Construction and Use Examples of Private Electronic Notary Service in Educational Institutions

People have many documents. For example, a variety of documents are prepared and used in public institutions. As the internet becomes widely available in recent years, paper documents are being replaced with electronic data, which are often distributed in the form of electronic data without being printed out. Similarly, in educational institutions, increasing number of documents are distributed in the form of electronic data. Such data are distributed through various routes and means, and prone to the risk of alteration in the process. Data may be protected against alteration, but it is difficult to completely prevent data alteration in the distribution process. Data can be generated with electronic signature that allows for the identification of data creator and possible alterations by third parties. This method is, however, not valid if the data becomes separated from the electronic signature, making the validation of data creator or data alterations difficult or impossible. In this paper, we describe the invention of a system that, even in cases where data is separated form the electronic signature, enables easy identification of possible data alterations by the electronic signature management. And we describe here an exploratory construction of private electronic notary service in university. We also add a review on the utilization method of private electronic notary service in universities

Complete set of polarization transfer coefficients for the 3He(p,n){}^{3}{\rm He}(p,n) reaction at 346 MeV and 0 degrees

We report measurements of the cross-section and a complete set of polarization transfer coefficients for the ${}^{3}{\rm He}(p,n)$ reaction at a bombarding energy $T_p$ = 346 MeV and a reaction angle $\theta_{\rm lab}$ = $0^{\circ}$. The data are compared with the corresponding free nucleon-nucleon values on the basis of the predominance of quasi-elastic scattering processes. Significant discrepancies have been observed in the polarization transfer $D_{LL}(0^{\circ})$, which are presumably the result of the three-proton $T$ = 3/2 resonance. The spin--parity of the resonance is estimated to be $1/2^-$, and the distribution is consistent with previous results obtained for the same reaction at $T_p$ = 48.8 MeV.Comment: 4 figures, Accepted for publication in Physical Review

Mutual Aid, Cooperatives, and Abolition : Reimagining Economics through, for, and of Racially Marginalized Communities

My research reimagines economics education based in the material realities of marginalized communities of color, and building upon the strategies arising from those communities to thrive and survive. Three of these strategies include mutual aid, cooperatives, and an abolitionist framework, which all emphasize marginalized groups working in solidarity to meet the needs of everyone in the community. &nbsp

Pygmy dipole resonance in 208Pb

Scattering of protons of several hundred MeV is a promising new spectroscopic tool for the study of electric dipole strength in nuclei. A case study of 208Pb shows that at very forward angles J^pi = 1- states are strongly populated via Coulomb excitation. A separation from nuclear excitation of other modes is achieved by a multipole decomposition analysis of the experimental cross sections based on theoretical angular distributions calculated within the quasiparticle-phonon model. The B(E1) transition strength distribution is extracted for excitation energies up to 9 MeV, i.e., in the region of the so-called pygmy dipole resonance (PDR). The Coulomb-nuclear interference shows sensitivity to the underlying structure of the E1 transitions, which allows for the first time an experimental extraction of the electromagnetic transition strength and the energy centroid of the PDR.Comment: submitted to Phys. Rev.

Complete electric dipole response and the neutron skin in 208Pb

A benchmark experiment on 208Pb shows that polarized proton inelastic scattering at very forward angles including 0{\deg} is a powerful tool for high-resolution studies of electric dipole (E1) and spin magnetic dipole (M1) modes in nuclei over a broad excitation energy range to test up-to-date nuclear models. The extracted E1 polarizability leads to a neutron skin thickness r_skin = 0.156+0.025-0.021 fm in 208Pb derived within a mean-field model [Phys. Rev. C 81, 051303 (2010)], thereby constraining the symmetry energy and its density dependence, relevant to the description of neutron stars.Comment: 5 pages, 5 figures, revised mansucrip

Mapping of the Genome Sequence Using Two-stage Self Organizing Maps

In this paper, we introduce an algorithm of Self-Organizing Maps(SOM) which can map the genome sequence continuously on the map. The DNA sequences are considered to have the special features depending on the regions where the sequences are taken from or the gene functions of the proteins which are translated from the sequences. If the hidden features of the DNA sequences are extracted from the DNA sequences, they can be used for predicting the regions or the functions of the sequences. In this paper, we propose the algorithms using two stage SOM which organizes the sequences of the specific length at the first stage and organizes the set of sequences at the 2nd stage This algorithm can map the genome sequences on the map at each stage depending on the features of the sequences. We made some analyses of the genome sequences concerning the functions, species and secondary structure of the sequences
