pyDVS: An extensible, real-time Dynamic Vision Sensor emulator using off-the-shelf hardware (2016)

Vision is one of our most important senses, a vast amount of information is perceived through our eyes. Neuroscientists have performed many studies using vision as input to their experiments. Computational neuroscientists have typically used a brightness-to-rate encoding to use images as spike-based visual sources for its natural mapping. Recently, neuromorphic Dynamic Vision Sensors (DVSs) were developed and, while they have excellent capabilities, they remain scarce and relatively expensive. We propose a visual input system inspired by the behaviour of a DVS but using a conventional digital camera as a sensor and a PC to encode the images. By using readily-available components, we believe most scientists would have access to a realistic spiking visual input source. While our primary goal is to provide systems with a live real-time input, we have also been successful in transcoding well established image and video databases into spike train representations. Our main contribution is a DVS emulator framework which can be extended, as we demonstrate by adding local inhibitory behaviour, adaptive thresholds and spike-timing encoding.
MEASUREMENT OF DYNAMIC STRAIN OF STRUCTURE SUBJECTED TO DYNAMIC LOAD BY USING A COUPLE OF VIBRATORY GYROSCOPE (1998)

The health monitoring of structure is to detect the cumulative damage by the fatigue of structure for the vibration caused by transportation, wind and earthquake etc. The signal according to development of fatigue crack shall be detected the displacement, velocity, acceleration and dynamic strain etc.. Usually, the dynamic strain is measured by using strain gauges. However, the strain gauges are not suitable for long term monitoring because the bonding material used to attach them to structure will become creep for long time usage. Then, for eliminating the disadvantage in using strain gauges, the method to measure the dynamic strain by vibratory gyroscopes is proposed for the health monitoring of structure and the eifectiveness is proved through experiments.

Comparison of the bisbiguanide antiseptics alexidine and chlorhexidine. I. Effect on plaque accumulation and salivary bacteria (1981)

A blind crossover trial was carried out to compare the effects of a 0.2% chlorhexidine gluconate mouthrinse and a 0.035% alexidine mouthrinse on plaque accumulation and salivary bacteria in a group of volunteers. The subjects refrained from all forms of oral hygiene during two 10-day periods and rinsed twice a day with the mouthwash randomly allocated to the respective period. Prerinse, day 4 and day 10 total salivary aerobic and anaerobic bacterial counts were determined during each period. Plaque scores were recorded at the end of each 10-day period. Significantly more plaque accumulated in subjects rinsing with alexidine when compared with chlorhexidine. Significant and comparable reductions in salivary bacterial counts were observed with both chlorhexidine and alexidine on day 4 and day 10 when compared with pre-rinse counts. Although at the concentrations used alexidine was less effective than chlorhexidine, it may be of value as a short-term adjunct to oral hygiene.
Gate‐Tunable Hole and Electron Carrier Transport in Atomically Thin Dual‐Channel WSe<sub>2</sub>/MoS<sub>2</sub> Heterostructure for Ambipolar Field‐Effect Transistors (2016)

An ambipolar dual-channel field-effect transistor (FET) with a WSe<sub>2</sub> /MoS<sub>2</sub> heterostructure formed by separately controlled individual channel layers is demonstrated. The FET shows a switchable ambipolar behavior with independent carrier transport of electrons and holes in the individual layers of MoS<sub>2</sub> and WSe<sub>2</sub> , respectively. Moreover, the photoresponse is studied at the heterointerface of the WSe<sub>2</sub> /MoS<sub>2</sub> dual-channel FET.
In Utero Cleft Lip Repair in A/J Mice (1985)

Reconstructive in utero microsurgery for repair of unilateral cleft lips has been technically achieved in the A/J mouse fetus. The period of gestation was undisturbed, and following birth, the gross and histologic appearance of the lips was nearly normal with no evidence of scar formation. The absence of a lip scar after human cheiloplasty may require the as yet undefined advantages of fetal wound healing.
Unit-Cube Expression for Space-Charge Resistance (1967)

A simple analysis shows that the unit-cube conductance is a figure of merit in semiconductor device design theory. The unit-cube conductance, G, is given by 2Kv <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</inf> where K is the permittivity of the semiconductor and v <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</inf> is the limiting drift velocity. The space-charge resistance, R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sc</inf> , due to carrier generated under avalanche condition is derived for p-n junctions. It is found that for parallel-plane structure, R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sc</inf> = 1/GN, where N is the number of unit cubes in the depletion region with cube edge equal to the depletion width or N = A/W <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> where W is the depletion width and A the junction area. The disturbance in voltage caused by the space-charge effect is given by I/GN = JW <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /G where I and J are the current and current density, respectively. Similar results are obtained for p-n junctions with coaxial-cylinder and concentric-sphere structures. For silicon, the value of G is approximately 40 μmhos. The transconductance of a silicon surface-controlled avalanche transistor in terms of the unit-cube expression is about 12.5 N μmhos.

BOVINE TUBERCULOSIS IN FREE-RANGING WHITE-TAILED DEER FROM MICHIGAN (1997)

A 4.5 yr-old male white-tailed deer (Odocoileus virginianus) killed by a hunter during the 1994 firearm hunting season in northeastern Michigan (USA) had lesions suggestive of tuberculosis and was positive on culture for Mycobacterium bovis the causative agent for bovine tuberculosis. Subsequently, a survey of 354 hunter-harvested white-tailed deer for tuberculosis was conducted in this area from 15 November 1995 through 5 January 1996. Heads and/or lungs from deer were examined grossly and microscopically for lesions suggestive of bovine tuberculosis. Gross lesions suggestive of tuberculosis were seen in 15 deer. Tissues from 16 deer had acid-fast bacilli on histological examination and in 12 cases mycobacterial isolates from lymph nodes and/or lungs were identified as M. bovis. In addition, lymph nodes from 12 deer (11 females and 1 male) without gross or microscopic lesions were pooled into 1 sample from which M. bovis was cultured. Although more male (9) than female (3) deer had bovine tuberculosis infections, this difference was not statistically significant. Mycobacterium bovis culture positive deer ranged in age from 1.5 to 5.5 yr with a mean of 2.7 yr (median 2.5 yr) for males and 3.2 yr (median 3.5 yr) for females. This appears to be the first epidemic occurrence of M. bovis in free-ranging cervids in North America. A combination of environmental (high deer density and poor quality habit) and management-related factors (extensive supplemental feeding) may be responsible for this epizootic.
An Analysis of a Course-Oriented Electronic Mailing List (1999)

To understand how course-oriented e-mail lists contribute to the learning experience and, more importantly, to understand how to improve the value of listservs in courses, it is important to critically examine their behavior under actual classroom conditions. We present an empirical study of listserv usage in a sophomore-level computer science data structures class. This study provides experimental evidence that: the list was an important information source for students, students were major contributors in answering the questions of others, students generally provided correct answers instead of incorrect help, and traffic on the list was driven by concrete tasks the students had to perform. As a result, the listserv was an effective tool for peer-to-peer learning, not just a mechanism for faculty to broadcast announcements. After presenting the study and results, we conclude by describing the lessons we learned on how to make a class-oriented listserv a successful environm ent for peer-to-peer learning, as well as the concomitant pitfalls.
EFFECT OF DECOLORIZATION AND LACTOSE INCORPORATION ON THE EMULSIFICATION CAPACITY OF SPRAYDRIED BLOOD PROTEIN CONCENTRATES (1973)

Blood protein concentrates were prepared from the serum and decolorized hemoglobin fractions of bovine blood. The emulsifying capacity of the concentrates was dependent on protein concentration and was not affected by spray drying. However, when the serum protein fraction was subjected to the decolorization treatment, its emulsifying capacity was reduced. Lactose, when added to the serum proteins prior to spray drying, prevented this reduction.
II.F.3 Solar-Thermal Hydrogen Production Using a Metal-Oxide Based Thermochemical Water Splitting Cycle (2010)

The most benign and renewable method for obtaining hydrogen is by using sunlight to split water. Splitting water directly with solar-thermal energy is not practical since the temperature required in order to obtain high conversion is above 4,000 K. Another huge challenge is the requirement to separate gaseous hydrogen from oxygen at these temperatures. Multistep thermochemical cycles which split water through a series of two or more chemical reactions provide an opportunity for carrying out the high step in the process at more modest temperatures of less than 2,000 K. In addition, they remove oxygen and hydrogen in separate steps, thus avoiding the recombination issues. The Mn2O3/MnO and ferrite cycles allow lower operating temperatures than other thermochemical cycles and are of particular interest.

Fabricating Multifunctional Nanoparticle Membranes by a Fast Layer-by-Layer Langmuir-Blodgett Process: Application in Lithium-sulfur Batteries (2016)

The Langmuir-Blodgett (LB) technique is a powerful, widely used method for preparing coatings of amphiphilic molecules at air/water interfaces with thickness control down to a single molecule. Here we report two new LB techniques designed to create ordered, multifunctional nanoparticle films on any non-reactive support. The methods utilize Marangoni stresses produced by surfactants at a fluid/solid/gas interface and self-assembly of nanoparticles to facilitate rapid creation of dense monolayers of multi-wall carbon nanotubes (MWCNT), metal-oxide nanoparticles, polymers, and combinations of these materials in a layer-by-layer configuration. Using the polyolefin separator in a lithium sulfur (Li-S) electrochemical cell as an example, we illustrate how the method can be used to create structured membranes for regulating mass and charge transport. We show that a layered MWCNT/SiO2/MWCNT nanomaterial created in a clip-like configuration, with gravimetric areal coverage of ~130 mg cm-2 and a thickness of ~3 micron, efficiently adsorbs dissolved lithium polysulfide (LiPS) species and efficiently reutilize them for improving Li-S battery performance.
Pheromone Synthesis, CLXXXV Synthesis of the Analogues of Lurlenic Acid with a Modified Sugar Part: <i>Chlamydomonas</i> responds only to the <scp>D</scp>‐xyloside (1997)

Abstract Six analogues of lurlenic acid [(4 E ,8 E ,12 E )‐14‐[2′‐hydroxy‐3′,4′‐dimethyl‐5′‐(1″‐β‐ D ‐xylopyranosyloxy)phenyl]‐4,8,12‐trimethyltetradeca‐4,8,12‐trienoic acid( 1 )], the mating pheromone of Chlamydomonas allensworthii , were synthesized as E/Z mixtures ( E/Z = 3:2) at C‐12. They possess a tetrahydropyranyl ( 1a ), β‐ L ‐xylopyranosyl ( 1b ), β‐ D ‐glucopyranosyl ( 1e ) or β‐ D ‐arabinopyranosyl ( 1f ) group, respectively, as the sugar part. Only lurlenic acid ( 1 ) was bioactive as the pheromone.
GaN-Based Ultraviolet Light Emitting Diodes With Ex Situ Sputtered AlN Nucleation Layer (2013)

We demonstrated the electro-optical characteristics of gallium nitride (GaN)-based ultraviolet (UV) light emitting diodes (LEDs) with sputtered aluminum nitride (AlN) nucleation layer. The introduction of the ex situ sputtered AlN nucleation layer improved the crystal quality of the GaN and the n-AlGaN layer of the GaN-based UV LEDs. Hence, the 20-mA output power of UV LEDs with ex situ AlN nucleation layers is higher than that of UV LEDs with GaN nucleation layers. In addition, the enhanced power output of UV LEDs with ex situ AlN nucleation could reach around 52% in magnitude at peak emission wavelengths of 370 nm compared with power outputs of UV LEDs with GaN nucleation layers. Furthermore, UV LEDs with ex situ AlN nucleation show improved reliability. The UV LEDs with ex situ AlN nucleation layer revealed a power output drop of around 9% within 168 hours , which is less than the around 14% power drop of UV LEDs with GaN nucleation layer.
Efficacy of reactive mineral-based sorbents for phosphate, bacteria, nitrogen and TOC removal – Column experiment in recirculation batch mode (2013)

Two mineral-based materials (Polonite and Sorbulite) intended for filter wells in on-site wastewater treatment were compared in terms of removal of phosphate (PO4-P), total inorganic nitrogen (TIN), total organic carbon (TOC) and faecal indicator bacteria (Escherichia coli and Enterococci). Using an innovative, recirculating system, septic tank effluent was pumped at a hydraulic loading rate of 3000 L m(2) d(-1) into triplicate bench-scale columns of each material over a 90-day period. The results showed that Polonite performed better with respect to removal of PO4-P, retaining on average 80% compared with 75% in Sorbulite. This difference was attributed to higher CaO content in Polonite and its faster dissolution. Polonite also performed better in terms of removal of bacteria because of its higher pH value. The total average reduction in E. coli was 60% in Polonite and 45% in Sorbulite, while for Enterococci the corresponding value was 56% in Polonite and 34% in Sorbulite. Sorbulite removed TIN more effectively, with a removal rate of 23%, while Polonite removed 11% of TIN, as well as TOC. Organic matter (measured as TOC) was accumulated in the filter materials but was also released periodically. The results showed that Sorbulite could meet the demand in removing phosphate and nitrogen with reduced microbial release from the wastewater treatment process.
Super-Resolution Digital Pathology Image Processing of Bone Marrow Aspirate and Cytology Smears and Tissue Sections (2018)

Influence of response factors on determining equilibrium association constants of non‐covalent complexes by electrospray ionization mass spectrometry (2003)

A method for determining the equilibrium association constant of a complexation reaction A + B left harpoon over right harpoon AB by electrospray ionization mass spectrometry is described. The method consists in measuring the relative intensities of the peaks corresponding to A and to AB in equimolar A-B solutions at different concentrations C(0). The results are fitted by a non-linear least-squares procedure, with the two variable parameters being the equilibrium association constant K(a) and a factor R, defined by I(AB)/I(A) = R x [AB]/[A]. The factor R is the ratio between the response factors of AB and A, and corrects for the relative electrospray responses of the complex and the free substrate A, mass discrimination of instrumental origin and/or moderate in-source dissociation. The method is illustrated with the following two systems: complexes between a double-stranded 12-base pair oligonucleotide and minor groove binders, and cyclodextrin complexes with alpha,omega-dicarboxylic acids. For the oligonucleotide complexes, it is found that the response of the complex is not dramatically different to the response of the free oligonucleotide duplex, as the double helix conformation is disturbed by the drug only to a minor extent. In the case of cyclodextrin complexes, these complexes were found to have a much higher response than free cyclodextrin. This may be due to the fact that cyclodextrin is neutral in solution, whereas the complex is charged, but it can also stem from the fact that a significant proportion of the complex is in a non-inclusion geometry. The present method requires the exact determination of the concentrations of the reactants and is applicable to 1 : 1 complexes.
Current Understanding on Aflatoxin Biosynthesis and Future Perspective in Reducing Aflatoxin Contamination (2012)

Traditional molecular techniques have been used in research in discovering the genes and enzymes that are involved in aflatoxin formation and genetic regulation. We cloned most, if not all, of the aflatoxin pathway genes. A consensus gene cluster for aflatoxin biosynthesis was discovered in 2005. The factors that affect aflatoxin formation have been studied. In this report, the author summarized the current status of research progress and future possibilities that may be used for solving aflatoxin contamination.

Noninvasive imaging using an array of electric potential sensors (2006)

We present a design for a linear array of eight electric potential sensors arranged with 1mm spacing and configured to measure spatially varying potential at the microscopic scale. The array successfully detects a 50μm wide feature associated with one of the samples tested. In a single sensor arrangement we have demonstrated &lt;1μm resolution, but the data acquisition times can become prohibitive. The sensors operate noninvasively by capacitively coupling to the sample. The issues associated with using an array of sensors in close proximity are addressed. Cross coupling and strategies for matching the response of the sensors are described in detail. Results are presented for a range of samples including a resistive potential divider, a ceramic microwave circuit board, and a section taken from an oil drill pipe containing a known fault. The data acquisition times are compared with those of a single sensor system, with improvements of 4.5 times in speed reported. In one case real-time simultaneous data acquisition is demonstrated using all eight sensors. Since these sensors operate via the displacement current they may also be applied to the characterization of material properties, including, for example, insulators, dielectrics, and poorly conducting composite materials. It is concluded that we see significant improvements in the data acquisition times for the linear array over a single sensor as expected and are able to overcome the difficulties associated with operating an array of sensors in close proximity.
