    We study random knots and links in R^3 using the Petaluma model, which is based on the petal projections developed by Adams et al. (2012).

    In this model we obtain a formula for the distribution of the linking number of a random two-component link. We also obtain formulas for the expectations and the higher moments of the Casson invariant and the order-three knot invariant v3. These are the first precise formulas given for the distributions of invariants in any model for random knots or links.

    All terms above will be defined and explained.

    Joint work with Joel Hass, Nati Linial, and Tahl Nowik.

    An outstanding problem in medicine is to combat bacteria resistant to antibiotics and cancer cells resistant to chemotherapy treatments. Drug combinations are often used to counter resistance, but therapies developed on drug-sensitive cells often fail when applied to resistant mutants. The talk will describe a series of experiments and theoretical approaches using scaling arguments, to infer the response of resistant cancer cells and bacteria to multidrug treatments. I will show that general symmetry arguments are sufficient to unify the behaviors of drug-resistant and drug-sensitive cells. Experiments validate this approach, which holds for many cell types across several domains of life. Thus, such simplifying arguments may foster our understanding of drug resistance even before specific detailed biochemical mecha-nisms have been elucidated.

    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.
