What ACL Means to Me

I joined the Association of Christian Librarians (ACL) in 1997, at a time when I was seeking God’s will for my future in library work.The previous year, I had been unexpectedly let go after eight years in a Bible college library position due to downsizing, and my heart was still in academic library work. I found ACL to be far more than a facilitator for library job searching. This association is foremost a Christian one, and provided something far better than networking just to advance oneself. Attending my first ACL conference in 1997, I was greatly encouraged by a group of library colleagues with whom I could share my heart and search for God’s will, with the assurance that they understood and would pray for me. Here I could be developed and challenged both professionally and spiritually – what more could I ask for? I determined to attend the ACL conference every year

An Iron Age II tomb with Phoenician items at Khirbet Bir el-Kharayib, Central Palestine

In 2017, during a salvage excavation carried out by the Department of Antiquities and Cultural Heritage of Palestine, an Iron Age shaft tomb close to the site of Khirbet Bir el-Kharayib in Central Palestine came to light. The funerary equipment of the tomb goes within the Iron Age IIA pottery tradition. Vessels of this period primarily consist of Red Slip Ware bowls and juglets, Black Slip Ware juglets, Simple Ware jars, jugs and juglets, and Cooking Ware pots. A Bichrome Ware jug, a bronze bowl and a zoomorphic figurine complete the funerary set

Observations of annual modulation in direct detection of relic particles and light neutralinos

The long-standing model-independent annual modulation effect measured by the DAMA Collaboration, which fulfills all the requirements of a dark matter annual modulation signature, and the new result by the CoGeNT experiment that shows a similar behavior are comparatively examined under the hypothesis of a dark matter candidate particle interacting with the detectors' nuclei by a coherent elastic process. The ensuing physical regions in the plane of the dark matter-particle mass versus the dark matter-particle nucleon cross-section are derived for various galactic halo models and by taking into account the impact of various experimental uncertainties. It is shown that the DAMA and the CoGeNT regions agree well between each other and are well fitted by a supersymmetric model with light neutralinos which satisfies all available experimental constraints, including the most recent results from CMS and ATLAS at the CERN Large Hadron Collider.Comment: 13 pages, 7 figure

DAMA annual modulation effect and asymmetric mirror matter

The long-standing model-independent annual modulation effect measured by DAMA Collaboration is examined in the context of asymmetric mirror dark matter, assuming that dark atoms interact with target nuclei in the detector via kinetic mixing between mirror and ordinary photons, both being massless. The relevant ranges for the kinetic mixing parameter are obtained taking into account various existing uncertainties in nuclear and particle physics quantities as well as characteristic density and velocity distributions of dark matter in different halo models.Comment: 27 pages, 5 figures, 2 tables; version in publication on Eur. Phys. J.

MicroRNA-222 regulates muscle alternative splicing through Rbm24 during differentiation of skeletal muscle cells

A number of microRNAs have been shown to regulate skeletal muscle development and differentiation. MicroRNA-222 is downregulated during myogenic differentiation and its overexpression leads to alteration of muscle differentiation process and specialized structures. By using RNA-induced silencing complex (RISC) pulldown followed by RNA sequencing, combined with in silico microRNA target prediction, we have identified two new targets of microRNA-222 involved in the regulation of myogenic differentiation, Ahnak and Rbm24. Specifically, the RNA-binding protein Rbm24 is a major regulator of muscle-specific alternative splicing and its downregulation by microRNA-222 results in defective exon inclusion impairing the production of muscle-specific isoforms of Coro6, Fxr1 and NACA transcripts. Reconstitution of normal levels of Rbm24 in cells overexpressing microRNA-222 rescues muscle-specific splicing. In conclusion, we have identified a new function of microRNA-222 leading to alteration of myogenic differentiation at the level of alternative splicing, and we provide evidence that this effect is mediated by Rbm24 protei

Narrative Health Communication and Behavior Change: The Influence of Exemplars in the News on Intention to Quit Smoking.

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients\u27 narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with an exemplar experienced greater narrative engagement compared to those reading an article without an exemplar. Those who reported more engagement were in turn more likely to report greater smoking cessation intentions

Final results of an experiment to search for 2beta processes in zinc and tungsten with the help of radiopure ZnWO4 crystal scintillators

A search for the double beta decay of zinc and tungsten isotopes has been performed with the help of radiopure ZnWO4 crystal scintillators (0.1-0.7 kg) at the Gran Sasso National Laboratories of the INFN. The total exposure of the low background measurements is 0.529 kg yr. New improved half-life limits on the double beta decay modes of 64Zn, 70Zn, 180W, and 186W have been established at the level of 10^{18}-10^{21} yr. In particular, limits on double electron capture and electron capture with positron emission in 64Zn have been set: T_{1/2}(2\nu 2K) > 1.1 10^{19} yr, T_{1/2} (0\nu 2\epsilon) > 3.2 10^{20} yr, T_{1/2} (2\nu \epsilon \beta^+) > 9.4 10^{20} yr, and T_{1/2} (0\nu \epsilon \beta^+) > 8.5 10^{20} yr, all at 90% C.L. Resonant neutrinoless double electron capture in 180W has been restricted on the level of T_{1/2} (0\nu 2\epsilon) > 1.3 10^{18} yr. A new half-life limit on alpha transition of 183W to the metastable excited level 1/2^- 375 keV of 179Hf has been established: T_{1/2} > 6.7 10^{20} yr.Comment: This is an author-created, un-copyedited version of an article published in J.

Caractérisation thermique des matériaux pour mémoires à changement de phase à haute température et échelle submicrométrique.

Les PCM (Phase Change Memory) développés par l’industrie microélectronique utilisent des verres chalcogénures des systèmes Ge-Sb-Te pour assurer le stockage de données informatiques par changement de structures cristallines. Le principe de stockage de l'information repose sur la différence de résistivité électrique entre l’état amorphe et l’état cristallin de ces verres, le passage entre ces différents états s’effectuant par chauffage (effet Joule). Il est fondamental, afin de maîtriser ces phénomènes de changement de phase pour le stockage des données, de connaître les propriétés thermiques de ces matériaux. On mesure ainsi la conductivité thermique de couche mince de faible épaisseur (100 nm – 800 nm) sur une plage de température de 25°C à 400°C. La résistance d’interface entre le GST et le diélectrique utilisé dans les PCM (ici du SiO2) est aussi estimée
