In this letter, a magnetic dipole (M-dipole) and an electric dipole (E-dipole) are designed to form a collocated polarization-diversity-based dual-antenna system. The M-dipole is a modified shielded loop with multiple feed, and the E-dipole is a traditional λ/2 dipole. Measured results show that both radiators have ideal impedance matching and port isolation and identical omnidirectional pattern w
When offered participation in clinical trials, families of children with cancer face a delicate balance between cure and toxicity. Since parents and children may perceive this balance differently, this paper explores whether adolescent patients have different enrollment patterns compared to younger children in trials with different toxicity profiles.
PURPOSE:: To describe riboflavin and ultraviolet light (UV) collagen crosslinking as an effective treatment for infectious keratitis. METHODS:: A 25-year-old previously healthy female contact lens user was diagnosed with unilateral severe keratitis with unclear pathogenesis, although the clinical presentation suggested acanthamoeba as the infectious agent. A 4-mm diameter, annular, semi-opaque inf
Objective To investigate the reproductive and oncologic outcome following robotic radical trachelectomy for early stage cervical cancer. Methods All women with early stage cervical cancer planned for fertility-sparing robotic trachelectomy between December 2007 and April 2015 at two tertiary referral centers in Sweden were identified. Perioperative- and follow-up data was retrieved from prospectiv
The semiconductor technology development makes it possible to fabricate increasingly advanced integrated circuits (ICs). However, because of imperfections at manufacturing, each individual IC must be tested. A major problem at IC manufacturing test is the increasing test data volume as it leads to high automatic test equipment (ATE) memory requirement, long test application time and low throughput
OBJECTIVES: This study investigated the exposure-response relationships of hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA) and evaluated the applicability of the total plasma protein adducts (TPPA) of these anhydrides as biomarkers of exposure and risk. METHODS: In a cross-sectional study of 139 workers in a plant manufacturing electrical capacitors, the long-term
An efficient method is proposed for the evaluation of the absorption and the transport scattering coefficients from a time-resolved reflectance or transmittance distribution. The procedure is based on a library of Monte Carlo simulations and is fast enough to be used in a nonlinear fitting algorithm. Tests performed against both Monte Carlo simulations and experimental measurements on tissue phant
In dense passive radio frequency identification (RFID) systems, code division multiple access (CDMA) techniques can be used to alleviate severe collisions and thus enhance the system performance. However, conventional CDMA techniques are challenging to implement, especially for passive tags due to cost and power constraints. In this paper, we design a CDMA-based multi-reader passive ultra high fre
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
Objectives: Knowledge of the societal costs of psoriasis is limited. This study estimated the cost of care, psoriasis area and severity index (PASI), and quality of life in a defined patient population in Sweden. Methods: A prevalence-based prospective recruitment of patients visiting two Swedish dermatology clinics between September and December 2009 was performed, collecting resource utilization
ad transport of dangerous goods is due to its inherent risk associated with a potential impact far higher than the small volumes might suggest, and has therefore been the target of numerous ITS-related initiatives. However, there are few indications of actual working ITS solutions for dangerous goods. In this paper we conduct an empirical investigation of past projects and research to analyze the
Gas phase polyethylene reactors are able to produce several different grades of polymer. Adapting to market conditions requires grade transitions, associated with costs in terms of raw material and temporary production of lower priced off-specification products. In this paper, both stationary production and dynamic grade transitions are optimized to maximize profit, i.e., economic process optimiza
