Variation of Hodge structure for generalized complex manifolds
Variation of Hodge structure generalized complex manifolds Differential Geometry
2012/5/9
A generalized complex manifold which satisfies the $\partial \overline{\partial}$-lemma admits a Hodge decomposition in twisted cohomology. Using a Courant algebroid theoretic approach we study the be...
Temporal variation of 134Cs and 137Cs activities in surface water at stations along the coastline near the Fukushima Dai-ichi Nuclear Power Plant accident site, Japan
radiocaesium ocean coast Fukushima geochemistry
2017/4/11
We present our April to December 2011 observations of 134Cs and 137Cs activities in surface water at Hasaki, a coastal

Mitochondrial sequence variation suggests extensive cryptic diversity within the Western Palearctic Daphnia longispina complex
Mitochondrial sequence variation extensive cryptic diversity the Western Palearctic Daphnia longispina complex
2014/4/4
We report on a discovery of six divergent lineages within the European Daphnia longispina complex from various localities in central to northeast Europe. The levels of divergence from well-known speci...
FunctionaL Regular Variation of Levy-driven Multivariate Mixed Moving Average Processes

Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics
2012/4/19
We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...
Annual Variation of Local Photon Emissions’ Spectral Power within the mHz Range Overlaps with Seismic-Atmospheric Acoustic Oscillations
Photon Emissions Earth Oscillations Spheroidal Modes
2013/3/7
Spheroidal modes of seismic and acoustic oscillations in the atmosphere occur within the 2 to 7 mHz range with peak-to-peak variations in the order of 10–12 to 10–11 m·s–2. Previous research indicated...
Multi-Satellite and Sensor Derived Trends and Variation of Snow Water Equivalent on the High-Latitudes of the Northern Hemisphere
Arctic Snow Water Equivalent Multi-Satellite Microwave Trends and Variations
2013/3/7
Utilizing more than 30 years of satellite-microwave sensor derived snow water equivalent data on the high-latitudes of the northern hemisphere we investigate regional trends and variations relative to...
Order parameter fluctuations in natural time and b-value variation before large earthquakes
Order parameter fluctuations natural time b-value variation large earthquakes Geophysics
2012/5/29
Self-similarity may stem from two origins: the process' increments infinite variance and/or process' memory. The $b$-value of the Gutenberg-Richter law comes from the first origin. In the frame of nat...

2015/12/10
Social insects exhibit coordinated behaviour without central control. Local interactions
among individuals determine their behaviour and regulate the activity of the colony.Harvester ants are recruit...
The coercivity of amorphous rate earth-transition metal magneto-option (MO) recording media has been measured as a function of position on the films utilizing a micro-Kerrhysteresis-loop-tracer with a...
