description: A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate alternative management interventions. Data were collected from the Food Animal Health Resource Management System (FAHRMX), Today's Electronic Planning (TELPLAN), Today's Electric Farm Accounting (TELF ARM) databases and secondary sources at Michigan State University. A case study of cystic ovaries was analysed using the model. The results showed that it is more economical to treat cystic ovaries than not to treat, and treatment with Gonadotropin Releasing Hormone (GNRH) was superior to Human Chrionic Gonadotropin (HCG). Four to five lactations were the optimum for keeping a dairy cow to replacement and it was estimated that there is a loss of US$0.45 per day of extended calving interval (days open beyond the optimal 70 days).

description: We study the force-induced unfolding of a homopolymer on the three dimensional Sierpinski gasket. The polymer is subject to a contact energy between nearest neighbour sites not consecutive along the chain and to a stretching force. The hierarchical nature of the lattice we consider allows for an exact treatment which yields the phase diagram and the critical behaviour. We show that for this model mean field predictions are not correct, in particular in the exact phase diagram there is {\em not} a low temperature reentrance and we find that the force induced unfolding transition below the theta temperature is second order.

description: We study an antiferromagnetic spin-1/2 model with up to third nearest-neighbor couplings on the Kagome lattice in the easy-axis limit, and show that its low-energy dynamics are governed by a four site XY ring exchange Hamiltonian. Simple ``vortex pairing'' arguments suggest that the model sustains a novel fractionalized phase, which we confirm by exactly solving a modification of the Hamiltonian including a further four-site interaction. In this limit, the system is a featureless ``spin liquid'', with gaps to all excitations, in particular: deconfined S^z=1/2 bosonic ``spinons'' and Ising vortices or ``visons''. We use an Ising duality transformation to express vison correlators as non-local strings in terms of the spin operators, and calculate the string correlators using the ground state wavefunction of the modified Hamiltonian. Remarkably, this wavefunction is exactly given by a kind of Gutzwiller projection of an XY ferromagnet. Finally, we show that the deconfined spin liquid state persists over a finite range as the additional four-spin interaction is reduced, and study the effect of this reduction on the dynamics of spinons and visons.

description: Distributed machine learning is an approach allowing different parties to learn a model over all data sets without disclosing their own data. In this paper, we propose a weighted distributed differential privacy (WD-DP) empirical risk minimization (ERM) method to train a model in distributed setting, considering different weights of different clients. We guarantee differential privacy by gradient perturbation, adding Gaussian noise, and advance the state-of-the-art on gradient perturbation method in distributed setting. By detailed theoretical analysis, we show that in distributed setting, the noise bound and the excess empirical risk bound can be improved by considering different weights held by multiple parties. Moreover, considering that the constraint of convex loss function in ERM is not easy to achieve in some situations, we generalize our method to non-convex loss functions which satisfy Polyak-Lojasiewicz condition. Experiments on real data sets show that our method is more reliable and we improve the performance of distributed differential privacy ERM, especially in the case that data scale on different clients is uneven.
I teatri anatomici dell’Università di Pisa

description: Questo articolo prosegue le pubblicazioni della sezione della nuova rivista della Società Italiana di Storia della Medicina dedicata al progetto THesa (THeatre Science Anatomy), che mira alla catalogazione, alla riscoperta e alla rivalutazione dei teatri anatomici storici, sorti tra il Medioevo e la prima metà del Novecento. In accordo con lo spirito del progetto, questo articolo è dedicato ai teatri anatomici dell’Università di Pisa. La lunga tradizione degli studi anatomici pisani iniziò con la presenza a Pisa, su invito di Cosimo I de’ Medici, del celebre anatomista Andrea Vesalio (1514-1564), considerato il padre dell’anatomia moderna e autore del De Humani corporis fabrica, un’opera che rivoluzionò l’approccio allo studio del corpo umano. È proprio con la presenza di Vesalio che si ha la prima documentazione di un teatro anatomico universitario. Con lo sviluppo della chirurgia e l’aumento degli studenti, alla fine del Settecento il teatro fu spostato presso l’ospedale, subendo nel tempo molti rimaneggiamenti e restauri. Risultato poi inadeguato, ne fu allestito uno nuovo nella Scuola Medica, costruita nel 1874. Purtroppo nessun teatro anatomico pisano è sopravvissuto fino ai giorni nostri.

description: We use molecular dynamics computer simulations to study the relaxation dynamics of Na2O-2(SiO2) in its molten, highly viscous state. We find that at low temperatures the incoherent intermediate scattering function for Na relaxes about 100 times faster than the one of the Si and O atoms. In contrast to this all coherent functions relax on the same time scale if the wave-vector is around 1AA^-1. This anomalous relaxation dynamics is traced back to the channel-like structure for the Na atoms that have been found for this system. We find that the relaxation dynamics for Si and O as well as the time dependence of the coherent functions for Na can be rationalized well by means of mode-coupling theory. In particular we show that the diffusion constants as well as the alpha-relaxation times follow the power-law predicted by the theory and that in the beta-relaxation regime the correlators obey the factorization property with a master curve that is described well by a von Schweidler-law. The value of the von Schweidler exponent $b$ is compatible with the one found for the mentioned power-law of the relaxation times/diffusion constants. Finally we study the wave-vector dependence of f_s(q) and f(q), the coherent and incoherent non-ergodicity parameters. For the Si and O atoms these functions look qualitatively similar to the ones found in simple liquids or pure silica, in that the coherent function oscillates (in phase with the static structure factor) around the incoherent one and in that the latter is approximated well by a Gaussian function. In contrast to this, f(q) for Na-Na is always smaller than f_s(q) for Na and the latter can be approximated by a Gaussian only for relatively large q.

description: Ions of the isomer $^{229m}$Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They can be efficiently captured in Paul traps which are ideal for performing high precision quantum logic spectroscopy. Trapping and identification of long-lived $^{232}$Th$^{+}$ ions from a laser ablation source was already demonstrated by the TACTICa collaboration on Trapping And Cooling of Thorium Ions with Calcium. The $^{229m}$Th is most easily accessible as $α$-decay daughter of the decay of $^{233}$U. We report on the development of a source for slow Th ions, including $^{229(m)}$Th for the TACTICa experiment. The $^{229(m)}$Th source is currently under construction and comprises a $^{233}$U monolayer, from which $^{229(m)}$Th ions recoil. These are decelerated in an electric field. Conservation of the full initial charge state distribution of the $^{229(m)}$Th recoil ions is one of the unique features of this source. We present ion-flight simulations for our adopted layout and give a final design. This source will provide Th ions in their original charge state at energies suitable for capture in a linear Paul trap for spectroscopy investigations.

description: The objective of this study is to determine if there are important size and industry effects on financial performance of agricultural cooperatives. The performance of 43 dairy, food, grain, and farm supply cooperatives in the U.S. was analyzed over the period 1970-1987 using financial ratios derived from accounting data. The analysis revealed significant size and industry effects. Large regional cooperatives are more efficient in utilizing their assets to generate sales, while small regional cooperatives have higher profitability. The findings suggest that the emphasis on growth may not always produce beneficial results among agricultural cooperatives. Among the four industries studied, the dairy regional cooperatives appear to be the strongest performers, while the food marketing cooperatives are characterized by the lowest performance measures. Since both dairy and food cooperatives engage in value-added processing, this difference in performance makes it difficult to reach clear conclusions about possible advantages of disadvantages or vertical integration relative to traditional cooperative activities. Trend analysis indicates that the profitability of the agricultural cooperatives in all industry and size categories declined in response to the downturn in U.S. agriculture after 1980. While the decline in profitability was at similar rates for both large and small cooperatives, the variation of efficiency and leverage was in opposite directions. Large cooperatives may be expected to continue improving their asset utilization without relative improvement in profitability, and increasing the level of their debt in relation to equity.

Risk and Uncertainty

description: A risk management model based on portfolio theory which accounts jointly for price, quantity, interest rate and exchange rate risks is developed and applied to cocoa and coffee production and exports in the Ivory Coast. Utilizing commodity and financial futures markets jointly, the results show that a government export agency can reduce risks from 27% to 89% by following a multicommodity hedging program which manages several risks simultaneously. The model and technique developed are applicable to many multiproduct firm and international risk management situations.

description: Hartree-Fock theory predicted stripe or bubble phase in the third and higher Landau levels for two-dimensional electrons, and experimental evidences has been accumulated. In this paper theoretical confirmation of the stripe phase and bubble phase in higher Landau level is given by means of the density matrix renormalization group (DMRG) method, which can give essentially exact ground state for electron systems with up to 18 electrons. From the study of the pair correlation function, the stripe phase, bubble phase, and the Wigner crystal phase are identified, and phase diagram is obtained. The reentrant integer quantum Hall state is identified as the bubble state. The phase diagram of the fourth Landau level shows more diversity than the third level.

description: Nella Palermo di fine secolo XIX sorse una libera società di volontariato per la protezione sia degli animali sia dell’infanzia, assumendo denominazione e finalità del tutto uniche in Italia, giacché gli altri enti analoghi avevano per scopo soltanto la protezione degli animali. In Sicilia gli animali di utilità erano regolarmente maltrattati e sottoposti a un lavoro superiore alle loro concrete possibilità fisiche; e allo sfruttamento non sfuggivano neppure i bambini di età compresa tra i 6 e i 12 anni, sottoposti a estenuanti fatiche nelle miniere di zolfo e in altre fabbriche e opifici, con un sovrannumero di ore in interminabili giornate lavorative. La Società sviluppò tre ambiti di intervento: la protezione degli animali, la tutela dell’infanzia abbandonata, l’impegno educativo nelle scuole. Ricevette numerosi contributi per il funzionamento e fu anche premiata dal Ministro dell’Istruzione Guido Baccelli. È una interessante storia di sofferenza ed esempio di riscatto morale e sociale, di cui furono protagonisti la scuola e tanti liberi cittadini siciliani.

description: We report on three launches of ballooning $Erigone$ spiders observed in a 0.9 m$^3$ laboratory chamber, controlled under conditions where no significant air motion was possible. These launches were elicited by vertical, downward-oriented electric fields within the chamber, and the motions indicate clearly that negative electric charge on the ballooning silk, subject to the Coulomb force, produced the lift observed in each launch. We estimate the total charge required under plausible assumptions, and find that at least 1.15 nC is necessary in each case. The charge is likely to be non-uniformly distributed, favoring initial longitudinal mobility of electrons along the fresh silk during extrusion. These results demonstrate for the first time that spiders are able to utilize charge on their silk to attain electrostatic flight even in the absence of any aerodynamic lift.

description: Reduced-form price spread models have been recently utilized by Wohlgenant and Mullen, and Thompson and Lyon to evaluate the economic factors affecting the marketing margins for agricultural products. Drawing on Gardner, Heien, Buse and Brandow, Waugh, Tomek and Robinson, and others they specify alternative retail-farm price spread models and attempt to determine which best fit the data in the context of underlying theoretical rationale. This paper continues in the spirit of Wohlgenant and Mullen, and Thompson and Lyon by evaluating alternative specifications of the retail-farm price spread for white maize in South Africa. However, several important differences do remain. Wohlgenant and Mullen analyzed the price spread for beef using annual data, while Thompson and Lyon modeled the price spread for oranges using weekly data. The time period under consideration can be expected to affect the choice of model because fixed markup rules that might be evident using a short-run period of analysis (e.g., Thompson and Lyon) become untenable over the long run with underlying supply and demand shifts. In this paper, monthly data, which may be interpreted as an intermediate-run period, are used along with dichotomous supply-demand shifters. In addition, Brorsen et. a!. have shown that price uncertainty affects the price spread in the marketing channels of agricultural commodities. Thus, the analysis in this paper extends the framework of Wohlgenant and Mullen, and Thompson and Lyon to include measures of price risk. Finally, like Brorsen et. a!. this study pertains to the grain market, while Wohlgenant and Mullen, and Thompson and Lyon studied the marketing margin for non-storable commodities.

Это связано, прежде всего, со снижением трудозатрат при выполнении одних операций и, в тоже время, с увеличением трудоемкости работ на других операциях, а также возникновением новых задач. Все больше требований предъявляется к менеджменту организации, который направлен на выполнение одновременно многих задач, расстановку приоритетов и проявление инициативы, ответственности за принимаемые решения. Комплекс этих требований способствует возникновению признаков профессионального стресса, с которым сотрудник не всегда может справиться. Для многих корпоративных систем управления здоровьем в организациях, наступил период переоценки системы работы и выработки новых решений. Существуют исследования, которые определяют эффективность программ корпоративного сектора, которые направлены на укрепление и профилактику здоровья сотрудников организаций. В статье описаны и проанализированы существующие подходы к здоровьесбережению в HR менеджменте и сделаны выводы о возможностях и перспективах реализации данных подходов в условиях пандемии.

description: Rice is the most important staple food in the People's Republic of China (PRC). In many Asian countries rice appears to have become an inferior good, with income increases leading to declines in per capita consumption as other food products are substituted for rice. In this study, human rice consumption is analyzed with a model that allows income elasticities to vary with income levels. An additional equation accounting for rice disappearance as seed, livestock feed, industrial uses and exports is also estimated. The results of the analysis indicate that rice has become an inferior good in China and per capita consumption is likely to decline in the future. Population growth and the growing use of rice for other purposes means that total rice disappearance will continue to increase although at a rate that is slower than has historically been the case. The predicted changes in rice consumption will create pressures to adjust production and trade patterns for rice as well as other agricultural products.

description: We consider the hyperfine-mediated transition rate between Zeeman split spin states of the lowest orbital level in a GaAs quantum dot. We separate the hyperfine Hamiltonian into a part which is diagonal in the orbital states and another one which mixes different orbitals. The diagonal part gives rise to an effective (internal) magnetic field which, in addition to an external magnetic field, determines the Zeeman splitting. Spin-flip transitions in the dots are induced by the orbital mixing part accompanied by an emission of a phonon. We evaluate the rate for different regimes of applied magnetic field and temperature. The rates we find are bigger that the spin-orbit related rates provided the external magnetic field is sufficiently low.

Vortices and composite order in $\mathrm{SU}(N)$ theories coupled to Abelian gauge field

description: We consider $\mathrm{SU}(N)$-symmetric Ginzburg-Landau models coupled to non-compact Abelian gauge field focusing on the case $N > 2$ at finite temperature. We show that, at least for sufficiently large gauge-field coupling constants, these models have two phase transitions. The intermediate phase between the symmetric and low-temperature phases is a state with composite neutral order and no Meissner effect. In this neutral phase the system spontaneously breaks only the symmetry associated with phase differences and density differences between components. For $N > 2$, in contrast to the $SU(2)$ case, the neutral state cannot be mapped onto an $\mathrm{O}(M)$ model. We term this state ${\mathbb{C}{P}}^{N-1}$-neutral phase. We also show that while $\mathrm{SU}(N)$-symmetric Ginzburg-Landau models are not superconductors or superfluids in the usual sense, their state in external field at sufficiently low temperature is a vortex lattice.

description: We present results from JCMT sub-mm observations of sources selected from the {\sl ISO} FIRBACK (Far-IR BACKground) survey, along with UKIRT near-IR imaging of a sub-sample. This gives valuable insight into the brightest $\sim$10% of galaxies which contribute to the Cosmic Infrared Background (CIB). We estimate the photometric redshifts and luminosities of these sources by fitting their Spectral Energy Distributions (SEDs). The data appear to show a bimodal galaxy distribution, with normal star-forming galaxies at $z\simeq0$, and a much more luminous population at $z\sim0.4$--0.9. These are similar to the ultraluminous infrared galaxies which are found to evolve rapidly with redshift in other surveys. The detectability threshold of FIRBACK biases the sample away from much higher redshift ($z\stackrel{>}{_{\sim}}1.5$) objects. Nevertheless, the handful of $z\sim0.5$ sources which we identify are likely to be the low-$z$ counterparts of the typically higher-$z$ sources found in blank field sub-mm observations. This sub-sample, being much more nearby than the average SCUBA galaxies, has the virtue of being relatively easy to study in the optical. Hence their detailed investigation could help elucidate the nature of the sub-mm bright galaxies.

description: We consider two $s=1/2$ spins with Heisenberg coupling and a monochromatic, circularly polarized magnetic field acting only onto one of the two spins. This system turns out to be analytically solvable. Also the statistical distribution of the work performed by the driving forces during one period can be obtained in closed form and the Jarzynski equation can be checked. The mean value of this work, viewed as a function of the physical parameters, exhibits features that can be related to some kind of Rabi oscillation. Moreover, when coupled to a heat bath the two spin system will approach a non-equilibrium steady state (NESS) that can be calculated in the golden rule approximation. The occupation probabilities of the NESS are shown not to be of Boltzmann type, with the exception of a single phase with infinite quasitemperature. The parameter space of the two spin Rabi model can be decomposed into eight phase domains such that the NESS probabilities possess discontinuous derivatives at the phase boundaries. The latter property is shown to hold also for more general periodically driven $N$-level systems.

description: The superconducting order parameter and electron-phonon interaction (EPI) in a MgB$_{2}$ c-axis oriented thin film are investigated by point contacts (PCs). Two superconducting gaps $Δ_{Small}\approx 2.6$ meV and $Δ_{Large}\approx 7.4$ meV have been established, which fairly well correspond to the theoretical gap ratio 1:3. The reconstructed PC EPI function along c-axis has above 30 meV similarities with the phonon DOS, while a pronounced maximum around 20 meV is resolved pointing out that the low frequency phonon mode can be of importance for pairing. We have estimated the Fermi velocity in MgB$_2$ about 5$\times 10^7$ cm/s.

description: We study Na ion diffusion and electrochemical performance of NaVO$_3$ (NVO) as anode material in Li/Na--ion batteries with the specific capacity of $\approx$350 mAhg$^{-1}$ at the current density 11~mAg$^{-1}$ after 300 cycles. Remarkably, the capacity retains $\ge$200~mAhg$^{-1}$ even after 400~cycles at 44~mAg$^{-1}$ with Coulombic efficiency $>$99\%. The deduced diffusion coefficient from galvanostatic intermittent titration technique (GITT), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measurements for NVO as anode in Li--ion battery is in the range of 10$^{-10}$--10$^{-12}$~cm$^2$s$^{-1}$. In case of Na-ion batteries, the NVO electrode exhibits initial capacity of 385~mAhg$^{-1}$ at 7~mAg$^{-1}$ current rate, but the capacity degradation is relatively faster in subsequent cycles. We find the diffusion coefficient of NVO--Na cells similar to that of NVO--Li. On the other hand, our charge discharge measurements suggest that the overall performance of NVO anode is better in Li--ion battery than Na-ion. Moreover, we use the density functional theory to simulate the energetics of Na vacancy formation in the bulk of the NVO structure, which is found to be 0.88~eV higher than that of the most stable (100) surface. Thus, the Na ion incorporation at the surface of the electrode material is more facile compared to the bulk.

description: The equation of state of two-dimensional $^3$He at zero temperature has been calculated using the diffusion Monte Carlo method. By means of a combination of the fixed-node and released-node techniques it is shown that backflow correlations provide a very accurate equation of state. The results prove unambiguously the non-self-bound character of two-dimensional $^3$He due to its Fermi statistics. We present solid evidence that the gas phase, predicted for the two-dimensional system, can be extrapolated to the case of $^3$He adsorbed on a strong substrate like graphite.

description: Measurements destroy entanglement. Building on ideas used to study `quantum disentangled liquids', we explore the use of this effect to characterize states of matter. We focus on systems with multiple components, such as charge and spin in a Hubbard model, or local moments and conduction electrons in a Kondo lattice model. In such systems, measurements of (a subset of) one of the components can leave behind a quantum state of the other that is easy to understand, for example in terms of scaling of entanglement entropy of subregions. We bound the outcome of this protocol, for any choice of measurement, in terms of more standard information-theoretic quantities. We apply this quantum disentangling protocol to several problems of physical interest, including gapless topological phases, heavy fermions, and scar states in Hubbard model.

description: The reduction of the amplitude of Aharonov-Bohm oscillations in a ballistic one-channel mesoscopic interferometer due to charge fluctuations is investigated. In the arrangement considered the interferometer has four terminals and is coupled to macroscopic metallic side-gates. The Aharonov-Bohm oscillation amplitude is calculated as a function of temperature and the strength of coupling between the ring and the side-gates. The resulting dephasing rate is linear in temperature in agreement with recent experiments. Our derivation emphasizes the relationship between dephasing, ac-transport and charge fluctuations.
