Strontium and barium isotopes in presolar silicon carbide grains measured with CHILI—two types of X grains

Geochimica Et Cosmochimica Acta, 2018
We used CHILI, the Chicago Instrument for Laser Ionization, a new resonance ionization mass spectrometer developed for isotopic analysis of small samples, to analyze strontium, zirconium, and barium isotopes in 22 presolar silicon carbide grains.

Fine-Grained Age Group Classification in the wild

2018 24th International Conference on Pattern Recognition (ICPR), 2018
Age estimation from a single face image has been an essential task in the field of human-computer interaction and computer vision which has a wide range of practical application value. Concerning the problem that accuracy of age estimation of face images under unconstrained conditions are relatively low for existing methods, we propose a method based ...

Local Contact Deflections in Grinding — Groups of Grains and Single Grains

CIRP Annals, 1986
Summary The practical significance of local contact deflections in precisian grinding operations makes them an important area of research. They are relevant not only for their direct influence on dimensional accuracy and surface finish, but also as important components in the building-up of conceptual models for closed-loop simulation of grinding ...

Fine Grained Group Gesture Detection Using Smartwatches

2019 20th IEEE International Conference on Mobile Data Management (MDM), 2019
People may perform synchronized activities in a group setting. It is helpful to provide notifications to users and also the group leader whether people are in sync. This work aims to provide this support via analyzing motion data collected from wearable devices. We collected experimental data from smart watches worn by people, applied signal processing

Report of the work group on cereal and grain crops

Plant and Soil, 1982
We have attempted to construct a general nitrogen budget for arable grain crops. There are serious gaps in our knowledge of the nitrogen cycle of grain cropping systems, and for many values we have had to rely upon rough estimates made from the best available information.

US grain group wants GM-crop tests

Trends in Plant Science, 2000
The National Grain and Feed Association said that seed companies should develop tests to enable grain handlers and processors to detect genetically modified (GM) commodities. The tests should be accurate, repeatable, low cost and applicable to future releases of biotechnology-enhanced grains and oilseeds.
