Context. SPHERE, operating at the VLT since 2014, is currently one of the high-contrast instruments with a higher performance. Its adaptive optics system, known as SAXO, will be upgraded to SAXO+, which features the addition of a second stage of adaptive optics. This stage will use a near-infrared pyramid wavefront sensor to record images of fainter exoplanets around redder stars.
Aims. In this work, we compare the performance of SAXO and SAXO+. We look for the optimal values of the key system parameters of SAXO+ for various science cases and turbulence conditions.
Methods. We performed numerical simulations using COMPASS, an end-to-end adaptive optics simulation tool. We simulated perfect coronagraph images of an on-axis point source, and we minimized the residual starlight intensity between 3 and 5 λ/D as a performance criterion. The explored parameter space includes science cases (described by magnitude in G and J bands), turbulence conditions (seeing and coherence time), and key system parameters (first and second stage gains, first and second stage frequencies, pyramid modulation radius, pyramid modal gains optimization).
Results. In every science case and turbulence condition, SAXO+ reduces the residual starlight intensity inside the correction zone of the second stage by a factor of ten compared to SAXO. The optimal first stage gain is lower for SAXO+ than for SAXO alone. We quantified the gain in performance of SAXO+ when changing the second stage frequency from 2 to 3 kHz, and we conclude that 2 kHz may be sufficient for most realistic conditions. We give the optimal first stage gain as well as the first and second stage frequencies for every seeing, coherence time, and science case. Finally, we find that a 2 λWFS/D pyramid modulation radius is a good trade-off between performance and robustness against varying turbulence conditions.
Conclusions. This study shows that the future SAXO+ system will outperform the current SAXO system in all studied cases.

Significance of the sFlt-1/PlGF Ratio in Certain Cohorts – What Needs to be Considered?

Published: July 2024

AbstractThe sFlt-1/PlGF ratio is an established tool in clinical practice, where it is part of a diagnostic algorithm and informs the prognosis of preeclampsia (PE). Maternal and gestational comorbidities can affect the performance of the sFlt-1/PlGF ratio and its constituent elements, and a good understanding of the potential pitfalls is required. The objective of this paper was to provide a current narrative review of the literature on the diagnostic and predictive performance of the sFlt-1/PlGF ratio in specific patient cohorts. Potential factors which can negatively affect the clinical interpretability and applicability of the sFlt-1/PlGF ratio include chronic kidney disease, twin pregnancy, and maternal obesity. Pathophysiological mechanisms related to these factors and disorders can result in different concentrations of sFlt-1 and/or PlGF in maternal blood, meaning that the use of standard cut-off values in specific cohorts can lead to errors. To what extent the cut-off values
should be adapted in certain patient cohorts can only be clarified in large prospective cohort studies. This applies to the use of the ratio both for diagnosis and prognosis.

ZusammenfassungUm zu erklären, warum Menschen an Unglücksorten zusehen, werden bisher auf theoretischer Basis biologische, individual- und sozialpsychologische Motive herangezogen. Empirische Untersuchungen in rettungsmedizinischen Kontexten fehlen bislang.In diesem Artikel werden anderen zugeschriebene Beweggründe für das Zuschauen an Einsatzorten erhoben. Zusätzlich wird ermittelt, wie viele Personen qua Selbstauskunft bereits bei Rettungsmaßnahmen zugesehen haben und was die eigenen Beweggründe dafür waren. Diese Beweggründe werden gegenübergestellt und mit bestehenden theoretischen Annahmen abgeglichen.Studie 1 – repräsentative Bevölkerungsbefragungen (t1 n = 1032, t2 n = 1012) im Abstand eines Jahres zu eigenem Zuschauen und Beweggründen bzw. jenen anderer. Studie 2 – Gelegenheitsstichprobe (n = 40) zur Bewertung der in Studie 1 ermittelten Beweggründe.Die Mehrheit der Befragten verneint, selbst an Einsatzorten zugesehen zu haben (t1: 80,1%, t2: 86,9%). Zu t2 berichten 131 Personen (12,95%) von eigenem Zuschauen und nennen ihre eigenen Beweggründe dafür. Insgesamt entsprechen diese weitestgehend den in der notfallpsychologischen Literatur postulierten Motiven. Die Beweggründe anderer werden überwiegend dispositional und abwertend ausdrückt. Dagegen werden eigene Beweggründe stärker selbstwertdienlich und situational formuliert. Die Daten werden vor dem Hintergrund des fundamentalen Attributionsfehlers diskutiert.
Ablation of Primary and Recurrent Thyroid Cancer: Current and Future Perspectives
Authors: Freeman Toliver , Pena Olivia , Sag Alan Alper , Young Shamar 
Published: July 2024

AbstractThyroid cancer is the most common endocrine malignancy, and its incidence is increasing, driven in part by the advent of ultrasound, and subsequent increased detection of small, early thyroid cancers. Yet even for small tumors, thyroidectomy with lymph node dissection remains standard of care. Specific to well-differentiated thyroid cancer, surgery has come under scrutiny as a possible overtreatment, in light of stable and favorable survival rates even as guidelines have allowed fewer radical resections and lymph node dissections over time. Moreover, thyroid cancer unfortunately has a known recurrence rate regardless of therapy, and surgical re-intervention for local structural recurrence is eventually limited by scar. Radioactive iodine therapy, another accepted treatment, is minimally invasive but can only treat patients with iodine-avid tumors. For all of these reasons, image-guided thermal ablation has emerged as a valuable complementary tool as a thyroid-sparing, parathyroid-sparing, voice-sparing, repeatable, minimally invasive outpatient focal therapy for both primary and recurrent well-differentiated thyroid cancers. However, the data are still evolving, and this represents a new patient cohort for some interventional radiologists. Therefore, the goal of this review is to discuss the technique and evidence for ablation of patients with thyroid cancer.
An Interventional Radiologist's Guide to Lung Cancer
Authors: Fish Adam G. , Madoff David C. 
Published: July 2024

AbstractLung cancer continues to be the third leading cause of cancer and the leading cause of cancer deaths. As the field of interventional oncology continues to grow, interventional radiologists are increasingly treating lung cancer patients. Involvement begins with tissue diagnosis for which biomarkers and immunohistochemistry are used to guide selective and advanced medical therapies. An interventional radiologist must be aware of the rationale behind tissue diagnosis and techniques to minimize biopsy complications. Staging is an important part of tumor board conversations and drives treatment pathways. Surgical therapy remains the gold standard for early-stage disease but with an aging population the need for less invasive treatments such as radiation therapy and ablation continue to grow. The interventionalist must be aware of the indications, techniques, and pre- and posttherapy managements for percutaneous ablation. Endovascular therapy is broadly divided into therapeutic treatment of lung cancer, which is gaining traction, and treatment of lung cancer complications such as hemoptysis. This review aims to provide a good basis for interventional radiologists treating lung cancer patients.
Image-Guided Ablation of Renal Masses: Challenges to Produce High-Quality Evidence and Future Directions

Published: July 2024

AbstractImage-guided ablation (IGA) is a rapidly developing field in interventional oncology. There is some evidence suggesting IGA's non-inferiority compared with partial or radical nephrectomy for the treatment of small renal masses (SRM). However, these are mostly limited to retrospective cohort studies. This review article outlines the evidence comparing IGA to partial nephrectomy by collating the different survival measures and evaluates the challenges of producing clinical trials and high-quality evidence. The main challenges are due to the heterogeneity of SRM, patient selection bias, unstandardized endpoint and outcomes, and the lack of global practice standards. Despite the evidence thus far demonstrating that IGA stands as a non-inferior treatment modality for SRMs, exhibiting favorable short- and long-term outcomes, further robust research is needed to integrate ablation techniques into routine clinical practice with a multidisciplinary approach. There is emerging evidence that suggests randomized controlled trial in SRMs is possible, and technologies such as histotripsy as well as artificial intelligence are used in IGA.

AbstractSince no uniform treatment protocol for pancreatic irreversible electroporation (IRE) exists, the heterogeneity throughout literature complicates the comparison of results. To reach agreement among experts, a consensus study was performed. Eleven experts, recruited according to predefined criteria regarding previous IRE publications, participated anonymously in three rounds of questionnaires according to a modified Delphi technique. Consensus was defined as having reached ≥80% agreement. Response rates were 100, 64, and 64% in rounds 1 to 3, respectively; consensus was reached in 93%. Pancreatic IRE should be considered for stage III pancreatic cancer and inoperable recurrent disease after previous local treatment. Absolute contraindications are ventricular arrhythmias, implantable stimulation devices, congestive heart failure NYHA class 4, and severe ascites. The inter-electrode distance should be 10 to 20 mm and the exposure length should be 15 mm. After 10 test pulses, 90 treatment pulses of 1,500 V/cm should be delivered continuously, with a 90-µs pulse length. The first postprocedural contrast-enhanced computed tomography should take place 1 month post-IRE, and then every 3 months. This article provides expert recommendations regarding patient selection, procedure, and follow-up for IRE treatment in pancreatic malignancies through a modified Delphi consensus study. Future studies should define the maximum tumor diameter, response evaluation criteria, and the optimal number of preoperative FOLFIRINOX cycles.

regularizations, and establish the global convergence and linear convergence rate of the proximal gradient algorithm under some mild conditions. More importantly, we propose two types of proximal gradient algorithms with the truncation technique and the continuation technique, respectively, and establish their convergence to the ground true joint sparse solution within a tolerance relevant to the noise level and the recovery bound under the assumption of restricted isometry property. In the aspect of application, we develop a novel method, based on joint sparse optimization with lower-order regularization and proximal gradient algorithm, to infer the master transcription factors for cell fate conversion, which is a powerful tool in developmental biology and regenerative medicine. Numerical results indicate that the novel method facilitates fast identification of master transcription factors, give raise to the possibility of higher successful conversion rate and in the hope of reducing biological experimental cost.

Abstract
The work reports a novel application of the interacting boson model in light-mass region around 48Ca, that takes into account intruder states and configuration mixing. The model is shown to provide a reasonable description of the observed low-lying yrast and yrare states of the N = 28 even–even isotones from Si to Fe, and even–even Ca isotopes. The nature of

states is addressed in terms of the competition between spherical and deformed intruder configurations, and the rigidity of the N = 28 shell gap is tested, particularly for 44S. The

isomer in 44S is shown to arise from a weak mixing between the two configurations and called as shape isomer. The unresolved low-lying spectra in 46Ar is also approached using the core-excitations across N = 28 shell. The SU(3) structure in 42Si is supported by the present calculation. The nearly spherical nature of 50Ti, 52Cr, 54Fe and 42,44,46Ca isotopes is found, while the core excitations are found to be essential for the description of yrare states. Shell model calculation is also performed for comparison.

Abstract
This paper introduces the 3D-ElectroZip Touch, a multi-directional force feedback device developed using dielectrophoretic liquid zipping actuation. The device is designed to stimulate the sense of normal and shear forces by moving in vertical and multiple horizontal directions. Its performance, including displacement, force, and actuation time has been characterized under input voltages from 6 kV to 9 kV, demonstrating a displacement range of 5–11 mm, force range of 0.05 N to 0.22 N, power output ranges from 0.08 W to 0.077 W, and maximum energy efficiency of 72%. The 3D-ElectroZip Touch shows a quick response to the input signal, moving its contact panel by 1.1 mm in 70 ms (36.5% of human reaction time) at 9 kV. Comparing its basic characteristics with the skin sensitivity and the lightweight, compliance, and scalability of the 3D-ElectroZip Touch technology show its high potential to be exploited in tactile displays and wearable haptic feedback devices.

Published: July 2024

Abstract
Multi-valued logic (MVL) extends binary logic by providing a framework to represent complex systems with more than two truth values. MVL was introduced to confront the enormous interconnect issue associated with the binary logic in implementing the presnt day complex nanoelectronic architectures. This paper delves into the circuit design, computational aspects, and practical applications of the quaternary logic system, which is a type of MVL with four truth values. The multi-threshold property of carbon nanotube field-effect-transistors (CNTFETs), combined with the ability of resistive random-access memory (RRAM) to store multiple resistance values, has enabled the design of quaternary logic gates and arithmetic circuits. A new CNTFET-based design architecture has been proposed to implement the quaternary logic compatible with the existing technologies. Quaternary logic gates such as inverter, NAND, and NOR, and quaternary arithmetic circuits including decoder, half adder, and multiplier have been designed. The power-delay-product (PDP) of the proposed quaternary inverter, NAND, NOR, half adder, and multiplier is 62.38%, 93.4%, 80.29%, 14.79%, and 20% less than the least PDP of the quaternary designs under consideration. The static power reduction due to the effecciency of the design architecture and high OFF state resistance offered by integrating RRAM into the logic design was explored.The proposed circuits have been subject to various types of parameter variations to validate thir proper functionality in presence of these variations.
Modified gravity: gravitationally coupled bodies displace the center of mass of each other
Authors: Mutuku Kieti 
Published: July 2024

Abstract
Empirical observations have revealed that Newtonian dynamics do not correspond with the amount of visible matter in galactic scales. This imply that there is a vast amount of unseen matter or failure of the theory of gravity in galactic scales or something else. This paper demonstrates that gravitationally coupled bodies offset the center of mass of each other from either very center. Gravitational interaction among particles composing gravitationally coupled bodies lead to displacement of their (bodies) centers of mass towards each other. The magnitude of displacement of the center of mass of a body depends on its mass density, separation distance between the bodies, and mass of the body exerting the gravitational pull. This phenomenon reduces the separation distance between the bodies, thus increasing the net gravitational force between them (bodies).
HQC-MCDCNN: a novel hybrid quantum–classical multi-path denoising convolutional neural network

Published: July 2024

Abstract
Image denoising is a longstanding and enduring visual problem, and with the continuous rise of quantum computing in the field of machine learning, its role in image processing has become increasingly important. This paper introduces for the first time the use of multiscale variational quantum circuits in the field of image denoising, aiming to enhance the performance of classical convolutional neural networks and explore the potential advantages of combining quantum and classical approaches. In this work, we propose a novel Hybrid Quantum-Classical Multi-Path Denoising Convolutional Neural Network, abbreviated as HQC-MCDCNN. The HQC-MCDCNN is composed of a hybrid of quantum and classical elements, with the quantum part using multiscale variational quantum circuits instead of classical convolutional layers for feature extraction, and the classical part employing a newly designed multi-path denoising convolutional neural network for supervised learning. Together, these components synergistically achieve image denoising. It is worth noting that this paper aims to build readers’ intuition for quantum computing, presenting all internal details of this work with rich images and visualizations. To demonstrate the denoising capability of HQC-MCDCNN, we conducted rigorous comparative experiments. Due to the constraints of Noisy Intermediate-Scale Quantum (NISQ) devices and the limited number of quantum bits, the experiments were based on the MNIST and Fashion-MNIST datasets with varying degrees of noise (noise factors ranging from 0.3 to 0.7), employing a 6-fold stratified sampling strategy for cross-validation. The experimental results indicate that HQC-MCDCNN is promising across all evaluation metrics, particularly outperforming other models by 56.5% in the average UIQ index. This suggests that our hybrid model exhibits outstanding feature extraction capabilities and excellent denoising performance, providing a promising path for addressing image denoising challenges.
Reconfigurable terahertz stretchable spoof surface plasmon polariton waveguide for filter applications
Authors: Shi Xiao Gang , Xue Zheng Hui , Xie Yi , Jiang Jian Wei , Zhang Wei , Le Zhang Qing 
Published: July 2024

Abstract
In this paper, a reconfigurable terahertz spoof surface plasmon polariton (SPP) waveguide is proposed on a stretchable polydimethylsiloxane (PDMS) substrate. The SPP unit incorporates a folded stub and a conventional V-shaped SPP groove, enhancing the equivalent capacitance and consequently reducing the cutoff frequency. The cutoff frequency of the proposed SPP unit can be tuned from 285 to 390 GHz with stretchable factors of 1 ∼ 1.2, thereby achieving a reconfigurable operating frequency. The horizontal dimension of the proposed SPP waveguide can be tuned from 6.36 mm to 7.12 mm. Moreover, the SPP waveguide can generate transmission continuous phase shifts of −30°, −60°, −90°, and −120° with stretchable factors of 1.05, 1.1, 1.15, and 1.2, respectively, in the 150–190 GHz band. Applying the characteristic mode theory, a split ring resonator (SRR) functions as the equivalent magnetic dipole, which remains unaffected by stretchable deformation. When loaded with four SRR cells, the proposed SPP waveguide generates a tunable passband with a fixed notched frequency at 193 GHz. Another stretchable SPP resonator serves as the equivalent electric dipole, operating from 284 GHz to 256 GHz in 1∼1.2 stretchable states. By loading three SPP resonators, the SPP waveguide can achieve a passband for the initial state, and a tunable stopband is introduced under 1.1 and 1.2 stretchable states. The proposed stretchable method provides a promising solution for planar terahertz components and systems with reconfigurable functions.
