Proportional Topology Optimization: A new non-gradient method for solving stress constrained and minimum compliance problems and its implementation in MATLAB [PDF]

open access: yes, 2014
A new topology optimization method called the Proportional Topology Optimization (PTO) is presented. As a non-gradient method, PTO is simple to understand, easy to implement, and is also efficient and accurate at the same time. It is implemented into two

Influence of errors in job codes on job exposure matrix-based exposure assessment in the register-based occupational cohort DOC*X

open access: yesScandinavian Journal of Work, Environment & Health, 2020
OBJECTIVE: Job-exposure matrices (JEM) may be efficient for exposure assessment in occupational epidemiological studies, but they rely on valid job information.

Dihedral Group in The Ancient Genetic

open access: yesJurnal Matematika Integratif, 2020
The standard genetic code consist of four nucleotide bases which encode genes to produce amino acids needed by living things. The addition of new base  (Dummy) causes a sequence of bases to become five nucleotide bases called ancient genetic codes.

Plasminogen activator inhibitor type 2 contains mRNA instability elements within exon 4 of the coding region. Sequence homology to coding region instability determinants in other mRNAs.

open access: yesThe Journal of biological chemistry, 2001
Plasminogen activator inhibitor type 2 (PAI-2) is a serine protease inhibitor that inhibits urokinase. Constitutive and regulated PAI-2 gene expression involves post-transcriptional events, and an AU-rich mRNA instability motif within the 3'-untranslated region of PAI-2 mRNA is required for this process (Maurer, F., Tierney, M., and Medcalf, R.

A photon loss tolerant Zeno CSIGN gate [PDF]

open access: yes, 2006
We model an optical implementation of a CSIGN gate that makes use of the Quantum Zeno effect [1,2] in the presence of photon loss. The raw operation of the gate is severely affected by this type of loss.

Rateless Coding Schemes Using Polar Codes: Truly “No” Rates?

open access: yesIEEE Access, 2020
In this paper, aiming to achieve rate adaptation for the rateless coding (RC) schemes of polar codes, we explore their throughput efficiency and optimize a series of rates that are set in two types of RC schemes.

Introducing a new tool to navigate, understand and use International Codes of Nomenclature [PDF]

open access: yesPeerJ, 2019
Background In order to designate the various concepts of taxa in biology, evolution and paleontology, scientists have developed various rules on how to create unique names for taxa. Different Codes of Nomenclature have been developed for animals, plants,

Anthropological Discourse in the Performative Context of Body-Spatial Experience [PDF]

open access: yesFuture Human Image, 2020
The article deals with the discovery of a performative context of anthropological discourse. This requires a revision of customary discursive codes “nature/culture” and “culture/civilization” as they are built on the false dualism of the spiritual and ...

Comparison of Polar Decoders with Existing Low-Density Parity-Check and Turbo Decoders

open access: yes, 2017
Polar codes are a recently proposed family of provably capacity-achieving error-correction codes that received a lot of attention. While their theoretical properties render them interesting, their practicality compared to other types of codes has not ...
