description: During the past decade, adult literacy in international development has become out of fashion. A marked decline in international interest in promoting adult literacy has followed the disappointing results of the Experimental World Literacy Programme (UNESCO, 1976). Many development planners now question the need for literacy in settings where printed materials are few. Others look with dismay at the seemingly meager accomplishments of traditional literacy projects--high dropout rates, low levels of skill acquisition, and frequent instances of relapsing into illiteracy after training is completed. Lack of interest on the part of technical assistance agencies and among planners and educators has meant three things. First, there has been a failure to examine the nature and consequences of illiteracy in the wake of rapid change in developing countries. Second, there has been a lack of appreciation of the extent to which illteracy is being addressed in development activities in sectors other than education. Finally, planning and carrying out literacy instruction, in general, has neither improved nor adapted itself to changing circumstances. This note considers these issues with respect to the planning of literacy programs in specific situations. The focus is on literacy training for specific needs brought about by rapid change in Third World regions. In such situations, training is planned around activities which do not primarily, or even secondarily, promote adult literacy. Rather, training focuses on content areas related to development which demand specific literacy skills.

description: The chemical freeze-out curve in heavy-ion collisions is investigated in the context of a quantum chromodynamics (QCD) critical point (CP) search at finite baryon densities. Taking the hadron resonance gas picture at face value, chemical freeze-out points at a given baryochemical potential provide a lower bound on the possible temperature of the QCD CP. We first verify that the freeze-out data in heavy-ion collisions are well described by a constant energy per particle curve, $E/N = \rm const$, under strangeness neutrality conditions ($μ_S \neq 0$, $μ_Q \neq 0$). We then evaluate the hypothetical lower bound on the freeze-out curve based on this criterion in the absence of strangeness neutrality ($μ_S = 0$, $μ_Q = 0$) and confront it with recent predictions on the CP location. We find that recent estimates based on Yang-Lee edge singularities from lattice QCD data on coarse lattices ($N_τ = 6$) place the CP significantly below the freeze-out curve, hinting at the importance of performing continuum extrapolation within this method. Predictions based on functional methods and holography place the CP slightly above the freeze-out curve, indicating that the QCD CP may be located very close to the chemical freeze-out in $A$+$A$ collisions at $\sqrt{s_{NN}} = 3.5$-$6$ GeV.

description: We present an error mitigation strategy composed of Echo Verification (EV) and Clifford Data Regression (CDR), the combination of which allows one to learn the effect of the quantum noise channel to extract error mitigated estimates for the expectation value of Pauli observables. We analyse the behaviour of the method under the depolarizing channel and derive an estimator for the depolarization rate in terms of the ancilla purity and postselection probability. We also highlight the sensitivity of this probability to noise, a potential bottleneck for the technique. We subsequently consider a more general noise channel consisting of arbitrary Pauli errors, which reveals a linear relationship between the error rates and the estimation of expectation values, suggesting the learnability of noise in EV by regression techniques. Finally, we present a practical demonstration of Echo Verified Clifford Data Regression (EVCDR) on a superconducting quantum computer and observe accurate results for the time evolution of an Ising model over spin-lattices consisting of up to 35 sites and circuit depths up to 173 entangling layers.

description: Understanding the drivers of the molecular, physiological, social and environmental factor contributing to healthy states and its diversion to a complex disease is a challenge. Availability of healthcare big data provides new opportunity to understand disease trajectories. Converging biomedical, healthcare and wearable data now offers a unique possibility to understand factors driving disease conditions. Mining of large-scale healthcare datasets help us to understand the drivers of disease and would help to prevent illness. Data-driven mining in massive healthcare datasets would also help us to develop new strategies to improve healthcare delivery. At Mount Sinai Health System, we (http://dudleylab.org) are leveraging the continuum of health-system wide biomedical, clinical and operational databases to improve various facets of healthcare delivery. Use-cases from cardiology, reducing readmission rates, and longitudinal data mining will be discussed. I will also discuss our work on developing a unified data model (individualome) and its potential application in real-time healthcare.

description: We use the First Light And Reionisation Epoch Simulations (FLARES) to study the evolution of the rest-frame ultraviolet (UV) and far-infrared (FIR) sizes for a statistical sample of massive ($\gtrsim10^{9}$M$_{\odot}$) high redshift galaxies (z $\in$ [5,10]). Galaxies are post-processed using the SKIRT radiative transfer code, to self-consistently obtain the full spectral energy distribution and surface brightness distribution. We create mock observations of the galaxies for the Near Infrared Camera (NIRCam) to study the rest-frame UV 1500 $\unicode{xC5}$ morphology. We also generate mock rest-frame FIR (50 $μ$m) photometry and mock ALMA (158 $μ$m) (0.01"-0.03" and $\approx$0.3" angular resolution) observations to study the dust-continuum. We find the effect of dust on observed sizes reduces with increasing wavelength from the UV to optical ($\sim$0.6 times the UV at 0.4$μ$m), with no evolution in FIR sizes. Observed sizes vary within 0.4-1.2 times the intrinsic sizes at different signal to noise ratios (SNR = 5-20) across redshifts. The effect of PSF and noise makes bright structures prominent, whereas fainter regions blend with noise, leading to an underestimation (factor of 0.4-0.8) of sizes at SNR=5. At SNR=15-20, the underestimation reduces (factor of 0.6-0.9) at z=5-8 but due to PSF, at z=9-10, bright cores are dominant, resulting in an overestimation (factor of 1.0-1.2). For ALMA, low resolution sizes are effected by noise which acts as extended emission. The size evolution in UV broadly agrees with current observational samples and other simulations. This work is one of the first to analyse the panchromatic sizes of a statistically significant sample of simulated high-redshift galaxies, complementing a growing body of research highlighting the importance of conducting an equivalent comparison between observed galaxies and their simulated counterparts in the early Universe.

Trends in Chinese paper producers and trade
Creators: name: Shi, Qinglong
Publisher: name: The University of British Columbia
Year: 2013

description: The Trends in Chinese paper producers and trade is a comprehensive analysis on the Chinese paper industry developments, and the policy driving them. There will be two primary parts: wood pulps and paper and paperboard. Wood pulps will be divided to mechanical, chemical and dissolving grade pulps. Paper and paperboard will include printing and writing papers, packaging materials, household and sanitary papers. Because of the recent rapid development of China, and improvement in the standard of living in China, Sanitary and household paper offer a huge potential market in China. There are the excessive production of high grades writing and printing paper in China, which forces producers to seek more export opportunities to sell their products. The Chinese market demand in Wrapping and package paperboard changed substantially from 1961 to 2011. As the consumption of packaging paperboard indirectly reflects the levels of social development and economy, during the period where the Chinese GDP per capita will increase from 3,000 USD to 11,000 USD, the average consumption should also increase stably and reach 100kg in 2016, and finally reach 150kg in 2020. Mechanical wood pulp is obtained by grinding or refining residues into fibers, the technology for producing mechanical pulp for printing paper has not changed much since 1980. Most improvements in technology have been in screening operations. Dissolving wood pulp is made from wood of special quality, with more than 95% alpha-cellulose content and the production is limited by the resource. Since cotton farmland has not increased and the production will not change much in the future, choice of raw material is limited to wood and bamboo. China consumes a substantial amount of chemical pulp. Canadian wood pulp has been used for a longest time in China since it has consistent quality while there are some new competitors. Brazil and Chile have been producing kraft pulp at increasing rates with the lowest cost in the world.
Porosity-viscosity relationships during compaction of pumice
Creators: name: Gainer, Daniel
Publisher: name: The University of British Columbia
Year: 2013

description: During compaction of pyroclastic material, strain is mainly accommodated by volume reduction from the closing of pore space. At temperatures above the materials softening point, this deformation is achieved through viscous relaxation. The effective viscosity of the material increases with loss of porosity and increased viscosity can lead to brittle deformation. Here, high temperature experiments are conducted on pumice cores of diameter 4 cm and length 8 cm, sampled from Mount Meager’s Pebble Creek Formation using the Volcanic Deformation Rig in the Centre for Experimental Study of the Lithosphere (CESL) at the University of British Columbia. Cores were deformed at 875 °C under a constant displacement rate of 2.78*10-⁴ or at constant loads of 1334 N and 3559 N. Initial and final porosities were measured for each core. The acoustic emissions of brittle deformation were measured with an Acoustic Emission System (PCI-2 AE) where high acoustics indicated fracturing from brittle deformation. Samples showed a strain dependent rheology where the effective viscosity (ηe) increased with increased strain and reduced porosity until viscous deformation was replaced by viscous and brittle deformation. Results show that at this point of viscous-brittle deformation, the stress required to continue straining the material at the same rate increases exponentially. With a constant applied stress, the strain rate will rapidly decrease across this point. At 875 °C Log10(ηe) increases linearly with porosity loss to a point of zero porosity between 10¹¹˙⁵ to 10¹⁴˙⁵ Pa s. This relationship is important in the welding of ignimbrites and for volcanic recharge, as pyroclastic material can seal a volcanic conduit. The porosity will affect the materials permeability, which will dictate its ability to either effusively release gases or build up pressure leading to an explosive eruption.
Asymptotic methods for confined fluids

description: The thermodynamics and microstructure of confined fluids with small particle number are best described using the canonical ensemble. However, practical calculations can usually only be performed in the grand-canonical ensemble, which can introduce unphysical artifacts. We employ the method of asymptotics to transform grand-canonical observables to the canonical ensemble, where the former can be conveniently obtained using the classical density functional theory of inhomogeneous fluids. By formulating the ensemble transformation as a contour integral in the complex fugacity plane we reveal the influence of the Yang-Lee zeros in determining the form and convergence properties of the asymptotic series. The theory is employed to develop expansions for the canonical partition function and the canonical one-body density. Numerical investigations are then performed using an exactly soluble one-dimensional model system of hard-rods.

description: Why Endless Consumption of Our Finite Planet Will Take Us to Our Cliff of Doom and How We Can Prevent It
 Pundits and apologists of "green capitalism", an oxymoron, are working strenuously to deceive people. They want people to think that technology will solve all the problems associated with climate change and the planetary rift created by the Anthropocene geological epoch. With the full and enthusiastic cooperation of governments around the world, all underlying social structures such as educational systems, mass media, government public messaging, advertising, corporate public relations and many NGOs are conveying the narrative that the technological prowess of twentieth-first century capitalism will solve all the problems of the increasingly catastrophic planetary events. In this way, the messaging continues to be business as usual. People are led to presume that capitalism and its inherent and unsustainable consumer society will continue by making capitalism more efficient, more ecologically and socially responsible and sustainable as if it were already ecologically and socially sustainable to some extent. We just need to transition to new energy sources and become more efficient in resource consumption. Nonetheless, science has demonstrated that a safe and just transition to make the planet sustainable for the future generations of humans and non-humans, without transgressing the nine planetary boundaries, will require a radical structural and tectonic change to downscale our consumption of resources drastically. This inevitably requires the replacement of capitalism with a new eco-humanistic paradigm for the well-being of people and the planet and not the market. However, given that governments are utterly committed to preserving capitalism, only a global eco-social movement of conscientious and concerned individuals can organise to peacefully and democratically save our home, Planet Earth.

description: Designing a freeform surface to reflect or refract light to achieve a target distribution is a challenging inverse problem. In this paper, we propose an end-to-end optimization strategy for an optical surface mesh. Our formulation leverages a novel differentiable rendering model, and is directly driven by the difference between the resulting light distribution and the target distribution. We also enforce geometric constraints related to fabrication requirements, to facilitate CNC milling and polishing of the designed surface. To address the issue of local minima, we formulate a face-based optimal transport problem between the current mesh and the target distribution, which makes effective large changes to the surface shape. The combination of our optimal transport update and rendering-guided optimization produces an optical surface design with a resulting image closely resembling the target, while the geometric constraints in our optimization help to ensure consistency between the rendering model and the final physical results. The effectiveness of our algorithm is demonstrated on a variety of target images using both simulated rendering and physical prototypes.

description: We studied flow organization and heat transfer properties in mixed turbulent convection within Poiseuille-Rayleigh-Bénard channels subjected to temporally modulated sinusoidal wall temperatures. Three-dimensional direct numerical simulations were performed for Rayleigh numbers in the range $10^6 \leq Ra \leq 10^8$, a Prandtl number $Pr = 0.71$ and a bulk Reynolds number $Re_b \approx 5623$. We found that high-frequency wall temperature oscillations had minimal impact on flow structures, while low-frequency oscillations induced adaptive changes, forming stable stratified layers during cooling. Proper orthogonal decomposition (POD) analysis revealed a dominant streamwise unidirectional shear flow mode. Large-scale rolls oriented in the streamwise direction appeared as higher POD modes and were significantly influenced by lower-frequency wall temperature variations. Long-time-averaged statistics showed that the Nusselt number increased with decreasing frequency by up to 96\%, while the friction coefficient varied by less than 15\%. High-frequency modulation predominantly influenced near-wall regions, enhancing convective effects, whereas low frequencies reduced these effects via stable stratified layer formation. Phase-averaged statistics showed that high-frequency modulation resulted in phase-stable streamwise velocity and temperature profiles, while low-frequency modulation caused significant variations due to weakened turbulence. Turbulent kinetic energy (TKE) profiles remained high near the wall during both heating and cooling at high frequency, but decreased during cooling at low frequencies. A TKE budget analysis revealed that during heating, TKE production was dominated by shear near the wall and by buoyancy in the bulk region; while during cooling, the production, distribution and dissipation of TKE were all nearly zero.

Cross-sectional Dependence in Idiosyncratic Volatility

description: This paper introduces an econometric framework for analyzing cross-sectional dependence in the idiosyncratic volatilities of assets using high frequency data. We first consider the estimation of standard measures of dependence in the idiosyncratic volatilities such as covariances and correlations. Naive estimators of these measures are biased due to the use of the error-laden estimates of idiosyncratic volatilities. We provide bias-corrected estimators and the relevant asymptotic theory. Next, we introduce an idiosyncratic volatility factor model, in which we decompose the variation in idiosyncratic volatilities into two parts: the variation related to the systematic factors such as the market volatility, and the residual variation. Again, naive estimators of the decomposition are biased, and we provide bias-corrected estimators. We also provide the asymptotic theory that allows us to test whether the residual (non-systematic) components of the idiosyncratic volatilities exhibit cross-sectional dependence. We apply our methodology to the S&P 100 index constituents, and document strong cross-sectional dependence in their idiosyncratic volatilities. We consider two different sets of idiosyncratic volatility factors, and find that neither can fully account for the cross-sectional dependence in idiosyncratic volatilities. For each model, we map out the network of dependencies in residual (non-systematic) idiosyncratic volatilities across all stocks.

description: Many swimmers, especially small to medium-sized animals, use intermittent locomotion that differs from continuous swimming of large species. This type of locomotion, called burst-and-coast, is often associated with an energetic advantage. In this work, we investigate the intermittent locomotion inspired by fish locomotion but applied to a propeller. The energy consumption of burst-and-coast cycles is measured and compared to the continuous rotation regime. We show that a substantial drag ratio between the active and passive phases of the motion, as observed in fish, is critical for energy savings. Such a contrast can be obtained using a folding propeller that passively opens and closes as the propeller starts and stops rotating. For this reconfigurable propeller, intermittent propulsion is found to be energetically advantageous, saving up to 24% of the energy required to cruise at a given speed. Using an analytical model, we show that intermittent motion is more efficient than continuous motion when the drag reduction in the coast phase exceeds 65%. For fish-like locomotion, this threshold seems to be closer to 30%. A formal analogy allows us to explain the difference between propeller propulsion and fish locomotion.

description: In recent psychophisiological studies natural stimuli like video or images are commonly used. While measuring and analyzing subject's reaction on the presented stimuli it is essential to pay attention to properties of natural images. Textual content in natural scenes can provide important information about enviroment for human subjects. Therefore posteriori or a priori analisys of stimuli can be useful for research purposes.
Recent most popular approaches for text detection on images include low-level feature processing, such as Stroke Width Transform and Optical character recognition, and higher level feature processing using Convolution Neural Networks (CNN). The image is often pre-processed with slicing window technique in order to obtain multiple subregions and pass them through the network. Here we propose a different approach for differentiation between text and non-text images and for text-heavy region detection. This model is implemented with a Convolutional Neural Network, which generates a saliency map based on probability of observing text in an image region. Then the candidate regions can be extracted to perform additional classfication task and text recognition. We evaluate the proposed algorithm on a dataset of natural images in a variety of scenarios. Detection performance is compared to the existing state-of-the-art algorithms.

Geochemical and hydrogeological characterization of the Norman Point/Ford Cove groundwater regime on Hornby Island, British Columbia

Year: 2013

description: The Heron Rocks Camping Co-operative on Hornby Island, British Columbia is experiencing groundwater quality issues related to salinity. Water samples, down-well logs, and water level data were collected to characterize the groundwater regime in the area. Groundwater sampled from HRCC has elevated conductivity values, high sodium concentrations, and a basic pH as a result of the naturally occurring cation exchange reactions in the bedrock. Groundwater geochemical compositions are tied closely with the geology of the bedrock, in that mudstones facilitate cation exchange and sandstones do not. Options for rehabilitation are evaluated as well as seeking alternative water sources. It is suggested that increasing water storage for a pre-existing well as well as rainwater collection be considered as alternative water sources for this property.

Geochemical characterization of rocks and glasses from dykes in selected sites in Kaua’i, Hawai’i : implications on the Loa and Kea trends

description: Petrological and geochemical characterization (major element, trace element and Pb isotopes) is done on 11 rock and 13 glass samples from dykes in selected sites in the island of Kaua’i (4.0-5.1 Ma). Petrography of hand sample and thin section indicate dykes are composed of tholeiitic basalt and picritic basalt. Major element analyses show all dykes are tholeiitic with consistent enrichment in major elements consistent with the mineralogy, with significant overlap in glass and rock composition in each location. Tholeiitic sample signature suggests dyke magma may be from the shield-building stage of Kaua’i. C1 Chondrite-normalized REE plots indicate dykes are consistent with geochemical signature typical of tholeiitic ocean island basalts. Binary trace element plots represent complex melting processes within the Hawaiian mantle plume resulting from partial melting of a depleted peridotite lithology source. Primitive mantle-normalized extended trace element diagram show typical composition of mantle-plume derived ocean island basalt with primitive mantle source, with enrichment in LIL and HFS elements. Pb isotopes composition show relatively low ²⁰⁶Pb/²⁰⁴Pb for a given ²⁰⁸Pb/²⁰⁴Pb and indicate dyke samples plotted on the Loa trend field with significant overlap with Kea trend lavas, and straddles the Loa-Kea trend boundary line. Comparison with Kaua’i rejuvenated lavas indicate dykes have higher concentrations of radiogenic ²⁰⁶Pb/204Pb and ²⁰⁸Pb/²⁰⁴Pb, and there is significant overlap between dykes and shield stage Kaua’i lavas indicating that overall, Kaua’i shield stage lava sampled transitional to Loa trend magmatism.

description: Recently, two models of quantum-corrected Schwarzschild-like black holes were developed within Effective Quantum Gravity, and the spectra of bosonic perturbations have been analyzed in several recent studies. In this work, we investigate the quasinormal modes of a massless Dirac field perturbations around these black holes. By employing the higher-order WKB method and time-domain integration, we achieved consistency between the two approaches within their common range of validity. This concordance enables us to distinguish the two quantum-corrected black hole models from each other and from their Schwarzschild limit through their quasinormal spectra. In addition, we find approximate analytic expressions for quasinormal modes and grey-body factors in the form of expansion beyond the eikonal limit.

On the virialization threshold for halo mass functions

subject: FOS: Physical sciences

description: In a recent study by Euclid collaboration, the halo mass function (HMF) has been fitted with accuracy better than $1\%$ for the $Λ$CDM model. Several parameters were introduced and fitted against N-body simulations, assuming the usual linearly extrapolated matter density contrast at the collapse time, $δ_c$, as a basic threshold for halo formation. As a result, a new function that multiplies $δ_c$ was introduced, producing an effective threshold that varies both with redshift and mass scale. We show that the redshift evolution of this effective threshold is similar to the one of the linear extrapolated matter density contrast at the virialization time, $δ_{\rm v}$. Assuming the Euclid HMF as a fiducial model, we refit the Sheth-Tormen (ST) HMF using $δ_{\rm v}$ as a threshold. This new fit improves the agreement between ST-HMF and the Euclid one with respect to Despali et al. (2016) fit, specially at high masses. Interestingly, the parameters $a$ and $p$ in this refit have values closer to the Press-Schechter limit of the ST-HMF, showing that the use of $δ_{\rm v}$ can provide semi-analytical HMF less dependent on extra parameters. Moreover, we analyze the consistency of the ST-HMF fitted with $δ_{\rm v}$ in smooth dark energy models with time-varying equation of state, finding an overall good agreement with the evolution of halo abundances expected from the linear evolution of perturbations and the Euclid HMF extrapolated to these scenarios. These findings suggest that the use $δ_{\rm v}$ as a basic function to describe the threshold for halo formation can be a good guide when considering extrapolations for models beyond $Λ$CDM, which are typically harder to study in simulations.

description: The evolution of e-health systems, including electronic health records (EHR) and personal health records (PHR), has the potential to revolutionize the healthcare sector. The implementation of computerized record systems holds the promise of saving lives, preventing medication errors, and yielding substantial cost savings, as demonstrated by estimates suggesting 60,000 lives saved, 500,000 medication errors prevented, and $9.7 billion saved annually (Leapfrog, 2004). The World Health Organization defines e-health as the cost-effective and secure utilization of information and communication technologies across health-related fields, encompassing healthcare services, health surveillance, health education, and research.

E-Health encompasses various application domains, including electronic medical records, telemedicine, telecare services, consumer health informatics, and Internet-based technologies. The transformative potential of information technology in reshaping industries and creating value for stakeholders is widely recognized, particularly in information-intensive sectors like airlines, financial services, and retailing.

In the context of healthcare, the growing population and increasing prevalence of diseases have generated vast amounts of data. E-health systems are gaining prominence due to technological advancements, addressing the data management challenges posed by expanding patient populations and healthcare demands. This paper explores the transformative potential of e-health systems, emphasizing their role in enhancing healthcare delivery, data management, and patient outcomes.

description: This paper presents question-answering on dense video events, a novel task that answers and grounds dense-event questions in long videos, thus challenging MLLMs to faithfully comprehend and reason about multiple events over extended periods of time. To facilitate the study, we construct DeVE-QA -- a dataset featuring 78K questions about 26K events on 10.6K long videos. Our benchmarking shows that state-of-the-art MLLMs struggle on DeVE-QA. For improvement, we propose DeVi, a novel training-free MLLM approach that highlights a hierarchical captioning module, a temporal event memory module, and a self-consistency checking module to respectively detect, contextualize and memorize, and ground dense-events in long videos for question answering. Extensive experiments show that DeVi is superior at answering dense-event questions and grounding relevant video moments. Compared with existing MLLMs, it achieves a remarkable increase of 4.8% and 2.1% for G(round)QA accuracy on DeVE-QA~and NExT-GQA, respectively. Our data and code will be released upon acceptance.

description: Anomalous Sound Detection (ASD) has gained significant interest through the application of various Artificial Intelligence (AI) technologies in industrial settings. Though possessing great potential, ASD systems can hardly be readily deployed in real production sites due to the generalization problem, which is primarily caused by the difficulty of data collection and the complexity of environmental factors. This paper introduces a robust ASD model that leverages audio pre-trained models. Specifically, we fine-tune these models using machine operation data, employing SpecAug as a data augmentation strategy. Additionally, we investigate the impact of utilizing Low-Rank Adaptation (LoRA) tuning instead of full fine-tuning to address the problem of limited data for fine-tuning. Our experiments on the DCASE2023 Task 2 dataset establish a new benchmark of 77.75% on the evaluation set, with a significant improvement of 6.48% compared with previous state-of-the-art (SOTA) models, including top-tier traditional convolutional networks and speech pre-trained models, which demonstrates the effectiveness of audio pre-trained models with LoRA tuning. Ablation studies are also conducted to showcase the efficacy of the proposed scheme.

description: The response of driven frustrated media stems from interacting hysteretic elements. We derive explicit mappings from networks of hysteretic springs to their abstract representation as interacting hysterons. These maps reveal how the physical network controls the signs, magnitudes, symmetries, and pair-wise nature of the hysteron interactions. In addition, strong geometric nonlinearities can produce pathways that require excess hysterons or even break hysteron models. Our results pave the way for metamaterials with geometrically controlled interactions, pathways, and functionalities, and highlight fundamental limitations of abstract hysterons in modeling disordered systems.

description: The Compton-thick Active Galactic Nuclei (AGN) arguably constitute the most elusive class of sources as they are absorbed by large column densities above logN_H(cm^-2)=24. These extreme absorptions hamper the detection of the central source even in hard X-ray energies. In this work, we use both SWIFT and NuSTAR observations in order to derive the most accurate yet Compton-thick AGN luminosity function. We, first, compile a sample of candidate Compton-thick AGN (logN_H(cm^-2)= 24-25) detected in the Swift BAT all-sky survey in the 14-195 keV band. We confirm that they are Compton-thick sources by using the follow-up NuSTAR observations already presented in the literature. Our sample is composed of 44 sources, consistent with a column density of logN_H(cm^-2)=24-25 at the 90% confidence level. These have intrinsic luminosities higher than L(10-50 keV) ~ 3x10^41 erg/s and are found up to a redshift of z=0.05 (200 Mpc). We derive the luminosity function of Compton-thick AGN using a Bayesian methodology where both the full column density and the luminosity distributions are taken into account. The faint end of the luminosity function is flat, having a slope of 0.01(+0.51,-0.74), rather arguing against a numerous population of low luminosity Compton-thick AGN. Based on our luminosity function, we estimate that the fraction of Compton-thick AGN relative to the total number of AGN is of the order of 24 (+5,-5) % in agreement with previous estimates in the local Universe based on BAT samples.

description: Nearly thirty years after its inception, the field of DNA-programmed colloidal self-assembly has begun to realize its initial promise. In this review, we summarize recent developments in designing effective interactions and understanding the dynamic self-assembly pathways of DNA-coated nanoparticles and microparticles, as well as how these advances have propelled tremendous progress in crystal engineering. We also highlight exciting new directions showing that new classes of subunits combining nanoparticles with DNA origami can be used to engineer novel multicomponent assemblies, including structures with self-limiting, finite sizes. We conclude by providing an outlook on how recent theoretical advances focusing on the kinetics of self-assembly could usher in new materials-design opportunities, like the possibility of retrieving multiple distinct target structures from a single suspension or accessing new classes of materials that are stabilized by energy dissipation, mimicking self-assembly in living systems.

description: In comparison to simpler data such as chemical formulas and lattice structures, electronic band structure data provide a more fundamental and intuitive insight into superconducting phenomena. In this work, we generate superconductor's lattice structure files optimized for density functional theory (DFT) calculations. Through DFT, we obtain electronic band superconductors, including band structures, density of states (DOS), and Fermi surface data. Additionally, we outline efficient methodologies for acquiring structure data, establish high-throughput DFT computational protocols, and introduce tools for extracting this data from large-scale DFT calculations. As an example, we have curated a dataset containing information on 2474 superconductors along with their experimentally determined superconducting transition temperatures, which is well-suited for machine learning applications. This work also provides guidelines for accessing and utilizing this dataset. Furthermore, we present a neural network model designed for training with this data. All the aforementioned data and code are publicly available at http://www.superband.work.

description: Building on last year's successful launch of the journal, Student Anthropologist continues the tradition of giving students in Anthropology and any students interested in anthropology, the chance to make their voices heard on issues they find pertinent. The journal gives students an opportunity to see their work in print, providing them a chance to see what the world of anthropology is all about once they leave the confines of university. Eight submissions were selected this year, based on the input of five editors. The topics are diverse, covering issues such as consumerism, cultural appropriation, land ownership, and indigenous rights. As with last year, the papers are of cultural anthropology, again due to greater interest in topics in that field.
