• #### Frozen Lake Baikal - Russia ﻿

(1909)
In 1908, the Rice Institute Board of Trustees sent their newly chosen President, Edgar Odell Lovett, on a world tour seeking out the best aspects of the leading colleges and universities. Dr. and Mrs. Lovett traveled in ...
• #### Frugivores bias seed-adult tree associations through nonrandom seed dispersal: a phylogenetic approach ﻿

(2016)
Frugivores are the main seed dispersers in many ecosystems, such that behaviorally driven, nonrandom patterns of seed dispersal are a common process; but patterns are poorly understood. Characterizing these patterns may ...
• #### A Fruit Shop in the Water-Melon Season. ﻿

• #### Frustration in biomolecules ﻿

(2014)
Biomolecules are the prime information processing elements of living matter. Most of these inanimate systems are polymers that compute their own structures and dynamics using as input seemingly random character strings of ...

• #### FT-ICR studies of gallium arsenide cluster ions ﻿

(1992)
Gallium arsenide clusters have been studied on a Fourier transform ion cyclotron resonance(FT-ICR) mass spectrometer with an external supersonic cluster source. Reaction of GaAs cluster cations with ammonia revealed that ...
• #### FT-ICR studies of gas phase silicon cluster ion reactivity and a new model for predicting the structure of silicon clusters ﻿

(1990)
A new apparatus capable of combining an external laser vaporization supersonic cluster beam source with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer has been designed and implemented. Cluster ions ...
• #### FT-ICR studies of giant carbon fullerenes ﻿

(1992)
FT-ICR studies of high mass $\rm (C\sb{>150})$ carbon clusters have brought insight to the controversial structures of carbon fullerenes. Laser vaporization followed by supersonic beam technique produced carbon clusters ...

• #### Fuchsian groups and polygonal billiards ﻿

(1996)
Let P be a simple, closed polygon in the plane, all interior angles of which are rational multiples of $\pi$. We consider the possible paths of a point, rebounding in the interior of P with constant speed and elastic ...
