Esculin and ferric citrate-incorporated sturgeon skin gelatine as an antioxidant film for food packaging to prevent<i>Enterococcus faecalis</i>contamination (2020)

Herein, a sturgeon skin gelatine film combined with esculin and ferric citrate was developed as an edible food packaging material to prevent Enterococcus faecalis (E. faecalis) contamination. E. faecalis is able to hydrolyse esculin in the film, and then the hydrolysed product, esculetin, combines with ferric citrate to form a brown-black phenol iron complex. This phenomenon can be observed easily after 48 h of contamination under visible light, and it can be determined under 365 nm ultraviolet light with high sensitivity. With the addition of esculin and ferric citrate, the film showed better mechanical properties and water vapour permeability than those of the unmodified gelatine. When an increased amount of esculin was added, an increase in thermal stability, antioxidant activity, and antioxidant stability of the film was observed. These physicochemical characteristics are beneficial for developing a packaging material for food storage that mitigates foodborne illness caused by E. faecalis.
Stimulated Brillouin scattering techniques for phase-locked phase conjugation (1994)

Phase-locked phase conjugation is the process of phase conjugating a number of laser beams whilst preserving their relative phases. Phase-locking is necessary when parallel laser amplifier channels are combined using phase conjugation, or when a depolarised beam is split into two orthogonal polarisations and phase conjugated.
M. tuberculosis Peptide based Point-of care test for TB (2014)

Methods Immunodominant regions of 3 Mycobacterium tuberculosis specific cell–wall proteins that are highly immunogenic in HIVTB+ and HIV+TB+ patients have been mapped. Antibodies to these regions are absent in subjects with latent TB, BCG vaccination, other pulmonary diseases. To examine the feasibility of devising a peptide based rapid POC test, selected peptides were conjugated to a carrier protein using standard EDC/NHS coupling chemistry, purified by size exclusion; the peptide conjugation confirmed using MALDI MSMS before adsorption onto colloidal gold and striping onto nitrocellulose. The assay parameters were adjusted to determine positive/negative status within 15 minutes via visual or instrumented assessment.

Performance of Leishmania PFR1 recombinant antigen in serological diagnosis of asymptomatic canine leishmaniosis by ELISA (2017)

The ability shown by the PFR1 ELISA to detect infected dogs that go undetected by the crude antigen ELISAs is clinically and epidemiologically useful and PFR1 could be considered a candidate for a multi-antigen-based immunoassay for early detection of L. infantum infected dogs.
LCoS SLM Study and Its Application in Wavelength Selective Switch (2017)

The Liquid-Crystal on Silicon (LCoS) spatial light modulator (SLM) has been used in wavelength selective switch (WSS) systems since the 1990s. However, most of the LCoS devices used for WSS systems have a pixel size larger than 6 µm. Although there are some negative physical effects related to smaller pixel sizes, the benefits of more available ports, larger spatial bandwidth, improved resolution, and the compactness of the whole system make the latest generation LCoS microdisplays highly appealing as the core component in WSS systems. In this review work, three specifications of the WSS system including response time, crosstalk and insertion loss, and optimization directions are discussed. With respect to response time, the achievements of liquid crystal material are briefly surveyed. For the study of crosstalk and insertion loss, related physical effects and their relation to the crosstalk or insertion loss are discussed in detail, preliminary experimental study for these physical effects based on a small pixel LCoS SLM device (GAEA device, provided by Holoeye, 3.74 µm pixel pitch, 10 megapixel resolution, telecom) is first performed, which helps with predicting and optimizing the performance of a WSS system with a small pixel size SLM. In the last part, the trend of LCoS devices for future WSS modules is discussed based on the performance of the GAEA device. Tradeoffs between multiple factors are illustrated. In this work, we present the first study, to our knowledge, of the possible application of a small pixel sized SLM as a switching component in a WSS system.
Yb14MnSb11 as a High-Efficiency Thermoelectric Material (2009)

Yb14MnSb11 has been found to be wellsuited for use as a p-type thermoelectric material in applications that involve hotside temperatures in the approximate range of 1,200 to 1,300 K. The figure of merit that characterizes the thermal-to-electric power-conversion efficiency is greater for this material than for SiGe, which, until now, has been regarded as the state-of-the art high-temperature ptype thermoelectric material. Moreover, relative to SiGe, Yb14MnSb11 is better suited to incorporation into a segmented thermoelectric leg that includes the moderate-temperature p-type thermoelectric material CeFe4Sb12 and possibly other, lower-temperature p-type thermoelectric materials. Interest in Yb14MnSb11 as a candidate high-temperature thermoelectric material was prompted in part by its unique electronic properties and complex crystalline structure, which place it in a class somewhere between (1) a class of semiconducting valence compounds known in the art as Zintl compounds and (2) the class of intermetallic compounds. From the perspective of chemistry, this classification of Yb14MnSb11 provides a first indication of a potentially rich library of compounds, the thermoelectric properties of which can be easily optimized. The concepts of the thermoelectric figure of merit and the thermoelectric compatibility factor are discussed in Compatibility of Segments of Thermo - electric Generators (NPO-30798), which appears on page 55. The traditional thermoelectric figure of merit, Z, is defined by the equation Z = alpha sup 2/rho K, where alpha is the Seebeck coefficient, rho is the electrical resistivity, and k is the thermal conductivity.
Acid Soluble Drilling Fluids: Development and Field Trial (2017)

Abstract Stuck pipe can not only significantly increase the cost of drilling but also has the potential to decrease the chances of successfully drilling a well within the stipulated time. A number of techniques and tools have been developed to solve the stuck pipe problem after they occur. However, the real objective should be to avoid the problem of stuck pipe to begin with and if and when they occur, the choice of treatment to release a stuck pipe should be such that it is not only cost effective but also quick. Such an objective prompted us to develop a new drilling fluid formulated with a combination of two different weighting agents, viz. barite and manganese tetroxide (Mn3O4). This paper describes the formulation of medium and high-density drilling fluids viz. 120 pcf and 150 pcf density fluids. These drilling fluids have been formulated with a combination of barite and Mn3O4 as weighting materials and hot rolled at 250°F and 300°F, respectively. After hot rolling these fluids at the specified temperatures, rheological properties and high temperature, high pressure (HTHP) fluid loss were measured. Sag resistance of the drilling fluids was estimated by perfoming static aging experiments in which the fluids were aged in inclined and vertical positions. To evaluate the filter-cake breaking potential of these mangansese tetroxide based drilling fluids, different breaker fluids were tested on the new 100pcf drilling fluid so as to calculate the % filter-cake removal efficiency. The paper also describes the data obtained from the field trial of 100 pcf and 145 pcf fluids formulated with barite and Mn3O4 for wells with a BHST of 290°F. The paper discusses the benefits of using drilling fluids formulated with barite and manganese tetroxide in mitigating stuck pipe issues and highlights their benefits in terms of better barite sag resistance and lower equivalent circulating density as compared to conventional drilling fluids formulated with 100% barite as weighting agent. The 120 pcf fluid when static agend showed superior rheology, thin filter cake and better sag resistance as compared to the 120pcf fluid formulated with only barite as the weighting agent. Different filter-cake breaker fluids have been showon to partially dissolve the filter cake of drilling fluids formulated with the acid-soluble manganese tetroxide as a weighting agent. This partial dissolution of filter cake is sufficient to free the pipe in the case of any stuck pipe event in the wellbore. The drilling fluids formulated with a combination of barite and manganese tetroxide showed good rheology, barite-sag resistance and resulted in successful drilling of wells having a BHST of 290°F.

Ag<sub>2</sub>O<sub>3</sub>, a Novel Binary Silver Oxide (1985)

Crystalline silver( III ) oxide , which is stable over prolonged periods at −20°C, was obtained by anodic oxidation of AgClO 4 , AgBF 4 or AgPF 6 (not AgNO 3 ) in aqueous solution. The oxide of definite composition Ag 2 O 3 was hitherto unknown. It arouses interest as a possible component of the anodes in zinc/silver oxide primary cells. According to an X‐ray structure analysis, the silver atoms in Ag 2 O 3 are coordinated by an almost square‐planar array of oxygen atoms. The AgO 4 groups are coupled via common oxygen atoms to give a three‐dimensional network.
Circumventing Traditional Conditioning Protocols in Polymer Membrane-Based Ion-Selective Electrodes (2016)

Preparation of ion-selective electrodes (ISEs) often requires long and complicated conditioning protocols limiting their application as tools for in-field measurements. Herein, we eliminated the need for electrode conditioning by loading the membrane cocktail directly with primary ion solution. This proof of concept experiment was performed with iodide, silver, and sodium selective electrodes. The proposed methodology significantly shortened the preparation time of ISEs, yielding functional electrodes with submicromolar detection limits. Moreover, it is anticipated that this approach may form the basis for the development of miniaturized all-solid-state ion-selective electrodes for in situ measurements.
Remotely induced atmospheric lasing (2011)

We propose and analyze a remote atmospheric lasing configuration which utilizes a combination of an ultrashort pulse laser to form a plasma filament (seed electrons) by tunneling ionization and a heater pulse which thermalizes the seed electrons. Electrons collisionally excite nitrogen molecules and induce lasing in the ultraviolet. The lasing gain is sufficiently high to reach saturation within the length of the plasma filament. A remotely generated ultraviolet source may have applications for standoff detection of biological and chemical agents.
Remote sensing of wind velocity and strength of refractive turbulence using a two-spatial-filter receiver (1994)

Wind velocity across an optical path and refractive turbulence strength can be measured by observing a light source through the atmosphere with a receiver that contains two spatial filters. The frequency of the detected signal gives the transverse velocity of the turbulent structure, whereas signal intensity is proportional to refractive turbulence strength. The size of turbulent eddies that produce signals is determined by the optical setup. The position along the detector's field of view at which the measurement is made depends on the separation of the filters, and profiles can be made by varying the separation and using a telescope. The system requires longer integration times than one which uses a spatial filter at each end of the optical path, but it has the advantage of being able to use a natural source such as the Sun or a planet. An analysis of the system is presented along with numerical simulations and results from a short-range (several meters) laboratory experiment. The analysis assumes a single layer of refractive turbulence. Scales of the refractive turbulence in the inertial subrange from 5 to 20 cm will be of primary interest for this method.
Programming with Functional Memory (1994)

Functional memory (FM) uses memory mapped reprogrammable field programmable gate arrays (FPGAs) for fine-grained parallel processing. Multi-operand expressions are computed in combinational logic eliminating processor computation steps. FPGAs capture operands as memory is written, eliminating separate processor load-stores to pass operands. This paper describes how program expressions can be implemented in FM, including branch address computations. It concludes with a load store analysis comparing a conventional von Neumann processor with and without FM for a shortest path program. The load store count stays about the same but eliminating the computation steps results in a one-third step reduction overall with FM.
Design Of Neural Net To Detect Early Stage Of Fire And Evaluation By Using Real Sensors' Data (1994)

Sensitive fire sensors are necessary to detect fires in their early stage, but they often produce false alarms from non-fire phenomena. It has lately become clear that fire and non-fire patterns exist as a result of analyzing fire and non-fire testing data. Changing the rate of sensor output per minute and normalized sensor output is used as patterns for analyzing sensors' data in various conditions. An odor sensor and a smoke sensor are very effective in discriminating between fire / non-fire phenomena by adopting artificial neural net which has been trained to recognize their patterns.

Mapping of a cholinergic binding site by means of synthetic peptides, monoclonal antibodies, and .alpha.-bungarotoxin (1990)

Previous studies by several laboratories have identified a narrow sequence region of the nicotinic acetylcholine receptor (AChR) alpha subunit, flanking the cysteinyl residues at positions 192 and 193, as containing major elements of, if not all, the binding site for cholinergic ligands. In the present study, we used a panel of synthetic peptides as representative structural elements of the AChR to investigate whether additional segments of the AChR sequences are able to bind alpha-bungarotoxin (alpha-BTX) and several alpha-BTX-competitive monoclonal antibodies (mAbs). The mAbs used (WF6, WF5, and W2) were raised against native Torpedo AChR, specifically recognize the alpha subunit, and bind to AChR is inhibited by all cholinergic ligands. WF6 competes with agonists, but not with low mol. wt. antagonists, for AChR binding. The synthetic peptides used in this study were approximately 20 residue long, overlapped each other by 4-6 residues, and corresponded to the complete sequence of Torpedo AChR alpha subunit. Also, overlapping peptides, corresponding to the sequence segments of each Torpedo AChR subunit homologous to alpha 166-203, were synthesized. alpha-BTX bound to a peptide containing the sequence alpha 181-200 and also, albeit to a lesser extent, to a peptide containing the sequence alpha 55-74. WF6 bound to alpha 181-200 and to a lesser extent to alpha 55-74 and alpha 134-153. The two other mAbs predominantly bound to alpha 55-74, and to a lesser extent to alpha 181-200. Peptides alpha 181-200 and alpha 55-74 both inhibited binding of 125I-alpha-BTX to native Torpedo AChR. None of the peptides corresponding to sequence segments from other subunits bound alpha-BTX or WF6, or interfered with their binding. Therefore, the cholinergic binding site is not a single narrow sequence region, but rather two or more discontinuous sequence segments within the N-terminal extracellular region of the AChR alpha subunit, folded together in the native structure of the receptor, contribute to form a cholinergic binding region. Such a structural arrangement is similar to the "discontinuous epitopes" observed by X-ray diffraction studies of antibody-antigen complexes [reviewed in Davies et al. (1988)].
Extracellular matrix signatures of human primary metastatic colon cancers and their metastases to liver (2014)

The ECM protein signatures of metastatic primary colon carcinomas and metastases to liver defined in this study, offer promise for development of diagnostic and prognostic signatures of metastatic potential of colon tumors. The ECM proteins defined here represent candidate serological or tissue biomarkers and potential targets for imaging of occult metastases and residual or recurrent tumors and conceivably for therapies. Furthermore, the methods described here can be applied to other tumor types and can be used to investigate other questions such as the role of ECM in resistance to therapy.
Wavelength referencing in single-mode microbend sensors (1987)

The strong wavelength dependence of microbending losses in single-mode fibers is utilized in wavelength referencing for fluctuation-free microbend sensors. Through fiber size and microbend periodicity, optimization of the wavelength dependence can be increased dramatically. The reference and signal wavelengths can be provided through the spectrum of a light-emitting diode.
Novel material identification method using three energy bins of a photon counting detector taking into consideration Z-dependent beam hardening effect correction with the aim of producing an X-ray image with information of effective atomic number (2017)

Energy resolved photon counting detectors have been developed and currently in use, we have proposed practical methods for producing an X-ray image having effective atomic number information by means of plain X-ray diagnosis. An effective atomic number image is hoped to be used to enhance its value and to carry out more precise clinical diagnosis. In this study, we aimed to propose a novel material identification method using three energy bins of a photon counting detector. First, we prepared theoretical X-ray spectra and X-ray spectra folded with the response function of a multi-pixel-type CdTe detector. The response function was simulated using the Monte-Carlo simulation code EGS5. Next, the X-ray spectra were divided into three energy bins and the products of linear attenuation coefficient and material thickness for low, middle, and high energy bins were derived from the difference of counts before and after the X-ray penetrated the material. In order to accomplish accurate material identification, beam hardening corrections for derived attenuation factors were individually applied. In order to take consideration the dependence of atomic numbers on the beam hardening corrections, we propose a novel method in which the relationship between mass thickness multiplied by mass attenuation coefficient and attenuation factor was used. Then, using the corrected attenuation factors, normalized linear attenuation coefficients for lower and higher energy bins were calculated, and they were converted to effective atomic numbers using the theoretically determined relationships. In the present study, two different effective atomic numbers, Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Low</sub> and Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">High</sub> , were individually determined from the analysis of lower and higher energy bins. Here, if beam hardening corrections were properly calculated, Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Low</sub> and Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">High</sub> become an equal value which is also consistent with the true value. Using virtual materials for Z = 5-13 with mass thicknesses of 1-10 [g/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ], we confirmed that our method works properly.
Experimental Maintenance of Chaos (1995)

We present a method for the anticontrol or maintenance of chaos designed for easy application to physical and biological systems. The method is based on the return map of the experimental data and requires only small, very infrequently applied time-dependent perturbations of a single system parameter and does not require any model equations for or a priori knowledge of the system dynamics. The method is shown to be able to reliably sustain chaos in a magnetomechanical ribbon experiment.
