Effect of resistance training on lumbar extension strength (1989)

Development of a new testing machine, which stabilizes the pelvis, allowed us to evaluate the lumbar extensor muscles before and after training. Fifteen healthy subjects (29.1 +/- 8 years of age) trained 1 day per week for 10 weeks and 10 healthy subjects (33.7 +/- 16 years of age) acted as controls. Training consisted of 6 to 15 repetitions of full range of motion variable resistance lumbar extension exercise to volitional fatigue and periodic maximal isometric contractions taken at seven angles through a full range of motion. Before and after the 10 week training period, subjects completed a maximum isometric strength test at seven angles through a 72 degrees range of motion (0 degrees, 12 degrees, 24 degrees, 36 degrees, 48 degrees, 60 degrees, and 72 degrees of lumbar flexion). The training group significantly improved in lumbar extension strength at all angles (P less than or equal to 0.01). The result at 0 degrees (full extension) showed an increase from 180.0 +/- 25 Nm to 364.1 +/- 43 Nm (+102%) and at 72 degrees (full flexion) from 427.4 +/- 44.1 to 607.4 +/- 68 (+42%) Nm. Results from the control group showed no change (P greater than or equal to 0.05). The magnitude of gain shown by the training group reflects the low initial trained state of the lumbar extensor muscles. These data indicate that when the lumbar area is isolated through pelvic stabilization, the isolated lumbar extensor muscles show an abnormally large potential for strength increase.
Bandwidth Enhancement Technique for Broadside Tri-Modal Patch Antenna (2020)

A technique for enhancing the bandwidth of a broadside tri-modal patch antenna is described. The key idea of the technique is to incorporate a dual-resonance structure into the broadside tri-modal patch geometry. By increasing one edge of the tri-modal patch while decreasing its size at the opposite edge, the resulting structure can be viewed as two superimposed Y-shaped structures of different resonant frequencies. This intuition is confirmed using characteristic mode analysis (CMA). Furthermore, guided by CMA, further modifications enable two sets of resonant modes to be tuned for increasing the bandwidth of the tri-modal patch antenna. Importantly, the proposed bandwidth enhancement technique does not affect the desired broadside radiation patterns significantly. Therefore, it can be utilized to modify the tri-modal patch antenna without degrading its potential for massive MIMO array application. Measurement results show that the technique enhances the 10 dB impedance bandwidth from 4.3% to 19.7% with the largest antenna dimension of $0.48{\lambda _{c}}$ , where ${\lambda _{c}}$ is the wavelength in air at the center frequency. The design example of the proposed technique is able to cover widely used 3 GHz bands in 5G communication systems and its potential usage in massive MIMO arrays is demonstrated.
Mapping of chromosomal imbalances in gastric adenocarcinoma revealed amplified protooncogenes <i>MYCN</i> , <i>MET</i> , <i>WNT2</i> , and <i>ERBB2</i> (1998)

Gastric adenocarcinoma is a malignant tumor with a high incidence and a low survival rate. In order to identify genetic alterations associated with this tumor, we screened 23 gastric adenocarcinomas for recurrent chromosomal imbalances by using comparative genomic hybridization (CGH). The most common gains of chromosomal material were found on chromosome arms 20q (10 cases), 16p (7 cases), and 1q (4 cases) and on chromosome 11 (4 cases). Losses were observed on chromosome arms 4q, 5q, 9p, and 21q (3 cases each). Four tumors exhibited high-level amplifications localized on chromosome regions 2p23-p24, 7q31-q32, 8p21-p22, 10q25-q26, 11q13, 17q11-q21, and 20q. Based on the position of these amplifications, candidate (onco)genes were selected and subsequently tested by Southern blot analysis of the respective tumors. Of the seven tested candidates, MYCN, MET, WNT2, and ERBB2 were found to participate in the amplicons of the respective tumor samples. Of these four presumably activated oncogenes, two, MYCN and WNT2, were previously not assumed to play a pathogenic role in stomach cancer. Among the other regions of imbalance, gain of 20q seems particularly interesting, because it is found in almost half of the analyzed cases and is highly amplified. Our data allowed us to narrow the relevant region down to the commonly gained bands 20q12-q13.1. This and other imbalanced regions provide a basis for searching new putative oncogenes and tumor suppressor genes involved in the development or progression of gastric adenocarcinoma.
Functional Remineralization of Dentin Lesions Using Polymer-Induced Liquid-Precursor Process (2012)

It was hypothesized that applying the polymer-induced liquid-precursor (PILP) system to artificial lesions would result in time-dependent functional remineralization of carious dentin lesions that restores the mechanical properties of demineralized dentin matrix. 140 µm deep artificial caries lesions were remineralized via the PILP process for 7-28 days at 37°C to determine temporal remineralization characteristics. Poly-L-aspartic acid (27 KDa) was used as the polymeric process-directing agent and was added to the remineralization solution at a calcium-to-phosphate ratio of 2.14 (mol/mol). Nanomechanical properties of hydrated artificial lesions had a low reduced elastic modulus (E(R) = 0.2 GPa) region extending about 70 μm into the lesion, with a sloped region to about 140 μm where values reached normal dentin (18-20 GPa). After 7 days specimens recovered mechanical properties in the sloped region by 51% compared to the artificial lesion. Between 7-14 days, recovery of the outer portion of the lesion continued to a level of about 10 GPa with 74% improvement. 28 days of PILP mineralization resulted in 91% improvement of E(R) compared to the artificial lesion. These differences were statistically significant as determined from change-point diagrams. Mineral profiles determined by micro x-ray computed tomography were shallower than those determined by nanoindentation, and showed similar changes over time, but full mineral recovery occurred after 14 days in both the outer and sloped portions of the lesion. Scanning electron microscopy and energy dispersive x-ray analysis showed similar morphologies that were distinct from normal dentin with a clear line of demarcation between the outer and sloped portions of the lesion. Transmission electron microscopy and selected area electron diffraction showed that the starting lesions contained some residual mineral in the outer portions, which exhibited poor crystallinity. During remineralization, intrafibrillar mineral increased and crystallinity improved with intrafibrillar mineral exhibiting the orientation found in normal dentin or bone.
Sparse characterization of PPG based on K- SVD for beat-to-beat blood pressure prediction (2018)

Continuous non-invasive monitoring of blood pressure is essential for cardiovascular risk patients. This article presents the sparse characterization of Photoplethysmogram (PPG) using K-SVD technique for beat-to-beat blood pressure estimation. The relative changes in the blood volume that is represented by PPG is influenced by the pressure changes in the peripheral circulation. Owing to the anomalous nature of the time domain features obtained from ECG and PPG, we propose the use of sparse representation as means of feature extraction method. The sparse features generated from K-SVD processed dictionary that can approximate the shape of the PPG signal were taken as the features to predict the BP values. The proposed system is evaluated using the Multi-Parameter Intelligent Monitoring for Intensive Care (MIMIC-II) database. The proposed method is compared with the baseline system that employs time domain features for BP prediction. The Mean Absolute Error (MAE) and Root mean square Error (RMSE) between the predicted BP and ground truth BP were chosen as the performance measures. The system achieved the error measure of (MAE ± RMSE) 5.06 ± 6.27 mmHg for systolic BP and 2.99 ± 3.93 mm Hg for Diastolic BP. Further, the comparison studies suggests that the proposed system outperforms the baseline system with an overall reduction in MAE and RMSE by 20.55% and 22.14% respectively for systolic BP and 28.15% and 23.48% respectively for Diastolic BP. Hence, the sparse representation of PPG can be successfully utilized for the beat-to-beat prediction of BP.
Are Molecular 5,8‐π‐Extended Quinoxaline Derivatives Good Chromophores for Photoluminescence Applications? (2006)

Abstract The synthesis of a new series of photoluminescent compounds, namely 5,8‐diaryl quinoxaline derivatives (aryl = phenyl, 4‐fluorophenyl, 4‐methoxyphenyl, and 4‐cyanophenyl), was achieved by a direct Suzuki cross‐coupling reaction with the employment of a NCP‐pincer palladacycle. The electrochemical and photophysical properties of these compounds were also investigated. Four new 4,8‐diaryl‐2,1,3‐benzothiadiazoles were also synthesized in order to enable a comparison between the two types of nitrogen‐containing π‐extended heterocycles. The substitution of a hydrogen atom at the 4‐position of the aryl that is groups attached to the quinoxaline or benzothiadiazole base by either electron‐donating or ‐withdrawing groups results in an increase in the bandgap energy (from 2.21 to 2.52 eV) of π‐extended 5,8‐quinoxaline derivatives and a decrease in the bandgap energy (from 2.65 to 2.40 eV) of π‐extended 2,1,3‐benzothiadiazoles. Moreover, π‐extension at the 5‐ and 8‐positions of the quinoxaline core is not essential for the photoluminescence of these compounds and 4,7‐π‐extended 2,1,3‐benzothiadiazole derivatives are far better candidates for luminescence applications than are the quinoxaline derivatives.(© Wiley‐VCH Verlag GmbH & Co.

Simplified hand model including the user's forearm for the study of internal GSM/DCS mobile phone antenna (2006)

Abstract A simplified hand model for the study of internal mobile phone antenna for analyzing its impedance and radiation characteristics with the presence of the user's hand is proposed. The antenna in this study is a compact internal antenna having two separate resonant strips capable of generating two wide bandwidths for GSM and DCS operations. For the simplified hand model, it is a one‐layer hand model including the user's forearm with a relative permittivity of 35 and a conductivity of 0.5 S/m. With this simplified hand model, efficient and reliable simulation study of the mobile phone antenna with the user's hand can be obtained. Detailed effects of the user's hand on the impedance and radiation characteristics of the internal mobile phone antenna are analyzed in this study. © 2006 Wiley Periodicals, Inc.

In vitro antifungal activity of hydroxychavicol isolated from Piper betle L (2010)

The antifungal activity exhibited by this compound warrants its use as an antifungal agent particularly for treating topical infections, as well as gargle mouthwash against oral Candida infections.
Primary sequence and heterologous expression of nuclear pore glycoprotein p62. (1990)

The major nuclear pore protein p62 is modified by O-linked N-acetylglucosamine and functions in nuclear transport. We have cloned, sequenced, and expressed the full-length rat p62 cDNA. The rat p62 mRNA is 2,941 nucleotides long and encodes a protein of 525 amino acids containing 30% serine and threonine residues. The amino acid sequence near the amino-terminus contains unique tetrapeptide repeats while the carboxy-terminus consists of a series of predicted alpha-helical regions with hydrophobic heptad repeats. Heterologous expression of rat p62 in African Green Monkey Kidney COS-1 cells and CV-1 cells was detected using a species-specific antipeptide serum. When transiently expressed in COS-1 cells, rat p62 binds wheat germ agglutinin and concentrates at the spindle poles during mitosis. In CV-1 cells cotransfected with rat p62 cDNA and SV40 viral DNA, rat p62 associates with the nuclear membrane without interfering with the nuclear transport of SV40 large T antigen. The ability to express p62 in tissue culture cells will facilitate analysis of the role of this pore protein in nuclear transport.
Herta Müller: Tabubruch als Schreibprinzip (2002)

Unter diesem Thema wird eine Untersuchung angestellt, die das Stichwort "Tabu" als Hinweis nimmt, als Anleitung zum Verständnis von Herta Müllers Texten. Dabei wird Müllers ästhetik vor allem in "ortsgebundener" Hinsicht betrachtet; es sind die ästhetischen Verarbeitungen von alltäglichen Geschehnissen in ihrem Land, aus der Zeit ihrer Kindheit, aus der Erfahrungswelt ihres Dorfes, später ihres Studiums in einer kleinen Stadt in der Gesellschaft des Ceauçescu-Regimes, die im Mittelpunkt stehen.
Synthesis and Analysis of Telechelic Polyisobutylenes for Hydrogen-Bonded Supramolecular Pseudo-Block Copolymers (2004)

New telechelic polyisobutylenes (PIB) with hydrogen-bonding motifs were prepared. Nucleobases such as thymine, uracil, and cytosine as well as chelate-type hydrogen-bonding donor−acceptors were affixed onto the end groups of the PIB. Starting with PIB of defined molecular weight, prepared by living cationic polymerization, hydroxyterminated PIB was generated, which subsequently was transformed into the corresponding chloromethyl ether. Reaction with silylated nucleobases furnished the final nucleobase-telechelic PIB in high yields. The chelate-type PIB was prepared by a sequence of nucleophilic/addition reaction steps adapted to the low solubility of PIB polymers in polar solvents. The structure of the PIB polymers was proven by 1H NMR, 13C NMR, and MALDI−TOF MS analysis proving the complete conversion between the reaction steps in quantitative yields. The pure PIB polymers with specific hydrogen bonding patterns will allow the investigation of supramolecular pseudo-block copolymers.
Analyte-Driven Disassembly and Turn-On Fluorescent Sensing in Competitive Biological Media (2018)

Many indicator displacement assays can detect biological analytes in water, but these often have reduced performance in the presence of an unavoidable component: NaCl. We report here a new self-assembled sensor, DimerDye, that uses a novel photochemical guest-sensing mechanism and that is intrinsically tolerant of cosolutes. We synthetically integrated a dye into a calixarene macrocycle, forming two new merocyanine calixarenes (MCx-1 and MCx-2). Both compounds self-assemble into nonemissive dimers in water. The addition of good guests like trimethyllysine induces a turn-on fluorescence response of MCx-1 due to simultaneous dimer dissociation and formation of an emissive host-guest complex. DimerDyes remain functional in solutions containing the various salts, metal ions, and cofactors that are needed for enzymatic reactions. MCx-1 provides a real-time, turn-on fluorescence signal in response to the lysine methyltransferase reaction of PRDM9.
Electrical Properties of n‐Type (111) Si in Aqueous  K 4Fe (  CN  ) 6 Solution: I. Interface States and Recombination Impedance (1996)

The properties of n‐type (111) Si surfaces in aqueous 0.1 M KCl at pH 9 were studied both in the dark and under illumination. In this solution, oxide passivation of the surface gives rise to a variety of electrically active interface states. Both in the dark and under illumination, interface states interacting with the conduction band are present at an energy of about 0.36 eV below the conduction bandedge, giving rise to a characteristic impedance at potentials close to the flatband potential. Furthermore, interface states which act as recombination centers are observed when the surface is illuminated. The density of recombination centers was found to be a function of the light intensity, ranging from 1 × 1012 to , indicating that these states are related to oxidation intermediates. The rate constant for recombination was determined to be about .

Voltage-matched, two-terminal, GaAs (AlGaAs)/CuInSe/sub 2/ tandem solar cells (2002)

Mechanically stacked tandem solar cells based on GaAs thin-film single-crystal top cells and CuInSe/sub 2/ (CIS) bottom cells were developed to meet the weight and radiation-resistance requirements of advanced spacecraft power systems. Efficiencies over 23% have been demonstrated with these cells in a four-terminal configuration. In order to use the device as a direct replacement for conventional single-junction cells with existing array designs. a two-terminal, voltage-matched tandem cell with 8 cm/sup 2/ area has been designed and fabricated. Tandem cells with efficiencies over 20% have been demonstrated with this design. AlGaAs high-bandgap cells have been demonstrated with efficiency over 17% for future AlGaAs/ClS tandem cells capable of higher end-of-life efficiency. The performance of the two-terminal tandem cells and the AlGaAs high-bandgap cell are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Improving the performance of neural networks in regression tasks using drawering (2017)

The method presented extends a given regression neural network to make its performance improve. The modification affects the learning procedure only, hence the extension may be easily omitted during evaluation without any change in prediction. It means that the modified model may be evaluated as quickly as the original one but tends to perform better. This improvement is possible because the modification gives better expressive power, provides better behaved gradients and works as a regularization. The knowledge gained by the temporarily extended neural network is contained in the parameters shared with the original neural network. The only cost is an increase in learning time.
Beta-Aminoisobutyric Acid as a Novel Regulator of Carbohydrate and Lipid Metabolism (2019)

The prevalence and incidence of metabolic syndrome is reaching pandemic proportions worldwide, thus warranting an intensive search for novel preventive and treatment strategies. Recent studies have identified a number of soluble factors secreted by adipocytes and myocytes (adipo-/myokines), which link sedentary life style, abdominal obesity, and impairments in carbohydrate and lipid metabolism. In this review, we discuss the metabolic roles of the recently discovered myokine β-aminoisobutyric acid (BAIBA), which is produced by skeletal muscle during physical activity. In addition to physical activity, the circulating levels of BAIBA are controlled by the mitochondrial enzyme alanine: glyoxylate aminotransferase 2 (AGXT2), which is primarily expressed in the liver and kidneys. Recent studies have shown that BAIBA can protect from diet-induced obesity in animal models. It induces transition of white adipose tissue to a "beige" phenotype, which induces fatty acids oxidation and increases insulin sensitivity. While the exact mechanisms of BAIBA-induced metabolic effects are still not well understood, we discuss some of the proposed pathways. The reviewed data provide new insights into the connection between physical activity and energy metabolism and suggest that BAIBA might be a potential novel drug for treatment of the metabolic syndrome and its cardiovascular complications.
The Settler Evolution: Space, Place and Memory in Early Colonial Australia (2013)

Ideas and expectations about colonial space and the making and remaking of real places lie at the heart of the early Australian colonies. Over the past forty years, and especially in the last decade, scholars have recovered much of that lost world, a world of polyglot diversity, constant movement, economic social and cultural expansion, cross-cultural encounters, relationships and appropriations, extraordinary adaptations, myriad connections and overlaid human geographies. \nYet in the later nineteenth century, the colonies were also profoundly shaped by discontinuities in memory, place and experience, as wave upon wave of new arrivals started new lives literally unaware of what had happened earlier, or how these places had come to be. The success of later settlers was built upon those earlier foundations, and yet false assumptions about ‘gaol colonies’ and ‘savages’, twinned with assertions of legitimate occupancy and entitlement, easily captured the narrative as well as the literal ground, and are still widespread in Australian historiography, popular history and heritage today.
Gamba Grass - an Aggressive Threat to the Environment via Transport Corridors (2000)

Gamba grass (Andropogon gayanus) is a major pest species in the Top End of the Northern Territory. It is a large tussock forming grass (up to 70 cm in diameter and 4 m tall) that forms a dense monoculture. Gamba grass is relatively drought resistant and will flourish in areas with an annual rainfall of greater than 600 mm falling predominantly in summer. The greatest concern to the environment is Gamba grass's characteristics of late curing and very high fuel loads (> 20 t/ha) that lead to very intense, destructive late dry season fires. Gamba grass spreads rapidly along roadsides into disturbed areas before spreading into native grasslands and savannas where it aggressively replaces native grasses and destroys native tree regeneration. This paper describes the methodology we implemented, the results of our program to date, and the future program we intend to implement. The program has been extremely successful and will be of interest to land managers and those responsible for transport corridors in North Queensland where Gamba grass infestations have recently been found.
Local Non-Linear Free Surface Effects for Hull Generating Elementary Waves (1979)

The local non-linear free surface effects acting upon hull generating elementary waves are surveyed. Through the simplification of the exact free surface condition, the basis of the non-linear theory, the low speed theory and the linear theory is characterized.A non-linear wave theory developed as an extension of the geometrical optics is presented. The propagation of elementary waves generated on the hull from bow through stern is numerically traced. The non-linear effects integrated along the passage of waves in the non-uniform double body flow are discussed.Based upon the asymptotical expression for free waves far rear the ship where the remained non-linear effects are taken into account, wave resistance is evaluated for an Inuid model. Less prominent humps and hollows of the calculated wave resistance coincide fairly well with the towing test results within the moderate Froude numbers.
Capsule deletion via a λ-Red knockout system perturbs biofilm formation and fimbriae expression in Klebsiella pneumoniae MGH 78578 (2014)

These results are expected to provide insight into the interaction between capsule biosynthesis, biofilm formation, and fimbriae expression in this organism.
Organization of the Human GLUT2 (Pancreatic β-Cell and Hepatocyte) Glucose Transporter Gene (1993)

The gene encoding the predominant facilitative glucose transporter expressed in pancreatic beta-cells and hepatocytes, termed GLUT2, has been cloned and characterized. The human GLUT2 gene is composed of 11 exons spanning approximately 30 kilobases. The sequence of the promoter region and all exons and adjacent intron regions has been determined and deposited in the GenBank database. Two highly polymorphic simple tandem repeat DNA polymorphisms useful for linkage studies were localized in introns 1 and 4a. In addition, a 168-base pair insertion/deletion polymorphism was identified in intron 3. The characterization of the human GLUT2 gene will facilitate studies of its role in the development of diabetes mellitus.
