Pseudotumor after Total Wrist Arthroplasty Mimicking a Neoplasm
Authors: Ghijsen Sophie C. , Nap Frank J. , Schuurman Arnold H. 
Published: December 2021

Abstract
Background Total wrist arthroplasty can lead to a variation of complications. One of these is the formation of a pseudotumor. Although this complication is well known after total hip arthroplasty, it is rare in patients with wrist implants.
Case Description A 55-year-old man with a Universal 2 (Integra, Plainsboro, NJ) wrist prosthesis was seen with a progressive mass on the radial side of his wrist since 1 year, initially suspicious for a neoplasm. However, after exploration, histopathology confirmed a particle-induced foreign body reaction.
Literature Review There is little literature on pseudotumor formation after total wrist arthroplasty. Currently, there is no clear consensus about the etiology of pseudotumors but possible causes may include foreign body reaction, hypersensitivity, and wear debris.
Clinical Relevance This case report shows that particle debris-induced pseudotumors should be considered when a patient with a wrist prosthesis presents with a mass suspicious for a neoplasm. In addition, treatment options of pseudotumors after wrist arthroplasty in literature is discussed.

Published: December 2021

Abstract
General CuCo2O4 electrodes suffer a very low reversible capacity and poor cycling stability because of easily fading phenomena and volume change during cycling. To optimize the electrode, a facile method is conducted to fabricate a novel electrode of Cu@CuCo2O4@polypyrrole nanoflowers. Due to larger specific surface area and more electrochemical reactive areas of CuCo2O4@polypyrrole nanoflowers, the pseudocapacitance of the in situ grown CuCo2O4@polypyrrole (912 F g−1 at 2 A g−1) is much higher than the pristine CuCo2O4 (618 F g−1 at 2 A g−1). Remarkably, the CuCo2O4@polypyrrole (cathode) and active carbon (anode) are used to assemble an asymmetric supercapacitor, which exhibits a relatively high energy density of 90 Wh kg−1 at a power density of 2519 W kg−1 and 35 Wh kg−1 at a high-power density of 9109 W kg−1, and excellent cycling stability (about 90.4% capacitance retention over 10 000 cycles). The prominent performance of CuCo2O4@polypyrrole makes it as a potential electrode for supercapacitor.

Abstract
Developing efficient and stable multifunctional electrocatalyst is very important for zinc–air batteries in practical. Herein, semiconductive spinel CuFe2O4 supported Co–N co-doped carbon (Co-NC) and CoFe alloy nanoparticles were proposed. In this strategy, the three-dimensional ordered macroporous CuFe2O4 support provides rich channels for mass transmission, revealling good corrosion-resistance and durability at the same time. ZIF-67 derived Co-NC decoration improves the conductivity of the catalyst. Further, the uniformly distributed Co-NC and CoFe nanoparticles (C/CF) dramatically promote the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) performance. Accordingly, C/CF@CuFe2O4 catalyst shows remarkable bifunctional electrocatalytic activity, with an ORR half-wave potential of 0.86 V, and an OER over-potential of 0.46 V at 10 mA cm−2. The zinc–air battery using this catalyst exhibits a power density of 95.5 mW cm−2 and a durable cyclability for over 170 h at a current density of 10 mA cm−2, which implies a great potential in practical application.

Published: December 2021

Abstract
Acoustofluidicly manipulated microbubbles (MBs) and echogenic liposomes (ELIPs) have been suggested as drug delivery systems for the ‘on demand’ release of drug in target tissue. This requires a clear understanding of their behaviour during ultrasonication and after ultrasonication stops. The main focus of this study is to investigate the behaviour of MBs and ELIPs clusters after ultrasonication stops and the underlaying cause of cluster diffusion considering electrostatic repulsion, steric repulsion and Brownian motion. It also examines the capability of existing models used to predict MBs’ attraction velocity due to secondary radiation force, on predicting ELIPs’ attraction velocity. Tunable resistive pulse sensing (TRPS) and phase analysis light scattering (PALS) techniques were used to measure zeta potentials of the agents and the size distributions were measured using TRPS. The zeta potentials were found to be −2.43 mV and −0.62 mV for Definity™ MBs, and −3.62 mV and −2.35 mV for ELIPs using TRPS and PALS, respectively. Both agents were shown to have significant cluster formation at pressures as low as 6 kPa. Clusters of both agents were shown to diffuse as sonication stops at a rate that approximately equals the sum of the diffusion coefficients of the agents forming them. The de-clustering behaviours are due to Brownian motion as no sign of electrostatic repulsion was observed and particles movements were observed to be faster for smaller diameters. These findings are important to design and optimise effective drug delivery systems using acoustofluidically manipulated MBs and ELIPs.
Renormalization group analysis of near-field induced dephasing of optical spin waves in an atomic medium
Authors: Grava S , He Y , Wu S , Chang D E 
Published: December 2021

Abstract
While typical theories of atom–light interactions treat the atomic medium as being smooth, it is well-known that microscopic optical effects driven by atomic granularity, dipole–dipole interactions, and multiple scattering can lead to important effects. Recently, for example, it was experimentally observed that these ingredients can lead to a fundamental, density-dependent dephasing of optical spin waves in a disordered atomic medium. Here, we go beyond the short-time and dilute limits considered previously, to develop a comprehensive theory of dephasing dynamics for arbitrary times and atomic densities. In particular, we develop a novel, non-perturbative theory based on strong disorder renormalization group (RG), in order to quantitatively predict the dominant role that near-field optical interactions between nearby neighbors has in driving the dephasing process. This theory also enables one to capture the key features of the many-atom dephasing dynamics in terms of an effective single-atom model. These results should shed light on the limits imposed by near-field interactions on quantum optical phenomena in dense atomic media, and illustrate the promise of strong disorder RG as a method of dealing with complex microscopic optical phenomena in such systems.

Published: December 2021

Abstract
We present the first theoretical and experimental evidence of time-resolved dynamic x-ray magnetic linear dichroism (XMLD) measurements of GHz magnetic precessions driven by ferromagnetic resonance in both metallic and insulating thin films. Our findings show a dynamic XMLD in both ferromagnetic Ni80Fe20 and ferrimagnetic Ni0.65Zn0.35Al0.8Fe1.2O4 for different measurement geometries and linear polarizations. A detailed analysis of the observed signals reveals the importance of separating different harmonic components in the dynamic signal in order to identify the XMLD response without the influence of competing contributions. In particular, RF magnetic resonance elicits a large dynamic XMLD response at the fundamental frequency under experimental geometries with oblique x-ray polarization. The geometric range and experimental sensitivity can be improved by isolating the 2ω Fourier component of the dynamic response. These results illustrate the potential of dynamic XMLD and represent a milestone accomplishment toward the study of GHz spin dynamics in systems beyond ferromagnetic order.
Combined detection of supernova neutrino signals
Authors: Sheshukov A. , Vishneva A. , Habig A. 
Published: December 2021

Abstract
Supernova neutrino detection in neutrino and dark matter
experiments is usually implemented as a real-time trigger system
based on counting neutrino interactions within a moving time
window. The sensitivity reach of such experiments can be improved by
taking into account the time profile of the expected signal. We
propose a shape analysis of the incoming experimental data based on
a log likelihood ratio variable containing the assumed signal
shape. This approach also allows a combination of potential
supernova signals in different detectors for a further sensitivity
boost. The method is tested on the NOvA detectors to study their
combined sensitivity to the core-collapse supernova signal, and also
on KamLAND, Borexino and SK-Gd as potential detectors of
presupernova neutrinos. Using the shape analysis enhances the signal
significance for supernova detection and prediction, as well as the
sensitivity reach of the experiment. It also extends the supernova
prediction time when applied to the presupernova neutrino signal
detection. Enhancements achieved with the shape analysis persist
even in the case when the actual signal doesn't match the expected
signal model.
ShapeFit: extracting the power spectrum shape information in galaxy surveys beyond BAO and RSD
Authors: Brieden Samuel , Gil-Marín Héctor , Verde Licia 
Published: December 2021

Abstract
In the standard (classic) approach, galaxy clustering measurements from spectroscopic surveys are compressed into baryon acoustic oscillations and redshift space distortions measurements, which in turn can be compared to cosmological models. Recent works have shown that avoiding this intermediate step and fitting directly the full power spectrum signal (full modelling) leads to much tighter constraints on cosmological parameters. Here we show where this extra information is coming from and extend the classic approach with one additional effective parameter, such that it captures, effectively, the same amount of information as the full modelling approach, but in a model-independent way. We validate this new method (ShapeFit) on mock catalogs, and compare its performance to the full modelling approach finding both to deliver equivalent results. The ShapeFit extension of the classic approach promotes the standard analyses at the level of full modelling ones in terms of information content, with the advantages of i) being more model independent; ii) offering an understanding of the origin of the extra cosmological information; iii) allowing a robust control on the impact of observational systematics.

Published: December 2021

Abstract
The demand for LPG (Liquefied Petroleum Gas) detection constitutes a major and critical problem in the field of gas detection. LPG is used for domestic appliances used in the heating of buildings, producing petrochemicals and as a motor fuel. The current paper used the fabricated ZnO, in addition to TGS 813, TGS 2600, TGS 4160, TGS 3870, TGS 822 as semiconductor gas sensors, in varying temperature and load resistance in a prototype setup so as to explore each model’s accuracy for performance prediction for gas detection. The fabricated ZnO gas sensor is used also to detect the LPG. The comparison is done between gas sensors array and the fabricated one from ZnO. The actual results are put in comparison with the empirical algorithms’ predictions. The optimal model is found to be the full quadratic empirical model based on the lowest error with different sensors.

Published: December 2021

Abstract
This article uses computational models to evaluate the potential of copper-indium-gallium-diselenide (CIGS) thin film solar cells. The use of cadmium sulphide (CdS) renders the solar cell environmentally hazardous. A zinc sulphide (ZnS) that is non-toxic and has a large bandgap is studied as a potential replacement for cadmium sulphide in CIGS-based solar cells. The present research focuses on the impact of the CIGS-based solar cell bandgap absorber layer by increasing the absorber layer thickness (0.1-2 μm) using the solar cell simulator simulation tool SCAPS. The basic simulation produces 18.2 % efficiency with a CdS buffer layer, which is 9.95% better than the previously published work. The Simulated efficiency is 22.16% for the CIGS solar cell using ZnS. The simulation of solar cell characteristics of how the thickness of the absorber layer, the gallium grading (efficiency ranges up to 22.25 %) is demonstrated, showing the effect of buffer layer (ZnS) on the current of short-circuit density (JSC), open-circuit voltage (Voc), fill factor (FF), and efficiency (η) of the solar cell.

Published: December 2021

Abstract
Continuous urban development and sustainable development goals to develop cities and transform them into smart cities faces many challenges that appear in the transfer of electricity to this place or the difficulty and high price of building a station in this place. And power loss and voltage instability are major problems in distribution systems. However, these problems are typically mitigated by efficient network reconfiguration. Distributed generation (DG) can be used in the distribution systems to fight the increase of the load demand and it improve power generation systems and improvement the system efficiency. But it is very strange that if the generators are placed in an ill-considered size and in an inappropriate location, this causes the system to weaken, which has a bad effect on use, and this is not desirable. Not only that, but with the increase in the demand for power to cope with the increasing loads, stages of loss of power appear when it enters the distribution stage through transmission lines to loads. Therefore, the process of selecting the appropriate size and location with the general cost and taking into account environmental factors is a very important process to ensure the stability and reliability of the system .In the event that the generators are placed in an inappropriate size and in an inappropriate location, this leads to many problems in voltage, power and distribution, which causes severe weakness of the system, which causes an increase in the chance that electricity is not connected to the loads. So the appropriate way to choose the right placement and size is very important. In this study, we study the best place in which distribution generators can be added and the best size for them using PSO and its implementation on IEEE14 standard systems

Published: December 2021

Abstract
Radiation degradation of semi-insulating GaAs detectors by 8 MeV electrons up to doses of 1500 kGy is studied in this paper. The influence of irradiation on GaAs material parameters and on spectrometric and electrical properties of fabricated detectors is evaluated. The detector material was degraded before contact preparation, which ensured separation of radiation degradation solely to the bulk material, excluding the contact degradation. The positron annihilation lifetime spectroscopy (PALS) was involved to characterize the substrate material together with galvanometric measurements. Radiation-induced mono-vacancies were clearly identified by PALS in the irradiated materials with increasing concentration up to 2.8 × 1016 cm−3 at maximal applied dose. In correlation with defect concentration the electron Hall mobility decreased with dose down to 3270 cm2 V−1 s−1 and resistivity increased up to 5.22 × 108 Ω cm at 1500 kGy. The bulk material properties influenced the parameters of fabricated detectors. The detectors lost their current blocking behaviour at 1000 kGy according to current-voltage measurements. The charge collection efficiency during alpha-particle and gamma ray measurements almost exponentially decreased with applied dose from initial 40% down to 5% at 1500 kGy in the case of alpha spectrometry and from 48% to 12% at 500 kGy for gamma spectrometry.
Talking about trees: the territorial classification of native forests in the Argentinian Chaco
Authors: Ceddia M G , Frey S , Inguaggiato C , Tschopp M 
Published: December 2021

Abstract
Deforestation represents an important contributor to climate change. For this reason, identifying conditions that enable the adoption of policies halting or reversing this process is crucial to avoid catastrophic climate change. The Argentinian Gran Chaco is a hotspot of deforestation, mainly due to the expansion of capital-intensive agriculture. In Argentina, the introduction of the national forest law (NFL) represents an important step to protect the remaining forests. However, in the Chaco ecoregion, the implementation of the NFL by the different provinces is extremely heterogeneous. Previous research has provided rich descriptions of the dynamics behind the implementation of the NFL. Yet this research, mainly based on qualitative approaches, does not allow for a systematic analysis of the conditions leading to more or less stringent implementations of the NFL. To address this gap, we first combine the socio-ecological systems framework with historical materialism to generate a plausible hypothesis for the heterogeneous implementation of the NFL across the 12 different provinces of the Argentinian Chaco. Specifically, we hypothesise that it is the differences in contextual factors (i.e. differences in forest cover), material/economic conditions (i.e. presence and extent of capital-intensive agriculture) and the strength of pro- and anti-deforestation coalitions, which lead to a heterogeneous territorial classification of native forests across the various provinces. Subsequently, we test the hypothesis by developing thorough case studies via qualitative comparative analysis. This approach allows us to study in a more systematic way the reasons for the observed institutional heterogeneity. The results show that the proportion of native forests characterised as of low conservation value reflects both the environmental context (i.e. the extent of native forests) as well as the material/economic conditions (i.e. the extent of capital-intensive agriculture) and the presence of strong pro-deforestation cultures, expressed via pro-deforestation coalitions.
Implementation of a strategy for identification and monitoring of clinical outcome measures in a department of pharmacy
Authors: Vest Mary-Haston , Stout Stephanie , Waldron Kayla 
Published: December 2021

Abstract

Purpose
To describe a department of pharmacy strategy to identify and monitor outcome measures that represent the impact of clinical pharmacy services on patient outcomes.

Summary
Our department established the Clinical Impact Committee, with the goal of developing and maintaining an approach to demonstrate the impact of clinical pharmacists on patient care outcomes. We describe the committee’s structure, aims, and key stakeholders, inclusive of both departmental leadership and clinical pharmacist representatives across service lines. We also describe the systematic process used by the committee for identifying clinical outcome measures that are both aligned with organizational priorities and representative of pharmacists’ impact. This involved assembly of a crosswalk of clinical outcome measures that are prioritized by the organization and attributable to the work of clinical pharmacists. We found it imperative to connect pharmacists’ efforts to the priorities of the organization to demonstrate value and continue to justify pharmacy resources. Once the crosswalk of clinical outcome measures was assembled, the Clinical Impact Committee leveraged modified Delphi methodology to build consensus on the measures to prioritize. Once determined, the final outcome measures were developed into outcomes dashboards, to be monitored by the committee and leveraged by frontline pharmacists.

Conclusion
Our organization was successful in developing a structure, the Clinical Impact Committee, to identify, prioritize, and monitor measures that demonstrate pharmacist contributions to patient care outcomes. Further, our approach includes an intentional alignment with organizational priorities, allowing us to understand and communicate the contributions of our teams to meeting-defined organizational quality priorities.

Abstract

Background
Surgery is the most effective treatment in patients with painful chronic pancreatitis and a dilated pancreatic duct. Studies reporting the outcomes of selected surgical approach according to the pancreatic head size in these patients are lacking.

Method
This was a retrospective, observational single-centre study of consecutive patients who underwent either a Frey procedure or extended lateral pancreaticojejunostomy (eLPJ) for pain due to chronic pancreatitis with a dilated main pancreatic duct (5 mm or more) between 2006 and 2017. A Frey procedure was used in patients with pancreatic head enlargement (40 mm or more) and eLPJ (full-length pancreaticojejunostomy, including transection of the gastroduodenal artery) in others. A biliodigestive bypass was added in the case of biliary obstruction.

Results
Overall, 140 of 220 patients met the eligibility criteria: 70 underwent a Frey procedure and 70 an eLPJ. Hepaticojejunostomy was added in 17.1 per cent of patients (Frey: 24.3 per cent; eLPJ: 10.0 per cent (P = 0.025)). Major morbidity occurred in 15.0 per cent of patients (Frey: 21.4 per cent; eLPJ: 8.6 per cent (P = 0.033)). After a median 7.8 years of follow-up, the mean (s.d.) decrease in Izbicki pain score was 33 (27) points (34 (28) points after a Frey procedure; 32 (26) points after an eLPJ). Pain relief was reported as ‘very much’ by 87.5 per cent of patients (Frey: 86.1 per cent; eLPJ: 88.9 per cent) and as ‘partial’ by 11.1 per cent (Frey: 13.8 per cent; eLPJ: 8.3 per cent).

Conclusion
Selective-use of either a Frey procedure or eLPJ in patients with symptomatic chronic pancreatitis was-associated with low morbidity and long-term pain relief. Adding a-biliodigestive bypass did not increase morbidity.
