description: We introduce randomness into a class of integrable models and study the spectral form factor as a diagnostic to distinguish between randomness and chaos. Spectral form factors exhibit a characteristic dip-ramp-plateau behavior in the $N>2$ SYK$_2$ model at high temperatures that is absent in the $N=2$ SYK$_2$ model. Our results suggest that this dip-ramp-plateau behavior implies the existence of random eigenvectors in a quantum many-body system. To further support this observation, we examine the Gaussian random transverse Ising model and obtain consistent results without suffering from small $N$ issues. Finally, we demonstrate numerically that expectation values of observables computed in a random quantum state at late times are equivalent to the expectation values computed in the thermal ensemble in a Gaussian random one-qubit model.

description: This paper presents the findings of a three-year longitudinal study (Grades 9–11; N = 756 students in German secondary schools; mean starting age = 14.7 years) that explores the development of and the interplay between upper-secondary students’ individual interest and conceptual understanding in chemistry. Students’ individual interest was assessed in seven dimensions of school science activities (realistic, investigative, artistic, social, conventional, and networking) according to Dierks et al.'s RIASEC+N model. The data was collected annually using paper-and-pencil questionnaires. In order to analyse the longitudinal relation between students’ academic interest and conceptual understanding, Eccles et al.'s Expectancy-Value Theoretical Model of Achievement Choices (EEVT) was utilised and seven bivariate cross-lagged models were performed to investigate the assumed reciprocal relations between both constructs. Regarding the developmental progression of individual interest and conceptual knowledge, latent growth curve models indicate a small decrease in all of the seven dimensions of students’ interest in school science activities and concomitant a moderate growth of students’ conceptual understanding. Moreover, structural equation modelling suggests weak reciprocal relations between students’ conceptual understanding and their interest in investigative, social and networking school science activities, respectively. Furthermore, students’ interest in enterprising activities predicted their subsequent conceptual understanding. No systematic pattern of cross-lagged effects between the three remaining interest dimensions and conceptual understanding were found. The results indicate that school science activities, which provide the potential for cognitively activating learning opportunities, could enhance the relation between students’ interest and conceptual understanding. Implications for teaching practice and further research are discussed.

description: The number and quality of oocytes in the ovarian reserve are related to fertility and reproductive lifespan in mammals. Some transcription factors have been demonstrated to determine oogenesis. The insulinoma-associated 2 (Insm2) gene is a member of the Snail transcriptional repressor superfamily. Recent studies have demonstrated Insm2 plays an essential role for insulin secretion and glucose intolerance in mice, but the functions of Insm2 in reproduction remain elusive. Here, by examination of Insm2 knockout mice, we found Insm2 was essential for female fertility. Loss of Insm2 resulted in female infertility with major defects in primordial follicle pool, ovarian folliculogenesis and ovulation. Transcriptomic profiling of ovaries suggests that loss of Insm2 caused defects in oocyte meiosis and steroid synthesis. Both oocyte- and granulosa cell-expressed genes were dysregulated, including Foxo1 and other known genes involved in primary ovarian insufficiency. Together, these studies show that Insm2 is required for oocyte development and their communication with ovarian somatic cells.
Using Corbino disk sample geometry to separate quasiparticle and vortex motion contributions to the mixed state dissipation of YBCO

description: A method, using a Corbino disk sample geometry, is described and applied to study of resistive tails of sintered $YBCO$. When the transport current passes radially from the rim of the disk sample to its center, the two component potential drop signal is detected below $T_c$, which is due to (i) quasiparticles $W_q$ and (ii) vortex-core-motion related contribution $W_{ϕ}$. When the contact pairs for $W$ are placed radially, $W_q(r)$ and $W_{ϕ}(r)$ are found to follow the markedly distinctive functional dependences, providing a unique possibility to deconvolute the relative strengths of both contributions. The results obtained suggest that the mixed state dissipation of high-$T_c$ superconductors is strongly influenced by the quasiparticle excitations.

description: Inverted hybrid inflation (in which the inflaton field slowly rolls away from the origin, giving a spectral index $n\lsim 1$) is an appealing variant of the more usually studied hybrid model. Analysing the model alongside the ordinary hybrid case, we show that, in order to provide the correct density perturbations consistent with the COBE measurements, the dimensionless coupling constants of the inverted hybrid potential must be very small indeed. For example, the quartic coupling in a typical such potential is found to be $\lsim 10^{-12}$. A supersymmetric model of inverted hybrid inflation, which does not involve the troublesome quartic coupling is found to lead to a potential which is unbounded from below.

description: We perform a precision computation of hybrid static potentials with quantum numbers $Λ_η^ε= Σ_g^-,Σ_u^+,Σ_u^-,Π_g,Π_u,Δ_g,Δ_u$ using SU(3) lattice gauge theory. The resulting potentials are used to estimate masses of heavy $\bar{c} c$ and $\bar{b} b$ hybrid mesons in the Born-Oppenheimer approximation. Part of the lattice gauge theory computation, which we discuss in detail, is an extensive optimization of hybrid static potential creation operators. The resulting optimized operators are expected to be essential for future projects concerning the computation of 3-point functions as e.g. needed to study spin corrections, decays or the gluon distribution of heavy hybrid mesons.

description: We present a study of phase separation from supersaturated 3He-4He liquid mixtures at low temperatures addressing both the degree of critical supersaturation Dx and the thermal-to-quantum crossover temperature T* for the nucleation process. Two different nucleation seeds are investigated, namely 3He droplets and 4He vortex lines with cores filled with 3He. We have found that the experimental T* is reproduced when we consider that nucleation proceeds from 3He droplets, whereas Dx is reproduced when we consider 4He vortex lines filled with 3He. However, neither nucleation configuration is able to simultaneously reproduce the current experimental information on Dx and T*.

description: My dissertation addresses the question of how we ought to care for and engage with people with cognitive disabilities. The project has two main goals: the first is to develop a more robust account of care ethics, and the second is to use this newly developed account to theorize about current conceptions of how we ought to treat individuals with cognitive disabilities. First, I address the theoretical problem of how to make ‘care’ a robust enough concept to govern our ethical treatment of others. I address the primary problem care ethicists have traditionally had with conceiving of care as a virtue: virtues are egoistically focused on eudaimonia or self-happiness. I suggest this concern can be avoided if the aim of virtues was to develop flourishing relationships rather than individual character. With a conception of care established, I proceed to consider whether we have developed the right moral and epistemic virtues to properly care for people with cognitive disabilities. I argue that individuals with cognitive disabilities, regardless of the severity of their disability, face a variety of epistemic injustices that negatively impacts the care they receive and the relationships that they are able to form. Then, I consider whether individuals with cognitive disabilities are able to care for others as others can care for them. While caring for others is obviously not beyond the capability of those with disabilities that are traditionally classified as ‘mild’ or ‘moderate,’ I suggest that even those with what we would consider ‘severe’ impairments are able to care. Finally, I consider one specific practical implication of a system of ethics that appropriately recognizes the epistemic and moral contributions of individuals with cognitive disabilities. I consider how college instructors can use their position of authority to better care for students with learning disabilities in their classrooms.

description: Background: The present study investigated the possible cardioprotective effects of GLP1 and SGLT2i against diabetic cardiomyopathy (DCM) in type 2 diabetic rats and the possible underlying mechanisms. DCM is defined as the presence of heart failure in absence of coronary artery disease. Methods: Thirty-two male Sprague Dawley rats were randomly subdivided into 4 equal groups; a) control group, b) DM group, type 2 diabetic rats with saline daily for 4 weeks, c) DM+ GLP1, as DM group with GLP1 analogue (liraglutide) at a dose of 75 µg/kg for 4 weeks, and d) DM+ SGLT2i: as DM group with SGLT2 inhibitor (dapagliflozin) at a dose of 1mg/kg for 4 weeks. By the end of treatment (4 weeks), serum blood glucose, HOMA-IR, insulin and cardiac enzymes (LDH, CK-MB) were measured. Also, the cardiac histopathology, myocardial oxidative stress markers (MDA, GSH and CAT) and norepinephrine (NE), myocardial fibrosis, the expression of caspase-3, TGF-β, TNF-α and tyrosine hydroxylase (TH) in myocardial tissues were measured. Results: T2DM caused significant increase in serum glucose, HOMA-IR, serum CK-MB and LDH (p< 0.05). Also, DM caused significant myocardial damage and fibrosis, elevation of myocardial MDA, NE with upregulation of myocardial caspase-3, TNF-α, TGF-β and TH and significant decrease in serum insulin and myocardial GSH and CAT (p<0.05). Administration of either GLP1 analog and SGLT2i caused in significant improvement in all studied parameters (p< 0.05). Conclusion: We concluded that either of GLP1 and SGLT2i exhibited cardioprotective effects against DCM in T2DM with the upper hand for SGLT2i. This might be due to attenuation of fibrosis, oxidative stress, apoptosis (caspase-3), sympathetic nerve activity and inflammatory cytokines (TNF-α and TGF-β).
Helicity-Flip Off-Foward Parton Distributions of the Nucleon

description: We identify quark and gluon helicity-flip distributions defined between nucleon states of unequal momenta. The evolution of these distributions with change of renormalization scale is calculated in the leading-logarithmic approximation. The helicity-flip gluon distributions do not mix with any quark distribution and are thus a unique signature of gluons in the nucleon. Their contribution to the generalized virtual Compton process is obtained both in the form of a factorization theorem and an operator product expansion. In deeply virtual Compton scattering, they can be probed through distinct angular dependence of the cross section.

description: The study focuses on the statistical analysis of the impact factors affecting Mariana Trench formation. Methodology of the work is based on plotting correlation matrices by means of R programming to visualize determinants affecting geomorphic formation of the trench. The study revealed distinct unevenness of various factors affecting Mariana Trench geomorphic structure. The bathymetric determinant of the four distinct groups of the cross section profiles cause certain variability in the sedimental thickness of the basement, slope angle steepness degree, angle aspect, depth at the basement, as well as depth values (means, median and absolute minimum). Among other factors, a magmatism of the nearby area is to be mention. The closeness of the igneous volcanic areas contribute towards earthquake frequency across four tectonic plates – Mariana, Pacific, Philippine Sea and Caroline. The results demonstrated that cross-section profiles of the Mariana Trench can be divided into clusters according to their properties, such as bathymetric (depth values), geographic (latitude and longitude), geological (width of the sedimental thickness layer), magmatism (large igneous polygon areas) and tectonic (location of the tectonic plates nearby). In the scope of current research a functionality of R programming language has been tested. It proved to be as an effective tool for studying distribution of the environmental factors affecting the tectonic structure, as well as geomorphic properties at the seafloor basement of the Mariana Trench.

description: Terahertz spectrometers with a wide instantaneous frequency coverage for passive remote sensing are enormously attractive for many terahertz applications, such as astronomy, atmospheric science and security. Here we demonstrate a wide-band terahertz spectrometer based on a single superconducting chip. The chip consists of an antenna coupled to a transmission line filterbank, with a microwave kinetic inductance detector behind each filter. Using frequency division multiplexing, all detectors are read-out simultaneously creating a wide-band spectrometer with an instantaneous bandwidth of 45 GHz centered around 350 GHz. The spectrometer has a spectral resolution of $F/ΔF=380$ and reaches photon-noise limited sensitivity. We discuss the chip design and fabrication, as well as the system integration and testing. We confirm full system operation by the detection of an emission line spectrum of methanol gas. The proposed concept allows for spectroscopic radiation detection over large bandwidths and resolutions up to $F/ΔF\sim1000$, all using a chip area of a few $\mathrm{cm^2}$. This will allow the construction of medium resolution imaging spectrometers with unprecedented speed and sensitivity.

description: The leading beta_0^(n-1) alpha_s^n terms in the Wilson coefficient and anomalous dimension of the chromomagnetic operator in the heavy-quark effective Lagrangian are summed to all orders of perturbation theory. The perturbation series for the anomalous dimension is well behaved, while that for the Wilson coefficient exhibits a divergent behaviour already in low orders, caused by a nearby infrared renormalon singularity. The resulting ambiguity is commensurate with terms of order 1/m^2 in the effective Lagrangian, whose corresponding ultraviolet renormalons are identified. An excellent approximation for the scheme-invariant Wilson coefficient at next-to-next-to-leading order in renormalization-group improved perturbation theory is obtained.

description: Systemic AA amyloidosis is still, up to this day, a life-threatening complication of chronic inflammatory diseases. Despite the success of anti-inflammatory treatment, the prognosis of some AA patients is still poor, which is why therapies directed at the amyloidogenic pathway in AA amyloidosis are being sought after. The cell culture model of amyloid formation from serum amyloid A1 (SAA1) protein remodels crucial features of AA amyloid deposit formation in vivo. We here demonstrate how the cell model can be utilized for the identification of compounds with amyloid inhibitory activity. Out of five compounds previously reported to inhibit self-assembly of various amyloidogenic proteins, we found that epigallocatechin gallate (EGCG) inhibited the formation of SAA1-derived fibrils in cell culture. From a series of compounds targeting the protein quality control machinery, the autophagy inhibitor wortmannin reduced amyloid formation, while the other tested compounds did not lead to a substantial reduction of the amyloid load. These data suggest that amyloid formation can be targeted not only via the protein self-assembly pathway directly, but also by treatment with compounds that impact the cellular protein machinery.

description: This paper touches upon the very sensitive issue of “experimental music,” with its absence of conventions, as it is usually defined in relation to the 20th century music. The history of such music is traced. Afterwards, the focus shifts to its non-communicative design that seems to unite all the different techniques it implements, as well as ways to tell it apart from music that is conventional and communicative. The ramifications of such non-communicative music for performers and musicologists are examined, which then raises the question of how necessary it actually is to study such works.

description: We study by theoretical analysis and by direct numerical simulation the dynamics of a wide class of asynchronous stochastic systems composed of many autocatalytic degrees of freedom. We describe the generic emergence of truncated power laws in the size distribution of their individual elements. The exponents $α$ of these power laws are time independent and depend only on the way the elements with very small values are treated. These truncated power laws determine the collective time evolution of the system. In particular the global stochastic fluctuations of the system differ from the normal Gaussian noise according to the time and size scales at which these fluctuations are considered. We describe the ranges in which these fluctuations are parameterized respectively by: the Levy regime $α< 2$, the power law decay with large exponent ($α> 2$), and the exponential decay. Finally we relate these results to the large exponent power laws found in the actual behavior of the stock markets and to the exponential cut-off detected in certain recent measurement.

description: In conventional superconductors, the most direct evidence of the mechanism responsible for superconductivity comes from tunneling experiments in which a clear image of the electron-phonon interaction is revealed. The observed structure in the current voltage characteristics at the phonon energies can be used to measure, through inversion of the Eliashberg equations, the electron phonon spectral density α^2F(ω). The coherence length in conventional materials is long and the tunneling process probes several atomic layers into the bulk of the superconductor. On the contrary, in the high-T_c oxides, particularly for c-axis tunneling, the coherence length can be quite short and in an optical experiment or in neutron scattering experiments the bulk of the sample is probed. Therefore, these spectroscopies become the methods of choice for the investigation of mechanisms of high-T_c superconductivity. Accurate reflectance measurements in the infrared range and precise polarized neutron scattering data are available for a variety of oxides. In this paper we show that conducting carriers studied by means of infrared spectroscopy reveal strong coupling to a resonance structure in the spectrum of spin fluctuations examined with neutron scattering. The coupling strength inferred from experiment is sufficient to account for high values of T_c which signals the prominent role of spin excitations in the superconductivity of oxides.

description: The Exploration-Exploitation tradeoff arises in Reinforcement Learning when one cannot tell if a policy is optimal. Then, there is a constant need to explore new actions instead of exploiting past experience. In practice, it is common to resolve the tradeoff by using a fixed exploration mechanism, such as $ε$-greedy exploration or by adding Gaussian noise, while still trying to learn an optimal policy. In this work, we take a different approach and study exploration-conscious criteria, that result in optimal policies with respect to the exploration mechanism. Solving these criteria, as we establish, amounts to solving a surrogate Markov Decision Process. We continue and analyze properties of exploration-conscious optimal policies and characterize two general approaches to solve such criteria. Building on the approaches, we apply simple changes in existing tabular and deep Reinforcement Learning algorithms and empirically demonstrate superior performance relatively to their non-exploration-conscious counterparts, both for discrete and continuous action spaces.

description: We study the persistent currents flowing in a mesoscopic ring threaded by a magnetic flux and connected to a stub of finite length. Multistability processes and Coulomb blockade are demonstrated to be present in this system. These properties are functions of the magnetic flux crossing the ring which plays the role that the external applied potential fulfills in the multistability behaviour of the standard mesoscopic heterostructures.

Inclusive Single- and Dijet Rates in Next-to-Leading Order QCD for gamma^*proton and gamma^*gamma Collisions

description: We present one- and two-jet inclusive cross sections for gamma*gamma scattering and virtual photoproduction in ep collisions. The hard cross sections are calculated in next-to-leading order QCD. Soft and collinear singularities are extracted using the phase-space-slicing method. The initial state singularity of the virtual photon depends logarithmically its' virtuality. This logarithm is large and has to be absorbed into the parton distribution function of the virtual photon. We define for this purpose an MS-bar factorization scheme similar to the real photon case. We numerically study the dependence of the inclusive cross sections on the transverse energies and rapidities of the outgoing jets and on the photon virtuality. The ratio of the resolved to the direct cross section in ep collisions is compared to ZEUS data.

description: In this article, we study the fully differential observables of exclusive production of heavy (charm and bottom) quark pairs in high-energy ultraperipheral $pA$ and $AA$ collisions. In these processes, the nucleus $A$ serves as an efficient source of the photon flux, while the QCD interaction of the produced heavy-quark pair with the target ($p$ or $A$) proceeds via an exchange of gluons in a color singlet state, described by the gluon Wigner distribution. The corresponding predictions for differential cross sections were obtained by using the dipole $S$-matrix in the McLerran--Venugopalan saturation model with impact parameter dependence for the nucleus target, and its recent generalization, for the proton target. Prospects of experimental constraints on the gluon Wigner distribution in this class of reactions are discussed.

description: The involvement approach to familiness tends to be important for shaping family SME resources, but it falls short in capturing the broader range of approaches to familiness such as essence approach which highlights the family members' behaviors within a family SME. Based on resource orchestration theory, this study developed a theoretical model to empirically investigate how the three different familiness resources in China's family SMEs including family dominance, emotional bonds, and family business image can impact family SME performance via entrepreneurial orientation (EO) dimensions.

description: Going by this hypothesis, the kṣatrīya reached the north-west India around 8,000 BCE. They were probably driven from their homeland by the Ice Age which reached its peak around 10,000 BCE (Last Glacial Maximum). But, by the time they crossed the Khyber Pass / Bolan Pass the ice had begun to melt, and the monsoon streams had turned into glacial torrents.Sarasvatī was one of them, the biggest of them. The kṣatrīya seem to have settled on its banks, and prospered. This agrarian civilization probably grew over time into the Indus-SarasvatīValley Civilisation or the Harappan Civilisation. This is one version of the story of the kṣatrīya. The other version is closely connected to their Central Asian home, located in present-day northern Afghanistan, eastern Turkmenistan, southern Uzbekistan and western Tajikistan. Centred on the upper Amu Darya (Oxus River) it emerged later, around 2,300–1,700 BCE, as the Oxus civilization, now called the Bactria-Margiana Archaeological Complex.Something interesting suggests itself at this point. Could the kṣatrīya from their landlocked home in Central Asia have headed south in search of a maritime port ? Uttarāpath going from Gandhār to Magadh branched off at Mathurā to connect to Kāṭhīyāvāḍ, a sheltered harbour. We know that later a regular exchange of people and goods happened between Gandhār and Bactria-Margiana Archaeological Complex. [Neelis, 2011 : Early Buddhist Transmission and Trade Networks, 185]

description: We study S-matrix correlations for random matrix ensembles with a Hamiltonian which is the sum of a given deterministic part and of a random matrix with a Gaussian probability distribution. Using Efetov's supersymmetry formalism, we show that, in the limit of infinite matrix size of the Hamiltonian, correlation functions of S-matrix elements are universal on the scale of the local mean level spacing: the dependence of the deterministic part enters into these correlation functions only through the average S-matrix and the average level density. This statement applies to each of the three symmetry classes (orthogonal, unitary, and symplectic).

description: All known solutions of the Dirac equation describing states of electrons endowed with angular momentum are very far from our notion of the electron as a spinning charged bullet because they are not localized in the direction of propagation. We present here analytic exact solutions, eigenstates of the total angular momentum component $M_z$, that come very close to this notion. These new solutions of the Dirac equation have also intricate topological properties similar to the hopfion solutions of the Maxwell equations.

description: Previous studies have discovered arboreal pollen in non-forested areas on the Tibetan Plateau, which are mostly anemophilous type and regarded as a result of the Asian summer monsoon. However, the relationship between the spatial distribution of wind-pollinated pollen and monsoon has seldom been illustrated quantitatively. Here, we used 676 surface samples (647 compiled, 29 new samples) to examine the characteristics of the spatial distribution patterns of 13 anemophilous pollen taxa on the southeastern Tibetan Plateau, by employing the spatial interpolation technique. Then, we quantified the correlation between the distributions of these taxa and monsoon wind via mantel test. The results show that the anemophilous pollen represents at least half percentage of the total pollen assemblages in most areas of the study region. Anemophilous tree pollen mainly distributes in the south and southeastern part, while anemophilous non-tree pollen does in the opposite and perpendicular direction. The distributional pattern of non-anemophilous pollen reflects that their corresponding plants most likely constitute the understory components of different forests or the minorities of non-forests communities. Mantel tests indicate that the anemophilous tree pollen has a highest correlation with the Asian summer monsoon. Anemophilous pollen, overall pollen assemblages and anemophilous pollen with air sacs have higher correlations with summer monsoon. Contrarily, non-anemophilous pollen has relatively weak correlation. Furthermore, we found that the relationships between various pollen groups or separate taxon and the Asian summer monsoon are dependent on sample types. The lake sediment surface samples had the strongest signal of the Asian summer monsoon among the different sample types. Our findings provide the strong evidence of the Asian summer monsoon influencing the pollen distribution patterns. More importantly, the quantification of this correlation between anemophilous tree pollen and the Asian summer monsoon offers the fundamentally theoretical basis of reconstructing paleo-monsoon by the proxy of windborne pollen taxa.

description: Using a surgically induced varicocele rat model, we show here strong evidence that the misfolded/unfolded protein response that is part of the stress response of the endoplasmic reticulum (ER) is activated in the varicocele testis (VCL), leading to the induction of apoptosis. To support this hypothesis, it is observed that the spliced variant of the X-box protein 1 (XBP1s), resulting from the activation of the inositol-requiring enzyme 1 (IRE1) membrane sensor, is significantly more represented in VCL testicular extracts. The activation of the IRE1/XBP1s pathway is also supported by the observation that the VCL testes show an increase phosphorylation of the c-Jun-kinase (JNK) known to be one intermediate of this pathway and an increased level of caspase-3, the terminal apoptotic effector, partly explaining the apoptotic status of the VCL testis. We show here that the UPR/ER response is most likely activated in the VCL testis as evidenced by the engagement of the IRE1/JNK/XBP1s pathway.

description: The full spectrum of transfer matrices of the general eight-vertex model on a square lattice is obtained by numerical diagonalization. The eigenvalue spacing distribution and the spectral rigidity are analyzed. In non-integrable regimes we have found eigenvalue repulsion as for the Gaussian orthogonal ensemble in random matrix theory. By contrast, in integrable regimes we have found eigenvalue independence leading to a Poissonian behavior, and, for some points, level clustering. These first examples from classical statistical mechanics suggest that the conjecture of integrability successfully applied to quantum spin systems also holds for classical systems.
