PSF Sampling in Fluorescence Image Deconvolution
<p>All microscope imaging is largely affected by inherent resolution limitations because of out-of-focus light and diffraction effects. The traditional approach to restoring the image resolution is to use a deconvolution algorithm to “invert” the effect of convolving the volume with the point …

Comparison of PSF fitting methods for determining centroids of stars
… any of these models can be used for fitting a PSF to a star. However, if greater accuracy is needed more steps need to be taken in order to determine the best PSF fit.

Aktivitätsregulierung der humanen DNS-Topoisomerase I durch den RNS-Spleißfaktor PSF/p54nrb
… DNS-Topoisomerase I durch den Spleißfaktor PSF/p54nrb. Hierbei wurde aus A431-Zellextrakten ein Trimer aus Topoisomerase I und zwei weiteren Proteinen koisoliert. Nach Identifizierung der zwei weiteren Proteine als Spleißfaktor PSF und dessen kleinerem Homolog, dem nukleären Protein p54nrb, …

Combinatorial Regulation of Signal-Induced CD45 Exon Repression by hnRNP L and PSF
… as compared to resting cells. Additionally, PSF binds to the ESS1 complex in a signal-dependent manner and provides a significant increase in repressive activity. Further investigation shows these two mechanisms are largely independent but show some functional crosstalk, and while neither of …

Investigating spatial variation in the surface and atmosphere of Pluto through stellar occultations and PSF photometry
Stellar occultations provide a high-resolution view of a single chord through Pluto's atmosphere. This thesis presents three projects related to stellar occultation observations of Pluto. The first project concerns the ground testing of the High-speed Imaging Photometer for Occultations (HIPO), a …

Investigation of the Polyprimidine Tract-Binding Protein-Associated Splicing Factor (PSF) Domains Required for the Hepatitis Delta Virus (HDV) Replication
… protein-associated splicing factor (PSF), an HDV interacting protein, was found to interact with the carboxy terminal domain (CTD) of RNA polymerase II (RNAPII), and to facilitate the interaction of RNA transcripts with the CTD of RNAPII. Both PSF and RNAPII were found to interact …

The influence of biosynthesis zinc oxide nanoparticles by using fruit extracts of ananas comosus towards the performance of PSF/ZNO membrane
… properties and performance polysulfone (PSf) mixed matrix membrane. The biosynthesis ZnO, (ZnO (P)) nanoparticles powder was successfully synthesized by using fruit extracts of Ananas Comosus. The characterization and performance of the ZnO (P) were conducted in this study and compared …

Weighted running: Effect on impact and oxygen consumption
… weight at their preferred stride frequency (PSF) and at +/-10% PSF. Oxygen consumption (VO2) and PSF were recorded. VO2 and PSF were greater during nonweighted compared to weighted running (p < 0.05). During weighted running, VO2 was greater when running at the -10% PSF than the PSF, but not …

Studies of vascular function in patients with heart failure and either preserved or reduced left ventricular systolic function
… preserved left ventricular systolic function (HF-PSF). Invasive studies utilising cardiac catheterisation have demonstrated that patients with HF-PSF have abnormalities of left ventricular (LV) relaxation and filling, or LV diastolic dysfunction. As a result, it has been proposed that LV diastolic …

Long exposure point spread function estimation from solar adaptive optics loop data
… a good estimate of the point spread function (PSF) is required. PSF estimates are impossible to measure directly during solar observations due to the lack of point sources in the field-of-view. Moreover, the highly variable day-time seeing conditions require the estimated PSF to be simultaneous …

Plant-Soil Feedback and Perennial Forage Systems
Plant-soil feedback (PSF) is the process by which plants influence the survival and growth of other plants through effects on the soil and its biota. Understanding how PSF and management practices interact to influence native species persistence is critical for sustainable perennial forage systems. …

The effect of flower-like tatania towards characteristics and performance of polysulfone mixed matrix membrane
For ages, the polymeric membrane such as PSf is widely used in liquid separation for various application as the polymer itself offer versatile and attractive properties. However, due to strong hydrophobic nature of PSf property that create serious fouling problem to most of the separation process, …

The study is placed in the context of change, externally in the regulation and competitive environment of PSFs, and internally in terms of the commercialisation of the PSF and the adoption of financial …

Point Spread Function Reconstruction for the Adaptive Optics System ALFA and its Application to Photometry
… nature of the system point spread function (PSF). Generally, the PSF information cannot be taken from the images due to anisoplanacy and/or overexposure of the guide star. It is therefore highly desirable to obtain an independent estimate of the PSF at each position in the field of view. This …
