Attosecond-Scale Probing of the Electron Motion in the H-Atom Groundstate  [PDF]
Gerald Rosen
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312230
Abstract: Based on recent advances in attosecond strong-field spectroscopy and the current feasibility for trapping individual groundstate H-atoms from a neon-gas matrix, an experiment to probe the groundstate motion of the electron in the H-atom is proposed here.
Humanoid Robots That Behave, Speak, and Think Like Humans:A Reduction to Practice RRC-Humanoid Robot  [PDF]
Alan Rosen, David B. Rosen
Engineering (ENG) , 2015, DOI: 10.4236/eng.2015.71001
Abstract: A radical new approach is presented to programming human-like levels of Artificial Intelligence (AI) into a humanoid robot equipped with a verbal-phoneme sound generator. The system shares 3 important characteristics with human-like input data and processing: 1) The raw data and preliminary processing of the raw data are human-like. 2) All the data are subjective, that is related and correlated with a robotic self-identity coordinate frame. 3) All the data are programmed behaviorally into the system. A multi-tasking Relational Robotic Controller (RRC)-Humanoid Robot, described and published in the peer-reviewed literature, has been specifically designed to fulfill those 3 characteristics. A RRC-controlled system may be behaviorally programmed to achieve human-like high I.Q. levels of subjective AI for the visual signals and the declarative-verbal words and sentences heard by the robot. A proof of concept RRC-Humanoid Robot is under development and present status is presented at the end of the paper.
Hypoxia-inducible factors and the prevention of acute organ injury
Samuel N Heyman, Seymour Rosen, Christian Rosenberger
Critical Care , 2011, DOI: 10.1186/cc9991
Abstract: Increased expression of heme-oxygenase (HO)-1, heat-shock proteins (HSP), growth factors such as vascular endothelial factor (VEGF), and erythropoietin (EPO) are among the numerous adaptive responses to sublethal injury that are believed to participate in tissue tolerance during subsequent stress. EPO, for instance, is a ubiquitous pleiotropic survival and growth factor that attenuates experimental acute injury in various organ systems, including neuronal, retinal, cardiac, renal, and hepatic tissues. Its clinical efficacy, though suggested in critically ill patients, is yet to be defined [1].The expression of these protective mediators and many others is regulated by hypoxia-sensing mechanisms through the induction and stabilization of so called hypoxia-inducible factors (HIF) [2]. In this chapter, we will outline the control and action of HIF as key regulators of hypoxic adaptive response, and particularly examine HIF expression during hypoxic stress. We shall discuss recently developed measures that enable HIF signal modification and describe their potential use in conferring tissue tolerance during incipient organ injury.HIFs are heterodimers (Figure 1), composed of a constitutive β-subunit (HIF-β) and one of three different oxygen-dependent and transcriptionally active α-subunits, among which HIF-1α and -2α are acknowledged as promotors of hypoxia adaptation, whereas the role of HIF-3α remains unclear. Under normoxia, HIF-α subunits are constantly produced, but not allowed to accumulate, since they are rapidly hydroxylated by oxygen-dependent HIF prolyl-4-hydroxylase domain enzymes (PHD), subsequently captured by the ubiquitin ligase Von-Hippel-Lindau protein (VHL), and degraded by the proteasome. Under oxygen deficiency, PHD activity is reduced, HIF-α accumulates within the cytosol, αβ-dimers are formed, translocate into the nucleus, and bind to hypoxia response elements (HREs) in the promoter enhancer region of genes, which are subsequently transactivated [2-
Journal of astonishment – a tool to increase satisfaction with exchange programmes
Claus H. Reinhardt,Evelyne N. Rosen
Research in Learning Technology , 2012, DOI: 10.3402/rlt.v20i0.19185
Abstract: Many medical students use exchange programmes to enrich their portfolio. However, such a confrontation with reality can be challenging because custom and practice sometimes differ radically between countries. Exchange students post specific peculiarities, as encountered by them abroad, onto the medical exchange website. They can ask for the community's help and are expected to describe the (preliminary) solution that they have found. The “journal of astonishment” is structured by country and is designed not only to provide help for current exchange students but also to prepare future students for their stay abroad. Upon conclusion of the exchange, its satisfaction to both student and host institution is evaluated. Following the intervention, non-illness related drop out rates decreased by nearly 30% and student satisfaction improved by 1.7 points on a 10-point satisfaction scale. Host academic institution satisfaction also increased. Postings from the community were considered helpful. Female students especially benefited from the exchange website when preparing for their exchange. The journal of astonishment thus helps students better to select and prepare for an exchange with a particular academic institution. Moreover, the interactive web-based platform can provide spontaneous assistance with problem handling. The journal of astonishment is a low-cost tool that enhances student and host academic institution satisfaction.
The evolving role of hyaluronic acid fillers for facial volume restoration and contouring: a Canadian overview
Muhn C,Rosen N,Solish N,Bertucci V
Clinical, Cosmetic and Investigational Dermatology , 2012,
Abstract: Channy Muhn,1 Nathan Rosen,1 Nowell Solish,2 Vince Bertucci,2 Mark Lupin,3 Alain Dansereau,4 Fred Weksberg,5 B Kent Remington,6 Arthur Swift71Division of Dermatology, McMaster University, Hamilton, Ontario, 2Division of Dermatology, New Women's College Hospital, Toronto, Ontario, 3Department of Dermatology and Skin Science, University of British Columbia, Vancouver, British Columbia, 4Private Practice, Repentigny, Québec, 5Department of Medicine, University of Toronto, Toronto, Ontario, 6Private Practice, Calgary, Alberta, Canada; 7St Mary's Hospital, McGill University, Montréal, Québec, CanadaAbstract: Recent advancements, including more versatile facial fillers, refined injection techniques and the adoption of a global facial approach, have contributed to improved patient outcome and increased patient satisfaction. Nine Canadian specialists (eight dermatologists, one plastic surgeon) collaborated to develop an overview on volume restoration and contouring based on published literature and their collective clinical experience. The specialists concurred that optimal results in volume restoration and contouring depend on correcting deficiencies at various layers of the facial envelope. This includes creating a foundation for deep structural support in the supraperiosteal or submuscular plane; volume repletion of subcutaneous fat compartments; and the reestablishment of dermal and subdermal support to minimize cutaneous rhytids, grooves and furrows. It was also agreed that volume restoration and contouring using a global facial approach is essential to create a natural, youthful appearance in facial aesthetics. A comprehensive non-surgical approach should therefore incorporate combining fillers such as high-viscosity, low-molecular-weight hyaluronic acid (LMWHA) for structural support and hyaluronic acid (HA) for lines, grooves and furrows with neuromodulators, lasers and energy devices.Keywords: hyaluronic acid filler, volumizing, facial rejuvenation
The Prospects for Renewable Energy through Hydrogen Energy Systems  [PDF]
Marc A. Rosen
Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.34050
Abstract:

The prospects for renewable energy are enhanced through the use of hydrogen energy systems in which hydrogen is an energy carrier. As easily accessible fossil fuel supplies become scarcer and environmental concerns increase, hydrogen is likely to become an increasingly important chemical energy carrier. As the world’s energy sources become less fossil fuel-based, hydrogen and electricity are expected to be the two dominant energy carriers for the provision of end-use services, in a hydrogen economy. Thus, hydrogen energy systems allow greater use of renewable energy resources. In this paper, the role of hydrogen as an energy carrier and hydrogen energy systems, and their economics, are described and reviewed.

Marc A. Rosen
Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.34065
Abstract:

Net-zero energy buildings and communities, which are receiving increasing interest, and the role of energy storage in them, are described. A net-zero energy building or community is defined as one that, in an average year, produces as much energy from renewable energy as it consumes. Net-zero energy buildings and communities and the manner in which energy sustainability is facilitated by them are described and examples are given. Also, energy storage is discussed and the role and importance of energy storage as part of net-zero buildings and communities are explained. The NSERC Smart Net-zero Energy Buildings Research Network, a major Canadian research effort in smart net-zero energy buildings and communities, is described.

The Dark Side of Emotional Intelligence  [PDF]
Adrian Furnham, Adrienne Rosen
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.73035
Abstract:

Over 300 British adults completed the Hogan Development Survey (HDS) (Hogan & Hogan, 2001), a measure of the personality disorders and the Bar-On Emotional Quotient Inventory (EQi) (Bar- On, 2004). Work associates known to the participants also completed an observers’ version of the EQi. The structures of both inventories were examined. The HDS factored into three clear factors (clusters A, B, C) confirming previous analyses while the EQi had a single factor structure. Cluster B disorders (labelled Moving Against People) were correlated negatively with the Stress scale on the EQi while Cluster A disorders (labelled Moving Away from People) were negatively correlated with Intrapersonal, Interpersonal and Mood subscale scores on the EQi. Regressions showed that Avoidant, Schizoid and Narcissistic disorders most consistently related to the self-reported EQi subscale scores. Interestingly Paranoia was positively correlated with the total and the Intrapersonal EQi scores. Participants tended to have higher self, compared to observer scores on the EQi. Only one regression was significant: participants with lower Borderline and Schizotypal scores were seen to be better at Stress management.

Insights into New Media Use by International Students: Implications for Cross-Cultural Adaptation Theory  [PDF]
Blake Hendrickson, Devan Rosen
Social Networking (SN) , 2017, DOI: 10.4236/sn.2017.62006
Abstract: The current study uses a longitudinal, mixed-method approach to investigate the role that new media, such as social networking sites and video chat, play in cross-cultural adaptation and international student friendship network development. Results indicate that international students significantly increase and adapt their new media use while abroad to communicate globally with their friends and family, and locally with their newly formed relationships. Furthermore, social networking site host national friends do not necessarily lead to the development of face-to-face host national friends; however, interaction with established face-to-face host national friends and friend groups via new media platforms leads to an increased understanding of host communication patterns. Finally, this study proposes that researchers who apply Kim’s [1] cross-cultural adaptation theory consider incorporating Host New Media Communication as a principal concept.
Global Models of the Galactic Interstellar Medium: Comparison to X-Ray and H I Observations
Alexander Rosen,Joel N. Bregman,Daniel D. Kelson
Physics , 1996, DOI: 10.1086/177915
Abstract: In a previous paper, we calculated numerical hydrodynamic models of the interstellar medium in the Galaxy, which suggested that hot gas (T $\ge$ 3 $\times$ 10$^5$ K) has a filling factor near 50\% in the midplane (Rosen \& Bregman 1995, ApJ 440, 634). Here we extend the work to examine the X-ray emission characteristics of the best model and calculate a variety of observable measures for comparison with the observed soft X-ray background. We calculate the X-ray intensities, spectra, and hardness ratios in two soft X-ray bands as Galactic latitude and cool gas column are varied, and make comparisons with observational data. The observed distribution of N$_{H I}$ is similar to that seen from one of the simulated bubbles, with the important exception that the minimum hydrogen column in the model is too low. Also, there are clear examples of anticorrelations between H I and X-ray emission as well as correlations between H I and X-rays, which is caused by an increased emission measure as a shock enters a cool gas region. Statistically, anticorrelations are slightly more common than correlations. X-ray spectra are calculated from the models and these reveal that for observations to have strong diagnostic power in probing the hot ISM, a spectral resolution of E/$\Delta$E $>$ 30 is required. This analysis demonstrates several shortcomings of our model, which may be solved by future simulations that include magnetic fields.
