Hydrodynamic lift forces offer a convenient way to manipulate particles in microfluidic applications, but there is little quantitative information on how non-inertial lift mechanisms act and compete with each other in the confined space of microfluidic channels. This paper reports measurements of lift forces on nearly spherical drops and bubbles, with diameters from one quarter to one half of t...

BACKGROUND Functional Capacity Evaluations (FCEs) are routinely used in physical medicine to ascertain an individual's work ability; with lift capacity being an important aspect of many evaluations. Despite the widespread use of lift capacity tests, there are few studies that provide age and gender normative data. OBJECTIVE To evaluate the safety, reliability, and validity of the EPIC Lift Ca...

BACKGROUND Although early secondary face lift is a highly scrutinized procedure, it is beneficial for a select group of patients. Justification for performing the early secondary face lift or staged face lift is more apparent when considering the biomechanical limitations of the primary face lift. METHODS All patients undergoing primary face-lift procedures performed by the senior author (T.A...

The present study aimed at assessing a novel annular-ducted fan lift system for VTOL aircraft through computational fluid dynamics (CFD) simulations. The power and lift efficiency of the lift fan system in hover mode, the lift and drag in transition mode, the drag and flight speed of the aircraft in cruise mode and the pneumatic coupling of the tip turbine and jet exhaust were studied. The resu...

In vivo fluoroscopic studies of patients with total knee replacements (TKRs) have shown lift-off of the femoral condyles from the tibial insert. This study investigated the influence of femoral condylar lift-off on the ultra-high molecular weight polyethylene (UHMWPE) wear of fixed bearing (FB) and rotating platform mobile bearing (RP MB) total knee replacements, using a physiological knee join...

section, a composite (deep-plane) rhytidectomy, and a subperiosteal face-lift. The results showed that the separate subcutaneous and sub-SMAS dissection interrupts the rich continuous anastomotic network between all these vessels. Arterial continuity is best maintained with the composite lift and the subperiosteal face-lift. The most significant arterial contribution of the face-lift flap is fr...

We consider the Kudla-Millson lift from elliptic modular forms of weight (p + q)/2 to closed q-forms on locally symmetric spaces corresponding to the orthogonal group O(p, q). We study the L-norm of the lift following the Rallis inner product formula. We compute the contribution at the Archimedian place. For locally symmetric spaces associated to even unimodular lattices, we obtain an explicit ...
