MetaDetection: wireless intelligent detection of multiliquids by using space-time-coding metasurface.

The increasing demand for public safety has created an urgent need for high-performance technologies capable of detecting hazardous liquids with high accuracy, efficiency, and cost-effectiveness. Conventional liquid detection methods often fall short in addressing these requirements due to limitations in precision, operational complexity, and scalability. This study introduces a wireless intelligent system for the detection of suspicious liquids, leveraging advancements in programmable metasurface and software defined radio technologies.

Evaluation of [F]F-PTTP as a Positron Emission Tomography Radioligand for Imaging P2X7 Receptors in Epileptic Rats.

Patients with epilepsy often face significant challenges, with one-third of them being resistant to available antiseizure medications, leading to drug-resistant epilepsy (DRE). The P2X7 receptor (P2X7R), a mechanistic and inflammatory biomarker, exhibits increased expression during epileptogenesis. P2X7R antagonists effectively reduce the severity of seizure and neuronal death, highlighting this receptor as a potential therapeutic target.

Comprehensive evaluation of plasma tau biomarkers for detecting and monitoring Alzheimer's disease in a multicenter and multiethnic aging population.

Over 20% of patients with Alzheimer's disease (AD) worldwide are Chinese, although the efficacy of existing blood-based measures of AD biomarkers is largely unknown in Asian cohorts. Here we explored how plasma tau biomarkers correlated with cross-sectional and longitudinal AD-related outcomes and their diagnostic performance in 1,085 participants from three independent studies, including two Chinese cohorts, Greater-Bay-Area Healthy Aging Brain Study (n = 425) and Huashan (n = 297), and the North American Alzheimer's Disease Neuroimaging Initiative cohort (n = 363). Plasma p-tau217 performed best in classifying Aβ-positron emission tomography (PET) and tau-PET positivity throughout the AD continuum and correlated with all AD-related outcomes.

Chitosan/PEG nanoparticle-embedded oleogels improve blueberry derived resveratrol bioavailability and antioxidant capacity.

Blueberry polyphenols exhibit antioxidant and anti-inflammatory properties with a plausible role in preventing chronic diseases. However, applications in food or supplements is limited by low bioavailability.

Presynaptic loss and axonal degeneration synergistically correlate with longitudinal neurodegeneration and cognitive decline.

Introduction: Baseline and longitudinal characteristics of cerebrospinal fluid (CSF) growth-associated protein 43 (GAP-43) and plasma neurofilament light (NfL) and how they correlate interactively with neurodegeneration and cognitive decline in Alzheimer's disease (AD) are not fully understood.

Methods: We investigated dynamic changes of CSF GAP-43 and plasma NfL across different AD stages and their association with longitudinal neurodegeneration and cognitive decline up to 12 years.

Results: Individuals with hippocampal atrophy, AD-signature cortical thinning, or hypometabolism (N+) had faster plasma NfL increase rates than healthy individuals, regardless of amyloid/tau status.

A New [PMoO]-Based Ni Compound: Electrochemical and Photocatalytic Properties for Water Pollutant Removal.

A polyoxometalate-based metal-organic complex with the ability to treat pollutants in water was obtained under hydrothermal conditions, namely [Ni(HL)(HL)](PMoO)·3HO·4HO () (HL = 4,4'-(1H,1'H-[2,2'-biimidazole]-1,1'-diyl)dibenzoicacid). Structural analysis reveals that the [Ni(HL)(HL)] units are interconnected into a 2D layer via hydrogen bonds between adjacent carboxyl groups and water molecules of crystallization. [PMoO] anions are embedded within the larger pores of the layer and are connected to the adjacent layers through hydrogen bonds, ultimately expanding the structure into a 3D supramolecular architecture.

White matter fractional anisotropy decreases precede hyperintensities in Alzheimer's disease.

The associations of β-amyloid (Aβ) and tau deposition with white matter (WM) degeneration in Alzheimer's disease (AD) remain inadequately elucidated. We investigate baseline and longitudinal changes of microstructural fractional anisotropy (FA) and macrostructural white matter hyperintensities (WMHs) and their relationships with Aβ and tau positron emission tomography (PET) and vascular risk factors in different Aβ/tau stages defined by PET imaging. Lower levels and faster decline rates of FA occur in the AD continuum, particularly in tau-positive individuals.

Comparison of Drying Techniques to Produce Stable and Bioavailable Encapsulated ACE-2 Nanoparticles.

COVID-19 infection continues globally, with frequent emergence of unfamiliar SARS-CoV-2 variants acting to impair immunity. The competitive binding of SARS-CoV-2 spike proteins and angiotensin-converting enzyme 2 (ACE-2) can decrease the binding of the virus on native ACE-2 receptors on healthy human cells. It remains a practical approach to lessen viral spread.

Results: Plasma NT1-tau significantly increased in symptomatic AD and displayed positive associations with Aβ PET (positron emission tomography) and tau PET.

Selective Plasma Treatment Endowing Low-Friction and Wear-Resistant Surface of Polycrystalline Diamond against Copper.

Despite its unrivaled hardness, polycrystalline diamond can be severely worn under the interaction with softer copper during the ultrafine copper wire drawing process. The influence of the polycrystalline diamond surface state on its friction behavior is investigated in this work, and argon, oxygen, and hydrogen plasma treatments are adopted to regulate the surface state of diamond. When sliding against copper, the original diamond plate exhibits a coefficient of friction (COF) exceeding 0.

Frameless Graph Knowledge Distillation.

Knowledge distillation (KD) has shown great potential for transferring knowledge from a complex teacher model to a simple student model in which the heavy learning task can be accomplished efficiently and without losing too much prediction accuracy. Recently, many attempts have been made by applying the KD mechanism to graph representation learning models such as graph neural networks (GNNs) to accelerate the model's inference speed via student models. However, many existing KD-based GNNs utilize multilayer perceptron (MLP) as a universal approximator in the student model to imitate the teacher model's process without considering the graph knowledge from the teacher model.

Astrocyte reactivity is associated with tau tangle load and cortical thinning in Alzheimer's disease.

Background: It is not fully established whether plasma β-amyloid(Aβ)/Aβ and phosphorylated Tau (p-Tau) can effectively detect Alzheimer's disease (AD) pathophysiology in older Chinese adults and how these biomarkers correlate with astrocyte reactivity, Aβ plaque deposition, tau tangle aggregation, and neurodegeneration.

Methods: We recruited 470 older adults and analyzed plasma Aβ/Aβ, p-Tau, glial fibrillary acidic protein (GFAP), and neurofilament light (NfL) using the Simoa platform. Among them, 301, 195, and 70 underwent magnetic resonance imaging, Aβ and tau positron emission tomography imaging.

Submerged fermentation of lentil protein isolate and its impact on protein functionality, nutrition, and volatile profiles.

Fermentation of pulses as a clean processing technique has been reported to have a favorable impact on the functional and nutritional quality of the starting materials. Compared to commonly fermented pulses such as peas and chickpeas, limited information is available on the effect of fermentation on lentils, especially when using a high protein isolate (>80% protein) as compared to seeds or flours. Therefore, in the present work, lentil protein isolate was used as a feedstock for submerged fermentation with Aspergillus niger, Aspergillus oryzae, or Lactobacillus plantarum.

Associations of Aβ deposition, cortical thickness, glucose metabolism, and microglial activation were also investigated.

The arrival time and energy of FRBs traverse the time-energy bivariate space like a Brownian motion.

The origin of fast radio bursts (FRBs), the brightest cosmic explosion in radio bands, remains unknown. We introduce here a novel method for a comprehensive analysis of active FRBs' behaviors in the time-energy domain. Using "Pincus Index" and "Maximum Lyapunov Exponent", we were able to quantify the randomness and chaoticity, respectively, of the bursting events and put FRBs in the context of common transient physical phenomena, such as pulsar, earthquakes, and solar flares.
