description: Wireless communications in the terahertz band (0.1-10 THz) is a promising and key wireless technology enabling ultra-high data rate communication over multi-gigahertz-wide bandwidths, thus fulfilling the demand for denser networks. The complex propagation environment at such high frequencies introduces several challenges, such as high spreading and molecular absorption losses. As such, intelligent reflecting surfaces have been proposed as a promising solution to enable communication in the presence of blockage or to aid a resource-limited quasi-omnidirectional transmitter direct its radiated power. In this paper, we present a metallic reflectarray design achieving controlled non-specular reflection at true terahertz frequencies (i.e., 1-1.05 THz). We conduct extensive experiments to further characterize and validate its working principle using terahertz time-domain spectroscopy and demonstrate its effectiveness with information-carrying signals using a continuous-wave terahertz testbed. Our results show that the reflectarray can help facilitate robust communication links over non-specular paths and improve the reliability of terahertz communications, thereby unleashing the true potential of the terahertz band.

description: Relatively little is known about the association between Internet use and agricultural innovation adoption. To fill this void, this study examines the impact of Internet use on the adoption of sustainable agricultural practices (SAPs) and their heterogeneous effects on farm income and household income. Unlike previous studies that analyse the dichotomous decision of agricultural innovation adoption, this study captures the number of SAPs adopted. We apply both endogenous-treatment Poisson regression model and unconditional quantile regression model to analyse unique farm-level data collected from China. The empirical results show that Internet use exerts a positive and statistically significant impact on the number of SAPs adopted, and the joint effects of Internet use and SAP adoption on farm income and household income are heterogeneous. In particular, we show that households with lower farm income tend to benefit more from SAP adoption, while those with higher household income appear to benefit more from Internet use.

description: We investigate the Hubble tension in the non-flat Super-$Λ{\rm CDM}$ model. The non-flat Super-$Λ{\rm CDM}$ model extends the Super-$Λ{\rm CDM}$ model by including the spatial curvature as a free parameter. The Super-$Λ{\rm CDM}$ model extends the standard $Λ{\rm CDM}$ model of cosmology through additional parameters accounting for the possible effect of a trispectrum in the primordial fluctuations. In the cosmic microwave background data, this effect can be parameterized using parameters that change the observed angular power spectrum from the theoretical power spectrum due to a trispectrum that couples long and short wavelength modes. In this work, we perform Markov Chain Monte Carlo (MCMC) data analysis on the recent Planck 2018 temperature and polarization fluctuations data and the local Hubble constant measurements from supernovae data assuming a non-flat Super-$Λ{\rm CDM}$ model. We find that there is a preference for non-zero values of the spatial curvature parameter $Ω_k$ and the Super-$Λ{\rm CDM}$ parameter $A_0$ at a level of $Δχ^2$ improvement of approximately 23.

description: Background Wildfires and forestry activities such as post-fire salvage logging are altering North American forests on a massive scale. Habitat change and fragmentation on forested landscapes may threaten forest specialists, such as Pacific marten (Martes caurina), that require closed, connected, and highly structured habitats. Although marten use burned landscapes, it is unclear how these animals respond to differing burn severities, or how well they tolerate additional landscape change from salvage logging. Methods We used snow tracking and GPS collars to examine marten movements in three large burns in north-central Washington, USA (burned in 2006) and central British Columbia, Canada (burned in 2010 and 2017). We also assessed marten habitat use in relation to areas salvage-logged in the 2010 burn. We evaluated marten path characteristics in relation to post-fire habitat quality, including shifts in behaviour when crossing severely-disturbed habitats. Using GPS locations, we investigated marten home range characteristics and habitat selection in relation to forest cover, burn severity, and salvage logging. Results Marten in the 2006 burn shifted from random to directed movement in areas burned at high severity; in BC, they chose highly straight paths when crossing salvage-blocks and meadows. Collared marten structured their home ranges around forest cover and burn severity, avoiding sparsely-covered habitats and selecting areas burned at low severity. Marten selected areas farther from roads in both Washington and BC, selected areas closer to water in the 2006 burn, and strongly avoided salvage-logged areas of the 2010 burn. Marten home ranges overlapped extensively, including two males tracked concurrently in the 2010 burn. Conclusions Areas burned at low severity provide critical habitat for marten post-fire. Encouragingly, our results indicate that both male and female marten can maintain home ranges in large burns and use a wide range of post-fire conditions. However, salvage-logged areas are not suitable for marten and may represent significant barriers to foraging and dispersal.

description: The future 21 cm intensity mapping observations constitute a promising way to trace the matter distribution of the Universe and probe cosmology. Here we assess its capability for cosmological constraints using as a case study the BINGO radio telescope, that will survey the Universe at low redshifts ($0.13 < z < 0.45$). We use neural networks (NNs) to map summary statistics, namely, the angular power spectrum (APS) and the Minkowski functionals (MFs), calculated from simulations into cosmological parameters. Our simulations span a wide grid of cosmologies, sampled under the $Λ$CDM scenario, {$Ω_c, h$}, and under an extension assuming the Chevallier-Polarski-Linder (CPL) parameterization, {$Ω_c, h, w_0, w_a$}. In general, NNs trained over APS outperform those using MFs, while their combination provides 27% (5%) tighter error ellipse in the $Ω_c-h$ plane under the $Λ$CDM scenario (CPL parameterization) compared to the individual use of the APS. Their combination allows predicting $Ω_c$ and $h$ with 4.9% and 1.6% fractional errors, respectively, which increases to 6.4% and 3.7% under CPL parameterization. Although we find large bias on $w_a$ estimates, we still predict $w_0$ with 24.3% error. We also confirm our results to be robust to foreground contamination, besides finding the instrumental noise to cause the greater impact on the predictions. Still, our results illustrate the capability of future low redshift 21 cm observations in providing competitive cosmological constraints using NNs, showing the ease of combining different summary statistics.

description: As part of the environment-related stimulus package implemented in the wake of the 2008 global financial crisis, the Japanese government introduced tonnage and acquisition tax breaks and a subsidy programme for eco-friendly vehicles. However, there has been limited research on their economic effects. Therefore, this paper employs the event study methodology to examine not only the direct economic effects on automobile firms’ performance but also the spillover economic effects on automobile parts firms’ performance of the eco-car tax breaks and eco-car subsidy programme. Our results show that the eco-car tax breaks had lower positive economic direct effects and no positive spillover effects. The eco-car subsidy programme had more significantly positive direct economic effects and positive spillover effects. The eco-car tax breaks and eco-car subsidy programme had dissimilar economic effects because the length of the implementation period and preferential monetary benefits were different in each case. A mixed policy that combines the eco-car tax breaks and the eco-car subsidy programme is preferable to the eco-car tax breaks alone.

description: Emotional recognition through exploring the electroencephalography (EEG) characteristics has been widely performed in recent studies. Nonlinear analysis and feature extraction methods for understanding the complex dynamical phenomena are associated with the EEG patterns of different emotions. The phase space reconstruction is a typical nonlinear technique to reveal the dynamics of the brain neural system. Recently, the topological data analysis (TDA) scheme has been used to explore the properties of space, which provides a powerful tool to think over the phase space. In this work, we proposed a topological EEG nonlinear dynamics analysis approach using the phase space reconstruction (PSR) technique to convert EEG time series into phase space, and the persistent homology tool explores the topological properties of the phase space. We perform the topological analysis of EEG signals in different rhythm bands to build emotion feature vectors, which shows high distinguishing ability. We evaluate the approach with two well-known benchmark datasets, the DEAP and DREAMER datasets. The recognition results achieved accuracies of 99.37% and 99.35% in arousal and valence classification tasks with DEAP, and 99.96%, 99.93%, and 99.95% in arousal, valence, and dominance classifications tasks with DREAMER, respectively. The performances are supposed to be outperformed current state-of-art approaches in DREAMER (improved by 1% to 10% depends on temporal length), while comparable to other related works evaluated in DEAP. The proposed work is the first investigation in the emotion recognition oriented EEG topological feature analysis, which brought a novel insight into the brain neural system nonlinear dynamics analysis and feature extraction.

description: Fitness landscapes have historically been a powerful tool for analyzing the search space explored by evolutionary algorithms. In particular, they facilitate understanding how easily reachable an optimal solution is from a given starting point. However, simple fitness landscapes are inappropriate for analyzing the search space seen by selection schemes like lexicase selection in which the outcome of selection depends heavily on the current contents of the population (i.e. selection schemes with complex ecological dynamics). Here, we propose borrowing a tool from ecology to solve this problem: community assembly graphs. We demonstrate a simple proof-of-concept for this approach on an NK Landscape where we have perfect information. We then demonstrate that this approach can be successfully applied to a complex genetic programming problem. While further research is necessary to understand how to best use this tool, we believe it will be a valuable addition to our toolkit and facilitate analyses that were previously impossible.

description: Anthropogenic climate change is expected to be a major driver of worldwide biodiversity losses. Non-use values can play an important role in the evaluation of strategies to combat these losses or to reduce anthropogenic climate change. However, non-use values may not be transferrable across contexts with different pressures on biodiversity. Contrary to expectations in economic theory, they may be determined not only by outcomes, but also by what causes the outcomes. Given that no extant studies have specifically estimated the willingness to pay (WTP) for reducing the impact of climate change on biodiversity, we compare the WTP more generally for reducing anthropogenic and natural pressures on biodiversity. We conduct a meta-regression analysis informed by data obtained from stated preferences studies focusing on non-use values of biodiversity conservation. We assess whether non-use values for improving or avoiding losses of habitats and species are affected by policy responses addressing anthropogenic or natural pressures. We estimate meta-regression models in which we explain the variation in biodiversity non-use values by accounting for the observed heterogeneity in good, methodology, sample, and context characteristics. We estimate meta-regression models using 159 observations from 62 publications. The models suggest that non-use values for biodiversity conservation addressing anthropogenic pressures may be 95–131 percent larger than those facing natural pressures. We also find that non-use values are generally not sensitive to habitat types or the scope of species preservation. The evaluation of climate policy in terms of biodiversity non-use values should be based on valuations of the effect of anthropogenic pressures on biodiversity, instead of inferring these benefits from a wide variety of existing studies. Furthermore, there is a clear need for additional valuation research focusing on estimating non-use values, specifically for climate change-induced biodiversity losses.

description: Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver deep observations for potentially of millions of objects with visible tidal features, but the inference of galaxy interaction histories from such features is not straightforward. Utilising automated techniques and human visual classification in conjunction with realistic mock images produced using the NEWHORIZON cosmological simulation, we investigate the nature, frequency and visibility of tidal features and debris across a range of environments and stellar masses. In our simulated sample, around 80 per cent of the flux in the tidal features around Milky Way or greater mass galaxies is detected at the 10-year depth of the Legacy Survey of Space and Time (30-31 mag / sq. arcsec), falling to 60 per cent assuming a shallower final depth of 29.5 mag / sq. arcsec. The fraction of total flux found in tidal features increases towards higher masses, rising to 10 per cent for the most massive objects in our sample (M*~10^{11.5} Msun). When observed at sufficient depth, such objects frequently exhibit many distinct tidal features with complex shapes. The interpretation and characterisation of such features varies significantly with image depth and object orientation, introducing significant biases in their classification. Assuming the data reduction pipeline is properly optimised, we expect the Rubin Observatory to be capable of recovering much of the flux found in the outskirts of Milky Way mass galaxies, even at intermediate redshifts (z<0.2).

description: Agricultural productivity in many developing countries remains low owing mostly to the low adoption of readily available modern technologies such as modern seeds, chemical fertilisers and mechanized irrigation. To understand if relaxing credit constraints increases the adoption of agricultural technologies, we use results from a field experiment designed to estimate the effect of access to microcredit on agricultural technology adoption. We find mere offering of microcredit to smallholder farmers does not lead to the adoption of agricultural technologies. Nevertheless, there is strong evidence of a heterogeneous treatment effects: borrowers with medium-sized farms are 13.3 per cent more likely to adopt modern technologies. In addition, less-risk averse borrowers, and present-biased borrowers are 13.1 per cent and 12.3 per cent more likely to adopt modern technologies.

description: Personalized PageRank (PPR) is a popular node proximity metric in graph mining and network research. Given a graph G=(V,E) and a source node $s \in V$, a single-source PPR (SSPPR) query asks for the PPR value $\vpi(u)$ with respect to s, which represents the relative importance of node u in the context of the source node s. Among existing algorithms for SSPPR queries, LocalPush is a fundamental method which serves as a cornerstone for subsequent algorithms. In LocalPush, a push operation is a crucial primitive operation, which distributes the probability at a node u to ALL u's neighbors via the corresponding edges. Although this push operation works well on unweighted graphs, unfortunately, it can be rather inefficient on weighted graphs. In particular, on unbalanced weighted graphs where only a few of these edges take the majority of the total weight among them, the push operation would have to distribute insignificant probabilities along those edges which just take the minor weights, resulting in expensive overhead. To resolve this issue, we propose the EdgePush algorithm, a novel method for computing SSPPR queries on weighted graphs. EdgePush decomposes the aforementioned push operations in edge-based push, allowing the algorithm to operate at the edge level granularity. Hence, it can flexibly distribute the probabilities according to edge weights. Furthermore, our EdgePush allows a fine-grained termination threshold for each individual edge, leading to a superior complexity over LocalPush. Notably, we prove that EdgePush improves the theoretical query cost of LocalPush by an order of up to O(n) when the graph's weights are unbalanced, both in terms of $\ell_1$-error and normalized additive error. Our experimental results demonstrate that EdgePush significantly outperforms state-of-the-art baselines in terms of query efficiency on large motif-based and real-world weighted graphs.

description: The Gas Electron Multiplier (GEM) is a new age detector, which can handle the high flux of particles. The GEM foil, which is constructed using 50$μ$m highly insulating foil (Kapton/Apical) coated with 5$μ$m layers of copper, on both sides, with a network of specifically shaped holes is the major component of these detectors. The European Center for Nuclear Research (CERN) has been the sole supplier of the GEM foils until recently when a few other companies started manufacturing GEM foils under the transfer of technology (TOT) agrement from CERN. Techtra is one such company in Europe which gained a right to use CERN developed technology in order to produce commercially viable GEM foils. Micropack Pvt. Ltd. is another company in India which has successfully manufactured good quality GEM foils. Due to the microscopic structure of holes and dependence on the electric field inside, it becomes essential to study the defect and uniformity of holes along with the electrical property of foils under ambient conditions. In this work we are reporting the tests condition of Techtra GEM foils. We report on the development of a cost effective and efficient technique to study the GEM foils holes geometry, distribution, and defects. We also report on the electrical properties of these foils like leakage current, stability, and discharges. At the detector level, we describe the high voltage (HV) response, gain, uniformity, and stability. The GEMs have been proposed to have a wider applications, so we performed a feasibility study to utilize these for the imaging. We irrediated various objects of varying density with X-rays and reconstructed the images. The reconstructed image shows a good distinction between materials of different densities, which can be very useful in various applications like medical imaging or cargo imaging.

description: Layered CoO$_2$ is of great interest for its promising properties but is meta-stable in its bulk form. CoO$_2$ was synthesized by converting the quasi-one-dimensional crystal structure of bulk Ca$_3$Co$_2$O$_6$ via a hydrothermal treatment. The resulting nanostructures were predominantly nanoscrolls with very thin walls, which exhibit long-term stability. A detailed structural investigation reveals that the CoO$_2$ is found to crystallize in monoclinic form, similar to the related CaCoO$_2$-CoO$_2$ misfit structure. Individual nanoscrolls are characterized electrically and show a p-type semiconducting nature with a high current-carrying capacity of 4$\cdot$10$^5$ A cm$^{-2}$ and an extremely high breakdown voltage of up to 270 kV/cm. The results demonstrate the possibility to stabilize meta-stable materials in low-dimensional forms and a promising application of the nanoscrolls as interconnect in high-voltage electronic circuitry.

description: This article is a critical analysis of the High Court's decision in Telstra Corporation Ltd v The Commonwealth, in which Telstra argued unsuccessfully that the application of the telecommunications access regime, established under Part XIC of the Trade Practices Act, to the ULLS and LSS, was an acquisition of property
on unjust terms, contrary to s 51(xxxi) of the Constitution. Although the article does not disagree with the High Court's decision on the facts of this case, it contends that the narrow focus of the judgment, which is based mainly on the historically contingent circumstances that a telecommunications access regime was implemented prior to the privatisation of Telstra, provides little guidance about the extent to which future regulatory interventions may breach s 51(xxxi). The court's expansive understanding of what amounts to an 'acquisition of property' under s 51(xxxi), however, suggests that proposals for greater regulatory intervention, such as proposals for structural separation involving, for example, divestiture of the CAN, may well amount to a breach of s 51(xxxi), thereby
requiring payment of compensation to Telstra.

description: LIGNICOAT partner VTT, the Technical Research Centre of Finland, presented an oral presentation titled “Fractionation of Kraft Lignin for Production of Alkyd Resin for Bio-based Coatings” at the 2024 AIChE Annual Meeting. The AIChE Annual Meeting occurred in San Diego, California (USA).

The presentation focuses on using lignin-based alkyd resins to coat metal surfaces.

VTT and BARPIMO researchers explored the potential of using kraft lignin (KL) as a replacement for phthalic anhydride in alkyd resins to increase the bio-content of the material. VTT researchers focused on replacing phthalic anhydride with KL to increase the bio-content of the material. Solvent fractionation was investigated to improve lignin’s solubility and reactivity. This process yielded more uniform, lower molecular weight lignin fractions with higher phenolic OH and COOH group content. These fractions were then used to develop alkyd resins and coatings that showed promising performance compared to commercial standards.

The presentation also addressed the issue of odor and volatile organic compound (VOC) release associated with low molecular weight KL. VTT and BARPIMO identified potential strategies to reduce these emissions.

description: In this paper, we present an early version of a SYCL-based FFT library, capable of running on all major vendor hardware, including CPUs and GPUs from AMD, ARM, Intel and NVIDIA. Although preliminary, the aim of this work is to seed further developments for a rich set of features for calculating FFTs. It has the advantage over existing portable FFT libraries in that it is single-source, and therefore removes the complexities that arise due to abundant use of pre-process macros and auto-generated kernels to target different architectures. We exercise two SYCL-enabled compilers, Codeplay ComputeCpp and Intel's open-source LLVM project, to evaluate performance portability of our SYCL-based FFT on various heterogeneous architectures. The current limitations of our library is it supports single-dimension FFTs up to $2^{11}$ in length and base-2 input sequences. We compare our results with highly optimized vendor specific FFT libraries and provide a detailed analysis to demonstrate a fair level of performance, as well as potential sources of performance bottlenecks.

description: Reducing errors in quantum gates is critical to the development of quantum computers. To do so, any distortions in the control signals should be identified, however, conventional tools are not always applicable when part of the system is under high vacuum, cryogenic, or microscopic. Here, we demonstrate a method to detect and compensate for amplitude-dependent phase changes, using the qubit itself as a probe. The technique is implemented using a microwave-driven trapped ion qubit, where correcting phase distortions leads to a three-fold improvement in single-qubit gate error, to attain state-of-the-art performance benchmarked at $1.6(4)\times 10^{-6}$ error per Clifford gate.

description: Background Whole-of-community interventions hold promise in addressing childhood obesity. The COMPACT Stakeholder-driven Community Diffusion theory posits that stakeholders’ knowledge of childhood obesity prevention efforts and engagement with the issue contribute to successful intervention implementation. Building on completed formative research and pilot testing, we describe the validation and refinement of knowledge and engagement measures. Methods We assessed content validity using a modified Delphi process with science (n=18) and practice-based (n=16) experts. Next, we refined the survey based on input from science- and practice-based experts, cognitive response testing, and item analysis of extant survey data. Field testing of the refined survey involved community stakeholders in Greenville County, South Carolina (n=50), East Boston, Massachusetts (n=30), and Tucson, Arizona (n=84) between 2019 and 2020. Construct validity was assessed with confirmatory factor analysis (CFA). Two-week test-retest reliability was assessed among a subsample of 14 paired respondents in South Carolina. Results Experts rated existing knowledge domains (intervention factors, roles, sustainability, problem, resources) and engagement domains (dialogue/mutual learning, flexibility, influence/power, leadership/stewardship, trust) highly for their importance in addressing childhood obesity. Expert input resulted in 11 new knowledge items and 7 new engagement items that mapped onto existing domains. Correspondingly, two domain names were modified: implementation/sustainability and trust/trustworthiness. We also eliminated 8 extant items (4 knowledge and 4 engagement) and adapted item language for comprehension and consistency. Further modifications based on CFA results and item analyses resulted in 23 knowledge items across four domains (roles and resources merged) and 23 engagement items across five domains. Modified knowledge and engagement scales had adequate fit and strong item factor loadings (most >0.7 and all >0.5). Knowledge (α=0.86–0.87) and engagement (α=0.75–0.90) subscales had high internal scale consistency. Knowledge intraclass correlation coefficients (ICCs) for test-retest agreement of subscale scores ranged from 0.50 for intervention factors to 0.86 for roles/resources. For engagement subscale scores, ICCs ranged from 0.70 for trust/trustworthiness to 0.96 for leadership/stewardship. Conclusions Findings from this multi-method survey development process increase our confidence of the knowledge and engagement measures’ content validity, construct validity, and reliability.

description: We present a computational framework for the simulations of powder-bed fusion of metallic alloys, which combines: (1) CalPhaD calculations of temperature-dependent alloy properties and phase diagrams, (2) macroscale finite element (FE) thermal simulations of the material addition and fusion, and (3) microscopic phase-field (PF) simulations of solidification in the melt pool. The methodology is applied to simulate the selective laser melting (SLM) of an Inconel 718 alloy using realistic processing parameters. We discuss the effect of temperature-dependent properties and the importance of accounting for different properties between the powder bed and the dense material in the macroscale thermal simulations. Using a two-dimensional longitudinal slice of the thermal field calculated via FE simulations, we perform an appropriately-converged PF solidification simulation at the scale of the entire melt pool, resulting in a calculation with over one billion grid points, yet performed on a single cluster node with eight graphics processing units (GPUs). These microscale simulations provide new insight into the grain texture selection via polycrystalline growth competition under realistic SLM conditions, with a level of detail down to individual dendrites.

description: Do drinkers respond to prices signals in the usual way by economising on beverages with higher prices and vice versa? Is the currency unit used in different countries irrelevant, or are drinkers subject to money illusion? Are the substitution effects of price changes symmetric? More fundamentally, can drinking patterns be adequately accounted for by the conventional utility-maximising approach? If so, how does consumption of beer, wine and spirits interact (if at all) in generating utility? According to the most recent data from the International Comparisons Program, on average, consumers in countries in the bottom quartile of the global income distribution devote something approaching one-half of all expenditures to food, while this falls to about 11% in the richest countries, in accordance with Engel’s law. The share for alcohol also drops, but much slower, so drinking rises noticeably relative to food as income increases. The within-alcohol distribution of spending (beer, wine and spirits) also changes quite dramatically. We use these cross-country data to address the above research questions. To visualise the data, we plot the budget shares for beer, wine and spirits in the form of a “drinking triangle”, which highlights the dominant beverage in each country. We also employ a Divisia-index-number approach to summarise the degree of price-quantity covariation. We cross-classify consumption and prices of beer, wine and spirits for nonparametric tests of the law of demand that higher prices lead to reduced consumption and vice versa. A system-wide model is estimated for the demand for beer, wine and spirits. As there is no unique way of ordering countries, a “levels version” of a differential system (similar to the Rotterdam model) is used. The system is used to test the hypotheses of homogeneity (the absence of money illusion) and symmetry of the substitution effects. For a substantial majority of countries, the Divisia price-quantity correlation is negative, which is suggestive evidence in favour of the economic approach to drinking. In the main, the results here support the law of demand. The hypotheses of homogeneity and symmetry cannot be rejected. Tests also reveal the coefficients are reasonable stable across countries, which sheds some light on the question of the similarity of tastes. Estimated price elasticities are tabulated for each beverage.
