Improved Resource‐Tunable Near‐Term Quantum Algorithms for Transition Probabilities, with Applications in Physics and Variational Quantum Linear Algebra
Authors: Sawaya Nicolas PD , Huh Joonsuk 
Published: July 2023

AbstractTransition amplitudes and transition probabilities are relevant to many areas of physics simulation, including the calculation of response properties and correlation functions. These quantities can also be related to solving linear systems of equations. This study presents three related algorithms for calculating transition probabilities. First, a previously published short‐depth algorithm is extended, allowing for the two input states to be non‐orthogonal. Building on this first procedure, a higher‐depth algorithm based on Trotterization and Richardson extrapolation is derived that requires fewer circuit evaluations. Third, a tunable algorithm that allows for trading off circuit depth and measurement complexity is introduced, yielding an algorithm that can be tailored to specific hardware characteristics. Finally, proof‐of‐principle numerics are presented for models in physics and chemistry and for a subroutine in variational quantum linear solving (VQLS). The primary benefits of these approaches are that a) arbitrary non‐orthogonal states may now be used with small increases in quantum resources, b) they (like another recently proposed method) entirely avoid subroutines such as the Hadamard test that may require three‐qubit gates to be decomposed, and c) in some cases fewer quantum circuit evaluations are required as compared to the previous state‐of‐the‐art in NISQ algorithms for transition probabilities.
An attitude cooperative control for multi‐spacecraft systems with arbitrary input delay time‐variation rate: A dynamic event‐triggered approach
Authors: Hu Hongsheng , Xu Hao , Meng Yunhe 
Published: July 2023

SummaryA problem of the attitude cooperative control of multi‐spacecraft systems with input time‐varying delay under an undirected graph is addressed in this paper, where the delay does not require any assumption on the continuity of the delay and its time‐variation rate. Considering the communication bandwidth constraint and Zeno behavior, a dynamic event‐triggered scheme is presented, which is more general than some existing event‐triggered schemes with a fixed threshold. By Lyapunov function technology, sufficient conditions of bilinear matrix inequality (BMI) for the existence of controller gain are proposed firstly such that the closed‐loop system is attitude cooperative with a new disturbance attenuation performance. It is also proved that there is a lower bound between two adjacent triggers via the mathematical analytical method, that is, the Zeno phenomenon can be avoided. Finally, the efficacy of the proposed methods is verified via simulations.

AbstractIn the present work, we have successfully developed polyaniline supported manganese dioxide (PANI/MnO2) nanocomposite using a facile and inexpensive approach under mild and green conditions by the PANI nanofiber sacrificial oxidation induced reductive conversion of KMnO4 as MnO2. The developed PANI/MnO2 adsorbent material was efficiently utilized for the removal of an organic dye Toluidine Blue (TB) from the aqueous samples.The fabricated adsorbent material was composed of the microstructures that possess grainy and fibrous morphology, and highly uneven surface textures. The FTIR, EDS, and XPS results show the presence of Mn, O, C, and N elements in the nanocomposite. Additionally, from XPS data the survival of the Mn+4 valance state of manganese was recognized. The nano‐thread deposited nano‐fibrous mesoporous nanocomposite holds a high BET surface area (168.096 m2 g−1), and pore volume (0.4428 cm3 g−1).The batch adsorption equilibrium studies showed that 97.51 % of the TB dye was eliminated in 70 min of sorption equilibrium at neutral pH with 92 mg/g of adsorption capacity. The kinetics of the adsorption process is finely portrayed by the pseudo‐second‐order (PSO) kinetic model and the adsorption mechanism is found to be concurrently controlled by intraparticle (IP) and film diffusion (FD) processes. The adsorption isotherm analysis studies revealed that the adsorption of TB dye over the developed PANI/MnO2 adsorbent material occurred with coverage of energetically equivalent binding sites by monolayer formation as substantiated by Langmuir isotherm.
Ball Milling Nanoarchitectonics of Nitrogen‐Doped Cr2O3 on Thermally Exfoliated. A. morphous Nanosheets for a High‐Performance Supercapacitor
Authors: Joseph Anit , Ramachandran Sindhu , Thomas Tiju 
Published: July 2023

AbstractThere is a growing interest in energy storage technologies that are “green”. In this context, supercapacitors are expected to play a vital role in addition to next‐generation batteries. The material chosen in this work is based on Cr2O3. This is because amorphous CrO3 is considered one of the best materials for high‐performance supercapacitors. This is due to its high specific capacity and specific surface area. In this work, we report a stable and efficient nitrogen‐doped Cr2O3 (N : Cr2O3) based electrode material. Undoped Cr2O3 in amorphous form is first synthesized via thermal exfoliation. It becomes crystalline when it is doped with nitrogen through ball milling. The phase obtained is N : Cr2O3. N : Cr2O3 is shown as a promising suitable material for electrochemical applications. This electrode material gives a specific capacitance of 1200 F/g at 1 A/g, 85 % cycle stability over 1000 cycles. The improved electrochemical performance of the N : Cr2O3 is due to the incorporation of nitrogen into its crystal structure.

Published: July 2023

AbstractA new cerium doped copper hybrid bimetallic organic framework (Ce/Cu‐BTC) was synthesized for oxidizing p‐diethylbenzene (PDEB) to p‐ethylacetophenone (EAP) in the batch and fixed‐bed reactors. The oxidization mechanism for PDEB to EAP over Ce/Cu‐BTC was investigated. Results show Ce/Cu‐BTC is a mischcrystal mixture of Ce‐BTC and Cu‐BTC, the addition of Ce can increase the crystal phase defects and enlarge the pore size of Cu‐BTC. The conversion rate of PDEB is above 95 % and the yield of EAP are stable at 75 % in the Ce/Cu‐BTC fixed bed reactor. A mixture of EAP, 1‐(4‐ethylphenyl)‐1‐ethanol (EPEA) and p‐diacetylbenzene (PDAB) can be detected in the outlet of the reactor. The PDEB with Ce4+/Cu2+, H2O2 and bromine free radical generate EPEA and EAP, the EAP is then further oxidized to PDAB. The mischcrystal structure of Ce/Cu‐BTC is beneficial to improve the catalytic oxidation activity and reaction rate of PDEB to EAP.

AbstractTechnological advancement makes the world a global village. Security is an evergreen and everlasting area, because of the continuous threat from Hackers and Crackers. The immense use of software systems has modernized human society in every aspect. Thus, it is crucial to devise new processes, techniques, and tools to support teams in the development of secure code from the early stages of the software development process, while potentially reducing the costs and shortening the time to market. Considering the significance of software security, it is important to consider the security practices from the early phase of the software development life cycle (SDLC), that is, requirements engineering (RE). Hence, this study aims to identify and categorize RE practices important to apply for secure software development (SSD) in a geographically distributed development environment. To study the RE practices concerning SSD, we conducted a questionnaire survey with industrial experts in the global software development (GSD) context.Furthermore, the interpretive structure modeling (ISM) approach was applied to evaluate the relationship between the RE security practice core categories. This paper identifies 70 practices and classifies them into 11 fundamental dimensions (categories) to assist GSD organizations in specifying the requirements for SSD. The ISM results show that the “Awareness of Secure Requirement Engineering (SRE)” category has the most decisive influence on the other 10 core categories of the identified RE security practices. With the help of empirical evidence and the ISM approach, this work attempts to identify potential security practices and to give a set of secure RE practices that can be used to improve the security of the software development process.
Iatrogenic pectus excavatum in a giant breed dog following median sternotomy
Authors: Santonocito Melissa , Levy Nyssa 
Published: July 2023

AbstractA giant breed dog was presented to a university teaching hospital for restlessness and what its owners perceived to be vomiting. The patient was subsequently diagnosed with spontaneous pneumothorax secondary to a pulmonary mass and underwent median sternotomy for lung lobectomy. Post‐operatively, the patient developed iatrogenic pectus excavatum, which likely contributed to morbidity and prolonged hospitalisation. A Hoyer lift was employed to assist patient mobility and limit external sternal compression from prolonged recumbency. This case highlights the potential for iatrogenic pectus excavatum, which may affect recovery in giant breed dogs post‐median sternotomy.

Published: July 2023

AbstractBackgroundThe goal of this study was to investigate factors associated with 30‐day readmission in a multivariate model, including the CDC wound classes “clean,” “clean/contaminated,” “contaminated,” and “dirty/infected.”MethodsThe 2017–2020 American College of Surgeons‐National Surgical Quality Improvement Program (ACS‐NSQIP) database was queried for all patients undergoing total hip replacement, coronary artery bypass grafting, Ivor Lewis esophagectomy, pancreaticoduodenectomy, distal pancreatectomy, pneumonectomy, and colectomies. ACS‐defined wound classes were concordant with CDC definitions. Multivariate linear mixed regression was used to determine risk factors for readmission while adjusting for type of surgery as a random intercept.Results477,964 cases were identified, with 38,734 (8.1%) patients having experienced readmission within 30 days of surgery. There were 181,243 (37.9%) cases classified as wound class “clean”, 215,729 (45.1%) cases classified as “clean/contaminated”, 40,684 cases (8.5%) classified as “contaminated”, and 40,308 (8.4%) cases classified as “dirty/infected”. In the multivariate generalized mixed linear model adjusting for type of surgery, sex, body mass index, race, American Society of Anesthesiologists class, presence of comorbidity, length of stay, urgency of surgery, and discharge destination, “clean/contaminated” (p < .001), “contaminated” (p < .001), and “dirty/infected” (p < .001) wound classes (when compared to “clean”) were significantly associated with 30‐day readmission. Organ/space surgical site infection and sepsis were among the most common reasons for readmission in all wound classes.ConclusionsWound classification was strongly prognostic for readmission in multivariable models, suggesting that it may serve as a marker of readmissions. Surgical procedures that are “non‐clean” are at significantly greater risk for 30‐day readmission. Readmissions may be due to infectious complications; optimizing antibiotic use or source control to prevent readmission are areas of future study.
Exploring the glycolytic cross-talk genes between inflammatory bowel disease and colorectal cancer

Published: July 2023

AbstractPatients with inflammatory bowel disease (IBD) have a higher risk of developing colorectal cancer (CRC). Glycolysis is involved in the development of both IBD and CRC. However, the mechanisms and outcomes of glycolysis shared between IBD and CRC remain unclear. This study aimed to explore the glycolytic cross-talk genes between IBD and CRC integrating bioinformatics and machine learning. With WGCNA, LASSO, COX, and SVM-RFE algorithms, P4HA1 and PMM2 were identified as glycolytic cross-talk genes. The independent risk signature of P4HA1 and PMM2 was constructed to predict the overall survival rate of patients with CRC. The risk signature correlated with clinical characteristics, prognosis, tumor microenvironment, immune checkpoint, mutants, cancer stemness, and chemotherapeutic drug sensitivity. CRC patients with high risk have increased microsatellite instability, tumor mutation burden. The nomogram integrating risk score, tumor stage, and age showed high accuracy for predicting overall survival rate. In addition, the diagnostic model for IBD based on P4HA1 and PMM2 showed excellent accuracy. Finally, immunohistochemistry results showed that P4HA1 and PMM2 were significantly upregulated in IBD and CRC. Our study reveals the presence of glycolytic cross-talk genes P4HA1 and PMM2 between IBD and CRC. This may prove to be beneficial in advancing research on the mechanism of development of IBD-associated CRC.

Published: July 2023

Abstract
Purpose
The osseous spiral lamina (OSL) is an inner cochlear bony structure that projects from the modiolus from base to apex, separating the cochlear canal into the scala vestibuli and scala tympani. The porosity of the OSL has recently attracted the attention of scientists due to its potential impact on the overall sound transduction. The bony pillars between the vestibular and tympanic plates of the OSL are not always visible in conventional histopathological studies, so imaging of such structures is usually lacking or incomplete. With this pilot study, we aimed, for the first time, to anatomically demonstrate the OSL in great detail and in 3D.

Methods
We measured width, thickness, and porosity of the human OSL by microCT using increasing nominal resolutions up to 2.5-µm voxel size. Additionally, 3D models of the individual plates at the basal and middle turns and the apex were created from the CT datasets.

Results
We found a constant presence of porosity in both tympanic plate and vestibular plate from basal turn to the apex. The tympanic plate appears to be more porous than vestibular plate in the basal and middle turns, while it is less porous in the apex. Furthermore, the 3D reconstruction allowed the bony pillars that lie between the OSL plates to be observed in great detail.

Conclusion
By enhancing our comprehension of the OSL, we can advance our comprehension of hearing mechanisms and enhance the accuracy and effectiveness of cochlear models.
Multi-GNSS precise point positioning with predicted orbits and clocks

Published: July 2023

AbstractGlobal Navigation Satellite Systems (GNSS) Real-time Precise Point Positioning (RT-PPP) strongly relies on the precise satellite orbits and clocks, especially the latter requires high update rate, e.g., five seconds, due to its limited prediction accuracy. Such a high-rate update frequency is a burden to both the data analysis and communicating, and interruption in communicating is almost unavoidable. For the new constellations such as Galileo and BDS-3 with high-stability hydrogen clocks onboard, it is possible to predict satellite clocks to a longer arc. Moreover, recent developments in multi-GNSS ultra-rapid precise orbit determination enables the half-hourly update, ensuring the availability with a prediction arc of 30–60 min. We investigate multi-GNSS RT-PPP using half-hourly predicted products and demonstrate that a 3-D accuracy of 2.9 and 11.3 cm can be achieved for static and simulated kinematic solutions, respectively. We present the different clock prediction accuracies of different types of satellites and propose a satellite-specific weighting strategy in PPP, which exploits the benefits of the satellites of good performance. The method is based on the prediction accuracy of both, satellites and clocks, and shows an improvement of 15 to 60% compared to those without satellite-specific weighting or with simplified weighting strategies. We also demonstrate that Galileo satellites contribute the most in the quad-constellation solution, thanks to the highly stable satellite clocks.
Topologically Semiperfect Topological Rings

Published: July 2023

AbstractWe define topologically semiperfect (complete, separated, right linear) topological rings and characterize them by equivalent conditions. We show that the endomorphism ring of a module, endowed with the finite topology, is topologically semiperfect if and only if the module is decomposable as an (infinite) direct sum of modules with local endomorphism rings. Then we study structural properties of topologically semiperfect topological rings and prove that their topological Jacobson radicals are strongly closed and the related topological quotient rings are topologically semisimple. For the endomorphism ring of a direct sum of modules with local endomorphism rings, the topological Jacobson radical is described explicitly as the set of all matrices of nonisomorphisms. Furthermore, we prove that, over a topologically semiperfect topological ring, all finitely generated discrete modules have projective covers in the category of modules, while all lattice-finite contramodules have projective covers in both the categories of modules and contramodules. We also show that the topological Jacobson radical of a topologically semiperfect topological ring is equal to the closure of the abstract Jacobson radical, and present a counterexample demonstrating that the topological Jacobson radical can be strictly larger than the abstract one. Finally, we discuss the problem of lifting idempotents modulo the topological Jacobson radical and the structure of projective contramodules for topologically semiperfect topological rings.

Published: July 2023

AbstractRemoval of the mesial temporal lobe (MTL) is an established surgical procedure that leads to seizure freedom in patients with intractable MTL epilepsy; however, it carries the potential risk of memory damage. Neurofeedback (NF), which regulates brain function by converting brain activity into perceptible information and providing feedback, has attracted considerable attention in recent years for its potential as a novel complementary treatment for many neurological disorders. However, no research has attempted to artificially reorganize memory functions by applying NF before resective surgery to preserve memory functions. Thus, this study aimed (1) to construct a memory NF system that used intracranial electrodes to feedback neural activity on the language-dominant side of the MTL during memory encoding and (2) to verify whether neural activity and memory function in the MTL change with NF training. Two intractable epilepsy patients with implanted intracranial electrodes underwent at least five sessions of memory NF training to increase the theta power in the MTL. There was an increase in theta power and a decrease in fast beta and gamma powers in one of the patients in the late stage of memory NF sessions. NF signals were not correlated with memory function. Despite its limitations as a pilot study, to our best knowledge, this study is the first to report that intracranial NF may modulate neural activity in the MTL, which is involved in memory encoding. The findings provide important insights into the future development of NF systems for the artificial reorganization of memory functions.
An empirical study of vulnerabilities in edge frameworks to support security testing improvement
Authors: Malik Jahanzaib , Pastore Fabrizio 
Published: July 2023

AbstractEdge computing is a distributed computing paradigm aiming at ensuring low latency in modern data intensive applications (e.g., video streaming and IoT). It consists of deploying computation and storage nodes close to the end-users. Unfortunately, being distributed and close to end-users, Edge systems have a wider attack surface (e.g., they may be physically reachable) and are more complex to update than other types of systems (e.g., Cloud systems) thus requiring thorough security testing activities, possibly tailored to be cost-effective. To support the development of effective and automated Edge security testing solutions, we conducted an empirical study of vulnerabilities affecting Edge frameworks. The study is driven by eight research questions that aim to determine what test triggers, test harnesses, test oracles, and input types should be considered when defining new security testing approaches dedicated to Edge systems. preconditions and inputs leading to a successful exploit, the security properties being violated, the most frequent vulnerability types, the software behaviours and developer mistakes associated to these vulnerabilities, and the severity of Edge vulnerabilities. We have inspected 147 vulnerabilities of four popular Edge frameworks. Our findings indicate that vulnerabilities slip through the testing process because of the complexity of the Edge features. Indeed, they can’t be exhaustively tested in-house because of the large number of combinations of inputs, outputs, and interfaces to be tested. Since we observed that most of the vulnerabilities do not affect the system integrity and, further, only one action (e.g., requesting a URL) is sufficient to exploit a vulnerability
Visual Low-Code Language for Orchestrating Large-Scale Distributed Computing

Published: July 2023

AbstractDistributed, large-scale computing is typically performed using textual general-purpose programming languages. This requires significant programming skills associated with the parallelisation and distribution of computations. In this paper, we present a visual (graphical) programming language called the Computation Application Language (CAL) to raise abstraction in distributed computing. CAL programs define computation workflows by visualising data flowing between computation units. The goal is to reduce the amount of traditional code needed and thus facilitate development even by non-professional programmers. The language follows the low-code paradigm, i.e. its implementation (the editor and the runtime system) is available online. We formalise the language by defining its syntax using a metamodel and specifying its semantics using a two-step approach. We define a translation of CAL into an intermediate language which is then defined using an operational approach. This formalisation was used to develop a programming and execution environment. The environment orchestrates computations by interpreting the intermediate language and managing the instantiation of computation modules using data tokens. We also present an explanatory case-study example that shows a practical application of the language.
