description: Among the numerous factors that determine the level and structure of consumption, income is of the leading importance. It not only limits but also modulates consumption. For over 50 years, the Central Statistical Office (GUS) has been conducting household-based surveys on a regular basis. On the basis of the source results of those surveys, the coefficients of structure as well as the income regression and elasticity of income and savings have been calculated and analysed. Separate analyses have been carried out for three groups at different income levels: the poorer, the moderately rich and the wealthy households. The analyses showed that the disposal of income depends on its level. In the wealthier households, both the level and the proportion of savings are generally bigger, and the intensity of expenditure’s response to a growth of income is much smaller. Expenses disbursement for food generally have an average elasticity, but some, such as catering, fish, fruit, drinking water have a high flexibility. / Synopsis. Pośród licznych czynników warunkujących poziom i strukturę konsumpcji, wiodące znaczenie ma dochód. Jest on nie tylko czynnikiem limitującym konsumpcję, ale także modulującym ją. Od ponad 50 lat GUS prowadzi systematyczne badania budżetów gospodarstw domowych. Korzystając z źródłowych rezultatów tych badań obliczono i zanalizowano wskaźniki struktury oraz wskaźniki dochodowej regresji oraz elastyczności wydatków i oszczędności. Przeprowadzono analizy oddzielnie w trzech grupach różniących się poziomem dochodu; wyróżniono grupę uboższych, średnio zamożnych i zamożnych gospodarstw domowych. Analizy pokazały, że rozdysponowanie dochodu jest zależne od jego poziomu. W gospodarstwach zamożniejszych poziom jak i udział oszczędności są zasadniczo większe, zaś reakcje wydatków na wzrost dochodu są mniejsze. Wydatki żywnościowe ogólnie wykazują średnią elastyczność, ale niektóre, np. na gastronomię, ryby, owoce, wody pitne mają elastyczność wysoką.

description: If a community is unable to perform a needed public service by itself, it should explore the possibility of cooperating with other communities to provide that service. Small communities often do not have the money, personnel, or equipment to provide all needed public services on their own. Even if they can perform the function, they can often save considerable money and effort by cooperating with neighboring communities in providing some services. Cooperation can alleviate duplication, overlap, and fragmentation in the delivery of community services. It can lower costs to the individual communities in the process.
Improved Simulation of Quantum Circuits by Fewer Gaussian Eliminations

description: We show that the cost of strong simulation of quantum circuits using $t$ $T$ gate magic states exhibits non-trivial reductions on its upper bound for $t=1$, $t=2$, $t=3$, and $t=6$ with odd-prime-qudits. This agrees with previous numerical bounds found for qubits. We define simulation cost by the number of terms that require Gaussian elimination of a $t \times t$ matrix and so capture the cost of simulation methods that proceed by computing stabilizer inner products or evaluating quadratic Gauss sums. Prior numerical searchs for qubits were unable to converge beyond $t=7$. We effectively increase the space searched for these non-trivial reductions by $>10^{10^4}$ and extend the bounds to $t=14$ for qutrits. This is accomplished by using the Wigner-Weyl-Moyal formalism to algebraically find bounds instead of relying on numerics. We find a new reduction in the upper bound from the $12$-qutrit magic state of ${3^{\sim 0.469t}}$, which improves on the bound obtained from the $6$-qutrit magic state of ${3^{\sim 0.482t}}$.

description: The scalar-isoscalar, scalar-isotensor and vector-isovector pi-pi amplitudes are fitted simultaneously to experimental data and to Roy's equations. The resulting amplitudes are compared with those fitted only to experimental data. No additional constraints for the pi-pi threshold behaviour of the amplitudes are imposed. Threshold parameters are calculated for the amplitudes in the three waves. Spectrum of scalar mesons below 1.8 GeV is found from the analysis of the analytical structure of the fitted amplitudes.

description: The situation on the labour market in rural areas in the European Union is very diverse. There is visible disparity between the countries of Western Europe and Central and Eastern Europe previously undergoing transformation processes. This condition is mainly determined by demographic factors shaping the structure of the labour supply in rural areas. There are also important economic conditionings, creating the demand for labour, which can include, for example, labour productivity in agriculture, and employment opportunities outside agriculture. Not without significance there are also regional conditionings specifying particular areas, for example, their tourist attractiveness, or access of rural population to specific services and resources. / Synopsis. Sytuacja na rynku pracy na terenach wiejskich w krajach Unii Europejskiej jest bardzo zróżnicowana. Wyraźnie wyłania się dysproporcja pomiędzy krajami Europy Zachodniej i Środkowo-Wschodniej przechodzącymi uprzednio procesy transformacyjne. Stan ten determinowany jest głównie uwarunkowaniami demograficznymi kształtującymi strukturę podaży pracy na terenach wiejskich. Istotne są także czynniki ekonomiczne kreujące popyt na pracę, do których można na przykład zaliczyć wydajność pracy w rolnictwie, czy możliwości zatrudnienia poza rolnictwem. Nie bez znaczenia są także uwarunkowania regionalne poszczególnych obszarów określające, na przykład, ich atrakcyjność turystyczną, czy dostęp ludności wiejskiej do określonych usług i zasobów.

description: On January 28, 2021, the Confederation of Open Access Repositories (COAR) launched the COAR Notify Initiative. The aim is to develop and accelerate community adoption of a standard, interoperable, and decentralized approach to linking research outputs hosted in the distributed network of (data) repositories with resources from external service providers such as overlay-journals and open peer review services, using linked data notifications. In the presentation an overview will be provided with the technical challenges in current repositories and how decentralized solutions could have an impact on the current scholarly communication system. We will present the Event Notifications in Value-Adding Networks protocol which provides a network topology with data nodes and service nodes that inform each other about artifacts and services that are provisioned pertaining to artifacts. Using this protocol examples will be provided how this protocol can be used in various scholarly scenarios and relations with other projects that are implementing this protocol.

description: In these lectures we give a review of recent attempts to understand quantum gravity on de Sitter spaces. In particular, we discuss the holographic correspondence between de Sitter gravity and conformal field theories proposed by Hull and by Strominger, and how this may be reconciled with the finite-dimensional Hilbert space proposal by Banks and Fischler. Furthermore we review the no-go theorems that forbid an embedding of de Sitter spaces in string theory, and discuss how they can be circumvented. Finally, some curious issues concerning the thermal nature of de Sitter space are elucidated.

description: We consider the long-time limit of out-of-time-order correlators (OTOCs) in two classes of quantum lattice models with time evolution governed by local unitary quantum circuits and maximal butterfly velocity $v_{B} = 1$. Using a transfer matrix approach, we present analytic results for the long-time value of the OTOC on and inside the light cone. First, we consider `dual-unitary' circuits with various levels of ergodicity, including the integrable and non-integrable kicked Ising model, where we show exponential decay away from the light cone and relate both the decay rate and the long-time value to those of the correlation functions. Second, we consider a class of kicked XY models similar to the integrable kicked Ising model, again satisfying $v_{B}=1$, highlighting that maximal butterfly velocity is not exclusive to dual-unitary circuits.
The Qur'an and the Sunnah: The Foundations of Islamic Belief and Practice

description: The Qur'an and the Sunnah are the two primary sources of Islamic belief and practice. The Qur'an is the holy book of Islam, believed by Muslims to be the direct word of God as revealed to the Prophet Muhammad. The Sunnah is the collection of traditions and practices of the Prophet Muhammad, as recorded in hadith.The Qur'an and the Sunnah are foundational to all aspects of Islamic life, from religious beliefs and practices to social and political systems. The Qur'an and the Sunnah are also sources of inspiration and guidance for Muslims in their everyday lives. They teach Muslims how to live a good and moral life, and how to be kind and compassionate to others. The Qur'an and the Sunnah are the two primary sources of Islamic belief and practice. The Qur'an is believed by Muslims to be the literal word of God, revealed to the Prophet Muhammad through the angel Gabriel. The Sunnah is the collection of the Prophet Muhammad's sayings, deeds, and tacit approvals. Together, the Qur'an and the Sunnah provide Muslims with a comprehensive guide to how to live their lives in accordance with God's will.This book explores the Qur'an and the Sunnah in depth, examining their origins, their contents, and their significance for Muslims today. It begins by discussing the concept of revelation in Islam and the role of the Prophet Muhammad as a messenger from God. It then goes on to explore the major themes of the Qur'an, such as the oneness of God, the nature of prophecy, the afterlife, and Islamic law. The book also examines the Sunnah in detail, discussing its various types of reports and its methods of interpretation.

Reinforcement-learning control framework and sensing paradigm for flapping-wing micro aerial vehicles
Creators: name: Motamed, Mehran
Publisher: name: University of British Columbia
Year: 2010

description: Insects are fascinating for their maneuverability and complex aerobatics. Flapping-wing micro aerial vehicles are inspired from insect flight and aim to achieve high maneuverability at low speeds as well as hovering. Such a vehicle would have unique applications in social and economic sectors as well as in the military. This work, introduces a learning approach to flight control for flapping-wing micro aerial vehicles. A reinforcement-learning control framework has been proposed as a suitable biomimetic candidate for control of micro aerial vehicles. This work also discusses a matching sensing paradigm as a byproduct of the control approach. The control framework is then implemented using the Q-learning algorithm for the case study of lift generation for microflight. The results from a computer simulation using a quasi-steady aerodynamic model, and from an experimental investigation on a dynamically scaled model, confirm the applicability of the proposed framework. Moreover, the results of the learning scheme are shown to be comparable to a biological fruit fly, Drosophila melanogaster, in terms of the mean lift-force coefficient and the mean aerodynamic efficiency.

The current-voltage characteristics of the injecting contacts are extracted from the dependence of conductance on channel length. With reasonable parameters, a model of hopping injection into a disordered density of localized states, with emphasis on the primary injection event, agrees well with the field and the temperature dependence of the data over a broad range of temperatures and gate voltages.

description: Even though soyabeans production in Zambia is dominated by large farmers, getting increased yield to meet national requirements can only be achieved by increased participation of the teeming smallholders in soybeans cultivation. In the light of the recent increasing cultivation of soybeans by female farmers in the Eastern Province of Zambia, this study computed and compared profitability of male-owned and female-owned soyabeans farms. The specific objectives were to analyze gender dominance in cultivation activities, compare cost and returns, identify uses of profit and isolate factors affecting profit. The analytical tools used included descriptive statistics, Z-test and regression model. Summary statistics showed that 90.0% of male farmers was married while married female farmers constituted 73.3% of respondents. About 67.0% of male and 70.0% of female farmers attended and/or completed secondary school education. Male dominated land preparation (66.7%), produce transportation to market (65.0%) and weeding (56.7%) while females were dominant in planting (74.2%), shelling, (66.7%), bagging (71.7%) and marketing (82.0%). Quantity produced and profit were significantly higher for males while cost was higher for females. Male spent 57.7% of profit realised on purchase of household production assets like bicycles while female expended 63.3% of profit on foodstuffs consumed in the household. Expenditure by women was more household-centred compared with men. The variables influencing profit included formal education, extension visits, cost of transport, quantity of soybeans harvested and price. The major problems facing farmers included poor markets, low price and scarcity/high prices of inputs. It was concluded that men grew soybeans more profitably than women. It is recommended that extension services be tailored to women for enhanced profitability. Also, for its importance as a major protein source in the livestock industry, government needs to include soybeans among priority crops supported with inputs and purchased by the Food Reserves Agency to encourage increased cultivation and assure farmers of a ready market.

description: Plasmonic lattices consisting of nanoparticles in a homogeneous environment are well known fortheir support of so-called lattice plasmon resonances. They are associated with localized surfaceplasmons coupled to each other via free propagating photons along the structure. In this paper, weexplore modes in a stack of two identical plasmonic lattices. We demonstrate that such a structureis able to support a mode that is positioned strictly on a Rayleigh anomaly and does not shift withthe variation of distance between two lattices in wide limits. Given the fact that period is the moststably reproduced quantity in an experiment, such behavior can be used to simplify the fabricationof structures with resonances at desired energies.

description: The Zambian beef industry can potentially contribute more to the nation’s development if value addition is better promoted in the agricultural sector. Effective promotion of value chain (VC) activities is achievable only with in-depth understanding of economic activities embedded in the beef VC. This was the main issue for this study which analyzed cost incurred and margins secured across the value chain for smallholder beef cattle production in 4 districts of the Southern Province against the backdrop of high final consumer price of beef in Zambia. The objectives of the study were to describe the socio-economic characteristics of players, identify their value addition activities and how they influence the value chain, map the beef VC with key actors, compute the costs added to retail price at each value chain node and explain how this influences the final consumer price. Net margin accruing to VC participants and the overall cost of producing a unit of beef were also computed. Empirical results showed that the majority of VC participants were males which were below 50 years of age, married and had basic education. The cattle rearing node was found to contribute the largest proportion (38%) of the marketing margin of USD2.97/kg of beef followed by trading node and retailing node (27% apiece) while the abattoir node accounted for a paltry 8%. The net margin earned was also highest at the cattle rearing node (USD0.77/kg) followed by trading (USD0.70/kg), retailing (USD0.66/kg) and abattoir node (USD0.22/kg). Prices of steak and mixed cuts were found to be more uniform in all the four districts. However, the prices of offals tended to parity only in urban areas but were significantly higher in the largely rural Namwala District. In all the districts, the prices of offals were found to be significantly lower than those of steak and mixed cuts. It is concluded that final consumer prices are mostly determined by cost incurred and margins added at cattle rearing, trading and retailing nodes. Lastly, differentiating beef into steak and mixed cuts does not yield any corresponding price differentiation. The study recommended raising the participation of females in some value chain nodes, stopping beef differentiation into steak and mixed cuts and lowering final consumer prices by implementing policies such as elimination of double levies by councils that can lead to cost reduction at beef cattle rearing, trading and retailing nodes.

description: (ABRIDGED) Gaseous halos of nine nearby galaxies (with redshifts cz < 6000 km/s) were probed at large galactocentric radii using background quasars observed with HST GHRS and STIS. The projected quasar-galaxy separations range from 55 to 387 h^{-1}_{75} kpc. Lyαabsorption lines were successfully detected in the spectra of five quasars, at impact parameters of up to 170 h^{-1}_{75} kpc from the center of the nearby galaxy, and in each case at wavelengths consistent with the galaxy's redshift. Our observations include the lowest redshift Lyαlines detected to date. HI velocity fields were obtained at the VLA for three of the galaxies in our sample (and in one case was available from the literature), to derive their rotation curves. When comparing the inner rotation curves of the galaxies with the velocity at large radius provided by the Lyαline it is apparent that it is very difficult to explain the observed Lyαvelocity as due to gas in an extended rotating disk. In most cases one would need to invoke large warps in the outer gas disks and also thick gas disks in order to reconcile the observed velocities with the predicted ones. In light of these results we conclude that in a typical galaxy there is no longer detectable atomic gas corotating in an extended disk at radii > 35 α^{-1}, where α^{-1} is the stellar disk exponential scale-length. The cosmic web is the most likely origin for the detected Lyαlines.

description: Predicting click-through rate (CTR) is the core task of many ads online recommendation systems, which helps improve user experience and increase platform revenue. In this type of recommendation system, we often encounter two main problems: the joint usage of multi-page historical advertising data and the cold start of new ads. In this paper, we proposed GACE, a graph-based cross-page ads embedding generation method. It can warm up and generate the representation embedding of cold-start and existing ads across various pages. Specifically, we carefully build linkages and a weighted undirected graph model considering semantic and page-type attributes to guide the direction of feature fusion and generation. We designed a variational auto-encoding task as pre-training module and generated embedding representations for new and old ads based on this task. The results evaluated in the public dataset AliEC from RecBole and the real-world industry dataset from Alipay show that our GACE method is significantly superior to the SOTA method. In the online A/B test, the click-through rate on three real-world pages from Alipay has increased by 3.6%, 2.13%, and 3.02%, respectively. Especially in the cold-start task, the CTR increased by 9.96%, 7.51%, and 8.97%, respectively.

description: Collisionless plasma shocks are efficient sources of non-thermal particle acceleration in space and astrophysical systems. We use hybrid (kinetic ions -- fluid electrons) simulations to examine the non-linear feedback of the self-generated energetic particles (cosmic rays, CRs) on the shock hydrodynamics. When CR acceleration is efficient, we find evidence of both an upstream precursor, where the inflowing plasma is compressed and heated, and a downstream postcursor, where the energy flux in CRs and amplified magnetic fields play a dynamical role. For the first time, we assess how non-linear magnetic fluctuations in the postcursor preferentially travel away from the shock at roughly the local Alfvén speed with respect to the downstream plasma. The drift of both magnetic and CR energy with respect to the thermal plasma substantially increases the shock compression ratio with respect to the standard prediction, in particular exceeding 4 for strong shocks. Such modifications also have implications for the spectrum of the particles accelerated via diffusive shock acceleration, a significant result detailed in a companion paper, Caprioli, Haggerty & Blasi 2020, arXiv:2009.00007 [astro-ph.HE].

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Recently, the notion that the number of vacua is enormous has received increased attentions, which may be regarded as a possible anthropical explanation to incredible small cosmological constant. Further, a dynamical mechanisms to implement this possibility is required. We show in an operable model of cyclic universe that the universe can experience many cycles with different vacua, which is a generic behavior independent of the details of the model. This might provide a distinct dynamical approach to an anthropically favorable vacuum.

Publisher: name: Lusiadas Scientific Journal
Year: 2024

description: Introduction: The approach to chronic osteomyelitis is a challenge for orthopedic surgeon, despite the constant evolution of surgical techniques and antibiotics.


Methods: We report the case of a 66-year-old man diagnosed with chronic osteomyelitis of the right tibial shaft, an open fracture complication, with 37 years of evolution.


Results: After several attempts to control it with antibiotics and extraction of osteosynthesis material, the Papineau technique was performed in 2 stages, with exhaustive debridement, filling the dead space with cancellous iliac bone autograft, soft tissue coverage by second intention, with the aid of Vacuum-assisted closure and antibiotic therapy.


Conclusion: Various techniques have been described for the treatment of such devastating complication, with the Papineau method emerging as a viable and current option, despite its almost 50 years of existence, being the target of constant interest and modifications, following the evolution of medicine, aiming the best results.

description: Active metasurfaces promise reconfigurable optics with drastically improved compactness, ruggedness, manufacturability, and functionality compared to their traditional bulk counterparts. Optical phase change materials (O-PCMs) offer an appealing material solution for active metasurface devices with their large index contrast and nonvolatile switching characteristics. Here we report what we believe to be the first electrically reconfigurable nonvolatile metasurfaces based on O-PCMs. The O-PCM alloy used in the devices, Ge2Sb2Se4Te1 (GSST), uniquely combines giant non-volatile index modulation capability, broadband low optical loss, and a large reversible switching volume, enabling significantly enhanced light-matter interactions within the active O-PCM medium. Capitalizing on these favorable attributes, we demonstrated continuously tunable active metasurfaces with record half-octave spectral tuning range and large optical contrast of over 400%. We further prototyped a polarization-insensitive phase-gradient metasurface to realize dynamic optical beam steering.

description: Comment expliquer que l’utilisation des organismes génétiquement modifiés (OGM) dans l’agriculture et l’alimentation pose problème en France où ils ne sont pratiquement pas utilisés et semble aller de soi aux États-Unis, où ils le sont à grande échelle ? Selon certains, les consommateurs américains ont accepté les aliments transgéniques, du fait d’une différence d’attitude à l’égard des risques, de l’alimentation et de la nature. Rejetant cette explication, cet article présente une analyse comparée de la trajectoire des OGM comme problème public en France et aux États-Unis. Il démontre que les arguments très similaires sont mis en avant par les opposants et protagonistes se focalisent sur les mêmes zones de conflits. Mais alors qu’en France (et plus largement en Europe), les arguments des opposants « cristallisent » au cours d’épreuves spécifiques et contribuent à la définition des dimensions cognitives et normatives des OGM comme problème public, cette «cristallisation » n’a pas lieu aux États-Unis. Trois facteurs semblent expliquer cette différence : (i) les choix réglementaires très différents réalisés en 1990 ; (ii) le fait que l’utilité des plantes transgéniques est mal perçue en France alors que leur assimilation avec le projet d’une agriculture intensive et exportatrice est perçue positivement aux États-Unis ; (iii) l’influence grandissante d’un cadre plus large et «constructiviste » pour l’analyse des risques en Europe, alors qu’aux États-Unis les instances réglementaires continuent à fonder leur légitimité sur la « sound science ».
A theoretical description of energy spectra and two-neutron separation energies for neutron-rich zirconium isotopes

description: Very recently the atomic masses of neutron-rich Zr isotopes, from $^{96}$Zr to $^{104}$Zr, have been measured with high precision. Using a schematic Interacting Boson Model (IBM) Hamiltonian, the evolution from spherical to deformed shapes along the chain of Zr isotopes, describing at the same time the excitation energies as well as the two-neutron separation energies, can be rather well reproduced. The interplay between phase transitions and configuration mixing of intruder excitations in this mass region is succinctly addressed.

description: Fresh fish is traditionally consumed in Spain and it is part of the Mediterranean diet. The aim of this work is to study the consumers' preference toward fresh fish sold in trays and in countertop, in the city of Zaragoza (Spain). The major part of respondents had consumed fresh fish at least once a week and they buy it in the countertop. Fishes in trays are considered as most hygienic, with better conservation and easier to buy. Freshness is fundamental for fishes taste. Consumers perceive fish sold at countertop is fresher than fish conditioner in trays. Fish date capture, in addition of its expiration date, may influence the perception of fish quality as well. The packaging of a freshly caught fish may have a positive impact on consumer purchasing decision while a long term caught fish - although without a expired date - may have negative influence on consumer product evaluation.
Calculation of Optical Response Functions of Dilute-N GaPAsN Lattice-matched to Si

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Dilute-N GaPAsN alloys have great potential for optoelectronics lattice-matched to Si. However, there is a lack of systematic calculation of the optical response of these alloys. The present paper uses the sp^3d^5s^*s_N tight-binding model to calculate the fullband electronic structure of dilute-N GaPAsN, and then calculate the optical response functions considering direct transitions within the electric dipole approximation. Good agreement is obtained for the dielectric function in comparison to available optical data for dilute nitrides. To achieve this, the sp^3d^5s^* parameters for GaP and GaAs are optimized for their optical properties in comparison to published data, which are then used as the basis for the sp^3d^5s^*s_N parameters for dilute-N GaPN and GaAsN. The calculated absorption between the valence band and the newly formed lowest conduction band of the dilute nitrides increases as the N fraction increases, in agreement with experiments, mainly due to the net increase in their coupling in the entire Brillouin zone, supported by the calculated momentum matrix element in the present work.

The purpose of the study was to identify strategies that could serve as a basis of the selection and development of municipal projects aimed at boosting the Sugarcane Development in the region. Focus groups with different stakeholders such as growers, entrepreneurs, distributors, and experts in the field were conducted. Different tools were applied that led a diagnosis and conclude, besides the generation of strategic lines, that sugarcane is a mainstay of economic development that needs to envolve from a bussines perspective and explore new potencial markets, prior to that, balance the force of the producers who are the weakest link in the chain. In order to accomplish the above, it will be needed the participation of all the chain elements, prior to that, balance the force of the producers who are the weakest link in the chain. Implications such as the need to empower the producers and involve all the elements of the value chain are discussed.

description: Finding analytically the statistics of the longest common subsequence (LCS) of a pair of random sequences drawn from c alphabets is a challenging problem in computational evolutionary biology. We present exact asymptotic results for the distribution of the LCS in a simpler, yet nontrivial, variant of the original model called the Bernoulli matching (BM) model which reduces to the original model in the large c limit. We show that in the BM model, for all c, the distribution of the asymptotic length of the LCS, suitably scaled, is identical to the Tracy-Widom distribution of the largest eigenvalue of a random matrix whose entries are drawn from a Gaussian unitary ensemble. In particular, in the large c limit, this provides an exact expression for the asymptotic length distribution in the original LCS problem.
