Imaging of the larynx--extending the use of stroboscopy-related techniques (2002)

Three methods (I-III) are presented to demonstrate how technical modifications in the use of stroboscopy-related techniques can be applied to further analyze vocal fold vibrations. (I) With double exposure videostroboscopy, dynamic properties of vocal folds can be visualized within one single image. This allows for estimations of horizontal vibratory velocity of the vocal fold margins. (II) Stroboscopic transillumination of the larynx makes it possible to localize initial vocal fold opening in the horizontal glottal plane and to visualize different vibratory opening patterns. Bidirectional color-coded endoscopic imaging of the larynx facilitates a semi-automated, digital measurement of the glottal area. (III) Stroboscopic illumination using four light emitting diodes (LEDs) clipped on a rigid endoscope and triggered by a portable 'pocket-sized', battery-powered electronic control device offers new prospects for performing stroboscopy outside of specialized clinical facilities.
Plasma Channel Miniature Hole Drilling Technology (2004)

With growing economic and environmental pressures, oil companies seek ways to increase the oil recovery from every well. Re-entry drilling of horizontal sidetracks from existing wells and multilateral drilling for new wells are techniques which help to achieve that increase. However, new approaches are needed to reduce the cost and to improve efficiency of rotary drilling methods used for these purposes. A new nonrotary plasma channel drilling (PCD) method for drilling of small diameter holes (3.5-15 cm) in oilfields for sidetrack creation and multilateral drilling is described in this paper. The method relies upon the use of the energy of impulse spark discharges which are formed inside the rock formation ahead of the drill position. Repeated formation of the plasma channel results in an effective and controlled drilling action. Plasma channel drills developed at Strathclyde University are able to cut clearly defined circular holes in medium hard sandstone with speeds of up to 16 cm/min using specific energies as low as 400 J/cm/sup 3/. Plasma channel drilling has the potential to increase the lifetime of oil wells and would significantly reduce the cost of exploration drilling and subsurface data acquisition. PCD technology can also be a cost-effective and practical solution for other applications such as mineral mining, water boring and scale removal where micro-hole drilling is essential.
The PKC targeting protein RACK1 interacts with the Epstein–Barr virus activator protein BZLF1 (2000)

Phorbol esters reactivate Epstein-Barr virus (EBV) from latently infected cells via transcriptional activation of the viral immediate-early gene BZLF1. BZLF1 is a member of the extended AP-1 family of transcription factors that binds to specific BZLF1-binding motifs within early EBV promoters and to consensus AP-1 sites. Regulation of BZLF1's activity is achieved at the transcriptional level as well as through post-translational modifications. Recently, we reported that the transcriptional activity of BZLF1 is augmented by TPA [Baumann, M., Mischak, H., Dammeier, S., Kolch, W., Gires, O., Pich, D., Zeidler, R., Delecluse, H. J. & Hammerschmidt, W., (1998) J. Virol. 72, 8105-8114]. The increase of BZLF1's activity depends on a single serine residue (S186) that is phosphorylated by protein kinase C (PKC) in vitro and in vivo after stimulation with 12-O-tetradecanoylphorbol-13-acetate (TPA). Here, we identified RACK1 as a binding partner of BZLF1 in a yeast interaction trap assay. RACK stands for receptor of activated C-kinase and is involved in targeting activated PKCs and other signaling proteins. In vivo, RACK1 binds directly to the transactivation domain of BZLF1. Although a functional relationship between BZLF1 and PKC could be mediated by RACKs, RACK1 did not have a detectable effect on the phosphorylation status of BZLF1 in in vitro or in vivo phosphorylation assays. We suggest that RACK1 may act as a scaffolding protein on BZLF1 independently of activated PKCs.
Secure Sharing of Partially Homomorphic Encrypted IoT Data (2017)

IoT applications often utilize the cloud to store and provide ubiquitous access to collected data. This naturally facilitates data sharing with third-party services and other users, but bears privacy risks, due to data breaches or unauthorized trades with user data. To address these concerns, we present Pilatus, a data protection platform where the cloud stores only encrypted data, yet is still able to process certain queries (e.g., range, sum). More importantly, Pilatus features a novel encrypted data sharing scheme based on re-encryption, with revocation capabilities and in situ key-update. Our solution includes a suite of novel techniques that enable efficient partially homomorphic encryption, decryption, and sharing. We present performance optimizations that render these cryptographic tools practical for mobile platforms. We implement a prototype of Pilatus and evaluate it thoroughly. Our optimizations achieve a performance gain within one order of magnitude compared to state-of-the-art realizations; mobile devices can decrypt hundreds of data points in a few hundred milliseconds. Moreover, we discuss practical considerations through two example mobile applications (Fitbit and Ava) that run Pilatus on real-world data.
Ultrasound contrast agents phagocytosed by neutrophils demonstrate acoustic activity (2003)

Ultrasound contrast agents are microbubbles composed of a thin lipid or albumin shell filled with air or a high molecular weight gas. These microbubbles are used for contrast-enhanced ultrasound (CEU) assessment of organ perfusion. In regions of inflammation, microbubbles are phagocytosed intact by activated neutrophils adherent to the venular wall. The authors hypothesized that microbubbles remain acoustically active following phagocytosis. Accordingly, they assessed the physical responses of both phagocytosed and free microbubbles by direct microscopic observation during delivery of repetitive single pulses of ultrasound at various acoustic pressures. Insonation results in oscillation in the bubbles volume. Microbubbles were optically recorded during insonation with a high-speed imaging system and diameter-time curves were analyzed to determine the effect of phagocytosis. Phagocytosed microbubbles retained their acoustic activity, although the intracellular environment increased viscoelastic damping experienced by microbubbles. With a pulse of high acoustic intensity (>1 MPa), phagocytosed microbubbles expanded up to 500% of their initial radii, which occasionally resulted in neutrophil rupture. Primary radiation force displaced phagocytosed microbubbles a distance of 100 microns with an acoustic pressure of -240 kPa and a pulse repetition frequency of 10 kHz, thus providing further evidence of acoustic activity. The authors conclude that phagocytosed microbubbles exhibit viscoelastic damping and yet are susceptible to acoustic destruction. They can generate non-linear echoes on the same order of magnitude as free microbubbles. These results indicate that CEU may be used to identify and assess regions of inflammation by detecting acoustic signals from microbubbles that are phagocytosed by activated neutrophils. In addition, the rapid expansion of a microbubble at high acoustic pressure may present a means to rupture a neutrophil or drug capsule at a specific site, resulting in delivery of a drug.
Fog Computing Platforms for Smart City Applications: A Survey (2022)

Emerging IoT applications with stringent requirements on latency and data processing have posed many challenges to cloud-centric platforms for Smart Cities. Recently, Fog Computing has been advocated as a promising approach to support such new applications and handle the increasing volume of IoT data and devices. The Fog Computing paradigm is characterized by a horizontal system-level architecture where devices close to end-users and IoT devices are used for processing, storage, and networking functions. Fog Computing platforms aim to facilitate the development of applications and systems for Smart Cities by providing services and abstractions designed to integrate data from IoT devices and various information systems deployed in the city. Despite the potential of the Fog Computing paradigm, the literature still lacks a broad, comprehensive overview of what has been investigated on the use of such paradigm in platforms for Smart Cities and open issues to be addressed in future research and development. In this paper, a systematic mapping study was performed and we present a comprehensive understanding of the use of the Fog Computing paradigm in Smart Cities platforms, providing an overview of the current state of research on this topic, and identifying important gaps in the existing approaches and promising research directions.
Dynamic Changes in Portal Vein Flow during Decongestion in Patients with Heart Failure and Cardio-Renal Syndrome: A POCUS Case Series (2021)

Evaluation of abdominal venous congestion by point-of-care ultrasound could aid in diagnosis and follow-up of patients with congestive kidney injury.
Lowering cost of test: parallel test or low-cost ATE? (2003)

Low cost ATE has often been promoted as the obvious solution to reduce the cost of test. Parallel test is another well-known approach, where multiple devices are tested on one tester (multi-site test) while multiple blocks within one device are tested concurrently. This paper shows quantitatively that parallel test reduces test cost more effectively than low-cost ATE, because it reduces all test cost contributors, not only the capital cost of ATE.
Chloride transport properties of human leukemic cell lines K562 and HL60 (1984)

The Cl- transport characteristics of the human leukemic cell lines K562 and HL60, with erythroid and granulocytic phenotypic features, respectively, were investigated. Cl- effluxes were measured with 36Cl- under equilibrium conditions in both cell lines and were found to be three orders of magnitude slower than the unidirectional efflux of Cl- in normal erythrocytes. Induction of differentiation of the K562 cell line with hemin does not affect the rate of Cl- transport, while induction of the HL60 cell line with dimethyl sulfoxide results in a small decrease in the rate of Cl- transport. Cl- transport in both cell lines could be divided into two components. One component is inhibited by treatment with 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS), displays counter-transport characteristics, and has a high energy of activation--all properties characteristic of the human erythrocyte-facilitated anion exchange system. The second component is insensitive to DIDS, is partially inhibited by furosemide, and has a low energy of activation.
Bulbar palsy in senile onset familial amyloid polyneuropathy (30Val→Met): transthyretin‐amyloid deposits in the hypoglossal nerve root (1998)

Japanese familial amyloid polyneuropathy (FAP type I) is characterized clinically by autonomic and sensorimotor polyneuropathy. Bulbar palsy or lower cranial amyloid neuropathy has not been reported in this disease. We report a 72-year-old man with senile onset FAP type I, who developed bulbar palsy and sensorimotor polyneuropathy without autonomic failures. He noticed dysesthesia and muscle weakness in the feet at the age of 67 years. Neurological examination showed bulbar signs and sensorimotor polyneuropathy, but not autonomic neuropathy. Electromyography showed denervation in the tongue and extremities. Sural nerve biopsy revealed a profound reduction of myelinated fibers. Neuropathological studies indicated axonal degeneration and transthyretin-amyloid deposits in the peripheral nerves and hypoglossal nerves or roots. DNA analysis demonstrated transthyretinMet30 mutation. We provide the novel possibility that bulbar palsy, due to amyloid neuropathy, can occur in FAP type I. Copyright Rapid Science Ltd
Structural Diversity in a Series of Alkyl-Substituted Cesium Aryloxides (2011)

A family of cesium aryloxides [Cs(OAr)](n) were synthesized and structurally characterized from the reaction of 1:1 or 1:excess stoichiometry of Cs(0) and the appropriate alkyl-substituted phenol: 2-alkylphenol [alkyl = methyl (H-oMP), isopropyl (H-oPP), and tert-butyl (H-oBP)] and 2,6-dialkylphenol [alkyl = methyl (H-DMP), isopropyl (H-DIP), tert-butyl (H-DBP), and phenyl (H-DPhP)]. The products were structurally identified as [Cs(oMP)(H-oMP)(2)](n) (1), [Cs(5)(oPP)(5)](n) (2), [Cs(4)(oBP)(4)(H-oBP)(6)](n) (3x, shown), [Cs(3)(DMP)(3)](n) (4), [Cs(2)(DIP)(2)](n) (5), [Cs(DIP)(H-DIP)](n) (5x), and [Cs(DPhP)](n) (7). Compounds 1-7 were found to adopt complex polymeric structures employing π interactions from the neighboring pendant phenoxide ligands. The solution behavior of these compounds was studied using solution (133)Cs NMR spectroscopy, and for each compound, a single (133)Cs NMR resonance was observed, with chemical shift values found to be strongly solvent-dependent. This implies that monomeric cesium salt species involving solvent interactions exist in solution.
Theoretical analysis and experimental demonstration of resonant light scattering from metal nanostrips on quartz (2008)

Using the Green's tensor area integral equation method and reflection spectroscopy, resonant light scattering from rectangular gold nanostrips on quartz substrates fabricated with electron-beam lithography is analyzed theoretically and demonstrated experimentally. Theory and experiments are compared and found in a good agreement. Design curves presenting the scattering resonance wavelength as a function of the nanostrip width allow one, by carefully choosing the strip width and thickness, to realize the resonance at a given wavelength in a broad wavelength spectrum ranging from the visible (~600 nm) to the near infrared including telecommunication wavelengths (~1600 nm).
Yb(OTf)3 and ZrCl4 Mediated Rearrangement of Alkoxybenzyl Allyl Ethers into Aldehydes&# (2004)

Lewis acid mediated rearrangement of alkoxybenzyl allyl ethers into aldehydes in moderate to good yields, catalysed either by Yb(OTf)3 or ZrCl4 is reported. The ZrCl4 catalysed transformation offers mild and easily adaptable clean reaction conditions and good yields of the products. Additionally, ZrCl4 catalysed rearrangement under solvent free conditions is an advantageous modification. Keywords: yb(otf)3, zrcl4, solvent free conditions, lewis acid catalysed rearrangement, aldehydes, naphthalene derivatives
Decision making in design process (1989)

In design process, decision making with a great choice is very difficult, and we need some kind of criterion. Sense of value, image, conceptualizing, goal and others are musually interwound, and they can not be unified. If a man acts logically, the normative model by von Neumann-Morgestern is useful in decision making. However, it is impossible for a man to act logically always. The convex dependence theory which seems to compensate man's illogicality can not also solve the actual problems. Decision making in design process is the bulletin of his total personality, and it must possesses a synthesis. The most important key-word of the synthesis is circulation. We must stop the production system with waste which can not be circulated. The authors propose a circulated production system and countermeasures for the waste.
Cutoff levels of immunoglobulin M antibody against viral core antigen for differentiation of acute, chronic, and past hepatitis B virus infections (1986)

The titer of antibody against core antigen of hepatitis B virus in the immunoglobulin M class (IgM anti-HBc) was determined by an IgM capture assay of reduced sensitivity (30 arbitrary units). The distribution of titers among 235 acute hepatitis patients who were hepatitis B surface antigen (HBsAg) positive suggested that 600 U forms a lower cutoff value for acute hepatitis B. Clinically apparent cases of acute hepatitis with high IgM anti-HBc and without HBsAg were rare (2.6%). Acute, non-B hepatitis in HBsAg carriers was more frequent (9.4%). In chronic hepatitis B, 39% of 174 biopsy-proven cases had moderate titers of 30 to 600 U, whereas healthy HBsAg carriers were rarely (4/84) positive. In mild or inapparent infections without HBsAg, titers were between 50 and 400 U. Thus, sufficiently accurate and sensitive quantitation of IgM anti-HBc allows for differentiation of acute and nonacute hepatitis B virus infection in acute hepatitis, partial differentiation between clinically symptomatic and asymptomatic chronic infections, and identification of recent subclinical infections.
Myasthenia Gravis and Acetylcholine Receptor (1975)

Lymphocytes from patients with myasthenia gravis (MG) were transformed when cultured in vitro with an acetylcholine receptor fraction extracted from the electric organ of an electric eel. Marked diminution of the cellular response to acetylcholine was shown in patients who improved clinically with prednisone treatment. The transient clinical deterioration during the first days of prednisone treatment was accompanied by a transient increase in lymphocyte response. These findings that an in vivo sensitization of lymphocytes to self-acetylcholine receptor may occur in MG, and that a cell-mediated autoimmune mechanism may be important in the pathogenesis of the neuromuscular block. The present observations indicate that prednisone provides a measure of immunosuppression in MG. The transient clinical deterioration during the first days of prednisone therapy may reflect an enhancement of cell reactivity by this drug.
Multimodal Fluorescence-Mediated Tomography and SPECT/CT for Small-Animal Imaging (2013)

The feasibility of integrating a fiber-based, video-rate FMT system with a commercial preclinical SPECT/CT platform was established. These coregistered FMT and SPECT/CT results with MOMIAs may facilitate the development of the next generation of preclinical and clinical multimodal optical-nuclear platforms for a broad array of imaging applications and help elucidate the underlying biologic processes relevant to cancer diagnosis and therapy monitoring.
High-quality multilayer graphene on an insulator formed by diffusion controlled Ni-induced layer exchange (2017)

The Ni-induced layer-exchange growth of amorphous carbon is a unique method used to fabricate uniform multilayer graphene (MLG) directly on an insulator. To improve the crystal quality of MLG, we prepare AlOx or SiO2 interlayers between amorphous C and Ni layers, which control the extent of diffusion of C atoms into the Ni layer. The growth morphology and Raman spectra observed from MLG formed by layer exchange strongly depend on the material type and thickness of the interlayers; a 1-nm-thick AlOx interlayer is found to be ideal for use in experiments. Transmission electron microscopy and electron energy-loss spectra reveal that the crystal quality of the resulting MLG is much higher than that of a sample without an interlayer. The grain size reaches a few μm, leading to an electrical conductivity of 1290 S/cm. The grain size and the electrical conductivity are the highest among MLG synthesized using a solid-phase reaction including metal-induced crystallization. The direct synthesis of uniform, high-quality MLG on arbitrary substrates will pave the way for advanced electronic devices integrated with carbon materials.
Integrating Computer Vision in Web Based Context Recognition (2006)

The analysis of documents necessitates context recognition for diverse purposes such as classification, performance analy-sis, and decision making. Traditional methods of context recognition have focused on the textual part of documents. Images, however, provide a rich source of information that can support the context recognition process. The paper pro-poses a method for integrating computer vision in context recognition using the Web as a knowledge base. The method is implemented on medical case studies to determine main symptoms or achieve possible diagnoses. Initial experiments show better results than corresponding text-only methods. 1.
Generation of tunable radiation below 2000 Å by phase-matched sum-frequency mixing in KB5O8⋅4D2O (1978)

We have investigated second harmonic generation (SHG) and sum-frequency mixing (SFG) in deuterated potassium pentaborate using N2 laser pumped dye lasers. The crystal 90° second harmonic generates at 2161.5 Å with a power conversion efficiency of 5% at an input power of 15 kW. Tunable phase-matched VUV SFG is observed from 2161.5 to 1962.4 Å. Transmission and birefringence measurements indicate that the crystal can phase match with high conversion efficiencies to below 1700 Å.
Ex situ XAS investigation of effect of binders on electrochemical performance of Li2Fe(SO4)2 cathode (2017)

With the objective of moving towards the commercialisation of Fe-based high voltage cathode Li<sub>2</sub>Fe(SO<sub>4</sub>)<sub>2</sub>, the effect of fluorinated binder (polyvinylidene fluoride – PVDF) and non-fluorinated binder (polyacrylonitrile – PAN) was evaluated.
Effect of intraarterial papaverine on cerebral circulation time. (1997)

Intraarterial papaverine produces a consistent decrease in CCT in patients with vasospasm.
Chiral Ruthenium Complexes with P,N-Ligands Derived from (S)-Proline (2001)

[Ru2(OAc)4] cleanly reacts with 2-(S)-diphenylphosphinomethylpyrrolidine (PPro) and 2-(S)-diphenylphosphinomethyl-N-methylpyrrolidine (PProMe) to give trans,trans,trans-[Ru(OAc)2(PPro)2] (2) and [Ru(OAc)2(PProMe)2], respectively, which possess stereogenic nitrogen atoms. The latter complex exists as the cis-P,P-cis-P,N-(Δ)-stereoisomer (Δ-3) in THF and as the (Λ)-stereoisomer (Λ-5) with cis-P,P-trans-N,N coordination geometry in MeOH. Formation of N-based stereocenters occurs selectively, and complexes 2, 3, and 5 are present as single epimers in solution and in the solid state. Thermolysis of Δ-3 in boiling dioxane affords (Δ)- and (Λ)-stereoisomers of the carbene ruthenium complex (7), due to facile dehydrogenation of the N-Me groups of the ligand.
New gene markers involved in regulation of granulosa cells development and differentiation towards endodermal and epithelial tissues – a new insight into the stemness specificity of ovarian follicular cells (2021)

Abstract Maintaining of female fertility is strictly dependent on proper hormonal regulation. Granulosa cells (GCs) are components of ovarian follicles, and they are important in paracrine regulation of the ovary. Preovulatory follicle GCs are responsible for production of estrogens to the ovary microenvironment and lead to the LH surge. Proper functioning of GCs is necessary to ensure appropriate conditions for oocyte development, maturation, ovulation and its release to the oviduct. Long-term in vitro culture of GCs show significant stem-like characteristics. Understanding the molecular processes underlying GCs differentiation towards different cell lineages may reveal other possible stem cell markers. A transcriptomic analysis of short-term primary in vitro cultured GCs, which were isolated from porcine preovulatory follicles was the major focus of the study. The ontological groups herby considered are associated with endodermal and epithelial tissues. Results were and compare to freshly isolated GC cells. 6 the most reduced expression: HSD17B1, DAPL1, NEBL, MAL2, DAB1, ITM2A were chosen for analysis. These genes have been response for processes associated with GCs development and differentiation towards endodermal and epithelial tissues, which make them important for further consideration.
