International Portfolio Choice with Frictions: Evidence from Mutual Funds

Simon Tièche

Using data on international equity portfolio allocations by U.S. mutual funds, we estimate a portfolio expression derived from a standard mean-variance portfolio model extended with portfolio frictions. The optimal portfolio depends on the previous month a ...

Actor neural networks for the robust control of partially measured nonlinear systems showcased for image propagation through diffuse media

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Eirini Kakkava, Babak Rahmani, Ugur Tegin, Navid Borhani

The output of physical systems, such as the scrambled pattern formed by shining the spot of a laser pointer through fog, is often easily accessible by direct measurements. However, selection of the input of such a system to obtain a desired output is diffi ...

One-step access to N-enoxyimides by gold-catalysed addition of N-hydroxyimides to terminal alkynes

Nicolai Cramer, Coralie Danielle Annick Duchemin

N-Enoxyimides have become attractive substrates for novel catalytic transformations, yet their tedious multi-step synthesis hampers full exploitation of their synthetic potential. We report a gold(I)-catalyzed protocol to access N-enoxyimides from simple a ...

Rapid, Selective Extraction of Trace Amounts of Gold from Complex Water Mixtures with a Metal-Organic Framework (MOF)/Polymer Composite

Emad Oveisi, Wendy Lee Queen, Natalia Gasilova, Shuliang Yang, Daniel Teav Sun

With the ever-increasing production of electronics, there is an ensuing need for gold extraction from sources other than virgin mines. Currently, there are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts ...

Nanoparticle on mirror plasmonic nanostructure for molecular cavity optomechanics

Christophe Marcel Georges Galland, Santiago Tarrago Velez, Aqeel Ahmed

The plasmonic response of gold can be utilized to enhance the incident electromagnetic (EM) field by several orders of magnitude. When a gold nanoparticle is placed in close proximity to a gold film, the incident field can excite a deeply confined plasmon, ...

Gold-catalyzed domino cyclization-alkynylation reactions with EBX reagents: new insights into the reaction mechanism

Jérôme Waser, Paola Caramenti, Yifan Li

Gold-catalyzed domino processes constitute a useful alternative to C-H functionalization for the synthesis of functionalized (hetero)arenes. Herein, we report computational studies on the gold-catalyzed cyclization alkynylation of keto-allenes with ethynyl ...

Investment-based financing constraints and debt renegotiation

We consider how equity holders' bargaining power during financial distress influences the interactions between financing and investment decisions when the firm faces the upper limit of debt issuance. We obtain four results. First, weaker equity holders' ba ...

Capital supply uncertainty, cash holdings, and investment

Semyon Malamud, Erwan Morellec, Julien Hugonnier

We develop a dynamic model of investment, financing, and cash management decisions in which investment is lumpy and firms face capital supply uncertainty. We characterize optimal policies explicitly, demonstrate that smooth-pasting conditions may not guara ...

Enzyme and Acid Deconjugation of Plasma Sulfated Metanephrines

Sandrine Gerber

Background: Total (i.e. free + sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analyt ...

Essays in Information-Based Asset Pricing

Michael Nicolas Hasler

I started my Ph.D. studies in the Fall 2008, a period ex-post perceived as being at the core of the Financial Crisis. At that time my ideas were vague and I struggled to find a good research topic. As surprising as it might appear, in one single week the d ...

Intergranular penetration of liquid gold into stainless steel

Michel Rappaz, Léa Deillon, Jean-Daniel Wagnière, Denis Favez

Intergranular penetration of liquid 18 K gold into a superaustenitic stainless steel, which occurs during laser welding of these two materials, has been studied using a C-ring device which can be put under tensile stresses by a screw. It is shown that liqu ...
