Soil structure after treatment with different operation modes of spading machine [PDF]
Agricultural Science and Technology, 2018 . The article presents the results of a field survey of the work of a spading machine. The influence of the following factors has been investigated: operating speed, deflector cover deflection angle and rotation speed of the power take-off shaft of the ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Operation modes and workspace of a 4-rRUU Parallel Manipulator
, 2019 International audienceA lower-mobility parallel manipulator with multiple operation modes can be considered as inherently reconfigurable. This is the case for 4-RUU parallel manipulators that have three different operation modes.

Механика машин, механизмов и материалов, 2019 A mathematical model of the load of the shearer drive of the drum type cutting unit is introduced. It takes into account the speed of its movement, the angular speed of rotation of the cutting unit, the taper angle of the cutting part and the number of ...

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Cryptanalysis of the EMD Mode of Operation [PDF]
, 2003 In this paper, we study the security of the Encrypt-Mask-Decrypt mode of operation, also called EMD, which was recently proposed for applications such as disk-sector encryption. The EMD mode transforms an ordinary block cipher operating on n-bit blocks into a tweakable block cipher operating on large blocks of size nm bits.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Cryptanalysis of Triple-Modes of Operation
, 1996 Multiple modes of operation, and in particular, triple-modes of operation were suggested as a simple method to improve the strength of blockciphers, and in particular of DES.

Quantum-Resistant Authenticated Encryption Variants of GCM
IACR Transactions on Symmetric CryptologyCommon authenticated encryption schemes are generally believed to remain secure in the post-quantum setting where adversaries with local quantum power interact classically with the users.
