In 1998, the Mars Orbiter Laser Altimeter revealed the presence of isolated or quasi-periodic thick clouds during the martian polar night. They are believed to be composed of CO2 ice particles and to be tilted against the wind direction, a feature characteristic of vertically propagating orographic gravity waves. To support that interpretation, we present here numerical simulations with a two-d...

The recent deployment of the Atmospheric Radiation Measurement Program (ARM) Mobile Facility at Graciosa Island, Azores, in the context of the Clouds, Aerosol and Precipitation in theMarine Boundary Layer (CAP-MBL) field campaign added the most extensive (19 months) and comprehensive dataset of marine boundary layer (MBL) clouds to date. Cloud occurrence is high (60%–80%), with a summertime min...

Federated learning (FL) enables distribution of machine workloads from the cloud to resource-limited edge devices. Unfortunately, current deep networks remain not only too compute-heavy for inference and training on devices, but also large communicating updates over bandwidth-constrained networks. In this paper, we develop, implement, experimentally validate a novel FL framework termed Dynamic ...

The CAP theorem establishes that a cloud service can only guarantee two of {Consistency, Availability and Partition Tolerance}, motivating developers to reject transactional ACID properties. Instead, they use BASE: a methodology whereby one transforms an application into a faster and more scalable version by running it as a series of asynchronous steps that each use local data replicas (even if...

BACKGROUND/AIMS It is unclear whether the endoscopic features of sessile serrated adenomas (SSAs) would be useful to trainee colonoscopists to predict SSA. Therefore, the present study aimed to identify features that expert and trainee colonoscopists can use to independently and reliably predict SSA by using high-resolution white-light endoscopy. METHODS Endoscopic images of 81 polyps (39 SSA...

[1] Precipitation over and near mountains is not caused by topography but, rather, occurs when storms of a type that can occur anywhere (deep convection, fronts, tropical cyclones) form near or move over complex terrain. Deep convective systems occurring near mountains are affected by channeling of airflow near mountains, capping of moist boundary layers by flow subsiding from higher terrain, a...
