description: Most cancer deaths are due to metastases. Markers of epithelial-mesenchymal transition (EMT) measured in primary tumor cancer cells could be helpful to assess patient risk of metastatic disease, even among those otherwise diagnosed with local disease. Previous studies of EMT markers and patient outcomes used inconsistent methods and did not compare the clinical impact of different expression cut points for the same marker. Using digital image analysis, we measured the EMT markers Snail and E-cadherin in primary tumor specimens from 190 subjects in tissue microarrays from a population-based prospective cohort of colorectal cancer patients and estimated their associations with time-to-death. After measuring continuous marker expression data, we performed a systematic search for the cut point for each marker with the best model fit between dichotomous marker expression and time-to-death. We also assessed the potential clinical impact of different cut points for the same marker. After dichotomizing expression status at the statistically-optimal cut point, we found that Snail expression was not associated with time-to-death. When measured as a weighted average of tumor cores, low E-cadherin expression was associated with a greater risk of dying within 5 years of surgery than high expression (risk difference = 33 %, 95 % confidence interval 3–62 %). Identifying a clinically-optimal cut point for an EMT marker requires trade-offs between strength and precision of the association with patient outcomes, as well as consideration of the number of patients whose treatments might change based on using the marker at a given cut point.

description: The article illustrates selected results of an exploratory research study on ‘GAS movement’ coordinated by the Solidarity Economy Network in Marche Region, Italy. The GAS experience proves to revolve substantially around food purchasing groups practice. Therefore, the research aimed at investigating the economic and eco-logical determinants characterising the world of critical food consumption. Qualitative and quantitative data have been analysed from a socio-economic and ecological point of view, providing an insight on different issues concerning the framework of the solidarity economy and possible further developments. The ecological performance of a “critical food consume” in comparison with a “conventional one” was assessed using the Material Input Per Service unit (MIPS) concept.

description: Claim paragraph (from the sourcing sheet): All projects target a single inferential statistical test that supports a statement from the abstract of the original paper. The SCORE team selected the claim that as a measure of social preference, the amount of money sent by Player A to Player B in a trust game is inversely related to participation in a laboratory experiment (Statement 2), which reflects "…we also find that people who sent less in a trust game were more likely to participate in a laboratory experiment,…" (Statement 1), as found in the paper's abstract. The claim is tested by a linear probability model with a binary experiment participation outcome and the amount sent in dollars as an independent variable. The model also included a set of control variables (see model specification on page 377) (Statement 3), which resulted in a statistically significant association (p < .01) between the amount a player sent and participation in a laboratory experiment. The marginal effect indicates that for every additional $10 sent during the experiment, a student was, in absolute terms, 4.3 percent less likely to select into the lab (Statement 4). The focal test in the original paper is: a statistically significant association (p < .01) between the amount a player sent and participation in a laboratory experiment. The marginal effect indicates that for every additional $10 sent during the experiment, a student was, in absolute terms, 4.3 percent less likely to select into the lab.

description: We selected the claim that there is a nonmonotonic relationship between the relative political importance of competing interests and the likelihood of violence during reorganization, with violence demonstrating an inverted U-shape relationship as a function of the ratio of antistatehood to prostatehood political importance (Statement 2). This reflects the following statement from the paper's abstract: "I show that representation in the ruling party conditioned the likelihood of a violent statehood movement...These results call into question the search for a monotonic relationship between grievances and violence" (Statement 1). The claim is tested with data on incidents of reorganization-related violence that resulted in injuries or deaths between January 26, 1950, when the Indian constitution came into effect, and November 1, 1956, when the State Reorganisation Act came into effect. The author estimates a multinomial logistic regression of reorgnization outcomes, with a dependent variable taking on three levels (an enclave where statehood was achieved peacefully; violence occurred possibly followed by statehood; no violence and no statehood occurred [omitted category]). The predictors include linear and squared terms for relative political importance -- measured as the ratio of Congress representation of opponents of statehood to the Congress representation of proponents (logged) -- as well as additional covariates specified in Model 1 of Table 5. In conjunction with the positive coefficient on logged relative political importance as a predictor of the violence outcome, the hypothesized non-monotonic relationship is tested with the coefficient on the squared term for logged relative political importance (Statement 3). In conjunction with the positive and significant coefficient on logged relative political importance as a predictor of the violence outcome, the author finds a negative and significant coefficient on the squared term for logged relative political importance (coefficient = -0.341, SE clustered by state = 0.104, p < 0.10) (Statement 4). The focal test in the original paper is: a negative and significant coefficient on the squared term for logged relative political importance (coefficient = -0.341, SE clustered by state = 0.104, p < 0.10)

description: Multiple p- and s-polarized compound surface plasmon-polariton (SPP) waves at a fixed frequency can be guided by a structure consisting of a metal layer sandwiched between a homogeneous isotropic dielectric (HID) material and a periodic multilayered isotropic dielectric (PMLID) material. For any thickness of the metal layer, at least one compound SPP wave must exist. It possesses the p-polarization state, is strongly bound to the metal/HID interface when the metal thickness is large but to both metal/dielectric interfaces when the metal thickness is small. When the metal layer vanishes, this compound SPP wave transmutes into a Tamm wave. Additional compound SPP waves exist, depending on the thickness of the metal layer, the relative permittivity of the HID material, and the period and the composition of the PMLID material. Some of these are p polarized, the others being s polarized. All of them differ in phase speed, attenuation rate, and field profile, even though all are excitable at the same frequency. The multiplicity and the dependence of the number of compound SPP waves on the relative permittivity of the HID material when the metal layer is thin could be useful for optical sensing applications.

description: Malignant pleural effusion (MPE) is a poor prognostic sign for cancer patients, whereas the functional condition of MPE CD8+ T cells is unknown. Intracavitary immunotherapy with interleukin (IL)‐2 has been proven effective in controlling MPE. To elucidate the underlying mechanism, 35 lung cancer (LC) patients with MPE and 12 healthy donors were included in this study. For the IL‐2 therapy experiments, after draining partial MPE, we treated 14 patients by administrating IL‐2 (3 or 5 × 106 U in 50 ml saline) into the thoracic cavity. Before and after IL‐2 treatment (40‐48 h), the MPE and peripheral blood (PB) were obtained from the subjects. PB from healthy volunteers was collected as control. The expression of programmed cell death 1 (PD‐1), granzyme B (GzmB), interferon (IFN)‐γ and the proliferation were analysed in CD8+ T cells from MPE and PB. The CD8+ T cells in the MPE of LC patients showed lowest GzmB, IFN‐γ and proliferation but highest PD‐1 expression, compared with that in PB of LC patients and healthy donors. IL‐2 treatment reduced the expression of PD‐1, increased the expression of GzmB and IFN‐γ and enhanced the proliferation of CD8+ T cells in MPE. In addition, IL‐2 treatment reduced carcino‐embryonic antigen (CEA) level in MPE. These results indicate that MPE CD8+ T cells exhibit exhaustion phenotype which can be reversed by IL‐2 therapy.

description: The currently most effective approach for reduction of friction and wear in cold forging is the application of lubricants. Scope of the present study is the design and realization of a surface modification concept for form ing tools to enable the cold extrusion of aluminum in absence of lubricants. By quantum-mechanical guided design of wear resisting layers with reduced interaction, minimization of adhesion as the main wear mechanism is aspired. Through smoothing of roughness peaks and topography homogenization the laser assisted surface modification of the tools systematically aims at minimization of abrasive wear and thus less wear particles that act as nuclei for adhesive processes. Evaluation of the developed structures and layers is carried out on a newly designed torsion-tribometer, which enables the free scaling of contact stress and slide path combined with a certain amount of surface expansion. The report first gives an insight into the current state of the art, analyses the load case during cold extrusion and derives suitable tribological experiments for the characterization of adequate surface modifications. Subsequently, laser polishing and structuring processes are presented and, based on a quantum mechanical calculation of the interaction between tool and workpiece (aluminum), a possible solution concept by the use of self-assembling monolayers is presented. Finally, the methods are combined and their influence on adhesive wear is highlighted in tribological tests.

description: Von den naturwissenschaftlichen Fächern wird Biologie am häufi gsten bilingual unterrichtet. In diesem Fall ist das Fach Biologie von dem bekannten Dilemma betroffen, dass die teilnehmenden Schüler gelegentlich die Unterrichtsinhalte kognitiv besser bewältigen, als sie sich (fremd-)sprachlich artikulieren können. Auch aus diesem Grund bedarf es besonderer Maßnahmen, um eine inhaltliche und sprachliche Festigung der Unterrichtsinhalte sicher zu stellen. Der Beitrag diskutiert den Stellenwert dieser besonderen Sicherungsmethoden und nennt Kriterien zu ihrer Auswahl. Praxiserprobte und bewährte Sicherungsmethoden für den bilingualen Biologieunterricht werden vorgestellt und hinsichtlich ihrer Kriterienprofile miteinander verglichen.

description: The prototype of the NIKA2 camera, NIKA, is an instrument operating at the IRAM 30-m telescope, which can observe simultaneously at 150 and 260GHz. One of the main goals of NIKA2 is to measure the pressure distribution in galaxy clusters at high resolution using the thermal SZ (tSZ) effect. Such observations have already proved to be an excellent probe of cluster pressure distributions even at high redshifts. However, an important fraction of clusters host submm and/or radio point sources, which can significantly affect the reconstructed signal. Here we report on <20" resolution observations at 150 and 260GHz of the cluster MACSJ1424, which hosts both radio and submm point sources. We examine the morphology of the tSZ signal and compare it to other datasets. The NIKA data are combined with Herschel satellite data to study the SED of the submm point source contaminants. We then perform a joint reconstruction of the intracluster medium (ICM) electronic pressure and density by combining NIKA, Planck, XMM-Newton, and Chandra data, focusing on the impact of the radio and submm sources on the reconstructed pressure profile. We find that large-scale pressure distribution is unaffected by the point sources because of the resolved nature of the NIKA observations. The reconstructed pressure in the inner region is slightly higher when the contribution of point sources are removed. We show that it is not possible to set strong constraints on the central pressure distribution without accurately removing these contaminants. The comparison with X-ray only data shows good agreement for the pressure, temperature, and entropy profiles, which all indicate that MACSJ1424 is a dynamically relaxed cool core system. The present observations illustrate the possibility of measuring these quantities with a relatively small integration time, even at high redshift and without X-ray spectroscopy.

description: We selected the claim that extra family income has a modest, but encouraging, causal effect for children growing up in poor families. The IV results indicate that current income has significant effects on a child’s math and reading test scores. This reflects the following statement from the paper’s abstract: “Our baseline estimates imply that a $1,000 increase in income raises combined math and reading test scores by 6 percent of a standard deviation in the short run.” Table 3 reports baseline IV estimates for the combined math-reading achievement measure. The dependent variable is “Combined math and reading” and the focal independent variable is “Current income”. The portion in Table 3 that’s selected is Column 1. The results in column 1 imply that a $1,000 increase in family income raises math-reading achievement by 6 percent of a standard deviation, a modest effect. (Coefficient for “Current Income” is 0.0610 with standard errors clustered at the family level of 0.0231, significant at the 5 percent level.) The focal test in the original paper is: (Coefficient for “Current Income” is 0.0610 with standard errors clustered at the family level of 0.0231, significant at the 5 percent level.)

description: Der Frontalunterricht, die bekannteste Unterrichtsmethode, wird durch die dominierende, organisierende Lehrerrolle geprägt. Er stellt eine lehrerzentrierte Unterrichtsform dar, dem das selbstständige Lernen mit Handlungs- und Schülerorientierung gegenübersteht. Selbstständiges Lernen ist immer im Zusammenhang von Selbstbestimmung, Selbstverantwortung und Selbstkontrolle zu sehen. Das selbstständige Lernen kann in verschiedenen Unterrichtsformen praktiziert werden. In der vorliegenden Arbeit werden die Unterrichtsmethoden Freiarbeit und Frontalunterricht gegenübergestellt. Zum Thema Pfl anzen im Biologieunterricht wurden jeweils zwei fünfte Klassen an zwei Gymnasien über einen Zeitraum von vier Schulstunden mit jeweils einer der Unterrichtsmethoden unterrichtet. Die Untersuchung zeigt, dass die Freiarbeit in den meisten Fällen wesentlich bessere Lernerfolge bei den Schülern bewirkt als der Frontalunterricht.

description: Here, we investigate the growth of matter density perturbations as well as the generalized second law (GSL) of thermodynamics in the framework of $f(R)$-gravity. We consider a spatially flat FRW universe filled with the pressureless matter and radiation which is enclosed by the dynamical apparent horizon with the Hawking temperature. For some viable $f(R)$ models containing the Starobinsky, Hu-Sawicki, Exponential, Tsujikawa and AB models, we first explore numerically the evolution of some cosmological parameters like the Hubble parameter, the Ricci scalar, the deceleration parameter, the density parameters and the equation of state parameters. Then, we examine the validity of GSL and obtain the growth factor of structure formation. We find that for the aforementioned models, the GSL is satisfied from the early times to the present epoch. But in the farther future, the GSL for the all models is violated. Our numerical results also show that for the all models, the growth factor for larger structures like the $Λ$CDM model fit the data very well.

description: We conjecture an embedding operator which assigns, to any 2n+1 hermitian matrices, a 2n-dimensional hypersurface in flat (2n + 1)-dimensional Euclidean space. This corresponds to precisely defining a fuzzy D(2n)-brane corresponding to N D0-branes. Points on the emergent hypersurface correspond to zero eigenstates of the embedding operator, which have an interpretation as coherent states underlying the emergent noncommutative geometry. Using this correspondence, all physical properties of the emergent D(2n)-brane can be computed. We apply our conjecture to noncommutative flat and spherical spaces. As a by-product, we obtain a construction of a rotationally symmetric flat noncommutative space in 4 dimensions.

description: We present and test chemical models for three-dimensional hydrodynamical simulations of galaxies. We explore the effect of changing key parameters such as metallicity, radiation and non-equilibrium versus equilibrium metal cooling approximations on the transition between the gas phases in the interstellar medium. The microphysics is modelled by employing the public chemistry package KROME and the chemical networks have been tested to work in a wide range of densities and temperatures. We describe a simple H/He network following the formation of H$_2$, and a more sophisticated network which includes metals. Photochemistry, thermal processes, and different prescriptions for the H$_2$ catalysis on dust are presented and tested within a one-zone framework. The resulting network is made publicly available on the KROME webpage. We find that employing an accurate treatment of the dust-related processes induces a faster HI--H$_2$ transition. In addition, we show when the equilibrium assumption for metal cooling holds, and how a non-equilibrium approach affects the thermal evolution of the gas and the HII--HI transition. These models can be employed in any hydrodynamical code via an interface to KROME and can be applied to different problems including isolated galaxies, cosmological simulations of galaxy formation and evolution, supernova explosions in molecular clouds, and the modelling of star-forming regions. The metal network can be used for a comparison with observational data of CII 158 $μ$m emission both for high-redshift as well as for local galaxies.

description: Das Modellverständnis als Element von Modellkompetenz wird durch folgende Aspekte strukturiert: die Definition des Begriffs „Modell“, Kriterien für Modelle, Zweck von Modellen, Veränderbarkeit von Modellen und multiple Modelle. Schüleraussagen zu diesen Kriterien werden in Anlehnung an CAREY et al. (1989), DRIVER et al. (1996) und GÜNTHER et al. (2004) qualitativ drei Levels zugeordnet. 70 Schülern der neunten Jahrgangsstufe an zwei Berliner Gymnasien wurden im Biologieunterricht offene Fragen zu ihrem Modellverständnis zur schriftlichen Bearbeitung vorgelegt. Die Antworten wurden nach der qualitativen Inhaltsanalyse (MAYRING 2003) ausgewertet. Ein Schwerpunkt in den erfassten Schülervorstellungen sind die deskriptiven Aspekte von Modellen, das heißt sie werden vorwiegend in ihrer Anschauungsfunktion wahrgenommen. Die Rolle von Modellen im wissenschaftlichen Erkenntnisprozess wurde in der Regel nicht erkannt. Darüber hinaus waren die Vorstellungen der Schüler bezogen auf die theoretischen Aspekte von Modellen häufi g inkonsistent. Im Rahmen der vorliegenden Untersuchung stellt sich demnach die Struktur des Modellverständnisses der Schüler als eher mosaikartig dar und weist auf ein kompartimentalisiertes Wissen über Modelle hin.

description: Die Untersuchung fand 2006 in 5 Klassen der vierten Jahrgangsstufe in ländlicher Umgebung statt. Von den befragten 111 Schülern waren 45 Jungen und 66 Mädchen. 70 der 111 Schüler hatten bereits Sexualkundeunterricht. Dieser führte nach dem Ergebnis dieser Untersuchung nicht zu einem umfassenden Wissensstand. Im Rahmen der Lehrerausbildung in Niedersachsen ist eine Vorbereitung auf den Sexualkundeunterricht nicht verpflichtend und das, obwohl die Pubertät im Vergleich zu den vorhergehenden Generationen früher einsetzt. Eine qualitativ hochwertige sexuelle Aufklärung scheint daher für alle Kinder vor Einsetzen der Pubertät sinnvoll.

description: Einblicke in die aktuelle Aufgabenkultur, speziell die Verwendung von Aufgaben in Prüfungsphasen, gibt es für den Biologieunterricht nur sehr wenige. Dieser Beitrag begründet die Notwendigkeit, an diesem Forschungsdefizit anzusetzen, und stellt eine Untersuchung vor, in deren Zentrum die Analyse von insgesamt 600 derzeit eingesetzten Testaufgaben stand. Als Analysekriterien wurden hier zum einen die Kennzeichnung formaler Aufgabentypen sowie auch die Bestimmung kognitiver Anforderungsniveaus herangezogen. Zusätzlich wurden die Lehrkräfte, die die untersuchten Aufgaben verwenden, schriftlich über ihre Prüfungsaufgabengestaltung befragt. Dabei wurde deutlich, dass Aufgaben, die eine Beantwortung in kurzer textlicher Form erfordern, bevorzugt werden, sowie dass sich ein hoher Anteil der gestellten Aufgaben auf den Anforderungsbereich des Wissens beschränkt. Darüber hinaus zeigte sich kein Zusammenhang zwischen den Ergebnissen der Aufgabenanalyse im Hinblick auf die abgeprüften kognitiven Anforderungsbereiche und den diesbezüglichen Selbsteinschätzungen der Lehrkräfte.

description: Since 2010, the Yale physics department has offered a novel calculus-based introductory physics for the life science (IPLS) sequence, that re-imagines the IPLS syllabus to include a selection of biologically and medically relevant topics, that are highly meaningful to its audience of biological science and premedical undergraduates. The first semester, in particular, differs considerably from traditional first-semester introductory physics. Here, we highlight the novel aspects of Yale's first-semester course, and describe student feedback about the course, including a comparison between how students evaluate the course and how they evaluate courses with a traditional syllabus, and how students' perceptions of the relevance of physics to biology and medicine are affected by having taken the course.

description: Der Einsatz originaler Objekte im Biologieunterricht wird zwar vielfach gefordert, aber bislang konnten nur in wenigen empirischen Untersuchungen die positiven Wirkungen theoriegeleitet belegt werden. In der vorliegenden Studie gehen wir davon aus, dass 1. Prozessmerkmale konstruktivistisch orientierten Lernens und 2. motivationale Anreizbedingungen durch den unterrichtlichen Einsatz lebender Eurasischer Zwergmäuse (Micromys minutus PALLAS 1778) beeinflusst werden. Untersucht wurden Wissenszuwachs, Motivation und Schülerhaltungswunsch nach einer Unterrichtssequenz zur Lebensweise Eurasischer Zwergmäuse an 127 Schülern der fünften Jahrgangsstufe. Die drei Treatmentgruppen unterscheiden sich wie folgt: 1. Die Sequenz wird ausschließlich unter Verwendung von stellvertretenden Repräsentationsformen bearbeitet. 2. Der Unterricht wird unter Verwendung originaler Objekte (lebende Eurasische Zwergmäuse) gestaltet. 3. Die Schüler werden unter Verwendung originaler Objekte unterrichtet und zusätzlich werden Zwergmäuse für einen Zeitraum von sechs Wochen im Klassenraum gehalten. Die Befunde weise für die kognitive wie für die motivationale Ebene auf positive Wirkungen des Einsatzes der originalen Objekte hin. Interessanterweise zeigen Schüler, die Zwergmäuse in der Klasse halten konnten, eine weit geringere Tendenz, Zwergmäuse als Haustiere halten zu wollen, als Schüler der Treatmentgruppe mit punktuellem unterrichtlichen Einsatz lebender Zwergmäuse.

description: In unserer vergleichenden Querschnittstudie haben wir die Vorstellungen zum pflanzlichen Entwicklungszyklus von Schülerinnen und Schülern unterschiedlicher Schulstufen (Jgst. 1, 6, 8) sowie von Studierenden erhoben. Im Rahmen leitfadenstrukturierter Einzelinterviews sollten unterschiedliche Entwicklungsstadien einer einjährigen Blütenpflanze geordnet und das Vorgehen begründet werden. Zusätzlich wurden ergänzende Fragen zur Herkunft von Pflanzen und Samen gestellt. Die Ergebnisse der Studie zeigen, dass die meisten Probanden Schwierigkeiten hatten, die pflanzliche Entwicklung als Zyklus bzw. Spirale zu verstehen. Dies ließ sich nicht nur an der gestellten Reihenfolge, sondern vor allem an den Begründungen für die gewählte Reihe erkennen. Die Mehrheit der Untersuchten – auch der Erwachsenen – verfügt demnach nicht über ein tragfähiges Konzept zum pflanzlichen Entwicklungszyklus. Einen entscheidenden Einfluss zur Entwicklung eines tragfähigen Konzepts hat die eigene Vorerfahrung mit Säen von Samen: Es besteht ein hochsignifikanter Zusammenhang zwischen eigenen Erfahrungen mit dem Aussäen und dem Stellen der Reihe. Dies spricht für einen erfahrungsbasierten Ansatz als Ausgangspunkt für erfolgreichen Unterricht.

description: We consider the Einstein-Maxwell-fluid constraint equations, and make use of the conformal method to construct and parametrize constant-mean-curvature hyperboloidal initial data sets that satisfy the shear-free condition. This condition is known to be necessary in order that a spacetime development admit a regular conformal boundary at future null infinity. We work with initial data sets in a variety of regularity classes, primarily considering those data sets whose geometries are weakly asymptotically hyperbolic, as defined in [arXiv:1506.03399]. These metrics are $C^{1,1}$ conformally compact, but not necessarily $C^2$ conformally compact. In order to ensure that the data sets we construct are indeed shear-free, we make use of the conformally covariant traceless Hessian introduced in [arXiv:1506.03399]. We furthermore construct a class of initial data sets with weakly asymptotically hyerbolic metrics that may be only $C^{0,1}$ conformally compact; these data sets are insufficiently regular to make sense of the shear-free condition.

description: ABSTRACT Pertussis is a severe respiratory disease caused by infection with the bacterial pathogen Bordetella pertussis . The disease affects individuals of all ages but is particularly severe and sometimes fatal in unvaccinated young infants. Other Bordetella species cause diseases in humans, animals, and birds. Scientific, clinical, public health, vaccine company, and regulatory agency experts on these pathogens and diseases gathered in Buenos Aires, Argentina from 5 to 8 April 2016 for the 11th International Bordetella Symposium to discuss recent advances in our understanding of the biology of these organisms, the diseases they cause, and the development of new vaccines and other strategies to prevent these diseases. Highlights of the meeting included pertussis epidemiology in developing nations, genomic analysis of Bordetella biology and evolution, regulation of virulence factor expression, new model systems to study Bordetella biology and disease, effects of different vaccines on immune responses, maternal immunization as a strategy to prevent newborn disease, and novel vaccine development for pertussis. In addition, the group approved the formation of an International Bordetella Society to promote research and information exchange on bordetellae and to organize future meetings. A new Bordetella.org website will also be developed to facilitate these goals.
A study of decoherence effects in the Stern-Gerlach experiment using matrix Wigner functions

description: We analyze the Stern-Gerlach experiment in phase space with the help of the matrix Wigner function, which includes the spin degree of freedom. Such analysis allows for an intuitive visualization of the quantum dynamics of the apparatus. We include the interaction with the environment, as described by the Caldeira-Leggett model. The diagonal terms of the matrix provide us with information about the two components of the state, that arise from interaction with the magnetic field gradient. In particular, from the marginals of these components, we obtain an analytical formula for the position and momentum probability distributions in presence of decoherence, that show a diffusive behavior for large values of the decoherence parameter. These features limit the dynamics of the present model. We also observe the decay of the non-diagonal terms with time, and use this fact to quantify the amount of decoherence, from the norm of those terms in phase space. From here, we can define a decoherence time scale, which differs from previous results that make use of the same model.
