description: Quantifying behaviors of robots which were generated autonomously from task-independent objective functions is an important prerequisite for objective comparisons of algorithms and movements of animals. The temporal sequence of such a behavior can be considered as a time series and hence complexity measures developed for time series are natural candidates for its quantification. The predictive information and the excess entropy are such complexity measures. They measure the amount of information the past contains about the future and thus quantify the nonrandom structure in the temporal sequence. However, when using these measures for systems with continuous states one has to deal with the fact that their values will depend on the resolution with which the systems states are observed. For deterministic systems both measures will diverge with increasing resolution. We therefore propose a new decomposition of the excess entropy in resolution dependent and resolution independent parts and discuss how they depend on the dimensionality of the dynamics, correlations and the noise level. For the practical estimation we propose to use estimates based on the correlation integral instead of the direct estimation of the mutual information using the algorithm by Kraskov et al. (2004) which is based on next neighbor statistics because the latter allows less control of the scale dependencies. Using our algorithm we are able to show how autonomous learning generates behavior of increasing complexity with increasing learning duration.

Controlled Vocabularies in Colectica
Creators: name: Iverson, Jeremy
Publisher: name: Zenodo
Year: 2021

description: A controlled vocabulary is an organized set of terms. Controlled vocabularies make it easier to make information consistent. They also improve indexing and searching for information. DDI Lifecycle supports using controlled vocabularies for many of its metadata fields.

 Colectica 6.2 adds support for controlled vocabularies in its desktop and Web tools. Administrators can configure which vocabulary to use for specific content fields. Users can choose terms from the appropriate vocabulary when editing content.

 Vocabularies are specified as DDI Lifecycle code lists. DDI code lists allow specifying the values and terms of a vocabulary in one or more languages. Organizations can register these code lists in a metadata repository for persistence and revision tracking.

 Colectica can import vocabularies from the Simple Knowledge Organization System (SKOS). The Consortium of European Social Science Data Archives (CESSDA) runs a vocabulary service, providing 28 vocabularies in more than 10 languages. These vocabularies are downloadable in SKOS format. This presentation will show how all these vocabularies can integrate with DDI Lifecycle and the Colectica software. Recorded version of this talk: https://youtu.be/2DGOooUQDjQ

description: Understanding the conditions ensuring the persistence of a population is an issue of primary importance in population biology. The first theoretical approach to the problem dates back to the 50's with the KiSS (after Kierstead, Slobodkin and Skellam) model, namely a continuous reaction-diffusion equation for a population growing on a patch of finite size $L$ surrounded by a deadly environment with infinite mortality -- i.e. an oasis in a desert. The main outcome of the model is that only patches above a critical size allow for population persistence. Here, we introduce an individual-based analogue of the KiSS model to investigate the effects of discreteness and demographic stochasticity. In particular, we study the average time to extinction both above and below the critical patch size of the continuous model and investigate the quasi-stationary distribution of the number of individuals for patch sizes above the critical threshold.

Prioritizing core competencies for food systems leadership
Creators: name: Bryan, Michael Jerome
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Approaches to leadership development often center on the development of leadership competencies. The Food Systems Leadership Institute (FSLI) is a leadership development program that seeks to develop leadership competencies in personal leadership, organizational change, and food systems leadership. This study uses an expert panel made up of subjects with experience and expertise in leadership, including leadership in food system organizations to examine whether all 24 of the FSLI's core competencies are of equal importance. After two rounds of surveys using the Delphi technique descriptive statistics and comments of panel members suggest that the core competencies are not equally important and can be prioritized. Self understanding and reflection, visioning, defining and understanding organizational culture, and including/engaging diverse constituents of the food system were among the most important competencies.
Is diversity our strength?

description: A prominent characteristic of the city of Toronto is its increasing diversity, with half of the city’s population being foreign-born. While the concept of diversity appeals to Toronto’s reputation as a multi-cultural haven, the city’s approach to managing diversity is becoming increasingly instrumentalist, i.e. diversity is considered an asset as long as its benefits are economically valuable. As a result, inner-city neighbourhoods in Toronto are thriving due to development projects and services, while the most diverse neighbourhoods in the inner-suburbs are left in a dire state. This article presents an analysis of how the concept of diversity used within policy euphemises systemic discrimination and inequality based on race, class and gender. It serves to reveal the mismatch between policy rhetoric on diversity and its materialisation in the daily lives of the inhabitants of a low-income Toronto innersuburb, by juxtaposing policy discourses with inhabitants’ everyday experiences. By illustrating how inhabitants reproduce negative essentialised stereotypes based on diversity markers, the article argues that talking diversity as an alternative to or an escape from problematising the intertwined systems of race, class and gender oppression, could potentially serve to perpetuate them.

description: Diversity has increasingly emerged as the core focus of many studies concerning factors impacting on social cohesion. Various scholars have concluded that diversity is detrimental to cohesion. Most of this research, however, draws generalisations based upon quantitative data and fails to account for the impact of inequality, segregation and discrimination, and their interconnectedness to diversity. This research provides an in-depth qualitative analysis of the perceptions of inhabitants of a diverse Toronto neighbourhood regarding formal and informal interactions, common values and attachment. The findings suggest that the internalisation of gendered and class-based racism by inhabitants plays a crucial role in shaping perceptions and interactions.

description: We are observing, thanks to ALMA, the dust distribution in the region of active planet formation around young stars. This is a powerful tool to connect observations with theoretical models and improve our understandings of the processes at play. We want to test how a multi-planetary system shapes its birth disk and study the influence of the planetary masses and particle sizes on the final dust distribution. Moreover, we apply our model to the HL Tau system in order to obtain some insights on the physical parameters of the planets that are able to create the observed features. We follow the evolution of a population of dust particles, treated as Lagrangian particles, in two-dimensional, locally isothermal disks where two equal mass planets are present. The planets are kept in fixed orbits and they do not accrete mass. The outer planet plays a major role removing the dust particles in the co-orbital region of the inner planet and forming a particle ring which promotes the development of vortices respect to the single planetary case. The ring and gaps width depends strongly on the planetary mass and particle stopping times, and for the more massive cases the ring clumps in few stable points that are able to collect a high mass fraction. The features observed in the HL Tau system can be explained through the presence of several massive cores that shape the dust disk, where the inner planet(s) should have a mass on the order of 0.07 Jupiter masses and the outer one(s) on the order of 0.35 Jupiter masses. These values can be significantly lower if the disk mass turns out to be less than previously estimated. Decreasing the disk mass by a factor 10 we obtain similar gap widths for planets with a mass of 10 and 20 Earth masses respectively. Although the particle gaps are prominent, the expected gaseous gaps would be barely visible.

Control of Super-Efficient Dew-Point Evaporative Cooler
Creators: name: Haggag, Osama
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Most of the electricity consumed in buildings is used by heating, cooling, and air conditioning units. Many novel devices based on renewable energy were implemented for heating purposes in recent years. However, there are no devices based on renewable energy which have been widely applied in the cooling sector. One of the novel solutions is evaporative air cooling (IEC). Evaporative air coolers utilize the latent heat of the water to provide cooling energy and therefore are less dependent on fossil fuels. They are also characterized by much higher COP factors in comparison to mechanical compression systems. The most effective method of evaporative cooling is based on the technology called Dew-Point Cooling (DPC). However, traditional DPC systems have some limitations such as efficient operation in dry air, excessive water consumption, ineffective water distribution and the absence of temperature and humidity controls etc. In this research, control for a new DPC design, which overcomes all these disadvantages and takes cooling technology to a completely new level, is developed. In the proposed system, temperature and relative humidity are controlled to save energy without reducing the comfort of the environment. Sensor data obtained from the room, atmosphere and cooler are evaluated in the developed control software and control actions are sent to actuators such as fans, vacuum pump, and water pump. With this independent control strategy, more efficient energy use will be achieved in accordance with comfort criteria. Moreover, the proposed solution provides some other advantages such as COPs on the level of 12.5 in humid climatic conditions, no external water consumption, and a novel effective water distribution system for effective water supply. The system allows over 80% energy savings in comparison to traditional systems, while providing the same level of comfort for the occupants in a wide range of outdoor conditions. In this research, control logic for the proposed system is developed using MATLAB/Simulink and software results are obtained, a hardware-in-the-loop (HIL) test is then conducted, real-time results are obtained and compared to the results obtained from software testing. To further increase efficiency of the system, Internet of Things (IoT) technology is implemented in the control logic to allow for data analysis, data storage, and most importantly, data monitoring to correct any errors that may occur. It is worth noting that a total of two journal publications were published during this study and a lot of the text is used throughout this paper.

description: When the surface of a nominally flat binary material is bombarded with a broad, normally-incident ion beam, disordered hexagonal arrays of nanodots can form. Shipman and Bradley have derived equations of motion that govern the coupled dynamics of the height and composition of such a surface [P. D. Shipman and R. M. Bradley, Phys. Rev. B 84, 085420 (2011)]. We investigate the influence of initial conditions on the hexagonal order yielded by integration of those equations of motion. The initial conditions studied are hexagonal and sinusoidal templates, straight scratches and nominally flat surfaces. Our simulations indicate that both kinds of template lead to marked improvements in the hexagonal order if the initial wavelength is approximately equal to or double the linearly selected wavelength. Scratches enhance the hexagonal order in their vicinity if their width is close to or less than the linearly selected wavelength. Our results suggest that prepatterning a binary material can dramatically increase the hexagonal order achieved at large ion fluences.

Effect of canakinumab on clinical and biochemical parameters in acute gouty arthritis: A Meta-analysis
Creators: name: Jena, Monalisa
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Medicine and Health Sciences

description: Gout is an autoinflammatory disease associated with increased blood levels of urate and subsequently deposition of monosodium urate crystals in and around joints. Recently, gout has become one of the most common causes of inflammatory arthritis with increasing prevalence rate in industrialised countries. The burden of gout is substantial; joint flares, tophi, polyarticular involvement, and chronicity deeply impact patients' quality of life and workability. And, gout is an independent risk factor for cardiac and all-cause morbidity and mortality. Monosodium urate crystals can trigger the release of pro inflammatory cytokines, in particular, interleukin-1β (IL-1β). Acute gout is traditionally treated with NSAIDs, corticosteroids, and colchicine. However, subjects have multiple comorbidities that limit the use of some conventional therapies. Chronically, urate-lowering therapies (ULTs) reduce urate stores and, when combined with anti-inflammatory prophylaxis, reduce the risk of new flares. The comorbidities associated with the anti- inflammatory agents used for the treatment such as hypertension, diabetes mellitus, renal insufficiency and cardiovascular disease may worsen the disease by frequent flares and persistent inflammation which ultimately contribute to the joint destruction and quality of life. Current treatment is first based on lifestyle measures and then on a pharmacological approach. As IL-1β is the key mediator in gouty arthritis inflammation, targeted anti-IL-1β therapy may be a valuable option for the management of gouty arthritis. Canakinumab, a fully human anti-IL-1β monoclonal antibody with a long plasma half-life (3–4 weeks) has shown superior efficacy (more rapid and sustained pain relief and significant reduction in risk of new flares) to triamcinolone acetonide (TA) in a dose-ranging study in patients with acute gouty arthritis. Despite many treatment options available for management of acute gouty arthritis, incomplete pain relief and chance of new flare has led to the exploration of alternatives. Canakinumab, human anti-IL-1β monoclonal antibody is being studied as one of the options for treatment of acute gouty arthritis. Although few clinical trials have been conducted in this regard with results favouring Canakinumab, a meta- analysis will help quantifying the magnitude of the effect of Canakinumab in patients of acute gouty arthritis. We are therefore conducting this meta-analysis to establish a conclusive role of Canakinumab in gouty arthritis.

On the structure of graphs with forbidden induced substructures
Creators: name: Weber, Lea
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2023

description: One of the central goals in extremal combinatorics is to understand how the global structure of a combinatorial object, e.g. a graph, hypergraph or set system, is affected by local constraints. In this thesis we are concerned with structural properties of graphs and hypergraphs which locally do not look like some type of forbidden induced pattern. Patterns can be single subgraphs, families of subgraphs, or in the multicolour version colourings or families of colourings of subgraphs. Erdős and Szekeres's quantitative version of Ramsey's theorem asserts that in every $2$-edge-colouring of the complete graph on $n$ vertices there is a monochromatic clique on at least $\frac{1}{2}\log n$ vertices. The famous Erdős-Hajnal conjecture asserts that forbidding fixed colourings on subgraphs ensures much larger monochromatic cliques. The conjecture is open in general, though a few partial results are known. The first part of this thesis will be concerned with different variants of this conjecture: A bipartite variant, a multicolour variant, and an order-size variant for hypergraphs. In the second part of this thesis we focus more on order-size pairs; an order-size pair $(n,e)$ is the family consisting of all graphs of order $n$ and size $e$, i.e. on $n$ vertices with $e$ edges. We consider order-size pairs in different settings: The graph setting, the bipartite setting and the hypergraph setting. In all these settings we investigate the existence of absolutely avoidable pairs, i.e. fixed pairs that are avoided by all order-size pairs with sufficiently large order, and also forcing densities of order-size pairs $(m,f)$, i.e. for $n$ approaching infinity, the limit superior of the fraction of all possible sizes $e$, such that the order-size pair $(n,e)$ does not avoid the pair $(m,f)$.

description: Shrinking populations have been gaining increasing attention, especially in postsocialist East and Central European countries. While most studies focus on specific cities and regions, much less is known about the spatial dimension of population decline on the national level and the local factors determining spatially uneven population change. This study uses Lithuanian census data from the years 2001 and 2011 to get insight into the geography of population change for the whole country. Lithuania has experienced one of the highest rates of population decline in the world in the last decades. The predictive models show that regional factors have a strong effect on the variation in population change throughout the country but also reveal that sociodemographic and economic area characteristics play a role in the process of decline. Our results give little hope to those who would like to reverse the ongoing trends of population change and emphasize the need for spatial planning to cope with the changes. This is an approach which currently does not exist in practice in Lithuania.

Association Between Quadriceps Strength and Tibiofemoral Cartilage Proteoglycan Density at 6 Months Following Anterior Cruciate Ligament Reconstruction
Creators: name: Hunt, Christian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Anterior Cruciate ligament (ACL) injury is common in the active population. ACL Reconstruction (ACLR) is used to restore stability and allow for return to activity post-ACL injury. A common impairment following ACLR is decreased quadriceps strength in the injured limb, which has been linked to the development of Tibiofemoral Osteoarthritis (OA). Compositional magnetic resonance imaging (MRI) has shown the ability to identify early cartilage changes prior to cartilage structural damage. This preliminary investigation evaluated the association between isometric quadriceps strength and T1rho compositional MRI in weight-bearing regions of tibiofemoral cartilage in 24 subjects at 6 months post-ACLR. We found evidence of compositional changes, measured via T1rho relaxation time, with little change to cartilage volume. There was also a statistically significant association between quadriceps strength and T1rho relaxation times for the three regions of the medial femoral condyle, calling for additional research into the interaction of quadriceps and cartilage composition.
Restoring broken entanglement by separable correlations

description: We consider two bosonic Gaussian channels whose thermal noise is strong enough to break bipartite entanglement. In this scenario, we show how the presence of separable correlations between the two channels is able to restore the broken entanglement. This reactivation occurs not only in a scheme of direct distribution, where a third party (Charlie) broadcasts entangled states to remote parties (Alice and Bob), but also in a configuration of indirect distribution which is based on entanglement swapping. In both schemes, the amount of entanglement remotely activated can be large enough to be distilled by one-way distillation protocols.

description: Nitrogen vacancy (NV) centers can couple to confined phonons in diamond mechanical resonators via the effect of lattice strain on their energy levels. Access to the strong spin-phonon coupling regime with this system requires resonators with nanoscale dimensions in order to overcome the weak strain response of the NV ground state spin sublevels. In this work, we study NVs in diamond cantilevers with lateral dimensions of a few hundred nm. Coupling of the NV ground state spin to the mechanical mode is detected in electron spin resonance (ESR), and its temporal dynamics are measured via spin echo. Our small mechanical mode volume leads to a 10-100X enhancement in spin-phonon coupling strength over previous NV-strain coupling demonstrations. This is an important step towards strong spin-phonon coupling, which can enable phonon-mediated quantum information processing and quantum metrology.

Population decline in Lithuania

Year: 2018

description: Since the 1990s, Lithuania lost almost one-quarter of its population, and some regions within the country lost more than 50% of their residents. Such a sharp population decline poses major challenges to politicians, policy-makers and planners. The aim of this study is to obtain more insight into the recent processes of socio-spatial change and the role of selective migration in Lithuania. The main focus is on understanding who lives in those regions which are rapidly losing population, and who is most likely to leave these regions. This is one of the first studies to use individual-level Lithuanian census data from 2001 and 2011. We found that low socio-economic status residents and older residents dominate the population of shrinking regions, and unsurprisingly that the most ‘successful’ people are the most likely to leave such regions. This process of selective migration reinforces the negative downward spiral of declining regions. As a result, socio-spatial polarization is growing within the country, where people with higher socio-economic status are increasingly overrepresented in the largest city-regions, while the elderly and residents with a lower socio-economic status are overrepresented in declining rural regions. This paper provides empirical evidence of selective migration and increasing regional disparities in Lithuania. While the sociospatial changes are obvious in Lithuania, there is no clear strategy on how to cope with extreme population decline and increasing regional inequalities within the country.

description: We use electoral data to analyze the ethno-political consequences that may arise from the fact that the region surrounding the city of Vilnius is dominated by residents with a Polish identity, while those who move to the suburbs are mainly ethnic Lithuanians. In the suburban ring we found increasing voting turnout, a decreasing share of votes for the Polish party, and an increase of the absolute number of votes for this party. The changing electoral behavior might be an indicator of growing ethno-political tensions and the zones of the most intense changes identify areas of potential social tensions between ethnic groups.

description: We present results from recent time-of-flight nuclear mass measurements at the National Superconducting Cyclotron Laboratory at Michigan State University. We report the first mass measurements of 48Ar and 49Ar and find atomic mass excesses of -22.28(31) MeV and -17.8(1.1) MeV, respectively. These masses provide strong evidence for the closed shell nature of neutron number N=28 in argon, which is therefore the lowest even-Z element exhibiting the N=28 closed shell. The resulting trend in binding-energy differences, which probes the strength of the N=28 shell, compares favorably with shellmodel calculations in the sd-pf shell using SDPF-U and SDPF-MU Hamiltonians.

description: The city of Vilnius has experienced major shifts in occupational structure between 2001 and 2011 and at the same time there were major transitions in the housing market and suburbanization. The main aim of this chapter is to get more insight in recent socio-economic segregation processes in Vilnius. We used occupational groups as a proxy for socio-economic status, and census tract level data to measure segregation in Vilnius and its three main housing zones during 2001 and 2011. Notwithstanding the major economic and social changes of post-communist society, we found low levels of segregation and modest change during the last decade. Local patterns of segregation were explored using location quotient maps. The analyses illustrated a deepening social divide in the city between the relatively rich north and the poorer south of the city, but the inner city changes are somehow ambiguous. In this chapter we argue that the main factors of socio-spatial change in Vilnius are related to an exceptionally high share of housing estates in the city and the polycentric urban system of the country. Together with 'fast-track' reforms after 1990 this urban system gave a unique character to the current processes and patterns of segregation.

description: Lattice models of fermions, bosons, and spins have long served to elucidate the essential physics of quantum phase transitions in a variety of systems. Generalizing such models to incorporate driving and dissipation has opened new vistas to investigate nonequilibrium phenomena and dissipative phase transitions in interacting many-body systems. We present a framework for the treatment of such open quantum lattices based on a resummation scheme for the Lindblad perturbation series. Employing a convenient diagrammatic representation, we utilize this method to obtain relevant observables for the open Jaynes-Cummings lattice, a model of special interest for open-system quantum simulation. We demonstrate that the resummation framework allows us to reliably predict observables for both finite and infinite Jaynes-Cummings lattices with different lattice geometries. The resummation of the Lindblad perturbation series can thus serve as a valuable tool in validating open quantum simulators, such as circuit-QED lattices, currently being investigated experimentally.

Effect of minor SNPs on enzymatic activity regulated by common human haplotypes of the catechol-O-methyltransferase gene

description: Three common haplotypes of the human catechol-O-methyltransferase (COMT) gene are associated with experimental pain sensitivity. Based on subjects' pain responsiveness, haplotypes were designated as low (LPS), average (APS), or high (HPS) pain sensitive; APS and HPS haplotypes exhibit lower COMT enzymatic activity. Minor frequency SNPs naturally occur within the APS and HPS haplotypes, but their functional impact is unknown. We hypothesized that these minor SNPs, one occurring in the APS construct (G/A, rs769224) and three in the HPS construct (G/T, rs6267; G/A, rs740602; C/T, rs8192488), may compensate for the observed reductions in enzymatic activity. Testing was carried out via transient transfection of rat adrenal (PC-12) cells with each of the four constructs. No difference exists between the haplotype mutants and their respective parent haplotype for RNA abundance, protein expression, or enzymatic activity (P > 0.05). Additionally, the minor allele of SNP re6267 is a likely marker of the HPS haplotype.

description: The hygro-mechanical behavior of a hierarchical cellular material, i.e. growth rings of softwood is investigated using a two-scale micro-mechanics model based on a computational homogenization technique. The lower scale considers the individual wood cells of varying geometry and dimensions. Honeycomb unit cells with periodic boundary conditions are utilized to calculate the mechanical properties and swelling coefficients of wood cells. Using the cellular scale results, the anisotropy in mechanical and swelling behavior of a growth ring in transverse directions is investigated. Predicted results are found to be comparable to experimental data. It is found that the orthotropic swelling properties of the cell wall in thin-walled earlywood cells produce anisotropic swelling behavior while, in thick latewood cells, this anisotropy vanishes. The proposed approach provides the ability to consider the complex microstructure when predicting the effective mechanical and swelling properties of softwood.
Socio-ethnic segregation in the metropolitan areas of Lithuania

description: One of the specific features of many post-Soviet cities is their multi-ethnic structure, which was strongly influenced by internal migrations within the Soviet Union. Political and economic reforms in the 1990s led to changes in ethnic composition, and the attention given to the processes of ethnic-segregation has started to increase. While most studies focus on capital cities, much less is known about second-tier cities. This article examines the interrelationships between ethnic and social segregation in the metropolitan areas of Lithuania (Vilnius, Kaunas, Klaipėda). The authors use Lithuanian census data from the years 2001 and 2011 to obtain insight into the recent changes in the socio-spatial differentiation of the largest ethnic groups: Lithuanians, Poles, and Russians. The results show a clear relationship between the socio-economic and ethnic status of the residents of metropolitan areas and, therefore, suggest that ethnic segregation is strongly linked to the general processes of social segregation. The findings also show that the higher the proportion of a certain ethnic minority group in an area, the higher the proportion of lower (social) status residents in this group. In addition, in such cases, ethnic minorities often tend to concentrate in particular areas within the cities.

description: Integrated metadata catalogues and sharing metadata across all disciplines are needed to allow scientists and machines to collaborate across borders and disciplines in finding research data. The FAIRsFAIR project has been working on metadata integration pilot. The pilot includes integration of social science metadata into the generic research discovery system B2FIND which is part of the EUDAT CDI and therefore a central indexing tool for EOSC-hub. At the same time, CESSDA ERIC has been developing an open OAI-PMH API endpoint (called CESSDA Metadata Aggregator) to expose the metadata from the CESSDA Data Catalogue. Therefore, the decision was made to harvest CESSDA DDI Codebook 2.5 metadata records into B2FIND using the beta version of the Aggregator. Our presentation will describe the work done, the selections made, and the findings from this pilot. We will also discuss the benefits and challenges of harvesting metadata records from various sources, experiences on DDI, and the possible ways forward.

description: We report ultra-low phase-noise microwave generation at a 9.6 GHz carrier frequency from optical frequency combs based on diode-pumped solid-state lasers emitting at telecom wavelength and referenced to a common cavity-stabilized continuous-wave laser. Using a novel fibered polarization-maintaining pulse interleaver, a single-oscillator phase-noise floor of -171 dBc/Hz has been measured with commercial PIN InGaAs photodiodes, constituting a record for this type of detector. Also, a direct optical measurement of the stabilized frequency combs timing jitter was performed using a balanced optical cross correlator, allowing for an identification of the origin of the current phase-noise limitations in the system.

title: Resource Allocation in Drone-Assisted Emergency Communication Systems
Creators: name: Chen, Tianqi
Publisher: name: University of Kent

description: Due to low cost and high mobility, drones are considered important in emergency communications. In this thesis, we consider a unique drone assisted emergency communication system used in disaster scenarios, where the drone with limited power acts as a relay to improve the downlink sum rate through rational resource allocation. The wireless channel model between drones and ground users in emergency communications is different from conventional relay networks, while drones have their coverage area and data rate limits. Considering these specific characteristics, we formulate a joint power and subcarrier allocation problem to maximize data rate of users, which is limited by the transmit power budget per drone and the number of users on each subcarrier in emergency communications. However, resource allocation in a unique drone assisted emergency communication system is a nondeterministic polynomial time (NP)-hard problem requiring brute force search, which has prohibitive computational complexity. Instead, efficient algorithms that provide a good trade-off between system performance and implementation practicality are needed. The contributions of this thesis are proposing two different resource allocation schemes. Both schemes divide users into high-priority(HP) users and low-priority(LP) users and both guarantee minimum guaranteed rate for HP users. The first scheme is an adaptive algorithm with low complexity. In this scheme, a suboptimal solution is proposed by dividing users into two priority groups: HP users (rescuers) and LP users (affected people). This procedure achieves quasi-linear complexity in terms of the number of users. Finally, the data of the brute force search method and this method were collected through simulation experiments. The data shows that the data rate of the proposed scheme was very close to the optimal data rate when there was a lack of resources. The second scheme is an adaptive algorithm. In the proposed scheme, we formulate a joint power and subcarrier allocation problem to maximize data rate of users, which is limited by the transmit power budget per drone and the number of users on each subcarrier in emergency communications. Due to the intractability of the formulated problem, it is decomposed into two sub-problems: power allocation optimisation and subcarrier allocation optimization. Then a joint resource allocation algorithm is proposed. The simulation results show that the performance of the proposed method is close to that of the optimal solution but with much lower complexity.

description: We establish that, under certain closure assumptions on a pseudovariety of semigroups, the corresponding relatively free profinite semigroups freely generated by a non-singleton finite set act faithfully on their minimum ideals. As applications, we enlarge the scope of several previous join irreducibility results for pseudovarieties of semigroups, which turn out to be even join irreducible in the lattice of pseudovarieties of ordered semigroups, so that, in particular, they are not generated by proper subpseudovarieties of ordered semigroups. We also prove the stronger form of join irreducibility for the Krohn-Rhodes complexity pseudovarieties, thereby solving a problem proposed by Rhodes and Steinberg.
