For each n = 0, 1, 2, . . ., consider the following two rational functions: Rn(t) = (−1)n ( t + n 2 ) n ∏ l=1 (t − l)2 · n ∏ l=1 (t + n+ l)2 n ∏ l=0 (t + l)4 and R̃n(t) = n! n ∏ l=1 (t − l) n ∏ l=0 (t + l)2 n ∑ j=0 ( n j )2 (n+ j n ) n−1 ∏ l=0 (t − j+ l) n! . Problem 1. Prove that the following equality is valid for any n ≥ 0:
H2 pure-rotational emission lines are detected from warm (100–1500 K) molecular gas in 17/55 (31% of) radio galaxies at redshift z < 0.22 observed with the Spitzer IR Spectrograph. The summed H2 0–0 S(0)–S(3) line luminosities are L(H2) = 7 × 1038–2 × 1042 erg s−1, yielding warm H2 masses up to 2 × 1010 M . These radio galaxies, of both FR radio morphological types, help to firmly establish the...
Within the Standard Model, we investigate CP violations and $K_S^0-K_L^0$ asymmetries in $D^{\pm}\rightarrow K^{\ast}(892)^{0} \pi^{\pm} + \bar{K}^{\ast }(892)^{0}\pi^{\pm}\rightarrow K_{S,L}^{0}\pi^0 \pi^{\pm}$ decays basing on factorization-assisted topological-amplitude (FAT) approach topological amplitude (TA) of Cheng Chiang [Phys. Rev. D 104, 073003 (2021).]. We find that these $A_{CP}^{K...

نانوذرات مغناطیسی فریت نیکل- منگنز- مس عمدتأ در دارورسانی مغناطیسی، محیط های مغناطیسی ضبط داده ها، حسگرهای گازی، مدارهای فرکانس بالا و ذخیره اطلاعات و ... کاربرد فراوانی دارند. در این پایان نامه نانوذرات مغناطیسی فریت نیکل - منگنز - مس با درصدهای متفاوت جانشانی مس به جای منگنز به روش هم رسوبی شیمیایی تهیه شدند و خواص ساختاری، مغناطیسی و الکتریکی آنها مورد مطالعه و بررسی قرارگرفت. برای مشخصه یاب...
Rainbow trout, Oncorhynchus mykiss (Walbaum), were exposed continuously to infectious pancreatic necrosis virus (IPNV) at 0, 10(1), 10(3) or 10(5) plaque forming units (pfu) L(-1) of water to estimate the effects of chronic IPNV exposure on early life stages. Fish density averaged 35 fish L(-1) (low density) or 140 fish L(-1) (high density), and the tank flow rate was 250 mL(-1) min. Virus expo...
We report the most precise measurement to date of a parity-violating asymmetry in elastic electron-proton scattering. The measurement was carried out with a beam energy of 3.03 GeV and a scattering angle 〈θlab〉 = 6.0 ◦, with the result APV = (−1.14 ± 0.24 (stat) ± 0.06 (syst)) × 10. From this we extract, at Q = 0.099GeV, the strange form factor combination GsE + 0.080G s M = 0.030 ± 0.025 (stat...
We study the zero-point energy of a massless scalar field subject to spheroidal boundary conditions. Using the zeta-function method, the zero-point energy is evaluated for small ellipticity. Axially symmetric vector fields are also considered. The results are interpreted within the context of QCD flux tubes and the MIT bag model.
Given a smooth projective variety X over a field k of characteristic zero, we consider the composition of the de Rham cohomology cycle class map over k from the Chow group CH q (X × k K), where K is the field of fractions of henselization A h of the local ring of a smooth closed point of a variety over the field k with an appropriate projection:
In this study, we sought to identify the transporters that mediate the uptake of L-carnitine and acetyl-L-carnitine in cultured rat cortical astrocytes. L-[(3)H]carnitine and acetyl-L-[(3)H]carnitine uptake were both saturable, and mediated by a single Na(+)-dependent transport system. Uptake of both was inhibited by L-carnitine, D-carnitine, acetyl-L-carnitine and various organic cations. Acyl...
