Fabrication of bulk acoustic wave resonators with ultra-thin graphene electrodes for microwave applications

description: This thesis focuses on the fabrication and characterisation of a thin film bulk acoustic wave resonator (BAW) fabricated on Si/SiO2 with stacked structures of multilayer graphene (MG), ZnO thin film, and gold. The project aims to fabricate a thin film-based BAW device in which ultrathin multilayer graphene is used as the bottom electrode with ZnO thin films as the piezoelectric layer and gold thin films as the top electrode. To accomplish the aim, different protection methods are tested to protect the graphene from degradation during the high-temperature growth of ZnO in the presence of oxygen. It was found that coating graphene with a self-assembled monolayer of bis(trimethylsilyl)amine (HMDS) can effectively reduce graphene damage during the high-temperature annealing process. Furthermore, a direct deposition process of multilayer graphene on substrates using pulsed laser deposition (PLD) was adopted and optimised to reduce the fabrication process and eliminate the multiple steps associated with the CVD transfer process. It was found that by tuning laser fluence and cooling rate high conductive and continuous graphene film can be directly deposited on SiO2. The growth of graphene was further optimised on other substrates such as SrTiO3. Apart from the growth of graphene, the deposition process for the growth of ZnO thin films is also studied and optimised. ZnO thin films with a high orientation of (002) and minimum defects using PLD on silicon substrates are realised. Finally, thin film BAW devices with MG/ZnO/Au are fabricated and characterised. The theoretical working frequency of the device is calculated with modeling simulation and is also consistent with the practical measurement value. The working frequency of this thin film BAW is around 6 GHz without the need for an air cavity or Bragg reflector.

Mathematical model of dating apps influence on sexually transmitted diseases spread

description: Sexually transmitted diseases (STDs) are a group of pathogens infecting new hosts through sexual interactions. Due to its social and economic burden, multiple models have been proposed to study the spreading of pathogens. In parallel, in the ever-evolving landscape of digital social interactions, the pervasive utilization of dating apps has become a prominent facet of modern society. Despite the surge in popularity and the profound impact on relationship formation, a crucial gap in the literature persists regarding the potential ramifications of dating apps usage on the dynamics of STDs. In this paper, we address this gap by presenting a novel mathematical framework - an extended Susceptible-Infected-Susceptible (SIS) epidemiological model to elucidate the intricate interplay between dating apps engagement and the propagation of STDs. Namely, as dating apps are designed to make users revisit them and have mainly casual sexual interactions with other users, they increase the number of causal partners, which increases the overall spread of STDS. Using extensive simulation, based on real-world data, explore the effect of dating apps adoption and control on the STD spread. We show that an increased adoption of dating apps can result in an STD outbreak if not handled appropriately.
Exact Ground States and Phase Diagram of the Quantum Compass Model under an in-plane Field

description: We consider the square lattice $S$=1/2 quantum compass model (QCM) parameterized by $J_x, J_z$, under a field, $\mathbf{h}$, in the $x$-$z$ plane. At the special field value, $(h_x^\star,h_z^\star)$=$2S(J_x,J_z)$, we show that the QCM Hamiltonian may be written in a form such that two simple product states can be identified as exact ground-states, below a gap. Exact excited states can also be found. The exact product states are characterized by a staggered vector chirality, attaining a non-zero value in the surrounding phase. The resulting gapped phase, which we denote by $SVC$ occupies most of the in-plane field phase diagram. For some values of $h_x>h_z$ and $h_z>h_x$ at the edges of the phase diagram, we have found transitions between the $SVC$ phase and phases of weakly-coupled Ising-chain states, $Z$ and $X$. In zero field, the QCM is known to have an emergent sub-extensive ground-state degeneracy. As the field is increased from zero, we find that this degeneracy is partially lifted, resulting in bond-oriented spin-stripe states, $L$ and $R$, which are each separated from one another and the $SVC$ phase by first-order transitions. Our findings are important for understanding the field dependent phase diagram of materials with predominantly directionally-dependent Ising interactions.

description: Transformer-based language models (LMs) are inefficient in long contexts. We propose Dodo, a solution for context compression. Instead of one vector per token in a standard transformer model, Dodo represents text with a dynamic number of hidden states at each layer, reducing the cost of self-attention to a fraction of typical time and space. Moreover, off-the-shelf models such as LLaMA can be adapted to Dodo by efficient parameter tuning methods such as LoRA. In use, Dodo can act as either an autoregressive LM or a context compressor for downstream tasks. We demonstrate through experiments in language modeling, question answering, and summarization that Dodo retains capabilities in these tasks, while drastically reducing the overhead during decoding. For example, in the autoencoding task, Dodo shrinks context at a 20x compression ratio with a BLEU score of 98% for reconstruction, achieving nearly lossless encoding.

description: A composite likelihood is an inference function derived by multiplying a set of likelihood components. This approach provides a flexible framework for drawing inference when the likelihood function of a statistical model is computationally intractable. While composite likelihood has computational advantages, it can still be demanding when dealing with numerous likelihood components and a large sample size. This paper tackles this challenge by employing an approximation of the conventional composite likelihood estimator, which is derived from an optimization procedure relying on stochastic gradients. This novel estimator is shown to be asymptotically normally distributed around the true parameter. In particular, based on the relative divergent rate of the sample size and the number of iterations of the optimization, the variance of the limiting distribution is shown to compound for two sources of uncertainty: the sampling variability of the data and the optimization noise, with the latter depending on the sampling distribution used to construct the stochastic gradients. The advantages of the proposed framework are illustrated through simulation studies on two working examples: an Ising model for binary data and a gamma frailty model for count data. Finally, a real-data application is presented, showing its effectiveness in a large-scale mental health survey.

Remarks
The two specimens examined from Telengana show a unique violet colour that is not present in Central Asian specimens. Besides this striking colour pattern, they morphologically match Chrysis musa Semenov-Tian-Shanskij, described from Iran, whose types were illustrated by Rosa et al. (2017a, 2021a). Examination of additional material from both localities is needed to evaluate whether the Indian specimens represent a distinct species or a colour variation.

description: [[Genus Acanthopagrus Peters]]
Acanthopagrus, now widely recognized as a valid Indo-West Pacific genus (Weber & de Beaufort, 1936; Akazaki, 1962; Smith & Smith, 1986; Carpenter, 2001), was first proposed as a subgenus of Chrysophrys by Peters (1855). The type-species of the genus is Chrysophrys vagus Peters (1852) which was later synonymized with A. berda by Smith & Smith (1986). There are eight currently recognized species of Acanthopagrus (Eschmeyer, 1998, 2005), of which A. berda is the most widespread (Fowler, 1933; Akazaki, 1962; Carpenter, 2001). Acanthopagrus berda (Forsskål, 1775), known as the “Picnic Seabream ”, is characterized by a generally silvery gray color on head, body and fins, 3 ½ scale rows between middle of spinous dorsal fin and lateral line, a fairly deep body, soft-rayed part of anal fin rounded posteriorly, and absence of single enlarged molar posteriorly in jaws as observed in the genus Rhabdosargus (Smith & Smith, 1986, see fig. 183.37 of p. 593; see fig. 8 of Carpenter, 2001). The holotype (ZMUC-P 50555, left dried skin, ca. 213 mm SL, type locality Red Sea) of Acanthopagrus berda has a strong concavity on the ventral edge of the first two infraorbitals above the posterior part of upper jaw (Fig. 1B, Fig. 2A and 2D). This character is a unique feature of this species of Acanthopagrus. After examination of numerous specimens of A. berda from many localities throughout the Indo-Pacific, we discovered three specimens labeled as A. berda from Taiwan that differed from this species by a number of characters. These specimens did not have a strong concavity on the ventral edge of the first two infraorbitals above the posterior part of upper jaw, even in the largest individual. In addition, they differed from A. berda in the following characters: cheek scale rows 3 or 4, thin upper and lower lips, prominent ridge on dorsal profile in front of eye in older individuals, head and body black with a strongly contrasting whitish belly and chin in older individuals, a dark spot at upper base of pectoral fins, and molar teeth more flattened.
The authors rechecked all known nominal species in the genus Acanthopagrus and determined that the six specimens from Taiwan represent an undescribed species. The authors herein describe A. taiwanensis n. sp. on the basis of these specimens. Nominal species synonymized with A. berda are discussed and observations are provided for other congeners.

Distribution
India (Himachal Pradesh (!), Maharashtra).
Remarks
The specimen from Simla [= Shimla] has a sparser punctation of the body, which produces a shining reflection. The same punctation was observed in a specimen from Pakistan (Rosa et al. 2021b). Du Buysson identified the Indian specimen from Simla to be a distinct variation of Chrysis speculata, and this case deserves future analyses based on more specimens and both sexes. In Europe a similar case was documented between the common Chrysis germari Wesmael, 1839 and the Alpine endemic species Chrysis lucida Linsenmaier, 1951, in the succincta group. The latter is found only at high altitudes and shows a shallower and sparser punctation, generating a shiny metallic reflection on the body, hence the species name.

Remarks. Some authors only recognize a few genera such as Venericardia Lamarck, 1801, and Cardita Bruguière, 1792, and a large number of subgenera (e.g. Claibornicardia Stenzel & Krause, 1957, Venericor Stewart, 1930, Megacardita Sacco, 1899); however, some of those taxa are ranked as genera by other authors (for comparisons of different approaches see Sacco 1899; Dall 1903; Chavan 1969; Moore 1992, McClure & Lockwood 2015). As the use of subgenera implies closer phylogenetic relationship within each group than between these groups (Dubois 1982), we will regard all supraspecific groups as genera, discarding a priori any phylogenetic inferences until a thorough phylogenetic study of the family is carried out.
Chavan (1969) outlined a classification with seven subfamilies mainly based on shell outline and hinge morphology. As a result, members of the venericardids of Harris (1919), Gardner & Bowles (1939) and Heaslip (1968) were indistinctly included in the subfamilies Carditamerinae, Venericardiinae or Carditesinae. In this paper, we reject Chavan’s (1969) approach because it ignores the phylogenetic proposals by Harris (1919) and Heaslip (1968). A comparison among genera discussed in the text is presented in Table 2.

description: We address the problem of coding for classical broadcast channels, which entails maximizing the success probability that can be achieved by sending a fixed number of messages over a broadcast channel. For point-to-point channels, Barman and Fawzi found in~\cite{BF18} a $(1-e^{-1})$-approximation algorithm running in polynomial time, and showed that it is \textrm{NP}-hard to achieve a strictly better approximation ratio. Furthermore, these algorithmic results were at the core of the limitations they established on the power of non-signaling assistance for point-to-point channels. It is natural to ask if similar results hold for broadcast channels, exploiting links between approximation algorithms of the channel coding problem and the non-signaling assisted capacity region.
 In this work, we make several contributions on algorithmic aspects and non-signaling assisted capacity regions of broadcast channels. For the class of deterministic broadcast channels, we describe a $(1-e^{-1})^2$-approximation algorithm running in polynomial time, and we show that the capacity region for that class is the same with or without non-signaling assistance. Finally, we show that in the value query model, we cannot achieve a better approximation ratio than $Ω\left(\frac{1}{\sqrt{m}}\right)$ in polynomial time for the general broadcast channel coding problem, with $m$ the size of one of the outputs of the channel.

description: Genus Cyclocardia Conrad, 1867
Type species. Cardita borealis Conrad, 1831 (pl. 8, fig. 1) (subsequent designation by Stolickza, 1871). Pleistocene–Recent, Northwest Atlantic Ocean.
Diagnosis. Carditid with thick shell, subcircular outline and convex dorsal margin. Umbo rounded. Right anterior tooth small, middle tooth very curved, broad and thick. Left anterior tooth large and posterior tooth strong and very curved. External sculpture of 15 to 27 entire and smooth radial ribs, that are low and covered by small subcircular or subrectangular nodes. Periostracum coarse and hirsute in living species.
Included species. Cyclocardia is an Eocene to Recent cosmopolitan genus that includes more than a hundred species (Maxwell 1969; Coan 1977; Stilwell & Zinsmeister 1992; Kafanov et al. 2001; Huber 2010; Güller & Zelaya 2013).
Remarks. Conrad (1867) highlighted that this genus was characterized by a thick shell with a coarse periostracum, generally smooth radial ribs and strongly inclined posteriorly hinge teeth. Subsequently, Stewart (1930) indicated that Cyclocardia has grooved hinge teeth, but that character is not found in all species.
According to Heaslip (1968), Cyclocardia has some convergent characters with planicostate carditids, such as the development of a thick shell with low and smooth radial ribs, and pointed out that the sculpture of juvenile specimens is similar to alticostate carditids, inferring that Cyclocardia could have originated within this group.
The most ancient records of Cyclocardia are represented by the Eocene C. mesembria Stilwell & Zinsmeister, 1992 (Marambio Island, La Meseta Formation, Antarctica), C. steinekei Clark & Dunham, 1946 (El Carmen District, unnamed formation, Colombia), C. otatsumei Uozomi, 1955 (Hokkaido, Wakkanabe Formation, Japan), C. ezoensis (Takeda, 1953) and C. hamiltonensis (Clark, 1932) (Kamchatka, Aluginskaya Formation, Russia) and by C. caumontiensis (Cossmann & Pisarro, 1904) (Paris Basin, France).
Cyclocardia is represented by four Patagonian species (C. cannada, C. dalek n. sp., C. nortensis and C. compressa) and is the most diverse carditid genus in the region. According to the large amount of intraspecific variability on this genus, Huber (2010) proposed the existence of at least three subgenera within Cyclocardia. As already discussed by Maxwell (1969), New Zealand representatives may belong to a different lineage or genus (see ‘ C. ’ nortensis below).
