Creators: name: Yitbarek, Tigist
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Background: Malaria diagnosis by microscopy is the gold standard method for confirming the cases. In spite of clinical diagnosis, the inability of laboratory professionals on microscopy diagnosis has led to over as well as under diagnosis. This may result in inappropriate use of anti-malarial drugs that increases the risk of drug resistance, and other diseases are overlooked and not treated in a timely manner. Objective: To evaluate the performance of laboratory professionals in diagnosis of malaria species among selected health facilities found under Defense Health Main Department in Addis Ababa and surrounding area, Ethiopia. Method: A cross sectional study was conducted from June to July, 2015. All laboratory professionals who work in selected health facilities were included in the study. Data was collected by distributing a standardized pre-validated malaria slide panel and self-administered questionnaires. Finally, data analysis was performed using SPSS version 20 to look an association between independent variable and dependent variable. An agreement in detection and species identification of malaria parasites between participants and expert microscopists was estimated using the Kappa score. Result: The mean age of the participants was 32 ± 5.43 years. The majority of the participants 48 (80%) were males. Only 9(15%) participants used recommended quantification system. Five(8.3%) of the participants correctly reported all the distributed slides, whereas 55(91.7%) missed at least two slide. Overall, the sensitivity and specificity of performance among participants in detection of malaria parasites were 65.7% and 100% respectively. The overall agreement in performance between participants and reference readers on detection of malaria parasite was 71.4% (Kappa = 0.4) while on identification of malaria species, it was 51.1% (kappa = 0.04). Lower agreement was observed on detection and identification of slides with low parasitic density and mixed infection. Conclusion: Agreement of performance among the participants and expert microscopist in the detection of malaria parasites was better than agreement in the identification of different species of malaria. Poor agreement was reported in detection of parasites at a low density and mixed infections. Hence, malaria control program should work towards increasing the competency of lab personnel in malaria microscopy, particularly in non-malarious area of the country where the professionals have lower exposure to malaria diagnosis.

description: In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the $QQ\bar{Q}\bar{q}$ tetraquark states and estimated their rough masses in this work. These systems include the explicitly exotic states $cc\bar{b}\bar{q}$ and $bb\bar{c}\bar{q}$ and the hidden exotic states $cc\bar{c}\bar{q}$, $cb\bar{b}\bar{q}$, $bc\bar{c}\bar{q}$, and $bb\bar{b}\bar{q}$. If a state around the estimated mass region could be observed, its nature as a genuine tetraquark is favored. The strong decay patterns shown here will be helpful to the experimental search for these exotic states.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Vitamin D deficiency causes rickets in children, and osteomalacia in children and adults. In 2016 musculoskeletal conditions are second cause of disability worldwide. Vitamin D deficiency and insufficiency can be both corrected and prevented safely through supplementation therapy. Therefore assessing prevalence of vitamin D deficiency and associated risk factors among patients with nonspecific musculoskeletal pain symptoms is crucial in Ethiopian context. Objective: To determine the prevalence of vitamin D deficiency and its associated risk factors in patients with nonspecific musculoskeletal pain symptoms in Tikure Anbessa Specialized Hospital (TASH), Addis Ababa ; Ethiopia. Methods: A cross-sectional study was conducted among patients with nonspecific musculoskeletal pain symptoms from March to May 2018 at TASH. Demographic data were collected using a structured questionnaire. Clinical data were obtained from medical records. Anthropometric indices were measured. Alkaline phosphatase (ALP) was determined in TASH laboratory with Mindray-200E. Vitamin D was determined with Mini Vidas hormone analyzer in Ras Desta Memorial hospital laboratory. Calcium (Ca) and Phosphorous (P) were analyzed in EPHI laboratory with Cobas 6000 c501 module. The data were entered into SPSS version 20 for analysis. Results: Among the total 75 study participants with nonspecific musculoskeletal pain symptoms, 66 (88%) had vitamin D deficiency and 9 (12%) had vitamin D insufficient. Age, body mass index (BMI), waist circumference (WC) and occupation were associated with vitamin D deficiency. However, ALP, Ca, and P levels were not significantly correlated with vitamin D level. BMI were identified as independent risk factors for vitamin D deficiency. Conclusion: The prevalence of vitamin D deficiency was high among patients with nonspecific musculoskeletal pain symptoms in this tertiary care. Obesity was independent risk factors for vitamin D deficiency.

description: Background: The use of ARV prophylaxis during pregnancy can dramatically reduce the risk of vertical transmission of HIV infection. Currently, limited studies have documented the effect of ART in decreasing the risk of opportunistic infection as well as improving survival of HIV infected pregnant women and fetus. However, little is known about its impact on hematological parameters in resource limited settings like Ethiopia. Objective: To assess changes in hematological parameters after 6 months of ART initiation among HIV infected pregnant and non-pregnant women at Zewditu Memorial Hospital ART clinic, Addis Ababa, Ethiopia. Methodology: A retrospective comparative study was conducted among HIV infected pregnant women who received ART between September 2008 and January 2014 at ART clinic of Zewditu Memorial Hospital, Addis Ababa, Ethiopia. Data conveniently collected from 384 pregnant women on ART was compared with that obtained from 384 non pregnant women who are on ART as controls. Demographic, clinical and hematological parameters data were collected between November and December 2016 carefully from the existing ART logbook and antenatal follow up cards. Data collected through a standardized format were entered into Excel spread sheet and transported into and analyzed by SPSS Version 20 software. Dependent variable frequencies, mean, standard deviation and range were calculated. Mean change of different hematological values during follow up time from the base line were compared using paired t-test. P value <0.05 was considered as statistically significant. Results: The results of the study indicated significant difference in RBC Count, Hb, HCT, MCV, MCH,MCHC PLT counts were statistically significantly lower, while CD4 count was significantly higher in HIV infected pregnant women compared to non pregnant women. There was no statistically significant difference between the two groups for PLT and total WBC. Prevalence of anemia, leucopenia, thrombocytopenia and CD4+ T lyphocytopenia at baseline and 6 months of follow up were 49.5% vs 54.4%, 20.7% vs 4.9% , 20.8% vs 18.8% and 88.8% vs 69.8% for HIV infected pregnant women, respectively. The respective values in HIV infected non pregnant women were 37% vs 18% , 8.6% vs 5.8% ,38% vs 7.8% and 58.6% vs 34.1.Microcytic hypochromic anemia was the dominant type in the pregnant women while normocytic hypochromic was the commonest followed by microcytic hypochromic anemia in the non-pregnant women. Thus, monitoring of all hematological parameters (not only Hb) is warranted. Conclusion: Comparison of hematological parameters of HIV infected pregnant with non pregnant significant changes. Since these parameters are strongly influenced as a result of pregnancy. Key words: Pregnant women, Hematological parameters, anemia, thrombocytopenia, CD4+ T cells and ART

description: We study the Ising Hamiltonian with a transverse field term to simulate the quantum annealing. Using shortcuts to adiabaticity, we design the time dependence of the Hamiltonian. The dynamical invariant is obtained by the mean-field ansatz, and the Hamiltonian is designed by the inverse engineering. We show that the time dependence of physical quantities such as the magnetization is independent of the speed of the Hamiltonian variation in the infinite-range model. We also show that rotating transverse magnetic fields are useful to achieve the ideal time evolution.

description: The coupled dynamics of low lying modes and various giant resonances are studied with the help of the Wigner Function Moments method generalized to take into account spin degrees of freedom and pair correlations simultaneously. The method is based on Time Dependent Hartree-Fock-Bogoliubov equations. The model of the harmonic oscillator including spin-orbit potential plus quadrupole-quadrupole and spin-spin interactions is considered. New low lying spin dependent modes are analyzed. Special attention is paid to the scissors modes. A new source of nuclear magnetism, connected with counter-rotation of spins up and down around the symmetry axis (hidden angular momenta), is discovered. Its inclusion into the theory allows one to improve substantially the agreement with experimental data in the description of energies and transition probabilities of scissors modes.

description: Tensor contractions constitute a key computational ingredient of numerical multi-linear algebra. However, as the order and dimension of tensors grow, the time and space complexities of tensor-based computations grow quickly. Existing approaches for tensor contractions typically involves explicit copy and transpose operations. In this paper, we propose and evaluate a new BLAS-like primitive STRIDEDBATCHEDGEMM that is capable of performing a wide range of tensor contractions on CPU and GPU efficiently. Through systematic benchmarking, we demonstrate the advantages of our approach over conventional approaches. Concretely, we implement the Tucker decomposition and show that using our kernels yields 100x speedup as compared to the implementation using existing state-of-the-art libraries.

description: Hybrid quantum systems can often be described in terms of polaritons. These are quasiparticles formed of superpositions of their constituents, with relative weights depending on some control parameter in their interaction. In many cases, these constituents are coupled to reservoirs at different temperatures. This suggests a general approach to the realization of polaritonic heat engines where a thermodynamic cycle is realized by tuning this control parameter. Here we discuss what is arguably the simplest such engine, a single qubit coupled to a single photon. We show that this system can extract work from feeble thermal microwave fields. We also propose a quantum measurement scheme of the work and evaluate its back-action on the operation of the engine.

description: This dissertation discusses how big data platforms like RetailNext used their power to help retailers fight through the COVID-19 pandemic crisis. It discusses the analytics retailers had at their disposal and how they utilized them to gain insights into the pandemic, shoppers' behavioral changes, and lockdowns. They pivoted from traditional retailers to restrictive experience centers and complied with the authorities' new regulations to combat the COVID-19 virus. It discusses various methods of retail analytics platforms used to help retailers plan, organize, and forecast operations strategies. It also discusses what tools and strategies worked well, their findings, and learned lessons, and suggests the changes that must be incorporated permanently into the retail businesses. Moreover, it discusses how COVID-19 impacted consumers and their shopping behaviors, how they have shifted towards their online shopping, and what habits they have adopted that will last after the pandemic has ended.

description: Geoengineering is a discipline that aims to alter the climate to mitigate climate change impacts. Solar Radiation Management (SRM) plans to achieve this by reducing the amount of solar radiation absorbed within the Earth. Here, we evaluate SRM frameworks in an attempt to mitigate surface temperature and precipitation changes arising from increased atmospheric CO2. In chapter 1, we achieve the desired outcome by using an optimised SRM implementation. In chapter 2, we find increased precipitation reduction in experiments forced with quadrupled CO2 rather than increased solar radiation. Finally, in chapter 3, we reduce rainfall change by applying atmospheric heat fluxes.

description: We present an analytic formula for the galaxy bispectrum in redshift space on the basis of the halo approach description with the halo occupation distribution of central galaxies and satellite galaxies. This work is an extension of a previous work on the galaxy power spectrum, which illuminated the significant contribution of satellite galaxies to the higher multipole spectrum through the non-linear redshift space distortions of their random motions. Behaviors of the multipoles of the bispectrum are compared with results of numerical simulations assuming a halo occupation distribution of the LOWZ sample of the SDSS-III BOSS survey. Also presented are analytic approximate formulas for the multipoles of the bispectrum, which is useful to understanding their characteristic properties. We demonstrate that the Fingers of God effect is quite important for the higher multipoles of the bispectrum in redshift space, depending on the halo occupation distribution parameters.

Second-Order Switching Time Optimization for Switched Dynamical Systems

description: Switching time optimization arises in finite-horizon optimal control for switched systems where, given a sequence of continuous dynamics, one minimizes a cost function with respect to the switching times. We propose an efficient method for computing the optimal switching times for switched linear and nonlinear systems. A novel second-order optimization algorithm is introduced where, at each iteration, the dynamics are linearized over an underlying time grid to compute the cost function, the gradient and the Hessian efficiently. With the proposed method, the most expensive operations at each iteration are shared between the cost function and its derivatives, thereby greatly reducing the computational burden. We implemented the algorithm in the Julia package SwitchTimeOpt allowing the user to easily solve switching time optimization problems. In the case of linear dynamics, many operations can be further simplified and benchmarks show that our approach is able to provide optimal solutions in just a few ms. In the case of nonlinear dynamics, two examples show that our method provides optimal solutions with up to two orders of magnitude time reductions over state-of-the-art approaches.

description: The strongest transitions of Zn and CrII are the most sensitive to relative variations in the fine-structure constant ($Δα/α$) among the transitions commonly observed in quasar absorption spectra. They also lie within just 40Å of each other (rest frame), so they are resistant to the main systematic error affecting most previous measurements of $Δα/α$: long-range distortions of the wavelength calibration. While Zn and CrII absorption is normally very weak in quasar spectra, we obtained high signal-to-noise, high-resolution echelle spectra from the Keck and Very Large Telescopes of 9 rare systems where it is strong enough to constrain $Δα/α$ from these species alone. These provide 12 independent measurements (3 quasars were observed with both telescopes) at redshifts 1.0--2.4, 11 of which pass stringent reliability criteria. These 11 are all consistent with $Δα/α=0$ within their individual uncertainties of 3.5--13 parts per million (ppm), with a weighted mean $Δα/α= 1.2\pm1.7_{\rm stat}\pm0.9_{\rm sys}$ ppm (1$σ$ statistical and systematic uncertainties), indicating no significant cosmological variations in $α$. This is the first statistical sample of absorbers that is resistant to long-range calibration distortions (at the $

description: By cross-correlating both the Parkes Catalogue and the Second Planck Catalogue of Compact Sources with the arrival direction of the track-type neutrinos detected by the IceCube Neutrino Observatory, we find the flat-spectrum blazar PKS 0723-008 as a good candidate for the high-energy neutrino event 5 (ID5). Apart from its coordinates matching those of ID5, PKS 0723-008 exhibits further interesting radio properties. Its spectrum is flat up to high Planck frequencies, and it produced a fivefold-increased radio flux density through the last decade. Based upon these radio properties we propose a scenario of binary black hole evolution leading to the observed high-energy neutrino emission. The main contributing events are the spin-flip of the dominant black hole, the formation of a new jet with significant particle acceleration and interaction with the surrounding material, with the corresponding increased radio flux. Doppler boosting from the underlying jet pointing to the Earth makes it possible to identify the origin of the neutrinos, so the merger itself is the form of an extended flat-spectrum radio emission, a key selection criterion to find traces of this complex process.

Association of Intestinal Helminthic Infection, Atopy and Allergic Disorder in the Setting of Mass Deworming Among Selected Government Primary School Children in Sululta Woreda, Oromia, Ethiopia
Creators: name: Abera, Dessie
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Intestinal helminthic infections have been suggested to play protective role from allergic sensitization and atopic diseases. There is a concern that deworming could increase the prevalence of atopic disease in endemic populations. There is inconsistent and little information about the relationship between helminthic infection and allergic disease in Ethiopia. Objective: The aim of this study was to assess the association of intestinal helminthes and atopy /allergic disorder in the setting of mass deworming among school children in Sululta, Oromia, Ethiopia. Methods: A cross sectional study was conducted among 526 school children aged 5 to 14 years from three selected government primary schools in Sululta woreda. Information on socio-demographic characteristic, associated risk factors and allergic symptoms were obtained using questionnaire. From all children, fresh stool samples were collected and processed by direct wet mount, formol-ether concentration and Kato-Katz technique and atopy was assessed by skin prick test (SPT). In addition, venous blood was collected for eosinophil count. Data was entered and analyzed using SPSS version21 statistical software. The odds ratio and 95% confidence interval was calculated to assess the strength of the association. P-value less than 0.05 were considered as statistically significant. Results: Of the total 526 school children 58.2% (306) were females. Overall 24% (n=126/526) had questionnaire based allergic symptoms while 5.1 % (n=27/526) had skin prick test reactivity, 16.9% of them (n=89/526) had intestinal helminthic infection. All helminthic infections were with low intensity level. There was no association between helminthic infection and allergic symptoms (OR=1.30, 95% CI=0.778-2.171, P=0.317). Ascaris lumbricoides infection was positively associated with skin test reactivity (AOR=4.307, 95%CI=1.143-16.222, P=0.031). Atopy was significantly associated with increased allergy symptoms (AOR=2.787, 95%CI=1.253-6.197, P=0.012). Short term deworming had no effect on atopy but has a protective effect on allergic symptom. Conclusion: Low intensity and low prevalence of helminthic infection in our findings may have contributed to the non-significant association of allergy and helminthes infection; however, Ascaris lumbricoides was positively associated with atopy. Further longitudinal study is recommended to examine the mechanism of Ascaris lumbricoides infection for the development of atopy. Keywords: Atopy, Allergy, Intestinal helminthes, School children

description: In this paper we consider a generally covariant theory of gravity, and extend the generalized off-shell ADT current such that it becomes conserved for field dependent (asymptotically) Killing vector field. Then we define the extended off-shell ADT current and the extended off-shell ADT charge. Consequently, we define the conserved charge perturbation by integrating from the extended off-shell ADT charge over a spacelike codimension two surface. Eventually, we use the presented formalism to find the conserved charge perturbation of an asymptotically flat spacetime. The conserved charge perturbation we obtain is exactly matched with the result of the paper \cite{6'}. These charges are as representations of the $BMS_4$ symmetry algebra. Also, we find that the near horizon conserved charges of a non-extremal black hole with extended symmetries are the Noether charges. For this case our result is also exactly matched with that of the paper \cite{15}.

Publisher: name: University of Kent

description: Membrane processes have great potential in biotechnology. This study was an attempt to investigate ways in which greater novelty could be achieved. One of the advantages of ultrafiltration for the separation of proteins is the comparatively mild conditions used. Various parameters were considered when operating a crossflow filtration system containing polysulphide membranes. A key operational parameter in such a system is the temperature utilised for the process. There are conflicting demands when selecting an operating temperature between the fluid dynamics and the biochemical properties of the system. An analysis of this conflict, in order to establish the optimal temperature, involved a model crossflow filtration system, where shear rate, volume of protein containing solution and protein concentration can be kept constant and only the temperature varied. In such studies denaturation of the permeate was observed and an optimal operating temperature was observed between 30 and 40 °C. A supported liquid membrane system was investigated for the carrier mediated transport of phenylalanine to more fully understand the contradictory effects, described in the literature, of chloride ion concentration in the aqueous phases on the stability of the system. Various parameters were considered to optimise transport and stability. The role of the organic phase and its interaction with carrier and support material was also considered. The carrier mediated transport was comparable to an enzyme mediated process. Kinetic studies were undertaken and the data interpreted in a manner appropriate to biological transport processes to consider the transport process at a molecular level. The system was shown to deviate from a direct 1 : 1 exchange process between phenylalanine and chloride and had a high degree of selectivity with respect to phenylalanine.

description: Background: Chicken egg is considered as a nutritionally complete food and an excellent source of protein. While highly nutritious, eggs are also one of the leading causes of food poisoning and food borne illness in the world. In poultry industries antibiotics are used as a method of preventing, growth promoters and treating illness within the flocks. This contributes to the development of bacterial resistance to antibiotics. Objective: To assess the occurrence and antimicrobial resistance pattern of Salmonella spp., Staphylococcus aureus and Escherichia Coli O157:H7 from chicken eggs in Addis Ketema sub city, Addis Ababa, Ethiopia. Methods: A total of 380 eggs (76 composite sample) were collected from small scale producers and retail markets in the study area over a period of 6-month. The eggs were screened for Salmonella spp., S. aureus and E. coli O157:H7 following standard procedures. Isolated bacteria were subjected to antimicrobial susceptibility test. Frequencies were used to assess the magnitude of microorganisms on shells and in egg contents. Independent and dependent variables were associated by kruskal Wallis tests using SPSS version 23. Results: About 14(9.2 %), 9(5.9 %) and 18(11.8 %) of the 76 composite samples were positive for Salmonella spp., S. aureus and E. coli O157:H7 respectively. The shells showed significantly higher (p<0.05) level of contaminations than the contents for both Salmonella spp. and E. coli O157:H7 microorganisms. On the other hand, S. aureus highly contaminant on shell than content eggs even statically not significant. Salmonella spp. showed the highest resistance patterns against ampicillin (64.3 %), cefoxitin (35.7 %) and ciprofloxacin (35.7 %). E. coli O157:H7 showed highest resistance against ampicillin (72.3 %), followed by cefoxitin (55.7 %) and tetracycline (27.8 %). In case of S. aureus, the greatest number of isolates showed resistance to tetracycline (100 %) oxacillin (88.9 %), penicillin (77.8 %), erythromycin (44.4 %) and clindamycin (44.4 %). Conclusion: From the result of the study, the eggs marketed for human consumption in Addis ketema sub city, Addis Ababa is contaminated with Salmonella spp., S. aureus and E. coli O157:H7 resistance to antimicrobial agents commonly used in veterinary and human practice. Therefore, the egg should be taken with caution and the public should be educated on the dangers associated with consumption of raw and under cooked eggs and egg products.

Liberation and Consternation: Female Employment, Marriage, and Family in East Germany and Poland, 1949-1989

description: This study of female employment and family choices in Poland and East and West Germany from 1945 until 1989 seeks to make sense of the consequences of the communist half-century for the family and economic structures of eastern Europe. Taking issue with a simple dichotomization of liberal market versus socialist economies, this paper responds to claims that socialism was liberatory for women with contemporary data. Drawing on World Bank data and Malgorzata Fidelis’s study of postwar female labor in Poland, this paper examines the trajectory of standard indicators of gender equality and family structure and found no straightforward relationship between fertility, female employment, and histories of state socialism or liberal market economy. The changing conditions of postwar East Germany and Poland, as well as the economic shocks of the early 1990s, caused conditions that both impeded women’s ability to determine their own labor dynamics and provided new ways for female laborers to be active agents in determining their role and identity in newly organized societies. “Liberation” for women who worked and lived in postwar Central and Eastern Europe is not something so easily defined or measured. This study shows the subtle ways policy can shape family lives and render the line between emancipation and marginalization astonishingly thin.

description: We introduce and analyze theoretically a procedure that combines slow adiabatic STIRAP manipulation with short nonadiabatic Rabi pulses to produce any desired three-level state in a qutrit system. In this protocol, the fast pulses create superpositions between the ground state and the first excited state, while the slow pulses transfer an arbitrary population to the second excited state via stimulated Raman adiabatic passage (STIRAP). We demonstrate high-fidelity quantum control of the level populations and phases and we characterize the errors incurred under the breakdown of adiabaticity. In a configuration where an ancillary state is available, we show how to realize a nondemolition monitoring of the relative phases. These methods are general and can be implemented on any experimental platform where a quantum system with at least three accessible energy levels is available. We discuss here in detail experimental implementations in circuit quantum electrodynamics (QED) based on the results obtained with a transmon, where the control of population using the hybrid Rabi-STIRAP sequence has been achieved.

description: Planet migration is inherently a three-dimensional (3D) problem, because Earth-size planetary cores are deeply embedded in protoplanetary disks. Simulations of these 3D disks remain challenging due to the steep requirement in resolution. Using two different hydrodynamics code, FARGO3D and PEnGUIn, we simulate disk-planet interaction for a 1 to 5 Earth-mass planet embedded in an isentropic disk. We measure the torque on the planet and ensure that the measurements are converged both in resolution and between the two codes. We find that the torque is independent of the smoothing length of the planet's potential ($r_{\rm s}$), and that it has a weak dependence on the adiabatic index of the gaseous disk ($γ$). The torque values correspond to an inward migration rate qualitatively similar to previous linear calculations. We perform additional simulations with explicit radiative transfer using FARGOCA, and again find agreement between 3D simulations and existing torque formulae. We also present the flow pattern around the planets, and show that active flow is present within the planet's Hill sphere, and meridional vortices are shed downstream. The vertical flow speed near the planet is faster for a smaller $r_{\rm s}$ or $γ$, up to supersonic speeds for the smallest $r_{\rm s}$ and $γ$ in our study.

description: We study Higgs boson production in association with a top quark and a $W$ boson at the LHC. At NLO in QCD, $tWH$ interferes with $t\bar t H$ and a procedure to meaningfully separate the two processes needs to be employed. In order to define $tWH$ production for both total rates and differential distributions, we consider the diagram removal and diagram subtraction techniques that have been previously proposed for treating intermediate resonances at NLO, in particular in the context of $tW$ production. These techniques feature approximations that need to be carefully taken into account when theoretical predictions are compared to experimental measurements. To this aim, we first critically revisit the $tW$ process, for which an extensive literature exists and where an analogous interference with $t \bar t$ production takes place. We then provide robust results for total and differential cross sections for $tW$ and $tWH$ at 13 TeV, also matching short-distance events to a parton shower. We formulate a reliable prescription to estimate the theoretical uncertainties, including those associated to the very definition of the process at NLO. Finally, we study the sensitivity to a non-Standard-Model relative phase between the Higgs couplings to the top quark and to the $W$ boson in $tWH$ production.

ChatGPT made a summary of the Cosmic Influx Theory (CIT)
Creators: name: Loeffen, Ruud
Publisher: name: Zenodo
Year: 2024

description: This paper presents a summary of the Cosmic Influx Theory (CIT), which has been thoughtfully compiled in collaboration with ChatGPT. This document provides an overview of the key concepts and insights that underpin CIT, a framework that reinterprets the forces and phenomena governing our universe.

CIT challenges traditional cosmological models by proposing that the universe's expansion is directly linked to an increase in mass-energy, driven by the Root Mean Square (VRMS) velocity of celestial bodies. The theory integrates gravitational forces, cosmic expansion, and mass-energy transformations to offer a comprehensive explanation for a wide range of astronomical and geological phenomena, from the expansion of planetary orbits to dynamic tectonic activities.

I’m sharing this summary because the full theory is detailed across three key articles and supported by extensive calculations in Excel. This summary provides a concise entry point to the theory, highlighting its most critical aspects and offering many links to the more in-depth materials.
Learning Heuristics for Combinatorial Optimization Problems with Deep Neural Networks

Subjects: subject: 330

description: Solving real-world combinatorial optimization problems with traditional operations research methods can be a costly and time-consuming endeavor, often requiring the development of completely new methods or significant modification of exist- ing techniques. This has led many organizations to forego the use of analytical decision-making tools, as the costs associated with these methods can outweigh the potential savings. In this thesis, we investigate the use of machine learning techniques, especially deep reinforcement learning methods, to automate the design of problem-specific solution approaches for combinatorial optimization problems. Instead of focusing on approaches that learn to generate solutions end-to-end, we ex- amine the use of machine learning to learn heuristics for extensive search procedures. Specifically, we investigate the use of deep neural networks to learn problem-specific, heuristic components that can be incorporated into high-level, problem-agnostic search methods. By automating the design of the problem-specific components, the overall solution approach can be easily tailored to the characteristics of the problem instances at hand and make the use of optimization technologies more accessible to a wider range of organizations.
 In this thesis, we develop four novel approaches that leverage deep learning techniques to solve combinatorial optimization problems. The first approach is a tree search approach for the container pre-marshalling problem, in which deep neural networks are used to make branching and bounding decisions. The second approach is a large neighborhood search metaheuristic for routing problems that learns the repair operator using deep reinforcement learning. The third approach uses a conditional variational autoencoder to learn a mapping from discrete routing problem solutions to a continuous space that can be searched using any continuous optimization method. The fourth approach presents a simple technique for extending existing learning-based construction heuristics by an extensive and efficient search mechanism. We evaluate the performance of the proposed approaches on a variety of combinatorial optimization problems. The results suggest that machine learning techniques can be used to automate the design of problem-specific components of heuristic search methods, potentially lowering the barriers to entry for the use of optimization technologies in a wide range of novel use cases.
