We extend Jendrol’ and Skupień’s results about the local structure of maps on the 2-sphere: In this paper we show that if a polyhedral map G on a surface M of Euler characteristic χ(M) ≤ 0 has more than 126|χ(M)| vertices, then G has a vertex with ”nearly” non-negative combinatorial curvature. As a corollary of this, we can deduce that path transferability of such graphs are at most 12. keyword...

Deep learning classifiers are known to be inherently vulnerable to manipulation by intentionally perturbed inputs, named adversarial examples. In this work, we establish that reinforcement learning techniques based on Deep Q-Networks (DQNs) are also vulnerable to adversarial input perturbations, and verify the transferability of adversarial examples across different DQN models. Furthermore, we ...

The strategic value of knowledge sharing has long been recognized but valuable competencies are too often locked in one business unit. This paper provides insight into the role of organizational factors in spreading complex bundles of knowledge among business units. A study in a British multinational confirms the importance of knowledge transferability, headquarters' role, the close relationshi...

R factors fi(+) and fi(-), with various combinations of drug-resistance markers and isolated from independent sources, were transduced by phage P1kc in Escherichia coli and by phage P22 in Salmonella typhimurium. Usually the entire R factor was transduced by P1kc in E. coli, as indicated by the absence of segregation of the drug-resistance markers from their conjugal transferability. In contras...

We establish the physical origins of chemical transferability from the perspective of the nearsightedness of electronic matter. To do this, we explicitly evaluate the response of electron density to a change in the system, at constant chemical potential, by computing the softness kernel, [Formula: see text] The softness kernel is nearsighted, indicating that under constant-chemical-potential co...

Tens of Zr inter-atomic potentials (force fields) have been developed to enable atomic-scale simulations alloys. These can provide critical insight in the in-reactor behaviour nuclear fuel cladding and structural components exposed, but results are strongly sensitive choice potential. We a comprehensive comparison 13 popular potentials, assess their ability reproduce key physical, mechanical, t...

This systematic review aims to assess the characteristics of, and the clinical and economic evidence provided by, economic evaluations of primary preventive physical exercise interventions, and to analyse their transferability to Germany using recommended checklists. Fifteen economic evaluations from seven different countries met eligibility criteria, with seven of the fifteen providing high ec...

Despite the fact that economic data are of great significance in the assessment of human socioeconomic development, the application of this data has been hindered partly due to the unreliable and inefficient economic censuses conducted in developing countries. The night-time light (NTL) imagery from the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) provides o...

BACKGROUND The Bean plataspid (Megacopta cribraria) (Hemiptera: Pentatomidae), native to Asia, is becoming an invasive species in North America; its potential spread to soybean producing areas in the US is of great concern. Ecological niche modelling (ENM) has been used increasingly in predicting invasive species' potential distribution; however, poor niche model transferability was sometimes r...
