description: We combine the semi-analytical structure formation model, SASHIMI, which predicts subhalo populations in collisionless, cold dark matter (CDM), with a parametric model that maps CDM halos to self-interacting dark matter (SIDM) halos. The resulting model, SASHIMI-SIDM, generates SIDM subhalo populations down to sub-galactic mass scales, for an arbitrary input cross section, in minutes. We show that SASHIMI-SIDM agrees with SIDM subhalo populations from high-resolution cosmological zoom-in simulations in resolved regimes. Crucially, we predict that the fraction of core-collapsed subhalos peaks at a mass scale determined by the input SIDM cross section and decreases toward higher halo masses, consistent with the predictions of gravothermal models and cosmological simulations. For the first time, we also show that the core-collapsed fraction decreases toward lower halo masses. While the dependence of the collapse time on mass and concentration implies such behaviour, our semi-analytical approach allows us to quantify and illustrate this trend clearly across the full mass spectrum of subhalos, including for subhalo masses below the resolution limit of any current cosmological SIDM simulation. As a proof of principle, we apply SASHIMI-SIDM to predict the boost to the local dark matter density and annihilation rate from core-collapsed SIDM subhalos, which can be enhanced relative to CDM by an order of magnitude for viable SIDM models. Thus, SASHIMI-SIDM provides an efficient and reliable tool for scanning SIDM parameter space and testing it with astrophysical observations.

Early soft X-ray to UV emission from double neutron star mergers: implications from the long-term radio and X-ray emissions of GW 170817

description: Recent long-term radio follow-up observations of GW 170817 reveals a simple power-law rising light curve, with a slope of $t^{0.78}$, up to 93 days after the merger. The latest X-ray detection at 109 days is also consistent with such a temporal slope. Such a shallow rise behavior requires a mildly relativistic outflow with a steep velocity gradient profile, so that slower material with larger energy catches up with the decelerating ejecta and re-energizes it. It has been suggested that this mildly relativistic outflow may represent a cocoon of material. We suggest that the velocity gradient profile may form during the stage that the cocoon is breaking out of the merger ejecta, resulted from shock propagation down a density gradient. The cooling of the hot relativistic cocoon material immediately after it breaks out should have produced soft X-ray to UV radiation at tens of seconds to hours after the merger. The soft X-ray emission has a luminosity of $L_{\rm X}\sim 10^{45}{\rm erg s^{-1}}$ over a period of tens of seconds for a merger event like GW 170817. The UV emission shows a rise initially and peaks at about a few hours with a luminosity of $L_{\rm UV}\sim 10^{42} {\rm erg s^{-1}}$. The soft X-ray transients could be detected by future wide-angle X-ray detectors, such as the Chinese mission Einstein Probe. This soft X-ray/UV emission would serve as one of the earliest electromagnetic counterparts of gravitation waves from double neutron star mergers and could provide the earliest localization of the sources.

description: Non-malleable codes, introduced by Dziembowski, Pietrzak and Wichs (ICS 2010), encode messages s in a manner so that tampering the codeword causes the decoder to either output s or a message that is independent of s. While this is an impossible goal to achieve against unrestricted tampering functions, rather surprisingly non-malleable coding becomes possible against every fixed family F of tampering functions that is not too large (for instance, when lF| ≤ 22αn for some α < 1 where n is the number of bits in a codeword). In this work, we study the "capacity of non-malleable coding", and establish optimal bounds on the achievable rate as a function of the family size, answering an open problem from Dziembowski et al. (ICS 2010). Specifically, We prove that for every family F with lF| ≤ 22αn, there exist non-malleable codes against F with rate arbitrarily close to 1 - α (this is achieved w.h.p. by a randomized construction). We show the existence of families of size exp(;nO(1) 2αn) against which there is no non-malleable code of rate 1 - α (in fact this is the case w.h.p for a random family of this size). We also show that 1 - α is the best achievable rate for the family of functions which are only allowed to tamper the first αn bits of the codeword, which is of special interest. As a corollary, this implies that the capacity of non-malleable coding in the split-state model (where the tampering function acts independently but arbitrarily on the two halves of the codeword, a model which has received some attention recently) equals 1/2. We also give an efficient Monte Carlo construction of codes of rate close to 1 with polynomial time encoding and decoding that is non-malleable against any fixed c > 0 and family F of size 2nc, in particular tampering functions with, say, cubic size circuits.

description: Bilayer ruthenate Ca$_3$(Ru$_{1-x}$Fe$_x$)$_2$O$_7$ ($x$ = 0.05) exhibits an incommensurate magnetic soliton lattice driven by the Dzyaloshinskii-Moriya interaction. Here we report complex field-induced magnetic phase transitions and memory effect in this system via single-crystal neutron diffraction and magnetotransport measurements. We observe first-order incommensurate-to-commensurate magnetic transitions upon applying the magnetic field both along and perpendicular to the propagation axis of the incommensurate spin structure. Furthermore, we find that the metastable states formed upon decreasing the magnetic field depend on the temperature and the applied field orientation. We suggest that the observed field-induced metastability may be ascribable to the quenched kinetics at low temperature.

description: Vehicular networks are one of the cornerstone of an Intelligent Transportation System (ITS). They are expected to provide ubiquitous network connectivity to moving vehicles while supporting various ITS services, some with very stringent requirements in terms of latency and reliability. Two vehicular networking technologies are envisioned to jointly support the full range of ITS services : DSRC (Dedicated Short Range Communication) for direct vehicle to vehicle/Road Side Units (RSU) communications and cellular technologies. To the best of our knowledge, approaches from the literature usually divide ITS services on each of these networks according to their requirements and one single network is in charge of supporting the each service. Those that consider both network technologies to offer multi-path routing, load balancing or path splitting for a better quality of experience of ITS services assume obviously separately controlled networks. Under the umbrella of SDN (Software Defined Networking), we propose in this paper a hybrid network architecture that enables the joint control of the networks providing connectivity to multi-homed vehicles and, also, explore the opportunities brought by such an architecture. We show through some use cases, that in addition to the flexibility and fine-grained programmability brought by SDN, it opens the way towards the development of effective network control algorithms that are the key towards the successful support of ITS services and especially those with stringent QoS. We also show how these algorithms could also benefit from information related to the environment or context in which vehicles evolve (traffic density, planned trajectory, ..), which could be easily collected by data providers and made available via the cloud.

description: We investigate the flavour structure of generic extensions of the SM where quark and lepton mass hierarchies and the suppression of flavour-changing transitions originate only by the normalization constants of the fermion kinetic terms. We show that in such scenarios the contributions to quark FCNC transitions from dimension-six effective operators are sufficiently suppressed without (or with modest) fine tuning in the effective scale of new physics. The most serious challenge to this type of scenarios appears in the lepton sector, thanks to the stringent bounds on LFV. The phenomenological consequences of this scenarios in view of improved experimental data on quark and lepton FCNC transitions, and its differences with respect to the Minimal Flavour Violation hypothesis are also discussed.

description: Storage and retrieval of parametric down-conversion (PDC) photons are demonstrated with electromagnetically induced transparency (EIT). Extreme frequency filtering is performed for THz order of broadband PDC light and the frequency bandwidth of the light is reduced to MHz order. Storage and retrieval procedures are carried out for the frequency filtered PDC photons. Since the filtered bandwidth [full width at half-maximum (FWHM) = 9 MHz] is within the EIT window (FWHM = 12.6 MHz), the flux of the PDC light is successfully stored and retrieved. The nonclassicality of the retrieved light is confirmed by using photon counting method, where the classical inequality which is only satisfied for classical light fields is introduced. Since the PDC photons can be utilized for producing the single photon state conditionally, storage and retrieval procedures are also performed for the conditional single photons. Anti-correlation parameter used for checking the property of single photon state shows the value less than 1, which means the retrieved light is in a non-classical region.

description: Exemplar-Free Class Incremental Learning is a highly challenging setting where replay memory is unavailable. Methods relying on frozen feature extractors have drawn attention recently in this setting due to their impressive performances and lower computational costs. However, those methods are highly dependent on the data used to train the feature extractor and may struggle when an insufficient amount of classes are available during the first incremental step. To overcome this limitation, we propose to use a pre-trained text-to-image diffusion model in order to generate synthetic images of future classes and use them to train the feature extractor. Experiments on the standard benchmarks CIFAR100 and ImageNet-Subset demonstrate that our proposed method can be used to improve state-of-the-art methods for exemplar-free class incremental learning, especially in the most difficult settings where the first incremental step only contains few classes. Moreover, we show that using synthetic samples of future classes achieves higher performance than using real data from different classes, paving the way for better and less costly pre-training methods for incremental learning.

description: Accretion onto black holes often proceeds via an accretion disk or a temporary disk-like pattern. Variability features observed in light curves as well as theoretical models of accretion flows suggest that accretion disks tend to be inhomogeneous -- variety of substructures (clumps) emerge within the flow. Rapid orbital motion of individual clumps then modulates the observed signal in X-rays. Furthermore, changes of spectral lines and polarization properties of the observed signal (or the absence of changes) constrain the models and reveal information about general relativity (GR) effects. In this write-up we summarize the basic equations that have been employed to study light propagation near black holes and to derive the radiation signal that can be expected at a detector within the framework of geometrical optics approximation.

description: We continue the program of constructing cubic interactions between matter and higher spin supermultiplets. In this work we consider a complex linear superfield and we find that it can have cubic interactions only with supermultiplets with propagating spins $j=s+1$, $j=s+1/2$ for any non-negative integer $s$ (half-integer superspin supermultiplets). We construct the higher spin supercurrent and supertrace, these compose the canonical supercurrent multiplet which generates the cubic interactions. We also prove that for every $s$ there exist an alternative minimal supercurrent multiplet, with vanishing supertrace. Furthermore, we perform a duality transformation in order to make contact with the corresponding chiral theory. An interesting result is that the dual chiral theory has the same coupling constant with the complex linear theory only for odd values of $s$, whereas for even values of $s$ the coupling constants for the two theories have opposite signs. Additionally we explore the component structure of the supercurrent multiplet and derive the higher spin currents. We find two bosonic currents for spins $j=s$ and $j=s+1$ and one fermionic current for spin $j=s+1/2$.

description: This bibliography is part of a study of cooperation among local governments in rural areas. Information about materials on this topic has not previously been readily available. Because agricultural areas may benefit from experience with interlocal cooperation in urban areas, the bibliography includes materials reporting such experience. Thus, it also serves as a source of information for those concerned with problems of general local government. The term intergovernmental relations has been employed so often to refer to the relations of the Federal, State, and local governments that the term has come to mean the vertical flow of influences among these governments. Our interest is limited to the relationship among local governments, and of a special kind--interlocal governmental cooperation.

description: It has long been appreciated that superalgebras with bosonic and fermionic generators additional to those in the super-Poincare algebra underlie p-brane and D-brane actions in superstring theory. These algebras have been revealed via "bottom up" approaches, involving consideration of Noether charges, and by "top down" approaches, involving the construction of manifestly supersymmetry invariant Wess-Zumino actions. In this paper, we give an alternative derivation of these algebras based on integrability of supersymmetry transformations assigned to fields in order to solve a cohomology problem related to the construction of Wess-Zumino terms for p-brane and D-brane actions.

description: Imagine a cake that must be divided between a group of gluttonous children. To complicate matters, the cake is heterogeneous: two pieces of cake may differ in terms of their toppings, so the children have different preferences over the pieces (one may prefer a larger proportion of chocolate curls, while another may single-mindedly desire the piece with the cherry). In this chapter we discuss the surprisingly intricate problem of fairly dividing the cake — which serves as a metaphor for heterogeneous divisible resources such as land or time. The cake cutting problem has a long and storied history described, e.g., in the books by Brams and Taylor (1996) and Robertson and Webb (1998). The early research on the problem has two main themes: existence results showing that certain fairness guarantees can be achieved; and algorithmic results showing how such guarantees can be achieved. The focus of this chapter is on the latter theme, which has a more computational flavor. From a computer scientist’s point of view, the cake cutting problem provides a sandbox in which we can explore the role of computational thinking in the allocation of divisible goods. Indeed, the elegant cake cutting model (Section 13.2) distills many of the issues we care about when studying divisible goods more broadly; for example, how to reason about computational complexity in the face of continuous inputs, and how to quantify the tradeoffs between individual fairness and global welfare.

While the loss mechanisms have been heavily studied, noise in superconducting resonators has only recently been investigated. In particular, there is an absence of literature on noise in the single photon limit. Here, we measure the loss and noise of an aluminium on silicon quarter-wavelength ($λ/4$) resonator in the single photon regime.

description: We show that the efficiency of manipulating electron spin in semiconductor quantum wells can be enhanced by tuning the strain strength. The effect combining intrinsic and strain-induced spin splitting varies for different systems, which provides an alternative route to understand the experimental phenomena brought in by the strain. The types of spin splittings caused by strain are suggested to be distinguished by the measurement of the electron-dipole-spin-resonance intensity through changing the direction of the $ac$ electric field in the $x$-$y$ plane of the quantum well and tuning the strain strengths.

Méthodes : Il s’agit d’une recherche documentaire qualitative mobilisant des études scientifiques, des rapports gouvernementaux, internationaux et d’organisations non-gouvernementales. Résultats : L’éducation des Sénégalaises connaît une amélioration sans précédent actuellement. Les jeunes filles sont plus nombreuses à poursuivre leurs études au secondaire. L’augmentation de l’éducation des femmes se traduit par une meilleure connaissance, un plus grand contrôle et un retard dans le commencement de leur santé sexuelle et reproductive. En revanche, les coutumes sociales, la religion, les opinions personnelles tout comme le bien-être économique et le lieu de résidence sont tous des obstacles au plein contrôle de leur santé sexuelle et reproductive. Conclusions : Cette recherche met en lumière l’importance déterminante qu’à l’éducation dans l’atteinte de l’autonomisation. Il s’agit d’une variable indéniable qui mérite d’être approfondie et étudiée dans une variété de contexte. Pour réellement comprendre l’impact de l’éducation sur la santé sexuelle et reproductive, il est impératif de voir l’atteinte de l’autonomisation comme un processus multidimensionnel nécessitant la juxtaposition de multiples variables.

description: We consider mixtures of two species of spherical colloidal particles that differ in their hydrodynamic radii, but are otherwise identical, in the presence of an external field. Since the particle-particle and particle-field interactions are the same for both species, they are completely mixed in the thermodynamic limit in the presence of any static field. Here, we combine Brownian Dynamics and Dynamic Density Functional theory of fluids to show that for sufficiently large differences in the hydrodynamic radius of the particles (and corresponding differences in their electrophoretic mobilities) dynamical demixing is observed. These demixed states are transient but, under certain conditions, packing effects compromise the relaxation towards the thermodynamic states and the lifetime of the demixed phases increases significantly.

description: Chimeric antigen receptor (CAR) T cell performance against solid tumors in mouse models and clinical trials is often less effective than predicted by CAR construct selection in two-dimensional (2D) cocultures. Three-dimensional (3D) solid tumor architecture is likely to be crucial for CAR T cell efficacy. We used a three-dimensional (3D) bioprinting approach for large-scale generation of highly reproducible 3D human tumor models for the test case, neuroblastoma, and compared these to 2D cocultures for evaluation of CAR T cells targeting the L1 cell adhesion molecule, L1CAM. CAR T cells infiltrated the model, and both CAR T and tumor cells were viable for long-term experiments and could be isolated as single-cell suspensions for whole-cell assays quantifying CAR T cell activation, effector function and tumor cell cytotoxicity. L1CAM-specific CAR T cell activation by neuroblastoma cells was stronger in the 3D model than in 2D cocultures, but neuroblastoma cell lysis was lower. The bioprinted 3D neuroblastoma model is highly reproducible and allows detection and quantification of CAR T cell tumor infiltration, representing a superior in vitro analysis tool for preclinical CAR T cell characterization likely to better select CAR T cells for in vivo performance than 2D cocultures.

description: Domestic greywater produced via household chores has a major contribution to environmental pollution and is also the best-untapped energy source. Since the past decade, in the different fields, enormous efforts have been made to reach the bio-energy from bio-waste. These efforts consist of a wide range of thermochemical, bio-chemical, and microbial fuel cells; etc. however, all these efforts are in their infancy. They have high cost and are efficient on a large-scale; furthermore, these efforts used a non-intelligent process that has led to lack of development in this type of review. This ongoing research presents the smart design process that leads to hybrid energy via the intersection of computation, wastewater, and microorganisms and aims to introduce the novel bio-computational machine based on particle Physics. Therefore, we will investigate the mixture of the microbial fuel cells, specifically “Spirulina” micro-algae, and household chores greywater. In the computational framework, we propose high-precise fluid simulation with the advantage of particle position and dynamic physics for the conversion of the mixture of “Spirulina medium,” and household chore greywater makes energy control possible through flow, and management of the type of solution mix, by transferring data from the modules to the digital environment. Finally, these datasets simulate behavior based on the physical properties of each particle. The procedure works in a parametric computer-aided design (CAD) environment and through Grasshopper within Rhinoceros Software by syncing bio-computational machine to the digital environment. The solenoid valve and fluid flow controller applied between the nutritious tank and energy conversion tank measure nutritional consumption and sends it to the digital environment numerically with an Arduino-Uno board kit. These batch numerical signals are stored in our local database then are combined with the particle physics engine and simulate the material behavior; also, they provide the ability to control our bio-computational machine digitally.

description: Let $X$ be a metric space. Recently in~[1] it was considered a new type of mappings $T\colon X\to X$ which can be characterized as mappings contracting perimeters of triangles. These mappings are defined by the condition based on the mapping of three points of the space instead of two, as it is adopted in many fixed-point theorems. In the present paper we consider so-called $(F,G)$-contracting mappings, which form a more general class of mappings than mappings contracting perimeters of triangles. The fixed-point theorem for these mappings is proved. We prove also a fixed-point theorem for mappings contracting perimeters of triangles in the sense of Edelstein.

description: Berlin verfolgt das Ziel, sich bis zum Jahr 2050 zu einer klimaneutralen Stadt zu entwickeln: Im Vergleich zur Gesamtsumme der CO2-Emissionen des Jahres 1990, sollen diese bis 2030 um mindestens 60 Prozent und bis zum Jahr 2050 um mindestens 85 Prozent verringert werden. Fast ein Drittel der CO2-Emissionen in Deutschland kann dem Gebäudebereich zugerechnet werden. Einen enormen Hebel zur Verbesserung der Klimabilanz bietet der konsequente Einsatz von Baumaterialien auf Basis nachwachsender Rohstoffe. Insbesondere der Baustoff Holz kann für die Metropolregion Berlin-Brandenburg eine zentrale Stellung zur Erreichung der Klimaziele einnehmen. Hierzu wurde bereits im Frühjahr 2021, in der Vorhabensliste1 des Strategischen Gesamtrahmens Hauptstadtregion, eine regionale Holzbau-Offensive festgehalten. Diese hat zum Ziel, die Region Berlin-Brandenburg zu einer Region des Holzbaus zu entwickeln. Damit die holzbasierte Transformation des Bauens in der Hauptstadtregion nachhaltig gelingt, ist insbesondere eine starke kreislaufwirtschaftsbasierte regionale Holzbauwirtschaft von Bedeutung.
Whose Culture Is It? Trans-generational Approaches to Culture in Canada

description: This short paper was developed in response to a questionnaire prepared by CIRCLE (Cultural Information and Research Centres Liaison in Europe) for its 2004 Round Table in Barcelona, Spain. The purpose of the questionnaire was to identify the main trends in youth culture today and to determine whether youth culture differs more from mainstream culture than in earlier generations. The central research question to be explored was whether a new type of culture, network culture – characterized by the predominance of virtual rather than face-to-face relationships – was emerging.

description: Light induced current in two-dimensional (2D) layered materials emerges from mechanisms such as photothermoelectric effect, photovoltaic effect or nonlocal hot carrier transport. Semiconducting layered transition metal dichalcogenides have been studied extensively in recent years as the generation of current by light is a crucial process in optoelectronic and photovoltaic devices. However, photocurrent generation is unexpected in metallic 2D layered materials unless a photothermal mechanism is prevalent. Typically, high thermal conductivity and low absorption of the visible spectrum prevent photothermal current generation in metals. Here, we report photoresponse from two-terminal devices of mechanically exfoliated metallic 3R-NbS$_2$ thin crystals using scanning photocurrent microscopy (SPCM) both at zero and finite bias. SPCM measurements reveal that the photocurrent predominantly emerges from metal/NbS$_2$ junctions of the two-terminal device at zero bias. At finite biases, along with the photocurrent generated at metal/NbS$_2$ junctions, now a negative photoresponse from all over the NbS$_2$ crystal is evident. Among our results, we realized that the observed photocurrent can be explained by the local heating caused by the laser excitation. These findings show that NbS$_2$ is among a few metallic materials in which photocurrent generation is possible.

description: For a stationary spacetime metric, black holes are spatial regions which disturbances may not propagate out of. In our previous work an existence and regularity theorem was proven for black holes in two space dimensions, in the case where the boundary of the ergoregion is a simple closed curve surrounding a singularity. In this paper we study the case of an annular ergoregion, whose boundary has two components.

description: Within the framework of the gauge-invariant, but path-dependent, variables formalism, we study the connection between scale symmetry breaking and confinement in three-dimensional gluodynamics. We explicitly show that the static potential profile contains a linear potential, leading to the confinement of static charges. Also, we establish a new type of equivalence among different three-dimensional effective theories.

Resolving the paradox of the Dirac equation: phenomenology
Creators: name: Timashev, Serge F.

Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Based on the results of F. Wilf on the need to take into account the quantum-mechanical correspondence rules in the Dirac equation for an electron, it was shown that the equation obtained by giving physical meaning to $α$-Dirac operators should be considered as a phenomenological equation for a particle of non-zero size - the EM polaron, previously introduced by the author. This allows a solution to be found to the inherent paradox of the Dirac equation, which consists of the equality of the velocity of the moving particles to the speed of light $c$ in a vacuum, which is a priori unobtainable, and to understand the physical essence of spin as the intrinsic mechanical moment of an EM polaron. It is also shown that the Dirac-Wilf equation for a single spatial dimension can be considered a generalization of the Schrodinger equation for relativistic energies.

description: Il gelso è impiegato come alimento del bestiame in diversi paesi del mondo (come ad esempio in India e Giappone). Le foglie del gelso sono apprezzate per il loro elevato contenuto di proteine (15-28%), il buon profilo amminoacidico >46%), l'alta digeribilità (>80%), l´elevato contenuto di minerali con valori di ceneri fino a 25%, il basso contenuto di fibra (7,1-8,1%) ed l'eccellente appetibilità. L'elevata produzione di biomassa da parte della pianta, con un basso contenuto di tannini, rende la specie un'attrattiva risorsa per il bestiame. Quindi il gelso può contribuire ad integrare la disponibilità alimentare per il bestiame durante i periodi estivi, quando i pascoli in ambiente mediterraneo sono scarsamente produttivi.
Ordered states in the Kitaev-Heisenberg model: From 1D chains to 2D honeycomb

description: We study the ground state of the 1D Kitaev-Heisenberg (KH) model using the density-matrix renormalization group and Lanczos exact diagonalization methods. We obtain a rich ground-state phase diagram as a function of the ratio between Heisenberg ($J=\cosϕ)$ and Kitaev ($K=\sinϕ$) interactions. Depending on the ratio, the system exhibits four long-range ordered states: ferromagnetic-$z$ , ferromagnetic-$xy$, staggered-$xy$, Néel-$z$, and two liquid states: Tomonaga-Luttinger liquid and spiral-$xy$. The two Kitaev points $ϕ=\fracπ{2}$ and $ϕ=\frac{3π}{2}$ are singular. The $ϕ$-dependent phase diagram is similar to that for the 2D honeycomb-lattice KH model. Remarkably, all the ordered states of the honeycomb-lattice KH model can be interpreted in terms of the coupled KH chains. We also discuss the magnetic structure of the K-intercalated RuCl$_3$, a potential Kitaev material, in the framework of the 1D KH model. Furthermore, we demonstrate that the low-lying excitations of the 1D KH Hamiltonian can be explained within the combination of the known six-vertex model and spin-wave theory.

description: The LHCb has reported the observation of a resonancelike structure, the Pc(4450), in the J/psi p invariant masses. In our work, we discuss the feasibility of detecting this structure in J/psi photoproduction, e.g. in the measurements that have been approved for the experiments in Hall A/C and in Hall B with CLAS12 at JLab. Also the GlueX Collaboration has already reported preliminary results. We take into account the experimental resolution effects, and perform a global fit to world J/psi photoproduction data in order to study the possibility of observing the Pc(4450) signal in future JLab data. We present a first estimate of the upper limit for the branching ratio of the Pc(4450) into the J/psi p channel, and we study the angular distributions of the differential cross sections. This will shed light on the nature and couplings of the Pc(4450) structure in the future photoproduction experiments.
