Parental Arrest , Incarceration and the Outcomes of Their Children

Parental arrest and incarceration represents a profound and traumatic experience for almost 3 million children in the U.S. and scholars in sociology and criminology consistently nd negative impacts of parental incarceration on children across a range of academic and behavioral outcomes. Unfortunately, the challenge of disentangling parental incarceration from other parenting attributes has limited causal inference in this literature. The research presented here provides compelling evidence that parental arrest coincides with negative outcomes for children, but that the incarceration of a parent may bene t the child. Results suggest that incarceration removes negative role models and leads to changes in a child’s home environment. ∗stephen.billings@colorado.edu, Leeds School of Business, University of Colorado Acknowledgements: I thank Eric Chyn, Jennifer Doleac, Rick Mans eld, Terra McKinnish, Erik Plug and Je rey Zax as well as participants at the University of Virginia Public Economics Workshop, 2017 University of Lund-SFI Labor/Health Economics workshop.

Feature Extraction for Load Identification Using Long-Term Operating Waveforms

This paper introduces a novel finite-state-machine (FSM) representation of long-term load operating waveforms for feature extraction and load identification. An operating waveform is first converted into a quantized sequence of states. Each state is assigned with 2-D numerical values: root mean square (RMS) current values and staying time values. A set of elemental states and events are defined to reduce the number of states and extract numerical features to represent electric loads for classification and identification. Three major categories of repeating patterns in waveforms that correspond to repeating operating actions are summarized and identification methods are proposed for each such category. Test results using a large dataset of real-world waveforms show that the different appliances have distinct ranges of features extracted from the proposed FSM representation, and thus can be identified with high accuracy.
PCR Use of Highly Conserved DNA Regions for Identification of Sinorhizobium meliloti

ABSTRACT A PCR identification method in which four primers that recognize homologous conserved regions in the Sinorhizobium melilotigenome are used was developed and tested. The regions used for identification were the nodbox 4 locus, which is located in one of the symbiotic megaplasmids, and the mucR gene, which is located in the chromosome. The new method was used to establish a collection ofS. meliloti strains from polluted soils.
Differentia compositionem facit. A Slower-Paced and Reliable Parser for Latin

The Index Thomisticus Treebank is the largest available treebank for Latin; it contains Medieval Latin texts by Thomas Aquinas. After experimenting on its data with a number of dependency parsers based on different supervised machine learning techniques, we found that DeSR with a multilayer perceptron algorithm, a right-to-left transition, and a tailor-made feature model is the parser providing the highest accuracy rates. We improved the results further by using a technique that combines the output parses of DeSR with those provided by other parsers, outperforming the previous state of the art in parsing the Index Thomisticus Treebank. The key idea behind such improvement is to ensure a sufficient diversity and accuracy of the outputs to be combined; for this reason, we performed an in-depth evaluation of the results provided by the different parsers that we combined. Finally, we assessed that, although the general architecture of the parser is portable to Classical Latin, yet the model trained on Medieval Latin is inadequate for such purpose.
Use of Moraxella catarrhalis Lipooligosaccharide Mutants To Identify Specific Oligosaccharide Epitopes Recognized by Human Serum Antibodies

ABSTRACT Moraxella catarrhalis is a causative agent of otitis media in children and lower respiratory tract infections in adults suffering from chronic obstructive pulmonary disease (COPD). This strict human pathogen continues to be a significant cause of disease in this broad spectrum of patients because there is no available vaccine. Although numerous putative vaccine antigens have been described, little is known about the human immune response to M. catarrhalis infection in vivo. Human serum antibodies are directed at a number of surface proteins, and lipooligosaccharides (LOS) and detoxified LOS may be an effective immunogen in mice. In this study, we used a specific LOS-based enzyme-linked immunosorbent assay (ELISA), containing the three major M. catarrhalis serotypes together with a complete series of truncated LOS mutants, to detect the development of new antibodies to specific regions of the oligosaccharide molecule. We compared serum samples from COPD patients who had recently cleared an M. catarrhalis infection to serum samples collected prior to their infection. Variability in the antibody response to LOS was observed, as some patients developed serotype-specific antibodies, others developed antibodies to the LOS of each serotype, others developed broadly cross-reactive antibodies, and some did not develop new antibodies. These newly developed human antibodies are directed at both side chains and core structures in the LOS molecule. This LOS-based ELISA can be used to dissect the human antibody response to both internal and external carbohydrate epitopes, thus providing a better understanding of the humoral immune response to M. catarrhalis LOS epitopes developed during natural infection.
Towards an ontology for global software development

As planning an R&D project named ORIGIN addressing global software development (GSD) foundations, the authors soon became aware of the need for all the participants to share the same vision of GSD projects. The authors therefore reached the conclusion that one of the first steps should be to set up a shared and consistent GSD project-related vocabulary, since this would help to improve communication between the five companies involved in ORIGIN. After analysing existing GSD initiatives, the authors discovered that none of them really satisfied our specific needs. As a consequence, they decided to develop a new ontology, which was named O-GSD. This paper describes not only how the ontology was developed -including the reasons which led us to include each term in O-GSD- but also its usage in real contexts -what allowed us to extract some insights to refine and validate the ontology. The main contribution of this paper is the O-GSD ontology which is used and to be used in real GSD projects with the aim of helping project managers to better describe their particular GSD projects.
Delay-dependent Robust Resilient H ∞ Control for Uncertain Singular Time-delay Systems

In this paper, the delay-dependent robust resilient H∞ control is investigated for singular time-delay systems with norm-bounded parameter uncertainty. First, a new delaydependent bounded real lemma (BRL) for the nominal singular time-delay system is established. Then the problem of robust resilient H∞ control is solved via a resilient controller with respect to additive and multiplicative controller gain variations, which guarantees the closed-loop system to be regular, impulse free, internally stable and satisfies an H∞ norm condition for all admissible uncertainties. The explicit expression for the desired robust resilient H∞ controller is deigned by using the LMIs and the cone complementarity linearization iterative algorithm. Index Terms — uncertain singular time-delay systems, resilient H∞ control, delay-dependent criteria, linear matrix inequality(LMI).
A high bandwidth power scaleable sub-sampling 10-bit pipelined ADC with embedded sample and hold

A pipelined ADC architecture for use in sub-sampled systems which has its power scaleable with down sampled bandwidth is presented. Using a technique developed to eliminate the front end sample and hold, a power savings of >20% is achieved compared to a previous design. A technique to improve the settling behavior of Rapid Power on Opamps is also presented. Measured results in 1.8V 0.18 mum CMOS verify the removal of the front end sample and hold does not cause gross MSB errors for input frequencies higher than 267 MHz. With fs=50 MS/s, for fin=79 MHz the SNDR is 51.5 dB, and with fs=4.55 MS/s for fin=267 MHz the SNDR is 52.2 dB.
Higher Risk of Failure of Methicillin-resistant Staphylococcus aureus Prosthetic Joint Infections

We determined the effect of methicillin resistance on the outcome of patients with Staphylococcus aureus prosthetic joint infections. From January 1995 to December 2004, 33% of 137 episodes of prosthetic joint infections were the result of S. aureus (in monomicrobial or polymicrobial cultures). Thirty-three (24%) episodes among 31 patients were the result of methicillin-susceptible S. aureus and 12 (9%) episodes among 12 patients were the result of methicillin-resistant S. aureus. Overall treatment failure rate was 38%. Patients with methicillin-susceptible S. aureus or methicillin-resistant S. aureus prosthetic joint infections did not differ in age, gender, comorbidities, joint age, prior surgical procedures performed on the affected joint, number of postsurgical medical complications, or duration of intravenous antimicrobial therapy. Patients with methicillin-resistant S. aureus prosthetic joint infection had longer hospital durations (median, 15 versus 10 days). Methicillin-resistant S. aureus in periprosthetic tissue culture resulted in a higher risk of treatment failure (hazard ratio, 9.2; 95% confidence interval, 2.40-35.46) than methicillin-susceptible S. aureus when controlling for joint location (total knee arthroplasty versus total hip arthroplasty [hazard ratio, 5.8; 95% confidence interval, 1.52-22.19]) and removal of hardware (hazard ratio, 0.24; 95% confidence interval, 0.077-0.75). Efforts should be made to prevent methicillin-resistant S. aureus infections of joint arthroplasties and develop new treatment modalities. Level of Evidence: Level II, retrospective prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.
Viscoelastic Testing of Coagulation.

Coagulopathy associated with trauma exists in one third of severely injured patients upon presentation to hospital. Our understanding of trauma-induced coagulopathy has increased significantly over the past decade. The cell-based theory of hemostasis has replaced the classic coagulation cascade proposed by Macfarlane in 1964 and emphasizes tissue factor (TF) as the initiator of coagulation released locally secondary to endothelial damage. Viscoelastic measurement of coagulation is being increasingly used to guide resuscitation for both rationalization of blood product use and to monitor effectiveness. The concept of damage control resuscitation is based on maximizing oxygen delivery, prevention of hypothermia, prevention of acidosis, and correction of coagulation parameters. Although bleeding is controlled, blood product resuscitation is achieved by adhering to local
The Different Functions of Gaze

Looking while talking (Li) may be used to obtain immediate feedback on the reactions of listeners; looking while listening (LL) may be used to supplement auditory information, by observing eye-movements and changes of facial expression. This function of gaze can be isolated in the situation where a subject interacts across a one-way screen, so that he can see and not be seen; he is unable to send any signals, so must look to collect information. Part of this information is about the other's timing of utterances and is used for synchronizing. This can be eliminated if the S delivers a monologue to his partner.
A novel framework for an efficient online recommendation system using constraint based web usage mining techniques

With the fleetly development of the internet, discovering useful knowledge from the World Wide Web became a censorious issue. With the huge volume of information present in the internet, user needs a help via recommendation system. From the user’s log data lot of recommender systems developed to predict the user’s next request when they view the web pages. However, each recommender system has its own advantages and drawbacks. A novel hybrid recommender system is proposed using a modified DBSCAN, modified prefix span algorithm and Genetic algorithm to mine the user’s sequential navigational patterns, and then a hybrid recommendation model is proposed. The proposed Hybrid recommender system produces better prediction accuracy than the existing single recommender systems. Testing results recommend that the hybrid system is better in predicting the next request page of the web user.
Risk of cryptorchidism among sons of horticultural workers and farmers in Denmark.

OBJECTIVES Previous studies indicate an increased risk of cryptorchidism, incomplete testicular descent, among sons of women working with pesticides. This study assessed the risk of cryptorchidism among boys of parents employed as horticultural workers and farmers using nationwide registers on occupation and cryptorchidism. METHODS The cohort consisted of >600 000 boys born in Denmark from 1980-2007 with a parent in employment during pregnancy. These boys were followed for cryptorchidism from 1980-2009 comparing risks among sons of horticultural workers and farmers with sons of parents in other occupations. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated using Cox regression adjusting for parental age, birth years, parity, and geographical region. RESULTS Sons of maternal farmers were at increased risk of cryptorchidism (157 cases; HR 1.31, 95% CI 1.12-1.53) compared to boys of mothers in other occupations (15 511 cases). Paternal occupation as farmer was unrelated to the risk among sons. Maternal occupation as a horticultural worker was associated with a non-significantly increased risk (72 cases; HR 1.20, 95% CI 0.95-1.52). A similar association was found for paternal horticultural workers. Sons of maternal farmers or horticultural workers who likely worked in the first trimester were not at increased risk of cryptorchidism. CONCLUSIONS This nationwide cohort study found a slightly increased risk of cryptorchidism in sons of maternal horticultural workers and farmers. However, subgroup analyses indicated similar findings for paternal horticultural workers, and no association for women likely working in the first trimester. The main findings should therefore be interpreted with caution.
Different types of segmental sclerosing glomerular lesions in six experimental models of proteinuria

From 133 to 615 glomeruli were examined in sections of kidneys from each of 60 animals, representing six rodent models of proteinuria. Particular attention was paid to the position of segmental lesions. Lewis rats given sheep anti‐rat glomerular basement membrane antibodies had lesions almost exclusively at the glomerulo‐tubular junction. Wistar rats on a diet of 24 per cent casein or with subtotal nephrectomy and a diet of 24 per cent soya had lesions mainly at the hilum. Wistar rats given bovine serum albumin had global lesions but virtually no segmental lesions. Wistar rats given puromycin aminonucleoside had lesions at the glomerulo‐tubular junction and global mesangial abnormalities shortly after the treatment but later developed segmental lesions at all parts of the glomerulus. Untreated BUF/Mna rats had lesions at the glomerulo‐tubular junction early in life but later had lesions at all parts of the glomerulus. Untreated NZB/NZW hybrid mice had various types of glomerulonephritis and also had lesions at the glomerulo‐tubular junction. These findings showed that (1) segmental lesions at the glomerulo‐tubular junction, or glomerular tip, occur in experimental animals, a fact not previously reported, and these tip changes are a common feature in several different models of proteinuria; (2) hilar segmental lesions are seen in conditions with hyperfiltration of protein; and (3) segmental lesions at various parts of the glomerulus are seen in some models of proteinuria and probably indicate late effects of random toxic damage to the glomerulus. Thus, there are at least three different types of segmental glomerular lesions in experimental animals—tip, hilar, and random—with different morphology and pathogenesis. It is likely that these findings can be extended to human renal diseases with segmental glomerular lesions. This will help to clarify the controversial and unsatisfactory term focal segmental glomerulosclerosis.
Certainty Grid Representation for Robot Navigation by a Bayesian Method

Summary Recent development of sensor knowledge representation by the use of a certainty grid has been extensive and shown the usefulness of the grid-based concept for robot navigation. Yet the methodology was not perfect. This paper introduces the Bayesian formula into the certainty grid representation to overcome some difficulties of ad hoc formula that has been the only way of updating the grids. The complete derivation of the proposed updating formula is given and proved to be able to accurately identify the simulated world. Also, the paper suggests two updating models: context-sensitive and context-free. Both of them were shown to be usable through simulation in real world modeling.
ON THE NUMBER OF CLIQUES AND CYCLES IN GRAPHS

We give a new recursive method to compute the number of cliques and cycles of a graph‎. ‎This method is related‎, ‎respectively to the number of disjoint cliques in the complement graph and to the sum of permanent function over all principal minors of the adjacency matrix of the graph‎. ‎In particular‎, ‎let $G$ be a graph and let $overline {G}$ be its complement‎, ‎then given the chromatic polynomial of $overline {G}$‎, ‎we give a recursive method to compute the number of cliques of $G$‎. ‎Also given the adjacency matrix $A$ of $G$ we give a recursive method to compute the number of cycles by computing the sum of permanent function of the principal minors of $A$‎. ‎In both cases we confront to a new computable parameter which is defined as the number of disjoint cliques in $G$‎.
NMR studies of protein–nucleic acid complexes: structures, solvation, dynamics and coupled protein folding

Many basic events which concern management and manipulation of genes within a cell – for instance transcription, replication and recombination – rely on specific interactions between proteins and nucleic acids. Such interactions are also essential for many house-keeping functions, like packing and unpacking of DNA in chromatin and assembly of ribosomes. Moreover, the details of protein–nucleic acid interplay is essential for understanding the action of viruses. The list of functional mechanisms in biology that rely on protein–DNA and protein–RNA interactions can be made much longer, but these examples represent some of the topics which motivated structural biologists to study complexes between proteins and nucleic acids as a first step beyond structure determinations of individual biomolecules.
Mixed Solution Strategy for MCGDM Problems Using Entropy/Cross Entropy in Interval-Valued Intuitionistic Fuzzy Environment

Although several weight determining methods have been studied for multiple criteria group decision making (MCGDM) problems under intuitionistic fuzzy environment, in the present study, besides the criteria values provided by the decision makers (DMs), we propose to also use the historical data of alternatives-criteria to compute the criteria weights. This is a reasonable thought as the past information may influence the decision makers' choice of entries in their respective alternatives-criteria decision matrices. To this aim, we introduce a novel mixed solution strategy to derive the criteria final weight vector. Initially, the alternatives-criteria decision matrices provided by the DMs are taken to involve interval-valued intuitionistic fuzzy numbers (IVIFNs). The entropy measure for IVIFNs, studied by Ye [2010a], is used to aggregate these decision matrices. We also introduce a new definition of cross entropy for IVIFNs and used it to rank the alternatives. Finally, an example is presented to illustrate the proposed approach.
A Lightweight Single-Camera Polarization Compass with Covariance Estimation

A lightweight visual compass system is presented as well as a direct method for estimating sun direction and its covariance. The optical elements of the system are described enabling estimation of sky polarization in a FOV of approx. 56° with a single standard camera sensor. Using the proposed direct method, the sun direction and its covariance matrix can be estimated based on the polarization measured in the image plane. Experiments prove the applicability of the polarization sensor and the proposed estimation method, even in difficult conditions. It is also shown that in case the sensor is not leveled, combination with an IMU allows to determine all degrees of orientation. Due to the low weight of the sensor and the low complexity of the estimation method the polarization system is well suited for MAVs which have limited payload and computational resources. Furthermore, since not just the sun direction but also its covariance is estimated an integration in a multi-sensor navigation framework is straight forward.
Genetic Predisposition to 4NQO-Induced Tongue Carcinogenesis in the Rat

Objective: This study aims to elucidate the genetic basis of predisposition to 4-nitroquinoline 1-oxide (4NQO)-induced tongue cancers (TCs). Materials and Methods: We have reported that inbred Dark-Agouti (DA) strain rats were highly susceptible to 4NQO-induced TCs, whereas Wistar/Furth (WF) rats were resistant to tongue squamous cell carcinomas induced by oral administration of 4NQO. Using size and number of the tumours as quantitative parameters, responsible host loci were analysed by an interval mapping of F2 intercross of DA and WF given carcinogenic regimen. Also, loss of heterozygosity (LOH) at these loci was analysed in tongue cancers in (DA × WF) F1. Results: We identified and mapped 5 significant quantitative trait loci (QTL), the Tongue squamous cell carcinoma 1–5 (Tscc1–5), and several other suggestive QTL that determine susceptibility to 4NQO-induced TC. Study of TCs induced in (DA × WF)F1 rats revealed a high frequency of LOH in the chromosomal regions of Tscc2, 3, and 4 and also of suggestive QTL on chromosomes 5 and 6. The fact that LOH was found only in larger TCs indicates that LOH occurred in the process of tumour progression. In most LOH, the allele of the resistant WF strain was lost, suggesting that these loci may encode tumour suppressor genes. In larger TCs, in addition to LOH, point mutations and the methylation of possible candidate genes were accumulated. Conclusion: These observations indicate that the 4NQO-induced TC in the rat is a multifactorial disease of a polygenic trait. This model will be useful to understand the complicated genetic basis of predisposition to oral cancers.
