description: Cellulase represent a group of complex biocatalysts that catalyze the hydrolysis of cellulose to
 simple sugar and known for a wide gamut of applications in paper and pulp industry, winemaking and brewing, agriculture, animal feed industry, biofuel and pharmaceutical domain as
 well as in waste management. The aim of this study was to characterize some cellulase
 producing bacteria from termite (Isoptera) gut and their application in biostoning of denim cloth.
 There were eighty worker termites collected from Meki area and Zeway Central Rift Valley,
 Ethiopia of which sixteen different isolated bacterial among which six were qualitatively
 screened using Congo red as cellulase producer. Accordingly, the maximum hydrolytic capacity
 of clear zone diameter/colony diameter (were 8 and 6.25 mm value) corresponding to M21WG
 and Z6WG respectively. The highest cellulase producing bacterial isolates were characterized
 and identified initially by morphological and biochemical methods. The 16S rRNA sequences
 were analyzed and aligned using the basic local alignment search tool of the National Center for
 Biotechnology Information (NCBI) and phylogenic trees were constructed. The phylogenetic
 tree confirmed that the M21WG and Z6WG isolates were identified as Klebsiella oxytoca and
 Klebsiella sp respectively in the family Enterobacteriaceae. The maximum activity of crude
 cellulase isolated from these bacteria was monitored at optimal pH 7 to be 267 U/mL for
 Klebsiella oxytoca M21WG and 220 U/mL for Klebsiella sp Z6WG, temperature of 37 °C
 Klebsiella oxytoca M21WG 231 U/mL and Klebsiella sp Z6WG 203 U/mL, incubation time of 72
 hours 257 U/mL for Klebsiella oxytoca M21WG and 214 U/mL for Klebsiella sp Z6WG, 1.5 %
 242 U/mL Klebsiella oxytoca M21WG and 210 U/mL Klebsiella sp Z6WG of
 carboxymethylcellulose-sodium as a substrate. The maximum specific activity of crude (0.33,
 0.32 U/mg), partially purified using ammonium sulfate precipitation (7.45, 3.57 U/mg) and
 dialysis (14.12 and 13.61U/mg) of Klebsiella oxytoca M21WG and klebsiella sp Z6WG estimated
 respectively. The cellulase enzyme from Klebsiella oxytoca, M21WG and Klebsiella sp, Z6WG
 was partially purified using ammonium sulfate followed by dialysis. Subsequently, it was
 confirmed that the cellulase enzymes isolated from Klebsiella oxytoca, M21WG and Klebsiella
 sp, Z6WG were evaluated to be apply effective for biostoning of denim cloth. This work points to
 important insights into a better understanding of the characterization of some cellulase producing
 bacteria from termite (Isoptera) gut and their application in biostoning of denim cloth underlying
 the regulation of cellulolytic enzyme secretion in this termite gut bacteria

description: Euparin (1) as a natural product was derivatized by maleic anhydride (2), semicarbazide (3), phenylacetic acid (4 and 5), and thiosemicarbazide (6) and their activities were evaluated in silico by molecular docking studies to investigate the binding affinities and interaction modes between the samples and N-myristoyltransferase enzyme. Among the tested samples (1–6), compounds 1–3 showed significant hydrophobic and hydrogen bonding interactions with the important residues at the active site of the receptor. Therefore, the biological properties of compounds 1–3 were investigated in this work. The antifungal activity of compounds 1–3 was tested against Candida albicans. Amongst them, euparin 1 with minimum inhibitory concentration (MIC) of 7.81 µg/mL and minimum fungicidal concentration (MFC) of 15.62 µg/mL exhibited the highest antifungal activity. Furthermore, antibacterial activities were studied against two Gram-positive (Staphylococcus aureus and Bacillus subtilis), and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria, the highest zone of growth on B. subtilis for compound 3 was 13.5 ± 0.7 mm, while for compound 2, the zone of growth inhibition against B. subtilis and S. aureus was 10.0 ± 1.4 and 9.5 ± 0.70 mm, respectively. Finally, the anticancer effects of 1– 3 were examined using MTT assay against MDA-MB-231 and A-549 cell lines. Compound 2 displayed cytotoxicity on MDA-MB-231 cell line with IC50 of 166 µg/mL.
The magnitude of odd balls via Hankel determinants of reverse Bessel polynomials

Year: 2017
Subjects: subject: Metric Geometry (math.MG)

subject: FOS: Mathematics

description: Magnitude is an invariant of metric spaces with origins in category theory. Using potential theoretic methods, Barceló and Carbery gave an algorithm for calculating the magnitude of any odd dimensional ball in Euclidean space, and they proved that it was a rational function of the radius of the ball. In this paper an explicit formula is given for the magnitude of each odd dimensional ball in terms of a ratio of Hankel determinants of reverse Bessel polynomials. This is done by finding a distribution on the ball which solves the weight equations. Using Schröder paths and a continued fraction expansion for the generating function of the reverse Bessel polynomials, combinatorial formulae are given for the numerator and denominator of the magnitude of each odd dimensional ball. These formulae are then used to prove facts about the magnitude such as its asymptotic behaviour as the radius of the ball grows.

Subjects: subject: 140211 Labour Economics
subject: FOS: Economics and business

description: The theoretical framework by Diamond, Mortensen and Pissarides (Nobel Award in Economic Sciences, 2010) shows us how generous wages can determine the success in filling job vacancies. The empirical evidence is convincing: larger and more profitable enterprises pay higher wages. Nowadays, large leader companies are investing not only in paying efficient wages to prevent shirking, but also in the improvement of working conditions and even taking a rigorous analytical approach to etiquette. It is a common fact that small and medium-sized enterprises (SMEs) cannot compete in the same way with these high standards. However, recent examples have shown that a suitable work environment, techniques for reducing the stress factors, strategies to create workplaces with a more ethnical diversity and profound benefits for women, as well as the efforts in making the workers feel more liable to their jobs are possible in SMEs and have real benefits for their growth and productivity. At the same time, these approaches could be beneficial for developing countries in a large scale since SMEs play a major role in most of these economies. In this paper, we will conduct a study from the most popular current standards that the best companies promote and suggest some alternatives for SMEs in order to improve these factors.

description: It was planned to utilize isoniazid 1 and substituted salicylaldehydes 2a–f to synthesize some N'-[(E)-(substituted-2-hydroxyphenyl)methylidene]pyridine-4-carbohydrazides 3a–g. Compounds 3a–g on reduction with sodium borohydride in dry methanol with stirring gave N'-[(substituted-2-hydroxyphenyl) methyl] pyridine-4-carbohydrazides 4a–g in good yield. The compounds 4a–g underwent an internal Mannich reaction with formaldehyde (37%) in ethanol for 4–5 h under reflux conditions to give the desired N-(substituted-2H-1,3-benzoxazin-3(4H)-yl)pyridine-4-carboxamides 5a–g. Structures of all the newly synthesized compounds were confirmed by spectral data. All the compounds have been screened for their antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Salmonella typhi, antifungal activity against Candida albicans, Cladosporium oxysporum, Aspergillus flavus, and Aspergillus niger and anti-TB activity against M. tuberculosis. The compound 5a indicated significant inhibition against E. coli and A. flavus (MIC-6.25 µg/mL), which was found to be better than the reference drug Gentamycin and Fluconazole respectively. Further, the compound 5d showed more potent anti-TB activity (MIC-1.56 µg/mL) than the reference drug Ciprofloxacin. The DNA cleavage activity for selected compounds was also carried out by the AGE method. To understand the electronic properties of compounds 4a and 5a, DFT calculations at the DFT/B3LYP level using 6-31 G++ (d, p) have been performed to reproduce the geometry and structural features. The non-linear optical property of the compounds 4a and 5a was calculated using first-order hyperpolarisability calculation. The calculated HOMO-LUMO analysis explains the charge transfer interaction between the molecules.
Challenges Facing Local Contractors Working with Chinese Contractors in Addis Ababa Building Projects
Creators: name: Ferenj, Solomon Esaiyas
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Challenges, Local Contractors, Chinese Contractors, Subcontracting, International Building Projects

description: Building construction projects particularly represents one of the largest sectors of the
 construction industry. Currently, the rise in construction of high rising buildings are
 observed in Addis Ababa, the capital city of Ethiopia. The number and size of building
 construction projects that are being constructed in the city are increasing through time
 and most of these projects were being carried out by Chinese contractors. Local
 contractors are also involved in those projects via a subcontracting strategy. However,
 it is not easy for local contractors to succeed by working with their foreign counterparts
 who have massive international experience and capacity. The aim of this study was
 assessing and identifying the challenging factors affecting local contractors’
 performance in Chinese building projects in Addis Ababa. In order to achieve the
 objectives of this study, both quantitative and qualitative research approach were used
 with primary and secondary source of data. This study employed three types of data
 collection techniques such as a questionnaire surveys, interviews and observations. The
 target population for this study are local contractors and consultants involved in
 building projects that are carried out by Chinese contractors. In this study the researcher
 used Census/Parametric method of survey. That mean all target population of this study
 are included in this investigation, based on the consent and willingness of the
 participants. The Relative Importance Index (RII) was used as an instrument for
 analyzing data collected through questionnaire in tabular form by using Likert’s scale
 of five ordinal measures. Based on the analysis, it was found that the most challenging
 factors affecting local contractors’ performance in Chinese building projects were
 financial constraints, information exchange problems, cultural differences,
 unfamiliarity with Chinese work methodology and project complexity with a RII value
 of 0.84, 0.81, 0.77, 0.73 and 0.71 respectively. This study also identified and discussed
 the major cause and impact of those challenges and proposed measures to minimize
 their effect on the local performance in the upcoming projects through interviews from
 respondents and analyzed by using content analysis

description: We show that the CKM matrix can be the source of CP violation for electroweak baryogenesis if Yukawa couplings vary at the same time as the Higgs acquires its vacuum expectation value. This offers new avenues for explaining the baryon asymmetry of the universe. These ideas apply if the mechanism explaining the flavour structure of the Standard Model is connected to electroweak symmetry breaking. We compute the resulting baryon asymmetry for various low-scale flavour models and different configurations of the Yukawa coupling variation across the bubble wall, and show that it can naturally be of the right order.

description: The main objective of this book is the presentation of methods of finite differences for the solution of parabolic, elliptic and hyperbolic partial differential equations. The application of these methods to the solution of various practical problems is emphasized, avoiding scholastic mathematical derivations. For this reason for several fundamental methods, computer programs are presented in FORTRAN 90/95, which may be easily translated into a different computer language.

 The material of the book was developed while teaching a relative course since 1980 in the post graduate program of Agricultural Engineering and Water Resources in the Department of Hydraulics, Soil Science and Agricultural Engineering of the Aristotle University of Thessaloniki.

 For the completeness of the material of the book the first chapter is devoted to the short description of some methods of basic numerical analysis, which are necessary for the comprehension of the main material of the book. The reader of this book can find detailed description of these methods in the book of the same author titled “Numerical Analysis”.

Causes and Effects of Public Building Closeout Problems (In the Case of Addis Ababa Public Building Projects)
Creators: name: Elsabeth Abreha Abebe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Building project closeout, public building

description: The aim of this study was to assess the causes of closeout problems, their effects, identifying
 responsible parties, and suggesting controlling remedies to alleviate such related problems of
 public building projects located at Addis Ababa. The study was examined on 24 public
 building projects which were awarded by Ethiopian construction design and supervision works
 corporation building and urban design supervision works in the last ten years. Survey on these
 projects was made using document exploration and interview with professionals involved on
 those projects. Furthermore, a questionnaire was distributed for different groups such as
 employer, consultants and contractors that are role players in the public construction industry.
 The data was analyzed using mean score method.
 The findings of the study revealed that poor punch list (remark) coordination and
 execution(with a mean score 3.88), resource shortage (manpower, material and equipment)
 (with a mean score 3.75), diversion of effort to a new project (difficulty of keeping closeout a
 priority) (with a mean score 3.54), excessive and unreasonable variation order (with a mean
 score 3.63) and poor communication b/n client, consultant and contractor (with a mean score
 3.42) were identified as major causes public building closeout problems. The study further
 revealed that in most situations building closeout problems have resulted mainly in cost
 overrun (32%), time overrun (28%), quality degradation (16%), disputes (13%) and bad
 reputation (11%). The contractor was identified to be the most responsible for building
 closeout problems with 34%. Followed by the consultant by a 30%, the client by 22% and
 other factors such as force majeure, weather condition, state of emergency, problems with
 suppliers and subcontractors and many others were found to be the least causes of closeout
 problems with a 14%.From the study, controlling mechanisms for closeout problems were
 identified and making closeout a priority 22%, accurate punch list coordination and execution
 19%, good workmanship, good quality material, & quality work 17% and good resource
 management 14% were identified as the most effective mechanisms to minimize closeout
 problems. Therefore it is recommended that building closeout stage should not be neglected
 and get a proper management in order to complete the project within the contract time, planned
 cost and within the intended quality.

Reversibility of the non-backtracking random walk

description: Let $G$ be a connected graph of uniformly bounded degree. A $k$ non-backtracking random walk ($k$-NBRW) $(X_n)_{n =0}^{\infty}$ on $G$ evolves according to the following rule: Given $ (X_n)_{n =0}^{s}$, at time $s+1$ the walk picks at random some edge which is incident to $X_s$ that was not crossed in the last $k$ steps and moves to its other end-point. If no such edge exists then it makes a simple random walk step. Assume that for some $R>0$ every ball of radius $R$ in $G$ contains a simple cycle of length at least $k$. We show that under some "nice" random time change the $k$-NBRW becomes reversible. This is used to prove that it is recurrent iff the simple random walk is.

description: Abstract Background Vaccine hesitancy forms a critical barrier to the uptake of COVID-19 vaccine especially in resource-rich countries, which has negative implications on public health. Objective This review aims to summarize levels of COVID-19 hesitancy and its associated factors in high-income countries. Methods A scoping review will be conducted in Medline ®, Embase ®, CINAHL ® and Scopus ® and be reported in accordance to the PRISMA-SCr checklist. The search is current as of March 2021. Studies which evaluated COVID-19 related vaccine hesitancy and its associated factors in high-income countries (> USD$12,535 per capita) will be included. Studies conducted in low and middle-income countries will be excluded. Factors associated with vaccine hesitancy will be grouped into 3 themes (vaccine specific, individual/group or contextual related influences). Significance of study Findings from this scoping review will allow healthcare administrators and policymakers to better understand the determinants of vaccine related hesitancy in high-income countries and allow the design of targeted interventions to improve vaccine uptake within their populations.

description: We study the process of absorption or emission of a bosonic collective excitation by a fermionic quasiparticle in a superfluid of paired fermions. From the RPA equation of motion of the bosonic excitation annihilation operator, we obtain an expression of the coupling amplitude of this process which is limited neither to resonant processes nor to the long wavelength limit. We confirm our result by independently deriving it in the functional integral approach using the gaussian fluctuation approximation, and by comparing it in the long wavelength limit to the quantum hydrodynamic result. Last, we give a straightforward application of the coupling amplitude we obtain by calculating the lifetime of the bosonic excitations of arbitrary wave number. We find a mode quality factor that decreases from its maximum at low wave numbers and vanishes when the bosonic branch hits the pair-breaking continuum.

Physiological Gaussian Process Priors for the Hemodynamics in fMRI Analysis

description: Background: Inference from fMRI data faces the challenge that the hemodynamic system that relates neural activity to the observed BOLD fMRI signal is unknown. New Method: We propose a new Bayesian model for task fMRI data with the following features: (i) joint estimation of brain activity and the underlying hemodynamics, (ii) the hemodynamics is modeled nonparametrically with a Gaussian process (GP) prior guided by physiological information and (iii) the predicted BOLD is not necessarily generated by a linear time-invariant (LTI) system. We place a GP prior directly on the predicted BOLD response, rather than on the hemodynamic response function as in previous literature. This allows us to incorporate physiological information via the GP prior mean in a flexible way, and simultaneously gives us the nonparametric flexibility of the GP. Results: Results on simulated data show that the proposed model is able to discriminate between active and non-active voxels also when the GP prior deviates from the true hemodynamics. Our model finds time varying dynamics when applied to real fMRI data. Comparison with Existing Method(s): The proposed model is better at detecting activity in simulated data than standard models, without inflating the false positive rate. When applied to real fMRI data, our GP model in several cases finds brain activity where previously proposed LTI models does not. Conclusions: We have proposed a new non-linear model for the hemodynamics in task fMRI, that is able to detect active voxels, and gives the opportunity to ask new kinds of questions related to hemodynamics.

Bridge foundation failure & Modification strategies : A Case study of Alemgena District
Creators: name: Fantahun  Aweke
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020
Subjects: Bridge foundation, modification strategy, failure probability and optimization.

description: Bridge foundation failure due to land sliding, scouring, liquefaction, and erosion
 initiate cracking, peel-off, displacement and other visible failure on structural parts of
 the bridge. In Ethiopia significant number of highway bridges foundation are failed by
 flood initiated ground failure. To improve this situation the application optimal
 modification strategies is required to do for the identified bridges at risk. Hence in this
 study it is aimed to formulate optimal model of modification strategies based on
 failure probability, maintenance cost and peak traffic capacity. Maximum Concurrent
 Flow Problem (MCFP), Markov optimal design equation and AMPL optimization
 software were used to develop the model. A simplified four bridge network is used to
 validate the developed model, and then a modified version of the validated model is
 applied to 46 selected bridges from Alemgena district to illustrate the applicability of
 the model under three peak traffic capacity levels of 2800, 3000 and 6000 vehicle per
 day. In all peak traffic capacity level the output analyzed by the model decides 7
 bridges to be replaced with new. For the current peak traffic that is 3000 vehicle per
 day and for the higher future peak capacity of 6000 vehicle per day the model output
 decide similar modification strategies, that indicate the modification strategies applied
 for current peak traffic capacity can manage the traffic peak capacity greater than
 current. For traffic peak capacity lower than current peak traffic capacity that is 2800
 vehicle per day, the model output decides for 22 bridges to do-nothing strategies,
 which is greater in number when compared to 17 bridges that decided for 3000 and
 6000 vehicle per day. Thus the results of the case study justify the importance of
 optimization in modification strategies for bridge foundation failure to cope up with
 the future unexpected peak traffic capacity increase due to geo-hydraulic hazard in the
 highway network

description: We study operator insertions into 1/2 BPS Wilson loops in N = 6 ABJM theory and investigate their two-point correlators. In this framework, the energy emitted by a heavy moving probe can be exactly obtained from some two-point coefficients of bosonic and fermionic insertions. This allows us to confirm an early proposal for computing the Bremsstrahlung function in terms of certain supersymmetric circular Wilson loops, whose value might be accessible to localization techniques. In the derivation of this result we also elucidate the structure of protected multiplets in the relevant superconformal defect theory and perform an explicit two-loop calculation.

description: We use Stein's method to obtain a bound on the distance between scaled $p$-dimensional random walks and a $p$-dimensional (correlated) Brownian Motion. We consider dependence schemes including those in which the summands in scaled sums are weakly dependent and their $p$ components are strongly correlated. As an example application, we prove a functional limit theorem for exceedances in an $m$-scans process, together with a bound on the rate of convergence. We also find a bound on the rate of convergence of scaled U-statistics to Brownian Motion, representing an example of a sum of strongly dependent terms.

description: The present study aimed to determine linear alkylbenzenes (LABs) concentrations as organic molecular marker for sewage pollution in the sediment samples collected from Coast of Port Dickson and Kim Kim River, Peninsular Malaysia. The adverse effects of anthropogenic inputs into the rivers and coastal environment could be detected by molecular organic markers such as LABs. The sediments were processed; their sources were identified and tested by gas chromatography-mass spectrometry (GC-MS). The significance of the differences among sampling stations for LAB concentrations and distribution at p < 0.05 was performed by analysis of variance and Post Hoc Tests, LSD procedures (ANOVA) and Pearson correlation coefficient. LABs indices which include internal to external (I/E) congeners, long to short chains L/S and homologs C13/C12 were used to identify the sewage treatment and degradation levels. Results of this study are statistically uncovered that the range of ΣLABs concentration in the investigated locations was between 112.0; 88.3 and 256.0; 119.0 ng·g−1 dw, respectively. There was significant difference (p < 0.05) of LAB homologs with high percentage of C13-LAB homologs along sampling locations. The calculated LAB ratios (I/E) were within the range between 2.0; 1.7 and 4.1, 2.0, demonstrated that, the treated effluents from primary and secondary sources were discharged to the study areas. The degradation of LABs was 40–64% and 34–38% in the studied locations. The findings of this study suggested the powerfully indicators of LABs in tracing anthropogenic sewage contamination and the necessity of continuing wastewater treatment system improvement.

description: Cancer is one of the most dangerous diseases in the world. The brain tumor is one type of
 cancer that rapidly and uncontrollable growth of abnormal tissues that damages the nearby
 healthy tissues of the brain. The classification and segmentation of brain tumors from MRI
 being performed manually by medical experts. A large quantity of time was spent by
 radiologists and doctors for the identification of tumors and segmenting it from different brain
 tissues. However, actual labeling brain tumors could be a long task, and segmentation of
 tumors is a tedious task for doctors. The brain MRI dataset is collected from a pioneer
 diagnosis center located at Addis Ababa Ethiopia. Deep convolutional layers become a
 popular algorithm to overcome the problems traditional machine learning algorithms by
 automatically feature extraction from the input spaces and accurately detect the brain tumors.
 Transfer learning is explored by freezing layers and fine-tuning pre-trained model of
 convolutional neural network architectures using MRI slices of brain tumor datasets.
 Therefore, accurately predict the brain tumor is significant to give pre-treatment of the patient
 and to improve the existence of patients with tumors. So, the convolutional neural network
 model is proposed by modifying the VGG16 pre-trained model using a deep learning approach
 to classify normal and abnormal brain tumors. The proposed convolutional neural network
 model is trained using 3000 MRI, and data augmentation techniques applied to generate more
 MRI slices to improve the performance of algorithms and reduce overfitting problems. The
 performance of the proposed convolutional neural network model is tested using 800 MRI
 datasets. To segment the abnormal region of tumors and the area of the tumor using optimized
 Fuzzy C Means algorithms. The mean accuracy of the proposed convolutional neural network
 model is found to be 98% for brain tumor classifications with mini-batch size 32 and learning
 rate 0.001. The final performance metrics for brain tumor segmentation used the Jaccard
 similarity index is 90.81 %, the Dice similarity score is 95.16 %, the sensitivity is 96.54 %, and
 the specificity is 94.75% accuracy results using the proposed algorithms. To identify brain
 tumor stages and annotate the abnormal brain tumors by using domain experts is
 recommended as future work

description: As pyrazoles are familiar for showing various biological properties, a series of novel isocoumarin tethered carbothioamide linked pyrazole derivatives were prepared successfully in the presence of environmental favor conditions and evaluated for their pathogenic resistance against four bacteria and two fungi, showing significant activity against different microbial except compound 5d. Among the active compounds, 5f displayed highest antimicrobial property. In fact, 5b and 5l motifs showing good inhibitory activity. Further, a detailed structure activity relationship also discussed, which revealed that the presence of electron withdrawing -NO2 group in 5f compound may delivered highest biological property, while the amino group attached in compound 5d delivered inactive antibacterial property. Moreover, computer aided studies of biologically effective compounds to determine the interactions and docking score with the crystal structure of Escherichia coli 24 kDa DNA gyrase subunit B in complex with clorobiocin. It was observed that the amino acid residues present in the active binding site of the protein1KZN can frequently interact with targets.

description: We study the emergence of two-dimensional conformal symmetry in critical quantum spin chains on the finite circle. Our goal is to characterize the conformal field theory (CFT) describing the universality class of the corresponding quantum phase transition. As a means to this end, we propose and demonstrate automated procedures which, using only the lattice Hamiltonian $H = \sum_j h_j$ as an input, systematically identify the low-energy eigenstates corresponding to Virasoro primary and quasiprimary operators, and assign the remaining low-energy eigenstates to conformal towers. The energies and momenta of the primary operator states are needed to determine the primary operator scaling dimensions and conformal spins -- an essential part of the conformal data that specifies the CFT. Our techniques use the action, on the low-energy eigenstates of $H$, of the Fourier modes $H_n$ of the Hamiltonian density $h_j$. The $H_n$ were introduced as lattice representations of the Virasoro generators by Koo and Saleur [Nucl. Phys. B 426, 459 (1994)]. In this paper we demonstrate that these operators can be used to extract conformal data in a nonintegrable quantum spin chain.
