The effective adhesive properties of heterogeneous thin films are characterized through a combined experimental and theoretical investigation. By bridging scales, we show how variations of elastic or adhesive properties at the microscale can significantly affect the effective peeling behavior of the adhesive at the macroscale. Our study reveals three elementary mechanisms in heterogeneous syste...

The stability of networks is greatly influenced by their degree distributions and in particular by their breadth. Networks with broader degree distributions are usually more robust to random failures but less robust to localized attacks. To better understand the effect of the breadth of the degree distribution we study two models in which the breadth is controlled and compare their robustness a...

We experimentally demonstrate the broad tunability of the main features of optical localized structures (LS's) in a nonlinear interferometer. By discussing how a single LS depends on the system spatial frequency bandwidth, we show that a modification of its tail leads to the possibility of tuning the interactions between LS pairs, and thus the equilibrium distances at which LS bound states form...

Objective(s) The objective of this study was to document and explain bilateral differences in the Q angle. Materials and Methods Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with res...

DNA exhibits a remarkable mechanical transition where its extension increases by 70% at 65 pN. Notwithstanding more than a decade of experimental and theoretical studies, there remains a significant debate on the nature of overstretched DNA. We developed a topologically closed but rotationally unconstrained DNA assay, which contains no nicks or free ends. DNA in this assay exhibited the canonic...

The use of calcium sulfate beads (CSBs) as a carrier for local delivery antibiotics is increasingly reported the treatment localized infections. They are used most commonly in bone and joint infections, post-trauma diabetes-related foot wounds, vascular grafts. Hypercalcemia rarely with CSB but an important safety concern, patients at higher risk should be identified prospectively followed care...
