description: Gestational diabetes mellitus is a growing global health problem. Inadequate management during pregnancy can lead to maternal and foetal complications. Currently, mobile health (mHealth) delivers healthcare services, playing an increasingly important role in the management of blood glucose in GDM. This study aimed to systematically evaluate the effectiveness of mHealth intervention in pregnant women with GDM. Based on randomised controlled trials of mHealth application in GDM patients searched from the database, literature screening, data extraction, and quality evaluation were conducted independently by two researchers. Statistical analysis was performed using Review Manager 5.4 software. The review included 27 studies with a total of 3483 patients. The results showed a significant improvement in glycemic control. In addition, mHealth interventions could reduce the occurrence of adverse pregnancy outcomes and improve self-management ability. In a subgroup analysis, recording of delivery mode and WeChat combined phone call indicated significant differences with mHealth interventions. It was suggested that mHealth interventions imposed a positive effect on glycemic control and reduction of adverse pregnancy outcomes in GDM patients. Our results demonstrated that the application of mHealth interventions can act as an effective and feasible approach to self-management to promote the self-management level and awareness of GDM patients.
Southern Yukon beadwork objects : a narrative of reclaiming culture
Creators: name: Johnson, Ingrid
Publisher: name: University of British Columbia
Year: 2009

description: This thesis concerns the process and outcomes of my research involving a group of Southern Yukon beadwork objects, a project carried out on behalf of the MacBride Museum in Whitehorse, Yukon, in 1993. I studied the objects themselves, researched museum documentation of them, and subsequently interviewed several women elders/beadworkers. In the thesis I examine several ways of studying and researching material culture and provide an analysis of these methods. Looking at objects in different ways tells us something about the nature of them but raises new questions which I address here. Reviewing museum collections records tells us more about the institution and the institutional lives of the objects than about their original context and meaning. Asking elders about the objects inspires them to speak about many seemingly unconnected topics: history, personal and mythical stories, and long ago life and times. An underlying theme which emerged in interviews with elders was their commentary on cultural and societal change within the First Nations community and how this has affected the process of learning for younger generations. I argue that beadwork objects can be best understood as learning and teaching tools for First Nations people of every generation, that their creation and essence are linked to every aspect of the culture, and their reclamation cannot properly happen without observance of all of these connections.
Keepers of West-African Humanism and Healing: African -Centered Storytelling Praxis by Age in Chicago

description: My dissertation explores the interdependent connection between African oral tradition and traditional African healing strategies found in storytelling in Chicago. In examining a nonprofit based in Chicago that offers cultural education through political resistance oral narratives (i.e. storytelling), my research examines how storytelling can provide emotional and cultural edification for youth and older adults that experience mental, intellectual, spiritual and racial subjugation. My work builds on the work of George J. Sefa Dei, Kmt G. Shockley, Kofi Lomotey, Lifongo Vetinde, and Jean-Blaise Samou, in that it centers African cultural production and knowledge as the source and connection to African spiritualism, communalism, and humanism and thus African traditional healing. Lastly, it presents a structured framework for an African-centered storytelling praxis as a way towards re-Africanization and healing.

description: Mixing, ignition and combustion behavior in a rapid compression and expansion machine operated under Premixed Charge Compression Ignition (PCCI) relevant conditions are investigated by combined passive optical and laser-optical high-speed diagnostics. The PCCI concept is realized using a split injection schedule consisting of a long base load injection and two closely separated short injections near top dead center. Previous studies of close-coupled double injections under constant ambient conditions showed an increased penetration rate of the subsequent fuel spray. However, the aerodynamic gain from the preceding injection is counteracted by the density rise during the compression stroke under transient engine conditions. The study confirms that the rate of mixing of the subsequent fuel spray is significantly increased. Regarding combustion behavior, the thermodynamic analysis exhibits contributions of low temperature oxidation reactions of more than 20 % to the total heat release, with a notable amount of unburnt fuel mass varying from 25 to 61 %. The analysis of the optical data reveals the multi-dimensional impact of changes in operating parameters on the local mixture field and ignition dynamics. The onset of low temperature reactivity of the first short injection is found to be dominated by the operating strategy, while the location is strongly related to the local mixing state. Low temperature ignition of the consecutive fuel spray is significantly promoted, when upstream low temperature reactivity of the preceding injection is sustained. Likewise, it is shown that high temperature ignition is accelerated by the entrainment of persistent upstream low temperature reactivity.

description: The development in the field of autonomous driving goes hand in hand with ever new developments in the field of image processing and machine learning methods. In order to fully exploit the advantages of deep learning, it is necessary to have sufficient labeled training data available. This is especially not the case for omnidirectional fisheye cameras. As a solution, we propose in this paper to use synthetic training data based on Unity3D. A five-pass algorithm is used to create a virtual fisheye camera. This synthetic training data is evaluated for the application of free space detection for different deep learning network architectures. The results indicate that synthetic fisheye images can be used in deep learning context.

description: We report on the calibration of a superfluid $^3$He bolometer developed for the search of non-baryonic Dark Matter. Precise thermometry is achieved by the direct measurement of thermal excitations using Vibrating Wire Resonators (VWRs). The heating pulses for calibration were produced by the direct quantum process of quasiparticle generation by other VWRs present. The bolometric calibration factor is analyzed as a function of temperature and excitation level of the sensing VWR. The calibration is compared to bolometric measurements of the nuclear neutron capture reaction and heat depositions by cosmic muons and low energy electrons. The comparison allows a quantitative estimation of the ultra-violet scintillation rate of irradiated helium, demonstrating the possibility of efficient electron recoil event rejection.

description: The purpose of this thesis research is to a) promote collaboration between archaeologists, federal agencies, and repositories, through museum-based archaeology, b) bring attention to an under-researched region of the Southwest, c) understand the use of Catclaw Cave, d) understand Patayan culture and use of the Lower Colorado River Valley, and e) identify potential trade networks between inhabitants of the Lower Colorado River Valley and other communities in the Southwest. This thesis, which focuses on habitation and lifeways prior to contact with Europeans, is guided by the hypothesis that the Colorado River served as a major trade route for people living in the Southwest. Most re-analysis methods used during this project were non-destructive. They focused on the styles, constructions, or types of ceramic, lithic, faunal, and floral artifacts recovered from Catclaw Cave in order to compare them to other sites in the region.

description: Achieving versatile robot locomotion requires motor skills which can adapt to previously unseen situations. We propose a Multi-Expert Learning Architecture (MELA) that learns to generate adaptive skills from a group of representative expert skills. During training, MELA is first initialised by a distinct set of pre-trained experts, each in a separate deep neural network (DNN). Then by learning the combination of these DNNs using a Gating Neural Network (GNN), MELA can acquire more specialised experts and transitional skills across various locomotion modes. During runtime, MELA constantly blends multiple DNNs and dynamically synthesises a new DNN to produce adaptive behaviours in response to changing situations. This approach leverages the advantages of trained expert skills and the fast online synthesis of adaptive policies to generate responsive motor skills during the changing tasks. Using a unified MELA framework, we demonstrated successful multi-skill locomotion on a real quadruped robot that performed coherent trotting, steering, and fall recovery autonomously, and showed the merit of multi-expert learning generating behaviours which can adapt to unseen scenarios.

description: We analyse the dynamics of a probe D3-(anti-)brane propagating in a warped string compactification, making use of the Dirac-Born-Infeld action approximation. We also examine the time dependent expansion of such moving branes from the ``mirage cosmology'' perspective, where cosmology is induced by the brane motion in the background spacetime. A range of physically interesting backgrounds are considered: AdS5, Klebanov-Tseytlin and Klebanov-Strassler. Our focus is on exploring what new phenomenology is obtained from giving the brane angular momentum in the extra dimensions. We find that in general, angular momentum creates a centrifugal barrier, causing bouncing cosmologies. More unexpected, and more interesting, is the existence of bound orbits, corresponding to cyclic universes.

The recent AI outbreak in the Midwest has resulted in the infection of over 48 million birds on 223 farms.  Infected birds are euthanized to help contain the disease, resulting in large economic loss to both the grower and integrator.  
	With this in mind, poultry growers and companies often have questions about potential liability if AI breaks out on one farm (Grower A) and then on a neighboring farm (Grower B).  Could Grower A be liable to Grower B for damages caused by the disease?  Under the traditional view, Grower A would not be liable for the spread of the disease unless it was shown that Grower A was negligent.  Growers, poultry companies, and contractors practicing biosecurity measures can demonstrate he/she was not negligent and is working to prevent the spread of AI

description: Recent observations have pointed out various anomalies in some multipoles (small $\ell $) of the cosmic microwave background (CMB). In this paper, it is proved that some of these anomalies could be explained in the framework of a modified concordance model, in which, there is an appropriate distribution of vector perturbations with very large spatial scales. Vector modes are associated with divergenceless (vortical) velocity fields. Here, the generation of these modes is not studied in detail (it can be done "a posteriori"); on the contrary, we directly look for the distributions of these vector modes which lead to both alignments of the second and third multipoles and a planar octopole. A general three-dimensional (3D) superimposition of vector perturbations does not produce any alignment, but we have found rather general 2D superimpositions leading to anomalies similar to the observed ones; in these 2D cases, the angular velocity has the same direction at any point of an extended region and, moreover, this velocity has the same distribution in all the planes orthogonal to it. Differential rotations can be seen as particular cases, in which, the angular velocity only depends on the distance to a rotation axis. Our results strongly suggest that appropriate mixtures of scalar and vector modes with very large spatial scales could explain the observed CMB anomalies.

description: I discuss some aspects of the recent test of frame-dragging performed by me by exploiting the Root-Mean-Square (RMS) orbit overlap differences of the out-of-plane component N of the orbit of the Mars Global Surveyor (MGS) spacecraft in the gravitational field of Mars. A linear fit of the full time series of the entire MGS data (4 February 1999-14 January 2005) yields a normalized slope 1.03 +/- 0.41 (with 95% confidence bounds). Other linear fits to different data sets confirm the agreement with general relativity. The huge systematic effects induced by the mismodeling in the martian gravitational field claimed by some authors are absent in the MGS out-of-plane record. The non-gravitational forces affect at the same level of the gravitomagnetic one the in-plane orbital components of MGS, not the out-of-plane one. Moreover, they experience high-frequency variations which does not matter in the present case in which secular effects are relevant.

Imitation Learning for Autonomous Highway Merging with Safety Guarantees

Subjects: Uncategorized

description: Thanks to the innovations in Artificial Intelligence, the autonomous driving field experienced an enormous growth in recent years, opening the road to a new safe and efficient way of conceiving transportation. One of the most challenging aspects is designing a driverless car able to safely navigate the highway. A particularly critical maneuver is merging in the highway traffic coming from an on-ramp, which will be the focus of this thesis. The described task is an highly interactive process, that requires an advanced level of cooperation between drivers. In similar cases, machine learning techniques have demonstrated to be more efficient than manually designed rule-based approaches. In particular, in this work we consider the Imitation Learning (IL) approach, whose objective is to learn how to perform a task by imitating the demonstrations of an expert. The result is a policy that the agent can follow to perform as similar as possible to the expert. Behavioral Cloning (BC) and Inverse Reinforcement Learning (IRL) are the two main approaches in Imitation Learning. The former uses supervised learning to find a policy that imitates the expert. This method is simple and efficient but it suffers from cascading error. The latter, instead, resorts to methods of solving an MDP when the reward function is unknown. This approach allows to learn a reward function, that constitutes a transferable representation of the desired behavior, but it is computationally more expensive and requires the knowledge of the model dynamics. The imitation technique proposed in this thesis builds on the Behavioral Cloning approach and augments it with a safety filter that covers the cascading error issue. This approach preserves the benefits of using a BC-based technique, while overcoming its limitations with an additional controller to ensure safety. In this work, we explore the state-of-the-art of Imitation Learning, present our method and analyze the results of applying it to the highway merging scenario.
Design of a Novel Method to Bend Mandibular Plates for Reconstruction Surgeries

description: The paper focuses on the design of a system used to bend mandibular reconstruction plates, taking into account the dimensional differences of individual bone structures of patients. It may be considered a part of the pre-surgery planning procedures carried out for mandibular reconstruction surgeries. Mandibular reconstruction is a kind of surgery performed for the correction of deformed or damaged mandibles (the lower jaw bone). Bone grafts are generally held in place with the help of Grade 5 Titanium plates, bent manually as per the dimensions of the patient’s bone structure. The project has been divided into two main stages : determining the angles to which the plate is to be bent and the design and assembly of the plate bending machine. The paper consists of the research and the subsequent design of a machine to automate this process, with a broader aim to reduce the manual work carried out by surgeons prior to the surgery, subsequently reducing the time required for the mechanical aspects of surgery planning.

description: Malicious software threats and their detection have been gaining importance as a subdomain of information security due to the expansion of ICT applications in daily settings. A major challenge in designing and developing anti-malware systems is the coverage of the detection, particularly the development of dynamic analysis methods that can detect polymorphic and metamorphic malware efficiently. In the present study, we propose a methodological framework for detecting malicious code by analyzing run trace outputs by Long Short-Term Memory (LSTM). We developed models of run traces of malicious and benign Portable Executable (PE) files. We created our dataset from run trace outputs obtained from dynamic analysis of PE files. The obtained dataset was in the instruction format as a sequence and was called Instruction as a Sequence Model (ISM). By splitting the first dataset into basic blocks, we obtained the second one called Basic Block as a Sequence Model (BSM). The experiments showed that the ISM achieved an accuracy of 87.51% and a false positive rate of 18.34%, while BSM achieved an accuracy of 99.26% and a false positive rate of 2.62%.

description: We analyze in details a conditional measurement scheme based on linear optical components, feed-forward loop and homodyne detection. The scheme may be used to achieve two different tasks. On the one hand it allows the extraction of information with minimum disturbance about a set of coherent states. On the other hand, it represents a nondemolitive measurement scheme for the annihilation operator, i.e. an indirect measurement of the Q-function. We investigate the information/disturbance trade-off for state inference and introduce the estimation/distortion trade-off to assess estimation of the Q-function. For coherent states chosen from a Gaussian set we evaluate both information/disturbance and estimation/distortion trade-offs and found that non universal protocols may be optimized in order to achieve better performances than universal ones. For Fock number states we prove that universal protocols do not exist and evaluate the estimation/distortion trade-off for a thermal distribution.

description: MATLAB has emerged as one of the languages most commonly used by scientists and engineers for technical computing, with ~1,000,000 users worldwide. The compute intensive nature of technical computing means that many MATLAB users have codes that can significantly benefit from the increased performance offered by parallel computing. pMatlab (www.ll.mit.edu/pMatlab) provides this capability by implementing Parallel Global Array Semantics (PGAS) using standard operator overloading techniques. The core data structure in pMatlab is a distributed numerical array whose distribution onto multiple processors is specified with a map construct. Communication operations between distributed arrays are abstracted away from the user and pMatlab transparently supports redistribution between any block-cyclic-overlapped distributions up to four dimensions. pMatlab is built on top of the MatlabMPI communication library (www.ll.mit.edu/MatlabMPI) and runs on any combination of heterogeneous systems that support MATLAB, which includes Windows, Linux, MacOSX, and SunOS. Performance is validated by implementing the HPC Challenge benchmark suite and comparing pMatlab performance with the equivalent C+MPI codes. These results indicate that pMatlab can often achieve comparable performance to C+MPI at usually 1/10th the code size. Finally, we present implementation data collected from a sample of 10 real pMatlab applications drawn from the ~100 users at MIT Lincoln Laboratory. These data indicate that users are typically able to go from a serial code to a well performing pMatlab code in about 3 hours while changing less than 1% of their code.

description: Dynamic networks of concurrent pushdown systems (DCPS) are a theoretical model for multi-threaded recursive programs with shared global state and dynamical creation of threads. The (global) state reachability problem for DCPS is undecidable in general, but Atig et al. (2009) showed that it becomes decidable, and is in 2EXPSPACE, when each thread is restricted to a fixed number of context switches. The best known lower bound for the problem is EXPSPACE-hard and this lower bound follows already when each thread is a finite-state machine and runs atomically to completion (i.e., does not switch contexts). In this paper, we close the gap by showing that state reachability is 2EXPSPACE-hard already with only one context switch. Interestingly, state reachability analysis is in EXPSPACE both for pushdown threads without context switches as well as for finite-state threads with arbitrary context switches. Thus, recursive threads together with a single context switch provide an exponential advantage. Our proof techniques are of independent interest for 2EXPSPACE-hardness results. We introduce transducer-defined Petri nets, a succinct representation for Petri nets, and show coverability is 2EXPSPACE-hard for this model. To show 2EXPSPACE-hardness, we present a modified version of Lipton's simulation of counter machines by Petri nets, where the net programs can make explicit recursive procedure calls up to a bounded depth.
Characterization of a Quorum Sensing System Important for Pneumococcal Pathogenesis

description: Quorum Sensing (QS), or bacterial communication by intercellular chemical signaling, is a process common to many (if not most) bacterial species; yet, it is unclear how QS signaling pathways contribute to virulence in many clinically significant pathogens. The Federle lab has helped to characterize a family of transcriptional regulators, known as Rgg proteins, as mediators of QS. We and others have shown the importance of Rgg proteins in multiple species of streptococci in regulating expression of genes that may enhance their ability to colonize and infect the host. The role of the Rgg proteins in the pathogenic lifestyle of Streptococcus pneumoniae is just beginning to be investigated. Published genome-level mutagenesis studies indicate Rgg proteins in this organism are critical in models of infection. Additionally, recent studies have confirmed the contribution of Rgg0141 to bacterial fitness in vivo. However, it is unclear which genetic factors regulated by Rgg0141 are responsible for this virulence phenotype. Using RNA-sequencing technology, we have identified numerous virulence factors belonging to the Rgg0141 regulon, such as the manganese transport system psaBCA, the pore-forming toxin, pneumolysin (ply), and the previously described bacteriocin containing operon vp1BCD. Luciferase reporter assays have allowed us to monitor QS system induction and regulation of target genes under a variety of conditions, specifically in the presence and absence of the signaling pheromone SHP0141 and under varying manganese concentrations. Using an infection model of pneumonia, we have demonstrated the importance of Rgg0141 and vp1BC for competitive fitness in the lungs and blood of mice. Additionally, we have taken a biochemical approach in order to describe the binding kinetics of Rgg0141-SHP0141 to DNA. The methodology of our studies can be extended to other bacteria, as QS occurs in many other bacterial populations and the Rgg proteins can be found in a variety of bacterial species. Understanding the molecular networks under QS regulation is the first step towards developing novel therapeutic approaches that could slow down the development of drug resistance and be more effective at combating clinically significant pathogens.

description: Bidirectional Long Short-Term Memory Network (Bi-LSTM) has shown promising performance in sentiment classification task. It processes inputs as sequence of information. Due to this behavior, sentiment predictions by Bi-LSTM were influenced by words sequence and the first or last phrases of the texts tend to have stronger features than other phrases. Meanwhile, in the problem scope of Indonesian sentiment analysis, phrases that express the sentiment of a document might not appear in the first or last part of the document that can lead to incorrect sentiment classification. To this end, we propose the using of an existing document representation method called paragraph vector as additional input features for Bi-LSTM. This vector provides information context of the document for each sequence processing. The paragraph vector is simply concatenated to each word vector of the document. This representation also helps to differentiate ambiguous Indonesian words. Bi-LSTM and paragraph vector were previously used as separate methods. Combining the two methods has shown a significant performance improvement of Indonesian sentiment analysis model. Several case studies on testing data showed that the proposed method can handle the sentiment phrases position problem encountered by Bi-LSTM.

description: High turnover contributes to the United States’ nurse shortage, particularly new graduate nurses’ (NGN) high rate of departure (27.6%) within their first year of practice. Low nursing competency is often responsible for NGNs’ high turnover rate. Although employer orientation programs develop NGNs’ hard skills (knowledge and performance), achieving satisfactory levels of soft skills (attitudes and behaviors) is also essential to NGNs’ competency and retention. However, the intangible nature of soft skills makes it difficult to evaluate. To address this issue, in Phase I, an integrative literature review explored NGNs’ self-assessed competencies. In Phase II, based on review findings and Benner’s framework “From Novice to Expert,” a qualitative descriptive study identified critical soft skills and developed behavioral indicators at four competency levels for each skill: beginning, developing, accomplished, and exemplary. In Phase I, a database search ultimately yielded 16 articles that were evaluated for quality. These articles provided descriptions of NGNs’ self-assessed competencies, classified as perceived strengths and weaknesses that informed the qualitative descriptive study. Purposeful sampling recruited 13 clinical nurse educators/preceptors from multiple units in one large hospital. One-on-one participant interviews were audio-recorded, transcribed, and subjected to direct content analysis using NVivo. Finally, the literature review and qualitative study findings were compared. Phase I findings revealed that NGNs’ self-assessed strengths focused on technical skills and clinical knowledge while their weaknesses focused primarily on soft skills: communication, teamwork, helping role, and professionalism. Phase II data analysis revealed five soft skill themes: personal growth, effective interaction, professionalism, teamwork, and caring role. Descriptors of four competency levels were derived for 20 subthemes. This study is the first to identify critical soft skills to be evaluated in NGNs. The study results provide a useful guide for academic and clinical nurse educators’ assessments of NGNs’ developing competencies. These assessments will promote improvement in NGN soft skill competencies and ultimately NGNs’ retention in practice. The end goal of this research is to apply the study findings to the construction of a clinical assessment rubric for soft skills in NGNs and other nurses.
Proficiency testing in clinical chemistry

description: In this thesis we will investigate proficiency testing in clinical chemistry. External quality control agencies utilize proficiency testing programs in order to assess and improve the analytical performance of clinical laboratories. In particular, we will consider the CHEMPLUS proficiency testing program which has been developed by the Canadian Reference Laboratory (C.R.L.) The CHEMPLUS program is designed to assess the validity of clinical tests performed by a laboratory, that is, the laboratory's analytical performance. Statistically valid and medically relevant evaluation criteria should be used to assess laboratory performance. However, there is debate whether this requirement is fulfilled by the use of current evaluation methodology. We will use data from the CHEMPLUS proficiency testing program to compare several standard methods of evaluating laboratory performance. In addition, we will construct an overall measure of laboratory performance that can be used to rank clinical laboratories.

description: We report the discovery of two highly dispersed pulsars in the direction of the Galactic Centre made during a survey at 3.1 GHz with the Parkes radio telescope. Both PSRs J1745-2912 and J1746-2856 have an angular separation from the Galactic Centre of less than 0.3 degrees and dispersion measures in excess of 1100 cm-3pc, placing them in the top 10 pulsars when ranked on this value. The frequency dependence of the scatter-broadening in PSR J1746-2856 is much shallower than expected from simple theory. We believe it likely that the pulsars are located between 150 and 500 pc from the Galactic Centre on the near side, and are part of an excess population of neutron stars associated with the Centre itself. A second survey made at 8.4 GHz did not detect any pulsars. This implies either that there are not many bright, long-period pulsars at the Galactic Centre or that the scattering is more severe at high frequencies than current models would suggest.

The Disjointed Self: Interrogating Interiority in the Collage Works of Romare Bearden and Wangechi Mutu

description: This thesis examines the collage works of modernist artist Romare Bearden and contemporary, postmodern artist Wangechi Mutu in order to examine a historical shift occurring between the mid-1960s and the early 2000s-2010s. Both artists are concerned with recontextualizing representations of black subjects, but while Bearden’s disjointed figures are grounded in reality in their placement within urban scenes, Mutu’s alien-human fusions are often depicted in extraterrestrial environments. Bearden’s modern black figures signal a reach for universality through the very particularity of the manner in which they have been constructed, whereas Mutu’s fierce glamazon goddesses abandon modernist selfhood for the shared language of critique, each seamlessly embodying a catalog of traumatizing subject positions. This project approaches both artists’ works through an analysis of existing scholarship and suggests new frameworks through which to consider their work.

description: Electrification of transport in RES-based power system will support the decarbonisation of the transportsector. However, due to the increase in energy demand and the large peak effects of charging, the passiveintegration of electric cars is likely to undermine sustainability efforts. This study investigates three differentcharging strategies for electric vehicle in Europe offering various degrees of flexibility: passive charging,smart charging and vehicle-to-grid, and puts this flexibility in perspective with the flexibility offered byinterconnections. We use the Balmorel optimization tool to represent the short-term dispatch and long-terminvestment in the energy system and we contribute to the state-of-the-art in developing new methodologiesto represent home charging and battery degradation. Our results show how each step of increased chargingflexibility reduces system costs, affects energy mix, impacts spot prices and reduces CO2 emissions untilthe horizon 2050. We quantify how flexible charging and variable generation mutually support each other(Â¿100TWh from wind and solar energy in 2050) and restrict the business case for stationary batteries, whereaspassive charging results in a substitution of wind by solar energy. The comparison of each charging schemewith and without interconnection expansion highlights the interplay between European countries in terms ofelectricity prices and CO2 emissions in the context of electrified transport. Although the best outcome isreached under the most flexible scenario at the EU level, the situation of the countries with the cheapest andmost decarbonised electricity mix is damaged, which calls for adapted coordination policy at the EU level.

description: This paper presents symmetry classes of the Hartree-Fock (HF) solutions of spin and orbital ordered states in a t_{2g} Hubbard model on a two-dimensional square lattice. Using a group theoretical bifurcation theory of the Hartree Fock equation, we obtained many types of broken symmetry solutions which bifurcate from the normal state through one step transition in cases of commensurate ordering vectors Q_0=(0,0), Q_1=(π,π), Q_2=(π,0) and Q_3=(0,π). Each broken symmetry state is characterized by the presence of local order parameters(LOP) at each lattice site: quadrupole moment Q=(Q_2^2,Q_{12},Q_{23},Q_{31}), orbital angular momentum l=(l_1,l_2,l_3), spin density s=(s^1,s^2,s^3), spin quadrupole moment Q^λ=(Q_2^{2λ}, Q_{12}^λ,Q_{23}^λ,Q_{31}^λ) and spin orbital angular momentum l^λ=(l_1^λ,l_2^λ,l_3^λ) where λ=1,2,3. We performed numerical calculations for some parameter sets. Then we have found that many types of non-collinear magnetic orbital ordered states having LOP:Q^λ and l^λ can be the ground state for these parameter sets.

description: Feature selection for a given model can be transformed into an optimization task. The essential idea behind it is to find the most suitable subset of features according to some criterion. Nature-inspired optimization can mitigate this problem by producing compelling yet straightforward solutions when dealing with complicated fitness functions. Additionally, new mathematical representations, such as quaternions and octonions, are being used to handle higher-dimensional spaces. In this context, we are introducing a meta-heuristic optimization framework in a hypercomplex-based feature selection, where hypercomplex numbers are mapped to real-valued solutions and then transferred onto a boolean hypercube by a sigmoid function. The intended hypercomplex feature selection is tested for several meta-heuristic algorithms and hypercomplex representations, achieving results comparable to some state-of-the-art approaches. The good results achieved by the proposed approach make it a promising tool amongst feature selection research.

description: The universal analytic expressions in the limit of low temperatures (short separations) are obtained for the free energy, entropy and pressure between the two parallel plates made of any dielectric. The analytical proof of the Nernst heat theorem in the case of dispersion forces acting between dielectrics is provided. This permitted us to formulate the stringent thermodynamical requirement that must be satisfied in all models used in the Casimir physics.
