High spatial and temporal resolutions are important advantages of optical imaging over other modalities. The recently developed spatial overlap modulation (SPOM) microscopy enables high resolution imaging by spatial modulation of double-beam overlap. However, SPOM suffers from bad temporal resolution and high system complexity. In this paper, we re-formulate the SPOM resolution theory and devel...

We compared the clinical, psychological and pharmacological characteristics of patients with familial migraine and patients with sporadic migraine. Five hundred and thirty consecutive new patients attending our Headache Center over a two-year period were involved in the study. The patients were divided into two groups: A. Familial migraine (famM)--at least one first-degree relative affected; B....

Cyclic nucleotides cAMP and cGMP are among the main molecules that control maturation of mammal oocytes. The in vitro simulated physiological oocyte (SPOM) method was used to model accumulation oocyte. In current study, we preincubated oocytes cows (not primed with FSH) modulators: N 6,2’-O-dibutyryladenosine 3’,5’-cyclomonophosphate (dbcAMP) 3-isobutyl-1-methylxanthine (IBMX). use SPOM increas...

I analyze stochastic patch occupancy models (SPOMs), which record habitat patches as empty or occupied. A problem with SPOMs has been that if the spatial structure of a heterogeneous habitat patch network is taken into account, the computational effort needed to analyze a SPOM grows as a power of 2n, where n is the number of habitat patches. I propose a computationally feasible approximation me...

Stochastic patch occupancy models (SPOMs) are a class of discrete time Markov chains used to model the presence/absence of a population in a collection of habitat patches. This class of model is popular with ecologists due to its ability to incorporate important factors of the habitat patch network such as connectivity and distance between patches as well as heterogeneity in patch characteristi...

First year programming has been consistently below the Faculty and University averages in SPOM (Student Perception Of Module) reports. An immersive learning style of delivery has been adopted in an attempt to improve student motivation and outcomes. This paper reports preliminary positive results.

Organic matter has an important role in biogeochemistry aquatic environments. This study investigated impact of suspended particulate organic (SPOM) on fluorescence signal mixtures three water types (river RW, sea SW, effluent wastewater WW) using (excitation-emission matrix, EEM) spectroscopy and parallel factor analysis (PARAFAC) multilinear regression. Four irradiation experiments (Expt-1, E...

This work demonstrates the efficiency of using linear statistical modelling for estimation of concentrations of various substances in lake water using remotely sensed multiand hyperspectral images together with extensive field measurements collected over Lake Erken in Sweden. A linear relationship was assumed between image data and the corresponding field measurements, and the transformation co...

The measurement and analysis of inherent optical properties (IOPs) of the main water constituents are necessary for remote-sensing-based water quality estimation and other ecological studies of lakes. This study aimed to measure and analyze the absorption and backscattering coefficients of the main water constituents and, further, to analyze their relations to the water constituent concentratio...

Kelp forests dominated by Macrocystis pyrifera are widely distributed in coastal waters from boreal, temperate and subantarctic regions. This widespread distribution may result regional differences food web structure functioning. In northern regions, where most studies on kelp forest benthic webs have been conducted, grazing is a well-documented phenomenon can lead to the overgrazing of M. sea ...
