Anthrax poses a pressing issue for veterinary medicine and public health in many countries, including the Russian Federation, which necessitates the improvement and development of new, sensitive and specific diagnostic tools.

The aim of the work was to create an experimental peroxidase conjugate for the detection of specific antibodies to the anthrax pathogen and to optimize the conditions for performing enzyme immunoassay (ELISA).

Materials and methods. The peroxidase conjugate was constructed using horseradish peroxidase and Staphylococcus aureus protein A (Sigma-Aldrich, USA). Bacterial antigens isolated from strains of Bacillus anthracis 55ΔTPA-1Spo, B. anthracis Sterne 34 F2 were used as sensitizing agents. The developed experimental batches of the conjugate were tested in ELISA for the ability to bind antibodies in the blood sera of anthrax patients and vaccinated individuals. The sensitivity, specificity, and accuracy of the method were calculated using the built-in functions of the ROCR software package.

Results and discussion. The peroxidase conjugate to detect specific antibodies to the anthrax pathogen in the study of clinical material has been developed; conditions for the ELISA performance have been optimized. To interpret the results of the study, a threshold value of the positivity coefficient was used, below which the result was considered negative, and at an equal or higher value, positive. The test demonstrated significant differences in the “positivity coefficient” indicator for the “Healthy”/“Sick” and “Healthy”/“Vaccinated” groups, while the differences between the “Sick”/“Vaccinated” groups were statistically insignificant. The maximum accuracy of the method was observed at blood serum dilutions of 1:250 and 1:500. 100 % intra-run, run-to-run and series-to-series reproducibility has been established for all positive samples. The sensitivity and specificity of the experimental peroxidase conjugates were 100 and 95.8 %, respectively, and the accuracy was 97.6 %.
Orthopaedic Society Leadership Diversity and Academic Participation
Authors: Albright Patrick , Banks Evan , Wood Lily , Chambers Caitlin , Van Heest Ann
Published: July 2022

Background:

In the United States, female and minority representation in the field of orthopaedic surgery remains low, and there are few reports regarding orthopaedic society leadership composition, selection criteria, and academic participation. We aimed to determine the demographic composition of national orthopaedic societies and report the academic participation metrics of leadership.

Methods:

This was a mixed-methods study using surveys and publicly available data from national orthopaedic societies for the 2020 to 2021 year. Twenty-four orthopaedic society websites were queried for their transparency in leadership selection and demographic information, including sex, racial, and ethnic composition of overall society and board membership. Data were collected regarding the academic participation of board leadership.

Results:

In total, 19 (79%) of the 24 national orthopaedic societies publish survey data regarding sex and racial demographics. One society elected not to participate, and there was no response from 4 others. Sixteen (89%) of the societies collect sex-related data from their membership, and 19 (100%) report sex-related data for their board members. Five (28%) collect data regarding the race and ethnicity of their general membership, and 10 (53%) report data regarding the race and ethnicity of board members. The average membership was 89% male and 11% female, and the leadership boards were 86% male and 14% female. In the societies that reported on race and ethnicity, on average, 80% of the members were White and 85% of the board members were White. Few societies (13%) publicly list their presidential nominating criteria, and none list their criteria for nonpresidential-line positions. Female sex and ≤10 years in practice were significantly associated with lower Hirsch index (h-index) scores, but these differences dissipated beyond 10 years.

Conclusions:

There is a lack of sex, racial, and ethnic diversity in orthopaedic society leadership. More robust recording of these data by societies can help track improvements in diversity among members and leaders. Academic participation may be one component of leadership selection, but other factors play an important role. Overall transparency of leadership selection criteria could be clarified among orthopaedic societies.
Amyloid Deposition: An Unusual Case of Deep Gluteal Syndrome and Sciatic Nerve Compression
Authors: Parikh Harin B. , Matcuk George R. , Leong Matthew , Vrahas Mark S. , Seruya Mitchel
Published: July 2022

Case:

Soft-tissue amyloidomas are exceedingly rare, with only a few cases reported in the literature. There are no reports of sciatic nerve compression secondary to a soft-tissue amyloidoma. We report a unique case of a 71-year-old man with an incidentally found amyloidoma who was initially believed to have deep gluteal syndrome. He had a favorable outcome after surgical decompression.

Conclusion:

For patients who do not have classic examination and electromyography/nerve conduction findings of piriformis syndrome, providers should explore other etiologies of peripheral nerve compression including soft-tissue amyloidoma.

Influenza B virus (FLUBV) is a major respiratory pathogen of humans. Seasonal influenza vaccines include either one or both FLUBV lineage strains, Victoria, and Yamagata. Vaccine mismatch occurs frequently, particularly in countries where vaccines contain only one of the lineages. We have previously described the safety and efficacy of modified live attenuated FLUBV vaccines based on either virus with rearranged genomes (FluB-RAM and FluB-RANS) or carrying a PB1 segment with a combination of temperature sensitive mutations and a C-terminal HA tag (FluB-att). We compared side by side the immunological responses in female and male DBA/2J mice vaccinated with either one of these vaccines and those with isogenic backbones containing a chimeric HA segment carrying an N-terminal IgA inducing peptide (IGIP). Recombinant viruses with or without the IGIP modification were genetically stable over multiple passages in eggs. In mice, introduction of IGIP improved attenuation of the vaccine candidates, particularly for the FluB-RAM/IGIP compared with the non-IGIP FluB-RAM counterpart. In a prime-boost regimen, mice were completely protected against lethal challenge with a homologous FLUBV strain. Recombinant viruses induced neutralizing antibodies with hemagglutination inhibition titers ≥40. Antibodies against NA and NP were readily detected. Compared to male mice and regardless of the vaccine used, female mice showed a clear trend towards enhanced humoral and cross-reactive IgG and IgA anti-HA responses as well as against NA and NP. The presence of IGIP in the vaccine resulted in an overall trend towards reduced anti-HA responses but enhanced anti-NA and anti-NP responses, particularly of the IgA isotype. Mucosal and serological responses two weeks after challenge showed similar trends with clear differences observed based on sex, vaccine backbone, and whether the vaccine carried the IGIP modification. These findings are significant for the development of universal influenza vaccines.

Peripheral clocks function to regulate each organ and are synchronized though various molecular and behavioral signals. However, signals that entrain the bladder clock remain elusive. Here, we show that glucocorticoids are a key cue for the bladder clock in vitro and in vivo. A pBmal1-dLuc human urothelial cell-line showed significant shifts in gene expression after cortisol treatment. In vivo, rhythmic bladder clock gene expression was unchanged by bilateral adrenalectomy but shifted 4 hours forward by corticosterone administration at the inactive phase. Moreover, the bladder clock shifted 8–12 hours in mice that underwent both bilateral adrenalectomy and corticosterone administration at the inactive phase. These mice saw decreases in the diurnal rhythm of volume voided per micturition, while maintaining diurnal activity rhythms. These results indicate that the diurnal rhythm of glucocorticoid signaling is a zeitgeber that overcomes other bladder clock entrainment factors and coordinates the diurnal rhythm of volume voided per micturition.
WITHDRAWN: Prognostic impact of the expression of NK cell receptor NCR3, CD28 and PD-1 molecular on T cell in peripheral blood of advanced breast cancer patients undergoing paclitaxel chemotherapy
Authors: Yang Ji , Qu Shuxian , Qi Xinhui , Liu Yongming , Qiu Jianing , Yu Ying , Zheng Zhendong , Yu Huiying
Published: July 2022

Background
The main goals of treatment for advanced breast cancer were to prolong survival and improve quality of life. Paclitaxel is a commonly used chemotherapy drug for advanced breast cancer. The occurrence and development of tumors largely depend on the functional state of the immune system. NK cells and T cells are the two main cell subsets who play a key role in tumor immune surveillance and anti-tumor. Their functions mainly depend on the expression of receptors on their surface. This study mainly investigated the correlation between the expression levels of NK cell activating receptors and CD28 and PD-1 molecules on T cells in peripheral blood with prognosis in patients with advanced breast cancer undergoing paclitaxel chemotherapy.
Methods
Peripheral blood was detected by flow cytometry for immunophenotype and PCR technology for detection of NCR transcripts from 53 patients with advanced breast cancer. To compare the differences in immunophenotype and NCR3 transcripts among breast cancer patients with different molecular types. The correlation between immunophenotype and NCR3 splice isomer expression with tumor load, chemotherapy sensitivity to paclitaxel and survival were further analyzed.
Results
The ratio of CD28+/CD28− T cells and NCR3 transcript expression in peripheral blood of triple-negative breast cancer patients was higher than that of patients in other groups. Elevation of NCR3 transcripts mainly inhibits NKp30c. NKp30 on NK cells, NCR3 transcripts, the proportion of CD4+CD28− T cells and PD-1 on T cells were positively correlated with tumor burden in patients. The proportion of CD4+CD28+ T cells was negatively correlated with the tumor burden in patients. After paclitaxel chemotherapy, patients with high expression of CD28 and low expression of PD-1 on T cells before paclitaxel chemotherapy were more sensitive to chemotherapy; patients with low expression level of NKp30 inhibitory splice isomer in NK cells and high ratio of CD28+/PD-1+ T cells before paclitaxel chemotherapy had better PFS.
Conclusion
The expression of NCR3 in NK cells and the expression of CD28 and PD-1 molecules on T cells can be used as potential biomarkers for evaluating tumor progression, chemotherapy effect and prognosis in patients with advanced breast cancer.

In order to solve the problem of insufficient accuracy of consumer recommendation systems, the study proposes to design a new network inference algorithm with bias based on the traditional network inference algorithm. Then the performance of this algorithm is verified by means of comparison experiments with NBI, SNBI and HNBI algorithms. The results show that the new network inference algorithm has an accuracy rate of 24.5%, which is better than the traditional network inference algorithm. In terms of the constituted system performance test, the recommendation hit rate of the novel network inference algorithm increases by 13.97%, which is better than NBI, SNBI, and HNBI. the experimental results indicate that the novel network inference algorithm with bias can improve the performance of the consumer recommendation system, which provides a new idea for the performance improvement of the consumer recommendation system.

This study aimed to establish evidence of the construct validity of the Centre for Epidemiologic Studies Depression Scale Revised – Vietnamese Version (CESDR-V) and a 10-item version of this scale (CESDR-V-10) for use among Vietnamese adolescents. We selected 1084 Grade 10 students in Hanoi using a multiple-stage sampling method. Data supported that the CESDR-V was unidimensional. Cronbach’s alpha coefficient of CESDR-V was 0.92 and CESDR-V-10 was 0.90. All levels of measurement invariance between male and female participants for both CESDR-V and CESD-V-10 were supported well. Both CESDR-V and CESDR-V-10 were positively correlated with Depression Anxiety and Stress Subscales (DASS21)-Depression subscale at stronger levels (convergent pattern) than with DASS21-Anxiety /DASS21-Stress subscales (discriminant pattern). CESDR-V and CESDR-V-10 were negatively correlated with Mental Health Continuum Short Form (a measure of mental well-being) at lower levels than with the DASS21 subscales (discriminant pattern). This study strongly supports the use of the CESDR-V and CESDR-V-10 to screen for depression in Vietnamese adolescents who are attending school.

Ranunculus sect. Auricomus umfasst außer den heimischen Vertretern der R. auricomus-Gruppe und R. pygmaeus eine Reihe weiterer, temperat bis arktisch verbreiteter Arten in Nordamerika und in den Zentralasiatischen Gebirgen. R. sect. Auricomus ist daher nicht mit der/dem vorwiegend apomiktischen R. auricomus-Gruppe / -Komplex (R. auricomus agg.) gleichzusetzen, sondern hat einen größeren taxonomischen Umfang. Die Ranunculus auricomus-Gruppe umfasst im Gebiet der Flora von Zentraleuropa zwei der insgesamt fünf sexuellen Arten des Komplexes sowie eine Reihe von apomiktischen, hybridogenen Taxa. Diese beiden diploiden bis tetraploiden Arten (R. cassubicifolius und R. notabilis) repräsentieren zwei unterschiedliche Morphotypen, die früher als Artengruppen (R. cassubicus L. s.l. und R. auricomus L. s.l.) unterschieden und von manchen Autoren als Subsektionen innerhalb Ranunculus sect. Auricomus klassifiziert oder auch als informelle Artengruppen (Großgruppen, Sammelgruppen, Aggregate, Komplexe) behandelt wurden. Jedoch haben neuere genetische Untersuchungen gezeigt, dass diese morphologisch definierten Gruppen keine Abstammungsgemeinschaften darstellen. Sie werden daher hier nicht aufrechterhalten. Die in manchen Publikationen auch als gleichwertig eingestuften und unterschiedenen Artengruppen des R. fallax und des R. monophyllus werden hier ebenfalls nicht berücksichtigt. Umfassende phylogenomische Untersuchungen zeigen, dass in Europa drei große, unscharf getrennte genetische Cluster vorliegen, die eine West-Ost-Differenzierung zeigen.
Factor Analysis Of Energy Security: Net Import Dependency
Authors: Kolosok Svitlana , Kovalenko Yevhen V.
Published: July 2022

This paper analyzes various aspects of energy dependency and identifies the hidden factors behind national energy security. Based on a review of the scientific literature, the factors that reduce energy security in the consumption of natural gas, oil, and nuclear energy generation were identified. One such factor is import dependency on energy resources. Import dependency on energy is a crucial characteristic of energy security and can exacerbate the effects of external aggression, non-competitive behavior, and pressure. Given the energy crisis of 2022, most countries around the world have revised their energy security policies to reduce import dependency by diversifying supplies and reducing dependence on Russian energy resources. The factor analysis of energy dependency ratios, 1990-2020, was used to study the energy security of the EU27 countries. The factor analysis was performed for annual indices calculated using the Eurostat database of “Simplified energy balances.” The paper hypothesized the existence of latent relationships between energy security variables for the twenty-seven EU countries. The hypothesis was verified using Bartlett’s sphericity test and Kaiser-Meyer-Olkin criterion. The results of hypothesis testing showed its statistical significance (the p-value < 0.05) and the possibility of factor analysis. Correspondence indices also indicated the adequacy of possible prediction of a set of variables. The factor analysis was executed in Python using the FactorAnalyzer module (the release 0.4.0). The principal factor extraction and the varimax rotation model were used to obtain the initial solution, preserving the orthogonality of the loading matrix. The factor structure of the model was confirmed for four factors consisting of the twenty-eight elements. The received four factors model allowed us to describe around 80% of the cumulative variance. It was found that each factor separately explained 46.89%, 15.80%, 10.91%, and 6.39% of the variance, respectively.

Authors: Paul Sanchita , Kalita Abhijit , Kaushik Neha
Published: July 2022

Background: Nodular skin lesions vary significantly in size and colour/pigmentation. Most of these clinically resemble soft tissue lesions. Histopathology plays key role in categorizing the lesions based on which course of treatment is planned. The present study aims to find out incidence and variation of skin nodules and correlate the clinico-pathological details with special reference to ethnic population of Northeast India.

Methods: The study is a retrospective and descriptive study conducted for a period of 2 years at a tertiary care centre. The clinical and demographic details were retrieved and H&E slides are studied for histomorphology.

Result: A total of 50 cases were studied out of which five cases were diagnosed as malignant tumours and 45 cases were diagnosed as benign tumours. Seventeen cases (34%) of tumours with follicular differentiation, eight cases (16%) of melanocytic tumours, nine cases (18%) of vascular and neural tumours, thirteen cases (26%) of tumours with apocrine and eccrine differentiation, two cases (4%) of epidermal tumors and one case (2%) of tumour with sebaceous differentiation were included under the present study. Tumors with follicular differentiation, the most commonly encountered tumor in the present study, were seen in the fourth to sixth decades of life and seen more commonly among women. A total of 18 (36%) cases belonged to ethnic tribal communities of North-east India, out of which seven were tumors of follicular differentiation, five were melanocytic tumours and six were tumors of eccrine differentiation.

Conclusion: H&E-stained sections stand as the most important tool for diagnosing and differentiating skin nodular lesions. A significant percentage (36%) of the lesions in the present study have been seen in the ethnic population of the Northeast region of India.
NUMERICAL INVESTIGATIONS ON THE EFFECTS OF SEABED SHALLOW SOILS ON A TYPICAL DEEPWATER SUBSEA WELLHEAD SYSTEM

Published: July 2022

Deepwater subsea wellheads may be significantly threatened under extreme sea conditions and operations, especially when the seabed is composed of very soft clay properties. A numerical model of a deepwater wellhead system is established using the classic ocean pipe element and nonlinear spring element of ANSYS to examine the behaviors of subsea wellheads in diverse seabed soil. Nonlinear spring elements coded in the APDL language are used to model three types of seabed soils: very soft soil, soft soil, and firm soil. The dynamic and quasi-static behaviors of the wellhead system in the typical coupled and decoupled models of the drilling riser system are particularly investigated in depth. The effects of the nonlinear seabed soil properties on the detailed wellhead are realistically simulated using time domain and extremum analysis. The results show that the softer the seabed soil, the greater the displacement, rotation angle, curvature, and bending moment of deepwater subsea wellheads. When the seabed soil reaches a particular depth, the mechanical characteristics of the wellheads under the three types of seabed soil conditions are almost simultaneously close to zero. Overall, several conclusions reached in this study may provide some useful references for design and stability analysis.
Higher-order corrections to exclusive heavy vector meson production
Authors: Lappi Tuomas , Mäntysaari Heikki , Penttala Jani
Published: July 2022

We present results for higher-order corrections to exclusive
production. This includes the first relativistic correction of order
v^2v2
in quark velocity, and next-to-leading order corrections in
\alpha_sαs
for longitudinally polarized production. The relativistic corrections
are found to be important for a good description of the HERA data,
especially at small values of the photon virtuality. The next-to-leading
order results for longitudinal production are evaluated numerically. We
also demonstrate how the vector meson production provides complementary
information to the structure functions for extracting the initial
condition for the small-xx
evolution of the dipole-proton scattering amplitude.
Phenomenological extraction of a universal TMD fragmentation function from single hadron production in $e^+ e^-$ annihilations

Published: July 2022

Factorizing the cross section for single hadron production in
e^+e^-e+e−
annihilations, differential in z_hzh,
P_TPT
and thrust, is a highly non trivial task. We have devised a
factorization scheme that allows us to recast the
e^+e^- \to hXe+e−→hX
cross section in the convolution of a calculable hard coefficient and a
universal Transverse Momentum Dependent (TMD) Fragmentation Function
(FF). The predictions obtained from our NLO-LL perturbative computation,
together with a simple ansatz to model the non-perturbative part of the
TMD, are applied to the experimental measurements of the BELLE
Collaboration for the phenomenological extraction of this process
independent TMD FF.
Measurements of $W$ and $Z/γ^*$ cross sections and their ratios in $pp$ collisions at STAR
Authors: Nam Jae
Published: July 2022

While the unpolarized parton distribution functions of the valence
quarks (dd

are well determined from DIS experiments, the sea quark counterparts,
\bar{d}d‾
and \bar{u}u‾,
are much less constrained, in particular, near the valence region.
Measurements of W^+/W^-W+/W−
production ratio in pppp
collider experiments, such as the STAR experiment at RHIC, can probe the
\bar{d}/\bar{u}d‾/u‾
ratio at a large Q^2Q2

WW

cross-section measurements using the STAR pppp
collision data at a center-of-mass energy of
\sqrt{s} = 500/510\;\mathrm{GeV}s=500/510GeV
collected in 2011, 2012, 2013 and 2017.
Inclusive and diffractive dijet photoproduction in ultraperipheral heavy ion collisions at the LHC
Authors: Guzey Vadim , Klasen Michael
Published: July 2022

We calculate the cross section of inclusive dijet photoproduction in ultraperipheral collisions (UPCs) of heavy ions at the CERN Large Hadron Collider using next-to-leading order perturbative QCD and demonstrate that it provides a good description of the ATLAS data. We study the role of this data in constraining nuclear parton distribution functions (nPDFs) using the Bayesian reweighting technique and find that it can reduce current uncertainties of nPDFs at small x by a factor of 2. We also make predictions for diffractive dijet photoproduction in UPCs and examine its potential to shed light on the disputed mechanism of QCD factorization breaking in diffraction.
QCD factorization for hadronic quarkonium production at high $p_T$
Authors: Lee Kyle , Qiu Jian-Wei , Sterman George , Watanabe Kazuhiro
Published: July 2022

Heavy quarkonium production at high transverse momentum
(p_TpT)
in hadronic collisions is explored in the QCD factorization approach. We
find that the leading power in the 1/p_T1/pT
expansion is responsible for high p_TpT
regime, while the next-to-leading power contribution is necessary for
the low p_TpT
region. We present the first numerical analysis of the scale evolution
of coupled twist-2 and twist-4 fragmentation functions (FFs) for heavy
quarkonium production and demonstrate that the QCD factorization
approach is capable of describing the p_TpT
spectrum of hadronic J/\psiJ/ψ
production at the LHC.

generalized parton distributions in a very specific way.
Gluon saturation in proton and its contribution to single inclusive soft gluon production in high energy proton-nucleus collisions
Authors: Li Ming
Published: July 2022

The leading order single inclusive soft gluon production in high energy proton-nucleus (pA) collisions has been studied by various approaches for more than two decades. The first correction due to the gluon saturation in proton was analytically attempted recently through a diagrammatic approach in which only partial results were obtained. An important feature of the first saturation correction is that it includes both initial state and final state interactions. In this paper, we present the complete result derived from the Color Glass Condensate framework. Our approach is to analytically solve the classical Yang-Mills equations in the dilute-dense regime and then use the Lehmann-Symanzik-Zimmermann (LSZ) reduction formula to obtain gluon production from classical gluon fields.

Pion GPDs: Constraints, modelling and experimental access
Authors: Morgado Chávez Jose Manuel
Published: July 2022

The study of Generalised Parton Distributions (GPDs) is a hot-topic in hadron physics. Due to its connection with chiral symmetry breaking, assessing those of pions is of great interest. For this reason, we present a novel model-building strategy for pion GPDs capable of fulfilling all of the theoretical constraints required by QCD: support, polynomiality, positivity and soft-pion theorem. The methodology is illustrated with a simple model, and exploited afterwards for the calculation of pions' deeply virtual Compton Scattering (DVCS) Compton Form Factors (CFFs) at NLO. The results show gluon-content to play the dominant role in pions' response to DVCS at EIC kinematics.
Probing gluon density fluctuations at large momentum transfer $|t|$ at HERA
Authors: Kumar Arjun
Published: July 2022

The information on the gluonic structure and its fluctuations is
captured by the differential |t||t|
spectrum in diffractive events. The incoherent cross-section is
sensitive to the fluctuations in the target wavefunction in such events.
We investigate the incoherent epep
cross section in J/\psiJ/ψ
photoproduction using the impact-parameter dependent dipole model. The
spatial gluonic structure is modelled as hotspots of gluon density
having substructure where this substructure is modelled as hotspots
within hotspots. We find that three levels of the substructure provide a
good description of all the data, available up to
|t|=30~|t|=30GeV^22.
We investigate these fluctuations in both the saturated and
non-saturated dipole models and compare our predictions with the HERA
Data.
Production of three isolated photons in the high-energy factorization approach
Authors: Saleev Vladimir
Published: July 2022

We study large-p_TpT
three-photon production at the LHC at the center-of-mass energy
\sqrt{s}=8s=8
TeV. We use the LO approximation of the parton Reggeization approach
consistently merged with the real NLO corrections. For numerical
calculations use the parton-level generator KaTie and modified KMR-type
unintegrated parton distribution functions. We find good agreement
between our predictions and data with the same accuracy as in the NNLO
calculations based on the collinear parton model of QCD. At higher
energies (\sqrt{s}=13s=13
and 27 TeV) parton Reggeization approach predicts larger cross sections,
up to \sim 10∼10
% and \sim 20∼20
%, respectively.
Time reversal-odd effects in QCD and beyond
Authors: Manna Dylan , Signori Andrea , Aidala Christine
Published: July 2022

In this paper we will describe a parallel between phenomenological and symmetry-based descriptions of the process dependence of the time-reversal-odd phenomena in QCD, such as the Sivers effect, with the goal of defining the essential elements that lead to such process dependence in QCD.
This will then serve as a starting point to explore possible generalizations in a different gauge theory.
T-odd quark-gluon-quark correlation function in the light-front quark-diquark model
Authors: Sharma Shubham , Kumar Narinder , Dahiya Harleen
Published: July 2022

We have scrutinized the transverse momentum dependent
quark–gluon–quark correlation function. We have utilized the light-front
quark-diquark model to study the time-reversal-odd interaction-dependent
twist-3 gluon distributions which we have obtained from the
disintegration of the transverse momentum dependent quark–gluon–quark
correlator. Specifically, we have studied the behavior of
\tilde{e}_{L}ẽL
and \tilde{e}_{T}ẽT
while considering our diquark to be an axial-vector.
Top-quark mass determination in the optimised threshold scan
Authors: Nowak Kacper , Zarnecki Aleksander Filip
Published: July 2022

One of the important goals at the future
e^++e^-−
colliders is to measure the top-quark mass and width in a scan of the
pair production threshold. Presented in this work is the most general
approach to the top-quark mass determination from the threshold scan at
CLIC, with all relevant model parameters and selected systematic
uncertainties included in the fit procedure. In the baseline scan
scenario the top-quark mass can be extracted with precision of the order
of 30 to 40,MeV, already for 100 fb^{-1}−1
of data collected at the threshold. We present the optimisation
procedure based on the genetic algorithm with which the statistical
uncertainty of the mass measurement can be reduced by about 20%.

Published: July 2022

We review our transverse momentum dependent factorization and resummation formalism for heavy flavor dijet production at the EIC. In this formalism, we have calculated the heavy flavor mass corrections in the collinear-soft and jet functions, and in the resummed expression for the cross section. By establishing this formalism, we then study the effects of the mass corrections by providing predictions at the EIC for the massive case and for the case where the mass is neglected. We find that the heavy flavor mass effects can give sizable corrections to the predicted asymmetry.

Introduction: Computed Tomography (CT) urography is more accurate in detection of renal masses, urinary tract tumors, inflammatory lesion, calculi and other causes of urinary tract obstruction compared with intravenous urography. The standard single bolus MDCT Urography protocol comprises three to four phases, consists of non-contrast, corticomedullary, nephrographic and excretory phases. A major disadvantage is a high radiation dose, which is 8-10 times higher than an IVP examination. In comparison, an split-bolus, dual-phase technique scans the urinary system in the non-contrast and combined nephrographic-excretory phases. This study aimed to compare the total CT radiation dose of patient and image quality in standard MDCTU protocol and low dose MDCTU protocol. Methodology: In this hospital based prospective study total 100 patients (50 tests and 50 controls) were compared for radiation dose and subjective image quality assessment between standard dose MDCTU protocol [non contrast scan at 120kvp , followed by contrast enhanced corticomedullary phase and excretory phase] and low dose MDCTU protocol (non contrast scan (at 80 kvp), followed by contrast enhanced synchronus corticomedullary phase and excretory phase acquisition by using split bolus contrast administration technique) . Result: In the standard dose MDCTU protocol in unenhanced and enhanced phase, patients received mean net effective dose of 18.83 mSv and in the low dose protocol, patients received mean net effective dose of 9.06 mSv with significant 52% dose reduction (P value <0.001). In Standard dose protocol in unenhanced phase, optimal resolution in 82% patients, moderately grainy/poor resolution in 14% and significantly grainy/very poor resolution in 4% patients. In low dose protocol, optimal resolution in 64% patients, mild to moderately grainy/poor resolution in 22% and significantly grainy/very poor resolution in 14% patients with no significant difference in image quality in both protocol (P value>0.05). In low dose protocol, mild to moderately grainy/poor resolution images (22%) of unenhanced phase reviewed together with normal dose good qualitysynchronus corticomedullary and excretory phase images to diagnosis the almost same spectrum of pathology like standard dose protocol. Conclusion: In low dose MDCT Urography radiation dose reduction of approx 50% is possible with no significant difference in image quality in line to ALARA principle (As low as reasonably achievable), facilitating diagnosis of urological pathologies.
BUDDHIST PHILOSOPHY AND ITS RELEVANCE IN DIGITAL AGE

Published: July 2022

How fast the digitalization is affecting all corners of our life and where does it leave our philosophical, ethical aspirations and cherish the ideals of democratic world, equality, privacy protection, trust and societal autonomy is a matter of social concern. Epistemologically we do understand and grasp the phenomenon,the new mediations, and the very fabric of the new processes. Buddha Dharma encompasses to balance between human life and ecology. Though the Buddhism is an ancient wisdom, the core principles and practice can solve the contemporary social, ethical, human problems and crises caused by the intensity of the digital delusion. Mahayana Buddhism believes that this world is constituted by emptiness,everything is in its becoming, which is dependent on everything else following the law of cause and effect. Buddhism advocates practicing meditation and attain wisdom to get rid of hatred, craving and delusion which are origins of Dukha. Knowing the four noble truths in depth and following the Ariya AstangaMarga, and practice of panchasila to get rid of craving, hatred and delusion which finally leads to Nirvana is the core philosophy of Buddhism.

Background: Denture adhesives are used to improve retention, stability, and efficiency of complete dentures. Proper use of denture adhesives has benefits for patients. Evaluating the effect of denture adhesives on efficiency of complete dentures in patients with different alveolar ridges among Kashmir population was the purpose of this study. Materials and Methods: This randomized clinical trials study was conducted on 40 patients who were wearing well fitted complete dentures. The patients were categorized intothree groups based on clinical and radiographic situations of residual ridges. Group I with mildresorption, Group II with moderate resorption, and Group III with severe resorption. The patients who had recently received their dentures and the primary complications had been resolved wereasked to use denture adhesive according to the instructions. The patients answered two differentquestioners in 1 week and 2 months of using denture adhesive. The answers were analyzed bymeans of variance and Chi square tests (P < 0.05). Results: Retention, chewing, talking, selfconfidence, and efficiency of dentures were improved in all patients. No statistical significant differences in these parameters were observed between thethree groups (P > 0.05). Increased retention and adaptation made 64.4% of these patients willing to continue using the adhesive after the study. Fortythree percent of patients reported moderatesatisfaction of using this adhesive. Conclusion: Using denture adhesive in well fitted complete dentures resulted in an improvement in retention, talking, chewing, ease of use, selfconfidence, and efficiency of dentures. The use of denture adhesive is, therefore, recommended to patients wearing dentures with some problems.
