description: The Cauchy-Schwarz (CS) inequality -- one of the most widely used and important inequalities in mathematics -- can be formulated as an upper bound to the strength of correlations between classically fluctuating quantities. Quantum mechanical correlations can, however, exceed classical bounds.Here we realize four-wave mixing of atomic matter waves using colliding Bose-Einstein condensates, and demonstrate the violation of a multimode CS inequality for atom number correlations in opposite zones of the collision halo. The correlated atoms have large spatial separations and therefore open new opportunities for extending fundamental quantum-nonlocality tests to ensembles of massive particles.

Tumor necrosis factor alpha and non-inflammatory sensitization of masseter muscle nociceptors
Creators: name: Hakim, Akhlaq Waheed
Publisher: name: University of British Columbia
Year: 2011

description: Behavioral evidence in rats indicates that injection of tumor necrosis factor alpha (TNFalpha into skeletal muscle results in a prolonged mechanical sensitization without gross inflammation. The present series of studies were conducted to test the idea that injection of TNFalpha causes mechanical sensitization of skeletal muscle through a peripheral mechanism that involves lowering of the mechanical threshold (MT) of muscle nociceptors without inflammation. In- vivo extracellular electrophysiological recording was used to assess the effect of TNFalpha (1 or 0.1microgram) and other drugs on the excitability and MT of masseter muscle nociceptors. Expression of TNFR1 (P55) and TNFR2 (P75) receptors by the masseter muscle and trigeminal ganglion neurons that innervate that muscle was determined by Western blot and immunohistochemical methodologies, respectively. The Evans blue dye technique and thermal camera recordings were used to assess inflammation in muscle tissues. Enzyme-linked immunoassays and glutamate biosensor probes were used to measure muscle concentrations of prostaglandin (PG) E2 and nerve growth factor, and glutamate, respectively. Intramuscular injection of 1mg TNFalpha did not excite nociceptors, but did significantly decrease MT compared to vehicle control. There was no evidence of gross inflammation 3 hours after injection of TNFalpha. Co-injection of TNFalpha with P55 or P75 receptor antibodies attenuated TNFalpha-induced mechanical sensitization. P55 and P75 receptors were expressed by 29% and 62% of masseter nociceptors, respectively. PGE2 and glutamate concentrations were significantly changed 3 hours after TNFalpha injection into the masseter muscle. Injection of diclofenac, a cycloxygenase inhibitor that attenuates prostaglandin synthesis, partially reversed the TNFalpha-induced decreases in the MT of masseter muscle nociceptors, while vehicle control, DL-2-amino-5-phophonovaleric acid, a competitive NMDA receptor antagonist, and a tyrosine kinase A receptor antibody, which blocks NGF-induced masseter muscle nociceptor sensitization, did not significantly alter nociceptor MT. These findings indicate that TNFalpha-induced mechanical sensitization of masseter nociceptors is mediated, in part, by increased PGE2 levels through activation of peripheral P55 and P75 receptors. Over all, these results suggest that injection of TNFalpha into skeletal muscle could be used as a model of myofascial trigger points to study the peripheral pain mechanisms of masticatory muscle pain.

description: Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative therapy for hematologic malignancies. The most frequent indication is acute myeloid leukemia (AML). Relapse and graft-versus-host disease (GVHD) are the major causes of HCT failure. Most immunosuppressive drugs used for GVHD prophylaxis increase relapse, presumably due to inhibiting not only GVHD but also graft-versus-leukemia effect (GVL). Polyclonal rabbit anti-thymocyte globulin (ATG), now widely used for GVHD prophylaxis, is the only immunosuppressive drug reducing GVHD without increasing relapse. The reason for ATG not increasing relapse is not known. We hypothesized that this could be due to an anti-leukemic activity of ATG. I investigated the anti-leukemic activity both in vitro and in vivo (in patients). I first evaluated whether ATG at clinical concentrations kills leukemic blasts in vitro. I showed that ATG does kill leukemic blasts, via complement-dependent cytotoxicity (CDC) and direct induction of apoptosis. Next, I investigated whether ATG kills in vitro not only leukemic blasts but also leukemic stem cells (LSCs). I showed that ATG does kill LSCs, primarily via CDC, however, only at a higher concentration than needed for killing leukemic blasts. In spite of the anti-leukemic activity of ATG in vitro, in vivo ATG has so far been considered not to have an anti-leukemic activity as in 3/3 randomized studies ATG did not reduce relapse. We hypothesized that this could be due to differential effects of ATG pre- versus post-HCT. Specifically, we hypothesized that the direct anti-leukemic effect of ATG is countered by the anti-GVL effect of ATG post- but not pre-HCT. I evaluated associations between pre- versus post-HCT ATG area-under-the-curve (AUC) and relapse. I found that high pre-HCT AUC was associated with a low incidence of relapse. Conversely, there was a trend toward an association between high post-HCT AUC and a high incidence of relapse. The association between pre-HCT AUC and relapse is an indirect evidence for anti-leukemic activity of ATG in vivo. These findings are expected to lead to clinical studies harnessing the anti-leukemic effect of ATG, e.g., by dosing ATG so as to achieve a higher than conventional pre-HCT AUC and a conventional post-HCT AUC. This could lead to decreasing relapse without increasing GVHD which may lead to improved survival.

description: Mutation testing is a white-box fault-based software testing technique that applies mutation operators to modify program source code or byte code in small ways and then runs these modified programs (i.e., mutants) against a test suite in order to measure its effectiveness and locate the weaknesses either in the test data or in the program that are seldom or never exposed during normal execution. In this paper, we describe our implementation of a generic mutation testing framework and the results of applying three sets of concurrency mutation operators on four example Java programs through empirical study and analysis.

description: Marine Biodiversity Credits (MBCs) entail a natural capital accounting methodology that establishes comparable units of marine biodiversity value, which can be turned into credits or assets. This technical framework outlines the methodology for generating MBCs, which are designed to support both policy and financial applications. The framework is based on the concept of Biodiversity Units (BUs), which are defined as spatially and temporally coherent areas for marine biodiversity evaluation. Within each BU, Marine Biodiversity Units (MBUs) are calculated from a set of modulating factors (MFs) that capture the ecological and social value of marine biodiversity within the area of interest. The MFs are weighted and normalized to generate a single score for each MBU, which reflects its relative biodiversity value. The MBCs are generated without counterfactuals, as they reward maintaining a high baseline of biodiversity within each BU. The methodology includes a buffer that allows for some variability in the MBU scores, while ensuring that the credits are only issued to BUs that maintain a high level of biodiversity. The MBC framework is designed to be flexible and adaptable to different contexts, while ensuring scientific rigor and transparency. 
Applied to policy, this accounting methodology can help governments and decision makers base conservation efforts using data-driven ecological economics. More importantly, MBCs are designed to support diverse financial mechanisms. As natural capital assets, once properly issued, they can operate in mechanisms such as guarantees in conservation finance, nature-debt swaps, tradable commodities, or as backing for environmental derivatives and other securities. By providing a market-based mechanism for valuing and protecting marine biodiversity, MBCs have the potential to unlock new sources of funding and engage a wider range of actors in conservation efforts. This paper presents the technical details of the MBC framework and discusses its potential benefits and challenges.

description: This thesis examines the motivations of the Canadian Missionaries and Korean Protestants in in Hamgyeong Province (Northeastern Korea) and Gando (Southeastern Manchuria) as well as the influence they had on one another during the first two decades of the twentieth century. The analysis of Canadian motivations demonstrated that they were wholly consumed with building the mission and would do nearly anything to ensure that it succeed, including: working themselves to exhaustion, cooperating with Protestant nationalists, vigorously protesting against the Japanese colonial government's brutal suppression of the Koreans in 1919 and 1920 as well as capitulating to the demands of their constituency when they were forcefully expressed in the 1920s. The Korean Protestants wanted changes to be made to the educational and financial policies of the mission and some resorted to violence in an effort to spur the Canadians into action. The examination of Korean motivations shows that they gravitated toward the Church for a variety of reasons, one of the most salient being, their desire to reclaim their nation from the Japanese imperialists. The discussion of the influence that the Canadians had on the Koreans revealed, among other things, that their decision to work with, rather than against the nationalists, contributed to further radicalizing the Church, and their "women's work" helped to transform the nature of gender relations in Hamgyeong and Gando. The investigation of the Koreans showed that they too had much influence. The Canadians understood that they had to "do the bidding" of the Koreans for the mission to succeed, as is most clearly seen in their resolve to transform the mission in the 1920s. The study of the Canadians and Koreans in Hamgyeong and Gando enhances our understanding of the missionizer and the missionized in the overseas mission field by providing a different way of viewing the motivations of the former and emphasizing the agency and power of the latter; enriches our knowledge of Korean Christian history by revealing how and why the Canadians and Koreans built a distinct mission and Church; and illuminates the role that the Presbyterian Maritime Church played in the Canadian missionary movement.
Explicit solution for vibrating bar with viscous boundaries and internal damper

Year: 2011
Subjects: subject: Mathematical Physics (math-ph)

description: We investigate longitudinal vibrations of a bar subjected to viscous boundary conditions at each end, and an internal damper at an arbitrary point along the bar's length. The system is described by four independent parameters and exhibits a variety of behaviors including rigid motion, super stability/instability and zero damping. The solution is obtained by applying the Laplace transform to the equation of motion and computing the Green's function of the transformed problem. This leads to an unconventional eigenvalue-like problem with the spectral variable in the boundary conditions. The eigenmodes of the problem are necessarily complex-valued and are not orthogonal in the usual inner product. Nonetheless, in generic cases we obtain an explicit eigenmode expansion for the response of the bar to initial conditions and external force. For some special values of parameters the system of eigenmodes may become incomplete, or no non-trivial eigenmodes may exist at all. We thoroughly analyze physical and mathematical reasons for this behavior and explicitly identify the corresponding parameter values. In particular, when no eigenmodes exist, we obtain closed form solutions. Theoretical analysis is complemented by numerical simulations, and analytic solutions are compared to computations using finite elements.

Specifically, this article summarizes recent progress about tag-aware recommender systems, emphasizing on the contributions from three mainstream perspectives and approaches: network-based methods, tensor-based methods, and the topic-based methods. Finally, we outline some other tag-related works and future challenges of tag-aware recommendation algorithms.

description: Veterinary services are unavailable in many communities, which contributes to issues with human and animal health and well-being. Providing veterinary services in an evidence-based manner is important, but programs are rarely evaluated. The objectives of this research were to scope the literature to determine how subsidized veterinary services are evaluated in terms of impacts on animal and human health, followed by an evaluation of a decade-long program in the Sahtu Settlement Area of the Northwest Territories to understand the uptake and impact of annual services. Using methods commonly found in literature, a door-to-door survey, a dog census in each community, and a chart review of dog medical records from clinics in 2008-2018, were completed to evaluate community perspectives, the uptake of services, and changes in 7 dog population health and welfare measures over time. The number of owners and dogs attending clinics increased over time, as did the sterilization, vaccination and deworming of dogs, and dog body condition and age. Community differences, however, were evident in program reach, service uptake, dog husbandry practices, and community concerns about dogs. Results from this evaluation will improve future clinics and may guide programs in other underserved areas.
Characterization of fixed wireless channels for use in distribution automation networks

Publisher: name: University of British Columbia

description: Distribution Automation (DA) is the use of advanced communications network infrastructure in combination with intelligent power equipment and intelligent electronic devices (IEDs) in substations and on distribution feeders to monitor, protect and control the electrical power distribution network. Because wireless networks are generally less expensive, easier to deploy and more resilient than alternatives such as fibre-optic and power line carrier (PLC) networks, they have attracted considerable interest from DA network designers. However, designers must take careful account of the manner in which: 1) the useful range of the links between wireless devices impacts the formation of wireless networks, 2) the depth of fading varies across the range of frequencies available to power utilities for use in such networks, and 3) the degree of shadow fading varies as the height of wireless devices used in such networks rise from pedestrian to pole-top level. Here we show that: 1) the manner in which the distribution assets in BC Hydro's electrical power distribution network are geographically distributed affects the ease with which such assets can be formed into either conventional base-station-to-pole-top fixed wireless macrocell networks or pole-top-to-pole-top fixed wireless mesh networks, 2) the depth of fading experienced on fixed wireless macrocell channels is generally proportional to the carrier frequency and 3) the degree of shadow fading experienced on fixed wireless macrocell channels often increases as the terminal height is raised from pedestrian to pole-top level. These results will help power utilities design reliable and cost-effective wireless networks in support of DA.

description: Bibliography: p. 221-232
description: Current concern over the potentially negative impacts of climate change has brought attention to reduction of anthropogenic emissions of methane. Biofiltration of methane is an inexpensive technique to reduce emissions from point sources of methane arising from the production and transport of crude oil and natural gas. Optimization of the methane biofiltration technique can be achieved through laboratory experiments and long term field studies which are costly and time consuming. On the other hand, mathematical models, verified with laboratory and field data, can be a more cost effective method for generating the necessary information to understand the processes of methane biofiltration and to design and monitor methanotrophic biofilters. A three-dimensional mathematical model and a one-dimensional mathematical model were developed to analyze methanotrophic biofilters. Biological reactions, mass transport, heat transfer, and moisture transport were incorporated in both models. The models are capable of predicting concentration profiles of individual gases, moisture and temperature profiles, and percent oxidation of methane. Properties of porous medium and environmental data such as precipitation and ambient temperature are given as model inputs. Both models were calibrated and tested for laboratory and field conditions.

description: Count data with complex features arise in many disciplines, including ecology, agriculture, criminology, medicine, and public health. Zero inflation, spatial dependence, and non-equidispersion are common features in count data. There are currently two classes of models that allow for these features—the mode-parameterized Conway–Maxwell–Poisson (COMP) distribution and the generalized Poisson model. However both require the use of either constraints on the parameter space or a parameterization that leads to challenges in interpretability. We propose spatial mean-parameterized COMP models that retain the flexibility of these models while resolving the above issues. We use a Bayesian spatial filtering approach in order to efficiently handle high-dimensional spatial data and we use reversible-jump MCMC to automatically choose the basis vectors for spatial filtering. The COMP distribution poses two additional computational challenges—an intractable normalizing function in the likelihood and no closed-form expression for the mean. We propose a fast computational approach that addresses these challenges by, respectively, introducing an efficient auxiliary variable algorithm and pre-computing key approximations for fast likelihood evaluation. We illustrate the application of our methodology to simulated and real datasets, including Texas HPV-cancer data and US vaccine refusal data. Supplementary materials for this article are available online.

description: Real-world large-scale data collection poses an important challenge in the security field. Insider and masquerader attack data collection poses even a greater challenge. Very few organizations acknowledge such breaches because of liability concerns and potential implications on their market value. This caused the scarcity of real-world data sets that could be used to study insider and masquerader attacks. In this paper, we present the design, technical, and procedural challenges encountered during our own masquerade data gathering project. We also share some lessons learned from this several-year project related to the Institutional Review Board process and to user study design.

description: This study examined the experience of undergraduate research from the perspectives of students and professors at a Canadian university. Considering existing research on the topic, the study was conducted to expand understanding of the complexities of the undergraduate research experience. Specifically, research aims focused on exploring motivations for participation, student persistence with their research, conditions for undergraduate research, and impacts of undergraduate research on student learning and development. The mixed method design included a student survey and interviews with students and professors involved with undergraduate research. Findings suggest that professors are intrinsically motivated and students are both intrinsically and extrinsically motivated. For professors, motivations for participation came from their own experiences as students and educators, from rewards such as satisfaction, and from what they observed as positive learning impacts on students. For students, their motivations for participation in undergraduate research were primarily goal directed as well as the value­added factor to their educational experience. Relative benefits of contributions to student persistence varied in the study population by age, program, and whether the undergraduate research was a required component of their program. Based on survey results, the most important factor in students' persistence was that of guidance, such as directions and suggestions from professors and regular feedback about progress. This underscores the significance of the professor-student relationship in the undergraduate research experience. Qualitative results indicated that resources and culture were the most important conditions for effective undergraduate research. This finding was corroborated by results of the student survey as well. Findings from this study are consistent with existing research on the impacts of undergraduate research on student learning and development. Implications for professors and educational leadership are described, and specific recommendations are made to strengthen undergraduate research at the institution. While localized to one particular university, the findings are relevant to other education institutions for planning, implementing, and supporting high quality undergraduate research experiences that maximize student learning.

description: Approximately 25% of individuals worldwide will experience a common mental disorder (CMD) in their lifetime, and previous studies have suggested that poor maternal mental health (MMH) is associated with negative child health and development outcomes. However, these studies use individual markers to represent overall child health status. An allostatic load (AL) index may provide a better understanding of overall health status by pooling together multiple markers of intermediary risk to poor health outcomes. Here, I tested for an association between the following variables in a cross-sectional sample of maternal-child dyads from rural Nicaragua: 1) MMH and individual child health measures. 2) MMH and a child AL index. Multiple regression analyses found no significant relationships between MMH and any of the outcome measures. However, a high prevalence of probable cases of CMDs (30.9%) was documented among mothers, indicating that mental health should be prioritized by local and regional health interventions.
The effects of gonadotropin releasing hormone-I and II in human granulosa cells
Creators: name: Hong, In-Sun
Publisher: name: University of British Columbia
Year: 2011

description: Gonadotropin-releasing hormone (GnRH) is the key regulator of hypothalamus-pituitary gonadal function. In the anterior pituitary, GnRH stimulates the synthesis and the release of the gonadotropins. GnRH and its receptors have also been found in extra pituitary tissues such as the ovary, breast, and placenta. GnRH has been reported to have antiproliferative effects on granulosa cells from rats, pigs, and humans; however, the underlying mechanisms are unclear. We have successfully established two immortalized human granulosa cell lines by SV40 large T antigen transfection. In the process, we have characterized multiple cellular and molecular features of these immortalized cells and compared these characteristics with those of primary cultured granulosa cells. The features examined include the expression patterns of cytoskeletal proteins (vimentin, cytokeratin 5/6 and desmin), adhesion molecules (Connexin 43 and E-cadherin), steroidogenic enzymes (StAR, p450scc and 3β-HSD, steroid receptors (ER-α,-β and PR-α,-β and gonadotropin receptors (LH and FSH), as well as cell morphology, anchorage independent growth, growth potential, and progesterone production. In addition to its well-established actions on the pituitary–gonadal axis, GnRH-I or II suppressed proliferation and directly induced apoptosis in human granulosa cells. The intracellular signals of apoptosis induced by GnRH I or II, in turn, are mediated by activation of the proteolyic caspase cascade, involving caspase 8,3 and 7. In addition, FSH protected human granulosa cells from undergoing apoptosis induced by GnRH I or II. GnRH I or II also significantly attenuated the stimulatory effect of IGF I on granulosa cell proliferation. Correspondingly, IGF I decreased while GnRH I or II increased cleaved caspases 3 in our granulosa cell line; furthermore, IGF I significantly attenuated the expression of cleaved caspase 3 induced by GnRH I or II. These interactions of IGF I and GnRH I or II in regulating granulosa cell proliferation or apoptosis are mediated through Akt in human granulosa cells. In conclusion, we have established two granulosa cell lines and performed integrated investigations of multiple characteristics to elucidate more clearly the characteristicsof human ovarian granulosa cells. Additionally, the present study demonstrated that GnRH I or II mediates antiproliferate effects via stimulation of granulosa cell apoptosis and inhibition of IGF I activities through Akt signaling pathway in human granulosa cells.

Tractability of the Fredholm problem of the second kind

description: We study the tractability of computing ε-approximations of the Fredholm problem of the second kind: given f ∈ Fd and q ∈ Q2d, find u ∈ L2(Id) satisfying u(x)− q(x,y)u(y)dy=f(x) ∀x∈Id =[0,1]d. Id Here, Fd and Q2d are spaces of d-variate right hand functions and 2d-variate kernels that are continuously embedded in L2(Id) and L2(I2d), respectively. We consider the worst case setting, measuring the approximation error for the solution u in the L2 (I d )-sense. We say that a problem is tractable if the minimal number of information operations of f and q needed to obtain an ε- approximation is sub-exponential in ε−1 and d. One information operation corresponds to the evaluation of one linear functional or one function value. The lack of sub-exponential behavior may be defined in various ways, and so we have various kinds of tractability. In particular, the problem is strongly polynomially tractable if the minimal number of information operations is bounded by a polynomial in ε−1 for all d. We show that tractability (of any kind whatsoever) for the Fredholm problem is equivalent to tractability of the L2-approximation problems over the spaces of right-hand sides and kernel functions. So (for example) if both these approximation problems are strongly polynomially tractable, so is the Fredholm problem. In general, the upper bound provided by this proof is essentially non-constructive, since it involves an interpolator algorithm that exactly solves the Fredholm problem (albeit for finite-rank approximations of f and q). However, if linear functionals are permissible and that Fd and Q2d are tensor product spaces, we are able to surmount this obstacle; that is, we provide a fully-constructive algorithm that provides an approximation with nearly-optimal cost, i.e., one whose cost is within a factor ln ε−1 of being optimal.

description: The dynamic response and wake of a circular cylinder undergoing vortex-induced vibrations (VIV) is investigated experimentally using a cyber-physical force-feedback system and particle image velocimetry (PIV) measurements. The effects of the structural mass ratio and mass-damping on the VIV amplitude and frequency response are investigated at a constant Reynolds number by manipulating the structural mass, stiffness and damping in the cyber-physical system. The extent of amplitude modulations in VIV is investigated and a new metric is proposed to quantify the extent of amplitude modulations. A methodology for extracting relevant flow physics associated with coherent structures in the flow is presented for VIV data. Low-order models (LOM) are proposed to describe the dynamics of the wake in each of the VIV branches based on the evolution of the modal temporal coefficients obtained from the proper orthogonal decomposition (POD). The low-order modelling approach is re fined by including a phase-averaging term to better model cases where significant spatial oscillations of the velocity field occur.

description: We consider N=2 Kazama-Suzuki model on CP^N=SU(N+1)/SU(N)xU(1). It is known that the N=2 current algebra for the supersymmetric WZW model, at level k, is a nonlinear algebra. The N=2 W_3 algebra corresponding to N=2 was recovered from the generalized GKO coset construction previously. For N=4, we construct one of the higher spin currents, in N=2 W_5 algebra, with spins (2, 5/2, 5/2, 3). The self-coupling constant in the operator product expansion of this current and itself depends on N as well as k explicitly. We also observe a new higher spin primary current of spins (3, 7/2, 7/2, 4). From the behaviors of N=2, 4 cases, we expect the operator product expansion of the lowest higher spin current and itself in N=2 W_{N+1} algebra. By taking the large (N, k) limit on the various operator product expansions in components, we reproduce, at the linear order, the corresponding operator product expansions in N=2 classical W_{\infty}^{cl}[λ] algebra which is the asymptotic symmetry of the higher spin AdS_3 supergravity found recently.

description: We investigate the empirical content of the Nash solution to two-player bar-gaining games. The bargaining environment is described by a set of variables that may affect agents' preferences over the agreement sharing, the status quo outcome, or both. The outcomes (i.e., whether an agreement is reached, and if so the individual shares) and the environment (including the size of the pie) are known, but neither are the agents' utilities nor their threat points. We consider both a deterministic version of the model in which the econometrician observes the shares as deterministic functions of the variables under consideration, and a stochastic one in which because of latent disturbances only the joint distribution of incomes and outcomes is recorded. We show that in the most general framework any outcome can be rationalized as a Nash solution. However, even mild exclusion restrictions generate strong implications that can be used to test the Nash bargaining assumption. Stronger conditions further allow to recover the underlying structure of the bargaining, and in particular, the cardinal representation of individual preferences in the absence of uncertainty. An implication of this finding is that empirical works entailing Nash bargaining could (and should) use much more general and robust versions than they usually do.
Inward FDI in Norway and its policy context

description: Norwegian inward foreign direct investment (IFDI) has increased rapidly since 2000. A stock of US$ 30 billion in 2000 grew by almost 300% to US$ 116 billion by 2009, a growth stronger than that of most other OECD member countries. The development of Norwegian IFDI has been rather uneven, with stable periods punctuated by boom years. IFDI in 2008 was lower than in 2007, partly reflecting the cooling down of the world economy as a result of the international financial and economic crisis. The latest available data indicate that IFDI remained in a slump in 2009. The composition of Norwegian IFDI largely follows the structure of Norway's private-sector economy, with a clear dominance of the oil and gas sector. The manufacturing sector is gradually losing its appeal to foreign investors, although more slowly than one would expect considering the reduced importance of this sector in the Norwegian economy.

description: This exploratory study examines reproductive rights discourse through qualitative content analysis of social media posts. Twitter is an important avenue in which critical discourse and social movements are formed and sustained. While traditional media has been analyzed for framing the abortion debate in the United States, less is known about the framing used by abortion rights supporters on social media. My convenience, purposive sample consists of Tweets from Planned Parenthood and National Organization of Women, two leading reproductive rights organizations. To incorporate voices traditionally silenced, SisterSong and National Latina Institute for Reproductive Justice Tweets are also included in the sample. By understanding how prominent and intersectional pro-choice organizations engage with their audiences, I uncover themes of support and solidarity against anti-abortion legislation. Thematic analysis reveals five themes of support following the overruling of Roe v. Wade: resilience, action call, identity intersectionality, educational content, and identity oppression. Resilience was the most common theme, demonstrating how resilience is a dynamic, socially constructed process that is essential to building and sustaining engagement in a movement. These findings deepen our understanding of the ways organizations use social media to sustain a social movement and oppose legislation. Online discourse provides a way to discuss abortion and share resources that allow for more diverse voices than traditional media. Social media offers new ways for social movements to unfold and may give a powerful platform for those with less power in traditional media and social systems. This study contributes to the literature of social movements and digital communities and applies a feminist intersectional framework to understand digital activism in the era following the overruling of Roe v. Wade.

description: The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms. In a thermal gas at a temperature of 1000 K, pairs of magnesium atoms, colliding in their electronic ground state, are excited into coherent superpositions of bound rovibrational levels in an electronically excited state. The rovibrational coherence is probed by a time-delayed third photon, resulting in quantum beats in the UV fluorescence. A comprehensive theoretical model based on ab initio calculations rationalizes the generation of coherence by Franck-Condon filtering of collision energies and partial waves, quantifying it in terms of an increase in quantum purity of the thermal ensemble. Our results open the way to coherent control of a binary reaction.
