Presence of Multifractality in High-Energy Nuclear Collisions  [PDF]
M. I. Haque, M. Tariq, Tahir Hussain
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.517183
Abstract: In the present study an attempt is made to examine multifractality in multiparticle production in relativistic nuclear collisions; multifractality is investigated in 14.5 A GeV/c 28Si-nucleus collisions. For this, Gq-moments are calculated and variations of \"\" are looked into. Values of mass exponents, tq, and generalised dimensions, Dq, are obtained. Analysis of multifractal moments reveals that multiplicity fluctuations are of dynamical nature.
AT2 receptor: Its role in obesity associated hypertension
Quaisar Ali* and Tahir Hussain*
International Journal of Clinical Pharmacology & Toxicology (IJCPT) , 2012,
Abstract: The renin-angiotensin system (RAS) is a hormonal cascade that acts together to regulate blood pressure. Angiotensin II (Ang II) is the major octapeptide of RAS and mediates its cellular and physiological actions by acting on AT1 and AT2 receptor. Most of the cellular and physiological actions of Ang II such as cellular growth and proliferation, vasoconstriction, antinatriuresis and increase in blood pressure are mediated via AT1 receptor. The functions associated with the AT2 receptors are less studied, in part, due to its lower expression in adult tissues. However, AT2 receptor has been suggested as functional antagonist of AT1 receptors and thereby opposes the actions of Ang II mediated via AT1 receptor. Thus, the activation of AT2 receptors has been shown to cause vasodilatation, natriuresis and decrease in blood pressure. After the discovery of the AT2 receptor in various parts of the kidney, including in proximal tubules, there has been an interest in establishing a link between the renal AT2 receptor, renal Na-excretion and blood pressure regulation. Earlier, we have reported that activation of renal AT2 receptors increases urinary Na excretion in obese Zucker rats, in part via inhibiting Na+/K+- ATPase (NKA) activity and stimulating nitric oxide/cGMP pathway in the proximal tubules. An impaired pressure natriuresis and increased AT1 receptor function is believed to be the cause of hypertension in obese Zucker rats and other animal models of obesity. In this review, we are focussing on the role of renin angiotensin system especially AT2 receptors in obesity associated hypertension.
Some Aspects of Multiparticle Production in Relativistic Nuclear Collisions  [PDF]
M. I. Haque, M. Tariq, Hushnud Jahan, Tahir Hussain
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.514136
Abstract:

An attempt is made to study various types of multiplicity distributions and multiplicity correlations amongst secondary charged particles produced in 4.5 and 14.5 A GeV/c 28Si-nucleus interactions. The results reveal that multiplicity correlations of the type \"\", where i, j = b, g, s and h with i ≠ j, are linear. The observed multiplicity correlations are nicely fitted by the method of least squares fitting of the type, \"\"

Modelling of Habitat Suitability Index for Muntjac Muntiacus muntjak Using Remote Sensing, GIS and Multiple Logistic Regression
Imam EKWAL,Hussain TAHIR,Mary TAHIR
Journal of Settlements and Spatial Planning , 2012,
Abstract: Habitat degradation and loss has been widely recognized as the main cause for the decline of wildlife population. Evaluating the quality of wildlife habitat can provide essential information for wildlife refuge design and management. The purpose of this study was to produce georeferenced ecological information about suitable habitats available for muntjac, Muntiacus muntjak in Chandoli tiger reserve, India (17° 04' 00" N to 17° 19' 54" N and 73° 40' 43" E to 73° 53' 09" E). Habitats were evaluated using multiple logistic regression integrated with remote sensing and geographic information system. Satellite imageries of LISS-III of IRS-P6 of study area were digitally processed. To generate collateral data topographic maps were analysed in a GIS framework. Layers of different variables such as Landuse land cover, forest density, proximity to disturbances and water resources and a digital terrain model were created from satellite and topographic sheets. These layers along with GPS location of muntjac presence/absence and ―multiple logistic regression (MLR) techniques were integrated in a GIS environment to model habitat suitability index of muntjac. The results indicate that approximately 222.39 km2 (75.4%) of the forest of tiger reserve was least suitable for muntjac, whereas, 29.53 km2 (10.02%) was moderately suitable, 22.12 km2 (7.5%) suitable and 20.70 km2 (7.0%) was highly suitable. The accuracy level of this model was 97.6%. The model can be considered as potent enough to advocate that forests of this area are most appropriate for declaring it as a reserve for muntjac conservation, ultimately to provide prey base for tiger.
Pattern Recognition of Bearing Faults using Smoother Statistical Features
Muhammad Masood Tahir,Ayyaz Hussain
Computer Science , 2015,
Abstract: A pattern recognition (PR) based diagnostic scheme is presented to identify bearing faults, using time domain features. Vibration data is acquired from faulty bearings using a test rig. The features are extracted from the data, and processed prior to utilize in the PR process. The processing involves smoothing of feature distributions. This reduces the undesired impact of vibration randomness on the PR process, and thus enhances the diagnostic accuracy of the model.
2-(4-Bromophenyl)acetohydrazide
Shakeel Ahmad,Abdul Jabbar,Muhammad Tahir Hussain,M. Nawaz Tahir
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812027006
Abstract: In the title compound, C8H9BrN2O, the 1-bromo-4-methylbenzene group and the formic hydrazide moiety [r.m.s. deviations of 0.0129 and 0.0038 ] are oriented at a dihedral angle of 80.66 (11)°. In the crystal, molecules are linked via strong N—H...O hydrogen bonds, leading to the formation of chains in the [010] direction. These chains are linked via weaker N—H...N and N—H...O hydrogen bonds, with R22(7) and R32(7) ring motifs, forming a two-dimensional network parallel to (001).
2-Chlorobenzohydrazide
Shakeel Ahmad,Abdul Jabbar,Muhammad Tahir Hussain,M. Nawaz Tahir
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812012640
Abstract: The asymmetric unit of the the title compound, C7H7ClN2O, contains two molecules in which the chlorophenyl and the formic hydrazide units are almost planar (r.m.s. deviations of 0.0081 and 0.0100 , respectively, in one molecule and 0.0069 and 0.0150 in the other) and are oriented with respect to each other at dihedral angles of 56.8 (2) and 56.9 (2)°. In the crystal, the molecules are consolidated in the form of polymeric chains extending along [010]. R33(10) ring motifs exist due to N—H...O and N—H...N hydrogen bonds.
Popliteal Artery Entrapment Syndrome Presenting with Acute Limb Ischaemia: A Case Report
Ramawad Soobrah,Adam Nawaz,Tahir Hussain
Case Reports in Medicine , 2010, DOI: 10.1155/2010/281925
Abstract: Popliteal artery entrapment syndrome (PAES) is a relatively rare condition that occurs in young patients as a result of anomalous anatomic relationships between the popliteal artery and the surrounding musculotendinous structures. Patients usually lack atherogenic risk factors and most commonly present with intermittent claudication in the early stages. In the later stages of undiagnosed PAES, acute ischaemia can occur as a result of complete arterial occlusion or embolism. Hence, early diagnosis and surgical release of the entrapment is crucial for good operative outcome and to prevent limb loss.

Shea Division of Sleep Medicine, Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA Insomnia is rife. Acutely, almost every individual has experienced a poor night’s sleep, and many short-term remedies for insomnia are tried, including over-the-counter sleep aids and alcohol. Chronic insomnia is the most common sleep disorder, affecting nearly 40 million Americans and accounting for nearly one-third of adults. The annual cost associated with this disorder in the US is estimated at over $15 billion and over $100 billion for indirect costs, such as costs of self-medication, health care-related costs due to exacerbations of comorbid conditions, and costs of reduced productivity.
