description: Mirror visual feedback (MVF) is a promising approach to enhance motor performance without training in healthy adults as well as in patients with focal brain lesions. There is preliminary evidence that a functional modulation within and between primary motor cortices as assessed with transcranial magnetic stimulation (TMS) might be one candidate mechanism mediating the observed behavioral effects. Recently, studies using task-based functional magnetic resonance imaging (fMRI) have indicated that MVF-induced functional changes might not be restricted to the primary motor cortex (M1) but also include higher order regions responsible for perceptual-motor coordination and visual attention. However, aside from these instantaneous task-induced brain changes, little is known about learning-related neuroplasticity induced by MVF. Thus, in the present study, we assessed MVF- induced functional network plasticity with resting-state fMRI (rs-fMRI). We performed rs-fMRI of 35 right-handed, healthy adults before and after performing a complex ball-rotation task. The primary outcome measure was the performance improvement of the untrained left hand (LH) before and after right hand (RH) training with MVF (mirror group [MG], n = 17) or without MVF (control group [CG], n = 18). Behaviorally, the MG showed superior performance improvements of the untrained LH. In resting-state functional connectivity (rs-FC), an interaction analysis between groups showed changes in left visual cortex (V1, V2) revealing an increase of centrality in the MG. Within group comparisons showed further functional alterations in bilateral primary sensorimotor cortex (SM1), left V4 and left anterior intraparietal sulcus (aIP) in the MG, only. Importantly, a correlation analysis revealed a linear positive relationship between MVF-induced improvements of the untrained LH and functional alterations in left SM1. Our results suggest that MVF-induced performance improvements are associated with functional learning-related brain plasticity and have identified additional target regions for non-invasive brain stimulation techniques, a finding of potential interest for neurorehabilitation.

Potential anticancer compounds of marine endophytes with inhibitory effects against nasopharyngeal cancer
Creators: name: Kho, Ik Hui
Publisher: name: Swinburne
Year: 2024

description: Nasopharyngeal cancer (NPC) is a disease that is difficult to diagnose and treat due to its complex anatomical location and asymptomatic nature. A rare form of cancer with an unusual geographic distribution, it is found in Southeast Asia and China. The incidence rates are among the highest in Sarawak, an eastern state of Malaysia. In this study, anticancer compounds were induced from co-cultures of marine endophytic fungi with bacteria, significantly enhancing the variety and activity of anticancer compounds. The approach showed great promise in producing compounds selectively inhibiting NPC which could be develop as an alternative treatment to chemotherapy.

description: Objectives The objective of the study was to longitudinally assess the outcomes and correlates of suicidal ideation and behavior (SIB) among heroin users who attended inpatient detoxification and psychosocial rehabilitation. SIB was assessed in 300 heroin users upon entry into inpatient detoxification (baseline) as well as 3-months (t1) (n = 252; 84%) and 9-months (t2) (n = 225; 75%) post treatment. Multivariable logistic regression was used to determine the demographic, clinical and treatment related factors that increased the risk for a high SIB score. Results From baseline to t1 there was a significant decrease in the proportion of those who endorsed SIB (68.7 vs. 38.9%, p < 0.0001). There was an increase in the proportion of those who endorsed SIB from t1 to t2 (38,9 vs. 47.1%, p = 0.047). There was a significant increase in the proportion of those reporting suicide likely in the near future from baseline to t1 (8.7 vs. 16.3%: p < 0.0049) and this was repeated from t1 to t2 (22.7%) (t1 vs. t2: p = 0.031). After controlling for all other variables, a comorbid mental illness (MI) at baseline was a significant independent risk factor for a high SIB score at t1(RR 1.63; 95% CL 1.30–2.03) (p < 0.0001) and a comorbid MI at t1 increased the risk for a high SIB score at t2 (RR 2.73; 95% CL 1.78–4.19) (p < 0.0001). A poorer general health score and poorer social functioning score at baseline were associated with a high SIB score at baseline (RR 1.02; 95% CL 1.01–1.04) (p = 0.001) and t2, respectively (RR 1.07; 95% CL 1.04–1.11) (p < 0.0001). Conclusions Among heroin users, a comorbid mental illness, poorer physical health and poorer social functioning are important factors to consider in suicide risk assessment. Although there were decreases in overall SIB 3 months after detoxification, this trend was not sustained at 9-month follow-up. After detoxification there were significant increases in the proportion of those reporting a likelihood of suicide in the following 3 months. The results suggests that the treatment exposure did not adequately mitigate suicide risk. There is a need for review of the treatment as well as targeted screening and management of SIB in heroin users attending treatment services.

description: The purpose of this laboratory investigation was to study the effect of soil macropores (large non-capillary pores) on infiltration and percolation. This was done by measuring runoff, infiltration and tile flow rates for different macropore populations. The increase in percolation occurring as a result of increased number of macropores is associated with an increased bypass of the soil matrix by percolating water. The basic infiltration capacity increased with increasing number of macropores. This observation was used to develop the concept of macropore index (M-index). In situations where soil M-index changes seasonally, it becomes difficult for appropriate equation parameters to be determined accurately. To enable Horton equation to calculate infiltration in macroporous conditions, an improved form has been suggested. The influence of increasing the population of macropores on surface runoff and tile flow has been investigated. Results indicate that hydrologic models should consider the influence of macropores where populations are likely to change significantly over time. (Abstract shortened by UMI.)

description: Background: Nitrilases are nitrile-converting enzymes commonly found within the plant kingdom that play diverse roles in nitrile detoxification, nitrogen recycling, and phytohormone biosynthesis. Although nitrilases are present in all higher plants, little is known about their function in trees. Upon herbivory, poplars produce considerable amounts of toxic nitriles such as benzyl cyanide, 2-methylbutyronitrile, and 3-methylbutyronitrile. In addition, as byproduct of the ethylene biosynthetic pathway upregulated in many plant species after herbivory, toxic β-cyanoalanine may accumulate in damaged poplar leaves. In this work, we studied the nitrilase gene family in Populus trichocarpa and investigated the potential role of the nitrilase PtNIT1 in the catabolism of herbivore-induced nitriles. Results: A BLAST analysis revealed three putative nitrilase genes (PtNIT1, PtNIT2, PtNIT3) in the genome of P. trichocarpa. While PtNIT1 was expressed in poplar leaves and showed increased transcript accumulation after leaf herbivory, PtNIT2 and PtNIT3 appeared not to be expressed in undamaged or herbivore-damaged leaves. Recombinant PtNIT1 produced in Escherichia coli accepted biogenic nitriles such as β-cyanoalanine, benzyl cyanide, and indole-3-acetonitrile as substrates in vitro and converted them into the corresponding acids. In addition to this nitrilase activity, PtNIT1 showed nitrile hydratase activity towards β-cyanoalanine, resulting in the formation of the amino acid asparagine. The kinetic parameters of PtNIT1 suggest that the enzyme utilizes β-cyanoalanine and benzyl cyanide as substrates in vivo. Indeed, β-cyanoalanine and benzyl cyanide were found to accumulate in herbivore-damaged poplar leaves. The upregulation of ethylene biosynthesis genes after leaf herbivory indicates that herbivore-induced β-cyanoalanine accumulation is likely caused by ethylene formation. Conclusions: Our data suggest a role for PtNIT1 in the catabolism of herbivore-induced β-cyanoalanine and benzyl cyanide in poplar leaves.

description: Background Locoregional hyperthermia combined with radiotherapy significantly improves locoregional control and overall survival for cervical tumors compared to radiotherapy alone. In this study biological modelling is applied to quantify the effect of radiosensitization for three cervical cancer patients to evaluate the improvement in equivalent dose for the combination treatment with radiotherapy and hyperthermia. Methods The Linear-Quadratic (LQ) model extended with temperature-dependent LQ-parameters α and β was used to model radiosensitization by hyperthermia and to calculate the conventional radiation dose that is equivalent in biological effect to the combined radiotherapy and hyperthermia treatment. External beam radiotherapy planning was performed based on a prescription dose of 46Gy in 23 fractions of 2Gy. Hyperthermia treatment using the AMC-4 system was simulated based on the actual optimized system settings used during treatment. Results The simulated hyperthermia treatments for the 3 patients yielded a T50 of 40.1 °C, 40.5 °C, 41.1 °C and a T90 of 39.2 °C, 39.7 °C, 40.4 °C, respectively. The combined radiotherapy and hyperthermia treatment resulted in a D95 of 52.5Gy, 55.5Gy, 56.9Gy in the GTV, a dose escalation of 7.3–11.9Gy compared to radiotherapy alone (D95 = 45.0–45.5Gy). Conclusions This study applied biological modelling to evaluate radiosensitization by hyperthermia as a radiation-dose escalation for cervical cancer patients. This model is very useful to compare the effectiveness of different treatment schedules for combined radiotherapy and hyperthermia treatments and to guide the design of clinical studies on dose escalation using hyperthermia in a multi-modality setting.

description: Background: Arthritis in childhood can be associated with muscle weakness around affected joints, low bone mass and low bone strength. Exercise is recognized as an important part of management of children with juvenile idiopathic arthritis (JIA) but the exercise prescription to best promote bone and muscle health is unknown. We therefore aimed to: 1. assess feasibility and safety of a 6-month home- and group-based exercise program for children with JIA; 2. estimate the effect of program participation on bone mass and strength, muscle function and clinical outcomes and 3. determine if any positive changes in bone and muscle outcomes are maintained 6 months later. Methods: We recruited 24 children with JIA who were part of the Linking Exercise, Physical Activity and Pathophysiology in Childhood Arthritis (LEAP) study to participate in a 6-month home-based exercise program involving jumping and handgrip exercises, resistance training and one group exercise session per month. We assessed lumbar spine bone mass (dual energy X-ray absorptiometry), distal tibia and radius bone microarchitecture and strength (high-resolution peripheral quantitative computed tomography), muscle function (jumping mechanography, dynamometry) and clinical outcomes (joint assessment, function, health-related quality of life) at baseline, 6- and 12-months. Adherence was assessed using weekly activity logs. Results: Thirteen children completed the 6-month intervention. Participants reported 9 adverse events and post-exercise pain was rare (0.4%). Fatigue improved, but there were no other sustained improvements in muscle, bone or clinical outcomes. Adherence to the exercise program was low (47%) and decreased over time. Conclusion: Children with JIA safely participated in a home-based exercise program designed to enhance muscle and bone strength. Fatigue improved, which may in turn facilitate physical activity participation. Prescribed exercise posed adherence challenges and efforts are needed to address facilitators and barriers to participation in and adherence to exercise programs among children with JIA. Trial registration: Data of the children with JIA are from the LEAP study (Canadian Institutes of Health Research (CIHR; GRANT# 107535 ). http://www.leapjia.com/

description: This study investigated community structures of prokaryotes and Symbiodinium spp. found within the tissues of common shallow water Acropora corals of Talang-Satang National Park. Genetic analysis reported significant differences in the microbial diversity of corals collected during Southwest monsoon and Northeast monsoon; disregard corals health conditions. DNA analysis also detected significant changes in microbial communities within transplanted Acropora corals after the attempt to restore partially bleached corals had failed; leading to further tissue losses. Nevertheless, this study has enriched our current knowledge related to microbial diversity found in common Acropora coral that are useful for future coral preservation purposes.

Der Bericht hat auf der Grundlage der Entscheidung der Kommission vom 22.03.2005 zur Festlegung der Tabellenformate zu erfolgen (2005/270/EG). Die Studie bestimmt die in Deutschland in Verkehr gebrachte Menge an Verpackungen (Verpackungsverbrauch) für die Materialgruppen Glas, Kunststoff, Papier, Aluminium, Weißblech, Verbunde, Sonstiger Stahl, Holz und Sonstige Packstoffe. Zur Verbrauchsberechnung wurden neben der in Deutschland eingesetzten Menge von Verpackungen auch die gefüllten Exporte und die gefüllten Importe ermittelt. Aus der in Verkehr gebrachten Menge von Verpackungen wurde die Menge der in Deutschland abfallrelevanten Verpackungsabfälle berechnet, da z.B. Mehrweg- und langlebige Verpackungen erst in Folgeperioden entsorgt werden. Zur Bestimmung der Verwertungsmengen und Verwertungswege wurden die vorliegenden Daten von Verbänden, der Entsorgungswirtschaft und der Umweltstatistik systematisch zusammengetragen und dokumentiert. Im Ergebnis wurden im Jahr 2016 18,16 Mio. t Verpackungen verbraucht und fielen als Abfall an. Insgesamt wurden 17,61 Mio. t Verpackungsabfall verwertet, davon 12,84 Mio. t stofflich und 4,77 Mio. t energetisch. Zusätzlich wurden 2,06 Mio. t aus dem Ausland importierte Verpackungsabfälle in Deutschland verwertet.

description: With the growing ubiquity of educational technology, there has been an increased need for specialised practitioners to advise on and support technology enhanced learning within Higher Education. Academic developers, instructional designers and educational technologists are all examples of these skilled individuals typically working in ‘third space’ that c rosses complex boundaries - between the pedagogical and technological, and the academic and professional. However, role titles and descriptions of duties are often unclear at best, with a lack of consistent terminology used across institutions and in the literature. This can lead to confusion and tensions when working with multiple institutional stakeholders who are uncertain about the abilities and knowledge of people in these roles; potentially exacerbating ‘the academic/professional divide’ in Higher Edu cation and weakening the collaborative relationship between TEL workers and academics. This paper presents a synthesis of key literature related to contemporary TEL advisor and support roles in Higher Education alongside a preliminary analysis of 37 recent position descriptions of these roles. The application of social practice theory as our conceptual framework enables us to further explore the significance of practices in defining and differentiating these roles. This paper offers a step forward to the ways in which clarity and consistency of these roles might be sought. Future implications of this study are included for further consideration.

Der jährliche Zuwachs in der Population wird durch eine glockenähnliche Kurve abgebildet. Beide Funktionen sind auch charakteristisch für wirtschaftliche Entwicklungen, wie Umsatz oder geförderte Ausbauaktivitäten. Die Zahl von Klostergründungen der Zisterzienser oder die Zahl von Renaissancekünstlern in bestimmten Zeitabschnitten folgen weitgehend einer glockenförmigen Kurve.

description: Background The effects of target temperature management (TTM) on the heart aren’t thoroughly studied yet. Several studies showed the prolongation of various ECG parameters including Tpeak-Tend-time under TTM. Our study’s goal is to evaluate the acute and long-term outcome of these prolongations. Methods In this study we included patients with successful resuscitation after cardiac arrest who were admitted to the Charité Virchow Klinikum Berlin or the Heart and Vascular Centre of the Ruhr University Bochum between February 2006 and July 2013 (Berlin) or May 2014 to November 2015 (Bochum). For analysis, one ECG during TTM was recorded after reaching the target temperature (33–34 °C) or in the first 6 h of TTM. If possible, another ECG was taken after TTM. The patients were being followed until February 2016. Primary endpoint was ventricular arrhythmia during TTM, secondary endpoints were death and hospitalization due to cardiovascular diseases during follow-up. Results One hundred fifty-eight patients were successfully resuscitated in the study period of which 95 patients had usable data (e.g. ECGs without artifacts). During TTM significant changes for different parameters of ventricular de- and repolarization were noted: QRS (103.2 ± 23.7 vs. 95.3 ± 18.1; p = 0.003),QT (405.8 ± 76.4 vs. 373.8 ± 75.0; p = 0.01), QTc (474.9 ± 59.7 vs. 431.0 ± 56.8; p < 0.001), JT (302.8 ± 69.4 vs. 278.5 ± 75.2; p = 0.043), JTc (354.3 ± 60.2 vs. 318.7 ± 59.1; p = 0.001). 13.7% of the patients had ventricular arrhythmias during TTM, however these patients showed no difference regarding their ECG parameters in comparison to those were no ventricular arrhythmias occurred. We were able to follow 69 Patients over an average period of 35 ± 31 months. The 14 (21.5%) patients who died during the follow-up had significant prolongations of the TpTe-time in the ECGs without TTM (103.9 ± 47.2 vs. 75.8 ± 28.6; p = 0.023). Conclusion Our results show a significant prolongation of ventricular repolarization during TH. However, there was no significant difference between the ECG parameters of those who developed a ventricular arrhythmia and those who did not. The temporary prolongation of the repolarization during TTM seems to be less important for the prognosis of the patient. Whereas the prolongation of the repolarization in the basal ECG is associated with a higher mortality in our study.

description: Background Carotid artery stenosis can impair cerebral hemodynamics especially within watershed areas (WSAs) between vascular territories. WSAs can shift because of collateral flow, which may be an indicator for increased hemodynamic implications and hence higher risk for ischemic stroke. However, whether revascularization treatment can reverse the spatial displacement of individual WSAs (iWSAs) and impaired hemodynamics remains unknown. Hypothesis That iWSAs spatially normalize because of hemodynamic improvement resulting from revascularization treatment. Study Type Prospective. Population Sixteen patients with unilateral, high‐grade carotid artery stenosis confirmed by duplex ultrasonography and 17 healthy controls. Field strength/Sequences A 3 T‐magnetization‐prepared rapid acquisition gradient echo (MPRAGE), gradient‐echo echo planar dynamic susceptibility contrast (DSC), and fluid‐attenuated inversion recovery (FLAIR) sequences. Additionally, contrast‐enhanced 3D gradient echo magnetic resonance angiography (MRA) and diffusion‐tensor imaging (DTI) spin‐echo echo planar imaging were performed. Assessment iWSAs were delineated by a recently proposed procedure based on time‐to‐peak maps from DSC perfusion MRI, which were also used to evaluate perfusion delay. We spatially compared iWSAs and perfusion delay before and after treatment (endarterectomy or stenting). Additionally, the Circle of Willis collateralization status was evaluated, and basic cognitive testing was conducted. Statistical Tests Statistical tests included two‐sample t‐tests and Chi‐squared tests. A P value < 0.05 was considered to be statistically significant. Results After revascularization, patients showed a significant spatial shift of iWSAs and significantly reduced perfusion delay ipsilateral to the stenosis. Spatial shift of iWSA (P = 0.007) and cognitive improvement (P = 0.013) were more pronounced in patients with poor pre‐existing collateralization. Controls demonstrated stable spatial extent of iWSAs (P = 0.437) and symmetric perfusion delays between hemispheres over time (P = 0.773). Data Conclusion These results demonstrate the normalization of iWSA and impaired hemodynamics after revascularization in patients with high‐grade carotid artery stenosis.

description: Ce projet présente une analyse des représentations de groupes ethniques dans les manuels scolaires d'études sociales destinés aux élèves des écoles de langue française de l'Ontario de cinquième et sixième année. L'analyse critique du discours, qui vise à relever les relations entre le texte, le langage, les groupes et les pratiques sociales, nous révèle comment sont représentés les groupes ethniques. Inspiré d'English Learning Area, nous avons retenu quatre catégories pour tenter de mettre en lumière les attitudes, les valeurs et les croyances cachées dans un discours : la structure, la construction des personnages, les omissions et les pouvoirs. Notre recherche démontre qu'il y a présence de relations de pouvoir dans le contenu latent des manuels analysés. Cette conclusion nous amène à formuler des suggestions. Ainsi, cette recherche propose des pistes de solution qui permettraient une représentation plus juste des groupes ethniques dans le matériel scolaire.

description: Glioblastoma (GBM) is one of the most aggressive types of cancer with limited therapeutic options and unfavorable prognosis. Stemness and non-classical epithelial-to-mesenchymal transition (ncEMT) features underlie the switch from normal to neoplastic states as well as resistance of tumor clones to current therapies. Therefore, identification of ligand/receptor systems maintaining this privileged state is needed to devise efficient cancer therapies. In this study, we show that the expression of CD95 associates with stemness and EMT features in GBM tumors and cells and serves as a prognostic biomarker. CD95 expression increases in tumors and with tumor relapse as compared with non- tumor tissue. Recruitment of the activating PI3K subunit, p85, to CD95 death domain is required for maintenance of EMT-related transcripts. A combination of the current GBM therapy, temozolomide, with a CD95 inhibitor dramatically abrogates tumor sphere formation. This study molecularly dissects the role of CD95 in GBM cells and contributes the rational for CD95 inhibition as a GBM therapy.

description: With new generations of high-resolution imaging radars the orientation of vehicles can be estimated without temporal filtering. This enables time critical systems to respond even faster. Based on a large data set this paper compares three generic algorithms for the orientation estimation of a vehicle. An experimental MIMO imaging radar is used to highlight the requirements of a robust algorithm. The well-known orientated bounding box and the so-called L-fit are adapted for radar measurements and compared to a brute-force approach. A quality function selects the best fitted model and is a key factor to minimize alignment errors. Moreover, the reliability of the estimation is evaluated with respect to the aspect angle, the distance to the target, and the number of sensors. An approach to estimate the reliability of the current orientation estimation is introduced. It is shown that the root mean square error of the orientation estimation is 9.77° and 38% smaller compared to the common algorithm. In 50% of the evaluated measurements the orientation estimation error is smaller than 3.73°.
Pinpointing the Origins of Fast Radios Bursts
Creators: name: Day, Cherie
Publisher: name: Swinburne
Year: 2024

description: One of the great mysteries of modern astrophysics, fast radio bursts (FRBs) are short-duration, energetic bursts of radio-wavelength emission predominantly originating outside the Galaxy. This thesis enriches our current understanding of FRBs, investigating the temporal and spectral properties of the largest (to date) sample of localised FRBs, shedding light on the environments through which they traverse and furthering our understanding of the universe. It also presents the development of receiver technology engineered to facilitate localisation of FRBs --thereby associating individual signals to their host galaxies --and investigates the accuracy of positions attainable with the Australian Square Kilometre Array Pathfinder.
Geology, structure and gold mineralization within the Porcupine-Destor Deformation Zone, Harker-Holloway gold camp, southwestern Abitibi Greenstone Belt, Canada

description: The Harker-Holloway gold camp is located along the Porcupine-Destor Deformation Zone in the northern portions of Harker and Holloway Townships, Ontario. The gold camp is host to two operating gold mines, the Holloway and Holt-McDermott mines as well as several minor gold showings. The Holloway and Holt-McDermott deposits are located entirely within splays of the Porcupine-Destor Deformation Zones within meta-volcanic rocks of the Kidd-Munro and Kinojevis lithotectonic assemblages, respectively, and are separated by a narrow band of Timiskaming meta-sedimentary rocks. The rocks of the area form a steeply south dipping package within which rocks have been deformed associated with development of the Porcupine-Destor Deformation Zone. Within the Holloway mine, a polylithic breccia folded into the volcanic stratigraphy was dated at 2686.6 +/- 1.8 Ma. Meta-volcanic rocks which host the two deposits belong to a tholeiitic suite of rocks and can be separated into four distinct groups based on lithogeochemistry. Tholeiites all have flat lying REE profiles and can be grouped into Types I, II and III based on increasing normalized REE values and are interpreted to represent a fractional crystallization trend from a tholeiitic source magma. An additional trachytic meta-volcanic unit was identified in the Holt-McDermott mine and is characterized by an enriched LREE profile and is interpreted to have formed via fractional crystallization from tholeiitic magma. Several episodes of gold mineralization have been identified in the area. The first and most economically important gold mineralizing event (Au1) is associated with albite alteration (Ab) and pyrite mineralization (Py1). Primary gold mineralization (Au1) predates D1 deformation, and is confined to specific stratigraphic units bounded by zones of intense S1 foliation development. A second, volumetrically less important, gold mineralization (Au2) is located within haloes of subhorizontal quartz-carbonate veins which cross cut the S1 foliation. Secondary mineralization is associated with a sericite+carbonate alteration (Sr) and a second generation of pyrite mineralization (Py2) and is interpreted to be a remobilization of primary gold mineralization. A third, volumetrically minor, gold mineralization event (Au3) is associated with N to NNE striking quartz veins which cross cut all other structures. (Abstract shortened by UMI.)

description: Previous research has established a role for the norepinephrine/stress system in individual differences in biases to attend to reward or punishment. Outstanding questions concern its role in the flexibility with which such biases can be changed. The goal of this pre-registered study was to examine the role of the norepinephrine (NE)/stress systems in the degree to which biases can be trained along the axis of valence in the direction of reward. Participants genotyped for a common deletion variant of ADRA2b (linked to altered NE availability) experienced an acute stress induction or control procedure. Following stress induction, a “bias-probe” task was presented before and after training. In the bias-probe, participants made forced-choice judgments (happy or angry) on emotional faces with varying degrees of ambiguity. For bias training, participants viewed unambiguously angry faces in a task exploiting visual adaptation effects. Results revealed an overall shift from a slightly positive bias in categorizing faces pre training to a more positive bias after training. Carriers of the deletion variant showed overall a more positive bias than non-carriers. Follow-up analyses showed that pre-training bias was a significant predictor of bias change, with those who showed a more negative bias pre-adaptation changing more in a positive direction. Critically, this effect was observed under control but not under stress conditions. These results suggest that the NE/stress system plays an important role in influencing trait-like biases as well as short-term changes in the tendency to perceive ambiguous stimuli as more rewarding than threatening.
Identification and characterization of a cost-effective combination of systems for Arctic surveillance: The Northern Watch project

description: This thesis discusses a new stream of research and analysis which will form part of the Northern Watch Technology Demonstration project. The objective of the thesis is to develop and illustrate a procedure for identifying and characterizing combinations of sensors and systems that will provide cost-effective options for Arctic maritime surveillance. A ship detection simulation is constructed, the results of which are used to produce a set of ranked options for combinations of sensors used to conduct maritime surveillance at a strategic choke point located at the Barrow Strait, in Canada's Northwest Passage. The overall objective of the surveillance is to improve on the detection, classification, and identification of maritime vessels. The modeled performance and effectiveness of each sensor is evaluated in relation to the multiple objectives using the Analytical Hierarchy Process (AHP) to rank alternative sensor effectiveness and performance. The results indicate that the most cost-effective solution is to install an Automatic Identification System (AIS) sensor at the Northern Watch station. However, due to practical concerns, alternatives to this approach are presented and discussed.
