Context.Galactic cosmic rays (GCRs) and solar particles with energies greater than tens of MeV penetrate spacecraft and instruments hosted aboard space missions. The Solar Orbiter Metis coronagraph is aimed at observing the solar corona in both visible (VL) and ultraviolet (UV) light. Particle tracks are observed in the Metis images of the corona. An algorithm has been implemented in the Metis processing electronics to detect the VL image pixels crossed by cosmic rays. This algorithm was initially enabled for the VL instrument only, since the process of separating the particle tracks in the UV images has proven to be very challenging.Aims.We study the impact of the overall bulk of particles of galactic and solar origin on the Metis coronagraph images. We discuss the effects of the increasing solar activity after the Solar Orbiter mission launch on the secondary particle production in the spacecraft.Methods.We compared Monte Carlo simulations of GCRs crossing or interacting in the Metis VL CMOS sensor to observations gathered in 2020 and 2022. We also evaluated the impact of solar energetic particle events of different intensities on the Metis images.Results.The study of the role of abundant and rare cosmic rays in firing pixels in the Metis VL images of the corona allows us to estimate the efficiency of the algorithm applied for cosmic-ray track removal from the images and to demonstrate that the instrument performance had remained unchanged during the first two years of the Solar Orbiter operations. The outcome of this work can be used to estimate the Solar Orbiter instrument’s deep charging and the order of magnitude for energetic particles crossing the images of Metis and other instruments such as STIX and EUI.

Published: July 2023

Abstract
Background Innovations in medical technologies have impacted surgery sustainably in the last decades. To enable and further improve microsurgical outcomes, different loupes and optic-based microscopes have been proposed in recent years. In amputation surgery continuous progress and prosthetic developments have provided amputees with an improved degree of function and quality of life.Herein, we present a 17-year-old patient who suffered a traumatic loss of the left upper limb and underwent target muscle reinnervation surgery facilitated by a three-dimensional (3D) robotic exoscope system.
Methods The rerouting of the distal ends of the arm nerves (TMR) was performed in the upper limb of a traumatic transhumeral amputee patient using a 3D robotic exoscope system (RS, RoboticScope, BHS Technologies, Innsbruck, Austria). Perioperative data was collected and compared to standard. Users' perspective evaluation of the system during the surgical procedure was done using a 5-point Likert scale.
Results Operation time was 311 minutes, the robotic system was used for 101 minutes. Overall users' evaluation revealed a 4.5 for the selected items on the Likert scale. The evaluation showed similar results in the evaluation of the system by the main and assistant surgeons. No special training was required beforehand. The bimanual control allowed for improved personal freedom in the surgical field at a comfortable position. The imaging of colors will need future improvements until an authentic representation of in situ structures is achieved.
Conclusion Major advantages of a robotic scope 3D exoscope system are improved image quality, ergonomic position, and increased accessibility in a wider operating field due to system-implied features. Another benefit is digital documentation and simultaneous education through the possibility of capturing images and videos, as well as easy transportation in between operating rooms without risk to harm the vulnerable optic. Digital microscopes are still associated with high acquisition costs, and they are not yet implemented as standard of care due to limited experience.
Combined Endoscopy–Laparoscopy Surgery: When and How to Utilize This Tool
Authors: Wlodarczyk Jordan , Gupta Abhinav , Lee Sang W. 
Published: July 2023

AbstractCombined endoscopic and laparoscopic surgery (CELS) has been used to resect colon polyps since the 1990s. These colon-sparing techniques, however, have not yet been widely adopted. With the evolution of technology in both diagnosing and treating colon cancer, colorectal surgeons should strive for a diverse and complete armamentarium through which they can best serve their patients. In this article, we hope to provide clarity on CELS by discussing three topics: (1) the history and fruition of CELS; (2) the techniques involved in CELS; and (3) the utility of CELS within different clinical scenarios. Our goal is to educate readers and stimulate consideration of CELS in select patients who might benefit greatly from these techniques.

AbstractVarious synthetic applications of iron-based Lewis acid complexes are presented through their most noteworthy and groundbreaking applications in asymmetric catalysis. The iron Lewis acids are organized according to their structure, and then their reactivity. It has been reported that various chiral iron Lewis acids can be used in a broad range of synthetic transformations. Diverse categories of chiral ligands are used in asymmetric catalysis using chiral iron complexes, including N,N′-dioxides, bipyridines, oxazolines, Schiff bases, salen/salan-type structures, and aminopyridines.

Diffusive spatial movement with memory in an advective environment
Authors: Zhang Hua , Wang Hao , Song Yongli , Wei Junjie 
Published: July 2023

Abstract
The movements of species in a river are driven by random diffusion, unidirectional water flow, and cognitive judgement with spatial memory. In this paper, we formulate a reaction–diffusion–advection model with memory-based diffusion and homogeneous Dirichlet boundary conditions. The existence of a nonconstant positive steady state is proven. We obtain the linear stability of the steady state by analysing the eigenvalues of the associated linear operator: the nonconstant steady state can always be linearly stable regardless of the memory delay, while the model can also possess Hopf bifurcation as the memory delay varies. Moreover, theoretical and numerical results show that large advection annihilates oscillation patterns and drives the species to concentrate downstream.
Noise-induced dynamics and photon statistics in bimodal quantum-dot micropillar lasers

Published: July 2023

Abstract
Emission characteristics of quantum-dot micropillar lasers (QDMLs) are located at the intersection of nanophotonics and nonlinear dynamics, which provides an ideal platform for studying the optical interface between classical and quantum systems. In this work, a noise-induced bimodal QDML with orthogonal dual-mode outputs is modeled, and nonlinear dynamics, stochastic mode jumping and quantum statistics with the variation of stochastic noise intensity are investigated. Noise-induced effects lead to the emergence of two intensity bifurcation points for the strong and the weak mode, and the maximum output power of the strong mode becomes larger as the noise intensity increases. The anti-correlation of the two modes reaches the maximum at the second intensity bifurcation point. The dual-mode stochastic jumping frequency and effective bandwidth can exceed 100 GHz and 30 GHz under the noise-induced effect. Moreover, the noise-induced photon correlations of both modes simultaneously exhibit super-thermal bunching effects (

) of both modes is observed over a wide range of noise intensities and injection currents. In the presence of the noise-induced effect, the photon number distribution of the strong or the weak mode is a mixture of Bose–Einstein and Poisson distributions. As the noise intensity increases, the photon number distribution of the strong mode is dominated by the Bose–Einstein distribution, and the proportion of the Poisson distribution is increased in the high injection current region, while that of the weak mode is reduced. Our results contribute to the development preparation of super-bunching quantum integrated light sources for improving the spatiotemporal resolution of quantum sensing measurements and enhancing the security of optical communication.
Pseudanthia in angiosperms: a review
Authors: Baczyński Jakub , Claßen-Bockhoff Regine 
Published: July 2023

AbstractBackgroundPseudanthia or ‘false flowers’ are multiflowered units that resemble solitary flowers in form and function. Over the last century the term ‘pseudanthium’ has been applied to a wide array of morphologically divergent blossoms, ranging from those with easily noticeable florets to derived, reduced units in which individual flowers become almost indistinguishable. Although initially admired mostly by botanists, the diversity and widespread distribution of pseudanthia across angiosperms has already made them a fascinating topic for evolutionary and developmental comparative studies.ScopeThis review synthesizes historical and current concepts on the biology of pseudanthia. Our first aim is to establish a clear, operational definition of pseudanthium and disentangle common terminological misconceptions surrounding that term. Our second aim is to summarize knowledge of the morphological and developmental diversity of pseudanthia and embed it within a modern phylogenetic framework. Lastly, we want to provide a comprehensive overview on the evolution and ecological importance of pseudanthia and outline perspectives for future studies.ConclusionsThe understanding of pseudanthia has changed multiple times and reflects three different interpretations of their ‘flower-like’ qualities: developmental (similarity in structure), figural (similarity in form and function) and phylogenetic (homology between angiosperm flowers and monoecious reproductive shoots in gymnosperms). Here, we propose to narrow the term pseudanthium to multiflowered blossoms resembling zoophilous flowers in form, i.e. in being structurally subdivided in a showy periphery and a reproductive centre. According to this definition, pseudanthia sensu stricto evolved independently in at least 41 angiosperm families. The recurrent acquisition of pseudanthia sensu stricto in all major lineages of flowering plants indicates repeated interactions between developmental constraints (smallness of flowers, meristematic conditions) and selective pressures, such as demands of pollinators and/or environmental conditions.
Improved electrochemical properties of graphite electrodes incubated with iron powders in rice-paddy fields boost power outputs from microbial fuel cells

Published: July 2023

ABSTRACT
Studies have shown that the supplementation of anode-surrounding soil with zero-valent iron (ZVI) boosts power outputs from rice paddy-field microbial fuel cells (RP-MFCs). In order to understand mechanisms by which ZVI boosts outputs from RP-MFCs, the present study operated RP-MFCs with and without ZVI, and compositions of anode-associated bacteria and electrochemical properties of graphite anodes were analyzed after 3-month operation. Metabarcoding using 16S rRNA gene fragments showed that bacterial compositions did not largely differ among these RP-MFCs. Cyclic voltammetry showed improved electrochemical properties of anodes recovered from ZVI-supplemented RP-MFCs, and this was attributed to the adhesion of iron-oxide films onto graphite surfaces. Bioelectrochemical devices equipped with graphite anodes recovered from ZVI-supplemented RP-MFCs generated higher currents than those with fresh graphite anodes. These results suggest that ZVI is oxidized to iron oxides in paddy-field soil and adheres onto graphite anodes, resulting in the boost of power outputs from RP-MFCs.

Abstract

Background
Transcutaneous electrical nerve stimulation (TENS) is an established method for pain relief. But electrical TENS currents are also a source of electromagnetic interference (EMI). Thus, TENS is considered to be contraindicated in implantable cardioverter-defibrillator (ICD) patients. However, data might be outdated due to considerable advances in ICD and cardiac resynchronization therapy (CRT) filtering and noise protection algorithm technologies. The aim of this pilot safety study was to re-evaluate the safety of TENS in patients with modern ICDs.

Methods and results
One hundred and seven patients equipped with 55 different models of ICD/CRT with defibrillators from 4 manufacturers underwent a standardized test protocol including TENS at the cervical spine and the thorax, at 2 stimulation modes—high-frequency TENS (80 Hz) and burst-mode TENS (2 Hz). Potential interference monitoring included continuous documentation of ECG Lead II, intracardiac electrograms and the marker channel. Electromagnetic interference was detected in 17 of 107 patients (15.9%). Most frequent were: interpretations as a premature ventricular beats (VS/S) in 15 patients (14%), noise reversion in 5 (4.6%) which resulted in temporary asynchronous pacing in 3 (2.8%), interpretation as ventricular tachycardia/ventricular fibrillation in 2 (1.9%), and premature atrial beat in 2 (1.9%) patients. Electromagnetic interference occurrence was influenced by position (chest, P &lt; 0.01), higher current intensity (P &lt; 0.01), and manufacturer (P = 0.012).

Conclusion
Overall, only intermittent and minor EMI were detected. Prior to the use of TENS in patients with ICDs, they should undergo testing under the supervision of a cardiac device specialist.

Abstract
IL-13 signaling polarizes macrophages to an M2 alternatively activated phenotype, which regulates tissue repair and anti-inflammatory responses. However, an excessive activation of this pathway leads to severe pathologies, such as allergic airway inflammation and asthma. In this work, we identified NOTCH4 receptor as an important modulator of M2 macrophage activation. We show that the expression of NOTCH4 is induced by IL-13, mediated by Janus kinases and AP1 activity, probably mediated by the IL-13Rα1 and IL-13Rα2 signaling pathway. Furthermore, we demonstrate an important role for NOTCH4 signaling in the IL-13 induced gene expression program in macrophages, including various genes that contribute to pathogenesis of the airways in asthma, such as ARG1, YM1, CCL24, IL-10, or CD-163. We also demonstrate that NOTCH4 signaling modulates IL-13-induced gene expression by increasing IRF4 activity, mediated, at least in part, by the expression of the histone H3K27me3 demethylase JMJD3, and by increasing AP1-dependent transcription. In summary, our results provide evidence for an important role of NOTCH4 signaling in alternative activation of macrophages by IL-13 and suggest that NOTCH4 may contribute to the increased severity of lesions in M2 inflammatory responses, such as allergic asthma, which points to NOTCH4 as a potential new target for the treatment of these pathologies.
Transnational Market Navigation: Living and Consuming across Borders
Authors: Sharifonnasabi Zahra , Mimoun Laetitia , Bardhi Fleura 
Published: July 2023

Abstract
Prior research has investigated global mobility through the lenses of consumer acculturation, identity, and possessions with a focus on consumers’ socialization and identity management in the host consumer culture. It has neglected, however, the ways that globally mobile consumers simultaneously navigate the multiple, cross-border markets in which they are embedded. We adopt the social network perspective to investigate the transnational consumer lifestyles of people who live and consume simultaneously in two or more countries and sustain multiple relationships of a diverse nature (e.g., market, social, financial, professional) across borders. Through a qualitative study, we dimensionalize the transnational social space inhabited by transnational consumers and demonstrate how it shapes their consumption. We introduce the concept of transnational market navigation, defined as the process of strategically and pragmatically selecting and leveraging social networks to engage simultaneously with multiple cross-border markets. We identify three transnational market navigation strategies: clustering consumption, embracing commercial lock-ins, and developing cluster-based competency. By mobilizing a network perspective to examine consumption in global mobility, we show that globally mobile consumers are also motivated by ways of being (the actual social and commercial relationships and consumption practices with which consumers engage), in addition to the identities associated with their consumption.

Published: July 2023

ABSTRACT
We present the results of our new H i observations for the nearby galaxy NGC 4449 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). More diffuse H i gas was detected by FAST compared with previous studies. The measured extent of H i gas is more than ∼19 arcmin (20 kpc) larger than that in the Very Large Array map, and the H i gas disc is ∼22 times the optical diameter of NGC 4449. The total H i mass detected for NGC 4449 is 3.07 $\times 10^9\, \rm M_{\odot }$, which is in agreement with that detected by the Effelsberg telescope. We found one H i cloud from the channel map that is in superposition with the optical dwarf galaxy NGC 4449B. This cloud is slightly offset from the NGC 4449B disc, suggesting that it could be gas stripped from NGC 4449B’s optical body when it was disrupted and pulled into the nuclear region of NGC 4449. We also find a region in the outer part of the H i envelope with a peculiar velocity field and double-peaked spectral profiles, whose velocity distribution is consistent with the nearby companion dwarf galaxy DDO 125. This implies that NGC 4449 may have stripped gas out of DDO 125. We suggest that the irregularity of NGC 4449’s huge H i gas halo might originate from interactions with NGC 4449B and DDO 125.
Magnetically threaded thin discs in the presence of the quadrupole magnetic field
Authors: Çıkıntoğlu Sercan 
Published: July 2023

ABSTRACT
Neutron stars might have multipole magnetic fields as implied by recent observations of pulsars. The presence of the quadrupole field might have an effect on the interaction between the disc and the neutron star depending on the location of the inner radius of the disc, and the strength of the quadrupole field. For a quadrudipole stellar field, we calculate the toroidal field generated within the disc, the magnetospheric radius, and the torque exerted on to the star. Also, we deduce the effect of the rotation of the star on the magnetospheric radius which is relevant even for pure dipole magnetic fields.
New estimation of the nuclear de-excitation line emission from the supernova remnant Cassiopeia A
Authors: Liu Bing , Yang Rui-zhi , He Xin-yu , Aharonian Felix 
Published: July 2023

ABSTRACT
MeV nuclear de-excitation lines serve as a unique tool to study low-energy cosmic rays (CRs), containing both spectral and elemental information of the interacting material. In this paper, we estimated the possible nuclear de-excitation lines from the young supernova remnant Cassiopeia A. Given different CR spectral shapes and interacting materials, we found the predicted fluxes of strong narrow line emissions from the remnant are highly model-dependent, ranging from about $1\times 10^{-10}\, {\rm \, cm^{-2}\, s^{-1}}$ to $1\times 10^{-6}\, {\rm \, cm^{-2}\, s^{-1}}$ for the 4.44 MeV narrow line and from about $4\times 10^{-11}\, {\rm \, cm^{-2}\, s^{-1}}$ to $2\times 10^{-7}{\rm \, cm^{-2}\, s^{-1}}$ for the 6.13 MeV narrow line, respectively. Based on the new estimation, we also discussed the detection probability of these line emissions against the MeV diffuse Galactic background under different assumptions of instrument response functions.
Type Ia supernova constraints on compact object dark matter
Authors: Dhawan S , Mörstell E 
Published: July 2023

ABSTRACT
The nature of dark matter (DM) is a central question in cosmology today. While elementary particles could explain DM, compact astrophysical objects such as black holes formed in the early Universe offer a theoretically appealing alternate route. Here, we constrain the fraction of DM that can be made up of primordial black holes (PBHs) with masses $M \gtrsim 0.01\, {\rm M}_\odot$, with Type Ia supernovae. Utilizing the Dyer–Roeder distance relation, we find a maximum fractional amount of DM in compact objects (fp) of 0.50 at 95 per cent confidence level (C.L.), in the flat Lambda cold dark matter model and 0.49 when marginalizing over a constant dark energy equation of state or spatial curvature, demonstrating robustness to the cosmological model. With a prior on the homogeneity parameter, η, including values &gt;1, we derive η = 1.08 ± 0.17, hence, fp &lt; 0.32 at 95 per cent C.L., showing that the prior assumption of η ≤ 1 gives a conservative upper limit on fp. The Hubble constant we infer is consistent with the homogeneous case, showing that inhomogeneities like compact DM cannot account for the observed Hubble tension. In conclusion, we can exclude stellar masses PBHs as comprising all of the observed DM.
