Effective estimation of the minimum number of amino acid residues required for functional divergence between duplicate genes

Jingqi Zhou, Dangyun Liu, Zhining Sa, Wei Huang, more

Molecular Phylogenetics and Evolution > 2017 > 113 > C > 126-138

One of hot research foci has always been predicting amino acid residues underlying functional divergence after gene duplication, as those predicted sites can be used as candidates for further functional experimentations. It is important and interesting to know how many sites, on average, may have been responsible for the functional divergence between duplicate genes. In this article, we studied two...

Enhanced fluorescence properties of type-I and type-II CdTe/CdS quantum dots using porous silver membrane

Ung Thi Dieu Thuy, Weon-Sik Chae, Won-Geun Yang, Nguyen Quang Liem

Optical Materials > 2017 > 66 > C > 611-615

This paper reports the metal-induced fluorescence property on the CdTe/CdS core/shell quantum dots (QDs), which exhibit the systematic band-gap transition from type-I to type-II with increasing shell thickness, near porous silver membrane by using time-resolved fluorescence lifetime imaging microscopy (FLIM). The results revealed that notable fluorescence enhancement came from the closed location...

Experimental investigation on the flow instability behavior of a multi-channel boiling natural circulation loop at low-pressures

Vikas Jain, A.K. Nayak, P.K. Vijayan, D. Saha, more

Experimental Thermal and Fluid Science > 2010 > 34 > 6 > 776-787

Natural circulation as a mode of heat removal is being considered as a prominent passive feature in the innovative nuclear reactor designs, particularly in boiling-water-reactors, due to its simplicity and economy. However, boiling natural circulation system poses many challenges to designer due to occurrence of various kinds of instabilities such as excursive instability, density wave oscillations,...

Type-I GaSb-Based Laser Diodes Operating in 3.1- to 3.3- $\mu$ m Wavelength Range

Takashi Hosoda, Gela Kipshidze, Gene Tsvid, Leon Shterengas, more

IEEE Photonics Technology Letters > 2010 > 22 > 10 > 718 - 720

Type-I quantum-well (QW) diode lasers based on AlInGaAsSb-InGaAsSb-AlInGaAsSb heterostructure active region with narrow waveguide and high indium content in the barrier were fabricated. Room-temperature continuous-wave output power of 190, 165, and 50 mW for devices emitting 3.1, 3.2, and 3.3 μm correspondingly were demonstrated. Experiment shows that improvement of the hole confinement in QWs by...

Open Physics > 2009 > 7 > 4 > 654-662

This review covers recent advances in superconductivity of diamond, Si, SiC, group III–V and II–IV semiconductors, metal-intercalated graphite and fullerites. The results are critically analyzed and prospects are given for future research directions. In particular, it is argued that the highest transition temperatures of ∼9 K in diamond and 11.5 K in CaC6 can further be enhanced and that no reliable...

Effect of Quantum Well Compressive Strain Above 1% On Differential Gain and Threshold Current Density in Type-I GaSb-Based Diode Lasers

Jianfeng Chen, D. Donetsky, L. Shterengas, M.V. Kisin, more

IEEE Journal of Quantum Electronics > 2008 > 44 > 12 > 1204 - 1210

InGaAsSb/AlGaAsSb quantum well (QW) diode laser structures with either 1% or 1.5% compressively strained QWs were grown on GaSb substrates by molecular beam epitaxy. Wide-stripe lasers fabricated from structures of both types have room-temperature operating wavelengths near 2.3 microns. The room-temperature threshold current density of 1-mm-long uncoated devices with 1.5% strained QWs was lower than...

Soluble type-I interleukin-1 receptor blocks chicken IL-1 activity

K.C. Klasing, R.K. Peng

Developmental and Comparative Immunology > 2001 > 25 > 4 > 345-352

The ligand-binding domain of the chicken type-I interleukin-1 (IL-1) receptor (soluble IL-1R _I ; sIL-1R _I ) was cloned into a Pichia pastoris expression system and the resulting sIL-1R _I binding protein was used to produce antisera in rabbits (anti-IL-1R _I ). Two experiments were conducted to determine the capacity of sIL-1R _I or anti-IL-1R _I to block...
