Complete rectal prolapse presenting with colorectal cancer

open access: yesInnovative Surgical Sciences, 2023
Rectal prolapse is defined as prolapse of all layers of rectal wallout of the anal sphincter. The aim was to (i) describe the extremely rare combination of a rectal prolapse with colon cancer in an older female patient, (ii) comment on management ...

Study of the coincidences between the gravitational wave detectors EXPLORER and NAUTILUS in 2001 [PDF]

open access: yes, 2002
We report the result from a search for bursts of gravitational waves using data collected by the cryogenic resonant detectors EXPLORER and NAUTILUS during the year 2001, for a total measuring time of 90 days.

USE OF GAMMA–GAMMA COINCIDENCE TECHNIQUE IN INVESTIGATING GAMMA – RAYS ATTENUATION AT DIFFERENT ENERGIES

open access: yesTikrit Journal of Pure Science, 2023
A gamma–gamma fast –slow coincidence spectrometer composed of two 3"×3"NaI(Tl) detectors  and peripheral electronics is used in investigating some effects on the photo peak  after the penetration of gamma –rays from lead.

Coincidence analysis to search for inspiraling compact binaries using TAMA300 and LISM data [PDF]

open access: yes, 2003
Japanese laser interferometric gravitational wave detectors, TAMA300 and LISM, performed a coincident observation during 2001. We perform a coincidence analysis to search for inspiraling compact binaries.

Appearance of Chance Coincidence in Attenuation Measurements Carried out by using Coincidence Technique

open access: yesTikrit Journal of Pure Science, 2022
The appearance of chance coincidence in attenuation measurements using coincidence technique is investigated. A two 3"*3" NaI(Tl) detector coincidence spectrometer with 0.5 μ Ci Na-22 source were used.

Theory of photon coincidence statistics in photon-correlated beams [PDF]

open access: yes, 1999
The statistics of photon coincidence counting in photon-correlated beams is thoroughly investigated considering the effect of the finite coincidence resolving time. The correlated beams are assumed to be generated using parametric downconversion, and the

Obstruction theory for coincidences of multiple maps

open access: yes, 2017
Let $f_1,..., f_k:X\to N$ be maps from a complex $X$ to a compact manifold $N$, $k\ge 2$. In previous works \cite{BLM,MS}, a Lefschetz type theorem was established so that the non-vanishing of a Lefschetz type coincidence class $L(f_1,...,f_k)$ implies ...

Linking and coincidence invariants [PDF]

open access: yes, 2004
Given a link map f into a manifold of the form Q = N \times \Bbb R, when can it be deformed to an unlinked position (in some sense, e.g. where its components map to disjoint \Bbb R-levels) ? Using the language of normal bordism theory as well as the path
