description: Extraction of the Baryon Acoustic Oscillations (BAO) to percent level accuracy is challenging and demands an understanding of many potential systematic to an accuracy well below 1 per cent, in order ensure that they do not combine significantly when compared to statistical error of the BAO measurement. Sloan Digital Sky Survey (SDSS)-III Baryon Oscillation Spectroscopic Survey (BOSS) SDSS Data Release Eleven (DR11) reaches a distance measurement with $\sim 1\%$ statistical error and this prompts an extensive search for all possible sub-percent level systematic errors which could be safely ignored previously. In this paper, we analyze the potential systematics in BAO fitting methodology using mocks and data from BOSS DR10 and DR11. We demonstrate the robustness of the fiducial multipole fitting methodology to be at $0.1\%-0.2\%$ level with a wide range of tests in mock galaxy catalogs pre- and post-reconstruction. We also find the DR10 and DR11 data from BOSS to be robust against changes in methodology at similar level. This systematic error budget is incorporated into the the error budget of Baryon Oscillation Spectroscopic Survey (BOSS) DR10 and DR11 BAO measurements. Of the wide range of changes we have investigated, we find that when fitting pre-reconstructed data or mocks, the following changes have the largest effect on the best fit values of distance measurements both parallel and perpendicular to the line of sight: (a) Changes in non-linear correlation function template; (b) Changes in fitting range of the correlation function; (c) Changes to the non-linear damping model parameters. The priors applied do not matter in the estimates of the fitted errors as long as we restrict ourselves to physically meaningful fitting regions.[abridged]

description: Variability is one of the most defining characteristic of Active Galactic Nuclei (AGN), and it is observed in every waveband in which they have been studied. For this reason variability studies are fundamental to understand the extreme physical conditions of accretion disks near supermassive black holes. Several efforts have been done to analyze the variability in the optical range, however, in order to relate the variability and physical properties of AGN, we need well sampled light curves. On the other hand, very little is known about the variability in the infrared range. This waveband gives us information about the dust surrounding the accretion disk at low redshift, and about the accretion disk at high redshift.

In this talk, we will present the current status of our QUEST-La Silla AGN variability survey. This is an effort to obtain well sampled optical light curves of AGN in extragalactic fields with unique multiwavelength observations, using the QUEST camera on the ESO-Schmidt telescope.The survey uses a broadband filter, the Q-band, similar to the union of the g and the r filters. In particular, we will present the status of the analysis of the COSMOS, ELAIS-S1 and Stripe82 fields. Besides, we will present our statistical study of the near infrared (NIR) variability of AGN in the COSMOS field, using UltraVISTA data. This dataset give us a huge sample of light curves, making possible to have a global description of the nature of AGNs for different ranges of redshift, and for different levels of obscuration. By using both surveys, we expect to have a better understanding of the difference between type 1 and type 2 AGN.
Two-particle asynchronous quantum correlation: wavefunction collapse acting as a beamsplitter

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)

description: A two-body quantum correlation is calculated for a particle reflecting from a moving mirror. Correlated interference results when the incident and reflected particle substates and their associated mirror substates overlap. Using the Copenhagen interpretation of measurement, an asynchronous joint probability density (PDF), which is a function both of the different positions and different times at which the particle and mirror are measured, is derived assuming that no interaction occurs between each measurement. Measurement of the particle first, in the correlated interference region, results in a splitting of the mirror substate into ones which have and have not reflected the particle. An analog of the interference from the Doppler effect for only measurements of the particle (a marginal PDF), in this two-body system, is shown to be a consequence of the asynchronous measurement. The simplification obtained for a microscopic particle reflecting from a mesoscopic or macroscopic mirror is used to illustrate asynchronous correlation interferometry. In this case, the small displacement between these mirror states can yield negligible environmental decoherence times. In addition, interference of these mirror states does not vanish in the limit of large mirror mass due to the small momentum exchange in reflecting a microscopic particle.

description: Project PROGRESS (Promoting Renewable energy research On the Grid to create Responsible STEM workforce in Solar Sustainability) is a unique first-time multidisciplinary program that provides an ideal opportunity for all participants, including students, faculty, and the workforce in the state to learn through experience and research. Students in this course are charged to develop innovative ideas to grow and sustain renewable energy research in the commonwealth of Virginia through a hands-on, experiential, and project-based approach. This project has helped to promote the much needed awareness of the importance of community-based solar energy by engaging various stake-holders in studying its impact and assessing its benefits, while supporting and encouraging solar energy growth in Virginia. The Dominion Foundation, the philanthropic arm of the Dominion Power (Virginia), funded this experimental STEM course.

The two principle outcomes of this project include: (a) Engaging students in a new hands-on course that will be developed called â€œSTEM for Solarâ€ and; (b) Engaging the students in self-directed research on a variety of projects involving Solar including Virginia energy issues, critical energy infrastructure, smart-grid technology, and sustainability.

Project PROGRESS includes a multi-disciplinary team of faculty and experts from various disciplines and industry. Student research projects include developing new designs of technologies to make solar energy economical to storing solar energy and beyond. This course stands a model of collaboration between a local philanthropic organization and GMU. Many aspects of STEM and public policy, applicable to the entire student body of COS, and Engineering are reviewed.

description: Situational Crime Prevention (SCP) intervenes in the causes which offenders encounter, or seek out, in the immediate circumstances of the criminal event.Situational Crime Prevention activities are extremely varied. However, they can be classified into just 25 techniques, organised in terms of which factors (risk, effort, reward, provocation, excuses) they primarily tackle. This schema is mainly the work of Professor Ron Clarke operating through the Center for Problem-Oriented Policing.The 25 generic SCP techniques provide inventive principles and ideas for designers and anyone else who wants to kick-start thinking about how to design out crime. The 10 techniques outlined in this document, reinterpreted from Ron Clarke’s original categories, aim to offer open-source information about situational crime prevention from a design point of view, that is relevant to bag theft from interior environments and public spaces.

description: Creativity and innovation is at the core of the PhD programs, but it is much less present in undergraduate or master programs creating a difficult gap for many students. Moreover, the dynamics of the evolution of the current world is making creativity and innovation a requirement for many jobs. However, large class sizes, density of the material presented, domain complexity and instructor research experience are some of the limiting factors that make difficult to include creativity and innovation training in the undergraduate curriculum. In this lightning talk session, educators with practical experience in preparing undergraduate students for creativity, innovation and research, will present and debate strategies to overcome these challenges in classes of various types (e.g. online vs. in class), levels (introductory vs. specialized electives) and using a diverse spectrum of methods, (including active learning, experiential learning, team-based learning, flipped classroom, project-based learning, competition-based learning, capstone courses, and extra-curriculum activities). The session will continue with a panel discussion about the applicability of such methods in various settings, how to start including such elements in classically taught curriculum, and will answer questions from the audience. Specific case studies from the audience are encouraged and will be discussed. At the end of this session the participants will have a better understanding of available strategies and lessons learned of how to make creativity and innovation integral part of the curriculum.

description: We show that all GGS-groups with non-constant defining vector satisfy the congruence subgroup property. This provides, for every odd prime $p$, many examples of finitely generated, residually finite, non-torsion groups whose profinite completion is a pro-$p$ group, and among them we find torsion-free groups. This answers a question of Barnea. On the other hand, we prove that the GGS-group with constant defining vector has an infinite congruence kernel and is not a branch group.

Note on the physical basis of spatially resolved thermodynamic functions

description: The spatial resolution of extensive thermodynamic functions is discussed. A physical definition of the spatial resolution based on a spatial analogy of partial molar quantities is advocated, which is shown to be consistent with how hydration energies are typically spatially resolved in the molecular simulation literature. It is then shown that, provided the solvent is not at a phase transition, the spatially resolved entropy function calculated by first-order grid inhomogeneous solvation theory (Nguyen et al. J. Chem. Phys., 137, 044101 [2012]) satisfies the definition rigorously, whereas that calculated by grid cell theory (Gerogiokas et al., J. Chem. Theory Comput., 10, 35 [2014]) most likely does not. Moreover, for an ideal gas in an external field, the former theory is shown consistent in the limit of weak field or high temperature whereas the latter is not. Finally, consistent with the proposed definition and with the case of an ideal gas in an external field, we derive an approximate expression for the solvent contribution to the free energy of solvation in the limit of infinite dilution from the spatial variation of the density around the solute.

description: This thesis examines bioarchaeological patterns of periodontal disease in the 16th and 17th century Peru during a period of extreme political and socioeconomic instability involving Spanish subjugation of Andean peoples. A growing number of paleopathological studies have begun characterizing the biocultural effects of conquest in the Colonial Andes. Unfortunately, periodontal disease has remained virtually unstudied. Here, this thesis provides the first characterization of periodontal disease severity in Colonial Peru to assess this marker of diet, oral health, and systemic inflammation. The central hypothesis of this thesis predicts that periodontal disease prevalence and severity was greater in the Colonial Muchik town of Mórrope (a setting of heightened economic and biological stress) compared to their Muchik neighbors to the south in Eten (an economically stable community). Established protocols measuring CEJ-alveolar margin distances were used as a measure of periodontitis prevalence/absence and alveolar margin morphology/porosity/recession to assess severity. Sixty-four adults from Mórrope and 115 adults from Eten were examined. Data were analyzed using odds ratio (ÔR) analysis. A higher crude prevalence of periodontitis is observed in Eten (59% vs 36% in Mórrope, which was statistically significant (ÔR=0.38; p=0.01). A statistically significant difference of severity was not observed (ÔR=0.61; p=0.01). Severe expressions of periodontitis were observed in both samples (55% Mórrope and 44% Eten). These unexpected findings were interpreted in the contexts of their archaeological settings, inflammatory disease biology, patterns of other pathological conditions, and isotopic variation to suggest (1) periodontal disease was widespread and severe in these two communities, and; (2) that the extremely high prevalence of antemortem tooth loss and alveolar remodeling in Mórrope obscures documentation of potentially extreme periodontal disease in that community. This prevents straightforward comparisons between these communities and highlights new questions and opportunities in studying periodontitis in historic Peru. This findings are also considered in terms of structural violence, colonial subjugation, and systemic inflammation as embodied in expressions of periodontal disease.

description: W. G. Sebald and Patrick Modiano are two contemporary authors who share similar themes and literary practices. They are both fastidiously or even obsessively historical in their narrative development. And they seem preoccupied with the sins of World War II. Critics have divided feelings about their accomplishments. Skeptics say their trauma narratives induce despair, are complicated for complication’s sake, and overstate trauma’s imperviousness to healing. Advocates say their fictions bring historical injustices that have yet to be fully reckoned with to the present with emotional immediacy. This essay argues that Sebald’s Austerlitz (2001) and Modiano’s Dora Bruder (1997) do important political work in their fastidious historical narratives. In recreating the suffering of the past, these authors pull their readers into participating in acts of historical reparation, which are critical to social progress.

description: We consider the open STIRAP problem by formulating it in terms of generalized Bloch equations. Expressed in this form the resulting Liouvillian matrix is analyzed in detail. As it turns out, most of the findings of open STIRAP models can be understood from the spectrum and eigenstates of the Liouvillian matrix. As a non-hermitian matrix we particularly discuss the mathematical structure of it by identifying among others the physical meaning of its eigenvectors and the system's exceptional points. We also discuss the importance of the Liouvillian gap which normally implies that any state becomes mixed. However, in certain situations, for example the STIRAP model under influence of spontaneous emission, a sort of pump term appears in the equations of motion, and its effect is to counteract the gap induced decay such that coherence may prevail. As the STIRAP driving is not perfectly adiabatic, we additionally find that for spontaneous emission the presence of a non-zero Liouvillian gap actually enhances the success rate of the process. This is thus an example of a environment assisted physical operation.

description: The project known as PhET, originally stood for Physics Education Technology, but was quickly expanded into the other natural sciences.Â  It is a project which, with a grant from the NSF and other sponsors, now provides free inquiry- based simulations in the natural sciences and mathematics.Â  The project was founded by Nobel Prize winner Carl Wieman. The simulations are highly interactive, easy to use, and based on the latest educational research. The GMU Honors College teaches several science courses geared to high achieving liberal arts students.Â  The courses cover a wide range of topics that include astrobiology, energy/environmental issues, and scientific thought and processes. Despite their high ability and motivation, these students often report a reluctance to engage in scientific inquiry. Â PhET simulations were used as laboratory experiments to teach basic concepts in physics and chemistry. Students display high engagement and interest utilizing PhET simulations. Students also were able to demonstrate creativity in problem solving, and a reduced fear of making mistakes. Â The PhET computer simulations allowed students to quickly identify cause and effect relationships between simulation inputs and outputs.

Â Approaching instruction from the seemingly disparate disciplines of rhetoric, game writing, and nursing, the presenters will focus on some specific strategies borrowed from Engaging Imagination: Helping Students Become Creative and Reflective Thinkers (James & Brookfield, 2014). The presenters will share the results of these â€œexperimentsâ€ in the classroom and reflect on how framing/re-framing some aspects of their pedagogy in terms of imagination towards reflection has affected their teaching.

Takeaway: Attendees will participate in versions of these classroom â€œexperimentsâ€ and be allowed to judge the effectiveness/utility of such strategies informed with hands-on experience.Â  Presented by faculty from disparate disciplines, attendees will see firsthand the common ties for any teaching occasion where deep reflection and engagement are a goal, leaving with ideas for new or augmented activities that benefit students and provide new challenges for instructors.

description: Reflection plays an important role in the development of new courses and curriculum. Professional skills development is the focus of two newly developed and required courses, one of which uses reflection as a primary pedagogical practice. These foundational courses are scaffolded by design. The scope of this presentation will be on the first of these two courses, designed for students entering the university environment and serving as early exposure to the field. Â

Presenters will share the role that reflection played, and continues to play, in the development of these courses. One assignment, a product of this reflection, will serve as a focus of this presentation. It was developed to challenge students to consider past experiences and how they might apply to the development of their professional skills, both now and in the future. Peer review and feedback sessions serve as another instructional tool to facilitate this critical thinking process.

The first focus of this presentation will be on continual instructor reflection on course and curriculum design as a method for enhancing the pedagogical approach, instruction, and assignments, and it will continue to play a role in the assessment of course outcomes. The second focus will be on the role that critical reflection plays as a pedagogical practice in course design and classroom instruction. Session attendees will be asked to reflect on their pedagogical practice and the role reflection has played in their approach to classroom learning.

description: Following the model of the University of Colorado at Boulder Learning Assistant (LA) program, the College of Science (COS) at Mason began its own LA program in 2012. The program is a key segment of the STEM Accelerator program, and is a keystone for retaining students in COS and enabling them to graduate in a timely manner. COS STEM Accelerator has now supported over 300 undergraduate LAâ€™s since it's inception through both internal and external funding. The LA program is very successful in increasing grades, engaging students in large lecture classes, enabling faculty to better utilize the ALT classroom, increasing retention in sciences and also increasing confidence and GPAâ€™s for the undergraduate LAâ€™s.Â  The cornerstones of the LA program are student mentoring by the faculty sponsor, a required seminar in pedagogical techniques, and face-to-face time with students in the classroom.

Â

This interactive presentation will include information about the program in COS. Faculty and students will demonstrate examples of how LAâ€™s are integrated into different learning environments and across disciplines.Â  Examples will include LAâ€™s in the ALT classroom, in large and small lectures, in lab, in orals, and on-line.Â  Disciplines include Biology, Chemistry, Forensic Science, Geography, Geology, Math and Physics.Â  Attendees will understand the program and itâ€™s key concepts, discuss how an LA could work in their classroom and discipline, and understand how COS is working to enable your students to conquer their MATH and Mason Core Science classes.

Using this code we calculated the quasiparticle phonon frequencies and linewidths of crystalline silicon at different temperatures using both of first-principles and the Tersoff empirical potential approaches. In this work we show the dependence of these properties on the temperature using both approaches and compare them with reported experimental data obtained by Raman spectroscopy [M. Balkanski, R. Wallis, E. Haro, 1983 and R. Tsu, J. G. Hernandez, 1982].

Pro-$\mathcal{C}$ congruence properties for groups of rooted tree automorphisms

description: We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees. Instead of only comparing the profinite completion to that given by level stabilizers, we also compare pro-$\mathcal{C}$ completions of the group, where $\mathcal{C}$ is a pseudo-variety of finite groups. A group acting on a rooted, locally finite tree has the $\mathcal{C}$-congruence subgroup property ($\mathcal{C}$-CSP) if its pro-$\mathcal{C}$ completion coincides with the completion with respect to level stabilizers. We give a sufficient condition for a weakly regular branch group to have the $\mathcal{C}$-CSP. In the case where $\mathcal{C}$ is also closed under extensions (for instance the class of all finite $p$-groups for some prime $p$), our sufficient condition is also necessary. We apply the criterion to show that the Basilica group and the GGS-groups with constant defining vector (odd prime relatives of the Basilica group) have the $p$-CSP.

Shellability of face posets of electrical networks and the CW poset property

description: We prove a conjecture of Thomas Lam that the face posets of stratified spaces of planar resistor networks are shellable. These posets are called uncrossing partial orders. This shellability result combines with Lam's previous result that these same posets are Eulerian to imply that they are CW posets, namely that they are face posets of regular CW complexes. Certain subsets of uncrossing partial orders are shown to be isomorphic to type A Bruhat order intervals; our shelling is shown to coincide on these intervals with a Bruhat order shelling which was constructed by Matthew Dyer using a reflection order.
 Our shelling for uncrossing posets also yields an explicit shelling for each interval in the face posets of the edge product spaces of phylogenetic trees, namely in the Tuffley posets, by virtue of each interval in a Tuffley poset being isomorphic to an interval in an uncrossing poset. This yields a more explicit proof of the result of Gill, Linusson, Moulton and Steel that the CW decomposition of Moulton and Steel for the edge product space of phylogenetic trees is a regular CW decomposition.

description: As the independent evaluator, CIE is charged with four primary goals: 1) verification of Twaweza’s outputs; 2) identification of outcomes/effects; 3) analysis of the relation between outputs and outcomes/effects; and 4) review of the appropriateness of Twaweza’s theory of change. A secondary goal is to contribute to Twaweza’s learning and communications processes by making rigorous analyses which invite probing questions and discussions available on a regular basis to the Learning & Communications Team. This is often referred to as ‘formative evaluation’, although that concept trivializes the depth of interaction and supported questioning that Twaweza is committed to. These analyses and discussions will focus on ‘what is working well’, on ‘what needs re-positioning or re-calibrating’, and on ‘what is just not working at all.’

description: In this talk we compare single-epoch (SE) black hole mass (MBH) estimates based on low ionization (Hα, Hβ, and MgII) and high ionization (CIV) broad emission lines. We also  examine the implications of different continuum modeling approaches in line width and MBH measurements. For this purpose we use a sample of 39 unobscured AGNs at z=1.55 selected to cover a large range in MBH (2.0dex) and L/Ledd (2.5dex) and observed by X-shooter.  We find that using a local power-law continuum instead of a physically-motivated thin disk continuum leads to only slight underestimation of the FWHM of the lines and the associated MBH(FWHM). However, the line dispersion σ and associated MBH(σ) are strongly affected by the continuum placement providing less reliable mass estimates. We find that low ionization lines provides reliable virial MBH estimation. However, the CIV line is not reliable in the majority of the cases, indicating that the gas emitting this line may not be  virialized. We find that Hα, Hβ show similar line widths and that FWHM(MgII) is about 30% narrower than FWHM(Hβ) . We test and confirm several recent suggestions to improve the accuracy in CIV-based mass estimates, relying on other UV emission lines. However, we find that such improvements do not help in reducing the scatter between CIV-based and Balmer-line-based mass estimates. This work has been recently accepted for publication in MNRAS.
