Constituting the polity, constituting the demos: on the place of the all affected interests principle in democratic theory and in resolving the democratic boundary problem

open access: yesEthics & Global Politics, 2012
This essay considers the role of the ‘all affected interests’ principle in democratic theory, focusing on debates concerning its form, substance and relationship to the resolution of the democratic boundary problem.

On the solvability of a semi-periodic boundary value problem for the nonlinear Goursat equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper, by means of a change of variables, a nonlinear semi-periodic boundary value problem for the Goursat equation is reduced to a linear gravity problem for hyperbolic equations. Reintroducing a new function, the obtained problem is reduced to

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Second-Order Boundary Value Problem with Integral Boundary Conditions

open access: yesBoundary Value Problems, 2011
The nonlinear alternative of the Leray Schauder type and the Banach contraction principle are used to investigate the existence of solutions for second-order differential equations with integral boundary conditions.

A Boundary Class for the k-Path Partition Problem [PDF]

open access: yes, 2018
We establish the first known boundary class for the k-path partition problem and deduce that for a graph class defined by finitely many minimal forbidden induced subgraphs, the k-path partition problem remains NP-hard unless one of the forbidden induced ...

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

open access: yesFEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

open access: yesFEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
