On the Sequence of Pedal Triangles

open access: yes, 1983
Although geometers have studied the properties of triangles for over two thousand years, there still remain problems of interest involving operations performed infinitely often. A given triangle T_0 generates a sequence of triangles T_n where T_(n+1) is the pedal triangle of T_n.

Using 3DF Zephyr to determine body‐worn camera position

open access: yesJournal of Forensic Sciences, Volume 71, Issue 3, Page 1466-1472, May 2026.
Abstract Photogrammetry has been used consistently in forensic settings to document crime scenes three‐dimensionally. Traditionally, a large number of still photos are taken, and information from those photos is used to create a three‐dimensional (3D) model.

A comparison of results from two simulators used for studies of astronaut maneuvering units [PDF]

open access: yes
A comparison of the results from a fixed-base, six-degree-of -freedom simulator and a moving-base, three-degree-of-freedom simulator was made for a close-in, EVA-type maneuvering task in which visual cues of a target spacecraft were used for guidance ...

Scope as a Source for Non‐Incremental Effects?

open access: yesLanguage and Linguistics Compass, Volume 20, Issue 3, May/June 2026.
ABSTRACT Incrementality is one of the hallmarks of realtime language comprehension. It contrasts sharply with another feature of language comprehension, the high degree of context dependence exhibited by many expressions calling for global adaptations to the larger discourse context.

Insights Into Symmetry and Substitution Patterns Governing Singlet–Triplet Energy Gap in the Chemical Space of Azaphenalenes

open access: yesChemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

Preclinical circulating tumor DNA shedding duration and prognostic implications of modeling 3669 patients with cancer in the American Cancer Society Cancer Prevention Study‐3 and Circulating Cell‐Free Genome Atlas Substudy 3

open access: yesCancer, Volume 132, Issue 8, 15 April 2026.
Abstract Introduction Previous studies have estimated the mean sojourn and dwell times within stages for commonly screened cancer types. However, little is known about the preclinical detection window of circulating tumor DNA (ctDNA) (ie, ctDNA positivity), which is important for understanding multicancer early detection.

A study of helicopter stability and control including blade dynamics [PDF]

open access: yes
A linearized model of rotorcraft dynamics has been developed through the use of symbolic automatic equation generating techniques. The dynamic model has been formulated in a unique way such that it can be used to analyze a variety of rotor/body coupling ...

Self‐Assembly of Anti‐Inflammatory Peptide Amphiphiles for Mucosal Health

open access: yesChemBioChem, Volume 27, Issue 7, 14 April 2026.
Self‐assembled peptide amphiphiles with mucosal surface targeting capabilities represent a novel strategy to promote human mucosal tissue health through enhanced delivery of anti‐inflammatory and antiviral peptides at mucosal sites. Broad spectrum anti‐inflammatory peptide amphiphiles (AIF‐PAs) have been developed as an innovative strategy for the ...
