    Full Text Available Este artículo analiza los elementos de la metacrítica de la Ilustración de Hamann que permiten remontar a su filosofía el nacimiento de la forma contemporánea que presenta la cuestión del nihilismo, patentes esencialmente en el tratamiento que realiza de la imagen de los falsos silenos o silenos invertidos (máscaras de falsa apariencia brillante para denunciar como irracionalidad el dogmatismo de cierta concepción absoluta de la razón conducente a una falsa filosofía.

  4. Can matter and spirit be mediated through language? Some insights from Johann Georg Hamann

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available The Enlightenment introduced to European philosophy and thought-patterns the strict dichotomy between res extensa and res cogitans; that is, matter and spirit. How to overcome the dichotomy and conceive of the interactions between these planes of reality has since become an overarching issue for philosophers. The theory of evolution, as founded by Charles Darwin, understands human beings, with their ability to think, to have arisen in the evolutionary process. Neuroscience utilises insights from the theory of complex systems to attempt to understand how perception, thought and self-awareness can arise as a consequence of the complex system that is the brain. However, already at the height of the Enlightenment, a contemporary and critic of Immanuel Kant, Johann Georg Hamann, suggested a metaphor for understanding the interrelationship of matter and thought. This metaphor is language. The appropriateness of this metaphor can be seen both in the importance that language abilities play in the evolutionary transition to the human species and in the characteristics of complex adaptive systems.

  7. Dental signs attributed to congenital syphilis and its treatments in the Hamann-Todd Skeletal Collection

    Full Text Available Syphilis in the United States during the 1800s and 1900s had a high prevalence rate causing great concern to health officials. Various measures were taken to control its spread. Mercuric treatments were used up until the introduction of penicillin. The aim of this paper is to determine whether dental abnormalities related to congenital syphilis in individuals who died of syphilis or syphilis-related causes, in the Hamman Todd Osteological Collection, occur and whether mercurial treatment was effective. Hutchinson, Moon and Fournier’s works were analyzed to determine dental abnormalities associated with congenital syphilis and its treatments and used as criteria. Hillson et al. (AJPA,107:25-40 standardized method of description of dental changes was used. In the Hamman Todd Osteological Collection in Cleveland, Ohio, 102 individuals had cause of death recorded in the catalogue as syphilis or lues, and 69 had causes of death relating to syphilis which included paresis (53, aortic insufficiency (15 and pericarditis (1. Thus altogether 171 individuals were studied. Dentition was examined to determine if dental abnormalities associated with congenital syphilis and its treatments were present in individuals not recorded as having congenital syphilis. Crania were examined for any osteological changes. One individual (2266 demonstrated dental malformations possibly related to the congenital disease itself, while three demonstrated dental abnormalities associated with mercuric treatments in childhood (2118, 2263 and 3097. No remarkable bone pathologies were evident on any skull. The use of pre-penicillin treatment of congenital syphilis may have been effective to maintain health into adulthood but not always in eradicating the infection. Effects of mercury on enamel formation and bone changes, need to be considered when making a differential diagnosis of syphilis/congenital syphilis.

  14. Presence detection under optimum fusion in an ultrasonic sensor system.

    2012-04-01

    Reliable presence detection is a requirement in energy-efficient occupancy-adaptive indoor lighting systems. A system of multiple ultrasonic sensors is considered for presence detection, and the performance gain from optimum fusion is studied. Two cases are considered wherein an individual sensor determines presence based on (i) local detection by processing echoes at its receiver, and (ii) the optimum Chair-Varshney fusion rule using multiple sensor detection results. The performance gains of using optimum fusion over local detection are characterized under different sensor system configurations and it is shown that improved detection sensitivity is obtained over a larger detection coverage region.

  1. Cascade of kinetic energy and scalar variance in DC electrokinetic turbulence

    Science.gov (United States)

    Zhao, Wei; Wang, Guiren

    2017-11-01

    Turbulent flow can be generated by DC electrokinetic (EK) force based on the electric conductivity and permittivity variations in fluids, as have been demonstrated by Varshney et al (2016), where a -1.4 slope of velocity power spectrum is observed. Here, we theoretically found the scaling exponents of velocity and scalar structures in the electric-body-force (EBF) dominant subregion of DC EK turbulence were 2/5 (equivalent to the -7/5 slope of velocity power spectrum) and 4/5 respectively. The theory perfectly explains the experimental results of Varshney et al. (2016). Based on Kármán-Howarth equation with forcing terms, the energy cascade process of DC EK turbulence was also investigated. Depending on the electric Rayleigh number (Rae) , two different energy cascade processes may happen. When Rae is small, the kinetic energy cascades along inertial subregion and EBF dominant subregion in sequence, before it is dissipated by fluid viscosity. When Rae is sufficiently large, the inertial subregion may be absent with EBF dominant subregion left. This investigation is very important on understand EK turbulence, which could be widely existed in nature and applied in engineerings. The work was supported by NSFC (11672229), and NSF (CAREER CBET-0954977 and MRI CBET-1040227).

    We have carried out a density functional study of vibrationally inelastic tunneling in the scanning tunneling microscope of acetylene on copper. Our approach is based on a many-body generalization of the Tersoff-Hamann theory. We explain why only the carbon-hydrogen stretch modes are observed in terms of inelastic and elastic contributions to the tunneling conductance. The inelastic tunneling is found to be efficient and highly localized in space without any resonant interaction and to be governed by a vibration-induced change in tunneling amplitude.

    We present first-principles simulations for inelastic electron tunneling spectra of molecules adsorbed on metal surface as measured in scanning tunneling microscopy experiments. Both elastic and inelastic tunneling processes are modeled in terms of Tersoff-Hamann approximation with a full vibration analysis at density functional theory levels. The calculated spectra of carbon oxide and acetylene molecules adsorbed on Cu(100) surface have well reproduced their experimental counterparts. The inelastic electron tunneling images of the observable vibration modes have been provided. The performance of gradient-corrected density functional is compared with that of local density functional.

    -vacancy dislocation loops in the FeO moiré structure. The experimental STM results are compared with the results of electronic structure calculations within the DFT+U scheme for a realistic (sqrt(91)xsqrt(91)R5.2 moiré unit cell supported on Pt(111) as well as with the results from previous studies. We find that one...... type of STM imaging mode, showing both Fe and O atoms, agrees well with simulated STM images, indicating that the simple Tersoff-Hamann theory is partially valid for this imaging mode. In addition, we identify other distinct, element-specific imaging modes which reveal a strong dependence...

    Comprehending violence among bioarchaeological and historical groups is a topic of recent interest among biological anthropologists. This research examines trauma among African American and Euro-American males of low socioeconomic status born between 1825 and 1877. A total of 651 male skeletons from the Cobb, Terry, and Hamann-Todd anatomical collections were macroscopically evaluated for skeletal trauma, based on the presence of fractures and weapon-related wounds, and statistically analyzed according to ancestry, birth (Antebellum, Civil War, Reconstruction), combined ancestry - birth, and collection cohorts. Results indicated that African Americans and Euro-Americans expressed ethnic differences in regard to interpersonal violence. To interpret these disparities, documentary data were used to reconstruct the socioeconomic and cultural environment of these individuals. This research emphasizes the importance of evaluating skeletal data within the context of class, culture, and environment so that behavioral patterns observed in the skeleton can be better understood.

  15. First-principles description of atomic gold chains on Ge(001)

    López-Moreno, S.

    2010-01-25

    We have performed density-functional theory calculations, including the spin-orbit correction, to investigate atomic gold chains on Ge(001). A set of 26 possible configurations of the Au/Ge(001) system with c(4×2) and c(8×2) symmetries is studied. Our data show that the c(4×2) order results in the lowest energy, which is not in direct agreement with recent experiments. Using total-energy calculations, we are able to explain these differences. We address the electronic band structure and apply the Tersoff-Hamann approach to correlate our data to scanning-tunneling microscopy (STM). We obtain two highly competitive structures of the atomic Au chains for which we report simulated STM images in order to clarify the composition of the experimental Au/Ge(001) surface.

    Graphical abstract: - Abstract: Spin-polarized first-principles total energy calculations have been performed to study the structural, electronic and magnetic properties of Mn{sub 3}N{sub 2}(0 0 1) surfaces. It is found that three surface terminations are energetically stable, in agreement with previous scanning tunneling microscopy experiments that have found three different electronic contrasts in their images. It is also found that in all three cases, the topmost layer has a MnN stoichiometry. Density of states calculations show a metallic behavior for all the stable structures with the most important contribution close to the Fermi level coming from the Mn-d orbitals. Our Tersoff–Hamann scanning tunneling microscopy simulations are in good agreement with previous experimental results.

  1. Scaling of velocity and scalar structure functions in ac electrokinetic turbulence

    Zhao, Wei; Wang, Guiren

    2017-02-01

    Electrokinetic (EK) turbulence or electrohydrodynamic (EHD) turbulence has been recently achieved in different fluids under both ac [G. Wang et al., Lab Chip 14, 1452 (2014), 10.1039/C3LC51403J; Phys. Rev. E 93, 013106 (2016), 10.1103/PhysRevE.93.013106] and dc electric fields [A. Varshney et al., Soft Matter 12, 1759 (2016), 10.1039/C5SM02316E]. Here, through dimensional analysis, scaling laws of both velocity and electric conductivity structure functions in the forced cascade region of ac EK turbulence can be predicated (similar to Bolgiano-Obukhov scaling law in turbulent Rayleigh-Bénard convection), in either macroscale or microscale flows. In the forced cascade region, EK force, which relies on the direct cascade of conductivity structures, injects energy directly into a wide spectral region to sustain the flow disturbance. The scaling exponents of the second-order velocity and conductivity structures are 2/5 and 4/5, respectively. In addition to the scaling regions, two characteristic small length scales are derived for both weak and strong electric body forces, respectively. This theoretical investigation can significantly enhance our understanding of EK or EHD turbulence while forced by an ac electric field. It can further broaden our understanding of the forced cascade region of forced turbulence and make the manipulation of the turbulent cascade process more flexible and controllable.

  2. Chance constrained compromise mixed allocation in multivariate stratified sampling

    2016-03-01

    Full Text Available Consider a multivariate stratified population with  strata and  characteristics. Let the estimation of the population means be of interest. In such cases the traditional individual optimum allocations may differ widely from characteristic to characteristic and there will be no obvious compromise between them unless they are highly correlated. As a result there does not exist a single set of allocations  that can be practically implemented on all characteristics. Assuming the characteristics independent many authors worked out allocations based on different compromise criterion such allocations are called compromise allocation. These allocations are optimum for all characteristics in some sense. Ahsan et al. (2005 introduced the concept of ‘Mixed allocation’ in univariate stratified sampling. Later on Varshney et al. (2011 extended it for multivariate case and called it a ‘Compromise Mixed Allocation’. Ahsan et al. (2013 worked on mixed allocation in stratified sampling by using the ‘Chance Constrained Programming Technique’, that allows the cost constraint to be violated by a specified small probability. This paper presents a more realistic approach to the compromise mixed allocation by formulating the problem as a Chance Constrained Nonlinear Programming Problem in which the per unit measurement costs in various strata are random variables. The application of this approach is exhibited through a numerical example assuming normal distributions of the random parameters.

  3. Secure cooperative spectrum sensing for the cognitive radio network using nonuniform reliability.

    Usman, Muhammad; Koo, Insoo

    2014-01-01

    Both reliable detection of the primary signal in a noisy and fading environment and nullifying the effect of unauthorized users are important tasks in cognitive radio networks. To address these issues, we consider a cooperative spectrum sensing approach where each user is assigned nonuniform reliability based on the sensing performance. Users with poor channel or faulty sensor are assigned low reliability. The nonuniform reliabilities serve as identification tags and are used to isolate users with malicious behavior. We consider a link layer attack similar to the Byzantine attack, which falsifies the spectrum sensing data. Three different strategies are presented in this paper to ignore unreliable and malicious users in the network. Considering only reliable users for global decision improves sensing time and decreases collisions in the control channel. The fusion center uses the degree of reliability as a weighting factor to determine the global decision in scheme I. Schemes II and III consider the unreliability of users, which makes the computations even simpler. The proposed schemes reduce the number of sensing reports and increase the inference accuracy. The advantages of our proposed schemes over conventional cooperative spectrum sensing and the Chair-Varshney optimum rule are demonstrated through simulations.

    Cervical facet arthrosis has been implicated as a cause for neck pain, radiculopathy, occipital headache, and ear pain. The objective of this study was to examine the occurrence of facet arthrosis in the cervical spine. This study examined cadaveric specimens from the Hamann Todd Collection. None. None. Four hundred sixty-five skeletally mature human cervical spines from the Hamann Todd Collection in the Cleveland Museum of Natural History were obtained for analysis. We analyzed the facets for arthrosis. We graded no arthrosis as Grade 0. Facets with peripheral osteophytic reaction, but with no lateral mass distortion were graded as Grade 1. Facets with peripheral osteophytic reaction and lateral mass distortion were graded as Grade 2. Facets that were ankylosed were graded as Grade 3. Each specimen was examined bilaterally at levels from C2-C3 through C6-C7, yielding 4,650 specimen assessments. The data were analyzed to compare cervical levels, gender, facet side, age groups, and race. Proportion analysis, using the Fisher exact test, was used to assess for statistical difference between various groupings. In the entire population of 465 specimens, the upper cervical specimens appeared to be affected by facet arthrosis more frequently than the lower levels; 12.37% of the specimens had bony evidence of arthrosis at the C2-C3 level; 13.33% of the specimens had arthrosis occur at the C3-C4 level; 14.62% at the C4-C5 level; 7.85% at the C5-C6 level, and 4.84% at the C6-C7 level. The large majority of all cervical facet arthrosis was found to be Grade 1 at all levels. In the older population, the prevalence of facet arthrosis is as high as 29.87% for the C4-C5 level. C4-C5 level appears to be affected the most frequently, followed by the C3-C4 level, then C2-C3, C5-C6, and C6-C7. The prevalence of cervical facet arthrosis increases with age, and occurs more commonly in the upper cervical spine.

  5. Improved marine reservoir age estimation and palaeoclimate synchronisation of the early Holocene Levantine/NW-Arabian region based on identification of the S1 tephra in Dead Sea and Tayma palaeolake sediments

    Due to a lack of tephras identified in marine and terrestrial palaeoclimate records from the Levantine-Arabian area, this region is still not sufficiently connected to the eastern Mediterranean tephrostratigraphical lattice. Here we report on the first finding of cryptotephra in the Holocene lacustrine sediment records of the Dead Sea and the Tayma palaeolake (NW Arabian Peninsula). The major elemental chemistry of the rhyolitic glass shards proves this tephra identical to the distal 'S1 tephra' identified in the Yammoûneh palaeolake, Lebanon (Develle et al, 2009), in a marine sediment record from the SE Levantine basin (Hamann et al., 2010) and in the Sodmein Cave archaeological site in Egypt (Barton et al., 2015). The 'S1 tephra', most likely corresponding to the early Holocene 'Dikkartın' dome eruption of the Erciyes Daǧ volcano in central Anatolia, Turkey, has been dated in the marine record at 8830 ± 140 cal yr BP. We present new age estimates of the 'S1 tephra' based on radiocarbon dating of terrestrial plant remains (Migowski et al., 2004) and pollen concentrates (Dinies et al., 2015), which reveal modelled ages of 8939 ± 83 cal yr BP in the Dead Sea sediments and 9041 ± 254 cal yr BP in Tayma. This allows the estimation of an early Holocene marine reservoir age of ca. 320 years in the SE Levantine Sea. The timing of the volcanic eruption during the early Holocene humid period, which led to the formation of sapropel S1 in the Mediterranean Sea, and the identification of the 'S1 tephra' more than 1200 km to the south are crucial for the synchronisation of marine and terrestrial palaeoclimate records in the eastern Mediterranean region.

    The use of CRISPR/Cas9 as a genome-editing tool in various model organisms has radically changed targeted mutagenesis. Here, we present a high-throughput targeted mutagenesis pipeline using CRISPR/Cas9 technology in zebrafish that will make possible both saturation mutagenesis of the genome and large-scale phenotyping efforts. We describe a cloning-free single-guide RNA (sgRNA) synthesis, coupled with streamlined mutant identification methods utilizing fluorescent PCR and multiplexed, high-throughput sequencing. We report germline transmission data from 162 loci targeting 83 genes in the zebrafish genome, in which we obtained a 99% success rate for generating mutations and an average germline transmission rate of 28%. We verified 678 unique alleles from 58 genes by high-throughput sequencing. We demonstrate that our method can be used for efficient multiplexed gene targeting. We also demonstrate that phenotyping can be done in the F1 generation by inbreeding two injected founder fish, significantly reducing animal husbandry and time. This study compares germline transmission data from CRISPR/Cas9 with those of TALENs and ZFNs and shows that efficiency of CRISPR/Cas9 is sixfold more efficient than other techniques. We show that the majority of published "rules" for efficient sgRNA design do not effectively predict germline transmission rates in zebrafish, with the exception of a GG or GA dinucleotide genomic match at the 5' end of the sgRNA. Finally, we show that predicted off-target mutagenesis is of low concern for in vivo genetic studies. © 2015 Varshney et al.; Published by Cold Spring Harbor Laboratory Press.

  7. Inaccuracy and bias in adult skeletal age estimation: Assessing the reliability of eight methods on individuals of varying body sizes.

    Merritt, Catherine E

    2017-06-01

    Accurate age estimations are essential for identifying human skeletal remains and narrowing missing persons searches. This study examines how BMI, body mass, and stature influence inaccuracy and bias in adult skeletal age estimations obtained using eight methods. 746 skeletons from the Hamann-Todd and William Bass Collections were used. Underweight BMI, light body mass, and short-stature individuals have the most error associated with their age estimates and are consistently under-aged between 3 to 13years. Obese BMI, heavy body mass, and tall-stature individuals are consistently over-aged between 3 to 8.5years. The most reliable methods for smaller-bodied individuals are Kunos et al. (first rib) and Buckberry-Chamberlain (auricular surface); for individuals in the average range, İşcan et al. (fourth ribs) and Passalacqua (sacrum); and for larger-bodied individuals, İşcan et al., Passalacqua, and Rougé-Maillart et al. (auricular surface and acetabulum). Lovejoy et al. (auricular surface) and Suchey-Brooks (pubic symphysis) produce consistent inaccuracy and bias scores across all body size groups. The least reliable method for smaller-bodied individuals is İşcan et al.; for larger-bodied individuals, Buckberry-Chamberlain; and across all body size groups, DiGangi et al. (first rib).

  8. Beginnings and Importance of Romantic Wandering in mid-18th Century

    Directory of Open Access Journals (Sweden)

    Aleksandar Molnar

    2016-02-01

    Full Text Available In the article, the author is discussing the importance of the wandering experiences for the emergence of Romanticism in the mid-18th century. His point of view is that without such experiences the rising culture of novels would not be able to trigger the correspondent take off in romantic arts and philosophy. Only during wanderings in the unknown nature it was possible not only to contemplate the alternative universes reveled by novels, but also to feel the possibility of their existence. And the most precious experiences wanderings could offer were the experiences of the possibility that the golden age was not only part of a mythic past but could be re-established again. Romantic wanderings were always part of the search for such golden age and source of the urge to re-invent the alternative to the oppressive bourgeois society. Such a view on the importance of romantic wanderings the author tries to demonstrate on examples of Jean-Jacques Rousseau in France and Johann Gottfried Herder in Germany. He considers them as first Romantics (along with Johann Georg Hamann in Germany whose early wandering experiences shaped to a great extent their intellectual development and enabled them to engage passionately in battle with the ideals of Enlightenment.

    2017-02-01

    We report simulation results for scanning tunneling spectroscopy of gold-tipped CdSe nanodumbbells of lengths ˜27 Å and ˜78 Å. Present results are based on Bardeen, Tersoff, and Hamann formalism that takes inputs from ab initio calculations. For the shorter nanodumbbell, the current-voltage curves reveal negative differential conductance, the characteristic of a tunnel diode. This behaviour is attributed to highly localized metal induced gap states that rapidly decay towards the center of the nanodumbbell leading to suppression in tunneling. In the longer nanodumbbell, these gap states are absent in the central region, as a consequence of which zero tunneling current is observed in that region. The overall current-voltage characteristics for this nanodumbbell are observed to be largely linear near the metal-semiconductor interface and become rectifying at the central region, the nature being similar to its parent nanorod. The cross-sectional heights of these nanodumbbells also show bias-dependence where we begin to observe giant Stark effect features in the semiconducting central region of the longer nanodumbbell.

    1997-11-01

    A new experimental source for singly ionized alkali metal plasma is presented. This source extends the work of Asmussen et al. al.(J. Asmussen, R. Mallavarpu, J. R. Hamann, H. C. Park Proc. IEEE), 62, 109 (1974)on microwave cavity gas discharges to include Alkali Metals in an effort to provide a simple and inexpensive source of Barium plasma for spectroscopic investigation of plasma phenomena. The source consists of a cylindrical microwave cavity resonant in the TM_112 mode. Barium is vaporized in a specially designed oven and the vapor passed into the cavity through a small opening in one end. The cavity length is adjusted with a moveable plunger so as to maintain the plasma-cavity system in resonance with the 2.45 GHz magnetron feeding power into the cavity. By avoiding plasma resonances, unnecessary heating of the plasma is avoided. The plasma is magnetized (field strength 80-120 Gauss) and the plasma flows along the field lines through a mesh in the plunger and out into the experimental region of the vacuum chamber. This source design holds considerable promise for extension to higher magnetic field strengths.

    Idiopathic scoliosis is a 3-D deformation affecting the position of the spine in space. The regional deformity has been studied extensively but the local changes have not been widely investigated and this being mainly due to the rarity of anatomical specimens. The objective of this study was to identify a deformation pattern for idiopathic scoliosis. We thus studied one complete scoliotic specimen using a digitizing protocol developed by our research group. The anatomical specimen was selected from the Hamann-Todd Osteology Collection at the Cleveland Natural History Museum, which contains over 1,300 skeletons. We were also able to match this scoliotic specimen with one normal specimen for age, sex, race, height and weight. Each vertebra was measured by taking approximately 200 points on each surface. Parameters for each vertebra were then calculated from these sets of points. Each scoliotic vertebra was then compared with a corresponding normal vertebra of the matched specimen. We present the first findings of these measurements, which show pedicle and posterior elements changes that are thought to be secondary to the scoliotic deformation.

    Full Text Available The origin of ferromagnetism in nanoparticles of nonmagnetic oxides is an interesting area of research. In the present work, transport properties of niobium thin films, with β-Ga2O3 nanoparticles embedded within them, are presented. Nanoparticles of β-Ga2O3 embedded in a Nb matrix were prepared at room temperature by radio frequency co-sputtering technique on Si (100 and glass substrates held at room temperature. The thin films deposited on Si substrates were subjected to Ar annealing at a temperature range of 600-650 C for 1 hour. Films were characterized by X-ray diffraction (XRD, Micro-Raman and elemental identification was performed with an Energy Dispersive X-ray Spectroscopy (EDS. Transport measurements were performed down to liquid helium temperatures by four-probe contact technique, showed characteristics analogous to those observed in the context of a Kondo system. A comparison of the experimental data with the theoretical formalism of Kondo and Hamann is presented. It is suggested that this behavior arises from the existence of magnetic moments associated with the oxygen vacancy defects in the nanoparticles of the nonmagnetic oxide Ga2O3.

  13. Common neural correlates of emotion perception in humans.

    Whether neuroimaging findings support discriminable neural correlates of emotion categories is a longstanding controversy. Two recent meta-analyses arrived at opposite conclusions, with one supporting (Vytal and Hamann []: J Cogn Neurosci 22:2864-2885) and the other opposing this proposition (Lindquist et al. []: Behav Brain Sci 35:121-143). To obtain direct evidence regarding this issue, we compared activations for four emotions within a single fMRI design. Angry, happy, fearful, sad and neutral stimuli were presented as dynamic body expressions. In addition, observers categorized motion morphs between neutral and emotional stimuli in a behavioral experiment to determine their relative sensitivities. Brain-behavior correlations revealed a large brain network that was identical for all four tested emotions. This network consisted predominantly of regions located within the default mode network and the salience network. Despite showing brain-behavior correlations for all emotions, muli-voxel pattern analyses indicated that several nodes of this emotion general network contained information capable of discriminating between individual emotions. However, significant discrimination was not limited to the emotional network, but was also observed in several regions within the action observation network. Taken together, our results favor the position that one common emotional brain network supports the visual processing and discrimination of emotional stimuli. © 2015 Wiley Periodicals, Inc.

    2015-01-01

    Accurate age estimations are essential to archaeological and forensic analyses. However, reliability for adult skeletal age estimations is poor, especially for individuals over the age of 40 years. This is the first study to show that body size influences skeletal age estimation. The İşcan et al., Lovejoy et al., Buckberry and Chamberlain, and Suchey-Brooks age methods were tested on 764 adult skeletons from the Hamann-Todd and William Bass Collections. Statures ranged from 1.30 to 1.93 m and body masses ranged from 24.0 to 99.8 kg. Transition analysis was used to evaluate the differences in the age estimations. For all four methods, the smallest individuals have the lowest ages at transition and the largest individuals have the highest ages at transition. Short and light individuals are consistently underaged, while tall and heavy individuals are consistently overaged. When femoral length and femoral head diameter are compared with the log-age model, results show the same trend as the known stature and body mass measurements. The skeletal remains of underweight individuals have fewer age markers while those of obese individuals have increased surface degeneration and osteophytic lipping. Tissue type and mechanical loading have been shown to affect bone turnover rates, and may explain the differing patterns of skeletal aging. From an archaeological perspective, the underaging of light, short individuals suggests the need to revisit the current research consensus on the young mortality rates of past populations. From a forensic perspective, understanding the influence of body size will impact efforts to identify victims of mass disasters, genocides, and homicides. © 2014 Wiley Periodicals, Inc.

    Whereas there is substantial information on the changes of the rib cage during childhood and asymmetry of the thorax in children with scoliosis, there are virtually no normative data on the growth of individual ribs throughout childhood. The Hamann-Todd (HT) Osteological Collection provided the bones of 32 human specimens aged 1-18 years. A total of 6,226 individual photographs of all vertebral bodies and ribs were obtained from these specimens. Quantitative measurements were taken with image analysis software and the results of 2 of the measurements, the outer costal length (OCL) and the base diameter (BD), are presented here. With the exception of the ribs at T12, both the OCL and BD showed linear, statistically significant growth with age for all ribs. The relationship of OCL and BD to each other within each rib was obtained by multiplying and dividing these 2 measurements. The BD × OCL product indicates that the ribs grow through coupled symmetry, by which ribs in the upper and lower thorax start at the same size and grow at the same rate within the pair; ribs 1 and 12, 2 and 11, and 3 and 10. Each rib pair grows at a significantly different rate from all other pairs. Measurements of BD and OCL from a specimen with scoliosis from the collection compared with these normative values were greatly different. The principle that ribs resemble a known geometric form, called the logarithmic spiral, is introduced. This article is 1 of the first studies of the change in length and shape of normal ribs in an osteology collection of a wide age range of pediatric specimens. The data provide a framework for determining the difference between ribs from normal children and those with scoliosis. Copyright © 2015 Scoliosis Research Society. Published by Elsevier Inc.

    The etiology of slipped capital femoral epiphysis (SCFE) is multifactorial, but the role of sagittal balance of the pelvis as a contributing factor to its development has not been well studied. Our primary purpose was to determine whether a smaller pelvic incidence (PI), a position-independent anatomic parameter that regulates pelvic orientation, could be a factor that increases shear stress in the epiphyseal growth plate and potentially contributes to the development of SCFE. We also set out to determine whether acetabular retroversion was associated with SCFE. We obtained 14 cadaveric pelvi from the Hamann-Todd Osteological Collection whose femurs showed evidence of post-SCFE deformity. Two hundred age-matched, sex-matched, and race-matched pelvi were used as controls. PI and acetabular version were measured using standardized lateral photographs and goniometers, respectively. T tests were performed to evaluate for differences in measured parameters between groups. The mean PI was 40.6±6.1 degrees for SCFE specimens and 47.4±9.9 degrees for normal specimens (P=0.01). The mean version of SCFE and normal acetabula was 15±7 and 17±6 degrees, respectively (P=0.39). There was also no significant difference in version between SCFE acetabula and the contralateral, uninvolved acetabular of the same specimen (15±7 vs. 17±8 degrees, P=0.33). Specimens with SCFE deformity demonstrated a smaller PI than a large cohort of normal control specimens. We found no significant difference between acetabular version of specimens with and without SCFE deformity. Contralateral or unaffected acetabuli of SCFE specimens were not more retroverted than the affected side of the same specimen. Sagittal balance of the pelvis, and particularly decreased PI, may play an important role in the development of SCFE. The influence of mechanical factors beyond the hip joint in the development of SCFE should be considered by clinicians.

  17. Ab initio STM and STS simulations on magnetic and nonmagnetic metallic surfaces

    The aim of this work was to provide an in-depth understanding of a new generation of scan- ning tunneling microscopy experiments, performed employing different regimes of the STM: the spectroscopy-mode (the so-called Fourier Transformed STM, FT-STM), and the spin-sensitive mode (the so-called spin-polarized STM, SP-STM). In the present thesis ab initio tools are proposed that are based on DFT calculations to theoretically predict and analyze such types of the STM. The first part of this thesis focusses on the simulation of FT-STM, the mode that allows to probe local dispersion properties of the electrons at the surface. In order to provide the theoretical counterpart of the experimental FT-STM spectra we have introduced a new implicit approach that is derived from Tersoff-Hamann theory of the STM. The importance of an accurate description of surface wavefunctions at 5-15 A above the surface as well as the spurious quantum- size effects have been discussed in detail together with approaches to obtain converged FT-STM images. We applied our method to FT-STM experiments performed on Ag(110) surfaces. In the second part of the thesis we discuss the modeling of the spin-resolved STM, the mode that allows to characterize the magnetic structure of a surface. As a case system we studied here the magnetically-ordered transition-metal nitride surface Mn{sub 3}N{sub 2}(010). Because SP-STM experiments did not allow a conclusive understanding of the surface structure, we have first employed ab initio thermodynamics to figure out the most stable magnetic and atomic configuration of the surface that are consistent with experiments. To simulate SP-STM images on the most stable Mn{sub 3}N{sub 2}(010) surface we have employed the spin-generalized transfer-Hamiltonian formalism, assuming that the tip wavefunctions have dominant radial symmetry (s-like tip).

    A big data geospatial analytics platform:Physical Analytics Information Repository and Services (PAIRS)Fernando Marianno, Levente Klein, Siyuan Lu, Conrad Albrecht, Marcus Freitag, Nigel Hinds, Hendrik HamannIBM TJ Watson Research Center, Yorktown Heights, NY 10598A major challenge in leveraging big geospatial data sets is the ability to quickly integrate multiple data sources into physical and statistical models and be run these models in real time. A geospatial data platform called Physical Analytics Information and Services (PAIRS) is developed on top of open source hardware and software stack to manage Terabyte of data. A new data interpolation and re gridding is implemented where any geospatial data layers can be associated with a set of global grid where the grid resolutions is doubling for consecutive layers. Each pixel on the PAIRS grid have an index that is a combination of locations and time stamp. The indexing allow quick access to data sets that are part of a global data layers and allowing to retrieve only the data of interest. PAIRS takes advantages of parallel processing framework (Hadoop) in a cloud environment to digest, curate, and analyze the data sets while being very robust and stable. The data is stored on a distributed no-SQL database (Hbase) across multiple server, data upload and retrieval is parallelized where the original analytics task is broken up is smaller areas/volume, analyzed independently, and then reassembled for the original geographical area. The differentiating aspect of PAIRS is the ability to accelerate model development across large geographical regions and spatial resolution ranging from 0.1 m up to hundreds of kilometer. System performance is benchmarked on real time automated data ingestion and retrieval of Modis and Landsat data layers. The data layers are curated for sensor error, verified for correctness, and analyzed statistically to detect local anomalies. Multi-layer query enable PAIRS to filter different data

Although this skin problem was initially described on the face, the scalp is often affected. A sensitive scalp can react with irritation to harsh surfactants or other additives which are often present in shampoos. For this reason, we developed a new rinse-off hypertolerant shampoo specifically designed for the hypersensitive and problematic scalp.Methods: The shampoo formulation is based on an extremely mild surfactant system and contains bisabolol, an anti-irritant and anti-inflammatory ingredient of chamomile. The shampoo is free of additives such as perfumes, silicones, colorants, parabens, paraffins, and betaine. Since skin can remain in a hyperreactive state after wounding, the status after hair transplantation was chosen as a model system to test the shampoo. Scalp condition and compatibility of each volunteer were analyzed by a plastic surgeon directly after hair transplant and after stitch removal. The plastic surgeons also rated whether they would recommend the further use of the test shampoo. Additionally, volunteers completed a self-assessment questionnaire.Results: Following hair transplantation, regular use of the shampoo resulted in a significant reduction in the extent of scabbing and erythema. This was confirmed by dermatological scalp examinations performed by the plastic surgeon as well as in volunteers' self-assessments. The plastic surgeon highly recommended the further use of the test shampoo after hair transplant to all study participants.Conclusion: Application of the test shampoo demonstrated excellent skin compatibility and product efficacy after hair transplant.

    This article highlights how the preservation of heritage languages is essential in the construction of three Georgia Latina participants' cultural identities and the creation of support networks that allow them to develop resiliency and achieve academically. We conceptualize resiliency as a strategy developed by the Latina participants using contextually mitigating factors during their STEM education. The findings presented in this manuscript are part of a larger, ongoing study of Latina resiliency and their paths to success in STEM fields in two states: Georgia and Texas. Following James Spradley's guidelines, data were collected via three separate semi-structured interviews with each participant. Intrinsic, multiple case studies were used to find both commonalities and differences, as well as to deepen our understanding of the role of the participants' heritage language in their development of resiliency in each particular case. The findings presented here were not part of a preconceived research hypothesis, but rather a theme that emerged while analyzing data collected in the state of Georgia. Georgia is not home to a long-established Hispanic/Latino population, but rather is part of the New Latino Diaspora (Wortham, Murillo and Hamann in Education in the new Latino diaspora: policy and the politics of identity. Ablex Publishing, New York, 2002), and therefore local natives do not necessarily perceive Latino immigrants and the Spanish language either as long-standing or permanent features of the state. In fact, in response to the growing diversity of the state during the past generation, Georgia has implemented multiple educational policies hostile toward immigrants and linguistic diversity (Beck and Allexsaht-Snider in Education in the new Latino diaspora: policy and the politics of identity. Ablex Press, Westport, 2002). Our findings suggest that the Latina participants' heritage languages allow them to engage in cultural traditions, encouraged by their

    Reference is made in the literature to the inherent instability of the atlantooccipital joint in infants and young children because of pliant ligaments, undeveloped musculature, smaller condyles, and the relative lack of anteroposterior curvature of the superior articular facet surfaces of the atlas. The combination of these morphologic factors is purported to make this population particularly vulnerable to whiplash-type injuries. Although a significant difference in the magnitude of the anteroposterior curvature of the superior articular facet surfaces of the atlas between young children and adults has been observed, quantitative analysis of the curvature of these surfaces has not been documented. To quantify the anterior to posterior curvature of the superior articular facet surfaces of the atlas as a function of age. This study is a retrospective analysis of the anterior to posterior curvature of the superior articular facet surfaces of the atlas as a function of age in 15 pediatric cadaver specimens from the Hamann-Todd Osteology Collection in Cleveland, Ohio, and 18 adult cadaver specimens from the Department of Experimental Anatomy in Brussels, Belgium. A stylus, connected to a three-dimensional digitizer, was used to manually define a series of points on the perimeter of the superior articular facet surfaces of the atlas of each specimen. The digitized data points were then used to generate two planes that approximated the anterior and posterior aspects of the articular surfaces in three-dimensional space. A line through a point on each plane and perpendicular to that plane was defined for each of the two planes. The angle between the two perpendicular lines was calculated and used to quantify the curvature of the facet surface. The anteroposterior curvature of the superior articular facet surfaces of the atlas increases from an average angle of 11.5 (±4.7) degrees at 1 year of age and asymptotically approaches an average angle of 43.5 (±13.4) degrees at

    The zygomaticofacial/temporal/orbital nerve is a terminal branch of the zygomatic nerve and exits the orbit through zygomatic foramina. The nomenclature in the literature varies with some studies identifying all 3 foramina on the malar surface of the zygoma, while others describe each along different aspects of the zygoma. In this study, foramen on the malar surface of the zygoma is termed zygomatic foramen, and the authors describe anatomical variations in the position and number of these foramina in an African American population. Sixty-two African American skulls from the Hamann-Todd collection of the Cleveland Museum of Natural History were studied. The primary outcome was the number of zygomatic foramina on the malar surface of the zygomatic bone. Secondary outcomes included the location of foramina relative to the orbital rim and the frontozygomatic suture. Mean and standard deviation were used to describe measurements. Chi-squared and Wilcoxon signed rank tests were used to analyze measurements between left and right hemicrania. The average number of foramina was 1.98 ± 0.93. More foramina were found on the right (2.13 ± 0.98) when compared with the left (1.68 ± 0.79; p = 0.001). The average distance between the lateral-most and medial-most foramina was 9.7 ± 5.0 mm. The distance from the orbital rim to the lateral foramen was 8.4 ± 4.2 mm, and distance from the orbital rim to the medial foramen was 7.7 ± 2.1 mm. The frontozygomatic suture was 22.9 ± 3.9 mm from the lateral foramen and 27.9 ± 3.6 mm from the medial foramen. The locations of the foramina in relation to the frontozygomatic suture and orbital rim were consistent with other populations. However, in this African American population, more zygomatic foramina were noted compared with previously published results in Korean, Indian, Brazilian, and West Anatolian populations. Surgeons should be cognizant of zygomatic foramina in this population to reduce potential neurovascular complications.

    An anatomic and biomechanical bench-top basic scientific comparative analysis to determine the appropriateness of total disc replacement (TDR) in a lumbar spine with scoliotic tendencies. Only limited data are currently available studying the application of disc replacement adjacent to scoliosis fusions. Theoretically, motion preservation should help delay the continuum of lumbar degeneration adjacent to scoliosis fusions and rotationally unstable lumbar segments. As a tertiary referral center for failed TDR, we noticed an alarming number of lumbar spinal rotational iatrogenic instability patterns but none occurring in the cervical spine. It is appropriate to analyze the bench-top rotational stability of disc replacement to predict whether this new technology is feasible for a larger prospective clinical study in the treatment of degenerative scoliosis. Measurements were taken from 60 human specimens from the Hamann-Todd Osteological Collection: 1) to determine the rotational arc of influence (AOI) = the angle formed from the center of axial rotation to the outermost extent of the facet joints; and 2) to determine the relative anatomic size discrepancy between the left and right facets proportionately with the cross-sectional area of the intervertebral disc = facet/endplate ratio (FER). Biomechanical testing was performed using fresh frozen human cadaveric spines with the following conditions to determine the rotational stability: 1) intact; 2) resection of ALL, anulus, disc, and PLL simulating the preparation for a TDR; 3) a more radical anular resection; 4) entire 360 degrees anular resection; and 4) insertion of the respective unconstrained-type disc replacement. Using a 6 degrees of freedom spine simulator, unconstrained pure moments of +/-8.0 Nm (lumbar) and +/-3.0 Nm (cervical) were used for axial rotation with quantification of the operative level range of motion and neutral zone, with data normalized to the intact spine condition. There were anatomic

    Secular changes refer to short-term biological changes ostensibly due to environmental factors. Two well-documented secular trends in many populations are earlier age of menarche and increasing stature. This study synthesizes data on maximum clavicle length and fusion of the medial epiphysis in 1840-1980 American birth cohorts to provide a comprehensive assessment of developmental and morphological change in the clavicle. Clavicles from the Hamann-Todd Human Osteological Collection (n = 354), McKern and Stewart Korean War males (n = 341), Forensic Anthropology Data Bank (n = 1,239), and the McCormick Clavicle Collection (n = 1,137) were used in the analysis. Transition analysis was used to evaluate fusion of the medial epiphysis (scored as unfused, fusing, or fused). Several statistical treatments were used to assess fluctuations in maximum clavicle length. First, Durbin-Watson tests were used to evaluate autocorrelation, and a local regression (LOESS) was used to identify visual shifts in the regression slope. Next, piecewise regression was used to fit linear regression models before and after the estimated breakpoints. Multiple starting parameters were tested in the range determined to contain the breakpoint, and the model with the smallest mean squared error was chosen as the best fit. The parameters from the best-fit models were then used to derive the piecewise models, which were compared with the initial simple linear regression models to determine which model provided the best fit for the secular change data. The epiphyseal union data indicate a decline in the age at onset of fusion since the early twentieth century. Fusion commences approximately four years earlier in mid- to late twentieth-century birth cohorts than in late nineteenth- and early twentieth-century birth cohorts. However, fusion is completed at roughly the same age across cohorts. The most significant decline in age at onset of epiphyseal union appears to have occurred since the mid

This survey aims at deriving the star formation histories, masses and metallicities of star formation galaxies at redshifts between 2.0-2.5 and also at deriving the properties (e.g., black hole masses) of AGN and at studying the optically obscured AGN at intermediate to high redshifts (z > 1.5). Joern was largely responsible for the target selection strategies for both samples (star-forming galaxies and AGN), for coordinating the weekly group meetings, and for designing a web-page for the extragalactic group. He was interested in using the survey to answer several cosmological questions in collaboration with Vicki Sarajedini, Rafael Guzmän, Fred Hamann, Anthony Gonzalez, the Flamingos-2 instrument PI, Stephen Eikenberry (all from UF), and with additional collaborators from the Complutense University of Madrid, Spain. Joern also worked with Vicki Sarajedini on SED fitting of variability-selected AGN in the Chandra Deep Field South. Joern was a very versatile observer, complementing his belief that understanding of the star-formation activity in galaxies can be only achieved through a multi-wavelength study of various galaxy types. In addition to research, Joern had a strong desire to be involved in the logistical aspects of science. At STScI he participated in the support group for the time allocation committee and at UF he was the postdoctoral representative of the space allocation committee. He photographed the UF staff for the departmental webpage and was a designated photographer at a local conference and other events. He also participated in the public Museum nights at UF. He was always eager to provide his feedback on the scientific and practical issues of astronomy and filled in many surveys distributed to the astronomical community. His colleagues and friends could always count on Joern to be extremely
