We undertake a systematic study of sketching quadratic form: given an n x matrix A, create succinct sketch sk(A) which can produce (without further access to A) multiplicative (1+ε)-approximation xT A for any desired query ∈ Rn. While general does not admit non-trivial sketches, positive semi-definite (PSD) matrices sketches size θ(ε{-2 n), via the Johnson-Lindenstrauss lemma, achieving "for each" guarantee, namely, each x, with constant probability succeeds. (For stronger all" where...
This paper presents the design, analysis, and implementation of a novel data center network architecture, named NovaCube. Based on regular Torus topology, NovaCube is constructed by adding number most beneficial jump-over links, which offers many distinct advantages practical benefits. Moreover, in order to enable achieve its maximum theoretical performance, probabilistic oblivious routing algorithm PORA carefully designed. both deadlock livelock free algorithm, achieves near-optimal...
(Cell Reports 32, 108041-1–108041-14.e1–e6; August 11, 2020) In the originally published version of this article, calculation to estimate percentage CCR2+ cell-derived mrPB cells was incorrectly changed by production team. This is corrected as “the estimated proportion CCR2-positive among all 71.20% (57.49% ÷ 0.8074)” and now appears with paper online. The team regrets error. Additionally, bone marrow cell (BMC) number transplanted (by either tBMT, mrBMT, or mrMT) listed authors. number, 1 ×...
The data center network connecting the servers in a plays crucial role orchestrating infrastructure to deliver peak performance users. In order meet high and reliability requirements, is usually constructed of massive number devices links achieve 1:1 oversubscription for workload. However, traffic rarely ever hits capacity practice are underutilized most time, which results an enormous waste energy. Therefore, aiming energy proportional without compromising throughput fault tolerance too...
In this paper, two types of the (2+1)-dimensional breaking soliton equations are investigated, which describe interactions Riemann waves with long waves. With symbolic computation, Hirota bilinear forms and Bäcklund transformations derived for those systems. Furthermore, multisoliton solutions in terms Wronskian determinant constructed, verified through direct substitution into equations. Via technique, it is proved that obtained ones between (N − 1)- N-soliton solutions. Propagations...
We investigate the mixed-type vector solitons of $N$-coupled mixed derivative nonlinear Schr\"odinger ($N$-CMDNLS) equations from optical fibers. Mixed-type ($m$-bright-$n$-antidark or $m$-bright-$n$-dark) vector-soliton solutions are derived via Hirota method. Such found to be independent sign cubic nonlinearity in $N$-CMDNLS equations, which is different case coupled equations. The parameter conditions for shape-preserving and shape-changing collisions also given by an asymptotic analysis....

Binary Bell polynomials are applied to bilinearization system. Bilinear Bäcklund transformation ELV equation constructed. N-soliton solution terms Casorati determinant also presented verified. Propagation interaction behaviors analyzed. It demonstrated that number interacting waves...
Governing the molecular excitations associated with bioenergy transport in an α-helical protein through soliton modes, three-coupled higher-order nonlinear Schrodinger equations variable coefficients are investigated via symbolic computation. Using Bell polynomials, a bilinear form and Backlund transformation derived for this model. Furthermore, explicit N-soliton solutions constructed terms of double Wronskian determinant. Solitonic found to remain stable against disorders parameters under...
With consideration of the molecular structure containing three hydrogen spines and existence protein inhomogeneity, bioenergy transport mechanism in $\alpha$-helical is investigated, which described by three-coupled perturbed nonlinear Schrödinger equations. Via symbolic computation, an infinite number conservation laws multisoliton solutions are derived for underlying soliton dynamics with certain constraints. Through asymptotic analysis, solitonic excitations shown to be influenced thermal...
A recent primitive known as asymmetric group key agreement allows a of users to negotiate common encryption which is accessible any entities while each user holds her respective secret decryption key. This concept not only enables confidential communications among but also permits outsider send encrypted messages the group. The existing instantiation secure against passive adversaries. In this paper, we first propose an authenticated protocol captures practical security properties active...
Thanks to its flexibility and programmable features, Software-Defined Networking (SDN) has been attracting more attention from the academia industry. Unfortunately, fundamental characteristic of SDN that decouples control plane data becomes a potential attack surface as well, which enables adversaries fingerprint SDNs. Existing work showed possibility fingerprinting an with time-based features. However, they are coarse grained. This paper proposes fine-grained approach reveals much severe...
Embedding multiple virtual networks (VNs) onto a shared substrate by allocating resources to nodes and links of VN requests under collection constrains is known be an NP-hard problem even for the offline embedding. To deal with this issue, paper formulates embedding as objective linear programming optimization program, solves it in preemptive strategy decomposing into node mapping link phases. Furthermore, based on AI model, named Blocking Island, we propose efficient online heuristic...
