Zusammenfassung: Infektionen sind zwar nicht im Revised Geneva- oder Wells-Score vertreten, doch sie erhöhen das Risiko für eine venöse Thromboembolie (VTE) ähnlich wie bekannte Risikofaktoren (Immobilisation, grössere Operationen, aktive Neoplasien). Dieses erhöhte VTE-Risiko kann nach Infektion sechs bis zwölf Monate persistieren, zudem gilt: Je schwerer die Infektion, desto höher scheint das VTE-Risiko. Infektionen können neben VTEs auch arterielle Thromboembolien begünstigen. So sind 20% der Pneumonien von einem akuten kardiovaskulären Ereignis begleitet (akutes Koronarsyndrom, Herzinsuffizienz, Vorhofflimmern). Auch bei Infekt-assoziiertem Vorhofflimmern orientiert man sich für die Indikation der Antikoagulation am besten am CHA2DS2-VASc-Score.

Zusammenfassung: Die tiefe Hirnstimulation («THS») ist ein minimalinvasives, neurochirurgisches und hypothesengeleitetes Therapieverfahren zur dauerhaften, lokalen Regulation pathologischer Regelkreise. Während die Depression ein heterogenes Syndrom mit multifaktorieller Ätiopathogenese darstellt, fördert die neurowissenschaftliche Forschung die Evidenz zur Identifikation von Mechanismen auf Netzwerkebene, die in der Pathophysiologie der Depression eine tragende Rolle spielen. Der folgende Beitrag gibt einen Überblick über den Stellenwert der THS bei der therapieresistenten oder schwer behandelbaren Depression. Dabei möchten wir praxisnah den Bekanntheitsgrad der THS fördern und die Herausforderungen bei Therapie und Implementierung diskutieren.
A Social Cure in Times of Pandemic Distancing
Authors: Uhlmann Lena Marie , Wegge Jürgen
Published: June 2023

Abstract: Background: Being a member of multiple social groups (multiple group membership, MGM) has beneficial effects on several health outcomes as stated by the social identity theory. MGM can also buffer the negative influences of life-altering events on well-being. The COVID-19 pandemic can be characterized as such an event. Aims: The present study investigated whether MGM is associated with better well-being for older people during the pandemic and if it has a buffer effect on the relationship between pandemic-induced fear and well-being. Method: A cross-sectional survey was conducted with a representative sample ( N = 2,062) of citizens of Dresden, Germany aged 60 or older during the COVID-19 pandemic. MGM was operationalized in two different ways: as a self-assessment of the number of different social groups participants considered themselves a member of and as the number of formal groups people participated in, such as sports groups, clubs, or religious groups. Results: It was found, as expected, for both indicators that people who were members of multiple social groups reported better well-being than people with just one group membership. Participants with no group memberships had the lowest psychological well-being. MGM did, however, not buffer the negative impact of the pandemic-induced fear on well-being. Limitations: Limitations are based on our measurement methods (cross-sectional design and self-reported data). Conclusion: MGM is an important resource for older people even during a pandemic. Potential limitations of the social cure imposed by social distancing rules are discussed and related suggestions for practice are presented.
Quantifying the Value of Learning for Flexible Water Infrastructure Planning

Published: June 2023

Uncertainty in future climate change challenges water infrastructure development decisions. Flexible infrastructure development, in which infrastructure is proactively designed to be changed in the future, can reduce the risk of overbuilding unnecessary infrastructure while maintaining reliable water supply. Flexible strategies assume that water planners will learn over time, updating future climate projections and using that new information to change plans. Previous work has developed methods to incorporate learning using climate observations into flexible planning but has not quantified the impact of different amounts of learning on the effectiveness of flexible planning. In this work, we develop a framework to assess how differences in the amount of learning about climate uncertainty affect the value of flexible water infrastructure planning. In the first part of our framework, we design climate scenarios with different amounts of learning using an exploratory Bayesian modeling approach. Then, we quantify the impacts of learning on flexibility using simulated costs and infrastructure decisions. We demonstrate this framework on a stylized case study of the Mwache Dam near Mombasa, Kenya. Flexible planning is more effective in avoiding over‐ or underbuilding under high‐learning scenarios, especially in avoiding overbuilding in wet climates. This framework provides insight on the climate conditions and learning scenarios that make flexible infrastructure most valuable.
Auroral Oval Morphology: Dawn‐Dusk Asymmetry Partially Induced by Earth's Rotation
Authors: Decotte Margot , Laundal Karl M. , Hatch Spencer M. , Reistad Jone P.
Published: June 2023

The auroral oval morphology has been investigated in previous studies presenting maps of average auroral precipitation. However, such distributions tend to emphasize auroral intensity rather than the actual extent of the auroral oval. We develop a statistical method to characterize the auroral oval morphology by using 20 years of electron energy flux measurements from the Defense Meteorological Satellite Program/Special Sensor J (DMSP/SSJ); instead of relying on auroral oval boundaries, we derive the probability of observing aurora from a threshold of 2.109 eV/cm2/s/sr above which the total energy flux of electrons (in the energy range 1–30 keV) is defined as aurora. We then investigate the auroral occurrence probability (AOP) in the magnetic latitude‐magnetic local time (MLat‐MLT) sectors covered by DMSP for various conditions related to geomagnetic activity. Regardless of those conditions, the AOP distributions reveal a width asymmetry with a wider dawn‐to‐noon sector (06–12 MLT) compared to the dusk‐to‐midnight sector (18–24 MLT), the dawn preference getting even more pronounced as the geomagnetic activity decreases. In the context of an open magnetosphere, we investigate the relation between the observed extent asymmetry in the auroral oval and the magnetospheric plasma convection. Representing the plasma sheet magnetic flux as a one‐dimensional fluid subject to production on the nightside (closing of flux via reconnection) and loss on the dayside (opening of flux), we highlight similarities with the AOP in terms of MLT asymmetries. Finally, making use of this fluid model, we demonstrate that the corotation influence on the plasma convection pattern is consistent with the dawn‐dusk asymmetry observed in the AOP distributions.
Nonlinear restructuring of patterned thin films by residual stress engineering into out-of-plane wavy-shaped electrostatic microactuators for high-performance radio-frequency switches

Published: June 2023

Electrostatic microelectromechanical (MEMS) switches are the basic building blocks for various radio-frequency (RF) transceivers. However, conventional cantilever-based designs of MEMS switches require a large actuation voltage, exhibit limited RF performance, and suffer from many performance tradeoffs due to their flat geometries restricted in two dimensions (2D). Here, by leveraging the residual stress in thin films, we report a novel development of three-dimensional (3D) wavy microstructures, which offer the potential to serve as high-performance RF switches. Relying on standard IC-compatible metallic materials, we devise a simple fabrication process to repeatedly manufacture out-of-plane wavy beams with controllable bending profiles and yields reaching 100%. We then demonstrate the utility of such metallic wavy beams as RF switches achieving both extremely low actuation voltage and improved RF performance owing to their unique geometry, which is tunable in three dimensions and exceeds the capabilities of current state-of-the-art flat-cantilever switches with 2D-restricted topology. As such, the wavy cantilever switch presented in this work actuates at voltages as low as 24 V while simultaneously exhibiting RF isolation and insertion loss of 20 dB and 0.75 dB, respectively, for frequencies up to 40 GHz. Wavy switch designs with 3D geometries break through the design limits set by traditional flat cantilevers and provide an additional degree of freedom or control knob in the switch design process, which could enable further optimization of switching networks used in current 5G and upcoming 6G communication scenarios.

Published: June 2023

Multi-omics analysis is a powerful tool for the detection and study of inter-kingdom interactions, such as those between bacterial and archaeal members of complex biogas-producing microbial communities. In the present study, the microbiomes of three industrial-scale biogas digesters, each fed with different substrates, were analysed using a machine-learning guided genome-centric metagenomics framework complemented with metatranscriptome data. This data permitted us to elucidate the relationship between abundant core methanogenic communities and their syntrophic bacterial partners. In total, we detected 297 high-quality, non-redundant metagenome-assembled genomes (nrMAGs). Moreover, the assembled 16 S rRNA gene profiles of these nrMAGs showed that the phylum Firmicutes possessed the highest copy number, while the representatives of the archaeal domain had the lowest. Further investigation of the three anaerobic microbial communities showed characteristic alterations over time but remained specific to each industrial-scale biogas plant. The relative abundance of various microorganisms as revealed by metagenome data was independent from corresponding metatranscriptome activity data. Archaea showed considerably higher activity than was expected from their abundance. We detected 51 nrMAGs that were present in all three biogas plant microbiomes with different abundances. The core microbiome correlated with the main chemical fermentation parameters, and no individual parameter emerged as a predominant shaper of community composition. Various interspecies H2/electron transfer mechanisms were assigned to hydrogenotrophic methanogens in the biogas plants that ran on agricultural biomass and wastewater. Analysis of metatranscriptome data revealed that methanogenesis pathways were the most active of all main metabolic pathways.
Bacteria-phage coevolution with a seed bank

Published: June 2023

Dormancy is an adaptation to living in fluctuating environments. It allows individuals to enter a reversible state of reduced metabolic activity when challenged by unfavorable conditions. Dormancy can also influence species interactions by providing organisms with a refuge from predators and parasites. Here we test the hypothesis that, by generating a seed bank of protected individuals, dormancy can modify the patterns and processes of antagonistic coevolution. We conducted a factorially designed experiment where we passaged a bacterial host (Bacillus subtilis) and its phage (SPO1) in the presence versus absence of a seed bank consisting of dormant endospores. Owing in part to the inability of phages to attach to spores, seed banks stabilized population dynamics and resulted in minimum host densities that were 30-fold higher compared to bacteria that were unable to engage in dormancy. By supplying a refuge to phage-sensitive strains, we show that seed banks retained phenotypic diversity that was otherwise lost to selection. Dormancy also stored genetic diversity. After characterizing allelic variation with pooled population sequencing, we found that seed banks retained twice as many host genes with mutations, whether phages were present or not. Based on mutational trajectories over the course of the experiment, we demonstrate that seed banks can dampen bacteria-phage coevolution. Not only does dormancy create structure and memory that buffers populations against environmental fluctuations, it also modifies species interactions in ways that can feed back onto the eco-evolutionary dynamics of microbial communities.

Kidney cancer is a common urologic malignancy with either laparoscopic (LPN) or robotic partial nephrectomy as therapeutic options of choice for localized tumors. However, renal resection and suturing are challenging steps of the procedure that can lead to complications such as prolonged warm ischemia, bleeding, and urinary fistulas. LPN with a diode laser is an efficient technique due to its cutting and/or coagulation attributes. Surprisingly, key laser features such as wavelength and power remain undefined. Using a large porcine model, we evaluated the laser range of wavelength and power in a clamp-free LPN and compared it to the established gold-standard LPN technique (i.e., cold-cutting and suturing). By analyzing surgery duration, bleeding, presence of urine leak, tissue damage related to the resected renal fragment and the remaining organ, hemoglobin levels, and renal function, we show that an optimized experimental diode laser clamp-free LPN (wavelength, 980 nm; power, 15 W) had shorter surgery time with less bleeding, and better postoperative renal function recovery when compared to the well-established technique. Together, our data indicate that partial nephrectomy with a diode laser clamp-free LPN technique is an improved alternative to the gold-standard technique. Therefore, translational clinical trials towards human patient applications are readily feasible.
GTMNet: a vision transformer with guided transmission map for single remote sensing image dehazing
Authors: Li Haiqin , Zhang Yaping , Liu Jiatao , Ma Yuanjie
Published: June 2023

Existing dehazing algorithms are not effective for remote sensing images (RSIs) with dense haze, and dehazed results are prone to over-enhancement, color distortion, and artifacts. To tackle these problems, we propose a model GTMNet based on convolutional neural networks (CNNs) and vision transformers (ViTs), combined with dark channel prior (DCP) to achieve good performance. Specifically, a spatial feature transform (SFT) layer is first used to smoothly introduce the guided transmission map (GTM) into the model, improving the ability of the network to estimate haze thickness. A strengthen-operate-subtract (SOS) boosted module is then added to refine the local features of the restored image. The framework of GTMNet is determined by adjusting the input of the SOS boosted module and the position of the SFT layer. On SateHaze1k dataset, we compare GTMNet with several classical dehazing algorithms. The results show that on sub-datasets of Moderate Fog and Thick Fog, the PSNR and SSIM of GTMNet-B are comparable to that of the state-of-the-art model Dehazeformer-L, with only 0.1 times of parameter quantity. In addition, our method is intuitively effective in improving the clarity and the details of dehazed images, which proves the usefulness and significance of using the prior GTM and the SOS boosted module in a single RSI dehazing.

Published: June 2023

Docetaxel-induced fluid retention (DIFR) cumulatively occurs and is one of the most troublesome adverse effects. This study aimed to determine whether high dose dexamethasone (DEX) could prevent DIFR during breast cancer treatment. Breast cancer patients receiving docetaxel (75 mg/m2)-containing regimens were divided into 4 and 8 mg/day DEX groups, with each DEX dose administered on days 2–4 and retrospectively assessed. Incidence of greater than or equal to grade 2 DIFR was significantly lower in the 8 mg group (13.0%) compared to the 4 mg group (39.6%, P = 0.001). All-grade DIFR was also less in the 8 mg group (P = 0.01). Furthermore, the maximum variation of body weight was significantly lower in the 8 mg group (P = 0.0003). These results were also confirmed in the propensity score-matched population. Additionally, time-related DIFR incidence was also significantly delayed in the 8 mg group (P = 0.0005). Our study revealed that high dose DEX prevents DIFR. Therefore, further studies on its management are required for less onerous chemotherapy provision with better DIFR control.
Nanophotonic resonator assisted photonic spin Hall enhancement for sensing application
Authors: Goyal Amit Kumar , Divyanshu Divyanshu , Massoud Yehia
Published: June 2023

This manuscript presents a dielectric resonator structure with altered dispersion characteristics to enhance the photonic spin Hall effect (PSHE). The structural parameters are optimized to enhance the PSHE at 632.8 nm operating wavelength. The thickness-dependent angular dispersion analysis is carried out to optimize the structure and obtain the exceptional points. The PSHE-induced spin splitting shows a high sensitivity to the optical thickness of the defect layer. This gives a maximum PSHE-based transverse displacement (PSHE-TD) of around 56.66 times the operating wavelength at an incidence angle of 61.68°. Moreover, the structure’s capability as a PSHE-based refractive index sensor is also evaluated. The analytical results demonstrate an average sensitivity of around 33,720 μm/RIU. The structure exhibits around five times higher PSHE-TD and approximately 150% improvement in sensitivity than the recently reported values in lossy mode resonance structures. Due to the purely dielectric material-assisted PhC resonator configurations and significantly higher PSHE-TD, the development of low-cost PSHE-based devices for commercial applications is envisaged.

Published: June 2023

HMG protein Tox4 is a regulator of PP1 phosphatases with unknown function in development. Here we show that Tox4 conditional knockout in mice reduces thymic cellularity, partially blocks T cell development, and decreases ratio of CD8 to CD4 through decreasing proliferation and increasing apoptosis of CD8 cells. In addition, single-cell RNA-seq discovered that Tox4 loss also impairs proliferation of the fast-proliferating double positive (DP) blast population within DP cells in part due to downregulation of genes critical for proliferation, notably Cdk1. Moreover, genes with high and low expression level are more dependent on Tox4 than genes with medium expression level. Mechanistically, Tox4 may facilitate transcriptional reinitiation and restrict elongation in a dephosphorylation-dependent manner, a mechanism that is conserved between mouse and human. These results provide insights into the role of TOX4 in development and establish it as an evolutionarily conserved regulator of transcriptional elongation and reinitiation.

Published: June 2023

Flow-induced noise hybrid prediction method based on sound wave boundary condition is an effective numerical method to deal with a flow-induced noise problems of complex configuration. This method can not only finely simulate the sound source, but also analyze the noise propagation characteristics. In this paper, numerical methods such as space-time discrete scheme and boundary conditions involved in discrete solution of acoustic perturbation equations(APE) are developed, and strategies such as adding buffer layer are proposed to improve divergence caused by numerical discontinuity at the junction of sound source region and propagation region, so as to establish a high-precision flow-induced noise hybrid method. In order to study the rationality of flow-induced noise hybrid method, the numerical simulation of acoustic radiation at the trailing edge of NACA0012 airfoil in BANC experiment was carried out. Compared with the results of sound field solved by large eddy simulation method, the analysis shows that the high-precision flow-induced noise hybrid method based on sound wave boundary conditions can predict the spatial sound field distribution with high precision and directly reflect the interaction between sound waves. Compared with the results of large eddy simulation, the error of sound pressure level is less than 2 dB, and the noise directional distribution trend is consistent.

As an important part of the wing, the skin deformation accuracy directly affect the aerodynamic performance of the aircraft in different environments. Based on the idea of easy processing and easy deformation, a method for designing variable section thickness skin for trailing edge of variable camber wings is proposed. In this paper, firstly, the thickness and length of each segment of 3~8 segments of trailing edge skin are optimized. Then the deformation results of different segments of skin are compared and analyzed. Finally, the correctness of the design results and the effectiveness of the method are verified by using stacked skin experiment.

Published: June 2023

Based on the NM propositional logic system of nilpotent minimum logic, the concept of the integral truth degree of the formula is firstly proposed by integrating the function induced by the formula, and the MP rule and HS rule of the integral truth degree are proved by means of the integral invariance. Secondly, in NM propositional logic the integral similarity and integral pseudo-distance are introduced into the set of general formulas of the system, and some good properties about the similarity and pseudo-distance are proved. Finally, in terms of the concept of divergence degrees and diameter, a new membership function for reflecting the consistency degrees of theories in NM propositional fuzzy logic is proposed, which is proved that of inconsistent theories are equal to 0 and that of completely consistent theories are equal to 1.
Abordaje Volar de las Fracturas de Radio Distal y la Vaina del Flexor Carpi Radialis. Una Encuesta Regional y Nacional
Authors: Scott-Tennent De Rivas Ana , Forcada Calvet Pau , Mustafa Gondolbeu Amer , Prats Gispert Laura , Bonjorn Martí Marta
Published: June 2023

Introducción Se han descrito diferentes abordajes volares para para la osteosíntesis de las fracturas de radio distal; algunos de ellos acceden a través de la vaina del flexor carpi radialis (FCR) (Abordaje FCR), mientras que otros evitan abrirla (Abordaje Henry clásico). En la literatura no encontramos estudios que comparen si existen diferencias entre ellos. Nuestra hipótesis es que, a pesar de ello, existen diferentes opiniones al respecto entre los cirujanos que operan estas fracturas.

Materiales y métodos Se realizó una encuesta online a los miembros de la Societat Catalana de Cirurgia Ortopèdica i Traumatologia (SCCOT) y a los de la Sociedad Española de Cirugía de Mano (SECMA) a través de un cuestionario anónimo utilizando la plataforma de SurveyMonkey (Momentive Inc., San Mateo, California, EE. UU.
www.momentive.ai) con el objetivo de valorar sus preferencias con respecto al manejo de la vaina del tendón del FCR. El análisis de las respuestas se realizó a través de tablas con filtros y tabulaciones cruzadas utilizando el software de análisis del mismo programa.

Resultados Desde Octubre 2020-2021 se obtuvieron 99 respuestas, 55 cirujanos de extremidad superior o mano y 41 cirujanos ortopédicos generales. 72,72% abren la vaina del FCR, 63% creen que ello facilita su cirugía. 21,21% prefiere respetar la vaina tendinosa y el 53% opinan que preservarla disminuye el riesgo de complicaciones, siendo el exceso de fibrosis y la lesión yatrogénica de las estructuras neurovasculares las más temidas.

Conclusiones Creemos que existe discrepancia de opiniones en cuanto al manejo de la vaina del tendón del FCR en el abordaje volar de las fracturas de radio distal y la justificación de elegir un abordaje u otro. Dada la alta incidencia de estas fracturas y la ausencia de análisis clínicos previos, los resultados obtenidos en esta encuesta podrían servir como base para la realización de estudios clínicos en el futuro.

Published: June 2023

Introducción La artrodesis de muñeca ha evolucionado con el tiempo con el uso creciente de un implante más rígido y un aumento resultante en las tasas de consolidación. Sin embargo, complicaciones como la irritación de los tendones extensores han llevado al desarrollo e introducción de implantes mejorados de bajo perfil en los últimos años. Este estudio tuvo como objetivo examinar los factores que influyen en la curación de la artrodesis total de la muñeca y la frecuencia de complicaciones utilizando una placa de bajo perfil del mismo fabricante.

Materiales y métodos Se trata de un estudio retrospectivo que analiza las historias clínicas y radiografías de pacientes sometidos a artrodesis de muñeca utilizando una placa de fusión de muñeca Aptus® 2.5 Trilock larga o corta (Medartis AG, Basilea, Suiza) entre 2015 y 2021 en el mismo hospital. Se analizaron variables epidemiológicas y clínicas. La prueba de Chi-cuadrado o Prueba exacta de Fischer se utilizó para comparar las proporciones y los resultados, con un valor p ≤ 0,05 que se considera estadísticamente significativo.

Resultados De las 85 artrodesis de muñeca realizadas, se observó una consolidación del 100% en un promedio de 4,6 meses después de la cirugía. La mayoría de los pacientes eran no fumadores (80%), hombres (69,4%), con una edad media de 50,7 años. La tasa de complicaciones fue del 10,5%, todas las cuales se resolvieron después de una intervención adicional, requiriendo solo una extracción del implante. El tiempo medio de consolidación en los fumadores fue de 5,8 meses y en los no fumadores de 4,2 meses (p = 0,03). El tiempo medio de consolidación después de los procedimientos de placa larga fue sutilmente más corto que con el uso de placa corta, pero no tuvo significación estadística.

Conclusión Las artrodesis de la muñeca en el presente estudio tuvieron una tasa de consolidación del 100% con una baja tasa de complicaciones y sin diferencias en los resultados en cuanto a la colocación del injerto, la fusión de la articulación carpometacarpiana o los perfiles demográficos de los pacientes. Fumar se asoció con un mayor tiempo de consolidación, pero no condujo a la pseudoartrosis.

Published: June 2023

Coherent technology has been employed in long-haul transmission systems in the past decade, with growing demand for capacity at ever-lower costs per bit. High-performance coherent modulators with high data rates, wide bandwidth, small footprint, and low power operation are highly desired. Toward this end, we propose a folded thin-film lithium niobate (TFLN) dual-polarization in-phase quadrature modulator featuring a low half-wave voltage of 1 V and a compact footprint of 4 × 8 mm2. To suppress RF wavefront distortion and optimize high-frequency electro-optic performance, we utilize air-bridge structures in the U-turns of the traveling-wave electrodes. As a demonstration of the long-haul transmission capacities with our device, we present driverless 703 Gb/s/λ line-rate transmissions, with a subcarrier modulation scheme, over a 1120 km single-mode fiber link. Here, for the first time, to our knowledge, our device allows for attojoule-per-bit level electrical energy consumption over transmission distances above 1000 km. The device opens opportunities for much lower-cost and capacity-intensive coherent systems that consume ultra-low power, support high data rate, and work in small spaces.
Evaluation of ACCESS-S1 seasonal forecasts of growing season precipitation for Western Australia’s wheatbelt region
Authors: Firth Rebecca , Kala Jatin , Hudson Debra , Evans Fiona
Published: June 2023

Seasonal forecasts are increasingly important tools in agricultural crop management. Regions with Mediterranean-type climates typically adopt rain-fed agriculture with minimal irrigation, hence accurate seasonal forecasts of rainfall during the growing season are potentially useful in decision making. In this paper we examined the bias and skill of a seasonal forecast system (ACCESS-S1) in simulating growing season precipitation (GSP) for south-west Western Australian (SWWA), a region with a Mediterranean-type climate and significant cereal crop production. Focusing on July–September (3-month) and May–October (6-month) forecasts, with 0- and 1-month lead times, we showed that overall ACCESS-S1 had a dry bias for SWWA rainfall and a tendency to simulate close to average rainfall during both wetter and drier than average rainfall years. ACCESS-S1 showed particularly poor skill at these timeframes for very wet and very dry years. The limitations in ACCESS-S1 for SWWA GSP were associated with inaccuracies in the timing of heavy rainfall events. In addition, limitations of the ACCESS-S1 model in accurately capturing SST and wind anomaly patterns over the tropical Indian Ocean during extreme rainfall years also contributed to errors in SWWA GSP forecasts. Model improvements in these regions have the potential to improve seasonal rainfall forecasts for SWWA.

Main text

A measurement comparison of DC voltage, DC current, DC resistance, AC voltage and AC current has been carried out among seventeen national metrology laboratories with the travelling standards 6½ digit multimeter (Fluke model 8846A) as Loop A, Loop B and Loop C for the nominal values of the measured parameters DC voltage (100 mV, 1 V, 10 V, -10 V, 100 V and 1000 V), DC current (10 mA and 1 A), DC resistance (100 Ω, 1 kΩ and 10 kΩ (using 4-wire), AC voltage (100 mV, 1 V, 10 V, 100 V and 700 V at 40 Hz and 1 kHz) and AC current (10 mA and 1 A at 40 Hz and 1 kHz) for establishing the degrees of equivalence among the participating NMIs.

A novel quantitative inverse scattering scheme using interior resonant modes
Authors: He Youzi , Liu Hongyu , Wang Xianchao
Published: June 2023

This paper is devoted to a novel quantitative imaging scheme of identifying impenetrable obstacles in time-harmonic acoustic scattering from the associated far-field data. The proposed method consists of two phases. In the first phase, we determine the interior eigenvalues of the underlying unknown obstacle from the far-field data via the indicating behavior of the linear sampling method. Then we further determine the associated interior eigenfunctions by solving a constrained optimization problem, again only involving the far-field data. In the second phase, we propose a novel iteration scheme of Newton’s type to identify the boundary surface of the obstacle. By using the interior eigenfunctions determined in the first phase, we can avoid computing any direct scattering problem at each Newton’s iteration. The proposed method is particularly valuable for recovering a sound-hard obstacle, where the Newton’s formula involves the geometric quantities of the unknown boundary surface in a natural way. We provide rigorous theoretical justifications of the proposed method. Numerical experiments in both 2D and 3D are conducted, which confirm the promising features of the proposed imaging scheme. In particular, it can produce quantitative reconstructions of high accuracy in a very efficient manner.

The precise control and manipulation of the qubit state are vital for quantum simulation and quantum computation. In superconducting circuits, one notorious error comes from the crosstalk of microwave signals applied to different qubit control lines. In this work, we present a method for the calibration and cancellation of the microwave crosstalk and experimentally demonstrate its effectiveness in a superconducting 10-qubit chain. The method is convenient and efficient especially for calibrating the microwave crosstalk with large amplitudes and variations, which can be performed successively to reduce the microwave crosstalk by two to three orders. The qubit chain with microwave driving is governed by one-dimensional (1D) Bose–Hubbard model in transverse field, which is nonintegrable and shows thermalization behaviour during the time evolution from certain initial states. Such thermalization process is observed with excellent agreement between experiment and theory further confirming the effective global cancellation of the microwave crosstalk.
Geometric discord of tripartite quantum systems

Published: June 2023

We study the quantification of geometric discord for tripartite quantum systems. Firstly, we obtain the analytic formula of geometric discord for tripartite pure states. It is already known that the geometric discord of pure states reduces to the geometric entanglement in bipartite systems, the results presented here show that this property is no longer true in tripartite systems. Furthermore, we provide an operational meaning for tripartite geometric discord by linking it to quantum state discrimination, that is, we prove that the geometric discord of tripartite states is equal to the minimum error probability to discriminate a set of quantum states with von Neumann measurement. Lastly, we calculate the geometric discord of three-qubit Bell diagonal states and then investigate the dynamic behavior of tripartite geometric discord under local decoherence. It is interesting that the frozen phenomenon exists for geometric discord in this scenario.
A Text-Detecting Method Based on Improved CTPN
Authors: Zhang Shaowei , Duan Anming , Sun Yongjiao
Published: June 2023

In the intelligent electric power inspection system, when the nameplate image is collected on site and transmitted back to the server, the server system needs to identify the text information in the nameplate, and the detection of the text area is a key step. By discussing the CTPN algorithm, this paper proposes an improved CTPN text detection algorithm, which makes up for its shortcomings in identifying oblique text and further improves the detection precision.
A Novel Encoder-Decoder Structure-based Transformer for Fine-Resolution Remote Sensing Images
Authors: Wang Guixian , Huang Dandan , Geng ZhenYe , Liu Zhi , Duan Jin
Published: June 2023

Full convolution neural network (FCN) based on an encoder-decoder structure has become a standard network in the semantic segmentation domain. Encoder-decoder architecture is an effective means to get finer-grained performance. Encoders constantly extract multilevel features, and then use decoders to gradually introduce low-level features into high-level features. Context information is critical for accurate segmentation, which is the main direction of semantic segmentation at present. So many efforts have been made to make better use of this kind of information, including codec structure, void convolution (expanded convolution), and attention mechanism. However, most of these schemes are based on Resnet or other variants of convolution network FCN, which makes it unable to get rid of the defective local receptive field of convolution itself. In this work, we introduce the pyramid visual converter (PVT) to replace the traditional full convolution network architecture, and design a novel encoder-decoder architecture to more effectively utilize the context information.
Geometric uncertainty relations on Wigner–Yanase skew information
Authors: Chen Bin , Lian Pan
Published: June 2023

We formulate uncertainty relations based on Wigner–Yanase skew information. By using the Kirillov–Kostant–Souriau Kähler structure on the quantum phase space, we present a new geometric uncertainty relation associated to the skew information, which is shown to be tighter than the existing ones. Furthermore, we provide a skew information-based product uncertainty relation, in which the lower bound can also be used to capture the non-commutativity of the observables. We also attempt to generalize the geometric uncertainty inequalities to the case of arbitrary three observables, where the Kähler structure plays a vital role in the proof.

When a Series’ Main Protagonist Gets Stolen and Sold – A Study of NFTs and Their Approaches to Copyright Licensing
Authors: Bischoff Susan
Published: June 2023

Over the past two years non-fungible tokens (NFTs) have become a highly popular, though extremely volatile trade asset. As mere data sets on the blockchain, NFTs are challenging the law to define the legal positions they entail. This article examines NFTs from the angle of copyright licensing, looking at it from a European perspective with the main focus on German law. Based on the technical specifics of NFTs, the paper evaluates the relevant legal position required for a permitted use of tokenized copyrighted content and how such a position may be obtained in the context of NFT trading. A review of the copyright schemes of 21 of the most sought-after NFT collections sets out the current state of licensing and identifies the prevailing legal uncertainties. The fact that these are not merely theoretical is then shown by the turbulent case of a ‘stolen’ ape avatar, tokenized by an NFT, that was set to star in a live-action animated series.
The genome of okra (Abelmoschus esculentus) provides insights into its genome evolution and high nutrient content

Published: June 2023

Okra (Abelmoschus esculentus) is an important vegetable crop with high nutritional value. However, the mechanism underlying its high nutrient content remains poorly understood. Here, we present a chromosome-scale genome of okra with a size of 1.19 Gb. Comparative genomics analysis revealed the phylogenetic status of A. esculentus, as well as whole-genome duplication (WGD) events that have occurred widely across the Malvaceae species. We found that okra has experienced three additional WGDs compared with the diploid cotton Gossypium raimondii, resulting in a large chromosome number (2n = 130). After three WGDs, okra has undergone extensive genomic deletions and retained substantial numbers of genes related to secondary metabolite biosynthesis and environmental adaptation, resulting in significant differences between okra and G. raimondii in the gene families related to cellulose synthesis. Combining transcriptomic and metabolomic analysis, we revealed the relationship between gene expression and metabolite content change across different okra developmental stages. Furthermore, the sinapic acid/S-lignin biosynthesis-related gene families have experienced remarkable expansion in okra, and the expression of key enzymes involved in the sinapic acid/S-lignin biosynthesis pathway vary greatly across developmental periods, which partially explains the differences in metabolite content across the different stages. Our study gains insights into the comprehensive evolutionary history of Malvaceae species and the genetic basis that underlies the nutrient content changes in okra, which will facilitate the functional study and genetic improvement of okra varieties.
Coherence Improvement of Dual-Lens Electron Holography
Authors: Wang Yun-Yu , Wang Zhouguang , Jin Qiang
Published: June 2023

Coherence is one of the limiting factors in off-axis electron holography applications. This paper reports methods to improve coherence ∼18-fold by using a smaller biprism and implementing a direct electron counting camera (K-camera) in combination with an imaging filter system. We achieved 0.4 nm fringe spacing with a 1.5 μm field-of-view and ∼33% fringe contrast. The maximum coherence number, N′, of ∼1.8 × 103 was achieved, where N′ is defined as the number of fringes times fringe contrast. High spatial resolution junction profile images (nm scale) of n-channel and p-channel field-effect transistors (nFET and pFET) are demonstrated with a large field-of-view (μm scale).
