Background and purpose — The nonagenarian (those aged 90 years and older) population is expected to double in the next 20 years. This demographic age quake may have a significant impact on the incidence of total knee arthroplasty (TKA), although current literature provides limited data. We examined death and revision rates, patient-reported outcomes (PROs) and bias on patient selection of nonagena

In the ActivAbles and STARR projects we are developing interactive training tools for stroke survivors. As our initial user studies pointed to balance being a key ability, one of the developed tools is an interactive balance mat. While balance equipment is common, interactive balancing equipment for persons with poor balance is less common. Equipment exists for persons with good balance (eg. Wii),

Algorithms for secure encryption in a post-quantum world are currently receiving a lot of attention in the research community. One of the most promising such algorithms is the code-based scheme called QC-MDPC, which has excellent performance and a small public key size. In this work we present a very efficient key recovery attack on the QC-MDPC scheme using the fact that decryption uses an iterati

Technical biases are introduced in omics data sets during data generation and interfere with the ability to study biological mechanisms. Several normalization approaches have been proposed to minimize the effects of such biases, but fluctuations in the electrospray current during liquid chromatography-mass spectrometry gradients cause local and sample-specific bias not considered by most approache

A focus on misrecognition allows us to move between levels of analysis in a holistic fashion. If misrecognition works through the conscious and the unconscious we can account for the many overlapping insecurities and securities believed to exist at the individual, group, or state level – and thus felt. These insecurities also present themselves through the categories used to describe them and the

In this paper we present a multidisciplinary, developmental analysis of a Dominican Republic Vodou servidor (“Marcos”), from childhood to early adulthood, integrating ethnographic observation, field documentation, and anthropological analysis, with relevant constructs from developmental, personality, and clinical psychology. Marcos transitioned from a child with many problems to a young adult who

Innovation in retailing is under-investigated in academia and yet highly relevant in practice given the current changes in the retail landscape. Although retailing is often characterised by a dynamic and highly competitive environment, retail organizations are not often considered as “innovative,” at least when compared with manufacturing industries or when using existing innovation frameworks in
