description: This work introduces a novel block bootstrap method for time series with multiple periodically correlated (MPC) components called the Variable Multiple Bandpass Periodic Block Bootstrap (VMBPBB). While past methodological advancements permitted bootstrapping time series to preserve certain correlations, and then periodically correlated (PC) structures, there does not appear to be adequate or efficient methods to bootstrap estimate the sampling distribution of estimators for MPC time series. Current methods that preserve the PC correlation structure resample the original time series, selecting block size to preserve one PC component frequency while simultaneously and unnecessarily resampling all frequencies. This destroys PC components at other frequencies. VMBPBB uses bandpass filters to separate each PC component, creating a set of PC component time series each composed principally of one component. VMBPBB then resamples each PC component time series, not the original MPC time series, with the respective block size preserving the correlation structure of each PC component. Finally, VMBPBB aggregates the PC component bootstraps to form a bootstrap of the MPC time series, successfully preserving all correlations. A simulation study across a wide range of different MPC component frequencies and signal-to-noise ratios is presented and reveals that VMBPBB almost universally outperforms existing methods that fail to bandpass filter the MPC time series.

description: This paper presents the results of the latest calibrations of the CLUES model for each of total nitrogen, total phosphorus and Escherichia coli. CLUES has been calibrated nationally against loads estimated from data collected from water quality monitoring stations located across the country which could lead to parameter bias. To ascertain whether there is any systematic bias, the calibration residuals were evaluated against regional (geographical) location and a range of upstream catchment characteristics. We found that CLUES gives reasonable load estimates at the catchment. However, there was significant uncertainty in the parameterisation. While several significant relationships were found between upstream catchment characteristics and the model residuals, these relationships were weak and are unlikely to point to any systematic bias in the calibration.

description: Energy is one of the most important factors for a developing country like Bangladesh. Like the rest of thecountries of the world, the demand for energy is increasing day by day in our country. Energy sector ofBangladesh is exceedingly depended on the limited gas reserve. Given the rising demand for fuel it will bevery difficult t to meat this demand with only indigenous natural gas. About 80% of the power generation inthe country is now gas based. Therefore diversification of fuel has become indispensible it has beenenvision 2021 that 53% of the power generation will be coal based by year 2021. The worldwide scenarioshows that, Coal is the ultimate fuel for future. Bangladesh is very lucky that it has got significant butalmost untapped high quality coal resource. Five coal fields in the country contain 3.3 billion metric tonscoal. Recently rate of coal production from Barapukuria are increased significantly due to application ofmodern coal extracting method, LTCC. Coal to Synthesis gas conversion, is an emerging technology towide the application area of coal and commercially proved technology worldwide. The paper gives anoverview of the current state of coal scenario and natural gas scenario in Bangladesh. Here we discuss theprinciples of coal to syngas conversion technology and aside from a brief introduction to 5 processmethods for conversion of coal to Synthesis Natural Gas (SNG). The Steam-Oxygen Gasification,Hydrogasification, Catalytic Steam Gasification, Underground Steam-Oxygen Gasification, UndergroundHydrogasification processes are discussed with the help of process flow diagram. This paper alsosummaries the present scenario of Syngas production worldwide. Finally we propose a coal based syngasinfrastructure, where coal is converted to syngas, then processed to make Synthesis Natural Gas (SNG),then it transmitted via dedicated pipeline or injected into existing natural gas pipeline to the different typesof user like Household, Thermal Power Plant, Brick Field, Ceramics & Glass Industry and any kind ofthermal process industry. This proposed technology is design to reduce the dependency on natural gas.

description: Knowing the location where groundwater denitrification occurs, or by proxy the groundwater redox status (oxic, mixed, and anoxic), is valuable information for assessing and managing potential agricultural land-use impacts on freshwater quality. We compare the efficacy of supervised and unsupervised learning-based methods to predict groundwater redox status in the agriculturally dominated Tasman, Waikato, and Wellington regions of New Zealand. Overall, the supervised methods demonstrate a prediction bias toward oxic conditions and inability to perform statistically well when using independent regional data. By contrast, the unsupervised method performs statistically well when predicting oxic, mixed, and anoxic conditions and corresponding depths when using independent regional data. The unsupervised learning method provides added benefits.

description: Undocumented or unregistered immigrants are part of European society, particularly in Belgium. However, adequate and reliable data on this population is scarce as it is not always easy for data-collecting authorities to have access to and gather information on them. In this report, we estimate the number of undocumented migrants from Sub-Saharan and North Africa in Belgium based on mortality data from the Belgian statistical office.

We first discuss the how mortality data has been used to study migrant populations and present a brief overview of existing knowledge on undocumented migrants in Belgium. We then look at mortality among regular or registered migrant populations in Belgium. In the last section, we extrapolate the number of undocumented migrants for the chosen regions.

The report focusses on North African and Sub-Saharan African migrants as they constitute the largest undocumented population in Belgium. As per our estimation, the Sub-Saharan non-registered presence, including occasional visitors and visa-holders amounted to about 27,500 individuals if it was counted on a random day between 2012 and 2016. For North Africans during the same period, the numbers amount to about 50,000. This would mean that over 1 in 3 North African nationals encountered in Belgium would not be a registered resident.

In sum, we estimate the total number of non-registered inhabitants of Sub-Saharan African and North-African origin living in Belgium between 2012 and 2016 around 80,000 people. This is less than 1% of the total population of Belgium.

description: A hydrological framework encompassing nitrogen (N), phosphorus (P) and microbial (E. coli) transfer from land to water was developed to provide a consistent and rapid approach for assessing the potential impacts of land activity on water quality in New Zealand. Application of the framework in four catchments highlighted the importance of local catchment knowledge of dominant hydrological processes that was needed to ensure flow partitions derived were a realistic representation of transport processes. Additional refinements are needed to improve process representation (e.g. effects of groundwater lags) and ensure input data (e.g. soil attributes) have appropriate resolution to describe hydrological pathways. We contend that such a framework would provide a consistent and relatively rapid approach for identifying contaminant transfer pathways from land to water that can inform assessments of the potential consequences of land use change and intensification.

description: This grid-based sediment tracing technique improves the precision of source contribution estimates and enhances the granularity of sediment source maps. We test the proposed technique using source and suspended sediment samples collected from the Emu Creek Catchment (911 km2), south-east Queensland, Australia. Geochemical tracers were employed to distinguish sediments derived from the heterogenous and complex underlying rock types. Importantly, the proposed technique provided a greater spatial resolution of the sediment sources by assigning sediment contributions into grid sources rather than the area-specific source types.

description: We explore the effects of driving a cavity at a large photon number in a circuit-QED experiment where the ``matter-like'' part corresponds to an unique Andreev level in a superconducting weak link. The three many-body states of the weak link, corresponding to the occupation of the Andreev level by 0, 1 or 2 quasiparticles, lead to different cavity frequency shifts. We show how the non-linearity inherited by the cavity from its coupling to the weak link affects the state discrimination and the photon number calibration. Both effects require treating the evolution of the driven system beyond the dispersive limit. In addition, we observe how transition rates between the circuit states (quantum and parity jumps) are affected by the microwave power, and compare the measurements with a theory accounting for the ``dressing'' of the Andreev states by the cavity.

description: Social media, self-driving cars, and traffic cameras produce video streams at large scales and cheap cost. However, storing and querying video at such scales is prohibitively expensive. We propose to treat large-scale video analytics as a data warehousing problem: Video is a format that is easy to produce but needs to be transformed into an application-specific format that is easy to query. Analogously, we define the problem of Video Extract-Transform-Load (V-ETL). V-ETL systems need to reduce the cost of running a user-defined V-ETL job while also giving throughput guarantees to keep up with the rate at which data is produced. We find that no current system sufficiently fulfills both needs and therefore propose Skyscraper, a system tailored to V-ETL. Skyscraper can execute arbitrary video ingestion pipelines and adaptively tunes them to reduce cost at minimal or no quality degradation, e.g., by adjusting sampling rates and resolutions to the ingested content. Skyscraper can hereby be provisioned with cheap on-premises compute and uses a combination of buffering and cloud bursting to deal with peaks in workload caused by expensive processing configurations. In our experiments, we find that Skyscraper significantly reduces the cost of V-ETL ingestion compared to adaptions of current SOTA systems, while at the same time giving robustness guarantees that these systems are lacking.

description: We quantify the effect of starspots for the orbital elements of the spotted RS CVn binary $λ$ Andromedae ($λ$ And) and present an empirical correction. The aim is to obtain a more precise orbital solution that can be used to better study the system's severe orbital-rotational asynchronism. Phase-resolved high-resolution optical spectra were recorded over the course of 522 days in 2021-2022. We employed two facilities with medium and high resolution spectroscopy for the multiple activity analyses. Doppler imaging is used to reconstruct $λ$ And's starspots with a high resolution (R= 250 000) and high signal-to-noise ratio spectra. Optimized cross-correlation functions were used to measure precise radial velocities at a level of a few ten's of m/s. The spot-corrected radial velocities enable, on average, a threefold increase in precision of the individual orbital elements. The residual velocity jitter with a full range of 500 m/s is modulated by the rotation period of $λ$ And of 54.4$\pm$0.3 days. Our logarithmic gravity from spectrum synthesis of 2.8$\pm$0.2 together with the interferometrically determined stellar radius suggest a most-likely mass of the primary of $\approx$1.4 Msun. The small orbital mass function then implies a secondary mass of just $\approx$0.1 Msun, which is appropriate for an L-class brown dwarf. The Doppler image reconstructs a dominating cool spot with an umbral temperature difference of $\approx$1000 K with respect to the photosphere of 4660 K and is likely surrounded by a moat-like velocity field. Three more weaker spots add to the total surface spottedness, which is up to 25% of the visible surface. Seven optical chromospheric tracers show rotational modulation of their emission line fluxes in phase with the cool spots. This surface configuration appears to have been stable for the 522 days of our observations.

description: Knowledge of groundwater recharge potential is required for sustainable groundwater management, including the assessment of vulnerability to contamination. This study maps (at 500m x 500m resolution) the potential groundwater recharge zones across New Zealand using national data sets of lithology, slope, aspect, land use, soil drainage and drainage density. Weights to the factor was calculated by three different methods. Five potential groundwater recharge zones were defined across New Zealand. The maps can be used to identify areas of high nutrient leaching in zones where high groundwater recharge potential exists (regions with large lakes and in the lower elevation plains).

description: Assessing the effectiveness of mitigation measures for reducing contaminant losses to water from pastoral farming systems is a challenging task. Two important factors that contribute to this challenge are (i) the considerable spatial variability in landscape vulnerabilities to contaminant loss and (ii) differing land use pressures created by contrasting land management practices that are employed on farms. An approach is described that benchmarks nitrogen (N), phosphorus (P) and sediment discharges for representative dairy and sheep-beef farming types (hereafter referred to as 'typologies') that differ according to inherent landscape vulnerability features or land use pressures created by some key management practices. Landscape vulnerabilities can be defined as the soil, topography and climate factors that are known to influence the inherent risk of contaminant transport to water, whereas land use pressures reflect the diverse set of farm inputs and feed, stock and soil management practices that determine contaminant sources. The analysis was constructed using land use pressure information for the year 2015 contained within Dairybase records held by DairyNZ and farm class surveys reported by Beef + Lamb NZ. Published information sources and expert opinion from rural professionals were also used to define land use pressures for typologies in 1995.

description: We propose a realistic semiconductor system containing bound states in the continuum (BICs) which allows for a practical realization. By varying the confinement strength of excitons in cuprous oxide quantum wells, we show that long-lived Rydberg states of the confined electron-hole pairs appear in the continuum background. The accuracy of calculations of the linewidths based on the coupled-channel Schrödinger equation with three channels and only few basis states is confirmed by a numerically exact solution employing a B-spline basis and the complex coordinate-rotation method. We argue that finite-sized cuprous oxide crystals, due to their large exciton binding energies, are a convenient platform for experimental identification of BICs.

"Why Stars Burn Out"
Creators: name: Wilcox, Clyde Jermaine
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Astrophysics

description: “Why Stars Burn Out: An Electromagnetic Collapse Framework” by Clyde Jermaine Wilcox offers a groundbreaking redefinition of stellar death, replacing the classic thermonuclear exhaustion model with a theory grounded in magnetic field coherence. This paper introduces the concept of Magnetic Information Density (MID) and defines a critical threshold—B_crit—below which stars collapse due to electromagnetic disintegration rather than fuel depletion.

 

Featuring the Wilcox Field Tensor (W_μν) as a novel mathematical tool to capture internal electromagnetic structure, the work explains phenomena such as hydrogen retention in white dwarfs and magnetar cooling anomalies. This framework establishes a new phase diagram for stellar stability and offers testable predictions that challenge conventional mass-based stellar evolution models.

 

This is Version 1, aimed at mainstream astrophysics audiences, with emphasis on observable anomalies and predictive clarity. Future versions will expand into field unification and quantum-boundary implications.

As a model of dark matter we choose the one, in which Maxwell field is coupled to the additional $U(1)$-gauge field envisaging the dark sector, the so-called dark photon model. Magnetization of a black hole also stems from Maxwell-dark photon electrodynamics. One found the radiation power and energy loss of the particle and looked for the imprints of dark matter on those phenomena.

description: In New Zealand the primary sector together with central and local government agencies have been promoting measures to mitigate the adverse effect of farming practices on water quality over the last few decades. We assessed the effectiveness of some key measures such as stock exclusion, riparian protection, and nutrient and effluent management on reducing losses of nitrogen (N), phosphorus (P) and sediment to water. Our aim was to determine how much progress has been made in decreasing contaminant discharges between 1995 and 2015 and to determine what the loads would have been if no mitigation had occurred. To do this we estimated losses from 37 dairy and non-dairy/sheep/beef farm typologies that captured the main attributes of production and contaminant loss pathways, nationally. We also accounted for the rate of uptake of measures. Our findings indicated that while the implementation of these measures has helped to reduce P losses (an estimated 20%-25% reduction) to water, they have not been sufficient to off-set estimated increases in N losses (25%) due to expansion of dairy land over the same period. National sediment load is estimated to have decreased (29%) because of afforestation and other soil conservation works.

description: This research studies the impact of high-quality training datasets on the performance of Convolutional Neural Networks (CNNs) in detecting strong gravitational lenses. We stress the importance of data diversity and representativeness, demonstrating how variations in sample populations influence CNN performance. In addition to the quality of training data, our results highlight the effectiveness of various techniques, such as data augmentation and ensemble learning, in reducing false positives while maintaining model completeness at an acceptable level. This enhances the robustness of gravitational lens detection models and advancing capabilities in this field. Our experiments, employing variations of DenseNet and EfficientNet, achieved a best false positive rate (FP rate) of $10^{-4}$, while successfully identifying over 88 per cent of genuine gravitational lenses in the test dataset. This represents an 11-fold reduction in the FP rate compared to the original training dataset. Notably, this substantial enhancement in the FP rate is accompanied by only a 2.3 per cent decrease in the number of true positive samples. Validated on the KiDS dataset, our findings offer insights applicable to ongoing missions, like Euclid.

description: To meet the water quality outcomes sought by catchment communities and regulators, the losses of nitrogen (N), phosphorus (P) and sediment from dairy and sheep/beef farms must be reduced across many catchments. We conducted a high-level desktop analysis of farm typologies and established that if mitigation actions were fully implemented across dairy and sheep/beef farms, losses of N and P could have been decreased by up to 16 and 23%, respectively, compared to the estimated losses for 2015 (where established actions were only partially implemented). Potential decreases were greater for dairy land (34% N and 26% P) because of its greater per hectare yield and number of mitigation actions available before land use change is required. If established and developing mitigation actions were fully implemented by 2035, potential N, P and sediment losses may decrease by up to 34, 39 and 66%, respectively, compared to actual 2015 losses. These results can inform investment and planning by the rural sector as part of an assessment of the potential for on-farm actions to mitigate losses from existing land use.

description: This work studies the influence of scalar dark matter on the structural properties of strange quark stars (SQS) within a one-fluid framework, considering Yukawa interactions between dark matter and quark matter. Contributions from perturbative QCD, Yukawa interaction between scalar dark matter and quarks, and Bose-Einstein condensation of dark matter are included in the model. We first determine the allowable range of Yukawa interaction coupling by imposing the stability condition for strange quark matter (SQM). Using this range, we derive the equation of state (EOS) for different fractions of dark matter within the total pressure of SQS. These fractions are constrained by the tidal deformability limit from GW170817. The presence of dark matter alters the EOS, leading to changes in the mass-radius relationship, tidal deformability, and stability of SQS. We demonstrate that increasing the mass of dark matter softens the EOS, whereas higher fractions of dark matter lead to stiffer EOSs. We also explore the reasons behind this behavior. Our EOSs not only describe massive objects, such as PSR J0952-0607 and PSR J2215+5135, but also satisfy the tidal deformability constraint from GW170817. These results reveal that incorporating dark matter modifies the EOS, enabling the support of higher stellar masses while maintaining consistency with observational data.

description: Different methods for parameterizing soil hydraulic models can lead to substantially varied predictions of soil-plant-atmosphere water fluxes. This study investigated, for a heterogeneous stony soil, 4 methods of soil hydraulic parameterization. Soil drainage, volumetric water content, and evapotranspiration were modeled using HYDRUS-1D for an irrigated pasture in New Zealand. While all methods underpredicted evapotranspiration by 18% to 30% compared with eddy covariance, improvement in drainage estimates with inverse estimation from field data led to decreased capability for modeling evapotranspiration. We suggest this approach for application in other settings to select the most appropriate parameterization approach for a given soil hydraulic model application.

description: BaseFlow Index (BFI) was determined for all river reaches in New Zealand. A recursive digital filtering technique was applied to 482 gauged sites across New Zealand, then an individual filter parameter was determined for each catchment. BFI varies between 0.20 and 0.96 with an average of 0.53, which indicates 53% of long-term streamflow in New Zealand is likely to originate from groundwater discharge and other delayed sources. This dataset can support water resources planning and management in New Zealand, in particular water supply, stream ecology and pollution risk. The methodology is applicable to any region around the world.

description: In this report, we provide a cross-country comparison of news media consumption patterns and perceived threat in six European countries: Belgium, Germany, Hungary, Italy, Spain, and Sweden (N=9,079). Data were collected among adults aged 25 to 65 through an online survey fielded during three weeks in May and June 2021. Our findings show that newspaper and digital news consumption is clearly lower than television consumption, in all countries. Furthermore, Belgian, German, and Italian respondents hold relatively similar television news consumption patterns (high public service media exposure, lower commercial), but this is quite different among Hungarian and Spanish respondents. They consume more news on commercial outlets. As for newspaper and digital news, Germans and Italians mostly consume quality (or broadsheet) newspapers or digital news, while respondents from other countries report higher consumption of popular (or tabloid) newspapers or digital news. Linking the effects of this media consumption to threat perceptions, results show that exposure to news on public service networks, local television networks, quality newspapers, and quality digital news outlets is linked with lower threat perceptions outgroups. Based on earlier findings regarding the rather neutral narratives of migration on several of these media outlets, this was in line with our expectations. However, consumption of popular newspapers and news websites was also linked with lower threat, albeit to a lesser extent. Consuming television news on commercial networks was linked with greater threat perceptions.

description: We study a class of scalar field models coupled to impurities in arbitrary spacetime dimensions. The system admits the introduction of a second-order tensor that can be forced to obey an equality, if a first-order differential equation is satisfied, compatible with the equation of motion when the potential engenders a very specific form. In the case of static solutions, the energy density of the system can equal the divergence of an auxiliary vector function, which is included to help us solve the model. Stability of the field configuration under rescale of argument is investigated, and the procedure is illustrated considering distinct canonical models. The results show that exact solutions can be obtained in arbitrary dimensions, related to the presence of the first-order equation.

description: We compared the variability of E. coli concentrations in baseflow of 3 different-sized rivers in both summer and winter at the time scales of minutes, hours, and days, to variability from laboratory replication of the measurement methods. Estimates of variability, analysed using the coefficient of variation (CV), were approximately 32% and 60% at hourly and daily time scales. There is strong evidence that both time scale (p < 0.001) and river (p < 0.001) significantly affect the variation in E. coli concentrations. This variability should be considered when interpreting the results from a one-off grab sample used to compare against water quality standards or for calibrating models.

description: In the KIT storage ring KARA (Karlsruhe Research Accelerator), two parallel plates with periodic rectangular corrugations are planned to be installed. These plates will be used for impedance manipulation to study and eventually control the electron beam dynamics and the emitted coherent synchrotron radiation (CSR). In this contribution, we present simulation results showing the influence of different corrugated structures on the longitudinal beam dynamics and how this influence depends on the machine settings in the low momentum compaction regime, which are related to the bunch length changes.

description: Cadmium (Cd) is a non-essential trace element that accumulates in agricultural soils through the application of Cd-rich phosphate fertiliser. Vegetables can accumulate Cd to concentrations that sometimes exceed food safety standards. We investigated the potential of low-cost soil amendments to reduce Cd uptake by spinach, lettuce and onion. Lignite and compost had the greatest ability to sorb Cd and were subsequently selected for pot trials. The addition of 2.5% (dry w/w) municipal compost reduced the Cd concentration in onions, spinach and lettuce by up to 60% in both soils. The addition of lignite gave variable results. This Cd immobilisation was offset by soil acidification caused by the lignite. The results indicate that municipal compost is a low-cost soil conditioner that is effective in reducing plant Cd uptake.

description: There is concern about the deteriorating nutrient status of aquatic receiving environments in New Zealand. We estimated the amount by which current nitrogen (N) concentrations and loads exceed criteria in rivers, lakes and estuaries nationally. Criteria corresponded to national 'bottom-line' (i.e. minimal) environmental objectives set by government policy. Three metrics were evaluated: (1) degree of compliance describes the current TN loads in receiving environments relative to criteria; (2) catchment N status describes the acceptability of catchment N loads compared to criteria; and (3) excess load indicates the amount by which the N load exceeds the maximum allowable load (kg yr‚àí1). Non-compliance with N criteria was broadly distributed nationally particularly in low-elevation catchments.
Catchments with unacceptable N status constituted at least 31% of New Zealand's land area, which corresponds to at least 43% of the country's agricultural land. The national excess load was estimated to be at least 19.1 Gg yr‚àí1. We are 97.5% confident that estimated excess loads exceed zero for nine of 15 regions and for the nation as a whole. The analyses provide a strategic assessment of where reductions in N emissions are required to achieve the minimal national objectives.
