description: Rising carbon dioxide emissions in South Asia are a long-run challenge. Over the last two decades, population aging, and urbanization have also been rising, further stimulating carbon dioxide emissions. Meanwhile, institutions are increasingly involved in efforts to mitigate environmental degradation. The extent to which these factors affect carbon emissions is not fully understood, particularly within South Asia. The purpose of this study is to evaluate the impact of population aging, urbanization, and the institutional quality on per capita carbon emissions in South Asia from 1996 to 2019 based on theoretical background and empirical analysis. The results of the study come through CS-ARDL uncovered that population aging and urbanization have both induced carbon emissions in Bangladesh, India, Pakistan, and Sri Lanka. Institutional quality, however, has reduced carbon emissions across the region. Furthermore, we applied CCE-MG as a robust panel estimation technique to verify our results.

Publisher: name: Rutgers University
Year: 1991

description: We prove that constant depth circuits of size $NPOLYLOG$ over the basis AND, OR, PARITY are no more powerful than circuits of this size with depth four. Similar techniques are used to obtain several other depth reduction theorems; in particular, we show every set in AC$^O$ can be recognized by a family of depth-three threshold circuits of size $NPOLYLOG$. The size bound $NPOLYLOG$ is optimal when considering depth reduction over AND, OR, and PARITY. Most of our results hold both for the uniform and the nonuniform case.

Un modello di misura per l'analisi della disoccupazione di lunga durata

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In recent years, specifically in western European countries, it has been observed a notable increase in the number of people showing long duration  of job search spells, and this aspect seems to concern mostly some specific groups of the population. Significantly, it has become very common to report besides the unemployment rate the level of long-term unemployment as an important index on the situation of labour markets. In this work a class of mixture models is developed, in order to allow for the coexistence of different distributions of unemployment in the population. These models make possible an interpretation of long-term unemployment allowing for: (a) the estimation of the duration model referred only to individuals with some opportunity of transition to employment, thus eliminating the bias due to the joint estimation of the mixture of two different populations; (b) pointing out the distinctive features (as age, gender, education) related to the disadvantaged side of the population. An empirical application of mixture models on a longitudinal sample coming from the rotating sample structure of the Italian labour force survey is presented, also considering the correction to take into account problems related to length bias.

RESTCLK: a communication paradigm for observation and control of object interaction
Creators: name: Das, Souripriya
Publisher: name: Rutgers University
Year: 1999

description: This dissertation introduces a new communication paradigm, RESTCLK, that extends programmatic observation and control (O&C) to the communication network. In a RESTCLK-based distributed application system, any software object with requisite privileges may suspend and resume the ow of data and examine and modify the data in transit over RESTCLK communication networks. Abstractions and protocols used in RESTCLK allow dynamic changes to be performed in RESTCLK communication networks while maintaining transparency with respect to the application objects, that is, without requiring their knowledge or participation. Support for transparency and dynamicity in RESTCLK networks leads to a unique set of significant features of O&C in RESTCLK including: (1) Objects in a system need not be aware of O&C happening around them; (2) O&C may be performed selectively at any point in a RESTCLK communication network and for any data in transit; and (3) O&C may be recursively performed on O&C itself. O&C capabilities in RESTCLK lead to several significant benefits, especially in the context of dynamic reconfiguration of distributed application systems: (1) Software objects used in building application systems need not be designed to accommodate future dynamic reconfigurations of application systems; (2) Ability to perform even a priori unplanned dynamic reconfigurations; (3) Reduction in complexity of object source codes through elimination of reconfiguration related coordination logic from source codes; (4) Enhanced reusability of object source codes. We also discuss use of RESTCLK in several other contexts: In situ testing of new versions of software in their actual target operational environments without jeopardizing correctness of, and with minimal interference to, the services provided by the current versions; Data in transit may be dynamically encrypted and protected as and when need arises over any part of the communication network; Fault management strategies may be dynamically incorporated into an application system. A proof-of-concept distributed prototype system has been implemented that supports RESTCLK abstractions by providing APIs for use by application system developers. Several well-known applications have been implemented using this prototype to demonstrate some of the benefits of RESTCLK

description: This study models the individual and dyadic associations between relational uncertainty, indirect communication about sexual intimacy, and sexual satisfaction within marital relationships. A sample of 220 married couples completed questionnaires about their sexual relationship and hypotheses were tested using structural equation modeling. Results indicated that (a) relational uncertainty is positively associated with indirect communication about sexual intimacy for both husbands and wives, (b) indirect sexual communication is negatively associated with husbands’ and wives’ own sexual satisfaction, (c) husbands’ and wives’ sexual satisfaction and indirectness about sexual intimacy are positively associated, and (d) husbands’ and wives’ indirect communication about sexual intimacy are negatively associated with their spouse’s sexual satisfaction. The results are discussed in terms of their implications for understanding the dynamics of sexual intimacy within marriage.

description: Starch hydrolysates are in the form of glucose syrups obtained after hydrolysis and with a brownish/yellowish colour caused during processing and preservation. Activated carbon (AC) adsorption is the most used method for decolourising glucose syrups. It is responsible for high costs leading to significant AC consumption and a waste product that needs to be appropriately disposed of and treated. This work evaluated the decolourisation of starch hydrolysates, using AC in combination with Ultrafiltration (UF) to develop a cost and resource-effective downstream process in the future.

description: Background: Mother-to-child HIV transmission (MTCT) has substantially declined since the scale-up of prevention programs around the world, including Rwanda. To achieve full elimination of MTCT, it is important to understand the risk factors associated with residual HIV transmission, defined as MTCT at the population-level that still occurs despite universal access to PMTCT. Methods: We performed a case control study of children born from mothers with HIV with known vital status at 18 months from birth, who were followed in three national cohorts between October and December 2013, 2014, and 2015 in Rwanda. Children with HIV were matched in a ratio of 1:2 with HIV-uninfected children and a conditional logistic regression model was used to investigate risk factors for MTCT. Results: In total, 84 children with HIV were identified and matched with 164 non-infected children. The median age of mothers from both groups was 29 years (interquartile range (IQR): 24–33). Of these mothers, 126 (51.4 %) initiated antiretroviral therapy (ART) before their pregnancy on record. In a multivariable regression analysis, initiation of ART in the third trimester (Adjusted Odds Ratio [aOR]: 9.25; 95 % Confidence Interval [95 % CI]: 2.12–40.38) and during labour or post-partum (aOR: 8.87; 95 % CI: 1.92–40.88), compared to initiation of ART before pregnancy, increased the risk of MTCT. Similarly, offspring of single mothers (aOR: 7.15; 95 % CI: 1.15–44.21), and absence of postpartum neonatal ART prophylaxis (aOR: 7.26; 95 % CI: 1.66–31.59) were factors significantly associated with MTCT. Conclusions: Late ART initiation for PMTCT and lack of postpartum infant prophylaxis are still the most important risk factors to explain MTCT in the era of universal access. Improved early attendance at antenatal care, early ART initiation, and enhancing the continuum of care especially for single mothers is crucial for MTCT elimination in Rwanda.
A survey design for monitoring butterflies

Year: 2013

description: A technique commonly used for surveying butterflies is the Pollard - Yates method (Pollard, 1977; Pollard and Yates, 1993). This method was originally developed for surveying butterflies at Monks Wood, UK (Pollard et al., 1975) and is now widely used in the UK. The method is based on a count of the number of butterflies seen along a fixed survey route. The Pollard - Yates method is easy to implement in the field but it does not allow for differences in the ability to detect butterflies among sites. Line transect sampling (Buckland et al., 1993) has similar survey methods to Pollard - Yates except that distance data is collected and used to estimate a detection function. Therefore, one of the main advantages of line transect sampling is that it provides estimates of abundance that are comparable among sites regardless of the sites' "butterfly-detectability". In addition, it can be used to derive unbiased estimates of local-site densities provided key assumptions are met (Brown and Boyce, 1996, 1998). We introduce some aspects of survey design for a monitoring scheme established for Karner blue butterflies (Lycaeides Melissa samuelis) in Wisconsin, USA.

Geometric morphometrics and the analysis of variations in facial form: robusticity of biological findings in relation to bilateral versus unilateral and missing landmarks
Creators: name: Strand Vidarsdottir, U.
name: O'Higgins, P.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna

description: This paper reviews some recent advances in the analysis of form variability amongst objects described in terms of landmark configurations. Emphasis is given to the methods of geometric morphometrics that utilise the geometry of Kendall's shape space. This space has well understood and desirable statistical properties. Geometric morphometric methods preserve the geometry of the landmark configurations at every step of analysis and so enable ready visualisation of statistical findings. The methods are illustrated by reference to two example analyses of biological shape variability within growth series of facial skeletons. The first is a study of growth and sexual dimorphism in monkeys and the second is a study of human facial growth. Since the material is biological it is to be expected that its morphogenesis generates correlations amongst landmarks. Thus, the face is bilateral symmetrical, with bilateral as opposed to unilateral landmarks likely contributing little new information about underlying patterns of growth. Further, any one landmark is unlikely to be sited on a region that shows a completely uncorrelated pattern of a variation with the regions on which the other landmarks are sited. This paper investigates the effects of using bilateral as opposed to unilateral landmarks, and of missing landmarks, on the ultimate biological interpretation of analyses. Our empirical findings in these studies to indeed indicate considerable stability of biological findings when diverse landmark sets are chosen. These findings reflect on the degree of morphological integration amongst diverse anatomical regions in the face.

Software distributed shared memory over virtual interface architecture: implementation and performance
Creators: name: Rangarajan, Murali

Publisher: name: Rutgers University
Year: 2000

description: In this paper, we describe an implementation of a software Distributed Shared Memory (DSM) over Virtual Interface Architecture (VIA) for a Linux-based cluster of PCs and evaluate its performance. VIA is a user-level memory-mapped communication model that provides zero-copy communication and low-overhead by excluding the operating system kernel from the communication path. To our best knowledge, our implementation is the first software DSM protocol on VIA. The DSM protocol we have implemented on VIA is Home-based Lazy Release Consistency (HLRC) that previous studies have shown to exhibit good scalability by reducing the number of messages and memory overhead compared to the homeless counterpart. The experimental results obtained on seven Splash-2 applications show that VIA can be successfully used to support software shared memory on clusters of PCs. The paper is accompanied by a source-code distribution of the software DSM protocol for Linux/VIA clusters.
Combinatorial complexity of signed discs

description: Let $CC^+$ and $CC^-$ be two collections of topological discs of arbitrary radii. The collection of discs is `topological' in the sense that their boundaries are Jordan curves and each pair of Jordan curves intersect at most twice. We prove that the region $cupCC^+ -cupCC^-$ has combinatorial complexity at most $10n-30$ where $p=|CC^+|$, $q=|CC^-|$ and $n=p+qge 5$. Moreover, this bound is achievable. We also show bounds that are stated as functions of $p$ and $q$. These are less precise.

description: In some paper whose aim is to detect the model of sustainable development, it is simple to note that the actual models present in the System of national Accounts (SEC, SNA), are not able to give the ecessary information about the relation between economy and environment. The main approaches in this field such as SEEA, NAMEA, SERIEE, SIP, still present problems as the difficulties to make a good classification, and to attribute the different types of pollution to the economic factor of pressure. This paper shows a statistical approach finalized to a partial solution of these problems. In particular, it is analysed an Italian region (Basilicata) with sufficient environmental statistical information about one kind of pollution. The aim is to make some statistic multivariate analyses of territorial typizations, of the variability of the observed phenomenon of different kinds of the pollution existing in the territory and finally, of the procedure to identify the economic variables of pressure. The results are encouraging in giving new possibilities to analyse pollution problem with a new approach (whereas in past, the dates were analysed only with the threshold value of the single monitored variables). This is useful both for the building up of integrate model of "economic and environmental National Accounts" and for the individualization of relations between economic and antropic activity and the respective environmental output.

Coherent electromagnetic control of quantum systems
Quantum Klystron

description: Coherent electromagnetic control of quantum systems is usually done by electromagnetic radiation - which does not permit addressing single site-selected quantum systems, especially in the microwave range. In our proof of concept experiment we want to couple for the frst time the non-radiative electromagnetic near-feld of a spatially modulated electron beam to a quantum system in a coherent way as has been proposed lately. As the quantum system we use the unpaired electron spins of a free radical organic sample (Koelsch radical - α,γ-bisdiphenylene-β-phenylallyl) that is excited via the near-feld of the aloof electron beam. The readout of the spin excitation resembles a classic continuous wave electron spin resonance experiment and is done inductively via a microcoil (Fig 1.1) using a lock-in amplifer. The long term perspective of this experiment is the ability to coherently drive and investigate quantum systems in a spatial volume way below the difraction limit of traditional electromagnetic wave based excitation schemes. The spatially confned excitation using an electron beam could also be realized within an electron microscope. Within the last year we have been able to improve the setup, couple the electron beam to the microcoil and reduce noise sources as well as started preparations to cool down the microcoil setup to cryogenic temperatures for enhanced signal to noise ratio.

description: In conditions of uncertainty, information regarding an unknown entity (a physical quantity, an event, a risk) can derive from multiple sources. Hence, the coherent synthesis of heterogeneous sources of knowledge, often with different informative weight, must pass through a Bayesian composition of the available information.
With reference to Peter A. Morris' Bayesian aggregative algorithm (1974, 1977, 1983, 1986) and a fiducial modelisation of the calibration function for the experts' opinions (Monari e Agati, 2001), this paper addresses the problem of the performance indicator variances assessment: the proposed solution is based on the Delta method, that uses the Taylor formula to make derivable functions linear.

description: Coherent manipulation of quantum systems generally relies on electromagnetic radiation as produced by lasers or microwave sources. In the experiment presented here we attempt a novel approach to drive quantum systems, as it was recently proposed (D. Rätzel, D. Hartley, O. Schwartz, P. Haslinger, A Quantum Klystron - Controlling Quantum Systems with Modulated Electron Beams. Phys. Rev. Research 3, 023247, 2021). This method utilizes the non-radiating near-field of a modulated electron beam to coherently drive quantum systems, leading to new possibilities for controlling quantum states. For instance, one can locally address subsystems far below the diffraction limit of electromagnetic radiation or paint potentials at atomic scales. In this proof of concept experiment, we want to couple the oscillating near-field of a spatially modulated electron beam to the unpaired spins of a solid, organic radical sample (BDPA) or the hyperfine levels of laser cooled Potassium atoms. The electron beam is generated with a cathodic ray tube from a fast analog oscilloscope.

description: The comparison of nucleotide substitutions rates between DNA sequences has two major difficulties: rates are result of pairwise comparisons between sequences so they are not independent, and the statistical distribution of this rates is unknown. Moreover the sample is sometimes small, which can limit the use of statistical  methods. So, the comparisons of the evolutionary behaviour of genes through analysis of nucleotide substitution rates should be done using appropriate  statistical approach. In the present study a statistical procedure is proposed to overcome these difficulties.

A dynamic study of the work-fertility relationship in Italy

Year: 2013

description: The paper analyses the relationship between reproductive behaviour and working career of the woman on the basis on data deriving from the Fertility Survey carried out in Italy in 1995/96. In the Italian context, characterised both by the fertility in the world and a low women participation to the labour force, the study of the dynamic relationship between fertility and work participation is very relevant, considering the complex development of the Italian society, both for the women and labour market condition. By means of a logistic multilevel multiple-spell duration model, our analysis shows that the educational/work process influences the timing of the transition to motherhood: women tend to bear their first child after the conclusion of the educational process. Moreover, having a job after this process represents a cause of a greater delay in the moment of child bearing, but the final intensity of the process is quite similar whatever is the educational /working pattern.
The working path changes both the timing and the final intensity of the second child, and these effects are quite different in the North , Centre and South of Italy. Our model enables us to use the casual approach correcting for the distortion in the parameter estimation deriving from the non-exogeneity of working career, taking into account possible common unobservable. The presence of a significant random working effect and of a significant correlation between the two random components of the model means that the effect of the working career on the fertility process depends on unobservable characteristics of each woman.

description: Background: While patient-reported treatment dissatisfaction is considered an important factor in determining the success of substance use disorder treatment, the levels of dissatisfaction with opioid agonist therapies (OAT) and its relationship with the risk of fentanyl exposure have not been characterized in the context of the ongoing opioid overdose crisis in the US and Canada. Our primary hypothesis was that OAT dissatisfaction was associated with an increased odds of fentanyl exposure. Methods: Our objective was to examine self-reported treatment satisfaction among OAT patients in Vancouver, Canada and the association with fentanyl exposure. Longitudinal data were derived from 804 participants on OAT enrolled in two community-recruited harmonized prospective cohort studies of people who use drugs in Vancouver between 2016 and 2018 via semi-annual interviews and urine drug screens (UDS). We employed multivariable generalized estimating equations to examine the relationship between OAT dissatisfaction and fentanyl exposure. Results: Out of 804 participants (57.0% male), 222 (27.6%) reported being dissatisfied with OAT at baseline and 1070 out of 1930 observations (55.4%) had fentanyl exposure. The distribution of OAT reported in the sample was methadone (n = 692, 77.7%), buprenorphine-naloxone (n = 82, 9.2%), injectable OAT (i.e., diacetylmorphine or hydromorphone; (n = 65, 7.3%), slow-release oral morphine (n = 44, 4.9%) and other/study medication (n = 8, 1.0%). In the multivariable analysis, OAT dissatisfaction was positively associated with fentanyl exposure (AOR = 1.34; 95% CI: 1.08–1.66). Conclusions: A substantial proportion of OAT patients in our sample reported dissatisfaction with their OAT, and more than half were exposed to fentanyl. We also found that those who were dissatisfied with their OAT were more likely to be exposed to fentanyl. These findings demonstrate the importance of optimizing OAT satisfaction in the context of the ongoing opioid overdose crisis.

description: In this paper the use of neural networks in the solution of a classification problem is described and a non parametric classifier which combines radial basis function networks (RBF networks) and binary classification trees is proposed. It is  shown that from a classification tree a class of RBF networks can be derived, whose elements differ  in the degree of dependence from the discriminant rules described by the tree. A simulation study based on a two-class problem shows that the proposal represents a valid solution, particularly in presence of noisy variables.

Electron microscopy

description: Electron spin resonance is a widely used analytical tool in medicine, biology and material sciences. Traditionally, electron spin systems are driven by microwaves, which offers only limited spatial resolution due to the long wavelength of microwaves, which can be optimized by sophisticated techniques such as the use of magnetic field gradients. We propose a different way of driving spin systems using the non-radiative near-field of a modulated electron beam in a scanning electron microscope by tuning the microscopes to higher beam currents and using additional beam modulation mechanisms. Driving systems with higher harmonics of the modulated beam opens up future possibilities to perform in-situ electron spin resonance analysis with high spatial resolution down to the nanoscale. To perform our experiments we modified an Philips XL30 ESEM to allow for high frequency beam modulation, cryogenic cooling of our samples and microwave frequency readout of our spin systems.
Instruction scheduling in the presence of Java’s runtime exceptions

description: One of the challenges present to a native code Java compiler is Java’s frequent use of runtime exceptions. These exceptions affect performance directly by requiring explicit checks, as well as indirectly by restricting code movement in order to satisfy Java’s precise exception model. Instruction scheduling is one transformation which is restricted by runtime exceptions since it relies heavily on reordering instructions to exploit maximum hardware performance. The goal of this study was to investigate the degree to which Java’s runtime exceptions hinder instruction scheduling, and to find new techniques for allowing more efficient execution of Java programs containing runtime exceptions.

description: The migration project represents a rational and thought-out choice which occurs a few years before migration itself. The choice is made within the family contests according to laws underlying the family's economy, where every member plays a precise role. The sample this works deals with aims at analysing the relationship network that workers from Tunisia, concentrated in an italian region, maintain with their country of origin. The study tries to determine whether the process of working and cultural integration in the recipient area causes a progressive permanent break these people and their country or whether it favours and reinforces their desire to go back, which is often found among emigrants. The migrant's adaptation and innovation in the receiving country as well as his economic behaviour (saving and remittance capability) which is strictly related to "production return", besides favouring the immigrant's personal economic growth, also triggers important mechanism in the co-operation process between two countries.

description: Nachtlüftung ist eine energieeffiziente Möglichkeit das Risiko einer Überwärmung von Gebäuden zu minimieren, welches durch den klimawandelbedingten Temperaturanstieg bereits in den Übergangszeiten zu beobachten ist. Primär in Nichtwohngebäuden erfordert diese Art der Lüftung jedoch eine entsprechende Regelungstechnik zum effizienten Betrieb. Dazu wird eine Software-in-the-Loop Simulation mit der Gebäudesimulationssoftware IDA ICE verwendet, um die Effizienz von Regelkonzepten zu testen und simulationsgenierte Daten für das Training von Künstlichen Neuronalen Netzwerken (KNN) in einer modellprädiktiven Steuerung (MPC) zu gewinnen. Der vorliegende Ansatz kombiniert die Stärken von Simulation und KNN, indem zuerst die Simulation anhand echter Messdaten kalibriert wird und die resultierenden Simulationsoutputs dann benutzt werden, um ein KNN mit (zusätzlichen) Trainingsdaten zu versorgen. Das resultierende KNN bietet eine vergleichbare Vorhersagegenauigkeit, bei sehr viel geringerem Rechenaufwand und ohne dezidierte Simulationssoftware in die Regelung zu integrieren. Um dies zu erreichen wurde einerseits ein Ersatzmodell für Kipplüftung entwickelt, damit die Simulation diese bei Nachtlüftung typische Öffnungsart berücksichtigt, und ein ver-allgemeinertes Konzept zur Integration von beliebigen physischen Steuergeräten und unterschiedlichen Softwareplattformen in IDA ICE umgesetzt. Das Paper demonstriert sowohl die Machbarkeit als auch das Verbesserungspotential durch die quantitativ wesentlich höhere Anzahl an Trainingsdatensätzen aus Simulationen, die auch Betriebszustände umfassen, die im normalen Gebäudebetrieb häufig nicht wiederholbar sind.

A sample selection model for protest votes in contingent valuation analyses

description: Observations with protest votes in contingent valuation surveys could result in biased estimates of the willingness to pay measure, if treated as expressions of genuine indifference to public good or simply removed from the analysis. We propose an elicitation design and a sample selection model that allow correction of the possible bias due to protest votes. An application shows that selection bias can sensibly affect the estimate of the value of the public good. Inference in sample selection models may sometimes be difficult due the flatness of the likelihood function that causes uncertainty about the presence of selection bias. Even so, we recommend use of the sample selection model, since it takes into account this uncertainty.

description: From the point of view of an institutional management, we consider the problem of evaluating a set of competing supplies of a type of service, possibly from various perspectives of interest, by adopting multiple criteria. To develop evaluator-goals oriented comparative evaluation system, a multi-indicator approach is outlined which is based  on a conceptual framework. It includes the accounting criteria, which the menagement would adopt as grounds for his evaluations. To formalize the complex relations between the realized performance indicators (outcomes) and quantities of allocated resources (input), taking into account specific context conditions, a structered stochastic model is used which considers the latent profile of interest for the evaluator-management. To assign scores on the space of this profile, for each supplier, the differential between the statistical prediction and the base-line (target) value - to be pretended, taking into account the allocated resources, conditional on the specific context conditions - is calculated, up to standardizations. It measures the degree of disagreement of the actual performance with that demanded by the management. An approach has been outlined which automatically calibrates the rules which assign these targets, in a formal empirical Bayes setup, but in the perspective of the Total Quality Management which tends to "prescribes" rather than "explain" performances. Qualitative comparative analysis could be performed analysing multi-dimensional plots of scores, possibly using dynamical graphical tools.

description: Type III phosphatidylinositol 4 kinases (PI4KIIIs) are essential enzymes that are related to the replication of multiple RNA viruses. Understanding the interaction mechanisms of molecular compounds with the alpha and beta isoforms of PI4KIII (PI4KIIIα and PI4KIIIβ) is of significance in the development of inhibitors that can bind to these two enzymes selectively. In this work, molecular dynamics (MD) simulations and binding free energy calculations were combined to investigate the binding modes of seven selected compounds to PI4KIIIα and PI4KIIIβ. Analyses based on MD trajectories provide detailed interaction mechanisms of these compounds with PI4KIIIα and PI4KIIIβ at the atomic level, and indicate that the selectivity of these compounds is mainly due to the structural difference of the binding pockets. It is expected that the detailed binding information found in this study can provide useful help for the structure-based design of selective inhibitors toward PI4KIIIα and PI4KIIIβ.
