Telemedicine: Still a lot of static

A polyhedral study of the static probabilistic lot-sizing problem

We study the polyhedral structure of the static probabilistic lot-sizing problem and propose valid inequalities that integrate information from the chance constraint and the binary setup variables. We prove that the proposed inequalities subsume existing inequalities for this problem, and they are facet-defining under certain conditions. In addition, we show that they give the convex hull descr...

Technological Unemployment but Still a Lot of Work: Towards Prosumerist Services of General Interest

This article explores the impact of both technological unemployment and a basic income on the provision of services of general interest. A basic income may promote the restructuring of production into postcapitalist forms and projects involving peer production. This change, as well as technological unemployment, will result in lower state and market capacities to provide services. Instead, peop...

Telemedicine: A systematic review of economic evaluations

Background: Telemedicine is an expanded term in health information technology that comprises procedures for transmitting medical information electronically to improve patients’ health status. The objective of this research is to evaluate the cost-effectiveness of telemedicine interventions in various specialty areas.    Methods: The Cochrane Library and Centre for Review and Di...

Shared mechanisms of ischaemic and haemorrhagic stroke: still a lot to learn.

T he risk of intracerebral haemorrhage (ICH) is increased in patients with ischaemic cerebrovascular disease and vice versa. Risk factors shared by both stroke subtypes, such as hypertension, age, and smoking, partly explain this observation. While some researchers stress that most ischaemic stroke subtypes have similar risk factor profiles, one can go further and claim that most strokes (ischa...

Nonthoracotomy defibrillator lead systems. A welcomed addition but still a lot to learn.
