description: We study the complete one loop contribution to $H^\pm\to W^\pm V$, $V= Z, γ$, in the Minimal Supersymmetric Standard Model (MSSM). We evaluate the MSSM contributions taking into account $B\to X_sγ$ constraint as well as experimental constraints on the MSSM parameters. In the MSSM, we found that in the intermediate range of $\tanβ\la 10$ and for large $A_t$ and large $μ$, where lightest stop becomes very light and hence squarks contribution is not decoupling, the branching ratio of $H^\pm \to W^{\pm} Z$ can be of the order $10^{-3}$ while the branching ratio of $H^\pm \to W^{\pm} γ$ is of the order $10^{-5}$. We also study the effects of the CP violating phases of Soft SUSY parameters and found that they can modify the branching ratio by about one order of magnitude.

Riforma e agire sociale della chiesa: rivendicare e dialogare da credenti nel cambiamento d'epoca
Creators: name: Girardi, Vito Antonio
Publisher: name: Apulia Theologica
Year: 2025

description: Nel cambiamento d'epoca che stiamo vivendo, cosa chiede Dio alla chiesa rispetto al suo agire sociale? Come spiega Caritas in veritate 56, da fine Ottocento è stata messa in campo un'azione di rivendicazione dello statuto di cittadinanza della religione cristiana nella sfera pubblica: è nata così la dottrina sociale della chiesa. Con il concilio Vaticano II l'azione privilegiata è stato il dialogo, come descritto da Ecclesiam suam. Sia l'azione di rivendicazione che l'azione di dialogo andranno condotte oggi da credenti, ovvero evitando di assecondare la logica mondana della valutazione, tipica del nichilismo. Essa si fonda su un'insicurezza affettiva ed esistenziale, che ha plasmato il sociale nella forma di una società sistemica. Il cristiano può farsene carico solo con la radicalità della follia della croce.

description: We report on resistivity and Hall measurements in thin films of the electron-doped superconducting cuprate Pr$_{2-x}$Ce$_{x}$CuO$_{4\pmδ}$. Comparisons between x = 0.17 samples subjected to either ion-irradiation or oxygenation demonstrate that changing the oxygen content has two separable effects: 1) a doping effect similar to that of cerium, and 2) a disorder effect. These results are consistent with prior speculations that apical oxygen removal is necessary to achieve superconductivity in this compound.

description: Abstract

A thriving society requires favorable environmental conditions, safe drinking water, and adequate sanitation and hygiene. The current generation finds itself amidst challenging environmental circumstances, both within and outside schools, negatively impacting the physical and mental well-being of students. The research aims to enhance the environmental education capacity of school teachers to promote environmental protection and address climate change. Separate four-day training sessions were conducted for public and private school teachers, randomly selected from the pool of science teachers. Pre- and post-study assessments were administered to measure the knowledge gain, serving as a predictor for the immediate outcomes of the study. The participants in the training sessions exhibited an average knowledge improvement of 54%. As indirect beneficiaries, the project is anticipated to positively impact 13,269 students and 598 teachers. It is expected to aid policymakers in integrating environmental and health considerations into policy formulation.

description: Recently it has been shown that ac-driven double quantum dots can act as spin pumps and spin filters. By calculating the current through the system for each spin polarization, by means of the time evolution of the reduced density matrix in the sequential tunneling regime (Born-Markov approximation), we demonstrate that the spin polarization of the current can be controlled by tuning the parameters (amplitude and frequency) of the ac field. Importantly, the pumped current as a function of the applied frequency presents a series of peaks which are uniquely associated with a definite spin polarization. We discuss how excited states participating in the current allow the system to behave as a bipolar spin filter by tuning the ac frequency and intensity. We also discuss spin relaxation and decoherence effects in the pumped current and show that measuring the width of the current vs frequency peaks allows to determine the spin decoherence time $T_{2}$.

Year: 2020
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Domain adaptive person Re-Identification (ReID) is challenging owing to the domain gap and shortage of annotations on target scenarios. To handle those two challenges, this paper proposes a coupling optimization method including the Domain-Invariant Mapping (DIM) method and the Global-Local distance Optimization (GLO), respectively. Different from previous methods that transfer knowledge in two stages, the DIM achieves a more efficient one-stage knowledge transfer by mapping images in labeled and unlabeled datasets to a shared feature space. GLO is designed to train the ReID model with unsupervised setting on the target domain. Instead of relying on existing optimization strategies designed for supervised training, GLO involves more images in distance optimization, and achieves better robustness to noisy label prediction. GLO also integrates distance optimizations in both the global dataset and local training batch, thus exhibits better training efficiency. Extensive experiments on three large-scale datasets, i.e., Market-1501, DukeMTMC-reID, and MSMT17, show that our coupling optimization outperforms state-of-the-art methods by a large margin. Our method also works well in unsupervised training, and even outperforms several recent domain adaptive methods.

description: In this thesis, numerical optimization is studied. Optimization is seeking for solution(s) taken from a set of admissible or feasible solutions that minimize (or maximize) a performance measure or objective. Optimization is a very powerful concept. Many problems in different fields can be casted as optimization problems. In this thesis, crossreading of numerical optimization and adaptive signal processing is attempting. Adaptive filters with varying step size are deployed for echo cancellation and system identification. In Chapter 1, an introduction in numerical optimization is made. In Chapter 2, we present optimization algorithms without constraints. The next two chapters are devoted to line search methods and trust region methods, respectively. Discussion on Least Mean Squares (LMS) algorithm follows. Then, a method is presented for step size selection that yields a faster convergence. Comparisons with step-size selection techniques from numerical optimization (e.g. Armijo rules) are made. Finally, fast affine projection algorithms using Armijo rules are derived.

description: We consider trapped bosons with contact interactions as well as Coulomb repulsion or gravitational attraction in one spatial dimension. The exact ground state energy and wave function are identified in closed form together with a rich phase diagram, unveiled by Monte Carlo methods, with crossovers between different regimes. A trapped McGuire quantum soliton describes the attractive case. Weak repulsion results in an incompressible Laughlin-like fluid with flat density, well reproduced by a Gross-Pitaevskii equation with long-range interactions. Higher repulsion induces Friedel oscillation and the eventual formation of a Wigner crystal.

The conundrum of Japan’s modernization: an examination of enlightenment prints of the 1870’s
Creators: name: Lo, Teresa Wing-Yan
Publisher: name: University of British Columbia
Year: 2009

description: The subject of investigation is a specific genre of Meiji period (1868-1912) woodblock prints known as Enlightenment prints (kaika nishiki-e), produced in Tokyo during the 1870s. While working with the technique and style of the previous century, they exploit themes of modernization and Westernization. An astounding volume of prints appeared during this period, with popular demand and technical facility higher than ever before. Curiously, these works have not been treated critically by scholars, who see them as amusing oddities marred by bright aniline colors. Art historians have focused on artists such as Tsukioka Yoshitoshi (1839-1892) and Kobayashi Kiyochika (1847-1915) who reinterpreted themes from classical literature and ukiyo-e* prints and paintings, or who experimented with Western innovations such as volumetric modeling and defined sources of light. Enlightenment prints, on the other hand, are visual documents of a rapidly changing Japan. Their significance can be appreciated, if they are studied in the proper cultural context, for their development closely parallels the aspirations of the citizens and policies of the Meiji oligarchy, which was primarily to regain equal status through revisions of the unequal treaties imposed by the foreign powers in the 1850s. Characteristic of Enlightenment prints of the 1870s are Ginza street scenes. The emphasis is on new inner-city transportation, new utilities, and new buildings. The bustle of street traffic and trains reflects the quickened pace of life, and progress. The triptych format favored by artists in the Meiji period lends itself to elaborating the horizontal expanse of a new bridge or the breadth of a spacious boulevard. Cityscapes by Hiroshige III, Kuniteru II and others convey quite literally the broad new horizons and exhilarating scale of Meiji Japan. More than simple street scenes, these images emphasize the national mobilization towards modernization that typified the decade of the 1870s, the motivation being the desire to attain equality with the West. The excitement of Western influences and the juxtaposition of such influences in scenes they were familiar with attracted a large public for the Enlightenment prints. In this thesis, I will explore the scenes the Enlightenment prints promoted, the point of views reflected. Their subject matter mirrors the view that modernization is positive and admirable. However, by analyzing the social mores and print culture of the 1870s, I will argue that there is more than meets the eye in the Enlightenment prints. Contemporary accounts of the massive changes in this decade reveal the fact that rapid modernization is a continuous struggle. It is my contention that in the early years of this period, disparate images produced in the prints reveal the urban, economic and social complexities of the modernization process.
Efficient sliding locomotion of three-link bodies

description: We study the efficiency of sliding locomotion for three-link bodies in the presence of dry (Coulomb) friction. Friction coefficient space can be partitioned into several regions, each with distinct types of efficient kinematics. These include kinematics resembling lateral undulation with very anisotropic friction, small-amplitude reciprocal kinematics, very large amplitude kinematics near isotropic friction, and kinematics that are very asymmetric about the flat state. In the two-parameter shape space, zero net rotation for elliptical trajectories occurs mainly with bilateral or antipodal symmetry. These symmetric subspaces have about the same peak efficiency as the full space but with much smaller dimension. Adding modes with two or three times the basic frequency greatly increases the numbers of local optimal for efficiency, but only modestly increases the peak efficiency. Random ensembles with higher frequencies have efficiency distributions that peak near a certain nonzero value and decay rapidly up to the maximum efficiency. A stochastic optimization algorithm is developed to compute optima with higher frequencies. These are simple closed curves, sharpened versions of the elliptical optima in most cases, and achieve much higher efficiencies mainly for small normal friction. With a linear resistance law, the optimal trajectories are similar in much of friction coefficient space, and relative efficiencies are much lower except with very large normal friction.

description: Abstract: The morbimortality of severe burns continues to be considerable and a serious public health problem. This is largely due to the state of immunosuppression of burn patients caused by the loss of the skin barrier that offers protection against the entry of microorganisms, with wound infection being one of the most common complications. For this reason, the main objective of this study is to determine the factors that intervene in the process of burn wound infection during hospitalisation in the Major Burn Unit, where an optimal interpretation of the same should be carried out, as well as continuous and meticulous follow-up. 

Se realizará un estudio de tipo analítico con un enfoque cuantitativo y diseño observacional prospectivo de casos y controles. Por otro lado, se tratará de un estudio longitudinal llevando a cabo el seguimiento de determinados procesos (variables) y sujetos durante un tiempo determinado  establecido entre marzo 2023 y septiembre de 2024.  

 

Resumen: La morbimortalidad del gran quemado continúa siendo considerable y un grave problema de salud pública. Esto se debe en gran parte, al estado de inmunosupresión de los pacientes quemados provocado por la pérdida de la barrera cutánea que ofrece protección frente a la entrada de microorganismos, siendo la infección de la herida, una de las complicaciones más comunes. Es por ello por lo que el objetivo principal de este trabajo es determinar los factores que intervienen en el proceso de infección de la herida por quemadura durante la hospitalización en la unidad de Gran Quemado donde se deberá llevar a cabo una óptima interpretación de la misma, así como un continuo y meticuloso seguimiento. 

An analytical study will be carried out with a quantitative approach and a prospective observational design of cases and controls. On the other hand, it will be a longitudinal study carrying out the follow-up of certain processes (variables) and subjects during a determined period of time established between March 2023 and Setember 2024.

description: We report on the exchange bias between antiferromagnetic and ferroelectric hexagonal YMnO3 epitaxial thin films sandwiched between a metallic electrode (Pt) and a soft ferromagnetic layer (Py). Anisotropic magnetoresistance measurements are performed to monitor the presence of an exchange bias field. When the heteroestructure is biased by an electric field, it turns out that the exchange bias field is suppressed. We discuss the dependence of the observed effect on the amplitude and polarity of the electric field. Particular attention is devoted to the role of current leakage across the ferroelectric layer.

description: An exciton is an electron-hole pair bound by attractive Coulomb interaction. Short-lived excitons have been detected by a variety of experimental probes in numerous contexts. An excitonic insulator, a collective state of such excitons, has been more elusive. Here, thanks to Nernst measurements in pulsed magnetic fields, we show that in graphite there is a critical temperature (T = 9.2 K) and a critical magnetic field (B = 47 T) for Bose-Einstein condensation of excitons. At this critical field, hole and electron Landau sub-bands simultaneously cross the Fermi level and allow exciton formation. By quantifying the effective mass and the spatial separation of the excitons in the basal plane, we show that the degeneracy temperature of the excitonic fluid corresponds to this critical temperature. This identification would explain why the field-induced transition observed in graphite is not a universal feature of three-dimensional electron systems pushed beyond the quantum limit.

Conditional Density Operators and the Subjectivity of Quantum Operations

Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Assuming that quantum states, including pure states, represent subjective degrees of belief rather than objective properties of systems, the question of what other elements of the quantum formalism must also be taken as subjective is addressed. In particular, we ask this of the dynamical aspects of the formalism, such as Hamiltonians and unitary operators. Whilst some operations, such as the update maps corresponding to a complete projective measurement, must be subjective, the situation is not so clear in other cases. Here, it is argued that all trace preserving completely positive maps, including unitary operators, should be regarded as subjective, in the same sense as a classical conditional probability distribution. The argument is based on a reworking of the Choi-Jamiolkowski isomorphism in terms of "conditional" density operators and trace preserving completely positive maps, which mimics the relationship between conditional probabilities and stochastic maps in classical probability.

LOGISTIC REGRESSION MODELING FOR DETERMINANTS OF CHILDHOOD VACCINATION UPTAKE IN GHANA: A POPULATION-BASED STUDY
Creators: name: A. Dinesh Kumar & Jerryson Ameworgbe Gidisu
Publisher: name: Zenodo
Year: 2025

description: Childhood vaccination remains a cornerstone of public health, yet in Ghana, significant disparities persist, particularly in rural and low-income settings. This study addresses a critical gap by applying logistic regression modeling to population-based data from 2020 to 2024, aiming to identify the determinants influencing full vaccination uptake among children aged 12-23 months. Using a sample of 1,000 respondents extracted from the Ghana Demographic and Health Survey and supplemented by Ghana Health Service and UNICEF data, the research employed binary logistic regression, chi-square, ANOVA, and Pearson correlation analyses to examine variables such as maternal education, household wealth, and health service accessibility. The findings revealed that maternal education (OR = 2.10, p < 0.001), household wealth (OR = 1.85, p < 0.001), proximity to clinics (OR = 0.70, p = 0.002), and antenatal care visits (OR = 2.35, p < 0.001) were significant predictors of full vaccination. A strong inverse correlation was observed between distance to clinics and vaccination uptake (r = -0.72, p < 0.001), while the overall model showed excellent fit (Nagelkerke R² = 0.48; Hosmer-Lemeshow p = 0.57). The interaction of high maternal education and wealth yielded a 91.2% predicted probability of full vaccination, compared to just 54.7% among children with neither. These results imply that tailored interventions focusing on education, economic support, and healthcare access can substantially enhance immunization coverage. The study recommends integrated strategies, including conditional cash transfers, mobile clinics, and female literacy programs, to bridge existing gaps and meet the WHO’s 95% vaccination target.

description: Nearly all of the well studied ancient globular clusters (GCs), in the Milky Way and in nearby galaxies, show star-to-star variations in specific elements (e.g., He, C, N, O, Na, Al), known as "multiple populations" (MPs). However, MPs are not restricted to ancient clusters, with massive clusters down to $\sim2$ Gyr showing signs of chemical variations. This suggests that young and old clusters share the same formation mechanism but most of the work to date on younger clusters has focused on N-variations. Initial studies even suggested that younger clusters may not host spreads in other elements beyond N (e.g., Na), calling into question whether these abundance variations share the same origin as in the older GCs. In this work, we combine HST photometry with VLT/MUSE spectroscopy of a large sample of RGB stars (338) in the Large Magellanic Cloud cluster NGC 1978, the youngest globular to date with reported MPs in the form of N-spreads. By combining the spectra of individual RGB stars into N-normal and N-enhanced samples, based on the "chromosome map" derived from HST, we search for mean abundance variations. Based on the NaD line, we find a Na-difference of $Δ$[Na/Fe]$=0.07\pm0.01$ between the populations. While this difference is smaller than typically found in ancient GCs (which may suggest a correlation with age), this result further confirms that the MP phenomenon is the same, regardless of cluster age and host galaxy. As such, these young clusters offer some of the strictest tests for theories on the origin of MPs.

Στόχος είναι η αποκρυστάλλωση των απόψεών του περί της εθνικής λογοτεχνίας, της ρομαντικής και φυσιολογικής σχολής, του πραγματικού και του ιδανικού, της εθνικής γλώσσας και του Ζολά. Εξετάζεται, ακόμα, η ορθότητα του όρου ‘μανιφέστο του νατουραλισμού’ που αποδίδεται στην «Διατριβή». Στη συνέχεια, διερευνάται η πιθανότητα σύνδεσης του Α.Γ.Η. με τον πνευματικό χώρο της Ιταλίας και την ιταλική κριτική με κυρίαρχη τη μορφή του Francesco De Sanctis και το έργο του Studio sopra Emilio Zola. Στο τέλος, συζητούνται οι συγκλίσεις και οι αποκλίσεις που προέκυψαν από την ανάλυση αυτών των δύο έργων.
description: This dissertation aims at present the literary activity of Agisilaos Giannopoulos, during his youth and stay in Italy (1876-1889), through the articles that have been published in greek newspapers and magazines and particularly his work ‘Επιστολιμαία διατριβή’. One of the main goals of this dissertation is to define his views, regarding, national literature, the romantic and physiological school, the real and ideal, the national language and Zola. In addition, under inspection is the correctness of the term "manifest of naturalism" which is attributed to this work. Following that, the possibility of Agisilaos Giannopoulos’ connection with the academic circles in Italy and the Italian criticism, and in particular with Francesco De Sanctis and his work ‘Studio sopra Emilio Zola’, is examined. In the final section, similarities and contradictions between this two works are being discussed.

Policy sector convergence: an examination of aboriginal politics and forestry policy in British Columbia
Creators: name: Morawski, Edward Roger
Publisher: name: University of British Columbia
Year: 2009

description: British Columbia is undergoing a transformation in both its forestry policy regime and its regime governing aboriginal policy. Forestry policy has evolved from what once was a closed network, dominated by the ministry of forests and the forestry industry, to a more expansive network that includes a variety of interests. British Columbia's aboriginal policy now recognizes the legitimacy of aboriginal claims to traditional territories, and has correspondingly initiated a treaty negotiation process with B.C.'s First Nations. A synthesis has emerged between aboriginal politics and the provincial forestry regime in some parts of the province. Consequently, two independant policy sectors have converged and this new policy phenomenon has been unexplored by political scientists. Clayoquot Sound, on the west coast of Vancouver Island, is an area at the forefront of forestry policy development. This thesis, therefore, uses Clayoquot Sound as a case study of sector convergence. In doing so, this thesis explains the phenomena of inter-sector penetration and explores its consequences to policy theory.

description: The acoustic modes of diamond not only are of profound significance for studying its thermal conductivity, mechanical properties and optical properties, but also play a determined role in the performance of high-frequency and high-power acoustic wave devices. Here we report the bulk acoustic waves (BAWs) and surface acoustic waves (SAWs) of single crystal diamond by using the angle-resolved Brillouin light scattering (BLS) spectroscopy. We identify two high-velocity surface skimming bulk waves, with sound velocities of 1.277x10^6 and 1.727x10^6 cm/s, respectively. Furthermore, we conduct the relationship among the refractive index, incident angle and the velocities of BAWs propagating along an arbitrary direction. Our results may provide a valuable reference for fundamental researches and devices engineering in the community of diamond-based acoustic study.

description: We derive an approximate but fully explicit formula for the mean first-passage time (MFPT) to a small absorbing target of arbitrary shape in a general elongated domain in the plane. Our approximation combines conformal mapping, boundary homogenisation, and Fick-Jacobs equation to express the MFPT in terms of diffusivity and geometric parameters. A systematic comparison with a numerical solution of the original problem validates its accuracy when the starting point is not too close to the target. This is a practical tool for a rapid estimation of the MFPT for various applications in chemical physics and biology.

description: We study a separability problem suggested by mathematical description of bipartite quantum systems. We consider Hermitian 2-forms on the tensor product $H=K\otimes L$, where $K,L$ are finite dimensional complex spaces. Inspired by quantum mechanical terminology we call such a form separable if it is a convex combination of hermitian tensor products $(σ_p)^*\odot σ_p$ of 1-forms $σ_p$ on $H$ that are product forms $σ_p=ϕ_p\otimes ψ_p$, where $ϕ_p\in K^*$, $ψ_p\in L^*$. We introduce an integral representation of separable forms. In particular, we show that the integral of $(D_{z^*}}Φ)^*\odot D_{z^*}Φ$ of any square integrable map $Φ:\C^n\to \C^m$, with square integrable conjugate derivative $D_{z^*}Φ$, is a separable form. Vice versa, any separable form in the interior of the set of such forms, can be represented in this way. This implies that any separable mixed state (and only such states) can be either explicitly represented in the integral form, or it may be arbitrarily well approximated by such states.

Nonequivalent operator representations for Bose-condensed systems

description: The necessity of accurately taking into account the existence of nonequivalent operator representations, associated with canonical transformations, is discussed. It is demonstrated that Bose systems in the presence of the Bose-Einstein condensate and without it correspond to different Fock spaces, orthogonal to each other. A composite representation for the field operators is constructed, allowing for a self-consistent description of Bose-condensed systems. Equations of motion are derived from the given Hamiltonian, which guarantees the validity of conservation laws and thermodynamic self-consistency. At the same time, the particle spectrum, obtained either from diagonalizing this Hamiltonian or from linearizing the field-operator equations of motion, has no gap. The condition of the condensate existence assures the absence of the gap in the spectrum, irrespectively to the approximation involved. The suggested self-consistent theory is both conserving and gapless.

Sulla fraternità
Creators: name: Palmentura, Eleonora
Publisher: name: Apulia Theologica
Year: 2025

description: Nel contesto attuale, la fraternità sembra soccombere piagata da conflitti tra popoli che spesso si sono considerati fratelli. Occorre allora fare memoria della storia di questo lemma ambivalente e della sua alterna fortuna nella storia del pensiero, per cercare cosa è andato perso e dargli fondamento, senza cedere a una categoria di fraternità astratta e senza giustificare particolarismi settari ed escludenti. Il recupero dell'origine filiale e della trascendenza dei volti che costituiscono un richiamo etico alla responsabilità verso fratelli e sorelle mostra come la fraternità vada oltre l'aspetto biologico e possa declinarsi in modo universale. Essa custodisce le differenze ma edifica la comunione di tutti e tutte, attraverso la sua radice affettiva di compassione e pietà e il riconoscimento della comune umanità vulnerabile. Ricordare il perché della fraternità è funzionale ad assumerla come categoria di pensiero e progettazione politica e a riscoprire la vocazione originaria dell'umano.

description: We provide a determination of the isotriplet quark distribution from available deep--inelastic data using neural networks. We give a general introduction to the neural network approach to parton distributions, which provides a solution to the problem of constructing a faithful and unbiased probability distribution of parton densities based on available experimental information. We discuss in detail the techniques which are necessary in order to construct a Monte Carlo representation of the data, to construct and evolve neural parton distributions, and to train them in such a way that the correct statistical features of the data are reproduced. We present the results of the application of this method to the determination of the nonsinglet quark distribution up to next--to--next--to--leading order, and compare them with those obtained using other approaches.

Characteristics of reaction-diffusion on scale-free networks

description: We examine some characteristic properties of reaction-diffusion processes of the A+A->0 type on scale-free networks. Due to the inhomogeneity of the structure of the substrate, as compared to usual lattices, we focus on the characteristics of the nodes where the annihilations occur. We show that at early times the majority of these events take place on low-connectivity nodes, while as time advances the process moves towards the high-connectivity nodes, the so-called hubs. This pattern remarkably accelerates the annihilation of the particles, and it is in agreement with earlier predictions that the rates of reaction-diffusion processes on scale-free networks are much faster than the equivalent ones on lattice systems.

description: We develop a parallel optically detected magnetic resonance (PODMR) spectrometer to address, manipulate and read out an array of single nitrogen-vacancy (NV) centers in diamond in parallel. In this spectrometer, we use an array of micro-lens to generate 20 * 20 laser-spot lattice (LSL) on the objective focal plane, and then align the LSL with an array of single NV centers. The quantum states of NV centers are manipulated by a uniform microwave field from a Ω-shape coplanar coil. As an experimental demonstration, we observe 80 NV centers in the field of view. Among them, magnetic resonance (MR) spectrums and Rabi oscillations of 18 NV centers along the external magnetic field are measured in parallel. These results can be directly used to realize parallel quantum sensing and multiple times speedup compared with the confocal technique. Regarding the nanoscale MR technique, PODMR will be crucial for high throughput single molecular MR spectrum and imaging.

description: We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for Supernovae (ASAS-SN), it was classified as a supernova close to the nucleus. The subsequent six years of V- and g-band ASAS-SN observations reveal that ASASSN-14ko has nuclear flares occurring at regular intervals. The seventeen observed outbursts show evidence of a decreasing period over time, with a mean period of $P_0 = 114.2 \pm 0.4$ days and a period derivative of $\dot{P} = -0.0017\pm0.0003$. The most recent outburst in May 2020, which took place as predicted, exhibited spectroscopic changes during the rise and a had a UV bright, blackbody spectral energy distribution similar to tidal disruption events (TDEs). The X-ray flux decreased by a factor of 4 at the beginning of the outburst and then returned to its quiescent flux after ~8 days. TESS observed an outburst during Sectors 4-6, revealing a rise time of $5.60 \pm 0.05$ days in the optical and a decline that is best fit with an exponential model. We discuss several possible scenarios to explain ASASSN-14ko's periodic outbursts, but currently favor a repeated partial TDE. The next outbursts should peak in the optical on UT 2020-09-7.4$ \pm $1.1 and UT 2020-12-26.5$ \pm $1.4.
