Exponential Set-Point Stabilization of Underactuated Vehicles Moving in Three-Dimensional Space

This paper investigates the stabilization of underactuated vehicles moving in a three-dimensional vector space. The vehicle's model is established on the matrix Lie group SE(3), which describes the configuration of rigid bodies globally and uniquely. We focus on the kinematic model of the underactuated vehicle, which features an underactuation form that has no sway and heave velocity. To compensat

Systemic sustainability analysis in small and medium-sized enterprises (Smes)

Sustainability is rarely implemented in employee work practices in small and medium-sized enterprises (SMEs). The authors note that SMEs should implement sustainability practices as integrated part of work activities to ensure long term success. This paper describes an empirical study of SMEs sustainability on employee real work practices. A relevant perspective is offered by the triple bottom lin

Allergic contact dermatitis caused by dipropylene glycol diacrylate in the Omnipod® insulin pump

Background: Cases of allergic contact dermatitis (ACD) caused by isobornyl acrylate (IBOA) in the Omnipod® insulin pump have previously been reported. Objectives: To present three cases of patients with ACD caused by a new allergen in the pump, and results from chemical analyses. Methods: Omnipod pumps from different batches were analysed by gas chromatography–mass spectrometry. Aimed testing, wit

Natural history and surgical outcome of Rathke's cleft cysts—A study from the Swedish Pituitary Registry

Objective: Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow-up of Rathke's cleft cysts vary since data on the natural history are sparse. Patients and Design: Data at diagnosis and at

InN quantum dots on GaN nanowires grown by MOVPE

In this work, growth of InN quantum dots (QDs) on GaN nanowires (NWs) by metal-organic vapour phase epitaxy is demonstrated, illustrating the feasibility to combine 0D and 1D structures for nitride semiconductors. Selective area growth was used to generate arrays of c-oriented GaN NWs using Si3N4 as the mask material. In general, InN QDs tend to form at the NW edges between the m-plane side facets

STANDALONE SOFTWARE FOR DETECTING CHANGES IN SAR AND OPTICAL IMAGES

hange detection is an important application in remote sensing earth observation which leads to identification of significant environmental events, forest and agricultural landmonitoring. In this paper, we introduce a standalone softwarefor two well-known change detection methods, omnibus test and iteratively re-weighted multivariate alteration detection (IR-MAD). Omnibus test deals with synthetic

International cooperation for decarbonizing energy intensive industries: the case for a Green Materials Club

Basic materials are traded globally and responsible for roughly 22 % of global carbon emissions. It is technically possible for the energy intensive industries (EIIs) that produce these materials to reach zero emission, but at a cost. So far, the fear of carbon leakage has been a barrier for implementing ambitious domestic climate policies that targets theses globally traded commodities. The intro

Gas in Scattering Media Absorption Spectroscopy on Small and Large Scales: Towards the Extension of Lung Spectroscopic Monitoring to Adults

Numerous natural materials are porous, contain free gas, and are scattering light strongly. Scattering brings about a strong trapping of light and an associated prolonged transit time for photons through a medium. In contrast to the matrix materials, gas enclosures require very narrow‐band laser radiation for probing. We have in the present study used the gas in scattering media absorption spectro

Cancer follow-up supported by patient-reported outcomes in patients undergoing intended curative complex surgery for advanced cancer

Background and aim: Patient activation (PA) and Patient Involvement (PI) are considered elements in good survivorship. We aimed to evaluate the effect of a follow-up supported by electronic patient-reported outcomes (ePRO) on PA and PI. Method: From February 2017 to January 2019, we conducted an explorative interventional study. We included 187 patients followed after intended curative complex sur

Appendiceal tumours and pseudomyxoma peritonei : Literature review with PSOGI/EURACAN clinical practice guidelines for diagnosis and treatment

Pseudomyxoma Peritonei (PMP) is a rare peritoneal malignancy, most commonly originating from a perforated epithelial tumour of the appendix. Given its rarity, randomized controlled trials on treatment strategies are lacking, nor likely to be performed in the foreseeable future. However, many questions regarding the management of appendiceal tumours, especially when accompanied by PMP, remain unans

Overall risk and risk factors for metachronous peritoneal metastasis after colorectal cancer surgery : a nationwide cohort study

BACKGROUND: This study aimed to identify the cumulative incidence and risk factors of metachronous peritoneal metastasis (M-PM) from colorectal cancer in patients who had intended curative treatment. METHODS: Patients with colorectal cancer were identified using the Danish Colorectal Cancer Group database for 2006-2015. The Danish Pathology Registry and the Danish National Patient Registry were us

“You leave the chat with a different feeling than when you came in.”: A Content Analysis about Negative Experiences Following Instant Messaging Among Adolescents with and without a History of Non-Suicidal Self-Injury

Background: Instant messaging platforms seem to positively contribute to adolescent emotional well-being. However, some scholars show a link between the use of these platforms and negative emotional experiences.These emotions could be perceived as even more overwhelming for certain subgroups of adolescents, such as those who engage in non-suicidal self-injury (NSSI), and lead to self-injury to dea

Scaling properties of fractional momentum loss of high- pT hadrons in nucleus-nucleus collisions at sNN from 62.4 GeV to 2.76 TeV

Measurements of the fractional momentum loss (Sloss≡δpT/pT) of high-transverse-momentum-identified hadrons in heavy-ion collisions are presented. Using π0 in Au+Au and Cu+Cu collisions at sNN=62.4 and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons in Pb+Pb collisions measured by the ALICE experiment at the Large Hadron Collider, we studied

The formation and fate of planetesimals at planetary gap edges

High resolution observations with ALMA have revealed that concentric rings and gaps are common features in protoplanetary disks. The favored mechanism for creating these substructures are planet-disk interactions, in which growing planets open gaps in the disk, and particles become trapped at the pressure maxima that form at the corresponding gap edges. Since the particle density in these pressure

Older Voices: Supporting Community Radio Production for Civic Participation in Later Life

Community radio can support the process of having a voicein one’s community as a part of civic action, and promotecommunity dialogue. However, older adults are underrepresentedas producers of community radio shows in the UK,and face different challenges to their younger colleagues. Byworking within the radio production group of an existingorganisation of older adults, we identify the motivations a
