Replacement Effects of Sedentary Time on Metabolic Outcomes-The Maastricht Study.

Sedentary time has been associated with detrimental health effects, so in some countries guidelines to reduce sedentary time have been developed. As reducing sedentary time inevitably results in more non-sedentary time, effects of this reduction may depend on the activity with which it is replaced.

A Time-varying Covariate Approach for Survival Analysis of Paediatric Outcomes.

Conventional survival analysis is commonly applied in the analysis of time-to-event data in paediatric studies, where the exposure variables of interest are often treated as time-fixed. However, the values of these exposure variables can vary over time and time-fixed analysis may introduce time-dependent bias.

A new method to reduce the number of time delays in a network.

Time delays may cause dramatic changes to the dynamics of interacting oscillators. Coupled networks of interacting dynamical systems can have unexpected behaviours when the signal between the vertices are time delayed. It has been shown for a very general class of systems that the time delays can be rearranged as long as the total time delay over the constitutive loops of the network is conserved. This fact allows to reduce the number of time delays of the problem without loss of information. There is a the...

A Test of how Australian adults allocate time for physical activity.

The most common reported barrier to physical activity is a lack of sufficient time. Just like most resources in economics are finite, so too is time within a day. We utilized a time-utility model to better understand how people are allocating time for physical activity. Additionally, we tested whether the allocation of physical activity time impacts people's perception of 'lack of time' as a barrier for physical activity or their likelihood of being sufficiently physical active. Australian adults (N = 725 p...

Assessing the Graphical Perception of Time and Speed on 2D+Time Trajectories.

We empirically evaluate the extent to which people perceive non-constant time and speed encoded on 2D paths. In our graphical perception study, we evaluate nine encodings from the literature for both straight and curved paths. Visualizing time and speed information is a challenge when the x and y axes already encode other data dimensions, for example when plotting a trip on a map. This is particularly true in disciplines such as time-geography and movement analytics that often require visualizing spatio-tem...

Time perception, pacing and exercise intensity: Maximal exercise distorts the perception of time.

Currently there are no data examining the impact of exercise on the perception of time which is surprising as optimal competitive performance is dependent on accurate pacing using knowledge of time elapsed.

Real-Time Adaptation to Time-Varying Constraints for Medical Video Communications.

The wider adoption of mobile Health (mHealth) video communication systems in standard clinical practice requires real-time control to provide for adequate levels of clinical video quality to support reliable diagnosis. The latter can only be achieved with real-time adaptation to time-varying wireless networks' state to guarantee clinically acceptable performance throughout the streaming session, while conforming to device capabilities for supporting real-time encoding.

Scale-Limited Lagrange Stability and Finite-Time Synchronization for Memristive Recurrent Neural Networks on Time Scales.

The existed results of Lagrange stability and finite-time synchronization for memristive recurrent neural networks (MRNNs) are scale-free on time evolvement, and some restrictions appear naturally. In this paper, two novel scale-limited comparison principles are established by means of inequality techniques and induction principle on time scales. Then the results concerning Lagrange stability and global finite-time synchronization of MRNNs on time scales are obtained. Scaled-limited Lagrange stability crite...

Wait Time of < 6 and > 18 Months Predicts Hepatocellular Carcinoma Recurrence after Liver Transplantation: Proposing a Wait Time "Sweet Spot".

It has been postulated that short wait time before liver transplant (LT) for hepatocellular carcinoma (HCC) results in the inclusion of tumors with aggressive biology, but prolonged wait time could result in a shift to more aggressive tumor behavior. We therefore test the hypothesis that a wait time "sweet spot" exists with a lower risk for HCC recurrence compared to the other 2 extremes.

As time passes by: Observed motion-speed and psychological time during video playback.

Research shows that psychological time (i.e., the subjective experience and assessment of the passage of time) is malleable and that the central nervous system re-calibrates temporal information in accordance with situational factors so that psychological time flows slower or faster. Observed motion-speed (e.g., the visual perception of a rolling ball) is an important situational factor which influences the production of time estimates. The present study examines previous findings showing that observed slow...

Waiting time to surgery is correlated with an increased risk of serious adverse events during hospital stay in patients with hip-fracture: A cohort study.

Hip fractures are common in the elderly and are associated with a high adverse event and mortality rate. Time to surgery is one of the major modifiable risk factors influencing adverse outcomes in hip-fracture patients. National guidelines and recommendations have been introduced which advocate specific time frames in which surgery should be performed i.e. within 24-48h. These time constraints have been arbitrarily set without being modelled on the linear assumption i.e. that risk increases continually over...

Learning to infer the time of our actions and decisions from their consequences.

Research shows that people infer the time of their actions and decisions from their consequences. We asked how people know how much time to subtract from consequences in order to infer their actions and decisions. They could either subtract a fixed, default, time from consequences, or learn from experience how much time to subtract in each situation. In two experiments, participants' actions were followed by a tone, which was presented either immediately or after a delay. In Experiment 1, participants estim...

Distortion in time perception as a result of concern about appearing biased.

Two experiments illustrate that the perception of a given time duration slows when white participants observe faces of black men, but only if participants are concerned with appearing biased. In Experiment 1 the concern with the appearance of bias is measured as a chronic state using the external motivation to respond without prejudice scale (Plant & Devine, 1998). In Experiment 2 it is manipulated by varying the race of the experimenter (black versus white). Time perception is assessed via a temporal discr...

A Validation Study of the Fitbit One in Daily Life Using Different Time Intervals.

Accelerometer-based wearables can provide the user with real-time feedback through the device's interface and the mobile platforms. Few studies have focused on the minute-by-minute validity of wearables, which is essential for high-quality real-time feedback. This study aims to assess the validity of the Fitbit One compared with the ActiGraph GT3x + for assessing physical activity (i.e., steps, time spent in moderate, vigorous, and moderate-vigorous physical activity) in young adults using traditional time ...

Evaluation of allograft contamination and decontamination at the Treviso Tissue Bank Foundation: A retrospective study of 11,129 tissues.

Microbiological contamination of retrieved tissues has become a very important topic and a critical aspect in the safety of allografts. We have analysed contamination in 11,129 tissues with a longitudinal contamination profile for each individual tissue. More specifically, 10,035 musculoskeletal tissues and 1,094 cardiovascular tissues were retrieved from a total of 763 multi-tissue donors, of whom 105 were heart-beating donors as well as organ donors, while the remaining 658 were non-heart beating donors a...

Fixed-time stability of dynamical systems and fixed-time synchronization of coupled discontinuous neural networks.

In this paper, the fixed-time stability of dynamical systems and the fixed-time synchronization of coupled discontinuous neural networks are investigated under the framework of Filippov solution. Firstly, by means of reduction to absurdity, a theorem of fixed-time stability is established and a high-precision estimation of the settling-time is given. It is shown by theoretic proof that the estimation bound of the settling time given in this paper is less conservative and more accurate compared with the clas...

Prolongation of prothrombin time in the presence of rivaroxaban: is this the only cause?

Rivaroxaban is an oral direct Xa inhibitor that can lead to prolongation of prothrombin time and activated partial thromboplastin time. However, these basic coagulation tests are not specific for the anticoagulant effect of rivaroxaban and other confounding factors should be considered while interpreting the test results. We report a case of a patient on rivaroxaban, where underlying factor VII deficiency led to confusion in the interpretation of prothrombin time results and delayed her surgery.

Periodicity and stability for variable-time impulsive neural networks.

The paper considers a general neural networks model with variable-time impulses. It is shown that each solution of the system intersects with every discontinuous surface exactly once via several new well-proposed assumptions. Moreover, based on the comparison principle, this paper shows that neural networks with variable-time impulse can be reduced to the corresponding neural network with fixed-time impulses under well-selected conditions. Meanwhile, the fixed-time impulsive systems can be regarded as the c...

Calculating Groundwater Response Times for Flow in Heterogeneous Porous Media.

Predicting the amount of time required for a transient groundwater response to take place is a practical question that is of interest in many situations. This time scale is often called the response time. In the groundwater hydrology literature, there are two main methods used to calculate the response time: (1) both the transient and steady-state groundwater flow equations are solved, and the response time is taken to be amount of time required for the transient solution to approach the steady solution wit...

Stability and Change in Posttraumatic Distress: A 7-Year Follow-Up Study of Mothers and Young Children Exposed to Cumulative Trauma.

In situations of cumulative trauma, it is often unclear why some people remain resilient, whereas others experience distress, and how likely these responses are to change over time. To investigate the constancy of responses to cumulative trauma, stability and change in posttraumatic distress and resistance (as defined by no evidence of clinical symptoms) were assessed twice in 140 Israeli children and mothers exposed to continual rocket attacks over approximately 7 years, when the children were 2-4 (Time 1)...

Too Fast or Too Slow? Time and Neuronal Variability in Bipolar Disorder-A Combined Theoretical and Empirical Investigation.

Time is an essential feature in bipolar disorder (BP). Manic and depressed BP patients perceive the speed of time as either too fast or too slow. The present article combines theoretical and empirical approaches to integrate phenomenological, psychological, and neuroscientific accounts of abnormal time perception in BP. Phenomenology distinguishes between perception of inner time, ie, self-time, and outer time, ie, world-time, that desynchronize or dissociate from each other in BP: inner time speed is abnor...

High risk of overdose death following release from prison: Variations in mortality during a 15-year observation period.

The time post-release from prison involves elevated mortality, especially overdose deaths. Variations in overdose mortality both by time since release from prison and time of release has not been sufficiently investigated. Our aims were to estimate and compare overdose death rates at time intervals after prison release and to estimate the effect on overdose death rates over calendar time.

Television Viewing Time and Inflammatory-Related Mortality.

Television (TV) viewing time is associated with increased risk of all-cause, cardiovascular and cancer mortality. While TV time is detrimentally associated with key inflammatory markers, the associations of TV time with other inflammatory-related mortality (with a predominant inflammatory, oxidative or infectious component, but not attributable to cancer or cardiovascular causes), are unknown.

Household chaos as a context for intergenerational transmission of executive functioning.

Executive functioning (EF) may be transmitted across generations such that strengths or deficiencies in parent EF are similarly manifested in the child. The present study examined the contributions of parent EF and impulsivity on adolescent EF, and investigated whether household chaos is an environmental moderator that alters these transmission processes. American adolescents (N = 167, 47% female, 13-14 years old at Time 1) completed behavioral measures of EF and reported household chaos at Time 1 and one...

Working time structure of pediatric nurses in hospital wards representing different referential levels.

Working time is a non-renewable and important element in the management of an organization. The implementation of changes in the structure of working time may be facilitated by the insight into activities undertaken by employees during work. Such an approach plays an important role since the effective use of time improves the quality of care, prevents timewasting and optimizes the use of the full potential of employees, including nurses. The objective of the study was to determine the structure of working t...
