Joint Learning of Single-Image and Cross-Image Representations for Person Re-identification (2016)

Person re-identification has been usually solved as either the matching of single-image representation (SIR) or the classification of cross-image representation (CIR). In this work, we exploit the connection between these two categories of methods, and propose a joint learning frame-work to unify SIR and CIR using convolutional neural network (CNN). Specifically, our deep architecture contains one shared sub-network together with two sub-networks that extract the SIRs of given images and the CIRs of given image pairs, respectively. The SIR sub-network is required to be computed once for each image (in both the probe and gallery sets), and the depth of the CIR sub-network is required to be minimal to reduce computational burden. Therefore, the two types of representation can be jointly optimized for pursuing better matching accuracy with moderate computational cost. Furthermore, the representations learned with pairwise comparison and triplet comparison objectives can be combined to improve matching performance. Experiments on the CUHK03, CUHK01 and VIPeR datasets show that the proposed method can achieve favorable accuracy while compared with state-of-the-arts.

Insertion of an intracisternal A particle within the 5'-regulatory region of a gene encoding folate-binding protein in L1210 leukemia cells in response to low folate selection. Association with increased protein expression. (1992)

We have previously described a subline of L1210 murine leukemia cells (LL1) selected in a low level of 5-formyltetrahydrofolate which overexpresses a membrane-bound folate-binding protein (FBP1) and exhibits a rearrangement at the locus encoding this protein. Genomic clones containing the entire FBP1-encoding DNA from both L1210 and LL1 were isolated and characterized. Sequence analysis indicates that, with exception of the 5'-region, the FBP1-encoding locus in both cell lines is identical. The rearrangement in LL1 results from the insertion of an intracisternal A particle (IAP) in the head-to-head (antisense) orientation 72 base pairs (bp) upstream of the FBP1 ATG start codon. The IAP likely provides an alternative promoter for FBP1 expression which may produce a novel transcript with enhanced stability. Presence of the IAP appears to inactivate or relocate normal cis-acting regulatory sequences as expression of the FBP1 transcript in LL1 is not regulated by the folate status of the cell.
Keeled millipedes (Diplopoda: Polydesmida: Paradoxosomatidae) in New South Wales (2009)

Of the keeled millipede families that comprise the order Polydesmida, Paradoxosomatidae is the most widespread and abundant in Australia, yet it is poorly known in New South Wales. This study has added 152 new and undescribed species to the existing 50. Most specimens in established collections were found in the coastal areas where paradoxosomatids are active for most of the year, but indications are that there are many species in the drier areas of the State that would be found only with targeted collecting efforts.
Towards Trainable Media: Using Waves for Neural Network-Style Training (2015)

In this paper we study the concept of using the interaction between waves and a trainable medium in order to construct a matrix-vector multiplier. In particular we study such a device in the context of the backpropagation algorithm, which is commonly used for training neural networks. Here, the weights of the connections between neurons are trained by multiplying a `forward' signal with a backwards propagating `error' signal. We show that this concept can be extended to trainable media, where the gradient for the local wave number is given by multiplying signal waves and error waves. We provide a numerical example of such a system with waves traveling freely in a trainable medium, and we discuss a potential way to build such a device in an integrated photonics chip.
AgSK1, a novel carcinoma associated antigen. (1993)

An IgM human monoclonal antibody (HuMAb) SK1 was generated from mesenteric nodal lymphocytes of a colon cancer patient that were fused with a human B-lymphoblastoid cell line SHFP-1. The reactivities of HuMAb SK1 to various human cell lines were screened by cell enzyme linked immunosorbent assay and immunocytochemical staining. The HuMAb SK1 reacted strongly with all 11 human carcinoma cell lines that were tested and had no detectable binding with noncarcinoma cell lines of the following origins: fibroblast; fetal lung; melanoma; soft tissue sarcoma; neuroblastoma; and glioblastoma. Carcinoma preferred reactivity of HuMAb SK1 was further confirmed by immunoperoxidase staining of a large number of frozen tissues, both malignant and benign. The antigen SK1 (AgSK1) in human carcinoma detected by immunoperoxidase staining was also identified biochemically as a sialoglycoprotein that migrated at M(r) 42,000 with an isoelectric point (pI) of approximately 5.9. A preferential staining by HuMAb SK1 was seen among colorectal, gastric, pancreatic, and lung cancers. Competitive inhibition study in solid-phase immunoassay suggested that the HuMAb SK1 did not cross-react with other antibodies specific for CEA, CA 19-9, and TAG 72. The AgSK1 appears to be a novel carcinoma associated antigen which may be a useful tumor marker in cancer diagnosis and treatment.
Rapid Prototyping of Activity Recognition Applications (2008)

The CRN Toolbox enables fast implementation of activity and context recognition systems, featuring mechanisms for distributed processing and support for mobile and wearable devices. CRN Toolbox is a tool set specifically optimized for implementing multimodal, distributed activity and context recognition systems running on Posix operating systems. Like conventional rapid- prototyping tools, the CRN Toolbox contains a collection of ready-to-use algorithms (signal processing, pattern classification, and so on). Unlike classic event detection in homogeneous sensor networks-for example, DSWare (Data Service Middleware)-it supports complex activity detection from heterogeneous sensors. Its implementation is particularly optimized for mobile devices. This includes the ability to execute algorithms, whether in floating-point or fixed-point arithmetic, without recoding. Moreover, with its mature functionality, the CRN Toolbox isn't likely to suffer from limited user acceptance as the Context toolkit framework did.

Stimulation of the nitric oxide synthase pathway in human hepatocytes by cytokines and endotoxin. (1992)

Nitric oxide (NO) is a short-lived biologic mediator that is shown to be induced in various cell types and to cause many metabolic changes in target cells. Inhibition of tumor cell growth and antimicrobial activity has been attributed to the stimulation of the inducible type of the NO synthase (NOS). However, there is limited evidence for the existence of such inducible NOS in a human cell type. We show here the induction of NO biosynthesis in freshly isolated human hepatocytes (HC) after stimulation with interleukin 1, tumor necrosis factor (TNF), IFN-gamma, and endotoxin. Increased levels of nitrite (NO2-) and nitrate (NO3-) in culture supernatants were associated with NADPH-dependent NOS activity in the cell lysates. The production of NO2- and NO3- was inhibited by NG-monomethyl L-arginine and was associated with an increase in cyclic guanylate monophosphate release. The data presented here provide evidence for the existence of typical inducible NO biosynthesis in a human cell type.
Risk of human immunodeficiency virus (HIV) transmission by blood transfusions before the implementation of HIV‐1 antibody screening (1991)

Little information is available regarding the risk of human immunodeficiency virus type 1 (HIV-1) infection for patients transfused before routine anti-HIV-1 screening of blood donors was instituted in March 1985. A model was developed for estimating both the proportion and the number of transfusion recipients in the San Francisco Bay area who were infected by HIV-1 during each of the 7 years preceding routine donor screening for anti-HIV-1. The model is based on analysis of 1) donation histories of HIV-1-infected donors identified at the regional blood center; 2) HIV-1 seroprevalence estimates for homosexual and bisexual men in San Francisco; and 3) HIV-1 infection and survival rates for recipients traced by the Transfusion Safety Study and Irwin Memorial Blood Centers' Look Back Program. The incidence of transfusion-associated HIV-1 infection is estimated to have risen rapidly from the first occurrence in 1978 to a peak in late 1982 of approximately 1.1 percent per transfused unit. The decrease after 1982 coincided with the implementation of high-risk donor deferral measures. It is estimated that, overall, approximately 2135 transfusion recipients were infected with HIV-1 in the San Francisco region alone. This number suggests a higher prevalence of transfusion-associated HIV-1 infection than has been generally recognized and indicates the need for continued tracing of potentially exposed recipients. The data also strongly support the effectiveness of early donor education and self-exclusion measures and emphasize the importance of continued research and development in this area.
New Bicyclic Taxane Diterpenoids from Taxus sumatrana (2005)

Investigation of an acetone extract of the leaves and twigs of Taxus sumatrana has resulted in the isolation of two new bicyclic taxoids, tasumatrols M (1), and N (2) and a new baccatin III derivative, tasumatrol O (3) together with the previous known 7-deacetylcanadensene (4) and 2alpha,7beta,13alpha-triacetoxy-5alpha,9alpha-dihydroxy-2(3-->20) abeotaxa-4(20),11-dien-10-one. The structures of these taxanes were established on the basis of spectroscopic analyses, especially 1- and 2D NMR, and chemical derivatization.
Ghilantens: anticoagulant-antimetastatic proteins from the South American leech, Haementeria ghilianii. (1990)

Five proteins with anticoagulant and antimetastatic activities were isolated from the salivary glands of the Amazon leech, Haementeria ghilianil. These proteins, designated ghilantens, were co-purified on DEAE-cellulose and heparin-agarose, and were purified by microbore C-18 reverse-phase HPLC. Each variant had a similar molecular weight (18,000), amino acid composition, and a blocked amino terminus. Ghilantens caused a dose-dependent prolongation of the prothrombin time of normal human plasma and blocked the factor Xa-mediated hydrolysis of methoxycarbonyl-D-cyclohexylglycyl-glycl-arginine-p-nitro anillide acetate. Ghilantens were quantitatively absorbed to bovine factor Xa-AffiGel-15 and were eluted with 0.1 mol/L benzamidine, an active-site reversible inhibitor of factor Xa. These findings show that ghilantens can form a reversible association with the enzyme. When administered intravenously to mice by tall vein injection, ghilantens potently suppressed lung metastases of B16-F10 melanoma cells. These findings suggest that ghilantens may have therapeutic value in the treatment of metastatic disease.
Microbeam radiation therapy (1999)

The central nervous system of vertebrates, even when immature, displays extraordinary resistance to damage by microscopically narrow, multiple, parallel, planar beams of x rays. Imminently lethal gliosarcomas in the brains of mature rats can be inhibited and ablated by such microbeams with little or no harm to mature brain tissues and neurological function. Potentially palliative, conventional wide-beam radiotherapy of malignant brain tumors in human infants under three years of age is so fraught with the danger of disrupting the functional maturation of immature brain tissues around the targeted tumor that it is implemented infrequently. Other kinds of therapy for such tumors are often inadequate. We suggest that microbeam radiation therapy (MRT) might help to alleviate the situation. Wiggler-generated synchrotron x-rays were first used for experimental microplanar beam (microbeam) radiation therapy (MRT) at Brookhaven National Laboratory's National Synchrotron Light Source in the early 1990s. We now describe the progress achieved in MRT research to date using immature and adult rats irradiated at the European Synchrotron Radiation Facility in Grenoble, France, and investigated thereafter at the Institute of Pathology of the University of Bern.
Online check and recovery techniques for dependable embedded processors (2001)

Efficient online check and fast recovery techniques for embedded systems aim to detect single or multiple errors within the same clock cycle in which they occur. It is argued that such techniques can enable fast error correction; detection of illegal states, micro- rollback for transient and permanent faults; and prioritized, controlled recovery.
Alternative splicing of fibronectin: Three variants, three functions (1991)

Fibronectin (FN) is a multi-functional extracellular matrix protein required for cell adhesion and migration, blood clotting, wound healing, and oncogenic transformation. The functional complexity is paralleled by structural diversity in that multiple forms of FN are generated by cell type-specific alternative splicing. In the rat, up to 12 different combinations of the three alternatively spliced segments (EIIIA, EIIIB, and the V region) are produced. What effects do these segments have on FN function? Recently, progress has been made in the identification of specific activities for the three variants of the V region, V120, V95, and V0. FN-mediated cell adhesion, FN synthesis and secretion, and incorporation into blood clots are differentially affected by these isoforms. These results suggest that cellular behavior is modulated by environmental cues provided by different types and proportions of alternatively spliced FN variants.
Staphylococcus aureus interactions with the endothelium (2005)

The intravascular manifestation of Staphylococcus aureus infection is often associated with a severe, and sometimes catastrophic disease. Many host factors contribute to endothelial tropism of S.aureus including subendothelial matrix proteins, endothelial cell receptors, and platelets that are engaged together with S. aureus cell wall adhesins such as the fibronectin binding proteins. Recently, the role of secreted staphylococcal factors that were initially identified by virtue of their binding function with host proteins and ligands, has been reappraised in this regard. Among these, bacterial proteins without significant homology among each other, coagulase (Coa), the extracellular fibrinogen binding protein (Efb), the extracellular matrix binding protein (Emp), or the extracellular adhesive protein (Eap), are the most prominent ones to be associated with endovascular disease. Newly discovered interactions with host components may account for profound effects on immunmodulation and wound healing which are summarized in this short review and which ascribe an important role of these molecules in acute and chronic endo- and extravascular staphylococcal disease. Further research in the complex functional role of these "secretable expanded repertoire adhesive molecules" (SERAM) may not only help to increase our understanding in the pathogenesis of S. aureus infection but can specify novel targets for preventive or therapeutic strategies.
INFLUENCE OF FAT AND CARBOHYDRATE CONTENT OF DIET ON FOOD INTAKE AND GROWTH OF MALE INFANTS (1976)

Two groups of normal fullterm infants were studied from 8 to 112 days of age while receiving formulas of the same caloric density and prepared from the same ingredients. A limited selection of strained foods were permitted. From the combination of formula and strained foods, one group received 29% of calories from fat and 62% from carbohydrate whereas the other received 57% from fat and 34% from carbohydrate. Fifteen infants in each group completed the study as planned. Energy intakes per kilogram and rates of gain in length and weight were similar in the two feeding groups.
Image Interpolation via Graph-Based Bayesian Label Propagation (2014)

In this paper, we propose a novel image interpolation algorithm via graph-based Bayesian label propagation. The basic idea is to first create a graph with known and unknown pixels as vertices and with edge weights encoding the similarity between vertices, then the problem of interpolation converts to how to effectively propagate the label information from known points to unknown ones. This process can be posed as a Bayesian inference, in which we try to combine the principles of local adaptation and global consistency to obtain accurate and robust estimation. Specially, our algorithm first constructs a set of local interpolation models, which predict the intensity labels of all image samples, and a loss term will be minimized to keep the predicted labels of the available low-resolution (LR) samples sufficiently close to the original ones. Then, all of the losses evaluated in local neighborhoods are accumulated together to measure the global consistency on all samples. Moreover, a graph-Laplacian-based manifold regularization term is incorporated to penalize the global smoothness of intensity labels, such smoothing can alleviate the insufficient training of the local models and make them more robust. Finally, we construct a unified objective function to combine together the global loss of the locally linear regression, square error of prediction bias on the available LR samples, and the manifold regularization term. It can be solved with a closed-form solution as a convex optimization problem. Experimental results demonstrate that the proposed method achieves competitive performance with the state-of-the-art image interpolation algorithms.
Highly repeated DNA sequence limited to knob heterochromatin in maize (1981)

A highly repeated DNA sequence has been isolated from the maize genome as a satellite in actinomycin D/CsCl gradients. By using maize stocks differing in their heterochromatin content we have established that the sequence is a major constituent of one class of heterochromatin, knob heterochromatin, which can occur at 23 locations in the chromosome complement. The repeating unit, of 185 base pairs, has been cloned in plasmid pBR322 and its nucleotide sequence has been determined. The presence of this DNA sequence in knob heterochromatin and its absence from centromeric, nucleolar, and B chromosome heterochromatin parallels the cytogenetic differentiation previously described for these classes of heterochromatin in maize. Because knob heterochromatin has a distinctive cytological appearance and is unique in showing neocentric activity at meiosis, its association with a particular repeated DNA sequence may reflect a functional role for the sequence in the cell cycle.
Modulation of the lipid binding properties of the N‐terminal domain of human apolipoprotein E3 (2001)

Apolipoprotein E (apoE) plays a critical role in plasma lipid homeostasis through its function as a ligand for the low-density lipoprotein (LDL) receptor family. Receptor recognition is mediated by residues 130-150 in the independently folded, 22-kDa N-terminal (NT) domain. This elongated globular four-helix bundle undergoes a conformational change upon interaction with an appropriate lipid surface. Unlike other apolipoproteins, apoE3 NT failed to fully protect human LDL from aggregation induced by treatment with phospholipase C. Likewise, in dimyristoylglycerophosphocholine (Myr2Gro-PCho) vesicle transformation assays, 100 microg apoE3 NT induced only 15% reduction in vesicle (250 microg) light scattering intensity after 30 min. ApoE3 NT interaction with modified lipoprotein particles or Myr2Gro-PCho vesicles was concentration-dependent whereas the vesicle transformation reaction was unaffected by buffer ionic strength. In studies with the anionic phospholipid dimyristoylglycerophosphoglycerol, apoE3 NT-mediated vesicle transformation rates were enhanced > 10-fold compared with Myr2Gro-PCho and activity decreased with increasing buffer ionic strength. Solution pH had a dramatic effect on the kinetics of apoE3 NT-mediated Myr2Gro-PCho vesicle transformation with increased rates observed as a function of decreasing pH. Fluorescence studies with a single tryptophan containing apoE3 NT mutant (L155W) revealed increased solvent exposure of the protein interior at pH values below 4.0. Similarly, fluorescent dye binding experiments with 8-anilino-1-naphthalene sulfonate revealed increased exposure of apoE3 NT hydrophobic interior as a function of decreasing pH. These studies indicate that apoE3 NT lipid binding activity is modulated by lipid surface properties and protein tertiary structure.
Sustained expression of human factor VIII in mice using a parvovirus-based vector (2000)

Persistent therapeutic levels of human factor VIII (hFVIII) would signify a major advance in the treatment of hemophilia A. Here we report sustained expression of hFVIII in immunocompetent mice using recombinant adeno-associated virus (rAAV) vectors. AAV can stably transduce liver cells, the target tissue for efficient hFVIII production. Because of rAAV packaging constraints, we tested 2 constructs using small regulatory elements designed for liver-specific transgene expression linked to B-domain-deleted hFVIII (BDD-hFVIII) cDNA. More than 10(12)/mL rAAV/BDD-hFVIII virion particles were generated using a transfection scheme that eliminates adenovirus. Coatest and APTT assays confirmed the production of functional BDD-hFVIII protein after transduction of 293 and HepG2 cells. In vivo experiments were performed in C57BL/6 and NOD/scid mice receiving 10(10-11) rAAV/hFVIII particles via portal vein injection. All C57BL/6 mice tested developed anti-hFVIII antibody. In contrast, NOD/scid mice expressed hFVIII reaching 27% of normal human plasma levels. As expected, we could not detect hFVIII antigen from plasma samples isolated from control animals receiving equivalent doses of rAAV expressing enhanced green fluorescent protein (EGFP). Transgene mRNA expression was detected primarily in the liver and histologic analysis of the liver revealed no pathologic abnormalities. These results demonstrate a promising approach for treatment of hemophilia A. (Blood. 2000;95:1594-1599)
