Privacy protection in human-centric healthcare home environment

The medical environment has evolved from the one centered on the hospital diagnosis to that centered on the healthcare. The healthcare environment is the technology enabling the remote diagnosis for personal healthcare not only of lonesome old men but also of general households. In relation with it, an international standard technology was published recently that transmits the information from the devices to measure the biometric information of persons to the healthcare center or hospital. But, for its actual application into each household, it is necessary to solve the privacy protection problem. Therefore, this paper proposes a new architecture and system to secure the privacy of person for the newly published international standard technology. The proposed technology is expected to provide a more secure and realistic alternative in the future human-centric healthcare home environment. Copyright © 2012 John Wiley & Sons, Ltd.
Experiential and Logical Structures within Karo Batak Nominal Groups: A Study in Systemic Functional Linguistics

This article studies the ideational function within the Nominal Group (NG) in Karo Batak Language (KBL) which is dominantly spoken in Karo Regency, North Sumatra Province (Indonesia). This paper specifically discusses the experiential and logical structures in KBL. The perspective of this study is of course related to Halliday’s Systemic Functional Linguistics (SFL). Halliday (1986, 2004) argues ideational function can be divided into two subfunctions; the first is the experiential function which is concerned with deictic, numerative, classifier and epithet, thing, and qualifier. The second refers to logical one which is related to modifier, premodifier, and post-modifier. The objectives of the study are to describe the experiential and logical structures within NG and to describe word classes forming NG. The results show that experiential structures within NG have some formations and can be seen as follows: (1) Entity ^ Classifier ^ Deictic ^ Numerative ^ Epithet, (2) Entity ^ Classifier ^ Deictic ^ Epithet ^ Epithet ^ Numerative ^ Epithet, (3) Numerative ^ Entity ^ Classifier ^ Deictic ^ Epithet, (4) Entity ^ Classifier ^ Epithet ^ Deictic ^ Epithet, (5) Numerative ^ Entity ^ Classifier ^ Deictic, (6) Entity ^ Classifier ^ Deictic ^ Epithet ^ Epithet ^ Numerative ^ Epithet. Whereas, the logical structure owns some simple formations such as (1) Thing ^ Modification, (2) Modifier ^ Thing, (3) Thing ^ Modifier, (4) Modifier ^ Thing, and (5) Premodification ^ Thing ^ Post-modification.
Effects of PAPR reduction on HPA predistortion

There have been many papers concerning about the peak to average power ratio (PAPR) reduction and high power amplifier (HPA) linearization techniques for wireless OFDM communication systems. Few papers, however, make deep analysis on the relation between these two techniques. Based on Saleh's memoryless traveling wave tube amplifier (TWTA) model, computer simulations and analysis in this paper demonstrates that, especially when the HPA is working near or in the saturation region, a predistorter ceases to be in effect. In such cases, PAPR reduction techniques may be resorted to help to improve the adjacent channel interference (ACI), BER performances and HPA efficiency.
Interrupter resistance and wheezing phenotypes at 4 years of age.

It is difficult to distinguish young children with respiratory symptoms who will develop asthma from those with transient symptoms only. Measurement of interrupter resistance may help to identify children at high risk of asthma. The aim of this study is to compare interrupter resistance in 4-year-old children with different wheezing phenotypes. All children participated in the Prevention and Incidence of Asthma and Mite Allergy cohort, a prospective birth cohort of more than 4,000 children. At 4 years of age, data on interrupter resistance plus wheezing phenotype were available for 838 children. Mean interrupter resistance values (95% confidence interval) were 0.95 (0.93, 0.97), 0.95 (0.92, 0.98), 0.96 (0.87, 1.05), and 1.08 (1.02, 1.14) kPa.L(-1). second for never (n = 482), early transient (n = 236), late-onset (n = 22), and persistent (n = 98) wheezing phenotypes, respectively. Additional analyses were performed for children with atopic and nonatopic mothers separately. Both in children with atopic and nonatopic mothers, children with persistent wheeze had significantly higher interrupter resistance values than children with never and early wheeze. In conclusion, mean interrupter resistance values were higher in children with persistent wheeze as compared with children with never and early transient wheezing phenotypes.
Comparison of the Non‐Nucleoside Reverse Transcriptase Inhibitor Lersivirine with its Pyrazole and Imidazole Isomers

Lersivirine is a potent non‐nucleoside reverse transcriptase inhibitor with exceptional mutant resilience. Here, we compare the pharmacological and pharmacokinetic profile of lersivirine with its pyrazole and imidazole isomers and briefly explore the profile of these series. This work establishes lersivirine as the outstanding molecule in this set.
Sliding Mode Control for Fuzzy Singular Systems With Time Delay Based on Vector Integral Sliding Mode Surface

This article studies the sliding mode control (SMC) of a class of Takagi–Sugeno (T–S) fuzzy singular systems with matched external disturbances. The key advantage of this article is that the input matrices of the considered fuzzy systems could be different, and a novel SMC provided in this article has strong robustness. In this article, systems with delayed state are considered. The time delay is a known constant, and the full state vector is available for feedback. At first, a new sliding mode surface, vector integral sliding mode surface, is proposed. By use of this surface, the stabilization problem for some T–S fuzzy singular systems with different input matrices can be settled. Second, a new SMC law is provided to avoid the state of the considered fuzzy system escaping from every subsliding mode surface. Finally, two examples are provided to verify the validity of the method proposed in this article.
TUNEL assay and SCSA determine different aspects of sperm DNA damage

For the determination of sperm DNA damage, different assays are used. However, no further distinction is made and the literature generally speaks about DNA damage. Thus, this study aimed at comparing the sperm chromatin structure assay (SCSA) and the TUNEL assay. In 79 patients, sperm DNA damage was determined flow cytometrically using the SCSA and the TUNEL assay. Moreover, normal sperm morphology was evaluated according to strict criteria. A statistical comparison of the two methods was performed using standard correlations, Bland and Altman plots, Passing–Bablok regressions and concordance correlation. Results show a significant difference between P‐ and G‐pattern morphology only for the mean channel fluorescence of the SCSA. Spearman’s rank correlations between the different parameters of both assays, SCSA and TUNEL, revealed significant associations between the parameters of the assays. However, when applying Bland and Altman plots, Passing–Bablok regression and concordance correlation results showed that these methods are not comparable. These different techniques determine different aspects of sperm DNA damage, i.e. ‘real’ DNA damage for the TUNEL assay and ‘potential’ DNA damage in terms of susceptibility to DNA denaturation for the SCSA. Thus, one should clearly distinguish between the different assays, not only practically and methodologically but also linguistically.
A Congenital Progressive Ovine Muscular Dystrophy

A congenital progressive myopathy affecting 2% of a flock of Merino sheep involved most of the muscles of the pelvic and pectoral girdles. The vastus intermedius muscle was consistently affected; at 2 years of age 50% of its fibers were replaced by fat and at 5 years almost all. Lesions were bilaterally symmetrical. Usually all components of the quadriceps muscle were involved, but scattered affected fibers were found in most other appendicular muscles. The lesions in the quadriceps muscles resulted in inability to flex the femoro-tibial joint, with consequent difficulty in locomotion, which, under range conditions, resulted in death from inability to forage. Histologically, affected muscles had rounded fibers with central and peripheral sarcoplasmic masses. The fibers contained vesicular nuclei that usually formed rows of up to 15, but occasionally up to 50. In 6-week-old lambs, muscle fibers ranged in diameter from 15-100 μ. No lesion was detected in the peripheral or central nervous system.
From objects to classes: algorithms for optimal object-oriented design

Introduces a novel, axiomatically defined, object-oriented data model called the Demeter kernel model; and secondly, presents abstraction and optimisation algorithms and their relationships for designing classes from objects in the kernel model. The authors analyse several computational problems underlying the class design process, which is divided into two phases; a learning phase and an optimisation phase. This study focuses on approximation algorithms for the optimisation phase and aims to lead to a better understanding and a partial automation of the object-oriented design process. The algorithms and the theory presented have been implemented in the C++Demeter System, a CASE tool for object-oriented design and programming. >
Trajectory tracking with collision avoidance for nonholonomic vehicles with acceleration constraints and limited sensing

Nowadays, autonomously operated nonholonomic vehicles are employed in a wide range of applications, ranging from relatively simple household chores (e.g. carpet vacuuming and lawn mowing) to highly sophisticated assignments (e.g. outer space exploration and combat missions). Each application may require different levels of accuracy and capabilities from the vehicles, yet, all expect the same critical outcome: to safely complete the task while avoiding collisions with obstacles and the environment. Herein, we report on a bounded control law for nonholonomic systems of unicycle-type that satisfactorily drive a vehicle along a desired trajectory while guaranteeing a minimum safe distance from another vehicle or obstacle at all times. The control law is comprised of two parts. The first is a trajectory tracking and set-point stabilization control law that accounts for the vehicle’s kinematic and dynamic constraints (i.e. restrictions on velocity and acceleration). We show that the bounded tracking control law enforces global asymptotic convergence to the desired trajectory and local exponential stability of the full state vector in the case of set-point stabilization. The second part is a real-time avoidance control law that guarantees collision-free transit for the vehicle in noncooperative and cooperative scenarios independently of bounded uncertainties and errors in the obstacles’ detection process. The avoidance control acts locally, meaning that it is only active when an obstacle is close and null when the obstacle is safely away. Moreover, the avoidance control is designed according to the vehicle’s acceleration limits to compensate for lags in the vehicle’s reaction time. The performance of the synthesized control law is then evaluated and validated via simulation and experimental tests.
Demodulation of instantaneous rotational speed of diesel engine based on Hilbert transform

To measure diesel engine rotational speed, special 84-teethed wheel is fixed across the engine output shaft, and magnetoelectric transducer mounted above the wheel. The induced electromotive force between the tooth and the sensor is measured, whose frequency characteristics contains the engine speed information. Engine instantaneous speed is extracted by counting process method and Hilbert demodulation method respectively, and their differences are analyzed. Taking no tooth wheel indexing mismachining tolerance into consideration, the time resolution from the counting process mainly lies on the teeth number. While the number is limited, the result cannot be satisfactory. And its amplitude error can be guaranteed within need only by greater sampling frequency. Comparatively, time resolution of the engine instantaneous speed from the Hilbert methods depends on the sampling frequency, so it is relatively fine. And its error mainly results from the signal processing, avoiding high sampling frequency demand.
The influence of surface hydration on the interfacial electron transfer dynamics from Rhodamine B into SnO2

The influence of surface hydration on the time-scales and mechanisms of interfacial electron transfer from rhodamine B into SnO2 is investigated. We combine molecular dynamics simulations and quantum dynamics propagation of transient electronic excitations to analyze the regulatory role of water molecules affecting the adsorbate-semiconductor interactions and the underlying electronic couplings that determine the electron injection times. The reported results are essential to advance our understanding of interfacial electron transfer dynamics in dye sensitized semiconductor surfaces at the molecule level, including fundamental interactions that affect the efficiency of interfacial electronic processes in dye-sensitized solar cells as well as in a wide range of other technological applications.
SMO Algorithm for Least-Squares SVM Formulations

This article extends the well-known SMO algorithm of support vector machines (SVMs) to least-squares SVM formulations that include LS-SVM classification, kernel ridge regression, and a particular form of regularized kernel Fisher discriminant. The algorithm is shown to be asymptotically convergent. It is also extremely easy to implement. Computational experiments show that the algorithm is fast and scales efficiently (quadratically) as a function of the number of examples.
Functional specificity of the replication fork‐arrest complexes of Bacillus subtilis and Escherichia coli: significant specificity for Tus–Ter functioning in E. coli

The Escherichia coli replication terminator TerB was inserted in its two alternate orientations into a Bacillus subtilis fork‐arrest assay plasmid. After transferring these new plasmids into B. subtilis, which could overproduce the E. coli terminator protein Tus, it was shown that the E. coli Tus–TerB complex could cause polar replication fork arrest, albeit at a very low level, in B. subtilis. A new B. subtilis–E. coli shuttle plasmid was designed to allow the insertion of either the TerI (B. subtilis) or TerB (E. coli) terminator at the same site and in the active orientation in relation to the approaching replication fork generated in either organism. Fork‐arrest assays for both terminator‐containing plasmids replicating in both organisms which also produced saturating levels of either the B. subtilis terminator protein (RTP) or Tus were performed. The efficiency of the Tus–TerB complex in causing fork arrest was much higher in E. coli than in B. subtilis. The efficiency of the B. subtilis RTP–TerI complex was higher in B. subtilis than in E. coli, but the effect was significantly less. Evidently a specificity feature in E. coli operates to enhance appreciably the fork‐arrest efficiency of a Tus–Ter complex. The specificity effect is of less significance for an RTP–Ter complex functioning in B. subtilis.
Evolution of the RALF Gene Family in Plants: Gene Duplication and Selection Patterns

Rapid alkalinization factors (RALFs) are plant small peptides that could induce a rapid pH increase in the medium of plant cell suspension culture and play a critical role in plant development. The evolutionary process of the RALF gene family remains unclear. To obtain details of the phylogeny of these genes, this study characterized RALF genes in Arabidopsis, rice, poplar and maize. Phylogenetic trees, evolutionary patterns and molecular evolutionary rates were used to elucidate the evolutionary process of this gene family. In addition, the different signatures of selection, expression patterns, and subcellular localization of RALFs were also analyzed. We found that the RALF gene family had a rapid birth process after the separation of the eudicot and monocot species about 145 million years ago, that tandem duplication played a dominant role in the expansion of Arabidopsis and rice RALF gene family, and that RALFs were under purifying selection according to estimations of the substitution rates of these genes. We also identified a diverse expression pattern of RALF genes and predominant extracellular localization feature of RALF proteins. Our findings shed light on several key differences in RALF gene family evolution among the plant species, which may provide a scaffold for future functional analysis of this family.
Ultrasmall arrowhead arrayed-waveguide grating with V-shaped bend waveguides

The ultrasmall arrowhead arrayed-waveguide grating (AWG) with integrated waveguide mirrors has been proposed. The v-shaped bend waveguides, using integrated waveguide elliptic mirrors, were applied to the arrayed waveguide to reduce the AWG size. The small footprint leads to a low-cost waveguide device and decreases the phase error resulting from refractive index fluctuations. The eight-channel 40-GHz-spacing arrowhead AWG was fabricated from silica, with a refractive index difference of 0.75%. The size of this arrowhead AWG was 1.3 /spl times/ 11.6 mm, being 1/10 of the size of the conventional one. The insertion loss and the adjacent crosstalk were 8.31 and -28.3 dB, respectively.
Psychometric Testing of Two Chinese-Version Scales on Attitudes Toward and Caregiving Behaviors for End-of-Life Patients and Families

The study purpose was to examine the validities and reliabilities of the Chinese-versions Frommelt Attitudes Toward Care of the Dying Scale (Attitudes Scale) and Caregiving Behaviors Scale for End-of-Life Patients and Families (Behaviors Scale). The scales were tested in a convenience sample of 318 nurses with ≥6 months work experience at three hospitals. Cronbach’s alphas of the Attitudes and Behaviors Scales were . 90 and . 96, respectively. Each scale had Kaiser–Meyer–Olkin index >. 85 and Bartlett’s test of sphericity >4000 (p < .001). Attitudes Scale loaded on three factors: respecting and caring for dying patients and families, avoiding care of the dying, and involving patients and families in end-of-life care. The Behaviors Scale loaded on two factors: supporting dying patients and families, and helping families cope with grief. Factor loadings for both scales were ≥. 49. Both Attitudes and Behaviors Scales are reliable and valid for evaluating nurses’ attitudes and caregiving behaviors for the dying.
Finding Meaning: Antecedents Of Uncertainty in Illness

In this study a portion of the uncertainty in illness model was tested. Antecedents to uncertainty tested were the stimuli frame variables of symptom pattern and event familiarity and the structure provider variables of education, social support, and credible authority. Data were collected on a convenience sample of 61 women with gynecological cancer at the time of major treatment effect. Findings supported the proposed model with an empirically generated revised model presenting the influence of antecedents on specific areas of uncertainty. Divergent paths for reducing uncertainty were found. Social support, credible authority, and event familiarity had the greatest influence on lowering the level of uncertainty. Event familiarity and credible authority were primarily effective in reducing the complexity surrounding treatment and the system of care. Social support functioned to decrease the level of ambiguity concerning the state of the illness. Findings generally support the proposed explanation for uncertainty arousal and have substantive significance in identifying the sources of stimuli leading to uncertainty arousal and modification.
Adaptive Recursive Tessellations (ART) for Geographical Information Systems

Adaptive Recursive Tessellations (ART) is a conceptual and generalized framework for a series of hierarchical tessellation models characterized by a variable decomposition ratio and rectangular cells. ART offers more flexibility in cell size and shape than the quadtree which is constrained by its fixed 1:4 decomposition ratio and square cells. Thus the variable resolution storage characteristic of the hierarchical tessellations can be fully utilized. A data structure for the implementation of the ART, called Adaptive Recursive Run-Encoding (ARRE), is proposed. Then a spatial database management system specially for ART, the Tessellation Manager, is constructed based on the ARRE. Space efficiency analysis of three ART models are conducted using the Tessellation Manager. The result shows that ART models have similar space efficiency with the quadtree model. ART also has many potential applications in GIS and is suitable as a spatial data model for raster GIS.
Gainful utilization of a highly pernicious and worthless weed mimosa pudica for the green synthesis of silver nanoparticles

Green nanoparticle synthesis has been achieved using the extracts of leaves/stem/roots of mimosa (Mimosapudica) as the reducing and capping agent. The study utilizes the highly pernicious and otherwise worthless terrestrial weed mimosa. Nanoparticles were rapidly synthesized at ambient temperature and shape/size control was made possible by controlling the extract: metal proportions. The results of UV-visible spectrophotometric, Fourier transform infrared, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy support the biosynthesis and characterization of the nanoparticles. One of the distinguishing features of the study is that it employs the whole plant unlike most previous studies which are confined to the use of leaves.
Efficacy of Dietary Selenium to Counteract Toxicity of Deoxynivalenol in Growing Broiler Chickens

Faixova Z, S. Faix, R. Bořutova, Ľ. Leng: Effi cacy of Dietary Selenium to Counteract Toxicity of Deoxynivalenol in Growing Broiler Chickens. Acta Vet. Brno 2007, 76: 349-356. The aim of this study was to evaluate the effect of deoxynivalenol on plasma indicators and effi cacy of dietary selenium to counteract toxicity of deoxynivalenol in growing broiler chicks. Three groups of broilers were formed with 14 birds in each group. Three diets included control (0.2 ppm deoxynivalenol, 0.4 mg selenium/kg diet), deoxynivalenol-contaminated (3 ppm deoxynivalenol, 0.4 mg selenium/kg diet) and deoxynivalenol-contaminated (3 ppm deoxynivalenol) plus selenium-enriched yeast (1.4 mg selenium/kg diet). After 6 weeks of feeding all birds were sacrifi ced and blood samples for chemical analyses were collected. Plasma calcium, chloride and alanine aminotransferase activity were signifi cantly elevated and magnesium, total proteins, triglycerides and free glycerol were decreased in chicks fed deoxynivalenol-contaminated diet compared with those fed the control diet. Supplementation of selenium-enriched yeast to the diet reversed plasma levels of calcium, magnesium and alanine aminotransferase activity in chicks induced by dietary deoxynivalenol. Phosphorus, albumin and cholesterol levels and alkaline phosphatase, aspartate aminotransferase and lactate dehydrogenase activities were not affected by diets. The inclusion of selenium to DON-contaminated diet, however, did not completely alleviate toxic effect on protein and lipid metabolism by the liver. Supplementation of selenium-enriched yeast product counteracted most of the plasma indicator alterations caused by deoxynivalenol-contaminated diet in chicks. Deoxynivalenol, chicken, plasma indices, selenium-enriched yeast
