't Hooft's quantum determinism -- path integral viewpoint [PDF]

, 2005
We present a path integral formulation of 't Hooft's derivation of quantum from classical physics. Our approach is based on two concepts: Faddeev-Jackiw's treatment of constrained systems and Gozzi's path integral formulation of classical mechanics. This

Fibre bundle formulation of nonrelativistic quantum mechanics. III. Pictures and integrals of motion [PDF]

, 1998
We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one but it is in harmony with the modern trends in theoretical physics and potentially admits new ...

A Cathepsin B‐Triggered CO‐Releasing Molecule with a Non‐Toxic Metal Core for Targeted Tumor Delivery

Angewandte Chemie, EarlyView.
An iron‐based, enzyme‐triggered CO‐releasing molecule (ET‐CORM) is site‐specifically conjugated to the antibody trastuzumab. This novel ET‐CORM‐antibody conjugate releases carbon monoxide upon cleavage by the tumor‐associated protease cathepsin B. The construct enables selective intracellular CO delivery to HER2‐overexpressing and CatB‐expressing cells,

Interference, reduced action, and trajectories [PDF]

, 2006
Instead of investigating the interference between two stationary, rectilinear wave functions in a trajectory representation by examining the two rectilinear wave functions individually, we examine a dichromatic wave function that is synthesized from the ...

Triply Responsive Control of Ion Transport with an Artificial Channel Creates a Switchable AND to OR Logic Gate

Angewandte Chemie, EarlyView.
We report a triply responsive artificial ion channel, showing tuneable activity, and responsive to three distinct stimuli ‐ light, pH, and ligand – which we use to formulate an AND to OR switchable molecular logic gate. Abstract Ion channels are ubiquitous in Nature, performing complex and essential tasks in our bodies. Synthetic chemists have begun to

Chemoenzymatically Synthesized O‐Acetylated GD3 Gangliosides to Examine Viral Receptor Specificities in a Cellular Context

Angewandte Chemie, EarlyView.
7‐O‐, 9‐O‐, and 7,9‐di‐O‐acetylated GD3 gangliosides can be prepared by chemical assembly of a tetrasaccharide as α‐glycosyl fluoride that is coupled to sphingosine using a glycosynthase, followed by O‐acetyl editing by coronaviral hemagglutinin‐esterases (HEs).

Analysis of an experimental quantum logic gate by complementary classical operations [PDF]

, 2006
Quantum logic gates can perform calculations much more efficiently than their classical counterparts. However, the level of control needed to obtain a reliable quantum operation is correspondingly higher.

Design, Synthesis, and Structural Evolution of Pseudo‐Natural Product IDO1 Inhibitors and Degraders

Angewandte Chemie, EarlyView.
The combination of bicyclic monoterpene‐ and pyrrolidine‐alkaloid fragments yields novel pseudo‐natural products. Biological characterization revealed that these iDegs are inhibitors and degraders of indoleamine‐2,3‐dioxygenase. Abstract Terpenoid alkaloids are derived from the fusion of structurally diverse terpenoid‐ and alkaloid moieties.

Counterfactual Statements and Weak Measurements: an Experimental Proposal [PDF]

, 2001
A recent analysis [quant-ph/0104062] suggests that weak measurements can be used to give observational meaning to counterfactual reasoning in quantum physics.

Combined Error Correction Techniques for Quantum Computing Architectures [PDF]

, 2002
Proposals for quantum computing devices are many and varied. They each have unique noise processes that make none of them fully reliable at this time. There are several error correction/avoidance techniques which are valuable for reducing or eliminating ...
