We present a quantitative model, called metric hybrid automata, for quantifying the behaviors of complex physical systems, such as chemical reaction control systems, manufacturing systems etc. Due to the introduction of a metric, the state space of hybrid automata forms a metric space, in which the difference of states can be quantified. Furthermore, in order to reveal the distance of system behaviors, we construct the simulation distance and the bisimulation distance, which quantify the similarity of system behaviors. Our model provides the basis for quantitative analysis for those complex physical systems.

Most existing commercial real-time polymerase chain reaction (RT-PCR) instruments are bulky because they contain expensive fluorescent detection sensors or complex optical structures. In this paper, we propose an RT-PCR system using a camera module for smartphones that is an ultra small, high-performance and low-cost sensor for fluorescence detection. The proposed system provides stable DNA amplification. A quantitative analysis of fluorescence intensity changes shows the camera’s performance compared with that of commercial instruments. Changes in the performance between the experiments and the sets were also observed based on the threshold cycle values in a commercial RT-PCR system. The overall difference in the measured threshold cycles between the commercial system and the proposed camera was only 0.76 cycles, verifying the performance of the proposed system. The set calibration even reduced the difference to 0.41 cycles, which was less than the experimental variation in the commercial system, and there was no difference in performance.

The Impact

Heat removal in packaged high-power light-emitting diode (LED) chips is critical to device performance and reliability. Thermal performance of LEDs is important in that lowered junction temperatures extend the LED's lifetime at a given photometric flux (brightness). Optionally, lower thermal resistance can enable increased brightness operation without exceeding the maximum allowable Tj for a given lifetime. A significant portion of the junction-to-case thermal resistance comes from the joint between chip and substrate, or the die-attach layer. In this study, we evaluated three different types of leading die-attach materials; silver epoxy, lead-free solder, and an emerging nanosilver paste. Each of the three was processed via their respective physical and chemical mechanisms: epoxy curing by cross-linking of polymer molecules; intermetalic soldering by reflow and solidification; and nanosilver sintering by solid-state atomic diffusion. High-power LED chips with a chip area of 3.9 mm2 were attached by the three types of materials onto metalized aluminum nitride substrates, wire-bonded, and then tested in an electro-optical setup. The junction-to-heatsink thermal resistance of each LED assembly was determined by the wavelength shift methodology, described in detail in this paper. We found that the average thermal resistance in the chips attached by the nanosilver paste was the lowest, and it is the highest from the chips attached by the silver epoxy: the difference between the two was about 0.7°C/W, while the difference between the sintered and soldered was about 0.3°C/W. The lower thermal resistance in the sintered joints is expected to significantly improve the photometric flux from the device. Simple calculations, excluding high current efficiency droop, predict that the brightness improvement could be as high as 50% for the 3.9 mm2 chip. The samples will be functionally tested at high current, in both steady-state and pulsed operation, to determine brightness improvements, including the impact of droop. Nanosilver die-attach on a range of chip sizes up to 12 mm2 are also considered and discussed.

Abstract Background Tetralogy of Fallot (TF) is a rare disease characterized by the presence of 4 congenital heart defects (CHD). Objective: to describe the temporal trend and distribution of the TF in the Valencia Region (VR), in less than one year old, during the period 2007-2016. Methods Live births, stillbirths and termination of pregnancy due to fetal anomaly (TOPFA) between 2007-2016 with TF (code Q21.3 of the ICD10-BPA) were selected from the Congenital Anomalies (CA) population-based Registry of VR. The cases were confirmed through the review of clinical documentation. The prevalence of 10000 births with 95% confidence intervals (95%CI) was calculated for the period and for each year, and a descriptive analysis of sociodemographic and clinical variables was made. Results 146 cases were identified (45.2% male, 31.5% female and 23.3% unknown), 89.0% were simple pregnancies and 54.8% were diagnosed prenatally. The overall prevalence of TF was 3.0/10000 births (95%CI: 2.5-3.5), being 2015 the year with the highest prevalence (4.3/10000 births) and 2011 with the lowest (1.8/10000 births). These changes were mainly due to the increase and decrease in the number of TOPFA respectively. 74.7% were live births, 22.6% TOPFA and 2.7% stillbirths. The prevalence in live births was 2.2/10000 births (95%CI: 1.8-2.6) and in TOPFA it was 0.7/10000 births (95%CI: 0.4-0.9), identifying an increasing trend during the period in the last one. 11.0% of live births died during the first year of life. 45.9% of the cases had another CA associated with the TF, being CHD in 52.7% of cases. 66.4% of the mothers were over 30 years of age, being the most frequent those between 30-34 years (30.1%). Conclusions The prevalence obtained in the VR was lower than that of EUROCAT 3.5/10000 births (95%CI: 3.3-3.6) during the same period. EUROCAT has also identified the difference between the prevalence in live births (2.9 (95%CI: 2.8-3.0)) and TOPFA (0.5 (95%CI: 0.5-0.6)), and the increasing trend in the last one. Key messages The prevalence of Tetralogy of Fallot obtained in the VR was lower than that of EUROCAT (European network of population-based registries for the epidemiologic surveillance of congenital anomalies). EUROCAT has also identified the difference between the prevalence of Tetralogy of Fallot in live births and termination of pregnancy due to fetal anomaly, and the increasing trend in the last one.

Abstract Relaxation in relatively stable, gum natural rubber vulcanizates has been studied to determine the effects of viscoelasticity and aging, respectively, using a dark, air-oven. A quantitative analysis of experimental results shows that, in the case of a dicumyl peroxide vulcanizate at 100° C, relaxation is caused by aging, except in its initial stages. Stress decreases as a linear function of time, in agreement with theoretical assumptions. Conversely, at 30° C, the effect of aging is negligible. At this temperature the difference between actual stress and stress extrapolated to infinite time, is proportional to a negative power of time. At intermediate temperatures, both phenomena occur simultaneously over a time interval ranging from. 3 minutes to 150 hours.

The Difference

Median values of the fwhm and equivalent width Wλ of the C iv 581 nm, O v 559 nm and 465 nm emission lines were derived from an extended statistical analysis of WC and WO stars (Norci et al. 2002; see Table 1). We find that the C iv equivalent width shows an increasing trend towards earlier WC subtypes, reaching a maximum value of 95 nm (± 32 %) for the Galactic WC4-6 stars, and decreases by about a factor of three in the hotter WO stars (Figure 1, left). The line appears about twice as strong in the LMC than in the Galactic WC4 stars, and the difference is particularly evident in the non-Galactic WO stars. Such an effect is absent in the O v 559 nm line, which smoothly increases towards WCE and WO stars, with no significant difference between Galactic and non-Galactic WC4 and WO stars. Thus this C anomaly is not an ionization effect; it is, therefore, probably due to a cause that selectively operates on C rather than on O. Different physical conditions in the winds of Galactic and non-Galactic stars, possibly related to the different initial metallicity Z, could be responsible for the anomaly.

The junction-to-heatsink thermal resistance of each LED assembly was determined by the wavelength shift methodology. We found that the average thermal resistance in the chips attached by the nanosilver paste was the lowest, and it was highest from the chips attached by the silver epoxy. For the 3.9 mm2 die, the difference was about 0.6°C/W, while the difference between the sintered and soldered was about 0.3°C/W. The lower thermal resistance in the sintered joints is expected to significantly improve the photometric flux from the device. Simple calculations, excluding high current efficiency droop, predict that the brightness improvement could be as high as 50% for the 3.9 mm2 chip. The samples will be functionally tested at high current, in both steady-state and pulsed operation, to determine brightness improvements, including the impact of droop. Nanosilver die-attach on a range of chip sizes up to 12 mm2 are also considered and discussed.
