Biography:

Qiuhe Peng is mainly engaged in nuclear astrophysics, particle astrophysics and Galactic Astronomy research. In the field of Nuclear Astrophysics, his research project involved a neutron star (pulsar), the supernova explosion mechanism and the thermonuclear reaction inside the star, the synthesis of heavy elements and interstellar radioactive element such as the origin of celestial 26Al. In addition, through his lectures, he establishes Nuclear Astrophysics research in China. He was invited by Peking University, by Tsinghua University (both in Beijing and in Taiwan) and by nuclear physics institutes in Beijing, Shanghai, Lanzhou to give lectures on Nuclear Astrophysics for many times. He has participated in the international academic conferences over 40 times and he visited more than 20 countries. In 1994, he visited eight institutes in USA to give lectures. He is the first Chinese Astrophysicist to visit NASA and to give a lecture on the topic, “Nuclear Synthesis of Interstellar 26Al”. In 2005, he visited USA twice and gave lectures in eight universities again. Inviting six astronomers of USA to give series lectures, he has hosted four consecutive terms summer school on gravitational wave astronomy. After the four summer school obvious effect, at least 20 young scholars in China in the field of gravitational wave astronomy specialized learning and research. 220 research papers by him have been published.

Abstract:

An anomaly strong radial magnetic field near the Galactic Center (GC) is detected[1]. The lower limit of the radial magnetic field at r=0.12 pc from the GC is B≥8mG.
 
It is possible scientific significances are following:
 
• The black hole model at the GC is incorrect. The reason is that radiations observed from the region neighbor of the GC are hardly emitted by the gas of accretion disk due to it being prevented from approaching to the GC by the abnormally strong radial magnetic field[2].
• This is an anticipated signals for existence of magnetic monopoles (MM)[3].
• The lower limit of the detected radial magnetic field is quantitatively in agreement with the prediction of our paper “An AGN model with MM”[4].
• Magnetic monopoles may play a key role in some very important astrophysical problems using the Robakov-Callen effect that nucleons may decay catalyzed by MM.
• Taking the RC effect as an energy source, we have proposed a unified model for various supernova explosion[5], including to solve the question of the energy source both in the Earth core and in the white dwarfs.
• We may explain the physical reason of the Hot Big Bang

Biography:

Takashi Matsuoka is a Professor at the Institute for Materials Research, Tohoku University. He has published more than 100 papers in journals and more than 50 patents including U.S. and EPC patents. In 1980s, he developed the laser diode used for the present optical communications systems. He has also developed nitride semiconductors. He proposed the material concept for blue LEDs and showed how to grow InGaN as an emitting layer. He was the Editor of Applied Physics Express for five years. He is a member of IEEE, MRS, ACerS, SPIE, and several other societies in Japan.

Abstract:

Since the first synthesization of gallium nitride nanorods (GaN) in 1932, high quality GaN could not be obtained for a long term because the equilibrium vapor pressure of nitrogen is a several orders of magnitude higher than the equilibrium pressure of As in gallium arsenide (GaAs) at the growth temperature. For the lack of a GaN substrate, a GaN thin film was epitaxially grown on a sapphire substrate in 1969. A MIS-type GaN LED was fabricated and the first blue emission was observed in 1971. Accidentally, the high quality GaN film with a smooth surface was successively grown through a low-temperature grown AlN buffer layer by the metalorganic vapor phase epitaxy (MOVPE) for the first time in 1986. To construct a double-heterostructure (DH structure) indispensable for a highly efficient LED, InGaAlN was proposed in 1989. This year, InGaN as a material for the blue emission was grown under the sophisticated conditions, and p-GaN was also obtained with Mg doping. The blue LED was fabricated, and became commercially available in 1993. A white LED was developed in 1996, and has been widely used in the solid state lighting. Taking the material characteristics of nitride semiconductors, the first field-effect-transistors of nitride semiconductors was fabricated in 1993. The high electron mobility transistor has been already used in the base stations of cellar phones. The development of high power and high frequency transistors has been increasingly promoted for realizing the sustainable society. Recently, the polarity characteristic in GaN has been attracted for devices with higher performance.

Abstract:

We present a general method for directly estimating 1-D (time-based) or 2-D (spatial domain-based) transfer functions from only irradiance measurements, applicable to linear, time and/or space invariant detection systems. A relevant example of a 2-D linear, space-invariant system is an atmospheric turbulence compensating imaging system. For well designed optical imaging systems, the turbulent atmosphere dominantly and strongly limits the imaging system’s spatial resolution when the entrance pupil aperture is much larger than the atmospheric coherence length r0. In this case, the uncorrected optical imaging system in atmospheric turbulence falls far short of achieving its potential classical diffraction-limited spatial resolution. Atmospheric turbulence compensation (ATC) methods can provide a D/ro improvement in spatial resolution where D is the diameter of the entrance pupil of the imaging systems and ro is the atmospheric coherence length (a.k.a Fried parameter). In this paper, we briefly describe the nature and effects of atmospheric turbulence on passive, incoherent optical imagery (e.g. imaging systems that use natural illumination sources such as sunlight or moonlight), describe the theoretical basis and mathematical underpinnings used to simulate the effects of atmospheric turbulence, describe the model for our direct optical transfer function (OTF) estimation method, and show how our new OTF estimation method applies to representative atmospheric turbulence compensation paradigms. Our OTF estimation method is shown to have increased computational speed, reduced computational and physical complexity, eliminates inherent
computational redundancies, potentially provides higher accuracy in estimating the OTF, and has built-in constraints for faster
solution convergence over contemporary methods.
