Fertilizer Practices for Bromegrass
Smooth Bromegrass (Bromus inennis Leyss.) is the dominant
and mos t dependable perennial forage crop grown in Alaska. Preliminary
studies of the influence of fertilizers upon crude protein
yields of bromegrass in Alaska were reported in 1953 ( 5) .1 Several
additional fertilizer experiments on bromegrass stands established from
northern-grown commercial seed have been conduct ed from 1952 to 196 0
and are reported here

The Random Walk of High Frequency Trading
This paper builds a model of high-frequency equity returns by separately
modeling the dynamics of trade-time returns and trade arrivals. Our main
contributions are threefold. First, we characterize the distributional behavior
of high-frequency asset returns both in ordinary clock time and in trade time.
We show that when controlling for pre-scheduled market news events, trade-time
returns of the highly liquid near-month E-mini S&P 500 futures contract are
well characterized by a Gaussian distribution at very fine time scales. Second,
we develop a structured and parsimonious model of clock-time returns by
subordinating a trade-time Gaussian distribution with a trade arrival process
that is associated with a modified Markov-Switching Multifractal Duration
(MSMD) model. This model provides an excellent characterization of
high-frequency inter-trade durations. Over-dispersion in this distribution of
inter-trade durations leads to leptokurtosis and volatility clustering in
clock-time returns, even when trade-time returns are Gaussian. Finally, we use
our model to extrapolate the empirical relationship between trade rate and
volatility in an effort to understand conditions of market failure. Our model
suggests that the 1,200 km physical separation of financial markets in Chicago
and New York/New Jersey provides a natural ceiling on systemic volatility and
may contribute to market stability during periods of extremely heavy trading
Wavefunctional approach to the bilayer \nu =1 system and a possibility for a double non-chiral pseudospin liquid
We systematically discuss candidate wave functions for the ground state of
the bilayer \nu = 1 as the distance between the layers is varied. Those that
describe increased intralayer correlations at finite distance show a departure
from the superflid description for smaller distances. They may support finite
energy meron excitations and a dissipative collective mode in the place of the
Goldstone mode of the ordered phase i.e. describe a vortex metal phase, or
imply even an incompressible, pseudospin liquid, behavior. Therefore they
describe possible outcomes of quantum disordering at finite distance between
the layers. The vortex metal phase may show up in experiments in the presence
of disorder at lower temperatures and explain the observed "imperfect
superfluidity", and the pseudospin liquid phase may be the cause of the
thermally activated (gapped) behavior of the longitudinal and Hall resistances
at higher temperatures in counterflow experiments.Comment: 10 pages, 4 figure
Effects of Nitrogen, Lime, and Boron on Candle Rape Grown in the Trapper Creek and Pt. MacKenzie Areas of Southcentral Alaska
When growers in the Susitna Valley and later in the Pt. MacKenzie area
of southcentral Alaska inquired as to the feasibility of growing rapeseed,
we decided to determine the crops suitability and performance by conducting
a field experiment. Bolton (1980) had attempted to predict the
feasibility of producing rapeseed in Alaska's interior, but no research had
been done in southcentral Alaska. We conducted one study from 1979
through 1981 on Rabideux silt loam (pH 5.1) near Trapper Creek and
another from 1982 through 1984 on Kashwitna silt loam (pH 5.4) on the
University of Alaska' s research tract in the Pt. MacKenzie area. The first
area had been cleared prior to 197 8. This area was rototilled and roots
removed in September 1978. The second area was on a tract cleared during
the winter of 1981. After clearing, rotary plowing was done twice
on the area. During the summer of 1981, roots were removed , and a field
cultivator was used twice to loosen and bring roots to the surface
Detection and Implications of a Time-reversal breaking state in underdoped Cuprates
We present general symmetry considerations on how a Time-reversal breaking
state may be detected by angle-resolved photoemission using circularly
polarized photons as has been proposed earlier. Results of recent experiments
utilizing the proposal in underdoped cuprates are analysed and found to be
consistent in their symmetry and magnitude with a theory of the Copper-Oxides.
These togather with evidence for a quantum critical point and marginal
Fermi-liquid properties near optimum doping suggest that a valid microscopic
theory of the phenomena in the cuprates has been found.Comment: A statement on detecting the Anyon state is added and some typos are
