Asymptotic analysis for radial sign-changing solutions of the Brezis-Nirenberg problem [PDF]
, 2013 We study the asymptotic behavior, as $lambda ightarrow 0$, of least energy radial sign-changing solutions $u_lambda$, of the Brezis--Nirenberg problem $$-Delta u = lambda u + |u|^{2^* -2}u quad hbox{in} B_1$$ $$u=0 quad hbox{on} partial B_1 ...

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific
Sustainable Development, EarlyView.ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.

Self‐Assembled hBN Wrinkles as Planar Optofluidic Channels
Small, EarlyView.Thermally induced wrinkling creates nanochannel networks in hexagonal boron nitride flakes without lithography. Channel dimensions depend on flake thickness and substrate. Liquid infiltration into the networks and fluorescence localization of DNA along the channels highlight their potential as a scalable, optically addressable planar nanofluidic ...

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures
Structural Concrete, EarlyView.Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

Wildlife Biology, EarlyView.Balancing moose Alces alces populations with forest production objectives remains a major challenge in Swedish forestry. We developed a mechanistic, data‐driven model of browse availability in Scots pine Pinus sylvestris saplings by linking shoot‐level allometry, crown architecture, and tree height development.

Nonlinear Neumann problems with indefinite potential and concave terms
, 2015 In this paper we conduct a detailed study of Neumann problems driven by a nonhomogeneous differential operator plus an indefinite potential and with concave contribution in the reaction.

Semi-classical bound states of Schrödinger equations [PDF]
, 2014 We study the existence of semi-classical bound states of the nonlinear Schrödinger equation \begin{linenomath} -\varepsilon2\Delta u+V(x)u=f(u),\quad x\in {\bf R}^N,\end{linenomath} where N ≥ 3;, Ï is a positive parameter; V:R N → [0, ∞) satisfies some ...

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

International Journal of Urban and Regional Research, EarlyView.Abstract Much of the current popular and academic literature on the provision of green spaces is dominated by the assumption that ‘nature’ is an unalloyed positive, and that socioeconomic and racial exclusion from access to green spaces is a problem of unequal spatial distribution rather than of the form and content of particular urban designs.

The British Journal of Sociology, EarlyView.ABSTRACT This article develops a cultural and relational model of political polarisation that integrates insights from currently disconnected streams of scholarship to conceive polarisation as a discursive and performative struggle over sacred meanings.
