Authors: Ma Kaixue , Lin Songhua , Wu Yi 
Published: January 2024

AbstractThis paper proposes a technique named self‐packaged metal integrated suspended line (MISL) to design a high Q factor bandpass filter (BPF). This unique construction simplifies the traditional suspended stripline and substrate integrated suspended line configuration and creates a loss‐reduced structure, allowing for the implementation of high Q‐factor circuits. To demonstrate the advantages of the MISL platform, the shorted 3D metal stepped impedance resonators are first investigated using a miniaturized prototype based on this novel platform. Subsequently, a third‐order BPF based on MISL technology is designed, fabricated, and characterized. The fabricated BPF exhibits a minimum insertion loss (IL) of 0.31 dB, with centre frequencies of 5.88 GHz and 3‐dB fractional bandwidths of 19.8%, respectively.
A reliability‐based construction approach for wide‐area backup protection systems utilizing phasor measurement units in smart grids

Published: January 2024

AbstractReliability is a fundamental requirement of wide‐area backup protection (WABP) systems, and it is one of the most crucial performance indicators for such a WABP system. Two definitions are introduced: the reliability of WABP systems and the undetectable probability of a power line. They are determined by the specific placement of communication links (CLs) and phasor measurement units (PMUs). A simultaneous optimization model was developed to minimize the construction cost of WABP systems by optimizing the partitioning and placement of PMUs, protection centers, and CLs. The model considers several constraints, including latency, regional balance, and system reliability. To reduce the computational complexity, a cluster‐based genetic algorithm was developed to determine the optimal solution. Finally, numerical simulations were conducted using IEEE test cases. The results demonstrate that the proposed method can minimize the construction costs of WABP systems while increasing their reliability.

Published: January 2024

Context. The modelling of chemical transport mechanisms is crucial for accurate stellar characterisations. Atomic diffusion is one of these processes and is commonly included in stellar models. However, it is usually neglected for F-type or more massive stars because it produces surface abundance variations that are unrealistic. Additional mechanisms to counteract atomic diffusion must therefore be considered. It has been demonstrated that turbulent mixing can prevent excessive variation in surface abundances, and can also be calibrated to mimic the effects of radiative accelerations on iron.
Aims. We aim to evaluate the effect of calibrated turbulent mixing on the characterisation of a sample of F-type stars, and how the estimates compare with those obtained when chemical transport mechanisms are neglected.
Methods. We selected stars from two samples: one from the Kepler LEGACY sample and the other from a sample of Kepler planet-hosting stars. We inferred their stellar properties using two grids. The first grid considers atomic diffusion only in models that do not show excessive variation in chemical abundances at the stellar surface. The second grid includes atomic diffusion in all the stellar models and calibrated turbulent mixing to avoid unrealistic surface abundances.
Results. Comparing the derived results from the two grids, we find that the results for the more massive stars in our sample show greater dispersion in the inferred values of mass, radius, and age due to the absence of atomic diffusion in one of the grids. This can lead to relative uncertainties for individual stars of up to 5% on masses, 2% on radii, and 20% on ages.
Conclusions. This work shows that a proper modelling of the microscopic transport processes is crucial for the accurate estimation of their fundamental properties – not only for G-type stars but also for F-type stars.

Aims. Intense solar eruptions can produce solar energetic particles (SEPs), potentially detectable by ground-based instruments such as neutron monitors (NMs). These events are called ground-level enhancements (GLEs). The strongest GLE with the hardest known SEP spectrum occurred on 23 February 1956 (conventionally numbered GLE #5), providing a benchmark reference for related studies. However, the existing datasets for GLE #5 were compiled from different sources, often secondary; these datasets exhibited significant discrepancies and internal inconsistencies leading to large uncertainties or biases. Here we resolve the inconsistencies and revisit the reconstructions of the energy spectra and angular characteristics of the SEPs for that event, based on our reanalyses on (somehow forgotten) original contemporary records.
Methods. We collected, digitised, and verified the source records for NM measurements during GLE #5 based on contemporaneous publications and unpublished materials in the University of Chicago Archives. Using the revised datasets and full modelling, we critically revised the reconstruction of the energy spectra and angular characteristics of the SEPs and the event-integrated omnidirectional SEP flux (fluence) for GLE #5.
Results. The energy spectrum of the SEPs during the initial and main phases of GLE #5 was revised based on the new dataset, resulting in a slightly softer, but still agreeing within the uncertainties of the recent studies, SEP spectral estimate. The SEP flux was found to be highly anisotropic in the early phase of the event. This provides a revised reference basis for further analyses and modelling of strong and extreme SEP events and their terrestrial impacts.

Jean Blondel: One of the founding fathers of European political science
Authors: Cotta Maurizio 
Published: January 2024

AbstractJean Blondel’s personal and scientific biography deserves to be illustrated, as it can in many ways also be an illustration of the laborious making of a genuinely European (though not only) political science from the ashes of World War 2, and the failures (uncertainties) of pre-WWII political science. Here it will briefly be recalled how an enthusiastic and innovative institution builder gained a central place in the making of the new European political science, and how Blondel coupled this with his tireless exploration of new fields of comparative politics, while being at the same time a generous mentor of PhD students and younger scholars and, for many, a great friend.

Published: January 2024

Background Misinformation, defined as a claim that is false or misleading, considers information that is both shared with the intention of causing harm, and information that is false with no ill intent. Early attempts to downplay the risk of monkeypox (mpox) by singling out men who have sex with men (MSM) may have had the ill effect of stigmatising this group in discussions online. The aim of this study was to evaluate themes present on Instagram related to the 2022 mpox outbreak under #monkeypox. Specifically, this study sought to determine if the pervasive narratives surrounding the coronavirus disease 2019 (COVID-19) pandemic, particularly related to government mistrust and conspiracy, were penetrating discussions about mpox. Methods A total of 255 posts under #monkeypox (the top 85 posts per day, every 10 days in July 2022) were collected on Instagram. A content analysis approach, which seeks to quantify themes present, was utilised to evaluate themes present in posts under #monkeypox. Results Contrary to previous research investigating public health misinformation online, the majority of posts under #monkeypox were categorised as accurate information (85.9%). Moreover, a surprising number of posts were classified as anti-misinformation (32.9%), whereby users actively worked to debunk false information being shared online related to mpox. Conclusions We hypothesise that early labelling of the disease as one that strictly affects online MSM communities has resulted in the digital community coming together to fact-check and debunk misinformation under #monkeypox on Instagram.
Revealing incommensurability between device-independent randomness, nonlocality, and entanglement using Hardy and Hardy-type relations

Published: January 2024

Abstract
A comprehensive treatment of the quantification of randomness certified device-independently by using the Hardy and Cabello-Liang-Li (CLL) nonlocality relations is provided in the two parties-two measurements per party-two outcomes per measurement (2-2-2) scenario. For the Hardy nonlocality, it is revealed that for a given amount of nonlocality signified by a particular non-zero value of the Hardy parameter, the amount of Hardy-certifiable randomness is not unique, unlike the way the amount of certifiable randomness is related to the CHSH nonlocality. This is because any specified non-maximal value of Hardy nonlocality parameter characterises a set of quantum extremal distributions. Then this leads to a range of certifiable amounts of randomness corresponding to a given Hardy parameter. On the other hand, for a given amount of CLL-nonlocality, the certifiable randomness is unique, similar to that for the CHSH nonlocality. Furthermore, the tightness of our analytical treatment evaluating the respective guaranteed bounds for the Hardy and CLL relations is demonstrated by their exact agreement with the Semi-Definite-Programming based computed bounds. Interestingly, the analytically evaluated maximum achievable bounds of both Hardy and CLL-certified randomness have been found to be realisable for non-maximal values of the Hardy and CLL nonlocality parameters. In particular, we have shown that even close to the maximum 2 bits of CLL-certified randomness can be realised from non-maximally entangled pure two-qubit states corresponding to small values of the CLL nonlocal parameter. This, therefore, clearly illustrates the quantitative incommensurability between randomness, nonlocality and entanglement.

Published: January 2024

Abstract
Many researchers are working to improve the write operation in SRAM bit-cell for better write stability, low power dissipation, and minimal access time during the write process. However, the read and hold operation parameters should not be compromised to achieve these improvements. This paper presents a stable single-ended seven-carbon nanotube field-effect transistor (CNTFET) driven SRAM cell with improved write operation. The one-side inverter weakening approach for write and transistor decoupling for read operation leads to reduced dynamic power, low write delay, reduced leakage power, and improved stability. The proposed design is compared with conventional 6T (Conv6T) and three recently proposed designs, i.e., feedback-cutting 8T (feed-cut 8T), Low-power 8T and low-leakage 7T cell. The write delay and write PDP of the proposed design improve by 4.05×/3.58×/1.19×/1.21×and 11.11×/24.71×/2.96×/3.32×, respectively, compared to Conv6T/feed-cut 8T/ low-power 8T/ low-leakage 7T. Also, the read delay and read PDP of the proposed design improve by 1×/1.03×/1.72×/1.56× and 1×/1.03×/1.82×/1.77×, respectively, compared to Conv6T/feed-cut 8T/ low-power 8T/ low-leakage 7T. The leakage power of the proposed design is reduced by 1.08×/1.84×/0.46×/0.72× compared to Conv6T/feed-cut 8T/ low-power 8T/ low-leakage 7T. The noise margin of the proposed cell for hold/write/read operation is improved by 1.02×/1.05×/0.99×compared to the Conv6T design. The simulation was performed using Stanford University’s 32 nm CNTFET model on the cadence virtuoso platform.
Quantum phases of spin-1/2 extended XY model in transverse magnetic field
Authors: Malakar Rakesh Kumar , Ghosh Asim Kumar 
Published: January 2024

Abstract
In this study, a spin-1/2 extended anisotropic XY chain has been introduced in which both time reversal and SU(2) symmetries are broken but Z
2 symmetry is preserved. Magnetic and topological phase diagrams in the parameter space have been drawn in the presence of transverse magnetic field. Entanglement measures like mutual information and quantum discord are also evaluated and it indicates that these transitions are second order in nature. Quantum phase transition is noted at zero magnetic field, as well as magnetic long range order is found to withstand magnetic field of any strength. Exact analytic results for spin-spin correlation functions have been obtained in terms of Jordan-Wigner fermionization. Existence of long range magnetic order has been investigated numerically by finding correlation functions as well as the Binder cumulant in the ground state. Dispersion relation, ground state energy, and energy gap are obtained analytically. In order to find the topologically nontrivial phase, sign of Pfaffian invariant and value of winding number have been evaluated. Both magnetic and topological phases are robust against the magnetic field and found to move coercively in the parameter space with the variation of its strength. Long range orders along two orthogonal directions and two different topological phases are found and their one-to-one correspondence has been found. Finally casting the spinless fermions onto Majorana fermions, properties of zero energy edge states are studied. Three different kinds of Majorana pairings are noted. In the trivial phase, next-nearest-neighbor Majorana pairing is found, whereas two different types of nearest-neighbor Majorana pairings are identified in the topological superconducting phase.

Published: January 2024

Abstract

Objective. The number of electrode channels in a motor imagery-based brain–computer interface (MI-BCI) system influences not only its decoding performance, but also its convenience for use in applications. Although many channel selection methods have been proposed in the literature, they are usually based on the univariate features of a single channel. This leads to a loss of the interaction between channels and the exchange of information between networks operating at different frequency bands. Approach. We integrate brain networks containing four frequency bands into a multilayer network framework and propose a multilayer network-based channel selection (MNCS) method for MI-BCI systems. A graph learning-based method is used to estimate the multilayer network from electroencephalogram (EEG) data that are filtered by multiple frequency bands. The multilayer participation coefficient of the multilayer network is then computed to select EEG channels that do not contain redundant information. Furthermore, the common spatial pattern (CSP) method is used to extract effective features. Finally, a support vector machine classifier with a linear kernel is trained to accurately identify MI tasks. Main results. We used three publicly available datasets from the BCI Competition containing data on 12 healthy subjects and one dataset containing data on 15 stroke patients to validate the effectiveness of our proposed method. The results showed that the proposed MNCS method outperforms all channels (85.8% vs. 93.1%, 84.4% vs. 89.0%, 71.7% vs. 79.4%, and 72.7% vs. 84.0%). Moreover, it achieved significantly higher decoding accuracies on MI-BCI systems than state-of-the-art methods (paired t-tests, p < 0.05). Significance. The experimental results showed that the proposed MNCS method can select appropriate channels to improve the decoding performance as well as the convenience of the application of MI-BCI systems.

Published: January 2024

Abstract
The microstructure and properties of the Cu-Cr-Zr-Nb alloys prepared by non-vacuum melting and vacuum melting were compared and analyzed in this paper. The results showed that, compared with vacuum melting, the alloy prepared by non-vacuum melting had a more uneven microstructure and a coarser grain. In the meantime, the alloy prepared by non-vacuum melting stored less energy and had a lower proportion of HAGBs (high-angle grain boundaries), and the texture distribution along the TD and RD directions was not uniform. In terms of properties, the hardness and electrical conductivity of the Cu-Cr-Zr-Nb alloys prepared by non-vacuum melting were lower than those of the alloys prepared by vacuum melting. The electrical conductivity of the non-vacuum melting alloy was only 70.8 %IACS (International Annealed Copper Standard), and the average hardness fluctuated greatly. However, the electrical conductivity of the alloy prepared by vacuum melting could reach 81.0 %IACS, and the hardness was very uniform. Further research indicated that there were cracks and inclusions in the alloy prepared by non-vacuum melting. A large number of ZrO2 inclusions were found along the grain boundary, which demonstrated that the oxide inclusion was the primary cause of the crack formation. On this basis, three important suggestions for the preparation of the Cu-Cr-Zr-Nb alloys by non-vacuum melting were put forward to reduce the cost and improve the properties of the alloys. It provided guidance for developing high-performance Cu-Cr-Zr-Nb alloys by non-vacuum melting.

Published: January 2024

Abstract
The design and measurement results of ultra-low power, fast
10-bit Successive Approximation Register (SAR) Analog-to-Digital
Converter (ADC) prototypes in 65 nm CMOS technology are presented.
Eight prototype ADCs were designed using two different switching
schemes of capacitive Digital-to-Analog Converter (DAC), based on
MIM or MOM capacitors, and controlled by standard or low-power SAR
logic. The layout of each ADC prototype is drawn in 60 μm
pitch to make it ready for multi-channel implementation. A series of
measurements have been made confirming that all prototypes are fully
functional, and six of them achieve very good quantitative
performance. Five out of eight ADCs show both integral (INL) and
differential (DNL) nonlinearity errors below 1 LSB. In dynamic
measurements performed at 0.1 Nyquist input frequency, the effective
number of bits (ENOB) between 8.9–9.3 was obtained for different
ADC prototypes. Standard ADC versions work up to 80–90 MSps with
ENOB between 8.9–9.2 bits at the highest sampling rate, while the
low-power versions work up to above 50 MSps with ENOB around 9.3
bits at 40 MSps. The power consumption is linear with the sample
rate and at 40 MSps it is around 400 μW for the low-power
ADCs and just over 500 μW for the standard ADCs. At 80 MSps
the standard ADCs consume about 1 mW.
Gaussian diagrammatics from circular ensembles of random matrices
Authors: Novaes Marcel 
Published: January 2024

AbstractWe uncover a hidden Gaussian ensemble inside each of the three circular ensembles of random matrices, providing novel diagrammatic rules for the calculation of moments. The matrices involved are generic complex forβ = 2, complex symmetric forβ = 1 and complex self-dual forβ = 4, and at the last step their dimension must be set to1−2/β. As an application, we compute moments of traces of submatrices.
Deep learning application to automated classification of recommendations made by hospital pharmacists during medication prescription review
Authors: Alkanj Ahmad , Godet Julien , Johns Erin , Gourieux Bénédicte , Michel Bruno 
Published: January 2024

Abstract

Purpose
Recommendations to improve therapeutics are proposals made by pharmacists during the prescription review process to address suboptimal use of medicines. Recommendations are generated daily as text documents but are rarely reused beyond their primary use to alert prescribers and caregivers. If recommendation data were easier to summarize, they could be used retrospectively to improve safeguards for better prescribing. The objective of this work was to train a deep learning algorithm for automated recommendation classification to valorize the large amount of recommendation data.

Methods
The study was conducted in a French university hospital, at which recommendation data were collected throughout 2017. Data from the first 6 months of 2017 were labeled by 2 pharmacists who assigned recommendations to 1 of the 29 possible classes of the French Society of Clinical Pharmacy classification. A deep neural network classifier was trained to predict the class of recommendations.

Results
In total, 27,699 labeled recommendations from the first half of 2017 were used to train and evaluate a classifier. The prediction accuracy calculated on a validation dataset was 78.0%. We also predicted classes for unlabeled recommendations collected during the second half of 2017. Of the 4,460 predictions reviewed, 67 required correction. When these additional labeled data were concatenated with the original dataset and the neural network was retrained, accuracy reached 81.0%.

Conclusion
To facilitate analysis of recommendations, we have implemented an automated classification system using deep learning that achieves respectable performance. This tool can help to retrospectively highlight the clinical significance of daily medication reviews performed by hospital clinical pharmacists.
