Predictive properties and minimaxity of Bayesian predictive synthesis

We examine and compare the predictive properties of classes of ensemble methods, including the recently developed Bayesian predictive synthesis (BPS). We develop a novel strategy based on stochastic processes, where the predictive processes are expressed as stochastic differential equations, evaluated using It\^{o}'s lemma. Using this strategy, we identify two main classes of ensemble methods: linear combination and non-linear synthesis, and show that a subclass of BPS is the latter. With regard to expected squared forecast error, we identify the conditions and mechanism for which non-linear synthesis improves over linear combinations; conditions that are commonly met in real world applications. We further show that a specific form of non-linear BPS (as in McAlinn and West, 2019) produces exact minimax predictive distributions for Kullback-Leibler risk and, under certain conditions, quadratic risk. A finite sample simulation study is presented to illustrate our results.
Salmonella control in poultry flocks and its public health impact

Abstract An increase in confirmed human salmonellosis cases in the EU after 2014 triggered investigation of contributory factors and control options in poultry production. Reconsideration of the five current target serovars for breeding hens showed that there is justification for retaining Salmonella Enteritidis, Salmonella Typhimurium (including monophasic variants) and Salmonella Infantis, while Salmonella Virchow and Salmonella Hadar could be replaced by Salmonella Kentucky and either Salmonella Heidelberg, Salmonella Thompson or a variable serovar in national prevalence targets. However, a target that incorporates all serovars is expected to be more effective as the most relevant serovars in breeding flocks vary between Member State (MS) and over time. Achievement of a 1% target for the current target serovars in laying hen flocks is estimated to be reduced by 254,400 CrI95[98,540; 602,700] compared to the situation in 2016. This translates to a reduction of 53.4% CrI95[39.1; 65.7] considering the layer‐associated human salmonellosis true cases and 6.2% considering the overall human salmonellosis true cases in the 23 MSs included in attribution modelling. A review of risk factors for Salmonella in laying hens revealed that overall evidence points to a lower occurrence in non‐cage compared to cage systems. A conclusion on the effect of outdoor access or impact of the shift from conventional to enriched cages could not be reached. A similar review for broiler chickens concluded that the evidence that outdoor access affects the occurrence of Salmonella is inconclusive. There is conclusive evidence that an increased stocking density, larger farms and stress result in increased occurrence, persistence and spread of Salmonella in laying hen flocks. Based on scientific evidence, an impact of Salmonella control programmes, apart from general hygiene procedures, on the prevalence of Campylobacter in broiler flocks at the holding and on broiler meat at the end of the slaughter process is not expected.

THE CHARACTERIZATION OF PARTICULATE MOTOR VEHICLE EMISSIONS BY ELECTROSTATIC MEASUREMENT TECHNIQUES

Electrostatic Measurement Techniques have been applied to the characterization of submicron aerosols since 1966. Initially designed for laboratory and ambient measurement tasks only this method has been more or less successfully applied also for emission aerosol characterization, encountering numerous problems. Main issue is the dilution problem, making the use of this method rather complicated and requiring a high level of knowledge to avoid erroneous results. It will be shown, that a rather simple redesign of the method can solve most of the intrinsic problems connected with the characterization of highly concentrated particles suspended in a reactive carrier gas at prohibitive temperature and pressure levels. A few selected examples are presented, outlining the broad spectrum of applications. Some consequences of the findings leading to questions of environmental management policies are shortly discussed.
Clinical diagnosis and oral propranolol curative effect analysis of infant subglottic hemangioma

Objective: To investigate the diagnosis of subglottic hemangioma in infants by bronchoscopy combined with laryngeal imaging and the therapeutic effect of oral administration of propranolol. Methods: A retrospective analysis was performed for 16 pediatric patients who were admitted to the Children’s Medical Center of Hunan People’s Hospital from November 2012 to May 2018 and were diagnosed with subglottic hemangioma. The diagnosis was confirmed by bronchoscopy combined with laryngeal enhanced CT or MRI. Clinical data was extracted from the medical records and further ascertained by physician interviews. Results: All clinical cases had respiratory symptoms, mainly showed as laryngeal stridor, coughing, and wheezing. Bronchoscopy indicated limited smooth and soft subglottic tumors showing dark red or purple, which resulted in local lumen stenosis. After taking propranolol orally for 24-48 hours, the symptoms of laryngeal wheezing or obstruction were alleviated, and 3 children with laryngeal obstruction were successfully removed from mechanical ventilation after 3-5 days. One case of hemoptysis with lower right basal stem hemangioma was given an interventional closure. After 6 months of oral Propranolol, 6 cases of tumors had completely faded, 8 cases of tumors had significantly reduced. In 12 cases, the treatment was stopped after 6 to 12 months when the obstructive symptoms improved, and the obstructing mass in the subglottis was less than 10% of the diameter; 11 cases in this group had no any evidence of recurrence, but 1 case had a slight increase in the past drug withdrawal after the 6 month review. Conclusions: Oral propranolol has definite curative effects, less side effects, and less trauma; therefore, it could be used as the main treatment for infantile subglottic hemangioma.
Constructive matheuristic algorithms for solving the multi-depot vehicle scheduling problem for public transportation

This paper considers the Vehicle Scheduling Problem of public transportation by considering Multi-depots (MDVSP). We propose three hybrid constructive algorithms combining heuristic and exact methods. The proposed approaches are validated by using 90 benchmark instances, having between two and five depots, and between 100 and 500 trips. Also, the efficiency of the algorithms has tested on real instances obtained from the Mass Transit System of the Centro Occidente de Centro Metropolitana de Colombia (AMCO), whose operation consists of about 5000 trips daily
Student clustering in an ER program

This study examined the gains in student affect, vocabulary, and reading fluency for 110 university students in an extensive reading program in Japan. It was important to measure all of these dimensions within a single study and a single teaching methodology, so gains could be appropriately compared against each other. The adopted teaching methodology was a communicative one which stressed a number of in-class activities, with out-of-class reading. Students were measured over the course of a semester, and paired-sample t-tests were conducted using preand post-test scores on six variables. Results indicated that affect increased a great deal, while fluency increased minimally, and vocabulary did not increase at all. Students were also clustered into two groups, higher-level and lower-level, to determine if they differed at all in their learning rates. Paired sample t-tests indicated that the lower-level students gained more in terms of fluency than the higher-level students.
Restricted Tolls for Network Routing Games

We study tolls for network routing games in which players selfishly choose routes through a network that minimise their own cost. It is a well known fact that such behaviour can lead to suboptimal solutions. Tolls can incite players to behave in such a way that the system as a whole is less congested. We briefly review earlier literature on tolling schemes and present some new insights and results based thereon. The field of interest is quite broad in some sense: many different networks and types of players are considered. The networks may be as simple as a set of parallel arcs, but for some applications may be as general as any multicommodity graph. We consider both non-atomic and atomic (weighted and unweighted) players, who may be homogeneous or heterogeneous with regard to their sensitivity to taxation. The class of problems we focus on in this thesis is that of restricted toll problems, in which we restrict the amount of toll that can be imposed on every arc. Our results can be categorised under characterisations, hardness proofs and polynomial time algorithms. We present conditions for several routing games under which a given flow is inducible by (restricted) tolls. These are often key to deriving algorithms which compute optimal tolls to the respective routing games. The most notable hardness result applies to non-atomic, heterogeneous players on single-commodity networks. We show that it is NP-hard to compute optimal restricted tolls in this case. For atomic players, we present two characterisations of flows inducible by restricted tolls and a polynomial time algorithm for the restricted toll problem on parallel arcs with homogeneous players. We solve the taxing subnetworks problem on parallel arc networks for both heterogeneous atomic and heterogeneous non-atomic players.

Frequency and Duration of Daily Smartphone Usage in Relation to Personality Traits

Objectives: Daily life behaviour can be studied by smart mobile devices. The current study investigated associations between personality traits and smartphone usage in daily routine. Methods: 526 participants used the Track Your Daily Routine smartphone app (TYDR) for 48 days, on average (SD = 63.2, range 2 to 304). The Big Five Inventory 2 (BFI-2) was deployed to measure personality traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness). We analyzed associations between personality traits and two indicators of smartphone usage: number of wakeups per day and session duration. Results: Participants reached for a smartphone more frequently during weekdays with shorter duration of usage compared to weekends. Younger people used their smartphones more often but with a shorter duration than older people. Female participants spent more time using smartphone per session than male participants. Extraversion and neuroticism were associated with more frequent checking of the phone per day while conscientiousness was associated with a shorter duration of the session per day. Conclusions: Frequency and duration of daily smartphone usage is associated with personality traits and participants demographics (age, gender). Implications for future research are discussed.
DETECTION OF POLLEN FLOW IN THE SEEDLING SEED ORCHARD OF Acacia mangium USING DNA MARKER

Pollen pattern dispersal in seedling seed orchard (SSO) is an essential part of a tree-improvement program. Two SSOs of Acacia mangium in South Kalimantan and South Sumatra that represent similar resources in different environments were used in this study. Genotypes of all trees and seeds from a subset of 10 mother trees in each orchard were determined for 12 microsatellite loci, and parentage analysis was carried out. The results shows that the pollen dispersal pattern in both SSOs decrease with distance from mother tree. Patterns of pollen dispersal, dispersal distance and cumulative frequency of pollen dispersal distance were similar in both SSOs. Random pollen dispersal were found in both SSOs. About 80% of all crosses were found within a 40-m distance range with the most frequent pollination distance between mother tree and male male parents was 0-10 m. No self-pollinated seed was detected. Application of all these aspects found in this study such as random pollen dispersal and the effective pollen dispersal distance can be useful for establishing seedling seed orchard, clonal seed orchard and in other tree improvement activities of A. mangium .
Corneal Stem Cells as a Source of Regenerative Cell-Based Therapy

In the past few years, intensive research has focused on corneal stem cells as an unlimited source for cell-based therapy in regenerative ophthalmology. Today, it is known that the cornea has at least two types of stem cells: limbal epithelial stem cells (LESCs) and corneal stromal stem cells (CSSCs). LESCs are used for regeneration of corneal surface, while CSSCs are used for regeneration of corneal stroma. Until now, various approaches and methods for isolation of LESCs and CSSCs and their successful transplantation have been described and tested in several preclinical studies and clinical trials. This review describes in detail phenotypic characteristics of LESCs and CSSCs and discusses their therapeutic potential in corneal regeneration. Since efficient and safe corneal stem cell-based therapy is still a challenging issue that requires continuous cooperation between researchers, clinicians, and patients, this review addresses the important limitations and suggests possible strategies for improvement of corneal stem cell-based therapy.
Secure Data Deduplication in Hadoop Distributed File Storage System

– Big data is a collection of large amount of data that contains duplicated items collected from various sources. To detect duplicated data from big data is a serious issue. In this paper secure deduplication mechanism has been proposed for big data storage. In proposed work, fixed size chunking mechanism is used to create chunks of a large file and SHA-2 algorithm is used to generate secure hashes of chunks and on the basis of these hashes deduplication has been done. The proposed mechanism has been implemented using Hadoop and analyzed using chunk time and hash time.

Oxidative priming of neutrophils by interferon‐y

Priming of neutrophil (PMN) oxidative responses is an integral component of host defense and inflammation and may contribute to cell‐mediated tissue injury. The characteristics and mechanisms of interferon‐ γ (EFN‐γ)‐induced oxidative priming of PMNs were explored in vitro. Following pretreatment of human PMNs with recombinant IFN‐γ, superoxide anion release was selectively primed toward the receptor‐initiated stimulants f‐Met‐Leu‐Phe (fMLP) and C5a but not toward the transduction‐mediated stimulants phorbol myristate acetate and A23187, a calcium ionophore. IFN‐γ also induced priming toward the stimulant NaF, a direct activator of guanine nucleotide regulatory proteins. Priming was not associated with changes in fMLP surface receptor expression or degranulation. Priming was dependent on de novo mRNA and protein synthesis. The immuno‐ regulatory lymphokine IFN‐y primes PMN oxidative responses, apparently via production of proteins that are involved in the early postreceptor transductional pathways of oxidative metabolism.
Abstractive News Summarization via Copying and Transforming

Automatic Abstractive summarization in the news domain often relies on the use of a Pointer-Generator architecture, which favor the use of long extracts from the article. We propose a new architecture, Copy and Trans-form (CaT), that produces more abstractive summaries. We build a new coverage mechanism, keyword coverage , that encourages the decoder at test-time to use pre-deﬁned key-words. We train our CaT model with key-word coverage on two stylistically different datasets, and obtain state-of-the-art results on both datasets (+0.3 ROUGE-1 on CNNDM, +4.1 ROUGE-1 on Newsroom). We show human judges prefer our summaries over previous state-of-the-art, but still prefer human-written summaries. Our system can summarize articles in two styles, bullet-point and long-sentence, and a list of desired keywords can be provided to customize the summary.
Prevalence of Vancomycin Resistant Enterococci (VRE) in Catheter Associated Urinary Tract Infections(CAUTI) with special reference to biofilm formation

Introduction: Enterococci have been recognized as an important cause of hospital-acquired infections. They are currently the second most common organisms recovered from nosocomial urinary tract infection. Emergence of Vancomycin resistance has been a threat in the hospital settings. Biofilm formation is also an important virulence factor contributing to drug resistance. Aim: To know the prevalence of VRE in device infections CAUTI and role of biofilm formation in the associations of CAUTI. Materials and Methods: Total 100 Catheter-Associated Urinary Tract Infection (CAUTI) cases were included. Controls comprised of 50 cases of UTI but non-catheterized. Bacteriological identification and susceptilibity testing were done as per standard protocol. Results: Overall culture positivity in CAUTI was 32%. Enterococci (40.62%) were the predominant pathogens followed by Esch.coli (37.50%). VRE prevalence in current study was 18.75%. Strong biofilms were mainly produced by resistant isolates(30.76%). Biofilm formation by VRE was statistically significant (p value= 0.01124). VRE infection was also more common in CAUTI (p value= 0.000019). Conclusion: VRE detection and its control entail an aggressive approach which involves strict adherence to standard infection control practices by the hospital personnel. Role of the Microbiology Laboratory plays important role in the Detection, Reporting and Control of VRE. Collaboration between the laboratory and the infection-control program will definitely play an important
Challenges to Be Faced on Flip-chip Bonder to Achieve Precision Requirements in Different Environments

Among different technologies to assemble and interconnect microelectronic chips together, flip-chip technology appears promising. Its main advantages are the potentially very high density interconnect and the much shorter interconnection paths. We observe an everlasting search for the reduction of the dimensions and the power consumption of electronic systems, driven by all the mobile applications. In the meanwhile, the communication speed and storage capacities need to be continuously improved. Moreover, the suppression of wires presents many assets, as reduction of electrical inductance and resistance while using less noble materials. For all these reasons, flip-chip technology is becoming more and more interesting. Many different kinds of processes can be done on a flip-chip bonder, including chip to chip (C2C) and chip to wafer (C2W), thermocompression, UV-curing, gluing and 3D stacking. Applications are also various, as for example assembly of medical electronics, photonics and optoelectronics devices as well as MEMS or sensors. The general trend to reduce the size of components as described above leads to reduce the pitches between electrical interconnections. Consequently, the post-bonding precision becomes crucial and is getting higher and higher. It generates many challenges in the design of chip, in the elaboration of processes and in the conception of flip-chip bonders. Through several partnerships and equipment installations at leading research institutes around the world, some technological advancement has emerged, including: CEA-LETI, Grenoble, France has presented successful die-to-wafer bonding using 4 μm diameter Au-coated microtubes at 10 μm pitch inserted into pads, as well as a molecular attachment bonding method developed within the Proceed project, Sematech USA and IMEC Belgium have each developed a hybrid collective bonding scheme where accurate die-to-wafer initial bonding is followed by gang bonding to finalize many bonds in parallel, IME Singapore has developed several solder compositions and methods to create reflow bonding process options. Each process has its own assets but also its own constraints that equipment manufacturers have to take into account in the design of bonders. This paper will explore some challenges to be faced by flip-chip bonders, depending on the applications to be achieved and the environment, R&D or production.
