In situ electron microscopy of LaNiO3 transformation during reduction and methane dry reforming

Abstract By in situ electron microscopy we show the intermediate phase formation during decomposition of LaNiO 3 , a model methane dry reforming (DRM) catalyst, under different gas atmospheres. By combining dark- and bright-field imaging with secondary-electron contrast and opera...

A Multilaboratory Evaluation of Backwater Effects at Bridges Resulting from Diverse Floating Debris Compositions during the 2021 Flood Event in Europe

Abstract The flood event of July 2021 in Western Europe was characterized by water levels far above the 100-year design flood and by billions of euros in damages. During the flood, voluminous debris accumulations of up to <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" a...

Transient acute kidney injury following femoral fracture in mice

Aims Femoral shaft fractures are commonly associated with high-energy trauma, and affect individuals of all ages. Kidney dysfunction frequently complicates fracture healing, and trauma-related acute kidney injury (TRAKI) elevates the risk of adverse outcomes. The mechanisms of po...

DECIDER-2: Prospective randomized multicenter phase III trial of decitabine and venetoclax administered in combination with all-trans retinoic acid or placebo in patients with acute myeloid leukemia who are ineligible for induction chemotherapy

Abstract Background Acute myeloid leukemia (AML) is predominantly a disease of older patients with a poor long-term survival. Approval of the combination of venetoclax (VEN) with azacitidine (AZA) or decitabine (DAC) in the European Union in 2021 for the treatment of patients wit...

Snapquery: FAIR Management of Query Sets to Mitigate Query Rot in Knowledge Graphs

Will the “cats” Wikidata SPARQL query example still work in the future? While link rot has been a known issue, the Query Rot problem has not been investigated much in the past. We introduce an approach for quality assessment and refactoring of query sets and evalu- ate its implem...

A Case Report on Cerebral Autoregulation in Posterior Reversible Encephalopathy Syndrome After Aneurysmal Subarachnoid Hemorrhage

BACKGROUND: Disturbed cerebral autoregulation remains a theoretical contributor to posterior reversible encephalopathy syndrome (PRES), but it has not been captured before. We report invasively measured autoregulation indices in a 50-year-old female with aneurysmal subarachnoid h...

How Identity-Specific Workplace Support and Authenticity Drive Individual Entrepreneurial Orientation: Evidence From Sexual and Gender Minoritized Employees

Research on individual entrepreneurial orientation (Ind.EO) has yet to reveal the psychological conditions under which employees demonstrate Ind.EO in the workplace. Addressing this gap, we theorize that authenticity is a crucial mechanism linking identity-specific support to Ind...

Blood-based versus crystalloid cardiopulmonary bypass priming in left ventricular assist device surgery: impact on end-organ function and survival

OBJECTIVES: Cardiopulmonary bypass (CPB) priming may influence hemodilution, bleeding and end-organ injury during HeartMate 3 (HM3) implantation, but evidence in contemporary left ventricular assist device (LVAD) surgery is limited. METHODS: We retrospectively analysed 92 HM3 imp...

Feasibility of a German High-Frequency Neonatal and Pediatric Intensive Care Dataset (AIx-Neo-Guard Dataset): Secondary Data Cohort Study

BACKGROUND: Available information about existing neonatal and pediatric intensive care datasets is scarce. OBJECTIVE: The objective was to evaluate the feasibility of a monocentric high-frequency dataset of neonatal and pediatric intensive care patients in a cohort study. METHODS...
