Changes on Confocal Scanning Laser Ophthalmoscopy with the Heidelberg Retinal Tomography after a Cardiac Catheterism in a Patient with Progressive Glaucoma
摘要： Purpose: We present a case of a patient with progressive open angle glaucoma who presented changes suggestive of improvement in the Heidelberg retinal tomography 3 (HRT3) analysis after a cardiac catheterization. Observation: A 69-year-old woman presented with progressive open angle glaucoma despite maximum tolerable antiglaucomatous topical treatment. A filtering surgery (trabeculectomy) was performed and successfully achieved intraocular pressure (IOP) levels of 10 mm Hg on average. Despite this, changes were evidenced in the HRT3 protocols (trend analysis and topographic change analysis) suggesting marked progression. Brimonidine 0.2% twice a day was initiated, and a cardiovascular examination was requested. A cardiac catheterism was performed in the following weeks, and afterward, all structural parameters improved until the last control. Medication was not discontinued, and no signs of apparent progression on the HRT3 parameters have been evidenced up until the time of writing this case report. Conclusions and Importance: There was a marked improvement in the HRT3 parameters (trend and topographic change analysis), suggesting that the progression stopped after a cardiac catheterism in a patient with progressive glaucoma despite having the IOP controlled. To our knowledge, this is the first case of a patient with progressive glaucoma that was medically and surgically managed, and despite achieving low IOP levels, the progression detected by the HRT3 analysis could not be stopped until a cardiac catheterization was performed.

Lanczos-based equation-of-motion coupled-cluster singles-and-doubles approach to the total photoionization cross section of valence excited states
摘要： Excitation energies and oscillator strengths of the first two electronically excited states of helium, water, sulfur dioxide, molecular nitrogen, and carbon monoxide were obtained from an asymmetric-Lanczos-based formulation of the equation-of-motion coupled cluster singles and doubles approach. The total photoionization cross sections were generated by two different methodologies: an analytic continuation procedure based on the Padé approximants and the Stieltjes imaging technique. The results are compared with theoretical photoionization cross sections from algebraic diagrammatic construction [ADC(2)] and ADC(2)-x calculations [M. Ruberti et al., J. Chem. Phys. 140, 184107 (2014)] and with available experimental data.

[IEEE 2018 IEEE International Conference on Computational Photography (ICCP) - Pittsburgh, PA (2018.5.4-2018.5.6)] 2018 IEEE International Conference on Computational Photography (ICCP) - ADP: Automatic differentiation ptychography
摘要： Ptychography is an imaging technique which aims to recover the complex-valued exit wavefront of an object from a set of its diffraction pattern magnitudes. Ptychography is one of the most popular techniques for sub-30 nanometer imaging as it does not suffer from the limitations of typical lens based imaging techniques. The object can be reconstructed from the captured diffraction patterns using iterative phase retrieval algorithms. Over time many algorithms have been proposed for iterative reconstruction of the object based on manually derived update rules. In this paper, we adapt automatic differentiation framework to solve practical and complex ptychographic phase retrieval problems and demonstrate its advantages in terms of speed, accuracy, adaptability and generalizability across different scanning techniques.
