Published: June 2023

AbstractIn this paper, we report a novel electric-driven Janus nanomotor (JNMs) based on SPIONs nanoparticle decorated with chitosan (Cs) and sodium alginate (Na/Alg) using the Pickering emulsion method. The JNMs dispersed in aqueous media exhibit linear trajectories under DC electric field, and the driving force is attributed to the self-electro-osmotic mechanism and surface modifications. This study offers an approach to remotely control the motion modes of the JNMs, including start, stop, directional and programmable motion, which can be advantageous for various application scenarios. The diffusion coefficient and velocity of the JNMs were investigated through mean square displacement analysis for single particle of JNMs, both in distilled water and in the presence of different di and trivalent metal cations (Fe3+, Al3+, Ba2+, Ca2+ and Mg2+) as crosslinking agents, as well as monovalent salts (LiCl and KCl). The results revealed that the motion of JNMs was fastest in the presence of Fe3+ as crosslinker agent (about 7.2181 μm2/s) due to its higher charge than equimolar Na+ . Moreover, it was demonstrated that increasing the ionic strength led to relatively higher speeds of JNMs, as the solution polarity increased and, as a result, the driving force of electro-osmoesis enhanced.

AbstractOur urban systems and their underlying sub-systems are designed to deliver only a narrow set of human-centered services, with little or no accounting or understanding of how actions undercut the resilience of social-ecological-technological systems (SETS). Embracing a SETS resilience perspective creates opportunities for novel approaches to adaptation and transformation in complex environments. We: i) frame urban systems through a perspective shift from control to entanglement, ii) position SETS thinking as novel sensemaking to create repertoires of responses commensurate with environmental complexity (i.e., requisite complexity), and iii) describe modes of SETS sensemaking for urban system structures and functions as basic tenets to build requisite complexity. SETS sensemaking is an undertaking to reflexively bring sustained adaptation, anticipatory futures, loose-fit design, and co-governance into organizational decision-making and to help reimagine institutional structures and processes as entangled SETS.
Seasonal forecasting of subsurface marine heatwaves
Authors: McAdam Ronan , Masina Simona , Gualdi Silvio 
Published: June 2023

AbstractMarine heatwaves damage marine ecosystems and services, with effects identified mostly below the ocean surface. To create a truly user-relevant detection system, it is necessary to provide subsurface forecasts. Here, we demonstrate the feasibility of seasonal forecasting of subsurface marine heatwaves by using upper ocean heat content. We validate surface and subsurface events forecast by an operational dynamical seasonal forecasting system against satellite observations and an ocean reanalysis, respectively. We show that indicators of summer events (number of days, strongest intensity, and number of events) are predicted with greater skill than surface equivalents across much of the global ocean. We identify regions which do not display significant surface skill but could still benefit from accurate subsurface early warning tools (e.g., the mid-latitudes). The dynamical system used here outperforms a persistence model and is not widely influenced by warming trends, demonstrating the ability of the system to capture relevant subseasonal variability.
Volumetric interferometry for sparse 3D synthetic aperture radar with bistatic geometries
Authors: Welsh Richard , Andre Daniel , Finnis Mark 
Published: June 2023

AbstractSynthetic Aperture Radar (SAR) renderings in 3D provide additional target information when compared to 2D by separating out features overlaid in height. However, the required 2D SAR aperture, when Nyquist sampled, necessitates large scanning times that would be impractical for most realistic collections. This research has developed a novel volumetric approach to sparse aperture 3D SAR imaging, which is applicable to bistatic SAR near‐field geometries, a generalization of far‐field cases. This approach is first demonstrated in simulation and then applied to a measured scene containing a model vehicle target, producing sub‐Nyquist sampled 3D SAR renderings.
Security design for integrated communication and computation networks through cooperative cognitive radios
Authors: Hu Changjie , Li Quanzhong , Zhang Qi 
Published: June 2023

AbstractIn this letter, a novel integrated communication and computation framework is proposed through cooperative cognitive radios, which includes a communication primary network (PN) and a computing secondary network. Specifically, two primary communication users intend to exchange their confidential information with the relay assistance of cognitive access point (CAP), meanwhile, multiple sensors share the spectrum of PN to transmit their concurrent sensing data to CAP. The CAP is assumed to be a potential eavesdropper and to ensure the secure communication of primary users (PUs) and computational performance of the CAP, it is proposed to maximize the sum achievable secrecy rate of PUs by jointly designing the transmit precoding, relay beamforming matrix, transmit scaling factors and aggregation beamforming vector, while satisfying the constraint of the computational mean square error of the CAP. A weighted minimum mean square error (WMMSE)‐based block coordinate descent (BCD) algorithm is developed to solve the formulated problem, and simulation results are provided to validate the effectiveness of our proposed schemes.
Low‐light image enhancement for infrared and visible image fusion
Authors: Zhou Yiqiao , Xie Lisiqi , He Kangjian , Xu Dan , Tao Dapeng , Lin Xu 
Published: June 2023

AbstractInfrared and visible image fusion (IVIF) is an essential branch of image fusion, and enhancing the visible image of IVIF can significantly improve the fusion performance. However, many existing low‐light enhancement methods are unsuitable for the visible image enhancement of IVIF. In order to solve this problem, this paper proposes a new visible image enhancement method for IVIF. Firstly, the colour balance and contrast enhancement‐based self‐calibrated illumination estimation (CCSCE) is proposed to improve the input image's brightness, contrast, and colour information. Then, the method based on Mutually Guided Image Filtering (muGIF) is adopted to design a strategy to extract details adaptively from the original visible image, which can keep details without introducing additional noise effectively. Finally, the proposed visible image enhancement technique is used for IVIF tasks. In addition, the proposed method can be used for the visible image enhancement of IVIF and other low‐light images. Experiment results on different public datasets and IVIF demonstrate the authors’ method's superiority from both qualitative and quantitative comparisons. The authors’ code will be publicly available at https://github.com/yiqiao666/low‐light‐enhancement‐for‐IVIF/tree/master.
Dynamics analysis for DC transformers integration in hybrid AC‐DC power distribution networks
Authors: Mace Jules , Pillon Barcelos Renan , Dupont Max , Cervone Andrea , Dujic Drazen 
Published: June 2023

AbstractIn AC/DC power distributions networks, power converters are interfacing buses to ensure DC voltage regulation and power distribution. Active front ends are used between AC and DC buses and two typical control schemes that can be implemented are voltage regulation or power regulation. On the DC side, open‐loop operated DC transformers could be used between two DC buses to provide voltage adaptation, isolation and natural power flow. In this context, power flows and DC bus voltages in the power distribution network are dependent on the combined operation of the active front ends and the DC transformer. Mainly studied from a stability perspective, this interdependency between active front ends and DC transformers has lacked investigations in terms of dynamics. Fast dynamics is nevertheless important to operate optimally a network. In this paper, the assessment of the dynamic performance for distribution systems with DC transformers is performed for different mixes of voltage regulating and power regulating active front ends. The influence of DC line length and DC transformer power reversal method on the system is further investigated. A model of the system is proposed, validated experimentally and can be used to aid system level design and analysis of future DC systems.
Revisiting equilibrium condensation and rocky planet compositions
Authors: Timmermann Anina , Shan Yutong , Reiners Ansgar , Pack Andreas 
Published: June 2023

Context. The bulk composition of exoplanets cannot yet be directly observed. Equilibrium condensation simulations help us better understand the composition of the planets’ building blocks and their relation to the composition of their host star.
Aims. We introduce ECCOPLANETS, an open-source Python code that simulates condensation in the protoplanetary disk. Our aim is to analyse how well a simplistic model can reproduce the main characteristics of rocky planet formation. For this purpose, we revisited condensation temperatures (Tc) as a means to study disk chemistry, and explored their sensitivity to variations in pressure (p) and elemental abundance pattern. We also examined the bulk compositions of rocky planets around chemically diverse stars.
Methods. Our T-p-dependent chemical equilibrium model is based on a Gibbs free energy minimisation. We derived condensation temperatures for Solar System parameters with a simulation limited to the most common chemical species. We assessed their change (∆Tc) as a result of p-variation between 10−6 and 0.1 bar. To analyse the influence of the abundance pattern, key element ratios were varied, and the results were validated using solar neighbourhood stars. To derive the bulk compositions of planets, we explored three different planetary feeding-zone (FZ) models and compared their output to an external n-body simulation.
Results. Our model reproduces the external results well in all tests. For common planet-building elements, we derive a Tc that is within ±5 K of literature values, taking a wider spectrum of components into account. The Tc is sensitive to variations in p and the abundance pattern. For most elements, it rises with p and metallicity. The tested pressure range (10−6 − 0.1 bar) corresponds to ∆Tc ≈ +350 K, and for −0.3 ≤ [M/H] ≤ 0.4 we find ∆Tc ≈ +100 K. An increase in C/O from 0.1 to 0.7 results in a decrease of ∆Tc ≈ −100 K. Other element ratios are less influential. Dynamic planetary accretion can be emulated well with any FZ model. Their width can be adapted to reproduce gradual changes in planetary composition.
Overview of desorption parameters of volatile and complex organic molecules
Authors: Ligterink N. F. W. , Minissale M. 
Published: June 2023

Context. Many molecules observed in the interstellar medium are thought to result from the thermal desorption of ices. Parameters such as the desorption energy and pre-exponential frequency factor are essential in describing the desorption of molecules. Experimental determinations of these parameters are missing for many molecules, including those found in the interstellar medium.
Aims. The objective of this work is to expand the number of molecules for which desorption parameters are available, by collecting and re-analysing experimental temperature programmed desorption data that are present in the literature.
Methods. We used transition state theory (TST) in combination with the Redhead equation to determine the desorption parameters. Experimental data and molecular constants (e.g. mass, moment of inertia, etc.) were collected and given as input.
Results. Using the Redhead-TST method, the desorption parameters for 133 molecules were determined. The Redhead-TST method is found to provide reliable results that agree well with desorption parameters determined on the basis of more rigorous experimental methods. The importance of using accurately determined pre-exponential frequency factors to simulate desorption profiles is highlighted here. The large amount of data allows us to look for trends, with the most important being the relationship log10(v) = 2.65ln(m) + 8.07, where ν is the pre-exponential frequency factor and m is the mass of the molecule.
Conclusions. The data collected in this work allow for the thermal desorption of molecules to be modeled, with the aim of helping improve our understanding of changes in the chemical and elemental composition of interstellar environments.

Abstract
Background and study aims Traditional transoral outlet reduction (TORe) is a minimally invasive endoscopic approach focused on reducing the aperture of the gastrojejunal (GJ) anastomosis, while the tubular transoral outlet reduction (tTORe) consists of tabularization of the distal pouch utilizing an O-shape gastroplasty suturing pattern. The primary aim of this study was to compare short-term weight loss between TORe and tTORe.
Patients and methods Retrospective analysis of a prospectively maintained database was conducted at a tertiary care bariatric center of excellence. The study included patients with history of Roux-en-Y gastric bypass (RYGB) who had an endoscopic revision by TORe or tTORe and had follow-up data in their electronic medical record. The primary outcome was percent total body weight loss (%TBWL).
Results A total of 128 patients were included (tTORe=85, TORe=43). At 3 and 6 months, the tTORe and TORe cohorts presented similar %TBWL (3 months: 8.5±4.9 vs. 7.3±6.0, P = 0.27 and 6 months: 8.1±7.4 vs. 6.8±5.6, P = 0.44). At 9 months, there was a trend toward greater weight loss in the tTORe cohort (9.7±8.6% vs. 5.1±6.8%, P = 0.053). At 12 months, the %TBWL was significantly higher in the tubularization group compared to the standard group (8.2±10.8 vs. 2.3±7.3%, P = 0.01). Procedure time was significantly different between both groups (60.5 vs. 53.4 minutes, P = 0.03). The adverse events rate was similar between groups (8.2% vs. 7.0% for tTORe and TORe, respectively, P = 0.61).
Conclusions The tTORe enhances efficacy and durability of the standard procedure without adding significant procedure-related risks.

Abstract
Objectives Direct intrahepatic portosystemic shunt (DIPS) stent placement is an effective treatment for patients with Budd-Chiari syndrome (BCS); however, thrombotic occlusion of DIPS stent remains a cause of concern. The purpose of this study is to describe a novel technique of balloon-occluded-thrombolysis (BOT) for occluded DIPS stent, and compare it with the conventional catheter-directed-thrombolysis (CDT).
Methods In this retrospective study, the hospital database was searched for BCS patients who underwent DIPS revision for thrombotic stent occlusion between January 2015 and February 2021. Patients were divided into CDT group and BOT group. The groups were compared for technical success, total dose of thrombolytic agent administered, duration of hospital stay, and primary assisted stent patency rates at 1- and 6-month follow-up.
Results CDT was performed in 12 patients, whereas 21 patients underwent BOT. Complete recanalization was achieved in 66.7% (8 of 12) patients of CDT group as compared to 81% (17 of 21) patients of BOT group (nonsignificant difference, p = 0.420). BOT group had a short hospital stay (1.8 ± 0.7 vs. 3.5 ± 1.0 days) and required less dose of thrombolytic agent ([2.2 ± 0.4]x105 IU versus [8.3 ± 2.9]x105 IU of urokinase) as compared to the CDT group and both differences were statistically significant (p < 0.001). Further, 6-month patency rate was higher in BOT group as compared to CDT group (p = 0.024).
Conclusion The novel BOT technique of DIPS revision allows longer contact time of thrombolytic agent with the thrombi within the occluded stent. This helps in achieving fast recanalization of thrombosed DIPS stent with a significantly less dose of thrombolytic agent required, thus reducing the risk of systemic complications associated with thrombolytic administration.

Published: June 2023

Abstract
Background Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 and was first recorded in December 2019. COVID-19 became a pandemic involving almost all countries, including Japan. We evaluated the tolerability and safety of coronavirus vaccines in terms of seizures in adolescents and young adults with epilepsy (AYAWE).
Methods We administered a questionnaire to AYAWE who visited the pediatrics departments of Hiroshima University Hospital, Hiroshima Prefectural Hospital, and Hiroshima City Funairi Citizens Hospital in January and February 2022. Tolerability and safety after immunization were assessed.
Results In total, 114 vaccinations were delivered to 57 AYAWE aged 12 to 25 years (mean, 15 ± 3.1 years). Fifty-two (91.2%) experienced more than or equal to 1 adverse event postvaccination. The most commonly reported adverse events were fever (dose 1, 33.3%; dose 2, 73.7%) and fatigue (dose 1, 24.6%; dose 2, 50.9%). The incidences of headache (5.2 vs. 21.0%, p = 0.024), fever (33.3 vs. 73.7%, p < 0.001), and fatigue (24.6 vs. 50.9%, p = 0.004) differed significantly between the first and second doses. Only 5.2% of patients experienced transient seizure worsening, and only one patient reported a change in seizure semiology.
Conclusion COVID-19 vaccines were well-tolerated in our cohort. The vaccines did not affect the number or manifestations of seizures. Similar to other illnesses, vaccination for COVID-19 can be administered to AYAWE without worsening their seizures.
High-frequency crossover from vortex-mass enhancement to pinning
Authors: Lipavský Pavel , Lin Pei-Jen 
Published: June 2023

Abstract
Starting from lattice dynamics, Ginzburg Landau Theory is used to study phonon contributions to the effective vortex mass of a moving Abrikosov lattice driven by a small driving force, in this case circularly polarized light. A general expression is obtained of dynamical additional mass, which is capable of including both acoustic and optical phonon contributions. At the level of linear response, this frequency-dependent mass increases with driving frequency. After reaching a maximum at the frequency corresponding to the eigenvalue of the wave vector matching the coherence length, the mass begins to decrease, and eventually changes sign crossing to an effective pinning regime at high frequency. These calculations are applied to experimental results of YBCO (Teasř et al 2021 Sci. Rep.
11 21708).
Reassessing lead protective garment assessment using ICRP 103 tissue weighting factors
Authors: Brewer Joan M , Hammerstrom Kevin , Bjarnason Thorarin A 
Published: June 2023

Abstract
Lead protective garments worn by medical staff in the presence of x-rays develop defects over time. This work proposes a novel method of assessing the protective efficacy of the garments as defects develop. The proposed method applies updated radiobiology data from ICRP 103. This work applied the as low as reasonably achievable principle to devise a formula through which a maximum allowed defect area in lead protective garments can be calculated. This formula depends on the cross-sectional areas (

A

) and ICRP 103 tissue weighting factors (

w

t

) of the most radiosensitive and overlapping organs protected by the garment, the maximum allowed additional effective dose to the garment wearer due to the defects (

d

), and the unattenuated absorbed dose at the surface of the garment (

D

). The maximum allowed defect areas are separated into three regions: above the waist, below the waist, and thyroid. To be conservative, it was assumed that

D

= 50 mGy yr−1, and

d

= 0.3 mSv yr−1. Also conservatively, transmission was assumed to be 0%, as employing a non-zero transmission factor would increase the maximum allowed defect area. Maximum allowed defect areas were as follows: 370 mm2 for above the waist, 37 mm2 for below the waist, and 279 mm2 for the thyroid. These values can be compared to commonly published values which are 670 mm2 for an apron, 15 mm2 over the gonads, and 11–20 mm2 for the thyroid. The proposed method for lead protective garment assessment is highly adaptable as values can be adjusted as radiobiology data are updated, and as values such as radiation dose limits vary across jurisdictions. Future works will include collection of data for unattenuated dose to apron (

D

) as it varies across professions, so that garments may be allowed different defect areas if relegated to individuals of specific professions.
