description: A total of 2,880 one-day-old male and female broiler chicks from two breeds, Ross308 and Cobb500 were randomly assigned to 72 pens. Broilers were offered three diets: a wheat-soybean diet without (CO), or with either a probiotic (probiotic; 2.4 x 109 CFU/kg diet of Bacillus subtilis DSM32324 and DSM32325 and B. amyloliquefaciens DSM25840) or a phytobiotic (phytobiotic; grape extract with 165 ppm procyanidin and 585 ppm polyphenol) product. The trial was conducted with a 3 × 2 × 2 factorial arrangement of diet, breed and sex in a completely randomized design and consisted of 6 replicate-pens per treatment (40 birds per pen). At day 7, 21, and 35, one chicken per pen was slaughtered for caecal sampling to quantify bacterial metabolites (digesta) as well as evaluate mRNA abundance and histomorphology (tissue). Data were subjected to ANOVA using GLM procedure to evaluate age, diet, breed and sex and their interactions. Spearman’s correlation (r) was analyzed between metabolite concentration and mRNA abundance. Overall, the concentration of short chain fatty acids increased with age, while lactate decreased from day 7 to 21 (p < 0.05). The mRNA abundance of IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17α, IL-18, IFN-γ and TGF-β2 increased with age but IL-1β and TNF-α increased in abundance from day 7 to 21 and then decreased (p < 0.05). Abundance of MUC2 and CLDN5 increased after day 21 (p < 0.05). Caecal crypt depth increased with age (p < 0.05). Acidic goblet cell (GC) number peaked at day 21 (p < 0.05), while mixed GC number was not affected by age. A few impacts of breed, diet and interactions on the investigated variables showed no meaningful biological pattern. Propionate positively correlated with all cytokines investigated (r = 0.150–0.548), except TNF-α. Lactate negatively correlated with pro-inflammatory cytokines like IL-1β (r = −0.324). Aging affected caecal histomorphology, bacterial activity and genes responsible for barrier integrity and inflammatory response. This effect could be attributed to the interaction between gut microbiota and immune system as well as the direct effect of metabolites on gut histomorphology and cytokine mRNA abundance.

description: The merger of two spiral galaxies is believed to be one of the main channels for the production of elliptical and early-type galaxies. In the process, the system becomes an (ultra) luminous infrared galaxy, or (U)LIRG, that morphs to a quasar, to a K+A galaxy, and finally to an early-type galaxy. The time scales for this metamorphosis are only loosely constrained by observations. In particular, the K+A phase should follow immediately after the QSO phase during which the dust and gas remaining from the (U)LIRG phase are expelled by the AGN. An intermediate class of QSOs with K+A spectral signatures, the post-starburst QSOs or PSQ, may represent the transitional phase between QSOs and K+As. We have compiled a sample of 72 {bona fide} $z<0.5$ PSQ from the SDSS DR7 QSO catalogue. We find the intermediate age populations in this sample to be on average significantly weaker and metal poorer than their putative descendants, the K+A galaxies. The typical spectral energy distribution of PSQ is well fitted by three components: starlight; an obscured power-law; and a hot dust component required to reproduce the mid-IR fluxes. From the slope and bolometric luminosity of the power-law component we estimate typical masses and accretion rates of the AGN, but we find little evidence of powerful radio-loud or strong X-ray emitters in our sample. This may indicate that the power-law component originates in a nuclear starburst rather than in an AGN, as expected if the bulk of their young stars are still being formed, or that the AGN is still heavily enshrouded in dust and gas. We find that both alternatives are problematic and that more and better optical, X-ray, and mm-wave observations are needed to elucidate the evolutionary history of PSQ.

Analysis of A-to-I RNA Editing in Schizophrenia Risk Gene MIR137
Creators: name: Pudukodu, Harish
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Schizophrenia is a complex psychiatric disorder that likely emerges as a result of interacting genetic and environmental risk factors. A prominent hypothesis for the etiology of schizophrenia is that schizophrenia emerges as a result of pre- and/or perinatal viral infection-induced inflammation in genetically predisposed individuals. This gene-environment interaction may be mediated by genetic regulators such as microRNA 137 (miR137), a regulatory RNA with a set of related SNPs that is highly associated with schizophrenia, and epigenetic phenomena such as RNA editing, which has been previously associated with schizophrenia and infection. Here I interrogate this gene-environment interaction by quantifying RNA editing of miR137, assessing the functional impact of this editing, and predicting its effects on schizophrenia risk in conjunction with a risk SNP. High-throughput RNA sequencing coupled to the PrimerID methodology revealed that miR137 is edited at a statistically significant level (p < 0.05) in both fetal human brain and adult mouse brain. Site-directed mutagenesis and luciferase assays demonstrated that A-to-I modification of certain pertinent bases in miR137 impart a large decrease in affinity to a target sequence. Finally, mathematical modeling and simulations based on empirical findings suggest that this RNA editing and a MIR137 schizophrenia-risk SNP significantly modulate inflammation-based schizophrenia risk burden (p < 2 x 10-16). These findings demonstrate that infection, the MIR137 gene, and RNA editing likely interact to promote schizophrenia risk, and thus this study serves to elucidate the cooperative influences of genetic and environmental risk factors on schizophrenia.

description: We argue that the COVID-19 virus has been a trigger for emerging practices of care by being an actor with agency that transforms the everyday life of subjects by placing them under uncertainty. Therefore, this paper aims to show how practices of care emerged or were maintained as vulnerable groups were confronted by restrictions to movement and uncertainties following the outbreak of COVID-19. We demonstrate this using two case studies of the Maasai pastoral community in Narok, Kenya and the community kitchens in the city of Berlin, Germany. Thus, we seek to show how practices of care for, care about, and care with are carried out by the members of these communities during pandemic times. Granted that care remains highly contentious in feminist literature, this paper contributes to a growing body of literature on care in Feminist Political Ecology by broadening the conceptualization of care. The research builds on a typology of care relations based on practices of distribution, exchange, and reciprocity. This allows us to show when care is exercised in a unidirectional and hierarchical way and when in a multidirectional way reinforcing social bonds of responsibility and collective care that transcends the socio-nature boundaries.

description: We derive the low-energy limit of quantum chromodynamics (QCD) and provide evidence that in the 't Hooft limit, i.e. for a very large number of colors and increasing 't Hooft coupling, quark confinement is recovered. The low energy limit of the theory turns out to be a non-local Nambu-Jona-Lasinio (NJL) model. The effect of non-locality, arising from a gluon propagator that fits quite well to the profile of an instanton liquid, is to produce a phase transition from a chiral condensate to an instanton liquid, as the coupling increases with lower momentum. This phase transition suffices to move the poles of the quark propagator to the complex plane. As a consequence, free quarks are no longer physical states in the spectrum of the theory.

description: The current status of Mach's principle is discussed within the context of general relativity. The inertial properties of a particle are determined by its mass and spin, since these characterize the irreducible unitary representations of the inhomogeneous Lorentz group. The origin of the inertia of mass and intrinsic spin are discussed and the inertia of intrinsic spin is studied via the coupling of intrinsic spin with rotation. The implications of spin-rotation coupling and the possibility of history dependence and nonlocality in relativistic physics are briefly mentioned.

description: We find that the duality between color and kinematics can be used to inform the high energy behavior of effective field theories. Namely, we demonstrate that the massless gauge theory of Yang-Mills deformed by a higher-derivative $F^3$ operator cannot be tree-level color-dual while consistently factorizing without a tower of additional four-point counterterms with rigidly fixed Wilson coefficients that reaches to the ultraviolet (UV). We find through explicit calculation a suggestive resummation, namely that their amplitudes are consistent with the $α'$ expansion of those generated by the $(DF)^2+\text{YM}$ theory, a known color-dual theory where the $F^2$ term has been given a mass squared proportional to $1 / α'$. As a result, considering consistent double-copy construction as a physical principle implies that an $F^3$-based color-dual resolution of the UV divergence in $\mathcal{N}=4$ supergravity comes at the cost of field-theoretic locality. Similarly, when double-copying $F^3$ with itself, double-copy consistency lifts $R^3$ gravity to a family of gravity theories with an all-order tower of higher-derivative corrections, which includes the closed bosonic string as a standard adjoint-type double-copy.

description: Genome editing technology provides new possibilities for animal breeding and aid in understanding host-pathogen interactions. In poultry, retroviruses display one of the most difficult pathogens to control by conventional strategies such as vaccinations. Avian leukosis virus subgroup J (ALV-J) is an oncogenic, immunosuppressive retrovirus that causes myeloid leukosis and other tumors in chickens. Severe economic losses caused by ALV-J remain an unsolved problem in many parts of the world due to inefficient eradication strategies and lack of effective vaccines. ALV-J attachment and entry are mediated through the specific receptor, chicken Na+/H+ exchanger type 1 (chNHE1). The non-conserved amino acid tryptophan 38 (W38) in chNHE1 is crucial for virus entry, making it a favorable target for the introduction of disease resistance. In this study, we obtained ALV-J-resistance in a commercial chicken line by precise deletion of chNHE1 W38, utilizing the CRISPR/Cas9-system in combination with homology directed repair. The genetic modification completely protected cells from infection with a subgroup J retrovirus. W38 deletion did neither have a negative effect on the development nor on the general health condition of the gene edited chickens. Overall, the generation of ALV-J-resistant birds by precise gene editing demonstrates the immense potential of this approach as an alternative disease control strategy in poultry.

 Habitat: bromeliad tanks (Alcantarea nahoumii); T 27.5 (± 2.8 ºC). pH 6.0 (± 0.5). C 0.24 (± 0.16 mS. cm-1). TDS 0.13 (± 0.10 ppt). DO 7.8 (± 4.2 mg.L- 1).
 Notes: In a previous study (Ramos et al. 2011), this taxon was identified as two distinct species: M. furcata C.Agardh ex Ralfs (1848: 73) and M. crux-melitensis Ralfs (1848: 73). When we reevaluated the material examined by Ramos et al. (2011), together with new collections from the area, we were able to identify those taxa as Micrasterias radians. That desmid showed the highest degree of polymorphism in all taxa studied, often presenting anomalous forms. The phenotypic plasticity of that species generated forms very similar to taxa such as M. furcata C.Agardh ex Ralfs (1848: 73) (with elongated lateral lobes) and M. crux-melitensis Ralfs (1848: 73) (with short lateral lobes). Another variable feature was the base of the polar lobe, which ranged from straight to intumescent, and the shape of the apex: slightly curved or straight.
 Authors such as Neustupa et al. (2010) and Coesel & Van Geest (2014) have discussed taxonomic problems in the Micrasterias radians complex, noting frequent confusion with the taxa mentioned above. Among the varieties of M. radians reported by those authors, the ones that are closest to the morphotypes from the Brazilian phytotelmata are M. radians var. radians and M. radians var. brasiliense (Grönblad) Willi Krieger & A.M.Scott. However, since their variation can be very wide, including with the presence of semicells with intermediary characteristics (in addition to other varieties of M. radians), we considered it better to identify all of the variation as belonging to a single taxon: Micrasterias radians. We therefore recommend further studies, preferably using a polyphase approach, to evaluate whether the phenotypic diversity of the Micrasterias radians complex occurring in bromeliads from Serra da Jiboia corresponds to the phenotypic expression of a single species or to different taxa.

description: We studied the interplay between the mass reach for electroweakinos at future hadron colliders and direct detection experiments. The lack of new phenomena at the LCH motivates us to focus on split supersymmetry scenarios with different electroweakino spectra. A 100 TeV hadron collider may reach masses up to 3 TeV in models of anomaly mediation with long-lived thermal Winos. Moreover, in scenarios where the lightest neutralino is not the only dark matter component, the interplay between collider searches and direct detection experiments might cover large part of the parameter space.

description: Children with developmental disabilities who have complex communication needs (CCN) frequently need to use augmentative and alternative communication (AAC) to communicate effectively and efficiently. Speech–language pathologists (SLPs) often work closely with parents and other professionals when deciding on the best AAC system to introduce to these children. This study aimed to describe the use of AAC by children with CCN in Malaysia as reported by their parents. An online survey distributed for this study was completed by 235 parents. Most of the parents of children with CCN who participated in this study reported that their children used low-tech AAC systems. A majority of respondents were satisfied with their child’s AAC system. Parental satisfaction was positively associated with the frequency of use and whether the use of AAC helped parents understand the child better. Challenges reported by parents when using AAC and the reason some families abandoned the use of AAC were similar. Examples of challenges include parents having limited time and the child lacking the motivation to use the AAC system. The findings of this study suggest the importance of SLPs actively involving parents in the selection of their children’s AAC system so they are agreeable with the system introduced and continuously supporting children and their families to encourage and sustain the use of AAC. Implications for rehabilitationSpeech–language pathologists (SLPs) can create communication opportunities for the child to use augmentative and alternative communication (AAC) and experience success, teach parents how to incorporate AAC into the family’s daily routine and activities, and reduce the demands on parents by preparing the AAC materials and programming the AAC system where possible.SLPs can provide ongoing support to school teachers to equip them with the necessary knowledge and skills to support the use of AAC in the classroom.

description: GEOSCALER: GEOMETRY AND RENDERING-AWARE DOWNSAMPLING OF 3D MESH TEXTURES: High-resolution texture maps are necessary to accurately represent real-world objects with 3D meshes. The large sizes of textures can bottleneck the real-time rendering of high-quality virtual 3D scenes on devices that have low computational budgets and limited memory. Downsampling the texture maps directly addresses the issue, albeit at the cost of visual fidelity. Traditionally, downsampling of texture maps is performed using methods such as bicubic interpolation and the Lanczos algorithm. These methods ignore the geometric layout of the mesh and its UV parameterization and also do not account for the rendering process used to obtain the final visualization that the users will experience. Towards filling these gaps, we introduce GeoScaler, which is a method of downsampling texture maps of 3D meshes while incorporating geometric cues and maximizing the visual fidelity of the rendered views of the textured meshes. We show that the textures generated by GeoScaler deliver significantly better quality rendered images compared to those generated by traditional downsampling methods.
A Cold, Hard Look: Focus Group Analysis of the ALS Ice Bucket Challenge

description: The ALS Ice Bucket Challenge was a social media craze that took over social media in the summer of 2014. It was vastly successful movement, raising over $100 million for ALS organizations and spreading awareness about Amyotrophic Lateral Sclerosis, a progressive neurodegenerative disease of the brain and spinal cord. The reasons for the campaign’s success are very intriguing, and might offer practical knowledge for communication strategists looking to use social networking sites to spread messages and gather support.
  Through focus group sessions conducted at UNC-Chapel Hill, this study attempted to understand the movement in relation to college students. The study sought to discover college student’s general opinions towards the campaign, to learn what reasons motivated participation (or non-participation) in the challenge, and ideas about what factors contributed to the campaign’s virality. Results indicated that the social nature of the campaign gave way for not only its success, but also its primary critiques. Future research might consider how social activism online is changing the function of social networking sites and could have impacts on the types of users that remain online.

Neuroscientists have recently started to investigate this by looking into how our brains process information concerning our reputation. Just a few years ago, it was discovered that when we learn that other people think highly of us, a key part of the brain’s reward system is activated [1]. The reward system is a set of interconnected brain structures that gives us a pleasurable feeling when we obtain or do things with a positive value. Getting a compliment feels good, so it makes sense that the reward system might be involved.

description: Integrated optical quantum memories are a scalable solution to synchronize a large number of quantum nodes. Without compact quantum memories, some astonishing quantum applications such as distributed quantum computing and quantum sensor networks would not be possible. Rather than find a specific material that meets all the requirements of an on-chip quantum memory as other protocols usually do, we propose to assign the memory requirements on coherent storage and controllability to rare earth ions and a lithium niobate crystal, respectively. Specifically, optical quantum states are stored in an erbium-doped lithium niobate micro-cavity by utilizing the electro-optic effect of lithium niobate. The cavity frequency can be shifted by an external electric field, thus modifying the resonance condition between the cavity and the collective atomic excitation. This effect is further used to suppress or enhance the emission of photon echoes. Our calculated results show that high efficiency and low noise performance is achievable.

description: The emergence of complex macroscopic phenomena from a small set of parameters and microscopic concepts demonstrates the power and beauty of physical theories. A theory which relates the wealth of data and peculiarities found in nuclei to the small number of parameters and symmetries of quantum chromodynamics is by that standard of exceptional beauty. Decade-long research on computational physics and on effective field theories facilitate the assessment of the presumption that quark masses and strong and electromagnetic coupling constants suffice to parameterize the nuclear chart. By presenting the current status of that enterprise, this article touches the methodology of predicting nuclei by simulating the constituting quarks and gluons and the development of effective field theories as appropriate representations of the fundamental theory. While the nuclear spectra and electromagnetic responses analyzed computationally so far with lattice QCD are in close resemblance to those which intrigued experimentalists a century ago, they also test the theoretical understanding which was unavailable to guide the nuclear pioneers but developed since then. This understanding is shown to be deficient in terms of correlations amongst nuclear observables and their sensitivity to fundamental parameters. By reviewing the transition from one effective field theory to another, from QCD to pionful chiral theories to pionless and eventually to cluster theories, we identify some of those deficiencies and conceptual problems awaiting a solution before QCD can be identified as the high-energy theory from which the nuclear landscape emerges.

 Material examined: BRAZIL, Bahia, Santa Teresinha, Serra da Jiboia. 14-I-2015, G. J. P. Ramos et al. s/n (HUEFS 224657), 18-VII-2015, G. J. P. Ramos et al. s/n (HUEFS 224672), 11-IX-2015, G. J. P. Ramos et al. s/n (HUEFS 224697), 20-XI-2015, G. J. P. Ramos et al. s/n (HUEFS 224718).
 Habitat: bromeliad tanks (Alcantarea nahoumii); T 27.4 (± 2.8 ºC). pH 5.9 (± 0.4). C 0.23 (± 0.16 mS. cm-1). TDS 0.13 (± 0.11 ppt). DO 8.3 (± 4.4 mg.L- 1).
 Notes, Netrium digitus was the desmid most parasitized by chytrid fungi in bromeliads at Serra da Jiboia, with 2–4 zoosporangia commonly found inside the cell. This pattern was also recorded in specimens from Holland (Coesel & Meesters 2007), which suggests that this relationship may be specific and more widely distributed than previously thought.
 Netrium digitus was one of the most predominant desmids, showing large populations in some bromeliads, often forming floating masses visible to the naked eye in bromeliad tanks. This is the first record of genus Netrium in a phytotelmata habitat.

description: Disfluencies are a commonly reported speech symptom associated with Parkinson disease (PD), though the cause remains unknown. Studies have consistently reported that people with PD experience more disfluencies, particularly atypical disfluencies compared to healthy controls. One proposed theory, known as the dualistic model of dopamine levels and stuttering, posits that abnormally high or low levels of dopamine may cause an increase in disfluencies. The aim of the current study is to examine how levodopa medication and deep-brain stimulation affect fluency in people with PD. Twenty-seven participants with PD underwent testing before (on and off medicine) and six months after deep-brain stimulator implant surgery (optimally medicated, on and off stimulation). Participants read a passage aloud and provided a 2-minute monologue. Speech samples were transcribed. The number of typical and atypical disfluencies were identified auditorily and using a wide-band spectrogram. After surgery, most participants reduced their levodopa equivalency dose from pre-implant levels. Results demonstrated no significant differences in frequency of disfluencies across time (pre-surgery, post-surgery) or condition (on/off medication/stimulation). Overall, participants produced more typical than atypical disfluencies and more disfluencies in the monologue task than the reading task. Results do not support the dualistic model of dopamine, but instead support a more nuanced and individualized role for dopamine in speech fluency. For example, patterns within individual subjects suggest changes in dopamine may play a role in speech fluency for individual patients with PD. Data support the effect of cognition and language formulation in the production of disfluencies, particularly typical disfluencies.

description: We examine entanglement of thermal states for spin-12 dimers in external magnetic fields. Entanglement transition in the temperature-magnetic field plane demonstrates a duality in spin-spin interactions. This identifies dual categories of symmetric and anti-symmetric dimers with each category classified into toric entanglement classes. The entanglement transition line is preserved from each toric entanglement class to its dual toric class. The toric classification is an indication of topological nature of the entanglement.

description: We study a discrete-time Markov process on triangular arrays of matrices of size $d\geq 1$, driven by inverse Wishart random matrices. The components of the right edge evolve as multiplicative random walks on positive definite matrices with one-sided interactions and can be viewed as a $d$-dimensional generalisation of log-gamma polymer partition functions. We establish intertwining relations to prove that, for suitable initial configurations of the triangular process, the bottom edge has an autonomous Markovian evolution with an explicit transition kernel. We then show that, for a special singular initial configuration, the fixed-time law of the bottom edge is a matrix Whittaker measure, which we define. To achieve this, we perform a Laplace approximation that requires solving a constrained minimisation problem for certain energy functions of matrix arguments on directed graphs.

description: Speech super-resolution (SR) is a task to increase speech sampling rate by generating high-frequency components. Existing speech SR methods are trained in constrained experimental settings, such as a fixed upsampling ratio. These strong constraints can potentially lead to poor generalization ability in mismatched real-world cases. In this paper, we propose a neural vocoder based speech super-resolution method (NVSR) that can handle a variety of input resolution and upsampling ratios. NVSR consists of a mel-bandwidth extension module, a neural vocoder module, and a post-processing module. Our proposed system achieves state-of-the-art results on the VCTK multi-speaker benchmark. On 44.1 kHz target resolution, NVSR outperforms WSRGlow and Nu-wave by 8% and 37% respectively on log spectral distance and achieves a significantly better perceptual quality. We also demonstrate that prior knowledge in the pre-trained vocoder is crucial for speech SR by performing mel-bandwidth extension with a simple replication-padding method.

description: There are contextual sets of multiple qubits whose commutation is parametrized thanks to the coset geometry $\mathcal{G}$ of a subgroup $H$ of the two-generator free group $G=\left\langle x,y\right\rangle$. One defines geometric contextuality from the discrepancy between the commutativity of cosets on $\mathcal{G}$ and that of quantum observables.It is shown in this paper that Kleinian subgroups $K=\left\langle f,g\right\rangle$ that are non-compact, arithmetic, and generated by two elliptic isometries $f$ and $g$ (the Martin-Maclachlan classification), are appropriate contextuality filters. Standard contextual geometries such as some thin generalized polygons (starting with Mermin's $3 \times 3$ grid) belong to this frame. The Bianchi groups $PSL(2,O\_d)$, $d \in \{1,3\}$ defined over the imaginary quadratic field $O\_d=\mathbb{Q}(\sqrt{-d})$ play a special role.
Developing a Refined Palate: Investigating the Role of the Nectin-Afadin Pathway in Mammalian Palatogenesis

description: Cleft palate (CP) forms as a result of the palatal shelves failing to fuse and is one of the most common birth defects worldwide. Human genetic studies have demonstrated that CP is heritable and frequently linked to monoallelic alterations. Previous studies done in isolated human populations have identified mutations in the cell adhesion molecule NECTIN-1 in cases of both syndromic and non-syndromic cleft palate. Furthermore, its family member NECTIN-4 has been found to be mutated in patients with ectodermal dysplasia, which often co-manifests with CP in several human syndromes. Collectively, these studies imply a crucial role for the nectin family of cell adhesion molecules in proper palate formation. Formation of the hard palate is well conserved between mice and humans, making the mouse a powerful tool to study the developmental genetics of secondary palatogenesis. While germline knockout mouse models of Nectin-1, -2, and -3 exist, they do not exhibit the clefting phenotypes observed in humans, presenting a significant challenge to understanding the role of this pathway. Utilizing an RNAi-based in utero lentiviral gene expression editing technique, we have generated mice deficient in nectin-1, which present with partially-penetrant CP. We have also generated a novel model of nectin-4 loss, which similarly presents with CP. Furthermore, combined loss of both nectin-1 and nectin-4 results in higher penetrance of CP, suggesting a clear role for both nectins in palate closure. Finally, depletion of the actin-binding protein afadin (Afdn), which acts downstream of nectin receptors, presents with a similar penetrance of CP as combined loss of nectin-1 and nectin-4. At the cellular level, loss of one or more nectins results in diminished and/or improper localization of canonical adherens junction (AJ) components, suggesting a critical and evolutionarily-conserved role for the nectin-afadin axis in palate closure, possibly due to altered cell-cell adhesion in the oral epithelium.

description: The global attitude synchronization problem is studied for networked rigid bodies under directed topologies. To avoid the asynchronous pitfall where only vector parts converge to some identical value but scalar parts do not, multiplicative quaternion errors are leveraged to develop attitude synchronization protocols for rigid bodies with the absolute measurements. It is shown that global synchronization of networked rigid bodies can be achieved if and only if the directed topology is quasi-strongly connected. Simultaneously, a novel double-energy-function analysis method, equipped with an ordering permutation technique about scalar parts and a coordinate transformation mechanism, is constructed for the quaternion behavior analysis of networked rigid bodies. In particular, global synchronization is achieved with our analysis method regardless of the highly nonlinear and strongly coupling problems resulting from multiplicative quaternion errors, which seriously hinder the traditional analysis of global synchronization for networked rigid bodies. Simulations for networked spacecraft are presented to show the global synchronization performances under different directed topologies.
