The auxiliary power supply (APS) is one of the critical components inside medium-voltage (MV) power converters. Besides high insulation capability and small footprint, low common-mode (CM) coupling capacitance and multichannel output are the desired features of APS in the emerging silicon-carbide-based MV converters du... |
BACKGROUND AND OBJECTIVE |
Rapid progress in computer and information technologies has led to an increased interest in the use of telemedicine during the past few years. Thus it should be clarified, whether teledermatology can achieve comparable results to conventional specialist examination and advice. |
PATIENTS/METHODS |
We initiated a pilot study, comparing teledermatology with conventional examination in a dermatology outpatient setting. 60 patients were included. |
RESULTS |
Out of 60 teledermatological examinations, remote clinicians were in agreement with face-to-face clinicians in 90%. Teledermatology was unable to make a useful diagnosis in 6 patients, however further diagnostic procedures were ordered, enabling teledermatologists to achieve correct diagnoses. Regarding need for furthe... |
CONCLUSIONS |
Teledermatology appears suitable to transfer a dermatologist's expertise over large distances.Supportive care for children and young people during cancer treatment. |

Morrison (this issue) criticized the analytical and statistical methods that Escudero and Boersma (2004) used for assessing the participants' cue weightings in their listening experiments. He proposed that logistic regression constitutes a better method for measuring perceptual cue weighting than Escudero and Boersma's... |
Caching popular content at small base stations (SBSs) of a wireless edge network is a good choice to reduce user request latency and backhaul load. However, an effective coded caching scheme to solve the challenges in hierarchical cacheenabled networks (HCENs), including the limited SBS cache capacity, rich content amo... |
In ‘Salvaging the Concept of Nudge’ Yashar Saghai performs an important clarificatory task which certainly advances our philosophical and ethical understanding of nudges in public policy, and in healthcare ethics in particular.1 In this brief commentary I identify some issues which could usefully be taken forward in su... |
A central difficulty with ethical discussions of nudging is that insufficient care is taken to distinguish two morally important features of nudges. The first, which Saghai very properly concentrates upon, is the mechanism of nudging. Nudges rely on psychological properties of human decision-makers as the way in which ... |
We apply the theory of the inhomogeneous Kibble-Zurek mechanism to understand the quench dynamics in the transition from a Mott insulator to a superfluid in a cold Bose gas confined in both a two-dimensional optical lattice and a harmonic trap. The local quench time and the resulting Kibble-Zurek diabatic-adiabatic bou... |

The low profile and wide bandwidth of microstrip stacked-patch antennas makes them an attractive choice for many RF applications, especially in the UHF and L bands. There are competing factors that impact the design of these antennas. For instance, miniaturization can be achieved through the use of substrates with a hi... |
We consider the ordinary differential equation of the second order x/spl uml/+/spl psi/(/spl epsi/t) sin(x-/spl phi/(/spl epsi/t))=0 with the coefficients /spl psi/ and /spl phi/ depending slowly on time. By using a Wentzel-Kramers-Brillouin (WKB)-like method we construct two asymptotic series for a general solution of... |

Thus, this research aimed to investigate POLR1D’s expression and significance in human CRC patients and... |
After the First World War the professional medical societies in Hungary, which have already organized themselves nationwide, started to operate independently from each other. In that time came the idea to create another association above the others to gather them together while retaining their independent functioning. ... |
This paper provides a complete LMI solution to the gain-scheduling controller synthesis problem with frequency-dependent D-scalings. This extension of Packard's seminal work for constant D-scalings paves the way for a considerable reduction of conservatism. Apart from the technical result, we sketch potential applicati... |
Because of the requirement of reporting effect sizes and in the interest of measurement of change within the item response theory framework, their combination becomes a new issue. In the present study, repeated measures are decomposed as an initial ability and one or more modifiabilities (gain score) using a multidimen... |
Therapy with the oral antidiabetic agent troglitazone (Rezulin) has been associated with cases of severe hepatotoxicity and drug-induced liver failure, which led to the recent withdrawal of the product from the U.S. market. While the mechanism of this toxicity remains unknown, it is possible that chemically reactive me... |
The blood–brain barrier (BBB) limits the access of drugs to the brain. Intensive research is being conducted on the development of nanoparticulate drug carriers that mediate transfer across the BBB. A question that has been neglected so far is the potential accumulation of the carrier in the brain upon long‐term exposu... |
Adopting the use of real-time odour monitoring in the smart home has the potential to alert the occupant of unsafe or unsanitary conditions.

OBJECTIVE |
To determine the response, in terms of fecal hemoglobin excretion and clinical symptoms, of normal 9 1/2-month-old infants to being fed cow milk. |
DESIGN |
Longitudinal (before-after) trial in which each infant was fed formula for 1 month (baseline) followed by 3 months during which cow milk was fed. |
SETTING |
Healthy infants living in Iowa City, Iowa, a town with a population of about 60,000. |
MAIN OUTCOME MEASURES |
Hemoglobin concentration in spot stools, 96-hour quantitative fecal hemoglobin excretion, stool characteristics, feeding-related behaviors, and iron nutritional status. |
RESULTS |
Fecal hemoglobin concentration during formula feeding (baseline) was higher than previously observed in younger infants. Nine of 31 infants responded to cow milk feeding with increased fecal hemoglobin concentration. Fecal hemoglobin concentration (mean +/- SD) of the 9 responders rose from 1,395 +/- 856 microg/g of dr... |
CONCLUSIONS |
Cow milk-induced blood loss is present in 9 1/2-month-old infants but is of such low intensity that its clinical significance seems questionable. Nevertheless, infants without cow milk-induced blood loss were in better iron nutritional status than infants who showed blood loss.A 4.9mW 270MHz CMOS frequency synthesizer/... |
