A Fundamental Mechanism of Solar Eruption Initiation in a Multipolar Magnetic Field
Authors: Bian Xinkai , Jiang Chaowei , Feng Xueshang , Zuo Pingbing , Wang Yi
Published: October 2023

Recently, we established a fundamental mechanism of solar eruption initiation in which an eruption can be initiated from a bipolar field through magnetic reconnection in the current sheet (CS) that is formed slowly in the core field as driven by photospheric shearing motion. Here, using a series of fully 3D MHD simulations with a range of different photospheric magnetic flux distributions, we extended this fundamental mechanism to the quadrupolar magnetic field containing a null point above the core field, which is the basic configuration of the classical breakout model. As is commonly believed, in such a multipolar configuration, the reconnection triggered in the CS originated at the null point (namely, the breakout reconnection) plays the key role in eruption initiation by establishing a positive feedback loop between the breakout reconnection and the expansion of the core field. However, our simulation showed that the key to eruption initiation in such a multipolar configuration remains the slow formation of the CS in the sheared core, rather than the onset of fast breakout reconnection. The breakout reconnection only helps the formation of the core CS by letting the core field expand faster, but the eruption cannot occur when the bottom surface driving is stopped well before the core CS is formed, even though the fast reconnection has already been triggered in the breakout CS. This study clarified the role of breakout reconnection and confirmed formation of the core CS as the key to the eruption initiation in a multipolar magnetic field.

A detailed analysis of the nuclear star cluster not only concedes the existence of the S cluster, with its fast-moving stars and the supermassive black hole Sgr A*. It also reveals an embedded region of gas and dust with an exceptionally high stellar density called IRS 13. The IRS 13 cluster can be divided into the northern and eastern counterparts, called IRS 13N and IRS 13E, respectively. This work will focus on both regions and study their most prominent members using rich infrared and radio/submillimeter data baselines. Applying a multiwavelength analysis enables us to determine a comprehensive photometric footprint of the investigated cluster sample. Using the ray-tracing-based radiative transfer model HYPERION, the spectral energy distribution of the IRS 13 members suggests a stellar nature of the dusty sources. These putative young stellar objects (YSOs) have a comparable spectroscopic identification to the D and G sources in or near the S cluster. Furthermore, we report the existence of a population of dusty sources in IRS 13 that can be mostly identified in the H, K, and L band. We propose that, together with the objects reported in the literature, this population is the outcome of a recent star formation process. Furthermore, we report that these presumably young objects are arranged in a disk structure. Although it cannot be excluded that the intrinsic arrangement of IRS 13 does show a disk structure, we find indications that the investigated cluster sample might be related to the counterclockwise disk.

Published: October 2023

We systematically investigate the mergers of neutron star–white dwarf binaries from beginning to end, with a focus on the properties of the inflows and outflows in accretion disks and their electromagnetic emissions. Using population synthesis models, we determine a subset of these binaries in which the white dwarf companion undergoes unstable mass transfer and complete tidal disruption, forming a large accretion disk around the neutron star. The material evolves according to a one-dimensional advection-dominated accretion-disk model with nuclear burning, neutrino emissions, and disk-surface wind ejection. The extreme dynamics of the entire process have proven difficult to analyze, and thus currently, the properties are poorly understood. The outflows from the mergers are iron- and nickel-rich, giving rise to optical and infrared emissions powered by the decay of the radioactive iron-type isotopes, calculated via the SuperNu light-curve code. We find these systems capable of powering bright, yet short-lived, optical transients with the potential to power gamma-ray bursts.

Published: October 2023

BACKGROUND: Coagulopathy in coronavirus disease 2019 (COVID-19) patients causes a prothrombotic state that increases the risk of thromboembolism. The Padua score and coagulopathy parameter including D-dimer values, fibrinogen, prothrombin time (PT), activated partial thromboplastin time (aPTT), and platelet counts are very important parameters to determine risk of thrombosis and mortality in hospitalized COVID-19 patients.
AIM: This study aimed to assess the prognosis of COVID-19 patients with Padua score and coagulopathy parameters.
METHODS: This retrospective cohort study was conducted in tertiary university hospital, Prof. Dr. R. D. Kandou Hospital Manado, Indonesia from October 2020 to July 2021. Patients admitted with final diagnosis of COVID-19 confirmed with positive reverse transcriptase-polymer chain reaction test were included in the study. The data were refined by excluding the patients under 18 years old and the patients with no blood test results, D-dimer values, fibrinogen values, PT values, aPTT values, and platelet counts. The association of Padua score and coagulopathy parameters with survival of COVID-19 patients was analyzed by multivariate cox regression and Kaplan–Meier analysis.
RESULTS: The probability of survival on day 14 in patients with Padua score <4, D-dimer <0.5 mg/dl, PT ≤16 s, aPTT ≤39 s, and platelets >150,000/μL was 100%, 100%, 84.6%, 81.5%, and 81.4%, respectively. COVID-19 survival was influenced by Padua score ≥4 (heart rate [HR] = 4.199; CI 95% 2.221–7.936), D-dimer ≥0.5 mg/L (HR = 4.772; CI 95% 2.244–10.147), PT >16 s (HR = 2.124; CI 95% 1.608–2.805), aPTT >39 s (HR = 1.449; CI 95% 1.080–1.943), and platelet count <150000/μL (HR = 2.056; CI 95% 1.489–2.840). Padua score has the highest probability of mortality compared to the other coagulopathy parameters (p < 0.001; HR = 3.655; CI 95% 1.927–6.932).
CONCLUSION: There was an association of Padua score, D-dimer value, PT value, aPTT value, and platelet count on survival of COVID-19 patients. Padua score being the most influential variable on survivals.

Loin de toute orthodoxie, de la passion au divan
Authors: Lecoq Arlette
Published: October 2023

Guidé par ses exigences de sincérité et par la turbulence de ses passions, Sándor Ferenczi ébranlera les limites de la psychanalyse naissante. Homme du XIX e  siècle mais moderniste avant la lettre, il va tracer un chemin d’ouverture tant sur le plan clinique que sur le plan théorique. Un pas de deux prometteur l’entraîne avec Freud vers des découvertes fécondes : l’introjection, Thalassa , etc. mais il s’écartera de son maître pour glisser vers l’étiologie traumatique des névroses que Freud avait abandonnée au profit de la voie fantasmatique. Ce tournant lui valut la mise au ban de la communauté analytique mais ouvrit la voie à travers de multiples douleurs, découvertes et échecs à la psychanalyse contemporaine.
Le journal clinique de Sándor Ferenczi. La psychanalyse du traumatisme
Authors: Hebbrecht Marc
Published: October 2023

L’article s’ouvre sur une discussion relative à la façon dont le journal a trouvé accès auprès du grand public. Il décrit ensuite les trois thèmes principaux du journal de Ferenczi : la relation de Ferenczi avec Freud, l’analyse mutuelle avec Elisabeth Severn (RN), enfin des considérations sur la thérapie de patients traumatisés ou victimes d’inceste, partie la plus importante du journal. Le traumatisme entraîne une fragmentation de la psyché en plusieurs parties. Ferenczi mentionne l’hypocrisie des parents, des éducateurs et des enseignants comme une cause importante du masochisme. En fin d’article, les implications thérapeutiques du traitement des victimes d’abus sexuels et d’inceste sont débattus.
Le traumatisme infantile, une confusion de langues historique entre Freud et Ferenczi
Authors: Franckx Christine
Published: October 2023

Sándor Ferenczi a apporté une innovation révolutionnaire en plaçant le statut du traumatisme infantile au centre du carrefour entre la réalité externe et la réalité intrapsychique, et donc au centre de discussions passionnées. Le contact avec ses propres traumatismes, probablement déclenchés par sa relation avec Freud, a été pour Ferenczi le moteur affectif de son travail de pionnier tout au long de sa vie. Des thèmes fondamentaux lui sont apparus très clairement au cours du processus d’émancipation de sa relation avec Freud, il les a décrits dans le célèbre texte de 1932, Confusion de langues entre les adultes et l’enfant. Le langage de la tendresse et de la passion. Ainsi, Ferenczi n’a pas seulement mis en évidence le rôle de l’objet primaire dans la constitution précoce de la psyché, il a également souligné l’importance d’une écoute contre-transférentielle ouverte, sincère et authentique. Le traumatisme infantile résulte, selon lui, d’un débordement émotionnel suite à l’impact d’une situation traumatique externe et enclenche un processus destructeur intrapsychique qui menace d’étouffer le Moi.
La théorie du réel comme « ontologie négative »
Authors: Espinosa Santiago
Published: October 2023

Dans cet article il s’agit de jeter quelque lumière sur les concepts de réel et de double dans l’œuvre de Clément Rosset. Il y est montré que ces deux concepts, fondamentaux pour sa pensée, ont toujours été clairement définis et déterminés, qu’ils n’ont pas prêté à confusion dans son œuvre, qu’ils ont toujours désigné chacun le même objet philosophique : ce qui existe et ce qui n’existe pas, respectivement. Le réel est l’ensemble de ce qui existe, qui peut être perçu ; le double est ce qui n’existe pas, qui ne peut donc être perçu ni pensé, mais qui n’en produit pas moins l’illusion d’une perception ou d’une pensée. À ce titre, l’article signale quelques malentendus ou contresens auxquels ces concepts ont pu prêter, non pas, encore une fois, en raison d’une définition faible ou vague, mais plutôt en raison d’une lecture orientée ou partielle de l’œuvre de Rosset.
Non-trivial solutions for a partial discrete Dirichlet nonlinear problem with $ p $-Laplacian
Authors: He Huiting , Ousbika Mohamed , El Allali Zakaria , Zuo Jiabin
Published: October 2023

We investigate the non-trivial solutions for a partial discrete Dirichlet nonlinear problem with $ p $-Laplacian by applying Ricceri's variational principle and a two non-zero critical points theorem. In addition, we identify open intervals of the parameter $ \lambda $ under appropriate constraints imposed on the nonlinear term. This allows us to ensure that the nonlinear problem has at least one or two non-trivial solutions.
Can infectious diseases eradicate host species? The effect of infection-age structure
Authors: Ponce Joan , Thieme Horst R.
Published: October 2023

It is a fundamental question in mathematical epidemiology whether deadly infectious diseases only lead to a mere decline of their host populations or whether they can cause their complete disappearance. Upper density-dependent incidences do not lead to host extinction in simple, deterministic SI or SIS (susceptible-infectious) epidemic models. Infection-age structure is introduced into SIS models because of the biological accuracy offered by considering arbitrarily distributed infectious periods. In an SIS model with infection-age structure, survival of the susceptible host population is established for incidences that depend on the infection-age density in a general way. This confirms previous host persistence results without infection-age for incidence functions that are not generalizations of frequency-dependent transmission. For certain power incidences, hosts persist if some infected individuals leave the infected class and become susceptible again and the return rate dominates the infection-age dependent infectivity in a sufficient way. The hosts may be driven into extinction by the infectious disease if there is no return into the susceptible class at all.

Published: October 2023

Immune infiltration plays a pivotal role in the pathogenesis of ischemic stroke. A novel form of cell death known as disulfidptosis has emerged in recent studies. However, there is currently a lack of research investigating the regulatory mechanism of disulfidptosis-related genes in immune infiltration during ischemic stroke. Using machine learning methods, we identified candidate key disulfidptosis-related genes (DRGs). Subsequently, we performed an analysis of immune cell infiltration to investigate the dysregulation of immune cells in the context of ischemic stroke. We assessed their diagnostic value by employing receiver operating characteristic (ROC) curves. To gain further insights, we conducted functional enrichment analyses to elucidate the signaling pathways associated with these seven DRGs. We identified two distinct subclusters based on the expression patterns of these seven DRGs. The unique roles of these subclusters were further evaluated through KEGG analysis and immune infiltration studies. Furthermore, we validated the expression profiles of these seven DRGs using both single-cell datasets and external datasets. Lastly, molecular docking was performed to explore potential drugs for the treatment of ischemic stroke. We identified seven DRGs. The seven DRGs are related to immune cells. Additionally, these seven DRGs also demonstrate potential diagnostic value in ischemic stroke. Functional enrichment analysis highlighted pathways such as platelet aggregation and platelet activation. Two subclusters related to disulfidptosis were defined, and functional enrichment analysis of their differentially expressed genes (DEGs) primarily involved pathways like cytokine-cytokine receptor interaction. Single-cell analysis indicated that these seven DRGs were primarily distributed among immune cell types. Molecular docking results suggested that genistein might be a potential therapeutic drug. This study has opened up new avenues for exploring the causes of ischemic stroke and developing potential therapeutic targets.

Characterization of Developed Agro-Based Adsorbents: A Study
Authors: Bhagat Rajesh , Khandeshwar Shantanu
Published: October 2023

Increased waste as a result of unsustainable industrialization, urbanization, and agriculturalization is a serious threat to the comfort of human life. Our ecosystem has been severely damaged by the production and disposal of massive amounts of harmful materials and pollutants. Technologies must be created to eliminate or drastically reduce hazardous waste and pollutants from the environment. By using agricultural waste and by-products to create environmentally acceptable adsorbents, adsorption is one way for removing pollutants from water and waste water. It is crucial to evaluate the capability of various produced adsorbents and determine how well they can be used to treat water and wastewater. To address this, research is being done on characterizing these materials. Proximate analysis, thermal gravimetric analysis, FTIR, SEM, energy dispersive X-ray analysis (EDS), BET surface area analysis, and X-ray diffraction are used to analyze agricultural wastes. According to XRD studies, agro-based adsorbents have an amorphous structure, which is a benefit for well-defined porous adsorbents. Development of good porosity occurred in all materials due to chemical treatment given to materials, which was evident from SEM images and results of BET analysis. Adsorbents prepared from agricultural wastes had large surface area ranging from 950-1200 m2/g, which makes them efficient adsorbents like conventionally used charcoal. EDS test results also shows that normal carbon content is in range 57 to 59% which is good for adsorption. Proximate analysis and bulk density also supported that developed adsorbents has the great potential. Agro-based adsorbents are efficient adsorbent which is a good alternative to conventionally and commercially available activated charcoal.

Published: October 2023

This case report describes a 54-year-old man who presented with abdominal discomfort, nausea, early satiety, and constipation. A CT scan revealed a large mass infiltrating the mesentery and close to bowel loops, raising suspicion of intestinal sub-occlusion. Urgent surgery was performed, resulting in a segmental jejunum resection to remove the identified mesenteric mass. Histological examination revealed a diagnosis of desmoid fibromatosis which is a rare type of soft tissue tumor with borderline malignancy that can cause bowel obstruction when it develops intra-abdominally. It is often associated with genetic predispositions and risk factors such as previous surgery and pregnancy. The case highlights the importance of considering a patient's surgical history when encountering desmoid fibromatosis to determine the most appropriate treatment approach.
Management of autofluorescence in formaldehyde-fixed myocardium: choosing the right treatment
Authors: Zhang Zhao , Fan Hongming , Richardson William , Gao Bruce Z. , Ye Tong
Published: October 2023

Autofluorescence (AF) poses challenges for detecting proteins of interest in situ when employing immunofluorescence (IF) microscopy. This interference is particularly pronounced in strongly autofluorescent tissues such as myocardium, where tissue AF can be comparable to IF. Although various histochemical methods have been developed to achieve effective AF suppression in different types of tissue, their applications on myocardial  samples have not been well validated. Due to inconsistency across different autofluorescent structures in sometypes of tissue, it is unclear if these methods can effectively suppress AF across all autofluorescent structures within the myocardium. Here, we quantitatively evaluated the performance of several commonly used quenching treatments on formaldehyde-fixed myocardial samples, including 0.3 M glycine, 0.3% Sudan Black B (SBB), 0.1% and 1% sodium borohydride (NaBH4), TrueVIEW® and TrueBlack®. We further assessed their quenching performance by employing the pre-treatment and post-treatment protocols, designed to cover two common IF staining scenarios where buffers contained detergents or not. The results suggest that SBB and TrueBlack® outperform other reagents in AF suppression on formaldehyde-fixed myocardial samples in both protocols. Furthermore, we inspected the quenching performance of SBB and TrueBlack® on major autofluorescent myocardial structures and evaluated their influence on IF imaging. The results suggest that SBB outperforms TrueBlack® in quenching major autofluorescent structures, while TrueBlack® excels in preserving IF labeling signal. Surprisingly, we found the treatment of NaBH4 increased AF signal and enhanced the AF contrast of major autofluorescent structures. This finding suggests that NaBH4 has the potential to act as an AF enhancer and may facilitate the interpretation of myocardial structures without the need for counterstaining.

Introduction:

For cardiac arrest victims, providing high-quality cardiopulmonary resuscitation (CPR) is a fundamental component of initial care, especially in out-of-hospital settings. We sought to assess the knowledge of nonmedically trained individuals about CPR in case of cardiac arrest in the population of Jazan, Saudi Arabia.

Materials and Methods:

A cross-sectional survey containing 22 questions was administered to individuals aged ≥ 18 years who were not health-care providers. The sample comprised residents of Jazan, Saudi Arabia. The survey included knowledge about the signs of cardiac arrest, previous experiences with CPR, knowledge of basic life support (BLS), and concerns related to CPR.

Results:

This study examined responses from 480 people to assess their knowledge of CPR. More than one-half were female, and only 33% were male. Only 36.04% reported having received CPR training. In the event of a family member’s cardiac arrest, more than 90% state that they would perform CPR. If a family member suffered a sudden cardiac arrest, more than 70% would call an ambulance immediately, whereas only 48% would call an ambulance if the same thing happened to a stranger. Fear of making a mistake was the most common reason for not performing CPR (70.63%). The media was the most common source of CPR training. Women were more aware of the warning signs of sudden cardiac arrest than men. Women were also more likely than men to perform CPR or call for assistance. Furthermore, women were significantly more likely than men to discontinue CPR on a sudden cardiac arrest patient for fear of stopping a working heart or being contaminated by blood or vomit. Few respondents were willing to undergo CPR training; students, homemakers, and retired people were more willing to be trained in CPR than others.

Conclusion:

In the Saudi Arabian province of Jazan, nonmedically trained people demonstrated a low level of CPR training and knowledge. We believe that making BLS courses available to the general public will increase CPR awareness and understanding among adults and increase survival rates in cases of sudden cardiac arrest.

Published: October 2023

Atrial septal defect (ASD) is one of the most common congenital heart defects (3.78/10,000 live births). For several decades, surgical closure has been considered the standard method of repairing an ostium secundum ASD. Surgical treatment is safe and effective, but the complications relate to bleeding, arrhythmia, and residual defects. However, over the years, percutaneous device closure using the Amplatzer ASD occluder (AGA Medical Corp., Golden Valley, Minnesota) has been widely used for the treatment of ASD and has proven to be effective and safe as traditional surgical repair. However, procedure- or device-related complications can occur; Complications commonly associated with ASD closure device includes residual shunt, device malposition or embolization, thrombosis in the vena cava or atrium and erosion of the surrounding tissue which may lead to perforation of the heart, which could be fatal. We report an unusual case of a 16-year-old female with embolization of the ASD occluder device into the right ventricle immediately after device deployment. We removed the device surgically and closed the ASD in a standard manner, with an autologous pericardial patch. The patient was discharged from the hospital without any complications.
Dose-dependent Reduction of Blood Pressure by Angiotensin Receptor-neprilysin Inhibitor: A Network Meta-analysis
Authors: Kao Ting-Wei , Lee Yi-Chih
Published: October 2023

Context:

Angiotensin receptor-neprilysin inhibitor (ARNi) has been established as the standard medication for heart failure. However, the blood pressure (BP)-lowering effect circumvented its administration and titration in patients with borderline hypotension.

Aim:

This study aimed to determine the correlation between ARNi dosage and hemodynamic impacts.

Subjects and Methods:

A network meta-analysis was conducted to interrogate the BP impact of ARNi (sacubitril/valsartan 100 mg/d, 200 mg/d, 400 mg/d) and angiotensin receptor blocker (ARB) counterparts. Individuals with mild-to-moderate systolic hypertension were enrolled in respective studies. The outcomes were set as the change from baseline systolic and diastolic BP.

Statistical Analysis Used:

Network meta-analysis, node-splitting, and inconsistency model methods in Bayesian approach were employed.

Results:

A total of 14 manuscripts with 7705 subjects were included for pooled analysis. Compared with ARB, sacubitril/valsartan 400 mg/d and 200 mg/d, but not 100 mg/d, were associated with significantly greater reduction effect of systolic and diastolic BP, either by office documentation or 24-h ambulatory monitoring. The BP-lowering effect of sacubitril/valsartan 400 mg/d and 200 mg/d was nevertheless equivalent.

Conclusions:

ARNi exerts a dose-dependent effect on BP reduction. Such hemodynamic impact exceeds ARB at higher doses.

Published: October 2023

Background:

Prosthetic valve thrombosis is of the serious long-term complications of heart valve replacement that its treatment particularly in left-sided valves is controversial. Both surgery and thrombolysis are associated with their own merits and drawbacks. Hence, the aim of the present study is the evaluation of response to surgery and thrombolytic therapy in patients with aortic prosthetic valve thrombosis in a tertiary heart center in Tehran, Iran, during 2007–2019.

Materials and Methods:

In this retrospective study, 85 patients with aortic prosthetic valve thrombosis (including 63 case of surgery and 22 case of thrombolytic therapy) were evaluated. Response to clinical and hemodynamic treatment and frequency of complications and mortality were determined in each group.

Results:

Clinical complete response in surgery group (84.13%) was significantly more than patients with thrombolytic therapy (64.63%). The frequency of complications in surgery and the thrombolytic group was 12.7% and 9.09%, respectively, which show no significant difference. Mortality was seen in 1.58% and 4.53% of patients with surgery and thrombolytic therapy respectively that was not statistically significant. Complete failure of treatment was seen in 18.18% of patients with thrombolytic therapy and re-surgery was done for them. The surgery success rate was significantly more than thrombolytic success rate in patients with a therapeutic range of international normalized ratio (INR) level.

Conclusion:

Surgery versus thrombolytic therapy has more efficacy and similar safety in patients with aortic prosthetic valve thrombosis and may be preferable treatment for these patients. However, thrombolytic therapy also can be used as a suitable alternative, particularly in patients with a high risk of surgery.

The Coronavirus Disease 2019 (COVID-19) has rapidly spread globally, causing a significant impact on public health. This study proposes a predictive model employing machine learning techniques to distinguish between influenza-like illness and COVID-19 based on clinical symptoms and diagnostic parameters. Leveraging a dataset sourced from BMC Med Inform Decis Mak, comprising cases of influenza and COVID-19, we explore a diverse set of features, including clinical symptoms and blood assay parameters. Two prominent machine learning algorithms, XGBoost and Random Forest, are employed and compared for their predictive capabilities. The XGBoost model, in particular, demonstrates superior accuracy with an AUC under the ROC curve of 98.8%, showcasing its potential for clinical diagnosis, especially in settings with limited specialized testing equipment. Our model's practical applicability in community-based testing positions it as a valuable tool for efficient COVID-19 detection. This study advances the field of predictive modeling for disease detection, offering promising prospects for improved public health outcomes and pandemic response strategies. The model's reliability and effectiveness make it a valuable asset in the ongoing fight against the COVID-19 pandemic.
Two-well linearization for solid-solid phase transitions
Authors: Davoli Elisa , Friedrich Manuel
Published: October 2023

In this paper we consider nonlinearly elastic, frame-indifferent, and singularly perturbed two-well models for materials undergoing solid-solid phase transitions in any space dimensions, and we perform a simultaneous passage to sharp-interface and small-strain limits. Sequences of deformations with equibounded energies are decomposed via suitable Caccioppoli partitions into the sum of piecewise constant rigid movements and suitably rescaled displacements. These converge to limiting partitions, deformations, and displacements, respectively. Whereas limiting deformations are simple laminates whose gradients only attain two values, the limiting displacements belong to the class of special functions with bounded variation (
SBV
). The latter feature elastic contributions measuring the distance to simple laminates, as well as jumps associated to two consecutive phase transitions having vanishing distance, and thus undetected by the limiting deformations. By

\Gamma

- convergence we identify an effective limiting model given by the sum of a quadratic linearized elastic energy in terms of displacements along with two surface terms. The first one is proportional to the total length of interfaces created by jumps in the gradient of the limiting deformation. The second one is proportional to twice the total length of interfaces created by jumps in the limiting displacement, as well as by the boundaries of limiting partitions. A main tool of our analysis is a novel two-well rigidity estimate which has been derived in [Calc. Var. Partial Differential Equations 59, art. 44 (2020)] for a model with anisotropic second-order perturbation.
Classical and Quantized Maxwell Fields Deduced from Algebraic Many-Photon Theory
Authors: Rieckers Alfred
Published: October 2023

The deduction starts with the (non-relativistic) one-photon Hilbert space

\mathcal{H}

, equipped with the one-photon Hamiltonian and basic symmetry generators, as the only input information. We recall in the functorially associated boson Fock space the multi-photon dynamics and symmetry transformations, as well as the field operator (as the scaled self-adjoint part of the creation operator) and the q(uasi)-classical states. There is no reference to a presupposed classical Maxwell theory. By abstraction, we go over to the algebraic formulation of the multi-photon theory in terms of a C*-Weyl algebra. Its test function space

E\subset \mathcal{H}

is constructed as a nuclear Fréchet space, in which – via infrared damping – the dynamics and symmetries are nuclear continuous and their generators bounded. Each w*-closed, singular subspace of the continuous dual

E'

determines non-Fock coherent states and their mixtures lead to a representation von Neumann algebra with non-trivial center. The symmetry generators restricted to the center can be transformed into the Maxwell form by means of a symplectic transformation and involve the well-known conservation quantities of electrodynamics. This identifies the central part of the represented photon field operator as composed of the two classical canonical electrodynamic field components. We have obtained, therefore, in free space a kind of fusion of the multi-photon theory and the Maxwell theory of transverse electrodynamic fields, where the latter arise as derived quantities. By means of a Bogoliubov transformation one also gets a fusion of the quantized with the classical Maxwell theory, deduced from the photon concept. A sketch of non-relativistic gauging is added in the appendix to gain longitudinal, cohomological, and scalar potentials.
Full Justification for the Extended Green–Naghdi System for an Uneven Bottom with/without Surface Tension
Authors: Khorbatly Bashar , Israwi Samer
Published: October 2023

This paper is a continuation of a previous work on the extended Green–Naghdi system. We prolong the system, in arbitrary dimension, with/without surface tension, and for a general bottom topography. Confining the work to the one-dimensional case, wellposedness and consistency with respect to initial data and parameters are proved, taking into account the effect of surface tension. The results are local, but long term in the sense of dependence upon initial data. As a conclusion, our solution remains close to the exact solution of the full Euler system with a better (smaller) precision and therefore the full justification of the models.
$*$-logarithm for slice regular functions
Authors: Altavilla Amedeo , de Fabritiis Chiara
Published: October 2023

In this paper, we study the (possible) solutions of the equation

\exp_*(f)=g

, where

g

is a slice regular never vanishing function on a circular domain of the quaternions

\mathbb{H}

and

\exp_*

is the natural generalization of the usual exponential to the algebra of slice regular functions. Any function

f

which satisfies

\exp_*(f)=g

is called a

*

-logarithm of

g

. We provide necessary and sufficient conditions, expressed in terms of the zero set of the “vector” part

g_v

of

g

, for the existence of a

*

-logarithm of

g

, under a natural topological condition on the domain

\Omega

. By this way, we prove an existence result if

g_v

has no non-real isolated zeroes; we are also able to give a comprehensive approach to deal with more general cases. We are thus able to obtain an existence result when the non-real isolated zeroes of

g_v

are finite, the domain is either the unit ball, or

\mathbb{H}

, or

\mathbb{D}

(the solid torus obtained by circularization in

\mathbb{H}

of the disc contained in

\mathbb{C}

and centered in

2\sqrt{-1}

with radius

1

), and a further condition on the “real part”

g_0

of

g

is satisfied (see Theorem 6.19 for a precise statement). We also find some unexpected uniqueness results, again related to the zero set of

g_v

, in sharp contrast with the complex case. A number of examples are given throughout the paper in order to show the sharpness of the required conditions.

This integrated approach utilizing SolidWorks, ANSYS, and Design Expert holds promise for enhancing stent performance and optimizing patient outcomes.
Optimizing Reservoir Operation with Artificial Intelligence: A State of the Art Review
Authors: Astha Yadav
Published: October 2023

Reservoir operation is an important aspect of water resource management since it involves the prudent distribution of water for a variety of reasons such as water supply, irrigation, hydropower generation, flood control, and environmental preservation. Historically, reservoir operation has depended on heuristic and rule-based approaches, which frequently struggle to adapt to the dynamic and variable character of water arrangements. Artificial intelligence (AI) technologies have grown in popularity in recent years to increase reservoir operation efficiency and adaptability. This cutting-edge review investigates the use of AI in reservoir optimization. We offer a complete overview of several AI methods used in reservoir operations, such as machine learning (ML), reinforcement learning (RL), artificial neural networks (ANNs), fuzzy logic (FL), evolutionary algorithms (EA), optimization algorithms (OA), and hybrid models (HM). We analyze the advantages and limits of AI-driven reservoir operating models on their potential to optimize water resource management, alleviate climate change impacts, and improve reservoir system sustainability using a comprehensive review of the literature. This review paper aims to provide an overview of the current level of reservoir operation optimization with AI as well as insights into future approaches. As the globe faces increasing difficulties related to water scarcity, climate unpredictability, and environmental protection, utilizing the potential of artificial intelligence in reservoir operation becomes critical for building efficient, adaptive, and sustainable water management approaches.
