On equipartition of energy and integrals of Generalized Langevin Equations with generalized Rouse kernel

Abstract. We show that if the motion of a particle in a linear viscoelastic liquid is described by a Generalized Langevin Equation with generalized Rouse kernel, then the resulting velocity process satisfies equipartition of energy. In doing so, we present a closed formula for the improper integration along the positive line of the product of a rational polynomial function and of even powers of the sinc function. The only requirements on the rational function are sufficient decay at infinity, no purely real poles and only simple nonzero poles. In such, our results are applicable to a family of exponentially decaying kernels. The proof of the integral result follows from the residue theorem and equipartition of energy is a natural consequence thereof. Furthermore, we apply the integral result to obtain an explicit formulae for the covariance of the position process both in the general case and for the Rouse kernel. We also discuss a numerical algorithm based on residue calculus to evaluate the covariance for the Rouse kernel at arbitrary times.
Results of long‐term deferiprone (L1) therapy: a report by the International Study Group on Oral Iron Chelators

Summary This report updates the combined experience of four centres involved in the long‐term treatment of transfusional iron overload in 84 patients with the oral iron chelator deferiprone (L1) over 167 patient‐years. The source of L1 was variable, including two university research laboratories and three pharmaceutical firms. Compliance was rated as excellent in 48%, intermediate in 36%, and poor in 16% of patients. On a mean L1 dose of 73–81 mg/kg/d, urinary iron excretion was stable, at around 0 5 mg/kg/d, with no indication of a diminishing response with time. Serum ferritin showed a very steady decrease with time from an initial mean ±1SD of 4207 ±3118 to 1779 ± 1154μg/1 after 48 months (P< 0–001). 17 patients abandoned L1 therapy, Major complications of L1 requiring permanent discontinuation of treatment included agranulocytosis (three), severe nausea (four), arthritis (two) and persistent liver dysfunction (one). The remaining patients abandoned treatment because of low compliance (three) and conditions unrelated to L1 toxicity (four). Lesser complications permitting continued L1 treatment included transient mild neutropenia (four), zinc deficiency (12), transient increase in liver enzymes (37), moderate nausea (three) and arthropathy (17). There was no treatment‐related mortality. Although the complications associated with L1 treatment are significant and require close monitoring, they do not preclude effective long‐term therapy in the vast majority of patients. Further well‐controlled prospective studies of L1 are required in order to enable proper judgement of its suitability for general long‐term clinical use.
The effect of exchange transfusion on serum ionized calcium.

The effect of exchange transfusion on serum ionized calcium concentration was studied during 27 exchange transfusions on 18 newborn infants. When heparinized blood is used negligible changes in serum calcium ion concentration occur, whereas with acid citrate dextrose (ACD) blood a profound fall in ionized calcium occurs which is not prevented by the infusion of calcium gluconate in the usually recommended amount. Ionized calcium levels could not be correlated with the infant9s clinical state during the exchange transfusion.
Inequality, Distributive Justice and Political Participation: An Analysis of the Case of Chile

Political participation has frequently been associated with individual resources; that is, individuals with higher incomes, higher educational levels and more time tend to participate in the political process to a greater extent than other individuals do. The present study suggests that in addition to resources, an individual’s beliefs about economic distribution are an important determinant of participation both in elections and in protests. Based on the analysis of the Chilean data from the Latin American Public Opinion Project (LAPOP) 2012, the results suggest that distributive beliefs are associated primarily with participation in protests.
Lower-dose therapy with traditional neuroleptics in chronically hospitalized schizophrenic patients.

Several recent studies have shown that relatively low doses and low blood levels of neuroleptics are often as effective as high doses of these drugs both in the treatment of an acute exacerbation of schizophrenia 1-3 and in the maintenance treatment of stabilized outpatients with schizophrenia. 4,5 Yet, some patients with chronic schizophrenia or related disorders, hospitalized for extended periods, are treated with relatively high doses of neuroleptics for many years. The efficacy of low doses vs standard or high doses of traditional neuroleptics in this group of patients has not been extensively investigated and thus represents an important gap in the low-dose research and treatment strategy. This letter reports an attempt to address this important clinical question. Patients and Methods. In the course of clinical management of a service of chronically psychotic female patients, a program of neuroleptic dosage reduction combined with quantitative monitoring of their psychopathologic condition was
Efficiency optimization of an induction machine using optimal flux control

This paper presents the efficiency optimization of a variable speed induction machine (VSIM) using an Optimal Flux Control (OFC). To optimize the efficiency, an approach called as Maximum Torque per Ampere (MTA) algorithm was used to provide the constant optimal flux (COF) during the speed control, where the minimisation of the winding losses is considered along the operation. In this paper, the total power and total power loss during machine motoring is presented. The performance of the proposed OFC design is compared with the conventional open-loop scalar-control (OLSC) method. From the finding, it was found that the COF approach provides better performance than the OLSC in terms of settling time, steady-state error and efficiency.
Handwritten character recognition using some (anti)-diagonal structural features

In this paper, we present a methodology for off-line handwritten character recognition. The proposed methodology relies on a new feature extraction technique based on structural characteristics, histograms and profiles. As novelty, we propose the extraction of new eight histograms and four profiles from the $32\times 32$ matrices that represent the characters, creating 256-dimension feature vectors. These feature vectors are then employed in a classification step that uses a $k$-means algorithm. We performed experiments using the NIST database to evaluate our proposal. Namely, the recognition system was trained using 1000 samples and 64 classes for each symbol and was tested on 500 samples for each symbol. We obtain promising accuracy results that vary from 81.74\% to 93.75\%, depending on the difficulty of the character category, showing better accuracy results than other methods from the state of the art also based on structural characteristics.

A preliminary investigation of complex adaptive systems as a model for explaining organisational change caused by the introduction of health information systems

This paper documents the preliminary development of a framework for evaluating organisational change processes during the implementation of an electronic nursing documentation system in residential aged care facilities. It starts with a brief outline of organisational change processes. This is followed by a more detailed exposition of the principles underlying complex adaptive systems (CAS) theory, where we explain how mathematical concepts can be used to illuminate qualitative research approaches. Finally we present some preliminary findings on the facilitators and barriers for the introduction of the electronic documentation system, explained with reference to the CAS theory, based on analysis of interviews with care staff members in a residential aged care facility. While there are clear benefits from electronic nursing documentation, we also identified significant risks, and possible unintended consequences, both positive and negative.
Some of the Early Events Underlying Th2. Cell Maturation and Susceptibility to Leishmania major Infection in BALB/c Mice

Abstract The first experimental evidence for the development of polarized CD4+ Th1 and Th2 responses in vivo has been obtained using the murine model of infection with Leishmania major, an intracellular parasite of macrophages in their vertebrate host. Genetically determined resistance and susceptibility to infection with this parasite have been clearly demonstrated to result from the development of polarized Th1 and Th2 responses, respectively. Using this model system, the dominant role of cytokines in the induction of polarized CD4+ responses has been validated in vivo. The requisite role of IL-4 in mediating both Th2 differentiation and susceptibility to infection in BALB/c mice has directed interest towards the search for evidence of IL-4 production early after infection and identification of its cellular source. We have been able to demonstrate a burst of IL-4 production in susceptible BALB/c mice within the first day of infection with L. major and could establish that this rapidly produced IL-4 instructed Th2 lineage commitment of subsequently activated CD4+ T cells and stabilized this commitment by downregulating IL-12 Rβ2 chain expression, resulting in susceptibility to infection. Strikingly, this early IL-4 response to infection resulted from the cognate recognition of a single epitope in a distinctive antigen, LACK, from this complex microorganism by a restricted population of CD4+ T cells that express Vβ4-Vα8 T cell receptors.
The Literary Blues Tradition@@@Blues, Ideology, and Afro-American Literature: A Vernacular Theory.

Relating the blues to American social and literary history and to Afro-American expressive culture, Houston A. Baker, Jr., offers the basis for a broader study of American culture at its "vernacular" level. He shows how the "blues voice" and its economic undertones are both central to the American narrative and characteristic of the Afro-American way of telling it.
Contrasting chronic fatigue syndrome versus myalgic encephalomyelitis/chronic fatigue syndrome

Background: Much debate is transpiring regarding whether chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME) are different illnesses. Several prior studies that compared the Fukuda et al. CFS criteria to the Canadian ME/CFS criteria found that the Canadian criteria identified patients with more functional impairments and greater physical, mental, and cognitive problems than those who met Fukuda et al. criteria. These samples were located in the Chicago metropolitan area, so the results could not be generalized to other locations. In addition, past studies used a symptom questionnaire that was not specifically developed to tap the Canadian criteria. Purpose: The present comparative study of CFS and ME/CFS criteria was intended to correct the limitations of prior studies. Methods: This article used data from three distinct samples to compare patients who met criteria for the ME/CFS Canadian clinical case definition to those who met the Fukuda et al. CFS case definition. Results: Findings indicated that fewer individuals met the Canadian criteria than the Fukuda et al. criteria. Those who met the Canadian criteria evidenced more severe symptoms and physical functioning impairment. Conclusions: Future research should continue to compare existing case definitions and determine which criteria best select for this illness.
Influence of soil geochemical and physical properties on the sorption and bioaccessibility of chromium(III).

There are numerous Cr(III)-contaminated sites on Department of Defense (DoD) and Department of Energy (DOE) lands that are awaiting possible clean up and closure. Ingestion of contaminated soil by children is the risk driver that generally motivates the likelihood of site remediation. The purpose of this study was to develop a simple statistical model based on common soil properties to estimate the hioaccessibility of Cr(III)-contaminated soil upon ingestion. Thirty-five uncontaminated soils from seven major soil orders, whose properties were similar to numerous U.S. DoD contaminated sites, were treated with Cr(III) and aged. Statistical analysis revealed that Cr(III) sorption (e.g., adsorption and surface precipitation) by the soils was strongly correlated with the clay content, total inorganic C, pH, and the cation exchange capacity of the soils. Soils with higher quantities of clay, inorganic C (i.e., carbonates), higher pH, and higher cation exchange capacity generally sequestered more Cr(III). The amount of Cr(III) bioaccessible from the treated soils was determined with a physiologically based extraction test (PBET) that was designed to simulate the digestive process of the stomach. The bioaccessibility of Cr(III) varied widely as a function of soil type with most soils limiting bioaccessibility to <45 and <30% after I and 100 d soil-Cr aging, respectively. Statistical analysis showed the bioaccessibility of Cr(III) on soil was again related to the clay and total inorganic carbon (TIC) content of the soil. Bioaccessibility decreased as the soil TIC content increased and as the clay content decreased. The model yielded an equation based on common soil properties that could be used to predict the Cr(III) bioaccessibility in soils with a reasonable level of confidence.
Antenna evaluation for wireless data transmission in magnetic resonance imaging

Wireless links in a magnetic resonance imaging (MRI) device can replace cabled transmission of physiological data or magnetic resonance sensor signals which increases comfort for the patient. As the imaging device is located in a shielded chamber a wireless link can use all frequency ranges above the resonance frequency of the excited nuclei. Therefore we studied two channels, one containing the GSM-900 band and a second containing the 24GHz ISM band.
Can Institutional Investors Improve Corporate Governance Through Collective Action?

Can institutional investors generate sufficient power through collective action to drive improvements in governance? We use proprietary data on the private communications of a formal coalition of Canadian institutional investors and find that its private engagements influenced firms’ adoption of majority voting and say-on-pay advisory votes, improved compensation structure and disclosure, and influenced CEO incentive intensity. Spillovers to non-engaged firms occur through board interlocks and to firms in which the CCGG is expected to be more powerful in a voting contest. This form of activism is both a substitute and complement to other interventions to address governance concerns.  Doidge and Dyck are at the Rotman School of Management, University of Toronto.

Modeling the Integration of Parasitoid, Insecticide, and Transgenic Insecticidal Crop for the Long-Term Control of an Insect Pest

ABSTRACT The tools of insect pest management include host plant resistance, biological control, and insecticides and how they are integrated will influence the durability of each. We created a detailed model of the population dynamics and population genetics of the diamondback moth, Plutella xylostella L. , and its parasitoid, Diadegma insulare (Cresson), to study long-term pest management in broccoli Brassica oleracea L. Given this pest's history of evolving resistance to various toxins, we also evaluated the evolution of resistance to transgenic insecticidal Bt broccoli (expressing Cry1Ac) and two types of insecticides. Simulations demonstrated that parasitism provided the most reliable, long-term control of P. xylostella populations. Use of Bt broccoli with a 10% insecticide-free refuge did not reduce the long-term contribution of parasitism to pest control. Small refuges within Bt broccoli fields can delay evolution of resistance >30 generations if resistance alleles are rare in the pest population. However, the effectiveness of these refuges can be compromised by insecticide use. Rainfall mortality during the pest's egg and neonate stages significantly influences pest control but especially resistance management. Our model results support the idea that Bt crops and biological control can be integrated in integrated pest management and actually synergistically support each other. However, the planting and maintenance of toxin-free refuges are critical to this integration.
Bipartite 2‐Factorizations of Complete Multipartite Graphs

It is shown that if K is any regular complete multipartite graph of even degree, and F is any bipartite 2‐factor of K, then there exists a factorization of K into F; except that there is no factorization of K6, 6 into F when F is the union of two disjoint 6‐cycles.
The role of psychological mechanisms to insomnia in its early phase: A focus on arousal, distress, and sleep-related beliefs

The aim of this study was to investigate whether arousal, distress, and sleep-related beliefs are related to the development of insomnia. From a randomly selected sample of 3600 individuals from the general population (50–60 years), 2239 participants filled out a baseline and 1-year follow-up questionnaire. Logistic regression and cluster analysis were used to investigate whether the psychological mechanisms were related to the development of new cases of insomnia over 1 year and whether it was possible to classify the participants based on their profiles of psychological mechanisms. The results showed that arousal, sleep-related beliefs, and depression were significantly related to the development of new cases of insomnia (13% of the variance). High scores on all three mechanisms were characteristic of one cluster (18% new cases of insomnia) and low scores on the mechanisms of another cluster (5% new cases of insomnia). This study shows that arousal, sleep-related beliefs, and depression are associated with the development of insomnia, and that psychological mechanisms often co-occur in individuals who develop insomnia.
Surface proteins of simian‐virus‐40‐transformed cells

Mammalian cells transformed in tissue culture by SV40 were shown to contain, in addition to the SV40‐coded 94,000 d large T antigen and the 20, 000 d small t antigen, a ∼ 56,000 d cellular protein, which specifically precipitates with sera of animals bearing SV40‐induced tumor (s) (tumor or T serum). We investigated the presence of these three proteins at the surface of logarithmically growing SV40‐transformed cloned mouse cells, after metabolic labelling with [35S]‐methionine for 3 h. The 56,000 d protein was found to be susceptible to digestion by trypsin under conditions which did not disrupt the cells, while no small t antigen was found to be digested. Both the 56,000 d cellular protein and the SV40 large T antigen were susceptible to lactoperoxi‐dase‐catalyzed iodination from the outside of intact cells. Trypsin treatment removed both the iodinated 56,000 d protein and the iodinated SV40 large T antigen. These experiments indicated that (a certain amount of) the 56,000 d protein and a relatively small amount of the large T antigen (which is present mainly in the nucleus) are present on the cell surface. The results confirm and extend independent experiments using subcellular frac‐tionation techniques (Luborsky and Chandrasekaran, 1980; Soule and Butel, 1979). After heat treatment (at 50°C for 30 min) of the whole‐cell extract the 56,000 d cellular protein was precipitated by the tumor serum in the absence of precipitation of SV40 large T antigen. This result showed that the 56,000 d protein is more (thermostable (in the whole‐cell extract) than the SV40 large T antigen, and also indicated that the tumor serum employed had antibodies against the 56,000 d cellular antigen. The heat‐treated whole‐cell extract of SV40‐transformed mouse cells was able to immunize and fully protect mice against a lethal tumorigenic dose of SV40‐transformed cells. These results suggest the need for further experiments to characterize the chemical and immunologic properties of the 56,000 d protein.
