Bolzano et la grammaire de la représentation.
La sémantique objective présentée dans le livre II de la Wissenschaftslehre a retenu l’attention. Dans cette doctrine, le philosophe tchèque apparaît comme un précurseur de Frege. Les «représentations en soi» et «propositions en soi» bolzaniennes appartiennent à un domaine qui ressemble au «sens» frégéen. Il faut pourtant relever que Bolzano parle bien de «représentations en soi», et ne fait pas, contrairement à Frege, une différence entre la sphère du sens et celle de la représentation. Certes la représentation en soi est indépendante de la représentation subjective, mais une forme de corrélation subsiste entre elles. En fait, la doctrine de la représentation objective fonde une doctrine de la représentation subjective, présentée dans la «Théorie de la Connaissance» de la Wissenschaftslehre. Sur la base de sa sémantique, Bolzano développe une philosophie de l’esprit dans laquelle le concept de représentation joue un rôle central. Le présent article étudie cette philosophie de l’esprit.

Interview with Karl Duffek and Gerhard Marchl, Karl-Renner-Institut.
The history and the activities of the Karl-Renner-Institut, which is the political academy of the Social Democratic Party of Austria (SPÖ), are in the centre of this interview with director Karl Duffek and his colleague Gerhard Marchl. The institute's foundation in the early 1970s was an initiative of former Austrian Chancellor Bruno Kreisky. The Karl-Renner-Institut is essentially a forum of discussion and education as well as a think tank. Its activities focus on political education for a broader public, trainings for members on all levels of the party, programmatic work, and co-operation with international partners. Other key aspects, which are addressed in the interview, are the differences and similarities to the Friedrich Ebert Foundation, to what extent history/historiography is of significance in the work of the institute, as well as its recent publications in the field of history.

Abstract
Galactic cosmic-ray (GCR) particles have a significant impact on the particle-induced background of X-ray observatories, and their flux exhibits substantial temporal variability, potentially influencing background levels. In this study, we present 1 day binned high-energy reject rates derived from the Chandra-ACIS and XMM-Newton EPIC-pn instruments, serving as proxies for the GCR particle flux. We systematically analyze the ACIS and EPIC-pn reject rates and compare them with the AMS proton flux. Our analysis initially reveals robust correlations between the AMS proton flux and the ACIS/EPIC-pn reject rates when binned over 27 day intervals. However, a closer examination reveals substantial fluctuations within each 27 day bin, indicating shorter-term variability. Upon daily binning, we observe finer temporal structures in the data sets, demonstrating the presence of recurrent variations with periods of ∼25 days and 23 days in the ACIS and EPIC-pn reject rates, respectively, spanning the years 2014–2018. Notably, during the 2016–2017 period, we additionally detect periodicities of ∼13.5 days and 9 days in the ACIS and EPIC-pn reject rates, respectively. Intriguingly, we observe a time lag of ∼6 days between the AMS proton flux and the ACIS/EPIC-pn reject rates during the second half of 2016. This time lag is not visible before 2016 and after 2017. The underlying physical mechanisms responsible for this time lag remain a subject of ongoing investigation.
Multiwavelength Emission of the Gamma-Ray Burst Prompt Phase. I. Time-resolved and Time-integrated Polarizations
Authors: Li Jia-Sheng , Lan Mi-Xiang , Wang Hao-Bing 
Published: July 2024

Abstract
The time-integrated polarization degree (PD) in the prompt optical band of a gamma-ray burst (GRB) was predicted to be less than 20%, while the time-resolved one can reach as high as 75% in the photosphere model. Polarizations in the optical band during the GRB prompt phase have not previously been studied in the framework of the magnetic reconnection model. Here, a three-segment power law of the energy spectrum is used to reconstruct the Stokes parameters of the magnetic reconnection model. Multiwavelength light curves and polarization curves from the optical band to MeV gamma rays in the GRB prompt phase are studied. We found that, depending mainly on the jet dynamics, there is a long-lasting high-PD phase in all calculated energy bands for the typical parameter sets. The time-resolved PD could be as high as 50%, while the time-integrated one is roughly 17% in the optical band. The time-resolved PD in X-rays can reach 60% and the time-integrated one is around 30%–40%. The evolution of polarization angle (PA) is random in both optical and gamma-ray bands for the photosphere model, while it is roughly constant in the synchrotron models. Therefore, future time-resolved PA observations in the prompt optical or gamma-ray band could distinguish between the photosphere and synchrotron models.
On the Interacting/Active Lifetime of Supernova Fallback Disks around Isolated Neutron Stars

Published: July 2024

Abstract
The fallback disk model is widely accepted to explain long-period neutron stars (NSs) that cannot be simulated by magnetic dipole radiation. However, there was no confirmed detection of disks from the newly discovered long-period pulsars GLEAM-X 162759.5-523504.3 and GPM J1839-10 and the slowest known isolated NS 1E 161348-5055. This might be because the disks have either been in a noninteracting/inactive state where their emission is too weak to be detected or have been disrupted. In this work, we conduct simulations to examine the lifetime of supernova fallback disks around isolated NSs. We assume that the disks' mass varies in a self-similar way, and their interaction with the NS occurs only in an interacting/active state. Our results reveal that nearly all the interacting lifetimes for the disks are shorter than 105 yr, while the existence lifetimes are considerably longer.

Abstract
Understanding the nature of the luminous 1991T-like supernovae (SNe) is of great importance to SN cosmology as they are likely to have been more common in the early Universe. In this paper, we explore the observational properties of 1991T-like SNe to study their relationship to other luminous, slow-declining Type Ia supernovae (SNe Ia). From the spectroscopic and photometric criteria defined in Phillips et al., we identify 17 1991T-like SNe from the literature. Combining these objects with 10 1991T-like SNe from the Carnegie Supernova Project-II, the spectra, light curves, and colors of these events, along with their host galaxy properties, are examined in detail. We conclude that 1991T-like SNe are closely related in essentially all of their UV, optical, and near-infrared properties—as well as their host galaxy parameters—to the slow-declining subset of Branch core-normal SNe and to the intermediate 1999aa-like events, forming a continuum of luminous SNe Ia. The overriding difference between these three subgroups appears to be the extent to which 56Ni mixes into the ejecta, producing the premaximum spectra dominated by Fe iii absorption, the broader UV light curves, and the higher luminosities that characterize the 1991T-like events. Nevertheless, the association of 1991T-like SNe with the rare Type Ia circumstellar material SNe would seem to run counter to this hypothesis, in which case 1991T-like events may form a separate subclass of SNe Ia, possibly arising from single-degenerate progenitor systems.
Royaume-Uni. Le droit du travail, un enjeu essentiel des prochaines élections législatives
Authors: Freyssinet Jacques 
Published: July 2024

Les élections législatives du 4 juillet 2024 au Royaume-Uni devraient mettre fin à quatorze années de gouvernements conservateurs et permettre des inflexions dans la politique économique et sociale. L’un des domaines importants des changements potentiels concerne le droit du travail. Le programme du parti travailliste contient un nombre élevé d’engagements. Nous en retenons quatre qui constituent des enjeux cruciaux dans le contexte actuel : les contrats zéro heure, les procédures de licenciement et réembauche, la survie des droits hérités des directives communautaires, les entraves à l’exercice du droit de grève.
Le rire sur la palette

Published: July 2024

Le motif du rire, qui apparaît dans les représentations du Christ à la Renaissance, ne disparaît pas de la peinture religieuse à l’époque de la Contre-Réforme, contrairement à ce que l’on croit parfois : sa présence indirecte ou discrète suggère même l’allégresse spirituelle ou la réalité de l’Incarnation.
Protection du marché du travail dans l’espace et dans le temps
Authors: Ferragina Emanuele , Danilo Filetti Federico 
Published: July 2024

Cette étude 2 mesure et interprète l’évolution de la protection du marché du travail dans 21 pays à revenu élevé sur trois décennies, en utilisant les concepts de « diversité institutionnelle » et de « trajectoire de changement » déjà développés dans la littérature, notamment par G. Esping-Andersen. Le niveau de protection du marché du travail est évalué en tenant compte de quatre dimensions institutionnelles (protection de l’emploi, protection contre le chômage, maintien du revenu, politique active de l’emploi) et du changement de la composition de la force de travail. Il tient compte de l’évolution conjointe des institutions du marché du travail, de leurs complémentarités et de leurs relations avec le système social. La nature multidimensionnelle de la protection du marché du travail est traitée à l’aide d’une analyse en composantes principales et les caractéristiques des trajectoires de changement des pays avec un score composite. La contribution à la littérature scientifique est triple. Premièrement, une typologie révisée tient compte des processus de changement entre 1990 et 2015 et regroupe les pays sur la base des niveaux de coordination et de solidarité. Deuxièmement, nous constatons que malgré un écart persistant, une grande majorité des économies coordonnées, qui ont connu une baisse du niveau de protection du marché du travail, se sont rapprochées des économies libérales. Enfin, une taxonomie à cinq catégories des trajectoires de changement (libéralisation, dualisation, flexicurité, dé-dualisation, protection renforcée) montre que ces trajectoires ne sont pas toujours dépendantes ni cohérentes avec les variétés institutionnelles précédemment développées dans la littérature scientifique.
Pour une histoire des pétrarquismes ibériques, de Sá de Miranda aux poètes des Flores de poetas ilustresde España (1526-1605)
Authors: Behar Roland 
Published: July 2024

Dans la péninsule Ibérique comme dans le reste de l’Europe, le pétrarquisme est sans doute le mouvement poétique majeur du xvie siècle, tant en portugais qu’en castillan. L’histoire conjointe des pétrarquismes des deux couronnes et des deux langues, depuis leurs origines communes – quand Francisco Sá de Miranda, Juan Boscán et Garcilaso de la Vega rapportent le pétrarquisme d’Italie dans les années 1520 – jusqu’au moment où, à l’aube du xviie siècle, le pétrarquisme cesse d’être le modèle de référence de l’invention poétique, est celle d’une mode – liée à celle, plus générale, de l’italianisme codifié dans le Courtisan de Castiglione. Ils suscitèrent des oppositions, vives parfois, qui contribuèrent à définir comme telle cette mode, firent l’objet de théorisations et de compilations dans des cartapacios, adoptèrent des formes éditoriales précises – les recueils de Rimas, individuels (sur le mode des Rerum vulgarium fragmenta de Pétrarque) ou collectifs, manuscrits ou imprimés – et enfin se traduisirent par la diffusion d’une koiné littéraire commune à tous les poètes de la fin du xvie et du début du xviie siècle, passés maître dans l’art d’imiter Pétrarque et inventeurs, pour les plus géniaux, de nouveaux langages poétiques.
High-risk HPV Prevalence Estimates among Older Patients: Implications for Cervical Cancer Screening Programs
Authors: Mittal Sneha , Kansal Yamini , Singh Bhumika , Gupta Vineeta 
Published: July 2024

Background:
Due to the heterogeneity of existing studies and wide range of human papilloma virus (HPV) prevalence in India, further research into the incidence of HR-HPV and its spectrum of genotypes is essential to develop screening policies. This study aimed to determine the incidence and demographic distribution of HR-HPV among cisgender female patients attending a tertiary care facility in North India.

Materials and Methods:
This study was conducted in the Department of Obstetrics and Gynaecology, SGRR Institute of Medical and Health Sciences, Dehradun, India. HPV-DNA test results of 653 female patients were assessed for HR-HPV positivity, genotyping, and age-based differences via Chi-square analysis.

Results:
Overall prevalence of HR-HPV was 4.90%, HPV-16 was 1.37%, HPV-18 was 0.76%, and HPV non-16,18 was 2.7%. In patients ≤ 50 years, prevalence of HPV-16 was 0.97%, HPV-18 was 0.38%, and HR-HPV non-16,18 was 2.71%. In patients > 50 years, prevalence of HPV-16 was 2.89%, HPV-18 was 2.17%, and HR-HPV non-16,18 was 2.89%. The difference in the prevalence of HPV-16,18 between patients ≤ and > 50 years was found to be highly statistically significant (P = 0.007485). The difference in the prevalence of total HR-HPV between patients ≤ and > 50 years was not found to be statistically significant (P = 0.059905).

Conclusion:
Our study’s finding of higher HR-HPV positivity rates in patients > 50 years emphasizes the need for continued HR-HPV-DNA-based screening of this cohort. With widespread use in post-menopausal patients, HPV screening can serve as an important armamentarium in the fight against cervical cancer.

Authors: El-Tatawy Rania Ahmed , Gheida Shereen , Soliman Ghada Adbel Moamen , Ismail Mayada 
Published: July 2024

ABSTRACT

Background:
Telogen effluvium (TE) is the most common hair loss. Vitamin D is related to hair and skin diseases due to its immunomodulatory and anti-inflammatory effects.

Objective:
To investigate Vitamin D serum level role in TE pathogenesis.

Patients and Methods:
Forty females with TE were collected and twenty age- and sex-matched healthy individuals as controls. Serum 25(OH) Vitamin D level was estimated prior and 3 months after oral Vitamin D.

Results:
The mean serum 25(OH) Vitamin D levels were significantly lower in TE patients than controls (13.31 ± 5.8 ng/ml vs. 33.61 ± 8.16 ng/ml) respectively, P < 0.001. The mean serum 25(OH) Vitamin D levels before treatment in acute TE was 12.31 ± 6.88 ng/ml, compared to 10.6 ± 3.9 ng/ml in chronic TE without a significant difference, (P = 0.544). The mean serum 25(OH) Vitamin D levels in TE group after 3 months oral Vitamin D therapy were 38.4 ± 15.22 ng/ml with significant increase compared to pretreatment level, (P < 0.001). However, without a significant difference between acute TE (45.4 ± 9.22 ng/ml) and chronic TE (42.1 ± 10.6 ng/ml), (P = 0.711).

Conclusion:
Oral Vitamin D has a promising effect in TE treatment, but the results need to be verified on a larger scale with evidence-based recommendation regarding the exact dose and treatment duration.

Published: July 2024

Abstract

Background:
Radiotherapy is one of the routine treatment strategies for breast cancer (BC) patients. Different responses of the patient to radiation due to different intrinsic radiosensitivity (RS) were induced to the researcher try to introduce a standard assay for the prediction of RS. Clonogenic assay is recognized as a gold standard method in this subject but because of some of its disadvantages, it is needed for alternative assays. In this study, two assays were evaluated for this reason in ten BC patients with different RSs.

Methods:
The peripheral blood of 10 volunteers with BC was obtained, and the peripheral blood mononuclear cells were extracted. After exposed with 2 Gy, survival fraction at 2 Gy (SF2) was calculated by clonogenic assay. γ-H2AX assay was performed for all patients, and apoptosis assay was evaluated for three represented categorized patients.

Results:
RS of patients showed SF2 and categorized in three groups (high, medium, and low RS). Double-strand breaks (DSBs) were decreased in high radiosensitive patients, but the residual DSBs were clearly higher than other two groups. It is shown that the repair system in these patients is lower active than others. Apoptosis frequency in patient 4 is highly active which could induce the enhancement of her RS.

Conclusion:
γ-H2AX and apoptosis assays could predict the intrinsic RS, but evaluation of them separately is not sufficient for this aim. It is necessary to consider all the parameters together and consideration of the combination of assays could fit a better prediction of intrinsic RS.

Abstract

Objectives:
The aim of the present study was to examine the immunoexpression of CD44, p16 and VEGF in oral squamous cell carcinoma (OSCC) and correlate them to clinicopathological parameters and survival outcomes in order to clarify their prognostic impact.

Material and Methods:
A total of 68 individuals with OSCC recruited between 2011 and 2015 from two referral centres were enrolled in the study. The samples were placed on silanized glass slides and subjected to immunohistochemistry using anti-p16, anti-CD44 and anti-VEGF antibodies. The H Score was used for p16 and VEGF, while CD44 was scored according to the percentage of stained cells. Chi-square tests and Fisher’s exact probability tests were used to compare clinicopathological characteristics according to the immunohistochemical expression, while overall survival and disease-free survival were estimated and compared using the Kaplan-Meier method and log-rank test, respectively. For all hypothesis tests, the level of significance was set at P ≤ 0.05.

Results:
No correlation was observed between the expression of tumour VEGF, p16 and CD44, and the clinicopathological characteristics analysed. Patients with high stromal VEGF expression had better disease-free survival than patients with low VEGF expression (P = 0.023).

Conclusion:
In summary, P16, CD44 and tumour VEGF did not prove to be good prognostic biomarkers. Stromal VEGF expression is suggested to be a good candidate prognostic biomarker, although additional studies are needed.
