Delay-Aware Energy-Efficient Routing towards a Path-Fixed Mobile Sink in Industrial Wireless Sensor Networks (2018)

Wireless sensor networks (WSNs) involve more mobile elements with their widespread development in industries. Exploiting mobility present in WSNs for data collection can effectively improve the network performance. However, when the sink (i.e., data collector) path is fixed and the movement is uncontrollable, existing schemes fail to guarantee delay requirements while achieving high energy efficiency. This paper proposes a delay-aware energy-efficient routing algorithm for WSNs with a path-fixed mobile sink, named DERM, which can strike a desirable balance between the delivery latency and energy conservation. We characterize the object of DERM as realizing the energy-optimal anycast to time-varying destination regions, and introduce a location-based forwarding technique tailored for this problem. To reduce the control overhead, a lightweight sink location calibration method is devised, which cooperates with the rough estimation based on the mobility pattern to determine the sink location. We also design a fault-tolerant mechanism called track routing to tackle location errors for ensuring reliable and on-time data delivery. We comprehensively evaluate DERM by comparing it with two canonical routing schemes and a baseline solution presented in this work. Extensive evaluation results demonstrate that DERM can provide considerable energy savings while meeting the delay constraint and maintaining a high delivery ratio.

The construction of new proteins: V. A template‐assembled synthetic protein (TASP) containing both a 4‐helix bundle and β‐barrel‐like structure (1989)

The construction of a template-assembled synthetic protein (TASP) designed to contain both a 4-helix bundle and a beta-barrel as two folding "domains" is described. For the de novo design of proteins, amphiphilic helices (alpha) and beta-sheets (beta) are covalently attached to a template peptide (T) carrying functional side chains suitably oriented to promote intramolecular folding of the secondary structure blocks into a characteristic packing arrangement, i.e., T8-(4 alpha)(4 beta). The design of this new macromolecule was assisted by computer modeling, which suggested a low-energy conformation with tight hydrophobic packing of the secondary structure subunits. Solid-phase synthesis of the "two-domain" TASP molecule was achieved using orthogonal protection techniques. The solution properties as well as circular dichroism (CD) and infrared spectroscopy (IR) data under various experimental conditions are consistent with the folded conformation suggested by modeling.

Molecular physiology of CFTR Cl- channels in heart. (1994)

Recent electrophysiological data suggests a number of similarities in the properties of cAMP-dependent Cl- channels in heart and cAMP-dependent Cl- channels encoded by the cystic fibrosis transmembrane conductance regulator (CFTR) gene product in various epithelial cells. We tested the hypothesis that cAMP-dependent Cl- channels in heart may be due to cardiac expression of CFTR by amplification and sequencing of several regions of CFTR from myocardial tissue derived from various species and areas of the heart. Regions corresponding to the first nucleotide binding domain (NBD1), transmembrane segments I-VI (TS I-VI), transmembrane segments VII-XII (TS VII-XII), and the regulatory domain (R domain) were amplified and sequenced from rabbit ventricle (see Fig. 1). Comparison of the known amino acid sequence of human epithelial CFTR with the deduced sequence from rabbit heart indicated deletion of exon 5 in the first cytoplasmic loop of TS I-VI suggesting that CFTR is an alternatively spliced isoform in rabbit ventricle. Outside of the alternatively spliced region, the heart CFTR Cl- channel isoform displayed greater than 95% identity to human epithelial CFTR Cl- channels. We have also compared the molecular distribution of the CFTR gene product to the distribution of cAMP-dependent Cl- channels in native cardiac myocytes derived from various species and areas of the heart. Amplification of regions corresponding to NBD1, R domain, and TS VII-XII from atrium and ventricle of guinea pigs, rabbit, and dog hearts exhibited a distribution which closely matched the distribution of cAMP-dependent Cl- channels assessed using electrophysiological techniques.(ABSTRACT TRUNCATED AT 250 WORDS)

Contemporary Diagnosis and Management of Systemic Mastocytosis (2007)

Systemic mastocytosis (SM) is a clonal disease of mast cells (MCs) and their progenitors. Clinical symptoms arise from MC-derived mediators and/or from local MC infiltration, which in rare cases can be aggressive or even devastating. The clinical presentation, course, and prognosis in SM are variable. The WHO discriminates the following disease variants: indolent SM (ISM), aggressive SM (ASM), SM with associated clonal hematological non–MC-lineage disease (AHNMD), and mast cell leukemia (MCL). The KIT mutation D816V is found in all SM categories, including SM-AHNMD, where the mutation is sometimes 162detectable in the AHNMD component of the disease. Other molecular defects are usually found in patients with SM-AHNMD, and reflect the nature of the associated malignancy. Therapeutic options in ISM include the use of antihis-tamines and other “mediator-targeting” drugs as well as bisphosphonates for those who develop osteoporosis. Patients with ASM are candidates for cytoreductive drugs (e.g., interferon-alpha or cladribine, 2CdA) or targeted drugs. Among the latter, imatinib works in the unusual patient, where no KIT mutations at codon 816 are found. For “codon 816 patients,” investigational therapies with new tyro-sine kinase inhibitors, such as midostaurin (PKC412) or dasatinib, may yield better results. For patients with rapidly progressing ASM or MCL, intensive chemotherapy and stem cell transplantation should be considered. In patients with SM-AHNMD, separate treatment plans for the SM-and AHNMD components of the disease need to be established. Examples are chemotherapy for AML in SM-AML, or imatinib in SM with concomitant FIP1L1/PDGFRA+ eosinophilic leukemia.
Temperature dependence of the magnetostriction of stress annealed Galfenol measured under tension (2010)

Galfenol (Fe100−xGax) is a relatively new, highly magnetostrictive active material with strains of about 330 ppm as a slow cooled single crystal and about 280 ppm as a highly textured polycrystal at x=∼18.4. Four main advantages over other materials are (1) Galfenol’s structural strength; (2) the ability of a single composition to operate over the temperature range of −269–+150 °C (for stress annealed rods, higher for unannealed rods); (3) the ability of stress annealed Galfenol to provide full performance under stresses ranging from at least −160 to +30 MPa (compressive stresses are negative); and (4) the ability to use standard metal working techniques. The magnetostriction and magnetization of two stress annealed, highly textured Fe81.6Ga18.4 rods were measured at temperatures between −50 and +100 °C and tensile stresses of approximately +1, +10, +20, +30, and +40 MPa. Measurements were taken inside an environmental chamber using a spring to supply the stress. A stress change of about 2 MPa between −50 and +100 °C was typical. The saturation magnetostriction is nearly independent of stress up to 20 MPa, drops only slightly at 30 MPa, and falls off rapidly at 40 MPa. At a given stress, the saturation magnetostriction decreases roughly linearly at ∼0.3×10−6/°C.
DNA methylation in breast cancer. (2001)

Like all cancers, breast cancer is considered to result in part from the accumulation of multiple genetic alterations leading to oncogene overexpression and tumor suppressor loss. More recently, the role of epigenetic change as a distinct and crucial mechanism to silence a variety of methylated tissue-specific and imprinted genes has emerged in many cancer types. This review will briefly discuss basic aspects of DNA methylation, recent advances in DNA methyltransferases, the role of altered chromatin organization and the concept of gene transcriptional regulation built on methylated CpGs. In particular, we discuss epigenetic regulation of certain critical tumor suppressor and growth regulatory genes implicated in breast cancer, and its relevance to breast cancer diagnosis, prognosis, progression and therapy.

BDNF val(66)met Genotype is Associated With Greater Brain Atrophy After Stroke (2018)

Background: Genetic factors may be useful to understand differences in outcomes post-stroke.We studied an imaging measure of brain atrophy in relation to two genotypes that may be associated with differences in stroke recovery, the val met genotype for brain-derived neurotrophic factor (BDNF) and the ApoE e4 genotype.Each genotype has been associated with brain atrophy in nonstroke populations.The current study hypothesized that each genotype is associated with brain atrophy after stroke. Methods:The ICARE Study examined behavioral outcomes after stroke in relation to motor therapies.Of 361 ICARE enrollees, genetic and neuroimaging data were available in 127.The volume of the ventricles and the brain were measured, and brain atrophy expressed as the Ventricle-Brain Ratio (VBR).For MRI scans, VBR was first extracted from the scans using ALVIN then manually refined.For CT scans, VBR was extracted manually.All VBR measurements were verified by a neuroimaging expert.VBR was examined in relation to the two genotypes of interest, BDNF val met and ApoE e4, controlling for the 3 covariates employed in ICARE: motor deficits, enrollment site, and time post-stroke at study entry.Results: There were 61 MRI and 66 CT scans.These were acquired 511 days post-stroke, which did not vary according to either genotype.Median ventricle volume=26.1 cc; brain volume=1,163 cc; and VBR=0.024.The BDNF val met genotype was present in 23 subjects; ApoE e4, in 41; both were in HW equilibrium.Presence of the BDNF val met genotype was associated with greater atrophy: median VBR increased 1.97-fold when this genotype was present vs. absent (p=0.01),controlling for above covariates; and remained significant (p=0.04)when also controlling for age.This BDNF gene-imaging correlate did not extend to gene-behavioral findings.The ApoE e4 genotype was not related to VBR (p=0.88).
Ultrafast and highly sensitive photodetectors fabricated on high-energy nitrogen-implanted GaAs (2003)

We have fabricated and tested metal–semiconductor–metal (MSM) photodetectors based on nitrogen-ion-implanted GaAs. Nitrogen ions with energy of 700 and 880 keV, respectively, were implanted into epitaxial GaAs films at an ion concentration of 3×1012 cm−2. Ti/Au MSM photodetectors with 1-μm-wide fingers were fabricated on top of the implanted GaAs. In comparison to low-temperature-grown GaAs photodetectors, produced in parallel in identical MSM geometry, the 880 keV N+-implanted photodetectors exhibited almost two orders of magnitude lower dark current (10 nA at 1 V bias) and the responsivity more than doubled (&gt;20 mA/W at 20 V bias). Illumination with 100-fs-wide, 810 nm wavelength laser pulses, generated ∼2.5-ps-wide photoresponse signals with amplitudes as high as 2 V. The 2.5 ps relaxation time was the same for both the ion-implanted and low-temperature-grown devices and was limited by the MSM capacitance time constant.

Modeling gender dynamics in intra and interpersonal interactions during online collaborative learning (2019)

There has been long-standing stereotypes on men and women's communication styles, such as men using more assertive or aggressive language and women showing more agreeableness and emotions in interactions. In the context of collaborative learning, male learners often believed to be more active participants while female learners are less engaged. To further explore gender differences in learners communication behavior and whether it has changed in the context of online synchronous collaboration, we examined students interactions at a sociocognitive level with a methodology called Group Communication Analysis (GCA). We found that there were no significant differences between men and women in the degree of participation. However, women exhibited significantly higher average social impact, responsivity and internal cohesion compared to men. We also compared the proportion of learners interaction profiles, and results suggest that women are more likely to be effective and cohesive communicators. We discussed implications of these findings for pedagogical practices to promote inclusivity and equity in collaborative learning online.

Emission Factors of Black Carbon and Co-pollutants from Diesel Vehicles in Mexico City (2017)

Abstract. Diesel-powered vehicles are intensively used in urban areas for transporting goods and people but can substantially contribute to high emissions of black carbon (BC), organic carbon (OC), and other gaseous pollutants. Strategies aimed at controlling mobile emissions sources thus have the potential to improve air quality as well as help mitigate impacts of air pollutants on climate, ecosystems, and human health. However, in developing countries there are limited data on the BC and OC emission characteristics of diesel-powered vehicles and thus there are large uncertainties in the estimation of the emission contributions from these sources. We measured BC, OC and other inorganic components of fine particulate matter (PM), as well as carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), ethane, acetylene, benzene, toluene, and C2-benzenes under real-world driving conditions of 20 diesel-powered vehicles encompassing multiple emission level technologies in Mexico City with the chasing technique using the Aerodyne mobile laboratory. Average BC emission factors ranged from 0.41–2.48 g/kg-fuel depending on vehicle type. The vehicles were also simultaneously measured using the cross-road remote sensing technique to obtain the emission factors of nitrogen oxide (NO), CO, total hydrocarbons, and fine PM, thus allowing the inter-comparison of the results from the two techniques. There is overall good agreement between the two techniques and both can identify high and low emitters but substantial differences were found in some of the vehicles, probably due to the ability of the chasing technique to capture a larger diversity of driving conditions in comparison to the remote sensing technique. A comparison of the results with the US-EPA MOVES-2014b model showed that the model underestimates CO, OC, and selected VOC species whereas there is better agreement for NOx and BC. Larger OC / BC ratios were found in comparison to ratios measured in California using the same technique, further demonstrating the need for using locally-obtained diesel-powered vehicle emission factors database in developing countries in order to reduce the uncertainty in the emissions estimates and to improve the evaluation of the effectiveness of emissions reduction measures.

Multiplexing of sensors based on fibre-optic differential delay RF filters (1988)

The letter describes frequency-division multiplexing of intensity modulation filtering sensors. The feasibility of the scheme was demonstrated by multiplexing a pressure sensor, measured over the range 0–500 psi, and a temperature sensor, measured over the range 10–40°C.
Magnetooptical properties of Co-SiO2 granular films (2008)

The structural, optical, and magnetooptical properties of Co-SiO2 granular films are studied. It is found that the magnetooptical response is considerably enhanced in samples with a metal component concentration close to the percolation threshold. The Co nanogranules formed in the SiO2 matrix exhibit ferromagnetic properties and are ordered into the fcc structure, which is confirmed by magnetooptical investigations. The magnetooptical properties of nanocomposites are simulated in the effective-medium approximation. It is shown that the singularities found in the magnetooptical spectra are related to the excitation of plasmon resonances in granular films.
Ferric chloride flocculation for nonflocculating beef extract preparations (1984)

The addition of 2.5 mM ferric chloride to 0.5% beef extract solution at pH 3.5 was found to be highly efficient in the recovery of seeded poliovirus type 1 (Sabin) or indigenous viruses from environmental samples. This method was extremely useful to reconcentrate viruses from beef extract solutions that did not flocculate at pH 3.5.
