Abstract. This comprehensive study analyzed aerosol products from six low-Earth orbit (LEO) and geostationary Earth orbit (GEO) sensors. LEO sensors like the MODerate resolution Imaging Spectroradiometer (MODIS) and VIsible InfraRed Suite (VIIRS) provide one to two daily global measurements, while GEO sensors (Advanced Himawari Imager: AHI, Advanced Baseline Imager: ABI) offer high-frequency data (∼ 10 min) over specific regions. The combination of LEO and GEO capabilities offers expanded coverage of the global aerosol system if aerosol retrievals are applied consistently across all sensors and packaged in an easy-to-use product. The Dark Target aerosol retrieval algorithm was applied to the six sensors, and the resulting Level 2 aerosol optical depth (AOD) products were gridded and merged into a Level 3 quarter-degree latitude–longitude grid with a 30 min temporal resolution, providing the necessary consistency and packaging. Validation of this packaged Level 3 AOD product against Aerosol Robotics NETwork (AERONET) measurements across global locations showcased the merged product's robustness with a correlation coefficient of 0.83, revealing a global mean bias of approximately ±0.05, with 65.5 % of retrievals falling within an expected uncertainty range, underlining the reliability of the dataset. The new gridded Level 3 dataset significantly improved daily global coverage to nearly 45 %, overcoming the limitations of individual sensors, which typically range from 12 % to 25 %. Furthermore, this merged dataset approximates the diurnal cycle of AOD observed by AERONET, thus offering insights into diurnal signatures retrieved elsewhere. The resulting dataset's high spatiotemporal resolution and improved global coverage, especially in regions covered by GEO sensors (Americas and Asia), make it a valuable tool for diverse applications. Tracking aerosol transport from phenomena like wildfires and dust storms is gaining precision, enabling enhanced air quality forecasting and hindcasting. Additionally, the study positions the merged dataset as a significant asset for evaluating and intercomparing regional or global model simulations, which was previously unattainable in such a gridded format. The dataset and fusion framework layout in this study have the potential to include data from recently (future) launched other GEO (FCI, AMI) and LEO (PACE, VIIRS-JPSS) sensors.
Cutting-Edge Approach to Targeted Therapy: Repositioning of Old Drugs in Combination with Standard Clinical Chemotherapeutics Potentiates a Propitious Novel Targeted Therapy for Human Pancreatic Cancer

Metastatic pancreatic cancer leads to a fatal outcome, with a median progression-free survival of approximately six months when utilizing the most successful combination of chemotherapeutic regimens. When drug resistance develops, it facilitates an increase in primary tumor growth and new and growing metastases. Patients inevitably and quickly succumb to their disease and die. Notably, chemotherapy has an unintended impact on the development of drug resistance through the enhancement of EMT development and the enrichment of cancer stem cells (CSC). Recent report discovered that neuraminidase-1 (Neu-1) regulates EMT induction, angiogenesis, and cellular proliferation by the activation of several receptor tyrosine kinases. Here, the continual therapeutic inhibition of Neu-1 through intravenous administration of oseltamivir phosphate (OP) and aspirin (ASA) alongside GEM treatment significantly inhibits tumor progression, crucial compensatory signaling pathways, EMT program, CSC, and metastasis progression in a preclinical RAG2xCy double mutant BALB/c mouse model of human PANC-1 pancreatic cancer. The tumorigenic and metastatic potential of the xenotumors from the animals treated with the experimental protocols were significantly ablated when transferred into the mammary fat pads of NSG (NOD SCID gamma) branded mice.

Critique de la raison et écriture de la « réson »
Authors: Perreault Isabelle 
Published: September 2024

Cet article articule la mise en échec du rationalisme et la valorisation du sensible et de la porosité du sujet avec le monde comme marques d’affirmation d’une écriture-femme dans l’œuvre de Duras. Comme absent à lui-même, le sujet durassien aurait pour condition existentielle l’ouverture au tout-venant du sensible, dans un renversement de l’axiome cartésien – « Je pense donc je suis ». Les héroïnes féminines, les enfants, les aliénés incarneraient au mieux cet en-allé constitutif de l’être-au-monde durassien. Il n’est pas étonnant que ces figures soient celles qui entretiennent un lien privilégié avec la musique, de tout temps accusée d’irrationnalité et de tromperie par les philosophes. En suivant le fil qui conduit d’une condamnation du discours théorique à une éthique du non-savoir et au rapt du sujet, l’article réévalue le féminisme ambivalent de l’auteure au prisme d’une « attentionnalité », qui substituerait l’intentionnalité du sujet masculin par des formes d’écoute et d’ouverture par lesquelles le soi et le monde perdent leur étanchéité pour devenir des lieux de résonance, de fluidité, de communauté.
Histoire de petits pieds ou de poussins
Authors: Ueda Akiko 
Published: September 2024

« Les petits pieds de la Chine », texte inédit de Marguerite Duras, déconstruit les frontières artificielles et contrecarre les prétentions de la raison. Le récit, qui avance par le biais d’une réitération de la négation et de la contradiction, révèle cette vérité selon laquelle nous ne sommes pas indépendants et que nous ne nous contrôlons pas nous-mêmes. Revenir à l’enfance, au temps des petits pieds et des poussins enfermés et aveugles, revient en définitive à être seul, sans recours, sans issue, sans maîtrise, en proie à ce qui dépasse infiniment, à s’installer dans ce lieu invivable de la perte et du désir dans lequel on n’était pas encore séparé « des autres ». Penser cette première négation, c’est faire valoir le relationnel, une vision plus existentielle que spéculative. À travers les théories d’Eva Feder Kittay, de Søren Kierkegaard ou de Slavoj Žižek, cet article met en relief l’importance de la négativité dans l’œuvre durassienne.
Entre positions politiques et oppositions à la politique
Authors: Chen Xiaolin 
Published: September 2024

Il semble que Marguerite Duras, qui accorde une suprématie totale à l’écriture, cherche à éviter à tout prix qu’elle soit interprétée sous l’angle politique, tant elle a été chagrinée par les lectures de droite qui ont sévi après la sortie du Barrage contre le Pacifique. Cependant, loin de chasser la politique de son univers artistique, l’auteure écrit un grand nombre de livres « dits politiques », dans lesquels la politique s’apparente moins à une revendication réactionnaire qu’à un abandon de toute idéologie et de toute morale – une vision politique nihiliste représentée autant par la perdition réclamée par ses personnages que par un style qui se disloque et se libère des carcans jusqu’à devenir « écriture courante ».
La guerra de Troya en la biblioteca del Marqués de Santillana: manuscritos y lecturas
Authors: Rodríguez Porto Rosa 
Published: September 2024

Aunque la presencia de la materia troyana en la obra del Marqués de Santillana ha sido glosada por otros autores, este trabajo trata de completar y matizar aportaciones previas, partiendo del examen de los manuscritos preservados en su biblioteca. Estos habrían incluido la Crónica Troyana de Juan Fernández de Heredia (Madrid, BNE, MSS/10801), la traducción castellana de la versión latina de la Ilíada debida a Pier Candido Decembrio y Leonardo Bruni (Londres, BL, Add. 21245), así como los romanceamientos de la Genealogia deorum de Boccaccio (Madrid, BNE, MSS/10221) y del Ovidius Moralizatus de Bersuire (Madrid, BNE, MSS/10196), además de otras obras –clásicas y modernas– que llegó a reunir. El análisis de las ilustraciones, manecillas, anotaciones y demás signos de lectura en sus páginas permite seguir el proceso creativo del poeta, reconstruyendo una constelación textual y delineando los contornos de un imaginario que, si bien deudor de la tradición medieval –y muy especialmente de lo alfonsí–, ya participa de una nueva estética.

Published: September 2024

Dentro da temática “O Desafio das Cidades pelo Planeta”, cujo acrônimo em inglês é One Planet City Challenge (OPCC), o grande desafio é lidar especificamente com as questões intrinsecas relacionadas com o crescimento populacional, degradação ambiental e mudanças climáticas, destacando a necessidade da utilização de infraestruturas verdes urbanas como uma das alternativas bastantes viáveis na constante busca de soluções para tais desafios. A ausência das infraestruturas verdes nos grandes centros urbanos pode resultar em uma série de consequências, incluindo o crescimento populacional desordenado, perda de biodiversidade e degradação da qualidade de vida urbana. Sendo assim, e dentro desse contexto, o presente trabalho teve como objetivo realizar um estudo de revisão bibliográfica sobre a importância das estruturas verdes urbanas para as grandes cidades. Para tanto, utilizou-se a Metodologia Prisma cuja pesquisa concentrou-se em artigos científicos publicados entre os anos de 2019 a 2024. Foram utilizados mais de 5.000 bases de dados para identificar estudos relevantes. Na seleção dos artigos, foram incluídos rigorosamente 30 estudos na revisão que foram relevantes para a pesquisa propriamente dita. Os resultados obtidos mostraram que as infraestruturas verdes são fundamentais para promover a sustentabilidade urbana, proporcionando uma série de benefícios sociais, ambientais e econômicos. Foram destacados também, os aspectos negativos, tais como: a falta de incentivos econômicos e políticos. Assim, as infraestruturas verdes são de fundamental importância para melhoria da qualidade de vida urbana e na mitigação dos impactos das mudanças climáticas. Entretanto são necessárias políticas públicas adequadas para que as estruturas verdes sejam implementadas eficazmente nos grandes centros urbanos.
Educação profissional e tecnológica e relações de gênero: uma pesquisa do tipo estado do conhecimento

Published: September 2024

Este artigo investiga como são percebidas as questões de gênero na educação profissional tendo em vista a realidade educacional dos Institutos Federais de Educação. Apresenta os conceitos de acepção de gênero incluindo o contexto histórico em que surgiram. Fundamentou-se em estudos teóricos que abordam o tema, com o suporte do Estado do Conhecimento, apresentando e discutindo conceitos e conexões. Realizou-se uma breve retrospectiva histórica do Ensino Técnico no Brasil, centrada na formação profissional, observando algumas transformações ocorridas até a atual configuração Rede Federal de Educação Profissional, Científica e Tecnológica (RFEPCT). Ante às abordagens da temática de gênero, destacou-se a importância de se trabalhar esse tema no sentido de construir uma trajetória de combate às hierarquias dessa natureza, dentro da EPT, um espaço de formação para o trabalho e a vida. Concluiu-se que discorrer sobre essas questões é, ainda, um assunto carregado de tabus e estigmas. Também se verificou que a busca da educação se reflete não só nas relações dos espaços escolares, mas também em uma futura transformação no mundo do trabalho, pois ambos estão atravessados por disputas, conflitos e contradições nas relações de poder e gênero.
La constitution d’un réseau antimesures sanitaires québécois sur Twitter et la mise en scène d’un populisme par le bas
Authors: Campana Aurélie , Tanner Samuel 
Published: September 2024

Cet article interroge les premières étapes de la constitution d’un réseau antimesures sanitaires québécois sur Twitter entre le 12 mars, date de l’annonce par le premier ministre du Québec des premières restrictions sanitaires, et le 31 mars 2020. Basé sur une approche sociotechnique, il se penche sur l’assemblage des discours antisanitaires et le rôle des différents acteurs, humains et technologiques, qui contribuent à en dessiner les contours et en fabriquer le contenu. Par l’analyse des quatre étapes qui ponctuent l’élaboration d’un réseau – la problématisation, l’intéressement, l’enrôlement et la mobilisation des alliés –, il montre comment se dessine au fil des échanges un populisme par le bas, alimenté par des théories du complot, qui contribuent à cristalliser une opposition entre les élites et le peuple. La stabilisation de l’identité de ce réseau ne se fonde ainsi par sur un substrat de faits partagés ou sur une grille de lecture commune de la crise sanitaire, mais sur une posture de dénonciation des élites politiques, économiques et scientifiques. Elle permet ainsi la convergence des « anti- », y compris les antivaccins, les antienvironnementalistes et les antipluralistes, mais surtout les antiélites et les antisystèmes, et participe très tôt dans la crise provoquée par la COVID‑19 à l’élargissement du réseau.
Complotisme et extrémismes. Le cas de l’extrême droite
Authors: Lefebvre Solange , Colin Mathieu 
Published: September 2024

Cet article explore l’impact des médias sociaux au regard de l’extrémisme et du conspirationnisme. La période récente a notamment montré que l’extrême droite représentait une menace de plus en plus concrète dans la sphère publique, en témoigne l’influence de mouvements comme QAnon ou l’assaut du Capitole du 6 janvier 2021. En utilisant les résultats d’un projet de recherche sur les médias et l’extrémisme réalisé au Québec entre 2017 et 2021, cet article montre que l’extrême droite fait une utilisation particulière des médias sociaux, et que ceux-ci agissent certes comme des chambres d’écho, mais également comme des vecteurs d’une idéologie conspirationniste complexe et protéiforme. Des entretiens qualitatifs avec des individus radicalisés permettent notamment d’illustrer l’intégration idéologique des médiaux sociaux dans la stratégie culturelle et politique de l’extrême droite actuelle.
Can an electron gun solve the outstanding problem of magnetosphere‐ionosphere connectivity?
Authors: Delzanno Gian Luca , Borovsky Joseph E. , Thomsen Michelle F. , Gilchrist Brian E. , Sanchez Ennio 
Published: June 2016

AbstractDetermining the magnetic connectivity between magnetospheric phenomena and ionospheric phenomena is an outstanding problem of magnetospheric and ionospheric physics. Accurately establishing this connectivity could answer a variety of long‐standing questions. The most viable option to solve this is by means of a high‐power electron beam fired from a magnetospheric spacecraft and spotted at its magnetic footpoint in the ionosphere. This has technical difficulties. Progress has been made on mitigating the major issue of spacecraft charging. The remaining physics issues are identified, together with the need for a synergistic effort in modeling, laboratory experiments, and, ultimately, testing in space. The goal of this commentary is to stimulate awareness and interest on the magnetosphere‐ionosphere connectivity problem and possibly accelerate progress toward its solution.
An abrupt shift in the Labrador Current System in relation to winter NAO events

Published: June 2016

AbstractThe behavior of the Labrador Current during the period from 1990 to 2007 is investigated with an eddy‐resolving circulation model for the North Atlantic Ocean. An EOF analysis of the model output suggests that the variability in the Labrador Current can be partitioned into a western Labrador Current (WLC; from the 300–2500 m isobaths), and an eastern Labrador Current (ELC; from the 2500 to 3300 m isobaths). The model results demonstrate that the WLC transport experienced an abrupt increase during 2000–2002, consistent with data. This differed significantly from the ELC transport which was strong during the high winter NAO (North Atlantic Oscillation) years (1990–1995) and then steadily declined. This ELC trend is consistent with changes in the modeled Atlantic Meridional Overturning Circulation and convection depth. Our study proposes that the change in the WLC is due to a southwestward shift of the atmospheric circulation pattern starting in 2001, coincident with a change in the 2001 NAO index, and also in a westward shift of the action centers of the winter NAO events.
Anomalous propagation conditions over eastern Pacific Ocean derived from MAGIC data
Authors: Alappattu Denny P. , Wang Qing , Kalogiros John 
Published: June 2016

AbstractThis study characterizes the evaporation and elevated ducts, the most common types of ducts observed over the ocean, along a track of around 4000 km between the California coast and Hawaii. We analyzed 1 year (2012–2013) of ship‐based measurements made during the Marine Atmospheric Radiation Measurement GPCI (GEWEX cloud system study Pacific Cross‐Section Intercomparison) Investigation of Clouds (MAGIC) campaign. During this period, the ship made multiple transects between Southern California and Hawaii. While the ship‐based in situ measurements and the radiosonde data served as the primary data source, a marine atmospheric surface layer model adapted from the Coupled Ocean‐Atmosphere Response Experiment 3.0 surface flux scheme is used to diagnose evaporative duct properties. Calculated mean evaporation duct heights based on shipboard measurements were found to increase steadily from 7 m offshore California to about 15 m near Hawaii. Overall 78% of duct heights are below 20 m. On average the evaporation duct strength is between ≈ 25 and 35 M units near Hawaii and about 15 M units near the California coast. A gradual transition from stratocumulus (Sc) dominated offshore California to trade wind regime with cumulus (Cu) clouds takes place along MAGIC track. The measured marine atmospheric boundary layer (MABL) height and the capping inversion characteristics are significantly different in the two regimes with MABL decoupling occurring in the longitude range between 125°W and 140°W along the track. The characteristics of the elevated ducts, obtained from the rawinsonde sounding profiles, are also different in the two regions west and east of the MABL decoupling region. Approximately 70–80% of the elevated ducts occur below 1.5 km east of the decoupling region, whereas almost equal percentage of ducts forms at heights above 1.5 km on the west side.
Numerical research on clear imaging of azimuth‐traveling ocean waves in SAR images
Authors: Yoshida Takero 
Published: June 2016

AbstractThis paper presents the imaging mechanisms of ocean waves traveling in the azimuth direction by applying a numerical simulation of synthetic aperture radar (SAR) image for moving ocean surfaces. The numerical simulation was originally designed in the time domain to take into account motion‐induced modulations. It is known that azimuthal waves are affected by azimuth shifts due to orbital motions of ocean waves, i.e., velocity bunching. The effect of bunching generally results in nonlinear imaging; however, a clear wavelike pattern of a homogeneous wave field propagating to the azimuth direction occurs in SAR imagery under a certain condition. More specifically, if azimuth shifts due to the orbital motions are concentrated on wave crests or troughs, bunching causes a single peak in SAR image planes. Theoretically, it is derived noticeably when the maximum orbital motion of an azimuth‐traveling ocean wave is nearly equal to one quarter of its wavelength. To demonstrate this, SAR signals were simulated numerically for ocean waves with and without employing the condition of the clear imaging. The results showed that a wavelike pattern relating to the azimuthal waves can be imaged apparently under the specific condition. In addition, the simulations were performed in the case of the other wave and wind conditions. From the results, it was revealed that the specific condition leads to clear wavelike imaging of azimuthal waves in SAR images if noise is relatively small.
State‐of‐the‐art research on electromagnetic information security
Authors: Hayashi Yu‐ichi 
Published: June 2016

AbstractAs information security is becoming increasingly significant, security at the hardware level is as important as in networks and applications. In recent years, instrumentation has become cheaper and more precise, computation has become faster, and capacities have increased. With these advancements, the threat of advanced attacks that were considerably difficult to carry out previously has increased not only in military and diplomatic fields but also in general‐purpose manufactured devices. This paper focuses on the problem of the security limitations concerning electromagnetic waves (electromagnetic information security) that has rendered attack detection particularly difficult at the hardware level. In addition to reviewing the mechanisms of these information leaks and countermeasures, this paper also presents the latest research trends and standards.

AbstractObjectivesThere is a major ascertainment bias in microbiome research, with individuals of predominately European ancestry living within metropolitan areas dominating most studies. Here we present a study of the salivary microbiome within a North American Indian community. This research is the culmination of four years of collaboration and community engagement with Cheyenne & Arapaho (C&A) tribal members from western Oklahoma.Materials and MethodsUsing 16S rRNA gene amplification and next‐generation sequencing, we generated microbial taxonomic inventories for 37 individuals representing five towns within the C&A tribes. For comparison, we performed the same laboratory techniques on saliva samples from 20 non‐native individuals (NNI) from Norman, Oklahoma.ResultsThe C&A participants differ from the NNI in having reduced within‐individual species richness and higher between‐individual variation. Unsupervised clustering analyses reveal that three ecological groupings best fit the data, and while C&A individuals include assignments to all three groups, the NNI individuals are assigned to only one group. One of the ecological groups found exclusively among C&A participants was characterized by high abundance of the oral bacterial genus Prevotella.DiscussionThe C&A and NNI participants from Oklahoma have notable differences in their microbiome diversity, with a wider range of variation observed among the C&A individuals, including a higher frequency of bacteria implicated in systemic disorders. Overall, this study highlights the importance of engagement with indigenous communities, and the need for an improved understanding of human microbiome diversity among underrepresented groups and those individuals living outside of metropolitan areas.
