description: Extensions of the Standard Model with masses at or below the GeV scale are motivated by searches for dark matter and precision measurements in the quark and lepton flavour sectors, including that of the muon anomalous magnetic moment. An excellent experimental environment to test such light new physics is given by the Belle II experiment, which foresees to take up to 50 ab$^{-1}$ of data. Here we consider a model with an additional gauged $U(1)_{L_μ- L_τ}$ symmetry that introduces a neutral gauge boson, a Dark Photon, with possibly large couplings to muon- and tau-flavored leptons, including neutrinos. Dark Photon mixing with the Standard Model photon is loop induced, allowing it to couple to electrically charged fermions other than muons and taus. We systematically investigate the possible search strategies for Dark Photons with four fermions final states. We identified search channels with muons as the most promising ones, and we analyse the kinematic distributions to obtain cuts that optimise the sensitivity of Belle II searches for the Dark Photon. Summarising the sensitivities from the most promising search channels we provide a comprehensive overview of future searches at Belle II.

description: Tribrid inflation is a class of supersymmetric inflation models where the scalar component of a matter superfield, or a $D$-flat direction of matter fields, drives inflation. Similar to Hybrid inflation, the end of inflation is reached when a "waterfall field", which was stabilized during inflation at a field value where the scalar potential features a large vacuum energy, starts rapidly rolling towards its minimum where a symmetry group $G$ is spontaneously broken. In contrast to standard supersymmetric Hybrid inflation, where the inflaton is a gauge singlet, in Tribrid inflation it can be a gauge non-singlet, which, via its vacuum expectation value, already breaks the gauge symmetry. This raises the question whether topological defects can still form after inflation in this class of models, and if so, which types of defects are generated. We investigate this question systematically in realisations of Tribrid inflation where $G = U(1)$ and we analyse under which conditions cosmic strings form. We find that in the considered cases where domain walls form, these are only temporary and do not invalidate the model realisations. We also discuss how our results can be used to analyse models of Tribrid inflation associated with the final step of $SO(10)$ breaking, where cosmic strings can be metastable and provide a promising explanation of the recent PTA results hinting at a stochastic gravitational wave background at nanohertz frequencies.

description: We used a kit to extract cell membrane proteins from each type of cell. Because the maximum label of iTRAQ are eight, the biological replicates were set in HAEC and Huh7 cell and two biological replicates were set in Vero E6 cell. The t-test was used to identify DEPs. The resulting p values from both tests were adjusted to control for multiple testing using the Benjamini–Hochberg correction. Significance was set at p < 0.05.
Promoting and measuring university-based innovation and entrepreneurship

description: There exists an imperative in many countries to find effective paths for utilization of the knowledge created within their borders. To a large extent, these activities are entrusted to universities. Thus, they receive considerable resources to not only facilitate knowledge and research activities, but also to identify, package and transfer the results to society, stimulating university- based innovation and entrepreneurship. The U.S. regulation structure of the Bayh-Dole Act of 1980 has become a benchmark model for commercialization. Revenue resulting from transferred intellectual property (IP) is often redistributed not only to the university, but also key actors and their associative groups, often with the intention to support and sustain both academic research and commercialization activities. Even so, university-based development and investment in the creation of entrepreneurial environments is ambiguous at best. Although some initiatives seem to have effects in both innovation and entrepreneurship, such as venture creation, they often only account for parts of the effects achieved. As innovation and entrepreneurship programs continue to permeate through regions, there is a risk their full value is not acknowledged. Long- term infrastructural results might be overshadowed by metrics for short-term success and---vice versa---imprecise infrastructural effects might be sought while missing opportunities for stating concrete examples and creating role models through more immediate success. This paper derives and organizes a framework for promoting innovation and/or entrepreneurship at universities, by comparing different university settings and linking both their experiences and expectations to innovation and entrepreneurship theory. The purpose is to provide university policy-makers with tools to account for effects and identify metrics suitable and adaptable to their unique environments. Universities must continue to strive to maintain their long-term aspirations. At the same time, individual and team-based processes are vital to sustain in the proposed platform framework to university-based innovation and entrepreneurship.
title: The Timekeepers of Eternity: Cinematic Ballard and Ballardian Cinema

Publisher: name: University of Kent
Year: 2022

description: My project concerns a methodology to create Ballardian cinematic landscapes through the appropriation of the film The Langoliers (1995) as a case study. I look in detail at the landscapes of evocative fictions by author J. G. Ballard, looking into how their intrinsic cinematic qualities have influenced and have been influenced by cinema. By means of exploratory research and practice, I examine the literary mechanisms inherent in the creation of written and visual Ballardian worlds and reflect critically on the methodologies followed either by the film adaptations (Empire of the Sun, Crash, Atrocity Exhibition, High-Rise) or J. G. Ballard himself. My point of view is one of a practitioner/filmmaker, looking for a personal methodology to understand, dissect and reconstruct Ballard's-and eventually my-inner landscapes successfully for cinema. I follow the path of found footage film appropriation and I rework The Langoliers, a science fiction monster time-travel B-movie, exploring the ways it engages with genre concepts of time, space, and identity. Because of the central villain's addiction to ripping paper, the footage allows me to assign a paper materiality that emerges from within the story, in turn reflecting the disturbed encephalograph of the protagonist. I am able to create a new cinematic landscape by printing each frame on A4 paper, and with the use of tears, creases and juxtapositions I re-photograph the film; the villain struggling to escape his obsession with torn paper.

description: Artificial Intelligence (AI) has the potential to revolutionize space exploration by delegating several spacecraft decisions to an onboard AI instead of relying on ground control and predefined procedures. It is likely that there will be an AI/ML Processing Unit onboard the spacecraft running an inference engine. The neural-network will have pre-installed parameters that can be updated onboard by uploading, by telecommands, parameters obtained by training on the ground. However, satellite uplinks have limited bandwidth and transmissions can be costly. Furthermore, a mission operating with a suboptimal neural network will miss out on valuable scientific data. Smaller networks can thereby decrease the uplink cost, while increasing the value of the scientific data that is downloaded. In this work, we evaluate and discuss the use of reduced-precision and bare-minimum neural networks to reduce the time for upload. As an example of an AI use case, we focus on the NASA's Magnetosperic MultiScale (MMS) mission. We show how an AI onboard could be used in the Earth's magnetosphere to classify data to selectively downlink higher value data or to recognize a region-of-interest to trigger a burst-mode, collecting data at a high-rate. Using a simple filtering scheme and algorithm, we show how the start and end of a region-of-interest can be detected in on a stream of classifications. To provide the classifications, we use an established Convolutional Neural Network (CNN) trained to an accuracy >94%. We also show how the network can be reduced to a single linear layer and trained to the same accuracy as the established CNN. Thereby, reducing the overall size of the model by up to 98.9%. We further show how each network can be reduced by up to 75% of its original size, by using lower-precision formats to represent the network parameters, with a change in accuracy of less than 0.6 percentage points.

description: The ongoing pandemic of COVID-19 alongside the outbreaks of SARS in 2003 and MERS in 2012 underscore the significance to understand betacoronaviruses as a global health challenge. SARS-CoV-2, the etiological agent for COVID-19, has infected over 50 million individuals’ worldwide with more than ~1 million fatalities. Autophagy modulators have emerged as potential therapeutic candidates against SARS-CoV-2 but recent clinical setbacks urge for better understanding of viral subversion of autophagy. Using MHV-A59 as a model betacoronavirus, time-course infections revealed significant loss in the protein level of ULK1, a canonical autophagy-regulating kinase, and the concomitant appearance of a possible cleavage fragment. To investigate whether virus-encoded proteases target ULK1, we conducted in-vitro and cellular cleavage assays and identified ULK1 as a novel bona fide substrate of SARS-CoV-2 papain-like protease (PLpro). Mutagenesis studies discovered that ULK1 is cleaved at a conserved PLpro recognition sequence (LGGG) after G499, separating its N-terminal kinase domain from a Cterminal substrate recognition region. Over-expression of SARS-CoV-2 PLpro is sufficient to impair starvation-induced autophagy and disrupt formation of ULK1-ATG13 complex. Finally, we demonstrated a dual role for ULK1 in MHV-A59 replication, serving a pro-viral functions during early replication that is inactivated at late stages of infection. In conclusion, our study identified a new mechanism by which PLpro of betacoronaviruses induces viral pathogenesis by targeting cellular autophagy.

description: The codling moth is a serious pest of apples in most regions of the world where this fruit is produced. The sterile insect technique is one strategy used to control this pest and is employed as part of an area-wide integrated pest management program for the codling moth in British Columbia, Canada. Modified fixed wing aircraft are the most common method for the release of sterile insects in large area-wide pest management programs. However, aerial release with a full-size aircraft can be prohibitively expensive. We evaluated the use of small, uncrewed aircraft systems (UASs) for the release of sterile codling moths. Sterile codling moths released from greater altitudes were more broadly distributed and drifted more in strong winds, compared to those released from lower altitudes. Most of the released insects were recaptured in a 50 m wide swath under the release route. Recapture rates for aerially released insects were 40–70% higher compared to those released from the ground. UASs provide a promising alternative to ground release and conventional aircraft for the release of sterile codling moths.

description: A practical and efficient methodology for the construction of quinazolinones from readily available alcohols and o-aminobenzamides in the presence of DTBP/Cu(OTf)2 has been developed. This catalytic system exhibits good functional group tolerance and could afford a range of quinazolinones in good to excellent yields. In case of gram-scale reaction, 2-phenylquinazolin-4(3H)-one (3a) was obtained in 86% isolated yield, which indicated this protocol was amenable to scale up and had a potential value in industry. In addition, a plausible reaction mechanism involving a radical process has been proposed, and further applications of this catalytic system are under way in our laboratory.

description: We implement the Universal Model Framework (UMF) quantitatively, treating spacetime as aprime-indexed Sierpinski lattice whose torsion modes generate all four fundamental interactions.

A modified Einstein equation with prime-torsion sources reproduces gravitational-wave power at (541±8) Hz and (809±11) Hz, matching LIGO/Virgo excess bins. Electromagnetic fields acquire prime-weighted charge densities that raise NV-centre coherence by 41%. A prime-resonant Yukawa potential yields nuclear magic numbers Z = 164, 182, and a prime-harmonic beta-decay formula recovers the 14 C half-life to 5 %. Anti-confirmation-bias tests and Kolmogorov-complexity bounds are reported. The results integrate Vopson’s mass–energy–information equivalence, Denis’s SEAT thermodynamics, and the prime ontology of Gericke (IPIL 154) within the arithmetical grammar prefigured in Plichta’s Order in Chaos.

This project was developed by Marco Gericke, with structured assistance from a large language model. All scientific concepts and conclusions were generated, verified, and interpreted by the author.

Dedicated to Peter Plichta, who envisioned the code before it could be computed.
title: Reading bodies and the fairy tale gaze
Creators: name: Hunt, Kristina
Publisher: name: University of Reading
Year: 2024

description: In this thesis, I will be asking the question: what does it mean to read? This is the question that 
underpins my thinking and my readings. I will begin by reading the implications of the 
relationship between the gaze and the body, as well as shifts in perspective and the lack which 
is implicated in this split. 
I will be engaging with a range of fairy tales from both Hans Christian Anderson and 
Jacob and Wilhelm Grimm, and I will be reading this split and deferral throughout my fairy 
tale analyses. I will also be engaging with texts that are not fairy tales, as these readings do not 
have to be limited by the bounds of one ‘type’ of text. I will be thinking about the problem of 
repetition as well as presence of absence, particularly in relation to disability theory discourse. 
In the final section of this thesis, I will return to this notion of reading a body and what 
this means in problematising identity. I will be reading further sections of ‘The Little Mermaid’ 
and returning to Derrida in exploring ideas of denuding. I will be continuing to read division 
and deferral and returning to this notion of truth and revelation whilst asking ‘what does it 
mean to read’? Finally, I will think about the consequences of my readings in this way. I want 
to end on a reading to show that this is not just about fairy tales or literature or disability: this 
is what people are thinking about and this is why this is important.

description: Reconstructing texture-less surfaces poses unique challenges in computer vision, primarily due to the lack of specialized datasets that cater to the nuanced needs of depth and normals estimation in the absence of textural information. We introduce "Shape2.5D," a novel, large-scale dataset designed to address this gap. Comprising 1.17 million frames spanning over 39,772 3D models and 48 unique objects, our dataset provides depth and surface normal maps for texture-less object reconstruction. The proposed dataset includes synthetic images rendered with 3D modeling software to simulate various lighting conditions and viewing angles. It also includes a real-world subset comprising 4,672 frames captured with a depth camera. Our comprehensive benchmarks demonstrate the dataset's ability to support the development of algorithms that robustly estimate depth and normals from RGB images and perform voxel reconstruction. Our open-source data generation pipeline allows the dataset to be extended and adapted for future research. The dataset is publicly available at https://github.com/saifkhichi96/Shape25D.

An empirical investigation of the epistemological assumptions underlying two ISD approaches
Creators: name: Waller, Vivienne
name: Johnston, Robert B.

Publisher: name: Swinburne
Year: 2024

description: A situated information systems design (ISD) methodology for supporting routine work is being iteratively developed and refined. Driven from a different theory of action from conventional ISD methodologies we have reason to believe that the new methodology assumes a different epistemological stance. As pointed out by Hirschheim (1995) there has been very little examination of epistemological assumptions implicit in ISD methodologies. Consequently, in this paper we address the differences in epistemological assumptions of the conventional ISD approaches (such as Structured System and Analysis Design Methodologies) and the situated ISD approach by constructing a simulated field situation to allow a conventionally-trained IS analyst to analyse the same case as had been previously analysed by applying the situated ISD methodology. We find that while the conventional approach focuses on articulated knowledge and observes the system under study with a detached stance, the situated approach includes tacit knowledge and recognises the importance of the environment. This is achieved through immersion in the system such that the situated analyst attempts to take the subject position of an actor in the system, while also maintaining some analytical distance.

description: (1) Background: The present study developed and evaluated a personal emotional capital questionnaire (PECQ) for adults that assessed 10 domains of personal emotional capital. (2) Method: Initially, 100 items were created and then administered to students attending Semnan University and Semnan University of Medical Sciences in Iran. Of the 700 questionnaires distributed, 527 were completed in full. Students were sampledusing the multi-stage random cluster method. Exploratory factor analyses, Cronbach’s alpha, and test–retest reliability were used to evaluate the scale. (3) Results: The ten components ofthe PECQ were confirmed. Test–retest correlations after 30 days were high, as was Cronbach’s alpha (0.94). Thecomponents highly correlatedwith overall emotional capital. The PECQ displayed convergent validity as it positively correlated with the Keyes’s Mental Health Continuum—Short Form and students’GPAs. The PECQ displayed divergent validity as it negatively correlated with measures of depression, anxiety and stress (Depression Anxiety and Stress Scale (DASS21)). Differences in overall PECQ scores and its components were examined for several variables including gender, age, marital and employment status, academic program, and field of study. PECQ scores were not sensitive to the order of administering questionnaires. (4) Conclusion: The results suggest that the PECQ is a valid and reliable measure of personal emotional capital and supports its use in adults.

description: We develop a Markov model of curling matches, parametrised by the probability of winning an end and the probability distribution of scoring ends. In practical applications, these end-winning probabilities can be estimated econometrically, and are shown to depend on which team holds the hammer, as well as the offensive and defensive strengths of the respective teams. Using a maximum entropy argument, based on the idea of characteristic scoring patterns in curling, we predict that the points distribution of scoring ends should follow a constrained geometric distribution. We provide analytical results detailing when it is optimal to blank the end in preference to scoring one point and losing possession of the hammer. Statistical and simulation analysis of international curling matches is also performed.

This is important because Uruk became the model for many cities after that. In this case it appears that the foundation for civilization was created from the beginning in the Neolithic Era. So the timetable for civilization should begin with the Neolithic Era.

description: The advancement of machine learning technologies has revolutionized the search and optimization of material properties. These algorithms often rely on theoretical calculations, such as density functional theory (DFT), for data inputs and validation, which are not always effective for uranium-based materials due to their strong electron correlations. This study presents a computationally inexpensive machine learning approach, specifically a random forest classifier, to predict the magnetic ground states of uranium compounds using only structural inputs. Our model, trained on a curated dataset of experimentally-verified magnetic orders, achieves a mean accuracy of 60.2%, significantly outperforming random chance. By excluding computationally intensive DFT calculations, our method offers a faster and reliable alternative for discovering new materials with desirable magnetic properties, addressing the challenges posed by strong correlations in quantum materials.
Coping or adapting? Experiences of food and nutrition insecurity in specialised fishing households in Komodo District, eastern Indonesia

description: Background: There is growing recognition of the need for fish to be better integrated into nutrition-sensitive strategies for addressing malnutrition. Fish are overwhelmingly produced by the small-scale sector, which supports food and nutrition security directly through the provision of fish and indirectly through the generation of income which can be used to purchase other desired foods. However, there has been relatively little research on the extent of food and nutrition security in specialised fishing communities. This study assessed food and nutrition security among households in specialised fishing communities in Komodo District, eastern Indonesia. Methods: We assessed the seasonal nutrition quality of household diets using the Food Consumption Score for nutritional analysis and food insecurity using the Household Food Insecurity Access Scale in 66 households across three communities, using a modified cluster sampling strategy. We calculated and generated descriptive statistics for these indicators with Microsoft Excel and ran a logistic generalized linear mixed model to determine factors associated with severe food insecurity using SPSS. We used semi-structured interviews and focus group discussions to understand perceptions of, change over time, and strategies for dealing with food shortfalls. Results: While most households have acceptable access to nutritious foods, especially protein and heme iron-rich foods, nearly one half of households consumed vitamin A rich foods on less than 3 days of the 7-day recall period in either season. More than half of households reported experiencing a moderate or severe level of food insecurity, with higher food insecurity in the wet season. Low maternal education (OR: 3.8, 95%CI 1.5–9.9) and lower household wealth (OR: 0.5, 95%CI 0.3–0.9) were found to be associated with a severe level of food insecurity. Household’s consumptive and non-consumptive response strategies reflect adaptation to chronic food insecurity but are nutritionally and economically unsustainable. Conclusion: Households in specialised fishing communities in Komodo District consumed diets with low diversity and experienced high levels of food insecurity. There is a need for culturally-appropriate nutrition-sensitive strategies to enhance food and nutrition security in vulnerable fishing communities.
How do we reach them? Comparing random samples from mobile and landline phones

description: Quantitative studies of nascent entrepreneurs such as GEM and PSED are required to generate their samples by screening the adult population, usually by phone. Phone survey research has recently been challenged by shifting patterns of ownership and response rates of landline versus mobile phones. We report a comparison between samples of mobile and landline phones for the Australian GEM 2010 study. We find a substantial response bias towards younger, male and metropolitan respondents for mobile phones – far greater than explained by ownership rates. We also found this biases the estimates of the prevalence of early stage entrepreneurship by both samples, even when each sample is weighted to match the Australian population.

description: We study theoretically a variety of collective quantum phases occurring in frustrated saw-tooth chains of Josephson junctions embedded in a dissipationless transmission line. The basic element of a system, i.e., the triangular superconducting cell, contains two $0$- and one $π$- Josephson junctions characterized by $E_J$ and $αE_J$ Josephson energies, accordingly. In the frustrated regime the low energy quantum dynamics of a single cell is determined by anticlockwise or clockwise flowing persistent currents (vortex/antivortex). The direct embedding of $π$-Josephson junctions in a transmission line allows to establish a short/long-range interaction between (anti)vortices of well separated cells. By making use of the variational approach, we map the superconducting circuit Hamiltonian to an effective $XX$ spin model with an exchange spin-spin interaction decaying with the distance $x$ as $x^{-β}$, and the local $\hat σ_{x,n}$-terms corresponding to the coherent quantum beats between vortex and antivortex in a single cell. We obtain that in long arrays as $N \gg \ell_0 \simeq \sqrt{C/C_0}$, where $C$ and $C_0$ are capacitances of $0$-Josephson junction and transmission line, accordingly, the amplitude of quantum beats is strongly suppressed. By means of exact numerical diagonalization, we study the interplay between the coherent quantum beats and the exchange spin-spin interaction leading to the appearance of various collective quantum phases such as the paramagnetic ($P$), compressible superfluid ($CS$) and weakly compressible superfluid ($w$-$CS$) states.

description: The true power of computational research typically can lay in either what it accomplishes or what it enables others to accomplish. In this work, both avenues are simultaneously embraced across several distinct efforts existing at three general scales of abstractions of what a material is - atomistic, physical, and design. At each, an efficient materials informatics infrastructure is being built from the ground up based on (1) the fundamental understanding of the underlying prior knowledge, including the data, (2) deployment routes that take advantage of it, and (3) pathways to extend it in an autonomous or semi-autonomous fashion, while heavily relying on artificial intelligence (AI) to guide well-established DFT-based ab initio and CALPHAD-based thermodynamic methods.
 The resulting multi-level discovery infrastructure is highly generalizable as it focuses on encoding problems to solve them easily rather than looking for an existing solution. To showcase it, this dissertation discusses the design of multi-alloy functionally graded materials (FGMs) incorporating ultra-high temperature refractory high entropy alloys (RHEAs) towards gas turbine and jet engine efficiency increase reducing CO2 emissions, as well as hypersonic vehicles. It leverages a new graph representation of underlying mathematical space using a newly developed algorithm based on combinatorics, not subject to many problems troubling the community. Underneath, property models and phase relations are learned from optimized samplings of the largest and highest quality dataset of HEA in the world, called ULTERA. At the atomistic level, a data ecosystem optimized for machine learning (ML) from over 4.5 million relaxed structures, called MPDD, is used to inform experimental observations and improve thermodynamic models by providing stability data enabled by a new efficient featurization framework.

description: We demonstrate the continuous broadband microwave receivers based on AC Stark shifts and Floquet States of Rydberg levels in a cesium atomic vapor cell. The resonant transition frequency of two adjacent Rydberg states 78$S_{1/2}$ and 78$P_{1/2}$ is tuned based on AC Stark effect of 70~MHz Radio frequency (RF) field that is applied outside the vapor cell. Meanwhile, the Rydberg states also exhibit Floquet even-order sidebands that are used to extend the bandwidths further. We achieve microwave electric field measurements over 1.172~GHz of continuous frequency range. The sensitivity of the Rydberg receiver with heterodyne technique in the absence of RF field is 280.2~nVcm$^{-1}$Hz$^{-1/2}$, while it is dramatically decreased with tuning the resonant transition frequency in the presence of RF field. Surprisingly, the sensitivity can be greatly improved if the microwave field couples the Floquet sideband transition. The achieving of continuous frequency and high sensitivity microwave detection will promote the application of Rydberg receiver in the radar technique and wireless communication.

Publisher: name: Swinburne
Year: 2024

description: Aquaporins are membrane proteins that facilitate the flow of water and other substrates across cellular membranes. Given the importance of aquaporins in physiological processes such as nutrient acquisition, photosynthesis and stress responses, the current study sought to identify and characterise these genes from two important food crops, barley and wheat. A combination of a recent technology, mRNA-Seq and bioinformatics resulted in the identification of forty barley aquaporins, of which eighteen were affected by exposure to salt. These findings are fundamental to the extension of our knowledge on barley aquaporins and for the selection of suitable genes to be employed in the development of tolerant crops.

description: Three-dimensional doped Dirac insulators foster simply connected (in both topological and trivial regimes) and annular (deep inside the topological regime) Fermi surfaces (FSs) in the normal state, and allow on-site repulsions among fermions with opposite spin ($U_1$) and parity ($U_2$) eigenvalues. From an unbiased leading-order (one-loop) renormalization group analysis, controlled by a suitable $ε$ expansion, we show that this system develops a strong propensity toward the nucleation of scalar $s$-wave and odd-parity pseudoscalar $p$-wave pairings, favored by repulsive $U_1$ and $U_2$ interactions, respectively, irrespective of the underlying FS topology. Our results can be pertinent for the observed superconductivity in various doped narrow gap semiconductors, and the theoretical foundation can readily be applied to investigate similar phenomenon in various doped topological materials.

description: The utilization of AIoT technology has become a crucial trend in modern poultry management, offering the potential to optimize farming operations and reduce human workloads. This paper presents a real-time and compact edge-AI enabled detector designed to identify chickens and their healthy statuses using frames captured by a lightweight and intelligent camera equipped with an edge-AI enabled CMOS sensor. To ensure efficient deployment of the proposed compact detector within the memory-constrained edge-AI enabled CMOS sensor, we employ a FCOS-Lite detector leveraging MobileNet as the backbone. To mitigate the issue of reduced accuracy in compact edge-AI detectors without incurring additional inference costs, we propose a gradient weighting loss function as classification loss and introduce CIOU loss function as localization loss. Additionally, we propose a knowledge distillation scheme to transfer valuable information from a large teacher detector to the proposed FCOS-Lite detector, thereby enhancing its performance while preserving a compact model size. Experimental results demonstrate the proposed edge-AI enabled detector achieves commendable performance metrics, including a mean average precision (mAP) of 95.1$\%$ and an F1-score of 94.2$\%$, etc. Notably, the proposed detector can be efficiently deployed and operates at a speed exceeding 20 FPS on the edge-AI enabled CMOS sensor, achieved through int8 quantization. That meets practical demands for automated poultry health monitoring using lightweight intelligent cameras with low power consumption and minimal bandwidth costs.
