Densimeters for very accurate density measurements of fluids over large ranges of temperature, pressure, and density (2004)

This paper comprehensively describes those types of densimeters that allow very accurate density measurements of fluid substances over large ranges of temperature and for high pressures and that also cover the entire density range from low gas densities up to high densities of compressed liquids. Densimeters meeting these requirements are based on special applications of hydrostatic balances in combination with magnetic suspension couplings. These densimeters can be subdivided into two-sinker densimeters, and single-sinker densimeters which allow pρT measurements with total uncertainties in density of about 0.01% to 0.02% (level of confidence 95%) depending on their individual design. Besides a discussion of the design of such densimeters, it is also shown which substances in which ranges of the fluid state have been investigated with these instruments. Using nitrogen as an example, the experimental results obtained with these densimeters are discussed and compared with the pρT data obtained with other types of densimeters. A description of the features of other types of densimeters is outside the scope of this paper, but they are briefly summarized at the beginning of this paper.
Design and operation of distributed feedback transistor lasers (2010)

The design and fabrication methods utilizing soft photocurable nanoimprint lithography to realize single longitudinal mode distributed feedback transistor lasers are investigated. Coupled-mode theory and the effective index method are used to determine accurately the periodic dimensions necessary to integrate a surface grating in the top emitter AlGaAs confining layers of an InGaP/GaAs/InGaAs heterojunction bipolar transistor laser. Electrical and optical device data confirm the design methods. The distributed feedback device produces continuous wave laser operation with a peak wavelength λ=959.75 nm and threshold current IB=13 mA operating at −70 °C. For devices with cleaved ends a side mode suppression ratio &gt;25 dB has been achieved.
Endogenous digoxin-like immunoreactive factors eliminated from serum samples by hydrophobic silica-gel extraction and enzyme immunoassay. (1987)

Elimination of endogenous digoxin-like immunoreactive factors (DLIF) that interfere with accurate measurement of digoxin requires use of a highly specific anti-digoxin antibody, or that DLIF be separated from digoxin before immunoassay. Several commercial digoxin-assay kits include a step for separating serum proteins and other substances from digoxin before immunoassay. We tested six different immunoassay methods (some having pretreatment steps) for their ability to detect DLIF in serum from patients in renal failure, pregnant women, and neonates, all of whom were not taking digoxin. Extracting digoxin on a column of derivatized silicagel eliminated detectable DLIF from serum as measured by enzyme immunoassay (EMIT; Syva Co.), but recovery of added digoxin was quantitative. In contrast, protein precipitation with 5-sulfosalicylic acid left significant amounts of DLIF in samples, most probably because the procedure (TDx assay; Abbott Labs.) disrupted protein-DLIF binding. A glass-bead radioimmunoassay (Immophase; Corning Medical) had the most digoxin-specific antisera. By preparative silica-gel-chromatography of serum we could eliminate or significantly minimize inaccurate digoxin measurements attributable to endogenous DLIF.
Mississippi County Community College Solar Photovoltaic Total Energy Project (1979)

Mississippi County Community College at Blytheville, Arkansas, will derive its total electrical and thermal energy demand from an actively cooled photovoltaic energy system being developed under the management of TEAM, Inc. of Springfield, Virginia. The facility has a design peak electrical requirement for 240 kw to be supplied by a 26-sun concentrating collector field that fully tracks E-W. A 2.4 megawatt-hour electrical energy storage system under consideration is an iron redox system using FeCl2 electrolyte and pressure-molded carbon/PVC electrodes. The power conditioning system will include a 300-kw solid-state inverter to furnish 480-v, three-phase, 60-Hz ac to the College, and appropriate switching to acquire utility company power in emergencies. Process control includes the capability to gather vital signs on the collectors, thermal loop, electrical storage and building demands, and to provide closed-loop tracking and all control signals for energy efficient operation of the total system.
3D gaze point localization and visualization using LiDAR-based 3D reconstructions (2016)

We present a novel pipeline for localizing a free roaming eye tracker within a LiDAR-based 3D reconstructed scene with high levels of accuracy. By utilizing a combination of reconstruction algorithms that leverage the strengths of global versus local capture methods and user-assisted refinement, we reduce drift errors associated with Dense-SLAM techniques. Our framework supports region-of-interest (ROI) annotation and gaze statistics generation and the ability to visualize gaze in 3D from an immersive first person or third person perspective. This approach gives unique insights into viewers' problem solving and search task strategies and has high applicability in complex static environments such as crime scenes.

Neurogenic effect of vascular endothelial growth factor during germ layer formation of human embryonic stem cells (2006)

Vascular endothelial growth factor (VEGF), a potent mitogen for vascular endothelial cells, has been suggested as a modulator that is involved in neurogenesis as well as angiogenesis. Here, we directly examined the effect of VEGF on neuroectodermal differentiation using human embryonic stem cells (hESCs). VEGF treatment upregulated the expression of neuroectodermal genes (Sox1 and Nestin) during germ layer formation in embryoid bodies (EBs) and efficiently increased the number of neural rosettes expressing both Pax6 and Nestin. The neural progenitors generated from VEGF-treated EBs further differentiated into cells that showed a similar pattern of gene expression observed in the development of dopaminergic neurons upon terminal differentiation. These results support the neurogenic effect of VEGF on hESC differentiation.
Fluorescent water-soluble perylenediimide-cored cationic dendrimers: synthesis, optical properties, and cell uptake (2013)

Different generations of perylenediimide-cored dendrimers with peripheral amine groups were synthesized. All these water-soluble dendrimers could rapidly internalize into live cells with high efficacy of gene transfection and low cytotoxicity. Increasing dendrimer generation increased their ability for gene transfection.

Molecular mechanisms of glutamate receptor clustering at excitatory synapses (1998)

The targeting of AMPA- and NMDA-type glutamate receptors to synapses in the central nervous system is essential for efficient excitatory synaptic transmission. Recent studies have indicated that protein-protein interactions of these receptors with synaptic proteins that contain PDZ domains are crucial for receptor targeting. NMDA receptors have been found to bind to the PSD-95 family of proteins, whereas AMPA receptors interact with the PDZ-domain-containing protein GRIP (glutamate receptor interacting protein). PSD-95 and GRIP contain multiple PDZ domains as well as other protein-protein interaction motifs that help to form large macromolecular complexes that may be important for the formation and plasticity of synapses.
Impaired ventilatory responses to hypoxia and hypercapnia in mutant mice deficient in endothelin-1 (1996)

We studied respiratory functions in mutant mice deficient in endothelin-1 (ET-1) generated by gene targeting. In conscious adult mice heterozygous for ET-1 gene mutation (ET+/- heterozygous mice), arterial PO2 was significantly lower, PCO2 tended to be higher, and pH tended to be lower than in wild-type littermates. When these conscious mice breathed room air, respiratory minute volume and rate, determined by body plethysmography, were not significantly different between the two groups. However, when ET+/- heterozygous mice were subjected to systemic hypoxia (1:1 air-N2) or hypercapnia (5% CO2-95% O2), increases in respiratory minute volume were significantly attenuated. In conscious newborn ET-/- homozygous mice delivered by cesarean section and tracheotomized, ventilatory responses to systemic hypoxia and hypercapnia, regularly observed in newborn wild-type mice, were almost totally absent. In urethan-anesthetized adult ET+/- heterozygous mice, increases in phrenic nerve discharges in response to hypoxia and hypercapnia were significantly attenuated. Our results demonstrate that ventilatory responses to hypoxia and hypercapnia are impaired in ET-1-deficient mice and suggest that endogenous ET-1 participates in the physiological control of ventilation.
Immunohistochemical Study of Small Cell Lung Carcinoma; With Special Reference to the Neuroendocrine Markers Aromatic L-Amino Acid Decarboxylase and Gastrin-Releasing Peptide (1986)

Forty-seven surgically resected small cell lung carcinomas (SCLC) were immunohistochemically studied by using antibodies to various neuroendocrine and epithelial markers. SCLC was shown to be subdivided into two categories, with and without the immunoreactive neuroendocrine markers aromatic L-amino acid decarboxylase, gastrin-releasing peptide, serotonin, chromogranin A and neurofilament protein. Neuron-specific enolase (NSE) and creatine kinase BB isoenzyme (CK-BB), which are also considered to be neuroendocrine markers, had a tendency to be widely distributed in the SCLC with a neuroendocrine marker, but the immunoreactivity for both NSE and CK-BB varied in the SCLC without neuroendocrine markers. Therefore they were not included in the classification. Epithelial markers keratin, involucrin and epithelial membrane antigen were frequently observed in the SCLC with neuroendocrine markers, but less so in the SCLC without neuroendocrine markers. The data are discussed briefly in relation to "classic and variant" forms of SCLC in vitro and to a recently proposed histological classification of SCLC.
Coaxial Triboelectric Nanogenerator and Supercapacitor Fiber-Based Self-Charging Power Fabric (2018)

Although there has been rapid advancement in wearable electronics, challenges still remain in developing wearable and sustainable power sources with simple fabrication and low cost. In this work, we demonstrate a flexible coaxial fiber by fabricating a one-dimensional triboelectric nanogenerator (TENG) outside and a supercapacitor (SC) inside, which can not only harvest mechanical energy but also store energy in the all-in-one fiber. In such a coaxial fiber, carbon fiber bundles are utilized as the electrode material for the TENG as well as the active and electrode material for the SC. Meanwhile, silicone rubber serves as the separator between the SC and TENG, as the triboelectric material for the TENG, and as the encapsulation material for the whole fiber as well. Moreover, both SC and TENG exhibit good performance and stability, which ensures their long-term use in daily life. Because of the flexibility and durability of the carbon fiber and silicone rubber, the proposed coaxial fibers show great flexibility, which could be further knitted as cloth for sustainably powering wearable electronic devices. This work presents a promising platform for wearable electronics as well as smart textiles.

Synthesis, Molecular Structure, and Electrochemistry of a Paramagnetic Diruthenium(III) Complex. Characterization of Ru<sub>2</sub>(hpp)<sub>4</sub>Cl<sub>2</sub>, Where hpp Is the 1,3,4,6,7,8- Hexahydro-2<i>H</i>-pyrimido[1,2-<i>a</i>]pyrimidinate Ion (1996)

The synthesis and characterization of the first paramagnetic diruthenium(III) complex containing two unpaired electrons is described. The investigated compound, represented as Ru2(hpp)4Cl2, where hpp is 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidinate ion, was obtained from the reaction of Ru2(CH3COO)4Cl with excess molten Hhpp under Ar (150 °C, 10 h). It was characterized by X-ray single-crystal diffraction, electrochemistry, ESR, and UV−visible spectroscopy and the data compared to that for other Ru26+ derivatives containing either four unpaired electrons (in the case of a bis-H2O complex) or zero unpaired electrons (in the case of a bis-C⋮CC6H5 derivative).
Can computers visually quantify human thermal comfort? (2016)

The main driving factor in determining control settings of an air conditioning system is indoor thermal condition and its association with occupants' satisfaction. In recent years, the ubiquity of computing devices has led to techniques for learning personalized thermal comfort by using feedback through smartphones or (commonly wearable) sensors to measure physiological variables. In this paper, seeking a non-contact and non-intrusive approach, we are investigating whether computers could visually identify human thermal comfort by using digital videos. This investigation has been conducted in the form of developing a specialized image processing algorithmic framework, which relies on Eulerian image magnification approach. This approach amplifies subtle changes in the human physiological signals that are associated with thermoregulation. The proposed framework has been evaluated through experimental studies on human subjects in a thermal chamber with hot and cold thermal conditions. The quantified results demonstrated that the proposed framework has effectively identified the thermoregulation states of the human subjects.

Optical Coherence Tomography (OCT) in Neuro-ophthalmology: A Clinical Perspective (2008)

Optical coherence tomography (OCT) is a non-invasive method used to evaluate the retina and the optic nerve. Since its inception, OCT has become a valuable adjunct to the clinical examination in neuro-ophthalmology. In this article we review some of the more common uses for OCT, including differentiating optic nerve pathology from retinal pathology, and following optic nerve swelling and/or atrophy over time. Clinical examples are provided to show the utility of OCT in both neuro-ophthalmology and general ophthalmology practice.
Terminally Differentiated Human Neurons Survive and Integrate Following Transplantation into the Traumatically Injured Rat Brain (1999)

The present study evaluated the survival and integration of human postmitotic neurons (hNT) following transplantation into the traumatically injured rodent brain. Anesthetized male Sprague-Dawley rats (n = 47) were subjected to lateral fluid percussion brain injury of moderate severity (2.4-2.6 atm). Sham animals (n = 28) were surgically prepared, but did not receive brain injury. At 24 h following injury or sham surgery, the rats were re-anesthetized and approximately 100,000 hNT cells (freshly cultured or previously frozen) or vehicle were stereotactically injected into the ipsilateral cortex. Animals were examined for neuromotor function at 48 h, 7 days, and 14 days posttransplantation using a standard battery of motor tests. Animals were sacrificed at 2 weeks postinjury and viability of hNT grafts was assessed by Nissl staining and MOC-1 immunohistochemistry, which recognizes human neural cell adhesion molecules (NCAM) expressed on hNT cells. Transplanted hNT grafts remained viable in 83% of brain-injured animals at 2 weeks following transplantation of either fresh or frozen hNT cells. Glial fibrillary acidic protein (GFAP) immunohistochemistry revealed a marked increase in the number of reactive astrocytes following brain injury in both vehicle and hNT implanted animals. These reactive astrocytes appeared not to impede grafted cells from sending projections into host tissue. Despite the survival of transplanted cells in the traumatically injured brain, hNT cells had no significant effect on posttraumatic neurologic motor function during the acute posttraumatic period. Since hNT cells are transfectable, prolonged survival of these transplanted cells in the posttraumatic milieu suggests that grafted hNT cells may be a suitable means for delivery of therapeutic, exogenous proteins into the CNS for treatment of traumatic brain injury.
Expression, Glycosylation, and Secretion of an <i>Aspergillus</i> Glucoamylase by <i>Saccharomyces cerevisiae</i> (1985)

A strain of Saccharomyces cerevisiae capable of simultaneous hydrolysis and fermentation of highly polymerized starch oligosaccharides was constructed. The Aspergillus awamori glucoamylase enzyme, form GAI, was expressed in Saccharomyces cerevisiae by means of the promoter and termination regions from a yeast enolase gene. Yeast transformed with plasmids containing an intron-free recombinant glucoamylase gene efficiently secreted glucoamylase into the medium, permitting growth of the transformants on starch as the sole carbon source. The natural leader sequence of the precursor of glucoamylase (preglucoamylase) was processed correctly by yeast, and the secreted enzyme was glycosylated through both N- and O-linkages at levels comparable to the native Aspergillus enzyme. The data provide evidence for the utility of yeast as an organism for the production, glycosylation, and secretion of heterologous proteins.
Electron Impact Induced Loss of C‐5/C‐8 Substituents of 1,2,3,4‐Tetrahydroisoquinolines, VI<sup>1)</sup>: Synthesis and Mass Spectrometric Fragmentation of Dihydroindole Derivatives (1990)

Abstract The syntheses of the C‐4 substituted dihydroindoles 25, 31 (scheme 7), and 36 (scheme 8) are described. ‐ The CID MIKE spectrum in the 2. field free region (2. FFR) of m/z 146 from 25 is very similar to but not identical with that of m/z 146 from the C‐5 substituted tetrahydroisoquinolines 3, 6, 7 , and 8 (scheme 2), so supporting our hypothesis of a rearrangement in M + of tetrahydroisoquinolines 1) prior to fragmentation, but not proving it. As the CID MIKE spectra of the tetrahydroisoquinolines 3, 6, 7 , and 8 are not identical among each other we assume that a 1.3‐H‐shift takes places in their M + in competition to the rearrangement mentioned above.
Reactivity of nonaqueous organic electrolytes towards lithium (1990)

The successful operation of an ambient temperature secondary lithium cell is primarily dependent on the stability of the electrolyte towards lithium. The lithium electrode on open circuit must be inert towards the electrolyte to achieve a long shelf life. The reactivity of tetrahydrofuran and 2-methyltetrahydrofuran based electrolytes with additives such as 2-methylfuran, ethylene carbonate, propylene carbonate, and 3-methylsulfolane was investigated by microcalorimetry and ac impedance spectroscopy techniques. Also the stability of electrolytes by open circuit stand tests was studied. Addition of ethylene carbonate and 2-methylfuran additives was found to improve the stability of tetrahydrofuran and 2-methyltetrahydrofuran based electrolytes. Long term microcalorimetry and ac impedance data clearly confirmed the higher stability of ethylene carbonate/2-methyltetrahydrofuran electrolyte compared to the 2-methyltetrahydrofuran and propylene carbonate/2-methyltetrahydrofuran electrolytes.
