An All-Digital CMOS Duty Cycle Correction Circuit with a Duty-Cycle Correction Range of 15-to-85% for Multi-Phase Applications (2005)

An all-digital CMOS duty cycle correction (DCC) circuit with a fixed rising edge was proposed to achieve the wide correction ranges of input duty cycle and PVT variations, the low standby power and the fast recovery from the standby mode for use in multi-phase clock systems. SPICE simulations showed that this DCC adjusts the output duty cycle to 50 +/- 0.7% for the wide range of input duty cycle from 15% to 85% at the input frequency of 1 GHz, within the commercial range of PVT corners. The all-digital implementation and the use of a toggle flip flop at the input stage enabled the wide correction ranges of PVT variations and input duty cycle, respectively.
Precise thickness and refractive index determination of polyimide films using attenuated total reflection (1994)

Surface plasmons generated at a silver-polyimide interface and the guided modes coupled into planar films cause dips in the reflectivity curve of a transparent dielectric-silver-polyimide-air structure. These minima in the reflectivity curve were used to measure the polyimide thickness as well as the real and imaginary parts of the polymer refractive index (extinction). Precision within 1% of the polymer coat thickness was achieved through the use of this technique over the range 0.5-10 µm. In some cases, this technique is capable of yielding a precision of ~ 10% on the imaginary part of the polymer refractive index and provides a useful method for determining the performance of a low-loss polymer waveguide. Techniques in fitting the experimental reflectivity data to obtain the optical constants are also described.
Reservoir geology of Nicholas and Liverpool Cemetery fields (lower Pennsylvanian), Stanton County, Kansas, and their significance to the regional interpretation of the Morrow Formation incised-valley-fill systems in eastern Colorado and western Kansas (2004)

Reservoirs in the lower Pennsylvanian Morrow Formation of eastern Colorado, southwestern Kansas, and northwestern Oklahoma have produced greater than 8 tcf of gas and 200 million bbl of oil. This prolific depositional system produces from reservoirs representing a range of depositional environments from updip, fluvial-dominated, incised-valley fills to deep-water basin-floor systems. The valley fills of the Morrow Formation are of particular significance because they can be mapped in great detail from subsurface control over very long distances. Facies distributions in the valleys change systematically downdip. As a result, reservoir characteristics and trapping mechanisms vary with these changes in internal valley stratigraphy.This paper focuses on the reservoir geology of Nicholas and Liverpool Cemetery fields. These fields produce gas from the extreme downdip region of an incised-valley-fill system in the lower Morrow Formation. The valley systems in this downdip region are deeper and wider and demonstrate greater marine influence than the updip regions of the valley systems farther north and into the hinterland.Compartmentalization in these downdip reservoirs differs significantly from updip valley-fill reservoirs. The reservoirs in this downdip region are more highly compartmentalized because the dominant reservoir facies in these fields is a series of bayfill delta deposits. These deposits are isolated by shale deposits in the valley. This depositional setting contrasts markedly with predominantly fluvial reservoirs in updip regions of the valleys. Understanding the scale, geometry, and internal complexity of this depositional system is important because the associated sandstones are important gas reservoirs in southwest Kansas. Cores, wire-line logs, pressure data, and production data collected from the Morrow Formation at Nicholas and Liverpool Cemetery fields provide valuable information from which to describe and interpret this downdip valley fill. This paper describes the downdip incised-valley-fill reservoirs in this producing complex and documents the trapping relationships of these reservoirs and their production characteristics.
Room temperature operation of Si single-electron memory with self-aligned floating dot gate (1997)

We have developed an excellent fabrication method for a Si single-electron field effect transistor memory device having a self-aligned floating dot gate. This device demonstrates single electron memory operation at room temperature. The ability to precisely control the size and position of the floating dot gate and the channel indicates the feasibility of practical single-electron memory.

Mechanistic and catalytic studies of β‐nitroalcohol crosslinking with polyamine (2012)

<i>β</i>-Nitroalcohols (<i>β</i>NAs) are promising corneoscleral crosslinking agents for the treatment of diseases such as keratoconus and myopia. Although it is believed that formaldehyde is released from the crosslinking reactions of <i>β</i>NAs, the mechanism by which <i>β</i>NAs react with amine-functionalized polymers has yet to be known. In this study, we present the reaction mechanism of the <i>β</i>NA crosslinking. Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) data provide strong evidence that formaldehyde is released during the reaction. Catalytic studies show that sodium bicarbonate (NaHCO<sub>3</sub>) and salmon testes DNA accelerate the reaction while hydroxynitrile lyase from Arabidopsis thaliana decelerates the crosslinking reaction. These results suggest that <i>β</i>NAs are potential self-administered crosslinking agents for future clinical use.
Assessment of Enterprise Information Security - An Architecture Theory Diagram Definition - (2005)

In order to manage and improve something, it is normally necessary to be able to assess the current state of affairs. A problem with assessment, however, is that in order to assess, it is normally necessary to be able to define the assessment topic. These general statements are also true within the area of Enterprise Information Security. Although much has been written on the topic, there is little consensus on what Enterprise Information Security really is. The lack of consensus lessens the credibility of existing assessment approaches. This paper presents a well-defined, transparent, and quantified method for the assessment of Enterprise Information Security. The method is based on the consolidation of the most prominent sources on the topic and results in a single quantitative estimate of the level of Enterprise Information Security in a company. The usefulness of the presented method has been verified by a case study at a large European electric utility. The present paper is a part of an ongoing research project on a credible and cost-effective method for Enterprise Information Security assessment. 1. Background to research This paper presents results from an on-going research project that focuses on the development of a method for the assessment of Enterprise Information

Translational approaches targeting the p53 pathway for anti‐cancer therapy (2011)

The p53 tumour suppressor blocks cancer development by triggering apoptosis or cellular senescence in response to oncogenic stress or DNA damage. Consequently, the p53 signalling pathway is virtually always inactivated in human cancer cells. This unifying feature has commenced tremendous efforts to develop p53-based anti-cancer therapies. Different strategies exist that are adapted to the mechanisms of p53 inactivation. In p53-mutated tumours, delivery of wild-type p53 by adenovirus-based gene therapy is now practised in China. Also, remarkable progress has been made in the development of p53-binding drugs that can rescue and reactivate the function of mutant or misfolded p53. Other biologic approaches include the development of oncolytic viruses that are designed to specifically replicate in and kill p53-defective cells. Inactivation of wt-p53 frequently results from dysregulation of MDM2, an E3 ligase that regulates p53 levels. Small-molecule drugs that inhibit the interaction of MDM2 and p53 and block p53 degradation are currently tested in clinical trials. This survey highlights the recent developments that attempt to modulate the function of p53 and outlines strategies that are being investigated for pharmacological intervention in the p53 pathway.
Establishment of an in Vitro Peyer's Patch Cell Culture System Correlative to in Vivo Study Using Intestine and Screening of Lactic Acid Bacteria Enhancing Intestinal Immunity (2010)

Some lactic acid bacteria (LAB) are known as representative of probiotics. To screen LAB effective to enhance intestinal immunity, in the present study, we developed an accurate and convenient in vitro evaluation system using Peyer's patch cells (PP-cells) isolated from the mice intestine. We observed that the amount of immunoglobulin A (IgA) produced by PP-cells co-cultured with LAB was well correlative to that in PP-cells, intestine and feces isolated from live mice after oral administration of LAB [correlation coefficient (r)=0.888, 0.883, and 0.920, respectively]. In addition, using this in vitro system, we suggest that the IgA level of PP-cells co-culturing with plant-derived LAB might be more enhanced than with animal-derived LAB.

Reflectance measurements of human skin from the ultraviolet to the shortwave infrared (250 nm to 2500 nm) (2013)

While published literature of the optical properties of human skin is prevalent for the visible region, data are sparse in the ultraviolet and shortwave infrared. Spectral imaging has expanded from primarily an earth remote sensing tool to a range of applications including medicine and security applications, as examples. These emerging applications will likely benefit from exemplar data of human skin spectral signatures that can be used in designing and testing spectral imaging systems. This paper details an initial study of the reflectance properties over the spectral range of the ultraviolet to the shortwave infrared. A commercial spectrophotometer was used to collect the directional-hemispherical reflectance of each participant’s skin from 250 nm to 2500 nm. The measurements are directly traceable to the national scales of reflectance and include estimated measurement uncertainties. The portion of skin under test was located on the participant’s forearm and was approximately 5 mm in diameter. The results provided in this study serve as one point of reference for the optical properties of skin that in turn will aid in the development of physical and digital tissue phantoms.
PARAMETER EXTRACTION OF ECG SIGNALS IN REAL-TIME (2002)

In order for a mobile ECG recorder to be able to classify a heart rhythm online, the significant parameters must be extracted. The relevant parameters are the beginning, peak and end of the QRS-complex, the P- and T-waves, the ST-segment and other significant intervals, such as the RR-interval. The aim of the development was, firstly, stable, real-time-capable QRS detection, which finally achieved values for sensitivity of 98.9% and a positive predictivity of 99.9% on standard ECG databases. Also, a filter-based detection of P- and T-waves was implemented, which can also be performed in real-time on a microcontroller platform.

Hypoxia-Inducible Factor Regulates Expression of Surfactant Protein in Alveolar Type II Cells <i>In Vitro</i> (2011)

Alveolar type II (ATII) cells cultured at an air-liquid (A/L) interface maintain differentiation, but they lose these properties when they are submerged. Others showed that an oxygen tension gradient develops in the culture medium as ATII cells consume oxygen. Therefore, we wondered whether hypoxia inducible factor (HIF) signaling could explain differences in the phenotypes of ATII cells cultured under A/L interface or submerged conditions. ATII cells were isolated from male Sprague-Dawley rats and cultured on inserts coated with a mixture of rat-tail collagen and Matrigel, in medium including 5% rat serum and 10 ng/ml keratinocyte growth factor, with their apical surfaces either exposed to air or submerged. The A/L interface condition maintained the expression of surfactant proteins, whereas that expression was down-regulated under the submerged condition, and the effect was rapid and reversible. Under submerged conditions, there was an increase in HIF1α and HIF2α in nuclear extracts, mRNA levels of HIF inducible genes, vascular endothelial growth factor, glucose transporter-1 (GLUT1), and the protein level of pyruvate dehydrogenase kinase isozyme-1. The expression of surfactant proteins was suppressed and GLUT1 mRNA levels were induced when cells were cultured with 1 mM dimethyloxalyl glycine. The expression of surfactant proteins was restored under submerged conditions with supplemented 60% oxygen. HIF signaling and oxygen tension at the surface of cells appears to be important in regulating the phenotype of rat ATII cells.
Acid-Promoted Olefination of Ketones by an Iron(III) Porphyrin Complex (2003)

[reaction: see text] The acid-promoted olefination of unactivated ketones with diazo reagents in the presence of triphenylphosphine can be catalyzed by the commercially available iron(III) porphyrin complex Fe(TPP)Cl. The reactions were effectively carried out under mild conditions in a one-pot fashion with the use of a stoichiometric diazo reagents and substoichiometric benzoic acid. Examples include aromatic, aliphatic, cyclic, and unsaturated ketones with ethyl diazoacetate or tert-butyl diazoacetate.
Reversible cyclisation of ortho-blocked N-arylnitroso-imines (1975)

N-Aryl-C-nitroso-imines (1), in which the ortho positions of the N-aryl substituent are occupied by methyl groups, undergo rapid but reversible ring-closure to the 1,2,4-oxadiazines (3); the nitroso-imines can be intercepted in a Diels–Alder reaction with thebaine, whereas the tautomers (3) slowly dimerise.
