Coherent Control of Resonance-Mediated Reactions: F + HD

Cross sections resulting from scattering that proceeds via an intermediate resonance are shown to be exceptionally controllable using a coherent superposition of only two intial states. Full quantum computations on F+HD(v=0;j=0,1) --> H+DF, D+HF, which exhibits a resonance in one of the reactive channels, support the formal arguments, showing that control is indeed vast. In this case the ratio of reactive integral cross sections can be altered by a factor of 62 (compared to a noncoherent factor of only 3.3), while the ratio of reactive differential cross sections can be altered by a factor of over 6000 (compared to a noncoherent factor of less than 7). These results constitute the first prediction of extensive quantum control in a collisional process.Comment: 9 pages, 1 figur

EU accession and income growth: an empirical approach

The dynamic effects from EU membership are crucial for the new member states to catch up with the average income level in the old member states. To gauge the dynamic effects, we follow a two-step procedure in which a gravity equation for bilateral trade shows the trade effect of EU membership and a growth regression yields the income effect of trade. Shared EU membership is found to increase trade between two of its member states with about 34%. EU membership may contribute to trade by inducing countries to improve the quality of their institutions. Trade increases by another 22% if institutions improve, yielding a total trade increase of 56%. Improved openness increases income by 37.5% according to our estimates. Adding a small direct effect of improved institutions on income, the total income effect of EU membership is 39% for the ten new members. This implies that EU membership, or its effect on trade and institutions, could lead to large economic gains for the new member states, but does not bring them economically on par with the old member states.

Understanding Anatomy Classification Through Attentive Response Maps

One of the main challenges for broad adoption of deep learning based models such as convolutional neural networks (CNN), is the lack of understanding of their decisions. In many applications, a simpler, less capable model that can be easily understood is favorable to a black-box model that has superior performance. In this paper, we present an approach for designing CNNs based on visualization of the internal activations of the model. We visualize the model's response through attentive response maps obtained using a fractional stride convolution technique and compare the results with known imaging landmarks from the medical literature. We show that sufficiently deep and capable models can be successfully trained to use the same medical landmarks a human expert would use. Our approach allows for communicating the model decision process well, but also offers insight towards detecting biases.Comment: Accepted at ISBI, 201

Ageing of the Population – A Social Policy Challenge

U prvom dijelu rada autor iznosi zapažanja o demografskim procesima i starenju stanovništva. U drugom dijelu prezentirani su osnovni podaci o starenju koje determinira produljenje ljudskog vijeka, s jedne, te smanjene stope demografske reprodukcije, s druge strane. U nastavku se iznose projekcije o starenju stanovništva u Hrvatskoj i Europi u narednim desetljećima. U trećem dijelu raspravlja se o javnim politikama usmjerenim na prevladavanje i ublažavanje posljedica starenja stanovništva. Riječ je o konceptu aktivnog starenja, reformama u mirovinskom i zdravstvenom sustavu te sustavu skrbi o starima. Na kraju, autor se osvrće na neke aspekte budućeg međugeneracijskog sporazuma koji se treba temeljiti na paradigmi usklađenoj s promjenama okolnosti u kojima ljudi danas žive.In the first part of the paper the author makes observations about the demographic processes and ageing of the population. In the second part some basic data about ageing that determines prolongation of life cycle are presented on one hand, and the decreased rates of demographic reproduction on the other. The second part of the paper outlines the projections about the ageing of the population in Croatia and Europe in the following decades. In the third part of the paper public policies focused on overcoming and mitigating consequences of the population ageing are discussed. These include the concept of active ageing, reforms in pension and health systems and the system of the care for the elderly. Finally, the author reflects on some aspects of the future intergenerational contract that should be based on the paradigm adjusted with the changes of circumstances in which people live nowadays
