A safe percutaneous technique for the reduction of irreducible femoral neck fractures using ultrasound localization of the femoral vascular and nervous structures at the hip

Abstract We present a safe percutaneous technique for the placement of Kirschner wires into the femoral head to assist in the reduction of irreducible femoral neck fractures using ultrasound to identify the vascular and nervous structures about the hip. From January 2011 to June 2014, a total of 36 patients (25 males and 11 females) were enrolled in this study. Patients were placed on a fracture reduction table for limb traction. After 3 unsuccessful reductions with limb traction, ultrasound-guided localization of the patient's femoral artery, vein, and nerve at the hip was performed. These structures were marked on the overlying skin and then Kirschner wires were inserted into the femoral head avoiding these marked structures. After the surgery, the Kirschner wire insertions were routinely reviewed by ultrasound, the hip fracture reduction and the femoral nerve sensorimotor function were routinely examined as well. All 36 patients with an irreducible variant of a femoral neck fracture showed anatomic reduction under C-arm fluoroscopy using ultrasound to avoid K wire injury to the femoral vascular structures and nerve. No major vascular injury during operation. In post-surgical ultrasound examination, local hematoma formation was not evident. There was normal function of the femoral nerve. On follow-up, there were no infections, wound problems, recurrence of fracture displacement, laxity, or implant breakage. Preoperative ultrasonic localization of the femoral artery, vein, and femoral nerve safely allowed. Kirschner wire placement under C-arm fluoroscopy into the femoral head to assist in fracture reduction. This assisted reduction method for irreducible femoral neck fractures had a number of advantages, including closed anatomic reduction with minimal attempts, used simple equipment, and avoided further destruction of the blood supply to the femoral head.
General Principles to Justify Plant Biostimulant Claims

The forthcoming European Union (EU) Fertilizing Products Regulation1 proposes a claim-based definition of plant biostimulants, stipulating that “plant biostimulant” means a product stimulating plant nutrition processes independently of the product’s nutrient content, with the aim of improving one or more of the following characteristics of the plant: nutrient use efficiency, tolerance to abiotic stress, crop quality traits or availability of confined nutrients in the soil and rhizosphere. The future regulation also specifies that a plant biostimulant “shall have the effects that are claimed on the label for the plants specified thereon. ” This creates an onus for manufacturers to demonstrate to regulators and customers that product claims are justified. Consequently, the justification of the agronomic claim of a given plant biostimulant will be an important element to allow it to be placed on the EU market once this new European regulation is applied. In this article, members of the European Biostimulant Industry Council (EBIC) propose some general guiding principles to follow when justifying plant biostimulant claims, that are outlined in this article. These principles are expected to be incorporated into harmonized European standards that are being developed by the European Committee for Standardization (CEN) to support the implementation of the regulation.
Factors Associated with Vitamin D Deficiency Among Adolescents in the Korea

The purpose of this research is to understand the factors related to the vitamin D deficiency. This research secondarily analyzed the raw data of ‘the 6 th Korean National Health and Nutrition Examination Surveys (2013~2014)’, which had been investigated by the Korea Centers for Disease Control and Prevention. There had been a total of 561 subjects. The data were analyzed with the t-test, the χ-test, and the logistic regression analysis. The results of the research were the regarding the vitamin D deficiency of the youths, the prevalence rate was higher the older the age (p=.041). And in the case of having engaged in the walking exercises (p=.011), the prevalence rate was low. In this research, it was able to confirm that the age and the walking exercise are the related factors of the vitamin D deficiency of the youths. As a result, in order to alleviate the vitamin D deficiency of the junior high school students, the nursing intervention and the development of the educational program that consider the above variables and the verification of their effects is demanded.
Ao2I: Minimizing Age of Outdated Information to Improve Freshness in Data Collection

Recently, it has been recognized that there is a serious limitation with the original Age of Information (AoI) metric in terms of quantifying true freshness of information content. A new metric, called Age of Incorrect Information (AoII), has been proposed. By further refining this new metric with practical considerations, we introduce Age of Outdated Information (Ao2I) metric. In this paper, we investigate a scheduling problem for minimizing Ao2I in an IoT data collection network. We derive a theoretical lower bound for the minimum Ao2I that any scheduler can achieve. Then we present Heh—a low-complexity online scheduler. The design of Heh is based on the estimation of a novel offline scheduling priority metric in the absence of knowledge of the future. We prove that at each time, transmitting one source with the largest offline scheduling priority metric minimizes Ao2I. Through extensive simulations, we show that the lower bound is very tight and that the Ao2I obtained by Heh is close-to-optimal.
Auditory Event-Related Potentials in Antipsychotic-Free Subjects With Ultra-High-Risk State and First-Episode Psychosis

Background: Auditory event-related potentials (ERPs) have been utilized to study defective information processing of patients with schizophrenia. To delineate the pathophysiological processes from pre-psychotic state to first-episode psychosis, a study on subjects from ultra-high-risk (UHR) state to first-episode psychosis, ideally in an antipsychotic-free condition, can add important information to our understanding. Methods: Patients with UHR state or at their first-episode psychosis (FEP) who were drug-naive or only have been temporarily treated with antipsychotics were assessed by auditory ERPs measurement, including P50/N100 (sensory gating) and duration mismatch negativity (MMN; deviance detection). A group of age-matched healthy subjects served as their controls. Results: A total of 42 patients (23 UHR and 19 FEP) and 120 control subjects were recruited, including 21 pure drug-naive and 21 with very short exposure to antipsychotics. Collapsing FEP and UHR as a patient group, they exhibited significant sensory deficits manifested as larger P50 S2 amplitude, larger N100 ratio, and smaller N100 difference, and significantly less deviance detection response revealed by MMN. Such differences were less significant when treating FEP and UHR separately for comparisons. Comparisons of ERP results between drug-naive subjects and antipsychotic-short-exposure subjects revealed no significant difference in any P50/N100 and MMN parameter. Conclusion: Our study is one of the few studies focused on drug-naive or minimally treated patients at pre- or early-psychotic states. Our results exhibited impaired performance in sensory gating and deviance detection shown by certain parameters. A longitudinal study with larger sample sizes will be helpful to provide more evidence to elucidate the role of antipsychotics on an individual’s neurophysiological performance at different stages of psychosis.
Attacking Tumors From All Sides: Personalized Multiplex Vaccines to Tackle Intratumor Heterogeneity

Tumor vaccines are an important asset in the field of cancer immunotherapy. Whether prophylactic or therapeutic, these vaccines aim to enhance the T cell-mediated anti-tumor immune response that is orchestrated by dendritic cells. Although promising preclinical and early-stage clinical results have been obtained, large-scale clinical implementation of cancer vaccination is stagnating due to poor clinical response. The challenges of clinical efficacy of tumor vaccines can be mainly attributed to tumor induced immunosuppression and poor immunogenicity of the chosen tumor antigens. Recently, intratumor heterogeneity and the relation with tumor-specific neoantigen clonality were put in the equation.In this perspective we provide an overview of recent studies showing how personalized tumor vaccines containing multiple neoantigens can broaden and enhance the anti-tumor immune response. Furthermore, we summarize advances in the understanding of the intratumor mutational landscape containing different tumor cell subclones and the temporal and spatial diversity of neoantigen presentation and burden, and the relation between these factors with respect to tumor immunogenicity. Together, the presented knowledge calls for the investment in the characterization of neoantigens in the context of intratumor heterogeneity to improve clinical efficacy of personalized tumor vaccines.
Exploring Problems in Teaching and Learning Grammar in EFL Context: A Review Paper

This review paper is aimed at exploring problems EFL teachers are facing when teaching and learning the English grammar in the EFL context. Initially, we have critically discussed the importance of teaching and learning grammar and types of grammar teaching. Further, the challenges and obstacles in teaching and learning the grammar, and significant problems that EFL teacher isencountered with their daily life have also been explored with details. The data has been collected from the most reliable online resources such, Elsevier, Willey, Science Direct, Research Gate, Academia, Google Scholar, and SemanticScholar. After collecting data for the title, then we have screened the most significant publications and articles that best supported the title of this research, and later discussed critically. The result of the review revealed that teaching grammar is the essential requirement of learning any foreign language. The legendary types of grammar indicated in this study aredescriptive grammar, prescriptive grammar, and universal grammar, functional grammar, and structural grammar, explicit and implicit instruction.Besides, the most challenging problems within instructing and teaching English grammar in EFL context are the lack of encouragement, teaching and learning have historically been dominated by the grammar-translation process, where the mother tongue of the learners have been used widely. Teaching through Implicit/explicit way instruction, grammatical learning difficulties and linguistic features are problems in teaching and learning the English language. On the other hand, the prominent problems and challenges that EFL teachers are facing are teachers‟ beliefs in teaching grammar, problems of handling large classes, problems of handling mixed background classes, problems of time limitation, lack of linguistic knowledge, lack of a coherent theoretical underpinning for the place of grammar in the curriculum, Lack experience, lack of knowledge on understanding students‟ needs, Teachers‟ low proficiency levels, or their lack of confidence in their ability, and teacher‟ declination in recognizing and reconciling prescriptive and rhetorical conceptualizations of grammar.
On the Road Leading to Non-Suicidal Self-Injury : Brief report 3 as illustrated extensively in a review

Background: Recent empirical research showed that pathological narcissism is related to Non-Suicidal Self-Injury (NSSI). However, both narcissistic vulnerability and narcissistic grandiosity were resulted related to NSSI and the differences between them and their role in NSSI remains unclear. Some authors underlined the potential role of shame in the genesis of self-directed aggression. Objectives: This study investigates the role of shame in the relationship between both vulnerable and grandiose narcissism and self-harm severity. Methods: We administered Pathological Narcissism Inventory (PNI), Test of Self-Conscious Affect (TOSCA) and Deliberate Self Harm Inventory (DSHI) to a sample of 149 community participants (42% males) with a mean age of 27.55 years (SD=12.3). Results: Controlling for age and gender, we found that DSHI scores correlated significantly with the vulnerable dimension of narcissism but not with the grandiose one. But, both the vulnerable and grandiose dimension of narcissism correlated with interpersonal shame levels. Finally, we found a positive interaction between PNI vulnerable factor and shame levels in predicting Non-suicidal selfinjury (NSSI) severity. Conclusions: Differentiating the grandiose from the vulnerable facet of narcissism appears central when investigating the relationship between NSSI and narcissistic personality. Moreover, our study suggests that shame experiences have a remarkable influence importantly account for this relationship. Future directions and clinical implications are discussed. 1 Department of Dynamic, Clinical Psychology and Health Studies, Faculty of Medicine and Psychology, University of Rome Sapienza, Italy E-mail corresponding author: patrizia.velotti@uniroma1.it
BATCH ORDERING INVENTORY MANAGEMENT UNDER THE MIXED DEMAND INFORMATION: A CASE STUDY

This study is concerned with analysing the past demand data and development of an inventory model with demand arising from deterministic which is known in advance and random sources simultaneously. Two different shortages are created for each demand type and in order to prevent model to backlog the deterministic demand, very high shortage cost is given for deterministic demand. The numerical value of the parameters are obtained from a real case which the inventory system of an information and technological organization of a university. The main difference of this study from the previous studies is that the order amount must be in palette quantity for a deterministic and stochastic demand inventory problem. Under this constraint, an inventory model is developed and tested with several datasets. Assuming lead time as constant, the value of deterministic demand present in the system and impact of palette constraint are investigated. These investigations are compared with the status quo in the case study. It has seen that the palette quantity behaves as safety stock for high level random demand. Recommendations based on the impacts of advance demand information, lead time and pallet quantity are presented in terms of changing in ordering costs, holding costs and service level.

Rain fade margin of terrestrial line-of-sight (LOS) links for 5G networks in Peninsular Malaysia

Abstract Advanced telecommunication systems are moving toward a high data transfer rate and wider bandwidth. The 5G communication network has recently been implemented for such aims. However, 5G networks operating with high operating frequency (typically above 20 GHz) could lead to impairments because of the atmospheric phenomena mainly precipitation and especially heavy rain. To address this, an optimum rain fade margin for the 5G network in Peninsular Malaysia is proposed using 77 sites of the rain-gauge network, which convert 1-h rain data to 1-min rain data by means of the international telecommunication union recommendation (ITU-R) P.837-7 model. Long-term rain attenuation statistics are obtained from ITU-R P.530-17 and the synthetic storm technique. The predicted rain attenuation is also presented in monthly statistics and in rain attenuation contour maps. The analysis showed that at 99.99% of link availability, the optimum rain fade margin operating at 26 GHz link should be in the range of 6.50 to 10 dB and 7 to 11 dB at 28 GHz link for a 5G network. Such information is useful for network operators and system engineers for the operation of 5G terrestrial microwave links in heavy rain regions.
Decoherence dynamics of open qubit systems

The thesis is contributed to the study of the decoherence dynamics of dissipative qubit systems. We reveal the profound impact of the formation of a bound state between the qubit and its local environment on the decoherence dynamics of qubit system in non-Markovian regime. We find that the decoherence can be suppressed greatly under the non-Markovian dynamics when the bound state is formed. Consequently, the entanglement can be partially preserved in the steady state. A criterion on this decoherence/disentanglement suppression is given explicitly. It can give a useful guideline on the decoherence control in experiment. We also find that the entanglement can be stably distributed among all components and particularly it always satisfies an identity. Our unified treatment includes the previous results in the literatures as special cases. The result reveals the profound nature of the entanglement and should have significant implications for quantum information processing.

Containing Calcium Phosphates

methacrylate-based endodontic sealers containing α-tricalcium phosphate (α-TCP) or nanostructured hydroxyapatite (HAp). Experimental methacrylate-based dual-cure sealers with the addition of α-TCP or HAp, at 10%wt were formulated and compared to AH Plus (AHP). Cell viability was assessed by 3-(4,5-dimethyl-thiazoyl)-2,5-diphenyl-tetrazolium bromide (MTT), and sulforhodamine B (SRB). Sealers were implanted in rats’ subcutaneous tissue and histologically evaluated. Bioactivity was assessed by alkaline phosphatase enzyme activity (ALP) and Alizarin Red (AR), using apical papillary cells (SCAPs), and by the bone deposition measured in surgical cavities on rats’ femur filled with AH Plus or α-TCP. In both viability assays, HAp and AHP sealers were similar, and α-TCP presented lower viability compared to the others at MTT assay (p<0.05). A gradual decrease of the inflammatory response according to the periods was observed and AHP was the only that presented giant cells (7-day period). Collagen fibers condensation increased according to the periods, with no differences among sealers. There was an increase at ALP activity and mineralized nodules deposition according to periods. HAp and α-TCP presented higher values for ALP activity at 5 days and at 5, 10, and 15 days for AR and were different from AHP (p<0.05). α-TCP presented superior values at 10 and 15 days compared to HAp and AHP for AR (p<0.05). At 90 days, α-TCP and control (empty cavity) showed high bone deposition compared to AHP (p<0.05). α-TCP and HAp, in a methacrylate-based sealer, presented biocompatibility and bioactivity, with the potential to be used as endodontic sealers in clinical practice. Further investigations are required to gain information on the physicochemical properties of these sealers formulation before its clinical implementation.

2 Chapter 2 Effects of Fly Ash on Mechanical Properties of PC Girder Using Reactive Andesite Aggregates

In the Hokuriku region, alkali-silica reaction (ASR) caused severe degradations in many concrete bridges. However, criteria for repair and replacement works of these structures are still unclear. For the development of damage evaluation procedure, it is necessary to investigate the load-carrying capacity of prestressed concrete (PC) girders affected by ASR-induced deterioration in actuality. This study constructed two full-size PC specimens from the high-early-strength Portland cement and reactive aggregates, and then exposed them to outdoor environmental conditions. One of them was specially mixed with a controlled amount of fly ash. After one and a half years of outdoor exposure, destructive loading tests were carried out to investigate the difference in loading capacity of the girders. From results of the long-term exposure and the tests, the flexural strength and the rigidity of the specimen with fly ash were not degraded while ASR was also effectively suppressed. In addition, cylindrical concrete cores were taken at different positions of both girders to analyze the relationship between mechanical properties of concrete such as compressive strength, static elastic modulus, and ultrasonic wave propagation speed. Results of the coring test showed that the mechanical properties of concrete cores varied according to their collecting positions and directions.
