Dynamics on abelian varieties in positive characteristic
Year: 2018

We study periodic points for endomorphisms \sigma$ of abelian varieties $A$ over algebraically closed fields of positive characteristic $p$ We show that the dynamical zeta function \zeta_\sigma$ of \sigma$ is either rational or transcendental, the first case happening precisely when \sigma^n 1$ is a separable isogeny for all $n$ We call this condition very inseparability and show it is equivalent to the action of \sigma$ on the local $p$ torsion group scheme being nilpotent. The "false" zeta function $D_\sigma$ in which the number of fixed points of \sigma^n$ is replaced by the degree of \sigma^n 1$ is always a rational function. Let $1/\Lambda$ denote its largest real pole and assume no other pole or zero has the same absolute value. Then, using a general dichotomy result for power series proven by Royals and Ward in the appendix, we find that \zeta_\sigma(z) has a natural boundary at |z|=1/\Lambda$ when \sigma$ is not very inseparable. We introduce and study tame dynamics, ignoring orbits whose order is divisible by $p$ We construct a tame zeta function \zeta^*_{\sigma} that is always algebraic, and such that \zeta_\sigma$ factors into an infinite product of tame zeta functions. We briefly discuss functional equations. Finally, we study the length distribution of orbits and tame orbits. Orbits of very inseparable endomorphisms distribute like those of Axiom A systems with entropy \log \Lambda$ but the orbit length distribution of not very inseparable endomorphisms is more erratic and similar to $S$ integer dynamical systems. We provide an expression for the prime orbit counting function in which the error term displays a power saving depending on the largest real part of a zero of $D_\sigma(\Lambda^ s}
Wnt signaling pathway in development and cancer.
Venue: Journal of physiology and pharmacology an official journal of the Polish Physiological Society
Year: 2018

Wnt signaling pathway is one of the most important signaling pathways. The complexity of Wnt signals and their functional role is crucial in development and growth. It is the most active during embryogenesis facilitating new organism formation by cell differentiation, polarization and migration. Its activation is also common during development of many tumors and others diseases. In this review we shortly describe a role of Wnt pathway in development in order to better understand its role in cancer progression. We also describe current anti cancer therapies targeting Wnt pathway.
The primary health care system in China
Venue: The Lancet
Year: 2017

China has made remarkable progress in strengthening its primary health care system. Nevertheless, the system still faces challenges in structural characteristics, incentives and policies, and quality of care, all of which diminish its preparedness to care for a fifth of the world's population, which is ageing and which has a growing prevalence of chronic non communicable disease. These challenges include inadequate education and qualifications of its workforce, ageing and turnover of village doctors, fragmented health information technology systems, a paucity of digital data on everyday clinical practice, financial subsidies and incentives that do not encourage cost savings and good performance, insurance policies that hamper the efficiency of care delivery, an insufficient quality measurement and improvement system, and poor performance in the control of risk factors (such as hypertension and diabetes) As China deepens its health care reform, it has the opportunity to build an integrated, cooperative primary health care system, generating knowledge from practice that can support improvements, and bolstered by evidence based performance indicators and incentives.
CT Based Anatomical Evaluation of Pre Vertebral Structures With Respect to Vertebral Body Using a Clock Face Analogy
Venue: Spine
Year: 2015

Retrospective Chart and CT  To define the relationship of the pre vertebral structures for each level to assist in easier intraoperative visualization.  Vascular and visceral injuries from pedicle screws are well known. This study will define the relationship of the pre vertebral structures for each level to assist in avoiding potential complications.  Pre and post operative CT scans were reviewed to define the pre vertebral structures in relation to a clock face. On reformatted axial slices, a clock face was superimposed so that the left transverse process (TP) represented 8 o'clock and the right TP represented 4 o'clock. The positions of the TP on the clock face did not change with rotation of the vertebra.  108 patients had pre operative CT scans. 78 had post operative CT scans. Median age was 15 years, median Cobb angle was 50deg, fused were 12, with 21 fixation points. 6324 axial CT slices were reformatted and analyzed. The trachea was located at 12 o'clock at T1, 1 o'clock at T2 T4, and between 12 and 1 o'clock at T5. The esophagus starts as a midline structure at 12 o'clock from T1 T2, moves to 11 o'clock from T3 T6, and further to 10 o'clock from T7 T9. The aorta starts at 10 o'clock at T5 T6, moves left at T7 T8 to 9 o'clock, and returns to 10 o'clock from T9 T11. It appears at 11'clock at T12, and at 12 o'clock from L1 L4. In about a third of cases, it is at 1 o'clock from L1 to L4, where it bifurcates.  This CT based anatomical study provides a simple reference frame to help surgeons visualize the vital structures at each level. This three dimensional visualization is facilitated by fixing the position of TP on the clock face. Knowledge of this anatomical relationship can help avoid direct injury, and is easier to recall intra operatively.
SVM Based Speaker Verification using a GMM Supervector Kernel and NAP Variability Compensation
Venue: 2006 IEEE International Conference on Acoustics Speech and Signal Processing Proceedings
Year: 2006

Gaussian mixture models with universal backgrounds (UBMs) have become the standard method for speaker recognition. Typically, a speaker model is constructed by MAP adaptation of the means of the UBM. A GMM supervector is constructed by stacking the means of the adapted mixture components. A recent discovery is that latent factor analysis of this GMM supervector is an effective method for variability compensation. We consider this GMM supervector in the context of support vector machines. We construct a support vector machine kernel using the GMM supervector. We show similarities based on this kernel between the method of SVM nuisance attribute projection (NAP) and the recent results in latent factor analysis. Experiments on a NIST SRE 2005 corpus demonstrate the effectiveness of the new technique

Graphs are among the most ubiquitous models of both natural and human made structures. They can be used to model many types of relations and process dynamics in computer science, physical, biological and social systems. Many problems of practical interest can be represented by graphs. In general graphs theory has a wide range of applications in diverse fields. This paper explores different elements involved in graph theory including graph representations using computer systems and graph theoretic data structures such as list structure and matrix structure. The emphasis of this paper is on graph applications in computer science. To demonstrate the importance of graph theory in computer science, this article addresses most common applications for graph theory in computer science. These applications are presented especially to project the idea of graph theory and to demonstrate its importance in computer science.
Predicting Head Movement in Panoramic Video: A Deep Reinforcement Learning Approach
Venue: IEEE Transactions on Pattern Analysis and Machine Intelligence
Year: 2019

Panoramic video provides immersive and interactive experience by enabling humans to control the field of view (FoV) through head movement (HM) Thus, HM plays a key role in modeling human attention on panoramic video. This paper establishes a database collecting subjects' HM in panoramic video sequences. From this database, we find that the HM data are highly consistent across subjects. Furthermore, we find that deep reinforcement learning (DRL) can be applied to predict HM positions, via maximizing the reward of imitating human HM scanpaths through the agent's actions. Based on our findings, we propose a DRL based HM prediction (DHP) approach with offline and online versions, called offline DHP and online DHP. In offline DHP, multiple DRL workflows are run to determine potential HM positions at each panoramic frame. Then, a heat map of the potential HM positions, named the HM map, is generated as the output of offline DHP. In online DHP, the next HM position of one subject is estimated given the currently observed HM position, which is achieved by developing a DRL algorithm upon the learned offline DHP model. Finally, the experiments validate that our approach is effective in both offline and online prediction of HM positions for panoramic video, and that the learned offline DHP model can improve the performance of online DHP.

DeepHandsVR: Hand Interface Using Deep Learning in Immersive Virtual Reality
Year: 2020

This paper proposes a hand interface through a novel deep learning that provides easy and realistic interactions with hands in immersive virtual reality. The proposed interface is designed to provide a real to virtual direct hand interface using a controller to map a real hand gesture to a virtual hand in an easy and simple structure. In addition, a gesture to action interface that expresses the process of gesture to action in real time without the necessity of a graphical user interface (GUI) used in existing interactive applications is proposed. This interface uses the method of applying image classification training process of capturing a 3D virtual hand gesture model as a 2D image using a deep learning model, convolutional neural network (CNN) The key objective of this process is to provide users with intuitive and realistic interactions that feature convenient operation in immersive virtual reality. To achieve this, an application that can compare and analyze the proposed interface and the existing GUI was developed. Next, a survey experiment was conducted to statistically analyze and evaluate the positive effects on the sense of presence through user satisfaction with the interface experience.
Organizational Capabilities, Strategic Management Accounting and Firm Performance
Year: 2017

From a resource based view perspective, the paper provides empirical evidence on new emerging strategic management accounting (SMA) its association with organizational capabilities (market orientation, entrepreneurship, innovativeness and organizational learning) and the interlinkages among these four elements of organizational capabilities. Partial least squares (PLS) technique was used to test the contingency model. Using the mail survey data of 103 manufacturing strategic business units (SBUs) of public listed companies in Malaysia, the results found that the four organizational capabilities market orientation, entrepreneurship, innovativeness and organizational learning collectively give rise to positional advantage leading to enhanced firm performance. SMA techniques are found to support the internal organizational capabilities. However, SMA usage is not associated with firm performance, indicating that the mediation role of SMA usage on the relationship between organizational capabilities and firm performance is not supported. The results confirm that a firm can attain above average performance if it possesses and emphasizes the four organizational capabilities collectively and these four organizational capabilities collectively are also important to support the usage of SMA techniques which can provide useful information for improvement of internal capabilities as well as resource allocation and utilization.
Die Sektoruntersuchung zum elektronischen Handel
Year: 2017

Am 10.05.2017 hat die Europaische Kommission die Sektoruntersuchung zum elektronischen Handel mit der Veroffentlichung ihres Abschlussberichts abgeschlossen. In diesem gibt sie die wesentlichen Erkenntnisse ihrer Untersuchung wieder. Bei den Verbrauchsgutern fuhrt der Onlinehandel zu einer hoheren Transparenz der Preise und damit zu intensiverem Preiswettbewerb. Dies vereinfacht es Unternehmen, die Endverkaufspreise zu uberwachen, wofur zunehmend spezielle Preissoftware verwendet wird. Das Wachstum des Onlinehandels hat erhebliche Auswirkungen auf die Vertriebsstrategien der Hersteller, die darauf mit einer verstarkten Kontrolle des Vertriebs reagieren. Neben dem Selektivvertrieb und dem direkten Verkauf an Endkunden greifen Hersteller zunehmend auf vertikale Beschrankungen zuruck, die im Widerspruch zu den Bestimmungen des EU Wettbewerbsrechts stehen konnen. Im Bereich der digitalen Inhalte ist die Verfugbarkeit der Rechte an Inhalten von zentraler Bedeutung fur den Wettbewerb. Einige Lizenzierungspraktiken konnen aus Sicht der Kommission eine nahere Uberprufung erfordern. Eine vorzeitige Uberarbeitung des Regelungsrahmens fur vertikale Vereinbarungen wird nicht als erforderlich angesehen. Die in diesem Jahr eroffneten Verfahren lassen jedoch erwarten, dass die Kommission einen starkeren Fokus auf vertikale Beschrankungen legen wird, insbesondere solche, die sich auf den Binnenmarkt auswirken.The e commerce sector inquiryOn 10 May 2017, the European Commission concluded its e commerce sector inquiry with the publication of a final report which contains the main findings of the inquiry. As regards consumer goods e commerce has led to an increased transparency of prices and price competition. Companies can now easily monitor resale prices and increasingly use specific pricing software for this purpose. The growth of e commerce also has significant repercussions on the distribution strategies of manufacturers, which seek a tighter control over distribution activities, inter alia by increasingly using selective distribution and by selling directly to consumers in their own online shops. This desire also leads to more recourse to vertical restraints which may be in conflict with EU competition rules. In the field of digital content, the availability of the relevant content rights is a key determinant for competition. The Commission considers that some licensing practices may require closer scrutiny. An early review of the regulatory framework applicable to vertical agreements is not considered necessary. The proceedings opened this year indicate, however, that the Commission will increase its focus on vertical restraints, in particular those affecting the internal market.
Multi objective optimization of water jet guided laser micro drilling on Inconel 718 using Taguchi Method
Year: 2020

Water jet guided laser overcomes the adverse effects of conventional laser cutting and drilling processes, such as heat affected zone, spatter, burr formation, etc. Pressurized water in this novel process provides focusing, cooling and cleaning on the cut region, eliminating undesired side effects of the laser. The process is nowadays used in energy and aerospace industries for drilling micro cooling holes on turbine blades made of super alloys. However, more research on the process is required to understand the effects of the variables on cutting time and quality. Optimum conditions differ for various materials and geometries. In this study, a multi objective optimization is performed in terms of process time and taper of the micro holes drilled on Inconel 718, a commonly used material in gas turbines. Taguchi design of experiment and statistical analysis is used to perform the experiments and evaluate the results.
Angelica gigas Nakai extract loaded fast dissolving nanofiber based on poly(vinyl alcohol) and Soluplus for oral cancer therapy.
Venue: International journal of pharmaceutics
Year: 2017

A poly(vinyl alcohol) (PVA) and Soluplus (SP) based nanofiber (NF) mat was fabricated using an electrospinning method for the delivery of Angelica gigas Nakai (AGN) extract (ext) to oral cancers. AGN/SP NF (mean diameter: 75+ 26nm; entrapment efficiency: 84.6+ 18.6% and AGN/PVA/SP NF (mean diameter: 170+ 35nm; entrapment efficiency: 81.0+ 10.1% were fabricated using an electrospinning method. Amorphization of AGN EtOH ext was verified by X ray diffractometry (XRD) analysis during the electrospinning process for the fabrication of NF structures. The AGN/PVA/SP NF group exhibited instant wetting (within 2s) and rapid disintegration (within 3min) properties compared with those in the AGN/PVA NF group, assuring the successful and conventional application of AGN/PVA/SP NF film in the oral cavity without the intake of beverages. After the spontaneous dispersion of NF in the aqueous media, it was converted to nanoparticles with a narrow size distribution. In YD 9 cells (oral squamous cell carcinoma from buccal cheek) the anti proliferation activity was ordered as follows: AGN EtOH ext suspension AGN/PVA NF AGN/PVA/SP NF. All of these findings indicated that AGN/PVA/SP NF can be used as a fast dissolving mat formulation for the therapy of oral cancers.

The relationship between big five personality with work motivation, competitiveness and job satisfaction
Year: 2012

A B ST R A C T In spite of its popularity, the Big Five Personality has been criticized for being too descriptive to provide a theoretical model of personality. The current study aims to investigate the extent to which personality and demographic variables contribute to motivation, competitiveness and job satisfaction as defined by measuring their personality, work motivation and satisfaction. This paper shows that conscientiousness and job status were both significant predictors of job satisfaction. All acknowledgement that individual differences can affect the success of an intervention, may contribute to the design of effective work reorganisation schemes that are better suited to the employees they seek to benefit.  The value of this paper was that it looked at how personality and demographic factors may influence work motivation, level of competitiveness and work satisfaction.
Lapatinib with trastuzumab for HER2 positive early breast cancer (NeoALTTO) a randomised, open label, multicentre, phase 3 trial
Venue: The Lancet
Year: 2012

The anti HER2 monoclonal antibody trastuzumab and the tyrosine kinase inhibitor lapatinib have complementary mechanisms of action and synergistic antitumour activity in models of HER2 overexpressing breast cancer. We argue that the two anti HER2 agents given together would be better than single agent therapy.  In this parallel groups, randomised, open label, phase 3 study undertaken between Jan 5, 2008, and May 27, 2010, women from 23 countries with HER2 positive primary breast cancer with tumours greater than 2 cm in diameter were randomly assigned to oral lapatinib (1500 mg) intravenous trastuzumab (loading dose 4 mg/kg [DOSAGE ERROR CORRECTED] subsequent doses 2 mg/kg) or lapatinib (1000 mg) plus trastuzumab. Treatment allocation was by stratified, permuted blocks randomisation, with four stratification factors. Anti HER2 therapy alone was given for the first 6 weeks; weekly paclitaxel (80 mg/m(2) was then added to the regimen for a further 12 weeks, before definitive surgery was undertaken. After surgery, patients received adjuvant chemotherapy followed by the same targeted therapy as in the neoadjuvant phase to 52 weeks. The primary endpoint was the rate of pathological complete response (pCR) analysed by intention to treat.  154 patients received lapatinib, 149 trastuzumab, and 152 the combination. pCR rate was significantly higher in the group given lapatinib and trastuzumab (78 of 152 patients [51*3% 95% CI 43*1 59*5] than in the group given trastuzumab alone (44 of 149 patients [29*5% 22*4 37*5] difference 21*1% 9*1 34*2, p=0*0001) We recorded no significant difference in pCR between the lapatinib (38 of 154 patients [24*7% 18*1 32*3] and the trastuzumab (difference 4*8% 17*6 to 8*2, p=0*34) groups. No major cardiac dysfunctions occurred. Frequency of grade 3 diarrhoea was higher with lapatinib (36 patients [23*4% and lapatinib plus trastuzumab (32 [21*1% than with trastuzumab (three [2*0% Similarly, grade 3 liver enzyme alterations were more frequent with lapatinib (27 [17*5% and lapatinib plus trastuzumab (15 [9*9% than with trastuzumab (11 [7*4% INTERPRETATION Dual inhibition of HER2 might be a valid approach to treatment of HER2 positive breast cancer in the neoadjuvant setting.
Investigation of gamma and neutron shielding parameters for borosilicate glasses doped europium oxide for the immobilization of radioactive waste
Venue: Journal of Materials Science: Materials in Electronics
Year: 2020

Eu 3+ doped borosilicate glasses were prepared by the melt quenching method. Optical, physical and nuclear shielding properties of these glasses were studied. The FTIR measurements indicated that the continuous increase of europium concentration helped conversion of [BO 4 to [BO 3 groups. FTIR spectroscopy results were in good agreement with optical band energy gap, density and molar volume values revealing network modifications caused by europium ions in the glass structure. The amorphous natures of the samples were ascertained by XRD studies. Optical properties of the glass samples are studied before and after neutron at room temperature. The absorption spectra of all glasses indicated that there is a decrease in the optical band gap values due to the enhancement of the number of non bridging oxygen (NBO) atoms with the addition of Eu 2 O 3 Nuclear shielding properties of these have been investigated. The mass attenuation coefcients have been calculated using the XCOM program.
