Reliable adaptive modulation and interference mitigation for mobile radio slow frequency hopping channels
Lei, M., Due-Hallen, A., & Hallen, H. (2008, March). IEEE TRANSACTIONS ON COMMUNICATIONS, Vol. 56, pp. 352–355.
author keywords: slow frequency hopping; channel state information; long range prediction; adaptive transmission; partial-band interference; diversity
TL;DR:
The long range fading prediction algorithm for Slow Frequency Hopping systems is proposed and demonstrated to enable combined adaptive modulation and adaptive frequency diversity to mitigate the effects of fading and partial-band interference.

1999 journal article
Relation between non-uniform hemodynamics and sites of altered permeability and lesion growth at the rabbit aorto-celiac junction
ATHEROSCLEROSIS, 143(1), 27–40.
author keywords: computational simulation; aorto-celiac junction; hemodynamic parameters; enhanced wall permeability; WBC uptake; atherosclerotic lesion growth
MeSH headings : Animals; Aorta, Abdominal / pathology; Aorta, Abdominal / physiopathology; Aorta, Thoracic / physiopathology; Arteriosclerosis / pathology; Arteriosclerosis / physiopathology; Blood Flow Velocity; Capillary Permeability; Celiac Artery / pathology; Celiac Artery / physiopathology; Computer Simulation; Hemorheology; Leukocytes / physiology; Models, Cardiovascular; Rabbits; Stress, Mechanical
TL;DR:
This study presents a rationale for further quantitative correlative studies in the rabbit model based on additional histological data sets and shows a statistically significant correlation between the wall shear stress (WSS), the oscillatory shear index (OSI), and the spatial wallShear stress gradient (W SSG).

Computational design of a bypass graft that minimizes wall shear stress gradients in the region of the distal anastomosis
JOURNAL OF VASCULAR SURGERY, 25(4), 637–646.
MeSH headings : Algorithms; Anastomosis, Surgical / adverse effects; Anastomosis, Surgical / methods; Arterial Occlusive Diseases / prevention & control; Arterial Occlusive Diseases / surgery; Arteries / pathology; Arteries / surgery; Arteriosclerosis / etiology; Computer Simulation; Constriction, Pathologic / prevention & control; Constriction, Pathologic / surgery; Hemodynamics; Hemorheology / classification; Humans; Hyperplasia; Models, Cardiovascular; Physical Exertion / physiology; Recurrence; Regional Blood Flow; Rest / physiology; Stress, Mechanical; Thrombosis / prevention & control; Tunica Intima / pathology
TL;DR:
It is demonstrated that it is possible to design a terminal graft geometry for an end-to-side anastomosis that significantly reduces wall shear stress gradients, and this results may point to the design of optimal bypass graft geometries.

1997 article
Hemodynamic simulations and computer aided designs of graft-artery junctions
Lei, M., Kleinstreuer, C., & Archie, J. P. (1997, August). JOURNAL OF BIOMECHANICAL ENGINEERING-TRANSACTIONS OF THE ASME, Vol. 119, pp. 343–348.
MeSH headings : Algorithms; Anastomosis, Surgical / adverse effects; Animals; Arteries / physiopathology; Blood Flow Velocity; Blood Vessel Prosthesis / adverse effects; Computer Simulation; Computer-Aided Design; Constriction, Pathologic / etiology; Constriction, Pathologic / physiopathology; Femoral Artery / physiology; Femoral Artery / surgery; Hemodynamics / physiology; Humans; Models, Cardiovascular; Recurrence; Stress, Mechanical; Vascular Patency
TL;DR:
The hypothesis is that nonuniform hemodynamics, represented by large sustained wall shear stress gradients, trigger abnormal biological processes leading to rapid restenosis and hence early graft failure, and this problem may be significantly mitigated by designing graft-artery bypass configurations for which the wallShear stress gradient is approximately zero and hence nearly uniform hemodynamics are achieved.
