Relationship between religious beliefs and life satisfaction with death anxiety in the elderly

The present study aims to investigate the relationship between religious beliefs and life satisfaction with death anxiety in the elderly. A number of 120 elderly people were selected as the participants using cluster sampling. Arian’s Religiosity Questionnaire, Satisfaction with Life Scale and Collet – Lester’s Fear of Death Scale were used to collect the data. Pearson correlation formula and multiple regression analysis were run to analyze the data. The results showed a negative correlation between religious beliefs and death anxiety as well as between life satisfaction and death anxiety in the elderly. The results of regression analysis revealed that, from among the predictive variables, life satisfaction was the best predictor of death anxiety.
The effects of abomasal infusions of casein or soya-bean-protein isolate on the milk production of dairy cows in mid-lactation

The effects of abomasal infusion of casein or soya-bean-protein isolate (SPI) on milk production were investigated in four Friesian cows in mid-lactation receiving a basal diet of grass silage and barley which supplied energy and protein considerably in excess of requirements for milk production by conventional rationing standards. Three levels of infusion were used for each protein source, the corresponding doses being isonitrogenous for each of the proteins: 100, 220 and 330 g/d for casein and 115, 230 and 345 g/d for SPI. Casein produced much greater effects on the yield of milk and milk constituents than did SPI. On the highest dose of casein, milk yield was increased by 3.5 kg/d, fat output by 15% and protein output by 36%; corresponding values for the highest dose of SPI were 1.6 kg/d, 12% and 13% respectively. Increases in the yield of milk-protein were linear for casein but for SPI there was no increase beyond the first level of infusion. It was calculated that casein infusion had a marked effect on the utilization of energy: the increases in milk production could be explained either by a channelling of an extra 12 MJ metabolizable energy (ME)/d away from body tissue synthesis and into milk synthesis or by an increase in the efficiency of utilization of ME for lactation from 0.50 on the basal diet to 0.58; the measurements made did not allow the two mechanisms to be clearly differentiated.

Decentralized Participation of Flexible Demand in Electricity Markets—Part I: Market Mechanism

In the deregulated power systems setting, the realization of the significant demand flexibility potential should be coupled with its integration in electricity markets. Centralized market mechanisms raise communication, computational and privacy issues while existing dynamic pricing schemes fail to realize the actual value of demand flexibility. In this two-part paper, a novel day-ahead pool market mechanism is proposed, combining the solution optimality of centralized mechanisms with the decentralized demand participation structure of dynamic pricing schemes and based on Lagrangian relaxation (LR) principles. Part I presents the theoretical background, algorithmic approaches and suitable examples to address challenges associated with the application of the mechanism and provides an implementation framework. Non-convexities in reschedulable demand participants' price response and their impacts on the ability of the basic LR structure to reach feasible market clearing solutions are identified and a simple yet effective LR heuristic method is developed to produce both feasible and high quality solutions by limiting the concentrated shift of reschedulable demand to the same low-priced time periods.
The crystal structure of yeast phenylalanine tRNA at 2.0 A resolution: cleavage by Mg(2+) in 15-year old crystals.

We have re-determined the crystal structure of yeast tRNA(Phe) to 2. 0 A resolution using 15 year old crystals. The accuracy of the new structure, due both to higher resolution data and formerly unavailable refinement methods, consolidates the previous structural information, but also reveals novel details. In particular, the water structure around the tightly bound Mg(2+) is now clearly resolved, and hence provides more accurate information on the geometry of the magnesium-binding sites and the role of water molecules in coordinating the metal ions to the tRNA. We have assigned a total of ten magnesium ions and identified a partly conserved geometry for high-affinity Mg(2+ )binding. In the electron density map there is also clear density for a spermine molecule binding in the major groove of the TPsiC arm and also contacting a symmetry-related tRNA molecule. Interestingly, we have also found that two specific regions of the tRNA in the crystals are partially cleaved. The sites of hydrolysis are within the D and anticodon loops in the vicinity of Mg(2+).
Weak C* Hopf symmetry

Weak C* Hopf algebras can act as global symmetries in low-dimensional quantum field theories, when braid group statistics prevents ordinary gr oup symmetries. Charged fields transform linearly in finite multiplets, and the observable s are precisely the gauge invariants. Possibilities to construct field algebras with weak C* Hopf s ymmetry from a given theory of local observables are discussed.
Agnostically learning decision trees

We give a query algorithm for agnostically learning decision trees with respect to the uniform distribution on inputs. Given black-box access to an *arbitrary* binary function f on the n-dimensional hypercube, our algorithm finds a function that agrees with f on almost (within an epsilon fraction) as many inputs as the best size-t decision tree, in time poly(n,t,1ε). This is the first polynomial-time algorithm for learning decision trees in a harsh noise model. We also give a *proper* agnostic learning algorithm for juntas, a sub-class of decision trees, again using membership queries. Conceptually, the present paper parallels recent work towards agnostic learning of halfspaces (Kalai et al, 2005); algorithmically, it is more challenging. The core of our learning algorithm is a procedure to implicitly solve a convex optimization problem over the L1 ball in 2n dimensions using an approximate gradient projection method.
Dendritic Cells Pulsed with Intact Streptococcus pneumoniae Elicit both Protein- and Polysaccharide-specific Immunoglobulin Isotype Responses In Vivo through Distinct Mechanisms

Immature bone marrow–derived myeloid dendritic cells (BMDCs) are induced to undergo phenotypic maturation and secretion of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-12, and IL-10 when pulsed in vitro with intact Streptococcus pneumoniae. After transfer to naive mice, pulsed BMDCs induce immunoglobulin (Ig) isotype responses specific for both protein and polysaccharide pneumococcal antigens, having in common the requirement for viable BMDCs, T cells, and B7-dependent costimulation in the recipient mice. Whereas primary Ig isotype responses to bacterial proteins uniformly require BMDC expression of major histocompatibility complex class II, CD40, and B7, and the secretion of IL-6, but not IL-12, similar requirements for antipolysaccharide Ig responses were only observed for the IgG1 isotype.
Cyclooxygenase-2 and c-erbB-2 Expression in Colorectal Carcinoma Assessed Using Tissue Microarrays

The c-erbB-2 and cyclooxygenase (COX) pathways are involved in the pathogenesis of colorectal carcinoma, but the relationship is not fully understood. This study evaluated the significance of c-erbB-2, COX-2, and Ki-67 protein expression in 185 patients with colorectal carcinoma using tissue microarrays. Only one case expressed c-erbB-2 protein. COX-2 expression was noted in 166 of 176 cases (94.3%), and the Ki-67 expression rate averaged 5.9%. There was no relationship among c-erbB-2, COX-2, and Ki-67 protein expression, and COX-2 protein expression was not related to tumor stage, differentiation, size, depth of invasion, lymphatic or vascular invasion, or patient survival. While the contribution of c-erbB-2 to colorectal carcinogenesis may be of little quantity, COX-2 may be deeply involved in colorectal carcinogenesis.
Characterisation of mucosal and systemic immune responses in rainbow trout (Oncorhynchus mykiss) using surface plasmon resonance.

Mucosal and systemic antibody production in rainbow trout, Oncorhynchus mykiss (Walbaum), was evaluated following different antigen delivery routes. A BIAcore instrument (Pharmacia) allowed direct detection of antibody-antigen interactions by surface plasmon resonance changes. These interactions were measured in real-time without secondary reagents or extraneous labels. Groups of rainbow trout were immunised with a hapten-carrier antigen consisting of fluorescein isothiocyanate (FITC) conjugated to keyhole limpet haemocyanin (KLH) or phosphate buffered saline (PBS) pH 7.2. Antigens were administered intraperitoneally (i.p.) with or without Freund's complete adjuvant (FCA) or peranally (p.a.) directly to the gastrointestinal (GI) tract. Serum and mucosal anti-FITC responses were significantly (P<0.05) higher in FITC-KLH/FCA groups, clearly showing that adjuvant incorporation enhances mucosal as well as sytemic immunity. Antigen uptake and processing in fish immunised p.a. and i.p. without adjuvant was much less efficient and resulted in relatively low levels of serum and mucosal antibody production. Interestingly, mucosal responses in these groups peaked prior to serum responses suggesting possible early stimulation of mucosal defences. Mucosal antibody production in fish receiving FITC-KLH/FCA correlated more closely with serum responses, indicating possible transfer of serum derived antibody to mucosal sites. Mucosal and serum responses were confirmed as immunoglobulin (Ig) by subsequent reactivity with an anti-trout serum IgM monoclonal antibody (1.14) passed over flow cells containing anti-FITC antibodies. Further analysis showed significantly lower (P<0.05) reactivity of early mucus anti-FITC components (4 weeks post-immunisation) to 1.14. Purified serum and mucus Ig from non-immunised fish showed different protein banding patterns by SDS-PAGE under reducing conditions. Immunoblotting with 1.14 also showed weak reactivity to mucus Ig in control fish while reacting strongly to mucus Ig from immunised fish. These data suggest that early mucosal responses in trout may consist of heterogeneous forms of Ig differing in characteristics to serum Ig. BIAcore analysis in this context and as a means of measuring antibody response proved useful, and has the potential to become a valuable new tool in the study of fish immunology.

Reovirus reverse genetics: Incorporation of the CAT gene into the reovirus genome

We have modified the infectious reovirus RNA system so as to generate a reovirus reverse genetics system. The system consists of (i) the plus strands of nine wild-type reovirus genome segments; (ii) transcripts of the genetically modified cDNA form of the tenth genome segment; and (iii) a cell line transformed so as to express the protein normally encoded by the tenth genome segment. In the work described here, we have generated a serotype 3 reovirus into the S2 double-stranded RNA genome segment of which the CAT gene has been cloned. The virus is stable, replicates in cells that have been transformed (so as to express the S2 gene product, protein σ2), and expresses high levels of CAT activity. This technology can be extended to members of the orbivirus and rotavirus genera. This technology provides a powerful system for basic studies of double-stranded RNA virus replication; a nonpathogenic viral vector that replicates to high titers and could be used for clinical applications; and a system for providing nonselectable viral variants (the result of mutations, insertions, and deletions) that could be valuable for the construction of viral vaccine strains against human and animal pathogens.
Sparse Support Recovery with Non-smooth Loss Functions

In this paper, we study the support recovery guarantees of underdetermined sparse regression using the $\ell_1$-norm as a regularizer and a non-smooth loss function for data fidelity. More precisely, we focus in detail on the cases of $\ell_1$ and $\ell_\infty$ losses, and contrast them with the usual $\ell_2$ loss.While these losses are routinely used to account for either sparse ($\ell_1$ loss) or uniform ($\ell_\infty$ loss) noise models, a theoretical analysis of their performance is still lacking. In this article, we extend the existing theory from the smooth $\ell_2$ case to these non-smooth cases. We derive a sharp condition which ensures that the support of the vector to recover is stable to small additive noise in the observations, as long as the loss constraint size is tuned proportionally to the noise level. A distinctive feature of our theory is that it also explains what happens when the support is unstable. While the support is not stable anymore, we identify an "extended support" and show that this extended support is stable to small additive noise. To exemplify the usefulness of our theory, we give a detailed numerical analysis of the support stability/instability of compressed sensing recovery with these different losses. This highlights different parameter regimes, ranging from total support stability to progressively increasing support instability.

Computer Vision and Image Understanding Online Multi-object Tracking via Robust Collaborative Model and Sample Selection

The past decade has witnessed significant progress in object detection and tracking in videos. In this paper, we present a collaborative model between a pre-trained object detector and a number of single-object online trackers within the particle filtering framework. For each frame, we construct an association between detections and trackers, and treat each detected image region as a key sample, for online update, if it is associated to a tracker. We present a motion model that incorporates the associated detections with object dynamics. Furthermore, we propose an effective sample selection scheme to update the appearance model of each tracker. We use discriminative and generative appearance models for the likelihood function and data association, respectively. Experimental results show that the proposed scheme generally outperforms state-of-the-art methods.
Inhibition of caspase activity prevents CD95‐mediated hepatic microvascular perfusion failure and restores Kupffer cell clearance capacity

Using a murine model, we studied the effect of agonistic anti‐CD95 antibodies (aCD95) on sinusoidal lining cells and a potential protection by caspase inhibition. C3H/HeN mice were intravenously administered aCD95 (10 µg/mouse) or unspecific IgG (control) in the presence or absence of the caspase inhibitor z‐VAD‐fmk. Analysis of hepatic microcirculation using intravital fluorescence microscopy revealed severe (P<0.01) sinusoidal perfusion failure and reduced (P<0.05) phagocytic activity of Kupffer cells (KC) within 2 h. Transmission electron micrographs demonstrated loss of integrity of sinusoidal endothelial cells as early as 1 h after aCD95 application, whereas histological manifestation of hepatocellular apoptosis and hemorrhagic necrosis was most pronounced at 6 h. Blocking of caspase activity attenuated (P<0.01) both hepatic microvascular perfusion failure and KC dysfunction. Accordingly, full protection of the liver from apoptotic damage and intact microarchitecture was observed in histological sections after z‐VAD‐fmk treatment. Mortality rate was 40% 6 h after aCD95 administration, whereas all animals survived in the z‐VAD‐fmk group (P<0.05). The activation of caspases through CD95 may primarily lead to damage of sinusoidal endothelial cells and hepatic micro‐vascular perfusion failure. Moreover, reduced phagocytic capacity of KC may contribute to accumulation of toxic metabolites released by dying cells at the local site of inflammation, further aggravating liver injury. —Wanner, G.

Signed Permutation Statistics and Cycle Type

Abstract We derive a multivariate generating function which counts signed permutations by their cycle type and to other descent statistics, analogous to a result of Gessel and Reutenauer [4.5] for (unsigned) permutations. The derivation uses a bijection which is the hyperoctahedral analogue of Gessel's necklace bijection.
Sexually transmitted diseases and sexual lifestyles of long-distance truck drivers: A clinico-epidemiologic study in south India

Our study objective was to determine the prevalence and pattern of sexually transmitted diseases (STDs) and to study sexual lifestyles of long-distance truck drivers and their assistants in south India. For this, a total of 263 truck drivers/assistants were recruited from the highway clinic from October 1999 to March 2001. All of them were sexually active and heterosexual contact was the predominant mode (99.2%). Two-thirds of them had contact with commercial sex workers (CSWs) and roughly 60% admitted alcohol consumption. One hundred and two participants (38.7%) had various STDs. The positivity rates of HIV, VDRL and HBsAg were 15.9%, 13.3% and 21.2% respectively. The higher median age, education less than primary school level, longer duration of occupation, longer duration of each trip and a previous history of genital ulcer disease were significant risk factors for the acquisition of HIV infection.
An integrated theory for improved skill acquisition and retention in the three stages of learning

We introduce an integrated theory of learning and forgetting that has implications for training theory and practice. We begin with a review of skill acquisition research that argues that individuals employ different cognitive mechanisms when learning, which can be reliably associated with three stages of learning. This review leads to our proposed skill retention theory, which recommends a method to increase skill retention when designing systems, covering a range of system design issues, from interface design to training. We conclude with a discussion of how we might optimise skill retention based upon this approach. Specifically, we discuss how we might improve training by better spacing the iterations between training sessions to support proceduralisaion to improve skill retention.
The Role of Collateral and Personal Guarantees in Relationship Lending : Evidence from Japan ’ s Small Business Loan Market

This paper investigates the role of collateral and personal guarantees in small business lending using the unique data set of Japan’s small business loan market. Consistent with conventional theory, collateral is more likely to be pledged by riskier borrowers, implying they may be useful in mitigating debtor moral hazard. Contrary to conventional theory, we find that banks whose claims are either collateralized or personally guaranteed monitor borrowers more frequently. We also find that borrowers who establish long-term relationships with their main banks are more likely to pledge collateral. Our empirical evidence thus suggests that collateral and personal guarantees are complementary to relationship lending. JEL classification number: D82, G21, G30
