The Berry-Keating operator on $L^2(\rz_>,\ud x)$ and on compact quantum graphs with general self-adjoint realizations

description: The Berry-Keating operator $H_{\mathrm{BK}}:= -\ui\hbar(x\frac{\ud\phantom{x}}{\ud x}+{1/2})$ [M. V. Berry and J. P. Keating, SIAM Rev. 41 (1999) 236] governing the Schrödinger dynamics is discussed in the Hilbert space $L^2(\rz_>,\ud x)$ and on compact quantum graphs. It is proved that the spectrum of $H_{\mathrm{BK}}$ defined on $L^2(\rz_>,\ud x)$ is purely continuous and thus this quantization of $H_{\mathrm{BK}}$ cannot yield the hypothetical Hilbert-Polya operator possessing as eigenvalues the nontrivial zeros of the Riemann zeta function. A complete classification of all self-adjoint extensions of $H_{\mathrm{BK}}$ acting on compact quantum graphs is given together with the corresponding secular equation in form of a determinant whose zeros determine the discrete spectrum of $H_{\mathrm{BK}}$. In addition, an exact trace formula and the Weyl asymptotics of the eigenvalue counting function are derived. Furthermore, we introduce the "squared" Berry-Keating operator $H_{\mathrm{BK}}^2:= -x^2\frac{\ud^2\phantom{x}}{\ud x^2}-2x\frac{\ud\phantom{x}}{\ud x}-{1/4}$ which is a special case of the Black-Scholes operator used in financial theory of option pricing. Again, all self-adjoint extensions, the corresponding secular equation, the trace formula and the Weyl asymptotics are derived for $H_{\mathrm{BK}}^2$ on compact quantum graphs. While the spectra of both $H_{\mathrm{BK}}$ and $H_{\mathrm{BK}}^2$ on any compact quantum graph are discrete, their Weyl asymptotics demonstrate that neither $H_{\mathrm{BK}}$ nor $H_{\mathrm{BK}}^2$ can yield as eigenvalues the nontrivial Riemann zeros. Some simple examples are worked out in detail.

Possible mechanisms for initiating macroscopic left-right asymmetry in developing organisms

description: How might systematic left-right (L/R) asymmetry of the body plan originate in multicellular animals (and plants)? Somehow, the microscopic handedness of biological molecules must be brought up to macroscopic scales. Basic symmetry principles suggest that the usual "biological" mechanisms -- diffusion and gene regulation -- are insufficient to implement the "right-hand rule" defining a third body axis from the other two. Instead, on the cellular level, "physical" mechanisms (forces and collective dynamic states) are needed involving the long stiff fibers of the cytoskeleton. I discuss some possible scenarios; only in the case of vertebrate internal organs is the answer currently known (and even that is in dispute).

Practical implementation and error bounds of integer-type general algorithm for higher order differential equations

description: In our preceding paper, we have proposed an algorithm for obtaining finite-norm solutions of higher-order linear ordinary differential equations of the Fuchsian type [\sum_m p_m (x) (d/dx)^m] f(x) = 0 (where p_m is a polynomial with rational-number-valued coefficients), by using only the four arithmetical operations on integers, and we proved its validity. For any nonnegative integer k, it is guaranteed mathematically that this method can produce all the solutions satisfying \int |f(x)|^2 (x^2+1)^k dx < \infty, under some conditions. We materialize this algorithm in practical procedures. An interger-type quasi-orthogonalization used there can suppress the explosion of calculations. Moreover, we give an upper limit of the errors. We also give some results of numerical experiments and compare them with the corresponding exact analytical solutions, which show that the proposed algorithm is successful in yielding solutions with high accuracy (using only arithmetical operations on integers).

The reaction of silver with cyanide solutions under oxygen pressure
Creators: name: Deitz, George Albert
Publisher: name: University of British Columbia
Year: 2012

description: An investigation of the kinetics of dissolution of silver in NaCN solutions in the presence of gaseous oxygen under pressure has been carried out with a view to establishing the reactions involved and the factors influencing the rate. The reaction studies were made using a pressure vessel and the reaction was followed by periodic sampling and analysis of the solution. The variables investigated included cyanide concentration, oxygen pressure, temperature and the presence of metal hydroxides in the solution. Linear, zero order reaction rate curves were generally obtained. The rate of dissolution of silver was found to increase linearly with increasing cyanide concentration and level off at a value which was proportional to the oxygen pressure. At constant cyanide concentration, a similar dependence of the rate on oxygen pressure was observed. The apparent activation energy of the reaction is 2400 cal./gm-mole. The results indicate that the rate of reaction is determined principally by the diffusion of the reactants in solution to the silver surface. At low cyanide concentrations, when oxygen is present in excess, the rate is controlled by the diffusion of cyanide ions. Conversely, when cyanide is in excess, the diffusion of oxygen is rate controlling. The principle reaction appears to be: 2Ag + 4NaCN + O₂ + 2H₂O → 2NaAg(CN)₂ + 2NaOH + H₂O₂ which is in agreement with the findings of previous investigators. The reaction rate was found to decrease with increasing pH on addition of metal hydroxide salts to the solution. In the case of KOH, the rate decrease is believed to be due to the lowered solubility of oxygen and a lowered potential for its reduction. The effect of Ca(OH)₂ and Ba(OH)₂ in lowering the rate is more marked. This appears to be due to the formation of an insoluble peroxide coating on the silver surface, which was identified by x-ray diffraction measurements. The thermodynamic properties of silver in dilute aqueous solutions, the suggested possible dissolution reactions and the effect of the cyanide ion concentration on the thermodynamic properties of these reactions are presented and discussed in the form of potential-pH diagrams, as developed by Pourbaix.
Unconventional quantum criticality emerging as a new common language of transition-metal compounds, heavy-fermion systems, and organic conductors

description: We analyze and overview several different unconventional quantum criticalities. One origin of the unconventionality is the proximity to first-order transitions. The border between the first-order and continuous transitions is described by a quantum tricritical point (QTCP) for symmetry-breaking transitions. One of the characteristic features is the concomitant divergence of order-parameter and uniform fluctuations in contrast to the conventional quantum critical point (QCP). Several puzzling non-Fermi-liquid properties are referred to be accounted for as in the cases of YbRh2Si2, CeRu2Si2 and beta-YbAlB4. Another more dramatic unconventionality appears in this case for topological transitions such as metal-insulator and Lifshitz transitions. This border, the marginal quantum critical point (MQCP), belongs to an unprecedented universality class with diverging uniform fluctuations at zero temperature. The MQCP has a unique feature by a combined character of symmetry-breaking and topological transitions. The theoretical results are supported by experimental indications for V2-xCrxO3 and an organic conductor kappa-(ET)2Cu[N(CN)2]Cl. Identifying topological transitions also reveals how non-Fermi liquid appears as a phase in metals. The theory also accounts for the criticality of a metamagnetic transition in ZrZn2, by interpreting it as an interplay of Lifshitz transition and correlation effects. We discuss common underlying physics in these examples.

description: In commentary driving, drivers verbalise their observations, assessments and intentions. By speaking out their thoughts, both learning and expert drivers are able to create a better understanding and awareness of their surroundings. In the intelligent vehicle context, automated driving commentary can provide intelligible explanations about driving actions, thereby assisting a driver or an end-user during driving operations in challenging and safety-critical scenarios. In this paper, we conducted a field study in which we deployed a research vehicle in an urban environment to obtain data. While collecting sensor data of the vehicle's surroundings, we obtained driving commentary from a driving instructor using the think-aloud protocol. We analysed the driving commentary and uncovered an explanation style; the driver first announces his observations, announces his plans, and then makes general remarks. He also makes counterfactual comments. We successfully demonstrated how factual and counterfactual natural language explanations that follow this style could be automatically generated using a transparent tree-based approach. Generated explanations for longitudinal actions (e.g., stop and move) were deemed more intelligible and plausible by human judges compared to lateral actions, such as lane changes. We discussed how our approach can be built on in the future to realise more robust and effective explainability for driver assistance as well as partial and conditional automation of driving functions.

Assessing the Effectiveness of the K to 12 Program: Examining the Impact of Senior High School Implementation in the Philippines
Creators: name: Deysolong, Josephine
Publisher: name: figshare
Year: 2023
Subjects: Curriculum and pedagogy not elsewhere classified

description: The K to 12 program, implemented in the Philippines with the addition of two years of senior high school, aimed to improve the quality of education and equip students with relevant skills for higher education and the workforce. This article examines the effectiveness of the program since the implementation of senior high school and evaluates its advantages and disadvantages. The advantages include enhanced readiness for higher education, skills development, global competitiveness, and workforce readiness. However, challenges such as transitional difficulties, increased financial burden, limited job opportunities, and the risk of brain drain need to be addressed. To ensure the program's success, adequate resources, financial assistance, and collaboration between educational institutions and industries are necessary. The K to 12 program represents a long-term investment in the future of the Philippine education system, with the potential to produce a more competitive and well-prepared generation of graduates.

The Family Welfare Bureau of Greater Vancouver : its origins and development, 1927 to 1952
Creators: name: Mitchell, Robert James Gordon

description: The Family Welfare Bureau of Greater Vancouver has now been in existence for twenty-five years, and it is the purpose of this study to trace its development from its origins in the recommendations of the British Columbia Child Welfare Survey of 1927, to the present day. Material for this purpose was collected from the minutes of the Executive Board of the Bureau, 1927 to 1952; the annual reports of the Director for the same years; personal interviews with the Director and other staff members; other related records and literature of the agency; and numerous pamphlets and publications of the Family Service Association of America. This latter body is a standard-setting association of family agencies to which the Bureau has belonged from its inception. In the course of its life, the agency has been faced with many unforeseen difficulties, the more drastic of these being the depression years of the 1930's and the war years of 1939 to 1945. These two periods of economic and social stress are reflected clearly in the workload of the agency, and it would have been understandable had this new organization strayed from its original objective, which was to do family casework. An appraisal of the work of the Bureau shows clearly, however, that: (1) it has filled a definite need within the overall framework of agencies in the community, and (2) it has steadfastly maintained its original purpose of providing family casework, services. In addition, (3) it has constantly striven to improve its standards of professional competence, and (4) it has followed the traditional role of private agencies in experimenting in the provision of new services. The record also indicates that, even though the community is showing increasing acceptance of casework services, continued and careful studies will have to be made to determine the most effective way of interpreting to the public, on which the Bureau depends for its financing, the meaning and value of these non-material services.

Per la prima volta, gli astronomi hanno potuto seguire direttamente il moto di un pianeta extrasolare che si muove da un lato all'altro della sua stella. Il pianeta compie l’orbita più breve tra tutti i pianeti extrasolari direttamente osservati, molto vicino alla sua stella madre come Saturno lo è con il Sole.

description: We investigate the n-variable real functions G that are solutions of the Chisini functional equation F(x)=F(G(x),...,G(x)), where F is a given function of n real variables. We provide necessary and sufficient conditions on F for the existence and uniqueness of solutions. When F is nondecreasing in each variable, we show in a constructive way that if a solution exists then a nondecreasing and idempotent solution always exists. We also provide necessary and sufficient conditions on F for the existence of continuous solutions and we show how to construct such a solution. We finally discuss a few applications of these results.

On the nodal sets of toral eigenfunctions

description: We study the nodal sets of eigenfunctions of the Laplacian on the standard d-dimensional flat torus. The question we address is: Can a fixed hypersurface lie on the nodal sets of eigenfunctions with arbitrarily large eigenvalue? In dimension two, we show that this happens only for segments of closed geodesics. In higher dimensions, certain cylindrical sets do lie on nodal sets corresponding to arbitrarily large eigenvalues. Our main result is that this cannot happen for hypersurfaces with nonzero Gauss-Kronecker curvature. In dimension two, the result follows from a uniform lower bound for the L^2-norm of the restriction of eigenfunctions to the curve, proved in an earlier paper. In high dimensions we currently do not have this bound. Instead, we make use of the real-analytic nature of the flat torus to study variations on this bound for restrictions of eigenfunctions to suitable submanifolds in the complex domain. In all of our results, we need an arithmetic ingredient concerning the cluster structure of lattice points on the sphere. We also present an independent proof for the two-dimensional case relying on the "abc-theorem" in function fields.

description: Flower like zinc oxide nanoparticles have been synthesized and the effects of their aqueous suspensions at 200–1000 mg/L on seed germination and seedlings of Triticum aestivum have been investigated. When treated with suspensions of zinc oxide nanoparticles at concentrations of 200–1000 mg/L, germination was reduced to 45% and photosynthetic pigments (chlorophyll a, b, and carotenoids) were also depressed. Enzymatic and non-enzymatic plant defense mechanisms were adversely affected at the maximum concentration. Abnormalities in the concentrations of proline, malondialdehyde, phenols and flavonoids were observed in the roots and shoots of plant due to the zinc oxide nanoparticles at different concentrations.

On the Exel crossed product of topological covering maps

description: For dynamical systems defined by a covering map of a compact Hausdorff space and the corresponding transfer operator, the associated crossed product $C^*$-algebras $\cros$ introduced by Exel and Vershik are considered. An important property for homeomorphism dynamical systems is topological freeness. It can be extended in a natural way to in general non-invertible dynamical systems generated by covering maps. In this article, it is shown that the following four properties are equivalent: the dynamical system generated by a covering map is topologically free; the canonical imbedding of $C(X)$ into $\cros$ is a maximal abelian $C^*$-subalgebra of $\cros$; any nontrivial two sided ideal of $\cros$ has non-zero intersection with the imbedded copy of $C(X)$; a certain natural representation of $\cros$ is faithful. This result is a generalization to non-invertible dynamics of the corresponding results for crossed product $C^*$-algebras of homeomorphism dynamical systems.

description: We exploit a novel approximation scheme to obtain a new and compact formula for the parameters underlying coherent-state control of the evolution of a pair of entangled two-level systems. It is appropriate for long times and for relatively strong external quantum control via coherent state irradiation. We take account of both discrete-state and continuous-variable degrees of freedom. The formula predicts the relative heights of entanglement revivals and their timing and duration.
