Abstract Background Bone metastases are a common cause of skeletal morbidity in patients with advanced cancer. The pattern of skeletal morbidity is complex, and the number of skeletal complications...
Gravitational Space Dilation (2009)
We point out that, if one accepts the view that the standard second on an atomic clock is dilated at low gravitational potential (ordinary gravitational time dilation), then the standard meter must...
Risk Factors for Hip Fracture in Older Home Care Clients (2009)
Stolee, Paul, Poss, Jeff, Cook, Richard J., Byrne, Kerry, Hirdes, John P.
Background Little information is available on hip fracture risks among community-dwelling persons receiving home care. Our aim was to identify risk factors for hip fracture from health information...
Second-order estimating equations for the analysis of clustered current status data (2009)
Cook, Richard J., Tolusso, David
With clustered event time data, interest most often lies in marginal features such as quantiles or probabilities from the marginal event time distribution or covariate effects on marginal hazard...
FALL-RELATED HIP FRACTURES (2009)
Stolee, Paul, Poss, Jeff, Cook, Richard J., Byrne, Kerry, Hirdes, John P.
There is a set of first-order differential equations for the curvature tensor in general relativity (the curvature equations or CEs for short) that are strikingly similar to the Maxwell equations of...
Interpretation of the Cosmological Metric (2008)
Cook, Richard J., Burns, M. Shane
The cosmological Robertson-Walker metric of general relativity is often said to have the consequences that (1) the recessional velocity $v$ of a galaxy at proper distance $\ell$ obeys the Hubble law...
Regression analysis of multivariate panel count data (2008)
He, Xin, Tong, Xingwei, Sun, Jianguo, Cook, Richard J.
We consider panel count data which are frequently obtained in prospective studies involving recurrent events that are only detected and recorded at periodic assessment times. The data take the form...
Brown, Janet E., Cook, Richard J., Major, Pierre, Lipton, Allan, Saad, Fred, Smith, Matthew, ...
Background: Whether bone markers have prognostic value in patients with bone metastases is unknown. We investigated this question in patients with bone metastases secondary to prostate cancer and to...
Tests for multivariate recurrent events in the presence of a terminal event (2004)
Chen, Bingshu Eric, Cook, Richard J.
In studies involving diseases associated with high rates of mortality, trials are frequently conducted to evaluate the effects of therapeutic interventions on recurrent event processes terminated by...
Cumulative processes related to event histories (2003)
Cook, Richard J., Lawless, Jerald F., Lee, Ker-Ai
Costs or benefits which accumulate for individuals over time are of interest in many life history processes. Familiar examples include costs of health care for persons with chronic medical...
Cumulative processes related to event histories (2003)
Cook, Richard J., Lawless, Jerald F., Lee, Ker-Ai
Costs or benefits which accumulate for individuals over time are of interest in many life history processes. Familiar examples include costs of health care for persons with chronic medical...
The design of clinical trials is typically based on marginal comparisons of a primary response under two or more treatments. The considerable gains in efficiency afforded by models conditional on one...
Intermittent Atomic Fluorescence, (2002)
Kimble,H. J., Cook,Richard J., Wells,Ann L.
In a single atom double resonance experiment involving a strong and a weak transition, quantum jumps on the weak transition cause the resonance fluorescence of the strong transition to turn on and...
A generalized mover-stayer model for panel data (2002)
Cook, Richard J., Kalbfleisch, John D., Yi, Grace Y.
A generalized mover–stayer model is described for conditionally Markov processes under panel observation. Marginally the model represents a mixture of nested continuous‐time Markov processes...
Methodology for Treatment Evaluation in Patients With Cancer Metastatic to Bone (2001)
Cook, Richard J., Major, Pierre
Background: Patients with cancer metastatic to bone experience several adverse and clinically important skeletal-related events, including pathologic fractures, vertebral compressions with fracture,...

Monitoring surgical performance using risk-adjusted cumulative sum charts (2000)
Stefan H. Steiner, Richard J. Cook, Vern T. Farewell, Tom Treasure
The cumulative sum (CUSUM) procedure is a graphical method that has been used to monitor surgical outcomes, that "signals " if sufficient evidence has accumulated that there has...
Monitoring surgical performance using risk-adjusted cumulative sum charts (2000)
Steiner, Stefan H., Cook, Richard J., Farewell, Vern T., Treasure, Tom
The cumulative sum (CUSUM) procedure is a graphical method that is widely used for quality monitoring in industrial settings. More recently it has been used to monitor surgical outcomes whereby it...
Brumback, Babette A., Cook, Richard J., Ryan, Louise M.
Chorionic villus sampling (CVS) is a valued method of prenatal diagnosis that is often preferred over amniocentesis because it can be performed earlier, but which has also raised concern over a...
Monitoring Paired Binary Surgical Outcomes Using Cumulative Sum Charts (1999)
Stefan H. Steiner, Richard J. Cook, Vern T. Farewell
this article we focus on situations in which a process is being monitored and two correlated outcomes variables are used to characterize the response. The process in the motivating example is a...
El-Hewie, Mohamed F., Cook, Richard J.
For an arbitrary conducting surface Z(x,y) we obtained an analytical expression for the local refractive index nu as a function of Z, del Z/del x, del Z/del y, and the Drude conductivity sigma by...

Intermittent atomic fluorescence (1986)
Kimble, H. J., Cook, Richard J., Wells, Ann L.
In a single-atom double-resonance experiment involving a strong and a weak transition, quantum jumps on the weak transition cause the resonance fluorescence of the strong transition to turn on and...
Possibility of Direct Observation of Quantum Jumps (1985)
Cook, Richard J., Kimble, H. J.
In a single-atom double-resonance experiment involving a strong and a weak transition, quantum jumps on the weak transition cause the fluorescence of the strong transition to turn on and off...

Heparin-induced thrombocytopenia (HIT) is caused by platelet-activating IgG antibodies that recognize platelet factor 4 (PF4) bound to heparin. Immunogenicity of heparins differs in that...
Rinku Sutradhar, Richard J. Cook
A conditionally Markov multiplicative intensity model is described for the analysis of clustered progressive multistate processes under intermittent observation. The model is motivated by a long-term...
