description: Nuclei from a variety of tissues displayed wide differences in the rate of cleavage of chromatin DNA by the endogenous nuclease(s). However, at the nucleosomal level of chromatin organization, both the linker DNA and the nucleosome core were cleaved during incubation of nuclei from all tissues examined, as well as in rat thymocytes following the injection of glucocorticoid. The transcribed ovalbumin gene in hen oviduct nuclei was cleaved selectively by the endogenous nuclease as compared to the bulk of the DNA and inactive globin genes as revealed by both solution and Southern blot hybridization analysis. Preferential digestion of the ovalbumin sequence was clearly apparent after 20 min of nuclear incubation. In addition, in nuclei from immature chick oviducts, the nuclease sensitivity of the ovalbumin gene paralleled the differential expression of this gene during primary estrogen stimulation, estrogen withdrawal, and secondary hormone stimulation, thus implying that transcribed oviduct chromatin is most accessible to this nuclease. Since the rapid autodigestion of DNA in isolated nuclei does not normally occur in intact cells, some type of nuclease activation process or change in the chromatin substrate must occur during nuclear preparation or incubation. The autodigestion process in nuclei was inhibited by spermine4+, spermidine3+,Ca2+, Mg2+, Na+, and K+ and the degree of this inhibition was proportional to the effectiveness of these cations in promoting the precipitation of nuclease-sheared chromatin. Incubation of nuclei in buffers containing cationic compositions that are thought to be similar to the in vivo state resulted in essentially complete inhibition of nuclease activity and maximal precipitation of chromatin. The rate of the selective fragmentation of the ovalbumin gene, like the bulk of the nuclear DNA, was reduced upon increasing the cationic concentration of the nuclear incubation medium. These results suggest that the activation of chromatin autodigestion during nuclear incubation results from a reduction in the cationic composition of nucleoplasm and, once activated, the endogenous nuclease selectively attacks transcribed genes in chromatin.

Conformation of ovalbumin and globin genes in chromatin during differential gene expression

description: Micrococcal nuclease and DNase I were used to study changes in the chromatin conformation of ovalbumin and globin genes during differential expression of these sequences. Oviduct nuclei, obtained from estrogen-treated chicks or chicks withdrawn from the hormone for 3, 4, or 6 days, were incubated with micrococcal nuclease until 1 to 3% of the DNA was rendered acid-soluble. The resulting DNA fragments then were separated into four size classes. In the stimulated oviducts, the concentration of the ovalbumin gene in mononucleosome-length DNA (165 to 200 base pairs) was 6-fold greater than in the fraction containing DNA fragments >1300 base pairs in length. This selective cleavage decreased progressively as a function of estrogen withdrawal time and correlated temporally with a decline in the concentration of oviduct nuclear estrogen receptors. The expressed globin genes in immature erythrocyte nuclei were also cleaved preferentially by micrococcal nuclease, whereas the transcriptionally silent globin sequences in mature erythrocyte nuclei were not. The globin genes in both immature and mature erythrocyte nuclei were destroyed by DNase I 3 times faster than the greater part of the nuclear DNA. To determine if the globin genes in the mature erythrocyte were cleaved preferentially by DNase I, nuclei were incubated with this enzyme until 1 to 3% of the DNA was rendered acid-soluble. The resulting DNA fragments then were separated into four size classes. The concentration of globin genes in the size class containing the smallest DNA fragments (less than 300 base pairs) from both immature and mature erythrocyte nuclei was about 6-fold greater than in undigested DNA, and about 15-fold greater than in the fraction containing DNA fragments >1200 base pairs in length. These results suggest that the micrococcal nuclease sensitive conformation of the ovalbumin and globin genes in chromatin is dynamically related to the expression of these sequences. The DNase I sensitive structure as determined by both nucleolytic destruction and cleavage, in contrast, remains associated with globin sequences following their inactivation.

description: The dynamics of a single impurity interacting with a many particle background is one of the central problems of condensed matter physics. Recent progress in ultracold atom experiments makes it possible to control this dynamics by coupling an artificial gauge field specifically to the impurity. In this paper, we consider a narrow toroidal trap in which a Fermi gas is interacting with a single atom. We show that an external magnetic field coupled to the impurity is a versatile tool to probe the impurity dynamics. Using Bethe Ansatz (BA) we calculate the eigenstates and corresponding energies exactly as a function of the flux through the trap. Adiabatic change of flux connects the ground state to excited states due to flux quantization. For repulsive interactions, the impurity disturbs the Fermi sea by dragging the fermions whose momentum matches the flux. This drag transfers momentum from the impurity to the background and increases the effective mass. The effective mass saturates to the total mass of the system for infinitely repulsive interactions. For attractive interactions, the drag again increases the effective mass which quickly saturates to twice the mass of a single particle as a polaron of the impurity and one fermion is formed. For excited states with momentum comparable to number of particles, effective mass shows a resonant behavior. We argue that standard tools in cold atom experiments can be used to test these predictions.

description: A Random SubMatrix method (RSM) is proposed to calculate the low-rank decomposition of large-scale matrices with known entry percentage ρ. RSM is very fast as the floating-point operations (flops) required are compared favorably with the state-of-the-art algorithms. Meanwhile RSM is very memory-saving. With known entries homogeneously distributed in the given matrix, sub-matrices formed by known entries are randomly selected. According to the just proved theorem that subspace related to smaller singular values is less perturbed by noise, the null vectors or the right singular vectors associated with the minor singular values are calculated for each submatrix. The vectors are the null vectors of the corresponding submatrix in the ground truth of the given large-scale matrix. If enough sub-matrices are randomly chosen, the low-rank decomposition is estimated. The experimental results on random synthetical matrices with sizes such as 131072X1024 and on real data sets indicate that RSM is much faster and memory-saving, and, meanwhile, has considerable high precision achieving or approximating to the best.
Non-normal modalities in variants of Linear Logic

description: This article presents modal versions of resource-conscious logics. We concentrate on extensions of variants of Linear Logic with one minimal non-normal modality. In earlier work, where we investigated agency in multi-agent systems, we have shown that the results scale up to logics with multiple non-minimal modalities. Here, we start with the language of propositional intuitionistic Linear Logic without the additive disjunction, to which we add a modality. We provide an interpretation of this language on a class of Kripke resource models extended with a neighbourhood function: modal Kripke resource models. We propose a Hilbert-style axiomatization and a Gentzen-style sequent calculus. We show that the proof theories are sound and complete with respect to the class of modal Kripke resource models. We show that the sequent calculus admits cut elimination and that proof-search is in PSPACE. We then show how to extend the results when non-commutative connectives are added to the language. Finally, we put the logical framework to use by instantiating it as logics of agency. In particular, we propose a logic to reason about the resource-sensitive use of artefacts and illustrate it with a variety of examples.

Fractionation and characterization of chromosomal proteins by the hydroxyapatite dissociation method

name: Anderson, J.N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1978

description: A method was developed which enables the characterization and fractionation of chromosomal proteins according to their chromatin binding properties. The method is based on the ability of hydroxyapatite to bind native chromatin in solutions which do not dissociate chromosomal proteins from the DNA. The proteins are then selectively dissociated from the immobilized chromatin by treatment with NaCl, urea, or guanidine HCl. The hydroxyapatite dissociation method represents a rapid one-step fractionation procedure which results in the quantitative recovery of chromosomal proteins devoid of nucleic acids and is suitable for large preparations. The hydroxyapatite dissociation method provides a versatile procedure for the study and preparation of chromosomal proteins. The patterns of dissociation of both histones and nonhistone chromosomal proteins by NaCl and urea from chicken oviduct chromatin were characterized by this method. In addition, this technique enabled the purification of the major histone species in a single operation. Partial purification of specific nonhistone proteins, including the estrogen receptor, was also achieved. We suggest that this method will be a useful tool in elucidation of the chemical and biological properties of the proteins from chromatin.

description: The transformation of power grids into intelligent cyber-physical systems brings numerous benefits, but also significantly increases the surface for cyber-attacks, demanding appropriate countermeasures. However, the development, validation, and testing of data-driven countermeasures against cyber-attacks, such as machine learning-based detection approaches, lack important data from real-world cyber incidents. Unlike attack data from real-world cyber incidents, infrastructure knowledge and standards are accessible through expert and domain knowledge. Our proposed approach uses domain knowledge to define the behavior of a smart grid under non-attack conditions and detect attack patterns and anomalies. Using a graph-based specification formalism, we combine cross-domain knowledge that enables the generation of whitelisting rules not only for statically defined protocol fields but also for communication ows and technical operation boundaries. Finally, we evaluate our specification-based intrusion detection system against various attack scenarios and assess detection quality and performance. In particular, we investigate a data manipulation attack in a future-orientated use case of an IEC 60870-based SCADA system that controls distributed energy resources in the distribution grid. Our approach can detect severe data manipulation attacks with high accuracy in a timely and reliable manner.

description: For the family of polynomials in one variable $P:=x^n+a_1x^{n-1}+\cdots +a_n$, $n\geq 4$, we consider its higher-order discriminant sets $\{ \tilde{D}_m=0\}$, where $\tilde{D}_m:=$Res$(P,P^{(m)})$, $m=2$, $\ldots$, $n-2$, and their projections in the spaces of the variables $a^k:=(a_1,\ldots ,a_{k-1},a_{k+1},\ldots ,a_n)$. Set $P^{(m)}:=\sum _{j=0}^{n-m}c_ja_jx^{n-m-j}$, $P_{m,k}:=c_kP-x^mP^{(m)}$. We show that Res$(\tilde{D}_m,\partial \tilde{D}_m/\partial a_k,a_k)= A_{m,k}B_{m,k}C_{m,k}^2$, where $A_{m,k}=a_n^{n-m-k}$, $B_{m,k}=$Res$(P_{m,k},P_{m,k}')$ if $1\leq k\leq n-m$ and $A_{m,k}=a_{n-m}^{n-k}$, $B_{m,k}=$Res$(P^{(m)},P^{(m+1)})$ if $n-m+1\leq k\leq n$. The equation $C_{m,k}=0$ defines the projection in the space of the variables $a^k$ of the closure of the set of values of $(a_1,\ldots ,a_n)$ for which $P$ and $P^{(m)}$ have two distinct roots in common. The polynomials $B_{m,k},C_{m,k}\in \mathbb{C}[a^k]$ are irreducible. The result is generalized to the case when $P^{(m)}$ is replaced by a polynomial $P_*:=\sum _{j=0}^{n-m}b_ja_jx^{n-m-j}$, $0\neq b_i\neq b_j\neq 0$ for $i\neq j$.
TIDAL DISRUPTION EVENTS IN THE ERA OF MULTIMESSENGER ASTRONOMY
Creators: name: TOSCANI, MARTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2021

description: Tidal Disruption Events (TDEs) occur when a star, wandering too close to a black hole (BH), is torn apart by BH tides. After the disruption, roughly half of the stellar debris is expected to circularize around the BH and eventually form an accretion disc. These events represent a unique way to detect BHs through the universe since they emit both electromagnetic (EM) radiation and gravitational waves (GWs). In fact, after returning to the pericenter, the stellar material accretes onto the central object, producing very luminous EM flares. To date, around 50 robust TDEs have been detected in different bands of the EM spectrum (optical, X-ray, radio). Furthermore, these events also produce GWs during the whole process: while the star is stretched and compressed by BH tides, when the star is disrupted at pericenter and during the circularization process. So far, these gravitational signals have been inaccessible to us since they are low-frequency signals. Hence, these events will be seen by the future space-based detectors (like LISA and deci-Hertz observatories). In the upcoming future, thanks to the synergy between the spatial GW observatories and new and more performant telescopes, we will observe these events both via GWs and EM radiation. This will provide us a unique and more complete way to study BHs. Given these premises, this Thesis aims to study the main features of TDE gravitational emission, both through analytical and numerical studies. In particular, I explore the signal from an individual TDE, focussing on the emission generated at later stages during the circularization of the debris. Then, I investigate the signal produced by the entire cosmic population of tidal disruptions. Finally, I illustrate a catalogue of gravitational waveforms from TDEs built with a numerical tool implemented by myself during the PhD.

description: In this article, we examine the representation of right-wing extremism, left-wing extremism and Islamism in the media-public discourse using the example of SPIEGEL Online, one of the leading German media. We derive four central dimensions for the conceptualization of extremisms: ideological foundation, origin of the actors, position towards society and typical actions. We observe the development of the representation of extremisms at potential breakpoints: We investigate the associative framing of the extremisms before and after a prominent extremism-related violent event, namely 9/11, the publication of the NSU scandal and left-wing extremist activities during the G20 summit. We observe changes in framing motivated by the selected events and compare the resulting framing with the current definitions of the Federal Office for the Protection of the Constitution, in order to work out possible differences in the conceptualization of extremism variants with potentially different logics of action to be expected from diverging conceptualisations.

description: Very recently, it was demonstrated that the carrier mobility of a molecular monolayer dioctylbenzothienobenzothiophene (C8-BTBT) on boron nitride can reach 10 cm2/Vs, the highest among the previously reported monolayer molecular field-effect transistors. Here we show that the high-quality single crystal of the C8-BTBT monolayer may be the key origin of the record-high carrier mobility. We discover that the C8-BTBT molecules prefer layer-by-layer growth on both hexagonal boron nitride and graphene. The flatness of these substrates substantially decreases the C8-BTBT nucleation density and enables repeatable growth of large-area single crystal of the C8-BTBT monolayer. Our experimental result indicates that only out-of-plane roughness greater than 0.6 nm of the substrates could induce disturbance in the crystal growth and consequently affect the charge transport. This information would be important in guiding the growth of high-quality epitaxy molecular film.

The Role of Self-compassion in Neurological Conditions
Creators: name: Hawkes, Meg
Publisher: name: Lancaster University
Year: 2023

description: This thesis explores the role self-compassion may play within neurological conditions. Section one includes a scoping review which examines how self-compassion is investigated within neurological conditions, with a particular focus on intervention studies. Five academic databases were searched in November 2022 and 17 papers met all criteria and were included. The interventions utilised could be broadly split into two types, compassion-focused (such as Compassion Focused Therapy) and mindfulness-based (such as Mindfulness Based Stress Reduction). The compassion-focused studies did not always measure self-compassion, which meant that changes in outcomes could not be clearly attributed to changes in self-compassion. Both intervention types targeted changes to well-being and physical health or psychological distress. Findings suggested that developing self-compassion may take time, which has implications both clinically and for research. Suggestions for future research are made, including the methodology and measures used for investigating self-compassion and the neurological conditions examined. Section two involves an empirical study investigating the role of self-compassion and experiential avoidance in functional seizures. People who experience functional seizures completed an online survey including measures of self-compassion, experiential avoidance, depressive symptoms, seizure severity, seizure frequency and quality-of-life. Correlational and mediation analyses were conducted to examine the relationships between all variables. Correlational relationships were all in expected directions, apart from seizure frequency which did not have a significant relationship with self-compassion. Experiential avoidance significantly mediated the relationship between self-compassion and several outcomes (depressive symptoms, quality-of-life, and seizure severity). These findings suggest the importance of developing compassion-cultivating interventions for those with functional seizures. Section three is the critical appraisal, which reflects on the decisions made and any issues which arose during the process of conducting this project.

description: Loop interference (LI) in wireless communications, is a notion resulting from the full-duplex (FD) operation. In a large-scale network, FD also increases the multiuser interference due to the large number of active wireless links that exist. Hence, in order to realize the FD potentials, this interference needs to be restricted. This paper presents a stochastic geometry model of FD cellular networks where the users and base stations employ directional antennas. Based on previous experimental results, we model the passive suppression of the LI at each FD terminal as a function of the angle between the two antennas and show the significant gains that can be achieved by this method. Together with the reduction of multiuser interference resulting from antenna directionality, our model demonstrates that FD can potentially be implemented in large-scale directional networks.

description: Overview: This thesis explored concepts related to the experiences of living with Functional Neurological Disorder (FND). FND is known as a heterogeneous presentation of neurological symptoms that cannot be explained through known disease pathologies. Systematic Literature Review: The systematic literature review explored the experiences of health care professionals engaging individuals with functional seizures, in healthcare interactions. The review identified that healthcare professionals described engagement as successful when they; acknowledged the challenges and systemic difficulties with the condition; adapted for the individual, both being flexible in-service provision and in strategies used by the professional, and when the individual’s social network were consistent with their understanding and support. Empirical Paper: The empirical paper explored how individuals with Functional Neurological Disorder ‘lived well’ with the condition. The results were divided into four themes (1) Knowing and prioritising your values; (2) Having control of the narrative; (3) Navigating personal and therapeutic relationships and (4) Developing personal coping strategies. The results of this paper suggested that ‘living well’ with FND, was different for each individual based on their values, beliefs, and social environment. Critical Appraisal: The critical appraisal discusses further strengths and limitations of the research, reflections of the researcher and clinical implications.

description: AIMS: The object W Aql is an asymptotic giant branch (AGB) star with a faint companion. By determining more carefully the properties of the companion, we hope to better constrain the properties of the AGB star. METHODS: We present new spectral observations of the binary star W Aql at minimum and maximum brightness and new photometric observations of W Aql at minimum brightness. RESULTS: The composite spectrum near minimum light is predominantly from the companion at wavelengths $λ$ < 6000 $Å$. This spectrum can be classified as F8 to G0, and the brightness of the companion is that of a dwarf star. Therefore, it can be concluded that the companion is a main sequence star. From this, we are able to constrain the mass of the AGB component to 1.04 - 3 $M_\odot$ and the mass of the W Aql system to 2.1 - 4.1 $M_\odot$ . Our photometric results are broadly consistent with this classification and suggest that the main sequence component suffers from approximately 2 mag of extinction in the V band primarily due to the dust surrounding the AGB component.

description: We consider multi-component quantum mixtures (bosonic, fermionic, or mixed) with strongly repulsive contact interactions in a one-dimensional harmonic trap. In the limit of infinitely strong repulsion and zero temperature, using the class-sum method, we study the symmetries of the spatial wave function of the mixture. We find that the ground state of the system has the most symmetric spatial wave function allowed by the type of mixture. This provides an example of the generalized Lieb-Mattis theorem. Furthermore, we show that the symmetry properties of the mixture are embedded in the large-momentum tails of the momentum distribution, which we evaluate both at infinite repulsion by an exact solution and at finite interactions using a numerical DMRG approach. This implies that an experimental measurement of the Tan's contact would allow to unambiguously determine the symmetry of any kind of multi-component mixture.

description: BPS coherent states closely resemble semiclassical states and they have gravity dual descriptions in terms of semiclassical geometries. The half BPS coherent states have been well studied, however less is known about quarter BPS coherent states. Here we provide a construction of quarter BPS coherent states. They are coherent states built with two matrix fields, generalizing the half BPS case. These states are both the eigenstates of annihilation operators and in the kernel of dilatation operator. Another useful labeling of quarter BPS states is by representations of Brauer algebras and their projection onto a subalgebra $\mathbb{C}[S_n\times S_m]$. Here, the Schur-Weyl duality for the Walled Brauer algebra plays an important role in organizing the operators. One interesting subclass of these Brauer states are labeled by representations involving two Young tableaux. We obtain the overlap between quarter BPS Brauer states and quarter BPS coherent states, where the Schur polynomials are used. We also derive superposition formulas transforming a truncated version of quarter BPS coherent states to quarter BPS Brauer states. The entanglement entropy of Brauer states as well as the overlap between Brauer states and squeezed states are also computed.

description: In real-world optimization scenarios, the problem instance that we are asked to solve may change during the optimization process, e.g., when new information becomes available or when the environmental conditions change. In such situations, one could hope to achieve reasonable performance by continuing the search from the best solution found for the original problem. Likewise, one may hope that when solving several problem instances that are similar to each other, it can be beneficial to ``warm-start'' the optimization process of the second instance by the best solution found for the first. However, it was shown in [Doerr et al., GECCO 2019] that even when initialized with structurally good solutions, evolutionary algorithms can have a tendency to replace these good solutions by structurally worse ones, resulting in optimization times that have no advantage over the same algorithms started from scratch. Doerr et al. also proposed a diversity mechanism to overcome this problem. Their approach balances greedy search around a best-so-far solution for the current problem with search in the neighborhood around the best-found solution for the previous instance. In this work, we first show that the re-optimization approach suggested by Doerr et al. reaches a limit when the problem instances are prone to more frequent changes. More precisely, we show that they get stuck on the dynamic LeadingOnes problem in which the target string changes periodically. We then propose a modification of their algorithm which interpolates between greedy search around the previous-best and the current-best solution. We empirically evaluate our smoothed re-optimization algorithm on LeadingOnes instances with various frequencies of change and with different perturbation factors and show that it outperforms both a fully restarted (1+1) Evolutionary Algorithm and the re-optimization approach by Doerr et al.

description: Point cloud compression (PCC) is a key enabler for various 3-D applications, owing to the universality of the point cloud format. Ideally, 3D point clouds endeavor to depict object/scene surfaces that are continuous. Practically, as a set of discrete samples, point clouds are locally disconnected and sparsely distributed. This sparse nature is hindering the discovery of local correlation among points for compression. Motivated by an analysis with fractal dimension, we propose a heterogeneous approach with deep learning for lossy point cloud geometry compression. On top of a base layer compressing a coarse representation of the input, an enhancement layer is designed to cope with the challenging geometric residual/details. Specifically, a point-based network is applied to convert the erratic local details to latent features residing on the coarse point cloud. Then a sparse convolutional neural network operating on the coarse point cloud is launched. It utilizes the continuity/smoothness of the coarse geometry to compress the latent features as an enhancement bit-stream that greatly benefits the reconstruction quality. When this bit-stream is unavailable, e.g., due to packet loss, we support a skip mode with the same architecture which generates geometric details from the coarse point cloud directly. Experimentation on both dense and sparse point clouds demonstrate the state-of-the-art compression performance achieved by our proposal. Our code is available at https://github.com/InterDigitalInc/GRASP-Net.
