Ultrahigh-voltage potassium-ion batteries (PIBs) with cost competitiveness represent a viable route towards high energy battery systems. Nevertheless, rapid capacity decay with poor Coulombic efficiencies remains intractable, mainly attributed to interfacial instability from aggressive potassium metal anodes and cathodes. Additionally, high reactivity of K metal and flammable electrolytes pose severe safety hazards.

Total leaf area per shoot () can reflect the photosynthetic capacity of a shoot. A prior study hypothesized that is proportional to the product of the sum of the individual leaf widths per shoot () and the maximum individual leaf length per shoot (), referred to as the Montgomery-Koyama-Smith equation (MKSE). However, empirical evidence does not support such a proportional relationship hypothesis, as was found to allometrically scale with , i.

1-Methylnaphthalene is a critical component for constructing fuel surrogates of diesel and aviation kerosene. However, the reaction pathways of 1-methylnaphthalene included in existing detailed chemical kinetic models vary from each other, leading to discrepancies in the simulation of ignition and oxidation processes. In the present study, reaction classes and pathways involved in the combustion of 1-methylnaphthalene were analyzed, and effects of rate constants of reactions related to 1-methylnaphthalene and its significant intermediates on ignition delay times and species concentration profiles were discussed, involving hydrogen abstraction and substitution reactions of 1-methylnaphthalene, oxidation, isomerization, and addition reactions of 1-naphthylmethyl, hydrogen abstraction and oxidation reactions of indene, as well as the oxidation of indenyl and naphthalene.

Pathogenesis-related proteins (PR), whose expressions are induced by biotic and abiotic stress, play important roles in plant defense. Previous research identified the salt-induced HcPR10 gene in the halophyte Halostachys caspica as a regulator of plant growth and development through interactions with cytokinin. However, the mechanisms by which HcPR10 mediates resistance to abiotic stress remain poorly understood.

Reproductive factors are well-established risk factors for breast cancer. The prevailing hypothesis suggested that stem cell changes may be the key underlying mechanisms, but epidemiological evidence has been notably scarce. Herein we examined the relationship between reproductive risk factors and the expression of well-established stem cell markers CD44, CD24, and ALDH1A1 in benign breast biopsy non-cancerous samples.

Article Synopsis
  • Signal amplification techniques using catalytic silver deposition on immunogold labels have been improved for immunoassays, but traditional devices are often too big, expensive, and complicated for point-of-care testing.
  • Researchers have developed a new, portable 3D-printed device that combines capillary liquid electrode glow discharge (CLEGD) and optical emission spectrometry (OES) for detecting carcinoembryonic antigen (CEA) in small samples effectively.
  • This innovative system can detect Ag(I) as low as 0.9 ng/mL and shows similar detection capabilities to more complex systems, covering a linear range of 1-500 ng/mL for CEA quantification.

  • Parkinson's disease (PD) is a progressive movement disorder becoming more common due to an aging population, and researchers aimed to explore rare genetic variants that could help explain its development.
  • Whole-exome sequencing was conducted on a large group of PD cases and controls of Asian ancestry, revealing significant links between the genes GBA1 and SMPD1 and the risk of developing PD, confirmed in additional samples.
  • The research found that specific SMPD1 variants that reduced enzyme activity were particularly associated with PD risk, with a prominent Asian-specific variant being common among carriers.

  • SMT-like esophageal squamous cell carcinoma (ESCC) is a rare form of esophageal cancer that can be easily misdiagnosed due to its endoscopic appearance resembling benign subepithelial lesions and often negative biopsy results.
  • A study involving six patients analyzed clinicopathological data and performed endoscopic ultrasound (EUS) and immunohistochemical tests on tumor tissues to identify specific markers associated with this cancer.
  • Results showed that EUS revealed distinct nonuniform lesions indicating cancer, with EUS-guided fine needle aspiration (EUS-FNA) confirming the diagnosis; the tumors exhibited a specific immune marker profile that suggests they might originate from submucosal glands.

Background: Hydroxy fatty acids represent an emerging class of compounds with promising applications in the chemical, medicinal and functional food sectors. The challenges associated with their chemical synthesis have spurred exploration of biological synthesis as an alternative route, particularly through the use of fatty acid hydratases. Fatty acid hydratases catalyse the regioselective addition of a hydrogen atom and a hydroxyl group from a water molecule to the carbon-carbon cis-double bond of unsaturated fatty acids to form hydroxy fatty acids.

Tumor-associated neutrophils (TANs) play a crucial role in tumor progression and exhibit prolonged survival. However, the mechanism underlying their extended lifespan and significance in laryngeal squamous cell carcinoma (LSCC) remains unclear. Herein, it is observed that apoptosis of TANs is significantly delayed owing to induction by tumor-derived G-CSF and GM-CSF through the activation of the PI3K-AKT signaling pathway, upregulation of anti-apoptotic Mcl-1 expression, and downregulation of activated Caspase-3 levels.

Directly solving sophisticated partial differential equation constrained optimization problems is not only extremely time-consuming, but also very hard to find unique optimal solutions. Here, we propose stable and efficient surrogate models for seawater reverse osmosis desalination processes that enable thorough quantitative description of hydrodynamics and local transport characteristics in narrow flow channels. Without iteratively solving complex multi-physics simulation problem taking several hours, the proposed multi-scale design optimization framework significantly reduces the problem complexity by computing the surrogate models in seconds.

  • Scientists used special data from a detector to look for rare particle decays of a type called the D_{s}^{+} decay, focusing on how it might change into other particles like kaons or pions.
  • They found strong evidence for the decay D_{s}^{+}→π^{+}ϕ and also discovered a new decay D_{s}^{+}→ρ^{+}ϕ, both involving particles that decay into pairs of electrons.
  • However, they didn't find strong signals for three other types of decays they were looking for, and set limits on how often those changes could happen.
