Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, EarlyView.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

Vertical Distribution of Teredo norvegica

Nature, 1953
THE literature dealing with the wood-boring bivalve, Teredo, is extensive. The majority of investigations, however, have dealt with floating structures and little attention has been paid to the problem of vertical distribution. During a recent investigation into an attack of T.

VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

Bulletin of Economic Research, 2006
The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger

A vertical distribution LTCC duplexer

2011 12th International Conference on Electronic Packaging Technology and High Density Packaging, 2011
A vertical distribution low temperature cofired-ceramic (LTCC) duplexer is presented in this paper. It is constructed using two band pass filters based on lump-element components. In order to reduce the size, we use vertical structure to arrange the two band pass filters. The two band pass filters are both true third-order topology and T type.

Distributing vertices on Hamiltonian cycles

Journal of Graph Theory, 2011
AbstractLet G be a graph of order n and 3≤t≤n/4 be an integer. Recently, Kaneko and Yoshimoto [J Combin Theory Ser B 81(1) (2001), 100–109] provided a sharp δ(G) condition such that for any set X of t vertices, G contains a hamiltonian cycle H so that the distance along H between any two vertices of X is at least n/2t.

Distributed vertical line array receiver.

The Journal of the Acoustical Society of America, 2011
A distributed vertical line array (DVLA) receiver able to span the water column in water up to 6000 m deep has been developed to allow both modal and ray-based analyzes of acoustic propagation. The DVLA is made up of distributed, self-recording hydrophones with timing and scheduling provided by a small number of central controllers, called D-STARs. The
