A prediction of neutrino mixing matrix with CP violating phase

The latest experimental progress have established three kinds of neutrino oscillations with three mixing angles measured to rather high precision. There is still one parameter, i.e., the CP violating phase, missing in the neutrino mixing matrix. It is shown that a replay between different parametrizations of the mixing matrix can determine the full neutrino mixing matrix together with the CP violating phase. From the maximal CP violation observed in the original Kobayashi-Maskawa (KM) scheme of quark mixing matrix, we make an Ansatz of maximal CP violation in the neutrino mixing matrix. This leads to the prediction of all nine elements of the neutrino mixing matrix and also a remarkable prediction of the CP violating phase $\delta_{\rm CK}=(85.48^{+4.67(+12.87)}_{-1.80(-4.90)})^\circ$ within $1\sigma (3\sigma)$ range from available experimental information. We also predict the three angles of the unitarity triangle corresponding to the quark sector for confronting with the CP-violation related measurements.Comment: 9 pages.

The Majorana neutrino mass matrix indicated by the current data

The Majorana neutrino mass matrix combines information from the neutrino masses and the leptonic mixing in the flavor basis. Its invariance under some transformation matrices indicates the existence of certain residual symmetry. We offer an intuitive display of the structure of the Majorana neutrino mass matrix, using the whole set of the oscillation data. The structure is revealed depending on the lightest neutrino mass. We find that there are three regions with distinct characteristics of structure. A group effect and the $\mu$-$\tau$ exchange symmetry are observed. Six types of texture non-zeros are shown. Implications for flavor models are discussed.Comment: 18 Latex pages, 8 figure

Quark-lepton complementarity and self-complementarity in different schemes

With the progress of increasingly precise measurements on the neutrino mixing angles, phenomenological relations such as quark-lepton complementarity (QLC) among mixing angles of quarks and leptons and self-complementarity (SC) among lepton mixing angles have been observed. Using the latest global fit results of the quark and lepton mixing angles in the standard Chau-Keung scheme, we calculate the mixing angles and CP-violating phases in the other eight different schemes. We check the dependence of these mixing angles on the CP-violating phases in different phase schemes. The dependence of QLC and SC relations on the CP phase in the other eight schemes is recognized and then analyzed, suggesting that measurements on CP-violating phases of the lepton sector are crucial to the explicit forms of QLC and SC in different schemes.Comment: 11 pages, 3 figures, version accepted for publication in PR

Digital RoF Aided Cooperative Distributed Antennas with FFR in Multicell Multiuser Networks

The achievable throughput of the entire cellular area is investigated, when employing fractional frequency reuse techniques in conjunction with realistically modelled imperfect optical fibre aided distributed antenna systems (DAS). Given a fixed total transmit power, a substantial improvement of the cell-edge area’s throughput can be achieved without reducing the cell-centre’s throughput. The cell-edge’s throughput supported in the worst-case direction is significantly enhanced by the cooperative linear transmit processing technique advocated. Explicitly, a cell-edge throughput of η = 5 bits/s/Hz may be maintained for a imperfect optical fibre model, regardless of the specific geographic distribution of the users

Two Rules on the Protein-Ligand Interaction

So far, we still lack a clear molecular mechanism to explain the protein-ligand interaction on the basis of electronic structure of a protein. By combining the calculation of the full electronic structure of a protein along with its hydrophobic pocket and the perturbation theory, we found out two rules on the protein-ligand interaction. One rule is the interaction only occurs between the lowest unoccupied molecular orbitals (LUMOs) of a protein and the highest occupied molecular orbital (HOMO) of its ligand, not between the HOMOs of a protein and the LUMO of its ligand. The other rule is only those residues or atoms located both on the LUMOs of a protein and in a surface pocket of a protein are activity residues or activity atoms of the protein and the corresponding pocket is the ligand binding site. These two rules are derived from the characteristics of energy levels of a protein and might be an important criterion of drug design

Strategic planning for business skills training for youth in emerging countries

The Centre of Excellence for Business Skills Development (referred to as CEBSD throughout this report) is a training centre established in 2013 as part of the project 'Strengthening Business Skills for Youth Employment in Myanmar'. This project is a collaboration between the Ministry of Education in Myanmar, UNESCO, and sponsored by PepsiCo. The project focuses on youth development and intends to equip youths in Myanmar with employability skills and leadership skills. After 6 years of implementation, this study conducts a comprehensive evaluation to identify achievements of this programme from both a quantitative and qualitative perspective. This evaluation contains reports on the training programme's sessions and the programme's operations sessions. By observing the evaluation and analysis, we can better identify the competitive advantages and disadvantages of this programme, and make any required amendments and improve the next stage of development. According to the results, we consider this programme to have reached the expected outcomes, and the students' satisfaction survey showed overall good feedback to our program, including curriculum design and faculties. For future development, apart from keeping the existing activities, more consideration should be given to the faculties' competency building and partnership development with special needs schools and organisations; business partners, and similar organisations in different areas of Myanmar.O Centro de Excelência em Habilidades Empresariais para Jovens em Mianmar é um centro de treinamento estabelecido em 2013 como parte do projeto 'Fortalecimento das Habilidades Empresariais para Emprego de Jovens em Mianmar'.

PROTEIN ENGINEERING IN THE STUDY OF PROTEIN LABELING AND DEGRADATION

Proteins are large macromolecules that play important roles in nature. With the development of modern molecular biology techniques, protein engineering has emerged as a useful tool and found many applications in areas ranging from food industry, environmental protection, to medical and life science. Biomimetic membrane incorporates biological elements, such as proteins, to form membranes that mimic the high specificity and conductance of natural biological membranes. For any application involving the usage of proteins, the first barrier is always the production of proteins with sufficient stability, and the incorporation of proteins into the artificial matrix. This thesis contains two major parts, the first part is focused on the development and testing of method to immobilize active enzymes. The second part is devoted to study the degradation of membrane proteins in E. coli cells. In the immobilization study, Pyrophosphatase (PpaC) was chose as a model enzyme. A dual functional tag consist of histidine and methionine has been developed, in which histidine is used for purification while methionine is metabolically replaced with azidohomoalanine (AHA) for immobilization. We found that the addition of the tag and the incorporation of AHA did not significantly impair the properties of proteins, and the histidine–AHA tag can facilitate protein purification, immobilization, and labeling. This tag is expected to be useful in general for many proteins. Degradation of soluble protein has been well characterized, but the membrane protein degradation process remains elusive. SsrA tag is a well-known recognition sequence for soluble protein degradation, which marks prematurely terminated protein products translated from damaged mRNA. SsrA tagged membrane proteins was found to be substrate of a cytosolic protease complex ClpXP, which mediated complete degradation
