Causal impacts of epidemics and pandemics on food supply chains : a systematic review

Cardoso, Brenda ; Cunha, Luiza ; Leiras, Adriana ; Gonçalves, Paulo ; Yoshizaki, Hugo ; de Brito Junior, Irineu ; Pedroso, Frederico

In: Sustainability, 2021, vol. 13, no. 17, p. 28

The epidemics and pandemics can severely affect food supply chains, including producers, retailers, wholesalers, and customers. To minimize their impacts, it is fundamental to implement effective policies that ensure continuity in the provision, affordability, and distribution of basic food items. This research identifies the main impacts of pandemics and epidemics on food supply chains and ...

The Impact of Response Measures on COVID-19-Related Hospitalization and Death Rates in Germany and Switzerland

Huber, Martin ; Feuerriegel, Stefan

In: Swiss Journal of Economics and Statistics, 2020, vol. 156, no. 10, p. 1-19

We assess the impact of the timing of lockdown measures implemented in Germany and Switzerland on cumulative COVID-19-related hospitalization and death rates. Our analysis exploits the fact that the epidemic was more advanced in some regions than in others when certain lockdown measures came into force, based on measuring health outcomes relative to the region-specific start of the epidemic...

Striatal responsiveness to reward under threat‐of‐shock and working memory load : A preliminary study

Gaillard, Claudie ; Guillod, Matthias ; Ernst, Monique ; Torrisi, Salvatore ; Federspiel, Andrea ; Schoebi, Dominik ; Recabarren, Romina E. ; Ouyang, Xinyi ; Mueller-Pfeiffer, Christoph ; Horsch, Antje ; Homan, Philipp ; Wiest, Roland ; Hasler, Gregor ; Martin-Soelch, Chantal

In: Brain and Behavior, 2019, no. 9, p. 1-21

Introduction: Reward and stress are important determinants of motivated behaviors. Striatal regions play a crucial role in both motivation and hedonic processes. So far, little is known on how cognitive effort interacts with stress to modulate reward processes. This study examines how cognitive effort (load) interacts with an unpredictable acute stressor (threat-of-shock) to modulate motivational...

Dissecting human antibody responses: useful, basic and surprising findings

Lanzavecchia, Antonio

In: EMBO molecular medicine, 2018, vol. 10, p. e8879

Human memory B cells and plasma cells represent a rich source of antibodies that have been selected in response to human pathogens. In the last decade, different methods have been developed to interrogate the human memory repertoire and isolate monoclonal antibodies. I will discuss how a target‐agnostic approach based on high‐throughput screening of antibodies produced by cultured B cells...

Truncating the memory time in nonequilibrium dynamical mean field theory calculations

Schüler, Michael ; Eckstein, Martin ; Werner, Philipp

In: Physical Review B, 2018, vol. 97, no. 24, p. 245129

The nonequilibrium Green's functions (NEGF) approach is a versatile theoretical tool, which allows to describe the electronic structure, spectroscopy, and dynamics of strongly correlated systems. The applicability of this method is, however, limited by its considerable computational cost. Due to the treatment of the full two-time dependence of the NEGF, the underlying equations of motion...
