description: Microplastic research is challenging, especially so in a citizen science context, where contamination prevention measures, the small size of particles and tedious microplastic separation and sorting processes complicate the involvement of participants. On this poster we share how we involved school students and their teachers in microplastic research within the citizen science program Plastic Pirates. The Plastic Pirates were inaugurated in 2016 and since then have involved more than 24.000 participants and the program has been extended to other European countries besides Germany. The school students were mainly involved in data and sample collection and preliminary analysis. On this poster, we will give an overview over the Plastic Pirates data quality and management mechanisms used over the last eight years of this program. Based on our experience we recommend for example to focus investigation on the larger fraction of microplastics, to develop data quality mechanisms that do not obstruct the work of the school students in the field and describe how we developed transparent criteria to communicate shortcomings to be able to publish results in peer-reviewed literature.

description: A theoretical study of the structural and electronic properties of the chloride ion and water molecules in the first hydration shell is presented. The calculations are performed on an ensemble of configurations obtained from molecular dynamics simulations of a single chloride ion in bulk water. The simulations utilize the polarizable AMOEBA force field for trajectory generation, and MP2-level calculations are performed to examine the electronic structure properties of the ions and surrounding waters in the external field of more distant waters. The ChelpG method is employed to explore the effective charges and dipoles on the chloride ions and first-shell waters. The Quantum Theory of Atoms in Molecules (QTAIM) is further utilized to examine charge transfer from the anion to surrounding water molecules. From the QTAIM analysis, 0.2 elementary charges are transferred from the ion to the first-shell water molecules. The default AMOEBA model overestimates the average dipole moment magnitude of the ion compared with the estimated quantum mechanical value. The average magnitude of the dipole moment of the water molecules in the first shell treated at the MP2 level, with the more distant waters handled with an AMOEBA effective charge model, is 2.67 D. This value is close to the AMOEBA result for first-shell waters (2.72 D) and is slightly reduced from the bulk AMOEBA value (2.78 D). The magnitude of the dipole moment of the water molecules in the first solvation shell is most strongly affected by the local water-water interactions and hydrogen bonds with the second solvation shell, rather than by interactions with the ion.

description: Ethylene plays an important role in apple fruit development. Its biosynthesis is catalyzed by two enzymes ACS and ACO. The first is considered to catalyzes the rate-limiting step of ethylene production and in apple two different alleles (MdACS1-1 and MdACS1-2) of this gene have been identified. The presence in the promoter region of MdACS1-2 allele of a SINE insertion is considered to be responsible for a low transcription level and a pronounced reduction in ethylene production in apple cultivar homozygous for this allele. However, the specific expression of each MdACS1 allele has never been reported as well as any in vivo analysis of its 5’-flanking region. With the present study we addressed these issues by developing a set of qPCR allele specific primers for MdACS1 and by a functional characterization of the MdACS1 promoters by transient expression analysis. qPCR analysis on different apple tissues and stages of development demonstrated that MdACS1-2 allele is never express and that MdACS1-1 allele is ripening-related and expresses predominantly but not exclusively in apple fruit. To test MdACS1 promoter in fruit the only protocol available in literature for transient transformation of apple fruit was evaluated and optimized. Twenty chimeric promoter::reporter constructs were generated and analyzed by Agrobacterium-transient transformation. The in vivo analysis allowed to identify an enhancer-like region of  261 bp in MdACS1 promoter and a region of 57 bp in MdACS1-2 responsible, also if not alone, in the inactivation of the MdACS1-2 allele. Through the assessment of ethylene production in a segregating progeny derived from the cross between Fuji and Mondial Gala (homozygous for MdACS1-2 allele) we demonstrated that at least two other genes may be involved in apple ethylene production. An hypothesis that could explain the difference between Fuji and Mondial Gala have been proposed.

description: We analyze the spatial variation in the response of the surface geomagnetic field (or the equivalent ionospheric current) to variations in the solar wind. Specifically, we regress a reanalysis of surface external and induced magnetic field (SEIMF) variations onto measurements of the solar wind. The regression is performed in monthly sets, independently for 559 regularly spaced locations covering the entire northern polar region above 50 magnetic latitude. At each location, we find the lag applied to the solar wind data that maximizes the correlation with the SEIMF. The resulting spatial maps of these independent lags and regression coefficients provide a model of the localized SEIMF response to variations in the solar wind, which we call «Spatial Information from Distributed Exogenous Regression.» We find that the lag and regression coefficients vary systematically with ionospheric region, season, and solar wind driver. In the polar cap region the SEIMF is best described by the (B$_{y}$) component of the interplanetary magnetic field (50-75% of total variance explained) at a lag the SEIMF is best described by the solar wind that varies with season and magnetic local time (MLT), from $\sim$15-20 min for dayside and afternoon MLT (except in Oct-Dec) to typically 30-40 min for nightside and morning MLT and even longer (60-65 min) around midnight MLT.

Hidtil har statistikken omfattet registrerede fuldtidsledige, fuldtidsdeltagere i forskellige aktiveringsforanstaltninger samt (passive) kontanthjælpsmodtagere, revalideringsydelse mv. Senere er også personer på efterløn, førtidspension, syge- og barselsdagpenge, samt fleksydelse inkluderet i statistikken.

Fordelen ved statistikken over offentligt forsørgede er, at samtlige individbaserede datakilder bliver behandlet indbyrdes for tidsmæssige overlap. Det betyder, at den enkelte person samlet set højst kan optræde med 37 timer (svarende til en fuldtidsperson, altså en person med en deltagelsesgrad på 100 pct.), når man summerer personens ugentlige timer/deltagelsesgrader i de forskellige ydelsestyper/tilstande (ledighed, aktivering, kontanthjælp, syge/barselsdagpenge, efterløn og førtidspension mv.)
The effectiveness of a structured preoperative teaching program for the adult surgical patient
Creators: name: Ricci, Joanne Roberta
Publisher: name: University of British Columbia
Year: 2010

description: This experimental study was designed to determine the effectiveness of a structured preoperative teaching programme for the adult surgical patient as measured by several indicators. The major questions asked in this study were: What are the effects of a structured preoperative teaching programme upon the adult surgical patient's length of hospital stay, postoperative complications, number of analgesics administered postoperatively, recall of knowledge explained preoperatively, and satisfaction with his preoperative teaching. This study was conducted over a four month period, on one surgical ward of a large general hospital. A total of forty subjects met the criteria of the study, and their informed consent was obtained. The first twenty subjects were assigned to the control group, and received the unstructured, pre-existing preoperative instruction from the staff nurses. The second twenty subjects made up the experimental group and received structured preoperative teaching in small groups conducted by the investigator, with the aid of a slide-taped programme developed specifically for the study. Prior to discharge, each subject was given two questionnaires to complete, and data were collected by means of a patient profile sheet. The two groups of subjects were found to be similar when compared on selected characteristics. The alternative hypotheses of the study were analyzed by means of a t-test, and chi square test at the .05 level of significance. The results revealed no significant effect of the structured preoperative teaching programme upon the adult surgical patient's length of hospital stay, postoperative complications, number of analgesics administered postoperatively, or the degree of satisfaction attained from the preoperative teaching he received. However, statistical significance was found for the patient's ability to recall knowledge explained preoperatively. Implications of this study and recommendations for future research were also suggested.

description: Although fully autonomous mapping methods are becoming more and more common and reliable, still the human operator is regularly employed in many 3D surveying missions. In a number of underwater applications, divers or pilots of remotely operated vehicles (ROVs) are still considered irreplaceable, and tools for real-time visualization of the mapped scene are essential to support and maximize the navigation and surveying efforts. For underwater exploration, image mosaicing has proved to be a valid and effective approach to visualize large mapped areas, often employed in conjunction with autonomous underwater vehicles (AUVs) and ROVs. In this work, we propose the use of a modified image mosaicing algorithm that coupled with image-based real-time navigation and mapping algorithms provides two visual navigation aids. The first is a classic image mosaic, where the recorded and processed images are incrementally added, named 2D sequential image mosaicing (2DSIM). The second one geometrically transform the images so that they are projected as planar point clouds in the 3D space providing an incremental point cloud mosaicing, named 3D sequential image plane projection (3DSIP). In the paper, the implemented procedure is detailed, and experiments in different underwater scenarios presented and discussed. Technical considerations about computational efforts, frame rate capabilities and scalability to different and more compact architectures (i.e. embedded systems) is also provided.

description: The galaxy power spectrum contains information on the growth of structure, the growth rate through redshift space distortions, and the cosmic expansion through baryon acoustic oscillation features. We study the ability of two proposed experiments, BigBOSS and JDEM-PS, to test the cosmological model and general relativity. We quantify the latter result in terms of the gravitational growth index γ, whose value in general relativity is γ\approx 0.55. Significant deviations from this value could indicate new physics beyond the standard model of cosmology. The results show that BigBOSS (JDEM-PS) would be capable of measuring γwith an uncertainty σ(γ) = 0.043 (0.054), which tightens to σ(γ) = 0.031 (0.038) if we include Stage III data priors, marginalizing over neutrino mass, time varying dark energy equation of state, and other parameters. For all dark energy parameters and related figures of merit the two experiments give comparable results. We also carry out some studies of the influence of redshift range, resolution, treatment of nonlinearities, and bias evolution to enable further improvement.

description: In this manuscript, we consider a deformation on the Heisenberg algebra and investigate the effects on the thermodynamics of the Schwarzschild black hole that is surrounded by quintessence matter. To this end, we obtain the temperature, entropy, and heat capacity functions of the black hole by using the standard laws of thermodynamic according to the considered deformation. We show that upper and lower bound values appear on these functions based on the quintessence and deformed algebra. Then, we derive the corrected density of quintessence matter and the black hole's equation of state functions. We compare these results with the standard Schwarzschild black hole with and without quintessence with the graphical methods and interpret the quantum deformation effects.

description: In this paper we elaborate on the symmetric teleparallel gravity (STPG) written in a non-Riemannian spacetime with nonzero nonmetricity, but zero torsion and zero curvature. Firstly we give a prescription for obtaining the nonmetricity from the metric in a peculiar gauge. Then we state that under a novel prescription of parallel transportation of a tangent vector in this non-Riemannian geometry the autoparallel curves coincides with those of the Riemannian spacetimes. Subsequently we represent the symmetric teleparallel theory of gravity by the most general quadratic and parity conserving lagrangian with lagrange multipliers for vanishing torsion and curvature. We show that our lagrangian is equivalent to the Einstein-Hilbert lagrangian for certain values of coupling coefficients. Thus we arrive at calculating the field equations via independent variations. Then we obtain in turn conformal, spherically symmetric static, cosmological and pp-wave solutions exactly. Finally we discuss a minimal coupling of a spin-1/2 field to STPG.

description: Optimization of discrete structures aims at generating a new structure with the better property given an existing one, which is a fundamental problem in machine learning. Different from the continuous optimization, the realistic applications of discrete optimization (e.g., text generation) are very challenging due to the complex and long-range constraints, including both syntax and semantics, in discrete structures. In this work, we present SAGS, a novel Simulated Annealing framework for Graph and Sequence optimization. The key idea is to integrate powerful neural networks into metaheuristics (e.g., simulated annealing, SA) to restrict the search space in discrete optimization. We start by defining a sophisticated objective function, involving the property of interest and pre-defined constraints (e.g., grammar validity). SAGS searches from the discrete space towards this objective by performing a sequence of local edits, where deep generative neural networks propose the editing content and thus can control the quality of editing. We evaluate SAGS on paraphrase generation and molecule generation for sequence optimization and graph optimization, respectively. Extensive results show that our approach achieves state-of-the-art performance compared with existing paraphrase generation methods in terms of both automatic and human evaluations. Further, SAGS also significantly outperforms all the previous methods in molecule generation.

description: The dynamical properties of a model of dark energy in which two scalar fields are coupled by a non-canonical kinetic term are studied. We show that overall the addition of the coupling has only minor effects on the dynamics of the two-field system for both potentials studied, even preserving many of the features of the assisted quintessence scenario. The coupling of the kinetic terms enlarges the regions of stability of the critical points. When the potential is of an additive form, we find the kinetic coupling has an interesting effect on the dynamics of the fields as they approach the inflationary attractor, with the result that the combined equation of state of the scalar fields can approach -1 during the transition from a matter dominated universe to the recent period of acceleration.

The assessment of motor carrier lane profitability : methods and implementation
Creators: name: Cheung, Che Keung
Publisher: name: University of British Columbia
Year: 2010

description: The traffic moved between two cities by a long-haul carrier is commonly termed a lane. The purpose of this study is to demonstrate methods to assess the profitability of individual lanes. To tackle the problem of lane profitability, one needs to have accurate and valid data of revenue and costs. In view of the importance of properly prepared data, a secondary purpose of this study is to recommend accounting procedures to record data in a usable form for further studies of this kind. The concept of revenue for a lane is not difficult to understand. However, the concept of cost for a lane raises some difficult questions. Since a terminal handles traffic from a variety of lanes, the crux of the problem is to disaggregate the terminal costs to each individual lane. Statistical costing is the main tool used in this study. It is not the most accurate method but is less costly than most other methods. Thus, it is often an indeal substitution for detailed engineering studies. Statistical methods have applicability when direct observation of the relationship between cost and output is difficult or impossible. To this end, regression analysis was proposed extensively in the study to examine the behaviour of different cost elements. With a good grasp of the relationship between terminal costs and terminal output (activities) one can apportion the related terminal costs to the lanes of interest. This study presents a normative model. To construct the model, the examination of a common motor carrier's operation has provided much insight regarding (1) the kinds of data that are generally available, (2) how the available data can be improved, and (3) how the constructed model relates to the motor carrier examined. To appreciate the subtleties inherent in this study, a general understanding of the industry as well as the daily operation of a motor carrier is required. To assess the profitability relating to different lanes, one requires some workable methods, and above all, workable data.

description: The redistribution of matter in the deep-sea depends on water-flow currents and turbulent exchange, for which breaking internal waves are an important source. As internal waves and turbulence are essentially three-dimensional 3D, their dynamical development should ideally be studied in a volume of seawater. However, this is seldom done in the ocean where 1D-observations along a single vertical line are already difficult. We present the design, construction and successful deployment of a half-cubic-hectometer (480,000 m3) 3D-T mooring array holding 2925 high-resolution temperature sensors to study weakly density-stratified waters of the 2500-m deep Western Mediterranean. The stand-alone array samples temperature at a rate of 0.5 Hz, with precision <0.5 mK, noise level <0.1 mK and expected endurance of 3 years. The independent sensors are synchronized inductively every 4 h to a single standard clock. The array consists of 45 vertical lines 125 m long, at 9.5 m horizontally from their nearest neighbor. Each line is held under tension of 1.3 kN by a buoyancy element that is released chemically one week after deployment. All fold-up lines are attached to a grid of cables that is tensioned in a 70 m diameter ring of steel tubes. The array is build-up in harbor-waters, with air filling the steel tubes for floatation. The flat-form array is towed to the mooring site under favorable sea-state conditions. By opening valves in the steel tubes, the array is sunk and its free-fall is controlled by a custom-made drag-parachute reducing the average sinking speed to 1.3 m s-1 and providing smooth horizontal landing on the flat seafloor.

description: In 2010, the concept of data lake emerged as an alternative to data warehouses for big data management. Data lakes follow a schema-on-read approach to provide rich and flexible analyses. However, although trendy in both the industry and academia, the concept of data lake is still maturing, and there are still few methodological approaches to data lake design. Thus, we introduce a new approach to design a data lake and propose an extensive metadata system to activate richer features than those usually supported in data lake approaches. We implement our approach in the AUDAL data lake, where we jointly exploit both textual documents and tabular data, in contrast with structured and/or semi-structured data typically processed in data lakes from the literature. Furthermore, we also innovate by leveraging metadata to activate both data retrieval and content analysis, including Text-OLAP and SQL querying. Finally, we show the feasibility of our approach using a real-word use case on the one hand, and a benchmark on the other hand.

description: Motivated by the detection of a recent outburst of the massive luminous blue variable LMC-R71, which reached an absolute magnitude M_V = -9.3 mag, we undertook a systematic study of the optical variability of 1268 massive stars in the Large Magellanic Cloud, using a recent catalog by Bonanos et al. (2009) as the input. The ASAS All Star Catalog (Pojmanski 2002) provided well-sampled light curves of these bright stars spanning 10 years. Combining the two catalogs resulted in 599 matches, on which we performed a variability search. We identified 117 variable stars, 38 of which were not known before, despite their brightness and large amplitude of variation. We found 13 periodic stars that we classify as eclipsing binary (EB) stars, eight of which are newly discovered bright, massive eclipsing binaries composed of OB type stars. The remaining 104 variables are either semi- or non-periodic, the majority (85) being red supergiants. Most (26) of the newly discovered variables in this category are also red supergiants with only three B and four O stars.

description: In this paper, we investigate thermal equilibrium in string gas cosmology which is dominated by closed string.We consider two interesting regimes, Hagedorn and radiation regimes.We find that for short strings in small radius of Hagedorn regime very large amount of energy requested to have thermal equilibrium but for long strings in such system a few energy is sufficient to have thermal equilibrium. On the other hand in the large radius of Hagedorn regime, which pressure is not negligible, we obtain a relation between the energy and pressure in terms of cosmic time which is satisfied by thermal equilibrium. Then we discuss about radiation regime and find that in all cases there is thermal equilibrium.

Connecting spin and statistics in quantum mechanics
Creators: name: Jabs, Arthur
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: Statistical Mechanics (cond-mat.stat-mech)
subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The spin-statistics connection is derived in a simple manner under the postulates that the original and the exchange wave functions are simply added, and that the azimuthal phase angle, which defines the orientation of the spin part of each single-particle spin-component eigenfunction in the plane normal to the spin-quantization axis, is exchanged along with the other parameters. The spin factor (-1)^2s belongs to the exchange wave function when this function is constructed so as to get the spinor ambiguity under control. This is achieved by effecting the exchange of the azimuthal angle by means of rotations and admitting only rotations in one sense. The procedure works in Galilean as well as in Lorentz-invariant quantum mechanics. Relativistic quantum field theory is not required.

Classical and Machine Learning Methods for Event Reconstruction in NeuLAND

subject: FOS: Physical sciences

description: NeuLAND, the New Large Area Neutron Detector, is a key component to investigate the origin of matter in the universe with experimental nuclear physics. It is a core component of the Reactions with Relativistic Radioactive Beams setup at the Facility for Antiproton and Ion Research, Germany. Neutrons emitted from these reactions create a wide range of patterns in NeuLAND. From these patterns, the number of neutrons (multiplicity) and their first interaction points must be reconstructed to determine the neutrons' four-momenta. In this paper, we detail the challenges involved in this reconstruction and present a range of possible solutions. Scikit-Learn classification models and simple Keras-based neural networks were trained on a wide range of input-scaler combinations and compared to classical models. While the improvement in multiplicity reconstruction is limited due to the overlap between features, the machine learning methods achieve a significantly better first interaction point selection, which directly improves the resolution of physical quantities.
Børnefamilieydelser og børnetilskud
Creators: Danmarks Statistik
Publisher: name: Rigsarkivet
Year: 2022

description: Formålet med statistikken om børneydelser er at belyse antal modtagere af børnefamilieydelse og børnetilskud samt beløbene modtaget i ydelse. Modtagere og beløb er opdelt i forskellige grupper (efter arten af ydelse, enlige/samboende familier, antal børn, amter og kommuner.

Børnetilskudsstatistikken trådte i kraft for skatteåret 1957/58, men er udarbejdet i sin nuværende form siden 1987. Statistikken hviler på den til enhver tid gældende lovgivning, og statistikken er offentliggjort i Statistiske Efteretninger
i serien Sociale forhold, sundhed og retsvæsen med titlen Børnefamilieydelse og børnetilskud. 4.kvt.

I Statistiske Efterretninger 1957:86 er omtalt en lovændring (lov nr. 89 af 29. marts 1957) i børnetilskudsordningen. Man forstår, at ordningen minder meget om tidligere års, og at tilskudet er gradueret efter indtægtens størrelse. Der er dog sparsomt med tal i artiklen.

Lov nr. 443 af 6. juli 1973 om børnetilskud og andre familieydelser var grundlag for statistikken i en årrække. Senere blev grundlaget Lov nr. 609 af 29. november 1978 om børnetilskud og andre familieydelser.

1. juli 1987 blev loven ændret til den form, vi kender i dag. Før 1. juli 1987 havde børnetilskudsarterne en anden form end nu og betingelserne for at modtage børnetilskud var lidt anderledes.

Den seneste lovgivning er
1. Børnefamilieydelse: Skatteministeriets bekendtgørelse af lov om en børnefamilieydelse nr. 846 af 4. september 2000 og bekendtgørelse nr. 1029 af 24. oktober 2005 om udbetaling af børnefamilieydelse til personer, der ikke er fuldt skattepligtige efter kildeskattelovens § 1 m.v., og de komunnale revisorers revision af børnefamilieydelse.
2. Børnetilskud: Socialministeriets bekendtgørelse af lov om børnetilskud og forskudsvis udbetaling af børnebidrag lovbekendtgørelse nr. 909 af 3. september 2004.
