Journal ArticleDOI

E. C. Honea,Atsushi Ogura,Cherry A. Murray,Krishnan Raghavachari,W. O. Sprenger,Martin F. Jarrold,W. L. Brown +6 more
TL;DR: In this paper, the structural properties of Si4, Si6 and Si7 clusters were investigated using surface plasmon-polariton enhanced Raman spectroscopy, and it was shown that Si4 is a planar rhombus, and Si6 is a distorted octahedron, while Si7 is a pentagonal bipyramid.
Journal ArticleDOI
Neoadjuvant (Chemo)radiotherapy With Total Mesorectal Excision Only Is Not Sufficient to Prevent Lateral Local Recurrence in Enlarged Nodes: Results of the Multicenter Lateral Node Study of Patients With Low cT3/4 Rectal Cancer
Atsushi Ogura,Atsushi Ogura,Atsushi Ogura,Tsuyoshi Konishi,Tsuyoshi Konishi,Chris Cunningham,Julio Garcia-Aguilar,Henrik Iversen,Shigeo Toda,In Kyu Lee,Hong Xiang Lee,Keisuke Uehara,Peter J Lee,Hein Putter,Cornelis J.H. van de Velde,Geerard L. Beets,Harm J. T. Rutten,Miranda Kusters +17 more
TL;DR: LLR is still a significant problem after (C)RT plus TME in LLNs with a short axis at least 7 mm on pretreatment MRI, and the addition of LLND results in a significantly lower LLR rate.
Journal ArticleDOI
Lateral Nodal Features on Restaging Magnetic Resonance Imaging Associated With Lateral Local Recurrence in Low Rectal Cancer After Neoadjuvant Chemoradiotherapy or Radiotherapy.

Rutten,Jurriaan B. Tuynman,Miranda Kusters +19 more
TL;DR: The main purpose was to identify the factors on primary and restaging MRI associated with LLR in low rectal cancer after (C)RT with TME and to formulate specific guidelines on which patients might benefit from an LLND.
Journal ArticleDOI
HfO2 growth by low-pressure chemical vapor deposition using the Hf(N(C2H5)2)4/O2 gas system
TL;DR: In this paper, a thin HfO2 thin film was deposited on a Si substrate by low pressure chemical vapor deposition using the Hf(N(C2H5)2)4 (tetrakis- diethylamido-hafnium)/O2 gas system.
Journal ArticleDOI
Structures and coalescence behavior of size-selected silicon nanoclusters studied by surface-plasmon-polariton enhanced raman spectroscopy
E. C. Honea,Atsushi Ogura,D. R. Peale,Christian Felix,Cherry A. Murray,Krishnan Raghavachari,W. O. Sprenger,Martin F. Jarrold,W. L. Brown +8 more
TL;DR: In this paper, the structures and coalescence behavior of size-selected, matrix-isolated silicon clusters have been studied using surface-plasmon-polariton enhanced Raman spectroscopy.
