The ongoing search for signs of life on Mars relies in part on terrestrial analogs – places on Earth closely resembling the past or current geology and climate of the red planet that can be readily ex...
Changes in the mutual orientation of tRNA and 23S rRNA at the peptidyl transferase center of the ribosome detected by crosslinking of a photoreactive transition-state analog
Amino acids dynamic interaction ribosomes peptide bonds peptidyl transferase ribosomes
2014/12/11
Dynamic interactions between the amino acid acceptor end of tRNA and the ribosome underlie the synthesis of successive peptide bonds at the peptidyl transferase center (PTC) of the 50S ribosomal subun...

2014/12/9
This project developed an analog correlating spectrometer intended for use in millimeter Astronomy. It is based in part on the Wideband Analog Spectrometers (WASP and WASP-II) built by Harris, et al (...
The Regulation of Chemerin and CMKLR1 Genes Expression by TNF-α, Adiponectin, and Chemerin Analog in Bovine Differentiated Adipocytes
Bovine Adipocyte Chemerin CMKLR1 TNF-α Adiponectin
2016/5/10
Adipokines, adipocyte-derived protein, have important roles in various kinds of physiology including energy homeostasis. Chemerin, one of adipocyte-derived adipokines, is highly expressed in different...
Lower Bounds on the Performance of Analog to Digital Converters
Lower Bounds Performance Analog Digital Converters
2012/4/16
This paper deals with the task of finding certified lower bounds for the performance of Analog to Digital Converters (ADCs). A general ADC is modeled as a causal, discrete-time dynamical system with o...
Maximum-likelihood reconstruction of photon returns from simultaneous analog and photon-counting lidar measurements
Maximum-likelihood reconstruction photon returns simultaneous analog photon-counting lidar
2011/10/18
We present a novel method for combining the analog and photon-counting measurements of lidar transient recorders into reconstructed photon returns. The method takes into account the statistical proper...
A global analog of the Springer resolution for $SL_2$
the Springer resolution global analog Algebraic Geometry
2011/9/20
Abstract: The global nilpotent cone N is a singular stack associated to the choice of an algebraic group G, a smooth projective curve X, and a line bundle L on X, which is of fundamental importance to...
The Discrete Analog of the Malgrange-Ehrenpreis Theorem
the Malgrange-Ehrenpreis Theorem The Discrete Analog Combinatorics
2011/9/19
Abstract: One of the landmarks of the modern theory of partial differential equations is the Malgrange- Ehrenpreis theorem that states that every non-zero linear partial differential operator with con...

Abstract: We present a novel method for combining the analog and photon-counting measurements of lidar transient recorders into reconstructed photon returns. The method takes into account the statisti...
Evolution of Photonic Time Stretch: From Analog to Digital Conversion to Blood Screening
Photonic Digital Conversion Blood Screening
2011/9/6
We show how the ability to slow down, amplify, and capture fast transient events can produce high-throughput real-time instruments ranging from digitizers to imaging flow cytometers for detection of r...
Some years ago I happened to be listening to a lecture given by Gregory Chaitin on what he called as 攄igital philosophy.?[1] In the following night,just before falling asleep, I was lying on my bed wo...
Function Theory on a q-Analog of Complex Hyperbolic Space
Function Theory q-Analog of Complex Hyperbolic Space
2010/12/15
This work deals with function theory on quantum complex hyperbolic spaces. The prin-cipal notions are expounded. We obtain explicit formulas for invariant integrals on ‘finite’
functions on a quantum...
Construction and Commissioning of the CALICE Analog Hadron Calorimeter Prototype
nuclear interaction hadron calorimeter
2010/3/16
An analog hadron calorimeter (AHCAL) prototype of 5.3 nuclear interaction lengths thickness has been constructed by members of the CALICE Collaboration. The AHCAL prototype consists of a 38-layer sand...
We present a sub-Nyquist analog-to-digital converter of wideband inputs. Our circuit realizes the recently proposed modulated wideband converter, which is a flexible platform for sampling signals acco...
