Temperature Dependence of the Artificial Photosynthesis Reactions Catalyzed by Nanostructured Co/CoO.

Carbon dioxide (CO2) and water (H2O) have been converted into hydrocarbons at temperature ranging from 58 to 242 °C through an artificial photosynthesis reaction catalyzed by nanostructured Co/CoO. The experimental results show that chain hydrocarbons (alkane hydrocarbons) (C n H2n+2, where 3 ≤ n ≤ 16) mainly form at a temperature higher than about 60 °C, the production rate reaches a maximum at 130 °C, and abruptly decreases above 130 °C, and then gradually increases until 220 °C. While the temperature is higher than 220 °C, benzene (C6H6) and its derivatives such as toluene (C7H8), p-xylene (C8H10), and C9H12 form. The modeling of temperature dependence of the reaction rate reveals that the vaporization of the adsorbed water contributes to the sharp peak; the activation energy is estimated as about 1 eV, which is in agreement with the reaction of CO and H2 to synthesize chain hydrocarbons. The experimental results support the mechanism that the chemisorbed CO2 and physisorbed H2O on the CoO surface are disassociated or excited with light, and the disassociated or excited molecules then synthesize hydrocarbons. When most of the water molecules leave from the CoO at temperature higher than 220 °C, the hydrogen source is of very low concentration while the carbon source remain the same because of the chemisorption, and thus benzene and its derivatives with low hydrogen atom number form.
Iron polypyridyl complex adsorbed on carbon surfaces for hydrogen generation

A series of homogeneous Fe(III) complexes were recently reported that are active for electrocatalytic hydrogen generation. Herein we report a naphthalene-terminated Fe(III) complex for use in the functionalization of glassy carbon surfaces for electrocatalytic hydrogen generation with retention of catalytic activity.
Essay: Beyond Nationalism and Toward a Dynamic Theory of Pan-African Unity

For decades, Pan-African unity has provided the conceptual platform upon which theories of global racial justice for the African Diaspora have been grounded. Moreover, by encouraging capital and labor market deregulation globally, thereby accelerating labor competition between African-American and Sub-Saharan African workers, multilateral trade agreements challenge a core premise around which Pan-Africanism operates: that the intersection of shared racial justice interests can form the basis for multi-party global collaboration in the political, legal, and economic spheres." In the same vein, noted critical race globalist Professor Ibrahim Gassama has argued in favor of an informed critical race response to the perceived ills of trade multilateralism. Thus, a domestic call to resist AGOA because it will result in the relocation of African-American jobs over-seas, without also considering the impact such a critique will have on those Sub-Saharan African states party to AGOA fairly misses the forest through the trees. In this sense, AGOA's critics must look beyond domestic economic considerations and embrace a broader and more nuanced ide-ology of Pan-African unity in order to promote and pursue a shared interest in economic security and stability.
Post vaccination morphea in a child

Morphea also termed as localized scleroderma is a rare, chronic skin condition. It is classified into five types. The etiology and pathogenesis is largely unknown but a variety of triggers have been implicated as predisposing factors, including local trauma. There have been a few case reports about the possible association of immunization and subsequent development of morphea. We present a child in whom we believe, the lesions of morphea occurred after routine childhood immunization.
John Rawls’ Difference Principle: Evidence from Guatemala

While literature indicates that strong intellectual property (IP) protection is needed to attract foreign direct investment (FDI) in developing countries like Guatemala, the literature fails to address adequately the economic, social, and political considerations facing developing nations in the reformation of their IP laws. This article addresses those considerations by applying John Rawls’ Difference Principle. Rawls’ Difference Principle depicts justice as an issue of fairness, which focuses on the distribution of resources and permits an unequal distribution only to the extent that the weakest members of society benefit from that inequality. This article finds that Rawls would reject the findings from the literature and support a weak IP regime in Guatemala for three key reasons. First, economically, Guatemala’s weakest members would have immediate access to otherwise price-prohibitive products. Second, socially, Guatemala could reallocate resources to service Guatemala’s weakest members more pressing needs. Third, politically, Guatemala’s IP weak regime would be entirely consistent with the letter of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) and improve relations with its trading partners. According to Rawls, Guatemala’s approach to maintain a weak IP regime would be ethically sound.
Narrative Policy Framework: The Influence of Media Policy Narratives on Public Opinion

Policy narratives are pervasive in the policy arena with interest group letters, speeches, and media reports. The role policy narratives play is becoming increasingly important in policy sciences research. The central question addressed here concerns what effect policy narratives have on public opinion. To measure this, we use a quasi-experimental design with 194 students and a controversial issue in Yellowstone National Park. Respondents took a pretest for baseline opinion data. The treatment was one of two media accounts that reflect divergent advocacy coalitions, followed by a posttest. Results indicate that media policy narratives are influential on public opinion in two ways. First, they “preach to the choir” when read by audiences with similar opinions; the result is a significant strengthening of congruent reader opinions. Second, they “convert” when read by audiences with divergent opinions; the result is a significant strengthening of opinion in the opposite direction of previously held opinions. Las narrativas politicas se encuentran presentes en el ambiente politico con cartas de grupos de cabildeo, discursos y reportes en los medios. El papel de las narrativas politicas esta tomando una mayor importancia en la investigacion de las politicas publicas. El tema central de este articulo es el efecto de las narrativas politicas sobre la opinion publica. Para medir esto usamos un diseno cuasi experimental con 194 estudiantes y un tema controversial en el Parque Nacional de Yellowstone. Los participantes tomaron un test inicial usado como referencia base. La informacion se presento en una de dos condiciones que reflejaban grupos de intereses divergentes, seguida por una segunda encuesta. Los resultados indican que las narrativas politicas de los medios influyen en dos formas. Primero, estas “predican a los convertidos” cuando son leidas por audiencias con opiniones similares, resultando en un reforzamiento significativo de opiniones congruentes. Segundo, estas “ convierten” a lectores con puntos de vista diferentes; el resultado es un cambio de opinion significativo en la direccion opuesta a las opiniones sostenidas previamente.
Challenges and Strategies in Social Work and Social Welfare PhD Education: Helping Candidates Jump through the Dissertation Hoops.

A major task of social work doctoral programs is preparing the next generation of researchers and educators in the profession. To develop competence in generating new knowledge relevant to social work practice and disseminating it to future practitioners, doctoral candidates need to master a broad and complicated set of theoretical, empirical, and pedagogical knowledge and skills. Acquiring the relevant information and capabilities is a demanding process. Specifically, developing a research proposal and completing a successful dissertation is a complex, multifaceted task. In the process of accomplishing this task, students encounter intellectual, logistic, and emotional challenges. The main resource for helping them shoulder these challenges is the advisor. Informed by many years of the author’s service as a dissertation advisor, this article reviews the challenges and offers effective strategies that the advisor can use to help the students address them.
Financial liberalization and the onset of financial crisis in Western European states between 1983 and 2011: An econometric investigation

This paper argues that financial liberalization played a significant role in destabilizing Western European economies since the financial crisis of 2008. This process owes much to changes in the financial governance of Western Europe in the late 20th century. This contrasts with the conventional story that the Eurocrisis is primarily due to peripheral countries’ excessive government spending or the German government's neo-mercantilist policies. The paper shows a robust and statistically significant positive correlation between gross locational capital flows over GDP and the onset of financial crisis, using linear probability models and logit regressions, providing evidence for the hypotheses.
Neural correlates associated with symptom provocation in pediatric obsessive compulsive disorder after a single session of sham-controlled repetitive transcranial magnetic stimulation

Treatments for pediatric obsessive-compulsive disorder (OCD) could be enhanced if the physiological changes engendered by treatment were known. This study examined neural correlates of a provocation task in youth with OCD, before and after sham-controlled repetitive transcranial magnetic stimulation (rTMS). We hypothesized that rTMS to the right dorsolateral prefrontal cortex would inhibit activity in cortico-striato-thalamic (CST) circuits associated with OCD to a greater extent than sham rTMS. After baseline (Time 1) functional magnetic resonance imaging (fMRI) during a provocation task, subjects received one session of either fMRI-guided sham (SG; n=8) or active (AG; n=10) 1-Hz rTMS over the rDLPFC for 30min. During rTMS, subjects were presented with personalized images that evoked OCD-related anxiety. Following stimulation, fMRI and the provocation task were repeated (Time 2). Contrary to our prediction for the provocation task, the AG was associated with no changes in BOLD response from Times 1 to 2. In contrast, the SG had a significant increase at Time 2 in BOLD response in the right inferior frontal gyrus and right putamen, which persisted after adjusting for age, gender, and time to scanner as covariates. This study provides an initial framework for TMS interrogation of the CST circuit in pediatric OCD.

Prevalence of clinical and isolated subclinical cardiovascular disease in older adults with glucose disorders: the Cardiovascular Health Study.

OBJECTIVE—Clinical cardiovascular disease (CVD) is highly prevalent among people with diabetes. However, there is little information regarding the prevalence of subclinical CVD and its relation to clinical CVD in diabetes and in the glucose disorders that precede diabetes. RESEARCH DESIGN AND METHODS—Participants in the Cardiovascular Health Study, aged ≥65 years (n = 5,888), underwent vascular and metabolic testing. Individuals with known disease in the coronary, cerebral, or peripheral circulations were considered to have clinical disease. Those without any clinical disease in whom CVD was detected by ultrasonography, electrocardiography, or ankle arm index in any of the three vascular beds were considered to have isolated subclinical disease. RESULTS—Approximately 30% of the cohort had clinical disease, and ∼60% of the remainder had isolated subclinical disease. In those with normal glucose status, isolated subclinical disease made up most of the total CVD. With increasing glucose severity, the proportion of total CVD that was clinical disease increased; 75% of men and 66% of women with normal fasting glucose status had either clinical or subclinical CVD. Among those with known diabetes, the prevalence was ∼88% (odds ratio [OR] 2.46 for men and 4.22 for women, P CONCLUSIONS—Isolated subclinical CVD is common among older adults. Glucose disorders are associated with an increased prevalence of total CVD and an increased proportion of clinical disease relative to subclinical disease.
Experimental and finite element analyses of a sliding-tube-type driveshaft-induced vehicle vibration

AbstractDriveline noise, vibration, and harshness (NVH) has become an integral attribute in defining how the vehicle NVH performance is perceived by the customers of the automotive industry. The driveshaft component design requirements need to make sure that the designed driveline system is robust and reliable in order to achieve the vehicle NVH targets. They also need to ensure that the system maintains its durability performance as well.A slip mechanism in the driveline system is needed to accommodate the movements caused by the rear axle and rear suspensions when the vehicle travels on a rough road or accelerates/ decelerates abruptly. One design option to accommodate the slip mechanism is to use a press-fitted sliding-tube design. This slip mechanism causes the fluctuation of the contact forces in the tubes, particularly in the vehicle coast down course, and becomes a non-linear contact force phenomenon. This paper uses experimental and finite element method linear tools to explain the non-linear beha...
Macroscopic Conductivity Measurements of Ionized Air

Ionization chamber measurements of bulk ionized air conductivity are complicated by the formation of a diode-like electron depletion layer at the interface of the negatively charged cathode and the ionized gas. Conduction across the electron depletion layer is dominated by ionic conductivity. The production of secondary electrons at the cathode by positive ion bombardment is postulated to explain abnormally large currents across the electron depletion layer at late time in N2 gas. A biased waveguide rf absorption technique has been developed to measure the electron conductivity of ionized gases in the region outside the electron depletion region.
Quantitative studies of amino acid and growth factor requirements of transformed and nontransformed cells in high concentrations of serum or lymph

The growth rate of spontaneously transformed BALB/3T3 cells is proportional to glutamine concentration between 50 and 400 microM, with little or no growth occurring in less than 50 microM glutamine. By contrast, nontransformed BALB/3T3 cells multiply, although slowly, with as little as 20 microM glutamine. Neither cell type depletes the medium of glutamine at the low concentrations. Cystine requirements of both cell types increase with serum concentration, probably due to the binding of half-cystine residues by the serum. Calf serum is a much more potent stimulator of cell multiplication than calf lymph, especially for the nontransformed cells. The rate of cell multiplication can be reduced by lowering the concentration of essential amino acids to the physiologic level found in body fluids, but the growth limitations can be fully compensated by simply raising the serum concentration. Growth factors may act by enhancing the utilization of amino acids, particularly of glutamine which is a required substrate for the first and chief regulatory steps of purine and pyrimidine synthesis. Lymph, which is coextensive with interstitial fluid in vivo, is poor in growth factors for the nontransformed BALB/3T3 cells as well as for recently explanted mouse embryo cells, which raises questions of how normal cell growth is maintained in the body.
Correlative Conjunctions and Events: A Reply to a Reply

Tsohatzidis (2001) attempts to “dispute the central thesis” of Progovac 1999 that correlative both induces a multiple–event interpretation whereas noncorrelative counterparts are ambiguous or vague between single–event and multiple–event readings. As far as I can see, there can be three types of counterexamples to Progovac: (i) noncorrelative constructions necessarily involving multiple–event interpretations (with no independent factor excluding single–event interpretations); (ii) correlative coordination involving single–event interpretations; and (iii) pairs in which noncorrelative coordination permits multiple–event interpretation but the correlative counterparts only have single–event interpretation. The alleged counterexamples offered in Tsohatzidis are only of types (i) and (ii). On closer inspection, it turns out that the alleged type (i) counterexamples are not true counterexamples because they involve an independent factor, and that the alleged type (ii) counterexamples can be analyzed as involving multiple events. Tsohatzidis's attempt to dispute the claim in Progovac thus fails.
Axonal Transport of Proteins in Experimental Neuropathies

Axoplasmic flow of proteins is interrlupted in cats with neuropatlhy induced by acrylamide, but it is niot initerrupted in nzormlal cats and in those with neuropathy induced by tri-orthocresyl phiospliate. The proteins move from lumbosacral motor neurons along the ventral roots and from ganglion cells toward the spinal cord along the dorsal roots at about 1(1/2) millimeters per day.
The lossy waveguide as a problem in perturbation theory

A systematic perturbation theory for lossy waveguides is presented. Two possible small dimensionless parameters are identified and introduced into Maxwell's equations by rescaling pursuant to effecting an expansion of the fields in these parameters. The approximation scheme can be extended to any order of accuracy desired. Although two small parameters are involved in the expansion of the fields in the guide and its walls, the field equations are shown to force the correct ordering of parameters in this expansion. >
Partial suppression of an ochre mutation in Saccharomyces cerevisiae by multicopy plasmids containing a normal yeast tRNAGln gene

Abstract We screened a yeast genomic library for recombinant DNA plasmids that complemented the ultraviolet (u.v.) sensitivity of a strain of Saccharomyces cerevisiae designated rad4-3 that is defective in excision repair of DNA. A multicopy plasmid (pNF4000) with a 9.4 × 103 base-pair yeast DNA insert partially complemented the u.v. sensitivity of rad4-3, but not of two other rad4 allelic mutants (rad4-2 and rad4-4), or of other u.v.-sensitive rad mutants. The yeast insert was analyzed by restriction mapping, DNA-DNA hybridization, DNA-tRNA hybridization and DNA sequencing. This analysis revealed the presence of a normal tRNAGln gene, a yeast sigma element situated 5′ to the transfer RNA gene, a Ty element and a solo delta element. Deletion analysis of pNF4000 showed that the tRNAGln gene is required for partial complementation of the u.v. sensitivity of rad4-3. Furthermore, a multicopy plasmid containing a tRNAGln gene derived from a different region of the yeast genome also partially complemented the u.v. sensitivity of rad4-3. The rad4-3 mutation is suppressed following transformation with a plasmid containing the known ochre suppressor SUP11-o, indicating that it is an ochre mutation. We therefore conclude that when expressed in sufficient quantity, normal tRNAGln (which usually decodes the sense codon CAA) can weakly suppress the nonsense ochre codon UAA, and suggest that this represents an example of wobble occurring at the first rather than at the third position of the codon.
Protected By Your Self-Control The Influence of Partners’ Self-Control on Actors’ Responses to Interpersonal Risk

Self-control allows people to curb destructive behavior and behave more pro-socially in relationships. Thus, individuals generally trust partners with high dispositional self-control more. However, it is not clear whether partner self-control influences individuals’ responses to acutely risky situations, such as when partners are rejecting. A daily diary study of married and cohabiting couples examined whether actors with high self-control partners behave less self-protectively in risky situations. On days partners were highly rejecting, actors were less likely to retaliate against and more likely to value high self-control partners. On days after partners had been rejecting, actors also reported that high self-control partners behaved more responsively. Actors also trusted partners with high self-control more regardless of risk. Taken together, our findings suggest that partners’ greater self-control may help foster more positive interaction cycles in romantic relationships.
The effects of incentives and personality on salesperson's customer orientation

Abstract Numerous strategies for increasing customer orientation of salespeople, including customer satisfaction-based incentives and selective recruiting, have been suggested; however, little is known about their effectiveness. This study replicates and extends findings from two previous studies by testing the effects of customer and sales volume-based compensation and personality characteristics on the customer orientation of salespeople. Customer satisfaction incentives and salespeople's level of empathy were positively related to customer orientation. Sales volume incentives and job tenure were negatively related to customer orientation. Empathy moderated the effect of customer satisfaction and sales volume incentives on customer orientation. A discussion of the findings, managerial implications, and suggestions for future research are all presented.
Combustion of Heavy Distillate Fuel for the LM2500 Gas Turbine

The LM2500 is a Marine and Industrial gas turbine derived from the TF39 engine built for the USAF C5A transport. As such it operates as a core engine without the high bypass fan supercharging effect. The combustor for the LM2500 is an annular combustor developed for use with marine and industrial fuels including natural gas and heavy distillates. This paper relates the development of this combustor including some of the design criteria, the fuel properties and some of the combustor performance results such as exit gas temperature patterns, ignition, pressure loss, and efficiency. The engine combustor operates with a clear smokeless stack utilizing heavy distillate fuels and is free of carbon formation. Fuel properties and atomization properties are related to exhaust smoke. Investigations have included a wide range of fuels and several fuel injector designs. The engine has operated in GTS Adm. Wm. M. Callaghan for a total of more than 10,000 hrs with no combustor problems, smoke, carbon, life or otherwise.Copyright © 1972 by ASME
Müllerian inhibiting substance inhibition of a human endometrial carcinoma cell line xenografted in nude mice.

Abstract Mullerian inhibiting substance (MIS) is a fetal testicular product which causes regression of the mullerian duct in the male mammalian embryo. This material has been partially purified from a neonatal bovine source and in cruder fractions has shown antitumor effects when tested against the HOC-21 ovarian carcinoma line in monolayer cytotoxicity, in soft agar colony inhibition assay, and in nude mouse xenografts. The glycoprotein used for the present studies was more highly purified by sequential ion exchange, carbohydrate affinity, and dye affinity chromatography. After a 1-hr exposure with 1.0 × 10 6 tumor cells prior to heterotransplantation, this more purified preparation with MIS biological activity as determined by organ culture assay of embryonic urogenital ridges delayed the appearance of palpable tumor nodules. That this response may be specific for tumors derived from the coelomic epithelium of the embryo is further supported by the absence of any antitumor effect when this substance was tested against the SW-48 colon carcinoma line. It is of interest that the antitumor activity followed the biological activity as the preparation was further purified to 30,000-fold.
Schizophrenia-like attentional deficits following blockade of prefrontal cortex GABAA receptors.

Attentional deficits are a core symptom of schizophrenia. Post-mortem analyses of the brains of schizophrenics reveal consistent abnormalities in γ-aminobutyric acid (GABA) interneurons indicative of reduced cortical GABA transmission, raising the possibility that this pathology contributes to attentional deficits. We examined whether blockade of prefrontal cortex (PFC) GABAA receptors with bicuculline (BMI) impairs attention in rats using the 5-choice serial reaction time task (5CSRTT). For comparison, we also examined whether administration of the GABAA receptor agonist muscimol (MUS) would improve attention. In parallel, we examined the effects of both manipulations on activity in an open field and on motivation using the intracranial self-stimulation (ICSS) test. BMI increased PFC neuronal activity, as reflected by increased Fos immunolabeling, and impaired attention, as reflected by decreased accuracy and increased omissions. Although increased omissions also may reflect reductions in locomotor activity or motivation, the overall pattern of effects does not support either of these interpretations: BMI did not affect locomotor activity, and it enhanced motivation in the ICSS test. MUS did not affect attention, although it increased impulsive behavior at a dose that suppressed PFC neuronal activity, as reflected by decreased Fos immunolabeling. These impulsivity effects are not due to altered locomotor activity (which was decreased) or motivation (which was not affected). Our data support the hypothesis that cortical GABA neurons have an important role in regulating attention and may have direct implications for the treatment of schizophrenia.
Exact derivation of the tensile strain and strain rate equations for a rotating capstan fiber tester

A rotating capstan fiber tester (RCFT) differs from an Instron-type translating test device primarily in the method of strain. That is, even with a constant capstan rotation rate, an RCFT does not strain fiber at a uniform (constant) rate. In this paper exact relationships for RCFT strain and strain rate are derived. Strain is an exponential function of rotation and strain rate is a function of instantaneous strain. It is shown however that the difference between a rate assumed constant and an exact, strain dependent strain rate is negligible with respect to resulting break strengths. Preliminary comparison testing demonstrates that the mean strength values between instruments are, within measurement variability, different by no more than predicted levels of a fraction of a percent.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.

CTC medium: a novel dodine-free selective medium for isolating entomopathogenic fungi, especially Metarhizium acridum, from soil.

The selective media most commonly used for isolating hyphomycetous species of entomopathogenic fungi from non-sterile substrates rely on N-dodecylguanidine monoacetate (dodine) as the selective fungicide. Although these media are effective for isolating many species of Metarhizium and Beauveria from soil, they are inefficient media for isolation of an important Metarhizium species, Metarhizium acridum, from non-sterile soil. Our current study was directed to formulating a dodine-free selective medium that is efficient for isolating naturally occurring Beauveria spp. and Metarhizium spp., especially M. acridum, from soil. The selective medium (designated CTC medium) consists of potato dextrose agar plus yeast extract (PDAY) supplemented with chloramphenicol, thiabendazole and cycloheximide. In comparisons with selective media previously reported in the literature, the CTC medium afforded colonies that were larger and had both earlier and more abundant conidiation of entomopathogenic fungi, features which greatly facilitated identification of the emerging entomopathogenic fungi. In addition to efficient re-isolation of M. acridum, this medium also is an effective tool for selective isolation of Metarhizium brunneum, Metarhizium robertsii, Beauveria bassiana and Beauveria brongniartii from non-sterile field-collected soil samples inoculated (spiked) with fresh conidia in the laboratory.

Quantitative analysis of exocytosis and endocytosis in the hydroosmotic response of toad bladder

This study concerns the timing and magnitude of exocytosis and endocytosis in the granular cells of toad bladder during the hydroosmotic response to antidiuretic hormone. Granule exocytosis at the luminal cell surface is extensive within 5 min of the administration of a physiological dose of hormone. Hydroosmosis becomes detectable during this time period. The amount of membrane added to the luminal surface by exocytosis during 60 min of exposure to hormone can be of the same order of magnitude as the extent of the luminal plasma membrane. Endocytosis, demonstrated by peroxidase uptake from the luminal surface, becomes extensive during the period 15–45 min after hormone administration. Thus, maximal endocytic activity occurs later than the period of most extensive exocytosis and seems to correlate with the onset of the decline in water movement. The amount of membrane retrieved from the luminal surface by endocytosis during 60 min of stimulation is at least three quarters of that added by exocytosis. The bulk membrane movement in ADH stimulated preparations does not require the presence of an osmotic gradient. Colchicine inhibits the hydroosmotic response, the exocytosis of granules, and endocytosis at the luminal surface. These results strengthen our view that the bulk circulation of membrane at the cell surface, via exocytosis and endocytosis, is closely related to the permeability changes occuring at the surface.
Core business architecture for a service-oriented enterprise

The business architecture of a service-oriented enterprise can be adequately represented through five main architectural domains: business value, structure, behavior, policy, and performance. In this paper we focus on the core business architecture, the set of essential elements in each of the five domains, and the interrelationships among these elements. The business architecture described in this paper identifies the key elements required for business reasoning and for its application to business transformation through service-oriented solutions. A business scenario involving a fictional company in the apparel business illustrates the concepts presented here.
Technology infrastructure in support of a medical & bioinformatics masters degree

Grand Valley State University has recently created a new Masters program in Medical & Bioinformatics. The M.S. degree, along with related degrees in Biostatistics and Biotechnology, are components of the "Professional Science Masters" development and implementation initiative supported by the Sloan Foundation. Key features of the new curriculum include an interdisciplinary framework with common core courses, the promotion and development of "soft skills" through teamwork and project management experiences, and an applied research focus highlighted by a mandatory business/industry internship. Instrumental to achieving these goals is a strong lab component to the curriculum that incorporates familiarity with industry-standard software packages. The laboratory infrastructure will be utilized by multiple courses, thus interconnecting different foci of the program and providing a complete experience for students.
Our lives as surgeons: Finding a sense of place and purpose

I will say that I am astonished to be standing here now. Who would have thought that more than 3 and a half decades ago, when I started my surgical journey, I would be standing here giving a lecture established in tribute to the first woman surgeon anyone ever spoke of to me. The year was 1978. I was a young medical student recently smitten by surgery, at a very southern medical school, my University of Virginia (UVA), which I truly love despite the fact that it was many years, if not decades, before a woman surgery faculty member arrived on campus. I certainly could not find one there and then. I did, however, have a wonderful new-found mentor after my defection from pediatric genetics to surgery, named Dr Les Rudolph. Dr Rudolph, like Dr Jonasson, was a pioneer in the field of transplantation surgery, and was one of few surgical faculty at UVA who, despite my place near the top of the class, had embraced my ambition to pursue surgery these 35 years ago. (I might add that several others have now claimed a mysterious role in my decision.somehow I missed that input at the time!). At one of our meetings, he told me that he thought I should know that womendat least somewhere elsedhad become surgeons and had, in fact, risen to be leaders in my now newly intended future field of practice. He told me in one breath of the 2 he kneweand whom I must meet: Dr Olga Jonasson and Dr Katherine Anderson. I trust both names are familiar to all in this room, but for those who do not know the name of Dr Katherine Anderson, she is a marvelous pioneering leader in pediatric surgery and just 9 years ago, was the first woman to be president of the American College of Surgeons. With Dr Rudolph’s help, I found Dr Anderson, the first woman surgeon I ever met, long before Dr Jonasson, meeting her in my home town of Washington DC, first as a medical student and then as a resident, and she subsequently became a lifelong mentor and friend.
Observational determination of the greenhouse effect

Satellite measurements are used to quantify the atmospheric greenhouse effect, defined here as the infrared radiation energy trapped by atmospheric gases and clouds. The greenhouse effect is found to increase significantly with sea surface temperature. The rate of increase gives compelling evidence for the positive feedback between surface temperature, water vapor and the greenhouse effect; the magnitude of the feedback is consistent with that predicted by climate models. This study demonstrates an effective method for directly monitoring, from space, future changes in the greenhouse effect.
A modified Lempel-Ziv algorithm and its application to image compaction

A modified Lempel-Ziv (1978) algorithm (m-LZA) for data compaction is proposed. The performance of the m-LZA in terms of compaction rate is better than the performance of the LZA. The improvement realized by examining the tree structure underlying the LZA is corroborated by comparing the compaction rates obtained with the application of both algorithms to the compaction of image data. Another interesting feature of the m-LZA is its independence of the size of the source alphabet. >
THE USE OF A DECISION MAKER'S UTILITY FUNCTION IN A LINEAR PROGRAMMING ANALYSIS OF AGRICULTURAL POLICY*

A decision theoretic approach to agricultural policy decision making is examined to discover whether a utility function of an Australian Wool Corporation decision maker can be established and, if so, whether this can be used to improve the policy analysing performance of an agricultural sector linear programming model. After discussing the theoretical requirements of the utility function elicitation and the elicitation procedures, the characteristics of the resulting functions are examined. A means for its inclusion in a linear programming framework is described and some analysis of policy is carried out. The general conclusions are that the relevance of the agricultural sector analysis is enhanced by the use of such a utility function.
From flexibility to constraint: The contrastive use of lexical tone in early word learning

Infants must develop both flexibility and constraint in their interpretation of acceptable word forms. The current experiments examined the development of infants' lexical interpretation of non-native variations in pitch contour. Fourteen-, 17-, and 19-month-olds (Experiments 1 and 2, N = 72) heard labels for two novel objects; labels contained the same syllable produced with distinct pitch contours (Mandarin lexical tones). The youngest infants learned the label–object mappings, but the older groups did not, despite being able to discriminate pitch differences in an object-free task (Experiment 3, N = 14). Results indicate that 14-month-olds remain flexible regarding what sounds make meaningful distinctions between words. By 17–19 months, experience with a nontonal native language constrains infants' interpretation of lexical tone.
Evolution in economic games

Abstract This paper examines the conditions under which evolutionary processes ‘select’ equilibrium strategies of agents or firms. Under plausible dynamics, optimal selection takes place provided that economic agents are small relative to the environment — that is, each such agent has a negligible effect on others' payoffs. However, when this assumption is not met, survival need not imply optimality. Examples in the contexts of bargaining, bidding, and market competition are presented.
Local representations using very short labels

Abstract A local representation of a graph is a data structure which places a short label on each vertex of the graph so that adjacency between vertices can be deduced just from the vertex labels. By short we mean that the label consists of O ( log n) bits where n is the number of vertices in the graph. It is conjectured (Kannan et al., SIAM J. Discrete Math. 5 (1992) 596–603; Muller, Ph.D. Thesis, Georgia Institute of Technology, 1988) that a hereditary family of graphs P has a local representation provided the number of labeled graphs on n vertices in P is bounded by nkn for some fixed k. Here we develop and prove an analogous result using very short labels on the vertices, i.e., labels with o ( log n) bits.
Fluorescence measurements of duplex DNA oligomers under conditions conducive for forming M-DNA (a metal-DNA complex).

M−DNA (a metal complex of DNA with millimolar concentrations of Zn2+, Co2+, or Ni2+ and basic pH) has been proposed to undergo electron transfer over long distances along the helix and has generated interest as a potential building block for nanoelectronics. We show that DNA aggregates form under solvent conditions favorable for M−DNA (millimolar zinc and pH = 8.6) by fluorescence correlation spectroscopy. We have performed steady-state Forster resonance energy transfer (FRET) experiments with DNA oligomers conjugated with 6-carboxyfluorescein and tetramethylrhodamine to the opposite ends of double-stranded DNA (dsDNA) molecules. Enhanced acceptor emission is observed for distances larger than expected for identical DNA molecules with no zinc. To avoid intermolecular FRET, the fluorescently labeled dsDNA is diluted with a 100-fold excess of unlabeled dsDNA. The intramolecular FRET efficiency increases 25-fold for a 30-mer doubly labeled duplex DNA molecule upon addition of millimolar concentrations of zin...
Fixed Target Charm Physics

Here I recount some history of fixed-target charm physics, and describe how such experiments were / are done. Next, I highlight some of the main results from fixed target charm experiments, including in areas of charm mixing, searches for CP violation and for rare decays, studies of semileptonic decays and charm baryons, as well as Dalitz-plot based analyses and studies of charm production.
Small bowel endometriosis masquerading as regional enteritis

A 35-year-old female presented with recurrent right lower quadrant pain, nausea, and vomiting. She was afebrile with diffuse abdominal tenderness. Plain x-ray of abdomen revealed small bowel obstruction. A barium x-ray of the small bowel showed stricture of the terminal ileum. A CT scan of the abdomen showed a 6-cm mass in right lower quadrant. She was empirically managed as having Crohn's disease. She underwent laparotomy after failure of medical management with high-dose steroids. There was ulceration and narrowing of terminal ileum. Frozen sections revealed endometriosis. Ileocecectomy was performed. Histopathology of resected specimen confirmed the diagnosis of endometriosis, and there was no evidence of chronic inflammatory bowel disease or neoplasia. Ileal endometriosis should be considered in the differential diagnosis of Crohn's disease in menstruating females presenting with perimenstrual symptoms.
Identification of recombination luminescence transitions in N-doped GaAs1−xPx (x = 0.87)

Abstract Photoluminescence measurements at 4.2°K on GaAs1−xPx : N (x=0.87) exhibit recombination transitions at isolated nitrogen centers, along with phonon replications. Variation of N concentrations over several orders of magnitude by ion implantation reveals no evidence of nitrogen pair participation. These results contradict previous identification of NN-pair recombination luminescence in GaAs1−xPx ( x⪕0.87 ).
On Coordinate-Free Rotation Decomposition: Euler Angles About Arbitrary Axes

This paper focuses on Euler angles and on the decomposition of rotations. We consider arbitrary rotation axes that are not necessarily mutually orthogonal; we characterize the set of rotation matrices that admit Euler angles about arbitrary rotation axes; and we provide a single set of Euler angle formulas that applies to any selection of rotation axes. The results are presented and derived in a coordinate-free setting, where no reference frames are required, and no components of any array or matrix are manipulated.
Laparoscopic excision of early interstitial pregnancy with combined usage of intra‐abdominal ultrasonography

We report the cases of one patient with a right cornual pregnancy and one with a right interstitial pregnancy who were treated successfully with laparoscopic resection. In the patient with interstitial pregnancy, intra-abdominal ultrasonography was used for definite diagnosis and confirmation of complete removal of gestational tissue during the operation. These two patients were discharged within 2 days and could return to work within 1 week after the procedure. For a well experienced laparoscopist, these dangerous forms of ectopic pregnancies may not be contraindications to be laparoscopic management. For cases with uncertain diagnosis before operation, the combined use of intra-operative ultrasound is efficacious and recommended.
A note on the fine structure of the Ochromonas danica “tail”

The fine structure of the Ochromonas danica “tail” is detailed. The microtubules, microtubule anchoring structures, posterior swelling, surface vesicles, and in some instances cup shape of the tail end are described and used to explain the behavior of the organism when attached to surfaces.
Structural biology: Action at a distance in a light receptor

A tour de force of X-ray scattering has yielded structures of a phytochrome photoreceptor in its dark and illuminated states, showing how localized protein refolding magnifies a light signal to form a cellular message. See Letter p.245 The crystal structure of the photosensory core of a bacterial phytochrome in both the resting and the active (illuminated) state has now been solved. Working with the phytochrome from the extremophile Deinococcus radiodurans, Sebastian Westenhoff and colleagues demonstrate that toggling between resting and active forms is mediated by a conserved 'tongue' that contacts the chromophore. Atomic-scale structural changes in the vicinity of the chromophore are amplified as they are transmitted through the tongue and beyond, culminating in a nanometre-scale conformational signal that feeds into the rest of the cellular signalling network.
Statistics of momentum flux estimation

Abstract The effect of geophysical noise on the precision of momentum flux measurements is examined. The dominant contribution to the uncertainty of momentum flux estimates scales with the geometric mean of the energy in horizontal and vertical wind fluctuations. To obtain statistically significant measurements of the momentum flux, long integration times are necessary since the flux is typically a small fraction of the geometric mean energy. For example, when the fraction is 1%, at least 16 days of stratospheric measurements will be needed for reliable flux estimation.
