Arcee: An OCM-Solver
No full textThe 2024 PACE Challenge focused on the One-Sided Crossing Minimization (OCM) problem, which aims to minimize edge crossings in a bipartite graph with a fixed order in one partition and a free order in the other. We describe our OCM solver submission that utilizes various reduction rules for OCM and, for the heuristic track, employs local search approaches as well as techniques to escape local minima. The exact and parameterized solver uses an ILP formulation and branch & bound to solve an equivalent Feedback Arc Set instance.Long versio

MATLAB codes to calibrate and process BiTe OCM data
No full textSignificance: Full-field optical coherence microscopy (FF-OCM) is a prevalent technique for backscattering and phase imaging with epi-detection. Traditional methods have two limitations: suboptimal utilization of functional information about the sample and complicated optical design with several moving parts for phase contrast.Aim: We report an OCM setup capable of generating dynamic intensity, phase, and pseudo-spectroscopic contrast with single-shot full-field video-rate imaging called bichromatic tetraphasic (BiTe) full-field OCM with no moving parts.Approach: BiTe OCM resourcefully uses the phase-shifting properties of antireflection (AR) coatings outside the rated bandwidths to create four unique phase shifts, which are detected with two emission filters for spectroscopic contrast.Results: BiTe OCM overcomes the disadvantages of previous FF-OCM setup techniques by capturing both the intensity and phase profiles without any artifacts or speckle noise for imaging scattering samples in three-dimensional (3D). BiTe OCM also utilizes the raw data effectively to generate three complementary contrasts: intensity, phase, and color. We demonstrate BiTe OCM to observe cellular dynamics, image live, and moving micro-animals in 3D, capture the spectroscopic hemodynamics of scattering tissues along with dynamic intensity and phase profiles, and image the microstructure of fall foliage with two different colors.Conclusions: BiTe OCM can maximize the information efficiency of FF-OCM while maintaining overall simplicity in design for quantitative, dynamic, and spectroscopic characterization of biological samples.</p
Organizational Change Management (OCM): Preliminary position paper
Full text linkThis paper describes the initial steps in the development of Organizational Change Management (OCM), a new Critical Capability (CC) of the IT Capability Maturity Framework (IT-CMF). OCM consists of a maturity assessment and an accompanying Body of Knowledge to support an organization’s improvement efforts. An initial overview of the literature related to managing organizational change is described, based on a review of 30+ academic and practitioner publications. Core themes are identified and used to define an initial taxonomy for OCM. This initial structure was further refined and developed in collaboration with industry and academic experts to ensure it both reflects and supports contemporary organizational realities and best practices in organizational change management
Oxidative conversion for methane valorization : exploiting OCM
No full textA novel process for the valorization of cheap, unexploited and accessible methane-rich sources through
the Oxidative Conversion of Methane (OCoM) is proposed in this work. The OCoM process combines
Oxidative Coupling of Methane (OCM) and Post-bed Cracking (PBC), aiming at high ethylene yields
and an equimolar CO:C2H4:H2 ratio aiming at further ethylene hydroformylation to C3 oxygenates. A
MnNaW/SiO2 catalyst is evaluated for the OCM reaction at temperatures and total pressures up to 850
°C and 4 bar, respectively, W/FCH4,in in the range of 1 and 16 kg s mol-1
, inlet CH4/O2 molar ratio
between 3 and 5 and inlet CO2 molar fraction up to 20%. The optimal operating conditions to obtain the
highest ethylene selectivity for OCM are 850 °C and 1 bar. At these conditions, the methane conversion
amounts to 30%, and the selectivities for ethylene, ethane, CO and CO2 are 40%, 10%, 25% and 25%,
respectively. A 10-step kinetic model was developed and allowed properly simulating the
experimentally observed trends. The simulations of the OCoM process, i.e., OCM reactor coupled with
the PBC, showed that ethylene selectivity increased from the 40% obtained from the stand-alone OCM
reactor up to 60%, thereby achieving the targeted CO:C2H4:H2 ratio of 1:1:1
Identification of <i>CG3363</i> as <i>ocm</i>.
No full text<p>A. Genomic region near 60C showing predicted genes and five BACs used to rescue <i>ocm</i>. The BACs shown in black failed to rescue <i>ocm</i> mutations, but 117N13 (yellow) rescued viability and fertility of multiple <i>ocm</i> alleles. B. Conceptual translation of <i>ocm</i> reveals a protein with distinct motifs conserved between other Drosophila species (colored boxes) separated by diverged regions (thin line). The hatched box indicates the segment of OCM used to raise antibodies. C. Similar coding regions are found in the genomes of some other insects. The Bombyx alignment is taken from genomic DNA lacking cDNA support, so the exact alignment is uncertain. D. The Cys431 region (red) is also found in chordate Mga. E. Several Daphnia proteins contain Cys431 motifs. A second cys-rich region (orange) is also present in two of the Daphnia proteins.</p
