Summary: In this paper, an alternative approach based on the generalized additive models for location, scale, and shape (GAMLSS) framework is proposed to create reference growth curves for female Hereford cattle breed. This methodology overcomes some known issues in quantile regression and can handle complex growth curves, heteroskedasticity, and skewed data. The application of this approach demonstrates the direct impact of animal age on the median, variability, and skewness characteristics of the growth curve. This method has significant implications in the study of animal and plant growth.

Summary: The study constructed a nonlinear mixed mapping framework to explore the genetic mechanisms regulating the multiphasic growth changes between stem diameter and stem height in forest trees. Several key quantitative trait loci were found to interpret the process and pattern of stem wood growth, and the timing and pattern of the vegetative phase transition were quantified. Additionally, the genetic machinery of significant loci was visualized, and the utility of the new mapping framework was validated through computer simulations.

Summary: Plant growth is a complex process that requires understanding to maximize crop potential. Modeling is an essential tool for characterizing and predicting plant growth, and this study aimed to apply and evaluate Logistic and Gompertz models for sunflower growth. Data from trials with three sunflower cultivars were analyzed, and the models were fitted using ordinary and generalized least squares methods. The inclusion of a power structure in the models improved the fit. The Logistic model was best for the cultivars Aguara 6 and Nusol 4510, while the Gompertz model was best for the Rhino cultivar.

Summary: This study demonstrates that factors such as poor ewe nutrition, birth type, rear type, and sire breed can have a significant impact on lamb growth. It suggests that genetic potential for lamb growth can be moderated by environment, multiple births, and sire type. The study highlights the need for lamb producers to have realistic expectations of lamb growth and consider mitigation strategies such as precision feeding or alternate breeds.

Summary: This study demonstrates that clinical anaplasmosis reduces breeding soundness in beef bulls. Anaplasmosis should be considered as a possible cause for decreased semen quality, especially in endemic areas.

Summary: This study investigates the effect of higher order continuity in the solution field using NURBS basis function in isogeometric analysis for elastostatic beams. The authors propose a reduced degree of basis functions for the stress resultants and strains of the beam, which significantly improves computational efficiency and accuracy. The results demonstrate the superior accuracy of isogeometric analysis over conventional finite element analysis.

Summary: A genome-wide association study was conducted to identify genetic variants associated with reproduction traits in South African Bonsmara cattle. Multiple candidate genes and quantitative trait loci were identified, many of which were close to genes known to be associated with carcass quality, fertility, growth, and milk-related traits. Additionally, several novel genes that had not been reported in beef cattle populations were also found.

Summary: Mixed nonlinear models combine mixed models with nonlinear models, allowing for the consideration of nonlinear regression function parameters as both fixed and random effects. This study compared the use of different nonlinear functions in fixed and mixed linear models to determine the body growth of Nelore cattle. The Brody function yielded the best adjustments, reducing residual variance by 79% for males and 83% for females. Rating: 8/10

Summary: In this study, a new metric called regression on expected feed intake (ReFI) was introduced to evaluate the efficiency of feed utilization in dairy cows. Compared to other metrics such as residual feed intake (RFI) and genetic residual feed intake (gRFI), ReFI showed higher genetic variation and heritability in measuring feed efficiency. Selection based on ReFI breeding values resulted in higher milk production and a greater increase in efficiency compared to selection based on RFI or gRFI values.

Summary: In this paper, a novel two-degree-of-freedom (TDOF) nonlinear energy harvester without internal resonance is proposed to achieve broadband harvesting characteristic. To demonstrate the performance, a TDOF nonlinear electromagnetic harvester is designed and analyzed using the harmonic balance method. The results show that the proposed harvester enhances the bandwidth of energy harvesting compared to conventional models.

Summary: The use and application of different nonlinear mixed models were evaluated to describe the growth curve of meat-type quails according to gender, comparing them with nonlinear fixed models. A total of 15,002 and 15,408 records of males and females were used. Nonlinear models (Brody; Gompertz; Logistic, Morgan-Mercer-Flodin, Richards and Von Bertalanffy) were used to regress body weights on age, with fixed parameters and random effects for asymptotic weight and maturity rate. The model that used the Morgan-Mercer-Flodin function with the inclusion of asymptotic weight as a random effect was considered the best-fitting model for both genders.

Summary: This study aimed to evaluate the growth ability of Czech Fleckvieh bulls in modern stable conditions and analyze the influence of their breeding lines. The results showed that the genetic predisposition for growth ability of dual-purpose Fleckvieh cattle was attenuated in the standardized conditions of a modern stable with good housing and nutrition.
