Technical note: Revised projections onto convex sets reconstruction of multi‐shot diffusion‐weighted imaging
Authors: Hu Zhangxuan , Zhang Zhe , Ma Xiaodong , Jing Jing , Guo Hua 
Published: December 2022

AbstractBackgroundHigh‐resolution diffusion‐weighted imaging (DWI) is usually achieved through multi‐shot acquisitions and parallel imaging‐based reconstructions. Multiple POCS (projections onto convex sets) based algorithms have been proposed for DWI reconstructions. However, the slow convergence of POCS and the suboptimal quality of the reconstructed images limit their applications.PurposeIn this study, a revised POCS algorithm for multi‐shot DWI reconstruction is proposed based on FISTA (fast iterative shrinkage‐thresholding algorithm) to achieve faster convergence and higher accuracy.MethodsIn FISTA, the next iteration is computed based on two previous iterations, instead of only the previous one, to improve the convergence speed. This scheme is adopted into the relevant POCS‐based algorithms, including POCSENSE (POCS‐based sensitivity‐encoding), POCSMUSE (POCS‐based multiplexed sensitivity‐encoding), iPOCSMUSE (iterative POCSMUSE), and POCS‐ICE (POCS‐enhanced inherent correction of motion‐induced phase errors) to address the slow convergence problem. Simulations and in vivo experiments were performed to evaluate the performance of the proposed method.ResultsExperimental results show that the proposed method enables faster convergence compared to the original POCS. For example, for a spiral DWI simulation using eight‐shot interleaves and having SNR of 20 dB, the iteration number needed for the revised POCS‐ICE decreases by about 70% to achieve approximately the same nRMSE level as POCS‐ICE. Additionally, it improves image quality in terms of fewer artifacts compared with the original POCS.ConclusionsThe revised DWI reconstruction methods can achieve higher convergence rates than the original POCS‐based algorithms and higher image quality with the same iteration numbers. As such, the proposed method can serve as a practical and efficient reconstruction method for multi‐shot DWI.

AbstractFlexible and electrically conductive polymer nanocomposite materials are gaining popularity as EMI shield materials. Herein, we report the successful fabrication of Thermoplastic polyurethane (TPU)/polybutylene adipate‐co‐terephthalate (PBAT)/dodecyl amine modified multi‐walled carbon nanotubes (MWCNT)‐based biodegradable polymer nanocomposite films employing solvent mixing and casting technique. The FESEM analysis of the cryofractured TPU/PBAT blend (containing 50 wt% of both the polymers) is found to be perfectly co‐continuous. Field emission scanning electron microscopy (FESEM), High‐resolution transmission electron microscopy (HRTEM) analysis followed by a selective dissolution test of polymer nanocomposites revealed that MAm nanofillers are mostly confined to the PBAT phase. The electrical percolation threshold is found to be between 3 and 5 wt% of dodecyl amine modified MWCNT loading as the electrical conductivity and EMI shielding efficiency are found to be shifting from 10−4 to 0.827 S/cm and −29.4 and −36 dB respectively as the nanofiller loading is increased from 3 to 5 wt% keeping the thickness of the polymer nanocomposite films constant at 0.8 mm.
Electrodeless discharge in water: Reactive species in liquid and gas phase and energy cost for nitrogen fixation
Authors: Luo JingYi , Nie LanLan , Liu DaWei , Lu Xinpei 
Published: December 2022

AbstractOne of the main barriers stopping plasma activated water (PAW) in many practical applications is its high energy cost. On the other hand, a careful review of published literature finds that all the studies reported on the PAW only focus on the reactive species generated in liquid, and there is no measurement of the possible reactive species in the gas phase during the generation of PAW, which might contain high concentration reactive species especially for the cases when gas bubbling is used during the generation of PAW. In this paper, an electrodeless plasma device is reported, where distilled water, tap water, and saline water are used as working liquid while O2, N2, and air are flowing through the liquid. Not only the reactive species presented in the liquid phase, the reactive species contained in the gas phase were analyzed for the first time in the field of PAW nitrogen fixation. It was found that the total number of moles of reactive species in gas phase is actually several times higher than that in liquid phase. Only when considering the reactive nitrogen species (RNS) in the liquid phase, the lowest energy cost is about 18.97 MJ/mol when air is flowing though the tap water. On the other hand, when both the RNS in liquid phase and in gas phase are included, the lowest energy cost achieved is 5.53 MJ/mol when air is flowing through distilled water, which is only one‐seventh of the lowest energy cost reported on PAW. This study helps us shed light on plasma nitrogen fixation by using PAW, which has been greatly underestimated due to the overlooking of gas phase products of PAW in the past.
Two faces of decomposability in organizational search: Evidence from singles versus albums in the music industry 1995–2015
Authors: Chang Sungyong 
Published: December 2022

AbstractResearch SummaryThis study proposes that decomposability may generate a trade‐off in search. This study compares a decomposed search (i.e., producing and evaluating a decomposed module) and an integrated search (i.e., producing and evaluating a full‐scale product). While the former can allow firms to experiment with more alternatives than can the latter, it may be more vulnerable to imperfect evaluation because a larger number of promising alternatives could be omitted after the initial evaluation. The reason for this is that not only do more alternatives face an unlucky draw in their initial evaluation but also a decomposed search may lead firms to set a higher performance target for giving a second‐chance opportunity. I test this theory and mechanisms by comparing singles (i.e., decomposed modules) and albums (i.e., full‐scale products) in the music industry.Managerial SummaryThis study highlights a hidden cost of experimentation‐oriented practices: an increased chance of terminating investment in promising business options (e.g., resources, technologies, and new business projects) after initial small‐scale experimentation. A growing number of technological innovations (e.g., software development kits, cloud computing, and e‐commerce platforms) have enabled firms to experiment with new business options by producing modules rather than full‐scale products. These innovations benefit management practices for experimentation, such as lean start‐up or design thinking, and have thus gained popularity among practitioners. This study suggests that while producing and evaluating a module enables firms to experiment with more options, it may increase the chance of terminating investment in promising business options because firms may set a higher performance target for subsequent investment after initial small‐scale experimentation.

Published: December 2022

AbstractThe repair of bone defects caused by osteosarcoma resection remains a clinical challenge because of the tumor recurrence and bacterial infection. Combining tumor and bacterial therapy with bone regeneration properties in bone implants is a promising strategy for the treatment of osteosarcoma. Here, a layer of MgO/FeOx nanosheet is constructed on the Ti implant to prevent tumor recurrence and bacterial infection, while simultaneously accelerating bone formation. This MgO/FeOx double metal oxide demonstrates good peroxidase activity to catalyze H2O2, which is rich in tumor microenvironment, to form reactive oxygen species (ROS), and shows good photothermal conversion capacity to produce photothermal effect, thus synergistically killing tumor cells and eliminating tumor tissue. In addition, it generates a local alkaline surface microenvironment to inhibit the energy metabolism of bacteria to enhance the photothermal antibacterial effect. Furthermore, benefiting from the generation of a Mg ion‐containing alkaline microenvironment, this MgO/FeOx film can promote the osteogenic differentiation of osteoblast and angiogenesis of vascular endothelial cells in vitro as well as accelerated bone formation in vivo. This study proposes a multifunctional platform for integrating tumor and bacterial therapy and bone regeneration, which has good application prospects for the treatment of osteosarcoma.

Published: December 2022

ZusammenfassungDas gesellschaftliche Bewusstsein für Gefährdungen und Krisen ist angesichts großer sozialer Herausforderungen im beginnenden 21. Jahrhundert zunehmend geschärft. Trotz aller Bemühungen Gefährdungen vorzubeugen, wird deutlich, dass Prävention und Vorsorge Krisen und ihre Folgen nicht ausschließen oder umfänglich abwenden können. Neben Begriffen wie Risiko und Krise hat vor allem der Resilienzbegriff in diesem Zusammenhang im wissenschaftlichen wie öffentlichen Diskurs enorm an Bedeutung gewonnen. In dem Beitrag werden verschiedene konzeptionelle Zugänge und Anwendungen des Resilienzbegriffs vorgestellt und mögliche Strategien zur Stärkung von Resilienz diskutiert.
Back-to-back inclusive dijets in DIS at small x: Sudakov suppression and gluon saturation at NLO
Authors: Caucal Paul , Salazar Farid , Schenke Björn , Venugopalan Raju 
Published: December 2022

Abstract
Back-to-back dijet cross-sections in deeply inelastic scattering (DIS) at small xBj are suppressed by many-body multiple scattering and screening effects arising from gluon saturation at high parton densities. They are similarly sensitive in these kinematics to large Sudakov logarithms from soft gluon radiation. Uncovering novel physics in this DIS channel therefore requires understanding the interplay of the two phenomena. In this work, we compute the small xBj inclusive dijet DIS cross-section in back-to-back kinematics at next-to-leading order (NLO) in the Color Glass Condensate effective field theory (CGC EFT). Our result includes, for the first time, all real and virtual NLO contributions to the impact factor. These include all Sudakov double and single logarithm contributions, as well as all other finite $$ \mathcal{O} $$
O
(αs) terms that contribute at this order. We demonstrate explicitly that resummations of small x and Sudakov logarithms can be performed simultaneously in the CGC EFT. This requires that the JIMWLK kernel for small x evolution of the Weizsäcker-Williams (WW) gluon distribution satisfies a kinematic constraint imposed by lifetime ordering of successive gluon emissions; the corresponding modifications to the kernel, corresponding to resummations of large double transverse logarithms, are precisely of the type required to stabilize JIMWLK evolution beyond leading logarithmicaccuracy. We compute the azimuthal harmonics of the NLO back-to-back distributions and show their sensitivity to both the unpolarized and linearly polarized WW gluon distributions. Finally, we discuss how TMD factorization is broken by an emergent saturation scale at small x.
Intermittent thoracic resuscitative endovascular balloon occlusion of the aorta improves renal function compared to 60 min continuous application after porcine class III hemorrhage
Authors: Brännström Andreas , Hultström Michael , Gustavsson Jenny , Aurfan Zabih , Günther Mattias 
Published: December 2022

Abstract
Background
Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be considered for stabilization of patients with hemorrhage from below the diaphragm. Occluding the aorta is a powerful means of hemorrhagic control but is also associated with acute kidney injury, which increases mortality in trauma patients. Allowing for intermittent distal blood flow during REBOA application (iREBOA) could decrease this risk, but circulatory consequences have not been sufficiently elucidated. Therefore, we investigated circulatory effects and the renal artery blood flow (RBF) in iREBOA versus continuous, complete aortic occlusion (cREBOA).

Methods
In a porcine model of uncontrolled class III hemorrhage (34% estimated total blood volume, mean 1360 mL), swine (n = 12, mean weight 60.3 kg) were randomly assigned to iREBOA: 3-min full deflation every 10 min (n = 6), or cREBOA (n = 6), for 60 min of thoracic (zone I) application. The animals then underwent 60 min of reperfusion (critical care phase).

Results
Survival was 100% in iREBOA and 83% in cREBOA. The intermittent balloon deflation protocol was hemodynamically tolerable in 63% of reperfusion intervals. Systolic blood pressure decreased during the reperfusion intervals in iREBOA animals (mean 108 mm Hg versus 169 mm Hg; p < 0.005). No differences were detected in heart rate, cardiac output or stroke volume between methods. Troponin I increased in cREBOA after 60 min (mean 666–187 ng/L, p < 0.05). The norepinephrine requirement increased in cREBOA during reperfusion (mean infusion time 12.5–5.5 min; p < 0.05). Total ischemic time decreased in iREBOA (60.0–48.6 min; p < 0.001). RBF increased in iREBOA during balloon deflations and after 60 min reperfusion (61%–39% of baseline RBF; p < 0.05). Urine output increased in iREBOA (mean 135–17 mL; p < 0.001). Nephronal osteopontin, a marker of ischemic injury, increased in cREBOA (p < 0.05).

Conclusion
iREBOA was survivable, did not cause rebleeding, decreased the total ischemic time and increased the renal blood flow, urine output and decreased renal ischemic injury compared to cREBOA. Intermittent reperfusions during REBOA may be preferred to be continuous, complete occlusion in prolonged application to improve renal function.

Published: December 2022

AbstractPurposeThe purpose of the study was the clinical evaluation of the capsular management with arthroscopic treatment of femoroacetabular impingement and labral tears by comparing the functional outcomes of closed versus open capsule.MethodsPatients with a median age of 38 years (18–55), clinical and radiological features of FAI and/or labral tear, and non‐arthritic non‐dysplastic hips were selected for arthroscopic treatment. Capsulotomy was performed primarily as an interportal section, then a distal extension preserving the zona orbicularis was added. The study compared two matched groups: patients with open capsule versus patients with closed capsule. Clinical outcomes were assessed by Non‐Arthritic Hip Score, hip outcome scores of daily living activities and sports‐specific scales. Scores were collected preoperatively and 6 months, 2 years and 5 years postoperatively. Rate of revision arthroscopy and conversion to total hip arthroplasty were used for comparing groups. Minimal clinically important differences were calculated for both groups.ResultsThe study included 42 patients in the OC group and 44 patients in the CC group. Significant improvement of postoperative PROMs was recorded in both groups compared to preoperative scores. CC group significantly improved more than the OC group based on NAHS, HOS‐ADL and HOS‐SSS over all check points except for NAHS and HOS‐ADL at 6 months, which were statistically non‐significant. A non‐significant difference was observed in the percentage of patients who met the MCID for all reported outcome scores at 5 years in both groups. The rate of reoperation was similar in both groups, but with different indications.ConclusionArthroscopic treatment of FAI and labral repair with complete closure of the hip capsule led to significantly improved functional outcomes after 5 years follow‐up compared with open capsule. Closed capsule can provide greater improvement in the sports‐specific outcomes at early follow‐up. Controlled capsulotomy limited by zona orbicularis did not produce instability at any postoperative stage. Similar proportions of patients achieved minimal clinically important difference, and similar rates of reoperation were reported in both groups.Level of evidenceIII
Newtonian (moving mass) calibration of tilt and gravity meters and the investigation of some factors influencing its accuracy
Authors: Papp Gábor , István Csáki Dániel , Benedek Judit 
Published: December 2022

AbstractThe idea of moving mass calibration (MMC) of relative gravity meters dates back to the seventies of the last century. Probably the MMC apparatus built in the underground Mátyáshegy Gravity and Geodynamics Laboratory Budapest has been used most extensively and several spring type instruments (LaCoste and Romberg and Scintrex) have been investigated and calibrated by it. Its test mass is a cylindrical ring having a weight of 3 tons. Its main advantage is simplicity in terms of metrology. The same principle and technology can be used to test compact tilt sensors having nanoradian resolution capability. Up to now rigorous testing methods below microradian range were not available in practice. The analysis of the so-called off-axis variation of the gravitational vector generated by the vertical movement of the cylindrical ring mass of the Mátyáshegy MMC device, however, showed that a sufficiently accurate reference signal having (15 ± 0.02) nrad peak-to-peak amplitude can be provided for calibration. It is just in the range of tilt induced by earth tide effect, which is a “standard” signal component in the time series recorded in observatory environment. In the first part of the paper, a discussion of the proposed methodology of tilt meter calibration is given. Then the analysis of the effect of volumetric discretization of the cylindrical ring on the accuracy of calibration is provided. Finally, possible material inhomogeneities of the ring mass and their gravitational effects are investigated by forward simulations and inversion. For this purpose the results of 300 gravimeter calibration experiments, analysed and published earlier, were utilized.

Elliptic Solutions of Boussinesq Type Lattice Equations and the Elliptic $$N{\textrm{th}}$$ Root of Unity
Authors: Nijhoff Frank W. , Sun Ying-ying , Zhang Da-jun 
Published: December 2022

AbstractWe establish an infinite family of solutions in terms of elliptic functions of the lattice Boussinesq systems by setting up a direct linearisation scheme, which provides the solution structure for those equations in the elliptic case. The latter, which contains as main structural element a Cauchy kernel on the torus, is obtained from a dimensional reduction of the elliptic direct linearisation scheme of the lattice Kadomtsev–Petviashvili equation, which requires the introduction of a novel technical concept, namely the ‘elliptic cube root of unity’. Thus, in order to implement the reduction we define, more generally, the notion ofelliptic$$N{\textrm{th}}$$Nthroot of unity, and discuss some of its properties in connection with a special class of elliptic addition formulae. As a particular concrete application we present the class of elliptic multi-soliton solutions of the lattice Boussinesq systems.

AbstractNonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. Nonalcoholic steatohepatitis (NASH) is an advanced form of NAFLD can progress to liver cirrhosis and hepatocellular carcinoma (HCC). Recently, the prognosis of NAFLD/NASH has been reported to be dependent on liver fibrosis degree. Liver biopsy remains the gold standard, but it has several issues that must be addressed, including its invasiveness, cost, and inter-observer diagnosis variability. To solve these issues, a variety of noninvasive tests (NITs) have been in development for the assessment of NAFLD progression, including blood biomarkers and imaging methods, although the use of NITs varies around the world. The aim of the Japan NASH NIT (JANIT) Forum organized in 2020 is to advance the development of various NITs to assess disease severity and/or response to treatment in NAFLD patients from a scientific perspective through multi-stakeholder dialogue with open innovation, including clinicians with expertise in NAFLD/NASH, companies that develop medical devices and biomarkers, and professionals in the pharmaceutical industry. In addition to conventional NITs, artificial intelligence will soon be deployed in many areas of the NAFLD landscape. To discuss the characteristics of each NIT, we conducted a SWOT (strengths, weaknesses, opportunities, and threats) analysis in this study with the 36 JANIT Forum members (16 physicians and 20 company representatives). Based on this SWOT analysis, the JANIT Forum identified currently available NITs able to accurately select NAFLD patients at high risk of NASH for HCC surveillance/therapeutic intervention and evaluate the effectiveness of therapeutic interventions.
