description: In 2019 the Sub-Commission on the Ordovician System approved the Xiaoyangqiao section, North China as a new ASSP section for the base of the Ordovician System. The sedimentary succession of the section is exposed in a natural outcrop near the Dayangcha Village at a position of 42°3'24''N, 126°42'21''E. It has a well-preserved, abundant and diverse fossil record across the boundary with key markers (conodonts and graptolites), which provide improved intercontinental correlation of the Cambrian– Ordovician boundary. The appearance of the first planktonic graptolites is immediately below the base of the Cordylodus lindstromi Conodont Zone. Other fossils, including acritarchs, brachiopods and trilobites are also present in the Xiaoyangqiao ASSP section. Non-biotic secondary global markers near the base of the Ordovician System include a positive carbon isotopic excursion with the maximum peak (named HSS) below the boundary, a prominent unnamed negative peak immediately below the boundary and a prominent carbon isotope excursion with positive peaks above the boundary. The latter excursion is associated with the appearance of the planktonic graptolites in the Ordovician. The strength of the Xiaoyangqiao ASSP section is the correlation between the conodonts and graptolites, correspondence of sea-level lowstands, and the matches of geochemical parameters.

description: Marketing agencies-in-common (MACs) have been used by farmer cooperatives for many years to accomplish specific marketing activities. Relatively scant attention or concern has been given to adequately defining MACs in terms of how they differ from other forms of organization, particularly from other federated cooperatives. Distinctions can be made in terms of the development and ownership of assets. Members of MACs retain individual member ownership of assets, with their MAC providing various supplementary functions such as group communications and product selling coordination. Members often have assets that are highly specific to their own marketing programs and have developed significant expertise in their respective industries. With a membership of this kind, MACs are governed in a multiple principal structure, in contrast to the usual generalized single principal-agent relationship that prevails in most cooperative forms of organization.

description: During the months of May, June, July and August 2019 the Red Band Difference algorithm was tested over Irish waters to assess its suitability for the Irish harmful algal bloom alert system. Over the 4 weeks of June an extensive localised surface phytoplankton bloom formed in the Celtic Sea, south of Ireland. Satellite imagery from the Sentinel-3a’s Ocean and Land Colour Instrument, processed using the Red Band Difference algorithm detected the bloom in surface shelf waters and helped monitor its movement. Daily satellite images indicated that the bloom appeared at the sea surface on the 2nd June 2019 and peaked in size and surface abundance in offshore shelf waters within 4 weeks, remnants remained at the surface into July. A particle tracking approach was used to replicate oceanic circulation patterns in the vicinity of the observed algal bloom and estimate its trajectory. The initial horizontal distribution of particles in the tracking model were based on a satellite imagery polygon of the bloom when it first appeared in surface waters. Good agreement was observed between satellite imagery of the bloom and the particle tracking model. In situ sampling efforts from a research cruise and the national inshore phytoplankton monitoring programme confirmed that Karenia mikimotoi was the causative organism of the bloom. This pilot study shows great potential to use the Red Band Difference algorithm in the existing Irish harmful algal bloom alert system. In addition, satellite ocean colour data combined with particle tracking model estimates can be a useful tool to monitor high biomass harmful algal bloom forming species, such as Karenia mikimotoi, in surface coastal waters around Ireland and elsewhere.

description: We consider the problem of correcting the errors incurred from sending quantum information through a noisy quantum environment by using classical information obtained from a measurement on the environment. For discrete time Markovian evolutions, in the case of fixed measurement on the environment, we give criteria for quantum information to be perfectly corrigible and characterize the related feedback. Then we analyze the case when perfect correction is not possible and, in the qubit case, we find optimal feedback maximizing the channel fidelity.

Investigating the Role of Structural Water on the Electrochemical Properties of $α$-V$_2$O$_5$ through Density Functional Theory

description: The $α$ polymorph of V$_2$O$_5$ is one of the few known cathodes capable of reversibly intercalating multivalent ions such as Mg, Ca, Zn and Al, but suffers from sluggish diffusion kinetics. The role of H$_2$O within the electrolyte and between the layers of the structure in the form of a xerogel/aerogel structure, though, has been shown to lower diffusion barriers and lead to other improved electrochemical properties. This density functional theory study systematically investigates how and why the presence of structural H$_2$O within $α$-V$_2$O$_5$ changes the resulting structure, voltage, and diffusion kinetics for the intercalation of Li, Na, Mg, Ca, Zn, and Al. We found that the coordination of H$_2$O molecules with the ion leads to an improvement in voltage and energy density for all ions. This voltage increase was attributed to the extra host sites for electrons present with H$_2$O, thus leading to a stronger ionization of the ion and a higher voltage. We also found that the increase in interlayer distance and a potential "charge shielding" effect drastically changes the electrostatic environment and the resulting diffusion kinetics. For Mg and Ca, this resulted in a decrease in diffusion barrier from 1.3 eV and 2.0 eV to 0.89 eV and 0.4 eV, respectively. We hope that our study motivates similar research regarding the role of water in both V$_2$O$_5$ xerogels/aerogels and other layered transition metal oxides.

description: Elucidating the underlying principles behind band gap engineering is paramount for the successful implementation of semiconductors in photonic and optoelectronic devices. Recently it has been shown that the band gap of a wide and direct band gap semiconductor, such as ZnO, can be modified upon co-crystallization with amino acids, with the role of the biomolecules remaining unclear. Here, by probing and modeling the light emitting properties of ZnO-amino acid co-crystals, we identify the amino acids role on this band gap modulation and demonstrate their effective chirality transfer to the inter-band excitations in ZnO. Our 3D quantum model suggests that the strong band edge emission blue shift in the co-crystals can be explained by a quasi-periodic distribution of amino acid potential barriers within the ZnO crystal lattice. Overall, our findings indicate that biomolecule co-crystallization can be used as a truly bio-inspired means to induce chiral quantum confinement effects in quasi-bulk semiconductors.

description: During natural vision, our brains are constantly exposed to complex, but regularly structured, environments. Real-world scenes are defined by typical part–whole relationships, where the meaning of the whole scene emerges from configurations of localized information present in individual parts of the scene. Such typical part–whole relationships suggest that information from individual scene parts is not processed independently, but that there are mutual influences between the parts and the whole during scene analysis. Here, we review recent research that used a straightforward, but effective approach to study such mutual influences: By dissecting scenes into multiple arbitrary pieces, these studies provide new insights into how the processing of whole scenes is shaped by their constituent parts and, conversely, how the processing of individual parts is determined by their role within the whole scene. We highlight three facets of this research: First, we discuss studies demonstrating that the spatial configuration of multiple scene parts has a profound impact on the neural processing of the whole scene. Second, we review work showing that cortical responses to individual scene parts are shaped by the context in which these parts typically appear within the environment. Third, we discuss studies demonstrating that missing scene parts are interpolated from the surrounding scene context. Bridging these findings, we argue that efficient scene processing relies on an active use of the scene's part–whole structure, where the visual brain matches scene inputs with internal models of what the world should look like.

description: Most stars previously identified as Maunder minimum stars are old stars evolved off of the main sequence. Analysis of activity measurements from the California and Carnegie Planet Search program stars and Hipparcos parallaxes implies that the canonical age-chromospheric activity relation breaks down for stars older than $\sim 6$ Gyr when activity is calculated from Mount Wilson S values. Stars only 1 magnitude above the main sequence exhibit significantly suppressed activity levels which have been mistaken for examples of Maunder minimum behavior.

description: Using spectral-element and adjoint methods, we investigate body waves interacting with the Earth's most dramatic interface, the core-mantle boundary (CMB). Intermediate-to-high frequency seismograms are computed incorporating topography models. We analyse the sensitivity of many seismic phases interacting with the interface. The study aims at showing effects of CMB structure on synthetics and highlights difficulties of imaging this region due to strong trade-off between velocity variations and topography. Synthetic waveforms computed at dominant periods of 6-18 seconds are used in order to observe time shifts due to topography and calculate the adjoint sensitivity kernel. We focus on diffracted, core reflected and refracted P and S waves. The sensitivity kernel depicts first Fresnel zones of these phases and others that may contribute to narrow time window, although unpredicted by ray theory. We perform comparisons between time shifts due to topography models made on full-waveform synthetics to ray theoretical predictions to assess methods usually deployed for imaging CMB. This shows that for most phases ray theory performs well enough with some accuracy loss. We propose that using relevant seismic phases simultaneously in full-waveform inversion may improve CMB topography imaging. However, it seems necessary to jointly invert for velocity variations due to D\" layer, which is so far poorly understood and presents a challenge when it comes to identifying its effects on traveltime data. In our further research, a FWI workflow is being developed and aims at addressing these issues.
COVID-19 and the difficulty of inferring epidemiological parameters from clinical data

description: Knowing the infection fatality ratio (IFR) is of crucial importance for evidence-based epidemic management: for immediate planning; for balancing the life years saved against the life years lost due to the consequences of management; and for evaluating the ethical issues associated with the tacit willingness to pay substantially more for life years lost to the epidemic, than for those to other diseases. Against this background Verity et al. (2020, Lancet Infections Diseases) have rapidly assembled case data and used statistical modelling to infer the IFR for COVID-19. We have attempted an in-depth statistical review of their approach, to identify to what extent the data are sufficiently informative about the IFR to play a greater role than the modelling assumptions, and have tried to identify those assumptions that appear to play a key role. Given the difficulties with other data sources, we provide a crude alternative analysis based on the Diamond Princess Cruise ship data and case data from China, and argue that, given the data problems, modelling of clinical data to obtain the IFR can only be a stop-gap measure. What is needed is near direct measurement of epidemic size by PCR and/or antibody testing of random samples of the at risk population.

Techniques for enhancing the prices growers receive and nonprice services such associations provide their farmermembers are presented. Future challenges and opportunities for producer bargaining associations are also discussed.

description: Cooperatives are organized to be democratic. However, large membership size can create problems for democratic process and governance. Attending meetings and casting votes may not be enough to preserve democratic characteristics. This report develops a set of propositions-a theory-for structuring membership to improve democratic opportunities and responsiveness. Aspects of these propositions are tested against data from dairy herd improvement cooperatives in Wisconsin and are supported. These propositions suggest potential structural design options, given specific stressors in the membership environment, and the management and operations environment.

description: A rotating detonation combustor (RDC) is a novel approach to achieving pressure gain combustion. Due to the steady propagation of the detonation wave around the perimeter of the annular combustion chamber, the RDC dynamic behavior is well suited to analysis with reduced-order techniques. For flow fields with such coherent aspects, the dynamic mode decomposition (DMD) has been shown to capture well the dominant oscillatory features corresponding to stable limit-cycle or quasi-periodic behavior within its dynamic modes. Details regarding the application of the technique to RDC—such as the number of frames, the effect of subtracting the temporal mean from the processed dataset, the resulting dynamic mode shapes, and the reconstruction of the dynamics from a reduced set of dynamic modes—are analyzed and interpreted in this study. The DMD analysis is applied to two commonly observed operating conditions of rotating detonation combustion, viz., (1) a single spinning wave with weak counter-rotating waves and (2) a clapping operating mode with two counter-propagating waves at equal speed and strength. We show that care must be taken when applying DMD to RDC datasets due to the presence of standing waves (expressed as either counter-propagating azimuthal waves or longitudinal pulsations). Without accounting for these effects, the reduced-order reconstruction fails using the standard DMD approach. However, successful application of the DMD allows for the reconstruction and separation of specific wave modes, from which models of the stabilization and propagation of the primary and counter-rotating waves can be derived.

description: Growth arrest-specific 1 (GAS1) acts as a co-receptor to patched 1, promoting sonic hedgehog (SHH) signaling in the developing nervous system. GAS1 mutations in humans and animal models result in forebrain and craniofacial malformations, defects ascribed to a function for GAS1 in SHH signaling during early neurulation. Here, we confirm loss of SHH activity in the forebrain neuroepithelium in GAS1-deficient mice and in induced pluripotent stem cell-derived cell models of human neuroepithelial differentiation. However, our studies document that this defect can be attributed, at least in part, to a novel role for GAS1 in facilitating NOTCH signaling, which is essential to sustain a persistent SHH activity domain in the forebrain neuroepithelium. GAS1 directly binds NOTCH1, enhancing ligand-induced processing of the NOTCH1 intracellular domain, which drives NOTCH pathway activity in the developing forebrain. Our findings identify a unique role for GAS1 in integrating NOTCH and SHH signal reception in neuroepithelial cells, and they suggest that loss of GAS1-dependent NOTCH1 activation contributes to forebrain malformations in individuals carrying GAS1 mutations.

description: The effects of dynamic localization in a solid-state system -- a quantum dot -- are considered. The theory of weak dynamic localization is developed for non-interacting electrons in a closed quantum dot under arbitrary time-dependent perturbation and its equivalence to the theory of weak Anderson localization is demonstrated. The dephasing due to inelastic electron scattering is shown to destroy the dynamic localization in a closed quantum dot leading to the classical energy absorption at times much greater than the inelastic scattering time. Finally a realistic case of a dot weakly connected to leads is studied and it is shown that the dynamic localization may lead to a drastic change of the shape of the Coulomb blockade peak in the dc conductance vs the gate voltage.

description: The hype around self-driving cars has been growing over the past years and has sparked much research. Several modules in self-driving cars are thoroughly investigated to ensure safety, comfort, and efficiency, among which the controller is crucial. The controller module can be categorized into longitudinal and lateral controllers in which the task of the former is to follow the reference velocity, and the latter is to reduce the lateral displacement error from the reference path. Generally, a tuned controller is not sufficient to perform in all environments. Thus, a controller that can adapt to changing conditions is necessary for autonomous driving. Furthermore, these controllers often depend on vehicle models that also need to adapt over time due to varying environments. This paper uses graphs to present novel techniques to learn the vehicle model and the lateral controller online. First, a heterogeneous graph is presented depicting the current states of and inputs to the vehicle. The vehicle model is then learned online using known physical constraints in conjunction with the processing of the graph through a Graph Neural Network structure. Next, another heterogeneous graph - depicting the transition from current to desired states - is processed through another Graph Neural Network structure to generate the steering command on the fly. Finally, the performance of this self-learning model-based lateral controller is evaluated and shown to be satisfactory on an open-source autonomous driving platform called CARLA.

description: A partir da análise dos princípios de governo aberto e modelos e práticas de gestão de transportes implementados em cidades do mundo e no Brasil, investigou-se como as iniciativas de transparência, participação cidadã e colaboração podem contribuir para a modernização e democratização das políticas de mobilidade urbana no Rio de Janeiro. O estudo considera a possível inserção deste município no contexto da Parceria para Governo Aberto e nas ações previstas no 6º Plano de Ação Nacional de 2023, que incluem a abertura de dados e o envolvimento da sociedade civil no processo de tomada de decisões. O trabalho apresenta um panorama das políticas adotadas na Região Metropolitana do Rio de Janeiro, avaliando seus impactos na eficiência, acessibilidade e sustentabilidade das políticas de transportes. Conclui-se que, embora a aplicação dos princípios de Governo Aberto no transporte urbano possa gerar avanços significativos, ainda há barreiras a serem superadas para garantir uma participação mais ampla e efetiva da população na cidade analisada. Assim, o estudo de caso do Rio de Janeiro serve como referência para outras cidades brasileiras que também poderiam adotar modelos de governança mais “abertos” para garantir uma melhor integração tanto institucional como social.

description: This report presents information for 1983 through 1991 on the physical and financial structure adjustments made by local first-handlers-of-grain cooperatives in three major wheat areas-Northern Plains, Southern Plains, and Pacific Northwest. They had annual total sales of at least $5 million, more than half in grain. Most associations also handled farm supplies and all provided related services. Local cooperative grain handlers faced abrupt changes in export markets for grains and oilseeds, shifts in Government policy, and occasional drought, accompanied by wide swings in grain prices. Most associations represented in this report adjusted successfully to changing economic conditions through sound financial management of particularly long-term debt and operating capital. The economic position of most locals improved in the latter half of the period due in part to increased patronage from their regional cooperatives.

description: Thermal fusion plasmas initiated by standing whistler waves are investigated numerically by two- and one-dimensional Particle-in-Cell simulations. When a standing whistler wave collapses due to the wave breaking of ion plasma waves, the energy of the electromagnetic waves transfers directly to the ion kinetic energy. Here we find that the ion heating by the standing whistler wave is operational even in multi-dimensional simulations of multi-ion species targets, such as deuterium-tritium (DT) ices and solid ammonia borane (H$_6$BN). The energy conversion efficiency to ions becomes as high as 15% of the injected laser energy, which depends significantly on the target thickness and laser pulse duration. The ion temperature could reach a few tens of keV or much higher if appropriate laser-plasma conditions are selected. DT fusion plasmas generated by this method must be useful as efficient neutron sources. Our numerical simulations suggest that the neutron generation efficiency exceeds 10$^9$ n/J per steradian, which is beyond the current achievements of the state-of-the-art laser experiments. The standing whistler wave heating would expand the experimental possibility for an alternative ignition design of magnetically confined laser fusion, and also for more difficult fusion reactions including the aneutronic proton-boron reaction.

description: Building on a previous proposal for the entanglement of electron-hole pairs in the Fermi sea, we show how 3 qubits can be entangled without using electron-electron interactions. As in the 2-qubit case, this electronic scheme works even if the sources are in (local) thermal equilibrium -- in contrast to the photonic analogue. The 3 qubits are represented by 4 edge-channel excitations in the quantum Hall effect (2 hole excitations plus 2 electron excitations with identical channel index). The entangler consists of an adiabatic point contact flanked by a pair of tunneling point contacts. The irreducible 3-qubit entanglement is characterized by the tangle, which is expressed in terms of the transmission matrices of the tunneling point contacts. The maximally entangled Greenberger-Horne-Zeilinger (GHZ) state is obtained for channel-independent tunnel probabilities. We show how low-frequency noise measurements can be used to determine an upper and lower bound to the tangle. The bounds become tighter the closer the electron-hole state is to the GHZ state.

description: AbstractThe Nigerian Data Protection Regulation (NDPR), introduced in 2019, represents a significant milestone in Nigeria’s data protection and privacy landscape. Designed to regulate the collection, processing, and storage of personal data, the NDPR has imposed new compliance obligations on corporate entities operating within Nigeria. This article examines the regulatory impact of the NDPR on businesses, exploring its effectiveness in safeguarding data privacy, its enforcement mechanisms, and the challenges companies face in achieving compliance.Through a comparative analysis with global data protection frameworks such as the EU's General Data Protection Regulation (GDPR), this article assesses whether the NDPR has successfully strengthened corporate accountability and consumer trust. It further highlights the practical implications for businesses, including financial penalties for non-compliance, the role of Data Protection Officers (DPOs), and the evolving enforcement landscape under the Nigeria Data Protection Commission (NDPC).Ultimately, this article argues that while the NDPR has made significant strides in promoting data protection awareness and corporate responsibility, gaps in enforcement, inadequate compliance infrastructure, and regulatory ambiguities still hinder its full impact. Recommendations for policy improvements and enhanced regulatory oversight are provided to ensure that the NDPR remains a dynamic and effective tool for data protection in Nigeria’s digital economy.

description: This work presents a numerical study of detonation initiation by means of a focusing shock wave. The investigated geometry is a part of a pulsed detonation combustion chamber, consisting of a circular pipe in which the flow is obstructed by a single convergent–divergent axisymmetric nozzle. This obstacle acts as a focusing device for an incoming shock wave, serving as a low-energy detonation initiator. The chamber is filled with stoichiometric premixed hydrogen-enriched air. The simulation uses a one-step chemical model with variable parameters optimized by the adjoint approach in terms of the induction time τ c . The model reproduces τ c of a complex kinetics model in the range of pressures and temperatures appearing at the focusing point. The results give a comprehensive description of the shock-induced detonation initiation, which is the mechanism for the deflagration-to-detonation transition in this type of configurations. Potential geometry design improvements for technical applications are discussed. The first attempt to parameterize the transition process is also undertaken.

description: Large-scale earthquake sequence simulations using the boundary element method (BEM) incur extreme computational costs through multiplying a dense matrix with a slip rate vector. Hierarchical matrices (H-matrices) have often been used to accelerate this multiplication. However, the complexity of the structures of the H-matrices and the communication costs between processors limit their scalability, and they therefore cannot be used efficiently in distributed memory computer systems. Lattice H-matrices have recently been proposed as a tool to improve the parallel scalability of H-matrices. In this study, we developed a method for earthquake sequence simulations applicable to 3D nonplanar faults with lattice H-matrices. We present a simulation example and verify the mesh convergence of our method for a 3D nonplanar thrust fault using rectangular and triangular elements. We also performed performance and scalability analyses of our code. Our simulations, using over 10^5 degrees of freedom, demonstrated a parallel acceleration beyond 10^4 MPI processors and a >10-fold acceleration over the best performance when the normal H-matrices are used. Using this code, we can perform unprecedented large-scale earthquake sequence simulations on geometrically complex faults with supercomputers. The software HBI is made an open-source and freely available.

Electromechanical coupling in three-phase fibrous paper
Creators: name: Liang, Tongfen
Publisher: name: No Publisher Supplied
Year: 2021

description: This work aims to develop a scalable process of fabricating highly porous composite paper with tunable conductivity and put forward an open-source workflow to model a three-phase stochastic fibrous network. In the experimental studies, this work employs a foam-laying method to fabricate composite paper with carbon black as conductive fillers and cellulose fibers as the matrix. By embossing such paper, its porosity decreases while its conductivity increases. Tuning the porosity of composite paper alters the magnitude and trend of conductivity over a spectrum of concentrations of conductive particles. The largest increase in conductivity from 8.38×10-6 S/m to 2.5×10-3 S/m by a factor of ~300 occurred at a percolation threshold of 3.8 wt% (or 0.36 vol%) with the composite paper plastically compressed by 410 MPa, which caused a decrease of porosity from 88% to 42% on average. Our composite paper showed stable piezoresistive responses within a broad pressure range from 1 kPa up to 5.5 MPa for 800 cycles. The piezoresistive sensitivities of the composite paper were concentration-dependent and decreased with pressure. Composite paper with 7.5 wt% CB had sensitivities of −0.514 kPa−1 over applied pressures ranging from 1 kPa to 50 kPa and −0.215 kPa−1 from 1 kPa to 250 kPa. This piezoresistive paper with embossed patterns enabled touch sensing and detection of damage from darts and punches. Understanding the percolation behavior of three-phase composites (cellulose fibers/conductive particles/air) and their response to damage, pressure, and processing conditions has the potential to enable scalable applications in prosthetics and robotics, haptic feedback, or structural health monitoring on expansive surfaces of buildings and vehicles. Few theoretical models capture piezoresistive responses of three-phase conductive composites. To interpret the electromechanical coupling of our piezoresistive composite and provide some insight in designing customized composite, we built multiscale models to simulate nanoparticle-nanoparticle interaction and fiber-fiber interaction. We also proposed an open-source workflow for computational generation and finite-element analysis of non-woven fibrous materials. To avoid interpenetration of fibers, we generated a micro-mechanical model with curved fibers in Blender, an open-source 3D computer graphics software, and applied rigid-body physics to fibers to repel each other for stacking. We modeled the paper-making process by simulating the falling and shaking of the fibers. Then, we further analyzed the electrical properties of the fibrous network in the open-source Salome-Elmer software. Overall, the proposed open-source workflow facilitates and speeds up the generation and analysis of the non-overlapping fibrous network.

description: The Nation’s 265 dairy cooperatives marketed 122.6 billion pounds of milk, or 82 percent of all milk sold to plants and dealers in 1992. These cooperatives were owned by 110,440 member-producers. Eighty-six cooperatives operated 299 dairy processing and manufacturing plants, 44 cooperatives had milkreceiving stations only, and 135 had no milk-handling facilities. Cooperatives sold 16 percent of the Nation’s packaged fluid products, 10 percent of the ice cream and ice milk, 65 percent of the butter, 81 percent of the dry milk products, 43 percent of the natural cheese, 48 percent of the dry whey products, and 13 percent of the cottage cheese made in the United States. The prevailing method of paying for member milk by the reporting cooperatives was to adjust the milk price for both butterfat and other component(s). Milk quality was the primary driving factor in the overwhelming majority of price incentive programs offered by cooperatives.
