Diffusion through channel derivatives of the Escherichia coli FhuA transport protein (2002)

FhuA is a multifunctional protein in the outer membrane of Escherichia coli that actively transports [Fe3+]ferrichrome, the antibiotics albomycin and rifamycin CGP 4832, and mediates sensitivity of cells to the unrelated phages T5, T1, phi80 and UC-1, and to colicin M and microcin J25. The energy source of active transport is the proton motive force of the cytoplasmic membrane that is required for all FhuA functions except for infection by phage T5. The FhuA crystal structure reveals 22 antiparallel transmembrane beta-strands that form a beta-barrel which is closed by a globular N-terminal domain. FhuA still displays active transport and sensitivity to all ligands except microcin J25 when the globular domain (residues 5-160) is excised and supports weakly unspecific diffusion of substrates across the outer membrane. Here it is shown that isolated FhuADelta5-160 supported diffusion of ions through artificial planar lipid bilayer membranes but did not form stable channels. The double mutant FhuADelta5-160 Delta322-336 lacking in addition to the globular domain most of the large surface loop 4 which partially constricts the channel entrance, displayed an increased single-channel conductance but formed no stable channels. It transported in vivo[Fe3+]ferrichrome with 45% of the rate of wild-type FhuA and did not increase sensitivity of cells to antibiotics. In contrast, a second FhuA double mutant derivative which in addition to the globular domain contained a deletion of residues 335-355 comprising one-third of surface loop 4 and half of the transmembrane beta-strand 8 formed stable channels in lipid bilayers with a large single-channel conductance of 2.5 nS in 1 m KCl. Cells that synthesized FhuADelta5-160 Delta335-355 showed an increased sensitivity to antibiotics and supported diffusion of maltodextrins, SDS and ferrichrome across the outer membrane. FhuADelta5-160 Delta335-355 showed no FhuA specific functions such as active transport of [Fe3+]ferrichrome or sensitivity to the other FhuA ligands. It is concluded that FhuADelta5-160 Delta335-355 assumes a conformation that is incompatible with any of the FhuA functions.
Variable heavy tailed durations in Internet traffic. Part I. Understanding heavy tails (2003)

The paper is part of a larger paper (see Hernandez-Campos, F. et al., http://www.cs.unc.edu/Research/dirt/proj/marron/VarHeavyTails, 2002) that studies the tails of the duration distribution of Internet data flows, and their "heaviness". Data analysis motivates the concepts of moderate, far and extreme tails for understanding the richness of information available in the data. The analysis also motivates a notion of "variable tail index", which leads to a generalization of existing theory for heavy tail durations leading to long range dependence. The emphasis here is on understanding heavy tails.
On Topology Optimization and Routing in Integrated Access and Backhaul\n Networks: A Genetic Algorithm-based Approach (2021)

In this paper, we study the problem of topology optimization and routing in\nintegrated access and backhaul (IAB) networks, as one of the promising\ntechniques for evolving 5G networks. We study the problem from different\nperspectives. We develop efficient genetic algorithm-based schemes for both IAB\nnode placement and non-IAB backhaul link distribution, and evaluate the effect\nof routing on bypassing temporal blockages. Here, concentrating on millimeter\nwave-based communications, we study the service coverage probability, defined\nas the probability of the event that the user equipments' (UEs) minimum rate\nrequirements are satisfied. Moreover, we study the effect of different\nparameters such as the antenna gain, blockage and tree foliage on the system\nperformance. Finally, we summarize the recent Rel-16 as well as the upcoming\nRel-17 3GPP discussions on routing in IAB networks, and discuss the main\nchallenges for enabling mesh-based IAB networks. As we show, with a proper\nnetwork topology, IAB is an attractive approach to enable the network\ndensification required by 5G and beyond.\n
Preliminary Study of Trace-Cache-Based Control Independence Architecture. (2006)

Conventional superscalar processors recover from a mispredicted branch by squashing all instructions after the branch. While simple, this approach needlessly re-executes many future control-independent (CI) instructions after the branch's reconvergent point. Selective recovery is possible, but is complicated by the fact that some control-independent instructions must be singled out for re-execution, namely those that depend on data influenced by the mispredicted branch. That is, control-independent data-dependent (CIDD) instructions must be singled out for re-execution, thus avoiding needless re-execution of control-independent data-independent (CIDI) instructions.\n\nTo contrast different recovery models, we abstract the recovery process as constructing a "recovery sub-program" for repairing partially incorrect future state. In this conceptual framework, selective recovery constructs a shorter recovery sub-program than full recovery. In current selective recovery microarchitectures, the recovery sub-program is constructed on-the-fly after detecting a mispredicted branch, by sequencing through all CI instructions and singling out only the CIDD instructions among them. Not only is this discriminating approach complex, but the same recovery sub-program is repeatedly constructed every time this branch is mispredicted.\n\nWe propose constructing the recovery sub-program for each branch once and caching it for future use. In particular, traces of CIDD instructions are pre-constructed and stored in a recovery trace cache. When a misprediction is detected, first, the branch's correct control-dependent instructions are fetched from the conventional instruction cache as usual. Then, at the reconvergent point, fetching simply switches from the instruction cache to the recovery trace cache. The appropriate recovery trace is fetched from the recovery trace cache at this time. In this way, fetching only the CIDD instructions is as simple as fetching all CI instructions from a conventional instruction cache. No explicit singling-out process is needed as this was done a priori, on the fill-side of the trace cache. Therefore, the recovery trace cache is efficient on multiple levels, combining the simplicity of full recovery with the performance of selective recovery.\n\nThis thesis explains the proposed trace-cache-based control independence architecture, at a high level. Preliminary studies are also presented, to project the potential of exploiting control independence as well as the effectiveness of a trace-cache-based approach in particular. The results include (i) breakdowns of retired dynamic instructions into different categories, based on their control and data dependences with respect to prior mispredicted branches, (ii) contributions of individual recovery traces to total CIDI instruction savings, and (iii) hit ratios of finite recovery trace caches.
Experiments on Peeling-Off of Reinforcement Layers from Inner Surface of FRP Pipe due to Water Flow (1987)

As the FRP is superior in the corrosin resistance and is more inexpensive in material cost than corrosion resistant metallics, recently it is widely used for large diameter piping material.Tojoin the FRP piping of large diameter, a double lap joint is generally used, in which the secondary adhesion is applied on both inner and outer surface. Until now it is empirically said that the design water velocity is 3m/s and critical water velocity is 6-10m/s with regard to the peeling-off of the second adhesion part laminated inner face produced by water flow. But the piping for sewer and water-conveyance that has been used until now is flat with low water velocity and low water head. The process piping of large diameter is provided with bends, branches, pipes with head, control calves and heaters in the piping system. The pressure, velocity and temperature vary greatly in the pipe. Therefore, it is necessary to consider whether the values on the basis of former experiment are suitable for the process piping. The purpose of this report is to make clear the basis of the peeling-off limit in the former experiences. In this report of part I, the experiment of the peeling-off by the water jet is shown. This experiment is concerned with the forming factor and selection of material, disregarding the secular deterioration of resin. In the next report (Part 2), the same experiment on the secular detrioration of resin will be shown. The mechanism of peeling-off by water flow will also be considered. Further a new method of the second adhesion joint which will prevent the occurence of the peeling-off will be proposed.
Villoglandular Adenocarcinoma of the Uterine Cervix: An Analysis of 12 Clinical Cases (2011)

Background: Villoglandular adenocarcinoma (VGA) of the uterine cervix is a relatively rare subtype of endocervical adenocarcinomas that often occurs in early reproductive women. Methods: Clinical cases were retrospectively collected from the cancer registry systems at Mackay Memorial Hospital (Taipei, Taiwan). Clinical histories on the subjects were extracted directly from chart review of records of clinic visits. Results: The mean age of 12 subjects was 42 years, with 10 and 2 subjects clinically staged as IB1 (10 of 12) and IA2 (2 of 12), respectively, for the period between January 1, 1996, and December 31, 2007. Eleven subjects had classical Type III radical hysterectomy with or without bilateral salpingo-oophorectomy plus bilateral pelvic lymphadenectomy, and one received pelvic and para-aortic lymphadenectomy plus postoperative adjuvant treatment of weekly cisplatin concurrent with radiotherapy. Only one subject had confirmed pelvic lymph nodes metastases. Nine subjects had pure histologic type and others had mixed histologic type of VGA. Only one subject had a recurrence but was still alive. Most subjects were long-term survivors (greater than 5 years) (10 of 12). Conclusion: In conclusion, this study confirms the young age of subjects with VGA and reemphasizes the difficulties in the diagnosis of VGA. Because the current management strategy renders good tumor control in young subjects with early-stage VGA, we would suggest that similar treatment should be considered for elder subjects with this rare category of cervical malignancy. Our experience shows that the primary management of subjects with early-stage VGA (International Federation of Gynecology and Obstetrics Stages IA2 to IIA1) is classical Type III radical hysterectomy plus salpingo-oophorectomy with bilateral pelvic lymphadenectomy at MMH. We hope our 12-case experience may contribute to the clinical decision making for subjects with this disease.
Structure and Regulation of Histone H2B mRNAs from Leishmania enriettii (1991)

We have studied the structure and expression of histone H2B mRNA and genes in the parasitic protozoan Leishmania enrietti. A genomic clone containing three tandemly repeated genes has been sequenced and shown to encode three identical histone proteins and two types of closely related mRNA sequence. We have also sequenced three independent cDNA clones and demonstrated that the Leishmania H2B mRNAs are polyadenylated, similar to the basal histone mRNAs of higher eucaryotes and the histone mRNAs of yeast. In addition, the Leishmania mRNAs contain inverted repeats near the poly(A) tail which could form stem-loops similar in secondary structure, but not in sequence, to the 3' stem-loops of nonpolyadenylated replication-dependent histones of higher eucaryotes. Unlike the replication-dependent histones, the Leishmania histone H2B mRNAs do not decrease in abundance following treatment with inhibitors of DNA synthesis. The histone mRNAs are differentially expressed during the parasite life cycle and accumulate to a higher level in the extracellular promastigotes (the form which in nature lives within the gut of the insect vector) than in the intracellular amastigotes (the form that lives within the mammalian host macrophages).
DNA-mediated self-assembly of polyhedral plasmonic clusters (2015)

A metafluid is a collection of electromagnetic resonators that have an isotropic response to incoming light. Because the resonators need not be oriented in any particular direction, metafluids are perhaps the simplest metamaterial to fabricate – if one can first design resonators with an isotropic response. Such structures can in principle be self-assembled from metallic colloidal particles. The challenge is to organize these 100-nm-scale metallic particles into high-symmetry clusters, such as tetrahedra, that have very little variability between structures, so that the electric and magnetic resonances of all the clusters are at the same frequency. I will discuss how DNA can be used to assemble bulk suspensions of polyhedral colloidal clusters, using both equilibrium and non-equilibrium methods2. I will also discuss how the yield of the structures is related to statistical mechanical and geometrical considerations.
Inside the Michelangelo effect: The role of art and aesthetic attractiveness on perceived fatigue and hand kinematics in virtual painting (2022)

It has recently been discovered that during a virtual reality task of painting, if the subjects have the illusion of recreating an artistic masterpiece, they improve their performances and perceive less fatigue compared to simply coloring a virtual canvas. This phenomenon has been called the Michelangelo effect. However, it was unclear if this effect was related to the aesthetic experience of beauty or if it was specific to artistic stimuli. To clarify this point, 26 healthy subjects performed the virtual task of erasing a blank sheet on the canvas, revealing an image that could be a painting or a photo, classified as beautiful or not. Beautiful paintings were famous artistic portraits, non-beautiful paintings were rough reproductions of them. Photos of popular people were matched with paintings according to their similarity for somatic traits, posture, and clothes. Beautiful and non-beautiful photos were classified according to whether the pictured person was famous or not for their beauty. For each stimulus the objective beauty, subjective beauty, and effort to complete the task perceived by the subject were self-assessed on a numerical rating scale, recorded and analyzed. Furthermore, the hand kinematic trajectory was instrumentally recorded and its spatiotemporal parameters were computed. Less fatigue was perceived for the paintings than for the photos (p = .020), but not for beautiful versus non-beautiful stimuli (p = .325). Only in the artistic stimuli, subjective beauty was found to be negatively correlated with perceived fatigue (p = .030) and performed errors (p = .005). The kinematic parameters were found to be affected by the interactions between the gender of the participant and that of the person in the photo. These results supported the idea that the Michelangelo effect was stronger when subjects interacted with artefacts, modulated by the perceived beauty of the artistic stimulus.
High-performance liquid chromatographic method for the simultaneous detection of the adulteration of cereal flours with melamine and related triazine by-products ammeline, ammelide, and cyanuric acid (2007)

Melamine has been used for the adulteration of cereal flours in order to increase their apparent protein content. Crude melamine may contain several by-products, i.e. ammeline, ammelide, and cyanuric acid. The simultaneous analysis of all four chemicals is difficult because of the formation of an insoluble salt between melamine and cyanuric acid. A simple and convenient high-performance liquid chromatography (HPLC) method for the detection of the adulteration of cereal flours with all four chemicals is proposed herein. The precipitate formation between melamine and cyanuric acid was prevented by using alkaline conditions (pH 11-12) for both standards preparation and sample extraction. The method uses matrix-matching, which involves the construction of a calibration curve on a blank (negative control) matrix, which is then used for the quantitation of melamine and by-products in adulterated (positive) samples. Matrix-matching compensates for analyte losses during sample preparation, and for matrix effects. The method was successfully applied to wheat, corn, and rice flours, and is expected to be applicable (with some modifications) to soy flour as well. The method allows for the detection of melamine, ammeline, and ammelide at approximately 5 microg g(-1), and cyanuric acid at approximately 90 microg g(-1) in wheat flour.
309 Fabrication of porous copper with uniform pore size by friction powder compaction process (2012)

Open-cell porous copper (Cu) was fabricated by friction powder compaction (FPC) process, which requires no external heat sources. In this process, a mixture of Cu powder and sodium chloride (NaCI) powder as spacer particle are used as starting materials. The compacting of the powder mixture are conducted only by rotating tool plunged into the mixture. NaCl is removed by placing the sintered mixture in water, and pores are formed. Porous Cu with porosities of 60-80 pct was successfully fabricated. In this study, a relationship between leaching time and removal of NaCl were investigated, and pore structures of obtained porous Cu were nondestructively observed by X-ray CT. In addition the compressive response of obtained porous Cu was investigated.
Master Device With Bending Safety for Flexible Surgical Robots (2020)

Abstract Flexible robots have been widely studied for application to minimally invasive surgery because of their dexterity and miniaturization ability. Conventional master devices developed to manipulate rigid link-type robots are difficult to apply to flexible robots due to structural difference. In addition, the different kinematic structures of the master device and flexible slave robot cause complex mapping issues. Furthermore, most high-redundancy flexible robots inserted through an over-tube have limited bending angles depending on the insertion depth. Conventional master devices were not designed to comply with this limitation of flexible robots. We developed an isosceles master device that provides intuitive and simple mapping factors for controlling and maintaining the wire tension of a flexible robot in a safe range. We applied a variable isosceles triangle mechanism that structurally limits the bending angle according to the insertion depth. Experimental results showed that our master device can control a flexible slave robot with an error of less than 1.5 mm. Because of the limited bending angle, excessive tension and the resulting damage to the wire were prevented. The isosceles master device can also hold its position and orientation with a passive holding mechanism.

The Drawability Test by the Single Blank Deep Drawing Method (1970)

Drawability of metal sheets is indicated by Swift’s L.D.R., C.C.V. of Fukui’s, and the plastic strain ratio r. Swift’s L.D.R. and C.C.V. of Fukui’s tests are based on the deep drawing test, while the plastic strain ratio r is determined simply by the tensile test. It has been reported by many investigators that these values are excellent indicators of drawability. But it is difficult in practice to indicate the drawability of thin sheets by Fukui’s test and the plastic strain ratio r. On the other hand, Swift’s test is favorable for thin sheets, but in addition to the complexity to determine the L.D.R. of metal sheets, the reproducibility of the value obtained is doubtful.So in this paper the validity of the load deep drawing method was discussed, where the value is indicated by the ratio of fracture load in the cup wall to the maximum load to deform the flange. Although the fracture load must be kept constant irrespective of the drawing ratio, the observed values are at variance, and therefore L.D.R. of metal sheets cannot be determined by this so-called T.Z.P. method. But it has been found that the fracture loads of the cup wall in various drawing ratios can be kept constant by a suitable lubricating operation, thus enabling the load deep drawing method to determine the drawability of thin metal sheets.
The Effect of Polymer Architecture on Solid-liquid Separations with Temperature-responsive Derivatives of Poly(N-Isopropyl Acrylamide) (2010)

The effects of suspension temperature and polymer architecture on the solid-liquid separations of silica suspensions which have been flocculated with derivatives of PNIPAM have been investigated using batch settling tests and polymer adsorption studies. Polymer architecture is shown to strongly influence colloidal stability and different regions of suspension behaviour are identified and classified in terms of polymer charge and charge-sign. Due to significant electrostatic interactions between the silica particles and the charged-PNIPAM copolymers, the settling and consolidation behaviour of sediments was found to be less responsive to changes in temperature than neutral-PNIPAM. Information about the influence of suspension temperature and polymer architecture will assist in the future application of these flocculant systems to larger-scale thickener projects.

Associations Between Pregnancy-Related Predisposing Factors for Offspring Neurodevelopmental Conditions and Parental Genetic Liability to Attention-Deficit/Hyperactivity Disorder, Autism, and Schizophrenia (2022)

In this study, genetic liability to neurodevelopmental conditions that is passed from mothers to children was associated with several pregnancy-related factors and may therefore confound associations between these pregnancy-related factors and offspring neurodevelopment that have previously been thought to be causal. It is crucial that future study designs account for genetic confounding to obtain valid causal inferences so that accurate advice can be given to pregnant individuals.
