The Projective Line Over the Finite Quotient Ring GF(2)[xx]/<x3−x>< x^{3} - x> and Quantum Entanglement I. Theoretical Background

The paper deals with the projective line over the finite factor ring $R\_{\clubsuit} \equiv$ GF(2)[$x$]/$$. The line is endowed with 18 points, spanning the neighbourhoods of three pairwise distant points. As $R\_{\clubsuit}$ is not a local ring, the neighbour (or parallel) relation is not an equivalence relation so that the sets of neighbour points to two distant points overlap. There are nine neighbour points to any point of the line, forming three disjoint families under the reduction modulo either of two maximal ideals of the ring. Two of the families contain four points each and they swap their roles when switching from one ideal to the other; the points of the one family merge with (the image of) the point in question, while the points of the other family go in pairs into the remaining two points of the associated ordinary projective line of order two. The single point of the remaining family is sent to the reference point under both the mappings and its existence stems from a non-trivial character of the Jacobson radical, ${\cal J}\_{\clubsuit}$, of the ring. The factor ring $\widetilde{R}\_{\clubsuit} \equiv R\_{\clubsuit}/ {\cal J}\_{\clubsuit}$ is isomorphic to GF(2) $\otimes$ GF(2). The projective line over $\widetilde{R}\_{\clubsuit}$ features nine points, each of them being surrounded by four neighbour and the same number of distant points, and any two distant points share two neighbours. These remarkable ring geometries are surmised to be of relevance for modelling entangled qubit states, to be discussed in detail in Part II of the paper.Comment: 8 pages, 2 figure

FAKTOR-FAKTOR YANG BERHUBUNGAN DENGAN PENGAMBILAN KEPUTUSAN MEMILIH PENOLONG PERSALINAN PADA IBU HAMIL DI WILAYAH KERJA PUSKESMAS LHOKNGA ACEH BESAR

Derajat kesehatan ibu dapat dinilai salah satunya dengan angka kematian ibu. Angka kematian ibu adalah kematian wanita yang terjadi selama masa kehamilan sampai dengan 42 hari setelah berakhirnya kehamilan. Angka kematian ibu bisa dipicu oleh penanganan persalinan yang dilakukan oleh penolong persalinan. Oleh sebab itu, ibu hamil harus memilih penolong persalinan yang tepat demi mencegah kematian ibu. Tujuan penelitian ini adalah mengetahui faktor-faktor yang berhubungan dengan pengambilan keputusan memilih penolong persalinan pada ibu hamil di wilayah kerja Puskesmas Lhoknga Aceh Besar tahun 2014. Jenis penelitian deskriptif korelatif dengan desain cross sectional study. Jumlah populasi 367 orang, pengambilan sampel dengan metode stratified random sampling pada 86 orang responden. Pengumpulan data dilakukan pada tanggal 3 Februari 2014 dengan menggunakan kuesioner berupa 51 pernyataan dalam bentuk dikotomi dan check list. Metode analisis data menggunakan uji Chi-Square. Hasil penelitian: tidak ada hubungan antara sosial budaya dengan pengambilan keputusan memilih penolong persalinan di wilayah kerja Puskesmas Lhoknga Aceh Besar tahun 2014 (p-value 0,437), pengetahuan (p-value 1,000), dukungan keluarga (p-value 0,699) dan fasilitas pelayanan kesehatan (p-value 0,236), namun ada hubungan sikap dengan pengambilan keputusan memilih penolong persalinan (p-value 0,055). Disarankan kepada ibu hamil agar dapat mencari informasi mengenai persalinan sehingga dapat memilih tindakan tepat terkait persalinan agar keselamatan serta kesehatan ibu dan bayi terjamin.Banda Ace

A multiple objective test assembly approach for exposure control problems in computerized adaptive testing

Overexposure and underexposure of items in the bank are serious problems in operational computerized adaptive testing (CAT) systems. These exposure problems might result in item compromise, or point at a waste of investments. The exposure control problem can be viewed as a test assembly problem with multiple objectives. Information in the test has to be maximized, item compromise has to be minimized, and pool usage has to be optimized. In this paper, a multiple objectives method is developed to deal with both types of exposure problems. In this method, exposure control parameters based on observed exposure rates are implemented as weights for the information in the item selection procedure. The method does not need time consuming simulation studies, and it can be implemented conditional on ability level. The method is compared with Sympson Hetter method for exposure control, with the Progressive method and with alphastratified testing. The results show that the method is successful in dealing with both kinds of exposure problems

Effect van varkensvleesmeel in vleeskuikenvoer op technische resultaten, slachtrendementen, strooiselkwaliteit, voetzoollaesies en darmgezondheid = Effect of pork meat meal in broiler diets on performance, slaughter yields, litter quality, foot pad dermatitis and gut health

Wageningen UR Livestock Research has conducted an experiment to determine the effect of inclusion of graded levels of pork meat meal (PMM) in broiler diets on performance, processing yields, litter quality, foot pad lesions and gut health. Inclusion of PMM in broiler diets corresponding to 10% of the basal dietary CP content did not affect performance, whereas higher inclusion levels adversely affect performance and external quality

Inventory Existing Risk Scenarios

This report provides an inventory of existing hazard data, spatial data sets and socioeconomic projections to process scenario information and future risk projections for the ENHANCE case studies. As a basis for this inventory, we conducted a small survey across the EHNHANCE cases study on their data needs. Table 1.1 provides a preliminary overview of the hazard- and socioeconomic data and scenario's required within the different case studies. This overview on the case study data needs and the data availability within the different case study partners, was discussed during the project meetings in Venice, May 2013 and Ispra (September 2013). During the meeting in Ispra, the case studies were offered a 2 days hands on workshop on how to use scenario and risk data or their case studies. This workshop was offered by IVM and JRC. Since the ENHANCE project follows a risk based approach, we similarly have focused this report on (1) data and projections for different types of natural hazards (Chapter 2) and (2) trends in socioeconomic factors that influence exposure and vulnerability to the natural hazard (Chapter 3). In addition, we have specifically outlined methods to process socioeconomic scenarios (Chapter 4) and probabilistic methods (Chapter 5) to describe extreme events with a very low probability. The main objectives of this report are to: - Provide an inventory of dynamic hazard scenarios at the pan-European scale, based on existing information at JRC or other institutes; - Provide an inventory of socioeconomic data and projections in Europe as well as some global outlook projections, possibly relevant for ENHANCE; - Develop a probabilistic risk framework for identifying probabilities of extreme events in the case studies

Effect strooiselmateriaal, strooiselhoeveelheid, opvangschoteltjes en waterdruk op resultaten vleeskuikens = Influence of bedding material, bedding amount, drip cup and reduced water pressure on broiler performance

Four different bedding materials for broiler houses were compared: white wood shavings, chopped wheat straw, ground rapeseed straw and silage maize. Performance results, carcass yields, litter quality, broiler quality and gait score were measured
