AbstractThe inherent randomness and intermittent nature of wind speed fluctuations pose significant challenges in accurately predicting future wind speeds. To address this complexity, a wind speed prediction model based on a multiscale temporal‐preserving embedding broad learning system (MTPE‐BLS) is proposed. MTPE‐BLS used the localised behaviour of wind speed data, which is simpler to model and analyse than global patterns. Firstly, frequency clustering‐based variational mode decomposition (FC‐VMD) is proposed to deal with the non‐stationary wind speed data into multiple intrinsic mode functions (IMFs). Then, temporal‐preserving embedding (TPE) is proposed to extract the underlying temporal manifold structure from the decomposed IMFs. Finally, the extracted features are mapped into the broad learning system (BLS) to establish an accurate prediction model. Experimental results on two real‐world wind speed datasets demonstrate the best performance of the proposed MTPE‐BLS model compared to that of others. Compared to the original BLS, the MTPE‐BLS achieves significant improvements, reducing the root mean square error (RMSE) and mean absolute error (MAE) by an average of 48.57% and 47.72%, respectively.
Protection of systems containing IBR from asymmetrical ground faults using zero sequence current with hardware implementation on FPGA
Authors: Pannell Jason , Gokaraju Ramakrishna 
Published: December 2024

AbstractThe addition of inverter‐based generation to the power system complicates protective relaying in several ways: the magnitude of the fault current will be altered based upon the location of the fault relative to the inverter‐based resource, and the response to a fault will be different than traditional generation. The relatively low fault current of inverter‐based resources presents difficulties in differentiating faults from increased loads. Additionally negative sequence relays may fail in the presence of IBR's due to the negligible negative sequence current produced by the IBR during a fault. This paper presents a novel method to allow the sensitive sub‐cycle detection, and determination of the relative location, of asymmetrical ground in systems containing inverter‐based resources through phasor analysis of zero sequence current. Least Error Squares Estimation is applied to the fault currents to improve the detection time of these faults, with low computational overheard for hardware implementation. Hardware implementation of the protection scheme on an Intel Cyclone IV‐E FPGA is completed and correct operation of the scheme is verified for the raw samples, as well as five and seven sample LES phasor estimations. Hardware testing is compared to the EMT output to confirm the results.
MDRN: Multi‐domain representation network for unsupervised domain generalization

Published: December 2024

AbstractIn deep neural networks, performance can degrade when test data distributions differ from training data. Unsupervised Domain Generalization (UDG) aims to improve generalization across unseen domains by leveraging multiple source domains without supervision. Traditional methods focus on extracting domain‐invariant features, potentially at the expense of feature space integrity and generalization potential. We presents a Multi‐Domain Representation Network (MDRN) for unsupervised multi‐domain learning. MDRN innovates by disentangling and preserving both domain‐invariant and domain‐specific features through an unsupervised cross‐domain reconstruction task. It employs content encoders for domain‐invariant features and multi‐domain style encoders for domain‐specific characteristics. By merging these features based on domain similarity, MDRN constructs a comprehensive feature space that enhances image reconstruction across domains. Additionally, MDRN integrates domain‐specific classifiers, which learn domain classification and provide weighted fusion of domain‐specific features. This design facilitates effective inter‐domain distance measurement and feature integration. Experiments on PACS and DomainNet show MDRN's superior performance over existing state‐of‐the‐art UDG approaches, highlighting its effectiveness in handling distribution shifts between source and target domains.

AbstractLighting systems using light emitting diode (LED) have drawn significant attention across the world. Nevertheless, to maintain a steady light output, these systems necessitate constant current regulators. This article proposes a buck–boost integrated zero voltage switched full‐bridge LED converter with low current stress. It powers two identical lamps and a lamp of power rating twice the identical lamp. A direct current voltage source, arranged in series, transmits a portion of light power without conversion. A regulated low power output is provided using a complete bridge converter. The semiconductor switches off the full‐bridge converter carry minimal current. This characteristic lowers conduction losses. The suggested converter facilitates dimming operation via on–off control and zero voltage switching, leading to minimal switching losses. Further input voltage of full‐bridge converter is modulated to maintain constant LED lamp current. The detailed steady‐state analysis and implementation of the proposed full‐bridge LED converter with dimming control operation is presented here.
Modelling of differential probing analysis for biomedical dielectric spectroscopy

Published: December 2024

AbstractTranscutaneous microwave dielectric spectroscopy holds promise as a modality for non‐invasive subcutaneous biomarker monitoring, such as blood glucose levels. Experimental studies have demonstrated a strong correlation between blood glucose concentration and blood permittivity using microwave signals. However, the sample volume of interest, blood vessels, is located underneath skin layers where the microwave signal interaction with other surrounding biomaterials is accumulated. Here, a computational study of the proposed method to mitigate the contribution of unwanted tissue and thereby increase the specificity of subcutaneous spectroscopy, using differential probing analysis (DPA), is presented. By exploiting the relationship between the diameter of an open‐ended coaxial probe (OCP) and the size of its protruding electric field, two OCPs with different sizes can sense different volumes beneath the skin. The proposed method computationally subtracts the effect of unwanted tissue, estimated with the smaller probe, from the effective contribution of both blood and unwanted tissue with the larger one. The method is validated by using simulated models and data from the full wave software CST Studio Suite across frequencies ranging from 1 to 10 GHz, achieving errors comparable to state‐of‐the‐art techniques.
Orbital dynamics in galactic potentials under mass transfer
Authors: Illés Eduárd , Jánosi Dániel , Kovács Tamás 
Published: December 2024

Context. Time-dependent potentials are common in galactic systems that undergo significant evolution, interactions, or encounters with other galaxies, or when there are dynamic processes such as star formation and merging events. Recent studies show that an ensemble approach along with the so-called snapshot framework in the theory of dynamical systems provide a powerful tool to analyze the time-dependent dynamics.
Aims. In this work, we aim to explore and quantify the phase space structure and dynamical complexity in time-dependent galactic potentials consisting of multiple components.
Methods. We applied the classical method of Poincaré surface of sections to analyze the phase space structure in a chaotic Hamiltonian system subjected to parameter drift. This, however, makes sense only when the evolution of a large ensemble of initial conditions is followed. Numerical simulations explore the phase space structure of such ensembles while the system undergoes a continuous parameter change. The pair-wise average distance of ensemble members allowed us to define a generalized Lyapunov exponent, which might also be time-dependent, to describe the system stability.
Results. We provide a comprehensive dynamical analysis of the system under circumstances where linear mass transfer occurs between the disk and bulge components of the model.

Published: December 2024

Abstract
In the context of a changing climate and the goal of achieving carbon neutrality by 2050, microalgae, particularly spirulina, are emerging as a versatile and sustainable solution to ensure food security, serving as an alternative protein source for human consumption. Spirulina can absorb carbon dioxide during photosynthesis, grows rapidly, does not require arable land, is cultivated year-round, and is rich in protein as well as other macro- and micronutrients. Spirulina stands out not only for its resilience and adaptability to a range of environmental conditions – including variations in light, temperature, pH, and salinity – but also for its low water requirements, making it a promising option for regions with limited water resources. It can address food security challenges by providing nutritional benefits as a dietary supplement and enhancing animal feed quality. Additionally, it supports sustainable agriculture as a biostimulant, improving crop productivity and soil health while reducing reliance on chemical inputs. Its potential as a raw material across various industries and the exploration of new applications make spirulina an attractive candidate for future research, which should focus on enhanced profitability and large-scale accessibility.
Exactly solvable stochastic spectator

Published: December 2024

Abstract
The stochastic formalism of inflation allows us to describe the scalar-field dynamics in a
non-perturbative way. The correspondence between the diffusion and Schrödinger equations
makes it possible to exhaustively construct analytical solutions in stochastic inflation. Those
exact statistical quantities such as distribution and correlation functions have one-to-one
correspondence to the exactly solvable solutions in non-relativistic quantum mechanics in terms of
classical orthogonal polynomials. A class of such solutions is presented by means of isospectral
Hamiltonians with an underlying symmetry called shape invariance.
Gravitational waves and primordial black holes from axion domain walls in level crossing*
Authors: Li 李 Hai-Jun 海军 , Zhou 周 Yu-Feng 宇峰 
Published: December 2024

Abstract
In this paper, we investigate the nano-Hertz gravitational wave (GW) emission and massive primordial black hole (PBH) formation from the light QCD axion scenario. We consider the axion domain wall formation from the level crossing induced by the mass mixing between the light

QCD axion and axion-like particle. A general mixing case in which the heavy and light mass eigenvalues do not necessarily have to coincide with the axion masses is considered. To form the domain walls, the axions should start to oscillate slightly before the level crossing. The domain walls must annihilate before dominating the Universe to avoid cosmological catastrophe. Then, we focus our attention on the GW emission from the domain wall annihilation and the PBH formation from the domain wall collapse. We show the predicted GW spectra with a peak frequency

and peak amplitude

, which can be tested by future pulsar timing array projects. In addition, during the domain wall annihilation, the closed walls could shrink to the Schwarzschild radius and collapse into the PBH. We find that PBHs in the mass range of

could potentially form in this scenario and account for a small fraction (

) of the cold dark matter.

Abstract
Hybrid MEDIPIX detectors are widely used for a variety of applications including scientific experiments at synchrotrons, X-ray Free-Electron-Lasers (XFEL), or with other radiation sources. For many years, MEDIPIX Application-Specific Integrated Circuits (ASIC) and sensors are usually processed on large wafers using a photolithographic lift-off process in order to deposit interconnects such as indium bumps onto the pixel arrays of ASICs and sensors. After deposition, a wafer is singulated into the individual dies and subsequently sensor chips are connected with read-out MEDIPIX ASICs in a flip-chip process. Sensor and ASIC wafers are very expensive and once a process for the hybridization is chosen, a large number of chips are generated having all the same process parameters. For testing process parameters (e.g. flip-chip bonding) or developing detector prototypes, it is desirable to process smaller batches of single dies with a variety of different process parameters. However, applying photolithography to single die with spin-coated photoresist (PR) across the entire die is not a simple task. Due to the large edge bead of the PR, pixels at the periphery of the die will not be processed perfectly. Here we demonstrate a uniform indium bump deposition onto a 256×257 pixel array (55 μm-pitch) of a MEDIPIX individual die using a mechanical masking method that does not require photolithography. Such method will allow testing and optimizing indium bumps on a variety of MEDIPIX chips without processing a large number of expensive wafers. This masking method for single die is compared to the wafer-scale process of indium bump deposition on MEDIPIX ASICs using photolithography.

Published: December 2024

Abstract
The next decade will see an order of magnitude increase in
data collected by high-energy physics experiments, driven by the
High-Luminosity LHC (HL-LHC). The reconstruction of charged
particle trajectories (tracks) has always been a critical part of
offline data processing pipelines. The complexity of HL-LHC data
will however increasingly mandate track finding in all stages of an
experiment's real-time processing. This paper presents a GNN-based
track-finding pipeline tailored for the Run 3 LHCb experiment's
vertex detector and benchmarks its physics performance and
computational cost against existing classical algorithms on GPU
architectures. A novelty of our work compared to existing GNN
tracking pipelines is batched execution, in which the GPU evaluates
the pipeline on hundreds of events in parallel. We evaluate the
impact of neural-network quantisation on physics and computational
performance, and comment on the outlook for GNN tracking algorithms
for other parts of the LHCb track-finding pipeline.

Abstract
In experiments involving the synthesis of super-heavy elements through heavy ion reactions, it was crucial to precisely adjust the mean energy of the heavy ion beam to identify the narrow peaks of the excitation functions. A motorized manipulator was developed to degrade the heavy ion beam, enabling the adjustment of the mean energy in finer increments and faster than was achievable by the cyclotron alone. Thin metal foils used as ion beam energy degraders were positioned on an aluminum mount with windows. The ion beam traverses these degraders, leading to energy loss, and the final energy can be adjusted to the desired value by varying the effective thickness of the foils. This study includes a calculation of the ion beam energy after energy loss, along with an experimental evaluation of energy loss straggling and a calculation of energy distribution inside the target. The tests carried out revealed that simulations may underestimate beam energy loss straggling, highlighting the importance of experimental measurements of the beam energy distribution for real material dimensions.

Abstract
The construction of the High Intensity heavy-ion Accelerator
Facility (HIAF) is currently underway, with the High Energy FRagment
Separator (HFRS) serving as a critical component. The HFRS, a
next-generation in-flight radioactive separator, is designed to
produce, separate, and purify rare isotopes with a maximum magnetic
rigidity of 25 Tm, facilitating experimental studies on very
short-lived and neutron-rich isotopes. To protect the environment
and equipment, beam dumps are essential for intercepting
high-intensity primary beams with different charge states
post-target. Utilizing the beam optics of the HFRS and beam
parameters after the target, Geant4 ion tracking simulations were
employed to determine the ion trajectories of both primary beam and
secondary beam. The interception efficiency for the primary beam and
the transmission efficiency for the secondary beam were calculated,
providing strategies and movement range for beam dump
utilization. These findings are expected to contribute to the future
operation of the HFRS.
Reading Practices
Authors: Najman Hindy 
Published: December 2024

Abstract
This chapter serves to introduce the book as it considers the ways in which textual traditions emerged and transformed across the Hellenistic period in ancient Judaism. Scholarship has considered this as a period of Sp&gt;ätjudentum, either as a kind of afterthought of Judaism or as an anticipation of the rabbinic movement. In contrast, this book argues that the Hellenistic period was one of radical innovation, deep and complex engagement with the Greek philosophical tradition, and a fundamentally formative period for the history of Judaism. The entangled history and hermeneutics embedded within and beyond the texts of this period elucidate a dynamic conversation of reception, hermeneutics, and innovation. These texts both inherit a past in their reading and draw from their context philosophically, literarily, and theologically; thus, to study vitality within these texts is to practice a philology that is forward-moving, and which participates in new composition, expansion, and poesis. The ongoing growth and expansion of biblical traditions sustains the life of textual traditions through interpretative communities which read and perform the texts. Forward-moving philology embraces pluriformity of texts and diverse manuscript traditions and textual versions as signs of life, continuity, breath, and memory. This interpretive framework counteracts the longstanding tendencies within the discipline of biblical studies to privilege early, originary moments or expressions of ancient Israelite religion and to form a narrative of Judaism borrowing from Greek traditions.
Canonical Expansion and Pluriformity
Authors: Najman Hindy 
Published: December 2024

Abstract
If we are to understand the authority of scriptural traditions and other religiously privileged corpora, we must seek to understand the generative vitality of these texts beyond later boundaries between so-called canonical texts and the marginal texts to which they inevitably give rise. The field has yet to fully integrate the discoveries from the Dead Sea Scrolls and other contemporaneous texts beyond the marginal label into the understanding of an emerging Judaism in the Hellenistic period. The concern with identifying the author function as understood post-Enlightenment has inhibited recognition of texts to which the anonymity of the author is fundamental as well as understanding pseudonymity as participation in an already growing set of ideas and concepts that are associated with a variety of characters. Furthermore, intertextuality as applied within biblical studies has continued to disassemble the text into its pre-texts instead of understanding interactions across textual traditions as a source of life. Moving beyond the divide between models of literary analysis and historical reconstruction, practices of philology must be considered alongside practices of reading through interpretation and composition of new text. The work of the scholar is that of an intervening reader who continues to produce the texts through their own reading. As such, biblical studies and the study of ancient Judaism should never be constrained or exhausted by a single discrete discipline, language, or approach but must seek participation within the humanities at large.
Reading, Fragments, and Selfhood
Authors: Najman Hindy 
Published: December 2024

Abstract
The Jewish literature of the Hellenistic era both exhibits an entanglement between text and self as it both imagines the self and invites the reader to imagine and transform their self upon reading. Just as language continues to grow in dynamic ways, so too the new voices of individuals and communities are manifest through the vitality of new textual traditions. Fundamentally the reader of those textual traditions emerges as the new voice both with respect to reception and to the transformation of the older tradition now in the space of a new tradition. This points to a transformation of the concept of prophecy, not its end, through a dynamic understanding of the self. Just as the prophet looks beyond the here and now, as the self aspires to move beyond one’s framework to another state of being, the self-imagined life beyond one’s own present. The self as reader can aspire towards this perfection through engagement with texts and their fragments. Ethical reading responds to a biblical text’s call for completion by allowing the self to be read by the text and shaped and unshaped through narratives, images, and critical encounters with the traditions of interpretative communities. This call to change is also the call for a vitality which is generative for community and for refining the individual who inherits and transforms herself through the act of reading, in perfectionist tendencies and towards improvement.
