In this paper we present a method for estimating the available bandwidth of a network path. It is an extension and enhancement of the bandwidth measurement method TOPP. TOPP actively probes a network path by sending probe packets in a predetermined time pattern. Our enhancement involves a formalized estimation algorithm based on constrained linear regression. Using the algorithm, bandwidth meas...

Gamma-ray bursters emit a small fraction of their flux in X rays, and because X-ray detectors are often very sensitive they may probe the gamma-ray burst universe more deeply than the current best gamma-ray instruments. On the reasonable assumptions that spectra of bursts observed by BATSE may be used to predict the X-ray fluxes of gamma-ray bursts, and that any corona of bursts around M31 is s...

Objective: In this paper we report in a larger series the use of radio-probe-guided surgery (RGS) in nonradioiodineavid, well-differentiated thyroid cancer (DTC). Design: Thirty-seven patients with locoregional recurrent, nonradioiodine avid DTC were studied with Tc-sestamibi directed RGS using a handheld gamma probe as an intraoperative detector. Outcome: Twenty-three women and 14 men were fol...

Susceptibility to multiple sclerosis (MS) has been linked to the immunoglobulin G (Gm) markers as well as HLA-DR genes. We have used a genomic Ig gamma 1 probe which detects polymorphisms in the gamma 1, gamma 2, gamma 3 and pseudogamma genes to identify restriction fragment length polymorphisms associated with MS. A negative association was found between a 5.9-kilobase (kb) Bst EII gamma 3 fra...

introduction: radio-guided parathyroid surgery along with other minimally invasive surgeries constitutes the main surgical treatment procedures for different kinds of hyperparathyroidism.  in this article we have reported our experience of radio-guided parathyroid surgery using tc-99m sestamibi. methods: ten patients with hyperparathyroidism included in our study. twenty mci of tc-99m sestamibi...

The redshift where the first stars formed is an important and unknown milestone in cosmological structure formation. The evidence linking gamma ray bursts (GRBs) with star formation activity implies that the first GRBs occurred shortly after the first stars formed. Gamma ray bursts and their afterglows may thus offer a unique probe of this epoch, because they are bright from gamma ray to radio ...

In a new strategy for labeling the active sites of serine proteinases with fluorescence probes (Bock, P. E. (1988) Biochemistry 27, 6633-6639), a thioester peptide chloromethyl ketone inhibitor is incorporated into the enzyme active center and used to produce a unique thiol group which provides a site for selective chemical modification with any one of many thiol-reactive fluorescence probes. T...

Axion-like particles (ALPs) are predicted by many extensions of the Standard Model (SM). When ALP mass lies in range MeV to GeV, cosmology and astrophysics will be largely irrelevant. In this work, we investigate such light ALPs through ALP-strahlung process $pp \to V a (\to \gamma\gamma)$ at 14 TeV LHC with an integrated luminosity 3000 fb$^{-1}$ (HL-LHC). With photon-jet algorithm, demonstrat...

Abstract We investigate the prospect of detecting Dark Matter (DM) candidate in three-loop radiative neutrino mass generation model extended with large electroweak multiplets Standard Model (SM) gauge group, at future imaging atmospheric Cherenkov telescope known as Telescope Array (CTA). find that addition such leads to a sizable Sommerfeld enhanced annihilation DM O (TeV) mass, into SM bosons...
