description: Introduction: Expeditionary spaceflight is fraught with significant risks to human health, including trauma and other emergency medical events. To address several of the basic challenges of surgical care in reduced gravity, we are developing the Aqueous Immersion Surgical System (AISS), an optically clear enclosure pressurized by a fluid medium. The AISS is designed to prevent contamination of the spacecraft with blood and tissue debris, reduce intraoperative blood loss, and maintain visualization of the operative field. Methods: An early prototype of the AISS was tested in reduced gravity during parabolic flight. A clear, aqueous field was created in a watertight chamber containing a mock vascular network. Hemorrhage was simulated by severing several of the analogue vessels. Experiments were performed to evaluate the benefits of surrounding a surgical cavity with fluid medium, as compared to an air environment, with respect to maintaining a clear view and achieving hemostasis. Results: Qualitative evaluation of audio and video recorded during parabolic flight confirm AISS capacity to maintain visualization of the surgical field during a hemorrhage situation and staunch bleeding by raising interchamber pressure. Discussion: Evaluation of the AISS in reduced gravity corroborates observations in the literature regarding the difficulty in maintaining visualization of the surgical field when performing procedures in an air environment. By immersing the surgical field in fluid we were able to apply suction directly to the hemorrhage and also achieve hemostasis.

description: We extend the simple scenario for $Ψ'$ decays suggested a few years ago. The $c\bar c$ pair in the $Ψ'$ does not annihilate directly into three gluons but rather survives before annihilating. An interesting prediction is that a large fraction of all $Ψ'$ decays could originate from the $Ψ' \to η_{c} (3π)$ channel which we urge experimentalists to identify. Our model solves the problem of the apparent hadronic excess in $Ψ'$ decays as well as the $ρπ$ puzzle since, in our view, the two-body decays of the $Ψ'$ are naturally of electromagnetic origin. Further tests of this picture are proposed, e.g. $J/Ψ\to b_{1}η$.

description: We study the influence of a periodic perturbation of the effective masses of the nucleons, due to the assumed semi-classical ultra-light dark matter background, on the motion of neutrons in a gravitational quantum well. Our focus is on the transition probability between the lowest two energy states, with the Rabi frequency in the kHz region corresponding to the series of "sweet spot" dark matter masses in the $10^{-11}$eV ballpark. The relevant probability is written in terms of the specific mass and of the effective coupling to the ordinary matter. These parameters can be constrained by the non-observation of any significant deviations of the measured transition probabilities from the dark-matter-free picture.

description: Silicon carbide dust is ubiquitous in circumstellar envelopes around C-rich AGB stars. However, the main gas-phase precursors leading to the formation of SiC dust have not yet been identified. The most obvious candidates among the molecules containing an Si--C bond detected in C-rich AGB stars are SiC2, SiC, and Si2C. We aim to study how widespread and abundant SiC2, SiC, and Si2C are in envelopes around C-rich AGB stars and whether or not these species play an active role as gas-phase precursors of silicon carbide dust in the ejecta of carbon stars. We carried out sensitive observations with the IRAM 30m telescope of a sample of 25 C-rich AGB stars to search for emission lines of SiC2, SiC, and Si2C in the 2 mm band. We performed non-LTE excitation and radiative transfer calculations based on the LVG method to model the observed lines of SiC2 and to derive SiC2 fractional abundances in the observed envelopes. We detect SiC2 in most of the sources, SiC in about half of them, and do not detect Si2C in any source, at the exception of IRC +10216. Most of these detections are reported for the first time in this work. We find a positive correlation between the SiC and SiC2 line emission, which suggests that both species are chemically linked, the SiC radical probably being the photodissociation product of SiC2 in the external layer of the envelope. We find a clear trend in which the denser the envelope, the less abundant SiC2 is. The observed trend is interpreted as an evidence of efficient incorporation of SiC2 onto dust grains, a process which is favored at high densities owing to the higher rate at which collisions between particles take place. The observed behavior of a decline in the SiC2 abundance with increasing density strongly suggests that SiC2 is an important gas-phase precursor of SiC dust in envelopes around carbon stars.

description: The microtubule network plays critical roles in many cellular processes, and quantitative models of how its organization varies across cell types and conditions are required for understanding those roles and as input to cell simulations. High-throughput image acquisition technologies are potentially valuable for this purpose, but do not provide sufficient resolution for current analysis methods that rely on tracing of individual microtubules. We describe a parametric conditional model of microtubule distribution that can generate a microtubule network in intact cells using a persistent random walk approach. The model parameters are physically meaningful as they directly describe the spatial distribution of microtubules and include the number of microtubules as well as the mean of the length distribution. We also present an indirect method for estimating the parameters of the model from three-dimensional fluorescence microscope images of cells that relies on comparing acquired images with simulated images generated from the model. Our results show that our method can reasonably recover parameters for a given query image, and we present the distributions of parameters estimated by our method for a collection of HeLa cell images.

description: The estimation of potential fields such as the gravitational or magnetic potential at the surface of a spherical planet from noisy observations taken at an altitude over an incomplete portion of the globe is a classic example of an ill-posed inverse problem. Here we show that the geodetic estimation problem has deep-seated connections to Slepian's spatiospectral localization problem on the sphere, which amounts to finding bandlimited spherical functions whose energy is optimally concentrated in some closed portion of the unit sphere. This allows us to formulate an alternative solution to the traditional damped least-squares spherical harmonic approach in geodesy, whereby the source field is now expanded in a truncated Slepian function basis set. We discuss the relative performance of both methods with regard to standard statistical measures as bias, variance and mean-square error, and pay special attention to the algorithmic efficiency of computing the Slepian functions on the region complementary to the axisymmetric polar gap characteristic of satellite surveys. The ease, speed, and accuracy of this new method makes the use of spherical Slepian functions in earth and planetary geodesy practical.

description: It is now a common practice to use local magnetic parameters such as magnetic decay index for explaining solar eruptions from active regions, but there can be an alternative view that the global properties of the source region should be counted as a more important factor. We discuss this issue based on {\it Solar Dynamics Observatory} (SDO) observations of the three successive eruptions within 1.5 hours from the NOAA active region 11444 and the magnetic parameters calculated using the nonlinear force-free field (NLFFF) model. Two violent eruptions occurred in the regions with relatively high magnetic twist number (0.5--1.5) and high decay index (0.9--1.1) at the nominal height of the filament (12$''$) and otherwise a mild eruption occurred, which supports the local parameter paradigm. Our main point is that the time sequence of the eruptions did not go with these parameters. It is argued that an additional factor, in the form of stabilizing force, should operate to determine the onset of the first eruption and temporal behaviors of subsequent eruptions. As supporting evidence, we report that the heating and fast plasma flow continuing for a timescale of an hour was the direct cause for the first eruption, and that the unidirectional propagation of the disturbance determined the timing of subsequent eruptions. Both of these factors are associated with the overall magnetic structure rather than local magnetic properties of the active region.

description: Image segmentation is important with applications to several problems in biology and medicine. While extensively researched, generally, current segmentation methods perform adequately in the applications for which they were designed, but often require extensive modifications or calibrations before being used in a different application. We describe an approach that, with few modifications, can be used in a variety of image segmentation problems. The approach is based on a supervised learning strategy that utilizes intensity neighborhoods to assign each pixel in a test image its correct class based on training data. We describe methods for modeling rotations and variations in scales as well as a subset selection for training the classifiers. We show that the performance of our approach in tissue segmentation tasks in magnetic resonance and histopathology microscopy images, as well as nuclei segmentation from fluorescence microscopy images, is similar to or better than several algorithms specifically designed for each of these applications.

description: Rieger-type periodicity has been detected in different activity indices over many solar cycles. It was recently shown that the periodicity correlates with solar activity having a shorter period during stronger cycles. Solar activity level is generally asymmetric between northern and southern hemispheres, which could suggest the presence of a similar behavior in the Rieger-type periodicity. We analyse the sunspot area/number and the total magnetic flux data for northern and southern hemispheres during solar cycles 19-23 which had remarkable north-south asymmetry. Using wavelet analysis of sunspot area and number during the north-dominated cycles (19-20) we obtained the periodicity of 160-165 days in the stronger northern hemisphere and 180-190 days in the weaker southern hemisphere. On the other hand, south-dominated cycles (21-23) display the periodicity of 155-160 days in the stronger southern hemisphere and 175-188 days in the weaker northern hemisphere. Therefore, the Rieger-type periodicity has the north-south asymmetry in sunspot area/number data during solar cycles with strong hemispheric asymmetry. We suggest that the periodicity is caused by magnetic Rossby waves in the internal dynamo layer. Using the dispersion relation of magnetic Rossby waves and observed Rieger periodicity we estimated the magnetic field strength in the layer as 45-49 kG in more active hemispheres (north during the cycles 19-20 and south during the cycles 21-23) and 33-40 kG in weaker hemispheres. The estimated difference in the hemispheric field strength is around 10 kG, which provides a challenge for dynamo models. Total magnetic flux data during the cycle 20-23 reveals no clear north-south asymmetry which needs to be explained in the future.

description: We report on evolutionary calculations of the onset of mass transfer in AM CVn binaries, treating the donor's evolution in detail. We show that during the early contact phase, while the mass transfer rate, $\Mdot$, is increasing, gravity wave (GW) emission continues to drive the binary to shorter orbital period, $\Porb$. We argue that the phase where $\Mdot > 0$ and $\nudot > 0$ ($ν= 1/\Porb$) can last between $10^3$ and $10^6$ yrs, significantly longer than previously estimated. These results are applied to RX J0806+1527 ($\Porb = 321$ s) and RX J914+2456 ($\Porb=569$ s), both of which have measured $\nudot > 0$. \emph{Thus, a $\nudot > 0$ does not select between the unipolar inductor and accretion driven models proposed as the source of X-rays in these systems}. For the accretion model, we predict for RX J0806 that $\ddotν \approx \ee{1.0-1.5}{-28}$ Hz s$^{-2}$ and argue that timing observations can probe $\ddotν$ at this level with a total $\approx 20$ yr baseline. We also place constraints on each system's initial parameters given current observational data.

5.2 A Library Infrastructure for the Practices of Scholarly Communication

Subjects: Open Access books, innovation, wider audience, quality control

description: Stockholm University Press, founded in 2014, will publish its first Open Access books in early 2015, and one academic journal is already up and running. This presentation will cover the current challenges for Stockholm University Press, how we plan to move forward in the immediate future, and last but not least outline plans for further developments. As a new player in the arena of scholarly communication, with ambitions to reach the highest international level, the competition is stiff. The innovative working model with exchange of ideas and best practices through strategic international partnerships with other university presses will build a sustainable model for publication of peer-reviewed books and journals. The aim is to create more options for researchers at the university to communicate their results to a wider audience. The practice of running the press raises a number of questions: how does the library provide a reliable infrastructure worthy of academic exchange of ideas on an international level; how do we make the review process count in relation to evaluation methods of scholarly work; how do we provide a publishing service that benefits the researchers to a greater extent in comparison with traditional models; and how can the library act as a centre of excellence collecting knowledge about scholarly communication in relation to the publishing entity? Stockholm University Press is now implementing an online infrastructure for a peer-review process for quality control for Open Access monographs and book chapters. The quality control workflow has been developed in close collaboration with active scholars as well as a strategic partner, a company called Ubiquity Press. The evaluation process managed by the editorial teams of researchers should be rigorous, transparent, efficient, and follow international guidelines on publication ethics. We believe that the researcher-led publishing approach will lead to more usage, more citations and more recognition for the work done by scholars. not only in the number of papers published but also through recognition of the peer-review process by using the bibliometrics created. Sofie Wennström has a Bachelor’s Degree in Education from Stockholm University, and is working as a Researcher in the Department of Quality in Stockholm University Library. She has over 10 years’ experience of working at one of the largest academic publishers in the world, and brings that know-how to the Library to develop Stockholm University Press and the ibrary services further as a centre of excellence for scholarly communication.

description: How eruption can recur from a confined magnetic structure is discussed based on the {\it Solar Dynamics Observatory} (SDO) observations of the NOAA active region 11444, which produced three eruptions within 1.5 hours on March 27, 2012. The active region had the positive polarity magnetic fields in the center surrounded by the negative polarity fields around. Since such a distribution of magnetic polarity tends to form a dome-like magnetic fan structure confined over the active region, the multiple eruptions was puzzling. Our investigation reveals that this event exhibits several properties distinct from other eruptions associated with magnetic fan structures: (i) a long filament encircling the active region was present before the eruptions; (ii) expansion of the open-closed boundary of the field lines after each eruption suggestive of the growing fan-dome structure, and (iii) the ribbons inside the closed magnetic polarity inversion line evolving in response to the expanding open-closed boundary. It thus appears that in spite of multiple eruptions the fan-dome structure remained undamaged, and the closing back field lines after each eruption rather reinforced the fan-dome structure. We argue that the multiple eruptions could occur in this active region in spite of its confined magnetic structure because the filament encircling the active region was adequate for slipping through the magnetic separatrix to minimize the damage to its overlying fan-dome structure. The result of this study provides a new insight into the productivity of eruptions from a confined magnetic structure.

description: We describe a new supervised learning-based template matching approach for segmenting cell nuclei from microscopy images. The method uses examples selected by a user for building a statistical model that captures the texture and shape variations of the nuclear structures from a given dataset to be segmented. Segmentation of subsequent, unlabeled, images is then performed by finding the model instance that best matches (in the normalized cross correlation sense) local neighborhood in the input image. We demonstrate the application of our method to segmenting nuclei from a variety of imaging modalities, and quantitatively compare our results to several other methods. Quantitative results using both simulated and real image data show that, while certain methods may work well for certain imaging modalities, our software is able to obtain high accuracy across several imaging modalities studied. Results also demonstrate that, relative to several existing methods, the template-based method we propose presents increased robustness in the sense of better handling variations in illumination, variations in texture from different imaging modalities, providing more smooth and accurate segmentation borders, as well as handling better cluttered nuclei.

description: Node-perturbation learning is a type of statistical gradient descent algorithm that can be applied to problems where the objective function is not explicitly formulated, including reinforcement learning. It estimates the gradient of an objective function by using the change in the object function in response to the perturbation. The value of the objective function for an unperturbed output is called a baseline. Cho et al. proposed node-perturbation learning with a noisy baseline. In this paper, we report on building the statistical mechanics of Cho's model and on deriving coupled differential equations of order parameters that depict learning dynamics. We also show how to derive the generalization error by solving the differential equations of order parameters. On the basis of the results, we show that Cho's results are also apply in general cases and show some general performances of Cho's model.

The data processing the data are transformed during the data processing into a suitable coordinate system, the noise is removed, and finally the velocity field is calculated. Resulting velocities are compared with the model velocities and the calibration is done. From our results it becomes clear that this method could be applied to full-disc dopplergrams acquired by the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SoHO).

We propose to use this interferometer as a readout mechanism for future inertial sensors, removing a major limiting noise source, and in precision positioning systems. The interferometers peak sensitivity is $2 \times 10^{-{14}}$ m/${\sqrt{\rm{Hz}}}$ at 70 Hz and $8 \times 10^{-{11}}$ m/$\sqrt{\rm{Hz}}$ at 10 mHz. If deployed on a GS-13 geophone, the resulting inertial sensing output will be dominated by suspension thermal noise from 50 mHz to 2 Hz.

description: The wake induced in a hot QCD medium by a high momentum parton (jet precursor) is calculated in the framework of linear response theory. Two different scenarios are discussed: a weakly coupled quark gluon plasma (pQGP) as described by hard-thermal loop (HTL) perturbation theory and a strongly cupled QGP (sQGP) with the properties of a quantum liquid. In the latter case the wake could exhibit a pronounced Mach cone structure. This physical mechanism could be important for the understanding of preliminary data from the PHENIX and STAR experiments at RHIC on the angular distribution of low-pt secondaries stemming from the away-side jet which indicate maxima at $Δϕ=π\pm 1.1$.

description: An unusual set of circumstances led to three siblings from Greenock, Scotland, meeting in Cairo during WW2.Oldest sibling, Lt. Alastair McKillop, arrived in Iraq in December 1942 aged 29, and joined his unit, the 6th Seaforth Highlanders in February 1943.Meanwhile, youngest sibling, RAF pilot Ronnie McKillop, arrived in North Africa in January 1943, aged 22 and was stationed in Benin, Libya, flying mostly Hurricanes and later Spitfires, with 243 Wing 33 Squadron.Both brothers were wounded the same year, Alastair during the invasion of Sicily which he writes about in the two letters to his father that accompany this story. Ronnie was shot down twice, once over the Med and once over land, the second of which accounts for his visiting the No 5 RAF General Hospital in Cairo in September 1943.Meanwhile Alastair had led Seaforth troops ashore in the July invasion of Sicily and had been wounded in the advance between Priolo and Augusta on the south-eastern coast on the 12th July. The letters he wrote to his father back in Greenock give a detailed account of the invasion from his point of view and detail other men wounded or killed, as well as an account of his own wounding and his perilous journey back for medical attention. He too, ended up in hospital in Cairo and the letters, written in December that year, by which time he had been made Camp Commandant at a camp in 87 Sub Area Aleppo, indicate that he is still not fit for duty. How amazing that the two serving brothers, one RAF, one Army, should meet in Cairo in the middle of war. Even more amazing is the fact that their sister, Isabel, about 27 at the time, had joined the Queen Alexandra Nursing Corps and was reunited with them both in Cairo that same September. We do not know how long she was there, but Alastair’s December 1943 letter indicates that he thinks she had already left for Britain. One of Isabel’s daughters recounts that she used to tell a story of Alastair emerging out of the desert with a bedraggled group of men, eating a hearty meal and then disappearing once more into the sand dunes. There is certainly a photo of Alastair and Ronnie at the Cairo YMCA tucking into what looks like a hearty meal. Presumably it was taken by Isabel.All three siblings survived the war. Ronnie returned to Britain and provided aerial cover for the D-Day landings.Alastair returned to the 6th Seaforths on the Italian mainland just north of Anzio in May 1944 and was wounded again and this time captured. He spent the rest of the war in a POW camp in Germany but returned home safely at the end of the war.Submitted by Alastair’s daughters Anne and Christine.

description: We present a combinatorial and computational commutative algebra methodology for studying singularities of Schubert varieties of flag manifolds. We define the combinatorial notion of *interval pattern avoidance*. For "reasonable" invariants P of singularities, we geometrically prove that this governs (1) the P-locus of a Schubert variety, and (2) which Schubert varieties are globally not P. The prototypical case is P="singular"; classical pattern avoidance applies admirably for this choice [Lakshmibai-Sandhya'90], but is insufficient in general. Our approach is analyzed for some common invariants, including Kazhdan-Lusztig polynomials, multiplicity, factoriality, and Gorensteinness, extending [Woo-Yong'05]; the description of the singular locus (which was independently proved by [Billey-Warrington '03], [Cortez '03], [Kassel-Lascoux-Reutenauer'03], [Manivel'01]) is also thus reinterpreted. Our methods are amenable to computer experimentation, based on computing with *Kazhdan-Lusztig ideals* (a class of generalized determinantal ideals) using Macaulay 2. This feature is supplemented by a collection of open problems and conjectures.

description: Using Spitzer IRAC mid-infrared imaging from the Great Observatories Origins Deep Survey, we study z_850-dropout sources in the Hubble Ultra Deep Field. After carefully removing contaminating flux from foreground sources, we clearly detect two z_850-dropouts at 3.6 micron and 4.5 micron, while two others are marginally detected. The mid-infrared fluxes strongly support their interpretation as galaxies at z~7, seen when the Universe was only 750 Myr old. The IRAC observations allow us for the first time to constrain the rest-frame optical colors, stellar masses, and ages of the highest redshift galaxies. Fitting stellar population models to the spectral energy distributions, we find photometric redshifts in the range 6.7-7.4, rest-frame colors U-V=0.2-0.4, V-band luminosities L_V=0.6-3 x 10^10 L_sun, stellar masses 1-10 x 10^9 M_sun, stellar ages 50-200 Myr, star formation rates up to ~25 M_sun/yr, and low reddening A_V<0.4. Overall, the z=7 galaxies appear substantially less massive and evolved than Lyman break galaxies or Distant Red Galaxies at z=2-3, but fairly similar to recently identified systems at z=5-6. The stellar mass density inferred from our z=7 sample is rho* = 1.6^{+1.6}_{-0.8} x 10^6 M_sun Mpc^-3 (to 0.3 L*(z=3)), in apparent agreement with recent cosmological hydrodynamic simulations, but we note that incompleteness and sample variance may introduce larger uncertainties. The ages of the two most massive galaxies suggest they formed at z>8, during the era of cosmic reionization, but the star formation rate density derived from their stellar masses and ages is not nearly sufficient to reionize the universe. The simplest explanation for this deficiency is that lower-mass galaxies beyond our detection limit reionized the universe.

description: The change in exocrine mass is an important parameter to follow in experimental models of pancreatic injury and regeneration. However, at present, the quantitative assessment of exocrine content by histology is tedious and operator-dependent, requiring manual assessment of acinar area on serial pancreatic sections. In this study, we utilized a novel computer-generated learning algorithm to construct an accurate and rapid method of quantifying acinar content. The algorithm works by learning differences in pixel characteristics from input examples provided by human experts. HE-stained pancreatic sections were obtained in mice recovering from a 2-day, hourly caerulein hyperstimulation model of experimental pancreatitis. For training data, a pathologist carefully outlined discrete regions of acinar and non-acinar tissue in 21 sections at various stages of pancreatic injury and recovery (termed the "ground truth"). After the expert defined the ground truth, the computer was able to develop a prediction rule that was then applied to a unique set of high-resolution images in order to validate the process. For baseline, non-injured pancreatic sections, the software demonstrated close agreement with the ground truth in identifying baseline acinar tissue area with only a difference of 1% ± 0.05% (p = 0.21). Within regions of injured tissue, the software reported a difference of 2.5% ± 0.04% in acinar area compared with the pathologist (p = 0.47). Surprisingly, on detailed morphological examination, the discrepancy was primarily because the software outlined acini and excluded inter-acinar and luminal white space with greater precision. The findings suggest that the software will be of great potential benefit to both clinicians and researchers in quantifying pancreatic acinar cell flux in the injured and recovering pancreas.

description: We investigate the inclusive Higgs boson production in proton-proton collisions at the CERN LHC conditions using the $k_T$-factorization approach. Our analysis is based on the dominant off-shell gluon-gluon fusion subprocess (where the transverse momenta of initial gluons are taken into account) and covers $H \to γγ$, $H \to ZZ^* \to 4l$ (where $l = e,μ$) and $H \to W^+ W^- \to e^\pm μ^\mp ν\bar ν$ decay channels. The transverse momentum dependent (or unintegrated) gluon densities in a proton were derived from Ciafaloni-Catani-Fiorani-Marchesini equation or, alternatively, were chosen in accordance with Kimber-Martin-Ryskin prescription. We estimate the theoretical uncertainties of our calculations and compare our results with next-to-next-to-leading-order plus next-to-next-to-leading-logarithmic ones obtained using collinear QCD factorization. Our predictions agree well with the latest experimental data taken by the CMS and ATLAS Collaborations at $\sqrt s = 8$ and $13$~TeV.

description: Medien haben einen entscheidenden Einfluss auf die öffentliche Meinung, da sie eine primäre Kommunikationsquelle der modernen Gesellschaftsind. Allerdings hat Media Bias, welcher Auftritt, wenn Medien einseitig bzw. voreingenommen berichten oder diskriminieren, das Potenzial, Menschen mit Fehlinformationen oder polarisierenden Ansichten in nicht wünschenswerten Hinsichten zu beeinflussen.Unter Berücksichtigung aktuellerFortschritte im Bereich des maschinellen Lernens ist die natürliche Sprachverarbeitung (NLP) zu einem starken Werkzeug für die Erkennung undÄnderung von Media Bias geworden. Die vorliegende Dissertation stellt diesbzüglich eine umfassende Untersuchung von Media Bias dar, welchedie Erstellung von Datensätzen, die Entwicklung von computergestützten Modellen und sowohl quantitative, als auch qualitative Analysen umfasst.Insbesondere untersuchen wir drei unterschiedliche Arten von Media Bias: Gatekeeping Bias (die Auswahl des zu Berichtenden), Coverage Bias (dieSichtbarkeit verschiedener Standpunkte), und Statement Bias (die Meinungen von politischen Lagern).
description: Media plays a vital role in shaping public opinion, as it serves as a primary source of communication in modern society. However, media bias, occurring when media exhibit favoritism or discrimination in their reporting, may potentially influence people in undesirable directions by presenting misinformed or polarized views. In light of the recent advancements in machine learning, natural language processing (NLP) has become a powerful instrument for tackling media bias in terms of detecting or changing the bias in texts. With this in mind, this dissertation delves into the comprehensive examination of media bias, including corpora creation, computational model development, and both quantitative and qualitative analyses. In particular, we study three different kinds of media biases, namely gatekeeping bias (selection of what to report), coverage bias (visibility of each side), and statement bias (opinions of political sides).
