AbstractBACKGROUNDTea is the second most consumed beverage worldwide and its health benefits have been extensively studied because of its rich flavanol content. This study aims to evaluate the efficacy of a novel continuous step‐wise temperature extraction process in maximising antioxidant activity, total phenolic content and flavanol concentration of different tea beverages.RESULTSContinuous step‐wise temperature extraction produced the highest absolute antioxidant capacity, total phenolic content and concentration of major tea flavanols in Yuhua tea compared to the other tea types at all extraction points. Despite having the lowest baseline concentration of tea flavanols, Lapsang Souchong tea showed the greatest increase in catechin and epigallocatechin‐3‐gallate levels with the continuous step‐down temperature process, by over 500% and 300%, respectively. In addition, Moonlight White tea showed the greatest percentage change in total antioxidant capacity and phenolic content at the end of the process compared to the baseline. Furthermore, the continuous step‐wise temperature extraction showed a moderate increase in caffeine concentration in all the tea samples.CONCLUSIONOur findings revealed a beneficial impact of continuous step‐wise temperature extraction on the antioxidant capacity, phenolic content and flavanol profile in different types of tea, which may be valuable in the production of added‐value tea beverages. © 2024 Society of Chemical Industry.

Published: November 2024

AbstractMonte Carlo ray tracing can produce high‐fidelity stereo renderings of 3D scenes. However, the computational costs associated with shading indirect illumination can be prohibitively expensive. While techniques like reprojection and reconstruction have been employed to reduce the inherent redundancy in stereo rendering, they often fall short in addressing issues like remaining holes and appearing artifacts, particularly in the case of specular reflections. In this paper, we introduce a stereo rendering method that leverages both ray tracing and 3D warping, incorporating techniques for reusing indirect illumination calculations and perception‐driven reconstructions. At the pre‐rendering stage, we reuse indirect illumination calculations in the background and 3D warping regions, resulting in significant savings of indirect illumination calculations in the testing scenes. For the remaining holes, we adopt a sparse sampling strategy for representative pixels, guided by saliency maps. We iteratively reconstruct indirect illumination, employing a stopping criterion based on just noticeable difference thresholds. Through equal‐sample experiments, we showcase the efficiency achieved by the proposed method in reducing high‐level sampling costs for 87.688% ~ 99.581% regions of the test scenes. Furthermore, the proposed method excels in accurately rendering both diffuse and specular reflections, ultimately enhancing the overall visual perception quality.

AbstractNegative mental health outcomes are prevalent among veterans exposed to military‐related stressors and are associated with social isolation. Limited research exists on resilience following military separation and its impact on social isolation in veterans. We examined resilience against military‐related stressors and 2‐year longitudinal associations with social isolation indicators; gender differences were also explored. U.S. military veterans (N = 351, 70.4% men) who deployed to the wars in and around Iraq and Afghanistan following the September 11, 2001, terrorist attacks (9/11) were recruited as part of a longitudinal assessment study examining predictors of postdeployment adjustment. Using a residualization approach, resilience was approximated as low stressor reactivity (SR), calculated by regressing mental health onto military‐related stressor exposure. Military‐related stressors were significantly associated with posttraumatic stress disorder (PTSD) related to both events during post‐9/11 deployment (deployment event) and outside of post‐9/11 deployment (other event), functional disability, and depression. After correcting for multiple comparisons, only SR derived from depressive symptoms predicted more closeness difficulties in social relationships longitudinally, B = 0.50, q = .023. Women also demonstrated higher SR than men regarding other event‐related PTSD symptoms, B = −0.52, q < .001; functional disability, B = −0.28, q = .028; and depression, B = −0.34, q = .012. Results suggest that veterans with higher depressogenic reactivity to military‐related stressors were more likely to endorse discomfort with closeness than those with lower depressogenic reactivity. Women veterans may also be more impacted by nondeployment traumatic distress, psychosocial dysfunction, and depression in response to military‐related stressors.

ObjectiveTo evaluate the long‐term results of endoscopic myoneurectomy (EMN) of the thyroarytenoid (TA) muscle for the treatment of adductor spasmodic dysphonia (AdSD), with an emphasis on vocal outcomes, adverse effects, and recurrence.MethodsA total of 48 patients underwent up to three EMNs of the TA muscle and were followed for at least 18 months to evaluate the efficacy, based on patient and examiner assessments, and safety of the procedure(s). Vocal outcomes were evaluated through the use of the 30‐item Voice Handicap Index (VHI‐30) questionnaire and subjective (patient‐reported) assessment.ResultsIn this group, 38 patients (79.2%) were considered successful. The median VHI‐30 score at baseline was 97, decreasing to 26 after treatment, and the median subjective postprocedural improvement was 88.5%. The most common adverse effects were granulomas (in 18 cases), glottic insufficiency (in two), and dyspnea (in one).ConclusionsAlthough up to three procedures can be needed to achieve a high success rate, EMN of the TA muscle can provide excellent benefits in terms of vocal function with a low rate of complications.Level of Evidence4 Laryngoscope, 2024

Published: November 2024

AbstractDissolved oxygen (DO) in the bottom layer is essential for benthic organisms, and its temporal variations are widely concerned. However, previous studies have primarily focused on the long‐term variations of bottom DO, leaving its high‐frequency (HF) dynamics inadequately understood. This study addresses this gap by utilizing two seafloor monitoring systems that provide 3‐year‐long HF records in a typical temperate shelf sea, the Bohai Sea, China. During the stratified period each year, bottom DO exhibits notable HF fluctuations superimposed on its seasonal cycle. These HF signals originate from tide‐induced vertical mixing, showing peaks at various tidal frequencies. Notably, significant shallow‐water tidal signals are observed in bottom DO due to the frequency doubling of semi‐diurnal and diurnal tidal currents. Moreover, bottom DO demonstrates strongly asymmetric responses to tidal mixing on HF time scales. To be specific, the bottom DO increases with the intensity of tidal mixing, with this process being exceptionally rapid under conditions of weak tidal mixing. The underlying cause of this asymmetry is the markedly stronger vertical DO gradient near the seabed due to sediment oxygen demand. A process‐oriented biological model successfully reproduced observational features, further supporting our theoretical inference. These findings highlight the joint role of tidal mixing and sediment oxygen demand in modulating the HF dynamics of bottom DO in temperate shelf seas, underscoring their significance for the refined prediction of bottom DO in the future.

AbstractAquatic organisms are natural data loggers and record chemical variations within hardened accretionary structures like shells and teeth. Chemical sclerochronology is the study of these chemical variations through time and how they are used to understand environmental change and the physiology and ecology of species. While sclerochronology research has largely focused on bivalves, teleost fish, and hard corals, there are many other aquatic taxa rich with time‐resolved chemical data. To expand focus to these “other” taxa and determine the state‐of‐play, we compiled a database of chemical sclerochronology studies spanning nine living phyla and 19 classes. We then examined research trends and knowledge gaps across these taxa and showcase their exciting potential to collect critical data and address pressing environmental and ecological challenges. We hope this synthesis will encourage further research on species across the tree of life, as well as foster collaboration among the established and lesser‐known fields of sclerochronology.

Published: November 2024

AbstractOn‐chip wavefront manipulation of terahertz surface plasmons is crucial for the miniaturization and practical application of terahertz technology. Recently, topological metasurfaces have emerged as a promising avenue for spin‐decoupled wavefront manipulation, leveraging the unique topological properties of non‐Hermitian matrices near their singular points. Despite their innovative phase control mechanisms, topological metasurfaces have not yet been explored for surface plasmon devices. Here, spin‐decoupled wavefront manipulation of terahertz surface plasmons is experimentally achieved using freestanding topological metasurfaces. This approach promises to expand the control methods of surface plasmons and broaden the application scenarios of topological metasurfaces, providing a new paradigm for the design of integrated on‐chip terahertz devices.

AbstractThe emergence of “precision medicine” marks a notable shift in cancer treatment, moving from a tumor type–oriented approach to a more targeted, gene‐oriented approach. Detecting low‐abundance mutant genes in blood is challenging but crucial for personalized treatment plans. Herein, a novel platform combining catalytic hairpin self‐assembly (CHA)‐mediated self‐calibrating surface‐enhanced Raman spectroscopy (SERS) with a high‐throughput Raman system (CCSPS) was designed. This platform enables ultrasensitive and rapid genotype analysis of gene mutations. The development of CCSPS specifically targets EGFR mutations, which serve as crucial therapeutic targets for precision therapy in lung cancer. This system shows excellent sensitivity and selectivity, capable of detecting multiple EGFR mutations (Del‐19, L858R, and T790M) with a detection limit as low as attomolar levels. Additionally, precise genotyping analysis was successfully conducted on 42 clinical samples using the CCSPS, yielding results consistent with those obtained through next‐generation sequencing. These results underscore the efficacy of the CCSPS in noninvasively identifying circulating tumor DNA (ctDNA) mutations, facilitating immediate therapeutic decision making at the bedside. In summary, the CCSPS is a fast, accurate, versatile, and compact testing system capable of precisely screening individuals who stand to benefit from targeted therapy, thus promoting personalized and precise healthcare.

Published: November 2024

AbstractFluorescence thermometry has garnered significant attention for its noninvasive, remote, highly sensitive, and rapid temperature measurement capabilities. However, achieving superior sensitivity at high temperatures remains a persistent challenge. Herein, a series of Rb2−xCsxHfCl6: y%Te4+ perovskites are synthesized to investigate the impact exerted by A‐site regulating regarding the luminescence efficiency and temperature‐responsive capabilities. Te4+ doping significantly enhances luminescence intensity, with the broadband yellow light resulting from electron–phonon coupling within the soft lattice, driven by self‐trapped exciton emission. Furthermore, A‐site regulation demonstrates that increasing Cs⁺ content induces enhanced Jahn–Teller distortion, thereby boosting luminescence efficiency. However, the pure Rb sample exhibits the lowest thermal activation energy, as the temperature rises, increased phonon‐exciton coupling and the defect activity accelerate the nonradiative recombination, drastically decreasing fluorescence lifetime by two orders of magnitude from 300 to 390 K. Utilizing this exceptional thermal sensitivity, a lifetime‐based fluorescence thermometer is developed, attaining a breakthrough relative sensitivity reaching 20.69% K−1 at 390 K, with high repeatability across multiple heating and cooling cycles. Additionally, a high‐temperature warning system for lubricating oil pipelines is designed, demonstrating robust monitoring capabilities. This work offers a new perspective on developing highly sensitive thermometers that utilize halide perovskites for high‐temperature applications.

Published: November 2024

AbstractTechnologies that facilitate recycling are attracting considerable interest from the perspective of resource constraints. In the present study, degradable primer films are to facilitate the removal of strongly bonded joints. This film consists of a light‐cured trifunctional anthracene compound that thermally decomposes to its original liquid state. To demonstrate its function as a degradable primer film and verify its range of applications, various substrates, such as aluminum alloys, stainless steel, carbon fiber‐reinforced plastics, carbon fiber‐reinforced thermoplastics, and polyetheretherketone, are bonded through the primer film using a two‐component epoxy adhesive. All the single‐lap specimens exhibit strengths above 10 MPa, which is sufficient, or base material fracture. When adhesive bonding specimens prepared using the same procedure are heated at 180 °C to transform the coating film to a liquid state, the bond strength is significantly reduced. The primer film is expected to exhibit long‐term stability of more than one year at ≈60 °C.

Smart Crowding on pH‐Induced Elasticity of Weakly Anionic poly(N‐Isopropylacrylamide)‐Based Semi‐Interpenetrating Polymer Networks via Integration of Methacrylic Acid and Linear Polyacrylamide Chains
Authors: Kalkan Birgul , Orakdogen Nermin 
Published: November 2024

AbstractWeakly anionic semi‐interpenetrating polymer networks (semi‐IPNs), comprised of copolymer poly(N‐isopropylacrylamide‐co‐methacrylic acid) P(NIPA‐MA) and linear poly(acrylamide) (LPA) chains as macromolecular crowding agent, are designed to evaluate pH‐induced swelling and elasticity. Uniaxial compression testing after swelling in various pH‐conditions is used to analyze the compressive elasticity as a function of swelling pH and LPA‐content. The swelling of P(NIPA‐MA)/LPA semi‐IPNs is strongly pH‐dependent due to MA units incorporated into the copolymer network which already exhibits temperature‐sensitivity by presence of PNIPA counterpart. Since the behavior of semi‐IPNs is a combination of PMA, LPA, and PNIPA moieties, the sensitivity of swelling to external pH can be modified with increasing swelling temperature. At high pH conditions, LPA‐doped semi‐IPNs show elasticity representing soft and loosely cross‐linked structure. Elastic modulus is higher in acidic pH condition due to the less swelling tendency, while in basic pH, the modulus decreases significantly in coordination with swelling. Oscillatory swelling reveals how fast semi‐IPNs can respond to environmental pH change (2.1–10.7). By describing adsorption potential of semi‐IPNs for cationic methylene blue uptake by pseudo‐first‐order and Freundlich model, the designed poly(NIPA‐MA)/LPA semi‐IPNs emerge as promising smart materials in applications requiring rapid response to changes in temperature and pH via diffusional properties.

Published: November 2024

AbstractBackgroundPersons with Parkinson's disease (PD) experience progressive motor and non‐motor symptoms which may influence their ability to drive a car. This is experienced as a massive challenge by many affected individuals, for whom being able to drive a car is vital to maintain functional independence.ObjectivesWe assessed how the diagnosis of PD affected the possession of a driving license, how people with PD had adapted their driving style, and to what extent they had communicated about their driving ability with their healthcare professionals. We also evaluated their knowledge on insurance‐ and Driver and Vehicle Licensing Agency (DVLA)‐related implications.MethodA cross‐sectional 10‐item survey was completed by 540 participants of a population‐based cohort of persons with PD in the Netherlands (PRIME‐NL study).ResultsParticipants had a mean age of 70 years and disease duration of 7.3 years. 84% possessed a valid driving license. Of those who gave up their license, this was done mostly (78%) on a voluntarily basis. Forty percent of those with a driving license adjusted their driving style. Over 50% of respondents had not discussed the impact of PD on their driving ability with their healthcare professionals. Although not compulsory by Dutch law, 52% of the respondents had informed the DVLA about their diagnosis.ConclusionThis study highlights the need for information and support from healthcare professionals to proactively address driving in their clinical practice. This will help persons with PD in their efforts to maintain their driving license for as long as possible.

AbstractTask Group (TG) 314 of the American Association of Physicists in Medicine (AAPM) was charged to develop guidance for recovering from fault states in radiation therapy, specifically regarding the delivery of photon or electron beams using a linear accelerator (linac) including ancillary systems. The fault conditions addressed may involve software, hardware, or a combination of causes. The report provides detailed recommendations for the proactive steps to be taken before a fault, the actions to be taken at the time of a fault, and the safety steps before returning a linac to clinical service, as well as the activities that device manufacturers and standard organizations can do to prevent and resolve the faults. A user‐maintained log of prior faults; establishment of remote access by the vendor; and user training in emergency gantry, couch, and door motions are all useful proactive steps. At the moment of downtime and after ensuring the safety of the patient, the report stresses the importance of capturing fault information, prompt contact with the service engineer after the initial assessment, and considerations for communicating the estimated duration before the linac is returned to service. The medical physicist has a critical responsibility to assess the impact of the fault on patient care. Before resuming clinical use, the medical physicist must both determine the level of testing required to ensure safe operation of the linac and ensure any partially or totally delivered treatments have been correctly saved for accurate completion of the treatment fraction. The report stresses the roles of the radiation therapist, medical physicist, and service engineer to efficiently and safely address linac downtime. The appendices contain a description of the efforts of several organizations regarding linac safety: Integrating the Healthcare Enterprise—Radiation Oncology, International Standards Organization/International Electrotechnical Commission, Radiation Oncology Safety Stakeholder Initiative, and the AAPM Vendor Relations and Product Usability Subcommittee.Disclaimer: The recommendations of this TG should not be used to establish regulations. These recommendations are guidelines for Qualified Medical Physicists and others to use and appropriately interpret for their institution and clinical setting. Each institution may have site‐specific or state‐mandated needs and requirements which may modify their usage of these recommendations.
