The microwave microscope is a device which utilises near fields to characterise material properties of samples on length scales smaller than the operating wavelength. The errors associated with extracting the permittivity of a high permittivity thin film on a low permittivity substrate from measurements using such a device are found to be of the order of 25% when using a widely used image charge model of the tip-sample interaction. The uncertainties arise from the model-based extraction of the permittivity from the raw frequency shift data, and in the current case are shown to come from the assumption in the model that the tip of the microwave probe can be modelled as a sphere.
The raw data from the microscope contain random uncertainties of the order of 1% and reveal variations in the properties of the thin film with sub-wavelength resolution demonstrating the microwave microscope as a sub-wavelength characterisation technique for thin films.
The idea of a returning golden age (or, more properly, a renascent golden race1) is widely understood and commonly presented both as a staple of Augustan propaganda and as a pervasive aspiration of Augustan society. TheCarmen Saeculare—an official commission for a public festival—is presented as a means by which the regime proclaimed to an enthusiastic populace the imminent renascence of the golden race. The aim of this article is to draw attention both to thefailureof theCarmen Saeculareexplicitly to proclaim the renascence of the race, and to the critique implicit in the poem of the very idea of a renascence. The golden race, according to this reading, might be undesirable on account of its very goldenness. The golden race was the subject of a complex myth at the centre of a complex discourse: neither the ‘official’ nor the popular response to the idea of its return can have been as simple as they are frequently portrayed.
I work as a ward manager on a 20-bed continuing care ward with some input into a respite care facility. My clinical area caters for older people who have neurological conditions, most commonly Alzheimer's disease, Lewy body disease and vascular dementia. I found this article to be of great benefit and I am certainly aware of the difficulties associated with maintaining the safe mobility of our patients. I intend to make greater use of my communication skills and especially non-verbal communication.
Working with people with dementia, I am very aware of many of the ethical and legal implications surrounding the issue of capacity and consent. I believe that we have a number of reasonable safeguards regarding the administration of medicines in my clinical area but have to admit that in the past we have been involved in the covert administration of medication with strange tasting tea, crunchy porridge and the infamous spoon of jam. The turning point came when one of our patients refused to have an injection that was due and, when faced with this, we realised that we could not simply go ahead and give it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
