Using the combat swimmer's stroke, Navy SEALs go for miles in grueling training events that push their physical and mental strength.
Hala Alyan's 'Salt Houses' is a family saga, although even the word 'saga' may be overly grand, since none of its characters are the makers of history: They are history’s victims.
How does a company, like United Airlines, recover from a public failure? In an article from 2006, Embracing Change as Opportunity, Richard Belluzzo outlines four key principles that are still relevant to the situation United finds itself in today. The first principle is a tough...

Play dead if a bear starts nosing around. Use moss on trees to find "north." Heard these tips? Careful —they're not always true.
With iconic architecture, a flourishing Michelin star-worthy food scene and a vermouth revival under way, there's never been a better time to check out the Catalan capital
Abstract: The present invention is a system and method for aircraft ground collision avoidance (iGCAS) comprising a modular array of software, including a sense own state module configured to gather data to compute trajectory, a sense terrain module including a digital terrain map (DTM) and map manger routine to store and retrieve terrain elevations, a predict collision threat module configured to generate an elevation profile corresponding to the terrain under the trajectory computed by said sense...

Abstract: According to one embodiment, a cross-correlator comprises a plurality of analog front ends (AFEs), a cross-correlation circuit and a data serializer. Each of the AFEs comprises a variable gain amplifier (VGA) and a corresponding analog-to-digital converter (ADC) in which the VGA receives and modifies a unique analog signal associates with a measured analog radio frequency (RF) signal and the ADC produces digital data associated with the modified analog signal. Communicatively coupled to... Читать дальше...
Abstract: A conditionally active limit regulator may be used to regulate the performance of engines or other limit regulated systems. A computing system may determine whether a variable to be limited is within a predetermined range of a limit value as a first condition. The computing system may also determine whether a current rate of increase or decrease of the variable to be limited is great enough that the variable will reach the limit within a predetermined period of time with no other changes...

Abstract: Described herein is a new holographic polymer dispersed liquid crystal (HPDLC) medium with broadband reflective properties, and a new technique for fabrication of broadband HPDLC mediums. The new technique involves dynamic variation of the holography setup during HPDLC formation, enabling the broadening of the HPDLC medium's wavelength response. Dynamic variation of the holography setup may include the rotation and/or translation of one or more motorized stages, allowing for time and spatial,...
Abstract: Na+-SAPO-34 sorbents were ion-exchanged with several individual metal cations for CO2 absorption at different temperatures (273-348 K) and pressures (

Abstract: The development and function of living tissues depends largely on interactions between cells that can vary in both time and space; however, temporal control of cell-cell interaction is experimentally challenging. By employing a micromachined silicon substrate with moving parts, herein is disclosed the dynamic regulation of cell-cell interactions via direct manipulation of adherent cells with micron-scale precision. The inventive devices and methods allow mechanical control of both tissue... Читать дальше...
Abstract: Systems and methods in accordance with embodiments of the invention fabricate objects including metallic glass-based materials using ultrasonic welding. In one embodiment, a method of fabricating an object that includes a metallic glass-based material includes: ultrasonically welding at least one ribbon to a surface; where at least one ribbon that is ultrasonically welded to a surface has a thickness of less than approximately 150.mu.m; and where at least one ribbon that is ultrasonically...

Sculpture to go on display at Queen's University in Kingston in September
When the Nixon administration fell into a chasm of disgrace, many felt that not only the Republican Party had been tarnished, but the presidency itself. Yet, the "ship of state" remained on an even keel. Can America still govern itself effectively? Hear from John W. Dean, Hendrik Hertzberg, and John Podhoretz. This program is part of the Shades of Red and Blue series, presented by The Ethics Centre, and co-sponsored by the Carnegie Council for Ethics in International Affairs and Bard Globalization and International Affairs program.
