilizan para ejercer diversas demandas de reconocimiento. Los resultados muestran el despliegue de tres referentes identificatorios construidos desde el género que conforman demandas de reconocimiento: referentes identificatorios como agentes creadoras en el trabajo, como mujeres sacrificadas o como cuerpo femenino sujeto a necesidades.

In the context of the feminist debates about the feminization of contemporary productive work, this article presents the results of empirical research with cashiers of hypermarket chains in Santiago of Chile, which sought to identify the gender identification references that these workers use to give meaning to their labor, along with the ways in which these referents are mobilized to exercise various demands for recognition. The results show the deployment of three identification referents constructed from the gender that make up demands for visibility of some dimension of their woman, whether as a worker, as a sacrificed woman or as a body subject to needs.

Czyn niepodległościowy Józefa Piłsudskiego a zjawiska zdrady i szpiegostwa. Wybrane aspekty
Authors: Paduszek Konrad
Published: October 2021

W latach czynu niepodległościowego Józefa Piłsudskiego (od czasów jego działalności konspiracyjnej po odrodzenie Rzeczypospolitej) intensywnie rozwijały się instytucje wywiadu, kontrwywiadu i policji politycznych w państwach zaborców, a po odzyskaniu niepodległości – we wrogich Polsce państwach sąsiednich. Następstwem podejmowanych przez te instytucje działań – infiltracji, inwigilacji i prowokacji, były zjawiska zdrady i szpiegostwa. Taki stan rzeczy wpłynął na formy, metody i możliwości walki Józefa Piłsudskiego o niepodległość, zarówno wtedy, gdy działał w konspiracji, jak i później, gdy pełnił funkcje naczelnego wodza oraz naczelnika państwa.
W artykule opisano wybrane przypadki zdrady i szpiegostwa oraz środki przeciwdziałania im w warunkach działalności konspiracyjnej i odrodzonego państwa polskiego. Omówiono formy, metody i możliwości działań niepodległościowych podejmowanych przez Józefa Piłsudskiego w obliczu zdrady i szpiegostwa oraz jego stosunek do tych zjawisk.
Reef-Fish Abundance, Biomass, and Biodiversity Inside and Outside No-Take Marine Zones in the Florida Keys National Marine Sanctuary: 1999–2018

Published: October 2021

Observations from the Reef Visual Census program in the Florida Keys National Marine Sanctuary (FKNMS) between 1999 and 2018 were used as a US Marine Biodiversity Observation Network case study to assess whether differences in biodiversity metrics (abundance, biomass, richness, Simpson diversity, and functional diversity) occurred across regions with different habitat types (high-relief, linear, and patch reefs), protection levels (no-take and unprotected zones), and types of protected zones. Protected areas had higher reef-fish biomass compared to unprotected areas at the beginning of the observation period, but these metrics decreased over time. We did not detect an effect of size of no-take marine zones, but rather found that large (18.7 km2) and small (average of 0.85 km2) areas had similar reef-fish abundance, biomass, and diversity indices. High-relief reef habitats had the greatest reef-fish abundance (20%–30%) and species richness (~20%), and nearly twice the biomass of other habitat strata, but biomass decreased 20%–30% in linear and patch reefs after 2007. Although high-relief reefs are important for biodiversity conservation and restoration, policies should address the decline in fish abundance, biomass, and diversity observed throughout the FKNMS. Monitoring should be sustained to support policies and respond to changing conditions related to climate change and resource use.
Timing Analysis of Algorithm Substitution Attacks in a Post-Quantum TLS Protocol
Authors: Marchiori Dúnia , Giron Alexandre A. , Nascimento João Pedro A. do , Custódio Ricardo
Published: October 2021

Snowden's revelations about mass surveillance brought to public attention devastating attacks on cryptographic algorithm implementations. One of the most prominent subsets of these attacks is called Algorithm Substitution Attacks (ASA), where a subverted implementation leaks sensitive information. Recently, it has been proposed to modify TLS implementations to use Post-Quantum Cryptography (PQC). In this paper, we propose and analyze ASA in two PQC schemes that can be used in TLS. We attacked the Kyber Key Encapsulation Mechanism (KEM) and Falcon Signature and successfully deployed them in a TLS implementation. Results show that timing analysis can distinguish our Falcon subversion, but it is not enough to detect our attacks deployed in TLS.

Com a utilização de sistemas de detecção de intrusão e a necessidade de aprimorar suas classificações e desempenho, o presente trabalho objetiva-se no estudo de classificadores utilizando aprendizado de máquina e, em especial métodos adversariais. A principal contribuição deste estudo é a validação do benefício de Métodos de Aprendizado de Máquina Adversariais na detecção de anomalias em redes de computadores. Para tanto, procede-se a realização de experimentos com diversos classificadores em um conjunto de dados com diferentes ataques através de experimentos com amostras alteradas no intuito de observar o comportamento dos classificadores. Desse modo, observa-se que os resultados foram promissores, condizentes com demais trabalhos semelhantes, indicando o melhor classificador e a melhor métrica para cada tipo de ataque bem como a melhor métrica para avaliação dos resultados e os parâmetros mais relevantes para correção das classificações rotuladas incorretamente. Conclui-se que os métodos adversariais, baseados em amostras alteradas para corrigir classificações equivocadas, podem ser adequados no aprimoramento de métodos de classificação baseados em inteligência artificial. A métrica F1- Score alcançada para cada categoria de ataque foi 0,99 para DoS, 0,99 para Probe, 0,95 para R2L e 0,65 para U2R, considerando o conjunto de dados NSL-KDD.

Authors: Abreu Diego , Carvalho Igor , Abelém Antônio
Published: October 2021

O aprendizado de máquina por stream possibilita a detecção de ataques de rede em tempo real, processando as instâncias e inspecionando-as apenas uma vez. Entretanto, as características de rede utilizadas por esses sistemas são dinâmicas e podem se tornar redundantes ou irrelevantes durante o processo de detecção, o que impacta diretamente no desempenho desses algoritmos, dificultando a implementação dessas propostas em ambientes reais. Neste trabalho propomos a utilização de técnicas de seleção de características em stream para melhorar o desempenho da detecção de ataques de rede. Nossos resultados, utilizando três bases de referência em segurança, mostram que a seleção de característica impacta diretamente na detecção dos ataques, com redução de até 93% no tempo de detecção.

As redes de sobreposição peer-to-peer (P2P) baseadas em Distributed Hash Table (DHT) tem ganhado atenção na literatura devido as suas características como alta disponibilidade, escalabilidade, entre outras. Uma implementação popularmente conhecida é o projeto OpenDHT, contudo, não é abordada a autenticidade dos nós, nem das mensagens. Dessa forma, ela é suscetível a diversos ataques, entre eles, ataque Sybil. O objetivo do trabalho é apresentar uma proposta para preencher essa lacuna através de uma Infraestrutura de Chave Pública (ICP). Os resultados obtidos através da ferramenta Scyther demonstram a segurança do protocolo de autenticação contra ataques bem conhecidos e os testes práticos demonstram êxito da implementação.

An Improved Tool for Detection of XSS Attacks by Combining CNN with LSTM
Authors: Lente Caio , Hirata Jr. Roberto , Batista Daniel Macêdo
Published: October 2021

Cross-Site Scripting (XSS) is still a significant threat to web applications. By combining Convolutional Neural Networks (CNN) with Long ShortTerm Memory (LSTM) techniques, researchers have developed a deep learning system called 3C-LSTM that achieves upwards of 99.4% accuracy when predicting whether a new URL corresponds to a benign locator or an XSS attack. This paper improves on 3C-LSTM by proposing different network architectures and validation strategies and identifying the optimal structure for a more efficient, yet similarly accurate, version of 3C-LSTM. The authors identify larger batch sizes, smaller inputs, and cross-validation removal as modifications to achieve a speedup of around 3.9 times in the training step.

Published: October 2021

O artigo tem como objetivo apresentar e analisar o método de teste de elasticidade de Penélope Watkins, bem como averiguar o método de cálculo de redução dos moldes para o vestuário em malha. Para isto, utilizou-se dois tipos de malhas: uma com 84% de poliamida e 16% de elastano e outra com 92% de poliéster e 8% de elastano. Como resultado, foram confeccionados dois collants que se apresentaram ajustados demasiadamente ao corpo, em vista da largura da amostra do teste de elasticidade ser muito estreita. Sendo assim, os autores deste artigo propuseram uma nova largura de amostra e dois novos collants foram refeitos, seguindo as diretrizes de Watkins. Os resultados mostraram uma distorção mais adequada das malhas nas peças confeccionadas.

Advantages of a combination of PD and PID controller over PID controller in the example of quadcopter control and stabilization
Authors: Božić Milan , Vasiljević-Toskić Marko , Bodić Milan , Rajs Vladimir
Published: October 2021

This paper presents the problem of control and stabilization of a quadcopter in a real environment and one of the solutions to improve the classical PID controller by applying a combination of PID and PD controller. An algorithm for implementing a PID controller in a discrete form is given, with the possibility of switching off the integral effect of the controller during operation, thereby achieving the PID-PD controller. The criterion for switching the I controller on and off depending on the size of the controller input error is shown. Other ways of discriminating against I regulators are also listed and a brief overview is given. The results were obtained in computer simulations using the example of an arbitrary system controlled by a PID controller then the controller was replaced with a new PID-PD controller and the results are shown in graphs. The second test was performed experimentally by testing on the OROZ (quadcopter) development system, which enabled real-time monitoring of the system response, providing data via Bluetooth communication so that data from the real system could also be displayed on the graph. Both management modes (PID and PID-PD) from the development system are shown in graphs. In conclusion, a comparison of the two types of controllers was made, as well as a comparison of simulation results and results from a real environment, and an explanation of the justification for using a new type of controller was given.

The concentration of Fe in aluminum alloy can affect the plasticity, heat resistance, strength and stress corrosion resistance of the alloy. The quantitative analysis of aluminum alloy composition is an important part of the online detection of alloy composition. To improve the quantitative analysis accuracy of Fe in aluminum alloy, the spatial confinement nanosecond laser-induced breakdown spectroscopy is combined with the gradient-descent method. By collecting laser-induced aluminum alloy plasma emission spectra, it is found that the plasma radiation intensity under the confinement of the plate space is significantly enhanced. The enhancement factor of the plasma emission spectrum with a plate spacing of 10 mm is 2.3. The internal standard method and the gradient descent method are used to establish the calibration models respectively, and the values of fitting coefficient (R2), root mean square error (RMSE) and average relative error (ARE) of the two models are compared. Without plate spatial confinement, the R2, RMSEC, RMSEP and ARE of the Fe element calculated by the internal standard method are 90.66%, 0.1903%, 0.1910% and 9.2220%, respectively. The R2, RMSEC, RMSEP and ARE of Fe element obtained by the gradient descent method are 97.12%, 0.1467% (weight concentration), 0.1124% (weight concentration) and 7.1373%, respectively. With the plate spatial confinement, the R2, RMSEC, RMSEP and ARE of Fe element calculated by the internal standard method are 95.22%, 0.1409% (weight concentration), 0.1401% (weight concentration), and 6.8893%, respectively. The R2, RMSEC, RMSEP and ARE of Fe element obtained by the gradient descent method are 99.22%, 0.0731% (weight concentration), 0.0756% (weight concentration) and 3.5521%, respectively. Comparing with the internal calibration model, the accuracy and stability of the gradient descent calibration model are improved. The spatial confinement LIBS combined with the gradient descent method can effectively reduce the influence of the alloy matrix effect and the self-absorption effect on the quantitative analysis.
How Not to Study a Disease
Authors: Herrup Karl
Published: October 2021

An authority on Alzheimer's disease offers a history of past failures and a roadmap that points us in a new direction in our journey to a cure.

For decades, some of our best and brightest medical scientists have dedicated themselves to finding a cure for Alzheimer's disease. What happened? Where is the cure? The biggest breakthroughs occurred twenty-five years ago, with little progress since. In How Not to Study a Disease, neurobiologist Karl Herrup explains why the Alzheimer's discoveries of the 1990s didn't bear fruit and maps a direction for future research. Herrup describes the research, explains what's taking so long, and offers an approach for resetting future research.

Herrup offers a unique insider's perspective, describing the red flags that science ignored in the rush to find a cure. He is unsparing in calling out the stubbornness, greed, and bad advice that has hamstrung the field, but his final message is a largely optimistic one. Herrup presents a new and sweeping vision of the field that includes a redefinition of the disease and a fresh conceptualization of aging and dementia that asks us to imagine the brain as a series of interconnected “neighborhoods.” He calls for changes in virtually every aspect of the Alzheimer's disease research effort, from the drug development process, to the mechanisms of support for basic research, to the often-overlooked role of the scientific media, and more. With How Not to Study a Disease, Herrup provides a roadmap that points us in a new direction in our journey to a cure for Alzheimer's.
Media Disrupted
Authors: Lotz Amanda D.
Published: October 2021

How the internet disrupted the recorded music, newspaper, film, and television industries and what this tells us about surviving technological disruption.

Much of what we think we know about how the internet “disrupted” media industries is wrong. Piracy did not wreck the recording industry, Netflix isn't killing Hollywood movies, and information does not want to be free. In Media Disrupted, Amanda Lotz looks at what really happened when the recorded music, newspaper, film, and television industries were the ground zero of digital disruption. It's not that digital technologies introduced “new media,” Lotz explains; rather, they offered existing media new tools for reaching people.

For example, the MP3 unbundled recorded music; as the internet enabled new ways for people to experience and pay for music, the primary source of revenue for the recorded music industry shifted from selling music to licensing it. Cable television providers, written off as predigital dinosaurs, became the dominant internet service providers. News organizations struggled to remake businesses in the face of steep declines in advertiser spending, while the film industry split its business among movies that compelled people to go to theaters and others that are better suited for streaming. Lotz looks in detail at how and why internet distribution disrupted each industry. The stories of business transformation she tells offer lessons for surviving and even thriving in the face of epoch-making technological change.

With the recent explosion in high-resolution protein structures, one of the next frontiers in biology is elucidating the mechanisms by which conformational rearrangements in proteins are regulated to meet the needs of cells under changing conditions. Rigorously measuring protein energetics and dynamics requires the development of new methods that can resolve structural heterogeneity and conformational distributions. We have previously developed steady-state transition metal ion fluorescence resonance energy transfer (tmFRET) approaches using a fluorescent noncanonical amino acid donor (Anap) and transition metal ion acceptor to probe conformational rearrangements in soluble and membrane proteins. Here, we show that the fluorescent noncanonical amino acid Acd has superior photophysical properties that extend its utility as a donor for tmFRET. Using maltose-binding protein (MBP) expressed in mammalian cells as a model system, we show that Acd is comparable to Anap in steady-state tmFRET experiments and that its long, single-exponential lifetime is better suited for probing conformational distributions using time-resolved FRET. These experiments reveal differences in heterogeneity in the apo and holo conformational states of MBP and produce accurate quantification of the distributions among apo and holo conformational states at subsaturating maltose concentrations. Our new approach using Acd for time-resolved tmFRET sets the stage for measuring the energetics of conformational rearrangements in soluble and membrane proteins in near-native conditions.
Visually induced changes in cytokine production in the chick choroid
Authors: Summers Jody A , Martinez Elizabeth
Published: October 2021

Postnatal ocular growth is regulated by a vision-dependent mechanism that acts to minimize refractive error through coordinated growth of the ocular tissues. Of great interest is the identification of the chemical signals that control visually guided ocular growth. Here, we provide evidence that the pro-inflammatory cytokine, interleukin-6 (IL-6), may play a pivotal role in the control of ocular growth using a chicken model of myopia. Microarray, real-time RT-qPCR, and ELISA analyses identified IL-6 upregulation in the choroids of chick eyes under two visual conditions that introduce myopic defocus and slow the rate of ocular elongation (recovery from induced myopia and compensation for positive lenses). Intraocular administration of atropine, an agent known to slow ocular elongation, also resulted in an increase in choroidal IL-6 gene expression. Nitric oxide appears to directly or indirectly upregulate choroidal IL-6 gene expression, as administration of the non-specific nitric oxide synthase inhibitor, L-NAME, inhibited choroidal IL-6 gene expression, and application of a nitric oxide donor stimulated IL-6 gene and protein expression in isolated chick choroids. Considering the pleiotropic nature of IL-6 and its involvement in many biological processes, these results suggest that IL-6 may mediate many aspects of the choroidal response in the control of ocular growth.
Martín Lutero: Carta sobre el arte de traducir (1530). Sobre la traducción, la hermenéutica bíblica y la opción dogmática de la Reforma
Authors:   Departamento de Humanidades y Filosofía, Universidad Loyola Andalucía, Pena-Búa Pilar
Published: October 2021

La Carta sobre el arte de traducir ha sido considerada generalmente como un clásico de la teoría de la traducción, en la que Lutero habría expuesto, de manera original y novedosa, un método para interpretar los textos bíblicos y analizar el desempeño del traductor. Esta aportación estudia la contribución del reformador a la traductología bíblica y concluye que ésta no sólo no es original, sino una excusa para reafirmar la doctrina de la justificación evangélica en el marco de la Confesión de Augsburgo, leída ante el Emperador en 1530

Esta investigación se aboca a la contribución de los obispos latinoamericanos y caribeños en la confección de Optatam totius, el decreto conciliar dedicado a la formación de los presbíteros. En un primer apartado, el estudio se detiene en el tiempo anterior al Concilio, a saber, las fases antepreparatoria y preparatoria. En esta sección se da cuenta principalmente de las respuestas (vota) que los obispos dieron a las preguntas hechas por Juan XXIII con motivo de la convocación del Concilio, y las discusiones que se dieron a su propósito. En un segundo apartado, este artículo trata del aporte de los latinoamericanos durante el mismo Vaticano II. Por último, se examina el influjo que ha podido tener la contribución latinoamericana en el documento final aprobado por la asamblea conciliar

This study investigated whether men with a history of real‐life aggressive, dominant behavior show increases in testosterone and cortisol levels after brief social contact with women. Furthermore, we tested the prediction that such changes in hormones would be larger than those observed previously in young male students. Sixty‐seven male participants convicted of intimate partner violence (IPV) either had brief social contact with a female confederate (experimental condition) or a male confederate (control condition). We also performed meta‐analyses to investigate whether IPV perpetrators' hormonal responses were larger than the typical responses of young male students in prior studies. All statistical analyses were preregistered. Change in testosterone did not differ across experimental conditions, and testosterone in the IPV perpetrators actually declined from baseline in the female confederate condition. Our meta‐analysis showed that this testosterone decrease was different from the testosterone increase typically observed in young male students. The cortisol levels of IPV perpetrators did not change in response to contact with women. This result was consistent with our meta‐analysis since young male students also did not experience a cortisol change in response to interactions with women. In sum, our findings provide no evidence that male IPV perpetrators exhibit larger hormone increases to brief interactions with women, although it is possible that the men in this sample did not perceive the social contact period as a courtship opportunity. These results suggest that hormone reactivity to social encounters may differ across subject populations and depend on how subjects perceive social situations within laboratory settings.
The effect of evidence order on jurors' verdicts: Primacy and recency effects with strongly and weakly probative evidence
Authors: Schweitzer Kimberly , Nuñez Narina
Published: October 2021

In a series of studies, the effect of evidence order with strongly and weakly probative evidence was examined. In studies 1a, 1b, and 2, participants read a homicide trial containing four pieces of evidence (two strongly probative, two weakly) presented in differing orders and reported their verdicts. In Study 1a and 1b, fingerprint evidence and a video confession were strongly probative, while DNA evidence and eyewitness testimony were not. In Study 2, DNA and video confession evidence were strongly probative, but fingerprint evidence and eyewitness testimony were not. Across studies, results indicated recency effects when the last piece of evidence was strongly probative, with more guilty verdicts compared to when the last piece of evidence was weakly probative. Study 3 utilized a different trial scenario and six pieces of evidence to further test for a primacy effect. Results again indicated support for a recency effect, with no primacy effects found.
Finite‐time and fixed‐time synchronization of fuzzy Clifford‐valued Cohen‐Grossberg neural networks with discontinuous activations and time‐varying delays

Published: October 2021

In this article, we are concerned with fuzzy Clifford‐valued Cohen‐Grossberg neural networks (FCVCGNNs) via discontinuous activations and time‐varying delays. First, the time‐delayed feedback strategy is used to investigate the synchronization in finite‐time and fixed‐time of FCVCGNNs with discontinuous activations and time‐varying delays. By designing Lyapunov functions and utilizing differential inequalities, several effective conditions are derived to ensure synchronization in finite‐time and fixed‐time of the addressed neural networks. A novel fixed‐time convergence method is proposed to study synchronization in fixed‐time of discontinuous delayed FCVCGNNs. Furthermore, the settling time of synchronization are estimated. In the end, two numerical examples with simulations are given to confirm the effectiveness of the synchronization criteria.

Geometrical structuring of monolithic metal‐organic frameworks (MOFs) components is required for their practical implementation in many areas, including electronic devices, gas storage/separation, catalysis, energy storage as well as bio‐medical applications. Despite progress in structuring MOFs, an approach for the precise patterning of MOF functional geometries in the millimeter‐ to micro‐meter depth is lacking. Here, a facile and flexible concept for the microfabrication of complex MOF patterns on large surfaces is reported. The method relies on the engineering of easily‐writable sheets of precursor metal oxide nanoparticles. The gas‐phase conversion of these patterned ceramic nanoparticle sheets results in monolithic MOF objects with arbitrarily shaped geometries and thicknesses of up to hundreds of micrometers. The writing of complex patterns of zeolitic imidazolate framework‐8 (ZIF‐8) is demonstrated by a variety of approaches including ion beam, laser, and hand writing. Nanometer‐scale patterns are achieved by focused ion beam (FIB). Artless handwritings are obtained by using a pen in a similar fashion to writing on a paper. The pure ZIF‐8 composition of the resulting patterns is confirmed by a series of physical and chemical characterization. This facile MOF precursor‐writing approach provides novel opportunities for the design of MOF‐based devices with applications ranging from micro‐fluidics to renewable energy systems.
