British Journal of Surgery > 103 > 12 > 1608 - 1615

Background The use of oral prophylactic antibiotics for the prevention of surgical‐site infection (SSI) in patients undergoing laparoscopic surgery for colorectal cancer is controversial. The aim of this RCT was to evaluate whether intravenous perioperative antibiotics are inferior to combined preoperative oral and perioperative intravenous antibiotics in this setting. Methods Patients undergoing...

The Hyogo Ion Beam Medical Center was established in May 2001, a leading project of the ‘Hyogo Cancer Strategy’. As its major characteristic, both proton and carbon ion beams can be generated. The accelerator is a synchrotron that can accelerate proton and carbon ion beams at a maximum of 230 and 320 MeV/u, respectively, and the maximum ranges in water are 300 and 200 mm, respectively. Three irradiation...

Revaluation for problem of clinical particle therapy in cell biological effects of proton, carbon-ion and X-ray at Hyogo Ion Beam Medical Center

S. Nagayama, M. Murakami, T. Maeda, M. Baba, więcej

IFMBE Proceedings > World Congress on Medical Physics and Biomedical Engineering, September 7 - 12, 2009, Munich, Germany > 210-212

Hyogo Ion Beam Medical Center (HIBMC) is the world’s only facility to provide both proton and carbon-ion radiotherapy. Based on the characteristic, HIBMC conduct and investigate many comparative studies between proton radiotherapy and carbon-ion radiotherapy. In several comparative studies, we have the problem whether there are differences between proton and carbon-ion radiotherapy. We aimed to compare...

Laparoscopic salvage lateral pelvic lymph node dissection for locally recurrent rectal cancer

T. Akiyoshi, J. Nagata, T. Nagasaki, T. Konishi, więcej

Colorectal Disease > 17 > 10 > O213 - O216

AimThe lateral pelvic lymph nodes are one of the major sites and sources of local recurrence (LR) after surgery for rectal cancer. Salvage lateral pelvic lymph node dissection (LPLD) is potentially curative, but the value of laparoscopic surgery in such cases is unknown. Our aim was to report the technical details of laparoscopic salvage LPLD for LR at these nodes after rectal cancer surgery. MethodThe...

Imperiled freshwater mussels in drainage channels associated with rare agricultural landscape and diverse fish communities

J. N. Negishi, H. Tamaoki, N. Watanabe, S. Nagayama, więcej

Limnology > 2014 > 15 > 3 > 237-247

Identification of landscape structures that predict the distribution of aquatic organisms has the potential to provide a practical management tool for species conservation in agricultural drainage channels. We tested the hypothesis that sites with imperiled freshwater mussels have distinct rural landscape structures and are characterized by the presence of diverse fish communities. In central Japan,...

Colorectal Disease > 15 > 2 > 244 - 251

Aim The aim of this prospective study was to clarify the frequency of male sexual dysfunction after laparoscopic total mesorectal excision (LTME) and to examine the relationship between pelvic autonomic nerve (PAN) preservation status and functional outcomes. Method Candidates for LTME were included in this study. PAN preservation status after LTME was examined in detail by video review. Patients...

Unionoid mussels as an indicator of fish communities: A conceptual framework and empirical evidence

J.N. Negishi, S. Nagayama, M. Kume, S. Sagawa, więcej

Ecological Indicators > 2013 > 24 > Complete > 127-137

We tested the hypothesis that globally imperiled freshwater mussels (Order: Unionoida) can be used as an indicator of fish communities in lowland aquatic systems for relatively small geographic areas (i.e., <100km ² ). The survey was conducted in 13 reaches within a network of agricultural drainage channels and in 9 floodplain backwaters in Central Japan. In each site, the fish community...

Detection of a change in photorealism

JUNICHIRO SEYAMA, RUTH S NAGAYAMA

Japanese Psychological Research > 54 > 4 > 378 - 387

The perceived degree of photorealism is interpreted as reflecting the artificialness or naturalness of images. Natural images (real‐scene photographs) are images with high degrees of naturalness, while artificial images (e.g., paintings) are images with low degrees of naturalness. Alternatively, natural images are images with low degrees of artificialness, while artificial images are images with high...

Photorealism aftereffect

Jun’ichiro Seyama, Ruth S. Nagayama

Psychological Research > 2011 > 75 > 3 > 179-187

This study reports a novel visual aftereffect for photorealism judgments. Participants observed image sequences where a photograph was gradually transformed into an artificial image (a painting or a sketch). Their task was to choose the image that was the category boundary between the photograph and the artificial image among the frames of each image sequence. This task was performed before and after...

An FPGA-based text search engine for approximate regular expression matching

Y Utan, S Wakabayashi, S Nagayama

2010 International Conference on Field-Programmable Technology > 184 - 191

2010 International Conference on Field-Programmable Technology (FPT 2010)

Text search is a procedure to find occurrences of a pattern in a given text where the pattern and each occurrence may have a limited number of differences. Text search is an indispensable technique for bibliographic databases. In this paper, a restricted class of regular expressions is used as patterns, and all substrings in a text that are close to a pattern, possibly with some errors, are located...

Floating-Point Numerical Function Generators Using EVMDDs for Monotone Elementary Functions

S. Nagayama, T. Sasao, J.T. Butler

2009 39th International Symposium on Multiple-Valued Logic > 349 - 355

2009 39th International Symposium on Multiple-Valued Logic. ISMVL 2009

This paper proposes a design method for floating-point numerical function generators (NFGs) using multi-valued decision diagrams (MDDs). Our method applies to monotone elementary functions in which real values are converted into integer values that are represented by edge-valued MDDs (EVMDDs). We show that EVMDDs use fewer nodes by one or two orders of magnitude than two other types of decision diagrams,...

2008 International Conference on Field-Programmable Technology > 297 - 300

2008 International Conference on Field-Programmable Technology

This paper proposes a high-speed string matching circuit for searching a pattern in a given text. In the circuit, a pattern is specified by a class of restricted regular expressions. The architecture of the proposed circuit is a one-dimensional systolic architecture consisting of simple processing units. It can be effectively used for network intrusion detection systems (NIDSs).

2008 11th EUROMICRO Conference on Digital System Design Architectures, Methods and Tools (DSD)

This paper proposes a design method and programmable architectures for numerical function generators (NFGs) of two-variable functions. To realize a two-variable function in hardware, we partition a given domain of the given function into segments, and approximate the function by a polynomial in each segment. This paper introduces two planar segmentation algorithms that efficiently partition a domain...
