Guard Your Daggers and Traces: Properties of Guarded (Co-)recursion

Year: 2016
Subjects: subject: Logic in Computer Science (cs.LO)

description: Motivated by the recent interest in models of guarded (co-)recursion, we study their equational properties. We formulate axioms for guarded fixpoint operators generalizing the axioms of iteration theories of Bloom and Ésik. Models of these axioms include both standard (e.g., cpo-based) models of iteration theories and models of guarded recursion such as complete metric spaces or the topos of trees studied by Birkedal et al. We show that the standard result on the satisfaction of all Conway axioms by a unique dagger operation generalizes to the guarded setting. We also introduce the notion of guarded trace operator on a category, and we prove that guarded trace and guarded fixpoint operators are in one-to-one correspondence. Our results are intended as first steps leading, hopefully, towards future description of classifying theories for guarded recursion.

description: We investigate anomalies in liquid silica with molecular dynamics simulations and present evidence for a fragile-to-strong transition at around 3100 K-3300 K. To this purpose, we studied the structure and dynamical properties of silica over a wide temperature range, finding four indicators of a fragile-to-strong transition. First, there is a density minimum at around 3000 K and a density maximum at 4700 K. The turning point is at 3400 K. Second, the local structure characterized by the tetrahedral order parameter changes dramatically around 3000 K from a higher-ordered, lower-density phase to a less ordered, higher-density phase. Third, the correlation time τ changes from an Arrhenius behavior below 3300 K to a Vogel-Fulcher-Tammann behavior at higher temperatures. Fourth, the Stokes-Einstein relation holds for temperatures below 3000 K, but is replaced by a fractional relation above this temperature. Furthermore, our data indicate that dynamics become again simple above 5000 K, with Arrhenius behavior and a classical Stokes-Einstein relation.

description: The common raven (Corvus corax; raven) is native to North America and has increased in abundance, especially throughout western North America, during the last century. Human subsidies have facilitated raven dispersal into less suitable habitats and enabled these populations to maintain higher annual survival and reproduction. Concomitantly, overabundant raven populations are impacting other native at-risk species such as the greater sage-grouse (Centrocercus urophasianus) and potentially the Gunnison sage-grouse (C. minimus). Using Breeding Bird Survey data from 1995–2014, we evaluated raven count data to quantitatively describe changes in abundance and expansion into sagebrush (Artemisia spp.) ecosystems, specifically sage-grouse habitat. We focused our analyses on the 7 sage-grouse management zones (MZs) delineated across 11 western U.S. states and 2 Canadian provinces. We assessed the effects of land cover and anthropogenic disturbance on instantaneous growth rate (r) or carrying capacity (K) of ravens. Abundance of ravens in western and southeastern MZs was greater than northeastern MZs within the greater sage-grouse range. While raven abundance was lower in MZ I and II (Alberta, Canada; Dakotas, Montana, and northwestern Colorado, USA; Saskatchewan, Canada; and Wyoming, USA), raven expansion and percent increase were equivalent or greater than all other MZs. High abundance in MZ VII indicated Gunnison sage-grouse have been exposed to increased raven populations for several decades. Areas with greater electric power transmission line density had higher r; higher K was positively related to proportion of urban land cover within 25 km and burned area within 3 km and negatively related to greater distance from landfills and proportion of forest land cover within 15 km. Ravens have capitalized on human subsidies to increase abundance and expand into sagebrush ecosystems that did not historically support high raven populations. As such, managers are now faced with a new dilemma of reducing populations of a native species to benefit other native sagebrush obligate species.

description: We present NuSTAR hard X-ray observations of Sh 2-104, a compact HII region containing several young massive stellar clusters (YMSCs). We have detected distinct hard X-ray sources coincident with localized VERITAS TeV emission recently resolved from the giant gamma-ray complex MGRO J2019+37 in the Cygnus region. Faint, diffuse X-ray emission coincident with the eastern YMSC in Sh2-104 is likely the result of colliding winds of component stars. Just outside the radio shell of Sh 2-104 lies 3XMM J201744.7+365045 and a nearby nebula NuSTAR J201744.3+364812, whose properties are most consistent with extragalactic objects. The combined XMM-Newton and NuSTAR spectrum of 3XMM J201744.7+365045 is well-fit to an absorbed power-law model with NH = (3.1 +/- 1.0)E22 cm^-2 and photon index Gamma = 2.1 +/- 0.1. Based on possible long-term flux variation and the lack of detected pulsations (< 43% modulation), this object is likely a background AGN rather than a Galactic pulsar. The spectrum of the NuSTAR nebula shows evidence of an emission line at E = 5.6 keV suggesting an optically obscured galaxy cluster at z = 0.19 +/- 0.02 (d = 800 Mpc) and Lx = 1.2E44 erg/s. Follow-up Chandra observations of Sh 2-104 will help identify the nature of the X-ray sources and their relation to MGRO J2019+37. We also show that the putative VERITAS gamma-ray excess south of Sh 2-104 is most likely associated with the newly discovered Fermi pulsar PSR J2017+3625 and not the HII region.

These sums relate to the form of the regularised integrals used in loop regularisation. We show all three are true, extend them to more general powers and produce their full asymptotic series. We also extend a classical result to produce an exact formula for the sum in the last.

Generalized Bayes Approach to Inverse Problems with Model Misspecification

Publisher: name: arXiv
Year: 2022
Subjects: subject: Methodology (stat.ME)

description: We propose a general framework for obtaining probabilistic solutions to PDE-based inverse problems. Bayesian methods are attractive for uncertainty quantification but assume knowledge of the likelihood model or data generation process. This assumption is difficult to justify in many inverse problems, where the specification of the data generation process is not obvious. We adopt a Gibbs posterior framework that directly posits a regularized variational problem on the space of probability distributions of the parameter. We propose a novel model comparison framework that evaluates the optimality of a given loss based on its "predictive performance". We provide cross-validation procedures to calibrate the regularization parameter of the variational objective and compare multiple loss functions. Some novel theoretical properties of Gibbs posteriors are also presented. We illustrate the utility of our framework via a simulated example, motivated by dispersion-based wave models used to characterize arterial vessels in ultrasound vibrometry.

description: It is shown that all of the basic properties of the hydrogen atom can be consistently described in terms of classical electrodynamics instead of taking the electron to be a particle; we consider an electrically charged classical wave field, an "electron wave", which is held in a limited region of space by the electrostatic field of the proton. It is shown that quantum mechanics must be considered to be not a theory of particles but a classical field theory in the spirit of classical electrodynamics. In this case, we are not faced with difficulties in interpreting the results of the theory. In the framework of classical electrodynamics, all of the well-known regularities of the spontaneous emission of the hydrogen atom are obtained, which is usually derived in the framework of quantum electrodynamics. It is shown that there are no discrete states and discrete energy levels of the atom: the energy of the atom and its states change continuously. An explanation of the conventional corpuscular-statistical interpretation of atomic phenomena is given. It is shown that this explanation is only a misinterpretation of continuous deterministic processes. In the framework of classical electrodynamics, the nonlinear Schrodinger equation is obtained, which accounts for the inverse action of self-electromagnetic radiation of the electron wave and completely describes the spontaneous emissions of an atom.

description: We analyze the internal kinematics of 26 Planetary Nebulae (PNe) with low metallicity that appear to derive from progenitor stars of the lowest masses, including the halo PN population. Based upon spatially-resolved, long-slit, echelle spectroscopy drawn from the San Pedro Mártir Kinematic Catalogue of PNe (López et al. 2012), we characterize the kinematics of these PNe measuring their global expansion velocities based upon the largest sample used to date for this purpose. We find kinematics that follow the trends observed and predicted in other studies, but also find that most of the PNe studied here tend to have expansion velocities less than 20 km/s in all of the emission lines considered. The low expansion velocities that we observe in this sample of low metallicity planetary nebulae with low mass progenitors are most likely a consequence of a weak central star wind driving the kinematics of the nebular shell. This study complements previous results (Pereyra et al. 2013, and references therein) that link the expansion velocities of the PN shells with the characteristics of the central star.

description: The problem of user scheduling and power allocation in full-duplex (FD) cellular networks is considered, where a FD base station communicates simultaneously with one half-duplex (HD) user on each downlink and uplink channel. First, we propose low complexity user scheduling algorithms aiming at maximizing the sum rate of the considered FD system. Second, we derive the optimal power allocation for the two communication links, which is then exploited to introduce efficient metrics for FD/HD mode switching in the scheduling procedure, in order to further boost the system rate performance. We analyze the average sum rate of the proposed algorithms over Rayleigh fading and provide closed-form expressions. Our representative performance evaluation results for the algorithms with and without optimal power control offer useful insights on the interplay among rate, transmit powers, self-interference (SI) cancellation capability, and available number of users in the system.

Evaluation of an MRI-based screening pathway for prostate cancer
Creators: name: Eldred-Evans, David
Publisher: name: Imperial College London
Year: 2021

description: In recent years there has been a wealth of debate regarding prostate cancer screening, with a concurrent increase in new imaging techniques for prostate cancer diagnosis. Imaging has been the technique of choice in lung and breast cancer screening programmes but has not been explored for prostate cancer screening. Herein, this thesis explores the role of magnetic resonance imaging (MRI) as a new approach to screen for prostate cancer. Following an introduction to the current screening landscape, my thesis focuses on the development and validation of a fast MRI, known as a prostagram, that could serve as a viable image-based screening test. Evaluation of this new technique is performed within a prospective, population-based, blinded, cohort study which was conducted at seven primary care practices and two imaging centres. A diverse array of performance characteristics of fast MRI are compared to PSA. These encompass biopsy rates, cancer detection rates, diagnostic accuracy and patient reported experience measures. The second half of this thesis focuses on further optimising the fast MRI protocol for screening and exploring methods of integrating it into an alternative screening pathway. The outcomes point towards a pathway which combines a low threshold PSA and a fast MRI as yielding a more acceptable balance between benefits and harms. This is followed by the development of a risk tool to address the challenges of equivocal MRI lesions. Overall my thesis provides a balanced evaluation of fast MRI as a new screening test and the final chapter highlights outstanding challenges that must be addressed for fast MRI to progress as a legitimate screening modality. There is a requirement for all new screening tests to be evaluated in robust randomised controlled trials and the thesis concludes by setting out a phased research framework for fast MRI to enable a full evaluation over the next decade.

description: FeSe exhibits a novel ground state in which superconductivity coexists with a nematic order in the absence of any long-range magnetic order. Here we report an angle-resolved photoemission study on the superconducting gap structure in the nematic state of FeSe$_{0.93}$S$_{0.07}$, without the complication caused by Fermi surface reconstruction induced by magnetic order. We found that the superconducting gap shows a pronounced 2-fold anisotropy around the elliptical hole pocket near the Z point of the Brillouin zone, with gap minima at the endpoints of its major axis, while no detectable gap was observed around the zone center and zone corner. The large anisotropy and nodal gap distribution demonstrate the substantial effects of the nematicity on the superconductivity, and thus put strong constraints on the current theories.

Type:— VIETNAM. Khanh Hoa Province: Khanh Vinh District, Khanh Trung Commune, Suoi Ca Village, 300–400 m, 21 May 2007, N.Q. Dung 2005 (holotype: FIPI!, isotype: NY!).
Stems clustered, climbing, to 10 m long, 3 mm diam. with sheaths. Leaf sheaths green with scattered brown tomentum, with few, recurved, black-tipped spines to 2 mm long; ocreas scarcely developed, to 3 mm long; knees present; flagella present, to 55 cm long; petioles 2.5–3 cm long, spiny abaxially as the sheaths; rachis 14–19 cm long, with scattered, solitary or paired spines abaxially; cirri absent; pinnae 2 per side of rachis, the basal ones 11.5–14 cm long, 1.7–2 cm wide at the middle, linear-lanceolate, without bristles on veins or margins, the apical ones joined proximally for ca. one third their length. Staminate inflorescences to 0.4 m long, arching, flagellate, branched to 2 orders, with 3–4 partial inflorescences; prophylls 7–9 cm long; partial inflorescence bracts tubular, briefly splitting at the apices, with scattered, recurved spines; rachillae 3– 11 per partial inflorescence, 0.5–2 cm long; staminate flowers 1.5 mm long (immature); calyx 1 mm long, deeply split; corolla 1 mm long, split almost to the base; pistillate inflorescences to 0.25 m long, arching, not flagellate, branched to 2 orders, with 2 partial inflorescences; rachillae 3–6, to 1 cm long; pistillate flowers and fruits not seen.
Distribution and habitat: — Endemic to southern Vietnam in Khanh Hoa Province, in primary, evergreen forest at 300–400 m elevation.
Local names and uses:— may chi. The stems are used in basketry.
Discussion: — Calamus parvulus (named for its small size) differs from all other Calamus in Vietnam by its extremely slender stems, and leaves with only two pinnae per side of the rachis. It appears most similar to C. tetradactylus Hance (1875: 289) from which it differs in its more slender stems (3 versus 10 mm), scarcely developed ocreas (versus well–developed), fewer pinnae per side of the rachis (2 versus 8–13), and pinnae without bristles (versus bristly along the margins).

description: Space-fractional quantum mechanics (SFQM) is a generalization of the standard quantum mechanics when the Brownian trajectories in Feynman path integrals are replaced by L{é}vy flights. We introduce L{é}vy quasicrystal by discretizing the space-fractional Schr$\ddot{\text{o}}$dinger equation using the Gr$\ddot{\text{u}}$nwald-Letnikov derivatives and adding on-site quasiperiodic potential. The discretized version of the usual Schr$\ddot{\text{o}}$dinger equation maps to the Aubry-Andr{é} Hamiltonian, which supports localization-delocalization transition even in one dimension. We find the similarities between L{é}vy quasicrystal and the Aubry-Andr{é} (AA) model with power-law hopping and show that the L{é}vy quasicrystal supports a delocalization-localization transition as one tunes the quasiperiodic potential strength and shows the coexistence of localized and delocalized states separated by mobility edge. Hence, a possible realization of SFQM in optical experiments should be a new experimental platform to test the predictions of AA models in the presence of power-law hopping.

Theta Functions on Covers of Symplectic Groups

Year: 2016
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: We study the automorphic theta representation $Θ_{2n}^{(r)}$ on the $r$-fold cover of the symplectic group $Sp_{2n}$. This representation is obtained from the residues of Eisenstein series on this group. If $r$ is odd, $n\le r <2n$, then under a natural hypothesis on the theta representations, we show that $Θ_{2n}^{(r)}$ may be used to construct a generic representation $σ_{2n-r+1}^{(2r)}$ on the $2r$-fold cover of $Sp_{2n-r+1}$. Moreover, when $r=n$ the Whittaker functions of this representation attached to factorizable data are factorizable, and the unramified local factors may be computed in terms of $n$-th order Gauss sums. If $n=3$ we prove these results, which in that case pertain to the six-fold cover of $Sp_4$, unconditionally. We expect that in fact the representation constructed here, $σ_{2n-r+1}^{(2r)}$, is precisely $Θ_{2n-r+1}^{(2r)}$; that is, we conjecture relations between theta representations on different covering groups.

description: Shape coexistence in even-even nuclei is observed when the ground state band of a nucleus is accompanied by another K=0 band at similar energy but with radically different structure. We attempt to predict regions of shape coexistence throughout the nuclear chart using the parameter-free proxy-SU(3) symmetry and standard covariant density functional theory. Within the proxy-SU(3) symmetry the interplay of shell model magic numbers, formed by the spin-orbit interaction, and the 3-dimensional isotropic harmonic oscillator magic numbers, leads to the prediction of specific horizontal and vertical stripes on the nuclear chart in which shape coexistence should be possible. Within covariant density functional theory, specific islands on the nuclear chart are found, in which particle-hole excitations leading to shape coexistence are observed. The role played by particle-hole excitations across magic numbers as well as the collapse of magic numbers as deformation sets in is clarified.

description: In non-interacting systems, bands from non-trivial topology emerge strictly at half-filling and exhibit either the quantum anomalous Hall or spin Hall effects. Here we show using determinantal quantum Monte Carlo and an exactly solvable strongly interacting model that these topological states now shift to quarter filling. A topological Mott insulator is the underlying cause. The peak in the spin susceptibility is consistent with a possible ferromagnetic state at $T=0$. The onset of such magnetism would convert the quantum spin Hall to a quantum anomalous Hall effect. While such a symmetry-broken phase typically is accompanied by a gap, we find that the interaction strength must exceed a critical value for this to occur. Hence, we predict that topology can obtain in a gapless phase but only in the presence of interactions in dispersive bands. These results explain the recent quarter-filled quantum anomalous Hall effects seen in moire systems.

A speciebus similibus (Calamus flagellum, C. guruba, C. rhabdocladus, C. rudentum) pinnis 8–9 aggretatis in duo catervas distantes differt.
Type:— VIETNAM. Khanh Hoa Province: Khanh Vinh District, Khanh Trung Commune, Suoi Ca Village, 300–400 m, 21 May 2007, N.Q. Dung 2004 (holotype: FIPI!, isotype: NY!).
Stems clustered, climbing, to 10 m long, 1.8 cm diam. with sheaths. Leaf sheaths closed, green with brown tomentum, densely covered with yellowish spines to 1.5 cm long, those at the sheath apices longer, to 4 cm long, forming rows on either side of sheath apices and petiole bases; ocreas scarcely developed; knees absent; flagella present, to 60 cm long; petioles to 30 cm long, spiny laterally and abaxially as the sheaths; rachis to 42 cm long, with scattered, solitary, recurved spines abaxially; cirri absent; pinnae 8–9 per side of rachis, 29–35 cm long, 2–3 cm wide at the middle, linear–lanceolate, arranged in two distant groups of 5 pinnae distally and 3–4 proximally, scarcely bristly along the margins, the apical pair of pinnae joined distally for one third to one half their length. Staminate inflorescences to 0.7 m long, arching, flagellate, branched to 2 orders, with 4 partial inflorescences; prophylls not seen; partial inflorescence bracts tubular, briefly splitting at the apices, without spines; rachillae 5–6 per partial inflorescence, 2–5 cm long; staminate flowers not seen; pistillate inflorescences not seen; fruits not seen.
Distribution and habitat: —Endemic to southern Vietnam in Khanh Hoa Province in primary, evergreen forest at 300–400 m elevation.
Local names and uses: — may cam. The stems are used in basketry.
Discussion: — Calamus seriatus (named for its rows of spines at sheath apices) appears most similar to that group of species having the leaf sheath spines conspicuously longer at the sheath apices (C. flagellum Griffith ex Martius (1853: 333), C. guruba Buchanan-Hamilton in Martius (1838: 211), C. rhabdocladus Burret (1930: 884) and C. rudentum Loureiro (1790: 209)). It differs from all these in its 8–9 pinnae per side of the rachis arranged in two distant groups with the apical pair joined at their bases, versus 27–65 pinnae per side of the rachis arranged regularly or sometimes irregularly with the apical pair not joined at their bases.

description: In the emerging quantum internet, complex network topology could lead to efficient quantum communication and enhanced robustness against failures. However, there are some concerns about complexity in quantum communication networks, such as potentially limited end-to-end transmission capacity. These challenges call for model systems in which the feasibility and impact of complex network topology on quantum communication protocols can be explored. Here, we present a theoretical model for complex quantum communication networks on a lattice of spins, wherein entangled spin clusters in interacting quantum spin systems serve as communication links between appropriately selected regions of spins. Specifically, we show that ground state Greenberger-Horne-Zeilinger clusters of the two-dimensional random transverse Ising model can be used as communication links between regions of spins, and we show that the resulting quantum networks can have complexity comparable to that of the classical internet. Our work provides an accessible generative model for further studies towards determining the network characteristics of the emerging quantum internet.

description: We introduce GlassMLP, a machine learning framework using physics-inspired structural input to predict the long-time dynamics in deeply supercooled liquids. We apply this deep neural network to atomistic models in 2D and 3D. Its performance is better than the state of the art while being more parsimonious in terms of training data and fitting parameters. GlassMLP quantitatively predicts four-point dynamic correlations and the geometry of dynamic heterogeneity. Transferability across system sizes allows us to efficiently probe the temperature evolution of spatial dynamic correlations, revealing a profound change with temperature in the geometry of rearranging regions.

description: Using covariant density functional theory with the DDME2 functional and labeling single-particle energy orbitals by Nilsson quantum numbers, a search for particle-hole (p-h) excitations connected to the appearance of shape coexistence is performed for Z=38 to 84. Islands of shape coexistence are found near the magic numbers Z=82 and Z=50, restricted in regions around the relevant neutron midshells N=104 and N=66 respectively, in accordance to the well accepted p-h interpretation of shape coexistence in these regions, which we call neutron-induced shape coexistence, since the neutrons act as elevators creating holes in the proton orbitals. Similar but smaller islands of shape coexistence are found near N=90 and N=60, restricted in regions around the relevant proton midshells Z=66 and Z=39 respectively, related to p-h excitations across the 3-dimensional isotropic harmonic oscillator (3D-HO) magic numbers N=112 and N=70, which correspond to the beginning of the participation of the opposite parity orbitals 1i13/2 and 1h11/2 respectively to the onset of deformation. We call this case proton-induced shape coexistence, since the protons act as elevators creating holes in the neutron orbitals, thus offering a possible microscopic mechanism for the appearance of shape coexistence in these regions. In the region around N=40, Z=40, an island is located on which both neutron p-h excitations and proton p-h excitations are present.

description: This body of work is a response to the question of how to adapt as an artist amid ecological crisis and failure. Using a multidisciplinary approach, I explore environmental comics as a concept, practice, and teaching method. Following Scott McCloud and Sean Carelton’s definitions of comics as a medium based in visual relationality, I examine how its rich history of exploring other than human perspectives, nontraditional storytelling methods and populist readership, provide a unique format for this time. The manifestation of this research has included a published essay surveying contemporary works; place-based comic workshops in the model of ecopedagogy and Lynda Barry’s instructional book Making Comics (2019); an online resource center outlining artistic strategies for environmental comics, functioning similarly to Lisa Jevbratt’s student hub for her former Interspecies Collaboration class; and an autobiographical webcomic. Though not offered as a political solution, by placing myself in the role of facilitator, researcher, and artist, I am trying to deepen my engagement and responsibilities to my human and nonhuman communities.
Generalized Centripetal Force Law and Quantization of Motion Constrained on 2D Surfaces

description: For a particle moves on a 2D surface f(x)=0 embedded in 3D Euclidean space, the geometric momentum and potential are simultaneously admissible within the Dirac canonical quantization scheme for constrained motion. In our approach, not the full scheme but the symmetries indicated by classical brackets [x,H]_{D} and [p,H]_{D} in addition to the fundamental ones [x,x]_{D}, [x,p]_{D} and [p,p]_{D} are utilized, where the subscript D stands for the Dirac bracket. The generalized centripetal force law p=[p,H]_{D} for particle on the 2D surface play the key role, and there is no simple relationship between the force on a point of the surface and its curvatures of the point, in sharp contrast to the motion on a curve.

Metastability in the reversible inclusion process

description: We study the condensation regime of the finite reversible inclusion process, i.e., the inclusion process on a finite graph $S$ with an underlying random walk that admits a reversible measure. We assume that the random walk kernel is irreducible and its reversible measure takes maximum value on a subset of vertices $S_\star\subset S$. We consider initial conditions corresponding to a single condensate that is localized on one of those vertices and study the metastable (or tunneling) dynamics. We find that, if the random walk restricted to $S_\star$ is irreducible, then there exists a single time-scale for the condensate motion. In this case we compute this typical time-scale and characterize the law of the (properly rescaled) limiting process. If the restriction of the random walk to $S_\star$ has several connected components, a metastability scenario with multiple time-scales emerges. We prove such a scenario, involving two additional time-scales, in a one-dimensional setting with two metastable states and nearest-neighbor jumps.

Retinal Neurons Card Game!
Creators: name: Findlay, Kellyanne
Publisher: name: National Teaching Repository
Year: 2023
Subjects: Biological psychology not elsewhere classified

description: This card game provides a fun, interactive way to consolidate knowledge of the retinal neurons. The game described is based on the classic “Snap” card game where the aim is to identify matching cards. In this game, matching means identifying two cards that describe the same retinal neuron. For example, a picture of a rod photoreceptor on one card and a description matching a rod photoreceptor on another card. However, the cards could also be used for a different game such as building a retina. Groups of players could compete (by correctly answering questions, for example) to collect cards representing each retinal neuron to complete the game.
 What is included? Included in this resource are: “Retinal Neurons Card Game”: this document contains the cards required for the game and should be printed double sided, `flip on long edge’. Individual cards can then be laminated and cut out. “Overview of cards”: this spreadsheet shows the information presented on each card. “Retinal Neurons Card Game instructions”: this instruction sheet contains more detailed information about game play. Who can play? Number of players: 2-4 players + 1 additional person to check responses are correct (the `judge’). Given that this information may be new to players, it is prudent to have an independent person there who can check that the responses (match or no match) are correct.
 Cards  The retinal neurons card game includes: 14 rod photoreceptor cards 14 cone photoreceptor cards 6 bipolar cell cards 10 retinal ganglion cell cards 2 `blind spot’ cards* 2 `3-dimensional perception’ cards* *The `blind spot’ cards and the `3-dimensional perception’ cards are optional (more information in the `Retinal Neurons Card Game instructions’ document).

description: Manipulating bosonic condensates with electric fields is very challenging as the electric fields do not directly interact with the neutral particles of the condensate. Here we demonstrate a simple electric method to tune the vorticity of exciton polariton condensates in a strong coupling liquid crystal (LC) microcavity with CsPbBr$_3$ microplates as active material at room temperature. In such a microcavity, the LC molecular director can be electrically modulated giving control over the polariton condensation in different modes. For isotropic non-resonant optical pumping we demonstrate the spontaneous formation of vortices with topological charges of +1, +2, -2, and -1. The topological vortex charge is controlled by a voltage in the range of 1 to 10 V applied to the microcavity sample. This control is achieved by the interplay of a built-in potential gradient, the anisotropy of the optically active perovskite microplates, and the electrically controllable LC molecular director in our system with intentionally broken rotational symmetry. Besides the fundamental interest in the achieved electric polariton vortex control at room temperature, our work paves the way to micron-sized emitters with electric control over the emitted light's phase profile and quantized orbital angular momentum for information processing and integration into photonic circuits.
Highly connected neurons spike less frequently in balanced networks

description: Many biological neuronal networks exhibit highly variable spiking activity. Balanced networks offer a parsimonious model of this variability. In balanced networks, strong excitatory synaptic inputs are canceled by strong inhibitory inputs on average and spiking activity is driven by transient breaks in this balance. Most previous studies of balanced networks assume a homogeneous or distance-dependent connectivity structure, but connectivity in biological cortical networks is more intricate. We use a heterogeneous mean-field theory of balanced networks to show that heterogeneous in-degrees can break balance, but balance can be restored by heterogeneous out-degrees that are correlated with in-degrees. In all examples considered, we find that highly connected neurons spike less frequently, consistent with recent experimental observations.

description: The writing presented in this paper attempts to break down the broad structures within which I exist. I would like to preface the document by stating that I see the writing and art presented in this paper as steps in a broader effort to gain agency and dignity for my community in South Africa and comrades around the world. I hope to examine the complexities of oppression experienced by and perpetuated within subaltern communities. It is imperative that we orient such discussions away from symptomatic issues such as race relations and reductive identity politics, focusing instead on deeper systemic problems such as class disparity and the lasting effects of our colonial past. I wish to first establish a foundational understanding of the violence experienced by colonised peoples and explore the means by which the global South has resisted coloniality and subjugation. It is my duty to honour my heritage and culture in my work and to refocus the discourse of art and culture born under these oppressive structures to reflect value systems that lead to a culture of protest and resistance. To evidence my work with cultures and cultural products without first recognising their rejection from these oppressive institutions would not allow for an honest understanding of their context and value and would only further their consumption as inferior entities. I aim to celebrate my culture outside the purview of the western institution and to utilise cultural resistance to said systems as the underpinnings of my own production. As Paulo Freire models, the fight for freedom as pursued by the oppressed is in part to save the oppressor who can no longer save themselves (Freire 18). Such efforts, though limited by their context, may present a starting point for honest discourse and potential internal shifts both systemically and individually. I thank you for giving me your time and recognise our interaction here as praxis, latent with the potential for change.
