Isoelectric focusing separates proteins at the pH where their net charge is zero. Most failed runs trace to three things: conductivity in the sample, an endpoint measured in hours rather than volt-hours, and a reducing agent that leaves the basic end of the strip.
Expansion Microscopy: Choosing a Protocol and Proving the Expansion Was Isotropic
Expansion microscopy physically enlarges a fixed specimen inside a swellable hydrogel so a conventional confocal resolves nanoscale detail. The protocol choice matters less than measuring the local expansion factor and validating isotropy in the region you actually imaged.
Fluorescence Lifetime Imaging (FLIM): What Lifetime Measures That Intensity Cannot
FLIM measures how long fluorophores stay excited, not how many photons they emit — a readout that is largely concentration-independent. A practical guide to photon budgets, the pile-up limit most people quote wrong, IRF limits, phasor analysis and FLIM-FRET.
Research Methods & Statistics
Q Methodology: Q-Sorts, By-Person Factor Analysis, and Reading the Factor Arrays
Q methodology transposes the factor-analytic matrix so each person’s whole Q-sort becomes a variable. That inversion sets the loading threshold from the number of statements, not participants — and drives the Q-set, P-set, rotation and factor-retention decisions.
ANOVA in Python with statsmodels: anova_lm, Type III Contrasts, and the AnovaRM Limits
statsmodels will return a clean-looking F table for a model that answers a different question than you asked. The three failure points are a missing C(), anova_lm’s Type I default, and AnovaRM’s silent lack of a sphericity correction.
Choosing an Implementation Science Framework: Process, Determinant, or Evaluation
Implementation frameworks serve three different aims — guiding the process, explaining determinants, and evaluating success. A practical routing guide to process models, determinant frameworks and evaluation frameworks, and how to combine them without incoherence.

A working guide to Donabedian’s structure-process-outcome triad for QI teams: how to classify a candidate measure, why process measures produce signal long before outcomes do, how strong the causal chain is in published validation studies, and where balancing measures belong.
Shapiro-Wilk Test in R: shapiro.test(), Its Sample-Size Limits, and When Not to Use It
How to run shapiro.test() in R, why it stops at n = 5000, why W and n must be reported together, and why using the p-value to pick between a t-test and a rank test inflates conditional Type I error.
Wilcoxon Test in R: wilcox.test(), the W Statistic, and the Silent Exact/Approximate Switch
One R function runs both Wilcoxon tests, and three of its defaults routinely trip people up: the statistic it names W is not the one SPSS reports, it drops to the normal approximation without being asked, and its confidence interval does not estimate a difference in medians.
Mixed-Effects Models: Multilevel, Hierarchical, and What the Random Part Does
Mixed-effects, multilevel and hierarchical models are one model under three names. Clustered data break OLS standard errors, and the random structure you choose feeds back into fixed-effect inference.
