Adaptive QoS routing for significant events in wireless sensor networks

Wireless sensor networks (WSN) can report large volumes of slowly varying routine data, while important or significant events can be relatively rare. An important challenge is then to offer the significant or unusual data an adequate routing policy that will allow it to rapidly reach the sink nodes, despite the large volume of routine packets in the network. In this paper we introduce randomized re-routing (RRR), to detect the unusual events in a distributed manner, and dynamically transfer routine data packets to secondary paths in the network, while offering a fast track path with better QoS for the packets carrying unusual data. In this paper we describe the RRR algorithm and evaluate it with extensive simulations.
Health Outcomes in Poor Countries and Policy Options: Empirical Findings from Demographic and Health Surveys

Empirical studies on health at a disaggregate level-by socioeconomic group or geographic location-can provide useful information for designing poverty-focused interventions. Using Demographic and Health Survey (DHS) data, the author investigates the determinants of health outcomes in low-income countries both at the national level, and for rural and urban areas separately. DHS data from more than 60 low-income countries between 1990 and 1999 reveal two interesting observations. First is the negative association between the level and inequality in child mortality. Second is the significant gap in child mortality between urban and rural areas, with the rural population having a much slower reduction in mortality compared with the urban population. Given that the poor are mainly concentrated in rural areas, the evidence suggests that health interventions implemented in the past decade may not have been as effective as intended in reaching the poor. The empirical findings in this study consolidate results from earlier studies and add new evidence. the author finds that at the national level access to electricity, vaccination in the first year of life, and public health expenditure can significantly reduce child mortality. The electricity effect is shown to be independent of income. In urban areas only access to electricity has a significant health impact, while in rural areas increasing vaccination coverage is important for mortality reduction.
The applicability of DMO / AMO in the presence of caustics

Reflection seismic data continuation is the computation of data at source and receiver locations that differ from those in the original data, using what data are available. Here, we develop a general theory of data continuation in the presence of caustics and illustrate it with two examples: dip moveout (DMO) and azimuth moveout (AMO). This theory does not require knowledge of the reflector positions. We construct the output data set from the input through the composition of three operators: an imaging operator, a modeling operator, and a restriction operator. This results in a single operator that maps directly from the input data to the desired output data. We use the calculus of Fourier integral operators to develop this theory in the presence of caustics. For both DMO and AMO, we compute impulse responses in a constant-velocity model and a more complicated model in which caustics are generated. This analysis reveals errors that can be introduced by assuming, for example, a model with a constant vertical velocity-gradient when the true model is laterally heterogeneous. Data continuation uses as input a subset (common-offset, common-angle) of the available data, which introduces artifacts in the continued data. One could suppress artifacts by stacking over a neighborhood of input data (using a small range of offsets, or angles, for example).
Fluorescent Proteins Expressed in Mouse Transgenic Lines Mark Subsets of Glia, Neurons, Macrophages, and Dendritic Cells for Vital Examination

To enable vital observation of glia at the neuromuscular junction, transgenic mice were generated that express proteins of the green fluorescent protein family under control of transcriptional regulatory sequences of the human S100B gene. Terminal Schwann cells were imaged repetitively in living animals of one of the transgenic lines to show that, except for extension and retraction of short processes, the glial coverings of the adult neuromuscular synapse are stable. In other lines, subsets of Schwann cells were labeled. The distribution of label suggests that Schwann cells at individual synapses are clonally related, a finding with implications for how these cells might be sorted during postnatal development. Other labeling patterns, some present in unique lines, included astrocytes, microglia, and subsets of cerebellar Bergmann glia, spinal motor neurons, macrophages, and dendritic cells. We show that lines with labeled macrophages can be used to follow the accumulation of these cells at sites of injury.
Exploring the link between work-family conflict and job burnout among Indian police officers

Working in law enforcement can be a trying experience that can result in work-family conflict. Work-family conflict occurs when the domains of work and home spill into one another, causing strain and conflict for a person. There are four major dimensions of work-family conflict: time-based, behaviour-based, strain-based and family-based. One consequence of being exposed to the stressor of work-family conflict over time is job burnout. Job burnout has three major dimensions: emotional exhaustion, depersonalisation and a reduced sense of personal accomplishment on the job. The current study explored the association between four types of work-family conflict with the three dimensions of burnout among Indian police officers. All four types of work-family conflict were positively related to emotional burnout. Time-based, behaviour-based and family-based conflict had significant positive associations with depersonalisation burnout and with reduced sense of personal accomplishment burnout.
Academy Awards Speeches Reflect Social Status, Cinematic Roles, and Winning Expectations

An analysis of Academy Awards acceptance speeches revealed that social status is indicated through pronouns. Speeches from high status movie directors contained fewer self-references than relatively low status actors. Directors also communicated analytically compared with actors, who told stories and communicated narratively. A post hoc analysis revealed that unexpected award winners communicated more positively than those who were expected to win. The analyses emphasize the importance of replications in the social sciences and extending social and psychological phenomena to new settings.

A Machine Learning Approach to Pronoun Resolution in Spoken Dialogue

We apply a decision tree based approach to pronoun resolution in spoken dialogue. Our system deals with pronouns with NP-and non-NP-antecedents. We present a set of features designed for pronoun resolution in spoken dialogue and determine the most promising features. We evaluate the system on twenty Switchboard dialogues and show that it compares well to Byron's (2002) manually tuned system.
Retinal compensatory changes after light damage in albino mice

Purpose To investigate the anatomic and functional changes triggered by light exposure in the albino mouse retina and compare them with those observed in the albino rat. Methods BALB/c albino mice were exposed to 3,000 lx of white light during 24 h and their retinas analyzed from 1 to 180 days after light exposure (ALE). Left pupil mydriasis was induced with topical atropine. Retinal function was analyzed by electroretinographic (ERG) recording. To assess retinal degeneration, hematoxylin and eosin staining, the TdT-mediated dUTP nick-end labeling (TUNEL) technique, and quantitative immunohistofluorescence for synaptophysin and protein kinase Cα (PKCα) were used in cross sections. Intravenous injection of horseradish peroxidase and Fluoro-Gold™ tracing were used in whole-mounted retinas to study the retinal vasculature and the retinal ganglion cell (RGC) population, respectively. Results Light exposure caused apoptotic photoreceptor death in the central retina. This death was more severe in the dorsal than in the ventral retina, sparing the periphery. Neither retinal vascular leakage nor retinal ganglion cell death was observed ALE. The electroretinographic a-wave was permanently impaired, while the b-wave decreased but recovered gradually by 180 days ALE. The scotopic threshold responses, associated with the inner retinal function, diminished at first but recovered completely by 14 days ALE. This functional recovery was concomitant with the upregulation of protein kinase Cα and synaptophysin. Similar results were obtained in both eyes, irrespective of mydriasis. Conclusions In albino mice, light exposure induces substantial retinal damage, but the surviving photoreceptors, together with compensatory morphological/molecular changes, allow an important restoration of the retinal function.
The Invisible 1%: A Comparison of Attaining Stepping Stones Toward College Between Military and Civilian Children

ABSTRACT This study examined the differences between U.S. civilian and military children in their attainment of milestones toward college during a period of burgeoning military deployment (2002–2004). In spite of this intensive deployment, the process of attainment of milestones toward college among military children from Grade 10 to Grade 12 was remarkably similar to that of civilian children.
Empty Creditors and Strong Shareholders: The Real Effects of Credit Risk Trading

Credit derivatives give creditors the possibility to transfer debt cash flow rights to other market participants while retaining control rights. We use the market for credit default swaps (CDSs) as a laboratory to show that the real effects of such debt unbundling crucially hinge on shareholder bargaining power. We find that creditors buy more CDS protection when facing strong shareholders to secure themselves a valuable outside option in distressed renegotiations. After the start of CDS trading, the distance-to-default, investment, and market value of firms with powerful shareholders drop by 7.9%, 7%, and 8.8% compared to other firms.
Compressive sensor networks : fundamental limits and algorithms

Compressed sensing is a non-adaptive compression method that takes advantage of natural sparsity at the input and is fast gaining relevance to both researchers and engineers for its universality and applicability. First developed by Candes et al., the subject has seen a surge of high-quality results both in its theory and applications. This thesis extends compressed sensing ideas to sensor networks and other bandwidth-constrained communication systems. In particular, we explore the limits of performance of compressive sensor networks in relation to fundamental operations such as quantization and parameter estimation. Since compressed sensing is originally formulated as a real-valued problem, quantization of the measurements is a very natural extension. Although several researchers have proposed modified reconstruction methods that mitigate quantization noise for a fixed quantizer, the optimal design of such quantizers is still unknown. We propose to find the optimal quantizer in terms of minimizing quantization error by using recent results in functional scalar quantization. The best quantizer in this case is not the optimal design for the measurements themselves but rather is reweighted by a factor we call the sensitivity. Numerical results demonstrate a constant-factor improvement in the fixed-rate case. Parameter estimation is an important goal of many sensing systems since users often care about some function of the data rather than the data itself. Thus, it is of interest to see how efficiently nodes using compressed sensing can estimate a parameter, and if the measurements scalings can be less restrictive than the bounds in the literature. We explore this problem for time difference and angle of arrival, two common methods for source geolocation. We first derive Cramer-Rao lower bounds for both parameters and show that a practical block-OMP estimator can be relatively efficient for signal reconstruction. However, there is a large gap between theory and practice for time difference or angle of arrival estimation, which demonstrates the CRB to be an optimistic lower bound for nonlinear estimation. We also find scaling laws for time difference estimation in the discrete case. This is strongly related to partial support recovery, and we derive some new sufficient conditions that show a 3 very simple reconstruction algorithm can achieve substantially better scalings than full support recovery suggests is possible.

Fitness to Stand Trial and Disability Discrimination: An International Critique of Australia

In Noble v Australia (2016) the United Nations Committee on the Rights of Persons with Disabilities determined that Australia was in violation of a series of its obligations under the United Nations Convention on the Rights of Persons with Disabilities. The decision was a response to a communication brought by an Indigenous man, Marlon Noble, who had been found unfit to stand trial, had not had the opportunity to plead not guilty, and had been detained in a prison for over a decade. This article reviews the reasoning in the decision, the subsequent response by the Australian government and an inquiry into Western Australia's fitness to stand trial legislation. It argues that reform is urgently required in jurisdictions that fail to accord procedural fairness and suitable assistance to persons whose disabilities may preclude their meaningful participation in the criminal justice system.
Quantitative Physicochemical Analysis of Acid‐Base Balance and Clinical Utility of Anion Gap and Strong Ion Gap in 806 Neonatal Calves with Diarrhea

Background Acid‐base abnormalities in neonatal diarrheic calves can be assessed by using the Henderson‐Hasselbalch equation or the simplified strong ion approach which use the anion gap (AG) or the strong ion gap (SIG) to quantify the concentration of unmeasured strong anions such as d‐lactate. Hypothesis/Objectives To determine and compare the clinical utility of AG and SIG in quantifying the unmeasured strong anion charge in neonatal diarrheic calves, and to examine the associations between biochemical findings and acid‐base variables by using the simplified strong ion approach. We hypothesized that the SIG provides a more accurate prediction of unmeasured strong anions than the AG. Animals Eight hundred and six neonatal diarrheic calves admitted to a veterinary teaching hospital. Methods Retrospective study utilizing clinicopathologic findings extracted from medical records. Results Hyperphosphatemia was an important predictor of venous blood pH. Serum inorganic phosphorus and plasma d‐lactate concentrations accounted for 58% of the variation in venous blood pH and 77% of the variation in AG and SIG. Plasma d‐ and total lactate concentrations were slightly better correlated with SIG (r s = −0.69; −0.78) than to AG (r s = 0.63; 0.74). Conclusions and Clinical Importance Strong ion gap is slightly better at quantifying the unmeasured strong anion concentration in neonatal diarrheic calves than AG. Phosphorus concentrations should be included as part of the calculation of A tot when applying the simplified strong ion approach to acid‐base balance to critically ill animals with hyperphosphatemia.
Predicting the future relevance of research institutions - The winning solution of the KDD Cup 2016

The world's collective knowledge is evolving through research and new scientific discoveries. It is becoming increasingly difficult to objectively rank the impact research institutes have on global advancements. However, since the funding, governmental support, staff and students quality all mirror the projected quality of the institution, it becomes essential to measure the affiliation's rating in a transparent and widely accepted way. We propose and investigate several methods to rank affiliations based on the number of their accepted papers at future academic conferences. We carry out our investigation using publicly available datasets such as the Microsoft Academic Graph, a heterogeneous graph which contains various information about academic papers. We analyze several models, starting with a simple probabilities-based method and then gradually expand our training dataset, engineer many more features and use mixed models and gradient boosted decision trees models to improve our predictions.
The prerequisites of prosocial behavior in human ontogeny

Understanding the development of moral attitudes toward unrelated individuals from different social groups may provide insights into the role of biological and cultural factors in prosocial behavior. Children (3–11 years old, N=80) were presented with moral dilemmas describing a conflict of interests between a con-specific (human) and another species (animals or aliens). Participants were asked to evaluate the behavior of a human in terms of ‘good’ and ‘bad’, and to choose whom they would help: a human aggressor who benefits at the expense of a victim in vital need, or the victim. Results showed that the older children preferred to help non-human victims significantly more often than the younger children. The evaluation of human actions was related to the proportion of such preferences. These findings are discussed from the perspectives of kin selection theory, group selection theory and the system-evolutionary approach. The implications of the study for moral education are suggested.
Green fluorescent protein variants as ratiometric dual emission pH sensors. 1. Structural characterization and preliminary application.

Novel dual emission, pH-sensitive variants of the green fluorescent protein (GFP) have been constructed and are suitable for ratiometric emission measurements in vivo. This new class of GFPs, termed deGPFs, results from substitution of wild-type residue 65 with threonine and residues 148 and/or 203 with cysteine. deGFPs display pK(a) values ranging from 6.8 to 8.0 and emission that switches from a green form (lambda(max) approximately 515 nm) to a blue form (lambda(max) approximately 460 nm) with acidifying pH. In this report we analyze in most detail the deGFP1 variant (S65T/H148G/T203C, pK(a) approximately 8.0) and the deGFP4 variant (S65T/C48S/H148C/T203C, pK(a) approximately 7.3). In the following paper [McAnaney, T. B. , Park, E. S. , Hanson, G. T. , Remington, S. J., and Boxer, S. G. (2002) Biochemistry 41, 15489-15494], data obtained by ultrafast fluorescence upconversion spectroscopy can be described by a kinetic model that includes an excited-state proton-transfer pathway at high pH but not at low pH. Crystal structure analyses of deGFP1 at high-pH and low-pH conformations were performed to elucidate the basis for the dual emission characteristics. At low pH the structure does not contain a hydrogen bond network that would support rapid transfer of a proton from the excited state of the neutral chromophore to a suitable acceptor; hence blue emission is observed. At high pH, backbone rearrangements induced by changes in the associated hydrogen bond network permit excited-state proton transfer from the excited state of the neutral chromophore to the bulk solvent via Ser147 and bound water molecules, resulting in green emission from the anionic chromophore. Comparative analysis suggests that the basis for dual emission is elimination of the wild-type proton-transfer network by the S65T substitution, a general reduction in hydrogen-bonding opportunities, and a concomitant increase in the hydrophobic nature of the chromophore environment resulting from the cysteine substitutions. We evaluated the suitability of the deGFP4 variant for intracellular pH measurements in mammalian cells by transient expression in PS120 fibroblasts. The responses of deGFP4 and a commercially available pH-sensitive dye, SNARF-1, to changes in pH were compared in the same cells. Results show that the dynamic range of the emission ratio change is comparable between the two pH sensors over the range examined. Two-photon excitation was found to elicit a better deGFP4 fluorescent signal above cellular autofluorescence when compared to conventional confocal microscopy. Given their favorable optical characteristics, suitable pK(a)'s for the physiological pH range, and suitability for ratiometric measurements, dual emission GFPs should make excellent probes for studying pH in vivo.
Developing New Locality Results for the Prüfer Code using a Remarkable Linear-Time Decoding Algorithm

The Prufer Code is a bijection between the $n^{n-2}$ trees on the vertex set $[1,n]$ and the $n^{n-2}$ strings in the set $[1,n]^{n-2}$ (known as Prufer strings of order $n$). Efficient linear-time algorithms for decoding (i.e., converting string to tree) and encoding (i.e., converting tree to string) are well-known. In this paper, we examine an improved decoding algorithm (due to Cho et al. ) that scans the elements of the Prufer string in reverse order, rather than in the usual forward direction. We show that the algorithm runs in linear time without requiring additional data strutures or sorting routines, and is an 'online' algorithm — every time a new string element is read, the algorithm can correctly output an additional tree edge without any knowledge of the future composition of the string. This new decoding algorithm allows us to derive results concerning the 'locality' properties of the Prufer Code (i.e., the effect of making small changes to a Prufer string on the structure of the corresponding tree). First, we show that mutating the $\mu$th element of a Prufer string (of any order) causes at most $\mu + 1$ edge-changes in the corresponding tree. We also show that randomly mutating the first element of a random Prufer string of order $n$ causes two edge-changes in the corresponding tree with probability $2(n-3)/n(n-1)$, and one edge-change otherwise. Then, based on computer-aided enumerations, we make three conjectures concerning the locality properties of the Prufer Code, including a formula for the probability that a random mutation to the $\mu$th element of a random Prufer string of order $n$ causes exactly one edge-change in the corresponding tree. We show that if this formula is correct, then the probability that a random mutation to a random Prufer string of order $n$ causes exactly one edge-change in the corresponding tree is asymptotically equal to one-third, as $n$ tends to infinity.
