Optimal polynomial blow up range for critical wave maps

We prove that the critical Wave Maps equation with target

S^2

and origin ℝ

^{2+1}

admits energy class blow up solutions of the form [ u(t, r) = Q(\lambda(t)r) + \epsilon(t, r) ] where

Q:ℝ²\rightarrow S^2

is the ground state harmonic map and $\lambda ...

Energy Challenges in the Global South

Silvia Hostettler

Energy needs at the global level are gigantic and steadily increasing while the need to reduce carbon emissions is vital if catastrophic climate change is to be avoided. In the Global South, a large part of the population still lacks access to energy, whic ...

Three-Component Povarov Reaction–Heteroannulation with Arynes: Synthesis of 5,6-Dihydroindolo[1,2‑a]quinolines

Qian Wang, Jieping Zhu, Ala Bunescu

A reaction of 2-acyl substituted tetrahydroquinolines, prepared by Lewis acid-catalyzed three-component reaction of α-oxo aldehydes, anilines, and dienophiles, with in situ generated arynes afforded 5,6-dihydroindolo[1,2-a]- quinolines in good to excellent ...

Bounded Tamper Resilience: How to go beyond the Algebraic Barrier

Sebastian Faust

Related key attacks (RKAs) are powerful cryptanalytic attacks where an adversary can change the secret key and observe the effect of such changes at the output. The state of the art in RKA security protects against an a-priori unbounded number of certain a ...

Robert Maillart's Key Methods From the Salginatobel Bridge Design Process (1928)

Corentin Jean Dominique Fivet

This paper sheds light on some of the graphical methods used by Robert Maillart to design the Salginatobel Bridge, a three-hinged concrete structure spanning 90 meters. Built in 1929, this masterpiece has since received extensive recognition both for its s ...

Catalytic Enantiospecific [3+2] Annulation of Aminocyclopropanes with Ketones

Jérôme Waser, Fides Benfatti, Florian Patrick Marie Daniel De la Barre De Nanteuil

The first enantiospecific [3+2] annulation of D-A amino-cyclopropanes with ketones is reported herein (see scheme; Phth = phthaloyl). The reaction is catalyzed by 5 mol % of tin(IV) chloride at -78 °C and gives aminotetra-hydrofurans bearing a C5-quaternar ...

Chiral Phosphoric Acid-Catalyzed Enantioselective Three-Component Povarov Reaction Using Enecarbamates as Dienophiles: Highly Diastereo- and Enantioselective Synthesis of Substituted 4-Aminotetrahydroquinolines

Jieping Zhu

A chiral phosphoric acid (5)-catalyzed three-component Povarov reaction of aldehydes 2, anilines 3, and enecarbamates 4 afforded cis-4-amino-2-aryl(alkyl)-1,2,3,4-tetrahydroquinolines 1 in high yields with excellent diastereoselectivities (>95%) and almost ...

Cryptanalysis of e-mail protocols providing perfect forward secrecy

Recently, two e-mail protocols were proposed claiming to provide perfect secrecy. These protocols use authentication and (Diffie-Hellman) key-exchange techniques, and as such, other standard security criteria besides perfect forward secrecy include key-rep ...

Integrity (I) codes: Message Integrity Protection and Authentication over Insecure Channels

Jean-Pierre Hubaux, Mario Cagalj, Srdan Capkun

Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bit “1”, but not the contrary), we propose integrity codes (I-codes) for a radio co ...

Key Agreement in Peer-to-Peer Wireless Networks

Jean-Pierre Hubaux, Mario Cagalj, Srdan Capkun

We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the ``man-in-the-middle" attack if the two users ...
