Working Papers on International Economics and Finance DEFI 1203 May 2012 Export Survival in Global Value Chains

This paper focuses on the survival capacity of the trade flows in international production networks, extending the limited empirical evidence. Firstly, we emphasize that these trade relationships are longer-lived than trade in final goods. Secondly, we try to delimit the factors that explain this. Using time-discrete duration models, which control for the existence of unobservable heterogeneity, we find that variables such as initial value of the trade flow, geographic and product diversification, institutional quality, geographic and linguistic proximity and membership in a regional integration agreement play an important role for stability of global production systems. Our results highlight that the high sunk entry costs and the need for trust and reliability in global value chains are factors dissuading radical alterations in the network configuration.

Characterizing control of memory CD8 T cell differentiation by BTB-ZF transcription factor Zbtb20

Members of the BTB-ZF transcription factor family regulate the immune system. Our lab identified that family member Zbtb20 contributes to the differentiation, recall responses and metabolism of CD8 T cells. Here, we report a characterization of the transcriptional and epigenetic signatures controlled by Zbtb20 at single-cell resolution during the effector and memory phases of the CD8 T cell response. Without Zbtb20, transcriptional programs associated with memory CD8 T cell formation were upregulated throughout the CD8 T response. A signature of open chromatin was associated with genes controlling T cell activation, consistent with the known impact on differentiation. Additionally, memory CD8 T cells lacking Zbtb20 were characterized by open chromatin regions with overrepresentation of AP-1 transcription factor motifs and elevated RNA- and protein-level expression of the corresponding AP-1 components. Finally, we describe motifs and genomic annotations from the DNA targets of Zbtb20 in CD8 T cells identified by CUT&RUN. Together, these data establish the transcriptional and epigenetic networks contributing to the control of CD8 T cell responses by Zbtb20.
Analysis and trans-synthesis of acoustic bowed-string instrument recordings - A case study using bach cello suites

In this paper, analysis and trans-synthesis of acoustic bowed string instrument recordings with new non-negative matrix factorization (NMF) procedure are presented. This work shows that it may require more than one template to represent a note according to time-varying behavior of timbre, especially played by bowed string instruments. The proposed method improves original NMF without the knowledge of tone models and the number of required templates in advance. Resultant NMF information is then converted into the synthesis parameters of the sinusoidal synthesis. Bach cello suites recorded by Fournier and Starker are used in the experiments. Analysis and trans-synthesis examples of the recordings are also provided.
Physical and Physiological Characteristics of Elite Indian National Football Players

Background: No profiling studies have been done on the Elite Indian Football players. The purpose of the study was to study the physical and physiological characteristics of Elite Indian Football Players. Methods: In order to explore the physical and physiological characteristics of elite Indian football players and compare these results according to playing positions 28 current and past Indian under/22 years national players (height 1.73 ± 0.03 m; body mass 71.8 ± 2.5 kg; age 25.1 ± 1.1 years) underwent a series of anthropometric, physical and physiological assessments including skinfold assessment, isokinetic knee extensors and flexors strength, vertical jump, maximal ball kick velocity, Yo-Yo Intermittent Recovery Test, Illinois agility test, and sprint performance. Results: Positional differences influenced results. Body fat was lowest (16.0 ± 0.7%) for forwards (p < 0.01) who were also most agile. Midfielders were strongest (p < 0.01) and the most aerobically fit players (p < 0.05). Significant correlations between isometric strength and jumping performance (r = 0.37) and kicking velocity (r = 0.43) were found. Body fat was well correlated to agility (r = 0.70), dynamic knee flexion (r = 0.78) and extension (r = 0.76) strength, and maximal ball kick velocity (r = 0.42). Conclusion: Position specific characteristics appear to exist and need to be considered for training purposes. However, results suggest that currently Indian players are not meeting physical and physiological standards expected for professional international footballers

Methods for polymer-stabilization of molecular orientation in LC-waveguiding structures

In this letter we present a new way for constructing and developing LC-based waveguiding structures. Specifically, liquid crystalline material enriched with monomer in the proper proportions is implemented in our approach and a waveguide geometry can be created in the LC cell thanks to the photo-polymerization process allowing for LC molecules to be suspended in desired position and orientation. The latter can be enforced by external fields and UV-irradiation can be performed trough the mask of desired geometry. In this way, regions with different molecular textures (e.g. planar and homeotropic) and thus waveguiding structures can be easily created within LC layer. The main idea of this letter is not only to show a prove-of-concept of the polymer-imposed LC stabilization for such planar optical devices but to discuss differences in methodology of their practical realization.

Robust logistic regression of family data in the presence of missing genotypes

ABSTRACT Large cohort studies are commonly launched to study the risk effect of genetic variants or other risk factors on a chronic disorder. In these studies, family data are often collected to provide additional information for the purpose of improving the inference results. Statistical analysis of the family data can be very challenging due to the missing observations of genotypes, incomplete records of disease occurrences in family members, and the complicated dependence attributed to the shared genetic background and environmental factors. In this article, we investigate a class of logistic models with family-shared random effects to tackle these challenges, and develop a robust regression method based on the conditional logistic technique for statistical inference. An expectation–maximization (EM) algorithm with fast computation speed is developed to handle the missing genotypes. The proposed estimators are shown to be consistent and asymptotically normal. Additionally, a score test based on the proposed method is derived to test the genetic effect. Extensive simulation studies demonstrate that the proposed method performs well in finite samples in terms of estimate accuracy, robustness and computational speed. The proposed procedure is applied to an Alzheimer's disease study.
Minimal residual disease in adolescent ( older than 14 years ) and adult acute lymphoblastic leukemias : early immunophenotypic evaluation has high clinical value

Investigation of minimal residual disease (MRD) in acute leukemias by immunophenotyping and/or molecular techniques is proving to be increasingly valuable for disease monitoring. In acute lymphoblastic leukemia (ALL), most MRD studies have focused on children, whereas in contrast, information on the value of MRD on adult ALL is scanty, and almost exclusively restricted to polymerase chain reaction (PCR) studies. Early response to therapy is one of the most important prognostic factors in acute leukemia, which prompted us to investigate whether or not early immunophenotypic assessment of MRD could also be a valuable tool for predicting relapse in adult patients with ALL. For that purpose we have analyzed the level of MRD during the initial phase of treatment (induction phase) by multiparameter flow cytometry in a series of 102 adolescent (older than 14 years) and adult patients with ALL. Immunophenotypic evaluation of the bone marrow (BM) at day 35 showed that patients with low MRD levels (< 0.05% leukemiaassociated phenotype [LAP ] cells) had a significantly longer relapse-free survival (RFS) than patients with high MRD levels, and this prognostic influence was retained when only those patients in morphologic complete remission (mCR) at day 35 were considered (median RFS: 42 months vs 16 months; P .001). Moreover, immunophenotyping helped to identify a small subset of patients (n 12) with negative or low MRD levels (< 0.03% LAP cells) by day 14, with an excellent prognosis (projected RFS of 90% at 5 years). The contrary is true of patients who achieved late mCR (after day 35), since immunophenotypic investigation of MRD showed that, in spite of the mCR, none of the cases with more than 0.1% LAP cells would be relapse-free after 2 years. Multivariate analysis showed that the immunologic evaluation of MRD at day 35 was the most relevant independent prognostic parameter for adult patients with ALL, and together with age, white blood cell (WBC) count at diagnosis, and presence of the Philadelphia (Ph) chromosome, represented the most informative combination of variables for predicting relapse-free survival.

ROAD INFRASTRUCTURE DEVELOPMENT AND SOCIAL EQUITY IN PAPUA PERSPECTIVE OF THE POPULATION IN RURAL AREAS IN MAIRASI, KAIMANA REGENCY, WEST PAPUA

……………………. The objective of this present research is to analyze the relationship between the policy of road infrastructure development and social equity in Papua, especially in rural area in Mairasi, Kaimana, West Papua. To get the needed information, a quantitative-qualitative or mixed method was employed to evaluate the policy. An after and before evaluation type was used to analyze the impacts of the socio-economic changes before and after the road was built. This present research was focused on the accessibility impacts on the access to education, health, market and banking. The tool for the analysis was the Wilcoxon Signed Rank Test. The results of the analysis showed that the access to education had the mean value of 2.40 which is higher than that before the roads were built, namely 2.29. The discrepancy is significantly meaningful where the p-value was 2.20. The
Massive MIMO with a Generalized Channel Model: Fundamental Aspects

Massive multiple-input multiple-output (MIMO) is becoming a mature technology, and has been approved for standardization in the 5G space. Although there are many papers on the theoretical analysis of massive MIMO, the majority of relevant work assumes the simplified, yet overly idealistic, Kronecker-type model for spatial correlation. Motivated by the deficiencies of the Kronecker model, we invoke a naturally generalized spatial correlation model, that is the Weichselberger model. For this model, we pursue a comprehensive analysis of massive MIMO performance in terms of channel hardening and favorable propagation (FP). We identify a number of scenarios under which massive MIMO may fail and discuss their relevance from a practical perspective.
On Motion Estimation Problems in Computer Vision

Motion estimation is one of the fundamental problems in computer vision. It has broad applications in the fields of robot navigation, mixed and augmented reality, visual tracking, image and video processing, intelligent transportation systems and so on. Up until now, motion estimation is far from a solved problem, and it is still one of the active research topics in and beyond the computer vision community. This thesis is dedicated to both camera motion estimation – including motion estimation for 3D and 2D cameras – and dense image motion for color images. We push the limits of the state of the art in various aspects such as optimality, robustness, accuracy and flexibility. The main contributions are summarized as follows. First, a globally optimal 3D point cloud registration algorithm is proposed and applied to motion estimation of 3D imaging devices. Based on Branch-and-Bound (BnB) optimization, we optimally solve the registration problem defined in Iterative Closest Point (ICP). The registration error bounds are derived by exploiting the structure of the SE(3) geometry. Other techniques such as the nested BnB and the integration with ICP are also developed to achieve efficient registration. Experiments demonstrate that the proposed method is able to guarantee the optimality, and can be well applied in estimating the global or relative motion of 3D imaging devices such as 3D scanners or depth sensors. Second, a globally optimal inlier-set maximization algorithm is proposed for color camera motion estimation. We use BnB to seek for the optimal motion which gives rise to the maximal inlier set under a geometric error. An explicit, geometrically meaningful relative pose parameterization – a 5D direct product space of a solid 2D disk and a solid 3D ball – is proposed, and efficient, closed-form bounding functions of inlier set cardinality are derived to facilitate the 5D BnB search. Experiments on both synthetic data and real images confirm the efficacy of the proposed method. Third, a scene constraint based method for relative pose estimation between a 2D color camera and a 3D sensor is developed. We formulate the relative pose estimation as a 2D-3D registration problem minimizing the geometric errors from the known scene constraints. Our method takes only a single pair of color and depth images as input, and is correspondence-free. In addition, a new single-view 3D reconstruction algorithm is proposed for obtaining initial solutions. The experiments show that the method is both flexible and effective, producing accurate relative pose estimates and high-quality color-depth image registration results. Fourth, a highly-accurate optical flow estimation algorithm based on piecewise parametric motion model is proposed. It fits a flow field piecewise to a variety of parametric models where the domain of each piece (i.e., shape, position and size) and its model parameters are determined adaptively, while at the same time maintaining a global inter-piece flow continuity constraint. The energy function takes into
The Market for Teacher Quality

Much of education policy focuses on improving teacher quality, but most policies lack strong research support. We use student achievement gains to estimate teacher value-added, our measure of teacher quality. The analysis reveals substantial variation in the quality of instruction, most of which occurs within rather than between schools. Although teacher quality appears to be unrelated to advanced degrees or certification, experience does matter -- but only in the first year of teaching. We also find that good teachers tend to be effective with all student ability levels but that there is a positive value of matching students and teachers by race. In the second part of the analysis, we show that teachers staying in our sample of urban schools tend to be as good as or better than those who exit. Thus, the main cost of large turnover is the introduction of more first year teachers. Finally, there is little or no evidence that districts that offer higher salaries and have better working conditions attract the higher quality teachers among those who depart the central city district. The overall results have a variety of direct policy implications for the design of school accountability and the compensation of teachers.
Coincidence studies of entangled photon pairs using nanowire detection and high-resolution time tagging for QKD application

Entangled photon pairs are created by a system consisting of a 1064 nm pump diode laser that is fiber coupled to a high generation rate photon pair source. The source is a dual element periodically poled potassium titanyl phosphate (KTP) waveguide that up-converts 1064 nm photons to single 532 nm photons in the first stage. In the second stage, the green photons are down converted to energy entangled photon pairs at 800 nm and 1600 nm. The output photon pairs are guided by fiber to sorting optics where they are separated and sent into high-efficiency photon detectors. In particular, the 1600 nm photons are detected by a superconducting nanowire with efficiency over 60% and dead time less than 50 ns. Detector output electrical signals are sent to a time tagger with bin resolution as narrow as 25 ps for coincidence counting. The ultimate goal of this setup is to demonstrate a singlesource, high efficiency, high data rate, quantum communication system to enable Earth-space quantum networks. Of particular interest is a source of entangled photons that is amenable to utilization in aircraft and spacecraft under rigorous flight and environmental conditions. Test results that characterize the entangled photon pair creation and detection capabilities of our system will be presented.
The arithmetic of cuckoldry in family trees

Family history research has become a very popular hobby during the last few years due to the ready access to records of births and marriages. Many people have rigorously traced their ancestors back to 1700 and earlier, corresponding to some 12 generations. The principal motivation of most amateur genealogists is to learn about the lives of their forebears and they trust these ‘legal’ records without question and do not usually acknowledge that cuckoldry may have occurred and that their true ancestors may not have been the ones recorded.
Proceedings of the Annual Meeting of the Cognitive Science Society

Expressing the confidence level of a system’s suggestions by using speech sounds is an important cue to users of the system for perceiving how likely it is for the suggestions to be correct. We assume that expressing the levels of confidence using human-like expressions will cause users to have a poorer impression of a system than if artificial subtle expressions (ASEs) were used when the quality of the presented information does not match the expressed level of confidence. We confirmed that this assumption was correct by conducting a psychological experiment.
of the Annual Meeting of the Cognitive Science Society Title Symbolic Reasoning in Spiking Neurons : A Model of the Cortex / Basal Ganglia / Thalamus Loop

We present a model of symbol manipulation implemented using spiking neurons and closely tied to the anatomy of the cortex, basal ganglia, and thalamus. The model is a generalpurpose neural controller which plays a role analogous to a production system. Information stored in cortex is used by the basal ganglia as the basis for selecting between a set of inferences. When an inference rule is selected, it commands the thalamus to modify and transmit information between areas of the cortex. The system supports special-case and general-purpose inferences, including the ability to remember complex statements and answer questions about them. The resulting model suggests modifications to the standard structure of production system rules, and offers a neurological explanation for the 50 millisecond cognitive cycle time.
Acta Botanica Brasilica

Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and smoke water solution treatment on seed germination of invasive (Melinis minutiflora, Urochloa decumbens, U. brizantha) and native grasses (Axonopus pressus, Aristida setifolia, Gymnopogon foliosus) of the Cerrado. The effect of fire temperature was tested by exposing seeds to heat shock treatments of 60, 100, and 200 °C for one minute, comparing them to untreated seeds. The effect of smoke was tested by soaking seeds for 24-h in an aqueous smoke comparing them to seeds soaked in distilled water. Differences among treatments were evaluated by ANOVA and randomization tests. None of the tested species had germination stimulated by the temperature or smoke. Both species of Urochloa experienced decreased viability with increasing temperature, while seeds of native species and M. minutiflora tolerated heat shock up to 200 °C. The invasive grasses usually germinated faster than the native grasses. Germination time is therefore a crucial trait driving the invasion process, irrespective of fire-related cues. Other seed traits (e.g. dormancy) and higher resprouting capacity may help invasive species to persist in frequently burned savannas.

The sag: A forgotten parameter in need of resurrection?

The advent of large-diameter rigid contact lenses (semi-scleral lenses) has necessitated renewed understanding of the concept of ‘the sag’ of a contact lens and/or cornea. This article reviews the concept of ‘the sag’ and how to calculate the sag for spherical and aspherical surfaces. Reviews of empirical studies investigating the sag of the eye are presented. Data for normal and keratoconic corneas for sags as measured with an Oculus Keratograph are also included. How to include empirical measurements obtained in practice, in the determination of a first-trial semi-scleral lens, is suggested.
