Retro-projected face displays have recently appeared as an alternative to mechanical robot faces, and stand apart by virtue of their flexibility: they are able to present a variety of faces varying in both realism and individual appearance. Here we examine the role of both 3D mask structure and texture image quality on the perception of gender in one such platform, the Mask-bot. In our experime...

Figure 1 shows an example of a light field camera with a pinhole mask in front of the sensor. If we look at the sensor in 1D and assume an total x-resolution of 900 pixels and a Θ resolution of 9, the local x resolution is 100. The disadvantages are therefore a loss in resolution and a loss of light, as most of the light gets blocked by the mask. Therefore, while this model is very clean on a t...

in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

Let R be a regular local ring, K its field of fractions and (V, φ) a quadratic space over R. In the case of R containing a field of characteristic zero we show that if (V, φ)⊗R K is isotropic over K, then (V, φ) is isotropic over R. 1 Characteristic zero case 1.0.1 Theorem (Main). Let R be a regular local ring, K its field of fractions and (V, φ) a quadratic space over R. Suppose R contains a f...

“MASK-NE”-Mask associated Acne, is a common form of acne during COVID-19 pandemic. It type mechanica seen when external factor occludes the skin, leads to irritation, inflammation and starts/aggravates all grades acne. We conducted cross-sectional study among 773 participants, using Self-administered, aim oriented, questionnaire which includes demographic data, related history, duration wearing...

Since the release of COVID-19 epidemic in late December 2020, recommendations issued for personal protection by the World Health Organization and National Health Organizations around the world. The most prominent of which has the use of masks to prevent the spread of the virus. Despite the importance of this solution, many people still resist using the mask. Therefore, this study, by emphasizin...

Wearing a face mask was strongly recommended during the COVID-19 pandemic. The purpose of this study to investigate diversity oral microbiome, abundance each bacterium on inner surface mask, and effects xerostomia microbiota. conducted 55 generally healthy adults (45 women 10 men, mean age 38.18 ± 12.49 years). Unstimulated flow rate (UFR) stimulated (SFR) were measured in whole saliva samples ...

We present the case of a 45-year-old woman with recent onset of dipnea and atrial fibrillation. She was referred to our center for treatment of an associated ventricular septal defect. Echocardiography confirmed the presence of a membranous ventricular septal defect, but also showed signs of constriction. Cardiac computed tomography displayed a severe, diffuse calcified pericarditis. We show th...

STUDY OBJECTIVE Although preoxygenation for emergency airway management is usually performed with nonrebreather face masks or bag-valve-mask devices, some clinicians also deliver supplemental high-flow oxygen by nasal cannula. We aim to measure the efficacy of supplemental nasal cannula oxygen delivery to conventional bag-valve-mask and nonrebreather face mask preoxygenation both with and witho...

the general relatively isotropic mean landsberg metrics contain the general relativelyisotropic landsberg metrics. a class of finsler metrics is given, in which the mentioned two conceptsare equivalent. in this paper, an interpretation of general relatively isotropic mean landsberg metrics isfound by using c-conformal transformations. some necessary conditions for a general relativelyisotropic ...
