Multi-pass microscopy

Nature Communications, 2016
Low-damage and high-precision imaging can be achieved by passing the same probe photons through the specimen more than once, and this has been previously achieved in double-pass transmission microscopy.

Superlinear Lower Bounds for Multipass Graph Processing [PDF]

2013 IEEE Conference on Computational Complexity, 2013
We prove $n^{1+Ω(1/p)}/p^{O(1)}$ lower bounds for the space complexity of $p$-pass streaming algorithms solving the following problems on $n$-vertex graphs: * testing if an undirected graph has a perfect matching (this implies lower bounds for computing a maximum matching or even just the maximum matching size), * testing if two specific vertices are ...

A Dynamic 3D Human Liver Sinusoid Model for Mechanistic Interrogation of Fontan‐Associated Liver Disease

Advanced Science, Volume 13, Issue 30, 28 May 2026.
This study presents a perfusable 3D bioengineered liver sinusoid platform that integrates biofabrication, 3D cell culture, controlled hemodynamics, and multiparametric characterization to model Fontan‐associated liver disease. By decoupling pressure and hypoxia effects, the system reveals early mechanobiological and profibrotic responses under ...

Multipass Active Contours for an Adaptive Contour Map [PDF]

Sensors, 2013
Isocontour mapping is efficient for extracting meaningful information from a biomedical image in a topographic analysis. Isocontour extraction from real world medical images is difficult due to noise and other factors. As such, adaptive selection of contour generation parameters is needed.

Multiresponse Tribological Ranking Alternatives of Al–Cu Alloys via an Integrated Taguchi Experimental Design, AHP Weighting, and WASPAS Decision Framework

Engineering Reports, Volume 8, Issue 5, May 2026.
To optimize aluminium–copper alloy compositions and tribological parameters for improved wear performance using an integrated hybrid MCDM approach. The Al–Cu alloy compositions were fabricated through die casting. Their tribological performance was evaluated and optimized using a hybrid Taguchi–AHP–WASPAS methodology under varying loads, sliding speeds,

Improved control for media-scale multipass simulations

, 2022
S.692-698Current media-scale multipass simulations in GeoDict/FilterDict work with a fixed amount of test dust per particle batch. This does not account properly for the transition from depth filtration to cake filtration.

Modelocked Thin-Disk Laser Oscillator with 550 W of Average Output Power [PDF]

EPJ Web of Conferences
We present an ultrafast thin-disk laser oscillator providing a record power of 550 W with 100-µJ, 852-fs pulses at a repetition rate of 5.5 MHz. This is enabled by a six-pass replicating-cavity multipass scheme and ion-implanted sapphire-bonded SESAMs.

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...

Numerical modelling of temperature distribution during multipass welding of plates

, 2000
Welding is a reliable, cost effective, and efficient metal joining process. Manual metal arc welding (MMAW) is a widely used welding process in industry and multipass welding is very frequently used in the MMAW process.
