Analysis of optomechanical coupling in two-dimensional square lattice phoxonic crystal slab cavities (2013)

We theoretically investigate phonon-photon interaction in cavities created in a phoxonic crystal slab constituted by a two-dimensional (2D) square array of holes in a silicon membrane. The structure without defects provides 2D band gaps for both electromagnetic and elastic waves. We consider two types of cavities, namely, an L3 cavity (a row of three holes is removed) and a cross-shape cavity, which both possess highly confined phononic and photonic localized modes suitable for enhancing their interaction. In our theoretical study, we take into account two mechanisms that contribute to optomechanical interaction, namely, the photoelastic and the interface motion effects. We show that, depending on the considered pair of photonic and phononic modes, the two mechanisms can have similar or very different magnitudes, and their contributions can be either in or out of phase. We find out that only acoustic modes with a specific symmetry are allowed to couple with photonic cavity modes. The coupling strength is quantified by two different methods. In the first method, we compute a direct estimation of coupling rates by overlap integrals, while in the second one, we analyze the temporal modulation of the resonant photonic frequency by the phonon-induced acoustic vibrational motion during one acoustic period. Interestingly, we obtain high optomechanical interaction, with the coupling rate reaching more than 2.4 MHz for some specific phonon-photon pairs.
[Experimental studies on the mode of action of cyclosporine and FK506 assessed by proliferation response of human cloned T lymphocytes]. (1991)

We applied cloned human T lymphocytes established in our laboratory to evaluate the mode of action of Cyclosporine (CsA) and FK506. Phenotypic and functional analysis led us to conclude that HTL403 was a helper T cell clone and HTL805 a cytotoxic one. Susceptibility of HTL-403 to the immunosuppressants demonstrated that alloantigen-driven proliferative response can recover to the rIL2-driven level by the addition of rIL2 at higher concentration of the agents. Although full recovery was not observed in FK506, this finding indicated that FK506 as well as CsA inhibit IL2 secretion from HTL403. FK506 showed remarkable suppressive effect on the proliferative response of HTL-805 even at a considerably low concentration, while CsA suppressed such a response dose-dependently. We concluded that FK506 can be used to reverse ongoing acute rejection as well as to prevent acute rejection.
Étude structurale de quelques cyclanones par mesures de moments dipolaires et calculs théoriques CNDO/2 (1980)

Les moments dipolaires d'une série de cyclanones (cyclohexanone, cyclononanone, cyclodécanone, cycloundécanone, cyclododécanone et cyclotridécanone) ont été mesurés dans le tétrachlorure de carbone à 25°C ; le moment de la cyclohexanone et de la cyclodécanone ont été également mesurés à 40 et 60°C.
Selective, Specific, and Versatile Personal Biosensors to Organophosphate Chemical Toxins Composed of Polyurethane Immobilized Enzymes (2002)

Organophosphorus (OP) nerve agents are a serious threat to military and civilian personnel, so rapid detection of OP compounds in all of these forms is of paramount importance to prevent casualties. Recently, we combined porous polyurethane foam formed in situ from water-miscible hydrophilic urethane prepolymers and enzymes such as ChEs. One of the advantages of this technique imparted to the immobilized enzymes is resistance to denaturing events. Most important, the enzyme will not leach from the polyurethane support so the ChE-badge can now be used to sample for OPs in diverse environments such as soil and large bodies of water, as well as conventional sources such as air. In addition, immobilized enzyme badges are being designed with a unique attribute not present in the current nonimmobilized detectors: a rapid field system to identifying which OP is present. For instance, organophosphorus hydrolase (OPH) hydrolyzes sarin more readily than soman, while laccase hydrolyzes the VX agent preferentially over the G agent OPs. Currently, we are evaluating polyurethane immobilized laccase for long-term stability and kinetic properties of VX hydrolysis. Thus, the immobilized sensor can provide new features and testing of more diverse environments than the M256A1 and M272 kits combined. Also, the ability to identify the OP toxin in real-time using the immobilized differential detector would aid in treatment and securing the contaminated area, in the identification of the use of OPs, and permitting first responders to identify the OP present in a civilian terrorist act.

Avian Paramyxovirus Type-3 as a Vaccine Vector: Identification of a Genome Location for High Level Expression of a Foreign Gene (2017)

Avian paramyxovirus serotype 3 (APMV-3) causes infection in a wide variety of avian species, but it does not cause apparent diseases in chickens. On the contrary, APMV-1, also known as Newcastle disease virus (NDV), can cause severe disease in chickens. Currently, natural low virulence strains of NDV are used as live-attenuated vaccines throughout the world. NDV is also being evaluated as a vaccine vector against poultry pathogens. However, due to routine vaccination programs, chickens often possess pre-existing antibodies against NDV, which may cause the chickens to be less sensitive to recombinant NDV vaccines expressing antigens of other avian pathogens. Therefore, it may be possible for an APMV-3 vector vaccine to circumvent this issue. In this study, we determined the optimal insertion site in the genome of APMV-3 for high level expression of a foreign gene. We generated recombinant APMV-3 viruses expressing the green fluorescent protein (GFP) by inserting the GFP gene at five different intergenic regions in the genome. The levels of GFP transcription and translation were evaluated. Interestingly, the levels of GFP transcription and translation did not follow the 3'-to-5' attenuation mechanism of non-segmented, negative-sense RNA viruses. The insertion of GFP gene into the P-M gene junction resulted in higher level of expression of GFP than when the gene was inserted into the upstream N-P gene junction. Unlike NDV, insertion of GFP did not attenuate the growth efficiency of AMPV-3. Thus, APMV-3 could be a more useful vaccine vector for avian pathogens than NDV.
Efficient nanotube-driven amplifier (2006)

Summary form only given. A compact nanotube-driven microwave amplifier (NDXA) is currently under development at Microwave Technologies Inc. The NDXA is a compact two-cavity system that uses a rugged carbon-nanotube cold-cathode to produce microwave radiation with very high efficiency, making it ideal for airborne applications. We will present preliminary experimental results of our amplifier prototype. The NDXA should be capable of replacing conventional traveling-wave tubes in future radar and communication systems by offering substantial improvements over its counterparts, in size, weight, and, especially efficiency
Estimation of Arterial Mechanical Properties from Aortic and Tonometric Arterial Pressure Waveforms (1997)

Although arterial mechanical properties have been evaluated using arterial input impedance, the relative difficulty in accurate flow measurement made the value of impedance somewhat limited. To develop an alternative method to evaluate arterial mechanical properties, we analyzed the aortic pressure (AoP)-radial arterial pressure (RAP) relationship because of relative ease in obtaining peripheral pressure waveform by tonometry. In 8 patients we simultaneously recorded aortic root and radial arterial pressure waveforms. We calculated the transfer function from AoP to RAP. We then fitted the transfer function to a model of a lossless uniform elastic tube terminated with a modified Windkessel model. The fact that the model transfer function predicted AoP from RAP waveform with considerable accuracy indicated that the model represented the arterial mechanical properties well. We conclude that we can estimate the arterial mechanical properties by the pressure-pressure transfer function analysis.
Delta expression in post‐mitotic neurons identifies distinct subsets of adult‐specific lineages in Drosophila (2006)

The Drosophila ventral nerve cord is comprised of numerous neuronal lineages, each derived from a stereotypically positioned neuroblast (NB). At the embryonic stage the unique identities of each NB, and several of their neuronal progeny, are well characterized by spatial and temporal expression patterns of molecular markers. These patterns of expression are not preserved at the larval stage and thus the identity of adult-specific lineages remains obscure. Recent clonal analysis using MARCM has identified 24 adult-specific lineages arising from thoracic NBs at the larval stage. In this study, we have explored a role for the Delta protein in development of the post-embryonic Drosophila ventral nerve cord. We find that Delta expression identifies 7 of the 24 adult-specific lineages of the thoracic ganglia by being highly enriched in clusters of newly born post-mitotic neurons and their neurite bundles. The Delta lineages constitute the majority of bundles projecting to the ventral neuropil, consistent with a role in processing leg sensory information. Targeted knockdown of Delta in neurons using RNAi results in significantly decreased leg chemosensory response and a relatively unaffected leg mechanosensory response. Delta RNAi knockdown in Delta lineages also gives a more diffuse bundle terminal morphology while the overall path-finding of neurite bundles is unaffected. We also identify a male-specific Delta lineage in the terminal abdominal ganglia, implicating a role for Delta in development of sexually dimorphic neural networks. Examples of Delta-expressing neurites contacting Notch-expressing glia are also seen, but are not common to all Delta lineages. Altogether, these data reveal a fundamental pattern of Delta expression that is indicative of an underlying developmental program that confers identity to adult lineage neurons.
TUNGSTEN FORGING DEVELOPMENT PROGRAM (1962)

Abstract : The program was revised and extended to adapt the developed forging process to non-structural, thin section tungsten components. A Universal Thin Section configuration and tooling sequence was designed for determination of all basic parameters involved in forging of thin section tungsten shapes. Forging tooling was manufactured. Centrifugally cast and extruded W-2%Mo was selected as the forging billet material for the program. The initial large diameter cast ingot was procured to strict specifications and was successfully extruded to sound forging bar stock. (Author)
Presence of NADP<sup>+</sup>-specific glyceraldehyde-3-phosphate dehydrogenase and CcpA-dependent transcription of its gene in the ruminal bacterium<i>Streptococcus bovis</i> (2006)

To know the role of NADP+-specific glyceraldehyde-3-phosphate dehydrogenase (GAPN) in Streptococcus bovis, the molecular properties and transcriptional control of the gene encoding GAPN (gapN) were examined. The GAPN in S. bovis was deduced to consist of 476 amino acids with a molecular mass of 51.1 kDa. The gapN gene was transcribed in a monocistronic fashion. GAPN synthesis appeared to be regulated at the transcriptional level in response to changes in growth conditions. In a mutant that lacks the ccpA gene encoding catabolite control protein A (CcpA), the gapN-mRNA level was lower than in the parent strain. A binding site of CcpA was found in the upper region of gapN. These results suggest that transcription of gapN is regulated through CcpA. Overexpression of GAPN in S. bovis did not affect the growth rate or formate-to-lactate ratio, suggesting that the flux in the glycolytic pathway is unlikely to be altered by GAPN activity. Streptococcus bovis GAPN was NADP+ dependent, but not phosphate dependent. In addition, S. bovis did not have other NADPH-producing systems such as the hexose monophosphate pathway and NADPH:NAD+ oxidoreductase. Therefore, GAPN may play an important role in NADPH production in S. bovis.
Sweet carbon nanostructures: carbohydrate conjugates with carbon nanotubes and graphene and their applications (2012)

Because of their unique physicochemical properties, carbon nanotubes and graphene can find promising applications in many fields of biomedical research. However, the pristine nanomaterials suffer from low solubility in aqueous systems which results in their limited biocompatibility. Through the introduction of carbohydrates, the surface properties of these graphitic carbon nanostructures can be modified not just to improve their water solubility but also to enable these versatile nanostructures to interact selectively with biological systems. This review will highlight the synthetic strategies that have been reported for the covalent and noncovalent functionalization of carbon nanostructures with carbohydrates, as well as their applications in biosensing and biomedicine.

The biliary excretion of enterokinase in rats. Studies in normal, chronic ethanol-maintained and cirrhotic rats (1981)

The excretion of catalytically active human or pig enterokinase in hepatic bile after intravenous administration to normal rats or rats that had been maintained on 20% (v/v) ethanol for 1 year showed similar kinetics to that described for other serum-derived bile proteins. The half-life in serum was 2.5 min or less, and most of the enzyme was excreted within 45 min of administration. This was maintained when up to six successive doses were given at 90 min intervals. The mean amount excreted per dose was independent of the dose number and varied from 0.8% to 2.1% in the normal animals and 1.2% to 2.0% in the chronic ethanol-maintained animals. When three doses of enzyme were given at 30 min intervals, the total amount of active enterokinase recovered in bile was dose-dependent and was consistently higher in the rats drinking 20% (v/v) ethanol. The serum half-life of enterokinase in rats made cirrhotic by inhalation of carbon tetrachloride vapour was extended to 6 min or more. The amount of active enzyme recovered in bile was at least 50% less than in weight-matched normal rats, and excretion was not complete 2h after intravenous administration. The possible significance of these findings in liver and pancreatic disease is discussed.
Mixin Composition Synthesis Based on Intersection Types (2015)

We present a method for synthesizing compositions of mixins using type inhabitation in intersection types. First, recursively defined classes and mixins, which are functions over classes, are expressed as terms in a lambda calculus with records. Intersection types with records and record-merge are used to assign meaningful types to these terms without resorting to recursive types. Second, typed terms are translated to a repository of typed combinators. We show a relation between record types with record-merge and intersection types with constructors. This relation is used to prove soundness and partial completeness of the translation with respect to mixin composition synthesis. Furthermore, we demonstrate how a translated repository and goal type can be used as input to an existing framework for composition synthesis in bounded combinatory logic via type inhabitation. The computed result corresponds to a mixin composition typed by the goal type.

Molecular Biology of Anti-α-(1→6)dextrans (1993)

α(1→6)dextrans are homopolymers of glucose with chains of α(1→6)linked glucoses generally connected by short branches with α(1→2), α(1→3) and α(1→4)linkages (1). During the 1980's extensive improvements in determining dextran structures have been made in analytical periodate structural analysis (POSA), methylation structural analysis (MSA), non-reducing end group analysis (NREG) which have made possible more exact correlations with immunochemical studies and led to an improved notation (1) as well as to the elimination of ambiguities resulting from the use of (1→6)-like instead of (1→ ) for a terminal non-reducing end and (1→6) for two possibilities. The second residue may be α(1→2)-, α(1→3)-, α(1→4)-, or α(1→6)-linked in various dextrans (cf 1). Dextran B512F which was generally given as having 95% α(1→6) and 5% α(1→3)linkages actually has 90% α(1→6), 5% α(1→ ) and 5% α(1→b) with b denoting a branch point.

The relation between birth size and the results of refractive error and biometry measurements in children (2004)

Children who were born heavier, had larger head sizes or lengths at birth, or who were born more mature had longer axial lengths, and deeper vitreous chambers; but there were no differences in refraction at ages 7-9 years, possibly because of the observed compensatory flattening of the cornea.
Comparison of two-dimensional numerical approximation and measurement of SAR in a muscle equivalent phantom exposed to a 915 MHz slab-loaded waveguide (1990)

Computer predictions of the specific absorption rate (SAR) distribution in a uniform muscle-equivalent phantom with an overlying bolus have been compared to those measured experimentally. The microwave source was a 10 cm x 10 cm slab-loaded waveguide applicator operating at 915 MHz. The modelling technique (theory) combines the equivalence principle and a two-dimensional finite element technique to determine the incident and the scattered electric fields separately. The E-field was measured using a small dipole device oriented parallel to the polarized field of the waveguide source. Comparisons of the predicted and measured SAR were made for various bolus properties, and reasonable agreement with theory was found in each case. The results demonstrate the usefulness of numerical modelling in characterizing the fields from microwave applicators used in clinical hyperthermia.

Analysis of residential thermal storage systems performance. Final report (1984)

In an effort to answer some of the technological and economic questions surrounding the use of residential thermal energy storage (TES) for load management, the Electric Energy Systems Division of the US Department of Energy, through the Oak Ridge National Laboratory, co-funded with the participating utilities, a nationwide field test program of residential TES systems. The qualitative results of these field tests have been previously reported, and have shown the concept of residential TES to be a viable load management option. However, the tests also found a variety of deficiencies in the storage equipment then available that would prevent the widespread commercialization of these systems in the residential market. With an eye towards the next generation of storage equipment, the data from these field tests were analyzed to determine equipment load characteristics, quantify the performance of the storage equipment, and identify needed improvements in equipment design and controls. This report presents the results of the analysis for residential storage air conditioning, storage space heating, and storage water heating. Conclusions are drawn and recommendations are made in the areas of improved storage equipment, application guidelines, and utility benefits.

Characterization of Adsorption of Sodium Dodecyl Sulfate on Charge-Regulated Substrates by Atomic Force Microscopy Force Measurements (1997)

The adsorption of sodium dodecyl sulfate (SDS) on gold surfaces covered with self-assembled monolayers (SAMs) of thiols made with either hexadecyl mercaptan or 2-aminoethanethiol hydrochloride was investigated by probing the surface charge. This was accomplished by determining the force between a modified (with a negatively charged silica sphere) tip of an atomic force microscope and the surface as SDS was adsorbed. The ionic nature of aqueous SDS solutions and the critical micelle concentration (cmc) in deionized water were determined by measuring the sudden change in diffuse double-layer thickness on micelle formation. The interaction between a silica probe and an initially positively charged gold substrate with a 2-aminoethanethiol layer was a strong function of SDS concentration. The phenomenon of surface charge reversal (where the amount of negative SDS equals the cationic surface charge) was directly observed at an SDS concentration of about 1/1000 cmc. The surface electrostatic potentials of the surfactant-adsorbed substrates were calculated by solving the complete nonlinear Poisson−Boltzmann equation with the knowledge of silica probe surface potentials. From the surface charge vs surfactant concentration data, the adsorption behavior of SDS was assessed. The interaction between the silica probe and the hydrophobic hexadecyl mercaptan SAM-covered gold substrate was also examined to mimic the adsorption behavior of the hydrophobic hemimicelle, which could form on the 2-aminoethanethiol surface. Considerably different surfactant adsorption behavior was found for the hydrophobic hexadecyl mercaptan SAM and the 2-aminoethanethiol surfaces. For the adsorption of SDS on an initially positively charged surface, quantitative force measurements show that the formation of a compact and uniform hemimicelle or bilayer did not occur.
