Analiza maksimalnih procijepa pseudorapiditeta u nuklearnim sudarima na par do nekoliko stotina gev

This paper presents new results on the maximum gap (∆max) in the pseudorapidity distribution of charged particles in individual events in 24Mg-AgBr, 16O-AgBr and 32S-AgBr interaction in the energy range 4.5 − 200 AGeV. The location of the ∆max in an event and the experimental ∆max distribution at all energies has been studied in details. It has been observed that Gaussian distribution can describe the experimental data satisfactorily over the entire energy range.Predstavljamo nove ishode mjerenja maksimalnih procijepa (∆_max) u raspodjeli pseudorapiditeta nabijenih čestica u pojedinačnim sudarima 24Mg-AgBr, 16O-AgBr i 32S-AgBr na energijama 4.5−200 AGeV. Podrobno smo odredili položaje (∆_max) za pojedine sudare i proučili njihovu eksperimentalnu raspodjelu na tim energijama. Opažamo da Gaussova raspodjela može dobro opisati eksperimentalne podatke u cijelom području energija

Kliničko-biokemijske promjene u bivola hranjenih samo suhom krmom.

The clinical signs of inappetance, poor body condition, pityriasis and decubital skin lesions in 22 stall-fed buffaloes of 18 to 20 months of age warranted the present clinical investigation. The animals were clinically examined and history was collected on feeding and management conditions. The animals had been held on wheat straw based diet supplemented with 0.5 to 0.8 kg concentrate (devoid of vitamin premix) without access to green forage for the last seven months. Six animals had skin sloughing, rough coat, abrasion and two buffaloes were on sternal recumbency and were unable to get up. Blood samples were collected by jugular venepuncture from eight randomly selected from the 22 affected buffaloes, with varying degrees of clinical signs, and from five control buffaloes of a similar age group, who were provided with ad lib green fodder to serve as control. Serum samples were analyzed for blood glucose, total protein, albumin, urea, uric acid, creatinine, calcium, and phosphorous. Aspartate animo-transferase (AST) and alanine amino-transferase (ALT) activities were significantly (P<0.01) lower in serum from affected animals, indicating reduced hepatic function. Alkaline phosphatase activities (AP), along with serum cholesterol level were also significantly (P<0.05) lower in zero-green fed animals compared to the controls. Blood copper and zinc concentrations were statistically comparable in both the groups, but the mean values for cobalt and iron were significantly lower in affected animals. Mean plasma level of vitamin A, ß-carotene and α-tocopherol was significantly (P<0.01) lower in affected animals than in the controls. This is the first report documenting the combined deficiency of vitamin A and its precursor ß- carotene along with α-tocopherol, and the affected animals had reduced hepatic function. The present investigation strongly suggests provision of green fodder or supplementation of vitamins in the diet of buffaloes to avoid poor health and clinical signs associated with deficiency.U 22 stajski hranjena bivola, čija se dob kretala između 18 do 20 mjeseci, zabilježeni su klinički znakovi gubitka apetita, opadanja kondicije, te suhog ljuštenja i dekubitalnih oštećenja kože. Životinje su klinički pregledane i prikupljeni su podatci vezani za hranidbu i uvjete držanja. Osnovu obroka činila je pšenična slama kojoj je dodavano od 0,5 do 0,8 kg koncentrata (bez vitaminskoga premiksa). Bivolima je uskraćena mogućnost pristupa svježoj zelenoj krmi tijekom posljednjih sedam mjeseci. Šest životinja imalo je grubu kožu s pojavama ljuštenja i guljenja, a u dva bivola utvrđeno je ležanje na prsima s nemogućnošću ustajanja. Uzorci krvi iz jugularne vene prikupljeni su od 8 slučajno odabranih bivola zahvaćenih različitim stupnjem kliničkih promjena, te od 5 bivola koji su bili u približno istoj dobi i poslužili su kao kontrolna skupina hranjena svježom zelenom krmom po volji. U uzorcima seruma analizirani su glukoza, ukupni protein, albumin, mokraćevina, mokraćna kiselina, kreatinin, kalcij i fosfor. Aktivnosti aspartat amino-transferaze (AST) i alanin amino-transferaze (ALT) bile su značajno (P<0,01) niže u serumu životinja sa zahvaćenim promjenama što upućuje na smanjenu funkciju jetara. Aktivnost alkalne fosfataze (AP), zajedno s razinom serumskog kolesterola, bila je također značajno (P<0,05) snižena u životinja hranjenih suhom krmom u usporedbi sa životinjama kontrolne skupine. Koncentracije bakra i cinka u krvi bivola obje skupine bile su slične, a srednje vrijednosti za kobalt i željezo bile su značajno snižene u životinja zahvaćenih promjenama. Srednja razina vitamina A, β-karotena i α-tokoferola bila je značajno (P<0,01) niža u životinja zahvaćenih promjenama u odnosu na životinje u kontrolnoj skupini. Ovo je prvo izvješće koje potvrđuje da udruženi nedostatak vitamina A i njegova prekusora β-karotena, zajedno s nedostatkom α-tokoferola, u životinja zahvaćenih promjenama dovode do smanjene funkcije jetara. Kako bi se izbjeglo slabljenje zdravlja i pojave kliničkih znakova povezanih s navedenim deficijencijama, predlaže se u krmni obrok bivola dodavati svježu zelenu krmu ili vitamine

Integrated Loop Optimizations for Data Locality Enhancement of Tensor Contraction Expressions †‡

A very challenging issue for optimizing compilers is the phase ordering problem: In what order should a collection of compiler optimizations be performed? We address this problem in the context of optimizing a sequence of tensor contractions. The pertinent loop transformations are loop permutation, tiling, and fusion; in addition, the placement of disk I/O statements crucially affects performance. The space of possible combinations is exponentially large. We develop novel pruning strategies whereby a search problem in a larger space is replaced by a large number of searches in a much smaller space, to determine the optimal permutation, fusion, tiling and placement of disk I/O statements. Experimental results show that we obtain an improvement in I/O cost by a factor of up to 2.6 over an equi-tile-size approach. 1
