Published: October 2024

AbstractThe increasing penetration of power‐electronics interfaced resources brings new challenges regarding the small‐signal stability of power systems. To address this issue, grid‐forming (GFM) controlled converters have emerged as an alternative to their conventional grid‐following counterparts. This paper investigates the mechanisms behind converters driven stability and quantifies the stabilizing effect of GFM controls. The linearized state‐space model of different combinations of control strategies is analysed in a multi‐infeed system considering various operating points. Through a parametric sensitivity study and an examination of the participation factors of key eigenvalues of the linearized models, it is confirmed that GFM controls contribute to system stabilization. Moreover, this paper demonstrates that this stabilizing effect varies significantly depending on the specific GFM control implemented: whether a current control loop is used or not notably impacts stability.
Fault location method for new distribution networks based on waveform matching of time–frequency travelling waves
Authors: Zhou Zhongqiang , Wen Yuan , Deng Moujun , Ma Jianwei , Zeng Jupeng , She Xiaolong 
Published: October 2024

AbstractSome existing fault location methods for distribution networks rely too much on the local wave head information of the time or frequency domain signals, making it difficult to adapt to the increasingly complex structure and operating conditions of the distribution network after the new energy access. For improvement, the travelling wave (TW) time and frequency ranges that can effectively avoid waveform distortion caused by new energy access are analysed. The one‐to‐one matching relationship between the TW waveforms in these ranges and the fault positions is revealed. A fault TW time–frequency matrix with specific time and frequency windows is constructed, and a new distribution network fault location method is proposed based on the matching technique of waveform features, which realises the accurate fault location by exploring the proportionality between the cumulative trend of the matrix energy amplitude deviation and the fault point position. Simulation test results show that the proposed method is not affected by the complex structure of distribution networks such as new energy access and overhead‐cable line mixing on fault location and flexibly transforms the fault location problem into a time–frequency TW waveform matching problem, which improves the accuracy and robustness of the fault location for new distribution networks to a degree.

Published: September 2024

ZusammenfassungIn der Kieferorthopädie ist eine präzise und akkurate Diagnostik notwendig, um
die Ursachen von dentalen und skelettalen Malokklusionen zu analysieren und
patientenindividuelle Therapiekonzepte zu entwickeln. Auf dieser Basis kann
entschieden werden, ob eine Dysgnathie ursächlich therapiert, oder ob eine
dentoalveoläre Kompensation angestrebt werden soll. Für den Erfolg der Therapie
ist dann die Wahl einer geeigneten Verankerung maßgeblich.Die skelettale Verankerung stellt in vielen Situationen eine nebenwirkungsarme
und effektive Alternative zu konventionellen Verankerungsmöglichkeiten dar. In
einigen Fällen erlaubt sie zudem Maßnahmen, die anders gegenwärtig nicht
umgesetzt werden können. Ein relevanter Unterschied kieferorthopädischer
Implantate im Vergleich zu dentalen Implantaten ist dabei, dass sie nur temporär
im Knochen verbleiben, sodass sich die mikro- und makrostrukturellen
Anforderungsprofile unterscheiden.Ziel des Artikels ist es, die Geschichte der skelettalen Verankerung in der
Kieferorthopädie zusammenzufassen, Charakteristika kieferorthopädischer
Mini-Implantate aufzuzeigen, die wichtigsten Insertionsgebiete zu beleuchten und
typische Indikationen zu erläutern.
From Standard of Care to Emerging Innovations: Navigating the Evolution of Pharmacological Treatment of Gestational Diabetes

Published: September 2024

The incidence of gestational diabetes mellitus (GDM) continues to increase in the United States and globally. While the first-line treatment of GDM remains diet and exercise, 30% of patients with GDM will require pharmacotherapy. However, many controversies remain over the specific glycemic threshold values at which pharmacotherapy should be started, how intensified the therapy should be, and whether oral agents are effective in GDM and remain safe for long-term offspring health. This review will summarize recently completed and ongoing trials focused on GDM pharmacotherapy, including those examining different glycemic thresholds to initiate therapy and treatment intensity.

Published: September 2024

AbstractGlucagon-like peptide-1 (GLP-1) receptor agonists are effective hypoglycemic
agents for type 2 diabetes mellitus (T2DM). It was reported that T2DM was
implicated in pancreatic β-cell senescence. Whether loxenatide regulates
cellular senescence of pancreatic β-cells is to be investigated. Our results
revealed that high glucose (HG)-induced cellular senescence and elevated
expression of SASP factors inhibited cell proliferation and stimulated DNA
damage, which were reversed by loxenatide treatment. In addition, HG induction
resulted in promoted insulin secretion and insulin synthesis of pancreatic
β-cells and loxenatide treatment further strengthened these influences. In
addition, loxenatide could inactivate the PERK/eIF2α signaling pathway via
decreasing the levels of p-PERK and p-eIF2α in HG-induced pancreatic β-cells.
Furthermore, CCT020312, an activator of the PERK/eIF2α signaling pathway,
abolished loxenatide-mediated inhibiting cellular senescence, elevating cell
proliferation and improving DNA damage and enhancing insulin secretion of
HG-induced pancreatic β-cells. In conclusion, our results indicated that
loxenatide impeded cellular senescence, promoted cell proliferation, improved
DNA damage, enhanced insulin secretion and insulin synthesis of HG-induced
pancreatic β-cells through modulating the PERK/eIF2α signaling pathway.
Epidemiology of Patient Record Duplication

Published: September 2024

Abstract
Objectives Duplicate patient records can increase costs and medical errors. We assessed the association between demographic factors, comorbidities, health care usage, and duplicate electronic health records.
Methods We analyzed the association between duplicate patient records and multiple demographic variables (race, Hispanic ethnicity, sex, and age) as well as the Charlson Comorbidity Index (CCI), number of diagnoses, and number of health care encounters. The study population included 3,018,413 patients seen at a large urban academic medical center with at least one recorded diagnosis. Duplication of patient medical records was determined by using a previously validated enterprise Master Person Index.
Results Unknown or missing demographic data, Black race when compared with White race (odds ratio [OR]: 1.35, p < 0.001), Hispanic compared with non-Hispanic ethnicity (OR: 1.48, p < 0.001), older age (OR: 1.01, p < 0.001), and “Other” sex compared with female sex (OR: 4.71, p < 0.001) were associated with higher odds of having a duplicate record. Comorbidities (CCI, OR: 1.10, p < 0.001) and more encounters with the health care system (OR: 1.01, p < 0.001) were also associated with higher odds of having a duplicate record. In contrast, male sex compared with female sex was associated with lower odds of having a duplicate record (OR: 0.88, p < 0.001).
Conclusion The odds of duplications in medical records were higher in Black, Hispanic, older, nonmale patients with more health care encounters, more comorbidities, and unknown demographic data. Understanding the epidemiology of duplicate records can help guide prevention and mitigation efforts for high-risk populations. Duplicate records can contribute to disparities in health care outcomes for minority populations.
Dermal Regeneration Template Generated Skin Can Be Raised as A Flap: A New Dimension in Aesthetic Restoration
Authors: Sharma Alok , Sankhe Manashree 
Published: October 2024

AbstractChildhood scars can lead to hideous aesthetic and functional deformities in young adults, which can be particularly distressing when involving the face and the breast in a female. Aesthetic restoration requires replacement of the whole or a part of the scarred skin by soft, pliable, and texture-matching skin, which nearly always is in short supply. Dermal regeneration templates (DRTs) can help in skin regeneration that is almost always aesthetically superior to most flaps. Aesthetic demands at the time of final restoration may require the regenerated skin to be moved as a local flap. As regenerated skin from dermal templates is known to match the vascularity of normal native skin, raising it as a flap should follow logically. This, however, has never been attempted to the best of our knowledge after a thorough literature search. We report a case of successfully using DRT-generated skin raised as a flap for aesthetic reconstruction of a postburn scarred breast in a young female. This adds a whole new dimension to the use of DRTs and points to a new field of research in scar management and aesthetic restoration.

Published: October 2024

The assignment of the hydrogen bonded O–H stretch vibration in the proline matrix IR spectrum has sparked controversy. Employing constrained nuclear electronic orbital methods, we provide a clear assignment that the vibrational frequency drops to near 3000 cm−1 as a result of the interplay between electronic effects, nuclear quantum effects, and matrix effects.

Published: October 2024

We present a comprehensive, combined experimental and theoretical study of the core-level photoelectron and near-edge x-ray absorption fine structure (NEXAFS) spectra of 2-thiouracil, 4-thiouracil, and 2,4-dithiouracil at the oxygen 1s, nitrogen 1s, carbon 1s, and the sulfur 2s and 2p edges. X-ray photoelectron spectra were calculated using equation-of-motion coupled-cluster theory (EOM-CCSD), and NEXAFS spectra were calculated using algebraic diagrammatic construction and EOM-CCSD. For the main peaks at O and N 1s as well as the S 2s edge, we find a single photoline. The S 2p spectra show a spin–orbit splitting of 1.2 eV with an asymmetric vibrational line shape. We also resolve the correlation satellites of these photolines. For the carbon 1s photoelectrons, we observe a splitting on the eV scale, which we can unanimously attribute to specific sites. In the NEXAFS spectra, we see very isolated pre-edge features at the oxygen 1s edge; the nitrogen edge, however, is very complex, in contrast to the XPS findings. The C 1s edge NEXAFS spectrum shows site-specific splitting. The sulfur 2s and 2p spectra are dominated by two strong pre-edge transitions. The S 2p spectra show again the spin–orbit splitting of 1.2 eV.

Abstract
We read with great interest the paper by Lim et al (2018 Phys. Med. Biol.
63 035042) on bias reduction in Y-90 PET imaging. In particular, they proposed a new formulation of the tomographic reconstruction problem that enforces non-negativity in projection space as opposed to image space. We comment on the algorithm they derived from this formulation and bring some clarifications on the constraint that this algorithm respects.
Evaluation of a-NbGe films as a candidate material for superconducting nanowire single-photon detector (SNSPD) applications

Abstract
We report on the superconducting properties of amorphous NbGe thin films of thickness in the range from 50 to 10 nm, to assess and compare their characteristics for single-photon detector capabilities with respect to established materials for single-photon detector (SPD). Resistance as a function of temperature and magnetic field was measured for the calculation of the microscopic parameters relevant for single-photon detector. HRXRD along with TEM analysis confirmed that the films are of an amorphous nature. Conductance fluctuation mechanisms such as Aslamazov–Larkin and Maki–Thompson were evoked to analyze the zero field (B = 0 T) resistance data and the results are in compliance with the experimental data. Similarly, the signature of 2D superconductivity in terms of Berezinskii–Kosterlitz–Thouless transition due to the binding and unbinding of vortex and antivortex pairs was also verified for a film thickness upto 25 nm. Longitudinal resistance (Rxx
) together with Hall resistance (Rxy
) was used to evaluate the superconducting and microscopic parameters of the samples both in the superconducting and in the normal state. The evaluation of single-photon detector capability is done majorly through transport measurements and the analysis of magneto-conductance above the transition temperature, through which different scattering mechanisms of the excited quasiparticles upon the incidence of the photon and its thermalization process were analyzed. Current–voltage characteristics performed at small magnetic fields enabled us to determine the vortex dynamics and the associated quasi particle relaxation time scale. Finally, the evaluated characteristics were compared with respect to the established superconducting systems for SPDs such as NbN, MoSi, WSi, NbRe etc. The characteristic time scales such as electron–electron scattering rate (τ
e–e), electron–fluctuation rate (τ
e–fl), and electron–phonon scattering rate evaluated from the transport measurements are within the same range as reported for other systems. From the analysis, we establish that a-NbGe could be a potential candidate for superconducting nanowire single-photon detectors (SNSPDs) and also a potential candidate for the wavelength tunability of SNSPDs. Changing the crystallinity of the film can alter the T
c, as well as the superconducting energy gap.
Tomographic redshift dipole: testing the cosmological principle
Authors: da Silveira Ferreira Pedro , Marra Valerio 
Published: October 2024

Abstract
The cosmological principle posits that the universe is statistically homogeneous and
isotropic on large scales, implying all matter shares the same rest frame. This principle suggests
that velocity estimates of our motion from various sources should agree with the cosmic microwave
background (CMB) dipole's inferred velocity of 370 km/s. Yet, for over two decades, analyses of
radio galaxy and quasar catalogs have found velocities at odds with the CMB dipole, with tensions
up to 5σ. In a blind analysis of BOSS and eBOSS spectroscopic data from galaxies and
quasars across 0.2 < z < 2.2, we applied a novel dipole estimator for a tomographic approach,
robustly correcting biases and quantifying uncertainties with realistic mock catalogs. Our
findings with eBOSS data (0.6 < z < 2.2), indicating a velocity of 196+92
-79-79 km/s,
demonstrate a 2σ agreement with the CMB dipole when considering the full 3D vector
distribution and a 3-to-6σ tension with previous number count studies. This result supports
the cosmological principle, emphasizing the consistency of our motion with the CMB across vast
cosmic distances. On the other hand, the BOSS data revealed potential unmodeled systematics; the
estimator could not be minimized using the LOWZ set (0.2 < z < 0.4), and the CMASS set (0.4 < z < 0.6)
presented results that pointed towards the southern hemisphere, conflicting with the CMB dipole.
Addressing the disparities with earlier number count analyses and understanding possible
systematics in spectroscopic measurements will be essential to further validate the cosmological
principle.
Cost of resilience to climate change: migration, conflicts, and epidemics in imperial China

Published: October 2024

Abstract
A growing scholarship is focusing on the cost of social resilience to climate change in the past. Among different resilience strategies, migration could be effective for nomadic societies despite the potential consequences of conflicts and epidemics. Thus, this study utilizes historical records to statistically investigate the linkages among nomadic migrations, nomad–farmer conflicts, and epidemics under climate change and population pressure in imperial China (200 BCE–1840 CE) on the national and provincial scales. The current study will first attempt to empirically identify and analyze the cost of resilience to climate change mainly in the direction from nomadic societies to agrarian societies in historical China. In particular, we show the cost of nomadic migration passed in a chain mechanism as ‘climate change → nomadic migration → nomad–farmer conflicts → epidemics.’ Nomad–farmer conflicts were one direct effect of nomadic migration, while epidemics were an indirect one. Spatially, more provinces were affected under the direct effect than under the indirect effect. Furthermore, the first level of chain ‘nomadic migration → nomad–farmer conflicts’ covers more provinces than the second level ‘nomad–farmer conflicts → epidemics’. These empirical results remind us to identify and avoid the cost of resilience as early as possible before the cost may transmit further in a chain manner. However, the provinces outside the concentrated nomad–farmer conflicts did not demonstrate significant linkages between conflicts and epidemics, which highlights the importance of peaceful cross-civilizational and inter-societal interactions against common challenges of climate change. This study with a cross-scale perspective in geography provides a theoretical implication to improve the current understanding on climate justice and have a practical value to avoid or minimize the cost of resilience.
Continuous cooling transformation in micro-alloyed medium-carbon steel and optimization of the forging process for half-shaft production
Authors: Huang Boyuan , Sun Wanli , Zhang Chaolei , Song Renbo , Sun Jianlin , Ding Wenbin 
Published: October 2024

Abstract
Micro-alloyed medium-carbon steel is increasingly used as a cost-effective alternative to quenched and tempered steel in the production of half-shaft components. Current research emphasizes controlling the microstructure during thermomechanical processing to achieve the desired structural properties after cooling. This study investigated the effect of continuous cooling transformation on the microstructure and mechanical properties of micro-alloyed medium-carbon steel. At a cooling rate of 0.5 °C s−1, only pearlite transformation occurred. At rates between 1 °C s−1 and 8 °C s−1, both bainite and martensite transformations were observed, while only martensite formed at rates exceeding 12 °C s−1. Subsequently, a four-factor, three-level orthogonal experiment was designed based on the actual production process for half shafts. The optimal forging parameters were identified as a heating temperature of 1000 °C, a deformation temperature of 920 °C, a deformation extent of 15%, and a cooling rate of 0.5 °C s−1. The study offered solutions to enhance microstructural uniformity and effectively manage abnormal bainite and martensite formations, thereby establishing a foundation for the high-quality application of micro-alloyed medium-carbon steel in half-shaft components.
Robust generation of N-partite N-level singlet states by identical particle interferometry
Authors: Piccolini Matteo , Karczewski Marcin , Winter Andreas , Lo Franco Rosario 
Published: October 2024

Abstract
We propose an interferometric scheme for generating the totally antisymmetric state of N identical bosons with N internal levels (generalized singlet). This state is a resource for various problems with dramatic quantum advantage. The procedure uses a sequence of Fourier multi-ports, combined with coincidence measurements filtering the results. Successful preparation of the generalized singlet is confirmed when the N particles of the input state stay separate (anti-bunch) on each multiport. The scheme is robust to local lossless noise and works even with a totally mixed input state.
Bone-patellar tendon-bone, hamstring, and quadriceps tendon autografts for anterior cruciate ligament reconstruction in skeletally immature patients: a systematic review
Authors: Migliorini Filippo , Cocconi Federico , Schäfer Luise , Vaishya Raju , Kämmer Daniel , Maffulli Nicola 
Published: September 2024

Abstract

Introduction
Historically, anterior cruciate ligament (ACL) ruptures in the paediatric age group were managed conservatively with bracing, casting, activity modification, and physical therapy. However, most of these patients had to reduce their sports activities, and secondary damages to the affected knee were prevalent.

Source of data
Published scientific literature in Embase, Web of Science, PubMed, and Google Scholar databases.

Areas of agreement
ACL reconstruction in children with open physes patients is debated. Any damage to the physes around the knee could lead to growth abnormalities and axial deviation of the knee.

Areas of controversy
Different grafts are available and suitable for ACL reconstruction in skeletally immature patients; however, which graft performs better remains unclear.

Growing points
This systematic review compared bone-patellar tendon-bone (BPTB), hamstring tendon (HT), and quadriceps tendon (QT) autografts for ACL reconstruction in skeletally immature patients. The joint laxity, Patient-reported outcome measures (PROMs), return to sport, and complications were compared.

Areas timely for developing research
In skeletally immature patients, HT, BPTB, and QT autografts for ACL reconstruction yielded good outcomes. Comparative studies are strongly required to establish the most suitable autograft.
