Sensitivity of ECMWF coupled forecasts to improved initialization of the ocean mesoscale
Authors: Roberts Christopher D. , Balmaseda Magdalena A. , Tietsche Steffen , Vitart Frederic 
Published: October 2022

AbstractIt has been hypothesized that initial conditions derived from eddy‐resolving ocean models could benefit eddy‐permitting forecast systems at subseasonal lead times (2 weeks to 2 months) by providing improved ocean initial conditions and reduced sea‐surface temperature (SST) errors associated with a more realistic representation of mesoscale features and ocean fronts such as the Gulf Stream. Here, we test this hypothesis by running a series of coupled 32‐day reforecasts with ocean initial conditions derived from native resolution (i.e., eddy‐permitting) and higher resolution (i.e., eddy‐resolving) ocean reanalyses. Initial conditions derived from the eddy‐resolving reanalysis reproduce observed temperature and sea‐level variability associated with mesoscale ocean eddies more accurately. Furthermore, forecasts of ocean variables are significantly improved in the extratropics, particularly in regions of observed intense mesoscale variability. This result is relevant for the marine forecasting community and demonstrates the potential for improved probabilistic forecasts of ocean variables in affordable ensemble forecast systems. However, the impacts on the mean state and forecast skill in the atmosphere are more limited. Based on an evaluation of model biases as a function of lead time, we conclude that there is room for further improvements to the initialization of the Gulf Stream that could lead to more significant impacts on atmospheric skill. Furthermore, we demonstrate that our reforecasts underestimate the strength of mesoscale air–sea interaction in the vicinity of strong SST fronts by 20–40%. We speculate that the impacts of improved ocean eddy initialization on atmospheric forecast skill may be larger in coupled models with higher ocean and atmosphere resolutions that can simulate air–sea interaction in the midlatitudes more realistically.
Efficient Broadband Frequency Conversion via Shortcuts to Adiabaticity
Authors: Paul Koushik , Kong Qian , Chen Xi 
Published: October 2022

AbstractThe method of adiabatic frequency conversion, in analogy with a two‐level atomic system, has been put forward recently and verified experimentally to achieve robust frequency mixing processes such as sum and difference frequency generation. Here a comparative study of efficient frequency mixing using various techniques of shortcuts to adiabaticity such as counter‐diabatic driving and invariant‐based inverse engineering is presented. It is shown here that it is possible to perform sum frequency generation by properly designing the poling structure of a periodically poled crystal and the coupling between the input lights and the crystal. The required crystal length for frequency conversion significantly decreases beyond the adiabatic limit. This approach significantly improves the robustness of the process against the variation in temperature as well as the signal frequency. By introducing a single parameter control technique with constant coupling and combining with the inverse engineering, perturbation theory, and optimal control, it is shown that the phase mismatch can be further optimized with respect to the fluctuations of input wavelength and crystal temperature that results into a novel experimentally realizable mixing scheme.
Is the Carbon Nanotube‐Catalyst Interface Clean during Growth?
Authors: Qiu Lu , Ding Feng 
Published: October 2022

AbstractRevealing a “true” picture of the carbon nanotube (CNT) growth front at the catalyst surface is critical to understanding the mechanism of CNT growth. If the CNT‐catalyst interface is clean or messy, which will greatly affect the mechanism of controlled CNT growth, has never been properly solved either experimentally or theoretically. Here, this issue by ab initial calculation‐based kinetic analysis and classical molecular dynamic (MD) simulations is revisited. It is found that the appearance of carbon chains at the CNT‐catalyst interfaces or the “messy” interfaces in MD simulations is a consequence of the very short simulation time, and a “clean” CNT‐catalyst interface will emerge if the simulation time is close to that in real experiments. This study reveals that, during real CNT experimental growth, a “clean” CNT‐catalyst interface with zigzag, armchair, and/or kink sites dominates the growth kinetics, and therefore, the controllable CNT growth by tuning the CNT‐catalyst interface is feasible.
Yuan‐Shengdialectical holism and systems thinking: A systemism research tradition that integrated Chinese and Western holism
Authors: Dongping Fan , Yiyu Liu , Linhao Chen 
Published: October 2022

AbstractFrom the perspective of Laudan's ‘research traditions’, this paper attempts to propose the ‘systemism research tradition’ (SRT) that integrates Chinese and Western holisms based on complex systems science. First, we establishYuan‐Shengdialectical holism as the ontological assumption of the SRT, emphasising that the world is a ‘relation‐centric’ system.Yuanrefers to specific time–space relations, and the becoming of the world (Sheng) fromYuanmanifests as a dialectical holistic relationship in which ‘contrary is complementary’. Second, we argue that the ontological assumption of SRT implies three methodological principles: systemhood thinking, synergistic thinking and emergent thinking. These principles focus on relations, openness, synergy, adaptation and emergence. Last but not the least, we argue that the SRT is a kind of applied systems thinking. The context‐dependent multi‐causation methodology, dealing with the sustainability of social‐ecological systems, has been successfully applied in explaining the resilience governance of Guangzhou Haizhu Wetland in China.
FemTech.dk Research Initiative
Authors: Bjørn Pernille , Menendez-Blanco Maria , Borsotti Valeria 
Published: October 2022

AbstractFemTech.dk is situated in the Department of Computer Science at University of Copenhagen Denmark and has been an ongoing inquiry into the specific circumstances within computer science that produce gender imbalance and includes activities dedicated to making a change through design interventions. FemTech.dk was created in 2016 to engage with research within gender and diversity and to explore the role of gender equity as part of digital technology design and development. FemTech.dk considers how and why computer science as a field and profession in Denmark has such a distinct unbalanced gender representation in the twenty-first century. The focus was initially on the student base of the bachelor’s program in computer science, which from the 1980s until 2016 was remarkably smaller than for other science programs at the University of Copenhagen. In terms of numbers, only 15 women students entered the bachelor’s degree program in 2012 and 2013, and only 12 women students entered the program in 2014. In each of these 3 years, more than 160 students entered the program in total. Reviewing the 15-year period 2000–2014, the share of women students in the program was 7–9%, the lowest percentage of women in a study program across all of the University of Copenhagen. To compare, in 2016 the share of women students in the Math program was 30%, and in Physics was 25%.
Cyberbear & Cryptosphere: Sociomaterial-Design, Social Belonging, and Gender Representations
Authors: Bjørn Pernille , Menendez-Blanco Maria , Borsotti Valeria 
Published: October 2022

AbstractAs digital technologies are integrated into societies, questions about who participates in technology development become increasingly crucial. When in 2016 we began FemTech, we wanted to redefine the nature of computer science in a way to reach out to people who were not already within the field – and who did not consider or see themselves as potentially successful in technology development. To make such change through interventions, in some of our first initiatives, we sought ways to create design artefacts that manifested alternative narratives of computer science while meaningfully interlinking with people outside computer science. Thus, our interest was to strive for gender equity in computing with an impact not only on educational programs but also on the underlying structures and society, through opening educational programs in alternative ways.
Approach for Evaluating Changeable Production Systems in a Battery Module Production Use Case
Authors: Fries Christian , Hölscher Patricia , Brützel Oliver , Lanza Gisela , Bauernhansl Thomas 
Published: October 2022

AbstractVolatile markets continue to complicate manufacturing companies’ production system design, leading to efficiency losses due to imperfect system setups. In such a market environment, a perfect system setup cannot be achieved. Therefore, changeable production systems that cope with immanent uncertainty gain interest in research and industry. For several decades, changeable production systems have been in the research and development stage. The advantages and disadvantages are well investigated. So far, however, they have gained only limited acceptance in industry. One of the reasons is the difficult evaluation of the benefits. Existing investment calculation methods either neglect many effects of changeability, such as easier adaptation to unpredictable events, or are too complex and therefore too time-consuming to become standard. Thus, a practical evaluation method is needed that considers these changeability aspects. This paper deviates the industry requirements regarding an evaluation method based on an industry survey and develops a practical approach for an evaluation method for a changeable production system considering monetary and non-monetary aspects. The approach is characterized by a calculation that is as accurate as possible considering the existing input factors. The method shows that changeable production systems excel in environments with frequent need for adaptation. The approach is applied to a battery module assembly in the ARENA2036 research campus.
Effect of Ultrasonic Burnishing Parameters on Burnished-Surface Quality of Stainless Steel After Heat Treatment
Authors: Ullah Rizwan , Fangnon Eric , Huuki Juha 
Published: October 2022

AbstractUltrasonic burnishing induces beneficial compressive stresses and high surface quality in components with contact as a functional requirement. It was observed in previous work that some burnishing parameters can hinder burnishability of stainless steels. In this research tangential misalignment angles (TMA) for burnishing were varied considering as-supplied and heat-treated stainless steel. Properties such as surface hardness and surface roughness were measured after burnishing process. Electron Backscatter Diffraction was performed to characterize microstructure using Matlab (MTEX) to calculate average grain areas. By changing burnishing parameters, i.e., shaft rotational speed and burnishing tool diameter, it was observed that burnishing was less successful. Nevertheless, significant improvement in burnished surface quality was observed after heat-treatment process. In addition, grain size characterization revealed mean grain area reduction from 26 µm2 for unburnished to 11 µm2 and 3 µm2 for burnished and heat-treated samples respectively. Most importantly this work reveals the enhanced possibility of burnishing stainless steels after heat-treatment with varying tangential misalignment angles.
Modelling and Simulation of Automated Hydraulic Press Brake

Published: October 2022

AbstractIn this study, a reconfigurable hydraulic press brake was designed using Solidworks and simulated on a hydraulic Automation Studio Fluidsim. The designed press brake comprises of the frame balance, conveyor rollers and support, belt, chuck, six hydraulic cylinders assembled with bolts and nuts. The buckling force was determined analytically and compared with the Finite Element Analysis (FEA) simulation to prevent distortion of length and section. The Von mises stress theory was used to determine the stress, resultant load and displacement. The results obtained from the FEA simulation were compared with the mechanical properties of the hydraulic press brake. The maximum stress induced is significantly lower than the tensile strength of the hydraulic press brake. Hence, the stress induced due to bending cannot cause the cast alloy to yield. Also, the buckling force significantly exceeds the resultant force giving no chances for buckling. The designed hydraulic press brake is flexible enough to control using hydraulic cylinders and enhances sufficient strength and rigidity during clamping and loading conditions.

Removal of conical singularities from rotating C-metrics and dual CFT entropy
Authors: Astorino Marco 
Published: October 2022

Abstract
We show how to remove from the rotating C-metric spacetime, which describes accelerating Kerr black holes, both conical singularities. This can be done by embedding the metric into a swirling gravitational universe, through a proper Ehlers transformation. The spin-spin interaction between the external rotational background and the black hole provides the source of the acceleration without the need of rods or strings. The physical properties and entropy of the new solution are studied using near horizon and dual conformal techniques of the Kerr/CFT correspondence. The charged case is also analysed: accelerating Reissner-Nordstrom and Accelerating Kerr-Newman space-times embedded in a swirling universe are also generated.
On supersymmetric interface defects, brane parallel transport, order-disorder transition and homological mirror symmetry
Authors: Galakhov Dmitry 
Published: October 2022

Abstract
We concentrate on a treatment of a Higgs-Coulomb duality as an absence of manifest phase transition between ordered and disordered phases of 2d $$ \mathcal{N} $$
N
= (2, 2) theories. We consider these examples of QFTs in the Schrödinger picture and identify Hilbert spaces of BPS states with morphisms in triangulated categories of D-brane boundary conditions. As a result of Higgs-Coulomb duality D-brane categories on IR vacuum moduli spaces are equivalent, this resembles an analog of homological mirror symmetry. Following construction ideas behind the Gaiotto-Moore-Witten algebra of the infrared one is able to introduce interface defects in these theories and associate them to D-brane parallel transport functors. We concentrate on surveying simple examples, analytic when possible calculations, numerical estimates and simple physical picture behind curtains of geometric objects. Categorification of hypergeometric series analytic continuation is derived as an Atiyah flop of the conifold. Finally we arrive to an interpretation of the braid group action on the derived category of coherent sheaves on cotangent bundles to flag varieties as a categorification of Berry connection on the Fayet-Illiopolous parameter space of a sigma-model with a quiver variety target space.

Published: October 2022

Abstract
Purpose
Severe haemorrhage is a leading cause of early mortality following major trauma. By early identification of patients at risk, blood transfusion could already be initiated in the prehospital period. Aim of the study was to evaluate the extent to which prehospital lactate and base excess, which are known to be associated with trauma-induced coagulopathy, and additional clinical parameters are associated with the need for early transfusion.

Methods
In this prospective, single-centre observational study, trauma patients treated by a helicopter emergency medical service were included, regardless of the injury severity. Patients with coagulation-influencing drugs in long-term therapy were excluded. Blood samples obtained at the beginning of the prehospital treatment were analysed. Primary outcome was the association of lactate and base excess with the need for early transfusion (resuscitation room or immediate surgery). Receiver operating characteristic curves were created, and the area under the curve (AUROC) was calculated.

Results
Between 2015 and 2018, 21 out of 130 adult trauma patients received blood products during the early in-hospital treatment. Both prehospital lactate and base excess were associated with the transfusion (AUROC 0.731 and 0.798, respectively). The optimal calculated cut-off values were 4 mmol/l (lactate) and − 2.5 mmol/l (base excess). When circulatory instability and suspected relevant bleeding were included, the association further improved (AUROC 0.871 and 0.866, respectively).

Conclusion
Prehospital lactate and base excess could be used in combination with other clinical parameters as indicators of the need for early transfusion. This relationship has yet to be confirmed in the current validation study.

Efficient management of industrial electric vehicles by means of static and dynamic wireless power transfer systems

Published: October 2022

AbstractIndustrial companies are moving toward the electrification of equipment and processes, in line with the broader energy transition taking place across the economy. Particularly, the energy efficiency and, consequently, the reduction of environmental pollution of intralogistics activities have become a competitive element and are now an actual research and development objective. A wireless power transfer is a contactless electrical energy transmission technology based on the magnetic coupling between coils installable under the ground level and a coil mounted under the vehicle floor, and it represents an excellent solution to decrease the demand for batteries by reducing vehicle downtimes during the recharge. This work aims to define a methodology to determine the optimal positioning of wireless charging units across the warehouse, both for static and dynamic recharging. To this aim, firstly, a mathematical model of the warehouse is proposed to describe transfers and storage/retrieval operations executed by the forklifts. Then, an integer linear programming problem is applied to find the best possible layout of the charging infrastructures. The optimal solution respects the energetic requirements given by the customer and minimizes the overall system cost. The proposed approach was applied to optimize the installation in a real-size warehouse of a tire manufacturing company. Several scenarios were computer generated through discrete event simulation in order to test the optimizer in different warehouse conditions. The obtained results show that integrated dynamic and static WPT systems ensure a constant state of charge of the electric vehicles during their operations.
Hemidystonia secondary to pediatric thalamic glioblastoma: a case report
Authors: Wolff Fernandes Filipe , Saryyeva Assel , Ertl Philipp , Krauss Joachim Kurt 
Published: October 2022

Abstract
Introduction
Thalamic tumors are rare and uncommonly manifest as movement disorders, including hemidystonia. Despite this association, little is known about the evolution of hemidystonia.

Case description
We report on a 11-year-old boy who complained of hypaesthesia and fine motor problems in the left hand. A magnetic resonance imaging showed a large mass in the right thalamus. Stereotactic biopsy revealed a WHO grade 4 astrocytoma, and the patient underwent normofractioned radiochemotherapy with proton-beam radiation and temozolomide. Three months later, a spastic hemiparesis developed on the left side, which progressed over months. Over the following months, the hemiparesis slowly improved, but hemidystonia in the same side developed. This was accompanied with radiological evidence of tumor regression, showing a persistent lesion in the ventral posterolateral and the intralaminar thalamus.

Conclusion
This case illustrates the unusual and complex temporal course of appearance and disappearance of hemidystonia along with the regression and growth in glioblastoma involving the thalamus.
Signatures of midsummer droughts over Central America and Mexico
Authors: Zhao Zijie , Han Meng , Yang Kai , Holbrook Neil J. 
Published: October 2022

AbstractThe annual cycle of precipitation over most parts of Central America and southern Mexico is climatologically characterized by a robust bimodal distribution, normally termed as the midsummer drought (MSD), influencing a large range of agricultural economic and public insurances. Compared to studies focusing on mechanisms underpinning the MSD, less research has been undertaken related to its climatological signatures. This is due to a lack of generally accepted methods through which to detect and quantify the bimodal precipitation accurately. The present study focuses on characterizing the MSD climatological signatures over Central America and Mexico using daily precipitation observations between 1979 and 2017, aiming to provide a comprehensive analysis of MSD in fine scale over this region. This was completed using a new method of detection. The signatures were analyzed from three aspects, namely (1) climatological mean states and variability; (2) connections with large scale modes of climate variability (El Niño–Southern Oscillation (ENSO) and the Madden–Julian Oscillation (MJO)); and (3) the potential afforded by statistical modelling. The development of MSDs across the region is attributed to changes of surface wind–pressure composites, characterized by anomalously negative (positive) surface pressure and onshore (offshore) winds during the peak (trough) of precipitation. ENSO’s modulation of MSDs is also shown by modifying the surface wind–pressure patterns through MSD periods, inducing the intensified North Atlantic Subtropical High and associated easterlies from the Caribbean region, which induce relatively weak precipitation at corresponding time points and subsequently intensify the MSD magnitude and extend the MSD period. Building on previous research which showed MSDs tend to start/end in MJO phases 1 and 8, a fourth–order polynomial was used here to statistically model the precipitation time series during the rainy season. We show that the strength of the bimodal precipitation can be well modelled by the coefficient of the polynomial terms, and the intra-seasonal variability is largely covered by the MJO indices. Using two complete MJO cycles and the polynomial, the bimodal precipitation during the rainy season over Central America and Mexico is synoptically explained, largely contributing to our understanding of the MJO’s modulation on the MSD.
