High-Q continuously tunable zipping varactors with large tuning range (2008)

The design, simulation and fabrication of high-Q zipping MEMS varactors have been presented. A novel, stable zipping design allows continuous tuning as well as a large tuning range. High quality factors can be obtained using gold electrodes in order to minimise series resistance. A minimum Q of 94 at 1 GHz has been obtained from HFSS simulations in a varactor with SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> dielectric, and this is much higher than semiconductor varactor Q values which are typically in the low tens [1, 5]. By incorporating a high-permittivity dielectric in the varactor, the tuning range can be greatly increased and at the same time, the device size can be reduced. This is a particularly important advantage for applications where size reductions or maintaining the same system size while increasing functionality is required (e.g. mobile handsets). A fabrication process has been developed, including pre-stressed layers to provide the initial curvature, and this has been demonstrated up to and including transfer and bonding of the top electrodes from a carrier wafer. Suitable applications for the zipping varactors include tunable filters, phase shifters, oscillators and tunable matching networks for mobile antennas.
From color to appearance in the real world (2012)

X-Rite's declared ambition is to create a digital ecosystem for appearance; a daunting challenge that has many dimensions and has proven so massive that all previous attempts efforts have failed so far. After having invested three years in exploring the problem, we can now deliver the first elements of answers and the practical path to tackle this massive undertaking. We will explore the practical implications of the intermediation of two stages between color and full appearance, extended color and augmented color, and how these steps, rooted in the realities of the ecosystem they serve constitute vectors and enablers of a more effective transition. We will survey the road map implication in the design for measurement and capture instrumentations, packaging digital formats and delivery infrastructure as well as rendering and display devices that will enable true value creation built on appearance attributes.
Righting the Wrong of Woytus: A Proposal for Adoption of a Rule in Missouri Creating a New Category of Depositions Which May Be Used for Discovery Purposes Only (1991)

In State ex rel.Woytus v. Ryan, 1 the Missouri Supreme Court ruled that plaintiffs in personal injury cases may not be compelled to execute authorizations granting defense counsel permission to conduct ex parte interviews of the plaintiff's treating physicians.In so ruling, the court expressed a desire to strike a balance between the interest, of personal injury plaintiffs in preserving the physician/patient privilege and the interest of personal injury defendants in obtaining full and fair disclosure of relevant information through discovery.A closer look, however, at the practical effects of the court's decision discloses that the ruling puts defense counsel at a serious disadvantage in preparing personal injury cases for trial.A new rule permitting depositions which may be used for discovery purposes only is needed to ameliorate the harsh effect of the decision.

EM∩IM: software for relating ion mobility mass spectrometry and electron microscopy data (2015)

We present EM∩IM, software that allows the calculation of collision cross-sections from electron density maps obtained for example by means of transmission electron microscopy. This allows the assessment of structures other than those described by atomic coordinates with ion mobility mass spectrometry data, and provides a new means for contouring and validating electron density maps. EM∩IM thereby facilitates the use of data obtained in the gas phase within structural biology studies employing diverse experimental methodologies.
Synthesis and Characterization of Unsymmetrical Double-Decker Siloxane (Basket Cage) (2019)

The one-pot synthesis of an unsymmetrical double-decker siloxane with a novel structure via the reaction of double-decker tetrasodiumsilanolate with 1 equiv. of dichlorotetraphenyldisiloxane in the presence of an acid is reported herein for the first time. The target compound bearing all phenyl substituents on the unsymmetrical siloxane structure was successfully obtained, as confirmed by <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, <sup>29</sup>Si-NMR, IR, MALDI-TOF, and X-ray crystallography analyses. Additionally, the thermal properties of the product were evaluated by TG/DTA and compared with those of other siloxane cage compounds.
Latitudinal profiles of stratospheric water vapor (1975)

Water vapor burden and in situ mixing ratios above and at high altitude flight levels were inferred from observations in the rotational water vapor spectral band (19.0–35.0 µm). Flight levels ranged from 15.3 to 20.0 km during 12 meridional traverses of a W‐B57‐F jet. The method of radiance observation, while radiometric, involved emission observations rather than absorption spectra analyses employed by McKinnon and Morewood [1971]. The flights made during September, October, November 1973 and January 1974 provide profiles of lower stratospheric water vapor by overlapping tracks from 50°S latitude to 75°N latitude. The objective of the research is to describe the method of recovery of the water vapor burden and in situ mixing ratio by inference from infrared emission observations and to present the results as a latitudinal profile.
Gestational diabetes mellitus and cardio-metabolic risk factors in women and children at 3 years postpartum (2022)

Exposure to GDM is associated with elevated serum triglycerides in women at 3 years postpartum but other cardiometabolic outcomes in women and children appear to be mediated by early pregnancy BMI and SEI.
IC‐P‐151: Baseline Discrepancies in MRI Patch‐Based Appearance Predictive of Future Decline in Cognitively Healthy ADNI Participants (2016)

We proposed a novel MRI segmentation technique (NeuroImage:Clinical 1(1):141-152, 2012) able to grade a new image according to information from a pre-labeled set of training images. Using the concept of “patches”, or small local voxel neighbourhoods, the algorithm matches such patches within a structure of interest to similar neighbourhoods in the training images. Each patch is tagged with information known a priori from the selected training images, thus achieving both segmentation and grading simultaneously. In this context, the grade (“SNIPE” score) expresses the similarity to probable AD. While the technique has been applied (cf. referenced manuscript) for the aid to diagnostic between probable AD and cognitively healthy participants (CTRL; accuracy 89%), aid to prognostic of MCI subjects progressing to probable AD (accuracy 71%), we wanted to test the hypothesis that the SNIPE score would prove sufficiently sensitive to early brain changes associated with AD in asymptomatic individuals. We tested SNIPE on baseline T1w MRIs of ADNI-1 CTRL with long-term follow-up. We used the same training set as the reference above. The test set consisted in 222 cognitively healthy participants from ADNI-1 (107 females; age (mean ±SD): 76.0±5.0), followed on average 5.2 ±2.4 years (range: 0.5-8.5). During follow-up, 38 progressed to MCI (time to conversion 4.7 ±1.9 years) and 13 to probable AD (mean time to conversion 5.4 years ±1.8). The SNIPE score was calculated on both left and right hippocampi (rHPC, lHPC), as defined by the Pruessner protocol (Cereb. Cortex2000). We calculated regression models for the rHPC and lHPC, using age, sex, structure volume, and progression group as predictors. Qualitative differences between the trajectory of SNIPE scores can be appreciated between all three groups (Figure 1). Regression parameters revealed that for the rHPC both NC-to-MCI (p = .003) and NC-to-AD (p = .003) progression groups clearly differed from the non-progression group, while this effect was less pronounced for the lHPC (p = .147; p= .034).
Mobile phone-to-phone personal context sharing (2009)

Sharing personal context information using mobile phone is receiving considerable attentions in ubiquitous computing applications. The most common architecture for sharing personal context information via mobile phone uses centralized server. Such server-based architecture, however, cannot avoid waste of mobile phone's limited resources for sharing personal context information. Additionally, dynamic privacy control of the shared context information according to user's various situations is very difficult in the server-based architecture. The increased computation power of mobile phone enables us to create system architecture that can share personal context information between two mobile phones directly. In this paper, we describe design of system architecture for lightweight interactive mobile phone-to-phone personal context sharing system that uses SMS (Short Message Services) as a basic communication method, and introduce application prototypes that are developed based on the proposed architecture. Compared to centralized server-based architecture, the proposed one can minimize waste of limited mobile phone resources and maximizes dynamic privacy control in sharing personal context information.
Differential GH-releasing hormone regulation of GHRH receptor mRNA expression in the rat pituitary (2001)

To understand the capacity of growth hormone-releasing hormone (GHRH) to regulate expression of the GHRH receptor, we studied the effects of GHRH on GHRH receptor mRNA expression in immature and adult rats by use of pituitary cell culture and immunoneutralization approaches. Pituitary cell cultures from neonatal (2-day-old) and adult (70-day-old) rats were treated with GHRH for 4, 24, or 72 h. The effect of GHRH on GHRH receptor mRNA expression depended on the duration of GHRH exposure in both age groups; short-term (4 h) GHRH treatment significantly reduced GHRH receptor mRNA expression (P < 0.05), whereas intermediate treatment (24 h) restored GHRH receptor mRNA to basal levels, and long-term treatment (72 h) stimulated GHRH receptor mRNA expression (P < 0.02). The long-term stimulatory effect of GHRH on GHRH receptor mRNA expression required the presence of serum in the culture medium, and, in the absence of serum, the stimulatory effect was completely abolished. Moreover, the capacity of the pituitary to increase GHRH receptor mRNA expression in response to 72-h GHRH treatment was age dependent, with neonatal pituitaries exhibiting a much greater stimulatory effect than adult pituitaries (P < 0.025). Immunoneutralization of endogenous GHRH significantly reduced GHRH receptor mRNA expression in neonatal (P < 0.004), juvenile (P < 0.003), and mature (P < 0.004) pituitaries compared with age-matched controls. Taken together, these results indicate that GHRH is a potent regulator of GHRH receptor gene expression in immature and mature pituitaries; however, the nature and direction of GHRH regulation of its receptor depend significantly on several variables, including the duration of GHRH exposure, the presence of permissive components in serum, and the developmental stage of the pituitary.
S1104-1-4 Traction characteristics of functionalized polyalkylmethacrylates under EHL contacts (2009)

Traction behavior of the oils containing functionalized polyalkylmethacrylates (PAMAs) was determined with a sapphire disk-on-steel roller tester. Experiments were conducted under the slide/roll ratio of 50%, a mean rolling speed between 0.004 and 1 m/s, and a temperature of 40C. In the traction-speed curves the measurements for all the polymer solutions fell on the base oil line in the high speeds, while those in the low speeds were lower values than the base oil. The traction at the film parameter below 4 depended on the composition of polymer solution. It was inferred that such a traction behavior could be explained by the existence of thin film lubrication
Higher Order Cross-Correlation Functions from Galaxy-Galaxy-Galaxy Lensing (2004)

Galaxy-galaxy lensing (GGL) measures the 2-point cross-correlation between galaxies and mass in the universe. In this work we seek to generalise this effect by considering the third-order correlations between galaxies and mass: galaxy-galaxy-galaxy lensing. We introduce the higher-order cross-correlation functions and discuss their physical interpretation in terms of the halo model. We then demonstrate that measuring the lensing shear of background galaxies about foreground galaxy pairs, which we term galaxy-galaxy-galaxy lensing, provides a measure of the third-order cross functions. We note that current surveys in which detections of the cosmic shear 3-point correlation function have been reported should also be able to detect galaxy-galaxy-galaxy lensing. Indeed, we suggest that this effect may already have been detected in recent studies of GGL.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
Coculture with Late, but Not Early, Human Endothelial Progenitor Cells Up Regulates IL-1βExpression in THP-1 Monocytic Cells in a Paracrine Manner (2013)

Endothelial progenitor cells (EPCs) have been used in clinical trials to treat ischemic heart disease. Monocyte infiltration plays an important role in inflammation, angiogenesis, and tissue repair during tissue ischemia. It is important to understand the interactions between EPCs and monocytes. In this study, a human EPC/THP-1 monocytic cell coculture system was used to examine EPC effect on IL-1 α , IL-1 β , and TNF- α expression in THP-1 cells. Late, but not early, EPCs upregulated IL-1 β expression at both mRNA and protein levels. In contrast, neither early nor late EPCs affected IL-1 α or TNF- α expression. Coculture with human umbilical vein endothelial cells did not alter IL-1 β expression. It has been shown that activation of integrin β 2 in human neutrophils augments IL-1 β synthesis; however integrin β 2 was not involved in IL-1 β expression in THP-1 cells. Addition of late EPC conditioned medium to THP-1 cell culture led to a modest increase of IL-1 β mRNA levels, indicating that late EPCs upregulate IL-1 β expression partly through a paracrine pathway. IL-1 β , an important inflammation mediator, has been shown to promote EPC function. Our data therefore suggest that late EPCs can exert self-enhancement effects by interacting with monocytes and that EPCs might modulate inflammatory reactions by regulating IL-1 β expression in monocytes.
Assessment of the CRIP (Controlled Retracting Injection Point) process for underground coal gasification: The Rocky Mountain I test (1988)

Results of the recently completed Rocky Mountain I (RMI) underground coal gasification (UCG) field test have shown that the Controlled Retracting Injection Point (CRIP) process for UCG is capable of producing consistently high quality gas from a single injection well for an extended period of time. The RMI CRIP module was in operation for 93 days and gasified over 10,000 tonnes (11,023 tons) of coal, with an average dry product heating value of 253 kJ/mol (287 Btu/scf). The CRIP process, which utilizes a horizontally drilled injection borehole, has the advantage over vertical well process techniques in that it maintains oxidant injection low in the coal seam for optimal resource recovery, and provides a method for reignition of the coal in a different location when gas quality declines as the maturing reactor begins to interact with inert overburden. This report discusses the results of the RMI CRIP module, compares its performance with the simultaneously operated Extended Linked Well (ELW) module, and explains the behavior of the CRIP reactors with the aid of a model developed for describing UCG reactor dynamics for cases in which oxidant injection remains low in the coal. It is shown that both in terms of fundamental understandingmore » and practical application, the CRIP process for UCG in subbituminous and lower ranking coals has reached a level where the remaining technical uncertainties and risk to commercial development have been largely reduced. 6 refs., 8 figs., 4 tabs.« less
Xanthohumol, a prenylated chalcone derived from hops, inhibits proliferation, migration and interleukin-8 expression of hepatocellular carcinoma cells (2009)

Xanthohumol, the major prenylated chalcone found in hops, is well known to exert anti-cancer effects, but information regarding the impact on hepatocellular carcinoma (HCC) cells and potential adverse effects on non-tumorous hepatocytes is limited. Here, we show that xanthohumol at a concentration of 25 microM induced apoptosis in two HCC cell lines (HepG2 and Huh7). Furthermore, xanthohumol repressed proliferation and migration, as well as TNF induced NF-kappaB activity and interleukin-8 expression in both cell lines at even lower concentrations. In contrast, xanthohumol concentrations up to 100 microM did not affect viability of primary human hepatocytes in vitro. In summary, our data showed that xanthohumol can ameliorate different pro-tumorigenic mechanisms known to promote HCC progression, indicating its potential as promising therapeutic agent that selectively affects cancer cells.

RadTrac: A System for Detecting, Localizing, and Tracking Radioactive Sources in Real Time (2009)

Within the homeland security and emergency response communities, there is a need for a low-profile system to detect and locate radioactive sources. RadTrac has been developed at Argonne National Laboratory as an integrated system for the detection, localization, identification, and tracking of radioactive sources in real time. The system is based on a network of radiation detectors and advanced signal-processing algorithms. Features include video surveillance, automated tracking, easy setup, and logging of all data and images.This paper describes the advanced algorithms that were developed and implemented for source detection, localization, and tracking in real time. In the physio-spatial integration approach to source localization, counts from multiple detectors are processed according to the underlying physics linking these counts to obtain the probability that a source is present at any point in space. This information is depicted in a probability density function map. This type of depiction allows the results to be presented in a simple, easy-to-understand manner. It also allows for many different complicated factors to be accounted for in a single image as each factor is computed as a probability density in space. These factors include spatial limitations, variable shielding, directional detectors, moving detectors, and different detector sizes and orientations. The utility and versatility of this approach is described in further detail. Advanced signal-processing algorithms have also been incorporated to improve real-time tracking and to increase signal-to-noise ratios including temporal linking and energy binning.Measurements aimed at demonstrating the sensitivity improvements through the use of advanced signal-processing techniques were performed and are presented. Results of tracking weak sources (<100 μCi 137Cs) using four fixed-position detectors are presented.
A log-domain implementation of the Mihalas-Niebur neuron model (2010)

We present an electronic neuron that uses first-order log-domain low-pass filters to implement the Mihalas-Niebur model. The neuron consists of a leaky-integrate-and-fire core and building blocks to implement an adaptive threshold and spike induced currents. Simulation results show that this modular neuron can emulate different spiking behaviours observed in biological neurons.
Regulation of 5-aminolevulinate synthase mRNA in different rat tissues. (1988)

cDNA clones for rat liver 5-aminolevulinate synthase have been isolated and used to examine mRNA levels in different rat tissues. Northern hybridization analysis of total RNA from various rat tissues showed the presence of a single 5-aminolevulinate synthase mRNA species of estimated length 2.3 kilobases. Primer extension and RNase mapping studies indicated that the mRNA is identical in all tissues. Highest basal levels were seen in liver and heart. Administration of hemin to rats reduced the basal level of this mRNA only in liver but the heme precursor, 5-aminolevulinate (or its methyl ester), repressed the basal levels in liver, kidney, heart, testis, and brain. The drug 2-allyl-2-isopropylacetamide increased the mRNA level in liver and kidney only while human chorionic gonadotropin hormone elevated the level in testis. Administration of the heme precursor 5-aminolevulinate prevented these inductions. Nuclear transcriptional run-off experiments in liver cell nuclei showed that 2-allyl-2-isopropylacetamide and 5-aminolevulinate exert their effect by altering the rate of transcription of the 5-aminolevulinate synthase gene. The results indicate that a single 5-aminolevulinate synthase mRNA is expressed in all tissues and that its transcription is negatively regulated by heme.

Decomposing the effects of ocean warming on chlorophyll a concentrations into physically and biologically driven contributions (2013)

Recently compiled observational data suggest a substantial decline in the global median chlorophyll a concentration over the 20th century, a trend that appears to be linked to ocean warming. Several modelling studies have considered changes in the ocean's physical structure as a possible cause, while experimental work supports a biological mechanism, namely an observed increase in zooplankton grazing rate that outpaces phytoplankton production at higher temperatures. Here, we present transient simulations derived from a coupled ocean general circulation and carbon cycle model forced by atmospheric fields under unabated anthropogenic global warming (IPCC SRES A1FI scenario). The simulations account for both physical and biological mechanisms, and can reproduce about one quarter of the observed chlorophyll a decline during the 20th century, when using realistically parameterized temperature sensitivity of zooplankton metabolism (Q10 between 2 and 4) and phytoplankton growth (Q10 ~ 1.9). Therefore, we have employed and re-calibrated the standard ecosystem model which assumes a lower temperature sensitivity of zooplankton grazing (Q10 = 1.1049) by re-scaling phytoplankton growth rates and zooplankton grazing rates. Our model projects a global chlorophyll a decline of >50% by the end of the 21st century. While phytoplankton abundance and chlorophyll a experience pronounced negative effects, primary production and zooplankton concentrations are less sensitive to ocean warming. Although changes in physical structure play an important role, much of the simulated change in chlorophyll a and productivity is related to the uneven temperature sensitivity of the marine ecosystem.
