The COVID-19 pandemic quickly led to an abundance of publications and recommendations, despite a paucity information on how affects children with cancer. This created dire need for trusted resource curated space the pediatric oncology community share experiences. Global Observatory Resource Center Childhood Cancer was developed, launched, maintained by International Society Pediatric Oncology S...

Background Space use by animals is determined by the interplay between movement and the environment, and is thus mediated by habitat selection, biotic interactions and intrinsic factors of moving individuals. These processes ultimately determine home range size, but their relative contributions and dynamic nature remain less explored. We investigated the role of habitat selection, movement unre...

We study the optimal harvesting of a renewable resource that cannot be continuously exploited, i.e. after the harvest the released space cannot be immediately reallocated to the resource. In the meantime, this space can be given an alternative use of positive utility. We consider a discrete time model over an infinite horizon with discounting, and characterize the optimality of two myopic polic...

Distributed systems such as Grid- and Cloud Computing provision web services to their users in all of the world. One of the most important concerns which service providers encounter is to handle total cost of ownership (TCO). The large part of TCO is related to power consumption due to inefficient resource management. Task scheduling module as a key component can has drastic impact on both user...

The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

This paper examines the interaction of spatial and dynamic aspects of resource extraction from forests by local people. Highly cyclical and varied across both space and time, the patterns of resource extraction resulting from the spatial-temporal model bear little resemblance to the patterns drawn from focusing either on spatial or temporal aspects of extraction, as is typical in both the model...

In the single rent-to-buy decision problem, without a priori knowledge of the amount of time a resource will be used we need to decide when to buy the resource, given that we can rent the resource for $1 per unit time or buy it once and for all for $c. In this paper we study algorithms that make a sequence of single rent-to-buy decisions, using the assumption that the resource use times are ind...

This paper examines a number of theoretical and practical issues concerning the use of decision-theoretic planning to implement agents in market-based systems. The markets considered here result from the decomposition of complex, intra-organizationai resource allocation problems such as manufacturing scheduling. Although these problems can be formulated as monolithic optimization problems, they...

In some substructural logics, the memory used by proofs is treated as a first-class multiplicative resource, but the choices made by those proofs are not. Since we can convert between space and time complexity, these “resource conscious” logics are therefore not actually guaranteed to preserve memory—for example, linear logic allows the erasure and duplication of natural numbers with time compl...

In 2003, Hofmann and Jost introduced a type system that uses a potentialbased amortized analysis to infer bounds on the resource consumption of (first-order) functional programs. This analysis has been successfully applied to many standard algorithms but is limited to bounds that are linear in the length of the input. Here we extend this system to polynomial resource bounds. An automatic amorti...
