Solid-state electrochromic device consisting of amorphous WO3 and Cr2O3 (1979)

The electrochromic (EC) characteristics were investigated on a solid-state EC device In2O3/a-WO3//Cr2O3/Au which was prepared by vacuum deposition. Besides the color change caused by passage of current in the WO3 layer, the color of the Cr2O3 layer was also changed as a result of electrochemical reaction at the interface. In the open-circuit condition after the coloration, rapid spontaneous discoloration was found due to bimolecular recombination of the colored species in both layers at the interface. The existence of adsorbed water molecules in the respective layers is essential for the solid-state ECD. The ECD in this study was scarcely affected by the ambient condition and was able to operate in the high vacuum (e.g., 10—6 Torr) since the Cr2O3 layer adsorbed water tightly. Positive polarization of the Cr2O3 layer in an electrolyte solution (Na2SO4 aqueous solution) caused change in the color as a result of electrochemical reaction, whereas the coloration of a-WO3 was taken place by negative polarization of the a-WO3. We have confirmed that this ECD could be operated without any conspicuous deterioration after the reversible switching cycles more than 5×106 times.

No evidence of association of the <i>MYO9B</i> polymorphisms with celiac disease in the Spanish population (2006)

Inconsistent results concerning the association of polymorphisms in the MYO9B gene with celiac disease (CD) have been recently published. This gene encodes a myosin with a guanosine-triphosphatase (GTPase)-activating protein domain for the Rho-family of small G proteins, which are involved in cytoskeleton remodeling and therefore potentially involved in intestinal permeability. Functional and positional reasons led us to investigate the role of MYO9B polymorphisms in the Spanish CD population. A case-control study, including 415 CD patients and 433 ethnically matched healthy controls, and a familial study, including parents of 145 of those CD patients, was performed. Six MYO9B variants previously associated with CD were analyzed: rs2305767, rs2279003, rs962917, rs1457092, rs2305765 and rs2305764. No MYO9B variants or MYO9B haplotypes were found associated with CD, either before or after stratification of the patients for the human leucocyte antigen (HLA)-DQ2-positive risk factor. The family study revealed no distorted transmission of the aforementioned MYO9B polymorphisms or haplotypes. Our results support a negligible influence of this gene on CD predisposition.

Wettability and thermal stability of fluorocarbon films deposited by deep reactive ion etching (2005)

Fluorocarbon films have low surface energy and can be used as antistiction coating for microelectromechanical systems. By using the passivation process in a deep reactive ion etcher, the fluorocarbon films can be deposited and integrated with other processes in the clean room. The properties such as wettability, surface energies, and thermal stability, have been investigated in detail. It has been found that the fluorocarbon films deposited have a static water contact angle of 109° and a surface energy around 14.5mJ∕m2, whereas as-received and as-deposited single silicon, poly silicon, and silicon nitride have a much lower water contact angle and a higher surface energy. The fluorocarbon films keep their good hydrophobicity up to 300°C, and the degradation temperature depends on the thickness of the fluorocarbon films. Decomposition happens at lower temperatures (100–300°C) even though the decomposition rate is quite slow without affecting the contact angle. The decomposition mechanism at low temperatures (less than 300°C) might be different from that at high temperatures. It has been shown that the fluorocarbon film deposited by a deep reactive ion etcher tool provides very high hydrophobicity, low surface energy, good thermal stability, and antiadhesion behavior for use in nanoimprinting lithography.
Measurement of the mass flow rate of airborne powdered material in a duct (1968)

A description is given of two instruments developed to provide, in combination, absolute on-stream measurement of the mass flow of powdered materials. The range of application is typically to duct diameters from 0·1 to 0·6 m, with powders of top size not exceeding 500 μm and mass flows from about 1 to 20 kg s−1. The instruments described are an ultrasonic velocity meter and a density meter relying on β-ray attenuation. The velocity meter measures the carrier air velocity, but it has been shown theoretically that for a wide range of conditions the mean slip between air and particles is small and calculable, so that measurement of the air velocity yields the solid velocity. The β-ray absorption gauge achieves a mean value of the density across a diameter by incorporation of a collimation system that obviates errors that would otherwise arise owing to non-uniform flow distribution across the pipe. The combined instrument is capable of measuring mass flow to 5% or better and has the advantage of not requiring the insertion of impedances into the flow.
Technical Solutions to Overcrowded Park and Ride Facilities (2007)

This report presents the results on potential techniques to more efficiently utilize existing park and ride technologies and plan for future changes to the park and ride facilities. It presents: (1) A summary of parking monitoring and parking guidance systems and recommendations that includes a cost analysis using three technologies: magnetometer, video image processing and inductive loop detectors for a typical parking installation; (2) A prototype parking information and reservation system through the web and cell phone that includes a parking reservation algorithm and solution methodology, a web-based parking reservation system and a cell-phone based parking reservation and information system. The establishment of a web and cell phone based parking information and reservation system is recommended as the main technology to efficiently allocate the parking spaces from overcrowded to underutilized park and ride facilities; and (3) A prototype park and ride intermodal transportation planning model and a case study implementation, with the model recommended to be expanded as a real-time traffic and park and ride forecasting system to enhance the operations and planning of park and ride facilities.
Calculation of spin transfer torque in partially polarized spin valves including multiple reflections (2010)

An analytic expression that includes the effect of multiple reflections within the interface of a spin-valve composed of materials with partial spin polarization was obtained. Inclusion of this term in a micromagnetic calculation demonstrates the effect of the spin polarization of the magnetic material on the current induced behavior of the structure. We show that neglecting to include interfacial scattering events results in an underestimation of the switching current compared to the method detailed in this letter. Multiple reflections also produce a strong dependence of the switching current on the magnetocrystalline anisotropy of the fixed layer.

The Nerve Fiber Layer in the Diagnosis of Glaucoma (1977)

Serial fundus photographs of 14 eyes that eventually developed glaucomatous visual field defects and 110 slides from 76 eyes of race- and age-matched controls were reviewed in randomized masked fashion. Each eye that lost visual field demonstrated consistent abnormalities of the nerve fiber layer, beginning as early as 5 years (mean, 1 1/2 years) before it developed glaucomatous visual field defects on routine Goldmann perimetry. Preliminary estimates, based on regression analysis of this small series, suggest that half of these eyes (median) might demonstrate such reproducible abnormalities between four and six years before onset of their visual field defects. Only 9% of the matched controls showed similar nerve fiber layer changes, and in the one instance where analysis was possible, these were inconsistent and nonreproducible. Nerve fiber layer assessment by means of fundus photographs may be the earliest, surest means of distinguishing ocular hypertension from true glaucoma.
Discovery and Identification of Small Molecules as Methuosis Inducers with <i>in Vivo</i> Antitumor Activities (2018)

Methuosis is a novel nonapoptotic mode of cell death characterized by vacuole accumulation in the cytoplasm. In this article, we describe a series of azaindole-based compounds that cause vacuolization in MDA-MB-231 cells. The most potent vacuole inducer, compound 13 (compound 13), displayed differential cytotoxicities against a broad panel of cancer cell lines, such as MDA-MB-231, A375, HCT116, and MCF-7, but it did not inhibit the growth of the nontumorigenic epithelial cell line MCF-10A. A mechanism study confirmed that the cell death was caused by inducing methuosis. Furthermore, compound 13 exhibited substantial pharmacological efficacy in the suppression of tumor growth in a xenograft mouse model of MDA-MB-231 cells without apparent side effects, which makes this compound the first example of a methuosis inducer with potent in vivo efficacy. These results demonstrate that methuosis inducers might serve as novel therapeutics for the treatment of cancer.
Optical pulse compression in dispersion decreasing photonic crystal fiber (2007)

Improvements to tapered photonic crystal fiber (PCF) fabrication have allowed us to make up to 50 m long PCF tapers with loss as low as 30 dB/km. We discuss the design constraints for tapered PCFs used for adiabatic soliton compression and demonstrate over 15 times compression of pulses from over 830 fs to 55 fs duration at a wavelength of 1.06 lm, an order of magnitude improvement over previous results.
Fluid transport across cultures of human tracheal glands is altered in cystic fibrosis (1997)

1. There is evidence that defective submucosal gland secretion contributes to the airway pathology of cystic fibrosis (CF). Using a capacitance probe technique, we have compared fluid transport across submucosal gland cultures from individuals with and without CF. 2. Under baseline conditions, approximately 60% of non-CF cultures secreted fluid; the rest absorbed. In secreting tissues, amiloride increased secretion, whereas in absorbing tissues it reduced or reversed absorption. 5-Nitro-2(3-phenylpropylamino)-benzoate (NPPB) a blocker of the CF transmembrane conductance regulator (CFTR), converted secretion to absorption. Thus, the direction and magnitude of baseline fluid movement depended on a balance between active absorption of Na+ and cAMP-dependent secretion of Cl-. 3. 8-(4-Chlorophenylthio)-adenosine 3',5'-cyclic monophosphate (CPT-cAMP), methacholine and luminal uridine 5'-triphosphate (UTP) all induced or increased fluid secretion across non-CF cultures. Results with NPPB and with 4,4'-diisothiocyanatostilbene-2,2'-disulphonate (DIDS), a blocker of Ca(2+)-activated Cl- channels, suggested that fluid secretion induced by CPT-cAMP was mediated primarily by CFTR; UTP acted entirely via Ca(2+)-activated Cl- channels, and methacholine activated both pathways. 4. All CF cultures showed baseline fluid absorption, which was abolished by amiloride. 5. CF cultures showed a normal secretory response to UTP, a reduced response to methacholine, and no response to CPT-cAMP. 6. Thus, the absorptive processes of airway glands are retained in CF, but the cAMP-dependent secretory process is lost. This would markedly reduce the water content of gland secretions. The resulting change in viscosity would contribute to the accumulation of airway mucus which is characteristic of this disease.

Quakers Hill SPV Pty Limited (the Applicant) owned land at 9 Nirimba Drive, Quakers Hill. The Applicant had the right to a 7m wide Right of Carriageway (ROC) over a strip of land owned by Sertari Pty Limited, the intervener, at 7 Nirimba Drive. The ROC was the only means of vehicular access to the Applicant's land, and allowed for direct pedestrian access from the Applicant's land to the Quakers Hill Railway Station.
Stride length in distance running: velocity, body dimensions, and added mass effects. (1989)

The preferred stride frequency (SF) and stride length (SL) of male recreational distance runners were measured on a level treadmill under a variety of conditions over the typical distance running speed range of 3.15-4.12 m.s-1. At a given speed, the correlation coefficients between the subjects' anthropometric variables (APV) (such as stature, leg length, and limb segment mass) and their preferred stride variables were consistently low (less than or equal to 0.36) and not significantly different from zero. As speed increased through the experimental range, SF remained nearly constant (only a 4% increase) while SL increased by 28%. The use of dimensionless velocity was shown to be no more effective than conventional methods in the prediction of a SL vs velocity relationship, but the dimensionless form of the relationship was remarkably similar to those observed for other animal species and other forms of gait. The addition of masses up to 1.1 kg at each ankle produced no significant change in SF or SL. The results indicate that factors other than APV are the primary determinants of preferred SF and SL. Since it has been shown previously that the preferred SL is usually the most economical, APV cannot be used to accurately predict or prescribe SF or SL on an individual basis.

Anti‐Markovnikov Hydrofunctionalization of Alkenes: Use of a Benzyl Group as a Traceless Redox‐Active Hydrogen Donor (2017)

A protocol for the anti-Markovnikov hydrofunctionalization of alkenes has been developed by the use of a benzyl group as a traceless redox-active hydrogen donor. Under copper catalysis and in the presence of CF<sub>3</sub> - or N<sub>3</sub> -containing hypervalent iodine reagents, a series of homoallylic alcohol derivatives were hydrofunctionalized regioselectivity. A similar principle was also applied to the hydrofunctionalization of alkenols.
Contribution of Polycomb group proteins to olfactory basal stem cell self-renewal in a novel c-KIT+ culture model and <i>in vivo</i> (2016)

Olfactory epithelium (OE) has a lifelong capacity for neurogenesis due to the presence of basal stem cells. Despite the ability to generate short-term cultures, the successful in vitro expansion of purified stem cells from adult OE has not been reported. We sought to establish expansion-competent OE stem cell cultures to facilitate further study of the mechanisms and cell populations important in OE renewal. Successful cultures were prepared using adult mouse basal cells selected for expression of c-KIT. We show that c-KIT signaling regulates self-renewal capacity and prevents neurodifferentiation in culture. Inhibition of TGFβ family signaling, a known negative regulator of embryonic basal cells, is also necessary for maintenance of the proliferative, undifferentiated state in vitro Characterizing successful cultures, we identified expression of BMI1 and other Polycomb proteins not previously identified in olfactory basal cells but known to be essential for self-renewal in other stem cell populations. Inducible fate mapping demonstrates that BMI1 is expressed in vivo by multipotent OE progenitors, validating our culture model. These findings provide mechanistic insights into the renewal and potency of olfactory stem cells.
Study on conductor configuration of 500-kV Chang-Fang compact line (2003)

The conductor configuration is a basic and key problem, it ought to be determined first in the compact line design and is mutually related with many other factors. In the paper, the relevant philosophy is concisely introduced; several conductor configuration schemes of the 500 kV compact lines are compared with each other and with a typical 500 kV conventional line. The electrical and environmental effect parameters of different configuration schemes are assessed as well.
Espessura central e periférica da córnea: influência na medida da pressão intra-ocular pelo Tonopen (2006)

There was a positive correlation between the measurements performed with Tonopen XL and Goldmann's tonometer at the central region of the cornea and the mean IOP was higher with Tonopen XL. The mean IOP obtained by TP was higher than that obtained by TC. These data showed that Tonopen XL, besides providing higher IOP readings than those with Goldmann's tonometer, is influenced by the corneal thickness presenting higher IOP readings in the periphery than in the central region of the cornea.
Corncob Harvest with Counter-Rotating Rollers (1983)

ABSTRACT SAMPLES of combine discharge that were collected during corn harvest were analyzed to determine the constitution of the sieve and walker discharges. Corncobs were classified on the basis of their cross-sectional shape and length. A corncob separator using counter rotating rollers for separation of cobs from husks was designed, constructed and tested. Field tests with the corncob separator indicated a high percentage of clean cobs and a high percentage of cob recovery.
Purely Electronic and Vibronic Fluorescence Excitation of Single Terrylene Molecules in a Naphthalene Crystal (2007)

Fluorescence excitation spectra of spatially resolved single terrylene molecules in a naphthalene crystal were studied at 5 K as a function of exciting laser light intensity. The fully saturated fluorescence detection rate for purely electronic transition (0,0) was found to be about twice smaller than that for the two main vibronic components located 239 and 251 cm -1 above. This relation is fulfilled when the triplet population rate k23 is much weaker than the depopulation rate k 31 . We propose that the weak fluorescence excitation lines observed at the frequencies of 38, 67, 97, and 145 cm -1 correspond to nontotally symmetric low-frequency vibration modes of terrylene.
A Germ Line Mutation in the Death Domain of DAPK-1 Inactivates ERK-induced Apoptosis (2007)

p53 is activated genetically by a set of kinases that are components of the calcium calmodulin kinase superfamily, including CHK2, AMP kinase, and DAPK-1. In dissecting the mechanism of DAPK-1 control, a novel mutation (N1347S) was identified in the death domain of DAPK-1. The N1347S mutation prevented the death domain module binding stably to ERK in vitro and in vivo. Gel filtration demonstrated that the N1347S mutation disrupted the higher order oligomeric nature of the purified recombinant death domain miniprotein. Accordingly, the N1347S death domain module is defective in vivo in the formation of high molecular weight oligomeric intermediates after cross-linking with ethylene glycol bis(succinimidylsuccinate). Full-length DAPK-1 protein harboring a N1347S mutation in the death domain was also defective in binding to ERK in cells and was defective in formation of an ethylene glycol bis(succinimidylsuccinate)-cross-linked intermediate in vivo. Full-length DAPK-1 encoding the N1347S mutation was attenuated in tumor necrosis factor receptor-induced apoptosis. However, the N1347S mutation strikingly prevented ERK:DAPK-1-dependent apoptosis as defined by poly(ADP-ribose) polymerase cleavage, Annexin V staining, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling imaging. Significant penetrance of the N1347S allele was identified in normal genomic DNA indicating the mutation is germ line, not tumor derived. The frequency observed in genomic DNA was from 37 to 45% for homozygous wild-type, 41 to 47% for heterozygotes, and 12 to 15% for homozygous mutant. These data highlight a naturally occurring DAPK-1 mutation that alters the oligomeric structure of the death domain, de-stabilizes DAPK-1 binding to ERK, and prevents ERK:DAPK-1-dependent apoptosis.
