Competitiveness and sustainability: can ‘smart city regionalism’ square the circle?

Increasingly, the widely established, globalisation-driven agenda of economic competitiveness meets a growing concern with sustainability. Yet, the practical and conceptual co-existence—or fusion—of these two agendas is not always easy. This includes finding and operationalising the ‘right’ scale of governance, an important question for the pursuit of the distinctly transscalar nature of these two policy fields. ‘New regionalism’ has increasingly been discussed as a pragmatic way of tackling the variable spatialities associated with these policy fields and their changing articulation. This paper introduces ‘smart (new) city-regionalism’, derived from the principles of smart growth and new regionalism, as a policy-shaping mechanism and analytical framework. It brings together the rationales, agreed principles and legitimacies of publicly negotiated polity with collaborative, network-based and policy-driven spatiality. The notion of ‘smartness’, as suggested here as central feature, goes beyond the implicit meaning of ‘smart’ as in ‘smart growth’. When introduced in the later 1990s the term embraced a focus on planning and transport. Since then, the adjective ‘smart’ has become used ever more widely, advocating innovativeness, participation, collaboration and co-ordination. The resulting ‘smart city regionalism’ is circumscribed by the interface between the sectorality and territoriality of policy-making processes. Using the examples of Vancouver and Seattle, the paper looks at the effects of the resulting specific local conditions on adopting ‘smartness’ in the scalar positioning of policy-making

Guiding-center dynamics of vortex dipoles in Bose-Einstein condensates

A quantized vortex dipole is the simplest vortex molecule, comprising two counter-circulating vortex lines in a superfluid. Although vortex dipoles are endemic in two-dimensional superfluids, the precise details of their dynamics have remained largely unexplored. We present here several striking observations of vortex dipoles in dilute-gas Bose-Einstein condensates, and develop a vortex-particle model that generates vortex line trajectories that are in good agreement with the experimental data. Interestingly, these diverse trajectories exhibit essentially identical quasi-periodic behavior, in which the vortex lines undergo stable epicyclic orbits.Comment: 4 pages, 2 figure

Enhancing e-Infrastructures with Advanced Technical Computing: Parallel MATLAB® on the Grid

MATLAB® is widely used within the engineering and scientific fields as the language and environment for technical computing, while collaborative Grid computing on e-Infrastructures is used by scientific communities to deliver a faster time to solution. MATLAB allows users to express parallelism in their applications, and then execute code on multiprocessor environments such as large-scale e-Infrastructures. This paper demonstrates the integration of MATLAB and Grid technology with a representative implementation that uses gLite middleware to run parallel programs. Experimental results highlight the increases in productivity and performance that users obtain with MATLAB parallel computing on Grids

Dispensability of Escherichia coli's latent pathways

Gene-knockout experiments on single-cell organisms have established that expression of a substantial fraction of genes is not needed for optimal growth. This problem acquired a new dimension with the recent discovery that environmental and genetic perturbations of the bacterium Escherichia coli are followed by the temporary activation of a large number of latent metabolic pathways, which suggests the hypothesis that temporarily activated reactions impact growth and hence facilitate adaptation in the presence of perturbations. Here we test this hypothesis computationally and find, surprisingly, that the availability of latent pathways consistently offers no growth advantage, and tends in fact to inhibit growth after genetic perturbations. This is shown to be true even for latent pathways with a known function in alternate conditions, thus extending the significance of this adverse effect beyond apparently nonessential genes. These findings raise the possibility that latent pathway activation is in fact derivative of another, potentially suboptimal, adaptive response

Chairside fabricated fiber-reinforced composite fixed partial denture

The advances in the materials and techniques for adhesive dentistry have allowed the development of non-invasive or minimally invasive approaches for replacing a missing tooth in those clinical situations when conservation of adjacent teeth is needed. Good mechanical and cosmetic/aesthetic properties of fiber-reinforced composite (FRC), with good bonding properties with composite resin cement and veneering composite are needed in FRC devices. Some recent studies have shown that adhesives of composite resins and luting cements allow diffusion of the adhesives to the FRC framework of the bridges. By this so-called interdiffusion bonding is formed [1]. FRC bridges can be made in dental laboratories or chairside. This article describes a clinical case of chairside (directly) made FRC Bridge, which was used according to the principles of minimal invasive approach. Treatment was performed by Professor Vallittu from the University of Turku, Finland

Model Regulations for the Control of Land Subdivision

Viewed in this framework of the changing needs of land use controls, this article will endeavor to show how subdivision regulations can be successfully utilized to accomplish a community\u27s goals and objectives. Our purpose will be to indicate the problems concerning subdivision regulations in Missouri and to suggest various solutions based on existing legislation. This article will also present proposals for statutory revision, analysis of judicial decisions, and lastly, the provisions of a set of model subdivision regulations. The model covers all possible situations with which a governing body or administrative agency may be faced and incorporates requirements suited to meet each community\u27s respective needs. There are many areas of Missouri law in this field which require clarification. New concepts such as money-in-lieu of land, excess facilities, and compulsory dedications will have to be accorded judicial scrutiny and clarification. The model regulations have, however, been drafted in a form suited for immediate adoption by municipalities and counties

Mapping interactions with the chaperone network reveals factors that protect against tau aggregation.

A network of molecular chaperones is known to bind proteins ('clients') and balance their folding, function and turnover. However, it is often unclear which chaperones are critical for selective recognition of individual clients. It is also not clear why these key chaperones might fail in protein-aggregation diseases. Here, we utilized human microtubule-associated protein tau (MAPT or tau) as a model client to survey interactions between ~30 purified chaperones and ~20 disease-associated tau variants (~600 combinations). From this large-scale analysis, we identified human DnaJA2 as an unexpected, but potent, inhibitor of tau aggregation. DnaJA2 levels were correlated with tau pathology in human brains, supporting the idea that it is an important regulator of tau homeostasis. Of note, we found that some disease-associated tau variants were relatively immune to interactions with chaperones, suggesting a model in which avoiding physical recognition by chaperone networks may contribute to disease

Disappearing Data at the U.S. Federal Government

Health data hosted by the U.S. federal government have been disappearing. According to our analysis, between January 21 and February 11, 2025, the Centers for Disease Control and Prevention (CDC) removed 203 datasets (13% of its online datasets, a reduction from 1519 to 1316). The situation is dynamic; various datasets have been removed, restored, manipulated, or not posted as planned

Economic Development and Public Transit: Making the Most of the Washington Growth Management Act

Rapid and unplanned urban growth in the urbanizing and rural fringe areas of the United States has led to numerous problems for state, local, and regional governments. In particular, six crises are readily identifiable, each of which threatens to undermine quality of life and local competitive economic advantage. These crises include the following: (1) deterioration of central cities, first-ring suburbs, and closer-in neighborhoods, resulting in depopulation and abandonment of housing and the employment base; (2) spiraling suburban sprawl, creating massive infrastructure as well as energy costs; (3) loss of prime agricultural lands; (4) environmental crises and threats to open space, air and water quality, environmentally sensitive lands, and natural resources; (5) transportation congestion and resultant loss of quality of life; and (6) inflating cost of housing and its effect on affordable housing. These problems do not lend themselves to facile solutions or quick fixes; they must be addressed through the development and application of comprehensive state and regional growth management plans. This Article explores the history and development of growth management and delineates how growth management planning for the Washington Puget Sound region can be effectively implemented to provide a comprehensive system for attaining environmental and transit objectives
