Structure of p300 bound to MEF2 on DNA reveals a mechanism of enhanceosome assembly (2011)

Transcription co-activators CBP and p300 are recruited by sequence-specific transcription factors to specific genomic loci to control gene expression. A highly conserved domain in CBP/p300, the TAZ2 domain, mediates direct interaction with a variety of transcription factors including the myocyte enhancer factor 2 (MEF2). Here we report the crystal structure of a ternary complex of the p300 TAZ2 domain bound to MEF2 on DNA at 2.2Å resolution. The structure reveals three MEF2:DNA complexes binding to different sites of the TAZ2 domain. Using structure-guided mutations and a mammalian two-hybrid assay, we show that all three interfaces contribute to the binding of MEF2 to p300, suggesting that p300 may use one of the three interfaces to interact with MEF2 in different cellular contexts and that one p300 can bind three MEF2:DNA complexes simultaneously. These studies, together with previously characterized TAZ2 complexes bound to different transcription factors, demonstrate the potency and versatility of TAZ2 in protein-protein interactions. Our results also support a model wherein p300 promotes the assembly of a higher-order enhanceosome by simultaneous interactions with multiple DNA-bound transcription factors.
Measuring nanomechanical motion with a microwave cavity interferometer (2008)

In recent years microfabricated microwave cavities have been extremely successful in a wide variety of detector applications. In this article we focus this technology on the challenge of quantum-limited displacement detection of a macroscopic object. We measure the displacement of a nanomechanical beam by capacitively coupling its position to the resonant frequency of a superconducting transmission-line microwave cavity. With our device we realize near state-of-the-art mechanical force sensitivity (3 $\rm{aN/\sqrt{Hz}}$) and thus add to only a handful of techniques able to measure thermomechanical motion at 10's of milliKelvin temperatures. Our measurement imprecision reaches a promising 30 times the expected imprecision at the standard quantum limit, and we quantify our ability to extract measurement backaction from our results as well as elucidate the important steps that will be required to progress towards the full quantum limit with this new detector.
Combination Nonviral Interleukin 2 and Interleukin 12 Gene Therapy for Head and Neck Squamous Cell Carcinoma (2001)

The nonviral gene delivery system was well tolerated, and combined mIL-2 and mIL-12 gene transfer generated potent antitumor immune responses against HNSCC in our murine model. Combined nonviral IL-2 and IL-12 gene therapy may have great potential as a primary or adjuvant treatment for HNSCC in humans.
Effective Handling of Low Memory Scenarios in Android using Logs (2013)

Android memory management unit also plays vital role in great success of android among other operating systems. Memory is a very limited resource especially in embedded systems like phones and tablets. Android contains modified Linux kernel for handling low memory scenarios and other issues. Out Of Memory (OOM) killer in linux kills some of the processes in low memory scenarios. This report gives details on different set of problems in OOM killer. Activity Manager Service(AMS), Low Memory Killer(LMK) in android kills some of the applications in low memory scenarios along with OOM killer. In low memory scenarios we should not kill user interesting or user frequently accessing applications. If we kill any user frequently accessing applications, then we need to load those applications, if user wants to access those applications in future. Load operation is costly, it takes nearly 3-5 sec to load an application, as it varies from one application to others. So if we can predict user interesting or future accessing applications using user log history, we can reduce number of applications gets killed in a period of time. We developed AppsLogger application, which predicts the user interesting applications using log history. We modified traditional AMS source code in android 4.2, such that AMS do not kills user interesting applications received from AppsLogger. We are succeeded to reduce x% number of application gets killed in a period of time using log history as compared with traditional approach. We are succeeded to reduce avg response time of accessing any application as y% , z% in log based exponential,linear approaches as compared with traditional android approach.
Effects of type of polymerization catalyst system on the degradation of polyethylenes in the melt state. Part 1: Unstabilized polyethylenes (including metallocene types) (2011)

Abstract Several polyethylene resins namely, high‐density polyethylene (HDPE) (Phillips metal oxide catalyst) and linear low‐density polyethylenes (LLDPE) (formed by using Ziegler‐Natta and metallocene catalyst technologies), were used in order to acquire insight into the effect of different polymerization catalyst systems on the production of degradation products during melt processing. Infrared spectroscopy, color measurement, hydroperoxide determination, and melt flow rate measurement were used to monitor the degradation as a function of the number of passes through a twin‐screw extruder. The metallocene PEs were shown to exhibit superior melt stability relative to Phillips HDPE. The latter showed high levels of hydroperoxide formation. The superior thermo‐oxidative stability of the metallocene PEs was attributed to low levels of metallic catalyst residues, together with low vinyl unsaturation content. In all of the PEs examined, the rate of crosslinking was greater than that of chain scission. IR spectroscopy indicated that crosslinking (most prevalent in the Phillips HDPE) proceeded via the addition of macroradicals to vinyl unsaturation. The Ziegler‐Natta LLDPE showed an intermediate tendency for crosslinking but notable formation of trans ‐vinylidene and the most noticeable color development. J. VINYL ADDIT.

Design and implementation for 125 mW/MIPS ultra-high speed low power asymmetric digital subscriber line transceiver chip (2003)

Multimedia service with audio and video have become most desirable as the ADSL technology ideally converted from 1.5 Mbps full duplex HDSL technology via two twist-pair into 6.144 Mbps transmission technology via single twist-pair. This results in an interactive transmission service of T1 & E1 class data using the subscriber line without repeaters. The ADSL transceiver chipset is configured by DMT (Discrete Multi Tone modulation) scheme and RISC-based DSP core structure. Our ADSL chip is to be used in VOD, interactive interact service and/or teleconferencing system, etc. The operating frequency and dissipated power of the chip are 40 MHz and 5 W at 5 V.
Strong, Localized, and Directional Hydrogen Bonds Fluidize Ionic Liquids (2008)

Opposite effect of hydrogen bonding: Whereas molecular liquids are stabilized, ionic liquids can be fluidized by hydrogen bonds. Highly directional H bonds introduce “defects” into the Coulomb network resulting in reduced melting points and decreased viscosities. This is shown by the mid- and far-FTIR spectra of two ionic liquids. (Structure in black: all H bonds are possible, structure in white: methyl group prevents one H bond.)

A comparison of the absorption spectra of some typical symmetrical cyanine dyes (1936)

Abstract Compounds of the cyanine type show a wide variation in colour, whilst possessing comparatively simple chemical structures. They are, therefore, particularly suitable for a study of the relationship between colour and constitution. Such a study, for certain fairly simple series of cyanine dyes, free from substituents, forms the subject of the present paper. The cyanines are characterized by possessing two heterocyclic nuclei containing nitrogen. One of our objects was to find how the colour varies according to the nature of the nuclei, but we restricted the investigation to those series in which the two nuclei are identical.
Nanoimprint Lithography (2010)

Abstract CMOS image sensors represent a multi‐billion‐dollar market, with continued growth expected due to increasing demand for a multitude of consumer and industrial applications. To continue to drive down manufacturing costs while enabling increased device performance, manufacturers are looking to innovative production methods, such as nanoimprint lithography (NIL). In addition to lower cost, NIL offers high repeatability and accuracy, all of which are particularly critical for ensuring optimal production of micro lenses, which are an integral part of the CMOS image sensor. Beyond CMOS image sensors, NIL offers the potential to enable a number of other device applications, from high‐brightness light emitting diodes (HB‐LEDs) to micro‐fluidics.
Vitamin-C Delivery from CoCr Alloy Surfaces Using Polymer-Free and Polymer-Based Platforms For Cardiovascular Stent Applications (2014)

Antiproliferative drugs such as paclitaxel and sirolimus are delivered from stents to inhibit the growth of smooth muscle cells (SMCs) for preventing neointimal hyperplasia. However, these drugs delay the growth of endothelial cells (ECs) as well and cause late stent thrombosis. We recently demonstrated the use of Vitamin-C (l-ascorbic acid, l-AA) over paclitaxel and sirolimus for inhibiting SMCs growth and promoting EC growth simultaneously. In this study, we have investigated the delivery of l-AA from CoCr alloy surfaces for potential use in stents. A polymer-free phosphoric acid (PA) platform and a polymer-based poly(lactic-co-glycolic acid) (PLGA) platform were used for coating l-AA onto CoCr surfaces. For the PA platform, FTIR confirmed that the PA was coated on CoCr, while the AFM showed that the PA coating on the CoCr surface was homogeneous. The successful deposition of l-AA on PA-coated CoCr was also confirmed by FTIR. The uniform distribution of l-AA crystals on PA-coated CoCr was shown by SEM, optical profilometer, and AFM. The drug release studies showed that l-AA (276 μg/cm(2)) was burst released from the PA platform by 1 h. For the PLGA platform, SEM showed that the l-AA incorporated polymer films were smoothly and uniformly coated on CoCr. FTIR showed that l-AA was incorporated into the bulk of the PLGA film. DSC showed that the l-AA was present in an amorphous form and formed an intermolecular bonding interaction with PLGA. The drug release studies showed that l-AA was sustained released from the PLGA coated CoCr for up to 24 h. The SEM, FTIR, and DSC characterizations of samples collected post drug release shed light on the mechanism of l-AA release from PLGA coated CoCr. Thus, this study demonstrated the delivery of l-AA from biomaterial surfaces for potential applications in stents and other implantable medical devices.
Accurate Lung Segmentation For X-ray CT Images (2007)

Segmentation of pulmonary X-ray computed tomography image is the first step to detect nodule of lung. This paper presents a fully automatic method for segmenting lung from three-dimensional thorax. First, the large airway is removed from lung region by anisotropic diffusion to smooth edges and region- growth. Second, we use an optimal threshold to automatically choose a threshold value, get binary images, and remove vessel of pulmonary using the optimal threshold. Third, left and right lungs are separated by detecting the anterior and posterior junctions using the largest threshold. Finally, we smooth the lung boundary along the mediastinum and lung wall by morphological smoothing. We show that our results are better than that achieved manually. Since there are no accepted criteria for defining the lung boundary near the mediastinum, we believe that our method of defining the boundary of lung near the mediastinum based on the structure of the airway tree provides a good basis for three-dimensional smoothing.
Reconstruction of audio waveforms from spike trains of artificial cochlea models (2015)

Spiking cochlea models describe the analog processing and spike generation process within the biological cochlea. Reconstructing the audio input from the artificial cochlea spikes is therefore useful for understanding the fidelity of the information preserved in the spikes. The reconstruction process is challenging particularly for spikes from the mixed signal (analog/digital) integrated circuit (IC) cochleas because of multiple non-linearities in the model and the additional variance caused by random transistor mismatch. This work proposes an offline method for reconstructing the audio input from spike responses of both a particular spike-based hardware model called the AEREAR2 cochlea and an equivalent software cochlea model. This method was previously used to reconstruct the auditory stimulus based on the peri-stimulus histogram of spike responses recorded in the ferret auditory cortex. The reconstructed audio from the hardware cochlea is evaluated against an analogous software model using objective measures of speech quality and intelligibility; and further tested in a word recognition task. The reconstructed audio under low signal-to-noise (SNR) conditions (SNR < -5 dB) gives a better classification performance than the original SNR input in this word recognition task.

Über die Struktur und das Hochdruckverhalten des β-Li<sub>6</sub>UO<sub>6</sub>. (1976)

Li 6 UO 6 has a reversible phase transformation at 680°C and decomposes above about 850°C. At high pressure the low temperature modification becomes unstable because of an invariant point in the system Li 2 O—Li 4 UO 5 at approximately 13 Kb and 620°C. β-Li 6 UO 6 has a triclinic unit cell with a = 5.203, b= 5.520, c = 5.536 Å, α = 114.7, β = 120.7 and γ = 75.5°. The close relationship between the crystal structures of Li 6 TeO 6 and Li 6 UO 6 is also suggested from similar infrared spectra and from partial solid solution Li 6 UO 6 —Li 6 TeO 6 .

Deacetylation was carried out with NH 4 OH.
Complete structure determination ofN-acetyl-D-galactosamine-binding mistletoe lectin-3 fromViscum album L. album (2004)

The primary structure of the B chain of the N-acetyl-D-galactosamine-recognizing mistletoe lectin-3 (ML-3B) has been deduced from proteolytic digest peptides of the purified glycoprotein, their HPLC-separation and Edman degradation and confirmation of the peptide sequences by MALDI-MS. ML-3B consists of 262 amino acid residues including 10 cysteine moieties. The structure and linkage of the carbohydrate side chains, connected to two N-glycosylation sites at positions Asn(95) and Asn(135) of the lectin, were determined by a combination of glycosidase treatment and MALDI-MS of corresponding glycopeptide fragments. The sequence alignment reveals a high homology with other B chains of type-II RIPs, although there are remarkable differences in the D-galactose-specific mistletoe lectin-1B chain. The recently published primary structure of the mistletoe lectin-3A chain1 and the now available primary sequence of the 3B chain allowed the construction of a preliminary homology model of ML-3. The model demonstrates, unequivocally, that ML-3 is a member of the type-II RIP family with rigid conservation of the enzymatic active site of the A chain and an identical overall protein fold. Specific amino acid residue exchanges and the different glycosylation pattern in comparison with ML-1 are discussed and related to the properties of the two glycoproteins. The knowledge of the complete primary structure of mistletoe lectin-3 is a major contribution towards more insight into the mechanism of the biological activity of commercial mistletoe preparations.
Superposition mapping with application in bit-interleaved coded modulation (2010)

Superposition mapping (SM) is a modulation technique which converts bit tuples into symbols via linear superposition instead of bijective mapping. Since the resulting signal is often Gaussian-like, it has a good theoretical potential to approach the capacity of Gaussian channels. This paper discusses available SM schemes in a systematic manner, with particular focus on their performance when applied in the framework of bit-interleaved coded modulation (BICM).
A Robust Polynomial Fitting Approach for Contact Angle Measurements (2013)

Polynomial fitting to drop profile offers an alternative to well-established drop shape techniques for contact angle measurements from sessile drops without a need for liquid physical properties. Here, we evaluate the accuracy of contact angles resulting from fitting polynomials of various orders to drop profiles in a Cartesian coordinate system, over a wide range of contact angles. We develop a differentiator mask to automatically find a range of required number of pixels from a drop profile over which a stable contact angle is obtained. The polynomial order that results in the longest stable regime and returns the lowest standard error and the highest correlation coefficient is selected to determine drop contact angles. We find that, unlike previous reports, a single polynomial order cannot be used to accurately estimate a wide range of contact angles and that a larger order polynomial is needed for drops with larger contact angles. Our method returns contact angles with an accuracy of <0.4° for solid-liquid systems with θ < ~60°. This compares well with the axisymmetric drop shape analysis-profile (ADSA-P) methodology results. Above about 60°, we observe significant deviations from ADSA-P results, most likely because a polynomial cannot trace the profile of drops with close-to-vertical and vertical segments. To overcome this limitation, we implement a new polynomial fitting scheme by transforming drop profiles into polar coordinate system. This eliminates the well-known problem with high curvature drops and enables estimating contact angles in a wide range with a fourth-order polynomial. We show that this approach returns dynamic contact angles with less than 0.7° error as compared to ADSA-P, for the solid-liquid systems tested. This new approach is a powerful alternative to drop shape techniques for estimating contact angles of drops regardless of drop symmetry and without a need for liquid properties.
