A high-Q, tunable, bandpass filtered amplifier structure is proposed which is based on a novel Q enhancement technique in N-path filters. Using Fourier series analysis, frequency response of an N-path filter as well as the aliasing effects which are present in it are derived. Frequency translation of unwanted contents at higher frequencies to the center frequency of the bandpass filter is called h

Organisms are continually challenged by multiple threats in the environment, and such threats are seldom constant in either time or space. Therefore, organisms must maintain physiological, behavioural, morphological and life- history adaptations across environments to prevent reductions in fitness. Freshwater ecosystems are particularly variable environments, and so organisms inhabiting lakes and

Om platser verkligen är av betydelse, vilket ekonomiska geografer anser, då måste de vara som mest betydelsefulla för de människor vars liv utspelar sig på dessa platser, och upplever världen, materiellt kan kulturellt, genom den. När en kris och efterföljande osäkerheter drabbar en plats så påverkar detta främst människorna som kallar denna platsen för sitt hem. Ibland till den grad att en del avIf places indeed matter, as economic geographers believe, then it must matter most to the people who live their everyday lives in these places and experience the world materially and socially through it. When a crisis hits and uncertainty ensues, it affects people who call these places home the most. So much so, that some of them might be willing to stake a claim on its recovery, and development t

During 2020 archives and museums collected both personal memories and artifacts related to the corona outbreak. The aim was to document the unique situation and to save memories for the future. How can the experiences from this year be used in cooperation between academia and archives and museums?

This release brings together some of Ponce’s finest guitar works, carefully selected and sensitively performed by Bertrand Chavarría-Aldrete. The album opens with a Preludio written not long after Ponce arrived in Paris, characterised by modal and whole tone inflections that lend the piece an impressionistic quality. The release also includes the later set of Seis preludios cortos (‘Six short prel

RATIONALE AND OBJECTIVES: Thymic stromal lymphopoietin (TSLP), an epithelial upstream cytokine, initiates production of type-2 (T2) cytokines with eosinophilia and possibly airway hyperresponsiveness (AHR) in asthma.This study aimed to determine whether tezepelumab (a human monoclonal antibody targeting TSLP) decreases AHR and airway inflammation in patients with symptomatic asthma on maintenance

Acclaimed guitarist and artistic director of SMASH ensemble, Bertrand Chavarría-Aldrete, came up with the idea of starting an “archive” – at once a series of albums and a physical collection of repertoire – encompassing contemporary Spanish guitar music, simply because there wasn’t one. Born in Lyon, France, Bertrand has been resident in Spain for more than a decade, and believes fervently in the

I became acquainted with the music of Ramon Lazkano in 2001 through his guitar pieces. I was immediately fascinated with his ideas and his sound palette; somehow, I associated his music to a range of color between white and gray. His is a musical language where harmonics work as shadows and offer glimpses of a music that lives within a very personal and unique instrumental treatment.Later, togethe

Music by José Luis Campana, Iñaki Estrada, Manuel M. Ponce, Nicandro Tamez, Octavio López and Emmanuel Pautrot.

Plastic extension of Prélude 1923 by Manuel M. Ponce, ink and graphite drawings on cloth (2Mx2M & 2Mx1,60M)1 installation (stones and graphite and ink drawing on paper).

1 modular installation (6 plastic tubes).

Plastic-visual extension of Étude V pour guitare by Heitor Villa-Lobos.

Sempre morbida is a clay study installation and Plastic extension of Étude I by Heitor Villa-Lobos. The fingers are represented in a tablature for the left hand, a visual map of the iconic piece by the Brazilian composer.The piece was made during the Artistic Residency at Civitella Ranieri Foundation in Italy.

Nihonium (Nh, element 113) and flerovium (Fl, element 114) are the first superheavy elements in which the 7p shell is occupied. High volatility and inertness were predicted for Fl due to the strong relativistic stabilization of the closed 7p1/2 sub-shell, which originates from a large spin-orbit splitting between the 7p1/2 and 7p3/2 orbitals. One unpaired electron in the outermost 7p1/2 sub-shell

A γ-ray spectroscopic study of 212Po was performed at the Grand Accélérateur National d'Ions Lourds, using the inverse kinematics α-transfer reaction 12C(208Pb,212Po)8Be and the AGATA spectrometer. A careful analysis based on γγ coincidence relations allowed us to establish 14 new excited states in the energy range between 1.9 and 3.3 MeV. None of these states, however, can be considered as candid

The small time gaps of synchrotron radiation in conventional multi-bunch mode (100-500 MHz) or laser-based sources with high pulse rate (∼80 MHz) are prohibitive for time-of-flight (ToF) based photoelectron spectroscopy. Detectors with time resolution in the 100 ps range yield only 20-100 resolved time slices within the small time gap. Here we present two techniques of implementing efficient ToF r

ELI Beamlines is a rapidly progressing pillar of the pan-European Extreme Light Infrastructure (ELI) project focusing on the development and deployment of science driven by high-power lasers for user operations. This work reports the results of a commissioning run of a water-jet plasma X-ray source driven by the L1 Allegra laser, outlining the current capabilities and future potential of the syste
