No pain, more gain? Evaluating pain alleviation post equine orthopedic surgery using subjective and objective measurements
Publicado 2016“…The study used three subjective modalities and one objective modality to score pain: a composite Equine Pain Scale (EPS) score based on blinded-rated video footage; an Arthro and a VAS score as proxies for tissue damage; and an objective optical symmetry measurement (OS) score to evaluate low-grade lameness at walk. …”

Simplifying plant gene silencing and genome editing logistics by a one-Agrobacterium system for simultaneous delivery of multipartite virus vectors
Publicado 2022“…The system was successfully used in Nicotiana benthamiana for launching TRV infection, for recombinant protein production, as well as for robust virus-induced gene silencing (VIGS) of endogenous transcripts using bacterial suspensions at low optical densities. JoinTRV-mediated delivery of single-guide RNAs in a Cas9 transgenic host allowed somatic cell editing efficiencies of ≈90%; editing events were heritable and >50% of the progeny seedlings showed mutations at the targeted loci.…”

Visual cues from different trap colours affect catches of Sahlbergella singularis (Hemiptera: Miridae) in sex pheromone traps in Cameroon cocoa plantations
Publicado 2020“…Reflectance peaks exceeded 100% of the incident light in the 400–450 nm range from the white, suggesting the presence of optical brighteners. Trap catches support the hypothesis that S. singularis ocelli are more responsive to light of shorter wavelengths. …”

Mapping of smallholder oil palm plantation and development of a growth model
Publicado 2018“…Smallholder plantation accounts for 39% of total oil palm plantation in Indonesia, which is currently estimated at 12 million ha.Limited information on spatial distribution of smallholder oil palm and the growth of plantation pose a great challenge for providing information in scientific based.Therefore, information on smallholder oil palm plantation are necessary and they will give valuable input for policy maker and related stakeholders.This study is aimed to generate smallholder oil palm distribution map using optical satellite data of SPOT 7 and investigate the backscatter values of ALOS PALSAR-2 with height and age of oil palm in mineral soil and peatland.We mapped 46,756 ha of smallholder plantation or about 18% of total oil palm plantation in district of Kotawaringin Barat, Central Kalimantan province and 14% of which is located on peatland area.From the result, height to age mineral soil has a strong relationship with R 2 value 0.80 but weak in peatland with R 2 value 0.31.Relationship between height and backscatter in mineral soil has R 2 value 0.43 for HH and 0.30 for HV and in peatland 0.28 for HH and 0.15.Relationship between age and backscatter in mineral soil has moderately strong correlation with R 2 value 0.55 for HH and 0.37 for HV and in peatland 0.36 for HH and 0.28.In all relationship, independent variables are statistically significant with Significance-F value lower than 0.05.In general, height, age, and backscatter relationship in peatland is lower than in mineral soil.Backscatter value can be useful for studying height and age of smallholder oil palm.Further studies are suggested to involve more potential variables and utilize multi temporal datasets in determining height and age of oil palm trees using backscatter values.…”

Assessing methane emissions from rice fields in large irrigation projects using satellite-derived land surface temperature and agronomic flooding: A spatial analysis
Publicado 2024“…Synthetic aperture radar (SAR) imagery, notably Sentinel-1A’s C-band, VV, and VH polarized SAR, has emerged as a crucial tool for mapping rice fields, especially in regions where cloud cover hinders optical imagery. Employing multi-temporal characteristics, SAR data were regularly collected and parameterized using MAPscape-Rice software, which integrates a fully automated processing chain to convert the data into terrain-geocoded σ° values. …”

Estimating global warming potential for agricultural landscapes with minimal field data and cost
Publicado 2015“…We used the DeNitrification-DeComposition (DNDC) model software to simulate crop growth and carbon and nitrogen cycling to estimate net GHG emissions, with information based on the mapping of cropping patterns over time using multi- resolution and multi-temporal optical remote sensing imagery. We estimated a mean net emission of 78,620 tCO2e/yr (tons of carbon dioxide equivalents per year) with a 95% confidence interval of 51,212-106,028 tCO2e/yr based on uncertainties in our crop mapping and soil data. …”
