Groove in drum patterns as a function of both rhythmic properties and listeners’ attitudes

Music psychology defines groove as humans’ pleasureable urge to move their body in synchrony with music. Past research has found that rhythmic syncopation, event density, beat salience, and rhythmic variability are positively associated with groove. This exploratory study investigates the groove effect of 248 reconstructed drum patterns from different popular music styles (pop, rock, funk, heavy metal, rock’n’roll, hip hop, soul, R&B). It aims at identifying factors that might be relevant for groove and worth investigating in a controlled setting in the future. Drum patterns of eight bars duration, chosen from 248 popular music tracks, have been transcribed and audio reconstructions have been created on the basis of sound samples. During an online listening experiment, 665 participants rated the reconstructions a total of 8,329 times using a groove questionnaire. Results show that, among 15 tested variables, syncopation (R2 = 0.010) and event density (R2 = 0.011) were positively associated with the groove ratings. These effects were stronger in participants who were music professionals, compared to amateur musicians or mere listeners. A categorisation of the stimuli according to structural aspects was also associated with groove (R2 = 0.018). Beat salience, residual microtiming and rhythmic variability showed no effect on the groove ratings. Participants’ familiarity with a drum pattern had a positive influence on the groove ratings (η2 = 0.051). The largest isolated effect was measured for participants’ style bias (R2 = 0.123): groove ratings tended to be high if participants had the impression that the drum pattern belonged to a style they liked. Combined, the effects of style bias and familiarity (R2 = 0.152) exceeded the other effects as predictors for groove by a wide margin. We conclude that listeners’ taste, musical biographies and expertise have a strong effect on their groove experience. This motivates groove research not to focus on the music alone, but to take the listeners into account as well.
Overview of speciation chemistry of arsenic

Studies on the speciation of arsenic in environmental and biological samples are a subject of current interest. Because of the low level of arsenic species in real samples, many problems related with its speciation remain unresolved: species instability during sampling, storage and sample treatment, incomplete recovery of all species, matrix interferences, lack of appropriate certified reference materials and of sensitive analytical methods, etc. The continued development of new analytical procedures to solve some of these problems claim for an up-to-date knowledge of the recent publications. The analytical figures of merit, specially detection limits are given for most of the methods in order to afford comparison and judge possible applicability. These studies, which have been approached in many different ways, would lead to knowledge that is determinant in the understanding of the cycle of this element in the environment and of its physiological and toxicological behaviour in the living organisms.
Modulation of seminal plasma content in extended semen improves the quality attributes of ram spermatozoa following liquid preservation at 3–5°C

Seminal plasma (SP) is known to induce motility and capacitation in spermatozoa curtailing their lifespan when preserved. Hence, this study was conducted to examine the effects of removal of SP from sperm surface prior to liquid preservation either by high dilution (1/15) or by washing and the poststorage treatment with SP (15% and 25%, v/v) on the quality attributes of liquid-preserved ram semen. Over the period of storage, the rapid motility (66.0% and 71.1% vs. 58.3%), straightness (87.1% and 82.1% vs. 79.4%), average path velocity (152.3 and 152.0 µm/s vs. 133.3 µm/s) and the straight-line velocity (131.3 and 127.8 µm/s vs. 108.5 µm/s) were significantly (p < 0.05) higher in both the high-dilution and wash groups as compared to the control (1/3 dilution). The functional membrane integrity (82.3% vs. 77.2%) and noncapacitated sperm count (65.0% vs. 58.7%) were also significantly (p < 0.05) higher in the high-dilution and wash groups, respectively, as compared to the control. The poststorage treatment of sperm with SP significantly (p < 0.05) increased the functional membrane integrity (70.1% vs. 53.8%) and most of the motility attributes as compared to the control (without SP). In conclusion, both the removal of SP prior to liquid preservation and poststorage treatment with SP significantly improved the quality attributes of ram spermatozoa.
Two critical positions in zinc finger domains are heavily mutated in three human cancer types

A major goal of cancer genomics is to identify somatic mutations that play a role in tumor initiation or progression. Somatic mutations within transcription factors are of particular interest, as gene expression dysregulation is widespread in cancers. The substantial gene expression variation evident across tumors suggests that numerous regulatory factors are likely to be involved and that somatic mutations within them may not occur at high frequencies across patient cohorts, thereby complicating efforts to uncover which ones are cancer-relevant. Here we analyze somatic mutations within the largest family of human transcription factors, namely those that bind DNA via Cys2His2 zinc finger domains. Specifically, to hone in on important mutations within these genes, we aggregated somatic mutations across all of them by their positions within Cys2His2 zinc finger domains. Remarkably, we found that for three classes of cancers profiled by The Cancer Genome Atlas (TCGA)—Uterine Corpus Endometrial Carcinoma, Colon and Rectal Adenocarcinomas, and Skin Cutaneous Melanoma—two specific, functionally important positions within zinc finger domains are mutated significantly more often than expected by chance, with alterations in 18%, 10% and 43% of tumors, respectively. Numerous zinc finger genes are affected, with those containing Krüppel-associated box (KRAB) repressor domains preferentially targeted by these mutations. Further, the genes with these mutations also have high overall missense mutation rates, are expressed at levels comparable to those of known cancer genes, and together have biological process annotations that are consistent with roles in cancers. Altogether, we introduce evidence broadly implicating mutations within a diverse set of zinc finger proteins as relevant for cancer, and propose that they contribute to the widespread transcriptional dysregulation observed in cancer cells.
Segmentation issues in a horizontal buried cable considering frequency dependent soil models

This study shows the effect of soil modeling in a electromagnetic analysis regarding a current injection in a buried cable, as a grounding element subject to electric transients. Two frequency-dependent soil models are chosen, along with a constant parameters model, showing divergent results in higher frequencies. Also, the numerical simulation regarding the cable subdivision are addressed, exposing the importance in calculations of ground potentials and electric fields nearby. The results concludes the importance of further knowledge of the soils properties at high frequencies.
Proposal of an Extended Taxonomy of Serious Games for Health Rehabilitation.

OBJECTIVE Serious Games is a field of research that has evolved substantially with valuable contributions to many application domains and areas. Patients often consider traditional rehabilitation approaches to be repetitive and boring, making it difficult for them to maintain their ongoing interest and assure the completion of the treatment program. Since the publication of our first taxonomy of Serious Games for Health Rehabilitation (SGHR), many studies have been published with game prototypes in this area. Based on literature review, our goal is to propose an updated taxonomy taking into account the works, updates, and innovations in game criteria that have been researched since our first publication in 2010. In addition, we aim to present the validation mechanism used for the proposed extended taxonomy. MATERIALS AND METHODS Based on a literature review in the area and on the analysis of the contributions made by other researchers, we propose an extended taxonomy for SGHR. For validating the taxonomy proposal, a questionnaire was designed to use on a survey among experts in the area. RESULTS An extended taxonomy for SGHR was proposed. As we have identified that, in general, and besides the mechanisms associated with the adoption of a given taxonomy, there were no reported validation mechanisms for the proposals, we designed a mechanism to validate our proposal. The mechanism uses a questionnaire addressed to a sample of researchers and professionals with experience and expertise in domains of knowledge interrelated with SGHR, such as Computer Graphics, Game Design, Interaction Design, Computer Programming, and Health Rehabilitation. CONCLUSION The extended taxonomy proposal for health rehabilitation serious games provides the research community with a tool to fully characterize serious games. The mechanism designed for validating the taxonomy proposal is another contribution of this work.

Systemic Inflammatory Response and Atherosclerosis: The Paradigm of Chronic Inflammatory Rheumatic Diseases

Patients with Chronic Inflammatory Rheumatic diseases (CIRD) are at increased risk of cardiovascular disease (CVD), ascribed not only to classical risk factors, but also to the presence of chronic systemic inflammatory response. Αtherosclerosis, the cornerstone of CVD, is known to be accelerated in CIRD; rheumatoid arthritis promotes atheromatosis and associates with preclinical atherosclerosis equivalent to Diabetes Mellitus, which also seems to apply for systemic lupus erythematosus. Data on ankylosing spondylitis and psoriatic arthritis, albeit more limited, also support an increased CV risk in these patients. The association between inflammation and atherosclerosis, has been thoroughly investigated in the last three decades and the role of inflammation in the pathogenesis and progression of atherogenesis has been well established. Endothelial dysfunction, oxidative stress in vascular endothelial cells and macrophage accumulation, toll-like receptor signaling, NLPR-3 formation and subsequent pro-inflammatory cytokine production, such as TNFa, IL-1β, IL-6, and TNF-like cytokine 1A, are few of the mechanisms implicated in the atherogenic process. Moreover, there is evidence that anti-inflammatory biologic drugs, such as anti-TNF and anti-IL1β agents, can decelerate the atherogenic process, thus setting new therapeutic targets for early and effective disease control and suppression of inflammation, in addition to aggressive management of classical CV risk factors.
Cloning and expression of bacteriocins of Pediococcus spp.: A review

Natural food biopreservatives have alwaysâ€™s remained the preference of health consciousconsumers. This necessity has led to the studies exploring better alternativeswhich are more acceptable, economical and safer than chemical preservatives. Bacteriocinsare one of such compounds produced by lactic acid bacteria which offera great potential to contribute in food, health and pharmaceutical industry. Presentreview focuses the complete biochemical, functional and molecular genetic characterizationof bacteriocins produced by Pediococcus spp. A great deal of diverseheterologous expression systems have been exploited for cloning, expression andpurification of pediocins at laboratory scale but data is lacking for industrial processes.Thus, there is an urgent need to design low cost, industrially viable and continuoussystem in order to exploit these natural bioactive compounds in food andpharmaceutical industry
The morphology of Idiocranium russeli (amphibia: Gymnophiona), with comments on miniaturization through heterochrony

Idiocranium russeli is among the smallest species of caecilians. The morphology of the skull (e.g., small, widely spaced dermal elements, retention of cartilaginous remnants) and of the posterior vertebrae (incomplete development, retention of a postvertebral notochord) indicate that heterochrony, or change in timing of development, has resulted in the miniaturization of the species. The pattern is apparently a progenetic one, characterized by early offset of development (see Alberch et al., 1979). Other unique features of osteology (e.g., extensive sphenethmoid development) correlate with the burrowing habit of the species and may have arisen to compensate for progenetic effects. Several features of the myology, neurology, and visceral morphology are correlated with miniaturization as well. Reproductive maturity occurs at approximately 75 mm total length; gonads are proportionately small, but other aspects of reproductive morphology are typical of direct‐developing caecilians.
Using 3D convolutional neural network in surveillance videos for recognizing human actions

: Human action recognition is a very important component of visual surveillance systems. The demand for automatic surveillance systems play a crucial role in the circumstances where continuous patrolling by human guards are not possible. The analysis in surveillance scenarios often requires the detection of certain specific human actions. The automated recognition of human actions in detecting certain human actions are considered here. The main aim is to develop a novel 3D Convolutional Neural Network (CNN) model for human action recognition in realistic environment. The features are extracted from both the spatial and the temporal dimensions by performing 3D convolutions, by which, capturing the motion information encoded in multiple adjacent frames. The evolved model generates multiple information from the input frames, and the information from all the channels are combined and that is to be the final feature. The developed model automatically tends to recognize specific human actions which needs attention in the real world environment like in pathways or in corridors of any organization. This proposed work is well suitable for the situations like where continuous patrolling of humans are not possible, to prevent certain human actions which are not allowed inside the organisation premises.
All the Things You Are: Accessing An Enriched Musicological Prosopography Through JazzCats

JazzCats (Jazz Collection of Aggregated Triples) is a prototype project which uses Linked Open Data (LOD) to support musicological, historical, and prosopographical analyses. It has increased access to (and the openness of) data published online through a twofold process: firstly, information hitherto unavailable to users has been shared and incorporated into the project, and secondly, data previously locked in non-Open types (e.g. PDF) has been published in a machine-readable format, increasing discoverability in the context of the wider Web. Connections between datasets that could only be identified through a human user engaging separately with each existing project have now been made explicit, and the resulting aggregated data is queryable from a single userinterface (UI). Three projects contribute to JazzCats: a social network connecting musicians through various types of relationships is provided by LinkedJazz (Pattuelli, 2016); details of solos within performances (including pitch, key, and chord changes) are available from WJazzD (Pfleiderer et al., 2016); and Body&Soul (Bowen, 2013) is a discography of over 200 recordings. These complementary data contain instance-level overlaps for recordings and musicians. Bringing these resources together has enabled a new type of research question, possible only through using criteria from one dataset to inform and hone results from another.
Web Science: Now More Than Ever

The Web has transformed our lives, and a cursory review of recent headlines shows both our dreams and nightmares writ large as a result. Is it possible to retain the benefits through algorithms and apps for romance, books, music, and fitness, without suffering the devastation wrought by the hacking of health records, elections, and bank accounts? This special issue explores the many facets of Web Science, the study of the Web’s impact on our society and technology, and how we can use it to achieve our dreams without living our nightmares.
Soft Biomimetic Fish Robot Made of Dielectric Elastomer Actuators

Abstract This article presents the design, fabrication, and characterization of a soft biomimetic robotic fish based on dielectric elastomer actuators (DEAs) that swims by body and/or caudal fin (BCF) propulsion. BCF is a promising locomotion mechanism that potentially offers swimming at higher speeds and acceleration rates, and efficient locomotion. The robot consists of laminated silicone layers wherein two DEAs are used in an antagonistic configuration, generating undulating fish-like motion. The design of the robot is guided by a mathematical model based on the Euler–Bernoulli beam theory and takes account of the nonuniform geometry of the robot and of the hydrodynamic effect of water. The modeling results were compared with the experimental results obtained from the fish robot with a total length of 150 mm, a thickness of 0.75 mm, and weight of 4.4 g. We observed that the frequency peaks in the measured thrust force produced by the robot are similar to the natural frequencies computed by the model. The peak swimming speed of the robot was 37.2 mm/s (0.25 body length/s) at 0.75 Hz. We also observed that the modal shape of the robot at this frequency corresponds to the first natural mode. The swimming of the robot resembles real fish and displays a Strouhal number very close to those of living fish. These results suggest the high potential of DEA-based underwater robots relying on BCF propulsion, and applicability of our design and fabrication methods.
Analysis of insertion of wind power plants in the process of fluent restoration of the Brazilian interconnected power system

The definition of a strategy for the restoration of an electric system should restoring the largest amount of load as soon as possible in a gradual and safe way until the total restoration of the system. In this context, due to the relevant and continuous contribution of the wind power plants to the load of the Brazilian Interconnected Power System (BIPS), mainly of the Northeast Subsystem, this work study the possibility of insertion of wind power plants in the hydroelectric plants corridors with black-start capacity, to increase load and minimizing interruption time. For this evaluation, ANATEM analyzes are carried out, in accordance with the Network Procedures, being considered in the modeling the wind power input of the Paranatama substation which has a connection with the Garanhus II substation, belonging to the East of Luiz Gonzaga Area, located in the Northeast region.
A randomized controlled trial of fixed‐ versus mobile‐bearing total knee arthroplasty: A FOLLOW‐UP AT A MEAN OF TEN YEARS

Aims It has been suggested that mobile‐bearing total knee arthroplasty (TKA) might lead to better outcomes by accommodating some femorotibial rotational mismatch, thereby reducing contact stresses and polyethylene wear. The aim of this study was to determine whether there is a difference between fixed‐ and mobile‐bearing versions of a contemporary TKA with respect to durability, range of movement (ROM) and function, ten years postoperatively. Patients and Methods A total of 240 patients who were enrolled in this randomized controlled trial (RCT) underwent a primary cemented TKA with one of three tibial components (all‐polyethylene fixed‐bearing, modular metal‐backed fixed‐bearing and mobile‐bearing). Patients were reviewed at a median follow‐up of ten years (IQR 9.2 to 10.4). Results There was no difference in durability, as measured by survivorship free of revision for any reason, nor in mean maximal ROM at ten years (p = 0.8). There was also no difference in function, as measured by Knee Society (KS) function scores (p = 0.63) or the prevalence of patellar tilt (p = 0.12). Conclusion In this clinical RCT, the mobile‐bearing design of TKA was found to be reliable and durable, but did not provide better maximum knee flexion, function or durability ten years postoperatively compared with a posterior‐stabilized, fixed‐bearing design incorporating either an all‐polyethylene or a modular‐metal‐backed tibial component.

It additionally considers potential research and treatment priorities in the face of widespread cannabis legalization.
An introduction to the architecture of the Intel iAPX 432

The paper describes salient architectural features of the Intel iAPX 432, a recent innovative microprocessor design. It is intended as a companion to a recently published paper (Witten, 1981) which surveys the architectures of the new generation of 16-bit microprocessors, but which was written prior to the announcement of the iAPX 432. The novelty of the new processor lies chiefly in its sophisticated segmentation structure and the design of its instruction set; these are covered in a tutorial fashion and related to earlier developments in computer architecture
