Gallup says 48 percent of Americans approve of Republican Trump's transition and 48 percent disapprove. At this time in 2008, 75 percent approved of Democrat Barack Obama's transition and only 17 percent disapproved. At a comparable point in January 2001, 65 percent of Americans approved of Republican George W. Bush's transition and 26 percent disapproved. In late 1992, 67 percent approved of Democrat Bill Clinton's transition and 15 percent disapproved.
While great strides have been made in collecting presence data and developing accurate species distribution models, much less is known about the migratory process that guides the spatio-temporal changes in distributions for migrating species, especially birds. In this work, we address a challenging inference task, where given only aggregate and noisy data of the volume of birds for each spatial pixel and time window, we predict the likely transition links with their associated probabilities. We propose a framework to build such migration networks for different bird species and present a real world example of constructing a network using our approach.
It is safe to say that even before the impact of the COVID-19 pandemic hit; companies had begun a steady march into the cloud. Then, with the events of this year, we have seen an incredible surge in demand for remote technical services and an overload of data compiling on application platforms. These increases are leading organizations of all sizes to seek larger, flexible, and secure platforms to support the rapid, immediate growth and propel their companies into the future. Earlier this summer, Gartner predicted public cloud services would grow 19 percent just this year, despite also acknowledging the impacts of COVID-19 would cause overall global IT spending to decline eight percent in 2020. With this rapid growth, companies making quick transitions to the cloud can overlook or miss key learnings and vital steps that can guarantee a successful cloud migration.
The neocortex exhibits a six-layered structure that is formed by radial migration of excitatory neurons, for which the multipolar-to-bipolar transition of immature migrating multipolar neurons is required. Here, we report that subplate neurons, one of the first neuron types born in the neocortex, manage the multipolar-to-bipolar transition of migrating neurons. By histochemical, imaging, and microarray analyses on the mouse embryonic cortex, we found that subplate neurons extend neurites toward the ventricular side of the subplate and form transient glutamatergic synapses on the multipolar neurons just below the subplate. NMDAR (N-methyl-d-aspartate receptor)–mediated synaptic transmission from subplate neurons to multipolar neurons induces the multipolar-to-bipolar transition, leading to a change in migration mode from slow multipolar migration to faster radial glial-guided locomotion. Our data suggested that transient synapses formed on early immature neurons regulate radial migration.
As the world evolves to deal with the changes fraught by the COVID-19 pandemic, the existing business operating models –from supply chains to distribution –are being redesigned to attain new levels of resilience, agility, productivity, and secure end-user reach. Underpinning this transition is cloud technology, that has become the key enabler in reshaping the business ecosystem.This is even more so in the recent years as it has evolved rapidly, becoming more reliable, scalable, and flexible over the past few years. While cloud-based solutions were already in play, pandemic-induced acceleration in adoption has brought over the fence sitters and the slow adopters. In fact, Forrester Research expects the global cloud computing market size to grow from USD 371.4 billion in 2020 to USD 832.1 billion by 2025, with the global public cloud infrastructure market estimated to grow by 35% to USD 120 billion in 2021. Migrating critical services from on-premises and collocated hardware to cloud enables organizations to manage their IT infrastructure remotely without having to deal with the challenges of security, hardware procurement, and software updates.
