Opis:
Researchers in the field of instructed second language acquisition have been examining the issue of how learners interact with input by conducting research measuring particular kinds of instructional interventions (input-oriented and meaning-based). These interventions include such things as input flood, textual enhancement and processing instruction. Although the findings are not completely conclusive on whether these instructional interventions have an impact on acquisition, it is clear that we have witnessed a shift in the field from the original question “Does instruction make a difference?” to the more specific question “Does manipulating input make a difference?” In this article, the key classroom-based research conducted to measure the relative effects of different types of enhancement and manipulation is reviewed. Three main research foci are considered: (a) research measuring the effects of saturating the input with the target form (input flood), (b) research measuring the effects of different types of textual enhancements to draw learners’ attention to the target form, and (c) research measuring input restructuring to improve interpretation and processing of target forms or structures (processing instruction).

Opis:
Microscopic technology has recently flourished, allowing unparalleled viewing of microscopic elements invisible to the normal eye. Still, the existence of unavoidable constraints led on many occasions to have low contrast scanning electron microscopic (SEM) images. Thus, a noncomplex multiphase (NM) algorithm is proposed in this study to provide better contrast for various SEM images. The developed algorithm contains the following stages: first, the intensities of the degraded image are modified using a two-step regularization procedure. Next, a gamma-corrected cumulative distribution function of the logarithmic uniform distribution approach is applied for contrast enhancement. Finally, an automated histogram expansion technique is used to redistribute the pixels of the image properly. The NM algorithm is applied to natural-contrast distorted SEM images, as well as its results are compared with six algorithms with different processing notions. To assess the quality of images, three modern metrics are utilized, in that each metric measures the quality based on unique aspects. Extensive appraisals revealed the adequate processing abilities of the NM algorithm, as it can process many images suitably and its performances outperformed many available contrast enhancement algorithms in different aspects.

Opis:
Human enhancement affects all members of society and is thus closely linked to issues of social justice: up to now, the promises and perils of enhancement are usually only known to, and thus used, by few members of society. This can lead to individual competitive advantages that create or widen social gaps. Broad public information is, therefore, key to ensure that enhancement does not conflict with the principle of equality of opportunities. As possible means of public information, literature and films are able to counter such possible social injustice, which is why they may be allotted a central role in the ethical debates on human enhancement. Two aspects will be considered in this regard: 1) enhancement in art and 2) through art. 1) The extent to which artistic depictions and public information and perceptions of enhancement may be intertwined will be illustrated by two examples where both texts and their accompanying paratexts had a particular bearing on the public debate on enhancement: the film Gattaca of 1997 and the novel Never let me go (2005) by Nobel laureate Kazuo Ishiguro. 2) The second part of the paper is dedicated to the question of how far enhancing selected groups of society may contribute to a greater common good and which potentials art can offer in this regard. Three groups of persons will be taken into account: 1) clinical ethics committees, 2) physicians, and 3) patients.

Opis:
In this article I discuss one of the most significant areas of bioethical interest, which is the problem of moral enhancement. Since I claim that the crucial issue in the current debate on human bioenhancement is the problem of agency, I bring out and examine the conditions of possibility of selfunderstanding, acting subjects attributing responsible authorship for their actions to themselves. I shall argue that the very idea of moral enhancement, properly understood, fails to justify the claims that enhancing the “biological” factor that plays a part in the process of making moral choices, whether through biomedical or genetic interventions, will actually increase the probability of having “morally better future motives”.

Opis:
A metamaterial in the form of a periodic lattice of split-ring resonators on a GaAs/AlGaAs heterostructure was numerically studied at terahertz frequencies. A finite-difference time-domain algorithm was applied to calculate distribution of the electromagnetic field in the layer positioned at 100 nm below the heterostructure surface where a two-dimensional electron gas typically resides in real structures. The results allowed to determine the resonant frequencies of the metamaterial as well as an enhancement factor of the electric field as a function of the period of the metamaterial's lattice.

Opis:
This paper proposes a speech enhancement method using the multi-scales and multi-thresholds of the auditory perception wavelet transform, which is suitable for a low SNR (signal to noise ratio) environment. This method achieves the goal of noise reduction according to the threshold processing of the human ear’s auditory masking effect on the auditory perception wavelet transform parameters of a speech signal. At the same time, in order to prevent high frequency loss during the process of noise suppression, we first make a voicing decision based on the speech signals. Afterwards, we process the unvoiced sound segment and the voiced sound segment according to the different thresholds and different judgments. Lastly, we perform objective and subjective tests on the enhanced speech. The results show that, compared to other spectral subtractions, our method keeps the components of unvoiced sound intact, while it suppresses the residual noise and the background noise. Thus, the enhanced speech has better clarity and intelligibility.

Opis:
Localized Surface Plasmon Resonance (LSPR) mediated electromagnetic field enhancement play a vital role in enhancing the performance of bio-molecular sensors, photovoltaic cells and Raman spectroscopy (e.g., in SERS) etc., to name only a few. It is now well established that the field amplification factor (mode squared field) ~106 for spherical shaped plasmonic nanoparticle dimers is significantly higher than the amplification factor of a monomer which is ~103. In this work, a theoretical and semi-analytical approach based on multipole spectral expansion is used to investigate the electric field enhancement in the gap region of spherical nanoparticle dimers of Al, Rh, Ag, and Au. The dimer exhibit rich spectra compared to its isolated counterpart. For example, in contrast to a monomer, the dimer spectra consists of multiple resonant peaks which can be fine tuned by varying particle size and/or inter-particle separation. Moreover, the enhancement in dimer is several orders higher than that in monomers. Rich spectral features in dimer spectra arise from the interaction between particle plasmons of constituent NPs and their hybridization, which results in the splitting of plasmonic energy levels. We carry out, systematic investigation of these systems to quantify the effect of particle size, interparticle separation and metal type (Al, Ag, Au, Rh) on electric field enhancement.

Opis:
The growing popularity of so-called cognitive enhancement technologies raises questions about their impact on the sphere of individual legal responsibility. This article examines the issue of whether, in a situation where a surgeon, prone to making a fatigue-related medical error, refuses to undergo a safe cognitive enhancement before surgery, the surgeon can be attributed liability for damages. The answer to this question is negative, however, as indicated in the article, the impossibility of attributing damages is a result of (1) the lack of professional guidelines requiring doctors to undergo cognitive enhancement; (2) the lack of scientific evidence that the use of such measures results in the elimination of fatigue and reduces the risk of error. As a result, the negative answer to the analyzed question is not determined by the solution of the model of liability for damages adopted in Polish law, but rather by the current state of research on cognitive improvement. This gives the analysis a universal character and makes it possible to relate the method adopted in it to new results of research on means of cognitive enhancement if any.

Opis:
The exponential growth of technological advancements creates an environment in which the traditionally conceived cognitive enhancement – education – must constantly redefine itself in the face of the invasive presence of A.I., the social media and various biotechnologies that strive to augment the effect-oriented performance. Whereas on the conceptual level there is a visible shift from the static to flow-modelled education, and the rising trend to invest in the skills like flexibility and creativity, not many of emerging technologies are seriously considered as educational tools. The paper looks into the varieties of cognitive enhancement within educational context. Of major concern are the already available technologies of collective intelligence and nootropics, as well as experimental dowloadable learning. I review the problems occasioned by these technologies, as well as the existing solutions, which tend to incorporate rather than exclude the possibilities of radical cognitive enhancement.
