Magnesium-related solid bases have long been considered catalysts with weak or medium basicity. Here we report the fabrication of Mg single-atom superbasicity for first time. A sublimation-migration-anchoring strategy is employed, in which net sublimated, transported by Ar, and trapped defective graphene (producing Mg1/G). Simulated experimental results demonstrate that single atoms are anchore...

The analysis of Serratia liquefaciens MG1 'luxAB insertion mutants that are responsive to N-butanoyl-L-homoserine lactone revealed that expression of lipB is controlled by the swr quorum-sensing system. LipB is part of the Lip exporter, a type I secretion system, which is responsible for the secretion of extracellular lipase, metalloprotease, and S-layer protein.

we propose to use a mathematical method based on stochastic comparisons of markov chains in order to derive performance indice bounds‎. ‎the main goal of this paper is to investigate various monotonicity properties of a single server retrial queue with first-come-first-served (fcfs) orbit and general retrial times using the stochastic ordering techniques‎.

Nowadays, authentication mechanism is widely applied to digital images to verify whether the received image is not a fake. In this paper, we propose a selfauthentication mechanism without any extra data to authenticate whether the area is modified by comparing the generated authentication code and hidden authentication code together. Also, the recovery ability is employed to the proposed scheme...

BACKGROUND Diabetic nephropathy is a serious complication of T1D (type one diabetes mellitus). Persistent hyperglycemia and subsequent hypomagnesemia is believed to develop kidney damage by activation of oxidative stress. We conducted this study to investigate the renoprotective effect of magnesium sulfate (MgSO4) on renal histopathology and oxidative stress in diabetic rats. METHODS The stud...

The present investigation deals with the bulk arrival M/G/1 retrial queue with impatient customers and modified vacation policy. The incoming customers join the virtual pool of customers called orbit if they find the server being busy, on vacation or in broken down state otherwise the service of the customer at the head of the batch is started by the server. The service is provided in k</em...

The short period variable star MG1-688432 has been discovered to exhibit occasional extremely high energy optical outbursts as 10^31 joules. Outbursts are typically of several hours duration. These events often highly structured, resembling sequential associated releases energy. Twenty years time sequence photometry is presented, indicating a basic sinusoidal light curve mean 6.65d, with some p...

This paper analyzes a renewal input  working vacations queue with change over times and Bernoulli schedulevacation interruption under (a,c,b) policy.The service and vacation times are exponentially distributed.The server begins service if there are at least c units in the queue and the service takes place in batches with a minimum of size a and a maximum of size b (a
