Clustering for Clarity: Improving Word Sense Disambiguation through Multilevel Analysis
Authors: Dubey Shivkishan 
Published: July 2024

In natural language processing, a critical activity known as word sense disambiguation (WSD) seeks to ascertain the precise meaning of an ambiguous wordin context. Traditional methods for WSD frequently involve supervised learning methods and lexical databases like WordNet. However, these methods fallshort in managing word meaning complexity and capturing fine-grained differences. In this paper, for increasing the precision and granularity of word sensedisambiguation we proposed multilevel clustering method that goes deeper in the nested levels as locate groups of linked context words and categorize themaccording to their word meanings. With this method, we can more effectively manage polysemy and homonymy as well as detect minute differences in meaning. An actual investigation of the SemCor corpus demonstrates the performance score of multilevel clustering in WSD. This proposed method successfullyseparated clusters and groups context terms according to how semantically related they are, producing improved disambiguation outcomes. A more detailedknowledge of word senses and their relationships may be obtained thanks to the clustering process, which makes it possible to identify smaller clusters inside larger clusters. The outcomes demonstrate how multilevel clustering may enhance the granularity and accuracy of WSD. Our solution overcomes the drawbacks of conventional approaches and provides a more fine-grained representation of word senses by combining clustering algorithms.

A History of International Engagement in the Council for Exceptional Children Since 1980. Part 2: Functions of a Professional Organization
Authors: Keller Clayton , Martin Suzanne 
Published: July 2024

Abstract
Using the results of an integrative literature review of primary sources of the Council for Exceptional Children (CEC)—news articles, reports of initiatives and workgroups, and columns in CEC publications that provided evidence of the Council’s international efforts—we describe instances of international engagement within five functions of the Council as a professional organization for exceptional education: advocacy, professional development, conferences, the translation of CEC content, and its recognition as a leading organization in the field. We believe the efforts can be categorized as serving either one or both simple though challenging goals: bringing the world to CEC and the Division of International Special Education and Services (DISES) and bringing CEC and DISES to the world. Progress has occurred on these goals, albeit sporadically and intermittently. As this history looks to the past, it points to the future. The instances of international engagement that once were provide examples of what can be again to pursue these goals.
Superhydrophobic Surfaces by Electrochemical Processes
Authors: Darmanin Thierry , de Givenchy Elisabeth Taffin , Amigoni Sonia , Guittard Frederic 
Published: February 2013

AbstractThis review is an exhaustive representation of the electrochemical processes reported in the literature to produce superhydrophobic surfaces. Due to the intensive demand in the elaboration of superhydrophobic materials using low‐cost, reproducible and fast methods, the use of strategies based on electrochemical processes have exponentially grown these last five years. These strategies are separated in two parts: the oxidation processes, such as oxidation of metals in solution, the anodization of metals or the electrodeposition of conducting polymers, and the reduction processed such as the electrodeposition of metals or the galvanic deposition. One of the main advantages of the electrochemical processes is the relative easiness to produce various surface morphologies and a precise control of the structures at a micro‐ or a nanoscale.
Oxygen‐Assisted Hydroxymatairesinol Dehydrogenation: A Selective Secondary‐Alcohol Oxidation over a Gold Catalyst

Published: February 2013

AbstractSelective dehydrogenation of the biomass‐derived lignan hydroxymatairesinol (HMR) to oxomatairesinol (oxoMAT) was studied over an Au/Al2O3 catalyst. The reaction was carried out in a semi‐batch glass reactor at 343 K under two different gas atmospheres, namely produced through synthetic air or nitrogen. The studied reaction is, in fact, an example of secondary‐alcohol oxidation over an Au catalyst. Thus, the investigated reaction mechanism of HMR oxidative dehydrogenation is useful for the fundamental understanding of other secondary‐alcohol dehydrogenation over Au surfaces. To investigate the elementary catalytic steps ruling both oxygen‐free‐ and oxygen‐assisted dehydrogenation of HMR to oxoMAT, the reactions were mimicked in a vacuum over an Au28 cluster. Adsorption of the involved molecular species—O2, three different HMR diastereomers (namely, one SRR and two RRR forms), and the oxoMAT derivative—were also studied at the DFT level. In particular, the energetic and structural differences between SRR‐HMR and RRR‐HMR diastereomers on the Au28 cluster were analyzed, following different reaction pathways for the HMR dehydrogenation that occur in presence or absence of oxygen. The corresponding mechanisms explain the higher rates of the experimentally observed oxygen‐assisted reaction, mostly depending on the involved HMR diastereomer surface conformations. The role of the support was also elucidated, considering a very simple Au28 charged model that explains the experimentally observed high reactivity of the Au/Al2O3 catalyst.

AbstractGlycogen is the main source of glucose for many biological events. However, this molecule may have other functions, including those that have deleterious effects on cells. The rate‐limiting enzyme in glycogen synthesis is glycogen synthase (GS). It is encoded by two genes, GYS1, expressed in muscle (muscle glycogen synthase, MGS) and other tissues, and GYS2, primarily expressed in liver (liver glycogen synthase, LGS). Expression of GS and its activity have been widely studied in many tissues. To date, it is not clear which GS isoform is responsible for glycogen synthesis and the role of glycogen in testis. Using RT‐PCR, Western blot and immunofluorescence, we have detected expression of MGS but not LGS in mice testis during development. We have also evaluated GS activity and glycogen storage at different days after birth and we show that both GS activity and levels of glycogen are higher during the first days of development. Using RT‐PCR, we have also shown that malin and laforin are expressed in testis, key enzymes for regulation of GS activity. These proteins form an active complex that regulates MGS by poly‐ubiquitination in both Sertoli cell and male germ cell lines. In addition, PTG overexpression in male germ cell line triggered apoptosis by caspase3 activation, proposing a proapoptotic role of glycogen in testis. These findings suggest that GS activity and glycogen synthesis in testis could be regulated and a disruption of this process may be responsible for the apoptosis and degeneration of seminiferous tubules and possible cause of infertility.

AbstractAntioxidants may prevent apoptosis of cancer cells via inhibiting reactive oxygen species (ROS). However, to date no study has been carried out to elucidate the effects of strong antioxidant N‐acetylcysteine (NAC) on Bleomycin induced apoptosis in human testicular cancer (NTERA‐2, NT2) cells. For this reason, we studied the effects of Bleomycin and NAC alone and in combination on apoptotic signaling pathways in NT2 cell line. We determined the cytotoxic effect of bleomycin on NT2 cells and measured apoptosis markers such as Caspase‐3, ‐8, ‐9 activities and Bcl‐2, Bax, Cyt‐c, Annexin V‐FTIC and PI levels in NT2 cells incubated with different agents for 24 h. Early apoptosis was determined using FACS assay. We found half of the lethal dose (LD50) of Bleomycin on NT2 cell viability as 400, 100, and 20 µg/ml after incubations for 24, 48, and 72 h, respectively. Incubation with bleomycin (LD50) and H2O2 for 24 h increased Caspase‐3, ‐8, ‐9 activities, Cyt‐c and Bax levels and decreased Bcl‐2 levels. The concurrent incubation of NT2 cells with bleomycin/H2O2 and NAC (5 mM) for 24 h abolished bleomycin/H2O2‐dependent increases in Caspase‐3, ‐8, ‐9 activities, Bax and Cyt‐c levels and bleomycin/H2O2‐dependent decrease in Bcl‐2 level. Our results indicate that bleomycin/H2O2 induce apoptosis in NT2 cells by activating mitochondrial pathway of apoptosis, while NAC diminishes bleomycin/H2O2 induced apoptosis. We conclude that NAC has antagonistic effects on Bleomycin‐induced apoptosis in NT2 cells and causes resistance to apoptosis which is not a desired effect in eliminating cancer cells. J. Cell.

Could an anisotropic molecular mechanics/dynamics potential account for sigma hole effects in the complexes of halogenated compounds?
Authors: Hage Krystel El , Piquemal Jean‐Philip , Hobaika Zeina , Maroun Richard G. , Gresh Nohad 
Published: February 2013

AbstractHalogenated compounds are gaining an increasing importance in medicinal chemistry and materials science. Ab initio quantum chemistry (QC) has unraveled the existence of a “sigma hole” along the CX (X = F, Cl, Br, I) bond, namely, a depletion of electronic density prolonging the bond, concomitant with a build‐up on its sides, both of which are enhanced along the F < Cl < Br < I series. We have evaluated whether these features were intrinsically built‐in in an anisotropic, polarizable molecular mechanics (APMM) procedure such as SIBFA (sum of interactions between fragments ab initio computed). For that purpose, we have computed the interaction energies of fluoro‐, chloro‐, and bromobenzene with two probes: a divalent cation, Mg(II), and water approaching X through either one H or its O atom. This was done by parallel QC energy‐decomposition analyses (EDA) and SIBFA computations. With both probes, the leading QC contribution responsible for the existence of the sigma hole is the Coulomb contribution Ec. For all three halogenated compounds, and with both probes, the in‐ and out‐of‐plane angular features of Ec were closely mirrored by the SIBFA electrostatic multipolar contribution (EMTP). Resorting to such a contribution thus dispenses with empirically‐fitted “extra”, off‐centered partial atomic charges as in classical molecular mechanics/dynamics. © 2013 Wiley Periodicals, Inc.
Numerical and experimental analyses of planar asymmetric split‐and‐recombine micromixer with dislocation sub‐channels
Authors: Li Jian , Xia Guodong , Li Yifan 
Published: February 2013

AbstractBACKGROUNDA passive planar micromixer with dislocation sub‐channels, based on the principle of planar asymmetric split and recombination, has been proposed for its effective mixing. Both numerical simulations and experiments were used to design and investigate the effect of parameters and flowing feature on mixing with Reynolds numbers ranging from 1 to 100. The mixing index, which is used as the measurement criteria, is dependent upon Reynolds number and geometrical parameters.RESULTSThrough the results of numerical and experimental simulation, it is evident that the arrangement of dislocation sub‐channel structure will result in better fluid mixing owing to the combination of the unbalanced inertial collisions, the multidirectional vortices and the collision‐induced flow in mixing cavities between every two‐looped structure. The effect of transverse Dean Vortices in the vertical plane and expansion vortices in the horizontal plane is beneficial for the increased interfacial area between two species and promoting mixing. The increased width ratio, w3/w4, provided by the dislocation structures, results in better mixing performance, but also causes a higher pressure drop. Experimental results allow better validation of the mixing efficiency of this micromixer.CONCLUSIONThe best mixing performance was achieved with width ratio of the dislocation sub‐channels at w3/w4 = 1.0 and Reynolds numbers less than 80. To consider the mixing effect and the packaging requirements of the experiment, the mixing index of the micromixer with a dislocation sub‐channel can reach 86%. © 2013 Society of Chemical Industry
Stake Management in Men's Online Cosmetics Testimonials
Authors: Hall Matthew , Gough Brendan , Seymour‐Smith Sarah 
Published: February 2013

ABSTRACTAlthough the Internet has opened up new avenues for identity expression, many web‐based sources have yet to be examined. Online testimonials as a form word‐of‐mouth advertising are a relatively new development. The present study examines the construction of masculinities in men's cosmetics adverting testimonials presented on the website of a leading brand. The dataset is examined using discursive psychology and membership categorization analysis methodologies. The findings indicate that when men write facial cosmetics testimonials they still justify the use of these non‐typical masculine products even in the absence of others’ responses. The analysis highlights the continued difficulty men report in using typically feminized products, frequently accounting for their cosmetic use as a "corrective" measure rather than for beautification. The implications for the marketing of masculine products are discussed.
Development and plasticity of the Drosophila larval neuromuscular junction
Authors: Menon Kaushiki P. , Carrillo Robert A. , Zinn Kai 
Published: February 2013

AbstractThe Drosophila larval neuromuscular system is relatively simple, containing only 32 motor neurons in each abdominal hemisegment, and its neuromuscular junctions (NMJs) have been studied extensively. NMJ synapses exhibit developmental and functional plasticity while displaying stereotyped connectivity. Drosophila Type I NMJ synapses are glutamatergic, while the vertebrate NMJ uses acetylcholine as its primary neurotransmitter. The larval NMJ synapses use ionotropic glutamate receptors (GluRs) that are homologous to AMPA‐type GluRs in the mammalian brain, and they have postsynaptic scaffolds that resemble those found in mammalian postsynaptic densities. These features make the Drosophila neuromuscular system an excellent genetic model for the study of excitatory synapses in the mammalian central nervous system. The first section of the review presents an overview of NMJ development. The second section describes genes that regulate NMJ development, including: (1) genes that positively and negatively regulate growth of the NMJ, (2) genes required for maintenance of NMJ bouton structure, (3) genes that modulate neuronal activity and alter NMJ growth, (4) genes involved in transsynaptic signaling at the NMJ. The third section describes genes that regulate acute plasticity, focusing on translational regulatory mechanisms. As this review is intended for a developmental biology audience, it does not cover NMJ electrophysiology in detail, and does not review genes for which mutations produce only electrophysiological but no structural phenotypes.

Evidence for grow-through penetration of 0.2-μm-pore-size filters by Serratia marcescens and Brevundimonas diminuta
Authors: Kaushal Simran , Gervais Brandi , Lute Scott , Eroraha Ajiri , Faustino Patrick , Brorson Kurt , Hussong David 
Published: February 2013

Abstract
We find that both Brevundimonas diminuta and Serratia marcescens can grow through sterilizing grade filter membranes of different membrane polymer compositions. Although this passage does not occur on a consistent basis, generation of “grow-through positive” results indicate that grow-through can occur stochastically at basal levels. This observation argues that the following risk mitigation strategies during pharmaceutical aseptic processing are warranted: minimization of processing times, and monitoring, minimizing and characterizing pre–filter bioburden.

AbstractMucopolysaccharidosis IVA (MPS IVA), also known as Morquio‐Brailsford or Morquio A syndrome, is a lysosomal storage disorder caused by a deficiency of the enzyme N‐acetyl‐galactosamine‐6‐sulphate sulphatase (GALNS). MPS IVA is multisystemic but manifests primarily as a progressive skeletal dysplasia. Spinal involvement is a major cause of morbidity and mortality in MPS IVA. Early diagnosis and timely treatment of problems involving the spine are critical in preventing or arresting neurological deterioration and loss of function. This review details the spinal manifestations of MPS IVA and describes the tools used to diagnose and monitor spinal involvement. The relative utility of radiography, computed tomography (CT) and magnetic resonance imaging (MRI) for the evaluation of cervical spine instability, stenosis, and cord compression is discussed. Surgical interventions, anaesthetic considerations, and the use of neurophysiological monitoring during procedures performed under general anaesthesia are reviewed. Recommendations for regular radiological imaging and neurologic assessments are presented, and the need for a more standardized approach for evaluating and managing spinal involvement in MPS IVA is addressed.
