<strong>Species / Specimen:</strong> Helicobacter pylori</p>
<strong>Strain:</strong> 26695</p>
<strong>Tilt Series Settings:</strong>  Single Axis, tilt range: (-50.0°, 50.0°), step: 2°, constant angular increment, dosage: 130.0 eV/Å²,  defocus: -8.0 μm,  magnification: 19500x. </p>

<strong>Collaborators and Roles:</strong> I received these cells from Carrie Schaffer from the university of Kentucky. These are wild . type cells but they don't express complete FliP protein. Therefore, they don't assemble full . flagella. We knocked out FlgS protein of the flagellar motor to study the early assembly . states of flagellar motor.</p>
<strong>Purification / Growth Conditions / Treatment:</strong> I grew the cells on blood agar plates from -80 stock at 37C with 5% CO2. the cells were grown . for 48 hours and then spread on a new plate with a cotton swab and left to grow for 24 hours. . The grids were prepared from both batches (48 hours, and 24 hours, separately).</p>
<strong>Sample Preparation:</strong> The samples were prepared with Vitrobot IV. Blotting conditions were either: blot force 6, blot . time 3, drain time 1 OR blot force -3, blot time 4, drain time 1. 100% humidity. Cu grids. 10 nm . gold.</p>

title: Ipseity Daily Data

description: At what rate do individuals say they are X?

Begining on 2025-07-08, I surveyed a small random sample of American adults on a daily cadence.  They responded to many items of the form: Does <signifier> describe you today?

The file ipseity-daily-aggregated.csv in this repository contains the aggregated results through 2025-07-28.  The columns are as follows:



signifier - a word, phrase or emoji

yes_count - the number of respondents who answered yes (aggregated all-time).

no_count - the number of respondents who answered no (aggregated all-time).

prevalence_per_10k - an estimate of the prevalence per 10,000.  If we were to survey 10,000 American adults, how many would we expect to respond yes to this signifier?  The number is calculated as yes_count / (yes_count + no_count) * 10,000.

earliest_obs_date - this date represents the first time this particular signifier was ever displayed to a respondent.  Signifiers are chosen with stochasticity from a long list; new signifiers are sometimes added, old signifiers are sometimes deleted, and a signifier may be moved higher or lower in priority for sampling.

latest_obs_date - the date closest to the present date on which signifier was most recently presented to a respondent.
