In this work, we consider the problem of localizing multiple signal sources based on time-difference of arrival (TDOA) measurements. In the blind setting, in which the source signals are not known, the localization task is challenging due to the data association problem. That is, it is not known which of the TDOA measurements correspond to the same source. Herein, we propose to perform joint local
Adaptive radiation is a major source of biodiversity but the way in which known components of ecological opportunity, ecological differentiation, and reproductive isolation underpin such biodiversity patterns remains elusive. Much is known about the evolution of ecological differentiation and reproductive isolation during single speciation events, but exactly how those processes scale up to comple
In this Perspective, we discuss thermal imbalance and the associated electron-mediated thermal transport in quantum electronic devices at very low temperatures. We first present the theoretical approaches describing heat transport in nanoscale conductors at low temperatures, in which quantum confinement and interactions play an important role. We then discuss the experimental techniques for genera
In EU migration law scholarship, accounts of crisis and its relation to law flourished in relation to the migrant and refugee arrivals which took place in the in the period of 2015-2016. To offer new insight on the relation of crisis, EU law-making and migration, this chapter focuses on the same topic but from an entirely different angle and time frame. Specifically, this chapter does not look at
Environmental degradation is one of the most significant challenges faced by humanity, yet current global politics struggle to implement collective solutions. Previous research has suggested that the EU has a leadership role in the international climate change regime complex, which refer to a set of overlapping institutions that address different aspects of climate governance. Moreover, within the
Revegetation of the tailings dumps produced by various industrial activities is necessary to prevent dust storms and erosion and represents a great challenge for ecological restoration. Little is known about the microbial colonisation and community structure of revegetated tailings following site exploitation. Here, we report the sequencing of 16S rRNA and internal transcribed spacer (ITS) fungal
Exercise has many beneficial effects that provide health and metabolic benefits. Signaling molecules are released from organs and tissues in response to exercise stimuli and are widely termed exerkines, which exert influence on a multitude of intricate multi-tissue processes, such as muscle, adipose tissue, pancreas, liver, cardiovascular tissue, kidney, and bone. For the metabolic effect, exerkin
LINE-1 (L1) retrotransposons are a noted source of genetic diversity and disease in mammals. To expand its genomic footprint, L1 must mobilize in cells that will contribute their genetic material to subsequent generations. Heritable L1 insertions may therefore arise in germ cells and in pluripotent embryonic cells, prior to germline specification, yet the frequency and predominant developmental ti
E-scooter sharing has been commonly used to integrate public transport systems in many cities worldwide. Accurately modeling integration between shared e-scooters and public transport is important for multi-modal urban transportation development and management. However, the effects of catchment size are scarcely considered while modeling their integration by widely adopting the method based on the
Parkinson's disease (PD) is characterized by the loss of the dopaminergic nigrostriatal pathway which has led to the successful development of drug therapies that replace or stimulate this network pharmacologically. Although these drugs work well in the early stages of the disease, over time they produce side effects along with less consistent clinical benefits to the person with Parkinson's (PwP)
This chapter seeks to explore the intersections between occupational cultures, bystanders, and social justice and inclusion based on the empirical example of policing. Specifically, we pursue the question: what is the role of police officers as bystanders to occupational police culture and how does that influence inclusion? Against the backdrop of occupational culture, we put forth four key aspect
In this paper, we recall Lepowsky's and Wakimoto's product character formulas formulated in a new way by using arrays of specialized weighted crystals of negative roots for affine Lie algebras of type Cl(1), Dl+1(2) and A2l(2). Lepowsky–Wakimoto's infinite periodic products appear as one side of (conjectured) Rogers–Ramanujan-type combinatorial identities for affine Lie algebras of type Cl(1).
Values have been discussed both in relation to the normative character of Ecological Economics and, albeit implicitly, in conceptions of human beings. Nevertheless, a conceptualisation of individually-held values remains underdeveloped. Scholars who do engage on a conceptual level tend to focus on the values of nature in the context of ecosystem services, with less emphasis on: (a) more generally-
The European Union (EU) and the EU member states have adopted a number of policies that can support circular economy developments in the electrical and electronic equipment (EEE) sector, and additional policies have been proposed. The policies include the new Ecodesign Regulation and a new Battery Regulation, and forthcoming rules related to durability and repairability of mobile phones and tablet
Here we study the role of negative shifts in public opinion in the economic lives of under-represented racial groups by investigating sudden changes in views towards Asian people following the anti-Chinese rhetoric that emerged with the COVID-19 pandemic, and associated changes in employment status and earnings in the US labour market. Using data from the Current Population Survey, we find that, u
