Coral diseases have caused a substantial decline in the biodiversity and abundance of reef-building corals. To date, more than 30 distinct diseases of scleractinian corals have been reported, which cause progressive tissue loss and/or affect coral growth, reproductive capacity, recruitment, species diversity and the abundance of reef-associated organisms. While coral disease research has increa...

We study roughness scaling of the outer surface and the internal porous structure of deposits generated with the three-dimensional bidisperse ballistic deposition (BBD), in which particles of two sizes are randomly deposited. Systematic extrapolation of roughness and dynamical exponents and the comparison of roughness distributions indicate that the top surface has Kardar-Parisi-Zhang (KPZ) sca...

Cytochrome P450 1B1 (CYP1B1) and catechol-O-methyltransferase (COMT) are important estrogen-metabolizing enzymes that may affect breast cancer risk. Few studies have directly measured the expression of CYP1B1 and COMT genes in breast tissue samples. The subjects in this study were a subgroup of participants of the Shanghai Breast Cancer Study including 64 patients diagnosed with breast cancer a...

The cerebellum is known to be critical for accurate adaptive control and motor learning. We propose here a mechanism by which the cerebellum may replace reflex control with predictive control. This mechanism is embedded in a learning rule (the delayed eligibility trace rule) in which synapses onto a Purkinje cell or onto a cell in the deep cerebellar nuclei become eligible for plasticity only a...

background nowadays, adsorption techniques are widely used to remove certain classes of pollutants from water. objectives the aim of this study was to remove ametryn from water solutions by natural zeolite nanoparticles from the semnan region of iran. materials and methods for this purpose zeolite nanoparticles were synthesized from natural zeolite using planetary ball-mill. the zeolite nanopar...

A mixed-mode very large scale integration (VLSI) processor for acoustic transient classification performs a running correlation between a time-frequency decomposed analog input signal and a corresponding template. Differential encoding of the inputs allows simplification of the multiply-and-accumulate operations, operating on binary templates and positive-valued inputs, implemented in current m...

Bronchoscopic balloon dilation (BBD) is a useful method of treating tracheobronchial stenosis. Tracheobronchial stenosis in adults can arise from benign or malignant disease. Benign stenosis causes include sarcoidosis, tuberculosis, Wegener’s granulomatosis, trauma, berylliosis, and foreign body reaction. Furthermore, it can arise after prolonged endotracheal intubation, after sleeve resection ...

Between 1977 and 1980, 854 biopsied cases of benign breast disease (BBD) and 755 matched surgical and 723 matched neighborhood controls subjects were interviewed in Israel by using a detailed food frequency questionnaire. Cases were classified according to degree of ductal atypia (Black-Chablon grading system). Women with atypic lesions (grades greater than or equal to 3) reported a higher inta...

Using basic terms, BBD chips create a analog representation of the signal by storing an electrical charge that is passed along the “bucket brigade”. The charge is passed at a rate determined by the clock and the magnitude of charge stored at any given instant is an analog value, unlike a digital delay where the amplitude is assigned to a digital value that has discrete steps. At first glance, t...

As the University of Minnesota Biocatalysis/Biodegradation Database (UM-BBD, http://umbbd.ahc.umn.edu/) starts its second decade, it includes information on over 900 compounds, over 600 enzymes, nearly 1000 reactions and about 350 microorganism entries. Its Biochemical Periodic Tables have grown to include biological information for almost all stable, non-noble-gas elements (http://umbbd.ahc.um...
