Not just a game : sexual toxicity in online gaming hurts women
Creators: name: Fredman, Leah Ariela

Toxicity
Sexual harassment

description: It is unclear how sexual toxicity in gaming (STIG) affects women psychologically, if it prompts them to withdraw from gaming, or why it might do so. Three preliminary studies established that STIG is especially devastating to women. Preliminary Study 1 demonstrated that relative to men, women viewed STIG to be more serious and upsetting, and were more negatively impacted by STIG than non-sexual toxicity. Preliminary Study 2 found that reports of past STIG, but not past general toxicity, interacted with gender to predict posttraumatic stress disorder (PTSD) checklist scores in women. Furthermore, STIG uniquely predicted reporting past self-verification failure and perceived betrayal, which, in turn, mediated STIG’s effect on PTSD checklist scores. Preliminary Study 3 provided evidence that STIG impacted a new outcome variable, withdrawal from gaming. Specifically, in a sample of female gamers, reports of past STIG experiences predicted past long-term, but not short-term (e.g. quitting mid-match) withdrawal. Also, reports of past general toxicity did not predict either type of withdrawal. Study 1 replicated the findings from Preliminary Studies 2 and 3. Study 1 indicated that toxicity type interacted with gender, such that only women withdrew in the long-term from gaming following STIG (neither gender withdrew in the short-term). Additionally, Study 1 revealed that a feeling of betrayal mediated these effects. To determine the causal impact of the apparent mediators of STIG, Study 2 experimentally manipulated three potential mediators: perceptions of betrayal, self-verification, and control. Females who perceived increased feelings of self-verification from other teammates were less likely to withdraw from gaming; the other two potential mediators trended in the predicted direction but were not significant. Study 3 further validated these ideas with a qualitative study of five female gamers. The participants all believed that STIG’s effects were more serious than general toxicity, and described how combinations of betrayal and lack of self-verification exacerbated their experiences, and eventually led them to withdraw from certain games. The participants also all opined that they believed the onus to combat toxicity more effectively is on the companies, and that it is especially important to focus on combating sexual toxicity.

description: Chain molecules play a key role in the polymer field and in living cells. Our focus is on a new homopolymer model of a linear chain molecule subject to an attractive self-interaction promoting compactness. We analyze the model using simple analytic arguments complemented by extensive computer simulations. We find several striking results: there is a first order transition from a high temperature random coil phase to a highly unusual low temperature phase; the modular ground states exhibit significant degeneracy; the ground state structures exhibit spontaneous dimensional reduction and have a two-layer structure; and the ground states are assembled from secondary motifs of helices and strands connected by tight loops. We discuss the similarities and notable differences between the ground state structures (we call these PoSSuM -- Planar Structures with Secondary Motifs) in the novel phase and protein native state structures.

description: Unparticles ($\U$) interact weakly with particles. The direct signature of unparticles will be in the form of missing energy. We study constraints on unparticle interactions using totally invisible decay modes of $Z$, vector quarkonia $V$ and neutrinos. The constraints on the unparticle interaction scale $Λ_\U$ are very sensitive to the dimension $d_\U$ of the unparticles. From invisible $Z$ and $V$ decays, we find that with $d_\U$ close to 1 for vector $\U$, the unparticle scale $Λ_\U$ can be more than $10^4$ TeV, and for $d_\U$ around 2, the scale can be lower than one TeV. From invisible neutrino decays, we find that if $d_\U$ is close to 3/2, the scale can be more than the Planck mass, but with $d_\U$ around 2 the scale can be as low as a few hundred GeV. We also study the possibility of using $V (Z)\to γ+ \U$ to constrain unparticle interactions, and find that present data give weak constraints.

description: The architecture of circuital quantum computers requires computing layers devoted to compiling high-level quantum algorithms into lower-level circuits of quantum gates. The general problem of quantum compiling is to approximate any unitary transformation that describes the quantum computation, as a sequence of elements selected from a finite base of universal quantum gates. The existence of an approximating sequence of one qubit quantum gates is guaranteed by the Solovay-Kitaev theorem, which implies sub-optimal algorithms to establish it explicitly. Since a unitary transformation may require significantly different gate sequences, depending on the base considered, such a problem is of great complexity and does not admit an efficient approximating algorithm. Therefore, traditional approaches are time-consuming tasks, unsuitable to be employed during quantum computation. We exploit the deep reinforcement learning method as an alternative strategy, which has a significantly different trade-off between search time and exploitation time. Deep reinforcement learning allows creating single-qubit operations in real time, after an arbitrary long training period during which a strategy for creating sequences to approximate unitary operators is built. The deep reinforcement learning based compiling method allows for fast computation times, which could in principle be exploited for real-time quantum compiling.

A Universality in PP-Waves

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We discuss a universality property of any covariant field theory in space-time expanded around pp-wave backgrounds. According to this property the space-time lagrangian density evaluated on a restricted set of field configurations, called universal sector, turns out to be same around all the pp-waves, even off-shell, with same transverse space and same profiles for the background scalars. In this paper we restrict our discussion to tensorial fields only. In the context of bosonic string theory we consider on-shell pp-waves and argue that universality requires the existence of a universal sector of world-sheet operators whose correlation functions are insensitive to the pp-wave nature of the metric and the background gauge flux. Such results can also be reproduced using the world-sheet conformal field theory. We also study such pp-waves in non-polynomial closed string field theory (CSFT). In particular, we argue that for an off-shell pp-wave ansatz with flat transverse space and dilaton independent of transverse coordinates the field redefinition relating the low energy effective field theory and CSFT with all the massive modes integrated out is at most quadratic in fields. Because of this simplification it is expected that the off-shell pp-waves can be identified on the two sides. Furthermore, given the massless pp-wave field configurations, an iterative method for computing the higher massive modes using the CSFT equations of motion has been discussed. All our bosonic string theory analyses can be generalised to the common Neveu-Schwarz sector of superstrings.

description: The recombination history of the Universe depends exponentially on the temperature, T_0, of the cosmic microwave background. Therefore tiny changes of T_0 are expected to lead to significant changes in the free electron fraction. Here we show that even the current 1sigma-uncertainty in the value of T_0 results in more than half a percent ambiguity in the ionization history, and more than 0.1% uncertainty in the TT and EE power spectra at small angular scales. We discuss how the value of T_0 affects the highly redshifted cosmological hydrogen recombination spectrum and demonstrate that T_0 could, in principle, be measured by looking at the low frequency distortions of the cosmic microwave background spectrum. For this no absolute measurements are necessary, but sensitivities on the level of ~30nK are required to extract the quasi-periodic frequency-dependent signal with typical Delta nu/nu~0.1 coming from cosmological recombination. We also briefly mention the possibility of obtaining additional information on the specific entropy of the Universe, and other cosmological parameters.

description: We give a quantitative analysis of clustering in a stochastic model of one-dimensional gas. At time zero, the gas consists of $n$ identical particles that are randomly distributed on the real line and have zero initial speeds. Particles begin to move under the forces of mutual attraction. When particles collide, they stick together forming a new particle, called cluster, whose mass and speed are defined by the laws of conservation. We are interested in the asymptotic behavior of $K_n(t)$ as $n\to \infty$, where $K_n(t)$ denotes the number of clusters at time $t$ in the system with $n$ initial particles. Our main result is a functional limit theorem for $K_n(t)$. Its proof is based on the discovered localization property of the aggregation process, which states that the behavior of each particle is essentially defined by the motion of neighbor particles.

description: Positron Emission Particle Tracking (PEPT) is an imaging method that tracks individual radioactive particles. PEPT relies on the detection of back-to-back photon pairs emitted by positron annihilation. It requires an algorithm to locate the radioactive particles based on the set of lines defined by successive photon-pair detections. We propose and test a new algorithm for this task. The algorithm relies on the maximization of a likelihood arising from a simple Gaussian-mixture model defined in the space of lines. The model includes a component that accounts for spurious lines caused by scattering and random coincidence, and treats the relative activity of particles as well as their positions as parameters to be inferred. Values of these parameters that approximately maximize the likelihood are computed by application of an expectation-maximization algorithm. A generalization of the model that includes the particle velocities and accelerations as additional parameters takes advantage of the information contained in the exact timing of positron annihilations to reconstruct pieces of trajectories rather than fixed positions, with clear benefits. We test the algorithm on both simulated and experimental data. The results show the algorithm to be highly effective for the simultaneous tracking of many particles (up to 80 in one test). It provides estimates of particle positions that are easily mapped to entire trajectories and handles a variable number of particles in the field of view. The ability to track a large number of particles robustly offers the possibility of a dramatic expansion of the scope of PEPT

description: We introduce and study a new optimization problem called Hyper Vertex Cover. This problem is a generalization of the standard vertex cover to hypergraphs: one seeks a configuration of particles with minimal density such that every hyperedge of the hypergraph contains at least one particle. It can also be used in important practical tasks, such as the Group Testing procedures where one wants to detect defective items in a large group by pool testing. Using a Statistical Mechanics approach based on the cavity method, we study the phase diagram of the HVC problem, in the case of random regualr hypergraphs. Depending on the values of the variables and tests degrees different situations can occur: The HVC problem can be either in a replica symmetric phase, or in a one-step replica symmetry breaking one. In these two cases, we give explicit results on the minimal density of particles, and the structure of the phase space. These problems are thus in some sense simpler than the original vertex cover problem, where the need for a full replica symmetry breaking has prevented the derivation of exact results so far. Finally, we show that decimation procedures based on the belief propagation and the survey propagation algorithms provide very efficient strategies to solve large individual instances of the hyper vertex cover problem.

This panel discusses recent and exciting ideas on how to exploit data and leverage machine learning to aid computationally challenging grid operation tasks. Advances in numerical optimization and commercial solvers have allowed distribution grid operators to handle a fairly broad class of operations. However, the rampant integration of renewables call for the need to solve optimal power flow (OPF), battery placement and sizing, and stable control or adaptive protection setting tasks at increasingly faster timescales and over uncertain input parameters. When complexity can hinder real-time operation, learning from big data can be a viable alternative or at least aid in creative ways to accelerate conventional alternatives. In particular, renewable generation and demand together with their OPF decisions can be used to train neural networks to expedite algorithms. Moreover, novel methods from reinforcement learning can promptly optimize inverter settings under the network-constrained and multi-agent setting found in distribution grid operation. Challenging chance-constrained OPF formulations can be dealt with DNN-based approaches to design optimal inverter control policies. Adaptive protection schemes are designed by genuine approaches from innovations learning.

Regulation of the steady-state levels of B800-850 complexes in Rhodobacter capsulatus by light and oxygen
Creators: name: Zucconi, Anthony
Publisher: name: University of British Columbia
Year: 2010

description: Photosynthetic organisms exhibit a variety of responses to changes in light intensity, including differential biosynthesis of chlorophyll-protein complexes. Cultures of Rhodobacter capsulatus grown anaerobically with a low intensity of light (2 W/m²) contained about four times as much B800-850 light harvesting complex as cells grown under high light intensity (140 W/m²). The mRNA transcripts encoding B800-850 beta and alpha peptides were analyzed by Northern blot, S1 nuclease protection and capping with guanylyl transferase. It was found that the steady-state levels of B800-850 mRNAs in high light-grown cultures was about four times as great as in cells grown under low light intensity. Therefore the lesser amounts of mature B800-850 peptide gene products found in cells grown with high light intensity were the result of a posttranscriptional regulatory process. It was also found that there were two polycistronic messages encoding the B800-850 peptides. These messages shared a common 3' terminus but differed in their 5' end segments as a result of transcription initiation at two discrete sites. Moreover the half life of B800-850 mRNAs was about 10 minutes in cells grown with high light and approximately 19 minutes in low light-grown cultures. Transcriptional and translational fusions were constructed between the B800-850 transcription initiation region (from this point on referred to as the puc transcription initiation region; see Fig. 1) and the Escherichia coli lacZ gene. From these studies it was concluded that the rates of transcription initiation of the puc (B800-850) genes was higher in cells grown with high light illumination than in low light-grown cultures, and that the relative amount of B800-850 complexes under these conditions was controlled by a translational or a posttranslational mechanism. The translational and transcriptional fusions were also used for examination of oxygen regulated expression of the puc genes.

Phylogenetic analysis of the genus Megalobatrachonema Yamaguti, 1941 (Ascaridida:Cosmocercoidea:Kathlaniidae) with field and laboratory observations of M. Waldeni

description: The genus Megalobatrachonema (Family Kathlaniidae; Order Ascaridida) was investigated using phylogenetic analysis. A single cladogram was produced with a consistency index of 92.6%. Six species were found valid, two of which are new. Division of the genus into subgenera Megalobatrachonema and Chabaudqolvania was not supported by the phylogenetic hypothesis. Comparison of host and parasite phylogenies suggest that at least two instances of host switching have occurred. Biogeographical analysis of parasites and hosts indicated that vicariance, rather than dispersal, best explains distribution of five of the six. Field and laboratory observations on one of the more evolved species of the genus, M. waldeni, suggests that there is probably a single generation a year, and that transmission to the definitive host occurs in spring and early summer.

description: To investigate the growth history of galaxies, we measure the rest-frame radio, ultraviolet (UV), and optical sizes of 98 radio-selected, star-forming galaxies (SFGs) distributed over $0.3 \lesssim z \lesssim 3$ and median stellar mass of $\log(M_\star/ \rm M_\odot)\approx10.4$. We compare the size of galaxy stellar disks, traced by rest-frame optical emission, relative to the overall extent of star formation activity that is traced by radio continuum emission. Galaxies in our sample are identified in three Hubble Frontier Fields: MACSJ0416.1$-$2403, MACSJ0717.5+3745, and MACSJ1149.5+2223. Radio continuum sizes are derived from 3 GHz and 6 GHz radio images ($\lesssim 0$''$.6$ resolution, $\approx0.9\, \rm μJy\, beam^{-1}$ noise level) from the Karl G. Jansky Very Large Array. Rest-frame UV and optical sizes are derived using observations from the Hubble Space Telescope and the ACS and WFC3 instruments. We find no clear dependence between the 3 GHz radio size and stellar mass of SFGs, which contrasts with the positive correlation between the UV/optical size and stellar mass of galaxies. Focusing on SFGs with $\log(M_\star/\rm M_\odot)>10$, we find that the radio/UV/optical emission tends to be more compact in galaxies with high star-formation rates ($\rm SFR\gtrsim 100\,M_\odot\,yr^{-1}$), suggesting that a central, compact starburst (and/or an Active Galactic Nucleus) resides in the most luminous galaxies of our sample. We also find that the physical radio/UV/optical size of radio-selected SFGs with $\log(M_\star/\rm M_\odot)>10$ increases by a factor of $1.5-2$ from $z\approx 3$ to $z\approx0.3$, yet the radio emission remains two-to-three times more compact than that from the UV/optical. These findings indicate that these massive, {radio-selected} SFGs at $0.3 \lesssim z \lesssim 3$ tend to harbor centrally enhanced star formation activity relative to their outer-disks.

description: Dynamical coupling between matter and gauge fields underlies the emergence of many exotic particle-like excitations in condensed matter and high energy physics. An important stepping stone to simulate this physics in atomic quantum gases relies on the synthesis of density-dependent gauge fields. Here we demonstrate deterministic formation of domain walls in a stable Bose-Einstein condensate with a synthetic gauge field that depends on the atomic density. The gauge field is created by simultaneous modulations of the optical lattice potential and interatomic interactions, and results in domains of atoms condensed into two different momenta. Modeling the domain walls as elementary excitations, we find that the domain walls respond to synthetic electric field with a charge-to-mass ratio larger than and opposite to that of the bare atoms. Our work offers promising prospects to simulate the dynamics and interactions of novel excitations in quantum systems with dynamical gauge fields.

Publisher: name: IEEE
Year: 2023

Transmission expansion planning approaches are evolving as power system operation become more uncertain and volatile, due to factors including increased frequency of extreme natural events, deployment of distributed energy resources and electric transportation and scaling-up of variable renewables. Transmission planners are responding by more accurately modeling the impacts of these phenomena on load, generation, and equipment availability. They are also quickly incorporating novel solutions to deal with the variability of operating conditions (e.g., Special Protection Schemes or series compensation equipment) as candidates for planning efforts. The session will convene planners active in North America, Europe and Latin America to discuss how they are adapting their methodologies and procedures, and the resulting outcomes.

- Grid enhancing technologies in long-term transmission planning (23PESGM4184)
- Probabilistic planning approaches for transmission system reliability and resilience (23PESGM4185)
- Decoupling Baltic States from Russian power system and synchronization with European network (23PESGM4186)
- Innovative transmission planning with co-simulation for high penetration of variable renewable energy (23PESGM4189)

description: This paper introduces a novel geometric multigrid solver for unstructured curved surfaces. Multigrid methods are highly efficient iterative methods for solving systems of linear equations. Despite the success in solving problems defined on structured domains, generalizing multigrid to unstructured curved domains remains a challenging problem. The critical missing ingredient is a prolongation operator to transfer functions across different multigrid levels. We propose a novel method for computing the prolongation for triangulated surfaces based on intrinsic geometry, enabling an efficient geometric multigrid solver for curved surfaces. Our surface multigrid solver achieves better convergence than existing multigrid methods. Compared to direct solvers, our solver is orders of magnitude faster. We evaluate our method on many geometry processing applications and a wide variety of complex shapes with and without boundaries. By simply replacing the direct solver, we upgrade existing algorithms to interactive frame rates, and shift the computational bottleneck away from solving linear systems.
