Distributed systems are often difficult to debug and understand. A typical way of gaining insight into system behavior is by inspecting execution logs. However, manual inspection of logs is an arduous process. To support this task we developed Synoptic. Synoptic outputs a concise graph representation of logged events that captures temporal invariants mined from the log. We applied Synoptic to s...

Meteorological conditions within the planetary boundary layer (PBL) are closely governed by large-scale synoptic patterns and play important roles in air quality by directly and indirectly affecting the emission, transport, formation, and deposition of air pollutants. Partly due to the lack of long-term fine-resolution observations of the PBL, the relationships between synoptic patterns, PBL st...

The objective of this project is to develop and support the capability for synoptic and pseudo synoptic data collection through simultaneous operation of multiple AUVs. The goal is to use synoptic and pseudo synoptic measurements to efficiently characterize near land shallow water and sea bottom environments. An emphasis will be placed on shallow water hydrographic survey and locating and mappi...

[1] Using the ERA-40 reanalysis data, we study the different roles of synoptic and low-frequency eddies in sustaining the latitudinal shift of the low-level baroclinicity associated with the Southern Hemisphere Annular Mode. The eddy effect is assessed through the direct eddy thermal forcing via eddy heat flux and the indirect forcing via eddy-driven mean meridional circulation (MMC). We find t...

Histological examination of the bone marrow based on an evaluation of trephine biopsies is the gold standard for the diagnosis of bone marrow involvement in non-Hodgkin’s lymphomas while immunohistochemistry and molecular analysis may increase the accuracy and the sensitivity of lymphoma detection. Subtyping lymphomas on the trephine, according to the REAL classification, needs further investig...

New accelerator mass spectrometer radiocarbon ages from gastropods in shore deposits within the pluvial Lake Chewaucan basin, combined with stratigraphical and geomorphological evidence, identify an abrupt rise and fall of lake level at ca. 12 14C ka. The lake-level high is coeval with lake-level lows in the well-dated records of palaeolakes Bonneville and Lahontan, and with a period of relativ...

This paper analyzes the relationships between northwest flow snowfall (NWFS) and various topographic and geographic (TOPO/GEOG) variables in the Southern Appalachian Mountains of the southeastern U.S. We identify NWFS events on the basis of low-level wind direction, extract values for the TOPO/GEOG variables from Digital Elevation Models (DEMs), and develop statistical relationships between NWF...

because of the passing of the air systems, temperature changes are often very sudden and plants cannot adapt themselves to these fluctuations and get damage. because low temperatures have harmful effects on the agricultural productions, so, the investigation of these temperatures are very useful for predicting and preventing probable damages. in this study, for determining the time of the freez...
