Quantized filtering for Markovian jump LPV systems with intermittent measurements
Authors: Yao Xiuming , Wu Ligang , Zheng Wei Xing 
Published: September 2011

SUMMARYThis paper investigates the problem of quantized filtering for a class of discrete‐time linear parameter‐varying systems with Markovian switching under data missing. The measured output of the plant is quantized by a logarithmic mode‐independent quantizer. The data missing phenomenon is modeled by a stochastic variable. The purpose of the problem addressed is to design a full‐order filter such that the filtering error dynamics is stochastically stable and the prescribed noise attenuation level in the sense can be achieved. Sufficient conditions are derived for the existence of such filters in terms of parameterized linear matrix inequalities. Then the corresponding filter synthesis problem is transformed into a convex optimization problem that can be efficiently solved by using standard software packages. A simulation example is utilized to demonstrate the usefulness of the developed theoretical results. Copyright © 2011 John Wiley & Sons, Ltd.
Employment of Differential Scanning Calorimetry in Detecting Lard Adulteration in Virgin Coconut Oil
Authors: Mansor T. S. T. , Che Man Y. B. , Shuhaimi M. 
Published: September 2011

AbstractLard (LD) has been commonly used as an adulterant in fats and oils. The similar physical characteristic of virgin coconut oil (VCO) to LD makes LD a desirable adulterant in VCO. Differential scanning calorimetry (DSC) provides unique thermal profiling for each oil and can be used to detect LD adulteration in VCO. In the heating thermogram of the mixture, there was one major endothermic peak (peak A) with a smaller shoulder peak embedded in the major peak that gradually smoothed out to the major peak as the LD% increased. In the cooling thermogram, there were one minor peak (peak B) and two major exothermic peaks, peak C which increased as LD% increased and peak D which decreased in size as the LD% increased. From Stepwise Multiple Linear regression (SMLR) analysis, two independent variables were found to be able to predict LD% adulteration in VCO with R2 (adjusted) of 95.82. The SMLR equation of LD% adulteration in VCO is 293.1 − 11.36 (TeA) − 2.17 (TrD); where TeA is the endset of peak A and TrD is the range of thermal transition for peak D. These parameters can serve as a good measurement index in detecting LD adulteration in VCO.

Published: September 2011

ObjectiveTo provide information regarding the (1) responsiveness and reliability of different outcome measures used with persons who have impairments in upper extremity function and (2) their content validity based on the International Classification of Functioning, Disability, and Health (ICF).Data SourcesMEDLINE, CINAHL, PsycINFO, and EMBASE databases were systematically searched for studies on outcome measures used to evaluate upper extremity function; only studies written in English and published between July 1997 and July 2010 were considered.Study SelectionOne investigator reviewed titles and abstracts of the identified studies to determine whether the studies met predefined eligibility criteria (eg, study design, age <18 years). Another investigator did the same for 70% of the studies.Data ExtractionAll types of outcome measures in the included studies were extracted, and the information retrieved from these outcome measures was linked to the ICF by 2 independent investigators who used standardized linking rules. In addition, studies reporting the clinical responsiveness, interrater reliability, and test‐retest reliability of the outcome measures were identified.Data SynthesisFrom among the 894 studies that were included in this review, 17 most frequently used outcome measures in the different study populations were identified. Five were patient‐reported outcome measures and 12 were clinical outcome measures. The outcome measures show large variability with regard to the areas of functioning and disability addressed. Reliability and responsiveness data are missing for a few outcome measures or for certain populations for which they have been used.ConclusionThis systematic review provides an overview of the outcome measures used to address functioning and disability as they are related to the upper extremity. The results of this study may help clinicians and researchers select the most appropriate outcome measure for their clinical population or research question according to ICF‐based content validity, and additional information on the reliability and responsiveness of the measures is provided. Our findings also can provide directions for further research.
Paleoclimatic and archeological implications of Pleistocene and Holocene environments in Azraq, Jordan
Authors: Jones Matthew D. , Richter Tobias 
Published: September 2011

AbstractWetlands are a key archive for paleoclimatic and archeological work, particularly in arid regions, as they provide a focus for human occupation and preserve environmental information. The sedimentary record from 'Ayn Qasiyya, a spring site on the edge of the Azraq Qa, provides a well-dated sequence through the last glacial–interglacial transition (LGIT) allowing environmental changes in the present-day Jordanian desert to be investigated robustly through this time period for the first time. Results show that the wettest period at the site preceded the last glacial maximum, which itself was characterised by marsh formation and a significant Early Epipaleolithic occupation. A sedimentary hiatus between 16 and 10.5 ka suggests a period of drought in the region although seasonal rains and surface waters still allowed seasonal occupation of the Azraq region. Archeological evidence suggests that conditions had improved by the Late Epipaleolithic, about the time of the North Atlantic Younger Dryas. The changes between wet and dry conditions at the site show similarities to patterns in the eastern Mediterranean and in Arabia suggesting the Jordan interior was influenced by changes in both these regions through the LGIT climatic transition.
Wall shear stress in accelerating turbulent pipe flow
Authors: He S. , Ariyaratne C. , Vardy A. E. 
Published: September 2011

AbstractAn experimental study of wall shear stress in an accelerating flow of water in a pipe ramping between two steady turbulent flows has been undertaken in a large-scale experimental facility. Ensemble averaged mean and r.m.s. of the turbulent fluctuations of wall shear stresses have been derived from hot-film measurements from many repeated runs. The initial Reynolds number and the acceleration rate were varied systematically to give values of a non-dimensional acceleration parameter $k$ ranging from 0.16 to 14. The wall shear stress has been shown to follow a three-stage development. Stage 1 is associated with a period of minimal turbulence response; the measured turbulent wall shear stress remains largely unchanged except for a very slow increase which is readily associated with the stretching of existing turbulent eddies as a result of flow acceleration. In this condition of nearly ‘frozen’ turbulence, the unsteady wall shear stress is driven primarily by flow inertia, initially increasing rapidly and overshooting the pseudo-steady value, but then increasing more slowly and eventually falling below the pseudo-steady value. This variation is predicted by an analytical expression derived from a laminar flow formulation. The start of Stage 2 is marked by the generation of new turbulence causing both the mean and turbulent wall shear stress to increase rapidly, although there is a clear offset between the responses of these two quantities. The turbulent wall shear, reflecting local turbulent activities near the wall, responds first and the mean wall shear, reflecting conditions across the entire flow field, responds somewhat later. In Stage 3, the wall shear stress exhibits a quasi-steady variation. The duration of the initial period of nearly frozen turbulence response close to the wall increases with decreasing initial Reynolds number and with increasing acceleration. The latter is in contrast to the response of turbulence in the core of the flow, which previous measurements have shown to be independent of the rate of acceleration.
CONCORDANCE BETWEEN PARTNERS IN DESIRED WAITING TIME TO BIRTH FOR NEWLYWEDS IN INDIA
Authors: SINGH ABHISHEK , BECKER STAN 
Published: September 2011

SummaryExamining waiting time to birth among newlywed couples is likely to provide insights into the desire for spacing births among newlywed husbands and wives. Data from the Indian National Family Health Survey of 2005–06 are used to examine the desired waiting time (DWT) to birth among newlywed couples. The dependent variable is spousal concordance on desired waiting times. Overall 65% of couples have concordant desired waiting times. Among discordant couples, wives were more likely to want to wait longer than their husbands. Couples from richer wealth quintiles were more likely than couples from the poorest quintile to have concordant desired waiting times. Muslims were less likely than Hindus to have concordant desires. There is a need for spacing contraceptive methods among newlyweds in India. This may have implications for the Indian Family Planning Programme, which to date has largely focused on sterilization. Programmes need to include newlywed husbands to promote use of spacing methods.
Gender, genius and rock and roll in‘Roy Orbison and Friends: A Black and White Night’
Authors: Laver Mark 
Published: September 2011

AbstractTo a considerable extent, the mythology of rock and roll rebellion is predicated upon a similarly mythologised male sexual potency that Simon Frith and Angeld McRobbie have characterised as ‘aggressive, dominating, and boastful, … [constantly seeking] to remind the audience of [its] prowess, [its] control’ (Frith and McRobbie 1990, p. 319). In this article, I look to Roy Orbison – a musician who was a key figure in the genesis of rock and roll, but who nevertheless subverts this phallocentric meta-narrative. Focusing on the 1987 concert film,Roy Orbison and Friends: A Black and White Night, I argue that Orbison's staid performance style, unusual voice and unconventional songwriting as evidenced (and amplified) by that film trouble the purportedly monolithic rock and roll masculinity, and the concomitant mythology of rebellion. At the same time, however, I propose that even as normative masculinity appears to be destabilised, a close reading of the film reveals that the performance situates Orbison within a different masculinist discourse: the 19th-century Romantic discourse of masculine genius that continues to inflect 21st century notions about artists and art music. Thus, inBlack and White Night, normative and non-normative masculinities are thoroughly imbricated, each simultaneously destabilising and reaffirming the other.
‘Brains, means, lyrical ammunition’: hip-hop and socio-racial agency among African Students in Kharkiv, Ukraine
Authors: Helbig Adriana 
Published: September 2011

AbstractIn the last decade, multi-racial hip-hop scenes in Kharkiv, a predominantly Russian-speaking eastern Ukrainian city close to the Russian border, have fostered the development of socially-conscious hip-hop among African students. Drawing on musical elements from their respective home countries, the US and local hip-hop traditions, African male youths use Ukrainian-, Russian- and English-language lyrics to express concerns about socio-economic status, personal struggle and racial inclusion. This study analyses how African musicians use hip-hop as a social means through which to fight the escalating violence against dark-skinned foreigners and migrants. It draws on ethnographic data to identify several ways in which African-performed hip-hop has influenced contemporary public opinions regarding ‘black’ identity in eastern Ukraine.
A girl with extremely refractory Kawasaki disease: an instructive case with unusual course and outcome

Published: September 2011

AbstractKawasaki disease constitutes an acute febrile vasculitis of unknown aetiology. It is considered the most common cause of acquired cardiac failure in children. Although standard treatment comprises intravenous immunoglobulin and aspirin, some children exhibit refractory disease, necessitating the use of alternative therapies such as corticosteroids and anti-tumour necrosis factor-alpha. For these cases, few controlled data are available. This report focuses on an extremely refractory classical Kawasaki disease with coronary artery aneurysms and ongoing inflammation. We discuss the therapeutic approaches and the potential pitfalls undertaken, which led to an unfavourable clinical outcome.
Capillary leak leading to shock in Kawasaki disease without myocardial dysfunction
Authors: Natterer Julia , Perez Marie-Hélène , Di Bernardo Stefano 
Published: September 2011

AbstractKawasaki disease is an acute vasculitis of childhood. Its clinical presentation is well known, and coronary artery aneurysms are classical complications. Shock and pleural or pericardiac effusion are rare presentations of the disease. In intensive care units, the disease may be mistaken for septic shock or toxic shock syndrome. Owing to the fact that immunoglobulin therapy improves the course of the disease, especially if given early, and thus the diagnosis should not be delayed.

Published: September 2011

AbstractPDL (periodontal ligament) is a source of multi‐potent stem cells in humans and their differentiation potential to a cementoblast and osteoblast phenotypes has been shown. Tissue construction from PDL‐derived cells could be considered as a valuable technique for periodontal regenerative medicine. On these basis, we determined the role of CEMP1 (cementum protein 1) as a factor to induce differentiation of human PDL cells in a 3D (three‐dimensional) fashion. Human PDL cells were grown in an RCCS (rotary cell culture system) D‐410 RWV (rotating wall vessel) bioreactor, and maintained in either experimental (CEMP1 2.5 μg/ml) or control media during 4 weeks. Cell proliferation in the presence of CEMP1 was determined. The tissue‐like structure formed was analysed histologically, stained with Alizarin Red and Alcian Blue. ALP (alkaline phosphatase)‐specific activity, immunostaining, RT—PCR (reverse transcription—PCR) and Western blotting were performed to determine the expression of BSP (bone sialoprotein), enamel [AMBN (ameloblastin) and AMEL (amelogenin)], cementum [CAP (cementum attachment protein) and CEMP1] and cartilage‐related proteins (Sox9, aggrecan, types II and X collagens). Our results show that hrCEMP1 (human recombinant CEMP1) promoted cell proliferation by human PDL cells in 3D cultures and induced the formation of a tissue‐like structure resembling bone and/or cementum and material similar to cartilage. The addition of hrCEMP1 to the 3D human PDL cell cultures increased ALP‐specific activity by 2.0‐fold and induced the expression of markers for the osteogenic, cementogenic and chondrogenic phenotypes at the mRNA and protein levels. Our data show that human PDL cells in 3D cultures with the addition of CEMP1 has the potential to be used for the bioengineering reconstruction of periodontal tissues and cartilage since our results suggest that CEMP1 stimulates human PDL cells to differentiate towards different phenotypes.

AbstractAnthracyclines are potent cytostatic drugs, the correct dosage being critical to avoid possible cardiac side effects. ABCC1 [ATP‐binding cassette, sub‐family C, member 1; also denoted as MRP1 (multidrug resistance‐associated protein 1)] is expressed in the heart and takes part in the detoxification and protection of cells from the toxic effects of xenobiotics, including anthracyclines. Our objective was to search for associations between LV (left ventricular) function and single‐nucleotide polymorphisms of the ABCC1 gene in children receiving anthracycline chemotherapy. Data of 235 paediatric patients with acute lymphoblastic leukaemia was analysed. Patients were followed‐up by echocardiography (median follow‐up 6.3 years). Nine polymorphisms in the ABCC1 gene were genotyped. The ABCC1 rs3743527TT genotype and rs3743527TT—rs246221TC/TT genotype combination were associated with lower LVFS (left ventricular fractional shortening) after chemotherapy. The results suggest that genetic variants in the ABCC1 gene influence anthracycline‐induced LV dysfunction.
Developmental and Preschool Psychology in the Ukrainian SSR
Authors: Holowinsky Ivan Z. 
Published: September 2011

In the past decade we have witnessed increased interest on the part of psychologists and educators in developmental and preschool psychology, as well as in the application of psychological findings to the problems of learning disorders. The realization that cognitive development depends upon continuous interaction between the developing organism and the environment gave impetus to the current research on preschool children.Even a superficial review of psychological literature will reveal worldwide interest in developmental and preschool psychology. Names like Piaget and Inhalder in Switzerland, as well as Bruner and Kagan in the USA, are internationally recognized. Very few Western psychologists, however, will recognize Kostiuk, Zaporozhets or Zinchenko as Ukrainian psychologists. Among Western psychologists they are simply recognized as “Soviet” psychologists. While most Western psychologists recognize that the Soviet Union as a political entity is not identical with Russia, some unfortunately identify psychologists in the Soviet Union as Russian psychologists.
Developmental Changes in Word Recognition: An Information-Processing Account
Authors: Pring Linda , Snowling Maggie 
Published: September 2011

Two experiments examining developmental changes in the use of context in single word reading are reported. The first experiment investigated how effectively children can access conceptual knowledge and use this to help their word recognition. The results indicated that young readers can on demand direct their attention to semantic information, and this allows them to reap a relatively greater benefit from context than older more skilful readers. The second experiment attempted to clarify the way such use of contextual information might help in the specific case when a child attempts to decode a new word for the first time. Skilled and unskilled readers pronounced pseudohomophonic nonwords faster when they were primed by a semantic context, and the context effect was greater for unskilled readers. The nonword's graphemic similarity to a lexical item was also important. In general, the results were consistent with Stanovich's (1980) interactive-compensatory model of reading, and they suggest that in learning to read, several already existing stores of information (e.g. auditory, visual and conceptual) are integrated in order to achieve a solution to the word recognition problem.
Towards an Exemplar Model of Face Processing: The Effects of Race and Distinctiveness
Authors: Valentine Tim , Endo Mitsuo 
Published: September 2011

Valentine (1991a, 1991b) described a theoretical framework for face recognition in which faces are encoded as locations in a multidimensional space. It was argued that this approach could provide a unified account of the effects of distinctiveness, inversion, and race on face recognition. In this paper we evaluate the ability of this theoretical framework to account for the effects of distinctiveness and race in four experiments in which white British and Japanese faces served as stimuli and both white British and Japanese students acted as subjects. In a recognition memory experiment the expected “own-race bias” was observed as a Race of Subject × Race of Face interaction. Distinctive faces were recognized more accurately than typical faces, but the effect of distinctiveness did not interact with the race of face or the race of subject. Typical faces were classified faster than distinctive faces in a task in which intact faces had to be distinguished from jumbled faces, as found in earlier work, and the effect of distinctiveness did not interact with the race of face or race of subject. In contrast, a task in which subjects classified faces according to their race did show a greater effect of distinctiveness for own-race faces. The results are discussed in relation to the two specific models within the multidimensional space framework identified by Valentine (1991a): a purely exemplar-based model and a norm-based coding model. It is argued that these results are more easily accommodated in terms of a purely exemplar-based model. Some conceptual problems in applying the norm-based coding model to the effect of race are discussed.
