Climatic controls on soil production, transport and chemical erosion: Insights from modelling topography, soils and cosmogenic nuclides at Little Lake, Oregon

Earth Surface Processes and Landforms, Volume 50, Issue 14, November 2025.
We conducted landscape evolution model simulations with climate‐sensitive hillslope soil transport, soil production and mineral dissolution/alteration while tracking a 10Be tracer. We incorporated sub‐models for frost heaving and frost cracking. In our reference simulation where temperature controlled processes and a lake provided a new base level ...

Direct torque control of multiphase doubly converter-fed asynchronous machines incorporating the harmonic torques [PDF]

, 2018
Doubly fed asynchronous machines have an outstanding property: they can be operated up to twice rated speed delivering full rated torque. This paper presents, for the first time in the literature, a control system for multiphase asynchronous machines fed

Analysis and Mitigation of Excess Phase Noise and Spurs in Digital-to-Time-Converter-Enhanced Fractional- N Frequency Synthesizers

IEEE Transactions on Circuits and Systems Part 1: Regular Papers
Digital-to-time converters (DTC’s) used in fractional-N phase locked loops (PLL’s) aim to zero the quantization error (QE) introduced by the divider controller in order to recover integer-N phase noise (PN) performance.

Heterogeneity of Extracellular Vesicles and Non‐Vesicular Nanoparticles in Glioblastoma

Journal of Extracellular Vesicles, Volume 14, Issue 10, October 2025.
ABSTRACT It is increasingly clear that intercellular communication is largely mediated by lipid‐bilayer, membrane‐bound extracellular vesicles (EVs) and amembranous, non‐vesicular extracellular particles (NVEPs), including exomeres and the recently identified supermeres.

A Process Based Modeling Approach to Assess Temperature Impacts of Riparian Vegetation Management in a Southwestern Wisconsin Trout Stream

River Research and Applications, Volume 41, Issue 8, Page 1749-1765, October 2025.
ABSTRACT Rising water temperatures driven by climate change threaten culturally and economically important salmonid fisheries throughout the Upper Midwest. Unsuitable thermal regimes degrade the effectiveness of habitat restoration projects in the region, thus strategies for mitigating peak summer stream temperatures are of interest to state and non ...

A predictive control with flying capacitor balancing of a multicell active power filter [PDF]

, 2008
Unlike traditional inverters, multicell inverters have the following advantages: lower switching frequency, high number of output levels, and less voltage constraints on the insulated-gate bipolar transistors.

A Force Myography (FMG) Armband Based on Micro‐Structured Textile‐Pressure Sensors for Human‐Machine Interface (HMI)

Advanced Sensor Research, Volume 4, Issue 9, September 2025.
This study introduces a textile‐based capacitive pressure sensor featuring a triangular prism microstructure, which significantly enhances sensitivity to 5.52% kPa−¹ and supports a wide sensing range up to 330 kPa. The sensor's performance is validated in a 4‐channel capacitive pressure‐based force myography (cFMG) armband for gesture recognition ...

Direct torque control scheme for a six-phase induction motor with reduced torque ripple [PDF]

, 2017
This paper presents an improved direct torque control (DTC) method for an asymmetrical six-phase induction motor using a two-level six-phase inverter. As is well-known, a simple extension of three-phase direct torque control technique to an asymmetrical ...
