Streamlining antibiotic use in community acquired pneumonia: A quality improvement initiative

Journal of Hospital Medicine, EarlyView.
Abstract Background Evidence suggests a 3‐day total duration and early transition to oral therapy is safe in hospitalized patients with community acquired pneumonia (CAP)—though such care is not standard in the United States. To implement these evidence‐based practices, a multidisciplinary group led by a hospitalist and antimicrobial stewardship ...

Dynamic Evolution and Transformative Trends in the Consumer Market: A Technology Paradox Perspective

Psychology &Marketing, EarlyView.
ABSTRACT The consumer market is defined by tensions arising from the clash between technological advancement and consumer psychology. Current research lacks a unifying framework to explain these contradictions. Addressing this gap, we introduce a conceptual model based on technology paradox theory, which maps the dynamic process from antecedents ...

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Assessing the impact of model biases on subseasonal forecast skill

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Operational all‐sky assimilation of geostationary infrared water‐vapour channels in the regional ICON‐D2 model with an ensemble Kalman filter

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Though many studies have shown potential benefit in assimilating all‐sky infrared radiances from geostationary satellites, at numerical weather prediction centres it is still common practice to assimilate clear‐sky radiances. We present the operationalization of the all‐sky assimilation of the spinning enhanced visible and infrared imager (SEVIRI ...

Sensitivity of Limited Area Atmospheric Simulations to Lateral Boundary Conditions in Idealized Experiments

Journal of Advances in Modeling Earth Systems, 2019
The goal of limited area models (LAMs) is to downscale coarse‐gridded general circulation model output to represent small‐scale features of weather and climate.

Leveraging Data-Driven Weather Models for Improving Numerical Weather Prediction Skill through Large-Scale Spectral Nudging

Weather and Forecasting
Abstract Operational meteorological forecasting has long relied on physics-based numerical weather prediction (NWP) models. Recently, this landscape has faced disruption by the advent of data-driven artificial intelligence (AI)-based weather models, which offer tremendous computational performance and competitive forecasting accuracy.

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part I: Methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the methods of the areal precipitation nowcasting system NowPrecip version 2. In this version a new methodology is introduced, which, although it shares philosophy and techniques with the original methodology of NowPrecip version 1, can be considered as distinct from that.

Utilization of satellite data in mesoscale modeling of severe weather [PDF]

The Visible Infrared Spin Scan Radiometer Atmospheric Sounder (VAS) data were used to model the 36 hour cyclogenesis period over the Pacific Ocean. Various combinations of VAS data, conventional radiosonde data, and gridded data from the National Weather

Engaging the Complexities of Energy Transitions: Sociotechnical and Dualistic Insights From Crossdisciplinary Undergraduates

Science Education, EarlyView.
ABSTRACT Discourses of energy and energy transition have become increasingly prevalent in informal and formal learning spaces. Energy transitions differ across regions, contexts, and technologies. The contextual nature of energy is an opportunity for a sociotechnical approach to its study.
