Can artificial agents benefit from human conventions? Human societies manage to successfully self-organize and resolve the tragedy of commons in common-pool resources, spite bleak prediction non-cooperative game theory. On top that, real-world problems are inherently large-scale low observability. One key concept that facilitates coordination such settings is use conventions. Inspired by behavi...

Safeguarding crop pollination services requires the identification of pollinator species involved and provision their ecological requirements at multiple spatial scales. However, potential for agroecological intensification pollinator-dependent crops by harnessing diversity is limited our capacity to characterise community each crop, determine how it influenced different survey methods used, as...

Tree rings provide information about the climatic conditions during the growing season by recording them in different anatomical features, such as intra-annual density fluctuations (IADFs). IADFs are intra-annual changes of wood density appearing as latewood-like cells within earlywood, or earlywood-like cells within latewood. The occurrence of IADFs is dependent on the age and size of the tree...

General flowering (GF) is a unique phenomenon wherein, at irregular intervals, taxonomically diverse trees in Southeast Asian dipterocarp forests synchronize their reproduction at the community level. Triggers of GF, including drought and low minimum temperatures a few months previously has been limitedly observed across large regional scales due to lack of meteorological stations. Here, we aim...

Cost-efficient compressive sensing is challenging when facing large-scale data, i.e., data with large sizes. Conventional compressive sensing methods for large-scale data will suffer from low computational efficiency and massive memory storage. In this paper, we revisit well-known solvers called greedy algorithms, including Orthogonal Matching Pursuit (OMP), Subspace Pursuit (SP), Orthogonal Ma...

ontology is the main infrastructure of the semantic web which provides facilities for integration, searching and sharing of information on the web. development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. by emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...

Crater degradation on Mars is a key to understand erosion through time. Strongly eroded craters in the highlands are interpreted to be the result of enhanced erosion rate during the Noachian epoch [1]. While fluvial valleys climatic meaning and duration are still difficult to define (strongly warmer climate or episodic activity under slightly warmer climate), the enhanced Noachian craters degra...

the aim of this study was to evaluate the capability of the empirical (large scale) and fundamental (small scale) rheological tests to differentiate between wheat flours of different harvest years. in order to provide flours affected by different climatic conditions, harvest years 2004 and 2005 characterized by high temperatures and large amounts of rainfall were chosen. moreover, a control whe...
