Period-doubling bifurcation in nonlinear systems
, 1985 The dependence of the critical exponents, such as the Feigenbaum ratios, of the period-doubling bifurcation on the order of critical point z is studied. The dependence is quantitatively given for one-dimensional dissipative maps.

PERIOD DOUBLING BIFURCATION SET SEARCH BASED ON DRCOMPOSITION AND PSO
, 2022 This paper studies application of the PSO to the calculation of the period doubling bifurcation sets in a bifurcation neuron. The neuron is a simple neuron model that outputs spike-train by repeating integrate-and-fire behavior.

Clinical, Histologic, and Serological Predictors of Renal Function Loss in Lupus Nephritis
Arthritis Care &Research, EarlyView.Objective Kidney survival is the ultimate goal in lupus nephritis (LN) management, but long‐term predictors remain inadequately studied, requiring long‐term follow‐up. This study aimed to identify baseline and early longitudinal predictors of kidney survival in the Accelerating Medicines Partnership LN longitudinal cohort.

Stability and Robust Control of Period Doubling Bifurcations
, 1993 This thesis addresses the stability and feedback control of period doubling bifurcations. We find formulas for determining the stability of nondegenerate and degenerate period doubling bifurcations.

Arthritis Care &Research, EarlyView.Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Arthritis Care &Research, EarlyView.Objective This study aimed to describe real‐world trends in preconception and prenatal use of antirheumatic drugs among pregnant individuals with rheumatic diseases in Ontario, Canada. Methods We conducted a time‐series analysis using repeated cross‐sectional data to examine annual patterns of disease‐modifying antirheumatic drug (DMARD) use among ...

Period doubling in optical frequency combs
This thesis project explores period doubling in optical frequency combs, an area with limited prior research. An optical frequency comb can be used in telecommunications and high-precision metrologyand is a coherent set of discrete, equidistant frequency
