SMARANDACHE NON-ASSOCIATIVE RINGS [PDF]
, 2002 An associative ring is just realized or built using reals or complex; finite or infinite by defining two binary operations on it. But on the contrary when we want to define or study or even introduce a non-associative ring we need two separate algebraic ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Cyclic codes over finite rings
Discrete Mathematics, 1997 A linear left code \(C\) of length \(n\) over a finite ring \(R\) is a submodule of \({}_R R^n\). It is called splitting if it is a direct summand of \({}_R R^n\). \(C\) is a cyclic linear left code if it is a left ideal of \(R[x]/(x^n -1)\) and it is called splitting if it is a direct summand of \({}_R (R[x]/(x^n -1))\).

Codes Over Matrix Rings for Space-Time Coded Modulations [PDF]
IEEE Transactions on Information Theory, 2012 It is known that, for transmission over quasi-static MIMO fading channels with n transmit antennas, diversity can be obtained by using an inner fully diverse space-time block code while coding gain, derived from the determinant criterion, comes from an appropriate outer code.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Bijective soft rings with applications
Journal of New Results in ScienceIn recent years, soft sets have been widely used in many important decision-making real-life problems. In this paper, observing the usage of soft sets in such kind of vital problems, we have introduced the bijective-unitary bijective soft rings. Firstly,

Exceptional Sequences over Graded Cohen-Macaulay Rings [PDF]
, 1999 The concept of exceptional sequences was developed by Gorodentsev and Rudakov in [3] and generalized by Bondal in [1].

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Codes over integer residue rings
Information and Control, 1975 Using module theoretic techniques, a linear code is defined as a submodule of \(Z_mC_n\), the group ring of the cyclic group \(C_n\) of order \(n\) over the ring of integers modulo \(m\), \(Z_m\). A cyclic code is defined as an ideal in \(Z_mC_n\). Natural analogs to Hamming, Reed-Solomon and BCH codes are defined over \(Z_m\) and some of the ring ...
