Ordered multi-path propagation for vessel centerline extraction.

Phys Med Biol 2021 Jul 19;66(15). Epub 2021 Jul 19.

Laboratory of Beijing Engineering Research Center of Mixed Reality and Advanced Display, School of Optics and Photonics, Beijing Institute of Technology, Beijing 100081, People's Republic of China.

Vessel centerline extraction from x-ray angiography images is essential for vessel structure analysis in the diagnosis of coronary artery disease. However, complete and continuous centerline extraction remains a challenging task due to image noise, poor contrast, and complexity of vessel structure. Thus, an iterative multi-path search framework for automatic vessel centerline extraction is proposed. Read More

To be alive when dying: moral catharsis and hope in patients with limited life prognosis.

Oscar Vergara

Med Health Care Philos 2021 Jun 3. Epub 2021 Jun 3.

Faculty of Law, Department of Private Law, Universidade da Coruña, 15071, A Coruña, Galicia, Spain.

The Stoics considered that in order to die well, one must previously have lived (well) and not merely existed, an assertion which will not be contested in this paper. The question raised here is whether an individual whose life expectancy is jeopardized by serious illness or whose life has not been lived to the 'full' for whatever reason should have to abandon all hope or, alternately, whether that life could still somehow be saved (in an ethical sense). One clear obstacle to achieving this stems from (bad) moral character, given that moral character is an element which conditions an individual's moral behaviour, as pointed out by Beauchamp and Childress and particularly Pellegrino and Thomasma.

Do visible semantic primes preactivate lexical representations?

J Exp Psychol Learn Mem Cogn 2020 Aug 5;46(8):1533-1569. Epub 2020 Mar 5.

Department of Psychology, University of Western Ontario.

Considerable research effort has been devoted to investigating semantic priming effects, particularly, the locus of those effects. Semantically related primes might activate their target's lexical representation (through automatic spreading activation at short stimulus onset asynchronies (SOAs), or through generation of words expected to follow the prime at longer SOAs). Alternately, semantically related primes might aid responding after target identification (i. Read More

The Novel Strategy for Increasing the Efficiency and Yield of the Bipolar Membrane Electrodialysis by the Double Conjugate Salts Stress.

Polymers (Basel) 2020 Feb 5;12(2). Epub 2020 Feb 5.

College of Environment and Safety Engineering, Qingdao University of Science and Technology, Qingdao 266042, China.

To improve sulfuric acid recovery from sodium sulfate wastewater, a lab-scale bipolar membrane electrodialysis (BMED) process was used for the treatment of simulated sodium sulfate wastewater. In order to increase the concentration of sulfuric acid (HSO) generated during the process, a certain concentration of ammonium sulfate solution was added into the feed compartment. To study the influencing factors of sulfuric acid yield, we prepared different concentrations of ammonium sulfate solution, different feed solution volumes, and different membrane configurations in this experiment.

Materials (Basel) 2019 Dec 6;12(24). Epub 2019 Dec 6.

State Key Laboratory of Advanced Welding and Joining, Harbin Institute of Technology, Harbin 150001, China.

Tungsten inert gas (TIG) arc welding of 2219 aluminum alloy was assisted with a trailing periodic ultrasonic vibration, which was output from a trailing roller behind the welding torch. It was found that the weld appearance was periodically convex due to the periodic input of ultrasonic vibration. With the addition of ultrasonic vibration, the columnar grains in the weld zone transformed to equiaxed grains, so along the longitudinal direction, the equiaxed grains and the columnar grains were alternately distributed due to the periodic ultrasonic vibration.

IEEE Trans Neural Netw Learn Syst 2020 Feb 19;31(2):559-573. Epub 2019 Apr 19.

Convolutional sparse coding (CSC) is a useful tool in many image and audio applications. Maximizing the performance of CSC requires that the dictionary used to store the features of signals can be learned from real data. The so-called convolutional dictionary learning (CDL) problem is formulated within a nonconvex, nonsmooth optimization framework. Read More

McSART: an iterative model-based, motion-compensated SART algorithm for CBCT reconstruction.

Phys Med Biol 2019 04 26;64(9):095013. Epub 2019 Apr 26.

Department of Radiation Oncology, David Geffen School of Medicine, UCLA, Los Angeles, CA, United States of America.

4D cone beam computed tomography (CBCT) images of the thorax and abdomen can have reduced quality due to the limited number of projections per respiratory bin used in gated image reconstruction. In this work, we present a new algorithm to reconstruct high quality CBCT images by simultaneously reconstructing images and generating an associated respiratory motion model. This is done by updating model parameters to compensate for motion during the iterative image reconstruction process. Read More

Magn Reson Med 2018 11 6;80(5):2188-2201. Epub 2018 Apr 6.

School of Electrical and Electronic Engineering, Yonsei University, Seoul, Korea.

Purpose: To demonstrate accurate MR image reconstruction from undersampled k-space data using cross-domain convolutional neural networks (CNNs) METHODS: Cross-domain CNNs consist of 3 components: (1) a deep CNN operating on the k-space (KCNN), (2) a deep CNN operating on an image domain (ICNN), and (3) an interleaved data consistency operations.
