Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

A Boy and a Box: Secret Fort

open access: yes, 2020
Secret Fort Stoneware with Glaze 8.5” x 4” x 4” 2020 The first thing Redd makes from this cardboard box is a fort. He uses a blanket and a ball, which he collected previously, shown in the last piece.

DPA Attacks and S-Boxes [PDF]

open access: yes, 2005
For the power consumption model called Hamming weight model, we rewrite DPA attacks in terms of correlation coefficients between two Boolean functions. We exhibit properties of S-boxes (also called (n,m)-functions) relied on DPA attacks. We show that these properties are opposite to the non-linearity criterion and to the propagation criterion.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Smashing the Implementation Records of AES S-box

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2018
Canright S-box has been known as the most compact S-box design since its introduction back in CHES’05. Boyar-Peralta proposed logic-minimization heuristics that could reduce the gate count of Canright S-box from 120 gates to 113 gates, however synthesis ...

A Boy and a Box: Resting

open access: yes, 2020
Resting Stoneware with Glaze 6.5” x 5.5” x 3” 2020 In this final piece of this series, after a long journey of creating, Redd rests. He does so by using the box in its simplest form.

A review of cryptographic properties of S-boxes with generation and analysis of crypto secure S-boxes. [PDF]

open access: yes, 2018
In modern as well as ancient ciphers of public key cryptography, substitution boxes find a permanent seat. Generation and cryptanalysis of 4-bit as well as 8-bit crypto S-boxes is of utmost importance in modern cryptography. In this paper, a detailed review of cryptographic properties of S-boxes has been illustrated.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

S-Boxهای پویای وابسته به کلید سبک وزن مبتنی بر ابرخم بیضوی برای دستگاه¬های اینترنت اشیا

open access: yesعلوم رایانش و فناوری اطلاعات, 2021
Security is one of the main issues in Internet of Things (IoT). Encryption plays a curtail role in making these systems secure. Substitution Box (S-Box) has an effective impact in block encryption methods. Due to the restricted resource capacities of IoT
