Neural prosthesis for the therapy of low back pain
Miler Vera,Bijeli? Goran,Schwirtlich Laszlo
Journal of Automatic Control , 2008, DOI: 10.2298/jac0802093m
Abstract: We present methods to treat Low Back Pain (LBP) with electrical stimulation. The conventional method of treating LBP with electrical stimulation is based on mechanisms of reduction of pain. The method that we suggest uses electrical stimulation of trunk muscles at motor suprathreshold level synchronized with exercising of the trunk muscles. The hypothesis was that the combination of voluntary activity augmented with electrical stimulation would lead to higher levels of recovery of postural control and thereby, reduction of LBP. The electrical stimulation in this treatment was delivered with the lumbar belt with eight pairs of electrodes named Stimbelt. The outcome measures included: a Visual Analogue Scale (VAS), the Oswestry LBP disability questionnaire, the SF-12 health survey, and Manual Muscle Test (MMT). We specifically address the selection of the most appropriate statistical tests for the analysis of results. The analysis of the results of the clinical study indicates significant benefits of the addition of the Stimbelt to the conventional therapy.

Application of SEM/EDS to environmental geochemistry of heavy metals
Milo? Miler,Mateja Gosar
Geologija , 2009,
Abstract: Heavy metals represent a ubiquitous constituent of the near-surface environment, present in widely varyingconcentrations that typically have little impact on human behaviour and health. However, the mining of metals anduse of these metals in industrial processes has produced significant anthropogenic inputs of metals to both localand global environments. As such, a rigorous overview of the current accumulation of heavy metals and knowledgeof mineralogy of heavy metal-bearing phases is important for understanding their stability, solubility, mobility,bioavailability and toxicity. These data are of fundamental importance for environmental risk assessment and evaluationof future scenarios. Since conventional geochemical analyses provide limited information, other analyticalmethods have to be utilized for the characterisation of heavy metal-bearing phases. Significant analytical methodfor identification and characterisation of heavy metals in environmental media is a scanning electron microscopecoupled with energy dispersive X-ray spectrometer (SEM/EDS), an apparatus for qualitative and semi-quantitative chemical analysis at microne level, newly introduced to Geological Survey of Slovenia. Use of SEM/EDS was already introduced to environmental studies world-wide. In Slovenia, SEM/EDS analyses of environmental media werefirstly carried out on the Me a River stream sediments and snow deposits from Ljubljana urban area.Heavy metal-bearing phases in the Me a River stream sediments were apportioned to three source areas: Me ica mining/smelting area (geogenic-technogenic origin), Ravne ironworks area (technogenic origin) and the Me a River catchment area (geogenic origin), which corresponds to data obtained by conventional geochemical and multivariate statistical methods. Airborne particles, identified in urban snow deposits, were interpreted as geogenic particles, represented by fragments of heavy metal-bearing minerals, and technogenic particles that originate from combustion of solid and liquid fuels, iron and steel melting processes and road traffic emissions.SEM/EDS proved to be a very useful analytical method for the study of heavy metal-bearing phases and characterisation according to their sources and genesis.
Self Containment, a Property of Modular RNA Structures, Distinguishes microRNAs
Miler T. Lee,Junhyong Kim
PLOS Computational Biology , 2008, DOI: 10.1371/journal.pcbi.1000150
Abstract: RNA molecules will tend to adopt a folded conformation through the pairing of bases on a single strand; the resulting so-called secondary structure is critical to the function of many types of RNA. The secondary structure of a particular substring of functional RNA may depend on its surrounding sequence. Yet, some RNAs such as microRNAs retain their specific structures during biogenesis, which involves extraction of the substructure from a larger structural context, while other functional RNAs may be composed of a fusion of independent substructures. Such observations raise the question of whether particular functional RNA substructures may be selected for invariance of secondary structure to their surrounding nucleotide context. We define the property of self containment to be the tendency for an RNA sequence to robustly adopt the same optimal secondary structure regardless of whether it exists in isolation or is a substring of a longer sequence of arbitrary nucleotide content. We measured degree of self containment using a scoring method we call the self-containment index and found that miRNA stem loops exhibit high self containment, consistent with the requirement for structural invariance imposed by the miRNA biogenesis pathway, while most other structured RNAs do not. Further analysis revealed a trend toward higher self containment among clustered and conserved miRNAs, suggesting that high self containment may be a characteristic of novel miRNAs acquiring new genomic contexts. We found that miRNAs display significantly enhanced self containment compared to other functional RNAs, but we also found a trend toward natural selection for self containment in most functional RNA classes. We suggest that self containment arises out of selection for robustness against perturbations, invariance during biogenesis, and modular composition of structural function. Analysis of self containment will be important for both annotation and design of functional RNAs. A Python implementation and Web interface to calculate the self-containment index are available at http://kim.bio.upenn.edu/software/.
Triassic and Jurassic beds in Krim Mountain area (Slovenia)
Milo? Miler,Jernej Pav?i?
Geologija , 2008,
Abstract: The Krim Mountain and its surroundings are characterized by Upper Triassic to Middle Jurassic rocks, which were deposited on the northern margin of the Dinaric Carbonate Platform. Upper Triassic beds are represented by Main dolomite that exhibits supra- to subtidal Lofer facies. The uppermost Triassic is characterized by approximately 40 m thick horizon of dolomitic breccia. Upper Triassic beds pass gradually into Lower Liassic dolomitic breccia, coarse-grained dolomite and micritic limestone. Presence of dolomitic breccias and absence of supra-intertidal sedimentary structures indicate sea-level rise. Middle Liassic beds consist of oolitic-oncolitic and lithiotid limestones deposited in alternating restricted lagoonal and open shallow-water environment. Upper Liassic beds are characterized by oolitic-oncolitic limestones, bituminous dolomitized limestones and dolomitic breccia deposited in high-energy shallow-water environment. Middle Jurassic beds consist of oolitic, oolitic-oncolitic and micritic limestones, formed predominantly in high-energy subtidal environment.
Characterisation of presumed meteorite from Trbovlje
Milo? Miler,Mateja Gosar,Milo? Marki?
Geologija , 2011,
Abstract: The main objective of this study was to identify and characterise a specimen of presumed meteorite, supposedly found in 1947 while crushing gangue material from an open-pit coal mining site in Trbovlje. The presumed meteorite was characterised according to its physical properties, chemical and mineral composition using EDSanalysis. Based on macroscopic characteristics and physical properties, such as external features, magnetism and density, and reaction with diluted HCl, it was established that the specimen is not a meteorite but a concretion that contains calcite. SEM/EDS analysis showed that the studied material was compositionally homogeneous. It consists predominantly of calcite, gypsum and iron sulphide. The prevailing mineral is calcite, which forms irregular grains.Iron sulphide occurs as pyrite (or marcasite), which forms thin coatings rimming calcite grains, while gypsum formsthin transitional layers between calcite grains and pyrite or marcasite crusts as a result of reaction between ironsulphide oxidation products and calcite. The matrix between grains mostly consists of very fine-grained mixture of iron sulphide, calcite, gypsum and iron sulphide oxidation products, however, fields of pure gypsum were also found between some grains. According to the composition of the concretion, it can be assumed that the specimen isa pyrite- and/or marcasite- carbonate concretion, perhaps coal ball, which most probably formed by mineralisation within peat in the early stage of coal genesis in the Trbovlje formation.
The use of SEM/EDS method in mineralogical analysis of ordinary chondritic meteorite
Milo? Miler,Ur?a Curk,Breda Mirti?
Geologija , 2009,
Abstract: The aim of this study was to evaluate the potential of scanning electron microscopy coupled with energy dispersiveX-ray spectroscopy (SEM/EDS) for determination of mineral phases according to their stoichiometry and assessment of mineral composition of ordinary chondritic meteorite. For the purposes of this study, H3 type ordinary chondritic meteorite Abbott was selected. SEM/EDS allows identification and characterisation of mineralphases, whose size is below the resolution of an optical microscope. Mineral phases in chondrules and interstitial matrix were located in backscattered electron (BSE) mode and were assessed from atomic proportions of constituent elements, obtained by the EDS analysis. SEM/EDS analyses of mineral phases showed that Abbott meteorite is characterised by Fe-rich (Fe, Ni)-alloy kamacite, Fe-sulphide troilite or pyrrhotite, chromite, Mg-rich olivine, orthopyroxene bronzite or hypersthene, clinopyroxene Al-diopside, acid plagioclase oligoclase, accessory mineral chlorapatite and secondary minerals Fe-hydroxides (goethite or lepidocrocite). Results of semi-quantitative analyses confirmed that most of analysed mineralphases conform well to stoichiometric minerals with minor deviations of oxygen from stoichiometric proportions. Comparison between mineral phases in chondrules and interstitial matrix was also performed, however it showed no significant differences in elemental composition.Differences in chemical composition between minerals in interstitial matrix and chondrules are sometimes too small to be discernedby the SEM/EDS, therefore knowledge of SEM/EDS capabilities is important for correct interpretation of chondrite formation.

Second Language Acquisition: Reconciling Theories  [PDF]
Vera Menezes
Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.37050
Abstract:

This article argues that previous attempts to explain SLA should not be disregarded. Instead, when they are put together, they provide a broader and deeper view of the acquisition process. There is evidence to support the claim that second language acquisition (SLA) is a complex adaptive system due to its inherent ability to adapt to different conditions present in both internal and external environments. Based on this understanding, widely discussed second language theories, including behaviorism, will be treated as explanations of parts of a whole, since each captures a different aspect of SLA. In order to justify this assumption, excerpts from some English language learning histories are provided to exemplify how learners describe their learning processes. The final claim is that SLA should be seen as a chaotic/complex system.
