Universitatea de Stat de MedicinÄ Ĺi Farmacie âNicolae TestemiĹŁanuâ, Spitalul Clinic Republican, Spitalul Clinic Municipal nr. 1Patologia respiratorie ĂŽn perioada peripartum implicÄ un risc major, atât pentru viaĹŁa mamei, cât Ĺi a copilului. InsuficienĹŁa pulmonarÄ acutÄ creĹte rata mortalitÄĹŁii materne ĂŽn sarcinÄ pânÄ la 90%, comparativ cu 50-60% ĂŽn afara sarcinii. Rata insuficienĹŁei pulmonare primare este micÄ comparativ cu alte patologii asociate sarcinii, constituind ĂŽn mediu 5%. Ăn marea majoritate a cazurilor ea apare secundar, ca component al insuficienĹŁei poliorganice. Modificarea fiziologiei pulmonare ĂŽn perioada peripartum necesitÄ optimizarea conduitei individuale atât ĂŽn timpul sarcinii, cât Ĺi la naĹtere. Tratamentul contemporan al insuficienĹŁei respiratorii este destul de costisitor, necesitând un monitoring sofisticat Ĺi individualizat.Respiratory pathology in pregnancy and labor involves a double risk, both for motherâs and childâs life. Acute pulmonary failure increases the rate of maternal mortality up to 90% during the pregnancy in comparison with 50-60% out of pregnancy. The incidence of pulmonary insufficiency is rather low in comparison with the other associated pregnancy pathology, established to 5%. In the most of the cases it occurs secondary as a compound of MODS. Pulmonary physiology is essentially modified in pregnancy, raising the necessity of peculiar pregnancy and labor management applied. The contemporary treatment of pulmonary insufficiency is rather expensive, requiring advanced and individualized monitoring
Amicable pairs and aliquot cycles for elliptic curves
An amicable pair for an elliptic curve E/Q is a pair of primes (p,q) of good
reduction for E satisfying #E(F_p) = q and #E(F_q) = p. In this paper we study
elliptic amicable pairs and analogously defined longer elliptic aliquot cycles.
We show that there exist elliptic curves with arbitrarily long aliqout cycles,
but that CM elliptic curves (with j not 0) have no aliqout cycles of length
greater than two. We give conjectural formulas for the frequency of amicable
pairs. For CM curves, the derivation of precise conjectural formulas involves a
detailed analysis of the values of the Grossencharacter evaluated at a prime
ideal P in End(E) having the property that #E(F_P) is prime. This is especially
intricate for the family of curves with j = 0.Comment: 53 page

Mulcirea Ĺi fertilizarea ca principal mijloc tehnologic ĂŽntr-o culturÄ organicÄ de broccoli
The purpose of the presentpaper is to evaluate the influence of mulching and fertilization on an early broccoli crop grown according to organic farming norms. The research was carried out in the experimental field of the Agronomic University of IaĹi, Romania. In the bifactorial experiment, the influence of mulching with three graduationswas tested-unmulched-Ct, mulching with polyethylene foilof 15 and 30 microns thick,as well as the fertilization with three graduations -unfertilized-Mt, organic fertilization and application of microorganisms, under the conditions of the years 2018 and 2019. The culture was established fromseedlings of42 days, in strips of 2 rows each, the distance between strips beingof80 cm and between rows of 60 cm. The distance between plants was of 25 cm,resulting in a density of about 57 thousand plants per hectare. The obtained results indicate increases inthe yield,in the case of the mulched and organicallyfertilized variants, the best yields being obtained in the case of the mulched variant with 30 microns foil and organically fertilized with Orgevi

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV
The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of âs = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pTâĽ20 GeV and pseudorapidities {pipe}Ρ{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}Ρ{pipe}<0. 8) for jets with 60â¤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2â¤{pipe}Ρ{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined.

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
The inclusive and dijet production cross-sections have been measured for jets
containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass
energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The
measurements use data corresponding to an integrated luminosity of 34 pb^-1.
The b-jets are identified using either a lifetime-based method, where secondary
decay vertices of b-hadrons in jets are reconstructed using information from
the tracking detectors, or a muon-based method where the presence of a muon is
used to identify semileptonic decays of b-hadrons inside jets. The inclusive
b-jet cross-section is measured as a function of transverse momentum in the
range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet
cross-section is measured as a function of the dijet invariant mass in the
range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets
and the angular variable chi in two dijet mass regions. The results are
compared with next-to-leading-order QCD predictions. Good agreement is observed
between the measured cross-sections and the predictions obtained using POWHEG +
Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet
cross-section. However, it does not reproduce the measured inclusive
cross-section well, particularly for central b-jets with large transverse
momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final

Predicting Outcomes of Prostate Cancer Immunotherapy by Personalized Mathematical Models
Therapeutic vaccination against disseminated prostate cancer (PCa) is partially effective in some PCa patients. We hypothesized that the efficacy of treatment will be enhanced by individualized vaccination regimens tailored by simple mathematical models.We developed a general mathematical model encompassing the basic interactions of a vaccine, immune system and PCa cells, and validated it by the results of a clinical trial testing an allogeneic PCa whole-cell vaccine. For model validation in the absence of any other pertinent marker, we used the clinically measured changes in prostate-specific antigen (PSA) levels as a correlate of tumor burden. Up to 26 PSA levels measured per patient were divided into each patient's training set and his validation set. The training set, used for model personalization, contained the patient's initial sequence of PSA levels; the validation set contained his subsequent PSA data points. Personalized models were simulated to predict changes in tumor burden and PSA levels and predictions were compared to the validation set. The model accurately predicted PSA levels over the entire measured period in 12 of the 15 vaccination-responsive patients (the coefficient of determination between the predicted and observed PSA values was R(2)â=â0.972). The model could not account for the inconsistent changes in PSA levels in 3 of the 15 responsive patients at the end of treatment. Each validated personalized model was simulated under many hypothetical immunotherapy protocols to suggest alternative vaccination regimens. Personalized regimens predicted to enhance the effects of therapy differed among the patients.Using a few initial measurements, we constructed robust patient-specific models of PCa immunotherapy, which were retrospectively validated by clinical trial results. Our results emphasize the potential value and feasibility of individualized model-suggested immunotherapy protocols
