Pickard, Kate E.R., letter, Camillus, [N.Y.], April 24, 1854, to "Uncle Peter" [Peter Still]
No full textKate Pickard acknowledges the receipt of Peter Still’s letter; consoles Still regarding news that he has received relating to the price for freeing his enslaved family; relays family news (e.g., of her sister Julia's marriage to Mr. LeGrand Marvin, a lawyer of Buffalo, N.Y.); regrets that his summer fundraising visit to her area the previous year was not as successful as it might have been, had it occurred in the winter; and counsels Still to trust in the Lord

A programming environment to control switching networks based on STC104 packet routing chip
No full textIntroduction This work is part of a test project for the third level trigger and on-line full event reconstruction for the HERA-B experiment[1]. The high event rate (10 MHz - corresponding to the bunch crossing rate) with multiple interactions per bunch crossing will produce more than 10 7 particles per second per square centimeter in the innermost detector region. The event rate is expected to be reduced by about five orders of magnitude by a three-level trigger system. The 1 AIHENP'96 SE-142 2 Corresponding author.

In the data acquisition scheme the event building is performed after the second level trigger decision. The events are then routed to the third level trigger, a

Pareto processes for threshold exceedances in spatial extremes
No full textWe review some recent development in the theory of spatial extremes related to Pareto Processes and modeling of threshold exceedances. We provide theoretical background, methodology for modeling, simulation and inference as well as an illustration to wave height modelling. This preprint is an author version of a chapter to appear in a collaborative book
LEVEL CROSSING IN MICROWAVE SPECTROSCOPY OF
No full textAuthor Institution: Laboratoire de Spectroscopie, Hertzienne, E.R.A. 150 Universit\'{e} de LilleNarrow level-crossing resonances have been observed by Stark tuning sublevels of the rotational line of at very low pressures. In our experiment, the level crossing width la about ten times smaller than the Doppler width of the absorption line. Saturation broadening of the level crossing dip has also been observed. Those level crossing signals have been obtained in zero Stark, field and also in a non-zero Stark field when an R.F, Stark field is superimposed. In the latter case, up to seven level crossing dips have been exhibited inside the Doppler width
Probing the transition from polynomial to exponential complexity in spin glasses via N-particle branching Brownian motions
No full textThe continuous random energy model (CREM) is a Gaussian process indexed by a binary tree of depth , introduced by Derrida and Spohn, then Bovier and Kurkova, as a toy model of a spin glass. Addario-Berry and the second author have established the existence of an algorithmic hardness threshold in the CREM: finding a state of energy lower than is possible in polynomial time if , with high probability. In this article, we are interested in the nature of the transition from polynomial to exponential complexity near the algorithmic hardness threshold. We do this by studying in detail the performance of a certain beam-search algorithm of beam width depending on -- we believe this algorithm to be natural and asymptotically optimal. The algorithm turns out to be essentially equivalent to the time-inhomogeneous version of the so-called -particle branching Brownian motion (-BBM), which has seen a lot of interest in the last two decades. Studying the performance of the algorithm then amounts to investigating the maximal displacement at time of the time-inhomogeneous -BBM. In doing so, we are able to quantify precisely the nature of the transition from polynomial to exponential complexity, proving that the transition happens when the log-complexity is of the order of . This result appears to be the first of its kind and we believe that this phenomenon should extend to other models.72 pages, 5 figure
A consistent dimensional analysis of gas–liquid mass transfer in an aerated stirred tank containing purely viscous fluids with shear-thinning properties
No full textThis paper deals with gas–liquid mass transfer in an aerated stirred tank containing Newtonian or shearthinning
fluids. The aim is to demonstrate that, for a given mixing system, an unique dimensionless correlation gathering all the mass transfer rates (150 kla measurements) can be obtained if and only if the variability of the rheological material parameters is correctly considered when implementing the theory of similarity. More particularly, it is clearly illustrated that a too gross simplification in the relevant list of the parameters characterizing the dependence of apparent viscosity with shear rates leads to pitfalls when building the PI-space set. This is then a striking example showing that a robust predictive correlation can be established when the non-constancy of fluid physical properties ceases to be neglected
STARK TUNED SATURATED ABSORPTION SPECTROSCOPY IN MICROWAVE DOMAIN
No full textAuthor Institution: Laboratoire de Spectroscopie Hertzienne, C.N.R.S., Universit\'{e}a de LilleA spectrometer has been built to work out Doppler-free saturated absorption experiments in the millimeter range (30-300 GHz): a plane-cylindrical resonator between Stark plates has been used. With that device, inverted Lamb-dips have been observed at 115 GHz with a width 25 times below the Doppler width. However, the essential feature of this apparatus is to allow the application of Stark fields typically 2500 V/cm leading to such specific uses as Stark tuned Lamb-dip, level-crossing and mode-crossing experiments. Typical examples will be given and other applications will be proposed
