An explicit solution for calculating optimum spawning stock size from Ricker’s stock recruitment model [PDF]
PeerJ, 2016 Stock-recruitment models have been used for decades in fisheries management as a means of formalizing the expected number of offspring that recruit to a fishery based on the number of parents.

Fixed points of composite entire and quasiregular maps [PDF]
, 2005 We give a new proof of the result that if f and g are transcendental entire functions, then the composite function f(g) has infinitely many fixed points. The method yields a number of generalization of this result.

Macromolecular Rapid Communications, EarlyView.Polypeptide chains were extended from both ends of aromatic diamines by chemoenzymatic polymerization, resulting in the synthesis of telechelic polyglycines (TPG) and polyalanines (TPA). These telechelic polymers assembled into branched nanofibrils through π‐π stacking of aromatic rings, with the polymer backbones bent at the aromatic unit.

Polymer Engineering &Science, EarlyView.Generalized analytical equations were developed that accurately predict the local pumping characteristics, viscous dissipation, and average shear rates in channels of both conventional and high‐performance single‐screw extruders. Applied within segmented extruder calculations, these models aid in screw design and process troubleshooting without the ...

Sustainability as Justice: Making the “Leave No One Behind” Work
Sustainable Development, EarlyView.ABSTRACT This paper critically engages with the LNOB principle of the 2030 Agenda, highlighting its conceptual, methodological, and structural limitations. Building on Amartya Sen's social choice theory and Rawlsian justice, it reconceptualizes “sustainability as justice,” emphasizing real‐world comparative assessments grounded in intersectionality. It

Alexandria Engineering JournalWith a generalized setting of transcendental functions associated with a non-linear variable, we have observed the combinatorial structures of the fractals of Julia sets and Mandelbrot sets due to the function zκcos(zκ)+pz2+q, in the complex plane with p,

Hopf Algebras and Transcendental Numbers [PDF]
, 2008 In dealing with multiple zeta values, the main diophantine challenge is to prove that known dependence relations among them suffice to deduce all algebraic relations. One tool which should be relevant is the structure of Hopf Algebras, which occurs in several disguises in this context.

Economic Anthropology, EarlyView.ABSTRACT The khipu knotted string records in the ancient Andes were accounting systems, but they did not indicate any concepts of commensurability or exchange value. They were not incipient money; instead, monetized commerce appears to have predated the economic organization of the Inca society. The article begins by tracing the emergence of coinage in

A Novel Method for Image Encryption Based on Chaos and Transcendental Numbers
IEEE Access, 2019 In this paper, a method for image encryption is proposed based on a novel approach using chaos and transcendental numbers for generating the substitution box and the ciphering keys. The Chaotic Pi Ciphering (CPC) is a robust symmetric cryptosystem of the
