Anomaly Detection based on Doubly-Kernelized Scoring and Matrix Kernels (2016)

We consider the task of simultaneous anomaly detection in a system and its elements by comparing a pair of multivariate data sets. This task corresponds to simultaneously conducting anomaly detection and localization. For solving this task, we estimate scores which represent anomalousness of a whole system and its elements. This scoring is difficult for the following reasons. First, it is not trivial how to estimate the scores by taking into account changes of relationships between the elements, which strongly correlate with each other. Second, it is required that scores of the system and its elements are estimated from a single framework. Otherwise, the relation between the scores is not clear and thus localization becomes difficult. We propose a solution, which is a single framework to simultaneously estimate anomalousness of a system and its elements. The key ideas of the method are the following two. First, we introduce doubly kernelized scores. We construct a score by using difference between kernel matrices defined between elements. Then we represent the difference by using a kernel defined between matrices. Second, we construct matrix kernels, which are defined between different dimensional matrices. This method has the following properties: (1) the method can be applied to any data sets where a kernel can be defined between the elements, (2)can estimate scores of element group of any number, and (3)can be applied to a pair of data sets whose numbers of elements are different. Especially, the second and the third properties are realized by introducing matrix kernels. We demonstrate the effectiveness of the proposed method through the experimental results using three data sets.

Selective Lanthanides Sequestration Based on a Self‐Assembled Organosilica (2010)

In this paper, we investigate the cation-exchange properties of a self-assembled hybrid material towards trivalent ions, lanthanides (La(3+), Eu(3+), Gd(3+), Yb(3+)) and Fe(3+). The bis-zwitterionic lamellar material was prepared by sol-gel process from only 3-aminopropyltriethoxysilane (APTES), succinic anhydride, and ethylenediamine. In ethanol heated under reflux, the exchange ethylenediammonium versus Ln(3+) proved to be complete by complexometry measurements and elemental analyses, one Cl(-) ion per one Ln(III) remaining as expected for charge balance. In aqueous solution at 20 degrees C, the material was found to be selective towards lanthanide in spite of the similarity of their ionic radii. The cation uptake depends on the nature of the salt, the difference between two lanthanides reaching up to 20 % in some cases. Finally, ion-exchange reaction with FeCl(3) was chosen as a probe to get more information on the material after incorporation of trivalent ions. Based on Mössbauer spectroscopic investigations on the resulting material in conjunction with the XRD analysis of materials containing trivalent ions, a structural model was proposed to describe the incorporation of trivalent ions by exchange reaction within the original zwitterionic material.
Distributed Degenerate Band Edge Oscillator (2020)

We propose a new class of oscillators by engineering the dispersion of two-coupled periodic waveguides to exhibit a degenerate band edge (DBE). The DBE is an exceptional point of degeneracy (EPD) of order four, i.e., representing the coalescence of four eigenmodes of a waveguide system without loss and gain. We present a distributed DBE oscillator realized in periodic coupled transmission lines with a unique mode selection scheme that leads to a stable single-frequency oscillation, even in the presence of load variation. The DBE oscillator potentially leads to a boost of the efficiency and performance of radio frequency (RF) sources, due to the unique features associated with the EPD concept. This class of oscillators is promising for improving discrete-distributed coherent sources and can be extended to radiating structures to achieve a new class of active integrated antenna arrays.

Selective serotonin 5-HT1A receptor biased agonists elicitdistinct brain activation patterns: a pharmacoMRI study (2016)

Serotonin 1A (5-HT1A) receptors are involved in several physiological and pathological processes and constitute therefore an important therapeutic target. The recent pharmacological concept of biased agonism asserts that highly selective agonists can preferentially direct receptor signaling to specific intracellular responses, opening the possibility of drugs targeting a receptor subtype in specific brain regions. The present study brings additional support to this concept thanks to functional magnetic resonance imaging (7 Tesla-fMRI) in anaesthetized rats. Three 5-HT1A receptor agonists (8-OH-DPAT, F13714 and F15599) and one 5-HT1A receptor antagonist (MPPF) were compared in terms of influence on the brain blood oxygen level-dependent (BOLD) signal. Our study revealed for the first time contrasting BOLD signal patterns of biased agonists in comparison to a classical agonist and a silent antagonist. By providing functional information on the influence of pharmacological activation of 5-HT1A receptors in specific brain regions, this neuroimaging approach, translatable to the clinic, promises to be useful in exploring the new concept of biased agonism in neuropsychopharmacology.
Primary Reninism: Hypertension, Hyperreninaemia and Secondary Aldosteronism Due to Juxtaglomerular Renal Cell Tumours (1973)

1. A further case of renin-secreting renal juxtaglomerular cell tumour is reported. 2. Hypertension, aldosteronism and hypokalaemia were associated with high peripheral levels of renin. 3. Renin activity was twice as high in right as in left renal vein plasma. 4. A renal juxtaglomerular cell tumour was found in the right kidney and removed, after which the biochemical abnormalities and blood pressure were promptly corrected. 5. Explants of tumour tissue in culture produced large amounts of renin.
Acoustic modulators for optical fibres (1985)

We have examined techniques for acoustic modulation of an optical fibre. A simple coupled mode theory has been developed which shows that by use of an acoustic wave propagating in the direction of the fibre, it is possible to make a single-sideband modulator. Experimental results confirming these ideas are given, along with some ideas for future direction of this work.
Risk analysis for intraoperative liver surgery (2010)

Hepatic vessel structure is very important to ensure the blood supply of the liver tissue. Therefore the knowledge of the hepatic vessel system is indispensable in liver surgery planning, for example before performing a liver resection. The purpose of this paper is to present an easy to use and fast method concerning hepatic vessel segmentation and risk analysis, which is intended to be applicable in clinical routine.
A Preparation of the Ethylene Glycol Mono-Ketal of Cyclohexane-1,4-Dione (1975)

Abstract A recently published paper1 reporting a new synthetic route to the ethylene glycol mono-ketal of cyclohexane-1,4-dione promted us to publish the results obtained in our laboratory. In fact we have developed a different synthesis of (2), starting from cyclohexane-1,4-diol (1), with overall yields higher than those reported in the above mentioned paper and without employment of any anhydrous solvent.
A Microscale Quadrupole Mass Spectrometer for Ion Species Analysis (2004)

Investigators have identified a quadrupole structure that uses non-traditional geometry with rectangular cantilevered electrodes and that is amenable to semiconductor fabrication. Despite the revolutiotiary electrode geometry, the proposed microscale quadrupole mass filter displays a sizeable internal volume within which the field is equivalent to that of a conventional quadrupole mass filter with circular electrodes. Numerical analyses predict that the mass resolution and transmission efficiency are nearly identical with those of an equivalent cylindrical device. Batch processing techniques could be employed to produce massively parallel arrays of microscale quadrupole filters in a cost-effective manner. Prototype filters were fabricated using conventional semi-conductor manipulation protocols in conjunction with molecular beam epitaxy on GaAs/AlGaAs. The preliminary electric characterization of the prototype indicates broad mass range up to 1,500 amu with minimal power requirements. Such a micro device would be invaluable for light species analysis in numerous applications including plasma diagnostics, residual gas analysis, detection of chemical and products of biological agents, and integrated sensing of gas quality in medical and pharmaceutical applications. © 2004 by Lyon B.

Demonstration of a single-wavelength spectral-imaging-based Thai jasmine rice identification (2011)

A single-wavelength spectral-imaging-based Thai jasmine rice breed identification is demonstrated. Our nondestructive identification approach relies on a combination of fluorescent imaging and simple image processing techniques. Especially, we apply simple image thresholding, blob filtering, and image subtracting processes to either a 545 or a 575 nm image in order to identify our desired Thai jasmine rice breed from others. Other key advantages include no waste product and fast identification time. In our demonstration, UVC light is used as our exciting light, a liquid crystal tunable optical filter is used as our wavelength seclector, and a digital camera with 640 active pixels × 480 active pixels is used to capture the desired spectral image. Eight Thai rice breeds having similar size and shape are tested. Our experimental proof of concept shows that by suitably applying image thresholding, blob filtering, and image subtracting processes to the selected fluorescent image, the Thai jasmine rice breed can be identified with measured false acceptance rates of <22.9% and <25.7% for spectral images at 545 and 575 nm wavelengths, respectively. A measured fast identification time is 25 ms, showing high potential for real-time applications.
Carcinogen-DNA and protein adducts: Biomarkers for cohort selection and modifiable endpoints in chemoprevention trials (1996)

Chemical-specific markers have been developed for a number of environmental carcinogens for use as molecular dosimeters of individual exposure. In addition to contributing substantially to the specificity and sensitivity of epidemiological studies aimed at determining the role of environmental agents in the etiology of human cancers, some of these biomarkers may prove to be useful endpoints for assessing the efficacy of preventive interventions including exposure avoidance or remediation and chemoprevention. Biomarkers of the biologically effective dose may be particularly useful in this context in that they provide a mechanistic linkage between exposure and disease outcome. The biologically effective dose reflects the amount of toxicant that has interacted with its critical molecular target and can be measured through a variety of analytical techniques as either carcinogen-DNA or -protein adducts. Approaches for the development and validation of aflatoxin adduct biomarkers are presented as a paradigm for the application of carcinogen-specific markers for cohort selection and as modifiable endpoints for assessing efficacy in chemoprevention trials.
Effect of Heat Treatmemt in (α+γ) Range on Mechanical Properties of Austempered Spheroidal Graphite Cast Iron (2018)

It is well known that austempered spheroidal graphite cast iron shows good tensile and elongation. And, retained austenite include in the austempered spheroidal graphite cast iron structure was known to effect for the mechanical properties when TRIP was occurred. On the other hand, fineness and homogeneity of the structure are considered to influence as a factor to improve mechanical property. In this study, the mechanical properties of spherical graphite cast iron was evaluated that it treatmented fineness prior-structure and austenitized at (α + γ) range followed by isothermal treatment at bainitic transformation temperature range. Compared the heat treatment of this study and typical austempering treatment, the mechanical properties with good balance of strength and ductility were obtained in the heat treatment of this study. But, retained austenite that it determined by x-ray diffraction was slightly changed before and after the tensile test. Therfore, it was considered that not TRIP but complex phase effect on mechanical properties.
Using Cadaver Specimens to Better Understand Ulnar Nerve to Median Nerve Transfers (2018)

The recurrent branch of the median nerve innervates the thenar muscles. Therefore, injury to the median nerve as it courses from the axilla to the hand has profound negative effects on the functional use of the thumb. The surgical procedure of peripheral nerve transplants in order to regain function in denervated muscle is well documented. Using the lumbrical branch of the ulnar nerve to the 4 th digit as a nerve transplant with the recurrent branch of the median nerve in order to regain function is not well documented. As such, the capacity of grafting these ulnar nerve branches from their anatomical position including neuron count of each nerve and their ability to be spliced together was investigated. Cadaveric dissections were performed to document the distribution of the deep branch of the ulnar nerve as it enters the lumbrical musculature and the recurrent branch of the median nerve as it courses through the carpal tunnel. After the dissection was completed, the ulnar branch to the lumbrical muscle was drawn towards the recurrent branch of the median nerve. Using a digital camera, and electronic calipers the nerves were photographed for visual confirmation of the ability to transfer and measured to compare the size of the nerves. Sections of each branch were then studied for a comparison of neuron counts. Data suggests the nerve transfer to be a viable option, and could assist neurosurgeons in performing surgeries to help patients regain functionality in their thenar muscles. A continuation of data collection will allow greater insight into the number of neurons that can potentially re‐innervate the thenar muscles as well as assist in desired surgical outcomes.

Reduction of crosstalk and losses of intersecting waveguide (1989)

Experimental results of crosstalk and losses of intersecting Ti: LiNbO3 waveguides are presented. To achieve lower losses and crosstalk the waveguides are tapered in the crossing area. While maintaining crosstalk of — 30 dB the 6° intersection angle of a conventional intersection can be reduced to 4° by using a 25 µm-wide taper.
A Computer-Assisted Approach to Assess the Precision of the Reciprocating Angles and the Rotation Speeds of Endodontic Motors (2022)

Endodontic reciprocating motors are largely used to support a series of procedures in dentistry treatments, useful for those different circular movement patterns. In the last years, different motors have been available on the market, with varying costs and promised performance for the users; however, since their reciprocating angles and rotation speeds may have significant outcomes on the employed endodontic files, there should be an affordable and practical way to assess the actual performance of such motors concerning their expected operation. Actually, endodontic files attached to reciprocating motors will move too fast to be easily accounted, which has fostered the development of computational methods to allow the proper validation of their movements according to their official datasheets. In this scenario, this paper describes a feasible method to detect the movement patterns of different reciprocating endodontic motors by the processing of a set of consecutive images taken by a high-speed camera. The performed experiments for three different off-the-shelf reciprocating endodontic motors showed that their actual movement characteristics are slightly different from their specifications, and that each considered motor has a particular movement pattern.
Selective Radiofrequency Catheter Ablation of the Slow Pathway for Common and Uncommon Atrioventricular Nodal Reentrant Tachycardia. (1996)

The utility of selective radiofrequency catheter ablation of the slow pathway for the treatment of common and uncommon atrioventricular nodal reentrant tachycardia (AVNRT) was studied in 110 consecutive patients, 94 with slow-fast form common AVNRT, and 11 and 5, respectively, with the fast-slow and slow-slow forms of uncommon AVNRT. Ablation sites were determined by mapping a late and spiky "slow pathway potential" in the posterior right atrial septum in common AVNRT, and also the earliest retrograde atrial activation over the retrograde slow pathway in uncommon AVNRT. AVNRT was successfully eliminated in all patients with a mean number of radiofrequency pulses of 2.9 +/- 3.0 and a mean total energy applied of 3536 +/- 2996 joules. There were no early or late complications, except for transient AV block for 15 sec immediately after energy application in one common AVNRT patient, and no recurrence of AVNRT in a mean follow-up period of 24 +/- 13 months. There were no significant differences between common and uncommon AVNRT in success rate, mean application number and total energy applied. However, the AVN physiology post-ablation was different. Slow pathway conduction was eliminated in only 32% of the patients post-ablation in common AVNRT, while it was elininated in 100% in uncommon AVNRT. Selective radiofrequency catheter ablation of the slow pathway can cure common and uncommon AVNRT effectively and safely. Common AVNRT can be eliminated irrespective of the persistence of slow pathway conduction, while uncommon AVNRT can be eliminated by the eradication of slow pathway conduction.
Robust Data Hiding for MCLT Based Acoustic Data Transmission (2010)

Acoustic data transmission enables a short-range wireless communication between the loudspeaker and microphone. A transmitter embeds a data stream into a base audio signal such as music or commercial advertisement and broadcasts the data through the air by playing back the data-embedded sound using a loudspeaker. A receiver picks up the sound signal using microphone and extracts the hidden message. In our previous work, we proposed an acoustic data transmission system which takes advantage of the phase modification of the modulated complex lapped transform (MCLT) coefficients. In this letter, we propose several techniques to realize a more robust communication system in real noisy environment.
Axillary temperature in relation to oral temperature in a group of children in Sri Lanka. (1981)

The relationship between the oral temperature (OT) and the axillary temperature (AT) is not clearly established. The measurement of the OT could be an unhygienic procedure. Therefore, a study was done to determine the nature of relationship between OT and AT and whether AT could be used in place of OT. The OT and AT were measured in a group of children with OT's ranging from 97 degrees F (36 degrees C) to 105 degrees F (40.5 degrees C). The average difference of OT minus AT was statistically determined to be 0.3 degrees F (0.15 degrees C) throughout the range of temperatures tested. The correlation (r) between OT and AT was 0.99 (p less than 0.001). The AT is recommended as a reliable measure to be used in routine assessment of body temperature.
