Published: October 2023

AbstractEarly screening for gastrointestinal diseases is of vital importance for reducing mortality through introducing early intervention. In this paper, a biomimetic artificial whisker-based hardware system with artificial intelligence-enabled self-learning capability is proposed for endoluminal diagnosis. The proposed method provides an end-to-end screening strategy based on tactile information to extract the structural and textural details of the tissues in the lumen, enabling objective screening and reducing the inter-endoscopist variability. Benchmark performance analysis of the proposed was conducted to assess the electrical characteristics and core functions. To validate the feasibility of the proposed for endoluminal diagnosis, an ex-vivo study was conducted to detect some common tissue structures and our method shows promising results with the test accuracy up to 94.44% with 0.9167 kappa. This previously unexplored tactile-based method could potentially enhance or complement the current endoluminal diagnosis.

Published: October 2023

AbstractThe development and use of architectured structures is changing the means by which we design and fabricate soft robots. These materials utilize their topology and geometry to control physical and mechanical structural properties. We propose an architectured structure based on trimmed helicoids that allows for independent regulation of the bending and axial stiffness which facilitates tuneability of the resulting soft robot properties. Leveraging FEA and computational analysis we select a geometry that provides an optimal trade-off between controllability, sensitivity to errors in control, and compliance. By combining these modular trimmed helicoid structures in conjunction with control methods, we demonstrate a meter-scale soft manipulator that shows control precision, large workspace, and compliant interactions with the environment. These properties enable the robot to perform complex tasks that leverage robot-human and robot-environment interactions such as human feeding and collaborative object manipulation.

Abstract
Objectives: Alanine aminotransferase (ALT) expression is highly elevated in the serum of patients with hepatocellular carcinoma. However, the role of ALT isoenzymes in the total ALT activity remains unclear. In the present study, we systematically investigated the role of ALT isoenzymes in alcoholic and non-alcoholic fatty liver cancer. Materials and methods: The expression of ALT1 and ALT2 at the mRNA and protein levels in 25 paired primary liver cancer tissues was detected by reverse transcription quantitative PCR (RT-qPCR), Western blotting, and immunohistochemistry. Serum ALT activity was determined using an automated biochemical analyzer. Results: The mRNA and protein expression levels of ALT1 and ALT2 were lower in the tissues of alcoholic and non-alcoholic fatty liver cancers than in the paracancerous tissues. Notably, ALT2 was highly expressed in non-alcoholic fatty liver cancer tissues compared with alcoholic fatty liver cancer tissues. Total serum ALT activity was mainly contributed by ALT1 in alcoholic fatty liver cancer, whereas ALT1 contributed only marginally more to the total ALT activity than ALT2 in non-alcoholic fatty liver cancer. ALT2/ALT1 ratio can well discriminate normal control group, alcoholic liver cancer and non-alcoholic liver cancer. Conclusion: ALT1 contributed more to the total ALT activity than ALT2 in both alcoholic and non-alcoholic fatty liver cancer. Serum ALT2 to ALT activity was higher in non-alcoholic fatty liver cancer than that in alcoholic fatty liver cancer. ALT2/ALT1 ratio has some diagnostic significance for alcoholic and non-alcoholic liver cancer.

Abstract
The need to minimise the impact of phytosanitary treatments for disease control boosted researchers to implement techniques with less environmental impact. The development of technologies using molecular mechanisms based on the modulation of metabolism by short dsRNA sequences appears promising. The intrinsic fragility of polynucleotides and the high cost of these techniques can be circumvented by nanocarriers that protect the bioactive molecule enabling high efficiency delivery to the leaf surface and extending its half-life.
In this work, a specific protocol was developed aiming to assess the best methodological conditions for the synthesis of low-size chitosan nanoparticles (NPs) to be loaded with nucleotides. In particular, NPs have been functionalised with partially purified Green Fluorescent Protein dsRNAs (GFP dsRNA) and their size, surface charge and nucleotide retention capacity were analysed. Final NPs were also stained with FITC and sprayed on Nicotiana benthamiana leaves to assess, by confocal microscopy, both a distribution protocol and the fate of NPs up to 6 days after application.
Finally, to confirm the ability of NPs to increase the efficacy of dsRNA interference, specific tests were performed: by means of GFP dsRNA-functionalised NPs, the nucleotide permanence during time was assessed both in vitro on detached wild-type N. benthamiana leaves and in planta; lastly, the inhibition of Botrytis cinerea on single leaves was also evaluated, using a specific fungal sequence (Bc dsRNA) as the NPs’ functionalising agent.
The encouraging results obtained are promising in the perspective of long-lasting application of innovative treatments based on gene silencing.
AC losses calculation of parallel multi‐strand flat wire windings for automotive drive motor
Authors: Yang Peipei , Liang Yanping , Liu Jia , Zhang Ke 
Published: October 2023

AbstractAutomobile drive motor with flat wire winding has improved the slot fill factor and efficiency. However, under the current environment of drive motors development to high frequency and voltage, the increase in winding AC loss has weakened those advantages. Accurate analysis of AC loss and the design of high‐performance windings have become the key issues and difficulties in the design process of drive motors. Based on the winding AC loss generation mechanism, the authors propose a winding AC loss analysis method, which can effectively separate DC loss, eddy current loss, and circulating current loss. The method is used to analyse winding AC loss of 60 kW flat wire winding permanent magnet synchronous motor (PMSM). In addition, parallel multi‐strand flat wire windings are proposed to reduce the winding AC loss and eliminate the limitation of the magnetic load of the motor on the selection of winding layers. The AC loss of the parallel multi‐strand flat wire windings at different frequencies is calculated, which demonstrates the effectiveness of the proposed winding topology in reducing the winding AC loss. In addition, the correctness of the simulation model was verified through experiments, and the loss calculation method was verified through finite element analysis.
Enhanced flexibility utilization and coordinated dispatch method of energy‐intensive enterprises in power systems under time of use prices

Published: October 2023

AbstractPower system can utilize the flexibility provided by energy‐intensive enterprises (EIEs) for large‐scale renewable energy penetration. However, system operators cannot obtain the manufacture scheme of EIEs due to business privacy protection. Furthermore, highly regulated electricity prices further restrict the flexible utilization of EIEs. To overcome these issues, a coordinated dispatch framework between power system and EIEs under the intrinsic time of use (TOU) prices is designed in this paper, which requires only several boundary information for interaction. Firstly, the mathematical formulation of EIEs is given based on the inherent features analysis of typical production equipment and the optimal operation scheme of EIEs can be obtained. Then, considering uncertainties of both source and loads, the purchasing energy of EIEs from the network can be adjusted through the designed framework to track renewable energy dynamics and the clear equivalence class method is used to solve fuzzy chance constrained programming. Next, the improved Asymmetric Nash Bargaining (ANB) method is adopted to carry out the distribution of benefits. Finally, a modified IEEE‐30 test system is given to verify the feasibility of the proposed method, which can effectively improve the regional consumption level of renewable energy and ensure interests of all sides.
Secondary control with reduced communication requirements for accurate reactive power sharing in AC microgrids
Authors: Baharizadeh Mehdi , Golsorkhi Mohammad Sadegh , Savaghebi Mehdi 
Published: October 2023

AbstractA secondary control method is proposed for accurate reactive power sharing as well as frequency and voltage restoration in islanded AC microgrids (MGs). The proposed method consists of an MG secondary controller, local secondary controllers for distributed energy resources (DERs), and a low‐bandwidth communication link for broadcasting common data from the MG secondary controller to DERs. The broadcasted data includes the MG point of common coupling voltage magnitude and a common vertical shift for frequency and voltage restoration. Local secondary controllers calculate specific shifts for the Q‐V droop characteristic of each dispatchable DER and the V‐Q reverse droop characteristic of each photovoltaic (PV) system, aligning their operating points with the Q‐VPCC and VPCC‐Q droop characteristics, respectively. By employing VPCC as a common global variable, coordination of reactive power generation of all dispatchable DERs and PV systems is achieved, enabling accurate reactive power sharing. Importantly, in the proposed scheme, the required communication bandwidth and the communication burden are minor and are not increased with the number of DERs. Additionally, the DERs are relieved of the need for data transmission capability. The small signal stability of the proposed method is examined and its effectiveness is validated through Hardware‐in‐the‐Loop (HIL) experimental results.
Tracheobronchiale Verletzungen
Authors: Herrmann Dominik , Hecker Erich 
Published: October 2023

ZusammenfassungTracheobronchiale Verletzungen sind selten, gehen aber mit einer hohen Morbidität und Letalität einher. Dies liegt vor allem in Nebenerkrankungen und Begleitverletzungen der Patienten begründet. Eine grundsätzliche Klassifikation differenziert tracheobronchiale Verletzungen nach iatrogener Ursache sowie stumpfen wie auch penetrierenden Traumata.Die genaue Inzidenz der Verletzungen ist unklar, da viele iatrogene Verletzungen inapparent verlaufen und ein Großteil der Patienten nach einer traumatischen Verletzung vor einer Behandlung im Krankenhaus verstirbt.Patienten mit Verdacht auf eine tracheobronchiale Verletzung verlangen daher nach besonderer Aufmerksamkeit, einer schnellen Diagnostik und zügigem therapeutischem Vorgehen.Die häufigsten Symptome sind Dyspnoe, Hämoptysen, Hautemphysem und Stridor. Die Bronchoskopie stellt die wichtigste diagnostische Maßnahme zur Beurteilung des Ausmaßes der Verletzung dar.In Abhängigkeit der diagnostischen Befunde und dem klinischen Erscheinungsbild der Patienten gibt es verschiedene therapeutische Optionen, wobei das konservative Management an Bedeutung gewinnt. Gerade bei schwerstkranken Patienten kann im Rahmen eines risikostratifizierten Vorgehens neben einem operativen Eingriff oder einer bronchoskopischen Stentimplantation auch ein rein konservatives Vorgehen gewählt werden. Zur Planung des therapeutischen Managements ist bei jedem Patienten die jeweilige Symptomatik wegweisend.

What is newsworthy about Covid-19? A corpus linguistic analysis of news values in reports by China Daily and The New York Times
Authors: Liu Siyang , Yu Hailing 
Published: October 2023

AbstractIntegrating corpus linguistic analysis with news values, this article investigates how the Covid-19 pandemic in different countries is represented as newsworthy byChina Daily(CD) andThe New York Times(NYT), two news outlets with different cultural and political backgrounds. A distinction is made between reports on the pandemic in the newspaper’s home country and reports on the pandemic in other countries. Three corpus linguistic techniques, i.e., keywords list, collocation, and concordance, are used to analyze the headlines and leads of 2572 news reports published in 2020 and 2021. Analysis results show that when presenting the pandemic in domestic news, CD tends to highlight Proximity, Positivity, and Personalization, whereas NYT gives more prominence to Eliteness and Personalization. When the pandemic in other countries is presented, CD foregrounds Negativity, Impact, Superlativeness, and Eliteness, whereas NYT focuses on Negativity, Impact, and Proximity. Compared with NYT, CD shows a stronger tendency to adopt positive self-representation and negative other-representation in its coverage of the Covid-19 pandemic. Apart from the analysis results, the significance of the study also lies in its demonstration of the applicability of a corpus linguistic approach to news values analysis.

Context Several assisted reproduction techniques have been proposed for collared peccaries due to the interest in its conservation. However, there is little information about the requirements for sperm capacitation, an initial step in in vitro fertilisation. Aims We aimed to determine the optimal conditions for collared peccary sperm capacitation by comparing Tyrode’s albumin lactate pyruvate (TALP) or the same media plus heparin, caffeine, or their combination at different exposure times (1, 3, and 6 h). Methods The samples were evaluated for kinetic parameters, membrane functionality and integrity, mitochondrial activity, morphology, DNA integrity, reactive oxygen species (ROS) expression levels, capacitation, and sperm binding ability using swine oocytes. Key results Samples incubated with caffeine or heparin had a higher percentage of capacitated spermatozoa. The maximum percentage of capacitation was achieved after 3 h of incubation with either agent. Moreover, spermatozoa subjected to heparin capacitation showed better motility than when subjected to caffeine, and lower ROS expression levels after 1 h. No differences were observed among incubation times for the binding ability. Conclusions In summary, collared peccary spermatozoa can be capacitated with caffeine or heparin; however, heparin better maintains sperm motility and ROS expression levels. The co-incubation of gametes in a medium with heparin for 3 h could be efficient for in vitro fertilisation in collared peccaries. Implications This result will contribute to the development of assisted reproduction techniques for conservation and productivity of collared peccaries.
Corpus-driven conceptual analysis of epidemic and coronavirus for the Humanitarian Encyclopedia
Authors: Chambó Santiago , León Araúz Pilar 
Published: October 2023

Abstract
Terminological conceptual analysis can be applied to purposes beyond terminology work. This article presents a Frame-based Terminology approach adapted to analyse concepts and inform the content of entries in the Humanitarian Encyclopedia. It proposes a method for conceptual analysis by systematising the extraction of knowledge rich contexts (KRCs) around corpus querying tasks through semantic sketch grammars (SSGs) and macros with knowledge patterns (KPs). KRCs are curated manually, modelled into conceptual propositions, and combined with corpus metadata into unified datasets. The method was tested on epidemic and coronavirus and their results are presented. This study provides a preliminary model to operationalise the study of conceptual variation. It also identifies the areas of terminological conceptual analysis with the potential to be informed by other research methods towards creating a standalone methodology.

Abstract
A nonlocal modified NLS (mNLS) equation is studied by using Dbar method and nonlocal reduction. The nonlocal coupled modified NLS (cmNLS) equation and its Lax representation are derived by introducing bi-Dbar problem and parity condition. The special spectral transform matrices are defined to get the solutions of nonlocal cmNLS equation. The general reduction conditions from the nonlocal cmNLS equation to the nonlocal mNLS equation are presented. As applications, some soliton solutions, breather solutions, periodic solutions and mixed solutions of the nonlocal mNLS equation are given.
Unraveling cosmological anisotropies within stochastic gravitational wave backgrounds
Authors: Cui Yanou , Kumar Soubhik , Sundrum Raman , Tsai Yuhsin 
Published: October 2023

Abstract
Identifying the anisotropies in a cosmologically sourced stochastic gravitational wave background (SGWB) would be of significance in shedding light on the nature of primordial inhomogeneities.
For example, if SGWB carries isocurvature fluctuations, it would provide evidence for a multi-field inflationary origin of these inhomogeneities.
However, this is challenging in practice due to finite detector sensitivity and also the presence of the astrophysical foregrounds that can compete with the cosmological signal.
In this work, we explore the prospects for measuring cosmological SGWB anisotropies in the presence of an astrophysical counterpart and detector noise.
To illustrate the main idea, we perform a Fisher analysis using a well-motivated cosmological SGWB template corresponding to a first order phase transition,
and an astrophysical SGWB template corresponding to extra-galactic binary mergers, and compute the uncertainty with which various parameters characterizing the isotropic and anisotropic components can be extracted.
We also discuss some subtleties and caveats involving shot noise in the astrophysical foreground.
Overall, we show that upcoming experiments, e.g., LISA, Taiji, Einstein Telescope, Cosmic Explorer, and BBO, can all be effective in discovering plausible anisotropic cosmological SGWBs.

Published: October 2023

Abstract
Mirror energy difference is a key observable in isospin symmetry breaking, containing rich information about nuclear structure. Understanding the mechanisms underlying mirror energy difference is important in nuclear physics. In the present work, we extensively investigated mirror energy difference using ab initio valence-space in-medium similarity renormalization group approach, focusing specifically on

-shell nuclei. The low-lying spectra of Al isotopes and

isotones, together with their mirror nuclei, were calculated, followed by a systematic analysis of the evolution of the mirror energy difference. The results suggest that the large mirror energy difference is mainly caused by the weakly-bound effects and large average occupations of the

orbit. Lastly, we compare the results of our ab initio calculations with shell model results, elucidating the relationship and coherence between these two models.

Different adjustment countermeasures were formulated for oil and water Wells in different strips, and the direction of fine injection and production adjustment was clarified. By using the well focus, structure adjustment and water injection production structure adjustment and so on, effectively reduce the block production decline, control water cut increase speed, and reduce the contradiction between the layers. To realize the purpose of further increase the level of reservoir utilization and improve the development level of A transition belt. At the same time, it provides experience for the injection and production adjustment of the infill well area for the future transition zone.
