The Many Streams of the Magellanic Stream [PDF]

The Astrophysical Journal, 2008
AbstractAs a part of the ongoing H i survey by the consortium for Galactic studies with the Arecibo L-band Feed Array (GALFA-HI), we have recently imaged the tip of the MS and found several long filamentary structures. This demonstrates that the northern portion of the MS, which has been interacting with the Galactic halo for a long time, is more ...

Ordering in bidirectional pedestrian flows and its influence on the fundamental diagram

, 2012
Experiments under laboratory conditions were carried out to study the ordering in bidirectional pedestrian streams and its influence on the fundamental diagram (density-speed-flow relation). The Voronoi method is used to resolve the fine structure of the

Modeling the gravitational potential of a cosmological dark matter halo with stellar streams [PDF]

, 2016
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the host system. We select and study narrow stellar streams formed in a Milky-

Development and validation of an alternative method for ergosterol determination in alder leaves using liquid-liquid extraction and LC-MS/MS after saponification

MethodsX
Ergosterol is widely used as proxy for the estimation of leaf litter associated fungal biomass. According to a common textbook method, ergosterol can be extracted from plant tissue with methanolic potassium hydroxide followed by purification with solid ...

Horticulture affects macroinvertebrate assemblages in adjacent streams (Buenos Aires, Argentina)

Knowledge and Management of Aquatic Ecosystems, 2020
The agrochemicals used on crops can reach watercourses, affecting water quality and biologic communities. The aim of this research was to study the effects of horticulture on the water quality and invertebrate assemblages of adjacent streams in Buenos ...

Transmission protocols for instruction streams [PDF]

, 2009
Threads as considered in thread algebra model behaviours to be controlled by some execution environment: upon each action performed by a thread, a reply from its execution environment -- which takes the action as an instruction to be processed ...

Streaming kidney

Cell Proliferation, 1991
Abstract. Twenty‐five male young adult random bred rats, weighing 250–300 g, were injected with 18·5 kBq/g body weight tritiated thymidine (specific activity 185 GBq/mM). The rats were then killed in groups of five, at the following times: 1 h and14, 30, 60 and 120 days.

Stellar Streams as Probes of Dark Halo Mass and Morphology: A Bayesian Reconstruction

, 2011
Tidal streams provide a powerful tool by means of which the matter distribution of the dark matter halos of their host galaxies can be studied. However, the analysis is not straightforward because streams do not delineate orbits, and for most streams ...

Growth and population dynamics of crayfish Paranephrops planifrons in streams within native forest and pastoral land uses [PDF]

, 2002
Population dynamics of crayfish (Paranephrops planifrons White) in streams draining native forest and pastoral catchments, Waikato, New Zealand, were investigated from September 1996 to July 1998.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
