Durability of Resinous Woods

Natural Durability of Citharexylum spinosum and Morus alba Woods Against Three Mold Fungi

The natural durability of wood to mold fungi was tested under laboratory conditions with locally sourced Citharexylum spinosum and Morus alba woods. The mold fungi were Penicillium selerotigenum, Paecilomyces variotii, and Aspergillus niger. Changes in surface elemental composition were evaluated with energy dispersive X-ray spectroscopy (EDX) and the biodeterioration of wood surfaces by scanni...

Deep Woods

Recent theoretical studies indicate that deep architectures [4, 2] are needed to efficiently model complex distributions and to achieve better generalization performance on challenging recognition tasks. The belief that additional levels of functional composition will yield increased representational and modeling power is not new [13, 9, 16]. In practice, learning in deep architectures had prov...

CRISPRing into the woods

The CRISPR/Cas9 technology is a welcome breakthrough for genome editing, owing to its precision, efficiency, versatility and ease of adoption. We recently reported the first application of CRISPR/Cas9 for biallelic mutations in stably transformed Populus, extending the species range of this powerful technology to woody perennials. An underappreciated obstacle in genome editing of outcrossing sp...

Trees outside woods

Woods Hole Gceanocraphsc Institution

The theory of internal tidal waves is briefly reviewed in order to demonstrate the importance of simultaneous observations at different positions. After a description of the expectancy test it is shown that a reasonably high probability exists that the internal tidal oscillations found at Meteor Station 385 in the temperature observations are real and not purely formal results of the harmonic a...
