The development of excellent performance of Na-ion batteries remains great challenge owing to the poor stability and sluggish kinetics of cathode materials. Herein, B substituted Na3V2P3-x B x O12 (0 ≤ x ≤ 1) as stable cathode materials for Na-ion battery is presented. A combined experimental and theoretical investigations on Na3V2P3-x B x O12 (0 ≤ x ≤ 1) are undertaken to reveal the evolution ...

Looking at trends in private employer-based health insurance from 2003 to 2013, this issue brief finds that premiums for family coverage increased 73 percent over the past decade--faster than median family income. Employees' contributions to their premiums climbed by 93 percent over that time frame. At the same time, deductibles more than doubled in both large and small firms. Workers are thus ...

Brightness induction is the modulation of the perceived intensity of a region by the luminance of surrounding regions and reveals fundamental properties of neural organization in the visual system. Grating induction affords a unique opportunity to precisely measure the temporal properties of induction using a quadrature motion technique. Contrary to previous reports that induction is a sluggish...

We analyze the effect of an exogenous shock to the Italian mortgage market and we show that most households do not act rationally when it comes to take mortgage-refinancing decisions. Thanks to a new legislation passed in 2007, borrowers have been allowed to refinance their loans at no cost. This reform— along with the drop of interest rates occurred between 2008 and 2009—has produced a unique ...

A new quantum dynamic equation for excitation energy transfer is developed which can describe quantum coherent wavelike motion and incoherent hopping in a unified manner. The developed equation reduces to the conventional Redfield theory and Forster theory in their respective limits of validity. In the regime of coherent wavelike motion, the equation predicts several times longer lifetime of el...

George Janini is an economist in the Branch of Information and Analysis, Division of Consumer Expenditure Surveys, Bureau of Labor Statistics. GEORGE JANINI According to published reports by the Air Transport Association,1 the airline travel industry is looking to rebound from the September 11, 2001, (9/11) terrorist attacks. As reported, Americans were traveling in record numbers before 9/11 b...

Understanding the fundamental mechanisms behind the complex landscape of corporate mergers and acquisitions is of crucial importance to economies across the world. Adapting ideas from the fields of complexity and evolutionary dynamics to analyse business ecosystems, we show here that ancestry, i.e. the cumulative sum of historical mergers across all ancestors, is the key characteristic to compa...

Such perisaccadic mislocalization is maximal in the direction of the saccade and varies systematically with the target-saccade onset delay. We have recently shown that under head-fixed conditions perisaccadic errors do not follow the quantitative predictions of current visuomotor models that explain these mislocalizations in terms of spatial updating. These models all assume sluggish eye-moveme...

W today’s world economy plagued by recession and sluggish performance, China stands out with its sustained high growth, perhaps due to market-oriented economic reforms that began in 1978. The growth has been accompanied by an explosion in China’s household saving ratio, which has reached an impressive level in recent years, just when there has been a worldwide reduction in the private saving ra...

Measuring value and interest rate risk in retail financial markets such as the market for consumer deposits has proven to be a very difficult problem for financial firms. Standard models of value and interest rate risk (duration), based on the competitive market paradigm, are inappropriate in retail markets characterized by sluggish price and quantity behavior. Although the penetration of sophi...
