Search for a Vector-like Quark with Charge 2/3 in t + Z Events from pp Collisions at sqrt(s) = 7 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for pair-produced heavy vector-like charge-2/3 quarks, T, in pp collisions at a center-of-mass energy of 7 TeV, is performed with the CMS detector at the LHC. Events consistent with the flavor-changing-neutral-current decay of a T quark to a top quark and a Z boson are selected by requiring two leptons from the Z-boson decay, as well as an additional isolated charged lepton. In a data sample corresponding to an integrated luminosity of 1.14 inverse femtobarns, the number of observed events is found to be consistent with the standard model background prediction. Assuming a branching fraction of 100% for the decay T to tZ, a T quark with a mass less than 475 GeV/c^2 is excluded at the 95% confidence level.

description: We present an analysis of the z ~ 0 morphology-environment relation for 911 bright (M_B < -19) galaxies, matching classical RC3 morphologies to the SDSS-based group catalog of Yang et al. We study how the relative fractions of spirals, lenticulars, and ellipticals depend on halo mass over a range of 10^11.7-10^14.8 h^-1 Msol. We pay particular attention to how morphology relates to central (most massive) vs satellite galaxy status. The fraction of galaxies which are elliptical is a strong function of stellar mass; it is also a strong function of halo mass, but only for central galaxies. We interpret this in a scenario where elliptical galaxies are formed, probably via mergers, as central galaxies within their halos; satellite ellipticals are previously central galaxies accreted onto larger halos. The overall fraction of S0 galaxies increases strongly with halo mass, from ~10% to ~70%. We find striking differences between the central and satellites: 20+/-2% of central M_* > 10^10.5 Msol galaxies are S0 regardless of halo mass, but satellite S0 galaxies are only found in massive (> 10^13 h^-1 Msol) halos, where they are 69+/-4% of the M_* > 10^10.5 Msol satellite population. This suggests two channels for S0 formation: one for central galaxies, and another which transforms lower mass (M_*

In-situ Accretion of Hydrogen-Rich Atmospheres on Short-Period Super-Earths: Implications for the Kepler-11 Planets
Creators: name: Ikoma, Masahiro

Year: 2012

subject: FOS: Physical sciences

description: Motivated by recent discoveries of low-density super-Earths with short orbital periods, we have investigated in-situ accretion of H-He atmospheres on rocky bodies embedded in dissipating warm disks, by simulating quasi-static evolution of atmospheres that connect to the ambient disk. We have found that the atmospheric evolution has two distinctly different outcomes, depending on the rocky body's mass: While the atmospheres on massive rocky bodies undergo runaway disk-gas accretion, those on light rocky bodies undergo significant erosion during disk dispersal. In the atmospheric erosion, the heat content of the rocky body that was previously neglected plays an important role. We have also realized that the atmospheric mass is rather sensitive to disk temperature in the mass range of interest in this study. Our theory is applied to recently-detected super-Earths orbiting Kepler-11 to examine the possibility that the planets are rock-dominated ones with relatively thick H-He atmospheres. The application suggests that the in-situ formation of the relatively thick H-He atmospheres inferred by structure modeling is possible only under restricted conditions; namely, relatively slow disk dissipation and/or cool environments. This study demonstrates that low-density super-Earths provide important clues to understanding of planetary accretion and disk evolution.

description: In time for the first tests on LHC data we introduce a set of improvements and tests of purely kinematic top tagging algorithms. First, we show how different jet algorithms can be used for different transverse momentum regimes. Combining pruning and filtering in the reconstruction can enhance the signal over background ratio significantly, while larger jet radii only give minor improvements. Finally, bottom tagging can be added to the top tagger, but at least for the HEPTopTagger does not improve the kinematic selection algorithm.

description: We consider pair production and decay of fundamental unstable particles in the framework of a modified perturbation theory (MPT), which treats resonant contributions of unstable particles in the sense of distributions. The cross-sections for the top-quark pair production and for the $W$-boson pair production in $e^{+}e^{-}$ annihilation are calculated within the NNLO in models that admit exact solutions. In both cases an excellent convergence of the MPT is detected at the energies close to and above the maximum of the cross section. In the case of $W$-boson pair production a precision of the description at the ILC energies is ensured at the level of one per-mille or higher.

Year: 2012

description: The first theorem states that all flat space-time gravitational theories must have a Lagrangian with a first term that is an homogeneous (degree-I) function of the 4-velocity $u^i$, plus a functional of $η_{ij}u^i u^j$. The second theorem states that all gravitational theories that satisfy the strong equivalence principle have a Lagrangian with a first term $g_{ij}(x)u^i u^j$ plus an irrelevant term. In both cases the theories must issue from a unique variational principle. Therefore, under this condition it is impossible to find a flat space-time theory that satisfies the strong equivalence principle.

description: Introduction/ Background
Biobanks and their operators are gaining popularity. However, they face a range of growing challenges. Many of these biobanks used to be smaller and midsized collections of data and samples, but are now being developed into centralized networks within clinics and consortia. These large biobanks require the integration of as many sources of information as possible, including imaging data in addition to any relevant structured data. This is especially the case in the field of virtual microscopy. Data collection is increasingly being orchestrated by workflow based systems and must eventually be incorporated entirely into rule based IT-processes.
Aims
In order to achieve this goal, the Charité University Medicine Berlin, VMscope GmbH, and Kairos GmbH formed a consortium in the framework of the joint project, “Biobanking 3.0”, which is funded by the German Federal Ministry for Education and Research (BMBF). Furthermore, after this successful project, a second KMU funded project called POST (Patient-centric Open Multi Center Study Tool) will begin in the autumn of 2015 to expand the data integration to pathology information systems in a standardized manner.
Methods
One of the project goals is to use an IT-platform with an integrated workflow-engine to orchestrate all necessary processes and document all findings. Defined SOPs during sample extraction and information acquisition can be executed, and all result data can be made available to local research groups as well as project partners.
Results
Thus, the platform pursues the research approach of personalized medicine, which requires exact controlling of therapy cycles in a logical and chronological order.

Experiential environmental education : looking at the socio-cultural variables that affect attitudes and behaviours following a marine conservation program
Creators: name: Kennedy, Jennifer Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: This study explores the impacts of an experiential, environmental school program (Intertidal Marine Biology) at the Vancouver Aquarium Marine Science Centre that is linked to the British Columbia Grade 11 Biology Curriculum. Little is known about the socio-cultural characteristics of participants that may influence their behaviours about, and attitudes towards, marine environmental issues after participation. This is reflected across the field of informal environmental education, and while this study is focussed on a unique program, the results offer insight into the field of experiential, informal, and environmental education in general. This research is based on a two-stage, mixed methods approach. The first stage comprised of an assessment of students’ environmental attitudes and behaviours using a specially developed questionnaire instrument that was administered to 129 students from three different schools. The second stage involved face-to-face student interviews with a sub-sample of stage 1 students. The variables that were examined included year of participation, school, gender, ethnicity, birthplace, parent’s birthplace, hobbies, museum visitation, Ocean Wise use, most enjoyable component, and least enjoyable component of the program. These were broadly conceived to be socio-cultural variables that may have an impact on a student’s attitudes and behaviours following engagement in the program. The results of this study were based on these independent socio-cultural variables, which were tested against the dependent measures of attitude and behaviour. Many of the socio-cultural variables were demonstrated to be statistically significant in influencing students’ perceptions of their own attitudes and behaviours after the program. Students consistently showed an increase in their positive environmental attitudes and behaviours after participation in the program. When measured against the socio-cultural variables, student attitudes and behaviours were influenced by factors including school, gender, birthplace, parent’s birthplace, parent’s birth country, favourite hobbies, and museum visitation. However, ethnicity and year of participation proved not to be significant in this study. The results of this study indicate that socio-cultural variables play an integral role in the attitudes and behaviours of students. This knowledge is an important factor for informal educators to consider when designing experiential, environmental programs.

description: Long-range contributions to the three-nucleon force that have been recently worked out in chiral effective field theory at next-to-next-to-next-to-leading order are for the first time included in the triton and the doublet nucleon-deuteron scattering length calculations. The strengths of the two short-range terms available at this order in the chiral expansion are determined from the triton binding energy and the neutron-deuteron doublet scattering length. The structure of the resulting three-nucleon force is explored and effects for the two-nucleon correlation function in the triton are investigated. Expectation values of the individual contributions to the three-nucleon force in the triton are found to be in the range from a few 100 keV to about 1 MeV. Our study demonstrates that the very complicated operator structure of the novel chiral three-nucleon forces can be successively implemented in three-nucleon Faddeev calculations.

TeV sky versus AUGER one: are UHECR also radioactive, heavy galactic nuclei?

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: UHECR (Ultra High Cosmic Rays) made by He-like lightest nuclei might solve the AUGER extragalactic clustering along Cen A: He UHECR cannot arrive from Virgo because the light nuclei fragility and opacity above few Mpc; UHECR signals are clustering along Cen-A spreading as observed by horizontal galactic arms magnetic fields, along random vertical angles [18]. Cen A events by He-like spread along a width angle as large as the observed clustered one. UHECR He, being fragile should partially fragment in secondaries at tens EeV multiplet (D,He3,p) almost as it occurs in the very recent UHECR multiplet at 20 EeV along Cen A UHECR clustering [23]. Their narrow crowding within a tiny (Cen A centric disk) observation area (below 10^{-2} of the whole AUGER sky) aligned with Cen A may occur by a very low probability, below 3 \dot 10^{-5}, see Fig. 1, 2,3, [23]. Remaining UHECR spread group show correlations with other gamma (MeV-Al^26 radioactive) maps, mainly due to galactic SNR sources as Vela pulsar, the brightest, nearest GeV source [20]. Other nearest galactic gamma sources (as partially Crab and Galactic Center core) show links with UHECR via TeV correlated maps, see Fig.7. We speculate here that UHECR are also heavy radioactive galactic nuclei as Ni^56, Ni^57 and Co^57,Co^60 widely bent (tens degree up to \geq 100°) by galactic fields. UHECR radioactivity (in beta,gamma channels) decay in flight at hundreds keV is boosted (by huge Lorentz factor \simeq 10^9 - 10^8) leading to TeVs gamma correlated sky anisotropy, see Fig.7. Tau neutrinos secondaries and their tau airshowers at horizons may rise (from hundreds TeVs-PeVs) in future ICECUBE,ANTARES [28], double bang events [29], or in ARGO and ASHRA [1] horizons or in AUGER or TA airshowers at PeVs-EeV energies, showing the expected Neutrino astronomy link to UHECR decay in flight.

description: Spatiotemporal complexity is induced in a two dimensional nonlinear disordered lattice through the modulational instability of an initially weakly perturbed excitation. In the course of evolution we observe the formation of transient as well as persistent localized structures, some of which have extreme magnitude. We analyze the statistics of occurrence of these extreme collective events and find that the appearance of transient extreme events is more likely in the weakly nonlinear regime. We observe a transition in the extreme events recurrence time probability from exponential, in the nonlinearity dominated regime, to power law for the disordered one.

description: Introduction/ Background
In recent years, telepathology has played an increasingly important role in pathology consultation/second opinion. SinceChinaimplemented a national/central telepathology network for cancer diagnosis in 2011, many provinces have also planned and implemented their own provincial or local telepathology networks.
Aims
We here reported the provincial telepathology network and their operation from 2012 to 2015. We also reported their connection to national/central network.
Methods
All available provincial and local telepathology networks inChinawere surveyed. Only those provincial or local telepathology networks meet following criteria were included: (1) Network uses whole slide images and internet based platform technology; (2) Network sponsored or owned by provincial or local pathology quality control center; (3) Network currently functioning.
Results
From 2011 to Dec 2015, 6 provincial telepathology networks have been implemented. Xinjiang provincial network was set up in 2011 and connected to 40 local hospitals; Shandong provincial network (www.pathol- ogy.telemedicine.net.cn) was established in 2012 and connected to 50 local hospitals; Hainan provincial network (59.50.108.88) was set up in 2013 and connected to all 50 local hospitals in the province; Guangxi provincial network (www.gx.chinapathology.cn) was set up in 2013 and connected to 28 hospitals; Shenzhen city network (www.szcenter.cn) was set up in 2013 and connected to 15 local hospitals; Fujian provincial network (www.fj.mpathology.cn) was connected to 107 local hospitals. By 2015, 5 out of the 6 provincial networks have connected to national/central network. From 2012 to 2015, both national/central network and provincial networks provided pathology consultation for a total of 78,264 patients. Our survey indicated that in recent years multiple provincial telepathology networks have been set up in China. Through both national/central and provincial networks, telepathology consultation has played an important role in reducing diagnostic errors inChina.

Towards an open pipeline for the detection of Critical Infrastructure from satellite imagery – A case study on electrical substations in The Netherlands
Creators: name: J J-F G DE PLAEN
Publisher: name: Zenodo
Year: 2023

description: Abstract. Critical infrastructure (CI) are at risk of failure due to the increased frequency and magnitude of climate extremes related to climate change. It is thus essential to include them in a risk management framework to identify risk hotspots, develop risk management policies and support adaptation strategies to enhance their resilience. However, the lack of information on the exposure of CI prevents their incorporation in large-scale risk assessment studies. This study sets out to improve the representation of CI for risk assessment studies by building a neural network model to detect CI assets from optical remote sensing imagery. We present a pipeline that extracts CI from OpenStreetMaps, processes the imagery and assets’ masks, and trains a Mask R-CNN model that allows for instance segmentation of CI at the asset level. This study provides an overview of the pipeline and tests it with the detection of electrical substations assets in the Netherlands. Several experiments are presented for different under-sampling percentages of the majority class (25%, 50% and 100%) and hyperparameters settings (batch size and learning rate). The best metrics achieved are an Average Precision at an Intersection over Union of 50% of 30.93 and a tile F-score of 89.88%. This allows us to confirm the feasibility of the method and invite disaster risk researchers to use this pipeline for other infrastructure types. We conclude by exploring the different avenues to improve the pipeline by addressing the class imbalance, Transfer Learning and Explainable AI.

description: We apply Bogoliubov compensation principle to the gauge electro-weak interaction to demonstrate a spontaneous generation of anomalous three-boson gauge invariant effective interaction. The non-trivial solution of compensation equations uniquely defines the form-factor of the anomalous interaction and parameters of the theory including value of gauge electro-weak coupling $g(M_W^2)$ in satisfactory agreement with its experimental value. A possibility of spontaneous generation of effective four-fermion interaction of heavy quarks is also demonstrated. This interaction defines an equation for a scalar bound state of heavy quarks which serve as a substitute for the elementary scalar Higgs doublet. As a result we calculate the $t$-quark mass $m_t\,=\,177\,GeV$ in satisfactory agreement with the experimental value. The results strongly support idea of $\bar t\,t$ condensate as a source of the electro-weak symmetry breaking.

description: We present a study of magnetic properties of single-crystal Co3O4 nanowires with diameter about 7 nm. The nanowires expose (111) planes composed of plenty of Co3+ cations and exhibit two Néel temperatures at 56 K (TN of wire cores) and 73 K (TN of wire shells), which are far above TN = 40 K of bulk Co3O4. This novel bahavior is attributed to symmetry breaking of surface Co3+ cations and magnetic proximity effect. The nanowire shells show macroscopic residual magnetic moments. Cooling in a magnetic field, a fraction of the residual moments are tightly pinned to the antiferromagnetic lattice, which results in an obvious horizontal and vertical shift of hysteresis loop. Our experiment demonstrates that the exchange bias field HE and the pinned magnetic moments Mpin follow a simple expression HE = aMpin with a a constant.
Whose Open Science? And Why Infrastructure Matters

description: This is the presentation slide deck for the keynote at OpenCon Cascadia, Feb. 1-2 2019 In this talk, I argue that scholarly communication and scientific knowledge production should be seen as a complex system of power that favours privileged institutions and individuals, and marginalize and even oppress those who do not conform to the norms and “standards” established by the powerful. The result is a deeply entrenched epistemological hierarchy. Openness alone cannot “transform” this complex as this interlocking system of institutions and technology are deeply rooted in past political and ideological structures. They have become invisible infrastructure and seldom questioned. To begin to disrupt this system, we need to go beyond challenging the visible barriers of the system, notably paywall and licensing issues, to question the hidden and invisible power that sustains and replicate power and privilege. To this end, we need to rethink what constitutes infrastructure, who has the power to build and govern them, what informs its design, who are subjected to its “governance”, and the consequences for the powerless. In particular, I wish to focus on infrastructure as forms of invisible power. I will provide examples to demonstrate that simply imposing “open” on closed infrastructures serve to replicate existing power inequality and epistemic injustice. Openness, when decontextualized from its historical and political roots, could become as exploitative and oppressive as the legacy system it seeks to displace.

description: Introduction/ Background
Digital Pathology represents a technological innovation that introduces changes in the traditional work of pathologists. In this regard, an important issue that has not been enough emphasized is the image handling from an ergonomic point of view to avoid work-related musculoskeletal disorders (MSD).
Aims
The aim of this study was to investigate a proper input device for digital pathology.
Methods
Research was conducted in two phases: 1. Comparative study to find an optimal external controller. Eight medical students analyzed 11 input devices: keyboard (HP), conventional mouse (HP), vertical mouse (CLS), touchpad (Logitech), 3 trackballs (Logitech, Kensington Expert and Ulove), Rollermouse (Contour), Ergopointer (Märzhäuser Sensotech), gamepad (Logitech) and a touchless device (Leap-Motion), using them with the Image Viewer software (Ventana). The web-based Fitts´ law test (UC Berkeley) was used to objectify the accuracy of each device, randomly. 12 items were included in the questionnaire: comfort, technical aspects (cursor movement and objective achievement), prospects, overall satisfaction, prior experience, and others. 2. Evaluation by two experienced pathologists (MPR and ANO, 55 and 50 year-old, respectively) the best rated input device and comparison with a voice recognition system (Invox Medical Dictation) using a headset microphone (Plantronics), rating perceived workload using NASA Task Load Index with 28 whole slide images. Digital Image Hub (Leica) with a 4 MegaPixel display (Barco) was used. Data were processed with SPSS 21.0.
Results
Correlation between technical aspects of the evaluated devices and accuracy (Fitts´ law test), and comfort with overall satisfaction existed (p<0.05). The assessment concluded that vertical mouse was the best rated input device. However, it has a slightly higher perceived workload in comparison with the voice recognition system, which was the proper controller for digital pathology in this study.

Conclusion: We describe a methodology that can study and compare input devices for future workstations in digital pathology. Pathologists should be involved in this process trying to find ergonomic devices that prevent MSD. Voice recognition can function as a good handsfree device for digital pathology and could be considered in physical disability situations. Further studies using electromyography, accelerometry and 3D reconstruction analysis could provide additional ergonomic information.

description: How do humans coordinate their movements in order to avoid pain? This paper investigates a motor task in the presence of concurrent potential pain sources: the arm must be withdrawn to avoid a slap on the hand while avoiding an elbow obstacle with an electrical noxious stimulation. The results show that our subjects learned to control the hand retraction movement in order to avoid the potential pain. Subject-specific motor strategies were used to modify the joint movement coordination to avoid hitting the obstacle with the elbow at the cost of increasing the risk of hand slap. Furthermore, they used a conservative strategy as if assuming an obstacle in 100% of the trials.

description: This study investigated the in vitro effect of propolis ethanolic extract (PEE) on planktonic growth and biofilm forming abilities of five commercial probiotics (Enterol, Protexin, Normaflore, BioGaia and Linex). Broth microdilution method was used to investigate the susceptibility of the microbes of five commercial probiotics to PEE. Crystal violet assay was used for the quantitative assessment of biofilm formation and mature biofilm eradication tests. Effect of PEE on autoaggregation ability and swarming motility of Normaflore microbes was determined. Planktonic forms of probiotics showed varied susceptibilities with minimal inhibitory concentration values in the range of 100-800 µg/mL of PEE. However, low PEE concentrations significantly enhanced the planktonic growth of Linex and BioGaia microbes. Biofilm studies revealed that Enterol and Protexin were non-biofilm formers, while BioGaia, Linex and Normaflore showed weak biofilms, which were inhibited by 12.5, 25, and 800 µg/mL of PEE, respectively. PEE revealed double-face effect on the biofilms of Normaflore and Linex, which were enhanced at low concentrations of PEE and inhibited at higher concentrations. Interestingly, Normaflore biofilms were shifted from weak to strong biofilms at low PEE concentrations (12.5, 25, and 50 µg/mL). In conclusion, PEE has strain dependent controversial effects on the planktonic growth and biofilm forming ability of the tested probiotics, although high concentrations have inhibitory effect on all of them, low concentrations may have strain dependent prebiotic effect.

description: Introduction/ Background
The measurement of cell proliferation via Ki67 immunohistochemistry is an important part of tumor diagnostics leading to treatment decisions. The assessment according to the current guidelines is very time consuming which likely leads to counting only few cells or making the analysis completely estimated in many cases. Here, automated image analysis promises a standardized, time-saving and reproducible assessment.
Aims
We prior developed a computerized method that allows for an automated scoring of Ki67. This approach was validated with a study cohort of more than 1000 patients and showed a very high significance in both overall and disease free survival. The aim of this study was to test the capability of this method for the application in the daily routine diagnostics with the concomitant time pressure and huge variability in the patient material and staining results.
Methods
The developed computer algorithm and software was applied in daily routine breast cancer diagnostics under real conditions over more than one year. More than 100 cases have been analyzed.
Results
The retrospective analysis showed that the method was capable of accurately processing most of the images. Problems occurred when the counter staining was too weak which made it even difficult to conventionally assess those images. A user interaction was required in some cases to exclude falsely counted non-tumor cells.

description: Introduction/ Background
Gene expression studies have identified molecular subtypes of breast cancer with implications to chemotherapy recommendations. For distinction of these types a combination of hormone receptors and proliferative activity of tumor cells, estimated by Ki67 labeling index from immunohistochemistry (IHC) is used. Clinical studies are frequently based on IHC performed on tissue microarrays (TMA) with variable tissue sampling. This raises the need for evidence-based sampling criteria for individual studies. We present a novel tissue sampling simulation model and demonstrate its application on Ki67 assessment in breast cancer tissue taking into account its intra-tumoral heterogeneity.
Aims
The aim is, using a novel method for easy virtual TMA simulation, to determine the optimal tissue sampling requirements in the context of variable intra-tissue heterogeneity level of Ki67 immunohistochemistry in breast cancer.
Methods
Whole slide images (WSI) of 297 primary breast tumors immunohistochemically stained for Ki67 were subjected to digital image analysis (DIA). Percentage of invasive tumor cells stained for Ki67 were computed for hexagonal tiles superimposed on the WSI. From this, intra-tumoral Ki67 heterogeneity indicators (Haralick’s entropy values) were extracted and used to dichotomize the tumors into homogeneous and  heterogeneous populations. Simulations with random selection of hexagons, equivalent to 0.75 mm circular diameter, were performed. The tissue sampling requirements were investigated in relation to tumor heterogeneity using linear regression and extended error analysis.
Results
The sampling requirements were dependent on the heterogeneity of the biomarker expression. To achieve a coefficient error of 10%, 5-6 cores were needed for homogeneous cases, while 11-12 cores for heterogeneous cases. In mixed tumor population, 8 TMA cores were required. Similarly, to achieve the same accuracy, approximately 4,000 nuclei must be counted when the intra-tumor heterogeneity is mixed/unknown. Tumors at the lower scale of proliferative activity would require larger sampling (10-12 TMA cores, or 5,000 nuclei) to achieve the same error measurement results as for highly proliferative tumors. Our data show that optimal tissue sampling for IHC biomarker evaluation is dependent on the heterogeneity of the tissue under study and needs to be determined on a per-use basis. We propose a method that can be applied to determine the TMA sampling strategy for specific biomarkers, tissues and study targets. In addition, our findings highlight the importance of high-capacity computer-based IHC measurement techniques to improve accuracy of the testing.

description: This article determines the asymptotics of the expected Riesz s-energy of the zero set of a Gaussian random systems of polynomials of degree N as the degree N tends to infinity in all dimensions and codimensions. The asymptotics are proved more generally for sections of any positive line bundle over any compact Kaehler manifold. In comparison with the results on energies of zero sets in one complex dimension due to Qi Zhong (arXiv:0705.2000) (see also [arXiv:0705.2000]), the zero sets have higher energies than randomly chosen points in dimensions > 2 due to clumping of zeros.

description: Introduction/ Background
Manual assessment of HER2 protein expression in gastric and gastroesophageal junction (GGEJ) adenocarcinomas is prone to inter-observer variability and hampered by tumor heterogeneity and different scoring criteria. Cases are frequently referred to FISH.
Aims
This study aimed to evaluate the accuracy of digital image analysis (DIA) for the assessment of HER2 protein expression.
Methods
110 GGEJ adenocarcinomas were included in TMAs with 3 tissue cores per case. Two immunoassays, PATHWAY® and HercepTest™, and FISH were performed. The HER2 CONNECT™ DIA software as designed for breast carcinoma was applied. Connectivity, calculated by the software, was converted to standard IHC scores applying predetermined cut-off values for breast carcinoma as well as novel cut-off values.
Results
Applying HER2 CONNECT™ with established connectivity cut-off values designed for breast carcinoma resulted in 72.7% sensitivity and 100% specificity for the identification of HER2 positive cases. By application of new cut-off values, the sensitivity was increased to 100%, while the specificity remained 100%. With the new cut-off values, a 36-50% reduction of IHC equivocal cases requiring additional FISH analysis was observed. Conclusion: HER2 CONNECT™ with adjusted cut-off values seems to be an effective tool for the assessment of HER2 protein expression in GGEJ adenocarcinomas, allowing for a decreased need for FISH analyses.

description: Bohr's principle of complementarity lies at the central place of quantum mechanics, according to which the light is chosen to behave as a wave or particles, depending on some exclusive detecting devices. Later, intermediate cases are found, but the total information of the wave-like and particle-like behaviors are limited by some inequalities. One of them is Englert-Greenberger (EG) duality relation. This relation has been demonstrated by many experiments with the classical detecting devices. Here by introducing a quantum detecting device into the experiment, we find the limit of the duality relation is exceeded due to the interference between the photon's wave and particle properties. However, our further results show that this experiment still obey a generalized EG duality relation. The introducing of the quantum device causes the new phenomenon, provides an generalization of the complementarity principle, and opens new insights into our understanding of quantum mechanics.

Citizenship under construction : student ideologies and social studies education

description: Social studies education has always had an emphasis on citizenship, a role that grows increasingly important as our society falls under the hegemonic control of neoliberal ideology. As elite interests become embedded and misrepresented in the collective consciousness as collective interests, it becomes imperative to explore the nature of ideological development. Accountability schemes that employ standards-based reforms and high-stakes testing further entrench hegemonic social control by narrowing the curriculum, discouraging critical thinking, and eroding teachers’ autonomy. These effects are of particular concern to social studies educators. This study employed purposive sampling to identify students who were opinionated and well-versed in political and social issues. Students were interviewed from two Alberta high schools to examine their personal ideologies, their construction of a sense of democratic citizenship, and the influences that contributed to these ideological beliefs. Special attention was paid to the role of social studies curriculum and pedagogy in fostering democratic ideals. The students identified parents and school, particularly social studies, as the greatest influences on their values and opinions. They showed collectivist tendencies and placed great value on equality, but they also showed evidence of having internalized the capitalist and individualistic rhetoric of neoliberalism. These students conceived of democracy in narrow terms and identified with passive modes of citizenship and political participation. These findings also point to the hegemonic effects of neoliberal ideology. However, the contradictions and timidity of many students’ opinions indicate that their ideologies remain very much under construction. We can begin the work of creating a more democratic and equitable society by teaching social studies in ways that foster the development of critically minded, active citizens who recognize the need for social transformation.

description: The recently developed method combining the configuration interaction and the coupled-cluster method was demonstrated to provide accurate treatment of correlation corrections in divalent atomic systems [M.S.Safronova, M.G.Kozlov, and C.W.Clark, Phys. Rev. Lett. 107, 143006 (2011)]. We have extended this approach to the calculation of quadrupole polarizabilities alpha_2 and applied it to evaluate alpha_2 for the ground state of Mg and Mg-like Si^{2+}. Performing the calculations in three different approximations of increasing accuracy allowed us to place the upper bounds on the uncertainty of the final results. The recommended values alpha_2(3s^2 1S0)= 35.86(13) a.u. for Si^{2+} and alpha_2(3s^2 1S0)= 814(3) a.u. for Mg are estimated to be accurate to 0.37%. Differences in quadrupole polarizability contributions in neutral Mg and Si^{2+} ion are discussed.
