Impacts of Fed’s decisions on emerging countries : an empirical analysis & investment solution

Amigo Weidemann, Simon ; Sterchi, Kurt (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2019 ; TDIBM 64.

On July 13th, 2019, the Fed decided to reduce its interest rates by 25 basis points. Its first since October 2008. A decision that could be thought of as a good thing for the emerging countries’ economies. Indeed, according to economic theories and history, they would benefit from a significant breath of fresh air. Legend has it that the Fed's will have a significant impact on emerging...

Rapid evolution of invasive traits facilitates the invasion of common ragweed, Ambrosia artemisiifolia

Sun, Yan ; Roderick, George K.

In: Journal of Ecology, 2019, vol. 107, no. 6, p. 2673–2687

Invasive alien plants, together with organisms introduced for biological control, are ideal study systems with which to address questions of whether, and how fast, organisms adapt to changing environments. We compared populations of common ragweed, Ambrosia artemisiifolia, from native (USA) and introduced (China) ranges at similar latitudes, together with herbivores introduced for biological...

Coupling of electronic and nuclear motion in a negative ion resonance: Experimental and theoretical study of benzene

Allan, Michael ; Čurík, Roman ; Čársky, Petr

In: The Journal of Chemical Physics, 2019, vol. 151, no. 6, p. 064119

We present calculated and measured elastic and vibrational excitation cross sections in benzene with the objective to assess the reliability of the theoretical method and to shed more light on how the electronic motion of the incoming electron is coupled with the nuclear motion of the vibrations. The calculation employed the discrete momentum representation method which involves solving the...

Measurement of ultra-trace level of intact oxytocin in plasma using SALLE combined with nano-LC–MS

Liu, Dan ; Han, Xiaoli ; Liu, Xinxin ; Cheng, Mengchun ; He, Meixi ; Rainer, Gregor ; Gao, Huiyuan ; Zhang, Xiaozhe

In: Journal of Pharmaceutical and Biomedical Analysis, 2019, vol. 173, p. 62–67

Measurement of peptides such as oxytocin in plasma is a critical challenge in clinical research because of their extreme low concentrations as well as the tremendous interferencing substances co-presented in plasma. In this study, we developed an efficient salt-out assisted liquid-liquid extraction (SALLE) to treat plasma, and then analyzed the samples using nano-LC–MS to quantify intact...

Scalable content-based publish/suscribe and application to online trading

Barazzutti, Raphaël P. ; Felber, Pascal (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Publish/subscribe is a popular messaging pattern that provides efficient and decoupled information dissemination in distributed environments. Publishers generate a flow of information as publications, which are routed to subscribers based on their interests expressed as subscriptions. Matching events against filters has a non-negligible processing cost. Our first contribution within this...

VAPYRIN Marks an endosomal trafficking compartment involved in arbuscular mycorrhizal symbiosis

Bapaume, Laure ; Laukamm, Sabine ; Darbon, Geoffrey ; Monney, Corinne ; Meyenhofer, Felix ; Feddermann, Nadja ; Chen, Min ; Reinhardt, Didier

In: Frontiers in Plant Science, 2019, vol. 10, p. -

Arbuscular mycorrhiza (AM) is a symbiosis between plants and AM fungi that requires the intracellular accommodation of the fungal partner in the host. For reciprocal nutrient exchange, AM fungi form intracellular arbuscules that are surrounded by the peri-arbuscular membrane. This membrane, together with the fungal plasma membrane, and the space in between, constitute the symbiotic interface,...
