Feature extraction for exploring infarcted regions in perfusion CT images of the brain

In Norway, over 15 000 people suffer from acute cerebral stroke annually, it is the leading cause of adult long-term severe disability and a significant reason for admission to nursing homes. In Norway it is a prominent cause of death among adults, being the third leading cause of death. On a worldwide basis, 6.7 million deaths were due to stroke in 2012, most of them in lowand medium-income countries. At Stavanger University Hospital (SUS), patients are routinely investigated using perfusion computed tomography (PCT) in the acute setting. The images acquired are used to calculate parametric color-coded maps describing the blood perfusion in the brain. These maps are interpreted, and thereby aid in deciding whether a patient need immediate thrombolytic treatment. This interpretation is critical in tailoring treatment to each patient, and thus saving lives and reducing the possibility of severe disability. The parametric maps are distant with regards to a certain diagnostic accuracy, and further refinement of the techniques and methods in use are desired. More accurate evaluation of PCT can lead to better guidance of whom to treat with thrombolyticand interventional therapy, with the goal of better treatment for the patients. The primary objective of this thesis is to arrange and process the available data material. Additionally, exploration of multiple features that describe a healthy hemisphere of the brain compared to a hemisphere with impaired perfusion is conducted. Results show that textural features extracted by Local Binary Pattern (LBP) and wavelets can demonstrate a definite difference in the chi-squared distance measured in a healthy hemisphere compared to a hemisphere with impaired perfusion. Over different time-series, the distinctiveness of the features varied, by comparing them to the Time-Density Curves (TDC) for the actual patient, the better features seemed to be extracted from more complex wavelets like Daubechies-4 and Coiflet-4. Textural features extracted from the Gray Level Co-occurrence Matrices (GLCM) proved challenging to interpret, but by combining them with textural features extracted by Coifletwavelets, they were able to distinguish the two hemispheres for each patient.
Artificial neural network applied to estimate the power output of bipv systems

This paper presents an artificial neural network (ANN) model to estimate the power generated by integrated photovoltaic systems in buildings BIPVS. The model has as primordial variables, the solar radiation and the ambient temperature of the site of installation of the photovoltaic generator and integrates secondary variables such as the zenith solar angle and the azimuth solar angle. The artificial neural network consists of three layers of operation that allows to adapt to the behavior of the environmental and electrical variables of the photovoltaic generator to create output variables of electrical power through daily profiles. The neural network was implemented in the software MatlbabTM and it was validated using the actual data of monitoring of a 6 kW BIPV system installed at Universidad de Bogotá Jorge Tadeo Lozano, in Bogotá, Colombia. The results indicate a correlation coefficient of 98% on the output power of the BIPV system between the artificial neural network and the performance data of the solar photovoltaic plant. These results show the reliability of the model for PV systems operating in different climatic conditions and different generation capacities.
The Effect of Fabric Type and Laundering Conditions on the Detection of Semen Stains

There has been little research into the effect of fabric type and different laundering conditions on the ability to detect semen stains on washed fabrics. This study aimed to investigate three potential factors affecting semen identification on laundered clothing: fabric type, water temperature during washing, and whether the stain was dry at the time of washing. Following laundering, semen stains on four fabric types (cotton, polyester, denim, and wool) were examined and tested with three common methods used to detect semen; screening with an alternate light source, acid phosphatase press test, and histological staining of spermatazoa. It was determined that semen was difficult to detect if it was still wet when the semen-stained article was washed. There did not appear to be any difference based on the temperature of the wash cycle. It was also determined that synthetic fabrics such as polyester may not effectively retain the components of semen during laundering, making detection more difficult.
Near-field surface plasmon effects on Au-double-slit diffraction for polychromatic light

The surface plasmon effects on near-field diffraction for polychromatic light are studied. An Au-double-slit is used as the model and Fresnel integral is employed to perform the theoretic analysis. The results are illustrated with numerical examples and they show that, compared with the normal double-slit, the plasmon effect changes the spectral shift from redshift to blueshift and also enhances the intensity peak. This effect can be used in optical data transmission or specific spectral selectors.
Measuring English Teachers’ Use of Technology: Multiple Measures and Their Importance

Governments and administration of schools have been interested in making huge investment in integration of computer technology since 1990. Computer technology have brought many advantages and benefits for learning environment and educational system, however, many researchers have provided evidence that computer technology is affecting the lives of students and teachers. Hence, it is necessary to evaluate the impact of technology on learning so that investments could be steered in the most effective ways. This study aims to explore teachers’ technology use in which measurement of technology use is emphasized considering the pertinence of research method to conduct a study. Quantitative research methodology has adopted in which primary data was collected from teachers of K – 12 schools. Comparison has made between single composite and multiple measure approach to study the impact of computer in schools. Results provide a coherent view and insight into the methods of measuring teachers’ technology use and improved strategies.
Latest results of the LHCf experiment at LHC

In 2016 the LHCf experiment has fulfilled its original goal of measuring the spectra of the neutral particles produced in the very forward direction at LHC at the highest energy ever available. The main purpose of these measurements is indeed to provide the Cosmic Ray and High Energy Physics communities with a missing unique set of information for the improvement of the hadronic interaction models used to simulate air showers development produced in the interaction of primary High Energy Cosmic Rays (HECR) with the Earth atmosphere. The last data sets collected by the LHCf experiment have been obtained during p+p collisions, at an energy of 13 TeV in the CM frame, and p+Pb collision, at an energy of the colliding nucleon pair of 5.2 TeV and 8.1 TeV in the CM frame. A review of the main results of LHCf and of the recent and on-going activities are presented.

SECURE SCHEMES FOR SECRET SHARING AND KEY DISTRIBUTION USING PELL'S EQUATION

A key distribution scheme for dynamic conferences is a method by which initially an trusted server distributes private individual pieces of in- formation to a set of users. Later each member of any group of users of given size can compute a common secure group key. In this setting any group of t users can compute a common key by each user computing using only his pri- vate initial piece of information and the identities of the other t − 1 users in the group. Keys are secure against coalition of to k users, that is, even if k users pool together their pieces they cannot compute anything about a key of any t-size conference comprised of other users. In this paper, we introduce an algorithm for such perfectly secure scheme by using Pell's equation.
roposing an interdisciplinary and cross-scale framework for global change and ood security researches

Food security is greatly affected by the consequences of global change, especially its impact on agriculture. Currently, global change and food system interaction is a hot issue across the scientific community. Scientists have tried to explain this interaction from different perspectives, and the issues related to this interaction can be classified as (1) crop yield and productivity in response to global change; (2) crop distribution and allocation in relation with global change; (3) general impacts on food security. However, most of the existing studies lack consistency and continuity. As food systems exist at the intersection of the coupled human and natural system, the interdisciplinary context of global change and food security requires an integrated and collaborative framework for better describing their importance and complexity. To do so, we decompose global change/food security studies into different levels in accordance with the previous mentioned issues, field, regional, and global, and categorize them into the life sciences, earth and environmental sciences, and social and sustainability sciences, respectively (yet not necessarily one to one correspondence). At the field level, long-term observations and controlled experiments in situ are important for exploring the mechanism of how global change will affect crop growth, and for considering possible adaptation methods that may maximize crop productivity. At the regional level, priority should be given to monitoring and simulating crop production (animal production and fishery are not included here) within large areas (a region or a continent). At the global level, food security studies should be based on scenario assessments to prioritize human adaptations under the changed environment, using integrated socioeconomic–biogeophysical measures. © 2012 Elsevier B.V.

ECOTOXICOLOGICAL BIOASSAYS OF THE EARTHWORMS ALLOLOBOPHORA CALIGINOSA SAVIGNY AND PHERETIMA HAWAYANA ROSA TREATED WITH ARSENATE

Little research has been carried out on the effect of arsenate on earthworms. Ecotoxicological laboratory tests are fundamental tools for assessing the toxicity of arsenate to soil organisms. In this study, the impact of arsenate on the survival, reproduction and behaviour of the endogenic earthworms Allolobophora caliginosa and the anecic earthworms Pheretima hawayana has been quantified. The 96-h LC 50 of arsenate was estimated as 233.43 mg arsenate Kg-1 soil. d.w. for P. hawayana which is significantly higher than that of A. caliginosa 147.24±27.16 mg arsenate kg-1 soil d.w. The number of juveniles of P. hawayana was significantly higher than that of A. caliginosa at the arsenate concentrations 180, 240 and 400 mg kg-1 soil dry weight. With the exception of the control (6.5 mg arsenate kg-1 soil.d.w.), P. hawayana showed an avoidance behaviour for soils treated with all tested concentrations. A. caliginosa preferred soils treated with 6.5, 60, 110, 180 mg arsenate kg-1 soil d.w. , while the avoidance behaviour has been recorded only at 240 and 400 mg arsenate kg-1 soil. d.w. This means that A. caliginosa individuals feed less when exposed to arsenate. On the contrary, the P. hawayana worms could be escaped into their deep vertical burrows when exposed to arsenate.
Evolutionary branching/speciation: contrasting results from systems with explicit or emergent carrying capacities

In this paper, we use the theory of adaptive dynamics to highlight the differences in evolutionary behaviour when contrasting formulations of the carrying capacity are used. We use two predator–prey systems, one with a fixed carrying capacity and one in which the carrying capacity is an emergent property compounded of an intrinsic growth rate and a susceptibility to crowding. We consider prey evolution in both systems and link the evolving parameters by a trade-off which requires that prey with higher per capita growth experience a greater risk of predation. We find that the two approaches for representing the carrying capacity can lead to markedly different evolutionary behaviour. In particular, the possibility of exhibiting evolutionary branching requires an emergent carrying capacity. This is significant, since evolutionary branching is regarded as a possible mechanism by which sympatric speciation may occur.
New perspectives in hemoglobin adducts analysis: selective digestion with Calpain I

Background: hemoglobin adducts are considered suitable biomarkers to evaluate human exposure to electrophile agents. One of the procedures used for the molecular dosimetry of hemoglobin adducts is the enzymatic digestion of the protein and the subsequent quantification of modified peptides by mass spectrometry. The aim of the study is to evaluate the ability of Calpain to discriminate between normal and alkylated globin chains. Methods: digestions of pure hemoglobin sample and of an alkylated one with Calpain I at 200:1 and 25:1 weight ratios, for 1, 5 and 18 hrs were carried out. Only the standard deviations (SD) of the ratios between alkylated globins with respect to the unmodified ones (αECH/α and bECH/b) were estimated because the aim of the study is to assess the ability of Calpain I to selectively digest the samples and, above all, to find the optimal digestion conditions and characterize obtained peptides. Results: by using a 200:1 weight ratio only peptides α(1-137), α(1-138) and b(1-142) were produced, pointing out that the first proteolytic sites are located at the C-terminus ends of both αand b-chains. The identification of peptides obtained from the 25:1 digestions allowed the determination of internal secondary proteolytic sites, not reported in literature. In both cases, a non-negligible proteolysis was observed only when a reaction time of
The Effects of Human Capital on the Total Quality Management: High Technology Sectors

The firms should place quality at the top of its strategic priority if they want to survey and attain competitive advantage. Among the most effective quality techniques that have been verified by several organizations from several sectors and countries, there is the Total Quality Management (TQM) technique. Besides, literature indicates that human capital is considered as the substantial source of growth and organizational sustainability of companies. In this sense, this study seeks to investigate the effect of human capital on the achievement of TQM. A questionnaire survey was developed and distributed to a sample of 146 employees working in companies installed in Tabuk region in Saudi Arabia. SPSS software program was used for statistical data analysis. Results showtwo critical success factors of TQM which are the cooperative and supportive leadership, and the employees' job satisfaction.
The ISC-GEM Earthquake Catalogue (1904–2014): status after the Extension Project

Abstract. We outline the work done to extend and improve the ISC-GEM Global Instrumental Earthquake Catalogue, a dataset which was first released in 2013 (Storchak et al., 2013, 2015). In its first version (V1) the catalogue included global earthquakes selected according to time-dependent cut-off magnitudes: 7.5 and above between 1900 and 1918 (plus significant continental earthquakes 6.5 and above); 6.25 between 1918 and 1959; 5.5 between 1960 and 2009. Such selection criteria were dictated by time and resource limitations. With the Extension Project we added both pre-1960 events below the original cut-off magnitudes (if enough station data were available to perform relocation and magnitude recomputation) and added events with magnitude 5.5 and above from 2010 to 2014. The project ran over a 4-year period during which a new version of the ISC-GEM Catalogue was released each year via the ISC website (http://http://www.isc.ac.uk/iscgem/, last access: 10 October 2018). For each year, not only have we added new events to the catalogue for a given time range but also revised events already in V1 if additional data became available or location and/or magnitude reassessments were required. Here we recall the general background behind the production of the ISC-GEM Catalogue and describe the features of the different periods in which the catalogue has been extended. Compared to the 2013 release, we eliminated earthquakes during the first 4 years (1900–1903) of the catalogue (due to lack of reliable station data), added approximately 12 000 and 2500 earthquakes before 1960 and between 2010 and 2014, respectively, and improved the solution for approximately 2000 earthquakes already listed in previous versions. We expect the ISC-GEM Catalogue to continue to be one of the most useful datasets for studies of the Earth's global seismicity and an important benchmark for seismic hazard analyses, and, ultimately, an asset for the seismological community as well as other geoscience fields, education and outreach activities.

Layer by Layer Composite Membranes of Alginate-Chitosan Crosslinked by Glutaraldehyde in Pervaporation Dehydration of Ethanol

Hydrophilicity of membrane causing only water can pass through membrane. Pervaporation process using organophilic membrane has been offered as alternative for ethanol dehydration. This paper investigate pervaporation based biopolymer composite membrane from alginate-chitosan using layer by layer method prepared by glutaraldehyde as crosslinking agent and polyethersulfone (PES) as supported membrane. Characterization of crosslinked of composite membrane by FTIR helped in identification of sites for interaction between layers of membrane and support layer (PES). The SEM showed a multilayer structure and a distinct interface between the chitosan layer, the sodium alginate layer and the support layer. The coating sequence of membranes had an obvious influence on the pervaporation dehydration performance of membranes. For the dehydration of 95 wt% ethanol-water mixtures, a good performance of PES-chitosan-alginate-chitosan (PES/Chi/Alg/Chi) composite membrane was found in the pervaporation dehydration of ethanol.

Estimation of Global Solar Radiation using Pyranometer and NILU-UV Irradiance Meter at Pokhara Valley in Nepal

The global solar radiation (GSR) and cloud transmittance factor (cf) are measured at the horizontal surface since 2009 using calibrated CMP6 Pyranometer and NILUUV Irradiance Meter at Pokhara (28.22°N, 83.32°E) which is about 800m from the sea level lying just 20km south of the Himalayas. This paper explains the daily, monthly and seasonal variation of global solar radiation and also compared with temperature and rainfall to global solar radiation. The annual average daily global solar radiation is about 4.81 kWh/m 2 /day which is sufficient to promote solar active and passive solar energy technology at sub-Himalaya terrain Pokhara and other similar geographical locations. The correlation coefficient 0.70 is found in between clearness index (K) and cloud transmittance factor (cf). This novel result can be used for location of similar meteorological and geographical characteristics at which solar data are not available.

Maxillary restoration with complete maxillary prosthesis supported by implants with immediate loading: clinical retrospective study of 48 cases

Introduction: In recent years, the immediate loading procedure for the rehabilitation of edentulous jaws has gained popularity among patients and practitioners. The purpose of this study was to evaluate implant and prosthetic success rates for the rehabilitation of edentulous maxillae using tilted distal implants and immediate loading of prostheses, after 2 years. Material and method: Patients included in the study received a complete prosthesis of the upper arch, attached to 4, 5 or 6 implants. The provisional prosthesis was fixed the same day the implants were placed. After a period of osseointegration, the provisional prosthesis was replaced by a definitive prosthesis with a titanium framework made using computer-aided design/computer-assisted manufacturing (CAD/CAM) technology. Judgment criteria were the implant success rate, the provisional prosthesis success rate, and the definitive prosthetic success rate. Results: Two hundred and forty-two implants were placed in 48 patients. Five implants were lost, resulting in an implant survival at 2 years of 97.9%. Two provisional fixed prosthesis had to be temporarily replaced by a removable solution, resulting in a provisional prosthesis success rate of 95.8%. The definitive prosthesis success rate was 100%. Discussion: Use of a provisional prosthesis during the osseointegration period is essential, both for the preparation of the final prosthesis as well as for proper management of potential implant failures. Implant failures are more easily managed if at least five implants were originally placed.
Academic and Linguistic Gains during a Semester-Long Study Abroad: A Cohort Case Study.

The present case study investigated university students’ academic and linguistic gains during a semester-long exchange program abroad. Thirty three third-year English majors from a Chinese university answered a battery of questionnaires and 13 of them participated in semi-structured interviews both prior to and after the program. Analyses of the data showed that the participants gained greatly from the exchange program both academically and linguistically. Based on the findings, some implications about exchange programs are discussed.
