Diversity Interference Cancellation for GSM/EDGE using Reduced-Complexity Joint Detection (2005)

In cellular mobile radio systems, multiple access is causing interference that limits capacity of the networks. The GSM system with multiple users can be interpreted as MIMO system with a desired user and (cochannel and adjacent channel) interferers. Using a multiple-- input multiple--output (MIMO) multiuser joint detection approach for desired signal and one or more (strongest) interferers, network capacity can be significantly increased. In this paper, we compare different multiuser detection methods that can be applied to GSM/EDGE (Enhanced Data Rates for GSM Evolution) systems with Gaussian minimum--shift keying (GMSK) modulation in up- and downlink and 8--ary phase--shift keying (8PSK) in the uplink, respectively. Since an optimal solution is not feasible in these applications, joint MIMO reduced--state sequence estimation (RSSE) with adaptive thresholds in metric computations is applied to reduce computational complexity. The M-algorithm is explored as a second method for joint detection with reduced complexity. Algorithms for multiuser detection are compared with interference rejection methods, where interferers are suppressed by filtering. A performance comparison is done by simulations for the GSM/EDGE equalizer test (EQ) and typical urban (TU) channel profiles with known channel impulse responses at the receiver.
Synthesis and Structural Analysis of ϵ‐Fe2O3 (2005)

Abstract Powder material of ϵ‐Fe 2 O 3 was obtained by thermal decomposition of the clay mineral nontronite and subsequent isolation of the ferric oxide by leaching the silicate phases. Additionally, crystals of ϵ‐Fe 2 O 3 were grown as precipitates by internal oxidation of a Pd 96 Fe 4 alloy. Analysis of the precipitate crystals by electron diffraction yields an orthorhombic crystal system and space group Pna 2 1 ab initio . X‐ray diffraction data of the powder containing small amounts of Al substituting Fe were refined by the Rietveld method. The refinement yields lattice parameters a = 507.15 pm, b = 873.59 pm and c = 941.78 pm, and atom positions. ϵ‐Fe 2 O 3 is isostructural with κ‐Al 2 O 3 , AlFeO 3 , and GaFeO 3 having an anion stacking sequence /ABAC/, and 1/4 of the cations in tetrahedral co‐ordination. Some strongly distorted FeO 6 octahedrons with one large Fe‐O distance, which may be considered as a 5+1 co‐ordination, appear to be characteristic for ϵ‐Fe 2 O 3 . The structure shows elements known from silicates and oxyhydroxides of iron, respectively.

Childhood self-control forecasts the pace of midlife aging and preparedness for old age (2021)

The ability to control one's own emotions, thoughts, and behaviors in early life predicts a range of positive outcomes in later life, including longevity. Does it also predict how well people age? We studied the association between self-control and midlife aging in a population-representative cohort of children followed from birth to age 45 y, the Dunedin Study. We measured children's self-control across their first decade of life using a multi-occasion/multi-informant strategy. We measured their pace of aging and aging preparedness in midlife using measures derived from biological and physiological assessments, structural brain-imaging scans, observer ratings, self-reports, informant reports, and administrative records. As adults, children with better self-control aged more slowly in their bodies and showed fewer signs of aging in their brains. By midlife, these children were also better equipped to manage a range of later-life health, financial, and social demands. Associations with children's self-control could be separated from their social class origins and intelligence, indicating that self-control might be an active ingredient in healthy aging. Children also shifted naturally in their level of self-control across adult life, suggesting the possibility that self-control may be a malleable target for intervention. Furthermore, individuals' self-control in adulthood was associated with their aging outcomes after accounting for their self-control in childhood, indicating that midlife might offer another window of opportunity to promote healthy aging.
CoCOA: A Framework for Comparing Aggregate Client Operations in BPO Services (2016)

Operational efficiency is a major indicator by which the profitability of a business process outsourcing (BPO) service is evaluated. To measure such operational efficiency, BPO service providers define and monitor a set of key performance indicators (KPI) (e.g., productivity of employees, turn-around-time). While a pair of clients can be directly compared using a KPI, comparing the aggregate client operations across multiple KPIs is non-trivial. This is primarily because KPIs are disparate in nature (e.g., cost is measured in dollar while turn-around-time is measured in minutes). In this paper, we present CoCOA, a framework that compares aggregate operations of clients in BPO services so that they can be viewed in a single pane of glass. Two key modules of CoCOA are: (a) client rank aggregator and (b) KPI importance classifier. For a given time period, the rank aggregator module determines an aggregate ranking of clients using variety of inputs (e.g., individual KPI rank, priority of a KPI). When the aggregate rank of a client deteriorates over successive time periods, KPI importance classifier identifies the responsible KPIs for such deterioration. Thus, CoCOA not only helps in comparing the aggregate operation of clients, but also provides prescriptive analytics for improving organizational performance for a given client. We evaluate our approach using anonymized data set collected from a real BPO business and show how responsible KPIs can be identified when there is a deterioration in aggregate client rank.
High Refractive Index Polymers Based on Thiol–Ene Cross-Linking Using Polarizable Inorganic/Organic Monomers (2012)

The self-initiation of the thiol–ene coupling reaction of tetravinyl monomers containing main group elements and trivinyl heterocycles with alkyl and aryl dithiols resulted in the formation of highly cross-linked prepolymer gels which upon final curing at 120 °C yielded hard, monolithic polymeric materials. Because of the presence of highly polarizable main group elements such as Si, Ge, Sn, and S and the relative absence of highly electronegative elements, the resulting polymers exhibited high refractive indices ranging from 1.590 to 1.703 and Abbe numbers between 24.3 and 45.0. All of the polymers were highly transparent over the UV–vis region of the spectrum. Moreover, due to the high cross-linked density achievable in specific compositions, very hard materials capable of being ground and polished could be produced. The range of compositions produced yields important structure–property relationships, indicating the effect of monomer structure on mechanical and optical properties.

Truthful approximation mechanisms for restricted combinatorial auctions: extended abstract (2002)

When attempting to design a truthful mechanism for a computationally hard problem such as combinatorial auctions, one is faced with the problem that most efficiently computable heuristics can not be embedded in any truthful mechanism (e.g. VCG-like payment rules will not ensure truthfulness).We develop a set of techniques that allow constructing efficiently computable truthful mechanisms for combinatorial auctions in the special case where only the valuation is unknown by the mechanism (the single parameter case). For this case we extend the work of Lehmann O'Callaghan, and Shoham, who presented greedy heuristics, and show how to use IF-THEN-ELSE constructs, perform a partial search, and use the LP relaxation. We apply these techniques for several types of combinatorial auctions, obtaining truthful mechanisms with provable approximation ratios.
Whole-Cell Pertussis Vaccine Induces Low Antibody Levels in Human Immunodeficiency Virus-Infected Children Living in Sub-Saharan Africa (2009)

The WHO recommendations for the immunization of children infected with human immunodeficiency virus (HIV) differ slightly from the guidelines for uninfected children. The introduction of antiretroviral therapy for HIV-infected infants should considerably prolong their life expectancy. The question of the response to the whole-cell pertussis (wP) vaccine should now be addressed, particularly in countries in which pertussis remains endemic. To evaluate the persistence of antibodies to the wP vaccine in HIV-infected and uninfected children who had previously received this vaccine in routine clinical practice, we conducted a cross-sectional study of children aged 18 to 36 months, born to HIV-infected mothers and living in Cameroon or the Central African Republic. We tested blood samples for antibodies to the wP vaccine and for antibodies to diphtheria and tetanus toxoids (D and T, respectively) in the context of the use of a combined DTwP vaccine. We enrolled 50 HIV-infected children and 78 uninfected, HIV-exposed children in the study. A lower proportion of HIV-infected children than uninfected children had antibodies against the antigens tested for all valences of the DTwP vaccine. Agglutinin levels were substantially lower in HIV-infected than in HIV-exposed but uninfected children (30.0% versus 55.1%, respectively; P = 0.005). We also observed a high risk of low antibody levels in response to the DTwP vaccine in HIV-infected children with severe immunodeficiency (CD4 T-cell level, <25%). The concentrations of antibodies induced by the DTwP vaccine were lower in HIV-infected children than in uninfected children. This study supports the need for a booster dose of the DTwP vaccine in order to maintain high antibody levels in HIV-infected children.
Modelling of failure mode transition in ballistic penetration with a continuum model describing microcracking and flow of pulverized media (2002)

Abstract An Erratum has been published for this article in International Journal for Numerical Methods in Engineering 2002; 55(4):499–501. A new continuum model to describe damage, fragmentation and large deformation of pulverized brittle materials is presented. The multiple‐plane‐microcracking (MPM) model, developed by Espinosa, has been modified to track microcracking on 13 orientations under high pressure, high strain rate and high deformation. This model provides the elastic and inelastic response of the material before massive crack coalescence. When pulverization occurs, the constitutive response is modelled by means of a visco‐plastic model for granular material, which is a generalization to three dimensions of the double‐sliding theory augmented by a consolidation mechanism. The initialization of the granular model is governed by a yield surface at the onset of massive crack coalescence. This is accomplished by examining a representative volume element, modelled using the MPM model, in compression‐shear. The main advantage of this approach is to keep a continuum model at all stages of the deformation process and thus avoid the difficulties of crack representation in a discrete finite element code. This model has been implemented in LS‐DYNA and used to examine interface defeat of long rod penetrators by a confined ceramic plate. The numerical simulations are compared to experiments in order to identify failure modes. The model parameters were obtained independently by simulating plate and rod impact experiments. The proposed model captures most of the physical observations as well as failure mode transition, from interface defeat to full penetration, with increasing impact velocity.

Sampling Overhead Analysis of Quantum Error Mitigation: Uncoded vs. Coded Systems (2020)

Quantum error mitigation (QEM) is a promising technique of protecting hybrid quantum-classical computation from decoherence, but it suffers from sampling overhead which erodes the computational speed. In this treatise, we provide a comprehensive analysis of the sampling overhead imposed by QEM. In particular, we show that Pauli errors incur the lowest sampling overhead among a large class of realistic quantum channels having the same average fidelity. Furthermore, we show that depolarizing errors incur the lowest sampling overhead among all kinds of Pauli errors. Additionally, we conceive a scheme amalgamating QEM with quantum channel coding, and analyse its sampling overhead reduction compared to pure QEM. Especially, we observe that there exist a critical number of gates contained in quantum circuits, beyond which their amalgamation is preferable to pure QEM.
Portable and Error-Free DNA-Based Data Storage (2016)

Abstract DNA-based data storage is an emerging nonvolatile memory technology of potentially unprecedented density, durability, and replication efficiency 1,2,3 , 4,5,6 . The basic system implementation steps include synthesizing DNA strings that contain user information and subsequently reading them via high-throughput sequencing technologies. All existing architectures enable reading and writing, while some also allow for editing 3 and elementary sequencing error correction 3,4 . However, none of the current architectures offers error-free and random-access readouts from a portable device. Here we show through experimental and theoretical verification that such a platform may be easily implemented in practice using MinION sequencers. The gist of the approach is to design an integrated pipeline that encodes data to avoid synthesis and sequencing errors, enables random access through addressing, and leverages efficient portable nanopore sequencing via new anchored iterative alignment and insertion/deletion error-correcting codes. Our work represents the only known random access DNA-based data storage system that uses error-prone MinION sequencers and produces error-free readouts with the highest reported information rate and density.
A Measure of Improvement of the Shell Egg Grading System (2015)

Dept. of International Trade, Konkuk University, Chungju 380-701, KoreaABSTRACT Eggs are an important source of protein for the human diet. Consumers want fresher, more delicious and more sanitary eggs. In Korea, the Shell Egg Grading system (EGS) was employed in 2001. The portion of graded shell eggs has increased every year, but graded shell eggs account for only 6% of all eggs. The EGS should satisfy producers, distributors and consumers. However, the EGS does not have an official function because of many problems. Consumers cannot select various graded shell eggs in the market, and producers do not receive enough profit even though they produce top-quality graded shell eggs. There are few studies on the EGS, Therefore, this study was performed to improve the EGS. We surveyed the EGS, GP Centers and farmers. Large companies (farmers) are more satisfied than small companies with the EGS. There was a high tendency for the companies (farmers) that are not involved with the EGS to think that graded and ungraded shell eggs are similar, in contrast to the companies (farmers) connected to the EGS. We should have to change the grading system of grade shell eggs, establish of the cold chain system, change of the law for the school meals, minimize payment for the grading shell eggs for developing EGS. Based on this study, the egg industry can benefit through the improvement of the EGS.(key words : shell egg grading system, graded shell eggs, GP center, cold chain system)
SiC UV Detectors under Heavy Ions Irradiation (2015)

4 H -SiC ultraviolet photodetectors based on Schottky barriers have been formed on lightly doped n-type epitaxial layers grown by chemical vapor deposition method on industrial substrates. The diode structures were irradiated at 25°C with 167 MeV Xe ions at a fluence of 6x10 9 cm -2 . Comparative studies of the optical and electrical properties of initial and irradiated structures with Schottky barriers were carried out in temperature range 23-180°C. Swift heavy ion stimulated changes in photosensitivity and electrical characteristics of the initial and irradiated detectors are explained in terms of the fluctuation traps model with the subsequent thermal dissociation.
Tunable Mid-infrared ZnGeP_2 RISTRA OPO pumped by periodically-poled Rb:KTP optical parametric master-oscillator power amplifier (2012)

A laser-diode pumped Q-switched single-frequency Nd:YAG MOPA operating at 100 Hz was used to generate tunable mid-infrared radiation between 6.27 µm and 8.12 µm by employing a cascaded parametric arrangement consisting of degenerate parametric master-oscillator power amplifier using a large aperture periodically-poled Rb:KTiOPO4 which in turn pumped a ZnGeP2 (ZGP) nonplanar RISTRA OPO. The noncollinear ZGP RISTRA tuning behavior is elucidated. The device is aimed for minimally invasive surgery applications at 6.45 µm where the peak power of 193 kW in 5 ns pulses is demonstrated.

[Effects of intravascular contrast media on urinary excretion of liver fatty acid-binding protein]. (2005)

Proximal tubules of the kidney produce liver fatty acid-binding protein (L-FABP) and the level of messenger RNA is increased by physical and chemical stimuli. In this study, changes in urinary excretion of L-FABP were examined in 18 patients without renal dysfunction and who had undergone angiography using iodinated contrast media. On the day following angiography, the urinary excretion of L-FABP was markedly increased by 578 % (p<0.001) as compared with the value before the administration of contrast media. The urinary N-acetyl-beta-D-glucosaminidase excretion was also increased by +93%, however, the extent was less marked than for L-FABP. The urinary L-FABP excretion swiftly returned to the basal level on the second day after the angiography. No patient showed an increase in serum creatinine concentration, and the changes in urinary excretions of other microproteins, such as beta2-microglobulin and alpha1-microglobulin, were not significant. These results suggest that the urinary excretion of L-FABP sensitively reflects the injurious stress on renal tubules. Monitoring of urinary L-FABP may be useful in detecting the development of contrast media nephropathy at an early stage.
Characterization of SiPM: Temperature dependencies (2008)

Within RAPSODI <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> novel types of Silicon Photo-Multiplier (SiPM) from different suppliers were investigated. The main parameters: dark count rate, amplification, dynamic range, quantum detection efficiency and optical cross-talk have been studied to qualify the detectors. Results demonstrate the possibility to apply this detection technology to intense photon fluxes detection as well as to low plurality ones. Characterization protocol for a full SiPM qualification was developed. The most important result is the demonstration of temperature independence of SiPM gain versus over voltage.

Advances in liquid crystal beam steering (2004)

A space platform for optical communications could benefit from nonmechanical beam steering in which no inertia is used to redirect the laser communications link. This benefit is to come in the form of compact, low-power, light-weight optical phased arrays that provide greater flexibility in their steering capability. Non-mechanical beam steering eliminates the need for massive optomechanical components to steer the field of view of optical systems. A phased array approach also allows for random access beam steering. This paper discusses nonmechanical beam steering based on liquid crystal on silicon optical phased array technology. Limitations of the current technology and improvements are presented.
