Writing Electronic Devices on Paper with Carbon Nanotube Ink

The normal paper used in any printer is among the cheapest flexible organic materials that exist. We demonstrate that we can print on paper high-frequency circuits tunable with an applied dc voltage. This is possible with the help of an ink containing functionalized carbon nanotubes and water. After the water is evaporated from the paper, the nanotubes remain steadily imprinted on paper, showing a semiconducting behaviour and tunable electrical properties

Generalized Parton Distributions from Hadronic Observables: Zero Skewness

We propose a physically motivated parametrization for the unpolarized generalized parton distributions. At zero value of the skewness variable, $\zeta$, the parametrization is constrained by simultaneously fitting the experimental data on both the nucleon elastic form factors and the deep inelastic structure functions. A rich phenomenology can be addressed based on this parametrization. In particular, we track the behavior of the average: {\it i)} interparton distances as a function of the momentum fraction, $X$, {\it ii)} $X$ as a function of the four-momentum transfer, $t$; and {\it iii)} the intrinsic transverse momentum $k_\perp$ as a function of $X$. We discuss the extension of our parametrization to $\zeta \neq 0$ where additional constraints are provided by higher moments of the generalized parton distributions obtained from {\it ab initio} lattice QCD calculations.Comment: 42 pages, 21 figure

Bactericide ATM's keyboard intelligent systems

زمینه و هدف: آلوده بودن صفحه کلید دستگاه های خودپرداز بانکی و مراجعه فراوان کاربران به آن ها، باعث انتقال باکتری ها به انسان می شود. بنابراین از بین بردن این باکتری ها نقش مهمی در سلامتی انسان دارد. این مطالعه با هدف معرفی و ارزیابی یک سیستم هوشمند باکتری زدایی از صفحه کلید دستگاه های خودپرداز انجام شد. روش بررسی: در این مطالعه تجربی یک سیستم هوشمند ساخته شد که بر اساس خاصیت باکتری کشی پرتوهای فرابنفش عمل می کند. قبل از ارزیابی سیستم هوشمند، نمونه برداری از صفحه کلیدها انجام و تعداد باکتری اشریشیا کلی به عنوان گروه شاهد در نظر گرفته شد. قابلیت فعال شدن خودکار سیستم (پرتودهی یا قطع پرتودهی) بر اساس تعداد مراجعه کاربران، گذشت زمان و قطع تابش در زمان مراجعه کاربر بررسی شد. پس از تابش به مدت 5، 10، 15 و 20 ثانیه از فاصله 10 سانتی متری به صفحه کلید آلوده، مجدداً نمونه برداری صورت گرفت و پس از کشت باکتری ها، شمارش انجام و تعداد باکتری اشریشیا کلی با گروه شاهد مقایسه شد. یافته ها: بررسی عملکردهای مختلف سیستم نشان داد که پرتودهی (یا قطع پرتودهی) بر اساس موارد تعریف شده برای آن، به صورت خودکار انجام می شود. آزمایش های باکتریولوژیکی نشان داد که با تابش پرتو، تعداد باکتری ها به کمتر از یک درصد می رسد و در همه موارد تعداد باکتری زنده مانده با گروه شاهد تفاوت معنی داری نشان می دهد (05/0>P). نتیجه گیری: یکی از روش های مرسوم کاهش آلودگی از صفحه کلید دستگاه های خودپرداز تمیز نمودن دوره ای آن ها با مواد ضد عفونی کننده است که در دراز مدت روشی پرهزینه می باشد. سیستم هوشمند طراحی شده در مطالعه حاضر راهکار مناسبی برای کاهش آلودگی از صفحه کلید این دستگاه ها می باشد

A Physically Based Analytical Modeling of Threshold Voltage Control for Fully-Depleted SOI Double Gate NMOS-PMOS Flexible-FET

In this work, we propose an explicit analytical equation to show the variation of top gate threshold voltage with respect to the JFET bottom gate voltage for a Flexible Threshold Voltage Field Effect Transistor (Flexible-FET) by solving 2-D Poisson's equation with appropriate boundary conditions, incorporating Young's parabolic approximation. The proposed model illustrates excellent match with the experimental results for both n-channel and p-channel 180nm Flexible-FETs. Threshold voltage variation with several important device parameters (oxide and silicon channel thickness, doping concentration) is observed which yields qualitative matching with results obtained from SILVACO simulations.Comment: 4 pages, EIT 2012-IUPUI conferenc

Self Consistent Simulation of C-V Characterization and Ballistic Performance of Double Gate SOI Flexible-FET Incorporating QM Effects

Capacitance-Voltage (C-V) & Ballistic Current- Voltage (I-V) characteristics of Double Gate (DG) Silicon-on- Insulator (SOI) Flexible FETs having sub 35nm dimensions are obtained by self-consistent method using coupled Schrodinger- Poisson solver taking into account the quantum mechanical effects. Although, ATLAS simulations to determine current and other short channel effects in this device have been demonstrated in recent literature, C-V & Ballistic I-V characterizations by using self-consistent method are yet to be reported. C-V characteristic of this device is investigated here with the variation of bottom gate voltage. The depletion to accumulation transition point (i.e. Threshold voltage) of the C-V curve should shift in the positive direction when the bottom gate is negatively biased and our simulation results validate this phenomenon. Ballistic performance of this device has also been studied with the variation of top gate voltage.Comment: 4 pages, ICEDSA 2012 conferenc

Comparative Analysis of V-Akt Murine Thymoma Viral Oncogene Homolog 3 (AKT3) Gene between Cow and Buffalo Reveals Substantial Differences for Mastitis

AKT3 gene is a constituent of the serine/threonine protein kinase family and plays a crucial role in synthesis of milk fats and cholesterol by regulating activity of the sterol regulatory element binding protein (SREBP). AKT3 is highly conserved in mammals and its expression levels during the lactation periods of cattle are markedly increased. AKT3 is highly expressed in the intestine followed by mammary gland and it is also expressed in immune cells. It is involved in the TLR pathways as effectively as proinflammatory cytokines. The aims of this study were to investigate the sequences differences between buffalo and cow. Our results showed that there were substantial differences between buffalo and cow in some exons and noteworthy differences of the gene size in different regions. We also identified the important consensus sequence motifs, variation in 2000 upstream of ATG, substantial difference in the “3′UTR” region, and miRNA association in the buffalo sequences compared with the cow. In addition, genetic analyses, such as gene structure, phylogenetic tree, position of different motifs, and functional domains, were performed to establish their correlation with other species. This may indicate that a buffalo breed has potential resistance to disease, environment changes, and airborne microorganisms and some good production and reproductive traits

Fcc breathing instability in BaBiO_3 from first principles

We present first-principles density-functional calculations using the local density approximation to investigate the structural instability of cubic perovskite BaBiO_3. This material might exhibit charge disproportionation and some evidence thereof has been linked to the appearance of an additional, fourth peak in the experimental IR spectrum. However, our results suggest that the origin of this additional peak can be understood within the picture of a simple structural instability. While the true instability consists of an oxygen-octahedra breathing distortion and a small octahedra rotation, we find that the breathing alone in a fcc-type cell doubling is sufficient to explain the fourth peak in the IR spectrum. Our results show that the oscillator strength of this particular mode is of the same order of magnitude as the other three modes, in agreement with experiment.Comment: submitted to PRB, completely revised version after referee repor
