AX-1 is a marker for postmitotic granule cells that start to extend processes in the inner EGL 6,8
No full textDouble-staining of sagittal sections taken from HH35 brains demonstrated that AX-1 (a) labeled young postmitotic granule cells in the inner EGL (iEGL) that were not yet NgCAM-positive (b; merged in c). Therefore, an overlap between AX-1 and NgCAM was only found in the ML, where older granule cells are located (c). Double staining for AX-1 (d) and NrCAM (e) revealed that there was less overlap between AX-1 and NrCAM (f) compared to AX-1 and NgCAM (c). Similarly, there was little overlap (i) between AX-1 (g) and Contactin/F11 (h), consistent with previous reports [39]. AX-1 is expressed in postmitotic granule cells but not in granule cell precursors in the outer EGL (oEGL) that are still proliferating (j). Precursors and postmitotic granule cells are identified by Pax6 staining (k) [42]. The overlap between AX-1 and Pax6 is restricted to the inner EGL (l). AX-1 reactivity (m) mostly overlapped with RMO270 reactivity (n), demonstrating that the vast majority of the neurofilament signal at HH35 was generated by granule cells (o).

Solution for Matrix Equation AX-YB=C
No full textThe inverse of a matrix A can only exist if A is nonsingular. This is an important theorem in linear algebra, one learned in an introductory course. In recent years, needs have been felt in numerous areas of applied mathematics for some kind of inverse like matrix of a matrix that is singular or even rectangular. To fulfill this need, mathematicians discovered that even if a matrix was not invertible, there is still either a left or right sided inverse of that matrix. The inverse moore Penrose is an inverse matrix type denoted by A(1). The inverse moore penrose is an extension of the inverse matrix concept. complex matrices will be used to find matrix inverses. Matrix m×n field F can write as Cm×n with A(1) g-invers of A, the matrix statisfying the equation AA(1)A=A. A necessary and suffient conditions is established for solvability of the matrix equation AX-YB=C. Where matix A,B, and C are giving by equation, we can find the solutions by using Penrose equation existence and construction of -inverse to find matrix X and Y satisfying the equation AX-YB=C. Substitute the matrix and the matrix to the equation AX-YB=C so that it is proven that the results of AX-YB are matrix C
Theoretical investigation on radiation tolerance of Mn+1 AX(n) phases
No full textTernary M(n + 1)AX(n) phases with layered hexagonal structures, as candidate materials used for next-generation nuclear reactors, have shown great potential in tolerating radiation damage due to their unique combination of ceramic and metallic properties. However, Mn + 1AXn materials behave differently in amorphization when exposed to energetic neutron and ion irradiations in experiment. We first analyze the irradiation tolerances of different M(n + 1)AX(n) (MAX) phases in terms of electronic structure, including the density of states ( DOS) and charge density map. Then a new method based on the Bader analysis with the first-principle calculation is used to estimate the stabilities of MAX phases under irradiation. Our calculations show that the substitution of Cr/V/Ta/Nb by Ti and Si/Ge/Ga by Al can increase the ionicities of the bonds, thus strengthening the radiation tolerance. It is also shown that there is no obvious difference in radiation tolerance between Mn (+ 1)AC(n) and Mn (+ 1)AN(n) due to the similar charge transfer values of C and N atoms. In addition, the improved radiation tolerance from Ti3AlC2 to Ti2AlC ( Ti3AlC2 and Ti2AlC have the same chemical elements), can be understood in terms of the increased Al/TiC layer ratio. Criteria based on the quantified charge transfer can be further used to explore other M(n + 1)AX(n) phases with respect to their radiation tolerance, playing a critical role in choosing appropriate MAX phases before they are subjected to irradiation in experimental test for future nuclear reactors
Modification of HSA by AX and AX-B.
No full text<p>(A) HSA was incubated in the presence of the indicated concentrations of Ax or Ax-B and adduct formation was assessed by western blot and detection with an anti-AX antibody (AO3.2) or with HRP-streptavidin. Exposure times were 5 minutes for AX and one second for AX-B detection, respectively. (B) HSA was incubated with AX or AX-B at 0.5 mg/ml for 16 h at 37°C. Aliquots of the incubation mixture containing the indicated amounts of total protein were analyzed by SDS-PAGE and adducts formed were detected as above. Exposure times were 2 minutes for AX and one second for AX-B detection, respectively.</p

Competition between AX and AX-B for modification of HSA.
No full text<p>(A) HSA was incubated overnight with a 9-fold molar excess of AX or AX-B in bicarbonate buffer and detection of adducts was achieved by western blot with an anti-AX antibody (AO3.2) or with HRP-streptavidin, as indicated. (B) HSA was incubated in the absence or presence of AX-B, as above, followed by an overnight incubation with AX. Binding of AX was assessed by western blot with AO3.2 antibody. (C) HSA was incubated for 2 h with 80 μM AX-B, after a 16 h pre-incubation with the indicated concentrations of AX, expressed in molar excess with respect to AX-B. Aliquots of the incubation containing 2 μg of protein were subjected to SDS-PAGE and transfer, and incorporation of AX-B was assessed by detection with HRP-streptavidin.

No full textFor a given ordered units triple , the solutions to the quaternion matrix equations and , , where is the conjugate transpose of , and , , are discussed. Some new real representations of quaternion matrices are used, which enable one to convert -conjugate (transpose) matrix equations into some real matrix equations. By using this idea, conditions for the existence and uniqueness of solutions to the above quaternion matrix equations are derived. Also, methods to construct the solutions from some related real matrix equations are presented
