As naval operations move into coastal waters, the possible impact of sporadic blooms of bioluminescent organisms on clandestine operations is of increasing concern. One such bloom forming light producer is the ctenophore Mnemiopsis leidyi. This native-American comb jelly was first introduced into the Black Sea in 1982 where it caused the total collapse of the local fisheries. It has recently b...
A technique is presented for condensing a multi-degree-of-freedom flutter calculation so that similar flutter conditions are achieved with two degrees-of-freedom. Use is made of digital computer programmes, and the process is largely automatic. Examples of the application of the technique are given, and show that systems can often be reduced to two normal modes, or to two orthogonal combination...
A pressure plethysmograph for measuring respiratory volume in mice during exposure to virus aerosols is described. The respiratory frequency and tidal volume were measured, and from these data the minute ventilation was calculated. The mean respiratory frequency of adult, male mice was 255 per min; the mean tidal volume of 0.18 ml was inversely related to respiratory frequency. The standardized...

We propose a non-parametric approach for characterizing heterogeneous diseases in large-scale studies. We target diseases where multiple types of pathology present simultaneously in each subject and a more severe disease manifests as a higher level of tissue destruction. For each subject, we model the collection of local image descriptors as samples generated by an unknown subject-specific prob...
Insufficient or excess drug doses, due to unknown actual drug concentrations at the focus, are one of the main causes of chemotherapy failure for cancers. In this regard, the real-time monitoring of the release of anticancer drugs from nanoparticle drug delivery systems is of crucial importance, but it remains a critical and unsolved challenge. Herein, we report the proposal and development of ...
Upconversion nanophosphors (UCNPs) are extremely useful for analytical applications, since they display a high signal-to-noise ratio, and their photobleaching can be ignored. Herein, a novel upconversion nanocomposite composed of β-cyclodextrin (β-CD) derivative modified UCNPs and rhodamine B (RB) was prepared for the detection of cholesterol (Cho). The upconversion luminescence (UCL) emission ...
As proposed in the LUCIFER project, ZnSe crystals are attractive materials to realize scintillating bolometers aiming at the search for neutrinoless double beta decay of the promising isotope 82Se. However, the optimization of the ZnSe-based detectors is rather complex and requires a wide-range investigation of the crystal features: optical properties, crystalline quality, scintillation yields ...
In this paper we develop a model to describe the emission profile from randomly oriented dichroic dye molecules in a luminescent solar concentrator (LSC) waveguide as a function of incoming light direction. The resulting emission is non-isotropic, in contradiction to what is used in almost all previous simulations on the performance of LSCs, and helps explain the large surface losses measured i...
We present a structured light system to dynamically measure human chest wall motion for respiratory volume estimation. Based on a projection of an encoded color pattern and a few active markers attached to the trunk, respiratory volumes are obtained by evaluating the 3-D topographic changes of the chest wall in an anatomically consistent measuring region during respiration. Three measuring setu...
