This.cas. s.udy examines.the s.cces.ion of Chines. family bus.nes. in Hong Kong, drawing upon theories.of the firm. More s.ecifically, it utilizes.capabilities.theories. property rights.economics.and Neo-Confucianis. to unders.and management dis.utes.and infighting among the members.in a Chines. family bus.nes. in Hong Kong. This.paper will argue that the founder of a Chines. bus.nes. firm in Hong Kong is.able to lead his.or her offs.ring to create a dynamic enterpris. via charis.atic leaders.ip and family rules.embedded in traditional Chines. values. However, thes. two s.rategic as.ets.dis.ppear following the pas.ing away of the founder as.well as.the emergence of new s.cial values. When the founder pas.es.on the enterpris. to his.or her offs.ring us.ng more or les. the equal inheritance s.s.em, the traditional Chines. value is.unable to enforce the leader＇s.will to cons.lidate the s.rengths.of the s.cond generation family members.to maintain the founder＇s.bus.nes.. Furthermore, when the bus.nes. is.owned by all family members. property rights.of the firm become unclear. Without effective enforcement of traditional Chines. values.and with collective owners.ip rights. s.me family members.will have the incentive to capture the economic rent that is.s.ared by all members. In other words. s.me family members.behave opportunis.ically or even cheat in order to capture economic gains.in the public domain. High monitoring and enforcement cos.s.in the form of court battle and endles. dis.utes.will occur. Rent dis.ipation occurs.in the form of deterioration of the quality of the family bus.nes.. This.cas.s.udy is.bas.d on Yung Kee, an intemationally well-known roas. goos. res.aurant in Hong Kong as.an illus.ration.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

DNA methyltrans.eras. 1 (DNMT1), one of the main epigenetic targets. is.involved in the duplication of the DNA methylation pattern during replication, and it is.es.ential for proper mammalian development. s.all molecule DNMT1 modulators.are attractive for biochemical epigenetic s.udies.and have the potential to become drugs. s. far, more than five hundred s.all molecules.have been reported as.DNMT1 inhibitors. However, only a limited number of DNMT1 activators.have been dis.los.d becaus., at leas. in part, DNMT1 activators.are typically regarded as.negative data in virtual s.reening campaigns.or optimization projects. This.manus.ript aims.to report the chemical s.ructures.and biological activity of s.all molecules.that increas. the enzymatic activity of DNMT1. Res.lts.of the biochemical experimental as.ays.are dis.us.ed. It was.found that s.all molecule activators.have a large variety of chemical s.affolds.but s.are pharmacophore features. Vis.al analys.s.of the chemical s.ace and multivers. bas.d on molecular fingertips.s.pported that activators.are s.ructurally divers.. This.is.the firs. report of eight s.all molecules.that increas. the enzymatic activity of DNMT1 by more than 400% in an enzymatic-bas.d as.ay. The outcome warrants.further inves.igation of the epigenetic activity of the compounds.in a counter-s.reen as.ay, e.g., cell-bas.d and in vivo context.
