Armenian genocide survivors: Adaptation and adjustment eight decades after massive trauma
Creators: name: Kupelian, Diane Louise

description: Armenian survivors of the 1915-1923 genocide committed by the Turkish government against the Armenians and other Christian minorities in Turkey were compared to a control group of elderly Armenians who did not experience the genocide. Both groups were assessed for symptoms of post-traumatic stress disorder (PSTD) via the Structured Clinical Interview for DSM-III-R (SCID) - PTSD module, and for current adaptation via the Tennessee Self-Concept Scale (TSCS), the Life Satisfaction Scale (LSI), and the Brief Symptom Inventory (BSI). In addition, both groups were assessed for post-traumatic reactions to recent news of anti-Armenian violence from Turkic Azeris via the Impact of Event Scale (IES). By assessment with the SCID, 3 of 34 survivors and 0 of 34 control subjects were diagnosed with PTSD. Although both groups were equally unlikely to have PTSD, the survivor group had significantly more positive symptoms of PTSD than the control group. This confirms the hypothesis that PTSD symptoms would linger, even eight decades, and therefore be higher in survivors than controls. PTSD symptoms, past and present, were further examined by type of symptom. Survivors met criteria for significantly more present intrusion symptoms, and tended to report more avoidance symptoms. In the past, avoidance symptoms were significantly higher for survivors than control subjects. Between group differences were found on one of three global BSI scales, with control subjects unexpectedly reporting a greater number of symptoms. No between group differences were found on the Total TSCS, LSI, or IES, indicating that, contrary to hypothesis, survivors had a similar sense of life satisfaction and self-esteem, and were not more sensitized to current anti-Armenian violence than controls. These assessments indicate that survivors had adjusted as well as the control group, despite their higher trauma symptomatology. An unexpected finding was an indication of higher pathology on the BSI and the somatic category of PTSD symptoms among those controls who were the grandchildren of survivors from earlier pogroms, as compared to other controls. Conclusions are that post-traumatic stress symptomatology can continue eight decades, as evidenced in the survivor group, but that, overall, this survivor sample appears to have adjusted as well as a control sample of elderly Armenians.

description: Andrena (Onagrandrena) blaisdelli Cockerell, 1924
[Holotype: CASC; ♀ San Diego, California, US; May 30, 1980]
This species is a pollen specialist on plants in the genus Camissonia Link (LaBerge & Thorp 2005). It occurs in California, USA and BC, Mexico (LaBerge & Thorp 2005). We reviewed one specimen reported by LaBerge & Thorp (2005) collected in March 1961 in La Zapopita, Valle de La Trinidad in the Chaparral region (LACM). The BBPT collected 2 females in Coastal Sage Matorral in May 2022 (MABC). See fig. 16.

description: We study q-stars with various symmetries in anti de Sitter spacetime in 3+1 dimensions. Comparing with the case of flat spacetime, we find that the value of the field at the center of the soliton is larger when the other parameters show a more complicated behavior. We also investigate their phase space when the symmetry is local and the effect of the charge to its stability.

Estimating the single-photon projection of low-intensity light sources

description: Estimating the quality of a single-photon source is crucial for its use in quantum technologies. The standard test for semiconductor sources is a value of the second-order correlation function of the emitted field below $1/2$ at zero time-delay. This criterion alone provides no information regarding the amplitude of the single-photon contribution for general quantum states. Addressing this question requires the knowledge of additional observables. We derive an effective second-order correlation function, strongly connected to the Mandel-$Q$ parameter and given in terms of both the second-order correlation and the average photon number, that provides a lower bound on the single-to-multi-photon projection ratio. Using both observables individually allows for lower and upper bounds for the single-photon projection. Comparing the tightness of our bounds with those in the literature, we find that relative bounds may be better described using the average photon number, while absolute bounds for low excitation states are tighter using the vacuum projection. Our results show that estimating the quality of a single-photon source based on additional information is very much dependent on what aspect of the quantum state of light one is interested in.

description: Online hate speech has been a topic of public concern and research interest for some time. Initially the focus of this centred on the proliferation of online groups and websites promoting and distributing discriminatory content. Since the introduction of more interactive tools and platforms in the mid-2000s that enabled new and faster ways of disseminating content in a relatively anonymous fashion, concerns about online hate speech becoming a pervasive behavior have increased.

Current research and analysis acknowledge the complex nature of online hate, the mediating role of technology and the influence of other contextual factors (e.g. social or political events). However, despite the growing attention on the topic, New Zealand-based research looking at personal experiences and/or exposure to online hate is surprisingly absent. This study seeks to address this gap. It builds on existing international research on young people’s experiences to explore those of the adult New Zealand population based on a nationally representative sample. The research instrument used for this study was an online survey. The survey was administered by Colmar Brunton in June 2018. The maximum margin of error for the whole population is ±3.1% at the 95% confidence level. The sample is representative of the wider population on key demographics: age, gender, ethnicity, and location.

description: Solid-state magnetometers like the Nitrogen-Vacancy center in diamond have been of paramount importance for the development of quantum sensing with nanoscale spatial resolution. The basic protocol is a Ramsey sequence, that imprints an external static magnetic field into phase of the quantum sensor, which is subsequently readout. In this work we show that the hyperfine coupling between the Nitrogen-Vacancy and a nearby Carbon-13 can be used to set a post-selection protocol that leads to an enhancement of the sensitivity under realistic experimental conditions. We found that for an isotopically purified sample the detection of weak magnetic fields in the $μ$T range can be achieved with a sensitivity of few nTHz$^{-1/2}$ at cryogenic temperature ($4$ K), and $0.1$ $μ$THz$^{-1/2}$ at room temperature.

 Remarks: H. punctulatissimus was previously known only from Konya. With the present study six further provinces are added to its known distribution. It is recorded for the first time from the regions East Anatolia and Mediterranean. In Turkey the distribution of this taxon is mainly limited to eastern and central Anatolia. It is a species of open land and mountains that is recorded above 900 m and occurs more frequently at about 1200 m altitude. Interestingly, it has not been found in Erzurum since the 1970s, despite intensive collection work. Another remarkable thing: The abundance is very low, except for Antalya, each province is only represented by one sample. The flight period lasts from the end of May to July, with a peak in June. It is moderately collected in Turkey (8 provinces).
 Distribution: Western Palaearctic. In Turkey: Konya (WARNCKE 1972), Ağrı, Antalya, Kars, Kayseri, Nevşehir, Niğde, Van.

description: We study the magnetic and superconducting proximity effects in a semiconducting nanowire (NW) attached to superconducting leads and a ferromagnetic insulator (FI). We show that a sizable equilibrium spin polarization arises in the NW due to the interplay between the superconducting correlations and the exchange field in the FI. The resulting magnetization has a nonlocal contribution that spreads in the NW over the superconducting coherence length and is opposite in sign to the local spin polarization induced by the magnetic proximity effect in the normal state. For a Josephson-junction setup, we show that the nonlocal magnetization can be controlled by the superconducting phase bias across the junction. Our findings are relevant for the implementation of Majorana bound states in state-of-the-art hybrid structures.

Polarization as a tuning parameter for Floquet engineering: magnetism in the honeycomb, square, and triangular Mott insulators

description: Magnetic exchange couplings can be tuned by coupling to periodic light, where the frequency and amplitude are typically varied: a process known as Floquet engineering. The polarization of the light is also important, and in this paper, we show how different polarizations, including several types of unpolarized light, can tune the exchange couplings in distinct ways. Using unpolarized light, for example, it is possible to tune the material without breaking either time-reversal or any lattice symmetries. To illustrate these effects generically, we consider single-band Hubbard models at half-filling on the honeycomb, square and triangular lattices. We derive the effective Heisenberg spin models to fourth order in perturbation theory for arbitrary fixed polarizations, and several types of unpolarized light that preserve time-reversal and lattice symmetries. Coupling these models to periodic light tunes first, second and third neighbor exchange couplings, as well as ring exchange terms on the square and triangular lattices. Circularly polarized light induces chiral fields for the honeycomb and triangular lattices, which favors non-coplanar magnetism and potential chiral spin liquids. We discuss how to maximize the enhancement of the couplings without inducing heating.

description: Recent results from DESI combined with cosmic microwave background data give the tightest constraints on the sum of neutrino masses to date. However, these analyses approximate the neutrino mass hierarchy by three degenerate-mass (DM) neutrinos, instead of the normal (NH) and inverted hierarchies (IH) informed by terrestrial neutrino oscillation experiments. Given the stringency of the upper limits from DESI data, we test explicitly whether the inferred neutrino constraints are robust to the choice of neutrino mass ordering using both Bayesian and frequentist methods. For Planck data alone, we find that the DM hierarchy presents a good approximation to the physically motivated hierarchies while showing a strong dependence on the assumed lower bound of the prior, confirming previous studies. For the combined Planck and DESI baryon acoustic oscillation data, we find that assuming NH ($M_\mathrm{tot} < 0.13\,\mathrm{eV}$) or IH ($M_\mathrm{tot} < 0.16\,\mathrm{eV}$) loosens the Bayesian upper limits compared to the DM approximation ($M_\mathrm{tot} < 0.086\,\mathrm{eV}$). The frequentist analysis shows that the different neutrino models fit the data equally well and the loosening of the constraints can thus be attributed to the lower bounds induced by NH and IH. Overall, we find that the DM hierarchy presents a good approximation to the physically motivated hierarchies also for Planck+DESI data as long as the corresponding lower neutrino mass bounds are imposed.

description: In the first Born approximation and using an elliptically polarized laser field, the Mott scattering of an electron by a Coulomb potential is investigated using the Dirac-Volkov states to describe the incident and scattered electrons. The results obtained are compared with the results of S.M. Li \textit{et al} \cite{1} for the case of a linearly polarized laser field and with the results of Y. Attaourti \textit{et al} \cite{2} for the case of a circular polarization.

description: Recommendation systems are highly interested in technology companies nowadays. The businesses are constantly growing users and products, causing the number of users and items to continuously increase over time, to very large numbers. Traditional recommendation algorithms with complexity dependent on the number of users and items make them difficult to adapt to the industrial environment. In this paper, we introduce a new method applying graph neural networks with a contrastive learning framework in extracting user preferences. We incorporate a soft clustering architecture that significantly reduces the computational cost of the inference process. Experiments show that the model is able to learn user preferences with low computational cost in both training and prediction phases. At the same time, the model gives a very good accuracy. We call this architecture EfficientRec with the implication of model compactness and the ability to scale to unlimited users and products.

description: We present experimental results on crystal--amorphous transition of forsterite (Mg2SiO4) silicate under ion irradiation. The aim of this work is to study the structural evolution of one of the most abundant crystalline silicates observed in space driven by ion irradiation. To this aim, forsterite films have been sythesised in laboratory and irradiated with low energy (30--60 keV) ion beams. Structural changes during irradiation with H+, He+, C+, and Ar++ have been observed and monitored by infrared spectroscopy. The fraction of crystalline forsterite converted into amorphous is a function of the energy deposited by nuclear collision by ions in the target. Laboratory results indicate that ion irradiation is a mechanism potentially active in space for the amorphisation of silicates. Physical properties obtained in this work can be used to model the evolution of silicate grains during their life cycle from evolved stars, through different interstellar environments and up to be incorporated in Solar System objects.

description: We say that a graph G is Class 0 if its pebbling number is exactly equal to its number of vertices. For a positive integer d, let k(d) denote the least positive integer so that every graph G with diameter at most d and connectivity at least k(d) is Class 0. The existence of the function k was conjectured by Clarke, Hochberg and Hurlbert, who showed that if the function k exists, then it must satisfy k(d)=Ω(2^d/d). In this note, we show that k exists and satisfies k(d)=O(2^{2d}). We also apply this result to improve the upper bound on the random graph threshold of the Class 0 property.

description: We study the conditions for convective instability in rotating, non-magnetic proto--neutron stars. The criteria that determine stability of nascent neutron stars are analogous to the Solberg--Hoiland conditions but including the presence of lepton gradients. Our results show that, for standard angular velocity profiles, convectively unstable modes with wave-vectors parallel to the rotation axis are suppressed by a stable angular momentum profile, while unstable modes with wave-vectors perpendicular to the axis remain unaltered. Since the wave-vector is perpendicular to the velocity perturbation, the directional selection of the unstable modes may result in fluid motions along the direction of the rotation axis. This occurs in rigidly rotating stars as well as in the inner core of differentially rotating stars. Our results provide a natural source of asymmetry for proto--neutron stars with the only requirement that angular velocities be of the order of the convective characteristic frequency.

description: \begin{abstract} In this Letter we follow the asymptotic spatial correlation of buildings' heights $G_{\infty}(r)$ in the whole of the Netherlands \cite{bag3d}, which comprises $\approx 10,000,000$ buildings, for the purpose of recovering its scaling with respect to space and time given respectively by the exponents $r^{2 α}$ and $t^{2β}$. This allows us to identify the universality class of the evolution of the urban skyline seen as a dynamically evolving interface. Two major classes of cities were identified based on the recovered value of $α=0.4$ and $α= 0$, which correspond respectively to the KPZ and the EW universality classes. Picking a discrete model from each of these classes and mapping it to physical rules for constructions in cities we conclude that imposed restrictions on buildings' heights are reflected in the exponent $α$ and thus have implications on how the skyline evolves.

description: This study has been undertaken to investigate water permeability characteristics of thin cement composites containing various recycled aggregate viz., recycled concrete, stone, brick and wood chips. Thin panels of 290mmx95mmx20mm size were cast with three different mixes incorporating three volume fractions of 20%, 30% and 40% of aggregate to determine the permeability coefficient of cement composites. Cumulative amount of water flowing through the test specimen was plotted against time which showed that the steady state condition was reached after three days. It has been found that the coefficient of permeability was increased with the increase in volume fraction of rebycled aggregate of all varieties. It was also revealed that the coefficient of permeability was higher for cement composite with light-weight recycled aggregate. Regression analysis was carried out on the experimental data to develop relationship among the coefficient of permeability and volume fraction of recycled aggregate. The relationships between coefficient of permeability and unit weight of cement composites have also been presented and discussed.

description: A new and successful attack strategy in neural cryptography is presented. The neural cryptosystem, based on synchronization of neural networks by mutual learning, has been recently shown to be secure under different attack strategies. The advanced attacker presented here, named the ``Majority-Flipping Attacker'', is the first whose success does not decay with the parameters of the model. This new attacker's outstanding success is due to its using a group of attackers which cooperate throughout the synchronization process, unlike any other attack strategy known. An analytical description of this attack is also presented, and fits the results of simulations.

description: Floquet engineering is a powerful tool that drives materials with periodic light. Traditionally, the light is monochromatic, with amplitude, frequency, and polarization varied. We introduce Floquet engineering via unpolarized light built from quasi-monochromatic light, and show how it can modify strongly correlated systems, while preserving the original symmetries. Different types of unpolarized light can realize different strongly correlated phases As an example, we treat insulating magnetic materials on a triangular lattice and show how unpolarized light can induce a Dirac spin liquid.

description: The present study is an attempt to familiarize ferrocement technology for the construction of low-cost structures for farm uses. The selected structures that have been identified for farm uses are storage structure, cattle trough, irrigation and drainage canal lining, and manhole cover. Utilizing locally available materials the design and fabrication of the structures have been made using .simple techniques. The cost of construction of ferrocement structures has also been estimated on the basis of present cost of materials and labour. It is hoped that the observations made in this study will bring new idea in achieving wide acceptance of this technology for the construction of low-cost structures for farm uses.

description: The productivity of a crop depends on genotype x environment interaction. Temperature and light influence various physiological processes including photosynthesis and respiration; and consequently the rate and duration of growth and thus the productivity of wheat. Investigation was made on the photothermal unit requirement of the newly released wheat variety `Satabdhr under different irrigation regimes. Full irrigated wheat required more days for onset, duration and thermal units for expression of various phenophases or for maturity than that of non-irrigated one; but almost similar of the units within the treatments irrigated at 2 or 3 stages. A relatively fixed amount of heat units was needed to proceed from one phenophase to the other or sowing to maturity, irrespective of the sowing date studied. The 'growing-degree days' (GDD) and 'crop heat unit' (CHU) indices were found superior to other units in explaining wheat maturity. Heat use efficiency for production of seed yield and total dry matter production was evaluated. The highest heat use efficiency (2.26 and 6.66 kg/ha/deg.-day for seed yield and dry-matter, respectively) were obtained in well irrigated treatment, and the lowest (1.14 kg/ha/deg.- • day) in full deficit treatment.
Macroeconometric evaluation of Indian trade policy: Structural sensitivity, stochastic dynamics and nonlinear optimal control
Creators: name: Varma, Sona
Publisher: name: American University
Year: 2023

description: This dissertation investigates the effects of policy reform on the Indian trade sector over the period 1970 to 1985. The model used in this study is a multisectoral model that specifies the trade, monetary, and output sectors of the Indian economy. The model is estimated using limited and full information methods. Simulation and optimal control are used for policy analysis. India faced a severe economic crisis in 1990/91. Foreign exchange reserves were depleted. Fiscal deficit and federal debt levels were at record high. Most macroeconomic indicators pointed to an economy on the brink of collapse. The Government of India obtained several short and medium-term loans from the International Monetary Fund and the World Bank to alleviate the crisis. The Government also implemented a series of policy measures to stabilize and restructure the economy. These included reforms in the trade sector, efforts to contain the fiscal deficit, and tight credit policies to reduce inflation. There is considerable controversy among Indian economists regarding the impact of these policy changes on long term economic performance. This study examines the effects of policy reform on the Indian trade sector, its repercussions on the domestic economy, and the welfare costs associated with such policies in restoring stability and future economic growth. Simulation and control theory are now well established in the economics profession. Simulation is used to examine the effects of exchange rate, monetary, and fiscal policy changes on various sectors of the economy. Control techniques are used to obtain optimal policies given economic targets, quantify the tradeoffs between alternative policy choices, and evaluate the welfare costs associated with various policy regimes. The study concludes that trade policy reform has significant and enduring effects on the monetary and output sectors. It also establishes the use of control theory in providing guidelines for policy formulation using the concept of welfare maximization.

description: The study was conducted to investigate the consumption level, income elasticities and buying behavior of fish in Dhaka city. The required primary data were collected from 75 households during March 2004 in Dhaka city through purposive sampling method. Monthly per capita consumption of different types of fishes increased with the increase of monthly income. The amount of fish consumption increased more than two times from lower income group to higher income group except kechki (Corea soboma) and mola (Amblapharyngodon mola). These types of fishes were more consumed by lower income group. For this, monthly per capita expenditure percentage decreased with the increase of monthly income except above types of fishes. Most of the fishes were found as a normaVluxury item. Shole (Channa striatus), lati (Channa punctatus) and mola (Amblapharyngodon moia) were found as inferior fish items. Fifty six percent of the households preferred to buy fish in the early morning, 32 percent in the late morning, 13 percent in the evening, 11 percent in the afternoon and 5 percent at noon. The general law of demand was applicable in the study area; that means when the price of fish rose or fell, consumers reduced or increased the consumption of fish. Freshness and taste were found the most important factor for purchasing fish. The households in the studied area for purchasing fish rarely considered the factor cholesterol level. Illish (Hilsha illisha) was found highly preferable and shrimp was found moderately preferable fish for both male and female groups.

description: In earlier work, we analyzed the impossibility of codimension-one collapse for surfaces of negative Euler characteristic under the condition of a lower bound for the Gaussian curvature. Here we show that, under similar conditions, the torus cannot collapse to a segment. Unlike the torus, the Klein bottle can collapse to a segment; we show that in such a situation, the loops in a short basis for homology must stay a uniform distance apart.
