Integrable Coupled KdV Systems
We give the conditions for a system of N- coupled Korteweg de Vries(KdV) type
of equations to be integrable. Recursion operators of each subclasses are also
given. All examples for N=2 are explicitly given.Comment: 17pp, LateX, to be published in J.Math.Phy
Multi-task Deep Neural Networks in Automated Protein Function Prediction
In recent years, deep learning algorithms have outperformed the state-of-the
art methods in several areas thanks to the efficient methods for training and
for preventing overfitting, advancement in computer hardware, the availability
of vast amount data. The high performance of multi-task deep neural networks in
drug discovery has attracted the attention to deep learning algorithms in
bioinformatics area. Here, we proposed a hierarchical multi-task deep neural
network architecture based on Gene Ontology (GO) terms as a solution to protein
function prediction problem and investigated various aspects of the proposed
architecture by performing several experiments. First, we showed that there is
a positive correlation between performance of the system and the size of
training datasets. Second, we investigated whether the level of GO terms on GO
hierarchy related to their performance. We showed that there is no relation
between the depth of GO terms on GO hierarchy and their performance. In
addition, we included all annotations to the training of a set of GO terms to
investigate whether including noisy data to the training datasets change the
performance of the system. The results showed that including less reliable
annotations in training of deep neural networks increased the performance of
the low performed GO terms, significantly. We evaluated the performance of the
system using hierarchical evaluation method. Mathews correlation coefficient
was calculated as 0.75, 0.49 and 0.63 for molecular function, biological
process and cellular component categories, respectively. We showed that deep
learning algorithms have a great potential in protein function prediction area.
We plan to further improve the DEEPred by including other types of annotations
from various biological data sources. We plan to construct DEEPred as an open
access online tool.Comment: 19 pages, 4 figures, 4 table
Gardner's deformations of the Boussinesq equations
Using the algebraic method of Gardner's deformations for completely
integrable systems, we construct the recurrence relations for densities of the
Hamiltonians for the Boussinesq and the Kaup-Boussinesq equations. By extending
the Magri schemes for these systems, we obtain new integrable equations adjoint
with respect to the initial ones and describe their Hamiltonian structures and
symmetry properties.Comment: Proc. Workshop `Quantizaion, Dualities, and Integrable Systems,'

Esterification of Acetic Acid with Butanol: Operation in a Packed Bed Reactive Distillation Column
The esterification reaction between acetic acid and butanol was investigated in a reactive distillation column. The thermodynamic aspects of considered system are discussed, equilibrium constant, vapor pressures and UNIQUAC interaction parameters were investigated. Reactive distillation experiments were carried out to provide high purity butyl acetate. For this purpose, a 2 m column with nonreactive and reactive zones filled with Amberlyst 15 and Raschig rings, were used in the experiments. Several operating conditions such as total feed flow rate, molar ratio of butanol to acetic acid, amount of catalyst and reboiler temperature and three different column configurations were realized experimentally.
The experimental optimum values of these parameters obtained were 1.6 mol h–1, 1, 25 g and 383 K, respectively within the range of study. The butyl acetate purity of 82 % and acetic acid conversion of 80.5 % were obtained at the optimum operating conditions
Maximally Random Discrete-Spin Systems with Symmetric and Asymmetric Interactions and Maximally Degenerate Ordering
Discrete-spin systems with maximally random nearest-neighbor interactions
that can be symmetric or asymmetric, ferromagnetic or antiferromagnetic,
including off-diagonal disorder, are studied, for the number of states
in dimensions. We use renormalization-group theory that is exact for
hierarchical lattices and approximate (Migdal-Kadanoff) for hypercubic
lattices. For all d>1 and all non-infinite temperatures, the system eventually
renormalizes to a random single state, thus signaling qxq degenerate ordering.
Note that this is the maximally degenerate ordering. For high-temperature
initial conditions, the system crosses over to this highly degenerate ordering
only after spending many renormalization-group iterations near the disordered
(infinite-temperature) fixed point. Thus, a temperature range of short-range
disorder in the presence of long-range order is identified, as previously seen
in underfrustrated Ising spin-glass systems. The entropy is calculated for all
temperatures, behaves similarly for ferromagnetic and antiferromagnetic
interactions, and shows a derivative maximum at the short-range disordering
temperature. With a sharp immediate contrast of infinitesimally higher
dimension 1+\epsilon, the system is as expected disordered at all temperatures
for d=1.Comment: Final published version, 4 pages, 5 figure
Readability and understandability of andrology questionnaires
Objective: Medical questionnaires, which enable collection, comparison and analysis of appropriate data as
a means of written communication between a patient and a doctor, must be easily readable, and understandable. Here, we measure the readability and understandability of questionnaires used in andrology and examine the relationship between the educational status of the patients and the understandability of the forms.
Material and methods: Seven questionnaires used to diagnose andological diseases were selected from
the European Association of Urology guidelines. The number of syllables per word, the number of words
in a sentence, and the average word and sentence lengths were calculated for each Turkish validated form.
Readability scores were calculated, and closet tests were used to measure the understandability of the texts.
Results: Three hundred and twenty-seven male volunteers participated in the study. Two hundred and sixteen of the participants (66%) had a high school or college education. The readability level of the seven
forms was determined to be ''Difficult'' or ''Very Difficult,'' and at least a high school education level was
required to understand the forms. As education level and monthly income increased, the understandability
of the forms increased; as the readability of the forms became more difficult, their understandability decreased (p<0.001).
Conclusion: The readability levels of questionnaires used in andrology are well above the reading level of
Turkey. Health providers can help patients to fill out forms to increase doctor-patient communication
