A High-Performance Continuously Tunable MEMS Bandpass Filter at 1 GHz (2012)

This paper reports a continuously tunable lumped bandpass filter implemented in a third-order coupled resonator configuration. The filter is fabricated on a Borosilicate glass substrate using a surface micromachining technology that offers hightunable passive components. Continuous electrostatic tuning is achieved using three tunable capacitor banks, each consisting of one continuously tunable capacitor and three switched capacitors with pull-in voltage of less than 40 V. The center frequency of the filter is tuned from 1 GHz down to 600 MHz while maintaining a 3-dB bandwidth of 13%-14% and insertion loss of less than 4 dB. The maximum group delay is less than 10 ns across the entire tuning range. The temperature stability of the center frequency from -50°C to 50°C is better than 2%. The measured tuning speed of the filter is better than 80 s, and the is better than 20 dBm, which are in good agreement with simulations. The filter occupies a small size of less than 1.5 cm × 1.1 cm. The implemented filter shows the highest performance amongst the fully integrated microelectromechanical systems filters operating at sub-gigahertz range.
The Trading Costs of Early Earnings Release: The Case of Hewlett-Packard Company (2015)

Hewlett-Packard Company scheduled to announce its 2014 second quarter earnings after the market closed on May 22, 2014. However, its second quarter earnings report was accidently released earlier than scheduled. The lower than-expected revenue news dropped Hewlett-Packardâ€™s stock price by 5% within 6 minutes. The rare occurrence of an early earnings announcement during trading hours provides an opportunity to investigate the influence of early earnings release on trading costs of market participants. The results show that Hewlett-Packardâ€™s stock trading costs, measured by bid-ask spreads increased and its information asymmetry decreased after the early earnings release.

Dynamic Control of Electricity Cost with Power Demand Smoothing and Peak Shaving for Distributed Internet Data Centers (2012)

Internet based service providers, such as Amazon, Google, Yahoo etc, build their data centers (IDC) across multiple regions to provide reliable and low latency of services to clients. Ever-increasing service demand, complexity of services and growing client population cause enormous power consumptions by these IDCs incurring a major part of their running costs. Modern electric power grid provides a feasible way to dynamically and efficiently manage the electricity cost of distributed IDCs based on the Locational Marginal Pricing (LMP) policy. While recent works exploit LMP by electricity-price based geographic load distribution, the dynamic workload and high volatility of electricity prices induce highly volatile power demand and critical power peak problem. The benefit of cost minimization via geographic load distribution is counterbalanced with the high cost incurred by violating the peak power. In this paper, we study the dynamic control of electricity cost to provide low volatility in power demand and shaving of power peaks. To this end, a Model Predictive Control (MPC) electricity cost minimization problem is formulated based on a time-continuous differential model. The proposed solution minimizes electricity costs, provides low variation in power demand by penalizing the change in workload and alleviates the power peaks by tracking the available power budget. By providing extensive simulation results based on real-life electricity price traces we show the effectiveness of our approach.

Old yellow enzyme: Aromatization of cyclic enones and the mechanism of a novel dismutation reaction (1995)

The origin of charge transfer bands that develop on reaction of Old Yellow Enzyme with alpha,beta-unsaturated cyclic ketones such as 3-oxodecalin-4-ene (ODE, numbered according to the convention for steroids), 3-oxodecalin-4-ene-10-carboxaldehyde (ODEC), and 2-cyclohexenone is shown to be due to the aromatization of ODE and ODEC to 3-hydroxy-6,7,8,9-tetrahydronaphthalene (HTN) and of 2-cyclohexenone to phenol. The aromatization of ODEC to HTN is stereospecific and involves the trans dehydrogenation of the 1 beta, 2 alpha hydrogens. The aromatization occurs under aerobic as well as anaerobic conditions. With the exception of ODEC under aerobic conditions, the aromatization of these substrates is accompanied by a dismutation reaction in which the olefinic bond of a second molecule of each substrate is reduced to give the saturated cyclic ketone. Molecular oxygen may serve as the electron acceptor with ODEC and some other substrates under aerobic reaction conditions. The dismutation reaction involves an overall sequence of hydride transfer from one substrate molecule to the beta-carbon of a second substrate molecule along with a solvent proton uptake by the alpha-carbon. 19-Nortestosterone is aromatized to beta-estradiol; however, other 3-oxo-delta 4-steroids such as progesterone, testosterone, and androstene-3,17-dione bind tightly to the enzyme but are not aromatized. The NADPH-dependent reduction of the olefinic bond of alpha,beta-unsaturated carbonyl compounds is limited to aldehydes and ketones. alpha,beta-Unsaturated acids, esters, amides, and nitriles are not reduced. The reduction of the olefinic bond of ODE or cinnamaldehyde by NADPH occurs by an overall sequence of hydride transfer from the reduced pyridine nucleotide to the beta-carbon of the alpha,beta-unsaturated carbonyl compound and a solvent proton uptake by the alpha-carbon. The 4-pro-R hydride of NADPH is transferred in the reduction reaction. Structure-function relationships in the NADPH-dependent reduction of alpha,beta-unsaturated aldehydes or ketones indicate that increasing alkyl substitution at the beta-carbon results in marked decrease in the rate of reduction of the olefinic bond, consistent with a steric hindrance to hydride transfer at the beta-carbon.
Cyclin-Dependent Kinase 8 Positively Cooperates with Mediator To Promote Thyroid Hormone Receptor-Dependent Transcriptional Activation (2010)

Mediator is a multisubunit assemblage of proteins originally identified in humans as a coactivator bound to thyroid hormone receptors (TRs) and essential for thyroid hormone (T3)-dependent transcription. Cyclin-dependent kinase 8 (CDK8), cyclin C, MED12, and MED13 form a variably associated Mediator subcomplex (termed the CDK8 module) whose functional role in TR-dependent transcription remains unclear. Using in vitro and cellular approaches, we show here that Mediator complexes containing the CDK8 module are specifically recruited into preinitiation complexes at the TR target gene type I deiodinase (DioI) together with RNA polymerase II (Pol II) in a TR- and T3-dependent manner. We found that CDK8 is essential for robust T3-dependent Dio1 transcription and that CDK8 knockdown via RNA interference decreased Pol II occupancy, and also the recruitment of the Pol II kinase CDK9, at the DioI promoter. Chromatin immunoprecipitation revealed CDK8 occupancy at the DioI promoter concurrent with active transcription, thus suggesting CDK8 involvement in transcriptional reinitiation. Mutagenesis assays showed that CDK8 kinase activity is necessary for full T3-dependent DioI activation, whereas in vitro kinase studies indicated that CDK8 may contribute to Pol II phosphorylation. Collectively, our data suggest CDK8 plays an important coactivator role in TR-dependent transcription by promoting Pol II recruitment and activation at TR target gene promoters.

Antisense inhibition of glial S100 beta production results in alterations in cell morphology, cytoskeletal organization, and cell proliferation. (1990)

The phenotypic effects of selectively decreasing the levels of S100 beta in cultured glial cells were analyzed. Two separate antisense approaches were utilized for inhibition of S100 beta production: analysis of clonal isolates of rat C6 glioma cells containing an S100 beta antisense gene under the control of a dexamethasone-inducible promoter, and analysis of C6 cells treated with S100 beta antisense oligodeoxynucleotides. Both antisense methods resulted in a decrease in S100 beta levels in the cell, as measured by RIA. The inhibition of S100 beta production correlated with three alterations in cellular phenotype: (a) a flattened cell morphology; (b) a more organized microfilament network; and (c) a decrease in cell growth rate. The studies describe here provide direct evidence for an involvement of S100 beta in glial cell structure and function, and suggest potential in vivo roles for S100 beta in regulation of glial cell morphology, cytoskeletal organization, and cell proliferation.
High ERK Protein Expression Levels Correlate with Shorter Survival in Triple-Negative Breast Cancer Patients (2012)

The mitogen-activated protein kinase (MAPK) signaling pathway is known to be activated in triple-negative breast cancer (TNBC). Extracellular signal-related kinase (ERK), a member of the MAPK pathway, promotes cell proliferation, angiogenesis, cell differentiation, and cell survival. To assess the prognostic impact of ERK in TNBC patients, relative quantities of ERK (ERK-2 and pMAPK) and direct targets of the ERK pathway (MAPK/ERK kinase 1, phospho-enriched protein in astrocytes [PEA]-15, phosphorylated (p)PEA-15, tuberous sclerosis protein 2, p70S6 kinase, and p27) were measured using reverse-phase protein arrays in tumor tissue from patients with TNBC (n = 97) and non-TNBC (n = 223). Protein levels in patients with TNBC were correlated with clinical and tumor characteristics and outcome. The median age of patients with TNBC was 55 years (range, 27-86 years). Disease stage was I in 21%, II in 60%, and III in 20% of the patients. In a multivariate analysis, among patients with TNBC, those with ERK-2-overexpressing tumors had a lower overall survival rate than those with low ERK-2-expressing tumors (hazard ratio [HR], 2.76; 95% confidence interval [CI], 1.19-6.41). However, high pMAPK levels were associated with a significantly higher relapse-free survival rate (HR, 0.66; 95% CI, 0.46-0.95). In conclusion, ERK-2 and pMAPK are valuable prognostic markers in TNBC. Further studies are justified to elucidate ERK's role in TNBC tumorigenicity and metastasis.
Improved vector for promoter screening in lactococci (1991)

Fragments of Lactococcus lactis subsp. lactis NP45 chromosomal DNA provided promoter activity in Escherichia coli when cloned into the promoter probe vector pGKV210. Only 13% of these recombinant plasmids promoted detectable cat-86 activity when transferred to L. lactis, i.e., expressed chloramphenicol resistance. In these promoter-containing versions of pGKV210, the cat-86 gene specifies chloramphenicol-inducible chloramphenicol acetyltransferase expression. This could be a limiting factor for cloning of promoters with lower activity in L. lactis. Therefore, we have constructed a new promoter probe vector, pBV5030, with the mutated version of the cat-86 gene, which is constitutively expressed when transcriptionally activated by the insertion of a promoter. We found that in L. lactis IL1403 the constitutively expressed cat-86 gene (on a pBV5030 derivative) has four times higher activity than the inducible version of the same gene (on a pGKV210 derivative) when both have the same promoter inserted upstream of the cat-86 gene. These results suggest that plasmid pBV5030 could be a more efficient vector for the cloning of promoters from lactococci.

Porous Metals and Metallic Foams: Current Status and Recent Developments (2008)

Abstract Porous metals and metallic foams are presently the focus of very active research and development activities. There are currently around 150 institutions working on metallic foams worldwide, most of them focussing on their manufacture and characterisation. Various companies are developing and producing these materials which are now being used in numerous industrial applications such as lightweight structures, biomedical implants, filters, electrodes, catalysts, and heat exchangers. This review summarizes recent developments on these materials, with particular emphasis on research presented at the latest International Conference on Porous Metals and Metallic Foams (MetFoam 2007).

Hierarchical dual memory structure determines cognitive logic of the human brain (2008)

The present work provides a cognitive model revealed by the physiological structure of the human brain. A hierarchical dual memory structure underlies cognitive logic processing. Perceptual memory receives information from the physical world and represents physical information with a one-to-one correspondence. Conceptual memory receives information from the perceptual memory with a one-to-one correspondence. Induction is the acquisition process that relations are learned and memorized in between the two memories as knowledge. Deduction is the retrieval process from the perceptual information to its conceptual relations. Reduction is the retrieval process from conceptual information to its perceptual relations. This biological model has been applied as a computational model of the nondeterministic Turing machine successfully, which will be published separately.
Shape context based matching for hand gesture recognition (2010)

The shape context is often taken as a basis for shape matching. It can be regarded as a global characterization descriptor to represent the distribution of points in a set with scale and rotation invariance. In this paper, we developed a perceptual interface for human-computer-interaction based on real-time hand gesture recognition. User could interact with computer program by performing body gesture instead of physical contact. We use a shape context based approach for matching hand gestures. First, image of hand gesture was captured from video device. Then, shape information was extracted through computer vision techniques. After that, the hand gesture image was transformed into proper instruction according to the shape information. Finally, the instruction was transferred to an appropriate program to execute.
Automated Facial Expression Recognition System (2009)

Heightened concerns about the treatment of individuals during interviews and interrogations have stimulated efforts to develop ldquonon-intrusiverdquo technologies for rapidly assessing the credibility of statements by individuals in a variety of sensitive environments. Methods or processes that have the potential to precisely focus investigative resources will advance operational excellence and improve investigative capabilities. Facial expressions have the ability to communicate emotion and regulate interpersonal behavior. Over the past 30 years, scientists have developed human-observer based methods that can be used to classify and correlate facial expressions with human emotion. However, these methods have proven to be labor intensive, qualitative, and difficult to standardize. The Facial Action Coding System (FACS) developed by Paul Ekman and Wallace V. Friesen is the most widely used and validated method for measuring and describing facial behaviors. The Automated Facial Expression Recognition System (AFERS) automates the manual practice of FACS, leveraging the research and technology behind the CMU/PITT Automated Facial Image Analysis System (AFA) system developed by Dr. Jeffery Cohn and his colleagues at the Robotics Institute of Carnegie Mellon University. This portable, near real-time system will detect the seven universal expressions of emotion (figure 1), providing investigators with indicators of the presence of deception during the interview process. In addition, the system will include features such as full video support, snapshot generation, and case management utilities, enabling users to re-evaluate interviews in detail at a later date.
The Stereochemistry of Peptides Containing α-Aminoisobutyric Aci (1984)

The introduction of alpha-aminoisobutyric acid (Aib) into peptides dramatically limits the range of accessible backbone conformations. The presence of two geminal methyl groups at C alpha sterically compels Aib residues to largely favor structures in the right- or left-handed 3(10)/alpha-helical regions (phi approximately +/- 60 +/- 20 degrees, psi approximately +/- 30 +/- 20 degrees) of the peptide conformational map. Aib residues occur extensively in microbial peptides which form transmembrane channels. This observation has stimulated considerable interest in the stereochemistry of Aib peptides. This review summarizes theoretical studies on the conformations of Aib residues and examines the available data on solid-state structures, derived from single crystal X-ray diffraction studies. Crystal structures of over three dozen Aib-containing peptides, ranging in length from 2 to 11 residues, have been reported so far which exemplify various types of beta-turns, consecutive beta-turns, and helical structures. Examples of nonhydrogen bonded and cyclic structures are also described. The crystallographic results compare well with structural studies in solution, establishing that Aib peptides can provide rigid structural models for the development of spectroscopic methods of peptide conformational analysis.
Electrical Conductivity and Cation Valencies in Nickel Manganite (1982)

The change in the activation energy of the electrical properties of NiMn2O4 at about 400 °C and the sudden increase of the thermal expansion are indicative of the cation exchange between the octahedral and tetrahedral sublattices. During this exchange, the manganese ions have to change their valencies according to the reaction Mn + Mn + Ni → 2 Mn + Ni — 0.6 eV. This implies that the cation valencies in NiMn2O4 have to be represented with the formula NiMn(NiMnMn)O4. Die Änderung der Aktivierungsenergie der elektrischen Eigenschaften, die bei etwa 400 °C an NiMn2O4 gemessen werden, und der plötzliche Anstieg der thermische Ausdehnung sind Hinweise auf den Kationenaustausch zwischen dem oktaedrischen und dem tetraedrischen Teilgitter. Aus diesen Ergebnissen kann man weiter schließen, daß die Manganionen die Valenz während dieses Austausches ändern müssen : Mn + Mn + Ni → 2 Mn + Ni — 0,6 eV, und daß für NiMn2O4 die Wertigkeiten der Metallionen durch die Formel NiMn(NiMnMn)O4 dargestellt werden.
