African Dairy Genetic Gains (ADGG) at a glance—Optimising productivity and resilience of dairy cattle for the tropics: Genomic selection of cross-bred bulls in East Africa
This project aims to optimize dairy cattle productivity and adaptation in East Africa through genomic selection of cross-bred bulls. The challenges include farmers extracting low profits from their animals and a lack of pedigree records. The project will:
1) Identify genomic regions associated with productivity and resilience traits to incorporate into genomic estimated breeding values.
2) Show that genomic prediction accuracies for young bulls without records are around 40% for a wide range of cross-bred bulls, allowing elimination of the worst and selection of the best.
3) Develop a low-density SNP chip combined with imputation to enable genomic prediction.

Beef Cattle Production and Wealth Creation: Evidence from Improved Boran Catt...Premier Publishers
The study was conducted to assess Improved Boran production and their crosses under ranching conditions. Growth performance, reproductive performance, carcass traits and their profitability were analyzed using primary data from Beef Research Institute, Lanet Centre and secondary data from desktop study. Cash flow analysis was used to compute the profitability of Improved Borans under free range production system as well as a hypothetical case of intensive system. The Boran breeding bulls, steers, were identified as the major receipts. The Centre reported the average birth, weaning, and yearling steer weights of Improved Boran at 26.8kg, 149kg (7 months) and 202 kg respectively. Yearling steer weights for Boran crossed with Sahiwal weighed 207kg. Calve survival rate was 94.20% and 95.2% for Improved Boran and Boran crossed with Sahiwal respectively. A gross profit at 99.8% and 98.6% of total unit operating cost for Improved Boran and Boran crosses enterprises respectively was reported under free range system. A hypothetical case of 100 Improved Boran steers under feedlotting for three months reported gross profit at 65.6% of total unit operating cost. However, the unit cost of production in free range system was lower than intensive and the entrepreneur should seize the opportunity of economics of scale.

It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Optimizing productivity
and adaptationA Screening Exotic bulls
for adaptability in AfricaB
The Challenge
Farmers extracting low profits from their dairy
animals
High and intermediate grade cows are reared in
low and average production environments
No pedigree records are kept so most farmers do
not know the genetic make up of their animals
Heifers and crossbred bulls with breed composition
that is appropriate to farmers’ circumstances are
needed, but are not readily available
Identify genomic regions associated with
productivity and resilience (i.e. number
of times animals are treated, reproductive
performance and longevity)
Incorporate GWAS results into GEBVs
computation to optimize productivity
and functionality
Accuracies of genomic prediction for young bulls
with no records are reasonable (about 40% across
a wide range of cross-bred bulls)
The SNP chip could be used initially to eliminate
the worst bulls and select the best young bulls
for AI
Genomic prediction can be achieved using a low
density (3-4K) SNP chip combined with imputation
exploiting the covariance between SNPs
Use the information from A to develop a genomic
tool to screen exotic bulls for adaptability and
performance in Africa
Design strategic mating plan for selected bulls and
indigenous cows and select progeny with optimum
combination of desired traits
Use AI to deliver millions of semen doses with
the aim of establishing tropically adapted cattle
In addition to organizations recognized for specific projects and outputs, we thank all donors which globally supported the work of ILRI and its partners through their contributions to the CGIAR system
