Graphics processing units (GPUs) facilitate massive parallelism and high-capacity storage, and thus are suitable for the iterative reconstruction of ultrahigh-resolution micro computed tomography (CT) scans by on-the-fly system matrix (OTFSM) calculation using ordered subsets expectation maximization (OSEM). We propose a finite state automaton (FSA) method that facilitates iterative reconstruction using a heterogeneous multi-GPU platform through parallelizing the matrix calculations derived from a ray tracing system of ordered subsets...

The work environment for building workers in Australia's Northern Territory (NT) is characterised by concerningly high rates of distress and suicide at both a jurisdictional and an industry level. Work-related psychosocial hazards are known antecedents of work-related distress and suicide, and more research is required to understand how these hazards impact workers in this unique building context. This paper examines the unique work environment in the NT building industry by comparing psychosocial hazards in the NT with those in the broader Australian building and construction industry...

Background New establishments frequently face challenges. Pharmacy is integral to healthcare delivery institutes, and inventory management is crucial. The present study investigated the problems faced by the pharmacy of a newly established health institute and proposed relevant solutions to identify drugs needing stringent management control. Methods Responses were collected from seven pharmacists for questionnaires focusing on pharmacy problems and possible solutions. Always better control (ABC), vital essential desirable (VED), and ABC-VED matrix analysis were done on the drugs dispensed during the financial 2022-23...

Our knowledge about the role of fly-in fly-out (FIFO) work-related factors on the well-being of workers across the FIFO work cycle is limited. This study examined the within-person effects of job demand and control on psychological states and health behaviours. The study employed a daily diary design, with 23 FIFO workers in the Australian mining industry completing a daily diary survey for 28 consecutive days across on-shift and off-shift periods. Multilevel analyses showed FIFO workers experienced higher positive affect and enjoyed better sleep quality, but consumed more alcohol, during off-shift days as compared to on-shift days...

This study investigated the seasonal effects that working outdoors had on various parameters in mining industry workers over the course of a work-shift. Workers ( n  = 27) were assessed in summer (33.3 ± 4.2°C, 38 ± 18% RH; n  = 13, age = 46 ± 14 y, BMI = 29.1 ± 5.7 kg/m2 ) and winter (23.6 ± 5.1°C, 39 ± 20% RH; n  = 14, age = 44 ± 12 y, BMI = 31...

Extant literature posits that an individual manages their multiple identities by integrating or separating them to varying degrees. We posit that, rather than managing a single set of identities, an individual may engage different identity structures in different contexts. We use the fly-in, fly-out work context, whereby an employee's home and work are substantially geographically separated, to explore whether different identity structures exist, strategies for managing them, and their effect on employee retention intentions...

This paper aims to design distraction descriptor, elicited through the object variation, to refine the granular knowledge incrementally, using the proposed probability-based incremental update strategy in Incremental Fuzzy-Rough Nearest Neighbour (IncFRNN) technique. Most of the brainprint authentication models were tested in well-controlled environments to minimize the influence of ambient disturbance on the EEG signals. These settings significantly contradict the real-world situations. Thus, making use of the distraction is wiser than eliminating it...

In this study, we specifically visualized DNA molecules at their AT base pairs after in vitro phage ejection. Our AT-specific visualization revealed that either end of the DNA molecule could be ejected first with a nearly 50% probability. This observation challenges the generally accepted theory of Last In First Out (LIFO), which states that the end of the phage λ DNA that enters the capsid last during phage packaging is the first to be ejected, and that both ends of the DNA are unable to move within the extremely condensed phage capsid...

Automated vehicles are expected to greatly boost traffic efficiency. However, how to estimate traffic breakdown probability for the mixed flow of autonomous vehicles and human driven vehicles around ramping areas remains to be answered. In this paper, we propose a stochastic temporal queueing model to reliably depict the queue dynamics of mixed traffic flow at ramping bottlenecks. The new model is a specified Newell's car-following model that allows two kinds of vehicle velocities and first-in-first-out (FIFO) queueing behaviors...

Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors...

OBJECTIVE: Rotation work involves travelling to work in remote areas for a block of time and alternate with spending another block of time at home; such work arrangements have become common in the resources sector. The intermittent absence of workers from the home may adversely affect the health of the workers' families. This study synthesises research on mental and physical health outcomes in partners and children of rotation workers in the resources sector. DESIGN: A systematic review was conducted...

A vehicular Ad-Hoc Network (VANET) is a type of Mobile Ad-Hoc Networks (MANETs) that uses wireless routers inside each vehicle to act as a node. The need for effective solutions to urban traffic congestion issues has increased recently due to the growing number of automobile connections in the car communications system. To ensure a high level of service and avoid unsafe situations brought on by congestion or a broadcast storm, data dissemination in a VANET network requires an effective approach. Effective multi-objective optimization methods are required to tackle this because of the implied competing nature of multi-metric approaches...

The move from open outcry to electronic trading added another responsibility to futures exchanges-that of matching orders between buyers and sellers. Matching systems can affect the level and speed of price discovery, the distribution of revenue, as well as the level of price efficiency of a given market. Whether the matching system is procedurally fair is another important consideration. I argue that while FIFO (First In First Out) is a fair procedure in principle and is perceived as the default matching system, it is not a fair procedure in practice...

Objective: The objective of the study was to explore the CT and ultrasound features and clinical significance of perivascular epithelioid cell tumor (PEComa) of the liver. Methods: Eleven hepatic PEComa patients treated in our hospital were retrospectively analyzed based on the characteristics of the imaging results of the patients, including conventional ultrasound, CDFI, contrast-enhanced ultrasound (CEUS), and contrast-enhanced CT (CECT). Results: CT scans showed that all lesions were hypodense...

BACKGROUND: Fly-In-Fly-Out (FIFO) workers travel to work at isolated locations, and rotate continuous workdays with leave periods at home, and such work practice is common in the offshore oil and gas and onshore mining industry worldwide. The COVID-19 pandemic and accompanying public health actions appear to have had a negative impact on several health-related behaviours among the general population. However, little is known about the impact of the COVID-19 pandemic on the health behaviours of FIFO workers, who have shown higher pre-pandemic rates of risky behaviours than the general population in Australia...

Fly-in fly-out (FIFO) continues to be a fact of life for many men working in the mining industry. The goal of this article is to gain a better understanding of the impacts of FIFO on the overall health of men working in the mining sector and the relationship these men have to seeking help. A qualitative study of 22 men was conducted using a semi-structured interview guide modeled after Torkington et al. Results indicate that men present poor health as a result of workplace-specific performance requirements (long workdays, difficult environmental conditions), being physically far away from their family, and the fact that they do not often seek mental health help...

Sufficient knowledge on the work productivity impact of the health of fly-in fly-out (FIFO) workers in the mining sector in Australia is lacking. This study examined the impact of health and lifestyle behaviours on the work productivity of FIFO workers in the mining industry in Australia. FIFO workers completed an online questionnaire on health and work productivity loss measures. Linear regressions were used to model annual work productivity losses through absenteeism, presenteeism and total productivity loss...

BACKGROUND: Fly-In Fly-Out (FIFO), which entails travelling mostly from the urban areas to stay and work in remote areas for designated periods and travel back home to spend designated days of leave, has become a common work arrangement in the mining sector globally. This study examined the mental and physical health of FIFO workers and described their health-related behaviours during on-and off-shift periods. METHODS: A cross-sectional study was conducted with FIFO workers (N = 216) in the mining industry in Australia who completed an online survey...

The majority of insurance investment funds are derived from policy liability debt funds. It differs from other institutional investors in a number of ways, including investment size, horizon, duration, risk, and so on. However, only a small portion of the extant literature focuses on in-depth and extensive analysis of Insurance Institutional Investors' holdings (IIIs). This study analyses the impact of shareholding by insurance institutions on the value of Shanghai and Shenzhen A-share listed companies in China's capital market...

Active Queue Management (AQM) is recommended by Internet Engineering Task Force to mitigate the bufferbloat phenomenon in the Internet. In this paper, we show the results of comprehensive measurements carried out in our university network, in which a device with an AQM algorithm, designed and programmed for this purpose, was running. The implemented AQM algorithm was based on the dropping function, i.e. arriving packets were dropped randomly, with the probability being a function of the queue length. Several different dropping function forms, proposed in the networking literature, were used, in addition to the classic FIFO queue (no AQM)...
