Detection and classification of three-qubit states using l_1 norm of coherence
Authors: Kumari Anu , Adhikari Satyabrata
Published: June 2023

Entanglement is a purely quantum mechanical phenomenon and thus it has no classical analog. On the other hand, coherence is a well-known phenomenon in classical optics and in quantum mechanics. Recent research shows that quantum coherence may act as a useful resource in quantum information theory. We will employ here quantum coherence to detect and classify the entanglement property of three-qubit states. Moreover, we have shown that if any three-qubit state violates another necessary condition for the detection of a general biseparable state then the given three-qubit state cannot be a biseparable state. Since there are only three categories of states for the three-qubit system so if we detect that the state under probe is neither a separable nor a biseparable state then we can definitely conclude that the given three-qubit state is a genuine entangled state. We have illustrated our results with a few examples.
New entanglement-assisted quantum MDS codes derived from cyclic codes
Authors: Huang Sujuan , Zhu Shixin , Wang Pan
Published: June 2023

Entanglement-assisted quantum error-correcting codes, which can be seen as a generalization of quantum error-correcting codes, can be constructed from arbitrary classical linear codes by relaxing the self-orthogonality properties and using pre-shared entangled states between the sender and the receiver, and can also improve the performance of quantum error-correcting codes. In this paper, we construct some families of entanglement-assisted quantum maximum-distance-separable codes with parameters $[[\frac{{{q^2} - 1}}{a},\frac{{{q^2} - 1}}{a} - 2d+2 + c,d;c]]_q$, where $q$ is a prime power with the form $q = am \pm \ell$, $a = \frac{{\ell^2} - 1}{3}$ is an odd integer, $\ell \equiv 2\ (\bmod\ 6)$ or $\ell \equiv 4\ (\bmod\ 6)$, and $m$ is a positive integer. Most of these codes are new in the sense that their parameters are not covered by the codes available in the literature.
State support measures for import substitution impact on the investment projects efficiency in the power industry
Authors: Tregubova E. A. , Tregubov A. I.
Published: June 2023

In the structure of thermal generation of the Russian Federation, the share of modern combined-cycle plants, characterized by low specific fuel consumption (CCGT), is only 16 % and is based on the use of Western-made gas turbines. To stimulate import substitution, as measures of state support, special prices for capacity produced by new generation are used, and tax incentives are provided to investor enterprises. The paper assesses the impact of existing state support measures on the commercial efficiency of the investment project for the construction of a CCGT-120 on Russian equipment in the city of Saki (Republic of Crimea). The indicators of net present value (NPV), internal rate of return (IRR) and payback period for three scenarios (basic and two alternative, differing in the composition of state support measures) are considered. It is shown that the use of a special capacity tariff for new generation (competitive capacity extraction of new generating facilities – KOM NG) and tax incentives ensures the project’s profitability at the level of 18.7 % and the payback period is 7 years. Refusal to provide special tariffs for the capacity will cause the project to become unprofitable. The abolition of tax incentives will lead to a reduction in NPV by 40 %, a decrease in the project’s profitability to a critical level of 14.7 % and an increase in the payback period by 2 years. In order to rise the commercial efficiency of investment projects for the installation of CCGT units on Russian equipment and reduce the scale of their state support, it is necessary to increase the volume of heat supply and optimize investment costs.
Socio-psychological portrait of a modern teenager (sociological survey analysis)
Authors: Titor S. E.
Published: June 2023

Adolescence is traditionally attributed to the period of life from 11–12 to 14–15 years. The main contradiction of adolescence is that a teenager wants to be an adult, wants others to treat him as an adult, however, he himself does not feel genuine adulthood. These problems are often provoked by negative information from the internet environment. As part of the study of destructive information environment impact on minors, a sociological study was conducted. It was conducted by anonymous survey of adolescents of various social groups. According to the results of a sociological survey, the author drew a portrait of a modern teenager, identified the problems of the external environment in which he (she) is brought up.

Published: June 2023

In the context of the digitalization of the economy, it is important to systematize indicators that will fully assess the work of the regions of the Russian Federation in the direction of the country’s information development. The article presents a system for assessing state entities within the framework of infrastructure and access to the Internet network throughout the country. The authors analyze the heterogeneity of the regional structure of Russia in terms of digitalization indicators. The use of advanced statistical parametric and non-parametric methods made it possible to determine the stratification of regions. The paper compares the level of development of information and communication technologies in groups (layers) of regions according to the indicators included in the block “information and communication technologies infrastructure and access”, obtained as a result of monitoring the development of the information society in the Russian Federation. Researchers conduct a factor analysis to identify the main components that affect the level of development of information and communication technologies in the Russian regions.
Methodological approach to establishing incentives and readiness for labor migration of the digital generation – youth students
Authors: Apenko S. N. , Lukash A. V.
Published: June 2023

The relevance of youth students’ incentives and readiness for labor migration study is related to the challenges in the regional labor markets of the Russian Federation. The aim is to substantiate the approach for the study of the incentives and readiness for labor migration of the digital generation. To develop the methodological approach neoclassical migration theory, principles of new economic theory, migration model of E. Lee are taken. The system model is developed considering D. Tapscott’s network generation concept and SberCIB Investment Research analytics of Generation Z consumer practices. As a result, a systematic model of digital generation stimuli and readiness for labor migration research in the context of educational strategies and work experience is presented. The approach allows, firstly, to establish educational strategies of student youth: career-oriented (I); status-oriented (II); psychological comfort and creativity (III); forced learning (IV); random choice (V). Secondly, to determine correlations between educational strategies and labor practices of young people. For this purpose it is proposed to single out following groups: working students (R); with work experience (O); not working and not planning (N); not working but planning (P). Thirdly, to determine incentives and identify readiness for labor migration for each of the groups.
Stereospecific Cu(I)-catalyzed C-O cross-coupling synthesis of acyclic 1,2-di- and trisubstituted vinylic ethers from alcohols and vinylic halides.
Authors: Pham San , Kim Taehee , McDonald Frank
Published: June 2023

We report a robust method catalyzed by CuI and trans-N,N'-dimethylcyclohexyldiamine, enabling single-step C-O bond cross-coupling between 1,2-di- and trisubstituted vinylic halides with a variety of functionalized alcohols, pro-ducing acyclic vinylic ethers. In contrast with previous reports, this stereospecific transformation selectively gives each of the (E)- and (Z)-vinylic ether products from the corresponding vinylic halide precursors. This method is compatible with carbohydrate-derived primary and secondary alcohols, and several other functional groups. The conditions are mild enough to reliably generate vinylic allylic ethers without promoting Claisen rearrangements.
Paired Site Characterization in Aluminosilicate Zeolites through Limited Alkylammonium Stability
Authors: Abdelrahman Omar , Lawal Ajibola
Published: June 2023

The spatial distribution of tetrahedrally coordinated aluminum incorporated into a mordenite framework inverse framework zeolite was investigated through the proton site-selective probe chemistry of alkylamine Hofmann elimination. Protons associated with paired Al sites were exclusively exchanged with divalent cobalt, while isolated protons remained intact and readily quantified through Hofmann elimination of adsorbed alkylammonium species. Through a combination of temperature-programmed methods and spectroscopic characterization, the stability of the adsorbed alkylammonium was found to be crucial to the accurate estimation of isolated protons. Only alkylammonium species undergoing Hofmann elimination through a primary carbocation were found to exclusively probe isolated protons on the surface of cobalt-exchanged ZSM-5. More stable secondary and tertiary carbocations typically used in the characterization of acid sites, resulted in significant overestimates of protonic site densities. The result is contrary to purely protonic zeolites, where alkylammonium stability is inconsequential to the quantification of the acid sites they are coordinated with. Consequently, n-propylamine was found to be a suitable reactive probe molecule for the quantification of isolated protonic sites on divalent metal-cation zeolite surfaces, forming n-propylammonium upon adsorption. Ensuring accurate probing of isolated protons on the surface of metal cation exchanged zeolites was also demonstrated to require control of ion-exchange conditions and sufficient extent of zeolite exposure to the adsorbing n-propylamine. The fraction of paired Al sites in ZSM-5 was measured to systematically increase with Al content, ranging between 6 and 63 % across a Si/Al of 140 and 11.5, respectively. Experimentally measured Al pairing was in excellent quantitative agreement with a binomial distribution, suggesting a random incorporation of Al into the tetrahedral sites of ZSM-5 at next-nearest-neighboring positions.

Is it the End of the Ice Age?
Authors: Kwiecien Susan Y
Published: June 2023

The use of the RICE (Rest, Ice, Compression, Elevation) protocol has been the preferred method of treatment for acute musculoskeletal injuries for decades. However, the efficacy of using ice as a recovery strategy following injury in humans remains uncertain, and there is a growing trend recommending against icing following injury. Animal models suggest that while ice can help to accelerate the recovery process, extreme muscle cooling might delay repair and increase muscle scarring. Despite the conflicting evidence, ice should not be dismissed as a potential treatment option. When considering what is known about the injury cascade, the optimal application window for ice is in the immediate acute stage following injury to reduce the proliferation of secondary tissue damage that occurs in the hours after the initial injury. Practitioners should tailor the application of ice based on the injury timeline and repair process, consistent with applications in 20-30 minute intervals within the first 12 hours post-injury. Until the evidence unanimously proves otherwise, the culture of icing injuries should remain a staple in sports medicine.

Published: June 2023

Background and Purpose

The Expanded Cutting Alignment Scoring Tool (E-CAST) is a two-dimensional qualitative scoring system that has demonstrated moderate inter-rater and good intra-rater reliability for the assessment of trunk and lower extremity alignment during a 45-degree sidestep cut. The primary purpose of this study was to examine the reliability of the quantitative version of the E-CAST among physical therapists and to compare the reliability of the quantitative E-CAST to the original qualitative E-CAST. The hypothesis was that the quantitative version of the E-CAST would demonstrate greater inter-rater and intra-rater reliability compared to the qualitative E-CAST.

Study Design

Observational cohort, repeated measures reliability study

Methods

Twenty-five healthy female athletes (age 13.8±1.4 years) performed three sidestep cuts with two-dimensional video capturing frontal and sagittal views. Two physical therapist raters independently scored a single trial using both views on two separate occasions. Based on the E-CAST criteria, select kinematic measurements were extracted using a motion analysis phone application. Intraclass correlation coefficients and 95% confident intervals were calculated for the total score, and kappa coefficients were calculated per kinematic variable. Correlations were converted to z-scores and compared to the six original criteria for significance (α<0.05).

Results

Cumulative intra- and inter-rater reliability were both good (ICC=0.821, 95% CI 0.687-0.898 and ICC=0.752, 95% CI 0.565-0.859). Cumulative intra-rater kappa coefficients ranged from moderate to almost perfect, and cumulative inter-rater kappa coefficients ranged from slight to good. No significant differences were observed between the quantitative and qualitative criteria for either inter- or intra-rater reliability (Zobs(intra)= -0.38, p=0.352 and Zobs(inter)= -0.30, p=0.382).

Conclusion

The quantitative E-CAST is a reliable tool to assess trunk and lower extremity alignment during a 45-degree sidestep cut. No significant differences were observed in reliability of the quantitative versus qualitative assessment.

Effect of a Balance Adjustment System on Postural Control in Patients with Chronic Ankle Instability
Authors: Yoshida Kazushi , Kuramochi Rieko , Shinohara Junji
Published: June 2023

Background/Purpose

This study aimed to evaluate how a two-week program using the in-phase mode of a balance adjustment system (the BASYS) affected postural control in participants with chronic ankle instability (CAI). It was hypothesized that the in-phase mode on the BASYS would lead to improved postural control compared with training on a balance disc.

Study Design

Randomized control trial.

Methods

Twenty participants with CAI were recruited. The participants were divided into two intervention groups: the BASYS (n = 10) and Balance Disc (BD; cushion type, n = 10). All participants underwent six supervised training sessions over a two-week period. Static postural control during single leg standing with closed eyes was assessed for the CAI limb. We collected COP data while participants balanced on the BASYS. The test was performed for 30 sec, and the total trajectory length and 95% ellipse area were calculated. In the assessment of dynamic postural stability, Y-Balance tests-anterior, posteromedial, and posterolateral directions were measured on the CAI limb for all participants and normalized to the individual’s leg length. Participants were recorded at three instances: pretraining (Pre), post-training 1 (Post1: after the first training), and post-training 2 (Post2: after the last training).

Results

There was an effect on time in the COP total trajectory length of the BASYS group, which was significantly decreased for Post 1 and Post 2 than for the Pre (p = 0.001, 0.0001). Group differences and time-by-group interactions were not observed for either of the Y-balance test reach distances.

Conclusions

The study’s primary finding was that two weeks of intervention in the in-phase mode on the BASYS improved static postural control in participants with CAI.

Isokinetic Assessment of Knee Flexor and Extensor Strength and Lower Extremity Flexibility Assessment of an NCAA Division III Men’s Soccer Team
Authors: Perkins Savanna , Canavan Paul
Published: June 2023

Background

Strength imbalances and flexibility deficits of the hamstrings and hip flexors have been identified as potential risk factors for hamstring injuries, but research on athletes at the Division III level are limited, potentially due to a lack of resources and technology.

Purpose

The purpose of this study was to conduct isokinetic and flexibility assessments to screen male soccer athletes at risk of sustaining a hamstring injury.

Study Design

Observational cohort

Methods

Standardized isokinetic testing of concentric muscle performance, measured by peak torque of the quadriceps and hamstrings and hamstring-to-quadriceps ratios, was conducted using a Biodex isokinetic dynamometer at speeds of 60 and 180°/sec. Additionally, the Active Knee Extension (AKE) test and the Thomas test were performed bilaterally to objectively measure flexibility. Paired sample t-tests were used to compare left and right lower extremities for all outcomes, with the level of significance set at p<0.05. Participants were ranked for risk and given a set of exercises sourced from the FIFA 11 Injury Prevention Program.

Results

At 60°/sec, the mean PT/BW bilateral deficit was 14.1% for extension and 12.9% for flexion. At 180°/sec, the mean deficit was 9.9% for extension and 11.4% for flexion. The team’s average for left and right H:Q ratios for each speed were 54.4 and 51.4 at 60°/sec and 61.6 and 63.1 at 180°/sec, respectively. The team’s average AKE range of motion was 158° for the left leg and 160° for the right leg. The mean Thomas test measurements were 3.6° away from the neutral position on the right and 1.6° on the left, with nine positive tests. There were no statistically significant differences between left and right knee extension or flexion PT/BW or H:Q ratios at either speed. There was no significant difference between left and right AKE measurements (p=0.182).

Conclusion

The results of this screening suggest that isokinetic testing and flexibility testing may be useful to identify non-optimal strength ratios and flexibility deficits in male collegiate soccer players. The benefits of this research have direct implications, as participants received both their screening data and a set of exercises aimed to help decrease their injury risk, in addition to the offering data that is useful for determining what normative values for flexibility and strength profiles might look like for Division III male soccer players.

The Golfer’s Fore, Fore +, and Advanced Fore + Exercise Program: An Exercise Series and Injury Prevention Program for the Golfer
Authors: Thomas Zachary M , Wilk Kevin E
Published: June 2023

Golf is increasing in popularity with 24.8 million golfers in the U.S. in 2020, a 2% increase from the previous year. This number increased to 37.5 million in 2021 which can be further broken down to 25.1 million on course and 12.4 million participating in off course activities. Playing golf does not come without risk of injury, with an annual incidence between 15.8% and 40.9% in amateurs and 31% in professional golfers. Most injuries in golf occur due to overuse (82.6%) and only a small percentage occur from a single traumatic event (17.4%). Injuries most commonly occur at the low back followed by the wrist. Injury prevention programs have shown to be successful in other sports however to date there are no studies assessing a golfer’s specific program. The purpose of this clinical commentary is to describe three individualized and unsupervised golf exercise programs (The Golfer’s Fore, Fore+, and Advanced Fore+), of varying difficultly, designed to reduce the risk of injury, improve strength/mobility, and optimize performance.

Evaluation of the Back-in-Action test Battery In Uninjured High School American Football Players
Authors: Rohde Marcel , Ruhlemann Alina , Busch Andre , Grunwald Ulrich , Jaeger Marcus , Mayer Constantin
Published: June 2023

Background

Return to sport testing is an established routine, especially for athletes who have ruptured their anterior cruciate ligament (ACL). Various tests are performed, often combined in test batteries, such as the Back-in-action (BIA) test battery. Unfortunately, pre-injury performance is often unknown, and only few athletes pass the high demands of these test batteries.

Purpose

The aim of the study was to determine the performance of under 18 American football players on the BIA to establish pre-injury sport specific benchmarks for future RTS testing and to compare these values to data from an age-matched reference group.

Methods

Fifty-three healthy male American football players underwent a functional assessment using the “Back-in-action” test battery evaluating agility, speed (Parkour-Jumps and Quick-Feet test), balance (using a PC based balance board), and power (Counter-Movement-Jump [CMJ]) as objective measures. Their results were compared with a previously tested reference group (RP) and within the american football players (AF) through three subgroups according to field playing position.

Results

Overall, the American football (AF) athletes showed lower balance scores for both legs (AF: 3.71/3.57/3.61; RP: 3.4/3.2/3.2; p<0.002) compared to the reference population (RP). CMJ height and Quick-Feet results were not statistically different (p>0.05), Parkour-Jump times (AF: 8.18/ 8.13 sec.; RP: 5.9/5.9sec.; p<0.001) were significantly slower. Power output in all CMJ’s (AF: 46.86/36.94/37.36 W/kg; RP: 43.2/29.5/29 W/kg; p<0.001) was significantly higher than the RP. Passing and running game involved players (G2 & G3) showed significantly better balance scores (G2+G3: 3.36/3.27/3.33; G1: 4.22/4.06/4.10; p<0.001), higher jump height (G2&G3: 38.87/24.02/24.96 cm; G1: 32.03/19.50/18.96 cm; p<0.001) and more watts/kg (G2&G3: 48.83/37.21/37.64 W/kg; G1: 43.95/36.88/36.53 W/kg; p<0.001) compared to blocking players like Linemen (G1) and to the age matched reference population (RP).

Conclusion

Only 53% of the healthy athletes would have been cleared for sport using the BIA test criteria, which highlights the challenging passing criteria. Despite significantly greater power measurements, scores of balance and agility were poorer compared to the reference group, especially for linemen. These data may serve as sport and position specific reference for high school American football players, instead of using the non-specific reference group data.

Altered Knee Loading Following Primary ACL Repair versus ACL Reconstruction
Authors: Singleton Steven , Scofield Harrison , Davis Brittany , Waller Alexandra , Garrison Craig , Goto Shiho , Hannon Joseph
Published: June 2023

Background

ACL repair (ACL-r) has recently gained renewed clinical interest for treatment of ACL tears. ACL-r has several potential benefits over ACL reconstruction (ACL-R) including maintaining the native ACL innervation and blood supply, no graft site morbidity, and possible improved knee biomechanics and decrease in osteoarthritis. The purpose of this study was to assess for differences in metrics of knee joint loading during a single limb squat task between individuals following a primary ACL-r versus those who underwent a standard ACL-R with a patella bone-tendon-bone autograft.

Study type

Case Control Study

Methods

The ACL-r group [n: 15, age(yrs): 38.8±13.9] sustained a proximal ACL disruption that was amenable to repair, while the ACL-R group [n: 15, age(yrs): 25.60±1.7] underwent primary reconstruction with patella bone-tendon-bone autograft. At 12-weeks post-operation, both groups completed the IKDC questionnaire and biomechanical testing during performance of the single limb squat. Bilateral peak knee extension moment and total knee joint power as a measure of eccentric loading (contraction) during the descent phase of the squat were calculated on the surgical and non-surgical limb and averaged across the middle three of five trials. Participants also completed quadriceps strength testing on both limbs three months after surgery on an isokinetic dynamometer at 60°/sec. LSI (Limb Strength Index) was calculated for all variables. Separate ANCOVAs were performed on each biomechanical variable to examine differences between groups.

Results

The ACL-r had a significantly greater peak knee extension moment LSI (ACL-r: 78.46±5.79%; ACL-R: 56.86±5.79%; p=0.019, ηp2=.186) and total knee joint power LSI (ACL-r: 72.47±7.39%; ACL-R: 39.70±7.39%, p=0.006, ηp2=.245) than the ACL-R group. The ACL-r also had a significantly greater quadriceps LSI than the ACL-R group (ACL-r: 66.318±4.61%, ACL-R: 48.03±4.61%, p=0.013, ηp2=.206).

Conclusions

Using MSK Ultrasound in the Evaluation of Subscapularis Injuries
Authors: Manske Robert C. , Voight Michael , Wolfe Chris , Page Phil
Published: June 2023

The shoulder is an area that can be prone to a variety of injuries, including subscapularis tendon tears. The subscapularis muscle is one of the four muscles that make up the rotator cuff in the shoulder and plays an essential role in stabilizing the shoulder joint while at the same time facilitating internal rotation of the humerus. Injuries to the subscapularis can occur due to trauma, overuse, or degeneration, leading to pain, weakness, and limited mobility. When injury occurs, subscapularis tendon tears are often difficult to diagnose and evaluate due to their location deep within the shoulder joint. While traditional imaging techniques like radiographs, and magnetic resonance imaging may give us insight into the structures present, they do not always provide detailed enough information for clinicians. Ultrasound has become increasingly popular in musculoskeletal (MSK) rehabilitation as it allows for direct visualization of soft tissue abnormalities like tendinopathies or subtle rotator cuff tear patterns. In this Ultrasound Bites article, we will discuss how MSK ultrasound can be used in the evaluation of subscapularis tendon pathology with a specific focus on its utility in the physical therapy clinic.

Published: June 2023

Rehabilitation after knee cartilage repair or restoration can be a challenging and nuanced process. Historically, conservative rehabilitation protocols have been characterized by limited weightbearing and restricted range of motion (ROM) were created to primarily protect the repaired cartilage but did little for progression into higher level activity. Recent literature has supported accelerated protocols in a variety of cartilage procedures ranging from osteochondral allograft (OCA) Osteochondral autograft surgery (OATS) to matrix-based scaffolding procedures such as Matrix Induced Chondrocyte Implantation (MACI) or Denovo procedures. Advances in technology such as blood flow restriction (BFR) and testing equipment with progressive rehabilitation from the acute phase through the return to sport continuum have made it possible to return to a higher level of activity and performance than first thought of for these procedures. This clinical viewpoint discusses the evolution of knee cartilage rehabilitation characterized by early but progressive weightbearing and early ROM while maintaining early homeostasis in the knee, and then its progression to return to sport and performance in the higher-level athlete.
