Dissipative Kerr solitons formed in high-Q optical microresonators provide a route to miniaturized optical frequency combs that can revolutionize precision measurements, spectroscopy, sensing, and communication. In the past decade, a myriad of integrated material platforms have been extensively studied and developed to create photonic-chip-based soliton combs. However, the photo-thermal effect in integrated optical microresonators has been a major issue preventing simple and reliable soliton generation. Several sophisticated techniques to circumvent the photo-thermal effect have been developed. In addition, instead of the single-soliton state, emerging applications in microwave photonics and frequency metrology prefer multi-soliton states. Here, we demonstrate an approach to manage the photo-thermal effect and facilitate soliton generation. The approach is based on a single phase-modulated pump, where the generated blue-detuned sideband synergizes with the carrier and thermally stabilizes the microresonator. We apply this technique and demonstrate deterministic soliton generation of 19.97 GHz repetition rate in an integrated silicon nitride microresonator. Furthermore, we develop a program to automatically address to the target N-soliton state, in addition to the single-soliton state, with a near 100% success rate and as short as 10 s time consumption. Our method is valuable for soliton generation in essentially any platform, even with strong photo-thermal effects, and can promote wider applications of soliton frequency comb systems for microwave photonics, telecommunications, and frequency metrology.
First principles study of two-dimensional high-temperature antiferromagnetic semiconductor MoICl2 under strain effect
Authors: Lan Xinqi , Gao Yan , Ge Yanfeng , Wan Wenhui , Liu Yong 
Published: December 2023

Two-dimensional antiferromagnetic materials with room-temperature magnetism are ideal materials for antiferromagnetic spintronic devices. In this paper, antiferromagnetic monolayer MoICl2 based on first-principles calculations is reported. We predict that monolayer MoICl2 is an antiferromagnetic semiconductor with an indirect bandgap. In the study of strain-induced effects on the system, the electronic structure, bandgap, and magnetic anisotropy energy of monolayer MoICl2 undergo significant changes. However, its magnetic ground state remains unaffected and continues to exhibit antiferromagnetic behavior. Particularly, we predict that the Néel temperature (TN) of monolayer MoICl2 is 53 K and that TN can be further increased to 380 K at a biaxial compressive strain of 6%. The results indicate that monolayer MoICl2 can serve as a potential candidate material for spintronics applications.
The effect of test format on productive recall of derivatives
Authors: Iwaizumi Emi , Webb Stuart 
Published: December 2023

Abstract
This study investigated the extent to which two recall test formats – contextualized and decontextualized tests –
affected productive recall of derivatives, and how the effects of token frequencies of derivatives and L2 receptive vocabulary
knowledge on recalling derivatives was moderated by test format. Mixed effects logistic regression models examined the derivatives
elicited from L1 (n = 21) and L2 English speakers’ (n = 107) on the two recall tests. Results
indicated that contextual cues significantly facilitated recalling derivatives, while such facilitative effects were larger for
native speakers and L2 learners with greater vocabulary knowledge. Furthermore, token frequency affected the responses on the
decontextualized test to a greater degree compared to the contextualized test. Results suggest that test format influences
test-takers’ ability to recall knowledge to produce derivatives.
End-weight at its most dynamic
Authors: Schlüter Julia , Rohdenburg Günter 
Published: December 2023

Abstract
This contribution supports and extends the principle of end-weight, first formulated by Quirk et al. (1972) to describe the tendency of heavy constituents to appear late in a sentence.
Developing this principle further, we argue that it favours the addition of (functionally non-neutral) morphological markers to
sentence-final constituents, which are typically characterized by prosodic prominence. The markers we study are undergoing
diachronic establishment or loss and are thus temporarily variable. They represent rather diverse categories in different West
Germanic languages and varieties (English, Northern Low German, Frisian) and have been gathered from different periods. Examples
include inflectional endings of nouns, adjectives, finite verbs and infinitives, pro-form uses of possessives and the adjective
other, prepositional choices, the a-prefix and periphrastic doon ‘do’. We
suggest that end-weight is scalar, with absolute sentence-final position producing the strongest effects.
Zur Eindeutschung slawischer Ortsnamen in Bayern
Authors: Bichlmeier Harald 
Published: December 2023

AbstractThe way in which Slavic names in Bavaria have been transmitted into Old High German has been well researched already, but open questions remain. It is possible to date the loan processes when the names contain sounds with diagnostic value or show datable sound changes, such as the metathesis of liquids or the rounding of Proto-Slavic *ato Common Slavic *oor when Slavic *bis substituted by OHG *v >f. The integration of Slavic names into OHG started before 800 and came to an end around 1100. The way in which Slavic *ěwas loaned also might play a role in dating these processes, but the situation remains unclear so far: Mostly it appears as OHGe,ē, but in a few cases there is a resulting sound containing /i/. This sound may have come into existence either by an early integration of Slavic *ěas OHG *ē2or when a younger Sorbian raising of *ěto somei-diphthong had already taken place.
Runic fragments from the Svingerud grave field in Norway
Authors: Zilmer Kristel , Vasshus Krister S.K. 
Published: December 2023

AbstractIn 2021–2023, several rune-inscribed sandstone fragments were discovered by archaeologists of the Museum of Cultural History, University of Oslo, at a Roman Iron Age grave field by the Svingerud road at Hole in eastern Norway. Several of these fragments fit together as parts of one larger sandstone slab. The main fragment with multiple inscriptions was unearthed in a flat grave (cremation) in November 2021. Radiocarbon dating of the organic material dated the burial to before 300 CE (Solheim et al., forthcoming). This article provides a detailed runological and linguistic account of the inscribed fragments, as of July 2023. The focus is on the main finds, while the work on numerous small fragments is ongoing. This find may shed new light on the features and functions of early runic writing.
Stativity and inchoativity
Authors: Mangialavori Rasia Mª Eugenia , Ausensi Josep 
Published: December 2023

AbstractStates, long considered a homogeneous event class, have been shown to actually decompose into sufficiently distinct aspectual types. Davidsonian and Kimian statives (Maienborn 2008;Rothmayr 2009), for instance, show a major contrast in presence/absence of event-related properties, including finer-grained (sub)class distinctions. Within the Davidsonian (mixed eventive-stative) type, a novel class has been identified using Spanish data as reference (Marín and McNally 2011). This class, dubbedinchoative stativeis characterized by including a left boundary (Piñón 1997) marking the temporal onset of the state. We focus on documented Old Spanish data to argue that non-eventive (Kimian-like) left-bounded states are also possible. We note that productive combinations of the locative copulaestar‘be-loc’ with past participles of specific verbs produce distinct selectional and interpretive patterns defined by (i) pure states (homogenous spatial situation); (ii) no change-of-state/location denotation; (iii) left boundary. If correct, data suggest thatinchoative stativityis not necessarily a Davidsonian type of predication; and that two distinct types of inchoative statives should be carefully differentiated under (more) specific criteria.
Cat owners’ disenfranchised guilt and its predictive value on owners’ depression and anxiety
Authors: Kogan Lori R. , Currin-McCulloch Jennifer , Bussolari Cori , Packman Wendy 
Published: December 2023

Abstract
Numerous studies have found pets to have a beneficial effect on people’s psychological well-being, yet a growing body of research suggests that the positive impact of pet ownership is more complex than once thought and does not always lead to improved owner physical and mental health. One potential drawback to pet ownership is pet-related guilt. Research pertaining to work-family conflict and parental guilt has traditionally focused on human family members, yet the majority of pet owners consider their pets to be family members. Similar to parental guilt, dog-related guilt has been found to be associated with feelings of anxiety, depression, and reduced psychological health. The current study was designed to expand on dog-related guilt research by assessing cat owners. An online, anonymous, cross-sectional survey was distributed through Prolific and resulted in 604 responses for analysis. Multiple linear regression was used to predict owner depression. Gender, age, social compensatory techniques, and two guilt factors (Attention and Veterinary-related) significantly predicted depression scores. Participants’ anxiety scores, assessed with multiple linear regression, were predicted by gender, age, social compensatory techniques, and three guilt factors (Attention, Veterinary-related, and Lifestyle). Our results suggest that cat-related guilt, analogous to parental guilt, is a significant predictor of anxiety and depression. It is imperative that society recognize cat owners’ guilt, often disenfranchised; unrecognized; and unacknowledged, and help support owners’ efforts to mitigate this guilt in healthy ways.
On the hadronic origin of the TeV radiation from GRB 190114C

Published: December 2023

Abstract
The recently discovered TeV emission from Gamma-Ray Bursts (GRBs) has renewed the long-standing discussion about the hadronic versus leptonic origin of the observed GRB radiation. In this work, we investigate the possibility that the very high energy gamma rays observed by MAGIC from GRB 190114C (with energy from ∼0.1 to ∼0.8 TeV) are originated in a hadronic model.
We developed a Monte Carlo (MC) simulation of the source internal state dynamics and of the photo-hadronic interactions at internal shock. We included in the simulation also the pair production process that the secondary gamma rays undergo in the GRB jet.
We find upper limits on the internal shock model parameters by comparing our simulations to the sub-TeV observations of GRB 190114C.
Neutrino flux predictions by the model are found to be consistent with experimental upper limits set by ANTARES and IceCube.
Probing early modification of gravity with Planck, ACT and SPT
Authors: Franco Abellán Guillermo , Braglia Matteo , Ballardini Mario , Finelli Fabio , Poulin Vivian 
Published: December 2023

AbstractWe consider a model of early modified gravity (EMG) that was recently proposed as a candidate to resolve the Hubble tension. The model consists of a scalar fieldσwith a nonminimal coupling (NMC) to the Ricci curvature of the formF(σ) = Mpl2+ξσ2and an effective mass induced by a quartic potentialV(σ) = λσ4/4. We present the first analyses of the EMG model in light of the latest ACT DR4 and SPT-3G data in combination with fullPlanckdata, and find a ≳ 2σ preference for a non-zero EMG contribution from a combination of primary CMB data alone, mostly driven by ACT-DR4 data. This is different from popular `Early Dark Energy' models, which are detected only when the high-ℓ information fromPlancktemperature is removed. We find that the NMC plays a key role in controlling the evolution of density perturbations that is favored by the data over the minimally coupled case. Including measurements of supernovae luminosity distance from Pantheon+, baryonic acoustic oscillations and growth factor from BOSS, and CMB lensing ofPlanckleaves the preference unaffected. In the EMG model, the tension with SH0ES is alleviated from ∼ 6σto ∼ 3σ. Further adding SH0ES data raises the detection of the EMG model above 5σ.
From the string vacuum to FLRW or de Sitter via α' corrections
Authors: Conzinu P. , Fanizza G. , Gasperini M. , Pavone E. , Tedesco L. , Veneziano G. 
Published: December 2023

Abstract
We first make more precise a recent “Hamiltonian” reformulation of the Hohm-Zwiebach approach to the tree-level, O(d,d)-invariant string cosmology equations at all orders in the α' expansion, and recall how it allows to give a simple characterization of a large class of cosmological scenarios connecting, through a non-singular bounce, two duality-related perturbative solutions at early and late times. We then discuss the effects of adding to the action a non-perturbative, O(d,d)-breaking, dilaton potential V(ϕ). The resulting cosmological solutions, assumed to approach at early times the perturbative string vacuum (with vanishing curvature and string coupling), can stabilize the dilaton at late times and simultaneously approach either a matter-dominated FLRW cosmology or a de-Sitter-like inflationary phase, depending on initial conditions and on the properties of V(ϕ) at moderate-coupling. We also identify a general mechanism for generating isotropic late-time attractors from a large basin of anisotropic initial conditions.
A generic formation mechanism of ultralight dark matter solar halos
Authors: Budker Dmitry , Eby Joshua , Gorghetto Marco , Jiang Minyuan , Perez Gilad 
Published: December 2023

Abstract
As-yet undiscovered light bosons may constitute all or part of the dark matter (DM) of our Universe, and are expected to have (weak) self-interactions. We show that the quartic self-interactions generically induce the capture of dark matter from the surrounding halo by external gravitational potentials such as those of stars, including the Sun. This leads to the subsequent formation of dark matter bound states supported by such external potentials, resembling gravitational atoms (e.g. a solar halo around our own Sun).
Their growth is governed by the ratio ξ
foc ≡ λdB/R
⋆ between the de Broglie wavelength of the incoming DM waves, λdB, and the radius of the ground state R
⋆.
For ξ
foc ≲ 1, the gravitational atom grows to an (underdense) steady state that balances the capture of particles and the inverse (stripping) process. For ξ
foc ≳ 1, a significant gravitational-focusing effect leads to exponential accumulation of mass from the galactic DM halo into the gravitational atom.
For instance, a dark matter axion with mass of the order of 10-14 eV and decay constant between 107 and 108 GeV would form a dense halo around the Sun on a timescale comparable to the lifetime of the Solar System, leading to a local DM density at the position of the Earth 𝒪(104) times larger than that expected in the standard halo model. For attractive self-interactions, after its formation, the gravitational atom is destabilized at a large density, which leads to its collapse; this is likely to be accompanied by emission of relativistic bosons (a `Bosenova').
A run-and-tumble particle around a spherical obstacle: the steady-state distribution far-from-equilibrium
Authors: de Pirey Thibaut Arnoulx , van Wijland Frédéric 
Published: December 2023

Abstract
We investigate the steady-state distribution function of a run-and-tumble particle (RTP) evolving around a repulsive hard spherical obstacle. We demonstrate that the well-documented activity-induced attraction translates into a delta-peak accumulation at the obstacle’s surface accompanied by an algebraic divergence of the density profile close to the obstacle. We obtain the full form of the distribution function in the regime where the typical distance run by the particle between two consecutive tumbles is much larger than the obstacle’s size. This finding provides an expression for the low-density pair distribution function of a fluid of highly persistent hard-core RTP. It also advances an expression for the steady-state probability distribution of highly ballistic active Brownian particles and active Ornstein–Uhlenbeck particles around hard spherical obstacles.
Uniquely regular dessins with nilpotent automorphism groups of odd prime power order
Authors: Sun Lianghong , Wang Jin 
Published: December 2023

Abstract
If a graph is cut along each edge and can be divided into many faces, the graph has been defined to be a map when each face is homomorphic to an open disk and a bipartite map called dessin. A dessin D is regular Aut (D) if action transfer on the edge set. In particular, given a finite group G, a regular dessin is uniquely regular dessin if there is only one isomorphism class of Aut (D) are isomorphic to G. In this paper, for a nilpotent automorphism group of odd prime power order and nilpotency class four, we employ group-theoretical methods to classify these uniquely regular dessins.
Effects of microalgae and stocking density on growth and survival rate of giant clam (Tridacna squamosa Lamarck, 1819) larvae

Published: December 2023

Abstract
The present study aimed to evaluate the impact of microalgae mixture and stocking density on growth and survival rate of giant clam (Tridacna squamosa) at the veliger stage. In the first experiment, giant clam larvae of the D-stage were reared in the conical fiberglass tanks and fed with combinations of microalgae, including Chaetoceros muelleri and Isochrysis galbana (1:1), and C. muelleri, I. galbana and Nannochloropsis oculata, (1:1:1). One group of giant clam larvae without feeding was used as a control. The experiment was lasted for 7 days, until the Pediveliger stage with six replicate tanks. In the second experiment, the larvae (1 day post hatched, DPH) were reared at densities of 3, 5, 7 and 9 larvae mL-1 (so-called D3, D5, D7 and D9, respectively) for a period of 7 days. Each density was randomly assigned to 6 replicate tanks. The larvae were fed once a day with a mixture of C. muelleri, I. galbana and N. oculata, (5,000 cells/ml each type of algae). At 4DPH, extracted zooxanthelle (Symbiodinium microadriaticum) was seeded into the giant clam larvae at the concentration of 5,000cells/ml once a day.
The results showed that larvae fed with C. muelleri, I. galbana and N. oculata (1:1:1) obtained the largest shell length (217.5 ± 3.1 µm), specific growth rate (SGR) 7.18 ± 0.34 (mean±SD) and the survival rate (31.5% ± 1.6%) (P<0,05). In addition, rearing densities significantly affected growth in shell length, SGR and survival rate in giant clam larvae. Of which, the larvae at D3 gained the highest shell length, SGR and survival rate. Meanwhile, the larvae at D9 had the lowest shell length, SGR and survival rate. There was no significant difference in larval survival rate between D3 and D5. Therefore, it is suggested that in the hatchery giant clam larvae reared at 5 larvae mL-1 in order to improve productivity.
Examining morphological measurement relationships to differentiate between sexes in slender mudskipper Periophthalmus gracilis (Eggert, 1935)
Authors: Van Hua U , Dinh Quang Minh , Duc Nguyen Ton Huu 
Published: December 2023

Abstract
This study developed a new method for determining the sex of Periophthalmus gracilis (Eggert, 1935) fish using morphological measurements. This alternative method could potentially overcome the limitations of traditional methods, such as dissection, which is time-consuming, invasive, and can only be performed on dead or mature fish. The researchers collected 1,288 fish samples over 12 months from different coastal regions in the Vietnamese Mekong Delta. The fish were sexed based on their gonads and measured for various morphological aspects, including total length, standard length, body height, eyeglass distance, eye diameter, mouth width, and head length. The researchers found that the relationship between total length and eye distance was the most effective in distinguishing between male and female fish. Males significantly increased eye distance than females, making it a vital measurement for sex determination. The combination of eye distance, body height, and mouth width could also be used to determine the sample collection time, whether during the wet or dry season. The study highlights the importance of using non-invasive and suitable ways to determine fish sex. The alternative method can potentially help reduce the number of fish used in traditional ways, ultimately aiding in conserving fish populations. Additionally, this study provides essential information for fishery management, as it can help estimate population sizes and sex ratios, leading to more effective and sustainable management strategies.

Authors: Tran Quyen T. H. , Nguyen Tang V. , Nguyen Hoa V. , Dang Thanh T. , Phan Thinh V. , Nguyen Cuc T. K. 
Published: December 2023

Abstract
Type I collagen is a fibrillar structure collagen, which plays an important role as the essential structural composition and mechanical scaffold of several tissues. The aim of the study was to determine the properties of type I collagen extracted from Basa fish skin using acetic acid as the extraction solvent with the assistance of pepsin. The collagen extraction yield was 520.5 mg/g of fresh fish skin on the basis of lyophilized dry weight. The denaturation temperature (Td) of collagen was 34.8 °C by measuring its viscosity. The identity and purity of collagen protein were examined by ultraviolet-visible spectroscopy (UV-Vis) at 230 nm. Based on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), the molecular weight (Mw) of collagen α1, α2, and β subunits were approximately 130, 118, and above 200 kDa, respectively. By high performance liquid chromatography (HPLC), 17 proteinogenic amino acids were found in the collagen sample, in which the hydroxyproline content was 68.3 mg/g. The scanning electron microscope (SEM) images confirmed the fibril structure of collagen. Fourier transform infrared spectroscopy (FTIR) spectrum indicated characteristic bands according to the presence of amide A, B, I, II, and III bonds in collagen chemical structure. Therefore, purified collagen obtained from this study can be further used in various fields of application.
Investigation of environmental factors on the resistance characteristic: Study case of the designed patrol boat hull

Published: December 2023

Abstract
The increase in world oil prices has led to high operational costs in the maritime sector. In this regard, it is necessary to increase efficiency in the use of fuel in the maritime transportation security sector. Resistance on the ship’s hull affects efficiency and fuel consumption. In previous studies, there have been analyses on internal factors of the ship’s hull, such as appendages, which can affect the resistance value of the ship’s hull. However, examination of the external factors, e.g., the condition of the waters during operations of patrol boats, is still scant. This study conducts a series of analyses of the influence of environmental factors on the hull resistance values, such as water density and wind speed, with five different conditions. The results of this study are expected to be a reliable reference in predicting hull performance under different environments, especially in an attempt to reduce fuel consumption due to resistance.
