Search for resonant pair production of Higgs bosons in the bb¯bb¯ final state using pp collisions at s=13  TeV with the ATLAS detector (2022)

A search for resonant Higgs boson pair production in the $b\overline{b}b\overline{b}$ final state is presented. The analysis uses $126\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}--139\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $pp$ collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond to resonant $HH$ production via gluon-gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross section times branching ratio to Higgs boson pairs of a new resonance in the mass range from $251\text{ }\text{ }\mathrm{GeV}$ to $5\text{ }\text{ }\mathrm{TeV}$.
Multiple Determinants for Rapid Agonist-Induced Internalization of a Nonmammalian Gonadotropin-Releasing Hormone Receptor: A Putative Palmitoylation Site and Threonine Doublet within the Carboxyl-Terminal Tail Are Critical (2003)

The chicken GnRH receptor (cGnRH-R) differs from all mammalian GnRH-Rs in possessing a cytoplasmic carboxyl-terminal tail. We have previously demonstrated that the cGnRH-R undergoes more rapid agonist-induced internalization than the mammalian GnRH-Rs and requires the carboxyl-terminal tail for this process. To investigate the structural determinants mediating this rapid internalization, a series of mutant receptors was generated, including progressive truncations of the tail and substitution of serine and threonine residues with alanine. Truncation of the carboxyl-terminal tail to position 366 and then to position 356 resulted in a progressive attenuation of the rate and total extent of receptor internalization. However, truncation between positions 356 and 346 did not alter the kinetics of internalization further, whereas a further truncation to position 337 resulted in an additional marked reduction of internalization. We show that the membrane-proximal Cys(328) and the Thr(369)Thr(370) doublet located in the distal carboxyl terminus play a critical role in mediating rapid internalization. We demonstrate that the cGnRH-R, when expressed in both COS-7 and HEK 293 cells, preferentially undergoes rapid agonist-induced internalization in a caveolae-like, dynamin-dependent manner. These conclusions are based on our observation that pretreatments with filipin and methyl-beta-cyclodextrin, agents that disrupt lipid rafts such as caveolae, and coexpression of dominant-negative dynamin-1 (K44A) and caveolin-1 (Delta 1-81) mutants, effectively inhibited rapid agonist-induced internalization. Furthermore, cGnRH-Rs appeared to be mobilized to the beta-arrestin- and clathrin-coated, vesicle-mediated endocytic pathway upon beta-arrestin overexpression.
Improved Vibration Isolating Seat Suspension Designs Based on Position-Dependent Nonlinear Stiffness and Damping Characteristics (2003)

The design of seat suspensions having linear stiffness and damping characteristics involves a tradeoff between three performance measures. These measures are: (1) suspension range of motion, (2) improved average vibration isolation (weighted average across a wide exposure spectrum), and (3) improved isolation at the frequency of peak transmissibility. To overcome the limitations associated with this tradeoff, nonlinear mechanical properties are used here in the design of a seat suspension. From the infinite number of possible nonlinear mechanical characteristics, several possibilities that showed promise in previous studies were selected. The selected nonlinear force-deflection relationship (stiffness) of the seat is described by a combination of cubic and linear terms. The selected damping behavior of the seat is described by a combination of a linear term and a position-dependent term. A lumped parameter model (linear-human/nonlinear-seat) of the human/seat-suspension coupled system and a robust direct search routine are used to obtain pseudo-optimal values of the seat design parameters (mass, stiffness, and damping) via simulation in the time domain. Results indicate that the optimal nonlinear seat suspension is significantly better than the optimal linear seat suspension in overall vibration isolation characteristics.
Near-edge X-ray absorption fine-structure spectroscopy of naphthalene diimide-thiophene co-polymers (2014)

Near-edge X-ray absorption fine-structure (NEXAFS) spectroscopy is an important tool for probing the structure of conjugated polymer films used in organic electronic devices. High-performance conjugated polymers are often donor-acceptor co-polymers which feature a repeat unit with multiple functional groups. To facilitate better application of NEXAFS spectroscopy to the study of such materials, improved understanding of the observed NEXAFS spectral features is required. In order to examine how the NEXAFS spectrum of a donor-acceptor co-polymer relates to the properties of the sub-units, a series of naphthalene diimide-thiophene-based co-polymers have been studied where the nature and length of the donor co-monomer has been systematically varied. The spectra of these materials are compared with that of a thiophene homopolymer and naphthalene diimide monomer enabling peak assignment and the influence of inter-unit electronic coupling to be assessed. We find that while it is possible to attribute peaks within the π* manifold as arising primarily due to the naphthalene diimide or thiophene sub-units, very similar dichroism of these peaks is observed indicating that it may not be possible to separately probe the molecular orientation of the separate sub-units with carbon K-edge NEXAFS spectroscopy.
Data from Loss of Androgen Receptor Expression Promotes a Stem-like Cell Phenotype in Prostate Cancer through STAT3 Signaling (2023)

&lt;div&gt;Abstract&lt;p&gt;Androgen receptor (AR) signaling is important for prostate cancer progression. However, androgen-deprivation and/or AR targeting-based therapies often lead to resistance. Here, we demonstrate that loss of AR expression results in STAT3 activation in prostate cancer cells. AR downregulation further leads to development of prostate cancer stem-like cells (CSC), which requires STAT3. In human prostate tumor tissues, elevated cancer stem-like cell markers coincide with those cells exhibiting high STAT3 activity and low AR expression. AR downregulation-induced STAT3 activation is mediated through increased interleukin (IL)-6 expression. Treating mice with soluble IL-6 receptor fusion protein or silencing STAT3 in tumor cells significantly reduced prostate tumor growth and CSCs. Together, these findings indicate an opposing role of AR and STAT3 in prostate CSC development. &lt;i&gt;Cancer Res; 74(4); 1227–37. ©2013 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
NeuRon/spl trade/ netform: a self-organizing wireless sensor network (2003)

This paper introduces the neuRFon/spl trade/ Netform, a self-organizing wireless network for low data rate, low-power fixed sensor nodes. The protocol utilizes a logical backbone architecture through which data communications between all the network nodes are supported by hierarchical routing. We present algorithms that underpin the self-organizing features. The first algorithm constructs the optimal backbone as new nodes are introduced. The second algorithm dictates how the nodes exchange essential information for maintaining the optimal routing backbone as the network evolves. The third algorithm enables the network to recover automatically from node/link failures. The neuRFon/spl trade/ Netform is designed to work in conjunction with a low duty cycle MAC protocol, described in this paper, in order to support long battery life for wireless sensors. To illustrate the performance of the neuRFon/spl trade/ system, we present simulation results showing network formation time, data packet delivery response time, and communication duty cycles of sensor nodes for a neuRFon/sup TM/ system with 64 nodes.
Third Asia-Pacific consensus recommendations on colorectal cancer screening and postpolypectomy surveillance (2022)

The Asia-Pacific region has the largest number of cases of colorectal cancer (CRC) and one of the highest levels of mortality due to this condition in the world. Since the publishing of two consensus recommendations in 2008 and 2015, significant advancements have been made in our knowledge of epidemiology, pathology and the natural history of the adenoma-carcinoma progression. Based on the most updated epidemiological and clinical studies in this region, considering literature from international studies, and adopting the modified Delphi process, the Asia-Pacific Working Group on Colorectal Cancer Screening has updated and revised their recommendations on (1) screening methods and preferred strategies; (2) age for starting and terminating screening for CRC; (3) screening for individuals with a family history of CRC or advanced adenoma; (4) surveillance for those with adenomas; (5) screening and surveillance for sessile serrated lesions and (6) quality assurance of screening programmes. Thirteen countries/regions in the Asia-Pacific region were represented in this exercise. International advisors from North America and Europe were invited to participate.
Growth and Spawning Characteristics of Southern Riverine and Northern Strain Walleyes in Texas (1995)

Genetically-marked strains of walleye (Stizostedion vitreum vitreuni) from Arkansas (ARS) and Iowa (IAS) were stocked simultaneously into a Texas reservoir in 1985 to evaluate strain-related performance differences associated with spawning and growth. Post-stocking collections made during the spring spawning season (1988-1990) resulted in the capture of 132 walleyes from this year class. ARS walleyes comprised 35% of 1985 year-class samples which was significantly higher than the stocking proportion (26%). Differences were attributed to ARS females being more abundant than IAS females in samples. This unexpectedly high abundance of ARS walleye was not considered an indication of higher survival but merely evidence of temporal differences in movement of females of each strain to spawning grounds. This hypothesis was supported by strain-relate d sex ratio differences identified in samples; ARS ratios favored females whereas IAS ratios favored males. Survival was deemed similar between strains throughout the dura- tion of the 5-year study. Natural year classes were produced following the intro- ductions, but they could not be specifically traced to ARS walleye spawning. ARS walleyes attained larger sizes than IAS walleyes. ARS females were significantly longer and heavier than IAS females by age 3. ARS males were significantly longer and heavier than IAS males by age 4. Future stockings of ARS walleyes in Texas may provide anglers with larger walleyes than have typically been available with IAS walleye but they do not hold promise for increasing natural reproduction.

The compatibility of the different PET is also evaluated for C045 dual damascene level using trench first MHM integration.
Recursive feature elimination for biomarker discovery in resting-state functional connectivity (2016)

Biomarker discovery involves finding correlations between features and clinical symptoms to aid clinical decision. This task is especially difficult in resting state functional magnetic resonance imaging (rs-fMRI) data due to low SNR, high-dimensionality of images, inter-subject and intra-subject variability and small numbers of subjects compared to the number of derived features. Traditional univariate analysis suffers from the problem of multiple comparisons. Here, we adopt an alternative data-driven method for identifying population differences in functional connectivity. We propose a machine-learning approach to down-select functional connectivity features associated with symptom severity in mild traumatic brain injury (mTBI). Using this approach, we identified functional regions with altered connectivity in mTBI. including the executive control, visual and precuneus networks. We compared functional connections at multiple resolutions to determine which scale would be more sensitive to changes related to patient recovery. These modular network-level features can be used as diagnostic tools for predicting disease severity and recovery profiles.
Search for the Theta+ pentaquark in the gamma d -> Lambda n K+ reaction measured with CLAS (2016)

For the first time, the reaction gamma d -&amp;gt; Lambda n K+ has been analyzed in order to search for the exotic pentaquark baryon Theta+(1540). The data were taken at Jefferson Lab, using the Hall-B tagged-photon beam of energy between 0.8 and 3.6 GeV and the CEBAF Large Acceptance Spectrometer (CLAS). No statistically significant structures were observed in the nK+ invariant mass distribution. The upper limit on the gamma d -&amp;gt; Lambda Theta+ integrated cross section has been calculated and found to be between 5 and 25 nb, depending on the production model assumed. The upper limit on the differential cross section is also reported.

Mechanical properties of ABS resin reinforced with recycled CFRP (2007)

This paper presents the mechanical properties of a composite consisting of acrylonitrile-butadiene-styrene (ABS) resin mixed with carbon fiber reinforced plastics (CFRP) pieces (CFRP/ABS). CFRP pieces made by crushing CFRP wastes were utilized in this material. Nine kinds of CFRP/ABS compounds with different weight fraction and size of CFRP pieces were prepared. Firstly, tensile and flexural tests were performed for the specimens with various CFRP content. Next, fracture surfaces of the specimens were microscopically observed to investigate fracture behavior and fiber/resin interface. Finally, the tensile modulus and strength were discussed based on the macromechanical model. It is found that the elastic modulus increases linearly with increasing CFRP content while the strength changes nonlinearly. Microscopic observation revealed that most carbon fibers are separated individually and dispersed homogeneously in ABS resin. Epoxy resin particles originally from CFRP are dispersed in ABS resin and seem to be in good contact with surrounding resin. The modulus and strength can be expressed using a macromechanical model taking account of fiber orientation, length and interfacial bonding in short fiber composites.
Spiky parallel dc electric fields in the aurora (1987)

A series of computer simulations is reported on the detailed shape and distribution of the dc electric fields that result when an external potential drop is applied to a plasma with strong low‐frequency turbulence. The structures are shown to depend on the size of the potential drop and upon the shape of the ion turbulence. For the type of turbulence expected for current driven electrostatic ion cyclotron waves the dc fields seen in the simulations are in good agreement with those observed in the aurora.
On the Trade-Off Between Quality Factor and Tuning Ratio in Tunable High-Frequency Capacitors (2009)

A benchmark of tunable and switchable devices at microwave frequencies is presented on the basis of physical limitations to show their potential for reconfigurable cellular applications. Performance limitations are outlined for each given technology focusing on the quality factor ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</i> ) and tuning ratio (eta) as figures of merit. The state of the art in terms of these figures of merit of several tunable and switchable technologies is visualized and discussed. If the performance of these criteria is not met, the application will not be feasible. The quality factor can typically be traded off for tuning ratio. The benchmark of tunable capacitor technologies shows that transistor-switched capacitors, varactor diodes, and ferroelectric varactors perform well at 2 GHz for tuning ratios below 3, with an advantage for GaAs varactor diodes. Planar microelectromechanical capacitive switches have the potential to outperform all other technologies at tuning ratios higher than 8. Capacitors based on tunable dielectrics have the highest miniaturization potential, whereas semiconductor devices benefit from the existing manufacturing infrastructure.
Electronic transport measurements and Raman spectroscopy on carbon nanotube devices (2009)

Abstract An individual single wall carbon nanotube (SWCNT) device has been fabricated and measured using both low temperature transport and Raman measurements. With these mutually independent methods we can study the correlation between the techniques on semiconducting or metallic behavior of the tube. Furthermore, we study the structure of the nanotube by probing Raman measurements at different spots along the tube axis.
Appropriateness of the Modality of Revascularization According to the SYNTAX Score II 2020 in the FASTTRACK CABG Study: An Interim Report on Patient Selection (2023)

Memory Effect of Self‐Assembled PS‐b‐PEO Block Copolymer Films with Selectively Embedded Functionalized TiO2 Nanoparticles (2017)

The memory effect in organic thin film transistors is described with a dielectric hybrid material composed of selectively localized charge trapping titania nanoparticles in a polystyrene‐ b ‐polyethyleneoxide (PS‐ b ‐PEO) diblock copolymer film. Upon solvent annealing in toluene atmosphere, the films readily form nanophase‐separated features of PEO cylinders in a matrix of PS. X‐ray reflectivity (XRR) investigations reveal that the TiO 2 particles are selectively distributed in the top half of the hybrid layers. Applied in organic thin film transistor devices with 2‐tridecyl‐[1]benzothieno[3,2‐b][1]benzothiophen (mono‐C 13 ‐BTBT) semiconductor, the hybrid layers induce clockwise drain current hysteresis with promising memory ratio, long‐term stability, and endurance. The occurrence of nonvolatile charge trapping directly relates to the hierarchically assembled nanostructure of the nanoparticles in the block copolymer since reference devices with PS homopolymers blended with TiO 2 are found to be hysteresis free. Morphological characterization of the hybrid dielectric layers by atomic force microscopy and XRR experiments is presented to shed light on the internal electron density distribution. The layers are subsequently tested in capacitor stacks and transistors.
