PERCOLATION ON GRIGORCHUK GROUPS

Let p c(G) be the critical probability of the site percolation on the Cayley graph of group G. Benjamini and Schramm (Benjamini, I; Schramm, O. Electron. Comm. Probab. 1996, 1, 71–82) conjectured that p c < 1, given the group is infinite and not a finite extension of . The conjecture was proved earlier for groups of polynomial and exponential growth and remains open for groups of intermediate growth. In this note we prove the conjecture for a special class of Grigorchuk groups, which is a special class of groups of intermediate growth. The proof is based on an algebraic construction. No previous knowledge of percolation is assumed.
The changing face of paranasal sinus fungus balls.

Objectives:We describe the clinical, radiographic, and histopathologic characteristics of fungus balls.Methods:We performed a retrospective review of 24 consecutive patients with the diagnosis of a paranasal sinus fungus ball (mycetoma) from 2001 to 2008.Results:We found that 18 of the 24 primarily involved sinuses had bony thickening, and 13 of the 24 had notable dilatation of the ostium. Eleven of the 24 patients were found to have some degree of immunocompromise (from organ transplantation, diabetes, etc). The patient's immune status correlated with the type of fungus involved. (Mucor-like fungi were more common in immunocompetent patients, and aspergillus-like fungi were more common in immunocompromised patients.) Also, there was a predilection for immunocompetent patients to have dilatated ostia, whereas immunocompromised patients were more likely to have a nondilatated ostium (p = 0.019).Conclusions:Our series of paranasal sinus fungus balls defines a group of patients heretofore poorly described in...
Selecting samples for labeling in unbalanced streaming data environments

In this paper we proposed an alternative approach to random selection for labeling extremely unbalanced stream data sets where one class is only 1-10% of the entire data set. Labeling, especially when human resources are needed, is often time consuming and expensive. In an extremely unbalanced data set, usually a lot of data points need to be labeled to get enough minority class samples. The goal of this research was to reduce the total number of samples needed in the labeling process of training new classification models for updating streaming data ensemble classifier. Our proposed approach is to find minority class clusters using the grid density algorithm, and sample minority class instances inside those regions. The result from the synthetic data set showed that efficiency of our proposed approaches varies with different grid sizes. Results on real world data sets confirmed that observation, and showed that when the data set has high dimensionality, dimensionality reduction was useful for reducing the number of grids in the data space increasing sampling efficiency. Our best results showed 19.4% improvement for an eight-dimension data set without dimensionality reduction, and 27.4% improvement for a thirty-six-dimension data set with dimensionality reduction.
Dna fragmentation factor 45 mutant mice exhibit resistance to kainic acid-induced neuronal cell death.

Excitotoxicity is a process where glutamate or other excitatory amino acids induce neuronal cell death. Emerging evidence suggests that apoptosis plays a key part in excitotoxic neurodegeneration. The DNA fragmentation factor 45 (DFF45 or ICAD) is a subunit of a heterodimeric DNase complex crucial for DNA fragmentation during apoptosis. Using a DFF45 mutant mouse model, we previously found that DFF45 deficient cells are more resistant to apoptosis than normal control cells. To investigate whether the lack of DFF45 may attenuate neuronal cell death induced by excitotoxicity, we compared kainic acid-induced seizure behavior and neuronal cell death in DFF45 mutant and wild-type control mice. We found that the mutant mice exhibit similar kainic acid-induced seizure severity compared to control mice. However, DFF45 mutant mice are more resistant than control mice to kainic acid-induced CA3 neuronal cell death. Interestingly, residual DNA degradation can be detected in the hippocampus of DFF45 mutant mice that exhibit KA-induced lesions. Our results suggest that a lack of DFF45 can lead to neuronal resistance to excessive activity-induced toxicity.
The role of instrumental responding and contiguity of stimuli in the development of infant secondary reinforcement

Abstract Ten-month-old infants received contingent pairings of a tone (T+) and food reinforcer. Groups S r and S D received the food on an FI 23-sec schedule for target touching, the former group receiving T+ immediately after the response and 1.5 sec prior to food and the latter group receiving T+ at the end of the intertrial interval. Group SC received food reinforcers 1.5 sec after T+ with no response required. A second tone (T n ) was heard by all groups once during each intertrial interval, at randomly determined points. All groups subsequently were given a spatial discrimination task, receiving T+ for one alternative and T n for the other. Group S r gave significantly more responses for T+ than for T n , but neither of the other two groups produced a superiority for T+. Thus, both contiguity with a primary reinforcer and the presence of an operant during training appear to be necessary for a neutral signal to acquire the ability to enhance responding.
Time lags in a “food–limited” population

We obtained sufficient and necessary and sufficient conditions for the oscillation of all positive solutions of where r, k, τ ∊ (0, ∞) and c ∊ (0,∞). We also obtained sufficient conditions for the global attractivity of the positive equilibrium K.
NMR studies of paramagnetic metal ion interactions with gluconate and 1,5-gluconolactone

Abstract The effect of temperature on the spin-lattice water proton relaxation rates ( R 1p ) of metal ion- gluconate and metal ion-1,5-gluconolactone interactions is determined for hexaaqua Mn(II) and Co(Il) in D 2 O. Activation energies are reported for manganese(II) and cobalt(II) interactions with gluconate and manganese(II) interactions with 1,5- gluconolactone. The plots of 1n R 1p versus T −1 contain an inflection for Mn(II)-gluconate and Co(II)-gluconate complexes in the temperature range 20–36 °C. The results are consistent with the bent chain form of gluconate being the primary structure in solution above 35 °C.
Pain: From Sign to Disease

Pain is a subjective and complex multidimensional sensory experience that usually occurs as a result of tissue trauma. It is generated after extensive neuronal signal processing within the brain following the activation of peripheral high-threshold sensory receptors (nociceptors), which send nerve impulses from the periphery to the central nervous system. Pain resulting from stimulation of nociceptors can be considered a physiological phenomenon as it helps minimizing further tissue damage by activating reflex withdrawal mechanisms and increasing behavioral, autonomical, and neurohumeral responses that are aimed at maintaining body integrity, preventing further tissue injury and promoting healing. However, if persistent, mechanisms described as peripheral and/or central sensitization alter the pain experience in the patient, transforming physiological pain into maladaptive pain, which is dissociated from the original noxious stimuli or healing process. Thus, maladaptive pain must be considered a pathological condition in and of itself. It is often responsible for persistent discomfort and stress of the horse, which can lead to abnormal behaviors, reduced quality of life and, if uncontrolled, distress and eventually humane destruction of the animal. This article intends to give an overview of the anatomic sides as well as physiological and pathophysiological processes involved in the generation, conduction, and integration of nociceptive signals and presents a pain classification scheme that is more indicative of the neural mechanisms underlying pain phenomena and thus provides the veterinarian with a better direction of how to approach pain therapeutically.
The Specificity of Response to Experimental Stress in Patients with Myofascial Pain Dysfunction Syndrome

Comparison of autonomic and muscular response to experimentally induced stress in normal individuals and patients with myofascial pain dysfunction (MPD) syndrome revealed greater masseter and frontalis activity in the patient group, higher gastrocnemius activity in control subjects, and no significant difference in skin conductance and heart rate. This specificity of response to stress supports the psychophysiologic theory of MPD syndrome.
EGFR as a Target: Rationale for Therapy

Objectives To review the biology of the EGFR, its structure, and the associated signal transduction pathways. To provide an overview of the role of EGFR in normal physiology and the pathophysiology of malignancy. Current anti-EGFR treatments are also discussed. Data Sources Research articles. Conclusion EGFR is a valid target in the treatment of solid tumors. EGFR abnormalities and dysfunction are involved in various aspects of carcinogenesis and tumor progression, and EGFR is overexpressed in several tumor types. The development of anti-EGFR therapies represents an important advance in cancer therapy. Implications for Nursing Practice Anti-EGFR therapy is currently available in the clinical setting. Nurses involved in the care of patients with cancer can benefit from an increased understanding of the normal and abnormal function of EGFR in the body and the mechanisms by which anti-EGFR therapies act.
Upregulation of p21WAF1/CIP1 in human breast cancer cell lines MCF-7 and MDA-MB-468 undergoing apoptosis induced by natural product anticancer drugs 10-hydroxycamptothecin and camptothecin through p53-dependent and independent pathways

Recently, natural product DNA topoisomerase I inhibitors 10-hydroxycamptothecin (HCPT) and camptothecin (CPT) have been shown to have therapeutic effects in both in vitro and in vivo models of human breast cancer. In the present study, we characterized the in vitro and in vivo apoptotic pathways induced by HCPT and CPT in the human breast cancer cell lines MCF-7 and MDA-MB-468. Using various DNA fragmentation analyses and the terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay, the apoptosis induced by HCPT and CPT was shown to be dose- and time-dependent. The MDA-MB-468 cells were more sensitive to both HCPT and CPT than MCF-7 cells. HCPT induced apoptosis in MDA-MB-468 cells more effectively than CPT; however, in MCF-7 cells, CPT was more effective than HCPT. The levels of p53 and p21WAF1/CIP1 protein increased in MCF-7 cells treated with HCPT or CPT in a dose- and time-dependent manner. The levels of p21WAF1/CIP1 protein also increased in a dose- and time-dependent manner in MDA-MB-468 cells treated with HCPT or CPT, whereas the mutated p53 protein levels had no significant change. The elevation of p53 protein levels in MCF-7 cells treated with CPT was significantly inhibited by preincubation with DNA breaks inhibitor aphidicolin, while the elevation of p21WAF1/CIP1 protein levels was not inhibited. The elevation of p21WAF1/CIP1 in MDA-MB-468 cells treated with CPT was not inhibited by aphidicolin. Using Northern blot analysis, the transcription of p21WAF1/CIP1 was shown to increase in a dose-dependent manner in MCF-7 and MDA-MB-468 cells treated with HCPT or CPT. These results suggest that treatment with HCPT and CPT results in increased levels of p21WAF1/CIP1 protein and mRNA, and that they induce apoptosis in human breast cancer cells through both p53-dependent and -independent pathways. These findings may be significant in further understanding the mechanisms of actions of camptothecins in the treatment of human cancers.
Temporary Payoffs or Trade Policy Priorities? Congressional Support for Trade Adjustment Assistance

Trade adjustment assistance (“TAA”) programs provide financial benefits and training to workers who have suffered job loss due to foreign competition. Existing research identifies a host of reasons why legislators of different stripes would be willing to support TAA. However, in practice, TAA implementation often does not reflect a broad consensus and is a highly contentious issue. I argue that we can better identify who supports TAA by focusing on the extent to which a legislator will see immediate payoffs from the policy proposal under consideration. Legislators who represent workers vulnerable to trade competition will support such policies to dampen globalization's adverse consequences. Many legislators who prefer greater trade, however, will often not want to bear the budgetary costs of such programs. For this latter group of legislators, even if TAA might potentially have favorable long-term implications—by reducing opposition to trade liberalization, for example—they will only support adjustment assistance when it is paired with other policies that deliver immediate and tangible benefits. A statistical analysis of several recent Congressional votes, as well as a discussion of legislative wrangling during a number of high-profile TAA implementation episodes, yields results consistent with my hypotheses.

Correlation of the Density of the Liquid Phase of Pure n-Alkanes with Temperature and Vapor Pressure

The density of the liquid phase of normal alkanes at the normal boiling point is represented by an empirical equation based on two known variables: the temperature of the normal boiling point and the ratio of the mole weight to the sum of the atomic numbers of all the atoms in the molecule (the “alkane number”). This equation is also valid, when applied to boiling points of different but constant pressures, but with specific coefficients for each pressure. The correlation between these coefficients and vapor pressure leads to one equation for the density of the liquid phase of the first 17 n-alkanes at vapor pressures from 1.333 to 101.325 kPa. Molecular weight and alkane number are also shown to give accurate correlations of the critical density, the liquid density at constant temperature and pressure, and the refractive index at constant temperature and pressure.
Thermal expansion in YbGaGe

Thermal expansion and magnetic susceptibility measurements as a function of temperature are reported for YbGaGe. Despite the fact that this material has been claimed to show zero thermal expansion over a wide temperature range, we observe thermal expansion typical of metals and Pauli paramagnetic behavior, which perhaps indicates strong sample dependence in this system.
Activation of histamine-releasing factor in normal rat plasma by E. coli endotoxin.

SummaryEmploying isolated guinea pig ileum segments in aerated Tyrode solution, 5 to 250 μg aliquots of a physiologically active lipopolysaccharide component of E. coli endotoxin were found capable of activating a potent histamine-like releasing factor upon in vitro incubation with 0.5 ml diluted fresh heparinized normal rat plasma. The release of histamine by this rat plasma factor occurred within seconds after tissue contact. The E. coli endotoxin preparation per se, in the dose-time relations employed, did not liberate histamine directly from the ileum segments; indeed, 2000 μg E. coli endotoxin failed to release detectable histamine during 20 minute tissue contact periods. This lack of histamine-releasing activity could not be attributed to preexisting endotoxin contamination of the tissue bath nor to toxic depression of the histamine sensitivity of the assay system. The above findings, in conjunction with previous evidence, suggest that E. coli lipopolysaccharide behaves, at least in one manner, as d...
Generalized melanosis caused by melanoma of the rectum

Only 29 cases of generalized melanosis caused by melanoma have been described in the English-language literature since the beginning of this century. This is the first reported case in which the primary site of melanoma was the mucosal surface of the rectum and melanosis was a presenting sign of the disease. Generalized melanosis carries a dismal prognosis; none of the reported patients lived beyond 1 year after the onset of pigmentation.
Kidney transplantation from older donors: proceed with caution

Kidney transplantation from living and deceased donors above age 60 increased in recent years in response to organ shortage. With careful screening, short-term follow-up of living elderly donors demonstrated stable remaining kidney function even in those with mild and controlled hypertension. The need for confirmation of long-term safety is heightened by the report by Tan et al. of a high prevalence of nephrosclerotic changes in these donors and evidence for a decreased number of glomeruli in elderly deceased donors.
Asymptotic semismoothness probabilities

We call an integer semismooth with respect to y and z if each of its prime factors is ≤ y, and all but one are ≤ z. Such numbers are useful in various factoring algorithms, including the quadratic sieve. Let G(α,β) be the asymptotic probability that a random integer n is semismooth with respect to n β and n α . We present new recurrence relations for G and related functions. We then give numerical methods for computing G, tables of G, and estimates for the error incurred by this asymptotic approximation.
California's Professional Mentoring Program: how to develop a statewide mentoring program.

Abstract Trends in downsizing, restructuring, increased diversity, and individual responsibility for career development have sparked a renewed interest in mentoring. Technology is changing the way professionals practice, including dieticians. This is reflected in the strategic goals for the American Dietetic Association (ADA). In 1999, with the aid of an ADA Affiliate/Dietetic Practice Group (DPG) Collaborative Strategic Initiatives Grant, a Mid-Career Mentoring Program (MCMP) was developed in California. This program provided an opportunity for dietitians with advanced skills (mentors) to be matched with those desiring to develop new skills (mentees). A six-step process was used to develop the program. The six steps include: appoint a coordinator; identify prospective mentors; locate resources; define tasks and establish procedures; identify mentees; and begin the program. A final product of the grant was the development of the handbook The Helping Hand. This handbook can be used by other affiliates or practice groups that may wish to develop a mentoring program. Mentoring programs can assist registered dietitians and DTRs (dietetic technicians, registered) in developing their educational plans for the new Professional Development 2001 certification process.

Risk factors for injury during adolescence

Injuries kill more American adolescents than all other diseases combined. It is unclear, however, if adolescents are able or willing to provide the information necessary to characterize their risk for injury. Our objective was to determine if adolescents hospitalized for severe injury are more likely than those hospitalized for acute illness to describe risk factors for injury such as: previous injury, family dysfunction, recent stress, or substance use. All patients completed the Offer Self-Image Questionnaire, the Life-Events Scale for Adolescents, the Adolescent Alcohol-Involvement Scale, and the NIDA Adolescent Drug Use Survey. There were no differences between injured and ill adolescents in demographics, impulse control, emotional tone, perceived family function, alcohol scores, or use of cigarettes, marijuana, or other illicit drugs. The groups differed significantly in sex, previous serious injury, previous hospitalization for injury, injury after alcohol or drug use, and life-event scores. The most common life stresses reported were parental or sibling hospitalization, death of a grandparent, school failure or suspension, getting a summer job, and breaking up with a girl/boy friend. Two variables comprised a stepwise logistic regression model designed to differentiate injured from ill adolescents: male sex and life-event score. We conclude that adolescent boys with recent stressful events may be at high risk for unintentional injury.
Long-term survival after lobectomy for non-small cell lung cancer by video-assisted thoracic surgery versus thoracotomy.

Background Video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer (NSCLC) is increasingly popular. However, the oncologic soundness of VATS for patients with NSCLC as measured by long-term survival has not been proven. The objective here is to determine the overall survival (OS) and disease-free survival (DFS) in two well-matched groups of patients with NSCLC resected by VATS or thoracotomy. Methods We conducted a retrospective review of a prospective database to identify patients who had a lobectomy for NSCLC. A propensity score-matched analysis was done with variables of age, sex, smoking history, Charlson comorbidity index, forced expiratory volume in 1 second, lung diffusing capacity for carbon monoxide, histology, and clinical T and N status. Medical records were reviewed and survival was analyzed. Results After matching, there were 208 patients in each group. Patient and tumor characteristics were similar. The VATS group had a shorter length of stay. More nodes (14.3 versus 11.3; p = 0.001) and more nodal stations (3.8 versus 3.1; p p = 0.672). Both the incidence and distribution of recurrence were similar. Multivariate Cox regression analyses of OS and DFS confirmed the noninferiority of VATS. Conclusions For patients with clinical stage I NSCLC, VATS lobectomy offered similar OS and DFS compared with thoracotomy. Thoracotomy offers a more thorough lymph node evaluation, and may be appropriate for patients with more advanced clinical disease.
Advanced Coal-Fired Power Plants

The U.S. Department of Energy is partnering with industry to develop advanced coal-fired electric power plants that are substantially cleaner, more efficient, and less costly than current plants. Low-emission boiler systems (LEBS) and high-performance power systems (HIPPS) are based, respectively, on the direct firing of pulverized coal and the indirectly fired combined cycle. LEBS uses a low-NO x slagging combustion system that has been shown in pilot-scale tests to emit less than 86 g/GJ (0.2 lb/10 6 Btu) of NO x . Additional NO x removal is provided by a moving bed copper oxide flue gas cleanup system, which also removes 97-99 percent of sulfur oxides. Stack levels of NO x can be reduced to below 9 g/GJ (0.02 lb/10 6 Btu). Construction of an 80 MWe LEBS proof-of-concept plant is scheduled to begin in the spring of 1999. Engineering development of two different HIPPS configurations is continuing. Recent tests of a radiant air heater, a key component of HIPPS, have indicated the soundness of the design for air temperatures to 1150°C. LEBS and HIPPS applications include both new power plants and repowering/upgrading existing plants.
A histologic study of replanted and transplanted endodontically and nonendodontically treated teeth in dogs.

Abstract The results of this study indicate that replanted teeth are more acceptable to the host animal than transplanted teeth. The replanted teeth that have been endodontically treated appear to be the most acceptable of the groups studied on the basis of differences observed in bone and cementum resorption. There appears to be little difference between endodontic and nonendodontic replants with respect to ankylosis and bone deposition. Neither ankylosis nor fibrous attachment was observable with any transplanted specimens.
Genetic analysis of frost hardiness traits in tuber-bearing Solanum species

The inheritance of frost hardiness and cold acclimation potential traits was studied in three segregating populations derived from a cross betweenSolanum commersonii Dun. PI 243503 (cmm) andSolanum cardiophyllum Lindl., PI 184762 (cph), two parental genotypes with contrasting frost hardiness and cold acclimation potential. The levels of frost hardiness and cold acclimation potential were expressed as the LT50, the temperature at which 50% of the cells in leaf discs were killed, as measured by the ion leakage method, following a controlled freeze test There was considerable variation in both frost hardiness and cold acclimation potential in all three segregating populations (F1 F1 xcmm, and F1 xcph). Frost hardiness and cold acclimation potential were not correlated, suggesting that these two traits are under independent genetic control. The analysis of generation means indicated that the variation for both traits could be best explained by an additive-dominance model, with additive gene effects the most important Broad-sense heritability was 0.73 and 0.74 in the F1 population, for frost hardiness and cold acclimation potential, respectively, and was 0.85 for either trait in the F1 xcmm population, indicating that these two traits are highly inheritable. Our results suggest that it should be possible to incorporate the frost hardiness and cold acclimation traits from S.commersonii into cultivated potato species.
In Search of a More Reliable Truth: Mourning and Donald Capps’s Psychological Portrait of Jesus

This article is an abridged version of a chapter in my dissertation. In my dissertation, I examine the relationship between personal experience and public theory within certain strands of contemporary psychology of religion and pastoral theology. My guiding theory is Peter Homans’s “mourning religion” thesis. In this chapter, I examine the life and work of Donald Capps, who is the most prolific contemporary writer in the fields of psychology of religion and pastoral theology. I argue that Capps addressed various personal losses in a deeply personal way during his fifties, and I believe that the key moment for Capps in overcoming his melancholia occurred after his application of his melancholia theory to Jesus, because there Capps was able to integrate and to sustain in a satisfying way his various selves and, therefore, open himself up to mourn in a non-defensive way—the way of humor.
Single Layered Small Intestinal Submucosa in the Repair of Severe Chordee and Complicated Hypospadias

ABSTRACTPurpose: Severe ventral chordee often accompanies proximal hypospadias. We describe our experience with single layered small intestinal submucosa (SIS), a commercially available, acellular, collagen based biomaterial, in the repair of severe chordee as part of a multistage approach to the repair of proximal hypospadias.Materials and Methods: Between 2001 and 2002, 9 boys with proximal hypospadias (penoscrotal to perineal) and severe ventral chordee (greater than 40 degrees) underwent SIS grafting to correct the curvature. In each case the urethral plate was transected at the point of maximal curvature, the defect in the corporal bodies was measured, and the SIS graft was cut 2 mm wider around the perimeter of the defect and sutured into place. Skin resurfacing of the ventral penis was performed in standard fashion using Byars flaps. Recurrence of chordee was assessed by an artificial penile erection test at the time of stage 2 reconstruction.Results: Of the 9 boys 8 underwent a planned 2-stage rep...

LAK Cell Mediated Apoptosis of Human Bladder Cancer Cells Involves a pH-Dependent Endonuclease System in the Cancer Cell: Possible Mechanism of BCG Therapy

AbstractIntravesical bacillus Calmette-Guerin (BCG) is an effective treatment for superficial bladder cancer. However, its mechanism has been only partially elucidated. We studied whether LAK cell killing of human bladder cancer cells occurs via apoptosis (programmed cell death) or necrosis.Fluorescent dye labeled T24 cells were observed to undergo morphologic changes associated with apoptosis in the presence of LAK cells when analyzed under a fluorescence microscope. Furthermore, analysis of the DNA isolated from the cytotoxic assay confirmed that the LAK cell induced death of the T24 cells occurred via apoptosis. By pretreating the LAK cells with antifibronectin antibodies, we were able to significantly inhibit the LAK cell killing of the T24 cells. The percentage of cytotoxicity was reduced from 50 percent to 13 percent (p = 0.001), and the apoptotic pattern seen on agarose gel electrophoresis was significantly diminished. There was no significant change in the viability of the LAK cells following trea...
Evaluation of gradient inhomogeneity in the optimal design of gradient coils

The image distortion caused by gradient inhomogeneity was derived from the image equation of Fourier MR imaging. A measurement of gradient inhomogeneity was proposed based on the amount of image distortion. Using the proposed measurement of gradient inhomogeneity in the optimal design of a z-gradient coil reduced image distortion by 39-45% compared to a previously used figure of merit in gradient coil design.
A new method for quality monitoring of induction motors

Catalog data of three-phase induction motors specify values of some operational parameters in addition to the nameplate information. These parameters include the efficiency, power factor, starting current, maximum torque, rated torque, and starting torque. At the end of the manufacturing process, extensive testing is required to ensure that a specific motor meets the specifications. In this paper, a method is presented to ensure that the motor meets the operational parameter specifications, including the tolerances that might be imposed using the results only of the no-load test and the blocked-rotor test. >
Histologic Assessment and Prognostic Factors of Malignant Pleural Mesothelioma Treated With Extrapleural Pneumonectomy

We studied 56 cases of malignant pleural mesothelioma (MPM) treated with extrapleural pneumonectomy (EPP). The slides from the EPP specimens were reviewed, and tumors were classified with the guidance of the World Health Organization classification of pleural tumors. Agreement between the histologic type from the EPP review and the diagnostic procedure (DP) reports was evaluated. Histologic and clinical parameters were also correlated with clinical outcome. There was a significant disagreement (P = .0001) between the histologic type in the DP reports and the EPP specimen review. The histologic type from the DP was associated with disease-specific survival (DSS); however, the histologic type from the EPP specimen was not associated with survival. Postoperative treatment was associated with DSS and with recurrence-free survival. Our study confirms that in many cases, final histopathologic typing of MPM is influenced by complete surgical resection and that initial biopsy should be carefully weighed in the treatment stratification. Malignant pleural mesothelioma (MPM) is the most common malignant tumor of the pleura and the one that poses more difficulty in diagnosis. Its incidence has slightly increased from 0.6/100,000 (1975) to 1.0/100,000 (2002). 1 Mesothelioma is a lethal tumor that has a relative 5-year survival rate of 6.8%. The 2-year survival is 15.3%, and females have been associated with a better prognosis (2- and 5-year relative survival rates of 19.2% and 14.3%, respectively) than males (2- and 5-year relative survival rates of 14.4% and 4.7%, respectively). 1 Age, sex, histologic type, asbestos exposure, and clinical parameters have been associated with different outcomes; however, results have been controversial. 2-19 Three main histologic types of mesothelioma—epithelioid, sarcomatoid, and biphasic—have been universally accepted and included in the World Health Organization (WHO) classification of pleural tumors, 20 as distinct differences in survival have been observed. 2-19 However, mesotheliomas are usually histologically heterogeneous tumors, so that different patterns in different proportions can be observed in a given tumor within a type (eg, all epithelioid) or between types (eg, mixed epithelioid and sarcomatoid). Therefore, the diagnosis and histologic typing of mesothelioma are usually influenced by the size of the tissue sample available for review. 15,21,22
Slug Tests in the Presence of Background Head Trends

We extend Bouwer and Rice (1976) slug test theory to incorporate background head trends that may be important in incompressible material of low permeability k. The extension, which features a convolution integral of the background head, is closed form for linear trends. A sensitivity study suggests that a rising background head can diminish the head changes associated with a slug-out test and underestimate k if it is ignored, as does falling background trend with a slug-in test. A falling background head can reinforce slug-in test head change and, if ignored, can overestimate k, as does a rising background head with a slug-out test. The simple extension is verified by field tests in glacial till and stratified drift deposits in eastern Massachusetts.
Petrology of Fredonia Oölite in Southern Illinois

A tentative history of events for the Fredonia oolite in Illinois, including the "McClosky lime" of the oil fields, is based on examination of thin sections of nineteen specimens from wells and outcrops. Two ages of cementation and two periods of solution are described. Both primary and secondary porosity occur, although the former is more common. Twinning and undulose extinction in coarsely crystalline calcite, penetration of oolites, and disruption of oolites are evidence of pressure related to compaction, and perhaps also to diastrophism.
Transmission scheduling scheme for multirate multicode CDMA networks

A simple packet transmission scheduling scheme is proposed for a multicode CDMA network. The scheme optimizes the channel capacity and tries to meet the multirate transmission demands of all the users by utilizing information about the arrival rates of the users and the characteristic of the CDMA channel. Results show that the proposed scheduling scheme can efficiently allocate channel resource to different users so that the system throughput is maximized and the number of backlogged packets is minimized.
Fuzzy Multi-Dimensional Search in the Wayfinder File System

With the explosion in the amount of semi-structured data users access and store, there is a need for complex search tools to retrieve often very heterogeneous data in a simple and efficient way. Existing tools usually index text content, allowing for some IR-style ranking on the textual part of the query, but only consider structure (e.g., file directory) and metadata (e.g., date, file type) as filtering conditions. We propose a novel multidimensional querying approach to semi-structured data searches in personal information systems by allowing users to provide fuzzy structure and metadata conditions in addition to traditional keyword conditions. The provided query interface is more comprehensive than content-only searches as it considers three query dimensions (content, structure, metadata) in the search. We have implemented our proposed approach in the Wayfinder file system. In this demo, we will use this implementation to both present an overview of the unified scoring framework underlying the fuzzy multi-dimensional querying approach and demonstrate its potential in improving search results.
Logic, Mathematics, and the A Priori, Part II: Core Logic as Analytic, and as the Basis for Natural Logicism

This is Part II of a two-part study of the foundations of mathematics through the lenses of (i) apriority and analyticity, and (ii) the resources supplied by Core Logic. [In Part I we explained what is meant by apriority, as the notion applies to knowledge and possibly also to truths in general. We distinguished grounds for
PTSD SYMPTOMS ACROSS PREGNANCY AND EARLY POSTPARTUM AMONG WOMEN WITH LIFETIME PTSD DIAGNOSIS.

BACKGROUND: Little is known about trajectories of PTSD symptoms across the peripartum period in women with trauma histories, specifically those who met lifetime PTSD diagnoses prior to pregnancy. The present study seeks to identify factors that influence PTSD symptom load across pregnancy and early postpartum, and study its impact on postpartum adaptation. METHOD: The current study is a secondary analysis on pregnant women with a Lifetime PTSD diagnosis (N = 319) derived from a larger community sample who were interviewed twice across pregnancy (28 and 35 weeks) and again at 6 weeks postpartum, assessing socioeconomic risks, mental health, past and ongoing trauma exposure, and adaptation to postpartum. RESULTS: Using trajectory analysis, first we examined the natural course of PTSD symptoms based on patterns across peripartum, and found four distinct trajectory groups. Second, we explored factors (demographic, historical, and gestational) that shape the PTSD symptom trajectories, and examined the impact of trajectory membership on maternal postpartum adaptation. We found that child abuse history, demographic risk, and lifetime PTSD symptom count increased pregnancy-onset PTSD risk, whereas gestational PTSD symptom trajectory was best predicted by interim trauma and labor anxiety. Women with the greatest PTSD symptom rise during pregnancy were most likely to suffer postpartum depression and reported greatest bonding impairment with their infants at 6 weeks postpartum. CONCLUSIONS: Screening for modifiable risks (interpersonal trauma exposure and labor anxiety) and /or PTSD symptom load during pregnancy appears critical to promote maternal wellbeing. Language: en
Winding schemes for wide constant power range of double stator transverse flux machine

Different ring winding schemes for double sided transverse flux machines are investigated in this paper for wide speed operation. The windings under investigation are based on two inverters used in parallel. At higher power applications this arrangement improves the drive efficiency. The new winding structure through manipulation of the end connection splits individual sets into two and connects the partitioned turns from individual stator sets in series. This configuration offers the flexibility of torque profiling and a greater flux weakening region. At low speeds and low torque only one winding set is capable of providing the required torque thus providing greater fault tolerance. At higher speeds one set is dedicated to torque production and the other for flux control. The proposed method improves the machine efficiency and allows better flux weakening which is desirable for traction applications.
Practice patterns and complication rates of thrombolysis for pulmonary embolism

Practice patterns, bleeding complication rates, and outcomes of thrombolytic use for pulmonary embolism (PE) outside of clinical trials are not well characterized. Retrospective cohort study of patients with PE, using an enhanced administrative database of approximately 20 % of hospitalizations in the United States, 2008-2011. We used hierarchical logistic regression to identify patient- and hospital-level factors associated with thrombolytic use and quantified between-hospital variation in thrombolysis. We calculated rates of hemorrhagic complications and mortality in patients receiving thrombolytics stratified by vasopressor use. We identified 91,860 hospitalizations for PE; thrombolytics were utilized in 13.2 % (578/4363) who received vasopressors and 1.6 % (1320/82,997) who did not receive vasopressors. Patients who received thrombolytics were younger, more likely white, with private insurance, fewer comorbidities and more acute organ failures. Hospitals varied widely in thrombolysis rates for PE (0-100 % of patients on vasopressors, 0-12.5 % not on vasopressors) with 17 % of variation unexplained by patient or hospital characteristics. Bleeding complication rates for patients receiving thrombolytics versus no thrombolytics, respectively, were: ICH (0.8 vs. 0.08 %, p < 0.01), major bleeding (13 vs. 3 %, p < 0.01), and major bleeding with transfusion (2.5 vs. 0.05 %, p < 0.01). Among patients given vasopressors, thrombolytics were not associated with hospital mortality (thrombolysis 41 % vs. no thrombolysis 35 % mortality; adjusted OR 0.97, 95 % CI 0.93-1.01, p = 0.15). There is wide variation in thrombolytic use for PE in the US. Patient characteristics and complications associated with real-world thrombolytic use were similar to published randomized trials.

Kirschenmann’s Cultivating an Ecological Conscience: A Better Philosophy for the Food Movement

First paragraph: National Public Radio’s “Morning Edition” program was brought to me this morning by “Monsanto: helping farmers around the world be more sustainable.” From multinational corporations like Monsanto to the vegetable farmer at my farmers’ market, everyone in the agriculture field wants to talk about sustainability. What does sustainable mean? Do humans influence the environment, or are humans and the environment constantly influencing each other? When farmers say they “know” how to farm, what kind of knowledge is that? Is that knowledge drawn from years of experience, or from scientific experiment?...
Effect of graded levels of lactogenic hormone upon mammary gland growth and lactation in rats.

SummaryLactogenic hormone was administered subcutaneously at 1, 2 or 3 mg to lactating rats each day during days 7 to 19. Milk yields were obtained after a 10-hour isolation period of dam from pups on days 14, 16, 18 and 20 of lactation. One mg of lactogenic hormone significantly increased yield on days 18 and 20; 2 mg on days 16, 18 and 20; and 3 mg on days 14, 16, 18 and 20. Maximum stimulation occurred on day 20 with 2 mg and 3 mg of hormone, with 88 and 82% increase over controls, respectively. Determination of deoxyribo- and ribo-nucleic acids of mammary glands from lac-tators sacrificed on day 20 revealed no significant increase in DNA but significant increases in RNA after hormone treatment. The data strongly suggest that maximal levels of litter weight size and mammary gland size are limiting in ability to estimate milk secretion potential, while milk yields and RNA values reflect secretory status beyond these limits. Lactogenic hormone at 2 or 3 mg per day stimulates increased lactation more than...
Nucleate Boiling of Dielectric Liquids on Hydrophobic Patterned Surfaces

This study experimentally investigated the effect of hydrophobic patterned surfaces in nucleate boiling heat transfer. A dielectric liquid, HFE-7100, was used as the working fluid in the saturated boiling tests. Dielectric liquids are known to have highly-wetting characteristics. They tend to fill surface cavities that would normally trap vapor/gas, and serve as active nucleation sites during boiling. With the lack of these vapor filled cavities, boiling of a dielectric liquid leads to high incipience superheats and accompanying temperature overshoots. Heater samples in this study were prepared by applying a thin Teflon (AF400, Dupont) coating on 1-cm2 smooth copper surfaces following common photolithography techniques. Matching size thick film resistors, attached onto the copper samples, generated heat and simulated high heat flux electronic devices. Tests investigated the heater samples featuring circular pattern sizes between 40–100 μm, and corresponding pitch sizes between 80–200 μm. Additionally, a plain, smooth copper surface was tested to obtain reference data. Based on data, hydrophobic patterned surfaces effectively eliminated the temperature overshoot at boiling incipience, and considerably improved nucleate boiling performance in terms of heat transfer coefficient and critical heat flux over the reference surface. Hydrophobic patterned surfaces therefore demonstrated a practical surface modification method for heat transfer enhancement in immersion cooling applications.Copyright © 2014 by ASME
Analysis of serological surveillance results of brucellosis in 2124 human blood specimens in Pingdingshan

Objective To understand the morbidity situation and epidemic law of brucellosis in Pingdingshan city,so as to provide scientific basis for control and prevention of brucellosis. Methods In 9 counties( cities,districts) of Pingdingshan city, serum samples were collected from occupationally exposed population for preliminary screening by RBPT,and the positive samples were then identified by SAT. The test results were judged in accordance with"Diagnostic standard for brucellosis"( WS269-2007). Results A total of 2124 people were involved in brucellosis detection in Pingdingshan,the positive rate of RBPT was 2. 45%,and the positive rate of SAT was 2. 07%,the positive accordance rate of the two was 84. 62%. The positive rate of brucellosis was 3. 20% in 2011,while that was 0. 94% in 2012,the differences had statistical significanve( P 0. 001). There were significant statistical differences in the positive rates of different genders,nations,careers,as well as between urban area and rural area( P 0. 05). But there was no significant statistical difference in the positive rates of different ages( P 0. 05). Conclusion In order to reduce the incidence of brucellosis,it is important to strengthen the management of livestock husbandry and improve the awareness of disease prevention in occupationally exposed population.

ACL Injury Epidemiology

Anterior cruciate ligament (ACL) tear is a relatively common injury with serious short- and long-term repercussions. A number of risk factors, such as female gender or the specific types of sports played, predispose some individuals to ACL injury. There are risk factors that are modifiable, so we can help mitigate this risk through injury prevention training. Interestingly, the rate of ACL tears seems very stable across countries, as are the high rates of additional injuries that occur in conjunction with ACL tears. In this chapter, we will review the data concerning the rates of ACL injury and ACL surgery as well as the risk factors for having an ACL tear.
Selective Gas-Phase Oxidation and Localization of Alkylated Cysteine Residues in Polypeptide Ions via Ion/Ion Chemistry.

The thiol group in cysteine residues is susceptible to several post-translational modifications (PTMs), including prenylation, nitrosylation, palmitoylation, and the formation of disulfide bonds. Additionally, cysteine residues involved in disulfide bonds are commonly reduced and alkylated prior to mass spectrometric analysis. Several of these cysteine modifications, specifically S-alkyl modifications, are susceptible to gas-phase oxidation via selective ion/ion reactions with periodate anions. Multiply protonated peptides containing modified cysteine residues undergo complex formation upon ion/ion reaction with periodate anions. Activation of the ion/ion complexes results in oxygen transfer from the reagent to the modified sulfur residue to create a sulfoxide functionality. Further activation of the sulfoxide derivative yields abundant losses of the modification with the oxidized sulfur as a sulfenic acid (namely, XSOH) to generate a dehydroalanine residue. This loss immediately indicates the presence of...
