Vital signs monitoring is pivotal not only in clinical settings but also home environments. Remote devices, systems, and services are emerging as tracking vital must be performed on a daily basis. Different types of sensors can used to monitor breathing patterns respiratory rate. However, the latter remains least measured sign several scenarios due intrusiveness most adopted sensors. In this paper, we propose an inexpensive, off-the-shelf, contactless measuring system for respiration signals...
Abstract To test and evaluate the second installment of DENTIFY, a virtual reality haptic simulator for Operative Dentistry (OD), on preclinical dental students, by focusing user performance self-assessment. Twenty voluntary unpaid with different background experience, were enrolled this study. After completion an informed consent, demographic questionnaire, being introduced to prototype (on first testing session), three sessions followed (S1, S2, S3). Each session involved following steps:...
Reading room conditions such as illumination, ambient light, human factors and display luminance, play an important role on how radiologists analyze interpret images. Indeed, serious diagnostic errors can appear when observing images through everyday monitors. Typically, these occur whenever professionals are ill-positioned with respect to the or visualize under improper light luminance conditions. In this work, we show that virtual reality assist radiodiagnostics by considerably diminishing...
Introduction: Innovations in 3D spatial technology and augmented reality imaging driven by digital high-tech industrial science have accelerated experimental advances breast cancer the development of medical procedures aimed to reduce invasiveness. Presentation case: A 57-year-old post-menopausal woman presented with screen-detected left-sided cancer. After undergoing all staging pre-operative studies patient was proposed for conservative surgery tumor localization. During surgery, an...
Deep learning (DL) models are very useful for human activity recognition (HAR); these methods present better accuracy HAR when compared to traditional, among other advantages. DL learns from unlabeled data and extracts features raw data, as the case of time-series acceleration. Sliding windows is a feature extraction technique. When used preprocessing it provides an improvement in accuracy, latency, cost processing. The time can be beneficial especially if window size small, but how small...
Abstract Detecting and analysing protein cavities provides significant information about active sites for biological processes (e.g. protein–protein or protein–ligand binding) in molecular graphics modelling. Using the three‐dimensional (3D) structure of a given (i.e. atom types their locations 3D) as retrieved from PDB (Protein Data Bank) file, it is now computationally viable to determine description these cavities. Such correspond pockets, clefts, invaginations, voids, tunnels, channels...
Electric power transmission lines both cause and are impacted by wildfires fuel breaks crucial to mitigate wildfire hazard along in conjunction with these infrastructures. Information about dynamics is for planning maintaining treatments, namely, define their frequency. We sampled mechanically treated line corridors representative of wide variation climate, soil, plant communities Portugal at different times since treatment. Non-destructive methods were used assess ground cover height per...
In darts, the dominant limb typically has an advantage due to superior performance characteristics. However, with training, non-dominant can achieve nearly similar accuracy. Research suggests that left-handed individuals tend have more balanced dexterity between their hands compared right-handed individuals, who show a stronger preference for hand. This may provide slight players. study analysed 12 participants (male and female, aged 20-25 years), including one male rest being right-handed....
Este artigo tem como objetiva demonstrar a importância da inovação não só para o desenvolvimento economia das diversas nações, mas também instrumento de transformação e melhoria qualidade vida no planeta partir tecnológico que reduzam os impactos ambientais, em especial, materiais compósitos desenvolvidos fibras naturais. Essa discussão é justificada pela crescente relevância temática sustentabilidade vivenciadas nas últimas décadas, agravada carência matéria-prima pelas catástrofes...
Multidisciplinary teams are crucial in tailoring cancer care through collaborative decision-making involving several clinical specialties. The inherent complexity of cases, the increasing abundance unstructured textual data, and time restrictions professionals pose significant challenges to team coordination patient care. This creates an opportunity for generative AI technologies, such as LLMs, enhance work. Despite growing interest HCI research explore LLMs healthcare, we have yet...
In this study, a three-dimensional finite element (FE) model based on the specific anatomy of patient presenting femoroacetabular impingement 'cam'-type is developed. The FE meshes structures interest are obtained from arthrographic magnetic resonance images. All soft tissues considered linear elastic and isotropic, bones were assumed rigid. A compression femur acetabular cavity as well flexural movements internal rotations applied. Stresses contact pressures evaluated in patient-specific...
Musculoskeletal models and forward dynamics simulations of human movement often include foot–ground interactions, with the contact forces determined using a constitutive model that depends on material properties kinematics. When soft constraints to kinematics minimum distance between foot planar ground needs be computed. Due their geometric simplicity, considerable number studies have used point–plane elements represent these interacting bodies, but few provided comparisons point other...
The Empathy-Effective Communication hypothesis states the better a speaker can understand their listener's emotions, they transmit information; and listener speaker's apprehend information. Previous emotional sharing systems have managed to create space of understanding between collaborators on remote locations using bio-sensing, but how context face-to-face communication benefit from biofeedback is still be studied. This study introduces new Augmented Reality cue an emotion recognition...
The diaphragm is a muscular membrane separating the abdominal and thoracic cavities, its motion directly linked to respiration.
