One-dimensional impenetrable anyons in thermal equilibrium: III. Large distance asymptotics of the space correlations

Using the determinant representation for the field–field correlation functions of impenetrable anyons at finite temperature obtained in [1], we derive a system of nonlinear partial differential equations completely characterizing the correlators. The system is the same as the one for impenetrable bosons but with different initial conditions. The large-distance asymptotic behavior of the correlation functions is obtained from the analysis of the Riemann–Hilbert problem associated with the system of differential equations. We calculate both the exponential and pre-exponential factors in the asymptotics of the field–field correlators. The asymptotics derived in this way agree with those of the free fermions and impenetrable bosons in the appropriate limits, κ → 1 and κ → 0, of the statistics parameter κ, and coincide with the predictions of the conformal field theory at low temperatures.
Spinal fractures and/or spinal cord injuries are associated with orthopedic and internal organ injuries in proximity to the spinal injury

Abstract Background the demographics, mechanisms of injury, and concurrent injuries associated with cervical, thoracic and lumbar spinal fracture and/or spinal cord injury remain poorly characterized. Methods Patients aged 18 and older with spinal injury between 2011 and 2015 in the National Trauma Data Bank (NTDB) were identified. Patient demographics, comorbidity burden, mechanism of injury, and associated injuries were analyzed. Results in total, 520,183 patients with acute spinal injury were identified including 216,522 cervical, 191,218 thoracic, and 220,294 lumbar. The age distributions were trimodal with peaks in incidence at around 2155 and a lesser peak around 85 years of age. The number of comorbidities increased while injury severity decreased with advancing patient age. Motor vehicle accidents (MVAs) were the most common mechanism of injury. Associated bony and internal organ injuries were common and occurred in 63% of cervical spine injury patients, 79% of thoracic spine injury patients, and 71% of lumbar spine injury patients. In all three sub-populations, there was a predominance of injuries in the local area of the primary injury. For cervical, these were rib injuries (28%), thoracic spine injuries (22%), skull fractures (20%), intracranial injuries (26%) and lung injuries (21%). For thoracic, these were rib injuries (47%), lumbar spine injuries (26%), cervical spine injuries (25%), lung injuries (35%) and intracranial injuries (24%). For lumbar, these were rib injuries (38%), thoracic spine injuries (22%), pelvic fractures (20%), lung injuries (26%) and intracranial injuries (19%). Multivariate regression analysis demonstrated that increased injury severity was strongly correlated with increased mortality, with lesser contributions from increased age and comorbidity burden. Conclusions the current study revealed spinal fractures and/or cord injuries had high incidences of associated injuries that had a predominance of local distribution. These findings, in combination with the mortality analysis, demonstrate the importance of local targeted evaluations for associated injuries.

Providers PrEP: Identifying Primary Health care Providers' Biases as Barriers to Provision of Equitable PrEP Services.

Background Despite their disparately high HIV incidence and voiced willingness to use pre-exposure prophylaxis (PrEP), Black cisgender women's knowledge and uptake of PrEP are low, especially relative to White cisgender women and men who have sex with men. Mounting evidence demonstrates that health care provider recommendations are a critical factor in women's awareness, willingness, and ability to uptake PrEP. Health care providers may make clinical judgments about who is (not) a good candidate for PrEP based on unconscious and conscious stereotypes and prejudice. Setting We conducted an online experiment among N = 160 health care providers with prescribing privileges in the 48 HIV hotspot counties. Method Providers received 1 of 4 vignettes about a PrEP eligible woman. Vignettes varied by patient race and substance use status. Then, providers reported their willingness to discuss PrEP with the patient and willingness to prescribe PrEP to her. Results We tested 2 models predicting providers (1) willingness to discuss and (2) willingness to prescribe PrEP, contingent on their racial attitudes. Providers who scored high on a modern racism measure were less willing to discuss and prescribe PrEP to the Black patient. These effects were mediated by provider perceptions of patients' abilities to adhere to PrEP, but not their expectations of risk compensatory behaviors. Conclusions Our findings highlight the importance of applying an intersectional lens in documenting the processes that exacerbate inequities in PrEP use. This study provides evidence to support the development of interventions that address the mechanisms that work to thwart optimal care.
B cell expression of the SH2-containing inositol 5-phosphatase (SHIP-1) is required to establish anergy to high affinity, proteinacious autoantigens.

Many self-reactive B cells exist in the periphery in a rapidly reversible state of unresponsiveness referred to as anergy. Reversibility of anergy indicates that chronically occupied BCR must transduce non-durable regulatory signals that maintain unresponsiveness. Consistent with such a mechanism, studies of immunoglobulin transgenic, as well as naturally occurring polyclonal autoreactive B cells demonstrate activation of the inositol 5-phosphatase SHIP-1 in anergic cells, and low affinity chromatin autoantigen-reactive B cells have been shown to require expression of this phosphatase to maintain anergy. However, it has been reported that anergy of B cells recognizing high affinity soluble antigen may not require SHIP-1, and is instead mediated by upregulation of the inositol 3-phosphatase PTEN. To further explore this apparent difference in mechanism we analyzed the effect of B cell-targeted SHIP-1 deletion on immune tolerance of high affinity anti-HEL B cells in mice expressing soluble HEL (MD4.ML-5). We report that SHIP-1 functions to dampen responses of naive and low-dose antigen-primed B cells in vitro, and is required for induction of B cell tolerance. Thus, while anergy of B cells reactive with low affinity and likely polyvalent chromatin antigens is maintained by activation of inhibitory signaling circuitry involving SHIP-1, anergy of B cells recognizing soluble self antigen with high affinity also requires increased activity of SHIP-1.
SU-F-BRB-05: Collision Avoidance Mapping Using Consumer 3D Camera

Purpose: To develop a fast and economical method of scanning a patient’s full body contour for use in collision avoidance mapping without the use of ionizing radiation. Methods: Two consumer level 3D cameras used in electronic gaming were placed in a CT simulator room to scan a phantom patient set up in a high collision probability position. A registration pattern and computer vision algorithms were used to transform the scan into the appropriate coordinate systems. The cameras were then used to scan the surface of a gantry in the treatment vault. Each scan was converted into a polygon mesh for collision testing in a general purpose polygon interference algorithm. All clinically relevant transforms were applied to the gantry and patient support to create a map of all possible collisions. The map was then tested for accuracy by physically testing the collisions with the phantom in the vault. Results: The scanning fidelity of both the gantry and patient was sufficient to produce a collision prediction accuracy of 97.1% with 64620 geometry states tested in 11.5 s. The total scanning time including computation, transformation, and generation was 22.3 seconds. Conclusion: Our results demonstrate an economical system to generate collision avoidance maps. Future work includes testing the speed of the framework in real-time collision avoidance scenarios. Research partially supported by a grant from Varian Medical Systems
Sharing-Aware Online Algorithms for Virtual Machine Packing in Cloud Environments

Cloud service providers offer services to a large number of users by employing virtualization technologies. One of the challenges faced by the cloud providers using virtualized environments is the development of efficient algorithms for assigning Virtual Machine (VM) instances to servers such that the number of hosting servers is minimized. This is also known as the problem of VM Packing. In this paper, we design a family of sharing-aware online algorithms for solving the VM Packing problem that take into account the sharing of memory among collocated VMs. We introduce a new server resource scarcity metric which establishes an order among servers that are suitable for hosting an arriving VM request and use it in the design of the algorithms. We evaluate the performance of our sharing-aware online algorithms by performing an extensive set of experiments comparing them against several existing sharing-oblivious VM packing algorithms.

Incorporating Yield Information from a Biogeochemical Model into an Agricultural Production Model to Infer Adoption of a New Bioenergy Crop

Positive Mathematical Programming (PMP) models of agricultural supply have been popularised by Howitt (1995b) and used extensively in policy analysis, to predict the response of agricultural systems facing resource, technology and policy constraints to exogenous shocks. The models are typically calibrated against observed regional—e.g., in the U.S., county-level or state-level—cropping patterns and input allocations, under the maintained assumption of profit-maximising behavior.
Creating a story-telling universe

Extended story generation, such as the creation of soap opera stories, is a difficult and interesting problem for Artificial Intelligence. We present here the first phase of the development of a program, UNIVERSE, to tell such stories. In particular, we introduce a method for creating universes of characters appropriate for extended story generation. This method concentrates on the need to keep story-telling universes consistent and coherent. We describe "the information that must be maintained for characters and interpersonal relations, and the use of stereotypical information about people to help motivate trait values.
Dopamine transporter genotype and stimulant dose-response in youth with attention-deficit/hyperactivity disorder.

Abstract Objectives: This study seeks to determine if variation in the dopamine transporter gene (SLC6A3/DAT1) moderates the dose-response effects of long-acting dexmethylphenidate (D-MPH) and mixed amphetamine salts (MAS) in children with attention-deficit/hyperactivity disorder (ADHD). Methods: Fifty-six children and adolescents (mean age=11.7±2.2) participated in a double-blind, two period crossover, dose-response study with a randomized placebo week in each 4 week drug period. Each period consisted of sequential week-long exposures to three dose levels (10, 20, 25–30 mg, depending upon weight) of D-MPH or MAS. Results: Doses of 10–20 mg of either D-MPH or MAS had little to no effect on hyperactivity-impulsivity and total ADHD symptom scores in subjects with the 9/9 genotype; this was in contrast to the dose-response curves of subjects with either the 10/10 or 10/9 genotype. Conclusions: ADHD youth with the 9/9 genotype may require higher stimulant doses to achieve adequate symptom control.
Lumbar paraspinal muscle transverse area and symmetry in dogs with and without degenerative lumbosacral stenosis.

OBJECTIVES To investigate whether dogs with degenerative lumbosacral stenosis have decreased lumbar paraspinal muscle transverse area and symmetry compared with control dogs. MATERIALS AND METHODS Retrospective cross-sectional study comparing muscles in transverse T2-weighted magnetic resonance images for nine dogs with and nine dogs without degenerative -lumbosacral stenosis. Mean transverse area was measured for the lumbar multifidus and sacrocaudalis dorsalis lateralis muscles bilaterally and the L7 vertebral body at the level of the caudal endplate. Transverse areas of both muscle groups relative to L7 and asymmetry indices were compared between study populations using independent t tests. RESULTS Mean muscle-to-L7 transverse area ratios were significantly smaller in the degenerative lumbosacral stenosis group compared with those in the control group in both lumbar multifidus (0·84 ±0·26 versus 1·09 ±0·25; P=0·027) and sacrocaudalis dorsalis lateralis (0·5 ±0·15 versus 0·68 ±0·12; P=0·005) muscles. Mean asymmetry indices were higher for both muscles in the group with degenerative lumbosacral stenosis than in the control group, but highly variable and the difference was not statistically significant. CLINICAL SIGNIFICANCE These findings suggest that dogs with degenerative lumbosacral stenosis have decreased lumbar paraspinal muscle mass that may be a cause or consequence of the -syndrome. Understanding altered paraspinal muscle characteristics may improve understanding of the -pathophysiology and management options for degenerative lumbosacral stenosis.

Regulation of the T-cell receptor delta enhancer by functional cooperation between c-Myb and core-binding factors.

Abstract A T-cell-specific transcriptional enhancer lies within the J delta 3-C delta intron of the human T-cell receptor (TCR) delta gene. The 30-bp minimal enhancer element denoted delta E3 carries a core sequence (TGTGGTTT) that binds a T-cell-specific factor, and that is necessary but not sufficient for transcriptional activation. Here we demonstrate that the transcription factor c-Myb regulates TCR delta enhancer activity through a binding site in delta E3 that is adjacent to the core site. Both v-Myb and c-Myb bind specifically to delta E3. The Myb site is necessary for enhancer activity, because a mutation that eliminates Myb binding abolishes transcriptional activation by the delta E3 element and by the 370-bp TCR delta enhancer. Transfection of cells with a c-Myb expression construct upregulates delta E3 enhancer activity, whereas treatment of cells with an antisense c-myb oligonucleotide inhibits delta E3 enhancer activity. Since intact Myb and core sites are both required for delta E3 function, our data argue that c-Myb and core binding factors must cooperate to mediate transcriptional activation through delta E3. Efficient cooperation depends on the relative positioning of the Myb and core sites, since only one of two overlapping Myb sites within delta E3 is functional and alterations of the distance between this site and the core site disrupt enhancer activity. Cooperative regulation by c-Myb and core-binding factors is likely to play an important role in the control of gene expression during T-cell development.
FACTORS ASSOCIATED WITH ADOLESCENTS' COMPLIANCE WITH THE HEPATITIS B VACCINATION SERIES. • 24

Objective: To determine the compliance among adolescents and measure the associations of various demographic and behavioral factors with compliance with a standard hepatitis B vaccination series. Design: Eight hundred twenty six patients from a hospital-based adolescent medicine clinic were enrolled. The participants received a standardized education about hepatitis B and the immunization schedule (0,1, and 6 months) and filled out questionnaires investigating demographic factors, risk behaviors, risk factors for obtaining hepatitis B, medication use, chronic illnesses, and experience, knowledge and attitudes about hepatitis B and the immunization series. They then received their first hepatitis B vaccination. Compliance is being followed and is defined as having received the second vaccine within 61 days and the third vaccine within 274 days of enrollment. The associations between the dependent and independent variables were measured using chi square analysis with Mantel-Haentszel test for trend for ordinal covariates, followed by a stepwise logistic regression analysis. Results: 28.5% are male. 18.5% are white, 45.6% black, 20.4% Hispanic, 1.4% Asian, 14.2% other. 18.5% are self-pay, 33.4% Medicaid, 9.7% free care, 38.4% private insurance. The age range of patients is 11.1-24.9 years. 49.9% were compliant with the second vaccine. 46.7% of those who could have been compliant with vaccination 3 were compliant. Factors associated with compliance with the second vaccine on bivariate analysis are female gender (P<0.001), white race (P<0.001), presence of an eating disorder (P=0.043), knowledge that hepatitis B is sexually transmitted (P=0.015), increased travel time to the clinic (P=0.029), the use of birth control pills (P=0.002) and vitamins (P=0.048), knowing someone who had received the series (P=0.018), and academic achievement(P=0.030). Factors associated with noncompliance include Medicaid(P<0.001), marijuana use (P=0.020), and cocaine use (P=0.048). Logistic regression modeling reveals that the covariates with compliance are white race(OR=3.84, 95% CI=2.47-5.96), female gender (OR=1.70, CI=1.20-2.40), knowledge that hepatitis B is sexually transmitted (OR=2.16, CI=0.91-5.12), and self-reported academic achievement (OR=1.12, CI=1.00-1.26).Conclusion: 49.9% of adolescents are compliant with the dosing schedule for the second hepatitis B vaccination. Knowledge of factors related to noncompliance may facilitate targeted interventions for reaching teens at risk.
Insulin resistance and exercise capacity in male children and adolescents with non-alcholic fatty liver disease.

Insulin resistance (IR) and obesity may be associated with impaired response to physical exercise. We aimed at assessing physical capacity in obese children with biopsy proven non-alcoholic fatty liver disease (NAFLD) as compared to normal weight and obese children without fatty liver disease. All male subjects, 20 NAFLD and 31 control individuals (20 obese, without NAFLD and 11 normal weight children) took part in the study. We evaluated changes in cardiovascular parameters during a bicycle–ergometer exercise test (James’ test). Duration, power of exercise, heart rate (HR), blood pressure (BP), pulse pressure, cardiac output (ICO) and total peripheral vascular resistance indexed for height (ITPVR) were recorded at rest (r) and peak (p) exercise. The homeostatic model assessment was used to determine insulin resistance (HOMA-IR) and beta-cell action (HOMA-beta cell). In NAFLD and obese subjects, fasting leptin, insulin secretion, insulinogenic index (IGI), muscle insulin sensitivity (MISI) and hepatic insulin resistance index (HIRI) were assayed. Children with NAFLD were the most insulin-resistant (P = 0.001), and showed higher HIRI than obese controls (P = 0.05). At rest, they had the lowest values of SBPr (P = 0.001 vs. controls and P ≤ 0.05 vs. obese controls); during the test, the highest values of ICOp (P = 0.005), ΔICO (P = 0.003) and ΔTRVPp (P ≤ 0.0001). NAFLD and obese controls both had impaired ΔHRp (P ≤ 0.0001). However, obese controls were not able to reduce peripheral resistance during the test. HOMA-IR explained 28% of variance in ΔICO of the whole sample, (P ≤ 0.0001). In obese children with or without NAFLD, increased IR and body weight may induce cardiovascular compensatory changes in response to physical exercise with fairly different pathogenetic mechanisms, which are likely to be dependent on the different degree of IR.
Power mapping and modeling of multi-core processors

We propose new techniques for post-silicon power mapping and modeling of multi-core processors using infrared imaging and performance counter measurements. An accurate finite-element modeling framework is used to capture the relationship between temperature and power, while compensating for the artifacts introduced from substituting traditional heat removal mechanisms with oil-based infrared-transparent cooling mechanisms. We use thermal conditioning techniques to build leakage power models for the die. Utilizing the power maps identified from infrared mapping, we develop empirical power models for different processor blocks based on the measurements from the performance monitoring counters (PMCs), and utilize the PMC-based models to analyze the transient power consumption. In our experiments, we capture thermal images from a quad-core processor under different workload conditions, and then we reconstruct the dynamic and leakage power maps for different blocks. Our results show good accuracy in mapping and modeling, revealing good insights into the trends of power consumption in multi-core processors.
A Modified Simon-Lewin Reaction: N-Nitrosamines as Intermediates in the Reaction of Secondary Amines With Nitroprusside and Acetaldehyde

Abstract Secondary aliphatic amines give a blue color with sodium nitroprusside and acetaldehyde in aqueous solution at pH 10. A closely analogous reaction of N-nitrosamines has been discovered. Aliphatic N-nitrosamines can give a similar blue color with a secondary aliphatic amine, sodium pentacyanoaquoferrate (II) and acetaldehyde at pH 10. This suggests strongly that N-nitrosamines are intermediates in the corresponding nitroprusside reaction. The new reaction may also have some value as a color test for N-nitrosamines.
A Proof of Part of Haldane’s Conjecture on Spin Chains

It has been argued that the spectra of infinite length, translation and U(1) invariant, anisotropic, antiferromagnetic spin s chains differ according to whether s is integral or 1/2 integral: There is a range of parameters for which there is a unique ground state with a gap above it in the integral case, but no such range exists for the 1/2 integral case. We prove the above statement for 1/2 integral spin. We also prove that for all s, finite length chains have a unique ground state for a wide range of parameters. The argument was extended to SU(n) chains, and we prove analogous results in that case as well.
Steady state oscillations and stability of non-linear dynamic vibration absorbers

Abstract The first part of this study presents an analysis for determining the steady state response of dynamic vibration absorbers, for which both the machine and the absorber are assumed to possess a non-linear, Duffing type, stiffness. A procedure which analyzes the stability characteristics of the located periodic steady state solutions is also developed. In the second part, this analysis is applied and numerical results are obtained for several combinations of the system parameters, in an effort to gain a better understanding of the effect of these parameters on the system response. Utilizing information from the amplitude of the solutions obtained, as well as their stability characteristics, it is shown that proper selection of the system parameters results in substantial improvements of the technical performance of non-linear absorbers and avoids dangerous effects that are possible to occur due to the presence of the non-linearities.
Effect of a physician-directed educational campaign on performance of proper diabetic foot exams in an outpatient setting.

BACKGROUND: The established guidelines for a diabetes foot examination include assessing circulatory, skin, and neurological status to detect problems early and reduce the like-lihood of amputation. Physician adherence to the guidelines for proper examination is less than optimal. OBJECTIVE: Our objective was to increase compliance with the performance of a proper foot examination through a predominantly physician-directed interventional campaign. METHODS: The study consisted of 3 parts: a retrospective chart review to estimate background compliance, an educational intervention, and prospective chart review at 3 and 6 months. A properly documented foot examination was defined as assessing at least 2 of the 3 necessary components. The educational intervention consisted of 2 lectures directed at resident physicians and a quality assurance announcement at a general internal medicine staff meeting. Clinic support staff were instructed to remove the shoes and socks of all diabetic patients when they were placed in exam rooms, and signs remiding diabetics were placed in each exam room. RESULTS: There was a significant increase in the performance of proper foot examination over the course of the study (baseline 14.0%, 3 months 58.0%, 6 months 62.1%; P<.001). Documentation of any component of a proper foot examination also increased substantially (32.6%, 67.3%, 72.5%; P<.001). Additionally, performance of each component of a proper exam increased dramatically during the study: neurological (13.5%, 35.8%, 38.5%; P<.001), skin (23.0%, 64.2%, 69.2%; P<.001), and vascular (14.0%, 51.2%, 50.5%; P<.001). CONCLUSIONS: Patients with diabetes are unlikely to have foot examinations in their primary medical care. A simple, lowcost educational intervention significantly improved the adherence to foot examination guidelines for patients with diabetes.
Pointlike sets: the finest aperiodic cover of a finite semigroup

The research in this paper is motivated by the open question: “Is the complexity of a finite semigroup S decidable?” Following the lead of the Presentation Lemma (Rhodes), we describe the finest cover on S that can be computed using an aperiodic semigroup and give an explicit relation. The central idea of the proof is that an aperiodic computation can be described by a new ‘blow-up operator’ Hω. The proof also relies on the Rhodes expansion of S and on Zeiger coding.
Structure-function relationship of the extracellular calcium-sensing receptor.

The extracellular calcium (Ca2+ o)-sensing receptor (CaR), originally cloned from bovine parathyroid, is a G protein-coupled receptor (GPCR) (1). The CaR is expressed on the plasma membrane of a variety of cell types, including those involved in maintaining systemic calcium homeostasis, such as parathyroid chief cells, renal cells, as well as thyroid C-cells, and those not participating in systemic calcium homeostasis, such as brain and breast cells (2). The CaR is well conserved across species (3, 4, 5, 6, 7, 8). For instance, the amino acid sequences of CaRs from human, rat, and rabbit are more than 90% identical to that of the bovine CaR.
Randomized trial to compare perioperative outcomes of Filshie clip vs. Pomeroy technique for postpartum and intraoperative cesarean tubal sterilization: a pilot study.

Abstract Objective To compare, by conducting a randomized trial, Filshie clip and Pomeroy techniques for postpartum and intrapartum cesarean sterilizations in a United States teaching hospital with respect to surgeon preference and perioperative outcomes. Method Thirty-two obstetric patients consented for sterilization were randomized to Pomeroy technique or Filshie clip placement. Following the surgical procedure, surgeons and operating room technicians completed a survey regarding their experience with the procedures and preference. Patient demographic data, time for procedure and follow-up visits were obtained by chart review. Results For most postpartum sterilizations, the mean duration of the procedure was almost 7 min faster for the Filshie clip technique (p = 0.08); perioperative outcomes were equivalent (p = 0.05). Application of the Filshie clip was rated easier than Pomeroy suture application and, overall, the Filshie clip sterilization procedure was rated less difficult (p = 0.03). Seventy percent of surgeons preferred the Filshie clip technique and would choose it if only one postpartum sterilization method was available. Conclusion For obstetric sterilization, surgeons preferred the Filshie clip over the Pomeroy technique. In addition, operating time was shorter for the Filshie clip. This pilot study suggests that use of the Filshie clip technique has the potential to establish a new standard of care for postpartum and intrapartum cesarean sterilization.
Improvement of electric power system load forecasting and operational planning for control automation

A Pore-Network Model For Foam Formation And Propagation in Porous Media

We present a pore-network model, based on a pores-and-throats representation of the porous medium, to simulate the generation and mobilization of foams in porous media. The model allows for various parameters or processes, empirically treated in current models, to be quantified and interpreted. Contrary to previous works, we also consider a dynamic (invasion) in addition to a static process. We focus on the properties of the displacement, the onset of foam flow and mobilization, the foam texture and the sweep efficiencies obtained. The model simulates an invasion process, in which gas invades a porous medium occupied by a surfactant solution. The controlling parameter is the snap-off probability, which in turn determines the foam quality for various size distributions of pores and throats. For the front to advance, the applied pressure gradient needs to be sufficiently high to displace a series of lamellae along a minimum capillary resistance (threshold) path. We determine this path using a novel algorithm. The fraction of the flowing lamellae, X{sub f} (and, consequently, the fraction of the trapped lamellae, X{sub f}) which are currently empirical, are also calculated. The model allows the delineation of conditions tinder which high-quality (strong) or low-quality (weak) foams form. In eithermore » case, the sweep efficiencies in displacements in various media are calculated. In particular, the invasion by foam of low permeability layers during injection in a heterogeneous system is demonstrated.« less
CeCu5−xIn1+x[x= 0.17 (1)] with the orthorhombic CeCu6structure

Large single crystals of the title compound, cerium copper indium, were synthesized from the elements using a eutectic Cu/In mixture as a solvent. CeCu5−xIn1+x [x = 0.17 (1)] is a new ternary derivative of the orthorhombic CeCu6 structure type [space group Pnma (No. 62)]. This result differs from that of Kalychak, Baranyak, Belsky & Dmytrakh [Dopl. Akad. Nauk Ukr. RSR Ser. B (1988). 9, 39–42], who found that CeCu4.38In1.62 belongs to a new structure type (space group Pnnm), derived from the parent CeCu6 compound by doubling the a axis. In the present structure, all the atoms, except one of the Cu species, occupy special positions with mirror symmetry.
Quality infant day-care and grade school behavior and performance

Relations between attendance in stable high-quality day-care programs and grade school behavior and performance were determined using 2 longitudinal data sets. The first sample included grade school children who had received stable, full-time infant day-care and preschool day-care until they reached school age in the same high-quality day-care center. In this sample the amount of time (months) spent in full-time center care was positively related to the number of friends and extracurricular activities of the children. In addition, more time in the center was positively related to parents' ratings of the children's emotional well-being, leadership, popularity, attractiveness, and assertiveness and negatively related to aggressivity. Study 2 sampled sixth graders who had also received varying amounts (months) of stable full-time day-care, but this group attended a variety of quality day-care centers. In this sample the amount of time in day-care was related to the teachers' ratings of their emotional well-being, attractiveness, and assertiveness. In addition, children with more time in high-quality day-care showed more physical affection during peer interactions, were more often assigned to the gifted program, and received higher math grades.

Perturbed Kuhn-Tucker points and rates of convergence for a class of nonlinear-programming algorithms

This paper establishes quantitative bounds for the variation of an isolated local minimizer for a general nonlinear program under perturbations in the objective function and constraints. These bounds are then applied to establish rates of convergence for a class of recursive nonlinear-programming algorithms.
Membrane docking geometry and target lipid stoichiometry of membrane-bound PKCα C2 domain: a combined molecular dynamics and experimental study.

Protein kinase Cα (PKCα) possesses a conserved C2 domain (PKCα C2 domain) that acts as a Ca2+-regulated membrane targeting element. Upon activation by Ca2+, the PKCα C2 domain directs the kinase protein to the plasma membrane, thereby stimulating an array of cellular pathways. At sufficiently high Ca2+ concentrations, binding of the C2 domain to the target lipid phosphatidylserine (PS) is sufficient to drive membrane association; however, at typical physiological Ca2+ concentrations, binding to both PS and phosphoinositidyl-4,5-bisphosphate (PIP2) is required for specific plasma membrane targeting. Recent EPR studies have revealed the membrane docking geometries of the PKCα C2 domain docked to (i) PS alone and (ii) both PS and PIP2 simultaneously. These two EPR docking geometries exhibit significantly different tilt angles relative to the plane of the membrane, presumably induced by the large size of the PIP2 headgroup. The present study utilizes the two EPR docking geometries as starting points for molecular dynamics simulations that investigate atomic features of the protein-membrane interaction. The simulations yield approximately the same PIP2-triggered change in tilt angle observed by EPR. Moreover, the simulations predict a PIP2:C2 stoichiometry approaching 2:1 at a high PIP2 mole density. Direct binding measurements titrating the C2 domain with PIP2 in lipid bilayers yield a 1:1 stoichiometry at moderate mole densities and a saturating 2:1 stoichiometry at high PIP2 mole densities. Thus, the experiment confirms the target lipid stoichiometry predicted by EPR-guided molecular dynamics simulations. Potential biological implications of the observed docking geometries and PIP2 stoichiometries are discussed.
Chromosome 1p and 19q deletions in glioblastoma multiforme.

Context Deletions on chromosomes 1p and 19q have been shown to correlate with prognosis and chemosensitivity in anaplastic oligodendrogliomas. In glioblastoma multiforme (GBM), the impact on prognosis of these alterations in GBM is unclear. Objective The purpose of this study was to identify patients with GBM who had evidence of 1p or 19q deletions by fluorescence in situ hybridization, and correlate these results with clinical findings and survival. Design Three hundred thirty-seven GBM resected between 2001 and 2006 were evaluated using fluorescence in situ hybridization to identify deletions on chromosomes 1p and 19q. Cox regression was used to compare survival between these 2 groups and a control group of 1p and 19q intact tumors. Result Seventeen (5.1%) patients (9 males; mean age at diagnosis=61 y, range: 35 to 84 y) were found to have 1p deletions; 8 patients (47.1%) received chemotherapy and 13 patients received radiation therapy. The mean survival for this group was 10.8 months (range: 1 to 50 mo). Eighteen (5.3%) patients (11 females; mean=56 y, range: 25 to 76 y) had 19q deletions; 9 patients (50%) received chemotherapy and 8 patients were known to have had radiation therapy. The mean survival of this group was 8.4 months (range: 1 to 17 mo). A control group of 20 patients (13 males; mean=60 y, range: 40 to 80 y) was selected, 8 patients (40%) of who received chemotherapy and 12 patients were known to have had radiation therapy. The mean survival in this group was found to be 16.4 months (1 to 59 mo). Nine (3.7%) tumors had codeletions of 1p and 19q and were not evaluated in this study. Isolated 1p and 19q deletions did not significantly correlate with survival. Adjusting for sex, age, and chemotherapy, the 19q-deleted group had a significantly lower survival (hazard ratio =2.8, P=0.025) than the other groups. Conclusions The incidence of isolated 1p or 19q deletions among GBM in the current study was 6.2% and 5.3%, respectively. In contrast to anaplastic oligodendrogliomas, 1p and 19q deletions alone were not found to improve survival of patients with GBM; however, when adjusted for age, sex, and chemotherapy, 19q deletions seem to negatively impact survival.
WHAT A SHORT, STRANGE TRIP IT’S BEEN: MOVING FORWARD AFTER FIVE YEARS OF MARCELLUS SHALE DEVELOPMENT

Legal and policy issues surrounding the extraction of natural gas from the Marcellus Shale Formation are at the forefront of public dialogue in Pennsylvania today. Depending on one’s individual perspective, Marcellus Shale natural gas drilling may connote thoughts of regional economic development, energy independence, personal wealth, fractured landscapes, or polluted waters. Friends and foes of drilling alike have devoted extensive 1
Incremental validity of the structured interview for the five-factor model of personality (SIFFM)

This study examined the incremental validity of the Structured Interview for the Five-Factor Model (SIFFM; Trull & Widiger, 1997) scores in the prediction of borderline, antisocial, and histrionic personality disorder symptoms above and beyond variance accounted for by scores from the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993), a self-report questionnaire that includes items relevant to both normal (i.e. Big Three) and abnormal personality traits. Approximately 200 participants (52 clinical outpatients, and 149 nonclinical individuals from a borderline-features-enriched sample) completed the SIFFM, the SNAP, and select sections of the Personality Disorder Interview—IV (PDI-IV; Widiger, Mangine, Corbitt, Ellis, & Thomas, 1995). We found support for the incremental validity of SIFFM scores, further indicating the clinical utility of this instrument. However, results also supported the incremental validity of SNAP scores in many cases. We discuss the implications of the findings in terms of dimensional approaches to personality disorder assessment. Copyright © 2005 John Wiley & Sons, Ltd.
Opaque minerals in lunar samples.

Microscope study and electron microprobe analysis of lunar rocks and soil show that ilmenite, troilite, and native iron are accompanied by trace amounts of ulvospinel, titanochromite (new mineral name), an unidentified Ti-Fe oxide, and a complex Zr-Y silicate. The assemblage requires a strongly reducing environment. Textures and modal proportions show that the rocks present are not a differentiation series. The restricted nature of the opaque mineral assemblage suggests a narrow range of composition for the materials from which the parent liquids of the rocks were generated. Textural variety mnust reflect differences in cooling rates, probably related to depths of formation.
Enhanced Targeted Initial Populations for Multiobjective Product Line Optimization

Initial populations for genetic algorithms are often created using randomly generated designs in an effort to maximize the genetic diversity in the design space. However, research indicates that the inclusion of solutions generated based on domain knowledge (i.e. non-random solutions) can notably improve the performance of the genetic algorithm with respect to solution performance and/or computational cost for convergence. This performance increase is extremely valuable for computationally expensive problems, such as product line optimization. In prior research, the authors demonstrated these improvements for product line design problems where market share of preference was the performance objective. Initial product line solutions were constructed from products that had the largest product-level utility for individual respondents. However, this simple product identification strategy did not adequately scale to accommodate the richer design problem associated with multiple objectives. This paper extends the creation of targeted initial populations to multiobjective product line design problems by using the objectives of the problem, instead of product level utility, to identify candidate designs. A MP3 player and vehicle feature packaging product line design problems are used to demonstrate this approach and assess the improvement of this modification.Copyright © 2013 by ASME
Mitochondrial and nuclear inheritance in an androgenetic line of rainbow trout, Oncorhynchus mykiss.

Abstract Mitochondrial and nuclear inheritance of clonal rainbow trout produced by androgenesis were evaluated using DNA sequencing and amplified fragment length polymorphism (AFLP) analysis. All individuals were propagated using sperm from a single OSU clonal line sex inversed female crossed with multiple egg sources whose nuclear material was destroyed using Cobalt 60 gamma radiation. A heat shock was administered to developing haploid embryos to prevent the first cleavage and restore diploidy. Sequencing of 4713 continuous base pairs was performed on four rainbow trout and one cutthroat trout mitochondrial haplotypes spanning the ND 5 protein subunit of Complex I through the control region. Total sequence variation between haplotypes ranged from 0.34% to 6.14% with rainbow trout haplotype variation between 0.34% and 0.85%. No evidence was found to indicate point mutations associated with irradiation. DNA sequence for coded proteins was converted to amino acid sequence using the standard mammalian mitochondrial code to determine conservative and non-conservative amino acid substitutions. Total amino acid variation ranged between 0.60% and 3.10% with rainbow trout haplotype variation from 0.60% to 1.12% with non-conservative amino acid substitutions present between all mitochondrial haplotypes. AFLP analysis was performed on 119 clonal individuals to determine levels of nuclear genetic variation within the clonal line. Twelve primer sets revealed nine polymorphic bands among the 493 readable bands. Seventy individuals showed between one and five polymorphic loci with nuclear AFLP band variation ranging from 0.0% to 1.01% among all possible pairs. DNA from 12 individuals containing variable loci was re-extracted and AFLP amplifications repeated. Repeated primer sets showed little variation between extractions with polymorphic loci present in all repeated primer sets. AFLP primer sets having polymorphic loci were run using OSU by Arlee doubled haploids to determine map locations on the published linkage map of rainbow trout. Three of the nine polymorphic loci had differential polymorphism between the parents to allow mapping. Two loci mapped to linkage group II 46.2 and 32.6 centimorgans away from the putative centromere while the third locus was unassignable. The large distances between the two mapped loci and the putative centromere, along with the inability to assign the third locus, support the possibility that identified variable loci result from tetrasomic inheritance. The type of tetrasomic inheritance present is the result of distal crossover between homologous chromosomes during spermatogenesis, secondary tetrasomy. The low level of genetic variation found within the OSU clonal line is comparable to reported genetic variation within inbred lines of mice, zebrafish, and other species.
Anomalous Grain Boundary Physics in Polycrystalline CuInSe2: The Existence of a Hole Barrier

First-principles modeling of grain boundaries (GB) in CuInSe2 semiconductors reveals that an energetic barrier exists for holes arriving from the grain interior (GI) to the GB. Consequently, the absence of holes inside the GB prevents GB electrons from recombining. At the same time, the GI is purer in polymaterials than in single crystals, since impurities segregated to the GBs. This explains the puzzle of the superiority of polycrystalline CuInSe2 solar cells over their crystalline counterpart. We identify a simple and universal mechanism for the barrier, arising from reduced p-d repulsion due to Cu-vacancy surface reconstruction. This discovery opens up possibilities for the future design of superior polycrystalline devices.
