Design and Simulation of the Spiral Micromixer with Chaotic Advection [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
In recent years, the microfluidics technique has screwed up rising attention and be in progress a fascinating topic. Species mixing is a compelling part of any microfluidic system that abides by the major challenge.

Dynamic Enhanced Computed Tomographic Findings of a Perirenal Capillary Hemangioma

open access: yes대한영상의학회지, 2016
Hemangiomas are benign mesenchymal neoplasms that rarely occur in the kidney and perirenal space. Perirenal hemangiomas can mimic the appearance of exophytic renal cell carcinoma or various retroperitoneal tumors. We report a case of perirenal hemangioma

Six New Galactic Orbits of Globular Clusters in a Milky-Way-Like Galaxy [PDF]

open access: yes, 2007
Absolute proper motions for six new globular clusters have recently been determined. This motivated us to obtain the Galactic orbits of these six clusters both in an axisymmetric Galactic potential and in a barred potential, such as the one of our Galaxy.

Spiral computed tomography of pulmonary embolism [PDF]

open access: yesEuropean Respiratory Journal, 2002
Within the last several years, spiral computed tomography angiography (SCTA) of the pulmonary arteries has emerged as a noninvasive angiographic modality for the evaluation of patients with suspected pulmonary embolism (PE). SCTA is based on continuous computed tomography (CT) data acquisition during patient transport through the rotating X‐ray tube ...

Artificial intelligence can help individualize Wilms tumor treatment by predicting tumor response to preoperative chemotherapy [PDF]

open access: yesInvestigative and Clinical Urology
"Purpose: To create a computer-aided prediction (CAP) system to predict Wilms tumor (WT) responsiveness to preoperative chemotherapy (PC) using pre-therapy contrast-enhanced computed tomography (CECT). Materials and Methods: A single-center database was

Determining the opacity of urinary stone using only the Computed Tomography imaging, Is KUB still needed?

open access: yesMen's Health Journal, 2021
Introduction: Defining the opacity of urinary stones by Kidney -Ureter-Bladder (KUB) imaging in the selection of treatment modality is considered necessary by many urologists. This imposes more radiation to patients and additional health costs.

Bosonic Mean Field Theory of the Spiral Phases of Heisenberg Antiferromagnets on a Chain [PDF]

open access: yes, 1993
We develop a novel bosonic mean field theory to describe the spiral phases of a Heisenberg antiferromagnet on a one-dimensional chain, in terms of three bosons at each site.

Anastomosing Hemangioma Involving the Para-Aortic Region: A Case Report

open access: yes대한영상의학회지, 2017
Anastomosing hemangioma (AH) is a rare and benign vascular neoplasm that is regarded as a morphological variant of capillary hemangioma. AH has been encountered primarily in the kidney.

Radiologic Diagnosis of Gastrointestinal Bleeding

open access: yesJournal of the Korean Society of Radiology, 2023
Gastrointestinal (GI) bleeding is not a single disease but a symptom and clinical manifestation of a broad spectrum of conditions in the GI tract. According to its clinical presentation, GI bleeding can be classified into overt, occult, and obscure ...

A New Model for the Spiral Structure of the Galaxy. Superposition of 2+4-armed patterns

open access: yes, 2000
We investigate the possibility of describing the spiral pattern of the Milky Way in terms of a model of superposition 2- and 4-armed wave harmonics (the simplest description, besides pure modes).
