The longitudinal aerodynamics of micro aerial vehicles, although not fully understood, have been the subject of several studies in recent years; however, littleworkhasbeendone to investigate the lateral loading. In this experiment, flat-plate wings with rectangular planforms of aspect ratios AR 0.75, 1, 1.5, and 3 and tapered planforms of λ 0.75, 0.5, and 0.25 were placed in the wind tunnel at ...

Apoptosis evasion is a hallmark of human cancer. PUMA is a BH3-only Bcl-2 family protein that mediates both p53-dependent and independent apoptosis. However, its role in tumor suppression had not been well established. Our recent work provides direct evidence that PUMA plays an important role in suppressing intestinal tumorigenesis in two mouse models including (i) the azoxymethane (AOM)/dextra...

Vertical-axis wind turbines (VAWT) are excellent candidates to complement traditional and increase the total energy capacity. Development of VAWT has been hampered by their low efficiency structural unreliability, which related occurrence dynamic stall. Dynamic stall consists formation, growth, shedding large-scale vortices, followed massive flow separation. The vortex is detrimental turbine's ...

A University of Wisconsin-Madison lameness survey was carried out on 30 well recorded dairy herds – 15 stanchion/tie-stall and 15 free-stall, with a variety of stall bases. Each herd was visited twice – once in the spring/summer of 2000 and once in the winter of 2001. On both occasions, all milking cows were locomotion scored 1 through 4 with cows scoring 3 or 4 classified as lame. The proporti...

Fuel cell gas turbine hybrid systems have achieved ultra-high efficiency and ultra-low emissions at small scales, but have yet to demonstrate effective dynamic responsiveness or base-load cost savings. Fuel cell systems and hybrid prototypes have not utilized controls to address thermal cycling during load following operation, and have thus been relegated to the less valuable base-load and peak...

Over-the-top mobile video streaming is invariably influenced by volatile network conditions which cause playback interruptions (stalling events), thereby impairing users’ quality of experience (QoE). Developing models that can accurately predict users’ QoE could enable the more efficient design of quality-control protocols for video streaming networks that reduce network operational costs while...

Rupture of the peroneous tertius was diagnosed in a 7-year-old stallion, based on clinical examinations.The stifle joint flexed as the limb was advanced forward without flexing the hock. When the limb was pulledbackward, the hock joint extended but the stifle was in the normal position. The recommended treatmentincluded complete stall rest for 6 weeks followed by limited exercise for 2 months. ...

This paper presents in-flight measurements of the interaction wing wake a stalled Slingsby T67 Firefly light aircraft with tailplane. Tailplane data was recorded by GoPro360 camera and analyzed using spatial correlation methods. The tailplane movement corresponding spectra indicate that aerodynamic shedding frequency closely matches resonant tailplane, resulting in significant excitation struct...

Fast set-associative level-one data caches (L1 DCs) access all ways in parallel during load operations for reduced access latency. This is required in order to resolve data dependencies as early as possible in the pipeline, which otherwise would suffer from stall cycles. A significant amount of energy is wasted due to this fast access, since the data can only reside in one of the ways. While it...

Skeletal muscle's ability to shorten and lengthen against a load is a fundamental property, presumably reflecting the inherent load-dependence of the myosin molecular motor. Here we report the velocity of a single actin filament translocated by a mini-ensemble of skeletal myosin approximately 8 heads under constant loads up to 15 pN in a laser trap assay. Actin filament velocity decreased with ...
