Correlated fission fragment angular momenta
Authors: Randrup Jørgen
Published: March 2024

Nuclear fission produces fragments whose spins are coupled to each other as well as to the relative fragment motion due to angular momentum conservation. Statistical ensembles of such spins can readily be obtained by either direct microcanonical sampling or by sampling of the associated normal modes of rotation. The spin-spin opening angle distribution is illustrated for both 3D and 2D spin scenarios and it is demonstrated how recent calculations with various models can be well reproduced by the statistical results under different assumptions about the scission geometry.

Duality analysis of interior penalty discontinuous Galerkin methods under minimal regularity and application to the a priori and a posteriori error analysis of Helmholtz problems
Authors: Chaumont-Frelet Théophile
Published: March 2024

We consider interior penalty discontinuous Galerkin discretizations of time-harmonic wave propagation problems modeled by the Helmholtz equation, and derive novel a priori and a posteriori estimates. Our analysis classically relies on duality arguments of Aubin–Nitsche type, and its originality is that it applies under minimal regularity assumptions. The estimates we obtain directly generalize known results for conforming discretizations, namely that the discrete solution is optimal in a suitable energy norm and that the error can be explicitly controlled by a posteriori estimators, provided the mesh is sufficiently fine.
A Review of the Current Status of AI Research in Handwritten Chinese Character Recognition
Authors: Ye-eun Kim
Published: March 2024

With the continuous development of artificial intelligence technology, there have been attempts to utilize AI in the field of linguistics. In this context, research and development in AI-based Chinese character recognition technology has spanned 40 years, with its outcomes attracting significant attention. However, in the field of Chinese character recognition, the research into offline handwritten recognition technology is particularly challenging due to the unique characteristics of handwritten Chinese characters. The main issue in current research is the significant decrease in accuracy for characters composed of similar components or characters with similar overall shapes. The focus of research solutions has been on modern mechanical programming and other engineering aspects, while research that integrates the inherent characteristics of Chinese characters themselves has been relatively overlooked. The author believes that combining engineering technology research with a deeper understanding of the nature of Chinese characters can solve many of the current problems. This paper reviews the current state of related domestic and international research to identify areas with significant potential for improvement and progress in research, and finally proposes directions for future research.

An Empirical Study on Cultural Image, Perceived Value, and Purchase Intention: A Case of Chinese Intangible Cultural Heritage “Gambiered Canton Gauze”
Authors: Chan Delphine Yachu , Pan Zicheng
Published: March 2024

Gambiered Canton gauze is a unique double-sided silk product in Guangdong Province, China, securing its status as one of the national intangible cultural heritages (ICH) due to its exceptional yarn finishing techniques. Despite the implementation of China’s rural revitalization policy, gambiered Canton gauze did not seize the opportunity to enhance its live transmission. Instead, it encountered a small consumer market because of its high prices and weak publicity. To better inherit and promote ICH products, this study explores the relationship between their cultural images, perceived values, and purchase intention from the perspective of cultural values. The results demonstrate that the cultural images of ICH products, such as practical reason, nostalgic inheritance, and face images, exert a significantly positive impact on purchase intention. Notably, the face images conveyed by ICH products are the key factor affecting the purchase intention. In the above relationship, functional values and social values serve as intermediary factors.

Authors: Meindl Eva , Gisinger Martin , Kitchen Maria , Türtscher Luca , Ratzinger Gudrun , Schmuth Matthias , Sarcletti Mario
Published: March 2024

Ziel Wir berichten von den Affenpocken (Mpox)-Fällen, die mittels Affenpockenvirus (MPXV)-Polymerase-Kettenreaktion (PCR) bestätigt und an der Universitätsklinik für Dermatologie, Venerologie und Allergologie Innsbruck zwischen Mai und August 2022 behandelt wurden.

Methode Es wurden klinische Präsentationen aller Patienten dokumentiert und die Ergebnisse mit anderen Publikationen verglichen.

Ergebnisse Insgesamt wurden 17 Patienten mit einer MPXV vorstellig. Es handelte sich hierbei ausschließlich um Männer, die mit Männern Sex hatten. Das mediane Alter bei Bestätigung der Infektion betrug 35 Jahre. 100% der Patienten litten an Allgemeinsymptomen und 94% entwickelten im Verlauf Hautläsionen. Eine Übertragung der Infektion erfolgte in den allermeisten Fällen durch engen Körperkontakt. Bei 18% der beschriebenen Patienten kam es zu einer Koinfektion mit einer sexuell übertragbaren Erkrankung. 35% hatten in den letzten 6 Wochen vor dem positiven MPXV PCR-Test eine Syphilis-, Chlamydien- oder Gonokokkeninfektion. Bei 23% der Patienten war eine HIV- Infektion bekannt und 53% nahmen zum Zeitpunkt der Infektion eine HIV-Präexpositionsprophylaxe (PrEP).

Schlussfolgerung Wir können in dieser Arbeit aufzeigen, dass trotz des kleinen Patientenkollektivs die Daten der beschriebenen Patienten sehr gut mit größeren Studien vergleichbar sind. Entgegen der bisher bekannten Tier-zu-Mensch-Übertragung des endemisch in Afrika auftretenden Orthopox-Virus Typ MPXV kam es im weltweiten Ausbruch 2022 hauptsächlich zu Übertragungen durch sexuellen Kontakt zwischen Menschen. Somit ist ein zusätzliches Screening auf andere sexuell übertragbare Erkrankungen bei Patienten mit einer MPXV unumgänglich.
Chemoembolization Beyond Hepatocellular Carcinoma: What Tumors Can We Treat and When?
Authors: DePietro Daniel M. , Li Xin , Shamimi-Noori Susan M.
Published: March 2024

Liver metastases are the most common malignancy found in the liver and are 20 to 40 times more common than primary hepatic tumors, including hepatocellular carcinoma. Patients with liver metastases often present with advanced disease and are not eligible for curative-intent surgery or ablative techniques. The unique hepatic arterial blood supply of liver metastases allows interventional radiologists to target these tumors with transarterial therapies. Transarterial chemoembolization (TACE) has been studied in the treatment of liver metastases originating from a variety of primary malignancies and has demonstrated benefits in terms of hepatic progression-free survival, overall survival, and symptomatic relief, among other benefits. Depending on the primary tumor from which they originate, liver metastases may have different indications for TACE, may utilize different TACE regimens and techniques, and may result in different post-procedural outcomes. This review offers an overview of TACE techniques and specific considerations in the treatment of liver metastases, provides an in-depth review of TACE in the treatment of liver metastases originating from colorectal cancer, neuroendocrine tumor, and uveal melanoma, which represent some of the many tumors beyond hepatocellular carcinoma that can be treated by TACE, and summarizes data regarding when one should consider TACE in their treatment algorithms.
Intra-arterial Peptide Receptor Radionuclide Therapy for the Treatment of Hepatic Neuroendocrine Tumor Metastases: Hope or Hype?
Authors: Khanjyan Michael V. , Fidelman Nicholas
Published: March 2024

Peptide receptor radionuclide therapy (PRRT) confers significant progression-free survival advantage for patients with small bowel grade 1 and 2 well-differentiated neuroendocrine tumors (WD NET). PRRT may also be clinically beneficial for patients with NET of pancreatic, bronchial, and other sites of origin; patients with paragangliomas; as well as for patients with well-differentiated grade 3 NET. Direct intra-arterial (IA) administration of PRRT into the hepatic artery for patients with NET liver metastases may result in higher radiopharmaceutical dose and longer dwell time in the liver tumors while relatively sparing non-tumor liver tissue and other organs such as the kidneys and bone marrow when compared with intravenous (IV) administration. This review summarizes currently available data on IA and IV PRRT dose distribution, reports safety and efficacy of IA PRRT, and proposes future research questions.
“Different names for the same thing”? Novelty, expectations, and performative nominalism in personalized and precision medicine
Authors: Galasso Ilaria , Erikainen Sone , Pickersgill Martyn , Testa Giuseppe
Published: March 2024

This paper explores the complementary and contrasting uses of the terms ‘personalized medicine’ and ‘precision medicine’ in denotations of a biomedical approach attentive to individual specificities that harnesses genomics and other data-intensive profiling technologies. Drawing on qualitative interviews conducted with biomedical experts in the context of the Precision Medicine Initiative in the United States and the 100,000 Genomes project in the United Kingdom, we read definitional reflection and debate through the lens of the sociologies of expectations and novelty. We observed two key aspects in the shift from ‘personalized medicine’ to ‘precision medicine’ that has been especially prevalent in the United States. First, the term ‘precision medicine’ enables its proponents to rhetorically depart from the idea that this approach to medicine can be expected to deliver individually personalized treatments—an expectation that is seen as unrealistic by many. Second, it enables its proponents to assert that personalization, when understood as caring about the patient as an individual person, is not a new approach to medicine but rather something that many medical professionals have always aimed to do (eliding in the process other experiences of US healthcare as, for instance, alienating and discriminatory). We argue that the shift from ‘personalized’ to ‘precision’ medicine can be regarded as a manifestation of performative nominalism: an attribution of ‘newness’ that contributes to performing and propelling innovation, rather than solely reflecting it. In so doing, rhetorical demarcations between personalized and precision medicine emerge as performatively contributing to the production of different biomedical ontologies.

Authors: Su Yiqing , Zhang Shifei , Li Yanyan , Yu Hailong
Published: March 2024

Consumer participation is critical to achieving successful food safety governance. However, in the field of food safety governance, consumer participation faces the dilemma of collective action. Based on social capital theory, this study introduces a total of 1229 questionnaires from online food consumers in China were collected by randomly distributing electronic questionnaires to online shoppers, and tests the effect and mechanism of social capital on consumer participation in food safety governance. By using ordered regression and multinomial logit models, the empirical results show that social capital can reduce the adverse effects of free-riding on consumers’ participation in food safety governance and in fact will ultimately encourage consumers to participate in food safety governance. Furthermore, social capital will enhance people’s participation in food safety governance through two paths: promoting consumers’ sharing of food safety information and promoting consumers’ direct supply of safe food. The conclusion of this paper provides inspiration for the promotion of consumer participation in the public affairs related to food safety governance in developing countries.

Authors: Tantlevskij Igor R. , Evmenova Elizaveta , Gromov Dmitry
Published: March 2024

In this paper, we apply the methods of graph theory to reveal hidden relations within the corpus of the Hebrew Bible texts. The structure of relations between different texts was studied based upon their interpretation of the otherworld and the afterlife. We have identified 43 most relevant texts that contained concepts related to the notion of the otherworld and constructed a graph representing the relations between the considered texts. The obtained graph was decomposed into 3 densely connected subgraphs using the Louvain method. An initial interpretation has been given to the results of the decomposition. Furthermore, we used different ranking methods to determine the most important texts forming the network structure of the intertextual connections. It turned out that there is an invariant set of texts that can be interpreted as having the larger influence or importance on the development of the idea of the otherworld. These texts are Proto-Isaiah, Qoheleth, Job, Psalms, and Proverbs as well as 1 Samuel, Ezekiel, and Book of Genesis. Furthermore, a detailed analysis of the notions, associated with these texts, reveals that there are several concepts that are likely to be associated with the most influential texts.

Authors: Cao Shenyang , Dong Tienan , Cao Yichen , Lei Jiabao , Zhang Siyi , Hang Zusheng , Huang Yu’an
Published: March 2024

The development and characterization of sulfonated melamine formaldehyde resin microspheres (SMF microspheres) as light diffusers in epoxy resin was presented in this paper. The SMF microspheres were prepared through dispersion polymerization with uniform particle size, smooth surface, and a high refractive index. The particle size of the microspheres was controllable within the range from 0.8 to 3.7 µm according to the pH during acidic condensation and the amount of melamine. Compared to traditional MF microspheres, SMF microspheres possessed unique sulfonic acid groups, higher primary amine content, and stronger polarity, which prevent agglomeration when mixed with epoxy resin. The SMF microspheres thus prepared were used as light-diffusing fillers with epoxy resin as matrix. Experimental results and single-particle Mie scattering simulations confirmed that SMF microspheres with a higher refractive index and smaller particle size exhibited higher light-shading efficiency and the haze of EP, demonstrating their outstanding light-diffusing performance. In summary, the significant potential application of SMF microspheres in the field of light diffusers was demonstrated.

Published: March 2024

To enhance my research, I would like to share my knowledge of Herpes simplex virus-2 (HSV-2) and HIV/AIDS (Acquired Immunodeficiency Syndrome) through a mathematical model. The study’s objective is to develop and examine the co-disease model for the modern era using mathematical modeling. Based on their modes of transmission, HSV-2 and HIV/AIDS are currently the leading causes of death from infectious and severe chronic diseases. Depending on the severity of HIV-2’s chronic disease, the model is divided into five phases: the first two HIV-2 stages and the remaining three HIV stages. Ordinary differential equations (ODEs) are arranged differently by each individual. Investigations into the mathematical equation model have revealed the points of equilibrium between the free and endemic models. A study of the developed model was conducted using the basic reproduction numbers [R0] of HSV-2 and HIV. The results demonstrate that if R0<1, the free equilibrium of disease is asymptotically locally stable. When R0>1, equilibrium endemic states are regarded as existing. Finally, MATLAB software was used to simulate the numerical equations of the model.
The Laplacian spectrum of weighted composite networks and the applications
Authors: Zhu Jian , Huang Da , Gao Haiping , Li Xianyong
Published: March 2024

The topological properties of the networks can be described by the Laplacian spectra, but resolving the Laplacian spectra of networks poses difficulties. In this study, a novel approach for solving the Laplacian spectrum of weighted composite networks is presented. We first give the definitions of three weighted graph operations, namely, Cartesian product, corona, and join. Second, the Laplacian spectra of these composite networks are calculated. Finally, we use the obtained Laplacian spectrum to deduce some topological properties of the networks, such as network coherence, entire mean first-passage time, and Laplacian energy, which have several applications in physical chemistry.
Correlation between PPF index and short-term memory in physical-reservoir computing with artificial synapse using simple RC-series circuit
Authors: Komatsu Hiroaki , Ogawa Takumi , Hosoda Norika , Ikuno Takashi
Published: March 2024

The correlation between the short-term plasticity (STP) of artificial synapses and the computational performance of physical-reservoir computing (PRC) using artificial synapses has not yet been clarified. We investigate the correlation between the paired-pulse facilitation (PPF) index, which is an evaluation indicator of STP, and the memory capacity (MC) of the short-term memory task, which is one of the computational performance indicators of PRC, using a simple artificial synapse based on a series circuit comprising a resistor and a capacitor. The results show that a higher PPF index of the artificial synapse does not necessarily indicate a higher MC of the PRC using that artificial synapse. The maximum MC is obtained when the time constant of the artificial synapse and the pulse width of the input pulse are comparable. Typically, the MC is found to be the maximum at a PPF index of 114%. This correlation provides valuable guidelines for the design of artificial synapses for PRC applications, as the performance of PRC can be predicted from the STP parameters of artificial synapses.

Published: March 2024

Objectives Unwarranted clinical variations in radical prostatectomy (RP) procedures are frequently reported, yet less attention is given to the variations in associated costs. This issue can further widen disparities in access to care and provoke questions about the overall value of the procedure. The present paper aimed to delve into the disparities in hospital, medical provider and out-of-pocket costs for RP procedures in Australia, discussing plausible causes and potential policy opportunities. Methods A retrospective cohort study using Medibank Private claims data for RP procedures conducted in Australian hospitals between 1 January 2015 and 31 December 2020 was undertaken. Results Considerable variations in both medical provider and out-of-pocket costs were observed across the country, with variations evident between different states or territories. Particularly striking were the discrepancies in the costs charged by medical providers, with a notable contrast between the 10th and 90th percentiles revealing a substantial difference of A$9925. Hospitals in Australia exhibited relatively comparable charges for RP procedures. Conclusions Initiatives such as enhancing transparency regarding individual medical provider costs and implementing fee regulations with healthcare providers may be useful in curbing the variations in RP procedure costs.
Untargeted metabolomic analysis of the metabolites in roots of Pugionium cornutum seedlings under drought stress
Authors: Wu Zhaoxin , Wang Ping , Chen Guihua
Published: March 2024

Pugionium cornutum is an annual or biennial xerophyte distributed in arid regions, with drought resistance properties. While previous studies have predominantly focused on the physiological changes of P. cornutum, the understanding of its metabolite variations remains limited. In this study, untargeted metabolomic technology was performed to analyse the change of metabolites in the roots of P. cornutum seedlings under drought stress. Our findings revealed that compared to the R1, the root water potential and the number of lateral roots increased, while the length of the tap root and fresh weight increased first and then decreased. In the R1–R2, a total of 45 differential metabolites (DMs) were identified, whereas in the R1–R3 82 DMs were observed. Subsequently, KEGG analysis revealed a significant enrichment of microbial metabolism in diverse environments and aminobenzoate degradation in the R1–R2, and phenylpropanoid biosynthesis, ubiquinone, and other terpenoid-quinone biosynthesis and isoquinoline alkaloid biosynthesis were significantly enriched in the R1–R3. The upregulation DMs, including L-arginosuccinate, L-tyrosine, p-coumarate, caffeate, ferulate, vanillin, coniferin, 5-aminopentanoate, 2-methylmaleate and 2-furoate in P. cornutum seedlings may play a crucial role in enhancing root growth and improving drought resistance. These findings provide a basis for future investigations into the underlying mechanisms of drought resistance in P. cornutum.

Published: March 2024

Human cytomegalovirus (HCMV) infection of monocytes is essential for viral dissemination and persistence. We previously identified that HCMV entry/internalization and subsequent productive infection of this clinically relevant cell type is distinct when compared to other infected cells. We showed that internalization and productive infection required activation of epidermal growth factor receptor (EGFR) and integrin/c-Src, via binding of viral glycoprotein B to EGFR, and the pentamer complex to β1/β3 integrins. To understand how virus attachment drives entry, we compared infection of monocytes with viruses containing the pentamer vs. those without the pentamer and then used a phosphoproteomic screen to identify potential phosphorylated proteins that influence HCMV entry and trafficking. The screen revealed that the most prominent pentamer-biased phosphorylated protein was the lipid- and protein-phosphatase phosphatase and tensin homolog (PTEN). PTEN knockdown with siRNA or PTEN inhibition with a PTEN inhibitor decreased pentamer-mediated HCMV entry, without affecting trimer-mediated entry. Inhibition of PTEN activity affected lipid metabolism and interfered with the onset of the endocytic processes required for HCMV entry. PTEN inactivation was sufficient to rescue pentamer-null HCMV from lysosomal degradation. We next examined dephosphorylation of a PTEN substrate Rab7, a regulator of endosomal maturation. Inhibition of PTEN activity prevented dephosphorylation of Rab7. Phosphorylated Rab7, in turn, blocked early endosome to late endosome maturation and promoted nuclear localization of the virus and productive infection.

Published: March 2024

An effective approach to high-sensitivity magnetic field detection under low-frequency excitation by soft magnetic ribbons and a rectangular solenoid is proposed and certificated. The solenoid wound by nonmagnetic copper wire is located at the geometric center region of the soft magnetic ribbons that act as the magnetic core. The proposed magnetic sensor utilizes the nonlinear magnetization of soft magnetic ribbons and the magneto-inductive effect and proximity effect of the solenoid, exhibiting significant impedance variation at a relatively low frequency. The impedance ratio and impedance sensitivity of the prototype reaches the maximum value of 5630% and 570% Oe−1 at 500 kHz, which is far superior to the conventional giant magneto-impedance (GMI) magnetic sensor and planar coil laminated GMI magnetic sensor. The investigation indicates the fabricated magnetic sensor with optimal dimension parameters can provide a sensitivity of 3329 mV Oe−1 at 500 kHz. More importantly, the proposed prototype is particularly suitable for micromachining, providing the possibility for manufacturing high-sensitivity micro-magnetic sensors.

. We identify the lowest lying state as being a 1s state, consistent with the well known Δ(1232). The first excitation is identified as a 2s state, but is found to have a mass of approximately 2.15 GeV on our ∼3 fm lattice, which does not appear to be associated with the Δ(1600) resonance in a significant manner. We also report on the spin-1/2 and odd-parity states accessible via our methods. The large excitation energies of the radial excitations provide a potential resolution to the long-standing missing baryon resonances problem.

In recent years, the rapid development of smart wearable devices has resulted in significant advances in flexible pressure sensors, which have found application in speech recognition, health monitoring, as well as motion tracking. There is, however, still a significant challenge associated with the low-cost preparation of flexible pressure sensors with high sensitivity and permeability. An innovative nonwoven-based flexible pressure sensor is presented in this paper consisting of a conductive sensing layer composed of reduced graphene oxide-treated polyester hydrophilic nonwoven, an electrode layer comprised of carbon nanotube-printed polyester plain nonwoven electrodes, and a top pressure layer composed of hydroentangled viscose dome structure nonwoven. The pressure sensor exhibits high sensitivity (5.43% kPa−1 in the range of 0–10.12 kPa), excellent permeability (807.2 mm s−1), rapid response and recovery time (73/73 ms), a wide sensing range (0–185 kPa), and remarkable cycling durability (∼20,000 cycles). The sensor exhibits superhydrophobic properties, as indicated by a water contact angle of up to 155°. Based on its commendable performance, the sensor demonstrates the capability to discern various pressure signals, enabling the potential for encrypted transmission of military information. Additionally, it proves valuable in applications such as health monitoring and motion tracking. Consequently, the flexible pressure sensor has significant potential for application in areas such as data encryption, health monitoring, and motion detection.
Matter waves and clocks do not observe uniform gravitational fields

In a uniform gravitational field, classical test objects fall universally. Any reference object or observer will fall in the same universal manner. Therefore, a uniform gravitational field cannot create dynamics between observers and classical test objects. The influence of a uniform gravitational field on matter waves and clocks, however, is described inconsistently throughout research and education. To illustrate, we discuss the behavior of a matter-wave interferometer and a clock redshift experiment in a uniform gravitational field. As a consistent formulation of the equivalence principle implies, a uniform gravitational field has no observable influence on these systems and is physically equivalent to the absence of gravity.
The multiplayer generalizations of Frackiewicz and Li-Du-Massar quantum schemes
Authors: Wang Nengfa , Yang Zhe
Published: March 2024

Drawing inspiration from the Frackiewicz and Li-Du-Massar quantum schemes, we provide some multiplayer generalizations of their techniques. Initially, we introduce a multiplayer version of the Frackiewicz quantum scheme, and give quantum Cournot oligopoly games with both three and n players. Our findings indicate that quantum equilibrium profits decrease monotonically with increasing entanglement levels of environments participated by oneself, but increase monotonically with the entanglement levels of other players. Subsequently, we present a multiplayer extension of the Li-Du-Massar quantum scheme, and analyze quantum Cournot oligopoly games with three and n players. We observe that quantum equilibrium profit exhibits a positive correlation with entanglement levels. Furthermore, the quantum equilibrium quantity and profit exhibit a negative correlation with the number of players for both multiplayer quantum schemes.
WIMP constraints from black hole low-mass X-ray binaries

The abnormally fast orbital decay observed in the black hole (BH) Low-Mass X-ray
binaries (BH-LMXB) A0620-00 and XTE J1118+480 can be explained by the dynamical friction between
Dark Matter (DM) and the companion star orbiting around the low-mass BH (≃ a few M
⊙) of the system. In this case the value of the index γ
sp of the DM spike
surrounding the BH can be pinned down with an accuracy of ≃ a few percent, way better than
that for much bigger systems such as the super massive BHs (SMBHs) in the Galactic Center or in
M87. We have used data from XTE J1118+480 to put bounds on the WIMP annihilation cross section
times velocity ⟨σv⟩, assuming that DM annihilation is driven by the χχ → bb̅ annihilation channel and that it proceeds in s-wave. The bounds
are driven by the radio synchrotron signal produced by e
± final states propagating in the
magnetic field in the vicinity of the BH. We find that for DM masses m
χ up to the TeV scale
XTE J1118+480 allows to constrain ⟨σv⟩ well below the standard value ⟨σv⟩thermal, corresponding to the observed DM relic density in the
Universe for a thermal WIMP. On the other hand, for m
χ ≳ 15 GeV, the bounds from the
SMBHs in the GC or in M87 do not reach ⟨σv⟩thermal when the very large
uncertainties on the corresponding spike indices are taken into account, in spite of potentially
producing much larger DM densities compared to XTE J1118+480. Our bounds for XTE J1118+480 have a
mild sensitivity on the effect of spatial diffusion (which implies at most a weakening of the
bounds of a factor ≲ 6 at large m
χ). However, diffusion is instrumental in
enhancing the sensitivity of the results upon the intensity of the magnetic field. In particular,
our bounds rest on the assumption that the magnetic field B reaches the equipartition value B
eq. We find that a reduction factor of the magnetic field B
eq/B larger than
about 14 at low m
χ, becoming progressively smaller at higher WIMP masses, would be
sufficient to relax the XTE J1118+480 bound to the level of other existing bounds. Recent
estimates, albeit not conclusive, may suggest values of B
eq/B in BH-LMXB systems as
large as 20. This implies that the intensity of the magnetic field in BH-LMXB systems represents
the major uncertainty in using them as an alternative to heavier BHs to search for WIMPs.
Limits on clustering and smooth quintessence from the EFTofLSS
Authors: D'Amico Guido , Donath Yaniv , Senatore Leonardo , Zhang Pierre
Published: March 2024

We apply the Effective Field Theory of Large-Scale Structure (EFTofLSS) to analyze
cosmological models with clustering quintessence, which allows us to consistently describe the
parameter region in which the quintessence equation of state w < -1. First, we extend the
description of biased tracers in redshift space to the presence of clustering quintessence, and
compute the one-loop power spectrum. We solve the EFTofLSS equations using the exact time
dependence, which is relevant to obtain unbiased constraints. Then, fitting the full shape of BOSS
pre-reconstructed power spectrum measurements, the BOSS post-reconstruction BAO measurements, BAO
measurements from 6DF/MGS and eBOSS, the Supernovae from Pantheon, and a prior from BBN, we bound
the clustering quintessence equation of state parameter w = -1.011-0.048
+0.053 at 68%
C.L. Further combining with Planck, we obtain w = -1.028-0.030
+0.037 at 68% C.L. We
also obtain constraints on smooth quintessence, in the physical regime w ≥ -1: combining all
datasets, we get -1 ≤ w < -0.979 at 68% C.L. These results strongly support a cosmological constant.
Electrodynamics with violations of Lorentz and U(1) gauge symmetries and their Hamiltonian structures*

Published: March 2024

This study aims to investigate Lorentz/U(1) gauge symmetry-breaking electrodynamics in the framework of the standard-model extension and analyze the Hamiltonian structure for the theory with a specific dimension

of Lorentz breaking operators. For this purpose, we consider a general quadratic action of the modified electrodynamics with Lorentz/gauge-breaking operators and calculate the number of independent components of the operators at different dimensions in gauge invariance and breaking. With this general action, we then analyze how Lorentz/gauge symmetry-breaking can change the Hamiltonian structure of the theories by considering Lorentz/gauge-breaking operators with dimension

as examples. We show that the Lorentz-breaking operators with gauge invariance do not change the classes of the theory constrains and the number of physical degrees of freedom of the standard Maxwell electrodynamics. When U(1) gauge symmetry-breaking operators are present, the theories generally lack a first-class constraint and have one additional physical degree of freedom compared to the standard Maxwell electrodynamics.
