description: Many modern applications of online changepoint detection require the ability to process high-frequency observations, sometimes with limited available computational resources. Online algorithms for detecting a change in mean often involve using a moving window, or specifying the expected size of change. Such choices affect which changes the algorithms have most power to detect. We introduce an algorithm, Functional Online CuSUM (FOCuS), which is equivalent to running these earlier methods simultaneously for all sizes of window, or all possible values for the size of change. Our theoretical results give tight bounds on the expected computational cost per iteration of FOCuS, with this being logarithmic in the number of observations. We show how FOCuS can be applied to a number of different change in mean scenarios, and demonstrate its practical utility through its state-of-the art performance at detecting anomalous behaviour in computer server data.

description: The study on $ρ-ω$ mixing is mainly focused on vector mesons decay with isospin I=1, namely $ρ(ω)\toπ^+π^-$ process. In this paper, we present the study of $ρ-ω$ mixing in $ρ(ω)\toπ^+π^-π^0$ (I=0) using a flavor parameterization model for $J/ψ\to VP$ process. By fitting theoretical frame to PDG data, we obtain the SU(3)-breaking effect parameters $s_V=0.03\pm 0.12,\ s_P=0.17\pm 0.17$ and the $ρ-ω$ mixing polarization operator $Π_{ρω}=0.006\pm 0.011\text{\text{GeV}}^2$. The branching ratios are also renewed when mixing effect is incorporated: $Br(J/ψ\to ωπ^0) = (3.64 \pm 0.37)\times 10^{-4}$, $Br(J/ψ\to ωη) = (1.48 \pm 0.17)\times 10^{-3}$, $Br(J/ψ\to ωη^{\prime}) = (1.55\pm 0.56)\times 10^{-4}$; they are different from the corresponding PDG2012 values by 19%, 15% and 15%, respectively.

description: In the littlest Higgs model with T-parity, the production cross section of the T-odd heavy gauge boson pair $Z_H W_H$ is quite sizable at the LHC. In addition, both the $W_H$ and $Z_H$ bosons have almost exclusively one decay channel into $W A_H$ and $H A_H$ respectively, where the dark matter candidate $A_H$ yields a large missing energy signal. Upon the discovery of the Higgs boson at 125 GeV, we study the discovery sensitivity of the final state $ pp \to b\bar{b} l+\rlap{\,/}{E}_T$ to probe the model at the LHC. We find that the standard model backgrounds are manageable by applying suitable kinematic cuts. The LHC running at $\sqrt{s}=14$ TeV with a 100/fb total luminosity is sensitive to the model if the symmetry breaking scale $f$ is below about 850 GeV.

description: Recent work by Baratin et al. (2021) sheds light on an intriguing pattern that occurs during the training of deep neural networks: some layers align much more with data compared to other layers (where the alignment is defined as the euclidean product of the tangent features matrix and the data labels matrix). The curve of the alignment as a function of layer index (generally) exhibits an ascent-descent pattern where the maximum is reached for some hidden layer. In this work, we provide the first explanation for this phenomenon. We introduce the Equilibrium Hypothesis which connects this alignment pattern to signal propagation in deep neural networks. Our experiments demonstrate an excellent match with the theoretical predictions.

description: Tidal interactions play an important role in many astrophysical systems, but uncertainties regarding the tides of rapidly rotating, centrifugally distorted stars and gaseous planets remain. We have developed a precise method for computing the dynamical, non-dissipative tidal response of rotating planets and stars, based on summation over contributions from normal modes driven by the tidal potential. We calculate the normal modes of isentropic polytropes rotating at up to $\simeq90\%$ of their critical breakup rotation rates, and tabulate fits to mode frequencies and tidal overlap coefficients that can be used to compute the frequency-dependent, non-dissipative tidal response (via potential Love numbers $k_{\ell m}$). Although fundamental modes (f-modes) possess dominant tidal overlap coefficients at (nearly) all rotation rates, we find that the strong coupling of retrograde inertial modes (i-modes) to tesseral ($\ell>|m|$) components of the tidal potential produces resonances that may be relevant to gas giants like Jupiter and Saturn. The coupling of f-modes in rapid rotators to multiple components of both the driving tidal potential and the induced gravitational field also affect the tesseral response, leading to significant deviations from treatments of rotation that neglect centrifugal distortion and high-order corrections. For very rapid rotation rates ($\gtrsim 70\%$ of breakup), mixing between prograde f-modes and i-modes significantly enhances the sectoral ($\ell=|m|$) tidal overlap of the latter. The tidal response of very rapidly rotating, centrifugally distorted planets or stars can also be modified by resonant sectoral f-modes that are secularly unstable via the Chandrasekhar-Friedman-Schutz (CFS) mechanism.

description: Cloaking and illusion has been demonstrated theoretically and experimentally in several research fields. Here we present for the first time an active exterior cloaking device in electrostatics operating in a two-horizontally-layered electroconductive domain, and use the superposition principle to cloak electric potentials. The device uses an additional current source pattern introduced on the interface between two layers to cancel the total electric potential to be measured. Also, we present an active exterior illusion device allowing for detection of a signal pattern corresponding to any arbitrarily chosen current source instead of the existing current source. The performance of the cloaking/illusion devices is demonstrated by three-dimensional models and numerical experiments using synthetic measurements of the electric potential. Sensitivities of numerical results to a noise in measured data and to a size of cloaking devices are analysed. The numerical results show quite reasonable cloaking/illusion performance, which means that a current source can be hidden electrostatically. The developed active cloaking/illusion methodology can be used in subsurface geo-exploration studies, electrical engineering, live sciences, and elsewhere. © 2021, The Author(s).

description: We study the electronic structure of finite armchair graphene nanoribbons using density-functional theory and the Hubbard model, concentrating on the states localized at the zigzag termini. We show that the energy gaps between end-localized states are sensitive to doping, and that in doped systems, the gap between the end-localized states decreases exponentially as a function of the ribbon length. Doping also quenches the antiferromagnetic coupling between the end-localized states leading to a spin-split gap in neutral ribbons. By comparing dI/dV maps calculated using the many-body Hubbard model, its mean-field approximation and density-functional theory, we show that the use of a single-particle description is justified for graphene π states. Furthermore, we study the effect of structural defects in the ribbons on their electronic structure. Defects at one ribbon termini do not significantly modify the electronic states localized at the intact end. This provides further evidence for the interpretation of a multi-peaked structure in a recent scanning tunneling spectroscopy (STS) experiment resulting from inelastic tunneling processes [J. van der Lit et al., Nature Commun., in press (2013)]. Finally, we show that the hydrogen termination at the flake edges leaves identifiable fingerprints on the positive bias side of STS measurements, thus possibly aiding the experimental identification of graphene structures.

description: Placental function is a key determinant of fetal growth and development that can be influenced by maternal and fetal environmental factors. The molecular mechanisms by which the placenta senses and responds to environmental cues are poorly understood. This exploratory study aimed to characterize the effect of birth rank (single vs. twin) and placentome morphologic subtype on expression of genes involved in nutrient transport, angiogenesis, immunity and stress response. Cotyledonary tissue was collected from type A, B and C placentomes from five single and six twin fetuses at 140 days of gestation. GLUT1 and GLUT3 were the most highly expressed genes consistent with the high demand for glucose tosupport fetal growth. Expression of BCKDHβ and IGF-2 was 1.3- and 1.5-fold higher, respectively, and PCYT1A was 3-fold lower in singles compared to twins (P < 0.05) while no other differences in gene expression were observed between birth ranks. Expression of EAAT2 and LAT2 was higher while PCYT1A was lower in A compared to B type cotyledons. Expression of GUCY1B1/3 and IGF-1 was higher while CD98 and LAT2 were lower in type B compared to C cotyledons (P < 0.05). Compared to type C cotyledons, expression of EAAT2, IGF-1, IGF-2, LAT1 was higher, while TEK was lower in type A cotyledons. The effects of birth rank on placental gene expression in this study indicated that placental nutrient transport and/or function differs between single and twin pregnancies in sheep. Differences in gene expression between the placentome subtypes suggests that changes in placentome morphology are associated with shifts in amino acid transport and metabolism, oxidative stress and angiogenesis and/or blood flow. This study highlights that placental gene expression differs in response to birth rank and placentome morphologic subtype which suggests that both maternal and fetal factors may influence placental function in sheep. These associations provide insights into gene pathways for more targeted future investigations as well as potential adaptations to improve placental efficiency to support fetal growth in twin pregnancies.

description: The occurrence of Bacillus cereus in milk from does and ewes was not well documented in Ethiopia in spite of the presence of some reports on the prevalence of the bacteria in the milk from bovine. Similarly, the antimicrobial susceptibility profile of isolates from milk was not well documented. To fill this gap, a cross-sectional study was carried out from November 2015 to March 2016 to estimate the prevalence of B. cereus in milk of farm animals and to assess the in-vitro antimicrobial susceptibility profile of the isolates using commercially available antimicrobial discs. For this purpose, milk samples were collected from 146 lactating animals (91 cows, 24 ewes, 31 does) and examined using standard microbiological procedures. The result of the study revealed that overall prevalence of B. cereus in milk samples from the dairy animals was 29.5%. The prevalence for each species were 30.8%, 29% and 25% in the milk of cows, does and ewes, respectively. The study further indicated the significant association (p < 0.05) of B. cereus with cow’s milk sample which was positive for California Mastitis Test (CMT). Based on B. cereus count, it was found that 48.8% of the milk samples harbored bacterial load above the tolerable limit (>105CFU/ml) for human consumption. The disc diffusion test further indicated that B. cereus isolates showed high resistance to specific antimicrobials such as penicillin (100%), ampicillin (100%), cefoxitin (94.7%) and amoxicillin (89.5%), while 3 (15.8%) of the tested isolates (n=19) exhibited multidrug resistance to five antimicrobials (kanamycin, ampicillin, penicillin, amoxicillin and cefoxitin). From the study it was concluded that higher proportion of milk samples from lactating cows, sheep and goats had high B. cereus load. The resistance of B. cereus to a wide range of antibacterial agents suggested the need to consider effective measures on environmental hygiene and monitor the use of antimicrobials in the treatments of mastitis in dairy animals so that animal health and welfare will be further improved and public health hazards minimized.

description: TEM-cells can be used as a standardized field generator for field probe calibration purposes or electromagnetic compatibility measurements. Because of its practical use as a measurement environment, the electromagnetic behavior over a broad range of frequencies is essential. However, without the understanding of wave reflection, mode-conversion, and attenuation, using such a measurement environment is impractical. In this contribution, we calculate the electromagnetic fields in a longitudinal irregular coaxial TEM-cell. Using a semi-analytical approach, we can determine these wave characteristics. The method is based on the projection of Maxwell's equations onto eigenfunctions. This work's primary objective is to examine the effect of irregular deformed boundaries on the electromagnetic field and the resonance frequencies.

description: Hierarchical forecasting problems arise when time series have a natural group structure, and predictions at multiple levels of aggregation and disaggregation across the groups are needed. In such problems, it is often desired to satisfy the aggregation constraints in a given hierarchy, referred to as hierarchical coherence in the literature. Maintaining coherence while producing accurate forecasts can be a challenging problem, especially in the case of probabilistic forecasting. We present a novel method capable of accurate and coherent probabilistic forecasts for time series when reliable hierarchical information is present. We call it Deep Poisson Mixture Network (DPMN). It relies on the combination of neural networks and a statistical model for the joint distribution of the hierarchical multivariate time series structure. By construction, the model guarantees hierarchical coherence and provides simple rules for aggregation and disaggregation of the predictive distributions. We perform an extensive empirical evaluation comparing the DPMN to other state-of-the-art methods which produce hierarchically coherent probabilistic forecasts on multiple public datasets. Comparing to existing coherent probabilistic models, we obtain a relative improvement in the overall Continuous Ranked Probability Score (CRPS) of 11.8% on Australian domestic tourism data, and 8.1% on the Favorita grocery sales dataset, where time series are grouped with geographical hierarchies or travel intent hierarchies. For San Francisco Bay Area highway traffic, where the series' hierarchical structure is randomly assigned, and their correlations are less informative, our method does not show significant performance differences over statistical baselines.

description: We analyze the output of various state-of-The-Art irradiance models for photovoltaic systems. The models include two sun position algorithms, three types of input data time series, nine diffuse fraction models and five transposition models (for tilted surfaces), resulting in 270 different model chains for the photovoltaic (PV) system simulation. These model chains are applied to 30 locations worldwide and three different module tracking types, totaling in 24,300 simulations. We show that the simulated PV yearly energy output varies between 5% and +8% for fixed mounted PV modules and between 26% and +14% for modules with two-Axis tracking. Model quality varies strongly between locations; sun position algorithms have negligible influence on the simulation results; diffuse fraction models add a lot of variability; and transposition models feature the strongest influence on the simulation results. To highlight the importance of irradiance with high temporal resolution, we present an analysis of the influence of input temporal resolution and simulation models on the inverter clipping losses at varying PV system sizing factors for Lindenberg, Germany. Irradiance in one-minute resolution is essential for accurately calculating inverter clipping losses. © 2017 by the authors. Licensee MDPI, Basel, Switzerland.

description: Sensorineural hearing loss (SNHL) can be overcome by electrical stimulation of spiral ganglion neurons (SGNs) via a cochlear implant (CI). Restricted CI performance results from the spatial gap between the SGNs and the electrode, but the efficacy of CI is also limited by the degeneration of SGNs as one consequence of SHNL. In the healthy cochlea, the survival of SGNs is assured by endogenous neurotrophic support. Several applications of exogenous neurotrophic supply have been shown to reduce SGN degeneration in vitro and in vivo. In the present study, nanoporous silica nanoparticles (NPSNPs), with an approximate diameter of <100 nm, were loaded with the brain-derived neurotrophic factor (BDNF) to test their efficacy as long-term delivery system for neurotrophins. The neurotrophic factor was released constantly from the NPSNPs over a release period of 80 days when the surface of the nanoparticles had been modified with amino groups. Cell culture investigations with NIH3T3 fibroblasts attest a good general cytocompatibility of the NPSNPs. In vitro experiments with SGNs indicate a significantly higher survival rate of SGNs in cell cultures that contained BDNF-loaded nanoparticles compared to the control culture with unloaded NPSNPs (p<0.001). Importantly, also the amounts of BDNF released up to a time period of 39 days increased the survival rate of SGNs. Thus, NPSNPs carrying BDNF are suitable for the treatment of inner ear disease and for the protection and the support of SGNs. Their nanoscale nature and the fact that a direct contact of the nanoparticles and the SGNs is not necessary for neuroprotective effects, should allow for the facile preparation of nanocomposites, e.g., with biocompatible polymers, to install coatings on implants for the realization of implant-based growth factor delivery systems. © 2018 Schmidt et al.

description: The modeling of damage processes in materials constitutes an ill-posed mathematical problem which manifests in mesh-dependent finite element results. The loss of ellipticity of the discrete system of equations is counteracted by regularization schemes of which the gradient enhancement of the strain energy density is often used. In this contribution, we present an extension of the efficient numerical treatment, which has been proposed by Junker et al. in 2019, to materials that are subjected to large deformations. Along with the model derivation, we present a technique for element erosion in the case of severely damaged materials. Efficiency and robustness of our approach is demonstrated by two numerical examples including snapback and springback phenomena. © 2021 The Authors.

description: Recent advances in Federated Learning (FL) have brought large-scale collaborative machine learning opportunities for massively distributed clients with performance and data privacy guarantees. However, most current works focus on the interest of the central controller in FL,and overlook the interests of the FL clients. This may result in unfair treatment of clients that discourages them from actively participating in the learning process and damages the sustainability of the FL ecosystem. Therefore, the topic of ensuring fairness in FL is attracting a great deal of research interest. In recent years, diverse Fairness-Aware FL (FAFL) approaches have been proposed in an effort to achieve fairness in FL from different perspectives. However, there is no comprehensive survey that helps readers gain insight into this interdisciplinary field. This paper aims to provide such a survey. By examining the fundamental and simplifying assumptions, as well as the notions of fairness adopted by existing literature in this field, we propose a taxonomy of FAFL approaches covering major steps in FL, including client selection, optimization, contribution evaluation and incentive distribution. In addition, we discuss the main metrics for experimentally evaluating the performance of FAFL approaches, and suggest promising future research directions towards FAFL.

description: The objective of this study was to analyze the lifetime performance of crossbred dairy cattle in the Central highland of Ethiopia. Birth year records of 502 cows maintained at Holetta Agricultural Research Centre from 1974 through 2015 were used to estimate longevity traits. The fixed effects considered were genetic groups, season of birth, and birth year groups. Least squares mean analyses were performed using general linear model procedure of SAS software, version 9.4. The overall means for total life (TL), herd life (HL), productive life (PL), lifetime milk yield (LTMY), lifetime milk yield per day of total life (LTMYTL), lifetime milk yield per day of herd life (LTMYHL), lifetime milk yield per day of productive day (LTMYPL) and calf crop (LTC) were 3294.6±54.16 days, 2046.2±47.19 days, 1367.8±37.7 days, 9314.14±314.2 kg, 2.71±0.06 kg, 4.45±0.08 kg, 6.56±0.10 kg and 4.5±0.10, respectively. Both genetic group and birth year were found to be the factors that significantly influenced (p < at least 0.05) all studied traits. The study revealed that the first generation 50%, and 75% Friesian x Boran crossbred dairy cows performed better in most of the lifetime traits than Borana and later generations (F2 and F3) which implies that segregation effect can be minimized through upgrading. The result may show that about 438.40 days were wasted without production during calf and heifer growth period compared with an ideal situation (24 to 27 months considered as the cow starts production). In addition, cows spent 90.76 days per calving without milk production unnecessarily. The higher gap between TL and HL and between HL and PL could show that more milk and calf production can be obtained through selection and enhancing heifer rearing and cow management. In conclusion, the first generation 50% and 75% Friesian x Boran crossbred dairy cows had performed better in lifetime traits than Boran and later generations (F2 and F3). This could be associated with a reduction in adaptation potential of up-graded generation and reduction in hybrid vigor and recombination losses in inter se generation. Enhancing the farm husbandry practices and optimizing breeding programs that encompass the lifetime traits are essential to reduce the effect of environmental factors, reduce segregation and further genetic improvement.

description: We address optical amplification properties of quantum nanoparticles of the cadmium selenide/cadmium sulfide (CdSe/CdS) material system with different dimensionality of spatial confinement. CdSe/CdS core/shell quantum dots (QDs), core/shell quantum rods (QRs) and 5 monolayer thick core/crown nanoplatelets (NPLs) at ambient temperature are considered, exhibiting 0D, 1D and 2D spatial confinement dimensionality of the electronic system, respectively. Continuous films of all these nanoparticles are synthesised, and amplified spontaneous emission (ASE) spectra are measured under femtosecond pumping at wavelengths of 400 nm and 800 nm, respectively. The lowest threshold is found for NPLs and the highest for QDs, demonstrating the influence of the rod-like and plate-like CdS structures. To emphasize this effect, ASE is demonstrated also in CdSe/CdS QRs and NPLs under nanosecond pumping at 355 nm in the same material films. The amplification has been achieved without use of any feedback structure, emphazising the efficiency of the antenna effect. The pumping threshold fluences for NPLs and QRs are observed to be similar, but no ASE is observed in QDs up to the damage threshold of the nanoparticle layers. The length variation investigation with nanosecond pumping resulted in the gain coefficients of 29 cm -1 and 37 cm -1 for QRs and NPLs, respectively.

description: The Ising model in the presence of a random field, drawn from the asymmetric and anisotropic trimodal probability distribution $P(h_{i})=p\; δ(h_{i}-h_{0}) + q δ(h_{i}+ λ*h_{0}) + r δ(h_{i})$, is investigated. The partial probabilities $p, q, r$ take on values within the interval $[0,1]$ consistent with the constraint $p+q+r=1$, asymmetric distribution, $h_{i}$ is the random field variable with basic absolute value $h_{0}$ (strength); $λ$ is the competition parameter, which is the ratio between the respective strength of the random magnetic field in the two principal directions $(+z)$ and $(-z)$ and is positive so that the random fields are competing, anisotropic distribution. This probability distribution is an extension of the bimodal one allowing for the existence in the lattice of non magnetic particles or vacant sites. The current random field Ising system displays mainly second order phase transitions, which, for some values of $p, q$ and $h_{0}$, are followed by first order phase transitions joined smoothly by a tricritical point; occasionally, two tricritical points appear implying another second order phase transition. In addition to these points, re-entrant phenomena can be seen for appropriate ranges of the temperature and random field for specific values of $λ$, $p$ and $q$. Using the variational principle, we write down the equilibrium equation for the magnetization and solve it for both phase transitions and at the tricritical point in order to determine the magnetization profile with respect to $h_{0}$, considered as an independent variable in addition to the temperature.

description: Sampling discrepancies between different manufacturers and models of lidar sensors result in inconsistent representations of objects. This leads to performance degradation when 3D detectors trained for one lidar are tested on other types of lidars. Remarkable progress in lidar manufacturing has brought about advances in mechanical, solid-state, and recently, adjustable scan pattern lidars. For the latter, existing works often require fine-tuning the model each time scan patterns are adjusted, which is infeasible. We explicitly deal with the sampling discrepancy by proposing a novel unsupervised multi-target domain adaptation framework, SEE, for transferring the performance of state-of-the-art 3D detectors across both fixed and flexible scan pattern lidars without requiring fine-tuning of models by end-users. Our approach interpolates the underlying geometry and normalizes the scan pattern of objects from different lidars before passing them to the detection network. We demonstrate the effectiveness of SEE on public datasets, achieving state-of-the-art results, and additionally provide quantitative results on a novel high-resolution lidar to prove the industry applications of our framework.

description: We give a cheat sensitive protocol for blind universal quantum computation that is efficient in terms of computational and communication resources: it allows one party to perform an arbitrary computation on a second party's quantum computer without revealing either which computation is performed, or its input and output. The first party's computational capabilities can be extremely limited: she must only be able to create and measure single-qubit superposition states. The second party is not required to use measurement-based quantum computation. The protocol requires the (optimal) exchange of O(J log(N)) single-qubit states, where J is the computational depth and N is the number of qubits needed for the computation.

Bulk material manufacture: the potential impact of digitalisation and provenance systems on materials recirculation

description: Reducing GHG emissions without reducing living standards implies recirculating materials rather than discarding or downcycling them: in particular, the emissions associated with the four major bulk materials (steel, cement, plastics and aluminium) are around two-thirds of the entire industrial emissions. This study examines, through a series of expert interviews, how digitalisation, both through provenance systems and analysis tools for sorting discarded materials, could improve circularity in Europe. It finds that whilst there is a large and sudden interest from construction companies and the automotive sector in using recycled materials due to self-imposed low-carbon targets, almost nothing digital is being developed for recirculating either steel or cement. The exception is Business Information Modelling which could assist building or material reuse in second lives, some 15-40 years into the future. For plastics, on-pack provenance systems could be implemented in the short-term, but this depends on cross-supply chain cooperation which is generally lacking. Only for aluminium is there the prospect of substantial near-term improvement, where the introduction of Laser Induced Breakdown Spectroscopy could greatly reduce the downcycling of wrought aluminium into cast grades, potentially eliminating a forecast surplus of cast aluminium by 2030.

description: The existing threat by criminal (intentional) use of electromagnetic tools is discussed. Reported Intentional Electromagnetic Interference (IEMI) attacks and similar incidents will be analyzed and discussed in regard to aspects like motivation and technical skills of the culprits, characteristics of the generated IEMI environment as well as effects on the target systems. Concluding common characteristics will lead to a discussion of the technological challenge of recognition and identification of an IEMI attack as well as backtracking of observed malfunction and destructions to an external IEMI environment.
