A meandered and a spiral stacked circular planar inverted–F antennas (PIFAs) are proposed for integration into head–implantable biomedical devices and wireless biotelemetry in the 402–405 MHz Medical Implant Communications Service (MICS) band. Designs only differ in the patch shape, feed, and shorting pin positions, while emphasis is given on miniaturization and biocompatibility. Phantom–relate...

This book is intended for radiation and medical physicists, biomechanical engineers, radiation oncologists and clinicians who are involved in the assessment and treatment of patients requiring close-distance radiation, which is defined as "brachytherapy". This book is a very comprehensive description of brachytherapy with emphasis on physics. It is an excellent book for physicists and biomedica...

carbon nanotubes (cnts) are high aspect ratio allotropes of carbon. because of their unique physical and chemical characteristics, they are nominated for a vast variety of applications in the biomedical field. their very low solubility is the only problem of them which is solved by different methods of functionalization. after discoveries in the last few years of the capacity of cnts to penetra...

Biomedical signal databases generally are built for reference purposes. In order to make use of such reference databases, a physiological or medical question first has to be specified. Like in any medical study, hypotheses have to be formulated before setting up a biomedical signal database. The questions posed and the hypotheses formulated naturally lead to the design of a study protocol. The ...

This paper presents the perspectives of personnel involved in decision-making about devices in critical care. We use the concept of "sharp and blunt ends" of practice to describe the performance of health care professionals. The "sharp end" is physically and temporally close to the system; the "blunt end" is removed from the system in time and space and yet affects the system through indirect i...

Medical technology professionals have many avenues to learn new skills, from manufacturer training to continuing education to attending conferences and keeping up on literature in the industry. But what about a way to build your own skills and benefit your employer, all for the cost of a few weeks of leave time and, as an added bonus, helping out others in need? There are many volunteer opportu...

Each year millions of nonhuman animals suffer in biomedical experiments for human health benefits. Clinical ethics demand that nonhuman animals are used in the development of pharmaceuticals and vaccines. Nonhuman animals are also used for fundamental biomedical research. Biomedical research that uses nonhuman animals is big business but the financial gains are generally occluded. This paper ex...

In this paper we propose an integrative model of habituation of reinforcer effectiveness (HRE) that links behavioral- and neural-based explanations of reinforcement. We argue that HRE is a fundamental property of reinforcing stimuli. Most reinforcement models implicitly suggest that the effectiveness of a reinforcer is stable across repeated presentations. In contrast, an HRE approach predicts ...
