description: This work presents a highly optimized computational framework for the Discrete Dipole Approximation, a numerical method for calculating the optical properties associated with a target of arbitrary geometry that is widely used in atmospheric, astrophysical and industrial simulations. Core optimizations include the bit-fielding of integer data and iterative methods that complement a new Discrete Fourier Transform (DFT) kernel, which efficiently calculates the matrix vector products required by these iterative solution schemes. The new kernel performs the requisite 3-D DFTs as ensembles of 1-D transforms, and by doing so, is able to reduce the number of constituent 1-D transforms by 60% and the memory by over 80%. The optimizations also facilitate the use of parallel techniques to further enhance the performance. Complete OpenMP-based shared-memory and MPI-based distributed-memory implementations have been created to take full advantage of the various architectures. Several benchmarks of the new framework indicate extremely favorable performance and scalability. OpenDDA is available following the usual open source regulations from http://www.opendda.org

description: Land degradation due to bush encroachment and drought threatens the well-being of land users and forage production in the semi-arid savannas of southern Africa. This study aimed to analyse how herbaceous vegetation in the Kalahari savanna can recover from drought, and how this is affected by previously implemented bush control measures. We compared plant species composition and diversity of the herbaceous layer across a drought-release (2021) and post-drought (2022) year within two land use types (game and livestock) in bush-encroached and controlled areas, respectively. Diversity decreased significantly during the post-drought year. Annual species dominated in the drought-release year, which were replaced by perennial forbs and dwarf shrubs in the post-drought year. Selective bush control enhanced herbaceous species abundance and richness due to decreased competition. The species richness was higher in the game ranch compared to the cattle farm during the drought-release year. Herbaceous abundance, however, increased on the cattle farm. The management strategies, feeding behaviour and animal movement may have contributed to these differences in these two contrasting land use types. This study showed that herbaceous plant communities can recover rapidly after a drought period and in areas where bush control was applied.

description: We report on experimental implementation of the optimal universal asymmetric 1->2 quantum cloning machine for qubits encoded into polarization states of single photons. Our linear optical machine performs asymmetric cloning by partially symmetrizing the input polarization state of signal photon and a blank copy idler photon prepared in a maximally mixed state. We show that the employed method of measurement of mean clone fidelities exhibits strong resilience to imperfect calibration of the relative efficiencies of single-photon detectors used in the experiment. Reliable characterization of the quantum cloner is thus possible even when precise detector calibration is difficult to achieve.

description: We developed a method for estimating the positional distribution of transcription fac-tor (TF) binding sites using ChIP-chip data, and applied it to recently published experiments on binding sites of nine TFs; OCT4, SOX2, NANOG, HNF1A, HNF4A, HNF6, FOXA2, USF1 and CREB1. The data were obtained from a genome-wide cov-erage of promoter regions from 8kb upstream of the Transcription Start Site (TSS) to 2kb downstream. The number of target genes of each TF ranges from few hundred to several thousand. We found that for each of the nine TFs the estimated binding site distribution is closely approximated by a mixture of two components: a narrow peak, localized within 300 base pairs upstream of the TSS, and a distribution of almost uni-form density within the tested region. Using Gene Ontology and Enrichment analysis, we were able to associate (for each of the TFs studied) the target genes of both types of binding with known biological processes. Most GO terms were enriched either among the proximal targets or among those with a uniform distribution of binding sites. For example, the three stemness-related TFs have several hundred target genes that belong to "development" and "morphogenesis" whose binding sites belong to the uniform dis-tribution.

description: In this paper, we consider the natural complex Hamiltonian systems with homogeneous potential $V(q)$, $q\in\C^n$, of degree $k\in\Z^\star$. The known results of Morales and Ramis give necessary conditions for the complete integrability of such systems. These conditions are expressed in terms of the eigenvalues of the Hessian matrix $V"(c)$ calculated at a non-zero point $c\in\C^n$, such that $V'(c)=c$. The main aim of this paper is to show that there are other obstructions for the integrability which appear if the matrix $V"(c)$ is not diagonalizable. We prove, among other things, that if $V"(c)$ contains a Jordan block of size greater than two, then the system is not integrable in the Liouville sense. The main ingredient in the proof of this result consists in translating some ideas of Kronecker about Abelian extensions of number fields into the framework of differential Galois theory.

A function generator for a time sequential analogue computer.
Creators: name: Stacey, John Sydney
Publisher: name: University of British Columbia
Year: 2012

description: The large numbers of functions required in computations concerned with systems simulation have often resulted in function generators being very bulky, inflexible and expensive pieces of apparatus. This is because a separate system is often required for each function to be generated. The method proposed here enables a large number of functions to be generated by a minimum of equipment. Moreover, the arrangement is very flexible and should prove accurate to within 1%. This unit is designed for a time sequential analogue computer. This method of computation enables the functions F(X) to be stored and each sampled at a discrete value of X by a single sampling system. The functions are stored as photographs mounted around the surface of a rotating drum. Each function is sampled in turn by a beam of light and a photocell system. The position of the beam, (controlled by a galvanometer), determines the value of X at which the function is being sampled. The output from the photocell is arranged to indicate the value of F(X). In this unit up to 1000 samples per second can be made from 15 different functions - all at different values of X if necessary. The flexibility is such that the number of functions stored could be greatly exceeded with very little extra equipment.

description: In this study we report an optimized single-shot diffusion-weighted echo planar imaging sequence that can visualize the olfactory tracts with CSD fiber tracking, 3D volume rendering and f-MRI. The olfactory tracts are localized in the olfactory grooves of the ethmoidal bone, running posteriorly through the olfactory sulci connecting to the inferior surfaces of the frontal lobes. Distally the tracts are enlarged into the olfactory bulbs and proximally they split into medial, intermediate and lateral striae and from here the axon projecting to the olfactory cortex, divided into five main areas: the anterior olfactory nucleus, which connects the two olfactory bulbs through a portion of the anterior commissure; the piriform cortex; parts of the amigdala, the olfactory tubercle and entorinal cortex; not all of these connections through the thalamus. Moreover, olfactory information is transmitted from the amygdala to the hypothalamus and from the entorinal area to the hippocampus.The olfactory tracts are difficult to depict with MRI diffusion-weighted imaging due to the high sensitivity to susceptibility artifacts at the base of the skull (Duprez and Rombaux, 2010). Ten subjects were examined; in five healthy subjects the olfactory tracts could be fiber tracked with the diffusion-weighted sequence, while in five anosmic PD patients, altered olfactory tracts were visualized. Furthermore, olfactory stimuli were applied during fMRI scanning to show the area BOLD activation to advance our understanding of olfactory dysfunction in PD patients compared to control. Olfactory function was established using the “Sniffin’ Sticks” test battery.This study of the olfactory tracts promise to visualize the anatomic organization and to facilitate the identification of different hyposmic and anosmic entities caused by neurodegenerative disorders or post-traumatic and congenital disfunctions.

description: Secondary arm lymphedema (LE) is among the most dreaded chronic complications in cancer patients that occurs when axillary lymphatic drainage from the arm is interrupted because of axillary lymph node dissection and/or axillary radiation (Ikeda et al., 2014). LE is characterized by accumulation of protein-rich interstitial fluid in the arm, resulting in tissue swelling. Subsequent swelling can cause pain, discomfort, heaviness, distortion, and reduced mobility and function, thereby affecting quality of life. With increased survival rates there is greater emphasis on enhancing quality of life after treatments (Armer et al., 2003), but the secondary LE remains a problem even with modern treatment modalities. Many treatment options for lymphedema are available, but none offer a permanent reduction or elimination of arm swelling (McKenzie and Kalda, 2003). Recent researches support the positive effects deriving from the regular participation in structured adapted physical activity programs in preventing or attenuating cancer treatment-related impairments improving the quality of life (Mirandola et al., 2013). In this context, the aim of our study was to propose and evaluate a specific exercise, planned by an adapted exercise specialist, to reduce LE and improve strenght and mobility of the arm, as well as quality of life in cancers survivors. We recruited by Cancer Rehabilitation Center of Florence 20 cancer survivors with chronic moderate-severe arm lymphedema, divided randomly into 4 groups according to the different protocol for duration, frequency and intensity of proposed exercise. Outcome measures, included the arm circumference, ROM of arm and hand-wrist, strenght (hand grip test) and quality of life (ULL27 questionaire), were assessed at baseline, in itinere (1, 2 and 3 months) and post-intervention (6 months). Our preliminary results demonstrated that a structured exercise (10 repetitions x 3 with 1 minute break once a day for 3 times per week) improved shoulder function, reduced and managed LE cancer survivors.

description: Presented here are the details of the astrometric reductions from the x,y data to mean Right Ascension (RA), Declination (Dec) coordinates of the third U.S. Naval Observatory (USNO) CCD Astrograph Catalog (UCAC3). For these new reductions we used over 216,000 CCD exposures. The Two-Micron All-Sky Survey (2MASS) data are extensively used to probe for coordinate and coma-like systematic errors in UCAC data mainly caused by the poor charge transfer efficiency (CTE) of the 4K CCD. Errors up to about 200 mas have been corrected using complex look-up tables handling multiple dependencies derived from the residuals. Similarly, field distortions and sub-pixel phase errors have also been evaluated using the residuals with respect to 2MASS. The overall magnitude equation is derived from UCAC calibration field observations alone, independent of external catalogs. Systematic errors of positions at UCAC observing epoch as presented in UCAC3 are better corrected than in the previous catalogs for most stars. The Tycho-2 catalog is used to obtain final positions on the International Celestial Reference Frame (ICRF). Residuals of the Tycho-2 reference stars show a small magnitude equation (depending on declination zone) that might be inherent in the Tycho-2 catalog.

description: GnRH neurons are a peculiar hypothalamic subpopulation crucially involved in the control of the reproductive axis. As well established in several animal models, the kisspeptin (KISS1)/KISS1 receptor (KSS1R) system plays a master role in the control of GnRH neurons, however, investigations in humans are strongly hampered by the anatomical distribution of these neurons, scattered within the preoptic area of the hypothalamus. This study was aimed at establishing a human hypothalamic primary cell culture with GnRH neuron features. Brains were recovered from 11-12 week-old human fetuses, then hypothalamic tissue, lining the 3rd ventricle, was dissected and processed for cell culture isolation. The primary cultures obtained were first characterized using flow cytometry and showed a mixed composition with the majority of cells (92±8 %) positive for the neuronal marker MAP2 and a low percentage of cells positive for the glial marker GFAP (13.5±9 %). Interestingly, among the neuronal population about 80% were GnRH-positive cells (77.8±20 %). Gene expression profiling, immunofluorescence and western blot analyses confirmed that these cells expressed GnRH, as well as KISS1R. Hence, electrophisiological studies were performed to investigate if these cells responded to kisspeptin (Kp) stimulation. Using the voltageclamp technique, we found that Kp (100nM or 1μM) induced a clear depolarizing response. Moreover, depolarizing effects of Kp involved transient receptor potential channels (TRPC), as expected by KISS1R activation (1). This is the first human hypothalamic cellular model with a GnRH neuron phenotype, representing a new tool for the investigation of human GnRH neuron biology.

Theoretical and experimental determinations of the amplitude probability distribution and of the autocorrelation function of the signal were made. On the basis of tests and observations made, it is concluded that the signal generated may be considered a noise signal having a near-Gaussian amplitude probability distribution, very little correlation for time-shifts greater than 30 seconds, and a bandwidth of about 60 cps.

description: The need to reduce the level of criminal activity has preoccupied the attention of policymakers which has led to the exploration of feasible, alternative routes to achieve United Nations’ Sustainable Development Goal -16. This phenomenon has been the present practice of most developing countries such as Nigeria that is inundated with higher level of crime rate. This study examines the possibility of using fiscal policy tools for crime control by employing Dynamic Ordinary Least Square (DOLS) technique on Nigerian data over a period of 1986-2019. It also examines the causal links between the variables via the Toda-Yamamoto Granger causality. The following findings emerged: (1) Expansionary fiscal policy reduces crime behaviour in Nigeria. This result is robust when public spending is used as a proxy for fiscal policy. (2) There is a one-way causality moving from crime rate to fiscal deficit. (3) There is a one way causality moving from urbanization to crime rate. (4) We find a two-way causality between inflation and fiscal deficit. In terms of policy implications, these findings suggest that fiscal policy can be used to curb crime behaviour in the developing countries.

Anisotropic clustering of inertial particles in homogeneous shear flow

description: Recently, clustering of inertial particles in turbulence has been thoroughly analyzed for statistically homogeneous isotropic flows. Phenomenologically, spatial homogeneity of particles configurations is broken by the advection of a range of eddies determined by the Stokes relaxation time of the particles which results in a multi-scale distribution of local concentrations and voids. Much less is known concerning anisotropic flows. Here, by addressing direct numerical simulations (DNS) of a statistically steady particle-laden homogeneous shear flow, we provide evidence that the mean shear preferentially orients particle patterns. By imprinting anisotropy on large scales velocity fluctuations, the shear indirectly affects the geometry of the clusters. Quantitative evaluation is provided by a purposely designed tool, the angular distribution function of particle pairs (ADF), which allows to address the anisotropy content of particles aggregates on a scale by scale basis. The data provide evidence that, depending on the Stokes relaxation time of the particles, anisotropic clustering may occur even in the range of scales where the carrier phase velocity field is already recovering isotropy. The strength of the singularity in the anisotropic component of the ADF quantifies the level of fine scale anisotropy, which may even reach values of more than 30% direction-dependent variation in the probability to find two close-by particles at viscous scale separation.

description: Oxaliplatin-based regimens are effective in metastasised advanced cancers. However, a major limitation to their use is represented by neurotoxicity leading to peripheral neurophaty (Wolf et al., 2008). In this study we evaluate the effects of an immunotherapeutic agent (Gc protein-derived macrophage activating factor, GcMAF) in preventing oxaliplatin-induced neuronal damage and in restoring microglial activation. The effects of oxaliplatin was studied in human neurons (SH-SY5Y) and microglial cells (c13-nj). Cell density, morphology and viability as well as production of cAMP and expression of vascular endothelial growth factor (VEGF), markers of neuron regeneration and markers of microglia activation were determined. GcMAF reverted the damage inflicted by oxaliplatin on human neurons and preserved their viability; it also increased cAMP production, VEGF and neuromodulin expression. GcMAF did not revert the effects of oxaliplatin on microglial cell viability. However, it induced microglial activation resulting in an increased expression of a specific marker without any increase in cell number. Our results demonstrate that GcMAF may significantly contribute to neutralize the neurotoxicity induced by oxaliplatin, at the same time concurring to an integrated anti-cancer effect.

We analyze how a subsystem independent measure of entanglement, the purity related to the su(3) algebra, scales for increasing number of atoms and signals correctly the quantum phase transition between two dynamical regimes in a specific arrangement. Moreover, this measure, which is intrinsically related to particle entanglement, also depicts if some squeezing is occurring when we consider the system's ground state.

description: By means of ab initio calculations within the density functional theory, we have found that B80 fullerenes can condense to form stable face-centered-cubic fcc solids. It is shown that when forming a crystal, B80 cages are geometrically distorted, the Ih symmetry is lowered to Th, and four boron-boron chemical bonds are formed between every two nearest neighbor B80 cages. The cohesive energy of B80 fcc solid is 0.23 eV/atom with respect to the isolated B80 fullerene. The calculated electronic structure reveals that the fcc B80 solid is a metal. The predicted solid phase would constitute a form of pure boron and might have diverse implications. In addition, a simple electron counting rule is proposed, which could explain the stability of B80 fullerene and the recently predicted stable boron sheet.

description: We extend the massless dipole formalism of Catani and Seymour, as well as its massive version as developed by Catani, Dittmaier, Seymour and Trocsanyi, to arbitrary helicity eigenstates of the external partons. We modify the real radiation subtraction terms only, the primary aim being an improved efficiency of the numerical Monte Carlo integration of this contribution as part of a complete next-to-leading order calculation. In consequence, our extension is only applicable to unpolarized scattering. Upon summation over the helicities of the emitter pairs, our formulae trivially reduce to their original form. We implement our extension within the framework of Helac-Phegas, and give some examples of results pertinent to recent studies of backgrounds for the LHC. The code is publicly available. Since the integrated dipole contributions do not require any modifications, we do not discuss them, but they are implemented in the software.

description: The male germ cell undergoes a proliferative step of amplification of the cell number, a meiotic step that reduces the genome to haploid, and a morphological differentiation stage to form spermatozoa. Although each phase requires a dynamic repertoire of functional factors, transcription is not always active in spermatogenesis, being characterized by a mitotic phase in spermatogonia, a meiotic phase in pachytene spermatocytes and a post-meiotic phase in round spermatids. We have performed deep-sequencing analysis of the transcriptome of purified populations of pachytene spermatocytes and round spermatids. We generated strend-specific RNAseq data for polyadenylated RNAs, resulting in >100 million 100bp mapped reads for each sample. Comparison of the spermatid versus spermatocytes transcriptome revealed 5508 up regulated and 7218 down-regulated genes in post-meiotic germ cells. Cell cycle and splicing were the most significantly up regulated pathways in post-meiotic versus meiotic cells. As for the splicing, 3278 exons in 2185 genes were differentially regulated in spermatids and spermatocytes. The most represented classes were alternative first exons, intron retention, alternative last exons and exon cassettes. These changes were accompanied by changes in the expression of key splicing factors, like the overall down regulation of the serine-arginine rich (SR) family, involved in positive regulation of constitutive and alternative splicing events. Our results indicate that male germ cells extensively modify the pattern of gene expression during the meiotic divisions and identify key molecular players involved in this transition. The global reduction in the SR protein family, known positive regulators of splicing events, may drive the extensive changes in alternative splicing observed between meiotic and post-meiotic germ cells.

Born in Brussels, Vesalius studied in Paris and worked in Louvain, Basle, Pisa and Padua. The prime importance of his contribution to post-Renaissance modern anatomy development is well recognized. Vesalius recorded his new approach to anatomy in 1543 in De humani corporis fabrica, dedicated to Charles V, the Holy Roman Emperor, and in the Epitome, a short version of the fabrica. This work comprises seven books written in Latin where the author challenged the Galen’s authority on several observations made in animals. Remarkably, Vesalius insisted that anatomy must be studied only by means of human dissections. More than 200 criticisms were addressed against the mistakes of the past tradition. The fabrica is also a work of beauty, bearing more than 200 wonderful illustrations attributed to the Titian’s pupil Jan van Calcar. The background appearing in the six muscular illustrations seems to refer to the Paduan countryside. When appropriately combined, these illustrations render a continuous landscape. The numerous historiated initials also show cherubs or men acting in anatomical procedures. In spite of the appreciable anatomical illustrations previously realized by Leonardo da Vinci and Charles Estienne, Vesalius had the merit to provide a more comprehensive and systematic anatomical book. The hieratic medieval dissection of Mondino de’ Liuzzi, with the recognition of three different roles (lector, sector and ostensor), was completely changed by Vesalius. Importantly, the frontispiece of the fabrica contains several symbolic messages, which announce the anatomical revolution. Firstly, it shows Vesalius itself who recapitulates the three roles: he stands at the centre of the scene dissecting a cadaver in a crowded anatomical theatre. A monkey and a dog are placed at the bottom edges of the scene. Finally, two lower ranking surgeons, who traditionally did the actual work of dissection, are ridiculed while quarrelling under the dissecting table. It must be noted that the success of the fabrica was due not only to its new scientific insights, but also as a result of the accurate self-promotion of the author who personally supervised each detail and entrusted with the publication Johannes Oporinus, one of the most important printers of the 16th century. The modern technologies, including the virtual reality, seem to substitute the anatomical dissection. It must be avoided to create a modern Galen-like technological authority that leads to forget that the human body is the unique truth. The legacy of the masterpiece of Vesalius and its scientific revolution would linger even into the present and future times.

description: Celiac disease (CD) is an inflammatory disorder of the small Intestine activated in genetically predisposed individuals by the ingestion of gluten from wheat and related cereals (1). The role of adaptative immunity in CD has been widely investigated. However, also innate immunity can have a role in the development of the disease, and it could involve the alteration of proteins expression (determined either at transcriptional and post-transcriptional level). Post-transcriptional regulation could involve also small non coding RNAs (micro RNA, miRNA). In this study we have analyzed miRNAs expression in duodenal biopsies of controls and celiac patients subdivided into 2 groups (Marsh 3A-B and Marsh 3C) according to the severity of the intestinal lesion. Microarray analysis demonstrated that miR-192-5p is significantly down-regulated in biopsies of Marsh 3C CD patients. Several studies suggested a possible role for miR-192-5p in diseases with alteration of the immune system (2, 3). In this study we identified possible target genes by in silico analysis, including CXCL2 and NOD2, molecules involved in innate immunity. qRT-PCR and western blotting demonstrated that both mRNA and protein expression were higher in CD patients compared to controls. qRT-PCR performed after laser microdissection and immunohistochemistry prove that miR-192-5p and CXCL2 and NOD2 mRNA were present principally in villus epithelium (both in controls and in CD patients) suggesting a direct interaction between miR-192-5p and the two target proteins. In conclusion the results of the present study support the role of miRNAs in regulating the innate immunity in celiac disease.
