Symmetric capacity of nonlinearly modulated finite alphabet signals in MIMO random channel with waveform and memory constraints

The paper shows a procedure for evaluating the symmetric ergodic capacity of nonlinearly modulated finite alphabet signals in the MIMO random channel. We first investigate informationally an equivalent signal space representation for finite alphabet signals. The signals are allowed to be multidimensional per one antenna to reflect the modulation nonlinearity. The informationally equivalent signal space representation allows a factorization per one eigenmode (depending purely on one marginal eigenvalue) in the capacity evaluation in the MIMO channel. The evaluation complexity does not depend on the MIMO dimensions. We consider two types of channel signal constraints. (1) A constraint on the waveform only. (2) A constraint on the waveform and memory (modeled as a Markov chain). The mean symmetric capacity for the former one is derived. For the latter one, we derive lower and upper bounds based on the entropy rate approximation.
Diagnosis of repeated failures for discrete event systems with linear-time temporal-logic specifications

In our earlier work, we introduced a state-based approach for the diagnosis of repeatedly occurring failures in discrete event systems (DESs). Since temporal logic provides a simpler way of specifying system properties; in this paper, a temporal-logic-based approach for diagnosing the occurrence of a repeated number of failures is developed. Linear-time temporal-logic (LTL) formulae are used to represent the specifications of DESs. Notions of prediagnosability for failures and diagnosability for repeated failures are introduced in the setting of temporal logic. A polynomial algorithm for the test of prediagnosability for failures is provided. The diagnosis problem for repeated failures in the temporal-logic setting is reduced to one in a state-based setting, and so the prior results of a state-based repeated failure diagnosis can be applied. Finally, a simple example is given for illustration. Note to Practitioners-Certain failures in a system are repeatable, such as routing errors in a manufacturing system. A theory for the diagnosis of such failures was presented in an earlier work of Jiang et al. The present paper uses temporal logic to specify such failures. It turns out that repeatable failures can be specified as violations of invariant properties (i.e., properties that must always hold). Given an invariant property that the system must always satisfy, an algorithm is presented to refine the system model and label those states of the refined system where the property is violated. The problem of repeated diagnosis then requires determining, within a bounded delay, each time a "failure-state" is visited. For this analysis, the existing theory developed by Jiang et al. is used.
Explaining the Role of Trust in Cloud Service Acquisition

Effective digital identity management system is a critical enabler of cloud computing, since it supports the provision of the required assurances to the transacting parties. Such assurances sometimes require the disclosure of sensitive personal information. Given the prevalence of various forms of identity abuses on the Internet, a re-examination of the factors underlying cloud services acquisition has become critical and imperative. In order to provide better assurances, parties to cloud transactions must have confidence in service providers' ability and integrity in protecting their interest and personal information. Thus a trusted cloud identity ecosystem could promote such user confidence and assurances. Using a qualitative research approach, this paper explains the role of trust in cloud service acquisition by organizations. The paper focuses on the processes of acquisition of cloud services by financial institutions in Ghana. The study forms part of comprehensive study on the monetization of personal Identity information.
Hepatic carcinogenesis in thyroidectomized rats: apparent blockade at the stage of initiation.

The protective effect of thyroidectomy against the induction of liver tumors by 2-aminofluorene in rats is confirmed. Evidence is presented indicating that the effect of thyroidectomy may be attributable to blockade of liver carcinogenesis at or before the stage of initiation rather than to retardation of tumor progression in such animals.

Neuroprotective Signaling Mechanisms of Telomerase Are Regulated by Brain-Derived Neurotrophic Factor in Rat Spinal Cord Motor Neurons

Telomerase can promote neuron survival and can be regulated by growth factors such as brain-derived neurotrophic factor (BDNF). Increases of BDNF expression and telomerase activity after brain injury suggest that telomerase may be involved in BDNF-mediated neuroprotection. We investigated BDNF regulation of telomerase in rat spinal cord motor neurons (SMNs). Our results indicate that BDNF increases telomerase expression and activity levels in SMNs and activates mitogen-activated protein kinase/extracellular signal-regulated kinases 1 and 2 and phosphatidylinositol-3-OH kinase/protein kinase B signals, and their downstream transcription factors nuclear factor-&kgr;B, c-Myc, and Sp1. Administration of the tyrosine kinase receptor B inhibitor K-252a, the mitogen-activated protein kinase 1 inhibitor PD98059, and the phosphatidylinositol-3-OH kinase inhibitor LY294002 abolished BDNF-induced upregulation of these transcription factors and telomerase expression. The nuclear factor-&kgr;B inhibitor Bay11-7082 also attenuated c-Myc and Sp1 expression and increased telomerase promoter activity. Spinal cord motor neurons with higher telomerase levels induced by BDNF became more resistant to apoptosis; survival of SMNs that overexpressed the catalytic protein component of telomerase with reverse transcriptase activity was also enhanced against apoptosis. The neuronal survival-promoting effect of telomerase was mediated through the regulation of Bcl-2, Bax, p53, and maintenance of mitochondrial membrane potential. Taken together, these data suggest that the neuroprotective effect of BDNF via telomerase is mediated by inhibition of apoptotic pathways.
Power and Channel Allocation for Non-Orthogonal Multiple Access in 5G Systems: Tractability and Computation

A promising multi-user access scheme, non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC), is currently under consideration for 5G systems. NOMA allows more than one user to simultaneously access the same frequency-time resource and separates multi-user signals by SIC. These render resource optimization in NOMA different from orthogonal multiple access. We provide theoretical insights and algorithmic solutions to jointly optimize power and channel allocation in NOMA. We mathematically formulate NOMA resource allocation problems, and characterize and analyze the problems' tractability under a range of constraints and utility functions. For tractable cases, we provide polynomial-time solutions for global optimality. For intractable cases, we prove the NP-hardness and propose an algorithmic framework combining Lagrangian duality and dynamic programming to deliver near-optimal solutions. To gauge the performance of the solutions, we also provide optimality bounds on the global optimum. Numerical results demonstrate that the proposed algorithmic solution can significantly improve the system performance in both throughput and fairness over orthogonal multiple access as well as over a previous NOMA resource allocation scheme.
Ricci iterations on Kähler classes

Abstract In this paper we consider the dynamical system involved by the Ricci operator on the space of Kähler metrics of a Fano manifold. Nadel has defined an iteration scheme given by the Ricci operator and asked whether it has some non-trivial periodic points. First, we prove that no such periodic points can exist. We define the inverse of the Ricci operator and consider the dynamical behaviour of its iterates for a Fano Kähler–Einstein manifold. Then we define a finite-dimensional procedure to give an approximation of Kähler–Einstein metrics using this iterative procedure and apply it on ℂℙ2 blown up in three points.
Association of PON1, P2Y12 and COX1 with Recurrent Ischemic Events in Patients with Extracranial or Intracranial Stenting

Background and Purpose Short-term combined use of clopidogrel and aspirin improves cerebrovascular outcomes in patients with symptomatic extracranial or intracranial stenosis. Antiplatelet non-responsiveness is related to recurrent ischemic events, but the culprit genetic variants responsible for the non-responsiveness have not been well studied. We aimed to identify the genetic variants associated with poor clinical outcomes. Methods Patients with symptomatic extracranial or intracranial stenosis scheduled for stenting and receiving dual antiplatelets (clopidogrel 75 mg and aspirin 100 mg daily) for at least 5 days before intervention were enrolled. Ischemic events including recurrent transient ischemic attack, stroke, myocardial infarction, and vascular-related mortality within 12 months follow-up were recorded. We examined the influence of genetic polymorphisms on treatment outcome in our patients. Results A total of 268 patients were enrolled into our study and ischemic events were observed in 39 patients. For rs662 of paraoxonase 1 (PON1), allele C was associated with an increased risk of ischemic events (OR = 1.64, 95%CI = 1.03–2.62, P = 0.029). The A-allele carriers of rs2046934 of P2Y12 had a significant association with adverse events (OR = 2.01, 95%CI = 1.10–3.67, P = 0.041). The variant T-allele of cyclooxygenase-1 (COX1) rs1330344 significantly increased the risk of recurrent clinical events (OR = 1.85, 95%CI = 1.12–3.03, P = 0.017). The other single nucleotide polymorphism (SNP) had no association with ischemic events. Conclusions PON1, P2Y12 and COX1 polymorphisms were associated with poorer vascular outcomes. Testing for these polymorphisms may be valuable in the identification of patients at risk for recurrent ischemic events.
The EGL-21 Carboxypeptidase E Facilitates Acetylcholine Release at Caenorhabditis elegans Neuromuscular Junctions

Proneuropeptides are packaged into dense-core vesicles in which they are processed into active peptides by copackaged enzymes. Proprotein convertases (PCs) cleave precursors after dibasic residues, and carboxypeptidases remove basic residues from the C terminals. We show here that the Caenorhabditis elegans egl-21 gene encodes a protein that is very similar to carboxypeptidase E (CPE) and is broadly expressed in the nervous system. Mutants lacking either egl-21 CPE oregl-3, which encodes the C. elegansortholog of PC type 2 (PC2), were defective for processing endogenously expressed FMRFamide (Phe-Met-Arg-Phe-NH2)-related peptides (FaRPs). Mutants lacking the unc-104 kinesin motor protein were defective for anterograde movement of dense-core vesicle components, including egl-3 PC2, egl-21 CPE, and FaRPs. We provide evidence that egl-3 PC2 andegl-21 CPE mutants have diminished acetylcholine release at neuromuscular junctions (NMJs). Taken together, these results suggest that egl-21 CPE and egl-3 PC2 process endogenous neuropeptides that facilitate acetylcholine release at C. elegans NMJs.
Adolescents' perceptions of environmental influences on physical activity.

OBJECTIVES To examine African American adolescents' perceptions of environmental influences on physical activity and identify physical activity promotion strategies. METHODS Concept mapping with 50 adolescents was used to obtain cluster maps of conceptual domains affecting physical activity. RESULTS Seven domains were identified, including physical activity settings, social support, negative social influences, parental control, negative environmental influences, transportation and technology issues, and financial issues. Their relative importance to physical activity varied by gender. CONCLUSIONS This research identified salient environmental characteristics that can be measured in future studies as well as strategies for increasing physical activity in urban youths.
Modulation Techniques for Communication via Diffusion in Nanonetworks

Communication via diffusion of molecules is an effective method for transporting information in nanonetworks. In this paper, novel modulation techniques called Concentration Shift Keying (CSK) and Molecule Shift Keying (MSK) are proposed for coding and decoding information of the so-called messenger molecule concentration waves in nanonetworks. The first technique, CSK, modulates the information via the variation in the concentration of the messenger molecules whereas MSK utilizes different types of messenger molecules to represent the information. Using simulation, the performance of these modulation techniques is evaluated in terms of susceptibility to noise and transmission power requirements. The new techniques achieve high channel capacity values, in particular, the MSK technique exhibits more robustness against noise and requires less power.
Fusicoccin signaling reveals 14-3-3 protein function as a novel step in left-right patterning during amphibian embryogenesis

To gain insight into the molecular mechanisms underlying the control of morphogenetic signals by H+ flux during embryogenesis, we tested Fusicoccin-A (FC), a compound produced by the fungus Fusicoccum amygdali Del. In plant cells, FC complexes with 14-3-3 proteins to activate H+ pumping across the plasma membrane. It has long been thought that FC acts on higher plants only; here, we show that exposing frog embryos to FC during early development specifically results in randomization of the asymmetry of the left-right (LR) axis (heterotaxia). Biochemical and molecular-genetic evidence is presented that 14-3-3-family proteins are an obligate component of Xenopus FC receptors and that perturbation of 14-3-3 protein function results in heterotaxia. The subcellular localization of 14-3-3 mRNAs and proteins reveals novel cytoplasmic destinations, and a left-right asymmetry at the first cell division. Using gain-of-function and loss-of-function experiments, we show that 14-3-3E protein is likely to be an endogenous and extremely early aspect of LR patterning. These data highlight a striking conservation of signaling pathways across kingdoms, suggest common mechanisms of polarity establishment between C. elegans and vertebrate embryos, and uncover a novel entry point into the pathway of left-right asymmetry determination.
The City God Returns: Organised and Contagious Networks at the Xiamen City God Temple

This paper explores the revival and current networks of the Xiamen City God temple in Southeast China. I divide the networks into two forms: the first is organised and composed of systematically and consciously structured networks; the second is contagious, made up of networks that are more unwieldy and impossible to fully map as they are formed through the affective intensity of ritual events. The two forms of networks are mutually dependent: without the donations and participation generated through organised networks, the ritual events would never take place; without the ritual events that generate networks of contagion, there would be no interest or reason to support the temple and the god’s efficacy would be seen in decline.
A Comparative Analysis of Media Coverage of Mass Public Shootings: Examining Rampage, Disgruntled Employee, School, and Lone-Wolf Terrorist Shootings in the United States

This study provides a comparative analysis of news media coverage across four types of mass public shootings: rampage, disgruntled employee, school, and lone-wolf terrorist. This research analyzes the agenda-setting function of the media and identifies differences in coverage and the salience of coverage, proportionality of coverage, changes in coverage over time, and factors influencing levels of coverage. Findings indicate school shootings and lone-wolf terrorist shootings receive disproportionate amounts of news media coverage. This suggests media coverage may be contributing to setting the public and policy agenda concerning the phenomenon. These findings have important implications for public perceptions of risk, conceptualizations of potential perpetrators, and the implementation of security measures.
A Comparative Review of Caring Thinking and Its Implications on Teaching and Learning

Purpose – This paper undertakes a comparative review of the concept of ‘Caring Thinking’ from the perspectives of specific scholars (with different cultural voices) in the field of Educational Psychology. Specifically, it focuses on the area of Thinking and Cognition.Methodology – The review scrutinised the concept of caring thinking in Matthew Lipman’s (2003) Thinking Model as well as Mohd Daud Hamzah and Abdul Kadir Arifin’s (2001) Islamic Cognitive Processes Model (ICPM). Employing a cross-cultural comparative review, the analysis concentrated on the commonalities shared and the differences between the two schools of thought.The aspects of comparison included cognition principles, caring thinking inventory, thinking direction, human characterisation and role of beings.Findings – This review suggests that the scholars propagate and share comparable nuances on the underlying characteristics of human cognition in order to facilitate the formation of the caring thinking concept. However, the interplay of human inner drive which incorporates values is deliberated in different cultural voices. While Lipman (2003) vastly discusses the caring thinking model based on the western context, Mohd Daud Hamzah and Abdul Kadir Arifin’s (2001) cognition model attempts to highlight human cognitive process from an Islamic perspective.Significance – These findings suggest the need to understand the derivation of human cognition processes, that further explains the ability to sense bad and good values in moral virtue development. Fundamentally, this discussion considers the perspectives of both models regarding the formation of an individuals’ thoughts and behaviours, which reflect the attributes of ‘caring thinking’. It implies that greater effort should be undertaken to explore how caring thinking can be made useful to the field of education.
