Efficient coherent diffractive imaging for sparsely varying objects.

Optics express

Shechtman Y, Eldar YC, Cohen O, Segev M.
PMID: 23482202
Opt Express. 2013 Mar 11;21(5):6327-38. doi: 10.1364/OE.21.006327.

We demonstrate an efficient phase-retrieval method, allowing the recovery of features of dynamic objects that are sparsely varying--i.e. when the difference between two consecutive frames is small. The method uses redundancy in information between similar consecutive frames to recover...

PlenoPatch: Patch-Based Plenoptic Image Manipulation.

IEEE transactions on visualization and computer graphics

Zhang FL, Wang J, Shechtman E, Zhou ZY, Shi JX, Hu SM.
PMID: 26915124
IEEE Trans Vis Comput Graph. 2017 May;23(5):1561-1573. doi: 10.1109/TVCG.2016.2532329. Epub 2016 Feb 19.

Patch-based image synthesis methods have been successfully applied for various editing tasks on still images, videos and stereo pairs. In this work we extend patch-based synthesis to plenoptic images captured by consumer-level lenselet-based devices for interactive, efficient light field...

Tilted Light Sheet Microscopy with 3D Point Spread Functions for Single-Molecule Super-Resolution Imaging in Mammalian Cells.

Proceedings of SPIE--the International Society for Optical Engineering

Gustavsson AK, Petrov PN, Lee MY, Shechtman Y, Moerner WE.
PMID: 29681676
Proc SPIE Int Soc Opt Eng. 2018 Feb;10500. doi: 10.1117/12.2288443.

To obtain a complete picture of subcellular nanostructures, cells must be imaged with high resolution in all three dimensions (3D). Here, we present tilted light sheet microscopy with 3D point spread functions (TILT3D), an imaging platform that combines a...

Incidence and risk factors of pneumothorax following pre-procedural ultrasound-guided thoracentesis.

Journal of thoracic disease

Shechtman L, Shrem M, Kleinbaum Y, Bornstein G, Gilad L, Grossman C.
PMID: 32274162
J Thorac Dis. 2020 Mar;12(3):942-948. doi: 10.21037/jtd.2019.12.39.

BACKGROUND: Data regarding the incidence and risk factors of pneumothorax following pre-procedural ultrasound (US)-guided thoracentesis is scarce. We aimed to evaluate the incidence and risk factors of pneumothorax following pre-procedural US-guided thoracentesis in a tertiary medical center.METHODS: Retrospective analysis...

Fundamental Precision Bounds for Three-Dimensional Optical Localization Microscopy with Poisson Statistics.

Physical review letters

Backlund MP, Shechtman Y, Walsworth RL.
PMID: 30085695
Phys Rev Lett. 2018 Jul 13;121(2):023904. doi: 10.1103/PhysRevLett.121.023904.

Point source localization is a problem of persistent interest in optical imaging. In particular, a number of widely used biological microscopy techniques rely on precise three-dimensional localization of single fluorophores. As emitter depth localization is more challenging than lateral...

Improving techniques for diagnostics of laser pulses by compact representations.

Optics express

Sidorenko P, Dikopoltsev A, Zahavy T, Lahav O, Gazit S, Shechtman Y, Szameit A, Tannor DJ, Eldar YC, Segev M, Cohen O.
PMID: 31052703
Opt Express. 2019 Mar 18;27(6):8920-8934. doi: 10.1364/OE.27.008920.

We propose and demonstrate, numerically and experimentally, use of sparsity as prior information for extending the capabilities and performance of techniques and devices for laser pulse diagnostics. We apply the concept of sparsity in three different applications. First, we...

Efficacy of the mRNA-Based BNT162b2 COVID-19 Vaccine in Patients with Solid Malignancies Treated with Anti-Neoplastic Drugs.

Cancers

Agbarya A, Sarel I, Ziv-Baran T, Agranat S, Schwartz O, Shai A, Nordheimer S, Fenig S, Shechtman Y, Kozlener E, Taha T, Nasrallah H, Parikh R, Elkoshi N, Levy C, Khoury R, Brenner R.
PMID: 34439346
Cancers (Basel). 2021 Aug 20;13(16). doi: 10.3390/cancers13164191.

The BNT162b2 vaccine was shown to be highly effective in reducing the risk of COVID-19 infection in healthy individuals and patients with chronic disease. However, there are little data regarding its efficacy in patients treated for cancer. We analyzed...

Is the coefficient of variation a valid measure for detecting sincerity of effort of grip strength?.

Work (Reading, Mass.)

Shechtman O.
PMID: 12441559
Work. 1999;13(2):163-169.

The wide use of the coefficient of variation in detecting sincerity of effort is puzzling since existing research findings regarding its effectiveness are contradictory. The lack of empirical support in the literature raises the question of whether or not...

Environmental modulation of both locomotor response and locomotor sensitization to the dopamine agonist quinpirole.

Behavioural pharmacology

Einat H, Szechtman H.
PMID: 11224208
Behav Pharmacol. 1993;4(4):399-403.

The study tested whether differences in locomotor activation during chronic treatment result in differential behavioral sensitization induced by the D2/D3 dopamine agonist quinpirole. One group of rats received repeated injections of quinpirole in their home cage and another group...
