description: The integration of wireless communication and radar sensing is gaining the interest of researchers from wireless communication and radar societies. Sensing in Integrated Communication and Sensing (ICAS) systems differs from the traditional radar system in the configuration of transmitter-target-receiver, the operating frequency bands, and the transmitting waveform. It is necessary to understand how target electromagnetic signatures behave in this context. Therefore, this paper presents measurements and analysis of two important target signatures, reflectivity and micro-Doppler, for sensing in ICAS. These target signatures are measured in the state-of-the-art measurement system, Bistatische-Radar-Messeinrichtung (BiRa).

Evidence for a deficit of young and old stars in the Milky Way inner in-plane disc

description: We give independent proof of the deficit of stars in the in-plane central disc with respect to the predictions of a pure exponential density distribution. We use three different methods: 1) the inversion of the red clump giant distribution in near-infrared colour-magnitude diagrams to obtain the star density along the line of sight; 2) the determination of the density distribution of 1612 MHz sources by means of the distance determination of OH/IR sources from their kinematical information; 3) an analysis of near and mid-infrared star counts and comparison with models. All the tests give the same result: a defect of stars in the inner disc with respect to an exponential disc (either with constant scaleheight or extrapolated from the outer disc), but only in near plane regions. This deficit might be interpreted as a flare in the vertical distribution. The in-plane density is almost independent of R and not an exponential law. Further away from the plane, however, the density increases towards the centre due to the increase of the scaleheight. Tests also show that this result cannot be due to extinction. The deficit affects both the young and the old populations, so it is probably a rather stable feature of the disc, and might be due to the existence of an in-plane bar sweeping the near-plane stars.

description: We develop a general equality-constrained nonlinear optimization algorithm based on a smooth penalty function proposed by Fletcher (1970). Although it was historically considered to be computationally prohibitive in practice, we demonstrate that the computational kernels required are no more expensive than other widely accepted methods for nonlinear optimization. The main kernel required to evaluate the penalty function and its derivatives is solving a structured linear system. We show how to solve this system efficiently by storing a single factorization each iteration when the matrices are available explicitly. We further show how to adapt the penalty function to the class of factorization-free algorithms by solving the linear system iteratively. The penalty function therefore has promise when the linear system can be solved efficiently, e.g., for PDE-constrained optimization problems where efficient preconditioners exist. We discuss extensions including handling simple constraints explicitly, regularizing the penalty function, and inexact evaluation of the penalty function and its gradients. We demonstrate the merits of the approach and its various features on some nonlinear programs from a standard test set, and some PDE-constrained optimization problems.

Fog Machine : The Video Game as a Medium for Architectural Imagining
Creators: name: Itani, Ayman
Publisher: name: The University of British Columbia
Year: 2022

description: Responding to the growing role of virtual space in our lives, as well as the increasing use of video game technologies for architectural visualization, this graduate project examines how video game spaces can influence materiality and interactivity in architecture. The project first explores a breadth of research on the unique qualities of video games that make them a valuable opportunity for architectural representation and generation. The ability to change rulesets of reality, for instance, allows for new forms of spatial expression in game space. Interactivity is also integral to games, leading to spatial representations that provide users with agency, embed events into the architecture, and become realized places. To demonstrate the potential of the video game as a medium for architectural imagining, this project involves the author’s creation of a video game named Fog Machine: a building simulator and platformer that allows players to build architecture out of fog. By featuring fog, the project aims to explore how, in virtual space, the immaterial can become material. Furthermore, the immaterial can become responsive, dialoguing with the player during their creation of space. Different types of fog have different attributes, providing the player with a variety of ways they can express themselves through the fog structures they create. Fog Machine illustrates how video games can extend architecture’s visual language, establish a fluid discourse between user and space, and formulate architecture with an ethos of play.

description: We consider an abstract mixed variational problem governed by a nonlinear operator $A$ and a bifunctional $J$, in a real reflexive Banach space $X$. The operator $A$ is assumed to be continuous, Lipschitz continuous on each bounded subset of $X,$ and generalized monotone. First, we pay attention to the unique solvability of the problem. Next, we prove a continuous dependence result of the solution with respect to the data. Based on this result we prove the existence of at least one solution for an associated optimization problem. Finally, we apply our abstract results to the well-posedness and the optimization of an antiplane frictional contact model for nonlinearly elastic materials of Hencky-type.

Exploiting Orbital Constraints from Optical Data to Detect Binary Gamma-ray Pulsars

description: It is difficult to discover pulsars via their gamma-ray emission because current instruments typically detect fewer than one photon per million rotations. This creates a significant computing challenge for isolated pulsars, where the typical parameter search space spans wide ranges in four dimensions. It is even more demanding when the pulsar is in a binary system, where the orbital motion introduces several additional unknown parameters. Building on earlier work by Pletsch & Clark (arXiv:1408.6962), we present optimal methods for such searches. These can also incorporate external constraints on the parameter space to be searched, for example, from optical observations of a presumed binary companion. The solution has two parts. The first is the construction of optimal search grids in parameter space via a parameter-space metric, for initial semicoherent searches and subsequent fully coherent follow-ups. The second is a method to demodulate and detect the periodic pulsations. These methods have different sensitivity properties than traditional radio searches for binary pulsars and might unveil new populations of pulsars.

Data coding and harmonization: How DataCoH and Charmstats are transforming social science data

Publisher: name: Zenodo
Year: 2012

description: Comparative social researchers are often confronted with the challenge of making key theoretical concepts comparable across nations and/or time. One example is the socio-demographic variable 'Education'. To operationalize 'education' researchers must review multiple educational systems across nations and/or changing educational structures within one nation across time. Further, researchers have multiple ways to recode education into a harmonized variable including (inter alia): the Hoffmeyer-Zlotnik/Warner matrix; the CASMIN education scheme; the International Standard Classification of Education; or a harmonized variable provided by the dataset itself. GESIS is developing two electronic resources to assist social researchers. The website DataCoH (Data Coding and Harmonization) will provide a centralized online library of data coding and harmonization for existing variables to increase transparency and variable replication. DataCoH initially will contain socio-demographic variables used across the social sciences and then expand to discipline-specific variables. The software program Charmstats (Coding and Harmonizing Statistics) will provide a structured approach to data harmonization by allowing researchers to: 1) download harmonization protocols; 2) document variable coding and harmonization processes; 3) access variables from existing datasets for harmonization; and 4) create harmonization protocols for publication and citation. This paper explains DataCoH and Charmstats and demonstrates how they work.

description: Epithele aff. citrispora Boidin, Lanq. & Gilles
Basidiome resupinate, effused, hymenial surface smooth with numerous sterile hyphal pegs, white to cream. Hyphal pegs composed of skeletal hyphae with many crystals. Generative hyphae with clamps, thin-walled, 2–3 µm in diam., skeletal hyphae thick-walled, about 2–4 µm in diam. Hyphidia and dendrohyphidia present in hymenium. Cystidia absent. Basidia short cylindrical, 25–30 × 8–10 µm, with four sterigmata, and a basal clamp. Basidiospores citriform, biapiculate, distal apiculus refractive in KOH, smooth, thin-walled, (11–)14–19 × 5.5–7 µm, IKI–, CB– (Fig. 5).
 The species agrees with E. citrispora in distinguishing characters of the species as the presence of skeletal hyphae in the hyphal pegs and context, dendrohyphidia, and in the citriform, acyanophilous basidiospores. The Amazonian specimen has slightly narrower basidiospores than described in the original description (7–9 µm wide) of E. citrispora from the Ivory Coast and Gabon (Boidin & Lanquetin 1983). Epithele interrupta Bres. and E. nikau G. Cunn. are morphologically closely related species but differ in having fusiform, nonbiapiculate basidiospores (Boidin & Gilles 2000).

description: Clinical decision support systems combine knowledge and data from a variety of sources, represented by quantitative models based on stochastic methods, or qualitative based rather on expert heuristics and deductive reasoning. At the same time, case-based reasoning (CBR) memorizes and returns the experience of solving similar problems. The cooperation of heterogeneous clinical knowledge bases (knowledge objects, semantic distances, evaluation functions, logical rules, databases...) is based on medical ontologies. A multi-agent decision support system (MADSS) enables the integration and cooperation of agents specialized in different fields of knowledge (semiology, pharmacology, clinical cases, etc.). Each specialist agent operates a knowledge base defining the conduct to be maintained in conformity with the state of the art associated with an ontological basis that expresses the semantic relationships between the terms of the domain in question. Our approach is based on the specialization of agents adapted to the knowledge models used during the clinical steps and ontologies. This modular approach is suitable for the realization of MADSS in many areas.

description: Avulsions remain a critical but understudied aspect of debris-flow fans and flow hazard. A substantial body of work on fluvial systems provides a conceptual framework for understanding avulsions, but equivalent research on debris-flow systems has lagged behind. A small but growing set of field examples and analogue experiments shows that many, but not all, avulsions on debris- flow fans follow a relatively predictable ‘avulsion cycle’ that consists of (1) deposition of debris-flow material in the active channel, (2) backstepping of deposition toward the fan apex in one or more small- to medium-sized surges or flows, and (3) avulsion during a subsequent larger surge or flow that leaves the channel and establishes a new pathway down the fan. Debris flows tend to occupy persistent pathways on the time scale of individual flows, but over longer time scales (perhaps greater than ~5-20 flows, based on very limited data) flows tend to avulse to fill topographic lows, leading to compensational behavior. Avulsions may be encouraged by sequences of small- to medium-sized flows followed by a large flow, and discouraged by sequences of large flows in succession, although this idea remains speculative and needs to be tested. Avulsion frequency is important for understanding flow hazard but is poorly constrained, and cannot yet be predicted as a function of either flow or catchment characteristics. The advent of new, high-resolution topographic data from fan surfaces, coupled with methods to estimate the timing and abandonment of deposition on a wide range of fans, should allow us to begin to make some initial estimates of avulsion frequency and to understand the key controls on the timing and pattern of avulsions.

The Mephistro is under construction. ASMS has been running on robotic mode since 2017. The core instruments: Cloud Sensor, All-Sky Camera and Autonomous-DIMM that are developed by our group, together with the commercial Meteorological Station and Sky Quality Meter, are combined into the astronomical optical site monitoring system. The new Cloud Sensor's Cloud-Clear Relationship is presented for the first time, which is used to calculate the All-Sky cloud cover. We designed the Autonomous-DIMM located on a tower, with the same height as LJT. The seeing data have been observed for a full year. ASMS's data for the year 2019 are also analysed in detail, which are valuable to observers.

Research on Cognitive Aspects of Classification: Effects on Metadata Practice and Standards

Publisher: name: Zenodo

description: Metadata practitioners and standards developers typically take classifications as given. Rarely do they look at how these were created and whether they make sense for respondents or data users. This talk will break tradition and discuss this issue. We considered a question in the Current Population Survey in the US on self-employment, called Class of Worker (COW). The COW question reads: "Were you employed by government, a private company, a non-profit organization, or were you self-employed (or working in the family business)?" The basic question was whether these four response options make sense together. Said another way, does the COW classification make sense for data users? Based on research done by the Small Business Administration and independent researchers, we suspected the answer was No. To investigate this, we paid 90 volunteers to come to BLS and classify a set of twelve job description vignettes based on two different groupings of the COW classification. The data show answering COW is a difficult task. Using research from cognitive psychology, we are now able to provide reasons for this, and we propose new roles for metadata practitioners and new considerations for metadata standards developers.

description: The main economic goal of copper consumer is to maximize certain benefits, while the goal of copper manufacturers is maximizing the profit. From an economic point of view, the optimum level between these two goals, is the one where the difference between the cost and economic impact is greatest. However, the economic optimum level may not be the best from the environmental point of view. The focus of the paper is on the production and consumption of copper in the world, as well as the performance of the price of copper on LME (London Metal Exchange). Bearing in mind that the production of copper resulting external costs that are not included in the price of copper, the aim of the paper refers to point out the significance of introducing external cost in the model of supply and demand of copper in the stock market.
Do Red Galaxies Form More Stars Than Blue Galaxies?
Creators: name: Steinhardt, Charles L.
Publisher: name: arXiv
Year: 2024
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: A new model is proposed in which typical galaxies form most of their stellar mass in a phase with an intrinsically red stellar population. In the standard picture, galaxies with intrinsically red stellar populations are believed to have old stellar populations, so that only galaxies with blue stellar populations have significant star formation, and subsequent changes to the stellar population come from predominantly from aging and merging populations which have already formed. However, several observational puzzles have developed which are difficult to reconcile with this standard scenario. The most massive blue star-forming galaxies, presumed to be at the end of their stellar mass growth, are $\sim 1$ dex less massive, have a $\sim 1$ dex lower $M_*/M_{BH}$ ratio, and have a bottom-lighter IMF than local quiescent galaxies. Here, a new solution is proposed: at low temperature and high metallicity, galaxies can continue to form stars efficiently without being able to form O and B stars. These red star-forming galaxies would have many of the same properties of the population currently described as post-starburst galaxies, allowing a new interpretation of their origin. Finally, additional falsifiable observational predictions of this model are also discussed.

Whereas atoms in trimers are found in fcc sites only, monomers as well as atoms in dimers can occupy the stable fcc as well as the metastable hcp site. In fact the dimer fcc-hcp configuration was found to be only 1.3 meV less favorable with respect to the fcc-fcc configuration. This enables a confined intra-cell dimer motion, which at temperatures below 5 K is dominated by thermally assisted tunneling.

description: We discuss in detail the relation between the gauge fixed and gauge invariant BRST cohomology. We showed previously that in certain gauges some cohomology classes of the gauge-fixed BRST differential do not correspond to gauge invariant observables. We now show that in addition ``accidental'' conserved currents may appear. These correspond one-to-one to observables that become trivial in this gauge. We explicitly show how the gauge-fixed BRST cohomology appears in the context of the Quantum Noether Method.

description: We consider charge transport through a nanoscopic object, e.g. single molecules, short nanotubes, or quantum dots, that is weakly coupled to metallic electrodes. We account for several levels of the molecule/quantum dot with level-dependent coupling strengths, and allow for relaxation of the excited states. The current-voltage characteristics as well as the current noise are calculated within first-order perturbation expansion in the coupling strengths. For the case of asymmetric coupling to the leads we predict negative-differential-conductance accompanied with super-poissonian noise. Both effects are destroyed by fast relaxation processes. The non-monotonic behavior of the shot noise as a function of bias and relaxation rate reflects the details of the electronic structure and level-dependent coupling strengths.

Ananthakrishnana Bhatti, 1967: 22. Type species Ananthakrishnana indica Bhatti, 1967, by monotypy. Syn.n.
Bhatti distinguished his new genus solely on the basis that the postocular setae were exceptionally short for a Haplothrips species. Subsequently, in synonymising his species indica with euphorbiae, Bhatti (1979) added as distinguishing states for Ananthakrishnana the sexual dimorphism of the maxillary stylet position, and the unusually reticulate sculpture on the vertex. Sexual dimorphism in the position of maxillary stylets is now known to occur among various unrelated species of Haplothrips (Dang & Mound 2023). Similarly, reduction in length of the postocular setae also occurs in different species of Haplothrips (Mound 2024), including Haplothrips leucanthemi that is widespread across the Holarctic in the flowers of Ox-eye Daisies, Chrysanthemum leucanthemum. The third character state, the presence of sculpture lines on the vertex, also occurs in other species of Haplothrips. As a result, there seems to be no justification for considering euphorbiae as representing a lineage independent from other Haplothrips species, and Ananthakrishnana is here placed into synonymy.

description: We investigate the reflection coefficient of spin waves propagating in an ultra-thin ferromagnetic film with regions where saturation magnetization is modulated. We find analytically and using micromagnetic simulations that there are transmission resonances that depend on the width of the regions and on the energy of excitation. Our results resemble the quantum mechanical Ramsauer-Townsend effect in which an electron with certain energies can propagate above a potential field without scattering. Our findings are useful for reconfigurable magnonic devices where the saturation magnetization can be dynamically controlled via a thermal landscape.

Its construction is based on a novel idea of PET tomography based on plastic scintillators and wavelength shifter (WLS) and a new concept of positronium imaging. We have prepared a simulation program based on Monte Carlo methods for optimizing the geometry and material of the J-PEM prototype. Here we present the first results from the simulations and a brief review of the state of art of breast imaging modalities and their characteristics motivating our investigation.

description: Business system and business processes are not the same, but diametrically complex categories, consisting of a number of subsystems and sub-processes that require a partial analysis of the integrated process of establishing and improving business efficiency. Directions for use economic - investment of resources based on a rational process of selection they are specified, or “changes that occur in the choice depending on the changing circumstances of which depends on the choice.” Referenced implies acceptance of the fact that the process of investment represents an irreversible process, making inadequate use of limited resources means “stumbling block”, especially in a situation when it is applied in the process of revitalizing the weakened operating system. In accordance with previously observed and the facts stated, based on appropriate mathematical models and statistical valid economic laws, it is possible to check the reality of the business vision, formulating appropriate exit strategy and its implementation in a dynamic business environment. “Hence, the strategists sought, except that vision and has the ability to learn and synthesis, or masterstroke (crafting) strategies accordingly curve experience and new circumstances and lessons learned.”

Gloeodontia halocystidiata

description: Gloeodontia halocystidiata Gorjón sp. nov.
 Species ab aliis congeneribus affinis sed differt frequentia halocystidiorum.
 Etymology: — halus (Latin), referring to the halo present in the apex of some cystidial elements.
 Type: — BRAZIL. Roraima: Alto Alegre - Amajari, Maracá Ecological Station, 26 Sep 2008, on dead trunks, leg. M.A. Jesus, LPM 4631 (holotypus).
 MycoBank: MB 800945
Basidiome resupinate, effused, hymenophore creamish brown, odontioid with conical to flattened aculei, margin not differentiate. Hyphal system dimitic, generative hyphae with clamps, 2–3 µm in diam., skeletal hyphae thick-walled, 2–4 µm in diam., smooth or encrusted, hyaline or yellowish brown. Gloeocystidia long tubular, walls slightly thickened towards the base, variable in length up to 100–120 µm, 5–8 µm in diam., apex obtuse or with a schizopapilla, with oily contents in KOH, yellowish in Melzer’s reagent. Skeletocystidia arising from skeletal hyphae, variably encrustated with hyaline crystals, usually 30–40 × 6–8 µ m. Halocystidia with a resinous brown globule about 8–12 µm in diam. Core of aculei mainly composed of skeletal hyphae and halocystidia while the hymenium on aculei is formed as a palisade of gloeocystidia and basidia. Skeletocystidia occurs primarily at the base of the aculei or the hymenium between the aculei. Basidia clavate, 10–15 × 3–4 µm, with four sterigmata, and a basal clamp. Basidiospores ovoid to ellipsoid, 3.5–4 × 2–2.5 µm, thin-walled, seemingly smooth or slightly rugose, ornamentations difficult to observe, amyloid (Figs. 6, 7, 19).
 The species is characterized by an odontioid hymenophore, dimitic hyphal system, presence of gloeocystidia and encrusted skeletocystidia, and above all by the presence of halocystidia capped with a globule of brown resinous matter. Halocystidia are easily distinguishable elements in the core of the aculei. Gloeodontia Boidin seems to be the appropriate genus considering macro- and micromorphology, even though halocystidia were not described in the genus. Presence of halocystidia can be regarded as a variation at the species level as it occurs in some species of other corticioid genera like Peniophorella P. Karst., Resinicium Parmasto or Hyphodontia sensu lato J. Erikss.

description: Credit risk management is a major activity of each financial institution. Since the credit risk is most important cause of the bankruptcy of many banks, it`s been given a special attention. In addition to identifying, locating, measuring, as the final activity in тхе credit risk management arises hedging credit risk. Рrotection from unwanted credit risk is archieved by transfer of risk to the one who is willing to accept the same. In this paper are presented modern credit risk transfer instruments which are analized, in order to protect the capital of financial institution.

description: The Young Suns Exoplanet Survey (YSES) consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus association with an average age of $15\pm3\,$Myr. We report the detection of a co-moving companion around the K3IV star TYC 8998-760-1 (2MASSJ13251211-6456207) that is located at a distance of $94.6\pm0.3\,$pc using SPHERE/IRDIS on the VLT. Spectroscopic observations with VLT/X-SHOOTER constrain the mass of the star to $1.00\pm0.02\,M_{\odot}$ and an age of $16.7\pm1.4\,$Myr. The companion TYC 8998-760-1 b is detected at a projected separation of 1.71'', which implies a projected physical separation of $162\,$au. Photometric measurements ranging from $Y$ to $M$ band provide a mass estimate of $14\pm3\,M_\mathrm{jup}$ by comparison to BT-Settl and AMES-dusty isochrones, corresponding to a mass ratio of $q=0.013\pm0.003$ with respect to the primary. We rule out additional companions to TYC 8998-760-1 that are more massive than $12\,M_\mathrm{jup}$ and farther than $12\,$au away from the host. Future polarimetric and spectroscopic observations of this system with ground and space based observatories will facilitate testing of formation and evolution scenarios shaping the architecture of the circumstellar environment around this 'young Sun'.

Subjects: subject: Financial Economics
subject: accumulated sum
subject: annuity accumulation phase
subject: the phase of capital

description: Policyholders who are in the years before retirement and are intending to use the accumulated sum on pension accounts to purchase an annuity are the most sensitive category with regard to fluctuations in the capital market. It is that the policyholders of such profiles have been hardest hit by the latest economic crisis that led the collapse of stock market indices. For a successful asset management of pension funds it is important to define the stage of capital accumulation and phase of its preservation. Accumulation phase involves the accumulation of capital securities with potentially high returns, while the phase of capital preservation is based on risk-free debt securities of the highest rating. Actions taken during the phase of capital accumulation as well as the optimal moment of transition in the phase of its conservation are of vital importance for the amount of the accumulated sum that will be taken at the time of retirement.

description: The paper presents the role of global corporations in the modern economic - political world. Without getting into the legal form of organization of international companies on the role of institutions in creating a new, global world. Global corporations have entered into all sectors of the economy, especially in those that are technologically and financially cost-effective, such as the software industry, pharmaceutical, oil and petrochemical industries, banking and the all financial service sector. Due to the increasingly oligopolistic and even monopolistic positions in certain markets, global corporations are the target of economic analysts, thus creating a somewhat distorted picture of reality. Since their business is based on very scattered but dependent coordinated structure of branches and most of all a huge capital sometimes, consciously or not, violates the basic laws of economy. Global corporations are the creators of global changes and as such have a great influence on the adoption of economic, political and other decisions of sovereign states. In order to safeguard its position in the market sometimes ignores national laws and violate the basic rules of business, by offering bribes to civil servants and officials. Establishing communication with the countries in which they are present, with global institutions, political parties deliberately developed a new form of nonstate diplomacy. Corporate diplomacy as a product of global corporate activity is increasingly gaining in importance and becomes a subject of research and study.

description: We present the particular case of the Stephani solution for shear-free perfect fluid with uniform energy density and non-uniform pressure. Such models appeared as possible alternative to the consideration of the exotic forms of matter like dark energy that would cause the acceleration of the universe expansion. These models are characterised by the spatial curvature depending on time. We analyze the properties of the cosmological model obtained on the basis of exact solution of the Stephani class and adopt it to the recent observational data. The spatial geometry of the model is investigated. We show that despite possible singularities, the model can describe the current stage of the universe evolution.
