Force correlations, anisotropy, and friction mobilization in granular assemblies under uniaxial deformation

We study dense, frictional, polydisperse 3D granular assemblies under uniaxial deformation with Discrete Element Method (DEM) simulations. The overall goal – beyond the scope of the present study – is to link microscopic parameters and observations with the macroscopic behavior, for different elementary deformation modes. At present, we focus on the behavior of the force/contact network during uniaxial deformation, for different coefficients of friction. We discuss the stress and structural anisotropy and the relationship between force intensity weighted by contact state (sticking or sliding, at the Coulomb limit) or force strength. Furthermore, we study the orientational distribution of contacts and forces and the contribution of friction to structural anisotropy. We find that initial isotropic states are irrecoverable, since the structural anisotropy is independent of the deviatoric stress behavior both with and without friction. Contacts display an interesting anisotropy of order four in the presence of friction.

Methodological rigor of corporate governance studies: A review and recommendations for future studies

Abstract Manuscript Type Article/Review Research Question/Issue This study presents the results of a longitudinal content analysis of governance articles published in both CGIR and other leading management outlets. Our aim with this review is to identify problematic areas, as well as opportunities to improve the methodological rigor of governance studies. Research Findings/Insights We examine key design aspects of corporate governance articles. We identify and compare trends (1) over time and (2) across publishing outlets. Specifically examined are the geographic scope of samples, design characteristics (i.e., single‐ versus multi‐year data, the use of archival, survey, experimental, and qualitative designs, data sources, and reliance on concurrent versus longitudinal data), survey response rates and the use of tests for non‐response bias, the statistical analysis techniques used, reporting of results (number and proportion of hypotheses supported, non‐significant, and counter‐significant, use of statistical power analysis, reporting of descriptive statistics and correlations, use and significance of control variables, and endogeneity controls), and the sophistication of the models tests (i.e., mediation and moderation). Theoretical/Academic Implications Based on the results of the review, recommendations for academic researchers are offered in the following areas: (1) designing theoretical tests which both incorporate and go beyond main effects; (2) evaluating a research design's analytical parameters on an a priori basis to maximize reliability, validity, and the potential for publication; (3) incorporating assessment of sensitivity and robustness checks into the analysis; and (4) comprehensive reporting of results including post hoc power analysis, complete and expanded correlation matrix(es), reporting and assessing counter‐results, and avoiding HARKing.

Shall we dance? - An empirical analysis of management team in LBO syndication

In this paper, we investigate how management team characteristics might influence LBO syndication decision, which might be able to alleviate risks and uncertainties arising from the pre-deal screening and the post-deal value-added services. By using a unique hand-collected dataset, we find that investment size and geographic distance matter for syndication decision. Moreover, management teams dominated by consulting experience and higher homogeneity in education background are prone to syndication. In contrast, teams dominated by business degrees are not.

Motivations for enterprise system adoption in transition economies: insights from Poland

Enterprise system (ES) adoption can bring many benefits, but may also put tremendous strain on an organisation or business, sometimes with disastrous outcomes. The specific motivations and expectations that lead to ES adoption may impact the success or failure of these endeavours, and understanding these motivations may be useful in predicting the success of ES projects. Most of the published research on ES adoption motivation has been in the context of highly developed countries. The social, cultural, economic and political conditions in developing, emerging and transition economies make for a different business environment, and insights obtained from developed countries may not always transfer to these settings. This study seeks to identify and help understand the motivations for ES adoption specifically in transition economies, as these economies play a significant role in the global market, but have not been receiving adequate research attention. Drawing on the experience of 129 ES adopters in Poland, a transition economy, this study categorises motivations into coherent groups of issues and evaluates the influence of discovered motivations on ES adoption success. Further, motivations revealed by this study are compared with motivations reported by prior research conducted in developed countries.

Cold sensor, hot topic: TRPM8 plays a role in monocyte function and differentiation

Abstract Understanding the innate immune system and how aberrant activation or impaired inhibition leads to the development of hyperinflammatory conditions, including inflammatory bowel disease, is crucial for patient management and treatment. An emerging area of interest surrounding dysregulated inflammation focuses on membrane bound transient receptor potential (TRP) ion channels. These channels are permeable to calcium and other cations involved in the balance of leukocyte membrane potential and function, as well as afferent neuron signaling within the myenteric plexus of the GI tract, bladder, and skin. A particular channel, TRPM8, is an important cell surface marker for prostate cancer and participates in the function of cold sensing neurons. Specifically, this ion-gated receptor is shown to be activated by agonists such as menthol and eucalyptus, which aid in the soothing, cooling effects of these agents. Furthermore, the TRPM8 channel is also identified on the surface of resident tissue Mϕs and is also linked to the protective role and release of calcitonin gene-related peptide (CGRP) by sensory neurons.

Analysis of Power Transactions on the Integrated Solar Home System

Recently, renewable energy has become a popular natural resource to replace the fossil energy. So that its presence is increasingly being explored for use as a power plant. Solar energy is the most desirable and many methods are developed to capture the energy coming from the sun and convert it. The conversion process that is often encountered is by using solar cells. With the development of solar cell technology, more and more solar home systems (SHS) are being used based on the utilization of solar energy in load centers. SHS integrated into the electricity network is also increasingly connected to the system, so that it will have an impact on the performance of all three power transactions in progress. Therefore, in this study, the integration is evaluated using the financial value for each transaction based on energy exports and imports between customers and providers. The results show this has been done on the export-import of electricity during the customer's electricity consumption process, and the integration of SHS also contributes to the balance of the existing power stock. In addition, taking into account customer profiles, it can be seen that consumers have a profit of 14% customers 1, 15% customers 2, and 24% customers 3.

Large-scale restricted boltzmann machines on single GPU

Recent works on deep belief network (DBNs) have shown that applying large-scale unsupervised feature learning model can dramatically improve the performance of the applications in many fields. Training billions of parameters in these models such as restricted boltzmann machines (RBMs) appears to be computational challenging for modern CPUs. Graphical Processing Units (GPUs) has been employed in many large-scale deep learning models for performance enhancement due to its massively parallel computing capability. Unfortunately, the limited device memory of GPUs imposes a restriction on the size of the model trained on a single GPU. Multi-GPUs approaches, on the other hand, suffer from inefficient communication and economic cost. In this paper, we proposed a novel memory efficient algorithm on single GPU that can train large-scale RBMs without size restriction and preserve the performance gain of GPU parallel computation. Particularly, the experiments demonstrated that our approach used 75% less memory storage at the cost of only 10% performance loss in training large-scale RBMs with billions of parameters.

Grounding Debates about Land

Solomon Islands has often been seen as exemplifying wider concerns regarding customary land tenure, economic development and political instability in the southwest Pacific. Locals express concern regarding inequality in land control at multiple scales, while aid donors urge people to register land as a means to increase legal certainty, build peace and render land more ’marketable’. This chapter situates debates about land in Solomon Islands within wider global debates regarding customary tenure, gender inequality and state regulation. It highlights a long-standing divide in feminist debates, between those who perceive land tenure in terms of a hierarchically ordered and gendered ‘bundle of rights’, and those who perceive land as subject to fluid, negotiable claims. Drawing insights from legal geography, political ecology and feminist scholarship on legal pluralism, it suggests that a focus on the ways in which ‘access’ to resources is transformed into state-sanctioned ‘property’ recognises that property is negotiable while also highlighting factors that contribute to inequality. This approach also directs attention to the role of scholars in the formation of property.

Morphometric analysis of muscle fibre types in rat locomotor and postural skeletal muscles in different stages of chronic kidney disease.

Muscle weakness and progressive loss of skeletal muscle mass are serious complications of chronic kidney disease (CKD). The pathogenesis of this condition is still poorly understood. The study investigated fibre type distribution and diameter in functionally different skeletal muscles: locomotor, gastrocnemius muscle (MG) and postural, longissimus thoracis muscle (ML) together with an evaluation of metabolic disturbances and nutritional parameters of rats with different stages of CKD. Wistar rats were randomized to a sham operation - CON, uninephrectomy - CKD1/2 or subtotal nephrectomy - CKD5/6. After 4 weeks, serum concentration haemoglobin (Hb), haptoglobin (Hp), MCP-1, advanced glycation end products (AGEs), and homocysteine (Hcy) were measured. Muscle specimens were stained for myofibrillary ATPase and NADH-diaphoreses activity according to Ziegan's method. There was a significant increase in the percentage of IID/X with a concomitant decrease of IIB fibres in ML in CKD1/2 vs. CON and CKD5/6. IIB fibre diameters in ML were smaller (53.4±7.3 vs. 58.1±8.1 and 59.8±11.2; p=0.08) for CKD5/6 vs. CKD1/2 and CON, respectively. There were significant differences for CKD5/6 and CKD1/2 vs. CON in: Hb (11.4±3.1; 13.7±0.7 and 14.1±1 g/dl), Hp (1.6±0.6; 1.6±0.6 and 0.7±0.4 mg/ml), AGEs (5.1±0.6; 4.3±1.2 and 4.6±0.9 AU), Hcy (7.2±1.2; 5.1±0.5 and 4.9±0.5 M), MCP-1 (609±255; 489±265 and 292±113 pg/ml), respectively. We concluded that early stages of CKD could induce the process of compensatory fast to slow fibre transformation, while in more advanced CKD this process may be blocked and atrophy of fast-twitch fibres may occur, predominantly in non-locomotor muscles. These disturbances can be secondary to CKD-related metabolic burden and inflammation.

Learning complex historical knowledge at high school: The role of working memory (*)

Learning History implies the acquisition of historical and social concepts, analyzing its mutual relationships in the explanation of historical change. The comprehension of Industrial Revolution in England requires the use of at least four main concepts: Agrarian Revolution, Demographic Increase, Technological Innovations and the need of Accumulated Capital. The understanding of these concepts and the establishment of its relationships is a quite demanding cognitive task. Therefore, the crucial role of working memory in these cognitive processes is hypothesized. This paper presents a study on the teaching and learning of this subject matter by first-grade of high school subjects. The main objective of this study was to analyze the process of understanding and acquisition of this complex subject, testing the influence of three variables: working memory capacity, prior knowledge and attitude for meaningful learning. Pretest examined subject's knowledge of some basic concepts and their ability to describe and explain the phenomenon, as well as to summarize and comment a text and to represent their knowledge by means of a concept map. Differences in working memory capacity were controlled by means of the reading span test. Finally, subject's attitude for meaningful learning was tested on line using an observation record. Teaching was developed during 6 classes following the usual scheme and methodology focused on reaching a gradual and overall understanding of the phenomenon. Learning results were checked in a post-test where we used the same test than before. There was a highly significant increase in all the post-test measures. Students with higher reading span learnt more and better than students with lower reading span. Therefore, working memory seems to play a crucial role when our subjects are building up historical knowledge as to Industrial Revolution. The significant correlation between knowledge in pretest and post-test showed that pretest scores are a quite good predictor of post-test ones, as all the cognitive theories held. As to the attitude, its high correlation with both knowledge measures (pre and post-test) bears out our prediction about the relevant role of this variable. Finally the analysis of subjects concept maps in pretest and post-test confirmed an improvement on subjects' organization of knowledge, increasing its levels of depth and connectivity.

Demonstration of a room temperature 2.48–2.75 THz coherent spectroscopy source

We report the first demonstration of a continuous wave coherent source covering 2.48–2.75 THz, with greater than 10% instantaneous tuning bandwidth and having 1–14 μW of output power at room temperature. This source is based on a 91.8–101.8 GHz synthesizer followed by a power amplifier and three cascaded frequency triplers. It demonstrates for the first time that purely electronic solid-state sources can generate a useful amount of power in a region of the electromagnetic spectrum where lasers (solid state or gas) were previously the only available coherent sources. The bandwidth, agility, and operability of this THz source have enabled wideband, high resolution spectroscopic measurements of water, methanol, and carbon monoxide with a resolution and signal-to-noise ratio unmatched by any other existing system, providing new insight in the physics of these molecules. Furthermore, the power and optical beam quality are high enough to observe the Lamb-dip effect in water. The source frequency has an absolute accuracy better than 1 part in 1012 and the spectrometer achieves sub-Doppler frequency resolution better than 1 part in 108. The harmonic purity is better than 25 dB. This source can serve as a coherent signal for absorption spectroscopy, a local oscillator for a variety of heterodyne systems and can be used as a method for precision control of more powerful but much less frequency agile quantum mechanical terahertz sources.

Acute Hepatotoxicity of <i>Pseudomonas aeruginosa</i> Exotoxin A in Mice Depends on T Cells and TNF

Abstract The most potent virulence factor of Pseudomonas aeruginosa, its exotoxin A (PEA), inhibits protein synthesis, especially in the liver, and is a weak T cell mitogen. This study was performed to correlate hepatotoxic and possible immunostimulatory features of PEA in vivo. Injection of PEA to mice caused hepatocyte apoptosis, an increase in plasma transaminase activities, and the release of TNF, IFN-γ, IL-2, and IL-6 into the circulation. Most strikingly, liver damage depended on T cells. Athymic nude mice or mice depleted of T cells by anti-Thy1.2 mAb pretreatment failed to develop acute hepatic failure, and survival was significantly prolonged following T cell depletion. Neutralization of TNF or lack of TNF receptors prevented liver injury. In the liver, TNF was produced by Kupffer cells before hepatocellular death occurred. After T cell depletion, Kupffer cells failed to produce TNF. Transaminase release was significantly reduced in perforin knockout mice, and it was even elevated in lpr/lpr mice. These results demonstrate that PEA induces liver damage not only by protein synthesis inhibition but also by TNF- and perforin-dependent, Fas-independent, apoptotic signals.

Culture, Gender, and Men's Intimate Partner Violence

Abstract This article reviews research on cultural beliefs and expectations about gender and romantic relationships that are related to male intimate partner violence. We link beliefs about men (manhood is tenuous and must be proven, men must protect women, and honor must be defended), about women (good women put sacrifice and family loyalty first and good women are morally and sexually pure), and about relationships (jealousy is a sign of passionate love) to show how they create a cultural context in which intimate partner violence is tolerated, accepted, or rejected. We end by discussing avenues for future research that take an expansive approach to examining culture's influence on intimate violence.

Evaluation of antioxidant and antibacterial activities of some selected seaweeds from Saint Martin's Island of Bangladesh

The effects of extracting solvents on the antioxidant and antibacterial activity of crude extracts of six seaweeds were investigated. The antioxidant activity of seaweed crude extracts was evaluated by total antioxidant activity (TAA), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt (ABTS), and cupric reducing antioxidant capacity (CUPRAC) assays. Acetone extract of B. wrightii showed significantly (P < 0.05) the highest total phenolic content (TPC) (71.09 mg GAE/g), while methanolic extract of Porphyra sp. had the highest total flavonoid content (75.61 mg QE/g). Methanolic extract of S. muticum showed significantly (P < 0.05) the highest TAA. Methanolic extract of P. tetrastromatica and S. muticum showed significantly (P < 0.05) the highest DPPH and ABTS radical scavenging effects, while acetone extract of B. wrightii showed significantly the highest ECA0.50 value (0.78 mg/ml) of CUPRAC activity. Pearson's correlation test and principal component analysis (PCA) confirmed the relationship between TPC and various antioxidant activity assays of seaweed extracts. Methanolic extracts of P. tetrastromatica, S. muticum and H. clathratus showed higher inhibitory zones against all the bacterial strains than other seaweed extracts. The results of this study indicated that brown seaweeds showed comparatively better antioxidant and antibacterial activity, which could be utilized in the food processing industries.
