BACKGROUND Vascular endothelial cells (ECs) express and release protein components of the complement pathways, as well as secreting and anchoring ultra-large von Willebrand factor (ULVWF) multimers in long string-like structures that initiate platelet adhesion during hemostasis and thrombosis. The alternative complement pathway (AP) is an important non-antibody-requiring host defense system. Th...

Space-economical estimation of the pth frequency moments, defined asFp = Pn i=1|fi| , for p > 0, are of interest in estimating all-pairs distances in a large data matrix [14], machine learning, and in data stream computation. Random sketches formed by the inner product of the frequency vector f1, . . . , fn with a suitably chosen random vector were pioneered by Alon, Matias and Szegedy [1], and...

Keterampilan berpikir kritis diperlukan dalam kegiatan pembelajaran matematika diera abad 21. Profil keterampilan siswa bergantung pada gaya kognitif yang terdiri dari Field Dependent (FD) dan Independent (FI). Selain itu perbedaan gender juga memberikan ragam profil siswa. Tujuan penelitian ini untuk mendeskripsikan ditinjau gender. Penelitian deskriptif kualitatif dengan desain studi kasus di...

For a nonempty graph G = (V, E), a signed edge-domination of G is a function f : E(G) → {1,−1} such that ∑e′∈NG [e] f (e′) ≥ 1 for each e ∈ E(G). The signed edge-domatic number of G is the largest integer d for which there is a set { f1, f2, . . . , fd} of signed edge-dominations of G such that ∑d i=1 fi (e) ≤ 1 for every e ∈ E(G). This paper gives an original study on this concept and determin...

We study Standard Model four-fermion production in e+e− annihilation at LEP2 energies and above using a semi-analytical approach. We derive the complete QED initial state corrections (ISR) to the reactions e+e− → (Z0Z0) → f1f̄1f2f̄2 and e+e− → (W+W−) → f̄u 1 fd 1 fu 2 f̄d 2 with f1 6= f2 and fi 6= e±, (−) νe . As compared to the well-known universal s-channel ISR, additional complexity arises due t...

Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif karena tujuan adalah mendeskripsikan profil kemampuan literasi matematika siswa berdasarkan gaya kognitif dan gender Subjek yaitu satu FI laki-laki, perempuan, FD perempuan. Instumen berupa tes indikator PISA, serta pedoman wawancara. Indikator enam level siswa. Berdasarkan analisis data hasil transkrip wawancara dipero...

ρf,` : Gal(k̄/k)→ Aut(Jf [`](k̄)) ' GL2g(F`) on the `-torsion points of Jf is as big as possible for almost all primes `, if the following two (sufficient) conditions hold: (1) the endomorphism ring of Jf is Z; (2) for some prime ideal p ⊂ Zk, the fiber over p of the Néron model of Cf is a smooth curve except for a single ordinary double point. These conditions can be translated concretely in ter...
