description: Hollow core fibers are considered as promising candidates to deliver intense temporally overlapping picosecond pulses in applications such as stimulated Raman scattering (SRS) microscopy and endoscopy because of their inherent low nonlinearity compared to solid-core silica fibers. Here we demonstrate that, contrary to prior assumptions, parasitic signals are generated in Kagomé lattice hollow core fibers. We identify the origin of the parasitic signals as an interplay between the Kerr nonlinearity of air and frequency-dependent fiber losses. Importantly, we identify the special cases of experimental parameters that are free from parasitic signals, making hollow core fibers ideal candidates for noise-free SRS microscopy and endoscopy.

description: We prove that the dynamical system charaterized by the Hamiltonian $ H = λN \sum_{j}^{N} p_j + μ\sum_{j,k}^{N} {{(p_j p_k)}^{1\over 2}} \{ cos [ ν( q_j - q_k)] \} $ proposed and studied by Calogero [1,2] is equivalent to a system of {\it non-interacting} harmonic oscillators. We find the explicit form of the conserved currents which are in involution. We also find the action-angle variables and solve the initial value problem in simple form.

description: We present a scheme to reconstruct the quantum state of a field prepared inside a lossy cavity at finite temperature. Quantum coherences are normally destroyed by the interaction with an environment, but we show that it is possible to recover complete information about the initial state (before interaction with its environment), making possible to reconstruct any $s$-parametrized quasiprobability distribution, in particular, the Wigner function.

description: Mathematical expressions can be represented as a tree consisting of terminal symbols, such as identifiers or numbers (leaf nodes), and functions or operators (non-leaf nodes). Expression trees are an important mechanism for storing and processing mathematical expressions as well as the most frequently used visualization of the structure of mathematical expressions. Typically, researchers and practitioners manually visualize expression trees using general-purpose tools. This approach is laborious, redundant, and error-prone. Manual visualizations represent a user's notion of what the markup of an expression should be, but not necessarily what the actual markup is. This paper presents VMEXT - a free and open source tool to directly visualize expression trees from parallel MathML. VMEXT simultaneously visualizes the presentation elements and the semantic structure of mathematical expressions to enable users to quickly spot deficiencies in the Content MathML markup that does not affect the presentation of the expression. Identifying such discrepancies previously required reading the verbose and complex MathML markup. VMEXT also allows one to visualize similar and identical elements of two expressions. Visualizing expression similarity can support support developers in designing retrieval approaches and enable improved interaction concepts for users of mathematical information retrieval systems. We demonstrate VMEXT's visualizations in two web-based applications. The first application presents the visualizations alone. The second application shows a possible integration of the visualizations in systems for mathematical knowledge management and mathematical information retrieval. The application converts LaTeX input to parallel MathML, computes basic similarity measures for mathematical expressions, and visualizes the results using VMEXT.

Weighted distances in scale-free configuration models

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: In this paper we study first-passage percolation in the configuration model with empirical degree distribution that follows a power-law with exponent $τ\in (2,3)$. We assign independent and identically distributed (i.i.d.)\ weights to the edges of the graph. We investigate the weighted distance (the length of the shortest weighted path) between two uniformly chosen vertices, called typical distances. When the underlying age-dependent branching process approximating the local neighborhoods of vertices is found to produce infinitely many individuals in finite time -- called explosive branching process -- Baroni, Hofstad and the second author showed that typical distances converge in distribution to a bounded random variable. The order of magnitude of typical distances remained open for the $τ\in (2,3)$ case when the underlying branching process is not explosive. We close this gap by determining the first order of magnitude of typical distances in this regime for arbitrary, not necessary continuous edge-weight distributions that produce a non-explosive age-dependent branching process with infinite mean power-law offspring distributions. This sequence tends to infinity with the amount of vertices, and, by choosing an appropriate weight distribution, can be tuned to be any growing function that is $O(\log\log n)$, where $n$ is the number of vertices in the graph. We show that the result remains valid for the the erased configuration model as well, where we delete loops and any second and further edges between two vertices.

description: In the first part of this paper we present a theory of proof nets for full multiplicative linear logic, including the two units. It naturally extends the well-known theory of unit-free multiplicative proof nets. A linking is no longer a set of axiom links but a tree in which the axiom links are subtrees. These trees will be identified according to an equivalence relation based on a simple form of graph rewriting. We show the standard results of sequentialization and strong normalization of cut elimination. In the second part of the paper we show that the identifications enforced on proofs are such that the class of two-conclusion proof nets defines the free *-autonomous category.

description: No abstracts are to be cited without prior reference to the author.This contribution describes and analyze a NPZDF-model, which couples interactively a biogeochemical and a fish production model. The Baltic Sea is chosen as an example system, where the bulk fish dynamics can be represented by two prey species (sprat and herring) and one predator (cod). The linkage of the model components is established through feeding of prey fish on zooplankton and recycling of fish biomass to nutrients and detritus. The fish dynamics is driven by size dependent predator-prey interactions, reproduction and mortality. A challenge is the quantitative description of the multitude of processes involved. The model formulation is constraint by strict mass conservation. Two examples of experimental runs over 40 years are discussed: One scenario displays the catches over the time period of the years from 1960 to 2000 with increasing and declining cod catches. The second scenario indicates how slight adjustments of fishery rates could change the time development of catches toward a sustainable use of the resources

description: The constraint structure of 2D-gravity with the Weyl and area-preserving diffeomorphism invariances is analysed in the ADM formulation. It is found that when the area-preserving diffeomorphism constraints are kept, the usual conformal gauge does not exist, whereas there is the possibility to choose the so-called ``quasi-light-cone'' gauge, in which besides the area-preserving diffeomorphism invariance, the reduced Lagrangian also possesses the SL(2,R) residual symmetry. The string-like approach is applied to quantise this model, but a fictitious non-zero central charge in the Virasoro algebra appears. When a set of gauge-independent SL(2,R) current-like fields is introduced instead of the string-like variables, a consistent quantum theory is obtained.

Massive spin-2 particles in a curved background via a nonsymmetric tensor

description: Massive spin-2 particles has been a subject of great interest in current research. If the graviton has a small mass, the gravitational force at large distances decreases more rapidly, which could contribute to explain the accelerated expansion of the universe. The massive spin-2 particles are commonly described by the known Fierz-Pauli action which is formulated in terms of a symmetric tensor $h_{μν}=h_{νμ}$. However, the Fierz-Pauli theory is not the only possible description of massive spin-2 particles via a rank-2 tensor. There are other two families of models $\mathcal{L}(a_1)$ and $\mathcal{L}_{nFP}(c)$, where $a_1$ and $c$ are real arbitrary parameters, which describe massive particles of spin-2 in the flat space via a nonsymmetric tensor $e_{μν}\neq e_{νμ}$. In the present work we derive Lagrangian constraints stemming from $\mathcal{L}(a_1)$ and $\mathcal{L}_{nFP}(c)$ in curved backgrounds with nonminimal couplings which are analytic functions of $m^2$. We show that the constraints lead to a correct counting of degrees of freedom if nonminimal terms are included with fine tuned coefficients and the background space is of the Einstein type, very much like the Fierz-Pauli case. We also examine the existence of local symmetries.

description: No abstracts are to be cited without prior reference to the author.The Gulf of St. Lawrence is a summer feeding ground for the blue whale and other marine mammal species. Blue whale (Balaenoptera musculus) sightings in the northern part of the gulf have declined since the early 1990s, while the number of humpback whales (Megaptera novaeangliae) has increased since then. Over the same period, abundance of many Atlantic cod (Gadus morhua) and groundfish stocks in the Northwest Atlantic declined to low levels due to overfishing. With this decrease in biomass, the ensuing predation pressure on small pelagic fishes (capelin (Mallotus villosus) and Atlantic herring (Clupea harengus)) was quantitatively lower and could have led to an increase in their abundance and geographical distribution throughout the Gulf of St. Lawrence in the 1990s. Blue whales are specialists, feeding only on krill (zooplankton). Consequently, any increase in the capelin population, which mainly feed on zooplankton, would amplify potential competition with the blue whale for the same resource. However, the more opportunistic humpback whales, which target both zooplankton and fish, might be favored by this pattern, thus explaining their increased abundance. All these findings support the assumption that a striking change in the ecosystem food web could explain the observed variations in distribution and abundance of rorquals in this region.
Pseudoparticle Multipole Method: A Simple Method to Implement High-Accuracy Treecode
Creators: name: Kawai, Atsushi
name: Makino, Junichiro
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: In this letter we describe the pseudoparticle multipole method (P2M2), a new method to express multipole expansion by a distribution of pseudoparticles. We can use this distribution of particles to calculate high order terms in both the Barnes-Hut treecode and FMM. The primary advantage of P2M2 is that it works on GRAPE. GRAPE is a special-purpose hardware for the calculation of gravitational force between particles. Although the treecode has been implemented on GRAPE, we could handle terms only up to dipole, since GRAPE can calculate forces from point-mass particles only. Thus the calculation cost grows quickly when high accuracy is required. With P2M2, the multipole expansion is expressed by particles, and thus GRAPE can calculate high order terms. Using P2M2, we implemented an arbitrary-order treecode on GRAPE-4. Timing result shows GRAPE-4 accelerates the calculation by a factor between 10 (for low accuracy) to 150 (for high accuracy). Even on general-purpose programmable computers, our method offers the advantage that the mathematical formulae and therefore the actual program is much simpler than that of the direct implementation of multipole expansion.

Approximate Discrete Probability Distribution Representation using a Multi-Resolution Binary Tree

description: Computing and storing probabilities is a hard problem as soon as one has to deal with complex distributions over multiple random variables. The problem of efficient representation of probability distributions is central in term of computational efficiency in the field of probabilistic reasoning. The main problem arises when dealing with joint probability distributions over a set of random variables: they are always represented using huge probability arrays. In this paper, a new method based on binary-tree representation is introduced in order to store efficiently very large joint distributions. Our approach approximates any multidimensional joint distributions using an adaptive discretization of the space. We make the assumption that the lower is the probability mass of a particular region of feature space, the larger is the discretization step. This assumption leads to a very optimized representation in term of time and memory. The other advantages of our approach are the ability to refine dynamically the distribution every time it is needed leading to a more accurate representation of the probability distribution and to an anytime representation of the distribution.

description: No abstracts are to be cited without prior reference to the author.Here we present a new technique to study life history variation when only length distributions of populations are known. Shape of length distribution in a population is to a significant extent determined by the degree to which an average individual approaches its asymptotic maximum size. Statistically, the shape of a length can be characterised by its skewness, measuring the degree of symmetry in the distribution. Positive skew (long right tail) in a length distribution suggests that relative few individuals survive long enough to approach asymptotic size in a population, whereas the opposite is true for negative skew (long left tail). With a simple model of age-size dynamics in a population showing indeterminate growth, we show that skewness is strongly correlated with the ratio between mortality rate and the growth parameter k in the von Bertalanffy growth model; this ratio is a dimensionless number that is one of Beverton’s ‘life history statics’. We demonstrate the new technique with data from deep-pelagic fishes collected during the 2004 Mar-Eco expedition along the northern MidAtlantic Ridge

description: А. П. Огурцов работал в то время, когда изменилось отношение философии не только к естествознанию, но и к исторической науке. Философия истории из размышления о смысле истории, историчности человеческого бытия, типах культуры и социально-историческом развитии превратилась, особенно в американской философии, в философию исторической науки. Ее основной интерес заключается теперь не в проблемах исторического бытия, а в проблемах методологии исторического знания, в анализе способов построения теории, методов проверки исторических обобщений. В центре внимания оказалась реконструкция деятельности историка (роли эмпирических фактов, характера исторического повествования, способов доказательства и обоснования выдвигаемых утверждений и пр.). Разделяя в определенном отношении позиции Ф. Ницше, Огурцов отстаивал идею свободы, дифференцирующую деятельность общества и отдельных индивидов в ходе истории, поставив одновременно проблему того, что oзначает термин «влияние» для современной философии и ее матричное онтологическое основание.

description: We study the effect of lesions on our four-electrode measurements of the ionic conductivity of (1 cm3) samples of human brain excised from patients undergoing pediatric epilepsy surgery. For most (about 94 %) samples the low-frequency ionic conductivity rises upon increasing the applied frequency. We attributed this behavior to the long-range (0.4 mm) diffusion of solvated sodium cations before encountering impenetrable blockages such as cell membranes, blood vessels and cell walls. By contrast, the low-frequency ionic conductivity of some (6 %) brain tissue samples falls with increasing applied frequency. We attribute this unusual frequency-dependence to the electric-field induced liberation of sodium cations from traps introduced by the unusually severe pathology observed in samples from these patients. Thus, the anomalous frequency-dependence of the ionic conductivity indicates trap-producing brain lesions.

Implications of the PSR 1257+12 Planetary System for Isolated Millisecond Pulsars

description: The first extrasolar planets were discovered in 1992 around the millisecond pulsar PSR 1257+12. We show that recent developments in the study of accretion onto magnetized stars, plus the existence of the innermost, moon-sized planet in the PSR 1257+12 system, suggest that the pulsar was born with approximately its current rotation frequency and magnetic moment. If so, this has important implications for the formation and evolution of neutron star magnetic fields as well as for the formation of planets around pulsars. In particular, it suggests that some and perhaps all isolated millisecond pulsars may have been born with high spin rates and low magnetic fields instead of having been recycled by accretion.

description: The quantum coherence of one dimensional planar spin models with the Dzyaloshinsky-Moriya interaction is investigated. The anisotropic XY model, the isotropic XX model and the transverse field model are studied in the large N-limit using the two qubit reduced density matrices and the two point correlation functions. From our investigations we find that the coherence as measured using the Jensen-Shannon divergence can be used to detect the quantum phase transitions and the quantum critical points. The derivative of coherence shows non-analytic behavior at the critical points leading to the conclusions that these transitions are of second order. Further we show that the presence of the Dzyaloshinsky-Moriya coupling suppresses the phase transition due to the residual ferromagnetism which is caused by spin canting.

description: Представление о времени в традиционных культурах отличается от современных представлений, доминирующих в науке. Традиция считает время циклическим и качественным, современная наука, напротив, линейным и количественным. Для индоиранской традиции свойственно утверждение об изначальном вечном и непостижимом принципе, из которого разворачивается наш мир, существующий во времени, в котором все меняется. В зороастризме вечный непостижимый и бесконечный Зерван Акарана отличен от «длинного» конечного времени Зервана Карана. Аналогично этому в индуизме Вишну-Пурана говорит об изначальном непостижимом Брахме, из которого Время-Кала развертывает весь проявленный мир двойственности. Циклы времени свойственны проявленному миру. Математизация времени, его измерение, создание календарей, помимо практических целей, преследовали прежде всего метафизические цели. Они символизировали устройство мира. Посредниками между изначальным принципом, вечным бесконечным Временем и человеческим масштабом времени являются космические циклы. По аналогии с ними понимается и логика истории. Современная идея всемирной истории связана с возникновением в новое время идеи линейного времени. Логика истории определена тем, что история всегда есть рассказ. Рассказ же имеет начало, середину и конец. Традиционные представления о рассказанных событиях носили символический и метафизический характер.
Development of genetically encoded sensors for real-time monitoring of GLP-1 dynamics in the paraventricular nucleus of the hypothalamus
Creators: name: Luo, Fang

Year: 2025

description: Glucagon-like peptide-1 (GLP-1) is a critical neuroendocrine signal involved in glucose homeostasis and appetite regulation. Here, we report the development of genetically encoded fluorescent GLP-1 sensors (GLP-1 RTGR) designed to monitor GLP-1 dynamics in real time within the paraventricular nucleus (PVN) of the hypothalamus in freely behaving mice. By engineering GLP-1 receptors fused to circularly permuted fluorescent proteins, we achieved highly specific and sensitive detection of endogenous GLP-1 release. In vitro, ex vivo, and in vivo validation confirmed that these sensors exhibit robust and selective responses, enabling precise spatiotemporal mapping of GLP-1 fluctuations. Fiber photometry measurements revealed dynamic GLP-1 signaling patterns that correlate with feeding states, increasing postprandially and potentially reflecting satiety signals. Furthermore, preproglucagon knockout models lacking endogenous GLP-1 showed disrupted feeding patterns, underscoring GLP-1’s role in appetite control. Using a moving average crossover analysis, we predicted feeding behavior from GLP-1 fluctuations with high accuracy. Our findings demonstrate that GLP-1 RTGR sensors provide a powerful tool for real-time neuropeptide imaging, offering new insights into the neuroendocrine mechanisms governing energy balance and highlighting potential targets for metabolic disorder therapies.

Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We show that the potential wells with a central spike V(x) = x^{10} + a x^8 + b x^6+ c x^4 + d x^2 + f/x^2 possess arbitrary finite multiplets of elementary exact bound states. The strong asymptotic growth of V(x) implies an ambiguity in the PT-symmetric quantization via complex boundary conditions but the three eligible recipes coincide at our exceptional solutions.

Temperature Anisotropy Relaxation of the One-Component Plasma

description: The relaxation rate of a Maxwellian velocity distribution function that has an initially anisotropic temperature $(T_\parallel \neq T_\perp)$ is an important physical process in space and laboratory plasmas. It is also a canonical example of an energy transport process that can be used to test theory. Here, this rate is evaluated using molecular dynamics simulations of the one-component plasma. Results are compared with the predictions of four kinetic theories; two treating the weakly coupled regime (1) the Landau equation, and (2) the Lenard-Balescu equation, and two that attempt to extend the theory into the strongly coupled regime (3) the effective potential theory and (4) the generalized Lenard-Balescu theory. The role of dynamic screening is studied, and is found to have a negligible influence on this transport rate. Oscillations and a delayed relaxation onset in the temperature profiles are observed at strong coupling, which are not described by the kinetic theories.

description: По мнению автора, целое истории, позволяющее ее помыслить и установить сущность, — не только интерпретации истории, но и исторический способ жизни личности и исторический способ существования культуры. Реальность истории смыкается в определенном смысле с настоящим; история не только действует на человека наподобие искусства, она опирается на исторические факты, разворачивает перед нами истории, ясные в событийном отношении, имеющие начало и конец, предъявляет нам знания о прошлом (в форме определенных версий, интерпретаций), полагает новую, историческую реальность в культуре. Вводится различение трех типов истории: «сюжетной», «прикладной» и «научной» («междисциплинарной»). С последним вариантом истории связан процесс концептуализации истории в философии и науке, который начинается еще в конце античной культуры и в Средние века, но по-настоящему набирает силу только в Новое время. Это не просто философское и научное осмысление исторических построений и объяснений, но и создание методологии истории и практики исторических исследований — собственно исторической науки. Сюжетная история как рассказ о прошедших событиях выступает в исторической науке только несущей эмпирической основой. В междисциплинарной истории главным выступает создание начал и идеальных объектов. С их помощью решаются теоретические и философские проблемы и задачи, которые были поставлены в ходе рефлексии по поводу событий сюжетной истории. На материале одного кейса анализируются особенности прикладной истории.
Post Inflationary Behaviour of String Moduli

description: We analyze the behaviour of moduli fields in string effective models between the end of inflation and reheating. The effective moduli potential during this era is derived for a class of simple models. We argue that this potential significantly stabilizes the modulus at its high energy minimum, if some restrictions on modular weights are met. Two mechanisms to further stabilize the moduli to their low energy minima are discussed explicitly: coinciding minima at a point of enhanced symmetry, and the smooth transition from high to low energy minimum by an effective mass term C^2 H^2. For both cases we present explicit examples, and C^2 is found to be O(10) at most. In addition, we show that during a smooth transition the reduction of the modulus amplitude strongly depends on the shape of the low energy potential.

description: В статье рассматривается сравнительно новая для нас тема политического нарциссизма. Явление, многим кажущееся по жизни хорошо знакомым и достаточно маргинальным, оказывается одной из фундаментальных проблем нашего времени — эпидемией нарциссизма, «чумой XXI века», психологическим ядром постмодерна. В политике это проблема отнюдь не только лидеров, страдавших более или менее деструктивной, а то и вовсе злокачественной патологией, но и масс, сознание и бессознательное которых фиксировано на грандиозности и всемогущественности политического целого. Нарциссизм компенсирует коммунальные комплексы, но при этом блокирует решение реальных жизненных проблем. То, что в знакомых мы воспринимаем лишь как забавную и в целом безобидную черту характера, в психоистории чревато трагедиями. Связь нарциссизма с влечением к смерти не придумана философами. И смерть Нарцисса от голода — не случайная деталь красивого мифа. Нарциссическое самолюбование целой страны — одурманенных людей и бессубъектных структур сознания — сопровождается развалом базовых систем жизнеобеспечения: экономики, технологий, инфраструктуры.
SLA-Based Coordinated Superscheduling Scheme and Performance for Computational Grids

description: The Service Level Agreement~(SLA) based grid superscheduling approach promotes coordinated resource sharing. Superscheduling is facilitated between administratively and topologically distributed grid sites by grid schedulers such as Resource brokers. In this work, we present a market-based SLA coordination mechanism. We based our SLA model on a well known \emph{contract net protocol}. The key advantages of our approach are that it allows:~(i) resource owners to have finer degree of control over the resource allocation that was previously not possible through traditional mechanism; and (ii) superschedulers to bid for SLA contracts in the contract net with focus on completing the job within the user specified deadline. In this work, we use simulation to show the effectiveness of our proposed approach.

Рассуждения о статье А. П. Огурцова «Поражение философии»

description: Даётся интерпретация тезисов, выдвинутых А. П. Огурцовым в статье «Поражение философии». В центре внимания — обсуждение утверждений автора об утрате философией судьбоносных целей и ценностей, что приводит к смене социальных приоритетов — место, ранее принадлежавшее философии, занимают религия и богословие. Эпоха Нового времени оказалась возможной благодаря изменению веры, вытеснению христианства в самых разных вариантах из центра социальной жизни на её периферию, инсталлированию в общественное сознание веры в автономную науку и философию. Причем автономность науки обеспечивалась философией как наукоучением, как опытом её (науки) самообоснования. Логика самообоснованного знания, не нуждавшаяся в различного рода религиозных авторитетах, как раз и была тем светом, который освещал путь человечества в будущее. Э. Гуссерль, как и А. П. Огурцов, свидетельствует об отказе от миссии науки быть факелом, освещающим дорогу человечеству, который наметился в начале XX века и проявился во всей своей очевидности к его концу. Кризис внутри философии оборачивается своеобразной идеологической контрреволюцией — религия возвращается на то социальное место, с которого её потеснили философия и наука в начале эпохи Нового времени.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Biodiversity can play an important role in the stability and resilience of an ecosystem when facing environmental changes or anthropogenic impacts. In addition to the fishery-induced collapse of cod and redfish, the last two decades have been characterized by a cooling of water masses in the Gulf of St. Lawrence. Historically the northwest of the Gulf was known to have a high fish egg and larval productivity due to hydrodynamic features. To assess changes in the ichthyoplankton community, we compared data from samplings carried out in spring in this region from 1985 to 1987 with data from spring 2005 to 2007. Significant differences in the ichthyoplankton assemblages between the two time periods were highlighted by multivariate analyses as well as differences in the assemblages between sampling times (May versus June). The results indicate that the total fish egg and larval abundance were lower in the 2000’s period than during the mid 1980’s. Eggs from the CHW (that includes cod) category that were the most abundant in the mid 1980’s are now replaced by H4B eggs. Although Ammodytes spp. remains one of the most frequent species, its abundance decreased and other species became more abundant (i.e., species from the Stichaeidae), while Sebastes spp. is no longer one of the top four dominant species. Others species also appeared recently in the 2000’s assemblages (i.e., Reinhardtius hippoglossoides). Our study provides much needed new information of current biodiversity and productivity of the fish community in the northwest Gulf of St. Lawrence and insights of its changes as influenced by environmental fluctuations
