“Smelltronics”—From Gas to Smell Sensing

This review discusses recent trends in smell and odor-sensing studies, including materials, devices, and interfaces. Since the invention of chemical sensors, particularly over the past few decades, gas sensor materials and devices for small molecules have been extensively investi...

Nuclear Pan‐Lysine Lactylation Immunoreactivity Is Associated With Poor Prognosis in Intrahepatic Cholangiocarcinoma

AIM: Lysine lactylation (Kla) links cellular metabolism to gene regulation, but its significance in intrahepatic cholangiocarcinoma (ICC) remains unclear. METHODS: Nuclear pan-Kla immunoreactivity was evaluated in 118 patients who underwent curative-intent resection for ICC. Asso...

Long‐Term Restoration of Anticoagulant Function After Liver Transplantation for Severe Congenital Protein C Deficiency: A Single‐Center Experience Involving Three Pediatric Patients

Severe congenital protein C (PC) deficiency is a rare inherited coagulation disorder that can be difficult to control with conventional medical treatment alone. We report a single-center case series of three pediatric patients with severe congenital PC deficiency who underwent li...

Parafermionizing the monster

A bstract We study the parafermionization of the Monster CFT with respect to its ℤ pA subgroups, with p an odd prime. Under certain assumptions, we show that the parafermionization is equal to a non-invertible gauging of $$ \mathcal{P}(p)\times \mathcal{P}{(p)}^{\vee } $$ P p × P...

Direct speciation of ultra-trace platinum in marine ferromanganese oxides by wavelength-dispersive XAFS

Abstract Ultra-trace platinum (Pt) in marine ferromanganese oxides (FMOs) has remained inaccessible to direct XAFS analysis because of its extremely low abundance and severe interferences from co-existing elements. We achieved the first direct speciation of Pt at the 1 μg g−1 lev...

The Temporal Resolution Needed for Speech Intelligibility Assessed with Mosaic Speech: Effects of Block Duration, Age, and Word Familiarity

Background/Objectives: Mosaic speech was used to further investigate the auditory system’s temporal resolution needed for speech intelligibility. Mosaic speech is a form of degraded speech segmented in frequency × time blocks with no discernible temporal fine structure and with d...

Antiferromagnetic order and crystalline electric field in noncentrosymmetric hexagonal R E Ru 6 As 4 ( R E = Sm and Yb )

We investigated the electronic properties of $RE{\mathrm{Ru}}_{6}{\mathrm{As}}_{4}(RE=\mathrm{La}, \mathrm{Ce}, \mathrm{Sm}, \text{and} \mathrm{Yb})$ using single-crystalline samples grown by the Bi-flux method. These compounds crystallize in the noncentrosymmetric hexagonal ${\m...

Complete strategy spaces reveal hidden pathways to cooperation

Understanding how cooperation emerges and persists is a central challenge in evolutionary game theory. However, models of communication often rely on restricted strategy sets, making it unclear whether omitted behaviours alter cooperation. Here, we study the complete deterministi...

Epithelial integration in tissue-engineered oral mucosa using RGDTFI-presenting micropatterned collagen scaffolds

Objective To determine whether presentation of the integrin αvβ3/αvβ5-binding peptide motif RGDTFI on micropatterned collagen scaffolds improves epithelial coverage and stabilizes the epithelial–scaffold interface during fabrication of tissue-engineered oral mucosa (TEOM). Method...

Generalizing molecular design via flexible search space control

Abstract Recent advances in generative artificial intelligence have made in silico molecular design a powerful approach for exploring chemical space toward specific goals. However, despite the need for trial-and-error adjustment of generative strategies and reward formulations, m...

Zealots lower coordination barriers but undermine cooperation in multiplayer games

Abstract How can a small group of committed cooperators shape collective outcomes in social dilemmas? Previous studies have shown that zealots—individuals who always cooperate—can promote cooperation in prisoner's dilemmas. Yet real-world cooperation also involves multiplayer coo...

Mathematical modeling for a primitive form of habituation in an amoeba

Abstract Learning abilities, once thought to be unique to higher animals, have been reported to exist in their primitive form in single-celled organisms. This has triggered a growing interest in carefully examining the nature and mechanisms of the primitive versions of learning a...

Global Cowling Effects in the Sq‐EEJ Current System Under Electrostatic Approximation: Theoretical Simulation

Abstract The solar quiet (Sq) current and equatorial electrojet are widely known as one of the fundamental currents in ionosphere. Although the Sq‐EEJ current system has been extensively investigated, the manner in which Hall and Pedersen current components collectively organize...

A Programmable Nanovesicle Platform for MegapascalPressure Sensing

Abstract Hydrostatic pressure (HP) is a subtle yet pervasive force that shapes chemistry and biology from the ocean floor to living cells─yet real-time HP sensing at the microscale remains elusive. Here, we report pyrene-modified polyionic complex vesicles (Pyr-PICsomes) as a cla...

The Clinicopathological Characteristics and Prognosis of Cholangiolocarcinoma: A Multicenter Study With a Central Pathology Review

BACKGROUND: Cholangiolocarcinoma (CLC) is a rare liver cancer with ≥ 80% ductular configuration (DC). Given its rarity, its clinicopathological characteristics remain poorly understood, and its status as a distinct disease entity remains controversial. We conducted a nationwide m...

The minimal supersymmetric standard model with non-invertible selection rules

Abstract We investigate a framework of the minimal supersymmetric standard model (MSSM) in which the quark and lepton flavor structure and suppression of flavor-changing neutral currents (FCNCs) are governed by non-invertible selection rules. By implementing such non-group-like f...

Do sectarian differences affect support for armed non-state actors? Evidence from survey experiments in Lebanon, Iraq, and Yemen

Abstract Sectarian cleavages are widely seen as central to Middle Eastern conflict, and Iran-backed armed non-state actors (ANSAs)—Hezbollah, the popular mobilization units, and the Houthis—are often portrayed as sectarian militias. Yet there is little empirical evidence that pub...

Peripheral Functionalization of Antiaromatic 5,15-Dioxaporphyrin for the Synthesis of Oligomers

Abstract Partial peripheral functionalization of the antiaromatic nickel(II) 5,15-dioxaporphyrin (NiDOP) was explored to create substituted products suitable as substrates for oligomer synthesis. Syn- and anti-type diaryl-substituted NiDOPs were synthesized from tribromo-substitu...

Turbidity currents after the 2024 Noto Peninsula Earthquake and their environmental impacts on the Toyama Deep-Sea Channel in the Japan Sea

Abstract The deep-sea environment before and after the 2024 Noto Peninsula Earthquake was investigated using a series of hydrographic and mooring observations in the Toyama Deep-Sea Channel (TDSC), Toyama Bay. Transient oxygen depletion was observed after the earthquake, and low-...

Role of interfacial contact topology in reduction-dependent molten iron–slag dripping through coke-packed beds

Hydrogen-enriched blast furnace operations change the reduction state and composition of dripping slag; however, its effects on coupled iron–slag flow through coke-packed beds remain insufficiently quantified. Therefore, dynamic multiphase simulations were performed for molten ir...
