Heart failure is one of the most common reasons for death in the modern society. As the field of tissue engineering is evolving, cardiac patches as treatment for suffering patients holds future promise. However, methods for efficient purification of cardiomyocytes from biopsies are lacking, hindering the development of such solutions. Here a novel method for separation of cardiomyocytes in a micro
We report and compare highly resolved, simultaneously recorded absorption and CD spectra of active Photosystem II (PSII) samples in the range 440-750 nm. From an appropriately scaled comparison of spinach membrane fragment (BBY) and PSII core spectra, we show that key features of the core spectrum are quantitatively represented in the BBY data. PSII from the cyanobacterium Synechocystis 6803 displ
A recently formulated theory of high-order harmonic generation by low-frequency laser fields [Anne L'Huillier et al., Phys. Rev. A 48, R3433 (1993)] allows us to study the phase of the induced atomic dipole moment. We show that this phase exhibits a piecewise-linear dependence on the laser intensity. This dependence can be interpreted in quasiclassical terms, and is related to the action acquired
The first-order electroweak phase transition in the early universe could occur in multiple steps leading to specific multi-peaked signatures in the primordial gravitational wave (GW) spectrum. We argue that these signatures are generic phenomena in multi-scalar extensions of the Standard Model. In a simple example of such an extension, we have studied the emergence of reoccuring and nested vacuum
We propose to use quantum information notions to characterize thermally induced melting of nonperturbative bound states at high temperatures. We apply tensor networks to investigate this idea in static and dynamical settings within the Ising quantum field theory, where bound states are confined fermion pairs - mesons. An equilibrium signature of meson melting is identified in the temperature depen
Two movable-bed physical model experiments of breach growth in a sandy barrier were conducted in a 3.3-m wide, 64-m long flume with a wave generator capable of generating 0.5 m waves. Breaching was initiated both without waves (Case BR1) and with waves (Case BR2) in separate tests by maintaining a head across the barrier. Breach channel deepening was controlled by the head difference across the ba
Entanglement has the ability to enhance the transmission of classical information over a quantum channel. However, fully harvesting this advantage typically requires complex entangling measurements, which are challenging to implement and scale with the system's size. In this Letter, we consider a natural quantum information primitive known as a random access code in which the message to be communi
The experimental realization of quantum molecular spectroscopy with entangled photons remains challenging owing to the low signal-to-noise ratio resulting from the use of low-flux entangled photons. High-flux entangled photons via intense entangled beams can be used to improve the signal-to-noise ratio, but the presence of unentangled photons contaminates the quantum signal stemming from entangled
The quantum prepare-and-measure scenario has been studied under various physical assumptions on the emitted states. Here, we first discuss how different assumptions are conceptually and formally related. We then identify one that can serve as a relaxation of all others, corresponding to a limitation on the one-shot accessible information of the state ensemble. This motivates us to study the optima
The Division of Industrial Electrical Engineering and Automation (IEA) offers a number of courses in industrial electrical engineering and automation both in Lund for several Engineering programmes and at Campus Helsingborg for the programme in Electrical Engineering and Automation. IEA focuses on applications in Energy and Environment with courses and research in renewable energy generation (wind

Understanding of the environmental and climate processes Research at the department of Physical Geography and Ecosystem Science is mainly focused on interdisciplinary studies of how climate and environmental changes affect the function and composition of terrestrial ecosystems. The goal is to increase understanding of the processes that take place in the exchange between the biosphere and atmosphe

Position and direction estimation is useful for numerous engineering applications for commercial, scientific, and military purposes. Technology that fuses observations of signals broadcast by Global Navigational Satellite Systems (GNSS) with inertial measurements is standard for electronic devices, but this requires at least a periodically unobstructed view of the sky to perform reliably. This has
Neutron crystallography is a powerful method to determine the positions of H atoms in macromolecular structures. However, it is sometimes hard to judge what would constitute a chemically reasonable model, and the geometry of H atoms depends more on the surroundings (for example the formation of hydrogen bonds) than heavy atoms, so that the empirical geometry information for the H atoms used to sup
We describe development and application of the CH3 photo-fragmentation laser-induced fluorescence (PF-LIF) diagnostic whereby CH is created and then detected. Specifically, we employed sum-frequency generation to produce 5th-harmonic output from a Nd:YAG laser (λ = 212.8 nm) for photolyzing CH3. The residual 2nd-harmonic beam was then used to pump a dye laser, the output of which was frequency-dou
The study of relationship between well-being and living space is an actively expanding field across psychology, anthropology, history, archeology, architecture, interior design and philosophy. The human condition in relation to environmental factors has several scientific conclusions in terms of physical effect and mental health – green foliage, sunlight, certain proportions and ergonomic conditio
