title:  The G5 Sahel: An Insufficient Organization for a Failed Region?
Creators: name: El Khou, Beder Dine
Publisher: name: Old Dominion University Libraries
Year: 2019

description: In the wake of mass kidnapping and terrorist attacks launched by Boko Haram and other extremist groups in the Sahel of West Africa, along with the rise of the Islamic State in Libya that started to have immediate impact on the Sahel’s already problematic situation, five states from the region of Sahel decided to create a coalition in 2014 not only to fight insurgencies rampaging in the area but also to work on the development of the region. With a very small capacity in terms of man power and equipment, the G5 Sahel coalition attempts to achieve what other intervening entities had not been able to achieve. Long before the coalition was formed, numerous organizations and operations led by powerful states and institutions were deployed to tackle instabilities and other related issues such as poverty and migration, but they all have been in vain. The resilience of the problems plaguing Sahel had deep roots in the historical, environmental, cultural and political. The G5 Sahel has been more of a failure than a success for two main reasons: 1) The member states themselves are suffering from different internal issues which significantly inhibits any collective initiative 2) It is too insufficient to tackle such a complex situation given its current personnel, financial and equipment capacities. The Sahel, however, is a promising region with an abundance of resource and a growing population young that will make a world top market place. And global power will definitely benefit from fixing and investing in the region.

description: The development of optical metamaterials has resulted in the demonstration of remarkable physical properties, including cloaking, optical magnetism, and negative refraction. The latter has attracted particular interest, mainly because of its promise for super-resolution imaging. In recent years, negative refraction has been demonstrated with plasmonic materials and nonlinear discrete elements. However, the widespread use of negative refraction at optical frequencies is limited by high losses and strong dispersion effects, which typically limits operation to narrow frequency bands. Here we use degenerate four-wave mixing (d-4WM) to demonstrate controllable negative refraction at a graphene interface, which acts as a highly efficient phase-conjugating surface. The scheme has very low loss because of the very small thickness of the nonlinear material and it ensures broadband operation due to the linear bandstructure of graphene.
A Historical Investigation of Ethiopia’s Claims over Djibouti

description: Using the British Foreign Office archival documents that have never been used by researchers so far in relations to Ethiopia’s claims over Djibouti, this study thoroughly examines the historical foundations of such claims. In addition to the classified diplomatic correspondence documents, attempts have been made to enrich the study with contemporary sources. According to the top-secret letter sent from the British Embassy in Addis Ababa to the Foreign Office in London in 1919, France had signed a secret agreement with Ethiopia pledging that it would hand over the former French Somaliland (now the Republic of Djibouti) to the Ethiopian government when requested by the latter. In violation of the agreement, the French government announced that the people of the territory would decide their future in a referendum in 1867. Soon afterwards, the Ethiopian government claimed that Djibouti was one of Ethiopia’s lost provinces. To the delight of the French government, the people voted for continued association with France. Despite Ethiopia’s historical rights, the new military government of Ethiopia officially declared in 1975 that it had no claims over Djibouti. In a second referendum held in 1977, the people of Djibouti voted for independence. This qualitative study thus analyzes Ethiopian’s claims over Djibouti in historical perspective.

description: This paper examines counterinsurgency (COIN) and counterterrorism mechanism-legal, legislative, administrative, and coercive strategies that have been initiated and implemented in combating violence, insurgency, and terrorism in Nigeria (2010-2022). This is with a view to highlighting the various approaches initiated and put in place to tackle the insecurity challenges that has pervaded the country arising largely from the activities of Boko Haram and other armed groups in the country. The paper relies on primary data sourced from the field work conducted in 2017 as part of PhD study and utilizesdata from the secondary sources and adopted content analysis of relevant literature. The discourse of this paper isimportant in that the issues of insecurity in Nigeria in the last decade have been worrisome considering the negative tales it portends for the country and its people. It is importantly to review the various efforts of the government at finding solution to the insecurity crises with a view to finding out their effectiveness or otherwise. The paper argues that though Nigerian government has put up various mechanisms a lot still has to be done to addressing the root causes ofinsurgency and terrorism in Nigeria. Also, issues of corruption, illicit arms, inter-agency rivalry, unprofessional attitudes of unpatriotic members of the country’s military who report said sells arms to the insurgents, issue of the porous border and issues relating to lack of funding of militaryagencies,among other are still fundamental issues militating against the counterinsurgency and counterterrorism efforts.

title: Evaluating the Level of Harmonic Distortion in a Typical Distribution Feeder
Creators: name: Bogale, Wessen S.
Publisher: name: University of Nevada, Las Vegas
Year: 2015

description: Steady-state analysis of electrical power systems is largely based on linear and sinusoidal AC circuits which allow the concept of impedance, phasors and well-defined power quantities (i.e., real, reactive and apparent powers). In reality, however, the electric load which was once composed of linear elements (e.g., induction motors, incandescent lighting, etc …) is becoming more and more nonlinear due to the wide-spread use of electronic components such as fluorescent lighting and variable-frequency drives that power the majority of electric motors. As a consequence, the current drawn by such devices is often distorted, thus containing a number of high frequency harmonics that are superimposed on the fundamental 60 Hz component. As these high-frequency harmonic currents flow through the power distribution apparatus, they in turn cause distortion in the voltage. The distorted voltage can in turn affect other loads that share a transformer or branch circuit with the original harmonic loads.
It has been shown that classical definitions of electric power; namely, active, reactive and apparent powers, do not fulfill the conditions caused by harmonics. Consequently, various power definitions and calculation methods have been proposed in the literature.
It is hypothesized that existing definitions of power other than the active part in non-sinusoidal circuits are based on a non-real (i.e., frequency) domain and rate theoretical in nature. Therefore, these are not only hard (often impossible) to interpret their physical meaning and make use of them, but also hard to implement in measuring devices. On the other hand, power definitions that are based on a real time domain are expected to have simpler physical interpretations and easier to measure. A simple definition of non-active power will be of great value to the power industry. It is also hypothesized that a typical electrical power distribution system can handle significantly more non-linear loads than previously thought as modern electrical loads are less sensitive to distortion in the voltage supply.
The motivation that led to the proposed works stems from the fast moving events that are taking place in the electric utility industry. more specifically, many utilities are considering additional customer charges (such as charging the residential sector for peak demand, reactive power consumption, and renewable power generation) in order to ring more profits. The recently installed smart meters that primarily record energy consumption every 5 minutes and communicate wirelessly the local utility, do have the ability to measure other electrical quantities. The way these quantities are defined and measured is of critical importance to both the supplier and consumer.

description: We present multiwavelength data of the blazar 3C 454.3 obtained during an extremely bright outburst from November 2010 through January 2011. These include flux density measurements with the Herschel Space Observatory at five submillimeter-wave and far-infrared bands, the Fermi Large Area Telescope at gamma-ray energies, Swift at X-ray, ultraviolet (UV), and optical frequencies, and the Submillimeter Array at 1.3 mm. From this dataset, we form a series of 52 spectral energy distributions (SEDs) spanning nearly two months that are unprecedented in time coverage and breadth of frequency. Discrete correlation anlaysis of the millimeter, far-infrared, and gamma-ray light curves show that the variations were essentially simultaneous, indicative of co-spatiality of the emission, at these wavebands. In contrast, differences in short-term fluctuations at various wavelengths imply the presence of inhomegeneities in physical conditions across the source. We locate the site of the outburst in the parsec-scale core, whose flux density as measured on 7 mm Very Long Baseline Array images increased by 70 percent during the first five weeks of the outburst. Based on these considerations and guided by the SEDs, we propose a model in which turbulent plasma crosses a conical standing shock in the parsec-scale region of the jet. Here, the high-energy emission in the model is produced by inverse Compton scattering of seed photons supplied by either nonthermal radiation from a Mach disk, thermal emission from hot dust, or (for X-rays) synchrotron radiation from plasma that crosses the standing shock. For the two dates on which we fitted the model SED to the data, the model corresponds very well to the observations at all bands except at X-ray energies, where the spectrum is flatter than observed.

“It can happen to anybody:” Identity-blind rhetoric and LGBTQ inclusion in sex education dating violence prevention
Creators: name: Rudd, Emma
Publisher: name: University of Chicago
Year: 2021
Subjects: subject: sexuality
subject: teen dating violence
subject: inclusivity
subject: sex education

description: Recent research concerning the prevalence of dating violence among U.S. adolescents indicates increased rates among LGBTQ adolescents as compared to their heterosexual and cisgender peers. While schools have worked to combat teen dating violence by including lessons on healthy relationships in sex education curricula, little is known about the effectiveness of such lessons for addressing the unique factors related to both the nature and dynamics of dating violence within the LGBTQ community. This research addresses this lack by observing how sex education teachers address and incorporate LGBTQ-related information in their lessons on healthy relationships and dating violence prevention. Adapting research on color-blind ideology, I argue that teachers employ an “identity-blind” approach to such lessons wherein discussions of power differentials and social context are dismissed in an appeal to the universality of dating violence experiences. In relying on an identity-blind approach as a means of inclusivity, teachers disregard more progressive, and possibly effective, tactics for addressing LGBTQ teen dating violence.

description: Let $H_0$, $H$ be a pair of self-adjoint operators for which the standard assumptions of the smooth version of scattering theory hold true. We give an explicit description of the absolutely continuous spectrum of the operator $\mathcal{D}_θ=θ(H)-θ(H_0)$ for piecewise continuous functions $θ$. This description involves the scattering matrix for the pair $H_0$, $H$, evaluated at the discontinuities of $θ$. We also prove that the singular continuous spectrum of $\mathcal{D}_θ$ is empty and that the eigenvalues of this operator have finite multiplicities and may accumulate only to the "thresholds" of the absolutely continuous spectrum of $\mathcal{D}_θ$. Our approach relies on the construction of "model" operators for each jump of the function $θ$. These model operators are defined as certain symmetrised Hankel operators which admit explicit spectral analysis. We develop the multichannel scattering theory for the set of model operators and the operator $θ(H)-θ(H_0)$. As a by-product of our approach, we also construct the scattering theory for general symmetrised Hankel operators with piecewise continuous symbols.
Ruelle-Perron-Frobenius operator approach to the annealed pinning model with Gaussian long-range correlated disorder
Creators: name: Poisat, Julien
Publisher: name: arXiv
Year: 2012
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: In this paper we study the pinning model with correlated Gaussian disorder. The presence of correlations makes the annealed model more involved than the usual homogeneous model, which is fully solvable. We prove however that if the disorder correlations decay fast enough then the annealed critical behaviour is the same as the homogeneous one. Our result is sharper if the decay is exponential. The approach we propose relies on the spectral properties of a transfer or Ruelle-Perron Frobenius operator related to the model. We use results on these operators that were obtained in the framework of the thermodynamic formalism for countable Markov shifts. We also provide large-temperature asymptotics of the annealed critical curve under weaker assumptions.

description: Selective coherence control and electrically mediated exchange coupling of single electron spin between triplet and singlet states using numerically derived optimal control of proton pulses is demonstrated. We obtained spatial confinement below size of the Bohr radius for proton spin chain FWHM. Precise manipulation of individual spins and polarization of electron spin states are analyzed via proton induced emission and controlled population of energy shells in pure 29Si nanocrystal. Entangled quantum states of channeled proton trajectories are mapped in transverse and angular phase space of 29Si axial channel alignment in order to avoid transversal excitations. Proton density and proton energy as impact parameter functions are characterized in single particle density matrix via discretization of diagonal and nearest off-diagonal elements. We combined high field and low densities (1 MeV/92 nm) to create inseparable quantum state by superimposing the hyperpolarizationed proton spin chain with electron spin of 29Si. Quantum discretization of density of states (DOS) was performed by the Monte Carlo simulation method using numerical solutions of proton equations of motion. Distribution of gaussian coherent states is obtained by continuous modulation of individual spin phase and amplitude. Obtained results allow precise engineering and faithful mapping of spin states. This would provide the effective quantum key distribution (QKD) and transmission of quantum information over remote distances between quantum memory centers for scalable quantum communication network. Furthermore, obtained results give insights in application of channeled protons subatomic microscopy as a complete versatile scanning-probe system capable of both quantum engineering of charged particle states and characterization of quantum states below diffraction limit linear and in-depth resolution.

description: A novel coronavirus (CoV), Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in late 2019 in Wuhan, China and has since spread as a global pandemic. Safe and effective vaccines are thus urgently needed to reduce the significant morbidity and mortality of Coronavirus Disease 2019 (COVID-19) disease and ease the major economic impact. There has been an unprecedented rapid response by vaccine developers with now over one hundred vaccine candidates in development and at least six having reached clinical trials. However, a major challenge during rapid development is to avoid safety issues both by thoughtful vaccine design and by thorough evaluation in a timely manner. A syndrome of “disease enhancement” has been reported in the past for a few viral vaccines where those immunized suffered increased severity or death when they later encountered the virus or were found to have an increased frequency of infection. Animal models allowed scientists to determine the underlying mechanism for the former in the case of Respiratory syncytial virus (RSV) vaccine and have been utilized to design and screen new RSV vaccine candidates. Because some Middle East respiratory syndrome (MERS) and SARS-CoV-1 vaccines have shown evidence of disease enhancement in some animal models, this is a particular concern for SARS-CoV-2 vaccines. To address this challenge, the Coalition for Epidemic Preparedness Innovations (CEPI) and the Brighton Collaboration (BC) Safety Platform for Emergency vACcines (SPEAC) convened a scientific working meeting on March 12 and 13, 2020 of experts in the field of vaccine immunology and coronaviruses to consider what vaccine designs could reduce safety concerns and how animal models and immunological assessments in early clinical trials can help to assess the risk. This report summarizes the evidence presented and provides considerations for safety assessment of COVID-19 vaccine candidates in accelerated vaccine development.

description: We consider the problem of existence of asymptotic observables in local relativistic theories of massive particles. Let $\ti p_1$ and $\ti p_2$ be two energy-momentum vectors of a massive particle and let $\De$ be a small neighbourhood of $\ti p_1+\ti p_2$. We construct asymptotic observables (two-particle Araki-Haag detectors), sensitive to neutral particles of energy-momenta in small neighbourhoods of $\ti p_1$ and $\ti p_2$. We show that these asymptotic observables exist, as strong limits of their approximating sequences, on all physical states from the spectral subspace of $\De$. Moreover, the linear span of the ranges of all such asymptotic observables coincides with the subspace of two-particle Haag-Ruelle scattering states with total energy-momenta in $\De$. The result holds under very general conditions which are satisfied, for example, in $\la ϕ^4_2$. The proof of convergence relies on a variant of the phase-space propagation estimate of Graf.

description: Deeply embedded and at distances of several kiloparsecs, massive young stellar objects (MYSOs) present numerous challenges for observation and study. In this work, we present spatially-resolved observations of one MYSO, AFGL 4176, together with survey and literature data, ranging from interferometric observations with VLTI/MIDI in the mid-infrared, to single-dish Herschel measurements in the far-infrared, and sub-millimeter data from APEX. We consider this spatially-resolved, multi-wavelength data set in terms of both radiative transfer and geometric models. We find that the observations are well described by one-dimensional models overall, but there are also substantial deviations from spherical symmetry at scales of tens to hundreds of astronomical units, which are revealed by the mid-infrared interferometric measurements. We use a multiple-component, geometric modeling approach to explain the mid-infrared emission on scales of tens to hundreds of astronomical units, and find the MIDI measurements are well described by a model consisting of a one-dimensional Gaussian halo and an inclined (θ=60 deg) circumstellar disk extending out to several hundred astronomical units along a position angle of 160 deg. Finally, we compare our results both with previous models of this source, and with those of other MYSOs, and discuss the present situation with mid-infrared interferometric observations of massive stars.

description: The development of the CHARMM force field (FF) in the late 1970’s and early 1980’s was groundbreaking at the time. For the first time, a computer program was created that could simulate biological systems on a macromolecular scale. Starting with the simulation of simple proteins, CHARMM has since expanded to include such macromolecules as nucleic acids and lipids, now being able to model complex biological systems and processes. Force fields like CHARMM can be represented in different ways. For example, force fields can be represented through an all-atom representation, in which all atoms in a system are modeled as distinct interaction units. This representation can be simplified into a united-atom representation, which shall be the primary focus of this thesis. A united atom FF has no explicit interaction sites for hydrogen. Instead, the hydrogens are lumped onto the atoms they are connected to, termed ‘heavy atoms’ as these atoms have a greater atomic weight than hydrogen. The CHARMM FF originally had a united-atom representation for proteins, which was abandoned to focus on all-atom representations. However, in certain cases, such as lipid tails, united-atom representations are often useful in certain situations; as compared to all-atom representations, united-atom models often speed up simulation times, which is useful in the simulation of large enough systems of molecules. Although there are currently united-atom representations for many types of biomolecules in the CHARMM FF, including multiple types of membrane lipids, there has yet to be a united-atom model for sphingolipids, a type of membrane lipid most commonly found in the myelin sheath of neurons, although its presence has been noted in many types of eukaryotic cells. The goal of this thesis is thus to develop such a model and implement it in the CHARMM FF.

description: Ethereum is a platform for deploying smart contracts, which due to their public nature and the financial value of the assets they manage are attractive targets for attacks. With asset management as a main task of smart contracts, access control aspects are naturally part of the application itself, but also of the functions implemented in a smart contract. Therefore, it is desirable to establish the correctness of smart contracts and their access control on application and single-function level through formal methods. However, there is no established methodology of formalising and verifying correctness properties of smart contracts. In this work, we make an attempt in this direction on the basis of a case study. We choose an existing smart contract application which aims to ascertain the integrity of binary files distributed over the Internet by means of decentralised identity management and access control. We formally specify and verify correctness at the level of single functions as well as temporal properties of the overall application. We demonstrate how to use verified low-level correctness properties for showing correctness at the higher level. In addition, we report on our experience with existing verification tools.

title: In Vitro Studies of Gold and Gold Silica Nanoparticle Radiosensitization with Kilovoltage X-Rays
Creators: name: Colarch, Gregory

description: Technological advances in the ability to construct and manipulate nanoscale particles have opened up the possibility of using solid metallic nanoparticles and mixed metal nanoshells as a means to increase dose enhancement and treatment efficacy to tumors. In order for nanoparticles to be an effective form of treatment, they must be delivered to tumors in sufficient concentrations so that there is a dose enhancement factor due to ionizing radiation, as well as being essentially non-toxic to healthy cells. Gold nanoparticles and silica-gold nanoshells fit these requirements. Gold has a high atomic number (Z=79), which gives a larger cross section for the photoelectric effect vs. tissue with regards to kilovoltage x-rays. Both gold and silica are also relatively inert and biocompatible.
The investigation of dose enhancement to cells that have been incubated with nanoparticles and nanoshells is the focus of this thesis. The effectiveness of the treatment was determined by measuring the size of multicellular hybrid spheroids consisting of human glioma cells and murine lymphocytic monocytes. Dose enhancement effects was also examined in murine lymphocytic monocytes using an MTS assay, which measures metabolic activity in cells.
A clear dose response was observed for spheroids consisting of human glioma cells only: increasing doses resulted in decreased spheroid growth. With a few exceptions, this trend was also observed in hybrid spheroids consisting of glioma cells and nanoparticle or nanoshell loaded monocytes. Contrary to the premise of utilizing the photoelectric effect, the most pronounced dose effect was observed in the pure glioma irradiated spheroids which showed greater growth suppression compared to the nanoparticle and nanoshell loaded hybrid spheroids at each dose investigated. A similar trend was found when comparing the viability of bare and nanoparticle/nanoshell loaded monocytes exposed to kilovoltage x-rays. These results are considered anomalous since kilovoltage x-rays are expected to be more damaging to cells and spheroids containing nanoparticles/nanoshells due to enhanced photoelectric absorption. The anomalous results were attributed to inaccuracies in x-ray tube output.
Optimization of MTS parameters required for accurate determination of monocyte viability represents the most significant finding of this work. It was found that 50,000 cells per well yielded an accurate MTS signal. Furthermore, the MTS assay should not be performed less than 96 hours from the time of irradiation. As long as this 96 hour criterion is satisfied, any of the investigated MTS incubation times (1 – 4 hours) can be used. Finally, at the concentrations used in these studies, neither nanoparticles nor nanoshells were toxic to murine lymphocytes.

description: The progenitors of many Type II supernovae have been observationally identified but the search for Type Ibc supernova (SN Ibc) progenitors has thus far been unsuccessful, despite the expectation that they are luminous Wolf-Rayet (WR) stars. We investigate how the evolution of massive helium stars affects their visual appearances, and discuss the implications for the detectability of SN Ibc progenitors. Massive WR stars that rapidly lose their helium envelopes through stellar-wind mass-loss end their lives when their effective temperatures -- related to their hydrostatic surfaces -- exceed about 150kK.At their pre-supernova stage, their surface properties resemble those of hot Galactic WR stars of WO sub-type. These are visually faint with narrow-band visual magnitudes Mv = -1.5 ~ -2.5, despite their high bolometric luminosities (log L/Lsun = 5.6 ~ 5.7), compared to the bulk of Galactic WR stars (Mv < -4). In contrast, relatively low-mass helium stars that retain a thick helium envelope appear fairly bright in optical bands, depending on the final masses and the history of the envelope expansion during the late evolutionary stages. We conclude that SNe Ibc observations have so far not provided strong constraints on progenitor bolometric luminosities and masses, even with the deepest searches. We also argue that Ic progenitors are more challenging to identify than Ib progenitors in any optical images.

Can A Relationship Optimism and Perfectionism Intervention Increase Romantic Relationship Well-being?

description: A key predictor for romantic relationship quality is relationship optimism (also known as positive relationship expectations). However, relationship expectations can negatively affect relationship well-being when they become unrealistic and rigid, also known as dyadic perfectionism. The current research tests the effectiveness of a novel intervention that aims to improve relationship optimism and decrease dyadic perfectionism among couples. The four components of the intervention were based on previously validated social-psychological interventions that target relevant traits such as personal optimism and growth mindset. There were three intervention conditions. The first condition paired relationship optimism and dyadic perfectionism components together. The second condition only had the relationship optimism component. The third was the control condition. Results showed that despite a significant effect of the intervention on lowering immediate dyadic perfectionism, the intervention failed to have enduring effects on relationship optimism or dyadic perfectionism. Additionally, this intervention did not improve relationship quality on other indicators. Implications, broader impacts, and future directions based on the current results are discussed.

description: A correlation between lattice parameters, oxygen composition, and the thermoelectric and Hall coefficients is presented for single-crystal Li(0.9)Mo(6)O(17), a quasi-one-dimensional (Q1D) metallic compound. The possibility that this compound is a compensated metal is discussed in light of a substantial variability observed in the literature for these transport coefficients.

description: Non-white and gender and sexual minority (GSM) individuals experience minority stress through stigmatization and marginalization which can lead to higher rates of mental health issues, and limited access to healthcare. Using an intersectionality framework, these mental health issues are compounded for individuals with both GSM and non-white identities. Within the incarceration setting, mental health issues may be exacerbated due to the pains of imprisonment which can lead to frustration and psychological distress, along with differentially adverse experiences for GSM and non-white individuals. This study examines mental health symptoms, diagnoses, and use of care for GSM, non-white, and the intersection of GSM and non-white individuals in correctional facilities using the 2016 Survey of Prison Inmates (N=24,234). In nearly all the analyses GSM individuals and GSM non-white individuals had higher rates of mental health symptoms, diagnoses, and care, and non-white individuals had significantly lower rates of mental health symptoms, diagnoses, and use of care. This may indicate that GSM individuals continue to experience pains of imprisonment despite higher use of mental health care, and that there may be a need for GSM-specific mental health care. Non-white individuals may have lower rates of symptoms and diagnoses due to White-centric frames of evaluation and fear of approaching providers for needed healthcare. It may be useful to develop culturally sensitive evaluation criteria for non-white individuals. This study is the first of its kind to look at mental health symptoms of GSM individuals in prison in a nationally representative sample.
