Published: February 2017

While the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides numerous benefits to many enrolled families across the United States, including access to nutritious foods, some recent drops in maternal participation in Kentucky resulted from failures to retrieve those benefits. We explored perceived benefits of and encountered barriers to food benefit retrieval. Journey mapping included direct observations of client appointments, clinic lobby areas, and a shopping experience and was augmented with focus groups conducted in two urban and two rural areas. Major touchpoints before WIC appointments, during those appointments at clinics, and after appointments when redeeming food benefits were identified. Across touchpoints, mothers identified childcare, transportation issues, long waits, confusion regarding eligibility, problems scheduling appointments, and stigma as barriers to their ability to retrieve food instruments. Despite these barriers mothers value the benefits of WIC, especially access to healthy foods, infant formula, and nutrition education. This work demonstrates a method by which WIC mothers’ experiences shed light on client service shortfalls and possible opportunities to improve client services.

Understanding socialbot behavior on end hosts
Authors: He Yukun , Li Qiang , Cao Jian , Ji Yuede , Guo Dong
Published: February 2017

Server-side socialbot detection approaches can identify malicious accounts and spams in online social networks. However, they cannot detect socialbot processes, residing on user hosts, which control these accounts. Therefore, new approaches are needed to detect socialbots on hosts. The fundamental to design host-side detecting approaches is to gain an insight into the behaviors of socialbots on host. In this article, we analyzed a series of representative socialbots in depth and summarized the typical features of socialbot behaviors. We proposed a new approach to defense against socialbots on end host. The contributions of this article are threefold: (1) our analysis approach can be used for reference during analyzing new socialbots in the future; (2) we provide several behavior features of socialbots on hosts, including network flow through which socialbots communicate with botmasters through the online social network, system calls via which socialbots conduct an activity, and process information of socialbots running on hosts. These features can be used by someone to design approaches to identifying socialbots on a host; (3) our proposed detection approach can effectively distinguish between a socialbot and a benign application on end hosts.
Anomalous Radial Artery as an Incidental Finding During a Routine Carpal Tunnel Release
Authors: Gober Charles A. , Mujadzic Tarik , Hershman John E. , Mujadzic Mirsad M.
Published: February 2017

Background: Compression of the median nerve at the wrist, or carpal tunnel syndrome, is the most commonly recognized nerve entrapment syndrome. Carpal tunnel syndrome is usually caused by compression of the median nerve due to synovial swelling, tumor, or anomalous anatomical structure within the carpal tunnel. Methods: During a routine carpal tunnel decompression, a large vessel was identified within the carpal tunnel. Results: The large vessel was the radial artery. It ran along the radial aspect of the carpal tunnel just adjacent to the median nerve. Conclusions: The unusual presence of the radial artery within the carpal tunnel could be a contributing factor to the development of carpal tunnel syndrome. In this case, after surgical carpal tunnel release, all symptoms of carpal tunnel syndrome resolved.
Endarterectomy for a symptomatic carotid web
Authors: Phair John , Trestman Eric B , Yean Chetra , Lipsitz Evan C
Published: February 2017

Background

We report a symptomatic carotid web successfully treated with carotid endarterectomy. A healthy 43-year-old woman presented with acute-onset left-sided weakness. Carotid web was evident on computed tomography angiography as a focal filling defect in the right common carotid artery. This right common carotid artery web extended into the ICA created an eddy resulting in turbulent flow. Subsequent acute embolus formation led to embolization and acute stroke.

Method

Review of the literature was performed using Medline Plus and PubMed databases.

Result

The patient underwent carotid endarterectomy with primary closure. Procedure was well tolerated and there was an uneventful recovery.

Conclusion

Arterial webs are a rare arteriopathy and a usual arrangement of fibromuscular intralumenal in-growth with unclear etiology. It is however, an important potential etiology of stroke in patients without traditional atherosclerotic risk factors. Carotid web and atypical carotid fibromuscular dysplasia should be considered in young, otherwise healthy patients presenting with stroke and without the typical risk factors for atherosclerotic carotid disease and stroke.
Public health campaigns and their effect on stroke knowledge in a high-risk urban population: A five-year study
Authors: Metias Maged M , Eisenberg Naomi , Clemente Michael D , Wooster Elizabeth M , Dueck Andrew D , Wooster Douglas L , Roche-Nagle Graham
Published: February 2017

Background

The level of knowledge of stroke risk factors and stroke symptoms within a population may determine their ability to recognize and ultimately react to a stroke. Independent agencies have addressed this through extensive awareness campaigns. The aim of this study was to determine the change in baseline knowledge of stroke risk factors, symptoms, and source of stroke knowledge in a high-risk Toronto population between 2010 and 2015.

Methods

Questionnaires were distributed to adults presenting to cardiovascular clinics at the University of Toronto in Toronto, Canada. In 2010 and 2015, a total of 207 and 818 individuals, respectively, participated in the study. Participants were identified as stroke literate if they identified (1) at least one stroke risk factor and (2) at least one stroke symptom.

Results

A total of 198 (95.6%) and 791 (96.7%) participants, respectively, completed the questionnaire in 2010 and 2015. The most frequently identified risk factors for stroke in 2010 and 2015 were, respectively, smoking (58.1%) and hypertension (49.0%). The most common stroke symptom identified was trouble speaking (56.6%) in 2010 and weakness, numbness or paralysis (67.1%) in 2015. Approximately equal percentages of respondents were able to identify ≥1 risk factor (80.3% vs. 83.1%, p = 0.34) and ≥1 symptom (90.9% vs. 88.7%, p = 0.38). Overall, the proportion of respondents who were able to correctly list ≥1 stroke risk factors and stroke symptoms was similar in both groups.(76.8% vs. 75.5%, p = 0.70). The most commonly reported stroke information resource was television (61.1% vs. 67.6%, p = 0.09).

Conclusion

Stroke literacy has remained stable in this selected high-risk population despite large investments in public campaigns over recent years. However, the baseline remains high over the study period. Evaluation of previous campaigns and development of targeted advertisements using more commonly used media sources offer opportunities to enhance education.
Feature points selection with flocks of features constraint for visual simultaneous localization and mapping
Authors: Liu Hong , Wang Zhi , Chen Pengjin
Published: February 2017

Simultaneous localization and mapping is a crucial problem for mobile robots, which estimates the surrounding environment (the map) and, at the same time, computes the robot location in it. Most researchers working on simultaneous localization and mapping focus on localization accuracy. In visual simultaneous localization and mapping , localization is to calculate the robot’s position relative to the landmarks, which corresponds to the feature points in images. Therefore, feature points are of importance to localization accuracy and should be selected carefully. This article proposes a feature point selection method to improve the localization accuracy. First, theoretical and numerical analyses are conducted to demonstrate the importance of distribution of feature points. Then, an algorithm using flocks of features is proposed to select feature points. Experimental results show that the proposed flocks of features selector implemented in visual simultaneous localization and mapping enhances the accuracy of both localization and mapping, verifying the necessity of feature point selection.
We know they train, but what do they do? Implications for coaches working with adolescent rugby union players

Published: February 2017

Limited information is available regarding the training loads of adolescent rugby union players. One-hundred and seventy male players (age 16.1 ± 1.0 years) were recruited from 10 teams representing two age categories (under-16 and under-18) and three playing standards (school, club and academy). Global positioning systems, accelerometers, heart rate and session-rating of perceived exertion (s-RPE) methods were used to quantify mean session training loads. Session demands differed between age categories and playing standards. Under-18 academy players were exposed to the highest session training loads in terms of s-RPE (236 ± 42 AU), total distance (4176 ± 433 m), high speed running (1270 ± 288 m) and PlayerLoad™ (424 ± 56 AU). Schools players had the lowest session training loads in both respective age categories. Training loads and intensities increased with age and playing standard. Individual monitoring of training load is key to enable coaches to maximise player development and minimise injury risk.

Authors: Macefield Rhiannon C , Reeves Barnaby C , Milne Thomas K , Nicholson Alexandra , Blencowe Natalie S , Calvert Melanie , Avery Kerry NL , Messenger David E , Bamford Richard , Pinkney Thomas D , Blazeby Jane M
Published: February 2017

Background:

Surgical site infections (SSIs) are the third most common hospital-associated infection and can lead to significant patient morbidity and healthcare costs. Identification of SSIs is key to surveillance and research but reliable assessment is challenging, particularly after hospital discharge when most SSIs present. Existing SSI measurement tools have limitations and their suitability for post-discharge surveillance is uncertain.

Aims:

This study aimed to develop a single measure to identify SSI after hospital discharge, suitable for patient or observer completion.

Methods:

A three-phase mixed methods study was undertaken: Phase 1, an analysis of existing tools and semi-structured interviews with patients and professionals to establish the content of the measure; Phase 2, development of questionnaire items suitable for patients and professionals; Phase 3, pre-testing the single measure to assess acceptability and understanding to both stakeholder groups. Interviews and pre-testing took place over 12 months in 2014–2015 with patients and professionals from five specialties recruited from two UK hospital Trusts.

Findings:

Analyses of existing tools and interviews identified 19 important domains for assessing SSIs. Domains were developed into provisional questionnaire items. Pre-testing and iterative revision resulted in a final version with 16 items that were understood and easily completed by patients and observers (healthcare professionals).

Conclusion:

A single patient and observer measure for post-discharge SSI assessment has been developed. Further testing of the validity, reliability and accuracy of the measure is underway.
School Nurse Evaluation

Published: February 2017

Evaluation of one’s school nurse practice is one standard in the school nurse’s scope and standards of professional practice. The Virginia School Nurse Institute Partnership (SNIP) identified the need to develop a concise self-evaluation tool that school nurses and their nurse and non-nurse employers could use to appropriately document a school nurse’s practice. The purpose of this article is to provide a self-evaluation tool that the school nurse and his or her employers can use to evaluate professional school nurse practice.
Historic Leadership
Authors: Johnsen Ellen F. , Pohlman Katherine J.
Published: February 2017

School nursing practice establishes itself in the midst of both education and nursing philosophies, ethics, standards, laws, and regulations. Treading these two worlds is difficult at times and requires that a school nurse possess a strong foundational knowledge base, seek professional collaboration, and navigate conflicting professional demands in order to promote student and public safety. This article is Part 2 of a four-part series that recounts the inspiring story of a school nurse, Ellen Johnsen, who did just that back in the 1980s in Broken Arrow, Oklahoma. Part 2 describes how Ellen’s actions led the Broken Arrow Public Schools to revise its unsafe and illegal medication administration policy, which brought the policy into partial compliance with the nurse practice act but culminated in Ellen losing her job. The purpose of this series is to enhance understanding of the legal parameters governing school nurse practice, provide examples of ethical decision making, and review the challenges associated with serving as a leader.
CT patterns of organizing pneumonia in patients treated with VEGF/mTOR inhibitors for metastatic renal cell cancer: an observational study
Authors: Dettmer Sabine , Grünwald Viktor , Fuehner Thomas , Ganser Arnold , Wacker Frank , Ivanyi Philipp , Rodt Thomas
Published: February 2017

Background

Targeted therapies are the standard treatment in patients with metastatic renal cell carcinoma (mRCC) and are known to cause adverse pulmonary events. Organizing pneumonia (OP) with its various manifestations in computed tomography (CT) has therefore lately received more attention.

Purpose

To describe the spectrum of CT patterns of OP in patients with mRCC receiving targeted therapies.

Material and Methods

Seventeen patients with known therapy-related OP were analyzed retrospectively by two blinded radiologists in consensus. Images were scored according to OP patterns that have previously been described. Additionally, the distribution and the predominant imaging pattern in each patient were determined.

Results

In our cohort, ground glass opacity was the most common imaging pattern (17/17, 100%) in patients with OP followed by a reticular pattern (12/17, 71%), consolidations (10/17, 59%), nodules (7/17, 41%), crazy paving (5/17, 29%), bronchi(ol)ectasis (4/17, 24%), focal mass (3/17, 18%), and reversed halo (1/17, 6%). The most common imaging pattern was changing multifocal consolidations (8/17, 47%). A bronchocentric and a nodular pattern were found in four patients (24%) each, a progressive fibrotic pattern in none patient, and reversed halo/atoll pattern in one (6%) case.

Conclusion

OP is the major differential diagnosis to be considered in patients with targeted therapies and pulmonary changes. Knowledge of the variety of imaging findings can facilitate diagnosis.
A randomized control trial to evaluate the effectiveness of intravenous, intra-articular and topical wash regimes of tranexamic acid in primary total knee arthroplasty
Authors: Prakash Jatin , Seon Jong-Keun , Park Yong Jin , Jin Cheng , Song Eun-Kyoo
Published: February 2017

Background:

The efficacy of tranexamic acid to decrease post-operative blood loss and blood transfusion is well established in literature. However, the ideal mode of administration is debatable. Limited literature has compared all the available modes of administration including intravenous (IV), topical irrigation and retrograde through drain. We hypothesized that no difference would be present in either form of administration of tranexamic acid.

Methods:

Fifty patients in four groups were enrolled for study. Group 1 received drug intravenously, group 2 had topical washing with drug before closure, group 3 received drug after closure through drain and group 4 was control that received no tranexamic acid. Post-operative blood loss, calculated blood loss, haemoglobin drop, transfusion requirements and complications were studied for all four groups.

Results:

Tranexamic acid results in lower bleeding irrespective of the mode of administration compared to control group. Total loss at end of 5 days is similar in all tranexamic acid groups irrespective of method used to deliver the drug. Calculated blood loss and haemoglobin drop was minimum for IV and in patients who were administered drug retrograde through drain. Requirement for blood transfusion was found to be lower in all tranexamic acid patients compared to non-tranexamic acid group. The requirement was highest in topical wash group among all tranexamic acid groups.

Conclusion:

We conclude that intra-articular administration through drain and IV administration are equally effective and superior to topical wash method in reducing blood loss, haemoglobin fall and transfusion requirements.
Oxygen therapy for interstitial lung disease: a systematic review
Authors: Bell Emily C. , Cox Narelle S. , Goh Nicole , Glaspole Ian , Westall Glen P. , Watson Alice , Holland Anne E.
Published: February 2017

This review aims to establish the impact of oxygen therapy on dyspnoea, health-related quality of life (HRQoL), exercise capacity and mortality in interstitial lung disease (ILD).

We included studies that compared oxygen therapy to no oxygen therapy in adults with ILD. No limitations were placed on study design or intervention type. Two reviewers independently evaluated studies for inclusion, assessed risk of bias and extracted data. The primary outcome was dyspnoea.

Eight studies evaluated the acute effects of oxygen (n=1509). There was no effect of oxygen therapy on modified Borg dyspnoea score at end exercise (mean difference (MD) −0.06 units, 95% CI −0.24–0.13; two studies, n=27). However, effects on exercise outcomes consistently favoured oxygen therapy. One study showed reduction in dyspnoea at rest with oxygen in patients who were acutely unwell (MD visual analogue scale 30 mmversus48 mm, p<0.05; n=10). Four studies of long-term oxygen therapy (n=2670) had high risk of bias and no inferences could be drawn.

This systematic review showed no effects of oxygen therapy on dyspnoea during exercise in ILD, although exercise capacity was increased. Future trials should evaluate whether acute improvements in exercise capacity with oxygen can be translated into improved physical activity and HRQoL.
Personalising airway clearance in chronic lung disease
Authors: McIlwaine Maggie , Bradley Judy , Elborn J. Stuart , Moran Fidelma
Published: February 2017

This review describes a framework for providing a personalised approach to selecting the most appropriate airway clearance technique (ACT) for each patient. It is based on a synthesis of the physiological evidence that supports the modulation of ventilation and expiratory airflow as a means of assisting airway clearance. Possession of a strong understanding of the physiological basis for ACTs will enable clinicians to decide which ACT best aligns with the individual patient's pathology in diseases with anatomical bronchiectasis and mucus hypersecretion.

The physiological underpinning of postural drainage is that by placing a patient in various positions, gravity enhances mobilisation of secretions. Newer ACTs are based on two other physiological premises: the ability to ventilate behind obstructed regions of the lung and the capacity to achieve the minimum expiratory airflow bias necessary to mobilise secretions. After reviewing each ACT to determine if it utilises both ventilation and expiratory flow, these physiological concepts are assessed against the clinical evidence to provide a mechanism for the effectiveness of each ACT. This article provides the clinical rationale necessary to determine the most appropriate ACT for each patient, thereby improving care.
What people with Down Syndrome can teach us about cardiopulmonary disease
Authors: Colvin Kelley L. , Yeager Michael E.
Published: February 2017

Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension). Cardiovascular and pulmonary diseases account for ∼75% of the mortality seen in persons with Down syndrome. This review summarises the cardiovascular, respiratory and immune challenges faced by individuals with Down syndrome, and the genetic underpinnings of their pathobiology. We strongly advocate increased comparative studies of cardiopulmonary disease in persons with and without Down syndrome, as we believe these will lead to new strategies to prevent and treat diseases affecting millions of people worldwide.
Controlling residual hydrogen gas in mass spectra during pulsed laser atom probe tomography
Authors: Kolli R. Prakash
Published: February 2017

Residual hydrogen (H2) gas in the analysis chamber of an atom probe instrument limits the ability to measure H concentration in metals and alloys. Measuring H concentration would permit quantification of important physical phenomena, such as hydrogen embrittlement, corrosion, hydrogen trapping, and grain boundary segregation. Increased insight into the behavior of residual H2 gas on the specimen tip surface in atom probe instruments could help reduce these limitations. The influence of user-selected experimental parameters on the field adsorption and desorption of residual H2 gas on nominally pure copper (Cu) was studied during ultraviolet pulsed laser atom probe tomography. The results indicate that the total residual hydrogen concentration, HTOT, in the mass spectra exhibits a generally decreasing trend with increasing laser pulse energy and increasing laser pulse frequency. Second-order interaction effects are also important. The pulse energy has the greatest influence on the quantity HTOT, which is consistently less than 0.1 at.% at a value of 80 pJ.
Energy metabolism drives myeloid-derived suppressor cell differentiation and functions in pathology
Authors: Sica Antonio , Strauss Laura
Published: February 2017

Over the last decade, a heterogeneous population of immature myeloid cells with major regulatory functions has been described in cancer and other pathologic conditions and ultimately defined as MDSCs. Most of the early work on the origins and functions of MDSCs has been in murine and human tumor bearers in which MDSCs are known to be immunosuppressive and to result in both reduced immune surveillance and antitumor cytotoxicity. More recent studies, however, suggest that expansion of these immature myeloid cells may be linked to most, if not all, chronic and acute inflammatory processes. The universal expansion to inflammatory stimuli of MDSCs suggests that these cells may be more of a normal component of the inflammatory response (emergency myelopoiesis) than simply a pathologic response to a growing tumor. Instead of an adverse immunosuppressive response, expansion of these immature myeloid cell populations may result from a complex balance between increased immune surveillance and dampened adaptive immune responses that are common to many inflammatory responses. Within this scenario, new pathways of metabolic reprogramming are emerging as drivers of MDSC differentiation and functions in cancer and inflammatory disorders, crucially linking metabolic syndrome to inflammatory processes.
The focal adhesion targeting domain of p130Cas confers a mechanosensing function

Published: February 2017

Members of the Cas family of focal adhesion proteins contain a highly conserved C-terminal focal adhesion targeting (FAT) domain. To determine the role of the FAT domain in these proteins, we compared wild-type exogenous NEDD9 with a hybrid construct in which the NEDD9 FAT domain had been exchanged for the p130Cas (also known as BCAR1) FAT domain. Fluorescence recovery after photobleaching (FRAP) revealed significantly slowed exchange of the fusion protein at focal adhesions and significantly slower two-dimensional migration. No differences were detected in cell stiffness as measured using atomic force microscopy (AFM) and in cell adhesion forces measured with a magnetic tweezer device. Thus, the slowed migration was not due to changes in cell stiffness or adhesion strength. Analysis of cell migration on surfaces of increasing rigidity revealed a striking reduction of cell motility in cells expressing the p130Cas FAT domain. The p130Cas FAT domain induced rigidity-dependent phosphorylation of tyrosine residues within NEDD9. This in turn reduced post-translational cleavage of NEDD9, which we show inhibits NEDD9-induced migration. Collectively, our data therefore suggest that the p130Cas FAT domain uniquely confers a mechanosensing function.
Advances in understanding hypopituitarism
Authors: Stieg Mareike R. , Renner Ulrich , Stalla Günter K. , Kopczak Anna
Published: February 2017

The understanding of hypopituitarism has increased over the last three years. This review provides an overview of the most important recent findings. Most of the recent research in hypopituitarism has focused on genetics. New diagnostic techniques like next-generation sequencing have led to the description of different genetic mutations causative for congenital dysfunction of the pituitary gland while new molecular mechanisms underlying pituitary ontogenesis have also been described. Furthermore, hypopituitarism may occur because of an impairment of the distinctive vascularization of the pituitary gland, especially by disruption of the long vessel connection between the hypothalamus and the pituitary. Controversial findings have been published on post-traumatic hypopituitarism. Moreover, autoimmunity has been discussed in recent years as a possible reason for hypopituitarism. With the use of new drugs such as ipilimumab, hypopituitarism as a side effect of pharmaceuticals has come into focus. Besides new findings on the pathomechanism of hypopituitarism, there are new diagnostic tools in development, such as new growth hormone stimulants that are currently being tested in clinical trials. Moreover, cortisol measurement in scalp hair is a promising tool for monitoring cortisol levels over time.
Validation of syngeneic mouse models of melanoma and non-small cell lung cancer for investigating the anticancer effects of the soy-derived peptide Lunasin
Authors: Devapatla Bharat , Shidal Chris , Yaddanapudi Kavitha , Davis Keith R.
Published: February 2017

Background: Lunasin is a naturally occurring peptide present in soybean that has both chemopreventive and therapeutic activities that can prevent cellular transformation and inhibit the growth of several human cancer types. Recent studies indicate that Lunasin has several distinct potential modes of action including suppressing integrin signaling and epigenetic effects driven by modulation of histone acetylation. In addition to direct effects on cancer cells, Lunasin also has effects on innate immunity that may contribute to its ability to inhibit tumor growth in vivo.

Methods: Standard assays for cell proliferation and colony formation were used to assess Lunasin’s in vitro activity against murine Lewis lung carcinoma (LLC) and B16-F0 melanoma cells.  Lunasin’s in vivo activity was assessed by comparing the growth of tumors initiated by subcutaneous implantation of LLC or B16-F0 cells in Lunasin-treated and untreated C57BL/6 mice.

Results: Lunasin was found to inhibit growth of murine LLC cells and murine B16-F0 melanoma cells in vitro and in wild-type C57BL/6 mice.  The effects of Lunasin in these two mouse models were very similar to those previously observed in studies of human non-small cell lung cancer and melanoma cell lines.

Conclusions: We have now validated two established syngeneic mouse models as being responsive to Lunasin treatment.  The validation of these two in vivo syngeneic models will allow detailed studies on the combined therapeutic and immune effects of Lunasin in a fully immunocompetent mouse model.

Cognitive Hierarchy in Capacity Allocation Games
Authors: Cui Tony Haitao , Zhang Yinghao
Published: February 2017

We examine a supply chain with a single supplier and multiple retailers to predict retailers’ actual ordering behaviors. If retailer orders exceed supplier capacity, a proportional rationing rule applies to capacity allocation among retailers. We propose a behavior model based on cognitive hierarchy theory, in which retailers with different levels of strategic-reasoning capabilities form heterogeneous beliefs about other players’ capabilities when choosing their orders. This behavioral model yields three interesting predictions. First, retailers’ orders increase as the number of retailers decreases or the supplier’s production capacity shrinks. Second, the orders tend to increase as the retailer population becomes more “sophisticated.” Third, retailers’ profits first increase in relation to their strategic-reasoning capabilities and then decrease, indicating an inverted U-shaped relationship between profits and strategic-reasoning capabilities. We experimentally examine the capacity allocation game with participants motivated by financial incentives. The experimental results and structural model estimation confirm the predictions of the behavioral model.

Authors: Lan Ruijun , Mateos Xavier , Wang Yicheng , Serres Josep Maria , Loiko Pavel , Li Jiang , Pan Yubai , Griebner Uwe , Petrov Valentin
Published: February 2017

We report on a Holmium micro-laser passively Q-switched by a semiconductor saturable absorber (SSA), for the first time to the best of our knowledge. It is based on a 1 at.% Ho:YAG ceramic with good energy storage capability and several commercial transmission-type SSAs with 0.24% modulation depth. Under in-band pumping by a Tm fiber laser at 1910 nm, the Ho micro-laser generated 450 mW at 2089 nm with 37% slope efficiency. Stable 89 ns, 3.2 μJ pulses are achieved at a repetition rate of 141 kHz. Further shortening of the laser pulses is feasible with the increase of the modulation depth of the SSA while power scaling may lead to Q-switching at MHz-range repetition rates.
Is the effect of a political event more pronounced for government controlled firms?
Authors: Trinugroho Irwan , Fajrin Aurio , Sutaryo Sutaryo
Published: February 2017

This study investigates market reaction to a political event, which is the presidential election of Republic of Indonesia in 2014 by studying 387 publicly traded firms in the Indonesia Stock Exchange. It employs event study method to measure the information content of this event. By going deeper, this study looked at the effect difference between government controlled firms (partially privatized firms) and private firms. The results show that there was a significant abnormal return around the event date. The negative abnormal return one day before the election date, which was followed by rebounding one day after the event, indicate that investors consider that the election had been done well particularly with respect to the political stability and security. Moreover, this paper reveals that the effect of presidential election is more pronounced for government-controlled firms than private firms. Government controlled firms may be more susceptible to political event.
The 2016 Presidential Election by the Numbers and in Historical Perspective
Authors: Jacobs Nicholas , Ceaser James W.
Published: February 2017

Using election results as our point of departure, this article places the 2016 presidential election in historical perspective. Trump’s victory was an “expected” outcome, as races following two-terms of one party rule usually go to the opposition party. Trump also ran close to fellow Republicans competing for Congress despite his unusual relationship with many of those in the party he captured. Trump’s victory in the presidential contest proved remarkably economical. He lost most of his votes relative to Romney in 2012 in places where it did not matter, while his opponent ran up the score in the states she already had locked down. We further measure the increasing geographic concentration of each major party’s electoral support and consider how this relates to the controversy over the Electoral College.

The purpose of this study was to explore the lived experiences of doctoral nursing education students who participated in a virtual mentoring program. A phenomenological design was used to enable the researchers to gain an understanding of the research phenomenon. The three patterns that emerged during the study were Confirmation of Mentoring, Building Communities, and Learning the Role of Doctoral Student. Under the pattern of Confirmation of Mentoring were the themes of Receiving Academic Support and Receiving Personal Support. Under the pattern of Building Communities were the themes of Getting to Know Mentors and Understanding the Importance of Relationships. Under the pattern of Learning of Role of Doctoral Student were the themes of Balancing Time and Learning Technology. Additional research is needed to more fully explore virtual mentoring within doctoral programs.

Published: February 2017

In this paper, we define and study the hyper S-posets over an ordered semihypergroup in detail. We introduce the hyper version of a pseudoorder in a hyper S-poset, and give some related properties. In particular, we characterize the structure of factor hyper S-posets by pseudoorders. Furthermore, we introduce the concepts of order-congruences and strong order-congruences on a hyper S-poset A, and obtain the relationship between strong order-congruences and pseudoorders on A. We also characterize the (strong) order-congruences by the ρ-chains, where ρ is a (strong) congruence on A. Moreover, we give a method of constructing order-congruences, and prove that every hyper S-subposet B of a hyper S-poset A is a congruence class of one order-congruence on A if and only if B is convex. In the sequel, we give some homomorphism theorems of hyper S-posets, which are generalizations of similar results in S-posets and ordered semigroups.

Nonlinear Dynamic Characteristics of the Railway Vehicle

Published: February 2017

The nonlinear dynamic characteristics of a railway vehicle are checked into thoroughly by applying two different wheel-rail contact model: a heuristic nonlinear friction creepage model derived by using Kalker ’s theory and Polach model including dead-zone clearance. This two models are matched with the quasi-static form of the LuGre model to obtain more realistic wheel-rail contact model. LuGre model parameters are determined using nonlinear optimization method, which it’s objective is to minimize the error between the output of the Polach and Kalker model and quasi-static LuGre model for specific operating conditions. The symmetric/asymmetric bifurcation attitude and stable/unstable motion of the railway vehicle in the presence of nonlinearities which are yaw damping forces in the longitudinal suspension system are analyzed in great detail by changing the vehicle speed. Phase portraits of the lateral displacement of the leading wheelset of the railway vehicle are drawn below and on the critical speeds, where sub-critical Hopf bifurcation take place, for two wheel-rail contact model. Asymmetric periodic motions have been observed during the simulation in the lateral displacement of the wheelset under different vehicle speed range. The coexistence of multiple steady states cause bounces in the amplitude of vibrations, resulting instability problems of the railway vehicle. By using Lyapunov’s indirect method, the critical hunting speeds are calculated with respect to the radius of the curved track parameter changes. Hunting, which is defined as the oscillation of the lateral displacement of wheelset with a large domain, is described by a limit cycle-type oscillation nature. The evaluated accuracy of the LuGre model adopted from Kalker’s model results for prediction of critical speed is higher than the results of the LuGre model adopted from Polach’s model. From the results of the analysis, the critical hunting speed must be resolved by investigating the track tests under various kind of excitations.
Cut and Tape: Marguerite Yourcenar’s Emendations to a Typescript of L’Œuvre au noir
Authors: Smith Theresa J. , Burns Thea
Published: February 2017

Marguerite Yourcenar’s manuscript L’Œuvre au noir was off limits to scholars for years because of its fragile condition. In all there were 6,725 inches (17,081.5 cm) of rubber-based and synthetic adhesive tapes used in the two-volume manuscript. The primary challenge was the failure of the rubber-based adhesive, causing the composite leaves to flutter in a pile of paper scraps when a page was turned. To complicate matters, Yourcenar often typed and wrote directly on the tapes, necessitating their preservation and reattachment. It took two conservators 290 hours to stabilize this manuscript, facilitating safe consultation by researchers.

Paz-Franco, A, Rey, E, and Barcala-Furelos, R. Effects of three different resistance training frequencies on jump, sprint, and repeated sprint ability performances in professional futsal players. J Strength Cond Res 31(12): 3343–3350, 2017—The aim of this study was to examine the effect of 3 different resistance training (RT) frequencies (1 strength training session per week [1W], 2 strength training sessions per week [2W], or 1 strength training session every second week [0.5W]) on jump, sprint, and repeated sprint ability (RSA) performances in professional futsal players. Thirty-five futsal players were randomized into 1 of 3 groups, the 1W group (n = 12), 2W group (n = 12), or the 0.5W group (n = 11). The players performed the same RT during 6 weeks, and only training frequency differed between the groups. Within-group analysis showed significant improvements in jump (p ≤ 0.001, effect size [ES] = 0.13–0.35), sprint (p ≤ 0.001, ES = 0.48–0.71), and RSA (p ≤ 0.01, ES = 0.22–0.63) from pretest to posttest in 1W and 2W groups. However, no significant (p > 0.05) pre-post changes were observed for the 0.5W group in any variable. In the between-groups analysis, significant better results were found in jump (p ≤ 0.01), sprint (p ≤ 0.01), and RSA performances (p ≤ 0.01) in the 1W and 2W groups in comparison with 0.5W group. Also, jump (p ≤ 0.05) and 5-m sprint (p ≤ 0.05) performances were significantly better in the 2W group in comparison with 1W group. In conclusion, the current study showed that 6 weeks of RT 1 or 2 times per week in addition to typical futsal training produced significant improvements in jump, sprint, and RSA performances. Additionally, RT once every second week may be sufficient to maintain physical fitness in professional futsal players. This information may be useful for coaches when planning training contents during congested fixture schedules or in periods where the emphasis needs to be put on other qualities and to spend as little time as possible on maintaining or increasing physical performance.

Bullock, GS, Schmitt, AC, Chasse, PM, Little, BA, Diehl, LH, and Butler, RJ. The relationship between trunk rotation, upper quarter dynamic stability, and pitch velocity. J Strength Cond Res 32(1): 261–266, 2018—Understanding the relationship between upper quarter mobility, dynamic stability, and pitching velocity may be beneficial in elucidating underlying factors that affect pitching performance. The purpose of this study was to investigate upper trunk rotation mobility and upper quarter dynamic stability and their correlation to pitch velocity in NCAA Division I collegiate pitchers. We hypothesized that collegiate pitchers with greater upper trunk rotation mobility and upper extremity dynamic stability would exhibit higher pitching velocity. Trunk rotation and the Upper Quarter Y-Balance Test (YBT-UQ) were measured using standardized protocols. Collegiate pitchers (N = 30) then proceeded to complete their team prescribed dynamic and throwing warm-up followed by a pitching session from regulation distance at 100% effort. Each pitch was recorded for velocity and pitch type, only fastballs were used in analysis. The relationships between trunk rotation and fastball velocity, and YBT-UQ scores and fastball velocity were assessed using a series of 2-tail Pearson's correlations (p < 0.05). Throwing and nonthrowing sides (69.6 ± 9.5°, 70.7 ± 9.4°) had similar trunk rotation mobility. No statistically significant correlation between upper trunk rotation mobility and pitch velocity was found (throwing arm: r = 0.131; p < 0.491; nonthrowing arm: r = 0.135; p < 0.478). There was also no correlation between the YBT-UQ and fastball velocity. In this study of Division I baseball pitchers, we found no relationship between trunk rotational mobility, upper quarter dynamic stability, and pitching velocity. This suggests that increased upper extremity stability and trunk mobility are not directly related to fastball velocity. Understanding factors that associate to velocity may be helpful in predicting pitching performance.
