Broad Histogram Monte Carlo (1997)

Abstract: We propose a new Monte Carlo technique in which the degeneracy of energy states is obtained with a Markovian process analogous to that of Metropolis used currently in canonical simulations. The obtained histograms are much broader than those of the canonical histogram technique studied by Ferrenberg and Swendsen. Thus we can reliably reconstruct thermodynamic functions over a much larger temperature scale also away from the critical point. We show for the two-dimensional Ising model how our new method reproduces exact results more accurately and using less computer time than the conventional histogram method. We also show data in three dimensions for the Ising ferromagnet and the Edwards Anderson spin glass. In the simulation of thermal systems one typically needs to calculate a variable &amp;lt; Q&amp;gt;T as a function of temperature T. Usually one would have to perform independent Monte Carlo simulations at different values of temperature. An appealing strategy to avoid such multiple simulations is the canonical histogram method [1,2]: The histogram PT(E) of the energies at one given temperature T0 is measured and then the distribution at a different temperature T is obtained by reweighting, i.e. by multiplying with exp(E/T − E/T0) and normalizing. In order to obtain the average &amp;lt; Q&amp;gt;T, one needs to accumulate also the histogram of Q as a function of energy E. The thermal average at temperature T is then &amp;lt; Q&amp;gt;T = ∑
3-D Interpolation in Object Perception: Evidence From an Objective Performance Paradigm. (2005)

Object perception requires interpolation processes that connect visible regions despite spatial gaps. Some research has suggested that interpolation may be a 3-D process, but objective performance data and evidence about the conditions leading to interpolation are needed. The authors developed an objective performance paradigm for testing 3-D interpolation and tested a new theory of 3-D contour interpolation, termed 3-D relatability. The theory indicates for a given edge which orientations and positions of other edges in space may be connected to it by interpolation. Results of 5 experiments showed that processing of orientation relations in 3-D relatable displays was superior to processing in 3-D nonrelatable displays and that these effects depended on object formation. 3-D interpolation and 3-D relatabilty are discussed in terms of their implications for computational and neural models of object perception, which have typically been based on 2-D-orientation-sensitive units.
Production of β-Defensin Antimicrobial Peptides by Maxillary Sinus Mucosa (2001)

beta-Defensins are endogenous cationic peptides with broad-spectrum antimicrobial activity that are thought to play a role in the innate immune response. Two human beta-defensins, beta-defensin-1 (HBD-1) and beta-defensin-2 (HBD-2), have been identified. These peptides have recently been characterized in several human tissues. The presence of these peptides in the paranasal sinuses has not been investigated. We examined maxillaary sinus secretions from six patients with sinusitis and 10 patients without signs, symptoms, or radiologic evidence of sinus disease for the presence of beta-defensins. Cationic peptides were extracted from antral lavage specimens and examined for the presence of HBD-1 and HBD-2 by Western blot. Normal maxillary sinus epithelium was obtained from two patients and analyzed by RT-PCR for the presence of HBD-1 and HBD-2 mRNA. Tissue immunostaining for the two peptides was also used. Western blot analysis identified HBD-1 in two of 10 patients in the control group and in three of six patients in the sinusitis group. HBD-2 was identified in one of 10 patients in the control group and in four of six patients in the sinusitis group. RT-PCR revealed HBD-1 mRNA in one of two normal controls tested. Immunostaining localized HBD-1 and HBD-2 to the epithelial cell cytoplasm. This is the first demonstration of HBD-1 and HBD-2 production in the paranasal sinuses. In the present study, HBD-1 and HBD-2 were detected more frequently in the maxillary sinus fluid of patients with inflamed sinuses than in normal controls.
Completing Circular Bacterial Genomes With Assembly Complexity by Using a Sampling Strategy From a Single MinION Run With Barcoding (2019)

The Oxford Nanopore MinION is an affordable and portable DNA sequencer that can produce very long reads (tens of kilobase pairs), which enable <i>de novo</i> bacterial genome assembly. Although many algorithms and tools have been developed for base calling, read mapping, <i>de novo</i> assembly, and polishing, an automated pipeline is not available for one-stop analysis for circular bacterial genome reconstruction. In this paper, we present the pipeline CCBGpipe for completing circular bacterial genomes. Raw current signals are demultiplexed and base called to generate sequencing data. Sequencing reads are <i>de novo</i> assembled several times by using a sampling strategy to produce circular contigs that have a sequence in common between their start and end. The circular contigs are polished by using raw signals and sequencing reads; then, duplicated sequences are removed to form a linear representation of circular sequences. The circularized contigs are finally rearranged to start at the start position of <i>dnaA</i>/<i>repA</i> or a replication origin based on the GC skew. CCBGpipe implemented in Python is available at https://github.com/jade-nhri/CCBGpipe. Using sequencing data produced from a single MinION run, we obtained 48 circular sequences, comprising 12 chromosomes and 36 plasmids of 12 bacteria, including <i>Acinetobacter nosocomialis</i>, <i>Acinetobacter pittii</i>, and <i>Staphylococcus aureus</i>. With adequate quantities of sequencing reads (80×), CCBGpipe can provide a complete and automated assembly of circular bacterial genomes.
Soft Constraint Logic Programming for Electric Vehicle Travel Optimization (2012)

Soft Constraint Logic Programming is a natural and flexible declarative programming formalism, which allows to model and solve real-life problems involving constraints of different types. In this paper, after providing a slightly more general and elegant presentation of the framework, we show how we can apply it to the e-mobility problem of coordinating electric vehicles in order to overcome both energetic and temporal constraints and so to reduce their running cost. In particular, we focus on the journey optimization sub-problem, considering sequences of trips from a user's appointment to another one. Solutions provide the best alternatives in terms of time and energy consumption, including route sequences and possible charging events.

Novel biological metamaterials, nanoscale optical devices, and Polarimetric Exploratory Data Analysis (pEDA) (2010)

This study reports that certain biological macromolecules, colloidal suspensions, or organic molecular structures, with very large optical activities, exhibit enhanced transmission, backscattering and signal characteristics. Although by definition, these molecular nanocomposite structures can be classified as metamaterials, whether these macromolecules exhibit uniquely defined metamaterial characteristics, deserves a careful study before any assessment can be made. Based on the above, a new optical polarimetric metrics definition is introduced, namely, the Polarimetric Exploratory Data Analysis (pEDA) aimed to quantify the signal characteristics of photons interacting with optically active media, in terms of enhanced contrast and potential discriminant descriptors, without excluding expansion of the same metrics to other areas of research.
When one isn't enough (2003)

Screen space is a limited resource for computer users-multiple monitors are one means of workspace expansion, and desktops are yet another way to increase screen real-estate. We present a taxonomy of organization strategies based on our observations during a series of interviews with virtual desktop users. Additionally, we explore causes of varying user preferences for physical versus virtual means of screen-space expansion. Finally, we discuss the design implications of our findings.
N,N′-Bis(2,6-dichlorobenzyl)ethylenediimine (2007)

In the centrosymmetric title compound, C16H12Cl4N2, the asymmetric unit is one half-mol­ecule. Weak van der Waals inter­actions between the mol­ecules are effective in the mol­ecular packing. This is the first reported structure of a chloro-substituted benzaldehyde derivative that can potentially form a tetra­dentate ligand.
Design of multiple-beam gratings for far-IR applications (1991)

Automatic Pool Allocation: Compile-Time Control of Data Structure Layout in the Heap (2004)

Despite the potential importance of data structure layouts and traversal patterns, compiler transformations on pointer-intensive programs are performed primarily using pointer analysis, and not by controlling and using information about the layout of high-level data structures. This paper describes a compiler transformation called \\emph{Automatic Pool Allocation} that segregates instances of ``logical'' data structures in the heap into distinct pools, and allows different heuristics to be used to partially control the internal layout of those data structures. Because these are rigorous transformations, their results, combined with pointer analysis information, can be used to perform further compiler analyses and transformations, and we briefly list a few examples. Automatic Pool Allocation also provides several direct performance benefits for pointer intensive programs, most importantly, that traversals of a logical data structure allocated to a separate pool can have better spatial locality and smaller working sets. We evaluate the performance and cache behavior of the code transformed by the automatic pool allocation transformation on a series of heap-intensive and general-purpose benchmarks, and find that it speeds up several C programs by 10-40\\% percent or more, and does not hurt (or help) other programs.

Isomer formation in the binding of [PtCl2(cis-cyclohexane-1,3-diamine)] to oligonucleotides and the X-ray crystal structure of [PtCl2(cis-cyclohexane-1,3-diamine)]·dimethylformamide† (2001)

The crystal structure of [PtCl2(cis-1,3-chxn)] (cis-1,3-chxn = (cis-cyclohexane-1,3-diamine)) as the dimethyformamide solvate is reported. When [PtCl2(cis-1,3-chxn)] binds to d(GpG), two isomers are formed that are readily separated by HPLC. Both the HPLC and GFAAS studies of the products show that the isomers form in a 1 ∶ 1 ratio. Competition experiments involving d(GpG) and the aquated and nonaquated forms of [PtCl2(cis-1,3-chxn)] and [PtCl2(NH3)2] showed that the slower binding of the former complex was due to slower aquation and not steric bulk. 1D and 2D NMR studies of the [Ptd(GpG)(cis-1,3-chxn)] isomers showed that both the dinucleotide and the diamine were highly fluxional, even at low temperatures, and this prevented formation of strong cross peaks in the NOESY and ROESY spectra and hence identification of the isomers. [PtCl2(cis-1,3-chxn)] was reacted with a 52-mer oligonucleotide having six GpG binding sites and the products were enzymatically digested and separated by HPLC. The two [Ptd(GpG)(cis-1,3-chxn)] stereoisomers were the only significant platinated products, again forming in a 1 ∶ 1 ratio although it had been anticipated that stereoselectivity would be observed in the reaction with the 52-mer because of the potential for steric interactions with the cis-1,3-chxn ligand. Molecular modelling revealed that the observed lack of stereoselectivity was due to the ability of the cis-1,3-chxn ligand to adopt a continuum of conformations that allow it to avoid severe steric clashes with the DNA.
A Qualitative Approach to Content-Based Color Image Retrieval with Chinese Captions (2000)

This paper presents an intelligent method of retrieving images with Chinese captions from an image database. We combine color, shape and spatial features of the image to index and measure the similarity of images. As a technical contribution, a Seed-Filling like algorithm that could extract the shape and spatial relationship feature of images is proposed. Due to the difficulty of determining how far objects separate, we use qualitative spatial relations to analyze object similarities. Also, the system is incorporated with a visual interface and a set of tools, which allows the users to express the query by specifying or sketching the images conveniently. Besides, our feedback learning mechanism enhances the precision of retrieval. Our experience shows that the system is able to retrieve image information efficiently by the proposed approaches.
Transmitter Phenotypic Expression in the Embryo (1981)

The initial appearance and development of noradrenergic and adrenergic phenotypic characters was studied in the rat embryo by immunocytochemical methods. Tyrosine hydroxylase and dopamine-beta-hydroxylase (noradrenergic enzymes) appeared at 11.5 days of gestation (Day E 11.5; 27-30 somites) in sympathetic ganglion primordia and in cells of the gut. While tyrosine hydroxylase and dopamine beta-hydroxylase immunoreactivity increased progressively in ganglion primordia, the enzymes disappeared in the gut cells after E 13.5. However, the gut cells themselves persisted, as indicated by the high-affinity uptake of noradrenaline (norepinephrine). Consequently, initial appearance of noradrenergic characters does not ensure persistence and subsequent development, indicating that early phenotypic expression is a mutable process. This contention was supported by the observations that pharmacological stress of pregnant rats in the form of reserpine, or treatment with glucocorticoids, prolonged the appearance of catecholamines in the gut cells. Thus, maternal-embryonic relations in general, and maternal glucocorticoids in particular, may influence embryonic phenotypic expression. Treatment of embryos with nerve growth factor also prolonged the appearance of noradrenergic characters in the gut cells. Expression of the adrenergic phenotype was apparently regulated differently from noradrenergic expression, since phenylethanolamine-N-methyltransferase (PNMT), the adrenaline-(epinephrine)-synthesizing enzyme, was undetectable in ganglion primordia and gut cells. PNMT initially appeared at E 17.5 in cells which had migrated to be adrenal anlage. Extensive studies suggest that the initial appearance of PNMT occurs independently of glucocorticoid regulation, while subsequent development is dependent on corticoids.
DDe la biologie au silicium : une retine bio-inspiree analogique pour un capteur de vision "intelligent" adaptatif (1999)

Dans les systemes de traitement d'images, le capteur de vision est un composant de phototransduction dont le role est de convertir un signal lumineux en un signal electrique. L'evolution des technologies micro-electroniques permet actuellement d'integrer un ensemble de transistors autour de l'element photosensible. Ceci est le fondement architectural du capteur de vision intelligent qui associe phototransduction et traitement d'images dans le plan focal. Ce circuit est compose d'une matrice de cellules de traitement photosensibles ou pixels, interconnectes entre proches voisins, qui forment un reseau qui effectue des taches de vision precoce, dites aussi de bas-niveau. Notre reseau est inspire d'un modele electrique analogique de la retine des vertebres. Celui-ci est un filtre spatiotemporel analogue a celui releve en biologie. Il effectue une extraction de contours et une detection des objets en mouvement. Le pixel integre un systeme bio-inspire d'adaptation aux conditions lumineuses. En fonction de la luminosite moyenne, il optimise la phototransduction et adapte la fonction de transfert du filtre. Il en resulte une sensibilite aux contrastes amelioree et une robustesse au bruit accrue dans des conditions de faibles luminosites. Une matrice de 64 64 pixels a ete concue en technologie cmos 0. 5um. Ce capteur de vision analogique de 70mm#2 permet, en temps reel, une extraction de contours efficace et une detection de mouvement sur une large gamme de vitesse. Un circuit de test a permis de montrer l'apport de l'adaptation aux conditions lumineuses. Ces capteurs de vision, utilises dans une camera, montrent l'interet et l'efficacite de leur filtrage. Les interfaces de la matrice ont ete concus de maniere a faciliter l'emploi de ces circuits dans des systemes de vision artificielle. Cela permettra de mettre en evidence les avantages lies a leur utilisation dans des applications de teledetection, de reconnaissance de formes, de visiophonie, de conduite de robot
Effect of polyamines on the activity of malarial α‐like DNA polymerase (1990)

DNA polymerase from the malarial parasite Plasmodium falciparum required Mg2+ for activity, Putrescine (1 mM) caused a twofold increase in enzyme activity in the presence of a suboptimal concentration of MgCl2 (2 mM). Spermidine (1.5-2.0 mM) or spermine (0.1-0.3 mM) increased the activity of malarial DNA polymerase, in the presence of 2 mM MgCl2, by factors of 6 and 3-5, respectively. The activity of DNA polymerase from calf thymus or from NIH 3T3 cells transformed by the ras oncogene were not stimulated by these polyamines to the same extent. These findings suggest that in malaria-infected erythrocytes, polyamines, at physiological concentrations, serve as a cofactor for the parasitic alpha-like DNA polymerase. Malarial parasites grown in cultured human erythrocytes did not synthesize DNA after treatment with alpha-difluoromethylornithine, which caused polyamine depletion in the infected cells. DNA synthesis was resumed after adding putrescine to the polyamine-depleted cultures. DNA synthesis was also initiated when actinomycin D was added along with putrescine to polyamine-depleted cells. It thus appears that polyamines are essential for the translation of the DNA polymerase mRNA and that polyamines play an important role in regulating the cell cycle of the malarial parasite.

Experimental Interference Robustness Evaluation of IEEE 802.15.4-2015 OQPSK-DSSS and SUN-OFDM Physical Layers for Industrial Communications (2019)

In this paper, we experimentally evaluate and compare the robustness against interference of the OQPSK-DSSS (Offset Quadrature Phase Shift Keying-Direct Sequence Spread Spectrum) and the SUN-OFDM (Smart Utility Network-Orthogonal Frequency Division Multiplexing) physical layers, as defined in the IEEE 802.15.4-2015 standard. The objective of this study is to provide a comprehensive analysis of the impact that different levels of interference produce on these modulations, in terms of the resulting PDR (Packet Delivery Ratio) and depending on the length of the packet being transmitted. The results show that the SUN-OFDM physical layer provides significant benefits compared to the ubiquitous OQPSK-DSSS in terms of interference robustness, regardless of the interference type and the packet length. Overall, this demonstrates the suitability of choosing the SUN-OFDM physical layer when deploying low-power wireless networks in industrial scenarios, especially taking into consideration the possibility of trading-off robustness and spectrum efficiency depending on the application requirements.
