Key Considerations and Experience Using the Ultra Low Power Sensium Platform in Body Sensor Networks (2009)

A body-worn monitor termed the LifePebble has been developed for real-time measurement of ECG, heart rate, physical activity (3 axis accelerometer) and optionally skin temperature. The LifePebble incorporates the SensiumTM system-on-chip platform designed specifically for wireless body sensor networks, and achieves robust and reliable operation in a compact and lightweight form factor. An initial target application is described; the real-time measurement of energy expenditure, to encourage positive lifestyle changes for early stage type-2 diabetic patients. This paper describes issues encountered during the design of the LifePebble, particularly related to the ambulatory application environment, and describes techniques developed to ensure reliable operation under such conditions.
Identification and functional analyses of novel antioxidant peptides and antimicrobial peptides from skin secretions of four East Asian frog species (2017)

In the present study, we identified 50 peptides that are classified into 21 peptide families with antioxidant and/or antimicrobial activity from Amolops daiyunensis, Pelophylax hubeiensis, Hylarana maosuoensis and Nanorana pleskei, which belong to four different genera in the Ranidae and Dicroglossidae families. These four frog species were found for the first time to express antioxidant peptides (AOPs) and antimicrobial peptides (AMPs). These peptides include seven newly discovered families daiyunin-1, daiyunin-2, daiyunin-3, maosonensis-1MS1, pleskein-1, pleskein-2, and pleskein-3. Antioxidant and antimicrobial activity assays showed that some of these peptides have good biological activities. For example, at a concentration of 50 μM, nigroain-B-MS1, and nigroain-C-MS1 both exhibited relatively strong 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonicacid) (ABTS) free radical scavenging ability, with eradication rates of 99.7% and 68.3% (nigroain-B-MS1), and 99.8% and 58.3% (nigroain-C-MS1), respectively. These peptides are potential candidates for the development of novel antioxidant or AMP preparations.
Susceptibility to Asbestos-Induced and Transforming Growth Factor- <b>β1</b> –Induced Fibroproliferative Lung Disease in Two Strains of Mice (2002)

Pulmonary fibrosis (PF) is caused by a number of inhaled agents, as well as by some drugs and toxic particles. The elaboration of certain peptide growth factors is thought to be key to the development of this disease process. In addition, genetic susceptibility plays a role in the development of PF. For instance, we have previously shown that the 129J strain of mice is resistant, whereas the C57BL/6 strain is highly susceptible, to asbestos-induced fibrosis. To pursue this further, in one mouse model, we crossed the 129J strain to the C57BL/6 strain to produce an F1 generation and subsequently backcrossed the F1 mice to the inbred founders. This backcross to the 129 inbred strain produced reverse similar 25% of the offspring with a phenotype that was protected from the fibrogenic effects of inhaled asbestos fibers. In the second model, both strains of mice were treated intratracheally with an adenovirus vector (AdV), which transduces expression of active transforming growth factor (TGF)-beta(1) in the lungs, producing fibroproliferative lung disease. Compared with C57 mice, a significant number of 129 strain mice exhibited at least a 1-wk delay in the fibroproliferative response to TGF-beta(1) expression at three concentrations of virus. These findings suggest that certain sequences in a gene or a cluster of genes in the 129 mouse strain impart a phenotype in which there is a delay in, or protection from, the development of lung fibrogenesis.
Deformation of the Lamina Cribrosa and Anterior Scleral Canal Wall in Early Experimental Glaucoma (2003)

Both plastic (permanent) and hypercompliant deformation of the lamina cribrosa and anterior scleral canal wall are present in young adult monkey eyes with early experimental glaucoma. These findings suggest that damage to the ONH connective tissues occurs early in the monkey model of experimental glaucoma.
Isolation and transcriptional characterization of three genes which function at start, the controlling event of the Saccharomyces cerevisiae cell division cycle: CDC36, CDC37, and CDC39. (1983)

The genes CDC36, CDC37, and CDC39, thought to function in the cell division control process in Saccharomyces cerevisiae, were isolated from a recombinant plasmid library prepared by partial digestion of S. cerevisiae genomic DNA with Sau3A and insertion into the S. cerevisiae-Escherichia coli shuttle vector YRp7. In each case, S. cerevisiae DNA sequences were identified which could complement mutant alleles of the gene in question and which could direct integration of a plasmid at the chromosomal location known to correspond to that gene. Complementing DNA segments were subcloned to remove extraneous coding regions. The coding regions corresponding to CDC36, CDC37, and CDC39 were then identified and localized by R-loop analysis. The estimated sizes of the three coding regions were 615, 1,400, and 2,700 base pairs, respectively. Transcriptional orientation of the coding regions was established by using M13 vectors to prepare strand-specific probes followed by hybridization to blots of electrophoresed S. cerevisiae mRNA. The intracellular steady-state abundance of the mRNA species corresponding to the genes was estimated by comparing hybridization signals on RNA blots to that of a previously determined standard, the cell cycle start gene CDC28. The quantities calculated for the three mRNA species were low, ranging from 1.5 +/- 1 copies per haploid cell for the CDC36 mRNA to 3.1 +/- 1.5 and 4.6 +/- 2 copies per haploid cell for the CDC37 and CDC39 mRNAs, respectively. The CDC28 mRNA had been previously estimated at 7.0 +/- 2 copies per cell.
Fundamentals of the cyclic short-time variation of indoor power-line channels (2005)

In this paper, indoor power-line channels properties are analyzed. The focus is put on the short-term variation that channel exhibits due to the behavior of electrical devices, which is influenced by the presence of mains voltage. Devices high-frequency parameters are time-varying and this makes the channel varies as well. To characterize this behavior it is proposed a model with an LPTV system and cyclostationary noise. In addition, examples of measurements corresponding to actual channels that illustrate these features are shown. More quantitative measurements results performed according to this channel model are presented in JA Cortes, et al. (2005).

Molecular basis of the structure and function of H1 hemagglutinin of influenza virus (2012)

Influenza virus hemagglutinin (HA) contains antigenic sites recognized by the host immune system, cleavage sites cleaved by host proteases, receptor binding sites attaching to sialyl receptors on the target cell, and fusion peptides mediating membrane fusion. Change in an amino acid(s) in these sites may affect the potential of virus infection and spread within and between hosts. Influenza viruses with H1 HA infect birds, pigs and humans and have caused two of the four pandemics in the past 100 years: 1918 pandemic that killed 21-50 million people and 2009 pandemic that caused more than 18,000 deaths. Understanding the relationship between antigenic structure and immune specificity, the receptor binding specificity in virus transmission, how the cleavage site controls pathogenicity, and how the fusion peptide causes membrane fusion for the entry of influenza virus into the host cell should provide information to find more effective ways to prevent and control influenza.
Motion estimation and DCT pruning: a combined approach to video coding (2002)

In the present communication an approach to the performance optimization of an H.261 implementation is described. Discrete Cosine Transform (DCT) coefficient pruning is employed and its effect on motion estimation strategies is studied. This interplay produces some very interesting experimental results on the trade-off between quality and speed of video coding.

Altering infrared metamaterial performance through metal resonance damping (2009)

Infrared metamaterial design is a rapidly developing field and there are increasing demands for effective optimization and tuning techniques. One approach to tuning is to alter the material properties of the metals making up the resonant metamaterial to purposefully introduce resonance frequency and bandwidth damping. Damping in the infrared portion of the spectrum is unique for metamaterials because the frequency is on the order of the inverse of the relaxation time for most noble metals. Metals with small relaxation times exhibit less resonance frequency damping over a greater portion of the infrared than metals with a longer relaxation time and, subsequently, larger dc conductivity. This leads to the unexpected condition where it is possible to select a metal that simultaneously increases a metamaterial’s bandwidth and resonance frequency without altering the geometry of the structure. Starting with the classical microwave equation for thin-film resistors, a practical equivalent-circuit model is developed predicting the sensitivity of infrared metamaterials to complex film impedance. Several full-wave electromagnetic models are developed to validate the resonant-circuit model, and excellent agreement is demonstrated between modeled and measured results.
Embedded thin film resistors, capacitors and inductors in flexible polyimide films (2002)

The High Density Electronics Center (HiDEC) at the University of Arkansas is working with the Sheldahl MCM-L Consortium and Rensselaer Polytechnic Institute (RPI) to develop low-cost embedded resistors, capacitors, and inductors in flexible polyimide films under an ARPA contract. Embedding thin-film passive devices into polyimide layers as part of a Multichip Module (MCM) system is new. The design concept allows fabrication and testing of embedded passive devices before assembling them into an MCM-L substrate. Embedded passive devices are needed as an enhancement to present day MCM-L and MCM-D technologies. The ability to remove devices such as terminating resistors and decoupling capacitors from the surfaces of PCB boards and MCMs into a flexible film, at low cost, would be a break-through for MCM technology. The devices are made into a flexible MCM package using a 2 layer interconnect system called the Interconnected Mesh Power System (IMPS) developed and patented at the University of Arkansas. The IMPS interconnection topology incorporates fine line lithography and batch via generation to allow planar power and ground distribution, and dense signal interconnection, on only two metal layers. The materials being used are NiCr, TaN, and CrSi for the resistors and Ta/sub x/O/sub y/ and BaTiO/sub x/ for the capacitors. Contacts, interconnecting signal lines, and power lines are made with Cu metallurgy. The devices are made on a 25 /spl mu/m or 50 /spl mu/m thick polyimide film and are encapsulated with the same polyimide.
The use of glycaemic index tables to predict glycaemic index of composite breakfast meals (2004)

The applicability of the glycaemic index (GI) in the context of mixed meals and diets is still debatable. The objective of the present study was to investigate the predictability of measured GI in composite breakfast meals when calculated from table values, and to develop prediction equations using meal components. Furthermore, we aimed to study the relationship between GI and insulinaemic index (II). The study was a randomised cross-over meal test including twenty-eight healthy young men. Thirteen breakfast meals and a reference meal were tested. All meals contained 50 g available carbohydrate, but differed considerably in energy and macronutrient composition. Venous blood was sampled for 2 h and analysed for glucose and insulin. Prediction equations were made by regression analysis. No association was found between predicted and measured GI. The meal content of energy and fat was inversely associated with GI (R(2) 0.93 and 0.88, respectively; P<0.001). Carbohydrate content (expressed as percentage of energy) was positively related to GI (R(2) 0.80; P<0.001). Using multivariate analysis the GI of meals was best predicted by fat and protein contents (R(2) 0.93; P<0.001). There was no association between GI and II. In conclusion, the present results show that the GI of mixed meals calculated by table values does not predict the measured GI and furthermore that carbohydrates do not play the most important role for GI in mixed breakfast meals. Our prediction models show that the GI of mixed meals is more strongly correlated either with fat and protein content, or with energy content, than with carbohydrate content alone. Furthermore, GI was not correlated with II.
Square-Wave Operation for a Single-Phase-PFC Three-Phase Motor Drive System Without a Reactor (2011)

This paper proposes a square-wave control strategy for a single-phase power factor correction with a new boost-up converter which uses the leakage inductance of a motor instead of a boost-up reactor. Since the power supply is connected to the neutral point of the motor, the current distortion in the power supply occurs when the inverter outputs square waveforms. First, this paper describes the characteristic of the proposed circuit and the problems in the square-wave operation. Next, a current control method for the square waveform is proposed to suppress the current distortion. Finally, the validity of the proposed converter and its control strategy are demonstrated by experimental results.
Modulation technique for measuring diffusion coefficients of Ba in noble gases (1987)

The diffusion coefficient of Ba (6s5d 3DJ) in noble gases was measured with a modulation/lock-in technique. This technique relies on a cylindrically symmetric source for the metastable state, and is independent of cell geometry. It is readily generalizable to other systems where the creation rate of a long-lived state can be modulated.
Effects of mechanical tension on protrusive activity and microfilament and intermediate filament organization in an epidermal epithelium moving in culture. (1986)

Mechanical tension influences tissue morphogenesis and the synthetic, mitotic, and motile behavior of cells. To determine the effects of tension on epithelial motility and cytoskeletal organization, small, motile clusters of epidermal cells were artificially extended with a micromanipulated needle. Protrusive activity perpendicular to the axis of tension was dramatically suppressed. To determine the ultrastructural basis for this phenomenon, cells whose exact locomotive behavior was recorded cinemicrographically were examined by transmission electron microscopy. In untensed, forward-moving lamellar protrusions, microfilaments appear disorganized and anisotropically oriented. But in cytoplasm held under tension by micromanipulation or by the locomotive activity of other cells within the epithelium, microfilaments are aligned parallel to the tension. In non-spreading regions of the epithelial margin, microfilaments lie in tight bundles parallel to apparent lines of tension. Thus, it appears that tension causes alignment of microfilaments. In contrast, intermediate filaments are excluded from motile protrusions, being confined to the thicker, more central part of the cell. They roughly follow the contours of the cell, but are not aligned relative to tension even when microfilaments in the same cell are. This suggests that the organization of intermediate filaments is relatively resistant to physical distortion and the intermediate filaments may act as passive structural support within the cell. The alignment of microfilaments under tension suggests a mechanism by which tension suppresses protrusive activity: microfilaments aligned by forces exerted through filament-surface or filament-filament interconnections cannot reorient against such force and so cannot easily extend protrusions in directions not parallel to tension.
Age‐related maculopathy in the light of ischaemia (2007)

This manuscript focuses on the pathogenesis of age-related maculopathy (ARM) and the documentation of new treatments in ARM. Ischaemia will be given special consideration, as it is believed to play a central role in both early ARM and late ARM or age-related macular degeneration (AMD). Reduced choroidal and retinal blood flow causes ischaemia of Bruch's membrane, retinal pigment epithelium and neuroretina in the early course of ARM. This is thought to be the primary trigger of the condition. Chronic ischaemia upregulates vascular endothelial growth factor (VEGF), which induces abnormal vessel growth in neovascular AMD. The role of ischaemia in neovascular AMD is supported by the evidence of effective new treatments targeting VEGF.

A Web-based, event-driven management architecture (1999)

Trends in the network management product industry are to incrementally enhance traditional centralized management systems with Web-based user interfaces, which mainly resolve the distributed information browsing. Some of the main deficiencies of such systems are their inability to carry out real-time event processing and alarm, and their security. So we believe pure and integrated Web-based network management means more. In this paper, we first investigate two popular Web-based network management models, i.e. two-tier model and three-tier model. And then we present a network management architecture, WebView/98, based on the three-tier model, aiming to realize distributed network management by adopting Web and Java technology, and incorporating traditional standard network management protocols, such as SNMP and CMLP. The WebView/98 approach addresses the outlined key limitations of today's Web-based network management system by introducing the event-driving coordinator, trusted domain, certificate-based authentication, and the role-based authorization mechanism.

Real‐Time Monitoring of Phosphorylation Kinetics with Self‐Assembled Nano‐oscillators (2015)

Phosphorylation is a post-translational modification that is involved in many basic cellular processes and diseases, but is difficult to detect in real time with existing technologies. A label-free detection of phosphorylation is reported in real time with self-assembled nano-oscillators. Each nano-oscillator consists of a gold nanoparticle tethered to a gold surface with a molecular linker. When the nanoparticle is charged, the nano-oscillator can be driven into oscillation with an electric field and detected with a plasmonic imaging approach. The nano-oscillators measure charge change associated with phosphorylation of peptides attached onto a single nanoparticle, allowing us to study the dynamic process of phosphorylation in real time without antibodies down to a few molecules, from which Michaelis and catalytic rate constants are determined.
Gold Thione Complexes (2014)

The reaction of the ligand Et4todit (4,5,6,7-Tetrathiocino-[1,2-b:3,4-b']-diimidazolyl-1,3,8,10-tetraethyl-2,9-dithione) with gold complexes leads to the dinuclear gold(I) complexes [{Au(C6F5)}2(Et4todit)] and [Au(Et4todit)]2(OTf)2, which do not contain any gold-gold interactions, or to the gold(III) derivative [{Au(C6F5)3}2(Et4todit)]. The crystal structures have been established by X-ray diffraction studies and show that the gold centers coordinate to the sulfur atoms of the imidazoline-2-thione groups.
Primary-Structure Determination of Fourteen Neutral Oligosaccharides Derived from Bronchial-Mucus Glycoproteins of Patients Suffering from Cystic Fibrosis, Employing 500-MHz 1H-NMR Spectroscopy (1982)

The structure of carbohydrate units of bronchial-mucus glycoproteins obtained from cystic fibrosis patients was investigated by 500-MHz 1H-NMR spectroscopy and methylation analysis. To that purpose, the mucin was subjected to alkaline borohydride degradation. Neutral oligosaccharide-alditols, ranging in size from disaccharides to pentasaccharides, were isolated. Eight compounds could be purified to homogeneity; furthermore, three fractions were obtained consisting mainly of two components. For all 14 compounds the primary structure could be elucidated. 500-MHz 1H-NMR spectroscopy was found to be effective in detecting heterogeneity and to be invaluable for the determination of structures in mixtures of oligosaccharide-alditols. The structures can be divided into two groups depending on the core disaccharide. One group contains Gal(beta 1 leads to 3)GalNAc-ol as common structural element, the other GlcNAc(beta 1 leads to 3)GalNAc-ol. Both disaccharides were identified as such; the other compounds can be conceived as extensions thereof. The most complex representatives of the two groups are: (formula; see text) The italicized structural elements, comprising the SSEA-1 determinant and the type-1 blood-group-H determinant, are novel sequences in oligosaccharide chains of mucin-type glycoproteins.
