Synthesis, Structure, and Pressure-Induced Polymerization of Li3Fe(CN)6 Accompanied with Enhanced Conductivity (2015)

Pressure-induced polymerization of charged triple-bond monomers like acetylide and cyanide could lead to formation of a conductive metal-carbon network composite, thus providing a new route to synthesize inorganic/organic conductors with tunable composition and properties. The industry application of this promising synthetic method is mainly limited by the reaction pressure needed, which is often too high to be reached for gram amounts of sample. Here we successfully synthesized highly conductive Li3Fe(CN)6 at maximum pressure around 5 GPa and used in situ diagnostic tools to follow the structural and functional transformations of the sample, including in situ X-ray and neutron diffraction and Raman and impedance spectroscopy, along with the neutron pair distribution function measurement on the recovered sample. The cyanide anions start to react around 1 GPa and bond to each other irreversibly at around 5 GPa, which are the lowest reaction pressures in all known metal cyanides and within the technologically achievable pressure range for industrial production. The conductivity of the polymer is above 10(-3) S · cm(-1), which reaches the range of conductive polymers. This investigation suggests that the pressure-induced polymerization route is practicable for synthesizing some types of functional conductive materials for industrial use, and further research like doping and heating can hence be motivated to synthesize novel materials under lower pressure and with better performances.

Distribution of the α7 nicotinic acetylcholine receptor subunit in the developing chick cerebellum (1998)

Previous studies of the nicotinic acetylcholine receptor (nAChR) subunits in adult mammalian and avian brains have demonstrated a spatially restricted distribution of these subunits; little, however, is known about the nAChR subunit developmental distribution. The present study demonstrated a transient pattern of distribution of the neuronal nAChR subunit, alpha7, in the developing chick cerebellum by using immunohistochemical techniques. This transient distribution may suggest a critical period for the development of the cholinergic system in the cerebellum.
Diaspirin Crosslinked Hemoglobin (DCLHbTM): Characterization of the Process and the Product Manufactured Under GMP Requirements for Clinical Studies (1994)

Initiation of Clinical Trials in 1992 necessitated product manufacture under FDA Good Manufacturing Practice (GMP) requirements. To this end, all product components used were characterized to meet established requirements and processes and analytical methods were validated to confirm and document their utility and reproductibility. Manufacture of multiple 50+ liter lots of 10%g DCLHb under GMP requirements resulted in a pure and homogeneous product which reproducibly met a rigorous and complete set of product specifications. Final release testing of five consecutive GMP lots showed hemoglobin concentrations of 10.2 +/- 0.2g%, pH of 7.33 +/- 0.02 (37 degrees C), methemoglobin concentrations of 3.2 +/- 0.6%, degree of crosslinking of 99.8 +/- 0.1% and a P50 of 32.4 +/- 1.0 mmHg (37 degrees C). The mean overall yield for production of these five lots was 55 +/- 2%. Products were all endotoxin free as indicated by rabbit, cytokine and LAL testing (< 0.06 EU/mL); a critical characteristic for a molecule which may bind endotoxin. All lots were sterile as indicated by compendial testing.
Development of accelerated aging test for ESD/EMI protective materials and electrical discontinuity at seams and interconnections (2003)

Many studies of new protective ESD/EMI materials, such as antistats, and conductive members of a seam or interconnection, such as metals that make up corrodible seams and interconnections, should be regarded as incomplete. Little or no attention has been paid to changes in essential material properties exposed to various environments because the test takes too much time. A procedure for development of accelerated tests is described. There are a number of variables that can be used to reduce the time usually required for accelerated aging tests. These variables include, but are not limited to, temperature, percent relative humidity, mechanical and electrical properties. Examples from the literature are cited to show how temperature can be used to develop acceleration factors to reduce the time for aging in outgassing and resistivity aging. Corrosion reactions can degrade the ESD/EMI protected product by promoting electromagnetic emissions and also producing electrical discontinuity at seams (EDS) and interconnections (EDI). EDS can result in secondary ESD events. EDI can result in circuit malfunctioning. Under these conditions, temperature can be used to produce large acceleration factors, thus reducing the time to simulate the lifetime aging process of the electronic product.
An ABC Transporter Mutation Alters Root Exudation of Phytochemicals That Provoke an Overhaul of Natural (2009)

Root exudates influence the surrounding soil microbial community, and recent evidence demonstrates the involvement of ATPbinding cassette (ABC) transporters in root secretion of phytochemicals. In this study, we examined effects of seven Arabidopsis (Arabidopsis thaliana) ABC transporter mutants on the microbial community in native soils. After two generations, only the Arabidopsis abcg30 (Atpdr2) mutant had significantly altered both the fungal and bacterial communities compared with the wild type using automated ribosomal intergenic spacer analysis. Similarly, root exudate profiles differed between the mutants; however, the largest variance from the wild type (Columbia-0) was observed in abcg30, which showed increased phenolics and decreased sugars. In support of this biochemical observation, whole-genome expression analyses of abcg30 roots revealed that some genes involved in biosynthesis and transport of secondary metabolites were up-regulated, while some sugar transporters were down-regulated compared with genome expression in wild-type roots. Microbial taxa associated with Columbia-0 and abcg30 cultured soils determined by pyrosequencing revealed that exudates from abcg30 cultivated a microbial community with a relatively greater abundance of potentially beneficial bacteria (i.e. plant-growth-promoting rhizobacteria and nitrogen fixers) and were specifically enriched in bacteria involved in heavy metal remediation. In summary, we report how a single gene mutation from a functional plant mutant influences the surrounding community of soil organisms, showing that genes are not only important for intrinsic plant physiology but also for the interactions with the surrounding community of organisms as well.
Morphologic Variations of the Fibular Malleolar Groove with Recurrent Dislocation of the Peroneal Tendons (2009)

This study demonstrated that no significant difference could be detected in the morphological shape of the fibular malleolar groove between patients with and without dislocation of the peroneal tendons.
Smectic liquid crystal tunable filters (1991)

Abstract Tunable filters, capable of spectral discrimination, have applications in optical sensing and signal processing, wavelength division multiplexing and demultiplexing, colorimetry and color displays. In this paper we present results on the design and fabrication of a new class of tunable filters, which employ smectic A electroclinic and smectic C ferroelectric liquid crystals (FLC's). The first FLC tunable filter demonstrated used binary smectic C material in a Lyot filter geometry to switch discretely between two wavelengths at 440 nm and 660 nm, with 50 nm resolution. A second filter has been designed and demonstrated using smectic A electroclinic materials to continuously tune over one hundred nanometers in the visible. Computer simulations and experimental results on these filter designs will be presented.

Essential role of the nonreducing terminal α‐mannosyl residues of the N‐linked carbohydrate chain of bovine zona pellucida glycoproteins in sperm‐egg binding (2001)

It has been proposed that mammalian sperm bind species-specifically to carbohydrate chains of zona pellucida glycoproteins at fertilization. Although the sperm ligand carbohydrate chains have been characterized in mice and pigs, the existence of the ligands of other mammals remains unclear. In order to explore the bovine sperm ligand, two in vitro competition assay methods were applied. As a result, a high-mannose-type carbohydrate chain, Manalpha1-6(Manalpha1-3)Manalpha1-6(Manalpha1-3)Manbeta1-4GlcNAcbeta1-4GlcNAc, which is the major neutral chain in bovine egg zona glycoproteins, was shown to possess bovine sperm ligand activity. When nonreducing terminal alpha-mannosyl residues were eliminated from the zona glycoproteins by alpha-mannosidase digestion, the ligand activity was reduced, indicating that the alpha-mannosyl residues play an essential role in bovine sperm-egg binding. The number of sperm binding to eggs was reduced to about one-half after fertilization. The ligand-active high-mannose-type chain may be buried after fertilization, since its amount remains unchanged. Pretreatment of bovine sperm with the sperm ligand-carbohydrate chain significantly inhibited penetration of the sperm into oocyte and the male pronucleus formation. Thus, a correlation between the sperm ligand activity and in vitro fertilization rate was observed.
Invulnerability Simulation of Urban Agglomeration Passenger Transport Network under Incomplete Information Attack Strategy (2021)

This paper explores the invulnerability of urban agglomeration transportation network under the incomplete information attack strategy. This approach employed the site mapping method to construct the urban agglomeration composite transportation network model, and the network is weighted based on the actual passenger flow. Then the nodes are defined according to the overload conditions. In addition, based on the capacity‐load model, the cascading failure model of the urban agglomeration passenger transport network is constructed, and the incomplete information attack strategy and network invulnerability measure index are determined. Finally, the case of Hu‐Bao‐E‐Yu urban agglomeration is simulated to quantify the effects of attack strategies with varied information level, node load factors, and capacity weight and distance weight of the residual connected edge. The results reveal that the network crash speed is positively related to the information span of the attacker unless the information span exceeds 0.9 or accuracy exceeds 0.6. When the information span is low, the information accuracy δ has a critical impact on the network crash speed. Moreover, in the presence of attack, high or low values of node load factor are conducive to the improvement of network invulnerability. As a scale‐free network, urban agglomeration transportation network shows strong robustness to random attacks and exhibits vulnerability to deliberate attacks. The capacity weight value α and distance weight value β of residual connected edge have different effects on the network invulnerability under different information span strategies.

An Algorithm for Discovering Physical Topology in Single Subnet IP Networks (2005)

In this paper, we present a novel algorithm for discovering physical topology in heterogeneous (i.e. multi-vendor) single subnet IP networks. Our algorithm is based on standard SNMP MIB information that is widely supported by modern IP network elements. Algorithm resorts to the port's traffic when AFT information is insufficient. Simulation and analysis results show that this algorithm can discover the physical network topology accurately even if SNMP is not supported by some network elements.
Photothermal ablation is the primary mechanism in holmium:YAG laser lithotripsy of urinary calculi (1999)

Because of the &gt;= 250 microsecond(s) pulsewidth emitted by the Ho:YAG laser used in clinical lithotripsy, it is unlikely that stress confinement occurs within the irradiated stones. Experimental data supports a thermal mechanism for Ho:YAG laser stone ablation. Previous work has shown that stone fragmentation occurs soon after the onset of the laser pulse, is uncorrelated to cavitation bubble formation or collapse, and is associated with low pressures. Moreover, lithotripsy proceeds fastest with desiccated stones in air (data based on laser ablation of calcium oxalate monohydrate stones), indicating that direct absorption of the laser radiation by the stone material is required for the most efficient ablation. Lowering the initial temperature of calculi reduces the stone mass-loss following 20 J of delivered laser energy: 2.2 +/- 1.1 mg vs 5.2 +/- 1.6 mg for calcium oxalate monohydrate (COM) stones (-80 vs 23 degree(s)C), and 0.8 +/- 0.4 mg vs 2.2 +/- 1.1 mg for cystine stones (-80 vs 23 degree(s)C), p &lt;EQ 0.5. In all of the stone compositions examined, thermal breakdown products have been detected, e.g. CaCO<SUB>3</SUB> from COM; free sulfur and cysteine from cystine; Ca<SUB>2</SUB>O<SUB>7</SUB>P<SUB>2</SUB> from calcium hydrogen phosphate dihydrate, and cyanide and alloxan from uric acid. All of these observations are most consistent with a photothermal breakdown process induced by Ho:YAG laser lithotripsy.

Rapid Salmonella detection using an acoustic wave device combined with the RCA isothermal DNA amplification method (2016)

Salmonella enterica serovar Typhimurium is a major foodborne pathogen that causes Salmonellosis, posing a serious threat for public health and economy; thus, the development of fast and sensitive methods is of paramount importance for food quality control and safety management. In the current work, we are presenting a new approach where an isothermal amplification method is combined with an acoustic wave device for the development of a label free assay for bacteria detection. Specifically, our method utilizes a Love wave biosensor based on a Surface Acoustic Wave (SAW) device combined with the isothermal Rolling Circle Amplification (RCA) method; various protocols were tested regarding the DNA amplification and detection, including off-chip amplification at two different temperatures (30 °C and room temperature) followed by acoustic detection and on-chip amplification and detection at room temperature, with the current detection limit being as little as 100 Bacteria Cell Equivalents (BCE)/sample. Our acoustic results showed that the acoustic ratio, i.e., the amplitude over phase change observed during DNA binding, provided the only sensitive means for product detection while the measurement of amplitude or phase alone could not discriminate positive from negative samples. The method's fast analysis time together with other inherent advantages i.e., portability, potential for multi-analysis, lower sample volumes and reduced power consumption, hold great promise for employing the developed assay in a Lab on Chip (LoC) platform for the integrated analysis of Salmonella in food samples.
Rapid inactivation of airborne porcine reproductive and respiratory syndrome virus using an atmospheric pressure air plasma (2020)

Abstract The transmission of airborne diseases in animals poses great risks to animal safety with potential significant economic losses. In this study, we report on the use of a dielectric barrier discharge (DBD) for in‐flight inactivation of an airborne aerosolized porcine reproductive and respiratory syndrome virus. The infectivity of the sampled virus downstream compared to upstream of the DBD reactor as determined by the TCID 50 method showed a ∼3.5 log 10 reduction in the virus titer. Independent testing of the viral genome by the reverse‐transcription quantitative real‐time polymerase chain reaction method confirmed the inactivation with minimal filtering effects. Both short‐lived species such as and and peroxynitrous acid (ONOOH) chemistry at low pH in the virus‐laden droplets are suggested to be responsible for the observed inactivation.
A vehicle-borne urban 3-D acquisition system using single-row laser range scanners (2003)

In this research, a novel vehicle-borne system of measuring three-dimensional (3-D) urban data using single-row laser range scanners is proposed. Two single-row laser range scanners are mounted on the roof of a vehicle, doing horizontal and vertical profiling respectively. As the vehicle moves ahead, a horizontal and a vertical range profile of the surroundings are captured at each odometer trigger. The freedom of vehicle motion is reduced from six to three by assuming that the ground surface is flat and smooth so resulting in the vehicle moving on almost the same horizontal plane. Horizontal range profiles, which have an overwhelming overlay between successive ones, are registered to trace vehicle location and attitude. Vertical range profiles are aligned to the coordinate system of the horizontal one according to the physical geometry between the pair of laser range scanners, and subsequently to a global coordinate system to make up 3-D data. An experiment is conducted where 3-D data of a real urban scene is obtained by registering and integrating 2412 horizontal and vertical range profiles. Two ground truths are used in examination. They are the outputs of a GPS/INS/Odometer based positioning system and a 1:500 digital map of the testing site. Accuracy and efficiency of the method in measuring 3-D urban scene is demonstrated.
Various Carbon Nanomaterials (CNMs) synthesized on powdered activated carbon by CVD reactor (2011)

Synthesis and characterization of composite carbon nanomaterials (CNMs) are reported in this paper. Carbon nanomaterials are produced on oil palm shell powdered activated carbons (PACs), which were impregnated with iron (Fe) catalysts, with the help of sonication bath. Chemical Vapor Deposition (CVD) of C6H6 and C2H2 were used in the presence of hydrogen at various temperatures (ºC). The flow rates of carbon source and hydrogen were varied to study the effect on the types of CNMs. The CNMs were formed directly on the surface of the impregnated PAC, resulting in cleaner production compared to floating catalyst method. Variable weight percentage (1, 3, 5, and 7%) of the catalyst salt (Fe+3) were used for the impregnation. However, the best catalysis was observed on the substrate with 5% Fe+3. The product displayed a relatively high surface area, essentially constituted by the external surface. New functional groups were also appeared compared to those in the PAC. Field Emission Scanning Microscopy (FESEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) and Energy Dispersive X-ray (EDX) were used for the characterization of the new carbon nanoproduct, which was produced through a clean novel process.
