A representation formula is derived for all full-information controllers which satisfy an L/sub infinity / type constraint in the discrete time, time varying, finite horizon case. Unlike earlier work, focus is on the optimal case. The approach is based on the theory of linear quadratic difference games. Necessary and s... |
Electrical stimulation of unmyelinated nerve fibers was analyzed, using bipolar point electrodes in a simple volume conductor model and a dynamic model of Hodgkin-Huxley. The cathodal excitation threshold, the anodal block threshold and the virtual cathodal excitation threshold were calculated by a numerical method wit... |
Fine-grained Web service security policies contain protection assertions that include XPath expressions pointing to the message data to be secured. However, existing security policy (SP) matching approaches don't take into account the structural heterogeneities that may exist between the requestor and provider data. In... |
BACKGROUND/AIMS |
The upper district of the perirenal space is widely open and compliant, especially on the right side. Hepatic growths can, therefore, easily invade the adrenal gland area, mimicking adrenal tumors and vice-versa for adrenal and renal tumors. Data on the nature and exact origin of a mass in this region are important for... |
METHODOLOGY |
The records and imaging documentation of 42 patients with a mass exceeding 6 cm in the hepatorenal space, have been retrospectively reviewed and compared with surgical and histological findings. |
RESULTS |
Among the 14 patients with "non-functioning adrenal tumors," the preoperative diagnosis had been accurate in all but 2 cases where the suspected adrenal lesion turned out, intraoperatively, to be liver growths. These 2 cases are discussed in detail. |
CONCLUSIONS |
The distinction between an intrahepatic and extrahepatic mass challenges modern imaging techniques, and even invasive procedures sometimes fail. A deceptive diagnosis may lead to inappropriate preoperative management and surgical procedures.Ultrahigh resolution parallel Fourier domain optical coherence tomography using... |
We present a parallel Fourier domain optical coherence tomography (FD-OCT) system using Xenon flash lamp. Parallel configuration is implemented by one dimensional illumination and two dimensional detection with a CCD camera. The imaging axial resolution is 2.6μm in air with maximum depth range of ~650μm. The dynamic ra... |
Whatever the technique used may be, the anesthesia for emphysematous patients is always a delicate one. With more and more anesthesiologists dedicated to the use of anesthesia for pulmonary surgery and who are applying the principles described in this article, many emphysematous patients, sometimes severely ill who oth... |

The effect of recurrent postnatal stress on the norepinephrine content of hypothalamus has been studied. Repeated exposure to hunger or to stimulation of the lateral nucleus of the hypothalamus served as stress-producing process. Regardless of their nature, recurrent stresses increased the norepinephrine content of the... |
C57BL/6 mice immunized i.p. with alloantigen (P815 mastocytoma cells) develop cytolytically active thymus-derived (T) splenic lymphocytes. The definition of specific histamine receptor sites on effector T cells has been studied by measuring the in vitro effects of the hormone on cytolytic activity. Histamine was found ... |
This paper discusses how the inclusion of environmental radicals in the teaching of environmental writing in professional and technical communication may benefit students' critical thinking, analysis, and reflection competencies. The origins and positions of eco-terror organizations as juxtaposed to the messages produc... |
The homogeneous requirement of the AHP has stifled its general application and thus hindered the further development of group decision making, which is becoming increasingly popular with the multi-business corporations. In this paper, we adopted the correlation degree of individual preference vectors as the measurement... |
Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy with uncertain histogenesis. Here, we present an unusual presentation of giant MCC of the skin with concomitant intra-abdominal metastasis to pancreas. A 53-year-old man was admitted to our clinic with a giant ulcerated mass in the gluteal region... |
INTRODUCTION |
This is the first prospective cohort study in Singapore to describe the incidence of ischaemic heart disease (IHD) and stroke among Chinese, Malays and Asian Indians. |
MATERIALS AND METHODS |
The Singapore Cardiovascular Cohort Study is a longitudinal follow-up study on a general population cohort of 5920 persons drawn from 3 previous cross-sectional surveys. Morbidity and mortality from IHD and stroke were ascertained by record linkage using a unique identification number with the death registry, Singapore... |
RESULTS |
There were 193 first IHD events and 97 first strokes during 52,806 person-years of observation. The overall incidence of IHD was 3.8/1000 person-years and that of stroke was 1.8/1000 person-years. In both males and females, Indians had the highest IHD incidence, followed by Malays and then Chinese. For males after adju... |
CONCLUSIONS |
This prospective study of both mortality and morbidity has confirmed the higher risk of IHD in Indians. It has also found that Malay females have a higher incidence of stroke, which deserves further study because of its potential public health importance.What Makes Whistleblowers so Threatening?; Comment on 'Cultures o... |
Whistleblowing is defined by the retaliation that those who speak out receive. Why some organizations find it almost impossible not to retaliate depends more on the properties of the organization than the act of the individual whistleblower. These properties are, to greater or lesser degree, present in all organization... |

Abstract Curriculum-based measurement (CBM) tools are increasingly administered through technology-based modalities such as computers and tablets. Two studies were conducted to examine whether students perform similarly on paper-based and tablet-based math fact probes. Ten students completed 1-min addition or multiplic... |
We studied the capacities of naked and protein-coated monosodium urate (MSU) crystals to stimulate superoxide anion (O(2)) release by human polymorphonuclear leukocytes (PMN). Uncoated MSU estimated significant O(2) production by cytochalasin B-treated PMN. Precoating MSU with IgG caused an increase in mean O(2) produc... |
