Transcriptome refers to all RNA particles occur inside one cell or inside numerous cells in One organ. Coronaviruses are a family of correlated viruses that induce iral infection. In humans. coronaviruses induce respiratory viral infections that may be mild or dangerous. The coronas irus shape is large circular elements that has e round tip outbreaks - the virus diameter particles=120 nm. The RNA viral genome occurs in coronavirus. The coronas irus genome size = 27-34 kilobases and this size is the largest RNA genome size, The Life cycle of coronavirus includes v iral entry replication and release. Coronas irus transmission was done through the connection of its protein with host cell receptors in a specific process. There are 4 types of coronas irus genus: (1) A 1phacoronavirus. (2) I3c facoronavir2r (3) Gammocoronovnws, and (4) ncttacwonavirus. Viral replication,, immune evasion and virion biogenesis correlated with host cell transformation mechanism. Viral molecular mechanism hijacks the host cell protein production mechanism. There is an important host factor (CPSF6) that connects with nuclear protein (NP 1). The CPSF6 increases the nuclear production of N P1 in the same time. CPSF6 possesses an important role in the progress of capsid mRNAs inside the nucleus. In a viral infection there is an increase in mRNA. myeloid differentiation 2 -related lipid recognition protein (ML). and Niemann Pick -type Cl (N PC) genes, Coronavirus is capable of replicating in in vin-o study and causes lower transcriptomic variations before 12 h after viral infection. As infection progress. coronas irus causes a significant dysregulation of the host transcriptome greater than the SARS virus. In conclusion. future transcriptome studies are the basis for detecting coronavirus in the human host and for developing a specific pro entis e and therapeutic method for the virus.

In this paper, we study the Bin Packing Problem with Conflicts and Item Fragmentation (BPPC-IF) which has applications in the delivery and storage of items that cannot be packed together. Given a set of items each with a certain size, the goal in BPPC-IF is to pack these items into a minimum number of fixed-capacity bins while not packing fragments of conflicting items into the same bin. We assume a size-preserving fragmentation, i.e., the total size of fragments of an item packed into the bins has to be equal to the item's original size. We first prove that BPPC-IF is still NP-hard even though items can be fragmented. Unlike the Bin Packing Problem with Item Fragmentation (BPPIF), we show that BPPC-IF does not necessarily admit optimal solutions with a special structure. Moreover, we show that preprocessing an instance with oversized items (items with size greater than bin capacity) by packing a fragment of such items with size equal to bin capacity to a single bin does not necessarily yield an optimal solution. Using this observation, we develop a lower bounding procedure. Finally, we propose a heuristic algorithm which sequentially packs items into the bins using the observation about the oversized items. Through an extensive computational study, we demonstrate the superior performance of the proposed solution approach over the existing algorithms in the literature. (C) 2020 Elsevier Ltd.
