Meromorphic Functions That Share Fixed-Points
Journal of Mathematical Analysis and Applications, 2002 Let \(f(z)\) and \(g(z)\) be two meromorphic functions, \(n\geq 11\). If \(f^n(z) f'(z)- z\) and \(g^n(z) g'(z)- z\) assume the same zeros with the same multiplicities, then either \[ f(z)= c_1 e^{cz^2},\quad g(z)= c_2 e^{-cz^2}\quad (4(c_1 c_2)^{n+ 1}C^2= -1) \] or \[ f(z)= tg(z)\qquad (t^{n+1}= 1). \] {}.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Direct solution of the inverse optimization problem of load sharing between muscles
, 2006 In the context the statically indeterminate muscular load sharing problem considered in biomechanics of the musculoskeletal system, a method is suggested of constructing an additively separable and homogenous cost function based on a solution to a ...

Meromorphic functions that share four values [PDF]
Transactions of the American Mathematical Society, 1983 An old theorem of R {\text {R}} . Nevanlinna states that if two distinct nonconstant meromorphic functions share four values counting multiplicities, then the functions are Möbius transformations of each other, two of the shared values are Picard values for both functions, and the cross ratio of a particular permutation of ...

Development and simulations of Enhanced Lateral Drift Sensors
, 2019 We present the concept of a new type of silicon tracking sensor called Enhanced Lateral Drift (ELAD) sensor. In ELAD sensors the spatial resolution of the impact position of ionising particles is improved by a dedicated charge sharing mechanism, which is

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
