When trauma turns septic: Associated factors and focus-specific mortality in 61,399 patients from the TraumaRegister DGU®

PURPOSE: Sepsis is a critical complication after severe trauma. This study aimed to identify factors associated with sepsis, to characterise sepsis foci in relation to injury pattern, and to evaluate the association of sepsis with multiple organ failure (MOF) and in-hospital mort...

Deep learning-based structural element extraction and knowledge-graph-based validation of 2D bridge drawings

The maintenance and management of existing bridge infrastructure rely on conventional two-dimensional construction drawings, which remain largely unstructured and difficult to integrate into digital workflows, including Building Information Modeling (BIM). In prestressed concrete...

The Curious Life of Walter Lode

ABSTRACT This paper is intended to serve as a supplement to the work [ PAMM ‐ Proceedings in Applied Mathematics and Mechanics 24, no. 2 (2024): e202400004] to underline the significance of the Lode angle and Lode parameter—concepts attributed to Walter Lode—for the development o...

One (Noisy) Bit to Rule Them All: Key Recovery from Randomness Leakage in ML-DSA

Abstract The Fiat-Shamir transform is one of the most widely applied methods for secure signature construction. Fiat-Shamir starts with an interactive zero-knowledge identification protocol and transforms this via a hash function into a non-interactive signature. The protocol’s z...

Measures for intersectional mental healthcare: results from a participatory interview and focus group study with psychosocial counsellors, people with experience of using mental health services and providers

BACKGROUND: Discriminatory practices and barriers to care are increasingly recognised as a significant challenge for mental healthcare institutions. Yet, little research has considered what measures people with experience of using mental health services and mental healthcare serv...

Progressive Melt Fractionation as the Primary Control on the Formation of Rare-Metal Pegmatites: Evidence for Continuous Granite–Pegmatite Evolution in the Central Kalba Ore District, Eastern Kazakhstan

Rare-metal pegmatites of the Kalba–Narym belt (Eastern Kazakhstan) represent an important source of Li, Cs, Ta, Nb, Be, and associated critical metals. Despite extensive geological investigations, the relationships between granites, pegmatites, and late-stage alteration products...

Single fuel particle emissivity evolution of biomass, coal and coal char

In solid fuel combustion systems, reacting particles form the hottest surfaces and, therefore, contribute significantly to the radiative heat balance within these environments. Recently, experimental investigations of single-particle emissivity report values for coal and various...

Direct atomistic simulation of dislocation climb in fcc Ni

Dislocation climb is one of the key processes controlling the mechanical response and microstructure evolution of materials at high temperatures. The mechanisms of this phenomenon are still unclear due to its complex nature, which involves interactions between point defects and d...

Suicide prevention through a SafetyPlan intervention for patients after a suicide attempt or in a suicidal crisis (SAFETY+): a study protocol of a randomised-controlled trial in acute inpatient psychiatric care

Individuals undergoing acute inpatient psychiatric treatment or who have recently been discharged face an especially elevated risk of suicide. Nevertheless, suicide-specific interventions are still not routinely implemented in inpatient psychiatric care in Germany. Safety plan in...

How to Benchmark Post-Quantum Accelerators

With the recent standardisation of several post-quantum cryptographic (PQC) algorithms, there is an increased focus within the hardware research community to investigate efficient accelerator designs. However, it is difficult to determine whether the reported results are directly...

Cold Atmospheric Plasma Disrupts Microbial Wound Bioburden: In Vitro, Porcine MRSA Biofilm, and Clinical Fluorescence Evidence from Bench to Bedside

Background: Biofilm-associated microbial burden is a major barrier to wound healing and is increasingly difficult to control in the era of antimicrobial resistance. This translational study evaluated the antimicrobial performance and tissue compatibility of a commercially availab...

Selenium-containing polycaprolactone 3D-printed scaffold for osteogenesis enhancement and bone healing

Bone fractures present significant surgical and healthcare challenges and require innovative bone regeneration strategies. Current research explores selenium (Se)-enhanced polycaprolactone (PCL) scaffolds for improved defect repair. Selenium, known for its antioxidant, anti-infla...

Sensory data-driven classification of complex regional pain syndrome: a multicentre cohort study

BACKGROUND: The underlying pathophysiological mechanisms of complex regional pain syndrome (CRPS) have been under debate in recent years. Previous studies identified mechanistic CRPS subtypes, which were characterised as 'cold' and 'warm' or peripheral and central phenotypes. Our...
