description: Very metal-poor (VMP) stars (${\rm [Fe/H]}\leq -2$) that have sub-solar values of ${\rm [X/Fe]}$ for $α$ elements such as Mg, Si, and Ca, are referred to as $α$-poor VMP stars. They are quite rare among VMP stars and are thought to have formed from gas enriched predominantly by a single Type Ia supernovae (SN1a) in contrast to most VMP stars which are $α$-enhanced and usually associated with core-collapse supernovae. The observed abundance pattern in such stars can provide a direct way to probe the nucleosynthesis in individual SN1a. Although the abundance patterns in some $α$-poor VMP stars have been shown to be consistent with SN1a ejecta, a clear nucleosynthetic signature for SN1a resulting from the explosion of a near Chandrasekhar mass (near-${\rm M_{Ch}}$) or a sub-Chandrasekhar mass (sub-${\rm M_{Ch}}$) white dwarf, has not been unambiguously detected. We perform a detailed analysis of various formation channels of VMP stars and find that the $α$-poor VMP star SDSSJ0018-0939, which was earlier reported as a star with potential pair-instability supernova origin, provides almost a smoking-gun signature of a sub-${\rm M_{Ch}}$ SN1a resulting from He detonation. We find that compared to other $α$-poor VMP stars that were previously identified with SN1a, SDSSJ0018-0939 is the only star that has a clear and unambiguous signature of SN1a. Interestingly, our results are consistent with constraints on SN1a from recent galactic chemical evolution studies that indicate that sub-${\rm M_{Ch}}$ SN1a account for $\sim 50\hbox{--}75\,\%$ of all SN1a and are possibly the dominant channel in the early Galaxy.

description: Annual U. S. production of edible meat fats has been fairly stable since 1954 at around the 2.9-billion-pound rate. A steady increase in the output of edible beef fats during this period has about offset a slight decline in lard. Edible meat fats utilized in shortening have increased rapidly from 231 million pounds in 1954 to a record 959 million in 1963. In 1964, usage fell off to 851 million pounds but still accounted for one-third of all fats and oils consumed in shortening. Increased production of meat fat shortenings chiefly reflects improved technology and generally lower prices for raw materials.

description: Assessment and excavation in advance of road development revealed an area of occupation dating back to the Mesolithic and including a possible Neolithic to Early Bronze Age farmstead. A period of LIA to RB activity over four phases was also observed, probably indicating a small farm site that would have existed on the outskirts of Roman Godmanchester. Flint from the first two periods (Meso-Neo) was recovered, whilst pottery and burials, including an infant burial, amongst a network of ditches and enclosures marked the IA-RB period. An unusual bronze mount depicting a helmeted human head was also recovered, possibly AS in style.
Romano- British and medieval saltmaking and settlement in Parson Drove, Cambridgeshire

description: Proceedings of the Cambridge Antiquarian Society, 95, 25-48
description: Report on a site located in the silt fenland of Cambridgeshire, on the edge of a roddon, within an area studied in detail by the Fenland Project. The excavation revealed evidence for three phases of Romano-British rural settlement spanning the first to fourth centuries AD, associated with salt production and animal rearing. Medieval settlement did not begin until at least the twelfth century, the main period of activity was in the thirteenth to fourteenth centuries and, as in the Roman period, the layout and alignment of features appear to have been influenced by the existence of the roddon. Trackways and associated enclosures indicate the rearing of animals, and a series of pits and ditches provide further evidence for somewhat unusual, inland saltmaking. The surviving linear village plan of Parson Drove demonstrates its connection with the later medieval, post-reclamation planned landscape of this part of the Cambridgeshire fenland. A single ditch assigned to the fourteenth or fifteenth century probably reflects this later medieval phase, characterised by long droves and strip fields associated with the change from pastoral to arable agriculture.

It's Our Loss: No Privacy Amplification for Hidden State DP-SGD With Non-Convex Loss

description: Differentially Private Stochastic Gradient Descent (DP-SGD) is a popular iterative algorithm used to train machine learning models while formally guaranteeing the privacy of users. However, the privacy analysis of DP-SGD makes the unrealistic assumption that all intermediate iterates (aka internal state) of the algorithm are released since, in practice, only the final trained model, i.e., the final iterate of the algorithm is released. In this hidden state setting, prior work has provided tighter analyses, albeit only when the loss function is constrained, e.g., strongly convex and smooth or linear. On the other hand, the privacy leakage observed empirically from hidden state DP-SGD, even when using non-convex loss functions, suggests that there is in fact a gap between the theoretical privacy analysis and the privacy guarantees achieved in practice. Therefore, it remains an open question whether hidden state privacy amplification for DP-SGD is possible for all (possibly non-convex) loss functions in general.
 In this work, we design a counter-example and show, both theoretically and empirically, that a hidden state privacy amplification result for DP-SGD for all loss functions in general is not possible. By carefully constructing a loss function for DP-SGD, we show that for specific loss functions, the final iterate of DP-SGD alone leaks as much information as the sequence of all iterates combined. Furthermore, we empirically verify this result by evaluating the privacy leakage from the final iterate of DP-SGD with our loss function and show that this exactly matches the theoretical upper bound guaranteed by DP. Therefore, we show that the current privacy analysis for DP-SGD is tight for general loss functions and conclude that no privacy amplification is possible for DP-SGD in general for all (possibly non-convex) loss functions.

description: Cavity ring-down spectroscopy (CRDS) of single, optically manipulated aerosol particles affords quantitative retrieval of refractive indices for particles of fixed or evolving composition with high precision. Here, we quantify the accuracy with which refractive index determinations can be made by CRDS for single particles confined within the core of a Bessel laser beam and how that accuracy is degraded as the particle size is progressively reduced from the coarse mode (>1 μm radius) to the accumulation mode (<500 nm radius) regime. We apply generalized Lorenz–Mie theory to the intra-cavity standing wave to explore the effect of particle absorption on the distribution of extinction cross section determinations resulting from stochastic particle motion in the Bessel beam trap. The analysis provides an assessment of the accuracy with which the real, n, and imaginary, κ, components of the refractive index can be determined for a single aerosol particle.

description: I have critically reviewed the book entitled “The Next 100 Years: A Forecast for the 21st Century” written by George Friedman. The book contains chronically ordered thirteen chapters and 255 pages. For me, the book is somewhat unique that predicts about unforeseen future in this ever-dynamic era. Methodologically, the author used a combination of historical analogy, trend and geopolitical analyses. History, culture, technology, demography, economy, and strategic locations are the main variables for his forecasting. Even though I am not confident to say the authors’ work is scientific, it is not also simple black art. I prefer to review this book because it shed light on the next one-hundred year plan of the USA. As the world power, the activities of the USA affect Ethiopia directly or indirectly. Hereunder, I have summarized the main points of the book, followed by my own opinion.

Diese Forschungsrichtung, die auf dem Kontinent vernetzt ist, analysiert Konzepte wie hegemoniale Männlichkeit und männliche Militanz, Differenzen zwischen Männern und deren Bedeutung zur Erklärung von geschlechtsspezifischer Gewalt. Zunächst werden die Hintergründe der mangelnden Rezeption solcher Ansätze in Europa und in den USA erläutert, anschließend werden wesentliche Inhalte an Fallstudien skizziert. Der regionale Fokus liegt auf Südafrika und Uganda, da in beiden Ländern die Forschungen sehr breit gefächert, interdisziplinär, intersektional und innovativ sind. Auch die institutionelle Verankerung sowie die dabei zu bewältigenden Herausforderungen werden aufgezeigt. Zusammenfassend werden die Chancen für die deutschen Gender Studies durch einen verbesserten Austausch dargelegt.

description: We investigate the properties of accretion flows around the Konoplya-Zhidenko (KZ) black hole, which is proposed by deforming the Kerr metric with a single deformation parameter to test the no-hair theorem using gravitational wave observations. The dynamical equations describing the general relativistic viscous accreting flow are solved self-consistently to find the transonic accretion solutions in terms of global constants, such as energy ($E$), angular momentum ($\mathcal{L}$), viscosity parameter ($α$), spin ($a_{k}$), and deformation parameter ($η_0$). We obtain five distinct types of accretion solutions (O, A, $\text{A}^{\prime}$, W, and I-types), and observe that those solutions are not unique but rather continue to exist for wide range of parameter spaces in the $\mathcal{L}-E$ plane. Furthermore, we find that the viscous accretion flows can harbor shock waves when the relativistic shock conditions are satisfied. Consequently, the shock-induced global accretion solutions are obtained, and the effect of $η_0$ on shock properties, such as shock radius ($r_{\rm sh}$) and change in electron temperature ($T_{\rm e}$) across the shock front are investigated. Moreover, we calculate the spectral energy distributions (SEDs) of accretion flow using the relativistic thermal bremsstrahlung emission coefficient and study the modification of SEDs due to the increase of $η_0$ for both shock-induced and shock-free solutions. In addition, it has been noticed that the observable quantities, like quasi-periodic oscillation frequency ($ν_{\rm QPO}$) and bolometric disc luminosity ($L$), are strongly dependent on $η_0$. Finally, we phenomenologically show that the KZ black hole is consistent with the high-frequency QPOs, commonly observed in black hole binaries and black hole candidates.

description: The study investigates media regulatory bodies in Ethiopia. The research implemented a qualitative approach, mainly document analysis and in-depth interviews, whereby a purposive sampling technique was used to generate relevant data. The research finds out that more than 60 regulatory bodies, directly and indirectly, control Ethiopian media activities. The Ethiopian government established these media regulatory bodies (1991–2021). As a result, the tight control system of the Ethiopian media stems from an excessive number of regulations and regulatory bodies that have the power to control, shape, and inspect all media activities. The regulatory function prescribes the conditions that must be complied with to avoid unfair media practices and protect the government, audiences, and the public against the dangers inherent in such bad practices. In contrast, Media organizations' significant loss of independence due to the restrictive rules and regulatory bodies and journalists' self-censorship has increased. In the light of these measures, the Ethiopian media cannot ensure journalists' independence through institutional and professional accountability. As a result, media provide single-source and government-dominated information. The main recommendation of the research is that the government should suspend and revise the regulations of several regulatory bodies that discourage journalists and media houses from accessing freedom of speech and information. Therefore the government should change an unfriendly regulatory environment and a media model shift parallel with the public interest than the political economy interest.

Year: 2022

description: The purpose of this research is to assess the conservation and management of heritage and the existing status of tourism in the town of Debre Tabor and its environs. The town of Debre Tabor is one of the exceptional towns in Ethiopia with a rich historical heritage. The historical sites of the area (royal camps, temporary palace, and industrial center) have left the marks of attempts of civilizations and modernization. Nevertheless, these sites are not fully documented and their value for local development through tourism is not sustainably utilized. This paper, therefore, using intensive document review, observation, and semi-structured interview as methods of data acquisition and qualitative method as methods of data analysis tried to fill this missing. The research finding revealed that the three identified historical sites of the area are in a bad state of conservation. The main reason for this is largely laid on unwanted human intervention due to both lack of awareness and absences of well-trained professional in the area of heritage conservations. The impact of natural agents of destruction on the sites is not also trouble-free. Moreover, due to lack of promotion, negative perception of the community, and lack of infrastructure, the tourism potential of the sites is underexploited.

description: Using Internet in the academic arena empowers students to sharpen their skills and communication capabilities. However, internet Addiction (IA), characterized by an excessive use of time and resources affects their activities. This study uses mixed research design capturing data from students to access the impact of social media on academic achievement with particular emphasis on SMS usage, Internet addiction and the effect on their Cumulative Grade Point Average (CGPA). Key informant interviews and a questionnaire was designed and distributed to 422 randomly selected students. Descriptive and Inferential statistics (Multiple hierarchical regressions) were used to analyze the results. Results revealed that, 44.5% male and 27% female students are Internet Addicted. 65% of the students have Face book accounts, registered to more than one SMS’s. The highest majority, (82.8%) of students are using the internet at night time. However, 65% replied as they can balance their studies and Internet usage. The study discovered that students’ waste much of their time on SMS and expected that the more time they spent online the more addicted they become, and the lower is the time they spent on studying and achieving a good CGPA. However, the study found that Internet addiction does not significantly contributed beyond and above other factors on academic performance. Improvement in their CGPA may lay on other factors within the overall quality of education, the teaching-learning environment or other hidden attributes. Thus, students’ academic achievement is not highly attributed to the use of Internet and social media addiction.

Variously described in the past as Flemish, German, Swiss, or merely foreign, the six panels of stained glass are demonstrated to have been made in Cologne for one Godart Hauyser, a well-documented Hanseatic merchant who died c 1494. The panels were installed in Thorney Abbey Church in 1638 upon its restoration for the use of French and Dutch workers draining the local fens; however, it seems probable that the glass was originally set in the Hanseatic Steelyard of London, which was stripped between 1598 and 1606 and where Hauyser is known to have been active in mid-late 15th century.

description: This study analyzes the Structure, Conduct and Performance of Banking Sector in Ethiopia using balanced panel data of 10 years (2009-2018). The study also used the Random effect model for the Return on Asset (ROA) and fixed effect for Return on Equity (ROE) econometric model based on the Hausman model specification test. Accordingly, market concentration measure displayed that there was more concentration ratio in terms of asset, deposit , loan and advance in Ethiopia banking sector.The econometrics analysis results also revealed that bank specific factors such as Bank size, Loan to Deposit Ratio, Income Diversification, concentration and growth deposit are statistically significant and positively related in determining profitability of banks, whereas the cost- income ratio is statistically significant and negatively related with bank’s profitability. The study result also revealed that capital adequacy, loan to deposit ratio, concentration and market share (deposit) factors have positive and statistically significant relationship with Return on Equity (ROE). However, the cost - income ratio (CIR) has a negative and statistically significant relationship with Return on Equity (ROE). In general, the overall empirical findings provide evidence that the profitability of banks is mainly dominated by bank-specific factors which are in the hands of the management of the banks. So, the study suggests to the bank managers and policy makers to give high concern on the internal factors of profitability and set direction to manage the most dominant factors of performance.

description: (abridged)Photometric redshifts for AGN (galaxies hosting an accreting supermassive black hole in their center) are notoriously challenging and currently better computed via SED fitting, assuming that deep photometry for many wavelengths is available. However, for AGN detected all-sky, the photometry is limited and provided by different projects. This makes the task of homogenising the data challenging and is a dramatic drawback for the millions of AGN that wide surveys like SRG/eROSITA will detect. This work aims to compute reliable photometric redshifts for X-ray-detected AGN using only one dataset that covers a large area: the 10th Data Release of the Imaging Legacy Survey (LS10) for DESI. LS10 provides deep grizW1-W4 forced photometry within various apertures, thus avoids issues related to the cross-calibration of surveys. We present the results from CircleZ, a machine-learning algorithm based on a Fully Connected Neural Network. CircleZ uses training sample of 14,000 X-ray-detected AGN and utilizes multi-aperture photometry. The accuracy and the fraction of outliers reached in a test sample of 2913 AGN are 0.067 and 11.6%, respectively. The results are comparable to or better than those obtained previously for the same field but with much less effort. We further tested the stability of the results by computing the photometric redshifts for the sources detected in CSC2 and Chandra-COSMOS Legacy, reaching comparable accuracy as in eFEDS when limiting the magnitude of the counterparts with respect to the depth of LS10. The method applies to fainter samples of AGN using deeper optical data from future surveys (e.g., LSST, Euclid), granted LS10-like information on the light distribution beyond a morphological type is provided. With the paper, we release an updated version of the photometric redshifts (including errors and probability distribution function) for eROSITA/eFEDS.

description: In California, recreational fisheries contribute a significant amount to coastal economies, with pelagic and coastal pelagic species constituting a principal set of target species during summer and fall. Although traditional catch frequency (landings) data sets exist for these species, size-specific information is limited, especially for the largest size-classes. We digitized weekly records of trophy catch reported in the “Whoppers of the Week” section of the Western Outdoor News, a California fishing and hunting newspaper published since 1953. The resulting database contained catch records that described the largest fish caught at each sportfishing landing site along the California coast during 1966–2013. We then assessed the temporal dynamics in trophy size of the top-15 pelagic and coastal pelagic species, with a combined total of 21,440 individual catch records. Among the 15 pelagic and coastal pelagic species examined, the Yellowfin Tuna Thunnus albacares and Striped Bass Morone saxatilis were the only species that showed clear long-term declines in trophy size over the study period, whereas the Pacific Bluefin Tuna Thunnus orientalis, White Seabass Atractoscion nobilis, and Yellowtail Jack Seriola lalandi exhibited long-term increases in size. In general, the trophy sizes of pelagic species were more variable than those of coastal pelagic species and were not as consistently correlated with oceanographic conditions; both findings likely reflect the fact that oceanography drives the availability but not necessarily the size of pelagic species catch. In contrast, coastal pelagic species demonstrated trends in trophy sizes that were more consistently responsive to both oceanography and fisheries management. Our results suggest that oceanographic processes, natural history characteristics, fishing, and fisheries regulations each play a role in trophy size dynamics, but their relative influences vary among species.

In this work, Rydberg-atom graph gadgets are introduced to effectively program $K$-th order interactions within a Rydberg atom system. This approach facilitates the determination of the ground states of an Ising-type Hamiltonian, encoded to solve higher-order unconstrained optimization problems. A favorable scaling behavior, $O(N^K)$, is expected in terms of the number of atoms required for $N$-vertex hypergraph optimization problems.

To address this, we propose a novel fusion model that integrates three submodels: our proposed street-block graph neural network (SBGNet), a convolutional neural network (CNN) using ResNet-34, and a multi-layer perceptron (MLP). SBGNet represents urban street networks as graphs, with nodes as street blocks and geometric features as node attributes, while spatial arrangements serve as edge features. Topological and geometric features are extracted from this street-block representation. The CNN extracts visual features from monochrome images of the street network, and the MLP computes global descriptors using OSMnx and NetworkX to extract global features. Features from SBGNet, CNN, and MLP are concatenated and processed through a downstream MLP for classification. Experiments on a dataset of 6,700 samples from 12 major U.S. cities demonstrate that our fusion model significantly outperforms traditional methods, achieving a PR AUC of 0.88 ± 0.01, with improvements of 5% to 33% over baseline models, validating its effectiveness in classifying complex urban street networks.

description: In the light of earlier fieldwalking and aerial survey which had produced quantities of Roman pottery and indications of ditches and enclosures, exploratory work revealed more pottery and a cobbled surface. There are reports on `The pottery' (9--11), `Bronze objects (level III)' (11), `Iron objects' (11), and `The bones' by Anna Fernyhough (11--13). Two smaller investigations produced a patch of grey earth with some evidence of burnt wood, and coins. The whole is thought to represent a farmstead with a cobbled yard established after AD~175 and abandoned circa the early-fourth century AD. There were quantities of animal bone along with pottery wasters and iron slag nodules indicating a kiln and ironworking site somewhere in the vicinity.

description: Excerpts from the report: Traditionally, type 14 flue-cured tobacco produced in Georgia and Florida has been marketed untied, in round packs of loose leaves. Flue-cured tobacco marketed in other States is tied in bundles. There is substantial agreement among leaf buyers that the present method of selling looseleaf, flue-cured tobacco in cotton or burlap sheets is damaging to the leaf and that the packages thus handled present a poor appearance on the market. Tobacco growers can improve salability and decrease preparation cost by adopting a new form of looseleaf package, such as the one described here. The Department of Agriculture, in developing the new packaging method, established the following requirements: (1) The method should require no more labor on the part of the grower than is consistent with the needs of the auction. marketing system and modern processing technology. (2) The package should be open to rapid and easy inspection for foreign material at the auction market with a minimum of disarray. (3) The package should be square or rectangular to conserve space in transit and storage and to reduce unpacking labor at the processing conveyor. (4) The package should be adaptable to mechanized handling at the manufacturing plant and in marketing,

description: Two py-functionalized perylene bisimide ligands were synthesized and used to make bimetallic half-sandwich Ru(II) complexes. These were characterized by IR, 1H NMR, 13C CPMAS SSNMR spectroscopy, and elemental analysis. The complexes are wheel-and-axle (waa) compounds, where the axle is the divergent ligand and the wheels are the [(p-cymene)RuCl2] units. The complexes, but not the free ligands, showed absorption of volatile organic compounds such as toluene and xylenes through heterogeneous solid/gas uptakes. The reactivity is ascribable to the waa geometry, likely by an upset of the high stacking characterizing the crystalline frameworks of the free ligands. The kinetic profiles of the uptake reactions were determined.

description: We examine the effect of finite top- and bottom-quark masses on the Higgs production cross section in the gluon-gluon fusion channel. We employ both $\overline{\text{MS}}$ and on-shell renormalisation for the quark masses and provide a thorough comparison. Furthermore, we explore alternative treatments of quark masses, in particular in the four-flavour scheme, and investigate their impact on the cross section. Our work also presents novel predictions for differential cross sections in the Higgs rapidity. The results lead to a significant reduction of scale uncertainties, and our analysis enables us to offer well-grounded recommendations for future research in this area.

description: Proceedings of the Cambridge Antiquarian Society, 95, 49-56
description: In the early-twentieth century the excavator, F G Walker, interpreted the three prominent mounds known as Moulton Hills in Bourn, Cambridgeshire, as Roman burial mounds, rebuilt by a passing Danish army. His work is reviewed in the light of the new evidence derived from fieldwalking in the vicinity and re-examination of artefacts from the original excavation. The hypothesis is advance that the mounds are medieval earthworks constructed for the purpose of smelting iron.

A Romano- British temple complex and Anglo- Saxon burials at Gallows Hill, Swaffham Prior

description: Report on a Romano-British temple complex just southwest of Devil's Dyke and overlooking a Roman villa 1km away in Reach, to which the site appears linked by a trackway. The complex consisted of a main compound, defined by a palisade trench, containing three subsidiary areas: the large outer enclosure may represent a funerary precinct or temenos. Placed centrally within it is a rectangular area, itself subdivided, which, on the basis of cropmark evidence, contains a possible shrine or temple. To the north, post-dating the central enclosure, an internal double-ditched courtyard surrounds a circular feature and associated square structure, possibly a second shrine or temple. Within the third enclosure to the southwest a small single-celled building may represent another shrine or mausoleum. On the basis of artefactual evidence, the whole complex appears to have been short lived, the main focus being the first century and earlier half of the second century. The site was subsequently abandoned and was reused by Early Anglo-Saxons as a burial ground. An undated adult inhumation was found within demolition debris associated with the shrine/mausoleum located within the southwestern enclosure, while seven further inhumations were scattered across the investigation site. Two were identified as Anglo-Saxon on the basis of associated grave goods. The remaining graves were not excavated and may have been late Roman or Anglo-Saxon in date.

description: Precise millisecond pulsar (MSP) positions determined with very long baseline interferometry (VLBI) hold the key to building the connection between the kinematic and dynamic reference frames respectively used by VLBI and pulsar timing. The frame connection would provide an important pathway to examining the planetary ephemerides used in pulsar timing, and potentially enhancing the sensitivities of pulsar timing arrays used to detect stochastic gravitational-wave background at nano-Hz regime. We aim at significantly improving the VLBI-based MSP position from its current $\gtrsim1\,$mas precision level by reducing the two dominant components in the positional uncertainty -- the propagation-related uncertainty and the uncertainty resulting from the frequency-dependent core shifts of the reference sources. We introduce a new differential astrometry strategy of using multiple calibrators observed at several widely separated frequencies, which we call PINPT (Phase-screen Interpolation plus frequeNcy-dePendent core shifT correction; read as "pinpoint") for brevity. The strategy allows determination of the core-shift and mitigates the impact of residual delay in the atmosphere. We implemented the strategy on PSR J2222-0137, an MSP well constrained astrometrically with VLBI and pulsar timing. Using the PINPT strategy, we determined core shifts for 4 AGNs around PSR J2222-0137, and derived a VLBI-based pulsar position with uncertainty of 0.17 mas and 0.32 mas in right ascension and declination, respectively, approaching the uncertainty level of the best-determined timing-based MSP positions. The realization of the PINPT strategy promises a factor-of-5 positional precision enhancement (over conventional VLBI astrometry) for all kinds of compact radio sources observed at $\lesssim2$ GHz, including most fast radio bursts.
