Published: July 2024

AbstractThe development of 3D printing technologies and the requirement for more sustainable 3D printing materials is constantly growing. However, ensuring both sustainability and performance of the new materials is crucial to replace current fossil‐based polymers. Here, a bio‐based UV‐curable resin is produced in high yield from gallic acid (GA), a natural polyphenolic compound, by means of rapid and efficient microwave‐assisted methacrylation (5 min heating time and 10 min at 130 °C). The successful microwave‐assisted methacrylation with a high degree of substitution is confirmed by Fourier transform infrared (FTIR) spectroscopy and proton nuclear magnetic resonance spectroscopy. The radical UV‐photopolymerization of the methacrylated gallic acid (MGA) is further investigated by real‐time FTIR and differential scanning photo calorimetry (photo‐DSC) analyses, clearly demonstrating the high photo‐reactivity of MGA. Moreover, the %gel assessment demonstrates the formation of highly insoluble fractions after the UV‐curing, with 98% gel content. The photo‐rheology and rheology support the suitability of MGA for light‐assisted 3D printing. Indeed, a honeycomb and a hollow cube are 3D printed by means of the digital light processing 3D printing technique with high accuracy in a small scale. Finally, the cured‐MGA illustrates high Tg and thermal stability.

AbstractWe prove that for every ultrafilter on there exists a filter on which is ‐Menger and . We show that in the Cohen model there exists such which are tall by using a construction of Nyikos's [10]. These answer a question of Das [2, Problem 7]. We prove that there is a Menger filter of character that is not Hurewicz in the ‐Cohen model where is uncountable regular. This shows that the positive answer to a question of Hernández‐Gutiérrez and Szeptycki [3, Question 2.8] is consistent with . We also study the filter generated by the set of mutually Cohen reals in the ‐Cohen model. We prove that and and every ‐dominating family in the ground model is ‐unbounded in extension. Two questions are posed.

AbstractWe consider the Cauchy problem in for the wave equation with a higher derivative term. We derive sharp growth estimates of the ‐norm of the solution itself for the case of and . By imposing the weighted ‐initial velocity, we can get the lower and upper bound estimates of the solution itself. For the case of , we observe that the ‐growth behavior of the solution never occurs in the ‐framework of the initial data.

Published: July 2024

AbstractWith the development of analytical technologies especially mass spectrometry, metabolomics is becoming increasingly hot in the field of studying antibiotic‐bacterial interactions. On the one hand, metabolomics can reveal metabolic perturbations in bacteria in the presence of antibiotics and expose metabolic mechanisms. On the other hand, through in‐depth analysis of bacterial metabolic profiles, biomarkers and bioactive secondary metabolites with great potential as drug precursors can be discovered. This review focuses on the experimental workflow of bacterial metabolomics and its application to study the interaction between bacteria and antibiotics. Metabolomics improves the understanding of antibiotic lethality, reveals metabolic perturbations in antibiotic‐resistant bacteria, guides the diagnosis and antibiotic treatment of infectious diseases, and aids in the exploration of antibacterial metabolites in nature. Furthermore, current limitations and directions for future developments in this area are discussed.

Authors: Ma Yuxi , Wei Jielin , He Wenshan , Ren Jinghua 
Published: July 2024

AbstractNeutrophil extracellular traps (NETs), which consist of chromatin DNA studded with granule proteins, are released by neutrophils in response to both infectious and sterile inflammation. Beyond the canonical role in defense against pathogens, the extrusion of NETs also contributes to the initiation, metastasis, and therapeutic response of malignant diseases. Recently, NETs have been implicated in the development and therapeutic responses of various types of tumors. Although extensive work regarding inflammation in tumors has been reported, a comprehensive summary of how these web‐like extracellular structures initiate and propagate tumor progression under the specific microenvironment is lacking. In this review, we demonstrate the initiators and related signaling pathways that trigger NETs formation in cancers. Additionally, this review will outline the current molecular mechanisms and regulatory networks of NETs during dormant cancer cells awakening, circulating tumor cells (CTCs) extravasation, and metastatic recurrence of cancer. This is followed by a perspective on the current and potential clinical potential of NETs as therapeutic targets in the treatment of both local and metastatic disease, including the improvement of the efficacy of existing therapies.
Compact IPD bandpass filter with wide upper stopband based on modified topology for 5G applications
Authors: Zhang Qi , Cao Yazi , Wang Gaofeng 
Published: July 2024

AbstractA compact bandpass filter (BPF) with wide stopband performance is proposed and implemented on Si‐based integrated passive device (IPD) technology. A modified topology consisting of a novel Pi‐section and two capacitors are introduced in this BPF. The Pi‐section topology can achieve a band‐pass performance and generate four transmission zeros out‐of‐band. These two capacitors can improve the in‐band matching and also widen the stopband. The proposed BPF with a compact size of 1.0 mm × 0.5 mm × 0.3 mm is fabricated using Si IPD technology and measured by on‐wafer probing. It shows that the insertion loss is less than 1.75 dB, the return loss is better than 18 dB in the 5G band, and the upper stopband suppression level is better than 17.5 dB up to 18 GHz. The simulated and measured results of the proposed BPF are in reasonably good agreement.

AbstractBackgroundExercise intensity is a key component of an exercise prescription. This meta‐analysis aimed to investigate the treatment effect of different exercise doses on fibromyalgia syndrome.MethodsPubMed, Embase, Web of Science, and the Cochrane Library were searched from their inception until 29 December 2023. The studies were subjected to screening using a 2‐phase approach by 2 independent reviewers. Reference lists of the included studies were manually searched. Two independent reviewers extracted information regarding the origin, characteristics of study participants, eligibility criteria, characteristics of interventions, outcome measures, and main results using a pre‐defined template.ResultsThis meta‐analysis encompassed a total of 19 randomized controlled trials comprising 857 patients. Compared with the low compliance/uncertain group according to ACSM, the high compliance group showed better effectiveness in general condition improvement (SMD: −1.15 > −0.71), pain relief (SMD: −1.29 > −1.04), sleep quality enhancement (SMD: −1.66 > −1.08), and fatigue relief (SMD: −1.72 > −1.32). However, there was no difference in the improvement of mental health between the two groups (SMD: −0.93 > −0.92).ConclusionCompared to the ACSM group with compliance uncertainty (<70%), the high compliance group showed improvement in general conditions, pain, sleep quality, and fatigue. However, there was no difference in terms of mental health.

Duchenne muscular dystrophy (DMD) is a progressive X‐linked neuromuscular disorder caused by the absence of functional dystrophin protein. In addition to muscle, dystrophin is expressed in the brain in both neurons and glial cells. Previous studies have shown altered white matter microstructure in patients with DMD using diffusion tensor imaging (DTI). However, DTI measures the diffusion properties of water, a ubiquitous molecule, making it difficult to unravel the underlying pathology. Diffusion‐weighted spectroscopy (DWS) is a complementary technique which measures diffusion properties of cell‐specific intracellular metabolites. Here we performed both DWS and DTI measurements to disentangle intra‐ and extracellular contributions to white matter changes in patients with DMD. Scans were conducted in patients with DMD (15.5 ± 4.6 y/o) and age‐ and sex‐matched healthy controls (16.3 ± 3.3 y/o). DWS measurements were obtained in a volume of interest (VOI) positioned in the left parietal white matter. Apparent diffusion coefficients (ADCs) were calculated for total N‐acetylaspartate (tNAA), choline compounds (tCho), and total creatine (tCr). The tNAA/tCr and tCho/tCr ratios were calculated from the non‐diffusion‐weighted spectrum. Mean diffusivity (MD), radial diffusivity (RD), axial diffusivity (AD), and fractional anisotropy of water within the VOI were extracted from DTI measurements. DWS and DTI data from patients with DMD (respectively n = 20 and n = 18) and n = 10 healthy controls were included. No differences in metabolite ADC or in concentration ratios were found between patients with DMD and controls. In contrast, water diffusion (MD, t = −2.727, p = 0.011; RD, t = −2.720, p = 0.011; AD, t = −2.715, p = 0.012) within the VOI was significantly higher in patients compared with healthy controls. Taken together, our study illustrates the potential of combining DTI and DWS to gain a better understanding of microstructural changes and their association with disease mechanisms in a clinical setting.
From Colonial Order to Decolonial Future: Colonial Mimesis and Identity among the Papua Besena Movement
Authors: Wu Ming‐Jen 
Published: July 2024

ABSTRACTDuring the 1970s and 1980s, a nationalist movement called Papua Besena emerged in Papua New Guinea. On the one hand, the group believed that the Papuan people were neglected by Australian colonisation and campaigned for Papuan sovereignty, either by creating an independent state or joining Australia as a state. On the other hand, as some scholars and politicians have pointed out, Papua Besena's rhetoric of colonial neglect failed to appreciate that Papuan people received more investment in colonial economic development, training, and infrastructure than most Papua New Guineans due to their proximity to the colonial centre. The Australian colonisation of the territories also changed due to pressure from the United Nations visiting mission. Yet despite the Papuan people's access to development, they still felt neglected and humiliated being so close to the colonial centre. To answer this paradox, the concept of mimesis, particularly the idea of colonial mimicry and mimesis as a source of identity, might shed new light on the political history and consciousness of Papuans. This paper suggests that Papuans' access to space, training, and positions was restricted in and around Port Moresby. Many Papuans took up the colonial moral order and mimicked the colonial perspective visible in the capital, projecting it into their decolonial future and their relationships with New Guineans and Australia. In other words, the Papuans' proximity to the colonial space and process contributed to their experiences of neglect and their identity simultaneously.

AbstractSickle cell disease (SCD) and systemic lupus erythematosus (SLE) are two uncommon disorders each characterized by multisystemic manifestations. Individuals with SCD exhibit abnormalities in the complement pathway, which may predispose patients to develop autoimmune disorders such as SLE. As many manifestations of SLE mimic those of SCD, diagnosis and therapeutic management of SLE in a patient with known SCD may be delayed. In this study, we describe our institutional experience of diagnosing and managing concomitant SCD and SLE. We offer insights into the complex interplay between these conditions to enhance early recognition and effective management of concurrent SCD and SLE.

Published: July 2024

AbstractNano‐hydroxyapatite (nano‐HAP)/poly (l‐lactic acid) (PLLA) bone scaffold is expected to overcome the deficiencies and achieve the complementary advantages of individual constituents, but the weak interfacial bonding due to their thermodynamic incompatibility is detrimental to the mechanical properties. Herein, the PLLA chains were grafted onto nano‐HAP with 3‐aminopropyltriethoxysilane (KH550) as a coupling reagent to enhance the interfacial bonding with PLLA. Specifically, the silicon hydroxyl group produced by KH550 hydrolysis could form covalent bonding with the hydroxyl group of nano‐HAP, and the amino group of KH550 initiated the ring‐opening polymerization of l‐lactide monomers to graft PLLA chains onto nano‐HAP more effectively, leading to a higher grafting ratio of 16.7% compared with 7.2% in direct grafting without KH550 modification. Consequently, the tensile and compressive strength of the modified nano‐HAP/PLLA scaffold were improved by 40.8% and 59.5% enhancement due to the enhanced interfacial bonding in the composite scaffold, respectively, compared to the original nano‐HAP/PLLA scaffold. Additionally, the bone scaffold was conducive to cell adhesion and proliferation, making it an ideal candidate for bone defect repair.Highlights
Amino‐functionalized nano‐HAP boosted the grafting efficiency of PLLA chains.
Interfacial bonding between nano‐HAP and matrix was enhanced.
Bone scaffold showed better mechanical properties and benign cytocompatibility.
Inorganic–organic polymer networks derived from a cyclic siloxane tetrafunctional glycidyl ether resin

Published: July 2024

AbstractA tetrafunctional glycidyl ether cyclic siloxane epoxy resin (TGTS) has been synthesized, characterized and cured with four aromatic amine hardeners: 1,3‐phenylenediamine (PDA), diethyltoluenediamine (DETDA), 4,4‐diaminodiphenylmethane (DDM) and 1,3‐bis(4‐aminophenoxy)benzene (APB). Each of the cured networks produces transparent and homogeneous networks, although when TGTS is cured with DETDA, reduced compatibility led to lower epoxide consumption, a more heterogenous microstructure and deleterious effects upon properties. Reduced miscibility of DETDA significantly impacts the chemical structure and microstructure of the network, resulting in significant reductions in thermal and mechanical properties but higher UV‐A transmission. The PDA‐, APB‐ and DDM‐cured networks conversely were more miscible and display properties typical of organic–inorganic hybrid networks, such as good mechanical properties at ambient and sub‐ambient temperatures, comparatively high glass transition temperatures, improved resistance to oxidation and lower UV‐A transmission. © 2024 The Author(s).

Published: July 2024

AbstractFusarium head blight (FHB; caused by Fusarium graminearum) is a destructive disease of wheat (Triticum spp.), barley (Hordeum vulgare), rye (Secale cereale L.), and triticale (×Triticosecale Wittmack) not only reducing their yield but also contaminating the grain with mycotoxins such as deoxynivalenol (DON). Developing varieties with genetic resistance is integral to successfully manage FHB. Triticale acreage worldwide is steadily increasing. However, the genetic diversity of triticale for FHB resistance is not well characterized. In the present study, a sequential screening of a set of winter triticale accessions from a global collection was done for their type‐2 FHB resistance and DON accumulation. In the first‐year screening, 298 triticale accessions were tested for FHB in an artificially inoculated, misted‐field nursery with high inoculum density. Most of the triticale accessions were susceptible to FHB, and only 8% of the accessions showed resistance in the field nursery screening. Next, the 24 resistant accessions identified in the nursery screening were tested for 2 years in greenhouse and 17 accessions showed significantly lower FHB severity in Year 2 and/or Year 3. These 17 resistant accessions were further tested for their FHB severity and DON accumulation in Year 4 in greenhouse and for DON accumulation in Year 5 in the field FHB nursery. Eight accessions showed significantly lower FHB severity and nine accessions showed DON accumulation of less than 1 mg/kg in Year 4 greenhouse testing. Eleven accessions had significantly lower DON concentration than the susceptible check in the Year 5 field screening. The resistant accessions common across all years identified in the study can be used for enhancing FHB resistance and reducing DON accumulation in triticale breeding programs.

Authors: Shen Saikang , Tampieri Francesco , Garcia Maria C. , Canal Cristina 
Published: July 2024

AbstractPlasma jets, crucial atmospheric pressure sources in biomedical applications, generate reactive species in liquids, with electrical fields playing a significant role, as variations in pulse rise times and durations in dielectric barrier discharges yield diverse effects. This study presents a novel nanosecond pulse plasma jet. Here, investigations with phosphate‐buffered saline and Ringer's saline elucidate critical parameters influencing species generation, such as treatment time and gas flow rate. Results showed increasing concentrations of H2O2 and NO2− over time, with NO2− degrading faster in Ringer's saline due to acidification. The nanosecond pulse jet exhibits superior energy efficiency than conventional jets, laying the groundwork for optimizing species generation and studying electrical field effects in future biological works.
Solvent Vapor Annealing and Plasma Treatment Stabilize Silver Nanowire Layers
Authors: Grammes Thilo , Maurer Johannes , González‐García Lola , Kraus Tobias 
Published: July 2024

AbstractSilver nanowires (AgNW) find use in transparent conductive electrodes with applications in solar cells, touch screens, and wearables. Unprotected AgNW are prone to atmospheric corrosion and lose conductivity over time. Known passivation techniques either require submersion of pre‐deposited AgNW in liquid compounds or the modification of AgNW inks prior to deposition, which alters viscosity and complicates deposition. Here, new possibilities for stabilization of pre‐deposited AgNW networks without need for submersion are explored. It is demonstrated that AgNW networks can be stabilized either by argon or hydrogen plasma treatment or by solvent vapor annealing with ethanol, methanol, or ethyl acetate. These treatments yielded stable electrical resistance over at least nine weeks, whereas untreated or thermally annealed AgNW layers quickly lost conductivity. The potential of solvent vapor annealing is further explored by demonstrating a new processing technique for stable polymer matrix composites containing AgNW. Co‐deposited layers of AgNW with polystyrene microbeads are annealed in ethyl acetate vapor to stabilize the AgNW while at the same time merging polymer beads into a closed film around the AgNW. The resulting composites maintained stable resistance and transmittance for at least seven weeks.

AbstractBACKGROUNDUnmanned aerial vehicles (UAVs) for pesticide application show promising potential in tobacco pest management. However, the impact of flight parameters on spray efficacy requires further investigation. Three field experiments were conducted from the rosette to the maturation stage of tobacco to systematically assess spray efficacy under varying flight heights, speeds, and application volumes. Using a multi‐index weight analysis method, optimal operational parameter combinations for different tobacco growth stages were evaluated and compared with backpack electric sprayers.RESULTSFor the rosette stage, the recommended parameter is a flight speed of 5 m s−1, a flight height of 2 m, and a liquid application volume of 30 L hm−2; during the vigorous growth stage, the suggested parameter includes a flight speed of 3 m s−1, a flight height of 2 m, and a liquid application volume of 22.5 L hm−2. In the maturing stage, optimal parameter consists of a flight speed of 3 m s−1, a flight height of 3.5 m, and a liquid application volume of 30 L hm−2. Furthermore, UAV spraying achieves higher droplet deposition on both sides of tobacco leaves compared to traditional electric backpack sprayers.CONCLUSIONSAdjusting UAV spraying parameters for different tobacco growth stages is crucial. These results can provide the methods for the precise control technology of tobacco pests at different growth stages. © 2024 Society of Chemical Industry.
