Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Questioning Your Brilliance in Physics: Differential Shifts in Fixed Mindsets by Grade and Gender

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Students' domain‐specific mindsets and their beliefs about their capacity to improve through effort play a crucial role in shaping their experiences and decisions to persist in STEM disciplines. Physics is generally seen as a field requiring innate brilliance, which can reinforce fixed mindsets, particularly after initial setbacks in ...

Analogies and differences between the logic behind statistical hypothesis testing and proofs by contradiction: What can we learn from them?

Teaching Statistics, EarlyView.
Abstract Statistical hypothesis testing (SHT) is widely employed across numerous scientific disciplines, and a clear understanding of its underlying logic is essential for the broader scientific community. Here, drawing upon both epistemological and statistical perspectives, we aim to clarify—primarily for educational purposes—the logical relationship ...

Pressure Pulses Generated by Wire‐Guided Discharges in Water

High Voltage, EarlyView.
ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Changing practices, not just rules: Rethinking the institutionalisation of deliberative engagement

Australian Journal of Public Administration, EarlyView.
Abstract When Victoria introduced legislation requiring all 79 councils to adopt deliberative engagement, 92% continued practices the legislation had just removed. This paradox reveals a fundamental challenge in embedding democratic innovations within existing systems of government: legislation signals commitment but cannot disrupt entrenched ...

Mitigating Disinformation with Civic Constitutionalism: The Case Study of Taiwan

Global Policy, EarlyView.
ABSTRACT Amid growing concerns over information integrity, disinformation has evolved into a broader and more complex phenomenon now recognized as Foreign Information Manipulation and Interference (FIMI), posing significant threats to democratic governance.
