Background information: Kytococcus sedentarius is an opportunistic pathogen that can survive on and inside humans. Understanding the genetics of this organism and its biologic pathways can lead to better treatments in addition to possible uses of the gene protein products it produces.
Purpose: The purpose of this study was to use in silico gene annotation to characterize five genes in the DNA mismatch repair pathway of K. sedentarius.
Methods: This study used the IMG-ACT website to record data in a digital notebook. The gene details page was accessed for basic information on each gene. Databases such as BLAST, CDD, TIGRFAM, PDB, PSORT-B, MetaCyc, and Prosite were used to collect qualitative and quantitative data for the five genes, including similar genes in other organisms, functional families, crystal structures, localization, and the presence of necessary functional residues. Websites like Phylogeny.fr, Pfam, KEGG, TMHMM, SignalP, Web Logo, and Phobius were used to generate diagrams that used in the analysis.
Conclusions: The proposed annotations for all five genes were confirmed. The genes were found to be phylogenetically conserved between K. sedentarius and multiple orthologs.

Noisy quantum Monty Hall game
The influence of spontaneous emission channel and generalized Pauli channel
on quantum Monty Hall Game is analysed. The scheme of Flittney and Abbott is
reformulated using the formalism of density matrices. Optimal classical
strategies for given quantum strategies are found. The whole presented scheme
illustrates how quantum noise may change the odds of a zero-sum game.Comment: 10 pages, 3 figure
Noise Effects in Quantum Magic Squares Game
In the article we analyse how noisiness of quantum channels can influence the
magic squares quantum pseudo-telepathy game. We show that the probability of
success can be used to determine characteristics of quantum channels. Therefore
the game deserves more careful study aiming at its implementation.Comment: 5 figure
Unintegrated gluon distributions and Higgs boson production in proton-proton collisions
Inclusive cross sections for Higgs boson production in proton-proton
collisions are calculated in the formalism of unintegrated gluon distributions
(UGDF). Different UGDF from the literature are used. Although they were
constructed in order to describe the HERA deep-inelastic scattering data,
they lead to surprisingly different results for Higgs production. We present
both two-dimensional invariant cross section as a function of Higgs rapidity
and transverse momentum, as well as corresponding projections on rapidity or
transverse momentum. We quantify the differences between different UGD's by
applying different cuts on interrelations between transverse momentum of Higgs
and transverse momenta of both fusing gluons. We focus on large rapidity
region. The interplay of the gluon-gluon fusion and weak-boson fusion in
rapidity and transverse momentum is discussed. We find that above
50-100 GeV the weak-gauge-boson fusion dominates over gluon-gluon fusion.Comment: 32 pages, 18 figures, corrected version, restructured, misprints

Extending scientific computing system with structural quantum programming capabilities
We present a basic high-level structures used for developing quantum
programming languages. The presented structures are commonly used in many
existing quantum programming languages and we use quantum pseudo-code based on
QCL quantum programming language to describe them. We also present the
implementation of introduced structures in GNU Octave language for scientific
computing. Procedures used in the implementation are available as a package
quantum-octave, providing a library of functions, which facilitates the
simulation of quantum computing. This package allows also to incorporate
high-level programming concepts into the simulation in GNU Octave and Matlab.
As such it connects features unique for high-level quantum programming
languages, with the full palette of efficient computational routines commonly
available in modern scientific computing systems. To present the major features
of the described package we provide the implementation of selected quantum
algorithms. We also show how quantum errors can be taken into account during
the simulation of quantum algorithms using quantum-octave package. This is
possible thanks to the ability to operate on density matrices
Numerical simulations of mixed states quantum computation
We describe quantum-octave package of functions useful for simulations of
quantum algorithms and protocols. Presented package allows to perform
simulations with mixed states. We present numerical implementation of important
quantum mechanical operations - partial trace and partial transpose. Those
operations are used as building blocks of algorithms for analysis of
entanglement and quantum error correction codes. Simulation of Shor's algorithm
is presented as an example of package capabilities.Comment: 6 pages, 4 figures, presented at Foundations of Quantum Information,

Nonphotonic electrons at RHIC within -factorization approach and with experimental semileptonic decay functions
We discuss production of nonphotonic electrons in proton-proton scattering at
RHIC. The distributions in rapidity and transverse momentum of charm and bottom
quarks/antiquarks are calculated in the -factorization approach. We use
different unintegrated gluon distributions from the literature. The
hadronization of heavy quarks is done by means of Peterson and Braaten et al.
fragmentation functions. The semileptonic decay functions are found by fitting
recent semileptonic data obtained by the CLEO and BABAR collaborations. We get
good description of the data at large transverse momenta of electrons and find
a missing strength concentrated at small transverse momenta of electrons.
Plausible missing mechanisms are discussed.Comment: 16 pages, 11 figure
Inclusive production of meson in proton-proton collisions at BNL RHIC
Inclusive cross sections for production in proton-proton collisions
were calculated in the -factorization approach for the RHIC energy.
Several mechanisms were considered, including direct color-singlet mechanism,
radiative decays of mesons, decays of , open-charm associated
production of as well as weak decays of B mesons. Different
unintegrated gluon distributions from the literature were used. We find that
radiative decays and direct color-singlet contributions constitute the
dominant mechanism of production. These process cannot be consistently
treated within collinear-factorization approach. The results are compared with
recent RHIC data. The new precise data at small transverse momenta impose
stringent constraints on UGDFs. Some UGDFs are inconsistent with the new data.
The Kwieci\'nski UGDFs give the best description of the data. In order to
verify the mechanism suggested here we propose -- jet correlation
measurement and an independent measurement of meson production in
and/or decay channels. Finally, we address the issue of
\J spin alignment.Comment: 26 pages, 20 figures, the text was slightly modified, the title was

Scaling-up beginning farmers for wholesale production
With nearly 15 million people that live within 250 miles of Kansas City, the demand for local food is increasing. Local beginning farmers in the region want to reach an emerging wholesale market. However, selling directly to consumers demands different skills than the wholesale market requires. There are many educational programs offered in the region that are focused on direct to consumer sales. Unfortunately, there is a gap in educational programs that are offered to support beginning farmers that wish to expand into wholesale markets. In 2018, the Beginning Farmer Wholesale Project was started within the Growing Growers Kansas City program in congruence with the overall mission to improve the skills and livelihoods of the region’s growers. The project offers support and training to beginning farmers as they begin to navigate new market opportunities. It provides on-farm technical assistance, mentorship, opportunities to connect to wholesale buyers, a workshop series, a manual and an extensive foodshed GIS map. The ongoing project has seen several contributions to improving farmer access to wholesale markets. As of 2020, six workshops have been conducted that have covered a variety of farm production and marketing skills. Six farmer mentees have enrolled in the mentor program which enlists nine farmer mentors from across the region. Over twenty farmers have utilized the technical assistance service on their Kansas and Missouri farm operations and the farmer buyer matching program has resulted in thirteen beginning farmers gaining access to new markets. The project highlights the value of collaboration among organizations and the importance of offering multiple farmer services in order to improve wholesale access
