Air‐gap field prediction in tubular doubly sided surface magnet machine using Bessel–Fourier series
Authors: Javanmardi M. H. , Rahideh A. 
Published: July 2024

Abstract2‐D air‐gap magnetic field distribution is the essential prerequisite of electrical machine analysis. Because of the natural periodicity of rotary machines, Fourier analysis is a suitable choice for air‐gap field prediction. However, due to the end‐effect, periodicity is not present in linear machines and the Fourier series is not appropriate. In engineering mathematics, a rigorous method of solving partial differential equations is the separation of the variables method (SVM) which is based on the hypothesis that the field solution is in the form of the product of two functions of orthogonal directions; for example, in an axisymmetric structure, a longitudinal harmonic function (LHF) and a radial harmonic function (RHF). A particular case of these functions is trigonometric functions, which result in the Fourier series. SVM is imposed in a different manner, where RHF is approximated by the Bessel–Fourier series and consequently LHF has a (piecewise) exponential behaviour. This choice of basis functions not only serves the purpose of modelling the end‐effect but also removes the Gibbs phenomenon, that is, it precisely models discontinuities of flux density at the surface of PMs. A numerical case‐study of a slotless double‐sided linear tubular surface‐PM machine shows that the piecewise exponential approximation can attain 1% error while utilising only three harmonics, whereas the trigonometric approximation, due to the Gibbs phenomenon, slowly arrives at 20% error with 100 harmonics for approximating flux density. Results of both methods were validated using the finite element method (FEM). Additionally, it was discovered that the computational complexity of the model is independent of varying position; therefore, the analytical method could yield the back electromotive force and electromagnetic thrust force for a number of 320 positions at merely 0.2 s while the FEM software required 5 min.

AbstractA K‐band eight‐element phased‐array receiver is proposed, featuring a reconfigurable beam count and high Tx‐band rejection, tailored for satellite communication applications. By precisely designing the inter‐stage and output matching networks of the four‐stage low‐noise amplifier, the Tx‐band rejection of the receiver can be effectively enhanced to align with the requirements of more than 35 dB in shared‐aperture phased‐array applications. Meanwhile, the reconfigurable power divider is meticulously designed to achieve three different operation modes, which allows the eight‐element receiver to be configured for one, two, or four simultaneous beams. In addition, an active vector‐modulated phase shifter is designed to meet the demands of precise phase shifts of phased‐array systems. Based on the proposed method, a K‐band eight‐element reconfigurable phased‐array receiver operating from 17.7 to 21.2 GHz is designed and measured. The measurement exhibits more than 35‐dB Tx‐band rejection, 21–24.5 dB for single‐channel gain, and lower than 2.6 dB for noise figure within the design bandwidth. Meanwhile, the measured root mean square (RMS) gain error and RMS phase error are confined within 0.8 dB and 3.7°, respectively.

AbstractA strict correlation among proximal tubule epithelial cell dysfunction,
proteinuria, and modulation of the Renin-Angiotensin System and Kalikrein-Kinin
System are crucial factors in the pathogenesis of Acute Kidney Injury (AKI). In
this study, we investigated the potential protective effect of preconditioning
by moderate-intensity aerobic exercise on gentamicin-induced AKI. Male Wistar
rats were submitted to a moderate-intensity treadmill exercise protocol for 8
weeks, and then injected with 80 mg/kg/day s.c. gentamicin for 5 consecutive
days. Four groups were generated: 1) NT+SAL (control); 2) NT+AKI (non-trained
with AKI); 3) T+SAL (trained); and 4) T+AKI (trained with AKI). The NT+AKI group
presented: 1) impairment in glomerular function parameters; 2) increased
fractional excretion of Na + , K + , and water; 4)
proteinuria and increased urinary γ-glutamyl transferase activity (a marker of
tubular injury) accompanied by acute tubular necrosis; 5) an increased renal
angiotensin-converting enzyme and bradykinin B1 receptor mRNA expression.
Interestingly, the preconditioning by moderate-intensity aerobic exercise
attenuated all alterations observed in gentamicin-induced AKI (T+AKI group).
Taken together, our results show that the preconditioning by moderate-intensity
aerobic exercise ameliorates the development of gentamicin-induced AKI. Our
findings help to expand the current knowledge regarding the effect of physical
exercise on kidneys during physiological and pathological conditions.
Redução fechada assistida por Schanz (SACR): Uma nova técnica de redução para fixação intramedular elástica estável de fraturas pediátricas do antebraço
Authors: Masquijo Julio Javier 
Published: July 2024

ResumoFraturas dos dois ossos do antebraço são prevalentes entre pacientes pediátricos. A haste intramedular elástica estável (ESIN, na sigla em inglês) é uma excelente opção para fraturas do antebraço que requerem estabilização cirúrgica em crianças e adolescentes. A redução fechada de fraturas do terço proximal pode ser particularmente difícil, e as múltiplas tentativas malsucedidas de inserção da haste podem aumentar o risco de síndrome compartimental. Este artigo apresenta uma nova técnica chamada redução fechada assistida por Schanz (SACR, na sigla em inglês) com uso de um Shanz de 4 mm para facilitar o alinhamento e a inserção da haste e evitar as complicações associadas a tempos operatórios mais longos e à redução aberta.
Lung Transplant for Chronic Obstructive Pulmonary Disease
Authors: Swartz Kyle , Mansour Ali , Alsunaid Sammar 
Published: July 2024

AbstractChronic obstructive pulmonary disease (COPD) carries a high burden of morbidity and mortality to patient and a high cost to health care systems. Lung transplantation is a last resort available for end-stage COPD patients interested in pursuing it and meeting the strict transplant requirements. It requires commitment from patients and their loved ones to support them through this tough process. This review will cover history of transplant, indications, candidate selection, evaluation testing, transplant listing, type of transplant (single versus bilateral), posttransplant complications, immunosuppression, and rejection. It is tailored to the COPD patient when applicable; however, many aspects of lung transplantation are shared amongst all lung diseases eligible for transplant.
Chart Review and Practical Recommendations for the Use of Methadone as an Alternative to Opioid Rotation in the Management of Cancer-Related Pain

Published: July 2024

Abstract
Introduction Palliative care, with a focus on enhancing the quality of life for individuals facing life-limiting illnesses, relies on effective pain management as a fundamental component. Opioids, particularly methadone, play a crucial role in addressing moderate to severe pain in palliative care due to their unique pharmacological properties. Methadone, a long-acting opioid agonist and N-methyl-D-aspartate receptor antagonist, is valuable for treating both nociceptive and neuropathic pain. However, the transition to methadone from other opioids requires careful consideration.
Objectives This study examines the use of methadone as an alternative to morphine or fentanyl for managing refractory cancer pain in a tertiary care hospital in India.
Methods We conducted a retrospective analysis of anonymized medical records of cancer patients initiated on oral methadone for pain management at a tertiary cancer center's palliative medicine outpatient clinic from February 2020 to June 2021. Data included demographic characteristics, pain descriptions, concurrent analgesic use, reasons for transitioning to methadone, rotation methods, methadone dosages, clinical outcomes, adverse effects, and treatment discontinuations. Patients were routinely followed up, with pain scores, morphine equivalent daily doses, and methadone requirements recorded at each visit.
Results Forty-four patients received methadone, either as a coanalgesic (41/44) or primary opioid (3/44). Refractory cancer pain, with a neuropathic component, was the predominant indication for methadone use. Following the methadone initiation, all patients experienced significant pain relief. Median daily methadone dose increased from 5 to 7.5 mg after 1 week. Adverse effects were minimal, with one patient experiencing QTc interval prolongation. Patient-specific factors often necessitated deviations from equianalgesic conversion tables in determining methadone dosages.
Conclusion Methadone offers a viable option for refractory cancer pain when conventional treatments fall short. Physicians should prioritize personalized titration and thorough assessment during opioid rotation, rather than relying solely on conversion tables. Further research is needed to explore alternative approaches for opioid rotation and to expand our understanding of methadone's optimal use in cancer pain management.
Family firms and the governance of global value chains

Published: July 2024

AbstractThe current evolution of global value chains (GVCs) calls for moving beyond the “unipolar” view of lead multinational enterprises (MNEs) as sole rulers to examine how their characteristics and those of partner firms affect GVC governance. In response to this call, we focus on family firms, which are the most ubiquitous organizational form worldwide and represent the majority of firms participating in GVCs. Unlike non-family firms, these organizations face distinct mixed gambles, driven by both economic and non-economic goals. However, internalization theory and the associated global factory model, which explain GVC governance, rely solely on economic assessments, limiting our understanding and predictability of MNE behavior. Therefore, in this study, we show how location decisions, degree of internalization, and relationship management in GVCs differ from the conventional global factory model when family firms are involved as lead MNEs and/or partners. By analyzing how comparative efficiency considerations change when family firms are involved, we offer implications for internalization theory and provide a more comprehensive framework for understanding control and trust dynamics in GVCs. Thus, we pave the way for future research to revise and enrich international business theories, taking into account the distinctiveness and heterogeneity of family firms.
Determination of the dynamic Young’s modulus of quantum materials in piezoactuator-driven uniaxial pressure cells using a low-frequency AC method

Published: July 2024

We report on a new technique for measuring the dynamic Young’s modulus, E, of quantum materials at low temperatures as a function of static tuning strain, ϵ, in piezoactuator-driven pressure cells. In addition to a static tuning of stress and strain, we apply a small-amplitude, finite-frequency AC (1 Hz ≲ ω ≲ 1000 Hz) uniaxial stress, σac, to the sample and measure the resulting AC strain, ϵac, using a capacitive sensor to obtain the associated modulus E. We demonstrate the performance of the new technique through proof-of-principle experiments on the unconventional superconductor Sr2RuO4, which is known for its rich temperature–strain phase diagram. In particular, we show that the magnitude of E, measured using this AC technique at low frequencies, exhibits a pronounced nonlinear elasticity, which is in very good agreement with previous Young’s modulus measurements on Sr2RuO4 under [1 0 0] strain using a DC method [Noad et al., Science 382, 447–450 (2023)]. By combining the new AC Young’s modulus measurements with AC elastocaloric measurements in a single measurement, we demonstrate that these AC techniques are powerful in detecting small anomalies in the elastic properties of quantum materials. Finally, using the case of Sr2RuO4 as an example, we demonstrate how the imaginary component of the modulus can provide additional information about the nature of ordered phases.
Significant promotion of NO separation selectivity from flue gas by the –NH2 functional group on Fe–Ni bimetallic MOF at ambient conditions
Authors: Li Hao , Zhang Han , Yue Xinyu , Ban Jingshu , Hu Jie , Tang Fushun 
Published: July 2024

In this paper, the bimetallic metal–organic frameworks (MOFs) of FeNi-BDC and FeNi-BDC-NH2 (BDC, 1,4-benzenedicarboxylate) with similar Fe/Ni molar ratio, crystal structure, porosity and thermal stability were synthesized by a solvothermal method. The results of adsorption experiments at ambient conditions showed that the adsorptive uptake of NO, CO2, O2 and N2 on FeNi-BDC were all very small under different adsorption partial pressures, with FeNi-BDC displaying a weak adsorption property because of its lack of unsaturated adsorption sites. On the contrary, at 100 kPa, the adsorption of NO by FeNi-BDC-NH2 was considerably higher than that by FeNi-BDC, indicating that the incorporation of NH2 on the ligand could effectively enhance the adsorption of NO. The adsorption capacity of FeNi-BDC-NH2 for NO reached 142.17 cm3 g−1, which was considerably higher than its capacity for CO2, O2 and N2 under the same conditions. Ideal Adsorption Solution Theory simulations calculated the adsorption selectivity for NO/CO2 and NO/O2 under a mixed atmosphere to reach 1325 and 13,346 respectively, demonstrating high adsorption selectivity. Through in situ infrared experiments and calculations of the enthalpy of adsorption, it was demonstrated that FeNi-BDC-NH2 adsorbed NO because NO can combine with NH2 in the material to form a NONOate structure. A preliminarily exploration of the mechanism of NO adsorption and the influence of NH2 functional groups on the adsorption and separation of NO revealed that the selectivity of adsorption was closely related to the variability of the enthalpy of adsorption. This also provided a new strategy for the adsorption and separation of NO in the flue gas environment.
Cultural ergonomics in localization
Authors: Tsai Nancy 
Published: July 2024

Abstract
Cultural ergonomics aims to integrate the dimension of culture into systems and products to make them safer, more
useful, and more accessible to a wider range of multicultural users. This makes it an effective conceptual tool to create a
localized product that is more inclusive. By using the example of security questions in drop-down menus replicated across North
American English websites, this paper argues that overlooking ‘culture’ as a site of diverse experiences leads to a
harder-to-navigate product for the multicultural user. By juxtaposing the reality of a multicultural context with the monoethnic,
middle-class, and heteronormative cultural dimensions of security questions, the cloning of questions across websites can be seen
as satisfying the needs of the dominant power rather than the subordinated peoples – both immigrant and non-heteronormative.
Operationalizing cultural ergonomics in the translation workflow provides a means to recognize and address this power
imbalance.
Evaluation as a persuasive tactic in the 2012 Obama-Romney
debates
Authors: Halmari Helena 
Published: July 2024

Abstract
The focus of this article is the deictic evaluative
construction that’s, as used by Barack Obama and Mitt
Romney during the 2012 presidential debates. A summative clause, often
toward the end of a discourse turn, opened by the distal demonstrative
pronoun that, has a persuasive function, evaluating the
immediately preceding discourse content. This construction allows the
speaker to evaluate his own message positively and the opponent’s message
negatively; it also structures the content clearly and concisely, helping to
portray the speaker as one with a strong and clear agenda. A quantitative
comparison of the usage of the that’s construction with
regard to Obama and Romney shows that both used it equally during the first
debate; however, in the second debate, Obama doubled its use. This chapter
brings together a concept from narrative theory (evaluation) and a concept
from rhetoric (the persuasive function of language), as these two concepts
intersect within the persuasive genre of presidential debates.
The uses of laughter in epideictic radio interviews
Authors: Myers Greg 
Published: July 2024

Abstract
A number of researchers have dealt with laughter as a
strategic device in broadcast interviews and press conferences. I consider
how laughter works in a genre in which part of the purpose is to praise the
interviewee – what I call epideictic interviews. These interviews have
interactional problems around presenting and accepting praise. Laughter can
be placed so that it acknowledges and mitigates these problems. Typically,
interviewee laughter comes in response to interviewer praise, or in the
performance of humorous material. Interviewer laughter often marks for the
audience that material is to be taken as non-serious. Analysis of laughter
tells us both about the peculiarities of interaction in this broadcast
genre, and about the difficulties in performing and listening to praise.
Revisiting adaptability
Authors: Vásquez Camilla , Cenni Irene 
Published: July 2024

Abstract
Recognized for their influence on consumer
decision-making, online consumer reviews have attracted the attention of
scholars from marketing, consumer studies and tourism, as well as discourse
studies. Taking Virtanen’s (2017)
study of Amazon book reviews as our point of departure, this study builds on
prior linguistic work describing the discourse focus of online reviews. We
examine reviews of a virtual tourism product, Airbnb’s Online Experiences
(AOE). Applying Virtanen’s tri-partite framework (Topic, Author, Audience)
to a set of 200 AOE reviews, this study explores how review writers frame
their evaluative comments. Building on this framework for analyzing the
discourse structure and discourse focus of online reviews, our findings
identify different patterns of adaptability in response to the communicative
demands of this novel reviewing context.
Vernacular voices in the public sphere
Authors: Gill Martin 
Published: July 2024

Abstract
Though criticized for attracting bigots and haters,
‘below the line’ (BTL) comment spaces extend the public sphere to include
vernacular voices that rarely figure in mainstream democratic debate. This
study examines interaction among commenters in a corpus of comments posted
to the British newspaper the Express on the divisive issue
of Britain’s withdrawal from the European Union. It shows how in this
context regular BTL commenters create and perform an authentic ‘Brexiter’
identity in opposition to public norms of civility, through displays of
in-group solidarity and collective out-group hostility. It further shows how
this aggressive behaviour is deliberately orchestrated and channelled by the
newspaper itself. The study suggests that, as a result, the common ground
essential to democratic participation is not being extended but eroded, to
the detriment of all.
Variation in psychopathological terminology
Authors: Vezzani Federica , Costa Rute 
Published: July 2024

Abstract
Representing specialized knowledge in the medical domain implies considering the dynamism of scientific and
technological progress. The advancement of knowledge on diseases goes hand in hand with the reconceptualization processes
undertaken by experts with consequent conceptual evolutions and possible variations of the terms used to designate medical
concepts. Sometimes term variation is the result of a desire to avoid or overcome negative connotations anchored in medical terms,
and leads to the creation of less evaluatively charged terms that carry a diminished ideological load.
This study illustrates the case of Body Dysmorphic Disorder (BDD), a relatively under-/misdiagnosed medical
condition which has been the object of multiple reconceptualizations by experts. We focus on the analysis of the conceptual
evolution of BDD and the consequent variation occurring at the linguistic level. We adopt the theoretical assumption that
terminology has a double dimension – conceptual and linguistic. Following on this assumption, the terminologist must examine both
the experts’ conceptualizations of a given domain and the discourses produced by them in order to effectively represent the
specialized knowledge of a specific subject field. To complete the analysis, we present how information about BDD is disseminated
to non-experts through the analysis of a corpus of mass-media articles.
Metaphors for legal terms concerning vulnerable people
Authors: Mannoni Michele , Cavalieri Silvia 
Published: July 2024

Abstract
This study takes a cognitive view of metaphor to investigate the terms designating vulnerable people used in two
legal languages, namely English as used in the European Union and Mandarin Chinese. We applied a discourse dynamics approach to
metaphor to explore the implicit connotations of the terms identifying different groups of vulnerable people (e.g., minors,
disabled people, victims of human trafficking). The findings show that even when appearing in legal texts, many of the key terms
for these groups are not objective, nor are they unbiased and detached from our subjective and bodily experience of the world.
When these terms are connoted, they tend to have negative connotations, raising concerns about their social implications. This
study highlights the entailments of embodiment theories for terminology and proposes that the identification of groups of
vulnerable people is a social product motivated by unconscious relations of power rather than relations of assistance and
reciprocity.
