Effective engineering of the Internet is predicated upon a detailed understanding issues such as large-scale structure its underlying physical topology, manner in which it evolves over time, and way constituent components contribute to overall function. Unfortunately, developing deep these has proven be challenging task, since turn involves solving difficult problems mapping actual characterizing it, models that capture emergent behavior. Consequently, even though there are number topology...
Very few techniques have been proposed for estimating traffic matrices in the context of Internet traffic. Our work on POP-to-POP (TM) makes two contributions. The primary contribution is outcome a detailed comparative evaluation three existing techniques. We evaluate these methods with respect to estimation errors yielded, sensitivity prior information required and statistical assumptions they make. study impact characteristics such as path length amount link sharing errors. Using actual...
Recent empirical studies [6] have shown that Internet topologies exhibit power laws of the form y = x α for following relationships: (P1) outdegree node (domain or router) versus rank; (P2) number nodes outdegree; (P3) pairs within a neighborhood size (in hops); and (P4) eigenvalues adjacency matrix rank. However, causes appearance such not been convincingly given. In this paper, we examine four factors in formation topologies. These are (F1) preferential connectivity new to existing nodes;...
Abstract The existence of nonzero neutrino masses points to the likely multiple Standard Model neutral fermions. When such states are heavy enough that they cannot be produced in oscillations, referred as leptons (HNLs). In this white paper, we discuss present experimental status HNLs including colliders, beta decay, accelerators, well astrophysical and cosmological impacts. We importance continuing search for HNLs, its potential impact on our understanding key fundamental questions,...
Abstract Neutrinos are one of the most promising messengers for signals new physics Beyond Standard Model (BSM). On theoretical side, their elusive nature, combined with unknown mass mechanism, seems to indicate that neutrino sector is indeed opening a window physics. experimental several long-standing anomalies have been reported in past decades, providing strong motivation thoroughly test standard three-neutrino oscillation paradigm. In this Snowmass21 white paper, we explore potential...
In this paper we explore the evolution of both Internet's most heavily used transport protocol, TCP, and current network environment with respect to how network's ultimately impacts end-to-end protocols. The traditional assumptions about Internet are increasingly challenged by introduction intermediary elements (middleboxes) that intentionally or unintentionally prevent alter behavior communications. This provides measurement results showing impact on a number proposed protocol mechanisms...
A search for the relic neutrinos from all past core-collapse supernovae was conducted using 1496 days of data Super-Kamiokande detector. This analysis looked electron-type antineutrinos that had produced a positron with an energy greater than 18 MeV. In absence signal, 90% C.L. upper limits on total flux were set several theoretical models; these ranged 20 to 130 macro nu(e) cm(-2) s(-1). Additionally, bound 1.2 s(-1) supernova neutrino in region E(nu)>19.3

Two different nuclear-medium effects are isolated using a low three-momentum transfer subsample of neutrino-carbon scattering data from the MINERvA neutrino experiment. The observed hadronic energy in charged-current $\nu_\mu$ interactions is combined with muon kinematics to permit separation quasielastic and $\Delta$(1232) resonance processes. First, we observe small cross section at very that matches expected screening effect long-range nucleon correlations. Second, additions event rate...
