Accurate <sup>13</sup>C and <sup>15</sup>N Chemical Shift and <sup>14</sup>N Quadrupolar Coupling Constant Calculations in Amino Acid Crystals:  Zwitterionic, Hydrogen-Bonded Systems (2003)

EIM (embedded ion method), cluster, combined EIM/cluster, and isolated molecule (13)C and (15)N chemical shielding and quadrupolar coupling constant (QCC) calculations at the B3LYP level with D95**, D95++**, 6-311G**, and 6-311+G** basis sets were done on the amino acids l-alanine, l-asparagine monohydrate, and l-histidine monohydrate monohydrochloride and on the two polymorphs α and γ glycine. The intermolecular interactions that are present in the amino acid crystals are accounted for in the EIM calculations by a finite array of point charges calculated from Ewald lattice sums and in the cluster calculations by a shell of neighboring molecules or molecular fragments. The combined EIM/cluster calculations utilize a cluster of molecules inside an EIM point charge array. The theoretical (13)C and (15)N principal shielding values for the amino acids studied are compared to the experimental principal shift values. In addition, theoretical CN bond orientations in the chemical shift principal axis system (PAS) are compared to the experimental orientations obtained from (13)C-(14)N dipolar couplings. The theoretical QCC at the nitrogen positions are compared to experimental (14)N QCC principal values reported in the literature. The carbon and nitrogen theoretical chemical shielding, the C-N orientations, and the QCCs from the ab initio calculations show improved agreement with the experimental values when the intermolecular interactions are accounted for by EIM or cluster calculations. The EIM (13)C shielding calculations are found to give better agreement with the experimental values than cluster (13)C shielding calculations. However, to achieve good agreement between the theoretical (14)N QCC and the (15)N principal shielding values with the respective experimental values, both intermolecular electrostatic and covalent interactions have to be included explicitly in the EIM/cluster calculations.
Direction of wave propagation in the cochlea for internally excited basilar membrane (2012)

Otoacoustic emissions are an indicator of a normally functioning cochlea and as such are a useful tool for non-invasive diagnosis as well as for understanding cochlear function. While these emitted waves are hypothesized to arise from active processes and exit through the cochlear fluids, neither the precise mechanism by which these emissions are generated nor the transmission pathway is completely known. With regard to the acoustic pathway, two competing hypotheses exist to explain the dominant mode of emission. One hypothesis, the backward-traveling wave hypothesis, posits that the emitted wave propagates as a coupled fluid-structure wave while the alternate hypothesis implicates a fast, compressional wave in the fluid as the main mechanism of energy transfer. In this paper, we study the acoustic pathway for transmission of energy from the inside of the cochlea to the outside through a physiologically-based theoretical model. Using a well-defined, compact source of internal excitation, we predict that the emission is dominated by a backward traveling fluid-structure wave. However, in an active model of the cochlea, a forward traveling wave basal to the location of the force is possible in a limited region around the best place. Finally, the model does predict the dominance of compressional waves under a different excitation, such as an apical excitation.

Improved Unequal-Clustering and Routing Protocol (2021)

Increased network lifetime is a desired property of low-powered and energy-constrained Internet of Things (IoT) devices that are deployed in wireless network environments. Clustering is used as a technique in multiple solutions to improve overall network lifetime. Further variants in the clustering process are defined to optimize the results. One such variant is equal clustering, where all the clusters have the same size. However, this approach suffers from the issue of nodes closer to the base station (BS) dying out earlier. As an alternative, unequal clustering is proposed, where clusters close to the BS are of smaller size; thus, cluster heads (CHs) consume a substantial proportion of their energy for being acting as data forwarding nodes. In this paper, we propose an unequal clustering approach with the BS at the center of a circular area. The size of each cluster is fixed and computed based on the node density of the area. The number of clusters increases from outwards to inwards towards the BS. The results show considerable performance gain over selected benchmark works.
Zirconium Oxide Modified Sulfonated Poly (Ether Ether Ketone) Membranes for Direct Methanol Fuel Cell Applications (2004)

In order to perform a critical analysis of the zirconium oxide effects in sulfonated poly(ether ether ketone) (SPEEK) membranes with two sulfonation degrees (SD), 71 and 87%, the characterization of composite membranes prepared with a systematic variation of the inorganic content is proposed. The method involves preparation of inorganic composite membranes with a wide range of properties which concern water swelling, chemical and thermal stability, methanol and water permeations and, finally, proton conductivity. A good balance between high proton conductivity, good chemical stability and low methanol permeability is reached for the SPEEK polymer with a 7.5% (w/w) ZrO2 content and SD=87%. Compared to NAFION ® 112, this membrane is 3-times more selective towards water/methanol permeation and has a similar proton conductivity (81 compared to 88 mS/cm).
Electron Microscope and Powder Metallurgy (1948)

More than 100 mutations in the Cu/Zn superoxide dismutase (SOD) gene have been found, accounting for about 20% of familial ALS (FALS). However, few have been identified in Chinese patients with FALS. We present a five-generation Chinese family with FALS with a rare mutation in exon 4 of the Cu/Zn SOD gene codon position 105, converting serine to leucine. Forty-seven family members including the proband were examined clinically; two affected persons had EMG and nerve conduction studies. Genomic DNA was extracted from peripheral blood leukocytes of the family members after informed consent. All five exons of the Cu/Zn SOD gene were amplified by polymerase chain reaction (PCR) and DNA sequencing was performed on purified products. Exon 4 of the Cu/Zn SOD gene was amplified from genomic DNA isolated from not only the family members but also from 50 unrelated healthy Chinese control subjects. A rare S105L mutation, which is heterozygous with C by T at position 1,125 of the coding sequence in exon 4 of the Cu/Zn SOD gene, was found in the proband and her affected elder brother. The clinical phenotype within the FALS patients in this family is relatively variable. The age at onset ranged from 32 to 65 years, with initial symptoms in either the upper or lower extremities in different family members. Two subjects aged 72 and 60 years remained asymptomatic until their death from other causes, although their offspring carrying the same mutation have already developed clinical evidence of the disease. The S105L mutation was identified in another seven asymptomatic family members, aged 7 to 59 years. It is concluded that the S105L mutation in exon 4 of the Cu/Zn SOD gene is pathogenic. The phenotype is characterized by relatively variable clinical symptoms, with incomplete penetrance.

Highly Defined Multiblock Copolypeptoids: Pushing the Limits of Living Nucleophilic Ring‐Opening Polymerization (2012)

Advanced macromolecular engineering requires excellent control over the polymerization reaction. Living polymerization methods are notoriously sensitive to impurities, which makes a practical realization of such control very challenging. Reversible-deactivation radical polymerization methods are typically more robust, but have other limitations. Here, we demonstrate by repeated (≥10 times) chain extension the extraordinary robustness of the living nucleophilic ring-opening polymerization of N-substituted glycine N-carboxyanhydrides, which yields polypeptoids. We observe essentially quantitative end-group fidelity under experimental conditions that are comparatively easily managed. This is employed to synthesize a pentablock quinquiespolymer with high definition.
[Immunocytochemical investigations of occluded saphenous vein grafts]. (1993)

Occluded saphenous vein aorto-coronary bypass grafts were investigated using two types of monoclonal antibodies, specific to either the muscle actin (HHF 35) or the macrophage (HAM 56). The early post operative occlusions of saphenous vein grafts were associated with the deposition of mural thrombi with little intimal proliferation. The late occlusions of saphenous vein grafts were associated with intimal fibrous proliferation without mural thrombus formation. Proliferated smooth muscle cells were a major constituent of intimal fibrous proliferation in both early and late occluded grafts. Macrophages were not detected in both groups. The proliferation of smooth muscle cells in the intima may play a role in the development of late occlusion, rather than the organizational process of accumulated mural thrombi.
Studies of New Aluminum Compounds for Antiperspirant Use. I (1967)

Synopsis--The synthesis of two new groups of alcohol-soluble aluminum compounds is described. They are (a) iron-free hydroxy aluminum alkoxy chlorides, and (b) new ring compounds called chlordioxalumolanes and chlordioxaluminanes. Three species were studied for use in aerosol antiperspirants. All three are mildly acid and appear to be com-pletely safe. Quantitative measurements of antiperspirant effectiveness of aerosols show effectiveness on a par with the best nonaerosol products in the case of two of the three com-pounds. Fabric destruction data are presented, as are stability and preliminary formulation studies. Aerosols prepared from all three form stable systems free from gelation and pre-cipitation at 7øC or 43øC.
Quantification of Hepatic Transcribing RNA Polymerase Molecules, Polyribonucleotide Elongation Rates and Messenger RNA Complexity in Fed and Fasted Rats (1978)

We have investigated the mechanisms by which the rate of preribosomal RNA and premessenger RNA synthesis are repressed during starvation of rats by a quantitative study of the transcriptional events in isolated nuclei and by complexity analysis of the cytoplasmic polyadenylated RNA. The transcriptional activities of form A and B DNA-dependent RNA polymerases, which produce preribosomal and premessenger RNA respectively, were distinguished by the use of α-amanitin. Form C activity was shown to be absent from nuclei as isolated here. Polyribonucleotide elongation rates and the number of transcribing RNA polymerase molecules per diploid genome were determined by UMP/uridine analysis of the alkali-digested, nascent RNA labelled from [3H]UTP during 1-min incubations at 22 °C in the presence and absence of α-amanitin. The inhibition of form-A-mediated preribosomal RNA synthesis in response to starvation and cycloheximide treatment could be entirely accounted for by a decrease in the polyribonucleotide elongation rate. No significant change in the number of transcribing enzyme molecules (about 20 × 103 per diploid genome) was detected. However on refeeding, the elongation rate was restored to normal and the number of transcribing form A molecules was elevated over the normal level. These results suggest that there are at least two modes of control acting on preribosomal RNA synthesis, one linked to protein synthesis and affecting the elongation rate, while a second regulates the number of form A RNA polymerase molecules transcribing the template. Form-B-mediated premessenger RNA synthesis responded to starvation by a decrease in the number of transcribing enzyme molecules from approximately 7 × 103 to 3 × 103 per diploid genome. This change was reversed on refeeding. Cycloheximide treatment did not affect premessenger RNA synthesis either via elongation or the number of transcribing enzyme molecules. The data indicate that premessenger RNA synthesis is controlled in this system at the level of RNA polymerase initiation by a mechanism not linked to protein synthesis. Hybridization analysis of the complexity of liver cytoplasmic polyadenylated mRNA from normal, starved and refed animals showed that three or four abundance classes were present in each case. No significant difference in mRNA populations between the dietary conditions was detected. More detailed examination of the most abundant class of mRNA confirmed this conclusion. The data show that although the number of transcribing form B molecules is reduced during starvation, the complexity and relative abundance of the mRNA synthesised does not change. The simplest explanation of these results is that, whilst the number of active genes does not change significantly during starvation, on average there are fewer form B enzyme molecules transcribing each gene in the starved animal.
Investigation on dispersive properties of photonic crystals for employment of Z-scan method (2007)

We calculate linear and nonlinear optical effective refractive indices of finite period one-dimensional photonic crystals, Bragg reflectors and photonic crystal microcavities, by using numerical dispersion relation. We discuss optical dispersive properties of both the Bragg reflectors and the photonic crystal microcavities. For Bragg reflectors, optical Kerr nonlinearity is enhanced at bandgap edges, and the singularity problem at bandgap edges, occurred in Bloch index for infinite structure, is removed by the numerical dispersion relation. Also, the numerical dispersion relation is adopted to describe optical property of photonic crystal microcavities, for which Bloch index is not available. Optical Kerr nonlinearity in photonic crystal microcavities is found to be more enhanced at optical defect modes than at bandgap edges. Z-scan profiles of a Bragg reflector and a photonic crystal microcavity are numerically simulated based on the calculated nonlinear effective refractive indices, which show peaks at bandgap edges and defect mode incurred by dispersion anomaly.
Occult celiac disease presenting as epilepsy and MRI changes that responded to gluten-free diet (2007)

<h3>Abstract</h3> <h3>Background:</h3> Delays in access to neurologic care is a major problem. In this pilot program, we aimed to evaluate the effectiveness of a novel staffing model for neurology outpatient clinic within an academic neurology center to increase access to neurological care, while incorporating such a model into a growing academic neurology department. <h3>Methods:</h3> We created a new model for provision of access to neurological care that could be introduced in an academic neurological department, the “access clinic”. One attending was assigned to staff the access clinic for one week at a time. This was introduced as rotation equal to conventional on-service inpatient rotations. Descriptive analyses were performed to characterize the access clinic’s performance characteristics. Comparisons were made to the previously established traditional faculty clinic model. <h3>Results:</h3> 5,917 access clinic visits were compared to 6,000 traditional clinic visits. Lead time dropped from 142 to 18 days for new patients, and from 64 to 0 days for return visits. While total readmission rates were similar during both clinic periods, readmission through the emergency room was less for access clinic patients. Access clinic resulted in significant improvement in patient satisfaction ratings. The access clinic model was financially profitable. <h3>Conclusions:</h3> Our findings suggest that introducing an access clinic as service rotation for neurology faculty is both effective in offering enhanced access for patients to neurological care and for patient satisfaction. Future studies may test this model in other centers, and should address effect on provider satisfaction.
Zero-dimensional Model and Pressure Data Analysis of a Variable-Displacement Lubricating Vane Pump (2009)

<div class="htmlview paragraph">A zero-dimensional dynamic model was developed in the Matlab/Simulink® environment to predict the behaviour of a variable-displacement lubricating vane pump for internal combustion engine applications. Based on the geometric and kinematic characteristics of the pump, the model allows predictions of the pressure evolution in each chamber of the pump and in the delivery piping, by employing an integrative-derivative approach. Simulation results were compared with experimental data of pressure transducers, which were fitted along the periphery of the pump case and in the delivery channel. The analysis of the experimental data shows that the pressure dynamics, which is experienced by the transducers, is in some cases quite different from the pressure dynamics in the pump chambers and produces pressure peaks which are not actually present in the original signal. The pressure transducers output was then also modelled in order to properly compare simulation results and experimental data.</div>
Understanding dissociations in dyscalculia (2000)

Neuropsychological studies have revealed different subtypes of dyscalculia, including dissociations between exact calculation and approximation abilities, and an impact of number size on performance. To understand the origins of these effects, we measured cerebral activity with functional MRI at 3 Tesla and event-related potentials while healthy volunteers performed exact and approximate calculation tasks with small and large numbers. Bilateral intraparietal, precentral, dorsolateral and superior prefrontal regions showed greater activation during approximation, while the left inferior prefrontal cortex and the bilateral angular regions were more activated during exact calculation. Increasing number size during exact calculation led to increased activation in the same bilateral intraparietal regions as during approximation, as well the left inferior and superior frontal gyri. Event-related potentials gave access to the temporal dynamics of calculation processes, showing that effects of task and of number size could be found as early as 200-300 ms following problem presentation. Altogether, the results reveal two cerebral networks for number processing. Rote arithmetic operations with small numbers have a greater reliance on left-lateralized regions, presumably encoding numbers in verbal format. Approximation and exact calculation with large numbers, however, put heavier emphasis on the left and right parietal cortices, which may encode numbers in a non-verbal quantity format. Subtypes of dyscalculia can be explained by lesions disproportionately affecting only one of these networks.
Molecular characterization of two Alfalfa Mosaic Virus isolates infecting potato crop in central region of Saudi Arabia. (2014)

During the autumn growing season 2012, thirty-two leaf samples of potato (Solanum tuberosum, L. cv. Herms) plants showing mottling symptoms suspected to be due to viral infection were collected from Hail and Wadi aldawasser regions in Saudi Arabia. These leaf samples were tested serologically using DAS ELISA against Alfalfa Mosaic Virus (AMV). Twenty-three out of the thirty-two samples were positive for AMV. To determine host range, plant sap was extracted from two diseased potato samples representing the two regions and different healthy plants were mechanically inoculated. The disease symptoms induced by the two selected isolates were divided into three groups: systemic and calico symptoms, local chlorotic lesions, and non-symptomatic ones. Total RNA was extracted from different plants showing positive reaction to AMV. RT-PCR was performed using AMV coat protein specific primers. Approximately 700-bp RT-PCR products were amplified, and these PCR products were sequenced in both directions. Nucleotide sequencing analysis showed that these two Saudi Arabian AMV isolates [AMV-PSA-Ha (for the Hail isolate) and AMV-PSA-Wd (for the Wadi Al Dawasser isolate] had a 96.5% identity. Sequence comparison showed that these two isolates of AMV shared 93.2% to 99.7% sequence similarity with the twentyeight reported isolates of AMV obtained from GenBank. The cDNA probe was prepared and hybridized with RNA extraction from symptomatic potato plants. No hybridization was shown with RNA extracts from asymptomatic plants. This is the first report on the genetic variability of AMV isolates infecting potato crop in Saudi Arabia. © 2014 Friends Science Publishers
A Cloud-Based Platform for Watching Same Content on Three-Screen TV Continuously in Smart Home (2013)

Watching Same Content on Three-Screen TV Continuously (WSC3STVC) has been considered as one of the representative services in smart homes recently. This service offers content mobility among multiple kinds of screens based on user position in home. Quality of Experience (QoE) and service implementation cost are two important challenges for supporting WSC3STVC service. To the best of our knowledge, there is no visible attempt to design a comprehensive platform for supporting this service in smart homes. Benefiting from cloud computing, peer-to-peer (P2P) network, clustering and H.264 SVC transcoding, this paper proposes a QoE-aware and cost-effective platform for supporting WSC3STVC service in smart home. The strong points of the proposed platform are transcoding in cloud instead of Home GateWay (HGW) for decreasing HGW cost, content switching inside HGW for reducing service delay, using a cloud-managed P2P network for improving bandwidth between cloud and homes and also clustering homes for reducing transfer delay between homes.
Hydrophosphination of Propargylic Alcohols and Amines with Phosphine Boranes (2013)

The first uncatalyzed hydrophosphinations of propargylic amines and alcohols with phosphine- borane complexes are described. The reactions proceed at ambient temperature or below without the use of protecting groups or the need to handle pyrophoric secondary phosphines, furnishing air-stable phosphineborane-amines and alcohols in good yields. Utilization of chiral propargylic substrates and unsymmetrical secondary phosphineboranes leads to diastereomeric P-chiral products that can be separated by fractional crystallization or chromatography. Initial applications of these new P-X species to asymmetric catalysis are detailed.
