One aspect of Mobile Wireless Sensor Networks (MWSNs) is the MAC protocol, which is critical in terms of reliability, delay and energy consumption. This work begins with a literature review, showing that the majority of MWSN MACs are designed for hierarchical architectures, demonstrating that there is a lack of MACs intended for flat architecture MWSNs. Subsequently, we propose three new MAC pr...

Genetic and biochemical sperm integrity is essential to ensure the reproductive competence. However, spermatogenesis involves physiological changes that could endanger sperm integrity. DNA protamination and apoptosis have been studied extensively. Furthermore, elevated rates of aneuploidy and DNA injury correlate with reproductive failures. Consequently, this study applied the conventional sper...

Message authentication codes (MACs) are an essential primitive in cryptography. They are used to ensure the integrity and authenticity of a message, and can also be used as a building block for larger schemes, such as chosenciphertext secure encryption, or identity-based encryption. MACs are often built in two steps: first, the ‘front end’ of the MAC produces a short digest of the long message,...

We consider zero-error communication over a two-transmitter deterministic adversarial multiple access channel (MAC) governed by an adversary who has to the transmissions of both senders (hence called omniscient ) and aims maliciously corrupt communication. None encoders, jammer decoder is allow...

The control of chemical, morphological, textural and magnetic properties developed in activated carbons (MACs) from industrial food waste, was achieved. process parameters involved a sustainable optimized one-step activation route, based on the circular economy model, played an important role its influence studied, offering interesting outstanding results. Magnetite crystals were formed MACs su...

Objective. To examine whether density gradient centrifugation (DGC) alone or its combination with annexin V magnetic-activated cell sorting (DGC-MACS) can be used to process semen samples from infertile male patients poor sperm quality prior subjecting these freeze/thaw in order optimize the outcomes of freezing. Methods. This study enrolled sixteen <math xmlns="http://www.w3.org/1998/Math/Math...

SipHash is a family of pseudorandom functions optimized for short inputs. Target applications include network traffic authentication and hash-table lookups protected against hash-flooding denial-of-service attacks. SipHash is simpler than MACs based on universal hashing, and faster on short inputs. Compared to dedicated designs for hash-table lookup, SipHash has well-defined security goals and ...
