Anti-persistent adherence dynamic of the COVID-19 vaccines
Authors: Fernandes Leonardo H S , Silva Maria A R , de Araújo Fernando H A 
Published: December 2022

Abstract
This research explores the multifractal dynamics of time series of the daily number of vaccinees for COVID-19, considering six European countries (Belgium, Denmark, France, Germany, Greece and Italy) using the Multifractal Detrended Fluctuations Analysis (MF-DFA). We calculate the multifractal spectrum f(α) and apply a fourth-degree polynomial regression fit to estimate the complexity parameters that describe the degree of multifractality of the underlying process. We found that the multifractal dynamics of all these countries are characterized by strongly anti-persistent behavior (α
0 < 0.5) a lower degree of multifractality, and small fluctuations are dominant in the multifractal spectrum. From an immunization perspective, it means that a panorama that encompasses the population’s behaviour is marked by the dynamics of anti-persistent adherence to COVID-19 vaccines. Our findings confirm that the period of immunization of the population that adhered to the vaccination campaigns is short and that the application of new doses of vaccines must obey this phenomenology to keep people safe. In addition, we used the multifractal efficiency coefficient to rank countries that are most proactive in developing campaigns that promote greater adherence and loyalty to COVID-19 vaccines. Our findings indicate that Germany, Belgium and France were more efficient than Greece, Denmark and Italy.

Abstract
Nickel ditelluride (NiTe2), a newly discovered type-II Dirac semimetal whose Dirac node lies in proximity to the Fermi level, is expected to exhibit exotic phenomena including the pressure-driven Lifshitz transition and novel superconductivity in the monolayer limit. It is known that defects are commonly seen in transition metal dichalcogenides and have remarkable impacts on their optical and electronic properties. However, the systematic study on defects in NiTe2 remains to be explored. Here, by using high-resolution scanning tunneling microscopy combined with the first-principles calculations, the structure and electronic properties of atomic defects in NiTe2 have been systematically investigated. Specifically, we identified five distinct types of atomic defects, involving the vacancy and the intercalation. Our results indicate that the metal intercalation defect is the predominant one due to its lowest formation energy, which differs substantially from the case in MoS2 and PtSe2. It is further revealed that the topological surface states are surprisingly robust against these atomic defects. Our results demonstrate that the electronic properties of NiTe2, especially its topological surface states, are very robust, which may be important for its future applications in microelectronics.
Uncertainty relation based on metric-adjusted skew information with quantum memory
Authors: Ren Ruonan , Li Yongming 
Published: December 2022

Abstract
The uncertainty principle is one of the most essential features of quantum mechanics. Recently, uncertainty relations of skew information have been widely studied. In this paper, general and conditional uncertainty relations based on metric-adjusted skew information are put forward to study the case of the uncertainty relation with the existence of a quantum memory for the bipartite quantum system. These uncertainty relations include the product form and the sum form. The results show that the lower bounds contain two parts: one is characterizing the degree of compatibility of two measurements, and the other one is the quantum correlation between the measured system and the quantum memory. These results may play an important role in witnessing entanglement and quantum key distribution.
Optical parametric oscillator with quantum memory for quantum repeaters
Authors: Akat’ev D O , Kalachev A A 
Published: December 2022

Abstract
We consider preparing entangled states between single photons and quantum memory by combining two-photon source based on spontaneous parametric down-conversion and multiatomic quantum memory in a common resonator. The scheme allows one to minimize the losses while the photon to be stored is propagating from the source to the quantum memory and avoids the need to synchronize their operating wavelength. In this respect, the scheme is analogous to the cavity-enhanced embedded memory within Duan-Lukin-Cirac-Zoller approach, but it remains possible to generate a second photon at the wavelength of the fiber optic communication channel and use various multiplexing methods inherent in multiatomic quantum memory.

In the case of an n = 4 RSAE, where n is the toroidal mode number, this magnetic fluttering nonlinearity leads to strong mode coupling and broadening of the saturation spectrum. The nonlinear components, which are highly damped through the interaction between thermal electrons and the parallel electric field, modifies the RSAE mode structure and suppresses energetic particle drive significantly.

Dynamics of the τ-Wigner distribution function
Authors: Spisak B J , Wozniak D , Kolaczek D 
Published: December 2022

Abstract
Some of the non-classical distribution functions defined on the phase space can be unified owing to specific parameterization. The latter allows one to think about the general form of the equation of motion (EOM) for such parameterized distribution functions. Motivated by this idea, we derive the EOM for so-called the τ-Wigner distribution function (WDF). This parameterization directly results from a modification of the linear transformation of the spatial variables which is used to derive the original WDF and its EOM. The derived equation is analytically solved for the case of linear potential. The point symmetries of this last equation are also analyzed.
Youth movements, intergenerational justice, and climate litigation in the deep time context of the Anthropocene
Authors: Kotzé Louis J , Knappe Henrike 
Published: December 2022

Abstract
After decades of ineffective state-led global climate governance that has been dominated by mostly short-term Northern political and corporate interests, we are now witnessing an increased recognition of the planetary scale of the climate crisis and its impacts on present and future life on Earth. The Anthropocene is argued to be the new geological epoch and is associated with fast-approaching planetary boundaries and a new understanding of promethean humans as a powerful geological force. The Anthropocene introduces a new context for thinking about the climate crisis and its associated multiple patterns of differentially distributed injustices, including the temporal aspects of justice. At the same time, the climate crisis prompts the need to embark on new strategies to ensure a safe and just operating space for all present and future generations within planetary limits. While traditionally marginalized in national, regional and United Nations political fora, and largely ignored by the high rhetoric of multilateral environmental agreements that have been unable to operationalize intergenerational justice in day-to-day governance, young people are now actively claiming their position as representatives of present and future generations. They do so through protests, but also through more formal avenues to deliberately assert claims for intergenerational justice. One increasingly popular and often successful strategy is climate litigation. In this paper, we explore the shift in understanding and the practicing of intergenerational justice in the deep time context of the Anthropocene, and how young people are becoming more powerful political actors that use climate litigation to ensure intergenerational justice. We briefly reflect on the 2021 decision of the German Constitutional Court in Neubauer et al versus Germany as an example of successful youth-led climate litigation.

Abstract
Barium zirconium sulfide (BaZrS3) is an earth-abundant and environmentally friendly chalcogenide perovskite with promising properties for various energy conversion applications. Recently, sulfurization of oxide precursors has been suggested as a viable solution for effective synthesis, especially from the perspective of circumventing the difficulty of handling alkali earth metals. In this work, we explore in detail the synthesis of BaZrS3 from Ba-Zr-O oxide precursor films sulfurized at temperatures ranging from 700 °C to 1000 °C. We propose a formation mechanism of BaZrS3 based on a two-step reaction involving an intermediate amorphization step of the BaZrO3 crystalline phase. We show how the diffusion of sulfur (S) species in the film is the rate-limiting step of this reaction. The processing temperature plays a key role in determining the total fraction of conversion from oxide to sulfide phase at a constant flow rate of the sulfur-containing H2S gas used as a reactant. Finally, we observe the formation of stoichiometric BaZrS3 (1:1:3), even under Zr-rich precursor conditions, with the formation of ZrO2 as a secondary phase. This marks BaZrS3 quite unique among the other types of chalcogenides, such as chalcopyrites and kesterites, which can instead accommodate quite a large range of non-stoichiometric compositions. This work opens up a pathway for further optimization of the BaZrS3 synthesis process, straightening the route towards future applications of this material.
Grinding temperature and its consequences on induced residual stresses during grinding of nickel-based superalloys: a review
Authors: Gupta Shambhu Nath , Chak Sanjay Kumar 
Published: December 2022

Abstract
Considering the high tool wear and time limits for the machining of tough-to-machine materials, the grinding process is economically preferred over traditional milling, turning, and drilling procedures. The grinding process offers a more refined surface finish, high tolerances and is suitable for machining difficult-to-machine materials like nickel-based superalloy. High-Temperature application components used for aerospace industries always impose thermal problems due to their high corrosion resistance and low thermal conductivity which largely influence the surface integrity during machining of nickel-based superalloys. Various techniques for grinding temperature measurement in the contact zone of wheel-workpiece and the effects of process parameters on grinding temperature and induced residual stresses are described in this paper. A comprehensive review has been carried out to control thermal damage due to high heat generation and its correlations with the induced residual stress on the ground surface during grinding of Ni-based superalloys by optimizing the grinding parameters.
Aligning sustainability and regional earthquake hazard mitigation planning: integrating greenhouse gas emissions and vertical equity
Authors: Kavvada Ioanna , Moura Scott , Horvath Arpad 
Published: December 2022

Abstract
Concerns about the potential economic consequences of earthquakes have increased in recent years as scientifically based probabilities of future earthquakes in many large urban areas have risen. These hazards disproportionately impact low-income communities as wealth disparities limit their capacity to prepare and recover from potentially disastrous events. In addition to major economic losses, the activities related to building recovery result in significant greenhouse gas emissions contributing to climate change. This article develops a framework that quantifies the complex relationships between pre-earthquake retrofit activities and their economic, environmental and equity implications to promote informed decision-making, using the city of San Francisco, California as a case study. This research consists of two sections. In the first section, a bi-objective optimization model is proposed to identify optimal earthquake risk mitigation policies to minimize total earthquake-related economic and environmental costs, simultaneously. Decisions entail the seismic retrofit, combined seismic and energy retrofit or complete reconstruction of building-type groups. The benefits of increased energy efficiency of the upgraded buildings are incorporated to evaluate decisions from a holistic perspective. In the second section, the model is extended to address the issue of inequitable budget allocation from a public-sector perspective. Vertical equity considerations are incorporated as an optimization constraint to distribute available resources aiming to limit the discrepancy of expected losses as a fraction of income between households across income groups. The tradeoff between equity and economic efficiency is explored. Results show that life-cycle environmental impacts constitute an informative performance metric to regional risk mitigation decision-makers, in addition to the more customarily used monetary losses. Although construction costs primarily dictate optimal decisions from an economic perspective, energy considerations largely impact optimal decisions from an environmental perspective.

AbstractObjectivesMicro–computed tomography (micro-CT) is a novel, nondestructive, slide-free digital imaging modality that enables the acquisition of high-resolution, volumetric images of intact surgical tissue specimens. The aim of this systematic mapping review is to provide a comprehensive overview of the available literature on clinical applications of micro-CT tissue imaging and to assess its relevance and readiness for pathology practice.MethodsA computerized literature search was performed in the PubMed, Scopus, Web of Science, and CENTRAL databases. To gain insight into regulatory and financial considerations for performing and examining micro-CT imaging procedures in a clinical setting, additional searches were performed in medical device databases.ResultsOur search identified 141 scientific articles published between 2000 and 2021 that described clinical applications of micro-CT tissue imaging. The number of relevant publications is progressively increasing, with the specialties of pulmonology, cardiology, otolaryngology, and oncology being most commonly concerned. The included studies were mostly performed in pathology departments. Current micro-CT devices have already been cleared for clinical use, and a Current Procedural Terminology (CPT) code exists for reimbursement of micro-CT imaging procedures.ConclusionsMicro-CT tissue imaging enables accurate volumetric measurements and evaluations of entire surgical specimens at microscopic resolution across a wide range of clinical applications.
Implementation of radio-frequency identification technology to optimize medication inventory management in the intraoperative setting
Authors: Wilke Carlie , Bowden Ashley , Sanders Tom , Nickman Nancy A , Ashmead Payson 
Published: December 2022

AbstractPurposeManual restocking and tracking of noncontrolled medications in anesthesia workstations (AWSs) is complicated and time intensive, provides several opportunities for error, and lacks perpetual inventory transparency regarding expiration and lot number. This pre-post study assessed the impact of radio-frequency identification (RFID) technology on restocking of noncontrolled medications in AWSs in relation to workflow, improved patient safety due to reduced restocking errors, and restocking accuracy and efficiency, as well as the estimated costs of on-site medication RFID tagging versus purchase of pretagged products.SummaryPre- and postimplementation process steps were mapped. Randomized AWS tray audits were conducted to assess patient safety, and AWS tray restocking efficiency was measured through stopwatch studies. Time and costs associated with purchase of manufacturer RFID tagged medications versus manually tagging medications on-site were estimated. Pre-post comparisons were completed using descriptive statistics. Prior to implementation, manual AWS restocking took a mean (SD) of 37.9 (24.7) seconds (range, 4.6-135.9 seconds), compared to 145.9 (50.6) seconds (range, 43.4-314.3 seconds) after implementation. The automated workflow took technicians an average of 108 seconds (1.8 minutes) longer than the baseline time. However, restocking errors were reduced by 64.7% and outdated and missing medications eliminated. Manually applying tags to packages containing 25 vials took a mean (SD) of 174.8 (19.8) seconds (range, 131-218 seconds) for smaller vials, compared to 128.1 (21.6) seconds (range, 102-166 seconds) for larger vials. Manual tag application was also more expensive than purchasing of pretagged vials.ConclusionAutomated RFID technology for AWS restocking decreased restocking errors but increased the length of time to complete the restocking process.
Quantum Guess and Determine Attack on Stream Ciphers
Authors: Ding Lin , Wu Zheng , Zhang Guixian , Shi Tairong 
Published: December 2022

Abstract
To guarantee the security of symmetric key schemes against quantum adversary, developing quantum cryptanalytic techniques becomes a major worldwide challenge in the post-quantum world. In this paper, we present a general framework of classical guess and determine attack on stream ciphers, and then convert it into quantum guess and determine attack. It shows that, for a given stream cipher with a key size of $k$ bits and an internal state size of $n$ bits, if a basic guess and determine attack with a time complexity below $O ( {{{2}^{{3k}/{2}}}}/{n} )$ is available, there is a quantum guess and determine attack with multiple data that can recover all $n$ internal state bits of the cipher with complexity below $O ( {{2^{k / 2}}} )$. As applications, we present quantum guess and determine attacks on the SNOW-like stream ciphers. The results show that all of SNOW 1.0 with 128-bit key, SNOW 2.0 with 128-bit key and SOSEMANUK are insecure against quantum guess and determine attack. The resource requirements for implementing a quantum guess and determine attack on SNOW 3G are evaluated as a case study. To the best of our knowledge, this is the first time that the general quantum guess and determine attack is formally proposed and applied to the SNOW-like stream ciphers.
Stellate ganglion blockade combined with nifekalant for patients with electrical storm: a case report
Authors: Kiyohara Takuya , Sakaguchi Kenta , Maeda Daichi , Hoshiga Masaaki 
Published: December 2022

Abstract

Background
Although both stellate ganglion blockade and nifekalant are effective treatment options for electrical storm, the clinical effect of their combination is uncertain.

Case summary
A 71-year-old male patient was admitted to our hospital with acute myocardial infarction and heart failure. Emergency coronary angiography revealed triple-vessel disease. Although coronary artery bypass grafting was planned, the patient experienced electrical storm before the surgery could be performed. Despite complete revascularization by percutaneous coronary intervention, mechanical circulatory support and administration of antiarrhythmic agents (amiodarone and lidocaine), electrical storm was not controlled. After stellate ganglion blockade was initiated on the 9th day of hospitalization, ventricular arrhythmia decreased. However, when stellate ganglion blockade was temporarily discontinued, ventricular arrhythmia increased substantially. Subsequently, combination therapy with stellate ganglion blockade and nifekalant was initiated, after which ventricular arrhythmia disappeared completely. Afterwards, the patient had no further ventricular arrhythmia episodes, and his haemodynamic status gradually improved. The patient was discharged from hospital in an ambulatory condition and did not experience arrhythmia during the follow-up.

Discussion
This case demonstrates that combination therapy with stellate ganglion blockade and nifekalant can completely suppress ventricular arrhythmia, suggesting that blocking multiple conduction pathways is a key to treating refractory electrical storm.
Diastolic heart failure is a new clinical entity of trastuzumab-induced cardiotoxicity: a case report
Authors: Fujita Kana , Matsumoto Kensuke , Kishi Atsuhiko , Kawasaki Satoru 
Published: December 2022

Abstract

Background
Cancer therapy-related cardiac dysfunction (CTRCD) is defined as a decrease in the left ventricular ejection fraction (LVEF) of &gt;10% to a value below the lower limit of normal or relative reduction in global longitudinal strain (GLS) &gt;15% from baseline after cancer treatment. However, the possibility of the development of isolated diastolic dysfunction has never been considered in the clinical presentation of CTRCD.

Case summary
An 81-year-old woman was admitted to our institution presenting with prominent bilateral leg oedema, orthopnoea, and 8 kg of weight gain after administration of the anti-human epidermal growth factor receptor 2 (HER-2) antibody, trastuzumab, for HER-2-positive breast cancer. Transthoracic echocardiography showed a preserved LVEF of 62% without a significant reduction in GLS compared with results obtained before anti-HER-2 targeted therapy. Doppler echocardiography distinctly revealed a newly developed significant left ventricular diastolic dysfunction with evidence of elevated filling pressure. After successful achievement of volume reduction, the patient underwent cardiac catheter examination, revealing an elevated pulmonary artery wedge pressure of 18 mmHg. Subsequently, trastuzumab was discontinued and the patient was treated with diuretics, arteriodilators, and venodilators, until the signs and symptoms of heart failure completely disappeared.

Discussion
In the management of CTRCD, including pretreatment screening, cardiotoxicity monitoring, follow-up after anti-cancer agents, and evaluation of the effectiveness of the therapy, too much emphasis has been paid exclusively to the development of systolic dysfunction; however, perspectives for diastolic dysfunction may be needed. A comprehensive multidisciplinary team approach composed of breast surgeons, oncologists, onco-cardiologists, and echocardiography specialists is required.
