Predicting object properties based on movement kinematics
Authors: Kopnarski Lena , Lippert Laura , Rudisch Julian , Voelcker-Rehage Claudia 
Published: November 2023

AbstractIn order to grasp and transport an object, grip and load forces must be scaled according to the object’s properties (such as weight). To select the appropriate grip and load forces, the object weight is estimated based on experience or, in the case of robots, usually by use of image recognition. We propose a new approach that makes a robot’s weight estimation less dependent on prior learning and, thereby, allows it to successfully grasp a wider variety of objects. This study evaluates whether it is feasible to predict an object’s weight class in a replacement task based on the time series of upper body angles of the active arm or on object velocity profiles. Furthermore, we wanted to investigate how prediction accuracy is affected by (i) the length of the time series and (ii) different cross-validation (CV) procedures. To this end, we recorded and analyzed the movement kinematics of 12 participants during a replacement task. The participants’ kinematics were recorded by an optical motion tracking system while transporting an object, 80 times in total from varying starting positions to a predefined end position on a table. The object’s weight was modified (made lighter and heavier) without changing the object’s visual appearance. Throughout the experiment, the object’s weight (light/heavy) was randomly changed without the participant’s knowledge. To predict the object’s weight class, we used a discrete cosine transform to smooth and compress the time series and a support vector machine for supervised learning from the achieved discrete cosine transform parameters. Results showed good prediction accuracy (up to $$95\%$$

Abstract
Background
Robot-assisted total hip arthroplasty (RA-THA) improves accuracy in achieving the planned acetabular cup positioning compared to conventional manual THA (mTHA), but optimal dosage for peri-RA-THA and mTHA pain relief remains unclear. This study aimed to compare pain control with opioids between patients undergoing direct anterior approach THA with the use of a novel, fluoroscopic-assisted RA-THA system compared to opioid consumption associated with fluoroscopic-assisted, manual technique.

Methods
Retrospective cohort analysis was performed on a consecutive series of patients who received mTHA and fluoroscopy-based RA-THA. The average amount of postoperative narcotics in morphine milligram equivalents (MME) given to each cohort was compared, including during the in-hospital and post-discharge periods. Analyses were performed on the overall cohort, as well as stratified by opioid-naïve and opioid-tolerant patients.

Results
The RA-THA cohort had significantly lower total postoperative narcotic use compared to the mTHA cohort (103.7 vs. 127.8 MME; P < 0.05). This difference was similarly seen amongst opioid-tolerant patients (123.6 vs. 181.3 MME; P < 0.05). The RA-THA cohort had lower total in-hospital narcotics use compared to the mTHA cohort (42.3 vs. 66.4 MME; P < 0.05), consistent across opioid-naïve and opioid-tolerant patients. No differences were seen in post-discharge opioid use between groups.

Conclusions
Fluoroscopy-based RA-THA is associated with lower postoperative opioid use, including during the immediate perioperative period, when compared to manual techniques. This may have importance in rapid recovery protocols and mitigating episode burden of care.
Beamforming: a spatial de-noising approach for civil structural health monitoring
Authors: Wang Zihang , Ren Yuan , Deng Chao , Zhong Wenzhe 
Published: November 2023

AbstractIn the civil structural health monitoring fields, monitored data suffer from noise and sensor faults. In practice, redundant sensors are usually deployed to monitor structural condition to obtain more accurate and robust information. This paper proposes a beamforming-based spatial filtering method to improve the data quality by using the information redundancy within sensor networks. Data pre-processing is first implemented, including missing data imputation and thermal response separation. Subsequently, short-term Fourier transform is used to transform the measured time sequences into time–frequency domain to obtain more useful features. Finally, signals in the time and frequency domain are processed using the beamforming algorithm. In the beamformers, a linear filter is applied to suppress noise signals, which is formulated as a constrained optimization problem. Herein, interior point algorithm is used to optimize the allocation of the linear filter, wherein the objective function is to minimize the power of the noise component at the beamformer output. The effectiveness of the proposed method is verified by using signals from strain gauges installed on steel deck plates of the 3rd Nanjing Yangtze River Bridge. Results through the case study show that signals after spatial filtering have a satisfactory de-noising, which indicates the effectiveness of the proposed beamforming algorithm. We believe that the proposed beamforming algorithm has substantial potential applications, such as providing high quality data source for further investigations.

Uncontrolled Overspeed
Authors: Andrew Phil 
Published: November 2023

The major part of the design and specification of equipment for the arrest or prevention of overspeed, particularly the safety gear/overspeed governor combination, concerns itself with the performance when carrying rated load, or, in the event of upward overspeed, zero load in the car. In particular, specification is concerned with performance of safety equipment in the face of suspension failure, however unlikely that might be. This paper sets out to investigate the performance of overspeed protection when there is a partial load in the car, whether with a failed suspension or not, and to discuss the opportunities in this respect provided by the introduction of the so-called rope brake.

Published: November 2023

ABSTRACT
Understanding the potential adverse effects associated with oncological treatments is crucial in the clinical care of patients with cancer. We describe the first case report delineating severe acute liver injury secondary to axitinib. This is a case of metastatic renal cell carcinoma treated with axitinib and pembrolizumab, complicated by a severe axitinib-induced liver injury, characterized by significant elevations of hepatocellular and cholestatic liver enzymes during initial treatment and rechallenge of axitinib. Remarkably, the liver chemistries normalized upon discontinuation of the medication.

Published: November 2023

Abstract
Extended end-plate type connections are widely utilized in steel assemblies for easy production and assembly. The proper end-plate and bolt selection is paramount to confirming safety and economy in all connections and, consequently, steel buildings. This study presented an approach for refined parametric three-dimensional finite element analysis of bolted steel beam-to-beam extended end-plate connections. The model considers geometrical and material non-linearity to determine the impact of various factors on the connection’s performance. The proposed model was used to construct a parametric study. The study variables were bolt diameter and end-plate thickness, focusing on how thick and thin end plates affect connection conductivity. Numerical outcomes demonstrate that the connection's flexural strength and stiffness capability improved by increasing the end-plate thickness and bolt diameter. Finally, the analysis results were assessed, and the main conclusions were presented.
Der Euromarkt und die Internationalisierung der deutschen Banken
Authors: Kopper Christopher 
Published: November 2023

Abstract
The tax exemption of interest revenues and the high level of professional secrecy were the unique selling points of Luxembourg for the German banking community. From the 1960s to the 1990s, they were the main causes for the rise of Luxembourg to one of the biggest euromarket places. The government of Luxembourg used these institutional factors to foster and accelerate the economic transformation from an industrial to a post-industrial country. The German banks did not reduce or even discontinue their presence in Luxembourg after the end of tax exemption and strict banking secrecy. Instead, they specialized on syndicated loans, treasury functions and Private Wealth Management for wealthy clients.
Commercial Banking from Oil Crisis to Debt Crisis: The Case of Lloyds Bank
Authors: Altamura Carlo Edoardo 
Published: November 2023

Abstract
In January 1998, the British weekly The Economist called the British bank Lloyds a “money machine”. Such an outcome was far from inevitable for a bank that had been one of the hardest hit victims of the 1982 sovereign debt crisis, when most developing countries found themselves unable to repay debts accumulated over the course of the 1970s. Having overextended itself in the developing world, it took Lloyds more than a decade to return to profitability. This result was the consequence of a complete transformation of the bank’s business and management model. Branches and international loans were sidelined, as was the investment banking business, deciding to focus its activities on domestic banking. The article analyses the reasons behind the transformation of Lloyds Bank from a national bank to an international power in the 1970s and, therefore, the reverse process between the 1980s and 1990s following the sovereign debt crisis. Thanks to the examination of archival documents recently opened for consultation, the article sheds new light on various issues analysed from banking and business history, in particular on how risk is calculated, how innovative decisions are made in a context of crisis and on the role of managers in shaping and changing the culture of these institutions.
Lockvogelangebote und Rabattschlachten: Der Bierverkauf des Lebensmitteleinzelhandels in den 1970er und 1980er Jahren
Authors: Bodden Nancy 
Published: November 2023

Abstract
Previously undiscovered market studies show that the sale of beer as a loss-leader offer was already used as a competitive tool in food retailing in the 1970s and became an important feature of aggressive competition among retailers in the 1980s. The article illustrates the specific assortment and pricing policies in beer retailing and makes clear that increasing beer sales at low dumping prices led to profit losses for the stores.
This highlights another facet in the development of the West German mass consumer society and the structural change in food retailing: the hallmarks of the growth and concentration process were not only the procurement and financing advantages of the large retailers, but also loss-leader offers and price undercutting in certain product groups, of which beer was demonstrably one.
War, Risk, and Gold: The Turkish War of Independence and Ottoman Empire
Authors: Hanedar Avni Önder 
Published: November 2023

Abstract
After the end of the First World War in November 1918, the Allies were involved in a military campaign in the Ottoman lands, leading to a national resistance by Turks that would end in 1923. It is relevant to provide actual information on the outcomes of the Turkish War of Independence, since it was a longlived event that paved the way for further problems on the belligerents’ economies. Using unique data for the value of the gold from 1919 to 1925 at the İstanbul bourse, our analysis complements the historical arguments as historians may find political risks difficult to quantify. We observe that in 1921 the Turkish victories created expectations on the part of traders that the war could end soon, as is manifested in exchange rate fluctuations. The Turkish economy would have experienced higher financial instability with the Allies’ occupation and resistance in 1920, creating a lower chance to return the pre-war gold content of the belligerents’ currencies.
Ultraviolet light scattering by a silicon Bethe hole
Authors: Lee Dukhyung , Lee Youjin , Kim Dai-Sik 
Published: November 2023

Abstract
Bethe’s theory predicts that scattering by a small hole on a thin perfect electric conductor (PEC) is presented as radiation by an in-plane magnetic dipole of the incident magnetic field direction. Even in the near-infrared range where metals are no more PEC, the magnetic dipole radiation of Bethe holes has been demonstrated. However, such Bethe holes’ nature has not been addressed yet in the ultraviolet (UV) range where conductivity of metals becomes severely deteriorated. Meanwhile, UV plasmonics has been elevating its importance in spectroscopy and photochemistry, recognizing silicon (Si) as an alternative plasmonic metal featuring the interband transition in the UV range. In this work, we expanded the Bethe’s theory’s prediction to the UV range by investigating Si Bethe holes theoretically and experimentally in terms of the scattering pattern and polarization. Simulation results showed that the scattered field distribution resembles that of an in-plane magnetic dipole, and the dipole direction at oblique incidence is roughly given as the incident magnetic field direction with a deviation angle which can be predicted from the Fresnel equations. Simulation with various diameters showed that the magnetic dipole nature maintains with a diameter less than the quarter-wavelength and multipoles becomes noticeable for diameters larger than the half-wavelength. We performed scattering polarization measurement at 69-degree incidence, which confirms the theoretical analysis. The features of Si Bethe holes demonstrated here will be useful for designing UV plasmonic metasurfaces.

Published: November 2023

The Jbel Zerhoun region is a geographical entity whose features create a wholly unique natural environment full of aromatic and therapeutic plants. In this work, we represent the study of malacological diversity on five lamiaceae abundant in the region, which are horehound, thyme, sage, lavender and spearmint. The results of the study showed a malacological richness of 13 species on spearmint, 12 species on thyme, 11 species on sage, 10 species on lavender with only 3 species on horehound. The different species belong to four families, which are Parmacellidae, Milacidae, Sphincterochilidae, Helcidae and Subulinidae. The Helicidae family is the most abundant with 10 species ; the Otala genus is the most represented on the different plants with the exception of horehound. The Parmacellidae family represented by the Parmacella deshayesi species is present only on spearmint, the Milicidae represented by Milax gagates is present on four plants, and absent on thyme, the species albea candidissima of the family Sphincterochilidae is present on four lamiaceae, absent on horehound. Rumina decollata is the only species of the Subulinidae family, which is present on all the plants studied with Theba pissana of the Helicidae family. The vertical distribution of the different species is presented at the end of the study.

As it is important for the Blood transfusion to be extremely safe, some measures have to be taken long safeguarded the blood supply from the major transfusion transmissible diseases (TTIs). The risk of transfusion-transmitted infection (TTI) rises with the number of donors exposed, and the effects of TTI are frequently more severe in immune compromised people. TTIs (hepatitis B virus [HBV], HIV, and hepatitis C virus [HCV]) are examples of typical transfusion-transmitted infectious agents. As a result of the gradual application of nucleic acid-amplification technology (NAT) screening for HIV, HCV, and HBV, the residual risk of infected window-period donations has been minimized. Nonetheless, infections emerge far more frequently than is commonly acknowledged, needing ongoing surveillance and individual assessment of transfusion-associated risk. Although there is a constant need to monitor present dangers owing to established TTI, the ongoing issues in blood safety are mostly related to surveillance for developing agents, as well as the creation of quick reaction systems when such agents are detected.

Published: November 2023

The treatment of impacted teeth requires an interdisciplinary approach, in which early diagnosis avoids later complications. The frequency of canine retention, especially of the lower canines, has a 0.22 % average in the general population. Case information: A 9.1-year-old patient presented Lepto/Lepto, Lepto; distocclusion due to retrognathism and maxillary protrusion with left condylar asymmetry and preferential chewing on the right side. The patient also presented a structural open bite (Lower Go 78°) hyper-divergence level 4; severe crowding with complete lack of space for tooth 33, and alteration of the eruption corridor of tooth 43. Objective: Stimulate jaw growth to correct distocclusion, stimulate transversal development to gain space and eliminate crowding, and exercise traction on the lower right canine to position it correctly and correct asymmetry. Methods: A series of functional orthopedics devices were used. A Standard Bimler during the first 6 months, subsequently, Simões Network 1 (SN1) to conquer space and initiate traction, followed by the use of an SN11 to correct asymmetry with contra attachment for de-rotation and a lingual S spring. Results: It was possible to obtain incisive contact and align the anteroinferior segment, full space was obtained for tooth 33. Traction of tooth 43 was achieved and thus asymmetry was controlled. Conclusions: Functional orthopedic techniques are an effective form of dental traction that favors treatment from different perspectives. On one hand, it allows to gain space to eliminate crowding. On the other hand, it does not affect neighboring or antagonist teeth because the anchorage is not on the teeth, and it is not necessary to place intraosseous mini-implants. Also, an adequate surgical and functional orthopedic procedure makes it possible to traction the impacted teeth, orienting them to erupt and occupy the correct position in the dental arch.
Science as an Adventure: The Creative Life of Bill Hamilton
Authors: Segerstrale Ullica 
Published: November 2023

Half a century ago the paper by graduate student William Donald “Bill” Hamilton, “The Genetical Evolution of Social Behaviour” (1964), started a paradigm shift in science. That paper showed how basic social behaviors – selfishness, altruism, cooperation, and spite – could be expressed in the language of population genetics, thus opening the door to mathematical model building and testing. He showed especially that altruism can evolve as long as the benefit of an altruistic act falls on a genetically related individual rather than on a random member of a population. Later Hamilton, ever the pioneer, was to open up many other new research fields. But his ideas were often too novel and he had a hard time convincing journal referees. What they did not know was the range of methods by which he privately arrived at his conclusions: from “external” naturalistic exploration and mathematical modeling to “internal” anthropomorphic understanding of the study object, to a knowledge state that involved a veritable merger between observer and observed. Colorful computer simulation became the natural mediator between his naturalistic, esthetic and mathematical talents. Brazil played a huge liberating and stimulating role in Hamilton’s life and it became his home abroad, away from his serious Oxford professor persona. He was especially intrigued by the evolutionary puzzles of the flooded forest and helped develop ecological research in the area. The Bill Hamilton Itinerant Center for Environmental and Scientific Education at Lake Mamirauá’s floating research station was founded in his honor. Bill Hamilton was an unusual scientist who sustained an intense creativity all his life. For him, science was the best adventure there was, and Brazil was the place to be.

Abstrak
Pemberdayaan Usaha Mikro, Kecil dan Menengah (UMKM) sangat penting untuk meningkatkan ekonomi lokal. Namun, masih banyak kendala dan permasalahan dalam pemberdayaan UMKM di Indonesia. Salah satu contoh yang relavan adalah minimnya pemberdayaan UMKM di daerah kelurahan Baratajaya. Pada Perda Kota Surabaya Nomor 01 Tahun 2021 Tentang Pemberdayaan Usaha Mikro pada pasal 1 ayat 10 merupakan perancangan yang di buat untuk menyusun rangkaian pemberdayaan UMKM di daerah kota Surabaya. Kelurahan Baratajaya di pilih sebagai salah satu sampling yang menerapkan kebijakan pemberdayaan UMKM tersebut. Untuk mengukur penerapan evaluasi pemberdayaan tersebut maka di gunakanlah teori Wiliiam Dunn dengan melihat indikator efektivitas, efesiensi,kecukupan,pemerataan,responsivitas, ketepatan. Penelitian menggunakan jenis kualitatif yang berbentuk deskriptif. Hasil penelitian ini di peroleh dari Kelurahan Baratajaya menunjukan bahwa modal yang di berikan pemerintah tidak merata, kurangnya respon masyarakat dalam mengikuti sosialisasi dan pelatihan, tempat pemasaran yang kurang strategis. Kurangnya pemberdayaan UMKM berdampak pada rendahnya produktivitas, rendahnya mutu produk, dan rendahnya daya saing produk UMKM di pasar. Selain itu, UMKM juga seringkali kesulitan dalam memenuhi standar kualitas produk dan tuntutan pasar yang semakin meningkat.
