Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers
Advanced Science, EarlyView.Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

Advanced Science, EarlyView.A flexible pressure sensor with triple‐gradient design of conductivity, modulus, and dimension in binary micro‐dome pixels is proposed. Based on precisely‐designed CNT/PDMS matrix, the device exhibits a linear sensitivity of 974.1 kPa−1 across range up to 1.8 MPa (R2 > 0.99), offering an effective strategy for potential applications in healthcare ...

The Specific Gravity Adjustment in Urinalysis
Archives of Environmental Health: An International Journal, 1969Over twenty years’ experience with the specific gravity adjustment in urinalysis has been reviewed. It is concluded that this method of expressing results of analysis of urine for heavy metals, solvent metabolites, and radioactive isotopes is preferable to the unadjusted concentration.

Interpretation of Specific Gravity by Dipstick
Archives of Pediatrics & Adolescent Medicine, 1988Sir .—The widespread use of dipsticks such as the Ames N-Multistix-SG strip (Miles Laboratories, Elkhart, Ind) has some built-in problems as well as a form of medical laboratory absurdity. Comments have been made in the more general literature, but to date we have not read a comment in a pediatric journal.
