Multicomponent vector solitons: theory and experiment (2002)

We study, theoretically and experimentally, multicomponent spatial solitons in nonlinear saturable (isotropic and anisotropic photorefractive) bulk media. We find numerically a family of the three-component dipole-mode solitons and demonstrate their stability in a wide range of the input parameters. We also observe the formation and stability of these spatial solitons in experiment with photorefractive strontium barium niobate (SBN) crystals.

Separation of Sulphuric Acid from an Acid Suspension of Cellulose Nanocrystals by Manual Shaking (2016)

In this paper, the separation of sulphuric acid from a suspension of cellulose nanocrystal by manual shaking is described. Cellulose nanocrystals are prepared from acid hydrolysis of cotton using 64 wt% sulphuric acid at ca. 45 °C for 45 minutes. After the hydrolysis was complete, water was added to dilute the mixture to a resulting concentration of 30 wt% of the acid. This mixture was shaken rigorously in a closed container and after 48 hours, separation occurs such that cellulose nanocrystals float, with the bubbles introduced by the shaking, to give clear acid solution at the bottom. This shaking-floating process is repeatable for several cycles after the acid was removed from the bottom and more water was added. Using this simple process, the total acid recovery of > 90% has been achieved, and the concentration of all the acid recovered combined was 17.5 wt%. This work demonstrates a method that allows energy efficient and up-scalable separation of cellulose nanocrystals from the acidic suspension from which it was extracted.
AIRDRUMS: VIRTUAL DRUM KIT (2015)

Gestural based interfaces have been widely researched over the last decades, with promising results especially found and implemented in the field of artificial reality. In keeping with this desire to create immersive experiences using technology, we have created a virtual drum kit to be used in the personal space of a user, with the possibility of ultimately creating an interactive musical learning game - AirDrums. This application, based on a Natural User Interface, can be used for practice or for fun by anyone who wants to play drums, while not being appropriate for professional drummers. Users can play a track of their choice in the background and try to jam along with it, or try to create an interesting track through the recording feature and use that with other songs or rhythms. AirDrums was implemented in two versions, a direct playback solution and a NAudio solution, and was assessed empirically by 12 testers, 9 men and 3 women, aged between 18 and 28. The final NAudio version has an improved accuracy of 80% and more, depending on rhythm. Both solutions were subjectively evaluated as fun, easy to master, and affording a comfortable posture, similar to a real drummer. The main limitation consists in the fact that the application cannot replicate some of the hand movements used for real drum kits, such as placing a hand across the other, as well as much faster strikes. AirDrums can be used as a standalone application or as an element in larger e-learning games and platforms.
Short-term metabolic effects of isradipine and metoprolol in pre-eclampsia (1999)

An Initial Discussion of Timing Considerations Raised During Development of a Magician-Robot Interaction (2014)

In this work-in-progress paper, we present our development of a magician-robot interaction for a theatrical stage performance and discuss our encounters with timing and chronology concerns at a variety of scales. We describe a system for choreographing robot movement, our design observations for cueing between robot and human, and timing considerations specific to artistic and logistic concerns for a production of this type.
Hydroxyurea therapy lowers TCD velocities in children with sickle cell disease (2006)

HU-treated patients experienced statistically significant decreases in TCDi velocities compared to age-matched controls. Changes in hematologic parameters were not predictive of changes in TCDi velocities in the treated group. The decrease in TCDi velocities is not a consequence of changes in hematologic values in patients treated with HU.
Monoclonal antibodies to the major feline allergen <i>Fel d</i> I. II. Single step affinity purification of <i>Fel d</i> I, N-terminal sequence analysis, and development of a sensitive two-site immunoassay to assess <i>Fel d</i> I exposure. (1988)

Abstract Two mAb were used to develop new techniques for the purification and quantitation of the major feline salivary allergen, Felis domesticus allergen I (Fel d I). The allergen was purified from aqueous house dust extract with a high Fel d I content by affinity chromatography over a monoclonal immunosorbent and elution with 4 mM HCl, pH 2.5. This single step procedure gave 40 to 50% recovery of 90% pure allergen which, following final purification by size exclusion HPLC, showed a single line on immunodiffusion and crossed immunoelectrophoresis against monospecific anti-Fel d I and polyclonal anti-cat dander antibodies. The m.w. of native Fel d I was 39,000 on size exclusion HPLC, and 17,000 under nonreducing conditions on gel electrophoresis. The N-terminal amino acid sequence (33 residues) showed no homology with other known protein sequences. The combination of the SDS-PAGE and N-terminal sequence data suggests that Fel d I is a non-covalently linked homodimer. A two-site RIA was developed using mAb directed against different epitopes on Fel d I. This assay was species-specific, highly sensitive (0.0004 U/ml), and showed an excellent correlation with a polyclonal inhibition RIA (n = 27, r = 0.93, p less than 0.001). Cat allergen extracts used for immediate skin tests showed marked differences in Fel d I content (from 0.1 to 30 U/ml). Consistently high Fel d I levels were found at monthly intervals in six dust samples from four houses with cats (10 to 100 mu/g of dust). Comparisons of Fel d I and mite and pollen allergen levels showed that house dust can contain greater than 100 micrograms/g of either of these allergens and is a potent source of foreign environmental antigens. Monoclonal affinity chromatography provides a major breakthrough in the purification of Fel d I, from a source material that would otherwise have been considered impossible (house dust). The mAb assay for Fel d I is both more sensitive and more easily standardized than existing techniques. These techniques will allow full structural and antigenic analysis of Fel d I and more detailed studies on the relationship between cat antigen exposure and the development of asthma.
Development of Silicon Heterojunction Metal Wrap through Solar Cells (2014)

A silicon heterojunction solar cell basing on amorphous and crystalline silicon is combined with the metal wrap through technology. In this way, the geometrical front side metallization area is reduced from about 7 % to below 5 %. The novel cell concept bases on a back junction configuration to avoid complex insulation steps within the via holes. Furthermore, well-passivated via holes are fabricated in a 532 nm laser process after the thin film depositions. As an alternative, the 1064 nm laser process is investigated, however, the result is a high surface recombination rate and a low effective carrier lifetime in the via vicinity. Scanning electron microscopy cross sections of via holes indicate a different surface oxide formation for both laser lines and this result suggests that this oxidation is crucial for the via hole passivation. Via holes in silicon heterojunction solar cells also have very high surface recombination, when the via hole formation is performed prior to wet chemical cleaning and texturing steps, which is the standard sequence in diffused emitter metal wrap through solar cells. The via metallization bases on a novel low-temperature silver paste, which is deposited by vacuum assisted screen printing. Cross sections reveal excellent via filling, which results in a low electrical resistance. The via-related specific solar cell series resistance is below 80 mΩcm2. Finally, the solderability of the rear side metallization was evaluated for later module integration.

Both donor and recipient NOD2/CARD15 mutations associate with transplant-related mortality and GvHD following allogeneic stem cell transplantation (2004)

Single nucleotide polymorphisms (SNPs) of the NOD2/CARD15 gene resulting in a diminished nuclear factor-kappaB (NF-kappaB) response to bacterial cell wall products have been associated with an increased incidence of Crohn disease. To assess a possible contribution of NOD2/CARD15 mutations to graft-versus-host disease (GvHD) and complications following allogeneic stem cell transplantation, we retrospectively typed DNA from donor/recipient pairs in 169 consecutive patients receiving transplants from related or unrelated donors. Mutated alleles were observed in 21% of patients and in 14% of donors. Cumulative incidence of 1-year, transplant-related mortality rose from 20% in donor/recipient pairs without mutated SNPs to 49% in pairs with recipient mutations (P =.03) and 59% in pairs with donor mutations (P <.005), and was highest in 12 pairs with mutated alleles in both donor and recipients (83%; P <.001). Similar associations were observed for severe overall and severe gastrointestinal GvHD. The impact of NOD2/CARD15 mutations was more prominent for HLA-identical sibling transplantations but was also observed in unrelated donor transplantation. Mutations proved to be independent risk factors for transplant-related mortality. Our findings indicate a major role of monocyte/macrophage dysfunction in the pathophysiology of GvHD and strongly suggest a future risk assessment or even donor selection through NOD2/CARD15 typing.
Computational Forensic Techniques for Intellectual Property Protection (2004)

Computational forensic engineering (CFE) aims to identify the entity that created a particular intellectual property (IP). Specifically, our goal is to identify the synthesis tool or compiler which was used to produce a specific design or program. Rather than relying on watermarking content or designs, the generic CFE methodology analyzes the statistics of certain features of a given IP and quantizes the likelihood that a well known source has created it. In this paper, we describe the generic methodology of CFE and present a set of techniques that, given a set of compilation tools, identify the one used to generate a particular hardware/software design. The generic CFE approach has four phases: 1) feature and statistics data collection; 2) feature extraction; 3) entity clustering; and 4) validation. In addition to IP protection, the developed CFE paradigm can have other potential applications: optimization algorithm selection and tuning, benchmark selection, and source-verification for mobile code.
Causes, magnitude, and effects of temperature fluctuations (flickering) of catalytic wires and gauzes (1974)

Abstract An experimental study has confirmed a theoretical prediction that, when an exothermic mass transfer limited chemical reaction occurs on a single catalytic wire for which the parameter a [Equation (11)] is large, temperature fluctuations (flickering) of large amplitude must be induced by concentration fluctuations. A simplified model is presented for predicting the magnitude of flickering in industrial convertors for which the parameter a is usually large. The model should be useful in estimating the influence of improved mixing of the reactants on the reduction in precious metal loss from the gauze.

Chemoprevention of DMBA-induced Mammary Carcinogenesis: Relationship Between Induction of Phase II Enzymes, Effects on DMBA-induced Hemoglobin Adducts and Decreases in Mammary Tumor Multiplicity (2000)

Abstract The chemopreventive potential of 1,2-dithiole-3-thione, ethoxyquin, butylated hydroxanisole (BHA) and β-naphthoflavone (BNF) was investigated in the 7,12-dimethylbenz(a)anthracene (DMBA) rat mammary tumor model. Female Sprague-Dawley rats received a single dose of DMBA (15 mg) at 50 days of age. Chemopreventive agents were administered via the diet, beginning one week prior to DMBA dosing and continuing until one week following DMBA. Tumor latency, multiplicity and incidence were not affected by BHA (2.5 or 5.0 g/kg diet), but administration of low or high doses of β-napthflavone (1.65 and 3.3 g/kg diet), or high doses of ethoxyquin (5.0 g/kg diet) or 1,2-dithiole-3-thione (0.6 g/kg diet), effectively inhibited all parameters of tumorigenesis. It is presumed that many of these agents which decrease the tumorigenicity act by altering the metabolism of the carcinogen resulting in diminished numbers of reactive ultimate carcinogens. We examined both for the induction of enzymes that might alter carcinogen metabolism as well as alterations in levels of DMBA adducts to hemoglobin. A strong correlation was observed between the effect of these agents on carcinogenesis and the induction of phase I1 enzymes (quinone reductase and glutathione S-transferase) and glutathione in the mammary gland. We also examined the effects of BNF, 1.2- dithiol-3-thione and BHA on formation of hemoglobin adducts by DMBA. Similarly to the results on carcinogenesis the relative efficacy of compounds in inhibiting DMBA adduct formation and DMBA induced mammary tumorigenesis was BNF > 1,2 Dithiolthione >> BHA. These results support the hypothesis that these agents work by altering metabolism of DMBA to reactive intermediates but further offer the possibility that modulation of hemoglobin adducts may serve as a surrogate marker of efficacy.
Deletion of Smad2 in Mouse Liver Reveals Novel Functions in Hepatocyte Growth and Differentiation (2005)

Smad family proteins Smad2 and Smad3 are activated by transforming growth factor β (TGF-β)/activin/nodal receptors and mediate transcriptional regulation. Although differential functional roles of Smad2 and Smad3 are apparent in mammalian development, the relative functional roles of Smad2 and Smad3 in postnatal systems remain unclear. We used Cre/loxP-mediated gene targeting for hepatocyte-specific deletion of Smad2 (S2HeKO) in adult mice and generated hepatocyte-selective Smad2/Smad3 double knockouts by intercrossing AlbCre/Smad2(f/f) (S2HeKO) and Smad3-deficient Smad3ex8/ex8 (S3KO) mice. All strains were viable and had normal adult liver. However, necrogenic CCL4-induced hepatocyte proliferation was significantly increased in S2HeKO compared to Ctrl and S3KO livers, and transplanted S2HeKO hepatocytes repopulated recipient liver at dramatically increased rates compared to Ctrl hepatocytes in vivo. Using primary hepatocytes, we found that TGF-β-induced G(1) arrest, apoptosis, and epithelial-to-mesenchymal transition in Ctrl and S2HeKO but not in S3KO hepatocytes. Interestingly, S2HeKO cells spontaneously acquired mesenchymal features characteristic of epithelial-to-mesenchymal transition (EMT). Collectively, these results demonstrate that Smad2 suppresses hepatocyte growth and dedifferentiation independent of TGF-β signaling. Smad2 is not required for TGF-β-stimulated apoptosis, EMT, and growth inhibition in hepatocytes.
Adefovir dipivoxil resistance patterns in patients with lamivudine-resistant chronic hepatitis B (2009)

Although most patients showed virological breakthrough because of the well known rtA181V/T and rtN236T substitutions, more complex patterns were also found. ADV monotherapy, dose reduction and suboptimal virological response after 48 weeks of therapy were significantly associated with ADV resistance.
ACTS and OLYMPUS propagation experiments (1988)

The OLYMPUS and ACTS satellites both provide opportunities for 10 to 30 GHz propagation measurements. The spacecraft are sufficiently alike that OLYMPUS can be used to test some prototype ACTS equipment and experiments. Data are particularly needed on short term signal behavior and in support of uplink power control and adaptive forward error correction (FEC) techniques. The Virginia Tech Satellite Communications Group has proposed a set of OLYMPUS experiments including attenuation and fade rate measurements, data communications, uplink power control, rain scatter interference, and small-scale site diversity operation. A digital signal processing receiver for the OLYMPUS and ACTS beacon signals is being developed.
Blood–Brain Phenylalanine Relationships in Persons With Phenylketonuria (2000)

In usual cases, intellectually normal persons who have never been treated but who have a biochemical profile consistent with classical PKU exhibit lower brain levels of Phe. Such individuals are exceptional and may not need the vigorous restriction of their blood Phe levels that is required by the majority of persons with PKU.

Detergent-Solubilized RNA Polymerase from Cells Infected with Foot-and-Mouth Disease Virus (1967)

The foot-and-mouth disease virus RNA polymerase complex was dissociated from cellular membranes with deoxycholate in the presence of dextran sulfate. The soluble polymerase complex was active in the cell-free synthesis of virus-specific RNA; solubilization of the complex permitted direct analysis of the cell-free reaction mixtures without recourse to RNA extraction. A major RNA-containing component found early during cell-free incubation ranged from approximately 140 to 300S. The final major products of the cell-free system were 37S virus RNA, 20S ribonuclease-resistant RNA, and a 50S component containing RNA.
Purification and Properties of Mammalian 5’-Methylthioadenosine Phosphorylase and Bacterial 5’-Methylthioadenosine Nucleosidase: Pharmacological Implications and Perspectives (1986)

RELATION OF IRON SALTS TO INHIBITION OF GLYCOLYSIS BY THEILER FA VIRUS OF MOUSE ENCEPHALOMYELITIS (1947)

1. Brain homogenates of mice infected with the Theiler FA strain of mouse encephalomyelitis virus show marked inhibition of glucose phosphorylation. 2. A similar effect can be obtained by incubating normal brain homogenates with small amounts of ferrous sulfate. 3. Partially purified preparations of Theiler FA virus contain iron in amounts corresponding to their inhibitory effect on brain glycolysis. The virus preparations were purified by chemical fractionation and differential centrifugation and were dialyzed against potassium cyanide or pyrophosphate and potassium chloride for several days before they were analyzed for iron content. 4. The inhibitory effect of the virus preparations and of ferrous sulfate has been shown to be dependent on a heat-labile factor present in normal brain ("inactivating factor"). 5. The glycolytic activity of brain homogenates of mice infected with the Theiler FA virus can be restored by addition of a factor prepared from rabbit muscle extract. This "restoring factor" is non-dialyzable and is heat-labile. It has no hexokinase or phosphohexokinase activity. Its restoring activity is destroyed by the "inactivating factor" present in brain.
