- Objectives:& nbsp;Mindfulness-based interventions have recently been shown to be a promising option for treating posttraumatic stress. The current study aimed to investigate the effects of an online mindfulness-based intervention on ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) symptoms at a 3-month follow-up.& nbsp;Methods:& nbsp;An RCT design with three measurement points (pre-intervention, post-intervention, and 3-month follow-up) was used to investigate the effects of an 8-week online mindfulness intervention. In total, 53 traumatized young adults (M-age = 23.21, SDage = 2.81; 84.9% female) participated in the study: 17 in the intervention group and 36 in the waiting list control group.& nbsp;Results:& nbsp;Intervention group and waiting list control group comparison revealed that the intervention was effective for reducing CPTSD disturbances in self-organization symptoms (d = -0.84 [-1.44; -0.24]), specifically, negative self-concept (d = -0.66 [-1.25; -0.07]) and disturbances in relationships (d = -0.87 [-1.47; -0.27]), at 3-month follow-up. There were no between-group effects for PTSD symptoms from pre-test to follow-up.& nbsp;Conclusion:& nbsp;This is one of the first RCT studies to report follow-up effects of an online mindfulness-based intervention for ICD-11 PTSD or CPTSD symptoms. Our study yielded that the effects of mindfulness-based internet intervention on CPTSD symptoms tend to retain over time.

- Background: The COVID-19 pandemic demanded exceptional physical and mental effort from healthcare workers worldwide. Since healthcare workers often refrain from seeking professional psychological support, internet-delivered interventions could serve as a viable alternative option.Objective: We aimed to investigate the effects of a therapist-guided six-week CBT-based internet-delivered stress recovery intervention among medical nurses using a randomized controlled trial design. We also aimed to assess program usability.Methods: 168 nurses working in a healthcare setting (Mage = 42.12, SDage = 11.38; 97 % female) were included in the study. The intervention group included 77 participants, and the waiting list control group had 91 participants. Self-report data were collected online at three timepoints: pre-test, post-test, and three-month follow-up. The primary outcome was stress recovery. Secondary outcomes included measures of perceived stress, anxiety and depression symptoms, psychological well-being, posttraumatic stress and complex posttraumatic stress symp-toms, and moral injury.Results: We found that the stress recovery intervention FOREST improved stress recovery, including psychologi-cal detachment (d = 0.83 [0.52; 1.15]), relaxation (d = 0.93 [0.61, 1.25]), mastery (d = 0.64 [0.33; 0.95]), and control (d = 0.46 [0.15; 0.76]). The effects on psychological detachment, relaxation, and mastery remained stable at the three month follow-up. The intervention was also effective in reducing its users stress (d = -0.49 [-0.80;-0.18]), anxiety symptoms (d = -0.31 [-0.62;-0.01]), depression symptoms (d = -0.49 [-0.80;-0.18]) and increasing psychological well-being (d = 0.53 [0.23; 0.84]) with the effects on perceived stress, depression symptoms, and well-being remaining stable at the three-month follow-up. High user satisfac-tion and good usability of the intervention were also reported.Conclusions: The present study demonstrated that an internet-bas ed intervention for healthcare staff could increase stress recovery skills, promote psychological well-being, and reduce stress, anxiety, and depression symptoms, with most of the effects being stable over three months.Trial registration: NCT04817995 (https://clinicaltrials.gov/ct2/show/NCT04817995).

- Quantitative assessments of prostheses performances rely more and more frequently on gait analysis focusing on prosthetic knee joint forces and moments computed by inverse dynamics. However, this method is prone to errors, as demonstrated in comparison with direct measurements of these forces and moments. The magnitude of errors reported in the literature seems to vary depending on prosthetic components. Therefore, the purposes of this study were (A) to quantify and compare the magnitude of errors in knee joint forces and moments obtained with inverse dynamics and direct measurements on ten participants with transfemoral amputation during walking and (B) to investigate if these errors can be characterised for different prosthetic knees. Knee joint forces and moments computed by inverse dynamics presented substantial errors, especially during the swing phase of gait. Indeed, the median errors in percentage of the moment magnitude were 4% and 26% in extension/flexion, 6% and 19% in adduction/abduction as well as 14% and 27% in internal/external rotation during stance and swing phase, respectively. Moreover, errors varied depending on the prosthetic limb fitted with mechanical or microprocessor-controlled knees. This study confirmed that inverse dynamics should be used cautiously while performing gait analysis of amputees. Alternatively, direct measurements of joint forces and moments could be relevant for mechanical characterising of components and alignments of prosthetic limbs.

Spin-Wave-Mode Coexistence on the Nanoscale : A Consequence of the Oersted-Field-Induced Asymmetric Energy Landscape

- It has been argued that if multiple spin wave modes are competing for the same centrally located energy source, as in a nanocontact spin torque oscillator, that only one mode should survive in the steady state. Here, the experimental conditions necessary for mode coexistence are explored. Mode coexistence is facilitated by the local field asymmetries induced by the spatially inhomogeneous Oersted field, which leads to a physical separation of the modes, and is further promoted by spin wave localization at reduced applied field angles. Finally, both simulation and experiment reveal a low frequency signal consistent with the intermodulation of two coexistent modes.

- This paper explores the building design of a Habilitation Center that promotes healthy lifestyles of people with diverse abilities. Habilitation care moves the focus of healthcare from a disease curing approach to lifelong health development. Studies show that the design of healthcare buildings can contribute to improving care and by extension, it is expected that building design can contribute to improving habilitation care. However, in practice, there is limited experience in designing habilitation facilities, particularly concerning emerging healthcare approaches such as health promotion. This paper describes the outcomes of a master thesis that was part of a pre-study for a habilitation center that focused on design strategies and solutions that stimulate physical activity for diverse users. The main research question was: In what way can building design promote active behavior for all types of building users? The study adopted a research by design approach focused on (1) understanding user needs, (2) developing design strategies, and (3) proposing a design solution. The results list several design strategies for habilitation buildings and propose how these can be implemented. These guidelines include strategies for physical movement such as indoor and outdoor exercise areas, climbing walls and access to nature. These results may support the development of the new habilitation center, while also introducing theoretical ideas and design guidelines regarding active design. The study can be used to inspire and discuss the design and development of habilitation centers specifically, and more generally healthcare buildings that adopt new care approaches such as health promotion.

- (I) We revisit the algorithmic problem of finding all triangles in a graph G= (V, E) with n vertices and m edges. According to a result of Chiba and Nishizeki (1985), this task can be achieved by a combinatorial algorithm running in O(mα) = O(m3 / 2) time, where α= α(G) is the graph arboricity. We provide a new very simple combinatorial algorithm for finding all triangles in a graph and show that is amenable to the same running time analysis. We derive these worst-case bounds from first principles and with very simple proofs that do not rely on classic results due to Nash-Williams from the 1960s. (II) We extend our arguments to the problem of finding all small complete subgraphs of a given fixed size. We show that the dependency on m and α in the running time O(αℓ-2· m) of the algorithm of Chiba and Nishizeki for listing all copies of Kℓ, where ℓ≥ 3, is asymptotically tight. (III) We give improved arboricity-sensitive running times for counting and/or detection of copies of Kℓ, for small ℓ≥ 4. A key ingredient in our algorithms is, once again, the algorithm of Chiba and Nishizeki. Our new algorithms are faster than all previous algorithms in certain high-range arboricity intervals for every ℓ≥ 7.
