Optimization of transmission lines congestion management in integrated electricity and natural gas multi‐carrier energy systems
Authors: Khoshbouy Morteza , Kazemzadeh Rasool 
Published: January 2024

AbstractThe increasing interactivity between energy carrier networks such as electrical, natural gas (NG), and heating can be appropriately used for improving the operation optimality along with overcoming some challenges of those systems. With such a view, this paper studies the practical issue of power transmission lines congestion management in integrated multicarrier energy systems (MCESs) and makes a comparison with the only electrical operation mode. The MCES consisting of electrical and NG network infrastructures with exchanged energy between them is modelled by considering the several local energy hubs and their electrical and heat loads. Rescheduling of energy sources (power plants and gas wells) and demand side management in both electrical and NG networks have been utilized as the two important tools in the developed congestion alleviation framework. The proposed method confirms that the provided flexibility in the integrated operation of the MCESs can lead to a remarkable reduction in the congestion management cost index. Implementing the proposed congestion management framework on an assumed test MCES with a combined 39‐bus New England power system and 20‐node Belgium NG system demonstrates its effectiveness and applicability for the system operators.
SOC estimation and fault identification strategy of energy storage battery PACK: Based on adaptive sliding mode observer
Authors: Xueyi Huang , Tinglong Pan 
Published: January 2024

AbstractAccurate state of charge (SOC) estimation and fault identification and localization are crucial in the field of battery system management. This article proposes an innovative method based on sliding mode observation theory for SOC estimation and short‐circuit fault location. The core of this new method is the design of an adaptive sliding mode observer, which reduces jitter by introducing adaptive switching gain, establishes an internal loop of gain and error, and improves the performance of SOC estimation. In addition, recursive least squares method was used to identify the key parameters of the model. Secondly, based on obtaining the SOC of each battery cell in series with the energy storage PACK, the specificity of the faulty battery cell in SOC change trend is utilized to identify and locate the short‐circuit fault of the energy storage PACK. The simulation and test results show that the designed adaptive sliding mode observer can significantly improve the estimation accuracy of SOC and has better stability. Compared to the commonly used Kalman estimation and BP neural network estimation methods, the designed method has improved accuracy by 5.53% and 3.42%, respectively. In addition, based on the accurate identification of SOC, the short‐circuit fault diagnosis results of the battery PACK have a high accuracy, confirming the feasibility and effectiveness of the designed strategy that includes SOC estimation and short‐circuit fault identification and positioning, and has broad application prospects.

Published: January 2024

Aims. Our goal is to accurately determine bound-to-bound transition wavelengths and energy levels of the low-lying open-shell configurations 4f4, 4f3 5d, 4f36s, and 4f3 6p of doubly ionised neodymium (Nd III) through high-resolution spectroscopy and semi-empirical calculations.
Methods. The emission spectra of neodymium (Nd, Z = 60) were recorded using Penning and hollow cathode discharge lamps in the region 11 500-54000 cm−1 (8695–1852 Å) by Fourier transform spectroscopy at resolving powers up to 106. Wavenumber measurements were accurate to a few 10−3 cm−1. Grating spectroscopy of Nd vacuum sliding sparks and stellar spectra were used to aid line and energy level identification. For the analysis, new Nd III atomic structure and transition probability calculations were carried out using the Cowan code parameterised by newly established levels.
Results. The classification of 432 transitions of Nd III from the Penning lamp spectra resulted in the determination of 144 energy levels of the 4f4, 4f3 5d, 4f3 6s, and 4f3 6p configurations of Nd III, 105 of which were experimentally established for the first time. Of the 40 previously published Nd III levels, one was revised and 39 were confirmed.
Conclusions. The results will not only benchmark and improve future semi-empirical atomic structure calculations of Nd III, but also enable more reliable astrophysical applications of Nd III, such as abundance analyses of kilonovae and chemically peculiar stars, and studies of pulsational wave propagation in these stars.

Published: January 2024

Abstract
Background Several musculoskeletal changes occur in pregnancy,
particularly in the abdominal region. The aim of this study was to search and
compare the effects of long (LEP) and short exercise programs (SEP) in terms of
the satisfaction of the needs of pregnant women.
Methods This study consisted of 2 groups: LEP (n=16) and SEP
(n=16). Muscle thickness measurements determined by ultrasound, the
6 minute walk test, Pregnancy Physical Activity Questionnaire, Visual
Analogue Scale, Oswestry Disability Index, and Short Form-36 Quality of Life
Questionnaire were the study variables. Evaluations were done at the 16th
(baseline), 24th, and 32nd gestational weeks. The LEP consisted of 20 and the
SEP consisted of 9 exercises, which were applied for 16 weeks until the 32nd
gestational week.
Results Emotional role limitation and pain scores of quality of life,
6 minute walk test, and occupational physical activity were found to be
better in the LEP group at the 24th gestational week (p=0.043,
p=0.049, p=0.049, p=0.026). At the 32nd gestational
week, the 6 minute walk test and occupational physical activity were
found to be higher in the LEP group (p=0.006, p=0.017).
Additionally, rectus abdominis and bilateral diaphragm muscle thicknesses,
“moderate intensity and sports physical activity” and
“vitality and emotional well-being” were increased over time
with the LEP (p+<+0.05 for all). On the other hand,
unilateral diaphragm muscle thickness, sports physical activity level, and
vitality were improved with the SEP (p+<+0.05 for
all).
Conclusions The SEP and LEP both have beneficial effects in pregnant
women. However, the LEP increases physical activity level, functional capacity,
and quality of life more than the SEP during the later stages of pregnancy.

Published: January 2024

AbstractNonosseous abnormalities are often seen on bone scans and can be related to a wide variety of pathology ranging across vascular, infection, and inflammatory etiology. Diffuse soft tissue radiotracer uptake on bone scans is typically attributed to renal or metabolic derangements. Calciphylaxis is the deposition of calcium in small blood vessels, skin, and other organs leading to vascular obstruction and skin necrosis. It is a rare disorder with unknown pathophysiology. Diagnosis of calciphylaxis is challenging and requires an interdisciplinary approach including clinical findings, laboratory results, medical imaging, and skin biopsy. An early diagnosis is important as the disease is associated with high morbidity and mortality. The purpose of this review article is to highlight the role of bone scintigraphy in the evaluation of calciphylaxis and to correlate the findings with other imaging modalities and histopathology.

The Three Powerful Traditions of Thinking that Constitute Homeopathy
Authors: Schmidt Josef M. 
Published: January 2024

AbstractBy means of a historical, classical philological and philosophical approach, this paper attempts to demonstrate that homeopathy is based on three powerful traditions of thinking, which can be traced back to Ancient Greece's pre-Socratic era. Actually, it seems to be constituted by what may be termed lógos-, hómoion- and iásthai-thinking: that is, thinking in terms of rationality, similarity and healing. By contrast, modern medicine tends to be aligned with just one of these traditions, at the expense of the others, this being not without risk and adverse effects. It is mainly determined by the first type of rationality that genealogically derives from, and is therefore compatible with, the logic of economics whose predominance in the health care systems of modern societies is progressively rising. Homeopathy, however, may not be sufficiently and fairly understood without taking into account the complementary forms of thinking on which it also rests, such as the principle of similarity in an all-encompassing sense, and ancient healing knowledge in the tradition of catharsis. As a corollary of being essentially constituted by the three, homeopathy may persistently be in need of a dynamic equilibrium of its three constituent bases. Attempts to approach homeopathy from only one of the indicated modes of thinking fail to grasp its essence and result in figments or caricatures of what homeopathy was originally meant to be.

Published: January 2024

AbstractFetoscopic laser coagulation is offered as a method of treatment for twin-to-twin transfusion syndrome or twin anemia polycythemia sequence. It involves laser ablation of intercommunicating superficial blood vessels on the surface of the placenta, under sono-endoscopic control. Preterm labor and preterm prelabor rupture of the membranes are known complications. The results depend on the expertise of the surgeon, location of the placenta, indication for treatment, severity of disease, and growth of babies. The chances of both babies surviving are around 65% and one baby surviving is 85%.
Self-reported attention and hyperactivity symptoms among adults with epilepsy
Authors: Bergamaschi Eduardo de Novaes Costa , Machado Gabriela , Rodrigues Gabriel Martins , Lin Katia 
Published: January 2024

Abstract
Background Patients with epilepsy (PWE) frequently have comorbid psychiatric disorders, the most common of which are depression and anxiety. Attention deficit disorder with hyperactivity (ADHD) is also more frequent among PWE, though that condition has been scarcely studied among the adult PWE population.
Objective This study aimed to compare the presence of ADHD symptoms between adult PWE and the general population.
Methods This was an observational case-control study. Ninety-five adult PWE from a tertiary center in southern Brazil were compared with 100 healthy controls. All subjects were submitted to three structured scales: 1) the World Health Organization Adult ADHD Self-Report Scale version 1.1 (ASRS); 2) the Hospital Anxiety and Depression Scale (HADS); and 3) the Adverse Events Profile (AEP). Dichotomic variables were analyzed through chi-square test and Fisher's exact test, as appropriate, and non-parametric variables were analyzed through the Mann-Whitney U test.
Results Medians and interquartile ranges (IR) were: 1) ASRS: 26.00 (IR: 18 to 38) among PWE versus 17.00 (IR: 11 to 24) among controls, p < 0.001; 2) HADS: 14.00 (IR: 8 to 21) among PWE versus 11.00 (IR: 8 to 16) among controls, p = 0.007; 3) AEP: 3800 (IR: 31 to 49) among PWE versus 33.00 (IR: 23 to 43) among controls, p = 0.001.
Conclusion PWE showed a higher burden of symptoms of ADHD, depression, and anxiety when compared with controls, which replicates in the Brazilian population the findings of current literature that point toward a higher prevalence of such disorders among PWE.
‘A Grand Strategic Error’: the British military elite’s role in the invasion of Iraq
Authors: Dixon Paul 
Published: January 2024

AbstractPresident George W. Bush required only symbolic British participation in the invasion of Iraq, so why did the Labour government deploy their maximum military effort when this was unnecessary and considerably increased the political risk to Prime Minister Tony Blair?The Chilcot Report(2016) provides considerable evidence of the military elite’s role, in pursuit of their perceived organisational interests, not only lobbying but also manipulating the Labour government into a maximum military role. Shortly after the invasion, the military elite began to pursue their next war, again pressuring and manipulating the government into Britain’s deployment to Helmand, Afghanistan, in 2006. While fighting wars in both Iraq and Afghanistan, the military elite were overstretched and in crisis, yet they successfully empowered themselves by deflecting responsibility onto the Labour government. Consequently, it is argued that the lack of democratic control over the military makes Britain particularly disposed to belligerence and fighting further unnecessary wars.
Trade liberalization, city size, and urban wage premium: evidence from China’s city and individual micro-data
Authors: Zhang Wenwu , Wang Jiayin , Ou Xi 
Published: January 2024

AbstractIn the context of trade liberalization and new urbanization, it is important to study how urban openness leads to wage premiums and improvements in income distribution. This paper utilizes micro-data from the Chinese Household Income Project and matching data from 144 cities to investigate the relationship between trade liberalization, urban scale, and urban wage premiums. The results indicate that trade liberalization significantly increases urban wage premiums, which is particularly evident during the early stages of China’s accession to the WTO. However, this effect may fluctuate over time. Surprisingly, in China, the urban scale can increase labor wage income, but it does not magnify the wage premium effect of trade liberalization. Heterogeneity tests based on regions, firms, and income groups suggest that the wage premium effect of trade liberalization is higher in eastern and central region cities than in western region cities, labor wage growth in the service sector is more pronounced than in the industrial sector, and the impact of trade liberalization on wage growth for the middle and lower-income groups is greater than for the high-income group, which helps to narrow income disparities among different groups. These findings are of great policy significance for improving income distribution through labor market liberalization. In this context, they highlight the importance of comprehensive openness and new urbanization in China.
Origin of primeval seed magnetism in rotating astrophysical bodies
Authors: Hossain Golam Mortuza , Mandal Susobhan 
Published: January 2024

Abstract
We show that a primeval seed magnetic field arises due to spin-degeneracy
breaking of fermions caused by the dragging of inertial frames in the curved
spacetime of rotating astrophysical bodies. This seed magnetic field would arise
even due to electrically neutral fermions such as neutrons. As examples, firstly
we show that an ideal neutron star rotating at 500 revolutions per second,
having mass 0.83 M⊙ and described by an ensemble of degenerate
neutrons, would have 0.12 Gauss seed magnetic field at its center arising
through the breaking of spin-degeneracy. Secondly, similar seed field at a
proto-galactic stage for the Milky Way galaxy as implied by its observed
rotation curve is estimated to be between 10-19–10-24 Gauss, a field
strength which is known to be sufficient to produce presently observed
microgauss magnetic field.

Published: January 2024

Abstract
The UIO-66 studied in this paper exhibits unprecedented thermal stability with a very high surface area and mechanical strength. This unique combination of properties opens up a wide range of promising applications. Here, we investigate the saturable absorption effects and ultrafast photonic applications of UIO-66. It shows that UIO-66 could emerge as a novel nonlinear material for ultrafast optics. By fabricating a real saturable absorber and incorporating it into a passively mode-locked Er-doped fiber laser, traditional solitons with a pulse duration of 0.96 ps at a repetition rate of 4.12 MHz have been obtained. The mode-locked spectrum centered at 1562.4 nm features a full width at half maximum of 3.5 nm. Our results may trigger follow-up investigations on the optical properties of UIO-66 and pave potential avenues for photonic and optoelectronic applications.

Abstract

Objective. Current retinal prosthetics are limited in their ability to precisely control firing patterns of functionally distinct retinal ganglion cell (RGC) types. The aim of this study was to characterise RGC responses to continuous, kilohertz-frequency-varying stimulation to assess its utility in controlling RGC activity. Approach. We used in vitro patch-clamp experiments to assess electrically-evoked ON and OFF RGC responses to frequency-varying pulse train sequences. In each sequence, the stimulation amplitude was kept constant while the stimulation frequency (0.5–10 kHz) was changed every 40 ms, in either a linearly increasing, linearly decreasing or randomised manner. The stimulation amplitude across sequences was increased from 10 to 300 µA. Main results. We found that continuous stimulation without rest periods caused complex and irreproducible stimulus-response relationships, primarily due to strong stimulus-induced response adaptation and influence of the preceding stimulus frequency on the response to a subsequent stimulus. In addition, ON and OFF populations showed different sensitivities to continuous, frequency-varying pulse trains, with OFF cells generally exhibiting more dependency on frequency changes within a sequence. Finally, the ability to maintain spiking behaviour to continuous stimulation in RGCs significantly reduced over longer stimulation durations irrespective of the frequency order. Significance. This study represents an important step in advancing and understanding the utility of continuous frequency modulation in controlling functionally distinct RGCs. Our results indicate that continuous, kHz-frequency-varying stimulation sequences provide very limited control of RGC firing patterns due to inter-dependency between adjacent frequencies and generally, different RGC types do not display different frequency preferences under such stimulation conditions. For future stimulation strategies using kHz frequencies, careful consideration must be given to design appropriate pauses in stimulation, stimulation frequency order and the length of continuous stimulation duration.

The hfrh-buck (high frequency radiation hardened-buck) is a radiation hardened DC/DC-converter operating at a high switching frequency of 100 MHz with a small air core inductor of 22 nH. To ensure a high radiation dose, the circuit is designed with core transistors of a 65 nm TSMC technology. By stacking the transistors of the power stage, the converter can be supplied with a voltage of up to 4.8 V. Stable operation can be achieved at an output voltage of 1.2 V with a maximum load current of 1 A. The prototype demonstrates the ability to power parallel connected hybrid-pixel modules in the innermost layers.
Magnetic resilience studies for power supplies

Published: January 2024

Abstract
It is well understood that modern physics experiments often require more Low Voltage
power to be delivered to front-end electronics than was needed in past, and that the most
effective and efficient means of delivering this LV power requires that the power supplies be
placed as close as possible to the detector. Unfortunately, this means that the LV power supplies
must be more robust and tolerant to radiation and magnetic fields typically present in such an
environment.

Designing a power supply capable of operating in such an environment is not a trivial task. It is first necessary to fully assess and understand these special conditions before one can begin to identify the power supply typology and components to be used. In this manuscript we will illustrate the design process of the CAEN EASY BRIC1 (B & Rad tolerant Intermediate Converter), an intermediate converter utilized to power the front-end electronics (12 V to 300 V) of the ATLAS-NSW experiment. The complete process is described, from design choice, to component selection, to circuit testing from B=0 to 1 T, and finally deployment and testing the complete power supply in an operational environment.

Published: January 2024

Abstract
Clinically, tumor removal surgery leaves irregularly shaped wounds that are susceptible to bacterial infection and further lead to excessive inflammation. Injectable hydrogel dressings with antimicrobial and anti-inflammatory properties have been recognized as an effective strategy to care for postoperative tumor wounds and prevent recurrence in recent years. In this work, we constructed a hydrogel network by ionic bonding interactions between quaternized chitosan (QCS) and epigallocatechin gallate (EGCG)-Zn complexes which were coordinated by EGCG and zinc ions. Because of the synergistic effect of QCS and EGCG-Zn, the hydrogel exhibited outstanding antimicrobial capacity (>99.9% inhibition), which could prevent infections caused by Escherichia coli and Staphylococcus aureus. In addition, the hydrogel was able to inhibit the growth of mice breast cancer cells (56.81% survival rate within 72 h) and reduce inflammation, which was attributed to the sustained release of EGCG. The results showed that the hydrogel was effective in inhibiting tumor recurrence and accelerating wound closure when applied to the postoperative tumor wounds. This study provided a simple and reliable strategy for postoperative tumor wound care using antimicrobial and anti-inflammatory injectable dressings, confirming their great potential in the field of postoperative wound dressings.
