description: We are developing the Cryogenic AntiCoincidence detector (CryoAC) of the ATHENA X-IFU spectrometer. It is a TES-based particle detector aimed to reduce the background of the instrument. Here, we present the result obtained with the last CryoAC single-pixel prototype. It is based on a 1 cm2 silicon absorber sensed by a single 2mm x 1mm Ir/Au TES, featuring an on-chip heater for calibration and diagnostic purposes. We have illuminated the sample with 55Fe (6 keV line) and 241Am (60 keV line) radioactive sources, thus studying the detector response and the heater calibration accuracy at low energy. Furthermore, we have operated the sample in combination with a past-generation CryoAC prototype. Here, by analyzing the coincident detections between the two detectors, we have been able to characterize the background spectrum of the laboratory environment and disentangle the primary (i.e. cosmic muons) and secondaries (mostly secondary photons and electrons) signatures in the spectral shape.

description: Rapid urbanization has caused serious adverse environmental impacts across the globe, including increased emissions of carbon dioxide from burning of fossil fuels, reduced natural vegetation, and loss in biodiversity. Urbanization also affects plant photosynthesis and growth. It is of great importance to understand the direct and indirect impact of urbanization on plants as plants are the major sink of atmospheric CO2. In the present study, chlorophyll fluorescence was used to examine the effects of urbanization on the thermal tolerance of photosynthesis of Quercus rubra L., red oak, growing along an urban to rural transect in New York State. The study assessed the yield of chlorophyll fluorescence (Fv/Fm) of red oak under rapidly increasing heat stress, and quantified the critical temperature (Tcrit) at which photosystem II (PSII) protein complex efficiency degrades. The Tcrit was greatest at Lamont–Doherty, a suburban area, followed by rural Black Rock Forest, urban Central Park, and remote Ashokan Reservoir. These patterns indicated that thermotolerance was enhanced in the suburban area, whereas it was decreased in the urban area compared to the remote and rural areas. The effect of temperature alone on maximal PSII efficiency of light capture (Fv/Fm) was less evident, suggesting that the Fv/Fm might be influenced by an interaction of multiple factors, such as temperature, light, CO2 concentration, and nutrient availability. In addition, applying a single regression analysis on combined measurement data from different months, where different environmental factors could be operating, may limit the accurate estimation of Fv/Fm. Although further experimental investigations are needed in order to understand the impact of urbanization on Fv/Fm, the present study contributes toward a better understanding of the effect of urbanization on photosynthesis.

description: We present a universal normal algebra suitable for constructing and classifying Calabi-Yau spaces in arbitrary dimensions. This algebraic approach includes natural extensions of reflexive weight vectors to higher dimensions, related to Batyrev's reflexive polyhedra, and their n-ary combinations. It also includes a `dual' construction based on the Diophantine decomposition of invariant monomials, which provides explicit recurrence formulae for the numbers of Calabi-Yau spaces in arbitrary dimensions with Weierstrass, K3, etc., fibrations. Our approach also yields simple algebraic relations between chains of Calabi-Yau spaces in different dimensions, and concrete visualizations of their singularities related to Cartan-Lie algebras. This Universal Calabi-Yau Algebra is a powerful tool for decyphering the Calabi-Yau genome in all dimensions.

description: Understanding how loops in active regions are heated is a critical step in solving the coronal heating problem. In particular, constraining the frequency at which individual strands are re-energized can shed light on what mechanism releases energy from the highly-stressed magnetic field into the coronal plasma. To address this problem, we forward model time-dependent AIA intensity maps for active region NOAA 1158 using a combination of loop hydrodynamics, potential field extrapolations derived from HMI magnetograms, and detailed atomic physics. We model the AIA intensity for a range of heating frequencies and constrain the total energy input based on both observed active region flux and the magnetic field strengths derived from the field extrapolation. We then apply the time lag method of Viall and Klimchuk (2012) to compute cross-correlations for all possible channel pairs for every pixel in our synthesized active region. For a given channel pair, the delay which maximizes the cross-correlation provides a proxy for the cooling time between the two channels in a given pixel. We apply this same technique to twelve hours of AIA observations of NOAA 1158. To make meaningful comparisons between our synthetic and observed data, we train a random forest classifier on the synthesized time lags and apply it to our observed timelags in order to classify the heating frequency in each pixel of the active region. This approach allows us to easily and efficiently incorporate every channel pair in deciding which heating model is most consistent with our observed time lags in the context of our model. We also compute emission measure distributions from our modeled and observed intensities using the method of Hannah and Kontar (2012), as any successful heating model should be able to reproduce multiple observational signatures. Furthermore, we apply this analysis to several more active regions from the catalog compiled by Warren et al. (2012). In order to efficiently analyze this large time-dependent, multi-wavelength data, we use the Dask Python library for out-of-core data processing in order to take advantage of multiple computing cores when preparing and analyzing the data. Such an approach provides a pipeline for processing a many hours of full-disk, level 1 images into a series of time lag maps in a matter of a few hours. This novel combination of distributed and parallel data processing, detailed forward modeling, and machine learning allows us to survey active region heating properties at an unprecedented scale.
String Field Theory as World-sheet UV Regulator

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Even at tree level, the first quantized string theory suffers from apparent short distance singularities associated with collision of vertex operators that prevent us from straightforward numerical computation of various quantities. Examples include string theory S-matrix for generic external momenta and computation of the spectrum of string theory under a marginal deformation of the world-sheet theory. The former requires us to define the S-matrix via analytic continuation or as limits of contour integrals in complexified moduli space, while the latter requires us to use an ultraviolet cut-off at intermediate steps. In contrast, string field theory does not suffer from such divergences. In this paper we show how string field theory can be used to generate an explicit algorithm for computing tree level amplitudes in any string theory that does not suffer from any short distance divergence from integration over the world-sheet variables. We also use string field theory to compute second order mass shift of string states under a marginal deformation without having to use any cut-off at intermediate steps. We carry out the analysis in a broad class of string field theories, thereby making it manifest that the final results are independent of the extra data that go into the formulation of string field theory. We also comment on the generalization of this analysis to higher genus amplitudes.

description: Interest in the elementary education major by underrepresented minority (URM) students at a public four-year institution (Queens College) increased from 36% of declared majors in 2012 to 51% in 2017. However, a disproportionate number of URM students drop out of the educator pipeline, leaving the average percentage of URMs who complete the elementary education major at 22%. While there has been a great deal of research on the preparation of preservice teachers, the bulk of the scholarly literature is focused on the final student teaching practicum and preservice teachers’ experiences at the end of their academic programs. Little research has been done on beginning teacher education students and how their educational experiences, both past and present, influence the way they see themselves as learners and future teachers.
      Guided by a sociocultural lens, this qualitative study examines teacher education students’ educational experiences and how those experiences influence and shape their paths into the teaching profession. The study was conducted using an interpretive inquiry approach to enable the exploration of participants’ lived educational experiences (Connelly & Clandinin, 1990), using data collected from semi-structured interviews, critical incident reports, and a focus group. Analyses informed by narrative inquiry and grounded theory methodologies were used to look across data collected from participants to paint a rich chronicle of the participants’ stories.
      Findings highlight the pedagogy of care in conversation with notions of identity, belonging, and community, in order to note its significance for the more oft- studied aspects of teaching. This study contributes to research on teacher education and teaching and learning in higher education, and considers a different perspective on long-standing ideas about communities of practice.

description: Many thermodynamic properties of materials can be attributed to phonons and their interactions, also known as the Taylor series of the Born-Oppenheimer (BO) energy surface. In this the- sis, we present several novel approaches to computing phonons and their interactions, as well as implementations to predict thermodynamic properties of materials from phonons and phonon interactions. First, we implemented the symmetry analysis technique that allows us to write the Taylor series of the BO energy surface for a material at arbitrary order N using the space group irreducible derivatives, guaranteeing the symmetry of the crystal by construction. Second, we derived the minimum supercell multiplicity equation with which we can compute the smallest possible supercells that can accommodate N given wave vectors, greatly improving the computational efficiency for finite displacements calculations. Third, we implemented 2 branches of finite displacements methodologies, lone irreducible derivatives (LID) and bundled irreducible derivatives (BID), with the former sacrificing efficiency for accuracy and the latter emphasizing on using the least amount of calculations to extract all irreducible derivatives. Additionally, we implemented algorithms to predict materials properties including Grüneisen parameters, phonon linewidth, phonon frequency shift and thermal conductivity using our space group irreducible derivatives. We applied our methods on a wide range of materials, and the comparison against literature demonstrated massive gain on efficiency while maintaining high quality results.

Subjects: subject: Population forecasting Burma

description: Most countries in the world endeavour to develop their society and economy by means of short and long-term plans. In attempting to do this, information on the current and future size of the population and its age-sex distribution play an important role. Population projections are thus essential tools for development planning. In this study, an attempt has been made to project the population size and age-sex structure of Burma for a thirty year period from 1983 to 2013. The information provided by the 1983 census is used as basic data even though it has some limitations. To describe the rough demographic trends of the country, the data from annual vital statistics reports are also utilized. There are six chapters in this study. In Chapter I, the geographic and demographic backgrounds, of Burma are viewed. Chapter II is an analysis of the 1983 census age-sex distribution by means of sex ratios and age accuracy indices. Adjusted and smoothed age-sex data are obtained by three methods. In Chapter III, the three components of population growth: mortality; fertility and migration are examined. It is found that Burma's mortality and fertility have declined over time. A high level of literacy, an increase in the singulate mean age at marriage (SMAM) and decrease in the proportion of married led to fertility decline. International migration is not significant in Burma. In Chapter IV, population projections are made using 3 mortality and 4 fertility assumptions. In Chapter V, the implications of the projected population are assessed. The effect of rapid population growth on the socio-economic sectors: agriculture; education; health and employment are evaluated. This study concludes that the higher the fertility, the greater the problems for socio-economic development in the country. Fertility control is desirable to prevent further economic deterioration in Burma.

In this paper, we construct a residual based a posteriori error indicator for QM/MM coupling approximations. We prove the reliability of the error indicator (upper bound of the true approximation error) and develop some sampling techniques for its efficient calculation. Based on the error indicator and Dörfler marking strategy, we design an adaptive QM/MM algorithm for crystalline defects and demonstrate the efficiency with some numerical experiments.

Thin-film Bulk Acoustic Resonators on Integrated Circuits for Physical Sensing Applications

Publisher: name: Columbia University
Year: 2012
Subjects: Electrical engineering

description: Merging chemical and biomolecular sensors with silicon integrated circuits has the potential to push complex electronics into a low-cost, portable platform, greatly simplifying system- level instrumentation and extending the reach and functionality of point of use technologies. One such class of sensor, the thin-film bulk acoustic resonator (FBAR), has a micron-scale size and low gigahertz frequency range that is ideally matched with modern complementary metal-oxide-semiconductor (CMOS) technologies. An FBAR sensor can enable label-free detection of analytes in real time, and CMOS integration can overcome the measurement complexity and equipment cost normally required for detection with acoustic resonators.
This thesis describes a body of work conducted to integrate an array of FBAR sensors with an active CMOS substrate. A monolithic fabrication method is developed, which allows for FBAR devices to be built directly on the top surface of the CMOS chip through post-processing. A custom substrate is designed and fabricated in 0.18 µm CMOS to support oscillation and frequency measurement for each sensor site in a 6×4 array. The fabrication of 0.8-1.5 GHz FBAR devices is validated for both off-chip and on-chip devices, and the integrated system is characterized for sensitivity and limit of detection. On-chip, parallel measurement of multiple sensors in real time is demonstrated for a quantitative vapor sensing application, and the limit of detection is below 50 ppm. This sensor platform could be used for a broad scope of label-free detection applications in chemistry, biology, and medicine, and it demonstrates potential for enabling a low-cost, point of use instrument.

description: Previous spectral energy distribution modeling based on XMM-Newton X-ray observation of the classical double-lobed radio galaxy 3C 411 left the possibility open for the presence of a blazar-like core. We investigated this scenario by characterizing the radio brightness distribution in the inner ~10-pc region of the source. We applied the very long baseline interferometry (VLBI) technique at four different frequencies from 1.7 to 7.6 GHz. We analyzed archival data from the Very Long Baseline Array (VLBA) taken in 2014, and data from the European VLBI Network (EVN) obtained in 2017. The VLBI images reveal pc-scale extended structure in the core of 3C 411 that can be modeled with multiple jet components. The measured core brightness temperatures indicate no Doppler enhancement that would be expected from a blazar jet pointing close to the line of sight. While there is no blazar-type core in 3C 411, we found indication of flux density variability. The overall morphology of the source is consistent with a straight jet with ~50° inclination angle at all scales from pc to kpc.

description: We discuss the underlying relativistic physics which causes neutron stars to compress and collapse in close binary systems as has recently been observed in numerical (3+1) dimensional general relativistic hydrodynamic simulations. We show that compression is driven by velocity-dependent relativistic hydrodynamic terms which increase the self gravity of the stars. They also produce fluid motion with respect to the corotating frame of the binary. We present numerical and analytic results which confirm that such terms are insignificant for uniform translation or when the hydrodynamics is constrained to rigid corotation. However, when the hydrodynamics is unconstrained, the neutron star fluid relaxes to a compressed nonsynchronized state of almost no net intrinsic spin with respect to a distant observer. We also show that tidal decompression effects are much less than the velocity-dependent compression terms. We discuss why several recent attempts to analyze this effect with constrained hydrodynamics or an analysis of tidal forces do not observe compression. We argue that an independent test of this must include unconstrained relativistic hydrodynamics to sufficiently high order that all relevant velocity-dependent terms and their possible cancellations are included.

description: This thesis examines a group of Japanese words which express emotion, at the heart of which is the concept of amae , the desire for love and attention from another person. The emotions expressed by the words discussed herein are common to all human beings and form the core of all cultures. It seems that human feelings of fondness vary, depending on the depth of the relationship existing between the people concerned. It is in the expression of these emotions that peoples differ. It is suggested that the differences are not in the way people feel, but in the way their culture conditions them to behave in communicating their feelings.

description: Despite calls by U.S. researchers and policymakers for more teachers of color, supported by research documenting the significant social, emotional, and academic benefits of having same-race and same-ethnicity teachers, teaching remains an overwhelmingly White profession, even in light of demographic shifts rendering children of color the numeric majority in U.S. pre/schools. Relatedly, even as over one-fourth of children in the U.S. are immigrants, immigrant and transmigrant teachers have been marginalized in teacher education. Seeking to address this problem from a political-ideological paradigmatic perspective, this study sought to learn from transmigrant teachers’ negotiations of identities and practices. Rejecting essentialized notions of immigrant teachers/communities and focusing on Chinese transmigrant teachers teaching Chinese immigrants and children of immigrants, it sought to understand how they negotiated their teacher identities and pedagogical practices in light of occupational, geographical, and migrational intersections of identities and experiences. Further, it sought to document how these were enacted in early childhood public school classrooms. Situated in New York City, home to the largest Chinese and Chinese-American population of any city outside Asia, this collective case study centered the voices, identities, and experiences of three Chinese transmigrant early childhood teachers via Thirdspace theory, bridging identity, and transnational funds of knowledge. Doing so accounted for their individuality and collectivity. Analytically, • Thirdspace theory was used to map how they reconciled transnational identities, experiences, and pedagogical practices in the classroom; • bridging identity helped deepen understandings of how they constructed a professional/occupational identity influenced by, but not limited to, past biographical experiences; and • transnational funds of knowledge epitomized their lived experiences resulting from transnational navigations and/or belonging to transnational communities, capturing the complex flow of knowledges that characterized their experiences and pedagogies. Findings shed light onto the power and potential of Chinese transmigrant early childhood teachers in the education of Chinese immigrant children. Implications underscore the need for teacher education to learn from the experiences of international teacher candidates, recognizing how they may serve as role models for all students while improving the outcomes and school experiences of immigrant students, leveraging the simultaneity of experiences, identities, and experiences in the construction of Thirdspace classrooms.

description: Cognitive diagnosis assessment is a fundamental and crucial task for student learning. It models the student-exercise interaction, and discovers the students' proficiency levels on each knowledge attribute. In real-world intelligent education systems, generalization and interpretability of cognitive diagnosis methods are of equal importance. However, most existing methods can hardly make the best of both worlds due to the complicated student-exercise interaction. To this end, this paper proposes a symbolic cognitive diagnosis~(SCD) framework to simultaneously enhance generalization and interpretability. The SCD framework incorporates the symbolic tree to explicably represent the complicated student-exercise interaction function, and utilizes gradient-based optimization methods to effectively learn the student and exercise parameters. Meanwhile, the accompanying challenge is that we need to tunnel the discrete symbolic representation and continuous parameter optimization. To address this challenge, we propose to hybridly optimize the representation and parameters in an alternating manner. To fulfill SCD, it alternately learns the symbolic tree by derivative-free genetic programming and learns the student and exercise parameters via gradient-based Adam. The extensive experimental results on various real-world datasets show the superiority of SCD on both generalization and interpretability. The ablation study verifies the efficacy of each ingredient in SCD, and the case study explicitly showcases how the interpretable ability of SCD works.

description: We study classical solutions in Berenstein-Maldacena-Nastase (BMN) matrix model. A supersymmetric (1/2 BPS) fuzzy sphere is one of the classical solutions and corresponds to a giant graviton. We also consider other classical solutions, such as non-supersymmetric fuzzy sphere and harmonic oscillating gravitons. Some properties of oscillating gravitons are discussed. In particular, oscillating gravitons turn into usual supergravitons in the limit mu -> 0. Moreover, we calculate the one-loop effective action around the supersymmetric fuzzy sphere by the use of the background field method and show the quantum stability of the giant graviton. Also, the instability of the non-supersymmetric fuzzy sphere is proven.

description: We present the final distance measurements for the 2MASS Tully-Fisher (2MTF) survey. The final 2MTF catalogue contains 2,062 nearby spiral galaxies in the CMB frame velocity range of 600 km s$^{-1}$ $< cz < 10,000$ km s$^{-1}$ with a mean velocity of 4,805 km s$^{-1}$. The main update in this release is the replacement of some archival HI data with newer ALFALFA data. Using the 2MTF template relation, we calculate the distances and peculiar velocities of all 2MTF galaxies. The mean uncertainties of the linear distance measurements are around 22\% in all three infrared bands. 2MTF measurements agree well with the distances from the Cosmicflows-3 compilation, which contains 1,117 common galaxies, including 28 with SNIa distance measurements. Using distances estimated from the `3-bands combined' 2MTF sample and a $χ^2$ minimization method, we find best-fit bulk flow amplitudes of $308 \pm 26$ km s$^{-1}$, $318 \pm 29$ km s$^{-1}$, and $286 \pm 25$ km s$^{-1}$ at depths of $R_I = $ 20, 30 and 40 $h^{-1}{\rm Mpc}$, respectively, which is consistent with the $Λ$CDM model and with previous 2MTF results with different estimation techniques and a preliminary catalogue.

description: Aerial field robotics research represents the domain of study that aims to equip unmanned aerial vehicles - and as it pertains to this chapter, specifically Micro Aerial Vehicles (MAVs)- with the ability to operate in real-life environments that present challenges to safe navigation. We present the key elements of autonomy for MAVs that are resilient to collisions and sensing degradation, while operating under constrained computational resources. We overview aspects of the state of the art, outline bottlenecks to resilient navigation autonomy, and overview the field-readiness of MAVs. We conclude with notable contributions and discuss considerations for future research that are essential for resilience in aerial robotics.

description: Computing centres, including those used to process High-Energy Physics data and simulations, are increasingly providing significant fractions of their computing resources through hardware architectures other than x86 CPUs, with GPUs being a common alternative. GPUs can provide excellent computational performance at a good price point for tasks that can be suitably parallelized. Charged particle (track) reconstruction is a computationally expensive component of HEP data reconstruction, and thus needs to use available resources in an efficient way. In this paper, an implementation of Kalman filter-based track fitting using CUDA and running on GPUs is presented. This utilizes the ACTS (A Common Tracking Software) toolkit; an open source and experiment-independent toolkit for track reconstruction. The implementation details and parallelization approach are described, along with the specific challenges for such an implementation. Detailed performance benchmarking results are discussed, which show encouraging performance gains over a CPU-based implementation for representative configurations. Finally, a perspective on the challenges and future directions for these studies is outlined. These include more complex and realistic scenarios which can be studied, and anticipated developments to software frameworks and standards which may open up possibilities for greater flexibility and improved performance.

description: The saving of raw materials plays a major role in industry and is becoming increasingly important. In the field of cutting technology, the aim is to maximise practices such as the substitution of coolant and the steady increase of tool life in order to make an effective contribution towards environmental protection. Concerning the saving of coolant and to enhance the performance in dry machining a milling tool with a closed internally cooled system was developed. Heatpipes are applied which ensure improved heat dissipation from the cutting edge because of their excellent thermal conductivity. The dissipated heat is subsequently delivered to the surroundings via a heat sink. This contribution describes how the performance of a standard tool can be enhanced by the integration of a closed internally cooled system. Simulations of the heat distribution in the tool have been conducted to design and optimise the prototype. Hence, milling tests on duplex steel and temperature measurements in the cutting process have been carried out to verify and further optimise these simulation results.
Semiclassical Non-Trace Type Formulas for Matrix Element Fluctuations and Weighted Densities of States

description: Densities of states weighted with the diagonal matrix elements of two operators A and B, i.e., rho^(A,B)(E) = sum_n delta(E-E_n) cannot, in general, be written as a trace formula, and therefore no simple extension of semiclassical trace formulas is known for this case. However, from the high resolution analysis of quantum spectra in the semiclassical regime we find strong evidence that weighting the delta-functions in the quantum mechanical density of states with the product of diagonal matrix elements, , is equivalent to weighting the periodic orbit contributions in the semiclassical periodic orbit sum with the product of the periodic orbit means, _p_p, of the classical observables A and B. Results are presented for the hydrogen atom in a magnetic field for both the chaotic and near-integrable regime, and for the circle billiard.

description: This work will explore what it means to be a part of society. A society in which those that participate are deemed Human and those that are rejected from society are non-Human. This project reasons that rights are only afforded to those whom society determines are worthy of rights, Humans. From the black American context we question whether it is the case that our global society renders beings as Human or non-Human through the use of violence.

description: We study the evolution of non-linear spherically symmetric inhomogeneities in string cosmology. Friedmann solutions of different spatial curvature are matched to produce solutions which describe the evolution of non-linear density and curvature inhomogeneities. The evolution of bound and unbound inhomogeneities are studied. The problem of primordial black hole formation is discussed in the string cosmological context and the pattern of evolution is determined in the pre- and post-big-bang phases of evolution.

description: The Conservative party ruled Colombia from 1886 to 1930. During this period, a coterie of grammarians, poets, and theologians consolidated political power by appealing to literature as a form of rhetorical expertise. The Liberal party took power in 1930 and would hold it until 1946. Recent scholarship has argued that during this period Liberal intellectuals defended the political authority of literary expertise even as they endorsed a modernizing program. Although these charges of hypocrisy are well founded, they tell a limited version of the history of the so-called Liberal Republic, failing to take into full account the work of intellectuals at the edges of the Liberal party’s patronage network. This dissertation considers a series of writer-journalists—including Luis Vidales, Luis Tejada, José Antonio Osorio Lizarazo, José Joaquín Jiménez, and Arnoldo Palacios—who were active in Bogotá between 1920 and 1950. It examines their essays, chronicles, novels, and poems in newspapers and magazines, and less often in books, to argue that they elaborated a new function for literature in Colombia, appealing to the genres of urban journalism and the emerging discipline of urban sociology in order to transform literature into a form of social investigation.
