Authors: Żur Agnieszka
Published: February 2021

Rozwój praktyk podwykonawstwa uznany jest w literaturze tematu za metodę stymulowania rozwoju małych i średnich przedsiębiorstw oraz jako sposób kreowania okazji rynkowych. Podwykonawstwo tradycyjnie kojarzone jest z relacją dużych i rozwiniętych przedsiębiorstw, często międzynarodowych, z mniejszymi i słabszymi graczami rynkowymi, którzy świadczą usługi podwykonawstwa większym partnerom. Niniejszy artykuł skupia się na podwykonawstwie opartym na obustronnie korzystnej relacji mniejszych podmiotów i prezentuje sytuacje, w których partnerska relacja podwykonawstwa jest okazją przedsiębiorczą. Artykuł przedstawia poszczególne kategorie powodów, dla których małe i średnie przedsiębiorstwa mogą angażować się w partnerskie podwykonawstwo. Opracowanie poddaje analizie podwykonawstwo, odwołując się do teorii przedsiębiorczości okazji jako podstawowej jednostki badawczej tej teorii. Praca omawia determinanty identyfikacji i eksploatacji okazji przedsiębiorczych w kontekście podwykonawstwa oraz przedstawia przedsiębiorczą orientację w podwykonawstwie na przykładzie podwykonawców przetwórstwa rybnego w północno-zachodniej Polsce. Podsumowaniem rozważań jest propozycja modelu badawczego podwykonawstwa przemysłowego oraz egzemplifikacja przedstawionych związków na przykładzie lokalnego przemysłu przetwórstwa rybnego w północno-zachodniej Polsce.

A Composition and Abundance of Alien Fish Species in Inland Waters, Southern Iraq
Authors: Abdullah Abdul Hussein J. , Abdullah Sajad A. , Yaseen Ali T.
Published: February 2021

Alien fish species have negative effects on the abundance, diversity and richness of native fish species in southern Iraq. The numbers of alien fish species are constantly increasing due to the entry of invasive species. This has resulted in shifts in the historical composition of fish community structure and scarcity of some native species which represent the keystone in the building of fish populations.

    Fish samples were monthly collected from three sites in southern Iraq (Al-Chibyaish marsh, the lower parts of Euphrates River, and the northern part of Shatt Al-Arab River) from April 2017 to June 2018. A total of 14,853 individuals of fish were sampled, which represented 26 species, 24 genera and 13 families of bony fishes. Ten alien fish species were recorded, affiliated to nine genera and five families, namely Cichlidae, Cyprinidae, Heteropneustidae, Poeciliidae and Xenocyprididae. Three alien fish species dominated the abundance in the three sites; the Prussian carp Carassuis gibelio comprised 12.58%, 26.19%, and 13.84%, the Blue tilapia Oreochromis aureus formed 16.78%, 13.66%, and 18.79%, , and the Redbelly tilapia Coptodon zillii comprised 7.37%, 7.71%, and 14.66% of the total number of species in three study sites respectively. (  â€¦. )

     These alien fish species created serious shifting in fish composition, diversity, richness, and abundance of native fish populations in comparison to the results of the historical survey in southern Iraq.
The religious genres of collective memory – an attempt at typology
Authors: Wójcicka Marta
Published: February 2021

The memory genre as a model of text serves to memorize (shape) and remember (pass on) images of the past, which reproduces the picture of the past. The article is an attempt at providing typology of religious memory genres. In the first part of the article, the concept of the memory genre is presented and an attempt is made at typology of religious memory genres, making use of the conceptions of Jan Assmann who distinguished communicative and cultural kinds within collective memory. According to the author, the religious genres of cultural memory include the liturgical prayer and the fixed prayer. On the other hand, instances of the religious genres of communicative memory are the universal prayer and parish announcements. Beside these two types, the author indicates also religious genres of inter-cultural memory, which constitute a connection of different types of memory: communicative and cultural or cultural and individual. Examples of this genre are the examination of conscience and a pastoral letter. Certain genres (e.g. the liturgical prayer) are stored in collective memory in full and should be tied to, primarily, remembering – one of the four phases of memory. Then they make genres of cultural memory. Others are connected with recalling (examination of conscience, a pastoral letter, parish announcement) and are genres of communicative or inter-cultural memory.

Published: February 2021

Writing is considered as a hard language skill for students. English teachers have been trying to find the effective way to enhance their students’ writing skill. One of them is providing feedback in students’ written work, also known as written Feedback. This article retrieved from the research on the effect of online written feedback through social media on students’ writing in SMAN 4 Tanjungpinang. This research aims to find out the effect of Online Written Feedback on students’ writing skill through social media Facebook at SMAN 4 Tanjungpinang. A pre-experimental design with one group pre-test-post-test was used in this research. There were 30 eleventh grade students of SMAN 4 Tanjungpinang as the sample of the research. This research used written assignment as its instrument. A pre-test is administered at the beginning of the research and followed by providing online written feedback on students’ writing personal letter as the treatment. A post-test was also conducted after the treatment. The pre-test and post test scores were analysed by using a paired sample t-test to answer the research hypothesis. This research showed that online written feedback did not significantly affect the students’ writing skill in SMAN 4 Tanjungpinang. There was a difference between the mean score of pre and post-test, from 83.07 to 85.70, but it was not significantly.
Repeat-Until-Success: Non-deterministic decomposition of single-qubit unitaries
Authors: Paetznick Adam , Svore Krysta M.
Published: February 2021

We present a decomposition technique that uses non-deterministic circuits to approximate an arbitrary single-qubit unitary to within distance $\epsilon$ and requires significantly fewer non-Clifford gates than existing techniques. We develop ``Repeat-Until-Success" (RUS) circuits and characterize unitaries that can be exactly represented as an RUS circuit. Our RUS circuits operate by conditioning on a given measurement outcome and using only a small number of non-Clifford gates and ancilla qubits. We construct an algorithm based on RUS circuits that approximates an arbitrary single-qubit $Z$-axis rotation to within distance $\epsilon$, where the number of $T$ gates scales as $1.26\log_2(1/\epsilon) - 3.53$, an improvement of roughly three-fold over state-of-the-art techniques. We then extend our algorithm and show that a scaling of $2.4\log_2(1/\epsilon) - 3.28$ can be achieved for arbitrary unitaries and a small range of $\epsilon$, which is roughly twice as good as optimal deterministic decomposition methods.
Geometric phase carried by the observables and its application to quantum computation
Authors: Wang Zisheng , Pan Hui
Published: February 2021

We investigate geometric phases in terms of Heisenberg equation. We find that, equivalently to Schr\"odinger picture with a memory of its motion in terms of the geometric phase factor contained in the wave function, the observales carry with the geometric message under their evolutions in the Heisenberg picture. Such an intrinsic geometric feature may be particularly useful to implement the multi-time correlation geometric quantum gate in terms of the observables, which leads to a possible reduction in experimental errors as well as gate timing. An application is discussed for nuclear-magnetic-resonance system, where the geometric quantum gate is proposed.
Leakage suppression in the toric code
Authors: Suchara Martin , Cross Andrew W. , Gambetta Jay M.
Published: February 2021

Quantum codes excel at correcting local noise but fail to correct leakage faults that excite qubits to states outside the computational space. Aliferis and Terhal \cite{aliferis07} have shown that an accuracy threshold exists for leakage faults using gadgets called leakage reduction units (LRUs). However, these gadgets reduce the accuracy threshold and increase overhead and experimental complexity, and these costs have not been thoroughly understood. We explore a variety of techniques for leakage-resilient, fault-tolerant error correction in topological codes. Our contributions are threefold. First, we develop a leakage model that is physically motivated and efficient to simulate. Second, we use Monte-Carlo simulations to survey several syndrome extraction circuits. Third, given the capability to perform 3-outcome measurements, we present a dramatically improved syndrome processing algorithm. Our simulations show that simple circuits with one extra CNOT per check operator and no additional ancillas reduce the accuracy threshold by less than a factor of $4$ when leakage and depolarizing noise rates are comparable. This becomes a factor of $2$ when the decoder uses 3-outcome measurements. Finally, when the physical error rate is less than $2\times 10^{-4}$, placing LRUs after every gate may achieve the lowest logical error rates of all of the circuits we considered. We anticipate that the closely related planar codes might exhibit the same accuracy thresholds and that the ideas may generalize naturally to other topological codes.
Monte Carlo simulation of stoquastic Hamiltonians
Authors: Bravyi Sergey
Published: February 2021

Stoquastic Hamiltonians are characterized by the property that their off-diagonal matrix elements in the standard product basis are real and non-positive. Many interesting quantum models fall into this class including the Transverse field Ising Model (TIM), the Heisenberg model on bipartite graphs, and the bosonic Hubbard model. Here we consider the problem of estimating the ground state energy of a local stoquastic Hamiltonian $H$ with a promise that the ground state of $H$ has a non-negligible correlation with some `guiding' state that admits a concise classical description. A formalized version of this problem called Guided Stoquastic Hamiltonian is shown to be complete for the complexity class $\MA$ (a probabilistic analogue of $\NP$). To prove this result we employ the Projection Monte Carlo algorithm with a variable number of walkers. Secondly, we show that the ground state and thermal equilibrium properties of the ferromagnetic TIM can be simulated in polynomial time on a classical probabilistic computer. This result is based on the approximation algorithm for the classical ferromagnetic Ising model due to Jerrum and Sinclair (1993).
Quantum circuits and Spin(3n) groups
Authors: Vlasov Alexander Yu.
Published: February 2021

All quantum gates with one and two qubits may be described by elements of Spin groups due to isomorphisms Spin(3)\isomSU(2) and Spin(6)\isomSU(4). However, the group of n-qubit gates SU(2^n) for n>2 has bigger dimension than Spin(3n). A quantum circuit with one- and two-qubit gates may be used for construction of arbitrary unitary transformation SU(2^n). Analogously, the `$Spin(3n)$ circuits' are introduced in this work as products of elements associated with one- and two-qubit gates with respect to the above-mentioned isomorphisms. The matrix tensor product implementation of the Spin(3n) group together with relevant models by usual quantum circuits with 2n qubits are investigated in such a framework. A certain resemblance with well-known sets of non-universal quantum gates (e.g., matchgates, noninteracting-fermion quantum circuits) related with Spin(2n) may be found in presented approach. Finally, a possibility of the classical simulation of such circuits in polynomial time is discussed.
Complementarity between signaling and local indeterminacy
Authors: Aravinda S. , Srikanth R.
Published: February 2021

The correlations that violate the CHSH inequality are known to have complementary contributions from signaling and local indeterminacy. This complementarity is shown to represent a strengthening of Bell's theorem, and can be used to certify randomness in a device-independent way, assuming neither the validity of quantum mechanics nor even no-signaling. We obtain general nonlocal resources that can simulate the statistics of the singlet state, encompassing existing results. We prove a conjecture due to Hall (2010) and Kar et al. (2011) on the complementarity for such resources.
The Trotter step size required for accurate quantum simulation of quantum chemistry
Authors: Poulin David , Hastings M. B. , Wecker D. , Wiebe N. , Doberty Andrew C. , Troyer M.
Published: February 2021

The simulation of molecules is a widely anticipated application of quantum computers. However, recent studies [1, 2] have cast a shadow on this hope by revealing that the complexity in gate count of such simulations increases with the number of spin orbitals N as N8 , which becomes prohibitive even for molecules of modest size N ∼ 100. This study was partly based on a scaling analysis of the Trotter step required for an ensemble of random artificial molecules. Here, we revisit this analysis and find instead that the scaling is closer to N6 in worst case for real model molecules we have studied, indicating that the random ensemble fails to accurately capture the statistical properties of real world molecules. Actual scaling may be significantly better than this due to averaging effects. We then present an alternative simulation scheme and show that it can sometimes outperform existing schemes, but that this possibility depends crucially on the details of the simulated molecule. We obtain further improvements using a version of the coalescing scheme of [1]; this scheme is based on using different Trotter steps for different terms. The method we use to bound the complexity of simulating a given molecule is efficient, in contrast to the approach of [1, 2] which relied on exponentially costly classical exact simulation.
Some classes of concatenated quantum codes: constructions and lower bounds
Authors: Fujita Hachiro
Published: February 2021

In classical coding theory code concatenation is successfully used to construct good errorcorrecting codes and most of the asymptotically good codes known so far are based on concatenation. In this paper we present some classes of asymptotically good concatenated quantum codes, which are a quantum analogue of classical concatenated codes, and derive lower bounds on the minimum distance and the rate of the codes. Our bounds improve on the best lower bound of Ashikhmin–Litsyn–Tsfasman and Matsumoto for rates smaller than about one half. We also give a polynomial-time decoding algorithm for the codes that can decode up to one fourth of the lower bound on the minimum distance of the codes.
High performance information reconciliation for QKD with CASCADE
Authors: Pedersen Thomas Brochmann , Toyran Mustafa
Published: February 2021

It is widely accepted in the quantum cryptography community that interactive information reconciliation protocols, such as cascade, are inefficient due to the communication overhead. Instead, non-interactive information reconciliation protocols based on i.e. LDPC codes or, more recently, polar codes have been proposed. In this work, we argue that interactive protocols should be taken into consideration in modern quantum key distribution systems. In particular, we demonstrate how to improve the performance of cascade by proper implementation and use. Our implementation of cascade reaches a throughput above 80 Mbps under realistic conditions. This is more than twice the throughput previously demonstrated in any information reconciliation protocol.

Published: February 2021

In present paper we show results of ball-on-disk wear experiment of MoS2 film deposited on Ti6Al4V substrate. The ball materials is aluminum oxide. The tests are performed for different surrounding temperature conditions: 20 oC, 200 oC and 350 oC. It is shown that depth of the wear groove increases with increasing surrounding temperature. A finite element modeling approach is next developed to mimic the experimental observations of ball-on-disk wear process. It is based on the assumption of steady state condition developed during short time scale at contact region. The steady state results can next be applied to long time scale in which wear process is numerically simulated. Model results are compared with experimentally obtained wear groove and show satisfactory agreement.

This study revealed the strengths, weaknesses, and effectiveness of the flipped classroom with CALL in EFL writing class. A mixed-method approach was used to achieve the goals of the study. An embedded quasi-experimental methodology design was used to achieve the aims of this study (i.e., quantitative and qualitative data analysis). There were a hundred and fifty Indonesian EFL university learners who participated in this study. This study also involved 14 EFL writing teachers who experienced implementing the flipped classroom with CALL from five universities. The results of this study revealed that a flipped classroom with CALL in EFL writing class has many advantages, such as stimulating learner autonomy, improving teaching and learning processes, providing more time for EFL writing and input during face-to-face meetings, promoting active learning, student learning responsibility, and peer collaboration. Besides, some drawbacks were also found from its implementation. However, implementing the flipped classroom in the current study positively affects the EFL writing course. This study implies that teachers can include online resources such as videos from reputable sources or make their videos as learning materials if possible.

Authors: Pramoedyo Henny , Riza Sativandi , Oktaviarina Afiati , Ardianti Deby
Published: February 2021

Land resource management requires extensive land mapping. Conventional soil mapping takes a long time and is expensive; therefore, geographic information system data as a predictor in soil texture modeling can be used as an alternative solution to shorten time and reduce costs. Through digital elevation model data, topographic variability can be obtained as an independent variable in predicting soil texture. Geographically weighted regression is used to observe the effects of spatial heterogeneity. This study uses a data set of 50 observation points, each of which had soil particle-size fraction attributes and eight local morphological variables. The covariates used in this study are eastness aspects, northness aspects, slope, unsphericity curvature, vertical curvature, horizontal curvature, accumulation curvature, and elevation. Prediction using geographically weighted regression shows more results compared to multiple linear regression models. The spatial location can affect product Y, with the R2 value of 0.81 in the sand fraction, 0.57 in the silt fraction, and 0.33 in the clay fraction.

Perkembangan bangunan infrastruktur di Indonesia sangat signifikan, mulai dari perkembangan jalan bebas hambatan (jalan tol), gedung – gedung bertingkat, jembatan, bendungan, drainase dan infrastruktur yang lain. Strong Column  Weak Beam merupakan analisa perencanaan yang dipakai di Indonesia karena ketika struktur mengalami keruntuhan maka balok akan runtuh terlebih dahulu dibanding dengan kolom. Sehingga akan lebih aman dibanding dengan analisa yang lain. Struktur kolom memiliki peranan yang mendasar saat perencanaan sebuah gedung. Dimensi (ukuran), material penyusunnya dan pembebanan merupakan kunci dari perencanaan. Sehingga diperlukan penelitian mengenai pengaruh dimensi kolom pada struktur strong column  weak beam gedung lantai 3 – lantai 7 akibat gaya gempa. Dari hasil analisis menggunakan software SAP2000 lantai 7 mengalami keruntuhan pada kolom berdimensi 40x40, karena lantai 7 memiliki ketinggian yang relative tinggi. Pembebanan gempa statis pada analisis berpengaruh besar dengan gaya axial sebesar 228,446 ton/m. Dimensi kolom yang paling efektif menerima beban gempa di daerah zona 4 adalah 60x60.

THE EFFECT OF ADDITION OF GREEN GLASS POWDER ON THE STRENGTH OF CONE BLOCK PRESSING
Authors: Mudiyono Rachmat
Published: February 2021

At this time the manufacture of products using waste has been developed. One of them is a cone block. In this study, the addition of green glass powder material will be carried out in order to determine the effect on the quality of the cone block. The addition of green glass powder aims to determine the difference in compressive strength against the conventional model cone block. The silica content contained in green glass powder is in the form of pozzolanic substances, a substance in the form of a cement-like content and can replace cement. This study modified the cone block with a mixture of green glass powder from a percentage of 8%, 10% and 15%.
Penbased on previous research which states that the addition of more than 10% silica will affect the cone block structure. Tests carried out on cone blocks, namely the compressive strength test. The results of the cone block research on the compressive strength test, in general, the mixed cone block of 8%, 10% and 15% compressive strength decreased due to the slowing of the binding process due to the reduction of the cement element except for the cone block aged 14 days with a mixture percentage of 8% which had an increase.

The authors analyze the response of the Russian government to the shrinking of household incomes during the 2020 economic crisis — the social support measures that were put in place to check the increase in poverty, and the social groups that were targeted by direct federal cash benefits. The anticrisis social support measures in Russia were, on the whole, comparable in composition and scope to what the governments in other countries were doing. A special feature of the Russian approach was that the new social benefits and the increased amounts of already existing benefits were addressed exclusively to families with children and were granted irrespective of household income levels. The authors estimate that the additional social support benefits, had they been implemented before the crisis, would have reduced the pre-crisis level of poverty by almost one third, although seven out of ten Russian households were left out of this additional support because they had no underage children. This leads to the conclusion that, in the future, social support policies must change to meet new challenges not only quickly, as they did during the last year’s crisis, but also in a more targeted manner.
