Separation properties of alcohol-water mixture through silicalite-I-filled silicone rubber membranes by pervaporation (1998)

The structure and the adsorption-desorption properties of zeolite silicalite- I by different treatments after synthesis were studied. The pervaporation properties of the alcohol-water mixture through silicone rubber filled with zeolite silicalite-I by different treatments were also investigated. Treating silicalite-I by acid or/and under steam was found to eliminate the metallic impurities in the zeolite and to perfect the crystalline structure of the zeolite. After treatment, silicalite-I is more selective to alcohol and the desorption of the alcohol from the zeolite is also easier. The silicone rubber membrane filled with treated silicalite-I shows a high performance for alcohol extraction from the dilute aqueous solution by pervaporation. The separation factor of the poly(dimethyl siloxane) (PDMS) membrane filled with silicalite-I treated succes- sively by acid and steam is about 30 when the ethanol content in the feed is 5 wt % at 507C. q 1998 John Wiley & Sons, Inc.

The spine neck filters membrane potentials (2006)

Dendritic spines receive most synaptic inputs in the forebrain. Their morphology, with a spine head isolated from the dendrite by a slender neck, indicates a potential role in isolating inputs. Indeed, biochemical compartmentalization occurs at spine heads because of the diffusional bottleneck created by the spine neck. Here we investigate whether the spine neck also isolates inputs electrically. Using two-photon uncaging of glutamate on spine heads from mouse layer-5 neocortical pyramidal cells, we find that the amplitude of uncaging potentials at the soma is inversely proportional to neck length. This effect is strong and independent of the position of the spine in the dendritic tree and size of the spine head. Moreover, spines with long necks are electrically silent at the soma, although their heads are activated by the uncaging event, as determined with calcium imaging. Finally, second harmonic measurements of membrane potential reveal an attenuation of somatic voltages into the spine head, an attenuation directly proportional to neck length. We conclude that the spine neck plays an electrical role in the transmission of membrane potentials, isolating synapses electrically.
A robot in the family (2014)

The robot seems determined to put a bigger smile on the man's face. "Are you smiling from the bottom of your heart?" it asks. The man chuckles. "That's what I'm talking about," the robot quips in a high-pitched voice. Then, just for good measure, it bows its plastic head and apologizes for being "too bossy to our CEO."
Textile Concentric Ring Electrodes for ECG Recording Based on Screen-Printing Technology (2018)

Among many of the electrode designs used in electrocardiography (ECG), concentric ring electrodes (CREs) are one of the most promising due to their enhanced spatial resolution. Their development has undergone a great push due to their use in recent years; however, they are not yet widely used in clinical practice. CRE implementation in textiles will lead to a low cost, flexible, comfortable, and robust electrode capable of detecting high spatial resolution ECG signals. A textile CRE set has been designed and developed using screen-printing technology. This is a mature technology in the textile industry and, therefore, does not require heavy investments. Inks employed as conductive elements have been silver and a conducting polymer (poly (3,4-ethylenedioxythiophene) polystyrene sulfonate; PEDOT:PSS). Conducting polymers have biocompatibility advantages, they can be used with flexible substrates, and they are available for several printing technologies. CREs implemented with both inks have been compared by analyzing their electric features and their performance in detecting ECG signals. The results reveal that silver CREs present a higher average thickness and slightly lower skin-electrode impedance than PEDOT:PSS CREs. As for ECG recordings with subjects at rest, both CREs allowed the uptake of bipolar concentric ECG signals (BC-ECG) with signal-to-noise ratios similar to that of conventional ECG recordings. Regarding the saturation and alterations of ECGs captured with textile CREs caused by intentional subject movements, silver CREs presented a more stable response (fewer saturations and alterations) than those of PEDOT:PSS. Moreover, BC-ECG signals provided higher spatial resolution compared to conventional ECG. This improved spatial resolution was manifested in the identification of P1 and P2 waves of atrial activity in most of the BC-ECG signals. It can be concluded that textile silver CREs are more suitable than those of PEDOT:PSS for obtaining BC-ECG records. These developed textile electrodes bring the use of CREs closer to the clinical environment.
Cloud-Assisted Dynamic Content Sharing among Vehicles (2016)

In this paper, we propose a method to share dynamic contents such as short video clips created by vehicles' mounted cameras. In these days, many vehicles are equipped with driving recorders and other sensors to detect surrounding situations. Such cameras and sensors can work as real-time monitors of traffic conditions and other dynamic environments such as road situations. Such information should be shared by neighboring vehicles for safer driving. For this purpose, we take a hybrid approach where we use V2V communication and V2I communication via cellular networks to realize cloud-assisted, V2V-based dynamic content sharing. The key idea is that the cloud server only collects the vehicles' coordinates periodically and determines a content exchange schedule that maximizes the utilization of V2V communication and minimizes the cost of cellular communication, keeping reasonable delivery ratios. This is based on the mobility estimation of vehicles and DTN-based content delivery. Through extensive simulations, we show that our method can reduce cellular network traffic volume, while keeping reasonable delivery ratios.
Characteristic and critical excitation length scales in 1-D and 2-D simulations of reentrant cardiac arrhythmias using simple two-variable models. (1999)

We discuss major characteristic lengths as the lumped parameters characterizing kinematics and dynamics of excitation waves in idealized one- and two-dimensional myocardium. First we consider the directional dependence of the length scale in the anisotropic bi- and monodomain myocardium. Next, we show that there is a well-defined smallness parameter that allows one to consider the monodomain equations as the first approximation to the bidomain theory. Then we use this approximation and turn our attention to the dynamics and to finding the major physiologic parameters governing such transient processes as the formation of a reentrant wave and its subsequent degradation into the malignant cardiac arrhythmia--ventricular fibrillation. It appears that in both the one- and two-dimensional cases the stability of a reentrant periodic process (representing a VT rhythm) is determined by the same two physiologic parameters: the wave width lambda, which is approximately the size of depolarized zone, and ratio of lambda to the critical length L(h)cr, which is defined as the wave width of an action potential propagating with the minimum possible speed. The parameter L(h)cr determines the length scale (size) of an ectopic region that may initiate a wave. It also determines the duration of the vulnerable window for initiating the unidirectional block as well as a minimum permissible length of the reentrant circuit. We also present some evidence that depending on the value of lambda the waveforms of the simulated ECGs for reentrant activity vary from monomorphic to polymorphic.

A new competitive fluorescence immunoassay for detection of Listeria monocytogenes (2012)

A new competitive immunoassay has been designed using a specific monoclonal antibody labeled with a fluorophore. A specific and highly conserved peptide of 11 amino acids from the protein p60 of L. monocytogenes has been synthesised and used for the production of a monoclonal anti-p60. This antibody was used in the conception of a detection test able to detect 1 CFU of L. monocytogenes after only 18 hours of incubation with a minimum of manipulation. The test is based on a competition principle between the recombinant p60 protein and the p60 from L. monocytogenes present in the sample. A column containing a sepharose matrix was used to immobilize the recombinant p60 protein and the labeled monoclonal antibody, which is captured by the p60 from the sample when added to the column. An increase of the fluorescence signal of the eluate means a positive result. No cross-reactivity was observed with non-pathogenic Listeria species and each serotype of L. monocytogenes can be detected whereas some other immunological methods show cross-reactivity and false negative.
Highly Diastereo- and Enantioselective Synthesis of Trifluoromethyl-Substituted Cyclopropanes via Myoglobin-Catalyzed Transfer of Trifluoromethylcarbene (2017)

We report an efficient strategy for the asymmetric synthesis of trifluoromethyl-substituted cyclopropanes by means of myoglobin-catalyzed olefin cyclopropanation reactions in the presence of 2-diazo-1,1,1-trifluoroethane (CF<sub>3</sub>CHN<sub>2</sub>) as the carbene donor. These transformations were realized using a two-compartment setup in which ex situ generated gaseous CF<sub>3</sub>CHN<sub>2</sub> is processed by engineered myoglobin catalysts expressed in bacterial cells. This approach was successfully applied to afford a variety of trans-1-trifluoromethyl-2-arylcyclopropanes in high yields (61-99%) and excellent diastereo- and enantioselectivity (97-99.9% de and ee). Furthermore, mirror-image forms of these products could be obtained using myoglobin variants featuring stereodivergent selectivity. These reactions provide a convenient and effective biocatalytic route to the stereoselective synthesis of key fluorinated building blocks of high value for medicinal chemistry and drug discovery. This work expands the range of carbene-mediated transformations accessible via metalloprotein catalysts and introduces a potentially general strategy for exploiting gaseous and/or hard-to-handle carbene donor reagents in biocatalytic carbene transfer reactions.
Increasing the Cell Density in SCP Production from Cellulosic Substrtaes (1979)

Undigested cellulosic substrate was frequently replaced with new substrate during fermentation. About 3-fold increase in cell density could be obtained by changing the substrate.
Research on a multi-agent based group awareness model (2012)

Based on the research background of group awareness theory and the research achievement of agent technology, this paper applies multi-agent technology in Computer- Supported Cooperative Work (CSCW) environment and describes the group awareness in CSCW system with the multi-agent based group awareness model. It builds up the multi-agent based group awareness model and discusses its key problems with emphasis on how to achieve the collaboration awareness in the CSCW system through the cooperation and interaction among the three types of agents – management agent, interactive agent and function agent. These agents exchange information or invoke others in the CSCW system and the final of that is proved to be more accurate and flexible in describing the dynamic process and regularities of tasks, roles and actions in real life.
Building and road detection from large aerial imagery (2015)

Building and road detection from aerial imagery has many applications in a wide range of areas including urban design, real-estate management, and disaster relief. The extracting buildings and roads from aerial imagery has been performed by human experts manually, so that it has been very costly and time-consuming process. Our goal is to develop a system for automatically detecting buildings and roads directly from aerial imagery. Many attempts at automatic aerial imagery interpretation have been proposed in remote sensing literature, but much of early works use local features to classify each pixel or segment to an object label, so that these kind of approach needs some prior knowledge on object appearance or class-conditional distribution of pixel values. Furthermore, some works also need a segmentation step as pre-processing. Therefore, we use Convolutional Neural Networks(CNN) to learn mapping from raw pixel values in aerial imagery to three object labels (buildings, roads, and others), in other words, we generate three-channel maps from raw aerial imagery input. We take a patch-based semantic segmentation approach, so we firstly divide large aerial imagery into small patches and then train the CNN with those patches and corresponding three-channel map patches. Finally, we evaluate our system on a large-scale road and building detection datasets that is publicly available.
PROPERTIES OF FLUORIDE-RELEASING RESIN COMPOSITE RESTORATIVE MATERIALS (2008)

The objectives of this study were to examine the properties of fluoride-releasing resin composite restorative materials. Four commercially available compomer materials (Compoglass F: CF, AP: DA, flow: DF, F2000: FT) and one fluoride-releasing composite resin ( Ceram: TC) were selected as experimental materials. Rectangular-shaped tensile test specimens were fabricated in a teflon mold giving 5mm in gauge length and 2mm in thickness. Disk-shaped specimens were fabricated in the split teflon mold with diameter of 15mm and thickness of 1mm. After curing for an hour, specimens were immersed in deionized water at for 30 days. All specimens were thermocycled for 10,000 cycles with 15 seconds of dwelling time in each and water baths. Toothbrush abrasion test was conducted under a load of 1.5 N and the abraded surfaces were examined with surface roughness tester (SV-3000, Mitutoyo Co, Japan) and SEM (JSM-5800, JEOL, Japan). Fluoride recharging was done by toothbrushing for 3 min. using a fluoride toothpaste (Perio Alpine Herb, LG Household & Health Care, Korea). The results obtained were summarized as follows; 1. The highest tensile strength value of 32.3 MPa was observed in TC group and the lowest value of 16.8 MPa was observed in CF group. The tensile strength of TC group was significantly higher than those of CF and DF groups (P in CF group and the lowest value was in TC group. The amount of fluoride release of CF group was significantly higher than other groups (P
Antidepressant Interactions with the NMDA NR1-1b Subunit (2008)

The targets for tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and selective norepinephrine reuptake inhibitors (SNRIs) are known to be the serotonin and norepinephrine transport (reuptake) proteins which are embedded in presynaptic nerve terminals and function to bring these neurotransmitters from the synaptic cleft back into the presynaptic neuron. Using a combination of intrinsic and extrinsic fluorescence quenching, Stern-Volmer analysis, and protease protection assays, we have shown that therapeutics from each of these three classes of antidepressants bind to the extracellular S1S2 domain of the NR1-1b subunit of the NMDA receptor. These results are in agreement with recent work from our lab demonstrating the interaction of antidepressants with the S1S2 domain of the GluR2 subunit of the AMPA receptor, another member of the ionotropic glutamate receptor subfamily, as well as work from other labs, and continue the discussion of the involvement of ionotropic glutamate receptors in depression.
Isolation and Characterization of Oligosaccharides from Honey. Part II. Trisaccharides (1968)

SummaryThe trisaccharides melezitose, 3-α-isomaltosylglucose and maltotriose were isolated from honey and characterized as crystalline β-hendecaacetates; 1-kestose and panose as the crystalline sugars and isomaltotriose as the crystalline β-undecabenzoate. Erlose and theanderose (6G-α-glucosylsucrose) were identified by the isolation and characterization of the disaccharides derived on partial hydrolyses. Isopanose, isomaltotetraose and isomaltopentaose were identified by their specific optical rotations and behaviour to acid and enzymic hydrolysis. Evidence is also presented for the presence in honey of two new trisaccharides, namely 2-α-maltosylglucose or 4-α-kojibiosylglucose and the linear 4-α-gentiobiosylglucose. The approximate quantitative composition of these sugars is presented.
Changing Patterns in Tibial Fractures Resulting from Skiing (1987)

Of the 734 adult tibial fractures treated in Aspen, Colorado, from 1968-1978, follow-up results were obtained on 527 (72%). The fractures were analyzed with regard to rate of healing, age of patient, and location of fractures. There was a statistically significant increase in healing time with increasing age between ages 16-40. The location of tibial fracture (proximal, middle, distal) had no significant influence on rate of healing. The occurrence of open tibial fracture was low (3% of total) and in most instances wounds were benign (Class I). Compartment syndrome is rarely encountered in skiing fracture because of the relatively low energy involved. All tibial fractures occurring between 1982-1984 were reviewed and compared to the earlier series. This comparison confirmed the continual overall decline in rate of tibial fracture from skiing (from 12.9/100,000 skier days in 1968 to 2.9/100,000 skier days in 1983). This decline was primarily in spiral fractures (from 70% of total in 1968 to 50% in 1983). The percent of transverse fractures was unchanged (+/- 15%) while the percent of short oblique fractures increased from 11% to 33%. Properly adjusted and maintained safety equipment afforded reasonable protection from spiral fractures of the tibia, but a conceptual departure from the current release binding design would be required to protect against the benign moments that produced transverse and short oblique fracture. The current treatment philosophy is based on fracture type and the availability or experience with newer treatment modes.

Polarized Electroluminescence from Rubbing-Aligned Poly(p-phenylenevinylene) (1999)

Organic light-emitting diodes (OLEDs) that emit polarized light are useful for liquid crystal display applications. Here rubbing alignment of a segmented precursor poly(p-phenylenevinylene) (PPV) is used for the preparation of two-layer LEDs that show high dichroic ratios of linearly polarized electroluminescence. The Figure is a scanning electron micrograph of the rubbed PPV layer.
Three-Dimensional Printing of Nanoscale Powders Using Laser Shockwaves (2015)

A new three-dimensional (3D) printing process designated as shockwave-induced freeform technique (SWIFT) is explored for fabricating microparts from nanopowders. SWIFT consists of generating shockwaves using a laser beam, applying these shocks to pressure sinter nanoparticles at room temperature, and creating structures and devices by the traditional layer-by-layer formation. Shockwave cold compaction of nanoscale powders has the capability to overcome limitations, such as shrinkage, porosity, rough surface, and wide tolerance, normally encountered in hot sintering processes, such as selective laser sintering. In this study, the window of operating parameters and the underlying physics of SWIFT were investigated using a high-energy Q-switched Nd: YAG laser and nanodiamond (ND) powders. Results indicate the potential of SWIFT for fabricating high-performance diamond microtools with high aspect ratios, smooth surfaces, and sharp edges. The drawback is that the SWIFT process does not work for micro-sized powders.
Evaluation method for heart failure using RR sequence normalized histogram (2011)

Histogram and scatter plot are important graphical indices for heart rate variability (HRV) analysis. However, they are difficult to quantify the complexity for time series and have little specificity to some cardiovascular diseases. This paper proposed a new graphical method for HRV analysis, which was named as RR sequence normalized histogram. Based on the analysis of RR sequence normalized histogram, three quantitative indices were defined: center-edge ratio (CER), cumulative energy (CE) and range information entropy (RIEn). To verify the validity of the new method, a total of 120 subjects (60 heart failure subjects and 60 healthy control subjects) were enrolled and the three indices were calculated respectively. A Wilcoxon rank sum test showed that: CER (p = 0.232) and CE (p = 0.417) had no statistical differences between heart failure and healthy control group while RIEn (p = 0.027) had. This indicated that the new method had a potential application in evaluating the heart failure and the index RIEn had a better effectiveness than the other two indices.
