Emad Abu Sitta, Nour Aljariri Alhesan, Babikir Kheiri, Sunil Badami, Farah Elounais, Omar Assassa, Maneesh Gaddam, Carlos Rios-Bedoya
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1104043
Background: Severe acute uncomplicated pyelonephritis is an infection of the kidneys that usually have an ascending route and occur in presumably healthy urinary tract. The most common pathogen involved is E. coli. The Infectious Diseases Society of America (IDSA) has issued an updated guideline in 2010 suggesting IV quinolones to be considered in the initial empiric antimicrobial therapy giving known resistance of less than 10%. However, E. coli resistance to quinolones has been increasing, the recent data of E. coli, causing pyelonephritis, resistance is not known in the Midwest. Local hospital antibiogram for two years showed up to 22% resistance to ciprofloxacin among E. coli isolates. Methods: We conduct a retrospective non-concurrent cohort study in one teaching hospital in the Midwest, females who were admitted with severe acute uncomplicated pyelonephritis in a three years period were included. Patients with urinary tract obstruction, pregnancy, immuno-suppression, males, and indwelling Foley’s catheters were excluded. Data collected include causative pathogens and resistance to antibiotics were collected. Percentages, frequencies, and measures of central tendency and dispersion were calculated to describe the study sample Results: 73 patients were included in the final analysis. E. coli was the most common isolated pathogen (81%), followed by other enteric gram negative. E. coli resistance to ciprofloxacin was 13.5%, 37% to trimethoprim-sulfamethoxazole, and 5% to ceftriaxone. Conclusion: Ciprofloxacin should be avoided initially in treating severe acute uncomplicated pyelonephritis until culture results and sensitivity is available.
Entanglement and Quantum Discord of Two Moving Atoms  [PDF]
Nour Zidan
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.516240

In this paper we discuss two measures for the quantumness of correlations (quantum discord and entanglement) of two isolated moving atoms which are initially in Werner state. We compare and analyze the effect of the atomic motion in quantum discord and entanglement. The results show that the atomic motion related to the field mode structure parameter can make the entanglement and quantum discord evolve periodically. The results also indicate that the entanglement suddenly disappears during the evaluation but quantum discord remains non zero, so quantum discord is considered as indicator of disentanglement.

Quantum Discord of a Two-Qubit Anisotropy XXZ Heisenberg Chain with Dzyaloshinskii-Moriya Interaction  [PDF]

Journal of Quantum Information Science (JQIS) , 2014, DOI: 10.4236/jqis.2014.42011

We investigate the quantum discord of a two-qubit anisotropy XXZ Heisenberg chain with Dzyaloshinskii-Moriya (DM) interaction under magnetic field. It is shown that the quantum discord highly depends on the system’s temperature T, DM interaction D, homogenous magnetic field B and the anisotropy Δ. For lower temperature T, by modulating D and B, the quantum discord can be controlled and the quantum discord switch can be realized.

Review: Nitrogen Utilization Features in Cotton Crop  [PDF]
Nour Ali
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.67105
Abstract: Cotton is one of the important cash crops and a fiber crop most widely grown and the highest yielding as well. Cotton fiber is woven to be the fabrics commonly used in our daily life due to its excellent performance and great production in the world, especially in China. To access to such high quantities must ensure the requirements of materials such as nutrients for plant growth and take care of the smallest details to make the production cost less, to improve the utilization efficiency, such as nitrogen (N) fertilizer. Hence, N fertilization studies are not only about the dosages, timing and ratio, but also the uptake processes by the plant, N effect on cotton yield and its formation, as well as the movement and metabolism within the plant. As economic and ecological issues are concerned, economizing N fertilization is paid more and more attention. Many approaches have been done and suggested in order to improve NUE like combine the plant sensing techniques and precision application. Simulations and recent field trials demonstrate that site-specific nitrogen management helped reduce technological constraints to higher AE achievement, profit and more sustainable N management. Therefore, improving nitrogen use efficiency (NUE) is one of the key points to ensure cotton production development sustainable. In this review, we try to highlight the accomplishments of N effect on cotton growth and yield, NUE and factors related to NUE in cotton production based on the current knowledge, and from our viewpoint we propose some possible approaches to improve NUE through N managements in terms of application splits, rates, and timing.
Multi-Resolution Fourier Analysis Part I: Fundamentals  [PDF]
Nourédine Yahya Bey
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.46042
Abstract: In the first paper of this series, we propose a multi-resolution theory of Fourier spectral estimates of finite duration signals. It is shown that multi-resolution capability, achieved without further observation, is obtained by constructing multi-resolution signals from the only observed finite duration signal. Achieved resolutions meet bounds of the uncertainty principle (Heisenberg inequality). In the forthcoming parts of this series, multi-resolution Fourier performances are observed, applied to short signals and extended to time-frequency analysis.
Extraction of Signals Buried in Noise: Non-Ergodic Processes  [PDF]
Nourédine Yahya Bey
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2010, DOI: 10.4236/ijcns.2010.312124
Abstract: In this paper, we propose extraction of signals buried in non-ergodic processes. It is shown that the proposed method extracts signals defined in a non-ergodic framework without averaging or smoothing in the direct time or frequency domain. Extraction is achieved independently of the nature of noise, correlated or not with the signal, colored or white, Gaussian or not, and locations of its spectral extent. Performances of the pro-posed extraction method and comparative results with other methods are demonstrated via experimental Doppler velocimetry measurements.
Extraction of Buried Signals in Noise: Correlated Processes  [PDF]
Nourédine Yahya Bey
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2010, DOI: 10.4236/ijcns.2011.311116
Abstract: In this paper, we propose extraction of signals correlated with noise in which they are buried. Proposed extraction method uses no a-priori information on the buried signal and works independently of the nature of noise, correlated or not with the signal, colored or white, Gaussian or not, and locations of its spectral extent. Extraction of buried correlated signals is achieved without averaging in the time or frequency domain.
Multi-Resolution Fourier Analysis Part II: Missing Signal Recovery and Observation Results  [PDF]
Nourédine Yahya Bey
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2012, DOI: 10.4236/ijcns.2012.51004
Abstract: In this paper, we report application procedures and observed results of multi-resolution Fourier analysis proposed in the first part of this series. Missing signal recovery derived from multi-resolution theory is developed. It is shown that multi-resolution Fourier analysis enhances dramatically performances of Fourier spectra suffering limitations traced to implicit time windowing. Observed frequency resolutions, improvement of frequency estimations, contraction of spectral leakage and recovery of missing parts of finite duration signals are in accordance with theoretical predictions.
Propositional Mixed Logic: Its Syntax and Semantics
Karim Nour,Abir Nour
Mathematics , 2009,
Abstract: In this paper, we present a propositional logic (called mixed logic) containing disjoint copies of minimal, intuitionistic and classical logics. We prove a completeness theorem for this logic with respect to a Kripke semantics. We establish some relations between mixed logic and minimal, intuitionistic and classical logics. We present at the end a sequent calculus version for this logic.
Hand Gesture Recognition Approach for ASL Language Using Hand Extraction Algorithm  [PDF]
Alhussain Akoum, Nour Al Mawla
Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.88041
Abstract: In a general overview, signed language is a technique used for communicational purposes by deaf people. It is a three-dimensional language that relies on visual gestures and moving hand signs that classify letters and words. Gesture recognition has been always a relatively fearful subject that is adherent to the individual on both academic and demonstrative levels. The core objective of this system is to produce a method which can identify detailed humanoid nods and use them to either deliver ones thoughts and feelings, or for device control. This system will stand as an effective replacement for speech, enhancing the individual’s ability to express and intermingle in society. In this paper, we will discuss the different steps used to input, recognize and analyze the hand gestures, transforming them to both written words and audible speech. Each step is an independent algorithm that has its unique variables and conditions.
