Identification method for unsteady friction of tool flank for high efficiency milling cutter
Under the cutting loads of high efficiency and intermittent, the friction status between the tool flank and transition surface has time-varying characteristics, which directly affects friction and wear performance of the milling cutter.

A stepwise emergence of evolution in the RNA world
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

In this work we study the pullback dynamics of a class of nonlocal non-autonomous evolution equations for neural fields in a bounded smooth domain $\Omega$ in $\mathbb{R}^N$ \[ \begin{cases} \partial_t u(t,x) =- u(t,x) + \displaystyle\int_{\mathbb ...

The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Interim Report: Pilot Project – Technology Integration in Underserved Schools Using Thinkfinity [PDF]
This pilot project was conceived as a way to enable teachers in schools with fewer technical resources than typical public schools, or with special needs for students and teachers, to explore and utilize the resources of Thinkfinity in lessons and ...

Seismic stratigraphy of the Ontong Java Plateau [PDF]
The Ontong Java Plateau, a large, deep-water carbonate plateau in the western equatorial Pacific, is an ideal location for studying responses of carbonate sedimentation to the effects of changing paleoceanographic conditions.

In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...
