In this study, ultrafast transient absorption spectroscopy (TAS) is utilized to examine the excited-state dynamics in methylammonium lead iodide/bromide (MAPb(I1-xBrx)3) perovskites as a function of bromide content. TAS spectral behavior reveals characteristic lifetimes for thermalization, recombination, and charge carrier injection of MAPb(I1-xBrx)3 from x = 0 to 0.3 infiltrated in mesoporous ...

This paper presents a performance analysis of wireless ad-hoc networks, with IEEE 802.11 as the underlying Wireless LAN technology. WLAN has, due to the fair radio resource sharing at the MAC-layer, the tendency to share the capacity equally amongst the active nodes, irrespective of their loads. An inherent drawback of this sharing policy is that a node that serves as a relay-node for multiple ...

Receiver-driven layered multicast has been designed to support scalable multimedia applications and very recently used to support bulk file transfers. Layered multicast congestion control assumes that all the receivers behind a bottleneck are equally able to subscribe to a particular number of cumulative layers. This paper explores the requirement placed on heterogeneous receivers behind a bott...

As a resource allocation strategy, plant growth and defense responses are generally mutually antagonistic. Brassinosteroid (BR) regulates many aspects of plant development and stress responses, however, genetic evidence of its integrated effects on plant growth and stress tolerance is lacking. We overexpressed the Arabidopsis BR biosynthetic gene AtDWF4 in the oilseed plant Brassica napus and s...

Most recent models conceptualize working memory (WM) as a continuous resource, divided up according to task demands. When an increasing number of items need to be remembered, each item receives a smaller chunk of the memory resource. These models predict that the allocation of attention to high-priority WM items during the retention interval should be a zero-sum game: improvements in rememberin...

Widely deployed multimedia services are expected to accommodate clients in a highly heterogeneous environment. Clients of a multimedia service may vary greatly in processing and communication capabilities. In addition, due to workload, location, and time of service differences, the availability of end-to-end resources between a client and a multimedia server may also vary possibly with a differ...

Binocular rivalry (BR) is an intriguing phenomenon that occurs when two different images are presented, one to each eye, resulting in alternation or rivalry between the percepts. The phenomenon has been studied for nearly 200 years, with renewed and intensive investigation over recent decades. The rate of perceptual switching has long been known to vary widely between individuals but to be rela...

The comprehensive systems-biology database (CSB.DB) was used to reveal brassinosteroid (BR)-related genes from expression profiles based on co-response analyses. Genes exhibiting simultaneous changes in transcript levels are candidates of common transcriptional regulation. Combining numerous different experiments in data matrices allows ruling out outliers and conditional changes of transcript ...

The production resource management is an important activity to acquire competitive advantage, which is concerned about how to integrate equipment with the aim of meeting the demand and reaching lower price of final products. This paper presents a typical issue, which is the fact that extra capacities of bottleneck equipment result in oversizing and thus idleness of it. Moreover, it will form a ...

This paper presents NomLex-BR, a lexical resource describing Brazilian Portuguese nominalizations, and its integration with OpenWordnet-PT. We first describe the original English NOMLEX lexical resource and how we used it to bootstrap a Portuguese version. Subsequently, we describe how this lexicon can be embedded into OpenWordnet-PT, which facilitates its use and helps spot-checking both the b...
