THE SPEED OF LIMIT ORDER EXECUTION IN THE SPANISH STOCK EXCHANGE [PDF]

open access: yes
The objective of this work is to study empirically the factors influencing the execution time in the Spanish Stock Exchange. Our dataset includes the orders and transactions of the assets belonging to IBEX 35 in the period between July and September 2000.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A F.E. UPPER BOUND LIMIT ANALYSIS MODEL FOR MASONRY CURVED AND 3D STRUCTURES, WITH AND WITHOUT FRPREINFORCEMENT

open access: yes, 2010
The aim of this thesis is to propose a new efficient numerical tool, based on the kinematic theorem of limit analysis, for the study of masonry shell and 3D structures with or without FRP reinforcement. The approach consists of two steps.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Arbitrage-free Limit Order Books and the Pricing of Order Flow Risk [PDF]

open access: yes
This paper builds on the landmark contribution of Glosten (1994) by treating the determination of limit order supply schedules as an exercise in asset pricing theory with the possible sizes of incoming market orders as the value-relevant states of nature,

Integrated structural analysis tool using linear matching method part 2 : Application and verification

open access: yes, 2014
In an accompanying paper, a new integrated structural analysis tool using the LMM framework for the assessment of design limits in plasticity including load carrying capacity, shakedown limit, ratchet limit and steady state cyclic response of structures ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Hidden Limit Orders and Liquidity in Order Driven Markets [PDF]

open access: yes
This paper analyzes the rationale for the submission of hidden limit orders, and compares opaque and transparent limit order books. In my sequential model, the limit order trader may be informed with some probability.

Integrated structural analysis tool using linear matching method part 1 : Software development

open access: yes, 2014
A number of direct methods based upon the Linear Matching Method (LMM) framework have been developed to address structural integrity issues for components subjected to cyclic thermal and mechanical load conditions.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
