Synthesis of Pendant Radical- and Ion-Containing Block Copolymers via Ring-Opening Metathesis Polymerization for Organic Resistive Memory (2014)

Ring-opening metathesis polymerization (ROMP) using Grubbs third-generation catalyst directly yielded a norbornene-based polymer bearing robust redox-active radicals without any protection. Successive addition of imidazolium-containing norbornene in a one-pot reaction during ROMP produced pendant radical- and ion-containing block copolymers. The diode-structured thin-film devices fabricated with the obtained block polymers that had morphologies of spheres, lamellae, and inverse spheres exhibited conductive switching (write-once read-many-times, WORM) under a bias voltage, which revealed the dominant effect of the location of radicals and ions in the microphase-segregated domains on memory characteristics.
Responsiveness of genes to manipulation of transcription factors in ES cells is associated with histone modifications and tissue specificity (2011)

We thus propose the responsiveness of expression to perturbations as a new way to define the dynamic status of genes, which brings new insights into mechanisms of regulation of gene expression and tissue specificity.

Delivering temporary flood defence deployment plans: lessons learned from case studies in the UK (2018)

Temporary flood barriers can be used to create short-term, artificial walls blocking water flow across a floodplain as an alternative to permanent heavy-engineering solutions. However, to be successful, there needs to be an effective plan for the deployment of temporary flood defences. The authors of this paper highlight the lessons learned and knowledge gained through producing site-specific temporary flood defence deployment plans at Torksey Lock and St Neots in the UK. A deployment plan should operate at operational, strategic and tactical levels, with limitations at each level considered. It should also aim to resolve the risks associated with previous experiences of operational failure of temporary barriers. Limitations nevertheless remain, including awareness of and response to a structural failure. Testing of deployment plans is beneficial to flood risk engineers, emergency planning practitioners and the wider community.
Abstract B51: Management of ascites via the alfa-pump closed system in platinum-resistant-ovarian-cancer (PROC): A model of sequential non-invasive tumor-cell sampling through the urinary bladder (2013)

Abstract Background: Malignant ascites in PROC is a therapeutic dilemma. The Sequana-Medical alfapump-System (AP), a remotely controlled device connecting the patients'peritoneal cavity to their urinary bladder, has been evaluated for ascites in liver cirrhosis, but not as yet for malignant ascites. Methods: We implanted the AP in the peritoneal cavity of two heavily pretreated PROC-patients (67y and 70y) who required repetitive ascites drainages monthly. We cross correlated the electronic download of recorded volume pumped (intraperitoneally→bladder) with weekly ultrasound, monthly cystoscopies and QoL-evaluation. Early morning urine for evaluation of cytology and tumor-cell molecular analysis was collected weekly. Results: The implantation was under general anesthesia in a 60- and 35-minute procedure. The pump, draining 350ml – 500ml ascites/day successfully drained the ascites to dryness after 3 days (1stpatient) and 8 days (2ndpatient). The patients did not report pollakiuria or dysuria, merely an increased micturition volume. The 1st patient died of disease progression 2 months later; the 2nd patient we noticed a gradual amelioration of peripheral edemas and overall performance-status within 3 weeks after insertion and was able to commence weekly chemotherapy with paclitaxel. Histopathological analysis of the urine revealed rich malignant cell content; this was used to create FFPE-cell-blocks for molecular- pathological profiling with sequential Caris-Target-Now-analysis and full exome-sequencing. QoL as measured by the EORTC QlQ-C30 and EORTC QLQ-OV28 showed high interindividual differences and only minimal influence by the pump. Conclusion: This innovative approach addresses an area of unmet need for the control of malignant ascites and provides a non-invasive method of collecting tumor tissue for continuous molecular tumor characterization. A EUTROC-multicenter randomized-trial (AMAZE) is planned for evaluation of clinical and translational implications in PROC.

Graft Transmission of RNA Silencing to Non-Transgenic Scions for Conferring Virus Resistance in Tobacco (2013)

RNA silencing is a mechanism of gene regulation by sequence specific RNA degradation and is involved in controlling endogenous gene expression and defense against invasive nucleic acids such as viruses. RNA silencing has been proven to be transmitted between scions and rootstocks through grafting, mostly using transgenic plants. It has been reported that RNA silencing of tobacco endogenous genes, NtTOM1 and NtTOM3, that are required for tobamovirus multiplication, resulted in high resistance against several tobamoviruses. In the present study, we examined the graft transmission of RNA silencing for conferring virus resistance to non-transgenic scions of the same and different Nicotiana species grafted onto rootstocks in which both NtTOM1 and NtTOM3 were silenced. Non-transgenic Nicotiana tabacum (cvs. Samsun and Xanthi nc) and N. benthamiana were used as scions for grafting onto the rootstocks silenced with both genes. Short interfering RNA (siRNA) of NtTOM1 and NtTOM3 was detected in both the scions and the rootstocks eight weeks after grafting. The leaves were detached from the scions and inoculated with several tobamoviruses. The virus accumulation was tested by ELISA and northern blot analysis. The viruses were detected in grafted scions at extremely low levels, showing that virus resistance was conferred. These results suggest that RNA silencing was induced in and virus resistance was conferred to the non-transgenic scions by grafting onto silenced rootstocks. The effect of low temperature on siRNA accumulation and virus resistance was not significantly observed in the scions.

Differentiation of tricuspid regurgitation from constrictive pericarditis: novel criteria for diagnosis in the cardiac catheterisation laboratory (2009)

The haemodynamic findings at cardiac catheterisation in patients with severe, symptomatic tricuspid regurgitation are similar to those of constrictive pericarditis. Careful analysis of the relationship of the LV and RV diastolic pressures during respiration can help differentiate the two entities.
Contrast-Variation Time-Resolved Small-Angle Neutron Scattering Analysis of Oil-Exchange Kinetics Between Oil-in-Water Emulsions Stabilized by Anionic Surfactants (2019)

Contrast-variation time-resolved small-angle neutron scattering (CV-SANS) was used to examine oil-exchange kinetics between identical mixtures of hydrogenated/deuterated hexadecane emulsion systems. Oil-exchange rates were estimated by transforming recorded scattering profiles to a relaxation function and by fitting to exponential decay models. We find that the oil-exchange process was accelerated when the droplets were stabilized by anionic surfactants even at concentrations well below the surfactant critical micelle concentration. Moreover, the exchange rate was not significantly accelerated when surfactant micelles were present. This suggests that micellar-mediated transport mechanisms do not play the dominant role in these systems. Screening electrostatic repulsion by increasing the ionic strength of the medium also had a negligible effect on oil-exchange kinetics. In contrast, the use of oils with shorter alkane chain lengths (e.g., dodecane), having a higher solubility in water, significantly accelerated rates of oil transport between droplets. Oil-transport rates for hexadecane were also found to increase with temperature and to follow Arrhenius behavior. These results were rationalized as an increase in the droplet-collision frequency due to Brownian motion that results in direct oil transport without irreversible coalescence. Thus, primary mechanisms for oil exchange in insoluble anionic surfactant-stabilized emulsion systems are hypothesized to be through direct emulsion contact, reversible coalescence, and/or direct oil permeation through thin liquid films. CV-SANS is also demonstrated as a powerful technique for the study of transport kinetics in all kinds of emulsion systems.
&lt;title&gt;Parameters influencing the behavior of a new friction damper device&lt;/title&gt; (2000)

This work presents a study on the parameters that govern the performance of a new Friction Damper Device (FDD) The device was designed to dissipate seismic input energy and protect buildings from structural and nonstructural damage during moderate and severe earthquakes. The device consists of 3 steel plates that rotate against each other in different directions, and in between these plates, friction pad material discs are inserted. The damper is attached to structures by using inverted Chevron bracing system and in this work pre- stress bars were used as bracing members. The clamping force in the pretensioned bolt controls the frictional moment at the onset of sliding. The device has been tested intensively in order to verify its performance. The experimental program included two phases: (1) Testing the damper alone with Instron machine, examining three different friction-pad materials. (2) Testing a scaled steel frame model with inserted damper device. In both phases the following parameters were tested: forcing frequencies, normal forces, displacement amplitudes, pre-stressing forces and degradation under long-term cyclic excitation. The tests proved that the damper performance is: (1) Independent of forcing frequency within the range of 2 - 7 Hz; (2) Linearly dependent on displacement amplitudes; (3) Linearly dependent on normal forces; (4) Very stable over many cycles. The new device is characterized by the use of special friction pad material, which has been tested for up to 400 and 500 cycles without showing degradation of friction forces more than 5%. Besides, the steel plates were not damaged or scratched so that they can be used for many times. The comparison of results obtained from the experimental and numerical models showed a good agreement. The parameters influencing the frame with FDD were identified in advance by studying the frame's response to static and dynamic loading. The numerical studies demonstrated that the overall frame response was mainly affected by the geometry of the damper, frictional sliding moment and stiffness of the added brace. The device is very easy to manufacture and implement in structures. It is a very economic device due to material availability. It can be easily replaced if it is damaged, which is extremely unlikely, or can be readjusted after use.
Self-developing photoresist using a vacuum ultraviolet F2 excimer laser exposure (1985)

An F2 excimer laser at 157 nm has been used for the first time as an exposure source for high resolution photolithography with the self-developing resist nitrocellulose. Ablative development of the nitrocellulose was observed for 157-nm energy densities greater than 0.025 J/cm2. Stencil masks fabricated using electron beam lithography were used for contact photolithography, and mask features to 200 nm were reproduced. These are the smallest features yet reproduced from a mask with an optical, self-developing resist technology.
High-Power Hall Thruster Technology Evaluated for Primary Propulsion Applications (2003)

High-power electric propulsion systems have been shown to be enabling for a number of NASA concepts, including piloted missions to Mars and Earth-orbiting solar electric power generation for terrestrial use (refs. 1 and 2). These types of missions require moderate transfer times and sizable thrust levels, resulting in an optimized propulsion system with greater specific impulse than conventional chemical systems and greater thrust than ion thruster systems. Hall thruster technology will offer a favorable combination of performance, reliability, and lifetime for such applications if input power can be scaled by more than an order of magnitude from the kilowatt level of the current state-of-the-art systems. As a result, the NASA Glenn Research Center conducted strategic technology research and development into high-power Hall thruster technology. During program year 2002, an in-house fabricated thruster, designated the NASA-457M, was experimentally evaluated at input powers up to 72 kW. These tests demonstrated the efficacy of scaling Hall thrusters to high power suitable for a range of future missions. Thrust up to nearly 3 N was measured. Discharge specific impulses ranged from 1750 to 3250 sec, with discharge efficiencies between 46 and 65 percent. This thruster is the highest power, highest thrust Hall thruster ever tested.
Scanning exposures with a MAPPER multibeam system (2011)

Currently, three MAPPER multi-electron beam lithography tools are operational. Two are located at customers, TSMC and LETI, and one is located at MAPPER. The tools at TSMC and LETI are used for process development. These tools each have 110 parallel electron beams and have demonstrated sub-30 nm half pitch resolution in chemically amplified resists. One important step towards the high volume tool is the capability to stitch the exposure of one electron beam to the next. The pre-alpha tool at MAPPER has been upgraded with an interferometer to enable exposures with a scanning stage and demonstrate first beam-to-beam stitching. A scan of 200 micrometers has been used to create a stitch area of 50 x 3 microns. The stitch error over all stitches was found to be below 25 nm. The electron beam position stability during the 10 seconds required for beam-to-beam stitching showed a contribution to the stitch error of 2.3 nm. The beam separation measurement, used to correct the static error, adds about 2.2 nm and the stage stability and linearity adds another 5 nm in the scan (interferometer) direction. In the perpendicular direction the stage instability gives the largest contribution to the stitch error (15 nm) due to the use of capacitive sensors. Overall, the electron beam stability and the beam position correction method work correctly and with sufficient accuracy for the high volume tool, 'Matrix'. The wafer stage for the Matrix system will incorporate full interferometer control to attain the needed positioning accuracy and stability.
Transversal and Lateral Exciton Energy Transfer in Grana Thylakoids of Spinach (2004)

The excitation energy transfer between photosystem (PS) II complexes was studied in isolated grana disks and thylakoids using chlorophyll a fluorescence induction measurements in the presence of DCMU under stacked and destacked conditions. Destacking of grana was achieved using a sonication protocol in a buffer without MgCl(2). The degree of stacking was controlled and quantified by atomic force microscopy and by the concomitant absorption changes. As expected from the literature, intact thylakoids showed a strong dependency of the connectivity of PSII centers, the F(m)/F(o) ratio as well as the fraction of PSIIbeta centers on the MgCl(2) concentration. In contrast, these parameters did not change in isolated grana disks. In particular, the connectivity remained constantly high irrespective of the degree of destacking. These differences were explained by the high protein density in grana disks, which hinders separation and mixing of proteins sufficiently to change energy transfer properties. Due to the occurrence of stroma lamella in intact thylakoids, intermixing of PSII and PSI is possible and allows for changes in F(m)/F(o) ratio as is the separation of LHCII from PSII, thus leading to an increase in the fraction of PSIIbeta. Even if mixing and separation of proteins are impaired in isolated grana disks, destacking should lead to a decrease in connectivity if transversal excitation energy transfer between two opposite membranes is significant. Because the connectivity is constant over all degrees of destacking employed, we conclude that the energy transfer in granas is mainly lateral.
ELID grinding characteristics of large stamping die for Wolter mirror (2009)

An ultra-precision ELID grinding of large stamping dies of Wolter mirror for X-ray telescope was presented in this paper. The large stamping dies (S55C) with confocal paraboloid and hyperboloid was ground by ELID arc-enveloped grinding. In this ELID grinding system, cast iron fiber bonded (CIFB) diamond wheels were controlled by 3-dimentional ways to scan the work-piece and generate required surfaces. Its grinding characteristics such as attainable form accuracy, surface roughness were investigated. Furthermore, some measures to improve form accuracy were discussed and verified such as truing, compensating, and on-machine measuring.
Closure to “Discussion of ‘A Paradox in Sliding Contact Problems With Friction’ ” (2006, ASME J. Appl. Mech., 73, pp. 884–886) (2006)

The purpose of our technical brief was to first demonstrate that a paradox involving slip reversal exists in a class of sliding contact problems with friction. We were then motivated by the desire to determine a mechanics formulation of these problems which is self-consistent, in which case we do not have to resort to making arguments that depend on the actual dimensions and material properties of a particular situation. We also stated “The finite strain kinematics analysis shows that the paradox disappears when the correct kinematics is used. In this case it is a reasonable engineering solution to use the infinitesimal theory with the assumption that slip is always in the original direction of sliding, because the paradox occurs only in very small regions in which the infinitesimal theory is unrealistic.”We thank the authors of the Discussion for detailing some of the issues with plasticity and rounding as related to traditional engineering materials. The statement is made in the Discussion that a radius of greater than 120 nm is necessary to avoid the paradox. While such a tiny radius may be unrealistic in many applications, it is not at all unusual in, for example, silicon MEMS devices where radii can be nearly atomically sharp as a consequence of an anisotropic etch.The plasticity analysis used in the Discussion assumed a ratio of yield stress to shear modulus of 0.003. However, in rubber and biological materials the “yield” stress can be a significantly higher fraction of the modulus. Even for traditional engineering materials, the elastodynamic problem behaves as the corresponding quasi-static problem with a reduced modulus. As pointed out in the original technical brief, this reduced modulus approaches zero as the speed of the punch approaches the Rayleigh wave speed.For the reasons outlined above we disagree with the statement that “…it is unlikely that the paradox described, though interesting, will have any bearing in a real contact.” We also reiterate that the purpose of our technical brief was to develop a mechanics formulation which is self-consistent.

Variation among sorghum genotypes for reduction in popping caused by threshing-induced kernel damage (2021)

Interest has increased in pop sorghum (Sorghum bicolor (L.) Moench) as an alternative to popcorn as an ingredient in snack foods and as a confectionary snack per se. However, studies on the effect of sorghum genotype, agronomic production and grain processing on popping quality are limited and this has hindered the development of sorghum hybrids specifically for popping. This study assessed the effects of sorghum genotypes, threshing methods, environments and their interactions on sorghum popping quality. Grain from six sorghum genotypes previously documented to have good popping quality was produced in two Texas environments and was threshed using five methods which were expected to cause varying levels of kernel damage. Popping quality, measured as popping efficiency, expansion ratio and flake size was influenced primarily by threshing method, sorghum genotype and to a lesser extent by environment and the genotype × threshing method interaction. The results herein indicate that threshing methods can significantly reduce popping quality and that sorghum genotypes differ in their inclination to threshing-induced kernel damage. Based on these results, popping quality in sorghum is optimized by selecting genotypes for high popping quality and threshing the grain using a method that inflicts minimal damage to the kernel.Abbreviations: ER, Expansion Ration; FS, Flake Size; KHI, Kernel Hardness Index; PE, Popping Efficiency; TKW, Thousand Kernel Weight; UPK, Un-popped Kernels
