Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

Small Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Steganalysis of LSB matching in grayscale images [PDF]

IEEE Signal Processing Letters, 2005
We consider the problem of detecting spatial domain least significant bit (LSB) matching steganography in grayscale images, which has proved much harder than for its counterpart, LSB replacement. We use the histogram characteristic function (HCF), introduced by Harmsen for the detection of steganography in color images but ineffective on grayscale ...

Robust steganographic framework for securing sensitive healthcare data of telemedicine using convolutional neural network

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Data is the key element that runs the modern society. Large amounts of data are being released day by day as a result of many activities. The digital data is transferred through the Internet which may be vulnerable to attacks while transmitting. Especially, the medical data is observed to be of at most importance.

School Board Elections in England and Wales, 1870–1902: An Electoral Experiment?

History, EarlyView.
Abstract The 1870 Elementary Education Act enabled the creation of school boards in England and Wales. Members were directly elected by the cumulative vote. This method gave each individual voter as many votes as there were seats on a school board, in some cases up to fifteen.

Natural History of Recurrent Acute Pancreatitis: Implications for Interventional Trial Design

Alimentary Pharmacology &Therapeutics, EarlyView.
In this nationwide cohort of 6894 patients with recurrent acute pancreatitis, recurrence risk increased progressively with each episode and occurred most frequently within the first year. Successive episodes were separated by shorter intervals, indicating an accelerating disease course and highlighting the importance of early preventive interventions ...
