Machine Learning for Understanding Focal Epilepsy
Creators: name: D'AMARIO, VANESSA
Publisher: name: Universit� degli studi di Genova
Year: 2020

description: The study of neural dysfunctions requires strong prior knowledge on brain physiology combined with expertise on data analysis, signal processing, and machine learning. One of the unsolved issues regarding epilepsy consists in the localization of pathological brain areas causing seizures. Nowadays the analysis of neural activity conducted with this goal still relies on visual inspection by clinicians and is therefore subjected to human error, possibly leading to negative surgical outcome. In absence of any evidence from standard clinical tests, medical experts resort to invasive electrophysiological recordings, such as stereoelectroencephalography to assess the pathological areas. This data is high dimensional, it could suffer from spatial and temporal correlation, as well as be affected by high variability across the population. These aspects make the automatization attempt extremely challenging. In this context, this thesis tackles the problem of characterizing drug resistant focal epilepsy. This work proposes methods to analyze the intracranial electrophysiological recordings during the interictal state, leveraging on the presurgical assessment of the pathological areas. The first contribution of the thesis consists in the design of a support tool for the identification of epileptic zones. This method relies on the multi-decomposition of the signal and similarity metrics. We built personalized models which share common usage of features across patients. The second main contribution aims at understanding if there are particular frequency bands related to the epileptic areas and if it is worthy to focus on shorter periods of time. Here we leverage on the post-surgical outcome deriving from the Engel classification. The last contribution focuses on the characterization of short patterns of activity at specific frequencies. We argue that this effort could be helpful in the clinical routine and at the same time provides useful insight for the understanding of focal epilepsy.

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present a photometric study of the globular clusters (GCs) in the Virgo giant elliptical galaxy M86 based on Washington CT1 images. The colors of the GCs in M86 show a bimodal distribution with a blue peak at (C -T1) = 1.30 and a red peak at (C -T1) = 1.72. The spatial distribution of the red GCs is elongated similarly to that of the stellar halo, while that of the blue GCs is roughly circular. The radial number density profile of the blue GCs is more extended than that of the red GCs. The radial number density profile of the red GCs is consistent with the surface brightness profile of the M86 stellar halo. The GC system has a negative radial color gradient, which is mainly due to the number ratio of the blue GCs to the red GCs increasing as galactocentric radius increase. The bright blue GCs in the outer region of M86 show a blue tilt: the brighter they are, the redder their mean colors get. These results are discussed in comparison with other Virgo giant elliptical galaxies.

Gravitational Emergence from Dimensional Curl:  Twist Geometry as the Source of Gravitation in  the Sixta Framework
Creators: name: Sixta, David
Publisher: name: Zenodo
Year: 2025
Subjects: subject: quantum gravity
subject: Gravity

description:  This paper proposes that gravity is not a fundamental force but an emergent phenomenon arising from dimensional curl in the recursive twist phase manifold. In Sixta Theory, mass is defined as a topological knot  in harmonic space, and gravity results from the curvature of phase space  surrounding such knots. We introduce the concept of gravitational field  strength as second-order phase curvature and demonstrate that spacetime curvature is a projected illusion of twist gradient dynamics.

description: We present a modern ephemeris and modern light curve of the first-discovered Cepheid variable in M31, Edwin Hubble's M31-V1. Observers of the American Association of Variable Star Observers undertook these observations during the latter half of 2010. The observations were in support of an outreach program by the Space Telescope Science Institute's Hubble Heritage project, but the resulting data are the first concentrated observations of M31-V1 made in modern times. AAVSO observers obtained 214 V-band, Rc-band, and unfiltered observations from which a current ephemeris was derived. The ephemeris derived from these observations is JD(Max) = 2455430.5(+/-0.5) + 31.4 (+/-0.1) E. The period derived from the 2010 data are in agreement with the historic values of the period, but the single season of data precludes a more precise determination of the period or measurement of the period change using these data alone. However, using an ephemeris based upon the period derived by Baade and Swope we are able to fit all of the observed data acceptably well. Continued observations in the modern era will be very valuable in linking these modern data with data from the 1920s-30s and 1950s, and will enable us to measure period change in this historic Cepheid. In particular, we strongly encourage intensive observations of this star around predicted times of maximum to constrain the date of maximum to better than 0.5 days.

description: The Atacama Large Millimeter Array (ALMA) gives us access to the densest molecular gas on sub-kiloparsec scales, providing valuable insight into the physical and chemical processes that regulate star formation. We will present recent work on the CN (1-0)/CO (1-0) intensity ratio for a large sample of nearby Ultra-Luminous and Luminous Infrared Galaxies (U/LIRGs) utilizing the power of the ALMA archive. We identify 16 U/LIRGs which have been previously observed and detected in both the CN (1-0) and CO (1-0) lines at ∼500 parsec resolution based on 16 different ALMA projects. We will discuss how the CN/CO line ratio varies both within individual U/LIRGs and between ULIRGs and LIRGs as independent samples. The CN/CO line ratio is higher in ULIRGs than LIRGs, with a larger spread in the ratio measured for LIRGs due to the variety of galaxy environments included in our sample; e.g., starburst nuclei and quiescent disks, nearby galaxy mergers, and active galactic nuclei (AGN) in Seyfert galaxies. Additionally, we will present new results correlating the global CN/CO ratio in these extreme systems with global galaxy properties of total infrared luminosity, merger stage, AGN contribution, [CII] and [OI] luminosities, and star formation rate measured from both infrared luminosity and radio continuum.

description: Die Analyse großer Datensätze aus Online-Plattformen („Big Data“) wirft eine Reihe von methodologischen Fragen auf, die insbesondere das Verhältnis von Theorie und Empirie betreffen. Während an vielen Stellen Begeisterung für neue, datenorientierte Forschungsmöglichkeiten zu hören ist, befürchten andere ein „Ende der Theorie“. Der Beitrag zeigt verschiedene Aspekte dieses Problembereichs auf und macht Vorschläge, wie Big-Data-Studien theoretisch gehaltvoll gestaltet werden können. Beispiele aus der Agenda-Setting­, Sozialkapital- und Diffusionsforschung werden diskutiert. Interdisziplinäre Zusammenarbeit und systematische Validierung von Big-Data-Verfahren erscheinen dabei als zentrale Desiderate. Welchen Stellenwert Big-Data-Ansätze in der kommunikationswissenschaftlichen Forschung und Lehre in Zukunft haben werden, hängt mutmaßlich auch von ihrer Fähigkeit zu theoretischer Innovation ab.
description: With the arrival of "big data" analysis, the traditional relationship between theoretical and empirical work in social science research has been put into question. While some are enthusiastic about new data-oriented research opportunities, others fear that the "end of theory" is near. The paper focuses on different aspects of this concern and proposes ways that theory can be used to enrich big data studies. Central to this are examples from agenda setting, social capital, and diffusion research. Interdisciplinary collaboration and systematic validation of big data methods seem to be key in advancing data-driven research, and their future role in communication’s research and teaching will likely depend on the potential for theoretical innovation within big data approaches.

description: We derive interatomic potentials for zinc blende InAs, InP, GaAs and GaP semiconductors with possible applications in the realm of nanostructures. The potentials include bond stretching interaction between the nearest and next-nearest neighbors, a three body term and a long-range Coulomb interaction. The optimized potential parameters are obtained by (i) fitting to bulk phonon dispersions and elastic properties and (ii) constraining the parameter space to deliver well behaved potentials for the structural relaxation and vibrational properties of nanostructure clusters. The targets are thereby calculated by density functional theory for clusters of up to 633 atoms. We illustrate the new capability by the calculation Kleinman and Grüneisen parameters and of the vibrational properties of nanostructures with 3 to 5.5 nm diameter.

description: In recent years, Big Data – or the automated processing of huge amounts of data for social science purposes – has stirred much debate and controversy within academia. Not only does Big Data raise new methodological and theoretical questions, but its ethical implications also increasingly come into focus. The paper examines some particularities of big data analysis (especially within the context of social media), and highlights the ways they challenge research ethics standards. Central to this issue is the status of users – the people behind the data – in this type of research. In addition, some general implications of Big Data methods for social science research will be examined. Overall, the aim is to sensitize researchers to the ethical issues implict to Big Data research and to encourage a broader disucssion of these issues within the scientific community.
Nanoscale investigation of chromatin organization by structured illumination microscopy
Creators: name: CAINERO, ISOTTA
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: This thesis work aims to present a novel approach to reconstruct Structured Illumination Microscopy, SIM, raw data and to analyze SIM reconstructed images. These new approaches will be demonstrated in the study of chromatin organization.
The dissertation will be articulated as follows:
Chapter 1 provides an introduction to chromatin nanoscale organization and optical fluorescence microscopy, which is one of the main tools involved in life sciences studies. Indeed, optical microscopy allowed investigating, with high specificity and sensitivity, living samples such as cells, and even tissues. The reader will be presented with a summary on the fluorescence optical microscopy and on the super-resolution, SR, techniques available today including SIM, which is the microscope used in this thesis work.
In Chapter 2 the focus is on the introduction of a new reconstruction tool for specific SR-SIM microscopy powered by the Separation of Photons by Lifetime Tuning, SPLIT, method. The introduction of the concept, applied in other works to different SR techniques, will be followed by the practical implementation of the method on the SIM microscope. Then, the applicability of the technique, which we called SPLIT-SIM, will be demonstrated on several different samples. Indeed, it will be used on Simulated data, on test experimental beads, on biological samples both in one and two-color staining.
In Chapter 3 the focus will move on the coupling of SIM reconstructed data to colocalization analysis. In particular, for the first time, SIM was coupled to Image Cross-Correlation Spectroscopy, ICCS, in the study of two-color images of a model sample. DNA origami-based structures were chosen as a model sample with precise distances allowing for evaluation of the analysis results. Moreover, all the images analyzed by the pixel-based technique, SIM-ICCS, were analyzed also with an object-based technique as a comparison to evaluate which could be the best choice in SIM acquisitions.
Finally, Chapter 4 will be focused on the application of the analysis, performed in chapter 3, to two-color SIM images of nuclear structure. The analysis will be performed on ?positive control? in which the target structures will be colocalized and on a negative control in which the structured are spatially segregated within the nucleus. Both object-based and pixel-based analysis will be able to extract coherent results thus showing how SIM-ICCS can become an interesting and useful tool to analyze SIM multicolor acquisitions.

description: Three dimensional Gödel black hole is a solution to Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant. We have studied the hidden conformal symmetry for massive scalar field without any additional condition in the background of three dimensional non-extremal and extremal Gödel black holes. This conformal symmetry is uncovered by the observation that the radial wave equations in both cases can all be rewritten in the form of $SL(2, R)$ Casimir operators through introducing two sets of conformal coordinates to write the $SL(2, R)$ generators. At last, we give the holographic dual descriptions of Bekenstein-Hawking entropies of non-extremal and extremal black holes from Cardy formula of conformal field theory.

Quantum critical point for stripe order: An organizing principle of cuprate superconductivity

description: A spin density-wave quantum critical point (QCP) is the central organizing principle of organic, iron-pnictide, heavy-fermion and electron-doped cuprate superconductors. It accounts for the superconducting Tc dome, the non-Fermi-liquid resistivity, and the Fermi-surface reconstruction. Outside the magnetically ordered phase above the QCP, scattering and pairing decrease in parallel as the system moves away from the QCP. Here we argue that a similar scenario, based on a stripe-order QCP, is a central organizing principle of hole-doped cuprate superconductors. Key properties of Eu-LSCO, Nd-LSCO and YBCO are naturally unified, including stripe order itself, its QCP, Fermi-surface reconstruction, the linear-T resistivity, and the nematic character of the pseudogap phase.

Size- and shape-controlled platinum and palladium nanoparticles for catalytic and biomedical applications
Creators: name: MASTRONARDI, VALENTINA
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: The aim of this doctoral project has been centered on the development of innovative green synthetic methods able to govern the key physico-chemical properties of noble metal nanoparticles (NPs). To fully uncover the potential of metallic NPs, it is necessary to finely control the shape of nanomaterials while keeping the ultra-small characteristics, in order to achieve superior efficiency (per mass unit), selectivity and enhanced activity in catalytic processes. Size and shape of the nanomaterial together with the capping agents govern the surface properties and all the processes happening at the surface, such as catalysis. Different shapes offer great versatility to tune the nanocrystal (NCs) catalytic properties, which are dictated by surface facets. Green synthetic procedures have been developed to obtain pure, monodisperse, citrate-capped Pt and Pd NPs with accurate control on their size and the shape, without the use of polymers, surfactants and organic solvents. For Pd NPs, different geometrical shapes were achieved, such as icosahedrons, cubes, rods and wires while maintaining the thickness of 7 nm and length ranging from 38 to 470 nm (in the case of rods and wires) and the size (in the case of cubes and icosahedron) below 10 nm. These engineered nanomaterials exhibited good biocompatibility along with interesting enzymatic and catalytic properties, due to the absence of sticky molecules, high quality of the surface and the removal of toxic reagents. Moreover, a green synthetic procedure has been developed to obtain ultra-small Pt NCs by combining a strong and a weak reducing agent in aqueous environment in a single reaction vessel in only 10 minutes. NCs with size as low as 2.8 nm and high percentage of {111} surface domains have been achieved. These NCs have been physico-chemically and electrochemically characterized, disclosing significant perspectives for their use as innovative electrocatalysts or nanozymes in portable diagnostics.

Design of Wrist and Forearm Mechanisms for Enhanced Humanoid Dexterity
Creators: name: SHAH, DIVYA HARESH
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: The evolution in humanoid robots, aiming for extensive human-robot co-existence and collaboration, calls for an enhancement in the humanoid manipulation dexterity. Dexterity, in simpler term, is the ability to perform a difficult task quickly and skillfully. When it comes to manipulation dexterity, the emphasis is often on design of anthropomorphic hands. However, this doctoral dissertation endeavors in enhancing the wrist and forearm dexterity from a mechanism design perspective. Light weight design, backdrivability and high payload-to-weight ratio form essential characteristics of a dexterous robotic arm. These objectives can be achieved by reducing inertial loads on the arm by relocating the distal actuators to the proximal links and transmitting power through parallel linkages or tendons. This thesis explores state-of-the-art parallel architectures for wrist implementations. It presents a detailed comparison analyses for promising candidate mechanisms considering their workspace parameters and mechanism isotropy. Based on this study, a two degrees of freedom parallel orientational mechanism is proposed for wrist flexion/extension and radial/ulnar deviation. This mechanism has hemispherical workspace, high range of motion, near to full isotropic behavior and a compact design; the ideal characteristics for a humanoid wrist. Alternatively, for tendon-based transmissions, one of the critical issues is to have appropriate tendon routing so as to avoid any kinematic couplings. To this effect, a novel constant length tendon routing mechanism through an axial joint is also proposed for forearm pronation/supination. This mechanism produces a decoupled full circle rotation
while allowing simultaneous routing for four distal joint tendons. The concept idea, computer-aided design, prototyping and preliminary tests are
demonstrated for both the wrist and forearm mechanisms that aim towards enhancing humanoid dexterity.
Systematic search for extremely metal poor galaxies in the Sloan Digital Sky Survey

description: We carry out a systematic search for extremely metal poor (XMP) galaxies in the spectroscopic sample of Sloan Digital Sky Survey (SDSS) data release 7 (DR7). The XMP candidates are found by classifying all the galaxies according to the form of their spectra in a region 80AA wide around Halpha. Due to the data size, the method requires an automatic classification algorithm. We use k-means. Our systematic search renders 32 galaxies having negligible [NII] lines, as expected in XMP galaxy spectra. Twenty one of them have been previously identified as XMP galaxies in the literature -- the remaining eleven are new. This was established after a thorough bibliographic search that yielded only some 130 galaxies known to have an oxygen metallicity ten times smaller than the Sun (explicitly, with 12+log(O/H) <= 7.65). XMP galaxies are rare; they represent 0.01% of the galaxies with emission lines in SDSS/DR7. Although the final metallicity estimate of all candidates remains pending, strong-line empirical calibrations indicate a metallicity about one-tenth solar, with the oxygen metallicity of the twenty one known targets being 12+log(O/H)= 7.61 +- 0.19. Since the SDSS catalog is limited in apparent magnitude, we have been able to estimate the volume number density of XMP galaxies in the local universe, which turns out to be (1.32 +- 0.23) x 10^-4 Mpc^-3. The XMP galaxies constitute 0.1% of the galaxies in the local volume, or some 0.2% considering only emission line galaxies. All but four of our candidates are blue compact dwarf galaxies (BCDs), and 24 of them have either cometary shape or are formed by chained knots.

Le parole dei vicari di Pietro: osservazioni su alcuni aspetti della retorica papale nella rappresentazione dei longobardi

Year: 2021

description: This research aims at examininig the representation of the Lombards constructed in the papal letters strarting from the arrival of the Lombards in 568 to the end of their regnum in 774. The attention in focused in particular on the occurrences of two latin words, nefas and perfidia and their adjectivizations which are frequently adopted to depict the Lombards in the papal rhetoric. In order to understand better the origins and the application of these terms the first part of the research is devoted to the analysis of the late-antique background in which they were extensively adopted both in their religious and political nuances. A large part of the research is committed to study the representation of the Lombards in the letters and in the works of pope Gregory the Great, trying to soften the traditional interpretation which depicts him as a strong opposer to the Lombards. Later the attention is devoted to the last years of the regnum langobardorum and in particular to the analysis of the rhetorical bases of the political propanganda contained in the letters of pope Stephen II. The last part of the research concentrates on the re-employment of hretorical images adtopted by the papacy between 568 and 774 in other contexts and way after the end of the regnum langobardorum.
Lattice Boltzmann Method: applications to thermal fluid dynamics and energy systems

Publisher: name: Universit� degli studi di Genova
Year: 2021

description: In many energy systems fluids play a fundamental role, and computational simulations are a valuable tool to
study their complex dynamics. The Lattice Boltzmann Method (LBM) is a relatively new numerical method
for computational fluid dynamics, but its applications can be extended to physical phenomena beyond fluid
flows. This thesis presents applications of the LBM to thermal fluid dynamics and energy systems. Specific
applications considered are: application to nuclear reactor engineering problems; thermal fluid dynamic
behavior of a Natural Circulation Loop; nanoparticles gravitational sedimentation; acoustical problems.
The main original contributions derived from this work are: first, the systematic description of the current
status of LBM applications to nuclear reactors problems, including test cases and benchmark simulations;
second, the development and validation of a LBM model for a single-phase natural circulation loop; third,
the development and validation of a LBM model for gravitational sedimentation of nanoparticles, and fourth,
the systematic description of the current status of LBM applications to acoustics, including simulations of
test cases. The development of this thesis was not limited to simulations; experimental studies in parallel
connected natural circulation loops of small inner diameter were conducted, showing the wide applicability
of the one-dimensional theoretical models used to validate the LBM results. Additional contributions derived
from this work: 1. the applicability of the method to study neutron transport and nuclear waste disposal using
porous materials was shown. 2. changes in the thermophysical performance of the natural circulation loop
when the loop reached a non-laminar (transition) regime were found at a Reynolds number lower than the
typical range. 3. variable diffusion and sedimentation parameters were effective to model the experimental
sedimentation curves. In conclusion, this work shows that the LBM is a versatile and powerful computational
tool that can be used beyond the common Computational Fluid Dynamics applications.
title: La question de la pratique de l’archéologie sur le bâti dans le Nord-Pas-de-Calais au sein de l’Inrap
Creators: name: Delmont, Estelle
Publisher: name: Inrap
Year: 2023

description: Depuis 2015, des prescriptions mentionnant plus spécifiquement une approche sur le bâti sont apparues dans certains cahiers des charges du Nord-Pas-de-Calais. L’évolution de la pratique du bâti au sein de l’Inrap, dans ces deux départements, peut être illustrée par la fouille des enceintes modernes du bastion Saint-Maurice de Lille, par le diagnostic de l’enceinte médiévale de Cambrai ainsi que par de petites interventions ponctuelles. La pratique est multiple. De par la nature de la prescription qui prend en compte ou non cette approche, qu’il s’agisse d’un diagnostic ou d’une fouille, mais également de par les connaissances diverses nécessaires à l’appréhension des vestiges. L’intervention en bâti se cantonne parfois à de simples observations, permettant au responsable de l’opération de démêler un séquençage en lien avec ses couches sédimentaires. Parfois une étude des liants, du lapidaire ou des charpentes est requis. La bonne pratique ne peut se cantonner à de simples observations et mérite une étude globale au même titre que celles relevant du sous-sol. D’un point de vue régional, le travail effectué par des collègues attachés à différents services publics alimente le développement de ce champ d’investigation. La collaboration de différents opérateurs au sein de projets collectifs de recherche encourage et fait connaître auprès des services de l’État les résultats que l’on peut attendre d’une part plus grande faite à l’archéologie sur le bâti.
description: Since 2015, specifications that mention more specifically an approach to buildings have appeared in certain specifications in Nord-Pas-de-Calais. The evolution of the practice of building within Inrap, in these two departments, can be illustrated by the excavation of the modern enclosures of the Saint-Maurice bastion in Lille, by the diagnostic of the medieval enclosure of Cambrai as well as by small occasional interventions. The practice is multiple. The nature of the prescription that takes into account or not this approach, whether it is a diagnostic or an excavation, but also by the various knowledge necessary to understand the remains. The intervention in the building is sometimes limited to simple observations, allowing the person in charge of the operation to unravel a sequence in relation to its sedimentary layers. Sometimes a study of the binders, the lapidary or the frameworks is required. Good practice cannot be confined to simple observations and deserves a global study in the same way as those concerning the subsoil. From a regional point of view, the work done by colleagues attached to different public services feeds the development of this field of investigation. The collaboration of different operators within collective research projects encourages and makes known to the State services the results that can be expected from a greater part given to archaeology on the built environment.

description: We present a high-precision infrared radial velocity study of late-type stars using spectra obtained with NIRSPEC at the W. M. Keck Observatory. Radial velocity precisions of 50 m/s are achieved for old field mid-M dwarfs using telluric features for precise wavelength calibration. Using this technique, 20 young stars in the β Pic (age ~12 Myr) and TW Hya (age ~8 Myr) Associations were monitored over several years to search for low mass companions; we also included the chromospherically active field star GJ 873 (EV Lac) in this survey. Based on comparisons with previous optical observations of these young active stars, radial velocity measurements at infrared wavelengths mitigate the radial velocity noise caused by star spots by a factor of ~3. Nevertheless, star spot noise is still the dominant source of measurement error for young stars at 2.3 μm, and limits the precision to ~77 m/s for the slowest rotating stars (v sin i < 6 km/s), increasing to ~168 m/s for rapidly rotating stars (v sin i > 12 km/s). The observations reveal both GJ 3305 and TWA 23 to be single-lined spectroscopic binaries; in the case of GJ 3305, the motion is likely caused by its 0.09" companion, identified after this survey began. The large amplitude, short-timescale variations of TWA 13A are indicative of a hot Jupiter-like companion, but the available data are insufficient to confirm this. We label it as a candidate radial velocity variable. For the remainder of the sample, these observations exclude the presence of any 'hot' (P < 3 days) companions more massive than 8 MJup, and any 'warm' (P < 30 days) companions more massive than 17 MJup, on average. Assuming an edge-on orbit for the edge-on disk system AU Mic, these observations exclude the presence of any hot Jupiters more massive than 1.8 MJup or warm Jupiters more massive than 3.9 MJup.

description: Ziel dieses Beitrags ist es, forschungsethische Prämissen und Problemfelder des qualitativen kommunikationswissenschaftlichen Untersuchens von Interaktion und Kommunikation auf online-medialen Plattformen zu bestimmen. Der Umgang mit zwei Problemfeldern wird für das teilnehmende Beobachten in der deutsch- und englischsprachigen Wikipedia demonstriert. Es wird im ersten Problemfeld betrachtet, welche Konsequenzen die (bedingte) Öffentlichkeit von selbst-, fremd- oder systemgenerierten Informationen für das Gewährleisten von Anonymität hat. Im zweiten Problemfeld wird diskutiert, welche Konsequenzen die Anonymität auf Plattformen für das Absichern von informierter Zustimmung mit sich bringt.
description: The paper examines the ethical premises and trade-offs inherent to the qualitative study of communication and interaction within online platforms, using the example of a participant observation of the German and English versions of the user-generated Wikipedia. Conceptually, the first area of ethical concern is developed with regard to the varying publicness of information produced by users about users, and through digital technology and the need to assure the anonymity of research subjects. The second area of ethical concern is then established in terms of user anonymity and its impact on warranting informed consent. Turning to its case study, the paper explains how these two areas of concern informed the participant observation of Wikipedians and their collaborative work.

description: Many cytoskeletal biopolymers are "active," consuming energy in large quantities. In this Letter, we identify a fundamental difference between active polymers and passive, equilibrium polymers: for equal mean lengths, active polymers can reorganize faster than equilibrium polymers. We show that equilibrium polymers are intrinsically limited to linear scaling between mean lifetime and mean length, MFPT ~ , by analogy to 1-d Potts models. By contrast, we present a simple active-polymer model that improves upon this scaling, such that MFPT ~ ^{1/2}. Since to be biologically useful, structural biopolymers must typically be many monomers long, yet respond dynamically to the needs of the cell, the difference in reorganization kinetics may help to justify active polymers' greater energy cost.

description: Der Erfahrungsaustausch zwischen Patienten findet verstärkt über Arztbewertungsportale statt. Dabei ermöglicht die Anonymität des Netzes ein weitestgehend ehrliches Beschwerdeverhalten, von dem das sensible Arzt-Patienten-Vertrauensverhältnis unbeschädigt bleibt. Im Rahmen des vorliegenden Beitrags wurden anonyme Arztbewertungen im Web 2.0 automatisiert ausgewertet, um Einflussfaktoren auf das Beschwerdeverhalten deutscher Patienten zu bestimmen und in der Gesellschaft vermeintlich etablierte "Patienten-Mythen" aufzuklären. Die Aufdeckung von Irrtümern und Zufriedenheitsindikatoren soll längerfristig dazu dienen, Patientenäußerungen differenzierter zu interpretieren und somit zu einer nachhaltigen Verbesserung der Arzt-Patienten-Beziehung beizutragen.

description: Digitale Methoden haben in den letzten Jahren nicht nur in die Sozial- und Geisteswissenschaften Einzug gehalten. Auch der Journalismus hat seine Verfahren digitalisiert und seine Recherchepraktiken sowie seine Darstellungsformen entsprechend angepasst. Immer öfter bedienen sich JournalistInnen für ihre Berichterstattung des Werkzeugkastens der digitalen Methoden. Am deutlichsten zeigt sich das am Datenjournalismus, der seit einem Jahrzehnt einen enormen Aufschwung erfahren hat. Dieser Beitrag beleuchtet digitale Methoden im Datenjournalismus. Zu diesem Zweck werden hier zunächst aus den Science and Technology Studies und der Digital-Methods-Forschung heraus die Grundzüge einer datenjournalistischen Methodologie entwickelt. Auf Grundlage von Redaktionsbesuchen und elf semistrukturierten Interviews mit PraktikerInnen werden im Anschluss konkrete Arbeitsabläufe und Akteure in datenjournalistischen Methoden beschrieben. Es wird erläutert, wie datenjournalistische Kollaborationen im Newsroom funktionieren, wie sich dort Routinen etablieren und welche Technologien dabei vermitteln. Abschließend werden Empfehlungen zur Weiterentwicklung digitaler Methoden in der Kommunikationswissenschaft und im Datenjournalismus formuliert.
description: While in recent years digital methods have become increasingly central to the social sciences and the humanities, they have also impacted journalism, effecting an evolution in its procedures, research practices, and formats. More and more journalists employ a toolbox of digital methods, a trend most evident in data journalism, which has undergone a tremendous popularization in the past decade. This article examines the digital methods of data journalism. It consists of two parts: the first is an outline for a data journalistic methodology, based on works from science and technology studies and digital methods research. The second part describes the specific workflows and actors central to data journalistic methods, insights grounded in visits to newsrooms and eleven semi-structured interviews. The article explains how collaborations in data journalism work, how routines are established, and how technologies mediate these processes. The findings then provide the basis for recommendations concerning the continued development of digital methods within communication research and data journalism.

An Analysis of the Concept of Consciousness
Creators: name: CASTRO MARTIN, LUIS GUILLERMO

description: The aim of this research is to introduce an interpretation of the concept of consciousness that is metaphysically compatible with most contemporary theories of consciousness, insofar as it is intended to fix the conceptual level to which the study of consciousness belongs. In the first chapter, I analyze different uses of the terms ?awareness? and ?consciousness? and three approaches to the concept of consciousness that can be drawn from three popular kinds of
theories of consciousness. My goal is to show that those approaches are based on the identification of three discernible features of conscious states, namely, intentionality, reflexivity and phenomenality. In the second chapter, I introduce an interpretation of the concept of consciousness where the above features are characterized as components of the
concept, unifying them into a single conceptual space. Such interpretation allows me to explore how the conceptual space can be adjusted to build models of consciousness. In the third chapter, I argue that conscious states are internal states that are described in terms of the components of the concept of consciousness and their relations. In the fourth chapter, I show how my view can be implemented to theorize about non-human consciousness by analyzing two kinds of non-human systems, namely, dolphins and bees.
