    Holder exponent spectra for human gait

    Full text link
    The stride interval time series in normal human gait is not strictly constant, but fluctuates from step to step in a complex manner. More precisely, it has been shown that the control process for human gait is a fractal random phenomenon, that is, one with a long-term memory. Herein we study the Holder exponent spectra for the slow, normal and fast gaits of 10 young healthy men in both free and metronomically triggered conditions and establish that the stride interval time series is more complex than a monofractal phenomenon. A slightly multifractal and non-stationary time series under the three different gait conditions emerges.Comment: 23 pages, 12 figures, 9 Table

    Dollarizing The Cash Conversion Cycle

    For most companies to be financially successful, it is critically important that operating cash flows be effectively managed. The Cash Conversion Cycle (CCC) is a traditional tool that companies use to measure the average time required for operating cash flows to cycle from cash out for the payment of payables and back to cash flow in from the collection of receivables. Knowledge that the rate their operating cash flow is speeding up or slowing down, as indicated by a decreasing or increasing CCC, while useful information, is of limited value to the company. The CCC indicates nothing about the absolute dollar amount of the cash flow. This paper illustrates a method by which the current year actual CCC and the next year target CCC, along with a few other items of data, can be used to forecast the dollar amount of the next year’s operating cash flows. The extension of the CCC to enable it to help forecast the dollar amount of operating cash flows makes the CCC more useful to companies attempting to effectively manage operating cash flows

    Emergence of topological electronic phases in elemental lithium under pressure

    Full text link
    Lithium, a prototypical simple metal under ambient conditions, has a surprisingly rich phase diagram under pressure, taking up several structures with reduced symmetry, low coordination numbers, and even semiconducting character with increasing density. Using first-principles calculations, we demonstrate that some predicted high-pressure phases of elemental Li also host topological electronic structures. Beginning at 80 GPa and coincident with a transition to the Pbca phase, we find Li to be a Dirac nodal line semimetal. We further calculate that Li retains linearly-dispersive energy bands in subsequent predicted higher pressure phases, and that it exhibits a Lifshitz transition between two Cmca phases at 220 GPa. The Fd-3m phase at 500 GPa forms buckled honeycomb layers that give rise to a Dirac crossing 1 eV below the Fermi energy. The well-isolated topological nodes near the Fermi level in these phases result from increasing p-orbital character with density at the Fermi level, itself a consequence of rising 1s core wavefunction overlap, and a preference for nonsymmorphic symmetries in the crystal structures favored at these pressures. Our results provide evidence that under pressure, bulk 3D materials with light elements, or even pure elemental systems, can undergo topological phase transitions hosting nontrivial topological properties near the Fermi level with measurable consequences; and that, through pressure, we can access these novel phases in elemental lithium.Comment: 5 pages, 5 figures, accepted for publicatio
