Enhancers are short DNA cis-elements that can be bound by proteins(activators)to increase the possibility that transcription of a particular gene will occur.The Enhancers per-form a significant role in the formation of proteins and regulat-ing the gene transcription process.Human diseases such as can-cer,inflammatory bowel disease,Parkinson\'s,addiction,and schizophrenia are due to genetic variation in enhancers.In the current study,we have made an effort by building,a more robust and novel computational a bi-layered model.The representative feature vector was constructed over a linear combination of six features.The optimum Hybrid feature vector was obtained via the Novel Cascade Multi-Level Subset Feature selection(CM-SFS)algorithm.The first layer predicts the enhancer,and the secondary layer carries the prediction of their subtypes.The baseline model obtained 87.88%of accuracy,95.29%of sen-sitivity,80.47%of specificity,0.766 of MCC,and 0.9603 of a roc value on Layer-1.Similarly,the model obtained 68.24%,65.54%,70.95%,0.3654,and 0.7568 as an Accuracy,sensitiv-ity,specificity,MCC,and ROC values on layer-2 respectively.Over an independent dataset on layer-1,the piEnPred secured 80.4%accuracy,82.5%of sensitivity,78.4%of specificity,and 0.6099 as MCC,respectively.Subsequently,the proposed pre-dictor obtained 72.5%of accuracy,70.0%of sensitivity,75%of specificity,and 0.4506 of MCC on layer-2,respectively.The proposed method remarkably performed in contrast to other state-of-the-art predictors.For the convenience of most exper-imental scientists,a user-friendly and publicly freely accessi-ble web server@/bienhancer dot pythonany where dot com/has been developed.

Closely related to the safety and stability of power grids,stability analysis has long been a core topic in the elec-tric industry.Conventional approaches employ computational simulation to make the quantitative judgement of the grid sta-bility under dist
Reinforcement learning is about learning agent models that make the best sequential decisions in unknown en-vironments.In an unknown environment,the agent needs to explore the environment while exploiting the collected infor-mation,which usually forms a s
The data stream processing framework processes the stream data based on event-time to ensure that the request can be responded to in real-time.In reality,streaming data usu-ally arrives out-of-order due to factors such as network delay.The data stream pro
Lysine lipoylation plays vital roles in cell metabolism and redox processes.For example,removal of lipoylation will decrease pyruvate dehydrogenase activity and affect the citric acid cycle.Despite the important functions of lysine lipoylation,the mechani
Many key-value stores use RDMA to optimize the messaging and data transmission between application layer and the storage layer,most of which only provide point-wise op-erations.Skiplist-based store can support both point operations and range queries,but i
Node order is one of the most important factors in learning the structure of a Bayesian network(BN)for proba-bilistic reasoning.To improve the BN structure learning,we propose a node order learning algorithm based on the frequently used Bayesian informati
