Here we analyze a simple cascade model of stochastic gene expression, which assumes that the upstream (input) gene is expressed in a constitutive manner whereas the downstream (output) gene is expressed in a bursty fashion via a two-state model, and that the former regulates the latter via transcription factors (products of the former). By large scale sampling in the space of model parameters, we find that the output distributions can exhibit diverse patterns such as unimodal, bimodal or trimodal modes, depending on the regulation way (positive or negative). These patterns, which are different from those in the case of no regulation, are independent of the choice of parameter values and hence qualitatively invariant. Diverse expression patterns resulting from signal response would be important for cell fate decisions and utilized by cells for a better survival in complex environments.</div></div>","PeriodicalId":10340,"journal":{"name":"Chinese Journal of Physics","volume":"98 ","pages":"Pages 125-136"},"PeriodicalIF":4.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantum homomorphic encryption (QHE) offers significant advantages in handling privacy-preserving computations. However, given the current limitations of quantum resources, developing efficient and feasible QHE-based protocols for PSI and PSU computations remains a critical challenge. In this work, a novel quantum private set intersection and union cardinality protocol is proposed, accompanied by the corresponding quantum circuits. Based on quantum homomorphic encryption, the protocol allows the intersection and union cardinality of users’ private sets to be computed on quantum-encrypted data with the assistance of a semi-honest third party. By operating on encrypted quantum states, it effectively mitigates the risk of original information leakage. Furthermore, the protocol requires only simple Pauli and CNOT operations, avoiding the use of complex quantum manipulations (e.g., <span><math><mi>T</mi></math></span> gate and phase rotation gate).

In this work, interface charge modulation effect in HJ-DGVTFETs with integrated nano compatibility biosensors is considered for reliable, precise, and fast recognition of antigens in body fluids using blood serum rather than saliva. The suggested biosensor has a double cavity etched under the double gate structure to immobilize bioanalyte.
