Biometric enhancements: Template aging error score analysis

Identity capabilities are being modernized through biometric technology and systems. With maturing biometrics in full, rapid development, a higher accuracy of identity verification is required. Improvements to the security of biometric verification systems is provided through higher accuracy; ultimately reducing fraud, theft, and loss of resources from unauthorized personnel. With trivial biometric systems, a higher acceptance threshold to obtain higher accuracy rates increased false rejection rates and user unacceptability. However, maintaining the higher accuracy rate enhances the security of the system. Through the methods presented in this paper, higher accuracy rates are obtained without lowering the acceptance threshold, therefore improving the security level, false rejection rates, and user acceptability. An area of biometrics with a paucity of research is template aging, specifically in regards to facial aging. This paper presents methods of modeling and predicting facial template aging based on matching score analysis. A novel foundational framework for facial template aging is presented and provides a methodological framework. The groundwork discusses new techniques used in the template aging framework, to include the ldquoerror score matrixrdquo and ldquodecay error estimaterdquo concepts. The matching scores are calculated using commercially available facial matching algorithms/SDKs against publicly available facial databases. Improved performance error rates while maintaining or improving upon the overall matching and/or rejection levels is accomplished with the new framework. Using such scores, prediction of a timeframe if or when an individual needs to be re-enrolled with a new template is feasible.
Sources , Detectors and Receivers Semiconductor , Superconductor and Other Plasma Wave HEMTs for THz applications

New THz chip solid-state detectors and sources are waited for many applications. The idea of new sources and detectors, based on the oscillations of bidimensional plasma, was theoretically and experimentally demonstrated. We present technological process of nanometric devices dedicated to THz emission. In this structure, a MIM gate-source capacitance is integrated to HEMT to achieve the boundary condition of plasma wave generation and to keep possible the gate biasing, necessary for frequency tuning. High electron mobility material like InAlAs/GaInAs heterostructure is used otherwise the plasma wave is dumped by electron scattering. Electrical and THz measurements are realized.
Mitotic catastrophe and apoptosis induced by docetaxel in hormone‐refractory prostate cancer cells

Studies performed in different experimental and clinical settings have shown that Docetaxel (Doc) is effective in a wide range of tumors and that it exerts its activity through multiple mechanisms of action. However, the sequence of events induced by Doc which leads to cell death is still not fully understood. Moreover, it is not completely clear how Doc induces mitotic catastrophe and whether this process is an end event or followed by apoptosis or necrosis. We investigated the mechanisms by which Doc triggers cell death in hormone‐refractory prostate cancer cells by analyzing cell cycle perturbations, apoptosis‐related marker expression, and morphologic cell alterations. Doc induced a transient increase in G2/M phase followed by the appearance of G0/1 hypo‐ and hyperdiploid cells and increased p21 expression. Time‐ and concentration‐dependent apoptosis was induced in up to 70% of cells, in concomitance with Bcl‐2 phosphorylation, which was followed by caspase‐2 and ‐3 activation. In conclusion, Doc would seem to trigger apoptosis in hormone‐refractory prostate cancer cells via mitotic catastrophe through two forms of mitotic exit, in concomitance with increased p21 expression and caspase‐2 activation.

Mixed Intuitionistic Fuzzy Aggregation Operators decreasing results of unusual IFNs

Aggregation operators for intuitionistic fuzzy information, the popular methods in group decision, face the challenge in this area - counter-intuitive result (the decision result is conflict with people's intuition under specific inputs). In this paper, the Mixed Intuitionistic Fuzzy Aggregation Operators (MIFAOs) are proposed to relieve this problem. Firstly, the Bivariate Mixed Intuitionistic Fuzzy Aggregation Operators (BMIFAOs) are introduced based on the proposed extensions of t-conorms and t-norms. Some basic operational laws are proposed for Archimedean t-conorms and t-norms. Thus, the effects of unusual Intuitionistic Fuzzy Numbers (IFNs) would be decreased on final aggregating results. Secondly, the Multivariate Mixed Intuitionistic Fuzzy Aggregation Operators (MMIFAOs) are proposed, by extending BMIFAOs to higher dimensions. The basic operators are deduced for the Algebraic t-conorms and t-norms. Finally, an illustrative example is utilized to demonstrate the process of aggregating the IFNs by utilizing the proposed MMIFAOs in this paper. The results show that the proposed MIFAOs can relieve the counter-intuitive results for aggregation operators on unusual IFNs.
A role for paclitaxel in the combination chemotherapy of acute myeloblastic leukaemia: preclinical cell culture studies

Paclitaxel dose responses in culture have been investigated alone and in association with cytosine arabinoside (ARA‐C) and all‐trans retinoic acid (ATRA), with the objective of identifying a role for paclitaxel in the treatment of acute myeloblastic leukaemia (AML). Initial studies were done to determine if paclitaxel dose responses of AML blast cell precursors were altered by regulatory compounds known to modify the dose responses of ARA‐C. In contrast to ARA‐C, paclitaxel dose responses were independent of cell culture method, the growth factors G‐CSF and GM‐CSF, and the ligands all‐trans retinoic acid (ATRA) and hydrocortisone. Most blast cell populations were sensitive to paclitaxel; compared with normal marrow progenitors the dose responses were markedly heterogenous with some more, and others less, sensitive. Remission marrow progenitor paclitaxel responses resembled those of AML blasts in heterogeneity. The cell culture model tested the effect of paclitaxel and ATRA on the ARA‐C dose responses of OCI/AML‐5: paclitaxel exposure was either before or after ARA‐C to test for an effect of schedule; ATRA was added to the MEC cultures after paclitaxel and ARA‐C. Repeat experiments were done to test three dose levels each of paclitaxel and ATRA. When paclitaxel was given after ARA‐C, synergism was found for all but one of the dose combinations tested; only three examples of synergy were seen when paclitaxel preceded ARA‐C. The studies justify trials combining ARA‐C, paclitaxel and ATRA using a schedule suggested by the cell culture findings.
The use of an anterior pelvic internal fixator to treat disruptions of the anterior pelvic ring: A REPORT OF TECHNIQUE, INDICATIONS AND COMPLICATIONS

Aims The anterior pelvic internal fixator is increasingly used for the treatment of unstable, or displaced, injuries of the anterior pelvic ring. The evidence for its use, however, is limited. The aim of this paper is to describe the indications for its use, how it is applied and its complications. Patients and Methods We reviewed the case notes and radiographs of 50 patients treated with an anterior pelvic internal fixator between April 2010 and December 2015 at a major trauma centre in the United Kingdom. The median follow‐up time was 38 months (interquartile range 24 to 51). Results Three patients were excluded from the analysis leaving 47 patients with complete follow‐up data. Of the 47 patients, 46 achieved radiological union and one progressed to an asymptomatic nonunion. Of the remaining patients, 45 required supplementary posterior fixation with percutaneous iliosacral screws, 2 of which required sacral plating. The incidence of injury to the lateral femoral cutaneous nerve (LFCN) was 34%. The rate of infection was 2%. There were no other significant complications. Without this treatment, 44 patients (94%) would have needed unilateral or bilateral open reduction and plate fixation extending laterally to the hip joint. Conclusion The anterior pelvic internal fixator reduces the need for extensive open surgery and is a useful addition to the armamentarium for the treatment of anterior pelvic injuries. It is associated with injury to the LFCN in a third of patients.
Multiscale modelling of blood flow in cerebral microcirculation: Details at capillary scale control accuracy at the level of the cortex

Aging or cerebral diseases may induce architectural modifications in human brain microvascular networks, such as capillary rarefaction. Such modifications limit blood and oxygen supply to the cortex, possibly resulting in energy failure and neuronal death. Modelling is key in understanding how these architectural modifications affect blood flow and mass transfers in such complex networks. However, the huge number of vessels in the human brain—tens of billions—prevents any modelling approach with an explicit architectural representation down to the scale of the capillaries. Here, we introduce a hybrid approach to model blood flow at larger scale in the brain microcirculation, based on its multiscale architecture. The capillary bed, which is a space-filling network, is treated as a porous medium and modelled using a homogenized continuum approach. The larger arteriolar and venular trees, which cannot be homogenized because of their fractal-like nature, are treated as a network of interconnected tubes with a detailed representation of their spatial organization. The main contribution of this work is to devise a proper coupling model at the interface between these two components. This model is based on analytical approximations of the pressure field that capture the strong pressure gradients building up in the capillaries connected to arterioles or venules. We evaluate the accuracy of this model for both very simple architectures with one arteriole and/or one venule and for more complex ones, with anatomically realistic tree-like vessels displaying a large number of coupling sites. We show that the hybrid model is very accurate in describing blood flow at large scales and further yields a significant computational gain by comparison with a classical network approach. It is therefore an important step towards large scale simulations of cerebral blood flow and lays the groundwork for introducing additional levels of complexity in the future.

A study on knowledge based e-learning in teaching learning process

The fast increase in the development in Information and Communication Technology (ICT), a new era comes in the education system. To survive in today's world, the life time learning is very much important with a new cognitive strategy forever. Electronic learning or E-Learning is a kind of skill that supported in the recent teaching learning system. E-Learning refers to anytime any where learning and the medium of education is through computer technology. It also plays the major role in business and corporate industry. The purpose of the learning system is to develop quality of learning. The various learning style will helps to increase the learner's performance. The learning styles of the learner are identified through their behavioural characteristics and cognitive skills. The main objective of the E-learning is to offer the communication platform for teaching learning process. Intelligent Tutoring System (ITS) is an interdisciplinary field that examines to provide instruction to the needs of learner and tutors. This paper aims to develop the knowledge based E-learning by incorporating ITS in Teaching Learning Process. The knowledge based E-Learning system will identify the cognitive level of the learner to understand the concept in better way.
Extracellular YB-1 Blockade in Experimental Nephritis Upregulates Notch-3 Receptor Expression and Signaling

Background: Notch receptors are involved in kidney development and pathogenesis of inflammatory glomerular diseases. Given the secretion of Y-box (YB) protein-1 following cytokine stimulation and subsequent extracellular association with membrane receptor Notch-3 in vitro, we elucidated functional effects of YB-1 targeting on the Notch-3 signaling pathway. Methods: Rat mesangial cells were challenged with a monoclonal anti-YB-1 antibody (YB-1-mAb) and analyzed for YB-1 and Notch-3 expression. Notch-3 expression in mice with a targeted disruption of one YB-1 allele (YB-1+/d) was compared with their wild-type littermates. Furthermore, YB-1-mAb was applied during mesangioproliferative anti-Thy1.1 nephritis, and glomerular Notch-3, Notch target genes and YB-1 expression were analyzed by immunohistochemistry, quantitative real-time PCR and immunoblotting. Results: Upon challenge with YB-1-mAb, rat mesangial cells showed an increased expression of YB-1 and Notch-3 protein. Concordantly, we found a significant upregulation of Notch-3 expression in renal cells of YB-1+/d mice. YB-1-mAb treatment in anti-Thy1.1 nephritis resulted in enhanced mesangial Notch-3 expression and differential Notch target gene activation (HES2/Hey-2). Notably, YB-1 mRNA content did not differ between groups; however, glomerular YB-1 protein was significantly increased, suggesting a posttranslational mechanism. Conclusion: Extracellular targeting of YB-1 potently induces glomerular Notch-3 receptor expression, Notch signaling and YB-1 stabilization, most likely via an autoregulatory feedback mechanism.
Expression of amphiregulin and epidermal growth factor receptor in human breast cancer: analysis of autocriny and stromal–epithelial interactions

Amphiregulin (AR) and its receptor, epidermal growth factor receptor (EGFR), were evaluated by dual immunostaining in a series of 84 invasive ductal breast carcinoma specimens, 33 of which were from locally advanced inflammatory (T4d) cancer. Co‐expression of AR and EGFR was always found in non‐malignant breast tissues adjacent to tumours (24/24). Alternatively, expression of AR and EGFR was found in invasive epithelial tumour cells in 50% and 17.8% of specimens, respectively. In tumour stroma, 59.5% and 30.9% of specimens, respectively, were positively stained. By univariate analysis, AR and EGFR expression in invasive carcinomas was correlated with large tumour size, inflammatory carcinoma, node involvement, Bloom–Richardson (SBR) grade III, and absence of oestrogen receptor. EGFR expression in stromal cells was correlated with non‐inflammatory carcinoma. A putative autocrine loop with AR and EGFR expression in invasive carcinoma was detected in 14.3% of cases. Stromal expression of AR and EGFR expression in invasive tumour cells was detected in 11.9% of cases and related to poor prognostic parameters. By multivariate analysis, AR expression in invasive tumour was strongly related to inflammatory carcinoma (p=0.005) and marginally related to SBR grade III (p=0.07). EGFR expression in invasive tumour and stromal cells was correlated with absence of oestrogen receptor and non‐inflammatory carcinoma (p=0.002 and p=0.015, respectively).

Vocal Tract Length Normalization factor based speaker-cluster UBM for speaker verification

In speaker verification task requires some sort of background model for the system to make decision. Most of the cases, a speaker independent large Gaussian Universal Background Model (GMM-UBM) is used. In this paper, we propose to use a Speaker Cluster-wise UBM (SC-UBM) for a group of target speakers. In this method, the target speakers are clustered into group based on their similarity in Vocal Tract Length Normalization (VTLN) parameter. The VTLN parameter depends on the physiological structure of human speech production system. Hence, the group of speakers with same VTLN factor represent a speaker with unique characteristic. The SC-UBMs are derived from GMM-UBM with Maximum Likelihood Linear Regression (MLLR) by pooling data from the specific group of target speakers. The speaker dependent models are then adapted from their respective SC-UBM using Maximum a Posteriori (MAP) method. During verification, the log likelihood ratio for the claimant is calculated with respect to the corresponding group specific UBM. The comparative study are performed on NIST 2004 SRE in core condition. The SC-UBM system reduced equal error rate (EER) by 9% over the GMM-UBM system.
Compressed Sensing Reconstruction Algorithms with Prior Information: Logit Weight Simultaneous Orthogonal Matching Pursuit

Prior information is easily obtained in many applications of compressed sensing. This paper considers the sparse signal recovery using certain types of prior information. Our major contribution is proposing two novel reconstruction algorithms with prior information named as logit weight simultaneous orthogonal matching pursuit (LW-SOMP) and logit weight simultaneous orthogonal matching pursuit with amplitude information (LW-SOMP-A) for joint sparsity model of distributed compressed sensing. Simulation results demonstrate improved performance of the proposed algorithms (with respect to the conventional algorithm).
Release of oxytocin and vasopressin by magnocellular nuclei in vitro: specific facilitatory effect of oxytocin on its own release.

The release of endogenous oxytocin and vasopressin by rat paraventricular and supraoptic nuclei in vitro during a 10-min period, 30 min after beginning the incubation, was measured radioimmunologically. Mean basal hormone release per 10 min and per pair of nuclei was: 128.4 +/- 12.4 (S.E.M.) pg vasopressin (n = 15) and 39.0 +/- 3.0 pg oxytocin (n = 66) for supraoptic nuclei from male rats; 273.9 +/- 42.6 pg vasopressin (n = 11) and 34.2 +/- 3.5 pg oxytocin (n = 15) for supraoptic nuclei from lactating rats; 70.0 +/- 8.6 pg vasopressin (n = 52) and 21.8 +/- 1.3 pg oxytocin (n = 68) for paraventricular nuclei from male rats; 59.1 +/- 8.6 pg vasopressin (n = 10) and 27.0 +/- 4.6 pg oxytocin (n = 16) for paraventricular nuclei from lactating rats. In male and lactating rats, both nuclei contained and released more vasopressin than oxytocin. For oxytocin alone, the paraventricular nucleus of male rats contained and released significantly less hormone than the supraoptic nucleus. This difference was not apparent in lactating rats. For vasopressin alone, the paraventricular nucleus contained and released significantly less hormone than the supraoptic nucleus in both male and lactating rats. When the hormone released was calculated as a percentage of the total tissue content the release was about 0.9% for oxytocin from both nuclei in male and lactating rats and also for vasopressin in lactating rats, but was only about 0.5% for vasopressin from both nuclei in male rats. The influence of oxytocin and analogues of oxytocin (including one antagonist) upon the release of oxytocin and vasopressin was studied. Adding oxytocin to the incubation medium (0.4-4 nmol/1 solution) induced a dose-dependent rise in oxytocin release from both nuclei of male or lactating rats. A 4 nmol/l solution of isotocin had a similar effect to a 0.4 nmol/l solution of oxytocin, but arginine-vasopressin never affected basal release of oxytocin. In no case was vasopressin release modified. An oxytocin antagonist (1 mumol/l solution) significantly reduced basal oxytocin release and blocked the stimulatory effect normally induced by exogenous oxytocin, as did gallopamil hydrochloride (D600, 10 mumol/l solution), a Ca2+ channel blocker, or incubation in a Ca2+-free medium. These findings are discussed in relation to the literature on the central effects of neurohypophysial peptides. It may be concluded that the regulatory role of endogenous oxytocin in the hypothalamus on the milk-ejection reflex could result from its local release in the extracellular spaces of magnocellular nuclei.
