The quantum symmetric XXZ chain at Delta=-1/2, alternating sign matrices and plane partitions [PDF]

open access: yesJ.Phys.A 34 (2001) L265-L270, 2001
We consider the groundstate wavefunction of the quantum symmetric antiferromagnetic XXZ chain with open and twisted boundary conditions at $\Delta=-{1/2}$, along with the groundstate wavefunction of the corresponding O($n$) loop model at $n=1$. Based on exact results for finite-size systems, sums involving the wavefunction components, and in some cases

Nutritional benefits of pancreas‐sparing total duodenectomy for severe duodenal polyposis in patients with familial adenomatous polyposis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The postoperative nutritional status of patients with familial adenomatous polyposis who underwent pancreas‐sparing total duodenectomy was better than that of patients who underwent pancreaticoduodenectomy. This study provides the first direct comparison of postoperative nutritional outcomes between patients with pancreas‐sparing total duodenectomy and

Network-based community detection of comorbidities and their association with SARS-CoV-2 virus during COVID-19 pathogenesis [PDF]

open access: yesarXiv, 2022
Recent studies emphasized the necessity to identify key (human) biological processes and pathways targeted by the Coronaviridae family of viruses, especially SARS-CoV-2. COVID-19 caused up to 33-55\% death rates in COVID-19 patients with malignant neoplasms and Alzheimer's disease.

Magnetization Plateaux in Bethe Ansatz Solvable Spin-S Ladders [PDF]

open access: yesPhys. Rev. B 68 (2003) 024418, 2003
We examine the properties of the Bethe Ansatz solvable two- and three-leg spin-$S$ ladders. These models include Heisenberg rung interactions of arbitrary strength and thus capture the physics of the spin-$S$ Heisenberg ladders for strong rung coupling.

A multicenter randomized controlled trial evaluating the effect of the use of an anti‐adhesion barrier for diverting ileostomy on the multidimensional workload in minimally invasive surgery for rectal cancer (YCOG 2005: The ADOBARRIER study)

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This multicenter, single‐blind, randomized, controlled trial was conducted to evaluate the multidimensional workload of the first operator during ileostomy closure using the SURG‐TLX between groups with and without the use of the spray‐type anti‐adhesion material during diverting ileostomy construction.

The Rotor Model and Combinatorics [PDF]

open access: yesInt. J. Mod. Phys. B 16 (2002) 1883-1890, 2002
We examine the groundstate wavefunction of the rotor model for different boundary conditions. Three conjectures are made on the appearance of numbers enumerating alternating sign matrices. In addition to those occurring in the O($n=1$) model we find the number $A_{\rm V}(2m+1;3)$, which 3-enumerates vertically symmetric alternating sign matrices.

Reoperative pouch surgery for suspected Crohn's‐related complications aided by biologic coverage: Early experience from an inflammatory bowel disease center

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This paper demonstrates that revisional/redo ileal pouch anal anastomosis (IPAA) surgery with concurrent biologic therapy provides a viable, stoma‐free alternative for patients with Crohn's disease‐like complications, showing a high functioning pouch rate and expanding options for managing pouch failure.

Optimal Extent of Lymph Node Dissection for Non‐Metastatic Colon Cancer by Tumor Location: Evaluation of the Therapeutic Value Index for Each Lymph Node Station

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Lymph node dissection of the main nodes along the feeding artery has a therapeutic value in early‐stage colon cancers. Meanwhile, the significance of #253 dissection for descending colon cancer requires further discussion. ABSTRACT Aims To determine the optimal extent of lymph node dissection for non‐metastatic colon cancer by tumor location based on ...
