For a century and more, companies have ventured abroad only after establishing themselves at home," writes HBS professor Daniel J. Isenberg in this month's issue of Harvard Business Review. "Standing conventional theory on its head, start-ups now do business in

The pictures lack charm and often capture children at their worst yet still Tasmin Kelly thinks she'll buy.

Twelve police injured as violent protests sparked by fatal shooting of 15yearold continue across Greece.

It's the thought that's appreciated.

More than half of students are given wrong Alevel predictions with boys most likely to be marked down according to research.

Even with a rough season, two Cougars were honored for their performance by the conference. Senior middle blocker Rachel Dyer and junior right side hitter Kayla Walker both received All-MWC accolades.

Adults are quick to tell college students to 'enjoy life while you can,' but for an increasing number of college students, college life is filled with anxiety and stress.

When the sun shortens its visits because of daylight saving time and is shrouded in cloud cover for extended periods of time during the winter months, feeling down is somewhat normal. It's called Seasonal Affective Disorder

The enormous successes have been made by quantum algorithms during the lastdecade. In this paper, we combine the quantum game with the problem of dataclustering, and develop clustering algorithms based on it, in which data pointsin a dataset are considered

In ultra-peripheral relativistic heavy-ion collisions, a photon from theelectromagnetic field of one nucleus can fluctuate to a quark-antiquark pairand scatter from the other nucleus, emerging as a $\rho^0$. The $\rho^0$production occurs in two well-separated (median impact parameters of 20 and

Graphene is a monoatomic layer of graphite with Carbon atoms arranged in atwo dimensional honeycomb lattice configuration. It has been known for morethan sixty years that the electronic structure of graphene can be modelled bytwo-dimensional massless relativistic fermions. This property

We consider the vacuum-field pressure on boundaries of a metal slab in themiddle of a cavity with perfectly reflecting mirrors adopting the plasma modelfor the metal and paying special attention to the surface plasmon polaritoncontribution to the pressure. We demonstrate

Quantum mechanics and general relativity are completely compatible whenspacetime coordinate systems are eliminated from physics. Standard practiceattempts to remove coordinate influence through invariance because it isrecognized that coordinates are physically meaningless. But this isinsufficient. This paper investigates a transcoordinate physics

We demonstrate how the dynamical coarse-graining approach can besystematically extended to higher orders in the coupling between system andreservoir. Up to second order in the coupling constant we explicitly show thatdynamical coarse-graining unconditionally preserves positivity of the densitymatrix -- even

We develop a systematic approach to construct a new extended class ofcompletely solvable rational potentials. Second-order supersymmetric quantummechanics dictates the latter to be isospectral to some of the well-studiedquantum systems. Our method is illustrated with examples of generalizedP\"oschl-Teller and Scarf

We investigate the uncertainty associated with a joint quantum measurement oftwo components of spin of a spin-1/2 particle and quantify this in terms ofentropy. We consider two entropic quantities: the joint entropy and the sum ofthe marginal entropies, and obtain

In this paper I consider some logical and mathematical aspects of thediscussion of the identity and individuality of quantum entities. I shall pointout that for some aspects of the discussion, the logical basis cannot be putaside; on the contrary, it

We consider a linear quench from the paramagnetic to ferromagnetic phase inthe quantum Ising chain interacting with a static spin environment. Bothdecoherence from the environment and non-adiabaticity of the evolution near acritical point excite the system from the final ferromagnetic

We experimentally demonstrate a programmable single-qubit quantum gate. Thisdevice applies a unitary phase shift operation to a data qubit with the valueof the phase shift being fully determined by the state of a program qubit. Ourlinear optical implementation is based

We extend entangled coincidence (ghost) imaging to fluorescent samples. Giventhe entangled photon correlation, one photon of the pair carries information onwhere the other photon has been absorbed and has produced fluorescence in asample. Fluorescent molecules serve as ''detectors breaking'' the
