Dial a Ride from k-forest

open access: yes, 2007
The k-forest problem is a common generalization of both the k-MST and the dense-$k$-subgraph problems. Formally, given a metric space on $n$ vertices $V$, with $m$ demand pairs $\subseteq V \times V$ and a ``target'' $k\le m$, the goal is to find a ...

Three-axis attitude and direction reference instrument has only one moving part [PDF]

open access: yes, 1966
Lunar vehicle instrument combines the functions of attitude reference, direction reference, and display in a unit having only one moving part. The device, using bubble levels and a calibrated dial, is used as a sextant prior to takeoff, and as a backup ...

Nd:Glass-Raman laser for water vapor dial [PDF]

open access: yes, 1986
A tunable solid-state Raman shifted laser which was used in a water vapor Differential Absorption Lidar (DIAL) system at 9400 A is described. The DIAL transmitter is based on a tunable glass laser operating at 1.06 microns, a hydrogen Raman cell to shift

Litsea cubeba Essential Oil Reduces Postharvest Blueberry Rot by Inducing Cell Membrane Damage and Reactive Oxygen Species Accumulation in Alternaria alternata

open access: yesFuture Postharvest and Food, EarlyView.
Litsea cubeba essential oil (LCEO) reduces blueberry rot while maintaining quality. It disrupts the cellular structure and membranes of Alternaria alternata, causing solute leakage, while simultaneously inducing reactive oxygen species (ROS) accumulation and mitochondrial membrane potential (MMP) damage in the pathogen.
