description: The Stream Control Transmission Protocol (SCTP) is a Transport Layer protocol that has been proposed as an alternative to the Transmission Control Protocol (TCP) for the Internet of Things (IoT). SCTP, with its four-way handshake mechanism, claims to protect the Server from a Denial-of-Service (DoS) attack by ensuring the legitimacy of the Client, which has been a known issue pertaining to the three-way handshake of TCP. This paper compares the handshakes of TCP and SCTP to discuss its shortcomings and strengths. We present an Uppaal model of the TCP three-way handshake and SCTP four-way handshake and show that SCTP is able to cope with the presence of an Illegitimate Client, while TCP fails. The results confirm that SCTP is better equipped to deal with this type of attack.

description: I review briefly some dynamical models of structures in the outer parts of disc galaxies, including models of polar rings, tidal tails and bridges. I then discuss the density distribution in the outer parts of discs. For this, I compare observations to results of a model in which the disc galaxy is in fact the remnant of a major merger, and find good agreement. This comparison includes radial profiles of the projected surface density and of stellar age, as well as time evolution of the break radius and of the inner and outer disc scale lengths. I also compare the radial projected surface density profiles of dynamically motivated mono-age populations and find that, compared to older populations, younger ones have flatter density profiles in the inner region and steeper in the outer one. The break radius, however, does not vary with stellar age, again in good agreement with observations.

title: Winter distribution of microzooplankton in the Nordic Seas

Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Winter investigations of both phytoplankton and microzooplankton in open oceans are few, hence we know very little about the processes taking place outside the traditional growth seasons. However, winter survival is crucial to all organisms, and to get a better understanding of the winter processes, cruises to the Nordic Seas were organized during two winter seasons (1999 and 2000). The purpose was primarily to study the connection between winter convection and phytoplankton, based on knowledge from a winter study of shelf areas in Northern Norway (Backhaus et al. 1999). From this study we knew that the deep convection was a vital process for initiation of the spring bloom in shallow areas. Now we wanted to investigate the effects on plankton in open oceans where the convective mixing was supposed to transport phytoplankton cells up and down in the water column and keeping them from sinking to the bottom in these deep areas. Additional to the phytoplankton we also collected microzooplankton in our samples, and that gave us an opportunity to include a study of the smallest zooplankton forms in relation to both convective mixing and phytoplankton distribution during winter

description: Das Papier fragt nach der Rolle körperbezogener Vergleichspraktiken im frühneuzeitlichen Kulturkontakt zwischen Indien, dem Osmanischen Reich und dem lateinisch-christlichen Europa, sowie dem Kontakt zwischen jüdischen und christlichen Akteuren innerhalb Europas. Im Besonderen schauen wir dafür Vergleichsformationen und Vergleichsgrammatiken an. Fragt die Vergleichsformation nach den verwandten Sets von tertia, ermöglicht das Konzept der Vergleichsgrammatik, die Verschiebung thematischer Felder (in unserem Fall körperbezogene Vergleichselemente) in der Struktur der Vergleichspraktiken nachzuzeichnen. Mit Hilfe beider heuristischer Konzepte untersuchen wir, wie bei der Ordnung von Menschen körperbezogene Merkmale von den lateinisch-christlichen Autoren (16.–18. Jahrhundert) verwendet wurden. Uns interessiert, wie sich die Vergleichsformationen, die wir als Mesoebene auffassen, ausbildeten und verstetigten. Auf diese Weise macht das Papier Vergleichsformationen und Vergleichsgrammatiken als Konzepte der Mesoebene aus dem SFB 1288 für frühneuzeitliche Situationen des Kulturkontaktes fruchtbar.
description: The paper examines the role of body-related practices of comparing in the early modern cultural contact between India, the Ottoman Empire and Latin-Christian Europe, as well as the contact between Jewish and Christian actors within Europe. In particular, we look at comparative formations (Vergleichsformationen) and comparative grammars (Vergleichsgrammatiken). While the comparative formation asks about the used sets of tertia, the concept of comparative grammar allows us to trace the shifting of thematic fields (in our case, body-related comparative elements) in the structure of comparative practices. With these two heuristic concepts, we examine how Latin-Christian authors (16th–18th century) used body-related features in ordering people. We are interested in how the comparative formations, which we understand as the meso-level, were formed and consolidated. In this way, the paper turns comparative formations and comparative grammars into useful concepts of the meso-level from the SFB 1288 for early modern situations of cultural contact.

Trigonometric protocols for shortcuts to adiabatic transport of cold atoms in anharmonic traps

description: Shortcuts to adiabaticity have been proposed to speed up the "slow" adiabatic transport of an atom or a wave packet of atoms. However, the freedom of the inverse engineering approach with appropriate boundary conditions provides thousands of trap trajectories for different purposes, for example, time and energy minimizations. In this paper, we propose trigonometric protocols for fast and robust atomic transport, taking into account cubic or quartic anharmonicities. The numerical results have illustrated that such trigonometric protocols, particular cosine ansatz, is more robust and the corresponding final energy excitation is smaller, as compared to sine trajectories implemented in previous experiments.

description: Perrona eleonorae group
 This group comprises Perrona eleonorae (Hoernes & Auinger, 1891), Perrona lydiae (Hoernes & Auinger, 1891) and most probably Perrona ? herculea (Mayer-Eymar, 1886). These species seem to be closely related based on their moderately large, solid, buccinoid shells with moderately gradate to conical spire, short siphonal canal and thickened fasciole. Species of the Perrona descendens group are smaller, fusiform rather than buccinoid and usually have shorter spires relative to the last whorl. The shape is unusual for modern Perrona species and especially the weakly tubercular peribasal and perifasciolar cords of P. eleonorae are atypical for Perrona. Nevertheless, P. eleonorae and P. lydiae develop a typical Perrona sculpture on early teleoconch whorls with comma-shaped riblets between two smooth adsutural cords. Therefore, we place this group in Perrona and interpret it as convergent late teleoconch whorl morphology with Granulatocincta nov. gen., which however, differs clearly in its tripartite early teleoconch whorls and the beaded sculpture.

description: This paper considers on a network routing protocol known as Better Approach to Mobile Ad hoc Networks (B.A.T.M.A.N.). The protocol serves two aims: first, to discover all bidirectional links, and second, to identify the best-next-hop for every other node in the network. A key element is that each node will flood the network at regular intervals with so-called originator messages. This paper describes in detail a formalisation of the B.A.T.M.A.N. protocol. This exercise revealed several ambiguities and inconsistencies in the RFC. We developed two models. The first implements, if possible, a literal reading of the RFC, while the second model tries to be closer to the underlying concepts. The alternative model is in some places less restrictive, and rebroadcasts more often when it helps route discovery, and will on the other hand drop more messages that might interfere with the process. We verify for a basic untimed model that both interpretations ensure loop-freedom, bidirectional link discovery, and route-discovery. We use simulation of a timed model to compare the performance and found that both models are comparable when it comes to the time and number of messages needed for discovering routes. However, the alternative model identifies a significantly lower number of suboptimal routes, and thus improves on the literal interpretation of the RFC.

description: No abstracts are to be cited without prior reference to the author.Whales and fish use a wide range of hunting tactics in order to catch their prey. Predator-prey interactions have been seen during the massive wintering of herring (Clupea harengus) in steep bottomed topography in Lofoten, northwestern Norway. We applied hydro-acoustics to document how killer whales (Orcinus orca) and Atlantic saithe (Pollachius virens) herd and trap herring in shallow waters before attacking their prey. A group of eight killer whales and a shoal consisting of hundreds of saithe concentrated their attack on the side of the herring schools that faced away from the shallow area. They thus effectively herded the herring towards the shallower water. The predators then surrounded the schools, preventing the herring from escaping to deeper, darker and safer water. Some predators attacked herring by penetrating the school, while others continued surrounding the school. These are the first, well-documented hydro-acoustic observations of this hunting tactic. Further research will reveal if this hunting tactic is common and widespread among other species of marine mammals and fish preying on fish schools in coastal waters.

description: The hardware/software boundary in modern heterogeneous multicore computers is increasingly complex, and diverse across different platforms. A single memory access by a core or DMA engine traverses multiple hardware translation and caching steps, and the destination memory cell or register often appears at different physical addresses for different cores. Interrupts pass through a complex topology of interrupt controllers and remappers before delivery to one or more cores, each with specific constraints on their configurations. System software must not only correctly understand the specific hardware at hand, but also configure it appropriately at runtime. We propose a formal model of address spaces and resources in a system that allows us to express and verify invariants of the system's runtime configuration, and illustrate (and motivate) it with several real platforms we have encountered in the process of OS implementation.

description: The partitioning of a system model will condition the structure of the controller as well as its design. In order to partition a system model, one has to know what states and inputs to group together to define subsystem models. For a given partitioning, the total magnitude of the interactions between subsystem models is evaluated. Therefore, the partitioning problem seeking for weak interactions can be posed as a minimization problem. Initially, the problem is formulated as a non-linear integer minimization that is then relaxed into a linear integer programming problem. It is shown within this paper that cuts can be applied to the initial search space in order to find the least interacting partitioning; only composed of controllable subsystems. Two examples are given to demonstrate the methodology.

description: This paper sheds new light on the stability properties of solitary wave solutions associated with models of Korteweg-de Vries and Benjamin\&Bona\&Mahoney type, when the dispersion is very lower. Via an approach of compactness, analyticity and asymptotic perturbation theory, we establish sufficient conditions for the existence of exponentially growing solutions to the linearized problem and so a criterium of linear instability of solitary waves is obtained for both models. Moreover, the nonlinear stability and linear instability of the ground states solutions for both models is obtained for some specific regimen of parameters. Via a Lyapunov strategy and a variational analysis we obtain the stability of the blow-up of solitary waves for the critical fractional KdV equation. The arguments presented in this investigation has prospects for the study of the instability of traveling waves solutions of other nonlinear evolution equations.

description: Principal component analysis (PCA) is used on datasets with vast numbers of numeric variables and limited observations (e.g., dairy herd improvement [DHI] data) for unbiased selection of uncorrelated variables that describe the largest amount of variance. Cluster analysis (CA) divides objects of interest (e.g., dairy herds) into groups on the basis of similarity in multiple characteristics simultaneously. The aims of this project were to develop a novel method for discovering important DHI variables by use of PCA and then grouping herds by those variables via CA, and to survey herds to determine herd management characteristics of each group.

description: No abstracts are to be cited without prior reference to the author.Individual horizontal movements of a marine predator such as cod can be monitored by electronic data storage tags, if the archived data relate to horizontal locations. We propose here a geo-location method for the Baltic Sea. Distinct vertical and horizontal gradients exist in temperature and salinity, and temperature-salinity combinations at depth are unique for a given location. Individually based measurements of pressure, temperature and salinity at a given point of time can hence be related to a unique location, if highly resolved spatial fields of temperature and salinity are available. The focus of this paper was to investigate the level of uncertainty in location estimates due to sensor errors. Estimates of the physical parameter fields were based on a hydrodynamic model and assumed unbiased. We tested sensor dynamics and accuracy of two electronic data storage tags in situ. Both tags had sensors for pressure, conductivity and temperature. The confidence limits of the tag measurements were transformed to confidence limits of horizontal location in a given depth.

description: We consider the cosmological implications of a gravitational theory containing two vector fields coupled minimally to gravity as well as a generalized Chern-Simons term that couples the two vector fields. One of the vector fields is the usual Maxwell field, while the other is a constrained vector field with constant norm included in the action via a Lagrange multiplier. The theory admits a de Sitter type solution, with healthy cosmological perturbations. We will show that there is 6 degrees of freedom propagate on top of de Sitter space-time, two tensor polarizations and four degrees of freedom related to two massless vector fields interacting with each other via Chern-Simons interaction term. We also investigate in detail the behavior of the geometric and physical parameters of a homogeneous and anisotropic Bianchi type I Universe, by using both analytical and numerical methods, by assuming that the matter content of the Universe can be described by the stiff causal and pressureless dust fluid equations of state. The time evolution of the Bianchi type I Universe strongly depends on the initial conditions of the physical and geometrical quantities, as well as on the numerical values of the model parameters. Two important observational parameters, the mean anisotropy parameter, and the deceleration parameter, are also studied in detail, and we show that independently of the matter equation of state the cosmological evolution of the Bianchi type I Universe always ends in an isotropic and exponentially accelerating, de Sitter type, phase.

description: We study glide protected topological (GSPT) phases of interacting bosons and fermions in three spatial dimensions certain on-site symmetries. They are crystalline SPT phases, which are distinguished from a trivial product state only in the presence of non-symmorphic glide symmetry. We classify these GSPT phases with various on-site symmetries such as $U(1)$ and time reversal, and show that they can all be understood by stacking and coupling two-dimensional short-range-entangled phases in a glide-invariant way. Using such a coupled layer construction we study the anomalous surface topological orders of these GSPT phases, which gap out the two-dimensional surface states without breaking any symmetries. This framework is demonstrated in many examples, including the non-symmorphic topological insulator with "hourglass fermion" surface states.

description: Calving-related losses, such as stillbirth, affect the bottom line of dairy operations, and the underlying causes should be investigated to develop preventive procedures that consider both animal welfare and profitability. Comprehensive training on calving management practices for dairy personnel is a top priority, especially to reduce the prevalence of stillbirth in dairy herds. Risk factors affecting stillbirth vary from farm to farm, and blanket recommendations often fail when applied to a variety of different herds. Therefore, the objective of this study was to assess the effect of time of birth during the 1-hour period before and after the work shift transition of calving personnel (n=3) on 1 commercial dairy on the prevalence of stillbirth in Holstein cows.

description: Correct and efficient initialization of wireless sensor networks can be challenging in the face of many uncertainties present in ad hoc wireless networks. In this paper we examine an implementation for the formation of a cluster-tree topology in a network which operates on top of the TSCH MAC operation mode of the IEEE 802.15.4 standard, and investigate it using formal methods. We show how both the mCRL2 language and toolset help us in identifying scenarios where the implementation does not form a proper topology. More importantly, our analysis leads to the conclusion that the cluster-tree formation algorithm has a super linear time complexity. So, it does not scale to large networks.

description: A major cause of reduced performance and death in neonatal dairy calves is diarrhea, regardless of cause. Cryptosporidium parvum is a protozoal pathogen that is frequently associated with diarrhea in neonatal dairy calves. Virtually all dairy calves that are raised on commercial operations are infected with C. parvum by 3 weeks of age. Conventional colostrum does not contain protective levels of antibodies against C. parvum, and therapeutic agents with efficacy for prevention of C. parvum oocyst excretion or reduction of clinical severity of diarrhea are lacking. The objective of this study was to determine the efficacy of an inactivated C. parvum preparation as an oral immunogen in a colostrum-deprived calf challenge model.

The data was obtained from the summer acoustic surveys between 1998 and 2002 along the Peruvian coast and also landings data of anchovy and ARGOS system were used. The oceanographic parameters used in the analysis were sea surface temperature (SST), sea surface salinity, dissolved oxygen from the same surveys and additionally for the analysis was used the distance to the coast. Results indicated the abundance and distribution and behaviour of the anchovy during the summer corresponds to particular conditions present between the cruises because the Humboldt marine ecosystem is subject to frequent variability. During the summer the abundance of the anchovy is concentrated near to the coast associated with Cold Coastal Water and Mixed Water and possibly the plankton is an important regulating. In autumn and spring the anchovy is distributed more than 100nm offshore and more than 150nm offshore in cold event as La Niña

description: Differences in natural light conditions caused by changes in moonlight are known to affect perceived predation risk in many nocturnal prey species. As artificial light at night (ALAN) is steadily increasing in space and intensity, it has the potential to change movement and foraging behavior of many species as it might increase perceived predation risk and mask natural light cycles. We investigated if partial nighttime illumination leads to changes in foraging behavior during the night and the subsequent day in a small mammal and whether these changes are related to animal personalities. We subjected bank voles to partial nighttime illumination in a foraging landscape under laboratory conditions and in large grassland enclosures under near natural conditions. We measured giving-up density of food in illuminated and dark artificial seed patches and video recorded the movement of animals. While animals reduced number of visits to illuminated seed patches at night, they increased visits to these patches at the following day compared to dark seed patches. Overall, bold individuals had lower giving-up densities than shy individuals but this difference increased at day in formerly illuminated seed patches. Small mammals thus showed carry-over effects on daytime foraging behavior due to ALAN, i.e., nocturnal illumination has the potential to affect intra- and interspecific interactions during both night and day with possible changes in personality structure within populations and altered predator-prey dynamics.

description: Natural phenomena frequently involve a very large number of interacting molecules moving in confined regions of space. Cellular transport by motor proteins is an example of such collective behavior. We derive a deterministic compartmental model for the unidirectional flow of particles along a one-dimensional lattice of sites with nearest-neighbor interactions between the particles. The flow between consecutive sites is governed by a soft simple exclusion principle and by attracting or repelling forces between neighboring particles. Using tools from contraction theory, we prove that the model admits a unique steady-state and that every trajectory converges to this steady-state. Analysis and simulations of the effect of the attracting and repelling forces on this steady-state highlight the crucial role that these forces may play in increasing the steady-state flow, and reveal that this increase stems from the alleviation of traffic jams along the lattice. Our theoretical analysis clarifies microscopic aspects of complex multi-particle dynamic processes.

description: Background Coronavirus disease (COVID-19) has a severe impact on all aspects of patient care. Among the numerous biomarkers of potential validity for diagnostic and clinical management of COVID-19 are biomarkers at the interface of iron metabolism and inflammation. Methods The follow-up study included 54 hospitalized patients with laboratory-confirmed COVID-19 with a moderate and severe/critical form of the disease. Iron deficiency specific biomarkers such as iron, ferritin, transferrin receptor, hepcidin, and zinc protoporphyrin (ZnPP) as well as relevant markers of inflammation were evaluated twice: in the first five days when the patient was admitted to the hospital and during five to 15 days; and their validity to diagnose iron deficiency was further assessed. The regression and Receiver Operating Characteristics (ROC) analyses were performed to evaluate the prognosis and determine the probability for predicting the severity of the disease in the first five days of COVID-19. Results Based on hemoglobin values, anemia was observed in 21 of 54 patients. Of all iron deficiency anemia-related markers, only ZnPP was significantly elevated (P<0.001) in the anemic group. When patients were grouped according to the severity of disease, slight differences in hemoglobin or other anemia-related parameters could be observed. However, the levels of ZnPP were significantly increased in the severely ill group of patients. The ratio of ZnPP to lymphocyte count (ZnPP/L) had a discrimination power stronger than the neutrophil to lymphocyte count ratio (N/L) to determine disease severity. Additionally, only two markers were independently associated with the severity of COVID-19 in logistic regression analysis; D-dimer (OR (5.606)(95% CI 1.019–30.867)) and ZnPP/L ratio (OR (74.313) (95% CI 1.081–5108.103)). Conclusions For the first time ZnPP in COVID-19 patients were reported in this study. Among all iron-related markers tested, ZnPP was the only one that was associated with anemia as based on hemoglobin. The increase in ZnPP might indicate that the underlying cause of anemia in COVID-19 patients is not only due to the inflammation but also of nutritional origin. Additionally, the ZnPP/L ratio might be a valid prognostic marker for the severity of COVID-19.

description: Lower concentrations of coliform bacteria in maternal colostrum (MC) have been associated with enhanced IgG absorption in calves. Mannan-oligosaccharide, a gut active carbohydrate (GAC) derived from yeast cell walls, can adsorb pathogens expressing type-1-fimbriae, which reduces their ability to colonize the gastrointestinal tract. Results of preliminary research suggest that feeding GAC in colostrum enhanced serum IgG concentration in calves. The purpose of this study was to investigate whether addition of a GAC (Bio-MOS®. Alltech, Inc.) to colostrum would increase IgG absorption in newborn calves.

description: Interoception is an often neglected but crucial aspect of the human minimal self. In this perspective, we extend the embodiment account of interoceptive inference to explain the development of the minimal self in humans. To do so, we first provide a comparative overview of the central accounts addressing the link between interoception and the minimal self. Grounding our arguments on the embodiment framework, we propose a bidirectional relationship between motor and interoceptive states, which jointly contribute to the development of the minimal self. We present empirical findings on interoception in development and discuss the role of interoception in the development of the minimal self. Moreover, we make theoretical predictions that can be tested in future experiments. Our goal is to provide a comprehensive view on the mechanisms underlying the minimal self by explaining the role of interoception in the development of the minimal self.

description: No abstracts are to be cited without prior reference to the author.Eggs of sardine and anchovy are located at subsurface and can be sampled using the CUFES pump (continuous underway fish egg sampler). Operating the CUFES pump during fisheries acoustic surveys allows for the joint mapping of the spawning fish and their eggs. This has the potential to allow for the direct estimation of in situ daily fecundity and consequently the estimation the fish stock by two methods (echointegration and daily egg production) using one vessel only. The present work is a first attempt to do so and analyses the coherence in the results of the echo-integration and CUFES derived egg production. A simple model for the vertical distribution of eggs was used to estimate egg abundance given the CUFES subsurface egg density records and the eddy diffusivity coefficients derived from a 3D hydrodynamic model. Egg stages were aged using average temperature along the modelled vertical egg distribution and a mortality curve between egg abundance at difference ages was used to estimate in situ daily egg production. The adult fish abundance was estimated using the acoustic records and the mid-water identification trawl hauls. The spawning fraction, sex ratio and gonado somatic index were assumed and taken to be average published values at peak spawning. By dividing the egg production by the spawning fish abundance, in situ daily fecundity was estimated (number of eggs per somatic gram of spawning female) and compared to the batch daily fecundity derived from published laboratory gonad histology results. The analysis was undertaken using IFREMER’s fisheries acoustic survey in may 2000 which covered the French shelf of Biscay. During that survey the CUFES was operated in collaboration with AZTI and coupled with the acoustics. Estimated in situ daily fecundity was 6% of that estimated by gonad histology for anchovy and 56%for sardine, meaning that the two sampling methods for the eggs (CUFES) and the fish (acoustics) were not in coherence requiring further investigation of the eggs vertical distributions, their modelling and sampling. There was one spawning ground for sardine on which estimates agreed and this served to interpret the reasons of discrepancy in the other areas.

description: Many studies have recently documented the orbital response of eccentric binaries accreting from thin circumbinary disks, characterizing the change in binary semi-major axis and eccentricity. We extend these calculations to include the precession of the binary's longitude of periapse induced by the circumbinary disk, and we characterize this precession continuously with binary eccentricity $e_b$ for equal mass components. This disk-induced apsidal precession is prograde with a weak dependence on binary eccentricity when $e_b \lesssim 0.4$ and decreases approximately linearly for $e_b \gtrsim 0.4$; yet at all $e_b$ binary precession is faster than the rates of change to the semi-major axis and eccentricity by an order of magnitude. We estimate that such precession effects are likely most important for sub-parsec separated binaries with masses $\lesssim 10^7 M_\odot$, like LISA precursors. We find that accreting, equal-mass LISA binaries with $M < 10^6 M_\odot$ (and the most massive $M \sim 10^7 M_\odot$ binaries out to $z \sim 3$) may acquire a detectable phase offset due to the disk-induced precession. Moreover, disk-induced precession can compete with General Relativistic precession in vacuum, making it important for observer-dependent electromagnetic searches for accreting massive binaries -- like Doppler boost and binary self-lensing models -- after potentially only a few orbital periods.
