Effect of extended tooth contact on the modeling of spur gear transmissions [PDF]

open access: yes
In some gear dynamic models, the effect of tooth flexibility is ignored when the model determines which pairs of teeth are in contact. Deflection of loaded teeth is not introduced until the equations of motion are solved.

Nutritional c‐Fos Induction Rewires Hepatic Metabolism and Can Promote Obesity‐Associated Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
It is shown that hepatic c‐Fos responds to feeding, altering de novo lipogenesis, glycolysis, and a wide range of steatosis‐associated metabolic signaling pathways. Obesogenic diets cause hepatic c‐Fos overexpression, insulin resistance, and the induction of metabolic reprogramming‐related genes.

Gear Lubrication and Cooling Experiment and Analysis [PDF]

open access: yes
A gear tooth temperature analysis was performed using a finite element method combined with a calculated heat input, a calculated oil jet impingement depth, and estimated heat transfer coefficients for the different parts of the gear tooth that are oil ...

The impact of Limosilactobacillus reuteri in combination with non-surgical periodontal therapy on periodontal clinical parameters and salivary and subgingival microbiota composition in individuals with stage III–IV periodontitis: a randomized controlled trial

open access: yesBMC Oral Health
Background The clinical and microbiological outcomes of probiotic-assisted periodontal therapy remain inconclusive in prior research. This ambiguity may stem from uncertainties regarding the duration, dosage, and administration route of probiotics ...

Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

open access: yesAdvanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.
