Yan Xu and co-workers report on p. 3017 on a phospholipid polymer hydrogel that exhibits a remarkable ability to preserve cells on microfluidic chips without perfusion culture under cell-based assay conditions, with characteristics including maintenance of high cell viability, restraint of cell proliferation, and minimization of cellular function loss over a period of days and weeks. This material could establish a revolutionary flexibility for cellbased applications.
Design and Implementation of IEEE 1900.4 Architecture Using IMS Functionality (2012)

We propose a new cognitive radio network architecture using the IP multimedia subsystem (IMS) functionality. We implement the cognitive radio network entities standardized in IEEE 1900.4 on the IMS that exchanges RAN and terminal context information between the networks and the terminals to make optimum and immediate reconfiguration decisions. In our proposed architecture, RAN context information is obtained from cellular networks which are directly connected to the IMS. The presence management functions of the IMS are applied to exchange those information in a “push” manner, which enables immediate notification of changes in wireless environment. We evaluate the performance of the proposed context information exchange method, by comparing with the cases that adequate and immediate RAN context information is not available. The evaluation results show that the proposed framework gives 10-30% superior performance than the conventional cognitive radio networks.

Distance Dependent Depth Filtering in 3D Warping for 3DTV (2007)

Depth image-based rendering (DIBR) is the process of synthesizing some new "virtual" views from one "real" view and the associated per-pixel depth information. The most important problem in this process is to deal with the newly exposed areas (holes) appearing in the virtual images. One common solution to decrease the number of holes is to pre-process the depth map, before the warping. In this paper, we present a new filtering technique for depth image-based rendering. In order to reduce or completely remove the newly exposed areas an efficient smoothing is necessary for the sharp depth changes near object boundaries. In the meantime it is useless to filter the smooth areas in the depth map. Our solution is based on a weighted Gaussian filter taking into account the distance to the contours. By this way, the geometric distortions and the computation time are reduced compared to a uniform filtering of the depth map. We present some results in the context of creation of stereoscopic views for 3D TV.
Self-clearing dielectric elastomer actuators using charcoal-powder electrodes (2012)

This study found that compliant electrodes using charcoal powder enable self clearing property to dielectric elastomer actuator. Charcoal powder is applied as compliant electrodes by smearing on a 100% bi-axially pre-stretched dielectric elastomer membrane (VHB 9473), with nominal pre-stretched thickness of 62.3 μm. This DEA using charcoal-powder electrodes can sustain up 10 kV without terminal breakdown, while those using graphite or silver grease break down at slightly above 2 kV. It is noted that this DEA using charcoal-powder has maximum areal strain at about 45 % at 4 kV, beyond which the strain does not increase further for reduced electrical conductivity. The dielectric elastomer actuator using the charcoal-powder electrodes generate less actuation strain than that using the graphite. However, the former can produce a large actuation stress as it can driven to a higher driving voltage without pre-mature breakdown.
Continuous Administration of a P450 Aromatase Inhibitor Induces Polycystic Ovary Syndrome with a Metabolic and Endocrine Phenotype in Female Rats at Adult Age (2012)

Studying the mechanisms for the complex pathogenesis of polycystic ovary syndrome (PCOS) requires animal models with endocrine, reproductive, and metabolic features of the syndrome. Hyperandrogenism seems to be a central factor in PCOS, leading to anovulation and insulin resistance. In female rats, continuous administration of letrozole, a nonsteroidal inhibitor of P450 aromatase, at 400 μg/d starting before puberty induces hyperandrogenemia and reproductive abnormalities similar to those in women with PCOS. However, despite high circulating testosterone levels, these rats do not develop metabolic abnormalities, perhaps because of their supraphysiological testosterone concentrations or because estrogen synthesis is completely blocked in insulin-sensitive tissues. To test the hypothesis that continuous administration of lower doses of letrozole starting before puberty would result in both metabolic and reproductive phenotypes of PCOS, we performed a 12-wk dose-response study. At 21 d of age, 46 female Wistar rats were divided into two letrozole groups (100 or 200 μg/d) and a control group (placebo). Both letrozole doses resulted in increased body weight, inguinal fat accumulation, anovulation, larger ovaries with follicular atresia and multiples cysts, endogenous hyperandrogemia, and lower estrogen levels. Moreover, rats that received 200 μg/d had insulin resistance and enlarged adipocytes in inguinal and mesenteric fat depots, increased circulating levels of LH, decreased levels of FSH, and increased ovarian expression of Cyp17a1 mRNA. Thus, continuous administration of letrozole, 200 μg/d, to female rats for 90 d starting before puberty results in a PCOS model with reproductive and metabolic features of the syndrome.
ACTIVITY OF ADENOSINE DEAMINASE AND ITS ISOENZYMES IN SERUM OF PREGNANT BUFFALOES (2007)

Adenosine deaminase (ADA), an enzyme involved in purine catabolism, exists in two main isoenzymes forms, ADA1 and ADA2 which have different optimal pH, Michael’s constant and relative substrate specificity. Monocyte macrophages produce and release ADA2 when they are stimulated by infection (Gakis et al., 1995; Alrokayan, 2002) or when immunity is altered (Gakis, 1996). Pregnancy is associated with depressed cell mediated immunity (Gakis, 1996). Blood samples were obtained 6 hours post feeding from juggler vein of 66 pregnant and 13 non pregnant buffaloes. Serum was separated and used for the measurement of concentrations of ADA, ADA1 and ADA2. Activity of the ADA enzyme was measured spectrophotometrically

Magnetic resonance current density image reconstruction in the spatial frequency domain (2003)

The purpose of this study is to improve noise immunity of electrical current density image reconstruction in magnetic resonance current density imaging (MRCDI) and magnetic resonance electrical impedance tomography (MREIT). In the MRCDI and MREIT techniques, electrical current densities have been calculated by taking curls to the extra magnetic fields generated by externally applied electrical currents. The extra magnetic fields are calculated from the phase information in magnetic resonance images. Both the phase calculations and curl operations are very sensitive to the noise. Since the curl operation in the space domain appears as a high pass filter in the spatial frequency domain and the current density images have very little high frequency components, we can adopt various kinds of spatial filtering techniques during the curl operation to improve the signal-to-noise ratio of the current density images. We have compared current density estimation results between the proposed and conventional methods for several kinds of current distribution patterns. For the current distributions with little high spatial frequency components, the proposed current density reconstruction method has been found to be superior to the conventional method.
Linear Dropout Regulator based power distribution design under worst loading (2011)

This paper introduces a methodology to design and to optimize power distribution with on-die Linear Dropout Regulators (LDO). An analytical formula for worst voltage drop is derived that takes into account LDO-PDN system poles and zeros. LDO power and decoupling capacitor optimization flow is proposed to meet the system voltage noise requirements.
Critical study of integral methods in compressible laminar boundary layers (1952)

A number of the most promising inte~sl methods for solving approximately the compressible-lamlnar-boundary -l~er equations are investigated in order to determine a computationdly convenient and sufficiently accurate method of calculating boundary-lsyer ~a~teri stics.The chief methods considered sre: (a) The one-parameter Karman-Pohlhausen method, with three different assumptions for the velocity profiles, and (b) the two-parameter method, first applied by Sutton, with two different assumptions for the velocity profiles.After the methods are explicitly described in general terms for the case of zero pressure gradient and for the case of a pressure gradient in the direction of flow with zero heat transfer, they are applied to the calculation of the compressible laminar boundary layer over a surface with zero pressure gradient, with and without heat transfer at the surface, for the purpose of establishing the accuracy of the methods.Comparison of the results is made with those of known exact solutions for skin-friction and heat-transfer coefficients, velocity profiles, velocity derivatives, and especially layer stability.. From this comparison it is found that Pohlhausen method with a sixth-degree polynomial as the is the most suitable for many practical purposes.. . .
Magneto-Optical Fe/Tb/Nd/Tb Multilayers: Anisotropy and Kerr Rotation (1998)

To increase the recording density of magneto-optic materials, they have to fulfill some special features: High coercivity Hc, Curie-temperature T c between 100 and 200°C, measurable Kerr rotation θ K at low wavelengths, perpendicular magnetic anisotropy and rectangular shaped magnetization loops. For the commercial magneto-optical applications FeTbCo-alloys are used. This conventional material does not suffice the requirements of high density storage media at the wavelength of blue laser beam. For this propose the idea was born to combine Fe/Tb-multilayers with the light rare-earth metal neodymium to increase the Kerr rotation [2]. To study the magnetic properties of such systems, different multilayer setups, including the elements iron, terbium and neodymium, were sputter deposited. These multilayers were analyzed magnetically with a vibrating sample- (VSM), a torque magnetometer (TOM) and with a polar magneto-optical Kerr-effect-instrument (PMOKE), respectively a Kerr-spectrometer to find the best layer combination for fulfilling the above named features.

Characterization of cellulose extracted from oil palm empty fruit bunch (2015)

Recently, cellulose has been studied by many researchers due to its promising properties such as biodegradability, biocompatibility, hydrophilicity and robustness. Due to that it is applied in many fields such as paper, film, drug delivery, membranes, etc. Cellulose can be extracted from various plants while oil palm empty fruit bunch (OPEFB) is the one of its sources. In this study, cellulose was extracted by chemical treatments which involved the use of formic acid and hydrogen peroxide to remove hemicellulose and lignin components. Maximum yield was 43.22%. Based on the FT-IR spectra, the peak of wax (1735 cm−1), hemicellulose (1375 cm−1) and lignin (1248 cm−1 and 1037 cm−1) were not observed in extracted cellulose. TGA analysis showed that the extracted cellulose starts to thermally degrade at 340 °C. The SEM analysis suggested that the cellulose extracted from OPEFB was not much different from commercial cellulose.
CD38 Bright Effector Memory CD8+ T Cell Populations Predict Acute Graft Versus Host Disease (2013)

Acute graft versus host disease (aGVHD) is mediated by allogeneic T cell responses. We hypothesized that peripheral blood expansion of activated effector memory T cell populations (TEM) following allogeneic hematopoietic cell transplantation (HCT) would serve as a useful predictor of aGVHD.
TweetCount (2017)

This paper characterizes an urban region using time series of geotagged tweet counts. Time series are constructed for each cell in a rectangular grid. We show how simple, anonymous tweet counts in the cells can be used to classify the cells into urban land use profiles based on the number of residences and businesses. We discover that Twitter activity for a certain short time of day is especially indicative of a region's profile. We go on to analyze the cells and profiles in a novel way by looking at their ability to predict tweet counts in other parts of the region.
A novel protein phosphatase 2C family member (PP2Cζ) is able to associate with ubiquitin conjugating enzyme 9<sup>1</sup> (2003)

In this study we have cloned a novel member of mouse protein phosphatase 2C family, PP2Czeta, which is composed of 507 amino acids and has a unique N-terminal region. The overall similarity of the amino acid sequence between PP2Czeta and PP2Calpha was 22%. On Northern blot analysis PP2Czeta was found to be expressed specifically in the testicular germ cells. PP2Czeta expressed in COS7 cells was able to associate with ubiquitin conjugating enzyme 9 (UBC9) and the association was enhanced by co-expression of small ubiquitin-related modifier-1 (SUMO-1), suggesting that PP2Czeta exhibits its specific role through its SUMO-induced recruitment to UBC9.
The outcome of patients with advanced hepatocellular carcinoma (HCC) in pre- and post-sorafenib eras using the SEER database. (2013)

276 Background: HCC is the third most common cause of cancer-related death globally. Prognosis for advanced HCC is dismal due to lack of effective treatment options for the majority of patients who present with advanced disease. Sorafenib was the first agent reported to improve overall survival in patients with good liver function enrolled in phase III clinical trials. However, survival impact of sorafenib on the general population with advanced HCC has not been studied to date. Methods: Sorafenib was approved for patients with advanced HCC and Child-Pugh A liver disease in 2007. We analyzed 2005-2006 and 2008-2009 clinical outcome data from the SEER to compare the impact of this targeted therapy in the population based setting. The Kaplan-Meier method was used to estimate the median survival and 95% confidence intervals (CI). The log-rank test was used to test the difference in survival curves. Cox regression analyses were utilized for the estimation of hazard ratios. Results: We identified 2297 and 2808 stage III and IV HCC cases diagnosed in [2005, 2006] and [2008, 2009], respectively. Seventy-seven percent of the patients were male and the median age was 61 years old for males and 66 for females. The median survival estimates (95% CIs) are 3 (3, 4) months and 4 (4, 4) months for patients diagnosed in [2005, 2006] and [2008, 2009], respectively. The hazard ratio (95% CI) for overall survival comparing [2008, 2009] to [2005, 2006] was 0.92 (0.87, 0.98, p-value = 0.01). We performed multivariable Cox regression modeling and African American patients have a hazard ratio of death [1.14 (1.06, 1.23)] as compared to European American patients. Younger females have a decreased hazard of dying relative to younger men, while older females have an increase hazard of dying relative to older men. Conclusions: The approval of sorafenib treatment produced very modest median survival gain in advanced HCC patients based on SEER population study. However, the small benefit in hazard ratio may have been impacted by small number of patients with advanced HCC who are being treated or are able to be treated with sorafenib in this era.

Online power quality disturbances identification using incremental wavelet decomposition and support vector machine (2008)

Power quality disturbances identification is the important procedure for improving power quality, and online application has actual value. An efficient method for power quality disturbances identification is presented in this paper. Wavelet decomposition is used for extracting the features of various disturbances, and support vector machine in data mining is used for classifying the disturbances. For online application, sliding window model and incremental algorithms for wavelet decompositions are used. This method has low cost in memory and run time, it can identify different disturbances in high accuracy and less time. Simulation experiment using several typical disturbances, swell, sag, interrupt, harmonic, transient impulse, transient oscillation, is finished, and a primary experiment using data from real power system is implemented, the experimental results show effectiveness of proposed method.
Differences in weight status and energy-balance related behaviors among schoolchildren in German-speaking Switzerland compared to seven countries in Europe (2012)

The prevalence of overweight and obesity among Swiss children are substantial but significantly lower compared to all other European ENERGY-Partners, probably due to the fact that Swiss children were found to be more active and less sedentary comparing to the rest of the European sample.
<title>Time-of-flight mass spectrometry of DNA laser-ablated from frozen aqueous solutions: applications to the Human Genome Project</title> (1993)

Techniques have been developed to volatilize intact massive DNA molecules using pulsed laser ablation of thin frozen films of aqueous DNA solutions. Electrophoresis assay of the ablated DNA shows that molecules as massive as approximately 400,000 Da can be ablated intact. It has been possible to obtain time-of-flight mass spectra of ablated multicomponent mixtures of single-stranded DNA with masses up to approximately 18,000 Da (a 60-nucleotide DNA oligomer). The possible application of time-of-flight mass spectrometry to the analysis and readout of DNA sequence mixtures, and the potential thereby to accelerate the Human Genome project, are discussed.
Registration of Arblick and Ecoturf Rhizoma Peanut Germplasms for Ornamental or Forage Use (2010)

Arblick (Reg. No. GP‐128; PI 658528) and Ecoturf (Reg. No. GP‐129; PI 658529) are rhizoma peanut (RP) ( Arachis glabrata Benth.) germplasms released by the Univ. of Florida in 2008. These plant introductions were identified as lower growing “ground cover” type plants. These lines are being released as germplasm to document the dual purpose ornamental and forage characteristics of the lines. Arblick was collected near the town of Bela Vista, Brazil, located on the border of Brazil and Paraguay. It has green group leaves (RHS 137B), with an orange group standard petal (RHS 24A and a yellow orange group wing petal (RHS 14B). Arblick generally is somewhat slower to establish than other forage type cultivars, has limited forage potential, and has not been widely planted. Ecoturf was collected along the Brazil–Paraguay border on the same collection expedition as Arblick, not far from where Arblick was collected. Flower color of Ecoturf is similar to Arblick, but it has yellow green group leaves (RHS 144A). Arblick and Ecoturf are lower growing types that flower profusely during the growing season. Ecoturf has gained acceptance by the commercial landscape industry for use as an ornamental ground cover. These germplasms will benefit specialty users of “ornamental” types of RP but also because of their dual‐use potential will diversify the RP plantings to avoid the near monoculture of ‘Florigraze’
The actions of N-propyl ajmaline on experimental arrhythmias and electrophysiological properties of the heart. (1974)

The antiarrhythmic and general cardiovascular effects and acute toxicity of N-propyl ajmaline (NPA) and ajmaline (AJM) were studied in the dog, rabbit and mouse. NPA was approximately three to seven times more potent than AJM. In addition, the antiarrhythmic mechanism was investigated electrophysiologically on the isolated guinea pig atria and on the isolated dog ventricular muscle, right bundle branch and Purkinje fibres. Both drugs caused a decrease in the spontaneous beating rate of the atria, a prolongation of the refractory period and a reduction in the conduction velocity in the Purkinje fibres. The results of the study suggest that the actions of both drugs do not substantially differ, although they have quantitative differences.
Cover Picture: The Activation of Fibroblast Growth Factors (FGFs) by Glycosaminoglycans: Influence of the Sulfation Pattern on the Biological Activity of FGF‐1 (ChemBioChem 1/2004) (2003)

The cover picture shows a comparison of the effect of increasing concentrations of heparin and two synthetic heparin‐like hexasaccharides, with specifically designed different sulfation patterns, on the mitogenic activity of acidic fibroblast growth factor (FGF‐1). These two hexasaccharides, members of a series of six synthetic oligosaccharides with the same monosaccharide sequence but differing size and charge distribution, either have different negative charge orientations on both sides, like heparin itself, or on one side of their three dimensional helical structures. This alternative arrangement induces differences in the electrostatic potential, as is shown in the surface maps. The hexasaccharide with sulfate groups on only one side of the helix stimulates FGF‐1 more efficiently than that with the sulfate groups distributed on both sides as in the regular region of heparin. This result and the fact that, according to sedimentation‐equilibrium analysis, these oligosaccharides do not promote FGF‐1 dimerization, strongly suggest that FGF oligomerization is not a general and absolute requirement for biological activity. Further details can be found in the article by M. Martín‐Lomas and co‐workers on p. 55 ff.
Characteristics and Viral Susceptibility of an Embryo Cell Line from Marmosa mitis (1972)

A cell line designated as MME, was established from the embryo of a pouch-less South American marsupial, Marmosa mitis. The cells were mostly fibroblastic in shape and displayed contact inhibition. Cytogenic evaluation revealed a simple karyotype (2n = 14) and large chromosomes. Growth curves of MME cells at passages 22 and 31 showed a relatively short doubling time of 20 hr. The MME cells had a fairly wide viral spectrum. Vesicular stomatitis, influenza A, infectious bovine rhinotracheitis, myxoma and bluetongue viruses were all capable of replication in this cell line.
