Pyrrolic tripodal receptors for carbohydrates. Role of functional groups and binding geometry on carbohydrate recognition (2010)

The contribution from several H-bonding groups and the impact of geometric requirements on the binding ability of benzene-based tripodal receptors toward carbohydrates have been investigated by measuring the affinity of a set of structures toward octyl β-D-glucopyranoside, selected as a representative monosaccharide. The results reported in the present study demonstrate that a judicious choice of correct geometry and appropriate functional groups is critical to achieve the complementary hydrogen bonding interactions required for an effective carbohydrate recognition.
Design of a switch for network on chip applications (2003)

System on Chip (SoC) design in the forthcoming billion transistor era will involve the integration of numerous heterogeneous semiconductor intellectual property (IP) blocks. Some of the main problems in the ultra deep sub micron technologies characterized by gate lengths in the range of 50-100 nm arise from non-scalable global wire delays, failure to achieve global synchronization, errors due to signal integrity issues, and difficulties associated with non-scalable bus-based functional interconnect. These problems are addressed in this paper by introducing a new design methodology. A switch-based network-centric architecture to interconnect IP blocks is proposed. We introduce a butterfly fat tree architecture as an overall interconnect template. In this new interconnect architecture, switches are used to transfer data between IP blocks. To reduce overall latency and hardware overhead, wormhole routing is adopted. The proposed switch architecture supports this routing method. Initial implementation of the switch reveals that the total switch area is expected to amount to less than 2% of a large SoC.
Model‐Based Software Testing (2002)

Abstract There is an abundance of testing styles in the discipline of software engineering today. Over the last few decades, many of these have come to be used and adopted by the industry as solutions to address the increasing demand for assuring software quality. Since 1990 or so, perhaps as an outcome of the popularization of object orientation and models in software engineering, there has been a growth in black‐box testing techniques that are collectively dubbed model‐based testing . Model‐based testing (MBT) is a general term that signifies an approach that bases common testing tasks such as test case generation and test result evaluation [see Jorgensen (1995) for some of these basic terms and concepts] on a model of the application under test. This generic definition is probably the least general statement that can be made about MBT. One of the striking issues about MBT is the nonstandard lingo that reflects a diversity of philosophies and models. Another issue that one will eventually realize in studying this set of techniques is that the models and techniques have yet to travel the long course to maturity. Disregarding these concerns, model‐based techniques have gained the attention of practitioners and theoreticians alike. The wealth of published work portraying case studies in both academic and industrial settings is a sign of the newfound interest in this youthful branch of testing. Model‐based techniques have substantial appeal. The first sign of potential are studies showing that testing a variety of applications has been met with success when MBT was employed. This article discussed what a model is and gives some models that have been useful for testing. Information given or choosing a module, building it, and testing it, The present and future status of model‐based software testing is detailed.
Conductive rubber electrodes for earphone-based eye gesture input interface (2013)

An eartip made of conductive rubber that also realizes bio-potential electrodes is proposed for a daily-use earphone-based eye gesture input interface. Several prototypes, each with three electrodes to capture Electrooculogram (EOG), are implemented on earphones and examined. Experiments with one subject over a 10 day period reveal that all prototypes capture EOG similarly but they differ as regards stability of the baseline and the presence of motion artifacts. Another experiment conducted on a simple eye-controlled application with six subjects shows that the proposed prototype minimizes motion artifacts and offers good performance. We conclude that conductive rubber with mixed Ag filler is the most suitable setup for daily-use.
The design and testing of a DSP, half-duplex, vertical, DPSK communication link (2002)

Accurate in-situ studies of the oceans requires an efficient, fast and reliable method of transmitting information to and from dedicated scientific payloads. The current generation of underwater telemetry systems tend to use proven, low data rate, 'discrete-component' designs. Although these systems perform well in static environments, their performance rapidly degenerates when the environment becomes more dynamic. The next generation of underwater telemetry systems must be able to adapt automatically to the changing environment and counteract time-varying effects by means of flexible signal processing techniques and detection algorithms. This goal is hard, if not impossible, to realise using conventional 'discrete component' designs. This paper presents a vertical communication system that uses an 'Analogue Devices' digital signal processor (DSP) at its heart. This DSP controls the transmission of data and operative commands to and from a seafloor unit, using multi-phase, 2, 4 or 8, differential phase shift keying (DPSK). This system is considered to be the first step towards a completely autonomous, adaptive communications system.
Congestion control and prevention in ATM networks (1991)

Some of the congestion control methods commonly considered suitable for an ATM (asynchronous transfer mode) network are surveyed. Call-level control, which provides preventive control by regulating the admission of new calls into the network, is first discussed. The concept of equivalent bandwidth is defined, and the sharing of network information is discussed. Admission control schemes are described. Methods for cell-level control, which avoids short term congestion, are considered. Included are call admittance, bandwidth policing, and rate control, as well as priority schemes that provide multiple grades of service with ATM.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The design of a low cost motion chair for video games and MPEG video playback (1996)

We have developed a low-cost force output device as a user interface and combine it with an MPEG-1 video player to form a virtual reality system for entertainment. We designed a motor-powered motion chair to create the sensation of being carried in an airplane or a vehicle. To obtain smooth motion, curve fitting and filtering on the motion trajectory are used. The synchronization of video and motion chair is solved with the techniques of motion prediction, while combined with a joystick provides a way for interactive games.
A collaborative personalized affective video retrieval system (2009)

In this demonstration, a collaborative personalized affective video retrieval is introduced. A dataset of 155 video clips extracted from Hollywood movies were annotated by the emotion felt by participants. More than 1300 annotations from 40 participants were gathered in a database to be used for affective retrieval system. The retrieval system is able to retrieve videos based on emotional keyword query as well as arousal and valence query. The user's personal profile (gender, age, cultural background) was employed to improve the collaborative filtering in retrieval.

Surface roughness estimation from GPS sea reflections (2003)

The research reported in this paper was motivated by a Global Positioning System (GPS) data set collected by researchers at The Johns Hopkins University, Applied Physics Laboratory (JHU/APL) in May 1999. Raw GPS signal data were collected from an aircraft equipped with two downlooking antennas for receiving both left-hand circularly polarized (LHCP) and right-hand circularly-polarized (RHCP) GPS reflections from the ocean surface. Concurrent measurements of the local wind and wave conditions were collected from a nearby research vessel. The measured (LHCP) waveforms were similar to those already reported. The reflected RHCP waveforms were about 10 dB below those from the LHCP antenna. As far as we know, detection of the (depolarized) RHCP waveform has not been previously demonstrated. Models for GPS surface scattering based on geometrical optics or the Kirchhoff approximation predict a very weak depolarized return. We have recently developed a general bistatic scattering model that yields the proper cross section for both the specular and resonant (Bragg) scattering limits and also predicts depolarization for scattering out of the plane of incidence. Comparison of this scattering model with the cross section obtained by exact integration of Maxwell's equations shows good agreement even for relatively rough surfaces.
Failure of Transdifferentiation of Adult Hematopoietic Stem Cells into Neurons (2006)

Previous studies of bone marrow-derived stem cell transdifferentiation into neurons have not involved purified cell populations and determined their exact phenotype prior to differentiation. The present study investigates whether highly purified mouse adult hematopoietic stem cells (HSCs), characterized by lineage marker depletion and expression of the cell surface markers Sca1 and c-Kit (Lin(-) Sca1(+) c-Kit(+) [LSK]), can be stimulated to adopt a neuronal fate. When the HSC(LSK) cells were cultured in vitro in neuronal differentiation medium supplemented with retinoic acid, 50% of the cells expressed the neural progenitor marker nestin and no cells had become postmitotic. Electrophysiological recordings on neuron-like cells showed that these cells were incapable of generating action potentials. When the HSC(LSK) cells either were grown in vitro together with neural precursor cells or were transplanted into the striatum or cerebellum of wild-type mouse, they either differentiated into Iba1-immunopositive macrophage/microglia or died. In conclusion, we demonstrate that adult HSC(LSK) cells do not have the capacity to leave the hematopoietic lineage and differentiate into neurons.

The Effect of Biodegradable Drug Release Coatings on the Electrical Characteristics of Neural Electrodes (2007)

This study describes how drug eluting coatings affect the signal quality of implantable microelectrodes. Polyimide-Platinum neural probes were micro fabricated and coated with a biodegradable polymer loaded with drug eluting nanoparticles. Electrical impedance spectroscopy was used to study how the coating affects electrical recording and stimulation characteristics. The measurements were performed in vitro and it was found that the biodegradable film slightly modified the measured impedance phase by +3deg at 10 kHz but not the magnitude. This change in impedance is permanent but does not adversely affect the recording and stimulation characteristics of the device. This result demonstrates the compatibility of controlled release drug coatings with neural probes.
Evaluation of the relationship between emotional concepts and emotional parameters on speech (2002)

We propose a linear model of the relationship between the physical changes in speech and perceived emotional concepts. We make use of orthogonal bases in spite of the emotional words and the physical parameters themselves in order to avoid dependence on the method of selecting words and parameters. Furthermore we regard the emotions that listeners perceive from speech as the standard or emotional concepts because the emotions that speakers intended rely on their personality and temporary psychological state. Evaluation for relative information indicates that the proposed linear model is representable for the relationship between the physical quantities and psychological quantities in speech.
An efficient method of elliptic curve encryption using Ancient Indian Vedic Mathematics (2005)

The major time consuming arithmetic operations in ECC are point additions and doubling. Exponentiation operations like square and cube are the major bottlenecks in the efficiency of point additions and doubling. This paper presents efficient hardware circuitry for point doubling using square algorithms of Ancient Indian Vedic Mathematics. In order to calculate the square of a number, "Duplex" D property of binary numbers is proposed.

Charge transport in organic crystals: Theory and modelling (2010)

Abstract Efficient charge transport in organic semiconductors is the key for their application in Organic Electronics. Therefore the most important design ansatz is directed to improve carrier mobilities by means of available tools such as chemical and/or structural modifications of the organic materials. Thereby theoretical input can provide guidelines towards possible realizations of high‐mobility or, more general, highly functional materials. In particular the structure–property relationship is at the heart of theoretical studies which are extremely helpful if they achieve predictive power. In this paper we systematically review several charge‐transport approaches and illustrate their relationship in order to display their capabilities regarding this goal. Special focus is put on the transport mechanism, the mobility anisotropy and temperature dependence of charge‐carrier transport. As the central concept the inclusion of the strong coupling of the carriers with the vibrating lattice and, hence, the dressing of carriers to polarons is described. The availability of material parameters is tremendously important for transport description. We highlight their computation by ab initio theory in order to arrive at a satisfactory level beyond phenomenological approaches.
Microprocessor realization of a linear predictive vocoder. (2005)

A microprocessor realization for a linear predictive vocoder is presented. The goal was a low power, low cost, compact special purpose realization of a narrowband speech terminal. The resultant design is a general purpose two bus structure running at a 150 ns cycle time using as the basic signal processing element four of the AMD 2901 CPE chips. This basic structure is augmented by a four cycle multiplier to allow for sufficient signal processing power. The design concessions that mark the LPCM as a special purpose machine designed to be a speech terminal are: limited I/O, and limited memory. The present design requires 162 dual-in-line packages, dissipates less than 45 watts and occupies about 1/3 cubic foot.
Inexpensive Magnetic Field Controller (2006)

The problem is addressed and a brief description of both hardware and software of the controller are given. Results for magnetic field stability are presented, including an evaluation of the precision of the magnetic field probe.
Dror, a potential neurotrophic receptor gene, encodes a Drosophila homolog of the vertebrate Ror family of Trk-related receptor tyrosine kinases. (1993)

We have identified a Drosophila gene, Dror, which encodes a putative receptor tyrosine kinase (RTK) and maps to cytological location 31B/C on the second chromosome. In embryos, this gene is expressed specifically in the developing nervous system. The Dror protein appears to be a homolog of two human RTKs, Ror1 and Ror2. Dror and Ror1 proteins share 36% amino acid identity in their extracellular domains and 61% identity in their catalytic tyrosine kinase (TK) domains. Ror1 and Ror2 were originally identified on the basis of the similarity of their TK domains to the TK domains of members of the Trk family of neurotrophin receptors. The Dror protein shows even greater similarity to the Trk proteins within this region than do the human Ror proteins. In light of its similarity to trk and its neural-specific expression pattern, we suggest that Dror may encode a neurotrophic receptor that functions during early stages of neural development in Drosophila.
Disappearance of plasmalogens from membranes of animal cells subjected to photosensitized oxidation. (1988)

Chinese hamster ovary cells (CHO-K1) photosensitized with 12-(1'-pyrene)dodecanoic acid (P12) are killed when exposed to long wavelength ultraviolet (UV) light (greater than 300 nm). Mutants deficient in plasmalogen biosynthesis are hypersensitive to this treatment. We now demonstrate that plasmenylethanolamine is rapidly and preferentially destroyed when CHO-K1 cells, photosensitized either with P12 or merocyanine 540, are irradiated with light of the appropriate wavelength. Using [2-14C]ethanolamine, [1-14C]hexadecanol, or [U-14C]hexadecanol to follow the turnover of plasmenylethanolamine, we show that 2-monoacylglycerophosphoethanolamine, formic acid, and pentadecanal are formed during P12/UV treatment of CHO-K1 cells, but not of mutant cells deficient in plasmalogen synthesis. The decomposition of plasmenylethanolamine is O2-dependent, is enhanced in D2O, and is reduced in the presence of sodium azide. The process may be explained, in part, by the cycloaddition of singlet oxygen to the vinyl ether linkage of plasmenylethanolamine, generating a dioxetane intermediate that would be expected to decompose under physiological conditions to the observed products. An additional possibility is the formation of an allylic hydroperoxide at the 1'-carbon of the alkyl moiety by an "ene" reaction of singlet oxygen, or by radical-mediated oxidation, followed by metabolism or chemical decomposition of the hydroperoxide. Given the P12/UV hypersensitivity of plasmalogen-deficient mutants, we suggest that plasmalogens might protect animal cell membranes from singlet oxygen and/or radical-initiated oxidation by functioning as scavengers and decomposing to products that can be reutilized.
The Bacillus BioBrick Box 2.0: expanding the genetic toolbox for the standardized work with Bacillus subtilis (2017)

Standardized and well-characterized genetic building blocks allow the convenient assembly of novel genetic modules and devices, ensuring reusability of parts and reproducibility of experiments. In the first Bacillus subtilis-specific toolbox using the BioBrick standard, we presented integrative vectors, promoters, reporter genes and epitope tags for this Gram-positive model bacterium. With the Bacillus BioBrick Box 2.0, we significantly expand the range of our toolbox by providing new integrative vectors, introducing novel tools for fine-tuning protein expression, and carefully evaluating codon-adapted fluorescence proteins in B. subtilis, which cover the whole spectrum of visible light. Moreover, we developed new reporter systems to allow evaluating the strength of promoters and ribosome binding sites. This well-evaluated extension of our BioBrick-based toolbox increases the accessibility of B. subtilis and will therefore promote the use of this model bacterium and biotechnological workhorse as a host for fundamental and applied Synthetic Biology projects.
Detection and genotyping of CMV and HPV in tumors and fallopian tubes from epithelial ovarian cancer patients (2019)

Viral and bacterial infections are detected in epithelial ovarian cancer (EOC) tissues. Since the fallopian tubes are often affected by pelvic inflammatory disease (PID) and the majority of serous EOCs appear to originate from dysplastic lesions in the distal tube, it is relevant to consider the potential role that infectious agents may play in ovarian carcinogenesis. We sought to analyze the prevalence of human papillomavirus (HPV) and cytomegalovirus (CMV) in EOC tissue and fallopian tube specimens obtained at tumor resection. Ovarian cancer and fallopian tube tissue samples obtained from patients with EOC were analyzed by both qualitative and quantitative PCR to detect and quantify viral DNA. The presence of CMV and HPV DNA was detected in 70% and 74% cancerous ovarian tissues, respectively, and was significantly higher in EOC than in benign tumor cases (P ≤ 0.01). CMV or HPV infection was observed also in the fallopian tube samples. Infection with HPV16 was determined in 70% of EOC cases. Almost two thirds of EOC patients demonstrated coinfection with CMV and HPV in the pathological samples. The results revealed that the presence of CMV and HPV in EOC samples is common. CMV and HPV infections can be potential risks for EOC development.
