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...

Expression of phosphotidylserine by fetal oocytes in culture renders significant numbers of such cells able to bind AnnexinV-coated microbeads and allows their separation from Annexin V-negative oocytes on a Magnetic Cell Separation (MACS) column in a magnetic field. The majority of oocytes (> or =75%) which bound Annexin V-coated microbeads were viable, as indicated by their propidium iodine (...

Currently, cell separation occurs almost exclusively by density gradient methods and by fluorescence- and magnetic-activated cell sorting (FACS/MACS). These variously suffer from lack of specificity, high cell loss, use of labels, and high capital/operating cost. We present a dielectrophoresis (DEP)-based cell-separation method, using 3D electrodes on a low-cost disposable chip; one cell type i...

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 ...

Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...
