The Condition Monitoring of Rolling Element Bearings Using Vibration Analysis (1984)

A brief review on techniques of machine condition monitoring is presented followed by a description and results of a study involving the monitoring of vibration signatures of several rolling element bearings with a view to detecting incipient failure. The vibration data were analyzed and several parameters were assessed with regard to their effectiveness in the detection of bearing condition. It was found that all the parameters were of some value depending on the type of bearing failure encountered. Generally, frequency domain parameters were more consistent in the detection of damage than time domain parameters. However, sufficient evidence is produced to show that it would be unreliable to depend exclusively on any one technique to detect bearing damage.
High‐Performance Langmuir–Blodgett Monolayer Transistors with High Responsivity (2010)

Molecular field-effect transistors with bulk-like carrier mobility (as high as 0.04 cm2 V−1 s−1), high on/off current ratios (over 106), and high responsivity are formed by the integration of Langmuir–Blodgett techniques with sophisticated micro/nanofabrication. The transistors are formed from self-assembled uniform monolayers of copper phthalocyanine (CuPc) semiconductors and single-layer graphene as planar contacts.

S19 ribosomal protein dimer augments metal‐induced apoptosis in a mouse fibroblastic cell line by ligation of the C5a receptor (2004)

To analyze the role of S19 ribosomal protein (RP S19) in apoptosis, murine NIH3T3 were transfected with either hemagglutinin peptide-tagged (HA) wild-type human RP S19 or a mutant (Gln137Asn) that is resistant to transglutaminase-catalyzed cross-linked-dimerization. Transfection with the mutant HA-RP S19 inhibited manganese (II) (Mn II)-induced apoptosis whereas the wild-type HA-RP S19 augmented apoptosis and a mock transfection had no effect. Release of the wild-type HA-RP S19 dimer but not the mutant HA-RP S19 was observed during the apoptosis. The reduced rate of apoptosis of the cells transfected with the mutant HA-RP S19 was overcome by addition of extracellular wild-type RP S19 dimer. The apoptosis rates in cells transfected with either form of human HA-RP S19 and in mock transfectants were reduced to about 40% by the presence of anti-RP S19 antibody in the culture medium. Immunofluorescence staining and fluorescence-activated cell sorting (FACS) analysis showed that the cell surface expression of the receptor for cross-linked RP S19 dimer, C5a receptor, increased during apoptosis, concomitant with phosphatidylserine exposure. The expression of the C5a receptor gene also increased twofold. Apoptosis rates in the transfected and control cell lines were also reduced by the presence of an anti-mouse C5a receptor monoclonal antibody or of a peptide C5a receptor antagonist. These results indicated the presence of an RP S19 dimer- and C5a receptor-mediated autocrine-type augmentation mechanism during Mn II-induced apoptosis in the mouse fibroblastic cell line. In contrast to the RP S19 dimer, C5a actually inhibited apoptosis, suggesting that signaling through the C5a receptor varies depending on the ligand bound.
Photometry of the Wolf-Rayet binary HD 211853 in the Vilnius photometric system. (1994)

New photometric observations of the Wolf-Rayet binary HD 211853 are presented. The period search routine confirms the period of 6.6884 days for pair A. For pair B, a new corrected ephemeris (T 0 = 2443689.16, P = 3.4696 days) is determined. This ephemeris allows to present light minima of all available photometric data in the same phase. Moreover, they are in good accordance with the absorption lines radial velocity residuals of Hiltner (1945) and Massey (1981). It is shown that the third possible period of 2.34607 days found by Panov & Seggewiss (1990) is an alias from the half period of ∼ 3.47 days

Ultraviolet–visible and electron paramagnetic resonance spectroelectrochemical studies of the reduction products of some anthraquinone sulphonates in aqueous solutions (1991)

The reductions of a range of anthraquinone sulphonates have been studied by cyclic voltammetry using gold and platinum electrodes. Reductions of the 2-sulphonates in tetraethylammonium hydroxide solutions exhibit two distinct one-electron peaks in the voltammograms in contrast to the single peaks observed from alkali-metal hydroxide solutions. Discrete UV–VIS absorption spectra of the radical anion and quinolate dianion of the 2-sulphonates have been recorded from tetraethylammonium hydroxide solutions using an optically transparent thin-layer electrode (gold minigrid) cell. Studies at different pH values have shown that the most prominent absorption of the 2-sulphonate dianions shows characteristic shifts to shorter wavelengths with each stage of protonation. Observation of the EPR spectra of the radical anion species, electrogenerated in a thin-layer cell, confirms their UV–VIS spectral assignments. The resulting hyperfine splitting constants were assigned to specific proton positions using the additivity principle and the simple Hückel method.
Pulse code modulation techniques : with applications in communications and data recording (1995)

Commercial uses include audio CD and digital audio tape. Each chapter introduces topics, presents intuitive or ad hoc design methods and relates theoretical results to practical design problems. It covers PCM systems from the channel coder at one end to the decoder at the other, including modulation and demodulation functions and a discussion of the communication channel itself.
Synchronous Adenocarcinoma and Mucosa-associated Lymphoid Tissue (MALT) Lymphoma in a Single Stomach (2005)

Although gastric adenocarcinoma coexists with MALT lymphoma at a relatively high frequency, synchronous carcinoma can be misinterpreted as a multifocal separated lesion of MALT lymphoma owing to their macroscopic resemblance. Therefore, gastric MALT lymphoma patients should be carefully examined by endoscopy, and any suspicious area must be biopsied considering the possibility of coexisting adenocarcinoma. In addition, etiologies other than H. pylori should be considered in these synchronous tumors.
Probiotics in The Treatment of Irritable Bowel Syndrome (2004)

Irritable Bowel Syndrome (IBS) may be diagnosed on the presence of symptoms, according to Rome II criteria, [corrected] and some studies have shown that abnormal colonic fermentation may be an important factor in the development of symptoms in some patients with IBS. Since the fermentation [corrected] of substrates by the intestinal flora may play a key role in the use of probiotics in the treatment of IBS, seventy [corrected] patients (31 [corrected] males, 39 [corrected] females), mean age 40 years (range = 26-64 years) with IBS, according to Rome II criteria, were enrolled into the study after informed consensus. Patients were randomly assigned to receive for 4 weeks [corrected] either the active preparation containing Lactobacillus plantarum LP 01 [corrected] and Bifidobacterium breve BR 03 [corrected] or Lactobacillus plantarum LP 01 and Lactobacillus acidophilus LA 02, all strains at concentrations of 5 x 10(9) CFU/g) [corrected] or placebo powder containing starch identical to the study product [corrected] To evaluate treatment efficacy two different scores were considered [corrected] Pain score in different abdominal locations after treatment decreased in probiotics groups A and B 42% and 49% versus 25% [corrected] (P < 0.05) in [corrected] placebo group after 14 days and 45% and 49% versus 29.5% [corrected] (P < 0.001) after 28 days. The severity score of characteristic IBD symptoms significantly decreased in probiotic groups A and B [corrected] versus placebo group after 14 days, 49.3% and 55.6% [corrected] versus 8% [corrected] (P < 0.001), and these data were confirmed after 28 days (56% and 55.6% versus 14.4% [corrected] P < 0.001). In conclusion, short-term therapy with Lactobacillus plantarum LP 01 and Bifidobacterium breve BR 03 or Lactobacillus plantarum LP 01 and Lactobacillus acidophilus LA 02 [corrected] may be considered a promising approach for IBS therapy [corrected]
Polyaniline‐multiwalled carbon nanotube composites: Characterization by WAXS and TGA (2008)

Abstract Polyaniline/carboxylated multi‐walled carbon nanotube (PAni/c‐MWNT) nanocomposites have been synthesized by micellar aided emulsion polymerization with various c‐MWNTs compositions, viz., 0.5, 1, 5, and 10 wt %. The microcrystalline parameters such as the nanocrystal size (〈 N 〉), lattice strain ( g ), interplanar distance ( d hkl ), width of the crystallite size distribution, surface weighted crystal size ( D s ), and volume of the ordered regions were calculated from the X‐ray data by using two mathematical models, namely the Exponential distribution and Reinhold distribution methods. The effects of heat ageing on the microcrystalline parameters of the PAni/c‐MWNT nanocomposites were also studied and the results are correlated. The thermal stability and electrical resistivity of the PAni/c‐MWNT nanocomposites were examined with thermogravimetric analysis (TGA) and a conventional two‐probe method. The TGA data indicate that the thermal stability of the nanocomposites improved after the incorporation of c‐MWNTs. The influence of temperature on the resistivity of the nanocomposites was also measured. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci 2008
Calculation of Induced Electric Field During a Geomagnetic Storm Using Recursive Convolution (2014)

The relationship between the changes in the earth's magnetic field and the induced geoelectric field during a geomagnetic disturbance is a frequency-dependent transfer function that depends on earth resistivity at different depths. Traditionally, this function is calculated in the frequency domain expressed as an impulse function in the time domain using fast Fourier transform (FFT) and convolved with dB/dt in the time domain to estimate the geoelectric field E. This paper proposes the approximation of the transfer function in the frequency domain using rational functions and to carry out the calculation of E from dB/dt using fast recursive convolution methods.
Obfuscated instructions for software protection (2003)

Many computer systems are designed to make it easy for end-users to install and update software. An undesirable side-effect, from the perspective of many software producers, is that hostile end-users may analyze or tamper with the software being installed or updated. This paper proposes a way to avoid the side-effect without affecting the ease of installation and update. We construct a computer system M with the following properties: 1) the end-user may install program P in any conveniently accessible area of M; 2) the program P contains obfuscated instructions whose semantics are obscure and difficult to understand; and 3) an internal interpreter W, embedded in a non-accessible area of M, interprets the obfuscated instructions without revealing their semantics. Our W is a finite state machine (FSM) which gives context-dependent semantics and operand syntax to the obfuscated instructions in P; thus, attempts to statically analyze the relation between instructions and their semantics will not succeed. We present a systematic method to construct a P whose instruction stream is always interpreted correctly regardless of its input, even though changes in input will (in general) affect the execution sequence of instructions in P. Our framework is easily applied to conventional computer systems by adding a FSM unit to a virtual machine or a reconfigurable processor.
SMARTDIAB: A Communication and Information Technology Approach for the Intelligent Monitoring, Management and Follow-up of Type 1 Diabetes Patients (2010)

SMARTDIAB is a platform designed to support the monitoring, management, and treatment of patients with type 1 diabetes mellitus (T1DM), by combining state-of-the-art approaches in the fields of database (DB) technologies, communications, simulation algorithms, and data mining. SMARTDIAB consists mainly of two units: 1) the patient unit (PU); and 2) the patient management unit (PMU), which communicate with each other for data exchange. The PMU can be accessed by the PU through the internet using devices, such as PCs/laptops with direct internet access or mobile phones via a Wi-Fi/General Packet Radio Service access network. The PU consists of an insulin pump for subcutaneous insulin infusion to the patient and a continuous glucose measurement system. The aforementioned devices running a user-friendly application gather patient's related information and transmit it to the PMU. The PMU consists of a diabetes data management system (DDMS), a decision support system (DSS) that provides risk assessment for long-term diabetes complications, and an insulin infusion advisory system (IIAS), which reside on a Web server. The DDMS can be accessed from both medical personnel and patients, with appropriate security access rights and front-end interfaces. The DDMS, apart from being used for data storage/retrieval, provides also advanced tools for the intelligent processing of the patient's data, supporting the physician in decision making, regarding the patient's treatment. The IIAS is used to close the loop between the insulin pump and the continuous glucose monitoring system, by providing the pump with the appropriate insulin infusion rate in order to keep the patient's glucose levels within predefined limits. The pilot version of the SMARTDIAB has already been implemented, while the platform's evaluation in clinical environment is being in progress.
Advantages of a New, Atraumatic, Self-Retaining Electrode for Direct Cochlear Nerve Monitoring (1997)

Direct cochlear nerve monitoring during posterior fossa surgery offers the surgeon real-time information concerning auditory stams. However, routine utilization of this monitoring technique has been hampered by electrode designs that have not allowed the maintenance of a consistent contact between the nerve and electrode. We report on our experience with a new electrode designed to maintain consistent, atraumatic contact with the cochlear nerve and discuss the advantages of this electrode over existing wick and ball type electrodes.The utilization of this electrode during 18 posterior fossa surgeries, performed at Kaiser Permanenie Hospital, San Diego, including 8 vestibular schwannoma resections, allowed for consistent recording of high amplitude cochlear compound action potentials. Long-term exposure to pulsating cerebrospinal fluid (CSF) did not displace the electrode. Minimal cochlear nerve action potential amplitude change was noted with the electrode imrnersed in CSF. The electrode caused no trauma to the nerve, even in cases where it was accidentally dislodged from the nerve. It is hoped that by overcoming the problems previously associated with direct cochlear nerve monitoring, this electrode will allow for increased use of this advantageous monitoring technique. As a by product of the real-time data provided to the surgeon, we anticipate increased rates of hearing preservation during cerebellopontine angle surgery.
Substituent Effect on Electrochemical and Electrochromic Behaviors of Ambipolar Aromatic Polyimides Based on Aniline Derivatives (2011)

Three series of new ambipolar polyimides containing aniline derivatives with different degree of 4-methoxyphenyl substituent showing anodically/cathodically electrochromic characteristic were prepared from the polycondensation of three diamine monomers—4,4′-bis[(4-aminophenyl)amino]diphenylamine (3), 4,4′-bis[(4-aminophenyl)amino]-4″-methoxytriphenylamine (3′), and 4,4′-bis[4-aminophenyl(4-methoxyphenyl)amino]-4″-methoxytriphenylamine (3″)—with various commercially available tetracarboxylic dianhydrides. In addition to the high glass-transition temperatures (Tg, 246–339 °C), thermal stability, and solution processability, the resulting polyimide films exhibited ambipolar electrochromic behavior. The nonconjugated TPA-based polyimides III revealed more stable electrochemical oxidation behavior and better electrochromic reversibility than conjugated DPA-based corresponding polyimides I due to the additional phenyl ring providing the route to stabilize the cation radical formed during oxidation.
A modified TALEN-based system for robust generation of knock-out human pluripotent stem cell lines and disease models (2013)

Numerical methods for colorimetric calculations: Sampling density requirements (1992)

Abstract This article quantifies errors arising from various integration methods and from sampling density in the numerical estimation of colorimetric integrals, e.g., tristimulus values. Both data sampling density and various numerical integration method errors will be distinguished. A test is presented to quantify sampling interval requirements for accurate colorimetric calculations for various illuminants. © 1992 John Wiley & Sons, Inc.
Chemical Sensing in Process Analysis (1984)

Improvements in process control, which determine production efficiency and product quality, are critically dependent upon on-line process analysis. The technology of the required instrumentation will be substantially expanded by advances in sensing devices. In the future, the hardware will consist of sensor arrays and miniaturized instruments fabricated by microlithography and silicon micromachining. Chemometrics will be extensively used in software to provide error detection, selfcalibration, and correction as well as multivariate data analysis for the determination of anticipated and unanticipated species. A number of examples of monolithically fabricated sensors now exist and more will be forthcoming as the new paradigms and new tools are widely adopted. A trend toward not only on-line but even in-product sensors is becoming discernible.
Needle Insertion Manipulator for CT-guided Stereotactic Neurosurgery (1993)

Image guided stereotactic surgery is a less invasive method for many neurosurgical procedures as biopsy, laser therapy or hyperthermia. This method precisely localizes a needle to the target lesion after measuring target position with CT/MR images. We have developed a needle insertion manipulator system for CT-guided stereotactic surgery. Our system consists of a needle insertion manipulator and its PC-based controller. The manipulator, which is placed on a stereotactic frame, has six degree-of-freedom of movement: X, Y, Z for needle localization, φ, θ for needle direction, and S for needle insertion. As using stepping motors for all axes, the manipulator has a positioning precision of less than0.1mm. In case of accident, this system can immediately stop the motion of manipulator by cutting off the power supply to motors, and axes are held rigidly to avoid interference to the patient and surgeons. A phantom study using X-ray CT images has shown the following: 1)The top of the needle was located to the target with 1.0mm of error: it is sufficient for most stereotactic operations, considering CT image resolution(0.5mm per pixel). 2)No artifact on CT images caused by the manipulator was found. 3)The manipulator was small enough to be set in CT gantry(600mm in diameter).
Selective Inhibition of Deoxyribonucleic Acid Synthesis by Salicylhydroxamic Acid. (1966)

Salicylhydroxamic acid (SHA) was shown to be a selective inhibitor of DNA synthesis by Ehrlich ascites tumor cells in vitro. Inhibition was evident virtually immediately after addition of the compound to the cells; no preincubation was necessary to evoke the effect. Cells which were preincu-bated with SHA for up to 2 hours showed only a slight depression of RNA synthesis, while the rate of protein synthesis was unaltered. Reversal of the inhibition upon removal of SHA was complete at lower concentrations, and partial at higher concentrations.
Materialistic Cue Effects in Print Advertising (2002)

Abstract This study examines the effects of a materialistic context of an ad on judgments and evaluations of the advertised product. Here, the ad context refers to the pictorial background setting of the ad. Findings from an experiment with consumers illustrate that similarity/dissimilarity between the ad context and the product information presented in the ad produces context effects. These findings support the assimilation/contrast framework. Implications for context effect research and materialism are also discussed.
The preparation of eye-preserving glass for spectacles (1914)

Abstract Since March, 1909–in connection with the Glass Workers' Cataract Committee of the Royal Society–I have been experimenting on the effect of adding various metallic oxides to the constituents of glass in order to cut off the invisible rays at the ultra-violet and the infra-red ends of the spectrum. The work has been done chiefly in my own laboratory. I have been aided by Mr. Harry Powell, of the Whitefriars Glass Works, who prepared several pots of coloured glass from my formulae on a much larger scale than could be made outside a glass works. From these glasses cylinders and sheets were made. The main object of this research is to prepare a glass which will cut off those rays from highly heated molten glass, which damage the eyes of workmen, without obscuring too much light or materially affecting the colours of objects seen through the glass when fashioned into spectacles, but the work necessitated an examination of the screening properties of glass plates for ultra-violet and luminous light, and therefore the research was enlarged so as to embrace the three forms of radiation.
