description: We consider propagation of surface plasmon polaritons (SPPs) in linear periodic chains (LPCs) of prolate and oblate metallic spheroids. We show that the SPP group velocity can be efficiently controlled by varying the aspect ratio of the spheroids. For sufficiently small aspect ratios, a gap appears in the first Brillouin zone of the chain lattice in which propagating modes do not exist. depending on the SPP polarization, the gap extends to certain intervals of the Bloch wave number q. Thus, for transverse polarization, no propagating SPPs exist with wave numbers q such that q_c^\perp < | q | < π/h, h being the chain period. For longitudinally polarized SPPs, the gap spans the interval |q|

Nicsmirnovius eximius

description: 35. Nicsmirnovius eximius (Kiser, 1948)
Localities and specimens found: 77 – 4♀, 6♀ ov, 4♀ em, 8j; 79 – 1♀, 1♀ ov, 3j.
Distribution and ecology. According to the present views, N. eximius (formerly known as Alona eximia Kiser, 1948) is distributed generally in Southeast Asia and China (Idris 1983; Sanoamuang 1998; Kotov & Sanoamuang 2004a; Van Damme et al. 2003, 2013; Maiphae et al. 2005, 2008; Tanaka & Ohtaka 2010; Korovchinsky 2013; Kotov et al. 2013b; Ji et al. 2015; Sinev 2016; Tiang-nga et al. 2020; Dadykin et al. 2023). At the same time, it is known that the species penetrates north, up to the Trans-Baikal and Primorsky territories of Russian Asia (Korovchinsky et al. 2021b). In Vietnam, this crustacean is common and widespread (Dang & Ho 2001; Dang et al. 2002; Sinev 2011, 2012; Sinev & Korovchinsky 2013; Gusakov et al. 2014; Phan et al. 2015; Sinev et al. 2017).
Nicsmirnovius eximius is considered a bottom-dwelling rheophilic species, preferring the littoral of lotic water bodies (streams, rivers, waterfalls, dams, channels) in zones with moderate current (Van Damme et al. 2003; Sinev 2016; Korovchinsky et al. 2021b). Sometimes it occurs in stagnant basins too: ponds, lakes, reservoirs, rice fields, floodplains, swamps (Idris 1983; Dang & Ho 2001; Kotov & Sanoamuang 2004a; Tanaka & Ohtaka 2010; Tiang-nga et al. 2020; Dadykin et al. 2023). According to Sinev et al. (2017), in rivers and streams the species can be most abundant in thickets of macrophytes and among well-washed rocks, but it is rare in the layer of bottom sediments. We found a population of N. eximius in Vietnam only in one of the forest streams (see Appendix 1).

Macrotarsomys bastardi

description: Macrotarsomys cf. bastardi Milne-Edwards and G. Grandidier, 1898
The Children’s Cave specimens have been attributed to M. cf. bastardi based on the following characters that allow differentiation from M. koopmani:
● Long incisive foramen ending after the prelobe of M1
● m3 elongated and narrow with no median longitudinal crest between the first and the second lobe of m3 (Figure 4) but presence of an oblique crest ending on the lingual side of the molar.
Attributed material: all from the Upper Stratum: 8 maxillaries; 15 mandibular rami; see Appendix.
The specimens of Children’s Cave display the bunodont molar morphology of Macrotarsomys with round alternate cusps connected medially by a longitudinal crest (Figure 4d,e,g–i). Their m3 allows clear differentiation from M. koopmani because there is never any trace of a longitudinal median link connecting the first and the second lobes. They display some variability in size but compared to the three modern species they correspond to the smallest species, M. bastardi. However, the Children’s Cave specimens display a slight size difference to the modern representatives of this species. The fossil specimens of Children’s Cave are clearly smaller than the larger M. cf. petteri of Andrahomana site (Table 2). There is overlap with Monticolomys koopmani which displays small molars (Figure 5). The few Children’s Cave remains attributed to M. cf. bastardi may belong to a yet undescribed subfossil species, but further revisions of the dental morphology of this species are still needed.

description: In an attempt of clarifying the connection between the photospheric abundance anomalies and the stellar rotation as well as of exploring the nature of "normal A" stars, the abundances of seven elements (C, O, Si, Ca, Ti, Fe, and Ba) and the projected rotational velocity for 46 A-type field stars were determined by applying the spectrum-fitting method to the high-dispersion spectral data obtained with BOES at BOAO. We found that the peculiarities (underabundances of C, O, and Ca; an overabundance of Ba) seen in slow rotators efficiently decrease with an increase of rotation, which almost disappear at v_e sin i > 100 km s^-1. This further suggests that stars with sufficiently large rotational velocity may retain the original composition at the surface without being altered. Considering the subsolar tendency (by several tenths dex below) exhibited by the elemental abundances of such rapidly-rotating (supposedly normal) A stars, we suspect that the gas metallicity may have decreased since our Sun was born, contrary to the common picture of galactic chemical evolution.

The central dogma and cosmological horizons

description: The central dogma of black hole physics -- which says that from the outside a black hole can be described in terms of a quantum system with exp$(\text{Area}/4G_N)$ states evolving unitarily -- has recently been supported by computations indicating that the interior of the black hole is encoded in the Hawking radiation of the exterior. In this paper, we probe whether such a dogma for cosmological horizons has any support from similar computations. The fact that the de Sitter bifurcation surface is a minimax surface (instead of a maximin surface) causes problems with this interpretation when trying to import calculations analogous to the AdS case. This suggests anchoring extremal surfaces to the horizon itself, where we formulate a two-sided extremization prescription and find answers consistent with general expectations for a quantum theory of de Sitter space: vanishing total entropy, an entropy of $A/4G_N$ when restricting to a single static patch, an entropy of a subregion of the horizon which grows as the region size grows until an island-like transition at half the horizon size when the entanglement wedge becomes the entire static patch interior, and a de Sitter version of the Hartman-Maldacena transition.

This suggests that isospin considerations may provide insight into this and perhaps other $\Dz$-meson decay. We also discuss the isospin nature of the nonresonant contribution in the decay, which can be further understood by studying the decay D0 --> pi0 pi0 pi0.

description: This paper presents a wide-range routing method for multiple rovers deployed for a lunar polar exploration mission. In the mission scenario considered in this paper, multiple exploration points are divided into several sets of points to be assigned to multiple rovers. Subsequently, routes between the exploration points are generated for each rover. This assignment and routing problems are well known as the multiple Traveling Salesman Problem (mTSP). The scenario aims to minimize two objective functions: the sum and standard deviation of operation time among the multiple rovers. This problem is then subject to the multi-objective mTSP (MOmTSP). Therefore, the proposed method is composed of a three-step procedure for solving the MOmTSP. First, the k-means algorithm divides an exploration area into several regions for the number of rovers. Subsequently, a routing algorithm with the space-filling curve and 2-opt algorithm determines the order of exploration points in each region. A local path planner then generates a feasible path between two exploration points. The simulation results using the proposed method with 80 cases are statistically analyzed. We confirm that the proposed method solves the multiple optimization problems by finding the routes that can equalize the rover's operation time and minimize their deviations.

description: We study the frictional drag in high mobility, strongly interacting GaAs bilayer hole systems in the vicinity of the filling factor $ν=1$ quantum Hall state (QHS), at the same fillings where the bilayer resistivity displays a reentrant insulating phase. Our measurements reveal a very large longitudinal drag resistivity ($ρ^{D}_{xx}$) in this regime, exceeding 15 k$Ω/\Box$ at filling factor $ν=1.15$. $ρ^{D}_{xx}$ shows a weak temperature dependence and appears to saturate at a finite, large value at the lowest temperatures. Our observations are consistent with theoretical models positing a phase separation, e.g. puddles of $ν=1$ QHS embedded in a different state, when the system makes a transition from the coherent $ν=1$ QHS to the weakly coupled $ν=2$ QHS.

Mavis Gallant’s short fiction : history and memory in the light of imagination
Creators: name: Besner, Neil Kalman
Publisher: name: University of British Columbia
Year: 2010

description: Since 1944, Mavis Gallant has published over one hundred short stories. Her position as Canada's foremost expatriate writer is subsumed in her importance as a major short story writer of the postwar era: I claim that her stories enact the distortions of history and memory caused by the social, cultural, and political upheavals of the second world war. Her stories depart from their realist ground to register impressionistically these fissures in time; style and structure teach readers to discern Gallant's theme in the forms of characters' returns to and evasions of the past. As Gallant traces these returns to moments in memory and history, her fiction modulates between apparent documentary realism and transparent impressionism, between scrupulously accurate representation of a historical world and reflexive commentary on memory's processes of invention. The structure of Gallant's fiction formulates characters' returns to missed moments of insight, returns which imply time's fractured progress in their circular eddies between present and past. Studying Gallant's fiction chronologically, I trace in Chapters One through Five the articulation of a broken dialogue between history and memory which begins with characters fleeing from history's reports into memory's fictions. This dialogue develops as postwar history swamps memory, stranding individuals in an attenuated present tense, and it culminates in characters' realization of history's moment as memory's home. In Chapter Five, I examine how these dialogues between memory and history resolve themselves in Gallant's Linnet Muir stories. I show how these lines of development underscore transformations in narrative structure, in point of view, treatment of time, and creation of character, and how the stories' settings evoke an opposition between North American and European visions of history. In Chapter Six, these analyses lead to a concluding study of imagination in Gallant's stories as a light which illuminates the convergence of history with memory, enabling characters to imagine a homecoming in time. Gallant's stories invite readers to consider the ways in which memory's objective portraits and subjective inventions develop into comments on the writer's art of calling the past into being.

description: We study cohomological gauge theories on total spaces of holomorphic line bundles over complex manifolds and obtain their reduction to the base manifold by U(1) equivariant localization of the path integral. We exemplify this general mechanism by proving via exact path integral localization a reduction for local curves conjectured in hep-th/0411280, relevant to the calculation of black hole entropy/Gromov-Witten invariants. Agreement with the four-dimensional gauge theory is recovered by taking into account in the latter non-trivial contributions coming from one-loop fluctuations determinants at the boundary of the total space. We also study a class of abelian gauge theories on Calabi-Yau local surfaces, describing the quantum foam for the A-model, relevant to the calculation of Donaldson-Thomas invariants.

description: In this paper, we present an approach for the learning of a visuomotor system for a robotic rover using reinforcement learning (RL) within a simulation that combines both proprioceptive and exteroceptive information. With a rising interest in private lunar exploration, compact, power-efficient and cost-efficient rover concepts are becoming numerous. Many of these still use LIDARs for obstacle avoidance, however, using a camera could help achieve a more optimal system. Visual data contains structured information that can be used for understanding texture, localization and object recognition. That said, it is hard to use RL with raw high-resolution visual data due to the dimensional size, with over 6 million inputs in an image alone. By preprocessing the images to be segmented and down sampling to reduce size, we are able to achieve stable learning, and to teach a robot to understand footage to avoid obstacles and reach its goals. This method combines exteroceptive data from the camera and the goal location information along with proprioceptive information, such as the robot”s angular rotation. Moreover, whereas most approaches feed the RL output to a motion controller or trajectory generator, our RL agent is able to directly control the actuator outputs of the rover.

description: Genus Microgale Thomas, 1882
Microgale is a diverse and highly speciose genus, currently understood to be represented in Madagascar by 21 species plus one extinct species (Everson et al. 2016; Jenkins 2018; Jenkins et al. 2022) but suspected to include cryptic species that are in the process of investigation (Olson et al. 2004; S.M. Goodman and L.E. Olson, pers. comm.). Most of the subfossil material of Microgale examined by Major was identified only to the generic level; however it is evident from some of his handwritten label names that he potentially recognised two or more different species. The current study confirmed the presence of two species of Microgale, M. cowani and M. pusilla, among the subfossils in the Children’s Cave. Both species are listed as of Least Concern on the IUCN Red List (Stephenson et al. 2016).
Microgale pusilla and M. cowani are distinguished from each other by skull size but also based on dental morphology. The size difference between the two species of Microgale found as subfossils in the Children’s Cave is clearly shown in Table 4 and Figure 9, with M. pusilla being noticeably smaller than M. cowani.
The dentition of M. pusilla is markedly smaller than that of M. cowani. In M. pusilla the talon of the second upper premolar (P3) is absent or reduced to a cingulum and two roots are present, the posterior root being very broad, whereas in M. cowani P3 has three roots and a talon is present. The first lower deciduous premolar (dp2) and adult (p2) in M. pusilla is caniniform with no anterior accessory cusp and a very small posterior accessory cusp and this tooth has a single root; dp2 and p2 of M. cowani have two roots and in p2 the protoconid has an anterior accessory cusp (paraconid) and posterior accessory cusp (hypoconulid). If the teeth are absent, identification may be determined by the corresponding number of root sockets at the P3 or p2 locus.

From the experimental upper limit on the Ξ^- \to pμ^-μ^- decay, we derive the bound < 22 TeV for the effective Majorana mass of the muon neutrino.

Attributed material: Upper Stratum: 134 maxillary fragments, 346 mandibular rami; see Appendix.
No intact maxillae were observed amongst M. cowani; a few specimens exhibit premolar eruption, while one individual shows a mixture of deciduous and erupting teeth. No deciduous teeth are evident in the mandibular rami of M. cowani, but a few specimens show p2 or p 4 in the process of eruption (Stage 2) and several with p3 erupting (Stage 3). Since the anterior region of the mandible is more fragile than the posterior region and the deciduous dentition more readily lost than the permanent dentition, it is difficult to judge what age classes are present in the subfossil sample. Toothwear of the molars is one criterion used as an approximate method for ageing mammals. Four wear classes were established indicating increasing maturity: unworn molars with clearly defined cusps in juveniles and young adults, slightly worn molars in older adults, and worn and very worn molars which indicate old individuals. The results for the mandibular rami of M. cowani showed that the proportions for three of the wear classes are roughly equivalent: 19% with worn or very worn molars, 23% with no wear and with cusp pattern clearly visible, 24% showing wear and the fourth category with a slightly higher proportion, 34%, with moderately well-defined cusps and slight wear.
There is no variation in size of the mandibular ramus between Modern and subfossil specimens of M. cowani (see Figure 10). The few contemporary specimens of M. cowani collected by Major at Antsirabe and Andranobe, from the area near the Children’s Cave, group towards the upper part of the range of the subfossils on ARL but the mid-part of the range on MH (see Figure 10); however, the sample size is too small for this observation to have any significance.

description: In this paper, we calculate the transverse momentum diffusion coefficient kappa_T of heavy quark and gluon penetration length in the deconfinement phase of Sakai-Sugimoto model, which is known as a holographic dual of large N_c QCD. We find that for the heavy quark moving through the thermal plasma with a constant velocity v<1, the transverse momentum diffusion coefficient kappa_T is proportional to lamda*gamma^{1/3}*T^4/T_d, and the gluon penetration length delta x is proportional to E^{2/5}. These results are different from those calculated in N=4 super-Yang-Mills theory, where kappa_T is proportional to lambda*gamma^{1/2}*T^3 and delta x is proportional to E^{1/3}, respectively. In the high energy limit, the difference between the two pairs of results should be evident, so we expect that the future LHC experiments can tell us which model is more closely related to the realistic strongly coupled QCD at finite temperature.

description: The charge of the subgap states in an Andreev quantum dot (AQD; this is a quantum dot inserted into a superconducting loop) is very sensitive to the magnetic flux threading the loop. We study the sensitivity of this device as a function of its parameters for the limit of a large superconducting gap. In our analysis, we account for the effects of a weak Coulomb interaction within the dot. We discuss the suitability of this setup as a device detecting weak magnetic fields.

description: We use spin-transfer-driven ferromagnetic resonance (ST-FMR) to measure the spin-transfer torque vector T in MgO-based magnetic tunnel junctions as a function of the offset angle between the magnetic moments of the electrodes and as a function of bias, V. We explain the conflicting conclusions of two previous experiments by accounting for additional terms that contribute to the ST-FMR signal at large |V|. Including the additional terms gives us improved precision in the determination of T(V), allowing us to distinguish among competing predictions. We determine that the in-plane component of has a weak but non-zero dependence on bias, varying by 30-35% over the bias range where the measurements are accurate, and that the perpendicular component can be large enough to be technologically significant. We also make comparisons to other experimental techniques that have been used to try to measure T(V).

title: The effect of lean or obese mouse adipocyte on the mesenchymal-to-epithelial transition of MDA-MB-231 cells in 3-dimensional culture
Creators: name: Asante, Emmanuel
Publisher: name: Memorial University of Newfoundland

description: Obese breast cancer (BC) patients have at least 30% increased risk of death from BC compared to non-obese BC patients. This is because obesity is associated with larger tumor sizes and increased rates of metastasis. Obese BC patients respond poorly to treatment compared to non-obese patients, especially when diagnosed with the triple negative BC (TNBC) subtype. The reasons behind the poor treatment outcomes associated with obesity are not fully understood. The Christian Laboratory had previously established a novel 3-dimensional co-culture system that permitted the co-culture of adipocytes and TNBC cells in a manner that mimics an in vivo milieu. Using this system, I demonstrated that lean and obese mice white adipose tissue could induce a mesenchymal-to-epithelial-transition (MET)-like effect in TNBC cells, thus furnishing the BC cells with properties that enable them to colonize and establish tumors in secondary organs. I have also shown that pro-MET factors are systemically secreted. Taken together this study suggests that adipose tissue has the potential to promote secondary tumor formation in lean and obese women. Further work is needed to determine if targeting the MET-like effect induced adipose tissue could reduce metastasis.
A study of nutation dampers with application to wind induced oscillations
Creators: name: Welt, François
Publisher: name: University of British Columbia

description: Performance of a set of torus-shaped nutation dampers, suitable for arresting relatively low frequency oscillations, is studied experimentally using a simple test facility. More important parameters affecting the damper performance are established and their influence assessed for a variety of configurations with the aim to arrive at more promising geometries. Results suggest damping characteristics to be particularly sensitive to physical properties of the liquid used, its height in the torus, damper geometry, and dynamical parameters representing amplitude and frequency. Among the configurations studied, dampers with perforated inside tubes, baffles, horizontal layers and floating rectangular pieces of wood in flow showed most favorable performance in terms of energy dissipated per unit volume. Such nutation dampers are likely to be suitable in tackling a variety of vibrational problems of industrial aerodynamics, earthquake engineering and off-shore structures.

description: Prospective economic developments depend on the behavior of consumer spending. A key
question is whether private expenditures recover once social distancing restrictions are lifted
or whether the COVID-19 crisis had a sustained impact on consumer confidence, preferences,
and hence, spending. The elongated and profound experience of the COVID-19 crisis may
durably affect consumer preferences. We conducted a representative consumer survey in five
European countries in summer 2020 after the release of the first wave’s lockdown restrictions.
We document the underlying reasons for households’ reduction in consumption in five key
sectors: tourism, hospitality, services, retail, and public transports. We identify a large
confidence shock in the Southern European countries and a shift in consumer preferences in
the Northern European countries, particularly among high-income earners. We conclude that
the COVID-19 experience has altered consumer behavior and that long-term sectoral
consumption shifts may occur.
title: Exploring APOBEC3 domain structure: impact on recognition of DNA damage
Creators: name: Button, Erynn
Publisher: name: Memorial University of Newfoundland

description: Activation-induced deoxycytidine deaminase (AID) and apolipoprotein B mRNA editing enzyme, catalytic polypeptide 3 (APOBEC3, or A3) enzymes are a family of deoxycytidine (dC) deaminases involved in somatic hypermutation (SHM), antibody class switch recombination, and antiviral responses. These enzymes share similar structural features in their single active deoxycytidine deaminase (CD) domain, but some family members (A3B/DE/F/G) possess an additional second regulatory CD domain also known as an N-terminal domain (Ntd). AID/A3s mutate the genome indiscriminately, and A3A, A3B, and A3H haplotype II have been associated with cancer development. Thus, to date the paradigm has been that AID/A3s are pro-tumour factors because they transform healthy DNA into damaged and mutated DNA. However, I observed that the activity of A3A (single domain) and A3B (double domain) is increased if their substrate DNA contains environmentally damaged nucleotides such as 8-Oxo-2’-deoxyguanosine (8oxoG) directly adjacent to the dC (in the -2 or -1 nucleotide position). When exposed to substrates containing damaged nucleotides in positions further downstream, further upstream, or containing a greater concentration of damaged bases, A3A failed to demonstrate an activity increase relative to undamaged and -1 position 8oxoG control substrates whereas A3B exhibited significantly increased activity for all distally damaged substrates compared to controls. I propose that the regulatory Ntd of A3B is a key structural component that accounts for binding distally damaged DNA substrates. The notion that AID/A3s can target pre-damaged DNA in addition to non-damaged healthy DNA is a novel insight in the field; understanding the basis of this phenomenon from both the substrate sequence and enzyme structure point of view would advance our basic knowledge and permit exploration of targeting AID/A3 enzymes in cancer.
Some Characterizations of Domination

description: We show that a cocycle has a dominated splitting if and only if there is a uniform exponential gap between singular values of its iterates. Then we consider sets $Σ$ in $GL(d,\mathbb{R})$ with the property that any cocycle with values in $Σ$ has a dominated splitting. We characterize these sets in terms of existence of invariant multicones, thus extending a 2-dimensional result by Avila, Bochi, and Yoccoz. We give an example showing how these multicones can fail to have convexity properties.

description: We demonstrate an all-optical switch that operates at ultra-low-light levels and exhibits several features necessary for use in optical switching networks. An input switching beam, wavelength $λ$, with an energy density of $10^{-2}$ photons per optical cross section [$σ=λ^2/(2π)$] changes the orientation of a two-spot pattern generated via parametric instability in warm rubidium vapor. The instability is induced with less than 1 mW of total pump power and generates several $μ$Ws of output light. The switch is cascadable: the device output is capable of driving multiple inputs, and exhibits transistor-like signal-level restoration with both saturated and intermediate response regimes. Additionally, the system requires an input power proportional to the inverse of the response time, which suggests thermal dissipation does not necessarily limit the practicality of optical logic devices.

description: In the dense-neutrino region at 50-400 km above the neutrino sphere in a supernova, neutrino-neutrino interactions cause large flavor transformations. We study when the multi-angle nature of the neutrino trajectories leads to flavor decoherence between different angular modes. We consider a two-flavor mixing scenario between nu_e and another flavor nu_x and assume the usual hierarchy F(nu_e)>F{antinu_e)>F(nu_x)=F(antinu_x) for the number fluxes. We define epsilon=(F(nu_e)-F(antinu_e))/(F(antinu_e)-F(antinu_x)) as a measure for the deleptonization flux which is the one crucial parameter. The transition between the quasi single-angle behavior and multi-angle decoherence is abrupt as a function of epsilon. For typical choices of other parameters, multi-angle decoherence is suppressed for epsilon>0.3, but a much smaller asymmetry suffices if the neutrino mass hierarchy is normal and the mixing angle small. The critical epsilon depends logarithmically on the neutrino luminosity. In a realistic supernova scenario, the deleptonization flux is probably enough to suppress multi-angle decoherence.

description: We present measurements of a transmission-line network, designed for cloaking applications in the microwave region. The network is used for channelling microwave energy through an electrically dense array of metal objects, which is basically impenetrable to the impinging electromagnetic radiation. With the designed transmission-line network the waves emitted by a source placed in an air-filled waveguide, are coupled into the network and guided through the array of metallic objects. Our goal is to illustrate the simple manufacturing, assembly, and the general feasibility of these types of cloaking devices.

description: We investigate the dynamics of the geometric transitions associated to compactified spacetimes. By including the dynamics of gravity we are able to follow the evolution of collapsing cycles as they attempt to undergo a topology changing transition. Rather than achieving this singular geometry we find that one of two scenarios occur, depending on the initial conditions. Either a horizon forms, shielding a curvature singularity, or the cycle re-expands after an initial contraction phase. For the case where a horizon forms we identify the final state with a known analytic black-hole solution. We also show use our results to demonstate a novel compactification mechanism, owing to the asymptotic structure of this black-hole solution.

description: Let || . || be a norm on R^n. Averaging || (\eps_1 x_1, ..., \eps_n x_n) || over all the 2^n choices of \eps = (\eps_1, ..., \eps_n) in {-1, +1}^n, we obtain an expression ||| . ||| which is an unconditional norm on R^n. Bourgain, Lindenstrauss and Milman showed that, for a certain (large) constant η> 1, one may average over (ηn) (random) choices of \eps and obtain a norm that is isomorphic to ||| . |||. We show that this is the case for any η> 1.

description: We present the first results of a MOS campaign to follow up cluster candidates located via weak lensing. Our main goals are to search for spatial concentrations of galaxies that are plausible optical counterparts of the weak lensing signals, and to determine the cluster redshifts from those of member galaxies. Around each of 36 targeted cluster candidates, we obtain 15-32 galaxy redshifts. For 28 of these targets, we confirm a secure cluster identification. This includes three cases where two clusters at different redshifts are projected along the same line-of-sight. In 6 of the 8 unconfirmed targets, we find multiple small galaxy concentrations at different redshifts. In both the remaining two targets, a single small galaxy concentration is found. We evaluate the weak lensing mass of confirmed clusters. For a subsample of our most cleanly measured clusters, we investigate the statistical relation between their weak lensing mass and the velocity dispersion of their member galaxies, comparing our sample with optically and X-ray selected samples from the literature. Our lensing-selected clusters are consistent with sigma_v=sigma_sis, with a similar scatter to the optically and X-ray selected clusters. We thus find no evidence of selection bias compared to these other techniques. We also derive an empirical relation between the cluster mass and the galaxy velocity dispersion, which is in reasonable agreement with the prediction of N-body simulations in the LCDM cosmology.

description: Atrial fibrillation (AF) is one of the most frequent rhythm disturbance encountered in the population in general. Our study aims to evaluate the in-hospital outcomes of TAVR with AF. We used National Inpatient Sample database from 2011 to 2018. Baseline characteristics and in-hospital outcomes were evaluated in TAVR based on AF status or not in both unmatched and propensity-matched cohorts. A total of 215,938 patients underwent TAVR during our study period and out of these AF was encountered in 89,587 (41.5%) patients. AF patients undergoing TAVR had a higher mean age and had an increased burden of key co-morbidities in the unmatched cohort. With propensity matched 1:1 analysis, AF had higher mortality as compared to no-AF group (2.4% vs. 2.1%, p Patients undergoing TAVR with concomitant AF tended to have increased mortality, complications, length, and cost of stay compared to non-AF patients.
