This article investigates the use of a visible light positioning system in an indoor environment to provide three dimensional (3D) high-accuracy solution. The proposed leveraged single light-emitting diode and image sensor at transmitter receiver (Rx) respectively. can retrieve 3D coordinate Rx using combination angle arrival received signal strength (RSS). To mitigate error induced by lens Rx,...

BACKGROUND Device-related infections represent a significant clinical challenge. Once established, these infections prove difficult to treat with existing antibiotic regimens, compromising the health of device recipients, and usually requiring surgical intervention to resolve. OBJECTIVE The purpose of this study was to determine the efficacy of the AIGIS(RX) antibacterial envelope (TyRx Pharm...

OBJECTIVE To study the acute aftereffects of exercise and relaxation, performed alone and in combination, on blood pressure (BP) measured at baseline and during stressful conditions. DESIGN Clinical trial with comparison of groups and repeated measures in each group. SETTING Exercise Hemodynamic Laboratory, University of São Paulo, Brazil. PARTICIPANTS Fourteen normotensive (NT) and 16 es...

The pyrrolocytosine RX-P873, a new broad-spectrum antibiotic in preclinical development, inhibits protein synthesis at the translation step. The aims of this work were to study RX-P873's ability to accumulate in eukaryotic cells, together with its activity against extracellular and intracellular forms of infection by Staphylococcus aureus and Pseudomonas aeruginosa, using a pharmacodynamic appr...

and Hajnal [I] introduced the real function f(a) =inf {.P(G) J ~~i~: ~a}. They asked about the behaviour ofj(rx) as rx tends to infinity. The complete bipartite graph Kn,n shows that f(n)~c ·log n for n~2, but originally it was unknown whether f(a) is bouJ1ded or not. Recently Gyarfas, Koml6s and Szemeredi (2] showed that f(a) ~a ·log a, provided that a>b, where a and bare suitable contants. Ob...

In 2010, the Purdue University College of Pharmacy established the Medication Safety Research Network of Indiana (Rx-SafeNet), the first practice-based research network (PBRN) in Indiana comprised solely of community pharmacies. In the development of Rx-SafeNet and through our early project experiences, we identified several "lessons learned." We share our story and what we learned in an effort...

We report the discovery of a new isolated neutron star candidate, RX J0420.0–5022, showing evidence (4σ) for 22.7 s X-ray pulsations in ROSAT data. NTT observations of the field around the soft X-ray source do not reveal any likely optical counterpart brighter than B = 25.25 implying an X-ray to optical flux ratio of > 10 3.3 and ruling out other possible kinds of X-ray emitters. The X-ray spec...

Recently, multiple-input multiple-output (MIMO) technology has been introduced into magnetic resonant coupling (MRC) enabled wireless power transfer (WPT) systems for concurrent charging of multiple devices. However, impedance mismatching phenomena caused by strong TX-RX, TX-TX, or RX-RX greatly affect the delivered to load (PDL) in practical systems. To solve this issue, we propose an effectiv...

The bipedal spin label Rx is more restricted in its conformation and dynamics than its monopodal counterpart R1. To systematically investigate the utility of the Rx label, we have attempted to comprehensively survey the attachment of Rx to protein secondary structures. We have examined the formation, structure and dynamics of the spin label in relation to the underlying protein in order to dete...

Photofrin-mediated photodynamic therapy (PDT) is used after surgical resection at the University of Pennsylvania to treat the microscopic disease for malignant pleural mesothelioma and to increase survival rate. When Photofrin is exposed to laser light at 630 nm in well-oxygenated tissue, it produces reacted singlet oxygen ([O2]rx) that kills cancer cells. As [O2]rx is imperative to PDT treatme...
