ObjectiveTreatment of massive irreparable rotator cuff tears (RCT) has shown limited clinical success and a variety of subsequent complications. Superior capsule reconstruction (SCR) has been proved to reestablish superior stability but does not restore the dynamic force or shoulder kinematics. There are numerous reports of the short‐term failure of SCR grafts at the glenoid side, which relate to the non‐biological healing of grafts. To restore both dynamic and static stability and to provide biologic augmentation, an integrated procedure for massive irreparable RCT using an Achilles tendon–bone allograft (ATBA) was developed.MethodThis was a retrospect study completed between October 2019 and April 2020. A 71‐year‐old woman with massive and irreparable rotator cuff tears was enrolled in our study. The ATBA was folded into a double‐layer structure. The superior layer (proximal portion) served as a bridge patch to dynamic the glenohumeral joint, while the inferior layer (distal portion) served as the superior capsule to restore static stability of glenohumeral joint. To enhance biologic healing on the glenoid side, we fixed the calcaneus of the graft on the superior–posterior side of the superior glenoid rim. The recovery of shoulder function (including strength, range of motion, acromiohumeral interval, and fatty infiltration) was assessed at 6 months postoperation.ResultAt 6‐month follow‐up, the patient's strength had improved significantly (from abduction of grade 3 preoperatively to grade 4 at 6 months). Radiographic analysis showed an increase in the acromiohumeral interval from 3 to 7 mm. Magnetic resonance imaging revealed an intact graft, with the thickness of the ligament part maintained (at 6–7 mm). Most importantly, recovery of atrophy and fatty infiltration of the supraspinatus were observed. No graft tears were observed on the glenoid side.ConclusionThis technique could provide a preferable treatment option by restoring shoulder kinematics and augmentating biological healing for patients with massive irreparable RCT.
Reducing the Generosity and Increasing the Conditionality of Welfare Benefits for People with Disability: “Turning the Supertanker” or “Squeezing the Balloon”?*
Authors: Broadway Barbara , McVicar Duncan 
Published: August 2020

AbstractWe compare outcomes of disability benefit applicants before and after a major Australian reform of disability benefits, with two groups of applicants who fulfilled the same medical impairment criteria accepted or rejected based only on application date. The reform reduced the generosity and increased the conditionality of welfare payments by shifting partially disabled claimants from disability benefits to unemployment benefits. This led to increases in the probability not only of switching out of unemployment benefits on to alternative benefits, but also of exiting welfare altogether. However, because those who exited had a higher probability of subsequently returning to welfare, the reform had no impact on the proportion receiving welfare 12 or 24 months later.
Jobs Multipliers: Evidence from a Large Fiscal Stimulus in Spain*
Authors: Alloza Mario , Sanz Carlos 
Published: August 2020

AbstractWe estimate the unemployment effects of a large fiscal stimulus in Spain (Plan Español para el Estímulo de la Economía y el Empleo, the Spanish Plan for the Stimulus of the Economy and Employment, commonly known as Plan E), in which the national government transferred funds to municipalities to carry out local investment projects. Using a difference‐in‐difference approach by exploiting variation in the timing of the execution of projects across municipalities, we find that 100,000 euros of stimulus reduced unemployment by 0.74 job‐years. We allow for possible spatial effects (i.e., the propagation of the stimulus to neighboring municipalities), and we find that these are sizable, representing 13.8 percent of the “local” effect. Our estimate of the multiplier falls in the lower range of previous work.

AbstractObjectiveTo describe the clinical presentation of a dog with fatal hemorrhage from an aortoesophageal fistula (AEF) immediately following endoscopic removal of an osseous esophageal foreign body.Case SummaryA 12‐year‐old, male mixed‐breed dog presented to a university hospital with a 6‐day history of gagging, hematemesis, and anorexia. Physical examination upon arrival was unremarkable. Blood work revealed leukocytosis without anemia. Thoracic radiographs from the referring veterinarian demonstrated the presence of an osseous esophageal foreign body at the level of the heart base. Subsequently, esophagoscopy was performed under general anesthesia. A triangular‐shaped, osseous esophageal foreign body was visualized at the level of the heart base and successfully removed. Following its removal, a deep, nonbleeding, presumably nonperforated, esophageal ulcer was revealed. While recovering from anesthesia, the dog's condition acutely deteriorated, with absence of spontaneous respiration, severe tachycardia, hypotension, white‐pale mucous membranes, and hypothermia. Severe anemia was present, with hypovolemic shock likely secondary to acute, postprocedural bleeding. Medical management included rapid packed red blood cell transfusion, crystalloid fluid therapy, and tranexamic acid. Despite initial stabilization, several hours later, the dog suffered cardiac arrest and cardiopulmonary resuscitation (CPR) was unsuccessful. At postmortem examination, a 1‐mm AEF was identified on the ventral aspect of the aorta that communicated with the overlying esophagus.New or Unique Information ProvidedAortoesophageal fistulas should be considered in any patient with severe bleeding following esophagoscopy. A history of hematemesis in a dog with an esophageal foreign body should raise suspicion of an AEF and dictate case management accordingly.

Elasto-Plastic Impact on Auxetic/Metal Foams
Authors: Kumar N. , Khaderi S. N. , Tirumala Rao K. 
Published: August 2020

AbstractWe investigate the normal impact of a rigid sphere on a half-space of elasto-plastic auxetic/metal foam using the finite element method. The dependence of the coefficient of restitution, peak force, maximum displacement, and contact duration on the yield strain, impact velocity, and elastic and plastic Poisson’s ratio is analyzed. For a given elastic Poisson’s ratio, the coefficient of restitution generally decreases with an increase in the plastic Poisson’s ratio and impact velocity. When the plastic Poisson’s is maintained constant, the coefficient of restitution increases with an increase of the elastic Poisson’s ratio. These trends are explained using plastic energy dissipation. The energy dissipation trends are further investigated by decomposing it into deviatoric and hydrostatic parts. For a given impact velocity, the peak force is relatively insensitive to most of the elastic and plastic Poisson’s ratio combinations. We also show that for the cases where the elastic and plastic Poisson’s ratios are equal, the coefficient of restitution is relatively insensitive to their actual values. These findings can guide researchers to identify the right elastic and plastic Poisson’s ratio combinations so that lattice materials with exceptional energy absorbing capacity can be designed using topology optimization.
Wireless Cyber-Physical System Performance Evaluation Through a Graph Database Approach
Authors: Kashef Mohamed , Liu Yongkang , Montgomery Karl , Candell Richard 
Published: August 2020

Abstract
Despite the huge efforts to deploy wireless communications technologies in smart manufacturing scenarios, some manufacturing sectors are still slow to massive adoption. This slowness of widespread adoption of wireless technologies in cyber-physical systems (CPSs) is partly due to not fully understanding the detailed impact of wireless deployment on the physical processes especially in the cases that require low latency and high reliability communications. In this article, we introduce an approach to integrate wireless network traffic data and physical processes data to evaluate the impact of wireless communications on the performance of a manufacturing factory work cell. The proposed approach is introduced through the discussion of an engineering use case. A testbed that emulates a robotic manufacturing factory work cell is constructed using two collaborative-grade robot arms, machine emulators, and wireless communication devices. All network traffic data are collected and physical process data, including the robots and machines states and various supervisory control commands, is also collected and synchronized with the network data. The data are then integrated where redundant data are removed and correlated activities are connected in a graph database. A data model is proposed, developed, and elaborated; the database is then populated with events from the testbed, and the resulting graph is presented. Query commands are then presented as a means to examine and analyze network performance and relationships within the components of the network. Moreover, we detail the way by which this approach is used to study the impact of wireless communications on the physical processes and illustrate the impact of various wireless network parameters on the performance of the emulated manufacturing work cell. This approach can be deployed as a building block for various descriptive and predictive wireless analysis tools for CPS.
Application of the Bilateral Filter for the Reconstruction of Spiral Bevel Gear Tooth Surfaces From Point Clouds
Authors: Gonzalez-Perez Ignacio , Guirao-Saura Pedro L. , Fuentes-Aznar Alfonso 
Published: August 2020

Abstract
Reconstruction of gear tooth surfaces from point clouds obtained by noncontact metrology machines constitutes a promising step forward not only for a fast gear inspection but also for reverse engineering and virtual testing and analysis of gear drives. In this article, a new methodology to reconstruct spiral bevel gear tooth surfaces from point clouds obtained by noncontact metrology machines is proposed. The need of application of a filtering process to the point clouds before the process of reconstruction of the gear tooth surfaces has been revealed. Hence, the bilateral filter commonly used for 3D object recognition has been applied and integrated in the proposed methodology. The shape of the contact patterns and the level of the unloaded functions of transmission errors are considered as the criteria to select the appropriate settings of the bilateral filter. The results of the tooth contact analysis of the reconstructed gear tooth surfaces show a good agreement with the design ones. However, stress analyses performed with reconstructed gear tooth surfaces reveal that the maximum level of contact pressures is overestimated. A numerical example based on a spiral bevel gear drive is presented.

Abstract
Discarded cigarette butts contain polymers, biomass, and a variety of toxins that cause an adverse effect to the human health and environment for years. The cigarette residuals are not recyclable and often get mixed with other kinds of wastes so that much of this waste ends up in landfills. This study investigates the safe disposal of cigarette butts by the thermochemical pathways using pyrolysis and gasification. Mass loss during its thermal decomposition was examined first using a thermogravimetric analyzer. The effect of temperature on the pyrolysis and CO2-assisted gasification was then conducted using a semi-batch reactor with a focus on the flowrate of total syngas and its gas components. Syngas yield, energy recovery, as well as energy efficiency were calculated and compared. The effect of temperature on the CO2 consumption during the gasification process was also examined. The thermal decomposition of cellulose acetate, tar, and wrapping paper were the main contributors during the pyrolysis of cigarette butt. However, the gasification process mainly consisted of the pyrolysis, cracking, and reforming reactions in the gas phase and gasification of char derived from wrapping paper. An increase in temperature enhanced the syngas flowrate, syngas yield, and gas efficiency while decreasing the char yield and reaction time for both the processes. Energy recovery from gasification was higher than pyrolysis due to added CO generation. The maximum syngas energy of 13.0 kJ/g under the gasification condition at 1223 K was 67.2% higher as compared with the pyrolysis. High temperature strongly affected the gasification reaction, while it was negligible at a temperature lower than 1023 K. Complete conversion occurred during gasification at 1223 K that provided only ash residue. The CO2 gasification of cigarette butts provided an effective pathway to utilize 0.5 g CO2/g feedstock at 1223 K to form valuable CO by the Boudouard reaction. Compared with the gasification of other solid wastes, syngas energy yield from cigarette butts was found to be higher than syngas from polystyrene and polyethylene terephthalate. These results support the effectiveness of thermochemical pathways in the rapid conversion of cigarette butts to valuable syngas along with CO2 utilization.
Rotational Low-Impedance Physical Human–Robot Interaction Using Underactuated Redundancy
Authors: Audet Julien M. , Gosselin Clément 
Published: August 2020

Abstract
This paper extends the concept of underactuated redundancy for physical human–robot interaction (pHRI) in a context of industrial assembly by introducing a novel 1-dof gravity balanced rotational manipulator. The proposed architecture consists of a rotational active counterweight with a passive joint equipped with an encoder. The proposed architecture is first described, and the static equilibrium conditions are used to describe the operation of the mechanism. Then, alternative architectures are briefly introduced. Finally, an experimental validation is provided to demonstrate the viability of the concept for rotational low impedance pHRI.
The Application of the Integral Momentum Balance on the Pressure Drop of a Sudden Contraction
Authors: Malcherek Andreas , Müller Sebastian 
Published: August 2020

Abstract
A new approach based on the momentum balance to calculate the pressure drop in turbulent flow through sharp-edged axisymmetric sudden contractions is presented. The momentum balance needs the velocity as well as the pressure distributions on the boundaries of the control volume. These distributions are obtained by a series of numerical simulations with different settings for the discharge, as well as the contraction ratio. The numerical model itself is validated by the comparison of the simulated and measured pressure drops in a laboratory experiment at different positions. To get easily applicable hydraulic formulations for the pressure drop depending on the discharge and the contraction ratio, the missing momentum and pressure coefficients are determined from the simulated velocity and pressure distributions. Only the pressure coefficient shows a dependency on the contraction ratio. After fitting the dependency by a simple analytical expression, a new formulation for the hydraulics of a sharp-edged sudden contraction based solely on momentum balance was obtained. The comparison with own experimental results as well as the classical parameterization of Idelchik show in both cases very good agreement.
Prescribing Physical Activity in Parks and Nature: Health Care Provider Insights on Park Prescription Programs
Authors: Besenyi Gina M. , Hayashi Emi B. , Christiana Richard W. 
Published: August 2020

Background: Health care providers (HCPs) promoting physical activity (PA) through programs such as Park Prescriptions (ParkRx) are gaining momentum. However, it is difficult to realize provider PA practices and program interest, and differences in program success exist by provider type (eg, primary vs secondary). This study explored HCPs’ (1) PA counseling practices, (2) knowledge/interest in ParkRx, (3) barriers and resources needed to implement PA counseling and ParkRx programs, and (4) differences in primary versus secondary HCPs. Methods: An e-survey administered in Spring/Summer 2018 to HCPs in 3 states examined study objectives. Results: Respondents (n = 278) were mostly primary (58.3%) HCPs. The majority asked about patient PA habits and offered PA counseling (mean = 5.0, SD = 1.5; mean = 4.8, SD = 1.5), but few provided written prescriptions (mean = 2.5, SD = 1.6). Providers were satisfied with their PA counseling knowledge (mean = 3.8, SD = 1.0) but not with prescribing practices (mean = 3.2, SD = 1.1). Secondary HCPs placed higher importance (P = .012) and provided significantly more written PA prescriptions (P = .005). Time was a common barrier to prescribing PA (mean = 3.4, SD = 1.2), though more so for primary HCPs (P = .000). Although few HCPs knew about ParkRx programs, 81.6% expressed interest. Access to park information and community partnerships was an important resource for program implementation. Conclusions: HCPs underutilize PA prescriptions. Despite little awareness, HCPs were interested in ParkRx programs.

Abstract
Recovering the time-evolving relationship between arc magmatism and deformation, and the influence of anisotropies (inherited foliations, crustal-scale features, and thermal gradients), is critical for interpreting the location, timing, and geometry of transpressional structures in continental arcs. We investigated these themes of magma-deformation interactions and preexisting anisotropies within a middle- and lower-crustal section of Cretaceous arc crust coinciding with a Paleozoic boundary in central Fiordland, New Zealand. We present new structural mapping and results of Zr-in-titanite thermometry and U-Pb zircon and titanite geochronology from an Early Cretaceous batholith and its host rock. The data reveal how the expression of transpression in the middle and lower crust of a continental magmatic arc evolved during emplacement and crystallization of the ∼2300 km2 lower-crustal Western Fiordland Orthogneiss (WFO) batholith. Two structures within Fiordland’s architecture of transpressional shear zones are identified. The gently dipping Misty shear zone records syn-magmatic oblique-sinistral thrust motion between ca. 123 and ca. 118 Ma, along the lower-crustal WFO Misty Pluton margin. The subhorizontal South Adams Burn thrust records mid-crustal arc-normal shortening between ca. 114 and ca. 111 Ma. Both structures are localized within and reactivate a recently described &gt;10 km-wide Paleozoic crustal boundary, and show that deformation migrated upwards between ca. 118 and ca. 114 Ma. WFO emplacement and crystallization (mainly 118–115 Ma) coincided with elevated (&gt;750 °C) middle- and lower-crustal Zr-in-titanite temperatures and the onset of mid-crustal cooling at 5.9 ± 2.0 °C Ma−1 between ca. 118 and ca. 95 Ma. We suggest that reduced strength contrasts across lower-crustal pluton margins during crystallization caused deformation to migrate upwards into thermally weakened rocks of the mid-crust. The migration was accompanied by partitioning of deformation into domains of arc-normal shortening in Paleozoic metasedimentary rocks and domains that combined shortening and strike-slip deformation in crustal-scale subvertical, transpressional shear zones previously documented in Fiordland. U-Pb titanite dates indicate Carboniferous–Cretaceous (re)crystallization, consistent with reactivation of the inherited boundary. Our results show that spatio-temporal patterns of transpression are influenced by magma emplacement and crystallization and by the thermal structure of a reactivated boundary.

ObjectiveTo predict antibiotic use after initial treatment with ibuprofen using data from a randomised controlled trial comparing ibuprofen to pivmecillinam in the treatment of women with symptoms of an uncomplicated urinary tract infection (UTI).Setting16 sites in a primary care setting in Norway, Sweden and Denmark.ParticipantsData from 181 non-pregnant women aged 18–60 presenting with symptoms of uncomplicated UTI, initially treated with ibuprofen.MethodsUsing the least absolute shrinkage and selection operator logistic regression model, we conducted analyses to see if baseline information could help us predict which women could be treated with ibuprofen without risking treatment failure and which women should be recommended antibiotics.ResultsOf the 143 women included in the final analysis, 77 (53.8%) recovered without antibiotics and 66 (46.2 %) were subsequently prescribed antibiotics. In the unadjusted binary logistic regression, the number of days with symptoms before inclusion (<3 days) and feeling moderately unwell or worse (≥4 on a scale of 0–6) were significant predictors for subsequent antibiotic use. In the adjusted model, no predictors were significantly associated with subsequent antibiotic use. The area under the curve of the final model was 0.66 (95% CI: 0.57 to 0.74).ConclusionWe did not find any baseline information that significantly predicted the use of antibiotic treatment. Identifying women who need antibiotic treatment to manage their uncomplicated UTI is still challenging. Larger data sets are needed to develop models that are more accurate.Trial registration numberClinicalTrials.gov (NCT01849926).
