| 1 | All-silicon carrier accumulation modulator based on a lateral metal-oxide-semiconductor capacitor显示文摘In silicon photonics, the carrier depletion scheme has been the most commonly used mechanism for demonstrating high-speed electro-optic modulation. However, in terms of phase modulation efficiency, carrieraccumulation-based devices potentially offer almost an order of magnitude improvement over those based on carrier depletion. Previously reported accumulation modulator designs only considered vertical metal-oxidesemiconductor(MOS) capacitors, which imposes serious restrictions on the design flexibility and integratability with other photonic components. In this work, for the first time to our knowledge, we report experimental demonstration of an all-silicon accumulation phase modulator based on a lateral MOS capacitor. Using a Mach–Zehnder interferometer modulator with a 500-μm-long phase shifter, we demonstrate high-speed modulation up to 25 Gbit∕s with a modulation efficiency(V_πL_π) of 1.53 V·cm. | KAPIL DEBNATH DAVID J.THOMSON WEIWEI ZHANG ALI Z.KHOKHAR CALLUM LITTLEJOHNS JAMES BYERS LORENZO MASTRONARDI MUHAMMAD K.HUSAIN KOUTA IBUKURO FREOERIC Y.GARDES GRAHAM T,REED SHINICHI SAITO | 2018 | Photonics Research2018，6，5： | 6 |
| 2 | Helianthus tuberosus(Jerusalem artichoke) tubers improve glucose tolerance and hepatic lipid profile in rats fed a high-fat diet显示文摘Objective:To analyze the effects of feeding Helianthus tuberosus(HT) tubers on glucose tolerance and lipid profile in rats fed a high-fat diet(HFD). Methods:A normal HFD or HFD including 10 w/w% HT tubers(HFD + HT) was fed to F334/Jcl rats. After 10 weeks,organ weights,glucose tolerance,and lipid profile were analyzed. Results:The body weight,liver weight,and epidermal fat content in the HFD group were higher than those of the normal group,and similar to those of the HFD + HT group. The oral glucose tolerance test at 10 weeks revealed that the blood glucose level 30 minutes after beginning the test in the HFD + HT group was significantly lower than that in the HFD group. Liver triglyceride and total cholesterol levels in the HFD + HT group were significantly lower than those in the HFD group. Fecal triglyceride and total cholesterol levels in the HFD + HT group were higher than those in the HFD group. Histological analyses revealed that fat and glycogen accumulation increased in the HFD group,but decreased in the HFD + HT group. Conclusions:These results indicate that HT tubers have anti-fatty liver effects based on improvements in glucose tolerance and the hepatic lipid profile. | Naoto Okada Shinya Kobayashi Kouta Moriyama Kohsuke Miyataka Shinji Abe ChiemiSato Kazuyoshi Kawazoe | 2017 | Asian Pacific Journal of Tropical Medicine2017，10，5： | 2 |
