Face feature detection and model design for 2D scalable model-based video coding (2003)

This paper addresses our proposed methods for face feature detection and 2D scalable face model design in order to achieve scalable model-based video coding. Firstly, fast and reliable algorithms have been proposed for eye, mouth and chin detection. Then, based on the detected face features and human face muscular distribution, a heuristic scalable face model is designed. Experimental results show that this scalable face model can represent face motion precisely.
Domain description grammar: application of linguistic semantics (1990)

Domain descriptions should represent more than the characteristics of data and the operations on it. They should be "semantic" in the sense that they may represent information such as the meanings of special terms used in the business, as well as goals and rules. ER models are often described as "semantic data models". However, the correspondence between ER and natural language is through syntactic rather than through semantic constructs. Conceptual modeling languages and knowledge representation techniques are more appropriate for representing domain meaning. Modern research in linguistics, semantics, and artificial intelligence provides valuable insight into basic issues regarding such representations. Domain descriptions must use languages based on generally-accepted linguistic and knowledge representation principles.
Regulatory Effect of Cytokine Production in Patients with Cerebral Infarction by Yulda-Hanso-Tang (2000)

Yulda-Hanso-Tang (YH-Tang) is a prescription for the Taeumin cerebral infarction (CI) patients according to Sasang constitution philosophy. Taeumin patients with CI were treated with YH-Tang during the acute stage. Clinical signs of CI disappeared markedly in about 2 weeks after oral administration of YH-Tang in all patients. The mean interleukin (IL)-2 serum levels were lower in the patients with CI than in the normal groups, whereas the mean IL-4, IL-6 and IgE levels were significantly higher in the patients. There were no significant differences in interferon-gamma (IFN-gamma) levels between the groups. Serum IFN-gamma and IL-2 levels derived from T helper (Th)1 cells elevated significantly in the patients with CI by YH-Tang administration. Significant reduced serum levels of IL-4 and IL-6 derived from Th2 cells and IgE were observed in the patients treated with YH-Tang. During the period of YH-Tang administration, there were no other adverse effects. The data indicate that YH-Tang has a good CI treatment effect, and that its action may be due to regulation of cytokine production.
Power gating (2010)

Power Gating has become one of the most widely used circuit design techniques for reducing leakage current. Its concept is very simple, but its application to standard-cell VLSI designs involves many careful considerations. The great complexity of designing a power-gated circuit originates from the side effects of inserting current switches, which have to be resolved by a combination of extra circuitry and customized tools and methodologies. In this tutorial we survey these design considerations and look at the best practice within industry and academia. Topics include output isolation and data retention, current switch design and sizing, and physical design issues such as power networks, increases in area and wirelength, and power grid analysis. Designers can benefit from this tutorial by obtaining a better understanding of implications of power gating during an early stage of VLSI designs. We also review the ways in which power gating has been improved. These include reducing the sizes of switches, cutting transition delays, applying power gating to smaller blocks of circuitry, and reducing the energy dissipated in mode transitions. Power Gating has also been combined with other circuit techniques, and these hybrids are also reviewed. Important open problems are identified as a stimulus to research.
A Comparison of Time Series Model Forecasting Methods on Patent Groups. (2015)

The ability to create forecasts and discover trends is a value to almost any industry. The challenge comes in finding the right data and the appropriate tools to analyze and model such data. This paper aims to demonstrate that it may be possible to create technology forecasting models through the use of patent groups. The focus will be on applying time series modeling techniques to a collection of USPTO patents from 1996 to 2013. The techniques used are Holt-Winters Exponential Smoothing and ARIMA. Cross validation methods were used to determine the best fitting models and ultimately whether or not patent data could be modeled as a time series.
Rhythm and Vowel Quality in Accents of English (2010)

This paper will examine rhythmic differences among native and non-native accents of English, and report on a pilot experiment investigating a hypothesized interaction between rhythm and vowel quality. A new metric, % SteadyState, an acoustic measure that quantifies the purity of vowels, appears to capture rhythmic differences that have been reported among various native and non-native accents of English. In the tradition of other recently developed rhythm metrics, these findings suggest a link between rhythm and segmental phonology. Additionally, the perspective gained from this study may be beneficial to learners whose goal is native-like vowel quality, offering an understanding of the dynamic properties of English vowels.
Field-Oriented Control of a Standard AC Motor Using Microprocessors (1980)

Field orientation has emerged as a powerful tool for controlling ac machines such as inverter-supplied induction motors. The dynamic performance of such a drive is comparable to that of a converterfed four quadrant dc drive. The complex functions required by filed-oriented control may be executed by microprocessors on line, thus greatly reducing the necessary control hardware. It is shown that the flux signals may be derived from sensing coils or, with some compromise in performance, from the stator voltages and currents. The speed signal is obtained from a digital tachometer. Results from a 2-kW experimental drive are given.
A role for CDC7 in repression of transcription at the silent mating-type locus HMR in Saccharomyces cerevisiae. (1991)

The mating-type genes at MAT in Saccharomyces cerevisiae are expressed, whereas the same genes located at HML and HMR are transcriptionally repressed. The DNA element responsible for repression at HMR has been termed a silencer and contains an autonomous replication sequence, a binding site for GRFI/RAPI, and a binding site for ABFI. A double-mutant HMR-E silencer that contains single nucleotide substitutions in both the GRFI/RAPI- and ABFI-binding sites no longer binds either factor in vitro, nor represses transcription at HMR in vivo. In MAT alpha cells, this derepression of a information results in a nonmating phenotype. Second-site suppressor mutations were isolated that restored the alpha mating phenotype to MAT alpha cells containing the double-mutant silencer. One of these suppressors, designated sas1-1, conferred a temperature-sensitive lethal phenotype to the cell. SAS1 was found to be identical to CDC7, a gene which encodes a protein kinase required for the initiation of DNA replication. This new allele of CDC7 was designated cdc7-90. cdc7-90 restored the alpha mating phenotype by restoring silencing. The original allele of CDC7, isolated on the basis of the cell cycle phenotype it confers, also restored silencing, and overexpression of CDC7 interfered with silencing. cdc7-90 did not restore detectable binding of GRFI/RAPI or ABFI to the double-mutant silencer in vitro. These results indicate that a reduced level of CDC7 function restores silencing to a locus defective in binding two factors normally required for silencing.
Shock-induced damage to mitochondrial function and some cellular antioxidant mechanisms in humans. (1985)

The effects of circulatory shock on skeletal muscle mitochondrial oxidative activity in various substrates and cytochrome oxidase activity have been investigated using samples of muscle obtained by the needle biopsy technique from human subjects. The effect of shock on superoxide dismutase activity and glutathione content of skeletal muscle was also examined. The results show that there is a large decrease in cytochrome oxidase activity during shock and also in the capacity of the mitochondria to oxidize either succinate, or pyruvate, or palmitoyl carnitine. There is a fall in the tissue content of superoxide dismutase and in the total glutathione present. Furthermore, an increased oxidized glutathione content causes a decrease in the molar ratio of reduced to oxidized glutathione present in the muscle. These findings suggest that mitochondrial electron transport chain (ETC) oxidative damage can play a relevant role in the pathogenesis of circulatory shock and support the hypothesis of oxygen-free radical involvement in the cellular injury.
Capillary filtration‐absorption balance reconsidered in light of dynamic extravascular factors (1991)

The evidence for the functional importance of extravascular Starling pressures now seems overwhelming, and when these terms are taken into account it is difficult to uphold the traditional conception that upstream microvascular filtration is largely matched by a sustained downstream reabsorption. Transient absorption can occur, however, during spontaneous vasomotion cycles, during sympathetic-induced vasoconstriction and during hypovolaemic hypotension. Sustained absorption is possible in specialized tissues where the interstitium is 'flushed' by an independent stream (intestinal mucosa, renal cortex, lymph nodes). Both theory and experiment show, however, that absorption cannot be maintained across most low-pressure exchange segments due to the finite permeability of microvessels to plasma protein, which leads to a rise in pericapillary interstitial oncotic pressure with time around absorbing microvascular segments. Extravascular hydraulic resistance may be a further determinant of net fluid transfer rate in situations where capillary wall resistance is low.

The ToxTracker Assay: Novel GFP Reporter Systems that Provide Mechanistic Insight into the Genotoxic Properties of Chemicals (2011)

People are exposed to an ever-increasing number of chemical compounds that are developed by industry for a wide range of applications. These compounds may harmfully react with different cellular components and activate specific defense mechanisms that provide protection against the toxic, mutagenic, and possibly oncogenic consequences of exposure. Monitoring the activation of specific cellular signaling pathways upon exposure may therefore allow reliable and mechanism-based assessment of potential (geno)toxic properties of chemicals, while providing insight into their primary mode of toxicity. By whole-genome transcription profiling of mouse embryonic stem cells, we identified genes that were transcriptionally activated upon exposure to either genotoxic compounds or pro-oxidants. For selected biomarker genes, we constructed reporters encoding C-terminal green fluorescent protein (GFP)-tagged fusion proteins. GFP reporter genes were located on bacterial artificial chromosomes, thereby enabling transcriptional regulation of the reporters by their own physiological promoter. The Bscl2-GFP reporter is selectively activated after exposure to genotoxic agents and its induction is associated with inhibition of DNA replication and activation of the ataxia telangiectasia and Rad3-related protein signaling pathway. The Srxn1-GFP reporter is preferentially induced upon oxidative stress and is part of the nuclear factor (erythroid-derived 2)-like 2-antioxidant response pathway. The novel (geno)toxicity assay (ToxTracker) that utilize the differential responsiveness of various reporter cell lines will enable prediction of the primary reactive properties of known and unknown chemicals.
InGaN laser diodes with 50 mW output power emitting at 515 nm (2009)

We demonstrate direct green laser operation from InGaN based diodes at wavelengths as long as 515.9 nm with 50 mW output power in pulse operation. A factor of ∼10 defect reduction for the In-rich InGaN quantum wells based on improvements of the epitaxial growth process and design of the active layers on c-plane GaN-substrates makes it possible to demonstrate laser operation at room temperature. Micrometer-scale photoluminescence mappings and electro-optical measurements confirm the reduction of nonradiative defects in the emitting layers. The 11 μm broad-area gain-guided laser structures were driven in pulse operation to minimize thermal effects and to accurately measure the laser temperature dependence. The threshold current density was ∼9 kA/cm2 and the fitted slope efficiency had a value of ∼130 mW/A for an optical output up to 50 mW.
Low‐dose recombinant interleukin‐2 therapy in advanced multiple myeloma (1995)

In vitro data have demonstrated autologous T-lymphocytes with anti-tumour activity in multiple myeloma (MM). Therefore a phase I/II trial was conducted to study the feasibility, the effect on several immunological parameters, and the tumour response induction of low-dose recombinant interleukin-2 (rIL-2) in MM patients. 18 MM patients of advanced stages in progress, who had failed on standard chemotherapy received 9 x 10(6) IU/m2 rIL-2 twice daily on days 1 and 2 and 0.9 x 10(6) IU/m2 twice daily for 5 subsequent days per week subcutaneously from days 3 to 56 (repeated every 12 weeks until progression). Patients were treated for between 8 and 1086 + d (mean 241 d) without serious side-effects. 6/17 patients experienced tumour response (2/17 objective tumour mass reduction, 4/17 long-lasting stable disease following tumour progression before initiation of rIL-2 treatment). During therapy the number of eosinophils increased 15-fold, CD4+ T lymphocytes were activated as demonstrated by enhanced CD25 antigen expression, and CD56+ NK cells expanded in the peripheral blood. Furthermore, a diminished pre-treatment ratio of CD4+/CD8+ lymphocytes was normalized during rIL-2 treatment. NK cell activity and lymphokine activated killer (LAK) cell activity was significantly enhanced. Endogenous IL-2 production and elevated soluble IL-2 receptor serum concentrations were induced. Low-dose rIL-2 can stimulate immune enhancement in MM despite the characteristic tumour-induced immunodeficiency. The treatment has proven though limited efficacy in advanced MM. Because most of the responders experienced termination of tumour progression rather than tumour regression, rIL-2 maintenance of chemotherapy-induced remissions should be investigated.
A Group Neighborhood Average Clock Synchronization Protocol for Wireless Sensor Networks (2014)

Clock synchronization is a very important issue for the applications of wireless sensor networks. The sensors need to keep a strict clock so that users can know exactly what happens in the monitoring area at the same time. This paper proposes a novel internal distributed clock synchronization solution using group neighborhood average. Each sensor node collects the offset and skew rate of the neighbors. Group averaging of offset and skew rate value are calculated instead of conventional point-to-point averaging method. The sensor node then returns compensated value back to the neighbors. The propagation delay is considered and compensated. The analytical analysis of offset and skew compensation is presented. Simulation results validate the effectiveness of the protocol and reveal that the protocol allows sensor networks to quickly establish a consensus clock and maintain a small deviation from the consensus clock.
Emerging technologies and research challenges for 5G wireless networks (2014)

As the take-up of Long Term Evolution (LTE)/4G cellular accelerates, there is increasing interest in technologies that will define the next generation (5G) telecommunication standard. This article identifies several emerging technologies which will change and define the future generations of telecommunication standards. Some of these technologies are already making their way into standards such as 3GPP LTE, while others are still in development. Additionally, we will look at some of the research problems that these new technologies pose.
Interpretation driven salt scenario modelling with examples from the Dutch offshore and West Africa (2015)

Summary Historically, velocity model building (VMB) in salt terrains has followed a layer stripping progression, where interpretation is confined to defining salt boundaries with the primary focus on defining the macro attributes for the post-salt, salt & pre-salt volumes. The imposition these horizons have on local and deeper imaging has generally been of lesser importance to the construction of the macro model, whilst the bulk of the interpretation effort has followed final imaging. This may result in subsequent ambiguity over the influence of the overburden model on the final interpretation. We propose an alternative flow where significant interpretation effort is involved at an early stage during the VMB process in order to assess the effect of the overburden model on the final image. This leads to the dual advantage of a progressive interpretation phase combined with increased confidence in the reliability of the final interpretation.
Improved Tire Wet Traction through the Use of Mineral Fillers (1999)

Abstract Silica is widely used in passenger tire treads to improve the balance between wet traction and rolling resistance, compared to the balance achieved when the filler is strictly carbon black. Improvement in wet traction with silica is attributed to the difference in energy loss encountered at high frequencies. The energy loss difference is deduced from the difference in shift factors, determined by time temperature superposition in viscoelastic testing of silica compounds compared to carbon black compounds. Further investigation indicated that some mineral fillers other than silica showed similar behavior. Thus, some mineral fillers could improve tire wet traction without adverse effects on other tire performance traits.
Batcher banyan network with cell copy preparation stages for multicast switching (2002)

Multicast services will occupy a large portion of the B-ISDN traffic. However, even if one multicast service is watched by many subscribers, it occupies only one channel on the trunkline as multicast traffic is not dominant on the trunkline. Therefore, it is a waste to use non-blocking multicast ATM switching networks for transit switching systems because the hardware of a non-blocking multicast ATM switching network is large. This paper proposes to apply the Batcher banyan network, which is point-to-point non-blocking, to multicast transit switching systems. The blocking rate decreases substantially by placing cell copy preparation stages in front of the Batcher network.
Preventing Annular Flow after Cementing, One Pulse at a Time: Offshore Gulf of Mexico Cement Pulsation Field Results (2005)

Abstract The initial offshore application of cement pulsation to prevent annular flow/pressure after cementing has been successfully performed in the Gulf of Mexico (GoM). This paper describes the methodology and cementing results achieved following application of the cement pulsation technology in multiple shallow offshore GoM casing strings. The compressible volume of the cement column is recorded during the pulsation operation, and this data can provide for surface monitoring of the downhole cement setting process. An overview of the equipment and cement pulsation pre-job design considerations are also included in this paper.
Predicted growth in plastic waste exceeds efforts to mitigate plastic pollution (2020)

Plastic pollution is a planetary threat, affecting nearly every marine and freshwater ecosystem globally. In response, multilevel mitigation strategies are being adopted but with a lack of quantitative assessment of how such strategies reduce plastic emissions. We assessed the impact of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at different levels of effort to estimate plastic emissions to 2030 for 173 countries. We estimate that 19 to 23 million metric tons, or 11%, of plastic waste generated globally in 2016 entered aquatic ecosystems. Considering the ambitious commitments currently set by governments, annual emissions may reach up to 53 million metric tons per year by 2030. To reduce emissions to a level well below this prediction, extraordinary efforts to transform the global plastics economy are needed.
Comparative Electrophoretic Analysis of the Virus Proteins of Four Rhabdoviruses (1974)

SUMMARY The structural proteins of vesicular stomatitis virus (VSV) Indiana, VSV New Jersey, Chandipura virus and Piry virus were compared by using two different SDS-polyacrylamide gel electrophoresis systems. The G and M proteins of the Indiana serotype had different electrophoretic mobilities from the corresponding proteins of VSV New Jersey, Chandipura virus and Piry virus in a continuous-SDS (CONT-SDS) gel system. The three major proteins of VSV Indiana G, N and M, were distinctly different from their counterpart proteins in the other three viruses when a high-resolution discontinuous-SDS (DISC-SDS) system was used. Chandipura and Piry virus glycoproteins migrated differently when co-electrophoresed in the CONT-SDS system, whereas both their N and M proteins were different in the DISC-SDS method. During infection both Chandipura and Piry viruses produced defective T particles which contained the same four structural proteins as virus particles.
Here Comes the Bride (1929)

"Here comes the bride\nAll dressed in white,"\nplays the orchestra from a sheltered corner of the palatial garden, while June's bride, blushing and sweet as a June rose itself, slowly advances along the rose-strewn path. The bridesmaids, garbed in filmy, pastel creations precede her to the arbor of nature's design.
On the Mechanism of Oxidation by Cuprous Chloride, Pyridine and Air. I. The Properties of the Reaction (1959)

Abstract (1) By aerial oxidation of aniline catalyzed by cuprous chloride in a pyridine solution, azobenzene of about 60% is produced. In this reaction, the actual oxidant may be considered “oxidant A” which is produced by aerial oxidation of cuprous chloride pyridine complex. (2) Hydroxy cupric chloride pyridine complex, a reaction product of cupric chloride pyridine complex with a methyl alcohol solution of potassium hydroxide, has a similar catalytic activity. (3) These two complexes are to be considered strong bases. (4) These two complexes have a remarkable resemblance to each other.
