FLASH LiDAR SINGLE PHOTON IMAGING OVER 50 KM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
In order to demonstrate the feasibility of single-photon imaging of flash lidar in the permanent shadow area of the moon, a set of space-based single-photon imaging system is designed, including the lidar based on VCSEL array, the optical emitting system

Interval analysis of repetitive complexes in SSPE: 45 [PDF]

open access: yesPediatric Research, 1980
The time intervals between biologic phenomena(f.e. between R-waves of ECG or respiration excursions) are not always very constant. Nevertheless such events are called "periodic".In fact the train of intervals depends on periodic and superimposed random factors(=noise).A significant task of an analysis of biologic rhythms is to separate the really ...

The Relentless Attempt to Perfect the 2-Stent Technique∗ [PDF]

open access: yes, 2015
Individual data points for one repetition maximum before (a) and after the intervention period (b) and for average power at 40% of one repetition maximum before (c) and after the intervention period (d) for the upper-body sprint-interval training group ...

Shortening of subjective tone intervals followed by repetitive tone stimuli [PDF]

open access: yesAttention, Perception, & Psychophysics, 2010
Accumulated evidence shows that a subjective time interval is lengthened by preceding or concurrent presentation of flickers or repetitive tone stimuli that have been hypothesized to increase the frequency of pulse generation by a brain pacemaker. In the present study, we presented a series of repetitive tone stimuli after an interval that started and ...

Time Dependent Clustering Analysis of the Second BATSE Gamma-Ray Burst Catalog [PDF]

open access: yes, 1994
A time dependent two-point correlation-function analysis of the BATSE 2B catalog finds no evidence of burst repetition. As part of this analysis, we discuss the effects of sky exposure on the observability of burst repetition and present the equation ...

Dynamic modal analysis of monolithic mode-locked semiconductor lasers [PDF]

open access: yes, 2003
We analyze the advantages and applicability limits of the mode-coupling approach to active, passive, hybrid, and harmonic mode-locking in diode lasers. A simple, computationally efficient numerical model is proposed and applied to several traditional and

Attention modulates the processing of emotional expression triggered by foveal faces [PDF]

open access: yes, 2006
To investigate whether the processing of emotional expression for faces presented within foveal vision is modulated by spatial attention, event-related potentials (ERPs) were recorded in response to stimulus arrays containing one fearful or neutral face ...

Streaming Codes for Channels with Burst and Isolated Erasures [PDF]

open access: yes, 2012
We study low-delay error correction codes for streaming recovery over a class of packet-erasure channels that introduce both burst-erasures and isolated erasures. We propose a simple, yet effective class of codes whose parameters can be tuned to obtain a

Quentin Tarantino : du cinéma d’exploitation au cinéma

open access: yesTransatlantica, 2016
It is fairly obvious that Tarantino has contributed to making exploitation cinema, if not universally popular, at least acceptable to a wider audience than its initial niche fans.

Redundant laboratory testing on referral from general practice to the outpatient clinic: a post-hoc analysis

open access: yesBJGP Open, 2022
Background: Inappropriately repeated laboratory testing is a commonly occurring problem. However, this has not been studied extensively in the outpatient clinic after referral by GPs.
