Shear rate induced viscosity change of human blood samples and blood mimicking fluids
Authors: Szabó Eszter , Baka Ernő Z. , Tamás Kornél 
Published: July 2024

Purpose
The aim of this study was to measure blood and blood mimicking fluids viscosity at different shear rates (on the interval of 0.1-5000 1/s and 0.1-10000 1/s) while taking into consideration the measuring device’s capability and blood’s characteristics. We also provided the measurement results of the most accurate measuring program.
Methods
We measured blood samples from five donors, and four different blood mimicking fluid compositions. The measurements were done on an Anton Paar Physica MCR301 rotational rheometer with two measuring programs varying in the shear rate intervals, the number of measuring points and the measuring point durations.
Results
The results confirmed the significant shear thinning and thixotropic effects of blood. Blood mimicking fluids also had these characteristics. The measured blood viscosity values are in agreement with those of the literature.
Conclusions
It can be concluded that the step test program was able to give more stable results as the measured torque was over the nominal limit of 0.05 μNm over 0.1 1/s and over the selected torque limit of 0.5 μNm over 31.6 1/s. Blood mimicking fluid measurement results were different from that of the literature due to different measuring conditions. The sample consisting of water, glycerol and starch mimicked well blood’s behaviour and viscosity values at 37 degrees Celsius.

Maquetando una genealogía de lo universal en lo gráfico: de Comenius a Nadia Hafid, pasando por Otto Neurath
Authors: García López Óscar 
Published: July 2024

La aspiración a la universalidad que atravesó las corrientes científicas, los movimientos sociales y las tendencias culturales durante la modernidad ilustrada ha sufrido una decadencia comprensible en las últimas décadas. Pero antes de la Segunda Guerra Mundial, cuando todavía su consideración seguía al alza y era posible imaginar la adopción del esperanto como un idioma auxiliar internacional, el filósofo austriaco Otto Neurath abordó un proyecto similar partiendo de la representación visual. Su sistema ISOTYPE anhelaba convertirse en un lenguaje gráfico cuya comprensión resultara independiente de la nacionalidad o el idioma hablado por quien observara sus signos. En ese sentido, Neurath no pretendía alcanzar una universalidad respecto al potencial de representación, que él mismo reconoce en desventaja frente a lo verbal, sino en su uso. El imposible afán que lo guiaba era el de consumar la desbabelización, pretexto latente en muchos otros intentos de establecer un lenguaje universal.
Los principios de diseño y organización en las imágenes que Neurath creó junto a Marie Neurath y al artista gráfico Gerd Arntz se pueden identificar en las poéticas que guían el trabajo de algunos autores de cómic actuales que, aunque probablemente no incluirían la categoría de lo universal entre los principios impulsores de sus obras, en el tratamiento que llevan a cabo de los códigos del cómic, indirectamente, avanzan en esa misma dirección. Esta intuición puede llevarnos a valorar si el sistema semiótico del cómic, a día de hoy integrado en un acervo cultural globalizado, se ha ido aproximando a la meta que se propuso Neurath e incluso ha podido superarla gracias a la conjunción de lo gráfico y lo verbal, que amplía sus posibilidades de representación.
En este texto se pretende bosquejar una genealogía de lo universal en lo gráfico, tomando a Neurath como origen de coordenadas para proyectarnos hacia el pasado, hasta la figura de John Amos Comenius, y hacia el futuro, hasta un grupo de autores españoles actuales, que profesan una poética del cómic en la que se pueden identificar ciertos rasgos de esa corriente subyacente de universalidad, y entre los que se puede mencionar a Nadia Hafid, Antonio Hitos, Conxita Herrero, Lorenzo Montatore o Max. Este itinerario permitirá la reflexión sobre la naturaleza del signo icónico, su consideración como lenguaje o sistema de códigos y su valor como instrumento de comunicación y educación.

Комплексная оценка образцов коллекции по таким агрономическим признакам, как продуктивность, сахаристость, сбор сахара, устойчивость к основным болезням, позволили выделить ценный исходный материал для вовлечения в селекционные программы. В результате изучения селекционного материала проведена сравнительная оценка морфологических признаков 15 МС-компонентов и 10 гетерозисных опылителей для определения наиболее влиятельных признаков растений на продуктивность.
Установлено, что изученные материалы различаются по характеру изменчивости основных элементов продуктивности (форма, масса корнеплода, содержание сахара, устойчивости к болезням и др.). Из изучаемых МС номеров по урожайности выделены 5 лучших номеров (2076, 2084, 2172, 2190, 2192), по сахаристости 4 номера (2084, 2174, 2076, 2190).
В результате проведенных исследований выявлено, что в селекционных номерах сахарной свеклы встречаются растения с различной листовой пластинкой, длиной черешков. Листья встречаются, как гладкие, так и гофрированные в различной степени, темно- и светло-зеленые, с различным количеством листьев, раскидистые и прямостоячие, высокие и низкие. В опылителях О-типа количество раскидистых растений оказывает высокую положительную зависимость на продуктивные показатели. Количество высоких растений в номере отвечает за более высокую урожайность, сахаристость. Растения с большой листовой пластинкой среди МС линий обладают меньшей урожайностью, но повышенной сахаристостью. В период вегетации и уборки свеклы проводился отбор растений по морфологическим признакам листового аппарата, форме розетки и корнеплода в количестве 50-60% от общего числа растений на делянке в зависимости от наличия желательных биотипов.

Abstract
Low-surface-brightness (LSB) galaxies play a crucial role in our understanding of galaxy evolution and dark matter cosmology. However, efficiently detecting them in large-scale surveys is challenging, due to their dim appearance. In this study, we propose a two-step detection method based on deep learning to address this issue. First, an object detection model called GalCenterNet was designed to detect LSB galaxy candidates in astronomical images. The model was trained using a data set of 665 Sloan Digital Sky Survey (SDSS) images, which contained 667 LSB galaxies. On the test set, the model achieved an accuracy of 95.05% and a recall of 96.00%. Next, an anomaly detection technique known as Deep Support Vector Data Description was applied to identify abnormal sources, thus refining the LSB candidates. By applying the two-step detection method to SDSS images, we have obtained a sample of 37,536 LSB galaxy candidates. This wide-area sample contains diverse and abundant LSB galaxies, which are valuable for studying the properties of LSB galaxies and the role that the environment plays in their evolution. The proposed detection method enables end-to-end detection from the SDSS images to the final detection results. This approach will be further employed to efficiently identify objects in the upcoming Chinese Survey Space Telescope sky survey.

Abstract
We present an analysis of high-angular-resolution images of the microlensing target MOA-2007-BLG-192 using Keck adaptive optics and the Hubble Space Telescope. The planetary host star is robustly detected as it separates from the background source star in nearly all of the Keck and Hubble data. The amplitude and direction of the lens–source separation allows us to break a degeneracy related to the microlensing parallax and source radius crossing time. Thus, we are able to reduce the number of possible binary-lens solutions by a factor of ∼2, demonstrating the power of high-angular-resolution follow-up imaging for events with sparse light-curve coverage. Following Bennett et al., we apply constraints from the high-resolution imaging on the light-curve modeling to find host star and planet masses of M

Abstract
We empirically assess estimates from v3.0 of the James Webb Space Telescope
NIRCam Exposure Time Calculator (ETC) using observations of resolved stars in
Local Group targets taken as part of the Resolved Stellar Populations Early
Release Science (ERS) Program. For bright stars, we find that (i) purely
Poissonian estimates of the signal-to-noise ratio (SNR) are in good agreement
between the ETC and observations, but nonideal effects (e.g., flat-field
uncertainties) are the current limiting factor in the photometric precision that
can be achieved; (ii) source position offsets, relative to the detector pixels,
have a large impact on the ETC saturation predictions and introducing subpixel
dithers in the observation design can improve the saturation limits by up to ∼1
mag. For faint stars, for which the sky dominates the error budget, we find that
the choice in the ETC extraction strategy (e.g., aperture size relative to
point-spread function size) can affect the exposure time estimates by up to a
factor of 5. We provide guidelines for configuring the ETC aperture photometry
to produce SNR predictions in line with the ERS data. Finally, we quantify the
effects of crowding on the SNRs over a large dynamic range in stellar density
and provide guidelines for approximating the effects of crowding on SNRs
predicted by the ETC.

Published: July 2024

Abstract
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has obtained more than 23 million spectra, opening an unprecedented opportunity to study stellar physics, as well as the formation and evolution of our Milky Way. In order to obtain the accurate stellar parameters, we develop a LAMOST Medium-Resolution Spectral Analysis Pipeline (LAMA), which estimates the stellar parameters from the LAMOST medium-resolution spectra, including the effective temperature (T
eff), surface gravity (

log
g

), metallicity ([Fe/H]), radial velocity, and rotational velocity (

v
sin
i

). LAMA estimates these parameters utilizing the template-matching method. The comparison between our results and those from the high-resolution ones, including APOGEE, GALAH, and PASTEL, shows no obvious bias, indicating the reliability of our results. The accuracy of T
eff and [Fe/H] can reach 75 K and 0.12 dex, respectively, for the LAMOST Medium-Resolution Spectroscopic Survey (MRS) spectra with a signal-to-noise ratio higher than 10. For dwarfs, the uncertainty of

log
g

is around 0.17 dex, while, for giants, it ranges from 0.18 to 0.30 dex, with the errors decreasing as

log
g

increases. Using LAMA for the LAMOST-MRS spectra, we estimate the stellar parameters of 497,412 stars. This sample will be very helpful for investigating the formation and evolution of our Galaxy.

Abstract
The Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) images and their derived products make up one of the highest-resolution and most spatially accurate data sets available for the Moon, making them a crucial resource for planners of landed lunar missions. However, it is essential to understand the best uses for each data type and the limits on the accuracy and resolution of the data sets available. With this understanding, users can better interpret and communicate their results. In this paper, we describe what assumptions may be made about the accuracy of LROC NAC images and the various derived products created by the LROC team. NAC digital terrain models and their corresponding orthophotos have the best accuracy of all NAC products, usually better than 10 m horizontally, and should be used where available. Other controlled NAC products usually have accuracies better than 30 m. For areas without controlled products, we describe how to process NAC images to obtain coordinates with the highest possible accuracy. We also recommend best practices for data users interacting with LROC data through online map servers, such as QuickMap or Lunaserv, and for processing LROC data locally using the US Geological Survey Integrated Software for Imagers and Spectrometers.

ObjectiveThe main aim of the study was to evaluate the performance of 2 proposed criteria for difficult-to-treat (D2T) psoriatic arthritis (PsA) in a group of patients and to evaluate the agreement between the 2 sets of criteria.MethodsWe performed a cross-sectional analysis of 2 longitudinal cohorts of patients with PsA fulfilling the Classification Criteria for Psoriatic Arthritis (CASPAR), with at least 1 year of follow-up. A detailed medical history was collected and a physical examination was performed for all recruited patients. The proposed criteria for patients with D2T PsA were applied in our group. To test the performance of the 2 sets of criteria, we used an external validator (absence of patient acceptable symptom state + physician global assessment ≥ 6 cm). Finally, the agreement between the 2 sets of criteria was assessed.ResultsWe evaluated 378 patients with PsA (219 male/159 female), with a mean age (range) of 58 (19-75) years. Seventy-five (19.8%) patients fulfilled the D2T criteria proposed by Perrotta et al and 58 (15.3%) the D2T criteria proposed by Kumthekar et al. Both criteria showed comparable performance, with low sensitivity (Perrotta: 37.8%, Kumthekar: 29.7%) but good specificity (Perrotta: 82.1%, Kumthekar: 86.2%). Finally, the agreement between the 2 sets of criteria is substantial (Fleiss0.72), suggesting that both criteria identify nearly the same group of patients.ConclusionOur study compared 2 published sets of criteria showing comparable performance and substantial agreement. This study may pave the way for further research in this field.
Une démocratie irrégulière ? Sur la dénonciation des fraudes électorales aux États-Unis
Authors: Ihl Olivier 
Published: July 2024

Depuis une vingtaine d’années, l’instrumentalisation du thème de la fraude électorale scande la vie politique aux États-Unis. Elle exacerbe la polarisation de l’électorat et érode la confiance dans l’intégrité des scrutins. Cet article interroge le soubassement historique et politique de cette mobilisation qui, élection après élection, a pris une ampleur inégalée. Que recouvre le défi consistant pour les deux grands partis à prétendre réguler des atteintes au droit de suffrage ? Ces stratégies peuvent au besoin se nourrir de croyance et de désinformation. Reste qu’elles relèvent d’un réformisme partisan, c’est-à-dire, de revendications longuement mûries pour changer les règles du jeu au profit de l’intérêt immédiat de chaque parti. Au risque de dresser la performance électorale contre l’intérêt public, la victoire dans les urnes contre l’État de droit.
Terroirs communs et dynamiques agraires : une analyse comparée de l’histoire agraire récente du Burkina Faso, de l’Équateur et de l’Inde
Authors: Bainville Sébastien , Aubron Claire , Philippon Olivier 
Published: July 2024

Cet article vise à réhabiliter les « vieux » concepts de la géographie rurale que sont les finages et les terroirs. Bien qu’anciens, ils n’en sont pas devenus désuets pour autant et s’avèrent extrêmement utiles pour saisir la place des communs fonciers dans les dynamiques agraires contemporaines. Par leur dimension à la fois technique et socio-économique ils permettent de dépasser l’opposition trop simple entre le collectif et le privé pour traiter des questions foncières. Ces concepts ont été mobilisés dans le cadre de recherches menées au cours des vingt dernières années dans des contextes variés : sud-ouest du Burkina Faso, nord des Andes équatoriennes, ouest et sud de l’Inde. Au-delà de leurs particularités, ces régions ont pour point commun d’avoir connu au cours de leur histoire récente une organisation des finages agricoles suivant le modèle ager - saltus-silva . L’analyse de ces situations tropicales contemporaines fournit de nouveaux éléments sur l’origine et la disparition de ce type de finages. Surtout, cette recherche comparative invite à repenser le rôle des terroirs d’usage commun dans les dynamiques agraires. Loin d’être de simples compléments, les communs se sont révélés indispensables à la constitution de terroirs « privés ». Il en résulte que contrairement au rôle redistributif qu’on leur attribue souvent ils ont été au cœur des processus de domination, de différenciation et d’exclusion au sein du monde paysan. Depuis la révolution verte, ils sont devenus des zones refuges pour les exclus de l’intensification ou des réserves écologiques où toute activité agricole est proscrite.
Le rôle des proximités au sein d’un réseau d’acteurs territorialisé dans l’émergence et la gestion d’un commun : le cas d’une expérimentation « Territoires zéro chômeur de longue durée »
Authors: Retsin Camille , Petrella Francesca 
Published: July 2024

Partant de l’hypothèse selon laquelle l’expérimentation « Territoires zéro chômeur de longue durée » peut être étudiée sous le prisme des communs, notre objectif est d’abord de comprendre en quoi TZC pourrait être un commun dans son essence pour ensuite analyser au niveau territorial comment les proximités créées, entretenues ou renforcées au sein d’un réseau d’acteurs coopérant peuvent faciliter – ou non – la construction et la gestion de ce commun dans le temps. Croiser l’analyse des communs et celle des proximités permet de questionner le processus de construction d’une action collective à partir de la coopération entre acteurs hétérogènes et de l’adoption d’un système de règles et de normes partagé autour de la gestion d’un commun sur le territoire. À partir d’une étude de cas longitudinale sur l’un des dix premiers territoires expérimentaux, notre travail met, entre autres, en exergue la manière dont le manque de proximité institutionnelle entre les acteurs (compris comme le manque de valeurs partagées) vient entraver la gestion de l’expérimentation comme un commun.
