description: The cyclic deformation behavior of extruded Mg-8.5wt.%Al alloy with a conventional extrusion texture and a modified texture is systematically investigated by in-situ neutron diffraction and elastic viscoplastic self-consistent (EVPSC) modeling incorporating a twinning/de-twinning (TDT) scheme. The role of twinning and de-twinning on the deformation behavior of Mg-8.5wt.% Al alloy is investigated in terms of the macroscopic stress-strain response, the evolution of the activities of various deformation mechanisms, the texture evolution, the evolution of the internal elastic strains, and the evolution of the diffraction peak intensities. The alloy with the conventional extrusion texture undergoes twinning during initial compression and de-twinning during reverse tension. The same alloy does not favor twinning during initial tension, but rather during reverse compression. The alloy with a modified texture undergoes twinning during initial tension followed by detwinning during reverse compression. The results provide insights into the effect of initial texture, loading path, slip, twinning, de-twinning on the cyclic behavior of magnesium.

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: We compare surface metrics for shape optimization problems with constraints, consisting mainly of partial differential equations (PDE), from a computational point of view. In particular, classical Laplace-Beltrami type based metrics are compared with Steklov-Poincaré type metrics. The test problem is the minimization of energy dissipation of a body in a Stokes flow. We therefore set up a quasi-Newton method on appropriate shape manifolds together with an augmented Lagrangian framework, in order to enable a straightforward integration of geometric constraints for the shape. The comparison is focussed towards convergence behavior as well as effects on the mesh quality during shape optimization.

Subjects: subject: Landscape architecture

description: A very significant element of the city of Washington D.C. are its rivers. These rivers have been supporting the civilization around them for years. The Anacostia river has been subject to industrialization for centuries and it has been exposed to pollution mainly due to urban waste and storm water runoff. This pollution not only affects the water quality of the river but also impacts the nearby population, aquatic life and other species in many harmful ways. It is essential that development should take place considering the needs of people as well as the environment. Here, application of various green infrastructure techniques plays an important role in creating a balance. This thesis is an effort towards improving the water quality of the Anacostia River, reconnecting the city to its river and ensuring a healthy environment for humans and other dependent species.

description: Vortex breakdown occurs in many flow applications such as weather, aerodynamics, swirl combustors, and more, introducing unsteadiness that is often undesired. While vortex breakdown has been previously investigated extensively, researchers have struggled to efficiently characterize these flows due to the flow sensitivity to intrusive probes, and there is no real consensus regarding the process and reason of its formation. Recently, researchers have discovered the blue whirl, a silent and efficient flame which they believe is a mode of vortex breakdown, and suggested mechanisms of stabilization and prevention of it through temperature control. This thesis uses modern time-resolved measurement techniques to investigate breakdown at smaller temporal and spatial scales than previously researched, and shows the effect of heat addition at the inflow of a vortex generator on the onset and behaviour of breakdown modes. Smoke flow visualization experiments were preformed to identify heating and swirl rate effects on vortex flow, and the resulting swirl angle of the flow was measured. Decreasing the incoming swirl was found to delay or fully suppress the formation of a breakdown bubble. Increasing the inlet temperature had a similar effect due to the buoyancy effects on the flow increasing the axial velocity thus reducing the effective swirl. 3D Particle Tracking Velocimetry was used to obtain time-resolved flow fields of the vortex flow and breakdown with and without heating. Individual velocity profiles and velocity fields are presented, showing that flow behavior is dependent on much smaller scales than previously researched. Proper Orthogonal Decomposition is used to isolate energetically dominant modes and determine whether higher order modes are significant to the flow.

description: We construct equilibrium configurations of uniformly rotating neutron stars for selected relativistic mean-field nuclear matter equations of state (EOS). We compute in particular the gravitational mass ($M$), equatorial ($R_{\rm eq}$) and polar ($R_{\rm pol}$) radii, eccentricity, angular momentum ($J$), moment of inertia ($I$) and quadrupole moment ($M_2$) of neutron stars stable against mass-shedding and secular axisymmetric instability. By constructing the constant frequency sequence $f=716$ Hz of the fastest observed pulsar, PSR J1748-2446ad, and constraining it to be within the stability region, we obtain a lower mass bound for the pulsar, $M_{\rm min}=[1.2$-$1.4] M_\odot$, for the EOS employed. Moreover we give a fitting formula relating the baryonic mass ($M_b$) and gravitational mass of non-rotating neutron stars, $M_b/M_\odot=M/M_\odot+(13/200)(M/M_\odot)^2$ [or $M/M_\odot=M_b/M_\odot-(1/20)(M_b/M_\odot)^2$], which is independent on the EOS. We also obtain a fitting formula, although not EOS independent, relating the gravitational mass and the angular momentum of neutron stars along the secular axisymmetric instability line for each EOS. We compute the maximum value of the dimensionless angular momentum, $a/M\equiv c J/(G M^2)$ (or "Kerr parameter"), $(a/M)_{\rm max}\approx 0.7$, found to be also independent on the EOS. We compare and contrast then the quadrupole moment of rotating neutron stars with the one predicted by the Kerr exterior solution for the same values of mass and angular momentum. Finally we show that, although the mass quadrupole moment of realistic neutron stars never reaches the Kerr value, the latter is closely approached from above at the maximum mass value, as physically expected from the no-hair theorem. In particular the stiffer the EOS is, the closer the Kerr solution is approached.

description: The ekpyrotic phase (a slow contraction cosmic phase before the current expansion phase) manages to solve the main problems of the standard cosmology by means of a scalar field interpreted as a cosmic fluid in the Friedmann equation. Moreover, this phase generates a nearly scale-invariant spectrum of perturbations in agreement with the latest data. Then, the ekpyrotic mechanism is a serious possibility to the inflationary model. In this work, by using the approach of deforming metrics at linear level, we point out that it is impossible to generate a black hole with spherical symmetry supported by an isotropic fluid in this cosmological scenario.

Theory of nuclear spin dephasing and relaxation by optically illuminated nitrogen-vancy center

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)

description: Dephasing and relaxation of the nuclear spins coupled to the nitrogen-vacancy (NV) center during optical initialization and readout is an important issue for various applications of this hybrid quantum register. Here we present both an analytical description and a numerical simulation for this process, which agree reasonably with the experimental measurements. For the NV center under cyclic optical transition, our analytical formula not only provide a clear physics picture, but also allows controlling the nuclear spin dissipation by tuning an external magnetic field. For more general optical pumping, our analytical formula reveals significant contribution to the nuclear spin dissipation due to electron random hopping into/out of the $m=0$ (or $m=\pm1$) subspace. This contribution is not suppressed even under saturated optical pumping and/or vanishing magnetic field, thus providing a possible solution to the puzzling observation of nuclear spin dephasing in zero perpendicular magnetic field [M. V. G. Dutt \textit{et al}., Science \textbf{316}, 1312 (2007)]. It also implies that enhancing the degree of spin polarization of the nitrogen-vacancy center can reduce the effect of optical induced nuclear spin dissipation.
A Path to Peace or Oppression? The Anti-Normalization Movement in Palestine and Israel
Creators: name: Gooding, Thomas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In order to understand the controversy of peace, to explore the topic of anti-normalization, I developed a series of research questions and outlined the critical steps necessary to answer each one: What are definitions and interpretations of anti-normalization? What is the impetus behind the movement? Do joint Israeli-Palestinian
peace initiatives perpetuate oppression, and, if so, how? How is the anti-normalization
movement executed? What are the implications of anti-normalization with respect to
peace-building? Each of these questions provides a platform upon which I can contribute new knowledge about the anti-normalization movement and analyze its impact on reshaping
the paradigm of peace in Israel and Palestine. In order to answer these research questions, I interviewed Palestinian peace activists, directors of joint peace organizations in both Israel and Palestine, members of institutions affiliated with anti-normalization, and Palestinian academics. These individuals offered different perspectives based on their professional positions, affiliations, and personal identities; therefore, they provided a holistic, comprehensive representation of anti-normalization as a movement. During the research process, I interviewed these participants through face-to-face meetings in Israel and Palestine, Skype interviews, and telephone calls. Each interview lasted between 30 minutes and one hour. In order to identify these organizations, I first consulted with the Alliance for Middle East Peace, based in Washington, D.C., which supports joint peace initiatives in Israel and Palestine. I then used my initial connections to make new ones: One interviewee would suggest I meet with another. From there, I gained a better grasp of Palestinian and Israeli civil society and could thus research organizations on my own to identify additional interviewees. In addition to conducting interviews, I gathered data on the anti-normalization movement through newspaper editorials, online publications, and public documents from institutions affiliated with anti-normalization, particularly the Palestinian Academic and Cultural Boycott of Israel, and from joint peace programs. These documents included lists of demands and explanations for the reasons of these demands, specific descriptions of what constitutes normalization and the nuanced forms it takes, and responses to misconceptions about the movement or the movement’s demands. In addition, I explored the existing literatures on a history of Palestinian oppression and its impact on collective identity, an examination of Palestinian armed and nonviolent resistance, and an overview of the institutions, strategies, and movements that form the foundation of anti-normalization.
Chasing the White Rabbit in Tokyo: 100 Years of Alice in Japan

description: Alice appears everywhere in Japan, from Lolita dress prints to Disney
princess keychains, and even in manga. This thesis analyzes representations
of Alice across time in the Japanese imagination. The first chapter explores
the translation of Alice’s Adventures in Wonderland into Japanese,
ultimately concluding that there are at least 2 Alice types visible within
Japanese translations: the Meiji Alice and the Disney Alice. The second
chapter considers manga as yet another avenue for Alice adaptation,
exploring two mid-2000s manga that present contrasting takes on Alice’s
identity. This chapter also considers the implications of a Gothic or Dark
Alice, concluding that this type of Alice is nearly absent in the Western
imaginary. The third chapter explores what it means to perform Alice in the
everyday and in street fashion, finding that many Lolitas define Alice as a
symbol of cute, and do not attach any shame to this lack of substance. At this
point I incorporate data from informal interviews conducted in the summer
of 2016 with students at Kanda University in Chiba, as well as with Lolitas
in Harajuku, Tokyo.
I conclude that the Japanese Alice is almost a stranger to Carroll’s.
She has a darker side found in Kanai Mieko’s well-known 1972 short story
“Rabbits” and contemporary Gothic Lolita fashion, as discussed in chapter 2.
Notably, the parts of Carroll’s Alice story that evade direct translation into
Japanese are often omitted, so that her Wonderland becomes simpler and
very much a part of kawaii culture. This forms the backbone of the pure
kawaii Alice of chapter 3 who is just an icon of cute, which may not be such
a bad thing. This thesis argues that Alice splinters off into at least five “sub-
Alices”: a Meiji Alice, a noir Alice, a male Alice, a pure kawaii Alice, and a
Disney Alice, each with a unique Japanese-ness.

description: Evaluation of link prediction methods is a hard task in very large complex networks because of the inhibitive computational cost. By setting a lower bound of the number of common neighbors (CN), we propose a new framework to efficiently and precisely evaluate the performances of CN-based similarity indices in link prediction for very large heterogeneous networks. Specifically, we propose a fast algorithm based on the parallel computing scheme to obtain all the node pairs with CN values larger than the lower bound. Furthermore, we propose a new measurement, called self-predictability, to quantify the performance of the CN-based similarity indices in link prediction, which on the other side can indicate the link predictability of a network.

description: Research suggests that Black female students need safe spaces where they can share their feelings on race, gender, and self-concept without judgement (Muhammed,2012; Muhammad & Behizadeh, 2015). Black girls continue to use writing and other forms of literacy to challenge negative images, stereotypes, and the brutality they face in society and in schools (Griffin, 2020). However, research shows that the opportunities of Black girls to freely engage in literacy and identity exploration is limited (Dennis et al., 2021; Muhammad, 2012, 2015). This research seeks to understand how young Black girls explore their multilayered identities through multi-modal literacy. I explore components of Youth Participatory Action Research (YPAR) and components of Black feminist thought in this case study to answer the following research questions: 1. How do Black girls in a diverse after school program articulate their literacy and identity through multimodal artifact creation and artist statements? 2. How do the girls use a community exhibition of their artifacts and statements as acts of counter storytelling about their literacy and identity? This study focuses on Black female participants in an elementary afterschool program facilitated by me and my high school co-researchers. After creating a digital vision board of their interests and hopes for the future, curriculum lessons are tailored to those interests. Research concluded with a community exhibition of the girls’ artifacts to challenge the perceptions of Black girlhood. Analysis of the data indicates that the girls illuminated the tenets of Black feminist thought as they engaged with one another and composed multimodal artifacts. The girls’ artist statements and the community exhibition served as opportunities for the girls to present counter-narratives of Black girlhood. The young ladies in this study used literacy counter predetermined ideas of Black girlhood and create artifacts that were authentic to their Black girl identity. I will also show how dialogue is not only its own finding, but it is interwoven throughout the other findings to share knowledge, demonstrate ethics of caring and personal accountability. The study concludes that teachers and schools need to find opportunities for Black girls to explore and examine their identities in spaces that are void of judgment and criticism. Researchers who conduct YPAR studies need to be diligent in managing power structures by creating relationships with youth researchers and work to build their capacity as researchers.

description: Background: The main objective was to investigate the Socio-demographic, clinical, and side effect profile of patients on clozapine from Mental Health Hospital, Taif, Saudi Arabia. This article reports on an observational study. Clozapine is a second-generation atypical antipsychotic used as the drug of choice for the treatment resistant psychosis. It is supposed to be a baseline study from which we will get and understand rate of clinical, and side effect profile of the clozapine taking patients. Physicians, particularly psychiatrists are not only ignoring but also not aware, alert, so they always need to be watchful to the fatality of the drug, and take appropriate therapeutic measures. The aim was to study the socio-demographic status, clinical profile, comorbidity, side effects and outcome of patients treated with clozapine. Methodology: We reviewed all the indoor psychiatric patients of Mental Health Hospital, Taif, Saudi Arabia, from the period of one year between January 2021 to January 2022 (N=29). Our study design focused on prospective and observational studies. Descriptive statistical analysis was explored, and presented as frequencies, and percentages. We also determined crude rates for all adverse outcomes of clozapine. Results: We did a nearly mean follow-up of one year. The majority of patients were male (n=26; 89.65%), with a maximum being unmarried (n=16; 55.17%). Most patients belong to nuclear families due to cultural restrictions in this country (n=23; 79.31%). Among the literacy rate illiterate were (n=2; 6.89%, and unemployed (n=23; 79.31%). Among the study populations, the majority of respondents were found to have treatment-resistant schizophrenia (n=18; 62.06%), and around 79.31% of patients took more than two antipsychotics in adequate doses. Among side effect profiles most of the patients suffered hyper-salivation (n=19; 65.51%), sedation (n=12; 41.37%), and rarely suffered from agranulocytosis. Conclusion: Socio-demographic, clinical, and side effect profiles were the significant indicators of clozapine. Clozapine has been used for treatment-resistant psychosis, but due to fatal side effect profile we used it cautiously. In our study, we found that myocarditis, hematemesis, and leukocytosis, and neutropenia are fatal side effects of clozapine. We also found hyponatremia-induced seizure. The prevalence of blood dyscrasias in our study is rarely seen. Hyper-salivation is the most common side effect reported. Majority of the patients in our study were male, and treatment resistant Schizophrenia was the most common diagnosis. Myocarditis is life-threatening side effect seen in our study
ChIP-Seq and RNA-Seq for PPARγ in Human Urothelial-Derived Cell Lines

Cancer cell gene regulation

description: Bladder cancer has a high prevalence throughout the world, primarily affecting men over the age of 55. Despite having multiple treatment options, such as chemotherapy, radiation, and surgery, bladder cancer has a high recurrence rate in patients. Consistent with other cancer types, understanding the molecular mechanism of bladder cancer has the potential to increase the number and type of treatment options available to patients. Upregulation of the transcription factor (TF), PPARγ, has been associated with the metastasis of bladder cancer, but this mechanism is not clearly understood. To gain additional information on this mechanism, we conducted both a ChIP-Seq and RNA-Seq analysis on three bladder cancer cell lines (UMUC1, SW780, and 5637) after treatment with a PPARγ agonist, rosiglitazone (RZ). The goal of this analysis is to identify genome-wide binding sites and genes regulated by PPARγ within these cell lines. We determined that RZ reduced the number of PPARγ binding sites in the three bladder cancer cell lines. Additionally, there were no PPARγ motifs bound by PPARγ regardless of cell or treatment type. The RNA-Seq results suggest that RZ affects gene expression within UMUC1 and SW780 cell lines but not 5637. Furthermore, GSEA identified numerous differentially expressed biochemical pathways in the UMUC1 and SW780 cell lines. G2M checkpoint and E2F target gene sets were downregulated within RZ-treated UMUC1 and SW780 cells but not 5637. The downregulation of these mechanisms may play an essential role in PPARγ’s involvement in bladder cancer metastasis. How PPARγ is involved in bladder cancer metastasis is still unknown; however, these results provide additional insight into this mechanism.

Thus, we examine the production of entropy in a pion gas, particularizing to inhomogeneities of the temperature, for which we benefit from the known thermal conductivity. We finally put that entropy produced in relaxing such thermal inhomogeneities in the broad context of this relatively unexplored phase of early-universe cosmology.

description: In alignment with the Affordable Care Act of 2010, non-profit hospitals must complete a Community Health Needs Assessment (CHNA) every three years to collect data to prioritize health needs and implement strategies for improvement. The purpose of the internship was to identify and demonstrate health care leader (HCL) skills necessary to effectively implement the CHNA process including data collection, evaluation, and implementation of programming. Literature review supports that nurse involvement is essential to include in community health planning, and the HCL has a unique opportunity to use graduate competencies to advocate for community health promotion. The internship took place within an organization designed specifically as a partnership between the local health department and local hospital to conduct the CHNA. The internship provided opportunities to demonstrate HCL competencies such as knowledge of health policy, population health, knowledge of health care environment, and leadership with a focus on interagency collaboration. Internship activities included prioritization and implementation of CHNA data through creation of written and virtual resources, community outreach events, program development, and participation in interagency meetings. The internship examined the role of the health care leader (HCL) in the CHNA process, and how the expertise of advanced-degree nurses can improve the CHNA process. The experience provided the intern an opportunity to build upon the present role as a community health nurse, and to prepare for future opportunities in leadership roles and to lead effective interagency collaboration.

description: Many works related to Twitter aim at characterizing its users in some way: role on the service (spammers, bots, organizations, etc.), nature of the user (socio-professional category, age, etc.), topics of interest , and others. However, for a given user classification problem, it is very difficult to select a set of appropriate features, because the many features described in the literature are very heterogeneous, with name overlaps and collisions, and numerous very close variants. In this article, we review a wide range of such features. In order to present a clear state-of-the-art description, we unify their names, definitions and relationships, and we propose a new, neutral, typology. We then illustrate the interest of our review by applying a selection of these features to the offline influence detection problem. This task consists in identifying users which are influential in real-life, based on their Twitter account and related data. We show that most features deemed efficient to predict online influence, such as the numbers of retweets and followers, are not relevant to this problem. However, We propose several content-based approaches to label Twitter users as Influencers or not. We also rank them according to a predicted influence level. Our proposals are evaluated over the CLEF RepLab 2014 dataset, and outmatch state-of-the-art methods.

description: The tertiary gene pool of wheat includes wild relatives like Aegilops geniculata (UUMM, 2n=4x=28) that are valuable genetic reservoirs for novel abiotic and biotic resistance genes. However, modern wheat varieties share limited genomic commonality with these gene pool members presenting barriers to recombination and genetic mapping of desirable genes. We mapped a broad-spectrum leaf rust resistance gene Lr57 located on chromosome 5Mg of Ae. geniculata using a simple but powerful methodology for high-resolution genetic mapping in tertiary gene pool members of wheat. Five gene candidates were revealed all with possible defense related functions. Strategic application of differential expression analysis, Virus-Induced Gene Silencing, and mutagenesis analysis reduced the candidate gene of interest to a singular and novel ID-NLR resistance gene containg a protein kinase, NB-Arc, and LRR domain. Using multiple strategies, validation of Lr57 candidate was completed. Gene complementation by transformation of Lr57 candidate is currently being conducted.

description: We present equilibrium models of relativistic magnetised, infinite, axisymmetric jets with rotation propagating through an homogeneous, unmagnetised ambient medium at rest. The jet models are characterised by six functions defining the radial profiles of density, pressure, and the toroidal and axial components of velocity and magnetic field. Fixing the ambient pressure and the jet rest-mass density and axial components of the flow velocity and magnetic field, we analyze the influence of the toroidal magnetic field and several rotation laws on the structure of the equilibrium models. Our approach excludes by construction the analysis of the self-consistently magnetically launched jet models or the force-free equilibrium solutions. Several forbidden regions in the magnetic pitch angle/magnetization plane are found where models of the class considered in our study could not be settled. These forbidden regions are associated with the existence of maximum axial and toroidal magnetic field components compatible with the prescribed equilibrium condition at the jet surface, and/or an excess of centrifugal force producing gaps with negative pressures in the jet. The present study can be easily extended to jet models with different transversal profiles and magnetic field configurations. In the last part of the paper, we test the ability of our RMHD code to maintain steady equilibrium models of axisymmetric RMHD jets in one and two spatial dimensions. The one dimensional numerical simulations serve also as a consistency proof of the fidelity of the analytical steady solutions discussed in the first part of the paper. The present study allows us to build initial equilibrium jet models with selected properties for dynamical (and emission) simulations of magnetised relativistic jets with rotation.

description: In response to public concerns about exposure to pesticides, some state and local municipalities have placed restrictions on the use of pesticides on athletic fields. When such restrictions are implemented athletic field management often transitions to the use of natural or organic turf care with little understanding of how the transition away from conventional management practices may affect surface conditions and soil microbial properties.This thesis examined the use of organic and conventional management programs on the turf quality, surface hardness, and shear strength of engineered soil cap, hybrid bermudagrass (Cynodon dactylon x Cynodon transvaalensis) athletic fields, as well as the impact of the two programs on the rhizosphere microbiome. Turf quality was assessed by visual means and by obtaining normalized difference vegetative index (NDVI) readings of the turf canopy. Surface hardness was determined using a Clegg impact surface tester. The rotational shear strength of the surface was measured using a shear vane. The study was conducted for 3 years at two different locations; research plots at the University of Maryland Research Facility and on athletic fields at Laytonia Recreational Park, in Gaithersburg, MD. Surface property data was collected monthly. Turf visual quality and NDVI data revealed use of the organic management program led to higher visual quality during spring, which was primarily the result of the spring retention of fall overseeded intermediate ryegrass (Lolium x hybridum Hausskn) and early season use of natural based fertilizers. In the summer months, crabgrass (Digitaria ischaemum Schreb.) encroachment was limited to the organically managed turfgrass. At both locations, clover (Trifolium repens) encroachment developed by the third year of the study, but the presence of this weed had limited impact on turfgrass quality. There were few significant differences in surface hardness and shear strength between the two management practices over the entire study period. The rhizosphere microbiome data, which was collected 12, 20, and 24 months after the initiation of two programs, did not show any significant difference between the organic and conventional management athletic fields in microbial abundance and/or diversity. The results of this study emphasize that the adoption of organic management programs on bermudagrass athletic fields should, in most instances, center on the establishment of acceptable weed tolerance levels for these fields. The use of organic management programs in the transition zone offers a viable alternative to the conventional chemical management of athletic fields, however over time, growing weed seed banks may necessitate the need for the occasional use of conventional herbicide materials.

description: This thesis seeks to examine anti-expressway organizing by the Crest Street community in Durham, North Carolina as a case study of community organizing, specifically evaluating the role of community identity and informal cultural institutions as vital organizing platforms in the community’s success in maintaining Crest Street as a unified neighborhood. Through analyzing the function of community institutions such as the Crest Street Community Council and the New Bethel Baptist Church, this thesis will assess the role of Crest Street community members and their motivations. Relying on interviews with Crest Street activists, primary documents and archives, and secondary academic works this thesis will also place Crest Street in the context of the national transportation and housing policies and overarching social conditions of white supremacy that shaped Crest Street into the community it was before and after the battle for its survival. Finally, this thesis will discuss the future of Crest Street and its collective identity as a “family community,” as the neighborhood becomes increasingly diversified and integrated with greater Durham.

description: The purpose of this thesis is to explore the accuracy of fatigue damage estimation in printedwiring assembly (PWA) interconnects, using purely frequency-domain (also known as spectral) information such as the power spectral density (PSD) of the input excitation. The test case used in this study is the estimation of fatigue damage accumulation rate in the critical interconnects of low profile quad flat-pack (LQFP) components on a PWA, under broad-band random vibration excitation. this study examines whether the fatigue predictions made with this frequency-domain approach are consistent with those obtained from a direct time-domain approach. The frequency-domain response modeling is achieved using a two-stage global-local modeling process using a finite element model (in ABAQUS©), where the dominant modal participation factors for the dynamic response is obtained using a dynamic global simplified dynamic finite element model consisting of shell elements to represent the entire PWA. The PSD of the input excitation is applied as a boundary condition and the PSD of the PWA strain response is recorded at the base of critical components. The corresponding PSD for the dynamic strain response at critical interconnects is estimated with strain-transfer functions (STFs) for each dominant mode, obtained from detailed 3D quasi-static nonlinear local models of the component, adjacent PWB, and the interconnects. The global-local STF provides a relationship between the level of equivalent strain in the critical interconnects and the flexural strain at the adjacent surface of the PWB. The STF for each of the dominant vibration modes is obtained by imposing the corresponding mode-shape predicted by the dynamic global model on the PWB, in the quasistatic local model, using multi-point constraint equations. The PSD of the equivalent strain in the critical interconnect is then estimated via linear modal superposition. A deterministic estimate of the cyclic fatigue damage accumulation rate in the critical interconnect is then conducted with the Basquin high cycle fatigue (HCF) model and linear damage superposition approach, by using three different spectral approaches for representing the strain severity with estimated probability density functions (PDFs). The three approaches include: (i) Raleigh method; (ii) Dirlik method and (iii) Range distribution function created with the Rainflow cycle counting method. Methods (ii) and (iii) are derived from a pseudo time-history created with an inverse Fourier transform. These frequency-domain results are compared to corresponding fatigue damage estimates from a multi-modal time-domain analysis method, to assess the consistency of the two approaches.

description: Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from the Canada-France-Hawaii Telescope Stripe 82 Survey for galaxy clusters selected through their high signal-to-noise thermal Sunyaev-Zeldovich (tSZ) signal measured with the Atacama Cosmology Telescope (ACT). For a sample of 9 ACT clusters with a tSZ signal-to-noise greater than five the average weak lensing mass is $\left(4.8\pm0.8\right)\,\times10^{14}\,\mathrm{M}_\odot$, consistent with the tSZ mass estimate of $\left(4.70\pm1.0\right)\,\times10^{14}\,\mathrm{M}_\odot$ which assumes a universal pressure profile for the cluster gas. Our results are consistent with previous weak-lensing measurements of tSZ-detected clusters from the Planck satellite. When comparing our results, we estimate the Eddington bias correction for the sample intersection of Planck and weak-lensing clusters which was previously excluded.

Collaborative System Architecture & Innovation: How Networked Organizations Embed Creative Production

description: Organizational innovation, the process of generating value through addressing
problems in novel ways, has historically been an exclusive function of managerial
oligarchies. This paper will address how the constant demand to innovate in the modern
global economy, and the emergence of powerful communication networks, have together
led corporations to increasingly expand their search for new ideas beyond upper
management, turning their attention to the collective brainpower of their entire cohort of
employees. Whereas the first rudimentary suggestion box systems of the early 20th century
first allowed factory workers to contribute creatively in addition to their physical labor
power, organizations such as Pfizer and Whirlpool now utilize digital platforms to add
value to the company by collecting employee ideas while encouraging participation and
collaboration. The paper concludes with an analysis of the political economy of these
collective innovation systems. Are these networks leading to more democratic
organizations and happier, more engaged workers? Or, are they primarily extracting labor
power from employees in new ways, without equitably distributing the profits?
Topological Crystalline Superconductivity in Locally Non-centrosymmetric Multilayer Superconductors

description: Topological crystalline superconductivity in the locally non-centrosymmetric multilayer superconductors (SCs) is proposed. We study the odd-parity pair-density wave (PDW) state induced by the spin-singlet pairing interaction through the spin-orbit coupling. It is shown that the PDW state is a topological crystalline SC protected by a mirror symmetry, although it is topologically trivial according to the classification based on the standard topological periodic table. The topological property of the mirror subsectors is intuitively explained by adiabatically changing the BdG Hamiltonian. A subsector of the bilayer PDW state reduces to the two-dimensional non-centrosymmetric SC, while a subsector of trilayer PDW state is topologically equivalent to the spinless p-wave SC. Chiral Majorana edge modes in trilayers can be realized without Cooper pairs in the spin-triplet channel and chemical potential tuning.
