IRIS AND FINGER VEIN MULTI MODEL RECOGNITION SYSTEM BASED ON SIFT FEATURES
Authors: Mohammed Faris E , ALdaidamony Dr. Eman M , Raid Prof. A. M 
Published: October 2018

Individual identification process is a very significant process that resides a large portion of day by day usages. Identification process is appropriate in work place, private zones, banks …etc. Individuals are rich subject having many characteristics that can be used for recognition purpose such as finger vein, iris, face …etc. Finger vein and iris key-points are considered as one of the most talented biometric authentication techniques for its security and convenience. SIFT is new and talented technique for pattern recognition. However, some shortages exist in many related techniques, such as difficulty of feature loss, feature key extraction, and noise point introduction. In this manuscript a new technique named SIFT-based iris and SIFT-based finger vein identification with normalization and enhancement is proposed for achieving better performance. In evaluation with other SIFT-based iris or SIFT-based finger vein recognition algorithms, the suggested technique can overcome the difficulties of tremendous key-point extraction and exclude the noise points without feature loss. Experimental results demonstrate that the normalization and improvement steps are critical for SIFT-based recognition for iris and finger vein , and the proposed technique can accomplish satisfactory recognition performance. Keywords: SIFT, Iris Recognition, Finger Vein identification and Biometric Systems.

Development and regional planning within the decentralized administrative frame: case study (the Jordanian Experiment)
Authors: Safran Mansour 
Published: October 2018

This aims to review and analyze the Jordanian experiment in the developmental regional planning field within the decentralized managerial methods, which is considered one of the primary basic provisions for applying and success of this kind of planning. The study shoed that Jordan has passed important steps in the way for implanting the decentralized administration, but these steps are still not enough to established the effective and active regional planning. The study reveled that there are many problems facing the decentralized regional planning in Jordan, despite of the clear goals that this planning is trying to achieve. These problems have resulted from the existing relationship between the decentralized administration process’ dimensions from one side, and between its levels which ranged from weak to medium decentralization from the other side, In spite of the official trends aiming at applying more of the decentralized administrative policies, still high portion of these procedures are theoretical, did not yet find a way to reality.
Because any progress or success at the level of applying the decentralized administrative policies doubtless means greater effectiveness and influence on the development regional planning in life of the residents in the kingdom’s different regions. So, it is important to go a head in applying more steps and decentralized administrative procedures, gradually and continuously to guarantee the control over any negative effects that might result from Appling this kind of systems.

Abstract
We present a neutral hydrogen-selected absorption-line survey of gas with H i column densities

at

using the Cosmic Origins Spectrograph on the Hubble Space Telescope. Our main aim is to determine the metallicity distribution of these absorbers. Our sample consists of 224 absorbers selected on the basis of their H i absorption strength. Here we discuss the properties of our survey and the immediate empirical results. We find singly and doubly ionized metal species, and H i typically have similar velocity profiles, implying they probe gas in the same or similar environments. The ionic ratios (e.g.,

/

,

/

) indicate that the gas in these absorbers is largely ionized, and the ionization conditions are quite comparable across the sampled

range. The Doppler parameters of the H i imply

K on average, consistent with the gas being photoionized. The Mg ii column densities span >2 orders of magnitude at any given

, indicating a wide range of metallicities (from solar to <1/100 solar). In the range of

, there is a gap in the

distribution corresponding to gas with ∼10% solar metallicity, consistent with the gap seen in the previously identified bimodal metallicity distribution in this column density regime. Less than 3% of the absorbers in our sample show no detectable metal absorption, implying that truly pristine gas at

Abstract
A validation of the cosmic distance duality (CDD) relation,

) and angular-diameter (d

) distances, is crucial because its violation would require exotic new physics. We present a model-independent test of the CDD, based on strong lensing and a reconstruction of the H ii galaxy Hubble diagram using Gaussian processes, to confirm the validity of the CDD at a very high level of confidence. Using parameterizations

and

, our best-fit results are

, and

and

, respectively. In spite of these strong constraints, however, we also point out that the analysis of strong lensing using a simplified single isothermal sphere (SIS) model for the lens produces some irreducible scatter in the inferred CDD data. The use of an extended SIS approximation, with a power-law density structure, yields very similar results, but does not lessen the scatter due to its larger number of free parameters, which weakens the best-fit constraints. Future work with these strong lenses should therefore be based on more detailed ray-tracing calculations to determine the mass distribution more precisely.
Photopolarimetric Characteristics of Brown Dwarfs. I. Uniform Cloud Decks
Authors: Sanghavi Suniti , Shporer Avi 
Published: October 2018

Abstract
This work is a theoretical exploration facilitating the interpretation of polarimetric observations in terms of cloudiness, rotational velocities, and effective temperatures of brown dwarfs (BDs). An envelope of scatterers like free electrons, atoms/molecules, or haze/clouds affects the Stokes vector of the radiation emitted by oblate bodies. Due to high rotation rates, BDs can be considerably oblate. We present a conics-based radiative transfer scheme for computing the disk-resolved and disk-integrated polarized emission of an oblate BD or extrasolar giant planet bearing homogeneous or patchy clouds. Assuming a uniform gray atmosphere, we theoretically examine the sensitivity of photopolarimetry to the atmosphere’s scattering properties, like cloud optical thickness and grain size, concurrently with BD properties, like oblateness, inclination, and effective temperature, which are all treated as free parameters. Additionally, we examine the potential effects of gravitational darkening (GD), revealing that it could significantly amplify disk-integrated polarization. GD imparts a nonlinear inverse temperature dependence to the resulting polarization. Photopolarimetric observations are sensitive to oblateness and inclination. The degree of polarization increases in response to both, making it potentially useful for assessing the spatial orientation of the BD. Under our model assumptions, increasing droplet size in optically thick clouds causes a blueward shift in the near-infrared colors of BDs, which is interesting in light of the observed J – K brightening in the L/T transition. For large cloud grains, polarization decreases sharply, while the transmitted intensity shows a steady increase. BD polarization is thus a potential indicator not only of the presence of clouds but also provides information on cloud grain size.
Implantable Collamer Lens
®
for Management of Pseudophakic Ametropia in Eyes With a Spectrum of Previous Corneal Surgery
Authors: Alfonso José F. , Lisa Carlos , Alfonso-Bartolozzi Belen , Fernández-Vega-Cueto Luis , Montés-Micó Robert 
Published: October 2018

PURPOSE:
To assess the visual outcomes, predictability, and safety of the Implantable Collamer Lens (ICL) (STAAR Surgical, Inc., Monrovia, CA) for the management of residual pseudophakic refractive error.

METHODS:
Forty-nine pseudophakic eyes of 40 patients in which myopic, hyperopic, or toric ICLs were implanted were retrospectively analyzed. Twenty-nine eyes had been implanted with a monofocal intraocular lens (IOL) and 20 eyes had a multifocal IOL. All IOLs were implanted in the capsular bag. Of the 49 eyes included, 6 had residual refractive error after phacoemulsification without corneal pathology or surgical alteration (virgin cornea group), 12 had LASIK or photorefractive keratectomy (PRK) (excimer laser group), 8 had radial keratotomy, 5 had intrastromal corneal ring segments (ICRS) implantation, 11 had penetrating keratoplasty, and 7 had deep anterior lamellar keratoplasty (DALK). Uncorrected and corrected (CDVA) distance visual acuity and manifest refraction were evaluated.

RESULTS:
The efficacy/safety indices were 0.92/1.10, 0.98/1.13, 1.04/1.11, 0.90/1.13, 0.79/1.17, and 0.71/1.23 for the virgin cornea, excimer laser, radial keratotomy, ICRS, penetrating keratoplasty, and DALK groups, respectively. No eye lost one or more lines of CDVA. The virgin cornea, excimer laser, and radial keratotomy groups showed better predictability and accuracy, with 96.2% spherical equivalent within ±1.00 diopters (D). The ICRS, penetrating keratoplasty, and DALK groups demonstrated approximately 50% spherical equivalent within ±1.00 D. There were no intraoperative or postoperative complications.

CONCLUSIONS:
Good refractive outcomes and a strong safety record support the use of the ICL for the correction of residual refractive error in pseudophakic eyes with previous corneal surgery.

I CHEMIOTERAPICI ANTIVIRALI<sup>1</sup>
Authors: Perno Carlo Federico 
Published: October 2018

The concept of drug development with specific antiviral action is quite recent. The discovery, in the late â€˜70s, that acyclic nucleoside analogs could inhibit the replication of the Herpes Simplex virus (HSV) DNA, was the fundamental step that opened the way to the research on drugs able to deal with diseases caused by viruses. In the â€˜80s, the need to fight another disease related to a virus, AIDS caused by HIV, gave a further boost to the research in the field of viral chemotherapy. Currently, several classes of drugs are available for the treatment of viruses such as influenza virus, respiratory syncytial virus, herpes simplex virus, varicella-zoster virus, HBV and hepatitis viruses, cytomegalovirus and HIV. Nevertheless, we however need a continuous and progressive development of antiviral chemotherapy and of the research related to it that can cope with the problem of the effectiveness of antiviral vaccines, the emergence of new diseases related to immunosuppression. In this context, the research of professor Paolo Mantegazza has made a valuable contribution to the understanding of the transforming role of some viruses such as polyomaviruses, including the SV40 monkey vacuolar virus. Professor Mantegazza also made a significant contribution to the synthesis of compounds for transmissible spongiform encephalopathies caused by prions.

Conventional and advanced brain MR imaging in patients with sickle cell anemia
Authors: Issar Pratibha , Nehra Maya , Singh Gurmeet , Issar SK 
Published: October 2018

Abstract
Background: Sickle cell disease (SCD) is an autosomal recessive hemolytic disorder; its cerebrovascular complications include silent cerebral ischemia, infarct, and brain atrophy. Conventional magnetic resonance imaging (MRI) often underestimates the extent of injury. Diffusion tensor imaging (DTI) can demonstrate and quantify microstructural brain changes in SCD cases having normal routine MRI. Objective: To identify various neurological abnormalities in asymptomatic sickle cell patients using routine MRI and to evaluate the microstructure of various regions of the brain using DTI. Materials and Methods: A prospective, randomized case–control study was conducted over a period of 2 years. A total of 58 cases of SCD and 56 age- and sex-matched controls were included. Routine MRI and DTI were performed in both the groups following a standard protocol. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were calculated in certain pre-defined regions. Primary data were analyzed using MS excel version 17. Analysis of variance test was performed and statistical significance was set at P < 0.05. Results: Thirty regions of interest with 60 variables were included in the final analysis. Patients with SCD showed statistically significant reduced FA values, increased ADC values, or both, clustered in several brain areas, including pons, cerebral peduncle, corpus callosum, frontal, temporal, parietal white matter, centrum semiovale, periventricular areas, basal ganglia, and left thalamus (P < 0.05). Conclusion: DTI is a promising method for characterizing microstructural changes, when conventional MRI is normal.
Plain CT vs MR venography in acute cerebral venous sinus thrombosis: Triumphant dark horse
Authors: Digge Poornima , Prakashini Koteshwar , Bharath K V 
Published: October 2018

Abstract
Context: Most patients with cerebral venous sinus thrombosis (CVST) present with nonspecific signs and symptoms and are likely to undergo nonenhanced head computed tomography (NCT) at presentation, which may show a normal report in up to two-thirds of patients. However, in case of acute thrombosis, sensitivity of diagnosing CVST is high as sinuses are hyperdense. Though magnetic resonance imaging (MRI) is considered the imaging modality of choice for diagnosing CVST, it is not universally available in an acute setting. Aims: To evaluate whether increased attenuation in cerebral venous sinuses in acute condition can be used to diagnose acute CVST and to determine its diagnostic value. Materials and Methods: The study involves two independent groups. One group of patients with sinus thrombosis were confirmed by MR venography (group A). The other group included patients without sinus thrombosis (group B). The HU (CT attenuation), hemoglobin (HGB), hematocrit (HCT), and H: H (HU: HCT) ratio of both groups were compared. Thirty-six patients (59 thrombotic sinuses) were studied in group A and 40 in group B. Statistical Analysis: Average HU and H: H ratio were compared using two-tailed t-test, and linear regression analysis was used to assess correlation between HCT and HU. Results: Average HU (73.7 vs 48.6) and H: H ratio values were higher in group A patients compared to group B (P < 0.05). Linear regression analysis showed positive correlation between HGB and HCT with HU among both the groups (P < 0.05). Conclusions: Our study demonstrates that acute CVST can be diagnosed using HU values in NCT.
Bronchial anthracofibrosis: The spectrum of radiological appearances
Authors: Shah Ashok , Kunal Shekhar , Gothi Rajesh 
Published: October 2018

AbstractBronchial anthracofibrosis (BAF), caused by long-standing exposure to biomass fuel smoke, has emerged as a distinct pulmonary disease. It is usually seen in elderly females who have worked long hours in poorly ventilated kitchen full of smoke due to incomplete combustion of biomass fuel. The diagnosis is confirmed on bronchoscopic visualization of bluish-black anthracotic pigmentation along with narrowing/distortion of the affected bronchus. BAF has been associated with clinical conditions such as pulmonary tuberculosis, chronic obstructive pulmonary disease, pneumonia, and malignancy. Tuberculosis, once thought to be the causative agent for BAF, is now considered to be an association. BAF has a diverse radiological presentation and the presence of associated clinical conditions often confound the radiological picture. The imaging features of BAF include primary imaging characteristics, which pertains to the disease entity directly, and secondary features based on the presence of associated conditions. High-resolution computed tomography findings of multifocal bronchial narrowing and peribronchial cuffing are considered to be specific diagnostic features of BAF. In addition, the diagnostic probability is increased in the presence of mediastinal adenopathy and collapse/atelectasis with middle lobe syndrome being the most common presentation. This pictorial essay highlights the range of imaging appearances in patients with BAF.

Published: October 2018

AbstractMost mucinous cystadenomas of pancreas are solitary and multilocular with a few large compartments. Serous cystadenomas usually have a polycystic or microcystic (honeycomb) pattern consisting of collection of cysts (usually >6) that range from few millimetres up to 2 cm in size. Here we present a case of mucinous cystadenoma of pancreas showing an unusual appearance of honeycombing (which has not been described so far) using imaging studies such as endoscopic ultrasound and computed tomography with histopathological confirmation of the diagnosis.
