New Masjed Jamei–Type Inequalities for Inverse Trigonometric and Inverse Hyperbolic Functions
Mathematics, 2022 In this paper, we establish two new inequalities of the Masjed Jamei type for inverse trigonometric and inverse hyperbolic functions and apply them to obtain some refinement and extension of Mitrinović–Adamović and Lazarević inequalities.

Sharp bounds for Seiffert means in terms of Lehmer means [PDF]
Journal of Mathematical Inequalities, 2010 In this paper, we establish two sharp inequalities as follows: P(a,b) > L− 6 (a,b) and T (a,b) 0 with a = b . Here, Lr(a,b) , P(a,b) and T (a,b) are the Lehmer, first and second Seiffert means of a and b , respectively. Mathematics subject classification (2010): 26E60.

On the Brink, a Population of Hedgehogs in Central London. [PDF]
Ecol EvolA small breeding population of hedgehogs survives in central London's Regent's Park (166 ha). A 10‐year survey (2014–2023) revealed a decline from an average of 28 individuals to just six in spring 2023, driven by low breeding success and high mortality.

Abstract and Applied Analysis, 2013 Optimal bounds for the weighted geometric mean of the first Seiffert and logarithmic means by weighted generalized Heronian mean are proved. We answer the question: for what the greatest value and the least value such that the double inequality ...

Journal of Inequalities and Applications, 2017 In the article, we prove that the double inequality α L ( a , b ) + ( 1 − α ) T ( a , b ) < NS ( a , b ) < β L ( a , b ) + ( 1 − β ) T ( a , b ) $$ \alpha L(a,b)+(1-\alpha)T(a,b)< \mathit{NS}(a,b)< \beta L(a,b)+(1-\beta)T(a,b) $$ holds for a , b > 0 $a,b>

The Deep Diffuse Extragalactic Radio Sky at 1.75 GHz [PDF]
, 2014 We present a study of diffuse extragalactic radio emission at $1.75\,$GHz from part of the ELAIS-S1 field using the Australia Telescope Compact Array. The resulting mosaic is $2.46\,$deg$^2$, with a roughly constant noise region of $0.61\,$deg$^2$ used ...

The Planck-LFI instrument: analysis of the 1/f noise and implications for the scanning strategy [PDF]
, 1999 We study the impact of the 1/f noise on the PLANCK Low Frequency Instrument (LFI) osbervations (Mandolesi et al 1998) and describe a simple method for removing striping effects from the maps for a number of different scanning stategies.

Optimal Lower Generalized Logarithmic Mean Bound for the Seiffert Mean
Journal of Applied Mathematics, 2013 We present the greatest value p such that the inequality P(a,b)>Lp(a,b) holds for all a,b>0 with a≠b, where P(a,b) and Lp(a,b) denote the Seiffert and pth generalized logarithmic means of a and b, respectively.

ARCADE 2 Measurement of the Extra-Galactic Sky Temperature at 3-90 GHz [PDF]
, 2009 The ARCADE 2 instrument has measured the absolute temperature of the sky at frequencies 3, 8, 10, 30, and 90 GHz, using an open-aperture cryogenic instrument observing at balloon altitudes with no emissive windows between the beam-forming optics and the ...

Improvements of bounds for the Sándor–Yang means
Journal of Inequalities and Applications, 2019 In the article, we provide new bounds for two Sándor–Yang means in terms of the arithmetic and contraharmonic means. Our results are the improvements of the previously known results.
