Emergent Behavior of Living Neuronal Networks : Creating circuits and exploring the dynamics of neurons in vitro

In the past two decades there’s been an incredible development in the field of in vitro neural cultures. Thanks to the developments in embryonic stem cell technology, and the ability to produce pluripotent stem cells from adult human cells, producing human neural cultures has become much more widely accessible, and the ability to recreate physiological processes is increasing at an accelerating ra

Social Preferences and Environmental Externalities

Standard economic theory assumes that consumers ignore the externalities they create, such as emissions from burning fossil fuels and generating waste. In an incentivized study (N = 3, 718), we find that most people forgo substantial gains to avoid imposing negative externalities on others. Using administrative data on household waste, we show a clear link between such prosociality and waste behav

Current problems and future directions of transfusion-induced alloimmunization : summary of an NHLBI working group

In April 2010, a working group sponsored by the National Heart, Lung, and Blood Institute was assembled to identify research strategies to improve our understanding of alloimmunization caused by the transfusion of allogeneic blood components and to evaluate potential approaches to both reduce its occurrence and manage its effects. Significant sequelae of alloimmunization were discussed and identif

Identifying intrinsic drivers to changes in riparian ecosystem services by using PSR framework : A case study of the Grand Canal in Jiangsu, China

The interaction between water and land greatly affected the change of the riparian ecosystem service value (ESV) under the background of rapid regional development. In order to analyze the change of ESV, this study combined the Logarithmic Mean Divisia Index (LMDI) and the P (pressure)-S (state)-R (response) framework to exploring its driving factors based on the ESV accounting method improved by

Research on Evolutionary Game Analysis of Spatial Cooperation for Social Governance of Basin Water Pollution

Given that the two institutional arrangements of government regulation and market allocation cannot effectively solve the conflict between individual and collective interests in the process of water pollution control, this work presents a useful attempt on the third institutional arrangement of environmental governance—social governance—to overcome the dilemma. Based on common pool resource theory

Evaluation of the Effectiveness of Water Ecological Restoration Based on the Relationship between the Supply and Demand of Ecological Products—A Case Study of the Yellow River Delta

The imbalance between the supply and demand of ecological products between society and ecosystems is an important cause of a series of water ecological problems, and water ecological restoration projects aim to improve the above supply–demand relationship by means of inputs from the social side. For this reason, this paper takes the Yellow River Delta region as an example to launch a study on the

'Missing Girls' and Reproductive Justice @Beijing+30

This piece considers how we can think critically around prenatal sex selection and the problem of ‘missing girls’ and devise strategies to address this phenomenon without risk of harming the rights and interests of girls and women. To address the problem of ‘missing girls’ our research findings suggest there is a need to move beyond a rights-based approach towards gender and reproductive justice,

Articles on Random Normal Matrix Theory

In this thesis, we investigate the random normal matrix model in which the eigenvalues correspond to the two-dimensional Coulomb gas at inverse temperature β = 2. The thesis consists of seven papers concerning differentaspects of the random normal matrix model. The main topics of the thesis are asymptotics of the correlationkernel, fluctuations of linear statistics, asymptotics of the partition fu

Physiological Characterisation of Nitrogen Fixing Bacteria in Pure and Mixed Cultures

The scope of this Master Thesis project is divided in two parts. In the first part, the objective is to characterise various strains of Azotobacter vinelandii under diazotrophic conditions with regards to growth rate and production of metabolites, such as ammonium or PHB. This will allow for an assessment on which nitrogen fixing strain displays the most promising results for use in the second par

Children and YouTubers : Navigating the maze of sponsored content and advertising for merch

Recent scholarly attention has focused on YouTubers' advertising practices and their influence on young followers' understanding of commercial content. Although previous studies primarily explore children's advertising literacy, they often treat YouTubers' influencer marketing as a unified phenomenon. This article distinguishes between two types of advertising: sponsored content and merchandise (m

Digital literacies among infants and toddlers : Everyday engagement of digital media in the home environment

For many children, their home is where they first encounter digital media technologies. The aim of this study is to investigate how children 0 – 3 years old engage in digital media. We address digital literacies as a sociocultural mindset and a toolbox with attention to skills and comprehensions as well as how children express their agency. The overall research question is: What skills, comprehens

Development of Optically Communicating Nanowire-based III-V Devices : Optical broadcasting for artificial neural networks

Denna avhandling presenterar utvecklingen och studiet av en flexibel och kiselchip-kompatibel integration av III–V nanotrådsbaserade (NW) optoelektroniska komponenter i nätverkskretsar, där kommunikation sker genom utsändning av ljussignaler. Detta innefattar en undersökning av hur neurala bearbetningsbeteenden kan efterliknas med hjälp av fotoniska kretsar på chip. Både experimentella resultat soThis thesis presents the development and study of a flexible and Silicon-chip compatible integration of III–V nanowire (NW) optoelectronic components in network circuits, where communication is done via the broadcasting of light signals. This includes an investigation into how neural processing behaviours can be emulated using on-chip photonic circuits. Both experimental works that demonstrate the
