Plant identification is very important in control design. The relay method belongs among special kinds of experimental frequency response identification. It was originally used for plant identification by Rotach (Rotač, 1964) and lately also for controller autotuning, see reference (Åstrőm & Wittenmark, 1989; Åstrőm, 1993; Åstrőm & Hägglund, 1995; Bi et al., 1997; Hang et al., 1993; Lu et al., ...

BACKGROUND AND AIMS In the last decade, genomic studies using DNA markers have strongly influenced the current phylogeny of angiosperms. Genome size and ploidy level have contributed to this discussion, being considered important characters in biosystematics, ecology and population biology. Despite the recent increase in studies related to genome size evolution and polyploidy incidence, only a ...

Miranda-Filho et al. in their recently published paper entitled “Cancers of the brain and CNS: global patterns and trends in incidence” provided a global status report of the geographic and temporal variations in the incidence of brain and CNS cancers in different countries across continents worldwide. While the authors confirm the role of genetic risk factors and ionizing radiation exposur...

Pleotrophin (PTN), a secretory growth factor, is also known as heparin affinity regulatory peptide (Laaroubi et al., 1995), heparin binding growth associated molecule (Hampton et al., 1992), heparin binding growth factor-8 (Milner et al., 1989), and heprin binding neutrophic factor (Kovesdi et al., 1990), due to its high affinity to heparin. PTN shares 50% homogeneous amino acid sequenc with mi...

Correction for ‘Formamidinium-based Ruddlesden–Popper perovskite films fabricated via two-step sequential deposition: quantum well formation, physical properties and film-based solar cells’ by Jing Lu et al. , Energy Environ. Sci. 2022, 15 1144–1155, DOI: 10.1039/D1EE02851K.

Epithelial morphogenesis is a fundamental and widespread process controlling cell, tissue and organ development, hence the ultimate shape and organization of metazoans. The ability of fields of cells to translate spatial and temporal information into appropriate morphogenetic activity is crucial for the making of a functional organism. In Drosophila, several genes have been identified that are ...

Recently, the security of RSA variants with moduli N = pq, e.g., the Takagi RSA and the prime power RSA, have been actively studied in several papers. Due to the unusual composite moduli and rather complex key generations, the analyses are more involved than the standard RSA. Furthermore, the method used in some of these works are specialized to the form of composite integers N = pq. In this pa...

INTRODUCTION Hepatic steatosis, the accumulation of lipid within hepatocytes, is a critical step in the pathogenesis of human diseases such as alcoholic liver disease, non-alcoholic fatty liver disease associated with the metabolic syndrome, chronic hepatitis C infection and other disorders. In more severe forms of these conditions, the liver becomes inflamed and fatty liver progresses to non-a...

Dear editor Regarding the duration of supplement therapy in our study which has been published in the Avicenna J Phytomed, 2019; 9(1): 1-9, “The effects of curcumin on the prevention of atrial and ventricular arrhythmias and heart failure in patients with unstable angina” (Dastani et al., 2019),  some critical flaws has been mentioned. Primarily, we are grateful for the consi...
