Rapid Increase in Soil Respiration and Reduction in Soil Nitrate Availability Following CO Enrichment in a Mature Oak Forest.

In the future, with elevated atmospheric CO (eCO), forests are expected to increase woody biomass to capture more carbon (C), though this is dependent on soil nutrient availability. While young forests may access unused nutrients by growing into an unexplored soil environment, it is unclear how or if mature forests can adapt belowground under eCO. Soil respiration ( ) and nutrient bioavailability are integrative ecosystem measures of below-ground dynamics.

Recovery model for minimally invasive central cannulation, cardiopulmonary bypass, and cardioplegic arrest in quadrupeds.

Sternotomy is rarely performed for veterinary therapeutic or recovery models in quadrupeds because of difficulties with breathing, ambulation, and pain control. Central cannulation for cardiopulmonary bypass (CPB) is infrequent and typically performed through full thoracotomies. Experienced clinical surgeons and perfusionists should provide guidance for new therapeutic interventions and translational research.

Feasibility of controlled nitric oxide generation ascorbate induced chemical reduction of nitrite ions.

Inhalable nitric oxide (iNO) is a lifesaving, FDA-approved drug to improve oxygenation in persistent pulmonary hypertension of the newborn. iNO also has many other applications in lung diseases owing to its vasodilatory and antimicrobial effects. However, its wider therapeutic application is often prohibited by the high cost and logistical barriers of traditional NO/N gas tanks.

An "ultimate" coupled cluster method based entirely on T2.

Electronic structure methods built around double-electron excitations have a rich history in quantum chemistry. However, it seems to be the case that such methods are only suitable in particular situations and are not naturally equipped to simultaneously handle the variety of electron correlations that might be present in chemical systems. To this end, the current work seeks a computationally efficient, low-rank, "ultimate" coupled cluster method based exclusively on T2 and its products that can effectively emulate more "complete" methods that explicitly consider higher-rank, T2m, operators.
