The Effect of Daughters on Partisanship (2010)

Washington (2008) finds that, controlling for total number of children, each additional daughter makes a member of Congress more likely to vote liberally and attributes this finding to socialization. However, daughters' influence could manifest differently for elite politicians and the general citizenry, thanks to the selection gradient particular to the political process. This study asks whether the proportion of female biological offspring affects political party identification. Using nationally-representative data from the General Social Survey, we find that female offspring induce more conservative political identification. We hypothesize that this results from the change in reproductive fitness strategy that daughters may evince.
Deep-Sea Lobsters of the Families Polychelidae and Nephropidae (Crustacea, Decapoda) in the Gulf of Mexico and Caribbean Sea. (1971)

Abstract : A preliminary report on the deep-sea lobsters of the families Polychelidae and Nephropidae with particular emphasis upon their occurrences in the Gulf of Mexico and central Caribbean Sea is presented. Taxonomic keys to species in both families are provided. Particularly in the case of the Polychelidae an evaluation is made of the relative importance of certain structural traits as taxonomical characters. Consideration is also given to the possibility of vertical breeding migrations in some species of Polycheles. The problem of 'hard' and 'soft' species of the genus Willemoesia is also examined. Some extensions of geographic and vertical range are noted. The maximum size ranges are also extended for several species. The problem of intergrades between Polycheles t. typhlops and Polycheles typhlops perarmatus is discussed thoroughly. The fact that no polychelid has been photographed by bottom cameras aboard the R/V Alaminos in areas where they are known to abound suggests something about their life habits. (Author)

Activation of Human Neutrophil Procollagenase by Stromelysin 2 (1996)

Neutrophil procollagenase (MMP-8) was efficiently activated by incubation with active stromelysin 2 (MMP-10). A single-step activation mechanism involving the cleavage of the Gly78-Phe79 peptide bond at the end of the propeptide domain was observed. Determination of the collagenolytic activity revealed the generation of active neutrophil collagenase displaying high specific activity. When compared with the specific activity following mercurial activation, which generates active collagenase by autoproteolytic cleavage of either Phe79-Met8O or Met8O-Leu81 peptide bonds [Bläser, J., Knäuper, V., Osthues, A., Reinke, H. & Tschesche, H. (1991) Eur J. Biochem. 202, 1223-1230], the specific activity of the stromelysin-2-activated enzyme was considerably higher. Thus, human neutrophil procollagenase was 'superactivated' by stromelysin 2, as was recently shown for the stromelysin-1-activated enzyme [Knäuper, V., Wilhelm, S. M., Seperack, P. K., De Clerck, Y. A., Langley, K. E., Osthues, A. & Tschesche, H. 1993 a) Biochem. J. 295, 581-586].
Delivering Clean Broadcast Video Over Converged IP Infrastructures (2005)

Delivering high quality full motion video images in the home over broadband has for decades seemed a futuristic dream. Historically, this was more the realm of World Fair displays, science fiction novels and movies than reality. As networking technologies, protocols, and video compression advances have evolved, they have made it possible to deploy broadcast quality video services over converged network infrastructures; these futuristic visions have moved into the real world. These technologies are now mature enough for the “other” VoIP – Video over IP – to take its place in the world of IP networks. But beyond these foundation technologies, what are the performance requirements and enabling technologies for offering such services?
Integrated Triplexer on Hybrid Silicon Platform (2010)

We demonstrated the first laser and photodetector integrated triplexer on silicon with a compact size of 1mm*3.5mm. The 3dB bandwidth for the 1310nm laser and 1490/1550nm photodetector were measured to be 2GHz and 6GHz respectively.
Learning to Visually Navigate in Photorealistic Environments Without any\n Supervision (2020)

Learning to navigate in a realistic setting where an agent must rely solely\non visual inputs is a challenging task, in part because the lack of position\ninformation makes it difficult to provide supervision during training. In this\npaper, we introduce a novel approach for learning to navigate from image inputs\nwithout external supervision or reward. Our approach consists of three stages:\nlearning a good representation of first-person views, then learning to explore\nusing memory, and finally learning to navigate by setting its own goals. The\nmodel is trained with intrinsic rewards only so that it can be applied to any\nenvironment with image observations. We show the benefits of our approach by\ntraining an agent to navigate challenging photo-realistic environments from the\nGibson dataset with RGB inputs only.\n
Transgenic expression of Spi‐C impairs B‐cell development and function by affecting genes associated with BCR signaling (2008)

Spi-C is an Ets family transcription factor closely related to PU.1 and Spi-B. Expression of Spi-C is developmentally regulated in the B-cell lineage, but its function remains unknown. To determine the function of Spi-C in B-cell development, we generated mice expressing a B-cell-specific Spi-C transgene under the control of the IgH intronic enhancer. Spi-C transgenic mice had 50% fewer B cells than wild-type littermates. Flow cytometric analyses showed that splenic transitional B cells and bone marrow pre-B or immature B cells from transgenic mice were dramatically reduced compared with those of wild type. Both nonspecific and Ag-specific serum IgM levels were significantly increased in transgenic mice, while serum IgG levels were significantly decreased compared with wild type. Spi-C transgenic B cells proliferated poorly after stimulation by anti-IgM or anti-CD40 in vitro, although they responded normally to LPS stimulation. Using real-time RT-PCR, we found that several BCR signaling-related mediators were downregulated at pre-B-cell and mature B-cell stages in transgenic mice, while an inhibitor of BCR signaling was upregulated. Taken together, these data indicate that ectopic expression of Spi-C can impair B-cell development and function by affecting genes associated with BCR signaling.
Mechano-Dependent Phosphorylation of the PDZ-Binding Motif of CD97/ADGRE5 Modulates Cellular Detachment (2018)

Cells respond to mechanical stimuli with altered signaling networks. Here, we show that mechanical forces rapidly induce phosphorylation of CD97/ADGRE5 (pCD97) at its intracellular C-terminal PDZ-binding motif (PBM). Biochemically, this phosphorylation disrupts CD97 binding to PDZ domains of the scaffold protein DLG1. In shear-stressed cells, pCD97 appears not only in junctions, retracting fibers, and the attachment area but also in lost membrane patches, demonstrating (intra)cellular detachment at the CD97 PBM. This motif is critical for the CD97-dependent mechanoresponse. Cells expressing CD97 without the PBM are more deformable, and under shear stress, these cells lose cell contacts faster and show changes in the actin cytoskeleton when compared with cells expressing full-length CD97. Our data indicate CD97 linkage to the cytoskeleton. Consistently, CD97 knockout phenocopies CD97 without the PBM, and membranous CD97 is organized in an F-actin-dependent manner. In summary, CD97 shapes the cellular mechanoresponse through signaling modulation via its PBM.
<i>Entamoeba histolytica</i> -Induced Dephosphorylation in Host Cells (2002)

Activation of host cell protein tyrosine phosphatases (PTPases) and protein dephosphorylation is an important mechanism used by various microorganisms to deactivate or kill host defense cells. To determine whether protein tyrosine dephosphorylation played a role in signaling pathways affecting Entamoeba histolytica-mediated host cell killing, we investigated the involvement of PTPases during the attachment of E. histolytica to target cells. We observed a rapid decrease in cellular protein tyrosine levels in Jurkat cells, as measured with an antiphosphotyrosine monoclonal antibody, following adherence to E. histolytica. Ameba-induced protein dephosphorylation was contact dependent and required intact parasite, since blocking amebic adherence with galactose inhibited tyrosine dephosphorylation and amebic lysates had no effect on phosphotyrosine levels. Moreover, disruption of amebic adherence with galactose promoted recovery of phosphorylation in Jurkat cells, indicating that dephosphorylation precedes target cell death. The evidence suggests that ameba-induced dephosphorylation is mediated by host cell phosphatases. Prior treatment of Jurkat cells with phenylarsine oxide, a PTPase inhibitor, inhibited ameba-induced dephosphorylation. We also found proteolytic cleavage of the PTPase 1B (PTP1B) in Jurkat cells after contact with amebae. The calcium-dependent protease calpain is responsible for PTP1B cleavage and enzymatic activation. Pretreatment of Jurkat cells with calpeptin, a calpain inhibitor, blocked PTP1B cleavage and inhibited ameba-induced dephosphorylation. In addition, inhibition of Jurkat cell PTPases with phenylarsine oxide blocked Jurkat cell apoptosis induced by E. histolytica. These results suggest that E. histolytica-mediated host cell death occurs by a mechanism that involves PTPase activation.
Source Coding with Distortion through Graph Coloring (2007)

We consider the following rate distortion problem: given a source X and correlated, decoder side information Y, find the minimum encoding rate for X required to compute f(X,Y) at the decoder within distortion D. This is a generalization of the classical Wyner-Ziv setup and was resolved by Yamamoto (1982). However, this result involved an auxiliary random variable that lacks explicit meaning. To provide a more direct link between this variable and the function f, Orlitsky and Roche (2001) established the minimal rate required in the zero-distortion case as an extension of Korner's graph entropy. Recently, we (with Jaggi) showed that the zero-distortion rate can be achieved by minimum entropy graph coloring of an appropriate product graph. This leads to a modular architecture for functional source coding with a preprocessing "functional coding" scheme operating on top of a classical Slepian-Wolf source coding scheme. In this paper, we give a characterization of Yamamoto's rate distortion function in terms of a reconstruction function. This (non-single-letter) characterization is an extension of our previous results as well as Orlitsky and Roche's results. We obtain a modular scheme operating with Slepian-Wolf's scheme for the problem of functional rate distortion. Further, we give an achievable rate (with single-letter characterization) utilizing this scheme that intuitively extends our previous results.

Antibody Responses in Patients with Staphylococcal Septicemia against Two <i>Staphylococcus aureus</i> Fibrinogen Binding Proteins: Clumping Factor and an Extracellular Fibrinogen Binding Protein (2000)

We analyzed the serum antibody responses against two Staphylococcus aureus fibrinogen binding proteins, the cell-bound clumping factor (Clf) and an extracellular fibrinogen binding protein (Efb). The material consisted of 105 consecutive serum samples from 41 patients suffering from S. aureus septicemia and 72 serum samples from healthy individuals. An enzyme-linked immunosorbent assay (ELISA) was developed. Healthy individuals showed variable levels of antibodies against the studied antigens, and cutoff levels (upper 95th percentile) against these antigens were determined. No correlation was seen between serum antibody levels against Clf and Efb. In acute-phase samples 27% of patients showed positive antibody levels against Clf and 10% showed positive levels against Efb, while in convalescent-phase samples 63% (26 of 41) showed a positive serology against Clf and 49% (20 of 41) showed a positive serology against Efb. Antibody levels against Efb were significantly lower in the acute-phase sera than in sera from healthy individuals (P = 0. 002). An antibody response against Clf was most frequent in patients suffering from osteitis plus septic arthritis and from endocarditis (80% positive). The antibody response against Efb appeared to develop later in the course of disease. A possible biological effect of measured antibodies was demonstrated with the help of an inhibition ELISA, in which both high-titer and low-titer sera inhibited the binding of bacteria to fibrinogen. In conclusion, we have demonstrated in vivo production of S. aureus fibrinogen binding proteins during deep S. aureus infections and a possible diagnostic and prophylactic role of the corresponding serum antibodies in such infections.
Omics in Aid of Host-pathogen Interaction Studies: A Bacterial Perspective (2017)

By providing useful tools to study host-pathogen interactions, next-generation omics has recently enabled the study of gene expression changes in both pathogen and infected host simultaneously. However, since great discriminative power is required to study pathogen and host simultaneously throughout the infection process, the depth of quantitative gene expression profiling has proven to be unsatisfactory when focusing on bacterial pathogens, thus preferentially requiring specific strategies or the development of novel methodologies based on complementary omics approaches. In this review, we focus on the difficulties encountered when making use of omics approaches to study bacterial pathogenesis. Besides, we review different omics strategies (i.e. transcriptomics, proteomics and secretomics) and their applications for studying interactions of pathogens with their host.
Survival and Function of Bioengineered Cardiac Grafts (1999)

Fetal rat ventricular cells can grow 3-dimensionally in a gelatin mesh. The cells in the graft formed cardiac tissue and survived and contracted spontaneously both in tissue culture and after subcutaneous implantation. Future versions of this bioengineered cardiac graft may eventually be used to repair cardiac defects.
Pharmacology of the cardiac endocrine system (1989)

Over the past six years, data and information have accumulated which indicate that the atrial endocrine system and its secreted bioactive peptide(s) are important participants in the regulation of blood pressure and fluid and electrolyte homeostasis (21,12). The nomenclature for atrial peptides includes atrial natriuretic factor, cardionatrin, auriculin, cardiodilatin and the term that we developed, atriopeptin. For the sake of clarity, we will use the terms preproatriopeptin (preproAP), proatriopeptin (proAP), and atriopeptin (AP), when referring to the family of atrial peptides.
Transport of organic electrolytes with electrostatic and steric-hindrance effects through nanofiltration membranes. (1995)

A new model that considers both the electrostatic and steric-hindrance effects based on the space-charge model and the steric-hindrance pore model has been proposed to evaluate the transport phenomena of an organic electrolyte across a nanofiltration membrane. The dependence of the membrane parameters, reflection coefficient and solute permeability on the electrostatic and steric-hindrance effects has been analyzed in the system of an organic electrolyte and a negatively charged nanofiltration membrane. This model has been verified in the system of a tracer organic electrolyte (sodium benzenesulfonate), a supporting salt (sodium chloride) and commercial nanofiltration membranes (Desal-5, NF-40, NTR7450 and G-20); the theoretical values of the membrane reflection coefficients agreed very well with the experimental results of them.
Work Capacity of Regulated Freelance Platforms: Fundamental Limits and Decentralized Schemes (2017)

Crowdsourcing of jobs to online freelance platforms is rapidly gaining popularity. Most crowdsourcing platforms are uncontrolled and offer freedom to customers and freelancers to choose each other. This works well for unskilled jobs (e.g., image classification) with no specific quality requirement since freelancers are functionally identical. For skilled jobs (e.g., software development) with specific quality requirements, however, this does not ensure that the maximum number of job requests is satisfied. In this paper, we determine the capacity of regulated freelance systems, in terms of maximum satisfied job requests, and propose centralized schemes that achieve capacity. To ensure decentralized operation and freedom for customers and freelancers, we propose simple schemes compatible with the operation of current crowdsourcing platforms that approximately achieve capacity. Furthermore, for settings where the number of job requests exceeds capacity, we propose a scheme that is agnostic of that information, but is optimal and fair in declining jobs without wait.
Ni-H/sub 2/ improvements by use of fibrous nickel electrodes (2002)

The behavior of fibrous nickel electrodes working in Ni-H/sub 2/ batteries has been studied in order to lighten these cells. The characteristics of the electrodes have been chosen taking into account the fact that a compromise between the swelling of electrodes and their capacity had to be defined. Cycling tests in accelerated geostationary mode are reported with this type of cell; 900 cycles have already been obtained without any decrease in performance. The end of discharge cell voltage is practically constant and a capacity equal to approximately 90% of the nominal capacity is recovered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Acetylation of GATA-1 is required for chromatin occupancy (2006)

All 3 hematopoietic GATA transcription factors, GATA-1, GATA-2, and GATA-3, are acetylated, although the in vivo role of this modification remains unclear. We examined the functions of an acetylation-defective mutant of GATA-1 in maturing erythroid cells. We found that removal of the acetylation sites in GATA-1 does not impair its nuclear localization, steady-state protein levels, or its ability to bind naked GATA elements in vitro. However, chromatin immunoprecipitation (ChIP) experiments revealed that mutant GATA-1 was dramatically impaired in binding to all examined cellular target sites in vivo, including genes that are normally activated and repressed by GATA-1. Together, these results suggest that acetylation regulates chromatin occupancy of GATA-1. These findings point to a novel function for transcription factor acetylation, perhaps by facilitating protein interactions required for stable association with chromatin templates in vivo.
Total applied shear in capillary extrusion (1972)

Abstract Viscoelastic properties of polymer fluids are single‐valued functions of shear stress or shear rate only at high total applied shear. These parameters may vary with applied shear under milder shear histories. The mean total shear in capillary extrusion is shown to be a function of orifice geometry. Apparent flow curves can be measured at various total shear values by changing the length/radius ratio of the capillary. The true shear stress and true shear rate at the orifice wall correspond to infinite total shear conditions. The true flow curve and elastic parameters like die swell are not measured at equivalent total shear unless the capillary is extremely long.
A Study of Optimisation Approaches to Probabilistic Relaxation Labelling on a 3 Node 2 Label Problem (1987)

We present a comparative study of several optimisation approaches used in probabilistic relaxation labelling. For test purposes, we propose a 3 node 2 label variant of Rosenfelds famous triangle labelling problem. Experiments comparing Rosenfelds original probability updating rule with the theoretically better justified projected gradient method of Hummel et al show that the latter is to preferred.
TEM sample preparation for cultured neurons on a glass coverslip (2005)

Cultured neurons from Drosophila brain on a glass coverslip to understand the structural basis of synapse were prepared for TEM observations. Neurons on a coverslip were fixed, dehydrated and embedded in Epon without separating from coverslip. After polymerization, the block was placed in 49% hydrofluoric acid to remove the coverslip. The block was examined under a light microscope to select exact neurons, then trimmed and sectioned for TEM observation.
