GuideLoc: UAV-Assisted Multitarget Localization System for Disaster Rescue (2017)

Locating trapped targets using the signals of wireless devices such as mobile phones carried by targets is increasingly becoming the preferred scheme for disaster rescue. However, the accuracy of radio-localization technology currently adopted in the rescue is not high enough. To solve such problems, researchers proposed the approaches of Warwalking or Wardriving. However, both approaches are all limited by application scenarios. This paper proposes GuideLoc, a highly efficient aerial wireless localization system, which uses the target guiding technology based on region division. GuideLoc allows an unmanned aerial vehicle (UAV) to fly over a target device and provide position coordinates of the UAV as the target location information. During the process of positioning targets, based on the result of regional division, GuideLoc uses a number of fixed antennas to get the received signal strength indicator (RSSI) and angle of arrival (AOA) information of the target and estimates the target location using the information and correspondingly controls the UAV to fly towards the target. Averaging method is also applied for determining coordinates of the target. Experiment results show that GuideLoc can in short time achieve 2.7-meter positioning accuracy in average. Compared with other wireless localization methods using UAVs proposed in the literature, it shortened the flight distance by more than 50%. In addition, energy efficiency is also improved significantly.
Pathogenic Diversity of <i>Phytophthora sojae</i> in Ohio Soybean Fields (2003)

Problems with early season soybean stand establishment, and an increase in incidence of Phytophthora root and stem rot caused by Phytophthora sojae, prompted a reassessment of the pathogen population in Ohio. Earlier studies had indicated a potential for pathogen adaptation to commonly deployed Rps genes in soybeans. Fifty-seven fields, part of an earlier study in 1990 and 1991, along with 29 additional fields were sampled in either 1997 or 1999. Two soybean cultivars, Sloan (rps) and Resnik (Rps1k), were used as bait in a seedling bioassay to isolate P. sojae from the soil samples. P. sojae was recovered from 82 of the 86 fields sampled. Of the 429 isolates recovered from these soils, 325 and 104 were baited with soybean cultivars Sloan and Resnik, respectively. The P. sojae population in Ohio increased in the number of pathotypes (races) as well as in complexity since the earlier surveys. There were 72 and 202 pathotypes identified on 8 and 13 Rps gene differentials, respectively, in the current study. When the data were compared by location, 96, 65, 73, 78, 51, and 52% of the locations had at least one isolate with virulences to Rps1a, Rps1b, Rps1c, Rps1k, Rps3a, and Rps6, respectively. The mean complexity, the number of susceptible interactions on 8 differentials, increased from 3.01 to 4.06 between 1991 and 1997/1999. In addition, the pathogenic diversity as measured by the Shannon index increased from 2.71 to 3.28 for isolates recovered from the 57 fields sampled in both surveys. Producers whose fields were sampled were surveyed to determine if changes in the P. sojae population could be linked with production practices. There was a significant association between (P ≤ 0.05) reduced tillage practices and the presence of isolates that had virulence to Rps1k; reduced tillage fields also had isolates with virulence to a greater number of differentials. Due to the percentage of isolates that have virulence to many of the Rps genes, it is questionable how long a single Rps gene or several stacked Rps genes will remain viable disease management tools for P. sojae, unless a novel Rps gene is identified.

Preparation, Resolution, and Absorption and Circular Dichroism Spectra of [Co(en)<i>n</i>{NH2CH2CH2P(CH3)2}3−<i>n</i>]3+ and the Related Complexes, and the Absolute Configuration of (+)589-<i>fac</i>-[Co{NH2CH2CH2P(CH3)2}3]3+ Determined by X-Ray Analysis (1981)

Abstract A series of complexes, [Co(en)n{NH2CH2CH2P(CH3)2}3−n]3+ (en=ethylenediamine, n=0,1,2) and three bis(ethylenediamine)cobalt(III) complexes of the related ligands, NH2CH2CH2P(C6H5)2, (S)-NH2CH(CH3)CH2P(C6H5)2, and rac-NH2CH2CH2P(C4H9)(C6H5) were prepared and resolved (or separated) into optical isomers, and their absorption and circular dichroism spectra were recorded. The molecular structure and the absolute configuration of (+)589-fac-[Co{NH2CH2CH2P(CH3)2}3]Br3·3H2O were determined by X-ray analysis. The crystals are lemon-yellow, orthorhombic, a=26.501(8), b=9.573(4), c=10.081(5) Å, space group P212121, z=4. The Co atom is surrounded by 3P and 3N in the facial manner with the average distances of 2.237 and 2.041 Å, respectively. The absolute configuration of the complex ion is Δ. The chelate rings are puckered and chiral to form a pseudo λ gauche conformation.
Chemo-immunotherapy with levamisole in metastatic breast carcinoma: a controlled clinical trial. (1980)

A randomized prospectively controlled trial assessing the value of levamisole in patients receiving chemotherapy for metastatic carcinoma of the breast is reported. Patients randomized to the chemo-immunotherapy group received levamisole 2.5 mg/kg orally for 2 consecutive days each week while off chemotherapy, which consisted of the standard regiment of cyclophosphamide, methotrexate and 5-fluorouracil (CMF). Seventy-seven patients were assessable, 38 patients in the chemo-immunotherapy arm and 39 patients in the chemotherapy alone arm. Of the 38 patients in the chemo-immunotherapy, 18 (47.3%) experienced a complete or partial response compared to 18 (46.1%) in the chemotherapy alone group. The median duration of response in both groups of patients was approximately 15 months. The median duration of survival in the chemo-immunotherapy group was 21 months and in the chemotherapy alone group has not yet been reached but is at least 21 months. Levamisole was generally well tolerated, but in the dosage and scheduling did not appear to improve the results of the chemotherapy. It is suggested that efforts should be directed to increasing the complete response rate with chemotherapy and radiotherapy to provide the best setting for immunotherapy trials.
Predictors of mortality and morbidity in patients with chronic heart failure (2005)

In a large contemporary CHF population, including patients with preserved and decreased left ventricular systolic function, routine clinical variables can discriminate risk regardless of EF. Diabetes was found to be a surprisingly strong independent predictor. These models can stratify risk and help define how patient characteristics relate to clinical course.
Creating a culture of health: evolving healthcare systems and patient engagement (2016)

We all recognize that today's healthcare megatrends are challenging to people, practitioners, scientists, healthcare systems, governments and life science companies. This is particularly true for the increasingly frequent chronic conditions in which these trends coalesce. 1 How do we handle the complexity of delivering personalized medicine that reflects individual preferences while taking advantage of the evidence base? 2 What is the answer for the rising cost of both the proliferation of treatments effective for chronic conditions 3 and those of conducting clinical research? 4 Finally, how do we address the new business challenge for healthcare providers to move away from paying for volumes of services in favor of paying for the value of health outcomes achieved by the patients they serve who have lifelong chronic health problems? t is critical for systems wishing to help patients and their communities optimize health to learn to partner with patients in all aspects of care re-design, from planning through delivering services and evaluating outcomes. Moreover, the focus of this partnership will be on improving health, including the contribution that healthcare services make. Methods that facilitate the systematic inclusion and amplification of the patient voice, such as patient reported outcome measures, help us change the focus of the conversation. n this paper, we propose an approach that supports a shift towards a culture of health by facilitating new conversationsbases for culture and cultural change-among all stakeholders involved. We will provide an example of a learning health system that promotes specific changes that are catalyzed through sharing information and holding conversations among stakeholders to promote healthier lives for people who are living with chronic disease.
Real Threats to Your Data Bills (2014)

Secure mobile data charging (MDC) is critical to cellular network operations. It must charge the right user for the right volume that (s)he authorizes to consume (i.e., requirements of authentication, authorization, and accounting (AAA)). In this work, we conduct security analysis of the MDC system in cellular networks. We find that all three can be breached in both design and practice, and identify three concrete vulnerabilities: authentication bypass, authorization fraud and accounting volume inaccuracy. The root causes lie in technology fundamentals of cellular networks and the Internet IP design, as well as imprudent implementations. We devise three showcase attacks to demonstrate that, even simple attacks can easily penetrate the operational 3G/4G cellular networks. We further propose and evaluate defense solutions.

Pregnane X Receptor (PXR), Constitutive Androstane Receptor (CAR), and Benzoate X Receptor (BXR) Define Three Pharmacologically Distinct Classes of Nuclear Receptors (2002)

The NR1I subfamily of nuclear receptors contains a phylogenetically diverse array of receptors related to the mammalian pregnane X receptor (PXR) (NR1I2) and constitutive androstane receptor (CAR) (NR1I3). We have carried out an extensive comparative analysis of this subgroup with representatives from fish, birds, amphibians, and mammals. Four novel receptors were isolated from fish, dog, pig, and monkey for this study and combined with a previously reported set of related receptors including human PXR, rabbit PXR, mouse PXR, chicken CXR, frog benzoate X receptors (BXRalpha, BXRbeta), and human and mouse CAR. A broad range of xenobiotics, steroids, and bile acids were tested for their ability to activate the ligand binding domain of each receptor. Three distinct groups of receptors were identified based on their pharmacological profiles: 1) the PXRs were activated by a broad range of xenobiotics and, along with the mammalian PXRs, included the chicken and fish receptors; 2) the CARs were less promiscuous, had high basal activities, and were generally repressed rather than activated by those compounds that modulated their activity; and 3) the BXRs were selectively activated by a subset of benzoate analogs and are likely to be specialized receptors for this chemical class of ligands. The PXRs are differentiated from the other NR1I receptors by a stretch of amino acids between helices 1 and 3, which we designate the H1-3 insert. This insert was present in the mammalian, chicken, and fish PXRs but absent in the CARs and BXRs. Modeling studies suggest that the H1-3 insert contributes to the promiscuity of the PXRs by facilitating the unwinding of helices-6 and -7, thereby expanding the ligand binding pocket.
Strong password authentication protocols (2010)

Password-based authentication is the protocol that two entities share a password in advance and use the password as the basic of authentication. Existing password authentication scheme can be categorized into two types: weak-password authentication schemes and strong-password authentication schemes. In general, strong-password authentication protocols have the advantages over the weak-password authentication schemes in that their computational overhead are lighter, designs are simpler, and implementation are easier, and therefore are especially suitable for some constrained environments. In this paper, we propose a strong password authentication scheme (SPAS) based on previous research. The SPAS is resistant to Dos attacks, replay attacks and stolen-verifier attacks. It expects SPAS can be employed in application scenarios where lightweight and secure user authentication scheme is required.
Bronchoalveolar lavage fluid cell counts in cryptogenic fibrosing alveolitis and their relation to therapy. (1980)

Bronchoalveolar lavage was used to sample inflammatory cells from the lungs of 51 patients with cryptogenic fibrosing alveolitis (CFA) (24 smokers, 12 ex-smokers, and 15 non-smokers). The smokers with CFA have been compared with 15 smoking control subjects in whom there was no radiographic abnormality or clinical evidence of chronic bronchitis. Significantly lower volumes of lavage fluid were recovered from the smokers with CFA (p < 0.001) and the fluid contained lower percentages of macrophages (p < 0.01), reflecting increased percentages of eosinophils (p < 0.001) and neutrophils (p < 0.01). Similar changes were seen in the ex-smokers and non-smokers. There was also an increase in the percentages of lymphocytes when the whole group of CFA patients was compared with the control subjects (p less than or equal to 0.05). No significant differences were found when patients with "lone" CFA were compared with those having associated systemic disease. The only feature distinguishing smokers from non-smokers with CFA was the presence of pigmented cytoplasmic inclusions in the macrophages from the smokers (p < 0.001). However, there were lower numbers of pigmented macrophages in the smoking CFA patients by comparison with the control subjects suggesting either a change in phagocytic capacity or turnover rate in this disease. Profiles of differential cell counts in individual patients showed that increases of eosinophils over 3% or neutrophils over 4% or both with lymphocyte counts of less than 11% related to a poor clinical response to corticosteroids, but lymphocyte percentages greater than 11% related to improvement (p < 0.05).
Synthesis and characterization of new chiral liquid crystalline polyacrylates from L-isoleucine (2002)

The synthesis of chiral side chain liquid crystalline polyacrylates with a two-stereogenic centre from L-α-aminoacid is described. The chiral tail is 2-chloroalcohol obtained from L-isoleucine and the spacer group has either four or eleven methylene units. The mesogenic moiety is derived from phenyl benzoate. The stereochemistry of the key intermediate (2S,3S)-(+)-4- [1-(2-chloro-3-methyl)pentyloxy]phenyl benzoate (6) obtained by a Mitsunobu reaction was established by single crystal X-ray analysis. This result indicates that the nucleophilic displacement of chiral diazonium salts proceeds with overall retention of configuration. The liquid crystalline behaviour of polyacrylates P13 and P14 was investigated by DSC, optical microscopy, small angle X-ray scattering and depolarized light scattering. The polyacrylate P13, with eleven methylene units in the spacer, exhibits a chiral smectic A phase whereas the polyacrylate P14, with a spacer containing four methylene units, displays a chiral nematic phase.
Double-Rotor Induction Motor (1969)

The double-rotor induction motor differs from a drag-cup motor in that the rotor is closed at both ends, necessitating the pivoting of the core inside the rotor. Since the core can carry current and is free to rotate, its characteristics affect the speed-torque characteristics of the rotor. The analysis of such a motor, including spatial harnonics, is outlined and it is shown that, in general, the core reduces the torque-to-inertia ratio of the rotor and that a low-loss core is necessary for good performance.

Using C60 molecules for deep carbonization of rhenium in ultrahigh vacuum (1997)

The adsorption of C60 molecules on the surface of a rhenium ibbon heated to 1800 K is investigated quantitatively. It is found that the C60 molecules are adsorbed without reflection and then dissociate, and the carbon formed in the process is dissolved in the bulk of the rhenium to the limit of solubility. Then a graphite monolayer forms on the rhenium surface, and the dissociation of the C60 molecules stops. It is shown that the C60 molecules can be used as an effective carbonizing object on metals in ultrahigh vacuum.

Sterile Filtration of NanoCrystal™ Drug Formulations (1997)

A Nano Crystal™ dispersion of the iodinated x-ray contrast agent iodipamide was prepared by wet milling the drug substance in the presence of Pluronic® F127 stabilizer. The mean particle size of the formulation was 98 nm and all drug particles in the formulation were smaller than 220 nm as determined by dynamic light scattering. Approximately 1 liter of dispersion was filtered through a sterile 0.2-μm disposable capsule filter (Supor® 200 DCF™, 0.I m2 effective filtration area [EFA], Gelman Sciences) to condition the capsule. No drug concentration or size distribution changes were detected after the filtration process. The microbiological validation tests were performed using Pseudomonas diminuta organisms to challenge the capsule under simulated worst-case process conditions. The results showed that the Supor 200 DCF was able to retain 100% Pseudomonas diminuta organisms (≥107 organisms per cm2 of effective filtration area). Thus, this study demonstrated that terminal filtration is a feasible process to sterilize Nano Crystal™ drug dispersions that may be chemically or physically unstable at elevated temperatures and thus not amenable to terminal heat sterilization.

Metal-binding site in a class I tRNA synthetase localized to a cysteine cluster inserted into nucleotide-binding fold. (1993)

The 10 class I aminoacyl-tRNA synthetases share a common N-terminal nucleotide-binding fold. Idiosyncratic polypeptide insertions into this fold introduce residues important for activity, including those that interact with the tRNA acceptor helix. The class I Escherichia coli methionyl-tRNA synthetase (L-methionine:tRNA(Met) ligase, EC 6.1.1.10), a 676-amino acid homodimer, was shown previously by others to contain zinc and to have an activity dependent on its presence. We show here by atomic absorption spectroscopy and zinc titrations the presence of 1 mol of zinc per polypeptide. Replacement of zinc with cobalt yields an active enzyme with a visible absorption spectrum characteristic of tetrahedral coordination to sulfur ligands and an intense metal-to-sulfur charge-transfer band at 340 nm. Mapping of the metal-binding site by zinc blotting of recombinant and proteolytic fragments localized the site to a polypeptide insertion between two strands and a beta-sheet in the N-terminal nucleotide-binding fold that contains the catalytic site. Beginning at Cys-145, this insertion contains a Cys-Xaa2-Cys-Xaa9-Cys-Xaa2-Cys motif. Site-directed substitution of these cysteines with serines yielded proteins that were stable but generally devoid of activity. With this result there is now at least one example of a class I and of a class II E. coli tRNA synthetase with a metal-binding domain important for activity inserted into the catalytic domain.
Highly Substituted 2-Amido-furans From Rh(II)-Catalyzed Cyclopropenations of Ynamides (2009)

Rh(II)-catalyzed cyclopropenations of ynamides are described. Although an actual amido-cyclopropene intermediate may not be involved, these reactions provide a facile entry to highly substituted 2-amido-furans, thereby formerly constituting a [3 + 2] cycloaddition. An application of these de novo 2-amido-furans in N-tethered intramolecular [4 + 2] cycloadditions is also illustrated, leading to dihydroindoles and tetrahydroquinolines.
