Spatio-temporal clustering and forecasting method for free-floating bike sharing systems

Free-floating bike sharing systems are an emerging new generation of bike rentals, that eliminates the need for specific stations and allows to leave a bicycle (almost) everywhere in the network. Although free-floating bikes allow much greater spontaneity and flexibility for the user, they need additional operational challenges especially in facing the bike relocation process. Then, we suggest a m

Quantifying the impacts of horizontal and vertical equity in transit route planning

Equity refers to a fair sharing of costs or resources. Horizontal equity concerns distribution among individuals or groups with the same necessities, whereas vertical equity should be considered in situations with different levels of needs. This paper deals with transit service, looking at how to make it equitable from a spatial and social point of view. Traditionally equity has been neglected in

Planning and Design of Equitable Free-Floating Bike-Sharing Systems Implementing a Road Pricing Strategy

Promoting a more sustainable development of urban realities is one of the most important goals of the recent decades. One possible strategy to undertake in order to achieve this objective is the implementation of a road pricing: tolling private cars when passing by certain roads of the network could be a way to tone down the traffic congestion and, at the same time, encourage the shifting towards

A road network design model considering horizontal and vertical equity : Evidences from an empirical study

Most of the models for solving the transportation Network Design Problem (NDP) often neglect equity goals that, assuming the societal function of transportation systems, should play an important role. The NDP should be addressed to solutions in which the outcomes of the design (costs and/or benefits) are distributed as fairly as possible among the potential users or class of users. In this paper,

Measurement of the Higgs boson mass in the H → ZZ⁎ → 4ℓ and H → γγ channels with s=13 TeV pp collisions using the ATLAS detector

The mass of the Higgs boson is measured in the H→ZZ⁎→4ℓ and in the H→γγ decay channels with 36.1 fb−1 of proton–proton collision data from the Large Hadron Collider at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector in 2015 and 2016. The measured value in the H→ZZ⁎→4ℓ channel is mH ZZ⁎=124.79±0.37GeV, while the measured value in the H→γγ channel is mH γγ=124.93±0.40GeV. Combining

"... vare sig de levande eller de döda" : om Gud och människa i Ruts bok

I denna artikel ger jag en förklaring till den för Ruts bok karakteristiska transparensen i guds gärningar. Att JHVH framställs som verksam genom huvudkaraktärerna Rut och Boas goda gärningar har sin grund i bokens etisk-didaktiska syfte. Berättelsen gudomliggör dessa modellfigurers handlingar genom att framställa dem som Guds egna. att JHVH identifierar sig med ett sådant liv i solidaritet visar

The Organisation of Welfare Services on Quasi-Markets - a Study of Elderly Care in Sweden

This paper examines how a Scandinavian country organises elderly care as a welfare service on a quasi-market. More specifically, it deals with how public officers work with meeting citizens’ need and demand, while at the same time struggle with political decrees, changes in the political climate, as well as the whims of the market. Swedish elderly care is used as an example of how a welfare servic

Reduced wound healing capacity in alcohol abusers - reversibility after withdrawal

BackgroundAlcohol abusers have increased risk of wound complications following surgical procedures, however the development of complications is reduced after preoperative withdrawal from alcohol. Therefore the aim of the study was to evaluate wound healing at alcohol abuse and after withdrawal. MethodsIn total 16 alcohol abusers were included and tested. Nine abusers were able to abstain from alco

Motivation of trauma patients to stop smoking after admission to the emergency department

Every smoker should be offered smoking cessation treatment when they present for clinical care. The Readiness to Change-Smokers (RTC-S) questionnaire and the Heidelberg Smoking History (HSH) are brief questionnaires that divide patients into three stages. The purpose of this study was to prospectively compare the performance of each questionnaire at identifying patients who will successfully quit

Risk reduction: perioperative smoking intervention

Smoking is a well-known risk factor for perioperative complications. Smokers experience an increased incidence of respiratory complications during anaesthesia and an increased risk of postoperative cardiopulmonary complications, infections and impaired wound healing. Smokers have a greater risk of postoperative intensive care admission. Even passive smoking is associated with increased risk at ope

ESI and MALDI LC/MS-MS approaches for large scale protein, identification and quantification : Are they equivalent?

An approach for large scale protein identification and quantification was described. The peptide mixtures from the strong cation exchange (SCX) fractionated protein digests were separated and analyzed by HPLC MS/MS. The human fibrobalst nuclei were purified from stimulated and non-stimulated cells. The quantification results with MALDI and ESI LC/MS were shown to be identical within experimental e

Preservation potential of keratin in deep time

Multiple fossil discoveries and taphonomic experiments have established the durability of keratin. The utility and specificity of antibodies to identify keratin peptides has also been established, both in extant feathers under varying treatment conditions, and in feathers from extinct organisms. Here, we show localization of feather-keratin antibodies to control and heat-treated feathers, testifyi

Effect of smoking cessation intervention on results of acute fracture surgery: a randomized controlled trial

Tobacco smoking is a major health and economic concern and is also known to have a significant negative effect on surgical outcomes. The benefits of a smoking cessation intervention prior to elective orthopaedic surgery have been evaluated previously. Our aim was to assess whether a smoking cessation program, initiated during the acute hospitalization period and carried out for six weeks, could re

Risk reduction before surgery. The role of the primary care provider in preoperative smoking and alcohol cessation

Daily smokers and hazardous drinkers are high-risk patients, developing 2-4 times more complications after surgery. Preoperative smoking and alcohol cessation for four to eight weeks prior to surgery halves this complication rate. The patients' preoperative contact with the surgical departments might be too brief for the hospital to initiate these programmes. Therefore, it was relevant to evaluate

Effects of Intravenous Fluid Restriction on Postoperative Complications: Comparison of Two Perioperative Fluid Regimens: A Randomized Assessor-Blinded Multicenter Trial

Objective: To investigate the effect of a restricted intravenous fluid regimen versus a standard regimen on complications after colorectal resection.Summary Background Data: Current fluid administration in major surgery causes a weight increase of 3–6 kg. Complications after colorectal surgery are reported in up to 68% of patients. Associations between postoperative weight gain and poor survival a
