Vertical polyelectrolyte-gated organic field-effect transistors
Get PDFShort-channel, vertically structured organic transistors with a polyelectrolyte as gate insulator are demonstrated. The devices are fabricated using low-resolution, self-aligned, and mask-free photolithography. Owing to the use of a polyelectrolyte, our vertical electrolyte-gated organic field-effect transistors (VEGOFETs), with channel lengths of 2.2 and 0.7 μm, operate at voltages below one volt. The VEGOFETs show clear saturation and switch on and off in 200 μs. A vertical geometry to achieve short-transistor channels and the use of an electrolyte makes these transistors promising candidates for printed logics and drivers with low operating voltage.Original Publication:Jiang Liu, Lars Herlogsson, A Sawadtee, P Favia, M Sandberg, Xavier Crispin, Isak Engquist and Magnus Berggren, Vertical polyelectrolyte-gated organic field-effect transistors, 2010, Applied Physics Letters, (97), , 103303.http://dx.doi.org/10.1063/1.3488000Copyright: American Institute of Physicshttp://www.aip.org
Who Brings Which Peace?
No full textThis study examines the effect of biased versus neutral mediation on the content of peace agreements. The author argues that neutral mediators, who are engaged primarily because of their interest to end the war, will have incentives to hasten the reaching of an agreement to the expense of its quality. By contrast, biased mediators, seeking to protect their protégés, will take care to ensure that there are stipulations in an agreement guaranteeing the interest of their side or use their particular access and leverage to make their side agree to costly concessions. Biased mediation processes are therefore more likely than neutral mediation processes to lead to elaborated institutional arrangements that are generally considered conducive to democracy and durable peace, such as power sharing, third-party security guarantees, and justice provisions. Empirical analysis, covering the 1989-2004 period and building on data from 124 peace agreements, supports these claims.</p

"You Cannot Keep Me": The Shakespearean Artist in Three of Isak Dinesen's Tales
No full textIsak Dinesen’s tale “Tempests” and her collection Winter’s Tales pluralize the titles of The
Tempest and The Winter’s Tale, respectively, but few critics have discussed the author’s
engagement with Shakespeare at length. Both of Dinesen’s source texts thematize the
relationship between art and life, and, in this paper, I consider how “Tempests,” “The Young Man
with the Carnation,” and “A Consolatory Tale” adapt Shakespeare’s dramatic presentation of this
topic into narrative form. “Tempests,” I argue, reintroduces the tension between artistic
production and personal relationships which artists perceive in The Tempest, yet Dinesen adds
her own insight that reflection on this tension can generate new art. I then track hints of both this
tension and Dinesen’s insight in her earlier tales “The Young Man with the Carnation” and “A
Consolatory Tale.” These tales add nuance to her presentation of art and life in “Tempests,” I
note, by depicting the unification of artistic production and personal relationships in a more
compelling way. Along the same lines, and drawing upon Shakespeare’s Winter’s Tale, these
works indicate that art has value because it can reflect its audience’s sense of their current
situation, transform familiar stories, and surprise us in a quasi-supernatural way. I conclude by
suggesting that “A Consolatory Tale” takes these points even further by presenting a related
source of art’s value that Shakespeare’s play does not make explicit: art’s ability to create
sympathy between author and reader

This research discusses the analysis of the implementation of PSAK No. 106 and ISAK No.
120 in the valuation of mineral reserves and its impact on the financial statements of PT Indo
Tambangraya Megah Tbk, a coal mining company in Indonesia since 1987. The company has
management permits for several mining areas that are divided into various stages:
development, production, and closure. The analysis was conducted on the financial
statements, notes to the financial statements, annual reports, and interviews with the
company's management. The results of this research indicate that the company has
appropriately recorded costs related to exploration and development, as well as deferred
exploration and development costs, in accordance with PSAK No. 106 and ISAK No. 120.
However, the author found that there are still many areas determined by the company's
accounting policies that could lead to inconsistencies in the application of these standards
D2O ice on controlled wettability self-assembled alkanethiolate monolayers : Cluster formation and substrate-adsorbate interaction
No full textInfrared reflection-absorption spectroscopy is used to investigate thin (1-200 Angstrom average thickness) overlayers of D2O ice deposited in ultrahigh vacuum on controlled wettability self-assembled monolayers. The monolayers were derived from mixed solutions of HS(CH2)(15)CH3 and HS(CH2)(16)OH, making it possible to examine the whole range of samples from f(OH) = 0.0 to f(OH) 1.0, where f(OH) denotes the molar fraction of OH-terminated thiols in the preparation solution. This paper focuses on the interaction between the ice and the monolayer. It is shown that water molecules do not penetrate into the monolayer but that two types of interaction with the chain-terminating groups occur: hydrogen bond formation with surface hydroxyls and weak dipole-dipole interaction with surface methyls. For surfaces with f(OH) less than 0.3, the latter interaction causes the free OD mode, normally observed at 2729 cm(-1), to shift to 2704 cm(-1), thereby providing a spectral signature feature whose intensity is directly proportional to the relative area of the ice/monolayer interface. Quantitative analysis of the infrared spectra suggests that ice clusters are essentially flat on surfaces with 0.6 less than f(OH) less than 1.0 and become more droplet-like for decreasing f(OH) below 0.6. On f(OH) = 0.0 surfaces, the microscopic clusters display high contact angles (similar to 120 degrees), and full surface coverage does not occur until the average overlayer thickness is 150-200 Angstrom.</p
Disrupting Eating Spaces in Isak Dinesen’s 'Babette’s Feast'
No full textUp until recently, the bilingual tales of Danish author Isak Dinesen have been critically appreciated and discussed mostly in relation to their narrative complexity and dramatic theatricality. Focusing on her well-known story “Babette’s Feast”, this essay draws on Jacques Derrida’s understanding of supplementarity, on feminist insights into embodiment and recent new materialist theories to address, instead, the place of enfleshed materiality in her revisionist articulations of gender and community. It calls attention to how food, as live matter, impacts through the organic process of eating, the subject’s movement in and perception of physical, social and gender spaces, contributing thus to recent scholarly engagement with the significance of corporeality and material agency for her fictions’ sexual and cultural politics. Implicit in her re-assertion of the material, as it is argued, is Dinesen’s sharp critique of the Protestant valorisation of spirit over matter and the masculinist assumptions built into this spatial configuration
Glacier : guided locally constrained counterfactual explanations for time series classification
No full textIn machine learning applications, there is a need to obtain predictive models of high performance and, most importantly, to allow end-users and practitioners to understand and act on their predictions. One way to obtain such understanding is via counterfactuals, that provide sample-based explanations in the form of recommendations on which features need to be modified from a test example so that the classification outcome of a given classifier changes from an undesired outcome to a desired one. This paper focuses on the domain of time series classification, more specifically, on defining counterfactual explanations for univariate time series. We propose Glacier, a model-agnostic method for generating locally-constrained counterfactual explanations for time series classification using gradient search either on the original space or on a latent space that is learned through an auto-encoder. An additional flexibility of our method is the inclusion of constraints on the counterfactual generation process that favour applying changes to particular time series points or segments while discouraging changing others. The main purpose of these constraints is to ensure more reliable counterfactuals, while increasing the efficiency of the counterfactual generation process. Two particular types of constraints are considered, i.e., example-specific constraints and global constraints. We conduct extensive experiments on 40 datasets from the UCR archive, comparing different instantiations of Glacier against three competitors. Our findings suggest that Glacier outperforms the three competitors in terms of two common metrics for counterfactuals, i.e., proximity and compactness. Moreover, Glacier obtains comparable counterfactual validity compared to the best of the three competitors. Finally, when comparing the unconstrained variant of Glacier to the constraint-based variants, we conclude that the inclusion of example-specific and global constraints yields a good performance while demonstrating the trade-off between the different metrics. © The Author(s) 2024.This work was funded in part by the Digital Futures cross-disciplinary research centre in Sweden, and the EXTREMUM collaborative project ( https://datascience.dsv.su.se/projects/extremum.html ).</p
