The aim of this work is to remotely measure heart rate (HR) and respiratory rate (RR) using a video camera from long range (> 50 m). The proposed system is based on imperceptible signals produced from blood circulation, including skin colour variations and head motion. As these signals are not visible to the naked eye and to preserve the signal strength in the video, we used an improved video magnification technique to enhance these invisible signals and detect the physiological activity within the subject...

Sexuality is not an invisible dimension within social work. Social workers are constantly engaged with aspects of sexuality across virtually all practice domains. Indeed, some of the most fundamental and frequent concerns of social workers involve sexual abuse, sexual violence, and HIV and other sexually transmitted infections. However, conversations about healthy sexuality, positive sexuality, or sexual well-being that are well ensconced in many disciplines are all but absent from current social work literature, education, and practice...

Electroencephalography (EEG) is an important clinical tool and frequently used to study the brain-behavior relationship in humans noninvasively. Traditionally, EEG signals are recorded by positioning electrodes on the scalp and keeping them in place with glue, rubber bands, or elastic caps. This setup provides good coverage of the head, but is impractical for EEG acquisition in natural daily-life situations. Here, we propose the transparent EEG concept. Transparent EEG aims for motion tolerant, highly portable, unobtrusive, and near invisible data acquisition with minimum disturbance of a user's daily activities...

For an electrohydrodynamic (EHD) jet, variables such as the direction of the meniscus and the ejection stability need to be analyzed. Thus, the EHD jet should be observed three-dimensionally (3D) because the variables can only be obtained in the 3D field, especially in unstable modes. However, if the 3D field is reconstructed from multi-directional binary images, eliminating reconstruction errors caused by invisible areas is almost impossible, even when using a tomographic technique. To solve this problem, a new 3D reconstruction method including an ellipse estimation was developed in this study...

STUDY DESIGN: A retrospective radiographic study. OBJECTIVE: To investigate the reliability of using magnetic resonance imaging (MRI) to measure thoracic outlet parameters and whether supine MRI could supersede upright x-ray in measuring these parameters. SUMMARY OF BACKGROUND DATA: On x-ray, overlapped soft and bony tissues make sternum contour invisible. Thus, measuring thoracic inlet (TI) alignment on x-ray may be inaccurate. MRI could clearly show anatomy around TI...

We present an image-guided laparoscopic surgical tool (IGLaST) to prevent bleeding. By applying optical frequency domain imaging (OFDI) to a specially designed laparoscopic surgical tool, the inside of fatty tissue can be observed before a resection, and the presence and size of blood vessels can be recognized. The optical sensing module on the IGLaST head has a diameter of less than 390 µm and is moved back and forth by a linear servo actuator in the IGLaST body. We proved the feasibility of IGLaST by in vivo imaging inside the fatty tissue of a porcine model...

Hsin-Yi Li, Yen-Ho Chu
We demonstrated in this work the usefulness of solvate ionic liquids, SIL 3 and SIL 4, for chemoselective detection of amine gases on a quartz crystal microbalance. This detection of gaseous amines was achieved by nucleophilic aromatic addition reactions with super electrophilic SIL 3 or SIL 4 thin-coated on quartz chips. Starting with inexpensive reagents, functional SIL 3 and SIL 4 could be readily synthesized in two short steps with high isolated yield (81% and 77%, respectively). The QCM platform developed in this work is readily applicable and highly sensitive to low molecular weight amine gases: for propylamine gas at 10 Hz decrease in resonance frequency, the sensitivity of detection using SIL 4 was 5...

Dutch national LGBT policies are not bi-inclusive and this study provides suggestions for improvement, based on empirical research. Attention for bisexuality in policy appears simply to pay lip service and to endorse the construction of sexual orientation as a hetero/homo binary. The outcomes of our survey (n = 1449) and in-depth interviews (n = 38) of Dutch same-sex attracted young people suggest that special attention for bisexual people is warranted. Compared to exclusively same-sex attracted participants, the equally both-sex attracted participants scored worse on openness about their sexual attraction, visibility discomfort, perceived acceptance, and suicide attempts...

Personal health records (PHRs) offer tantalising benefits for patients and healthcare providers, including improvements in patient-provider communication, patient empowerment, and access to data and information. A suspicion that disadvantaged patients are less likely to use or benefit from PHRs stimulated a research agenda that included: (a) a literature review; and (b) empirical analysis of eight years' hospital admission and discharge data linked to measures of patient social disadvantage. The results demonstrated an association between disadvantage, increased use of public hospital services and barriers to PHR use...

Harnessing the power of IT solutions in child primary care requires strategic thought at national level, and good health care delivery needs this support. The aim of this study was to investigate whether children's needs are considered in national e-health strategies in Europe. In 2016, a survey was carried out in all 28 European Member States plus 2 European Economic Area countries. Sixteen countries fail to mention children's needs at all. Only eleven of 27 countries mention children and adolescents in their national e-health strategy documents ranging from mere data protection concerns to comprehensive IT approaches for the improvement of child primary care...

The Berlin Declaration is a landmark call to action, which encourages policy makers to take early action to halt the type 2 diabetes epidemic. It emphasizes the need for prevention, early detection, early control, and early access to the right interventions. We believe these four pillars of early action in type 2 diabetes are as relevant to gestational diabetes mellitus (GDM) and action in the latter will impact on the former. Therefore this statement, authored by 21 experts from 14 countries calls for early action in GDM...

OBJECTIVE: Social inequities threaten the health of the global population. A superficial acknowledgement of social justice by nursing's foundational documents may limit the degree to which nurses view injustice as relevant to nursing practice and education. The purpose was to examine conceptualizations of social justice and connections to broader contexts in the most recent editions. DESIGN: Critical discourse analysis examines and uncovers dynamics related to power, language, and inequality within the American Nurses Association's Code of Ethics, Scope and Standards of Practice, and Social Policy Statement...

Jaesuk Choi, Jihun Kim, Jae Youn Hwang, Minkyu Je, Jun-Young Kim, Shin-Yoon Kim
This paper proposes a novel smart surgical navigation system for intramedullary nailing in orthopedic surgery. Using a handle-integrated laser guidance module, the system can target a drill insertion point onto skin, indicating an accurate target position to perpendicularly access an invisible distal hole. The proposed handle-integration-based fixation of the laser guidance module precisely defines the relative position of the module with respect to the distal hole. Consequently, unlike conventional systems, the proposed system can indicate the target insertion point without any help from bulky and costly external position-tracking equipment that is usually required for compensating disturbances generated by external impacts...

Elnaz Shokati, Nosrat Granpayeh, Mohammad Danaeifar
The ultrathin graphene metasurface is proposed as a mantle cloak to achieve wideband tunable scattering reduction around the spherical (three-dimensional) objects. The cloaking shell over the metallic or dielectric sphere is structured by a periodic array of graphene nanodisks that operate at infrared frequencies. By using the polarizability of the graphene nanodisks and equivalent conductivity method, the metasurface reactance is obtained. To achieve the cloaking shell for both dielectric and conducting spheres, the metasurface reactance as a function of nanodisks dimensions, graphene's Fermi energy, and permittivity of the surrounding areas can be tuned from the inductive to capacitive situation...

Recently, several studies have investigated the effectiveness of the ultrasound-guided lumbosacral transforaminal epidural injection. However, the ultrasound-guided S1 transforaminal epidural injection using an out-of-plane approach, which was previously reported, may cause an intestinal injury or intravascular injection because the needle tip tends to be invisible in the out-of-plane approach. In this study, therefore, we report a new method of ultrasound-guided S1 transforaminal epidural injection using the in-plane approach and color Doppler...

BACKGROUND: Digital maps are instrumental in conveying information about environmental hazards geographically. For laypersons, computer-based maps can serve as tools to promote environmental health literacy about invisible traffic-related air pollution and ultrafine particles. Concentrations of these pollutants are higher near major roadways and increasingly linked to adverse health effects. Interactive computer maps provide visualizations that can allow users to build mental models of the spatial distribution of ultrafine particles in a community and learn about the risk of exposure in a geographic context...
