Recently, Ambainis defined the complexity class P^QMA[log], and motivated its study by showing that the physical task of estimating the expectation value of a local observable against the ground state of a local Hamiltonian is P^QMA[log]-complete. In this paper, we continue the study of P^QMA[log], obtaining the following results. The P^QMA[log]-completeness result of Ambainis requires O(log n)-local observ- ables and Hamiltonians. We show that simulating even a single qubit measurement on ground states of 5-local Hamiltonians is P^QMA[log]-complete, resolving an open question of Ambainis. We formalize the complexity theoretic study of estimating two-point correlation functions against ground states, and show that this task is similarly P^QMA[log]-complete. P^QMA[log] is thought of as \"slightly harder\" than QMA. We justify this formally by exploiting the hierarchical voting technique of Beigel, Hemachandra, and Wechsung to show P^QMA[log] \\subseteq PP. This improves the containment QMA \\subseteq PP from Kitaev and Watrous. A central theme of this work is the subtlety involved in the study of oracle classes in which the oracle solves a promise problem. In this vein, we identify a flaw in Ambainis' prior work regarding a P^UQMA[log]-hardness proof for estimating spectral gaps of local Hamiltonians. By introducing a \"query validation\" technique, we build on his prior work to obtain P^UQMA[log]-hardness for estimating spectral gaps under polynomial-time Turing reductions.","lang":"eng"}]},{"title":"Computing subfields of number fields and applications to Galois group computations","publisher":"Elsevier BV","date_created":"2022-12-22T10:52:18Z","year":"2018","keyword":["Computational Mathematics","Algebra and Number Theory"],"language":[{"iso":"eng"}],"external_id":{"arxiv":["1610.06837 "]},"abstract":[{"lang":"eng","text":"A polynomial time algorithm to find generators of the lattice of all subfields of a given number field was given in van Hoeij et al.

The framework is then used to prove the existence of obstructions arising from conformal symplectic symmetries on the bifurcation behaviour of solutions to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group action by conformal symplectic symmetries has the effect that the flow map cannot degenerate in a direction which is tangential to the action. This imposes restrictions on which singularities can occur in boundary value problems.

The present approach further develops this extension of TVA’s scope by measuring and modeling salience. An empirical measure of salience is achieved by linking different (orientation and luminance) contrasts to a TVA parameter. In the modeling part, the function relating feature contrasts to salience is described mathematically and tested against alternatives by Bayesian model comparison.

All in all, 693 teacher education students participated in an online questionnaire. Students were asked to rate general requirements of their academic programs (e.g., self-discipline) on a 5-point scale in terms of (1) their own abilities and (2) the perceived relevance for their studies. P-E fit was determined by difference scores between abilities and relevance ratings. Academic success was assessed by grades, perceived performance, and study satisfaction. Data were analyzed through structural equation modeling and suggest that academic success is best explained by a match between abilities and demands.

Therefore, we answer two questions. Why does a small group of insurgents believe it can overthrow the government by turning violent, even if the government is clearly superior? And how does a conflict develop into terrorism, a guerilla war, or a major conventional civil war, or is resolved peacefully? We develop a formal model for rebels and government and derive optimal choices. Further, we focus on three elements as important ingredients of a \"destabilization war\". All three of these - large random events, time preference (which we relate to ideology), and choice of duration of fight - are rarely considered in formal conflict theory. We can answer the above two questions using game theory analysis. First, insurgents rise up because they hope to destabilize through permanent challenging attacks. In this context, large randomness is an important ally of rebels. While each individual attack may have a low impact, at some point a large random event could lead to success. Hence, the duration of activities is a constitutive element of this kind of armed conflict. Patience (low time preference), which may reflect rebels' degree of ideological motivation, is crucial. Second, the mode of warfare or the conflict resolutions that develop are generally path-dependent and conditioned on the full set of options (including compromise). Various conditions (level of funding, ease of recruitment, access to weapons) influence different modes of warfare or a peaceful compromise in a complex way."}],"language":[{"iso":"eng"}],"ddc":["040"],"keyword":["terrorism","civil war","conflict duration","game theory","stochastic process","ideology"],"year":"2016","date_created":"2019-04-08T06:45:02Z","title":"An Economic Theory of 'Destabilization War'","type":"working_paper","status":"public","series_title":"Working Papers CIE","user_id":"20801","department":[{"_id":"205"},{"_id":"475"}],"_id":"8836","file_date_updated":"2019-04-08T06:49:16Z","has_accepted_license":"1","jel":["H56","O10","D84","C72","D74"],"citation":{"chicago":"Gries, Thomas, and Claus-Jochen Haake. <i>An Economic Theory of “Destabilization War.”</i> Vol. 95.

In addition, the management of multiple accounts and identities can be very onerous and time consuming for the responsible administrator and therefore expensive for the organization. In order to meet these challenges, firms decide to invest in introducing an Identity and Access Management System (IAMS) that supports the organization by using policies to assign permissions to accounts, groups, and roles. In practice, since various versions of IAMSs exist, it is a challenging task to decide upon introduction of an IAMS. The following study proposes a first attempt of a decision support model for practitioners which considers four alternatives: Introduction of an IAMS with Role-based Access Control RBAC) or without and no introduction of IAMS again with or without RBAC.

Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. This model allows us to align different contributions of literature reviews with their underlying knowledge conversions - thereby building a bridge between the previously largely unconnected fields of literature reviews and epistemology. We evaluate the appropriateness of the model by conducting an empirical analysis of 173 IS literature reviews which were published in 39 pertinent IS journals between 2000 and 2014. Based on this analysis, we derive an epistemological taxonomy of IS literature reviews, which complements previously suggested typologies."}],"status":"public","file":[{"relation":"main_file","content_type":"application/pdf","file_id":"6037","access_level":"open_access","file_name":"ICIS PROCEEDINGS PAPER - Literature Reviews.pdf","file_size":487102,"creator":"hsiemes","date_created":"2018-12-07T11:44:48Z","date_updated":"2018-12-13T15:09:22Z"}],"publication":"International Conference on Information Systems (ICIS)","type":"conference","keyword":["Literature review","Research methods/methodology","Theory of knowledge"],"ddc":["000"],"language":[{"iso":"eng"}],"file_date_updated":"2018-12-13T15:09:22Z","extern":"1","_id":"5618","department":[{"_id":"277"}],"user_id":"61579","year":"2015","citation":{"ieee":"G.
