description: Lower bounds are derived on the amplitude B of intergalactic magnetic fields (IGMFs) in the region between Galaxy and the blazar Mrk 421, from constraints on the delayed GeV pair-echo flux that are emitted by secondary e^-e^+ produced in γγinteractions between primary TeV gamma-rays and the cosmic infrared background. The distribution of galaxies mapped by the Sloan Digital Sky Survey shows that this region is dominated by a large intergalactic void. We utilize data from long-term, simultaneous GeV-TeV observations by the Fermi Large Area Telescope and the ARGO-YBJ experiment extending over 850 days. For an assumed value of B, we evaluate the daily GeV pair-echo flux expected from the TeV data, select the dates where this exceeds the Fermi 2-σsensitivity, compute the probability that this flux is excluded by the Fermi data for each date, and then combine the probabilities using the inverse normal method. Consequently, we exclude B < 10^{-20.5} G for a field coherence length of 1 kpc at 4- σlevel, as long as plasma instabilities are unimportant for cooling of the pair beam. This is much more significant than the 2-σbounds we obtained previously from observations of Mrk 501, by virtue of more extensive data from the ARGO-YBJ, as well as improved statistical analysis. Compared with most other studies of IGMF bounds, the evidence we present here for a non-zero IGMF is more robust as it does not rely on unproven assumptions on the primary TeV emission during unobserved periods.

M&M'S: Mix and Match Attacks on Schnorr-type Blind Signatures with Repetition.
Creators: name: Do, Khue

Publisher: name: CISPA
Year: 2024

description: Blind signatures allow the issuing of signatures on messages chosen by the user so that they ensure
 of the message against the signer. Moreover, a malicious user cannot output
 signatures while only finishing
 signing sessions. This notion, called
-
 unforgeability, comes in two flavors supporting either
 or
 sessions.

In this paper, we investigate the security of a class of blind signatures constructed from Sigma-protocols with small challenge space
 (i.e., polynomial in the security parameter), using
 repetitions of the protocol to decrease the chances of a cheating prover. This class of schemes includes, among others, the Schnorr blind signature scheme with bit challenges and the recently proposed isogeny-based scheme CSI-Otter (Crypto'23), as well as potential blind signatures designed from assumptions with the well-known Sigma-protocol for the graph-isomorphism problem (e.g., Lattice Isomorphism Problem).

For this class of blind signatures, we show a
-
 attack that breaks one-more unforgeability for any
 concurrent sessions in time
. Contrary to the ROS attack, ours is generic and does not require any particular algebraic structure. We also propose a computational trade-off, where, for any
, our attack works for

 in time

.

The consequences of our attack are as follows. Schemes in the investigated class of blind signatures should not be used concurrently without applying specific transformations to boost the security to support more signing sessions. Moreover, for the parameters proposed for CSI-Otter (
 and
), the scheme becomes forgeable after 128 concurrent signing sessions for the basic attack and with only eight sessions in our optimized attack. We also show that for those parameters, it is even possible to compute two signatures in around 10 minutes with just one signing session using the computation power of the Bitcoin network. Thus, we show that, for sequential security, the parameter
 must be at least doubled in the security parameter for any of the investigated schemes.
Spin-glass-like behavior in the spin turbulence of spinor Bose-Einstein condensates

description: We study numerically the spin turbulence in spin-1 ferromagnetic spinor Bose-Einstein condensates (BECs). Spin turbulence (ST) is characterized by a -7/3 power law in the spectrum of the spin-dependent interaction energy. The direction of the spin density vector is spatially disordered but temporally frozen in ST, showing some analogy with the spin glass state. Thus, we introduce the order parameter of spin glass into ST in spinor BECs. When ST develops through some instability, the order parameter grows with a -7/3 power law, thus succeeding in describing ST well.

description: Neoperla yanlii Li & Wang, sp. nov.
(Fig. 3)
 Male. Forewing length 15.4–16.2 mm. General body color brown. Distance between ocelli wider than diameter of the ocellus. Head mostly dark brown, with lateral margins and anterior portion of frons pale, M line brownish (Fig. 3 a); compound eyes black; antennae dark brown. Pronotum brown, anterior and posterior margins darker, with scattered rugosities (Fig. 3 a); wing membrane subhyaline, veins brown; legs mostly brownish. Abdomen yellow brown, hemiterga darker.
 Terminalia. Tergum 7 with posterior margin slightly produced into a subquadrate process, covered with many small sensilla basiconica (Fig. 3 b). Tergum 8 with tongue-like process, with small spines at distal margin (Fig. 3 b). Tergum 9 without sensilla patches but two cluster of long hairs. Hemitergal processes of tergum 10 strongly sclerotized and slightly bent ventrally at middle. Aedeagal tube plump and dorsal surface with a triangular sclerotized area, with a pair of spinous apical projections in ventral surface (Fig. 3 c). Aedeagal sac about 1.2X longer than tube and apical half curved dorsad, spinules occur on the entire dorsal surface and apical ventral surface, a cluster of ventral large spines and a triangular patch of dorsal spines present apically (Fig. 3 d).
 Female. Unknown.
 Type material. Holotype: male (HIST), China: Yunnan Province, Luchun County, Mt. Huanglianshan, 2011. V.7, light trap, Yan Li and Lihua Wang, 22.8906 N, 102.3037 E, 2 males (CAU & HNHM), same data as holotype.
 Etymology. The patronym honors the collector of the holotype.
 Distribution. China (Yunnan Province).
 Diagnosis and remarks. The new species is similar to two Vietnamese species, N. nebulosa Stark and Sivec, 2008 and N. spinaloba Stark and Sivec, 2008. It shares similar head pattern and terminalia with N. nebulosa (figs. 51–55, Stark and Sivec 2008), but may be easily separated from N. nebulosa by having the aedeagal sac longer than tube (fig. 3d). The new species has very similar aedeagal structure to N. spinaloba Stark and Sivec, 2008 (figs. 64, Stark and Sivec 2008), but differ in the head pattern, outlines and details of two patches of large apical spines of aedeagal sac (comparing to fig. 3d).

description: The seesaw mechanism can be generalized to a Type-III variant and a quintuplet variant. We present two models that provide analogous generalizations of the inverse seesaw mechanism. The first model employs a fermion triplet F ~ (1,3,0) and requires no additional multiplets or parameters relative to the standard inverse seesaw. We argue that, from a bottom-up perspective, there appears to be no particular reason to preference the usual scenario over this variant. The second model employs a fermion quintuplet F ~ (1,5,0) and requires an additional scalar S ~ (1,4,1). We also show that minimal inverse seesaws with even larger fermionic representations are not expected to realize naturally small neutrino masses.

Μεγάλο πλήθος τεκμηρίων: εγγράφων –δακτυλογραφημένων αντιγράφων στην πλειονότητά τους -, σχεδίων, φωτογραφικού και χαρτογραφικού υλικού- απαρτίζουν το Fonds Michel Pacha (102 APOM) με ταξινομικούς αριθμούς 1 έως 618. Η ταξινόμηση και καταλογογράφηση του αρχείου εκπονήθηκε από τον François Pourcelet (Pourcelet 2001).
Ο πέτρινος φάρος του Αγίου Ιωάννη ανεγέρθηκε σε δυο φάσεις , η πρώτη στα τέλη του 19ου αιώνα από την γαλλική εταιρία την AdministrationGeneraledesPharesdel’ EmpireOttoman, και η δεύτερη στις αρχές του 20ου αιώνα στην εποχή της ανασυγκρότησης του ελληνικού φαρικού δικτύου. Αξιόλογο και ιδιότυπο δείγμα φαρικού κτίσματος της περιόδου ενταγμένο στο μοναδικό τοπίου της περιοχής.
Σήμερα ο φάρος δεν χρησιμοποιείται, η κατάσταση διατήρησης του είναι ιδιαίτερα κρίσιμη από δομική άποψη, δεδομένου ότι μέρος του κτιρίου έχει καταρρεύσει και στο υπόλοιπο εντοπίζονται σοβαρά συμπτώματα παθολογίας λόγω της εγκατάλειψής του αλλά και λόγω των ακραίων περιβαλλοντικών συνθηκών στις οποίες μόνιμα εκτίθεται.
Η ανάγκη για αποκατάστασή του σύμφωνα με τις σύγχρονες  αρχές αποκατάστασης ιστορική τεκμηρίωση του και η ύπαρξη σχεδίων οδηγών, μας δίνει σήμερα την δυνατότητα να γίνουν οι απαραίτητες συμπληρώσεις, ώστε να αποδοθεί στο μνημείο  η πολιτιστική του διάσταση στο σύνολό του, και παράλληλα να  αποκατασταθεί ο συσχετισμός του με την τοπική κοινωνία και ιστορία.
Οι βασικοί στόχοι της μελέτης είναι η αποκατάσταση του ιστορικού κελύφους του φάρου και η ανάδειξη των ιδιαίτερων μορφολογικών και τυπολογικών χαρακτηριστικών του, η νέα χρήση του ως εκθεσιακού χώρου και η επαναλειτουργία του φωτιστικού μηχανήματος στον πύργο του φάρου. Παράλληλα η δημιουργία ασφαλών προσβάσεων, μεσόγεια και παράκτια  και η αποκατάσταση σχέσης του Φάρου με την γύρω περιοχή , η οργάνωση του ευρύτερου περιβάλλοντος χώρου του φάρου με τη διαμόρφωση χώρων στάσεων πανοράματος και ενημέρωσης των επισκεπτών.

description: From microscopic fluid clusters to macroscopic droplets, the structure of fluids is governed by the Van der Waals force, a force that acts between polarizable objects. In this Letter, we derive a general theory that describes the non-equilibrium counterpart to the Van der Waals force, which emerges in spatially coherently fluctuating electromagnetic fields. We describe the formation of a novel and complex hierarchy of self-organized morphologies in magnetic and dielectric colloid systems. Most striking among these morphologies are dipolar foams - colloidal superstructures that swell against gravity and display a high sensitivity to the applied field. We discuss the dominance of many body forces and derive the equation of state for a material formed by the coherent Van der Waals force. Our theory is applied to recent experiments in paramagnetic colloidal systems and a new experiment is suggested to test the theory.

Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 inverse femtobarns (5.1 inverse femtobarns) collected in pp collisions at the center-of-mass energy of 7 TeV (8 TeV). Events are considered where the top-quark pair decays to either one lepton+jets (t tbar to ell nu q q' b bbar) or dileptons (t tbar to ell(+) nu ell(-) nu b bbar), ell being an electron or a muon. The search is optimized for the decay mode H to b bbar. The largest background to the t tbar H signal is top-quark pair production with additional jets. Artificial neural networks are used to discriminate between signal and background events. Combining the results from the 7 TeV and 8 TeV samples, the observed (expected) limit on the cross section for Higgs boson production in association with top-quark pairs for a Higgs boson mass of 125 GeV is 5.8 (5.2) times the standard model expectation.

description: Η παρούσα εργασία έχει ως αντικείμενο την πρόταση αποκατάστασης του φάρου του Αγίου Ιωάννη ή Αφορεσμένου που βρίσκεται στο ΒΔ άκρο του κόλπου του Μεραμπέλου στο ανατολικό άκρο της νήσου Κρήτης. Πρόκειται για φαρικό συγκρότημα το οποίο ανεγέρθηκε από τη Γαλλική Εταιρεία Φάρων στα τέλη του 19ου αιώνα κατά τη διάρκεια της Οθωμανικής κυριαρχίας στην Κρήτη και συμπληρώθηκε και επεκτάθηκε στη συνέχεια στις αρχές του 20ου αιώνα την εποχή της ανασυγκρότησης του Ελληνικού φαρικού δικτύου. Το κτίριο ακολουθεί την τυποποίηση των υπόλοιπων φαρικών συγκροτημάτων της εποχής εκείνης στην Κρήτη ενώ αποτελεί το μοναδικό δείγμα αρχιτεκτονικά που συνδυάζει δύο διαφορετικές φάσεις κατασκευής. Αρχικά ο φάρος λειτουργούσε με κλεισιάδα ενώ στη Β  φάση επί Ελληνικής κυριαρχίας κατασκευάστηκε πύργος πάνω στον οποίο τοποθετήθηκε φωτιστικό μηχάνημα. Ο φάρος λειτούργησε επανδρωμένος ως το δεύτερο παγκόσμιο πόλεμο. Σήμερα ο φάρος λειτουργεί ως αυτόματος φάρος εκτός του φαρικού συγκροτήματος σε θέση λίγο ψηλότερα. Φέρει σημαντικές βλάβες κυρίως λόγω εγκατάλειψης και κακής συντήρησης ενώ ο πύργος έχει απολέσει το φωτιστικό του μηχάνημα.
Για τη σύνταξη της παρούσας εργασίας πραγματοποιήθηκε ιστορική τεκμηρίωση των οικοδομικών φάσεων του μνημείου, αρχιτεκτονική αποτύπωση, ανάλυση της παθολογίας του κτιρίου, προσομοίωση του υλικού δόμησής του και προσομοίωση του κελύφους της προγενέστερης οικοδομικής του φάσης, όπως προέκυψε από την ιστορική τεκμηρίωση, και της πρότασης αποκατάστασης στο πρόγραμμα Marc-Mentat. Η παραπάνω ανάλυση κατέληξε στη σύνταξη των προτεινόμενων μέτρων για την ενίσχυση-αποκατάσταση και επανάχρησή του ως μουσείο.

description: It is known that more than 50 species use the Earth's magnetic field for orientation and navigation. Intensive studies particularly behavior experiments with birds, provide support for a chemical compass based on magnetically sensitive free radical reactions as a source of this sense. However, the fundamental question of how quantum coherence plays an essential role in such a chemical compass model of avian magnetoreception yet remains controversial. Here, we show that the essence of the chemical compass model can be understood in analogy to a quantum interferometer exploiting global quantum coherence rather than any subsystem coherence. Within the framework of quantum metrology, we quantify global quantum coherence and correlate it with the function of chemical magnetoreception. Our results allow us to understand and predict how various factors can affect the performance of a chemical compass from the unique perspective of quantum coherence assisted metrology. This represents a crucial step to affirm a direct connection between quantum coherence and the function of a chemical compass.

description: Η συγκεκριμένη διπλωματική εργασία εκπονείται στα πλαίσια του μεταπτυχιακού «Χώρος και Σχεδιασμός» του Πολυτεχνείου Κρήτης και πραγματεύεται την ανάπτυξη σχεδίων βιώσιμης κινητικότητας του δήμου Χανίων. Η επιλογή συγκρότησης συγκεκριμένα του σχεδίου ΣΒΑΚ δεν ήταν τυχαία και αιτιολογείται διότι, διαθέτει αρκετά πλεονεκτήματα με κυριότερο την βελτίωση του βιοτικού επιπέδου, θέτοντας ως προτεραιότητα του σχεδιασμού τον άνθρωπο έναντι του αυτοκινήτου. Αυτό αποτελεί την κύρια αιτία που το καθιστά ποιοτικότερο από μία απλή κυκλοφοριακή μελέτη. Παράλληλα όμως βελτιώνει και την εικόνα ολόκληρης της πόλης, άρα και της ανταγωνιστικότητάς της ως προς χρηματοδοτήσεις, που εν καιρώ κρίσης δεν θεωρείται αμελητέο ζητούμενο.
Όσον αφορά τη περιοχή μελέτης επιλέχθηκε, αρχικά, εξαιτίας του γεγονότος ότι δεν έχει εκπονηθεί ακόμα κάποιο σχέδιο ΣΒΑΚ για εκείνη και έπειτα διότι η κυκλοφοριακή της οργάνωση χρήζει βελτίωσης. Ενδεικτικά, υστερεί στην ύπαρξη επαρκών οργανωμένων χώρων στάθμευσης, στην ύπαρξη δικτύου ποδηλάτων και πεζών, ενώ αντιμετωπίζει και έντονα προβλήματα κορεσμού σε αρκετούς από τους κεντρικότερους οδικούς της άξονες. Το πρόβλημα αυτό διογκώνεται τους θερινούς μήνες λόγω της εποχικότητας. Ταυτόχρονα, όμως, διαθέτει και ορισμένες προοπτικές για αναβάθμιση του χώρου, καθώς και ένα ισχυρό πεζοδρομημένο ιστορικό κέντρο.
Στο πρώτο κεφάλαιο γίνεται μία σύντομη αναφορά στο κυκλοφοριακό πρόβλημα των σύγχρονων πόλεων, καθώς και μία προσπάθεια εννοιολογικής προσέγγισης του όρου της “βιώσιμης κινητικότητας”, που προκύπτει ως λύση στο κυκλοφορικό. Έπειτα, μελετώνται τα χαρακτηριστικά και τα στάδια εκπόνησης ενός Σχεδίου Βιώσιμης Κινητικότητας ή αλλιώς ΣΒΑΚ, έτσι ώστε να μπορέσουν να γίνουν πλήρως κατανοητά η σπουδαιότητα και ο ρόλος του, με απώτερο σκοπό την εκπόνηση ενός αντίστοιχου σχεδίου για την περιοχή μελέτης.
Στο δεύτερο κεφάλαιο, αρχικά εξετάζεται εν συντομία η ιστορική εξέλιξη της περιοχής μελέτης, καθώς και οι ιστορικές μεταβολές που έχουν λάβει χώρα τα τελευταία χρόνια και έπειτα τα σημερινά κυκλοφοριακά προβλήματα και οι παθογένειες του οδικού δικτύου της. Στη συνέχεια αναλύονται τα χωρικά και πολεοδομικά στοιχεία που συλλέχθηκαν, με κυριότερο εξ αυτών τις χρήσεις γης. Σκοπό αυτού του κεφαλαίου αποτελεί η εξαγωγή συμπερασμάτων όχι μόνο για το πλήθος ή την ένταση των κυκλοφοριακών προβλημάτων, αλλά και τις ενδεχόμενες αιτίες εμφάνισης τους ή τις τάσεις εξέλιξης τους.
Στο τρίτο και τελευταίο κεφάλαιο, αφού έχουν διατυπωθεί συμπεράσματα για τα προβλήματα της περιοχής και τις διαδικασίες εκείνες που τα διογκώνουν, θα προκύψουν οι προτάσεις για τη βελτίωση και αναβάθμιση του οδικού δικτύου και των χώρων κίνησης της πόλης των Χανίων, που ταυτόχρονα θα συγκροτήσουν και το σχέδιο βιώσιμης ανάπτυξης του Δήμου.

description: We study the possibility of producing and detecting continuous variable cluster states in an optical set-up in an extremely compact fashion. This method is based on a multi-pixel homodyne detection system recently demonstrated experimentally, which includes classical data post-processing. It allows to incorporate the linear optics network, usually employed in standard experiments for the production of cluster states, in the stage of the measurement. After giving an example of cluster state generation by this method, we further study how this procedure can be generalized to perform gaussian quantum computation.

description: Starting from a classical-mechanics stochastic model encoded in a Langevin equation, we derive the natural diffusion equation associated with three classes of multiscale spacetimes (with weighted, ordinary, and "q-Poincaré" symmetries). As a consistency check, the same result is obtained by inspecting the propagation of a quantum-mechanical particle in a disordered environment. The solution of the diffusion equation displays a time-dependent diffusion coefficient and represents a probabilistic process, classified according to the statistics of the noise in the Langevin equation. We thus illustrate, also with pictorial aids, how spacetime geometries can be more completely catalogued not only through their Hausdorff and spectral dimension, but also by a stochastic process. The spectral dimension of multifractional spacetimes is then computed and compared with what was found in previous studies, where a diffusion equation with some open issues was assumed rather than derived. These issues are here discussed and solved, and they point towards the model with q-Poincaré symmetries.

description: The scaling of island and monomer density, capture zone distributions (CZDs), and island size distributions (ISDs) in reversible submonolayer growth was studied using the Clarke-Vvedensky model. An approach based on rate-equation results for irreversible aggregation (IA) models is extended to predict several scaling regimes in square and triangular lattices, in agreement with simulation results. Consistently with previous works, a regime I with fractal islands is observed at low temperatures, corresponding to IA with critical island size i=1, and a crossover to a second regime appears as the temperature is increased to εR^{2/3} ~ 1, where εis the single bond detachment probability and R is the diffusion-to-deposition ratio. In the square (triangular) lattice, a regime with scaling similar to IA with i=3 (i=2) is observed after that crossover. In the triangular lattice, a subsequent crossover to an IA regime with i=3 is observed, which is explained by the recurrence properties of random walks in two dimensional lattices, which is beyond the mean-field approaches. At high temperatures, a crossover to a fully reversible regime is observed, characterized by a large density of small islands, a small density of very large islands, and total island and monomer densities increasing with temperature, in contrast to IA models. CZDs and ISDs with Gaussian right tails appear in all regimes for R ~ 10^7 or larger, including the fully reversible regime, where the CZDs are bimodal. This shows that the Pimpinelli-Einstein (PE) approach for IA explains the main mechanisms for the large islands to compete for free adatom aggregation in the reversible model, and may be the reason for its successful application to a variety of materials and growth conditions.

description: We present a study of the highly nonlinear optical excitation of noble gases in tapered hollow waveguides using few-femtosecond laser pulses. The local plasmonic field enhancement induces the generation of a nanometric plasma, resulting in incoherent extreme-ultraviolet fluorescence from optical transitions of neutral and ionized xenon, argon, and neon. Despite sufficient intensity in the waveguide, high-order harmonic generation is not observed. The fluorescent emission exhibits a strong bistability manifest as an intensity hysteresis, giving strong indications for multistep collisional excitations.

description: The interplay between superconductivity and Eu$^{2+}$ magnetic ordering in Eu(Fe$_{1-x}$Ir$_{x}$)$_{2}$As$_{2}$ is studied by means of electrical transport and magnetic measurements. For the critically doped sample Eu(Fe$_{0.86}$Ir$_{0.14}$)$_{2}$As$_{2}$, we witnessed two distinct transitions : a superconducting transition below 22.6 K which is followed by a resistivity reentrance caused by the ordering of the Eu$^{2+}$ moments. Further, the low field magnetization measurements show a prominent diamagnetic signal due to superconductivity which is remarkable in presence of a large moment magnetically ordered system. The electronic structure for a 12.5% Ir doped EuFe$_{1.75}$Ir$_{0.25}$As$_{2}$ is investigated along with the parent compound EuFe$_{2}$As$_{2}$. As compared to EuFe$_{2}$As$_{2}$, the doped compound has effectively lower value of density of states throughout the energy scale with more extended bandwidth and stronger hybridization involving Ir. Shifting of Fermi energy and change in band filling in EuFe$_{1.75}$Ir$_{0.25}$As$_{2}$ with respect to the pure compound indicate electron doping in the system.

description: Uncertainty relations are a distinctive characteristic of quantum theory that impose intrinsic limitations on the precision with which physical properties can be simultaneously determined. The modern work on uncertainty relations employs \emph{entropic measures} to quantify the lack of knowledge associated with measuring non-commuting observables. However, there is no fundamental reason for using entropies as quantifiers; any functional relation that characterizes the uncertainty of the measurement outcomes defines an uncertainty relation. Starting from a very reasonable assumption of invariance under mere relabelling of the measurement outcomes, we show that Schur-concave functions are the most general uncertainty quantifiers. We then discover a fine-grained uncertainty relation that is given in terms of the majorization order between two probability vectors, \textcolor{black}{significantly extending a majorization-based uncertainty relation first introduced in [M. H. Partovi, Phys. Rev. A \textbf{84}, 052117 (2011)].} Such a vector-type uncertainty relation generates an infinite family of distinct scalar uncertainty relations via the application of arbitrary uncertainty quantifiers. Our relation is therefore universal and captures the essence of uncertainty in quantum theory.

Splashing onset in dense suspension droplets

description: We investigate the impact of droplets of dense suspensions onto a solid substrate. We show that a global hydrodynamic balance is unable to predict the splash onset and propose to replace it by an energy balance at the level of the particles in the suspension. We experimentally verify that the resulting, particle-based Weber number gives a reliable, particle size and density dependent splash onset criterion. We further show that the same argument also explains why in bimodal systems smaller particles are more likely to escape than larger ones.

description: The monolayer transition metal dichalcogenides have recently attracted much attention owing to their potential in valleytronics, flexible and low-power electronics and optoelectronic devices. Recent reports have demonstrated the growth of large-size 2-dimensional MoS2 layers by the sulfurization of molybdenum oxides. However, the growth of transition metal selenide monolayer has still been a challenge. Here we report that the introduction of hydrogen in the reaction chamber helps to activate the selenization of WO3, where large-size WSe2 monolayer flakes or thin films can be successfully grown.

description: Assessment of growth and production of metabolites of interest from a given microalgae on a laboratory scale is crucial to evaluate its potential applicability on larger scales into the biotechnology sector. Our work within the H2020 NewTechAqua project focuses on fatty acid production for use of microalgae as aquafeed in the aquaculture industry. Growth studies of microalgae comprise the estimation of cell density over time, for which several methods have been described in the literature. While indirect methods are undoubtedly less time-consuming, their relevance needs to be evaluated case by case for the species and the experimental conditions used. Our study focused on the benthic diatom Nitzschia palea, a species of interest for biotechnology (Abdel-Hamid et al., 2013). Three native strains of N. palea from the Canaries were cultured for 26 days in triplicate flasks under the same culture conditions. Growth was monitored using cell counting as direct method, and optical density (OD) and basal fluorescence (Fo) as indirect methods. The three strains showed their maximum growth rates between days 4 and 7 (0.21 – 0.29 day-1), and entered the stationary phase at day 17. The relevance of OD and Fo was demonstrated during the exponential phase only (days 4 – 17), as they both positively correlated with cell density in a linear regression model (R2 > 0.89, n = 45). Preliminary results on the fatty acid (FA) composition indicated that the major FAs produced by N. palea were palmitic acid (18 – 41 %) and palmitoleic acid (12 – 25 %), in accordance with a previous study (Touliabah et al., 2020). As for the ω-3 FAs, DHA was poorly produced (≤ 3%), while EPA constituted a major FA for two of the strains (21% and 13%). This study showed that OD and Fo were suitable alternatives to cell counting for cell density estimation, at least during the exponential phase of growth, allowing faster execution of the daily laboratory work. More accurate studies on the fatty acid production should be developed in the future to have a more comprehensive view of the biotechnological value of these strains.
