Expanding the Family of Grassmannian Kernels: An Embedding Perspective (2014)

Modeling videos and image-sets as linear subspaces has proven beneficial for many visual recognition tasks. However, it also incurs challenges arising from the fact that linear subspaces do not obey Euclidean geometry, but lie on a special type of Riemannian manifolds known as Grassmannian. To leverage the techniques developed for Euclidean spaces (e.g, support vector machines) with subspaces, several recent studies have proposed to embed the Grassmannian into a Hilbert space by making use of a positive definite kernel. Unfortunately, only two Grassmannian kernels are known, none of which -as we will show- is universal, which limits their ability to approximate a target function arbitrarily well. Here, we introduce several positive definite Grassmannian kernels, including universal ones, and demonstrate their superiority over previously-known kernels in various tasks, such as classification, clustering, sparse coding and hashing.
Impact of exposure to parental attention-deficit hyperactivity disorder on clinical features and dysfunction in the offspring (2002)

These results find no support for the hypothesis that exposure to parental ADHD increases the risk for ADHD in children beyond that conveyed by the liability associated with the diagnosis in the parent. However, since exposure to parental ADHD was associated with a disruptive family environment, the identification and treatment of adults with ADHD may be an important component of the treatment plan of youth with ADHD.
On Foot Navigation: When GPS Alone is Not Enough (2000)

Integration of GPS/INS navigation systems is a common topic for aeronautical and road applications. The use of these technologies for personal localisation requires more than just portable sensors and a change of ergonomics; it requires a totally different approach for dead reckoning algorithms. This paper will focus on different human applications and reveals the particular problem encountered.
Management Levers for Product Platforms (2017)

Platforming has become an important means of cost-sharing among industrial products. However, many firms face systemic downward pressure on commonality, with the result that many platforms realize less commonality than intended. Past research has hypothesized that divergence is the result of conflicting tensions between product customization/optimization and cost control. This article investigates the control and incentive levers available to platform managers to shape the behavior of the organization when divergence opportunities arise. Management levers are drawn from a series of 12 industrial case studies, stemming from investigations of the causes of divergences. These management levers are categorized as technical levers, financial levers, and organizational levers. This article illustrates each of the management levers with examples from the case studies.
Newborn screening for homocystinurias and methylation disorders: systematic review and proposed guidelines (2015)

Newborn screening (NBS) is justified if early intervention is effective in a disorder generally not detected early in life on a clinical basis, and if sensitive and specific biochemical markers exist. Experience with NBS for homocystinurias and methylation disorders is limited. However, there is robust evidence for the success of early treatment with diet, betaine and/or pyridoxine for CBS deficiency and good evidence for the success of early betaine treatment in severe MTHFR deficiency. These conditions can be screened in dried blood spots by determining methionine (Met), methionine-to-phenylanine (Met/Phe) ratio, and total homocysteine (tHcy) as a second tier marker. Therefore, we recommend NBS for cystathionine beta-synthase and severe MTHFR deficiency. Weaker evidence is available for the disorders of intracellular cobalamin metabolism. Early treatment is clearly of advantage for patients with the late-onset cblC defect. In the early-onset type, survival and non-neurological symptoms improve but the effect on neurocognitive development is uncertain. The cblC defect can be screened by measuring propionylcarnitine, propionylcarnitine-to-acetylcarnitine ratio combined with the second tier markers methylmalonic acid and tHcy. For the cblE and cblG defects, evidence for the benefit of early treatment is weaker; and data on performance of Met, Met/Phe and tHcy even more limited. Individuals homozygous or compound heterozygous for MAT1A mutations may benefit from detection by NBS using Met, which on the other hand also detects asymptomatic heterozygotes. Clinical and laboratory data is insufficient to develop any recommendation on NBS for the cblD, cblF, cblJ defects, glycineN-methyltransferase-, S-adenosylhomocysteinehydrolase- and adenosine kinase deficiency.
The Drosophila takeout gene is regulated by the somatic sex-determination pathway and affects male courtship behavior (2002)

The Drosophila somatic sex-determination regulatory pathway has been well studied, but little is known about the target genes that it ultimately controls. In a differential screen for sex-specific transcripts expressed in fly heads, we identified a highly male-enriched transcript encoding Takeout, a protein related to a superfamily of factors that bind small lipophilic molecules. We show that sex-specific takeout transcripts derive from fat body tissue closely associated with the adult brain and are dependent on the sex determination genes doublesex (dsx) and fruitless (fru). The male-specific Doublesex and Fruitless proteins together activate Takeout expression, whereas the female-specific Doublesex protein represses takeout independently of Fru. When cells that normally express takeout are feminized by expression of the Transformer-F protein, male courtship behavior is dramatically reduced, suggesting that male identity in these cells is necessary for behavior. A loss-of-function mutation in the takeout gene reduces male courtship and synergizes with fruitless mutations, suggesting that takeout plays a redundant role with other fru-dependent factors involved in male mating behavior. Comparison of Takeout sequences to the Drosophila genome reveals a family of 20 related secreted factors. Expression analysis of a subset of these genes suggests that the takeout gene family encodes multiple factors with sex-specific functions.
Optimal design of a CMOS op-amp via geometric programming (2001)

We describe a new method for determining component values and transistor dimensions for CMOS operational amplifiers (op-amps). We observe that a wide variety of design objectives and constraints have a special form, i.e., they are posynomial functions of the design variables. As a result, the amplifier design problem can be expressed as a special form of optimization problem called geometric programming, for which very efficient global optimization methods have been developed. As a consequence we can efficiently determine globally optimal amplifier designs or globally optimal tradeoffs among competing performance measures such as power, open-loop gain, and bandwidth. Our method, therefore, yields completely automated sizing of (globally) optimal CMOS amplifiers, directly from specifications. In this paper, we apply this method to a specific widely used operational amplifier architecture, showing in detail how to formulate the design problem as a geometric program. We compute globally optimal tradeoff curves relating performance measures such as power dissipation, unity-gain bandwidth, and open-loop gain. We show how the method can he used to size robust designs, i.e., designs guaranteed to meet the specifications for a variety of process conditions and parameters.
OS0814 A study on electric resistance welding of CFRTP (2011)

CFRTP (Carbon fiber reinforced thermoplastic) has the superior properties such as high toughness, high productivity, recycling efficiency and repairability when compared with CFRP (Carbon fiber reinforced plastic). Another advantage of CFRTP is its weldability. Although several welding methods, such as resistance welding, ultrasonic welding and induction welding have been proposed, a new welding method which using electrical resistance of material itself is proposed in the study. In other words, electric current is loaded on through-thickness direction of single lap joint, and resin of welding area is melting. In this method, electric resistance of joint part is peak in the current pathway, welding area can be preferentially heated up. In this study, spot welding and surface welding were conducted. Tensile lap-shear tests were conducted for CFRTP joints welded by the proposed method. As a result, the tensile lap-shear strength (LSS) of spot welding is 31.0MPa and LSS of surface welding is 22.0MPa. Also, LSS is changed with welding pressure of joint parts.
Lamivudine as Initial Treatment for Chronic Hepatitis B in the United States (1999)

In U.S. patients with previously untreated chronic hepatitis B, one year of lamivudine therapy had favorable effects on histologic, virologic, and biochemical features of the disease and was well tolerated. HBeAg responses were generally sustained after treatment.
Utilization of Splicing Elements and Polyadenylation Signal Elements in the Coupling of Polyadenylation and Last-Intron Removal (1999)

Polyadenylation (PA) is the process by which the 3' ends of most mammalian mRNAs are formed. In nature, PA is highly coordinated, or coupled, with splicing. In mammalian systems, the most compelling mechanistic model for coupling arises from data supporting exon definition (2, 34, 37). We have examined the roles of individual functional components of splicing and PA signals in the coupling process by using an in vitro splicing and PA reaction with a synthetic pre-mRNA substrate containing an adenovirus splicing cassette and the simian virus 40 late PA signal. The effects of individually mutating splicing elements and PA elements in this substrate were determined. We found that mutation of the polypyrimidine tract and the 3' splice site significantly reduced PA efficiency and that mutation of the AAUAAA and the downstream elements of the PA signal decreased splicing efficiency, suggesting that these elements are the most significant for the coupling of splicing and PA. Although mutation of the upstream elements (USEs) of the PA signal dramatically decreased PA, splicing was only modestly affected, suggesting that USEs modestly affect coupling. Mutation of the 5' splice site in the presence of a viable polypyrimidine tract and the 3' splice site had no effect on PA, suggesting no effect of this element on coupling. However, our data also suggest that a site for U1 snRNP binding (e.g., a 5' splice site) within the last exon can negatively effect both PA and splicing; hence, a 5' splice site-like sequence in this position appears to be a modulator of coupling. In addition, we show that the RNA-protein complex formed to define an exon may inhibit processing if the definition of an adjacent exon fails. This finding indicates a mechanism for monitoring the appropriate definition of exons and for allowing only pre-mRNAs with successfully defined exons to be processed.
Facial Expression Recognition Based on LBP-EHMM (2008)

Facial expression recognition can be divided into three steps: face detection, expression feature extraction and expression categorization. Facial expression feature extraction and categorization are the most key issue. To address this issue, we propose a method to combine local binary pattern (LBP) and embedded hidden markov model (EHMM), which is the key contribution of this paper. This paper first gives an introduction about facial expression recognition and then describes EHMM and LBP. Finally, we give out the LBP-EHMM method in facial expression recognition, and perform an experiment to obtain a comparison between LBP feature and discrete cosine transform (DCT) feature.
Discrete diffraction in two-dimensional arrays of coupled waveguides in silica (2004)

The propagation of light in 5 x 5 and 7 x 7 cubic lattices of evanescently coupled waveguides is investigated for the first time, to the authors' knowledge. The results reveal ideal discrete diffraction and demonstrate the excellent quality of the waveguide arrays, which were manufactured in fused silica by femtosecond-laser-induced refractive-index modifications.
Issues with Comparing SARA Methodologies (2007)

One of the most common compositional analyses for petroleum samples is known as the SARA (saturates, aromatics, resins, and asphaltenes) fractionation test. SARA fractionation is also used as one of the screening criteria for asphaltene stability of reservoir fluids due to pressure depletion or commingling of different fluids. There are numerous variations of this type of analysis. First, the extraction of asphaltenes is not consistent from method to method. Asphaltenes are extracted using either pentane, hexane, or heptane. There are no specific reasons for selecting one over the other, and usually the users do not associate differences in results with the nature of the solvent. In addition, the extraction temperature could have an impact on the amounts of asphaltenes extracted. The fractionation of maltenes is also a challenge, usually ignored by end-users. Assuring no overlap between fractions and obtaining a very good mass balance are among these challenges. They could be impacted by the type of packing material amount of solvents used for the chromatographic separation. These SARA methods, referred to as standard methods, usually generate different results leading to confusion if the users are not that familiar with analytical details of each method. This paper discusses the role of the major parameters involved in generating the four fractions and how these parameters affect results, thus impacting decision for the end-users. It also shows that it is impossible to perform any prediction of results when changing from one method to another.
Evolução da onda P do eletrocardiograma após valvoplastia mitral em pacientes portadores de sobrecarga atrial esquerda (2006)

ECG changes suggestive of LAE regress in the majority of patients with MS and sinus rhythm that undergo a successful PMV. An MVA > or = 1.7 cm2 at late follow-up was found to be an independent predictor of such normalization.
Outage Analysis of Block-Fading Gaussian Interference Channels (2011)

This paper considers the asymptotic behavior of the outage probability of a two-source block-fading single-antenna Gaussian interference channel in the high-SNR regime by means of the diversity-multiplexing tradeoff. A general setting where the user rates and the average channel gains are not restricted to be symmetric is investigated. This asymmetric scenario allows to analyze networks with “mixed” interference, i.e., when different sources are at different distance from their intended destination, that are not possible under the commonly used symmetric assumption. Inner and outer bounds for the diversity are derived. The outer bound is based on the recent “to within one bit” capacity result of Etkin for the unfaded Gaussian channel and is a re-derivation of a known bound for which an error is pointed out. The inner bound is based on the Han and Kobayashi achievable region both without rate splitting and with a rate spitting inspired by the “to within one bit” capacity result. An analytical comparison of the diversity upper and lower bounds for a general channel seems difficult; by numerical evaluations, the two bounds are shown to coincide for a fairly large set of channel parameters.
Electrophilic 1,5-Addition of Acyl Chlorides to Conjugated Azocyclopropanes (1994)

Addition reactions of acetyl and benzoyl chlorides to 1-pyrazolines containing a spiro cyclopropane fragment at the adjacent azo group lead selectively and in high yields to the corresponding 1-acyl-3-(chloroethyl)-2-pyrazolines, resulting in opening of the three-membered ring.
Brain-Machine Interfaces for Motor Control: A Guide for Neuroscience Clinicians (2012)

With the growing interdependence between medicine and technology, the prospect of connecting machines to the human brain is rapidly being realized. The field of neuroprosthetics is transitioning from the proof of concept stage to the development of advanced clinical treatments. In one area of brain-machine interfaces (BMIs) related to the motor system, also termed 'motor neuroprosthetics', research successes with implanted microelectrodes in animals have demonstrated immense potential for restoring motor deficits. Early human trials have also begun, with some success but also highlighting several technical challenges. Here we review the concepts and anatomy underlying motor BMI designs, review their early use in clinical applications, and offer a framework to evaluate these technologies in order to predict their eventual clinical utility. Ultimately, we hope to help neuroscience clinicians understand and participate in this burgeoning field.
Cold Roll Forming - Engineers' Dilemma and Artisans' Art (1985)

In cold roll forming a sheet or strip of metal is formed into desired shapes by feeding the strip through successive pairs of rolls arranged in tandem. Each pair of rolls imparts an incremental amount of deformation on the workpiece passing through and the strip progressively deforms until the prescribed cross-section is produced. The deformation mechanisms of the process are very complex and often very crude empirical methods are employed to generate the design data. However, a successful operation depends very much on the designer's experience and often entails lengthy 'trial and error' approach. The present paper highlights the fundamentals of deformation mechanisms and discusses the research carried out overseas and at the Auckland University. The significance of this research to the optimization of the roll pass schedule and as a whole to the roll forming industry has been pointed out. The future role of a computer in the selection of roll pass schedules and in the subsequent design of rolls has been discussed.
MEGA: Microlensing Exploration of the Galaxy and Andromeda (2004)

Microlensing surveys have ruled out that the dark halos of the Milky Way and M31 are composed entirely of massive compact halo objects (MACHOs) for a wide range of MACHO masses. We have tried using the Subaru telescope to improve the limit on Moon-mass MACHOs, which is the lowest decade in MACHO mass that can be probed by microlensing. Unfortunately, only a half-night of Subaru data was obtained and this is not enough; at least 2 nights of data are required. the current limit is based on nearly 6 years of observations with smaller telescopes.
Simulation of the NRIM Continuous Steelmaking Process (1977)

A mathematical model of the NRIM continuous steelmaking process has been developed on the basis of the assumption that the rate limiting step in the steelmaking reaction is mass transfer which is the function of flow rates of jetted oxygen and generated CO gas. Resistance constants in mass transfer equations and other system parameters used in the model are determined by the complex optimization method to get a good agreement with the actual data in steady state. Results applied for the start-up simulations for the NRIM process operations show that the model can represent the actual process with accuracy. This means that the parameter constants in steady state are available for the unsteady state simulation, so that the model can be used for an optimal designing of the continuous steelmaking process and for the development of the process control strategy. Moreover, the assumption that the gas flow rates have an important role for bath mixing can provide a valuable aid to understand the steelmaking reaction kinetics.

Purification and Characterization of Proteasomes from Saccharomyces cerevisiae (2001)

The proteasome plays a central role in eukaryotic cells since it is responsible for the degradation of specific proteins involved in a large range of cellular processes. Analysis of proteasome mechanisms of action, or in vitro reconstitution, or dissection of the complex biological pathways in which it partakes, requires a reliable source of pure active proteasome. Although the biologically relevant form of the proteasome is usually considered to be the 26S proteasome, this unit describes different methods for purification and study of both 26S and 20S proteasomes from Saccharomyces cerevisiae cells.
Supply chain control: trade-offs and system requirements (1997)

This paper describes the underlying forces which drive change in manufacturing enterprises and supply chains. It sets out the complexities in modern capitalism and global economics and illustrates the trade-offs that can be made. IT systems which are required to assist improvements to both customer service and enterprise manufacturing performance are explained alluding to the special case for the semiconductor industry. Finally it shows how the new tools being developed with the ESPRIT project 20544, X-CITTIC, will satisfy the control needs for a virtual enterprise.
