Local landscape evolution related to human impact of an early medieval pre-urban center in the Upper Dnieper region (Central Russian Plain): an interdisciplinary experience

Subatlantic landscape changes were reconstructed by correlating independent results of pedological studies, pollen, phytolith, and micropaleontological analyses of flood plain soil-sedimentary and sedimentary sections in the Upper Dnieper region within an early medieval pre-urban center and in its close vicinities. Major phases of Subatlantic landscape evolution were defined as follows. A phase of low and dispersed human impact (approximately 3,000 BP–1,100 BP) is remarkable by widespread zonal forest ecosystems and periodic slight increases of cultivated plants and others favored by culture. The phase included a stage of active floodplain sedimentation changed by a drier period (not earlier than 2,400 BP) of no sedimentation and formation of Luvisols in the floodplain. The next phase of intensive local human impact occurred during early medieval settlement (1,100–1,000 BP) and is characterized by extensive deforestation, wide introduction of variable human-related plants and deep transformation of original soils within the settlement’s area: formation of Urbi-Anthropic Regosols. A phase of no local human impact but generally higher anthropogenic pressure in the region (later than 1,000 BP) started after a decline of the settlement. The number of settlements increased sharply in the region in the 11 th – 13 th centuries. This caused extensive anthropogenic deforestation and re-establishment of human impact indicators after a slight forest invasion and sharp but short drop in humanrelated plants. Floodplain sedimentation sharply increased. Garbi-Urbic materials of the settlement and Luvisols beyond the settlement’s borders were buried under floodplain alluvium about 1,000– 800 BP. At the end of this phase, formation of contemporary Fluvisols took place due to declining sedimentation rates (200–150 BP).
School of Chemical Technology Degree Programme of Forest Products Technology Sami Mäkinen WHICH RECOMMENDATION TYPE IS MOST LIKELY TO LEAD TO PURCHASE ONCE CLICKED? Master’s thesis for the degree of Master of Science in Technology

Wide variety of surveys have studied recommendation systems (RS) and the topic is very current. However, the general research topics are related on what algorithm is the best or how algorithms differ from each other and what happens if different algorithms are combined. Also customers’ attitudes and trust (including privacy issues) toward RS are surveyed. This study investigates what happens after a certain (history-related, item-related or toplist) recommendation type is clicked, which will produce the most carted items and the most importantly purchased items. The data used was from a company providing recommendation services for online stores, thus the company sells only the recommendation service itself. The data was from a real life web store providing very valuable and rare knowledge. Because of the company’s clients’ privacy policy, the source of data was not known. Known is that the web store was large European store and most customers were European too. An important remark is that the data was gathered only from one web store and included one million single sessions. The data was studied and linear regression models were contributed. Also binary mode format was used to exclude certain occasions. Results gave some strong indications that there is a notable difference between recommendation types. Results were also connected with a literature findings and psychological persuasion, informative persuasion and clickstream behavior were discussed. The history type was clearly the most effective recommendation type. Item related recommendation was the second most effective. The reason of the difference is the better and more precise knowledge of the user for the history related recommendation. Toplist was clearly the weakest type to provide purchased items. It is totally impersonal, so the informative aspect is very low, only providing knowledge of popular items. Findings suggest that everything is based on to the knowledge of the user. More accurate recommendations will provide more purchases. As mentioned the amount of recommendation researches is very large, yet certain areas are unexpectedly unstudied. More attention should be assigned to practical side of the recommendations and as this study suggests it can provide a great benefit.
Semantic radicals in Japanese two-character word recognition

Extending previous studies on sub-lexical character constituent activation in Japanese and Chinese, the present regression study investigates whether recognition of two-character words in Japanese involves activation of semantic radicals and whether the semantic radicals’ contribution is orthographic or semantic in nature. A mixed-effects model complemented with a random forest analysis provided support for the importance of the semantic radical, as witnessed by two orthogonal sets of semantic radical properties: the radicals’ semantic transparency and usefulness, as well as the semantic radicals’ combinability and token frequency. The two frequency effects were facilitatory for the head of the compound, but inhibitory for the modifier, possibly due to incompatibility of the semantic class marked by the modifier's radical with that of the compound as a whole. Thus, semantic radicals emerge as not just orthographic components but as fully fledged purely orthographic morphemes.
Title: IMPACT OF -AMYLASE DURING BREADMAKING ON IN VITRO 3 KINETICS OF STARCH HYDROLYSIS AND GLYCAEMIC INDEX OF ENRICHED

18 Nowadays, the use of enzymes has become a common practice in the bakery industry, as 19 they can improve dough quality and texture of final product. However, the use of α20 amylases could have a negative effect in the glycaemic load of product, due to the 21 released sugars from the starch hydrolysis that are not used by yeasts during the 22 fermentation process. This study evaluated the effect of the addition of α-amylase in 23 bakery products with bran on in vitro kinetics of starch hydrolysis. The use of flour with a 24 high degree of extraction or high bran amount could decrease the GI even with the 25
Media Exposure, Aggression and Prosocial Behavior During Early Childhood: A Longitudinal Study

Preschool children (N = 78) enrolled in multi-informant, multi-method longitudinal study were participants in a study designed to investigate the role of media exposure (i.e., violent and educational) on concurrent and future aggressive and prosocial behavior. Specifically, the amount of media exposure and the nature of the content was used to predict concurrent and future physical, verbal and relational aggression as well as prosocial behavior for girls and boys. This two-year longitudinal study found that media exposure predicted various subtypes of aggression and prosocial behavior. These findings are qualified by the gender of the focal child. That is, parental reports of media exposure were associated with relational aggression for girls and physical aggression for boys at school. Ways in which these findings extend our understanding of the role of media during early childhood are discussed.
PERSONALITY PROCESSES AND INDIVIDUAL DIFFERENCES Positive Affect, Intuition, and Feelings of Meaning

Subjective rationality, or the feeling of meaning, was identified by William James (1893) as a central aspect of the non-sensory fringe of consciousness. Three studies examined the interaction of positive affect (PA) and individual differences in intuitive information processing in predicting feelings of meaning for various stimuli and life events. In Study 1 (N 352), PA and intuition interacted to predict understanding for ambiguous quotes and abstract artwork. In Study 2 (N 211), similar interactions were found for feelings of meaning for fans after their football team lost a conference championship game and for individuals not directly affected by Hurricane Katrina in events surrounding the hurricane. In Study 3 (N 41), induced PA interacted with individual differences in intuition in predicting accuracy for coherence judgments for loosely related linguistic triads. Intuitive individuals in the positive mood condition recognized coherent triads more accurately than did other participants. Results are discussed in terms of the role of individual differences in intuitive information processing in the relationship of PA to cognition.
Fluctuations, Escape, and Nucleation in Driven Systems: Logarithmic Susceptibility

We analyze the probabilities of large infrequent fluctuations in nonadiabatically driven systems. In a broad range of the driving field magnitudes, the logarithm of the fluctuation probability is linear in the field, and the response can be characterized by a logarithmic susceptibility (LS). We evaluate the activation energies for nucleation, with account taken of the field-induced lifting of time and spatial degeneracy of instantonlike nucleation trajectories. LS for nucleation in systems with nonconserved order parameter is shown to be a nonmonotonic function of v and k. [S0031-9007(97)04328-7]
Signal delay in linear leaky RC mesh/tree

As chip dimensions are reduced, the performance of integrated circuits is limited by the delays associated with the interconnections. For the purpose of propagation delay estimation in digital circuits, these interconnections can be modelled by leaky RC tree/line/mesh. Signal delay in a nonleaky RC tree can be estimated by a tree algorithm. In this paper a modified tree algorithm (linear order) is presented for estimating signal delay in a leaky RC tree with nonzero initial conditions. <<ETX>>
A numerical study of the Navier–Stokes transport coefficients for two-dimensional granular hydrodynamics

A numerical study that aims to analyze the thermal mechanisms of unsteady, supersonic granular flow by means of hydrodynamic simulations of the Navier–Stokes granular equation is reported in this paper. For this purpose, a paradigmatic problem in granular dynamics such as the Faraday instability is selected. Two different approaches for the Navier–Stokes transport coefficients for granular materials are considered, namely the traditional Jenkins–Richman theory for moderately dense quasi-elastic grains and the improved Garzó–Dufty–Lutsko theory for arbitrary inelasticity, which we also present here. Both the solutions are compared with event-driven simulations of the same system under the same conditions, by analyzing the density, temperature and velocity field. Important differences are found between the two approaches, leading to interesting implications. In particular, the heat transfer mechanism coupled to the density gradient, which is a distinctive feature of inelastic granular gases, is responsible for a major discrepancy in the temperature field and hence in the diffusion mechanisms.
Adaptation in Mandarin tone production with pitch-shifted auditory feedback: influence of tonal contrast requirements

ABSTRACT We investigated Mandarin speakers’ control of lexical tone production with F0-perturbed auditory feedback. Subjects produced high level (T1), mid rising (T2), low dipping (T3), and high falling (T4) tones in conditions with (a) no perturbation, (b) T1 shifted down, (c) T1 shifted down and T3 shifted up, or (d) T1 shifted down and T3 shifted up but without producing other tones. Speakers and new subjects also completed a tone identification task with unaltered and F0-perturbed productions. With only T1 perturbed down, speakers adapted by raising F0 relative to no-perturbation. With simultaneous T1 down and T3 up perturbations, no T1 adaptation occurred, and T3 adaptation occurred only if T2 was also produced. Identification accuracy with stimuli representing adapted productions was comparable to baseline, but with simulated non-adapted productions it was reduced for T2 and T3. Thus, Mandarin speakers’ adaptation to F0 perturbations is linguistically constrained and serves to maintain tone contrast.
A MUlti-Sensory Language Interface

While the expansion of worldwide hypermedia systems has opened new gateways in the information industry, the result has been material being archived faster than it can be read. Users need to be able to scan information quickly and have more control in information seeking and retrieval. A new area of research is in the development of multimedia tools that answer these needs. One of the aims in the development of MUSLI (MUlti Sensory Language Interface) is to integrate dynamic abstract symbolism into hypermedia technology (linked multimedia documents embedded in a network) , allowing for more efficient information retrieval and communication. In a MUSLI movie, users can stop and display additional information as they need ani skim condensed versions of a document, searching for relevant sections before breaking down the symbols to display pertinent information. MUSLI documents incorporate material processes ("doing"), mental processes ("sensing"), and relational processes ("being"); these processes are brought together with dynamic symbols. The proposed system will be flexible enough to blend traditional forms of documentation into modern multimedia information retrieval systems while gradually becoming enriched with its own symbolic language.

1.01-Pb/s (12 SDM/222 WDM/456 Gb/s) Crosstalk-managed Transmission with 91.4-b/s/Hz Aggregate Spectral Efficiency

Abstract (40-Word Limit): We demonstrate 1.01-Pb/s transmission over 52 km with the highest aggregate spectral efficiency of 91.4 b/s/Hz by using low-crosstalk one-ring-structured 12-core fiber. Our multi-core fiber and compact fan-in/fan-out devices are designed to support high-order modulation formats up to 32-QAM in SDM transmission.
Double Blind Separation of Compressively Sensed Signals

This work focuses on the problem of jointly separating and reconstructing source signals from compressively sensed mixtures. The proposed approach combines the concept of blind compressive sensing (BCS) with the model of blind source separation (BSS). Specifically, the unknown source signals are assumed to admit some sparse representations with respect to an unknown dictionary. We propose an appropriate cost function for the problem together with an alternating minimization scheme for finding a solution. A fixed-point analysis as well as experiments on synthetic and on real data will be provided to demonstrate the efficiency and the convergence behavior of the proposed algorithm.
Antiferromagnetic order in 
CaK(Fe1−xNix)4As4
 and its interplay with superconductivity

The magnetic order in CaK(Fe[1-x]Ni[x])4As4 (1144) single crystals (x = 0.051 and 0.033) has been studied by neutron diffraction. We observe magnetic Bragg peaks associated to the same propagation vectors as found for the collinear stripe antiferromagnetic (AFM) order in the related BaFe2As2 (122) compound. The AFM state in 1144 preserves tetragonal symmetry and only a commensurate, non-collinear structure with a hedgehog spin-vortex crystal (SVC) arrangement in the Fe plane and simple AFM stacking along the c direction is consistent with our observations. The SVC order is promoted by the reduced symmetry in the FeAs layer in the 1144 structure. The long-range SVC order coexists with superconductivity, however, similar to the doped 122 compounds, the ordered magnetic moment is gradually suppressed with the developing superconducting order parameter. This supports the notion that both collinear and non-collinear magnetism and superconductivity are competing for the same electrons coupled by Fermi surface nesting in iron arsenide superconductors.
MODELING METHODS FOR THE HIGHLY DISPERSIVE SLINKY SPRING: A NOVEL MUSICAL TOY

The ’Slinky’ spring is a popular and beloved toy for many children. Like its smaller relatives, used in spring reverberation units, it can produce interesting sonic behaviors. We explore the behavior of the ’Slinky’ spring via measurement, and discover that its sonic characteristics are notably different to those of smaller springs. We discuss methods of modeling the behavior of a Slinky via the use of finite-difference techniques and digital waveguides. We then apply these models in different structures to build a number of interesting tools for computer-based music production.
A fluid queue with a finite buffer and subexponential input

We consider a fluid model similar to that of Kella and Whitt [32], but with a buffer having finite capacity K. The connections between the infinite buffer fluid model and the G/G/1 queue established by Kella and Whitt are extended to the finite buffer case: it is shown that the stationary distribution of the buffer content is related to the stationary distribution of the finite dam. We also derive a number of new results for the latter model. In particular, an asymptotic expansion for the loss fraction is given for the case of subexponential service times. The stationary buffer content distribution of the fluid model is also related to that of the corresponding model with infinite buffer size, by showing that the two corresponding probability measures are proportional on [0,K) if the silence periods are exponentially distributed. These results are applied to obtain large buffer asymptotics for the loss fraction and the mean buffer content when the fluid queue is fed by N On-Off sources with subexponential on-periods. The asymptotic results show a significant influence of heavy-tailed input characteristics on the performance of the fluid queue.
Design of Low-Power Temperature Sensor Architecture for Passive UHF RFID Tags

A low-power wide-range CMOS temperature sensor architecture is proposed based on temperature-to-frequency conversion using supply voltage controlled sub-threshold ring oscillator. The principles of operation are investigated and proved via analytic and simulation results. Most errors are canceled out by this ratio-metric design. An inaccuracy of -0.84°C to +0.34°C occurs over a range of -40°C to 80°C after using a novel in-field digital two-point calibration. The entire sensor consumes less than 93nW to 305nW over the temperature range and can be digitally reconfigured for setting sample rate and resolution in a tradeoff.
Invited reaction: Managing workplace incivility: The role of conflict management styles—antecedent or antidote?

Research examining the relationship between incivility and conflict management styles is sorely lacking. This is surprising, given the natural fit between these two research streams. That is, it seems prudent to draw on knowledge gleaned from the vast conflict management literature to help inform the workplace mistreatment literature and to provide potential solutions for dealing with workplace incivility. In this issue, Trudel and Reio (2011) aim to redress this gap in the literature by investigating the relationship between workplace incivility and conflict management styles. This is a commendable and important first step to bridge the ideas from these two literatures. We comment on this study by providing our assessment of the contributions of the study and by addressing some concerns about both the study itself the broader issues in the field. We also provide some suggestions for further research in this area. In their study, Trudel and Reio asked two broad research questions: 1. Which conflict management styles make people more likely to engage in uncivil behaviors? 2. Which conflict management styles make one more likely to be the target of uncivil behaviors? The study found that after controlling for gender, hierarchical position, and organization, two of the conflict management styles are related to both enacting and being the target of incivility. Specifically, persons with an integrative style (i.e., those who seek a win–win solution to conflicts) are both less likely to instigate incivility and less likely to be targets of incivility. In contrast, those with a dominating style (i.e., those who are highly concerned with their own goals while exhibiting little concern for the goals of others)
Cyber Panel Experimentation Program

Abstract : This CyberPanel Experimentation Program final report describes two experiments: (1) an experimental validation of correlation systems as well as (2) a validation of autonomic response systems. The goal of this effort was to assess the overall progress in the field by separately measuring the aggregate correlation efficacy and response capabilities of seven distinct research technologies. The network supported planning activities critical to a hypothetical military mission and supported modeled user activity such as email and web browsing. Each enclave was defended by security devices implementing a defined security policy and by various intrusion detection sensors. A variety of multi-step cyber attacks were perpetrated against the target network each of which typifies a current-day real-world attack. The preliminary results presented here represent those available at conclusion of the experiment process by BBN.
Asynchronous ratcheted key exchange

Ratcheted key exchange (RKE) is a cryptographic technique used in instant messaging systems like Signal and the WhatsApp messenger for attaining strong security in the face of state exposure attacks. RKE received academic attention in the recent works of Cohn-Gordon et al. (EuroS&P 2017) and Bellare et al. (CRYPTO 2017). While the former is analytical in the sense that it aims primarily at assessing the security that one particular protocol does achieve (which might be weaker than the notion that it should achieve), the authors of the latter develop and instantiate a notion of security from scratch, independently of existing implementations. Unfortunately, however, their model is quite restricted, e.g. for considering only unidirectional communication and the exposure of only one of the two parties. In this article we resolve the limitations of prior work by developing alternative security definitions, for unidirectional RKE as well as for RKE where both parties contribute. We follow a purist approach, aiming at finding strong yet convincing notions that cover a realistic communication model with fully concurrent operation of both participants. We further propose secure instantiations (as the protocols analyzed or proposed by Cohn-Gordon et al. and Bellare et al. turn out to be weak in our models). While our scheme for the unidirectional case builds on a generic KEM as the main building block (differently to prior work that requires explicitly Diffie–Hellman), our schemes for bidirectional RKE require a stronger, HIBE-like component.
