description: We present an analysis of the long-term optical variability for $\sim50,000$ nearby (z<0.055) galaxies from the NASA-Sloan Atlas, $35,000$ of which are low-mass ($M_{\ast}<10^{10}~M_{\odot}$). We use difference imaging of Palomar Transient Factory (PTF) R-band observations to construct light curves with typical baselines of several years. We then search for subtle variations in the nuclear light output. We determine whether detected variability is AGN-like by assessing the fit quality to a damped random walk model. We identify 424 variability-selected AGN, including 244 with stellar masses between $10^{7}$ and $10^{10}~M_{\odot}$. 75% of low-mass galaxies with AGN-like variability have narrow emission lines dominated by star formation. After controlling for nucleus magnitude, the fraction of variable AGN is constant down to $M_{\ast}=10^{9}~M_{\odot}$, suggesting no drastic decline in the BH occupation fraction down to this stellar mass regime. Combining our NASA-Sloan Atlas sample with samples of nearby galaxies with broad H$α$ emission, we find no dependence of variability properties with black hole mass. However, we caution that the variable AGN fraction is strongly dependent on baseline. For baselines less than two years, the variable fraction for the full sample is 0.25%, compared to 1.0% for baselines longer than two years. Finally, comparing Stripe 82 light curves (Baldassare et al. 2018) to PTF light curves, we find populations of changing-look AGN: 8 galaxies that are variable in Stripe 82, but quiescent in PTF, and 15 galaxies where the reverse is true. Our PTF work demonstrates the promise of long-term optical variability searches in low-mass galaxies for finding AGNs missed by other selection techniques.

description: Energy economy optimization (EEO) models employ formal search techniques to explore the future decision space over several decades in order to deliver policy-relevant insights. EEO models are a critical tool for decision-makers who must make near-term decisions with long-term effects in the face of large future uncertainties. While the number of model-based analyses proliferates, insufficient attention is paid to transparency in model development and application. Given the complex, data-intensive nature of EEO models and the general lack of access to source code and data, many of the assumptions underlying model-based analysis are hidden from external observers. This paper discusses the simplifications and subjective judgments involved in the model building process, which cannot be fully articulated in journal papers, reports, or model documentation. In addition, we argue that for all practical purposes, EEO model-based insights cannot be validated through comparison to real world outcomes. As a result, modelers are left without credible metrics to assess a model's ability to deliver reliable insight. We assert that EEO models should be discoverable through interrogation of publicly available source code and data. In addition, third parties should be able to run a specific model instance in order to independently verify published results. Yet a review of twelve EEO models suggests that in most cases, replication of model results is currently impossible. We provide several recommendations to help develop and sustain a software framework for repeatable model analysis.

 Salmacina chilensis Gallardo, 1969: 9–12, pl. I and II, figs. 1–6. Type locality: 20º48’S, 70º21’W, off Punta Patache, Chile.
 Salmacina chilensis.— Nogueira and ten Hove, 2000: 158–159, tab. 1–2 (discussion of the genus).
 Diagnosis. Tube white, thin. Branchial crown with 9–10 radioles per lobe; radiole tip not inflated. Opercular peduncle or operculum absent. Thorax with seven chaetigers. Collar with fin-and-blade chaetae, with proximal denticulate expansion separate of distal limbate zone (Fig. 10F), with numerous teeth (Fig. 10G). All thoracic chaetigers (except collar segment) with “ Apomatus ” chaetae. Thoracic uncini saw shaped, with eight rows of teeth and two teeth in each row. Abdomen with 36 chaetigers.
 Habitat. Depth: 282 m. On the brachyuran crab Lophorochinia parabranchia.
 Distribution. Only known from northern Chile (Gallardo 1969).
 Taxonomic remarks. According to Nogueira and ten Hove (2000), Salmacina chilensis is very different to any other species of Salmacina, in terms of the large number of radioles present. Moreover, the arrangement of the teeth in the fin-and-blade collar chaetae (Figs 10F–G) “is rather more reminiscent of Protis or Chitinopoma, than of Salmacina ” (Nogueira & ten Hove 2000: 157).

description: We construct a short-range resonating valence-bond state (RVB) on the ruby lattice, using projected entangled-pair states (PEPS) with bond dimension $D=3$. By introducing non-local moves to the dimer patterns on the torus, we distinguish four distinct sectors in the space of dimer coverings, which is a signature of the topological nature of the RVB wave function. Furthermore, by calculating the reduced density matrix of a bipartition of the RVB state on an infinite cylinder and exploring its entanglement entropy, we confirm the topological nature of the RVB wave function by obtaining non-zero topological contribution, $γ=-\rm{ln}\ 2$, consistent with that of a $\mathbb{Z}_2$ topological quantum spin liquid. We also calculate the ground-state energy of the spin-$\frac{1}{2}$ antiferromagnetic Heisenberg model on the ruby lattice and compare it with the RVB energy. Finally, we construct a quantum-dimer model for the ruby lattice and discuss it as a possible parent Hamiltonian for the RVB wave function.

description: This study was designed to report the biological effect of nickel oxide nanoparticles (NiO NPs) in albino mice. Five weeks old albino mice of both sex were intraperitoneally injected either with 20mg (low dose) or 50mg/mL saline/Kg body weight (high dose) of NiO NPs for 14 days. Saline treated controls were maintained in parallel. Complete blood count, selected serum biochemical parameters and oxidative stress biomarkers from vital organs were determined in all subjects. Results: Male mice treated with NiO NPS had increased blood urea nitrogen, elevated superoxide dismutase (SOD) in liver elevated MDA in liver, kidney and heart and reduced catalase activity in heart and kidney. Female mice treated with NiO NPs had significantly reduced serum albumin and total proteins, SOD in lungs and elevated MDA in liver. Discussion: We are reporting that intraperitoneal injections of NiO NPs for 14 days drastically affect blood serum parameters and oxidative stress biomarkers from vital organs of albino mice. Conclusion: Toxic effects of NiO NPs were dose and sex dependent and they were more pronounced at higher dose and in male mice.

description: The next generation of electromagnetic and gravitational wave observatories will open unprecedented windows to the birth of the first supermassive black holes. This has the potential to reveal their origin and growth in the first billion years, as well as the signatures of their formation history in the local Universe. With this in mind, we outline three key focus areas which will shape research in the next decade and beyond: (1) What were the "seeds" of the first quasars; how did some reach a billion solar masses before z$\sim7$? (2) How does black hole growth change over cosmic time, and how did the early growth of black holes shape their host galaxies? What can we learn from intermediate mass black holes (IMBHs) and dwarf galaxies today? (3) Can we unravel the physics of black hole accretion, understanding both inflows and outflows (jets and winds) in the context of the theory of general relativity? Is it valid to use these insights to scale between stellar and supermassive BHs, i.e., is black hole accretion really scale invariant? In the following, we identify opportunities for the Canadian astronomical community to play a leading role in addressing these issues, in particular by leveraging our strong involvement in the Event Horizon Telescope, the {\it James Webb Space Telescope} (JWST), Euclid, the Maunakea Spectroscopic Explorer (MSE), the Thirty Meter Telescope (TMT), the Square Kilometer Array (SKA), the Cosmological Advanced Survey Telescope for Optical and ultraviolet Research (CASTOR), and more. We also discuss synergies with future space-based gravitational wave (LISA) and X-ray (e.g., Athena, Lynx) observatories, as well as the necessity for collaboration with the stellar and galactic evolution communities to build a complete picture of the birth of supermassive black holes, and their growth and their influence over the history of the Universe.

description: Purpose: The present study evaluates the in-vitro anti-tumorigenic potential of leaf methanol extracts of A. muricata (LMAM). Materials and methods: The cytotoxic activity was assessed in MCF-7 cells by MTT assay at various concentrations ranging from 25-250µg/mL. MCF-7 cells were treated with 50 and 100µg/mL LMAM for 24h. To detect LMAM-induced apoptosis; Hoescht 33342 staining along with Cell cycle analysis, Annexin-PI probe as well as oxidative stress damage by reactive oxygen species (ROS) measurements were determined using flow cytometric analysis. While, caspase-3 expression levels were studied employing qRT-PCR method. Results: LMAM exhibited significant inhibition of MCF-7 cells with an IC50 value of 85.55µg/mL. Hoescht staining showed marked morphological features characteristic of apoptosis in LMAM treated cells. Cell cycle analysis confirmed proven capability of LMAM showing 30% rise in G1 phase upon treatment with 100µg/mL LMAM, thus inducing cell cycle arrest at G1 phase and a rise in sub G0-G1 population paralleled with a decrease in S phase. Flow cytometric analysis with Annexin V-FITC-PI staining indicated an increase in the early and late apoptotic population with 3.38% and 19.47% rise respectively when treated with 100µg/mL LMAM. Treatment with 100µg/mL LMAM caused an increase in intracellular ROS with MFI value 3334.08. Upregulation of caspase-3 was observed with a 2.18 and 32.47 fold increase compared to control in MCF-7 cells cultured at 50µg/mL and 100µg/mL LMAM respectively suggesting caspase-dependent apoptosis. Conclusion: LMAM proved as a potent ethno-chemopreventive agent and a potential lead in cancer treatment attributable to the synergistic interactive properties of phytoconstituents.

description: Upper bounds on the energy scale at the end of inflation in the Randall-Sundrum type II braneworld scenario are derived. The analysis is made exact by introducing new parameters that represent extensions of the Hubble flow parameters. Only very weak assumptions about the form of the inflaton potential are made. In the high energy and slow roll regime the bounds depend on the amplitude of gravitational waves produced during inflation and become stronger as this amplitude increases.

title: Epistemologies of possibility: social movements, knowledge production and political transformation
Creators: name: Lamble, Sarah R.
Publisher: name: University of Kent
Year: 2022

description: Urgent global problems - whether military conflicts, economic insecurities, immigration controls or mass incarceration-not only call for new modes of political action but also demand new forms of knowledge. For if knowledge frameworks both shape the horizons of social intelligibility and chart t he realms of political possibility, then epistemological interventions constitute a crucial part of social change. Social movements play a key role in this work by engaging in dissident knowledge practices that open up space for political transformation. But what are the processes and conditions through which social movements generate new ways of knowing?'What is politically at stake in the various knowledge strategies that activists use to generate social change? Despite a growing literature on the role of epistemological dimensions of protest, social movement studies tend to neglect specific questions of epistemological change. Often treating knowledge as a resource or object rather than a power relation and a social practice, social movement scholars tend to focus on content rather than production, frames rather than practices, taxonomies rather than processes. Missing is a more dynamic account of the conditions, means and power relations through which transformative knowledge practices come to be constituted and deployed. Seeking to better understand processes of epistemological transformation, this thesis explores the relationship between social movements, knowledge production and political change. Starting from an assumption that knowledge not only represents the world, but also works to constitute it, this thesis examines the role of social movement knowledge practices in shaping the conditions of political possibility. Drawing from the context of grassroots queer, transgender and feminist organizing around issues of prisons and border controls in North America, the project explores how activists generate new forms of knowledge and forge new spaces of political possibility. Working through a series of concepts-transformation, resistance, experience, co-optation, solidarity and analogy - this thesis explores different ways of understanding processes of epistemological change with in social movement contexts. It considers processes that facilitate or enable epistemological change and those that limit or prohibit such change. Bringing together a range of theoretical perspectives, including feminist, queer, critical race and post-structuralist analyses, and drawing on interviews with grassroots activists, the thesis explores what is politically at stake in the different ways we conceptualise, imagine and engage in processes of epistemological change.

description: Supermassive black holes (SMBHs) are thought to provide energy that prevents catastrophic cooling in the centers of massive galaxies and galaxy clusters. However, it remains unclear how this "feedback" process operates. We use high-resolution optical data to study the kinematics of multi-phase filamentary structures by measuring the velocity structure function (VSF) of the filaments over a wide range of scales in the centers of three nearby galaxy clusters: Perseus, Abell 2597 and Virgo. We find that the motions of the filaments are turbulent in all three clusters studied. There is a clear correlation between features of the VSFs and the sizes of bubbles inflated by SMBH driven jets. Our study demonstrates that SMBHs are the main driver of turbulent gas motions in the centers of galaxy clusters and suggests that this turbulence is an important channel for coupling feedback to the environment. Our measured amplitude of turbulence is in good agreement with Hitomi Doppler line broadening measurement and X-ray surface brightness fluctuation analysis, suggesting that the motion of the cold filaments is well-coupled to that of the hot gas. The smallest scales we probe are comparable to the mean free path in the intracluster medium (ICM). Our direct detection of turbulence on these scales provides the clearest evidence to date that isotropic viscosity is suppressed in the weakly-collisional, magnetized intracluster plasma.

description: Purpose: Gastrointestinal cancers (GICs) account for about a quarter of cancers. Lately, the circulating microRNAs as a non-invasive biomarker for identifying and monitoring diseases have been recognized. Several studies have examined the role of miR-21 in digestive system carcinoma. We conducted a meta-analysis to assess the diagnostic role of miR-21 in GICs. Methods: Seventeen studies involving 1700 individuals were included in this meta-analysis. The pooled sensitivity, specificity, PLR, NLR, DOR, AUC, SROC, and Q* index were calculated based on true-positive, true-negative, false-negative, and false-positive. Moreover, the subgroup analyses have been performed for miR-21 based on sample types (serum/plasma), normalized genes (U6, miR-16, and miR-39), and ethnicity. Results: The pooled sensitivity 0.722 (95% CI: 0.70–0.74), specificity 0.820 (95% CI: 0.801–0.838), PLR 4.375 (95% CI: 3.226–5.933), NLR 0.308 (95% CI: 0.239–0.398), DOR 16.06 (95% CI: 9.732–26.53) as well as AUC 0.86, and Q* index 0.79 represented the high-grade diagnostic precision of miR-21 in identifying GICs (ESCC, GC, CRC, HCC, and PC). Conclusion: This meta-analysis demonstrated that circulating miR-21 levels can be used to monitor the digestive system carcinomas. Therefore, miR-21 can be a useful biomarker of progression and fair diagnosis in GICs patients.

description: The promise of reinforcement learning is to solve complex sequential decision problems autonomously by specifying a high-level reward function only. However, reinforcement learning algorithms struggle when, as is often the case, simple and intuitive rewards provide sparse and deceptive feedback. Avoiding these pitfalls requires thoroughly exploring the environment, but creating algorithms that can do so remains one of the central challenges of the field. We hypothesise that the main impediment to effective exploration originates from algorithms forgetting how to reach previously visited states ("detachment") and from failing to first return to a state before exploring from it ("derailment"). We introduce Go-Explore, a family of algorithms that addresses these two challenges directly through the simple principles of explicitly remembering promising states and first returning to such states before intentionally exploring. Go-Explore solves all heretofore unsolved Atari games and surpasses the state of the art on all hard-exploration games, with orders of magnitude improvements on the grand challenges Montezuma's Revenge and Pitfall. We also demonstrate the practical potential of Go-Explore on a sparse-reward pick-and-place robotics task. Additionally, we show that adding a goal-conditioned policy can further improve Go-Explore's exploration efficiency and enable it to handle stochasticity throughout training. The substantial performance gains from Go-Explore suggest that the simple principles of remembering states, returning to them, and exploring from them are a powerful and general approach to exploration, an insight that may prove critical to the creation of truly intelligent learning agents.

description: The significant increase of periodontitis, chronic kidney disease (CKD), Alzheimer’s disease and cancer can be attributed to an ageing population. Each disease produces a range of biomarkers that can be indicative of disease onset and progression. Biomarkers are defined as cellular (intra/extracellular components and whole cells), biochemical (metabolites, ions and toxins) or molecular (nucleic acids, proteins and lipids) alterations which are measurable in biological media such as human tissues, cells or fluids. An interesting group of biomarkers that merit further investigation are the polyamines. Polyamines are a group of molecules consisting of cadaverine, putrescine, spermine and spermidine and have been implicated in the development of a range of systemic diseases, in part due to their production in periodontitis. Cadaverine and putrescine within the periodontal environment have demonstrated cell signalling interfering abilities, by way of leukocyte migration disruption. The polyamines spermine and spermidine in tumour cells have been shown to inhibit cellular apoptosis, effectively prolonging tumorigenesis and continuation of cancer within the host. Polyamine degradation products such as acrolein have been shown to exacerbate renal damage in CKD patients. Thus, the use of such molecules has merit to be utilized in the early indication of such diseases in patients.

description: The $(3+1)$-dimensional Einstein-Gauss-Bonnet theory of gravity which breaks the Lorentz invariance in a theoretically consistent and observationally viable way has been recently suggested by Aoki, Gorji and Mukohyama [arXiv:2005.03859]. Here we calculate grey-body factor for Dirac, electromagnetic and gravitational fields and estimate the intensity of Hawking radiation and lifetime for asymptotically flat black holes in this theory. Positive coupling constant leads to much smaller evaporation rate and longer life-time of a black hole, while the negative one enhances Hawking radiation. The grey-body factors for electromagnetic and Dirac fields are smaller for larger values of the coupling constant.

description: Smerdalea Fowler
(Figs 1, 2, 6, 9, 12, 17–22)
 Diagnosis. Species of Smerdalea will run to Stegaspidini in the tribal key of Dietrich et al. (2001) but differ from other Stegaspidini in having the pronotum with a pair of suprahumeral horns and a distally enlarged posterior pronotal process bearing three or more spines; the forewing with crossvein m-cu 2 joining M distad of its fork, and the first anal vein contacting the claval suture for a short distance preapically; and the hind tibia with cucullate setal row I well developed.
 Notes. Deitz (1975) placed Smerdalea in Stegaspidinae (as Stegaspinae) based on the acuminate forewing clavus, exposed scutellum, and lack of abdominal punctation. He included it in his tribe Microcentrini based on the presence of dorsal preapical setae on the hind femur and three cucullate setal rows on the hind tibia. Cryan et al. (2003) transferred the genus to Stegaspidini, citing the presence of a single r-m crossvein in the forewing, the absence of an articulated dorsally hooked lateral plate on the male genital capsule, and the results of a morphology-based phylogenetic analysis, which grouped Smerdalea with other members of Stegaspidini. However, placement of the genus within Stegaspidinae depends, at least in part, on interpretation of the position of the distal m-cu crossvein in Smerdalea (i.e., connected to vein M distad of its fork) as a reversal (character 29 state 2 of Cryan et al. 2003) rather than a plesiomorphy shared with non-stegaspidines (character 29 state 0). Also, because the forewing venation and hind tibial chaetotaxy of Smerdalea differ from those of all other Stegaspidini (other genera of the tribe lack cucullate setal row I on the hind tibia and have crossvein m-cu 2 joining M basad of its fork), placement of Smerdalea in this tribe should be considered tenuous at best. Indeed, the most extensive molecular phylogenetic analysis of Membracidae to date (Lin et al. 2004) placed Smerdalea as sister to a clade comprising Stegaspidinae and Centrotinae, suggesting that the genus represents a lineage distinct from Stegaspidinae sensu Cryan et al. (2003). Discovery of the bizarre but apparently related genus, Smergotomia, n. gen., described below, seems to reinforce this interpretation (see notes under Smergotomia).
 Smerdalea was revised by Cryan and Deitz (1995, 1999) who recognized four species. The following key will separate the known species, including a new species described below.

description: No doubt, among the most exciting discoveries of the third millennium thus far are {\bf Oscillations of Massive Neutrinos} and {\bf Dark Energy} that leads to an accelerated expansion of the Universe. Accordingly, Nuclear Physics is presented with two extraordinary challenges: the need for precise (5% or better) prediction of solar neutrino fluxes within the Standard Solar Model, and the need for an accurate (5% or better) understanding of stellar evolution and in particular of Type Ia super nova that are used as cosmological standard candle. In contrast, much confusion is found in the field with contradicting data and strong statements of accuracy that can not be supported by current data. We discuss an experimental program to address these challenges and disagreements.

Palatini approach to Born-Infeld-Einstein theory and a geometric description of electrodynamics

description: The field equations associated with the Born-Infeld-Einstein action are derived using the Palatini variational technique. In this approach the metric and connection are varied independently and the Ricci tensor is generally not symmetric. For sufficiently small curvatures the resulting field equations can be divided into two sets. One set, involving the antisymmetric part of the Ricci tensor $R_{\stackrel{μν}{\vee}}$, consists of the field equation for a massive vector field. The other set consists of the Einstein field equations with an energy momentum tensor for the vector field plus additional corrections. In a vacuum with $R_{\stackrel{μν}{\vee}}=0$ the field equations are shown to be the usual Einstein vacuum equations. This extends the universality of the vacuum Einstein equations, discussed by Ferraris et al. \cite{Fe1,Fe2}, to the Born-Infeld-Einstein action. In the simplest version of the theory there is a single coupling constant and by requiring that the Einstein field equations hold to a good approximation in neutron stars it is shown that mass of the vector field exceeds the lower bound on the mass of the photon. Thus, in this case the vector field cannot represent the electromagnetic field and would describe a new geometrical field. In a more general version in which the symmetric and antisymmetric parts of the Ricci tensor have different coupling constants it is possible to satisfy all of the observational constraints if the antisymmetric coupling is much larger than the symmetric coupling. In this case the antisymmetric part of the Ricci tensor can describe the electromagnetic field, although gauge invariance will be broken.

description: Correlated anion and cation motion can significantly reduce the overall ion conductivity in electrolytes versus the ideal conductivity calculated based on the diffusion constants alone. Using coarse-grained molecular dynamics simulations, we calculate conductivity and the degree of uncorrelated ion motion in salt-doped homopolymers and block copolymers as a function of concentration and interaction strengths. Calculating conductivity from ion mobility under an applied electric field increases accuracy versus the typical use of fluctuation dissipation relationships in equilibrium simulations. In typical electrolytes, correlation in cation-anion motion is often expected to be reduced at low ion concentrations. However, for these polymer electrolytes with strong ion-polymer and ion-ion interactions, we find correlations are increased at lower concentrations when other variables are held constant. We show this phenomenon is related to the slower ion cluster relaxation rate at low concentrations rather than the static spatial state of ion aggregation or the fraction of free ions.
