description: We study the relativistic version of Schrödinger equation for a point particle in 1-d with potential of the first derivative of the delta function. The momentum cutoff regularization is used to study the bound state and scattering states. The initial calculations show that the reciprocal of the bare coupling constant is ultra-violet divergent, and the resultant expression cannot be renormalized in the usual sense. Therefore a general procedure has been developed to derive different physical properties of the system. The procedure is used first on the non-relativistic case for the purpose of clarification and comparisons. The results from the relativistic case show that this system behaves exactly like the delta function potential, which means it also shares the same features with quantum field theories, like being asymptotically free, and in the massless limit, it undergoes dimensional transmutation and it possesses an infrared conformal fixed point.

Balssia antipodarum sp. nov., the first occurrence of the genus Balssia Kemp in the Indo-West Pacific region (Crustacea: Decapoda: Pontoniinae)
Creators: name: BRUCE, Alexander J.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2004

description: A third species of the pontoniine shrimp genus Balssia Kemp, 1922, B. antipodarum sp. nov., is described and
 illustrated. The single specimen was collected from the northern Tasman Sea, near Norfolk Island, at a depth of 111-115 m.
 This is the first occurrence of the genus in the Indo-Pacific region, a maximal range extension as the genus is previously
 known from the Atlantic Ocean and Mediterranean Sea only.

description: The distribution of macroinfauna and Total Organic Carbon (TOC) were investigated in the muddy substrates
 along a transect at 14 m depth in the Grotta Azzurra (Capo Palinuro, Tyrrhenian Sea, Italy), a submarine cave with warm
 (18-24°C) sulphur-water springs in its innermost, aphotic chamber. Due to thermal stratification, sulphidic compounds
 remain trapped above the cooler sea-water in the anoxic upper sulphidic layer supporting dense sulphur-oxidizing bacterial
 mats that detach and disperse when disturbed. The macroinfauna of Grotta Azzurra comprised 97 species. The assemblage
 bore similarities to those previously described from non-cave Mediterranean oligotrophic regions, and also indicated envi-
 ronmental instability. Unlike in other caves, where benthic zonation is prominent, no inward decrease of macroinfaunal
 abundance or diversity was observed. It is assumed that the chemosynthetic inputs in the inner region provide an additio-
 nal source of food that has a positive effect on the colonization and survival of macroinfauna inside the resource limited
 cave environment.

description: Over the past decade, predictive language modeling for code has proven to be a valuable tool for enabling new forms of automation for developers. More recently, we have seen the advent of general purpose "large language models", based on neural transformer architectures, that have been trained on massive datasets of human written text spanning code and natural language. However, despite the demonstrated representational power of such models, interacting with them has historically been constrained to specific task settings, limiting their general applicability. Many of these limitations were recently overcome with the introduction of ChatGPT, a language model created by OpenAI and trained to operate as a conversational agent, enabling it to answer questions and respond to a wide variety of commands from end users. The introduction of models, such as ChatGPT, has already spurred fervent discussion from educators, ranging from fear that students could use these AI tools to circumvent learning, to excitement about the new types of learning opportunities that they might unlock. However, given the nascent nature of these tools, we currently lack fundamental knowledge related to how well they perform in different educational settings, and the potential promise (or danger) that they might pose to traditional forms of instruction. As such, in this paper, we examine how well ChatGPT performs when tasked with answering common questions in a popular software testing curriculum. Our findings indicate that ChatGPT can provide correct or partially correct answers in 55.6% of cases, provide correct or partially correct explanations of answers in 53.0% of cases, and that prompting the tool in a shared question context leads to a marginally higher rate of correct responses. Based on these findings, we discuss the potential promises and perils related to the use of ChatGPT by students and instructors.

Telescoped trajectories from alcohol initiation to disorder in children of alcoholic parents.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The current study tested whether and why COAs show telescoped (adolescent) drinking initiation-to-disorder trajectories as compared to non-COAs. Using longitudinal data from a community-based sample, survival analyses confirmed that COAs progress more quickly from initial adolescent alcohol use to the onset of disorder than do matched controls. Similar risks for telescoping were evident in COAs whose parents were actively symptomatic versus those whose parents were previously diagnosed. Stronger telescoping effects were observed for COAs whose parents showed comorbidity for either depression or antisocial personality disorder. Both greater externalizing symptoms and more frequent, heavier drinking patterns at initiation failed to explain COAs’ risk for telescoping, although externalizing symptoms were a unique predictor of telescoping. This risk for telescoping was also evident for drug disorders. These findings characterize a risky course of drinking in COAs and raise important questions concerning the underlying mechanisms and consequences of telescoping in COAs.

description: Out-of-sample prediction is the acid test of predictive models, yet an independent test dataset is often not available for assessment of the prediction error. For this reason, out-of-sample performance is commonly estimated using data splitting algorithms such as cross-validation or the bootstrap. For quantitative outcomes, the ratio of variance explained to total variance can be summarized by the coefficient of determination or in-sample $R^2$, which is easy to interpret and to compare across different outcome variables. As opposed to the in-sample $R^2$, the out-of-sample $R^2$ has not been well defined and the variability on the out-of-sample $\hat{R}^2$ has been largely ignored. Usually only its point estimate is reported, hampering formal comparison of predictability of different outcome variables. Here we explicitly define the out-of-sample $R^2$ as a comparison of two predictive models, provide an unbiased estimator and exploit recent theoretical advances on uncertainty of data splitting estimates to provide a standard error for the $\hat{R}^2$. The performance of the estimators for the $R^2$ and its standard error are investigated in a simulation study. We demonstrate our new method by constructing confidence intervals and comparing models for prediction of quantitative $\text{Brassica napus}$ and $\text{Zea mays}$ phenotypes based on gene expression data.
SELECTED ASPECTS OF THE RATIONALITY OF USE OF DIURETICS IN AMBULATORY CARE SENIORS IN THE EUROAGEISM H2020 PROJECT (diploma thesis in Czech)

description: Seniors are much more sensitive to adverse drug events and therefore safe pharmacotherapy is one of the main priority in the aging population. Diuretic agents are medications that are often prescribed in older population and may pose a significant risk of adverse drug events, e.g. dehydration, orthostatic hypotensions, falls, ion dysbalances and other serious side effects. The aim of this diploma thesis was to investigate inappropriate prescribing of diuretics in Czech ambulatory care seniors participating in the EUROAGEISM H2020 project, FIP7, and to discuss potential links of such inappropriate prescribing to aspects of ageism.

description: The present study reports the presence of three crab species collected along the Egyptian Mediterranean waters during the period from April, 1989 to January, 2016. They belong to 3 genera of 3 families, under the infra-order Brachyura of the order Decapoda. These species are Notopus dorsipes (Linnaeus, 1758); Ixa monodi Holthuis & Gottlieb, 1956 and Atergatis roseus (Rüppell, 1830). The first one is a new species for the Egyptian Mediterranean waters. The second two species were recently collected from Alexandria coast, Egypt, and the present work backdates their presence in the Egyptian Mediterranean waters from 1989 to 2007, respectively; as well as; it reveals their capture from more different localities in these waters. A short re-description with remarks on the distribution of the recorded species is provided too.
Drop impact on a solid surface: short time self-similarity

Year: 2015
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The early stages of drop impact onto a solid surface are considered. Detailed numerical simulations and detailed asymptotic analysis of the process reveal a self-similar structure both for the velocity field and the pressure field. The latter is shown to exhibit a maximum not near the impact point, but rather at the contact line. The motion of the contact line is furthermore shown to exhibit a 'tank treading' motion. These observations are apprehended at the light of a variant of Wagner theory for liquid impact. This framework offers a simple analogy where the fluid motion within the impacting drop may be viewed as the flow induced by a flat rising expanding disk. The theoretical predictions are found to be in very close agreement both qualitatively and quantitatively with the numerical observations for about three decades in time. Interestingly the inviscid self-similar impact pressure and velocities are shown to depend solely on the self-similar variables $(r/\sqrt{t},z/\sqrt{t})$. The structure of the boundary layer developing along the wet substrate is investigated as well, and is proven to be formally analogous to that of the boundary layer growing in the trail of a shockwave. Interestingly, the boundary layer structure only depends on the impact self-similar variables. This allows to construct a seamless uniform analytical solution encompassing both impact and viscous effects. The depiction of the different dynamical fields enables to quantitatively predict observables of interest, such as the evolution of the integral viscous shearing force and of the net normal force.

Bioaccumulation naturelle du calcium chez Sabella pavonina S. (Annélide Polychète). Étude histochimique, cytochimique et microanalytique
Creators: name: OUAGHI, El Mahjoub
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 1989

description: In Sabella -marine Annelida without calcareous tube- a considerable natural bioaccumulation of calcium was localized in epithelial cells of the nephridia and the digestive tract as well as in the conjonctive matrix and vascular, coelomic and urinary spaces. Two ultrastructural methods of calcium revelation by potassium pyroantimonate and by sodium N, N-Naphthaloylhydroxylamine (NHA) were used. Wave-length dispersive and energy selective X-ray microanalysis indicate that accumulated calcium is associated with phosphorus. The repartition of calcium, located together with pigments within vesicles, shows a progressive evolution. The enrichment in calcium of these pigmentary and calcic vesicles is probably related to the cellular maturation process.

description: We used data from the NICHD Study of Early Child Care and Youth Development and latent class analysis to model patterns of maternal depressive symptoms from infant age 1 month to the transition to adolescence (age 12), and then examined adolescent adjustment at age 15 as a function of the course and severity of maternal symptoms. We identified five latent classes of symptoms in these 1357 women while also taking into account sociodemographic measures: never depressed; stable subclinical; early-decreasing; moderately elevated; chronic. Women with few symptoms were more likely to be married, better educated, and in better physical health than women with more elevated symptoms. Family size and whether the pregnancy was planned also differentiated among classes. At age 15, adolescents whose mothers were in the chronic, elevated, and stable subclinical latent classes reported more internalizing and externalizing problems and acknowledged engaging in more risky behavior than did children of never-depressed mothers. Latent class differences in self-reported loneliness and dysphoria were also found. Finally, several significant interactions between sex and latent class suggested that girls whose mothers reported elevated symptoms of depression over time experienced more internalizing distress and dysphoric mood relative to their male counterparts. Discussion focuses on adolescent adjustment, especially among offspring whose mothers report stable symptoms of depression across their childhoods.

description: The presence of the Lessepsian migrant red-eye round herring Etrumeus golanii (Clupeidae) is confirmed in Tunisian coastal waters with the record of 7 specimens captured in June 2014 in the Gulf of Gabes. Total length of E. golanii individus captured on the Tunisian coast is comprised between 22.5 and 26.5 cm. All specimens are mature females with gonads weighing between 3.97 and 5.25 g. Morphometric and meristic characteristics of the species are described with notes on its parasites. Different developmental stages of 3 parasites Lecithochirium jaffense (Digenea), Anisakis sp. (Nematoda) and Gnathia sp. (Isopoda) were collected. This new record of E. golanii may confirm the rapid range expansion of this Lessepsian migrant in the Central Mediterranean Sea, as well as the infection with parasites newly reported in this host.
New finding of Pholas dactylus (Linnaeus, 1758) (Bivalvia: Pholadidae) on marl rocks from the Central Mediterranean Sea: an insight into this protected species and its rare habitat of high conservation value

description: A new population of the protected species Pholas dactylus was discovered for the first time in the central Mediterranean Sea, more precisely in the southern coast of Sicily. Living populations of P. dactylus have been previously reported, in the Mediterranean Sea, only from the Greek Seas, the Balearic Islands, Turkey, Lebanon and the Italian coast of central Adriatic Sea. The common piddock was observed in five sites characterized by grey-white calcareous marl rocks with a mean density of 1348 ± 672 m-2 and a mean length of 36.8 ± 22.8 mm. A number of other protected species were also found in the same area, including the endolithic bivalve Lithophaga lithophaga, the large bivalve Pinna nobilis, the brown alga Cystoseira amentacea and the Mediterranean seagrass Posidonia oceanica. The last two species form associations that are considered priority habitats according to the Annex I of the SPA/BD Protocol of the Barcelona Convention. Considering the environmental importance of this rare ecosystem, characterized by protected species and habitats, specific conservation strategies should be adopted in the area. Finally, it would be appropriate to introduce the 'facies with P. dactylus' within the 'biocenosis of infralittoral algae' as a priority habitat of the Annex I of the SPA/BD Protocol.

description: Grids of stellar evolution are required in many fields of astronomy/astrophysics, such as planet hosting stars, binaries, clusters, chemically peculiar stars, etc. In this study, a grid of stellar evolution models with updated ingredients and {recently determined solar abundaces} is presented. The solar values for the initial abundances of hydrogen, heavy elements and mixing-length parameter are 0.0172, 0.7024 and 1.98, respectively. The mass step is small enough (0.01 M$_\odot$) that interpolation for a given star mass is not required. The range of stellar mass is 0.74 to 10.00 M$_\odot$. We present results in different forms of tables for easy and general application. The second stellar harmonic, required for analysis of apsidal motion of eclipsing binaries, is also listed. We also construct rotating models to determine effect of rotation on stellar structure and derive fitting formula for luminosity, radius and the second stellar harmonic as a function of rotational parameter. We also compute and list colours and bolometric corrections of models required for transformation between theoretical and observational results. The results are tested for the Sun, the Hyades cluster, the slowly rotating chemically peculiar Am stars and the eclipsing binaries with apsidal motion. The theoretical and observational results along isochrones are in good agreement. The grids are also applicable to rotating stars provided that equatorial velocity is given.

description: The Born-Infeld equation in the plane is usefully captured in complex language. The general exact solution can be written as a combination of holomorphic and anti-holomorphic functions. However, this solution only expresses the potential in an implicit way. We rework the formulation to obtain the complex potential in an explicit way, by means of a perturbative procedure. We take care of the secular behavior common to this kind of approach, by resorting to a symmetry the equation has at the considered order of approximation. We apply the method to build approximated solutions to Born-Infeld electrodynamics. We solve for BI electromagnetic waves traveling in opposite directions. We study the propagation at interfaces, with the aim of searching for effects susceptible to experimental detection. In particular, we show that a reflected wave is produced when a wave is incident on a semi-space containing a magnetostatic field.

description: Self-injurious behaviors are among the leading causes of death worldwide. However, the basic nature of self-injurious thoughts and behaviors (SITBs) is not well-understood because prior studies have relied on long-term, retrospective, aggregate, self-report assessment methods. We used ecological momentary assessment methods to measure suicidal and non-suicidal SITBs as they naturally occur in real-time. Participants were 30 adolescents and young adults with a recent history of self-injury who completed signal- and event-contingent assessments on handheld computers over a 14-day period, resulting in the collection of data on 1262 thought and behavior episodes. Participants reported an average of 5.0 thoughts of nonsuicidal self-injury (NSSI) per week, most often of moderate intensity and short duration (1–30 minutes), and 1.6 episodes of NSSI per week. Suicidal thoughts occurred less frequently (1.1 per week), were of longer duration, and led to self-injurious behavior (i.e., suicide attempts) less often. Details are reported about the contexts in which SITBs most often occur (e.g., what participants were doing, who they were with, and what they were feeling before and after each episode). This study provides a first glimpse of how SITBs are experienced in everyday life and has significant implications for scientific and clinical work on self-injurious behaviors.

description: In low-energy effective string theory, $α'$ corrections involve the coupling of the dilaton field to Gauss-Bonnet term. We assume that the dilaton potential is fine tuned so that the dilaton field may oscillate rapidly for a while around the minimum of its potential but the inflation background is not affected. By numerical method, we find that if the dilaton starts to oscillate at the time of about $\sim 60$ e-folds before the end of inflation, $α^\prime$ correction may bring unusual oscillations to the inflationary gravitational wave spectrum, which might be measurably imprinted in the CMB B-mode polarization.

description: Code verification plays an important role in establishing the credibility of computational simulations by assessing the correctness of the implementation of the underlying numerical methods. In computational electromagnetics, the numerical solution to integral equations incurs multiple interacting sources of numerical error, as well as other challenges, which render traditional code-verification approaches ineffective. In this paper, we provide approaches to separately measure the numerical errors arising from these different error sources for the method-of-moments implementation of the combined-field integral equation. We demonstrate the effectiveness of these approaches for cases with and without coding errors.

description: We study multi-parameter sensing of 2D and 3D vector fields within the Bayesian framework for $SU(2)$ quantum interferometry. We establish a method to determine the optimal quantum sensor, which establishes the fundamental limit on the precision of simultaneously estimating multiple parameters with an $N$-atom sensor. Keeping current experimental platforms in mind, we present sensors that have limited entanglement capabilities, and yet, significantly outperform sensors that operate without entanglement and approach the optimal quantum sensor in terms of performance. Furthermore, we show how these sensors can be implemented on current programmable quantum sensors with variational quantum circuits by minimizing a metrological cost function. The resulting circuits prepare tailored entangled states and perform measurements in an appropriate entangled basis to realize the best possible quantum sensor given the native entangling resources available on a given sensor platform. Notable examples include a 2D and 3D quantum ``compass'' and a 2D sensor that provides a scalable improvement over unentangled sensors. Our results on optimal and variational multi-parameter quantum metrology are useful for advancing precision measurements in fundamental science and ensuring the stability of quantum computers, which can be achieved through the incorporation of optimal quantum sensors in a quantum feedback loop.

description: Among cavitary cells, two types of them, undoubtly primitives ones, are to be found in the seven Vesicularines which have been studied, but even, under very similar features, within a great number of various Gymnolemata Bryozoa (amiboïd vacuolar cells and cells with refractive granulations). Other ones, being more characterized and diversified are cytologically and metabolically specific. The presence of these ones, on the whole, opposes the Vesicularines against next groups, such as Alcyonellinae. Many of these evolved types accumulate glycogenic loads and the extreme frailty of them all leads to artefacts the Authors have tried to define the aspects and genesis of which.

description: Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.

The Newton Committee was set up in 1948 because the investigation procedures had become unsatisfactory and in 1959 the Cairns Committee was established because disquiet was expressed by pilots' organisations and the subject was raised in the House of Commons. These Committees reviewed the law and practice in the 1940s and 1950s. It made comparisons with accident investigation procedure in other modes of transport and examined the systems adopted in other countries. In this thesis a study has been made reviewing the past and present practices of accident investigations during a period of great change in civil air transport. It has been an advantage to see at first hand, in the course of this research, the operation of aircraft accident investigation organisations in the United States and Germany. Certain aspects of the procedures, reviewed 16 years ago and which resulted in the current 1969 Regulations, show a need for revision.

description: Idealized glass transitions are discussed within a novel mode-coupling theory (TMCT) proposed by Tokuyama(Physica A 395,31(2014)). This is done in order to identify common grounds with and differences to the conventional mode-coupling theory (MCT). It is proven that both theories imply the same scaling laws for the transition dynamics, which are characterized by two power-law decay functions and two diverging power-law time scales. However, the values for the corresponding anomalous exponents calculated within both theories differ from each other. It is proven that the TMCT, contrary to the MCT, does not describe transitions with continuously vanishing arrested parts of the correlation functions. It is also demonstrated for a schematic model that the TMCT neither leads to the MCT scenarios for transition-line crossings nor for the appearance of higher-order glass-transition singularities.

description: Tests of interpersonal theories of depression have established that elevated depression levels among peers portend increases in individuals’ own depressive symptoms, a phenomenon known as depression socialization. Susceptibility to this socialization effect may be enhanced during the transition to adolescence as the strength of peer influence rises dramatically. Socialization of depressive symptoms among members of child and adolescent friendship groups was examined over a 1-year period among 648 youth in grades six through eight. Sociometric methods were utilized to identify friendship groups and ascertain the prospective effect of group-level depressive symptoms on youths’ own depressive symptoms. Hierarchical linear modeling results revealed a significant socialization effect and indicated that this effect was most potent for (a) girls and (b) individuals on the periphery of friendship groups. Future studies would benefit from incorporating child and adolescent peer groups as a developmentally salient context for interpersonal models of depression.

description: Meiofauna was collected in a 35 meters deep sublittoral mud, off Banyuls-sur- Mer, by pushing cores in sediment by scuba-diving at two different seasons of the year. The total density is particularly high for a sublittoral mediterranean mud, nematode and harpacticoid copepod numbers ranging from 2,46 106 to 3,52 106m2. Counting other meiofauna taxa, the value reaches 4,48 106 specimens per m2 giving 3,76 g/m2 (dry weight).

description: We further pursue an approach to the sign problem of quantum chromodynamics at nonzero chemical potential, in which configurations of the lattice path integral are gathered into subsets. In the subset construction we multiply each temporal link by center elements independently and in a first step neglect the gauge action. The positivity of the subset weights -- shown for 0+1 dimensions in an earlier study -- extends to larger lattices: for two sites in the temporal direction and arbitrary spatial extent we give a proof of the positivity by decomposing the subset weight in positive summands. From numerical evidence we conjecture that the positivity persists on larger lattices and that the gauge action can be reintroduced through mild reweighting. First results on the quark number obtained with this method in two dimensions are shown as well.

description: Concentrations of organic matter have been evaluated in South Western Brittany coastal seawaters,in april 1970. Dissolved organic carbon and nitrogen, dissolved free fatty acids and particulate organic carbon, have been determined. Concentrations of nitrate and nitrite, obtained when measuring concentrations of organic nitrogen are also reported.
Coastal influence and hydrological conditions explain the relatively high level and noticeable variations of the concentrations of dissolved organic matter. Free fatty acids represent only one or two per cent of dissolved organic matter.

description: An ecological, faunistic and biogeographic study has been made on Pycnogonida of the Canary coasts. Various algal substrates from mediolittoral and infralittoral levels have been studied; moreoever, some data on circalittoral taxa {Dendrophyllia ramea comunity) are included ,down to 300 metres. Among the seaweeds sampled, Corallina mediterranea and Halopteris are the most rich in pycnogonids . This collection contains 366 specimens obtained in 19 stations. Twelve taxa have been identified ; Achelia
echinata, A. langi, A. vulgaris, Ammothella longipes ,Tanystylum conirostre, Ascorhynchus sp. , Anoplodactylus massiliensis, A. angulatus ,Callipallene emaciata, C producta, Endeis spinosa y Rynchotorax monnioti. The first is the more abundant species on the circalittoral level, C. emaciata in the infralittoral , and A. angulatus in the mediolittoral one.
Ascorhynchus sp. is a macaronesian endemic species ; Endeis spinosa, Callipallene emaciata and Tanystylum conirostre are amphiatlantic taxa; Achelia echinata has a large mondial distribution and the others are typical of the Atlantic-Mediterranean region.
Two patterns of colonial water flow in an erect bilaminate bryozoan, the cheilostome Schizotheca serratimargo (Hincks, 1886)

description: The cheilostome bryozoan Schizotheca serratimargo grows in the northern Adriatic Sea pre­ dominantly as adeoniform bushes, less commonly as free, eschariform sheets. Zooids occupied by func­ tioning polypides are commonly confined to the outer 15-20 mm of branch tips. Lophophores placed centrally along branches are equi-tentacled and radially symmetrical ; within the 0.5 mm band along branch margins, lophophores become progressively larger, more inequi-tentacled, laterally elongated, and supported on longer introverts out to the branch edge. These variations in lophophore parameters are related to the colonial pattern of feeding currents, which flow towards the flat branch surfaces, through lophophores, laterally in the space between lophophores and branch surface provided by the extended introverts, and out as a continuous narrow sheet along branch margins. Marginal outflow in the only eschariform sheet seen feeding is supplemented by outflow from chimneys spaced regularly across the frond surface.

description: Many-body interactions give rise to the appearance of exotic phases in Hermitian physics. Despite their importance, many-body effects remain an open problem in non-Hermitian physics due to the complexity of treating many-body interactions. Here, we present a family of exact and numerical phase diagrams for non-Hermitian interacting Kitaev chains. In particular, we establish the exact phase boundaries for the dimerized Kitaev-Hubbard chain with complex-valued Hubbard interactions. Our results reveal that some of the Hermitian phases disappear as non-Hermiticty is enhanced. Based on our analytical findings, we explore the regime of the model that goes beyond the solvable regime, revealing regimes where non-Hermitian topological degeneracy remains. The combination of our exact and numerical phase diagrams provides an extensive description of a family of non-Hermitian interacting models. Our results provide a stepping stone toward characterizing non-Hermitian topology in realistic interacting quantum many-body systems.
