Idiopathic Superior Mesenteric Vein Thrombosis Resulting in Small Bowel Ischemia in a Pregnant Woman
Background. Small bowel ischemia due to superior mesenteric vein thrombosis (MVT) is rare during pregnancy. However, additional precipitating factors should usually be identified. Case. A 31-year-old woman, pregnant at 34 weeks, was sent to the emergency department because of acute peritonitis. An emergency exploration revealed a segmental gangrene of the small intestine without any mechanical obstruction. Together with the termination of pregnancy, resection of the damaged small bowel was performed, and an end-to-end enterostomy was followed. Based on the operative and pathological findings, small bowel ischemia might be attributed to superior mesenteric vein thrombosis. Conclusion. Hypercoagulation state normally found in pregnant women is believed to lead to this catastrophic condition without other precipitating factors
When Web 3.0 Meets Reality: A Hyperdimensional Fractal Polytope P2P Ecosystems
Web 3.0 opens the world of new existence of the crypto-network-entity, which
is independently defined by the public key pairs for entities and the
connection to the Web 3.0 cyberspace. In this paper, we first discover a
spacetime coordinate system based on fractal polytope in any dimensions with
discrete time offered by blockchain and consensus. Second, the novel network
entities and functions are defined to make use of hyperdimensional
deterministic switching and routing protocols and blockchain-enabled mutual
authentication. In addition to spacetime network architecture, we also define a
multi-tier identity scheme which extends the native Web 3.0
crypto-network-entity to outer cyber and physical world, offering
legal-compliant anonymity and linkability to all derived identifiers of
entities. In this way, we unify the holistic Web 3.0 network based on
persistent spacetime and its entity extension to our cyber and physical world
The Taiwan ECDFS Near-Infrared Survey: Ultra-deep J and Ks Imaging in the Extended Chandra Deep Field-South
We present ultra-deep J and Ks imaging observations covering a 30' * 30' area
of the Extended Chandra Deep Field-South (ECDFS) carried out by our Taiwan
ECDFS Near-Infrared Survey (TENIS). The median 5-sigma limiting magnitudes for
all detected objects in the ECDFS reach 24.5 and 23.9 mag (AB) for J and Ks,
respectively. In the inner 400 arcmin^2 region where the sensitivity is more
uniform, objects as faint as 25.6 and 25.0 mag are detected at 5-sigma. So this
is by far the deepest J and Ks datasets available for the ECDFS. To combine the
TENIS with the Spitzer IRAC data for obtaining better spectral energy
distributions of high-redshift objects, we developed a novel deconvolution
technique (IRACLEAN) to accurately estimate the IRAC fluxes. IRACLEAN can
minimize the effect of blending in the IRAC images caused by the large
point-spread functions and reduce the confusion noise. We applied IRACLEAN to
the images from the Spitzer IRAC/MUSYC Public Legacy in the ECDFS survey
(SIMPLE) and generated a J+Ks selected multi-wavelength catalog including the
photometry of both the TENIS near-infrared and the SIMPLE IRAC data. We
publicly release the data products derived from this work, including the J and
Ks images and the J+Ks selected multiwavelength catalog.Comment: 25 pages, 25 figures, ApJS in pres
