TFF (v.4.1): A Mathematica Notebook for the Calculation of One- and Two-Neutron Stripping and Pick-Up Nuclear Reactions

The program TFF calculates stripping single-particle form factors for one-neutron transfer in prior representation with appropriate perturbative treatment of recoil. Coupled equations are then integrated along a semiclassical trajectory to obtain one- and two-neutron transfer amplitudes and probabilities within first- and second-order perturbation theory. Total and differential cross-sections are then calculated by folding with a transmission function (obtained from a phenomenological imaginary absorption potential). The program description, user instructions and examples are discussed

Implementation of a disability management policy in a large healthcare employer: a quasi-experimental, mixed-method evaluation

Objective: This study describes the process and outcomes of the implementation of a strengthened disability management policy in a large Canadian healthcare employer. Key elements of the strengthened policy included an emphasis on early contact, the training of supervisors and the integration of union representatives in return-to-work (RTW) planning. Design: The study applied mixed methods, combining a process evaluation within the employer and a quasi-experimental outcome evaluation between employers for a 3-year period prior to and following policy implementation in January 2012. Participants: Staff in the implementation organisation (n=4000) and staff in a peer group of 29 large hospitals (n=1 19 000). Outcomes: Work disability episode incidence and duration. Results: Both qualitative and quantitative measures of the implementation process were predominantly positive. Over the 6-year observation period, there were 624 work disability episodes in the organisation and 8604 in the comparison group of 29 large hospitals. The annual per cent change in episode incidence in the organisation was −5.6 (95% CI −9.9 to −1.1) comparable to the annual per cent change in the comparison group: −6.2 (-7.2 to –5.3). Disability episode durations also declined in the organisation, from a mean of 19.4 days (16.5, 22.3) in the preintervention period to 10.9 days (8.7, 13.2) in the postintervention period. Reductions in disability durations were also observed in the comparison group: from a mean of 13.5 days (12.9, 14.1) in the 2009–2011 period to 10.5 days (9.9, 11.1) in the 2012–2014 period. Conclusion: The incidence of work disability episodes and the durations of work disability declined strongly in this hospital sector over the 6-year observation period. The implementation of the organisation’s RTW policy was associated with larger reductions in disability durations than observed in the comparison group

Importance of the single-particle continuum in BCS pairing with a pseudostate basis

In a recent work [arXiv:1510.03185] the use of the Transformed Harmonic Oscillator (THO) basis for the discretization of the singleparticle continuum into a Generalized Bardeen-Cooper-Schrieffer (BCS) formalism was proposed for the description of weakly bound nuclei. We make use of the flexibility of this formalism to study the evolution of the pairing when the nucleus becomes more and more weakly bound. Specifically we focus on the evolution of the occupation of the different partial waves in 22O when the Fermi level approaches zer

Continuum discretised BCS approach for weakly bound nuclei

The Bardeen-Cooper-Schrieffer (BCS) formalism is extended by including the single-particle continuum in order to analyse the evolution of pairing in an isotopic chain from stability up to the drip line. We propose a continuum discret ized generalized BCS based on single-particle pseudostates (PS). These PS are generated from the diagonalization of the single-particle Hamiltonian within a Transformed Harmonic Oscillator (THO) basis. The consistency of the results versus the size of the basis is studied. The method is applied to neutron rich Oxygen and Carbon is otopes and compared with similar previous works and available experimental data. We make use of the flexibility of the proposed model in order to study the evolution of the occupation of the low-energy continuum when the system becomes weakly bound. We find a larger influence of the non-resonant continuum as long as the Fermi level approaches zero.España, Ministerio de Economía y Competitividad FIS2014-53448-C2-1-PJunta de Andalucía FQM-160Junta de Andalucía P11-FQM-7632Programa Consolider-Ingenio CSD2007- 00042Comisión Europea 60037

Comparison of three different types of implantâ supported fixed dental prostheses: A longâ term retrospective study of clinical outcomes and costâ effectiveness

ObjectiveTo study the performance of 2â 3 posterior boneâ level dental implants constructed with either three nonâ splinted crowns (NSC), three splinted crowns (SC), or a 3â unit implantâ supported bridge over two implants (ISB).Material and methodsPatients treated with three metalâ ceramic NSC, SC, or an ISB were included in the present retrospective study. Implant survival and success rate as well as all biological and technical complications were collected. The cost associated with each of the treatment options was evaluated in the comparative analysis.ResultsOne hundred and fortyâ five patients (40 NSC, 52 SC, and 53 in the ISB) receiving 382 boneâ level implants (120 NSC, 106 ISB, and 156 SC) were included (mean followâ up of 76.2 months). Lack of success was observed in 33.8% of the total patient sample, being lower in the ISB group. Implant survival rates were 92.5% in the NSC, 100% in the ISB, and 88.5% in the SC, with significant difference noted between the ISB and SC (p = 0.01). Overall, 9.9% of the total implants were found to have periâ implantitis (PI), with 16.7% in the SC, 7.5% in the NSC, and 2.8% in the ISB. Patients presenting prosthodontic complications were significantly higher in NSC (32.5%) than ISB (13.2%) and SC (15.4%). The total cost of the ISB group was significantly lower when compared to the NSC and SC groups (p < 0.001).ConclusionsAn 3â unit implantâ supported bridge restoring 2 implants seems to present the most ideal longâ term therapeutic solution, among the investigated approaches in this study, in rehabilitating a 3â unit edentulous area.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/149366/1/clr13415.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/149366/2/clr13415_am.pd

Outcomes of root resection therapy up to 16.8Â years: A retrospective study in an academic setting

BackgroundRoot resection has been considered a viable treatment option for molars with furcation defects. However, need of a multidisciplinary approach could potentially deem this procedure less successful. The aim of the present article was to determine survival rates of root resection procedure and reasons for failure in an academic setting.MethodsPatient- related demographic data, medical history information, and relevant data pertaining to the root- resected teeth performed from January 1990 to September 2017 were reviewed through electronic and paper chart. Survival rates were analyzed using Kaplan- Meier estimate. Association between the reasons for failure and independent variables was established by a Pearson Chi- squared and Kruskal- Wallis test.ResultsA total of 85 patients with an average follow- up of 5 ± 4.3 years (range: 1 to 16.8 years) were included in the present article. A total of 47 molar teeth treated with root resection remained as part of the dentition (55.3%) and 38 (44.7%) failed. The mean survival time with the Kaplan- Mayer analysis was 109.9 months (9.1 years). Fracture (39.5%), caries (26.3%), and periodontal disease (23.7%) were the most common causes for failure. Interestingly, the majority of failures occurred in the first 4 years after therapy (n = 31; 81.5% of all failures).ConclusionsRoot resection therapy remains a treatment solution for molars with furcation defects. In an academic setting, >50% of teeth remained functional after 9 years of root resection therapy.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154884/1/jper10422.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154884/2/jper10422_am.pd

Using periodontal staging and grading system as a prognostic factor for future tooth loss: A long- term retrospective study

BackgroundA new classification of periodontal diseases aimed to identify periodontal disease based on a multidimensional staging and grading system has been recently proposed. However, up to date, its prognostic predictive capability has not been investigated. The aim of this study was to assess if parameters included in the new classification were predictive of tooth loss after a long- term follow- up (>10 years) in patients with periodontitis.MethodsPatients presented with periodontitis at the University of Michigan between January 1966 and January 2004 were screened and categorized according to the new classification of periodontitis. Number/Reasons of teeth loss in patients who underwent at least one session/year of maintenance during the entire follow- up period were extracted and used to analyze the prognostic capabilities of variables (staging, grading, and Extent) included in the new classification.ResultsA total number of 292 patients with a mean follow- up of 289.7 ± 79.6 months were included. 31 (10.6%) patients were classified as Stage 1, 85 (29.1%) as Stage 2, 146 (50%) as Stage 3, and 30 (10.3%) as Stage 4. For grading, 34 (11.7%) were classified as Grade A, 193 (66.1%) as Grade B, and 65 (22.2%) as Grade C. Results of multilevel Cox regression analyses revealed a statistically significant association between stage (HR:3.73 between Stage 4 and Stage 1) and grade (HR: 4.83 between Grade C and Grade A) at baseline and periodontal related tooth loss, whereas no differences were detected for the extent of periodontitis.ConclusionThis study provides the initial evidence regarding the predictive ability of the new classification of periodontitis. Patients in either Stage 4 or Grade C showed a significantly higher periodontal- related tooth loss.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154975/1/jper10442_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154975/2/jper10442.pd

Influence of keratinized mucosa on the surgical therapeutical outcomes of peri-implantitis

AimTo assess the impact of keratinized mucosa (KM) width around dental implants on surgical therapeutic outcomes when treating peri- implantitis.Material and MethodsSurgically treated peri- implantitis implants were divided into two groups (KM width  .01). Between T1 and T2, no major differences were noted on PPD reduction, BOP and MBL changes between the two groups. GEE modelling demonstrated that MBL severity prior to surgical therapy was a better predictor for implant survival than KM width.ConclusionSurgical outcome in treating peri- implantitis was influenced by the severity of bone loss present at the time of treatment and not by the presence of KM at the time of treatment.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154633/1/jcpe13250.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154633/2/jcpe13250_am.pd

Development of a nomogram for the prediction of periodontal tooth loss using the staging and grading system: A long- term cohort study

AimTo develop and internally validate a nomogram built on a multivariate prediction model including parameters from the new classification of periodontal diseases, able to predict, at baseline, the occurrence of tooth loss due to periodontal reason (TLP).Materials and MethodsA total of 315 individuals diagnosed with periodontal disease and receiving a minimum of one annual supportive periodontal therapy visit were included in the study. Patients were staged and graded based upon baseline data. The population was divided into a development (254 patients) and a validation (61 patients) cohort to allow subsequent temporal validation of the model. According to the TLP at the 10- year follow- up, patients were categorized as - low tooth loss- (- ¤ 1 TLP) or - high tooth loss- (- ¥ 2 TLP). Bootstrap internal validation was performed on the whole data set to calculate an optimism- corrected estimate of performance.ResultsThe generated nomogram showed a strong predictive capability (AUC = 0.81) and good calibration with an intercept = 0 and slope = 1. These findings were confirmed by internal validation using bootstrapping (average bootstrap AUC = 0.83).ConclusionsThe clinical implementation of the present nomogram guides the prediction of patients with high risk of disease progression and subsequent tooth loss for personalized care.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/163380/2/jcpe13362.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/163380/1/jcpe13362_am.pd
