Resistive random access memory (ReRAM) holds promise for building computing-in-memory (CIM) architectures to execute machine learning (ML) applications. However, existing ReRAM technology faces challenges such as cell and cycle variability, read-disturb and limited endurance, necessitating improvements in devices, algorithms and applications. Understanding the behaviour of ReRAM technologies is crucial for advancement.

This research aims to explore the association between childhood cancer in children under 6 years old and COVID-19 immunisation, in addition to the effects of vaccination on parents before delivery.
Method: The study employs a case-control approach, gathering informed consent and matching factors like age, marital status, and socioeconomic status between cases and controls.
In this study, the Israeli acute paralysis virus (IAPV), a single-stranded RNA virus, was investigated in honey bee colonies, which had a history of mortality, population decline, and parasitic diseases. Samples (adult honey bees) were collected from 328 apiaries from three provinces (Tehran, Alborz, and Mazandaran) of Iran to detect IAPV. After sample preparation, RNA was extracted and cDNA was synthesized to perform the reverse transcription polymerase chain reaction (RT-PCR) method using a PCR primer pair, and a 185 bp fragment was amplified.

It is the rarest type of twin pregnancy and usually has significant developmental or congenital abnormalities, a higher rate of abortion, perinatal morbidity, and mortality. There is no information regarding monoamniotic twins in livestock species.

The objective of this study was to generate transgenic puppies from a founder dog expressing the mutated human amyloid precursor protein (mhAPP) gene. Experiment I assessed the characteristics of the semen prepared by freshly diluted, swim-up, and Percoll gradient methods using a computer-assisted semen analyzer (CASA).
