Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS 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)

Comparative Study of XML Parsing Methods in Heterogeneous Text Data Conversion [PDF]

open access: yesJisuanji gongcheng, 2020
This paper compares and studies the DOM,SAX,JDOM,DOM4J methods for parsing XML texts in heterogeneous text data conversion.The pros and cons of the four parsing methods are judged based on parsing time,memory heap space,and CPU occupancy rate.The ...

Space Efficient $GF(2^m)$ Multiplier for Special Pentanomials Based on $n$ -Term Karatsuba Algorithm

open access: yesIEEE Access, 2020
Recently, new multiplication schemes over the binary extension field GF(2m) based on an n-term Karatsuba algorithm have been proposed for irreducible trinomials. In this paper, we extend these schemes for trinomials to any irreducible polynomials.

Algebraic Distributed Space-Time Codes with Low ML Decoding Complexity

open access: yes, 2007
"Extended Clifford algebras" are introduced as a means to obtain low ML decoding complexity space-time block codes. Using left regular matrix representations of two specific classes of extended Clifford algebras, two systematic algebraic constructions of

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Predictability problems of global change as seen through natural systems complexity description. 2. Approach

open access: yesDiscrete Dynamics in Nature and Society, 1998
Developing the general statements of the proposed global change theory, outlined in Part 1 of the publication, Kolmogorov's probability space is used to study properties of information measures (unconditional, joint and conditional entropies, information

Distances in Probability Space and the Statistical Complexity Setup

open access: yesEntropy, 2011
Statistical complexity measures (SCM) are the composition of two ingredients: (i) entropies and (ii) distances in probability-space. In consequence, SCMs provide a simultaneous quantification of the randomness and the correlational structures present in ...

Scale, context, and heterogeneity: the complexity of the social space

open access: yesScientific Reports, 2022
The social space refers to physical or virtual places where people interact with one another. It decisively influences the emergence of human behaviors. However, little is known about the nature and complexity of the social space, nor its relationship to

On the probabilistic continuous complexity conjecture [PDF]

open access: yes, 2012
In this paper we prove the probabilistic continuous complexity conjecture. In continuous complexity theory, this states that the complexity of solving a continuous problem with probability approaching 1 converges (in this limit) to the complexity of ...

Completeness Results for Parameterized Space Classes

open access: yes, 2013
The parameterized complexity of a problem is considered "settled" once it has been shown to lie in FPT or to be complete for a class in the W-hierarchy or a similar parameterized hierarchy.
