One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Focused Ultrasound for Essential Tremor in Denmark: Results After 1 Year of Follow‐Up

Movement Disorders, EarlyView.
Abstract Background Essential tremor (ET) is the most common hyperkinetic movement disorder. Magnetic resonance‐guided focused ultrasound thalamotomy (MRgFUSTh) has become an established therapy in drug‐refractory tremor as one treatment option. Here, we present the results of a large cohort of MRgFUSTh‐treated ET patients followed‐up 1 year post ...

Uplink Access Schemes for LTE-Advanced

IEICE Transactions on Communications, 2009
The 3GPP LTE-Advanced has been attracting much attention recently, where the channel bandwidth would be beyond the maximum bandwidth of LTE, 20MHz. In LTE, single carrier-frequency division multiple access (SC-FDMA) was accepted as the uplink access scheme due to its advantage of very low cubic metric (CM). For LTE-A wideband transmission, multicarrier

Optimized Gradient Waveforms for Tensor‐Valued Diffusion MRI Under Time‐Dependent Diffusion Using Double‐Isotropic Matched Encoding (DIME)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Spherical and linear b‐tensor encoding (STE and LTE) enables quantification of microscopic diffusion anisotropy and diffusional variance. However, such waveforms are often variably sensitive to time‐dependent diffusion, causing rotational variance and spectral mismatch.

Analysis of Macro-Diversity in LTE-Advanced

KSII Transactions on Internet and Information Systems, 2011
Coordinated Multi-Point (CoMP) transmission / reception is being studied in Long Term Evolution-Advanced (LTE-A) for future evolution of the 3 rd Generation Partnership Project (3GPP) LTE. Support of soft handover is essential for improving the performance of cell edge users.

Centralized coordinated scheduling in LTE-Advanced networks [PDF]

EURASIP Journal on Wireless Communications and Networking, 2017
This work addresses the problem associated with coordinating scheduling decisions among multiple base stations in an LTE-Advanced downlink network in order to manage inter-cell interference with a centralized controller. To solve the coordinated scheduling problem an integer non-linear program is formulated that, unlike most existing approaches, does ...

String‐Stable Platooning Control of Connected Automated Vehicles Under Non‐Uniform Stochastic Communication Delays

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper is concerned with the platooning control problem of connected automated vehicles (CAVs) under non‐uniform stochastic vehicle‐to‐vehicle (V2V) communication delays. Most existing relevant studies assume uniform or deterministic or slowly varying delays, or design platoon controllers based on worst‐case delay bounds, resulting in ...
