Reactive coupling can beat the motional quantum limit of nanowaveguides coupled to a microdisk resonator

Dissipation is generally thought to affect the quantum nature of the system in an adverse manner; however, we show that dissipatively coupled nanosystems can be prepared in states which beat the standard quantum limit of the mechanical motion. We show that the reactive coupling between the waveguide and the microdisk resonator can generate the squeezing of the waveguide by injecting a quantum field and laser into the resonator through the waveguide. The waveguide can show about 70-75% of maximal squeezing for temperature about 1-10 mK. The maximum squeezing can be achieved with an incident pump power of only 12 {mu}W for a temperature of about 1 mK. Even for temperatures of 20 mK, achievable by dilution refrigerators, the maximum squeezing is about 60%.
Optomechanics in an ultrahigh-Q two-dimensional photonic crystal cavity

We demonstrate an ultrahigh-Q slotted two-dimensional photonic crystal cavity capable of obtaining strong interaction between the internal light field and the mechanical motion of the slotted structure. The measured optical quality factor is Q = 1.2×10^6 for a cavity with an effective modal volume of V_(eff) = 0.04(λ)^3. Optical transduction of the thermal motion of the fundamental in-plane mechanical resonance of the structure (ν_m = 151 MHz) is performed, from which a zero-point motion optomechanical coupling rate of g∗/2π = 320 kHz is inferred. Dynamical back-action of the optical field on the mechanical motion, resulting in cooling and amplication of the mechanical motion, is also demonstrated.

: The unweighted $k-edge-conneCt \dot{i}v\dot{i}ty$ augmentation problem ( $k \mathrm{E}\mathrm{C}\mathrm{A}$ for short) is de-ﬁned by ” Given a $ \sigma$ -edge-connected graph $G=(V, E)$ , ﬁnd an edge set $E’$ of minimum cardinality such that $G’=(V, E \cup E’)$ is $( \sigma+\delta)$ -edge-connected and $ \sigma+\delta=k$ ”, where $E’$ is called a solution to the problem. Let $k \mathrm{E}\mathrm{C}\mathrm{A}(\mathrm{s},\mathrm{s}\mathrm{A})$ denote $k \mathrm{E}\mathrm{C}\mathrm{A}$ such that both $G$ and $G’$ are simple. The subject of the present paper is $( \sigma+1)\mathrm{E}\mathrm{C}\mathrm{A}(\mathrm{S},\mathrm{s}\mathrm{A})$ (or $k \mathrm{E}\mathrm{C}\mathrm{A}(\mathrm{s},\mathrm{s}\mathrm{A})$ with $k= \sigma+1$ ). Let $ \mathcal{M}$ be any maximum matching of a certain graph $R(G)$ whose vertex set $V _{R}$ consists of vertices representing all leaves of $G$ . From $ \mathcal{M}$ we obtain an edge set $E _{0}’$ , with $ |E_{0}’|=|\mathcal{M}|$ , such that each edge connects vertices in distinct leaves of $G$ . Let $ \mathcal{L}_{1}$ be the set of lea.v es to be created by adding $E _{0}’\mathrm{t}\mathrm{o}G$ , and $ \mathcal{K}_{1}$ the set of remaining leaves of $G$ . The main result is to propose two $
Multiple frequency fault detection, correction and identification of vibration forces on the rotor of a rotational active magnetic bearing system

In this paper, the authors propose a real-time multiple frequency fault detection, correction and identification system for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Condition monitoring was performed on the displacement signals of a fully suspended 250 kW water cooling AMB pump, to obtain historical fault data. A pattern recognition system compared the realtime displacement error patterns with the displacement error patterns from the historical fault database. A fuzzy logic system used the patterns from the pattern recognition system to perform error correction. The Wigner-Ville distribution extracted the vibratory amplitudes and frequencies, which was used as input features to the pattern construction and pattern recognition systems. Experiments were performed on a double radial AMB test rack to demonstrate the effectiveness of the proposed system in the detection, correction and identification of vibration forces on the rotor of an AMB system. The detection and correction system was able to correct and minimize multiple frequency vibration forces to a stable working condition. The identification system calculated the type, parameters, vibratory level and zone of the vibration forces. The main advantage of this system is its capability to detect, correct and identify multiple frequency vibration forces.

Lagrangian relaxation based algorithms for convex programming problems

This thesis deals with a class of Lagrangian relaxation based algorithms developed in the computer science community in last couple of decades. We present a unified framework for designing such algorithms for a large family of convex programming problems. Our algorithms are based on exponential potential functions and given any 2 (0; 1), compute (1 + )-approximate solutions in number of iterations proportional to 2. We present an algorithm for the general resource sharing problem which may have both positive and negative entries in the constraints. We improve and generalize the results of Plotkin-ShmoysTardos and Young to convex and concave functions. Using this, we obtain faster algorithms for computing fractional solution to the Steiner forest problem and Held-Karp bounds for TSP. We formulate a new problem called the provisioning problem and obtain an approximation scheme for it. Using this framework, we obtain width-independent running times for solving the generalized hitting set problems fractionally. We extend this framework to the mixed packing and covering problems with convex and concave functions over arbitrary convex sets, thereby solving an open problem of Young. We also obtain approximation schemes for computing primal and dual solutions for min-max and max-min resource sharing problems. Our algorithms use “variable-size increments” and have width-independent running times. We formulate a new problem called the substitute mixed problem. We show that the “roundrobin increments” can be used to design efficient algorithms for this problem. We also present algorithms for the special cases of the substitute packing and covering problems. Using this, we design faster approximation algorithms for computing the size of the maximum cuts in weakly bipartite graphs and the maximum independent sets in t-perfect graphs. We also show that the substitute mixed problem generalizes the block-angular min-max and max-min resource sharing problems and obtain better running times than those given by Grigoriadis-Khachiyan. Our framework can also be used to solve the linear versions of the above abstract problems including packing, covering, mixed packing and covering. Under some conditions, we extend our techniques to linear programs which may have negative entries. Using these ideas, we improve the recent results of Fleischer for covering with upper bounds on the variables.
Reflective Student Engagement: A Necessity for Effective ODL Delivery

Education providers need to be effectively engaged with their students in order to better understand their expectations and therefore tailor their deliveries to meet their needs accordingly. In a normal conventional, face-to-face small class arrangement, this is feasible and even sufficient but not so in an era of mass education delivered through open and distance learning method coupled with student diversity and less homogeneity in their class composition. This arrangement presents a challenge for teachers to understand the peculiarities and expectations of their students. To achieve better inclusive engagement with students and to deliver learning content based on their expectations, a more formal means to understand students as learners becomes necessary. This calls for a method that can enable teachers to learn and understand students’ expectations of teaching, learning and assessment as well as their conceptions and views of learning, their belief system and their reflective thinking capabilities. Survey was used in this study and 100 students of National Open University of Nigeria, were randomly selected. Sixteen item questionnaire administered with 56 returns. Results showed effective engagement of students occurs through class participation, interaction and collaboration with peers, attentiveness in class activity, emotional connection – and were found necessary for effective open and distance learning delivery. Management needs to also make deliberate effort to enhance students’ engagement by being responsive to their (students’) needs as expressed from time to time, such as extra-curricular activities and creation of physical interaction between and among staff and faculty.
Novel Vaccine Strategies and Factors to Consider in Addressing Health Disparities of HPV Infection and Cervical Cancer Development among Native American Women

Cervical cancer is the 4th most common type of cancer in women world-wide. Many factors play a role in cervical cancer development/progression that include genetics, social behaviors, social determinants of health, and even the microbiome. The prevalence of HPV infections and cervical cancer is high and often understudied among Native American communities. While effective HPV vaccines exist, less than 60% of 13- to 17-year-olds in the general population are up to date on their HPV vaccination as of 2020. Vaccination rates are higher among Native American adolescents, approximately 85% for females and 60% for males in the same age group. Unfortunately, the burden of cervical cancer remains high in many Native American populations. In this paper, we will discuss HPV infection, vaccination and the cervicovaginal microbiome with a Native American perspective. We will also provide insight into new strategies for developing novel methods and therapeutics to prevent HPV infections and limit HPV persistence and progression to cervical cancer in all populations.
Analysis of the impact of China's deposit reserve policy on the liquidity of local legal person financial institutions

: The deposit reserve policy is a monetary policy tool established under the central banking system.Since the People's Bank of China performed its duties as the Central Bank in the 1980s, China's deposit reserve system has been established and gradually improved.At present, China has basically formed a "three files and two excellent" deposit reserve framework.As one of the three major monetary policy tools of the central bank, the deposit reserve policy affects the liquidity of financial institutions and the banking system through the excess reserve ratio and the monetary multiplier effect, and the liquidity of the banking system is related to the financial stability of a country and the prevention of systemic financial risks.Therefore, it is important to study the impact of deposit reserve policy on liquidity. In this paper, the monthly data of 16 legal person financial institutions in a certain region from January 2017 to May 2021 were selected as the study sample, To carry out empirical research on the impact of China's deposit reserve ratio changes on the liquidity of financial institutions in a certain region, And the capital adequacy ratio, interbank lending rate and other indicators are introduced as internal and external influencing factors, The results show that the legal deposit reserve ratio has a certain impact on the liquidity of financial institutions, However, different types of financial institutions and different influencing factors make the impact of the legal deposit reserve ratio on liquidity different, And the impact of the legal deposit reserve ratio on liquidity has a certain time lag.Through carrying out empirical research, this paper hopes to further enrich the theoretical achievements in the field of deposit reserve and liquidity, and provide a reasonable basis for the central bank to better play the market regulation role of deposit reserve policy.
Risk, Obligation, and Public Noncompliance with Mobility Directives in China during the COVID-19 Pandemic

Human mobility greatly increases the risk of epidemic transmission. This study examines the psychological mechanism of individuals’ noncompliance with public health directives and their choice to travel amidst threats through two rounds of surveys (N = 1473 in total) in China at different stages of the COVID-19 pandemic. This research revealed the relative strength of the motivating and impeding factors that determined behavioral intention. In subtle internal conflicts, maladaptive responses (e.g., wishful thinking, denial, fatalism) were identified as a significant factor in negotiating risk-related constraints and encouraging risky travel behavior. Interestingly, both those who traveled amidst threats and those who did not travel agreed that they had social obligations for epidemic prevention. The results demonstrated that obligation could have an indirect negative impact on behavioral intention only via attitude. By unveiling the psychological mechanism of individuals’ noncompliance with health directives and travel during the pandemic, this study can aid in the development of appropriate operational strategies to manage population mobility during crises.
Skeletal stem cells: a game changer of skeletal biology and regenerative medicine?

Abstract Skeletal stem cells (SSCs) were originally discovered in the bone marrow stroma. They are capable of self-renewal and multilineage differentiation into osteoblasts, chondrocytes, adipocytes, and stromal cells. Importantly, these bone marrow SSCs localize in the perivascular region and highly express hematopoietic growth factors to create the hematopoietic stem cell (HSC) niche. Thus, bone marrow SSCs play pivotal roles in orchestrating osteogenesis and hematopoiesis. Besides the bone marrow, recent studies have uncovered diverse SSC populations in the growth plate, perichondrium, periosteum, and calvarial suture at different developmental stages, which exhibit distinct differentiation potential under homeostatic and stress conditions. Therefore, the current consensus is that a panel of region-specific SSCs collaborate to regulate skeletal development, maintenance, and regeneration. Here, we will summarize recent advances of SSCs in long bones and calvaria, with a special emphasis on the evolving concept and methodology in the field. We will also look into the future of this fascinating research area that may ultimately lead to effective treatment of skeletal disorders.
Gondwana Sequence of the northern Pranhita-Godavari Valley: its stratigraphy and vertebrate faunas

The Gondwana Sequence in the northern part of the Pranhita-Godavari Valley consists of four formations of the Lower Gondwana and seven formations of the Upper Gondwana. The gross lithological characters and mappability are considered as the major criteria for delineating the formations. The name Kamthi Formation which has been used by different authors in different senses, is here used in the sense of Sengupta (1970). The rocks between the Barakar and this Kamthi are divided into four lithozones for limitations of mappability. Although some of these lithozones have earlier been designated as formations, at present not sufficient information is available to justify this. Only two breaks, both within the Upper Gondwana, are found to be present: there is no recognisable break between the Lower and the Upper Gondwana. A summary of this succession is presented in tabular form taking into account the words of earlier authors. The alternative views that are radically different from the one presented here are also discussed briefly. The usefulness of plant megafossils and fossil vertebrates in understanding the stratigraphy is discussed briefly and their role in determining the possible geological ages of some of the formations is mentioned. The vertebrate fauna from a number of formations is listed. At least seven formations are fossiliferous as far as vertebrates are concerned. Of these, two belonging to the Triassic and one belonging to the Jurassic are quite well-documented. The other four are less well known, but serve as very useful time markers. All these vertebrate-bearing formations can be correlated with co-eval rocks elsewhere in the world. The difficulty of correlating continental deposits is realized and keeping this in view a tentative correlation is presented.
Literature Study of Zakat Distribution in Indonesia

Zakat has great potential to overcome problems in Indonesia such as poverty alleviation, access to education and health for zakat mustahik, but the implementation of zakat in Indonesia is faced with a number of problems. Zakat is divided into two categories, namely internal problems and external problems. Zakat is carried out in three ways, namely, first, baznas actively participate in the community without waiting for muzakki to pay zakat. Second, the Zakat distributed to the public apart from being in the form of zakat in general, is also adjusted to the community's needs for COVID-19 and is periodically balanced with monitoring and evaluation. Third, Zakat which is developed in both consumptive and productive forms has become a mental solution and welfare for the community. The distribution of zakat carried out by BAZNAS has a different percentage of distribution due to differences in the vision and mission of each zakat institution. Problems that occur in the distribution of zakat in Indonesia can be done by knowing the main problems that occur on the external and internal sides.

Pada penelitian ini dilakukan upaya untuk meningkatkan ketangguhan mekanis Unsaturated Polyester (UP) dengan menambahkan Thermoset Vinyl Ester (VE) dan Methyl Methacrylate (MMA). Untuk menunjukkan tingkat ketangguhan material dilakukan pengujian dengan memberikan beban lentur sampai material tersebut putus. Hasil pengujian menunjukkan bahwa campuran 40 % wt VE dan 10% wt MMA pada material UP menghasilkan peningkatan sifat ketangguhan material dari pengujian bending stress pada spesimen dengan variasi komposisi polyester dan vinyl ester dengan hand lay-up. Nilai tegangan lentur tertinggi terdapat pada komposisi 60% polyester dan 40% vinyl ester yaitu sebesar 126,88 MPa (meningkat 16 % dari polyester murni). In this study, an attempt was made to increase the mechanical toughness of unsaturated polyester (UP) by adding Thermoset Vinyl Ester (VE) and Methyl Methacrylate (MMA). A test is carried out to show the level of toughness of the mechanical properties of the above material by applying a flexural load until the material breaks. The test results showed that a mixture of 40% wt VE and 10% wt MMA in UP material resulted in an increase in the toughness properties of the material from the bending stress test on specimens with variations in the composition of polyester and vinyl ester with hand lay-up. The highest flexural stress value is found in the composition of 60% polyester and 40% vinyl ester, which is 126.88 MPa (an increase of 16% from pure polyester).
Adjoint operator approach to shape design for internal incompressible flows

The problem of determining the profile of a channel or duct that provides the maximum static pressure rise is solved. Incompressible, laminar flow governed by the steady state Navier-Stokes equations is assumed. Recent advances in computational resources and algorithms have made it possible to solve the direct problem of determining such a flow through a body of known geometry. It is possible to obtain a set of adjoint equations, the solution to which permits the calculation of the direction and relative magnitude of change in the diffuser profile that leads to a higher pressure rise. The solution to the adjoint problem can be shown to represent an artificially constructed flow. This interpretation provides a means to construct numerical solutions to the adjoint equations that do not compromise the fully viscous nature of the problem. The algorithmic and computational aspects of solving the adjoint equations are addressed. The form of these set of equations is similar but not identical to the Navier-Stokes equations. In particular some issues related to boundary conditions and stability are discussed.
