Yakov Galutin, Eran Falek, Alina Karabchevsky
A new, composite plasmonic waveguide based electromagnetic cloaking scheme is proposed with Si nano-spacer. Here we show, that the scattering fields of an object located on the cloak do not interact with the evanescent field, resulting in object's invisibility. Finite difference time domain (FDTD) numerical calculations were performed to extract the modal distributions and surface intensities on a composite plasmonic waveguide with a metasurface overlayer. Spatially varying effective permittivity was analytically calculated using transformation optics...

Purpose The purpose of this paper is to argue for the widening of attention in healthcare improvement efforts, to include an awareness of the humanity of people who work in the sector and an appreciation of the part human connection plays in engagement around good quality work. Theoretical frameworks and research approaches which draw on action-based, interpretive and systemic thinking are proposed, as a complement to current practices. Design/methodology/approach The paper describes the early stages of an action research (AR) project, which used the appreciative inquiry "4D" framework to conduct participative inquiry in Hamad Medical Corporation's ambulance service in Qatar, in which staff became co-researchers...

HIV-specific CD8+ T-cell responses limit viral replication in untreated infection. After the initiation of antiretroviral therapy (ART), these responses decay and the infected cell population that remains is commonly considered to be invisible to T-cells. We hypothesized that HIV antigen recognition may persist in ART-treated individuals due to low-level or episodic protein expression. We posited that if persistent recognition were occurring it would be preferentially directed against the early HIV gene products Nef, Tat, and Rev as compared to late gene products, such as Gag, Pol, and Env, which have higher barriers to expression...

The indomitable aspect of HIV-1 infection is not that HIV-1 proviral DNA is integrated into host DNA but that it can also turn itself off, remaining invisible to drug or immune surveillance. Thus, the goals of eradication include ways to precisely excise HIV-1 DNA or wake up the silent HIV-1 provirus and eliminate the infected cells thus identified. Methods to identify and fish out the latently infected cells or to delineate their characteristics are being rapidly developed. In 2016, Baxter et al. (A. E. Baxter, J...

AIM AND OBJECTIVES: To review current literature about nurses' clinical reasoning practices that support safe medication administration. BACKGROUND: The literature about medication administration frequently focuses on avoiding medication errors. Nurses' clinical reasoning used during medication administration to maintain medication safety receives less attention in the literature. As health care professionals, nurses work closely with patients, assessing and intervening to promote mediation safety prior to, during and after medication administration...

Karyotype (KT) aberrations are important prognostic factors for acute myeloid leukemia (AML); however, around 50% of cases present normal results. Single nucleotide polymorphism array can detect chromosomal gains, losses or uniparental disomy that are invisible to KT, thus improving patients' risk assessment. However, when both tests are normal, important driver mutations can be detected by the use of next-generation sequencing (NGS). Fourteen adult patients with AML with normal cytogenetics were investigated by NGS for 19 AML-related genes...

BACKGROUND AND IMPORTANCE: During intramedullary lesion surgery, the lesion site and the posterior median sulcus (PMS) should be accurately identified prior to myelotomy to avoid severe injury of the posterior funiculus. However, intramedullary lesions are fundamentally invisible until the myelotomy is performed. Furthermore, the PMS location is frequently unclear due to lesion-induced swelling or distortion of the spinal cord. Intraoperative indocyanine green videoangiography (ICG-VA) followed by FLOW 800 analysis, which shows vascularization of the spinal parenchyma, may provide a solution for these problems in specific cases...

Barrett's esophagus (BE) is a premalignant condition. The incidence of adenocarcinoma in BE has been reported to be between 0.1-3%. Dysplasia in BE is patchy and extensive biopsy sampling is labor intensive, low yield and does not eliminate the sampling error completely. Volumetric laser endomicroscopy (VLE) is expected to enable endoscopists to do targeted biopsy of dysplastic/cancerous lesions (not visible on white light endoscopy) among patients with BE. We reviewed 7 studies with a total of 62 subjects who had undergone VLE...

This study is to review the emergence of new psychiatrists, scientific rationalization, and popular internalization to reorganize the formation process of modern psychological medicine system. Unlike eugenic psychiatry from the Japanese Colonial Era, the social conditions and contexts forming autonomous system of psychiatry of Korea in the 1960s and 1970s have been concentrated. The discussion approach has been tried to secure two perspectives-treatment and criticism-at the same time and to expand the time and scope of study through the extensive texts such as newspapers, magazines, books, advertisements, and others in the 1960s and 1970s...

CFS toolbox is an open-source collection of MATLAB functions that utilizes PsychToolbox-3 (PTB-3). It is designed to allow a researcher to create and run continuous flash suppression experiments using a variety of experimental parameters (i.e., stimulus types and locations, noise characteristics, and experiment window settings). In a CFS experiment, one of the eyes at a time is presented with a dynamically changing noise pattern, while the other eye is concurrently presented with a static target stimulus, such as a Gabor patch...

This empirical research study examines the experiences of three male-to-female transgender teachers who transitioned genders, in three different decades (1980s, 1990s, 2000s) while actively teaching within Canadian K-12 public schools. I utilize poststructural storylines to explore how these transgender teachers navigated the personal, pedagogical, and political and the survival and transition strategies they developed to become intelligible within their schools. Their storylines illustrate how they developed counter narratives to challenge traditional discourses of trans invisibility, silence, shame, and fear...

Xu Wang, Dongxing Mao, Yong Li
A skin cloak based on the acoustic metasurface made of graded spiral units is proposed and numerically investigated. The presented skin cloak is an acoustical layer consisting of 80 subwavelength-sized unit cells, which provide precise local phase modulation and hence resort the disturbed sound filed in such a way to hide the object to acoustic wave. Numerical simulations show that the suggested skin cloak both work well under normal and small-angled incidences. By taking the advantage of the spiral-typed metasurface, the suggested skin cloak is rather thin with thickness in the order around 1/7 of the wavelength of target frequency, moreover, the intrinsic characteristics of modest dispersion ensure the skin cloak provides remarkable acoustic invisibility in a broad frequency ranging from 2500 Hz to 3600 Hz...

BACKGROUND: The 1974 Safe Drinking Water Act (SDWA) regulates >170,000 public water systems to protect health, but not >13 million private wells. State and local government requirements for private well water testing are rare and inconsistent; the responsibility to ensure water safety remains with individual households. Over the last two decades, geogenic arsenic has emerged as a significant public health concern due to high prevalence in many rural American communities. OBJECTIVES: We build the case for universal screening of private well water quality around arsenic, the most toxic and widespread of common private water contaminants...

This paper describes a novel method for displaying data obtained by three-dimensional medical imaging, by which the position and orientation of a freely movable screen are optically tracked and used in real time to select the current slice from the data set for presentation. With this method, which we call a "freely moving in-situ medical image", the screen and imaged data are registered to a common coordinate system in space external to the user, at adjustable scale, and are available for free exploration...
