How cortical waves drive fission of motile cells [PDF]

open access: yes, 2020
Cytokinesis—the division of a cell into two daughter cells—is a key step in cell growth and proliferation. It typically occurs in synchrony with the cell cycle to ensure that a complete copy of the genetic information is passed on to the next generation ...

Size of the group IVA iron meteorite core: Constraints from the age and composition of Muonionalusta

open access: yes, 2011
The group IVA fractionally crystallized iron meteorites display a diverse range of metallographic cooling rates. These have been attributed to their formation in a metallic core, approximately 150 km in radius, that cooled to crystallization in the ...

A structure from the sixth millennium cal BC with no artifactual content at San Quirce (Palencia, Spain): a multidisciplinary study [PDF]

open access: yes, 2019
During the course of the excavations of the San Quirce open-air archaeological site in Spain, an unusual negative structure was identified in the Holocene level dated ca. sixth millennium cal BC.

アサクサノリの粗繊維分解酵素 [PDF]

open access: yes, 1984
Enzymes secreted from the bacteria isolated from cultured nori (Porphyra sp.) infected with Anaaki-disease digested the crude fiber isolated from Porphyra. Bacteria, two strains of P4 and P5, were identified as Vibrio fisheri by taxonomic studies.

Estimating the health impact of air pollution in Scotland, and the resulting benefits of reducing concentrations in city centres [PDF]

open access: yes, 2019
Air pollution continues to be a key health issue in Scotland, despite recent improvements in concentrations. The Scottish Government published the Cleaner Air For Scotland strategy in 2015, and will introduce Low Emission Zones (LEZs) in the four major ...

Applying Nyquist’s method for stability determination to solar wind observations [PDF]

open access: yes, 2017
The role instabilities play in governing the evolution of solar and astrophysical plasmas is a matter of considerable scientific interest. The large number of sources of free energy accessible to such nearly collisionless plasmas makes general modeling ...

Reliability of resistivity quantification for shallow subsurface water processes

open access: yes, 2009
The reliability of surface-based electrical resistivity tomography (ERT) for quantifying resistivities for shallow subsurface water processes is analysed. A method comprising numerical simulations of water movement in soil and forward-inverse modeling of

Lateral distribution functions for giant air showers [PDF]

open access: yes, 2002
We have compared the lateral analytical structure functions coming from cascade theory to the numerical distributions generated by EAS Monte Carlo simulations and to the empirical functions used in giant air showers experiments. Introducing the Gaussian
