Risk of Suicide Attempt Among Soldiers in Army Units With a History of Suicide Attempts

Importance Mental health of soldiers is adversely affected by the death and injury of other unit members, but whether risk of suicide attempt is influenced by previous suicide attempts in a soldier’s unit is unknown. Objective To examine whether a soldier’s risk of suicide attempt is influenced by previous suicide attempts in that soldier’s unit. Design, Setting, and Participants Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (STARRS), this study identified person-month records for all active-duty, regular US Army, enlisted soldiers who attempted suicide from January 1, 2004, through December 31, 2009 (n = 9650), and an equal-probability sample of control person-months (n = 153 528). Data analysis was performed from August 8, 2016, to April 10, 2017. Main Outcomes and Measures Logistic regression analyses examined the number of past-year suicide attempts in a soldier’s unit as a predictor of subsequent suicide attempt, controlling for sociodemographic features, service-related characteristics, prior mental health diagnosis, and other unit variables, including suicide-, combat-, and unintentional injury–related unit deaths. The study also examined whether the influence of previous unit suicide attempts varied by military occupational specialty (MOS) and unit size. Results Of the final analytic sample of 9512 enlisted soldiers who attempted suicide and 151 526 control person-months, most were male (86.4%), 29 years or younger (68.4%), younger than 21 years when entering the army (62.2%), white (59.8%), high school educated (76.6%), and currently married (54.8%). In adjusted models, soldiers were more likely to attempt suicide if 1 or more suicide attempts occurred in their unit during the past year (odds ratios [ORs], 1.4-2.3; P P P Conclusions and Relevance Risk of suicide attempt among soldiers increased as the number of past-year suicide attempts within their unit increased for combat arms and other MOSs and for units of any size but particularly for smaller units. Units with a history of suicide attempts may be important targets for preventive interventions.
Knitting Activism, Knitting Gender, Knitting Race

Graffiti knitting, the practice of knitting objects and installing them without permission in public, is part of a larger craftivist turn in contemporary activism. It builds on a feminist history of activist knitting and resonates today because of its synthesis of the material and the affective, and through these means crafting a more participatory politics. This approach has facilitated, however, blindness to the racial politics of a largely White feminist appropriation of graffiti. This works against craftivism’s political potential and mirrors larger concerns about participatory politics. As a scholar-activist, I critique graffiti knitting to point toward ways for it to evolve and become a more intersectional activist practice.
Alternative estimation methods for identifying contagion effects in dynamic social networks: A latent-space adjusted approach

Abstract Contagion effects, also known as peer effects or social influence process, have become more and more central to social science, especially with the availability of longitudinal social network data. However, contagion effects are usually difficult to identify, as they are often entangled with other factors, such as homophily in the selection process, the individual’s preference for the same social settings, etc. Methods currently available either do not solve these problems or require strong assumptions. Following Shalizi and Thomas (2011), I frame this difficulty as an omitted variable bias problem, and I propose several alternative estimation methods that have potentials to correctly identify contagion effects when there is an unobserved trait that co-determines the influence and the selection. The Monte-Carlo simulation results suggest that a latent-space adjusted estimator is especially promising. It outperforms other estimators that are traditionally used to deal with the unobserved variables, including a structural equation based estimator and an instrumental variable estimator.
Microdissection of Primary Renal Tissue Segments and Incorporation with Novel Scaffold-free Construct Technology

Kidney transplantation is now a mainstream therapy for end-stage renal disease. However, with approximately 96,000 people on the waiting list and only one-fourth of these patients achieving transplantation, there is a dire need for alternatives for those with failing organs. In order to decrease the harmful consequences of dialysis along with the overall healthcare costs it incurs, active investigation is ongoing in search of alternative solutions to organ transplantation. Implantable tissue-engineered renal cellular constructs are one such feasible approach to replacing lost renal functionality. Here, described for the first time, is the microdissection of murine kidneys for isolation of living corticomedullary renal segments. These segments are capable of rapid incorporation within scaffold-free endothelial-fibroblast constructs which may enable rapid connection with host vasculature once implanted. Adult mouse kidneys were procured from living donors, followed by stereoscope microdissection to obtain renal segments 200 - 300 µm in diameter. Multiple renal constructs were fabricated using primary renal segments harvested from only one kidney. This method demonstrates a procedure which could salvage functional renal tissue from organs that would otherwise be discarded.
Sources of Variation that Affect Perceived Nursery Function of Mangroves

Mangroves are considered among the most productive ecosystems on the planet. While mangroves provide numerous critical ecosystem services to surrounding environments, there is particular interest in the role of mangroves as nursery habitats for fish and decapods. Despite this interest, scientific consensus regarding the role of mangroves as nurseries remains elusive. In this chapter, we identify four principal sources of variability that underlie conflicting conclusions regarding the function of mangroves as nursery habitat. We provide brief sketches of the reasons why these sources of variability may affect the role of mangroves as nursery habitat, drawing particularly on recent empirical advances in the field, and conclude with a conceptual model summarizing the different levels at which the nursery function of mangroves is evaluated.
Human nature and morality: a sociobiological perspective.

“The philosophic attitude is a resolute attempt to enlarge the understanding of the scope of application of every notion which enters into our current thought” (Whitehead, 1938:233-34). There is probably no parallel in the history of thought either to Aristotle's breadth of scholarly attainment or to the historical reach of his intellectual influence. Sociobiologists, therefore, can only be enthusiastic about any attempt, such as Arnhart's, to bring such resources to bear on their still young endeavors.
A new approach to speech enhancement by a microphone array using EM and mixture models.

Speech enhancement and recognition in noisy, reverberant conditions is a challenging open problem. We present a new approach to this problem, which is developed in the framework of probabilistic modeling. Our approach incorporates information about the statistical structure of speech signals using a speech model, which is pre-trained on a large dataset of clean speech. The speech model is a component in a larger model describing the observed sensor signals. That model is parametrized by the coefficients of the reverberation filters and the spectra of the sensor noise. We develop an EM algorithm that estimates those parameters from data and constructs a Bayes optimal estimator of the original speech signal.
ECT in an Adolescent with Down Syndrome and Treatment-Refractory Major Depressive Disorder

The efficacy of electroconvulsive therapy (ECT) as a treatment for patients with major depressive disorder who are intolerant of or refractory to antidepressant medications is well known. This treatment may be overlooked in children and adolescents, and in those with developmental disabilities. The case report of a 15-year-old male with Down syndrome and treatment-refractory major depressive disorder who received ECT is presented. Four bilateral ECT treatments resulted in a substantial improvement of the patient's depressive symptoms. In this case, ECT was a safe and effective treatment for an adolescent with Down syndrome. Although no generalization can be based on a single case report, when appropriate, ECT should be considered as a treatment for this patient population.

In this note, an example is constructed which illustrates one of the major results of the contribution of N. Hopkins [1] to these proceedings.
Aircraft Structural Layout

An introduction to the structural layout of conventional GA aircraft is provided. Special mentioning of aircraft loads is made to help the student understand how different parts of the aircraft structure are designed to react a specific type of load. Then, information on the characteristics and properties of typical materials used for the construction of the modern GA aircraft. This includes aluminum, steel, titanium, and composite materials. The last section of the chapter presents a description of the fabrication of and installation of various structural components for aircraft, such as the fuselage, wing, and stabilizing surfaces.
Molecular Diversity of Intrinsically Photosensitive Ganglion Cells

Intrinsically photosensitive retinal ganglion cells (ipRGCs) are rare mammalian photoreceptors essential for non-image-forming vision functions, such as circadian photoentrainment and the pupillary light reflex. They comprise multiple subtypes distinguishable by morphology, physiology, projections, and levels of expression of melanopsin (Opn4), their photopigment. The molecular programs that differentiate ipRGCs from other ganglion cells and ipRGC subtypes from one another remain elusive. Here, we present comprehensive gene expression profiles of early postnatal and adult mouse ipRGCs purified from two lines of reporter mice marking different sets of ipRGC subtypes. We find dozens of novel genes highly enriched in ipRGCs. We reveal that Rasgrp1 and Tbx20 are selectively expressed in subsets of ipRGCs, though these molecularly defined groups imperfectly match established ipRGC subtypes. We demonstrate that the ipRGCs regulating circadian photoentrainment are unexpectedly diverse at the molecular level. Our findings reveal unexpected complexity in gene expression patterns across mammalian ipRGC subtypes.
Diagnostic and Power Feed Upgrades to the MAIZE Facility

The Michigan Accelerator for Inductive Z-pinch Experiments (MAIZE) is a single-stage, 1-MA linear transformer driver at the University of Michigan. The MAIZE facility has been the site of various experimental studies, including wire array Z-pinches for X-ray source development and cylindrical foil loads for implosion stability analysis. In order to better understand and investigate these and other experiments, a 4-frame extreme ultraviolet camera was implemented, the optical stability of a 12-frame laser shadowgraphy system was improved, B-dot probes were upgraded, and a Rogowski coil was constructed. New conical load hardware was also developed to reduce the inductance of the transmission line and thus improve the current delivered to the loads.
Path Following Control of Swimming Magnetic Helical Microrobots Subject to Step-Out Frequencies

This paper investigates the problem of straight-line path following for planar swimming magnetic helical microrobots. The control objective is to make the microrobot to converge to a straight line without violating the input saturation limits. The proposed feedback control solution is based on an optimal decision strategy (ODS) that is cast as a quadratic program. The ODS-based control law minimizes the difference between the microrobot velocity and a line-of-sight (LOS)-based reference vector field while respecting the input saturation constraints.
PROFILE OF OLDER WORKERS USING THE NATIONAL HEALTH & AGING TRENDS STUDY

The US is experiencing a substantial increase in the proportion of the population who is 65 and older. This “greying of America” necessitates a reexamination of employment and health policies to ensure the economic viability and health of the US population. Older workers are a growing segment of the US workforce representing both a highly experienced and valuable group of individuals; however, due to a myriad of factors, older workers are especially vulnerable to involuntary job loss as they age. Cross sectional analysis using data from the 2016 wave of the National Health & Aging Trends Study was used to provide weighted estimates examining a broad range of health, behavioral, and sociodemographic factors related to older worker labor force participation. Overall, 21% of community dwelling older adults (N=5930) reported working for pay in the last month, with 6% reporting health/function preventing their participation in work. Among current workers (n=946), administrative (11.8%), sales (9.8%), and managerial (8.2%) positions were the most common occupations older adults held. Gender, race, and age all play a significant role in the likelihood of older adult participation in the workforce. By understanding the current profile of older workers in the US, we can more effectively target health and policy resources to support productive and successful aging among older adults seeking to participate in the US workforce.
Screening and Referral for Low-Income Families’ Social Determinants of Health by US Pediatricians

Abstract Objective To measure the frequency US pediatricians report screening and referring for social needs and identify pediatrician and practice-level predictors for screening and referral. Methods Data were from the American Academy of Pediatrics Periodic Survey for October 2014 to March 2015 with a response rate of 46.6% (732/1570). Respondents reported on: 1) routine screening of low-income families for social needs, 2) attitudes toward screening, and 3) referral of low-income families for community resources. Results were analyzed by pediatrician and practice characteristics. Results Although most pediatricians (61.6%) thought that screening is important, fewer (39.9%) reported that screening is feasible or felt prepared addressing families' social needs (20.2%). The topics that pediatricians reported routinely asking low-income families about at visits (defined as ≥50% visits) were need for childcare (41.5%) and transportation barriers (28.4%). Pediatricians were less likely to report asking about housing (18.7%), food (18.6%), and utilities/heating (14.0%) insecurity. In multivariable analyses, pediatricians were more likely to report both that they screen and refer when they reported having more patients in financial hardship and having someone in the practice with the responsibility to connect low-income families to community services. Pediatricians who endorsed the importance of screening and who reported being prepared were also more likely to screen/refer. Conclusions A minority of pediatricians report routinely screening for social needs. Pediatricians were more likely to report that they screen and refer if they had positive attitudes toward the importance of screening, felt prepared, and had support staff to assist families in need.
Did the Romans Have a Future

In analysing matters as diverse as state financing, strategic planning, public benefactions and long-term credit in private business transactions, the historian is faced with an underlying problem about the perceptions of time. One aspect of this problem is the manner in which pictures of a complex future are reflected in the behaviour of agents engaged in these activities. The manner in which actions were (or were not) taken by them suggests a peculiar configuration of future time in the Roman world. It is speculatively argued that perspectives on the future had analogies with the different ways in which a sense of depth was created by artists working on a two-dimensional space and with the contextual ways in which spatial perspective was employed.
Meaning and Management of Multiple Medications Among Public Mental Health Service Users

Public mental health service users frequently manage multiple health conditions, and are often prescribed multiple medications. While medications are useful tools in treating diagnosed mental illnesses, they bring management challenges and also can carry complex meanings for the individuals taking them. This study utilized a qualitative methodological approach to examine the experience and meaning of polypharmacy among public mental health services users. This sample of service users (n = 26) who were prescribed multiple medications described three distinct types of challenges they faced in managing medications: related to information, material tasks, and self-stigma. Nevertheless, respondents reported creative and resilient strategies to manage these challenges. Findings build on previous literature and reflect the increasing need to focus on challenges related to polypharmacy. Furthermore, findings indicate that low levels of literacy and high levels of material disadvantage, which are common among public mental health service users, complicate the management and meaning of multiple medications.
Preserving and Achieving Passivity-Short Property Through Discretization

Although passivity has been proven to be quite useful, it excludes a majority of dynamic systems in applications, and typically, the property cannot be preserved through discretization. To overcome these shortcomings, the class of passivity-short (PS) systems is investigated in this article, and canonical forms are derived in both continuous-time and discrete-time domains. Explicit conditions are found to guarantee the PS property through discretizing PS/non-PS systems and, for those that do not satisfy the conditions, two designs of output feedback controls are presented to make sampled-data systems PS, regardless of the PS property of original continuous-time systems. One of the designs is in the discrete-time domain, and the other is in the continuous-time domain. The control design to ensure the PS property in the continuous-time domain is also developed. These results provide a full description of PS systems in both domains as well as their relationship through discretization.
Adaptation to inflammatory acidity through neutrophil-derived adenosine regulation of SLC26A3

Acute intestinal inflammation includes the early accumulation of neutrophils (PMN). Based on recent evidence that PMN infiltration "imprints" changes in the local tissue environment through local oxygen depletion and the release of adenine nucleotides, we hypothesized that the interaction between transmigrating PMN and intestinal epithelial cells (IECs) results in inflammatory acidification of the tissue. Using newly developed tools, we revealed that active PMN transepithelial migration (TEM) significantly acidifies the local microenvironment, a decrease of nearly 2 pH units. Using unbiased approaches, we sought to define acid-adaptive pathways elicited by PMN TEM. Given the significant amount of adenosine (Ado) generated during PMN TEM, we profiled the influence of Ado on IECs gene expression by microarray and identified the induction of SLC26A3, the major apical Cl-/HCO3- exchanger in IECs. Utilizing loss- and gain-of-function approaches, as well as murine and human colonoids, we demonstrate that Ado-induced SLC26A3 promotes an adaptive IECs phenotype that buffers local pH during active inflammation. Extending these studies, chronic murine colitis models were used to demonstrate that SLC26A3 expression rebounds during chronic DSS-induced inflammation. In conclusion, Ado signaling during PMN TEM induces an adaptive tissue response to inflammatory acidification through the induction of SLC26A3 expression, thereby promoting pH homeostasis.
Multidimensional aspects of dyspnea in obese patients referred for cardiopulmonary exercise testing.

Abstract We investigated the contributions of obesity on multidimensional aspects of dyspnea on exertion (DOE) in patients referred for clinical cardiopulmonary exercise testing (CPET). Ratings of perceived breathlessness (RPB, Borg scale 0–10) were collected in obese (BMI ≥ 30; n = 47) and nonobese (BMI ≤ 25; n = 27) patients during two (one lower: ∼30 W; and one higher: ∼50 W) 4−6 min constant load cycling bouts. Multidimensional dyspnea profiles (MDP) were collected in the final 26 obese and 14 nonobese patients of the sample. RPB was greater (p = 0.05) in obese (3.3 ± 2.2 vs 2.4 ± 1.4) at lower work rates, but similar at higher work rates (4.9 ± 2.2 vs 4.4 ± 1.8). MDP sensory score including unpleasantness was 4.3 ± 2.2 in obese vs 2.5 ± 1.9 in nonobese (p
Sugarcane bagasse and rice husk ash pozzolans: Cement strength and corrosion effects when using saltwater

Abstract The production of ordinary Portland cement (OPC) contributes to the release of harmful greenhouse gases. In an effort to reduce these emissions, this study explores biomass materials to evaluate their use as partial replacements for ordinary Portland cement. Rice husk and sugarcane bagasse are agricultural waste products and large amounts of these are currently landfilled, making them inexpensive and available. When combusted at high temperatures they form rice husk ash and sugarcane bagasse ash with pozzolanic characteristics. The high silicon dioxide levels in these products make them good options to use as partial replacement for OPC. Replacement with 20% rice husk ash or 10% sugarcane bagasse ash give similar compressive strength and corrosion resistance for hardened cement paste samples compared to control OPC samples, if appropriate amounts of plasticizer are used. Porosity as measured by water adsorption trended higher with increased water to cement ratio due to replacement of cement with pozzolan, since water to binder ratio remained constant at 0.45:1. This study used saltwater in the mix, to investigate the use of a resource that requires less energy use in ocean-bordering areas.
Analysis of the measurement properties of the Brazilian-Portuguese version of the Tampa Scale for Kinesiophobia-11 in patients with fibromyalgia.

Abstract Objective To analyze the measurement properties of the Brazilian-Portuguese version of the Tampa Scale for Kinesiophobia-11 in patients with fibromyalgia. Methods Assessment was made at three time points: baseline (n = 130) and 15 days (n = 54) and eight weeks after baseline (n = 51). Data collected at baseline were used to assess internal consistency, criterion and construct validity, and ceiling and floor effects. Data collected at baseline and 15 days after baseline were used to assess reliability and measurement error, and data collected before and after an eight-week exercise-based physical therapy intervention were used to assess interpretability of change scores. Results The Tampa Scale for Kinesiophobia-11 showed adequate internal consistency (Cronbach's alpha = 0.77; alpha if item deleted: 0.74–0.77), substantial reliability (intraclass correlation coefficient2,1 = 0.85; 95% confidence interval: 0.75, 0.90), good measurement error (standard error of measurement: 2.65 points), and a minimal detectable change (90% confidence) of 6.16 points. For validity, the Tampa Scale for Kinesiophobia-11 showed a positive and good correlation with the original Tampa Scale for Kinesiophobia (r = 0.84, p Conclusion The Tampa Scale for Kinesiophobia-11 is consistent, reliable, and appropriate to assess fear of movement in patients with fibromyalgia in the clinical context. Responsiveness of the Tampa Scale for Kinesiophobia-11 should be tested in future studies.
The Access to Literacy Assessment System for Phonological Awareness: An Adaptive Measure of Phonological Awareness Appropriate for Children with Speech and/or Language Impairment.

Purpose The Access to Literacy Assessment System-Phonological Awareness (ATLAS-PA) was developed for use with children with speech and/or language impairment. The subtests (Rhyming, Blending, and Segmenting) are appropriate for children who are 3-7 years of age. ATLAS-PA is composed entirely of receptive items, incorporates individualized levels of instruction, and is adaptive in nature. Method To establish the construct validity of ATLAS-PA, we collected data from children with typical development (n = 938) and those who have speech and/or language impairment (n = 227). Results Rasch analyses indicated that items fit well together and formed a unidimensional construct of phonological awareness. Differential item functioning was minimal between the two groups of children, and scores on ATLAS-PA were moderately to strongly related to other measures of phonological awareness. Information about item functioning was used to create an adaptive version of ATLAS-PA. Conclusions Findings suggest that ATLAS-PA is a valid measure of phonological awareness that can be used with children with typical development and with speech and/or language impairment. Its adaptive format minimizes testing time and provides opportunities for monitoring progress in preschool and early elementary classrooms.

Unified Approach for the Design, Manufacture and Test of an Off-Road Rubber Tracked Ground Vehicle (TGV)

The work in this paper proposes a unified approach which involves the design, manufacture, and test an off-road rubber tracked ground vehicle for rugged terrain conditions. The proposed vehicle overall design consists of rubber tracking system, main chassis, power train and transmission system,, steering system, suspension system and the vehicle body. The design approach of the rubber tracking system can be considered new, simple, easy to manufacture and cheap compared with what is available in the literature. The dimensions of the designed rubber tracking system are of contact length of 1700 mm, track height of 850 mm, and track width of 380 mm. The overall proposed design weight of the vehicle is 14.714 kN of 3500 mm length, 2000 mm wide, 1550 mm height with minimum ground clearance of 200 mm. A 165hp Subaru gasoline engine with transmission system, suspension system, braking system, exhaust and fuel system were selected, other parts of the vehicle were designed and manufactured such as the main chassis, rubber tracking system, steering system. Finally, the vehicle was tested and after several run trials, it was performing successfully.
Expression of a foreign antigen by intratumoral DNA electroporation to enhance anti-tumor immune response

1885 Most tumor-associated antigens (TAA) are normal self-proteins that induce weak immune responses because of immunological tolerance. A major challenge in cancer immunotherapy is how to enhance such immune responses. We hypothesize that a strong immune reactivity to a foreign recall antigen expressed intratumorally will cause tumor cell destruction and lead to enhanced immune priming to TAA. To test the feasibility of expressing a foreign antigen in a solid tumor, we monitored the activity of firefly luciferase introduced into BALB/c mammary tumors D2F2 by DNA electroporation. Mice were inoculated subcutaneously with 1x105 D2F2 cells. When tumors reached 3x3 mm in size, mice received 100-200 μg of luciferase DNA in 50-100 μl of PBS intratumorally (i.t.) twice, 3 days apart. Each DNA injection was followed immediately by electroporation at the injection site using a tweezer electrode to deliver 8 pulses, each at 100 V for 25 msec. Luciferase activity was measured twice a wk starting on d.7 after the 1st DNA electroporation. Mice received i.v. injection of 1.6 mg D-luciferin, the luciferase substrate, and were imaged with the Kodak IS4000MM small animal imager. The intratumoral luciferase activity was maximal between d.7 and d.10 after the 1st DNA electroporation and declined progressively until no activity was detected on d.21. Intratumoral expression of luciferase was verified by in vitro luciferase assay of the tumor lysate. To test whether i.t. DNA electroporation induced immune reactivity to the expressed foreign protein, pE2TM DNA was electroporated into D2F2 tumor. pE2TM encodes the extracellular and transmembrane domains of human ErbB-2 (Her-2), a TAA overexpressed in several types of human cancers. Her-2 is the human homolog of mouse ErbB-2 and a foreign, heterologous Ag in mice. After two i.t. DNA electroporations, Her-2-specific antibodies and T cells were detected by flow cytometry and IFN-γ ELISPOT, respectively. These results demonstrate the feasibility of expressing a foreign antigen by i.t. DNA electroporation and its recognition by the immune system, suggesting the possibility of converting a solid tumor into a cancer vaccine reservoir. The effect of intratumoral delivery of a foreign recall antigen on tumor cell destruction and immune priming to TAA is under investigation. This work is supported by CA76340, CA125680, and Wayne State University.
Anterior hip dislocation complicated by thrombus in the common femoral vein: A case report

Abstract Case A 90-year-old male sustained a low energy anterior hip dislocation without fracture after a ground-level fall. Magnetic resonance imaging (MRI) detected femoral vessel compression and thrombosis. The patient underwent placement of an inferior vena cava (IVC) filter prior to successful closed reduction in the operating room. Conclusion Anterior hip dislocations are rare events that require urgent intervention to reduce the risk of complications. One underreported complication is femoral vessel thrombosis from direct compression against the femoral head. Dedicated imaging should be considered to rule out a thrombus. An IVC filter can be placed prior to reduction attempts to avoid potential thrombotic emboli.
Predictors of Patient Satisfaction in Spine Surgery: A Systematic Review.

Background Recently, there has been increased interest in patient satisfaction measures such as Press Ganey and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. In this systematic review, the spine surgery literature is analyzed to evaluate factors predictive of patient satisfaction as measured by these surveys. Methods A thorough literature search was performed in PubMed/MEDLINE, Google Scholar, and Cochrane databases. All English-language articles from database inception to July 2020 were screened for study inclusion according to PRISMA guidelines. Results Twenty-four of the 1899 published studies were included for qualitative analysis. There has been a statistically significant increase in the number of publications across years (P = 0.04). Overall, the studies evaluated the relationship between patient satisfaction and patient demographics (71%), preoperative and intraoperative clinical factors (21%), and postoperative factors (33%). Top positive predictors of patient satisfaction were patient and nursing/medical staff relationship (n = 4; 17%), physician–patient relationship (n = 4; 17%), managerial oversight of received care (n = 3; 13%), same sex/ethnicity between patient and physician (n = 2; 8%), and older age (n = 2; 8%). Top negative predictors of patient satisfaction were high Charlson Comorbidity Index/high disability/worse overall health functioning (n = 7; 29%), increased length of hospital stay (n = 4; 17%), high rating for pain/complications/readmissions (n = 4; 17%), and psychosocial factors (n = 3; 13%). Conclusions There is heterogeneity in terms of different factors, both clinical and nonclinically related, that affect patient satisfaction ratings. More research is warranted to investigate the role of hospital consumer surveys in the spine surgical patient population.
Larger, Counter-intuitive and Lasting – The PSM role in responding to the COVID-19 pandemic, exploring opportunities for theoretical and actionable advances

Abstract PSM has played an important role in the initial mitigation of risks caused by the COVID-19 pandemic. We explore the nature and scope of this role and develop a roadmap for PSM contributions towards greater supply chain resilience. We find that the role of PSM is (1) multidimensional; responding to supply risks but also to demand and logistics risks, (2) counter to game theory; collaboration increased instead of decrease, (3) multi-stage; beyond the initial response the hardest change efforts are still ahead. The pandemic is accelerating the journey towards future-proof PSM but not necessarily revolutionizing the future of PSM.
Senomorphic, senolytic, and rejuvenation therapies

Abstract Chronic kidney disease is an increasing burden for public health, especially in older population. Impaired regenerative capacity of endogenous renal stem or progenitor cells is partly responsible for renal tissue fibrosis. Accumulating evidences suggest that stress-induced cellular senescence is involved in acute or chronic kidney injury and may affect reparative cells and impair renal regenerative capacity. Several classes of drugs have been introduced to blunt cellular senescence. Senomorphics that target senescence-associated secretory phenotype and senolytics, which clear senescent cells, have been shown to attenuate kidney injury. This chapter introduces the strategies and advances in senomorphics and senolytic treatments in kidney diseases and rejuvenation therapy.
Prevalence and Predictors of Cyber Psychological Abuse among Adults

Communication technologies, including cell phones, social media, and location tracking services, can be used to perpetrate abuse against current or former intimate partners. A growing literature examines these behaviors in adolescent and college samples, yet very little research has investigated cyber abuse prevalence and risk factors in broader samples of adults. The present study examines whether in-person forms of intimate partner aggression (IPA) and important IPA risk factors are associated with cyber psychological abuse (CPA) in a sample of adults (N = 243; Mean age = 33.49, SD = 11.31) who reported being in a romantic relationship within the last 12 months and were recruited through Amazon’s Mechanical Turk. Participants completed assessments of CPA, physical assault, emotional abuse, maltreatment history, attachment insecurity, jealousy, emotion dysregulation, substance abuse, and relationship functioning. The Cyber Psychological Abuse scales significantly and positively correlated with physical assault and emotional abuse. Multivariate risk factor analyses accounted for 40% and 30% of the variance in CPA perpetration and victimization, respectively. Behavioral jealousy, relationship discord, and extent of daily cell phone use had significant unique associations with both CPA perpetration and victimization. The results indicate that CPA is highly prevalent among adults, strongly associated with other forms of IPA, and correlated with both IPA risk factors and extent of technology use. Findings support the further development of efforts to prevent CPA, to educate potential CPA victims, and to assess and address CPA among adults who engage in or experience in-person forms of partner abuse.
Second errata to “Distance covariance in metric spaces”

There is a slight gap and error in Remark 3.4 of Ann. Probab. 41, no. 5 (2013), 3284–3305, that was not noticed before the first errata were published (Ann. Probab. 46, no. 4 (2018), 2400–2405). We take this opportunity to provide some additional updates as well.
Body weight change and mortality in a cohort of elderly patients recently discharged from the hospital.

OBJECTIVES: To evaluate the prognostic significance of weight change in frail elderly patients. DESIGN: Prospective study. SETTING: The general medical or surgical wards of a university-affiliated Department of Veterans Affairs hospital. PARTICIPANTS: Six hundred sixty randomly selected subjects aged 65 or older. MEASUREMENTS: At admission and discharge, each subject completed a standardized diagnostic evaluation, including demographic variables, and basic medical, functional, and nutritional assessments. Weights were recorded from hospital or clinic visits in the year before admission, during the current hospitalization, and after discharge for a median of 5.6 years. Average yearly intraindividual weight change was calculated using least-squares regression. Associations between intraindividual weight change and mortality were identified using Cox proportional hazards regression. RESULTS: During the study, 314 subjects (48%) died. A Ushaped association between weight change and mortality was observed. Those who were relatively weight stable ( � 1 kg/y) had the lowest mortality (28%). Compared with this group, the adjusted relative risks (ARR) of death for those who lost 1 or more to less than 3 kg/y and 3 or more kg/y were 2.14 (95% confidence interval (CI) 51.52‐3.00) and 3.59 (95% CI 52.58‐4.99), respectively. The ARR associated with a weight gain of 1 or more to less than 3 kg/y and 3 or more kg/y was 1.38 (95% CI 50.91‐2.10) and 3.73 (95% CI 52.34‐5.94), respectively. The amount of bidirectional weight fluctuation (estimated using coefficient of variance) was not significantly associated with mortality.

Simple solutions of the free-edge stresses in composite laminates under thermal and mechanical loads

Intense and localized interlaminar stresses generally occur in a narrow boundary region near the free edge of a multilayered anisotropic laminate under mechanical and temperature loads. Quantitative measures of interlaminar action across interfaces may be readily obtained through purely algebraic operations, even if nonlinear and inelastic material behavior becomes significant in the boundary region due to severe strain concentration. These measures are the limiting values of the Lekhnitskii stress functions F and Psi (and of the normal derivative of F) along interfaces and toward the interior region of the laminate. In the present work, they are used as the basis of an exceedingly simple and efficient method of interlaminar stress analysis that is potentially applicable to free-edge problems involving nonlinear thermoelastic constitutive relations. Example solutions are obtained for symmetric, four-layer, cross-ply, and angle-ply laminates under a temperature load and two different types of strain loads, and the results are found to be in reasonable agreement with the existing numerical and analytical solutions based on elaborate analysis methods. 13 refs.
Transport Properties of QCD at Large N(c) and the Gauge / String Duality

Below the deconfinement phase transition large $N_c$ QCD is expected to be a very viscous hadronic fluid because both the shear and bulk viscosity to entropy density ratio, $\eta/s,\zeta/s \sim N_c^2$. In this letter I show that $\eta/s \sim N_c^2$ in the confined phase of holographic models of QCD at large $N_c$ defined in the supergravity approximation. Our results show that the gauge/string duality can be used to describe not only nearly perfect fluids but also extremely viscous systems such as a cold gas of glueballs.
LSIL: Definition and Management

The management of low-grade squamous intraepithelial lesions (LSIL) has changed greatly over the past 2 decades. The most recent recommendations propose avoiding treatment while continuing to monitor patients for clearance of disease or a change to a more severe diagnosis. Knowledge of the correct way to manage LSIL is important because LSIL is a relatively common diagnosis found on cervical cytology. Especially since the introduction of liquid-based cytology, the diagnosis of LSIL has become more frequent. The College of American Pathologists estimated in 2003 that the reporting rate for LSIL was 2.9%.
Super-Resolved Surface Reconstruction from Multiple Images

This paper describes a Bayesian method for constructing a super-resolved surface model by combining information from a set of images of the given surface. We develop the theory and algorithms in detail for the 2-D reconstruction problem, appropriate for the case where all images are taken from roughly the same direction and under similar lighting conditions. We show the results of this 2-D reconstruction on Viking Martian data. These results show dramatic improvements in both spatial and gray-scale resolution. The Bayesian approach uses a neighbor correlation model as well as pixel data from the image set. Some extensions of this method are discussed, including 3-D surface reconstruction and the resolution of diffraction blurred images.
One-step non-chromatography purification of a low abundant fucosylated protein from complex plant crude extract

Effective methods for isolation and purification of glycoproteins and other glycoconjugates are important to biopharmaceutical industry and diagnostic industry. They are also critical to an emerging field of glycoproteomics. In this work, we applied the newly-developed affinity ligand, a fusion protein of elastic like polymer (ELP) and a bacterial lectin, in an affinity precipitation process to purify soybean peroxidase (SBP) based on the presence of fucoseon the protein surface. We addressed, in particular, the challenge of purifying a low abundant protein from a complex dilute crude plant extract. The novel affinity precipitation developed in this work was very promising. One step binding and precipitation resulted in >95% recovery yield directly from crude extract and a 22.7 fold purification, giving a specific activity of 420 U/mg. The SBP isolated using this affinity precipitation meets or exceeds the quality specifications of reagent grade products by Sigma. We showed that the recovery yield had a strong dependence on the molar ratio of ligand to target fucosylated protein, with a ratio of three giving nearly full recovery, which could be predicted based on the total fucose content per protein molecule and the number of binding site per ligand molecule. We additionally developed a method of ligand regeneration and investigated its reuse. A simple wash with pH buffer was shown to be effective to regenerate the binding capacity for the ligand, and the ligand could be used for 10 times, giving an averaged 80% isolation yield based on initial input of soybean peroxidase. Taken together, an effective method of affinity precipitation was developed, which could be used to enrich a low abundant target glycoprotein from a complex mixture with a high recovery yield. The high selectivity for fucosylated protein and its ease of operation make this method particularly useful for purification of low abundant glycoprotein from natural sources. This work establishes a non-chromatography glycoform-specific purification method and extends the useful ELP-based affinity precipitation to glycoproteins.
High-bandwidth radio frequency Coulter counter

We demonstrate a method for high-bandwidth, high-sensitivity particle sensing and cell counting in a microfluidic system. Our approach employs a tuned radiofrequency probe, which forms the radiofrequency analog of a Coulter counter. By measuring the reflected rf power, this approach provides an unprecedented detection rate, with a theoretical bandwidth in excess of 10 MHz. Particle detection was performed in a continuous flow mode in a microfluidic channel, using 15μm diameter polystyrene beads suspended in a sucrose-saline solution. We demonstrate 30 kHz counting rates and show high-resolution bead time-of-flight data, comprising the fastest electronic particle detection on-chip to date.

Phase change materials for thermal stabilization of composite thermistors

The objective of this investigation was to develop a triphasic PTC thermistor composite which incorporated a phase capable of absorbing heat at a critical temperature, and thus limiting deleterious effects associated with thermal runaway. The system chosen for study was pentaerythritol incorporated into a carbon black–polyethylene thermistor system. Pentaerythritol exhibits a first order tetragonal to cubic phase transition at 185 °C, with a 1.87 to 3.18 J/°C · g change in specific heat and a 425 J/cm3 heat of transition. Composites with room temperature resistivities as low as 0.1 Ω · m, a PTCR effect of up to six orders of magnitude, and reproducible temperature-cycling behavior were developed. The pentaerythritol introduced thermal delays up to 7 min at 185 °C and substantially increased the electrical and mechanical stability of the composites with temperature and voltage cycling. High fields imparted irreversible effects in these composites as reflected by an increase in the room temperature and high temperature resistivity.
Chemical nature of alkali-promoted copper-cobalt-chromium oxide higher alcohol catalysts

Abstract The chemical nature of alkali-promoted copper-cobalt-chromium higher alcohol catalysts has been evaluated as a function of calcination temperature by using X-ray diffraction and X-ray photoelectron spectroscopy. Also investigated were the alkali-promoted mono- and bimetallic oxide systems. The activated catalyst was determined to consist of copper metal and a cobalt-chromium spinel. Oxygenate production correlated with the dispersion of copper metal in the catalyst. Poorer copper dispersion and a decrease in oxygenate formation were observed with increasing catalyst calcination temperature. There was no evidence of cuprous ions or cobalt metal in the activated catalyst; therefore, it is unlikely that component synergism is a result of alkyl chain growth on cobalt metal sites coupled with alcohol termination by CO molecularly adsorbed on Copper(I) chromite.
Acid mucopolysaccharides in cardiac intracavitary tumors

Three left atrial myxomas and one myxosarcoma were analysed and studied in tissue culture. The myxomas contained 0.2% mucopolysaccharide (wet weight) which on fractionation yielded hyaluronic acid 22%, chondroitin sulfate 30%, chondroitin 47%, and dermatan sulfate <1%. On incubation of the explants there was rapid growth of cells and gelling of the culture medium. The later has never been observed in the culture of various human tissues including those of cardiac origin. electronmicroscopy showed abundant collagen fibers, which may be responsible for the gelformation. Hyaluronic acid was the major component of the culture medium. Analysis of the myxosarcoma revealed high molecular weight hyaluronic acid as the only polysaccharide. These striking differences in composition might be specific for the two types of tumors. Sera from two patients with myxomas and one patient with myxosarcoma revealed a five-fold increase of mucopolysaccharide. Following the surgical removal of the tumors the serum mucopolysaccharide returned to normal in all three patients.
