Some polynomial solutions for the non-axisymmetric Boussinesq problem
Solutions to the Boussinesq problem for the circular punch without axial symmetry can be obtained from corresponding axisymmetric solutions by parametric differentiation. The method is applied to the problem of the tilted flat punch, originally solved by Green, and to the indentation of a cylindrical surface by a flat circular punch.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42671/1/10659_2004_Article_BF00041668.pd
Qualitative systematic review of the acceptability, feasibility, barriers, facilitators and perceived utility of using physical activity in the reduction of and abstinence from alcohol and other drug use
Given the growing global increase in harm from alcohol and substance use, and the inadequacy of standard treatment to tackle the challenge, the use of physical activity (PA) interventions has received increased attention. The aim of this review is to identify common and cross cutting themes relating to how and why physical activity may impact on reduction of/abstinence from alcohol and other drug use to support future intervention design (including aspects of physical activity, barriers and facilitators, and elements of support which may have an impact). Twenty papers including qualitative data were included in the synthesis. A deductive coding framework was created and sought to identify biological, environmental and psycho-social barriers, facilitators and mechanisms of participants’ experience of engaging with physical activity interventions. Key themes supported in the evidence included how interventions influence use (e.g. reduced cravings, increases in bodily awareness and health and fitness, the development of positive focus and new identity, and increases in mood and quality of life); the impact of frequency, intensity, type, duration and timing of physical activity; perceived barriers and facilitators to engaging in physical activity (e.g. health and fitness, access and affordability, perceptions of others); and details of how much support and in what form best supports sustained changes in physical activity (e.g. social support and environment). Despite evidence being sparse, key barriers and facilitators pertinent to intervention design were identified. Recommendations for future research are indicated and the evidence promotes the need for individually tailored programmes of support for physical activity.Given the growing global increase in harm from alcohol and substance use, and the inadequacy of standard treatment to tackle the challenge, the use of physical activity (PA) interventions has received increased attention.

SCUBE3 loss-of-function causes a recognizable recessive developmental disorder due to defective bone morphogenetic protein signaling
Signal peptide-CUB-EGF domain-containing protein 3 (SCUBE3) is a member of a small family of multifunctional cell surface-anchored glycoproteins functioning as co-receptors for a variety of growth factors. Here we report that bi-allelic inactivating variants in SCUBE3 have pleiotropic consequences on development and cause a previously unrecognized syndromic disorder. Eighteen affected individuals from nine unrelated families showed a consistent phenotype characterized by reduced growth, skeletal features, distinctive craniofacial appearance, and dental anomalies. In vitro functional validation studies demonstrated a variable impact of disease-causing variants on transcript processing, protein secretion and function, and their dysregulating effect on bone morphogenetic protein (BMP) signaling. We show that SCUBE3 acts as a BMP2/BMP4 co-receptor, recruits the BMP receptor complexes into raft microdomains, and positively modulates signaling possibly by augmenting the specific interactions between BMPs and BMP type I receptors. Scube3(-/-) mice showed craniofacial and dental defects, reduced body size, and defective endochondral bone growth due to impaired BMP-mediated chondrogenesis and osteogenesis, recapitulating the human disorder. Our findings identify a human disease caused by defective function of a member of the SCUBE family, and link SCUBE3 to processes controlling growth, morphogenesis, and bone and teeth development through modulation of BMP signaling.Genetics of disease, diagnosis and treatmen
