The effect of ph adjustments on the structural and optical properties of cias thin films

CIAS, ‘Cu (In Al) Se2’ thin films are prepared on the glass substrates using economical chemical bath deposition ‘CBD’ technique. The effect of pH adjustments before or after preheating the reaction mixture has been discussed in this paper in a detail. Due to pH adjustment the change in the preferential orientation on the structural properties and the band gap variation with respect to thickness on the optical properties, has also been discussed

A rare balanced parental t (21q; 21q) Robertsonian translocation that results in Down syndrome in all viable pregnancies

We report a case of a rare balanced Robertsonian translocation, t (21q; 21q) in one of the parents that results in adverse pregnancy outcome in 100 % of cases, either first trimester miscarriages or Down syndrome in all viable fetuses. The case highlights the role of optimum genetic evaluation of all cases of reproductive disorders as they can have profound effect over prognosis and further management

A case of viable fetus co-existing with a complete hydatidiform mole in a twin pregnancy with successful outcome

Twin pregnancies with a viable fetus and co-existing complete hydatidiform mole (CHMF) are being increasingly reported in literature. It is now evident that with proper obstetric care live births can be reasonably expected. We present here such a case successfully managed at our centre with one year follow up of mother and the baby. The case highlights the role of prompt diagnosis, rational prenatal counselling, evidence based management and role of high risk obstetric and neonatal care in providing solutions to seemingly difficult situations

Rational design of a planar junctionless field-effect transistor for sensing biomolecular interactions

In the ElectroMed project, we are interested in screening certain peptide sequences for their ability to selectively interact with antibodies or MHC proteins. This poses a combinatorial challenge that requires a highly multiplexed setup of label-free immunosensors. Label-free FET-based immunosensors are good candidates due to their high multiplexing capability and fast response time. Nanowire-based FET sensors have shown high sensitivity but are unreliable for clinical applications due to drift and gate stability issues. To address this, a label-free immuno-FET architecture based on planar junctionless FET devices is proposed. This geometry can improve the signal-to-noise ratio due to its larger planar structure, which is less prone to defects that cause noise and is better suited to the functionalization of different receptor molecules

Implicit scheme for meshless compressible Euler solver

In this paper, an implicit scheme is presented for a meshless compressible Euler solver based on the Least Square Kinetic Upwind Method (LSKUM). The Jameson and Yoon’s split flux Jacobians formulation is very popular in finite volume methodology, which leads to a scalar diagonal dominant matrix for an efficient implicit procedure (Jameson & Yoon, 1987). However, this approach leads to a block diagonal matrix when applied to the LSKUM meshless method. The above split flux Jacobian formulation, along with a matrix-free approach, has been adopted to obtain a diagonally dominant, robust and cheap implicit time integration scheme. The efficacy of the scheme is demonstrated by computing 2D flow past a NACA 0012 airfoil under subsonic, transonic and supersonic flow conditions. The results obtained are compared with available experiments and other reliable computational fluid dynamics (CFD) results. The present implicit formulation shows good convergence acceleration over the RK4 explicit procedure. Further, the accuracy and robustness of the scheme in 3D is demonstrated by computing the flow past an ONERA M6 wing and a clipped delta wing with aileron deflection. The computed results show good agreement with wind tunnel experiments and other CFD computations

Systematics and song structure of Prozvenella bangalorensis sp n. with a discussion of song features in Podoscirtini crickets (Orthoptera, Grylloidea, Podoscirtidae)

The systematics of the podoscirtine genus Prozvenella Gorochov, 2001(2002) is reviewed, with the description of one new species, P. bangalorensis sp. n. A diagnosis of all known species of Prozvenella is given and a key for male identification is proposed. The monophyly and relationships of Prozvenella are discussed and the homologies for male genitalic characters in Podoscirtini are re-examined. The calling song of P. bangalorensis is described and examined for its variability. A general schema of song variation in Podoscirtini is discussed with a preliminary appraisal on song evolution in this clade

Multithreaded Architectural Support for Speculative Trace Scheduling in VLIW Processors

VLIW processors are statically scheduled processors and their performance depends on the quality of schedules generated by the compiler's scheduler. We propose a multi-threaded architectural support for speculative trace scheduling in VLIW processors. In this multithreaded architecture the next most probable trace is speculatively executed, overlapping the stall cycles of the processor during cache misses and page faults. Switching between traces is achieved with the help of special hardware units viz. operation state buffers and trace buffers. We observe an 8.39% reduction in the overall misprediction penalty as compared to that incurred when the stall cycles due to cache misses alone are not overlapped
