In Search of the Fastest Concurrent Union-Find Algorithm

Union-Find (or Disjoint-Set Union) is one of the fundamental problems in computer science; it has been well-studied from both theoretical and practical perspectives in the sequential case. Recently, there has been mounting interest in analyzing this problem in the concurrent scenario, and several asymptotically-efficient algorithms have been proposed. Yet, to date, there is very little known about the practical performance of concurrent Union-Find. This work addresses this gap. We evaluate and analyze the performance of several concurrent Union-Find algorithms and optimization strategies across a wide range of platforms (Intel, AMD, and ARM) and workloads (social, random, and road networks, as well as integrations into more complex algorithms). We first observe that, due to the limited computational cost, the number of induced cache misses is the critical determining factor for the performance of existing algorithms. We introduce new techniques to reduce this cost by storing node priorities implicitly and by using plain reads and writes in a way that does not affect the correctness of the algorithms. Finally, we show that Union-Find implementations are an interesting application for Transactional Memory (TM): one of the fastest algorithm variants we discovered is a sequential one that uses coarse-grained locking with the lock elision optimization to reduce synchronization cost and increase scalability.
Lie algebras arising from Nichols algebras of diagonal type

Let ${\mathcal B}_{\mathfrak{q}}$ be a finite-dimensional Nichols algebra of diagonal type with braiding matrix $\mathfrak{q}$, let $\mathcal{L}_{\mathfrak{q}}$ be the corresponding Lusztig algebra as in arXiv:1501.0451(8) and let $\operatorname{Fr}_{\mathfrak{q}}: \mathcal{L}_{\mathfrak{q}} \to U(\mathfrak{n}^{\mathfrak{q}})$ be the corresponding quantum Frobenius map as in arXiv:1603.0938(7). We prove that the finite-dimensional Lie algebra $\mathfrak{n}^{\mathfrak{q}}$ is either 0 or else the positive part of a semisimple Lie algebra $\mathfrak{g}^{\mathfrak{q}}$ which is determined for each $\mathfrak{q}$ in the list of arXiv:arch-ive/0605795.
A Turing test for crowds

The accuracy and believability of crowd simulations underpins computational studies of human collective behaviour, with implications for urban design, policing, security and many other areas. Accuracy concerns the closeness of the fit between a simulation and observed data, and believability concerns the human perception of plausibility. In this paper, we address both issues via a so-called ‘Turing test’ for crowds, using movies generated from both accurate simulations and observations of real crowds. The fundamental question we ask is ‘Can human observers distinguish between real and simulated crowds? ’ In two studies with student volunteers (n = 384 and n = 156), we find that non-specialist individuals are able to reliably distinguish between real and simulated crowds when they are presented side-by-side, but they are unable to accurately classify them. Classification performance improves slightly when crowds are presented individually, but not enough to out-perform random guessing. We find that untrained individuals have an idealized view of human crowd behaviour which is inconsistent with observations of real crowds. Our results suggest a possible framework for establishing a minimal set of collective behaviours that should be integrated into the next generation of crowd simulation models.
EPIDEMIOLOGY AND SYMPTOMATOLOGY OF EXUDATIVE AND TRANSUDATIVE TYPE OF ASCITES IN HOSPITALIZED PATIENTS

Ascites is the pathological accumulation of fluid in the peritoneal cavity, associated with many clinical symptoms and had various causes. The descriptive observational study was carried out in admitted patients of Civil Hospital Karachi from April 2011 to June 2011. This study was conducted to determine the frequency of major causes and important clinical findings in Ascitic patients. All the admitted patients in medicine wards with the presentation of Ascites were included in this study. The data was collected on a Performa having questions regarding basic patient information, laboratory reports, result of clinical examination and clinical findings. Verbal informed consent was taken and confidentiality was maintained. A total of eighty eight (88) ascitic patients of mean age 50.75±15.845, were evaluated during three months. It was slightly more common in females as compared to males. Most common fluid present in the peritoneal cavity was of transudative type as compare to exudative fluid. Common causes of Ascites were Hepatitis C (53.4%), Hepatitis B (15.9%), chronic renal failure (4.5%) and T.B peritonitis (2.3%). Major co-morbid symptoms of ascitic patients were abdominal pain (52.3%), fever (47.7) and altered level of consciousness (36.4%). Data entry and analysis were done through SPSS 19. A large number of cases of Ascites were due to Hepatitis C and Hepatitis B. For the management of these diseases media and NGOs should come forward and create the awareness regarding these deadly problems.
OP-NDTP180042 1..10

Background. Aortic stiffness is one of the earliest signs of cardiovascular disease (CVD) in patients with chronic kidney disease and an independent predictor of mortality. It is thought to drive left ventricular (LV) remodelling, an established biomarker for mortality. The relationship between direct and indirect measures of aortic stiffness and LV remodelling is not defined in dialysis patients, nor are the reproducibility of methods used to assess aortic stiffness using cardiac magnetic resonance (CMR) imaging. Methods. Using 3T CMR, we report the results of (i) the interstudy, interobserver and intra-observer reproducibility of ascending aortic distensibility (AAD), descending aortic distensibility (DAD) and aortic pulse wave velocity (aPWV) in 10 haemodialysis (HD) patients and (ii) the relationship between AAD, DAD and aPWV and LV mass index (LVMi) and LV remodelling in 70 HD patients. Results. Interand intra-observer variability of AAD, DAD and aPWV were excellent [intraclass correlation (ICC) >0.9 for all]. Interstudy reproducibility of AAD was excellent {ICC 0.94 [95% confidence interval (CI) 0.78–0.99]}, but poor for DAD and aPWV [ICC 0.51 ( 0.13–0.85) and 0.51 ( 0.31–0.89)]. AAD, DAD and aPWV associated with LVMi on univariate analysis (b1⁄4 0.244, P1⁄40.04; b1⁄4 0.315, P<0.001 and b1⁄40.242, P1⁄40.04, respectively). Only systolic blood pressure, serum phosphate and a history of CVD remained independent determinants of LVMi on multivariable linear regression. Received: 12.4. 2018.

Radiative Properties of Magnetically Arrested Disks

Magnetically arrested disks (MADs) appear when accretion flows are supplied with a sufficient amount of magnetic flux. In this work, we use results of magnetohydrodynamic simulations to set the configuration of the magnetic field and investigate the dynamics and radiative properties of the resulting accretion flow (i.e., without that of the jet) of MADs. The method developed here is applied to both the MAD and the standard and normal evolution (SANE) accretion flow with or without large-scale magnetic fields. For the radiative processes, we include synchrotron, bremsstrahlung, and Compton scattering. We find that, in general, accretion flows of MADs have similar spectra to those of the SANE, which complicates the task of distinguishing MADs from SANEs. At the same accretion rates, MADs are systematically brighter than SANEs. However, the critical accretion rate above which the hot solution ceases to exist is lower in MADs. Consequently, the maximum luminosity an MAD can reach is comparable to but slightly lower than that of SANE, and the dependence on the magnetic flux is weak. We then discuss the implications of our results for active galactic nuclei and accreting black hole binaries.
manufacturinG inDustry as a case stuDy

There is currently an important general debate in South Africa (among employer organisations, labour unions, politicians etc.) on the size and fairness of perceived employee-remuneration gaps among the different employment levels in organisations. Labour unions, in particular, are of the opinion that these remuneration gaps are expanding and that the situation constitutes a major threat to job creation and the fair distribution of income in the workplace and the economy as a whole. Employer organisations, however, argue that employee-remuneration gaps are, in the main, the result of the shortages of higher-skilled employees in the workplace and differences in labourproductivity levels between the different employee segments.
ASCAI: Adaptive Sampling for acquiring Compact AI

This paper introduces ASCAI, a novel adaptive sampling methodology that can learn how to effectively compress Deep Neural Networks (DNNs) for accelerated inference on resource-constrained platforms. Modern DNN compression techniques comprise various hyperparameters that require per-layer customization to ensure high accuracy. Choosing such hyperparameters is cumbersome as the pertinent search space grows exponentially with the number of model layers. To effectively traverse this large space, we devise an intelligent sampling mechanism that adapts the sampling strategy using customized operations inspired by genetic algorithms. As a special case, we consider the space of model compression as a vector space. The adaptively selected samples enable ASCAI to automatically learn how to tune per-layer compression hyperparameters to optimize the accuracy/model-size trade-off. Our extensive evaluations show that ASCAI outperforms rule-based and reinforcement learning methods in terms of compression rate and/or accuracy
Distribution of fingerprint patterns among first year medical students in Al-Ameen Medical College, Bijapur

Introduction: Fingerprint evidence is undoubtedly the most reliable and acceptable evidence as one of the most mature biometric technologies and are considered to be legitimate proofs of evidence in courts of law for human identification all over the world as they are constant and individualistic Aim: The present study was done to see the pattern of fingerprints among first year medical students. Methods: Study was carried out among 120 first year medical students (60 male & 60 female) belonging to the age group 17-21 years of AlAmeen Medical College, Bijapur, Karnataka, during the period of 2016-17. Fingerprints of the fingertips were taken using the ink method. Distribution of fingerprint patterns were studied in both hands among males and females and are compared. Results: As finger prints are unique, whorls are the most commonly occurring fingerprint pattern while arches are the least common. Frequency of whorls is comparatively higher and that of loops lower. Conclusion: Different patterns of fingerprints are present in different digits in both males and females.
Corporate governance rating and its impact on firm level performance and valuation

Purpose This paper examines the firm specific characteristics that drive companies in India to superior governance and sustainability performance and reporting as proxied by their presence in the S&P ESG India index. It further seeks to investigate whether the corporate financial performance is impacted by corporate governance & sustainability performance and reporting. Design/methodology/approach This study proposes to use the rating of companies by the S&P ESG India index and company related performance data as available from Prowess (CMIE). The analysis will require the use of Pearson’s correlations and regression analysis model to understand whether Indian investors value governance and sustainability reporting. Findings These findings have important implications not only for the investors, the corporations, and the managers but also for regulatory authorities, governments and various bodies around the world which are trying to create awareness about better governance and sustainability, particularly in emerging economies like India. Research limitations/implications The sample size of firms taken could have been more to include firms across all sectors. A cross country analysis would have helped us to understand whether similar results emerge in their context. Practical implications In Indian context, it would be interesting to understand how the mandatory Corporate Governance and Business Responsibility reports submitted by companies’ impact their stakeholder holder perception. Originality/value This study is unique in analyzing whether governance and sustainability rating of Indian corporate translate into stakeholder value creation.
AD-A 240 470 PRELIMINARY

Two experiments were conducted to assess the relative benefits of redundantly and non-redundantly combining the stimulus dimensions of saturation and brightness with hue in symbolic visual displays. Previous research has indicated that both saturation and brightness may be related to hue in such a way that a facilitation in search performance might be realized if these dimensions were combined in a tactical display symbology. Subjects completed extensive visual search paradigms on CRT based tactical displays. In experiment 1, three hues (red, blue, and yellow) and three saturation levels (most, middle, and least saturated) were varied, while symbol shape was held constant. The stimulus combinations of hue and saturation were combined in redundant and non-redundant conditions, which enabled the quantification of the integrality and separability of the hue and saturation dimensions. The analysis of the search reaction times and the number of correct responses revealed a significant interference effect when the stimulus dimensions were combined in a non-redundant manner and the subjects were forced to search for targets of a specific saturation level. Compared to simple one dimensional search conditions, search performance was not improved when saturation was redundantly coded with hue, thus an integral facilitation effect was absent from the data. Based on the results of experiment 1, the use of different saturation levels within a hue may be ill-advised for applications in military tactical displays and civilian air traffic control. The presence of interference without facilitation argues for the exclusion of saturation as a separate or redundant coding dimension in tactical displays. In experiment 2, the three hues were varied with three stimulus brightness levels. The results were similar to those of experiment one, except that the interference effect in the non-redundant coding condition was due primarily to the medium brightness levels. If restricted to two levels, brightness might be a useful redundant code. Overall, the results lend support to algorithms that work to maximize color differences (in the CIE space) for use in visual displays. Ancession For NTIS GRA&I DTIC TAF El
The development of submucosal injection of platelet rich plasma for accelerating orthodontic tooth movement and preserving pressure side alveolar bone

Although the surgical-assisted accelerated orthodontic tooth movement has been proved to be the most effective one currently, its disadvantages are it is a bone surgery, and it causes loss of alveolar bone that undermines the periodontal support of the target teeth. The submucosal injection of platelet rich plasma (PRP) is a technique developed for accelerating orthodontic tooth movement by simulating the effects of bone insult without surgery and loss of alveolar bone. We have revealed clinically that submucosal injection of PRP accelerated the mandibular or maxillary alignment 1.7 folds faster in average, and the acceleration was dose-dependent when the PRP fold (platelet count in PRP/platelet count in blood) was <12.5. The optimal PRP fold for a more than 2-fold acceleration of orthodontic alignment ranged from 9.5 to 12.5 folds. On the other hand, the injection of PRP on the pressure side of en masse anterior retraction decreased 71–77% of alveolar bone loss, and this was dose-dependent. The pressure side of en masse anterior retraction had no alveolar bone loss when the PRP fold was higher than 11.0. In conclusion, the optimal PRP fold for the best performance in acceleration of orthodontic tooth movement and preservation of the pressure side alveolar bone is 11.0–12.5.
Reconstructions of Cenozoic seafloor ages : Implications for sea level

Accurate estimates of seafloor ages in the recent geological past, will further our understanding of the relationship between mantle dynamics, plate tectonics, and a variety of surficial geological processes. Unfortunately, it is difficult to estimate directly ages for subducted seafloor. Given the near-constancy of surface velocities within a tectonic stage, we can use the relationship between velocity and distance to estimate plate ages for times in the recent past, even for subducted lithosphere. We reconstruct seafloor ages for the entire Cenozoic based on the plate reconstructions and absolute rotation poles of Gordon and Jurdy [1]. For the western Pacific, we explore alternative models based on the reconstructions of Hall [2]. Both reconstructions show an increase in average seafloor age since the early Cenozoic, resulting in an increase in the volume of ocean basins and decreased sea level today. These trends are more pronounced for the Gordon and Jurdy [1] reconstruction because the Hall [2] reconstruction retains older seafloor in the western Pacific, which approximately halves the predicted sea level decrease since the early Cenozoic (250 m vs. 125 m compared to geologic estimates of ~150 m). These changes in sea level occur despite decreases in oceanic lithosphere production rates of only about 20 per cent. Thus, the changing distribution of seafloor age has a larger effect on sea level than changes in spreading rates or ridge lengths. These reconstructions can also be used to estimate the heat flow, the amount of subducted buoyancy and possibly climatic variability associated with factors determined by the age and bathymetry of the oceans, including the carbon cycle.
U-Pb zircon constraints on the age and provenance of the 3 Rocas Verdes basin fill , Tierra del Fuego , Argentina 4

17 [1] The Late Jurassic to Early Cretaceous Rocas Verdes basin constitutes one of the most poorly 18 understood components of the southernmost Andes. As a result, accurate reconstructions and 19 interpretations of deformation associated with the Andean orogeny and the kinematics of Scotia arc 20 development also remain poorly constrained. In this data brief, we report U-Pb zircon ages from 21 sandstones of the Rocas Verdes basin fill and from a crosscutting pluton in the southernmost Andes of 22 Argentine Tierra del Fuego. Detrital samples contain predominant Early to early Middle Cretaceous 23 ( 130–105 Ma) U-Pb zircon age populations, with very small or single-grain middle Mesozoic and 24 Proterozoic subpopulations. A very small subpopulation of Late Cretaceous ages in one sample raises the 25 unlikely possibility that parts of the Rocas Verdes basin are younger than perceived. A sample from a 26 crosscutting syenitic pegmatite yields a crystallization age of 74.7 +2.2/ 2.0 Ma. The data presented 27 herein encourage further geochronologic evaluation of the Rocas Verdes basin in order to better constrain 28 the depositional ages and provenance of its contents.

F IRST DATA ON FEEDING ECOLOGY OF G OSHAWK A CCIPITER GENTILIS DURING THE BREEDING SEASON IN THE N ATURA 2000

This study describes the diet of the Goshwak Accipiter gentilis within littoral ecosystems dominated by pine trees. Samples were collected during the breeding season of 2001 in Dunas de Mira, Gândara e Gafanhas, located in the littoral centre of Portugal and recently included in the Portuguese Natura 2000 network (PTCON 055). Diet composition was assessed from the analysis of 89 pellets and 154 prey remains, collected between the 15 of April and the 25 of July of 2001. Birds represented 86.6% of the total prey items. The remaining prey items were coleoptera (6.5%), mammals (3.6%) and reptiles (3.3%). In terms of biomass birds comprised 90.9%, followed by mammals (7.3%), reptiles (1.7%) and coleoptera (0.05%). Results show that this raptor has a predominantly ornitophagous diet. Domestic pigeon Columba livia var is the most important prey in this area both in terms of frequency and biomass (42.2% and 49.9%, respectively). During the breeding season the diet of the Goshawk is largely connected to Man.
Evaluation of Ultrasound Massage Therapy and Ozone Oil in Management of TMJ Pain Disorders-A Comparative Study

TMJ Disorder refers to a cluster of conditions characterized by pain in the TMJ or its surrounding tissues, functional limitations of mandible or clicking in the TMJ during motion. The main goal of treatment for TMD are to eliminate pain and joint noises and to restore normal mandibular functions1. There are number of therapeutic modalities for TMD includes conservative therapy, cognitive, physicaltherapy, behavioural therapy, pharmacological therapy and intraoral appliances. Various forms of physical therapy intervention, including ultrasound massage therapy (US) and Ozone oil therapy, can be potentially effective for management of TMJ pain disorder.5
The biochemical changes induced by natural human African trypanosome infections

Biochemical evaluation of body fluids gives an indication of the functional state of the various body organs. An evaluation of the biochemical parameters of plasma and cerebrospinal fluid (CSF) in humans infected with Trypanosoma brucei gambiense was carried out. A significant elevation (P<0.01) in the plasma values of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were recorded in study participants, while lowered triglyceride levels (P>0.01) were recorded in the infected participants. The levels of plasma electrolyte recorded were within normal reference intervals. Elevated globulin and decreased albumin levels were recorded in infected study participants. Levels of total protein, total bilirubin, Na, Cl, HCO3 showed no significant increases (P>0.05) during infection. Elevated levels of AST was recorded in the CSF of study participants, the values of CSF enzymes recorded in study were generally lower in trypanosome infected study participants compared to the uninfected participants. Lowered levels of CSF chloride and urea were recorded in the study while the values of potassium, calcium and creatinine in CSF were elevated (P<0.05) in study participants. The results suggest infiltration, inflammation and probable damage of vital body organs resulting from infections with T. b. gambiense.
