Utilizing (Al, Ga)2O3/Ga2O3 superlattices to measure cation vacancy diffusion and vacancy-concentration-dependent diffusion of Al, Sn, and Fe in \b{eta} -Ga2O3 Open
Diffusion of native defects such as vacancies and their interactions with impurities are fundamental in semiconductor crystal growth, device processing, and long-term aging of equilibration and transient diffusion of vacancies are rarely i…
Non-invasive Gene Expression Analysis Rules Out Melanoma with High Negative Predictive Value Regardless of Skin Phototype Open
Non-invasive assessment of clinically atypical, pigmented skin lesions to rule out melanoma with a negative predictive value (NPV) of 99% by detecting expression of LINC00518 and PRAME (2-GEP assay) is gaining adoption. These melanomaassoc…
Grape cultivars adapted to hotter, drier growing regions exhibit greater photosynthesis in hot conditions despite less drought-resistant leaves Open
Background and Aims Many agricultural areas are expected to face hotter, drier conditions from climate change. Understanding the mechanisms that crops use to mitigate these stresses can guide breeding for more tolerant plant material. We t…

Dynamic <i>R</i> <sub>ON</sub> Free 1.2-kV Vertical GaN JFET Open
Dynamic on-resistance (RON) or threshold voltage (VTH) instability caused by charge trapping is one of the most crucial reliability concerns of some GaN high-electron mobility transistors (HEMTs). It has been unclear if this issue can be r…
A muscadine locus confers resistance to predominant species of grapevine root-knot nematodes (<i>Meloidogyne</i> spp.) including virulent populations Open
Root-knot nematodes (RKNs) Meloidogyne spp. are extremely polyphagous pests and four species severely affect grapevines throughout the world: M. arenaria, M. incognita, M. javanica and M. ethiopica. Californian populations of M. arenaria a…
SPGNN-API: A Transferable Graph Neural Network for Attack Paths Identification and Autonomous Mitigation Open
Attack paths are the potential chain of malicious activities an attacker performs to compromise network assets and acquire privileges through exploiting network vulnerabilities. Attack path analysis helps organizations to identify new/unkn…
