Partial clones containing all Boolean monotone self-dual partial functions
, 2015 The study of partial clones on $\mathbf{2}:=\{0,1\}$ was initiated by R. V. Freivald. In his fundamental paper published in 1966, Freivald showed, among other things, that the set of all monotone partial functions and the set of all self-dual partial functions are both maximal partial clones on $\mathbf{2}$. Several papers dealing with intersections of

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities
Advanced Science, EarlyView.T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Zhejiang Daxue xuebao. Lixue ban, 2018 针对已有方法在求解布尔e偏导数时只能解决小规模电路的问题，提出了一种基于逻辑函数不相交运算的大函数高阶布尔e偏导数的求解算法.该方法将逻辑函数转化为不相交乘积项的集合，用逻辑函数的不相交运算替代布尔e导数运算中的逻辑“与”运算；并将不包含待求导变量的乘积项拆分出来，不参与布尔e导数运算，以达到降低算法复杂度、提高算法速度的目的.提出的算法用C语言编程实现，并用MCNC测试电路进行了测试.实验结果显示，本算法能快速实现大函数高阶布尔e偏导数的求解，求解效率与参与不相交运算的乘积项数量有关 ...

Advanced Science, EarlyView.A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...

Negation and presupposition, truth and falsity
Studies in Logic, Grammar and Rhetoric, 2018 There are many kinds of negation and denial. Perhaps the most common is the Boolean negation not that applies to propositions-in-extension, i.e. truth-values.
