Analytical dual flip angle R1 calculation outside the small-angle regime

Purpose: To evaluate a new analytical estimator for R1 and apparent proton density (𝐴) from short-TR dual flip angle data which does not rely on the small flip angle approximation and can thus be applied to a broader range of data, especially where relatively large flip angles are needed to achieve sufficient T1-weighting for R1 estimation.Theory and Methods: A rational approximation of the Ernst

Understanding Tourist’s Behavioral Intentions in Selecting Local Home-Based Accommodation in Iran

The purpose of this study is to investigate tourists’ behavioral intentions when selecting LHA for stays, considering the effects of the Attitude-Social Influence‑Efficacy Model, social identity theory, and accommodation attributes to predict guest behavior Applying a quantitative research design, questionnaire survey, and structural equation modeling for analyzing the data, the results revealed t

The 1951 refugee convention from a welfare-state perspective

This paper studies how national welfare-state institutions influenced the positions states took on the social rights of refugees during the negotiation, adoption, and ratification of the 1951 United Nations Convention Relating to the Status of Refugees. Through an analysis of the drafting process and the reservations and interpretative declarations states issued when rat-ifying the Convention, the

Safety and equity in scaling minimally invasive surgery worldwide in 109 countries using cholecystectomy as a tracer procedure : a prospective cohort study

BACKGROUND: Minimally invasive surgery is rapidly expanding globally, yet there is insufficient knowledge of how to scale this technology safely and equitably across diverse health systems. We aimed to identify health-system factors associated with safe implementation of minimally invasive surgery globally, using minimally invasive cholecystectomy as a tracer procedure.METHODS: We conducted a mult

The Solo Tuba: Re-evaluating instruments, timbres and performance practices

This article explores how quantitative organological analysis can be implemented alongside historical musicology to help stimulate creativity in performance practice while promoting a diversity of timbre that is often lost amidst the hegemonic propagation of homogenized, normalized modern musical instruments. The tuba family provides an insightful case study demonstrating how the history and devel

Genomic evidence of varicella-zoster virus among Mpox-suspected cases in Ethiopia during the 2022 Mpox multi-country outbreak

Chickenpox is a highly contagious viral infection caused by varicella-zoster virus (VZV) whose clinical manifestations mimic mpox posing challenges for diagnosis without laboratory confirmation. Here, we investigated VZV among the mpox-suspected cases, May to October 2022, in Ethiopia. Samples were collected from 202 mpox-suspected cases in 11 of Ethiopia’s 14 regions and screened for mpox virus b

A Plaintext-checking Oracle for Decapsulation Leakage in the NIST HQC FPGA Reference Implementation

In this thesis, we evaluate the side-channel security of the NIST HQC post-quantum cryptosystem by analysing the official FPGA decapsulation implementation. A hardware wrapper was created to interact with the HQC decapsulation modules, enabling ciphertext decapsulation with precise power trace capturing using a ChipWhisperer CW305 and Husky setup. A dataset with 20k power traces was generated from

Robert Musil – novelist, psychologist, sociologist : Contributions to classical sociology and the analysis of modernity

The writings of the Austrian novelist and essayist Robert Musil provide sociology with vital problems and reflections. Indeed, Musil, not least in the novel The Man without qualities, introduces discussions that extend conventional and recurrent understanding of modernity – sociology’s general object of analysis. The paper focuses on three major sets of questions in Musil’s work: 1) the shapelessnThe writings of the Austrian novelist and essayist Robert Musil provide sociologywith vital problems and reflections.

Void, crisis, abundance : Images of Classical Modernity

This presentation offers an outline of classical modern reflection (sociology, cultural theory, literature) on the constitution and transformation of modernity, its cultural and mental dispositions. The discussion focuses on key themes and experiences of classical modernity: void, crisis and abundance. It is argued that classical modernity may be conceived as a conceptual archive of influential id

Objectively Quantifying the Shrinking Worlds of People With Chronic Dyspnea : A National, Online Survey

Context: Chronic dyspnea is subjective but with objective (measurable) consequences. It is often poorly assessed because people have modified their lifestyles to avoid exertion that generates dyspnea. Objectives: This study sought any relationship between respondents’ self-reported long-term breathlessness limiting exertion (hereafter chronic dyspnea) and distance travelled from the room in which

Climate change threats and affective polarization. Exploring the role of negative emotional reactions

Climate change mitigation requires collective efforts, but the fact that the climate issue has become highly polarized may thwart such endeavors. In this article, we examine how negative emotions in response to climate change threats are associated with affective polarization—the tendency to view those from opposing political groups with hostility and bias, and to view those from one's own group m

Magnetization transfer imaging using non-balanced SSFP at ultra-low field

Purpose: Ultra-low field MRI scanners have the potential to improve health care delivery, both through improved access in areas where there are few MRI scanners and allowing more frequent monitoring of disease progression and treatment response. This may be particularly true in white matter disorders, including leukodystrophies and multiple sclerosis, in which frequent myelin-sensitive imaging, su

Squaramide-based supramolecular gels for the removal of organic dyes from water matrices

A novel family of symmetric squaramide-based LMWGs has been synthesised, functionalized with both dansyl moieties and alkyl chain spacers of different lengths (n = 3 and n = 4 named L1 and L2, respectively). L1 and L2 are able to form hydrogels in the DMSO : H2O mixture in different ratios and concentrations. The gels obtained were characterized by means of rheology, TEM and small angle X-ray scat
