Interpret Gaussian Process Models by Using Integrated Gradients.

Gaussian process regression (GPR) is a nonparametric probabilistic model capable of computing not only the predicted mean but also the predicted standard deviation, which represents the confidence level of predictions. It offers great flexibility as it can be non-linearized by designing the kernel function, made robust against outliers by altering the likelihood function, and extended to classification models. Recently, models combining deep learning with GPR, such as Deep Kernel Learning GPR, have been proposed and reported to achieve higher accuracy than GPR.

Improving the mechanical properties of chitosan through blending with poly(trimethylene carbonate) copolymer.

In this study, a novel flexible material was fabricated by blending chitosan (CS) with a poly(trimethylene carbonate) (PTMC) copolymer. N-methyl-D-glucamine, which acts as a polyol, was grafted onto the PTMC copolymer to produce poly(TMC-co-TMC-glucamine) (PTTG), to enhance the hydrogen bonding interactions. The CS/PTTG blend films were then fabricated using solvent casting.

A hybrid in silico/in-cell controller that handles process-model mismatches using intracellular biosensing.

The discrepancy between model predictions and actual processes, known as process-model mismatch (PMM), remains a substantial challenge in bioprocess optimization. We previously introduced a hybrid in silico/in-cell controller (HISICC) that combines model-based optimization with cell-based feedback to address this problem. Here, we extended this approach to regulate a key enzyme level using intracellular biosensing.

Development of luciferase-based highly sensitive reporters that detect ER-associated protein biogenesis abnormalities.

Localization to the endoplasmic reticulum (ER) and subsequent disulfide bond formation are crucial processes governing the biogenesis of secretory pathway proteins in eukaryotes. Hence, comprehending the mechanisms underlying these processes is important. Here, we have engineered firefly luciferase (FLuc) as a tool to detect deficiencies in these processes within mammalian cells.

Defense-related callose synthase PMR4 promotes root hair callose deposition and adaptation to phosphate deficiency in Arabidopsis thaliana.

Plants acquire phosphorus (P) primarily as inorganic phosphate (Pi) from the soil. Under Pi deficiency, plants induce an array of physiological and morphological responses, termed phosphate starvation response (PSR), thereby increasing Pi acquisition and use efficiency. However, the mechanisms by which plants adapt to Pi deficiency remain to be elucidated.

Magnetic Circular Dichroism of Luminescent Triarylmethyl Radicals.

Stable triarylmethyl radicals are the most common carbon radical building blocks and have recently attracted much attention for their luminescent properties. However, magnetic circular dichroism (MCD) discovered by Michael Faraday and magnetic circularly polarized luminescence (MCPL) have not been observed for simple triarylmethyl radicals, probably due to their photodegradability. Here we report the first observation of MCD and MCPL of triarylmethyl radicals in solution using racemic mixtures of (3,5-dichloro-4-pyridyl)bis(2,4,6-trichlorophenyl)methyl radical (PyBTM) and (3,5-difluoro-4-pyridyl)bis(2,4,6-trichlorophenyl)methyl radical (FPyBTM), which are much more photostable than simple triphenylmethyl radical derivatives.

Occurrences of allergenicity to banana pathogenesis-related-10 (PR10) protein variants.

Pathogenesis-related-10 (PR10) proteins play significant roles in plant defence against biotic and abiotic stresses. Recently, two banana PR10 proteins (MaPR10-BeB5 and MaPR10-GNA5) were characterised and shown to exhibit antifungal properties against . In rice, transgenic overexpression of PR10 proteins conferred resistance to pathogen infection and drought tolerance without affecting productivity, highlighting their potential for agricultural applications.

Micro/Nano Hierarchical Dumbbell-like and Micropapillae Structure Improves Light Absorption and Facilitates Anti-icing/Deicing Performance.

The emergence of ice formation and accretion presents significant challenges, catalyzing an urgent need for clean and efficient anti-icing solutions. Solar energy, a powerful and sustainable resource, can be integrated with the micronano-structured superhydrophobic surface to enhance anti-icing and deicing performance through the solar photothermal effect, overcoming the limitations of a traditional superhydrophobic surface. Herein, inspired by bamboo and lotus leaves, a synergetic photothermal anti-icing superhydrophobic surface (PASS) has been developed.

Helical-Sense Matching Facilitates Supramolecular Copolymerization of Helical-Chiral Pillar[5]arenes.

Supramolecular polymerization using two-dimensional π-conjugated chiral monomers has been mainly demonstrated because the supramolecular polymerization can be controlled by stereocommunication through π-π stacking between the two-dimensional chiral monomers. We herein report supramolecular copolymerization utilizing three-dimensional pentahedrons with twisted helical chirality through different combinations of helical-chiral acidic and basic pillar[5]arenes as comonomers. In this case, helical-sense matching is key to facilitating the supramolecular copolymerization.

Post-marketing surveillance of anticancer drugs using natural language processing of electronic medical records.

This study demonstrates that adverse events (AEs) extracted using natural language processing (NLP) from clinical texts reflect the known frequencies of AEs associated with anticancer drugs. Using data from 44,502 cancer patients at a single hospital, we identified cases prescribed anticancer drugs (platinum, PLT; taxane, TAX; pyrimidine, PYA) and compared them to non-treatment (NTx) group using propensity score matching. Over 365 days, AEs (peripheral neuropathy, PN; oral mucositis, OM; taste abnormality, TA; appetite loss, AL) were extracted from clinical text using an NLP tool.

Comparative Validation of Scintillator Materials for X-Ray-Mediated Neuronal Control in the Deep Brain.

When exposed to X-rays, scintillators emit visible luminescence. X-ray-mediated optogenetics employs scintillators for remotely activating light-sensitive proteins in biological tissue through X-ray irradiation. This approach offers advantages over traditional optogenetics, allowing for deeper tissue penetration and wireless control.

Functional analysis of a S-adenosylmethionine-insensitive methylenetetrahydrofolate reductase identified in methionine-accumulating yeast mutants.

Essential amino acids (EAAs) are important for the maintenance of brain functions. Therefore, the yeast Saccharomyces cerevisiae that accumulates EAAs would help elderly people ingest appropriate levels of EAAs, which in turn could slow neurodegeneration, extend the healthy lifespan, and improve quality of life. Here, we isolated 2 mutant strains, ETH-80 and ETH-129, that accumulate the EAA methionine.

Artificial intelligence-based analysis of lower limb muscle mass and fatty degeneration in patients with knee osteoarthritis and its correlation with Knee Society Score.

Purpose: Lower-limb muscle mass reduction and fatty degeneration develop in patients with knee osteoarthritis (KOA) and could affect their symptoms, satisfaction, expectation and functional activities. The Knee Society Scoring System (KSS) includes patient reported outcome measures, which is widely used to evaluate the status of knee function of KOA. This study aimed to clarify how muscle mass and fatty degeneration of the lower limb correlate with the KSS in patients with KOA.

Weak Base-Promoted Direct Cross-Coupling of Naphthalene-1,8-diaminato-substituted Arylboron Compounds.

The indispensability of a base in Suzuki-Miyaura coupling (SMC) employing organoboronic acids/esters is well recognized, which occasionally induces competitive protodeborylation in organoboron reagents. This phenomenon is particularly pronounced in fluorine-substituted aryl and heteroaryl boron compounds. Here, we show that direct SMC of naphthalene-1,8-diaminato (dan)-substituted aryl boron compounds, Ar-B(dan), characterized by its remarkable stability toward protodeborylation due to their diminished boron-Lewis acidity, occurs utilizing a weak base in conjunction with a palladium/copper cooperative catalyst system.

A Three-Dimensional Surface-Adaptive Stretchable Sensor for Online Monitoring of Composite Materials Curing.

Recently, rigid sensors have been commonly applied to online monitoring of the core curing processes of composite materials to prevent both overcuring and under-curing. However, conventional rigid sensors are prone to causing cracks and bubbles in composite materials during the curing process, thereby affecting both the mechanical performance and the overall reliability of the materials. Herein, stretchable interdigital dielectric sensors with flexible substrates and electrodes are designed to conform to complex 3D surfaces, thus enabling embedded nondestructive monitoring of composite curing processes.
