Published: December 2024

AbstractAccess and efficient resource utilization remain critical challenges in healthcare, often leading to long wait times despite unfilled outpatient appointments. Epic Fast Pass (EFP), an innovative feature within the Electronic Health Record (EHR), has improved outpatient appointment scheduling, reduced wait times, and enhanced access in routine appointments. Guided by the principles of a learning health system, we describe the novel application of EFP to imaging and procedural services, specifically outpatient echocardiograms and endoscopies. We collected user data over 15 months for echocardiograms and 4 months for endoscopies. For echocardiograms, 41.26% of patients accepted an offer, improving their appointment times by an average of 12.8 days. For endoscopies, 48.35% accepted, with an average improvement of 50.43 days. Our results demonstrate that rescheduling tools for outpatient imaging and procedural appointments are both feasible and promising, with the potential to enhance patient access and optimize resource utilization.

Authors: Zhang Jiajie , Fenton Susan H. 
Published: December 2024

AbstractArtificial intelligence (AI) fundamentally transforms healthcare education as a knowledge enterprise, creating a distributed cognitive system composed of the human brain, which remains relatively unchanged, and AI-based knowledge and cognitive functions, which have accelerated exponentially in scale and power. Education must focus on developing skills to collaborate with AI and on achieving outcomes like problems solved and discoveries made. Curriculum and education policies also need to adapt to this transformation.

Published: December 2024

AbstractThis study introduces an adaptive polynomial predictive filter (APPF) to address the issues of inconsistent and interrupted sensor data in estimation and prediction tasks. The APPF utilizes a polynomial prediction model to estimate time‐variant/time‐invariant sensor data through polynomial extrapolation. A key feature of the APPF is the autonomous determination of an accurate polynomial order, which reflects the nonlinearity level of the system. This dynamic adjustment allows the APPF to effectively capture the complex dynamics of nonlinear systems without manual tuning, thereby ensuring an accurate sensor data estimation and fusion. This study primarily focuses on validating the feasibility of the APPF method, and the theoretical basis, implementation, and performance evaluation of the APPF are covered, with results from MATLAB simulations and laboratory‐based practical experiments comparing the APPF with Kalman filter techniques. Experiments using Hall effect sensors, which provide precise localization by detecting magnetic signals, were conducted to assess the effectiveness of the APPF in addressing the sensor data variances and disturbances commonly encountered in surgical robotic tracking. The findings demonstrate that the APPF significantly enhances estimation and prediction accuracy, highlighting its potential for improving sensor data reliability in various applications.
An innovative semantically guided SAR imaging and target enhancement method
Authors: Zhou Guoru , Zhang Zhe , Zhang Bingchen , Wu Yirong 
Published: December 2024

AbstractConventional sparse synthetic aperture radar (SAR) imaging methods apply regularisation to constrain scene priors. However, these methods often neglect specific target regions, resulting in undifferentiated imaging. This letter introduces a novel network for sparse SAR imaging and target region enhancement, using target segmentation semantic information to integrate a modified attention mechanism into the image formation process. The complex‐valued convolution is used to handle SAR's complex‐valued data. Additionally, SAR imaging operator and its inverse operator accelerate echo processing. Experiments show improvements in the target–background ratio (TBR) and overall reconstruction quality across various downsampling scenarios.
The question of thermoelectric devices (TEDs) in/efficiency—A practical research considering thermoelectric generators (TEGs)
Authors: Bayendang Nganyang Paul , Balyan Vipin , Kahn Mohamed Tariq 
Published: December 2024

AbstractThermoelectricity is a versatile clean energy technology; however, its in/efficiency has been a question of debate. Thus, this practical study focuses on thermoelectric devices' (TEDs') performance when operated as thermoelectric generators (TEGs). Sixteen identical TEDs (TEC‐12706 of the same made and model) were operated as TEGs under the same experimental setup and test modalities with a hotside temperature between ∼20°C and ∼100°C and a coldside temperature of ∼20°C, to practically and comparatively examine the TEGs voltage production and energy conversion in/efficiency. The findings revealed that, while it's already common knowledge that a TEG output voltage is proportional to its temperature difference as evident in all the TEGs used in the study; however, as the TEGs temperature difference proportionally increases, some of the TEGs relatively produced less, the same and more output voltages at certain temperature differences compared to others. For example, TEG1 and TEG3 produced almost the same output voltages throughout; however, at ∼100°C hotside temperature, TEG3 produced 3.16 V, whereas TEG1 produced 2.90 V. While such widespread TEGs discrepancies can be mostly attributed to bad manufacturing/poor workmanship, they are usually misconstrued by some as a generic inherent thermoelectricity technology limitations which this study highlights.

Context. Galaxy mergers are an important and complex phase during the evolution of galaxies. They may trigger nuclear activity and/or strong star forming episodes in galaxy centres that potentially alter the evolution of the system.
Aims. As part of the guaranteed time observations program Mid-Infrared Characterization Of Nearby Iconic galaxy Centers (MICONIC), we used the medium-resolution spectrometer (MRS) of the Mid-Infrared Instrument on board the James Webb Space Telescope (JWST) to study NGC 6240. We aim to characterise the dual active galactic nuclei (AGN), the ionised gas outflows, and the main properties of the interstellar medium over a mapped area of 6.6″ × 7.7″.
Aims. We obtained integral field spectroscopic mid-infrared data (wavelength from 4.9 to 28 μm) of NGC 6240. We modelled the emission lines through a kinematic decomposition that accounts for the possible existence of various components.
Methods. We have resolved both nuclei of NGC 6240 for the first time in the full 5−28 μm spectral range. The fine structure lines in the southern (S) nucleus are broader than for the northern (N) nucleus (full width at half maximum of ≥1500 versus ∼700 km s−1 on average, respectively). High excitation lines, such as [Ne V], [Ne VI], and [Mg V], are clearly detected in the N nucleus. In the S nucleus, the same lines can be detected but only after a decomposition of the polycyclic aromatic hydrocarbon features in the integrated spectrum, due to a combination of a strong mid-IR continuum, broad emission lines, and intense star formation (SF). The SF is distributed all over the mapped field of view of 3.5 kpc × 4.1 kpc (projected), with the maximum located around the S nucleus. Both nuclear regions appear to be connected by a bridge region that is detected with all the emission lines. Based on the observed MRS line ratios and the high velocity dispersion (σ ∼ 600 km s−1), shocks also dominate the emission in this system. We detected the presence of outflows as a bubble north-west from the N nucleus and at the S nucleus. We estimated an ionised mass outflow rate of 1.4 ± 0.3 M⊙ yr−1 and 1.8 ± 0.2 M⊙ yr−1, respectively. Given the derived kinetic power of these outflows, both the AGN and the starburst could have triggered them.
What attracts sustainable fund flows? Prospectus versus ratings*
Authors: Birk Kevin , Jacob Stefan , Wilkens Marco 
Published: December 2024

AbstractMany studies indicate that sustainability ratings attract high fund flows, reinforcing the dominant role of rating agencies for the fund industry. However, these studies neglect prospectus information, which is very likely to influence investors' decisions. By analyzing 23,606 equity mutual funds and ETFs, we find that self-declared sustainability statements in fund prospectus are the main driver of retail and institutional fund flows. Additionally, sustainability references in the fund name and the fund’s employed sustainability investment approach significantly affect flows. External sustainability ratings on the other hand appear to be less relevant for fund flows than previous studies suggest.
Influence of employee impact on their evaluation of enterprise digital capability: a mediated moderation model
Authors: Zhou Qiwei , Zang Lingqiao , Fu Feiqiang 
Published: December 2024

AbstractDigital transformation elicits new management challenges. Studies have investigated its direct impact on employee behavior, but how employees evaluate enterprise digital capability, and its underlying mechanism remains unknown. Employees’ evaluations of enterprise digital capability tend to shape their subsequent attitudinal and behavioral responses towards the digital transformation, which may ultimately stress influence on the overall transformation initiative in a “bottom-up” manner. Drawing from work design theory and conservation of resources theory, this study proposes that through the implementation of effective work design strategies, organizations can foster a sense of employee impact, and further construes a mediated moderation model regarding how the relationship between employee impact and their evaluation of enterprise digital capability is moderated by empowering leadership, and further, mediated by cognitive adjustment at work. Empirical results based on a three-wave survey featuring 424 full-time Chinese employees show that: employee impact predicts evaluation of enterprise digital capability, and such linkage is not only enhanced by empowering leadership but also strengthened by cognitive adjustment at work. The moderation effect of empowering leadership in the relationship between impact and digital capability evaluation is further mediated by cognitive adjustment at work. We explore the antecedents and mechanisms of differences in employees’ evaluation of enterprise digital capability and propose takeaway managerial messages.
The relevance of degenerate states in chiral polaritonics
Authors: Bustamante Carlos M. , Sidler Dominik , Ruggenthaler Michael , Rubio Ángel 
Published: December 2024

In this work, we theoretically explore whether a parity-violating/chiral light–matter interaction is required to capture all relevant aspects of chiral polaritonics or if a parity-conserving/achiral theory is sufficient (e.g., long-wavelength/dipole approximation). This question is non-trivial to answer since achiral theories (Hamiltonians) still possess chiral solutions. To elucidate this fundamental theoretical question, a simple GaAs quantum ring model is coupled to an effective chiral mode of a single-handedness optical cavity in dipole approximation. The bare matter GaAs quantum ring possesses a non-degenerate ground state and a doubly degenerate first excited state. The chiral or achiral nature (superpositions) of the degenerate excited states remains undetermined for an isolated matter system. However, inside our parity-conserving description of a chiral cavity, we find that the dressed eigenstates automatically (ab initio) attain chiral character and become energetically discriminated based on the handedness of the cavity. In contrast, the non-degenerate bare matter state (ground state) does not show energetic discrimination inside a chiral cavity within a dipole approximation. Nevertheless, our results suggest that the handedness of the cavity can still be imprinted onto these states (e.g., angular momentum and chiral current densities). Overall, the above findings highlight the relevance of degenerate states in chiral polaritonics. In particular, because recent theoretical results for linearly polarized cavities indicate the formation of a frustrated and highly degenerate electronic ground state under collective strong coupling conditions, which, likewise, is expected to form in chiral polaritonics and, thus, could be prone to chiral symmetry breaking effects.
Electrical transport and rectification behavior in monolayer MoSi2N4 with different metal electrode contacts
Authors: Jia Jianming , Shi Daning , Feng Xiaoqin , Yang Yan 
Published: December 2024

Abstract
Monolayer MoSi2N4 has been proposed as a promising channel material for new-generation nanodevices, owing to its superb ambient stability and exceptional electronic properties. Despite recent experimental and theoretical research revealing the interfacial characteristics of monolayer MoSi2N4 in contact with metals, the effect of different metal electrode contacts on the electrical transport of MoSi2N4 within the framework of device configuration remains unexplored. Using first-principles transport calculations, this study investigates the electrical properties of metal semiconductor devices with monolayer MoSi2N4 placed between MoSi2N4-metal (Au, Ag, Pt, and Ti) electrodes. While n- and p-type Schottky contacts are formed in Au_MoSi2N4_Au and Pt_MoSi2N4_Pt, respectively, quasi- and entire ohmic contacts are achieved in Ag_MoSi2N4_Ag and Ti_MoSi2N4_Ti, respectively. I–V characteristics show that devices with asymmetric metal electrodes exhibit pronounced rectification behaviors. The rectification ratio of Ag_MoSi2N4_Au exceeds 106, which is related to the extreme asymmetric band arrangement in devices driven by a bias polarity. These results provide valuable guidelines for the development of high-performance MoSi2N4-based electrical nanodevices.
Practical parameters for extending the velocity range when applying a partial inversion pulse to the ultrasonic time-domain cross-correlation method
Authors: Wada Sanehiro , Furuichi Noriyuki 
Published: December 2024

Abstract
This paper describes a method to reduce false velocity detection by applying a partial inversion pulse (PIP) to the ultrasonic time-domain cross-correlation (UTDC) method. False detection occurs when we attempt to expand the velocity range of UTDC (same as the aliasing limit of the pulsed Doppler method). Specifically, the effects of three parameters that are important for practical use and have not been discussed before were examined, and recommended values for them were determined. The UTDC method can obtain the flow velocity profile along an ultrasonic beam by transmitting and receiving pulses. The PIP is a waveform that is phase-inverted within a pulse that is half as short as a conventional waveform, and it can reduce false detection by simply applying to the UTDC method. The three important parameters are the width of the reference window, the number density of reflective particles in the measurement volume, and the threshold for the cross-correlation coefficient. The PIP waveform was modeled, and the influences of these parameters were evaluated by simulations that calculate the correlation coefficient for single pulses and for waveforms overlapped with up to three pulses. In addition, the method was also experimentally verified in a pipe flow. Tests were also carried out with various number densities of reflectors. From these results, the effect of applying the PIP was confirmed for all values of these parameters. Specifically, the PIP can shift and reduce the peak of the first sidelobe in the correlation coefficient. As recommended values for each parameter, the experimental results showed that the width of the reference window should be equal to the pulse width, the number density of reflectors should be about one in the measurement volume, and the threshold value of the correlation coefficient should be about 0.5–0.7.
Acquiring pulse a priori information for chirp transform spectrometer systems through phase error measurements
Authors: Hu Baifan , Liu Mengwei , Xie Lurui , Wang Wen 
Published: December 2024

Abstract
With the rapid advancement in deep-space exploration, back-end systems such as chirp transform spectrometers (CTSs) must be equipped with larger bandwidths, higher frequency resolutions, and enhanced sensitivities. Phase errors in chirp signals distort pulse compression waveforms, significantly affecting CTS system performance. To correct the distorted pulses, we acquire a priori information about the pulse waveform by measuring the phase errors in the CTS system. This paper measures and analyzes phase errors in the expander and compressor signals of a 1 GHz bandwidth CTS system. We discuss the impact of these phase errors on pulse waveforms, system frequency resolution, sensitivity, and other critical performance parameters. Additionally, we plot the in-band phase error curves for the system. By utilizing these phase error curves, we can determine the phase error for any input frequency, thereby providing valuable prior information for pulse compression waveform correction. This approach is crucial for guiding subsequent error optimization and compensation in the CTS system.
Two Repeated Quasi-periodic Oscillations in the FSRQ S5 1044+71 Observed by TESS

Published: December 2024

Abstract
In this work, we report for the first time two repeated quasi-periodic oscillations (QPOs) in the light curve of the Flat Spectrum Radio Quasar S5 1044+71. This source was observed by the Transiting Exoplanet Survey Satellite in multiple sectors. We used the generalized Lomb-Scargle periodogram method and weighted wavelet Z-transform method to search for significant periodic signals. The main results are as follows: We found QPOs of ~7.0 days (persisted for 4 cycles, with a significance of ~3.5σ) and ~7.3 days (persisted for 5 cycles, with a significance of ~3.8σ) in the light curves of Sector 47 and EP1, respectively. Considering range of error, we regard them to be the same. We discussed two likely models of these rapid quasi-periodic variations: One comes from the jet and the other from the accretion disk. For the first one, we consider kink instability of the jet as a plausible explanation. Second, the QPO probably comes from the main hot spots in the accretion disk, which are located approximately within the innermost stable circular orbit allowed by general relativity. Based on this model, we estimate the mass of the black hole in S5 1044+71 to be 3.49 × 109

Published: December 2024

Abstract
We present simulation results examining the presence and behavior of standing shocks in zero-energy low angular momentum advective accretion flows and explore their (in)stability properties, taking into account various values of specific angular momentum, λ
0. Within the range 10−50R

g
(where R

g
denotes the Schwarzschild radius), shocks are discernible for λ
0 ≥ 1.75. In the special relativistic hydrodynamic simulation when λ
0 = 1.80, we find the merger of two shocks resulted in a dramatic increase in luminosity. We present the impact of external and internal flow collisions from the funnel region on luminosity. Notably, oscillatory behavior characterizes shocks within 1.70 ≤ λ
0 ≤ 1.80. Using free–free emission as a proxy for analysis, we show that the luminosity oscillations between frequencies of 0.1−10 Hz for λ
0 range as 1.7 ≤ λ
0 ≤ 1.80. These findings offer insights into quasi-periodic oscillation emissions from certain black hole X-ray binaries, exemplified by GX 339-4. Furthermore, for the supermassive black hole at the Milky Way's center, Sgr A*, oscillation frequencies between 10−6 and 10−5 Hz were observed. This frequency range, translating to one cycle every few days, aligns with observational data from X-ray telescopes such as Chandra, Swift, and XMM-Newton.
ATLAS pixel detector overview
Authors: Kakoty Niraj ,   the ATLAS ITk collaboration
Published: December 2024

Abstract
In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical
bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost part of the ITk will consist of a pixel detector, with an active area of about 13 m2. To deal with the changing requirements in terms of radiation hardness, power dissipation and production yield, several silicon sensor technologies will be employed in the barrel and endcap layers. The ITk project is currently in the pre-production stage; sensors, modules, mechanical structures and services are being fabricated. The pixel modules assembled with ITkPix readout chips have been built to evaluate their performance and production rate. Irradiation campaigns were done to determine their thermal and electrical performance before and after irradiation. A new powering scheme — serial — will be employed in the ITk pixel detector, helping to reduce the material budget of the detector as well as power dissipation.

This contribution presents the status of the ITk-pixel project focusing on the lessons learned and the biggest challenges towards production. It will summarize the latest results on module assembly and testing. It will also present results from test beam campaigns.
