Investigation of Sixfold Symmetry of Transition Metal Doped TM₃Si₁₂ Clusters

Fu-bao Zheng 한국자기학회 2024 Journal of Magnetics Vol.29 No.1

This paper employs a genetic algorithm (GA) in conjunction with density functional theory (DFT) to explore a range of tri-transition metal (tri-TM) doped Si₁₂ anti-hexagonal prism clusters, specifically TM₃Si₁₂ clusters featuring either single or dual types of TM atoms. The investigation encompasses neutral, cationic, and anionic states. Our findings reveal that most clusters exhibit remarkable stability and diverse magnetic properties. The HOMO-LUMO gap results for the cluster series are elucidated by an electron-counting rule, providing a more detailed explanation than previous theories.

The electronic and magnetic properties with intrinsic defects in ZnO nanosheets: First-principles prediction

Fu-Bao Zheng,Chang-Wen Zhang,Pei-Ji Wang,Hang-Xing Luan 한국물리학회 2013 Current Applied Physics Vol.13 No.4

Using full-potential linearized augmented plane wave (FLAPW) method, we investigated the effects of intrinsic vacancies on electronic and magnetic properties in graphene-like ZnO nanosheets. The results show that the oxygen vacancy (VO) has no influence on magnetism in ZnO nanosheet, whereas the Zn vacancy (VZn) lead to spin polarization of the nanostructures with a total magnetic moment of 2.0mB due to O-2p and Zn-3d hybridization. When the distance of two VZn defects increases to 6.499 A, the system shows an intriguing half-metallic character with 100% spin-polarized carriers due to O(2p)-Zn(3d)-O(2p) coupling chain between two VZn defects.

A Probe into the Modernity of Chinese Oil Painting

Fu Bao Sui 국제문화기술진흥원 2023 International Journal of Advanced Culture Technolo Vol.11 No.1

Art grows with the development of human civilization.Many art forms exist to connect the past and the future. Oil painting, a form of western painting, has flourished in China since its entry into China.In the continuous exploration of artistic language, Chinese artists have formed art forms with Chinese characteristics, permeated Chinese painting ideas and techniques, and formed specialized painting language.Through the oil painting works, the Chinese oriental aesthetic, national spirit, local customs and other times of humanistic features. As one of the many practitioners of oil painting in China, the author starts from the ego and continuously explores and studies in the practice of art.This paper mainly discusses the embodiment of Chinese oil painting modernity in the oriental art context and analyzes the spiritual temperament and painting materials, so as to expand the creative thinking of Chinese oil painting modernity in the oriental art context.

Bao-Chun Li,Yuan-Yuan Fu,Fu-Hu Liu,Li-Li Wang 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.60 No.7

We investigate the dependence of the elliptic flow v2 on the transverse momentum PT for charged and strange hadrons produced in Cu-Cu collisions at high energy by using a multi-source ideal gas model. A detailed comparison with the experimental results from Cu-Cu collisions at p sNN = 62.4 GeV and 200 GeV, measured by the STAR collaboration, is discussed. Over wider range of PT , the experimental results v2(PT ) are well described by this model.

Multi-Receiver Quantum Dense Coding with a Non-Symmetric Quantum Channel

Chang-Bao Fu,Shou Zhang,엄정인,Ke-Li,연규황 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.5I

A two-receiver quantum dense coding scheme and an N-receiver quantum dense coding scheme, in the case of non-symmetric Hilbert spaces of the particles of the quantum channel, are investigated in this paper. A sender can send his messages to many receivers simultaneously. The scheme can be applied to quantum secret sharing and controlled quantum dense coding.

Controlled Quantum Dense Coding in a Four-Particle Non-Maximally Entangled State via Local Measurements

Chang-Bao FU,연규황 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1

A controlled quantum dense coding scheme is investigated with a four-particle non-maximal quantum channel. The amount of classical information is shown to be capable of being controlledby the controllers through adjustments of the local measurement angles and todepend on the coefficients of the quantum channel; in addition, the four particles are distributed in two inverse ways in such an quantum channel. A restricted condition for distributing the particles to realize quantum dense coding in an arbitrary (N+2)-particle quantum channel is proposed.

Sorafenib Continuation after First Disease Progression Could Reduce Disease Flares and Provide Survival Benefits in Patients with Hepatocellular Carcinoma: a Pilot Retrospective Study

Background: Sorafenib is a promising drug for advanced hepatocellular carcinoma (HCC); however, treatment may be discontinued for multiple reasons, such as progressive disease, adverse events, or the cost of treatment. The consequences of sorafenib discontinuation and continuation are uncertain. Materials and Methods: We retrospectively analyzed 88 HCC patients treated with sorafenib from July 2007 to January 2013. Overall survival (OS), post-disease progression overall survival (pOS), and time to disease progression (TTP) were compared for survival analysis. Cox proportional hazard regression was performed to assess the effect of important factors on OS in the overall patient population and on pOS in patients who continued sorafenib treatment. Results: Sorafenib was discontinued and continued in 24 and 64 patients, respectively. The median OS (355 vs 517 days respectively; p=0.015) and median post-PD OS (260 vs 317 days, respectively; p=0.020) were statistically different between the discontinuation and continuation groups. Neither the median time to first PD nor the time to second PD were significantly different between the 2 groups. In the discontinuation group, 3 of the 24 patients (12.5%) suffered disease outbreaks. In Cox proportional hazard regression analysis after correction for confounding factors, BCLC stage (p=0.002) and PD site (p=0.024) were significantly correlated with pOS in patients who continued sorafenib treatment. Conclusions: Sorafenib discontinuation may cause HCC flares or outbreaks. It is advisable to continue sorafenib treatment after first PD, particularly in patients with Barcelona Clinic Liver Cancer stage B disease or only intrahepatic PD.

Small Non-coding Transfer RNA-Derived RNA Fragments (tRFs): Their Biogenesis, Function and Implication in Human Diseases

Fu, Yu,Lee, Inhan,Lee, Yong Sun,Bao, Xiaoyong Korea Genome Organization 2015 Genomics & informatics Vol.13 No.4

tRNA-derived RNA fragments (tRFs) are an emerging class of non-coding RNAs (ncRNAs). A growing number of reports have shown that tRFs are not random degradation products but are functional ncRNAs made of specific tRNA cleavage. They play regulatory roles in several biological contexts such as cancer, innate immunity, stress responses, and neurological disorders. In this review, we summarize the biogenesis and functions of tRFs.

Objective: The purpose of this study is to determine the optimal time of transportation of floor-feed and scatter-feed broilers. Methods: Eighty healthy Arbor Acres (AA) broilers (21-day-old, 624.4 g, male, standard error = 6.65) were selected and randomly divided into two experimental groups (floor-feed and scatter-feed), then fed for three weeks. The experiment comprised a 2×4 factorial design with 2 feed patterns (floor-feed and scatter-feed) and 4 transport periods (2, 3, 4, and 5 h), and 4 replicates of 5 broilers (54-day-old, 2243 g, standard error = 46.65) was used to compare weight loss, meat quality and behavior index of different groups. Results: It appeared that drip loss, meat color and resting behavior of experimental broilers changed as length of transportation (p<0.05), however, weight loss and pH were not significantly transformed (p>0.05). Compared with floor-feed group, broilers in scatter-feed group had lower pH at 24 hours (3 h) and different behavioral indicators (p<0.05). Especially indicators after 3 h transportation, there were obvious differences between the two feeding modes in the behavior reaction of stress events before slaughter with different transport duration (p<0.05). The fluctuation of data on resting behavior with scatter-feed was significantly higher than that of floor-feed broilers. There was no interaction between transport time and different feeding methods for index tested of our experiment (p>0.05). Conclusion: Comprehensive analysis showed that the maximum transport duration of floor-feed and scatter-feed broilers should not exceed 3 h, and scatter-feed broilers were more likely prone to fear.
