Risk-limiting post-election audits guarantee a high probability of correcting incorrect electoral outcomes, regardless of why the outcomes are incorrect. Two types of risk-limiting post-election vote tabulation audits are comparison audits and ballot-polling audits. Comparison audits check some of the subtotals reporte... |
The popularity of network-based control systems (NBCS) is continuously growing. One of the most intriguing aspects is the transportation of control network data over IP-based networks as standardized in EIA-852. To a large extent the actual quality of control (QoC) in such systems depends on the network timing such as ... |
Alleviating metropolitan traffic congestion is one of the major issues faced throughout the world. On one hand, the falling car occupancy rates indicate that more than 80% of the congestion can be attributed to the empty car seats. A highly promising approach to combat traffic congestion is dynamic ride sharing, which ... |
Solitons have been found in many physical branches. Previous investigations on solitons mainly focused on various nonlinear dispersive media in nature. It is well known that in the nonlinear dispersive medium, soliton formation is due to the exact balance between the nonlinearity and the group velocity dispersion (GVD)... |

Legionella pneumophila and related species were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis for outer membrane proteins. Of the 10 species examined, 9 contained a 24-kilodalton (kDa) major outer membrane protein (MOMP) that was resolvable only when outer membrane material was heated in the pre... |
Second-order elastic constants cannot be applied directly to the study of the mechanical stability of a stressed material. We derive general expressions for stability criteria by constructing appropriate thermodynamic potentials. For a system under isotropic initial stress, elastic stiffness coefficients which govern s... |
Biological specificity is usually described in terms of the lock-and-key metaphor. However, this metaphor is to a certain extent misleading and does not grasp the complexity underlying biological specificity. The failure of the lock-and-key metaphor makes it difficult to understand immune recognition. This is the reaso... |
In order to get better results and faster speed on medical image fusion, a method based on non-sub sampled contour let transform in compressed sensing was proposed. Because of the large sparsity and sharp contrast between the black and the white of medical images, the energy and average gradient were utilized to design... |
Abstract A scratch test in the intermediate load range between the nanoscratch test and the microscratch test is used to determine the failure properties of thin coatings and their interface with the substrate on which the coating was deposited. The technique consists in drawing a stylus with a rounded conical tip alon... |
BACKGROUND |
On 22 July 2011, Norway was struck by two terror attacks. Seventy-seven people were killed, and many injured. Rescue workers from five occupational groups and unaffiliated volunteers faced death and despair to assist victims. |
AIMS |
To investigate the level of, and associations between, demographic variables, exposure and work-related variables and post-traumatic stress symptoms (PTSS). |
METHODS |
A cross-sectional study of general and psychosocial health care personnel, police officers, firefighters, affiliated and unaffiliated volunteers were conducted ~10 months after the terror attacks. The respondents answered a self-reported questionnaire. Post-traumatic stress disorder (PTSD) Checklist - specific (PCL-S) ... |
RESULTS |
There were 1790 participants; response rate was 61%. About 70% of the professional rescue workers had previous work experience with similar tasks or had participated in training or disaster drills. They assessed the rescue work as a success. Firefighters and unaffiliated volunteers reported more perceived threat compar... |
CONCLUSIONS |
In the aftermath of a terror attack, professional rescue workers appear to be largely protected from post-traumatic stress reactions, while unaffiliated volunteers seem to be at higher risk.Evidence from cancer intervention and biomarker studies and the development of biochemical markers. |
Evidence from intervention trials with vitamins E and C and beta-carotene are reviewed as well as evidence from trials that have used intermediate endpoints with a special emphasis on biomarkers of cancer of the colorectum. The methodologic issues that require resolution before a second generation of clinical trials ar... |
Although the ability to vocalize is widespread among tortoises, the mechanisms of sound production in chelonians remain undescribed. In this study, we analyze the morphology and histology of the larynx of three species of Testudinidae (Testudo hermanni, T. graeca, and T. marginata) in order to ascertain the presence of... |
Lithium-sulfur (Li-S) batteries and lithium-selenium (Li-Se) batteries that contain only one single active element have unique advantages and disadvantages. Inspired by ternary lithium batteries, multielement chalcogenide compounds with integrated advantages may improve upon the performance of lithium-chalcogenide batt... |
Defects in the inner canthal area are generally repaired by full-thickness skin grafts, V-Y advancement flap, or frontal flap. Each of these techniques may give some problems in restoring the functional or aesthetic features of that region, or both. To avoid these inconveniences, we performed the reconstruction of the ... |

One possible solution relates to the use of semi-active devices, such as the ones based on magneto-rheologic fluids. These devices need guaranteed electrical power, together wi... |
Mutations in GDF-5, a member of the TGF-beta superfamily, result in the autosomal recessive syndromes brachypod (bp) in mice and Hunter-Thompson and Grebe-type chondrodysplasias in humans. These syndromes are all characterised by the shortening of the appendicular skeleton and loss or abnormal development of some joint... |
Philosophy, and analytic metaphysics in particular, is usually described as an armchair discipline, and exactly for such an armchair methodology it has been the target of ferocious criticisms. In this paper, I argue that the theoretical right to conduct metaphysics from the armchair can be defended understanding metaph... |
The Defense of Marriage Act (DOMA) effectively bars a U.S. citizen from sponsoring a foreign national same-sex spouse to immigrate to the United States. The plenary power doctrine-a standard of extraordinary deference to the political branches in immigration-may hinder judicial scrutiny of DOMA in the immigration conte... |
There exists much uncertainty about consumer attitudes towards genetically modified foods. If it happens that sufficient (insufficient) acres are planted under non-modified seed to meet post-harvest demand, then a price premium will not (will) emerge for the non-modified varieties. A non-linearity originates in the fac... |
Neurohistological, histochemical, electron-microscopic and biometric techniques were used to study the response of rat brain to irradiation within a wide range of doses. Nerve cells were shown to be highly radioresistant. At the same time, synapses and blood-brain barrier structures were highly radiosensitive. The path... |
OBJECTIVE |
Circumstances surrounding the New Madrid earthquake prediction on Dec. 3, 1990, offered a unique opportunity to study the effects of a disaster warning stage on children and adolescents. |
METHOD |
An initial structured interview was administered to 553 third- and 10th-grade students before December 3, with follow-up interviews conducted 6-8 weeks later. |
RESULTS |
This study documents the existence of a mild but prevalent PTSD-like reaction that arose from exposure to a prediction of disaster. |
CONCLUSIONS |
Further study of anticipatory stress reactions is needed to provide insights into the development of methods for providing support to children during disaster warnings.Assessing the thermal diffusivity and principal directions of moving samples by infrared thermography: towards fiber orientation monitoring in productio... |
We propose a methodology to determine the thermal diffusivity of both isotropic and anisotropic samples when they move at constant speed, using laser spot thermography with continuous illumination. In the case of anisotropic samples, the method does not require knowledge of the thermal principal directions and is able ... |
An important unresolved issue in antifolate pharmacology is the basis for the observation that the major portion of cellular tetrahydrofolate cofactors is preserved after dihydrofolate reductase activity is abolished by antifolates despite the fact that tetrahydrofolate cofactor-dependent purine and pyrimidine biosynth... |
