Probing dark energy using anisotropies in the clustering of post-EoR H i distribution
Authors: Dash Chandrachud B.V. , Sarkar Tapomoy Guha 
Published: January 2025

Abstract
We propose an anisotropy quantifier of the H i 21-cm signal traditionally used to clock the astrophysics of the reionization era as a post-reionization dark energy diagnostic. We find that the anisotropy probe can be measured at SNR ∼ 10 in both auto-correlation and in cross-correlation with the Ly-α forest over a wide z and k-range. We propose to use the BAO signature on the anisotropy signal to measure ( H(z), DA
(z)). Subsequently, we put constraints on a dark energy model involving a negative cosmological constant on top of a quintessence scalar field and find that such a model is consistent with futuristic observations.
Probing dark relativistic species and their interactions with dark matter through CMB and 21 cm surveys
Authors: Plombat Hugo , Simon Théo , Flitter Jordan , Poulin Vivian 
Published: January 2025

Abstract
We investigate the sensitivity of the 21 cm power spectrum from cosmic dawn and the epoch of reionization to models of free-streaming dark radiation (parameterized through N
eff) and interacting dark radiation-dark matter models (DM-DR). The latter models have gained attention for their potential in addressing recent cosmological tensions and structure formation challenges.
We perform a Fisher matrix analysis under different assumptions regarding the astrophysical modeling, and forecast the sensitivity of HERA observations, combined with CMB data from Planck and the Simons Observatory (SO), to N
eff and DM-DR interaction modeled using the ETHOS framework assuming a constant scattering rate between the two components.
Most importantly, we find that 21 cm observations can improve the sensitivity to the DM-DR interaction rate by up to four order of magnitude compared to Planck and SO. Conversely, in the limit of low interaction rate (which asymptotically matches N
eff), CMB data dominates the constraining power, but the inclusion of HERA data can provide a ∼ 20% improvement in sensitivity over CMB data alone.
Moreover, we find that HERA observations will be able to probe a region of the DM-DR interaction parameter space which is promising to explain the weak lensing amplitude `S
8' tension. Our results demonstrate the complementarity of 21 cm and CMB data in exploring dark sector interactions.
Analytic results in aligned axion inflation
Authors: Greco Federico , Peloso Marco 
Published: January 2025

Abstract
The original model of axion natural inflation produces a tensor-to-scalar ratio above the
experimental limit. Aligned axion inflation admits inflationary trajectories that originate near a
saddle point of the two-field potential, and terminate due to the instability of the orthogonal
direction. The phenomenology of these solutions is within the current constraints, and a range of
parameters will be probed by the next stage CMB experiments. We provide the analytic solution for
these trajectories and very compact analytic expressions for the associated phenomenology. For
parameters leading to the observed value for the scalar spectral tilt the extension of the
inflationary trajectory is sub-Planckian. However, one eigenvalue of the axion kinetic matrix (in
the basis that diagonalizes the potential) is trans-Planckian. Finally, we discuss the
post-inflationary evolution after the instability. In some cases, the fields reach a second
inflationary valley, connected to a minimum. Multiple stages of inflation might be a more general
occurrence in multiple-field inflationary models with trajectories starting next to
critical points.

Abstract
We present results from commissioning observations of the mid-IR instrument, MIRAC-5, on the 6.5 m MMT telescope. MIRAC-5 is a novel ground-based instrument that utilizes a state-of-the-art GeoSnap (2–13 µm) HgCdTe detector with adaptive optics support from MAPS to study protoplanetary disks, wide-orbit brown dwarfs, planetary companions in the contrast-limit, and a wide range of other astrophysical objects. We have used MIRAC-5 on six engineering observing runs, improving its performance and defining operating procedures. We characterize key aspects of MIRAC-5's performance, including verification that the total telescope, atmosphere, instrument, and detector throughput is approximately 10%. Following a planned dichroic upgrade, the system will have a throughput of 20% and background limiting magnitudes (for SNR = 5 and 8 hr exposure times) of 18.0, 15.6, and 12.6 for the L’, M’, and N’ filters, respectively. The detector pixels experience 1/f noise but, if the astrophysical scene is properly modulated via chopping and nodding sequences, it is less than 10% the Poisson noise from the observed background in an 85 Hz frame. We achieve close to diffraction-limited performance in the N-band and all bands are expected to reach diffraction-limited performance following the adaptive optics system commissioning. We also present an exposure time calculator calibrated to the on-sky results. In its current state, MIRAC-5 will be capable of achieving several scientific objectives including the observation of warm wide-orbit companions. Once the adaptive optics is commissioned and a coronagraph installed in 2025, MIRAC-5 will have contrast-limited performance comparable to JWST, opening new and complementary science investigations for close-in companions.

Abstract
We report the structural, mechanical and electromagnetic properties of the intermetallic compound Mn23C6. The bulk Mn23C6 sample had been synthesized using high temperature high pressure quenching method (HTHPQM), and investigated in detail by X-ray diffraction, electron microscope, magnetization and electrical resistivity measurements, etc. First-principles calculation based on Density Functional Theory ab intio simulation was carried out to calculate the bonding and electromagnetic properties of Mn23C6. Based on our experimental and simulated results, the Mn23C6 in this work is single phase of a faced-centered cubic structure with space group Fm-3m (No. 225). Determined by SEM and TEM, the bulk sample consists of monocrystal Mn23C6 crystals with 2-15 μm grain sizes, it is the quick quenching method in synthesizing process that brings such small crystal grain size. Archimedes method shows its density is 7.14 g/cm3, 95.74 % of its theoretically calculated density 7.458 g/cm3. Owing to the abundant Mn 3d electrons and a framework of strongly linked Mn atoms in Mn23C6, the electrical conductivity is up to 8.47×10-4 Ω·m, which shows that Mn23C6 is a good conductor. Our magnetic susceptibility analyses reveal there is a magnetization peak observed in M-T curve at 104 K, combined with the M-H curve and Curie-Weiss law, this peak usually means the transformation between paramagnetic and antiferromagnetic. To get an insight into the mechanism of the magnetic phase transition, we calculated the magnetic properties, and the results show that different with normal antiferromagnetic, the magnetic orders in Mn23C6 consist of three parts, the direct ferromagnetic and antiferromagnetic exchange coupling interactions between Mn atoms, and the indirect antiferromagnetic super-exchange interaction between Mn and C atoms. Therefore, we reveal that the Mn23C6 is a complex magnetic competition system including different magnetic orders and interactions, instead of the normal long-range antiferromagnetic order.
Impact of message fatigue and Individual behavioral responses on epidemiological spread in temporal simplicial networks
Authors: Fan Xiao-Nan , You Xue-mei 
Published: January 2025

Abstract
Health information spreads rapidly, which can effectively control epidemics. However, the swift dissemination of information also has potential negative impacts, increasingly attracting attention. Message fatigue refers to the psychological response characterized by feelings of boredom and anxiety that occur after receiving an excessive amount of similar information. This phenomenon can alter individual behaviors related to epidemic prevention. Additionally, recent studies indicate that pairwise interactions alone are insufficient to describe complex social transmission processes, and higher-order structures representing group interactions are crucial. To address this, we develop a novel epidemic model that investigates the interactions between information, behavioral responses, and epidemics. Our model incorporates the impact of message fatigue on the entire transmission system. The information layer is modeled using a static simplicial network to capture group interactions, while the disease layer uses a time-varying network based on activity-driven model with attractiveness to represent the self-protection behaviors of susceptible individuals and self-isolation behaviors of infected individuals. We theoretically describe the co-evolution equations using the microscopic Markov chain approach (MMCA) and get the epidemic threshold. Experimental results show that while the negative impact of message fatigue on epidemic transmission is limited, it significantly weakens the group interactions depicted by higher-order structures. Individual behavioral responses strongly inhibit the epidemic. We simulations using the Monte Carlo (MC) method demonstrate that greater intensity in these responses leads to clustering of susceptible individuals in the disease layer. Finally, we applied the proposed model to real networks to verify its reliability. In summary, our research results enhance the understanding of the information-epidemic coupling dynamics, and we expect to provide valuable guidance for managing future emerging epidemics.
HGCAL SiPM-on-tile full-stack integration with the Serenity Phase-2 DAQ hardware
Authors: Hummer F. ,   the CMS collaboration
Published: January 2025

Abstract
For the upcoming high-luminosity LHC, the endcap calorimeters of the CMS experiment will be replaced by the high granularity calorimeter (HGCAL), a sampling calorimeter using both silicon and scintillator as active materials in different regions depending on the radiation dose. This contribution describes the integration details of the scintillator-based front-end into the readout chain of HGCAL.
A prototype of the SiPM-on-tile readout chain was successfully operated in two recent beam tests at CERN SPS, demonstrating stable operation in a 3 T magnetic field and synchronization of sensor modules across different optical links.
For the first time, both the silicon and SiPM-on-tile sensors of HGCAL are integrated into a single system utilizing a Serenity-Z FPGA card. Coarse event data which would be used for trigger logic are read out synchronously for both sensor types and across multiple layers.

Abstract
The Embedded Monitoring and Control Interface (EMCI) and Embedded Monitoring Processor (EMP) system is a state-of-the-art solution developed for the Detector Control System (DCS) upgrade in the ATLAS experiment. The EMCI serves as a radiation-tolerant interface for control and monitoring data of the detector Front-End electronics. The EMP, a multi-processing System on Chip (MPSoC) platform, serves as the interface between the EMCIs and the Back-End of the DCS, providing centralized data handling and monitoring capabilities. The firmware and software ecosystem includes the EMP operating system (epos), dedicated firmware IP blocks, associated software libraries, and OPC UA based middleware applications. This paper focuses on the ongoing hardware verification and development of the firmware and software infrastructure for the EMCI-EMP system.
Segmenting spatter particles on additively manufactured surfaces using deep learning
Authors: Ng Hwee Ping , Chan Qijian , Tan Zheng Jie , Ssebaggala Ronnie , Lifton Joseph John 
Published: January 2025

Abstract
Metal additively manufactured (AM) surfaces do not exhibit the same surface features as machined surfaces. Rather than cutting marks, the additive surface may display surface features such as spatter particles, weld tracks, cracks, and surface breaking pores. These features are not well described by surface height parameters that were developed for machined surfaces. Therefore, an AM specific surface characterisation approach is required; feature based surface characterisation is a promising approach, but it requires surface features to be manually segmented which is a subjective process. In this work, a U-Net spatter particle segmentation algorithm is developed that removes the subjectivity of manual surface feature segmentation. A U-Net model is trained to segment spatter particles from optical measurements of 20 different metal AM samples. The performance of the U-Net segmentation algorithm is compared to segmenting the spatter particles using manual thresholding. The results show that the U-Net segmentation approach outperforms manual segmentations for 2 of 3 test samples considered. It is found that for 2 of 3 samples, the U-Net segmentation algorithm detects spatter particles that are missed by the manual segmentation approach. It is concluded that further training of the U-Net approach is required before it can fully supersede manual segmentation. In the future, it may be possible to replace human operators that subjectively segment surface features with robust machine learning-based surface feature segmentation algorithms. This novel application of U-Net for AM surface feature segmentation has the potential to automate surface characterisation for metal AM process optimisation, and for quality control in production environments.
Antonio Vivaldi, Oboe Sonata in C Minor, RV 53 (c. 1720)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter offers historical context and musical analysis of Antonio Vivaldi’s Oboe Sonata in C Minor, RV 53. As the foremost Italian composer of his generation, Vivaldi’s innovative style and orchestration laid the foundation for the mature Baroque concerto. Born in Venice in 1678, Vivaldi’s journey began as a virtuoso violinist, later expanding into composition. The sonata reflects his time at the Pio Ospedale della Pietà, an orphanage where he served as a violin teacher and house priest. Composed for the highly skilled figlie di coro, female musicians in the orphanage, this work exemplifies Vivaldi’s prolific output during this period. The sonata’s historical significance lies in its blurring of boundaries between church and chamber sonatas, characteristic of the Italian Baroque era. Moreover, its exploration of diverse tempos, harmonic shifts, and innovative use of the oboe as a solo instrument highlights Vivaldi’s experimental and influential approach to composition.
Tomaso Albinoni, Concerto in D Minor, Op. 9, No. 2 (c. 1722)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter examines the historical context and offers musical analysis of Tomaso Albinoni’s oboe concerto, Op. 9, No. 2. Albinoni, born in Venice, Italy, pursued music despite his family’s successful paper merchant business. He opted to be a dilettante, publishing music for connoisseurs and music lovers rather than seeking appointments in the church or court. The oboe concertos of Albinoni’s Concerti a cinque, Op. 7 and Op. 9, showcase his unique approach to composition. Drawing on his training as a singer, Albinoni aimed to evoke a vocal quality through the oboe, resulting in idiomatic and intimate chamber music. This chapter also explores the Venetian solo concerto style, with its ritornello format, brilliant solo parts, and expressive elements. The musical analysis assesses structural characteristics such as the interplay between the solo oboe and ensemble, melodic development, and textural shifts. Notably, Albinoni’s music gained popularity in Germany and influenced composers including Handel.
Georg Philipp Telemann, Partita 5, from Kleine Cammer-Music (TWV 41:e1) (1716)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter features Georg Philipp Telemann’s Partita 5 (TWV 41:e1) from Kleine Cammer-Music (1716) and discusses the historical context of Telemann’s chamber music. This music experienced renewed interest by the Early Music Movement in the 1980s, despite having been previously overshadowed by his contemporary, J.S. Bach, whose contrapuntal complexity was preferred over Telemann’s melodic galant approach. Discussion of Telemann’s life, musical precocity, and education, highlights his familiarity with and fondness for the oboe. Telemann’s influential four-decade career in Hamburg, his contributions to the city’s musical life, his collaboration with oboists, particularly Michael Böhm, and his successful music-publishing business are also explored. Each movement is analyzed to reveal the composition’s stylistic characteristics, such as its lyrical and imitative elements, rhythmic nuances, and stylized dance movements. Overall, Telemann’s instrumental writing and progressive choice to compose for the oboe demonstrate his mastery of this early eighteenth-century musical idiom.
Carl Philipp Emanuel Bach, Oboe Sonata in G Minor, H 549, Wq 135 (before 1735)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter explores the historical context and musical analysis of Carl Philipp Emanuel Bach’s Oboe Sonata in G Minor, H 549, Wq 135. C.P.E. Bach, the second surviving son of Johann Sebastian Bach, was a prolific composer and influential figure in the transition from Baroque to Classical style. Born in Weimar, Germany, he later became Court Harpsichordist in Berlin under King Frederick II and authored a significant treatise on performance practice. Composed during his teenage years in Leipzig and influenced by his father, this sonata exemplifies C.P.E. Bach’s mastery of the emerging German galant style. The first movement, Adagio, showcases dramatic and dissonant vocal qualities, Lombardic rhythms, and expressive recitative-like sections. Contrasting with it, the Allegro second movement features sonata form characteristics, offering harmonic clarity and respite. The final movement, Vivace, in simple triple meter with binary forms, includes a Minuet and variations with syncopation that echo the preceding movements.
Johann Wenzel Kalliwoda, Morceau de salon, Op. 228 (1859)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter offers commentary on Johann Wenzel Kalliwoda’s, Morceau de salon, Op. 228, composed in 1859. Kalliwoda, a Bohemian composer and violinist, lived at a time when musical style was transitioning from the Classical to the Romantic era. This chapter discusses Kalliwoda’s background, his position as Kapellmeister at Donaueschingen, and his interactions with prominent musicians like Clara and Robert Schumann and Franz Liszt. Despite his formal clarity and beautiful melodic gestures, Kalliwoda had mixed critical reception from Schumann. The work’s historical significance is discussed, as it showcases the early use of the Classical oboe’s virtuosic potential. The musical analysis highlights its compound ternary form with variations and its emotional depth, featuring passionate themes, capricious playfulness, tender lyricism, and virtuosic passages. This piece, though not part of the Paris Conservatory Concours repertoire, exemplifies the Romantic style and fills a gap in oboe repertoire from that period.
Antonio Pasculli, Concerto on Themes from Donizetti’s “La Favorita” (1840)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter offers historical context and musical analysis of Antonio Pasculli’s Concerto on Themes from Donizetti’s “La Favorita.” The term “virtuoso” emerged in the late eighteenth century to describe eminent musicians with dazzling soloistic capabilities, and Pasculli, known as the “Paganini of the oboe,” was among the most prominent virtuoso oboists. His compositions were phenomenally demanding yet avoided awkward note combinations, and he drew on familiar operatic themes from Donizetti, Verdi, and Rossini for his performances. This chapter discusses the background of Donizetti’s opera La Favorite and its complicated history before its premiere at the Paris Opéra. Pasculli’s “La Favorita” starts with an introduction drawn from the accompaniment of Act I Scene I of Donizetti’s opera and features technically demanding variations and lightning-fast cadenzas that showcase the oboist’s virtuosity. The piece’s structure, key choices, and stylistic contrasts are explored, highlighting Pasculli’s brilliance as both a performer and composer.
