Life and death in the Neolithic variscite mines at Gavà (Barcelona, Spain)

Abstract Mining has commonly been thought of as hard manual labour undertaken by the lower echelon of a hierarchical society, but was this always the case? Recent excavations of the variscite mines at Gavà have revealed burials contemporary with the peak of mining activity that represent a community of miners exploiting the subterranean resources for trade and manufacturing variscite beads with a nuanced symbolism. Skeletal evidence demonstrates the physicality of mining while grave goods reveal a community that worked collectively to mine, manufacture and trade goods, with miners themselves benefiting from the fruits of their labours.
Dynamic Behavior of Terminal Sliding Mode Control

This paper proposes two new definitions and related theorems in analyzing the transient behavior of terminal sliding mode control (TSMC) for nonlinear systems. The first one is named critical trajectory (CT), which is used to characterize the system dynamics for both TSMC and its nonsingular version, i.e., nonsingular TSMC (NTSMC). The second one is named constrained surface (CS), which is used to characterize the phase trajectory for NTSMC. Based on these two terms, we further propose two new theorems and their associated rigorous proofs that can be used to comprehensively describe the dynamic behavior of TSMC and NTSMC. In addition to theoretical analyses, we also present two case studies, i.e., one numerical example and one two-link manipulator system, to verify the effectiveness of the proposed theoretical research.
Research On Hierarchical Data Visualization Based On the Shape Parallel Coordinates System

This paper presents a method of Shape Parallel Coordinates System for data visualization. First, the axis is defined in the plane and the set of the axes is called the main shape. The lines set used to constraint and cooperate with the main shape is defined as the vice shape. The coordinate system formed by using the auxiliary shape set to set axes layout is defined as Shape Parallel Coordinates System, which has good plane figures simulation and superposition. According to the data dimension and structure, we give the Shape Parallel Coordinates System generation algorithm (including the single Shape Parallel Coordinates System generation algorithm and Shape Parallel Coordinates System superposition algorithm) and Transform Data algorithm. Finally, by means of L-system, we achieve a kind of hierarchical data visualization based on the Tree Shape Parallel Coordinates System.
Romanized Language Identification and Transliteration System for Security with an Authentication System Using Persuasive Cued Click Points-RLITS

Romanized script is popular today for communication in every country, as the script is almost universally enabled in text processors. In countries like India which is a linguistic cauldron, it is very common to see English text in email messages and chat transcripts, with generous sprinkling of words from local languages in roman script. Dubbed as Manglish (Malayalam and English) etc., this roman transliteration of nonEnglish languages contributes to a major noise in analyzing English text in these countries. Our system, RLITS introduces an automated language identification scheme from the Romanized message with SVM regression. It also provides a facility to transmit our message securely using symmetric key cryptography. The overall system is protected by an authentication scheme persuasive cued click point.

On the offered skills in Heroes of Might and Magic III dimis January

In this document I will try to describe, to the best of my knowledge, the work and the results that are available online on problems related to the offered skills while leveling up a hero in HOMM-III. A new result is presented in section 4.4 as well as two unified tables with probabilities for hero classes; namely tables 3 and 4. Those that are interested in the problem might want to have a look on [9] which deals with a similar problem but is not within the scope of the document. 1 Instead of introduction I guess everyone who reads this document is familiar with the game Heroes of Might and Magic III (HOMM-III for short). If not, details are given in section A in the appendix. I will summarize, to the best of my knowledge, the work and the results that are available online about matters regarding skills, and skills offered during level-ups. For me everything started with the thread Heroes’ Stats and Skills Chances [11]. In that thread some weight tables were presented and are these weights that influence the skills that appear during level-ups. The way the weights are used for determining the offered skills is presented in section 2. Since we are dealing with a weight table, it is inevitable that we have some sort of randomness. However, practice indicates that heroes might get exactly the same skills as in a previous game. Therefore, the weight table alone is simply not enough to justify skill-advancing given that the implied state-space is huge [3]. That extra information we need is a model on how things work. More on that can be found in section 2. However, before I proceed I need a definition which is central throughout the document. Definition 1.1. Skill-advancing or (abusively) level-up is the process in which a hero gains one or more new skills. 1.1 Why is it important to know about skill-advancing? Perhaps the most significant part of the game is actually played on the way you level-up your (main) hero. The time that you accept or refute certain skills has an impact until the end of the game. And basically, all end-fights (as well as all previous fights against the map) are judged by the skills the main heroes have at that moment. Hence, the development of the heroes is the most crucial part of the game. This gives us a motive to spend our time with problems related to skill-advancing.
Opposite effects of cofilin and profilin from porcine brain on rate of exchange of actin-bound adenosine 5'-triphosphate.

Cofilin, an actin-binding protein isolated from porcine brain that reacts with actin in a 1:1 molar ratio [Nishida, E. , Maekawa, S. , & Sakai, H. (1984) Biochemistry 23, 5307-5313], decreases the rate of exchange of ATP bound to G-actin with 1,N6-ethenoadenosine 5'-triphosphate in solution. From analyses of the dependence of the exchange rate on the cofilin concentration under different KCl concentrations, dissociation constants (KD) for the cofilin-actin binding at 0, 50, and 140 mM KCl were determined to be 0.12, 0.15, and 0.25 microM, respectively. In contrast to cofilin, profilin isolated from porcine brain increases the rate of exchange of G-actin-bound ATP, like Acanthamoeba profilin. The kinetic analyses gave KD values for the profilin-actin binding of 1.1 and 1.5 microM, respectively, at 50 and 200 mM KCl.
Detecting Hidden and Exposed Terminal Problems in Densely Deployed Wireless Networks

In this paper, we discuss problems in densely deployed wireless networks. Particularly, we focus on wireless local area networks (WLANs) because they have enabled us to provide seamless and high capacity wireless access easily and inexpensively. However, recently, channel interference between different services has become a serious problem because access points (APs) of WLANs are located too densely. In the carrier sense multiple access with collision avoidance used in WLANs, the hidden terminal (HT) and the exposed terminal (ET) problems occur depending on the distance between stations and the carrier sensing range. In the higher dense deployment mentioned above, the HT and ET problems occur complicatedly. Therefore, we propose an AP cooperation system that detects the HT and ET problems between stations (STAs). In our system, APs are operated with time synchronization and obtain the information of connected STAs from received frames. The HT and ET problems are identified from the integration of the information obtained at different APs. The effectiveness is verified by simulations.
Rapid reactions of peroxynitrite with heme-thiolate proteins as the basis for protection of prostacyclin synthase from inactivation by nitration.

Prostacyclin (PGI(2)) synthase is a heme-thiolate (P450) protein which reacts with low levels of peroxynitrite (PN) under tyrosine nitration and inactivation. Studying heme proteins as models, we have found the heme-thiolate protein NADH-NO reductase (P450(NOR)) to be highly efficient in decomposing PN under concomitant nitration of phenol. The present study investigates two other P450 proteins, P450(BM-3) and chloroperoxidase, in order to test for the specific role of the thiolate ligand in the reaction with PN. A comparison with horseradish peroxidase and microperoxidase gives evidence of kinetic differences that classify heme-thiolate proteins, but not other heme proteins, as effective inhibitors of PGI(2) synthase nitration and inactivation. P450(BM-3) with PN catalyzes phenol nitration and nitration of its own tyrosine below 10 microM PN, whereas chloroperoxidase and P450(NOR) at such concentrations also nitrate phenol but not enzyme-bound tyrosine residues. We conclude that heme-thiolate proteins in general exhibit high reactivity with PN and turnover, probably due to the special electronic structure of the presumed thiolate-ferryl intermediate.
Fatigue perturbation of the os calcis.

This paper represents a philosophical shift in thinking. The authors propose that heel spur syndrome is not a primary soft tissue injury (i.e., enthesiopathy with concomitant bruising of the bursae and fat pad, and eventually the formation of a traction spur by the pull of the plantar fascia), but rather a primary bone injury. A microtrabecular stress failure (fatigue perturbation) of the os calcis occurs with secondary soft tissue involvement such as enthesiopathy, periostitis, myositis, bursitis, and finally the formation of a buttress callous (bone spur) to stabilize a microcortical crack. This study describes four stages in a progressive, sequential, pattern of fatigue failure of the os calcis. Clinical symptoms for each stage, along with supporting data such as x-rays, bone scans, and MRIs will be presented, as well as a suggested treatment plan for the chronic resistant cases.
Desarrollo de una cultura de calidad

En las ultimas decadas del siglo XX, el concepto de calidad surge con gran impacto en organizaciones del ambito empresarial e industrial. Conforme avanzaron los anos y estas iniciativas se fueron difundiendo y popularizando, a la fecha han llegado a casi todos los sectores economicos; asi por ejemplo, este nuevo paradigma o cultura la encontramos en servicios financieros, educativos, politicos, de salud, organizacionales, administrativos, entre otros. Desde esta mirada, la lectura de esta obra nos permite reflexionar acerca de lo importante que es, como individuos y como sociedad, ser mas competentes en todos los ambitos de la vida. Ser una persona competente adquiere diferentes significados, la competencia humana general es el producto del dominio de conceptos, destrezas y actitudes; ser competente significa que la persona tiene el conocimiento declarativo; es decir, sabe lo que hace, por que lo hace y conoce el objeto sobre el que actua. Ser competente tambien implica, tener la capacidad de ejecucion, es decir el conocimiento procesal o las destrezas intelectuales y psicomotoras para en efecto llevar a cabo la ejecucion sobre el objeto.
Is "frequency distribution" enough to detect tremor in PD patients using a wrist worn accelerometer?

This paper presents two approaches on detecting tremor in patients with Parkinson's Disease by means of a wrist-worn accelerometer. Both approaches are evaluated in terms of specificity and sensitivity as well as their applicability for a real-time implementation. One approach is solely based on the frequency distribution of a windowed time series, while the second approach utilizes commonly employed features found in the literature (e.g. FFT, entropy, peak frequency, correlation). The two algorithms detect tremor at rest in windowed time series. The effects of varying window lengths and detection thresholds are studied. The results indicate that an SVM with a linear kernel, in combination with the frequency distribution, may already be enough to accurately and reliably detect tremor in windowed time series. The approach, after being trained with a first dataset of signals obtained from 12 patients, achieved a sensitivity of 88.4% and specificity of 89.4% in a second dataset from 64 PD patients.
Relative benefit of a stage of change approach for the prevention of musculoskeletal pain and discomfort: a cluster randomised trial

Objectives To examine the benefit of a psychological Stage of Change (SOC) approach, relative to standard ergonomics advice, for the prevention of work-related musculoskeletal pain and discomfort (MSPD). Methods A cluster randomised trial was conducted in South Australia across a broad range of workplaces. Repeated face-to-face interviews were conducted onsite to assess MSPD, safety climate, job satisfaction and other factors. Changes in MSPD across intervention groups and time were investigated using Generalised Estimating Equation (GEE) methods. Results 25 workgroups (involving 242 workers) were randomly allocated to either a standard intervention or an intervention tailored according to SOC. The prevalence of MSPD increased for both groups, but was only significant for the standard group, in respect of lower back MSPD. Workers receiving tailored interventions were 60% less likely to experience lower back MSPD. After adjusting for age, gender and job satisfaction, it was found that company safety climate and length of employment were significantly correlated to the time-intervention effect. There was no correlation with workload. Conclusions Compared with standard ergonomics advice to management, there was evidence of a benefit of stage-matched intervention for MSPD prevention, particularly for low back pain. Organisational safety climate should be taken into account when planning prevention programmes.
Enhanced indoor propagation model for WLAN system

Radio propagation in the local networks (IEEE 802.11g) is the object of intensive researches. This paper provides an indoor channel propagation model for wireless local access network (WLAN). The considered model is built based on various power measurements of the channel signal level at different positions in the covered area. The collected data is associated to the moment and the tridimensional position. The computation enables the establishment of a new WLAN propagation model which is more accurate compared to the existing one found in the literature. The simulations results highlight the efficiency of the considered model.
An efficient FPGA-based implementation of Pollard's (ρ - 1) factorization algorithm

Due to the widespread use of public key cryptosystems whose security depends on the presumed difficulty of the factorization problem, the algorithms for finding the prime factors of large composite numbers are becoming extremely important. In recent years the limits of the best integer factorization algorithms have been extended greatly, due in part to Moore's law and in part to algorithmic improvements. Furthermore, new silicon devices, such as FPGAs, give us the advantage of custom hardware architectures for minimizing execution time for such difficult computations. This paper demonstrates a very efficient FPGA-based design executing Pollard's (ρ - 1) factorization algorithm. The proposed device offers a speedup from 20 to 231 when compared to the software implementation of the same algorithm in a state-of-the-art CPU.
Production of Health in Chinese households : Children ’ s overweight and obesity

Modernization and subsequent changes in lifestyle have caused a dramatic increase in prevalence of overweight and obesity in China (WHO, 2000; Wu, 2006). Since obesity is one of the main forces driving Noncommunicable Diseases (NCDs), increases in prevalence of obesity in children lead to higher incidence of NCDs and reduction in health human capital. I use the China Health and Nutrition Survey (CHNS) to carry out structural estimation of health production function for children in China. Results suggest that calorie intake is the most important input in the production of excessive weight with an impact on weight three times larger than sedentary activities and six times larger than physical activities. Calorie intake also has a more than proportional effect on unhealthy extra weight. These results suggest that public health policies targeting obesity in children must focus on reducing excessive calorie intake.
Design of ERMC and RMM, the Base of the Nb3Sn 16 T Magnet Development at CERN

High-field superconducting accelerator magnets are a key technology of the future circular collider. In order to master the technical challenges and achieve the performance targets, CERN has launched a technology development program. The first step of the program is to explore the Nb3Sn performance limits at 18 T field level and high stress, simplifying to the maximum the coil geometry. The first magnet to be built, the enhanced racetrack model coil (ERMC), aims at a mid-plane field of 16 T with 10% margin on the load line at 4.2 K. The ERMC is composed of two flat racetrack coils with no bore. To further develop the block-coil geometry, a second magnet, the racetrack model magnet (RMM), will be composed of two ERMC coils and a middle coil with a 50-mm closed cavity, addressing the issue of the design of an inner support to compensate for the preload forces. The RMM aims at a central field of 16 T in a 50-mm cavity, with 10% margin at 4.2 K. The next step is to develop a more compact and cost-effective design using two cable sizes, and therefore two different current densities. The coils will be assembled in a shell-based support structure using bladders and keys, which allows a precise control of the stress with minimal spring back and conductor overstress. This paper describes the magnetic and mechanical design of the ERMC and the RMM.
ONCE and ONCE+: Counting the Frequency of Time-constrained Serial Episodes in a Streaming Sequence

As a representative sequential pattern mining problem, counting the frequency of serial episodes from a streaming sequence has drawn continuous attention in academia due to its wide application in practice, e.g., telecommunication alarms, stock market, transaction logs, bioinformatics, etc. Although a number of serial episodes mining algorithms have been developed recently, most of them are neither stream-oriented, as they require multi-pass of dataset, nor time-aware, as they fail to take into account the time constraint of serial episodes. In this paper, we propose two novel one-pass algorithms, ONCE and ONCE+, each of which can respectively compute two popular frequencies of given episodes satisfying predefined time-constraint as signals in a stream arrives one-after-another. ONCE is only used for non-overlapped frequency where the occurrences of a serial episode in sequence are not intersected. ONCE+ is designed for the distinct frequency where the occurrences of a serial episode do not share any event. Theoretical study proves that our algorithm can correctly mine the frequency of target time constraint serial episodes in a given stream. Experimental study over both real-world and synthetic datasets demonstrates that the proposed algorithm can work, with little time and space, in signal-intensive streams where millions of signals arrive within a single second. Moreover, the algorithm has been applied in a real stream processing system, where the efficacy and efficiency of this work is tested in practical applications.
Cutaneous presentation of progressive disseminated histoplasmosis nine years after renal transplantation

Initial presentation of invasive fungal infections such as histoplasmosis can include non‐specific clinical manifestations, especially in immunocompromised patients. A high index of suspicion is required to identify atypical manifestations of these diseases, which carry a high risk of mortality, if the diagnosis is delayed or missed. We describe a case of a kidney transplant recipient with cutaneous lesions as initial manifestation of progressive disseminated histoplasmosis where a skin biopsy was crucial to an early diagnosis.
Learning Logic Program Representation from Delayed Interpretation Transition Using Recurrent Neural Networks

Having a method to understand the interactions and delayed influences between components of dynamical systems can provide useful applications to biological and other dynamical systems. In this paper, we present a method relying on Recurrent Neural Networks (RNN) that can learn to distinguish the nature of different systems. This method utilizes Long ShortTerm Memory (LSTM) to extract and encode features from the input sequence of time series data. We also show that the produced high dimensional encoding can be used to distinguish time series that originate from different dynamical systems.
Institutional Interventions in Addressing Labour Scarcity – A Study on Labour Bank Initiatives in Thrissur District of Kerala

The study has highlighted an institutional intervention in the form of Labour Banks to address the scarcity of farm labourers in Kerala. The study has estimated the impact of Labour Banks on farm productivity, farm income, employment and standard of living of labourers. The study has used difference-in-difference estimation, partial budgeting technique and ANCOVA model for analysis. The Labour Bank memberlabourers have depicted improvement in their standard of living, and their wage rate was higher by 21 per cent compared to that of non-members. The farmers who used Labour Bank service could achieve a rise of 0.92 t/ha in paddy productivity, and a profit of ̀ 11448/ha. The study has suggested replication of such models in other areas of the country also.
The Ideas Lab Concept, Assembling the Tree of Life, and AVAToL

In August 2011, a week-long NSF-sponsored workshop focusing on the Tree of Life (ToL) took place in Lake Placid, New York. This workshop, called AVAToL (Assembling Visualizing, and Analyzing the Tree of Life), was the first application of NSF’s Ideas Lab concept to systematics. In this article we outline the history and motivation for the Ideas Lab approach and its application to the ToL, explain the nuts and bolts of the Ideas Lab process and look to the potential contributions of AVAToL funded projects to help enable the future of ToL and more broadly, comparative biological research.
