Automatic 3D face reconstruction from single images or video (2008)

This paper presents a fully automated algorithm for reconstructing a textured 3D model of a face from a single photograph or a raw video stream. The algorithm is based on a combination of Support Vector Machines (SVMs) and a Morphable Model of 3D faces. After SVM face detection, individual facial features are detected using a novel regression- and classification-based approach, and probabilistically plausible configurations of features are selected to produce a list of candidates for several facial feature positions. In the next step, the configurations of feature points are evaluated using a novel criterion that is based on a Morphable Model and a combination of linear projections. To make the algorithm robust with respect to head orientation, this process is iterated while the estimate of pose is refined. Finally, the feature points initialize a model-fitting procedure of the Morphable Model. The result is a highresolution 3D surface model.
Pregnancy‐induced up‐regulation of aquaporin‐4 protein in brain and its role in eclampsia (2005)

Neurologic complications of eclampsia are thought to be similar to hypertensive encephalopathy in which an acute, excessive elevation in blood pressure causes blood-brain barrier (BBB) disruption and edema formation. Because women who develop eclampsia are in general normotensive and asymptomatic prior to pregnancy, we hypothesized that pregnancy alone predisposes the brain to edema formation by up-regulation of aquaporin 4 (AQP4), a water channel in the brain that has been shown to positively correlate with edema formation. To test this hypothesis, we compared localization (immunohistochemistry), mRNA (RT-PCR), and protein levels (Western analysis) of AQP4 in brains from Sprague Dawley rats that were nonpregnant (NP, proestrous), mid-pregnant (MP, days 9-10), late-pregnant (LP, days 19-20), and postpartum (PP, days 3-4). AQP4 mRNA was detected in the brains of all the animals and was localized primarily around the brain parenchymal blood vessels, strongly implicating its role in BBB function. Western analysis revealed that the major AQP4 band at approximately 32 kDa was significantly elevated in MP, LP, and PP animals compared with NP by 9-, 22-, and 17-fold, respectively. These results suggest that pregnancy and the postpartum state up-regulate AQP4 protein located around the intraparenchymal blood vessels, a consequence that could promote edema formation when blood pressure is acutely and excessively elevated, as during eclampsia.-Quick, A.

Continuous-wave fiber optical parametric amplifier with 60-dB gain using a novel two-segment design (2003)

An isolator between two fiber segments was used to obtain a continuous-wave fiber optical parametric amplifier (OPA) with 60-dB internal gain. The isolator was placed between two fiber segments to increase the pump stimulated Brillouin scattering threshold. Subdecibel penalties were measured for transmission of 10-Gb/s signals with 35 dB of gain. The bit error rate of the amplified signal was measured in order to quantify the power penalty due to OPA.

Discussion on Integrating Monitoring Data into the Reservoir Management Process (2000)

Abstract Optimum management of oil and gas reservoirs is a continuous, iterative process which encompasses monitoring the reservoir, interpreting the monitoring data, and deciding from the results how best to continue reservoir development and executing those decisions. Monitoring data vary widely in time and space scales. Temporally, they range from continuous to infrequent, episodic measurements; spatially, they range from local well-centric to global reservoir measurements. The reservoir management workflow similarly operates at multiple, parallel time-space scales. A "fast" workflow loop handles continuous well and surface network data (e.g. pressure, temperature, and rate), using fast data handling and fast decision-making to optimize hydrocarbon delivery. A "slow" workflow loop assimilates episodic reservoir data (e.g. time-lapse seismic and borehole reservoir measurements) to optimize reservoir drainage. Reservoir monitoring data are assimilated at the most appropriate time into the reservoir shared earth model, which feeds both the "fast" and "slow" workflow loops. A continuing industry challenge is to determine the best way to do this, since the types of monitoring data are diverse and the volume of data to assimilate is often vast. This paper begins with a review of reservoir monitoring data that are available today, with a focus on the range of time-space scales. A reservoir management workflow is introduced which has multiple time scales appropriate for these data. The paper concludes with a review of key challenges: (1) to develop improved interpretation technologies to unify and integrate the fast well-network centric and slow reservoir-centric workflow loops for faster conversion of measurement signals into information, and (2) to provide fuller support for uncertainties, including determining how the level of uncertainty in the reservoir model changes when assimilating monitoring data.
The lipoprotein VirB7 interacts with VirB9 in the membranes of Agrobacterium tumefaciens (1997)

VirB9 and VirB7 are essential components of the putative VirB membrane channel required for transfer of the T-complex from Agrobacterium tumefaciens into plants. In this report, we present a biochemical analysis of their interaction and cellular localization. A comparison of relative electrophoretic mobilities under nonreducing and reducing conditions suggested that they form thiol-sensitive complexes with other proteins. Two-dimensional gel electrophoresis identified one complex as a heterodimer of VirB9 and VirB7 covalently linked by a disulfide bond, as well as VirB7 homodimers and monomers. Immunoprecipitation with VirB9-specific antiserum isolated the heterodimeric VirB9-VirB7 complex. Incubation with reducing agent split the complex into its constituent VirB9 and VirB7, which further confirmed linkage via cysteine residues. The interaction between VirB9 and VirB7 also was observed in the yeast two-hybrid system. Membrane attachment of VirB9-VirB7 may be conferred by lipoprotein modification, since labeling with [3H]palmitic acid in A. tumefaciens verified that VirB7 is a lipoprotein associated with VirB9. VirB9 and VirB7 showed equal distribution between inner and outer membranes, in accord with their proposed association with the transmembrane VirB complex.
A Novel pH Sensor Current Mode Read-Out Circuit Using Operational Floating Current Conveyor (2006)

This paper presents a novel Ion Sensitive Field Effect Transistor (ISFET), as a pH sensor, read-out circuit that uses three Operational Floating Current Conveyors (OFCC). This read-out circuit provides a linear sensitivity to pH over a wide range (pH values 2-12). Moreover, it provides an output current that is linearly related to the measured pH. It uses only one type of active element (i.e. OFCC) that makes this circuit easier to be both integrated and fabricated using a conventional CMOS process. Our simulation results demonstrate that the read-out circuit works reliably and can be a suitable sensor read-out circuit for lab on a chip biomedical applications.
The role of the skin microbiome in atopic dermatitis: a systematic review (2017)

Dysbiosis is a hallmark of atopic dermatitis (AD). The composition of skin microbiome communities and the causality of dysbiosis in eczema have not been well established. The objective of this review is to describe the skin microbiome profile in AD and address whether there is a causal relationship between dysbiosis and AD. The protocol is registered in PROSPERO (CRD42016035813). We searched PubMed, Embase, Scopus and ClinicalTrials.gov for primary research studies applying culture-independent analysis on the microbiome on AD skin of humans and animal models. Two authors independently screened the full text of studies for eligibility and assessed risk of bias. Because of heterogeneity no quantitative synthesis was done. Of 5735 texts, 32 met the inclusion criteria (17 published: 11 human and six animal studies). The studies varied in quality and applied different methodology. The skin in AD had low bacterial diversity (lowest at dermatitis-involved sites) and three studies showed depletion of Malassezia spp. and high non-Malassezia fungal diversity. The relative abundance of Staphylococcus aureus and Staphylococcus epidermidis were elevated and other genera were reduced, including Propionibacterium. A mouse study indicated that dysbiosis is a driving factor in eczema pathogenesis. The data are not sufficiently robust for good characterization; however, dysbiosis in AD not only implicates Staphylococcus spp., but also microbes such as Propionibacterium and Malassezia. A causal role of dysbiosis in eczema in mice should encourage future studies to investigate if this also applies to humans. Other important aspects are temporal dynamics and the influence of methodology on microbiome data.
A robust gross-to-fine pattern recognition system (2001)

This paper presents a model-based vision recognition engine for planar contours that are scale invariant of known models. Features are obtained by using a constant-curvature criterion and used to carry out efficient coarse-to-fine recognition. A robust shape matching is proposed for comparing contour fragments from scenes with partial occluding. In order to carry out an early pruning of a large portion of the models, hypotheses are only generated for a subset of contours with enough discriminative information. Poor scene contours are used later in validating or invalidating a relatively small set of hypotheses. Since hypotheses are selectively verified, blocking is avoided by extending current matching through pairing of hypotheses, predictive matching, and retrieving the next weighted hypotheses. This avoids the processing of a large number of initial hypotheses. The authors' evaluation shows that a high recognition error results from the use of too small a bucket size because the indexes may fall at random, producing nonrepeatable results. They use a multidimensional hashing scheme with space separation between dense parameter areas to create additional hashing tables. The robustness of the recognition is based on engineering a coarse bucket size to the best tolerance with respect to various sources of noise. Partially occluded scenes having three objects can be recognized with a success rate of 84%. The results are reproducible against changes in scale, rotation, and translation. Due to the selection of robust initial hypotheses and the structure of the selective matching system, the processing time essentially depends on scene complexity with a marginal dependence on database size.

Enhanced Security Mechanism in public key Cryptosystems using Biometric person Authentication (2016)

Security has been a major concern for authentication over networking. Cryptography methods solve the problem of security by various public key cryptosystems method. In public key cryptosystems, authentication provides by either HASH function, MAC (Message Authentication Code) function or Digital Signature. In this work, we are using Biometric based person or sender Authentication using Speech Feature in public key Cryptosystem. Here using public key cryptosystem is Diffie Hellman (DH) algorithm. DH generates a shared secrete key between two parties over insecure communication but DH does not provide Encryption/Decryption and authentication. Man in middle attack or Hacking possible in DH because it does not authenticate the participate. In this work we overcome the authentication and man in middle attack problem by using Biometric based sender authentication. Also the speech encryption and decryption are performing with the message in this work for higher security.
Substrate induction and catabolite repression of the <i>Streptomyces coelicoior</i> glycerol operon are mediated through the GyIR protein (1994)

The pathway for glycerol catabolism in Streptomyces coelicolor is determined by the gylCABX operon, which is transcribed from two closely spaced glycerol-inducible, glucose-repressible promoters. Glucose (or catabolite) repression of gyl is known to be exerted by a general catabolite repression system in which the soluble glucose kinase plays a central role. The gylR gene is contained in a separate glycerol-inducible, weakly glucose-repressible transcription unit immediately upstream from the gyl operon. The role of gylR in the regulation of gyl transcription was assessed by introducing specific null mutations into the chromosomal gylR gene. Direct quantification of gyl transcripts from the gylR null mutants grown on different carbon sources demonstrated that GylR is the repressor of the gylCABX operon and also revealed that GylR functions as a negative autoregulator. Moreover, the transcriptional analysis revealed that the gylR null mutants were relieved of glucose repression of both gylCABX and gylR. We conclude that both substrate induction and catabolite repression of gyl are mediated through the GylR protein. This is the first direct evidence that catabolite repression in Streptomyces is not exerted at the transcriptional level by a general 'catabolite repressor protein'. Models for catabolite repression are discussed.
A Few Remodeling Projects Make Major Impact: The University of New Mexico School of Law Librarys new reading room, reference desk, and classroom reflect the library as a vibrant activity hub (2008)

The University of New Mexico School of Law Library in Albuquerque recently undertook several major and minor remodeling projects. These included creating the Governor Bruce King Archives and Reading Room inside the law library, remodeling our 35-year-old reference and access services desk, creating a classroom within the law library, and replacing carpeting and furniture. Thanks to these updates, the law library went from appearing a little drab and run-down to looking like the colorful, vibrant hub of activity it really is. This article is also available at: http://www.aallnet.org/products/pub_sp0805/pub_sp0805_Impact.pdf. Additional remodeling photographs are available on pp. 9-11 at: http://www.aallnet.org/products/pub_sp0805/pub_sp0805_MoreArch.pdf.
Selection of Tuning Parameters, Solution Paths and Standard Errors for Bayesian Lassos (2016)

Penalized regression methods such as the lasso and elastic net (EN) have become popular for simultaneous variable selection and coefficient estimation. Implementation of these methods require selection of the penalty parameters. We propose an empirical Bayes (EB) methodology for selecting these tuning parameters as well as computation of the regularization path plots. The EB method does not suffer from the “double shrinkage problem” of frequentist EN. Also it avoids the difficulty of constructing an appropriate prior on the penalty parameters. The EB methodology is implemented by efficient importance sampling method based on multiple Gibbs sampler chains. Since the Markov chains underlying the Gibbs sampler are proved to be geometrically ergodic, Markov chain central limit theorem can be used to provide asymptotically valid confidence band for profiles of EN coefficients. The practical effectiveness of our method is illustrated by several simulation examples and two real life case studies. Although this article considers lasso and EN for brevity, the proposed EB method is general and can be used to select shrinkage parameters in other regularization methods.

Role of Magnetic Resonance Urethrography in Evaluation of Male Urethral Stricture Against Conventional Retrograde Urethrography (2018)

Introduction: Magnetic Resonance Urethrography (MRU) is a new and less widely used technique in the evaluation of male urethral strictures. Aim: This study intends to establish the role of MRU in the evaluation of male urethral strictures and to compare the efficacy with that of conventional Retrograde Urethrography (RUG). Materials and Methods: A total of 32 patients with symptoms of poor urinary stream and straining during micturition underwent conventional RUG followed by MRU. The parameters studied by RUG and MRU such as stricture site, number, length, diameter and associated false tracts or diverticulum were compared with intraoperative findings, which is taken as gold standard. The sensitivity, specificity, positive and negative predictive values of all the parameters was calculated. Karl pearson correlation coefficient and Wilcoxon’s signed rank test were used where appropriate. A p-value of <0.05 was considered statistically significant. Results: Both modalities had 100% sensitivity and specificity in the detection of stricture site. MRU showed better correlation with surgical findings than RUG in strictures less than 3 cm and the RUG showed better correlation with surgical findings than MRU in strictures longer than 3 cm, even though there was no significant statistical difference between the two. Stricture lengths in four cases of long penile urethral strictures with submeatal extension were underestimated by MRU. RUG overestimated the length of four cases of penile urethral stricture. Both RUG and MRU slightly overestimated the severity of strictures in the 2 to 4 mm diameter range. RUG detected all the false tracts, whereas MRU failed to detect one of the false tracts. Accuracy in the detection of spongiofibrosis in MRU was directly proportional to the severity, with no false negatives in moderate to severe degrees of spongiofibrosis. Conclusion: RUG and MRU are equally efficacious in detecting urethral strictures. MRU showed better stricture length assessment in bulbar urethra and accurately delineated posterior urethral distraction defect. MRU effectively detects and characterises spongiofibrosis, which is not possible in RUG.
Estimation of the cell loss ratio in ATM networks with a fuzzy system and application to measurement-based call admission control (1997)

An important parameter in asynchronous transfer model (ATM)-based network design and management is the cell loss ratio (CLR) in ATM multiplexers. It is a key parameter to many vital functions in the network such as call admission control (CAC), bandwidth allocation, etc. However, the CLR depends usually on many unknown and unpredictable traffic parameters such as input traffic correlations. In this paper, we propose a simple and robust fuzzy-based algorithm to predict the CLR in large-sized systems based on both a small amount of information from small-sized systems, and the asymptotic behavior for very large systems. Unlike the model-based approaches, our approximation avoids the problem of assuming any traffic parameters or arrival process. This algorithm is used with real-time traffic measurement to propose an effective measurement-based call admission control framework for ATM networks.
Apratoxin H and Apratoxin A Sulfoxide from the Red Sea Cyanobacterium <i>Moorea producens</i> (2013)

Cultivation of the marine cyanobacterium Moorea producens, collected from the Nabq Mangroves in the Gulf of Aqaba (Red Sea), led to the isolation of new apratoxin analogues apratoxin H (1) and apratoxin A sulfoxide (2), together with the known apratoxins A-C, lyngbyabellin B, and hectochlorin. The absolute configuration of these new potent cytotoxins was determined by chemical degradation, MS, NMR, and CD spectroscopy. Apratoxin H (1) contains pipecolic acid in place of the proline residue present in apratoxin A, expanding the known suite of naturally occurring analogues that display amino acid substitutions within the final module of the apratoxin biosynthetic pathway. The oxidation site of apratoxin A sulfoxide (2) was deduced from MS fragmentation patterns and IR data, and 2 could not be generated experimentally by oxidation of apratoxin A. The cytotoxicity of 1 and 2 to human NCI-H460 lung cancer cells (IC₅₀ = 3.4 and 89.9 nM, respectively) provides further insight into the structure-activity relationships in the apratoxin series. Phylogenetic analysis of the apratoxin-producing cyanobacterial strains belonging to the genus Moorea, coupled with the recently annotated apratoxin biosynthetic pathway, supports the notion that apratoxin production and structural diversity may be specific to their geographical niche.
