Let M1 and M2 be compact, orientable 3-manifolds, and M the manifold obtained by gluing some component F of ∂M1 to some component of ∂M2 by a homeomorphism φ. We show that when φ is “sufficiently complicated” then (1) the amalgamation of low genus, unstabilized, boundary-unstabilized Heegaard splittings of Mi is an unstabilized splitting of M , (2) every low genus, unstabilized Heegaard splitti...

PURPOSE To investigate the changes in the epithelium and flap after laser in situ keratomileusis (LASIK), when measured with optical coherence tomography (OCT). METHODS Twenty-eight eyes of 14 patients (age: 39.9 +/- 8.6 years) underwent LASIK. The central thickness of corneal epithelium and flap were measured with a real-time 1310 nm OCT 1 day, 1 week, and 1 month after surgery. A custom sof...

Different species of Triticum were grown during a greenhouse experiment, including T. monococcum L., T. dicoccum Schrank, T. durum Desf., T. spelta L. and T. aestivum cv. Vánek. The goal was to establish the influence of irradiance on the parameters of photosynthetic performance in relation to their ploidy. Photosynthetic rate (Pn), transpiration (E) and stomatal conductance (gs) were measured ...

Abstract Aquatic plants of Hydrilla verticillata have a role as provider natural food for the aquatic biota Laut Tawar Lake. This study aimed to analyze biomass growth submerged plant found in KJA and non-KJA areas lake. The research was conducted from January April 2022 Lake, Central Aceh Regency. method used determining station this is purposive sampling. Data collection on carried out at 2 o...

lmidazolate bridged homo/hetero binuclear complexes of copper(II), nickei(II) and zinc(II) formed with glycylvalinate have been studied by pH-metry, EPR and visible absorption spectrometry in aqueous medium at 25 ± I 0 and I= 0.1 M NaCI04• The experimental data have been obtained for the followin~ species (A. = glycylvalinate and 8 =imidazole) :M +, AHt , AH, A·, 8W, 8 , M(OHt.

The endocannabinoid 2-arachidonoylglycerol (2-AG) has been shown to activate human platelets in platelet-rich plasma, by binding to a "platelet-type" cannabinoid receptor (CB(PT)). Here, washed human platelets were used to characterize the binding of [(3)H]2-AG to CB(PT), showing a dissociation constant (Kd) of 140 +/- 31 nM and a maximum binding (Bmax) of 122 +/- 10 pmol.mg protein(-1). Select...

STEP 0: Suppose that for some ε > 0, the statement is not true. Then one can find an increasing sequence m1, m2, etc., such that for any j, in equilibrium (S∗ mj Y ∗ mj ), E[|yKmj − X(ω)|] ≥ ε. Consider this sequence for the rest of the proof. For notational convenience, without loss of generality, we assume that m1 = 1, m2 = 2, etc.; that is, we have a sequence of games ΓKm and corresponding e...

Proof. First note that the map φ is uniquely determined by its components φ11, φ12, φ21, φ22. Indeed, by the universal property of the coproduct M1 ⊕ M2 we see that φ is uniquely determined by the maps φ∗1 := φ◦ι1 and φ∗2 := φ◦ι2. Then from the universal property of the product N1⊕N2 we see that the map φ∗1 is uniquely determined by the maps φ11 = π1 ◦φ∗1 and φ21 = π2 ◦ φ∗1. Similarly, φ∗2 is u...

We present a brief review of the status and phenomenology of B Xs decays. The B Xs rate is known at the next-to-next-to-leading order in QCD and NLO in QED. QED corrections include only log-enhanced corrections of the type αem ln M2 W mb and αem ln m 2 b m 2 . The latter originate from a collinear singularity, they vanish when integrated over the whole phase space but survive the integration ov...
