Primes in the doubly stochastic circulant matrices [PDF]
, 2007 正矩阵半环中素元的分类在控制与系统论中有重要的应用．已经知道在正矩阵、双随机矩阵和双随机循环矩阵中素元分类的一些结果。将应用任一n阶双随机循环矩阵都可被唯一地表示为移位的n-1次一元多项式这一事实,提出了把双随机循环矩阵中的素元分类问题简化为解双随机循环矩阵上的一个方程的方法．由此,进一步给出了判别具有更大位数的n阶双随机循环矩阵是否是素元的一些结果．The classification of primes in the semi-ring of the positive matrices is of ...

Even and odd diagonals in doubly stochastic matrices [PDF]
, 2008 The existence of even or odd diagonals in doubly stochastic matrices depends on the number of positive elements in the matrix. The optimal general lower bound in order to guarantee the existence of such diagonals is determined, as well as their minimal ...

AI‐Designed Cyclic Peptides Enable Controllable Modulation of the CD28 Immune Checkpoint
Advanced Science, EarlyView.AI‐designed cyclic peptides enable controllable modulation of the CD28 immune checkpoint through reversible disruption of CD28‐CD80/CD86 interactions. The lead peptide, CIP‐3, suppresses T‐cell activation without intrinsic agonist activity, demonstrates dose‐dependent efficacy in a murine colitis model, and attenuates inflammatory cytokine production ...

A problem of Mirsky concerning nonsingular doubly stochastic matrices [PDF]
, 1972 The paper presents a new constructive proof of a theorem of Hardy, Littlewood, and Polya relating vector majorization and doubly stochastic matrices. Conditions on the vectors which guarantee that the corresponding matrices will be direct sums are given.

Advanced Science, EarlyView.Fangchinoline is identified as a small‐molecule DNGR‐1 modulator that enhances dendritic‐cell cross‐presentation of tumor antigens. By engaging DNGR‐1 and activating Syk–Nox2 signaling, it promotes phagosomal ROS, antigen escape, MHC‐I presentation, and CD8+ T‐cell priming, thereby strengthening antitumor immunity and sensitizing tumors to PD‐1 ...

A note on eigenvalues location for trace zero doubly stochastic matrices [PDF]
, 2015 Some results on the location of the eigenvalues of trace zero doubly stochastic matrices are provided. A result similar to that provided in [H. Perfect and L. Mirsky. Spectral properties of doubly–stochastic matrices.

Advanced Science, EarlyView.Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

Lih Wang's and Dittert's conjectures on permanents
Special MatricesLet Ωn{\Omega }_{n} denote the set of all doubly stochastic matrices of order nn. Lih and Wang conjectured that for n≥3n\ge 3, per(tJn+(1−t)A)≤t\left(t{J}_{n}+\left(1-t)A)\le tperJn+(1−t){J}_{n}+\left(1-t)perAA, for all A∈ΩnA\in {\Omega }_{n} and all t ...

Products of basic doubly stochastic matrices over a field [PDF]
, 1976 It is shown that if n⩾3, then every doubly stochastic matrix of order n over a field F is a product of doubly stochastic matrices with exactly two nonzero off- diagonal entries if and only if the characteristic of F is not 2 and F has more than three ...
