Nonlinear ptychographic coherent diffractive imaging

Ptychographic Coherent diffractive imaging (PCDI) is a significant advance in imaging allowing the measurement of the full electric field at a sample without use of any imaging optics. So far it has been confined solely to imaging of linear optical responses. In this paper we show that because of the coherence-preserving nature of nonlinear optical interactions, PCDI can be generalised to nonlinear optical imaging. We demonstrate second harmonic generation PCDI, directly revealing phase information about the nonlinear coefficients, and showing the general applicability of PCDI to nonlinear interactions

This research was carried out in the village of Polewali, Bambalamotu subdistrict, Regency of North Mamuju, West Sulawesi province in December 2015. The respondent\u27s determination is done by a simple random sampling method, determining in the number of samples is done using the formula of slovin, respondents were taken in this research as much as 31 KK of 74 KK population numbers. This research is carried out by surveys, data collected in the form of primary and secondary data. The results of the analysis showed that the income earned of copra entrepreneur in the village of Polewali is Rp. 10.561.780/four months and it is when averaged is Rp. 2.640.445/month. The results of the analysis of contribution rate of necessities of worthy life (MOE) showed that the necessities of worthy life which have met the criteria based on Sinukaban is of 1.04 percent, the WORLD BANK\u27S US $1 is 1,58$ 2 is 0.79%, and on the basis of 0.33% KHl and UMP West Sulawesi province is 0.37% so the revenue contribution by employers in the village of Polewali copra is not fully met the criteria of the necessities of worthy life of 1%

An autocorrelator-interferometer used to determine the pulse width of a pulsed laser used in two-photon endoscopy

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, June 2005."May 2005."Includes bibliographical references (leaf 9).An autocorrelator-inferometer was designed to correctly assess the pulse width of pulse laser used in two photon endoscopy. The path length of the light was altered using a retro-reflecting corner cube attached to a 6880 galvanometer optical scanner controlled by a 671 series micro-max controller (both products by Cambridge Technologies Inc.) The scanner was selected due to its ability to traverse very small rotations with a constant angular velocity, thereby reducing any non-linearities (with respect to time) in the autocorrelation. The projected results of this autocorrelator suggest it can be used to analyze electromagnetic waves with pulses on the order of a couple picoseconds, however, due to an imbalance of the scanner's shaft, the device was broken before any tests could be performed. A preliminary analysis suggests that a circular shaft attachment could be used to prevent this problem in the future.by Nicholas A. Baksh.S.B

Full characterisation of a focussed extreme ultraviolet beam using a non-redundant array of apertures

This paper presents a novel technique for characterising wavefront curvature and M2, by utilising a non-redundant array (NRA) of apertures to define the plane of investigation through an experimental extreme ultraviolet (EUV) focus. Appropriately sampled, far-field EUV scattering from this NRA is captured on a CCD as the NRA is scanned along the beam axis through the focus. By taking the inverse Fourier transform (IFT), it is possible obtain the spatial autocorrelation functions, via the Wiener-Khinchin theorem, of the exit wave field. By observing the position of the first-order peaks in the autocorrelation as a function of grid translation, both the real and imaginary parts of the complex beam parameter can be determined and the M2 calculated, yielding full characterisation of the embedded Gaussian. Since the periodicity of the grid is known, the planar pixel resolution can be calculated, also allowing the translations movement to be confirmed due to the change in angular acceptance of the fixed CCD. This makes the technique self-calibrating. A high impact, easy to use, cross field technique for full profiling of the embedded Gaussian of probe beams using a non-redundant array of apertures is presented. The technique is experimentally verified in the highly absorbing EUV spectral regime, and is expected to play a significant role in other regimes, where experimental issues prevent the use of existing techniques

Improved methods for the analysis of circadian rhythms in correlated gene expression data

Circadian clocks regulate biological behaviours, such as sleeping and waking times, that recur naturally on an approximately 24-hour cycle. These clocks tend to be influenced by a variety of external factors, sometimes to the extent that it can have an impact on health. As an example in pharmacology, the effects of chemicals on the circadian rhythm in patients can be key in clarifying the relationship of drug efficacy and toxicity with dosing times. While pre-clinical experiments conducted to elucidate these effects may produce correlated data measured over time, such as gene expression profiles, existing methods for fitting parametric nonlinear regression models are however inadequate and can lead to unreliable, inconsistent parameter estimates and invalid inference. A de-trending method is widely used as a pre-processing step to address the non-stationary problem in the data before fitting models based on the assumption of independence. However, as it is unclear that this approach properly accounts for the correlation structure, alternative methods that specifically model the correlation in the data based on conditional least squares and a two-stage estimation procedure are proposed and evaluated. A simulation study covering a wide range of scenarios and models show that the proposed methods more efficient and robust to model mis-specification than de-trending and, furthermore, they lead to reduced bias in estimation of the circadian period and more reliable confidence intervals
