Modeling the Maximum Spreading of Liquid Droplets Impacting Wetting and Nonwetting Surfaces (2016)

Droplet impact has been imaged on different rigid, smooth, and rough substrates for three liquids with different viscosity and surface tension, with special attention to the lower impact velocity range. Of all studied parameters, only surface tension and viscosity, thus the liquid properties, clearly play a role in terms of the attained maximum spreading ratio of the impacting droplet. Surface roughness and type of surface (steel, aluminum, and parafilm) slightly affect the dynamic wettability and maximum spreading at low impact velocity. The dynamic contact angle at maximum spreading has been identified to properly characterize this dynamic spreading process, especially at low impact velocity where dynamic wetting plays an important role. The dynamic contact angle is found to be generally higher than the equilibrium contact angle, showing that statically wetting surfaces can become less wetting or even nonwetting under dynamic droplet impact. An improved energy balance model for maximum spreading ratio is proposed based on a correct analytical modeling of the time at maximum spreading, which determines the viscous dissipation. Experiments show that the time at maximum spreading decreases with impact velocity depending on the surface tension of the liquid, and a scaling with maximum spreading diameter and surface tension is proposed. A second improvement is based on the use of the dynamic contact angle at maximum spreading, instead of quasi-static contact angles, to describe the dynamic wetting process at low impact velocity. This improved model showed good agreement compared to experiments for the maximum spreading ratio versus impact velocity for different liquids, and a better prediction compared to other models in literature. In particular, scaling according to We(1/2) is found invalid for low velocities, since the curves bend over to higher maximum spreading ratios due to the dynamic wetting process.
Simultaneous screech tone modes of an axially symmetric jet (1989)

The screech frequency of axially symmetric choked jets falls steadily with decreasing pressure ratio, with several frequency jumps, some up, some down [A. Powell, Proc. Phys. Soc. London Ser. B 66, 1039-1056 (1953)]. Davies and Oldfield's Lissajous figures [Acustica 12, 267–277 (1962)] showed that the corresponding jet oscillation modes are of various types. Schlieren photography and digitally processed acoustic pressure signals are now used. Unambiguously, the first two modes, a1 and a2, are axially symmetric (varicose, like ring vortices); the next, b, is asymmetric in an arbitrary plane (sinuous); c is helical, rotating in either sense, stable once started, while d is sinuous again, connected to c by hysterectic jumps. However, tone d is weakly but smoothly connected to b, so d appears to be an extension of b. Moreover, the dominant c tone extends weakly to overlap where b and d dominate, and a suspected weak a2(?) overlaps where b, c, and d dominate. Further, both a1 and b exist weakly where a2 dominates. Evidently jumps occur not necessarily at changes in the mode as previously thought, but when there is a change in which one dominates.

Optimal Diversity-Multiplexing Tradeoff With Group Detection for MIMO Systems (2005)

It is well known that multiple-input multiple-output (MIMO) systems provide two types of gains: diversity gains and spatial multiplexing gains. Recently, a tradeoff function of these two gains has been derived for a point-to-point MIMO system when optimal detection is used. In this paper, we extend the previous work to a more general MIMO system, where the transmitted data is coded in groups. Group detection is applied at the receiver to retrieve the data. It consists of a zero-forcing decorrelation that separates the groups, followed by a joint detection for each of the groups. Two receiver structures are considered in this paper; namely, group zero forcing (GZF) and group successive interference cancellation (GSIC). We assess the diversity-multiplexing tradeoff function of each of these receivers over a richly scattered Rayleigh fading channel. Three rate-allocation algorithms will be considered here; namely, equal rate, group-size proportional rate, and optimal-rate allocation. An explicit expression of the system tradeoff will be derived for both receivers with these three rate allocations. The obtained results will first be optimized over all possible group partitions for a given number of groups. Next, the number of groups will be varied to further optimize the system-tradeoff performance. An overall optimum tradeoff for a general MIMO system with group detection will then be obtained. Numerical results will indicate that optimum performance can be approached with very-low-complexity schemes for a wide range of data rates. It will be also demonstrated that group detection bridges the gap between the traditional decorrelator and the optimal receiver tradeoff performances.
Abstract 2585: Bioactive compounds or metabolites from black raspberries modulate T lymphocyte function, myeloid cell differentiation and Jak/STATsignaling (2014)

Abstract Bioactive phyotochemicals from natural products, such as black raspberries have direct anti-cancer properties on malignant cells in culture and in xenograft models. In addition, black raspberry components inhibit cancer progression in more complex rodent carcinogenesis models. Although mechanistic targets for black raspberry phytochemicals in cancer cells are beginning to emerge, the potential role in modulating host immune processes impacting cancer have not been systematically examined. We hypothesized that black raspberries contain compounds capable of eliciting potent immunomodulatory properties that impact cellular mediators relevant to chronic inflammation and tumor progression. In the present report, we studied both an ethanol extract from black raspberries (BRB-E) containing a diverse mixture of phytochemicals and two abundant phytochemical metabolites of black raspberries produced upon ingestion (Cyanidin-3-Rutinoside, C3R; Quercitin-3-rutinoside, Q3R). BRB-E inhibited proliferation of CD3/CD28 activated human CD4+ and CD8+ T lymphocytes. BRB-E also limited the viability of CD3+ T cells cultured in IL-2, and were potent inhibitors of IL-2-induced STAT5 phosphorylation. Conversely, BRB-E significantly enhanced the monokine-induced by gamma (MIG)-mediated chemotaxis of CD8+ T lymphocytes in transwell assays. This enhanced chemotaxis was associated with upregulated expression of CXCR3 on T lymphocytes. BRB-E also inhibited the in vitro expansion of myeloid-derived suppressor cells (MDSC). Consistent with the reduction in MDSC, pre-treatment of immune cells with BRB E attenuated IL-6-mediated signal transducer and activator of transcription-3 (STAT3) phosphorylation. Finally, the C3R and Q3R metabolites were also found to be immunomodulatory, as C3R inhibited proliferation of CD3/CD28 activated T lymphocytes and STAT5 phosphorylation, while Q3R inhibited MDSC expansion and STAT3 signaling but not STAT5. Together these data indicate that black raspberries or their physiologically-relevant metabolites contain phytochemicals that affect immune processes relevant to carcinogenesis. Furthermore, specific components and their metabolites may be a source of lead compounds for drug development that exhibit targeted immunological outcomes or inhibition of specific STAT-regulated signaling pathways.

Tuning the Gate Opening Pressure of Metal–Organic Frameworks (MOFs) for the Selective Separation of Hydrocarbons (2012)

Separation of hydrocarbons is one of the most energy demanding processes. The need to develop materials for the selective adsorption of hydrocarbons, under reasonable conditions, is therefore of paramount importance. This work unveils unexpected hydrocarbon selectivity in a flexible Metal-Organic Framework (MOF), based on differences in their gate opening pressure. We show selectivity dependence on both chain length and specific framework-gas interaction. By combining Raman spectroscopy and theoretical van der Waals Density Functional (vdW-DF) calculations, the separation mechanisms governing this unexpected gate-opening behavior are revealed.

This presentation will provide an update of the technological advancements since this initial work from 2004. This recent work includes the development of functional prototypes that are much smaller than previous prototypes using a design architecture that is easily scalable. Performance has been significantly improved by increasing the optical field of views and video refresh rate. Real-time image processing capabilities have been developed to enhance the image quality and functionality over a wide range of operating conditions. Actual images of various objects will be presented.
Laser diode cavity ring-down spectroscopy using acousto-optic modulator stabilization (1997)

By using an acousto-optic modulator, we have stabilized a free-running continuous wave (CW) laser diode in the presence of strong reflections from a high finesse Fabry–Perot resonator. The laser diode linewidth can be stabilized from several MHz, for high resolution spectroscopy of species at low pressures, to several hundred MHz, for lower resolution spectroscopy of species at atmospheric pressures. We demonstrated CW cavity ring-down spectroscopy of water vapor at both 1 atm and 5 Torr. We achieved ring-down repetition rates of 10–50 kHz, and a noise level of 2×10−8 cm−1.

Microscopic and spectroscopic characterization of interfaces and dielectric layers for OFET devices (2008)

Abstract The functionality of organic devices is strongly influenced by their interfaces. We report on new microscopic methods for interface characterization of organic devices in operation mode. With photoemission electron microscopy (PEEM), a direct mapping of charge carrier density is possible. Microscopy in the scanning Kelvin force mode (SKPM) gives information about the local surface potential. In addition to lateral information, depth profiling of interface chemistry is important. As an example, we present a study of the electrode/dielectric layer interface, performed using photoelectron spectroscopy. This interface is of technological relevance for organic memories, based on organic field effect transistors (OFETs). The dielectric part is made of ferroelectric polymers like poly(vinylidene fluoride‐trifluoroethylene) (P(VDF‐TrFE)). We compare aluminium/P(VDF‐TrFE) and PEDOT:PSS/P(VDF‐TrFE) interfaces (PEDOT:PSS is the conductive polymer poly(3,4‐ethylenedioxythiophene):polystyrenesulphonate). Finally we present memory elements consisting of metal ferroelectric insulator semiconductor (MFIS) and OFET structures. (© 2008 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
Microstructure and Mechanical Properties of TiNiFe Shape Memory Alloys with Different Compositions (2016)

The microstructure and mechanical properties of TiNiFe alloys with different compositions was investigated by tensile test, X-ray diffraction, EBSD, SEM, and TEM. The results indicated that tensile strength rapidly increased with increasing Ni content. In addition, Ti 2 (Ni,Fe) particles were observed in the TiNiFe alloys, which affected the mechanical properties. Increasing the content of Ni had little influence on the grain size of TiNiFe alloys. With the replacement of Ni by Fe, the lattice constant of TiNiFe alloys decreased as the Ni content increased.
An Asic-based System For Stripping Voltammetric Determination Of Trace Metals (2005)

The work presented here is part of an overall voltammetric design system with a silicon based disposable component for the determination of copper, cadmium, lead and zinc. Voltammetric (the measurement of current as a function of potential) methods of analysis water are attractive for determinations of trace metals. They offer a combination of simple low cost instrumentation with excellent sensitivity and detection limits, comparable to those obtainable with instruments cost orders of magnitude greater. The system consists of electrodes, an application specific integrated circuit (ASIC) and software control. There is increasing pressure on industry and regulatory bodies to monitor industrial and domestic pollution. A particular concern is the contamination of water supplies with heavy metals. The aim of this work is to develop a method of heavy metal analysis using a device that can be manufactured by means that are compatible with microelectronics processes giving a low cost solution to trace metal analyses for water quality applications.

Synthesis of Valnemulin Hydrochloride (2010)

Valnemulin hydrochloride was synthesized by reaction from D-valine with methyl acetoacetate, anhydridisation with isobutyl chloroformate, amidation with [(2-amino-1,1-dimethylethyl)thio]acetic acid (3aS,4R,5S,6S,8R,9R,9aR,10R)-6-ethenyldecahydro-5-hydroxy-4,6,9,10-tetramethyl-1-oxo-3a,9-propano-3aH-cyclopentacycloocten-8-yl ester(5) followed by deprotection with hydrochloric acid. Compound 5 was prepared from pleuromutilin by tosylation and substitution with 1-amino-2-methylpropane-2-thiol hydrochloride. The overall yield was about 64%(based on pleuromutilin).
Antioxidant properties of marine macroalgae (2014)

Antioxidants could attenuate the oxidative damage through direct scavenging effects on free radicals and/or boosting the body's natural cellular defenses. This chapter discusses recent advances in the search for potential antioxidant ingredients from marine macroalgae, with special emphasis on the antioxidant properties of algal polyphenols and sulfated polysaccharides. Marine macroalgae are a rich source of polyphenols and sterols. A series of polyphenolic compounds such as catechins, flavonols, and flavonol glycosides have been identified from methanol extracts of several red and brown algae. Direct seaweed-derived antioxidants into food products or supplements for human consumption, the extraction and purification techniques are of prime importance. The impact of processing conditions on the stability and bioavailability of seaweed derived antioxidants needs to be investigated. The potential interaction or complexation of these compounds with other food ingredients (proteins, carbohydrates, and lipids) as well as their influence on antioxidant effects should also be addressed.

Integrated and mutated forms of Merkel cell polyomavirus in non-small cell lung cancer (2013)

Sir,

We appreciate the insightful comments provided by Shuda et al (2013) regarding our recent report ‘Detection of Merkel cell polyomavirus with a tumour-specific signature in non-small cell lung cancer' (Hashida et al, 2013).

According to GenBank data, two amino-acid sequences of the non-tumour-derived Merkel cell polyomavirus (MCPyV) strain Appendix206 (GenBank accession numbers {type:entrez-nucleotide,attrs:{text:JN038578,term_id:354683949,term_text:JN038578}}JN038578 and {type:entrez-nucleotide,attrs:{text:JN038579,term_id:354683952,term_text:JN038579}}JN038579) are deposited under the same title ‘Merkel cell polyomavirus isolate Appendix206 large T antigen gene, partial cds; and small T antigen gene, complete cds'. In our study (Hashida et al, 2013), we compared the sequences of Appendix206 ({type:entrez-nucleotide,attrs:{text:JN038578,term_id:354683949,term_text:JN038578}}JN038578) with the sequences of viral strains isolated from our four MCPyV-positive non-small cell lung cancers (NSCLCs) (SCC15, AC35, AC39 and AC43). As Shuda et al (2013) noted, the two sequences deposited in GenBank with the same descriptions of ‘definition', ‘source of organism' and ‘features' are confusing and indistinguishable.

Our MCPyV strains had the wild-type retinoblastoma tumour-suppressor protein-binding motif. The more important results in our paper are the detection of integrated and large T (LT) gene mutated forms of MCPyV in one squamous cell carcinoma (SCC15) and one adenocarcinoma (AC43). The tumour AC43 possessed both an integrated MCPyV and frameshift mutations that truncate the LT gene to eliminate its helicase activity. The tumour SCC15 appears to have wild-type MCPyV, as the full-length LT gene sequence was determined by direct sequencing of polymerase chain reaction products, as shown in Figure 4 in our previous report (Hashida et al, 2013). However, we demonstrated that the AC43 tumour also carried integrated virus with the virus–host junction located in the LT gene at nucleotide position 2738, interrupting the helicase domain (nucleotide positions 1947–3017). These findings suggest the coexistence in the tumour of an integrated/truncated form and an episomal form of MCPyV. This phenomenon was also reported in MCPyV-positive Merkel cell carcinoma (Laude et al, 2010; Martel-Jantin et al, 2012).

Thus, we found two cases of NSCLC infected with MCPyV possessing a tumour-specific feature, which to our knowledge has not been reported in any specific malignancy other than Merkel cell carcinoma and chronic lymphocytic leukaemia. As Shuda et al (2013) commented, a follow-up study of these MCPyV-positive NSCLC cases is well worth doing.

Primary parasitoids of aphids (Hemiptera Aphididae) reported in New Zealand (2007)

There is growing interest in utilising the cues that small insects use to find their hosts in applied pest management. However, the underlying behaviours involved in small insect host-finding are still not well understood. The primary focus of an ongoing PhD project is to investigate the fundamental host-finding behaviour of small pest insects using thrips as model organisms. It is hypothesised that colours and odours are used by flower-dwelling thrips as cues for detection of, and orientation to, hosts. Two species, Frankliniella occidentalis (western flower thrips (WFT)) and Thrips tabaci (onion thrips (OT)), will be studied in this project. Both are cosmopolitan polyphagous pests of many food and ornamental crops. Yellow, white and blue traps have all been shown to attract WFT and OT, and it has been demonstrated that these thrips respond to the odour methyl isonicotinate. This project links what is known about thrips' response to colour and odour cues with observed behavioural responses in the field from several novel experimental set-ups. These observations will be used to determine the role of colour and odour cues during host-finding and develop a model of thrips' host-finding behaviour.
