A Stochastic Hamiltonian Approach for Quantum Jumps, Spontaneous Localizations, and Continuous Trajectories
Creators: name: Belavkin, V. P.

description: We give an explicit stochastic Hamiltonian model of discontinuous unitary evolution for quantum spontaneous jumps like in a system of atoms in quantum optics, or in a system of quantum particles that interacts singularly with "bubbles" which admit a continual counting observation. This model allows to watch a quantum trajectory in a photodetector or in a cloud chamber by spontaneous localisations of the momentums of the scattered photons or bubbles. Thus, the continuous reduction and spontaneous localization theory is obtained from a Hamiltonian singular interaction as a result of quantum filtering, i.e., a sequential time continuous conditioning of an input quantum process by the output measurement data. We show that in the case of indistinguishable particles or atoms the a posteriori dynamics is mixing, giving rise to an irreversible Boltzmann-type reduction equation. The latter coincides with the nonstochastic Schroedinger equation only in the mean field approximation, whereas the central limit yelds Gaussian mixing fluctuations described by a quantum state reduction equation of diffusive type.

description: We modify the pre-factor of the semiclassical propagator to improve its efficiency in practical implementations. The new pre-factor represents the smooth portion of an orbit's contribution, and leads to fast convergence in numerical calculations. As an illustration of the accuracy and efficiency of the resultant propagator, we numerically calculate overlaps between quantum and semiclassical wave functions, as well as low-lying spectrum density in a 10-dimensional system contains unstable classical orbits. This sheds light on applying semiclassical propagator to high dimensional systems.

description: The stationary state of a spherically symmetric plasma configuration is investigated in the limit of immobile ions and weak collisions. Configurations with small radii are positively charged as a significant fraction of the electron population evaporates during the equilibration process, leaving behind an electron distribution function with an energy cutoff. Such charged plasma configurations are of interest for the study of Coulomb explosions and ion acceleration from small clusters irradiated by ultraintense laser pulses and for the investigation of ion bunches propagation in a plasma.

description: In this study, a world model for the international market of coffee is developed and analyzed, considering its major exporters (Brazil, Colombia, Mexico, Africa, Central America and Asia) and its major importers (United States, Germany, Japan, France, Italy, Spain, Canada, United Kingdom, Holland). That model is, then, simulated for several shocks such as the reduction of barriers that would reduce prices of coffee in all import markets, an increase in income that would increase the world demand, and variations in production of Brazil and Asia. The results evaluated in the short and long run, indicated that the main effects on the coffee prices occurs when there are changes in production, especially in Brazil. The reductions of barriers have small effects in trade flows, and increases in international demand would benefit most exporters from Brazil and Mexico.

description: The coffee roasting segment is passing through deep transformation since the beginning of the 90´s, and the requirement of quality has been essential for the performance of those companies in the market. The quality factor has been playing important role for the competitiveness of the enterprises. Some authors believe that, under the aegis of the market globalization, the quality reaches its highest level of importance in the business decision process and turns out to be the passport for opening the most challenging markets and for upholding the niches in the more competitive markets. However, systems or quality programs generate costs that, usually, are unknown for the firms. In Brazil, the literature on the costs of the quality lacks more comprehensive studies. This paper aims to evaluate the costs of the quality in the coffee roasting industry in the Southeast of Brazil, in relation to some performance indicators, intended for those companies that adopt some quality program in its industrious process. The results point to that only some performance indicators get better in relation to the costs and that the companies don’t have a defined system of their cost measurements of the quality.
Pseudorapidity distributions of charged hadrons in lead-lead collisions at $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV

description: The pseudorapidity ($η$) distributions of charged hadrons are measured using data collected at the highest ever nucleon-nucleon center-of-mass energy of $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV for collisions of lead-lead ions. The data were recorded by the CMS experiment at the LHC in 2022 and correspond to an integrated luminosity of 0.30 $\pm$ 0.03 $μ$b$^{-1}$. Using the CMS silicon pixel detector, the yields of primary charged hadrons produced in the range $\vertη\vert$ $\lt$ 2.6 are reported. The evolution of the midrapidity particle density as a function of collision centrality is also reported. In the 5% most central collisions, the charged-hadron $η$ density in the range $\vertη\vert$ $\lt$ 0.5 is found to be 2032 $\pm$ 91 (syst), with negligible statistical uncertainty. This result is consistent with an extrapolation from nucleus-nucleus collision data at lower center-of-mass energies. Comparisons are made to various Monte Carlo event generators and to previous measurements of lead-lead and xenon-xenon collisions at similar collision energies. These new data detail the dependence of particle production on the collision energy, initial collision geometry, and the size of the colliding nuclei.

description: Az agrárüzem definiálása nemcsak a közgazdaságtan, hanem az agrárjog szempontjából is számos problémát vet fel. Szakmai körökben keveredik a mezőgazdasági üzem dologösszességkénti, illetve szervezeti forma szerinti megkülönböztetése. Az uniós jog ezzel szemben a mezőgazdasági üzemet önálló jogi kategóriának tekinti és épít arra, hogy a tagországok egységes üzemszabályozási törvényben állapítják meg a nemzeti agrárüzemek működtetésének jogi-közigazgatási kereteit. Ez a feltételezés azonban csak az Európai Unió nyugat-európai tagállamaira igaz. Bár egyes üzemszabályozási elemek a magyar jogban is megtalálhatók, azok nem az agrárüzemre mint absztrakt jogi kategóriára, hanem a mezőgazdasági vállalkozások egyes konkrét szervezeti formáira vonatkoznak. Hatályos agrárjogi szabályozásunknak további sajátossága, hogy az egyes speciális agrárüzemi szervezeti formák sem egységes keretjogszabályban, hanem esetlegesen, az adott időpontban és politikai erőtérben érvényesülő jogalkotói szándék alapján jelennek meg. -------------------- Defining agricultural enterprise (farm) raises many problems not only from economic but also from a legal viewpoint. Even among professionals definitions of agricultural enterprise according to sum of objects versus organizational forms are mixed. The EU law considers agricultural enterprise as a distinct legal category and rests on the fact that member countries use a unified law to regulate frames of functioning of national farms. But strictly speaking this statement is true only for western states of the union. Although some elements of operation regulation are to be found in Hungarian law as well, they are related not to an abstract category of law but rather to concreat organizational forms of agricultural enterprises. Another feature of our agricultural law is that the different organizational forms occur not in a unified framework, rather in occasional regulations depending on jurisdiction of that time and regime.

A pénzstabilitás primátusa ma már elfogadott a nyugati közgazdasági gondolkodásban. A valutaleértékelés kétélű fegyver, csupán az elavult exportszerkezetet konzerválja, a hatékonysági korlátok puhítása révén. A magyar gazdaság importfüggősége technikai jellegű, ezért a leértékelés csupán inflációs nyomást eredményez. Az agrárszektor részére a forint gyengülése sokkal több negatívummal járhatna, mint pozitívummal. Emelkedne az import eszközök ára, a felpörgő infláció révén szűkülne a belső piac. --------------------- Establishment and sustaining of stability of currency is the task of issuing bank while with realizing other economic targets (e.g. growth, employment, equilibrium) are dealing government regulation and institutions. Dominance of currency stability among economic indicators is today an accepted principle in western economic philosophy. Currency devaluation cuts both ways conserving outdated structure of exports through alleviation efficiency constrains. Import-dependence of Hungarian economy has a technological character therefore devaluation lead merely to inflational shock. For the agricultural sector a devaluation may cause many more negative impacts than positive ones. In such a case prices of imported inputs would rise while through more expensive foodstuffs domestic demand would be reduced.

description: Stablecoins are one of the most widely capitalized type of cryptocurrency. However, their risks vary significantly according to their design and are often poorly understood. We seek to provide a sound foundation for stablecoin theory, with a risk-based functional characterization of the economic structure of stablecoins. First, we match existing economic models to the disparate set of custodial systems. Next, we characterize the unique risks that emerge in non-custodial stablecoins and develop a model framework that unifies existing models from economics and computer science. We further discuss how this modeling framework is applicable to a wide array of cryptoeconomic systems, including cross-chain protocols, collateralized lending, and decentralized exchanges. These unique risks yield unanswered research questions that will form the crux of research in decentralized finance going forward.
Dislocation dynamics in a dodecagonal quasiperiodic structure

description: We have developed a set of numerical tools for the quantitative analysis of defect dynamics in quasiperiodic structures. We have applied these tools to study dislocation motion in the dynamical equation of Lifshitz and Petrich [Phys. Rev. Lett. 79 (1997) 1261] whose steady state solutions include a quasiperiodic structure with dodecagonal symmetry. Arbitrary dislocations, parameterized by the homotopy group of the D-torus, are injected as initial conditions and quantitatively followed as the equation evolves in real time. We show that for strong diffusion the results for dislocation climb velocity are similar for the dodecagonal and the hexagonal patterns, but that for weak diffusion the dodecagonal pattern exhibits a unique pinning of the dislocation, reflecting its quasiperiodic nature.

description: Monitoring structural damage is extremely important for sustaining and preserving the service life of civil structures. While successful monitoring provides resolute and staunch information on the health, serviceability, integrity and safety of structures; maintaining continuous performance of a structure depends highly on monitoring the occurrence, formation and propagation of damage. Damage may accumulate on structures due to different environmental and human-induced factors. Numerous monitoring and detection approaches have been developed to provide practical means for early warning against structural damage or any type of anomaly. Considerable effort has been put into vibration-based methods, which utilize the vibration response of the monitored structure to assess its condition and identify structural damage. Meanwhile, with emerging computing power and sensing technology in the last decade, Machine Learning (ML) and especially Deep Learning (DL) algorithms have become more feasible and extensively used in vibration-based structural damage detection with elegant performance and often with rigorous accuracy. While there have been multiple review studies published on vibration-based structural damage detection, there has not been a study where the transition from traditional methods to ML and DL methods are described and discussed. This paper aims to fulfill this gap by presenting the highlights of the traditional methods and provide a comprehensive review of the most recent applications of ML and DL algorithms utilized for vibration-based structural damage detection in civil structures.

description: Procedures for time-ordering the covariance function, as given in a previous paper (K. Kiyani and W.D. McComb Phys. Rev. E 70, 066303 (2004)), are extended and used to show that the response function associated at second order with the Kraichnan-Wyld perturbation series can be determined by a local (in wavenumber) energy balance. These time-ordering procedures also allow the two-time formulation to be reduced to time-independent form by means of exponential approximations and it is verified that the response equation does not have an infra-red divergence at infinite Reynolds number. Lastly, single-time Markovianised closure equations (stated in the previous paper above) are derived and shown to be compatible with the Kolmogorov distribution without the need to introduce an ad hoc constant.

Új módszerek, a gyakorlati képzés előtérbe helyezése, megfelelő motivációs rendszer segíthet a kialakult helyzeten. A BSc-képzési rendszer a három év alatt nem ad lehetőséget az elmélyültebb elméleti felkészülésre, ugyanakkor a félév szakmai gyakorlat sem nyújt elegendő szakmai felkészültséget, munkavégzésre alkalmas jártasságot. Mindezek miatt szükséges a képzés átgondolása, a gyakorlati képzés erősítése, a szakmai háttér minimumának biztosítása. ------------------------ Knowledge-based and competitive economies raise high demands for education. Experts of today can only be successful if they undertake that lifelong learning will be a principle of planning and accomplishing of their profession. It can be observed that popularity of agricultural education has decreased because of low respect and salary of experts as well as of unfavorable publicity of their work. The preseent education has too many branches. Due to massifi cation of education and lower level of secondary school studies there is somewhat inferior quality among people choiceing a career. New teaching methods, preference of practical education and a proper system of motivations can help in this situation. The present BSc education does not make possible deeper theoretical studies during the three years, neither offers the half-year practical training enough preparedness and skills for doing the work. Therefore it is necessary to reconsider the present educational system, strengthening training of practical nature and requiring a minimum level of knowledge from beginners.
Relaxation measurements in the regime of the second magnetization peak in Nb films

description: We report on magnetic measurements as a function of field, temperature and time (relaxation) in superconducting Nb films of critical temperature Tc = 9.25 K. The magnetic measurements as a function of field exhibited a second magnetization peak (SMP) which in general is accompanied by thermomagnetic instabilities (TMIs). The lines where the SMP occurs and where the first flux jump in the virgin magnetization curves is observed, end at a characteristic point (To,Ho)=(7.2 K,80 Oe). Relaxation measurements showed that for TTo=7.2 K both Uo and S present a conventional monotonic behavior. These results indicate that the SMP behavior observed in our Nb films is promoted by the anomalous relaxation of the magnetization.

description: With the evolution of generative linguistic steganography techniques, conventional steganalysis falls short in robustly quantifying the alterations induced by steganography, thereby complicating detection. Consequently, the research paradigm has pivoted towards deep-learning-based linguistic steganalysis. This study offers a comprehensive review of existing contributions and evaluates prevailing developmental trajectories. Specifically, we first provided a formalized exposition of the general formulas for linguistic steganalysis, while comparing the differences between this field and the domain of text classification. Subsequently, we classified the existing work into two levels based on vector space mapping and feature extraction models, thereby comparing the research motivations, model advantages, and other details. A comparative analysis of the experiments is conducted to assess the performances. Finally, the challenges faced by this field are discussed, and several directions for future development and key issues that urgently need to be addressed are proposed.

description: The Lazarus project was designed to make the most of limited 3D binary black-hole simulations, through the identification of perturbations at late times, and subsequent evolution of the Weyl scalar $Ψ_4$ via the Teukolsky formulation. Here we report on new developments, employing the concept of the ``quasi-Kinnersley'' (transverse) frame, valid in the full nonlinear regime, to analyze late-time numerical spacetimes that should differ only slightly from Kerr. This allows us to extract the essential information about the background Kerr solution, and through this, to identify the radiation present. We explicitly test this procedure with full numerical evolutions of Bowen-York data for single spinning black holes, head-on and orbiting black holes near the ISCO regime. These techniques can be compared with previous Lazarus results, providing a measure of the numerical-tetrad errors intrinsic to the method, and give as a by-product a more robust wave extraction method for numerical relativity.

description: We present a thorough investigation of nonstabilizerness - a fundamental quantum resource that quantifies state complexity within the framework of quantum computing - in a one-dimensional U(1) lattice gauge theory. We show how nonstabilizerness is always extensive with volume, and has no direct relation to the presence of critical points. However, its derivatives typically display discontinuities across the latter: This indicates that nonstabilizerness is strongly sensitive to criticality, but in a manner that is very different from entanglement (that, typically, is maximal at the critical point). Our results indicate that error-corrected simulations of lattice gauge theories close to the continuum limit have similar computational costs to those at finite correlation length and provide rigorous lower bounds for quantum resources of such quantum computations.

Rotation curve mass modeling of disk galaxies
Creators: name: Dutton, Aaron Ambrose
Publisher: name: University of British Columbia
Year: 2009

description: The standard Cold Dark Matter (CDM) model for cosmological structure formation has been remarkably successful in explaining the observed large scale structure of the universe. At the scale of individual galaxies, however, CDM faces serious challenges; one of these is the apparent discrepancy between the steep density profiles found in cosmological N-body simulations and the flatter density profiles inferred from optical rotation curves of low surface brightness galaxies. We have developed a new comprehensive rotation curve mass modeling decomposition code and tested it on 6 mass modeling standards, previously studied by Blais-Ouellette (2000). Our decompositions allow for all cosmologically-motivated types of halos, thin or thick disks, variable disk M/L ratio, adiabatic contraction of the dark halo, and non-spherical halos. We investigate the allowed range of inner density profile shapes as a function of disk M/L ratio. This program is being developed for an upcoming application to a new sample of 24 high and low surface brightness galaxies with wide-field optical/IR imaging and high-resolution long-slit Ho; rotation curves.
Microscopic description of fission in superheavy nuclei with the parametrization D1M$^{*}$ of the Gogny energy density functional

description: The constrained Hartree-Fock-Bogoliubov approximation, based on the recent parametrization D1M$^{*}$ of the Gogny energy density functional, is used to describe fission in 435 superheavy nuclei. The Gogny-D1M$^{*}$ parametrization is benchmarked against available experimental data on inner and second barrier heights, excitation energies of the fission isomers and half-lives in a selected set of Pu, Cm, Cf, Fm, No, Rf, Sg, Hs and Fl nuclei. Results are also compared with those obtained with the Gogny-D1M energy density functional. A detailed study of the minimal energy fission paths is carried out for isotopic chains with atomic numbers 100 $\le$ Z $\le$ 126 including very neutron-rich sectors up to around 4 MeV from the two-neutron driplines. Single-particle energies, ground state deformations, pairing correlations, two-nucleon separation energies and barrier heights are also discussed. In addition to fission paths, the constrained Hartree-Fock-Bogoliubov framework provides collective masses and zero-point quantum rotational and vibrational energies. Those quantities are building blocks within the Wentzel-Kramer-Brillouin formalism employed to evaluate the systematic of the spontaneous fission half-lives t$_\mathrm{SF}$. The competition between spontaneous fission and $α$-decay is studied, through the computation of the $α$-decay half-lives t$_\mathrmα$ using a parametrization of the Viola-Seaborg formula. From the comparison with the available experimental data and the results obtained with other theoretical approaches, it is concluded that D1M$^{*}$ represents a reasonable starting point to describe fission in heavy and superheavy nuclei.

description: A 2006-ban lefolytatott empirikus kutatás arra kereste a választ, hogy az agrárgazdaságban elhelyezkedni szándékozó fi atalok közül kinek van nagyobb esélye a szakmáján belüli helytállásra, melyek azok a tényezők, amelyek befolyásolják az eredményességet. Egyértelmű, hogy a fi atalok azon csoportjának nagyobb az esélye a helytállásra, akik kellőképpen elkötelezettek szakmájuk iránt, megfelelő mértékben motiváltak, nyitottak, illetve kreatívak. A kérdőíves felmérés rávilágított arra is, hogy a mintába került mezőgazdasági szakiskolai, szakközépiskolai tanulók, valamint agrár főiskolai/ egyetemi hallgatók szakmájuk iránti elkötelezettségét, hozzáállását a fi atalok családból hozott társadalmi, gazdasági és kulturális tőkéje, azaz az egyént jellemző szocioökonómiai faktorok erőteljesebben befolyásolják, mint az alapfokú oktatási intézmények. --------------------- During an empirical research in 2006 we tried to answer the question who among those young people, wanting a job in agriculture, will have better chance to fulfi l professional commitments and which are the factors infl uencing their successfulness. It has become unambiguosly clear that those have better chances who are properly lived up with commitments, are duly motivated as well as open and creative persons. The survey showed as well that professional binding of students of agricultural secondary schools and universities is stronger infl uenced by such socio-economic factors as human capital characterising individuals and originating from families than ground schools.
Extragalactic Background Light: new constraints from the study of the photon-photon absorption on blazar spectra

description: The study of the Extragalactic Background Light (EBL) is crucial to understand many astrophysical problems (as the formation of first stars, the evolution of galaxies and the role of dust emission). At present, one of the most powerful ways to put constraints on EBL is represented by the study of the photon-photon absorption on gamma-ray spectra of TeV blazars. Adopting this method, we found that, if the only contribution to the optical and Near Infrared (NIR) background is given by galaxies, the spectrum of the blazar H1426+428 cannot be fitted. To reproduce the observational data of H1426+428 a Near Infrared excess with respect to galaxy counts is required, with amplitude consistent with both the Matsumoto et al. (2000) data with Kelsall's model of zodiacal light (ZL) subtraction and the DIRBE data with Wright's model of ZL subtraction. The derived constraints on the optical EBL are weaker, because the experimental errors on blazar data are still bigger than the differences among various optical EBL models. In the mid-infrared the SPITZER measurement at 24 micron provides the best fit of the blazar spectrum.

description: In this article we review recent theoretical and experimental developments on multilongitudinal-mode emission in ring cavity lasers, paying special attention to class B lasers. We consider both homogeneously and inhomogeneously broadened amplifying media as well as the limits of small and large cavity losses (i.e., we treat cases within and outside the uniform field limit approximation). In particular we discuss up to what extent the experimental observations of self-mode locking in erbium-doped fiber lasers carried out in recent years are a manifestation of the Risken-Nummedal-Graham-Haken instability.

Stability of Pinned Surface Nanobubbles Against Expansion: Insights from Theory and Simulation

description: While growth and dissolution of surface nanobubbles has been widely studied in recent years, their stability under pressure changes or a temperature increase has not received the same level of scrutiny. Here, we present theoretical predictions based on classical theory for pressure and temperature thresholds ($p_c$ and $T_c$) at which unstable growth occurs for the case of air nanobubbles on a solid surface in water. We show that bubbles subjected to pinning have much lower $p_c$ and higher $T_c$ compared to both unpinned and bulk bubbles of similar size, indicating that pinned bubbles can withstand a larger tensile stress (negative pressure) and higher temperatures. The values of $p_c$ and $T_c$ obtained from many-body dissipative particle dynamics (MDPD) simulations of quasi-two-dimensional (quasi-2D) surface nanobubbles are consistent with the theoretical predictions, provided that the lateral expansion during growth is taken into account. This suggests that the modified classical thermodynamic description is valid for pinned bubbles as small as several nanometers. While some discrepancies still exist between our theoretical results and previous experiments, further experimental data is needed before a comprehensive understanding of the stability of surface nanobubbles can be achieved.

Abstract
Tremelimumab (tremelimumab-actl; Imjudo®) is a monoclonal antibody and immune checkpoint inhibitor (ICI) that blocks cytotoxic T lymphocyte-associated antigen-4 (CTLA-4). A single, priming dose of intravenous tremelimumab is used in combination with durvalumab, an ICI that blocks programmed cell-death ligand 1, in a regimen known as STRIDE (Single Tremelimumab Regular Interval Durvalumab). STRIDE is approved for the treatment of adults with unresectable hepatocellular carcinoma (HCC) in the USA and Japan and for the first-line treatment of adults with advanced or unresectable HCC in Europe. In the phase III HIMALAYA trial, STRIDE significantly improved overall survival (OS) compared with sorafenib in adults with unresectable HCC and no prior systemic therapy. A higher proportion of STRIDE versus sorafenib recipients had an objective response to treatment. The OS benefit associated with STRIDE was sustained with 4 years’ follow-up. STRIDE had a manageable safety profile that differed from that of sorafenib. Grade 3 or 4 treatment-related adverse events occurred in a lower proportion of STRIDE versus sorafenib recipients. Based on the available evidence, tremelimumab used as part of the STRIDE regimen is a valuable first-line agent that expands the treatment options available to patients with advanced or unresectable HCC.

Entanglement in SO(3)-invariant bipartite quantum systems

description: The structure of the state spaces of bipartite (N tensor N) quantum systems which are invariant under product representations of the group SO(3) of three-dimensional proper rotations is analyzed. The subsystems represent particles of arbitrary spin j which transform according to an irreducible representation of the rotation group. A positive map theta is introduced which describes the time reversal symmetry of the local states and which is unitarily equivalent to the transposition of matrices. It is shown that the partial time reversal transformation theta_2 = (I tensor theta) acting on the composite system can be expressed in terms of the invariant 6-j symbols introduced by Wigner into the quantum theory of angular momentum. This fact enables a complete geometrical construction of the manifold of states with positive partial transposition and of the sets of separable and entangled states of (4 tensor 4) systems. The separable states are shown to form a three-dimensional prism and a three-dimensional manifold of bound entangled states is identified. A positive maps is obtained which yields, together with the time reversal, a necessary and sufficient condition for the separability of states of (4 tensor 4) systems. The relations to the reduction criterion and to the recently proposed cross norm criterion for separability are discussed.

description: Let $E$ be an elliptic curve defined over $\mathbb{Q}$ with good ordinary reduction at a prime $p\geq 5$, and let $F$ be an imaginary quadratic field. Under appropriate assumptions, we show that the Pontryagin dual of the fine Mordell-Weil group of $E$ over the $\mathbb{Z}_p^2$-extension of $F$ is pseudo-null as a module over the Iwasawa algebra of the group $\mathbb{Z}_p^2$.
A Generalization of the Kramers-Kronig Relations for Linear Time-Varying Media

description: We explore the mathematical theory to rigorously describe the response of media with linear time-varying, generally dispersive, electromagnetic constitutive parameters. We show that even when the temporal inhomogeneity takes place on a time scale comparable or shorter than the driving fields' time period, one can still define a physically meaningful time-varying dispersion. Accordingly, a generalized set of Kramers-Kronig relations is investigated to link the real and imaginary parts of the time-varying frequency-dispersive spectra characterizing the medium's constitutive response. Among others, we study the case of a Lorentzian dielectric response with time-varying volumetric density of polarizable atoms and present the varying circuital equivalents of the governing differential equation, which in turn allow us to use the notion of generalized time-varying impedances/admittances of a time-dependent resistor, inductor and capacitor.

description: Cet article entreprend une analyse théorique approfondie des modèles de gestion de crise existants, en mettant particulièrement l'accent sur leur applicabilité aux petites et moyennes entreprises (PME). L'objectif de l’article vise à explorer les différentes approches théoriques qui se présentent dans la littérature pour appréhender et traiter les crises organisationnelles. À travers cette revue critique, l'article identifie les lacunes et les limitations inhérentes aux modèles existants, soulignant les défis spécifiques auxquels les PME sont confrontées lors de situations de crise. En réponse à ces constats, l'article propose un modèle de gestion de crise spécifiquement adapté aux PME, s'appuyant sur des concepts théoriques robustes et illustrant son applicabilité à travers des exemples concrets. L'article cherche ainsi à combler un vide dans la recherche en gestion de crise, en offrant une approche théoriquement informée et directement applicable aux besoins des petites et moyennes entreprises. Cette contribution propose des perspectives novatrices et pratiques pour une gestion efficace des crises dans le contexte spécifique des PME.
