Improvement of “Text Steganography Based on Unicode of Characters in Multilingual” by Custom Font with Special Properties (2020)

Abstract Since computer utilization is expanding, for both social and trade ranges, secure communications through channels got to be an exceptionally critical issue. Information hiding away could be a strategy to get a secure communication medium and securing the data amid transmission. Text documents have very less redundant information as compared to the images and audio, therefore, text steganography is most challenging. This paper aims to improve “text steganography based on Unicode of characters in multilingual” by design new font with special properties for purposes of hiding data. Furthermore, this method based on making the same glyphs for the multiple codes, the Set of High-Frequency Letters called SHFL in the English language was chosen for the embedding process. The hiding method replaces the code of English symbol with other code that has the same glyph exactly. Two bits are hidden at once, utilizing glyph1 for hiding 00 and utilizing glyph2, glyph3, and glyph4 for hiding 01, 10, and 11. The improvement increases the steganography capacity, transparency and improves the security and robustness of the text stego file.
Aqueous Synthesis of Glutathione‐Capped ZnSe and Zn<sub>1–</sub><sub><i>x</i></sub>Cd<sub><i>x</i></sub>Se Alloyed Quantum Dots (2007)

Glutathione-capped ZnSe and Zn1–xCdxSe alloyed quantum dots (QDs) have been successfully synthesized in aqueous solution (see figure). Their fluorescence emissions are tunable between 360 and 500 nm. The as-prepared QDs have a quantum yield of up to 50 %, comparable to or better than most QDs prepared by an organometallic route. The approach can be easily scaled up for commercial production of alloyed nanocrystals of various compositions.
Analysis of a method for obtaining near-diffraction-limited information in the presence of atmospheric turbulence (1973)

A new technique (speckle interferometry) has been developed by Gezari, Labeyrie, and Stachnik, which allows the measurement of stellar diameters from a series of photographs obtained from large-aperture ground-based telescopes. The series of photographs is processed to obtain the Weiner spectrum of the photographic image, i.e., the ensemble-averaged modulus-squared Fourier transform obtained from the series of images. Gezari, Labeyrie, and Stachnik have measured stellar diameters as small as 0″.05, about 20 times better than is usually possible. In this paper, mathematical expressions are obtained for the Wiener spectrum of the image of a point source. As is well known, the Wiener spectrum of the image of an extended, incoherently radiating object, is expressible as a product of this point-source spectrum and the object spectrum. Calculations are performed using the Rytov approximation and assuming that the underlying atmospheric turbulence is describable by a Kolmogorov spectrum. Asymptotic closed-form expressions are obtained for angular frequencies much less than, and much greater than, the conventional seeing limit. In the latter case, the Wiener spectrum is found to be proportional to the optical transfer function.
Ultrasmall Sn Nanoparticles Embedded in Carbon as High‐Performance Anode for Sodium‐Ion Batteries (2014)

Designed as a high‐capacity, high‐rate, and long‐cycle life anode for sodium‐ion batteries, ultrasmall Sn nanoparticles (≈8 nm) homogeneously embedded in spherical carbon network (denoted as 8‐Sn@C) is prepared using an aerosol spray pyrolysis method. Instrumental analyses show that 8‐Sn@C nanocomposite with 46 wt% Sn and a BET surface area of 150.43 m 2 g −1 delivers an initial reversible capacity of ≈493.6 mA h g −1 at the current density of 200 mA g −1 , a high‐rate capacity of 349 mA h g −1 even at 4000 mA g −1 , and a stable capacity of ≈415 mA h g −1 after 500 cycles at 1000 mA g −1 . The remarkable electrochemical performance of 8‐Sn@C is owing to the synergetic effects between the well‐dispersed ultrasmall Sn nanoparticles and the conductive carbon network. This unique structure of very‐fine Sn nanoparticles embedded in the porous carbon network can effectively suppress the volume fluctuation and particle aggregation of tin during prolonged sodiation/desodiation process, thus solving the major problems of pulverization, loss of electrical contact and low utilization rate facing Sn anode.

In-situ Doping and Local Overcompensation of High Performance LPCVD Polysilicon Passivated Contacts as Approach to Industrial IBC Cells (2016)

In this work, we investigate polysilicon passivation contacts, to be used for high performance IBC cells. We demonstrate an LPCVD process for in-situ p-type doped polysilicon. The p-type polysilicon can be locally overcompensated to n-type polysilicon using phosphorous implantation or POCl3 diffusion. Both contacts show excellent surface passivation, with recombination current (Jo) of 12 fA/cm2 for p-poly on a polished Si surface, and less than 10 fA/cm2 for compensated n-poly both on textured and polished surfaces. These polysilicon layers are implemented in the fabrication of n-PERT cells with front and rear polysilicon contacts. The resulting textured half-fabricated cells have an implied Voc of 701 mV after hydrogenation via PECVD deposition of SiNx:H. Different metallization processes, relevant for IBC cells, are applied. A Voc of 685 mV is obtained for the best cell metallized with low-temperature metallization (ITO/low-temperature Ag paste), and 678 mV is obtained for the best cell with industrial screen-printed firing-through contacts. In these n-PERT cells the same thin oxide layer is used for p-type and n-type polysilicon contacts.
A mapping of investor’s risk profile (2013)

In this paper we analyze a questionnaire, aimed to evaluate the investors’ risk profile. The questionnaire focuses on the following fundamental aspects: investor’s knowledge and financial experience; financial objectives; personal predisposition to risk/earn; temporal horizon. The analysis consists in a visualization of the dataset, provided by the new VOS method, and it is based on similarity measures between the individuals’ response patterns. The result is a pure descriptive statistical analysis which does not involve any model assumption.
Greening the video transcoding service with low-cost hardware transcoders (2016)

Video transcoding plays a critical role in a video streaming service. Content owners and publishers need video transcoders to adapt their videos to different formats, bitrates, and qualities before streaming them to end users with the best quality of service. In this paper, we report our experience to develop and deploy VideoCoreCluster, a low-cost, highly efficient video transcoder cluster for live video streaming services. We implemented the video transcoder cluster with low-cost single board computers, specifically the Raspberry Pi Model B. The quality of the transcoded video delivered by our cluster is comparable with the best open source software-based video transcoder, and our video transcoders consume much less energy. We designed a scheduling algorithm based on priority and capacity so that the cluster manager can leverage the characteristics of adaptive bitrate video streaming technologies to provide a reliable and scalable service for the video streaming infrastructure. We have replaced the software-based transcoders for some TV channels in a live TV streaming service deployment on our university campus with this cluster.
Web Application User Interface Technologies (2011)

The World Wide Web has expanded from a huge information storage repository into a worldwide application platform. Web applications have several benefits compared to desktop applications. An application can be used anywhere from any system and device, which means that only one version is needed, they do not need to be installed and developers can modify running applications. Despite all the benefits of the Web, web applications are suffering because they are developed using the same technologies as the static documents on the Web. Some of these web technologies are outdated and were not originally designed for the complex use cases of the modern applications to which they are now applied. For instance, HTML forms comprise the main interaction of an application, despite not having been designed to describe complex and interactive UIs. Another example is HTTP communication on the Web, which always requires client initiative and is too restrictive for dynamic web applications. Additionally, new usage contexts have brought with them new requirements for web applications, which are no longer used only via Graphical User Interfaces. \n Recently, several parties have developed specialized technologies for web application development. These solutions are not only minor additions to the existing technologies, but also new technologies. The goal of this thesis is to analyze the advanced web technologies and propose improvements to the technologies and architecture where applicable. The technologies are evaluated against a large set of requirements. The aim of the evaluation is two-fold. The first part is to select a technology on which to base the further improvements, and the second is to identify the deficiencies of the current solutions. The improvements focus on the developers' point-of-view. \n Based on the evaluation, this thesis proposes certain improvements related to multimodal interaction, server push, and remote UI updates. It also discusses software that supports the improvements and XML-based web technologies. Finally, the improvements are evaluated against the requirements and compared to other solutions.

Coherent phonon excitation as nonequilibrium dopant activation process for ultra-shallow junction formation (2002)

A novel non-thermal dopant activation process is proposed based on coherent excitation of phonons in the frequency range of 10-100 GHz and 1-10 THz. Major objective of the proposed method is to achieve non-thermal annealing of the implanted dopants by directly and coherently inducing lattice vibration (i.e. phonons) to attain large amplitude for effective low-temperature activation of the dopants.
A Truncated Isoform of the Human β Chain Common to the Receptors for Granulocyte-Macrophage Colony-Stimulating Factor, Interleukin-3 (IL-3), and IL-5 With Increased mRNA Expression in Some Patients With Acute Leukemia (1998)

We report here a naturally occurring isoform of the human β chain common to the receptors for granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-3 (IL-3), and IL-5 (GMRβC) with a truncated intracytoplasmic tail caused by deletion of a 104-bp exon in the membrane-proximal region of the chain. This β intracytoplasmic truncated chain (βIT) has a predicted tail of 46 amino acids, instead of 432 for βC, with 23 amino acids in common with βC and then a new sequence of 23 amino acids. In primary myeloid cells, βIT comprised approximately 20% of the total β chain message, but was increased up to 90% of total in blast cells from a significant proportion of patients with acute leukemia. Specific anti-βITantibodies demonstrated its presence in primary myeloid cells and cell lines. Coexpression of βIT converted low-affinity GMRα chains (KD 2.5 nmol/L) to higher-affinity αβ complexes (KD 200 pmol/L). These could bind JAK2 that was tyrosine-phosphorylated by stimulation with GM-CSF. βITdid not support GM-CSF–induced proliferation when cotransfected with GMRα into CTLL-2 cells. Therefore, it may interfere with the signal-transducing properties of the βC chain and play a role in the pathogenesis of leukemia.

Isolation and characterization of adriamycin-resistant HL-60 cells which are not defective in the initial intracellular accumulation of drug. (1986)

Two human leukemia cell lines (Molt-4 and HL-60) have been used for establishing cells which exhibit a low level resistance to Adriamycin. Analysis of drug uptake patterns shows that the Molt-4 resistant cells are defective in the initial intracellular accumulation of drug. In contrast to Molt-4 the levels of drug which accumulate in the sensitive and resistant HL-60 cells during a 60-min incubation period are essentially the same. However, when incubations are continued there is a major reduction in intracellular drug levels in the resistant cell. Further studies show that resistant cells incubated in the presence of drug for extended time periods efflux drug at a rate considerably greater than that exhibited by the sensitive parent line. Similar efflux patterns are obtained with nuclei isolated from drug-sensitive and -resistant cells. Additional studies using an in vitro phosphorylation system demonstrate distinct protein changes in membranes of Molt-4 and HL-60 resistant cells. Thus, we have found that a membrane fraction from the Molt-4 resistant line contains a Mr 170,000 protein which is not detected in a similar fraction from cells sensitive to drug. HL-60 resistant membranes contain two proteins with molecular weights of 150,000 and 120,000 which are also not found in membranes from drug-sensitive cells. The results of this study suggest that drug resistance in HL-60 cells is related to an efflux mechanism which is triggered only after cells are exposed to drug for prolonged periods.
A REVIEW ON VARIOUS ANALYTICAL METHODS USED IN DETERMINATION OF DISSOCIATION CONSTANT (2014)

Determination of dissociation constant for a drug capable of ionization within a pH range of 1 to 10 is important since solubility and consequently absorption, can be altered by orders of magnitude with changing pH. The dissociation constant [pKa] value, are essential for understanding many fundamental reactions in chemistry. These values reveal the deprotonation state of a molecule in a particular solvent. There is great interest in using experimental methods to calculate the pKa values for many different types of molecules. In this review the most valuable methods for determining accurate pKa values are presented. There are many diverse strategies for determining dissociation constant, so the main aim of the review is to discuss the available analytical methods.

Catalytic Asymmetric Oxidative Couplings of 2-Naphthols by Tridentate <i>N</i>-Ketopinidene-Based Vanadyl Dicarboxylates (2002)

[reaction: see text] A series of oxovanadium(IV) complexes derived from tridentate N-ketopinidene-alpha-amino acids were synthesized. They serve as efficient catalysts for the enantioselective oxidative couplings of various 3-, 6-, or 7-substituted 2-naphthols. The best scenario involves the use of a vanadyl complex arising from L-tert-leucine in CCl4. The asymmetric couplings of 2-naphthols can be conducted smoothly at 40-45 degrees C under a stream of gaseous oxygen, leading to 2,2'-dihydroxy-1,1'-binaphthyls in good yields (61-99%) and with enantioselectivities of up to 87%.
Multi-scale Non-Local Kernel Regression for super resolution (2011)

In this paper, we propose an extension of the Non-Local Kernel Regression (NL-KR) method and apply it to super-resolution (SR) tasks. The proposed method extends NL-KR via generalizing the self-similarity from single-scale to multi-scale, and propose an effective SR algorithm using the proposed multi-scale NL-KR model. Experimental results on both synthetic and real images demonstrate the effectiveness of the proposed method.
Preclinical Behavioral Approaches to the Identification and Study of Antipsychotic Drug Action and Schizophrenia (2003)

Schizophrenia is a group of illnesses of unknown origin with a yearly prevalence of 0.4–0.8% in the general population (Dohrenwend, 1980). Schizophrenia is characterized by a spectrum of symptoms that are commonly grouped into positive (including hallucinations, incoherence, delusions, distorted thought, and incongruity of affect) and negative (including poverty of speech, flat affect, low social drive, curbing of interest, and diminished sense of purpose) categories (Crow, 1980; Berrios, 1985; Kane, 1993a).
Ringer's ethyl pyruvate in hemorrhagic shock and resuscitation does not improve early hemodynamics or tissue energetics. (2005)

Reactive oxygen species (ROS) have been implicated in the pathogenesis of hemorrhagic shock. Ethyl pyruvate, a derivative of pyruvate and a proposed oxygen radical scavenger, is attractive as a possible resuscitation fluid. We investigated whether resuscitation with lactated Ringer's (LR) containing ethyl pyruvate (REP) had any hemodynamic or tissue energetic benefits compared with LR alone for hemorrhagic shock. Hemorrhagic shock was induced in splenectomized pigs via inferior vena cava cannula. After 90 min of shock, animals were resuscitated in a stepwise fashion with LR or REP (30 mg/kg/dose, given as 1.5 mg/mL in LR) at 20 cc/kg/step for four steps. Data collected during this experiment included physiologic and hemodynamic parameters, near-infrared reflectance spectroscopy measurements of tissue hemoglobin oxygen (StO(2)) of the stomach, liver, and hind limb, and nuclear magnetic resonance phosphorus spectra of the liver and hind limb at each time point. In both resuscitative groups, heart rate, and lactate and pyruvate values increased during shock and began to drop toward baseline values during resuscitation. Mean arterial pressure, oxygen delivery, and oxygen consumption decreased during shock and increased toward baseline levels during the resuscitative process. There were no significant changes in physiologic parameters between the LR- and REP-resuscitated animals. There was a significantly lower stomach StO(2) and hind limb cellular cytoplasmic pH during later resuscitative endpoints in REP-resuscitated animals. The clinical significance of these findings are unclear. There is no short-term hemodynamic or tissue energetic advantage to using REP as a resuscitation fluid when compared with LR. Long-term outcome studies are needed to further evaluate any potential benefits of use of REP in hemorrhagic shock.
