A Generative Neuro‐Symbolic AI for Protein Sequence Design

open access: yesAdvanced Science, EarlyView.
We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Digital Modeling Method of Variable Ratio Rack based on Boolean Subtraction Operation and Curve Fitting Technology

open access: yesJixie chuandong, 2016
Based on the Boolean subtraction operation and curve fitting technology,a digital modeling method for variable ratio rack is put forward. This method,to a certain extent,makes up for the disadvantages that the Boolean subtraction operation modeling ...

Completeness for the coalgebraic cover modality [PDF]

open access: yesLogical Methods in Computer Science, 2012
We study the finitary version of the coalgebraic logic introduced by L. Moss. The syntax of this logic, which is introduced uniformly with respect to a coalgebraic type functor, required to preserve weak pullbacks, extends that of classical propositional

Spatially Encoded Protocell Network for Non‐Cascaded Parallel Biocomputation

open access: yesAdvanced Science, EarlyView.
A non‐cascaded, hydrogel‐based proteinosome computational platform is developed, in which redox‐responsive proteinosomes serve as local computing units within a shared reaction–diffusion field. Reductant inputs, countered by an auxiliary glucose gradient, regulate spatially patterned proteinosome disruption, and generate population‐level boundaries ...

A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

open access: yesAdvanced Science, EarlyView.
A cascaded dual‐AND logic DNA nanocircuit is engineered to respond to three tumor‐specific signals in a sequential manner: extracellular acidic pH, membrane‐overexpressed nucleolin (NCL), and intracellular glutathione (GSH). This programmable system selectively releases siPARP1 in glioblastoma (GBM), effectively silencing PARP1 and reversing TMZ ...

The Sheffer stroke operation reducts of basic algebras

open access: yesOpen Mathematics, 2017
In this study, a term operation Sheffer stroke is presented in a given basic algebra 𝒜 and the properties of the Sheffer stroke reduct of 𝒜 are examined. In addition, we qualify such Sheffer stroke basic algebras.

The Boolean pivot operation M-matrices, and reducible matrices [PDF]

open access: yes, 1993
Let A be a Boolean n × n matrix, and let G = (N, U) be the corresponding diagraph, where N ≔ {1,…,n} is the set of vertices and U ⊂ N × N is the set of arcs of G.
