Intensity modulation and direct detection quantum key distribution based on quantum noise by Takuya Ikuta, Kyo Inoue

“…Two slightly intensity-modulated pulses are sent from a transmitter, and a receiver determines key bits from the directly detected intensity. We analyzed the system performance for two typical eavesdropping methods, a beam splitting attack and an intercept-resend attack, with an assumption that the transmitting and receiving devices are fully trusted. …”

Scalar quantization with random thresholds by Goyal, Vivek K.

“…The distortion is at most six times that of an optimal (deterministically-designed) quantizer, and for a large number of levels the output entropy is reduced by approximately (1-γ)/(ln 2) bits, where γ is the Euler-Mascheroni constant. This shows that the high-rate asymptotic distortion of these quantizers in an entropy-constrained context is worse than the optimal quantizer by at most a factor of 6e[superscript -2(1-γ)] ≈ 2.58.…”

Quantum Gravity Constraints on Inflation by Conlon, J

“…We give two prescriptions for determining the inflationary entropy, based on either `bits per unit area' or entanglement entropy. The existence of transPlanckian flat directions, necessary for large tensor modes in the CMB, correlates with an inflationary entropy greater than that allowed by de Sitter space. …”

Chemical, microbial and sensory properties of a chestnut and milk ice cream with improved healthy characteristics by Luis A. Espinoza, Laura Purriños, Juan A. Centeno, Javier Carballo

“…With the aim of revalorization of two productions of economic relevance (milk and chestnuts), a novel ice cream was formulated incorporating milk, chestnut flour and chestnut bits. Using the best sensory valued formula as a basis, eight ice cream formulations were elaborated replacing the ingredients normally used (milk fat, sucrose and carboxymethylcellulose) by healthier ones (olive oil, erythritol + steviol glycosides, and tara (Caesalpinia spinosa) gum, respectively). …”
