Published: July 2023

To further unlock kraft lignin's potential in material applications, we show that tight control can be achieved over a key physicochemical lignin parameter, its Tg, which largely determines, and serves as proxy for, the properties of lignin-derived thermoset materials.
Kaempferol improves acute kidney injury via inhibition of macrophage infiltration in septic mice

Published: July 2023

Abstract
Sepsis contributes to life-threatening circulatory and organ dysfunction by dysregulating the host response to infection in critically ill patients. Treatment in an Intensive Care Unit (ICU) can improve the survival of patients who suffer from severe sepsis, but sepsis-associated acute kidney injury (SAKI) is still one of the main causes of death. The existing treatment is mainly focused on controlling microorganism induced infections by using drugs, such as ulinastatin and glucocorticoid. Also, it is well documented that kaempferol, a flavonoid derived from plant sources, improves septic mouse survival via anti-inflammatory response. However, the mechanism of anti-inflammatory response mediated by this flavonoid compound was little known. This study aims to demonstrate the mechanisms of inflammatory response regulated by kaempferol treatment during sepsis. We perform cecal ligation and puncture (CLP) injury as a sepsis mouse model and evaluate organ injury in sepsis. The molecular (qRT-PCR and Western Blot) and cellular profiling (IHC staining and Flow Cytometry) of the immune responses illustrates that kaempferol decreases the expression of adhesion molecular genes (ICAM-1 and VCAM-1) and monocyte chemoattractant protein-1 (MCP-1), thereby inhibiting F4/80+ macrophages infiltration in CLP-induced acute kidney injury. Our data suggested that kaempferol alleviates acute kidney injury via regulating F4/80+ macrophages infiltration in CLP-induced acute kidney injury.

Published: July 2023

AbstractInitiatives to minimise battery use, address sustainability, and reduce regular maintenance have driven the challenge to use alternative power sources to supply energy to devices deployed in Internet of Things (IoT) networks. As a key pillar of fifth generation (5G) and beyond 5G networks,IoT is estimated to reach 42 billion devices by the year 2025. Thermoelectric generators (TEGs) are solid state energy harvesters which reliably and renewably convert thermal energy into electrical energy. These devices are able to recover lost thermal energy, produce energy in extreme environments, generate electric power in remote areas, and power micro‐sensors. Applying the state of the art, the authorspresent a comprehensive review of machine learning (ML) approaches applied in combination with TEG‐powered IoT devices to manage and predict available energy. The application areas of TEG‐driven IoT devices that exploit as a heat source the temperature differences found in the environment, biological structures, machines, and other technologies are summarised. Based on detailed research of the state of the art in TEG‐powered devices, the authors investigated the research challenges, applied algorithms and application areas of this technology. The aims of the research were to devise new energy prediction and energy management systems based on ML methods, create supervised algorithms which better estimate incoming energy, and develop unsupervised and semi‐supervised approaches which provide adaptive and dynamic operation. The review results indicate that TEGs are a suitable energy harvesting technology for low‐power applications through their scalability, usability in ubiquitous temperature difference scenarios, and long operating lifetime. However, TEGs also have low energy efficiency (around 10%) and require a relatively constant heat source.
A novel sea clutter suppression method based on SVD‐FRFT at low signal‐to‐clutter ratio
Authors: Cheng Qingyun , Wu Xiaochuan , Zhang Xin , Yang Qiang 
Published: July 2023

AbstractThe target and sea clutter Doppler domains frequently overlap due to the frequent passage of slow ship targets through the sea clutter zone. In this letter, a novel sea clutter suppression method is suggested as a solution to this issue, whose key is a novel singular value zeroing criterion guided by the search results of two‐dimensional spectral peaks. Verified by simulations, the method proposed can improve signal‐to‐clutter ratio (SCR) from −8 to 41 dB in the frequency domain and be more effective than the conventional SVD‐FRFT (a method for joint application of singular value decomposition and fractional Fourier transformer) and improved SVD‐FRFT.
Modulation signal recognition based on feed‐forward attention mechanism
Authors: Wang Biao , Zhang Shizhen , Zhu Yunan 
Published: July 2023

AbstractIn recent years, research on modulated signal recognition using deep learning (DL) has achieved remarkable success, allowing automatic modulation recognition (AMR) to play a crucial role in modern communication systems. The emergence of the attention mechanism has then rapidly led to a wide range of applications in image classification and speech recognition, which proves the effectiveness of the attention mechanism. In this paper, the authors propose a network model feed‐forward Attention mechanism with Residuals networks and Long Short‐Term Memory (RLADNN) based on feed‐forward attention mechanism with Residuals networks (Resnet) and Long Short‐Term Memory (LSTM), which takes the advantage that the Attention mechanism can effectively solve some long‐term memory problems in [−20:18] signal‐to‐noise ratio (SNR) for the recognition of 11 modulated signals with different SNR, and effectively improves the recognition rate.
A compact printed hybrid‐mode antenna for dual‐band dual‐sense circular polarisation
Authors: Fujimoto Takafumi , Guan Chai‐Eu 
Published: July 2023

AbstractA compact printed hybrid‐mode antenna for dual‐band dual‐sense circular polarisation (CP) has been proposed. To achieve dual‐band dual‐sense CP, a hybrid mode produced by an L‐shaped element and a loop element is used. In the lower frequency band, the left‐handed CP is radiated by a vertical electric field from the L‐shaped element and a horizontal electric field from the loop element. In the higher frequency band, the right‐handed CP is radiated by a horizontal electric field from the L‐shaped element and a vertical electric field from the loop element. Both the L‐shaped and the loop elements produce resonances in the lower and higher frequency bands. The operational principle for dual‐band dual‐sense CP is clarified using the simulated orthogonal components of the electric fields and the simulated electric current distributions. Parametric studies are discussed in the design procedure. The simulated and measured input reflection coefficient, axial ratio, absolute gain, and radiation pattern are presented. The measured bandwidths of −10dB‐input reflection coefficient with a 3dB‐axial ratio are 2.37–2.55 GHz (7.32%) in the lower frequency band and 3.38–3.70 GHz (9.04%) in the higher frequency band. The antenna size is 0.0741λ2.452 and 0.151λ3.52 (λ f is a wavelength at f GHz).
Third harmonic injection control for co‐phase traction power supply system using direct AC/AC full‐bridge modular multilevel converter
Authors: Tian Ruoning , Wu Xuezhi , Jing Long , Li Jinke , Zhao Haitian , Yan Huiwen 
Published: July 2023

AbstractAs the full‐bridge modular multilevel converter (FB‐MMC) enables direct three‐phase AC voltage to single‐phase AC voltage conversion with good power quality and high voltage level, it is suitable for the co‐phase traction power supply system. However, voltage deviation occurs between arms when the direct AC/AC FB‐MMC operates in equal or similar frequency conditions. To solve this problem, a voltage balancing control based on third harmonic injection of co‐phase power supply system using direct AC/AC FB‐MMC is proposed. With the third harmonic injection, voltage balancing between arms is ensured and the capacity of FB‐MMC is enhanced. The third harmonic voltage is directly obtained from existing signals and the third harmonic current reference is produced by simple proportional‐integral (PI) controller. The effect of the third harmonic currents under different voltage ratios and phase difference is quantitatively analyzed, optimized range of voltage ratio and phase difference are obtained to minimize arm currents increment and reduce overrating of converter currents. In addition, a comparison between the proposed and the conventional control scheme is studied, showing the superior of proposed method in cost and performance. Finally, the effectiveness of the proposed scheme is verified by simulations and experiments.

Aims.We want to study the population of blue horizontal branch (HB) stars in the centres of globular clusters (GC) for the first time by exploiting the unique combination of MUSE spectroscopy and HST photometry. In this work, we characterize their properties in the GCsωCen and NGC 6752.Methods.We use dedicated model atmospheres and grids of synthetic spectra computed using a hybrid LTE/NLTE modeling approach to fit the MUSE spectra of HB stars hotter than 8000 K in both clusters. The spectral fits provide estimates of the effective temperature (Teff), surface gravity (logɡ), and helium abundance of the stars. The model grids are further used to fit the HST magnitudes of the stars, that is, their spectral energy distributions (SEDs). From the SED fits, we derive the average reddening, radius, luminosity, and mass of the stars in our sample.Results.The atmospheric and stellar properties that we derive for the stars in our sample are in good agreement with theoretical expectations. In particular, the stars cooler than ~15 000 K closely follow the theoretical predictions on radius, logɡ, and luminosity for helium-normal (Y= 0.25) models. InωCen, we show that the majority of these cooler HB stars cannot originate from a helium-enriched population withY> 0.35. The properties of the hotter stars (radii and luminosities) are still in reasonable agreement with theoretical expectations, but the individual measurements show a large scatter. For these hot stars, we find a mismatch between the effective temperatures indicated from the MUSE spectral fits and the photometric fits, with the latter returningTefflower by ~3000 K. We use three different diagnostics, namely the position of the G-jump and changes in metallicity and helium abundances, to place the onset of diffusion in the stellar atmospheres atTeffbetween 11 000 and 11 500 K. Our sample includes two stars known as photometric variables; we confirm one to be a bona fide extreme HB object but the other is a blue straggler star. Finally, unlike what has been reported in the literature, we do not find significant differences between the properties (e.g., logɡ, radius, and luminosity) of the stars in the two clusters.Conclusions.We show that our analysis method – combining MUSE spectra and HST photometry of HB stars in GCs – is a powerful tool for characterising their stellar properties. With the availability of MUSE and HST observations of additional GCs, we have a unique opportunity to combine homogeneous spectroscopic and photometric data to study and compare the properties of blue HB stars in different GCs.

Edwardsiella tarda Causing Fishbone Injury Cellulitis Leading to Sepsis in a Case of Hematological Malignancy—A Rare Report and Review of Literature
Authors: Sarathi Sushree , Brahma Anupam , Das Prabodha Kumar , Mahapatra Ashoka , Behera Bijayini 
Published: July 2023

Abstract
Edwardsiella tarda (E. tarda), a gram-negative bacillus, a member of order Enterobacterales, is typically a fish pathogen frequently isolated from fresh and brackish water environments. It is very rarely implicated in human infections such as gastroenteritis (most common), cellulitis, gas gangrene, hepatobiliary infections, peritonitis, empyema, and meningitis. Bacteremia/sepsis caused by E. tarda can be fatal in humans, although very rare (<5%). To date, very few cases of E. tarda sepsis have been reported worldwide including India. We report a rare case of cellulitis caused by E. tarda following fishbone injury in a patient with underlying hematological malignancy leading to sepsis.
Recurrent Nasopharyngeal Carcinoma and the Role of Surgery
Authors: Saraswathula Anirudh , London Nyall R. 
Published: July 2023

AbstractRecurrent nasopharyngeal carcinoma (rNPC) presents unique challenges as reirradiation comes with significant treatment-related morbidity in swallowing, middle ear function, and large-vessel integrity. Advances in endoscopic technology have made surgery for rNPC an increasingly viable option for select patients and may play a role in providing a better quality of life to patients with this challenging disease. In carefully selected patients, endoscopic and open surgical approaches may provide comparable disease control while mitigating long-term treatment-related morbidity.

Published: July 2023

Abstract
Background Distal radius fractures are commonly seen among the elderly, though studies examining their long-term outcomes are limited.
Purpose The aim of this study was to describe the 5-year trajectory of recovery of distal radius fractures treated with open reduction and internal fixation (ORIF).
Methods Patients with distal radius fractures (AO/OTA 23.A-C) treated by ORIF were prospectively studied. Patient-Rated Wrist Evaluation (PRWE) score was measured at baseline (preinjury recall) and postoperatively at 6 months, 1 year, and 5 years. Clinically relevant change in PRWE score was assessed using the minimal clinically important difference (MCID).
Results A total of 390 patients were included, of which 75% completed 5-year follow-up. Mean baseline PRWE score was 1.25 (standard deviation, SD: 2.9). At 6 months, mean PRWE score was at its highest up to 20.2 (SD: 18.4; p < 0.01). A significant improvement in mean PRWE score was observed at 1 year down to 15.2 (SD: 17.6; p < 0.01); 44% of patients were still one MCID outside of their baseline PRWE score at 1 year. Further significant improvement in mean PRWE score occurred at 5 years down to 9.4 (SD: 13.4; p < 0.01); 29% of patients remained one MCID outside of their baseline PRWE score at 5 years.
Conclusion Recovery after ORIF for distal radius fractures showed significant worsening after surgery, followed by significant improvements up to 1 year and between years 1 and 5, albeit to a lesser extent. Statistically and clinically relevant wrist pain and disability persisted at 5 years. Future research should examine different treatment modalities and include a nonoperative treatment arm for comparison.

Counter-terrorism training for business in UK crowded places: is the desire for quantity to the detriment of quality?
Authors: Aplin Dylan , Brooke Rogers M. 
Published: July 2023

Abstract
There is a dearth of evidence to indicate the effectiveness of counter-terrorism (CT) training for workers in crowded places to achieve their objectives of preventing attacks, helping staff to cope in a critical incident and then return to some form of normality afterwards. This study conducted semi-structured interviews (N = 23) of key stakeholders involved in devising, commissioning, and delivering CT programmes. It was found that lack of regard for adult learning theory, the skills and experience that particularly security officers bring to sessions and a complete absence of structured evaluation mean that the desire to increase the quantity of sessions delivered was to the detriment of quality. A series of recommendations are made to improve the future development and delivery of CT programmes to improve resilience.
Nucleation of helium in pure liquid lithium
Authors: Álvarez-Galera Edgar , Martí Jordi , Mazzanti Ferran , Batet Lluís 
Published: July 2023

Tritium self-sufficiency in fusion nuclear reactors will be based on the neutron capture by lithium in the so-called breeding blankets of the reactor, a nuclear reaction that will produce helium along with tritium. The low solubility of helium in liquid metals could cause the eventual formation of helium bubbles, which may have a negative impact on the performance of the breeding blanket in a way that has yet to be fully understood. In this work, we provide deep insight into the behavior of lithium and helium mixtures at experimentally operating conditions (800 K and pressures between 1 and 100 bars) using a microscopic model suitable to describe the interactions between helium and lithium at the atomic level, in excellent agreement with available experimental data. The simulations predict the formation of helium bubbles with radii around 10 Å at ambient pressure with surface tension values in the range of 0.6–1.0 N/m. We also report the cohesive energies of helium and the work of formation of the cluster of atoms, as well as a quantitative estimation of the Hildebrand and Kumar cohesion parameters. Our results indicate that the segregation between He and Li atoms is strong, and once a bubble is formed, it never dissociates.

The nonadiabatic interactions between the C̃ state and neighboring electronic states of SO2 have attracted much attention; however, the predissociation mechanisms are not yet completely understood. In this work, the predissociation dynamics of SO2 via its C̃ state have been investigated at λ = 193–201 nm by using the time-sliced velocity map ion imaging technique. The translational energy distributions and the branching ratios of the O(3PJ=2,1,0) spin–orbit products at six photolysis wavelengths have been acquired. The SO(3Σ−) product population gradually decreases in v = 0 and increases in v = 2 as the photolysis wavelength decreases. The branching ratios of O(3P J=2,1,0) products are almost similar at most wavelengths, except at 194.8 nm. Our data suggest that the predissociation between 193 and 201 nm is via an avoided crossing between the C̃ state and the repulsive triplet 23A′ state. The state-to-state dynamical pictures shown in this work provide a rigorous test of the potential energy surfaces (PESs) of the SO2 and the nonadiabatic couplings between these PESs.
Give it to her

Abstract
Pornography is commonly criticized for allegedly representing and promoting sexual dominance of men over women.
Studies have shown varying results, with no scientific consensus reached on the matter. To contribute to the discussion with
empirical discourse analysis evidence, I examine the linguistic choices reflected in a corpus of erotic novels to test whether
there are gendered patterns of agency in the representation of sexual interactions. The construal of prominence is correlated to
the notion of agency to find which participant specifies the trajector status and agent role in every relational expression.
Results show that male participants take prominence over females in an overwhelming majority of the cases, while expressions with
plural agency are marginal. The approach of this paper, combining cognitive grammar with linguistic participation roles, provides
comprehensive and realistic results by attempting to operationalize agency as the linguistic expression of a particular cognitive
pathway.
Reciprocal constructions
Authors: Yakpo Kofi 
Published: July 2023

Abstract
This study analyzes the borrowing of Dutch reciprocal pronouns in a corpus of primary field data of Sranan,
Sarnami, and Surinamese Javanese, three languages of Suriname. The expression of reciprocity in relevant African and Asian
substrates of the languages under study is also presented and discussed. I suggest cognitive and sociolinguistic explanations for
the preference of Dutch-sourced reciprocal pronouns during multilingual contact. The three languages show convergent borrowing
processes favoring the dedicated Dutch reciprocal pronoun over ‘scattered’ native strategies. Further, Suriname is a hierarchical
post-colonial language ecology in which borrowing proceeds mostly in one direction, either directly from Dutch, or from Dutch via
Sranan. The parallel multilingual trajectory of contact-induced change in the expression of a complex notion like reciprocity
showcases the attractiveness for borrowing of forms and structures with transparent relations between form and content.
