Effect of surface nanostructure on temperature programmed reaction spectroscopy: First-principles kinetic Monte Carlo simulations of CO oxidation at RuO2(110)

Using the catalytic CO oxidation at RuO2(110) as a showcase, we employ first-principles kinetic Monte Carlo simulations to illustrate the intricate effects on temperature programmed reaction spectroscopy data brought about by the mere correlations between the locations of the active sites at a nanostructured surface. Even in the absence of lateral interactions, this nanostructure alone can cause inhomogeneities that cannot be grasped by prevalent mean-field data analysis procedures, which thus lead to wrong conclusions on the reactivity of the different surface species.Comment: 4 pages including 3 figures; related publications can be found at http://www.fhi-berlin.mpg.de/th/th.htm

The contribution of methanol to the 3.4 micron feature in comets

With the advent of improved detectors and improved moderate resolution spectrometers several interesting features have been seen in the infrared spectra of comets. In particular, an emission excess at 3.52 microns was observed in several comets, and has recently been tentatively assigned to the nu 3 band of methanol (CH3OH). Using a developed model it is possible to calculate the relative strengths of the CH3OH features. The 3.52 microns emission strengths were used in a number of comets to retrieve methanol amounts, and the model was used to predict the fraction of the 3.4 micron flux which is contributed by the species. Implications for cometary formation are discussed

Infrared remote sensing of cometary parent volatiles from the ground, air, and space

A balanced view of the present generation of infrared instruments for cometary compositional studies is presented. Ground-based instruments are compared with airborne and spaceborne capabilities. An attempt to give examples of the unique science achievable with each is made, and particular emphasis is on the unique aspects of a dedicated Cometary Composition Telescope in earth orbit for investigating the chemical and structural heterogeneity of the cometary nucleus

Can commitments cause counterpreferential choices?

Commitments are crucial for our lives but there is no consensus on how commitments and preferences relate to each other. In this paper, we present three empirical studies that provide evidence that people sometimes choose a less preferred option when they have made a commitment

A Tachyonic Gluon Mass: Between Infrared and Ultraviolet

The gluon spin coupling to a Gaussian correlated background gauge field induces an effective tachyonic gluon mass. It is momentum dependent and vanishes in the UV only like 1/p^2. In the IR, we obtain stabilization through a positive m^2_{conf}(p^2) related to confinement. Recently a purely phenomenological tachyonic gluon mass was used to explain the linear rise in the q\bar q static potential at small distances and also some long standing discrepancies found in QCD sum rules. We show that the stochastic vacuum model of QCD predicts a gluon mass with the desired properties.Comment: 10 pages LaTeX, 2 figures using eps

Putting Pain in its Proper Place

In a series of articles in this journal, Michael Tye (2002) and Paul Noordhof (2001, 2002) have sparred over the correct explanation of the putative invalidity of the following argument: the pain is in my fingertip; the fingertip is in my mouth; therefore, the pain is in my mouth. Whereas Tye explains the failure of the argument by stating that “pain” creates an intensional context, Noordhof maintains that the “in” in “the pain is in my fingertip” is not spatial, but has state-attributing character. In this paper, we offer a third account, explaining the failure of the argument through state-attributing pragmatic implicatures. Empirical evidence is provided in support of this account

Can the AML/CTF systems be evaluated without better data?

The Anti-Money Laundering regime has been important in harmonizing laws and institutions, and has received global political support. Yet there has been minimal effort at evaluation of how well any AML intervention does in achieving its goals. There are no credible estimates either of the total amount laundered (globally or nationally) nor of most of the specific serious harms that AML aims to avert. Consequently, reduction of these is not a plausible outcome measure. There have been few efforts by country evaluators in the FATF Mutual Evaluation Reports (MERs) to acquire qualitative data or seriously analyze either quantitative or qualitative data. We find that data are relatively unimportant in policy development and implementation. Moreover, the long gaps of about 8 years between evaluations mean that widely used ‘country risk’ models for AML are forced still to rely largely on the 3rd Round evaluations whose use of data was minimal and inconsistent. While the 4th round MERs (2014–2022) have made an effort to be more systematic in the collection and analysis of data, FATF has still not established procedures that provide sufficiently informative evaluations. Our analysis of five recent National Risk Assessments (a major component of the new evaluations) in major countries shows little use of data, though the UK is notably better than the others. In the absence of more consistent and systematic data analysis, claims that countries have less or more effective systems will be open to allegations of ad hoc, impressionistic or politicized judgments. This reduces their perceived legitimacy, though this does not mean that the AML efforts and the evaluation processes themselves have no effects

Anti-money laundering: an inquiry into a disciplinary transnational legal order

This Article enquires into the case of one of the most comprehensive, far-reaching, most deeply penetrating, and most punitive of TLOs: antimoney laundering. Drawing on an intensive study at a moment when its governing norms and methodologies of implementation were undergoing revision and expansion, as well as on observation and participation in AML/CFT activities over three decades, the Article brings rich empirical evidence to bear on two theoretical issues. First, despite its seemingly successful institutionalization, the AML TLO exhibits many deficiencies and imposes extensive costs on the private and public sectors, and harms upon the public. Why doesn’t it fail? Second, the pervasiveness and penetration of the AML TLO indicates it may constitute a particular species of “disciplinary” TLOs. To address these issues, the Article, first, briefly sketches the thirty-year development and workings of the AML TLO; second, considers its benefits, costs, deficiencies and harms; third, confronts the puzzle of its persistence; and, fourth, concludes by arguing that the AML TLO may be distinctive insofar as (1) it has a foundational assumption of recalcitrant actors who must be monitored to reduce social harms which (2) legitimates a pervasive surveillance apparatus that is (3) yoked to punitive criminal institutions and practices which (4) lead to an elaborate repertoire of discipline that (5) has been multiplied to include states, financial institutions (e.g. banks), non-state collective actors such as charities, organized crime families, and individuals such as lawyers, accountants, and everyday participants in their myriads of transactions in an integrated global financial system. Those singular properties may in fact be shared substantially by other TLOs directed at crime. The site of criminal justice thereby encourages a more differentiated understanding of TLOs in 21st century settings
