Continuous manufacturing of thin cover sheet optical media (1992)

A general method for making optical media by a continuous roll process has been developed. The process can accommodate a variety of optical structures, although it has been optimized for those with smaller form factors and thin cover sheets. A test disk was used to demonstrate process capabilities and evaluate media made by this method.
Fingerprint - Iris Fusion Based Identification System Using a Single Hamming Distance Matcher (2009)

Conventional multimodal biometric identification systems tend to have larger memory footprint, slower processing speeds and a higher implementation and operational cost. In this paper we propose a state of the art framework for multimodal biometric identification system which can be adapted for any type of biometrics to provide smaller memory footprint and faster implementation than the conventional multimodal biometrics systems. The proposed framework is verified by development of a fingerprint and iris fusion system which utilizes a single hamming distance based matcher to provide higher accuracy than the individual unimodal system.
Solid-State Chlorine NMR of Group IV Transition Metal Organometallic Complexes (2009)

Static solid-state (35)Cl (I = (3)/(2)) NMR spectra of the organometallic compounds Cp(2)TiCl(2), CpTiCl(3), Cp(2)ZrCl(2), Cp(2)HfCl(2), Cp*(2)ZrCl(2), CpZrCl(3), Cp*ZrCl(3), Cp(2)ZrMeCl, (Cp(2)ZrCl)(2)mu-O, and Cp(2)ZrHCl (Schwartz's reagent) have been acquired at 9.4 T with the quadrupolar Carr-Purcell Meiboom-Gill (QCPMG) sequence in a piecewise manner. Spectra of several samples have also been acquired at 21.1 T. The electric field gradient (EFG) tensor parameters, the quadrupolar coupling constant (C(Q)) and quadrupolar asymmetry parameter (eta(Q)), are readily extracted from analytical simulations of the spectra. The (35)Cl EFG and chemical-shift tensor parameters are demonstrated to be sensitive probes of metallocene structure and allow for differentiation of monomeric and oligomeric structures. First-principles calculations of the (35)Cl EFG parameters successfully reproduce the experimental values and trends. The origin of the observed values of C(Q)((35)Cl) are further examined with natural localized molecular orbital (NLMO) analyses. The combination of experimental and theoretical methods applied to the model compounds are employed to structurally characterize Schwartz's reagent (Cp(2)ZrHCl), for which a crystal structure is unavailable. Aside from a few select examples of single-crystal NMR spectra, this is the first reported application of solid-state (35)Cl NMR spectroscopy to molecules with covalently bound chlorine atoms. It is anticipated that the methodology outlined herein will find application in the structural characterization of a wide variety of chlorine-containing transition-metal and main-group systems.
“Sorry, that's all I know!”: A study on web‐based pragmatic instruction for novice learners (2023)

Abstract This study examines the impact of instructor‐led (IL) versus self‐access (SA) web‐based pragmatic instruction on novice second language learners' ( n = 28) awareness and oral production of Spanish apologies. Two sections of a second‐semester Spanish course were assigned to either the IL or the SA group. The web‐based resource Dancing with Words was used to provide pragmatic instruction. Participants in the SA group worked through the materials individually, and participants in the IL group received support and guidance from the instructor. A quasi‐experimental, pre‐/posttest design was used to measure participants' pragmatic competence (i.e., awareness and production skills) before and after a 5‐week intervention period. Results indicate three major findings: (1) learners follow developmental trajectories similar to those identified in study abroad, (2) instructor guidance is important for novice learners' development of pragmatic competence, and (3) special consideration should be given to instructional materials to ensure they align with the instructional context and goals.

A multiwavelength digital holographic microscope architecture for enhancing life detection (2019)

Spectral properties of living organism can provide a discriminating method for characterization. However, digital holographic microscopy (DHM), a high-resolution, volumetric imaging technique that is well-suited for examining microbial species is typically monochromatic. Thus, the spectral properties of bacteria are not probed with DHM save only for the wavelength of operation. Here we describe a new DHM instrument which enhances the method via the simultaneous recording of wavelength multiplexed holograms of the sample. This coarse spectral encoding is akin to labeling with RGB values, thereby producing colorized images of the species which enables a new dimension of characterization. This new instrument is derived from a previous architecture which has already demonstrated superior opto/mechanical stability. Herein, this novel instrument is described, and the results of experimental measurements taken with this new instrument are shown.
HLA-binding regions of HIV-1 proteins. II. A systematic study of viral proteins (1991)

To detect HLA-binding peptides in 10 HIV-1 proteins (Rev, Tat, Vif, Vpr, Vpu, Gag p18, Gag p24, Gag p15, Env gp120 and Env gp41), the peptide binding assay (PBA) has been performed using three HLA class I molecules. Correlations have been searched between the PBA results and the peptide competitor activity in a functional test using HLA-A2-restricted CTL and target cells. A correlation between the data found in the PBA and well-defined CTL epitopes could be attempted only for the three Gag proteins. For these proteins, our results are in agreement with the known existence of epitopes reacting with human CD8+ CTL, with some exceptions. Together with the results reported with a panel of Nef peptides, these experiments showed that at least 18/20 of the already reported CTL epitopes from HIV-1 Gag, Nef, and Env proteins could be detected by the PBA, most (17/18) corresponding to strong reactivities. Perhaps more important, the regions of HIV-1 Gag p24 or Nef proteins that contain multiple associated CTL epitopes, with different HLA restrictions, were clearly identified by the reactivities in the PBA of several overlapping peptides and the major practical interest of the PBA might be the detection of such polyepitopic regions. Prediction are proposed in this report for 10 proteins, including several proteins for which CTL epitopes remain presently unknown.

HiNF-P Directly Links the Cyclin E/CDK2/p220 NPAT Pathway to Histone H4 Gene Regulation at the G 1 /S Phase Cell Cycle Transition (2005)

Genome replication in eukaryotic cells necessitates the stringent coupling of histone biosynthesis with the onset of DNA replication at the G1/S phase transition. A fundamental question is the mechanism that links the restriction (R) point late in G1 with histone gene expression at the onset of S phase. Here we demonstrate that HiNF-P, a transcriptional regulator of replication-dependent histone H4 genes, interacts directly with p220(NPAT), a substrate of cyclin E/CDK2, to coactivate histone genes during S phase. HiNF-P and p220 are targeted to, and colocalize at, subnuclear foci (Cajal bodies) in a cell cycle-dependent manner. Genetic or biochemical disruption of the HiNF-P/p220 interaction compromises histone H4 gene activation at the G1/S phase transition and impedes cell cycle progression. Our results show that HiNF-P and p220 form a critical regulatory module that directly links histone H4 gene expression at the G1/S phase transition to the cyclin E/CDK2 signaling pathway at the R point.
Exploiting directionality for millimeter-wave wireless system improvement (2015)

This paper presents directional and omnidirectional RMS delay spread statistics obtained from 28 GHz and 73 GHz ultrawideband propagation measurements carried out in New York City using a 400 Megachips per second broadband sliding correlator channel sounder and highly directional steerable horn antennas. The 28 GHz measurements did not systematically seek the optimum antenna pointing angles and resulted in 33% outage for 39 T-R separation distances within 200 m. The 73 GHz measurements systematically found the best antenna pointing angles and resulted in 14.3% outage for 35 T-R separation distances within 200 m, all for mobile height receivers. Pointing the antennas to yield the strongest received power is shown to significantly reduce RMS delay spreads in line-of-sight (LOS) environments. A new term, distance extension exponent (DEE) is defined, and used to mathematically describe the increase in coverage distance that results by combining beams from angles with the strongest received power at a given location. These results suggest that employing directionality in millimeter-wave communications systems will reduce inter-symbol interference, improve link margin at cell edges, and enhance overall system performance.
Application-Level Resource Provisioning on the Grid (2006)

In this paper, we present algorithms for Grid resource provisioning that employ agreement-based resource management. These algorithms allow userlevel resource allocation and scheduling of applications that are structured as a precedenceconstrained set of tasks. We present a provisioning model where the resource availability in the Grid can be enumerated as a set of slots. A slot is defined as a number of processors available from a certain start time for a certain duration at a certain cost. Using a cost model that combines the cost of resource allocation and the expected application runtime, we evaluate the performance of the Min-Min and of the Genetic algorithm (GA)-based heuristics for a range of synthetic applications. We show that the GA paired with a list scheduling algorithm can obtain significantly better solutions than the Min-Min heuristic alone.

Pituitary adenylate cyclase activating polypeptide (PACAP) expression in sympathetic preganglionic projection neurons to the superior cervical ganglion (1998)

Pituitary adenylate cyclase activating polypeptides (PACAP27 and PACAP38) are members of the VIP/secretin/glucagon family of peptides and have diverse neuroregulatory effects in sympathoadrenal cell development and function. PACAP peptides regulate rat superior cervical ganglion (SCG) neuron catecholamine and neuropeptide Y content and secretion, and promote sympathoneuroblast survival through activation of specific PACAP1 receptor isoforms. In examining the potential sources of PACAP regulating the SCG, PACAP expression was identified in rat preganglionic neurons in the intermediolateral cell column (IML) of the thoracic spinal cord which provide primary afferent projections to this sympathetic ganglion. Thoracic spinal cord segments (T1-4) contained approximately 17 pmol PACAP38 immunoreactivity/g tissue wet weight. Reverse-transcription polymerase chain reaction of cDNA from microdissected thoracic spinal cord using primers specific for rat neuronal proPACAP identified proPACAP mRNA expression in the IML; the results correlated with neurons labeled for proPACAP mRNA by in situ hybridization histochemistry and implicated PACAP biosynthesis in IML neurons. To demonstrate directly proPACAP transcript expression in preganglionic projection neurons to the SCG, the ganglion was decentralized and the sympathetic trunk immersed in fluorogold to identify sympathetic preganglionic neurons by retrograde labeling. Cryosections of spinal cord segments containing preganglionic neuron fluorogold labeled neurons were processed subsequently for in situ hybridization histochemical localization of proPACAP mRNA using a digoxigenin-labeled riboprobe; IML neurons were examined for fluorogold and digoxigenin/alkaline phosphatase product dual labeling. More than half of the preganglionic projection neurons to the SCG expressed PACAP mRNA, consistent with the postulate that PACAP peptides released from a subpopulation of thoracic IML preganglionic neurons may be physiological anterograde modulators of sympathetic SCG function.

Data grid management systems (2003)

Data Grids are being built across the world as the next generation data handling systems to manage peta-bytes of inter organizational data and storage space. A data grid (datagrid) is a logical name space consisting of storage resources and digital entities that is created by the cooperation of autonomous organizations and its users based on the coordination of local and global policies. Data Grid Management Systems (DGMSs) provide services for the confluence of organizations and management of inter-organizational data and resources in the datagrid.The objective of the tutorial is to provide an introduction to the opportunities and challenges of this emerging technology. Novices and experts would benefit from this tutorial. The tutorial would cover introduction, use cases, design philosophies, architecture, research issues, existing technologies and demonstrations. Hands on sessions for the participants to use and feel the existing technologies could be provided based on the availability of internet connections.
Genetic Signatures of Demographic Changes in an Avian Top Predator during the Last Century: Bottlenecks and Expansions of the Eurasian Eagle Owl in the Iberian Peninsula (2015)

The study of the demographic history of species can help to understand the negative impact of recent population declines in organisms of conservation concern. Here, we use neutral molecular markers to explore the genetic consequences of the recent population decline and posterior recovery of the Eurasian eagle owl (Bubo bubo) in the Iberian Peninsula. During the last century, the species was the object of extermination programs, suffering direct persecution by hunters until the 70's. Moreover, during the last decades the eagle owl was severely impacted by increased mortality due to electrocution and the decline of its main prey species, the European rabbit (Oryctolagus cuniculus). In recent times, the decrease of direct persecution and the implementation of some conservation schemes have allowed the species' demographic recovery. Yet, it remains unknown to which extent the past population decline and the later expansion have influenced the current species' pattern of genetic diversity. We used eight microsatellite markers to genotype 235 eagle owls from ten Spanish subpopulations and analyse the presence of genetic signatures attributable to the recent population fluctuations experienced by the species. We found moderate levels of differentiation among the studied subpopulations and Bayesian analyses revealed the existence of three genetic clusters that grouped subpopulations from central, south-western and south-eastern Spain. The observed genetic structure could have resulted from recent human-induced population fragmentation, a patchy distribution of prey populations and/or the philopatric behaviour and habitat selection of the species. We detected an old population bottleneck, which occurred approximately 10,000 years ago, and significant signatures of recent demographic expansions. However, we did not find genetic signatures for a recent bottleneck, which may indicate that population declines were not severe enough to leave detectable signals on the species genetic makeup or that such signals have been eroded by the rapid demographic recovery experienced by the species in recent years.
WEAR PROPERTIES OF HIGH-DOSE CROSS-LINKPOLYETHYLENE SHELF-AGED FOR EXTREMELY LONG TERM -A HIP SIMULATION STUDY- (2008)

Different studies have shown that gamma-irradiated polyethylene generally results in degradation by oxidation. On the other hand, we clinically used ultra-high molecular weight polyethylene sterilized by gamma-irradiation of 1,000kGy dose in the air (100Mrad cross-link polyethylene) for total hip prostheses from 1970 to 1978, and excellent clinical results extending for 30 years were shown. In the present study, the wear characteristics were evaluated by hip simulator on 100Mrad cross-link polyethylene cups which were available after shelf-aging for extremely long term (about 30 years). The results are compared with those ofthe explanted cup after 30 years of clinical use as well as the cups aged by acceleration in order to review the influence of aging environments and themechanism of degradation.

The 100Mrad polyethylene cups were manufactured by Mizuho Medical Instruments in the 1970s and they have been in stock on the shelf in air-containing package or without being packed for 30 years. These cups were tested with alumina heads (36mm in diameter) by the AMTI hip-joint simulator.

The 100Mrad polyethylene cup aged for 30 years without a package showed considerable initial wear. In case of the same cup aged in an air-containing package, however, a significant reduction of wear was observed even with the presence of the oxidized surface layer. This observation agreed with the low wear of explanted 100Mrad polyethylene after 30 years of clinical use. These results suggest that wear properties of this gamma-irradiated polyethylene are significantly affected by the environmental conditions it was kept for long period of time.
Ultrafast thin-disk laser with 80  μJ pulse energy and 242  W of average power (2013)

We present a semiconductor saturable absorber mirror (SESAM) mode-locked thin-disk laser generating 80 μJ of pulse energy without additional amplification. This laser oscillator operates at a repetition rate of 3.03 MHz and delivers up to 242 W of average output power with a pulse duration of 1.07 ps, resulting in an output peak power of 66 MW. In order to minimize the parasitic nonlinearity of the air inside the laser cavity, the oscillator was operated in a vacuum environment. To start and stabilize soliton mode locking, we used an optimized high-damage threshold, low-loss SESAM. With this new milestone result, we have successfully scaled the pulse energy of ultrafast laser oscillators to a new performance regime and can predict that pulse energies of several hundreds of microjoules will become possible in the near future. Such lasers are interesting for both industrial and scientific applications, for example for precise micromachining and attosecond science.
Simulation-Based Analysis of Forecast Performance Evaluations for Airline Revenue Management (2009)

Dynamic Intelligent Systems at the University of Paderborn and the German airline Deutsche Lufthansa AG.It includes the consideration of problems occurring in applied revenue management under the aspect of academic research.The goal is to use methodological approaches to airline revenue management, demand forecast and simulation presented in the further text as well as expert knowledge and data available in the industry.The purpose of this text is the development of a new view of forecast performance, in order to avoid some of the complications connected to evaluation of demand forecasts for revenue management.To enable this, a theoretical concept of decomposing and evaluating forecasts under the laboratory conditions provided by a simulation and using information exclusive to simulation environments is developed.To demonstrate the potential of this concept, the implementation of a simulation environment including a choice-based demand model is documented.Finally, a number of statements about the implications of forecast quality and forecast evaluation is expressed formally and tested using simulation experiments to demonstrate the use of the proposed concept.

National Variations in Morbid Obesity and Bariatric Surgery Use (2005)

National estimates suggest that bariatric surgery rates do not parallel the burden of morbid obesity by region or age. Additional evaluation of these differences is necessary for optimal bariatric surgery use.
Post‐transcriptional regulation of C‐C motif chemokine ligand 2 expression by ribosomal protein L22 during LPS‐mediated inflammation (2020)

Monocyte infiltration to the site of pathogenic invasion is critical for inflammatory response and host defence. However, this process demands precise regulation as uncontrolled migration of monocytes to the site delays resolution of inflammation and ultimately promotes chronic inflammation. C-C motif chemokine ligand 2 (CCL2) plays a key role in monocyte migration, and hence, its expression should be tightly regulated. Here, we report a post-transcriptional regulation of CCL2 involving the large ribosomal subunit protein L22 (RPL22) in LPS-activated, differentiated THP-1 cells. Early events following LPS treatment include transcriptional upregulation of RPL22 and its nuclear accumulation. The protein binds to the first 20 nt sequence of the 5'UTR of ccl2 mRNA. Simultaneous nuclear translocation of up-frameshift-1 protein and its interaction with RPL22 results in cytoplasmic degradation of the ccl2 mRNA at a later stage. Removal of RPL22 from cells results in increased expression of CCL2 in response to LPS causing disproportionate migration of monocytes. We propose that post-transcriptional regulation of CCL2 by RPL22 fine-tunes monocyte infiltration during a pathogenic insult and maintains homeostasis of the immune response critical to resolution of inflammation.
