The publication of the first article in this issue, “Realizing Strategic Value through Center-Edge Digital Transformation in Consumer-Centric Industries,” provides a unique opportunity to pay tribute to the first author, Paul Gray, who passed away last year. Please join me in thanking Omar El Sawy, Guillermo Asper, and Magnus Thordarson for continuing to revise this article co-authored with Pau...

Introduction: As a carrier of different sensors, moles can penetrate into the regolith automatically and keep investigating the subsurface environment continuously. In this section, features of several moles with different applications are introduced to explain why we choose a hammer-driven mole to study. Mole driven by a hammer: In this section, the penetrating principle of a hammer-driven mol...

Traumatic dislocation of the head of the radius in children may be either an isolated injury or, more commonly, part of a more complex injury to the elbow, such as the Monteggia fracture-dislocation. in that injury the dislocation of the head of the radius is described as anterior or posterior and the fracture of the ulna affects its shaft (Watson-Jones 1956). Wise (1941) reported a case of lat...

BACKGROUND Radial head prostheses are available with multiple geometric properties. The effect of design features on radiocapitellar stability has not been investigated. HYPOTHESIS The shape (depth and radius of curvature) of the articulating dish of a radial head prosthesis affects radiocapitellar stability. MATERIALS AND METHODS Radiocapitellar stability due to concavity-compression was e...

We measured upper airway caliber and lung volumes in six normal subjects in the sitting and supine positions during 20-s periods in normogravity, hypergravity [1.8 + head-to-foot acceleration (Gz)], and microgravity ( approximately 0 Gz) induced by parabolic flights. Airway caliber and lung volumes were inferred by the acoustic reflection method and inductance plethysmography, respectively. In ...
