Hip morphology‐based osteoarthritis risk prediction models: development and external validation using individual participant data from the World COACH Consortium

Arthritis Care &Research, Accepted Article.
Objectives This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the World COACH consortium ...

Inversion Symmetry and Critical Exponents of Dissipating Waves in the Sandpile Model

, 1999
Statistics of waves of topplings in the Sandpile model is analysed both analytically and numerically. It is shown that the probability distribution of dissipating waves of topplings that touch the boundary of the system obeys power-law with critical ...

Mapped Exponent and Asymptotic Critical Exponent of Words

We study how much injective morphisms can increase the repetitiveness of a given word. This question has a few possible variations depending on the meaning of ``repetitiveness''. We concentrate on fractional exponents of finite words and asymptotic critical exponents of infinite words.

Identifying High‐Impact Solutions to Address Racial and Ethnic Health Disparities in Lupus: A Consensus‐Based Approach

Arthritis Care &Research, Accepted Article.
Objective We conducted formative research aimed at identifying solutions that address inequitable health outcomes in lupus due to adverse social determinants of health. Methods We conducted a search for keywords which provided insights into potential solutions and initiatives underway. An advisory panel of lupus experts iteratively reviewed the list of

The Method of Exponent Pairs [PDF]

Acta Arithmetica, 1985
This is a refinement of the author's earlier paper in [Topics in classical number theory, Vol. II, Colloq. Math. Soc. János Bolyai 34, 907-926 (1984; Zbl 0552.10022)]. The following important consequences of the new results are mentioned \[ \zeta (+it)\leq t^{139/858+\epsilon},\quad \Delta (R)\leq R^{139/429+\epsilon}. \]

The impact of positive lifestyle behaviors on direct healthcare cost savings for low back pain

Arthritis Care &Research, Accepted Article.
Objective This study aimed to investigate the relationship between a previously purpose‐developed lifestyle behavior scale and healthcare cost savings related to low back pain (LBP). Methods This longitudinal study utilised data from the AUstralian Twin BACK (AUTBACK) study. LBP and lifestyle behavior measures were collected at baseline.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

The complexity of biomechanics causing primary blast-induced traumatic brain injury: a review of potential mechanisms.

Frontiers in Neurology, 2015
Primary blast induced traumatic brain injury (bTBI) is a prevalent battlefield injury in recent conflicts, yet biomechanical mechanisms of bTBI remain unclear.

3D In Vitro Models of Breast Cancer: Current Challenges and Future Prospects Toward Recapitulating the Microenvironment and Mimicking Key Processes

Advanced Biology, EarlyView.
In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.
