Neural Networks Architecture Evaluation in a Quantum Computer

In this work, we propose a quantum algorithm to evaluate neural networks architectures named Quantum Neural Network Architecture Evaluation (QNNAE). The proposed algorithm is based on a quantum associative memory and the learning algorithm for artificial neural networks. Unlike conventional algorithms for evaluating neural network architectures, QNNAE does not depend on initialization of weights. The proposed algorithm has a binary output and results in 0 with probability proportional to the performance of the network. And its computational cost is equal to the computational cost to train a neural network

Drifting diffusion on a circle as continuous limit of a multiurn Ehrenfest model

We study the continuous limit of a multibox Erhenfest urn model proposed before by the authors. The evolution of the resulting continuous system is governed by a differential equation, which describes a diffusion process on a circle with a nonzero drifting velocity. The short time behavior of this diffusion process is obtained directly by solving the equation, while the long time behavior is derived using the Poisson summation formula. They reproduce the previous results in the large $M$ (number of boxes) limit. We also discuss the connection between this diffusion equation and the Schr$\ddot{\rm o}$dinger equation of some quantum mechanical problems.Comment: 4 pages prevtex4 file, 1 eps figur

Lumped-Parameter Model and Nonlinear DSSI Analysis

A 2-.degrees-of-freedom discrete model with 8 constant lumped parameters is developed to equivalently simulate frequency-dependent dynamic impedances of the elastic halfspace. The equations of motion for the nonlinear dynamic soil-structure interaction (DSSI) analysis are established in the time domain and then nonlinear seismic responses of the coupling system are predicted by the proposed iterative procedure. Based on numerical results for three typical shear-type structures, effects of the shear stiffness of underlying soils and different ground motions on dynamic responses are examined

Early hospital readmissions post‐kidney transplantation are associated with inferior clinical outcomes

Unplanned hospital readmissions are common early post‐kidney transplantation. We investigated the relationship between early hospital readmissions and clinical outcomes in a single‐center retrospective study that included all adult kidney transplant patients between 2004 and 2008 with follow‐up to December 2012. The early hospital readmissions within the first 30 d were numbered and the diagnosis ascertained. Patients were grouped as none, once, and twice or more readmissions. Predictors of early readmissions were assessed, and clinical outcomes and patient and death‐censored kidney survival were compared. Among 1064 patients, 203 (19.1%) patients had once and 83 (7.8%) patients had twice or more readmissions within 30 d. Surgical complications, infections, and acute kidney injuries/acute rejection were three most common diagnoses. The length of initial hospital stay and African American race were among the variables associated significantly with readmissions. Patients with early readmissions had lower baseline renal function (p < 0.01) and more early acute rejection (p < 0.01). During follow‐up, only frequent readmissions, twice or more, within 30 d were associated with increased risk of death ( AHR 1.75, p   =   0.01) and death‐censored kidney failure ( AHR 2.20, p < 0.01). Frequent early hospital readmissions post‐transplantation identify patients at risk for poor long‐term outcomes, and more studies are needed to understand the mechanisms.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/106830/1/ctr12347.pd

Effects of Dehydration on Freezing Characteristics and Survival in Liquid Nitrogen of Three Recalcitrant Seeds

The recalcitrant seeds rambutan( Nephelium lappaceum). durian (Durio zibethinus) and cempedak (Artocarpus inleger) have a high critical moisture content (below which ·rapid loss of viability occurs of 27.0%, 26.0% and 37.9%,respectively. The critical moisture for embroys were higher at 39.0% for rambutan, 53.9% for durian and 43.2% for Cempedak. Differential Thermal analysis of the embroyos confirmed that their threshhold moistures (below which there is no freezable water) were lower than their critical moistureS. The Threshhold moistures for rambutan, durian and cempedak embryos were approximately 30%, 32% and 33% respectively. It is suggested that unsuccessful attempts at cryopreservation of embroyos of 'recalcitrant seeds in the past maybe due to the absence of safe window between the high critical moisture content and the threshhold moisture. This results in freezing injury at the higher moistures and dehydration injury' at the lower moistures. Potential techniques to overcome this and improve cryopreservation of recalcitrant seed embryos are discussed

Invariant tori and boundedness of solutions of non-smooth oscillators with Lebesgue integrable forcing term

Since Littlewood works in the 1960's, the boundedness of solutions of Duffing-type equations $\ddot{x}+g(x)=p(t)$ has been extensively investigated. More recently, some researches have focused on the family of non-smooth forced oscillators $\ddot{x}+\text{sgn}(x)=p(t)$, mainly because it represents a simple limit scenario of Duffing-type equations for when $g$ is bounded. Here, we provide a simple proof for the boundedness of solutions of the non-smooth forced oscillator in the case that the forcing term $p(t)$ is a $T$-periodic Lebesgue integrable function with vanishing average. We reach this result by constructing a sequence of invariant tori whose union of their interiors covers all the $(t,x,\dot x)$-space, $(t,x,\dot{x})\in \mathbb{S}^1\times\mathbb{R}^2$

Desiccation and Cryopreservation of Embryonic Axes of Hevea brasiliensis Muell. - Arg.

Hevea embryonic axes were desiccated for a period of 1 - 5 hours and the moisture content was determined at the end of each hour of desiccation. Another set of embryonic axes were aseptically desiccated for the same period before they were cryopreserved for 16 hours by direct immersion in liquid nitrogen (-196°C). At a moisture content between 14 - 20% (desiccation for 2 - 5 hours), 20 - 69% of the embryonic axes survived cryopreservation and formed seedlings with normal roots and shoots when cultured in vitro. A bnormalities were deteched in some seedlings however, hence, refinement of the technique is needed

Profil Glukosa dan Urea Darah Sapi Bali Jantan yang digemukkan dengan Pakan Komplit yang Mengandung Level Protein Kasar berbeda

The purpose of this study was to determine the glucose and urea profile of Bali bovine blood fattened with complete feed containing different levels of crude protein (PK). Cattle used by male Bali cattle are 2 - 2.5 years old with an initial weight of 200 kg. The rations used in the manufacture of complete feed are prepared with feed ingredients such as: natural grass, gliricida sepium, rice bran, corn flour, pollard bran. The variables measured in the study were blood glucose and blood urea of male Bali cattle. The method used is an experimental method using a completely randomized design (CRD) with the following treatment: T1: 27% Natural Grass + Gliricida sepium 10% + Corn Flour 34% + Pollard 15% + Rice Bran 14% T2: Natural Grass 27% + 20% Gliricida Sepium + 18% Corn Flour + 15% Pollard + 10% Rice Bran T3: 27% Natural Grass + 13% gliricida sepium + 20% Corn Flour + 15% Pollard + 7% Rice Bran The results of this study indicate that, the use of complete feed with different PK levels does not affect the glucose and urea levels of blood of Bali bulls (P&gt; 0.05). Where the blood glucose level for each treatment is, T1: 92,392 ± 9,779, T2: 87,448 ± 7,905 T3: 93,717 ± 14,969 while the blood urea levels for each treatment are T1: 44,629 ± 5,663, T2: 45,473 ± 4,152, T3: 44,543 ± 8,343. Based on description of the results of the research that has been done, it can be concluded that the provision of complete feed with PK level (11%, 13%, 15%) at 72% TDN has the same effect for all treatments and produces blood glucose and urea levels in the normal range.Tujuan dari penelitian ini adalah untuk mengetahui profil glukosa dan urea darah sapi bali jantan yang digemukkan dengan pakan komplit yang mengandung level protein kasar (PK) berbeda.
