Published: January 2025

AbstractThe associations of left bundle branch block (LBBB) and right bundle branch block (RBBB) with cardiovascular (CV) outcomes compared with normal QRS in heart failure patients with preserved ejection fraction (HFpEF) are unclear. We sought to determine CV morbidity, mortality, and total costs associated with LBBB and RBBB in acute HFpEF compared with those without BBB. A cross-sectional study using the 2019 NIS database analyzed adult HFpEF hospitalizations for acute heart failure, categorizing patients by LBBB, RBBB, or normal QRS. Clinical outcomes included atrial fibrillation (AF), ventricular fibrillation (VF), complete heart block (CHB), sick sinus syndrome (SSS), cardiac arrest (CA), hospitalization costs, and in-hospital mortality. Associations between BBB types and outcomes were assessed using logistic and relative risk (RR) models with propensity score weighting, validated by sensitivity analyses. A total of 334,511 hospitalizations with HFpEF including LBBB (6,818, 2%) and RBBB (7,948, 2.4%) were analyzed. Compared with normal QRS duration, LBBB was associated with VF (odds ratio [OR] = 2.47, p < 0.001), SSS (OR = 1.72, p < 0.001), CHB (OR = 2.77, p < 0.001) and greater hospitalization costs (RR = 1.15, p < 0.001) after adjusting for covariates in PS analysis. Similarly, RBBB was associated with AF (OR = 1.30, p < 0.001), VF (OR = 1.59, p = 0.033), SSS (OR = 1.72, p < 0.001), CHB (OR = 2.81, p < 0.001), CA (OR = 1.19, p < 0.001), and higher hospitalization costs (RR = 1.08, p < 0.001). These associations remained unchanged in multiple validation analyses even after additionally adjusting for obesity, hypertension, and diabetes. The length of stay was shorter in HFpEF with RBBB and LBBB subgroups compared with normal QRS. In hospitalizations of acute decompensated HFpEF, BBB was associated with an increased risk of CV outcomes and hospitalization costs.

Published: January 2025

Abstract
Background Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting approximately 1% of young adults. Severe and refractory disease commonly requires surgical excision of the affected skin. To date, there is no consensus regarding the most appropriate reconstructive algorithm.
Materials and Methods We conducted a retrospective cohort study including all HS patients who underwent surgical excision in the framework of our multidisciplinary clinic. Operative data and postoperative outcome measures were compared between patients who underwent immediate versus delayed reconstruction. Additionally, reconstructive methods were compared and risk factors for adverse postoperative outcome were identified.
Results A total of 103 patients underwent 158 surgeries for HS excision. The overall complication rate was significantly higher in patients who underwent immediate versus delayed wound closure (31 vs. 16%, p = 0.039). Any intervention for wound closure (immediate or delayed) was associated with increased risk of postoperative complications in comparison to secondary healing (33 vs. 4%, p < 0.001). With delayed closure, the average time to wound closure was 85.4 days with secondary healing only and 57 days with negative pressure wound therapy assisted closure.
Conclusion Risk factors for adverse postoperative outcome in HS surgery are multifactorial and involve both timing and method of reconstruction in addition to various patient factors. The findings of this study strengthen the notion that delayed closure of post-HS excision wounds leads to the most uneventful course in regard to postoperative adverse events; however, this may take up to 3 months. Upon deciding on a reconstructive plan, the risk-to-benefit ratio should be assessed individually weighing the pros and cons of immediate closure and delayed secondary intention.
Spectroscopic Feature of Quantum Many-Body Scar States
Authors: Wei Wenjie , Zhang Long 
Published: January 2025

Abstract
We study the dynamical correlations of nonintegrable systems with quantum many-body scar (QMBS) states generated by a ladder operator. The spectral function of the ladder operator has an exact δ-function peak induced by the QMBS states. As a concrete example, we show that in the one-dimensional (1D) spin-1 Affleck-Kennedy-Lieb-Tasaki model, the spectral function of two-magnon excitations exhibits a characteristic bow-tie shape composed of a δ-function resonance peak at momentum k = π and a continuum spectrum elsewhere. The two-magnon excitations can be observed with the resonant inelastic X-ray scattering spectroscopy on quasi-1D nickelates and other spin-1 antiferromagnetic materials, thus our work paves the way to detecting the (approximate) QMBS states in realistic materials.

Published: January 2025

Abstract
The discovery of advanced materials is the cornerstone of human technological development and progress. The structures of materials and their corresponding properties are essentially the result of a complex interplay of multiple degrees of freedom such as lattice, charge, spin, symmetry, and topology. This poses significant challenges for the inverse design methods of materials. Humans have long explored new materials through a large number of experiments and proposed corresponding theoretical systems to predict new material properties and structures. With the improvement of computational power, researchers have gradually developed various electronic structure calculation methods, such as the density functional theory and high-throughput computational methods. Recently, the rapid development of artificial intelligence technology in the field of computer science has enabled the effective characterization of the implicit association between material properties and structures, thus opening up an efficient paradigm for the inverse design of functional materials. A significant progress has been made in inverse design of materials based on generative and discriminative models, attracting widespread attention from researchers. Considering this rapid technological progress, in this survey, we look back on the latest advancements in AI-driven inverse design of materials by introducing the background, key findings, and mainstream technological development routes. In addition, we summarize the remaining issues for future directions. This survey provides the latest overview of AI-driven inverse design of materials, which can serve as a useful resource for researchers.
Phase coherence of charge-6e superconductors via a frustrated Kagome XY antiferromagnet
Authors: Song Feng-Feng , Zhang Guang-Ming 
Published: January 2025

Abstract
Recent experimental evidence for the charge-6e condensed phase in kagome superconductors has generated significant interest. We investigate the unconventional superconductivity in the kagome superconductor CsV3Sb5, focusing on the emergence of charge-6e superconductivity (SC) at temperatures higher than the conventional charge-2e SC state. By modeling the phase coherence of the SC order parameter using a frustrated antiferromagnetic XY model on an emergent kagome lattice, we show that the condensation of fractional vortices with 1/3 vorticity stabilizes phase coherence in exp(i3θ), giving rise to the charge-6e SC state. Using a tensor network approach tailored for frustrated spin systems, we identify a Berezinskii-Kosterlitz-Thouless transition at Tc
/J' ⋍ 0.075, where the unbinding of 1/3 fractional vortex-antivortex pairs transforms the system from the charge-6e SC phase to the normal phase. Below Tc
, the 1/3 fractional vortex correlations exhibit power-law decay, while the integer vortex correlations decay exponentially, reflecting the dominance of charge-6e SC in the absence of charge-2e SC. Our results provide a theoretical understanding of the charge-6e SC in two-dimensional kagome superconductors, emphasizing the interplay between fractional vortices, frustration, and topology in stabilizing this exotic SC phase.
Enhancing signal-to-noise ratio of vortex beam detection under cloud and fog conditions by combining spatial distribution and polarization information

Published: January 2025

Abstract
Vortex beams carry orbital angular momentum (OAM) and exhibit a ring-shaped intensity distribution, adding a new dimension compared to Gaussian beams. In cloudy and foggy environments, using vortex beams for detection and imaging can partially improve the signal-to-noise ratio (SNR) affected by backscattering compared to Gaussian beams. However, the improvement is limited at high concentrations. We introduce a novel approach to improve the SNR of vortex beam detection under these conditions. First, we utilized a ring filter for preliminary noise reduction, then applied polarization information to divide the data into different polarization directions. We then performed weighted summation on the one-dimensional photon counting echo data from these directions to further reduce noise. Simulation results demonstrated that this method improved SNR across various parameters. Specifically, at low reflectivity, the peak signal-to-noise ratio (PSNR) increased from 0.333 to 2.14, improving ranging accuracy. In imaging, the SNR of the processed range profile rose from 9.86 dB to 15.6 dB, and the structural similarity index (SSIM) improved from 0.590 to 0.894, indicating enhanced image quality. Therefore, our method effectively enhances both ranging accuracy and imaging quality of vortex beams under cloud and fog conditions, with potential applications in fields such as remote sensing.
Reconstructing the inflaton potential: primordial black holes and gravitational waves in slow roll and ultra slow roll single field inflation
Authors: Autieri Gabriele , Redi Michele 
Published: January 2025

Abstract
We present new single field inflationary scenarios that produce the critical abundance of primordial black holes as dark matter reconstructing the inflaton potential from an input power spectrum. The method is exact in the slow roll approximation but remains effective even when the slow roll conditions are temporarily violated such as in ultra slow roll models. With this method we construct new ultra slow roll scenarios and also models that reproduce the DM abundance within the slow roll regime. As a second application we consider a scalar power spectrum that generates a secondary gravitational wave background compatible with the one recently observed in Pulsar Timing Arrays experiments. These scenarios could be tested by future observations of μ-distortions of the CMB.

Abstract
Previous measurements of neutron energy using fast plastic scintillators while operating the Fusion Z Pinch Experiment (FuZE) constrained the energy of any yield-producing deuteron beams to less than 4.65 keV. FuZE has since been operated at increasingly higher input power, resulting in increased plasma current and larger fusion neutron yields. A detailed experimental study of the neutron energy isotropy in these regimes applies more stringent limits to possible contributions from beam-target fusion. The FuZE device operated at −25 kV charge voltage has resulted in average plasma currents of 370 kA and D–D fusion neutron yields of

keV. Characterization of the detector response has reduced the number of free parameters in the fit of the neutron energy distribution, improving the confidence in the forward-fit method. Gamma backgrounds have been measured and the impact of these contributions on the isotropy results have been studied. Additionally, a time dependent measurement of the isotropy has been resolved for the first time, indicating increases to possible deuteron beam energies at late times. This suggests the possible growth of m = 0 instabilities at the end of the main radiation event but confirms that the majority of the neutron production exhibits isotropy consistent with thermonuclear origin.
Rapid prediction method of aerodynamic noise fatigue life based on modal stress approach
Authors: Liu Yuchen 
Published: January 2025

Abstract
Hypersonic vehicles are subjected to intense aerodynamic noise loads during service, and noise fatigue life assessment is of great significance in the design stage. Aerodynamic noise load is essentially a broadband random excitation, and its fatigue life assessment mainly consists of three core modules: the compilation of the noise load spectrum, the analysis of random vibration response, and the calculation of structural fatigue damage. In order to improve the computational efficiency and strengthen the correlation between the analysis steps, this study develops a set of computational procedures based on Python programming language, which realizes the integrated and rapid processing of the fatigue life assessment of aerodynamic noise. In terms of the calculation method, a fatigue hotspot localization method based on the modal stress approach is proposed, and the modal contribution coefficient is introduced to narrow the selection range of fatigue hotspots and improve the calculation efficiency. Taking a typical stiffened plate as an example, the new method is demonstrated to have high accuracy in locating fatigue hotspots, as well as the computational program has high accuracy in fatigue life estimation. This method can significantly reduce the calculation time and storage space, and improve the utilization efficiency of resources.
Measurement of sound power of steady-state sound sources: Comsol simulation study
Authors: Su Yu 
Published: January 2025

Abstract
The application of the reverberation method in acoustics mainly comes from aeroacoustics, such as the application of reverberation room. Using a reverberation field to measure the radiated sound power of a sound source is one of the applications. For underwater acoustics, the measurement of the radiated sound power of the sound source is always a hot research issue. In this paper, the correction law of sound energy in the free field and the reverberation field is studied by Comsol simulation. It is found that the difference in sound field energy of the steady sound source in the anechoic pool and the reverberation pool is roughly a constant value, which indicates that the reverberation method is feasible to measure the sound power of the sound source in the reverberation pool, and provides a reference for the measurement of the sound power of the transient sound source. For steady-state acoustic simulation, the spectrum of the anechoic pool and reverberation pool is studied, and the relationship between the correction and frequency is measured. Since the sound source to be measured in this experiment is a broadband transient sound and the high-frequency calculation time of the simulation software is too long, the frequency of this steady-state sound field study is below 1000 Hz.

Authors: Wang Qing , Li Dongfeng , Fu Tingting , Xu Yinkang , Chen Ruiquan , Jin Tian 
Published: January 2025

Abstract
Micro-bubbles have attracted much attention in wastewater treatment due to their strong stability, long residence time in water, high mass transfer efficiency, and high Zeta potential [1-2]. Among the commonly used bubble generation methods, the ultrasonic method, Venturi method, and micro-dispersed method are the most popular methods [3–4]. To improve the efficiency of bubble generation and enhance the degree of bubble fineness, this study proposed a new Venturi tube bubble generator, mainly by adding multiple throat pipes based on the traditional Venturi tube to increase the liquid flow rate at the throat and increase the shearing area, thereby improving the bubble generation rate. This study investigated the fluid flow field distribution characteristics of the two-throat cascaded structure bubble generator based on the CFD method and analyzed the distribution of fluid velocity field, pressure field, trajectory, and turbulent kinetic energy in the bubble generator. The research results show that compared with the traditional Venturi bubble generator, the new generator not only significantly improves the bubble generation efficiency but also achieves better bubble fineness, which will provide more efficient and stable performance in real-world applications.

Authors: Weidberg A. ,   the ATLAS ITk strips collaboration
Published: January 2025

Abstract
This paper reviews the bus tapes used for the barrel and end cap detectors for the ATLAS
ITk strip detector. The long copper/polyimide tapes with narrow track and gap are very challenging
to produce with an acceptable yield. Two different technologies for these tapes are
compared. After several iterations, barrel and end cap tapes are in production at two different
manufacturers. Results from the electrical and dimensional QC show that both approaches meet the
tight specifications. Tests of the radiation tolerance are also discussed.

Abstract
Following the Phase-II upgrade during Long Shutdown (LS3),
the LHC aims to reach a peak instantaneous luminosity of
7.5×
1034 cm-2 s-1, which
corresponds to an average of around 200 inelastic proton-proton
collisions per beam-crossing (every
25 ns). To cope with these
conditions, the ATLAS Inner Detector will be replaced by a new
all-silicon system — the Inner Tracker (ITk). The ITk will be
operational for more than ten years, during which time ATLAS is
expected to record approximately
4000 fb-1 of data. The ITk's
pixel sub-system is based on hybrid pixel modules with new silicon
sensors and readout chips. These studies focus on testbeam
campaigns undertaken to study the spatial resolution and
efficiencies of hybrid pixel detector modules based on the first
large-structure prototype front-end readout chip — the RD53A —
using planar silicon sensors. These devices have been irradiated to
replicate the effect of the high radiation environment present
during operation in the ATLAS detector. Results for devices using
sensors with different punch-through bias structures and using
different readout modes are summarised. Those with sensors
incorporating a punch-through bias structure are found to exhibit
systematically lower efficiency than those without, as a result of
local areas of relative inefficiency around the punch-through
dots. Despite this, all devices measured are found to satisfy the
requirement of 97% efficiency at
V
bias = 400 V
after being irradiated to end-of-life fluence.
Locomotion design of transverse ledge brachiation robot with active wrist joint for lateral posture compensation
Authors: Pangestu Reno , Yeh Shu-Ting , Lin Chi-Ying 
Published: January 2025

Abstract
A transverse ledge brachiation robot is designed to move transversely along a ledge on a vertical wall by generating energy from the swinging motion of its lower limbs. This method reduces the force required by the upper limbs to propel the robot forward. However, previously developed robots often encounter a common issue: lateral posture deviation, which is typically caused by slippage when the grippers grasp the ledge. Without compensation, this deviation can increase the risk of falling during continuous brachiation cycles. To address this problem, we propose an active wrist joint mechanism utilizing a feedback control approach as the compensator to effectively correct gripper position deviations. In our robot design, we develop a motion control strategy that coordinates the upper and lower limbs in order to maintain the swing energy that can be transferred to the subsequent cycles. Then we propose a potential energy-based phase switching condition in the motion control strategy in order to simplify the computation process. Simulation results demonstrate that the optimized parameter for compensation effectively maintains the gripper’s position relative to the ledge throughout 55 brachiation cycles. Furthermore, experiment validation shows that this posture compensation reduces deviation by one-third compared to results without compensation. This study has demonstrated a 68% improvement in energy consumption efficiency for continuous transverse brachiation compared to the previous generation, as well as a 37% improvement over transverse ricochetal brachiation locomotion.
Thermal charging-discharging analysis of PCM cylinder for amine-functionalized MWCNT-doped paraffin wax as a phase change material
Authors: Prasad Daya Shankar , Singh Pradeep Kumar 
Published: January 2025

Abstract
This Experimental study focuses on analyzing the impact of amine-functionalized MWCNTs (multi-walled carbon nanotubes) doping on the thermal performance of paraffin wax, aiming to enhance its potential as an efficient phase change material (PCM) for advanced energy storage applications. Mixing of MWCNT (nanomaterial) into paraffin wax (PW) at different volume percentages of 0.20, 0.40, 0.80 and 1.6, results in enhancement of the properties of PCM (paraffin wax). Experimental investigations show that as the flow rate increases from 6.25 ml s−1 to 25 ml s−1, the time taken for both charging and discharging the PCM cylinder decreases. The results of doping nanomaterials into PW show an enhancement in the thermal conductivity of the PCM by 10.94%, 18.86%, 24.15%, and 34.33% for volume percentages of 0.20%, 0.40%, 0.80%, and 1.60%, respectively. Moreover, optimal performance was observed at 0.80 vol% MWCNT, with a 63.3% reduction in charging time and a 50% increase in discharging time under specific flow rates of the heat transfer fluid. These findings suggested that the amine functionalized MWCNT nanoparticle is very effective and useful to enhance the thermal energy properties of paraffin wax and hence improves the thermal energy storage capacity that can be further used for various applications.
Minimal Rationality and the Web of Questions
Authors: Hoek Daniel 
Published: January 2025

Abstract
This chapter proposes a new account of bounded or minimal doxastic rationality, based on the notion that beliefs are answers to questions. The core idea is that minimally rational beliefs are linked through the thematic connections between them, rather than entailment relations. Minimally rational beliefs are not deductively closed, but they are closed under parthood (where a part is an entailment that answers a smaller question). And instead of avoiding all inconsistency, minimally rational believers only avoid blatant inconsistencies (where some beliefs are blatantly inconsistent when they contradict one another on a particular question). Rather than cohering into a single overall world view, beliefs are more loosely connected in what is best described as a web of questions. This view of minimally rational belief naturally gives rise to an account of deductive inquiry on which deductive reasoning is a matter of posing new questions.
