Review on Tooth Flank Fracture Failure of Hardened Gears

Jixie chuandong, 2022
There is a new tooth failure mode for hardened gears called tooth flank fracture(TFF). ISO published a technical specification for calculating the load capacity of tooth flank failure in 2019.

A Novel C19orf47‐AKT2 Chimeric RNA Generated by Cis‐Splicing of Adjacent Genes Is Associated With Glioblastoma Prognosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Malignant gliomas pose significant therapeutic challenges. This study aimed to identify and characterize a novel chimeric RNA in glioma and assess its clinical and functional significance for precision treatment. Methods The C19orf47‐AKT2 chimeric RNAs were identified through RNA sequencing and validated by polymerase chain reaction.

Non-autonomous approximations governed by the fractional powers of damped wave operators

Electronic Journal of Differential Equations, 2019
In this article we study non-autonomous approximations governed by the fractional powers of damped wave operators of order $\alpha \in (0,1)$ subject to Dirichlet boundary conditions in an $n$-dimensional bounded domain with smooth boundary.

Ultrasonic treatment with nickel electroplating combined with oxidation for developing γ-Al2O3 washcoat on Fe-Cr-Al substrate [PDF]

, 2012
Fe-Cr-Al is used as metallic support for catalytic converter due to its high thermal conductivity, lower heat capacity, high temperature and mechanical shock resistance. γ-Al2O3 is the most widely used material as washcoat which embedded on metallic

NOTCH2NLC Repeat Expansions in Parkinsonian Disorders: Clinical and Neuroimaging Characteristics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disorder caused by NOTCH2NLC GGC repeat expansions, with heterogeneous clinical manifestations, including parkinsonism. Recent studies have identified NOTCH2NLC repeat expansions in patients with Parkinson's disease (PD) and atypical parkinsonism (aPM), suggesting ...

Finite fractal dimensionality of attractors for nonlocal evolution equations

Electronic Journal of Differential Equations, 2013
In this work we consider the Dirichlet problem governed by a non local evolution equation. We prove the existence of exponential attractors for the flow generated by this problem, and as a consequence we obtain the finite dimensionality of the global

Dynamic Response Analysis of Tooth Root Crack Failure in Helical Idler Gear System Under Different Working Flank Conditions

Actuators
Helical idler gear transmission systems can adapt to high-speed, heavy-load working environments and are thus widely used in aerospace, shipbuilding, and other heavy industry sectors. Root crack is one of the common fault types.

STEREO and Wind observations of a fast ICME flank triggering a prolonged geomagnetic storm on 5-7 April 2010

, 2010
On 5 April 2010 an interplanetary (IP) shock was detected by the Wind spacecraft ahead of Earth, followed by a fast (average speed 650 km/s) IP coronal mass ejection (ICME).

RRP9 Promotes Esophageal Squamous Cell Carcinoma Progression through E2F1 Transcriptional Regulation of CDK1

Advanced Biology, EarlyView.
The study reveals that RRP9 is abnormally highly expressed in ESCC tissues and is closely associated with poor prognosis in patients. Furthermore, it is found that RRP9 promotes ESCC progression through enhancing the E2F1‐mediated transcriptional regulation of CDK1.

Physical properties of lava flows on the southwest flank of Tyrrhena Patera, Mars [PDF]

Tyrrhena Patera (TP) (22 degrees S, 253.5 degrees W), a large, low-relief volcano located in the ancient southern highlands of Mars, is one of four highland paterae thought to be structurally associated with the Hellas basin.
