Some Aspects of Printing Quality [PDF]
, 1959 The object of this experiment was to find the effect of various pressures upon the ink coverage and the visual appearance of the half-tone print. A specially designed plate with four evenly spaced elevations was used with a Vandercook proof press ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Constrained Heterogeneous Vehicle Path Planning for Large-area Coverage [PDF]
IEEE/RJS International Conference on Intelligent RObots and Systems, 2019 There is a strong demand for covering a large area autonomously by multiple UAVs (Unmanned Aerial Vehicles) supported by a ground vehicle. Limited by UAVs’ battery life and communication distance, complete coverage of large areas typically involves ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Extracellular polymeric bacterial coverages as minimal area surfaces [PDF]
Journal of Colloid and Interface Science, 2006 Surfaces formed by extracellular polymeric substances enclosing individual and some small communities of {\it Acidithiobacillus ferrooxidans} on plates of hydrophobic silicon and hydrophilic mica are analyzed by means of atomic force microscopy imaging. Accurate nanoscale descriptions of such coverage surfaces are obtained.

Oyster Bed Mapping in the Great Bay Estuary, 2012-2013 [PDF]
, 2013 Six major oyster beds (reefs) in New Hampshire are mapped periodically to assess wild oyster populations in the Great Bay Estuary. Data on the spatial extent of the beds are combined with density and other measures to estimate the abundances of live ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

On Multi-robot Area Coverage [PDF]
, 2010 Area coverage is one of the emerging problems in multi-robot coordination In this task a team of robots is cooperatively trying to observe or sweep an entire area, possibly containing obstacles, with their sensors or actuators The goal is to build an efficient path for each robot which jointly ensure that every single point in the environment can be ...
