description: Periodic ripples generated from the off-normal incidence ion beam bombardment of solid surfaces have been observed to propagate with a dispersion in the velocity. We investigate this ripple behaviour by means of a Monte Carlo model of the erosion process, in conjuction with one of two different surface diffusion mechanisms, representative of two different classes of materials; one is an Arrhenius-type Monte Carlo method including a term (possibly zero) that accounts for the Schwoebel effect, the other a thermodynamic mechanism without the Schwoebel effect. We find that the behavior of the ripple velocity and wavelength depends on the sputtering timescale, qualitatively consistent with experiments. Futhermore, we observe a strong temperature dependance of the ripple velocity, calling for experiments at different temperatures. Also, we observe that the ripple velocity vanishes ahead of the periodic ripple pattern.

description: We study the Casimir problem for a fermion coupled to a static background field in one space dimension. We examine the relationship between interactions and boundary conditions for the Dirac field. In the limit that the background becomes concentrated at a point (a ``Dirac spike'') and couples strongly, it implements a confining boundary condition. We compute the Casimir energy for a masslike background and show that it is finite for a stepwise continuous background field. However the total Casimir energy diverges for the Dirac spike. The divergence cannot be removed by standard renormalization methods. We compute the Casimir energy density of configurations where the background field consists of one or two sharp spikes and show that the energy density is finite except at the spikes. Finally we define and compute an interaction energy density and the force between two Dirac spikes as a function of the strength and separation of the spikes.

description: The recent development of hybrid systems based on superconducting circuits has opened up the possibility of engineering sensors of quanta of different degrees of freedom. Quantum magnonics, which aims to control and read out quanta of collective spin excitations in magnetically-ordered systems, furthermore provides unique opportunities for advances in both the study of magnetism and the development of quantum technologies. Using a superconducting qubit as a quantum sensor, we report the detection of a single magnon in a millimeter-sized ferromagnetic crystal with a quantum efficiency of up to~$0.71$. The detection is based on the entanglement between a magnetostatic mode and the qubit, followed by a single-shot measurement of the qubit state. This proof-of-principle experiment establishes the single-photon detector counterpart for magnonics.

description: This study estimates the farm-gate breakeven price of switchgrass relative to wheat in Oklahoma. The breakeven price of switchgrass is determined for two situations: when external consequences are ignored and when the environment costs of changes in soil erosion, fertilizer (nitrogen and phosphorous) runoff, and soil organic carbon are considered. Results suggest that the farm-gate breakeven price of switchgrass from the internal cost only perspective is higher than the cost if the value of the selected external consequences is considered. The potential environmental benefits are greater if highly erodible land is switched from annual cropping to switchgrass.

description:
BACKGROUND: Hypertension can have deleterious effects on cognitive function; however, few studies have examined its effects on cognition among Hispanics/Latinos. OBJECTIVE: To assess associations between hypertension status with 1) change in cognitive performance, and 2) having mild cognitive impairment (MCI) among diverse Hispanics/Latinos. METHODS: This population-based, prospective cohort, multisite study included Hispanic/Latino adults aged 45 to 72 years in enrolled in the Hispanic Community Health Study/Study of Latinos at Visit 1 (2008-2011; mean age of 63.40±8.24 years), and the Study of Latinos-Investigation of Neurocognitive Aging at Visit 2 (2016-2018), with a mean follow-up duration of 7 years (n = 6,173). Hypertension status was assessed at both visits: normotension (no hypertension), incident hypertension (only at Visit 2), and persistent hypertension (at both visits). We examined change in cognitive performance and having MCI (only assessed at Visit 2) relative to hypertension status and adjusted for demographics and cardiovascular disease risk factors. RESULTS: Compared to normotension, persistent hypertension was associated with significantly increased decline in verbal fluency (β= -0.08; CI = [-0.16;-0.01]; p < 0.05), and processing speed (β= -0.11; CI = [-0.20;-0.02]; p < 0.05). Incident hypertension was not associated with significant change in cognitive performance. Both incident (OR = 1.70; CI = [1.16;2.50]; p < 0.01) and persistent hypertension (OR = 2.13; CI = [1.57;2.88]; p < 0.001) were associated with significantly higher odds ratios of having MCI. CONCLUSIONS: These findings indicate that persistent hypertension is associated with clinical impairment and domain-specific cognitive decline in middle-aged and older Hispanics/Latinos. It underscores the importance of monitoring blood pressure in routine healthcare visits beginning at midlife in this population to reduce the burden of cognitive decline.

description: The Poisson multi-Bernoulli mixture (PMBM) is a multi-target distribution for which the prediction and update are closed. By applying the random finite set (RFS) framework to multi-target tracking with sets of trajectories as the variable of interest, the PMBM trackers can efficiently estimate the set of target trajectories. This paper derives two trajectory RFS filters for extended target tracking, called extended target PMBM trackers. Compared to the extended target PMBM filter based on sets on targets, explicit track continuity between time steps is provided in the extended target PMBM trackers.

description: The impact parameter and rapidity dependence of the Cronin effect for massless pions in $d+Au$ reactions at $\sqrt{s}_{NN}=200$ GeV at RHIC is computed in the framework of pQCD multiple elastic scattering on a nuclear target. We introduce a formalism to incorporate initial state energy loss in perturbative calculations and take into account the elastic energy loss in addition to the transverse momentum broadening of partons.We argue that the centrality dependence of the Cronin effect can distinguish between different hadron production scenarios at RHIC. Its magnitude and rapidity dependence are shown to carry important experimental information about the properties of cold nuclear matter up to the moderate- and large-$x$ antishadowing/EMC regions.

description: We show that it is possible to embed the 1+1 dimensional reduction of certain spherically symmetric black hole spacetimes into 2+1 Minkowski space. The spacetimes of interest (Schwarzschild de-Sitter, Schwarzschild anti de-Sitter, and Reissner-Nordstrom near the outer horizon) represent a class of metrics whose geometries allow for such embeddings. The embedding diagrams have a dynamic character which allows one to represent the motion of test particles. We also analyze various features of the embedding construction, deriving the general conditions under which our procedure provides a smooth embedding. These conditions also yeild an embedding constant related to the surface gravity of the relevant horizon.
Propagation and Dynamics of Relativistic Jets

description: We investigate the dynamics and morphology of jets propagating into the interstellar medium using 2D relativistic hydrodynamic simulations. The calculations are performed assuming axisymmetric geometry and trace a long propagation of jets. The jets are assumed to be 'light' with the density ratio between the beam to the ambient gas much less than unity. We examine the mechanism for the appearance of vortices at the head of jets in the hot spot. Such vortices are known as a trigger of a deceleration phase which appears after a short phase in which one dimensional analysis is dominant. We find that an oblique shock at the boundary rim near the end of the beam strongly affects the flow structure in and around the hot spot. Weakly shocked gas passed through this oblique shock and becomes a trigger for the generation of vortices. We also find the parameter dependence of these effects for the propagation and dynamics of the jets. The jet with slower propagation velocity is weakly pinched, has large vortices and shows very complex structure at the head of the jets and extended synchrotron emissivity.

Triboelectric charging of insulating materials - understanding, manipulation and application to lunar in-situ resource utilisation
Creators: name: Cruise, Reuben David
Publisher: name: Imperial College London
Year: 2023

description: The lunar surface is covered in a deep layer of generally very fine mineral regolith, presenting both opportunities and challenges for exploration and the utilisation of in-situ resources. The reduction of oxygen from lunar regolith will greatly reduce the cost of space exploration by providing fuel, metals and oxygen for life support. On the other hand, the very fine grain size of the regolith combined with the lunar vacuum lead to the build-up of electrical charge on dust grains and their subsequent adhesion to surfaces. Triboelectric charging is the transfer of charge between two surfaces upon contact. It can lead to unwanted charge build-up and subsequent dust adhesion, or it can be used to manipulate regolith for transport or the separation of oxygen bearing minerals. Triboelectric charging is notoriously difficult to predict due to its dependence on a number of environmental and material properties. This thesis presents a theoretical and experimental study of the saturation of triboelectric charge on insulating particles. A new method of simultaneous triboelectric charging and charge measurement is developed, providing a quick, accurate method for triboelectric charge characterisation. Electrical breakdown of air is identified as the primary saturation mechanism for triboelectric charge on polymer particles, explaining the inverse relationship between particle size and saturation surface charge density. Triboelectric charging is unaffected by humidity below a transition humidity level. This transition humidity level is found to be proportional to particle size. The transition humidity level is not determined by the effect of humidity on the dielectric strength of air and is most likely explained by the formation of electrical double layers on material surfaces, and the dependence of this formation on surface hydrophobicity and curvature. The cumulative electric field of multiple particles charged together can cause electrical breakdown at a smaller charge per particle, explaining the inverse relationship between saturation charge per particle and the number of particles charged together. Triboelectric saturation charge increases significantly in a vacuum where electrical breakdown is absent, however, it is possible to discharge particles almost completely and prevent triboelectric charge build-up by maintaining them in an intermediate low pressure environment. The results in this thesis predict triboelectric charging of insulating particles in both atmospheric and vacuum conditions, and both dry and humid air. They can aid in the design and optimisation of electrostatic dust mitigation methods, and mineral separation technologies for lunar and terrestrial mining processes.

description: This article examines what differentiates "socially responsible" farmers (i.e., those who rank environmental benefits higher than profit, based on a Likert style ranking) from farmers who make decisions based solely on financial criteria. A proportional odds model (POM) is proposed to estimate the factors affecting the degree of social responsibility on the technology adoption. The marginal effects indicate that the participation in agricultural easement programs, the perceived importance of precision farming (PF) in the future, as well as the perceived improvement in environmental quality following the precision technologies’ use, all positively influence the decision to adopt for environmental reasons. In contrast, educational attainment and use of University Publications to acquire information about precision agriculture have a positive impact on adoption based on profit motives. These results suggest that there may be a need for further technical advice and information from Extension focusing on environmental benefits of precision agriculture.

description: Clustering is widely used in unsupervised machine learning to partition a given set of data into non-overlapping groups. Many real-world applications require processing more complex multivariate time series data characterized by more than one dependent variables. A few works in literature reported multivariate classification using Shapelet learning. However, the clustering of multivariate time series signals using Shapelet learning has not explored yet. Shapelet learning is a process of discovering those Shapelets which contain the most informative features of the time series signal. Discovering suitable Shapelets from many candidates Shapelet has been broadly studied for classification and clustering of univariate time series signals. Shapelet learning has shown promising results in the case of univariate time series analysis
China's Goal of Combining Economic Self-Reliance With Its Development: Changing Perspectives and Challenges

description: The attainment of self-reliance (zi li geng sheng) is an important goal for China. However, approaches to achieving it have altered greatly since the People’s Republic was established in 1949. Following the split between China and the Soviet Union in 1960, Mao Zedong claimed that China could achieve this goal by promoting economic self-sufficiency at the national level as well as at subnational levels. This approach resulted in a considerable economic burden for China. While national economic self-sufficiency probably was forced on China by the hostility of foreign nations towards it, subnational self-sufficiency was not. Following the death of Mao Zedong in 1976 and the eventual rise to power of Deng Xiaoping, China’s market reforms began in 1978. With the introduction of the household responsibility system in agriculture, China gave up relying on communes and collectives for its agricultural production. The market reforms began in rural areas but were only slowly extended to urban areas because of some opposition to some politbureau numbers to the market reforms. The process of the market reforms since 1978 is outlined with some attention being given to the political hurdles involved in achieving these reforms. As a result of these reforms, the goal of subnational economic self-sufficiency has well and truly been abandoned and national self-sufficiency is no longer practised. These changes have brought new economic risks for China and the Chinese people. The benefit, however, has been greater economic growth and the enhanced global status of China. While economic self-sufficiency is no longer an over-riding goal for China, one part of zi li geng sheng is still very important for it nationally, namely, to control one’s destiny, that is, to be in charge of one’s own affairs, goals and decision-making.

description: While 2-dimensional quantum systems are known to exhibit non-permutation, braid group statistics, it is widely expected that quantum statistics in 3-dimensions is solely determined by representations of the permutation group. This expectation is false for certain 3-dimensional systems, as was shown by the authors of ref. [1,2,3]. In this work we demonstrate the existence of ``cyclic'', or $Z_n$, {\it non-permutation group} statistics for a system of n > 2 identical, unknotted rings embedded in $R^3$. We make crucial use of a theorem due to Goldsmith in conjunction with the so called Fuchs-Rabinovitch relations for the automorphisms of the free product group on n elements.

description: Consider the case where a programmer has written some part of a program, but has left part of the program (such as a method or a function body) incomplete. The goal is to use the context surrounding the missing code to automatically 'figure out' which of the codes in the database would be useful to the programmer in order to help complete the missing code. The search is 'contextualized' in the sense that the search engine should use clues in the partially-completed code to figure out which database code is most useful. The user should not be required to formulate an explicit query. We cast contextualized code search as a learning problem, where the goal is to learn a distribution function computing the likelihood that each database code completes the program, and propose a neural model for predicting which database code is likely to be most useful. Because it will be prohibitively expensive to apply a neural model to each code in a database of millions or billions of codes at search time, one of our key technical concerns is ensuring a speedy search. We address this by learning a 'reverse encoder' that can be used to reduce the problem of evaluating each database code to computing a convolution of two normal distributions.

description: Stellar rotation plays a key role in stellar activity. The rotation period could be detected through light curve variations caused by starspots. Kepler provides two types of light curves, one is the Pre-search Data Conditioning (PDC) light curves, the other is the Simple Aperture Photometer (SAP) light curves. Compared with the PDC light curves, the SAP light curves keep the long-term trend, relatively suitable for searches of long period signals. However, SAP data are inflicted by some artefacts such as quarterly rolls and instrumental errors, making it difficult to find the physical periods in the SAP light curves. We explore a systematic approach based on the light curve pre-processing, period detection and candidate selection. We also develop a simulated light curve test to estimate our detection limits for the SAP-like LCs. After applying our method to the raw SAP light curves, we found more than 1000 main-sequence stars with the period longer than 30 days, 165 are newly discovered. Considering the potential flaw of the SAP, we also inspect the newly found objects with photometry methods, and most of our periodical signals are confirmed.

description: We investigate a disordered single-walled carbon nanotube (SWCNT) in an effective medium super cell approximation (EMSCA). First type of disorder that we consider is the presence of vacancies. Our results show that the vacancies induce some bound states on their neighbor host sites, leading to the creation of a band around the Fermi energy in the SWCNT average density of states.Second type of disorder considered is a substitutional $B_{cb}N_{cn}C_{1-cb-cn}$ alloy due to it's applications in hetrojunctions. We found that for a fixed boron (nitrogen) concentration, by increasing the nitrogen (boron) concentration the averaged semiconducting gap, $E_{g}$, decreases and at a critical concentration it disappears. A consequence of our results for nano electronic devices is that by changing the boron(nitrogen) concentration, one can make a semiconductor SWCNT with a pre-determined energy gap.

Using a combination of national fisheries market data and the results of an experimental auction, we identify three sources of economic damages to shrimp consumers: (1) higher prices paid by consumers for shrimp in 2010, (2) a loss of utility in the form of substituting consumption of preferred wild-caught Gulf shrimp with less-preferred substitutes, and (3) a loss in utility in the form of stigma attached to wild-caught Gulf shrimp.

description: Authoring site-specific outdoor augmented reality (AR) experiences requires a nuanced understanding of real-world context to create immersive and relevant content. Existing ex-situ authoring tools typically rely on static 3D models to represent spatial information. However, in our formative study (n=25), we identified key limitations of this approach: models are often outdated, incomplete, or insufficient for capturing critical factors such as safety considerations, user flow, and dynamic environmental changes. These issues necessitate frequent on-site visits and additional iterations, making the authoring process more time-consuming and resource-intensive. To mitigate these challenges, we introduce CoCreatAR, an asymmetric collaborative mixed reality authoring system that integrates the flexibility of ex-situ workflows with the immediate contextual awareness of in-situ authoring. We conducted an exploratory study (n=32) comparing CoCreatAR to an asynchronous workflow baseline, finding that it enhances engagement, creativity, and confidence in the authored output while also providing preliminary insights into its impact on task load. We conclude by discussing the implications of our findings for integrating real-world context into site-specific AR authoring systems.

description: Disaggregated memory systems achieve resource utilization efficiency and system scalability by distributing computation and memory resources into distinct pools of nodes. RDMA is an attractive solution to support high-throughput communication between different disaggregated resource pools. However, existing RDMA solutions face a dilemma: one-sided RDMA completely bypasses computation at memory nodes, but its communication takes multiple round trips; two-sided RDMA achieves one-round-trip communication but requires non-trivial computation for index lookups at memory nodes, which violates the principle of disaggregated memory. This work presents Outback, a novel indexing solution for key-value stores with a one-round-trip RDMA-based network that does not incur computation-heavy tasks at memory nodes. Outback is the first to utilize dynamic minimal perfect hashing and separates its index into two components: one memory-efficient and compute-heavy component at compute nodes and the other memory-heavy and compute-efficient component at memory nodes. We implement a prototype of Outback and evaluate its performance in a public cloud. The experimental results show that Outback achieves higher throughput than both the state-of-the-art one-sided RDMA and two-sided RDMA-based in-memory KVS by 1.06-5.03x, due to the unique strength of applying a separated perfect hashing index.

description: We present the first high-resolution spectra for the eclipsing binary V404 Lyr showing $γ$ Dor pulsations, which we use to study its absolute properties. By fitting models to the disentangling spectrum of the primary star, we found that it has an effective temperature of $T_{\rm eff,1}=7,330 \pm 150$ K and a rotational velocity of $v_1\sin$$i=148\pm18$ km s$^{-1}$. The simultaneous analysis of our double-lined radial velocities and the pulsation-subtracted ${\it Kepler}$ data gives us accurate stellar and system parameters of V404 Lyr. The masses, radii, and luminosities are $M_1$ = 2.17$\pm$0.06 M$_\odot$, $R_1$ = 1.91$\pm$0.02 R$_\odot$, and $L_1$ = 9.4$\pm$0.8 L$_\odot$ for the primary, and $M_2$ = 1.42$\pm$0.04 M$_\odot$, $R_2$ = 1.79$\pm$0.02 R$_\odot$, and $L_2$ = 2.9$\pm$0.2 L$_\odot$ for the secondary. The tertiary component orbiting the eclipsing pair has a mass of $M_{\rm 3b}$ = 0.71$\pm$0.15 $M_\odot$ in an orbit of $P_{\rm 3b}$ = 642$\pm$3 days, $e_{\rm 3b}$ = 0.21$\pm$0.04, and $a_{\rm 3b}$ = 509$\pm$2 R$_\odot$. The third light of $l_3=4.1\pm0.2\%$ could be partly attributable to the K-type circumbinary object. By applying a multiple frequency analysis to the eclipse-subtracted light residuals, we detected 45 frequencies with signal to noise amplitude ratios larger than 4.0. Identified as independent pulsation modes, seven frequencies ($f_1-f_6$, $f_9$), their new pulsation constants, and the location in the Hertzsprung-Russell diagram indicate that the pulsating primary is a $γ$ Dor-type variable star.

Weak Supervision for Generating Pixel-Level Annotations in Scene Text Segmentation

description: Providing pixel-level supervisions for scene text segmentation is inherently difficult and costly, so that only few small datasets are available for this task. To face the scarcity of training data, previous approaches based on Convolutional Neural Networks (CNNs) rely on the use of a synthetic dataset for pre-training. However, synthetic data cannot reproduce the complexity and variability of natural images. In this work, we propose to use a weakly supervised learning approach to reduce the domain-shift between synthetic and real data. Leveraging the bounding-box supervision of the COCO-Text and the MLT datasets, we generate weak pixel-level supervisions of real images. In particular, the COCO-Text-Segmentation (COCO_TS) and the MLT-Segmentation (MLT_S) datasets are created and released. These two datasets are used to train a CNN, the Segmentation Multiscale Attention Network (SMANet), which is specifically designed to face some peculiarities of the scene text segmentation task. The SMANet is trained end-to-end on the proposed datasets, and the experiments show that COCO_TS and MLT_S are a valid alternative to synthetic images, allowing to use only a fraction of the training samples and improving significantly the performances.

On the algebraic functional equation of the eigenspaces of mixed signed Selmer groups of elliptic curves with good reduction at primes above $p$

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

description: Let $p$ be an odd prime number, and let $E$ be an elliptic curve defined over a number field which has good reduction at every prime above $p$. Under suitable assumptions, we prove that the $η$-eigenspace and the $\barη$-eigenspace of mixed signed Selmer group of the elliptic curve are pseudo-isomorphic. As a corollary, we show that the $η$-eigenspace is trivial if and only if the $\barη$-eigenspace is trivial. Our results can be thought as a reflection principle which relate an Iwasawa module in a given eigenspace with another Iwasawa module in a "reflected" eigenspace.

LM, live cells (Figs 36–39): The single, large chloroplast is divided into two plates lying one against each valve, connected by a broad column.
LM (Figs 20–35): Valves elliptical to linear-elliptical with ends obtusely rounded. Length 8.0–9.5 µm, breadth 5 µm. Raphe filiform.Axial area very narrow, linear. Central area small. Isolated pore lacking. Striae radiate throughout, 18–20 in 10 µm.
SEM, external view (Fig. 40): The raphe slit is straight with visible sternum. Isolated pore absent. Central raphe ends straight. Terminal raphe ends deflected towards the secondary side of the valve and continue onto mantle. Striae uniseriate or irregularly biseriate near axial area. Annulus structure is not recognizable with striae similar to ones of striae. Areolae present as short slits, 70 in 10 µm of stria length.
SEM, internal view (Figs 41, 42): Raphe slit lying in internal sternum. Central raphe endings straight, terminal ends terminate in evident helictoglossae. Elongated subpolar areolae (about 4, two of which are striae) with warty outgrowths. Internally no hymens or occlusions are observed on the areolae.
 Type: — RUSSIA: Lake Frolikha, N 55027.005 E 109058.649, 26.07.2012, leg. M. Kulikovskiy (IBIW slide no. 80/ B369, holotype designated here (= Fig. 20)), COLO slide 80/B369p is isotype.
 Etymology: —Epithet refers to the type locality.
 Observations: This species is similar to Geissleria acceptata (Hustedt) Lange-Bertalot & Metzeltin (1996: 64) but differs by rather large valves and more elliptical valves (not linear-elliptical). G. acceptata possesses an isolated pore, a structure that is absent in G. frolikhiensis sp. nov. (Novais et al. 2013). Other similar species are absent from Europe or elsewhere (see Lange-Bertalot 2001, Novais et al. 2013). G. irregularis Kulikovskiy, Lange-Bertalot & Metzeltin (2012: 117) from Lake Baikal differs by asymmetrical valves to the apical axis, central area. No similar species are known from Lake Baikal.

description: The fast and accurate prediction of unsteady flow becomes a serious challenge in fluid dynamics, due to the high-dimensional and nonlinear characteristics. A novel hybrid deep neural network (DNN) architecture was designed to capture the unsteady flow spatio-temporal features directly from the high-dimensional unsteady flow fields. The hybrid deep neural network is constituted by the convolutional neural network (CNN), convolutional Long Short Term Memory neural network (ConvLSTM) and deconvolutional neural network (DeCNN). The flow around a cylinder at various Reynolds numbers and the flow around an airfoil at higher Reynolds number are carried out to establish the datasets used to train the networks separately. The trained hybrid DNNs were then tested by the prediction of the flow fields at future occasions. The predicted flow fields using the trained hybrid DNNs are in good agreement with the flow fields calculated directly by the computational fluid dynamic solver.

description: The origin of the knee in the energy spectrum of cosmic rays is an outstanding problem in astroparticle physics. Numerous mechanisms have been proposed to explain the structure in the all-particle spectrum. In the article basic ideas of several models are summarized, including diffusive acceleration of cosmic rays in shock fronts, acceleration via cannonballs, leakage from the Galaxy, interactions with background particles in the interstellar medium, as well as new high-energy interactions in the atmosphere. The calculated energy spectra and mean logarithmic masses are compiled and compared to results from direct and indirect measurements.
