BACKGROUND CONTEXT: Multilevel fusions, the use of allograft bone, and smoking have
been associated with an increased risk of nonunion after anterior cervical discectomy and …

Background Transforaminal lumbar interbody fusion (TLIF) with grafting and implant options
like iliac crest bone graft (ICBG), recombinant bone morphogenetic protein (rhBMP), and …

Safe spine surgery is possible during the COVID-19 pandemic. Certain urgent procedures
must still be performed during this challenging time to prevent permanent long-term disability …

Background The Connecticut Orthopaedic Institute (COI) conceptualized a Pivot Plan during
an elective surgery moratorium at the beginning of the severe acute respiratory syndrome …

Stromal cells of the bone marrow control the development of osteoclasts through the production
of cytokines capable of promoting the proliferation and differentiation of hematopoietic …

An experimental set‐up has been designed to record maps of intensity distribution for two
orthogonal polarizations allowing the retrieval of average information along the optical path. A …

The four-flux model for multiple scattering media allows one to evaluate scattering properties
(reflectances, transmittances) by using simple formulae which may even be readily handled …

The scattering of a finite beam by an ensemble of infinite cylinders, with a spatial orientation
function of the depth, is simulated by using a Monte Carlo type code, including multiple …

With an enough short-pulse incident to an individual particle, elementary scattering modes
can be observed: internal or external reflection, refraction and diffraction. Simulation of pulse …

The influence of particles on the first Rayleigh–Bénard bifurcation from the motionless to the
convective state has been studied in a suspension layer heated from below and cooled from …
