ABSTRACTMate-allocation in breeding programs can improve progeny performance by exploiting non-additive effects. Breeding decisions in the mate-allocation approach are based on predicted progeny merit rather than parental breeding value. This is particularly attractive when non-additive effects are significant, and the best-predicted progeny can be clonally propagated, for example sugarcane. We compared mate-allocation strategies that leverage non-additive and heterozygosity effects to maximise sugarcane clonal performance to schemes that use only additive effects to maximise breeding value. We used phenotypes and genotypes from a population of 2,909 clones phenotyped in Australia’s sugarcane breeding program’s final assessment trials for three traits: tonnes of cane per hectare (TCH), commercial cane sugar (CCS), and fibre. The clones from the last generation of this data set were used as parents to simulate families from all possible crosses (1,225), each with 50 progenies. The breeding and clonal values of progeny were predicted using GBLUP (considering only additive effects) and the e-GBLUP model (incorporating additive, non-additive and heterozygosity effects). Integer linear programming was used to identify the optimal mate-allocation among the selected parents. Compared to the breeding value, the predicted progeny value of allocated crossing pairs based on clonal performance (e-GBLUP) increased by 57%, 12%, and 16% for TCH, CCS, and fibre, respectively. In our study, the mate-allocation strategy exploiting non-additive and heterozygosity effects resulted in better clonal performance. However, there was a noticeable decline in additive gain, particularly for TCH, which might have been caused by the presence of large epistatic effects. When crosses were chosen based on clonal performance for TCH, progenies’ inbreeding coefficients were found significantly lower than for random mating, indicating that utilising non-additive and heterozygosity effects has advantages for controlling inbreeding depression. Therefore, mate-allocation is recommended in clonal crops to improve clonal performance and reduce inbreeding.

ABSTRACTAccurate datasets are crucial for rigorous large-scale sequence-based analyses such as those performed in phylogenomics and pangenomics. As the volume of available sequence data grows and the quality of these sequences varies, there is a pressing need for reliable methods to swiftly identify and eliminate low-quality and misidentified genomes from datasets prior to analysis. Here we introduce a robust, controlled, computationally efficient method for deriving species-level population structures of bacterial species, regardless of the dataset size. Additionally, our pipeline can classify genomes into their respective species at the genus level. By leveraging this methodology, researchers can rapidly clean datasets encompassing entire bacterial species and examine the sub-species population structures within the provided genomes. These cleaned datasets can subsequently undergo further refinement using a variety of methods to yield sequence sets with varying levels of diversity that faithfully represent entire species. Increasing the efficiency and accuracy of curation of species-level datasets not only enhances the reliability of downstream analyses, but also facilitates a deeper understanding of bacterial population dynamics and evolution.

AbstractThe complex symbiotic relationship between the mammalian body and gut microbiome plays a critical role in the health outcomes of offspring later in life. The gut microbiome modulates virtually all physiological functions through direct or indirect interactions to maintain physiological homeostasis. Previous studies indicate a link between maternal/early-life gut microbiome, brain development, and behavioral outcomes relating to social cognition. Here we present direct evidence of the role of the gut microbiome in brain development. Through magnetic resonance imaging (MRI), we investigated the impact of the gut microbiome on brain organization and structure using germ-free (GF) mice and conventionalized mice, with the gut microbiome reintroduced after weaning. We found broad changes in brain volume in GF mice that persist despite the reintroduction of gut microbes at weaning. These data suggest a direct link between the maternal gut or early-postnatal microbe and their impact on brain developmental programming.

AbstractPrevious research has focused on the role of the extrastriate body area (EBA) in category-specific body representation, but the specific features that are represented in this area are not well understood. This study used ultra-high field fMRI and banded ridge regression to investigate the coding of body images by comparing the performance of three encoding models in predicting brain activity in ventral visual cortex and specifically the EBA. Our results suggest that EBA represents body stimuli based on a combination of low-level visual features and postural features.Author SummaryHistorically, research on body representation in the brain has focused on category-specific representation, using fMRI to investigate the most posterior body selective region, the extrastriate body area (EBA). However, the role of this area in body perception is still not well understood. This study aims to clarify the role of EBA, in coding information about body images. Using ultra-high field neuroimaging (fMRI) and advanced encoding techniques we tested different computational hypotheses to understand how body images are represented in EBA. Our results suggest that EBA represents bodies using a combination of low-level properties and postural information extracted from the stimulus.

AbstractMany species, such as fish schools or bird flocks, rely on collective motion to forage, prey, or escape predators. Likewise,Myxococcus xanthusforages and moves collectively to prey and feed on other bacterial species. These activities require two distinct motility machines enabling adventurous (A) and social (S) gliding, however when and how these mechanisms are used has remained elusive. Here, we address this long-standing question by applying multiscale semantic cell tracking during predation. We show that: (1) foragers and swarms can comprise A- and S-motile cells, with single cells exchanging frequently between these groups; (2) A-motility is critical to ensure the directional movement of both foragers and swarms; (3) the combined action of A- and S-motile cells within swarms leads to increased predation efficiencies. These results challenge the notion that A- and S-motilities are exclusive to foragers and swarms, and show that these machines act synergistically to enhance predation efficiency.

AbstractThe emergence of the anterior-posterior body axis during early gastrulation constitutes a symmetry-breaking event, which is key to the development of bilateral organisms, and its mechanism remains poorly understood. Two-dimensional gastruloids constitute a simple and robust framework to study early developmental events in vitro. Although spontaneous symmetry breaking has been observed in three dimensional (3D) gastruloids, the mechanisms behind this phenomenon are poorly understood. We thus set out to explore whether a controllable 2D system could be used to reveal the mechanisms behind the emergence of asymmetry in patterned cellular structures. We first computationally simulated the emergence of organization in micro-patterned mouse pluripotent stem cell (mPSC) colonies using a Turing-like activator-repressor model with activator-concentration-dependent flux boundary condition at the colony edge. This approach allows the self-organization of the boundary conditions, which results in a larger variety of patterns than previously observed. We found that this model recapitulated previous results of centro-symmetric patterns in large colonies, and also that in simulated small colony sizes, patterns with spontaneous asymmetries emerged. Model analysis revealed reciprocal effects between diffusion and size of the colony, with model-predicted asymmetries in small pattern sizes being dominated by diffusion, and centro-symmetric patterns being size-dominated. To test these predictions, we performed experiments on micro-patterned mPSC colonies of different sizes stimulated with Bone Morphogenetic Protein 4 (BMP4), and used Brachyury (BRA)-GFP expressing cells as pattern readout. We found that while large colonies showed centro-symmetric BRA patterns, the probability of colony polarization increased with decreasing sizes, with a maximum polarization frequency of 35% at ∼200μm. These results indicate that a simple molecular activator-repressor system can provide cells with collective features capable of initiating a body-axes plan, and constitute a theoretical foundation for the engineering of asymmetry in developmental systems.

PurposeThe objective of this study was to assess the incorporation of polyunsaturated omega 3 and omega 6 fatty acids in the eggs of Japanese quails (Coturnix coturnix japonica) fed with soybean, flaxseed and shark liver oils, as well as to assess their effects on the chemical composition and lipid quality of the yolks.Design/methodology/approachThe total of 252 units of quails were distributed in a completely randomized design with seven treatments and six replications, totaling 42 experimental design units. The sources of oils and their inclusions in the experimental diet were 2% of soybean oil (S), 2% of flaxseed oil (L) and 2% shark liver oil (T), obtained from the species Carcharhinus acronotus, and the mixtures of 1% S + 1% L (SL); 1% S + 1% T (ST); 1% L + 1% T (LT) and 0.67% S + 0.67% L + 0.67% T (SLT).FindingsThe proximate composition of the egg yolk was not changed to the supplementation of lipid sources added in quail diet. The total replacement of soybean oil by shark liver oil reduced the cholesterol content in the yolk by 19% (T = 282.97 mg cholesterol/100 g egg) and the addition of flaxseed oil produced eggs with greater amount of polyunsaturated fatty acids (PUFAs) (LS = 18.32%). The treatments with flaxseed oil and its mixtures (soybean oil + flaxseed oil and flaxseed oil + shark liver oil) effectively contributed to reducing the ω-6:ω-3 ratio and enriching the quail eggs with PUFAs, especially linolenic acid (18: 3n3c) and EPA (20: 5n3c).Originality/valueThus, manipulation in the diet of quails enriched the content of essential PUFAs and reduced the cholesterol content in the yolk. The flaxseed oil was the lipid source that influenced to improve the quality of the egg yolk. These results have practical applicability for the quail egg industry.

Published: December 2022

PurposeThe rise of a professional career presents women in today's public relations profession an intense challenge in balancing professional and family responsibilities. Therefore, this study is motivated to investigate female public relations professionals' perceptions of work–family conflict in their daily life. Specifically, the authors focused the research on women working in the professions of communication and public relations in the United States.Design/methodology/approachAn online survey was designed and conducted in the United States. The final sample includes 512 women working full-time in public relations and communication. In addition, the authors pre-specified several demographic quotas in sampling design in order to recruit a diverse group of female professionals nationwide.FindingsThe findings of this research study confirmed that female professionals have to constantly make changes to their plans for family activities when there is a conflict due to work-related duties. Such impact is particularly intense for professionals in the age bracket of 31–40. They have to use a wide variety of coping strategies to manage the work–family conflict. Findings in the present research study confirmed the critical role of mentoring in providing extra support and to help junior female professionals find coping solutions. Effective mentor–mentee networks can be established and used as valuable resources to support women in managing work–family conflict.Originality/valueBy investigating current female professionals' perceptions on work–life conflict and their adoption of relevant coping strategies in the workplace, this research provides solid evidence that organizations should dedicate efforts in providing strong support in programs and policies and makes the options available to female professionals at all levels. The present research highlights the importance of building mentor–mentee relationships as an effective supportive approach when managing work–family conflict.
“I will learn from my mistakes if we are close and supportive”: a moderated-mediating model of learning from mistakes
Authors: Kwok Man Lung Jonathan , Kwong Raymond 
Published: December 2022

PurposeThis study aims to identify the antecedents of learning from mistakes within the student group work setting. Specifically, this study provides empirical evidence of how team–member exchange (TMX) positively leads to learning from mistakes via person-focused interpersonal citizenship behaviours (ICBs) and of the boundary condition of intellect of this indirect relationship.Design/methodology/approachCross-sectional survey data were collected from 189 new business undergraduate students at a Hong Kong higher education institute. PROCESS Macro (Hayes, 2013) and bootstrapping with 5,000 resamples were conducted to analyse the moderated mediation model.FindingsThe authors found that high levels of TMX within a group positively related to person-focused ICBs and learning from mistakes. Moreover, the bootstrapping results showed that there was an indirect effect of TMX and learning from mistakes via person-focused ICBs. The presence of students with high intellect strengthened this indirect relationship.Originality/valueWhereas many studies have examined the development of students’ employability skills, most have ignored the importance of learning from mistakes, which is considered to be a soft employability skill and an important attribute in the workplace. Moreover, the factors that facilitate students’ learning from mistakes are unclear. This study is the first to identify the antecedents of learning from mistakes by adopting social exchange, reciprocity and social information processing (SIP) theories.

Published: December 2022

Purpose
The purpose of this study is to cover the influence of selected printing parameters at a macro and micro-geometrical level, focusing on the dimensions, geometry and surface of printed parts with short carbon fibers reinforced PLA. For this case study, a hollow cylindrical shape is considered, aiming to cover the gap detected in previous works analyzed.

Design/methodology/approach
Nowadays, additive manufacturing plays a very important role in the manufacturing industry, as can be seen through its numerous research and applications that can be found. Within the engineering industry, geometrical tolerances are essential for the functionality of the parts and their assembly, but the variability in three-dimensional (3D) printing makes dimensional control a difficult task. Constant development in 3D printing allows, more and more, printed parts with controlled and narrowed geometrical deviations and tolerances. So, it is essential to continue narrowing the studies to achieve the optimal printed parts, optimizing the manufacturing process as well.

Findings
Results present the relation between the selected printing parameters and the resulting printed part, showing the main deviations and the eligible values to achieve a better tolerance control. Also, from these results obtained, we present a parametric model that relates the geometrical deviations considered in this study with the printing parameters. It can provide an overview of the piece before printing it and so, adjusting the printing parameters and reducing time and number of printings to achieve a good part.

Originality/value
The main contribution is the study of the geometry selected under a 3D printing process, which is important because it considers parts that are created to fit together and need to comply with the required tolerances. Also, we consider that the parametric model can be a suitable approach to selecting the optimal printing parameters before printing.

Pre-Exhaust-Gas-Pressure Measurements for Indicating Diesel-Engine Performance
Authors: Jennings B. H. , Jackson T. E. 
Published: December 2022

Abstract
The pressure existing just before exhaust in a Diesel engine is shown to be significant as a means of indicating load adjustments in a multicylinder engine. This paper explains the theory and method used in obtaining these pre-exhaust pressures, along with the supporting data from an extensive series of tests. These tests were conducted at Lehigh University on both two-stroke-cycle multicylinder engines and a four-stroke-cycle single-cylinder C.F.R. test engine. Under definite known conditions of injection, timing, and compression ratio it was found possible to evaluate both indicated and brake horsepower in terms of pre-exhaust pressure. Experimental work in progress shows that the same method is applicable to spark-ignition engines.

Hydraulic Characteristics of Fuel-Injection Nozzles
Authors: Zahn O. F. 
Published: December 2022

Abstract
This paper makes use of both new and previously published material in studying the hydraulic actions and limitations of fuel-injection nozzles. The primary function, hydraulically, of such a nozzle is to inject all portions of the fuel at velocities above a certain minimum necessary for atomization. The most serious factor tending to prevent this is the wide range of speeds found in present small Diesel engines. It is found that the closed nozzle meets the requirements of speed flexibility better than the simple open type, and that the variable-area-orifice closed nozzle is a further improvement over the plain-hole closed nozzle. The effects on the rate of injection and minimum regular quantity of injection are noted.
The Effect of Diametral Clearance on the Load Capacity of a Journal Bearing
Authors: Burwell J. T. 
Published: December 2022

Abstract
It has been found that there is an optimum value of the diameter-clearance ratio of a journal bearing for any given applied load. When the ratio has this value, operation is characterized by a minimum temperature rise in the bearing and a constant value of the Sommerfeld variable (DC)2μNP. These values of the diameter-clearance ratio, while considerably larger than those used in commercial practice, are quite possible of attainment by present machining methods. The use of these closer fits will result in increased load capacities and lower operating temperatures. The present paper is devoted to an investigation of the effect of D/C on the load capacity in a quantitative manner, considering both the hydrodynamic and thermodynamic aspects of bearing operation.
Some Problems in the Selection and Operation of Centrifugal Pumps for Oil and Gasoline Pipe Lines
Authors: Hollander A. 
Published: December 2022

Abstract
During the 15 years since they were first introduced, high-pressure motor-driven centrifugal pumps have been adopted to an ever greater extent in crude-oil trunk lines. Since the inception of gasoline trunk lines six years ago, centrifugal pumps have been exclusively used in this service. This paper deals with the basic principles of developing pumping stations of suitable capacity under present conditions and mentions future improvements contemplated. Today, trunk-line centrifugal pumps include units having capacities from 5000 to 125,000 bbl per day, working against pressures of 300 to 1100 psi, driven by two-pole induction motors of 200 to 900 hp. Units proposed for the National Defense Pipe Line will have 250,000 bbl per day capacity against 775 psi, operating three single-stage pumps in series, each driven by a 1300-hp motor. The procedure followed by the pump designer in developing units to meet given requirements is outlined, together with details of the resulting characteristics. Discussion of trunk-line operating schedules is included, and finally a method is given for solving pipe-line-pumping problems.
