Effect of relaying on coverage in realistic deployment scenarios (2012)

In this paper, we investigate the impact of fixed relay deployment on coverage in a wireless infrastructure. We consider a realistic scenario with OFDM based transmission which takes into account some practical constraints and assumptions (path-loss models, power, etc...). We analyze and compare scenarios with relays which operate in both half-duplex and full-duplex modes. Relays are assumed to perform decode-and-forward strategy. We show that for half-duplex scenarios, multiple relays can be deployed to extend the coverage and to compensate the loss of the half-duplex constraint where SFN-like transmission is used at the relays, i.e, the relays share the same subcarriers. Full-duplex mode outperforms the half-duplex mode in terms of coverage on the expense of additional complexity at the receiver side and offers a more convenient solution when the relay transmission power is constrained. The main contribution of this paper is giving guidelines for relay deployment in practical environments, and providing insight into benefits relays can offer in terms of coverage extension in realistic deployment scenarios.

GaP Green Light-Emitting Diodes with<i>p</i>-<i>n</i>-<i>p</i>-<i>n</i>Structure (1972)

Green light-emitting gallium phosphide diodes with p-n-p-n structure were obtained by means of double liquid-phase epitaxy onto a pulled GaP substrate in a graphite boat. The first n-region is the substrate crystal, the first p-region and the second n-region are formed in the first epitaxial layer, and the second p-region is the second epitaxial layer. Photoluminescence measurements showed that the p-region in the first epitaxial layer is formed by cross compensation of donor impurity with a carbon acceptor from the graphite boat. Negative resistance is observed in these diodes with a switching voltage of about 3 to 160 volts and with a holding voltage of about 2 volts. Switching time is inversely proportional to the difference between the applied voltage and switching voltage, and depends on the duty cycle of the applied voltage, particularly at low temperatures. Quantum efficiency of green emission after switch-on is about 1.5×10-4 at a current density of 10 Acm-2.
Complete separation of magnetic nanoparticlesvia chemical cleavage of dextran by ethylenediamine for intracellular uptake (2009)

Completely water dispersible and highly monodispersed superparamagnetic iron oxide nanoparticles (SPIONs) were prepared. The surface of SPIONs was modified with dual-crosslinked amine activated dextran (AMD) and chemical cleavage of AMD on SPIONs was carried out by ethylenediamine hydrochloride (EDA). Transmission electron microscopy (TEM) revealed that individual SPIONs were completely separated in water and the average diameter of resulting nanoparticles was 4.4 nm.
pH‐Sensitive Release of Ketoprofen from Sodium Laurate‐loaded Poly(acryloyl‐L‐proline methyl ester) Gels (1997)

Sodium laurate was incorporated into polymer gels with a thermo-triggered function based on acryloyl-L-proline methyl ester, to give a further pH-triggered drug-delivery function.



In the absence of sodium laurate, the gel remained unswelled in solutions ranging in pH from 3.0 to 9.0 at 37°C. However, a significant swelling occurred by introduction of sodium laurate at pH values greater than 5.0, followed by a reversal of the swelling after release of sodium laurate from within the gel.



We conclude that the release of ketoprofen from sodium laurate-loaded poly(acryloyl-L-proline methyl ester) gels could be demonstrated in-vitro, suggesting that the loaded gels are promising as a pH- and thermo-specific drug carrier.

Radiation characterization of an intra-oral wireless device at multiple ISM bands: 433 MHZ, 915 MHZ, and 2.42 GHz (2010)

Intra-oral wireless devices are becoming more popular for physiological monitoring of the mouth environment and tongue-operated assistive technologies, such as the internal Tongue Drive System (iTDS). Here we present the experimental measurements and simulations of radiation performance of three commercial wireless transmitters operating at 433 MHz, 915 MHz, and 2.42 GHz, in the industrial-scientific-medical band when they were placed inside human mouth. The measurement and simulation results showed similarities in the attenuation patterns of all tested devices and indicated that the maximum attenuation occurs on the back of the head. There were no significant difference of average attenuation pattern between 433 MHz and 915 MHz, while the attenuation of 2.42 GHz was higher in simulations but not in the measurements.
Super‐refraction effects on GPS radio occultation refractivity in marine boundary layers (2010)

With the combination of global coverage, high vertical resolution, and all‐weather capability, GPS radio occultation (RO) is an emerging satellite remote sensing technique that can probe the atmospheric boundary layer (ABL) on a global basis. However, a systematic negative bias (commonly referred to as N ‐bias) remains in derived refractivity profiles in the ABL. In this paper we present the N ‐biases in COSMIC RO soundings with respect to ECMWF analyses, which show a seasonally varying pattern clustered over the oceans where super‐refraction (SR) often occurs. A case study of coincident COSMIC RO and radiosonde sounding confirms that the N ‐bias is primarily caused by SR. We also show that the high‐rate RO bending angle measurements can resolve the ABL top at a vertical resolution better than 100 m. A reconstruction method is applied to one case where SR occurs and significantly reduces the negative refractivity error in the ABL.
Design and Packaging of Fault Tolerant Optoelectronic Multiprocessor Computing Systems (1991)

Abstract : There is considerable interest in developing optical interconnects for multi-chip modules (MCM). As a consequence, there is the basic need in developing a methodology for partitioning the system for effective utilization of the optical and electronic technologies. For the given netlist of a system design, key question to be answered is where to use optical interconnections. This paper introduces the Computer Aided Design (CAD) approach for partitioning opto-electronic systems into Opto-Electronic Multichip Modules (OE MCM). We will first discuss the design tradeoff issues in optoelectronic system design including speed, power dissipation, area and diffraction limits for free space optics. We will then define a formulation for OE MCM partitioning and describe new algorithms for optimizing this partitioning based on the minimization of the power dissipation. The models for the algorithms are discussed in detail and an example of a multistage interconnect network is given. Different results, with the number and size of chips being variable, are presented where improvement for the system packaging has been observed when the partitioning algorithm are applied.
Sequence-dependent sliding kinetics of p53 (2012)

Proper timing of gene expression requires that transcription factors (TFs) efficiently locate and bind their target sites within a genome. Theoretical studies have long proposed that one-dimensional sliding along DNA while simultaneously reading its sequence can accelerate TF's location of target sites. Sliding by prokaryotic and eukaryotic TFs were subsequently observed. More recent theoretical investigations have argued that simultaneous reading and sliding is not possible for TFs without their possessing at least two DNA-binding modes. The tumor suppressor p53 has been shown to slide on DNA, and recent experiments have offered structural and single molecule support for a two-mode model for the protein. If the model is applicable to p53, then the requirement that TFs be able to read while sliding implies that noncognate sites will affect p53's mobility on DNA, which will thus be generally sequence-dependent. Here, we confirm this prediction with single-molecule microscopy measurements of p53's local diffusivity on noncognate DNA. We show how a two-mode model accurately predicts the variation in local diffusivity, while a single-mode model does not. We further determine that the best model of sequence-specific binding energy includes terms for "hemi-specific" binding, with one dimer of tetrameric p53 binding specifically to a half-site and the other binding nonspecifically to noncognate DNA. Our work provides evidence that the recognition by p53 of its targets and the timing thereof can depend on its noncognate binding properties and its ability to change between multiple modes of binding, in addition to the much better-studied effects of cognate-site binding.

Resistance to different classes of drugs is associated with impaired apoptosis in childhood acute lymphoblastic leukemia (2003)

Resistance of leukemic cells to chemotherapeutic agents is associated with an unfavorable outcome in pediatric acute lymphoblastic leukemia (ALL). To investigate the underlying mechanisms of cellular drug resistance, the activation of various apoptotic parameters in leukemic cells from 50 children with ALL was studied after in vitro exposure with 4 important drugs in ALL therapy (prednisolone, vincristine, l-asparaginase, and daunorubicin). Exposure to each drug resulted in early induction of phosphatidylserine (PS) externalization and mitochondrial transmembrane (Deltapsim) depolarization followed by caspase-3 activation and poly(ADP-ribose) polymerase (PARP) inactivation in the majority of patients. For all 4 drugs, a significant inverse correlation was found between cellular drug resistance and (1) the percentage of cells with PS externalization (<.001 < P <.008) and (2) the percentage of cells with Deltapsim depolarization (.002 < P <.02). However, the percentage of cells with caspase-3 activation and the percentage of cells with PARP inactivation showed a significant inverse correlation with cellular resistance for prednisolone (P =.001; P =.001) and l-asparaginase (P =.01; P =.001) only. This suggests that caspase-3 activation and PARP inactivation are not essential for vincristine- and daunorubicin-induced apoptosis. In conclusion, resistance to 4 unrelated drugs is associated with defect(s) upstream or at the level of PS externalization and Deltapsim depolarization. This leads to decreased activation of apoptotic parameters in resistant cases of pediatric ALL.
Chiral 1,4-benzodiazepine. VII. Cyclization rates of 2-(n-alpha-ammoniumacyl)-amino-5-chloro-benzophenones in the chiral 1,4-benzodiazepin-2-ones. (1975)

Cyclisation rates of some S-alpha-amino acid derivatives (I--VII) into chiral 1,4-benzodiazepin-2-ones were determined under physiological-like conditions (pH, temperature) and plotted against pKa values of the corresponding alpha-amino acids. No correlation between k, i.e. t1/2 values, of the acidic precursors, and pharmacodynamic activity, as determined by some standard tests, were observed, however. Unambiguity of cyclisation, and its t1/2 values reveal benefit for physico-chemical properties of the investigated acyclic precursors as transport-forms of the chiral 1,4-benzodiazepin-2-ones with prolonged pharmacological activity.

Cuts Both Ways: Proteases Modulate Virulence of Enterohemorrhagic <i>Escherichia coli</i> (2019)

Enterohemorrhagic <i>Escherichia coli</i> (EHEC) is a major cause of foodborne gastrointestinal illness. EHEC uses a specialized type III secretion system (T3SS) to form attaching and effacing lesions in the colonic epithelium and outcompete commensal gut microbiota to cause disease. A recent report in <i>mBio</i> (E. A. Cameron, M. M. Curtis, A. Kumar, G. M. Dunny, et al., mBio 9:e02204-18, 2018, https://doi.org/10.1128/mBio.02204-18) describes a new role for gut commensals in potentiating disease caused by EHEC. Proteases produced by EHEC and the prevalent human commensal <i>Bacteroides thetaiotaomicron</i> cleave proteins in the EHEC T3SS translocon that modulate T3SS function. <i>B. thetaiotaomicron</i> protease activity promotes translocation of bacterial effectors required for lesion formation. These results describe a new role for the microbiota in gastrointestinal disease that could uncover future treatments to prevent the spread of gastroenteritis.
Acromegaly update--etiology, diagnosis and management. (1987)

Acromegaly is a disease with unique clinical manifestations. Its confirmatory diagnosis, however, requires basal and dynamic tests of growth hormone secretion. The measurement of circulating levels of somatomedin C has been a valuable addition to the diagnostic armamentarium. We review the etiology of acromegaly, with particular reference to the different histochemical and ultrastructural forms of somatotropic adenomas and their respective clinical behaviors. Ectopic sources of growth hormone-releasing hormone and of growth hormone itself are now well-recognized, though unusual, causes of acromegaly. The treatment of acromegaly is often problematic and far from uniformly successful. Initial enthusiasm for the results of surgical treatment has now been tempered by reports of increasing rates of recurrence on long-term follow-up. The roles of irradiation and pharmacotherapy are reviewed with particular emphasis on the use of bromocriptine, which has added a new dimension to the control of the somatic and metabolic manifestations of hypersomatotropism. Studies have been done recently using a long-acting somatostatin analog with encouraging results.
<title>Multiple-Frequency Heterodyne Correlation Radiometry</title> (1976)

A heterodyne correlation radiometer is proposed for the sensitive detection of radiating species whose Doppler shift is known, but whose presence we wish to affirm. Such radiation (which may be actively induced) can arise, for example, from remote molecular emitters, impurities and pollutants, trace minerals, chemical agents, or a general multiline source. A radiating sample of the species to be detected is physically made a part of the laboratory receiver, and serves as a kind of frequency-domain template with which the remote radiation is correlated, after heterodyne detection. The system is expected to be especially useful for the detection of sources whose radiated energy is distributed over a large number of lines, with frequencies that are not necessarily known. Neither a stable nor a tunable local oscillator is required. It is shown that the minimum detectable power is expressible in a form similar to that for conventional heterodyning (for both quantum-noise-limited and Johnson-noise-limited detectors). The notable distinction is that the performance of the proposed system improves with increasing number of remotely radiating signal lines and increasing locally produced radiation power. Performance degradation due to undesired impurity radiation is considered and shown not to be a problem in general. The technique should be applicable over a broad frequency range from the microwave to the optical, with its most likely use in the infrared.
Micromachined Jet Arrays for Liquid Impingement Cooling of VLSI Chips (2002)

Two-phase cooling of VLSI chips with microjet heat sinks promises a new, effective heat removal method. Microjet arrays can achieve improved temperature uniformity in the presence of chip hotspots. This paper describes the development and assesses the performance of micromachined single and multi-jet arrays with orifice diameters less than 100 m. The devices were tested in a confined geometry with a dedicated heater test chip, as well as in an open geometry with a standard 1 cm 2 Intel test chip. In the confined geometry, a 76 m diameter four-jet array at a flow rate of 8 ml/min removed over 90 W/cm 2 . Experimental comparisons of microjet and microchannel performance show that microjets have improved thermal uniformity, offer a significantly more stable two-phase region, and do not exhibit superheating. These advantages suggest that microjet arrays are the preferred micro heat sinks for effective device cooling.
Spatial regularization of the inverse problem of electrocardiography: noncontact mapping of unipolar and bipolar endocardial electrograms (2002)

An adaptive spatial regularization method was developed and applied to solving the inverse problem of electrocardiography for reconstruction of endocardial electrograms based on measurements obtained with a noncontact multielectrode cavitary probe. The performance of the method was assessed in reconstructing unipolar as well as bipolar endocardial surface electrograms. The adaptive method provides superior results compared to zero-order Tikhonov regularization method.
On the Relationships among Optimal Symmetric Fix-Free Codes (2012)

Symmetric fix-free codes are prefix condition codes in which each codeword is required to be a palindrome. Their study is motivated by the topic of joint source-channel coding. Although they have been considered by a few communities they are not well understood. In earlier work we used a collection of instances of Boolean satisfiability problems as a tool in the generation of all optimal binary symmetric fix-free codes with n codewords and observed that the number of different optimal codelength sequences grows slowly compared with the corresponding number for prefix condition codes. We demonstrate that all optimal symmetric fix-free codes can alternatively be obtained by sequences of codes generated by simple manipulations starting from one particular code. We also discuss simplifications in the process of searching for this set of codes.
