description: The distribution of money is analysed in connection with the Boltzmann distribution of energy in the degenerate states of molecules. Plots of the population density of income distribution for various countries are well reproduced by a Gamma function, confirming the validity of the statistical distribution at equilibrium. The equilibrium state is reached through pair wise money transference processes, independently of the shape of the initial distribution and also of the detailed nature of the money transactions between the economic agents.

Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: The adoption of Internet of Things (IoT) technologies is increasing and thus IoT is seemingly shifting from hype to reality. However, the actual use of IoT over significant timescales has not been empirically analyzed. In other words the reality remains unexplored. Furthermore, despite the variety of IoT verticals, the use of IoT across vertical industries has not been compared. This paper uses a two-year IoT dataset from a major Finnish mobile network operator to investigate different aspects of cellular IoT traffic including temporal evolution and the use of IoT devices across industries. We present a variety of novel findings. For example, our results show that IoT traffic volume per device increased three-fold over the last two years. Additionally, we illustrate diversity in IoT usage among different industries with orders of magnitude differences in traffic volume and device mobility. Though we also note that the daily traffic patterns of all devices can be clustered into only three patterns, differing mainly in the presence and timing of a peak hour. Finally, we illustrate that the share of LTE-enabled IoT devices has remained low at around 2% and 30% of IoT devices are still 2G only.

description: The concept of quantum computing has inspired a whole new generation of scientists, including physicists, engineers, and computer scientists, to fundamentally change the landscape of information technology. With experimental demonstrations stretching back more than two decades, the quantum computing community has achieved a major milestone over the past few years: the ability to build systems that are stretching the limits of what can be classically simulated, and which enable cloud-based research for a wide range of scientists, thus increasing the pool of talent exploring early quantum systems. While such noisy near-term quantum computing systems fall far short of the requirements for fault-tolerant systems, they provide unique testbeds for exploring the opportunities for quantum applications. Here we highlight the facets associated with these systems, including quantum software, cloud access, benchmarking quantum systems, error correction and mitigation in such systems, and understanding the complexity of quantum circuits and how early quantum applications can run on near term quantum computers.
title: Life imprisonment and prison regime stability
Creators: name: Cullen, James Eric
Publisher: name: The Open University
Year: 1993

description: This research examines the nature of life imprisonment in the British Prison Service with particular reference to the related issues of indeterminacy, regime stability and the ethical implications of current policies. Samples of over 400 inmates and 90 staff in 6 adult and young offender prisons were involved. The author addressed questions concerning the extent to which lifers are distinguishable from non-lifers, produce a stabilising effect on the regimes of their prisons and pay some price as a consequence. The prisons concerned are among those with the highest security classifications which have particular concern not to experience riots or other major acts of concerted indiscipline. Questions which followed from these were to do with both the efficacy and the ethics of either concentrating most lifers, as at present, separating them or determining allocation on a different basis. This cost-benefit perspective also explored the views of Prison Service policy-makers, prison Governors and local staff. The results of interviews, questionnaires and official records are analysed to discern how they bear on the research questions. Final commentary and recommendations are presented within the wider context of the recent (1991) Criminal Justice Bill.

description: We show that integrals of the form \[ \dint_{0}^{1} x^{m}{\rm Li}_{p}(x){\rm Li}_{q}(x)dx, (m\geq -2, p,q\geq 1) \] and \[ \dint_{0}^{1} \frac{\ds \log^{r}(x){\rm Li}_{p}(x){\rm Li}_{q}(x)}{\ds x}dx, (p,q,r\geq 1) \] satisfy certain recurrence relations which allow us to write them in terms of Euler sums. From this we prove that, in the first case for all $m,p,q$, and in the second when $p+q+r$ is even, these integrals are reducible to zeta values. In the case of odd $p+q+r$, we combine the known results for Euler sums with the information obtained from the problem in this form, to give an estimate on the number of {\it new} constants which are needed to express the above integrals for a given weight $p+q+r$. The proofs are constructive, giving a method for the evaluation of these and other similar integrals, and we present a selection of explicit evaluations in the last section.

The Case for Suboxone : A Practice Support Tool for Novice Nurse Practitioners
Creators: name: Minhas, Reena
Publisher: name: The University of British Columbia
Year: 2018

description: Recent data released by the BC Coroners Service attributes 1,422 deaths in 2017 to overdose of illicit drugs in British Columbia (BC) (Office of the Chief Coroner, Ministry of Public Safety & Solicitor General [OCC], 2018). Not only are deaths from drug overdose are largely underreported and therefore underrepresented in statistics, this conservative estimate is expected to continue to rise as toxicology reports continue to result (OCC, 2018). In anticipation of Opiate Agonist Therapy initiation becoming a part of nurse practitioners’ scope of practice in BC, this paper will discuss relevant prescribing guidelines and present a literature review and practice support tool for initiation of buprenorphine-naloxone, a promising option for treatment for Opioid Use Disorder.

description: Following the recent work of Jiang and Lin (Linear Algebra Appl. 585 (2020) 45--49), we present more results (bounds) on Harnack type inequalities for matrices in terms of majorization (i.e., in partial products) of eigenvalues and singular values. We discuss and compare the bounds derived through different ways. Jiang and Lin's results imply Tung's version of Harnack's inequality (Proc. Amer. Math. Soc. 15 (1964) 375--381); our results %with simpler proofs are stronger and more general than Jiang and Lin's. We also show some majorization inequalities concerning Cayley transforms. Some open problems on spectral norm and eigenvalues are proposed.

description: This note presents neutron scattering cross sections for polyethylene at 296 K, 77 K and 4 K derived from a new scattering kernel for neutron scattering off of hydrogen in polyethylene. The kernel was developed in ENDF-6 format as a set of S(alpha,beta) tables using the LEAPR module of the NJOY94 code package. The polyethylene density of states (from 0 to sub eV) adopted to derive the new kernel is presented. We compare our calculated room temperature total scattering cross sections and double differential cross sections at 232 meV at various angles with the available experimental data (at room temperature), and then extrapolate the calculations to lower temperatures (77K and 4K). The new temperature dependent scattering kernel gives a good quantitative fit to the available room temperature data and has a temperature dependence that is qualitatively consistent with thermodynamics.

description: Risk considerations in producer and consumer decision problems have become a subject of increased interest in agricultural economics._ Choices, implying judgments about alternative subjective probability distribution of outcomes, are common for agricultural production units. Factors affected by this aspect of the decision problem include the choice of technique and/or the adoption of new technologies. For decision makers with concave utility functions and low levels of income, the implications of uncertainty for farm decisions may be especially important. In fact, there is evidence from several empirical studies indicating that risk may have been an important factor in slowing down the adoption of Green Revolution technologies in LDC 1s [Roumasset, Anderson].

description: The export competitiveness of three major fruit crops of the Philippines were studied using the domestic resource cost (DRC) method. The DRC estimates were supplemented with perspectives of experts and stakeholders on the impacts of the ASEAN Economic Community (AEC). Trade statistics showed increased trade for these crops among ASEAN members. DRC values also confirmed that domestic production of banana, mango, and pineapple were cost competitive. Sensitivity analysis revealed that raising productivity helps ensure that the competitiveness of these export crops will continue. Furthermore, key informant interviews cited that there is a challenge for domestic production to meet the volume and high quality demanded by export markets. Thus, PCAARRD’s Industry Strategic S&T Plans (ISPs) which target increased yields offer a good starting point in sustaining export competitiveness. Lastly, the country’s potential to serve as a processing and high value-added production hub should be explored as has been shared by experts and industry feedback.

title: Detailed follow-up of hepatitis B surface antigen positive blood donors.
Creators: name: Brown, Susan
Publisher: name: The Open University
Year: 1992

description: Although the North West Thames Region collects over 200,000 blood donations each year, less than four cases of post­ transfusion hepatitis B are reported to us annually (Barbara and Briggs 1981) presumably reflecting the exclusion of approximately 40 donors per annum found to be Hepatitis B surface antigen (HBsAg) positive. This study is the first step in the analysis of some of the unique data accumulated on these HBsAg-positive donations over an eighteen year period. Routine HBsAg screening of all blood donations became mandatory in the U.K. by 1971. Since then, we at the North London Blood Transfusion Centre (NLBTC) have monitored as many HBsAg-positive donors as possible to obtain epidemiological data on HBsAg carriage and the prevalence of other hepatitis B virus (HBV) markers, and to examine ways of predicting the course of HBV infection, so that we can advise carriers concerning their level of infectivity and management of their infection in everyday life. The first section examines the role of HBV in the context of blood transfusion. The serological markers of HBV infection are described in detail, including viral subtypes and a description of mutant and defective strains. The HBV carrier state is then briefly described. The second section describes current microbiological practices in blood transfusion including the present trend towards laboratory automation. The third section details the serological assays available for the laboratory detection of HBV infection and an experimental evaluation defines the confidence we can place upon assay results. Section four is a preliminary analysis of some of the epidemiological data accumulated at the NLBTC over 18 years. 286 HBsAg carriers have been followed up; with particular attention to their HBe antigen and antibody status as the markers most relevant to defining infectivity levels. Of the 35 carriers who were HBeAg-positive at the time of detection, 8 seroconverted from HBe antigen to anti-HBe during the follow-up period. HBeAg positivity was shown to be associated with raised liver function test (LFT) values. Those who seroconverted from HBe antigen to anti-HBe eventually developed normal LFT levels. My preliminary observations on the duration of HBsAg positivity and also on temporal changes in HBsAg titre will form the basis of further work. Although complete in itself, this study also serves as a pilot for a more comprehensive analysis of the wealth of material still to be examined.

description: The strain and electric fields present in free-standing AlGaN/GaN slabs are examined theoretically within the framework of fully-coupled continuum elastic and dielectric models. Simultaneous solutions for the electric field and strain components are obtained by minimizing the electric enthalpy. We apply constraints appropriate to pseudomorphic semiconductor epitaxial layers and obtain closed-form analytic expressions that take into account the wurtzite crystal anisotropy. It is shown that in the absence of free charges, the calculated strain and electric fields are substantially differently from those obtained using the standard model without electromechanical coupling. It is also shown, however, that when a two-dimensional electron gas is present at the AlGaN/GaN interface, a condition that is the basis for heterojunction field-effect transistors, the electromechanical coupling is screened and the decoupled model is once again a good approximation. Specific cases of these calculations corresponding to transistor and superlattice structures are discussed.

description: Tourism is a specialized activity which involves organization and structure. It is an important development and economic factor, as it strengthens the labor market resulting in the fight against unemployment and its elimination, and it promotes cooperation among people, thus ensuring peace. Every society's goal should be sustainable touristic development which requires the preparation of a strategic plan of touristic development. In this context, such a plan should include the creation of a map that captures all touristic resources of a place. Travelers use maps to prepare their routes and the information they get from each map is what ultimately organizes their trip. Thus, the design of each map directly affects the image of a place and highlights whatever its designer choses, with the latter ultimately constituting a crucial factor in the making of the touristic product. The present thesis aims at enhancing the touristic resources of the Municipality of Aristotle of the Regional Unit of Halkidiki through the creation of an interactive map. Its purpose is to promote the tangible and intangible products offered by the Municipality, in order to develop alternative forms of tourism and achieve sustainable development in the specific site.

description: Using a recently developed method to simulate percolation on large clusters of distributed machines [N. R. Moloney and G. Pruessner, Phys. Rev.

Our results are fully consistent with predictions from Conformal Field Theory. We present many new results that await theoretical explanation, particularly for wrapping clusters on a cylinder. We therefore provide possibly the most up-to-date reference for theoreticians working on crossing, spanning and wrapping probabilities in two-dimensional percolation.

description: The COVID-19 epidemic has troubled both medicinal and STEM personnel for more than one year. This epidemic has proven most resilient to medicinal and social measures undertaken worldwide. Trying to model this epidemic is an arduous task, both because of the virus’ mutability and due to the fact that each government trying different measures with a varying degree of success. In this work, we will try to achieve two things. The first one is to create an “umbrella” dynamic system, which can be adjusted to make predictions for all cases, while the second is to transfer this model to a mesoscopic equivalent, in order to make predictions that fit the specificities of smaller populations more accurately. Finally, there will be presented a novel idea for examining whether or not an epidemiological system is closed or open, i.e., the epidemic will end or not.

description: This paper is derived from one of our research mainstream; Research theme: TRAFFIC & TRANSPORTATION PSYCHOLOGY ; TRAVEL PSYCHOLOGY
Abstract:  Travel time perception and learning play a central role in the modeling of day-to-day travel choice dynamics in traffic networks and have attracted the attention of many researchers, specifically for the analysis and operation of intelligent transportation systems and travel demand management scenarios. In this paper, a fuzzy learning model is proposed to capture the mechanism by which travelers update their travel time perceptions from one day to the next, taking into account their experienced travel times. In order to capture travelers’ mental representations of uncertain travel time involving imprecision and uncertainty, a combined artificial neural network and fuzzy logic (neuro-fuzzy) architecture called Adaptive-Network-based Fuzzy Inference System (ANFIS) is employed. This framework, which utilizes a set of fuzzy if-then rules, can serve as a basis for modeling the qualitative sides of travelers’ knowledge and reasoning processes. From the output of this study, the results of our laboratory-like experiment provide a good fit to the stated data of travelers’ behavior, and may reflect the fact that the neuro-fuzzy approach can be considered a promising method in learning and perception updating models. Finally, the proposed learning model is embedded in a microscopic event based simulation framework to evaluate its credibility within a day-to-day behavior of the traffic network. The results of the simulation, which converge to the equilibrium state of the test network, are finally presented, implying that the proposed perception-updating model operates properly.

description: Problem: Alle landwirtschaftlichen Böden beherbergen Lebensgemeinschaften aus Bakterien, Archaeen, Pilzen und Protisten, die gemeinsam das Mikrobiom bilden und mit ihrem Stoffwechsel eine nachhaltige Landwirtschaft ermöglichen und damit die Umwelt schützen (Abbildung 1). Landwirtschaftliches Management könnte jedoch auch unbeabsichtigt negative Aktivitäten des Mikrobioms fördern, wie z.B. die erhöhte Bildung klimaschädlicher Treibhausgase, eine größere Abundanz von Phytopathogenen oder sie könnte zu einer ineffizienten Nutzung von Düngern führen. Lösung: Mikrobiome reagieren sehr empfindlich auf wechselnde Lebensbedingungen, wie sie z.B. durch Bodenbearbeitung oder Düngung verursacht werden. Die landwirtschaftliche Praxis sollte die Vielfalt der Mikrobiome fördern, um die gewünschten Ökosystemdienstleistungen zu stabilisieren (siehe Empfehlungen für die Praxis). Es besteht Forschungsbedarf, um noch gezielter vorteilhafte mikrobieller Aktivitäten messen und fördern zu können.

description: Defect centers are promising candidates for waveguide-integrated silicon light sources. We demonstrate microresonator- and waveguide-coupled photoluminescence from silicon W~centers. Microphotoluminescence measurements indicate wavelengths on-resonance with resonator modes are preferentially coupled to an adjacent waveguide. Quality factors of at least 5,300 are measured, and free spectral ranges closely match expectation. The W~center phonon sideband can be used as a spectral diagnostic for a broader range waveguide-based devices on cryogenic silicon photonic platforms.

description: Η παρούσα διπλωματική εργασία πραγματεύεται το θεσμό της ποινικής διαπραγμάτευσης στην Ελλάδα, αλλά και στις άλλες χώρες, που ο θεσμός εφαρμόζεται. Καθώς τα ποινικά δικαστήρια καθίστανται έμφορτα από ποινικές υποθέσεις κυρίως οικονομικού αντικειμένου, οι εισαγγελείς και οι δικαστές αισθάνονται τη μεγάλη πίεση για την ταχεία επίλυση των υποθέσεων. Είναι γνωστό ότι οι ποινικές δίκες κυρίως με οικονομικό αντικείμενο μπορεί να διαρκέσουν ημέρες, εβδομάδες ή μερικές φορές και μήνες, ενώ με το θεσμό της ποινικής διαπραγμάτευσης μπορεί να οργανωθούν σε σύντομο χρονικό διάστημα και να έχουν αποτέλεσμα. Η απόφαση οποιασδήποτε δίκης είναι πολλές φορές απρόβλεπτη κυρίως για νομικούς ή και ουσιαστικούς λόγους απρόβλεπτο, ενώ με την ποινική διαπραγμάτευση υπάρχει ικανοποίηση όλων των μερών.
description: The present bachelor's thesis deals with institution of plea bargaining in Greece and other countries where the institution takes place. Criminal law courts are full with cases with economic character, prosecutors and judges feel pressured to finish the cases as quickly as possible. It is known that criminal cases with economic character mainly, can last days, weeks even months. With the institution of plea bargaining they can be solved much sooner and have results. The court result many times it’s unpredictable for many reasons. With plea bargaining everyone involved is satisfied.

title: An Analysis of Carrying Behaviour in the Common Marmoset (Callithrix jacchus)
Creators: name: Clarke, Fiona M.
Publisher: name: The Open University
Year: 1991

description: Marmosets (Callithrix jacchus) give birth to infants, usually twins, and the mother can become pregnant again almost immediately, so the female is lactating, to feed the newly born infants, while pregnant. These conditions impose extreme physiological demands upon the mother; all the adult and subadult members of the family help to care for the infants, in many instances, from the day of birth. The adult males and adolescents play a very important role in the care of the infants and in their socialisation.

 The effects of carrying infants on the behaviour of the mother and the other caregivers were investigated. Identified members of families of marmosets were observed in the first two weeks after the infant's birth, and again in the fifth to sixth weeks of their life. The movements of the caregivers were quantified, as were the duration of the carrying bouts. Carrying one infant and carrying as a pair were scored individually. Carrying infants was found to have a profound effect upon their mobility and activity levels. The adults, and subadult siblings, tended to carry the infants as a pair rather than consecutively. In this way the caregivers, although burdened by the infants, may be maximising the time spent in enforced in activity by carrying the infants together.

description: We report extensive molecular-dynamics simulation results for binary mixtures of hard spheres for different size disparities and different mixing percentages,for packing fractions up to 0.605 and over a characteristic time interval spanning up to five orders in magnitude. We explore the changes in the evolution of glassy dynamics due to mixing and discover two opposite scenarios: for large size disparity, increasing the mixing percentage of small particles leads to a speed-up of long-time dynamics, while small disparity leads to a slowing down. These results agree with predictions based on the mode coupling theory for ideal glass transitions.

description: A universal relation between the leading correction to the entropy and extremality was gotten in the work of Goon and Penco. In this paper, we extend this work to the massive gravity and investigate thermodynamic extremality relations in a topologically higher-dimensional black hole. A rescaled cosmological constant is added to the action of the massive gravity as a perturbative correction. This correction modifies the extremality bound of the black hole and leads to the shifts of the mass, entropy, etc. The Goon-Penco relation is gotten. Regarding the cosmological constant as a variable related to pressure, we get the thermodynamic extremality relations between the mass and pressure, charge, parameters $c_i$ by accurate calculations, respectively. Finally, these relations are verified by a triple product identity, which shows that the universal relation exists in black holes.

description: Cyclists and pedestrians account for a significant share of fatalities and serious injuries in the road transport system. In order to protect them, advanced driver assistance systems are being developed and introduced to the market, including autonomous emergency braking and steering systems (AEBSS) that autonomously perform braking or an evasive manoeuvre by steering in case of a pending collision, in order to avoid the collision or mitigate its severity. This study proposes a new prospective framework for quantifying safety benefit of AEBSS for the protection of cyclists and pedestrians in terms of saved lives and reduction in the number of people suffering serious injuries. The core of the framework is a novel application of Bayesian inference in such a way that prior information from counterfactual simulation is updated with new observations from real-world testing of a prototype AEBSS. As an illustration of the method, the framework is applied for safety benefit assessment of the AEBSS developed in the European Union (EU) project PROSPECT. In this application of the framework, counterfactual simulation results based on the German In-Depth Accident Study Pre-Crash Matrix (GIDAS-PCM) data were combined with results from real-world tests on proving grounds. The proposed framework gives a systematic way for the combination of results from different sources and can be considered for understanding the real-world benefit of new AEBSS. Additionally, the Bayesian modelling approach used in this paper has a great potential to be used in a wide range of other research studies.

description: Emission of gamma rays by the processes of bremsstrahlung and inverse Compton scattering (CS) from interactions of short ultra-intense I ≈ 1021 − 1023 W/cm2 laser pulses with thin solid foils are studied using particle-in-cell (PIC) simulations. A module for simulating bremsstrahlung has been implemented in the PIC loop to self-consistently account for the dynamics of the laser–plasma interaction, plasma expansion, and the emission of gamma ray photons. This module made it possible to study emission from thin targets, where recirculation of hot electrons plays an important role. It is shown that the angular distribution of the bremsstrahlung photons exhibits a four-directional structure with the angle of emission decreasing with the increase of the width of the target, directly related to the increase of hot electron divergence during their recirculation, while that of the CS photons has a forward-oriented two-directional structure centred at an angle θ = ±30°, a value predicted by a theoretical model based on a standing wave approximation to the electromagnetic field in front of the target, which only increases at the highest intensities due to faster hole boring, which renders the approximation invalid. The conversion efficiency of the energy of the laser pulse to the energy of the bremsstrahlung gamma rays rises with both the driving pulse intensity, and the thickness of the target. The CS emission is unaffected by the thickness of the target, but exhibits a super-linear increase with the driving pulse intensity. The amount of bremsstrahlung gamma rays also increases with the atomic number of the target material, despite a lower absorption of the driving laser pulse. On the other hand, the higher absorption, further enhanced by faster hole boring, in the targets with lower atomic number strongly favours the CS process. Since reaching the extreme intensities I > 1022 W/cm2, where the CS process dominates over bremsstrahlung, using the contemporary and near-future lasers will likely require the laser pulse to be tightly focused, the effect of tight focusing on CS emission is examined. It is shown that in terms of conversion efficiency, there is an optimum focal spot size, roughly equal to the laser wavelength, but that the interaction is extremely sensitive to the longitudinal positioning of the target for such small spot sizes.

description: The far-infrared absorption in two-dimensional electron layers subject to magnetic field of general orientation was studied theoretically. The Kubo formula is employed to derive diagonal components of the magneto-conductivity tensor of two-dimensional electron single-layers and double-layers. The parabolic quantum well is used to model a simple single-layer system. Both single-layer and double-layer systems can be realized in a pair of tunnel-coupled, strictly two-dimensional quantum wells. Obtained results are compared to experimental data.
