INTRODUCTION: Electric cargo bikes have become popular for transporting goods and people due to their small size and strong carrying capacity. However, the way they perform, handle, and operate safely can be affected by the weight of the cargo, where it is placed on the bike, and the bike's design. METHOD: This paper analyzes the rideability and safety of eight different cargo bikes representing three different design categories, Retrofitted, Long-john, and Long-tail bikes, also considering three different cargo loading locations...

INTRODUCTION: Outdoor activities offer physical and mental health benefits. However, incidents can occur requiring ambulance transport to hospital. This study aimed to describe the epidemiology and severity of traumatic and medical incidents for mountain bikers and hikers transported by ambulance within Western Australia. METHODS: This was a retrospective cohort study of ambulance-transported mountain bikers and hikers within Western Australia from 2015 to 2020...

Humanoid robots that can autonomously operate in diverse environments have the potential to help address labor shortages in factories, assist elderly at home, and colonize new planets. Although classical controllers for humanoid robots have shown impressive results in a number of settings, they are challenging to generalize and adapt to new environments. Here, we present a fully learning-based approach for real-world humanoid locomotion. Our controller is a causal transformer that takes the history of proprioceptive observations and actions as input and predicts the next action...

In this article, we introduce three Bayesian variable selection methods for the quantile autoregressive model with explanatory variables. The Gibbs sampling algorithms are developed for each method by setting different priors. The numerical simulations suggest that the Gibbs sampling algorithms converge fast and Bayesian variable selection methods are reliable. A real example is given to analysis the relationship between the count of total rental bikes and five explanatory variables. Both simulations and data example indicate that the proposed methods are feasible, reliable, and appropriate for analyzing the Bike Sharing data set...

This study aimed to investigate the moderating role of aerobic fitness on the effect of acute exercise on improving executive function from both behavioral and cerebral aspects. Thirty-four young individuals with motor skills were divided into high- and low-fitness groups based on their maximal oxygen uptake. Both groups completed 30 min of moderate-intensity aerobic exercise on a power bike. Executive function tests (Flanker, N-back, More-odd-shifting) were performed before and after exercise and functional near-infrared spectroscopy was used to monitor prefrontal cerebral blood flow changes during the tasks...

BACKGROUND: In Ethiopia, domestic animals and their feces are not properly contained. However, the risk of exposure to zoonotic pathogens is not well documented. This study was conducted to assess animal handling practices and the risk of childhood diarrhea among rural households in northwest Ethiopia. METHODS: This study was done among 403 randomly selected households. Information on animal handling was collected using a questionnaire and spot-check observation...

Urban natural areas provide important ecological services such as biodiversity conservation, as well as opportunities for people to connect with nature and preserve cultural heritage. However, the increasing demand for access to natural areas and the expansion of human recreational activities, such as hiking and biking, pose threats to these ecosystems, especially for animal and plant species, finally resulting in biodiversity loss. This study explores the intricate link between human trampling, plant density, and the morphological and reproductive characteristics of Globularia alypum L...

PURPOSE: With the growing technical options of power transmission and energy-saving options in electric drives, the number of E-bike-related accidents especially in an elderly population has increased. The aim of the current study was to compare if the increased velocity in comparison to conventional bikes translates into different injury patterns in the cranio-cervical and head region. METHODS: A retrospective cohort study was performed in patients admitted to our level one trauma center between 2009 and 2019 after being involved in an accident with either an E-bike, bicycle, or motorcycle and suffered cranio-cervical or traumatic brain injury...

Sustainability is crucial for transforming the food system, addressing environmental and nutrition issues and depends on consumer perceptions and values. This cross-sectional study investigates the relationship between sustainability attitudes, knowledge, and eating behaviours. Nearly half reported high level of knowledge regarding food sustainability while 24% expressed high attitude towards food sustainability. Women reported higher levels of knowledge and attitude towards food sustainability. Logistic regression analyses, adjusted for age, sex, and education, revealed that using public transport, biking, or walking was significantly associated with higher odds of having a more positive overall attitude towards food sustainability (OR = 1...

BACKGROUND: The recommended timing for returning to common activities after cervical spine surgery varies widely among physicians based on training background and personal opinion, without clear guidelines or consensus. The purpose of this study was to analyze spine surgeons' responses about the recommended timing for returning to common activities after different cervical spine procedures. METHODS: This was a survey study including 91 spine surgeons. The participants were asked to complete an anonymous online survey...

The mandible occupies the lowest point on the face. When the lower face is struck by high blows with upward or obliquely directed force, the prominent bone of the face sustains severe damage. When combined with zygomaticomaxillary complex fractures, mandibular fractures, which frequently occur in parasymphysis, present a challenging clinical scenario. This combination often requires a collaborative strategy to ensure a proper diagnosis and all-encompassing care. In this case study, we discussed the alleged trauma case of a 30-year-old male who met with a road traffic accident due to a bike slip at around 8:30 p...

Materials and Methods : Twelve healthy male participants engaged in pedaling exercises on stationary bikes and elliptical machines at speeds of 50 and 70 revolutions per minute (rpm). Knee movement and joint load were assessed using a motion analysis system. Results : The results indicated that elliptical machines induced higher knee joint torque compared to stationary bikes...

There is a relationship between acute bouts of aerobic exercise and cognition in adults, yet the exact nature of this relationship remains unclear. The current pilot study aims to investigate how different modes of cycling (active-assisted cycling vs recumbent cycling) at different moderate-to-vigorous physical activity (MVPA) intensity levels (prescribed 65-70% Heart Rate Max and self-selected 12-13 Rate of Perceived Exertion) modulate neurocognitive, and behavioral markers of cognition in healthy older adults...

This study aimed (1) to investigate the effect of a brief 9-week bike program on preschool motor competence levels and (2) to know the effects of the intervention program on gender. A total of 98 schoolchildren (3.86 ± 0.91 years) from La Coruña (Spain) participated. A pre-post-test quasi-experimental design was used with a control group (CG) made up of 39 students (18 boys) and an experimental group (EG) made up of 59 students (29 boys). Data were gathered using the Movement Assessment Battery for Children-2 (MABC-2)...

Amateur or non-competitive cycling is one of the most popular and growing sports, and the repetitive nature of this sport, combined with a cleat position that is too far forward, often leads to peripheral ischemia or pressure, which can cause pain at the metatarsal level due to the nerve and vascular structures present at this level, according to several authors. This clinical series describes the work done to reduce pain in 21 cyclists who reported foot pain/discomfort exclusively during pedaling. To exclude different causes of pain, other than the position of the cleat, the cyclists received biomechanical assessments using an indoor bike smart trainer and a 2D motion capture system...

INTRODUCTION: In the past decade, China has witnessed a significant surge in the popularity of food delivery apps, with its industry now thrice the size of the U.S, employing approximately 7 million drivers navigating urban landscapes on electric bikes and scooters. Predominantly, the market is governed by two main players: Meituan Dianping (backed by Tencent) and Ele.me (supported by Alibaba). Notably, stress and absenteeism stand out as significant challenges in this service sector, with implications for occupational health that translate into considerable costs for both healthcare systems and companies...

INTRODUCTION: Is Paris a 15-min city, where inhabitants can access essential amenities such as schools and shops with a 15-min walk or bike ride? The concept of a 15-min (more generally, X-minute) city was launched in the French capital and was part of the current mayor's plan in her latest re-election campaign. Yet, its fit with the existing urban structure had not been previously assessed. METHODS: This article combines open map data from a large participatory project and geo-localized socio-economic data from official statistics to fill this gap...

BACKGROUND: In a prior report, we detailed the isolation and engineering of a bispecific killer cell engager, referred to as BiKE:E5C1. The BiKE:E5C1 exhibits high affinity/specificity for the CD16a activating receptor on natural killer (NK) cells and human epidermal growth factor receptor 2 (HER2) on cancer cells. In vitro studies have demonstrated that BiKE:E5C1 can activate the NK cells and induce the killing of HER2+ ovarian and breast cancer cells, surpassing the performance of the best-in-class monoclonal antibody, Trazimera (trastuzumab)...

INTRODUCTION: Electric bicycles, or e-bikes, have become very popular over the past decade. In order to reduce the risk of crashes, it is necessary to understand the contributing factors. While several researchers have examined these elements, few have considered the spatial heterogeneity between crashes and environmental variables, such as Points of Interest (POI). In addition, there is a scarcity of studies comparing the crash-related factors of e-bikes and motorcycles. Despite their differing speed and range capabilities, different POIs also tend to impact area/bandwidths differently because e-bikes cannot cover the same range that motorcycles can...
