Let $$\Gamma =(K_{n},H^-)$$ be a signed complete graph whose negative edges induce subgraph H. The index of $$\Gamma$$ is the largest eigenvalue its adjacency matrix. In this paper, we study when H unicyclic graph. We show that among all graphs order $$n>5$$ k and maximizes index, triangle with remaining vertices being pendant at same vertex triangle.

background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident.  rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...

SmartRoadSense is a crowdsensing project aimed at monitoring the conditions of the road surface. Using the sensors of a smartphone, SmartRoadSense monitors the vertical accelerations inside a vehicle traveling the road and extracts a roughness index conveying information about the road conditions. The roughness index and the smartphone GPS data are periodically sent to a central server where th...

Gamma gap is the difference in total serum proteins and albumin and an elevated gamma gap is related to infections, malignancy, and rheumatic diseases. An elevated gamma gap is also associated with higher mortality due to the correlation with inflammatory status. The study aimed to utilize mid-arm muscle circumference (MAMC) to assist in predicting all-cause mortality, cancer mortality, and car...

Oligoclonal bands were identified in electropherograms of cerebrospinal fluid, and the "gamma-protein index" was concurrently calculated from the same strip. For the index, an upper limit of normal of 0.66 was established. We compared results with the clinical diagnosis in 69 patients with multiple sclerosis and 48 control patients with other diseases. Sensitivity, specificity, and positive pre...

We present here a new calculation of the gamma-ray spectrum from pp → π in the Galactic ridge environment. The calculation includes the diffractive pp interaction and incorporates the Feynman scaling violation for the first time. Galactic diffuse gamma-rays come, predominantly, from π → γγ in the sub-GeV to multi-GeV range. Hunter et al. found, however, an excess in the GeV range (“GeV Excess”)...

A nilpotent Cantor action is a minimal equicontinuous $\Phi \colon \Gamma \times \mathfrak {X} \to {X}$ on space $\mathfrak {X}$, where $\Gamma$ contains finitely-generated subgroup $\Gamma _0 \subset \Gamma$ of finite index. In this note, we show that these actions are distinguished among general actions: any effective finitely generated group space, which continuously orbit equivalent to acti...
