Published: January 2025

AbstractSeed shattering, that is, the loss of seeds at ripening stage shortly before or during seed harvest, is strongly reducing seed yield in Italian ryegrass (Lolium multiflorum Lam.). The aim of this study was to evaluate the possibility to reduce seed shattering within breeding germplasm via recurrent phenotypic selection on spaced plants. Starting from a founder population of 300 plants not previously selected for seed shattering, two cycles of phenotypic selection for high and low seed shattering were performed based on spaced plants. The resulting five populations with different levels of selection for seed shattering (selected once or twice for low seed shattering, selected once or twice for high seed shattering, and no [random] selection) were phenotyped in plot trials with two harvesting dates (early and late). Seed shattering was highest in the population selected twice for increased seed shattering (7.92% for early and 28.44% for late harvesting), followed by the population selected once for increased seed shattering (7.34% early, 21.56% late), the non‐selected population (6.12% early, 20.22% late), the population selected once for decreased seed shattering (4.13% early, 16.73% late), and the population selected twice for decreased seed shattering (2.41% early, 9.31% late). Selecting twice for low seed shattering resulted in a reduction of seed shattering by 10.91 percentage points at late harvest when compared to the non‐selected population. Thus, recurrent phenotypic selection on spaced plants is appropriate to efficiently reduce seed shattering and to increase seed yield in sown plots, which is highly relevant for seed production.

AbstractTo commercialize perovskite solar cells and advance beyond lab‐scale comparisons, understanding large‐area film formation using slot‐die coating is essential to improve film homogeneity. Adding high‐boiling‐point solvents like N‐methyl‐2‐Pyrrolidone (NMP) to the perovskite ink extends film′s processing window, but the effects of varying NMP levels on gas‐quenched slot‐die coatings remain unclear. This article examines how different NMP ratios impact film quality, showing that a moderate amount of NMP as a co‐solvent reduces defects, as observed through photoluminescence, hyperspectral absorbance, and back‐illuminated optical absorptions. However, the decreased vapor pressure with the addition of NMP impairs crystallization and film coverage, highlighting the need for balanced amounts. X‐ray diffraction (XRD) and scanning electron microscopy (SEM) analysis indicate that the most volatile option tested at Dimethylformamide (DMF) : NMP ratio of 8 : 1 yields the most homogeneous and compact films. Slot‐die‐coated devices fabricated with this optimized ratio were subsequently compared with using NMP as an additive to increase the volatility of the perovskite inks further. The additive method demonstrates improved performance and uniformity, suggesting that minimizing high‐boiling‐point solvents to maintain ink volatility supports effective large‐area coatings and fabrication of perovskite solar cells. Furthermore, this article provides insights on important metrics to narrow down suitable perovskite inks for large‐area coatings.

AbstractHereditary diffuse gastric cancer (HDGC) is an autosomal dominant cancer caused by CDH1 mutation. HDGC causes multiple signet ring cell carcinomas (SRCCs) throughout the stomach. Few reports exist on the endoscopic findings during screening endoscopy, leading to the diagnosis of HDGC in its early stages. Recently, a new image‐enhancement endoscopy technique, texture and color enhancement imaging (TXI), has been developed to improve the visibility of early gastric cancer. To the best of our knowledge, the use of TXI leading to HDGC diagnosis has not been reported. In this report, TXI contributed to the diagnosis of HDGC, and the patient was treated with total gastrectomy. A 27‐year‐old woman with a family history of gastric cancer underwent esophagogastroduodenoscopy, which revealed two pale lesions in the lower body of the stomach. Histological examination of the biopsy specimen revealed SRCC and the patient was referred to our hospital for treatment. Multiple lesions were found in the lower body using TXI, and a targeted biopsy confirmed other SRCCs. We suspected her disease to be HDGC, and the patient underwent a total gastrectomy. Histopathology showed multiple SRCCs (>60), but no lymph node metastases. Genetic testing revealed CDH1 mutations. The final pathological stage of the tumor was pT1a(m) N0M0 Stage I. TXI may be helpful in detecting multiple SRCCs in patients with HDGC. Endoscopists should be aware of HDGC, and careful investigation of the entire stomach is required for patients with diffuse‐type gastric cancer before treatment.

ABSTRACTPredation plays an important role in animal evolution by selecting for antipredator adaptations. Antipredator color adaptations include conspicuous spots, which are believed to provide protection by deflecting attacks to harmful or peripheral body parts, deimatic signaling, or as conspicuous warning coloration. The utility of antipredator signals is context‐dependent and may be influenced by the environment. In this study, we investigated the selective forces acting on the evolution of conspicuous spots on velvet ants (Mutillidae: Dasymutilla). We tested whether conspicuous spots in 80 species of velvet ants evolved in (i) forest‐dwelling species, (ii) habitat‐generalist species, or (iii) species predated by diverse birds and frogs. Results show that conspicuous spots are more likely to evolve in forest‐dwelling species and in areas with more canopy cover, whereas species inhabiting open areas and deserts tend to lose them. Moreover, taxa with conspicuous spots transition between open and forested habitats less often. Spot presence was not associated with predator diversity. We suggest that spots in velvet ants require complex visual environments to be effective, which may limit their habitat occurrence. In simpler environments, carrying conspicuous spots could be costly due to increased exposure to visual predators.

Published: January 2025

ABSTRACTObjectiveEating disorders (ED) typically emerge in adolescence, a critical period for brain development and peer bonding. Interpersonal difficulties—particularly social anxiety—frequently co‐occur with ED. Oxytocin is a neuropeptide that modulates social cognition and linked to prosocial effects. To date, no study has investigated oxytocin's effects on negative interpretation bias toward ambiguous information in adolescents with ED.MethodsForty‐eight female adolescents aged 16 to 17 years with and without EDs took part in a placebo‐controlled, double‐blinded, randomised, crossover trial investigating the effects of 24 IU intranasal oxytocin on negative interpretations of ambiguous scenarios. Participants and controls were tested twice, approximately one week apart.ResultsContrary to hypothesis, oxytocin increased negative interpretations overall (p = 0.019, large effect). Adolescent females with AN or BN made more negative interpretations than controls when presented with ambiguous information. There was no group effect for those who reached or did not reach threshold on an autism screen.ConclusionsThis study suggests adolescents with EDs interpret ambiguous information more negatively than controls and that oxytocin administration amplifies negative responses to ambiguity in adolescent females, including in controls. Research tools that effectively identify these biases would help to widen the scope of ED treatments for adolescents.

ABSTRACTThis study includes the synthesis of a novel fullerene composite for hydrogen storage application. In the first step of this work the fullerene of the type C60 was used to prepare its composite with selenium nanoparticles (Se Nps). The synthesis method was novel as it includes the synthesis of fullerene‐Se nanocomposite via ultrasound at 750 W using ascorbic acid as reducing agent to convert selenium ion into selenium nanoparticles. Different techniques (XRD, SEM, TEM) were used to diagnose the composition, size and morphology of the prepared composite. The characterization results from SEM and TEM demonstrate the formation of sphere‐like structures decorated on rod nanoparticles, proving the formation of required nanocomposite. Moreover, the XRD pattern demonstrates the existence of fullerene and selenium nanoparticles peaks with high purity. The important of this nanocomposite was comprehended from the using it in the hydrogen energy application. The study was conducted at 77, 173, 223 and 273 K and 0–90 bar and the study proves the physical adsorption at 55 bar as it showed 4.1 wt% storage with enthalpy of 0.13 KJ/(mol H2) and entropy of 0.70 J/mol H2.

ABSTRACTWith the growth of cloud computing and the popularity of electronic health records (EHR), more and more patients and hospitals are uploading EHR to the cloud for storage, retrieval and organization. Due to the privacy of EHR, cloud‐based EHR systems need to protect data security and provide access control, and attribute‐based encryption (ABE) is the appropriate technology. Nevertheless, traditional single‐center ABE schemes do not conform to the collaborative scenario of electronic health care, and some of them do not support real‐time attribute update. Consequently, this paper proposes a lightweight CP‐ABE scheme for EHR over cloud based on blockchain and secure multi‐party computation (LCBS). First, we introduce the model of multi‐authority and innovatively apply secure multi‐party computation to initialize the system, which maintains normal system operation while the power is decentralized. Second, we deploy a blockchain suitable for EHR systems to record the users' key information, assisting multiple entities to verify the key at different stages and protecting the EHR from illegal acquisition. In addition, our scheme supports lightweight attribute update, which requires small amount of computational overhead to achieve instant attribute update. Finally, through formal security analysis and simulation experiments of the LCBS system, it is shown that our scheme guarantees data security and improves computing efficiency.

Published: January 2025

ABSTRACTThe inherent complexity and the critical nature of data privacy in IoT networks necessitate rigorous validation of privacy mechanisms to preempt vulnerabilities and ensure compliance with security standards. This research article extends the concept of the SDN‐enabled Consumer‐Centric Content Delivery Network (CCDN) model for the IoT by introducing a rigorous mathematical framework to formalize the dialogues integral to user privacy and data integrity. With the help of a comprehensive mathematical formulation, the research captures the dynamics of credential exchange and user interactions within the CCDN architecture. To ensure the robustness of the proposed model, this research employs formal verification techniques to validate the correctness and security properties of the mathematical formulation. Furthermore, the research conducts an extensive simulative analysis to evaluate the performance of the CCDN architecture under various operational conditions. This analysis encompasses aggregate analysis, amortized analysis, and scalability analysis, focusing on critical performance metrics such as latency, packet loss ratio, and throughput. The results demonstrate that the implemented CCDN model maintains user privacy and personalization for content delivery in scalable IoT environments. This work lays the groundwork for future research in secure and efficient content delivery systems, addressing the growing demands of IoT applications while ensuring user‐centric privacy and data protection.
Beyond Traditional RFID: Unveiling the Potential of Wi‐Fi, 5G, Bluetooth, and Zigbee for Backscatter Systems
Authors: El Mattar Sara , Baghdad Abdennaceur 
Published: January 2025

ABSTRACTTraditional RFID systems rely on dedicated readers, often expensive and bulky, hindering their widespread deployment. This paper proposes an alternative RFID system that leverages ubiquitous radio sources—Wi‐Fi, 5G, Bluetooth, and Zigbee—to replace dedicated readers. Our system employs backscatter communication, where RFID tags modulate reflected signals from these readily available sources to transmit data. We investigate the feasibility and performance of this approach through Matlab simulator. Our results show that 802.11ax at 2.45 GHz exhibits the best symbol error rate, followed by 802.11n at the same frequency. However, 5G, Bluetooth, and Zigbee signals demonstrate lower performance even at high signal‐to‐noise ratios. To address this, we introduce error correction coding techniques (BCH and RS) that significantly improve communication reliability. Utilizing these codes, our system achieves a communication range of up to 1 m. This finding highlights the potential of ubiquitous radio sources as a viable alternative to dedicated RFID readers, opening doors for various applications.
Relationship Between Food Addiction, Night Eating Syndrome and Depression Level in University Students and Affecting Factors: A Cross‐Sectional Study in Türkiye
Authors: Erem Sinem , Eren Deniz 
Published: January 2025

ABSTRACTFood addiction, night eating, and depression levels alone have been associated with obesity and various chronic diseases in university students, but the relationship of these factors has been rarely mentioned in the literature. This research was conducted to determine the food addiction, night eating, and depression status of university students. The study consisted of 1009 (84.2% female, mean BMI 21.93 ± 3.42 kg/m2, 73.0% normal body weight) university students. Research data were collected using a web‐based questionnaire, which included a personal information form about students' sociodemographic characteristics, nutritional habits and anthropometric measurements (body weight, height), the Yale Food Addiction Scale (YFAS), the Night Eating Questionnaire (NEQ), and Beck Depression Inventory (BDI). Of the students, 15.2% had food addiction, 8.3% had night‐eating syndrome, and 36.2% had moderate depression. Frequency of food addiction and night‐eating syndrome were higher in those with moderate to severe depression and night‐eating syndrome was higher in those with food addiction (p < 0.001). A positive correlation was found between mean YFAS, NEQ, and BDI scores in the general population and both genders (p < 0.001). Furthermore, BMI levels, having received psychological treatment, waking up and eating at night, and depression level increased the likelihood of food addiction, while waking up and eating at night, and depression levels increased the likelihood of night‐eating syndrome. The findings of the study made a significant contribution to the literature in understanding food addiction, night eating, depression levels and their relationship with each other in university students. Multi‐center studies in which the effects of these three factors are examined together should be conducted on different student populations. Students should be given training on healthy nutrition and mental health protection, and their awareness should be raised.

ABSTRACTPunica granatum, commonly known as pomegranate, is a traditional medicinal agent owing to its antiquity. The scientific literature has shown that pomegranate extracts exhibit favorable modulation of diverse signaling pathways. These pathways encompass those implicated in inflammation, angiogenesis, hyperproliferation, cellular transformation, tumorigenesis initiation, and ultimately, a reduction in advanced metastasis and tumorigenesis. Pomegranate extracts in this context can be attributed to their high polyphenol content, which has been observed to possess inhibitory properties toward specific signaling pathways associated with cancer. As a formidable pathology, cancer is the most significant cause of death worldwide after cardiovascular disease. The annual incidence of cancer‐related mortality has increased progressively. Modifying one's dietary patterns, engaging in regular physical exercise, and maintaining an optimal body mass index are three straightforward measures that an individual may undertake to mitigate their susceptibility to cancer. Incorporating diverse vegetables and fruits into one's dietary regimen exhibits promising potential for preventing a minimum of 20% cancer incidence and approximately 200,000 cancer‐related mortalities annually. Vegetables and fruits contain high levels of minerals and phytochemicals, which help alleviate and prevent the harmful effects of cancer. These substances are safe and exhibit minimal toxicity in biological systems. Furthermore, they exhibit antioxidant properties and have garnered extensive approval for their use as nutritional supplements. Pomegranates are used in ancient cultures to prevent and treat various diseases. Extensive research on pomegranate extract, fruit, oil, and juice has revealed promising findings regarding their potential anti‐proliferative, anti‐tumorigenic, and anti‐inflammatory properties through the modification of various signaling pathways related to cancer, thus demonstrating their potential as drugs to prevent and treat cancer. Emerging research indicates that pomegranate can potentially prevent and treat different cancers, including prostate, bladder, breast, skin, lung, and colon cancer.

AbstractBackgroundThe indication of transcatheter aortic valve replacement (TAVR) is becoming more prevalent among younger and lower‐risk patients. However, data on the latest intra‐annular TAVR devices are limited. This study aims to compare the short‐term clinical outcomes of two intra‐annular transcatheter aortic valve replacement (TAVR) devices in Japan: SAPIEN 3 Ultra RESILIA (S3UR) and Navitor.MethodsOf the 286 patients who underwent TAVR between May 2022 and October 2023 at our center, we enrolled 97 consecutive patients who received either S3UR or Navitor. We compared the intraprocedural invasive and echocardiographic hemodynamic assessment and post‐procedural multidetector computed tomography (MDCT).ResultsThe basic characteristics of the 97 patients (median age, 86 years [interquartile range, 81–89 years]) were similar. Technical success, defined by the Valve Academic Research Consortium, was achieved in all cases. Despite a smaller annulus, Navitor demonstrated decreased mean pressure gradient by TTE, 9.2 [7.3–13.6] mmHg versus 7.5 [5.9–9.5] mmHg, p = 0.006; but not by invasive measurement 5.1 [3.4–7.7] mmHg versus 5.3 [3.2–7.9] mmHg, p = 0.986). Discordance between echocardiographic and invasive assessment was more prominent with S3UR. However, severe prosthesis‐patient mismatch was similarly noted between the two devices. Mild paravalvular leak (PVL) (24.5% vs. 54.5%, p = 0.002) was more frequent with the Navitor, despite no moderate‐severe PVL in each group. The incidence of hypoattenuated leaflet thickening (HALT) detected by MDCT was similar between the two groups.ConclusionsBoth intra‐annular valves demonstrated excellent hemodynamic performance with minimal PVL after TAVR. The incidence of HALT in both devices was comparable.

Published: January 2025

ABSTRACTThis research introduces the sheaf attention–based osprey spiking neural network (SA‐OSNN) to optimize the thermal performance of GaAs and GaN high electron mobility transistors (HEMTs), which are critical for radio frequency and microwave circuits due to their excellent electron characteristics. By integrating modified osprey optimization, the SA‐OSNN approach enhances thermal management by dynamically adjusting model parameters in response to changing environmental conditions, ensuring efficient and effective thermal control. This method is used as an optimization tool that works in conjunction with established thermal management solutions, such as GaN, SiC, and AlN materials, which provide the physical properties necessary for effective heat dissipation. This analysis covers a temperature between −100°C and 200°C, examining frequencies up to 50 GHz validating the accuracy and reliability for GaAs and GaN HEMT thermal optimization. Overall, this research achieves a minimum error of 5.97834e−01 and 6.01251e−05. Also, SA‐OSNN achieves an accuracy of 97% with better performances than existing methods.
