This paper analyzes the training process of generative adversarial networks (GANs) via stochastic differential equations (SDEs). It first establishes SDE approximations for the training of GANs under stochastic gradient algorithms, with precise error bound analysis. It then describes the long-run behavior of GAN training via the invariant measures of its SDE approximations under proper conditions. This work builds a theoretical foundation for GAN training and provides analytical tools to study its evolution and stability.

This article considers the question of what constitutes item-based morphology, with a specific look at grammatical tone. Numerous case studies of grammatical tone are examined in light of the debate on whether morphology is item-based or process-based. In each case, tonal alternations are an exponent, sometimes the sole exponent, of some grammatical feature. Two of the case studies are examples of grammatical tone that can straightforwardly be analysed as involving concatenated morphophonological forms; however, in other cases, the grammatical tone cannot be reduced to the concatenation of a tonal affix or phonological feature with some stem. The latter type cannot straightforwardly be analysed as item-based, but if still phonologically predictable and productive, is not satisfactorily analysed as suppletive. This article suggests a set of diagnostics that can be used to determine whether a given phenomenon is best analysed as item-based, process-based or suppletive. Then, an analysis is presented in Cophonologies by Phase (CbP), where morphosyntactic features can be mapped not only to underlying phonological items, but also to morpheme-specific constraint weight adjustments. CbP allows for what may have been traditionally called item-based and process-based morphology to co-exist in a single framework.

Undergraduate research assistants (URAs) perform important roles in many political scientists’ research projects. They serve as coauthors, survey respondents, and data collectors. Despite these roles, there is relatively little discussion about how best to train and manage URAs who are working on a common task: content coding. Drawing on insights from psychology, text analysis, and business management, as well as my own experience in managing a team of nine URAs, this article argues that supervisors should train URAs by pushing them to engage with their own mistakes. Via a series of simulation exercises, I also argue that supervisors—especially supervisors of small teams—should be concerned about the effects of errant post-training coding on data quality. Therefore, I contend that supervisors should utilize computational tools to monitor URA reliability in real time. I provide researchers with a new R package, ura, and a web-based application to implement these suggestions.

The Black Sea is a substantial inland sea and has a very fascinating border on the east and west. It reaches into the Mediterranean through the straits, into Europe via rivers, and toward Asia via the Caucasus. The human relations developed through this network has led to the emergence of cultural landscape elements in the region. The natural landscape elements that have developed inherently in the natural beauty of the region have also become one of the most important pieces of heritage in the region. In this region, many uncontrolled practices that have taken place in recent years have rapidly degraded the cultural and natural landscape. The purpose of this study is to emphasize the beauty of nature, which makes the Eastern Black Sea region one of the most significant cultural and natural heritage areas of the world, and to explore its impact on human life in the context of water heritage as well as to address the dynamic risks of losing this beauty. In this study, the recognition of water as a heritage component is conceptually discussed in the context of the inherent cultural heritage and natural heritage. The unifying and integrative power of the multicultural water heritage that the region possesses is explicated.

The human gut microbiota can biosynthesize essential micronutrients such as B-vitamins and is also known for its metabolic cooperative behaviour. The present study characterises such B-vitamin biosynthesizers, their biosynthetic pathways, explores their prevalence and abundance, examines how lifestyle or diet affects them in multiple Indian cohorts and compares it with the Chinese cohort. To achieve this, publicly available faecal metagenome data of healthy individuals from multiple Indian (two urban and three tribal populations) and a Chinese cohort were analysed. The distribution of prevalence and abundance of B-vitamin biosynthesizers showed similar profiles to that of the entire gut community of the Indian cohort, and there were 28 B-vitamin biosynthesizers that had modest or higher prevalence and abundance. The omnivorous diet affected only the prevalence of a few B-vitamin biosynthesizers; however, lifestyle and/or location affected both prevalence and abundance. A comparison with the Chinese cohort showed that fourteen B-vitamin biosynthesizers were significantly more prevalent and abundant in Chinese as compared with Indian samples (False Discovery Rate (FDR) <= 0·05). The metabolic potential of the entire gut community for B-vitamin production showed that within India, the tribal cohort has a higher abundance of B-vitamin biosynthesis pathways as compared with two urban cohorts namely, Bhopal and Kasargod, and comparison with the Chinese cohort revealed a higher abundance in the latter group. Potential metabolic cooperative behaviour of the Indian gut microbiome for biosynthesis of the B-vitamins showed multiple pairs of species showed theoretical complementarity for complete biosynthetic pathways genes of thiamine, riboflavin, niacin and pantothenate.

In this article I apply Fineman’s vulnerability thesis to explore the ways in which vulnerability is constructed and mobilised in a criminal law context. Using a ‘failure-to-protect’ offence as a case study reveals contemporary constructs of vulnerability as both a problem to be solved and gendered. Constructing women as pathologically vulnerable allows the state and its institutions to downplay the situational vulnerability of women, evading responsibility for tackling VAWG. Responsibilising women to manage risks to children posed by male violence requires that women undertake ‘safety work’, rendering them vulnerable to both moral and legal sanction if not performed adequately. Replacing the autonomous subject with the relationally vulnerable subject generates new understandings of the ways entwining femininity and vulnerability shores up the (male-coded) autonomous legal subject. Moreover, reconceiving vulnerability as universal reveals the potential of the vulnerable subject for a more inclusive criminal subject who is both embedded and embodied.

This paper is concerned with the design and control of a tilt-rotor UAV (TRUAV), with the purpose of simplifying the mechanical structure and transition handling. Previous works on TRUAVs control consider a different controller for each flight mode. Furthermore, two sets of actuators are used: propellers in the VTOL mode, and aerodynamic surfaces in the fixed-wing mode. In this work, a new design that does not contain any control surfaces is proposed. A new control strategy is also presented to accommodate this particularity. Unlike previous works, this strategy uses a single controller to handle both flight phases, making the transition between the two phases no longer an issue. Furthermore, such a characteristic makes the drone capable of following any flight trajectory, which is vital for applications such as the tracking of a ground target. Simulations, conducted on the full nonlinear model of the famous Zagi flying wing drone, showed the effectiveness of the proposed control strategy in tracking a typical trajectory profile with a smooth transition from VTOL to fixed-wing mode.

Occasionalism is often seen as a peculiarity of early modern philosophy. The idea that God is the sole source of efficient causation in the world strikes many as at best implausible. It was, however, a natural inference based on the seventeenth-century view that the laws of nature are simply God's decrees. The question here is whether such a view and its more recent descendants entail occasionalism. I argue that they do not, but showing why involves a new take on what exactly the laws of nature do.

Abhilash Pillai's stage adaptation of Salman Rushdie's Midnight's Children (2005–6) introduced a new visual language to Indian theatre, conceiving performance between theatre and cinema. Pillai's work presents history as memory, amnesia and re-remembering within the framework of a multisensorial scenography that largely uses the vocabularies of the Bollywood film industry. The politics of the performance lies less in the thematic than in its optical dynamics, different as they are from both scene painting and the aestheticization of the public sphere. The production shows how theatre experience in a media society may primarily build on the perceptual, but without dismissing text or suspending the cognitive altogether. The visual media are used more as an intervention in politico-aesthetic discourse than as mere technology. As I explain the reasons for the long absence of any scholarly study of the production, I also consider its relevance to the current political scene in India.
