Conference Paper
Full-text available
Verification of the java Orekit implementation of the Draper Semi-analytical Satellite Theory (DSST) is discussed. The Orekit library for space flight dynamics has been published under the open-source Apache license V2. The DSST is unique among analytical and semi-analytical satellite theories due to the scope of the included force models. However,...

Connectomics has focused primarily on the mapping of synaptic links in the brain; yet it is well established that extrasynaptic volume transmission, especially via monoamines and neuropeptides, is also critical to brain function. Here we present a draft monoamine connectome, along with a partial neuropeptide connectome, for the nematode C. elegans,...

Globally, citizens exist for sustained periods in states of aging-related disease and multimorbidity. Given the urgent and unmet clinical, health care, workforce, and economic needs of aging populations, we need interventions and programs that regenerate tissues and organs and prevent and reverse aging-related damage, disease, and frailty (1). In r...

The preservative effects of low temperature on biological materials have been long recognised, and cryopreservation is now widely used in biomedicine, including in organ transplantation, regenerative medicine and drug discovery. The lack of organs for transplantation constitutes a major medical challenge, stemming largely from the inability to pres...
Article
COVID-19 both creates and complicates public health challenges. Yet the pandemic also provides a unique lens for dissecting complex issues in global health that could benefit society in the long run. In this paper, we discuss the underlying reasons that can help explain the divergent COVID-19 control outcomes between Beijing and Shanghai—two advanc...

Homelessness is seldom a choice. Oftentimes, homelessness reflects the systemic failures that can result from social issues being dismissed or disregarded. Globally, approximately 1.6 billion people lack adequate housing, with 15 million more individuals being evicted on an annual basis. This situation is often profoundly worse in low- and middle-i...

Background Ankylosing spondylitis is a chronic inflammatory disease that is associated with adverse cardiovascular events. This study aimed to determine the relationship between ankylosing spondylitis and the risk of stroke. Methods A systematic literature search in PubMed/MEDLINE, Scopus, and Web of Science were conducted from inception to Decemb...

Although the prevalence of facial recognition-based COVID-19 surveillance tools and techniques, China does not have a facial recognition law to protect its residents’ facial data. Oftentimes, neither the public nor the government knows where people’s facial images are stored, how they have been used, who might use or misuse them, and to what extent...

Just weeks away from the Opening Ceremony of the Beijing 2022 Winter Olympics, the United States, followed by Australia, the United Kingdom, and Canada, has declared a diplomatic boycott of the Games. A diplomatic boycott stipulates that while government officials of these countries will not attend the event, the athletes’ scheduled attendance will...

Background: The dementia epidemic is progressing fast. As the world's older population keeps skyrocketing, the traditional incompetent, time-consuming, and laborious interventions are becoming increasingly insufficient to address dementia patients' health care needs. This is particularly true amid COVID-19. Instead, efficient, cost-effective, and...

These authors contributed equally BACKGROUND Of the medical issues affecting people in microgravity, Space Motion Sickness (SMS) is among the most common and compelling stressors in the first 48-72 hours of spaceflight or any G-transition for that matter. SMS symptoms include cold sweating, nausea, vomiting, and pallor, as well as fatigue and disor...

High dietary sodium and low potassium intake is associated with high blood pressure (BP). The current study aimed to determine if the sodium-to-potassium ratio is more strongly associated with low (130–139/80–89 mm Hg) and high (≥140/90 mm Hg) BP thresholds among US adults than either sodium or potassium alone. A total of 30,776 patients aged ≥20 y...
Conference Paper

A metamaterial inspired planar-patterned microstrip patch antenna, feeding on a Duroid substrate inset bottom ground soft-surface, is presented for ultra-wide band (UWB) applications. The present antenna is configured on a step-edge periodic unit-cell pattern, with a tiny air gap etched on the metal patch and finite ground plane. By employing these...

Background With advances in science and technology, biotechnology is becoming more accessible to people of all demographics. These advances inevitably hold the promise to improve personal and population well-being and welfare substantially. It is paradoxical that while greater access to biotechnology on a population level has many advantages, it ma...

Background: Infectious diseases are dangerous and deadly. As the leading causes of morbidity and mortality in all demographics across the world, infectious diseases carry substantial social, economic, and healthcare costs. Unlike previous global health crises, health experts now have access to more advanced tools and techniques to understand pandem...
Thesis
Full-text available
Connectomics – the study of neural connectivity – is primarily concerned with the mapping and characterisation of wired synaptic links; however, it is well established that long-distance chemical signalling via extrasynaptic volume transmission is also critical to brain function. As these interactions are not visible in the physical structure of th...

Conference Paper
Full-text available
Socio-cultural markers such as attitudes, behaviours, ideas, aspirations and interests were collected and correlated to previously identified social, psychological and quantitative predictors of lifespan. Attitudes to whether a person wanted to live for as long as possible and if so in what condition were also surveyed. The aim of the study was to...
Conference Paper
Full-text available
With an increasing dependence on space systems in all areas of society, the need for accurate and robust Space Situational Awareness (SSA) is paramount. Despite this, software tools have been slow to progress; many systems remain in legacy languages, based on deprecated design principles. The Draper Semianalytic Satellite Theory (DSST) is one such...
Conference Paper
Full-text available
Despite knowing the connectivity of the C. elegans nervous system, its computational properties remain poorly understood. This is especially true for gap junctions, which while forming 890 electrical synapses in C. elegans, have been largely unexplored in terms of processing. Previous research has demonstrated a role for gap junctions in coincidenc...

TMC genes encode a broadly-conserved family of multipass integral membrane proteins in animals that includes eight proteins in humans and mice, one in Drosophila and two in C. elegans. The human TMC1 and TMC2 are deafness genes required for hair cell mechanotransduction; however, the molecular functions of these and other TMC proteins have not been...
Conference Paper
Full-text available
Current methods used to address the problem of autonomous navigation in planetary rovers rely on computationally expensive algorithms and elaborate 3D sensing strategies. This paper presents a low complexity alternative based on an evolved neural controller using continuous-value infrared sensors. A unified framework is presented for developing suc...
Conference Paper
Full-text available
Autonomous navigation and robust obstacle avoidance are prerequisites for the successful operation of a planetary rover. Typical approaches to tackling this problem rely on complex and computationally expensive navigation strategies based upon the creation of 3D maps of the environment. In contrast, this research proposes a simple artificial neural...

After the successful mission of the Mars Pathfinder, in which the first semi-autonomous vehicle explored the Martian surface, other missions to Mars have been launched or are under development. Research on Mars robots provides an ideal test platform for the study of autonomous robotics, for example the ability of robots to navigate efficiently with...
