description: Imagery to support a proposed VME based on high abundances of VME indicator taxa that fall within the range of previously registered VMEs. The site is off the east coast of Lambda Island, Melchior Islands, Western Antarctic Peninsula. Video imagery was taken via submersible deployed by Seabourn Venture crewed by scientist and volunteer citizen science pilots. Data on the relative percent cover of all VME indicator taxa was sourced and analysed in the same manner as VMEs added to CCAMLR’s registry in 2018 (SC-CCAMLR-XXXVII) and 2022 (SC-CCAMLR-41) using all data from WG-EMM-18/35, WG-EMM-22/34Rev1 and WG-EMM-22/46Rev1 for a direct comparison. The present site clusters with previously registered VMEs. The site supports many large hexactinellid sponges and small bamboo corals. Notable also, is the presence of the rare and little-known hydroid, Candelabrum sp. – a VME indicator taxa that is particularly vulnerable to fishing gear as they can extend metres into the water column.

Method step description: 

DaVinci Resolve 18 was used to combine separate files where necessary and for editing. 

Clean-up followed the same methodology as was used for analyzing the submarine footage for the successful nomination of VMEs in WG-EMM-22/46Rev1 to remove unusable sequences. For the Lambda Is footage that meant the removal of any sequences where the submersible was too far from the wall, where the visibility was poor and when the submersible was stationary. Footage from Dive A was the longest resulting video after the completion of this clean-up procedure (Table 1), thus it became the footage that was analysed.

Footage was color adjusted within DaVinci Resolve 18.

The analysis methodology also followed that which was used in WG-EMM-22/46Rev1. To compare the relative percent abundance of VME indicator taxa to that of non-VME taxa and bare substrate at the Lambda Is site, frames were exported at regular intervals (30 secs) beginning at 0:00.

The resulting series of images were then imported into the program PAPARA(ZZ)I (Marcon & Purser,  2017). Within this program images were further enhanced by adjusting brightness, contrast and gamma. As recommended by the authors, the usable area was then defined for each image allowing the exclusion of dark or blurred edges.

Once images were prepared in this way, an array of 100 random points was overlayed. Each point in each image was assigned one of three designations: VME indicator taxa, non-VME taxa or bare substrate.

This version contains frames (tif files) with area analyzed by PAPARA(ZZ)I boxed. This version is an updated version of https://doi.org/10.5281/zenodo.12179714

description: A disorder-order transition from amorphous carbon (aC) to layered amorphous graphene (LAG) has been predicted using ab-initio methods. Amorphous carbon at densities close to the graphitic density show a strong proclivity to layer in NVT simulations near 3000K . Our calculations have shown that graphitization is strongly dependent on the simulation temperature and is not observed under 2500K. The origin of such a disorder-order transition has been studied using various structural analyses. Each layer of LAG is a layer of amorphous graphene (aG) including pentagons and heptagons in addition to hexagons and the planes are separated by about 3.2A. LAG obtained from the NVT simulations were highly stable. The electronic charge density, especially for the pi and pi$^*$ states, was computed with the Hyed-Scuseria-Ernzerhof (HSE) hybrid functional and compared with crystalline graphite (cG). The impact of structural disorder has been studied in detail, especially the consequences of disorder to electronic transport.

description: Metal additive manufacturing is gaining broad interest and increased use in the industrial and academic fields. However, the quantification and commercialization of standard parts usually require extensive experiments and expensive post-characterization, which impedes the rapid development and adaptation of metal AM technologies. In this work, a similarity-based acceleration (S-acceleration) method for design of experiments is developed to reduce the time and costs associated with unveiling process-property (porosity defects) relationships during manufacturing. With S-acceleration, part semantic features from machine-setting parameters and physics-effects informed characteristics are explored for measuring mutual part similarities. A user-defined simplification rate of experiments is proposed to purposely remove redundant parts before conducting experiments printing without sacrificing information gain as original full factorial experiment design. This S-acceleration design of experiments is demonstrated on a Concept Laser M2 machine for the experimental plan of modeling relationships between process parameters and part porosity defects. The printed part has 2 mm diameter by 4 mm tall pin geometry considering variations in build location and orientation, laser settings and powder feedstock are held constant. In total, 242 parts are measured to create a ground truth data set of porosity levels by using X-ray tomography microscopy. The S-acceleration method is assessed for performance considering 40%, 50%, and 60% of user-defined experiment simplification rates. The repeated experiments are removed without ignoring the minority experiments outlier, assuring a similar process-property relation in the original experiment plan. The experiment number is significantly reduced based on part similarity with minimal compromise of model accuracy and obtained knowledge.

description: N fertilization and straw incorporation often disturb the soil and may affect nitrite oxidation (NO); however, the underlying mechanism remains unclear. Here, we collected soil samples through a 4-year field experiment including no N fertilization, normal N application, excess N application (EN), and EN plus straw incorporation (ES) treatments. We measured the community composition, abundance, and activity of Nitrobacter-like and Nitrospira-like nitrite-oxidizing bacteria (NOB). N application and straw incorporation significantly enhanced potential NO activity (PNO). PNO was affected by the abundance of Nitrobacter but not Nitrospira and the community compositions of both NOB. With increasing N application rate, Nitrobacter abundance increased from 1.0 to 11.8 × 104 copies g−1 dry weight soil, whereas Nitrospira abundance increased initially then subsequently decreased, ranged from 2.1 to 5.2 × 106 copies g−1 dry weight soil. Moreover, N application and straw incorporation markedly affected the NOB community composition. Soil pH and organic C were the key factors shaping the NOB community composition. Overall, N fertilization combined with straw incorporation can affect NO by altering the Nitrobacter abundance and NOB community composition. These findings expand our understanding of mechanisms underlying the effects of straw incorporation on nitrification, particularly under N enrichment.

description: Contrary to conventional frame-based imaging, event-based vision (EBV) or dynamic vision sensing (DVS) asynchronously records binary signals of intensity changes for given pixels with microsecond resolution. The present work explores the possibilities of harnessing the potentials of event-based vision for fluid flow measurement. The described implementations of event-based imaging velocimetry (EBIV) rely on the imaging small particles that are illuminated by a laser light sheet which is similar to classical two-dimensional, two-component (2d-2c) PIV with the difference that a continuously operating laser-light sheet is used without modulation of the laser or camera. The moving particles generate continuous time-stamped events on the detector that are later used to infer their velocity using patch-wise processing schemes. Two flow estimation algorithms are proposed; one uses a "motion compensation" that maximizes the local contrast, the other is based on a sum-of-correlations approach. The underlying motion detection schemes along with the complete absence of background signal allows straightforward retrieval of the events associated with individual particles thereby allowing the reconstruction of individual particle tracks. Alternatively, the event data can be processed with conventional PIV algorithms using images reconstructed from the event data stream. The concepts are demonstrated on simple flows in water and air.

description: We present general relativistic magnetohydrodynamic simulations of merging equal-mass, spinning black holes embedded in an equatorial thin slab of magnetized gas. We evolve black holes either non-spinning, with spins aligned to the orbital angular momentum, and with misaligned spins. The rest-mass density of the gas slab follows a Gaussian profile symmetric relative to the equatorial plane and it is initially either stationary or with Keplerian rotational support. As part of our diagnostics, we follow the accretion of matter onto the black hole horizons and the Poynting luminosity. Throughout the inspiral phase, the configurations with non-zero spins display modulations in the mass accretion rate that are proportional to the orbital frequency and its multiples. Our frequency analysis suggests that these modulations are influenced by the initial geometry and angular momentum of the gas distribution. In contrast to binary models evolved in the gas cloud scenario, we do not observe a significant increase in the mass accretion rate after the merger in any of our simulations. This observation brings attention to a potential link between the electromagnetic signatures of massive binary black hole mergers and the geometrical distribution of the surrounding gas. It also suggests the possibility of not detecting a peak luminosity at the time of merger in future electromagnetic observations.

description: Baetopus (Raptobaetopus) tenellus (Albarda, 1878)
This transpalaearctic species is rare within all areal. Larvae are evidently predaceous (Bauernfeind & Soldán 2012). One larva of B. tenellus (Fig. 10) was registered in Styr River (Figs 14, 15), the right tributary of the Prypyat’ River, at microhabitat with silted sand bottom and current velocity from 0.2 to 0.3 m /s. The additional parameters of waterbody in collecting place measured during the sampling were: water temperature 29°C, water hardness 259 ppm, pH 8.6. This is the first record of the genus Baetopus Keffermüller, 1960, as well as the species B. tenellus within Ukraine.

description: Different soil management strategies may either promote or degrade soil structure. This study aimed to test the Visual Evaluation of Soil Structure (VESS) method in a smallholder agroforestry system in the eastern Amazon. Three plots (P1, papaya field; P2, banana intercropped with cassava; P3, banana, cassava, and açaí), as well as an adjoining area under native vegetation (NV), were evaluated using VESS. Quantitative assessments of soil physical quality were also performed, including soil water retention curve (SWRC), bulk density (Bd), particle density (Pd), microporosity (Mi), macroporosity (Ma), total porosity (Tp), available water capacity (AWC), field capacity (FC), and permanent wilting point (PWP). The VESS scores in P2 (2.6) and P3 (1.8) were similar to NV (1.4), while P1 (2.8) had a poorer structure. P1 differed from the other plots, with lower Ma (0.05 m3 m−3) and Tp (0.39 m3 m−3), and higher Bd (1.57 Mg m−3), AWC (0.32 m3 m−3), and water retention at FC (θFC: 0.33 m3 m−3). VESS scores were significantly correlated with most quantitative measurements. These results indicate that VESS is effective to assess soil structure, providing a convenient strategy for soil structural quality assessment in smallholders from Amazon.

description: The value of spectral form factor at the origin, called level compressibility, is an important characteristic of random spectra. The paper is devoted to analytical calculations of this quantity for different random unitary matrices describing models with intermediate spectral statistics. The computations are based on the approach developed by G. Tanner in [J. Phys. A: Math. Gen. 34, 8485 (2001)] for chaotic systems. The main ingredient of the method is the determination of eigenvalues of a transition matrix whose matrix elements equal squared moduli of matrix elements of the initial unitary matrix. The principal result of the paper is the proof that the level compressibility of random unitary matrices derived from the exact quantisation of barrier billiards and consequently of barrier billiards themselves is equal to $1/2$ irrespectively of the height and the position of the barrier.

description: We solve the random energy model when the energies of the configurations take only integer values. In the thermodynamic limit, the average overlaps remain size dependent and oscillate as the system size increases. While the extensive part of the free energy can still be obtained by a standard replica calculation with one step replica symmetry breaking, it is no longer possible to recover the overlaps in this way. A possible way to adapt the replica approach is to allow the sizes of the blocks in the Parisi matrix to fluctuate and to take complex values.

description: Reflective practice is a key skill in many professions and is considered an essential attribute of healthcare practitioners. Healthcare students are often expected to develop reflection skills through their assignments, and this is frequently expected to occur with little explicit instruction, practice or guidance about how to reflect. Currently, there is limited guidance in the literature on how teachers can help students develop these reflective skills effectively. In this study, we describe a process for embedding reflective skills into a transition program for new healthcare students about to enter university. By allowing students to explore reflection through a method of self-discovery supported by peer discussion, we found that students were likely to recognise and value reflection as a learning tool (a concept we term “reflection for learning”). Additionally, these students were more likely to continue to practice reflection in their studies than students who had not participated in the training. In summary, this paper demonstrates that students are able to make meaningful deductions about reflective practice and their own learning through use of a basic framework in which to self-reflect, from the very start of their tertiary studies.

description: We investigate the strongly first-order electroweak phase transition using an effective field theoretical approach. The standard effective field theory with finite number truncation of higher dimensional operators fails in the typical parameter space where the strongly first-order phase transition is realized because it cannot describe the non-decoupling quantum effect of new physics beyond the standard model. To parameterize the non-decoupling quantum effect, we employ the nearly aligned Higgs effective theory in which the Higgs potential is parameterized by a Coleman-Weinberg like form. Extending this framework with finite temperature corrections, we study the parameter space for realizing the strongly first-order phase transition, and estimate the gravitational wave produced at the phase transition.

description: Some quantum information processing protocols necessitate quantum operations that are invariant under complex conjugation. In this study, we analyze the non-local resources necessary for implementing conjugation-symmetric measurements on multipartite quantum networks. We derive conditions under which a given multipartite conjugation can have locally implementable symmetric measurements. In particular, a family of numbers called the ``magic-basis spectrum'' comprehensively characterizes the local measurability of a given 2-qubit conjugation, as well as any other properties that are invariant under local unitary transformations. We also explore the non-local resources required for optimal measurements on known quantum sensor networks by using their conjugation symmetries as a guide.

description: The remarkable universality of the cuprate $T_c$ dome suggests a very fundamental unifying principle. Moreover, the superconducting gap is known to persist above $T_c$ in the pseudogap phase of all cuprates. So, contrary to BCS, the gap cannot be the order parameter of the transition. In this work, we show that both the $T_c$-dome and the pseudogap line $T^*(p)$ arise from a unique and identifiable principle: the interaction of localized `pairons' on an antiferromagnetic square lattice. The topological constraints on such preformed pairons give rise to both the $T_c$ dome and the pairing energy {\it simultaneously}. It also provides a natural explanation for the critical doping points of the phase diagram. The model matches perfectly both the $T^*$ and $T_c$ experimental lines, with only one adjustable parameter.

description: Brachycercus harrisella Curtis, 1834
This species is widely distributed all over Europe, but rare in the Mediterranean area (Bauernfeind & Soldán 2012). In Ukraine B. harrisella also belongs to rare species; it was known only from the Dnister River, middle and low courses of the Desna River, upper course of the Dnipro River (Polishchuk 1964; Invertebrates… 1989; Nedostup 1994). We registered larvae of this species (Fig. 13) at different points of the Stvyga River within Rivne Region (Figs 14, 16).
Habitat: In all sampling places the river had the moderate current velocity (from less than 0.05 to 0.5 m /s) and the bottom of sand or silted sand (Fig. 16). The main number of larvae was collected in microhabitats with accumulations of detritus and current velocity 0.1–0.3 m /s. Additional parameters of waterbody in sampling places were: water temperature 21–22°C, water hardness 47–49 ppm, pH 7.4–7.5.

Glueball-Meson Mixing In Holographic QCD

description: Top-down holographic QCD models often work in the "probe" (or "quenched") limit, which assumes that the number of colors is much greater than the number of flavors. Relaxing this limit is essential to a fuller understanding of holography and more accurate phenomenological predictions. In this work, we focus on a mixing of glueball and meson mass eigenstates that arises from the DBI action as a finite Nf/Nc effect. For concreteness, we work in the Witten-Sakai-Sugimoto model, and show that this mixing must be treated in conjunction with the backreaction of the flavor branes onto the background geometry. Including the backreaction with the simplification that it is "smeared out" over the compact transverse direction, we derive a corrected effective action for the vector glueball and scalar states. Along the way, we observe a Stueckelberg-like mechanism that restores translation invariance in the transverse direction. We also derive a general technique, that lends itself easily to numerics, for finding mass eigenstates of Lagrangians with vector-scalar mixing. We then calculate the first order corrections to the mass spectra of both the vector and scalar particles, and show that the term that explicitly mixes vector and scalar states is the most significant correction to the masses of low-lying scalar mesons.

description: Siphlonurus aestivalis Eaton, 1903
This species is rare in Ukraine. Previously it was known only from one point in Chernivtsi Region at the vicinity of Berehomet settlement (Martynov 2013). We registered S. aestivalis in two localities at the Desna River within Chernihiv Region (Figs 14, 17).
Habitat: In Chernivtsi Region larvae were collected at limnocrene (shallow draw-well). In contrast, in Chernihiv Region larvae of the species were collected in small well-warmed bay and the standing area along the bank of the Desna River. These microhabitats were located within the potamal zone of the river and characterized by the silted bottom densely overgrown with Agrostis stolonifera Linnaeus, 1753 (Poaceae) (Fig. 17). Population density of S. aestivalis in grass thickets at the bay of the Desna River was 117 specimens /m 2. Additional parameters of waterbody in sampling places were: water temperature 18°C, water hardness 160–181 ppm, pH 8.7–9.0.
Material: Ukraine, Chernihiv Region: 232 larvae, vicinity of Prydesnyans’ke village, bay of Desna River, 51.613417, 33.007583, h – 118 m a.s.l., Martynov A.

description: The landscape of computational modeling in cancer systems biology is diverse, offering a spectrum of models and frameworks, each with its own trade-offs and advantages. Ideally, models are meant to be useful in refining hypotheses, to sharpen experimental procedures and, in the longer run, even for applications in personalized medicine. One of the greatest challenges is to balance model realism and detail with experimental data to eventually produce useful data-driven models. We contribute to this quest by developing a transparent, highly parsimonious, first principles silico model of a growing avascular tumor. We initially formulate the physiological considerations and the specific model within a stochastic cell-based framework. We next formulate a corresponding mean-field model using partial differential equations which is amenable to mathematical analysis. Despite a few notable differences between the two models, we are in this way able to successfully detail the impact of all parameters in the stability of the growth process and on the eventual tumor fate of the stochastic model. This facilitates the deduction of Bayesian priors for a given situation, but also provides important insights into the underlying mechanism of tumor growth and progression. Although the resulting model framework is relatively simple and transparent, it can still reproduce the full range of known emergent behavior. We identify a novel model instability arising from nutrient starvation and we also discuss additional insight concerning possible model additions and the effects of those. Thanks to the framework's flexibility, such additions can be readily included whenever the relevant data become available.

description: We consider an extension of the Standard Model that accounts for the muon $g-2$ tension and neutrino masses and study in detail dark matter phenomenology. The model under consideration includes a WIMP and a FIMP scalar dark matter candidates and thus gives rise to two-component dark matter scenarios. We discuss different regimes and mechanisms of production, including the novel freeze-in semi-production, and show that the WIMP and FIMP together compose the observed relic density today. The presence of the extra scalar fields allows phase transitions of the first order. We examine the evolution of the vacuum state and discuss stochastic gravitational wave signals associated with the first-order phase transition. We show that the gravitational wave signals may be probed by future gravitational wave experiments which may serve as a complementary detection signal.

Metreletus balcanicus

description: Metreletus balcanicus (Ulmer, 1920)
Metreletus balcanicus is a rare stenobiotic species distributed in South-Central Europe (Soldán & Zahrádková 2000). For the first time it was given for Ukraine from Kharkiv Region (Martynov 2011): this is the most eastern known point within the whole species distribution. Present research revealed a new locality of M. balcanicus in Ukraine, at Zakarpattia Region (Figs 14, 18).
Habitat: In Kharkiv Region M. balcanicus inhabits the hipopotamal zone of middle-sized Lukonovakha River that dries up periodically. In Zakarpattia Region this species was found in the Salva River, which looked like a cascade of puddles connected with shallow streams in May, 2017 when material was collected (Fig. 18). Additional parameters of waterbody in sampling place were: water temperature 14°C, water hardness 52 ppm, pH 7.1. All larvae (Fig. 11) were gathered from stones or silted stones at the bottom and roots in puddles. We had also found the fresh exuvia and imagoes (Fig. 12) that confirms the fact of emergence for M. balcanicus at this period.
Material: 16 larvae, 4 exuviae, 9 imagoes (3♂ + 6♀), Ukraine, Zakarpattia Region, territory of Bukove village, Salva River, 48.198433, 23.090850, h – 181 m a.s.l., Martynov A. V. leg., 11.05.2017 – IN Zkp 10 Metbal /1–4.
Recommendations for conservation: Metreletus balcanicus is rare and stenobiotic in Ukraine and whole its areal, it has the restricted distribution within Ukraine; therefore we think that the species should be considered as perspective for including in the Red Data Book of Ukraine. Detailed investigation (also genetic affinity to other populations) of Ukrainian populations of M. balcanicus continues.

description: We develop a framework to determine the complete statistical behavior of a fundamental quantity in the theory of random walks, namely, the probability that $n_1$, $n_2$, $n_3$, . . . distinct sites are visited at times $t_1$, $t_2$, $t_3$, ... . From this multiple-time distribution, we show that the visitation statistics of 1d random walks are temporally correlated and we quantify the non-Markovian nature of the process. We exploit these ideas to derive unexpected results for the two-time trapping problem and also to determine the visitation statistics of two important stochastic processes, the run-and-tumble particle and the biased random walk.

description: We present theoretical results for the sensitivity of charm Yukawa coupling measurements in future high-luminosity LHC runs in three channels: Vector Boson Fusion (VBF), W Higgs-strahlung and Z Higgs-strahlung production of a Higgs boson and its subsequent decay into charm quarks. To reduce the overwhelmingly large backgrounds and to reduce false positives, we apply a set of simple kinematic and jet feature cuts and feed neural network data structures of three types; jet features, jet images and particle level features. To facilitate straightforward comparison with experimental studies, we express our results in terms of signal strengths.
