description: Image-based dietary assessment serves as an efficient and accurate solution for recording and analyzing nutrition intake using eating occasion images as input. Deep learning-based techniques are commonly used to perform image analysis such as food classification, segmentation, and portion size estimation, which rely on large amounts of food images with annotations for training. However, such data dependency poses significant barriers to real-world applications, because acquiring a substantial, diverse, and balanced set of food images can be challenging. One potential solution is to use synthetic food images for data augmentation. Although existing work has explored the use of generative adversarial networks (GAN) based structures for generation, the quality of synthetic food images still remains subpar. In addition, while diffusion-based generative models have shown promising results for general image generation tasks, the generation of food images can be challenging due to the substantial intra-class variance. In this paper, we investigate the generation of synthetic food images based on the conditional diffusion model and propose an effective clustering-based training framework, named ClusDiff, for generating high-quality and representative food images. The proposed method is evaluated on the Food-101 dataset and shows improved performance when compared with existing image generation works. We also demonstrate that the synthetic food images generated by ClusDiff can help address the severe class imbalance issue in long-tailed food classification using the VFN-LT dataset.

description: The nucleus Ge77 was studied through the Ge76(C13,C12)Ge77 reaction at a sub-Coulomb energy. The angular distributions of γ rays depopulating excited states in Ge77 were measured in order to constrain spin and parity assignments. Some of these assignments are of use in connection with neutrinoless double beta decay, where the population of states near the Fermi surface of Ge76 was recently explored using transfer reactions.

description: Since the baryon-number susceptibilities are correlated with the cumulant of baryon-number fluctuations in experiments, we do calculations of the susceptibilities and compare them with the experimental fluctuation data under the framework of the Dyson-Schwinger equations (DSEs) approach. We compare our results with lattice QCD and experimental data at RHIC. The fitness of the results indicates that under the framework of DSEs, we can deal with the problems of heavy ion collisions properly.

description: We prove that, regardless of the choice of the angles $θ_1,θ_2,θ_3$, three fractional Fourier transforms $F_{θ_1}$, $F_{θ_2}$ and $F_{θ_3}$ do not solve the phase retrieval problem. That is, there do not exist three angles $θ_1$, $θ_2$, $θ_3$ such that any signal $ψ\in L^2(R)$ could be determined up to a constant phase by knowing only the three intensities $|F_{θ_1}ψ|^2$, $|F_{θ_2}ψ|^2$ and $|F_{θ_3}ψ|^2$. This provides a negative argument against a recent speculation by P. Jaming, who stated that three suitably chosen fractional Fourier transforms are good candidates for phase retrieval in infinite dimension. We recast the question in the language of quantum mechanics, where our result shows that any fixed triple of rotated quadrature observables $Q_{θ_1}$, $Q_{θ_2}$ and $Q_{θ_3}$ is not enough to determine all unknown pure quantum states. The sufficiency of four rotated quadrature observables, or equivalently fractional Fourier transforms, remains an open question.
title: Environmental implications from deep sea oil release

description: This thesis focuses on management issues of anthropogenic, natural disasters or accidents that lead to the occurrence and appearance of oil spills on the surface or the bottom of the sea. In particular, emphasis is placed on the factors that contribute to water or subsoil pollution in general, and how such issues are addressed with the aim of bringing together the emerging data on the management of petroleum-derived or by-derived contaminated wastewater and explaining the challenge and the best methods of their management. A main finding that emerged is that early prediction, appropriate engineering design, the availability of waste and toxic substance removal tools and technologies, and simulations contribute to the appropriate management of similar crises. However, how such accidents will be managed depends on the data of each incident such as, among others, the depth and extent of the destruction, the causes of the accident, environmental and weather conditions (wind strength, temperature, visibility, pressure) as well as the applicable legislative framework in an area. Then, using the Deepwater Horizon accident as a case study, it is found that the management of similar crises is an important project with an impact on the quality of life of citizens, the environment and international relations. This conclusion was reached because it was found that the difficulty in managing similar crises can lead to environmental disasters, energy shortages, loss of biodiversity, reduction of tourist traffic as well as human lives. So, the effects of such accidents are direct and indirect, short-term and long-term, and often costly and time-consuming. The Deepwater Horizon accident, being at a depth of 1,500 meters, was particularly difficult to deal with since water pressure, accessibility, visibility and the possibility of containing the oil in one area were limited. This accident, one hopes, will be an example to avoid for the future and a sample of the need to improve the methods of prevention, simulation and management of corresponding emergencies.

description: Open-vocabulary detection (OVD) is a new object detection paradigm, aiming to localize and recognize unseen objects defined by an unbounded vocabulary. This is challenging since traditional detectors can only learn from pre-defined categories and thus fail to detect and localize objects out of pre-defined vocabulary. To handle the challenge, OVD leverages pre-trained cross-modal VLM, such as CLIP, ALIGN, etc. Previous works mainly focus on the open vocabulary classification part, with less attention on the localization part. We argue that for a good OVD detector, both classification and localization should be parallelly studied for the novel object categories. We show in this work that improving localization as well as cross-modal classification complement each other, and compose a good OVD detector jointly. We analyze three families of OVD methods with different design emphases. We first propose a vanilla method,i.e., cropping a bounding box obtained by a localizer and resizing it into the CLIP. We next introduce another approach, which combines a standard two-stage object detector with CLIP. A two-stage object detector includes a visual backbone, a region proposal network (RPN), and a region of interest (RoI) head. We decouple RPN and ROI head (DRR) and use RoIAlign to extract meaningful features. In this case, it avoids resizing objects. To further accelerate the training time and reduce the model parameters, we couple RPN and ROI head (CRR) as the third approach. We conduct extensive experiments on these three types of approaches in different settings. On the OVD-COCO benchmark, DRR obtains the best performance and achieves 35.8 Novel AP$_{50}$, an absolute 2.8 gain over the previous state-of-the-art (SOTA). For OVD-LVIS, DRR surpasses the previous SOTA by 1.9 AP$_{50}$ in rare categories. We also provide an object detection dataset called PID and provide a baseline on PID.

description: We explicitly construct a configuration of ${\cal N}=4$ supersymmetry Yang-Mills theory with gauge group $U(N)$ on an interval on length $L$ with a D5-like boundary condition on one end and an NS5-like boundary condition on the other. For $N>1$, such a configuration violates the $s$-rule and is non-supersymmetric. We compute the energy relative to the BPS bound of these configurations and find that it is proportional to $N(N^2-1) g_{YM4}^{-2} L^{-3}$.

description: Transit observations of HD 209458b in the stellar Lyman-$α$ (Ly$α$) line revealed strong absorption in both blue and red wings of the line interpreted as hydrogen atoms escaping from the planet's exosphere at high velocities. The following sources for the absorption were suggested: acceleration by the stellar radiation pressure, natural spectral line broadening, charge exchange with stellar wind. We reproduce the observation by means of modelling that includes all aforementioned processes. Our results support a stellar wind with a velocity of $\approx400$ km$\times$s$^{-1}$ at the time of the observation and a planetary magnetic moment of $\approx 1.6 \times 10^{26}$ A$\times$m$^2$.

description: Excited states in Th219 have been observed for the first time in an experiment using the Mg26+Pt198 reaction and evaporation-residue-gated γ-ray spectroscopy. Two structures of interlinked alternating-parity levels with simplex quantum numbers s=±i are observed, reminiscent of similar sequences in heavier odd-mass isotopes, but only three mass units away from the N=126 neutron closed shell. The emergence of quadrupole-octupole collectivity in this mass region and the trend for parity-doublet bands are discussed.

description: Three optical telescopes located at the San Pedro Mártir National Observatory were used for the first time to obtain multi-filter defocused photometry of the transiting extrasolar planets WASP-39b and WASP-43b. We observed WASP-39b with the 2.12m telescope in the U filter for the first time, and additional observations were carried out in the R and I filters using the 0.84m telescope. WASP-43b was observed in VRI with the same instrument, and in the i filter with the robotic 1.50m telescope. We reduced the data using different pipelines and performed aperture photometry with the help of custom routines, in order to obtain the light curves. The fit of the light curves (1.5--2.5mmag rms), and of the period analysis, allowed a revision of the orbital and physical parameters, revealing for WASP-39b a period ($4.0552947 \pm 9.65 \times 10^{-7}$ days) which is $3.084 \pm 0.774$ seconds larger than previously reported. Moreover, we find for WASP-43b a planet/star radius ($0.1738 \pm 0.0033$) which is $0.01637 \pm 0.00371$ larger in the i filter with respect to previous works, and that should be confirmed with additional observations. Finally, we confirm no evidence of constant period variations in WASP-43b.

description: Discrete gauge groups naturally arise in F-theory compactifications on genus-one fibered Calabi-Yau manifolds. Such geometries appear in families that are parameterized by the Tate-Shafarevich group of the genus-one fibration. While the F-theory compactification on any element of this family gives rise to the same physics, the corresponding M-theory compactifications on these geometries differ and are obtained by a fluxed circle reduction of the former. In this note, we focus on an element of order three in the Tate-Shafarevich group of the general cubic. We discuss how the different M-theory vacua and the associated discrete gauge groups can be obtained by Higgsing of a pair of five-dimensional U(1) symmetries. The Higgs fields arise from vanishing cycles in $I_2$-fibers that appear at certain codimension two loci in the base. We explicitly identify all three curves that give rise to the corresponding Higgs fields. In this analysis the investigation of different resolved phases of the underlying geometry plays a crucial rôle.

description: Low-lying collectively excited states of Xe128 were investigated by γ-ray spectroscopy following the C12(Xe128,Xe128*)C12 projectile Coulomb excitation reaction. Nineteen absolute E2 transition strengths were obtained including the first measurement of the critical B(E2) decays from the second and third Jπ=0+ states. These data are compared with the theoretical predictions of the critical point symmetry E(5) and allow us to conclude that Xe128 is not an E(5) nucleus as previously suggested, leaving Xe130 as the most likely candidate among the Xe isotopes.

description: The isotope Rf257 was produced in the fusion-evaporation reaction Pb208(Ti50,n)Rf257. Reaction products were separated and identified by mass. Delayed spectroscopy of Rf257 and its decay products was performed. A partial decay scheme with configuration assignments is proposed based on α hindrance factors. The excitation energy of the 1/2+[620] configuration in No253 is proposed. The energy of this 1/2+ state in a series of N=151 isotones increases with nuclear charge, reflecting an increase in the N=152 gap. This gap is deduced to grow substantially from 850 to 1400 keV between Z=94 and 102. An isomeric state in Rf257, with a half-life of 160-31+42μs, was discovered by detecting internal conversion electrons followed by α decay. It is interpreted as a three-quasiparticle high-K isomer. A second group of internal conversion electrons, with a half-life of 4.1-1.3+2.4 s, followed by α decay, was also observed. These events might originate from the decay of excited states in Lr257, populated by electron-capture decay of Rf257. Fission of Rf257 was unambiguously detected, with a branching ratio of bRfSF=0.02±0.01.

description: Engineered domain structures play an essential role in nonlinear optics for quasi-phase-matched parametric processes. Pyroelectric field-assisted domain inversion with focused femtosecond laser pulses is a promising approach to create arbitrary two-dimensional nonlinear photonic structures in a large volume without externally applied electrical fields. We fabricate lattices of ferroelectric domains by patterning lithium niobate crystals with femtosecond laser pulses and then heating them to elevated temperatures. After cooling to room temperature, domains form below and above the laser-induced seeds. We investigate the effect of temperature and seed spacing on the number and size of inverted domains. In a temperature range of 220 °C-300 °C all domains are inverted in a two-dimensional lattice with periods of 15 µm × 6.3 µm. Smaller lattice periods result in a smaller fraction of inverted domains. Measurements with conducting, nonconducting, and short-circuited crystal surfaces reveal the influence of surface charges during the domain formation process. From the obtained domain widths and spacings, we calculate the effective nonlinear coefficient of quasi-phase-matched second-harmonic generation in two-dimensional nonlinear photonic structures.

ISSUES AND CHALLENGES OF CHILD LABOUR

Subjects: child labour, poverty, inequality, eradication, protection…

description: Abstract Many reasons contribute to child labour and exploitation, including poverty, societal norms that support it, a lack of appropriate jobs available for adolescents and adults migration, and emergencies. These elements are both the source and the result of socioeconomic inequalities exacerbated by prejudice. The perpetuation of child workers and exploitation endangers economic systems and has serious immediate and long-term effects for children, including denial of schooling and deterioration of physical and mental well-being. Kid labour must be prohibited to ensure that every child has the opportunity to attend school, play, and have the greatest future possible. These youngsters are frequently forced to labour in abhorrent and dangerous situations. Their rights are infringed on a regular basis. If children are employed, they are unable to attend school! This implies that these youngsters will grow to be adults with no education and no capability to read or write, depriving them of critical life skills. The vast majority of kids who work as children are from underprivileged origins, minority groups, or are taken from their families. They have no defense. Furthermore, their employers do everything possible to make them utterly hidden, so that no one understands or cares about them. They will have complete control over these youngsters this way. Slave labour also serves as an impediment to being a child, to playing and doing anything you want. This article discusses child labour, the causes of child labour, and the abolition of child labour.....

description: We present the results from deep Suzaku observations of the central region of the Perseus cluster. Bulbul et al. (2014) reported the detection by XMM-Newton instruments of an unidentified X-ray emission line at an energy around 3.5keV in spectra for the Perseus and other clusters. They argued for a possibility of the decay of sterile neutrino, a dark matter candidate. We examine Suzaku X-ray Imaging Spectrometer (XIS) spectra of the Perseus cluster for evidence in the 3.5keV line and other possible dark matter features in the 2-6keV energy band. In order to search for and constrain a weak line feature with the XIS, observations of the Crab nebula are used to evaluate the system's effective area. We found no line feature at the claimed position with a systematic line flux upper limit at a half (1.5eV in line equivalent width) of the claimed best-fit value by Bulbul et al. We discuss this inconsistency in terms of instrumental calibration errors and modeling of continuum emission. Future prospects for high-energy resolution spectroscopy with ASTRO-H are presented.

description: This research examines the challenges and needs that Trinidad and Tobago offenders face upon release from prison. The purpose of this research is to provide a foundation for policy recommendations to improve successful reintegration for prisoners corning home. Although there is a lack of re-entry literature based on Trinidad and Tobago offenders, the findings in this study show that Trinidad and Tobago offenders experience the same challenges and needs revealed by America research on offender re-entry. Study results show that policy intervention should be designed to ensure offenders returning home receive assistance with finding shelter, employment, educational resources, counseling and reunification with family and community members. These findings will point the way to policy innovations that are empirically grounded, pragmatic, and reflective of the realities of re-entry.

description: We present a sample of hard X-ray selected candidate black holes (BHs) in 19 dwarf galaxies. BH candidates are identified by cross-matching a parent sample of ~44,000 local dwarf galaxies (M_stellar < 3 x 10^9 Msun, z<0.055) with the Chandra Source Catalog, and subsequently analyzing the original X-ray data products for matched sources. Of the 19 dwarf galaxies in our sample, 8 have X-ray detections reported here for the first time. We find a total of 43 point-like hard X-ray sources with individual luminosities L(2-10 keV) ~ 10^37 - 10^40 erg/s. Hard X-ray luminosities in this range can be attained by stellar-mass X-ray binaries (XRBs), and by massive BHs accreting at low Eddington ratio. We place an upper limit of 53% (10/19) on the fraction of galaxies in our sample hosting a detectable hard X-ray source consistent with the optical nucleus, although the galaxy center is poorly defined in many of our objects. We also find that 42% (8/19) of the galaxies in our sample exhibit statistically significant enhanced hard X-ray emission relative to the expected galaxy-wide contribution from low-mass and high-mass XRBs, based on the L(2-10 keV)-M_stellar-SFR relation defined by more massive and luminous systems. For the majority of these X-ray enhanced dwarf galaxies, the excess emission is consistent with (but not necessarily due to) a nuclear X-ray source. Follow-up observations are necessary to distinguish between stellar-mass XRBs and active galactic nuclei powered by more massive BHs. In any case, our results support the notion that X-ray emitting BHs in low-mass dwarf galaxies may have had an appreciable impact on reionization in the early Universe.

description: The N ∼ 90 region of the nuclear chart has featured prominently as the spectroscopy of nuclei at extreme spin has progressed. This talk will present recent discoveries from investigations of high spin behavior in the N ∼ 90 Er, Tm and Yb nuclei utilizing the Gammasphere gamma-ray spectrometer. In particular it will include discussion of the beautiful shape evolution and coexistence observed in these nuclei along with the identification of a remarkable new family of band structures. The latter are very weakly populated rotational sequences with high moment of inertia that bypass the classic terminating configurations near spin 40-50h{stroke}, marking a return to collectivity that extends discrete γ-ray spectroscopy to well over 60h{stroke}. Establishing the nature of the yrast states in these nuclei beyond the oblate band-termination states has been a major goal for the past two decades. Cranking calculations suggest that these new structures most likely represent stable triaxial strongly deformed bands that lie in a valley of favored shell energy in deformation and particle-number space.
title: On positive braids and monodromy groups of plane curve singularities

Publisher: name: Universität Bern

Subjects: subject: 510 Mathematics

description: This thesis is situated at the intersection of knot theory, singularity theory and surface topology.
The first objects of consideration are secondary braid groups of positive braids, a conjectural braid-theoretic generalization of the local fundamental group of the discriminant complement of an isolated plane curve singularity. In particular, we prove that the secondary braid group is a link invariant for positive 3-braids. 
The main part of the thesis is concerned with the so-called monodromy group of a positive braid. First, we prove that such groups are a generalization of the geometric monodromy group of an isolated plane curve singularity. We then study those monodromy groups using the theory of framed mapping class groups. In particular, we prove that, for a prime positive braid whose closure is a knot of braid index at least 3, up to finitely many exceptions the monodromy group is a framed mapping class group. We then deduce that, under the same assumptions, the monodromy group is a knot invariant, determined by the genus and Arf invariant of the braid closure. Applied to singularity theory, this implies that the geometric monodromy group of an irreducible singularity not of type Aₙ is, up to finitely many exceptions, determined by the genus and Arf invariant of the associated knot.
Finally, we briefly consider the extension of such techniques to more general fibred knots, obtained by plumbing Hopf bands. We obtain analogous results concerning monodromy groups of arborescent Hopf plumbings.

description: The neutron-rich isotopes Fe65,67 and Co65 have been produced at the LISOL facility, Louvain-La-Neuve, in the proton-induced fission of U238. Beams of these isotopes have been extracted with high selectivity by means of resonant laser ionization combined with mass separation. Yrast and near-yrast levels of Co65 have also been populated in the Ni64+U238 reaction at Argonne National Laboratory. The level structure of Co65 could be investigated by combining all the information from both the Fe65 and Co65β decay and the deep-inelastic reaction. The Fe65, Co65, and Fe67 decay schemes and the Co65 yrast structure are fully established. The Co65,67 level structures can be interpreted as resulting from the coexistence of core-coupled states with levels based on a low-energy proton-intruder configuration.

description: Precise radial velocities from the Anglo-Australian Telescope confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AAT data shows that the inner planet has P=89.1+/-0.1 days, and m sin i=1.35+/-0.17 Mjup. These data also confirm the planetary nature of the outer companion, with m sin i=3.9+/-0.6 Mjup and a=2.96+/-0.16 AU. HD 121056 is the most-evolved star to host a confirmed multiple-planet system, and is a valuable example of a giant star hosting both a short-period and a long-period planet.

description: The expanded level structure of Pu240 available from the present study highlights the role of strong octupole correlations in this nucleus. In addition to a delayed alignment in the yrast band, the observations include the presence of both I+→(I-1)- and I-→(I-1)+E1 transitions linking states of the yrast and negative-parity bands at high spin and the presence of an additional even-spin, positive-parity band deexciting exclusively to the negative-parity sequence. The observations appear to be consistent with expectations based on the recently proposed concept of octupole phonon condensation.

description: This dissertation establishes the urgent political stakes of reading environmental poetry through queer epistemologies. The heteronormative visions of future life that often tacitly shape how we read environmental poems rely on patriarchal logics that offer limited resources for an ethics of living in our precarious material present. I argue that queer poets offer a rich archive for theorizing alternatives to these normative models of time and of anthropocentric life. In constellating the three discourses that animate my dissertation (ecocriticism, queer studies, and poetic theory) around shared theoretical questions regarding futurity, reproduction, and beyond-human relationality, I illustrate how contemporary environmental discourses regarding human reproduction and (non)human futures cannot be extricated from anti-racist and feminist interrogations of gender and sexuality. Through theoretically-situated close readings of formally-inventive poems, I articulate the significance of experimental and mixed-genre verse to a long history of American postwar ecopoetry. Contemporary queer poets use these experimental forms and structures, I argue, to reconceptualize time (as well as what it means to be human) by producing capacious models of agency and voice.

description: Biological membranes are capacitors that can be charged by applying a field across the membrane. The charges on the capacitor exert a force on the membrane that leads to electrostriction, i.e. a thinning of the membrane. Since the force is quadratic in voltage, negative and positive voltage have an identical influence on the physics of symmetric membranes. However, this is not the case for a membrane with an asymmetry leading to a permanent electric polarization. Positive and negative voltages of identical magnitude lead to different properties. Such an asymmetry can originate from a lipid composition that is different on the two monolayers of the membrane, or from membrane curvature. The latter effect is called 'flexoelectricity'. As a consequence of permanent polarization, the membrane capacitor is discharged at a voltage different from zero. This leads to interesting electrical phenomena such as outward or inward rectification of membrane permeability. Here, we introduce a generalized theoretical framework, that treats capacitance, polarization, flexoelectricity and piezoelectricity in the same language.

description: Praziquantel (PZQ) is a chiral class-II drug, and it is used as a racemate for the treatment of schistosomiasis. The knowledge of several cocrystals with dicarboxylic acids has prompted the realization of solid solutions of PZQ with both enantiomers of malic acid and tartaric acid. Here, the solid form landscape of such a six-component system has been investigated. In the process, two new cocrystals were structural-characterized and three non-stoichiometric, mixed crystal forms identified and isolated. Thermal and solubility analysis indicates a fourfold solubility advantage for the newly prepared solid solutions over the pure drug. In addition, a pharmacokinetic study was conducted in rats, which involved innovative mini-capsules for the oral administration of the solid samples. The available data indicate that the faster dissolution rate of the solid solutions translates in faster absorption of the drug and helps maintain a constant steady-state concentration.

description: Here we review the recent progress made in the detection, examination, characterisation and interpretation of oscillations manifesting in small-scale magnetic elements in the solar photosphere. This region of the Sun's atmosphere is especially dynamic, and importantly, permeated with an abundance of magnetic field concentrations. Such magnetic features can span diameters of hundreds to many tens of thousands of km, and are thus commonly referred to as the `building blocks' of the magnetic solar atmosphere. However, it is the smallest magnetic elements that have risen to the forefront of solar physics research in recent years. Structures, which include magnetic bright points, are often at the diffraction limit of even the largest of solar telescopes. Importantly, it is the improvements in facilities, instrumentation, imaging techniques and processing algorithms during recent years that have allowed researchers to examine the motions, dynamics and evolution of such features on the smallest spatial and temporal scales to date. It is clear that while these structures may demonstrate significant magnetic field strengths, their small sizes make them prone to the buffeting supplied by the ubiquitous surrounding convective plasma motions. Here, it is believed that magnetohydrodynamic waves can be induced, which propagate along the field lines, carrying energy upwards to the outermost extremities of the solar corona. Such wave phenomena can exist in a variety of guises, including fast and slow magneto-acoustic modes, in addition to Alfven waves. Coupled with rapid advancements in magnetohydrodynamic wave theory, we are now in an ideal position to thoroughly investigate how wave motion is generated in the solar photosphere, which oscillatory modes are most prevalent, and the role that these waves play in supplying energy to various layers of the solar atmosphere.

One dimensional lazy quantum walks and occupancy rate

description: Lazy quantum walks were presented by Andrew M. Childs to prove that the continuous-time quantum walk is a limit of the discrete-time quantum walk [Commun.Math.Phys.294,581-603(2010)]. In this paper, we discuss properties of lazy quantum walks. Our analysis shows that lazy quantum walks have $O(t^n)$ order of the n-th moment of the corresponding probability distribution, which is the same as that for normal quantum walks. Also, the lazy quantum walk with DFT (Discrete Fourier Transform) coin operator has a similar probability distribution concentrated interval to that of the normal Hadamard quantum walk. Most importantly, we introduce the concepts of occupancy number and occupancy rate to measure the extent to which the walk has a (relatively) high probability at every position in its range. We conclude that lazy quantum walks have a higher occupancy rate than other walks such as normal quantum walks, classical walks and lazy classical walks.
