Comparison of Water and Lipid Content Measurements Using Diffuse Optical Spectroscopy and MRI in Emulsion Phantoms

We present a quantitative comparison of lipid and water signals obtained from broadband Diffuse Optical Spectroscopy (DOS) and Magnetic Resonance Imaging (MRI). DOS and MRI measurements were performed on an identical set of emulsion phantoms that were composed of different water/soybean oil fractions. Absolute concentrations of water and lipid ranging from 35–94% and 63–6%, respectively were calculated from quantitative broadband near-infrared (NIR) absorption spectra (650–1000 nm). MR images of fat and water were separated using the three-point Dixon technique. DOS and MRI measured water and lipid were highly correlated (R2 = 0.98 and R2 = 0.99, respectively) suggesting that these techniques are complementary over a broad range of physiologically relevant water and lipid values. In addition, comparison of DOS derived concentrations to the MRI “gold standard” technique validates our quantitation approach and permits estimation of DOS accuracy and sensitivity in vivo.
Testing Linear Temporal Logic Formulae on Finite Execution Traces

We present recent work on the development of Java PathExplorer (\JPaXX), a tool for monitoring the execution of Java programs. \JPaX can be used during program testing to gain increased information about program executions, and can potentially furthermore be applied during operation to survey safety critical systems. The tool facilitates automated instrumentation of a program''s byte code, which will then emit events to an observer during its execution. The observer checks the events against user provided high level requirement specifications, for example temporal logic formulae, and against lower level error detection procedures, usually concurrency related such as deadlock and data race algorithms. High level requirement specifications together with their underlying logics are defined in rewriting logic using Maude, and then can either be directly checked using Maude rewriting engine, or be first translated to efficient data structures and then checked in Java.
The Impact of Visual Field Loss on Driving Performance: Evidence From On-Road Driving Assessments

Purpose. The purpose of this study was to investigate the relationship between visual field loss and driving performance as determined by on-road driving assessments. Methods. We reviewed the files of 1350 patients enrolled in a rehabilitation program at the Bloorview MacMillan Rehabilitation Centre, Toronto, Canada. We identified 131 patients with visual field loss who had undergone an on-road driving assessment. These patients had a primary diagnosis of visual impairment or a primary diagnosis of cerebral vascular accident (CVA) with a secondary diagnosis of visual impairment. None of these patients had documentation of neglect, substantial motor or cognitive deficits. We report the data obtained from 13 hemianopics, 7 quadrantanopics, 25 patients with monocular vision, 10 patients with moderate peripheral losses (<135° of horizontal visual field measured at the midline), and 76 patients with mild peripheral losses (between 135° and 186° of horizontal visual field). The on-road assessment consisted of driving in the area surrounding the rehabilitation center, and the outcome was based on performance on a number of tasks commonly encountered in daily driving. For the purposes of this study, the assessment outcomes were classified as safe, unknown, or unsafe. Results. Overall, the extent of visual field loss did not have a significant impact on driving performance (&khgr;2 = 4.37, p = 0.358). However, hemianopia tended to have a worse impact on driving performance than quadrantanopia with a marginally significant result (&khgr;2 = 3.33, p = 0.068). Overall, the location of the visual loss was not significantly related to driving fitness (&khgr;2 = 1.05, p = 0.30). However, localized defects in the left hemifield (&khgr;2 = 9.561, p = 0.002) and diffuse visual loss in the right hemifield (&khgr;2 = 10.395, p = 0.001) seemed to be associated with driving impairments. A large proportion of monocular drivers were safe drivers and the location of their deficit had no significant impact. Conclusions. Although the extent of visual field defects appears to be related to driving performance as determined by an on-road driving assessment, large individual differences were observed. This highlights the need for individualized on-road assessments for patients with visual field defects.
Tetrahedral Mesh Construction for Unit Tangent Bundle over Genus-Zero Surfaces

Unit tangent bundle of a surface carries various information of tangent vector fields on that surface. For 2-spheres (i.e. genus-zero closed surfaces), the unit tangent bundle is a closed 3-manifold that has non-trivial topology and cannot be embedded in R. Therefore it cannot be constructed by existing mesh generation algorithms directly. This work aims at the first discrete construction of unit tangent bundles over 2-spheres using tetrahedral meshes. We propose a two-stage algorithm for the construction, which starts from constructing two local bundles and then combines them into a global bundle.
Existential Resistance to Life: Ambivalence, Avoidance & Control

We use the term existential embrace of life for being fully alive, and existential resistance to life for any self-sabotage that denies and thwarts that potential. In this article, we survey three specific forms that resistance to life may take: ambivalence, avoidance and control. We correlate this conceptualization to current attachment theory and affect regulation theory principles; we apply this conceptualization earlier in life than others have suggested, to the prenatal and pre-existence realms, as well as later in life to include the dying process; and we indicate some practical applications of this conceptualization in psychotherapy. We conceptualize resistance to life as an imbalance between Eros (libido energy of attraction and openness to life and growth) and Thanatos (mortido energy of withdrawal, disintegration, and resistance to life and growth). Three primary defensive strategies exist to resist life rather than fully embrace it: (1) avoidance, the dismissing strategy of compulsive self-reliance, denial and inhibition to deal with one's source of anxiety, i.e., fear of loss of connection or abandonment. In avoidance, one sidesteps life through denial of the libido and mortido drives. The opposite of avoidance is intrusive over-involvement. The synthesis of the two is "unboundaried radical connectedness. " (2) ambivalence, the strategy of creating distractions to re-direct one's attention away from the source of anxiety, i.e., fear of annihilation or engulfment (loss of self). When there is impasse in the struggle between libido and mortido, when neither gains advantage, then movement ceases and paralysis sets in: stalemate. In stalemate, the battle rages on, usurping all available energy. The opposite of ambivalence is a rigid intolerance for ambiguity, nuance or paradox. The synthesis of the two is "passionate commitment in the face of ambiguity. " (3) control, the strategy of regulating internal distress, i.e., the loss of order or the chaos of abandonment, by controlling the perceived source in the outside world in defiance of libido and mortido energies. He desperately seeks physical closeness while trying to create mental distance. The frustration inherent in attempting to both obtain comfort and avoid vulnerability, leads to high levels of stress. The opposite of control is abdication. The synthesis of the two is "ego resiliency. "
A case study : How do Japanese learners of English learn to use acoustic cues to differentiate stressed and unstressed syllables in pronunciation training? (荻内勝之教授退任記念号)

As part of a case study of two adult Japanese learners of English, the present study investigated how they learned to use acoustic cues to differentiate English stressed and unstressed syllables through a pronunciation training program. The acoustic cues included F0, intensity, duration and vowel quality (F2-F1). They received pronunciation training focused on English syllable structure, word and sentence stress, consonants and vowels, coupled with reading and speaking practice with special attention to prosody. The results showed that the Japanese learners were able to learn to use F0 and intensity as the acoustic cues, but that it was much more difficult to learn to use duration and vowel quality. Possible accounts of the results and implications for teaching pronunciation are discussed. key words; pronunciation training, nonnative speech production, prosody, pitch, stress
Light-dependent expression of flg22-induced defense genes in Arabidopsis

Chloroplasts have been reported to generate retrograde immune signals that activate defense gene expression in the nucleus. However, the roles of light and photosynthesis in plant immunity remain largely elusive. In this study, we evaluated the effects of light on the expression of defense genes induced by flg22, a peptide derived from bacterial flagellins which acts as a potent elicitor in plants. Whole-transcriptome analysis of flg22-treated Arabidopsis thaliana seedlings under light and dark conditions for 30 min revealed that a number of (30%) genes strongly induced by flg22 (>4.0) require light for their rapid expression, whereas flg22-repressed genes include a significant number of genes that are down-regulated by light. Furthermore, light is responsible for the flg22-induced accumulation of salicylic acid (SA), indicating that light is indispensable for basal defense responses in plants. To elucidate the role of photosynthesis in defense, we further examined flg22-induced defense gene expression in the presence of specific inhibitors of photosynthetic electron transport: 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) and 2,5-dibromo-3-methyl-6-isopropyl-benzoquinone (DBMIB). Light-dependent expression of defense genes was largely suppressed by DBMIB, but only partially suppressed by DCMU. These findings suggest that photosynthetic electron flow plays a role in controlling the light-dependent expression of flg22-inducible defense genes.
What Is an Artificial Muscle? A Systemic Approach.

Artificial muscles define a large category of actuators we propose to analyze in a systemic framework by considering any artificial muscle as an open-loop stable system for any output which represents an artificial muscle dimension resulting from its “contraction”, understood in a broad meaning. This approach makes it possible to distinguish the artificial muscle from other actuators and to specify an original model for a linear artificial muscle, according to the theory of linear systems. Such a linear artificial muscle concept exhibits a constant stiffness independent on its control value. It is shown that a biomimetic actuator, made of two antagonist artificial muscles, requires that artificial muscle static characteristic, even in its most simplified form, is non-linear in the meaning of systems theory, to make possible the control of both actuator position and stiffness. However, we also attempt to show that a linear viscous damping can be a practical way for the dynamic behavior of the artificial muscle to be in relatively good accordance with the so-called Hill curve, interpreted as the dynamic characteristic linking the maximum contraction velocity of the artificial muscle to varying loads lifted against gravity.
Low power analysis in single stage source coupled VCO with AVL technique using nanoscale CMOS technology

The voltage controlled oscillator (VCO) is the core factor of Phase locked loop (PLL) oscillation frequency synthesizes, which is mainly used in modern electronics information processing systems. Multi stages VCO ring provide less oscillation frequency and high phase noise, so the single-stage source overcomes these problems. This paper presents a comparison between leakage power Reduction techniques AVL (AVLG & AVLS) assuming static and dynamic power consumption. The simulation results have reported that static power (1.35pW), dynamic power (0.74nW) and phase noise (-42.29dBc/Hz) improve using AVLG technique in nanoscale measurement with supply voltage varying from (0.7V to 1.2V).
A Theoretical Study of Religious Psychology and Its Application in Moral Education

In dealing with real-life religion the dimensions cannot be isolated from one another, so when we are studying the experimental dimension, looking at the psychological components of belief and behavior, we must take seriously into consideration the myths and ethics that shape people's lives. Morality is an important part of social development in people's lives. This study aims at understanding and analyzing literature of the psychology of religions and generalizing the implications of the psychology of religions and its application in moral education. Thus, the systemic and complex integration of the thought of religious psychology for the moral education of the students will help teachers understand the thought of religious psychology. It will also improve moral instruction and design effective moral teaching methods, which are based on the religious psychology. Therefore, teachers' work is to design effective teaching that can be conducive to later teaching of the religious education or moral education in teaching environment.
Premature Aging of T cells Is Associated With Faster HIV-1 Disease Progression

Objective:To determine if untreated HIV-1 infection and progression is associated with premature aging of memory CD8+ and CD4+ T cells and naive CD4+ T cells. Methods:Twenty HIV-1-infected fast progressors and 40 slow progressors were included in our study, using risk set sampling. The expression of cell surface markers reflecting the differentiation stages of lymphocytes was measured using flow cytometry analyses performed on cryopreserved peripheral blood mononuclear cells. Results:We found that HIV-1 disease progression is associated with a decreased CD28 median florescence intensity on CD4+ and CD8+ T cells; an increased proportion of intermediate- and late-differentiated CD8+ T cells and a decreased CD31 median florescence intensity on naive CD4+ T cells of recent thymic origin. A selective depletion of peripherally expanded naive CD4+ T cells was found to be associated with HIV-1 infection but not with HIV-1 disease progression. Conclusions:The overall change during HIV-1 infection and progression is associated with a shift in the T-cell population toward an aged conformation, which may be further compromised by impaired renewal of the less-differentiated CD4+ T-cell population. Our results suggest that HIV-1 infection induces an accelerated aging of T lymphocytes, which is associated with the clinical progression to AIDS and death.
Vocal Control Neuron Incorporation Decreases with Age in the Adult Zebra Finch

In adult male zebra finches, high vocal center (HVC) neurons continuously die and are replaced. Many of these cells are projection neurons that form part of the efferent pathway controlling learned song production. Although it is known that HVC receives new neurons well into adulthood, it is unknown whether this occurs at a constant rate or declines with adult age. We used [3H]thymidine to label new HVC neurons in male zebra finches that were 3–36 months of age. Birds were killed 4 months after 3H injections to measure the long-term incorporation of new HVC neurons. HVC neurons projecting to the robust nucleus of the archistriatum (HVC-RA) were retrogradely labeled with Fluoro-Gold 4 d before death. We found a dramatic age-related decline in the number of 3H-labeled HVC-RA neurons present 4 months after cell birth dating. A similar decline in new HVC neurons was found as soon as 1 month after their formation. These results indicate that the production or early survival of adult-formed neurons decreases with age. HVC volume and total neuron number did not change with bird age, suggesting that the age-related decrease in new neuron addition was balanced by increased survivorship of neurons incorporated previously. Reliance of song structure on auditory feedback also wanes with age. We propose that with aging, fewer new cells are added as the numbers of functionally appropriate cells increase, a process that may be linked to age-related increases in motor program stability.
Impact of Estrogen Deprivation on Gene Expression Profiles of Normal Postmenopausal Breast Tissue In vivo

Aromatase inhibitors play a key role in the clinical management of hormone receptor–positive breast cancer and have potential utility as chemopreventive agents. Further understanding of the molecular effects of estrogen and its deprivation in normal breast tissue may allow the development of biomarkers of risk of breast cancer and help to predict the value of chemoprevention with aromatase inhibitors. Core biopsies of normal breast tissue were taken before and after letrozole treatment from postmenopausal women in the LITMaS pilot prevention study. RNA was extracted from these samples and used for cDNA microarray analysis. Gene expression changes induced by letrozole treatment were much less extensive than observed in estrogen receptor–positive malignant tissue; however, overall, they correlated to a highly significant degree (ρ = 0.511; P < 10−20). As well as some classically estrogen-associated genes, many genes associated with extracellular matrix remodeling were affected by estrogen deprivation in the normal breast in vivo. These data indicate for the first time that gene expression of normal breast tissue remains dependent on endogenous estrogens after the menopause. The modest degree of gene change suggests that intermediate markers of chemoprevention may be difficult to identify. (Cancer Epidemiol Biomarkers Prev 2008;17(4):855–63)

Investigating Stability and Linearity of a German M1 Money Demand Function

Starting from a linear error correction model (ECM) the stability and linearity of a German M1 money demand function are investigated, applying smooth transition regression techniques. Using seasonally unadjusted quarterly data from 1961(1) to 1990(2) it is found that the money demand equation considered is both linear and stable. After extending the sampling period until 1995(4) a clear structural instability due to the monetary unification on 1 July 1990 is found and subsequently modelled. A non-linear specification for the extended period is presented and discussed.

Finally a critical evaluation is offered of the application of attachment theory to explain the development of the manifestations.
Single-server aggregation of a re-entrant flow line

On-time delivery performance of a semiconductor manufacturing system depends on the cycle time distribution of lots produced in the manufacturing network. A detailed simulation model of the manufacturing system that can predict the cycle time distribution may be helpful in performance improvement activities, but requires considerable development and maintenance effort. To reduce development and maintenance effort, an aggregate model has recently been developed that is a lumped-parameter representation of a manufacturing workstation. The lumped-parameters are directly determined from arrival and departure events measured at the workstation in operation. In this paper, we investigate under which conditions the previously developed aggregate model can be used to model a re-entrant flow line of workstations, motivated by semiconductor manufacturing. We find that the range of throughput levels for which accurate cycle time predictions are obtained decreases for increasing network size.
Minimal Camera Networks for 3D Image Based Modeling of Cultural Heritage Objects

3D modeling of cultural heritage objects like artifacts, statues and buildings is nowadays an important tool for virtual museums, preservation and restoration. In this paper, we introduce a method to automatically design a minimal imaging network for the 3D modeling of cultural heritage objects. This becomes important for reducing the image capture time and processing when documenting large and complex sites. Moreover, such a minimal camera network design is desirable for imaging non-digitally documented artifacts in museums and other archeological sites to avoid disturbing the visitors for a long time and/or moving delicate precious objects to complete the documentation task. The developed method is tested on the Iraqi famous statue “Lamassu”. Lamassu is a human-headed winged bull of over 4.25 m in height from the era of Ashurnasirpal II (883–859 BC). Close-range photogrammetry is used for the 3D modeling task where a dense ordered imaging network of 45 high resolution images were captured around Lamassu with an object sample distance of 1 mm. These images constitute a dense network and the aim of our study was to apply our method to reduce the number of images for the 3D modeling and at the same time preserve pre-defined point accuracy. Temporary control points were fixed evenly on the body of Lamassu and measured by using a total station for the external validation and scaling purpose. Two network filtering methods are implemented and three different software packages are used to investigate the efficiency of the image orientation and modeling of the statue in the filtered (reduced) image networks. Internal and external validation results prove that minimal image networks can provide highly accurate records and efficiency in terms of visualization, completeness, processing time (>60% reduction) and the final accuracy of 1 mm.
