Separability and Aggregation [PDF]
Economica, 1990 This paper examines the conditions for homothetic separability of a technology that is an aggregate of technologies of individual firms or industries. Given that the primitive (industry or firm) technologies exhibit homothetic separability, the authors establish necessary and sufficient conditions for the aggregate (sectoral) technology to also exhibit

Computation-Aware Data Aggregation [PDF]
, 2019 Data aggregation is a fundamental primitive in distributed computing wherein a network computes a function of every nodes\u27 input. However, while compute time is non-negligible in modern systems, standard models of distributed computing do not take ...

Aggregating Causal Judgments [PDF]
Philosophy of Science, 2014 Decision making typically requires judgments about causal relations: we need to know the causal effects of our actions and the causal relevance of various environmental factors. We investigate how several individuals’ causal judgments can be aggregated into collective causal judgments.

Structure-based inhibitors of amyloid beta core suggest a common interface with tau. [PDF]
, 2019 Alzheimer's disease (AD) pathology is characterized by plaques of amyloid beta (Aβ) and neurofibrillary tangles of tau. Aβ aggregation is thought to occur at early stages of the disease, and ultimately gives way to the formation of tau tangles which ...

Neuroforecasting Aggregate Choice [PDF]
Current Directions in Psychological Science, 2018 Advances in brain-imaging design and analysis have allowed investigators to use neural activity to predict individual choice, while emerging Internet markets have opened up new opportunities for forecasting aggregate choice. Here, we review emerging research that bridges these levels of analysis by attempting to use group neural activity to forecast ...

Aggregation with Multiple Conservation Laws
, 1995 Aggregation processes with an arbitrary number of conserved quantities are investigated. On the mean-field level, an exact solution for the size distribution is obtained. The asymptotic form of this solution exhibits nontrivial ``double'' scaling.

Observing Convective Aggregation [PDF]
Surveys in Geophysics, 2017 Convective self-aggregation, the spontaneous organization of initially scattered convection into isolated convective clusters despite spatially homogeneous boundary conditions and forcing, was first recognized and studied in idealized numerical simulations.

Advanced Science, 2020 Hyperbranched polymers constructed from CO2 possess unique architectures and properties; however, they are difficult to prepare. In this work, CO2‐based, hyperbranched poly(alkynoate)s (hb‐PAs) with high molecular weights and degrees of branching are ...
