New wine in old bottles: Quantum measurement - direct, indirect, weak - with some applications
In this, partly pedagogical review, I attempt to give a self-contained
overview of the basis of (non-relativistic) QM measurement theory expressed in
density matrix formalism. The focus is on applications to the theory of weak
measurement, as developed by Aharonov and Vaidman and their collaborators.
Their development of weak measurement combined with what they call
'post-selection' - judiciously choosing not only the initial state of a system
('pre-selection') but also its final state - has received much attention
recently. Not the least has it opened up new, fruitful experimental vistas,
like novel approaches to amplification. But the approach has also attached to
it some air of mystery. I will attempt to 'de-mystify' it by showing that
(almost) all results can be derived in a straight-forward way from conventional
QM. Among other things, I develop the formalism not only to first order but
also to second order in the weak interaction responsible for the measurement.
This also allows me to derive, more or less as a by-product, the master
equation for the density matrix of an open system in interaction with an
environment. One particular application I shall treat of the weak measurement
is the so called Leggett-Garg inequalities, a k a 'Bell inequalities in time'.
I also give an outline, even if rough, of some of the ingenious experiments
that the work by Aharonov, Vaidman and collaborators has inspired. If anything
is magic in the weak measurement + post-selection approach, it is the
interpretation of the so called weak value of an observable. Is it a bona fide
property of the system considered? I have no answer to this question; I shall
only exhibit the pros and cons of the proposed interpretation.Comment: 65 pages, 8 figure
Entropy-scaling search of massive biological data
Many datasets exhibit a well-defined structure that can be exploited to
design faster search tools, but it is not always clear when such acceleration
is possible. Here, we introduce a framework for similarity search based on
characterizing a dataset's entropy and fractal dimension. We prove that
searching scales in time with metric entropy (number of covering hyperspheres),
if the fractal dimension of the dataset is low, and scales in space with the
sum of metric entropy and information-theoretic entropy (randomness of the
data). Using these ideas, we present accelerated versions of standard tools,
with no loss in specificity and little loss in sensitivity, for use in three
domains---high-throughput drug screening (Ammolite, 150x speedup), metagenomics
(MICA, 3.5x speedup of DIAMOND [3,700x BLASTX]), and protein structure search
(esFragBag, 10x speedup of FragBag). Our framework can be used to achieve
"compressive omics," and the general theory can be readily applied to data
science problems outside of biology.Comment: Including supplement: 41 pages, 6 figures, 4 tables, 1 bo
Promising Developments in Bio-Based Products as Alternatives to Conventional Plastics to Enable Circular Economy in Ukraine
Transforming the plastic industry toward producing more sustainable alternatives than conventional plastics, as an essential enabler of the bio-based circular economy (CE), requires reinforcing initiatives to drive solutions from the lab to the market. In this regard, startups and ideation and innovation events can potentially play significant roles in consolidating efforts and investments by academia and industry to foster bio-based and biodegradable plastic-related developments. This study aimed to present the current trends and challenges of bioplastics and bio-based materials as sustainable alternatives for plastics. On this basis, having conducted a systematic literature review, the seminal research themes of the bio-based materials and bioplastics literature were unfolded and discussed. Then, the most recent developments of bio-based sustainable products in Ukraine, as alternatives to petroleum-based plastics, that have gained publicity through local startup programs and hackathons were presented. The findings shed light on the potential of the bio-based sector to facilitate the CE transition through (i) rendering innovative solutions most of which have been less noticed in academia before; (ii) enhancing academic debate and bridging the gap between developers, scholars, and practitioners within the plastic industry toward creating circularity across the supply chain; (iii) identifying the main challenges and future perspectives for further investigations in the future
Self-excited Oscillations of Charge-Spin Accumulation Due to Single-electron Tunneling
We theoretically study electronic transport through a layer of quantum dots
connecting two metallic leads. By the inclusion of an inductor in series with
the junction, we show that steady electronic transport in such a system may be
unstable with respect to temporal oscillations caused by an interplay between
the Coulomb blockade of tunneling and spin accumulation in the dots. When this
instability occurs, a new stable regime is reached, where the average spin and
charge in the dots oscillate periodically in time. The frequency of these
oscillations is typically of the order of 1GHz for realistic values of the
junction parameters

Identification of Molecular Fluorophore as a Component of Carbon Dots able to Induce Gelation in a Fluorescent Multivalent-Metal-Ion-Free Alginate Hydrogel
We introduce a simple approach to fabricate fluorescent multivalent metal ion-free alginate hydrogels, which can be produced using carbon dots accessible from natural sources (citric acid and L-cysteine). Molecular fluorophore 5-oxo-2,3-dihydro-5H-[1,3]-thiazolo[3,2-a] pyridine-3,7-dicarboxylic acid (TPDCA), which is formed during the synthesis of carbon dots, is identified as a key segment for the crosslinking of hydrogels. The crosslinking happens through dynamic complexation of carboxylic acid groups of TPDCA and alginate cages along with sodium ions. The TPDCA derived hydrogels are investigated regarding to their thermal, rheological and optical properties, and found to exhibit characteristic fluorescence of this aggregated molecular fluorophore. Moreover, gradient hydrogels with tunable mechanical and optical properties and controlled release are obtained upon immersion of the hydrogel reactors in solutions of divalent metal ions (Ca2+, Cu2+, and Ni2+) with a higher affinity to alginate. - 2019, The Author(s).This contribution was made possible by the NPRP award [8β878β1β172] from Qatar National Research Fund (a member of Qatar foundation), Qatar University grant QUCG-CAM-19/20-2 and by a grant from the Germany/ Hong Kong Joint Research Scheme sponsored by the Research Grants Council of Hong Kong and the Germany Academic Exchange Service of Germany (Reference No.: G-CityU103/16).

Oxygen Gradients and Structure of the Ciliate Assemblages in Floodplain Lake
This paper presents the results of studies on the structure of the ciliate population in a
freshwater lake. The classification of the ciliated communities based on the analysis of the distribution
of ciliate population density in the lake along the oxygen gradients, taking into account their oxygen
preferences, was proposed. It was shown that the distribution of ciliated protozoa in the space of
a reservoir is determined not by such spatial units as the water column, bottom, and periphytal,
but by the oxygen gradients. Four types of habitats with different oxygen regimes were distinguished:
With stably high oxygen concentration, stably low oxygen concentration, stably oxygen-free conditions,
and conditions with a high amplitude of diurnal oxygen variations. The location of these habitats in
the space of the lake and their seasonal changes were determined. On the basis of the quantitative
development of ciliate populations, zones of optima and tolerance ranges of some ciliate species
in the oxygen gradient were established. The oxygen preferences were established for the species
from four distinguished assemblages: Microoxyphilic, oxyphilic, euryoxyphilic, and anoxyphilic
(anaerobic). The presence or the absence of a certain type of assemblage in the reservoirs depends
solely on the parameters of the oxygen gradients. The diversity of the ciliated protozoa in water
bodies also depends on the stability and diversity of the oxygen gradients
