Ultra-processed food consumption and the risk of non-alcoholic fatty liver disease—What are the proposed mechanisms?
Authors: Hägele Franziska A. , Enderle Janna , Rimbach Gerald , Bosy-Westphal Anja
Published: August 2023

A high consumption of ultra-processed food (UPF) is a hallmark of Western diets that has been related to increased risk of non-communicable diseases. As an underlying mechanism, UPF may promote non-alcoholic fatty liver disease (NAFLD) which is a key driver of metabolic impairment with extra-hepatic manifestations like type 2 diabetes, cardiovascular disease, chronic kidney disease, and osteoporosis among others. The present review provides an overview of UPF properties that may promote NAFLD and are thus potential targets for reformulation of UPF. Such approaches should address improvements in the quality of carbohydrates and fat, changes in food texture that lower eating rate as well as ingredients that prevent excess caloric intake or avoid dysbiosis and leaky gut syndrome. Promising strategies are enrichment with fiber, prebiotics, phytochemicals, and protein with a concurrent reduction in glycemic load, energy density, saturated fatty acids (FA; SFA), emulsifiers, fructose, and non-caloric sweeteners. Future studies are needed to examine the interactive and protective effects of such modifications in the composition of UPF on prevention and treatment of NAFLD.

Resolving conflict between aversive and appetitive learning of views: how ants shift to a new route during navigation
Authors: Lionetti Vito A. G. , Deeti Sudhakar , Murray Trevor , Cheng Ken
Published: August 2023

Ants store and recall views associated with foraging success, facilitating future foraging journeys. Negative views are also learned, but instead prompt avoidance behaviors such as turning away. However, little is known about the aversive view’s role in navigation, the effect of cue conflict, or the contextual relationship between learning and recalling. In this study, we tested Myrmecia midas’ capacity for aversive learning of views either independently of or in conflict with appetitive events. We either captured and released foragers when reaching a location or let them pass unhindered. After a few journeys, captured foragers exhibited aversive learning by circumventing the capture location and increasing both meandering and scanning. Ants that experienced foraging-appetitive and homing-aversive events on their journeys exhibited lower rates of avoidance behavior and scans than those experiencing aversive events in both outbound and homebound journeys. The foraging-aversive and homing-aversive ants exhibited similar levels of avoidance and scanning as those that experienced the foraging-aversive and homing-appetitive. We found that foragers showed evidence of context specificity in their scanning behavior, but not in other measures of aversive learning. The foragers did not increase their meandering and scans while approaching the views associated with aversive events. In addition to shedding light on the role of aversive views in navigation, our finding has important implications for understanding the learning mechanisms triggered by handling animals.
The Stroop legacy: A cautionary tale on methodological issues and a proposed spatial solution
Authors: Viviani Giada , Visalli Antonino , Montefinese Maria , Vallesi Antonino , Ambrosini Ettore
Published: August 2023

The Stroop task is a seminal paradigm in experimental psychology, so much that various variants of the classical color–word version have been proposed. Here we offer a methodological review of them to emphasize the importance of designing methodologically rigorous Stroop tasks. This is not an end by itself, but it is fundamental to achieve adequate measurement validity, which is currently hindered by methodological heterogeneity and limitations. Among the several Stroop task variants in the literature, our methodological overview shows that the spatial Stroop task is not only a potentially methodologically adequate variant, which can thus assure measuring the Stroop effect with the required validity, but it might even allow researchers to overcome some of the methodological limitations of the classical paradigm due to its use of verbal stimuli. We thus focused on the spatial Stroop tasks in the literature to verify whether they really exploit such inherent potentiality. However, we show that this was generally not the case because only a few of them (1) are purely spatial, (2) ensure both all the three types of conflicts/facilitations (at the stimulus, response, and task levels) and the dimensional overlaps considered fundamental for yielding a complete Stroop effect according to the multiple loci account and Kornblum’s theory, respectively, and (3) controlled for low-level binding and priming effects that could bias the estimated Stroop effect. Based on these methodological considerations, we present some examples of spatial Stroop tasks that, in our view, satisfy such requirements and, thus, ensure producing complete Stroop effects.
Multigene phylogeny of the order Physarales (Myxomycetes, Amoebozoa): shedding light on the dark-spored clade
Authors: García-Martín J.M. , Zamora J.C. , Lado C.
Published: August 2023

The class Myxomycetes consists of free-living protists characterised by their complex life cycle, which includes both microscopic (amoebae, flagellates and cists) and macroscopic stages (spore-bearing fruiting bodies, sclerotia, andplasmodia). Withinit, theorder Physarales,
with more than 450 recognised species, constitutes the largest group. Although previous studies have shown the polyphyly of some of the traditionally accepted genera, its internal phylogenetic relationships have remained uncertain so far, and together with the lack of data for some keyspecies,
itprevented any taxonomic and nomenclatural revisions. We have compiled a substantially expanded data setinterms of both taxon sampling and molecular data, including most of the genera described to date and four unlinked DNA regions, for which we provide partial sequences: nSSU, EF-1α
, α-Tub, and mtSSU, analysed through maximum likelihood and Bayesian methods. Our results confirm that the family Didymiaceae is paraphyletic to the rest of Physarales. Within Didymiaceae s. lat., the recent reinstatement of the genus Polyschismium
for most species traditionally ascribed to Lepidoderma, except for the type (Ronikieretal.2022), is further supported here, as well as the definite inclusion of the genus Mucilago in Didymium and Lepidoderma s. str.(L. tigrinum) in Diderma
(Prikhodkoetal.2023). Additionally, thegenus Diachea is redefined to include some species previously treated in Physaraceae (Craterium spp. with true columella). Within the monophyletic family Physaraceae, most genera are recovered as polyphyletic, suggesting that
they should be no longer accepted as currently defined. However, the lack of resolution of some relationships within Physaraceae prevents us from resuscitating or creating several new genera to mitigate polyphyly. Among the well-defined groups with clear molecular signatures, we propose
two taxonomic and nomenclatural changes at generic level:1) a new genus, Nannengaella, is proposed for a major clade containing Physarum globuliferum and other species with heavily calcified sporophores and, often, a true calcareous columella;2) Lignydium is resurrected
for the clade containing Fuligo muscorum. Additionally, Trichamphora is suggested as the correct name for the clade containing Physarum pezizoideum. The taxonomy and nomenclature of some provisional genera, currently synonymous with Fuligo and Physarum, are
disentangled, and we provide a comprehensive and updated nomenclatural conspectus that can be used when better resolved phylogenies are obtained. In total, 22 new combinations are proposed in different genera. Aprovisional key to the genera of the order is also provided.
Determination of Organic and Reduced Inorganic Sulfur by Multi-element Scanning Thermal Analysis
Authors: Hsieh Yuch-Ping , C Bugna Glynnis
Published: August 2023

Determination of organic sulfur in solid environmental samples has been difficult because there is no appropriate separation technology. Routine organic sulfur analysis has mostly been done indirectly by the difference between the total and the inorganic sulfur contents. This indirect analysis is tedious, accumulating multiple sampling and procedural errors, and has no chemical characterization information. There are modern technologies such as S-XANES for direct sulfur analysis on solid samples. But they are sophisticated, expensive, and unavailable for routine sulfur analysis. Due to those analytical difficulties, our understanding of sulfur chemistry in solid samples has been limited. This study was initiated to apply a convenient Multi-Element Scanning Thermal Analysis (MESTA) method for direct analysis of organic and reduced inorganic sulfur in solid samples. If successful, sulfur MESTA will be a convenient and powerful tool for studying environmental sulfur cycles and sulfur-containing materials. We used 27 reference organic and reduced inorganic sulfur compounds to validate the MESTA method. The results indicate that MESTA can directly quantify and characterize organic and reduced inorganic sulfur compounds. Recoveries of the reference compounds were in the range of 77.0% to 97.7% except for sulfate functional group containing compounds of bathophenanthrolinedisulfonic acid (57.4 ± 6.7%), sodium thiosulfate (60.6 ± 3.1%) and sodium dodecyl sulfate (38.0 ± 2.6%). MESTA is rapid, sensitive, and inexpensive. It is a convenient and powerful tool for sulfur analysis in a wide range of solid, liquid, or mixed samples.

Published: August 2023

Background: Mycotoxins are secondary fungal metabolites that are produced in rice, corn, nuts and several other cereals. The contamination of food stuff by mycotoxins is a cause of numerous diseases throughout the world. Aflatoxins are potent mycotoxins that have chronic and acute toxicity.

Objectives: To evaluate the presence of aflatoxins B1, B2, G1 and G2 in branded and non-branded rice varieties available in Punjab, Pakistan.

Methodology: Total 150 rice samples were collected in May 2019 from various cities (Islamabad, Rawalpindi, Gujar Khan, Jehlum, Kharian, Gujrat, Gujranwala, Lahore, Kasur, Okara, Sahiwal, Mian Channu, Khanewal, Multan, Bahawalpur and Rahim Yar Khan) of Pakistan. All the rice samples were subjected to physical testing methods, followed by extraction (using chloroform extraction method) and qualitative and quantitative detection of aflatoxin using Thin layer Chromatography (TLC) Technique and Enzyme linked Immunosorbent assay (ELISA).

Results: No aflatoxins was detected in branded rice varieties which were stored in good packaging. The aflatoxin B1 (AFB1) was detected in 65% of poorly stored rice varieties, with maximum contamination of 8.92ppb. The lowest moisture 9.4% content was found in (branded samples) and 10.9% (non-branded samples) while highest moisture content 10.8% found in (branded samples) and 16% found in (non-branded samples). The 54 out 100 non-branded samples found to have more than 13% moisture contents which is alarming.

Conclusion: With the implementation of effective strategies and special precautions during storage, harvesting, transportation, drying and harvesting, we can prevent the contamination of rice product with fungi and stop aflatoxin production which is a major threat to country economy.

Published: August 2023

Using panel data from 269 Chinese cities, this study examined the impact of housing prices (HP) on cities’ innovation capacity (IC) in China. Firstly, a fixed effect model was used to analyze the effect of HP on cities’ IC in China, revealing that HP positively impacts cities’ IC. Next, several robustness tests were conducted to verify the finding’s reliability. Thirdly, the analysis empirically tested mediating mechanisms between HP and cities’ IC in China. The results show that, on the one hand, higher HP can improve cities’ IC by attracting talents and stimulating the growth of local fiscal revenue. On the other, increasing HP can inhibit cities’ IC in China by attracting funds into the real estate market and impeding residents’ consumption ability. Finally, the heterogeneous nature of the HP–IC link in China was further explored. This study’s results provide recommendations for the government of China on how to promote cities’ innovation performance.
MFPIM: A Deep Learning Model Based on Multimodal Fusion Technology for Pulsar Identification
Authors: Liu Yi , Jin Jing , Zhao Hongyang , He Xujie , Guo Yanan
Published: August 2023

With the development of radio telescope technology, the quantity and types of acquired pulsar candidate data have increased dramatically. However, it is difficult to accurately identify pulsar candidates. Therefore, we propose to use multimodal fusion technology, called the multimodal fusion-based pulsar identification model (MFPIM), to build a deep learning model to improve the efficiency and accuracy of pulsar candidate identification. MFPIM treats each diagnostic plot of pulsar candidates as a modality and uses multiple convolutional neural networks to extract effective features from the diagnostic plots. After fusing the features, the commonality of different modalities in high-dimensional space is obtained to ensure that the model can take full advantage of the complementarity between diagnostic plots and thus identify pulsar candidates, achieved better classification performance than other current supervised learning algorithms. In addition, a channel attention mechanism is used in the model to enable it to learn the importance of different channel features so that the model focuses more on the channel information in the input data that is more meaningful for classification, reducing the model size while extracting pulsar diagnostic map features more accurately. We conducted experiments on the Five-hundred-meter Aperture Spherical radio Telescope (FAST) data set, and the results show that MFPIM can effectively identify the pulsars in the FAST data set with an identification accuracy of over 98%. To further verify the robustness of the model, we applied the MFPIM to the High Time Resolution Universe data set using transfer learning, with the test accuracy and F1 score reaching over 99%.
Efficiency of Magnetohydrodynamic Wave Generation in Weakly Ionized Atmospheres
Authors: Cally Paul S.
Published: August 2023

The generation of Alfvén and slow magnetoacoustic waves in weakly ionized atmospheres by excitation of the charges-only component of the two-fluid (charge and neutral) plasma is shown to be more or less efficient depending on the energy fraction initially allocated to the three stationary flow differential modes, which characterize the inter-species drift. This is explained via detailed analysis of the full 10-dimensional spectral description of two-fluid linear magnetohydrodynamics. Excitation via the velocity of the charges only is found to be very inefficient, in accord with previous results, while excitation via the magnetic field perturbation alone is highly efficient. All 10 eigenvalues and eigenvectors are presented analytically in the high collision frequency regime.
Comparative Analysis of TRGBs (CATs) from Unsupervised, Multi-halo-field Measurements: Contrast is Key

Published: August 2023

The tip of the red giant branch (TRGB) is an apparent discontinuity of the luminosity function (LF) due to the end of the red giant evolutionary phase and is used to measure distances in the local universe. In practice, tip localization via edge detection response (EDR) relies on several methods applied on a case-by-case basis. It is hard to evaluate how individual choices affect a distance estimation using only a single host field while also avoiding confirmation bias. To devise a standardized approach, we compare unsupervised, algorithmic analyses of the TRGB in multiple halo fields per galaxy. We first optimize methods for the lowest field-to-field dispersion, including spatial filtering, smoothing, and weighting of LF, color band selection, and tip selection based on the number of likely RGB stars and the ratio of stars below versus above the tip (R). We find R, which we call the tip contrast, to be the most important indicator of the quality of EDR measurements; higher R selection can decrease field-to-field dispersion. Further, since R is found to correlate with the age or metallicity of the stellar population based on theoretical modeling, it might result in a displacement of the detected tip magnitude. We find a tip-contrast relation with a slope of −0.023 ± 0.0046 mag/ratio, an ∼5σ result that can be used to correct these variations in the detections. When using TRGB to establish a distance ladder, consistent TRGB standardization using tip-contrast relation across rungs is vital to make robust cosmological measurements.
A Cross-internal Linear Combination Approach to Probe the Secondary CMB Anisotropies: Kinematic Sunyaev–Zel’dovich Effect and CMB Lensing
Authors: Raghunathan Srinivasan , Omori Yuuki
Published: August 2023

We propose a cross-internal linear combination (cross-ILC) approach to measure the small-scale cosmic microwave background (CMB) anisotropies robustly against the contamination from astrophysical signals. In particular, we focus on the mitigation of systematics from cosmic infrared background (CIB) and thermal Sunyaev–Zel’dovich (tSZ) signals in kinematic Sunyaev–Zel’dovich (kSZ) power spectrum and CMB lensing. We show the cross-spectrum measurement between two CMB maps created by nulling the contributions from CIB (CIB-free map) and tSZ (tSZ-free map) to be robust for kSZ, as the approach significantly suppresses the total contribution of CIB and tSZ signals. Similarly, for CMB lensing, we use the approach introduced by Madhavacheril & Hill but with a slight modification by using the tSZ-free and CIB-free maps in the two legs of the quadratic estimator. By cross-correlating the CMB lensing map created using this technique with galaxy surveys, we show that the biases from both CIB and tSZ are negligible. We also compute the impact of unmodeled CIB/tSZ residuals on kSZ and cosmological parameters, finding the kSZ measured using the standard ILC to be significantly biased. The kSZ estimate from the cross-ILC remains less affected by CIB/tSZ, making it crucial for current and upcoming CMB surveys such as the South Pole Telescope (SPT), Simons Observatory (SO), and CMB-S4. With the cross-ILC approach, we find that the total kSZ power spectrum can be measured at very high significance in the coming years: 35σ by SPT, 22σ by SO, and 80σ by CMB-S4. Finally, we forecast constraints on the epoch of reionization using the kSZ power spectrum and find that the duration of reionization, currently unconstrained by Planck, can be constrained to

We present here the results of 8 yr of our near-simultaneous optical–near-infrared spectro-photometric monitoring of the bona fide FU Ori (FUor)-type candidate V2493 Cygnus (V2493 Cyg) starting from 2013 September to 2021 June. During our optical monitoring period (between 2015 October 16 and 2019 December 30), the V2493 Cyg is slowly dimming with an average dimming rate of ∼26.6 ± 5.6 mmag yr−1 in the V band. Our optical photometric colors show a significant reddening of the source post the second outburst pointing toward a gradual expansion of the emitting region post the second outburst. The mid-infrared colors, on the contrary, exhibit a blueing trend, which can be attributed to the brightening of the disk due to the outburst. Our spectroscopic monitoring shows a dramatic variation of the Hα line as it transitioned from absorption feature to the emission feature and back. Such transition can possibly be explained by the variation in the wind structure in combination with accretion. Combining our time evolution spectra of the Ca ii infrared triplet lines with the previously published spectra of V2493 Cyg, we find that the accretion region has stabilized compared to the early days of the outburst. The evolution of the O i
λ7773 Å line also points toward the stabilization of the circumstellar disk post the second outburst.

We present the JWST Resolved Stellar Populations Early Release Science (ERS) program. We obtained 27.5 hr of NIRCam and NIRISS imaging of three targets in the Local Group (Milky Way globular cluster M92, ultrafaint dwarf galaxy Draco II, and star-forming dwarf galaxy WLM), which span factors of ∼105 in luminosity, ∼104 in distance, and ∼105 in surface brightness. We describe the survey strategy, scientific and technical goals, implementation details, present select NIRCam color–magnitude diagrams (CMDs), and validate the NIRCam exposure time calculator (ETC). Our CMDs are among the deepest in existence for each class of target. They touch the theoretical hydrogen-burning limit in M92 (<0.08 M
⊙; M
F090W ∼ +13.6), include the lowest-mass stars observed outside the Milky Way in Draco II (0.09 M
⊙; M
F090W ∼ +12.1), and reach ∼1.5 mag below the oldest main-sequence turnoff in WLM (M
F090W ∼ +4.6). The PARSEC stellar models provide a good qualitative match to the NIRCam CMDs, though they are ∼0.05 mag too blue compared to M92 F090W − F150W data. Our CMDs show detector-dependent color offsets ranging from ∼0.02 mag in F090W – F150W to ∼0.1 mag in F277W – F444W; these appear to be due to differences in the zero-point calibrations among the detectors. The NIRCam ETC (v2.0) matches the signal-to-noise ratios based on photon noise in uncrowded fields, but the ETC may not be accurate in more crowded fields, similar to what is known for the Hubble Space Telescope. We release the point-source photometry package DOLPHOT, optimized for NIRCam and NIRISS, for the community.
A Catalog of New Slowly Pulsating B-type Stars
Authors: Shi Xiang-dong , Qian Sheng-bang , Zhu Li-ying , Li Lin-jia
Published: August 2023

This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have found 286 new slowly pulsating B-type (SPB) stars and 21 candidates. Among these, 20 are Be stars or candidates with emission-line profiles. It is shown that these SPB stars have luminosities between 40 and 2850 L
⊙ and effective temperatures ranging from 10,000 to 21,000 K. Their pulsation periods are from 0.14 to 6.5 days with amplitude ranges of 0.2–20 mmag in the TESS band. It is indicated that these targets follow the distribution of the SPB stars in the period–luminosity and the period–temperature diagrams. Their positions on the H-R diagram reveal that most of these pulsators are distributed in the instability region of SPB stars, in the main-sequence evolutionary stage, and with mass ranges of 2.5–7 M
⊙. However, there are some targets beyond the red edge of the theoretical instability region, which should be caused by the rapid rotation reducing the measured effective temperature. The discovery of these new SPB stars increases the total number by over 60%, which are significant samples for further investigating the structure and evolution of intermediate-mass and even massive stars by asteroseismology.

Authors: Guler Alis Meryem , Alis Abdulkadir , Kucuk Abdulkadir , Acikalin Banu
Published: August 2023

Purpose:

To investigate the effect of strabismus surgery on choroidal structure using the binarization method.

Methods:

Forty-two eyes of 27 patients who had surgery for horizontal strabismus were included in the study. Optical coherence tomography (OCT) images of the patients before the operation and at 1 day and 1 week after the operation were binarized. Total choroidal area (TCA), stromal area (SA), luminal area (LA), and choroidal vascularity index (CVI) were calculated and compared.

Results:

The mean age of the patients was 16.7 ± 13.5 years; 12 were female, and 15 were male. The mean spherical equivalent was 0.125 ± 0.50 diopters (D). The mean axial length value was 23.3 ± 1.3 mm. Preoperative TCA was 599686 ± 113451, LA was 394259 ± 67259, SA was 209180 ± 47723, and CVI was 0.66 ± 0.02. At 1 day postoperatively, TCA was 615575 ± 103686, LA was 395364 ± 60314, SA was 218418 ± 45620, and CVI was 0.65 ± 0.02. At 1 week postoperatively, TCA was 610997 ± 110578, LA was 394002 ± 65186, SA was 214995 ± 46481, and CVI was 0.66 ± 0.04. A statistically significant decrease in CVI and increase in TCA and SA were observed on the first postoperative day; these changes were observed as returning to preoperative values at 1 week postoperatively.

Conclusions:

Strabismus surgery temporarily decreases the CVI by increasing the SA of the choroidal layer, possibly due to hemodynamic changes and/or inflammatory causes in the early period.

Published: August 2023

Statistical monitoring of the level of economic growth momentum transformation is the basis for implementing quantitative policies for economic growth transformation. Based on theoretical analysis and combined with the process of national economic operation, this paper designs an economic growth momentum transformation monitoring indicator system consisting of four dimensions, supply and demand, factors, consumption and trade, using a comprehensive evaluation method to compile the economic growth momentum transformation level index. Using mainland China's provincial data from 2002 to 2021, we calculated the economic growth momentum transformation level of each province and extracted corresponding characteristics. The research found that the economic growth momentum transformation level of provincial economies in China exhibits stage-wise and dimensional differentiation over time, and it has category agglomeration and tiered transfer characteristics in space.
The $ g $-extra $ H $-structure connectivity and $ g $-extra $ H $-substructure connectivity of hypercubes
Authors: Zhu Bo , Zhang Shumin , Ge Huifen , Ye Chengfu
Published: August 2023

At present, the reliability of interconnection networks of multiprocessing systems has become a hot topic of research concern for parallel computer systems. Conditional connectivity is an important parameter to measure the reliability of an interconnected network. In reality, the failure of one node will inevitably have a negative impact on the surrounding nodes. Often it is the specific structures that fail in an interconnected network. Therefore, we propose two novel kinds of connectivity, called $ g $-extra $ H $-structure connectivity and $ g $-extra $ H $-substructure connectivity, to go for a more accurate measure of the reliability of the network. Hypercube network is the most dominant interconnection network topology used by computer systems today, for example, the famous parallel computing systems Cray $ T3D $, Cray $ T3E $, $ IBM $ Blue Gene, etc. are built with it as the interconnection network topology. In this paper, we obtain the results of the $ g $-extra $ H $-structure connectivity and the $ g $-extra $ H $-substructure connectivity of the hypercubes when the specific structure is $ P_k $ and $ g = 1 $.

   \begin{document}$ \begin{align*} \left\{\begin{array}{rl} -\Delta_{\vec{p}}u(x)+\left(-\Delta\right)_{p}^{s}u(x) = \frac{f(x)}{u(x)^{\delta}}, &x\in\Omega, \\ u(x)>0, \; \; \; \; \; \; &x\in\Omega, \\ u(x) = 0, \; \; \; \; \; \; &x\in\mathbb{R}^{N}\setminus\Omega, \end{array} \right. \end{align*} $\end{document}

where $ \Omega $ is a bounded smooth domain of $ \mathbb{R}^{N}(N > 2) $, $ -\Delta_{\vec{p}}u $ is an anisotropic $ p $-Laplace operator, $ \vec{p} = (p_{1}, p_{2}, ..., p_{N}) $ with $ 2\leq p_{1}\leq p_{2}\leq\cdot\cdot\cdot\leq p_{N} $, $ \left(-\Delta \right)_{p}^{s} $ is the fractional $ p $-Laplace operator. The major results shows the interplay between the summability of the datum $ f(x) $ and the power exponent $ \delta $ in singular nonlinearities.
Igualibertad y paridad participativa: elementos básicos para democratizar la democracia
Authors: Valencia David Alejandro
Published: August 2023

En este artículo se propone un desarrollo esquemático del concepto de paridad participativa de Nancy Fraser como elemento complementario a la propuesta de democratizar la democracia de Étienne Balibar que se inscribe en la dialéctica de la igualibertad como marco de interpretación de la modernidad política. Se mostrará que el neoliberalismo implica un evento particular en el desarrollo de la lucha por la igualibertad anulando el contenido insurreccional de ésta y por tanto, dificultando una perspectiva democratizadora que, en la visión del autor francés, requiere recuperar la conflictividad política iniciada en la Revolución francesa en torno a la igualibertad. La paridad participativa, se argumentará, cumple los requisitos que exige la visión de Balibar y, la interpretación particular de la misma que se expondrá serviría como elementos básicos para democratizar la democracia.
El sorteo como dispositivo de la civilidad en Étienne Balibar
Authors: Beas Marín Pablo
Published: August 2023

En este artículo se exploran las aporías entre política y conflicto presentes en el pensamiento de Étienne Balibar. El texto explica, primero, cómo el conflicto es consustancial a la política y cómo, al mismo tiempo, un antagonismo excesivo puede imposibilitar la política sumiéndola en una espiral de violencia. En segundo lugar, el artículo muestra distintas estrategias para atemperar el antagonismo tales como el agonismo y la civilidad. Por último, en relación con este último concepto, se plantea la posibilidad de pensar el sorteo como un dispositivo de civilidad en cuanto que favorece una ruptura con el consenso posdemocrático y una atemperación de la violencia.
El tiempo de la insurrección: pasado, presente y futuro en Étienne Balibar
Authors: Garrido Violeta
Published: August 2023

Con el objetivo de contextualizar los aportes intelectuales más contemporáneos de Étienne Balibar, el presente artículo estudia la filosofía de la historia presente en su obra de madurez, es decir, la manera en la que el filósofo interpreta el cambio histórico en el campo político. En primer lugar, se aborda la significación relativamente benjaminiana que adquiere el «momento insurreccional» constitutivo del principio de la igualibertad, estableciendo los puntos de contacto y las diferencias entre la idea de Balibar y la de Benjamin. En un segundo momento, se rastrean los orígenes de dicha concepción del tiempo, que remiten a los trabajos tempranos elaborados junto a Althusser. Por último, y retomando algunos argumentos de la primera parte, se explica el sentido dialéctico del par ciudadanía/democracia y su relevancia en la actualidad.
Actualización filosófica del pensamiento de Albert Camus. Sísifo y Rieux, paradigmas de conducta para la contemporaneidad
Authors: Huertas Aguado Eloy
Published: August 2023

La muerte resulta problemática para la contemporaneidad. El existencialismo es una corriente filosófica que presenta la facticidad de la mortalidad como propia de la vida. El pensador Albert Camus articula los pilares fundamentales de su filosofía en torno a la experiencia de la muerte, que lleva al absurdo, del que debe partir la acción rebelde. En esta investigación se analizan algunas dinámicas que, pretendiendo huir de la muerte, solo han conseguido hacernos débiles frente a ella. Presentaremos a Sísifo y Rieux, dos de los personajes de sus escritos, como aquellos paradigmas de conducta que pueden contribuir a hacernos más conscientes del absurdo y poder, de este modo, vivir, amar y luchar.
La comunalidad indígena como respuesta al individualismo moderno
Authors: Anchondo Pavón Sandra , Gallardo Macip Cecilia
Published: August 2023

El objetivo de este artículo es mostrar cómo si bien el individualismo contemporáneo ha fragmentado los vínculos sociales de tal manera que pareciera imposible hablar de comunidades, el estudio de la comunalidad muestra de qué modo es posible concebir una sociedad donde el bien común sea el principal factor para resarcir la unión entre individuos, incluso en las sociedades liberales capitalistas. Se argumentará que, desde la modernidad, el auge del individuo sentó las bases del modo en que concebimos las relaciones sociales; sin embargo, la propuesta indígena nos muestra que hay otros caminos no hegemónicos que nos pueden ayudar a comprender a los sujetos como seres interdependientes y en sintonía con el mundo natural.
Évaluation du risque d’inondation par intégration du SAGA Wetness Index (SAGAWI) et de l’Analyse Hiérarchique des Procédés (AHP) : cas du District Autonome d’Abidjan
Authors: Traoré Kinakpefan Michel
Published: August 2023

Le District Autonome d’Abidjan (DAA) est en proie à une recrudescence des inondations. Ces évènements hydroclimatiques inhérents à la morphologie du site et à une expansion spatiale non maîtrisée sont susceptibles d’exaspération du fait des effets des changements globaux. Dans une perspective de gestion préventive des crises subséquentes, cette étude a pour objectif d’identifier les sous-espaces du District Autonome d’Abidjan les plus enclins aux risques d’inondation. L’approche cartographique intègre un indice topographique d’humidité en l’occurrence le SAGA Wetness Index et un indice d’imperméabilité des sols généré à partir de la normalisation des facteurs « pente », « sol » et « usage des terres et occupations des sols » à travers l’Analyse Hiérarchique des Procédés (AHP) de Saaty (1984). A l’analyse, la susceptibilité d’occurrence de l’aléa inondation reste importante sur près du quart du territoire. Cette importante inondabilité concerne plus du tiers (36,43 %) du bâti. Le risque élevé d’inondation reste particulièrement l’apanage des espaces fortement anthropisés qui accueillent près de trois habitants du DAA sur quatre (74,20 %). Dans une perspective de gestion anticipative des crises liées à ces évènements pluvieux extrêmes, la carte de l’inondabilité apparait comme un outil important dans la mise en place des systèmes d’alerte précoce.
Art et technique au prisme du phénomène de l’obsolescence
Authors: Guchet Xavier
Published: August 2023

Certaines œuvres d’art comportent des éléments techniques que l’industrie ne produit plus : il devient alors impossible de remplacer ces éléments lorsqu’ils ne fonctionnent plus, afin de conserver à l’œuvre son intégrité et donc sa signification. Cet épineux problème, qualifié d’obsolescence, affecte-t-il le monde de l’art de façon purement extérieure – comme si ce monde avait à subir des choix (en l’occurrence industriels) qui ne le concernent pas, qui n’ont rien à voir avec le travail et la pensée de l’artiste, qui ne mordent pas sur l’essence même de l’œuvre d’art dans le monde actuel ? L’article soutient au contraire l’idée que le phénomène de l’obsolescence met en question l’essence même du rapport entre l’art et la technique, et qu’il est la conséquence d’une pensée insuffisante de ces rapports. Problème de nature conceptuelle donc, et non de choix économiques stricto sensu.
La réélectrification du lustre monumental Parigi (1925) confrontée à la disparition des lampes à incandescence
Authors: Parmentier Mélanie
Published: August 2023

Imaginé par l’artiste Vittorio Zecchin et conçu dans l’atelier Vetri Soffiati Muranesi Cappellin Venini & C, le lustre monumental Parigi a été présenté à l’Exposition internationale des Arts décoratifs et industriels modernes de 1925, à Paris. La restauration et le remontage du lustre, à la demande du musée des Arts décoratifs de Paris qui souhaitait le présenter de nouveau en fonction, ont permis de lui rendre sa lisibilité. Son esthétique dépend étroitement de l’effet que donnait la lumière électrique dont il était doté en 1925, à savoir des lampes à incandescence. Le bannissement de ces sources lumineuses et, de manière plus générale, la question de l’obsolescence technologique, nous ont conduite à mener une étude consacrée aux différents moyens d’éclairage envisageables actuellement (lampe halogène, fluorescente compact, LED) afin de tenter de recréer l’ambiance lumineuse des années 1920.
La restauration de films : une histoire (post-)moderne
Authors: Venturini Simone
Published: August 2023

Le domaine de la préservation des films se situe aujourd’hui au cœur d’une problématique visant à comprendre et à maîtriser la transition en cours. La restauration de films ne s’est en effet rapprochée que récemment des pratiques de conservation. Dans les années 1980, on s’est ainsi efforcé d’analyser les changements intervenus au niveau du médium lui-même, mais aussi au niveau culturel et symbolique, et les années 1990 ont constitué l’apogée de la réflexion théorique et méthodologique sur la restauration cinématographique. La transition vers le numérique, en revanche, n’a pas provoqué d’évolution significative de la réflexion, mais elle a détourné l’attention vers d’autres aspects de la question. On s’est alors moins intéressé aux méthodologies de restauration qu’aux stratégies de gestion, de diffusion et de présentation. On a aujourd’hui la confirmation que le film constitue une entité ambiguë et ambivalente : d’un côté, il est un bien culturel ; de l’autre, il s’impose comme un élément central des services et des produits offerts par les archives en leur qualité d’entreprises culturelles. De la restauration au sens « noble » du terme, on a abouti, d’un côté, à une approche centrée sur les produits ou assets, et à une gestion de type économique, de l’autre côté, à une approche qui favorise la muséification et soulève des problèmes de conservation. Les relations paradoxales et dialectiques entre la conservation et l’exposition, entre un accès actif ou passif, ne s’épuisent, ne se résolvent et ne se recomposent jamais définitivement ; elles apparaissent au contraire plus que jamais comme le moteur même du système.
Fatigue Properties of Thixoformed Al-6wt%Si-2.5wt%Cu
Authors: Beil Wendel Leme , Zoqui Eugênio José
Published: August 2023

One of the main functions of semisolid metal alloy forming processes, notably rheocasting and thixoforming, is the manufacture of parts, casings and frames for mechanical assemblies and systems. These parts not only must have the required minimum mechanical properties in terms of yield strength and elongation, but also must be able to withstand cyclic tensile and compressive forces. However, there is little fatigue strength data for the materials used for these parts. The present work seeks to fill this gap by determining the fatigue limit at 107 cycles of Al-6.0wt%Si-2.5wt%Cu alloy, or simply Al6Si2.5Cu, thixoformed in a pneumatic press at 585 °C (the temperature corresponding to 40 % solid fraction) with isothermal treatment times of 30 and 60 seconds. The parts were also subjected to T6 heat treatment, for which they were solution heat treated at a temperature of 520 °C for 4 hours followed by aging at 180 °C for 10 hours. For all the conditions tested, the microstructures were characterized to determine the grain size, appearance and shape of the silicon particles, in addition to the residual porosity. For the best conditions observed, 30 s holding time and T6 heat treatment, the grain size varied between 100 µm and 130 µm; the shape factor was around 0.60, indicating an excellent degree of roundness; and there was low residual porosity of around 0.3 %, resulting in a yield strength of up to 240 MPa with 4.5 % elongation. The average fatigue strength was estimated by the staircase method and was between 95 MPa and 98 MPa for 107 cycles.
Rheological Behaviour of Secondary AlSi7Mg Alloy for Semi-Solid Processing
Authors: Tocci Marialaura , Pola Annalisa , Modigell Michael
Published: August 2023

Semisolid castings are usually produced using primary Al alloys to ensure significant mechanical performances. However, the need to increase the use of secondary alloys is becoming more and more urgent to reduce the carbon footprint of the manufacturing process. In fact, it is well known that the production of primary alloys is far more demanding in terms of energy and emissions than the recycling route. To extend the use of secondary alloys to semisolid processing, it is necessary to thoroughly understand their properties and how they can influence a material with peculiar properties as the semisolid one. Besides microstructural and mechanical features, the rheological behaviour also plays a major role when dealing with processing metals in the semisolid state. Therefore, in the present study, a rheological characterization of secondary AlSi7Mg commercial alloy was carried out and compared to that of the conventional primary alloy. In details, a different content of Fe, Cu and Mn was considered, as these impurities easily form primary intermetallic particles, which can remain dispersed in the liquid matrix of the semisolid metal. The aim of this work is to understand if this can affect the rheological properties of the considered semisolid alloy. Flow curves and yield stresses were obtained from the experimental results to compare the behaviour of the different alloys.
