Self‐Organized Origami Structures via Ion‐Induced Plastic Strain

Ion processing of the reactive surface of a free-standing polycrystalline metal film induces a flow of atoms into grain boundaries, resulting in plastic deformation. A thorough experimental and theoretical analysis of this process is presented, along with the demonstration of novel engineering concepts for precisely controlled 3D assembly at micro- and nanoscopic scales.

Short-term Memory for Repeated and Non-repeated Items

Digit sequences containing repeated items are retained differently in short-term memory from sequences containing no repeated items. The repeated items are remembered better or worse than items in the corresponding positions of “all-different” sequences depending on the number of times the item is repeated, the number of items repeated, the number of items intervening between the occurences of a repeated item, and the position of the repeated items in relation to the beginning and end of the sequence. In every type of repetition studied, except one, memory for the non-repeated items in sequences with repeated items is better than for the corresponding items of all-different sequences. This is true in some cases despite significant specific interference between the (non-repeated) items following the separated occurrences of repeated items. The negative effects in memory for repeated items and the positive effects in memory for non-repeated items are greater when the items are presented at the rate of five per sec. than at one per sec. , contrary to the hypothesis that differential rehearsal is responsible for these effects. The results are interpreted as supporting an “associative,” as opposed to a “non-associative,” theory of short-term memory, as this distinction is defined in the paper.
MODELING OF HOT-CARRIER DEGRADATION BASED ON THOROUGH CARRIER TRANSPORT TREATMENT

We present and validate a physics-based model for hot-carrier degra- dation. The model is based on a thorough carrier transport treatment by means of an exact solution of the Boltzmann transport equation. Such important in- gredients relevant for hot-carrier degradation as the competing mechanisms of bond dissociation, electron-electron scattering, the activation energy reduction due to the interaction of the dipole moment of the bond with the electric field as well as statistical fluctuations of this energy are incorporated in our approach. The model is validated in order to represent the linear drain current change in three different devices subjected to hot-carrier stress under different conditions. The main demand is that the model has to use a unique set of parameters. We analyze the importance of all the model ingredients, especially the role of electron-electron scattering. We check the idea that the channel/gate length of the device alone is not enough to judge whether electron-electron scattering is important or not and instead a combination of the device topology and stress conditions needs to be used.
Participative Goal Setting in Self-Directed Global Virtual Teams: The Role of Virtual Team Efficacy in Goal Setting Effectiveness and Performance

The frequent use of global virtual teams for accomplishing organizational tasks helps explain the continued interest in research designed to identify and disentangle the relationships among factors influencing team performance. Participative goal setting represents one factor that may be particularly important in these settings. 52 self-directed global virtual teams, consisting of 318 participants, were observed during the life cycle of a team project in order to examine these critical relationships. As hypothesized, results reveal that virtual team efficacy (VTE) indirectly relates to goal commitment through the participative process of setting specific and difficult goals. In turn, participatively setting difficult goals and the teams' commitment to those goals directly affects actual performance. These findings extend prior research applying social cognitive theory (SCT) in global virtual team research. Implications for theory and practice, as well as opportunities for future research are discussed.
Micropropagation of Scabiosa caucasica Bieb. Cv. Caucasica blue

SummaryMicropropagation of Scabiosa caucasica cv. Caucasica Blue was achieved by culturing, separating axillary and adventitious shoots, or node sectioning on Murashige and Skoog (MS) medium supplemented with benzyladenine (BA). The highest frequency of adventitious shoots regenerated from nodal or internodal explants and leaf blade (with or without petiole) appeared to occur on MS medium with 4.4 and 18 μM BA, respectively. Addition of 0.19 or 1.9 μM α-naphthaleneacetic acid to the BA-containing medium promoted callus formation and reduced shoot organogenesis. During micropropagation, shoot nodal explants derived from in vitro shoots cultured on MS medium supplemented with 4.4 μM BA yielded 8.9 shoots per explant within 40 d after culture initiation.
Accumulation of Amino Acid Substitutions Promotes Irreversible Structural Changes in the Hemagglutinin of Human Influenza AH3 Virus during Evolution

ABSTRACT In order to clarify the effect of an accumulation of amino acid substitutions on the hemadsorption character of the influenza AH3 virus hemagglutinin (HA) protein, we introduced single-point amino acid changes into the HA1 domain of the HA proteins of influenza viruses isolated in 1968 (A/Aichi/2/68) and 1997 (A/Sydney/5/97) by using PCR-based random mutation or site-directed mutagenesis. These substitutions were classified as positive or negative according to their effects on the hemadsorption activity. The rate of positive substitutions was about 50% for both strains. Of 44 amino acid changes that were identical in the two strains with regard to both the substituted amino acids and their positions in the HA1 domain, 22% of the changes that were positive in A/Aichi/2/68 were negative in A/Sydney/5/97 and 27% of the changes that were negative in A/Aichi/2/68 were positive in A/Sydney/5/97. A similar discordance rate was also seen for the antigenic sites. These results suggest that the accumulation of amino acid substitutions in the HA protein during evolution promoted irreversible structural changes and therefore that antigenic changes in the H3HA protein may not be limited.
CADASIL presenting with spontaneous intracerebral hemorrhage: report of a case and description of the first family in Northern Greece.

INTRODUCTION CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy), the most common inherited cause of stroke and dementia in adults, has been described in six Greek families. Common presenting manifestations include migraine with aura, brain ischemia, mood disorders and cognitive decline. Spontaneous intracerebral hemorrhage (SICH) rarely occurs in CADASIL and only exceptionally as the first clinical manifestation. CASE DESCRIPTION We have previously reported the sixth Greek family with CADASIL and in particular, two brothers in whom the genetic testing documented a classic mutation of the NOTCH3 gene (Arg169Cys). In this report, we describe the 30-year-old son of the second brother, who suffered a thalamic SICH as the presenting manifestation of CADASIL, in the absence of arterial hypertension or antiplatelet drug use. CONCLUSION Patients with acute subcortical infarcts, leukoencephalopathy, a history of migraine, mood disorders, and dementia, should always raise the suspicion of CADASIL. However, a SICH, even in the absence of classical risk factors for hemorrhage, is possible and should not exclude the diagnosis of CADACIL. Hippokratia 2016, 20(1): 76-79.
Planning for Quality

By being aware of one another's needs and roles in the process--even when situations changed--the system remained clear and supported change. We learned that when we see each other as customers and fully understand our customers' needs, our processes then acquire the adaptability they need to truly individualize patient care. The project team has continued to meet sporadically over the past year to improve the care processes for these patients. Elements of both the process and patient outcomes are being monitored as well. We feel that the application of CQI concepts and methods aided us in planning for quality. The encouragement this experience brought prompted us to become even more committed to full implementation of TQM. We now have a two-year training program underway to involve every employee and physician. Project teams are working on other processes such as preoperative teaching and vendor selection. We are beginning to appreciate the fundamental change that occurs when we plan for quality.
Sox10‐iCreERT2: A mouse line to inducibly trace the neural crest and oligodendrocyte lineage

SOX10 is a well‐conserved and widely expressed transcription factor involved in the regulation of embryonic development and in the determination of cell fate. As it is expressed in neural crest cells, their derivatives and the oligodendrocyte lineage, mutations of the protein contribute to a variety of diseases like neurocristopathies, peripheral demyelinating neuropathies, and melanoma. Here, we report the generation of an inducible Sox10‐iCreERT2 BAC transgenic mouse line that labels, depending on the timepoint of induction, distinct derivatives of the otic placode and the neural crest as well as cells of the oligodendrocyte lineage. Surprisingly, we could show a neural crest origin of pericytes in the brain. Besides its use for fate‐mapping, the Sox10‐iCreERT2 mouse line is a powerful tool to conditionally inactivate genes in the neural crest cells, their progeny and/or the oligodendrocyte lineage in a time‐dependent fashion to gain further insights into their function and contribution to diseases. genesis 50:506–515, 2012. © 2011 Wiley Periodicals, Inc.
Populations headed south? The Gravettian from a palaeodemographic point of view

Abstract The Gravettian is known for its technological innovations and artisanal craftwork. At the same time, continued climatic deterioration led to the coldest and driest conditions since the arrival of Homo sapiens sapiens in Europe. This article examines the palaeodemographic development and provides regionally differentiated estimates for both the densities and the absolute numbers of people. A dramatic population decline characterises the later part of the Gravettian, while the following Last Glacial Maximum experienced consolidation and renewed growth. The results suggest that the abandonment of the northern areas was not a result of migration processes, but of local population extinctions, coinciding with a loss of typological and technological complexity. Extensive networks probably assured the maintenance of a viable population.

Neben infektiosen HBV-Partikeln sekretieren infizierte Zellen auch sehr effizient nicht infektiose subvirale Partikel, die hauptsachlich aus dem HBV-Hullprotein S, bestehen. In Rahmen dieser Arbeit wurde die Bedeutung der transmembranen, luminalen und zytoplasmatischen Bereiche des S-Proteins hinsichtlich dessen Oligomerisierung und der HBV- und HDV-Partikelbildung untersucht und zum ersten Mal die Fahigkeit der TM2 zur Selbstinteraktion gezeigt sowie weitere essentielle Domanen und AS-Reste des S-Proteins identifiziert.
Effects of dietary energy and lysine levels on growth performance and carcass yields of Pekin ducks from hatch to 21 days of age

ABSTRACT A 2 × 6 factorial experiment, using 2 dietary apparent metabolizable energy (AME) levels (2,750 and 3,050 Kcal/kg) and 6 supplemental lysine (Lys) levels (0, 0.10, 0.20, 0.30, 0.40, and 0.50%), was conducted to study the effects of dietary energy and lysine levels on growth performance and carcass yields of Pekin ducks from hatch to 21 d of age. A total of 576 one‐day‐old male White Pekin ducks was randomly allotted to 12 dietary treatments, each containing 6 replicate pens with 8 birds per pen. At 21 d of age, body weight gain, feed intake, and feed/gain were measured, and then 2 ducks selected randomly from each pen were slaughtered to evaluate the yields of abdominal fat, breast meat, and leg meat. As a result, birds that were fed basal diets with no Lys supplementation showed growth depression, and significant positive effects of dietary Lys supplementation on body weight gain (P < 0.001), feed intake (P < 0.001), and feed/gain (P = 0.002) were observed as dietary Lys increased gradually among all the groups. In addition, increasing energy levels did not affect overall body weight gain (P > 0.05), but feed intake (P = 0.001) and feed/gain (P = 0.009) decreased significantly between the groups. Dietary Lys levels influenced the yields of breast (P < 0.001) and leg (P = 0.001) meat among all the groups, but dietary energy levels had a significant positive effect only on abdominal fat yield (P = 0.014). The interaction between dietary energy and Lys influenced body weight gain of ducks significantly (P = 0.004). According to the broken‐line regression analysis, Lys requirements of Pekin ducks for weight gain at 2,750 and 3,050 Kcal of AME/kg were 0.94 and 0.98%, respectively. It suggested that Lys requirement was higher at 3,050 Kcal of AME/kg than at 2,750 Kcal of AME/kg. Dietary energy content determined feed intake of the ducks, and high‐energy diets will require a higher amino acid concentration to compensate for a lower feed intake.
Mammalian Sprouty Proteins Inhibit Cell Growth and Differentiation by Preventing Ras Activation*

Sprouty was genetically identified as an antagonist of fibroblast growth factor signaling during tracheal branching in Drosophila. In this study, we provide a functional characterization of mammalian Sprouty1 and Sprouty2. Sprouty1 and Sprouty2 inhibited events downstream of multiple receptor tyrosine kinases and regulated both cell proliferation and differentiation. Using NIH3T3 cell lines conditionally expressing Sprouty1 or Sprouty2, we found that these proteins specifically inhibit the Ras/Raf/MAP kinase pathway by preventing Ras activation. In contrast, activation of the phosphatidylinositol 3-kinase pathway was not affected by Sprouty1 or Sprouty2. We further showed that Sprouty1 and Sprouty2 do no prevent the formation of a SNT·Grb2·Sos complex upon fibroblast growth factor stimulation, yet block Ras activation. Taken together, these results establish mammalian Sprouty proteins as important negative regulators of growth factor signaling and suggest that Sprouty proteins act downstream of the Grb2·Sos complex to selectively uncouple growth factor signals from Ras activation and the MAP Kinase pathway.
Study on the effective loading shape of magnetic sheet for receiver coil in WPT systems

Recently, Wireless Power Transmission (WPT) system in accordance with Qi standards is being installed into smartphones. However, the transmission efficiency is greatly deteriorated due to adjacent metal objects. To solve those problems, it is thought that the high permeability magnetic sheet insertion method into the gap between WPT-coil and metal objects is effective. On the other hand, the high permeability magnetic sheet (for instance, an amorphous magnetic sheet) has large loss as a negative feature. Therefore, to improve transmission efficiency of the WPT systems, and to suppress thickness of these materials, the magnetic loss control by trimming of the amorphous magnetic sheet is proposed in this report.
Industrial Cyberphysical Systems: A Backbone of the Fourth Industrial Revolution

Cyberphysical systems (CPSs) are perceived as the pivotal enabler for a new era of real-time Internetbased communication and collaboration among value-chain participants, e.g., devices, systems, organizations, and humans. The CPS utilization in industrial settings is expected to revolutionize the way enterprises conduct their business from a holistic viewpoint, i.e., from shop-floor to business interactions, from suppliers to customers, and from design to support across the whole product and service lifecycle. Industrial CPS (ICPSs) blur the fabric of cyber (including business) and physical worlds and kickstart an era of systemwide collaboration and information-driven interactions among all stakeholders of the value chain. Therefore, ICPSs are expected to empower the transformation of industry and business at large to a digital, adaptive, networked, and knowledge-based industry with significant long-term impact on the economy, society, environment, and citizens.
On the gravitational radiation from the collapse of neutron stars to rotating black holes

We provide details and present additional results on the numerical study of the gravitational-wave emission from the collapse of neutron stars to rotating black holes in three dimensions. More specifically, we concentrate on the advantages and disadvantages of the use of the excision technique and on how alternative approaches to that of excision can be successfully employed. Furthermore, as a first step towards source characterization, we present a systematic discussion of the influence that rotation and different perturbations have on the waveforms and hence on the energy emitted in gravitational waves.
The Ecological Genetics of Conditional Strategies

We develop a quantitative genetic model for conditional strategies that incorporates the ecological realism of previous strategic models. Similar to strategic models, the results show that environmental heterogeneity, cue reliability, and environment‐dependent fitness trade‐offs for the alternative tactics of the conditional strategy interact to determine when conditional strategies will be favored and that conditional strategies should be a common form of adaptive variation in nature. The results also show that conditional and unconditional development can be maintained in one of two ways: by frequency‐dependent selection or by the maintenance of genetic variation that exceeds the threshold for induction. We then modified the model to take into account variance in exposures to the environmental cue as well as variance in response to the cue, which allows a derivation of a dose‐response curve. Here the results showed that increasing the genetic variance for response both flattens and shifts the dose‐response curve. Finally, we modify the model to derive the dose‐response curve for a population polymorphic for a gene that blocks expression of the conditional strategy. We illustrate the utility of the model by application to predator‐induced defense in an intertidal barnacle and compare the results with phenotypic models of selection.
Pathology of Experimental Machupo Virus Infection, Chicava Strain, in Cynomolgus Macaques (Macaca fascicularis) by Intramuscular and Aerosol Exposure

Machupo virus, the causative agent of Bolivian hemorrhagic fever (BHF), is a highly lethal viral hemorrhagic fever of which little is known and for which no Food and Drug Administration–approved vaccines or therapeutics are available. This study evaluated the cynomolgus macaque as an animal model using the Machupo virus, Chicava strain, via intramuscular and aerosol challenge. The incubation period was 6 to 10 days with initial signs of depression, anorexia, diarrhea, mild fever, and a petechial skin rash. These were often followed by neurologic signs and death within an average of 18 days. Complete blood counts revealed leukopenia as well as marked thrombocytopenia. Serum chemistry values identified a decrease in total protein, marked increases in alanine aminotransferase and aspartate aminotransferase, and moderate increases in alkaline phosphatase. Gross pathology findings included a macular rash extending across the axillary and inguinal regions beginning at approximately 10 days postexposure as well as enlarged lymph nodes and spleen, enlarged and friable liver, and sporadic hemorrhages along the gastrointestinal mucosa and serosa. Histologic lesions consisted of foci of degeneration and necrosis/apoptosis in the haired skin, liver, pancreas, adrenal glands, lymph nodes, tongue, esophagus, salivary glands, stomach, small intestine, and large intestine. Lymphohistiocytic interstitial pneumonia was also present. Inflammation within the central nervous system (nonsuppurative encephalitis) was histologically apparent approximately 16 days postexposure and was generally progressive. This study provides insight into the course of Machupo virus infection in cynomolgus macaques and supports the usefulness of cynomolgus macaques as a viable model of human Machupo virus infection.
Scheme Of Certified Enterprises: Tool Or Barrier For Mipymes In Mexico (Esquema De Empresas Certificadas: Herramienta O Barrera Para Las Mipymes En Mexico)

This research analyzes the certification of Mexican companies within the New Scheme of Certified Companies. We consider the requirements for certification and the advantages of certification. We also an analyze the Equality Principle contemplated in article one of the Political Constitution of the United Mexican States according to the human rights reform of June 10, 2011. Our objective is to determine if the inactivity of the State regarding micro, small and medium-sized national companies, violates the Equality Principle established in the Constitution. We conclude that in the participation of State supporting companies, the principle of equality must prevail. Companies with lower economic capacity and engaged in foreign trade, must be included in the New Certified Companies Scheme
Global software development in practice lessons learned

More than a decade ago, organizations seeking lower costs and access to skilled resources began to experiment with remotely located software development facilities. This change is having a profound impact not only on marketing and distribution but also on the way products are conceived, designed, constructed, tested, and delivered to customers. The number of organizations distributing their software development processes worldwide keeps increasing. As a result, software development is becoming a multi-site, multicultural and globally distributed undertaking. More recently, attention has turned toward trying to understand the factors that enable multinationals and virtual corporations to operate successfully across geographic and cultural boundaries. On the basis of these factors, we present the lessons learned from case studies in two software development units from multinational organizations located in Brazil.
