Enjoyment, intention to use and actual use of a conversational robot by elderly people

In this paper we explore the concept of enjoyment as a possible factor influencing acceptance of robotic technology by elderly people. We describe an experiment with a conversational robot and elderly users (n=30) that incorporates both a test session and a long term user observation. The experiment did confirm the hypothesis that perceived enjoyment has an effect on the intention to use a robotic system. Furthermore, findings show that the general assumption in technology acceptance models that intention to use predicts actual use is also applicable to this specific technology used by elderly people.
Distribution of Vibrio vulnificus in the Chesapeake Bay

Vibrio vulnificus is a potentially lethal human pathogen capable of producing septicemia in susceptible persons. Disease is almost always associated with consumption of seafood, particularly raw oysters, or with exposure of wounds to seawater. An oligonucleotide DNA probe (V. vulnificus alkaline phosphatase-labeled DNA probe [VVAP]), previously shown to be highly specific for V. vulnificus, was used to enumerate this species in environmental samples collected from the Chesapeake Bay between April 1991 and December 1992. Total aerobic, heterotrophic, culturable bacteria were enumerated by plate counts on nonselective medium. The number of V. vulnificus organisms was determined by colony lifts of spread plates for subsequent hybridization with VVAP. V. vulnificus was not detected in any samples collected during February and March (water temperature of < 8 degrees C) but was found in 80% of the water samples collected during May, July, September, and December (water temperature of > 8 degrees C), with concentrations ranging from 3.0 x 10(1) to 2.1 x 10(2)/ml (ca. 8% of the total culturable heterotrophic bacteria). In a multiple regression analysis, increased V. vulnificus concentrations were correlated with lower salinities and with isolation from samples collected closer to the bottom. Isolation from oysters was demonstrable when water temperatures were 7.6 degrees C, with concentrations ranging from 1.0 x 10(3) to 4.7 x 10(4)/g (ca. 12% of total culturable bacteria). In samples collected in May and July, V. vulnificus was identified in seven of seven plankton samples and four of nine sediment samples. Our data demonstrate that V. vulnificus is a widespread and important component of the bacterial population of the Chesapeake Bay, with counts that are comparable to those reported from the Gulf of Mexico.
Planning bridges the intention–behaviour gap: Age makes a difference and strategy use explains why

Objective: This study examines age-differential association patterns between intentions, planning and physical activity in young and middle-aged individuals. The effectiveness of planning to bridge the intention–behaviour gap is assumed to increase with advancing age. We explore the use of behaviour change strategies that include selection, optimisation and compensation (SOC) as underlying mechanisms for age differences. Methods: In N = 265 employees of a national railway company (aged 19–64 years), intentions, planning, SOC strategy use and physical activity were assessed at baseline (Time 1) and again 1 month later (Time 2). Hypotheses were tested in two different path models. Results: Age moderates the extent to which planning mediates the intention–behaviour relation due to an increasing strength of the planning–behaviour link. As a possible psychological mechanism for these age differences, we identified SOC strategy use as a mediator of the age by planning interaction effect on physical activity. Conclusion: These findings suggest differential mechanisms in behaviour regulation in young and middle-aged individuals.
Pilot-assisted Decision Feedback Channel Estimation for OFDM-STTD

Abstract Orthogonal frequency division multiplexing (OFDM) has been attracting much attention for very high-speed data transmission over a frequency-selective fading channel. To improve the performance in a fading channel, some form of antenna diversity technique is necessary. Recently, Alamouti’s space-time coded transmit diversity (STTD) has been gaining a lot of attention for downlink (base-to-mobile) transmissions. For STTD decoding, channel estimation is necessary. In this paper, we propose a pilot-assisted decision feedback channel estimation for STTD decoding in OFDM and evaluate the bit error rate (BER) performance by computer simulation.

Integrative analysis revealed the molecular mechanism underlying RBM10-mediated splicing regulation

RBM10 encodes an RNA binding protein. Mutations in RBM10 are known to cause multiple congenital anomaly syndrome in male humans, the TARP syndrome. However, the molecular function of RBM10 is unknown. Here we used PAR‐CLIP to identify thousands of binding sites of RBM10 and observed significant RBM10–RNA interactions in the vicinity of splice sites. Computational analyses of binding sites as well as loss‐of‐function and gain‐of‐function experiments provided evidence for the function of RBM10 in regulating exon skipping and suggested an underlying mechanistic model, which could be subsequently validated by minigene experiments. Furthermore, we demonstrated the splicing defects in a patient carrying an RBM10 mutation, which could be explained by disrupted function of RBM10 in splicing regulation. Overall, our study established RBM10 as an important regulator of alternative splicing, presented a mechanistic model for RBM10‐mediated splicing regulation and provided a molecular link to understanding a human congenital disorder.
Top Management Team Tenure Diversity and Performance: The Moderating Role of Behavioral Integration

Integrating insights from organizational information processing theory and social categorization theory, we examine how top management team (TMT) tenure diversity affects team performance. We propose a theoretical framework that examines how these two conflicting processes occur simultaneously within diverse TMTs by arguing that TMT tenure variety influences information processing while TMT tenure separation influences the social categorization process. We argue for the presence of nonlinear relationships between tenure variety, tenure separation, and team performance. Furthermore, we propose that these relationships are moderated by the level of TMT behavioral integration. Based on a sample of 357 senior managers from 126 firms in China, we find that both TMT tenure variety and TMT tenure separation have opposing and nonlinear relationships with TMT performance, and the relationship between TMT tenure separation and TMT performance is moderated by the level of TMT behavioral integration. Our results help clarify the conflicting conclusions of previous TMT tenure diversity research. Our findings suggest that the effect of diversity depends on the type of diversity as they affect different processes. Our findings also explain how the opposing effects of both information processing and social categorization can occur simultaneously in the TMT. Furthermore, the effects of both processes are not linear while the level of diversity variety and diversity separation can affect the marginal effects. Finally, TMT behavioral integration processes affect how tenure diversity plays its role in team performance.
On necessary and sufficient conditions in psychiatric explanation.

IT IS WIDELY, if not universally, accepted that psychological events are multidetermined; that there are no simple, unique explanations for most such events. In Psychological research, however, the investigation of several variables at once necessitates large numbers of subjects; * and for practical reasons it is common to explore one variable at a time. Historical cross-sectional studies are common in psychological and epidemiological research. Generally they seek to determine the frequency of occurrence of some crucial event or class of events in the histories of individuals in a particular pathological population in comparison with their frequency in a "normal" population. † Typical examples are: (1) the incidence of psychopathology in the mothers of schizophrenics, (2) the incidence of early parental death in the histories of depressive patients, and (3) the incidence of early illness or trauma in the histories of childhood schizophrenics.

ISO SWS/LWS observations of SN 1987A

We report on observations of SN 1987A with ISO SWS/LWS made 9 - 11 years after the explosion. No emission from the supernova was seen. In particular, the upper limits on the fluxes of [Fe I] 24.05 microns and [Fe II] 25.99 microns on day 3999 are roughly 1.1 Jy and 1.4 Jy, respectively. Assuming a homogeneous distribution of Ti-44 inside 2000 km/s, we have made theoretical models to estimate the mass of ejected Ti-44. Assessing various uncertainties of the model, we obtain an upper limit of 1.5\EE{-4} solar masses. The implications of this are discussed. The LWS data display continuum emission as well as nebular lines of [O I], [C II] and [O III] from neighboring photoexcited regions in the LMC. The [O III] lines indicate an electron density of 120 +/- 75 cm^{-3}, and the continuum can be explained by dust with a temperature of roughly 37 K. A second dust component with approximately 10 K may also be present.
Tear Film Osmolarity in Patients Treated for Glaucoma or Ocular Hypertension

Purpose: To evaluate tear film osmolarity in patients treated with intraocular pressure–lowering medications. Methods: Forty patients treated for glaucoma or ocular hypertension (OHT) were consecutively recruited for the study. Each patient was asked to complete an evaluation of ocular surface disease symptoms, the Ocular Surface Disease Index, and underwent a complete evaluation of the ocular surface including measurement of tear film osmolarity, Schirmer test, tear breakup time (TBUT), and corneal and conjunctival staining. Results: Twenty-four patients (60%) reported ocular surface disease symptoms. Nineteen patients (47.5%) had a tear osmolarity ⩽308 mOsms/L, 11 (27.5%) between 309 and 328 mOsms/L, and 10 (25%) >328 mOsms/L. A tear deficiency was observed in 20 patients (50%). Twenty-seven patients (67.5%) had an abnormal tear quality analyzed with TBUT, and 16 patients (40%) showed positive staining using the Oxford schema. Tear osmolarity was significantly correlated to Ocular Surface Disease Index (r = 0.486; P = 0.002) and TBUT (r = −0.49; P = 0.009). There was a statistically significant correlation between tear osmolarity and the number of drugs (r = 0.409; P = 0.009), the number of instillations (r = 0.405; P = 0.01), and the number of instillations of preserved eye drops (r = 0.629; P < 0.0001). Using the multiple regression method, tear osmolarity remained significantly correlated to the number of instillations of preserved eye drops (P = 0.004). Conclusion: Tear osmolarity was increased in patients treated for glaucoma or OHT, particularly in those using multiple preserved eye drops. The evaluation of the ocular surface of patients treated for glaucoma or OHT may benefit from such analysis, and future trials for new intraocular pressure–lowering eye drops should thus evaluate tear osmolarity.
A soft, amorphous skin that can sense and localize textures

We present a soft, amorphous skin that can sense and localize textures. The skin consists of a series of sensing and computing elements that are networked with their local neighbors and mimic the function of the Pacinian corpuscle in human skin. Each sensor node samples a vibration signal at 1 KHz, transforms the signal into the frequency domain, and classifies up to 15 textures using logistic regression. By measuring the power spectrum of the signal and comparing it with its local neighbors, computing elements can then collaboratively estimate the location of the stimulus. The resulting low-bandwidth information, consisting of the texture probability distribution and its location are then routed to a sink anywhere in the skin in a multi-hop fashion. We describe the design, manufacturing, classification, localization and networking algorithms and experimentally validate the proposed approach. In particular, we demonstrate texture classification with 71% accuracy and centimeter accuracy in localization over an area of approximately three square feet using ten networked sensor nodes.

ESD protection design for mixed-power domains in 90nm CMOS with new efficient power clamp and GND current trigger (GCT) technique

This paper presents an ESD protection design scheme for mixed-power domains in narrow ESD design window with ultra-thin gate oxides. Using a grounded gate (gg)NMOS-based clamp with contact ballast (CTB) layout technique, a factor of 3X area reduction can be achieved for MM protection of a 1.6 nm gate oxide compared to a conventional silicide-block ESD scheme. To expand the design window, a novel ground current trigger (GCT) technique using current sensing circuit between different GND busses is proposed. 7 kV HBM and 550 V MM can be achieved with a 2nd clamp with GCT technique, with the same area as a conventional snapback protection device. The GCT technique is also effective for SCR trigger element as cross clamp.
Complete Problems and Strong Polynomial Reducibilities

A set A is m-reducible to a set B if and only if there is a polynomial-time computable function f such that for all x, $x \in A \Leftrightarrow f(x) \in B$. A set C is m-complete for a class S if $C \in S$ and all sets in S are m-reducible to C. One-reducibility and one-completeness can be defined by requiring f to be one–one. Two sets A and B are p-isomorphic if the function f can be taken one-to-one, onto, and polynomially invertible. In this paper it is shown that all the m-complete sets are one–one complete for ${\operatorname{DTIME}}(2^{\mathcal{O}(n)} )$, ${\operatorname{NTIME}}(2^{\mathcal{O}(n)} )$, and the class of recursively enumerable sets. Further, all the sets complete for ${\operatorname{NTIME}}(2^{\mathcal{O}(n)} )$ under 1–L (or two-way DFA) reductions are p-isomorphic. All the m-complete sets for ${\operatorname{DTIME}}(2^{\mathcal{O}(n)} )$ are p-isomorphic if and only if all the m-complete sets for DTIME($2^{{\text{poly}}} $) are p-isomorphic.
TRF1 promotes parallel pairing of telomeric tracts in vitro.

Human telomeres consist of long arrays of TTAGGG repeats bound to the telomere-specific proteins, TRF1 and TRF2. Here we describe the structure of in vitro complexes formed between telomeric DNA and TRF1 as deduced by electron microscopy. Visualization of TRF1 bound to DNA containing six or 12 tandem TTAGGG repeats revealed a population of DNAs containing a spherical protein complex localized just to the repeats. Mass analysis of the protein complexes suggested binding of TRF1 dimers and tetramers to the TTAGGG repeats. The DNA was not significantly compacted or extended by protein binding. TRF1 formed filamentous structures on longer telomeric repeat arrays (>/=27 repeats) consistent with the presence of an array of bound TRF1 dimers. Unexpectedly, there was a strong propensity for two telomeric tracts to form paired synapses over the TRF1 covered segment. Up to 30% of the TRF1-bound DNAs could be found in a paired configuration with a strong bias for a parallel as contrasted to an antiparallel arrangement. TRF1-induced pairing was confirmed using a ligation assay which detected the formation of DNA multimers dependent on the presence of TRF1 and a 27mer repeat array in the DNA. These findings suggests that this protein may have an architectural role at telomeres. We discuss the possibility that TRF1-dependent changes in the conformation of telomeres are involved in the regulation of telomere length.
The Impact of Confluence on Bone Marrow Mesenchymal Stem (BMMSC) Proliferation and Osteogenic Differentiation

Background: In the field of cellular therapy, the impact of confluence degreeonharvesting or differentiation of BMMSCs and the effect of cell-to-cell contact remain controversial. Therefore, the effect of confluence on properties of BMMSCs was studied and efficiency of confluence-associated osteogenic differentiation was identified. Materials and Methods: The impact of 20, 50, 70, 80 and 100% confluences on proliferation properties of BMMSCs, expression of ERK and p-ERK proteins and glucose consumption rate was studied. Efficiency of confluence-associated osteogenic differentiation was identified by determining calcium deposition, Alizarin Red staining, ALP activity and expression of osteopontin and osteocalcin genes. Results: There was a correlation between confluence % and BMMSCs density. Viability was declined at the lower and higher confluences. The highest CFU-F, Brd-U uptake and population doubling were obtained at 80% confluence. ERK band intensity in 100% confluent BMMSCs was lower compared to other confluences. Bands of p-ERK were highly detectable in 70% and 80% confluences. Glucose consumption rate of 70% and 80% confluences in the last days were higher than 20% and 100% confluences. Although higher osteogenic differentiation was estimated at 80% confluence using calcium deposition, Alizarin Red staining and ALP activity, it was also extended at 100% confluence Osteopontin gene was expressed among all confluences including 100% confluence, while osteocalcin gene was expressed highly in 70% confluent cells. Conclusion: We concluded that the optimum seeding density for maximal expansion and harvesting purposes is 80% confluence and for osteogenic differentiation up to 100% confluence is also acceptable.

Stochastic Annealing for Variational Inference

We empirically evaluate a stochastic annealing strategy for Bayesian posterior optimization with variational inference. Variational inference is a deterministic approach to approximate posterior inference in Bayesian models in which a typically non-convex objective function is locally optimized over the parameters of the approximating distribution. We investigate an annealing method for optimizing this objective with the aim of finding a better local optimal solution and compare with deterministic annealing methods and no annealing. We show that stochastic annealing can provide clear improvement on the GMM and HMM, while performance on LDA tends to favor deterministic annealing methods.
Chern–Schwartz–MacPherson classes for Schubert cells in flag manifolds

We obtain an algorithm computing the Chern–Schwartz–MacPherson (CSM) classes of Schubert cells in a generalized flag manifold $G/B$ . In analogy to how the ordinary divided difference operators act on Schubert classes, each CSM class of a Schubert class is obtained by applying certain Demazure–Lusztig-type operators to the CSM class of a cell of dimension one less. These operators define a representation of the Weyl group on the homology of $G/B$ . By functoriality, we deduce algorithmic expressions for CSM classes of Schubert cells in any flag manifold $G/P$ . We conjecture that the CSM classes of Schubert cells are an effective combination of (homology) Schubert classes, and prove that this is the case in several classes of examples. We also extend our results and conjecture to the torus equivariant setting.
Increased formation of distinct F2 isoprostanes in hypercholesterolemia.

BACKGROUND F2 isoprostanes are stable, free radical-catalyzed products of arachidonic acid that reflect lipid peroxidation in vivo. METHODS AND RESULTS Specific assays were developed by use of mass spectrometry for the F2 isoprostanes iPF2alpha-III and iPF2alpha-VI and arachidonic acid (AA). Urinary excretion of the 2 F2 isoprostanes was significantly increased in hypercholesterolemic patients, whereas substrate AA in urine did not differ between the groups. iPF2alpha-III (pmol/mmol creatinine) was elevated (P<0.0005) in homozygous familial hypercholesterolemic (HFH) patients (85+/-5. 5; n=38) compared with age- and sex-matched normocholesterolemic control subjects (58+/-4.2; n=38), as were levels of iPF2alpha-VI (281+/-22 versus 175+/-13; P<0.0005). Serum cholesterol correlated with urinary iPF2alpha-III (r=0.41; P<0.02) and iPF2alpha-VI (r=0. 39; P<0.03) in HFH patients. Urinary excretion of iPF2alpha-III (81+/-10 versus 59+/-4; P<0.05) and iPF2alpha-VI (195+/-18 versus 149+/-20; P<0.05) was also increased in moderately hypercholesterolemic subjects (n=24) compared with their controls. Urinary excretion of iPF2alpha-III and iPF2alpha-VI was correlated (r=0.57; P<0.0001; n=106). LDL iPF2alpha-III levels (ng/mg arachidonate) were elevated (P<0.01) in HFH patients (0.32+/-0.08) compared with controls (0.09+/-0.02). The concentrations of iPF2-III in LDL and urine were significantly correlated (r=0.42; P<0.05) in HFH patients. CONCLUSIONS Asymptomatic patients with moderate and severe hypercholesterolemia have evidence of oxidant stress in vivo.
