description: We analyse here the role electrons on Anderson-U impurities play in superconductivity in a metal alloy. We find that phonon coupling at impurities counteracts the traditional effects which dominate T_c suppression in the non-magnetic limit. In some cases, we findt hat non-magnetic impurities can enhance T_c. In the Kondo limit, a Fermi liquid analysis reveals that it is the enhancement in the density of states arising from the Kondo resonancethat counteracts pair-weakening.

description: This paper presents a fast and effective computer algebraic method for analyzing and verifying non-linear integer arithmetic circuits using a novel algebraic spectral model. It introduces a concept of algebraic spectrum, a numerical form of polynomial expression; it uses the distribution of coefficients of the monomials to determine the type of arithmetic function under verification. In contrast to previous works, the proof of functional correctness is achieved by computing an algebraic spectrum combined with a local rewriting of word-level polynomials. The speedup is achieved by propagating coefficients through the circuit using And-Inverter Graph (AIG) datastructure. The effectiveness of the method is demonstrated with experiments including standard and Booth multipliers, and other synthesized non-linear arithmetic circuits up to 1024 bits containing over 12 million gates.

Improving the energy resolution of photon counting Microwave Kinetic Inductance Detectors using principal component analysis

description: We develop a photon energy measurement scheme for single photon counting Microwave Kinetic Inductance Detectors (MKIDs) that uses principal component analysis (PCA) to measure the energy of an incident photon from the signal ("photon pulse") generated by the detector. PCA can be used to characterize a photon pulse using an arbitrarily large number of features and therefore PCA-based energy measurement does not rely on the assumption of an energy-independent pulse shape that is made in standard filtering techniques. A PCA-based method for energy measurement is especially useful in applications where the detector is operating near its saturation energy and pulse shape varies strongly with photon energy. It has been shown previously that PCA using two principal components can be used as an energy-measurement scheme. We extend upon these ideas and develop a method for measuring the energies of photons by characterizing their pulse shapes using any number of principal components and any number of calibration energies. Applying this technique with 50 principal components, we show improvements to a previously-reported energy resolution for Thermal Kinetic Inductance Detectors (TKIDs) from 75 eV to 43 eV at 5.9 keV. We also apply this technique with 50 principal components to data from an optical to near-IR MKID and achieve energy resolutions that are consistent with the best results from existing analysis techniques.

description: Magnetospheric ultra-low frequency (ULF) waves contribute to space weather in the solar wind - magnetosphere - ionosphere system. The monitoring of these waves by space- and ground-based instruments, however, produces "big data" which is difficult to navigate, mine and analyse effectively. We present sonification, the process of converting an oscillatory time-series into audible sound, and citizen science, where members of the public contribute to scientific investigations, as a means to potentially help tackle these issues. Magnetometer data in the ULF range at geostationary orbit has been sonified and released to London high schools as part of exploratory projects. While this approach reduces the overall likelihood of useful results from any particular group of citizen scientists compared to typical citizen science projects, it promotes independent learning and problem solving by all participants and can result in a small number of unexpected research outcomes. We present one such example, a case study identified by a group of students -of decreasing-frequency poloidal field line resonances over multiple days found to occur during the recovery phase of a CME-driven geomagnetic storm. Simultaneous plasma density measurements show that the decreasing frequencies were due to the refilling of the plasmasphere following the storm. The waves were likely generated by internal plasma processes. Further exploration of the audio revealed many similar events following other major storms, thus they are much more common than previously thought. We therefore highlight the potential of sonification and exploratory citizen science in addressing some of the challenges facing ULF wave research.

Analysis of forest-plantation dynamics using multi-temporal optical and SAR satellite data in West Kalimantan, Indonesia.
Creators: name: Louis, Valentin
Publisher: name: University of Leicester
Year: 2025

description: This study aims to explore the dynamics of forest and oil palm plantations in West Kalimantan to improve sustainable management practices. Oil palm plantations play an important role in global food security and are expanding continuously in South-East Asia. They often have a significant environmental impact due to habitat fragmentation, biodiversity loss, and deforestation. Understanding the spatial and temporal patterns of these plantations is crucial for better management and reducing environmental impact. To assess forest and plantation dynamics, land cover maps were created using a Random Forest classifier on data from Sentinel-1, Sentinel-2, ALOS PALSAR-2, and Landsat 8 satellites, incorporating elevation and slope data from SRTM. The model achieved an overall accuracy of 80.7%±1% and a Kappa coefficient of 0.76. Time series analysis was performed on LAI and FAPAR derived from MODIS and Sentinel-2. Seasonal FAPAR anomalies revealed distinct wet and dry season patterns. Forests showed greater variability compared to plantations, attributed to the unmanaged nature of forests. Conversely, plantations demonstrated uniform structure and productivity due to consistent management and fertilization practices. Oil palm productivity was analysed in relation to FAPAR, LAI, precipitation, and temperature using an ARIMA model. FAPAR and precipitation showed a weak linear relationship with fresh fruit bunch yield, while LAI had a stronger positive correlation. Maximum temperature exhibited a strong positive relationship with productivity (R² = 0.62). The ARIMA model demonstrated the potential for forecasting productivity fluctuations using satellite and weather data. Overall, this study highlights the complex interplay between human activities and environmental factors in shaping forest and plantation landscapes, providing insights for sustainable management practices. Earth Observation imagery and machine learning models can improve oil palm productivity, resource efficiency, and forest protection.

description: The constraint coordinate-momentum phase space (CPS) formulation of finite-state quantum systems has recently revealed that the triangle window function approach is an isomorphic representation of the exact population-population correlation function of the two-state system. We use the triangle window (TW) function and the CPS mapping kernel element to formulate a novel useful representation of discrete electronic degrees of freedom (DOFs). When it is employed with nonadiabatic field (NaF) dynamics, a new variant of the NaF approach (i.e., NaF-TW) is proposed. Extensive benchmark tests of model systems in both the condensed phase and gas phase demonstrate that the NaF-TW approach is competent in faithfully capturing the dynamical interplay between electronic and nuclear DOFs. In comparison to the symmetrical quasi-classical (SQC) method where triangle window functions were originally proposed, the performance of NaF-TW is significantly better when the bifurcation characteristic of nuclear motion in the asymptotic region is important.

description: We discuss the semi-classical perturbation spectra produced in the massless fields of the low energy string action in a pre big bang type scenario. Axion fields may possess an almost scale-invariant spectrum on large scales dependent upon the evolution of the dilaton and moduli fields to which they are coupled. As an example we calculate the spectra for three axion fields present in a truncated type IIB model and show that they are related with at least one of the fields having a scale-invariant or red perturbation spectrum. In the simplest pre big bang scenario this may be inconsistent with the observed isotropy of the microwave background. More generally, relations between the perturbation spectra in low energy string cosmologies reflect the symmetries of the theory.

Subjects: subject: Methodology (stat.ME)

description: In this contribution we deal with the problem of learning an undirected graph which encodes the conditional dependence relationship between variables of a complex system, given a set of observations of this system. This is a very central problem of modern data analysis and it comes out every time we want to investigate a deeper relationship between random variables, which is different from the classical dependence usually measured by the covariance. In particular, in this contribution we deal with the case of Gaussian Graphical Models (GGMs) for which the system of variables has a multivariate gaussian distribution. We study all the existing techniques for such a problem and propose a smart implementation of the symmetric parallel regression technique which turns out to be very competitive for learning sparse GGMs under high dimensional data regime.

description: We investigate the ground state and quantum dynamics of an interacting bosonic chain with the nonreciprocal hopping. In sharp contrast to its Hermitian counterpart, the ground state can support Mott insulators in systems with noninteger filling due to the competition between nonreciprocal hopping and the on-site interaction. For the quantum dynamics, conservation laws for non-Hermitian systems manifest a stark difference from their Hermitian counterpart. In particular, for any Hermitian operator that commutes with the Hamiltonian operator, its expectation value is guaranteed to be nonconserved in the non-Hermitian quantum dynamics. To systematically identify the non-Hermitian conservation law, we establish a generic approach for constructing the conserved quantities in non-Hermitian many-body quantum systems with completely real spectra, and illustrate it concretely by the system under study. The direct experimental observation of Mott insulators in systems with noninteger filling and non-Hermitian conservation laws can be performed by ultracold atoms in optical lattices with the engineered nonreciprocal hopping.

description: A five-dimensional (5D) generalized Gödel-type manifolds are examined in the light of the equivalence problem techniques, as formulated by Cartan. The necessary and sufficient conditions for local homogeneity of these 5D manifolds are derived. The local equivalence of these homogeneous Riemannian manifolds is studied. It is found that they are characterized by three essential parameters $k$, $m^2$ and $ω$: identical triads $(k, m^2, ω)$ correspond to locally equivalent 5D manifolds. An irreducible set of isometrically nonequivalent 5D locally homogeneous Riemannian generalized Gödel-type metrics are exhibited. A classification of these manifolds based on the essential parameters is presented, and the Killing vector fields as well as the corresponding Lie algebra of each class are determined. It is shown that the generalized Gödel-type 5D manifolds admit maximal group of isometry $G_r$ with $r=7$, $r=9$ or $r=15$ depending on the essential parameters $k$, $m^2$ and $ω$. The breakdown of causality in all these classes of homogeneous Gödel-type manifolds are also examined. It is found that in three out of the six irreducible classes the causality can be violated. The unique generalized Gödel-type solution of the induced matter (IM) field equations is found. The question as to whether the induced matter version of general relativity is an effective therapy for these type of causal anomalies of general relativity is also discussed in connection with a recent article by Romero, Tavakol and Zalaletdinov.

description: We investigate nonlinear structure formation in the fuzzy dark matter (FDM) model using both numerical and perturbative techniques. On the numerical side, we examine the virtues and limitations of a Schrodinger-Poisson solver (wave formulation) versus a fluid dynamics solver (Madelung formulation). We also carry out a perturbative computation of the one-loop mass power spectrum. We find that (1) in many cases, the fluid dynamics solver is capable of producing the expected interference patterns, but it fails where destructive interference causes the density to vanish which generally occurs in the nonlinear regime. (2) The Schrodinger-Poisson solver works well in all test cases, but it is demanding in resolution: one must resolve the small de Broglie scale to obtain the correct dynamics on large scales. (3) We compare the mass power spectrum from perturbation theory against that from the Schrodinger-Poisson solver, and find good agreement in the mildly nonlinear regime. Compared with fluid perturbation theory, wave perturbation theory has a more limited range of validity. (4) As an application, we compare the Lyman-alpha forest flux power spectrum obtained from the Schrodinger-Poisson solver versus one from an N-body simulation (which is often used as an approximate method to make predictions for FDM). At redshift 5, the two, starting from the same initial condition, agree to better than 10 % on observationally relevant scales as long as the FDM mass exceeds $2 \times 10^{-23}$ eV.

description: The impact of spin induced deformation and shape phase transitions on nuclear level density and consequently on neutron emission spectra of the decay of compound nuclear systems 112^Ru to 123^Cs (N = 68 isotones) is investigated in a microscopic framework of Statistical theory of superfluid nuclei. Our calculations are in good accord with experimental data for evaporation residue of 119^Sb^* and 185^Re^* and show a strong correlation between spin induced structural transitions and NLD. We find that the inverse level density parameter K increases with increasing spin for all the systems, but it decreases with a deformation or a shape change that results in the enhancement of level density and emission probability. A sharp shape phase transition from oblate to uncommon prolate non-collective in well deformed nuclei leads to band crossing and enhancement of level density which fades away while approaching sphericity at or near shell closure manifesting shell effects.

description: Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear magnetic resonance (NMR) spectroscopy owing to their micron-scale detection volume and non-inductive based detection. A remaining challenge is to realize sufficiently high spectral resolution and concentration sensitivity for multidimensional NMR analysis of picoliter sample volumes. Here, we address this challenge by spatially separating the polarization and detection phases of the experiment in a microfluidic platform. We realize a spectral resolution of 0.65 +/- 0.05 Hz, an order-of-magnitude improvement over previous diamond NMR studies. We use the platform to perform two-dimensional correlation spectroscopy of liquid analytes within an effective ~20 picoliter detection volume. The use of diamond quantum sensors as in-line microfluidic NMR detectors is a significant step towards applications in mass-limited chemical analysis and single cell biology.

subject: Education

description: This paper is a conceptual analysis in methodology. The purpose it fulfils is that of analysing the critical and dialogic pedagogy of Paulo Freire, to arrive at implications of Freire’s philosophy and approach for the current educational context of the Kingdom of Bahrain. The Bahraini context is currently one of major economic, social, and educational reforms. Despite several reform initiatives, however, schools in Bahrain are still not advancing as they should be and deficiencies continue to exist in students’ development of higher-order thinking skills, such as critical thinking, problem-solving, and analysis. Among the implications made by this study are ones related to: teaching and learning practices within a classroom, cultivation of 21st Century skills, curriculum development and planning, and the role played by the teacher. The paper ends with a number of significant recommendations for teachers and policy-makers, which can enhance education in Bahrain and help it progress faster. These recommendations can also prove to be useful to other parallel contexts regionally and internationally.

description: Timelike and null hypersurfaces in the degenerate space-times in the Ashtekar theory are defined in the light of the degenerate causal structure proposed by Matschull. Using the new definition of null hypersufaces, the conjecture that the "phase boundary" separating the degenerate space-time region from the non-degenerate one in Ashtekar's gravity is always null is proved under certain circumstances.

description: We present an analysis of the astrometric results from Gaia second data release (DR2) to Young Stellar Objects (YSOs) in star-forming regions related to the Gould Belt. These regions are Barnard 59, Lupus 1 to 4, Chamaeleon I and II, $ε$-Chamaeleontis, the Cepheus flare, IC 5146 and Corona Australis. The mean distance to the YSOs in each region are consistent with earlier estimations, though a significant improvement to the final errors was obtained. The mean distances to the star-forming regions were used to fit an ellipsoid of size $(358\pm7)\times(316\pm13)\times(70\pm4)$ pc, and centered at $(X_0,Y_0,Z_0)=(-82\pm15, 39\pm7, -25\pm4)$ pc, consistent with recently determined parameter of the Gould Belt. The mean proper motions were combined with radial velocities from the literature to obtain the three dimensional motion of the star-forming regions, which are consistent with a general expansion of the Gould Belt. We estimate that this expansion is occurring at a velocity of $2.5\pm0.1$ km s$^{-1}$. This is the first time that YSOs motions are used to investigate the kinematic of the Gould Belt. As an interesting side result, we also identified stars with large peculiar velocities.

MOFS: Multimodality Fusion Subtyping
Creators: name: Xu, Hui
Publisher: name: Zenodo
Year: 2025

description: The MOFS (Multimodality Fusion Subtyping) framework is a comprehensive approach for integrating and analyzing multi-layer biological data to achieve clinically relevant disease subtype classification. The core principle of MOFS lies in combining diverse biological modalities—such as genomic, transcriptomic, proteomic, histopathological, and radiological data—into a unified analytical framework. By integrating these heterogeneous data sources, MOFS offers a more holistic and nuanced view of disease biology, enabling the identification of underlying patterns that might be overlooked in single-modality analyses.

Integrating multimodal data reveals causal features that may be obscured in single-modality analyses, offering a more complete understanding of diseases. Multimodal data fusion can be categorized into early, intermediate, and late fusion based on the timing of integration. Intermediate fusion integrates data during clustering, allowing for the identification of multimodal joint clusters, capturing dependencies between different omics layers, and revealing underlying biological mechanisms. Intermediate fusion is generally considered more advanced than both early and late fusion, but it demands more sophisticated integration algorithms.

In the MOFS framework, multiple intermediate fusion strategies are employed based on diverse principles to maximize the interpretative power and reliability of the derived subtypes. Following this, late fusion is applied to combine the results obtained from the different algorithms, culminating in a final, consensus-driven clustering outcome. It is important to note that the framework does not rely on any specific intermediate fusion algorithm. Rather, it evaluates the overall consensus from multiple clustering results, ensuring robustness and reliability.

The MOFS framework represents a powerful tool for disease subtype classification by integrating multiple biological data modalities. Through the integration of intermediate fusion and late fusion strategies, MOFS uncovers novel disease subtypes and mechanisms that may be missed in single-modality approaches. This integrated approach not only enhances the accuracy and robustness of disease classification but also provides deeper insights into disease biology, potentially guiding more personalized diagnostic and therapeutic strategies.
Bursts in the Chaotic Trajectory Lifetimes Preceding the Controlled Periodic Motion

description: The average lifetime ($τ(H)$) it takes for a randomly started trajectory to land in a small region ($H$) on a chaotic attractor is studied. $τ(H)$ is an important issue for controlling chaos. We point out that if the region $H$ is visited by a short periodic orbit, the lifetime $τ(H)$ strongly deviates from the inverse of the naturally invariant measure contained within that region ($μ_N(H)^{-1}$). We introduce the formula that relates $τ(H)/μ_N(H)^{-1}$ to the expanding eigenvalue of the short periodic orbit visiting $H$.

description: In this study, a chair-type asymmetric tripedal low-rigidity robot was designed based on the three-legged chair character in the movie "Suzume" and its gait was generated. Its body structure consists of three legs that are asymmetric to the body, so it cannot be easily balanced. In addition, the actuator is a servo motor that can only feed-forward rotational angle commands and the sensor can only sense the robot's posture quaternion. In such an asymmetric and imperfect body structure, we analyzed how gait is generated in walking and stand-up motions by generating gaits with two different methods: a method using linear completion to connect the postures necessary for the gait discovered through trial and error using the actual robot, and a method using the gait generated by reinforcement learning in the simulator and reflecting it to the actual robot. Both methods were able to generate gait that realized walking and stand-up motions, and interesting gait patterns were observed, which differed depending on the method, and were confirmed on the actual robot.

description: The microscopic origin of metamagnetism and metamagnetic transitions in strongly anisotropic antiferromagnets is investigated within a quantum mechanical theory of correlated electrons. To this end the Hubbard model with staggered magnetization m_st along an easy axis e in a magnetic field H || e is studied both analytically and numerically within the dynamical mean field theory (DMFT). At intermediate couplings the self-consistent DMFT equations, which become exact in the limit of large coordination number, are solved by finite temperature Quantum Monte Carlo techniques. The temperature and magnetic field dependence of the homogeneous and staggered magnetization are calculated and the magnetic phase diagram is constructed. At half filling the metamagnetic transitions are found to change from first order at low temperatures to second order near the N'eel temperature, implying the existence of a multicritical point. Doping with holes or electrons has a strong effect: the system becomes metallic, the electronic compressibility increases and the critical temperatures and fields decrease. These results are related to known properties of insulating metamagnets such as FeBr_2, metallic metamagnets such as UPdGe, and the giant and colossal magnetoresistance found in a number of magnetic bulk systems.

description: We construct super AdS black holes in 2+1 dimensions in terms of Chern Simons gauge theory of N=(1,1) super AdS group coupled to a (super)source. We take the source to be a super AdS state specified by its Casimir invariants. We show that the corresponding space-time is a supermultiplet of AdS space-times related to each other by supersymmetry transformations. We give explicit expressions for the masses and the angular momenta of the black holes in a supermultiplet. With one exception, for N=(1,1) one pair of extremal black holes can be accommodated in such all-black hole supermultiplets. The requirement that the source be a unitary representation leads to a discrete tower of excited states which provide a microscopic model for the super black hole.
