The Principle of Respect for Human Vulnerability and Assisted Reproductive Technologies

2016

The chapter tackles the assisted reproductive technologies (ARTs), and the incorporation of two controversial procedures to increase the number of individuals who may satisfy their wish to have children: international commercial surrogacy and mitochondrial transfer. Both of them have an important point in common: the high degree of involvement within the reproduction process demanded to a different woman from the woman who will be the legal mother. In international surrogacy, a woman undergoes a baby gestation for another woman in a different country, who will be the legal mother since the baby is born. In mitochondrial transfer, a woman donates her eggs so that her mitochondria may be used…

Latest Frontier Technology and Design of the ATLAS Calorimeter Trigger Board Dedicated to Jet Identification for the LHC Run 3

2016

To cope with the enhanced luminosity of the beam delivered by the Large Hadron Collider (LHC) in 2020, the “A Toroidal LHC ApparatuS” (ATLAS) experiment has planned a major upgrade. As part of this, the trigger at Level1 based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature Extractors, which each use different physics objects for the trigger selection. The article focusses on the jet Feature EXtractor (jFEX) prototype, one of the three types of Feature Extractors. Up to 2 TB/s have to be processed to provide jet identification (including large area jets) and measurements of global variables within few hundred nanoseconds latency budget.…

Design and testing of the high speed signal densely populated ATLAS calorimeter trigger board dedicate to jet identification

2017

Abstract—The ATLAS experiment has planned a major upgrade in view of the enhanced luminosity of the beam delivered by the Large Hadron Collider (LHC) in 2021. As part of this, the trigger at Level-1 based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature Extractors (three in total), which each uses different physics objects for the trigger selection. The contribution focusses on the jet Feature EXtractor (jFEX) prototype. Up to a data volume of 2 TB/s has to be processed to provide jet identification (including large area jets) and measurements of global variables within few hundred nanoseconds latency budget. Such requirements translate …

Development of an optical link card for the upgrade phase II of TileCal experiment

2010

This work presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment as part of the evaluation of different technologies for the final choice in the next two years. The board is designed as a mezzanine which can work independently or plugged in the Optical Multiplexer Board of the TileCal backend electronics. It includes two SNAP 12 optical connectors able to transmit and receive up to 75 Gbps and one SFP optical connector for lower speeds and compatibility with existing hardware as the Read Out Driver. All processing is done in a Stratix II GX FPGA. Details are given on the hardware design including signal and …

The Loss of Structural Integrity in Damaged Spruce Needles from Locations Exposed to Air Pollution I. Mesophyll and Central Cylinder

1990

In connection with the new type of forest damage, the individual disease situation of two-year-old spruce (Picea abies) needles was analyzed histopathologically in forest areas exposed to different levels of O3-, SO2- and NO3- pollution. Early damage results from losses of chlorophyll in the mesophyll cells. The bleaching is more intensive towards the apex in severely damaged needles. The cytoplasm is aggregated at the cell wall and the chloroplasts show definite structural damage as well. The mesophyll cells below the epidermis, or the cells adjacent to the vascular bundle sheath, appear to be particularly susceptible. Collapsed cells (bone cells), which increase in number with damage, can…

Adding Path-Functional Dependencies to the Guarded Two-Variable Fragment with Counting

2017

The satisfiability and finite satisfiability problems for the two-variable guarded fragment of first-order logic with counting quantifiers, a database, and path-functional dependencies are both ExpTime-complete.

Refitting of an eco-friendly sailing yacht: numerical prediction and experimental validation

2016

A 4.60 m sailing yacht, made with a flax fiber composite and wood, has been refitted with the aim of hull weight reduction and performance improvement during regattas. The first objective was obtained with a lightening of internal hull reinforcements while the second one with a reduction of the maximum beam, in order to minimize the longitudinal moment of inertia. The refitting was first simulated via CAD-FEM interaction to establish the feasibility of the procedure and to verify the structural integrity. The resulting hull was then instrumented with strain gauges and tested under typical rigging and sailing conditions. Results obtained by the numerical modeling and measured from experiment…

H-KPP : Hypervisor-Assisted Kernel Patch Protection

2022

We present H-KPP, hypervisor-based protection for kernel code and data structures. H-KPP prevents the execution of unauthorized code in kernel mode. In addition, H-KPP protects certain object fields from malicious modifications. H-KPP can protect modern kernels equipped with BPF facilities and loadable kernel modules. H-KPP does not require modifying or recompiling the kernel. Unlike many other systems, H-KPP is based on a thin hypervisor and includes a novel SLAT switching mechanism, which allows H-KPP to achieve very low (≈6%) performance overhead compared to baseline Linux.

Internal audit professional principles and academic literature over the last decade: is there a gap to bridge

2022

The Institute of Internal Auditors (IIA) has defined the ethical principles internal auditors must adhere to, allowing them to create a common understanding of ethical behaviour within their profession, thereby promoting ethical culture. This paper aims to analyse the role of these principles in the main branches of internal audit research over the last decade. We examine the most important articles published in this field and categorise them into seven main strands. We assess the extent to which these strands focus on the IIA ethical principles, aiming to identify research gaps in the extant literature. Our findings show that the literature dealing with ethical principles in the recruitmen…
