Mechanism of Hot-Carrier Photoluminescence in Sn-Based Perovskites.

Adv Mater

December 2024

Zernike Institute for Advanced Materials, University of Groningen, Nijenborgh 4, 9747 AG, Groningen, The Netherlands.

Metal halide perovskites have shown exceptionally slow hot-carrier cooling, which has been attributed to various physical mechanisms without reaching a consensus. Here, experiment and theory are combined to unveil the carrier cooling process in formamidinium (FA) and caesium (Cs) tin triiodide thin films. Through impulsive vibrational spectroscopy and molecular dynamics, much shorter phonon dephasing times of the hybrid perovskite, which accounts for the larger blueshift in the photoluminescence seen at high excitation density for FASnI compared to CsSnI is reported.

Superconductivity in infinite layer nickelates Nd_{1-x}Sr_{x}NiO_{2} has so far been achieved only in thin films, raising questions on the role of substrates and interfaces. Given the challenges associated with their synthesis it is imperative to identify their intrinsic properties. We use resonant inelastic x-ray scattering to investigate the influence of the SrTiO_{3} capping layer on the excitations of Nd_{1-x}Sr_{x}NiO_{2} (x=0 and 0.

Background: Many studies have analysed the bibliometric characteristics of highly cited articles in dentistry, and orthodontics. However, scant attention has been paid to articles with low citation rates. The aim of this study is to identify author- and article-specific factors that may be associated with a low citation rate at least 6 years after publication.

Understanding the intricate interactions of molecular dyes with nucleic acids is pivotal for advancing medical and biochemical applications. In this work, we present a comprehensive study of the interplay between a novel series of bis-acridine orange (BAO) dyes and double-stranded DNA (dsDNA). These BAO dyes were intentionally designed as two acridine orange units connected by neutral linkers featuring a 2,5-disubstituted thiophene moiety.

Management of immune-mediated glomerular diseases in the elderly.

Ren Fail

December 2024

S.C.D.U. Nefrologia, Dialisi e Trapianto, ARNAS Brotzu, Cagliari, Italy.

Article Synopsis
  • Managing immune-mediated kidney diseases in elderly patients (≥75 years) is challenging due to age-related health issues and comorbidities.
  • Current classification systems and treatment guidelines are insufficient for this age group, necessitating a more tailored approach.
  • Treatment often involves immunosuppressive therapies, but careful drug choice and dosage are essential to minimize side effects, requiring a collaborative and patient-centered management strategy.

Right-left sEMG burst synchronization of the lumbar erector spinae muscles of seated violin players.

Sci Rep

October 2024

Dept. of Electronics and Telecommunications, LISiN, Politecnico di Torino, Turin, Italy.

Burst-like activation of postural muscles has been previously described and plays a crucial role in elucidating the strategies for postural control adopted by the central nervous system (CNS). A spatio-temporal descriptor of surface electromyographic (sEMG) bursts (STB) is proposed and applied to statistically quantify the burst-like activity of the right and left (R-L) lumbar erector spinae muscle of nine seated violinists playing for two hours. The STB signal is the number of pixels of the high density sEMG (HDsEMG) maps simultaneously showing sEMG amplitude above a given threshold.

Article Synopsis
  • Elites were very important in shaping Europe after the Roman Empire fell, influencing both big and small communities during the Early Middle Ages.
  • Researchers studied a community in Italy from the 6th to 8th centuries and found that it was made up of related elite families that grew into one big family over time.
  • This community was diverse, welcoming different people as it developed, showing that powerful leaders could bring together various backgrounds instead of just sticking to their own.

Epilepsy after acute central nervous system complications of pediatric hematopoietic cell transplantation: A retrospective, multicenter study.

Seizure

October 2024

IRCCS Istituto delle Scienze Neurologiche di Bologna, U.O.C. Neuropsichiatria dell'età pediatrica, Member of the ERN EpiCare, Bologna, , Italy; Department of Medical and Surgical Sciences (DIMEC), Alma Mater Studiorum - University of Bologna, Bologna, Italy. Electronic address:

Article Synopsis
  • The study investigates long-term epilepsy outcomes in pediatric patients who experienced acute central nervous system complications during hematopoietic cell transplantation (HCT).
  • Data was collected from 94 patients, revealing that common acute complications included posterior reversible encephalopathy syndrome and infections, with a notable incidence of acute symptomatic seizures.
  • Findings indicate that 9.6% of patients were diagnosed with long-term epilepsy, especially those who experienced acute symptomatic status epilepticus, highlighting the need for specialized neurological follow-up in these cases.

A taxonomy of cyber risk taxonomies.

Risk Anal

August 2024

Operational Risk and Reinsurance Solutions, Howden Group Holdings, London, UK.

The field of cyber risks is rapidly expanding, yet significant research remains to be conducted. Numerous taxonomy-based systems have been proposed in both the academic literature and industrial practice to classify cyber risk threats. However, the fragmentation of various approaches has resulted in a plethora of taxonomies, often incongruent with one another.

Background: It is difficult to quantify the impact of the COVID-19 pandemic on mental health as many community surveys have limited quality, rely on screening tests to measure mental health conditions and distress, and often use convenience samples. Moreover, robust surveys come mainly from high-income countries.

Aim: To measure the prevalence of depressive disorders with onset during the pandemic in a community of a Lower-Middle-income country (LMIC)-Tunisia.

A new series of muscarinic acetylcholine receptor (mAChR) ligands obtained by inserting different substituents in position 2 of the potent 6,6-diphenyl-1,4-dioxane antagonists 4 and 5 was designed and synthesized to investigate the influence of steric bulk on the mAChR affinity. Specifically, the insertion of a 2-methyl group, affording compounds 6 and 9, resulted as the most favorable modification in terms of affinity for all muscarinic subtypes. As supported by computational studies performed on the hM receptor, this substituent may contribute to stabilize the ligand within the binding site by favoring the formation of stable interactions between the cationic head of the ligand and the residue D105.

Thymosin β and β Expression in Human Organs during Development: A Review.

Cells

June 2024

Laboratorio di Proteomica, Centro Europeo di Ricerca sul Cervello, Fondazione Santa Lucia IRCCS, 00179 Roma, Italy.

This review summarizes the results of a series of studies performed by our group with the aim to define the expression levels of thymosin β and thymosin β over time, starting from fetal development to different ages after birth, in different human organs and tissues. The first section describes the proteomics investigations performed on whole saliva from preterm newborns and gingival crevicular fluid, which revealed to us the importance of these acidic peptides and their multiple functions. These findings inspired us to start an in-depth investigation mainly based on immunochemistry to establish the distribution of thymosin β and thymosin β in different organs from adults and fetuses at different ages (after autopsy), and therefore to obtain suggestions on the functions of β-thymosins in health and disease.

Article Synopsis
  • A study analyzed 663 patients with transfusion-dependent β-thalassemia who received one of three iron chelation therapies (deferoxamine, deferiprone, or deferasirox) for up to 10 years, showing significant reductions in serum ferritin levels across all treatments.
  • Despite these reductions, there were no notable changes in liver iron concentration or heart health indicators, as patients started with low levels of iron in these areas.
  • While deferasirox was linked to better morbidity and mortality-free survival compared to deferoxamine, overall, the iron chelation effectiveness was similar among all three treatments in managing mild-to-moderate iron overload in patients.
