description: Nowadays, automation of manufacturing advertising frameworks gains particular relevance. Currently, NC machines are widely used at enterprises in various production branches, which requires a specialist that could exploit them with the highest efficiency. This design is aimed at the developing a technological solution to the problem of automation of manufacturing processes involving NC machines on the example of manufacturing a logotype for the Department of Applied Mechanics at National aerospace university “KhAI”. The main parts of the logo are: a gear wheel, a gripper, a sub gripper, a hinge joint (2), text, a backside, an accessory part, a bearing. The department logotype was designed in Solid Works environment. The designed patterns of the logo were adopted for the Autodesk environment by saving files in DFX format. This makes it possible to write a part processing program. The logo processing technology is framed considering the type of manufacturing procedure and with the use of high-yield equipment. Mechanical processing is fixed, the path of the tool is demonstrated and the control program for milling operations is received. In case the logotype is manufactured as an exterior decorative element, while designing it is necessary to consider the model of the cutting tool and the cutting depth in order to visually specify some fragments of the parts and their mutual bracing. The design of the framework can be considered as a sample of automation of manufacturing outdoor advertisement by means of a modern machine – tool with NC operation system.

description: Since game-based learning require much planning and careful design, and also tailoring the learning content to game structures, the uptake of gamebased learning activities remains limited, as their construction often requires a significant amount of time, and the reuse capabilities of such activities are minimal. This paper describes how the different components of a gamified lessons path can be adapted and reused. In order to ensure the reusability of the different learning paths, a set of minigame templates has been used.

description: Currently, there is no widespread and free validation tool for examining flexible public transportation systems and testing theories. In transport, the application of reimagined flexible passenger transportation systems, which generate lower energy need and provider’s cost, is becoming more and more popular. Based on previous own research results and new flexible transportation management theories (A-FTS), this validation program will be described. The flexible transport systems currently in use provide the design concepts on the basis of which a full validation system can be developed. This will provide the basis for starting to explore and implement flexible transport systems to exploit their potential.

description: Let $G$ be an abelian Polish group, e.g. a separable Banach space. A subset $X \subset G$ is called Haar null (in the sense of Christensen) if there exists a Borel set $B \supset X$ and a Borel probability measure $μ$ on $G$ such that $μ(B+g)=0$ for every $g \in G$. The term shy is also commonly used for Haar null, and co-Haar null sets are often called prevalent. Answering an old question of Mycielski we show that if $G$ is not locally compact then there exists a Borel Haar null set that is not contained in any $G_δ$ Haar null set. We also show that $G_δ$ can be replaced by any other class of the Borel hierarchy, which implies that the additivity of the $σ$-ideal of Haar null sets is $ω_1$. The definition of a generalised Haar null set is obtained by replacing the Borelness of $B$ in the above definition by universal measurability. We give an example of a generalised Haar null set that is not Haar null, more precisely we construct a coanalytic generalised Haar null set without a Borel Haar null hull. This solves Problem GP from Fremlin's problem list. Actually, all our results readily generalise to all Polish groups that admit a two-sided invariant metric.

description: During the manufacture of flats and terrazzo, grinding and polishing operations are compulsory, which are carried out with abrasive wheels. The work deals with the obtaining and evaluation of abrasive materials from aluminothermic processing of solid industrial waste and Cuban minerals. Different mixtures composed of mill scale and aluminum chips to which different proportions of limestone are added are studied. As a result of the process, a high hardness ceramic is obtained as the main product, and a metal as a by-product. The results of the process are evaluated from the metal and slag yields. The behavior of the ceramics as an abrasive material is evaluated by means of scratch tests on glass, and the behavior of the powders during setting with P-350 cement is also evaluated. Finally, an assessment is made for the possible assembly of a Pilot Plant for the manufacture of abrasive powders, which guarantees the possibility of producing these materials on a pilot plant scale where all the construction and logistical aspects for their subsequent exploitation are assessed.

description: Opinion mining, also known as sentiment analysis, is a subfield of natural language processing (NLP) that focuses on identifying and extracting subjective information in textual material. This can include determining the overall sentiment of a piece of text (e.g., positive or negative), as well as identifying specific emotions or opinions expressed in the text, that involves the use of advanced machine and deep learning techniques. Recently, transformer-based language models make this task of human emotion analysis intuitive, thanks to the attention mechanism and parallel computation. These advantages make such models very powerful on linguistic tasks, unlike recurrent neural networks that spend a lot of time on sequential processing, making them prone to fail when it comes to processing long text. The scope of our paper aims to study the behaviour of the cutting-edge Transformer-based language models on opinion mining and provide a high-level comparison between them to highlight their key particularities. Additionally, our comparative study shows leads and paves the way for production engineers regarding the approach to focus on and is useful for researchers as it provides guidelines for future research subjects.
Piecewise Principal Coactions of Co-Commutative Hopf Algebras

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: Principal comodule algebras can be thought of as objects representing principal bundles in non-commutative geometry. A crucial component of a principal comodule algebra is a strong connection map. For some applications it suffices to prove that such a map exists, but for others, such as computing the associated bundle projectors or Chern-Galois characters, an explicit formula for a strong connection is necessary. It has been known for some time how to construct a strong connection map on a multi-pullback comodule algebra from strong connections on multi-pullback components, but the known explicit general formula is unwieldy. In this paper we derive a much easier to use strong connection formula, which is not, however, completely general, but is applicable only in the case when a Hopf algebra is co-commutative. Because certain linear splittings of projections in multi-pullback comodule algebras play a crucial role in our construction, we also devote a significant part of the paper to the problem of existence and explicit formulas for such splittings. Finally, we show example application of our work.

description: In this paper, we investigate the low temperature magnetic properties of the rare-earth garnet compound Nd$_3$Ga$_5$O$_{12}$ in detail by means of magnetization, specific heat and magnetocaloric effect measurements. The magnetic thermal properties along with the crystal field calculations reveal that the Nd$^{3+}$ ions form into a frustrated hyper-kagome lattice with connected triangles have an Ising-like ground state with the easy axis along the local [100], [010] and [001] directions. Instead of a quantum spin liquid ground state, an antiferromagnetically ordered state is found below $T_{\mathrm{N}}=0.52~\rm K$. With applying field in the [111] direction, the antiferromagnetic order is suppressed at the critical field of $B_{\mathrm{c}}=0.75~\rm T$, and enhancement of the critical fluctuations with linear crossover behaviors is observed near the critical point.

description: Value Stream Management in its conventional methodology underlies several disadvantages, especially in the context of effort and flexibility. The approach is characterized as time- and resource-consuming due to a mainly pen-and-paper based procedure, causing inflexibility in an increasing dynamic environment. Taking these findings into account the term static VSM in contrast to a dynamic VSM or VSM 4.0 is introduced in some studies. The fundamental principles of VSM are recognized as still valid, whereas the procedure requires improvements in regard to flexibility and accuracy to ensure a future-viability in today’s environments. Recent studies show the relevance and importance of this topic and provide proposals for improving the methodology by the application of information and communication technologies. All reviewed studies have in common a selective consideration of one or more technologies for improving the methodology. Missing is a holistic analysis of the potentials of a digital value stream map, implemented as data-based model with reference to the Value Stream Management phases value stream mapping (VSM), value stream analysis (VSA), value stream design (VSD) and value stream planning (VSP). Based on a literature review for analyzing the state of research in a holistic way, the paper aims at providing a framework, consolidating all recent researches in one model.

description: When disclosing limited and redacted records about the May 10th 2006 complaint filed against pedophile teacher Scott Paul Beierle, the Anne Arundel County Police Department (located in Millersville, Maryland) denied ever being contacted by the Department of Homeland Security (DHS) United States Secret Service (USSS) for the purpose their March 15th 2022 report, which went on to summarize the life of racist and sexist Scott Paul Beierle in a 28 (twenty-eight) page document. The disclosures of the Anne Arundel County Police Department confirm that Scott Paul Beierle was employed as a teacher in the State of Maryland (from 2005 through 2007) and that he sexually harassed at least one of his underage female students by [1] invading her personal space; [2] making inappropriate remarks about the type of clothing she ought to be wearing; [3] initiating a very intrusive line of questioning. As a matter of principle, the Association for the Advancement of Civil Liberties (AACL) unequivocally condemns violence committed against women irrespective of their racial backgrounds, their sexual orientations, their national origins, their religious affiliations, their disability status and/or their age groups. For what seems very obvious reasons, the AACL is deeply concerned by the decision of the Department of Justice (DOJ) Federal Bureau of Investigation (FBI) to take some responsibility for the February 14th 2018 shooting in Parkland, Florida while at the same time not taking any responsibility for the November 02nd 2018 shooting in Tallahassee, Florida even though the circumstances that led up to both those shootings are similar.

Investigating Locked Nucleic Acids as efficient disruptors of DNA G-quadruplex structures in vitro and in cells
Creators: name: Chowdhury, Souroprobho
Publisher: name: Imperial College London
Year: 2023

description: G-quadruplexes (G4s) are non-canonical secondary structures of DNA that are prevalent within the human genome. In the last 30 years, advances in genomics, bioinformatics and imaging have unravelled various biological roles of G4s, including regulation of gene expression, translation, and replication. Most of the tools currently available to investigate G4-biology rely on small molecule ligands that stabilise these structures. However, the development of probes that disrupt G4s is equally important to study their biology, given the body of evidence suggesting that the uncontrolled cellular accumulation of G4s is associated with neurodegenerative diseases and accelerated ageing. In this thesis, a suite of biophysical, biochemical, and cellular approaches was used to systematically investigate how efficient disruption of G4s can be achieved by using Locked Nucleic Acids (LNA)-modified oligonucleotides as invader probes. The data generated through these investigations revealed that the strategic positioning of LNA-modifications within oligonucleotide sequences complementary to G4s can significantly accelerate the kinetics of G4-disruption, compared to unmodified oligonucleotides. Furthermore, it was demonstrated that LNA-modifications can be leveraged to design oligonucleotide probes as short as 10 nucleotides, which were found to be efficient at disrupting G4s under physiological conditions. These observations were consistent across two distinct G4 systems. The application of the designed LNA modified G4-disrupting probes in a reporter-based cellular assay revealed that disrupting a specific G4 located in the promoter region of the oncogene c-KIT results in significantly increased gene-expression levels. Collectively, these suggest that strategically designed LNA-modified oligonucleotide probes are accessible chemical biology tools that could be used by the wider scientific community to interrogate the biology associated with the disruption of specific G4s in the human genome and may in the future be leveraged to develop G4-targeting therapeutics.
The Continuity Method to Deform Cone Angle

description: The continuity method is used to deform the cone angle of a weak conical Kähler-Einstein metric with cone singularities along a smooth anti-canonical divisor on a smooth Fano manifold. This leads to an alternative proof of Donaldson's Openness Theorem on deforming cone angle \cite{Don} by combining it with the regularity result of Guenancia-P$\breve{\text{a}}$un \cite{GP} and Chen-Wang \cite{CW}. This continuity method uses relatively less regularity of the metric (only weak conical Kähler-Einstein) and bypasses the difficult Banach space set up; it is also generalized to deform the cone angles of a \emph{weak conical Kähler-Einstein metric} along a simple normal crossing divisor (pluri-anticanonical) on a smooth Fano manifold (assuming no tangential holomorphic vector fields).

description: Computational notebooks, tools that facilitate storytelling through exploration, data analysis, and information visualization, have become the widely accepted standard in the data science community. These notebooks have been widely adopted through notebook software such as Jupyter, Datalore and Google Colab, both in academia and industry. While there is extensive research to learn how data scientists use computational notebooks, identify their pain points, and enable collaborative data science practices, very little is known about the various accessibility barriers experienced by blind and visually impaired (BVI) users using these notebooks. BVI users are unable to use computational notebook interfaces due to (1) inaccessibility of the interface, (2) common ways in which data is represented in these interfaces, and (3) inability for popular libraries to provide accessible outputs. We perform a large scale systematic analysis of 100000 Jupyter notebooks to identify various accessibility challenges in published notebooks affecting the creation and consumption of these notebooks. Through our findings, we make recommendations to improve accessibility of the artifacts of a notebook, suggest authoring practices, and propose changes to infrastructure to make notebooks accessible.

description: Is there an initialization for deep networks that requires no learning? ExplainFix adopts two design principles: the "fixed filters" principle that all spatial filter weights of convolutional neural networks can be fixed at initialization and never learned, and the "nimbleness" principle that only few network parameters suffice. We contribute (a) visual model-based explanations, (b) speed and accuracy gains, and (c) novel tools for deep convolutional neural networks. ExplainFix gives key insights that spatially fixed networks should have a steered initialization, that spatial convolution layers tend to prioritize low frequencies, and that most network parameters are not necessary in spatially fixed models. ExplainFix models have up to 100x fewer spatial filter kernels than fully learned models and matching or improved accuracy. Our extensive empirical analysis confirms that ExplainFix guarantees nimbler models (train up to 17\% faster with channel pruning), matching or improved predictive performance (spanning 13 distinct baseline models, four architectures and two medical image datasets), improved robustness to larger learning rate, and robustness to varying model size. We are first to demonstrate that all spatial filters in state-of-the-art convolutional deep networks can be fixed at initialization, not learned.

description: In this work, we study an inflationary scenario in the presence of Generalized Chaplygin Gas (GCG). We show that in Einstein gravity, GCG is not a suitable candidate for inflation; but in a five dimensional brane world scenario, it can work as a viable inflationary model. We calculate the relevant quantities such as $n_{s}$, $r$ and $A_{s}$ related to the primordial scalar and tensor fluctuations, and using their recent bounds from Planck and BICEP2, we constrain the model parameters as well as the five-dimensional Planck mass. But as a slow-roll inflationary model with a power-law type scalar primordial power spectrum, GCG as an inflationary model can not resolve the tension between results from BICEP2 and Planck with a concordance $Λ$CDM Universe. We show that going beyond the concordance $Λ$CDM model and incorporating more general dark energy behaviour, this tension may be eased. We also obtain the constraints on the $n_{s}$ and $r$ and the GCG model parameters using Planck+WP+BICEP2 data considering the CPL dark energy behaviour.

description: Quantum computers have great potential to change the future of Artificial Intelligence (AI) applications for practical problems. There currently exist some algorithm design that takes exponential time on a classical computer can take polynomial time on a quantum computer. With high demand for fast and reliable AI applications, such as traffic sign recognition for Intelligent Transportation Systems, it is beneficial for society and smart infrastructure to develop and utilise the most suitable AI algorithms for Quantum Computers (QCs). This Ph.D research project aims to focus on the feasibility of QCs to implement the image multi class classification techniques used in various domains, including AI applications. Moreover, in this study new successful techniques such Quantum Neural Network algorithms will also be explored to improve the efficiency of quantum image processing algorithms on QCs based on the similarity of these techniques with the mechanics of the QCs. This PhD research is expected to contribute to the knowledge domains in areas of real-life road traffic signs. The objectives of the research are: (i) To develop a new image-based multiclass classification algorithm using the quantum entanglement approach in comparison with classical machine learning (CML). (ii) To design a new filter for image processing to determine efficiency of quantum machine learning over CML. (iii) To investigate proposed quantum filter for binary image classification of complex traffic signs on small sample data. Within the context of these goals, this project is a partnership between Commonwealth Scientific and Industrial Research Organization (CSIRO) and University of Southern Queensland, which aims to build cutting-edge algorithms and novel methods for future QCs. The designed algorithms will be implemented in the Python software interface on available online quantum simulators. The scientific contributions indicate remarkable improvement in our model's performance on black and white images. However, we did not observe Quantum Machine Learning (QML) performing better for complex traffic signs using multi-class classification. Nevertheless, we achieved good results with binary image classification. This research will contribute to the scientific foundation for future applications of AI in quantum computers.

description: The procedure developed allows self-assessment according to the level of certification chosen. Quality management tools are used, the application of which increases in complexity as excellence in product storage is sought. In addition, the aim is to test the adaptability of the applied tool and to analyze the data obtained from the different entities. Once the procedure is applied, it allows to analyze and improve the logistics of the warehouses in the studied entities. It is also carried out the survey of the logistics status of warehouses to initiate the implementation of logistics 4.0 in Cuban entities of products and services. This procedure incorporates the knowledge of logistics 4.0 to the tools, and highlights the importance of updating logistics processes. The research is applied: in the Central Ronera Agustín Rodríguez Mena, in the beverage and liquor warehouse of the hotel "Las Cuevas", in the UEB #1 Tabaco Torcido de exportación Santa Clara and in the warehouse of the commercial unit La Sandalia. The problem to be solved is to obtain the level of certification of the warehouse in the different entities according to the preceding level they had certified, allowing to check the adaptability of the applied tool and to analyze the data obtained from the different entities A procedure is offered to search, analyze and provide solutions to the problems faced by entities in countries with fewer resources in the process of achieving the objectives of logistics 4.0. Among the main limitations are: little knowledge of logistics 4.0 on the part of the workers and managers of the entities, as well as resistance to change on the part of the workers of the entities. The application of the selected procedure concludes with an analysis of the problems detected and proposed solutions to achieve the improvement of logistics in the warehouse so that it can be certified at the current level or at a higher level.

description: Based on protein molecular dynamics, we investigate the fractal properties of energy, pressure and volume time series using the multifractal detrended fluctuations analysis (MF-DFA) and the topological and fractal properties of their converted horizontal visibility graphs (HVGs). The energy parameters of protein dynamics we considered are bonded potential, angle potential, dihedral potential, improper potential, kinetic energy, Van der Waals potential, electrostatic potential, total energy and potential energy. The shape of the h(q) curves from MF-DFA indicates that these time series are multifractal. The numerical values of the exponent h(2) of MF-DFA show that the series of total energy and potential energy are non-stationary and anti-persistent; the other time series are stationary and persistent apart from series of pressure (with H approx 0.5 indicating the absence of long-range correlation). The degree distribution of their converted HVGs show that these networks are exponential. The results of fractal analysis show that fractality exists in these converted HVGs. For each energy, pressure or volume parameter, it is found that the values of h(2) of MF-DFA on the time series, exponent lambda of the exponential degree distribution and fractal dimension d_B of their converted HVGs do not change much for different proteins (indicating some universality). We also found that after taking average over all proteins, there is a linear relationship between < h(2)> (from MF-DFA on time series) and of the converted HVGs for different energy, pressure and volume.

description: Quantum entanglement plays a central role in many areas of physics, from quantum information science to many-body systems. In order to grasp the essence of this phenomenon, it is fundamental to understand how different manifestations of entanglement relate to each other. In 1999, Peres conjectured that Bell nonlocality is equivalent to distillability of entanglement. The intuition of Peres was that the non-classicality of an entangled state, as witnessed via Bell inequality violation, implies that pure entanglement can be distilled from this state, hence making it useful for most quantum information protocols. Subsequently, the Peres conjecture was shown to hold true in several specific cases, and became a central open question in quantum information theory. Here we disprove the Peres conjecture by showing that an undistillable bipartite entangled state---a bound entangled state---can nevertheless violate a Bell inequality. This shows that Bell nonlocality implies neither entanglement distillability, nor non-positivity under partial transposition, thus clarifying the relation between three fundamental aspects of entanglement. Finally, our results lead to a novel application of bound entanglement for device-independent randomness certification.

description: We study the genuine multipartite entanglement of arbitrary $n$-partite quantum states by representing the density matrices in terms of the generalized Pauli operators. We introduce a general framework for detecting genuine multipartite entanglement and non full-separability of multipartite quantum states with arbitrary dimensions based on correlation tensors. Effective criterion is derived to verify the genuine multipartite entanglement. Detailed examples are given to show that the criterion detects more genuine multipartite entanglement than the existing criteria.

description: Nowadays logistic service providers (LSP) are facing more and more regulations and political measures concerning sustainability. This paper presents the first results and discussions of a simulation on environmental policy measures in the transport sector. The additional costs of these measures were calculated for two ideal truck models over the next four years. Besides higher fuel costs due to a gradual increase in certificate costs, which translates to additional costs of €6,949 or 4.9 cents per km for a EURO 6 truck with an annual mileage of 140,000 km, the new published truck toll costs for 2024 cause a high increase of additional environmental costs. All measures combined result in additional costs of €61,806 for a EURO 6 and €65,638 EURO 5 truck. The study also calculates the total cost of ownership (TCO) for a single truck and finds that the additional environmental costs would cause additional costs of 53.74% to 57.07% for the selected truck model. The study notes that the cost difference cannot be integrated in current transport prices due to an average profit margin of only 3,4% for LSP companies. Therefore, the authors point out the importance of an overall simulation model.
An approximate version of the Tree Packing Conjecture

description: We prove that for any pair of constants $ε>0$ and $Δ$ and for $n$ sufficiently large, every family of trees of orders at most $n$, maximum degrees at most $Δ$, and with at most $\binom{n}{2}$ edges in total packs into $K_{(1+ε)n}$. This implies asymptotic versions of the Tree Packing Conjecture of Gyarfas from 1976 and a tree packing conjecture of Ringel from 1963 for trees with bounded maximum degree. A novel random tree embedding process combined with the nibble method forms the core of the proof.

Search for top-quark partners with charge 5/3 in the same-sign dilepton final state

description: A search for the production of heavy partners of the top quark with charge 5/3 is performed in events with a pair of same-sign leptons. The data sample corresponds to an integrated luminosity of 19.5 inverse femtobarns and was collected at sqrt(s) = 8 TeV by the CMS experiment. No significant excess is observed in the data above the expected background and the existence of top-quark partners with masses below 800 GeV is excluded at a 95% confidence level, assuming they decay exclusively to tW. This is the first limit on these particles from the LHC, and it is significantly more restrictive than previous limits.

description: Principal component regression (PCR) is a two-stage procedure that selects some principal components and then constructs a regression model regarding them as new explanatory variables. Note that the principal components are obtained from only explanatory variables and not considered with the response variable. To address this problem, we propose the sparse principal component regression (SPCR) that is a one-stage procedure for PCR. SPCR enables us to adaptively obtain sparse principal component loadings that are related to the response variable and select the number of principal components simultaneously. SPCR can be obtained by the convex optimization problem for each of parameters with the coordinate descent algorithm. Monte Carlo simulations and real data analyses are performed to illustrate the effectiveness of SPCR.

description: We study fast lattice decodability of space-time block codes for $n$ transmit and receive antennas, written very generally as a linear combination $\sum_{i=1}^{2l} s_i A_i$, where the $s_i$ are real information symbols and the $A_i$ are $n\times n$ $\mathbb R$-linearly independent complex valued matrices. We show that the mutual orthogonality condition $A_iA_j^* + A_jA_i^*=0$ for distinct basis matrices is not only sufficient but also necessary for fast decodability. We build on this to show that for full-rate ($l = n^2$) transmission, the decoding complexity can be no better than $|S|^{n^2+1}$, where $|S|$ is the size of the effective real signal constellation. We also show that for full-rate transmission, $g$-group decodability, as defined in [1], is impossible for any $g \ge 2$. We then use the theory of Azumaya algebras to derive bounds on the maximum number of groups into which the basis matrices can be partitioned so that the matrices in different groups are mutually orthogonal---a key measure of fast decodability. We show that in general, this maximum number is of the order of only the $2$-adic value of $n$. In the case where the matrices $A_i$ arise from a division algebra, which is most desirable for diversity, we show that the maximum number of groups is only $4$. As a result, the decoding complexity for this case is no better than $|S|^{\lceil l/2 \rceil}$ for any rate $l$.
