Reduction of Corrugation by Semi-Active Track

open access: yes, 2004
This article discusses possibilities for application of semi-active actuators to reduce rail and wheel wear. A simple model of a vehicle/track interaction is presented. The model is extended with a model of semi-active actuators. The feedback control law

Re‐Awakening Public Attention to the Silent Pandemic of Cancer Among Older Adults in Low‐ and Middle‐Income Countries

open access: yesAging and Cancer, EarlyView.
ABSTRACT As global populations age, cancer is increasingly becoming a leading cause of morbidity and mortality among older adults, particularly in low‐ and middle‐income countries (LMICs). Despite accounting for the majority of new cancer cases and deaths, older individuals remain underrepresented in cancer research, clinical guidelines, and health ...

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

A TRIGGERED LIQUID TRACK CHAMBER WITH SHORT RESOLVING TIME [PDF]

open access: yesNuclear Instruments and Methods, 1963
The principle of a new type of track detector is described. Bubbles of gas are produced in oil by injection through a porous surface at the bottom of an oil container with transparent walls. An electric field can be applied to the liquid by means of plane electrodes.
