description: For over 25 years, common belief has been widely viewed as necessary for joint behavior. But this is not quite correct. We show by example that what can naturally be thought of as joint behavior can occur without common belief. We then present two variants of common belief that can lead to joint behavior, even without standard common belief ever being achieved, and show that one of them, action-stamped common belief, is in a sense necessary and sufficient for joint behavior. These observations are significant because, as is well known, common belief is quite difficult to achieve in practice, whereas these variants are more easily achievable.

description: Single layers of transition metal dichalcogenides, such as WSe$_2$ have gathered increasing attention due to their intense electron-hole interactions, being considered promising candidates for developing novel optical applications. Within the few-layer regime, these systems become highly sensitive to the surrounding environment, enabling the possibility of using a proper substrate to tune desired aspects of these atomically-thin semiconductors. In this scenario, the dielectric environment provided by the substrates exerts significant influence on electronic and optical properties of these layered materials, affecting the electronic band-gap and the exciton binding energy. However, the corresponding effect on the luminescence of transition metal dichalcogenides is still under discussion. To elucidate these impacts, we used a broad set of materials as substrates for single-layers of WSe$_2$, enabling the observation of these effects over a wide range of electrical permittivities. Our results demonstrate that an increasing permittivity induces a systematic red-shift of the optical band-gap of WSe$_2$, intrinsically related to a considerable reduction of the luminescence intensity. Moreover, we annealed the samples to ensure a tight coupling between WSe$_2$and its substrates, reducing the effect of undesired adsorbates trapped in the interface. Ultimately, our findings reveal how critical the annealing temperature can be, indicating that above a certain threshold, the heating treatment can induce adverse impacts on the luminescence. Furthermore, our conclusions highlight the influence the dielectric properties of the substrate have on the luminescence of WSe$_2$, showing that a low electrical permittivity favours preserving the native properties of the adjacent monolayer

description: Abstract: The study was initiated to assess the level of soil acidity and lime requirement of four types of land uses (forest lands, grazing lands, cultivated lands, and Eucalyptus tree plantation) and in replications from 0-20 cm soil depth. Lime requirement was evaluated by exchangeable acidity and buffer solution methods. The data were analyzed by SAS software, version 9.1. The study revealed that soils of cultivated and Eucalyptus lands were very strongly acidic with mean of pH 4.8 and 5.0, whereas soils of grazing lands were strongly acidic with pH 5.5 and forest lands were moderately acidic with pH 5.7and 5.6 in both kebeles, respectively. Meaningfully higher pH, OM, TN, CEC, exchangeable Ca2+, and Mg2+ were noted under forest lands as compared to the remaining land uses. However, meaningfully lower exchangeable acidity (EA) (1.06) and percentage acid saturation (PAS) (5.18) were obtained in the forest lands than in the other land uses. Significantly higher available P (2.54) was noted in the grazing land, followed by natural forest (1.77) land for Berchernamocheya kebele, and higher available P was recorded under forest (2.50), followed by grazing land (2.37) for Badnayegor kebele. Significantly higher exchangeable K+ (1.29) and Na+ (0.63) were observed in grazing land for Badnayegor and Berchernamocheya Kebeles, respectively. The results of the lime requirement revealed that using the SMP buffer solution method recorded 4.1-11.3 t/ha while using the exchangeable acidity method recorded 1.3-6.7 t/ha across the land uses for both kebeles. Based on lime requirement determination methods, the amount of lime required highly varies among the land uses. The investigation showed that soil acidification is a serious problem in the study areas. Thus, integrated land management needs to be practiced to overcome the problem of soil acidification and achieve sustainable agricultural production.

description: The purpose of this study was to assess the practices of performance management system implemented in Oromia International Bank (OIB). The study tried to address the basic questions whether the purposes and concepts of PMS is well defined and communicated to employees, how the alignment is made between organizational goal and with that of the departmental and individual goal, how the planning, execution, assessment and review process was handled, how performance management system is integrated with reward and training and development and what are the challenges in implementing performance management system in OIB is covered in this study. To answer these questions descriptive survey research design has been deployed by using both quantitative and qualitative research approach. The total number of employees at OIB heads office and grade-3 branches is 630 and the sample size based on Robert & Daryle (1970) is 240. For this study simple random sampling and purposive sampling techniques was used by taking 240 employees at all levels, managerial and non-managerial. Data collection instruments used for this study was questionnaires, interviews and document reviews. The data gathered from the questionnaire were compiled by using SPSS software. Descriptive statistics method was used for analyzing data obtained from questionnaire and the results were presented using tables. The data gathered from interview and document analysis were analyzed and organized as summary. In general the finding of the study revealed that the planning stage of performance management system at OIB is not participative one, no self assessment methods for employees, weak link between performance and reward and training and development, lack of regular feedback, limited sources while collecting information during performance assessment are the major findings that need improvement. order to fill the identified gap, recommendations were forwarded to improve manager's commitment, to improve the level of employee's participation in the PMS process, letting employees to assess their own performance using self-appraisal method, gather information about the performance of an employee from different sources , to structure PM as separate division in Oromia International Bank.

description: Recently, differences in Doppler shifts across the base of four close classical T Tauri star jets have been detected with the HST in optical and near-ultraviolet (NUV) emission lines, and these Doppler shifts were interpreted as rotation signatures under the assumption of steady state flow. To support this interpretation, it is necessary that the underlying disks rotate in the same sense. Agreement between disk rotation and jet rotation determined from optical lines has been verified in two cases and rejected in one case. Meanwhile, the NUV lines, which may trace faster and more collimated inner spines of the jet than optical lines, either agree or show no clear indication. We propose to perform this test on the fourth system, Th 28. We present ALMA high angular resolution Band 7 continuum, 12CO(3-2) and 13CO(2-1) observations of the circumstellar disk around the T Tauri star Th 28. We were able to detect, in CO and continuum, clear signatures of a disk in Keplerian rotation around Th28. The 12CO emission is resolved, allowing us to derive estimates of disk position angle and inclination. The large velocity separation of the peaks in 12CO, combined with the resolved extent of the emission, indicate a central stellar mass in the range 1-2 Msun. The rotation sense of the disk is well detected in both 13CO and 12CO emission lines, and this direction is opposite to that implied by the transverse Doppler shifts measured in the optical lines of the jet. The Th 28 system is the second system where counter-rotation between the disk and the optical jet is detected. These findings imply either that optical transverse velocity gradients detected with HST do not trace jet rotation or that modeling the flow with the steady assumption is not valid. In both cases jet rotation studies that rely solely on optical lines are not suitable to derive the launching radius of the jet.

How Central Bank Responds to Macroeconomic Shocks? Specification, Estimation and Analysis of Monetary Policy Reaction Function: The Case of Ethiopia (1991-2005)
Creators: name: Sime, Zerayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: This paper presents a model of monetary policy in Ethiopia after financial liberalization policy adopted. It is designed to identify both the goals and pattern of policy with the two major aims: firstly to know the way how National Bank of Ethiopia systematically responds to macroeconomic shocks and secondly to evaluate the performance monetary policy against its initial objective including assessment of gap analyses in monetary policy frame work. Hence, the model demonstrates that the National Bank of Ethiopia chooses the domestic credit as the most appropriates indicator of monetary policy with the determinants of net foreign assets, consumer price index, fiscal gap, real effective exchange rate and Gross Domestic Products to formulate the reaction function. On top of this the empirical results explain that domestic credit has strong long run & positive relation with net foreign assets & to real Gross Domestic Product. But it has short run relation with consumer price index, real effective exchange rate and real Gross Domestic Product at different lag structure. The NBE followed a combination of both accommodating and stabilization monetary policy. The Coefficients of equilibrating error terms, ECM suggest that the speed of adjustment/ feed back effect towards the long run equilibrium takes many years for full adjustment when there is a shock in the system, indicating the longer lags structure and undeveloped financial sectors resulted in obstacles for the effectiveness of monetary policy. Regarding to the evaluation of monetary policy objectives up on short run dynamics model, Both low inflation rate and reduction of monetization of fiscal deficit can be maintained in the review period while achieving the international reserve target is not fully under the control of NBE. Basically, the attempts of NBE to maintain the growth rate of money supply at the rate of nominal GDP growth has been satisfactorily met in the review period The sterilization coefficient revealed incomplete sterilization activities while the offset coefficient tell us a highest degree of monetary control with low degree of capital mobility. Therefore in general due to the non-existence of a well-developed secondary market, the lack of latitude to engage in discretionary activities, and partial monetization of the economy make the monetary policy implementation ineffective.

description: We reported the location of a lodged bullet inside a human brain from the 2D and 3D images using Computed Tomography (CT). It is based on the scanning of the hard and the soft tissues of the brain as well as a bullet by X-ray photons on the circular 3600 CCD detectors. The absorption on the target brain and the bullet had significant differences in the measured current (mA) and the mapped Hounsfield Unit (HU) as a function of the number of slices. The 2D and the reconstructed 3D images displayed the brain soft tissue, which was dark with low HU compared to the white in the bullet part with a higher HU. The attenuation coefficients of a bullet with Copper (Cu) and the skull of the brain with Calcium (Ca) were higher than that of the brain soft tissues with Hydrogen (H) and Oxygen (O). A typical example is the observation of the image at the center of the slices displayed brighter at 3071 HU. 3D structures of brain images were generated and visualized in different viewing positions. The measured value for a lodged bullet was 11.28 cm away from its entry (Frontal), 7.92 cm from the back, and 6.96 cm deep, down from the upper part of the brain. Based on our analysis, the bullet is located in the left hemisphere, which is part of the hypothalamus and parity.

description: Background: Recent high-precision measurements of alpha-induced reaction data below the Coulomb barrier have pointed out questions of the alpha-particle optical-model potential (OMP) which are yet open within various mass ranges. Purpose: The applicability of a previous optical potential and eventual uncertainties and/or systematic errors of the OMP assessment at low energies can be further considered on this basis. Method: Nuclear model parameters based on the analysis of recent independent data, particularly gamma-ray strength functions, have been involved within statistical model calculation of the (alpha,x) reaction cross sections. Results: The above-mentioned potential provides a consistent description of the recent alpha-induced reaction data with no empirical rescaling factors of the and/or nucleon widths. Conclusions: A suitable assessment of alpha-particle optical potential below the Coulomb barrier should involve the statistical-model parameters beyond this potential on the basis of a former analysis of independent data.

description: We have studied the production and decay of the $f_1(1285)$ into $πa_0(980)$ and $K^* \bar K$ as a function of the mass of the resonance and find a shoulder around 1400 MeV, tied to a triangle singularity, for the $πa_0(980)$ mode, and a peak around 1420 MeV with about 60 MeV width for the $K^* \bar K$ mode. Both these features agree with the experimental information on which the $f_1(1420)$ resonance is based. In addition, we find that if the $f_1(1420)$ is a genuine resonance, coupling mostly to $K^* \bar K$ as seen experimentally, one finds unavoidably about a 20\% fraction for $πa_0(980)$ decay of this resonance, in drastic contradiction with all experiments. Altogether, we conclude that the $f_1(1420)$ is not a genuine resonance, but the manifestation of the $πa_0(980)$ and $K^* \bar K$ decay modes of the $f_1(1285)$ at higher energies than the nominal one.

description: Attaining milli-Kelvin temperatures is often a prerequisite for the study of novel quantum phenomena and the operation of quantum devices. Adiabatic demagnetization refrigeration (ADR) is an effective, easy and sustainable alternative to evaporation or dilution cooling with the rare and super-expensive $^3$He. Paramagnetic salts, traditionally used for mK-ADR, suffer from chemical instability related to water of crystallization. We report synthesis, characterization as well as low-temperature magnetization and specific heat measurements of two new UHV compatible candidate materials NaYbP$_2$O$_7$ and KYbP$_2$O$_7$. Utilizing the PPMS at 2 K, the ADR of sintered pellets with Ag powder admixture starting at 5 T yields base temperatures (warm-up times) of 45 mK (55 min) and 37 mK (35 min) for NaYbP$_2$O$_7$ and KYbP$_2$O$_7$, respectively, slightly advantageous to KBaYb(BO$_3$)$_2$ (45 mK and 40 min) studied under similar conditions.

description: Soil phosphorus is an essential plant nutrient, and its insufficiency severely limits crop yields. However, its adsorption study plays a vital role in devising appropriate soil phosphorus, “P”, management practices for its use proficiency. This study was initiated to evaluate phosphorous adsorption characteristics and kinetics of soil of three different land uses. A representative topsoil samples (0-20 cm) depth from the forest, grazing, and cultivated lands were collected and weighed 1g of composited soil samples were equilibrated in 20 ml of 0.01 M CaCl2 solution containing KH2PO4 at rates of( 0, 5, 25, 100, 150 and 250) mg P L-1 for assessment of Langmuir adsorption isotherm using batch type experiment. Then, the equilibration time was deduced from the kinetic experiment and fixed at 5 hours. The textural class of soils of forest land was clayey loam, whereas that of grazing and cultivated lands was clayey. Soil pH values under the three land uses were found to be strongly acidic. The experimental soils differed considerably in sorption characteristics under the three land uses. The highest mean value of the product of biding energy and sorption maximum (Kqmax) was recorded in the soil of cultivated land (1.08 Lmg-1) followed by forest land soil (0.7313 Lmg-1), while the lowest was recorded for the soil of grazing land (0.672 Lmg-1), indicating considerable variation soil phosphorus adsorption characteristics under three land-uses. The value of the regression equation (R2) indicated that higher values (R2 > 0.9864) have better soil binding strength than the others. Thus, the good fitness of the model was ascertained by witnessing the R2 values. The kinetic data showed that the values of concentration of soil “P” adsorbed (qe) under the three land uses were closer and the R2 values were comparably lower and almost analogous for the pseudo 1st order kinetic model than the pseudo 2nd order model. Soil “P” sorption kinetics was fast in the first 120 minutes and then showed no change with the increase of the contact time.

Year: 2017

description: This study examines the determinants of commercial banks profitability in Ethiopia by using panel data of thirteen sample commercial banks out of seventeen commercial banks currently operated in Ethiopia over the period 2010-2015.Since the data is secondary in nature, the quantitative research approach was used. Besides, the fixed effect model was used. The factors used in this study include bank size, loan, expense management, revenue diversification, liquidity, capital adequacy and interest income and Return on Asset (ROA) were used to measure the bank's profitability. The findings of the study show that bank size, loan, revenue diversification, capital adequacy and interest income have statistically significant and positive relationship with profitability. On the other hand, expense management (operating expense) has a negative and statistically significant relationship with banks' profitability. However, the relationship between liquidity management and profitability is found to be statistically insignificant. The study suggests management bodies of commercial bank should strive to strengthen the identified significant factor banks size, loan, revenue diversification, capital adequacy and interest income as this will enhance the performance of the banks. Moreover, commercial banks need to invest in recent technologies and management skills which minimize operational expense as this will affect positively on their performance.

Effect of spatial discretization of energy on detonation wave propagation

description: Detonation propagation in the limit of highly spatially discretized energy sources is investigated. The model of this problem begins with a medium consisting of a calorically perfect gas with a prescribed energy release per unit mass. The energy release is collected into sheet-like sources that are now embedded in an inert gas that fills the spaces between them. The release of energy in the first sheet results in a planar blast wave that propagates to the next source, which is triggered after a prescribed delay, generating a new blast, and so forth. The resulting wave dynamics as the front passes through hundreds of such sources is computationally simulated by numerically solving the governing one-dimensional Euler equations in the lab-fixed reference frame. The average wave speed for each simulation is measured once the wave propagation has reached a quasi-periodic solution. Velocities in excess of the CJ speed are found as the sources are made increasingly discrete, with the deviation above CJ being as great as $15\%$. The total energy release, delay time, and whether the sources remain lab-fixed or are convected with the flow do not have a significant influence on the deviation of the average wave speed away from CJ. Such continuous waves can also be shown to have a time-averaged structure consistent with the classical ZND structure of a detonation. In the limit of highly discrete sources, temporal averaging of the wave structure shows that the effective sonic surface does not correspond to an equilibrium state. The average state of the flow leaving the wave in this case does eventually reach the equilibrium Hugoniot, but only after the effective sonic surface has been crossed. Thus, the super-CJ waves observed in the limit of highly discretized sources can be understood as weak detonations due to the non-equilibrium state at the effective sonic surface.

description: Macroscopic assemblies of carbon nanotubes (CNTs) are desirable materials because of the excellent CNT properties. Amongst the methods of production of these CNT materials, the dry-draw fabrication where CNT fibers (CNTFs) are directly pulled out from a CNT forest is known to provide good physical properties. Although it is known that vertical alignment of CNT bundles within the CNT forest is important, the mechanisms behind the dry-draw fabrication of CNTFs are still not completely understood. The simplest known dry-draw model consists of CNT bundles laterally interacting by only van der Waals forces (vdWf). Here, by fully atomistic classical molecular dynamics simulations, we show that the simplest dry-draw model does not produce CNTFs. We also show one important condition for a pair of adjacent CNT bundles to connect themselves under vdWf only and discuss why it leads to the failure of the simplest model.

description: When applied to some models of noncommutative geometry, the formalism of relative locality predicts the occurrence of a delay in the time of arrival of massless particle of different energies emitted by a distant observer. In this letter, we show that this is not the case with Snyder spacetime, essentially because the Lorentz invariance is not deformed in this case. This conclusion is in accordance with the findings of doubly special relativity. Distant observers may however measure different times of flight for massive particle.

description: Stress im Jugendalter ist ein ernstzunehmendes Phänomen des heutigen Zeitalters geworden. Das Leben westlicher Gesellschaften ist geprägt von Schnelligkeit und Selbstkontrolle. Das Resultat sind steigender Leistungs- und Erwartungsdruck. Die Bewältigungsressourcen der Jugendlichen reichen vermehrt nicht mehr aus, diese Belastungen auszugleichen. Das hat Einfluss auf die psychische Gesundheit der Jugendlichen. Die vorliegende Bachelor-Arbeit befasst sich im Kontext gesunder Entwicklung mit der Erhöhung der Schutzfaktoren von Jugendlichen. Es wird der Frage nachgegangen, welchen Mehrwert die Erkenntnisse zu positiven Emotionen im Beratungssetting der Schulsozialarbeit bringen, um die personalen Schutzfaktoren von Jugendlichen zu erhöhen und sie dadurch in ihrer Bewältigungskompetenz zu stärken. Aus dem zusammengetragenen Wissen werden Handlungsempfehlungen für die Schulsozialarbeit abgeleitet. Der erste Teil beschäftigt sich mit dem Phänomens Stress, verschiedener Stressoren und deren Auswirkungen auf Jugendliche. Im Anschluss werden verschiedene Bewältigungskonzepte vorgestellt. Der Fokus verschiebt sich dann auf die Wirkung von positiven Emotionen. Es wird die komplexe Interaktion zwischen Emotionen, Wahrnehmung, Bewertung und Handlungen verdeutlicht. Besonders hervorgehoben wird die Bedeutung und positiver Emotionen sowie individueller Stärken. Der Abschnitt über das Handlungsfeld der Schulsozialarbeit bietet einen Einblick in die Grundprinzipien, Funktionen und methodischen Ansätze Sozialer Arbeit im schulischen Umfeld, mit einer Vertiefung des präventiven Ansatzes. Die anschliessend abgeleiteten Empfehlungen sind praxisorientiert und entlang der Verhaltensprävention mit Jugendlichen ausgerichtet. Ein persönliches Fazit, dass einen kurzen Ausblick mit einschliesst, rundet die Arbeit ab.

The Role of COMESA in Growth and Development of Ethiopia
Creators: name: Mindaye, Fikadu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Researches and different publications used to report that Africa in general and Ethiopia in particular has been registering economic growth in the past five to ten years. Most theories and literatures claim that growth comes either from trade through regional integration or sound macro-economic policies. The main reason to regional integration is to create and divert trade so that there will be considerable gains. Recently seen economic growth of Ethiopia has to be assessed by studying the case of COMESA (as a regional bloc) if it has any role in playing in this growth achievement. This study uses panel data analysis in all 19 member countries during 2003 – 2011 with static linear model regression over 171 observations. Crucial growth indicating variables are injected to the model. Different authors used different methodologies, like CGE and Gravity models to see the bilateral and multilateral effects of regional integration and conclude their findings. By this study the concern is to look into country specific policy and preference effects over the entire observation. So the role of COMESA to Ethiopia would be seen by the effects across variables and observations. Finally based on the analysis conclusions from general to specific scenarios has been derived and policy implications have been sited at the end.

description: We investigate the effect of flow fluctuations, incorporated in non boost-invariant blast-wave model, on kinetic freeze-out parameters of identified hadrons in low energy relativistic heavy-ion collisions. For the purpose of this study, we use the transverse momentum spectra of the identified hadrons produced in central Pb--Pb collisions, at SPS energies ranging from $\rm E_{Lab}=20A-158A $ GeV, and analyze them within a modified non boost-invariant blast wave model. We perform simultaneous fits of the transverse momentum spectra for light hadrons ($π^{-}$, $K^{\pm}$, $p$) and heavy strange hadrons ($Λ$, $\barΛ$, $ϕ$, $Ξ^{\pm}$, $Ω^{\pm}$) seperately. We also fit the transverse momentum spectra of charmonia ($J/Ψ$, $Ψ'$) at $\rm E_{Lab}=158A $ GeV. Our findings suggest that the inclusion of flow fluctuations enhances kinetic freeze-out temperature in case of light and heavy strange hadrons and reduces the corresponding transverse flow velocities. Moreover, we find that the kinetic freeze-out parameters of the charmonia at $\rm E_{Lab}=158A $ GeV are least affected by inclusion of flow fluctuations. Based on this, we make predictions which can provide further insights on the role of flow fluctuations in relativistic heavy-ion collisions.

description: Illegal, unreported, and unregulated (IUU) fishing is a key driver of global overfishing, threatens marine ecosystems, puts food security and regional stability at risk, and is linked to major human rights violations and even organized crime [8]. The ability to predict both where and when IUU fishing is likely occurring provides significant advantages to coast guards with limited resources. In this paper, we provide three resources to aid in the ability to identify IUU fishing. First, we created an algorithm to identify refrigeration ships that often meet with fishing vessels to transport the catch to port. Next, we explored the relationships between these vessels and ports. To do so, we displayed not only the traffic coming and going, but also the statistics surrounding the vessels next visited port via an interactive dashboard. Lastly, we explored an Item Response Theory (IRT) Model that bears a relationship between variables obtained from the fishing vessels’ AIS communication and probability that IUU fishing activity is occurring. We also created and used a Density Based Spatial Clustering of Applications with Noise (DBSCAN) model to explore areas where IUU fishing occurs most often. We approached the problem as an exploratory data problem, with the primary objective of understanding the significance of certain parameters, models, or instances of IUU activity in the data as an initial point of reference for future work.

description: This paper deals with the expectation of monomials with respect to the stochastic area integral $A_{1,2}(t,t+h)=\int_{t}^{t+h}\int_{t}^{s}{\rm d} W_{1}(r){\rm d} W_{2}(s) -\int_{t}^{t+h}\int_{t}^{s}{\rm d} W_{2}(r){\rm d} W_{1}(s)$ and the increments of two Wiener processes, $Δ{W}_{i}(t,t+h)=W_{i}(t+h)-W_{i}(t),\ i=1,2$. In a monomial, if the exponent of one of the Wiener increments or the stochastic area integral is an odd number, then the expectation of the monomial is zero. However, if the exponent of any of them is an even number, then the expectation is nonzero and its exact value is not known in general. In the present paper, we derive formulae to give the value in general. As an application of the formulae, we will utilize the formulae for a careful stability analysis on a Magnus-type Milstein method. As another application, we will give some mixed moments of the increments of Wiener processes and stochastic double integrals.

description: Manipulating the spontaneous emission of a fluorescent emitter can be achieved by placing the emitter in a nanostructured environment. A privileged spot is occupied by plasmonic structures that provide a strong confinement of the electromagnetic field, which results in an enhancement of the emitter-environment interaction. While plasmonic nanostructures have been widely exploited to control the emission properties of single photon emitters, performing the coupling between quantum emitters with plasmons poses a huge challenge. In this Letter we report on a first crucial step towards this goal by the observation of correlated emission between a single CdSe/CdS/ZnS quantum dot exhibiting single photon statistics and a fluorescent nanobead located micrometers apart. This is accomplished by coupling both emitters to a silver nanowire. Single-plasmons are created on the latter from the quantum dot, and transfer energy to excite in turn the fluorescent nanobead.

Role of the road network in the development of Far North Queensland: 1860s to 1960s

description: Far North Queensland covers an area in the tropics that extends roughly from Cardwell on Australia's east coast to the tip of Cape York Peninsula. The city of Cairns is its administrative centre. Europeans first began moving into the inland parts of this reeion in the 1860s but the mountains and tablelands along the eastern hinterland were clothed in thick, tropical rainforest that defied efforts to develop transport routes between inland settlements and potential ports along the east coast. Colonisation could not have occurred without the provision of roads, and colonial and state governments played a leading role in this, driven by the demands of settlers who were both road builders and users. This thesis demonstrates the significance of roads in the development of Far North Queensland from the 1860s to the 1960s. Within the context of the overall pioneer project of which road construction was a key part, it examines the leading role played by government, the technological advances that influenced the development of a road network, the contribution of people who worked on road construction, and the demands of road users that influenced their location and the rate of construction. It posits that the process of developing a road network contributed to the formation of a 'pioneer legend' in Far North Queensland, which had its origins in geographical remoteness and a challenging physical environment.

description: Multi-label recognition (MLR) with incomplete labels is very challenging. Recent works strive to explore the image-to-label correspondence in the vision-language model, \ie, CLIP, to compensate for insufficient annotations. In spite of promising performance, they generally overlook the valuable prior about the label-to-label correspondence. In this paper, we advocate remedying the deficiency of label supervision for the MLR with incomplete labels by deriving a structured semantic prior about the label-to-label correspondence via a semantic prior prompter. We then present a novel Semantic Correspondence Prompt Network (SCPNet), which can thoroughly explore the structured semantic prior. A Prior-Enhanced Self-Supervised Learning method is further introduced to enhance the use of the prior. Comprehensive experiments and analyses on several widely used benchmark datasets show that our method significantly outperforms existing methods on all datasets, well demonstrating the effectiveness and the superiority of our method. Our code will be available at https://github.com/jameslahm/SCPNet.

description: Dust emitted into the air through human activities reduces air quality because it comes along with its deleterious constituents. This study aims to monitor the ambient air quality via the estimation of cadmium and lead concentration in the dust-polluted atmospheric environment using vegetable leaves. Leaves of pumpkin (Telfairia Occidentalis) and green (Amaranthus hybridus) vegetables obtained from Oba, Ekiosa, New Benin, and Ikpoba-Hill markets in Edo State, Nigeria, were washed with de-ionized water, spread, and exposed on tables placed at ten different points, 10 meters apart near the roadside outside and inside each market from 8:00 am to 6:00 pm every day (Monday - Friday) for three months (from November to March). The cadmium and lead pollutants in the dust deposit were analyzed using atomic absorption spectrophotometer after wet digestion of the different collectors. The study revealed that there was no cadmium content in the dust deposited on the vegetable leaves exposed inside each market. Atmospheric dust deposited on the vegetable leaves outside each market had cadmium content up to the tune of ≤0.01mg/kg. The study also revealed that the atmospheric dust inside and outside each market contained lead content. The lead content in the dust deposit obtained from outside each market ranged from 0.03-1.04 mg/kg, and the lead content in the atmospheric dust deposit obtained from inside each market ranged from 0.02-0.69 mg/kg. The air quality index (AQI) prediction for cadmium inside and outside the market atmosphere was very good (very clean). However, for the lead contaminant, the AQI rating outside and inside the market ranged from moderate (fairly clean) to very poor (severely polluted). Ekiosa market was very poor (severely polluted) and the Ikpoba-Hill market was moderate (fairly clean) due to lead contaminants in dust deposited due to human activities and heavy vehicular traffic.

Metastable ferromagnetic clusters in dissipative many-body systems of polar molecules

description: We investigate the effect of two-body loss due to chemical reactions on quantum magnetism of fermionic polar molecules in an optical lattice. We show that an interplay between dissipation and strong long-range interactions leads to formation of metastable ferromagnetic clusters. The spin states of clusters are controlled by interaction parameters and reflect the symmetry of interactions. The size of clusters strongly depends on the initial configuration of molecules due to Hilbert-space fragmentation during dissipative many-body dynamics. We construct an effective model to show the emergence of metastable states as quasi-dark states. Application to quantum simulation of the spin-$S$ Heisenberg model is discussed.
