Modeling Probabilistic Flooding in VANETs for Optimal Rebroadcast Probabilities

Probabilistic flooding is commonly considered in vehicular ad-hoc networks (VANETs) to alleviate the celebrated broadcast storm problem. Heuristics and simulations have so far proved to be an efficient way with which to design probabilistic information dissemination solutions with demonstrated effectiveness. Supplementing with mathematical analysis for both design and evaluation is expected to gen

Information Economics in the Criminal Standard of Proof

In this paper we model the criminal standard of proof as a twofold standard requiring sufficient probability of the factum probandum and sufficient informativeness. The focus of the paper is on the latter requirement, and we use decision theory to develop a model for sufficient informativeness. We demonstrate that sufficient informativeness is fundamentally a question of information economics and

Recruitment strategies and reach of a digital fall-prevention intervention for community-dwelling older adults

BACKGROUND: To have an impact on the population's health, preventive interventions have to reach a large proportion of the intended population. Digital solutions show potential for providing wider access to fall preventive exercise. However, there is a lack of knowledge about how to reach the target group. The aim of this study was to describe the recruitment process used in the Safe Step randomis

Arthroscopic partial meniscectomy vs non-surgical or sham treatment in patients with MRI-confirmed degenerative meniscus tears : a systematic review and meta-analysis with individual participant data from 605 randomised patients

Objective: To identify subgroups of patients with magnetic resonance imaging (MRI)-confirmed degenerative meniscus tears who may benefit from arthroscopic partial meniscectomy (APM) in comparison with non-surgical or sham treatment. Methods: Individual participant data (IPD) from four RCTs were pooled (605 patients, mean age: 55 (SD: 7.5), 52.4% female) as to investigate the effectiveness of APM i

Mangrove plantation suitability mapping by integrating multi criteria decision making geospatial approach and remote sensing data

Mangroves are woody plant communities that appear in tropical and subtropical regions, mainly in intertidal zones along the coastlines. Despite their considerable benefits to humans and the surrounding environment, their existence is threatened by anthropogenic activities and natural drivers. Accordingly, it is vital to conduct efficient efforts to increase mangrove plantations by identifying suit

Convergence and divergence emerging in climatic controls of polynomial trends for northern ecosystem productivity over 2000–2018

Southwest China has been the largest terrestrial carbon sink in China over the past 30 years, but has recently experienced a succession of droughts caused by high precipitation variability, potentially threatening vegetation productivity in the region. Yet, the impact of precipitation anomalies on the vegetation primary productivity is poorly known. We used an asymmetry index (AI) to explore possi

Co-occurrence of CLCN2-related leukoencephalopathy and SPG56

Family Report: Two rare autosomal recessive neurological disorders, leukoencephalopathy with ataxia and spastic paraplegia 56 (SPG56), were found in members of the same family. Two siblings presented with spastic paraplegia, cognitive impairment, bladder and bowel dysfunction and gait ataxia; their consanguineous parents were unaffected. Ophthalmological examination revealed chorioretinopathy. Bra

Resilience to Shrinking as a Catch-Up Strategy : a Comparison of Brazil and Indonesia, 1964–2019

Development economics has long focused on growth patterns to explain countries’ ability to catch up and forge ahead. We argue, however, that resilience to economic shrinking matters more. Using the examples of Brazil and Indonesia, we propose that a framework consisting of social capabilities—namely structural transformation, autonomy, and inclusion—can explain why Indonesia is more resilient to e
