We present a theoretical study of the effect of weak anchoring on the transition between C1 and C2 chevron structures in smectic C liquid crystals. We employ a continuum theory which allows for variable cone, azimuthal and layer tilt angles. Equilibrium profiles for the director cone and azimuthal angles in the C1 and C2 states are calculated from the standard Euler-Lagrange minimisation of the...
Background Surgical correction for hallux valgus (HV) has been demonstrated to be effective compared with watchful waiting and orthotic therapy, and improves the quality of life of individuals with HV. The severity of the HV deformity generally dictates the type of procedure choice, and it is generally considered that the scarf osteotomy affords a greater reduction of the 1-2 intermetatarsal an...

BACKGROUND Atrial tachycardias (AT) during or after ablation of atrial fibrillation frequently pose a diagnostic challenge. We hypothesized that both the patterns and the timing of coronary sinus (CS) activation could facilitate AT mapping. METHODS AND RESULTS A total of 140 consecutive postpersistent atrial fibrillation ablation patients with sustained AT were investigated by conventional ma...
Aims and background: Low back pain is a common ailment that affects about 80% of the population at some point in their life time. Using a brace is a method to control pain that physiotherapists recommend it. However, the scientific evidence about the effects of different braces in low back pain patients is limited. Therefore, the aim of this study was to evaluate the effects of two thoracol...
Knee bracing has been used to realize a variety of functional outcomes in both sport and rehabilitation application. Much of the literature focuses on the effect of knee misalignment, force reduction and superiority of custom braces over commercial over-the-counter braces. Efforts on developing exoskeletons to serve as knee augmentation systems emphasize actuation of joints, which then adds to ...
The influence of law on the orthodontic profession has greatly increased in the last few decades. Dental law has emerged today as a full-fedged specialty dealing with a variety of areas, like professional negligence, doctor-patient contracts, consumer protection laws, ethics, general and special health legislations and practice regulatory mechanisms. This article highlights the concept of infor...
