The International Linear Collider Project—Its Physics and Status

2021

The discovery of Higgs particle has ushered in a new era of particle physics. Even though the list of members of the standard theory of particle physics is now complete, the shortcomings of the theory became ever more acute. It is generally considered that the best solution to the problems is an electron–positron collider that can study Higgs particle with high precision and high sensitivity; namely, a Higgs factory. Among a few candidates for Higgs factory, the International Linear Collider (ILC) is currently the most advanced in its program. In this article, we review the physics and the project status of the ILC including its energy expandability.

Secure integration of multiprotocol instant messenger

2017

Pidgin communicator is a multiprotocol instant messenger client, developed by open source community. It was originally a third party client of AIM (AOL Instant Messenger) protocol for Linux operating system founded in 1998. At present, its main goal is to provide common interface for every protocol it supports, so the user does not need care about protocol to use or peer's IM identifier, while he just want to talk with a Bob. The work focuses mainly on security and functionality aspects like password storage strategies, integration with plugins which provide privacy of communication. This paper shares experiences has been gained during the process of developing and replacement of existing c…

Bagging, bumping, multiview, and active learning for record linkage with empirical results on patient identity data

2011

Record linkage or deduplication deals with the detection and deletion of duplicates in and across files. For this task, this paper introduces and evaluates two new machine-learning methods (bumping and multiview) together with bagging, a tree-based ensemble-approach. Whereas bumping represents a tree-based approach as well, multiview is based on the combination of different methods and the semi-supervised learning principle. After providing a theoretical background of the methods, initial empirical results on patient identity data are given. In the empirical evaluation, we calibrate the methods on three different kinds of training data. The results show that the smallest training data set, …

Physical Activity and Exercise in the Maintenance of the Adult Skeleton and the Prevention of Osteoporotic Fractures

2013

Abstract Physical activity and exercise are promoted as a nonpharmacological strategy to maintain or enhance musculoskeletal health in adults and prevent osteoporotic fracture. Less clear is the optimal mode, intensity, duration, and frequency of activity to achieve this objective. Although a substantial osteogenic response to appropriate mechanical loading is clearly evident in animal models and strongly supported from athlete cross-sectional and prospective studies, the results from exercise interventions in adults are less impressive with modest net benefits generally of 1% to 3% in bone mineral density (BMD) (g/cm2) at the clinically relevant hip and spine following prolonged weight-bea…

Impact of the process of isolating humic acids from peat on their propertiesA paper submitted to the Journal of Environmental Engineering and Science.

2009

Humic substances (HS) can be isolated in preparative quantities from low rank coal, peat, and soil. Traditionally, treatment with solutions of NaOH, KOH, or metal salts (K4P2O7) has been used for their isolation. The aim of this article is to study the effectiveness of different technologies in extracting HS from peat as well as the impact of the different extractive technologies on the properties of the isolated HS. Yields of HS depend very much on the extraction process (extractant, temperature, pretreatment procedures, solvent, mixing intensity); however, the properties of the substances obtained (molecular mass, number of functional groups, spectral characteristics) differ significantly…

Designing Guarantee Options in Defined Contribution Pension Plans

2015

The shift from defined benefit (DB) to defined contribution (DC) is pervasive among pension funds, due to demographic changes and macroeconomic pressures. In DB all risks are borne by the provider, while in plain vanilla DC all risks are borne by the beneficiary. For DC to provide income security some kind of guarantee is required. A minimum guarantee clause can be modeled as a put option written on some underlying reference portfolio of assets and we develop a discrete model that optimally selects the reference portfolio to minimise the cost of a guarantee. While the relation DB-DC is typically viewed as a binary one, the model can be used to price a wide range of guarantees creating a con…

On the Effects of Relative Performance Feedback in a Risk Elicitation Task: Evidence From a Lab Experiment

2018

This paper experimentally investigates the influence of different non-payoff-relevant feedback regimes on motivation, competitiveness and risk-taking behaviors in a risk elicitation task. We explore four feedback regimes: private feedback, full ranking feedback, top-5 ranking feedback, and non-ranking feedback based on the median performance of peers. We found that providing relative performance feedback increases risk-taking behavior, especially when using a top-5 ranking. Feedback regimes that provide a user with rank-based feedback have adverse effects on the users' attitudes as they increase competitiveness while failing to increase intrinsic motivation and performance motivation. In co…

Design of Implanted RFID Tags for Passive Sensing of Human Body: The STENTag

2012

Numerical processing of passive UHF-RFID tags' response may provide physical insight about the hosting object or about the nearby environment. This idea is here extended to implanted antennas with the purpose to sense the evolution of some human physiological and pathological process involving a local change of effective permittivity inside the body. The goal is to understand how master the design of this class of devices taking into account both communication and sensing capabilities. An ad hoc design methodology is here presented and discussed by means of a realistic medical case concerning the modification of an endo-vascular device to achieve a STENTag able to sense the state of the ves…
