High‐Performance Graphene‐Based Gas Sensors with Pulsed Heating and AI Processing

Advanced Sensor Research, EarlyView.
Ultra‐low power graphene‐based MEMS gas sensors functionalized with vanadium pentoxide or copper‐manganese oxide are reported. Operated in pulsed heating mode, the sensors produce transient conductance profiles analyzed via discrete Fourier transform and compact neural networks.

RTDGPS Implementation by Online Prediction of GPS Position Components Error Using GA-ANN Model [PDF]

Journal of Electrical and Computer Engineering Innovations, 2013
If both Reference Station (RS) and navigational device in Differential Global Positioning System (DGPS) receive signals from the same satellite, RS Position Components Error (RPCE) can be used to compensate for navigational device error.

A Fusion Methodology to Bridge GPS Outages for INS/GPS Integrated Navigation System

IEEE Access, 2019
The performance of an inertial navigation system (INS) and global positioning system (GPS) integrated navigation system is reduced during GPS outages. To bridge GPS outages, a fusion methodology to provide pseudo GPS position information is proposed. The

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

Advanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Microbial Community Succession Sustains Fish Diversity in the Upper Yangtze River Reserve

Advanced Science, EarlyView.
Critical for river ecosystem sustainability, fish diversity relates to multitrophic microbes. This upper Yangtze FNNR study used eDNA to examine microbial succession‐fish links, finding key drivers, distinct assembly processes, and that microbial cross‐trophic interactions benefit fish, offering conservation insights.

Regulating PPARG Reduces Lipid Accumulation in Microglia and Promotes Functional Recovery After Spinal Cord Injury

Advanced Science, EarlyView.
Macrophages infiltrate the spinal cord post‐injury, decreasing over time. Microglia phagocytose myelin debris, increasing lipid accumulation. Macrophage deletion improves outcomes, while microglial deletion worsens them. The LD+ microglia subtype shows abnormal Pparg signaling.

Intrinsic Gaussian processes on complex constrained domains [PDF]

, 2018
We propose a class of intrinsic Gaussian processes (in-GPs) for interpolation, regression and classification on manifolds with a primary focus on complex constrained domains or irregular shaped spaces arising as subsets or submanifolds of R, R2, R3 and ...

GPS Data Modeling and GPS Noise Analysis

2006 IEEE 14th Signal Processing and Communications Applications, 2006
In this study, we model the daily recordings of the GPS (Global Positioning System) data, and examine the noise characteristics of its residual signal (which is the difference between the real data and the model.) Here, two main problems are studied: The first one is the issue of selecting proper model parameters that are fitted to GPS data. Note that,
