Abstract:
Western tubenose gobies were captured for the first time in France in the Rhine River in September 2007. This species, originating from the Ponto-Caspian basin and considered as invasive in many countries, has colonised the Rhine drainage using the Rhine-Main-Danube canal.

Upon formation, radiative polaritons in thin oxide films or crystals emit radiation to the surrounding space. This radiation is confined in a small range of the microwave to far-infrared region of the electromagnetic spectrum, independently of the oxide chemistry. This work shows that the low-frequency radiation is blackbody radiation associated with a temperature directly related to the boson character of the radiative polaritons and to their amount. The proximity of this temperature to absolute zero Kelvin explains the confinement of the frequency. This phenomenon is named polariton evaporation.

This study reports
five years of a school readiness intervention called “HABLA” (Home Based Activities
Building Language Acquisition), designed to increase and enrich speech and
literacy activities in the homes of economically and educationally disadvantaged
Latino families with children between the age of 2 and 4. A team of trained
home visitors provided two years of a 23-week program of visitation in which
they met with parent(s) and child twice weekly. Both years presented a Spanish
language adaptation of the parent-child home program model; home visitors
provide intensive modeling and coaching of non-directive Spanish language use,
conversation, and literacy activities. Administration of the PLS-3 in Spanish
at the onset and culmination of each year of the program indicates significant
increases in receptive and expressive language for each year of visitation (7.8
standard points for the first year, 4.4 for the second) with effect-size r
ranging from .24 to 42. Participants had significantly improved their levels of
oral Spanish skill and scored much higher than a comparison group of
non-treated. A subset of graduates of the two-year program was tested as
kindergarteners; they showed a continued advantage over a comparison group of 18
peers who had not received the intervention. For the graduates, both their
Spanish PLS-3 scores and English PLS-4 scores were significantly higher, and
their parents reported a continued effort to provide literacy experiences at
home. The HABLA participants also showed a clear advantage for an English
language test of phonological awareness, one of the strongest predictors of
school success.

The Seebeck coefficient S is a temperature- and material-dependent
property, which linearly and causally relates the temperature difference △T between the “hot” and “cold” junctions of a
thermoelectric power generator (TEC-PG) to the voltage difference△V. This phenomenon is the Seebeck effect (SE), and
can be used to convert waste heat into usable energy. This work investigates
the trends of the effective voltage output △V(t) and effective Seebeck coefficient S'(t) versus several hours of activity of a solid
state TEC-PG device. The effective Seebeck coefficientS'(t) here is related to a device, not just to a
material’s performance. The observations are pursued in an insulated
compartment in various geometrical and environmental configurations. The
results indicate that the SE does not substantially depend on the geometrical
and environmental configurations. However, the effective Seebeck coefficientS'(t) and the produced effective

Abstract:
We consider the extremal limit of a black hole geometry of the Reissner-Nordstrom type and compute the quantum corrections to its entropy. Universally, the limiting geometry is the direct product of two 2-dimensional spaces and is characterized by just a few parameters. We argue that the quantum corrections to the entropy of such extremal black holes due to a massless scalar field have a universal behavior. We obtain explicitly the form of the quantum entropy in this extremal limit as function of the parameters of the limiting geometry. We generalize these results to black holes with toroidal or higher genus horizon topologies. In general, the extreme quantum entropy is completely determined by the spectral geometry of the horizon and in the ultra-extreme case it is just a determinant of the 2-dimensional Laplacian. As a byproduct of our considerations we obtain expressions for the quantum entropy of black holes which are not of the Reissner-Nordstrom type: the extreme dilaton and extreme Kerr-Newman black holes. In both cases the classical Bekenstein-Hawking entropy is modified by logarithmic corrections.

Abstract:
We demonstrate that charged null particles can be infinitely blue\-shifted in a Kerr-Newman spacetime. The surface of infinite blueshift can be outside of the ergosphere in a Kerr-Newman spacetime, and outside of the outer event horizon for a Reissner-Nordstrom spacetime. Implications for extensions of the standard model which incorporate charged neutrinos are discussed.

Abstract:
We consider the behaviour of a quantum scalar field on three-dimensional Euclidean backgrounds: Anti-de Sitter space, the regular BTZ black hole instanton and the BTZ instanton with a conical singularity at the horizon. The corresponding heat kernel and effective action are calculated explicitly for both rotating and non-rotating holes. The quantum entropy of the BTZ black hole is calculated by differentiating the effective action with respect to the angular deficit at the conical singularity. The renormalization of the UV-divergent terms in the action and entropy is considered. The structure of the UV-finite term in the quantum entropy is of particular interest. Being negligible for large outer horizon area $A_+$ it behaves logarithmically for small $A_+$. Such behaviour might be important at late stages of black hole evaporation.

Abstract:
We apply the method of conical singularities to calculate the tree-level entropy and its one-loop quantum corrections for a charged Kerr black hole. The Euclidean geometry for the Kerr-Newman metric is considered. We show that for an arbitrary periodization in Euclidean space there exists a conical singularity at the horizon. Its $\delta$-function like curvatures are calculated and are shown to behave similar to the static case. The heat kernel expansion for a scalar field on this conical space background is derived and the (divergent) quantum correction to the entropy is obtained. It is argued that these divergences can be removed by renormalization of couplings in the tree-level gravitational action in a manner similar to that for a static black hole.

Abstract:
We consider two different forms for a relativistic version of a linear restoring force. The pair comes from taking Hooke's law to be the force appearing on the right of the relativistic expressions: dp/dt or dp/dtau . Either formulation recovers Hooke's law in the non-relativistic limit. In addition to these two forces, we introduce a form of retardation appropriate for the description of a linear (in displacement) force arising from the interaction of a pair of particles with a relativistic field. The procedure is akin to replacing Coulomb's law in E&M with a retarded form (the first correction in the full relativistic case). This retardation leads to the expected oscillation, but with amplitude growth in both its relativistic and non-relativistic incarnations.

Abstract:
We show that a point particle moving in space-time on entwined-pair paths generates Schroedinger's equation in a static potential in the appropriate continuum linit. This provides a new realist context for the Schroedinger equation within the domain of classical stochastic processes. It also suggests that self-quantizing systems may provide considerable insight into conventional quantum mechanics.
