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.

Space-Time Crystal and Space-Time Group.

Crystal structures and the Bloch theorem play a fundamental role in condensed matter physics. We extend the static crystal to the dynamic "space-time" crystal characterized by the general intertwined space-time periodicities in D+1 dimensions, which include both the static crystal and the Floquet crystal as special cases. A new group structure dubbed a "space-time" group is constructed to describe the discrete symmetries of a space-time crystal. Compared to space and magnetic groups, the space-time group is...

Development of an isothermal amplification-based assay for the rapid detection of Cronobacter spp.

Cronobacter spp. is an opportunistic pathogen that is associated with rare but life-threatening neonatal infections resulting from the consumption of contaminated powdered infant formula milk (PIF). In the present study, we developed recombinase polymerase amplification (RPA) and real-time RPA for the detection of Cronobacter spp. in PIF for the first time by targeting the ompA gene. The specificity and sensitivity of the RPA and real-time RPA were validated and the practical applicability of these methods ...

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.

Time allocation and dietary habits in the United States: Time for re-evaluation?

In this non-exhaustive narrative review, time allocation and its relation to dietary habits are discussed. Drawing from reports relying on time use surveys, the amount of time dedicated to cooking and dining is found to be associated with health outcomes such as BMI and cardiovascular risk. Important modifiers include gender, race, ethnicity and household income. Perception of time intensity is also discussed. Individuals who perceive time pressure or strain may be less likely to engage in healthy food rela...

Representation of Time by Hippocampal Neurons.

The hippocampus is involved in episodic memories of events including time and space. Many studies have focused on the neuronal processing mechanisms underlying spatial cognition and representation in the hippocampus; however, the time-related aspects of memories have only recently become the focus of research. In this review, we first introduce recent reports demonstrating the importance of the hippocampus in the perception of time and then present the hippocampal neuronal dynamics for the representation of...

Multiple types of synchronization analysis for discontinuous Cohen-Grossberg neural networks with time-varying delays.

This paper is devoted to the exponential synchronization, finite time synchronization, and fixed-time synchronization of Cohen-Grossberg neural networks (CGNNs) with discontinuous activations and time-varying delays. Discontinuous feedback controller and Novel adaptive feedback controller are designed to realize global exponential synchronization, finite time synchronization and fixed-time synchronization by adjusting the values of the parameters ω in the controller. Furthermore, the settling time of the f...

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...

Correlates of tummy time in infants aged 0-12 months old: A systematic review.

Tummy time, defined as an infant being placed on their stomach whilst they are awake and supervised, has been shown to have a positive effect on infant development and head shape. Tummy time can be influenced by a number of factors. Using a social ecological model, categories of potential variables can be examined to determine their influence on behaviours such as tummy time. The purpose of this systematic review was to examine potential correlates of tummy time in infants from birth to 12 months old.

Time to First-Line ART Failure and Time to Second-Line ART Switch in the IeDEA Pediatric Cohort.

Globally, 49% of the estimated 1.8 million children living with HIV are accessing antiretroviral therapy (ART). There are limited data concerning long-term durability of first-line ART regimens and time to transition to second-line.

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...

Vanishing time in the pursuit of happiness.

Happiness can be conceptualized as a positive affective state or as a goal whose pursuit ironically pulls the pursuer away from achieving it (Mauss, Tamir, Anderson, & Savino in Emotion, 11(4), 807-815, 2011). But how do people think about time during this latter, never-ending pursuit of happiness? The present investigation asks how seeking happiness influences perceptions of time availability. Four studies demonstrated that trait-level happiness seeking (Study 1) as well as direct manipulation of happiness...

For Better or Worse? Couples' Time Together in Encore Adulthood.

This study examined the amount of time married couples share together in a new "encore adult" life course stage around the 50s, 60s, and 70s. Also investigated was the relationship between shared time and experienced well-being for this age group.

Sitting Time and Physical Function in Australian Retirees: An Analysis of Bidirectional Relationships.

There is limited evidence on the directionality of the associations of sitting time with physical function. This study examined the longitudinal associations of sitting time with changes in physical function, and physical function with changes in sitting time.

Evidence of increasing sedentarism in Mexico City during the last decade: Sitting time prevalence, trends, and associations with obesity and diabetes.

Sedentary behaviors such as sitting time are associated with obesity and diabetes independently of total reported physical activity. This study aimed to describe the current sitting time/day prevalence and trends and to examine the association of sitting time with sociodemographic and clinical variables in Mexico City.

Arrow of Time for Continuous Quantum Measurement.

We investigate the statistical arrow of time for a quantum system being monitored by a sequence of measurements. For a continuous qubit measurement example, we demonstrate that time-reversed evolution is always physically possible, provided that the measurement record is also negated. Despite this restoration of dynamical reversibility, a statistical arrow of time emerges, and may be quantified by the log-likelihood difference between forward and backward propagation hypotheses. We then show that such rever...

Fast algorithms for computing phylogenetic divergence time.

The inference of species divergence time is a key step in most phylogenetic studies. Methods have been available for the last ten years to perform the inference, but the performance of the methods does not yet scale well to studies with hundreds of taxa and thousands of DNA base pairs. For example a study of 349 primate taxa was estimated to require over 9 months of processing time. In this work, we present a new algorithm, AncestralAge, that significantly improves the performance of the divergence time pro...

Patterns of Time Use across the Chronic Obstructive Pulmonary Disease Severity Spectrum.

Descriptions of time use patterns in people with chronic obstructive pulmonary disease (COPD) are scarce and the relationship between use-of-time and COPD severity remains unclear. This study aimed to describe a typical day for people with COPD and to explore the differences in time-use patterns across the Body Mass-Index, Airflow Obstruction, Dyspnoea and Exercise Capacity (BODE) index using compositional analyses. Using a cross-sectional design, 141 adults with clinically stable COPD had their demographic...

Distribution and Clinical Determinants of Time-To-Positivity of Blood Cultures in Patients with Neutropenia.

Blood cultures (BC) are essential in the evaluation of neutropenic fever. Modern BC systems have significantly reduced the time-to-positivity (TTP) of BC. This study explores the probability of bacteraemia when BC have remained negative for different periods of time.

Daily time management in children with spina bifida.

Spina bifida (SB) often results in a complex disability and can also cause cognitive dysfunction. No previous study has investigated the ability to adapt to time in children with SB. This ability is crucial for an individual's possibility to develop autonomy in life. The purpose of this study was to investigate whether children aged 10-17 with SB have lower time-processing abilities than typically-developing children, and to describe the profile of time-processing in children with SB.

Defining Accelerometer Nonwear Time to Maximize Detection of Sedentary Time in Youth.

The present study examined various accelerometer nonwear definitions and their impact on detection of sedentary time using different ActiGraph models, filters, and axes.

Joint Models of Longitudinal and Time-to-Event Data with More Than One Event Time Outcome: A Review.

Methodological development and clinical application of joint models of longitudinal and time-to-event outcomes have grown substantially over the past two decades. However, much of this research has concentrated on a single longitudinal outcome and a single event time outcome. In clinical and public health research, patients who are followed up over time may often experience multiple, recurrent, or a succession of clinical events. Models that utilise such multivariate event time outcomes are quite valuable i...
