Contemporary pulsar timing experiments have reached a sensitivity level where systematic errors introduced by existing analysis procedures are limiting the achievable science. We have developed tempo2, a new pulsar timing package that contains propagation and other relevant effects implemented at the 1 ns level of precision (a factor of ∼ 100 more precise than previously obtainable). In contras...

Measuring the Timing Ability of Fixed Income Mutual Funds This paper evaluates the ability of bond funds to "market time" factors related to bond markets. Timing ability generates nonlinearity in fund returns, but there are several non-timing-related sources of nonlinearity. We find that controlling for non-timing-related nonlinearity is important. Funds' returns are more concave than benchmark...

This article presents the design of a new asynchronous early output full adder which when cascaded leads to a relative-timed ripple carry adder (RCA). The relative-timed RCA requires imposing a very small relative-timing assumption to overcome the problem of gate orphans associated with internal carry propagation. The relative-timing assumption is however independent of the RCA size. The primar...

In timing perception studies, the timing of one event is usually manipulated relative to another, and participants are asked to judge if the two events were synchronous, or to judge which of the two events occurred first. Responses are analyzed to determine a measure of central tendency, which is taken as an estimate of the timing at which the two events are perceptually synchronous. When these...

the purpose of the present study was to examine the effects of self – control modeling , that is presenting moded to learner whenever they asked for it, on learning a timing task.twenty four right handed subjects (12 males, 12 females, aged 19-20) voluntarily participated in the study and were assigned randomly to two groups of self – control and yoked.the task was pressing the keys number 1, 4...

The temporal pattern and relative timing of action potentials among neocortical neurons may carry important information. However, how cortical circuits detect or generate coherent activity remains unclear. Using paired recordings in rat neocortical slices, we found that the firing of fast-spiking cells can reflect the spiking pattern of single-axon pyramidal inputs. Moreover, this property allo...

This study investigated the influence of the presence and timing of cutaneous vibration cues supplied to the finger pad on the perception of slip of a contact surface slid beneath it. We designed an apparatus that made it possible to supply precisely controlled shear force, sliding displacement and vibration cues to the finger pad via a moving surface. We conducted an experiment to assess the e...

The verification of a n-stage pulse-driven IPCMOS pipeline, for any n > 0, is presented. The complexity of the system is 32n transistors and delay information is provided at the level of transistor. The correctness of the circuit highly depends on the timed behavior of its components and the environment. To verify the system, three techniques have been combined: (1) relative-timing-based verifi...
