Predicting Equity Price with Corporate Action Events Using LSTM-RNN  [PDF]
Shotaro Minami
Journal of Mathematical Finance (JMF) , 2018, DOI: 10.4236/jmf.2018.81005
Abstract: Forecasting the stock price of a particular has been a difficult task for many analysts and researchers. In fact, investors are highly interested in the research area of stock price prediction. However, to improve the accuracy of forecasting a single stock price is a really challenging task; therefore in this paper, I propose a sequential learning model for prediction of a single stock price with corporate action event information and Macro-Economic indices using LTSM-RNN method. The results show that the proposed model is expected to be a promising method in the stock price prediction of a single stock with variables like corporate action and corporate publishing.
Treatment Options in Smoking Cessation: What Place for Bupropion Sustained-Release?
Danielle E McCarthy,Douglas E Jorenby,Haruka Minami,Vivian Yeh
Clinical Medicine : Therapeutics , 2009,
Abstract: Bupropion SR is approved for the treatment of tobacco dependence in adult smokers. Bupropion SR is an atypical antidepressant that has been shown to double the likelihood of quitting smoking (to roughly 19%-24% six months into a quit attempt), perhaps by acting on dopaminergic and noradrenergic systems and by acting as an antagonist of nicotine acetylcholine receptors. Head-to-head comparisons of bupropion SR and other stop-smoking treatments suggest that bupropion SR is as or more efficacious than nicotine replacement therapies, equally efficacious as nortriptyline, and less efficacious than varenicline. The evidence available regarding the effectiveness of bupropion SR in real-world settings suggests that abstinence rates are similar to those seen in controlled clinical trials. Bupropion SR appears to be safe and efficacious for both men and women and for people with comorbid medical or mental health conditions. Evidence collected to date supports the use of bupropion SR as a safe, tolerable pharmacotherapy for smoking cessation among adult smokers without a predisposition to seizures, but also suggests that benefits in terms of abstinence last only as long as treatment continues. This review focuses on recent evidence regarding bupropion SR effects and highlights important questions regarding the duration of effects, relative efficacy, effectiveness in clinical use, mechanisms of action, and utilization of bupropion SR that remain unanswered.
Comparative Investigation of Alternative Negative Staining Reagents in Bacterial Morphological Study  [PDF]
Masaaki Minami, Hiroshi Takase
Journal of Biosciences and Medicines (JBM) , 2017, DOI: 10.4236/jbm.2017.510002
Abstract: Negative staining is an effective method that can be used for electron microscopic study to observe fine structural morphology without destruction of bacterial structure. Although uranium acetate is used worldwide as a general dyeing solution, it is extremely difficult to use it by a new purchase at a research institution because it falls under the nuclear regulation substance in Japan. Therefore, we examined alternative reagents for negative staining that could replace uranium acetate through bacterial observation with an electron microscope. Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pyogenes were examined by four stain reagents (phosphotungstic acid (PTA), EMstainer, TI blue, and uranium acetate). Pre cultured bacteria were stained with each stain reagents on a copper grid, washed with PBS, and observed with a transmission electron microscope. In the comparison between bacterial structures, the cell wall structure and bacterial flagella could be observed well in the order of PTA, EMstainer, and uranium acetate. With TI blue staining, flagella could be observed very poorly. In comparison between bacteria, gram negative bacteria such as Escherichia coli and Pseudomonas aeruginosa, could be observed well as compared with gram positive cocci such as Staphylococcus aureus and Streptococcus pyogenes. The uranium acetate looked very coarse in background particles. Since crystals tend to precipitate, TI blue also required filtering, and electron beams were absorbed by the agglomerated crystals, and the frequency of electronic burning occurred high frequency. In this study, there was clear difference in the observation conditions depending on the type of bacteria and the kind of the staining reagents. Especially, it was confirmed that good negative staining features of Pseudomonas aeruginosa by electron microscope were obtained by PTA and EMstainer staining. These alternative reagents are considered to be a candidate for a negative staining.
Fundamental Factor Models Using Machine Learning  [PDF]
Seisuke Sugitomo, Shotaro Minami
Journal of Mathematical Finance (JMF) , 2018, DOI: 10.4236/jmf.2018.81009
Abstract: Fundamental factor models are one of the important methods for the quantitative active investors (Quants), so many investors and researchers use fundamental factor models in their work. But often we come up against the problem that highly effective factors do not aid in our portfolio performance. We think one of the reasons that why the traditional method is based on multiple linear regression. Therefore, in this paper, we tried to apply our machine learning methods to fundamental factor models as the return model. The results show that applying machine learning methods yields good portfolio performance and effectiveness more than the traditional methods.
Ionic Liquids in Tribology
Ichiro Minami
Molecules , 2009, DOI: 10.3390/molecules14062286
Abstract: Current research on room-temperature ionic liquids as lubricants is described. Ionic liquids possess excellent properties such as non-volatility, non-flammability, and thermo-oxidative stability. The potential use of ionic liquids as lubricants was first proposed in 2001 and approximately 70 articles pertaining to fundamental research on ionic liquids have been published through May 2009. A large majority of the cations examined in this area are derived from 1,3-dialkylimidazolium, with a higher alkyl group on the imidazolium cation being beneficial for good lubrication, while it reduces the thermo-oxidative stability. Hydrophobic anions provide both good lubricity and significant thermo-oxidative stability. The anions decompose through a tribochemical reaction to generate metal fluoride on the rubbed surface. Additive technology to improve lubricity is also explained. An introduction to tribology as an interdisciplinary field of lubrication is also provided.

Fractal structure of a solvable lattice model
Kazuhiko Minami
Physics , 2007,
Abstract: Fractal structure of the six-vertex model is introduced with the use of the IFS (Iterated Function Systems). The fractal dimension satisfies an equation written by the free energy of the six-vertex model. It is pointed out that the transfer matrix method and the $n$-equivalence relation introduced in lattice theories have also been introduced in the area of fractal geometry. All the results can be generalized for the models suitable to the transfer matrix treatment, and hence this gives general relation between solvable lattice models and fractal geometry.
Dynamics near QCD critical point by dynamic renormalization group
Yuki Minami
Physics , 2011, DOI: 10.1103/PhysRevD.83.094019
Abstract: We work out the basic analysis of dynamics near QCD critical point (CP) by dynamic renormalization group (RG). In addition to the RG analysis by coarse graining, we construct the nonlinear Langevin equation as a basic equation for the critical dynamics. Our construction is based on the generalized Langevin theory and the relativistic hydrodynamics. Applying the dynamic RG to the constructed equation, we derive the RG equation for the transport coefficients and analyze their critical behaviors. We find that the resulting RG equation turns out to be the same as that for the liquid-gas CP except for an insignificant constant. Therefore, the bulk viscosity and the thermal conductivity strongly diverge at the QCD CP. We also show that the thermal and viscous diffusion modes exhibit critical slowing down with the dynamic critical exponents $z_{\rm thermal}\sim 3$ and $z_{\rm viscous}\sim 2$, respectively. In contrast, the sound propagating mode shows critical speeding up with the negative exponent $z_{\rm sound}\sim -0.8$.

The free energies of six-vertex models and the n-equivalence relation
Kazuhiko Minami
Physics , 2006,
Abstract: The free energies of six-vertex models on general domain D with various boundary conditions are investigated with the use of the n-equivalence relation which classifies the thermodynamic limit properties. It is derived that the free energy of the six-vertex model on the rectangle is unique in the limit in which both the height and the width goes to infinity. It is derived that the free energies of the model on D are classified through the densities of left/down arrows on the boundary. Specifically the free energy is identical to that obtained by Lieb and Sutherland with the cyclic boundary condition when the densities are both equal to 1/2. This fact explains several results already obtained through the transfer matrix calculations. The relation to the domino tiling (or dimer, or matching) problems is also noted.
