The Maternal Abdominal ECG as Input to MICA in the Fetal ECG Extraction Problem (2011)

This letter presents a successful system for recovering the fetal electrocardiogram using multidimensional ICA (MICA). MICA requires as many observations as sources. To increase the number of observations, MICA is often applied to data sets that include measurements taken at the mother's thoracic region. However, experiments suggest that the propagation from the maternal heart to the mother's abdomen is not a simple delay, and that approach may fail. Alternatively, our method first estimates the maternal ECG directly from the mother's abdomen. Then, inputs this estimated ECG to MICA. Experiments show superior performance as compared with the traditional approach.
Frequency domain analysis of switching noise on power supply network (2000)

In this paper, we propose an approach for the analysis of power supply noise in the frequency domain for power/ground (P/G) networks of tree topologies. We model the P/G network as a linear time invariant (LTI) pseudo-distributed RLC network and the gates (or cells) as time-varying current sources. Voltage fluctuation caused by the switching events is calculated based on the effective impedances seen by the corresponding current sources and the spatial correlation between the nodes of the power network. Superposition is applied to the LTI system to obtain the overall noise spectrum at any node of the power supply network. Inverse Fast Fourier Transformation (IFFT) is then performed on the frequency domain noise spectrum to obtain the time domain noise waveform. The proposed algorithm has a complexity of O(n/sup 2/). Experimental results show that our approach can produce accurate noise waveforms.
Random Comments Concerning Silviculture (1937)

AT THE present time silviculture is practiced upon only a small percentage of the forest lands in the United States and most of the lands upon which it is practiced are those owned by public agencies. To many young men now studying forestry it may seem surprising that greater advance toward application in the woods has not been made during the period since the forestry movement started. However, as a matter of fact real field application of silviculture scarcely dates back 30 years. Good technical management of the national forests began when the U. S. Forest Service was created in the first decade of the present century and this marks the first application in this country of forestry methods on areas of any size. From the long range view point rapid progress has been made during these three decades, culminating in the achievements of the last few years.

Screening tests for coeliac disease. (1995)

Screening tests for coeliac disease Definition Coeliac disease is a permanent intolerance to dietary gluten in susceptible children, characterised by an inflam- matory enteropathy of the upper small intestine causing malabsorption and failure to thrive. Treatment with a gluten free diet results in clinical and mucosal recovery and subsequent gluten challenge provokes a clinical and mucosal relapse. ' Clinical features Most children with coeliac disease present before 2 years of age with a typical clinical picture of failure to thrive, anorexia, vomiting, abnormal stools, abdominal distension, muscle wasting, hypotonia, and irritability.2 However, gastrointestinal symptoms are less frequent in older children and adolescents, who may present with growth failure, an iron deficiency anaemia and delayed puberty, or occasionally with apparently unrelated dis- orders such as diabetes mellitus, arthritis, and recurrent apthous ulcers.3 Failure to recognise these diverse clinical on August 14,
Markov monitoring with unknown states (1994)

Pattern recognition methods and hidden Markov models can be effective tools for online health monitoring of communications systems. Previous work has assumed that the states in the system model are exhaustive. This can be a significant drawback in real-world fault monitoring applications where it is difficult if not impossible to model all the possible fault states of the system in advance. In this paper a method is described for extending the Markov monitoring approach to allow for unknown or novel states which cannot be accounted for when the model is being designed. The method is described and evaluated on data from one of the Jet Propulsion Laboratory's Deep Space Network antennas. The experimental results indicate that the method is both practical and effective, allowing both discrimination between known states and detection of previously unknown fault conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Dual-Energy CT in Patients Suspected of Having Renal Masses: Can Virtual Nonenhanced Images Replace True Nonenhanced Images? (2009)

In patients with renal masses, DE CT can provide high-quality VNE data sets, which are a reasonable approximation of TNE data sets. Integration of DE scanning into a renal mass protocol will lower radiation exposure by 35%.
Efficient generation of 1/f/sup α/ noise using a multi-rate filter bank (2004)

We propose a low-complexity 1/f/sup /spl alpha// noise generation scheme based on a multi-rate filter bank. In this scheme, each branch in the filter bank processes signals in a different frequency band and allows arbitrary selection of /spl alpha/ in each branch. This scheme greatly reduces computation when compared to the traditional noise generation approach of using a single noise shaping filter. Furthermore, it allows selecting different combinations of noise frequency response in different frequency bands, thus allowing calibration of noise generated in simulation to the one measured in the laboratory from test chips. A comparison of various noise generation schemes is also presented.
The Measurement of Anterior Knee Laxity After ACL Reconstructive Surgery (1985)

An objective clinical instrument known as a knee ligament Arthrometer was developed. The instrumentation system was applied to measurements of knee ligament laxity in the operating room with the patients under anesthesia. Prereconstruction and immediate postreconstruction measurements were made with the patient still on the operating table. The change in laxity of the patient's operated knee as compared to the opposite nonoperated control knee was documented for 19 chronic and 24 acute patients. Four separate reconstruction types were studied in the operating room. The immediate postreconstruction measurements documented that all four of the reconstruction types were equally effective in the immediate restoration of normal laxity in the ACL-deficient knees. The Arthrometer proved to be a useful tool for confirming that each patient's normal knee laxity was reestablished in the O.R. by its reconstruction.
Definitions of Culture: Losing Sight of the Forest for the Splinters? (2001)

The importance of understanding what we mean when we refer to culture is discussed. A variety of definitions of culture over last hundred years are examined, both from the historical and disciplinary perspective. It is concluded that the majority of definitions belong to a consistent tradition of thought, and that reductionist-structuralist thinking that has gained pre-eminence in the field of intercultural communication is out of step with this tradition. It is concluded that steps should be taken to reclaim this tradition and regain a broad and ‘synthetic’ view of culture. บทความนอภปรายความสำคญของการเขาถงสาระสำคญของคำวา “วฒนธรรม” จากการตรวจสอบนยามของคำวาวฒนธรรมซงมผใหคำอธบายไวเปนจำนวนมากเปนเวลานบหลายศตวรรษทผานมาและจากหลายสาขา ทำใหสรปไดวา นยามของคำวาวฒนธรรมโดยสวนใหญนนมสาระทสอดคลองทำนองเดยวกน มแตแนวคดของกลมรดกชนนสต-สตรกเชอรลลสต ซงมความโดดเดนตอการศกษาการสอสารขามวฒนธรรม ทไดใหคำนยามแนวคดและมมมองของวฒนธรรม ซงมความแตกตางจากแนวคดแบบเดมอยบาง กลาวโดยสรปหลกการสำคญของการเขาถงสาระของวฒนธรรมนนตองเกดจากการประสมประสานแนวคดเดมเขากบวธการมองวฒนธรรมในแนวใหมเพอใหสามารถเขาใจวฒนธรรมไดอยางคมชดและลกยงขน
The crystal and molecular structures of diferric porcine and rabbit serum transferrins at resolutions of 2.15 and 2.60 Å, respectively (2001)

The serum transferrins are monomeric proteins with a molecular mass of around 80 kDa and are responsible for the transport of iron in vertebrates. The three-dimensional structures of diferric porcine and rabbit serum transferrin have been refined against X-ray diffraction data extending to 2.15 and 2.60 A, respectively. Data for both proteins were collected using synchrotron radiation at temperatures of 277 K. The porcine protein crystallizes in the space group C2, with unit-cell parameters a = 223.8, b = 44.9, c = 78.9 A, beta = 105.4 degrees with one molecule in the asymmetric unit. The structure was solved by molecular-replacement methods using rabbit serum transferrin as the search model. The structure was refined using REFMAC, with a final residual of 13.8% (R(free) = 18.2% for a 5% data sample) for all data to 2.15 A. The final model comprises 5254 protein atoms, two Fe(3+) cations and two CO(3)(2-) anions, one N-acetyl glucosamine moiety and 494 water molecules. The rabbit protein crystallizes in space group P4(3)2(1)2, with unit-cell parameters a = 127.2, c = 144.9 A and one molecule per asymmetric unit. The structure was solved using the method of multiple isomorphous replacement and refined using REFMAC to give a final residual of 18.6% (R(free) = 22.2% for a 5% data sample) for all data to 2.60 A. The final model comprises 5216 protein atoms, two Fe(3+) cations and two CO(3)(2-) anions, a Cl(-) anion and 206 solvent molecules; there is no clear indication of the carbohydrate moiety attached to Asn490 (rabbit serum numbering). Both molecules adopt a bilobal structure typical for members of the transferrin family. Each of the structurally homologous lobes contains two dissimilar domains with a single iron-binding site buried within the interdomain cleft. The porcine serum protein lacks an interdomain disulfide bridge close to the connecting peptide between the lobes, but this seems to have little effect on the overall orientation of the lobes. The N-lobes of both proteins possess lysine residues, one from each of the two domains, that lie in close proximity to one another to form the so-called dilysine trigger. The more acid-labile release of iron from serum transferrins than from lactoferrins is discussed.
Voltage Drop Compensation Method for Active Matrix Organic Light Emitting Diode Displays (2011)

In this paper, the conventional voltage drop compensation methods are reviewed and the novel design and driving scheme, the advanced power de-coupled (aPDC) driving method, is proposed to effectively compensate the voltage IR drop of active matrix light emitting diode (AMOLED) displays. The advanced PDC driving scheme can be applied to general AMOLED pixel circuits that have been developed with only minor modification or without requiring modification in pixel circuit. A 14-in. AMOLED panel with the aPDC driving scheme was fabricated. Long range uniformity (LRU) of the 14-in. AMOLED panel was improved from 43% without the aPDC driving scheme, to over 87% at the same brightness by using the scheme and the layout complexity of the panel with new design scheme is less than that of the panel with the conventional design scheme.
Studies on the poly(vinyl alcohol) degrading enzyme. Part VI. Degradation mechanism of poly(vinyl alcohol) by successive reactions of secondary alcohol oxidase and .BETA.-diketone hydrolase from Pseudomonas sp. (1986)

The secondary alcohol oxidase from Pseudomonas sp. catalyzed the oxidation of various vinyl alcohol oligomers with the molecular weight of 220 to 1500 and of β-ketols such as 5-hydroxy-3-heptanone, 4-hydroxy-2-nonanone, 3-hydroxy-5-nonanone, 6-hydroxy-4-nonanone, 7-hydroxy-5-dodecanone, and 8-hydroxy-6-tridecanone. β-Diketone hydrolase from the same strain catalyzed the hydrolysis of various aliphatic β-diketones and some aromatic β-diketones such as l-phenyl-1, 3-butanedione and 1-phenyl-2, 4-pentanedione. 4, 6-Nonanediol, used as a low molecular weight model of poly(vinyl alcohol) (PVA), was oxidized to 4, 6-nonanedione by way of 6-hydroxy-4-nonanone by secondary alcohol oxidase. 4, 6-Nonanedione was hydrolyzed to 2-pentanone and nbutyric acid by β-diketone hydrolase. These reactions were stoichiometric. The presence of the β-diketone structure in PVA oxidized by secondary alcohol oxidase was confirmed by spectral experiments. The absorption due to β-diketone structure in the oxidized PVA decreased as it was hydrolyzed by β-diketone hydrolase. The ratio of the amount of carboxyl groups in the degraded PVA to that of carbonyl groups in the oxidized PVA became more than 0.5. A pathway for the enzymatic degradation of PVA was proposed.
Social and emotional components of book reading between caregivers and their toddlers in a high-risk sample (2011)

In this collective case study of caregiver behaviors with their toddlers, two-minute videotaped reading interactions were analyzed using a constant comparative method. Twenty-four caregiver—toddler dyads from a high-risk sample of children prenatally exposed to cocaine were selected from a larger sample because they represented the extremes of expressive language scores on the Reynell Expressive Language Quotient at 36 months, one year after the reading interactions. Caregivers in the high-scoring group shared control of the book and discourse, were ‘in tune’ with the child’s needs and abilities, and answered their own questions to the children. This was in contrast to the behaviors of caregivers of the low-scoring children, who appeared unaware of the child’s developmental needs in the interaction, particularly in their ability to respond to the questions posed. Implications of the results for future research on caregiver reading with young children are discussed.
Improvements to the analysis-by-synthesis loop in CELP codecs (1995)

In this paper extensions to the analysis-by-synthesis (AbS) loop used in code excited linear predictive (CELP) speech codecs are considered. Methods for updating the short-term synthesis filter once the excitation parameters have been determined are examined. We show that significant improvements can be achieved by updating the synthesis filter, similar to those obtained using the well known methods of interpolation and bandwidth expansion. However our proposed method of update avoids the increase in the delay of a codec that is usually associated with interpolation. Furthermore the traditional sequential method of determining the adaptive and fixed codebook parameters is examined and compared to an exhaustive search of both codebooks. Three sub-optimum techniques are proposed for improving the performance of the codebook search while maintaining a reasonable level of complexity. The most complex of these increases the codec complexity by only about 40% but provides 80% of the maximum possible 1.1 dB segmental SNR improvement associated with an exhaustive codebook search.

Photosensitizing Metal–Organic Framework Enabling Visible-Light-Driven Proton Reduction by a Wells–Dawson-Type Polyoxometalate (2015)

A simple and effective charge-assisted self-assembly process was developed to encapsulate a noble-metal-free polyoxometalate (POM) inside a porous and phosphorescent metal-organic framework (MOF) built from [Ru(bpy)3](2+)-derived dicarboxylate ligands and Zr6(μ3-O)4(μ3-OH)4 secondary building units. Hierarchical organization of photosensitizing and catalytic proton reduction components in such a POM@MOF assembly enables fast multielectron injection from the photoactive framework to the encapsulated redox-active POMs upon photoexcitation, leading to efficient visible-light-driven hydrogen production. Such a modular and tunable synthetic strategy should be applicable to the design of other multifunctional MOF materials with potential in many applications.
Nuclear matrix association of the human  -globin locus utilizing a novel approach to quantitative real-time PCR (2003)

The human beta-globin locus is home to five genes that are regulated in a tissue-specific and developmental stage-specific manner. While the exact mode of expression remains somewhat enigmatic, a significant effort has been focused at the locus control region (LCR). The LCR is marked by five DNase I-hypersensitive sites (HS) approximately 15 kb upstream of the epsilon-globin gene. Nuclear matrix-associated regions (MARs) organize chromatin into functional domains and at least one of the HS appears bound to the nuclear matrix. We have employed an in vivo based PCR MAR assay to investigate the role of MAR-mediated regulation of the beta-globin locus. This was facilitated with a novel reaction efficiency based quantitative real-time PCR analysis software tool, Target Analysis Quantification. Using a log-linear regression strategy, discordances were eliminated. This allowed us to reliably estimate the relative amount of initial template associated with the nuclear matrix at 15 unique regions spanning the beta-globin locus in both non-expressing and expressing cell lines. A dynamic association dependent on expression status was revealed both at the LCR/5'HS region and within the second intron of the beta-globin gene. These results provide the first evidence that nuclear matrix association dynamically mediates the looping of the beta-globin locus to achieve transcriptional control.
Design of a Highly Directional Endfire Loudspeaker Array (2009)

The applicability of a loudspeaker line array, of which the main directivity is in the length direction of the array, is discussed. Hence this acoustic array aims at the endfire beamforming direction, resulting in a spotlight of sound in a preferred direction. Optimized beamforming techniques are employed, which have been developed earlier for the reciprocal problem of directional microphone arrays. Effects of the design parameters of the loudspeaker array system on its performance have been investigated. It is shown that the stability factor of the optimized beamformer can be a useful parameter to control the directional characteristics of the array. In addition the effect of mutual interaction between individual loudspeaker elements in the array system has been considered to reduce the difference between designed and actual performance of the array system. A prototype constant-beamwidth array system has been tested by simulation and measurement and the results support findings in a parametric analysis.
A low-distortion 22 kHz 5th-order Bessel filter (1993)

A low-distortion MOSFET-C filter design is proposed. The proposed technique relies on the linearity of the passive resistors and the tunability of current-steering MOS transistors operating in the triode region. Placing the nonlinear elements inside the feedback loops and degenerating the MOSFETs by passive resistors, greatly reduces the distortion resulting from the nonlinear devices. A prototype 22-kHz Bessel filter automatically tuned to a switched-capacitor reference resistor has control voltage feedthrough below -100 dB, and measured linearity better than -90-dB THD (total harmonic distortion), with a 2-kHz, 4-V/sub pp/ voltage swing. Measured THD demonstrates an improvement of at least 30 dB over a conventional MOSFETC filter. The chip consumes 40 mW with a 5-V supply, and the active die area is 7 mm/sup 2/ in 2- mu m double-poly CMOS.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synerazol, a new antifungal antibiotic. (1991)

Synerazol, a new antifungal antibiotic, was isolated from cultured broth of Aspergillus fumigatus SANK 10588. The structure was determined based on NMR and mass spectral evidences. Synerazol was found to be a related substance to pseurotin A. Synerazol was active against Candida albicans and other fungi, and showed marked synergistic activity with azole-type antifungal agents.
Autoradiographic differentiation of mu, delta and kappa opioid receptors in the rat forebrain and midbrain (1988)

While there is an abundance of pharmacological and biochemical evidence to suggest the existence of multiple opioid receptors, their precise localization within the brain is unclear. To help clarify this issue, the present study examined the distributions of the mu, delta, and kappa opioid receptor subtypes in the rat forebrain and midbrain using in vitro autoradiography. Mu and delta receptors were labeled with the selective ligands 3H-DAGO (Tyr- D-Ala-Gly-MePhe-Gly-ol), and 3H-DPDPE (D-Pen2, D-Pen5-enkephalin), respectively, while the kappa receptors were labeled with 3H-(-)bremazocine in the presence of unlabeled DAGO and DPDPE. Based on previous findings in our laboratory, the labeling conditions were such that each ligand selectively occupied approximately 75% of each of the opioid sites. The results demonstrated that all 3 opioid receptor subtypes were differentially distributed in the rat brain. Mu binding was dense in anterior cingulate cortex, neocortex, amygdala, hippocampus, ventral dentate gyrus, presubiculum, nucleus accumbens, caudate putamen, thalamus, habenula, interpeduncular nucleus, pars compacta of the substantia nigra, superior and inferior colliculi, and raphe nuclei. In contrast, delta binding was restricted to only a few brain areas, including anterior cingulate cortex, neocortex, amygdala, olfactory tubercle, nucleus accumbens, and caudate putamen. Kappa binding, while not as widespread as observed with mu binding, was densely distributed in the amygdala, olfactory tubercle, nucleus accumbens, caudate putamen, medial preoptic area, hypothalamus, median eminence, periventricular thalamus, and interpeduncular nucleus. While all 3 opioid receptor subtypes could sometimes be localized within the same brain area, their precise distribution within the region often varied widely. For example, in the caudate putamen, mu binding had a patchy distribution, while delta and kappa sites were diffusely distributed, with delta sites being particularly dense ventrolaterally and kappa sites being concentrated ventromedially. These results support the existence of at least 3 distinct opioid receptors with possibly separate functional roles.
