Detection, identification and audification of pulsatile structures using proximal data acoustic sensing

Current Directions in Biomedical Engineering
This work demonstrates the detection and identification of pulsatile activity using proximal vibroacoustic sensing in laparoscopic instruments. A controlled setup simulating vascular pulsations was used to evaluate two signal processing methods ...

Using Color, Texture and Object-Based Image Analysis of Multi-Temporal Camera Data to Monitor Soil Aggregate Breakdown

Sensors, 2017
Remote sensing has shown its potential to assess soil properties and is a fast and non-destructive method for monitoring soil surface changes. In this paper, we monitor soil aggregate breakdown under natural conditions.

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Monitoring Strawberry Plants’ Growth in Soil Amended with Biochar

AgriEngineering
This study evaluated the impact of biochar on the growth of strawberry plants, combining visual and proximal sensing monitoring. The plants were rooted in soil enriched with biochar, derived from pyrolysis of soft wood at 550 °C and applied in two doses (

Proximal Sensing of Plant Diseases

, 2014
Proximal sensing techniques have a large potential in surveying crops for the occurrence of diseases varying in spatial and temporal distribution within crops. Incidence of plant diseases results from crop status, the presence of inoculum, and suitable abiotic environmental factors, and often is heterogeneous in the field. Various technical sensors may

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Assessment of Citrus Water Status Using Proximal Sensing: A Comparative Study of Spectral and Thermal Techniques

Land
Early detection of plant water status is crucial for efficient crop management. In this research, proximal sensing tools (i.e., hyperspectral imaging HSI and thermal IR camera) were used to monitor changes in spectral and thermal profiles of a citrus ...

Temporal and Spectral Optimization of Vegetation Indices for Estimating Grain Nitrogen Uptake and Late-Seasonal Nitrogen Traits in Wheat

Sensors, 2019
Grain nitrogen (N) uptake (GNup) in winter wheat (Triticum aestivum L.) is influenced by multiple components at the plant organ level and by pre- and post-flowering N uptake (Nup). Although spectral proximal high-throughput sensing is promising for field

On-line measurement of selected soil properties towards the refinement of Nitrogen fertilisation management in vegetable crops [PDF]

, 2015
Fertiliser applications in vegetable crops are one of the main input costs of production. Thematic soil maps have been widely used for decades to characterise soil nutrients and, therefore, apply variable rate fertilisers.
