Differential aging‐related changes in neurophysiology and gene expression in IB4‐positive and IB4‐negative nociceptive neurons (2018)

Despite pain prevalence altering with age, the effects of aging on the properties of nociceptors are not well understood. Nociceptors, whose somas are located in dorsal root ganglia, are frequently divided into two groups based on their ability to bind isolectin B4 (IB4). Here, using cultured neurons from 1-, 3-, 5-, 8-, 12-, and 18-month-old mice, we investigate age-dependent changes in IB4-positive and IB4-negative neurons. Current-clamp experiments at physiological temperature revealed nonlinear changes in firing frequency of IB4-positive, but not IB4-negative neurons, with a peak at 8 months. This was likely due to the presence of proexcitatory conductances activated at depolarized membrane potentials and significantly higher input resistances found in IB4-positive neurons from 8-month-old mice. Repetitive firing in nociceptors is driven primarily by the TTX-resistant sodium current, and indeed, IB4-positive neurons from 8-month-old mice were found to receive larger contributions from the TTX-resistant window current around the resting membrane potential. To further address the mechanisms behind these differences, we performed RNA-seq experiments on IB4-positive and IB4-negative neurons from 1-, 8-, and 18-month-old mice. We found a larger number of genes significantly affected by age within the IB4-positive than IB4-negative neurons from 8-month-old mice, including known determinants of nociceptor excitability. The above pronounced age-dependent changes at the cellular and molecular levels in IB4-positive neurons point to potential mechanisms behind the reported increase in pain sensitivity in middle-aged rodents and humans, and highlight the possibility of targeting a particular group of neurons in the development of age-tailored pain treatments.
Realizing the Tactile Internet through Intelligent Zero Touch Networks (2022)

The Internet of Things (IoT) is expected to evolve and create numerous technological advances, paving the road for solutions that were once considered impossible. The Tactile Internet (TI), which is envisioned to enable real-time transmission of haptic and conventional data traffic, is creating that paradigm shift towards control-based communication between end-users and machines. Tele-operation, Augmented/Virtual Reality (AR/VR), vehicle platooning, and industrial automation are all applications that can be supported by TI. The realization of TI over Beyond Fifth Generation (B5G) creates challenges for the current wireless communication and networking infrastructure. Network and communication reliability, ultrahigh data rate connectivity, ultra-low latency, and stringent Quality of Service/Experience (QoS/QoE) requirements must all be achieved for TI to effectively operate. Existing network infrastructures that require manual means of management and control cannot accommodate stringent TI constraints. With that said, the adaptation of advanced intelligent and cooperative solutions at the edge of the network is a crucial step towards guaranteed availability of resources and TI services. This article identifies and analyzes some of the technical issues that TI faces, then highlights and proposes potential solutions towards zero touch networks. We pay particular attention to the reliability performance gains achieved from cooperative edge devices, and their role in the provisioning of zero touch networking infrastructures that support TI applications.
Sea Mango Cardiac Intoxication (2008)

Cerbera manghas (sea mango) is one of the poisonous trees belonging to the Apocynaceae family notorious for its cardiac glycoside cardiotoxicity. The tree and the frail of sea mango are easily accessible along the coast of Taiwan. We present a case of a 50-year-old male who attempted suicide by ingesting three seeds of the sea mango. The patient was admitted to the coronary care unit because of complete atrioventricular block, followed by sinus exit block. All conduction abnormalities subsided 3 days later with temporary transcutaneous pacing and supportive treatment. He was discharged with no complications.

Structure and Reactivity of Vinylcyclopropane Radical Cation:  Electron Transfer Photochemistry andab InitioCalculations (1998)

The electron-transfer photochemistry of vinylcyclopropane (1) generates three ring-opened products, 2−4, each bearing a methoxy as well as a 4-cyanophenyl group. The products are ascribed to nucleophilic attack of methanol on the radical cation, 1•+. The attack is regioselective but not regiospecific; attack at the secondary cyclopropane carbons, leading to 2 and trans-3, is preferred; attack at the terminal vinylic carbon, yielding trans-4, occurs to a lesser extent. The potential surface of 1•+ was probed by ab initio calculations; 1•+ has two minima, anti- and syn-1•+; both have Cs symmetry and belong to the unusual structure type with two lengthened cyclopropane bonds. The calculations are in general agreement with the observed reaction pattern.
The Next Linear Collider Test Accelerator's RF Pulse Compression and Transmission Systems (1999)

The overmoded rf transmission and pulsed power compression system for SLAC's Next Linear Collider (NLC) program requires a high degree of transmission efficiency and mode purity to be economically feasible. To this end, a number of new, high power components and systems have been developed at X-band, which transmit rf power in the low loss, circular TE01 mode with negligible mode conversion. In addition, a highly efficient SLED-II* pulse compressor has been developed and successfully tested at high power. The system produced a 200 MW, 250 ns wide pulse with a near-perfect flat-top. In this paper we describe the design and test results of the high power pulse compression system using SLED-II.
3D Scanning Solution for Textured Object using Photometric Stereo with Multiple Known Light Sources (2018)

Photometric Stereo is an efficient image-based 3D reconstruction technique that has been used to reproduce very high-quality reconstructions. However, it faces a couple of limitations: first, one needs to capture images of the 3D scene with different illumination directions. It implies that the 3D scene remains motionless during illumination changes, which prevents the reconstruction of deforming objects. Second, the captured images must be obtained from a single point of view. This leads to depth-map based 2.5D reconstructions, instead of full 3D surfaces. But compared to other 3D imaging methods such as geometry modeling and 3D-scanning, this solution is a valuable tool when examining embossed surfaces where grain texture, carving, deteriorations can be identified. In this paper, we give an outline of Photometric Stereo and provide a case study of our 3D scanner.

Comparison of Ito in young and adult human atrial myocytes: evidence for developmental changes (1995)

In an effort to understand the ionic basis for the developmental changes that have been reported to occur in the configuration of the human atrial action potential, we characterized the transient outward current (Ito) and the inward rectifier current in atrial myocytes isolated from 20 young (ages 1 day-2.5 yr) and 8 adult (11-68 yr) human hearts using the whole cell patch-clamp technique. We found evidence for statistically significant (P < 0.05) age-related changes in the Ito, including 1) the presence of an Ito in only 67% of the cells isolated from young hearts vs. 100% of the cells isolated from adult hearts, 2) an almost twofold increase in the current density of Ito in adult cells vs. young cells, and 3) recovery kinetics that are approximately twofold slower in young myocytes relative to adult myocytes. In contrast, there were no age-related changes found in the current density of the inward rectifier current or the sustained current measured after the decay of Ito. These results suggest important current-dependent changes that occur with age in human atria.

Enhancement of second harmonic generation in chiral metal-organic frameworks with silicon nanoparticles (2017)

Metal-organic frameworks are of interest as a good candidate for fabrication of optical devices with widely tunable optical properties. Improving nonlinear properties and the enhancement of SHG make the route to the usage of MOFs for various applications. We demonstrate at the first time a novel approach for the enhancement of the SHG for MOFs. The approach is consisted in the combination of MOFs and silicon nanoparticles. The maximum 10-fold enhancement is demonstrated. The achieved results paves the way for the application of MOFs as a components of perspective nonlinear organic-inorganic nanophotonic devices.
Pedestrian exposure and the risk of child pedestrian injury (1994)

The authors used data from the New Zealand Household Travel Survey to examine the extent to which children's pedestrian exposure varies with age, sex and household income. Pedestrian injury morbidity data were combined with pedestrian exposure data to examine age-specific pedestrian injury risk. The annual number of road crossings for girls was greater than that for boys. Pedestrian exposure increased with increasing age. Children aged 5-9 years in the lowest household income bracket crossed approximately 50% more roads than those in the middle and upper income brackets. However, for children aged 10-14 years there was little variation with household income. Sex differences in pedestrian injury rates cannot be explained by differences in exposure although increased exposure may partly explain the increased injury rates for children in lower socio-economic groups. Prevention strategies might aim to reduce pedestrian exposure for alternatively to reduce pedestrian injury risk per unit of exposure by making safer urban living environments.

Optical trap activation in a photorefractive polymer (1994)

Optical trap activation has been observed to increase the steady-state diffraction efficiency by a factor of 3 in a photorefractive (PR) polymer, poly(methylmethacrylate):(l,3-dimethyl-2,2-tetramethylene-5-nitrobenzimidazoline):C60 (PMMA:DTNBI:C60). The increased diffraction efficiency is accompanied by an increase in the PR storage lifetime but also by an increase in the characteristic grating growth time of the PR grating. The optical activation of the deep trapping sites is observed to be a sublinear function of the optical irradiation power. Both spatially uniform trap activation and spatial patterning of the photorefractive response of the material are demonstrated.
Internet Chat as Collaborative CALL: Language learning strategies in an Internet Chat class (2005)

This paper describes an internet Chat class in a compulsory Japanese language subject at an Australian university. The study seeks evidence of the use of language strategies relating to social interaction in Chat classes and examines the importance of strategy use in this form of Collaborative CALL. It also presents the way the medium is used in the curriculum as a means of fostering student collaboration. A preliminary survey was conducted to investigate types of strategies used by the students in two specific situations: when they saw an unknown word in their Chat partner s message and when they did not know how to say a particular word. The results demonstrate how students practise the social strategies necessary for collaborative learning through a CALL activity. This is followed by a discussion of the importance and role of social learning strategies in collaborative CALL and possible directions of future studies on internet Chat use in foreign language education.
KOH Based Method for the Determination of Oxygen Content in Ball Milled SiOx Material (2021)

SiO x is a silicon-based anode material for Li-ion batteries that has a high specific capacity and good cycle life. Lithiation of SiO x results in the formation of active Si cores surrounded by an inactive stabilizing matrix of irreversible lithium silicates and lithium oxides. SiO x with adjustable values of x can be synthesized by roller milling under oxygen flow, with the oxygen content being controlled by the amount of time spent milling in oxygen vs milling under argon. A fast and inexpensive oxygen content determination method was needed for determination of the oxygen content in SiO x as the roller milling process proceeded. A simple 4-step procedure to determine the oxygen content in SiO x is presented using a KOH solution, aluminized pouch bags, and Archimedes gas quantification measurements. This method can serve as a quick and inexpensive substitute to traditional oxygen content determination measurements such as gas fusion analysis.
Treadmill exercise within lower-body negative pressure attenuates simulated spaceflight-induced reductions of balance abilities in men but not women (2016)

Spaceflight causes sensorimotor adaptations that result in balance deficiencies on return to a gravitational environment. Treadmill exercise within lower-body negative pressure (LBNP) helps protect physiological function during microgravity as simulated by bed rest. Therefore, we hypothesized that treadmill exercise within LBNP would prevent balance losses in both male and female identical twins during 30 days of 6° head-down tilt bed rest. Fifteen (seven female and eight male) identical twin sets participated in this simulation of microgravity. Within each twin pair, one twin was randomly assigned to an exercise group that performed 40 min of supine treadmill exercise within LBNP set to generate 1.0-1.2 body weight, followed by 5 min of static feet-supported LBNP, 6 days per week. Their identical sibling was assigned to a non-exercise control group with all other bed rest conditions equivalent. Before and immediately after bed rest, subjects completed standing and walking rail balance tests with eyes open and eyes closed. In control subjects, standing rail balance times (men: -42%, women: -40%), rail walk distances (men: -44%, women: -32%) and rail walk times (men: -34%, women: -31%) significantly decreased after bed rest. Compared with controls, treadmill exercise within LBNP significantly attenuated losses of standing rail balance time by 63% in men, but the 41% attenuation in women was not significant. Treadmill exercise within LBNP did not affect rail walk abilities in men or women. Treadmill exercise within LBNP during simulated spaceflight attenuates loss of balance control in men but not in women.
Photodynamic Inactivation of Enteroviruses (1965)

Wallis, Craig (Baylor University College of Medicine, Houston, Tex.), and Joseph L. Melnick. Photodynamic inactivation of enteroviruses. J. Bacteriol. 89:41-46. 1965.-Enteroviruses are usually resistant to photodynamic inactivation, but they can be rendered completely photosensitive to proflavine at pH 9 to 10, if they are first purified by filtration through an anion resin. In addition, if enteroviruses are grown in cells maintained in a salt-glucose medium, they can be photosensitized. Of 38 enteroviruses tested, 10 were rendered completely photosensitive to proflavine, or toluidine blue, or both, and the remaining 28 viruses were sensitized, but to a lesser degree. The binding of dye to the virus can be reversed by lowering the pH.
Racial Differences in the Cause-Specific Prevalence of Blindness in East Baltimore (1991)

The pattern of blindness in urban Baltimore appears to be different among blacks and whites. Whites are far more likely to have age-related macular degeneration, and blacks to have primary open-angle glaucoma. The high rate of unoperated cataracts among younger blacks and among elderly subjects of both races suggests that health services are underused. Half of all blindness in this urban population is probably preventable or reversible.
Smart helmet: Monitoring brain, cardiac and respiratory activity (2015)

The timing of the assessment of the injuries following a road-traffic accident involving motorcyclists is absolutely crucial, particularly in the events with head trauma. Standard apparatus for monitoring cardiac activity is usually attached to the limbs or the torso, while the brain function is routinely measured with a separate unit connected to the head-mounted sensors. In stark contrast to these, we propose an integrated system which incorporates the two functionalities inside an ordinary motorcycle helmet. Multiple fabric electrodes were mounted inside the helmet at positions featuring good contact with the skin at different sections of the head. The experimental results demonstrate that the R-peaks (and therefore the heart rate) can be reliably extracted from potentials measured with electrodes on the mastoids and the lower jaw, while the electrodes on the forehead enable the observation of neural signals. We conclude that various vital sings and brain activity can be readily recorded from the inside of a helmet in a comfortable and inconspicuous way, requiring only a negligible setup effort.

Applications of 3D elastic wavefield simulation to induced seismicity (2016)

Understanding the potential ground motions associated with induced seismicity is a key requirement for conducting hazard and risk assessment. 3D elastic wavefield simulation, normally used in industry for imaging or full-wavefield inversion applications, is used here to gain insight to wavefield effects important to induced seismicity studies. Detailed 3D seismic velocity models developed for active-source seismic imaging can be used to understand field-specific ground motion behaviors. Source mechanism and rupture geometry effects are explored, with emphasis on how hypocenter-to-surface path effects are influenced by structure and stratigraphy. Ground motion prediction for induced seismicity may benefit from wavefield simulations when near-epicenter or higher-magnitude data are incomplete.

Enhanced external quantum efficiency of III-nitride micro-light-emitting diodes using vertical and transparent package (2021)

Abstract In this work, 40 × 40 μ m 2 blue InGaN micro-light-emitting diodes ( μ LEDs) with transparent and vertical package was first demonstrated by using either double-side polished zinc oxide (ZnO) or sapphire substrate as a transparent submount. The performance of the vertical and conventional packages was compared, where the devices packaged vertically resulted in smaller blueshift in peak wavelength with increasing drive current due to the higher junction temperature. Moreover, devices packaged vertically with the sapphire submount offered 19% and 32% greater light output power at 20 and 100 A cm −2 , respectively, and 18% improvement in maximum external quantum efficiency (EQE) than devices with conventional package. Finally, the peak EQE of 58% was achieved from the μ LED packaged vertically using a sapphire submount.

Winterized Methyl Esters from Soybean Oil:An Alternative Diesel Fuel With Improved Low-Temperature Flow Properties (1997)

&lt;div class="htmlview paragraph"&gt;Methyl esters from vegetable oils (biodiesel) are very attractive as alternative fuels for combustion in direct injection compression-ignition (diesel) engines. Biodiesel fuels have low-temperature flow properties that limit utilization during cooler weather in moderate temperature climates. Although winterization reduces the cloud point (CP) of methyl soyate from 0 to -2O°C, liquid product yields were relatively low (0.30-0.33 g/g). Winterization of methyl soyate-cold flow improver mixtures decreased CP by -11°C and increased yields to 0.80-0.87 g/g. Winterization of methyl soyate from hexane and isopropanol solvents gave similar results. Differential scanning calorimetry (DSC) analyses showed that nucleation mechanisms of methyl esters were significantly affected by winterization.&lt;/div&gt;
Semantic-based Approach to Context Management in Ubiquitous Environment (2017)

Context-aware applications need to react and adapt to changes in their computing environment, which is in general ubiquitous and inherently distributed. Therefore, the context communication faces the problem of context representations heterogeneity, the limitation of devices capacity and network bandwidth. In order to overcome this challenging issue, a particular management of the context is required either for its collection, update, and exchange. In this paper, we propose an approach to manage the context in ubiquitous environments based on the semantic representation of the context and its update using standard languages such as RDF and RDF(s). Our proposed approach provides the simplicity and flexibility that allow the developer to express the context without the need for a unified context model. The results of the experimentation carried out using a prototype implementation of a middleware supports the proposed approach, are in favour of using our approach in the case of resource-constrained devices and network.
