Encoding of high-frequency order information and prediction of short-term stock price by deep learning (2019)

Predicting the price trends of stocks based on deep learning and high-frequency data has been studied intensively in recent years. Especially, the limit order book which describes supply-demand balance of a market is used as the feature of a neural network; however these methods do not utilize the properties of market orders. On the other hand, the order-encoding method of our prior work can take advantage of these properties. In this paper, we apply some types of convolutional neural network architectures to order-based features to predict the direction of mid-price trends. The results show that smoothing filters which we propose to employ rather than embedding features of orders improve accuracy. Furthermore, inspection of the embedding layer and investment simulation are conducted to demonstrate the practicality and effectiveness of our model.

Patient dosimetry for hybrid MRI‐radiotherapy systems (2008)

A novel geometry has been proposed for a hybrid magnetic resonance imaging (MRI)-linac system in which a 6 MV linac is mounted on the open end of a biplanar, low field (0.2 T) MRI magnet on a single gantry that is free to rotate around the patient. This geometry creates a scenario in which the magnetic field vector remains fixed with respect to the incident photon beam, but moves with respect to the patient as the gantry rotates. Other proposed geometries are characterized by a radiation source rotating about a fixed cylindrical magnet where the magnetic field vector remains fixed with respect to the patient. In this investigation we simulate the inherent dose distribution patterns within the two MRI-radiation source geometries using PENELOPE and EGSnrc Monte Carlo radiation transport codes with algorithms implemented to account for the magnetic field deflection of charged particles. Simulations are performed in phantoms and for clinically realistic situations. The novel geometry results in a net Lorentz force that remains fixed with respect to the patient (in the cranial-caudal direction) and results in a cumulative influence on dose distribution for a multiple beam treatment scenario. For a case where patient anatomy is reasonably homogeneous (brain plan), differences in dose compared to a conventional (no magnetic field) case are minimal for the novel geometry. In the case of a lung plan where the inhomogeneous patient anatomy allows for the magnetic field to have significant influence on charged particle transport, larger differences occur in a predictable manner. For a system using a fixed cylindrical geometry and higher magnetic field (1.5 T), differences from the case without a magnetic field are significantly greater.
Structural and Electrochemical Characterization of Nanocrystalline Li[Li<sub>0.12</sub>Ni<sub>0.32</sub>Mn<sub>0.56</sub>]O<sub>2</sub> Synthesized by a Polymer-Pyrolysis Route (2005)

A nanocrystalline Li[Li0.12Ni0.32Mn0.56]O2 powder was synthesized via the pyrolysis of polyacrylate salt precursors prepared by in situ polymerization of the metal salts and acrylate acid. The pyrolysis mechanism of the polymeric precursor is discussed by use of thermal analysis. Layered crystalline structure of the resulting compound was characterized by powder X-ray diffraction and high-resolution transmission electron (TEM) micrographs. The results revealed that the Li[Li0.12Ni0.32Mn0.56]O2 as prepared has nanosized morphology and good crystallinity even if calcined at 900 °C, and the electrodes made from these nanoparticles exhibited high-rate characteristics and can deliver stable discharge capacity (163 mA·h/g) with excellent capacity retention at appropriate charge−discharge voltage interval. Since this preparation method is simple and particularly suitable for preparation of mixed metal oxides, it can be used for industrial production of highly homogeneous metal oxide cathode materials of the lithium-ion batteries.
Linolenic Acid-Modified Chitosan for Formation of Self-Assembled Nanoparticles (2004)

Chitosan was modified by coupling with linolenic acid through the 1-ethyl-3-(3-dimethylaminopropyyl)carbodiimide-mediated reaction. The degree of substitution was measured by 1H NMR, and it was 1.8%, i.e., 1.8 linolenic acids group per 100 anhydroglucose units. The critical aggregation concentration (CAC) of the self-aggregate of hydrophobically modified chitosan was determined by measuring the fluorescence intensity of the pyrene as a fluorescent probe. The CAC value in phosphate-buffered saline (PBS) solution (pH 7.4) was 5 x 10(-2) mg/mL. The average particle size of self-aggregates of hydrophobically modified chitosan in PBS solution (pH 7.4) was 210.8 nm with a unimodal size distribution ranging from 100 to 500 nm. A transmission electron microscopy study showed that the formation of near spherical shape nanoparticles had enough structural integrity. The loading ability of hydrophobically modified chitosan (LA-chitosan) was investigated by using bovine serum albumin (BSA) as a model protein. Self-aggregated nanoparticles exhibited an increased loading capacity (19.85 +/- 0.04 to 37.57 +/- 0.25%) with an increasing concentration of BSA (0.1-0.5 mg/mL).
Chapter News (2011)

Decently, I had the privilege of attending the 2011 IEEE Sections Congress (SC20ll), held in San Francisco, thanks to the kind invitation by Prof. Magdalena Salazar-Palma, President of IEEE AP-S. The IEEE Sections Congress is held once every three years, and is a big gathering for IEEE volunteers worldwide. It was an eye-opening experience for me, and I learned a lot from many talks I attended. In addition to keynote addresses and general sessions, there were more than 80 breakout sessions, where speakers shared information on specific topics with attendees.
Serum testosterone levels in post-traumatic stress disorder inpatients (1990)

In a longitudinal clinical psychoendocrine study, serum testosterone levels (ng/dl) were measured at 2-week intervals during the course of hospitalization in 34 male psychiatric inpatients in four diagnostic groups, including post-traumatic stress disorder (PTSD), major depressive disorder (endogenous type) (MDD-E), paranoid schizophrenia (PS), and bipolar I disorder- manic (BP), as well as in a group of normal male control subjects (CONT). A one-way analysis of variance revealed that the mean (± SE) testosterone levels were significantly higher (p<0.0002) in the PTSD (578±59), PS (571±49), and CONT (494±24) groups than in the MDD-E (331±47) and BP (351±31) groups. The same group differences were significant in the first sample (p<0.02), while in the last sample the values were significantly higher (p<0.0004) in the PTSD (623±66) and PS (566±72) groups than in the CONT (482±26), BP (353±61), and MDD-E (291±52) groups. These preliminary findings, then, indicate that in spite of considerable depressive symptomatology, PTSD patients do not show the relatively low testosterone levels seen in major depressive disorder patients, but instead align more closely with the schizophrenic patients with regard to the pituitary-gonadal system. There is also an indication that chronic basal testosterone levels in PTSD patients may be elevated in comparison with normal subjects. The possible link suggested by the psychoendocrine literature between testosterone levels and trait factors, particularly paranoid style, in these patient groups is considered, as is the potential application of these findings for multidimensional approaches to the development of improved biologic criteria for psychiatric diagnosis.
Test procedure for artificial mitral valves (1998)

The flow curve of a valve-tester has a great influence on the performance of a valve. Usually the flow curve of the aorta is used. However, the mitral valve flow curve differs greatly from the flow curve of the aortic valve. It varies with the pulse rate and is further changed in patients with certain heart diseases. To investigate the different mitral flow conditions, ultrasonic flow curves from patients with a mechanical artificial mitral valve were analyzed. The curves show that a mitral valve prosthesis has not only to work under physiological flow conditions, but also in pathologically deviant flows. According to these results three different characteristic flow curves were selected and used to test several valves with a computer controlled valve-tester. The mean diastolic pressure difference and the whole closing behavior were influenced by the flow curve; and the differences in energy losses were particularly great. This indicates, that the flow curve must be adjusted appropriately. (Int J Artif Organs 1998; 21:37–42)
Identification of mutations in seven Chinese patients with X-linked chronic granulomatous disease (1996)

X-linked chronic granulomatous disease (CGD) is due to mutations in the gp91phox gene on Xp21.1. Studies in white and Japanese X-linked CGD patients have shown mutations in nearly every exon. We studied the molecular defect of seven Chinese patients with X-linked CGD from six unrelated families. Mutations were located by single-strand conformation polymorphism and then defined by sequence analysis. The mutations were two different amino acid substitutions, a nonsense mutation, an in-frame trinucleotide deletion, a single A insertion causing a frameshift, and a premature stop. Lastly, a rare splice site mutation caused by G to A transition at the terminal nucleotide of exon 3, resulting in the skipping of exon 3, was found. The possible effects of these mutations on protein structure-function or splicing were discussed. Together with previous reports, the A insertion in the run of six As from nucleotide 749 to 754 and the G to A transition at the terminal position of exon 3 may be mutation hotspots of the gp91phox gene. The extreme heterogeneous mutations found in our patients suggest the absence of ethnic group-specific mutation.
Apparatus for studying fretting fatique in vacuum (1979)

Recent investigations on the mechanism of fretting fatigue have indicated that mechanical damage, not chemical corrosion, has the largest effect in decreasing structural component life. Since there is no general agreement on the mechanism of fretting fatigue, an experiment has been designed to evaluate statistically the relative role of the mechanical process and the chemical process in reducing fatigue life. An initial step was to develop an apparatus that allows fretting fatigue tests to be performed in both laboratory air and vacuum environments. A detailed discussion of the experimental apparatus and experimental procedure are presented in this paper. Also typical test results are presented. It is found that fretting fatigue in vacuum is about ten times slower than that in laboratory air. Fractographic analysis of the wear surface indicated that less severe fretting damage occurred in the vacuum environment.

Coexpression of estrogen receptor alpha and beta: poor prognostic factors in human breast cancer? (1999)

The cloning of a second estrogen receptor (ER), ER beta, has prompted a reevaluation of the role of ERs in breast cancer. The aim of this study was to determine the expression of both ER isoforms in normal (n = 23) and malignant (n = 60) human breast tissue by reverse transcription-PCR and correlate this information with known prognostic factors including tumor grade and node status. In normal breast tissue, expression of ER beta predominated, with 22% of samples exclusively expressing ER beta; this was not observed in any of the breast tumor samples investigated. Most breast tumors expressed ER alpha, either alone or in combination with ER beta. Interestingly, those tumors that coexpressed ER alpha and ER beta were node positive (P = 0.02; Fisher's exact test) and tended to be of higher grade. Because antiestrogens are agonists when signaling through the AP1 element, overexpression of ER beta in tumors expressing both ER subtypes may explain the failure of antiestrogen therapy in some breast cancer patients. Thus, ER beta may be a useful prognostic factor in patients with breast cancer.

Enhanced Magnetism in Highly Ordered Magnetite Nanoparticle‐Filled Nanohole Arrays (2014)

A new approach to develop highly ordered magnetite (Fe3O4) nanoparticle-patterned nanohole arrays with desirable magnetic properties for a variety of technological applications is presented. In this work, the sub-100 nm nanohole arrays are successfully fabricated from a pre-ceramic polymer mold using spin-on nanoprinting (SNAP). These nanoholes a then filled with monodispersed, spherical Fe3O4 nanoparticles of about 10 nm diameter using a novel magnetic drag and drop procedure. The nanohole arrays filled with magnetic nanoparticles a imaged using magnetic force microscopy (MFM). Magnetometry and MFM measurements reveal room temperature ferromagnetism in the Fe3O4-filled nanohole arrays, while the as-synthesized Fe3O4 nanoparticles exhibit superparamagnetic behavior. As revealed by MFM measurements, the enhanced magnetism in the Fe3O4-filled nanohole arrays originates mainly from the enhanced magnetic dipole interactions of Fe3 O4 nanoparticles within the nanoholes and between adjacent nanoholes. Nanoparticle filled nanohole arrays can be highly beneficial in magnetic data storage and other applications such as microwave devices and biosensor arrays that require tunable and anisotropic magnetic properties.
Temperature differences are associated with malignancy on lung lesions: a clinical study (2003)

von Willebrand factor cleaving protease (ADAMTS‐13) and ADAMTS‐13 neutralizing autoantibodies in 100 patients with thrombotic thrombocytopenic purpura (2004)

The congenital or acquired deficiency of the von Willebrand factor (VWF) cleaving protease, ADAMTS-13 has been specifically associated with a diagnosis of thrombotic thrombocytopenic purpura (TTP), a microangiopathy characterized by the formation of occlusive platelet thrombi. The mechanisms of TTP were investigated in 100 patients diagnosed on the basis of the presence of at least three of the following: thrombocytopenia, haemolytic anaemia, elevated serum levels of lactate dehydrogenase and neurological symptoms. Plasma levels of ADAMTS-13 were severely reduced (<10% of normal) in 48%, moderately reduced (between 10% and 46%) in 24% and normal (>46%) in 28%. A neutralizing antibody was the cause of the deficiency in 38% of the cases, with a higher prevalence of this mechanism (87%) in the 48 patients with severely reduced ADAMTS-13. Double heterozygosity for a 29 base pair (bp) deletion and a nucleotide insertion and homozygosity for a 6 bp deletion in the ADAMTS13 gene were identified only in two patients born from consanguineous marriages. In conclusion, this study indicated that ADAMTS-13 was normal in nearly one-third of patients with TTP and that ADAMTS-13 deficiency was not associated with the presence of neutralizing antibodies in more than half of the patients.
Structural changes of cellulose dissolved in molten salt hydrates (2000)

The behavior of cellulose in molten salt hydrates, e. g., LiClO4*3 H2O, ZnCl2*4 H2O, LiCl*5 H2O and mixtures of thiocyanates was investigated. Melts, which give rise to a swelling or dissolution of the cellulose were the focus of interest. The melt composition and species, the water amount and the structure of the coordination sphere of the cation of the molten salt hydrate as well as the acidity influence the solubility of the cellulose in molten salt systems. The interactions between cellulose and species of the melts were determined by solution state 13C NMR measurements at temperatures between 65°C and 140°C. Each regenerated cellulose showed other but specific properties which were characterized by wide angle X-ray Scattering (WAXS), solid-state NMR (13C CP/MAS NMR), molecular weight distribution, surface-area determinations and scanning electron microscopy (SEM).
The effects of gate field on the leakage characteristics of heavily doped junctions (1989)

A gated-diode leakage-current mechanism is reported that is dominant below 4 V in ULSI (ultra-large-scale integration) gated-diode structures. The leakage mechanism has been fully characterized for gated junctions inherent in DRAM (dynamic random access memory) storage capacitor structures and the source-drain junctions of both PMOS (p-metal-oxide-semiconductor) and NMOS device structures. The salient features of the observed leakage current are that it is thermally activated and its magnitude increases exponentially with applied gate voltage. By making measurements at cryogenic temperatures it was possible to distinguish between the reported mechanism and that of band-to-band tunneling that occurs at higher applied voltages. A theoretical model is proposed that attributes the leakage mechanism to transport-limited thermal generation within the depleted space-charge region of the heavily doped side of junctions. An analytical expression derived from the proposed model is shown to be in excellent agreement with experimental results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Random forests for resource allocation in 5G cloud radio access networks based on position information (2018)

Next generation 5G cellular networks are envisioned to accommodate an unprecedented massive amount of Internet of things (IoT) and user devices while providing high aggregate multi-user sum rates and low latencies. To this end, cloud radio access networks (CRAN), which operate at short radio frames and coordinate dense sets of spatially distributed radio heads, have been proposed. However, coordination of spatially and temporally denser resources for larger sets of user population implies considerable resource allocation complexity and significant system signalling overhead when associated with channel state information (CSI)-based resource allocation (RA) schemes. In this paper, we propose a novel solution that utilizes random forests as supervised machine learning approach to determine the resource allocation in multi-antenna CRAN systems based primarily on the position information of user terminals. Our simulation studies show that the proposed learning based RA scheme performs comparably to a CSI-based scheme in terms of spectral efficiency and is a promising approach to master the complexity in future cellular networks. When taking the system overhead into account, the proposed learning-based RA scheme, which utilizes position information, outperforms legacy CSI-based scheme by up to 100%. The most important factor influencing the performance of the proposed learning-based RA scheme is antenna orientation randomness and position inaccuracies. While the proposed random forests scheme is robust against position inaccuracies and changes in the propagation scenario, we complement our scheme with three approaches that restore most of the original performance when facing random antenna orientations of the user terminal.
Quantitative Measurement of Tetrahydromenaquinone-9 in Cheese Fermented by Propionibacteria (2007)

Propionibacteria produce tetrahydromenaquinone-9 [MK-9 (4H)] as a major menaquinone (vitamin K2). This study aimed to determine the MK-9 (4H) concentration in commercial propionibacteria-fermented cheese. The MK-9 (4H) concentration was quantified using an HPLC instrument with a fluorescence detector after postcolumn reduction. Among the various cheese samples, the MK-9 (4H) concentration was highest in Norwegian Jarlsberg cheese, followed by Swiss Emmental cheese. In contrast, the MK-9 (4H) concentrations in Appenzeller or Gruyère cheeses were extremely low or undetected. Likewise, the concentrations in Comte and Raclette cheeses were lower than those in Jarlsberg and Emmental cheeses. In the present study, the MK- 9 (4H) concentration in cheese showed a correlation with the viable propionibacterial cell count and propionate concentration. This implies that the increase in propionibacteria contributed to the generation of MK-9 (4H) in cheese. We presumed, based on these results, that Swiss Emmental and Norwegian Jarlsberg cheeses contain a meaningful amount of vitamin K because of their high MK-9 (4H) concentrations (200 to 650 ng/g).
The Oxo Reaction of Unconjugated α, ω-Diolefin (1964)

Performance analysis for ad hoc QoS routing protocols (2002)

One of the major challenges faced by designers of ad hoc network systems is the deployment of end-to-end quality-of-service support mechanisms. The paper presents a comprehensive performance analysis and comparison of two QoS-enhanced ad hoc network protocols. We assume that the underlying network uses a time slotted data link layer such as TDMA. We developed integrated, QoS-aware versions of AODV (ad-hoc on-demand distance vector) and TORA (temporally ordered routing algorithm), two well-known ad hoc routing protocols. Using the ns-2 simulator, we have conducted an extensive set of performance experiments for these protocols with a wide variety of mobility patterns and reservation strategies. Our experiments show that by using the relatively minor modifications we suggest, both routing methods can significantly improve the probability of being able to find an end-to-end QoS path.
