Good hygiene, in both health care and the community, is central to containing the rise of antibiotic resistance, as well as to infection control more generally. But despite the well-known importance, the ecological mechanisms by which hygiene (or other transmission control measures) affect the evolution of resistance remain to be elucidated. Using metacommunity ecology theory, we here propose that

Dynamic heterogeneity in lung ventilation is an important measure of pulmonary function and may be characteristic of early pulmonary disease. While standard indices like spirometry, body plethysmography, and blood gases have been utilized to assess lung function, they do not provide adequate information on regional ventilatory distribution nor function assessments of ventilation during the respira

The role of time-dependent freezing of ice nucleating particles (INPs) is evaluated with the “Aerosol–Cloud” (AC) model in 1) deep convection observed over Oklahoma during the Midlatitude Continental Convective Cloud Experiment (MC3E), 2) orographic clouds observed over North California during the Atmospheric Radiation Measurement (ARM) Cloud Aerosol Precipitation Experiment (ACAPEX), and 3) super

Hanteringen av stallgödsel i jordbruket orsakar en stor del av utsläppen av ammoniak i Sverige. För att uppnå Sveriges mål om att minska utsläppen av ammoniak behöver jordbrukare utföra åtgärder som minskar utsläppen av ammoniak. Samtidigt är det viktigt att ta hänsyn till hur åtgärder som minskar ammoniakutsläppen också kan bidra till att minska utsläpp av växthusgaserna metan och lustgas. Här di

This paper presents a development of the use of multi-axial ultrasonic data for the quantification of extrinsic, crack or grain-contact induced elastic anisotropy in core samples with application to a UKCS oil field. An approach for inversion of multi-axial velocity measurements is presented, which extends the previous work by Sayers (2002) for the determination of second- and fourth-order crack d

Two frameworks are proposed for extremum seeking of general nonlinear plants based on a sampled-data control law, within which a broad class of nonlinear programming methods is accommodated. It is established that under some generic assumptions, semi-global practical convergence to a global extremum can be achieved. In the case where the extremum seeking algorithm satisfies a stronger asymptotic s

In strategic management, the concept of organizational capabilities appears in two sets of related literatures: the resource-based view and the dynamic capabilities approach. The resource-based view treats organizational capabilities as unitary factors that explain cross-sectional industry performance differentials. The dynamic capabilities approach, on the other hand, treats organizational capabi
