Spatial Patterns, Driving Forces, and Potential Grain Losses of Non‐Grain Production of Farmland in Central Yunnan Urban Agglomeration, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The expansion of farmland non‐grain production (NGP) poses a potential threat to food security and agricultural land protection, particularly in mountainous urban agglomerations. However, the utilization patterns, driving mechanisms, and associated production‐loss effects of farmland NGP in this specific regional context remain insufficiently ...

WBIM-GAN: A Generative Adversarial Network Based Wideband Interference Mitigation Model for Synthetic Aperture Radar

open access: yesRemote Sensing
Wideband interference (WBI) can significantly reduce the image quality and interpretation accuracy of synthetic aperture radar (SAR). To eliminate the negative effects of WBI on SAR, we propose a novel end-to-end data-driven approach to mitigate WBI ...

An Improved and Efficient Countermeasure against Power Analysis Attacks

open access: yes, 2008
. Recently new types of differential power analysis attacks (DPA) against elliptic curve cryptosystems (ECC) and RSA systems have been introduced. Most existing countermeasures against classical DPA attacks are vulnerable to these new DPA attacks which ...

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Fast Algorithm of Passive Bistatic Radar Detection Based on Batches Processing of Sparse Representation and Recovery

open access: yesRemote Sensing
In the passive bistatic radar (PBR) system, methods exist to address the issue of detecting weak targets without being influenced by non-ideal factors from adjacent strong targets.

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Effect of Veil Interlayer Type and Placement on the Mechanical Response of Carbon and Glass Fiber/Epoxy Composites

open access: yesPolymer Composites, EarlyView.
Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored

Using S-Rules to Fire Dynamic Countermeasure

open access: yes, 2017
We present a rule-based system to dynamically deploy countermeasures against privilege escalations where a rule includes some n-grams and a countermeasure. An n-gram consists of n consecutive attacks.
