Optimal quantum adversary lower bounds for ordered search

open access: yes, 2007
The goal of the ordered search problem is to find a particular item in an ordered list of n items. Using the adversary method, Hoyer, Neerbek, and Shi proved a quantum lower bound for this problem of (1/pi) ln n + Theta(1).

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation

open access: yesPolymer Composites, EarlyView.
Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

Histochemical Study of the Progenetic Trematode Alloglossidium renale

open access: yesJournal of Parasitology Research, 2014
A histochemical study of the progenetic trematode Alloglossidium renale has demonstrated the absence of any secreted material between the adult worm and the host (freshwater shrimp) antennal gland tubules. Host tissue is affected only by the compression,

Is It Already May? [PDF]

open access: yes, 2012
Last week of classes and one week of exams—the semester is slowly winding down, and soon, if the weather cooperates, summer will be here. In the meantime, for most of us on campus it’s time to buckle down and do the work we’ve all been procrastinating on.

Minimally invasive sacroiliac joint fusion: Primary endpoint results from the prospective, multicenter STACI study

open access: yesPM&R, EarlyView.
Abstract Background Chronic sacroiliac joint (SIJ) pain is highly debilitating. Minimally invasive SIJ fusion has become a commonly performed surgical treatment for SIJ pain, with level I evidence showing clinically significant improvements in pain, function, and quality of life and a low adverse event rate.

Optoelectronic control of surface plasmon polaritons at metal-doped semiconductor interfaces

open access: yesJPhys Photonics
We present a metal–semiconductor (M–S) based electro-optic modulator designed for functional plasmonic circuits, utilizing the active control of surface plasmon polaritons (SPPs) at M–S junction interfaces.

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...
