Fabrication of diamond structures by self-assembly is a fundamental challenge in making three-dimensional photonic crystals. We simulate a system of model hard particles with attractive patches and show that they can self-assemble into a diamond structure from an initially disordered state. We quantify the extent to which the formation of the diamond structure can be facilitated by "seeding" th...

In the 1990s numerous winter orographic cloud seeding experiments were conducted over Utah’s Wasatch Plateau. Several previously published case studies successfully documented the physical response in clouds and precipitation to ground-based seeding with silver iodide and liquid propane. A previously unpublished case study that shows additional evidence of positive seeding effects is presented ...

in order to study the effect of sowing methods and seeding rates on fodder yield and some agronomic characters of nikshahri alfalfa ecotype, an experiment was conducted in a split plot arrangement in randomized complete block design with four replications in the field of agricultural and natural resources center of baluchistan in iranshahr region. in this study, sowing methods: hand spread, 12 ...

introduction: meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. it can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. as a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. trauma and viruses are possible e...

Four cloud-seeding cases over southern Idaho during the 2010/11 winter season have been simulated by the WeatherResearch and Forecasting (WRF)model using the coupled silver iodide (AgI) cloud-seeding scheme that was described in Part I. The seeding effects of both ground-based and airborne seeding as well as the impacts of model physics, seeding rates, location, timing, and cloud properties on ...

In this paper we propose a class of propagation models for multiple competing products over a social network. We consider two propagation mechanisms: social conversion and self conversion, corresponding, respectively, to endogenous and exogenous factors. A novel concept, the product-conversion graph, is proposed to characterize the interplay among competing products. According to the chronologi...

This paper provides nested sets and vector representations of knockout tournaments. The paper introduces classification of probability domain assumptions and a new set of axioms. Two new seeding methods are proposed: equal gap seeding and increasing competitive intensity seeding. Under different probability domain assumptions, several axiomatic justifications are obtained for equal gap seeding....
