The streaming model for the three-point correlation function and its connection to standard perturbation theory
Authors: Pugno A. , Eggemeier A. , Porciani C. , Kuruvilla J. 
Published: January 2025

Abstract
Redshift-space distortions (RSDs) present a significant challenge in building models for
the three-point correlation function (3PCF). We compare two possible lines of attack: the
streaming model and standard perturbation theory (SPT). The two approaches differ in their
treatment of the non-linear mapping from real to redshift space: SPT expands this mapping
perturbatively, while the streaming model retains its non-linear form but relies on simplifying
assumptions about the probability density function (PDF) of line-of-sight velocity differences
between pairs or triplets of tracers. To assess the quality of the predictions and the validity
of the assumptions of these models, we measure the monopole of the matter 3PCF and the first two
moments of the pair- and triplewise velocity PDF from a suite of N-body simulations. We also
evaluate the large-scale limit of the streaming model and determine under which conditions it
aligns to SPT. On scales larger than 10 h
-1 Mpc, we find that the streaming model
for the 3PCF monopole is dominated by the first two velocity moments, making the exact shape of
the PDF irrelevant. This model can match the accuracy of a Stage-IV galaxy survey, if the
velocity moments are measured directly from the simulations. However, replacing the measurements
with perturbative expressions to leading order generates large errors already on scales of
60–70 h
-1 Mpc. This is the primary drawback of the streaming model. On the
other hand, the SPT model for the 3PCF cannot account for the significant velocity dispersion that
is present at all scales, and consequently provides predictions with limited accuracy. We
demonstrate that this issue can be approximately addressed by isolating the large-scale limit of
the dispersion, which leads to typical Fingers-of-God damping functions. Overall, the SPT model
with a damping function provides the best compromise in terms of accuracy and computing time.
Electrical impedance tomography meets reduced order modelling: a framework for faster and more reliable electrical conductivity estimations

Published: January 2025

Abstract

Objective. Inclusion of individualised electrical conductivities of head tissues is crucial for the accuracy of electrical source imaging techniques based on electro/magnetoencephalography and the efficacy of transcranial electrical stimulation. Parametric electrical impedance tomography (pEIT) is a method to cheaply and non-invasively estimate them using electrode arrays on the scalp to apply currents and measure the resulting potential distribution. Conductivities are then estimated by iteratively fitting a forward model to the measurements, incurring a prohibitive computational cost that is generally lowered at the expense of accuracy. Reducing the computational cost associated with the forward solutions would improve the accessibility of this method and unlock new capabilities. Approach. We introduce reduced order modelling (ROM) to massively speed up the calculations of these solutions for arbitrary conductivity values. Main results. We demonstrate this new ROM-pEIT framework using a realistic head model with six tissue compartments, with minimal errors in both the approximated numerical solutions and conductivity estimations. We show that the computational complexity required to reach a multi-parameter estimation with a negligible relative error is reduced by more than an order of magnitude when using this framework. Furthermore, we illustrate the benefits of this new framework in a number of practical cases, including its application to real pEIT data from three subjects. Significance. Results suggest that this framework can transform the use of pEIT for seeking personalised head conductivities, making it a valuable tool for researchers and clinicians.

Published: January 2025

Abstract
This work describes a custom electronics card named PicoTDC board developed at INFN Bologna, whose goal is to provide fast timing measurements to generic detectors. The board is able to connect to different front-end electronics using a common FMC (FPGA Mezzanine Connector) interface. The fast timing measurements are provided by 2 PicoTDC ASICs from CERN, which supply 128 channels with 3.05 ps LSB. Design choices and performance of the card are discussed. We are also designing a family of front-end cards compatible with the PicoTDC board to improve the flexibility of the board itself and ease the connection to generic detectors and their front end electronics. We then measured the timing resolution achievable with this board, which is compatible with the PicoTDC expected performances.

Amorphization dependent recrystallisation of Sb2Te3
Authors: Adanan Nur Qalishah , Wredh Simon , Yang Joel K W , Simpson Robert E 
Published: January 2025

Abstract
Understanding state-dependent crystallisation kinetics is important for the modelling and design of phase change material (PCM)—based devices, such as multi-level switches. We show how the level of amorphousness (disorder) of antimony-telluride (Sb2Te3) can be controlled using pulsed laser heating, and that the recrystallisation temperature strongly depends on the local atomic configurations in the amorphous structure. Indeed, when Sb2Te3 is amorphized with higher laser powers, its subsequent recrystallisation temperature increases by up to 23 °C yet, and counterintuitively the recrystallisation activation energy decreases. This leads to shorter minimum recrystallisation times. This effect is important because it provides a means to switch PCM devices at higher rates through a catalyst-like effect. The optical properties of Sb2Te3 can be gradually tuned by the level of crystallographic disorder. The amorphousness of PCMs provides a further degree-of-freedom to achieve multi-level programmability and tune the switching energy of devices.
Phonon-mediated renormalization of exciton energies and absorption spectra in polar semiconductors
Authors: Schebek Maximilian , Pavone Pasquale , Draxl Claudia , Caruso Fabio 
Published: January 2025

Abstract
We investigate the influence of vibrational screening on the excitonic and optical properties of solids based on first-principles electronic-structure calculations. We solve the Bethe–Salpeter equation–the state-of-the-art description of excitons–by explicitly accounting for phonon-assisted screening effects in the screened Coulomb interaction. We go beyond recently studied absorption onsets and account for screening effects on all excitonic states. In the examples of the polar semiconductors ZnS, MgO, and GaN, the exciton binding energies at the absorption onset are found to be renormalized by a few tens of meV. Similar effects are also found for higher-lying unbound electron–hole pairs, leading to red–shifts of the absorption peaks by up to 50 meV. Our analysis reveals that vibrational screening is dictated by long-range Fröhlich coupling involving polar longitudinal optical phonons, whereas the remaining vibrational degrees of freedom are negligible. Overall, by elucidating the influence of phonon screening on the excitonic states and absorption spectra of these selected ionic semiconductors, this study contributes to advancing the ab initio methodology and the fundamental understanding of exciton–phonon coupling in solids.

Published: January 2025

Abstract
This study investigates the role of electrode density in capturing resting-state brain activity, an area of significant clinical relevance, where electroencephalography (EEG) is favored for its cost-efficiency. We analyze how different electrode configurations affect the precision of cortical current density estimation in EEG recordings. Using exact Low-Resolution Electromagnetic Tomography (eLORETA), we estimated the cortical current density in regions of interest linked to Resting State Networks (RSN). Point process analysis was employed to identify regions of high activity over time, revealing dynamic brain salient activity patterns, or brain maps. We evaluated the impact of electrode density by comparing 64-channel and 20-channel configurations and found that both configurations yielded similar and consistent brain maps. To confirm the robustness of our approach, we assessed the Berger effect in eyes-closed (EC) versus eyes-open (EO) conditions, observing that the functional differences between EC and EO states remained stable regardless of electrode density, aligning with previous research. Conversely, randomization of data or the use of non-homogeneous electrode configurations disrupted the resulting patterns, highlighting the physiological relevance of our methodology. Overall, our results demonstrate that this approach reliably captures the spatiotemporal dynamics of brain activity, even with fewer electrodes, and holds promise for broader clinical applications.

Published: January 2025

Abstract
Colour centres in diamonds have attracted considerable interest for quantum sensing applications. Boasting great photostability, long coherence times at room temperature and unique electronic properties that allow for optical initialization and readout of their quantum state, colour centres have found use in a variety of techniques for thermometry, magnetometry and nanoscale spectroscopy. Coupled with the possibility of preparing nanoparticles, their excellent biocompatibility and versatile surface chemistry that allows for functionalization and fine-tuning of surface properties, diamonds hosting colour centres have proven to be a versatile and flexible platform for measurements of local properties in a wide range of biological and biochemical systems. In this perspective, we summarize the key properties of the colour centres in diamonds and how different surface chemistry impacts their electronic properties. Finally, we discuss the crucial role of surface chemistry in various sensing applications and highlight the potential of diamond materials to address current challenges in quantum science and technology.

Abstract
This chapter offers historical context and musical analysis of Alessandro Marcello’s Oboe Concerto in D Minor. Marcello, a versatile figure in eighteenth-century Venice, made significant contributions to several disciplines, including poetry and government. This chapter explores Marcello’s background, offering cultural context, and discusses the rhetorical nature of music in the Baroque era, emphasizing the communication between the composer, performer, and audience. The commentary extends to J.S. Bach’s harpsichord transcription of Marcello’s concerto and the various editions that emerged, to highlight the importance of treating Marcello’s original composition as the true form of the text. The analysis focuses on the structure and affective qualities of each movement, including the ritornello format of the first movement, the harmonic intricacies of the second movement, and the sprightly character of the third movement. Contemporaneous key associations with D minor regarded as a serious and devout key are also considered.
George Frideric Handel, Sonata in C Minor, Op. 1, No. 8, HWV 366 (1711–1712)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter explores the life and music of George Frideric Handel, with a focus on his Sonata Op. 1, No. 8. Handel, born in 1685, grew up in a middle-class family in Halle, Germany, and showed exceptional musical ability from a young age. He received patronage and support from influential figures, which led him to Italy, where he gained further recognition and composed numerous works. Handel’s oboe sonatas, including Op. 1, No. 8, offer serious and expressive movements. From the lyrical Largo to the imitative Allegro and expressive Adagio, the work culminates with a lively Bourée angloise combining elements from both camera and chiesa formats. Handel’s ability to evoke emotional states through instrumental music and his entrepreneurial approach to composition are highlighted as well. Despite the perception that Handel focused more on vocal music, his chamber works, including his oboe sonatas, showcase Handel’s compositional mastery.

Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter examines the artistic journey and stylistic evolution of French composer Henri Dutilleux, focusing specifically on his Sonata for Oboe and Piano (1947). Dutilleux’s musical development was influenced by his familial artistic heritage, early exposure to chamber music, and formal education at the Paris Conservatory. His eclectic musical language reflects his fascination with both traditional and modern elements, leading to compositions marked by alternating simplicity and complex structures. The Sonata for Oboe and Piano, initially composed as a test piece, exemplifies Dutilleux’s unique blend of tonality, modality, and octatonic scales. Despite his own disapproval of his early works, these compositions—particularly the Oboe Sonata—have been regarded as crucial to Dutilleux’s musical development. The Sonata’s innovative use of form, cyclicity, and polytonality illuminate his approach to composition, blending traditional techniques with an innovative approach to color, structural variety, and harmonic complexity.

Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
Madeleine Dring (1923–1977) was a British composer known for her lyrical and dramatic works. Born into a musical family, her innate talent was evident at an early age, and she attended the Royal College of Music. Her compositions for piano, voice, and notably, for her husband, oboist Roger Lord, solidified her place in twentieth-century British music. As a dedicated performer, Dring’s works offer profound reflections of her life, radiating with her creativity, wit, and spiritual depth. After her death, her composition, Three Piece Suite for Oboe and Piano (1984), was transcribed by Lord from the original work for harmonica. Organized in a fast-slow-fast format, each movement exhibits thematically driven structures and evocative moods. The suite’s distinctive fusion of theatrical brilliance, lyricism, and chromatic innovation stands as a testament to Dring’s creative genius and her unique contribution to the music of her era.

Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter offers historical context and musical analysis of Luciano Berio’s Sequenza VII (1969). Born in Italy during the interwar period, Berio was a key figure in the midcentury European avant-garde, developing his compositional voice amid the significant cultural shifts and technological advancements of the time. Discussion includes Berio’s formative influences, encompassing his familial musical background and his exposure to diverse styles during his studies at the Milan Conservatory and the Darmstadt Summer School. Sequenza VII for oboe emerges from Berio’s belief in the transformative power of art, underpinned by the notion of musical hybridity. Strongly tied to the virtuosity of Heinz Holliger, this piece is notable for its transformational unfolding of a registrally fixed harmonic field, extended techniques, spatial notation, and use of a drone pitch, B1, throughout. Analysis of this work reveals Berio’s innovative use of chromatic saturation, temporal pacing, and motivic structuring.

Reena Esmail, Jhula Jhule (2013)
Authors: Lewis Nora Anderson 
Published: January 2025

Abstract
This chapter offers historical context and analysis of Reena Esmail’s Jhula Jhule (2013), a work that intricately combines Indian folk music and Western classical music. As a first-generation Indian American composer, Esmail’s compositions often explore and express her dual cultural identity. She received her training in Western classical music at prestigious institutions such as the Juilliard School and Yale University. However, feeling a cultural disconnect, Esmail sought to incorporate her Indian heritage into her music. This led to a year-long study of Hindustani music in India as a Fulbright Scholar under the guidance of sitarist Gaurav Mazumdar. In Jhula Jhule, Esmail skillfully interweaves two Indian folk songs from her familial heritage, creating a poignant musical tapestry. The analysis shows how Esmail employs Western musical concepts while honoring traditional Indian musical techniques and principles. This examination highlights Esmail’s unique contribution to contemporary music through her innovative approach to transcultural composition.
Body Contouring Finesse: Dynamic Definition Liposculpture and Bipolar Radiofrequency Microneedling
Authors: Hoyos Alfredo E , Perez Pachon Mauricio E , Vranis Neil M 
Published: January 2025

Abstract
Dynamic definition liposculpture (HD2) is considered a highly sought after procedure in body sculpting surgery by patients. Radiofrequency microneedling is a cutting edge technology with evidence-based outcomes demonstrating skin tightening and retraction. These ancillary procedures complement and enhance the results of dynamic definition liposculpture. A retrospective review of patient records from 2022 to 2024 was conducted. All patients who underwent high definition (HD) or HD2 in combination with fractional radiofrequency microneedling treatments by the senior author (A.E.H.) were included. Data collected included patient demographics, areas treated, and any complications. A total of 86 patients were included: 16 in 2022, 62 in 2023, and 8 in 2024. The most frequently treated area was the abdomen, followed by the back, face, neck, thighs, and arms. The average age of patients was 40.0 years in 2022, 40.8 years in 2023, and 44.4 years in 2024. The average BMI was 23.9 kg/m2 in 2022, 24.3 kg/m2 in 2023, and 25.2 kg/m2 in 2024. Minimal complications were observed, with some patients requiring further interventions such as scar correction and nevus resection. Avoiding superficial liposuction by relying on radiofrequency microneedling to target the adipose tissue directly beneath the dermis decreases the risk for iatrogenic (cannula related) superficial contour irregularities and makes the overall operation safer and more reliable.
