    Abstract Experimental data for the unimolecular decomposition of CS2 from the literature are analyzed by unimolecular rate theory with the goal of obtaining rate constants for the reverse reaction S + CS (+M) → CS2 (+M) over wide temperature and pressure ranges. The results constitute an important input for the kinetic modeling of CS2 oxidation. CS2 dissociation proceeds as a spin-forbidden process whose detailed properties are still not well understood. The role of the singlet-triplet transition involved is discussed.

    Abstract Locally invasive thymic neoplasms are challenging clinical scenarios and typically require a multidisciplinary approach. The involvement of major mediastinal veins such as the superior vena cava (SVC) used to be a contraindication to surgery, but with improved surgical technique and outcomes, this paradigm has shifted. In some situations, complex resections and reconstructions may be indicated and required to improve the long-term outcome of these patients. We report two of our cases along with a current review of literature. We also describe the preoperative workup, operative techniques, postoperative management, complications, and outcomes of patients with invasive thymic neoplasms that involve the mediastinal veins. Our first case describes a patient who was diagnosed with a thymoma extending from the diaphragm to the base of the neck that was also encasing major vascular structures including the SVC and left innominate vein. Our second case describes a patient who was also diagnosed with a large anterior mediastinal mass encasing the great veins and invading the chest wall. We describe the management of these patients and then delve deeper into operative techniques including SVC resection and reconstruction. We describe the types of conduits that can be used and complications to be mindful of when clamping the great veins, such as the SVC. Improvements in conduit materials and neoadjuvant and adjuvant therapies over the years have made it more feasible for patients with invasive thymic neoplasms to undergo surgery.

    Abstract Classifying specimens is a critical component of ecological research, biodiversity monitoring and conservation. However, manual classification can be prohibitively time-consuming and expensive, limiting how much data a project can afford to process. Computer vision, a form of machine learning, can help overcome these problems by rapidly, automatically and accurately classifying images of specimens. Given the diversity of animal species and contexts in which images are captured, there is no universal classifier for all species and use cases. As such, ecologists often need to train their own models. While numerous software programs exist to support this process, ecologists need a fundamental understanding of how computer vision works to select appropriate model workflows based on their specific use case, data types, computing resources and desired performance capabilities. Ecologists may also face characteristic quirks of ecological datasets, such as long-tail distributions, 'unknown' species, similarity between species and polymorphism within species, which impact the efficacy of computer vision. Despite growing interest in computer vision for ecology, there are few resources available to help ecologists face the challenges they are likely to encounter. Here, we present a gentle introduction for species classification using computer vision. In this manuscript and associated GitHub repository, we demonstrate how to prepare training data, basic model training procedures, and methods for model evaluation and selection. Throughout, we explore specific considerations ecologists should make when training classification models, such as data domains, feature extractors and class imbalances. With these basics, ecologists can adjust their workflows to achieve research goals and/or account for uncertainty in downstream analysis. Our goal is to provide guidance for ecologists for getting started in or improving their use of machine learning for visual classification tasks.

    Abstract Increasing use of paediatric long-term ventilation (LTV) has been reported around the world over the last two decades and it is anticipated that use of this medical intervention will continue to grow. Research has shown that children who use LTV have risk factors for feeding and swallowing difficulties which result in long-term reliance on non-oral feeding methods. This Patient and Public Involvement (PPI) activity explored experiences of parents of children with LTV on their children's feeding and swallowing journeys. Individual and group interviews with seven parents were conducted. Interview data was then analysed using content analysis. Families discussed a range of themes including impacts on their family, facilitators and barriers to feeding and swallowing journeys, speech and language therapy (SLT) support, their family's healthcare journey in relation to quality of life and future directions for research. This study highlighted potential key areas to explore when identifying ways to improve SLT care and research in feeding and swallowing for children who use LTV.

    Abstract We present a novel method for analysing socio-spatial segregation in cities by considering constraints imposed by transportation networks. Using a multilayered network approach, we model the interaction probabilities of socio-economic groups with random walks and Lévy flights. This method allows for evaluation of new transport infrastructure's impact on segregation while quantifying each network's contribution to interaction opportunities. The proposed random walk segregation index measures the probability of individuals encountering diverse social groups based on their available means of transit via random walks. The index incorporates temporal constraints in urban mobility with a parameter,

    Abstract The evolutionary history of vertebrates is replete with emergence of novel brain morphologies, including the origin of the human brain. Existing model organisms and toolkits for investigating drivers of neuroanatomical innovations have largely proceeded on mammals. As such, a compelling non-mammalian model system would facilitate our understanding of how unique brain morphologies evolve across vertebrates. Here, we present the domestic chicken breed, white crested Polish chickens, as an avian model for investigating how novel brain morphologies originate. Most notably, these crested chickens exhibit cerebral herniation from anterodorsal displacement of the telencephalon, which results in a prominent protuberance on the dorsal aspect of the skull. We use a high-density geometric morphometric approach on cephalic endocasts to characterize their brain morphology. Compared with standard white Leghorn chickens (WLCs) and modern avian diversity, the results demonstrate that crested chickens possess a highly variable and unique overall brain configuration. Proportional sizes of neuroanatomical regions are within the observed range of extant birds sampled in this study, but Polish chickens differ from WLCs in possessing a relatively larger cerebrum and smaller cerebellum and medulla. Given their accessibility, phylogenetic proximity, and unique neuroanatomy, we propose that crested breeds, combined with standard chickens, form a promising comparative system for investigating the emergence of novel brain morphologies.
