Astronáutica Kepleriana

open access: yesCaderno Brasileiro de Ensino de Física, 1996
En el presente trabajo se propone el cálculo de la órbita de un satélite artificial utilizando solo las Leyes de Kepler. Se respeta el bagaje de conceptos disponibles en la época de Kepler y se aprovecha este enfoque del problema de dos cuerpos en ...

Investigating the Atmospheric Mass Loss of the Kepler-105 Planets Straddling the Radius Gap

open access: yesThe Astronomical Journal
An intriguing pattern among exoplanets is the lack of detected planets between approximately 1.5 R _⊕ and 2.0 R _⊕ . One proposed explanation for this “radius gap” is the photoevaporation of planetary atmospheres, a theory that can be tested by studying ...

Multinational transfusion practices and outcomes in haematology patients admitted to the intensive care unit

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives The number of critically ill patients with haematological conditions is increasing, yet transfusion practices in this population remain poorly defined. This study aimed to compare transfusion strategies in critically ill patients with versus without haematological conditions.

Different Device Architectures for Bulk-Heterojunction Solar Cells

open access: yesFrontiers in Materials, 2016
We report different solar cell designs which allow a simple electrical connection of subsequent devices deposited on the same substrate. By arranging so-called standard and inverted solar-cell architectures next to each other, a serial connection of the ...

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Enfortumab vedotin plus pembrolizumab in treatment‐naïve metastatic urothelial carcinoma patients: An Austrian real‐world analysis

open access: yesInternational Journal of Cancer, Volume 158, Issue 6, Page 1654-1665, 15 March 2026.
What's new? New antibody‐drug conjugates (ADCs) and immunotherapies have helped expand treatment options for urothelial carcinoma (UC). Clinical trials suggest that the ADC enfortumab vedotin (EV) and the immunotherapeutic agent pembrolizumab, when used in combination, are especially effective against UC.

Digital Adaptive Learning in Secondary Mathematics: A Qualitative Interview Study With Austrian Teachers on Perceptions, Needs, and Implementations

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background One of the advances in learning with technology is digital adaptive learning (AL) materials for mathematics. Although empirical studies have shown the benefits of AL for learners and teachers, little research has been done on teachers' perceptions and needs of digital AL and their plans for implementation in mathematics classrooms ...

Estudo da atividade estelar da Kepler-289 a partir da modelagem de trânsitos planetários

open access: yesRevista Brasileira de Ensino de Física
Resumo Neste trabalho apresentamos um estudo sobre atividade estelar e trânsitos planetários de exoplanetas. Sem apresentar rigor matemático demostramos como obter parâmetros físicos como: temperatura, intensidade e posição de manchas em superfície de ...
