Direct modulation at 56 and 50 Gb/s of 1.3-μm InGaAlAs ridge-shaped-buried heterostructure (RS-BH) asymmetric corrugation-pitch-modulation (ACPM) distributed feedback lasers is experimentally demonstrated. The fabricated have a low threshold current (5.6 mA 85°C), high temperature characteristics (71 K), slope relaxation frequency (3.2 GHz/mA1/2 wide bandwidth (22.1 GHz 85°C). These superior properties enable the to run 55°C up 80°C for backto-back operation with clear eye openings. This...
We investigated palliative care knowledge, difficulty and self-reported practice among a region-wide sample of nurses who cared for cancer patients in Japan. A cross-sectional questionnaire survey was distributed to 9 designated centers, 17 community hospitals 73 district nurse services across 4 regions 2008. used the Palliative Care Knowledge Test, Difficulty Scale (five-point Likert scale) Self-Reported Practices scale). In total, 2378 out 3008 (79%) responded. The scores were 51 ± 20%,...

Our previous study indicated that coadministration of tramadol and minocycline exerted synergistic effects on spinal nerve ligation (SNL)-induced neuropathic mechanical allodynia. However, the underlying mechanisms are still unclear. Recent reports proinflammatory factor interleukin-1β (IL-1β) contributed to development pain positive feedback communication between neuron glia. Therefore, present research is confirm whether IL-1β-related pathway response contributes SNL-induced pain....
We have investigated optical nonlinearity in beryllium-doped low-temperature (LT) molecular-beam-epitaxy-grown GaAs/AlAs multiple quantum wells (MQWs). The response time of the is reduced by Be doping MQW. While undoped LT MQW shows a 0.7–0.9 ps response, Be-doped as short 0.25 ps. saturation density almost same that MQW, and smaller than bulk GaAs. These results demonstrate exhibits faster well larger
Uncooled 53-Gbaud PAM4 operation of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1.3-\mu \text{m}$</tex> electro-absorption modulator integrated DFB laser was demonstrated with 0.9 Vpp for the first time. We obtained extinction ratio more than 4.9 dB and TDECQ less 2.3 from 20 to 85°C.
During laryngoscopy, the laryngoscope blade sometimes comes in contact with teeth, fracturing or dislocating them. However, no studies have compared effects of newly marketed video laryngoscopes and Macintosh (Mac) on teeth. In this study, we measured force exerted teeth an intubating manikin by Mac, Airway Scope (Pentax), McGrath MAC (Covidien). The mean was 141.1 ± 15.7 kg 39.2 10.3 Scope, 48.7 6.7 MAC. No significant difference observed between When Mac is inserted, glottis has to be...
High speed InP lasers have been developed for 400Gbit/s interconnections. Electro-absorption modulator integrated DFB were demonstrated 106-Gbit/s PAM4 with 0.9 Vpp from 20 to 85°C. eye-openings obtained using directly modulated 25 80°C.
Uncooled 112-Gb/s and 106-Gb/s PAM-4 directly modulated BH lasers are reviewed. High frequency properties of submicron ridge localized buried heterostructure achieve modulation from 25°C to 85°C. Moreover, low BER values below KP4 FEC threshold demonstrated with uncooled direct modulation.
Particulate matters (PM), SOx and NOx in exhaust gases emitted from marine diesel engines may cause serious problems human health coastal environments.Therefore, their emissions have been regulated MARPOL Treaty 73/78 Annex VI of IMO Air Pollution Control since 2005.In this paper, the reduction PM for was investigated using an electrostatic precipitator (ESP) with a heat exchanger.Experiments were carried out to confirm PM, which Dry soot, Soluble Organic Fraction (SOF) sulphate.The...
Purpose: Loss of molar teeth in rats has been reported to be associated with impairment spatial memory, which may related hypo function the hippocampus. However, effects tooth loss on higher brain functions still remain unclear. In present study, glutamate levels hippocampus were measured as an index hippocampus, order elucidate neurochemical changes edentulous rats.Methods: At start this 4-week-old male Sprague-Dawley divided into 3 groups: EXT, all maxillary extracted; ANE, anesthesia was...
We firstly demonstrate incoherent multiplexing of two NRZ signals utilizing directly modulated lasers transmits 106-Gb/s/lane PAM-4 over 10 km without non-linear compensation. Skewless eye diagram this method attained lower BERs than conventional method.
Although numerous electromyographic (EMG) studies of muscle activity have been performed, few examined in detail the relationship between respiratory state and activity. This is primarily because muscles involved respiration are situated deep body, making EMG assessment extremely difficult due to high noise levels. In a previous study, we how changes breathing pattern affect accessory inspiratory neck during spontaneous breathing. The results indicated that could be quantitatively analyzed...
