For a finite connected graph X , we consider the graph RX obtained from X by associating a new vertex to every edge of X and joining by edges the extremities of each edge of X to the corresponding new vertex. We express the spectrum of the Laplace operator on RX as a function of the corresponding spectrum on X . As a corollary, we show that X is a complete graph if and only if λ1(RX) > 1 2 . We...
We present aHubble Space TelescopeAdvanced Camera for Surveys (ACS)weak-lensing study of RX J0849+ 4452 andRX J0848+4453, the twomost distant (at z 1⁄4 1:26 and 1.27, respectively) clusters yet measuredwithweak lensing. The two clusters are separated by 40 from each other and appear to form a supercluster in the Lynx field. Using our deep ACS i775 and z850 imaging, we detected weak-lensing sign...
It is difficult to construct a control group for trials of adjuvant therapy (Rx) of prostate cancer after radical prostatectomy (RP) due to ethical issues and patient acceptance. We utilized 8 curve-fitting models to estimate the time to 60%, 65%, … 95% chance of progression free survival (PFS) based on the data derived from Kattan post-RP nomogram. The 8 models were systematically applied to a...
The evolution of the crystallographic texture in lowcarbon steels from a deformed state to a full recrystallization (RX) state upon annealing is an issue with both academic and practical importance.1–4) Normally, the dominant components in the cold-rolled (CR) texture, {hkl}<110> , vanish after RX. Conversely, the RX texture, consisting of varying intensities of {001}, {111} and {011}...
Idea: E [∼Ra &∼Ba] confirms H [(∀x)(Rx ⊃ Bx)] relative to >, but E doesn’t confirm H relative to some background K ≠ >. Question: Which K ≠ >? Answer: K = ∼Ra. Idea: If you already know that ∼Ra, then observing a’s color won’t tell you anything about the color of ravens. Distinguish the following two claims: (PC) ∼Ra &∼Ba confirms (∀x)(Rx ⊃ Bx), relative to >. (PC*) ∼Ra &∼Ba confirms (∀x)(Rx ⊃ ...
The objective of this study was to compare effects of RX-871024, a compound with imidazoline structure, and the sulfonylurea glibenclamide, representatives of two groups of ATP-dependent potassium channel (KATP) blockers, on insulin secretion and cytoplasmic free calcium concentration ([Ca2+]i). Furthermore, we studied the interaction of the compounds on these two parameters. The experiments we...
We present a high-resolution multi-frequency study of the Small Magellanic Cloud (SMC) region around the X-ray pulsar AX J0105-722. From ROSAT PSPC images we resolve this source into several X-ray sources. We combine X-ray, radio-continuum and optical data to identify the sources: for RX J0105.1-7211 we propose an emission line star from the catalogue of Meyssonier & Azzopardi (1993) in the X-r...
Previous work on the subclones within Escherichia coli ST131 predominantly involved isolates from Western countries. This study assessed the prevalence and antimicrobial resistance attributed to this clonal group. A total of 340 consecutive, non-duplicated urinary E. coli isolates originating from four clinical laboratories in Hong Kong in 2013 were tested. ST131 prevalence among the total isol...
Hyperspectral images have been used in anomaly and change detection applications such as search and rescue operations where it is critical to have fast detection. However, conventional Reed-Xiaoli (RX) algorithm [6] took about 600 seconds using a PC to finish the processing of an 800x1024 hyperspectral image with 10 bands. This is not acceptable for real-time applications. A more recent algorit...
Abstract Background Colorectal malignant cells (CRC) are one of the world’s main causes cancer mortality and morbidity. Notwithstanding plenty anti-CRC therapeutics, its prognosis remains not selective owing to resistance these therapeutics. Raloxifene (RX), a medication firstly used treat osteoporosis, was recently licenced for prevention CRC. Unfortunately, due resistance, many RX-based thera...
