Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Soybean Row Spacing and Seeding Rate

, 2018
Recommendations for soybean seeding rates have been targeted between 125,000 and 140,000 seeds/acre with the objective of targeting a final plant population of at least 100,000 plants/acre. It is understood a 15-in. row spacing has approximately 4.5 bushels/acre higher yields than 30-in. row spacing.

On-Farm Corn Row Spacing Trials

, 2015
Over the past several decades there has been a shift in corn row spacing from the traditional 40-in. rows that were needed so horses could fit between the rows, to 38-in., 36-in., and the most popular 30-in. rows. The narrow row spacing usually has resulted in increased yields due to it allowing more space between the plants within the row.

Effect of periodic vibration-isolation piles on soil vibration in deep-buried tunnels of suburban railways

Science Progress
This study aims to investigate the impact of isolation piles on soil vibrations in the environment surrounding suburban railways. Initially, a comprehensive numerical model of the train was established to simulate the wheel-rail interaction forces, which

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...

Row Spacing with Variable Seeding Rates

, 2008
Current row widths employed by producers typically vary from 15 in. to 38 in., with most producers at 30 in. today. Yet more and more acres are being converted to narrower row widths(most often 15 in. or 20 in.). Numerous advantages exist with narrower row widths.

Effects of plant density on alfalfa (Medicago sativa L.) seed yield in western Heilongjiang areas

Open Life Sciences, 2023
Alfalfa (Medicago sativa L.) is known as the “king of forages”. The aim of the current study is to determine the optimum planting density as the key cultivation technique for high yield of alfalfa seed.
