The Problem of Alternative Financing Source Management – The Equity Crowdfunding Case
Authors: Motylska-Kuźma Anna 
Published: January 2020

Abstract
The main objective of this paper is to analyze one of the alternative sources of financing - equity crowdfunding - from the point of view of managerial processes. Based on the case study analysis and the comparative analysis the problems and challenges of raising funds using equity crowdfunding are discussed, comparing the findings with the issuing of shares. The analysis show that although many of the activities undertaken in raising funds through issuing shares and equity crowdfunding are similar, the managerial processes in the case of equity crowdfunding require from the company first of all building and caring about relationships with investors, rather than showing and proving effectiveness. In exchange for the low legal requirements, the equity crowdfunding investors expect good communication even if the promises are not fulfilled.
Misinformation About Dividend Payouts Influences Transaction Prices in Experimental Asset Markets
Authors: Polak Mateusz , Polczyk Romuald 
Published: January 2020

Abstract
AIMS: The paper investigates the effects of misinformation regarding dividend payouts on bubble formation, asset pricing and individual investment returns in experimental asset markets, when correct information about the expected dividends and their probabilities is also available.
METHOD: In two experiments, totaling34 Smith-Suchanek-Williams type double-auction continuous experimental markets (238 subjects), participants were exposed to misinformation regarding dividend payouts in a previous game, with the correct dividend matrix also provided. The misinformation stated the dividends in the previous game to have been much lower or much higher than according to the expected value function. The misinformation was either homogenous for all participants or provided to only half of the investors in a market (heterogeneously).
RESULTS:Homogenous misinformation stating that the last game’s dividend payouts were high, led to larger overpricing throughout the game, as compared to baseline (no misinformation) and homogenous misinformation stating that the last game’s dividends were low. In informationally heterogeneous markets, where half of the participants received “high dividends” misinformation and half remained non-misinformed, transaction prices were the lowest compared to the aforementioned treatments. It was also discovered that agents receiving the ‘high dividend’ misinformation had lower returns than non-misinformed participants in the same heterogeneous market.

Methodology of reconstruction of the Old-Polish road network as exemplified by the historic Lublin Voivodship
Authors: Zawadzki Mateusz 
Published: January 2020

Abstract
The aim of the author is to present the methodology of reconstruction of the Old-Polish transport network as exemplified by the historic Lublin Voivodship. The author discusses the research method and procedure of reconstructing the road routes and locations of transport facilities on the basis of text sources and old maps of varied content and geometric accuracy. The adopted methodology uses GIS tools to analyse and verify data from both cartographic and descriptive sources. The analysis is based on the retrogressive approach, as most of the cartographically reliable sources come from the early 19th century.
The presented research procedure consists of three stages: preparation and processing of source material, registration of source information, and finally, its harmonization. The research procedure consists of two main steps: 1) identification (initial identification of the object and verification of its existence); 2) geometrisation (determination of geometrical parameters of the object, followed by their verification, and confirmation of the object’s course or location in the spatial database).
Equilibrium, kinetic and thermodynamic studies on methylene blue adsorption by Trichosanthes kirilowii Maxim shell activated carbon
Authors: Wang Yuqi , Li Yanhui , Zheng Heng 
Published: January 2020

Abstract
New kind of adsorbent was produced from Trichosanthes kirilowii Maxim shell. The KOH activation technology for preparation of Trichosanthes kirilowii Maxim shell activated carbon (TKMCK) was optimized. Using methylene blue as the sample adsorbate, the adsorption behavior was systematically investigated in terms of the activation agent and temperature, the adsorption temperature and time, the initial adsorbate pH and concentration, as well as the dosage of adsorbent. Surface physical morphology of the TKMCK prepared was observed by scanning electron microscopy (SEM), while the functional groups were determined with Fourier transform infrared (FTIR) spectra. Kinetic studies indicated that the adsorption process was more consistent with the pseudo-second-order kinetic. Both Langmuir and Freundlich isotherms were employed to fit the adsorption data at equilibrium, with the former giving a maximum adsorption capacity of 793.65 mg/g at 323 K. BET surface area of as-prepared TKMCK was 657.78 m2/g.

Published: January 2020

Abstract
This paper focuses on protecting the cellular paging protocol — which balances between the quality-of-service and battery consumption of a device — against security and privacy attacks. Attacks against this protocol can have severe repercussions, for instance, allowing attacker to infer a victim’s location, leak a victim’s IMSI, and inject fabricated emergency alerts. To secure the protocol, we first identify the underlying design weaknesses enabling such attacks and then propose efficient and backward-compatible approaches to address these weaknesses. We also demonstrate the deployment feasibility of our enhanced paging protocol by implementing it on an open-source cellular protocol library and commodity hardware. Our evaluation demonstrates that the enhanced protocol can thwart attacks without incurring substantial overhead.
Black-Box Wallets: Fast Anonymous Two-Way Payments for Constrained Devices

Published: January 2020

Abstract
Black-box accumulation (BBA) is a building block which enables a privacy-preserving implementation of point collection and redemption, a functionality required in a variety of user-centric applications including loyalty programs, incentive systems, and mobile payments. By definition, BBA+ schemes (Hartung et al. CCS ‘17) offer strong privacy and security guarantees, such as unlinkability of transactions and correctness of the balance flows of all (even malicious) users. Unfortunately, the instantiation of BBA+ presented at CCS ‘17 is, on modern smartphones, just fast enough for comfortable use. It is too slow for wearables, let alone smart-cards. Moreover, it lacks a crucial property: For the sake of efficiency, the user’s balance is presented in the clear when points are deducted. This may allow to track owners by just observing revealed balances, even though privacy is otherwise guaranteed. The authors intentionally forgo the use of costly range proofs, which would remedy this problem.
We present an instantiation of BBA+ with some extensions following a different technical approach which significantly improves efficiency. To this end, we get rid of pairing groups, rely on different zero-knowledge and fast range proofs, along with a slightly modified version of Baldimtsi-Lysyanskaya blind signatures (CCS ‘13). Our prototype implementation with range proofs (for 16 bit balances) outperforms BBA+ without range proofs by a factor of 2.5. Moreover, we give estimates showing that smart-card implementations are within reach.

Published: January 2020

Abstract
The study is focused on the mechanical behavior and finite element method (FEM) modeling of glued timber dowel connections with slotted-in steel plates. Standard tests accompanied by a physical optics investigation method were used in order to obtain information about the mechanical properties and stress-strain behavior of glued timber dowel connections with slotted-in steel plates. As such a methodology provides information on the stress-strain state over the surface of a connection, it was used as a verification criterion for a 3D finite-element model. Small-scale glued timber dowel connections with slotted-in steel plates were tested in parallel-to-grain tension to investigate their load-carrying capacity and the load-slip performance of the connection. A three-dimensional finite-element model of the glued timber dowel connections with slotted-in steel plates was developed using existing FE software and verified using the holographic interferograms obtained during step-by-step loading as well as the test results.

Amphibole and biotite of melanocratic rocks from the Ural granitic massifs: composition, relationship, petrogenetic consequences
Authors: Pribavkin S. V. 
Published: January 2020

Research subject. The article discusses the features of the relationship between biotite and amphibole on the example of magmatogene melanocratic rocks from a number of granitoid massifs of the Urals. These rocks form xenoliths and synplutonic intrusions of the calc-alkaline series of normal alkalinity: gornblenditam, gabbro, diorite, quartz diorite. They are composed of amphibole, acidic or middle plagioclase, in a subordinated quanitity they contain clinopyroxene, biotite, potassium feldspar, quartz.Materials and methods. The composition of the minerals of melanocratic rocks was determined on a JSM-6990LV electron microscope with an EDC-adapter of INCA Energy 450 X-Max 80 in the Geoanalytical Center of the IGG Ural Branch of the Russian Academy of Sciences.Results and conclusions. Wide variations in amphibole compositions and narrow biotite variations caused by exchange processes between the mineral and postmagmatic fluid are shown. The phenomenon of replacement of early magmatic amphibole with biotite is substantiated by the presence of a gap in the crystallization temperatures of minerals, indicating a lack of physicochemical equilibrium between them. Their structural relationships confirm the development of biotite as a result of the replacement of amphibole in accordance with the competent and incompetent phase boundaries. In the first case, the structural packets of biotite are embedded along the silicon-oxygen chains of amphibole, which is expressed in the parallelism of the (001) plane of biotite with the (100), (110) planes of amphibole. In the second case, the development of biotite occurs irregularly, inheriting the system of cracks in amphibole. The distribution of Mg/Fe between biotite and early magmatic amphibole was studied, showing that the magnesia value of biotite is higher than that of amphibole replaced by it. Inverse ratios of magnesia value occur between biotite and post-magmatic amphibole. The equality of the magnesia values of both minerals may reflect the conditions of subsolidus equilibration of the compositions. The problem of choosing amphibole compositions for calculating the PTparameters of the formation of massifs in the Earth crust is considered.

Research subject. The article presents the results of a microscopic and photogoniometric study of natural rounded diamonds of tetraghexahedral habit from the kimberlite pipe “Internationalnaya” (Yakutia). The diamonds was partially dissolved in a sulphur-containing iron melt (sulphur content of 15–30 wt %) at 4.5 GPa and 1450ºС.Methods. The experiments were carried out on a multi-puncheon apparatus of a “split-sphere” type in high-pressure solid-phase cells made of refractory oxides ZrO2, CaO, MgO using a cylindrical shape graphite heater. The crystals were studied using an MBS-10 optical microscope with a photo camera, and a Jeol JSM-6510LV scanning electron microscope. A goniometric study of diamond crystals was carried out by a photo method in a cylindrical chamber. It was found that when a sulphur content was 15 wt %, diamond crystals of tetrahexahedral habit were transformed into a curved shaped octahedroids with morphological features similar to natural diamonds found in kimberlites. When the sulphur content was 23–30 wt %, the rate of dissolution of diamonds in the Fe-S melt sharply reduced, while the diamond surface at the micro level became covered with numerous etching hillocks, whose sidewalls have surfaces similar to flat-faced {111} form. Dissolution of the rounded diamonds in the Fe-S melt at high pressure occurred by a “normal” mechanism, that is perpendicular to the surface of the dissolving crystal through trigonal dissolution layers, while a tangential-layered mechanism played a minor role.Conclusion. The natural diamond crystals could underwent dissolution in the mantle before they were captured by kimberlite magma. Two fundamentally different types of homomorphic and typomorphic features of the dissolution forms observed on natural diamonds can be determined, namely: on one side, those associated with storage in mantle before the crystals were captured by the kimberlite magma, and on the other side, with the kimberlite process itself. The presence of octahedral diamonds with parallel (trigonal) striation in kimberlite deposits may indicate on a high degree of diamond preservation due to relatively insignificant effect of the kimberlite magma. This, undoubtedly, should help to decipher the diamond genesis and, possibly, improve the mineralogical criteria used in diamond exploration.
