A real-time Java chip-multiprocessor

Chip-multiprocessors are an emerging trend for embedded systems. In this article, we introduce a real-time Java multiprocessor called JopCMP. It is a symmetric shared-memory multiprocessor, and consists of up to eight Java Optimized Processor (JOP) cores, an arbitration control device, and a shared memory. All components are interconnected via a system on chip bus. The arbiter synchronizes the access of multiple CPUs to the shared main memory. In this article, three different arbitration policies are presented, evaluated, and compared with respect to their real-time and average-case performance: a fixed priority, a fair-based, and a time-sliced arbiter. Tasks running on different CPUs of a chip-multiprocessor (CMP) influence each others' execution times when accessing a shared memory. Therefore, the system needs an arbiter that is able to limit the worst-case execution time of a task running on a CPU, even though tasks executing simultaneously on other CPUs access the main memory. Our research shows that timing analysis is in fact possible for homogeneous multiprocessor systems with a shared memory. The timing analysis of tasks, executing on the CMP using time-sliced memory arbitration, leads to viable worst-case execution time bounds. The time-sliced arbiter divides the memory access time into equal time slots, one time slot for each CPU. This memory arbitration scheme allows for a calculation of upper bounds of Java application worst-case execution times, depending on the number of CPUs, the time slot size, and the memory access time. Examples of worst-case execution time calculation are presented, and the analyzed results of a real-world application task are compared to measured execution time results. Finally, we evaluate the tradeoffs when using a time-predictable solution compared to using average-case optimized chip-multiprocessors, applying three different benchmarks. These experiments are carried out by executing the programs on the CMP prototype.
Data-sparse approximation to the operator-valued functions of elliptic operator

llIn previous papers the arithmetic of hierarchical matrices has been described, which allows us to compute the inverse, for instance, of finite element stiffness matrices discretising an elliptic operator L. The required computing time is up to logarithmic factors linear in the dimension of the matrix. In particular, this technique can be used for the computation of the discrete analogue of a resolvent (zI - L) -1 , z ∈ C. In the present paper, we consider various operator functions, the operator exponential e -tL , negative fractional powers L -α , the cosine operator function cos(t√L) L-k and, finally, the solution operator of the Lyapunov equation. Using the Dunford-Cauchy representation, we get integrals which can be discretised by a quadrature formula which involves the resolvents (z k I - L) -1 mentioned above. We give error estimates which are partly exponentially, partly polynomially decreasing.
Women Immigrants What is the 'Problem'?

The article questions the dominant image in Swedish society of 'the immigrant woman' as 'the problem'. I argue that this image and the abstract notion of 'the immigrant woman' are socially constructed by the political, economical and ideological apparatus of mainstream society. Research has served power-holders to reinforce, legitimize and manage 'the problem' from an ethnocentric perspective, serving to keep the women at the borders of society and lowest down in worklife hierarchy. By presenting the women as carriers of problematic characteristics mainly defined in cultural terms, mainstream society and employers use the strategy of blaming the victim. I argue instead that subordination in the gendered and ethnically divided labour market, marginalization and invisibility in worklife, are central frames of reality where the actual problems the women meet are being expressed. The challenge facing social scientists and feminist scholars is a redefinition not seeing the women as 'the problem' but defining the problem as generated by structural subordination. The perspective of research must shift from problems defined by power and ethnocentrism to definitions that have their basis in the real life experiences of the women.
Misidentification of Neisseria cinerea as Neisseria meningitidis by Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF MS).

Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is used as a rapid and accurate microbial diagnostic method for species identification of pathogens. At our hospital, we use MALDI-TOF MS for rapid identification of microorganisms from pathogen-positive blood cultures. In this article, we report a case where Neisseria meningitidis was confirmed via blood culture using MALDI-TOF MS, but the microbe was ultimately confirmed to be Neisseria cinerea. The 30-year-old patient received a diagnosis of Burkitt lymphoma, and chemotherapy (R-HyperCVAD/ MA; rituximab, cyclophosphamide, vincristine, doxorubicin, dexamethasone, methotrexate, and cytarabine) was started on day 4 of hospitalization (Day 4). On Day 15, his body temperature rose to 39.2°C without symptoms of a common cold. Two sets of blood cultures were initiated on Day 15, and a Gram-negative coccus was detected in an aerobic bottle on Day 16. The acquisition and analysis of mass spectra were performed on a Microflex LT mass spectrometer (Bruker Daltonics, Bremen, Germany) and using the MALDI Biotyper software package (ver. 3.1) with the reference database ver. 3.1. 2.0 (3,995 database entries) (Bruker Daltonics). The cultivated bacterium was identified as N. meningitidis with Score Value 2.024 (best match) and Score Value 1.966 (second best match). The Score Value 2.024 of this pathogen was lower than that of a known strain, N. meningitidis (Score Value 2.437). Their MALDI-TOF MS spectra showed different wave patterns and peaks between the pathogen isolated from the patient (Fig. 1) and stocked N. meningitidis (Fig. 2). Colony morphology and microscopic morphology were also different between these microbes. The blood culture sediment of the patient showed nonspecific agglutination in a latex agglutination assay (Pastorex Meningitis; Bio-Rad, Hercules, CA, USA). The strain from
In Vitro Screening for Compounds That Enhance Human L1 Mobilization

The Long interspersed element 1 (LINE1 or L1) retrotransposon constitutes 17% of the human genome. There are currently 80–100 human L1 elements that are thought to be active in any diploid human genome. These elements can mobilize into new locations of the genome, resulting in changes in genomic information. Active L1s are thus considered to be a type of endogenous mutagen, and L1 insertions can cause disease. Certain stresses, such as gamma radiation, oxidative stress, and treatment with some agents, can induce transcription and/or mobilization of retrotransposons. In this study, we used a reporter gene assay in HepG2 cells to screen compounds for the potential to enhance the transcription of human L1. We assessed 95 compounds including genotoxic agents, substances that induce cellular stress, and commercially available drugs. Treatment with 15 compounds increased the L1 promoter activity by >1.5-fold (p<0.05) after 6 or 24 hours of treatment. In particular, genotoxic agents (benzo[a]pyrene, camptothecin, cytochalasin D, merbarone, and vinblastine), PPARα agonists (bezafibrate and fenofibrate), and non-steroidal anti-inflammatory drugs (diflunisal, flufenamic acid, salicylamide, and sulindac) induced L1 promoter activity. To examine their effects on L1 retrotransposition, we developed a high-throughput real-time retrotransposition assay using a novel secreted Gaussia luciferase reporter cassette. Three compounds (etomoxir, WY-14643, and salicylamide) produced a significant enhancement in L1 retrotransposition. This is the first study to report the effects of a wide variety of compounds on L1 transcription and retrotransposition. These results suggest that certain chemical- and drug-induced stresses might have the potential to cause genomic mutations by inducing L1 mobilization. Thus, the risk of induced L1 transcription and retrotransposition should be considered during drug safety evaluation and environmental risk assessments of chemicals.
Ages and stratigraphy of mare basalts in Oceanus Procellarum, Mare Nubium, Mare Cognitum, and Mare Insularum

Accurate estimates of mare basalt ages are necessary to place constraints on the duration and the flux of lunar volcanism as well as on the petrogenesis of lunar mare basalts and their relationship to the thermal evolution of the Moon. We performed new crater size-frequency distribution measurements in order to investigate the stratigraphy of mare basalts in Oceanus Procellarum and related regions such as Mare Nubium, Mare Cognitum, and Mare Insularum. We used high-resolution Clementine color data to define 86 spectrally homogeneous units within these basins, which were then dated with crater counts on Lunar Orbiter IV images. Our crater size-frequency distribution measurements define mineralogical and spectral surface units and offer significant improvements in accuracy over previous analyses. Our data show that volcanism in the investigated region was active over a long period of time from ~3.93 to 1.2 b.y. , a total of ~2.7 b.y. Volumetrically, most of the basalts erupted in the Late Imbrian Period between ~3.3 and 3.7 b.y. , and we see evidence that numerous units have been resurfaced. During the Eratosthenian Period, significantly less basalt was erupted. Depending on the absolute model ages that one can assign to the lunar chronostratigraphic systems, five units might be of Copernican age. Younger basalts are generally exposed in the center of the investigated area, that is, closer to the volcanic centers of the Aristarchus Plateau and Marius Hills. Older basalts occur preferentially along the northwestern margin of Oceanus Procellarum and in the southeastern regions of the studied area, i.e., in Mare Cognitum and Mare Nubium. Combining the new data with our previously measured ages for basalts in Mare Imbrium, Serenitatis, Tranquillitatis, Humorum, Australe, and Humboldtianum, we find that the period of active volcanism on the Moon lasted ~2.8 b.y. , from ~4 b.y. to ~1.2 b.y. On the basis of the basalts dated so far, which do not yet include the potentially young basalts of Mare Smythii [e.g., Schultz and Spudis, 1983], we conclude that Oceanus Procellarum not only exhibits the widest range of ages of all investigated basins but probably also is the location of some of the youngest basalts on the lunar surface.
The Marketing of 5-Hydroxytryptamine: Depression or Anxiety?

The discovery that tricyclic antidepressants blocked the re-uptake of both noradrenaline and 5-hydroxytryptamine (5-HT) was a significant step on the road to the development of the monoamine hypotheses of depression (Healy, 1987). The subsequent demonstration that the de-aminated metabolites of amitriptyline and imipramine, nortriptyline and desipramine, were antidepressants tilted the balance toward noradrenaline as the pertinent neurotransmitter, as these latter drugs were clearly inhibitors of noradrenergic rather than 5-HT uptake.
What Is This Thing Called Mental Toughness? An Investigation of Elite Sport Performers

The literature on mental toughness is characterized by a general lack of conceptual clarity and consensus as to its definition, as well as a general failure to operationalize the construct in a consistent manner. This study addressed two fundamental issues surrounding mental toughness: how can it be defined? and what are the essential attributes required to be a mentally tough performer? Ten international performers participated in either a focus group or one-toone interviews, from which a definition of mental toughness and the attributes of the ideal mentally tough performer emerged. The resulting definition emphasized both general and specific dimensions, while the 12 attributes covered self-belief, desire/motivation, dealing with pressure and anxiety, focus (performance-related), focus (lifestyle-related), and pain/hardship factors.
Extracting the Dark Matter Profile of a Relaxed Galaxy Cluster

Knowledge of the structure of galaxy clusters is essential for an understanding of large-scale structure in the universe and may provide important clues to the nature of dark matter. Moreover, the shape of the dark matter distribution in the cluster core may offer insight into the structure formation process. Unfortunately, cluster cores also tend to be the site of complicated astrophysics. X-ray imaging spectroscopy of relaxed clusters, a standard technique for mapping their dark matter distributions, is often complicated by the presence of cool components in cluster cores, and the dark matter profile one derives for a cluster is sensitive to assumptions made about the distribution of this component. In addition, fluctuations in the temperature measurements resulting from normal statistical variance can produce results that are unphysical. We present here a procedure for extracting the dark matter profile of a spherically symmetric, relaxed galaxy cluster that deals with both of these complications. We apply this technique to a sample of galaxy clusters observed with the Chandra X-Ray Observatory and comment on the resulting mass profiles. For some of the clusters we compare their masses with those derived from weak and strong gravitational measurements.
Two-Channel Transparency-Optimized Control Architectures in Bilateral Teleoperation With Time Delay

This paper introduces transparency-optimized control architectures (TOCAs) using two communication channels. Two classes of two-channel TOCAs are found, thereby showing that two channels are sufficient to achieve transparency. These TOCAs achieve a greater level of transparency but poorer stability than three-channel TOCAs and four-channel TOCAs. Stability of the two-channel TOCAs has been enhanced while minimizing transparency degradation by adding a filter; and a combined use of the two classes of two-channel TOCAs is proposed for both free space and constrained motion, which involve switching between two TOCAs for transition between free space and constrained motions. The stability condition of the switched teleoperation system is derived for practical applications. Through the one degree-of-freedom (DOF) experiment, the proposed two-channel TOCAs were shown to operate stably, while achieving better transparency under time delay than the other TOCAs.
Span Programs and General Secure Multi-Party Computation

The contributions of this paper are three-fold. First, as an abstraction of previously proposed cryptographic protocols we propose two cryptographic primitives: homomorphic shared commitments and linear secret sharing schemes with an additional multiplication property. We describe new constructions for general secure multi-party computation protocols, both in the cryptographic and the information-theoretic (or secure channels) setting, based on any realizations of these primitives. Second, span programs, a model of computation introduced by Karchmer and Wigderson, are used as the basis for constructing new linear secret sharing schemes, from which the two above-mentioned primitives as well as a novel verifiable secret sharing scheme can efficiently be realized. Third, note that linear secret sharing schemes can have arbitrary (as opposed to threshold) access structures. If used in our construction, this yields multi-party protocols secure against general sets of active adversaries, as long as in the cryptographic (information-theoretic) model no two (no three) of these potentially misbehaving player sets cover the full player set. This is a strict generalization of the threshold-type adversaries and results previously considered in the literature. While this result is new for the cryptographic model, the result for the information-theoretic model was previously proved by Hirt and Maurer. However, in addition to providing an independent proof, our protocols are not recursive and have the potential of being more efficient.
Social support as a moderator of the relationship between religious participation and psychological distress in a sample of community dwelling older adults

This study investigated relationships among religious participation, social support, and psychological distress within a sample of older adults while controlling for the influence of significant demographic variables. Community-dwelling older adults between the ages of 65 and 90 (n = 115) completed a packet of instruments including the Negative Affect Scale of the PANAS, the Social Provisions Scale (SPS) and a tailored survey that included questions regarding religious participation and demographic variables. Correlational and multiple regression analyses were performed to determine predictors of negative affect. Results indicated that religious participation continued to predict negative affect with the effect of demographic variables statistically controlled for. Subjective social support was also found to moderate the relationship between religious participation and psychological distress. Religious participation appears to be more important regarding alleviating distress for those elderly low in social support compared with those high in social support. Religious participation may thus occupy an important position with regards to factors that manage psychological distress among elderly individuals, particularly for those low in social support.
Self‐efficacy and Student Performance in an Accounting Course

Self‐efficacy has been defined as individuals’ beliefs, thoughts, and feelings about their personal capabilities that affect how they function and, which in turn influence their performance (Bandura 1977). Self beliefs can influence behaviour choices, determine the amount of effort needed and for how long, and encourage thought patterns and emotional behaviours necessary to succeed. It is theorised that students with unrealistic expectations (especially overly optimistic expectations) may have difficulty aligning efforts with desired performance levels and, as a result, perform more poorly. In this study, selfefficacy is operationalised as the difference between actual and predicted examination performance. Prediction errors in the final examination marks (MERR) and prediction error in the overall course grade (GERR) of a second year management accounting course are used as measures of Self‐efficacy. Using regression analysis, the results indicate that the efficacy measures are significant and positively related to course performance. This suggests that students who are more conservative in their expectations of the course results perform better than those who are more optimistic. The findings also showed that student characteristics of previous academic achievements (CGPA) and hours of study per week (HRWK) explained more that 40 per cent of the variations in the self‐efficacy measures. The higher a student’s CGPA, the more conservative or cautious he is in the prediction of his final course performance. The more pessimistic a student is of his final course performance, the lower the number of hours he estimates for studying the course.
Joint Responsibility

The career literature advocates a joint person-organization responsibility for the career development of employees. Along similar lines, this study explored the relationships between individual and organizational career management and employee career effectiveness. The results indicated that two elements of individual career management—planning and proactivity—contributed to career effectiveness. Perceived organizational career management enhanced the affective aspects of career effectiveness (career attitudes and identity) and was also associated with personal planning. The study lends support to an implicit, untested, and widely shared assumption regarding the contribution of organizational career management to individual effectiveness.
Comparison of a ‘two-bag system’ versus conventional treatment protocol (‘one-bag system’) in the management of diabetic ketoacidosis

Objective We compared the conventional ‘one-bag protocol’ of management of diabetic ketoacidosis (DKA) with the ‘two-bag protocol’ which utilizes two bags of fluids, one containing saline and supplemental electrolytes and the other containing the same solution with the addition of 10% dextrose. Research design and methods A retrospective chart review and analysis was done on adult patients admitted for DKA to the Riverside University Health System Medical Center from 2008 to 2015. There were 249 cases of DKA managed by the one-bag system and 134 cases managed by the two-bag system. Results The baseline patient characteristics were similar in both groups. The anion gap closed in 13.56 hours in the one-bag group versus 10.94 hours in the two-bag group (p value <0.0002). None of the individual factors significantly influenced the anion gap closure time; only the two-bag system favored earlier closure of the anion gap. Plasma glucose levels improved to <250 mg/dL earlier with two-bag protocol (9.14 vs 7.82 hours, p=0.0241). The incidence of hypoglycemic events was significantly less frequent with the two-bag protocol compared with the standard one-bag system (1.49% vs 8.43%, p=0.0064). Neither the time to improve serum HCO3 level >18 mg/dL nor the hospital length of stay differed between the two groups. Conclusions Our study indicates that the two-bag protocol closes the anion gap earlier than the one-bag protocol in adult patients with DKA. Blood glucose levels improved faster with the two-bag protocol compared with the one-bag protocol with fewer associated episodes of hypoglycemia. Prospective studies are needed to evaluate the clinical significance of these findings.

Rumination and intentional forgetting of emotional material

The tendency to respond to negative life events and negative mood states with ruminative thinking has been linked to emotion dysregulation and to a heightened risk for the onset and maintenance of emotional disorders. To further investigate this maladaptive response style, the present study examined whether rumination is linked to individual differences in the ability to intentionally forget emotional material. In a directed forgetting task, participants were instructed to memorise a list of positive and negative words and were subsequently told to forget these words. Next, participants were told to memorise a new list and, finally, recall was tested for all to-be-forgotten and to-be-remembered words. Our results demonstrate a close relation between rumination and recall in the forget condition but not in the remember condition. Specifically, compared to participants who scored low on the Ruminative Responses Scale (RRS), participants who scored high exhibited reduced forgetting of positive and negative to-be-forgotten words. These results remained stable when depression scores were included as a covariate suggesting that irrespective of depressive symptoms, rumination and intentional forgetting of emotional material are closely related.
