PCF without choice

, 2005
We mainly investigate model of set theory with restricted choice, e.g., ZF + DC + "the family of countable subsets of lambda is well ordered for every lambda" (really local version for a given lambda). In this frame much of pcf theory can be generalized. E.g., there is a class of regular cardinals, and we can prove cardinal inequality.

Secondary Aortoduodenal Fistula Diagnosed after Repeated Gastrointestinal Bleeding Episodes in a Patient With Prior Aortic Graft Surgery

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Secondary aortoduodenal fistula (sADF) is a rare but life‐threatening complication after aortic graft surgery. Diagnosis is often challenging, particularly when contrast‐enhanced computed tomography (CT) and endoscopy results are inconclusive. We report a case in which diagnosis was challenging due to contrast media allergy and non‐diagnostic ...

PCF theory: applications

, 1998
We deal with several pcf problems; we characterize another version of exponentiation: number of kappa-branches in a tree with lambda nodes, deal with existence of independent sets in stable theories, possible cardinality of ultraproduct, the depth of ultraproducts of Boolean Algebras. Also we give cardinal invariant for each lambda with pcf restriction

Endoscopic Removal of Impacted Barium Stools Using a Snare and a Long Hood: A Rare Complication Following Upper Gastrointestinal Barium X‐ray Radiography (With Video)

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Barium sulfate is widely used as a radiographic contrast medium in upper gastrointestinal barium X‐ray radiography for cancer screening in Japan. Although generally considered safe, rare complications such as bowel obstruction due to impacted barium stools can occur.

Association of Preoperative Cognitive Impairment with Poor Outcomes following Transforaminal Lumbar Spinal Fusion Surgery

Formosan Journal of Musculoskeletal Disorders
Background: Preoperative cognitive function (PCF) is gaining attention as a predictor of surgical outcomes due to its association with muscle function and recovery. Its role in postoperative recovery following transforaminal lumbar interbody fusion (TLIF)

Finitely ramified iterated extensions [PDF]

, 2004
Let K be a number field, t a parameter, F=K(t) and f in K[x] a polynomial of degree d. The polynomial P_n(x,t)= f^n(x) - t in F[x] where f^n is the n-fold iterate of f, is absolutely irreducible over F; we compute a recursion for its discriminant.

Successful Colonic Stenting Across the Ileocecal Valve With Severe Malignant Stenosis Using Ultra‐thin Scope and Single‐balloon Overtube

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Self‐expanding metallic stents (SEMSs) are an established palliative option for malignant colonic obstruction, including in cases with proximal lesions. However, SEMS placement across the ileocecal valve (ICV) can be technically challenging because of the anatomical curvature and luminal stenosis. Herein, we report a successful case of colonic

Factors Influencing Resection Time in Endoscopic Submucosal Dissection for Rectal Neuroendocrine Tumors

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The usefulness of endoscopic submucosal dissection (ESD) for rectal neuroendocrine tumors (NETs) is well established. However, factors influencing resection time remain unclear. This study aimed to identify these factors during ESD for rectal NETs.

Gel‐immersion Endoscopic Submucosal Dissection for Superficial Colorectal Neoplasms: A Retrospective Study Comparing Conventional Endoscopic Submucosal Dissection

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel‐immersion endoscopy offers benefits such as buoyancy, traction, and a clear visual field without gas insufflation. While some case reports have described colorectal gel‐immersion endoscopic submucosal dissection (Gi‐ESD), there have been no consecutive case series. This study aimed to clarify the usefulness of Gi‐ESD.
