Thermal Cracks of Carbide Face Milling Cutter

open access: yesBulletin of JSME, 1962
Under severe cutting conditions of carbide face-milling operation, cracks first come out almost perpendiculary to the cutting edge on both rake and relief surface of blades, and next, cracks parallel to the cutting edge appear according to circumstances. These cracks have negative effects on the durability of a cutter and especially when cutting fluids

Survival as a success in the face of a scarcity of resources [PDF]

open access: yes, 2002
From institutional, resource dependence and organizational ecology perspectives, there are two initial requirements for organizational survival: 1) there are sufficient resources in the niche, and 2) the organization can obtain these resources.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

open access: yesAdvanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Restoring freshwater habitat mosaics to promote resilience of vulnerable salmon populations

open access: yesEcosphere
Phenotypic diversity and abundance drive salmon resilience in the face of increasing environmental variability. But what happens when human activities fundamentally alter the habitat complexity that drives this diversity?

In Defense of Truth: Skepticism, Morality, and The Matrix [PDF]

open access: yes, 2002
The Matrix exposes us to the uncomfortable worries of philosophical skepticism in an especially compelling way. However, with a bit more reflection, we can see why we need not share the skeptic’s doubts about the existence of the world.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.
