Natlog: a Lightweight Logic Programming Language with a Neuro-symbolic Touch

Description: Article that introduces Natlog, a lightweight Logic Programming language, sharing Prolog's unification-driven execution model, but with a simplified syntax and semantics. The authors' proof-of-concept Natlog implementation is tightly embedded in the Python-based deep-learning ecosystem with focus on content-driven indexing of ground term datasets. As an overriding of the authors symbolic indexing algorithm, the same function can be delegated to a neural network, serving ground facts to Natlog's… more

Thermally Tunable Acoustic Beam Splitter Based on Poly(vinyl alcohol) Poly(N-isopropylacrylamide) Hydrogel

Description: Article demonstrating a thermally tunable acoustic beam splitter using a poly(vinyl alcohol) poly(N-isopropylacrylamide) hydrogel (PVA-pNIPAM). The nature of PVA-pNIPAM hydrogel offers exceptional temperature-dependent physical properties due to its phase transition around its lower critical solution temperature. The acoustic impedance of the hydrogel can be tuned below, above, or matched to that of water by changing the environmental temperature. An acoustic wave propagating in water can be sp… more

Developmental programming of DNA methylation and gene expression patterns is associated with extreme cardiovascular tolerance to anoxia in the common snapping turtle

Description: This article explores DNA methylation's role in the regulation of gene expression in reptiles. Results show that embryonic hypoxia programs DNA methylation and gene expression patterns and that these changes are associated with enhanced cardiac anoxia tolerance in snapping turtles later in life.

A gene-editing/complementation strategy for tissue-specific lignin reduction while preserving biomass yield

Description: This article develops a method, using a single DNA construct that uses CRISPR–Cas9 gene editing to knock-out expression of an endogenous gene of lignin monomer biosynthesis while at the same time expressing a modified version of the gene’s open reading frame that escapes cutting by the Cas9 system and complements the introduced mutation in a tissue-specific manner. This method is applicable to any plant species in which transformation and gene editing are feasible and validated vessel-specific … more

Who Is Purged? Determinants of Elite Purges in North Korea

Description: This article argues that elite purges in consolidated dictatorships have a different purpose and logic. Dictators, who have consolidated their position, seek to maximize the efficiency of rule by making the elite obedient through purges. For this purpose, dictators carefully select the purge target by considering various factors. To test this theory, the article examines the pattern of elite purges in North Korea based on an original individual-level dataset, which contains the personal backgro… more
