Based on the recurrence relations on the coefficients of the Boros-Moll polynomials Pm(a) = ∑ i di(m)a i derived independently by Kauers and Paule, and Moll, we are led to the discovery of the reverse ultra log-concavity of the sequence {di(m)}. We also show that the sequence {i!di(m)} is log-concave for m ≥ 1. Two conjectures are proposed.

Miconazole is reduced at mercury electrode above pH 6 involving organometallic compound formation, responsible for an anomalous polarographic behavior. The electrodic process presents a large contribution of the adsorption effects. The drug can be determined by cathodic stripping voltammetry from 8.0 x 10(-8) to 1, 5 x 10(-6) molL-1 in Britton-Robinson buffer pH 8.0, when pre-accumulated for 30...

In their study of a quartic integral, Boros and Moll discovered a special class of Jacobi polynomials, which we call the Boros-Moll polynomials. Kauers and Paule proved the conjecture of Moll that these polynomials are logconcave. In this paper, we show that the Boros-Moll polynomials possess the ratio monotone property which implies the log-concavity and the spiral property. We conclude with a...

The amiloride-sensitive Na + /H + antiporter in defolliculated oocytes of Xenopus laevis was characterized by measurements of H Na + influx and apparent H + efflux. Uptake of ^Na"" was linear over a 90-min incubation period and was inhibited approximately 80% with 5xlO~moll~ amiloride. Amiloride-sensitive sodium uptake was reduced following collagenase treatment or oocyte aging. Ko 5 for amilor...

Moll (S Afr J Sci. 2023;119(1/2), Art. #12916) argues that we are not currently living in the Fourth Industrial Age (4IR). In this response to Moll, I contest Moll’s argument does correctly reflect understanding or definition of 4IR as presented pivotal texts leading global and South African advocates. believe that, had focused on initially by Schwab, is, around fusion technologies across digit...

Primary signet-ring cell/histiocytoid carcinomas of the eyelid are extremely rare tumors considered to originate from sweat glands. Here, we report the case of a 72-year-old man diagnosed with primary signet-ring cell/histiocytoid carcinoma of the eyelid and present immunohistochemical analyses of the eyelid apocrine gland (Moll gland) and apocrine and eccrine sweat glands of perineum and axill...

In this paper, we investigate the 2-adic valuation of the Stirling numbers S(n, k) of the second kind. We show that v2(S(2n + 1, k + 1)) = s2(n) − 1 for any positive integer n, where s2(n) is the sum of binary digits of n. This confirms a conjecture of Amdeberhan, Manna and Moll. We show also that v2(S(4i, 5)) = v2(S(4i + 3, 5)) if and only if i 6≡ 7 (mod 32). This proves another conjecture of ...

1. Uptake studies using radioactive octopamine have revealed that the larval lantern of the Photuris firefly possesses a concentrative, high-affinity uptake system for octopamine. This compound has been shown previously to be the neurotransmitter of the photomotor neurones. 2. Imipramine is a potent inhibitor of the uptake of octopamine in the lantern. At 10~moll~', it reduces specific uptake o...
