Understanding the Fate of H2S Injected in Basalts by Means of Time-Domain Induced Polarization Geophysical Logging

To help meet emission standards, hydrogen sulfide (H2S) from geothermal production may be injected back into the subsurface, where basalt offers, in theory, the capacity to mineralize H2S into pyrite. Ensuring the viability of this pollution mitigation technology requires information on how much H2S is mineralized, at what rate and where. To date, monitoring efforts of field-scale H2S reinjection

Polarization charge of particles near threshold due to the coupling to shape oscillations

It is shown that the isoscalar strength in the energy region just above the low energy threshold, which is created by exciting particles to the continuum in nuclei far from β-stability lines, can be reduced by the attractive coupling to isoscalar shape oscillations. This is in contrast to the well known fact that in β-stable nuclei low lying isoscalar particle hole strengths are always increased b

Threats, emotional reactions and affective polarization

In this chapter, we discuss threats and emotions as drivers of affective polarization. We base our discussion on Social Identity Theory and Intergroup Threat Theory, with the basic idea that threats posed by other social groups strengthen intergroup differentiation. Drawing on intergroup threat theory, we argue that when individuals perceive an outgroup threatens the ingroup, they will react with

Cichlids respond to conspecific sounds but females exhibit no phonotaxis without the presence of live males

Many fish species are able to produce sounds, which are often associated with courtship. In an earlier study, we showed for the Lake Victoria cichlid Pundamilia nyererei that females prefer to associate with a male with sound over a male without sound. As a follow-up to this earlier finding, we here investigated whether playback of conspecific sounds is sufficient to attract females in the absence

“Not a Sight, but a Sound” : Listening in E. M. Forster’s A Passage to India

This article examines what happens when we listen to E. M. Forster’s A Passage to India (1924), suggesting that sound has several important functions in the novel, which relate both to the conflicts between the different cultural groupings and to the existential questions that underpin the plot. In making a distinction both between eye and ear, and then between hearing and listening, the article a

Honeybee navigation: critically examining the role of the polarization compass

Although it is widely accepted that honeybees use the polarized-light pattern of the sky as a compass for navigation, there is little direct evidence that this information is actually sensed during flight. Here, we ask whether flying bees can obtain compass cues derived purely from polarized light, and communicate this information to their nest-mates through the 'waggle dance'. Bees, from an obser

Sound propagation over inhomogeneous ground including a sound velocity profile

The atmospheric profile whose sound speed varies linearly with height is simple in concept, but leads to complications when solving for the sound pressure. Its effects are commonly approximated by a similar profile whose squared refractive index is a linear function of height. In this paper, the validity of the approximation has been examined for sound propagation above an impedance ground and a c

Challenges and some new directions in channel coding

Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: spatially coupled Low-Density Parity-Check (LDPC) codes, non-binary LDPC codes, and polar coding.

Two-photon excitation in fluorescence polarization receptor-ligand binding assay

Fluorescence polarization is one of the most commonly used homogeneous assay principles in drug discovery for screening of potential lead compounds. In this article, the fluorescence polarization technique is combined with 2-photon excitation of fluorescence. Theoretically, the use of 2-photon excitation of fluorescence increases the volumetric sensitivity and polarization contrast of fluorescence

An unexpected advantage of whiteness in horses: the most horsefly-proof horse has a depolarizing white coat

White horses frequently suffer from malign skin cancer and visual deficiencies owing to their high sensitivity to the ultraviolet solar radiation. Furthermore, in the wild, white horses suffer a larger predation risk than dark individuals because they can more easily be detected. In spite of their greater vulnerability, white horses have been highly appreciated for centuries owing to their natural

Modular Polarization-Engineered Optical Phased Arrays for Optical Wireless Indoor Networks

The growing passion for indoor optical wireless networks reflects their immense capability to deliver consistent high-quality data connectivity across diverse indoor environments. This study examines how polarization can be engineered to enhance near-field beam focusing in optical wireless indoor networks using a modular clustered optical phased array aperture. The aperture follows a ceiling-mount

Impact of SM parameters and of the vacua of the Higgs potential in gravitational waves detection

In this work we discuss two different phases of a complex singlet extension of the Standard Model (SM) together with an extension that also includes new fermion fields, in particular, a Majoron model equipped with an inverse seesaw mechanism. All considered scenarios contain a global U(1) symmetry and allow for first-order phase transitions while only two of them are strong enough to favour the de
