MediaRank: Computational Ranking of Online News Sources (2019)

In the recent political climate, the topic of news quality has drawn attention both from the public and the academic communities. The growing distrust of traditional news media makes it harder to find a common base of accepted truth. In this work, we design and build MediaRank (www.media-rank.com), a fully automated system to rank over 50,000 online news sources around the world. MediaRank collects and analyzes one million news webpages and two million related tweets everyday. We base our algorithmic analysis on four properties journalists have established to be associated with reporting quality: peer reputation, reporting bias / breadth, bottomline financial pressure, and popularity. Our major contributions of this paper include: (i) Open, interpretable quality rankings for over 50,000 of the world's major news sources. Our rankings are validated against 35 published news rankings, including French, German, Russian, and Spanish language sources. MediaRank scores correlate positively with 34 of 35 of these expert rankings. (ii) New computational methods for measuring influence and bottomline pressure. To the best of our knowledge, we are the first to study the large-scale news reporting citation graph in-depth. We also propose new ways to measure the aggressiveness of advertisements and identify social bots, establishing a connection between both types of bad behavior. (iii) Analyzing the effect of media source bias and significance. We prove that news sources cite others despite different political views in accord with quality measures. However, in four English-speaking countries (US, UK, Canada, and Australia), the highest ranking sources all disproportionately favor left-wing parties, even when the majority of news sources exhibited conservative slants.
Cumulative Ionization in Optically Pumped Helium Discharges: A Source of Polarized Electrons (1972)

Polarization analysis of electrons extracted from a weak helium discharge in which the $2^{3}S_{1}$ metastable atoms are spin oriented by optical pumping indicates that the reaction $\mathrm{He}(2^{3}S_{1})+\mathrm{He}(2^{3}S_{1})\ensuremath{\rightarrow}\mathrm{He}(1^{1}S_{0})+{\mathrm{He}}^{+}+{e}^{\ensuremath{-}}$ is the predominant source of ionization in the discharge. The reaction conserves spin angular momentum and therefore produces polarized electrons. The process has been exploited to produce continuous beams of electrons with polarization as high as 10%. For a source-gas pressure of 0.035 torr, a continuous 4-\ensuremath{\mu}A beam with 8% spin polarization has been realized. Electrons extracted from the late afterglow of a pulsed discharge have 17% polarization at an optimum pressure of 0.1 torr.
335 GENETIC ENGINEERING OF GOATS FOR THE PRODUCTION OF A BIOSIMILAR ANTIBODY IN MILK (2012)

Dairy animals provide an attractive production platform for biosimilar antibodies due to the high protein production capacity of the mammary gland and easy access to milk. Goats are well suited for this approach as they offer a relatively short gestation time and good milk yield and are fully validated for the production of recombinant therapeutics. To generate transgenic goats capable of producing a biosimilar version of cetuximab, a monoclonal antibody for epidermal growth factor receptor and approved for the treatment of specific cancers, we co-transfected primary female fetal fibroblasts with expression constructs for cetuximab’s heavy (HC) and light (LC) chains under the control of the goat ß-casein regulatory sequences. Beta-globin insulators were added to both transgenes to minimize position effects, and an antibiotic selection marker was placed downstream of the HC transgene sequences to allow for the isolation of stable transgenic cell clones. Selected cell clones were screened by PCR for the presence of both transgenes. Positive cell clones were analysed by Southern blot with a ß-casein-specific probe. This allowed for the simultaneous detection of both transgenes, and the endogenous ß-casein gene served as a standard to determine transgene copy numbers. The cell clones showed a broad range of copy numbers, from single copy insertions to &gt;100 copies for the HC and LC transgenes. Interestingly, most of the cell clones had more LC than HC transgene copies. Ten cell clones were selected to generate transgenic founders using somatic cell nuclear transfer. We were able to produce 43 live kids from 9 cell lines following transfer of between 26 and 153 one- and two-cell embryos per line into recipients (range of 4 to 15 embryos per recipient). The one cell clone that we used unsuccessfully had the lowest number of transferred embryos (11). The efficiency for the production of live kids per transferred embryos was, on average, 5.1% (range of 1.0 to 9.7%). Kids from 5 lines were hormonally induced into lactation at the age of 10 weeks. Two lines with high copy numbers (=30) produced either no or only a few drops of milk, whereas the lines with =25 transgene copies gave up to several milliliters of milk per day. Western analyses confirmed cetuximab production levels of 15 g L–1 in 2 of the lines with =25 transgene copies and ~45 g L–1 in a high copy number line; one low copy number line showed good HC but very low LC expression. Our data demonstrate that cetuximab can be produced in significant quantities in transgenic goats. Future work is aimed at determining production levels under natural lactation conditions and characterising glycosylation patterns to fully understand the pharmacodynamic properties of the antibody.

<title>New optical ground station of the European Space Agency (ESA) at the Observatorio del Teide in Tenerife</title> (1997)

The Astronomical Instruments Group of Carl Zeiss Jena has supplied 13 RCC telescopes with 1 m aperture within the last 35 years. The last one of this series was procured by DARA together with a 12.5 m observatory dome from Zeiss to be used at the new optical ground station of ESA in Tenerife in 1991. The fully computer controlled astronomical telescope, however, will be utilized due to its versatile design for a rather diversified range of unique applications, such as optical communication via modulated laser beams to satellites and check-out of space debris. It has been equipped with a number of additional instrumentation, such as a 4 k by 4 k pixel CCD camera cooled with liquid nitrogen and a focal plane optical bench with highly sophisticated transmit and receive optics and high power lasers.
Development of a Vertical Stiffness Relationship for Belted Radial Tires (2005)

Abstract Vertical stiffness is a fundamentally important property of tires. This property is often expressed by some empirical formula not directly tied to the physics of the tire. It would be useful to have a physics‐based formula that could reliably predict vertical stiffness from a minimum set of pertinent, easily obtained parameters. This paper extends the ring model used by Koutny in his thermodynamic studies of tire stiffness and applies it directly to the question of vertical stiffness without regard to thermodynamics. A master curve of tire vertical stiffness is obtained that includes all tires that meet the assumptions of the model, regardless of size. A simple formula for tire vertical stiffness is developed from the master curve. The formula is correlated to a wide variety of tire stiffness measurements. One use of such a formula could be to develop more reliable tire load capacity standards. In the course of the analysis, it is found that the vertical stiffness depends significantly on the structural shear stiffness of the tire sidewalls.
Glyoxylic acid overcomes 1-MCP-induced blockage of fruit ripening in Pyrus communis L. var. ‘D’Anjou’ (2020)

1-methylcyclopropene (1-MCP) in an ethylene receptor antagonist that blocks ethylene perception and downstream ripening responses in climacteric fruit imparting a longer shelf life. However, in European pear, the application of 1-MCP irreversibly obstructs the onset of system 2 ethylene production resulting in perpetually unripe fruit with undesirable quality. Application of exogenous ethylene, carbon dioxide and treatment to high temperatures is not able to reverse the blockage in ripening. We recently reported that during cold conditioning, activation of alternative oxidase (AOX) occurs pre-climacterically. In this study, we report that activation of AOX via exposure of 1-MCP treated 'D'Anjou' pear fruit to glyoxylic acid triggers an accelerated ripening response. Time course physiological analysis revealed that ripening is evident from decreased fruit firmness and increased internal ethylene. Transcriptomic and functional enrichment analyses revealed genes and ontologies implicated in glyoxylic acid-mediated ripening, including AOX, TCA cycle, fatty acid metabolism, amino acid metabolism, organic acid metabolism, and ethylene-responsive pathways. These observations implicate the glyoxylate cycle as a biochemical hub linking multiple metabolic pathways to stimulate ripening through an alternate mechanism. The results provide information regarding how blockage caused by 1-MCP may be circumvented at the metabolic level, thus opening avenues for consistent ripening in pear and possibly other fruit.
Clustering With Multi-Layer Graphs: A Spectral Perspective (2012)

Observational data usually comes with a multimodal nature, which means that it can be naturally represented by a multi-layer graph whose layers share the same set of vertices (objects) with different edges (pairwise relationships). In this paper, we address the problem of combining different layers of the multi-layer graph for an improved clustering of the vertices compared to using layers independently. We propose two novel methods, which are based on a joint matrix factorization and a graph regularization framework respectively, to efficiently combine the spectrum of the multiple graph layers, namely the eigenvectors of the graph Laplacian matrices. In each case, the resulting combination, which we call a “joint spectrum” of multiple layers, is used for clustering the vertices. We evaluate our approaches by experiments with several real world social network datasets. Results demonstrate the superior or competitive performance of the proposed methods compared to state-of-the-art techniques and common baseline methods, such as co-regularization and summation of information from individual graphs.
Characterization of Palmprints by Wavelet Signatures via Directional Context Modeling (2004)

The palmprint is one of the most reliable physiological characteristics that can be used to distinguish between individuals. Current palmprint-based systems are more user friendly, more cost effective, and require fewer data signatures than traditional fingerprint-based identification systems. The principal lines and wrinkles captured in a low-resolution palmprint image provide more than enough information to uniquely identify an individual. This paper presents a palmprint identification scheme that characterizes a palmprint using a set of statistical signatures. The palmprint is first transformed into the wavelet domain, and the directional context of each wavelet subband is defined and computed in order to collect the predominant coefficients of its principal lines and wrinkles. A set of statistical signatures, which includes gravity center, density, spatial dispersivity and energy, is then defined to characterize the palmprint with the selected directional context values. A classification and identification scheme based on these signatures is subsequently developed. This scheme exploits the features of principal lines and prominent wrinkles sufficiently and achieves satisfactory results. Compared with the line-segments-matching or interesting-points-matching based palmprint verification schemes, the proposed scheme uses a much smaller amount of data signatures. It also provides a convenient classification strategy and more accurate identification.
Electrically Switchable Capillarity of Ionic Liquids (2012)

Abstract Electrocapillarity is the basis of modern electrowetting. And room temperature ionic liquids, an increasingly important set of electrolytes and organic salts that are liquid at room temperature, are considered a novel class of electrowetting agents, because of non-significant vapor pressure, nonflammability, good thermal stability, and a wide useable temperature range. In this paper, a simple device has been fabricated to investigate the electrocapillarity of ionic liquids. It shows attractive features involving wide operating temperature and in particular high stability, fast response and good reversibility at high temperatures. Besides, electrocapillarity of ionic liquids is strongly dependent on power supply frequency. In particular, high frequency, stable, reversible and wide height of rise modulations were obtained. The phenomenon of ionic liquids-based electrocapillarity was found to be affected by the structure and physicochemical properties of ionic liquids such as density, surface tension, alkyl carbon chain length of cation, type of the anion, etc., and the efficiency could be further improved through optimal choice of ambient phase or rational design and synthesis of ionic liquids.
Interferon Beta–Induced Restoration of Regulatory T-Cell Function in Multiple Sclerosis Is Prompted by an Increase in Newly Generated Naive Regulatory T Cells (2008)

The increase in T(reg)-cell inhibitory capacity mediated by interferon beta treatment can be explained by its effect on the homeostatic balance within the T(reg) cell compartment.
Structural Basis of Bcl‐x<sub>L</sub> Recognition by a BH3‐Mimetic α/β‐Peptide Generated by Sequence‐Based Design (2011)

The crystal structure of a complex between the prosurvival protein Bcl-x(L) and an α/β-peptide 21-mer is described. The α/β-peptide contains six β-amino acid residues distributed periodically throughout the sequence and adopts an α-helix-like conformation that mimics the bioactive shape of the Puma BH3 domain. The α/β-peptide forms all of the noncovalent contacts that have previously been identified as necessary for recognition of the prosurvival protein by an authentic BH3 domain. Comparison of our α/β-peptide:Bcl-x(L) structure with structures of complexes between native BH3 domains and Bcl-2 family proteins reveals how subtle adjustments, including variations in helix radius and helix bowing, allow the α/β-peptide to engage Bcl-x(L) with high affinity. Geometric comparisons of the BH3-mimetic α/β-peptide with α/β-peptides in helix-bundle assemblies provide insight on the conformational plasticity of backbones that contain combinations of α- and β-amino acid residues. The BH3-mimetic α/β-peptide displays prosurvival protein-binding preferences distinct from those of Puma BH3 itself, even though these two oligomers have identical side-chain sequences. Our results suggest origins for this backbone-dependent change in selectivity.

Male genitalia of these closely related species, all in the 'frithi' subgroup of the 'mylittalfrithi' group (a complex around 'A. platessa' Rothschild), are figured for comparision.
Isolation, characterization and phase transformation of new ginsenoside compound k hydrate and methanol solvates (2012)

Abstract Two new solvates of ginsenoside compound K (nonstoichiometric hydrate/CKH and methanol solvate/CKM) have been discovered and characterized in this paper. They were obtained through cooling crystallization in different solvents, and CKM could be prepared by transformation from CKH as well. The solvates were analysed by Power X‐ray diffraction (PXRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and fourier transform infrared (FTIR) spectroscopy. From the thermal studies, it is shown that the two new products are both solvates with different onset melting points. The PXRD and FTIR data support different crystal structures of them. It also describes the solution‐mediated phase transformation from CKH to CKM with a combination usage of process analytical technology tools. It is shown that the transformation process can be divided into three stages. The results reveal that seeding and low temperature help to accelerate the transformation, but initial solution concentration do little to the transformation kinetics. The kinetics and the rate‐controlling step for the transformation depend on the nucleation of the CKM. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Phytoconstituents and biological consequences of Aloe vera: A focused review (2018)

( Miller) is a perennial leaf succulent belonging to the Liliaceae family, and is called the silent healer. It is use as folk medicine, it is claimed that has wound and burn healing properties, and Aloe vera immunomodulatory effects. Also it is used in a commercial products because of these therapeutic attributes. It is being used as a whole extract, however, and the relationship between the components of the extract and its overall effect has not been elucidated. A precise understanding of the biologic activities of these is required to develop as a Aloe vera pharmaceutical source. Many attempts have been made to isolate single, biologically active components, to examine their effects, and clarify their functional mechanism. The present review focuses on the detailed composition of Aloe vera, its various phytocomponents having various biological properties that help to improve health and prevent disease conditions.
Correlational Neural Networks (2015)

Common representation learning (CRL), wherein different descriptions (or views) of the data are embedded in a common subspace, has been receiving a lot of attention recently. Two popular paradigms here are canonical correlation analysis (CCA)-based approaches and autoencoder (AE)-based approaches. CCA-based approaches learn a joint representation by maximizing correlation of the views when projected to the common subspace. AE-based methods learn a common representation by minimizing the error of reconstructing the two views. Each of these approaches has its own advantages and disadvantages. For example, while CCA-based approaches outperform AE-based approaches for the task of transfer learning, they are not as scalable as the latter. In this work, we propose an AE-based approach, correlational neural network (CorrNet), that explicitly maximizes correlation among the views when projected to the common subspace. Through a series of experiments, we demonstrate that the proposed CorrNet is better than AE and CCA with respect to its ability to learn correlated common representations. We employ CorrNet for several cross-language tasks and show that the representations learned using it perform better than the ones learned using other state-of-the-art approaches.
Differences in clinical and laboratory data of peritoneal dialysis patients selected according to body mass index. (2003)

The aim of the present study was to compare parameters of dietary intake, nutritional status, dialysis adequacy, and laboratory data between continuous ambulatory peritoneal dialysis (CAPD) patients having a normal body mass index (BMI) and those having an increased BMI. Two groups were selected: BMI = 20-25 (group I, n = 29) and BMI = 25-30 (group II, n = 19). No difference in age or peritoneal dialysis duration were observed between the study groups. Among parameters of dietary intake, only vitamin C ingestion was higher in group II than in group I. As compared with the patients in group I, the patients in group II showed significantly higher total body mass, lean body mass, fat body mass, and total body water. The Kt/V was lower in group II than in group I. In group II, values of serum iron concentration and transferrin saturation were both lower than those seen in group I. No differences were observed between the study groups for the other examined parameters. Those results show that overweight CAPD patients have higher anthropometric parameters and a lower Kt/V owing to a higher urea distribution volume. Disorders in iron parameters are more frequent in overweight patients. The observed differences do not influence duration of peritoneal dialysis treatment.
