    Imposing a curved shape on a solid sheet, generates in it elastic stress. This familiar motif is a consequence of Gauss’ theorema Egregium, which posits that there exists no isometric map between two surfaces of different Gaussian curvatures. This coupling between geometry (curvature) and mechanics (stress) underlies the morphological richness observed in solid sheets, and their nontrivial response to exerted forces.

    In this talk I will attempt to provide a unifying framework of this geometry-mechanics interplay, by demonstrating basic mechanisms through which a Gaussian curvature can (or cannot) be accommodated by solid sheets. A few examples will be discussed: a sheet attached to liquid drop, a twisted ribbon, and the indentation of a floating sheet.

    Walking was once considered to be an automatic task that requires minimal higher-level cognitive input. This presentation will briefly review emerging evidence that links cognitive function to gait and fall risk in healthy adults and in patients with neurodegenerative disease. We will attempt to explain why certain gait alterations predict the development of dementia and why safe ambulation depends on executive function and attention. Building on those insights, we describe preliminary findings that illustrate the potential of novel therapeutic approaches for enhancing mobility and cognition and for reducing fall risk. A final example illustrates that a motor-cognitive intervention may promote beneficial neural plasticity in frontal lobe activation during complex walking conditions.

    I will present high-resolution spectrophotometric imaging of Balmer-dominated shocks (BDSs) around two historical supernova remnants SN1006 and Tycho. BDSs are characterized by strong hydrogen emission lines with a narrow (~10 km/s) and a broad (~ 1000 km/s) component. Using integral-field spectroscopy and Fabry-Perot interferometry we spatially resolve the shocks and minimize the shock geometry contribution to Halpha-line profiles. In the case of SN1006, we find significant variations in broad line widths and broad-to-narrow line intensity ratios across the shock that point towards the presence of suprathermal protons – seeds of high-energy cosmic ray protons. In Tycho, our observations indicate an additional intermediate-width (~ 100 km/s) component, implying the presence of a fast-neutral precursor. Moreover, in the latter case the narrow component is typically broader than the maximally expected 20 km/s and is sometimes even double-peaked, which might be due to a cosmic ray precursor and/or the shock geometry. Application of state-of-the-art shock models that include non-thermal physics to the presented data are expected to provide important constraints on the shocks and hadronic cosmic ray properties.

    תקציר: התאבדות היא תופעה אנושית שחוצה תרבויות ותקופות הנחקרת במסגרת דיסציפלינות רבות ומגוונות. למרות המאמץ הרב-תחומי הענף לפענח את התופעה, היא נותרת במובנים רבים חידתית ונטולת הסבר מְספק. העיסוק בתופעת ההתאבדות נפוץ מאוד בעולם היצירה הספרותית, כביטוי נוסף לניסיון הבלתי נלאה לפענח ולמשמע את החריגה המתגלמת בהתאבדות מסדריו הנורמטיביים של הקיום האנושי. אקט ההתאבדות הוא כשלעצמו אתר של עימות בין כוחות סותרים רבי עוצמה, דהיינו דחף החיים אל מול יצר המוות, והוא עשוי להיקרא גם כבעל משמעויות עמוקות בכל הנוגע ליצר החיים המתבטא ביצירה האמנותית בכלל ובכתיבה בפרט. קריאת מעשה ההתאבדות הספרותית עשויה לשפוך אור על אתרים "אפלים" בנפש האדם ועל האופן שבו הספרות עשויה להעניק להם מילים ולפענח אותם. מחקרי מתחקה אחר ייצוגים של התאבדות במבחר יצירות בפרוזה מן הספרות העברית המודרנית תוך הפניית מבט סינכרוני ודיאכרוני אל ייצוגיה של התופעה בהקשרים הפסיכולוגיים, החברתיים והפוליטיים, וכן אל תפקידה התמטי והאסתטי בטקסט הספרותי. מטרתו של המחקר היא לבחון את מעשה ההתאבדות כפי שהוא מיוצג בספרות כנקודת מפגש עוצמתית ומיוחדת במינה בין כוחות מנוגדים חברתיים, פוליטיים ופסיכולוגיים. בהקשר הספציפי של הספרות העברית, שמתוכה נבחר קורפוס המחקר, ושעניינה המתמשך הינו התהליכים ההיסטוריים שעברה תנועת התחייה הלאומית מסוף המאה התשע-עשרה ועד היום, מצטרף דיון זה אל הניסיון המחקרי-תיאורטי הקיים לשרטט את יחסי הגומלין המשתנים בין הקולקטיבי לאינדיווידואלי בתרבות העברית המתחדשת.

    Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, we found that chiral organic molecules can act as spin filters for photoelectrons transmission, in electron transfer, and in electron transport. The effect introduces the ability to utilize quantum mechanical phenomena at room temperature.
    The new effect, termed Chiral Induced Spin Selectivity (CISS)1 has interesting implications for the production of new types of spintronics devices and on electron transfer in biological systems. The effect was found in bio-molecules and in bio-systems like the photosystem I. It will be shown how the CISS effect makes electron transfer in Biology more efficient and how it may be important in redox reactions. The basic effect, and its applications and implications, will be presented including a quantitative theory that explains the effect.
