The Effects of Refractive Index Mismatch on Multiphoton Fluorescence Excitation Microscopy of Biological Tissue
scattering spherical aberration refractive index mismatch two-photon microscopy multiphoton fluorescence excitation microscopy
2015/5/21
Introduction: Multiphoton fluorescence excitation microscopy (MPM) is an invaluable tool for studying processes in tissue in live animals by enabling biologists to view tissues up to hundreds of micro...
Defending The Fallacy of Fine-Tuning
Defending Fallacy Fine-Tuning Cosmology and Extragalactic Astrophysics
2012/2/21
In 2011, I published a popular-level book, The Fallacy of Fine-Tuning: Why the Universe is Not Designed for Us. It investigated a common claim found in contemporary religious literature that the param...

IS THE “STAR TREK”CONCEPT OF ALIENS REALLY NAIVE? -- A COMMENT ON DURIC AND FIELD
Astrobiology-Extraterrestrial intelligence-Radio lines general-Galaxy stellar content
2009/3/6
Several assumptions used in the recent review paper on the search
for extraterrestrial intelligence (SETI) by Duric and Field (2003) are critically dis-
cussed. New astrobiological results|in partic...
One of the most interesting problems in the nascent discipline
of astrobiology is more than half-century old Fermi's paradox: why, considering
extraordinary young age of Earth and the Solar System i...

2009/2/11
We investigate the e®ects of correlated global regulation mecha-
nisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution
of hypothetical inhabited planets, using simple ...
EVIDENCE OF MOLECULAR ADAPTATION TO EXTREME ENVIRONMENTS AND APPLICABILITY TO SPACE ENVIRONMENTS
Astrobiology
2009/2/9
This is initial investigation of gene signatures responsible for adapt-
ing microscopic life to the extreme Earth environments. We present preliminary
results on identi¯cation of the clusters o...

Astrobiology-methods numerical-Galaxy evolution-extraterres-trial intelligence
2009/2/9
The number and distribution of habitable planets in the Milky
Way is one of the foremost problems of contemporary astrobiological research. We
investigate the e®ects of applying general neocatas...
