description: The Cannon is a flexible, data-driven spectral-modeling and parameter-inference framework, demonstrated on high-resolution, near-infrared SDSS-IV APOGEE spectra of giant stars to estimate stellar labels (Teff , logg, [Fe/H], and detailed abundances) to precisions higher than the APOGEE model-grid pipelines. The lack of reliable atmospheric models in the near infrared for temperatures cooler than ∼3550 K motivates the extension of this approach to M-dwarf stars, but with calibrated training labels from optical surveys that overlap with APOGEE. Training two models (one for temperature/metallicity and one for spectral type) spanning temperatures 2860 < Teff < 4130 K, metallicities −0.5 < [Fe/H] < 0.5 dex, and classifications M0 to M9, we demonstrate predictive accuracies (in cross-validation) of 77 K, 0.09 dex and 0.9 subtypes, respectively. We apply our models to 10,311 sources selected from the overlap of APOGEE and Gaia DR2, and compare our Cannon-derived Teff against color–temperature relations, finding better agreement than pipeline measurements, and compare [Fe/H] against isochrone models in Gaia color-magnitude space. Finally we use empirically-calibrated relations to estimate radii from K-band absolute magnitudes and Cannon temperatures.

description: Introduction: Bariatric surgery is being increasingly investigated as treatment for Type II Diabetes Mellitus (T2DM). As Sleeve Gastrectomy (SG) surpasses Roux-en-Y Gastric Bypass (RYGB) as the new standard in bariatric surgery, it is still unknown if its efficacy in achieving remission is comparable to RYGB. This study compared diabetic remission rates between SG and RYGB in order to identify the predictive factors for remission and the mechanisms of achieving remission.

Methods: This was a retrospective cohort study comparing all diabetic patients undergoing RYGB and SG at an academic medical center from 1/1/11-7/1/15. Patients were followed preoperatively and at 6 week, 6 month, and 1, 2, and 3 year intervals. We defined diabetic remission as HbA1c under 7 without insulin or hypoglycemic use and excess body weight (EBW) as percent over ideal body weight. Data were analyzed using Cox analysis, Fisher’s Exact Tests, and Student T Tests.

Results: During the study, 96 patients underwent RYGB and 89 underwent SG. Preoperatively, patients from both groups had similar age, weight, gender, preoperative weight loss, HbA1c at onset and at surgery, oral hypoglycemic use, insulin use, and HOMA2 parameters. At one year postoperatively, patients who underwent RYGB showed a statistically greater postoperative EBW loss (62% vs. 36% p < 0.0001). Kaplan Meier analysis showed a significantly higher rate of remission, (83% vs. 66%) in patients who underwent SG (p=0.02). After using Cox analysis to account for differences in delta BMI (p=0.04), EBW loss (p=0.04), preoperative HOMA2 parameters (p=0.008-0.011), and preoperative factors such as HbA1c and insulin use (p=0.001 for both), there was no change in RYGB’s impact on diabetic remission compared to SG.

Conclusion: Our results confirm that RYGB achieves a significantly greater rate of diabetic remission and a significantly higher weight loss than SG. Additionally, the difference in rate of diabetic remission is not explained by weight loss or preoperative predictors of less reversible diabetes (HOMA2 parameters, use of insulin). Identification of the factor(s) responsible for this differential effect on diabetes may afford opportunity for therapeutic intervention.

description: Multiparticle systems on complicated metric graphs might have many applications in physics, biology and social life. But the corresponding science still does not exist. Here we start it with simplest examples where there is quadratic interaction between neighboring particles and deterministic external forces. In this introduction we consider stable configurations and stable flows on one and two edge graphs. Moreover, distribution of mean (as in virial theorem) kinetic and potential energies along the graph is considered.

description: We report a sudden reversal in the pressure dependence of Tc in the iron-based superconductor CsFe2As2, similar to that discovered recently in KFe2As2 [Tafti et al., Nat. Phys. 9, 349 (2013)]. As in KFe2As2, we observe no change in the Hall coefficient at the zero temperature limit, again ruling out a Lifshitz transition across the critical pressure Pc. We interpret the Tc reversal in the two materials as a phase transition from one pairing state to another, tuned by pressure, and investigate what parameters control this transition. Comparing samples of different residual resistivity, we find that a 6-fold increase in impurity scattering does not shift Pc. From a study of X-ray diffraction on KFe2As2 under pressure, we report the pressure dependence of lattice constants and As-Fe-As bond angle. The pressure dependence of these lattice parameters suggests that Pc should be significantly higher in CsFe2As2 than in KFe2As2, but we find on the contrary that Pc is lower in CsFe2As2. Resistivity measurements under pressure reveal a change of regime across Pc, suggesting a possible link between inelastic scattering and pairing symmetry.

description: Pompe disease is a rare autosomal recessive disease which results from a deficiency of acid α-glucosidase (GAA) - an enzyme that degrades lysosomal glycogen. Patients with Pompe disease develop intra-lysosomal accumulation of glycogen in multiple tissues including skeletal muscle, CNS and smooth muscle.

Pulmonary dysfunction is a hallmark of Pompe disease and has classically been attributed to muscle weakness and CNS neuropathology. However, the potential role of respiratory smooth muscles in the respiratory pathology is unknown. Therefore we postulated that GAA deficiency results in airway smooth muscle glycogen accumulation that leads to airway smooth muscle dysfunction.

Using the Pompe mouse model, the Gaa-/- mouse, we examined the airway smooth muscle structure and function. We used in vivo forced oscillometry measurements (N=7WT, N=7 Gaa-/-) to examine pulmonary physiology and administered methacholine challenges to assess in vivo airway resistance. Also, we used ex-vivo contraction testing (N=6WT, N=5 Gaa-/-) to determine bronchi contractility. In response to the highest dose methacholine challenge (100mg/ml), there was a significant decrease in conducting airway resistance in Gaa-/- versus WT mice (p=0.007). Also, ex vivo bronchi contraction testing demonstrated a significantly weaker response to potassium chloride (p=0.008) and methacholine (2-way ANOVA p=0.005) in Pompe mice compared to WT mice, suggesting impaired smooth muscle contraction. Furtherly, we performed PAS staining on fresh-frozen tissue to examine the degree of glycogen accumulation as a result of GAA deficiency. PAS staining revealed robust glycogen accumulation in the trachea and bronchi of Pompe mice and a disruption of the airway smooth muscle architecture.

In conclusion, GAA deficiency results in glycogen accumulation and a disruption of the architecture in the airway smooth muscles of Gaa-/- mice. Furthermore, both in vivo and ex vivo tests reveal that Gaa-/- murine airways have impaired function as evidenced by decreased contractility and a decreased response to methacholine.

description: We construct a family of simple fermionic projected entangled pair states (fPEPS) on the square lattice with bond dimension $D=3$ which are exactly hole-doped resonating valence bond (RVB) wavefunctions with short-range singlet bonds. Under doping the insulating RVB spin liquid evolves immediately into a superconductor with mixed $d+is$ pairing symmetry whose pair amplitude grows as the square-root of the doping. The relative weight between $s$-wave and $d$-wave components can be controlled by a single variational parameter $c$. We optimize our ansatz w.r.t. $c$ for the frustrated $t-J_1-J_2$ model (including both nearest and next-nearest neighbor antiferromagnetic interactions $J_1$ and $J_2$, respectively) for $J_2\simeq J_1/2$ and obtain an energy very close to the infinite-PEPS state (using full update optimization and same bond dimension). The orbital symmetry of the optimized RVB superconductor has predominant d-wave character, although we argue a residual (complex s-wave) time reversal symmetry breaking component should always be present. Connections of the results to the physics of superconducting cuprates and pnictides are outlined.

description: Hospital readmission rate has become a major indicator of quality of care, with penalties given to hospitals that have high rates of readmission. At the same time, insurers are applying increasing pressure to improve efficiency and reduce costs, including decreasing hospital lengths of stay. We analyze these trends to determine if reducing lengths of stay (LOS) may actually worsen readmission rates. All records of patients admitted to the neurosurgical service at one hospital from October 2007 through June 2014 were aggregated and analyzed for several variables, including initial length of stay, readmission occurrence, and length of stay, admitting diagnosis, admission priority and discharge disposition. Any trends over time were also noted. 925 out of 9,409 patient encounters are readmissions. Readmission rate and average length of stay were found significantly negative correlated. Besides linear regression which directly connecting average length of stay and readmission rate, survival analysis methods with Cox proportional hazard ratio model were employed to determine which factors were associated with a higher risk of readmission. There was a clear increase in readmissions over the study period, but LOS remained relatively constant, suggesting that increasing medical complexity confounded efforts to decrease LOS and was responsible for increased readmission rates. This study can help providers avoid readmissions by focusing on effective management of comorbidities.

description: Polo-like kinase 1 (PLK1) and BRD4 are two different therapeutic targets in cancer drug discovery. Recently it has been reported that PLK1 inhibitor, BI-2536, is also a potent inhibitor of BRD4. The simultaneous inhibition of PLK1 and BRD4 by a single drug molecule is interesting because this could lead to the development of effective therapeutic strategy for different types of disease conditions in which PLK1 and BRD4 are implicated. Structural activity relationship studies has been carried out on BI-2536 to generate analogs with enhanced dual inhibitory activity against BRD4 and PLK1 as well as to render the molecule selective to one target over the other. UMB101 and 160 have been found to exhibit enhanced dual inhibitory activity with selectivity fold of less than 30, UMB160 being the most potent dual-kinase bromodomain inhibitor (BRD4 IC50 = 28 nM, PLK1 IC50 = 40 nM). UMB131 was found to be the most selective PLK1 inhibitor over BRD4.

description: In light of the recent observational data coming from the sky we have two significant directions in the field of theoretical cosmology recently. First, we are now able to make use of present observations, such as the Planck and BICEP2 data, to examine theoretical predictions from the standard inflationary $Λ$CDM which were made decades of years ago. Second, we can search for new cosmological signatures as a way to explore physics beyond the standard cosmic paradigm. In particular, a subset of early universe models admit a nonsingular bouncing solution that attempts to address the issue of the big bang singularity. These models have achieved a series of considerable developments in recent years, in particular in their perturbative frameworks, which made brand-new predictions of cosmological signatures that could be visible in current and forthcoming observations. In this article we present two representative paradigms of very early universe physics. The first is the so-called new matter (or matter-ekpyrotic) bounce scenario in which the universe starts with a matter-dominated contraction phase and transitions into an ekpyrotic phase. In the setting of this paradigm, we propose some possible mechanisms of generating a red tilt for primordial curvature perturbations and confront its general predictions with recent cosmological observations. The second is the matter-bounce inflation scenario which can be viewed as an extension of inflationary cosmology with a matter contraction before inflation. We present a class of possible model constructions and review its implications on the current CMB experiments. Last, we review the significant achievements of these paradigms beyond the inflationary $Λ$CDM model, which we expect to shed new light on the direction of observational cosmology in the next decade years.

description: Biodegradable polymers have been widely utilized as drug delivery vehicles and tissue engineering scaffolds. We previously designed amphiphilic triblock copolymer poly(lactic acid)-b-poly(ethylene glycol)-b-poly(lactic acid) (PELA) and its hydroxyapatite (HA) composites for bone tissue engineering applications. The hydrophilic electrospun PELA-HA composite exhibited aqueous stability and elastic handling characteristics, and was able to template the proliferation and osteogenesis of bone marrow stromal cells (BMSCs) in vitro and in vivo when spiral-wrapped into cylinders and press-fit into critical size femoral segmental defects in rats. However, the slow degradation of PELA has prevented timely disappearance of the scaffold and impeded more effective restoration of biomechanical integrity of the defect. To accelerate degradation, in this work we designed poly(lactic/glycolic acid)-b-poly(ethylene glycol)-b-poly(lactic/glycolic acid) (PELGA) with varying ratios of glycolide and lactide and confirmed their more accelerated degradations as compared to PELA. Processing conditions (e.g. solvent-casting vs. electrospinning, with or without hydration) significantly impacted the structural characteristics of PELGA and their HA composites. The PEG crystallization in PELGA was not as strong as in PEG homopolymers, giving rise to a lower Tm. HA could be well dispersed in PELGA and electrospun to give a uniform composite where the crystallization of PEG was promoted by water resulting in enhanced mechanical strength upon hydration. These HA-contained electrospun meshes exhibited excellent cytocompatibility and efficacy in templating osteogenesis of rat BMSCs in vitro.
Becoming Nessa’ Mumaknat to reform professional femininity: Saudi professional women, identity work and online personal branding

description: This thesis aims to explore the identity construction of Saudi professional women through online personal branding in LinkedIn within the collectivist, conservative, and masculine culture of Saudi Arabia. In particular, this thesis analyses the extent to which women are affected by gendered sociocultural contexts. Using a qualitative methodology that draws on in-depth interviews with 39 Saudi female professionals who use LinkedIn, the findings suggest that the ways Saudi women construct their professional identity through online personal branding are driven by the tensions inherent in online identity work and by three other issues. These issues are the impact of sociocultural rules, the domination of guardianship, and the notion of ideal femininity. Also, the present study shows that Saudi professional women use professional identity to move from being Nessa’ Muhamashat (marginalised women) to becoming Nessa’ Mumaknat (empowered women). Finally, the unique ways of professional identity construction of Saudi women reflect how they reform professional femininity in that they play the role from ‘we’ as a collective identity to ‘we’ as change-makers. This thesis makes key contributions on Middle Eastern women and identity construction. It involves identifying a professional form of identity work through online personal branding in the Middle Eastern context and differentiating social media usage in a professional context for Saudi women. Also, it contributes to the concept of women’s empowerment (Tamkeen Almara’ah) for Saudi women. The present study reforms professional femininity in its modern and professional form by criticising the traditional concept of the ‘ideal Islamic woman’. Thus, professional identity construction for Saudi women through identity work and online personal branding differs from a western context in terms of its meaning and circumstances and reveals Saudi women’s needs to overcome online tensions to xi move from being Nessa’ Muhamashat to becoming Nessa’ Mumaknat in society and reforming the professional femininity to fit professional contexts.

description: We present a computational study on the topology, energetics and structural deformations for a large number of experimentally observed defect configurations in graphene. We find that both the number of lost hexagonal carbon rings and introduced non-hexagonal rings increase linearly as a function of the vacancy order (number of missing atoms). The formation energies of the defects increase by about 2.2 eV per missing atom after an initial offset, establishing these defects as the lowest energy vacancy configurations studied in graphene to date. In addition, we find that even small point defects, which have been until now assumed flat, cause graphene to bend out of plane when not restricted into prohibitively confined geometries. This effect reaches to relative long distances even for some of the smallest defects, significantly reducing the stress otherwise imposed on the surrounding lattice.

description: We use CheMPS2, our free open-source spin-adapted implementation of the density matrix renormalization group (DMRG) [Wouters et al., Comput. Phys. Commun. 185, 1501 (2014)], to study the lowest singlet, triplet, and quintet states of the oxo-Mn(Salen) complex. We describe how an initial approximate DMRG calculation in a large active space around the Fermi level can be used to obtain a good set of starting orbitals for subsequent complete-active-space or DMRG self-consistent field (CASSCF or DMRG-SCF) calculations. This procedure mitigates the need for a localization procedure, followed by a manual selection of the active space. Per multiplicity, the same active space of 28 electrons in 22 orbitals (28e, 22o) is obtained with the 6-31G*, cc-pVDZ, and ANO-RCC-VDZP basis sets (the latter with DKH2 scalar relativistic corrections). Our calculations provide new insight into the electronic structure of the quintet.

description: Objective. The vast majority of diets are not only multicomponent but also restrictive. Dietary fiber or protein can reduce hunger and enhance satiety; they also exert clinical benefits. We examined feasibility and acceptability of a non-restrictive diet combining the two for weight loss.

Population and Methods. Fifteen patients were enrolled in the trial (2 men, 13 women, mean age=48 y and mean BMI = 36 kg/m2) to attend 6 bi-weekly individual counselling sessions for the diet during the 12-week study period. The goals of the intervention were to attain a daily goal of higher fiber (>35g)/ and lean protein (120g). 24-hour diet recalls and body weight were collected at baseline, 6- and 12-week assessments.

Results. All participants completed 6-week assessment, one participant dropped from the study before 12-week assessment. At 12 weeks, 93% of participants liked the diet much/very much, 92% were very/extremely confident in adhering to the diet and 85% did not feel hungry on the diet. Mean fiber intake increased by 9.4 g/day (95% CI: 5.9, 12.8) at 6 weeks, and by 6.9 g/day (CI: 3.3, 10.5) at 12 weeks. Protein intake increased by a mean of 13.7 g/day (CI: 4.8, 22.6) at 6 weeks, and by 6.0 g/day (CI: -3.3, 15.3) at 12 weeks. % of calories from saturated fat decreased by 2.0% (CI: 0.5, 3.4) at 6 weeks and by 2.7% (CI: 0.5, 3.4) at 12 weeks. Alternative Healthy Eating Index score increased by 9.7 (CI: 5.3, 14.0) at 6 weeks and by 6.1 (CI: 1.5, 10.7) at 12 weeks. Mean weight loss was -2.7 lbs (CI: -4.9, 0.6) at 6 weeks and -4.7 lbs (CI: -8.0, -1.4) at 12 weeks.

Conclusion. Participants liked the diet prescribed, and significantly increased their fiber and lean protein intake, resulting in significant weight loss with improvement to dietary quality.

description: The 2016 November 14 Kaikōura MW 7.8 earthquake occurred in the northern South Island of New Zealand, rupturing several faults of the Marlborough Fault System … The Marlborough Fault System accommodates 35–40 mm/year of relative motion between the Pacific and Australian plates (Beavan et al. 2002). This motion is accommodated primarily through slip on the right-lateral Wairau (4.4–5.4 mm/yr; Seebeck et al. 2022), Awatere (4–8 mm/yr), Clarence (3.5–5 mm/yr), Kekerengu (20–26 mm/yr) and Hope faults. The 2016 earthquake occurred close to the Hope Fault, which has one of the fastest Late Holocene slip rates of these faults (up to ~25 mm/year; Langridge et al. 2003; Little et al. 2018). The Kaikōura earthquake nucleated on or near the Humps Fault in North Canterbury … and propagated northeast (Duputel and Rivera 2017; Kaiser et al. 2017); it ruptured over 20 onshore and offshore faults with a wide variety of fault orientations and slip styles (Litchfield et al. 2018). Almost half of the faults that ruptured during the earthquake had not been mapped previously, although most seismic moment was released on faults that had been mapped. Surprisingly, slip on the Hope Fault was minimal (<1 m; Litchfield et al. 2018), despite (1) its favourable orientation for the accommodation of relative Australia–Pacific plate motion in the region (Nicol et al. 2018) and (2) the rupture of similarly oriented faults north and south of the Hope Fault. The faults that ruptured in the Kaikōura earthquake can be divided spatially into two groups, separated by the Hope Fault ... The southern group includes the Humps, Leader, Conway-Charwell and Hundalee faults, among others (Litchfield et al. 2018; Nicol et al. 2018). The northern group of faults includes the Papatea, Kekerengu and Needles faults and several faults in the Seaward Kaikōura Range (Kearse et al. 2018; Langridge et al. 2018; Litchfield et al. 2018; Zinke et al. 2019; Howell et al. 2020).

description: The Domus Aurea, Nero's last "palace" constructed in the very heart of ancient Rome, is a true masterpiece of Roman architecture. We explore here symbolic aspects of the emperor's project, analysing the archaeoastronomy of the best preserved part of the Domus, the Esquiline Wing. In particular, we study the so-called Octagonal Room, the huge vaulted room which is in many respects a predecessor of the Pantheon. The project of the room turns out to be connected with astronomy, as will be that of the Hadrian's Pantheon 60 years later. Indeed, the divinization and "solarisation" of the emperor placed at the equinoxes as a point of balance in the heavens are shown to be explicitly referred to in the rigorous orientation of the plan and in the peculiar geometry of the design of the dome.

description: We study the mechanisms of the gravitational collapse of the Bose-Einstein condensate dark matter halos, described by the zero temperature time-dependent nonlinear Schrödinger equation (the Gross-Pitaevskii equation), with repulsive inter-particle interactions. By using a variational approach, and by choosing an appropriate trial wave function, we reformulate the Gross-Pitaevskii equation with spherical symmetry as Newton's equation of motion for a particle in an effective potential, which is determined by the zero point kinetic energy, the gravitational energy, and the particles interaction energy, respectively. The velocity of the condensate is proportional to the radial distance, with a time dependent proportionality function. The equation of motion of the collapsing dark matter condensate is studied by using both analytical and numerical methods. The collapse of the condensate ends with the formation of a stable configuration, corresponding to the minimum of the effective potential. The radius and the mass of the resulting dark matter object are obtained, as well as the collapse time of the condensate. The numerical values of these global astrophysical quantities, characterizing condensed dark matter systems, strongly depend on the two parameters describing the condensate, the mass of the dark matter particle, and of the scattering length, respectively. The stability of the condensate under small perturbations is also studied, and the oscillations frequency of the halo is obtained. Hence these results show that the gravitational collapse of the condensed dark matter halos can lead to the formation of stable astrophysical systems with both galactic and stellar sizes.

description: In this paper we study K-cosymplectic manifolds, i.e., smooth cosymplectic manifolds for which the Reeb field is Killing with respect to some Riemannian metric. These structures generalize coKähler structures, in the same way as K-contact structures generalize Sasakian structures. In analogy to the contact case, we distinguish between (quasi-)regular and irregular structures; in the regular case, the K-cosymplectic manifold turns out to be a flat circle bundle over an almost Kähler manifold. We investigate de Rham and basic cohomology of K-cosymplectic manifolds, as well as cosymplectic and Hamiltonian vector fields and group actions on such manifolds. The deformations of type I and II in the contact setting have natural analogues for cosymplectic manifolds; those of type I can be used to show that compact K-cosymplectic manifolds always carry quasi-regular structures. We consider Hamiltonian group actions and use the momentum map to study the equivariant cohomology of the canonical torus action on a compact K-cosymplectic manifold, resulting in relations between the basic cohomology of the characteristic foliation and the number of closed Reeb orbits on an irregular K-cosymplectic manifold.

Unsolvability Cores in Classification Problems

description: Classification problems have been introduced by M. Ziegler as a generalization of promise problems. In this paper we are concerned with solvability and unsolvability questions with respect to a given set or language family, especially with cores of unsolvability. We generalize the results about unsolvability cores in promise problems to classification problems. Our main results are a characterization of unsolvability cores via cohesiveness and existence theorems for such cores in unsolvable classification problems. In contrast to promise problems we have to strengthen the conditions to assert the existence of such cores. In general unsolvable classification problems with more than two components exist, which possess no cores, even if the set family under consideration satisfies the assumptions which are necessary to prove the existence of cores in unsolvable promise problems. But, if one of the components is fixed we can use the results on unsolvability cores in promise problems, to assert the existence of such cores in general. In this case we speak of conditional classification problems and conditional cores. The existence of conditional cores can be related to complexity cores. Using this connection we can prove for language families, that conditional cores with recursive components exist, provided that this family admits an uniform solution for the word problem.

description: L1642 is one of the two high galactic latitude (|b| > 30deg) clouds confirmed to have active star formation. We examine the properties of this cloud, especially the large-scale structure, dust properties, and compact sources in different stages of star formation. We present high-resolution far-infrared and submm observations with the Herschel and AKARI satellites and mm observations with the AzTEC/ASTE telescope, which we combined with archive data from near- and mid-infrared (2MASS, WISE) to mm observations (Planck). The Herschel observations, combined with other data, show a sequence of objects from a cold clump to young stellar objects at different evolutionary stages. Source B-3 (2MASS J04351455-1414468) appears to be a YSO forming inside the L1642 cloud, instead of a foreground brown dwarf, as previously classified. Herschel data reveal striation in the diffuse dust emission around L1642. The western region shows striation towards NE and has a steeper column density gradient on its southern side. The densest central region has a bow-shock like structure showing compression from the west and a filamentary tail extending towards east. The differences suggest that these may be spatially distinct structures, aligned only in projection. We derive values of the dust emission cross-section per H nucleon for different regions of the cloud. Modified black-body fits to the spectral energy distribution of Herschel and Planck data give emissivity spectral index beta values 1.8-2.0 for the different regions. The compact sources have lower beta values and show an anticorrelation between T and beta. Markov chain Monte Carlo calculations demonstrate the strong anticorrelation between beta and T errors and the importance of mm Planck data in constraining the estimates. L1642 reveals a more complex structure and sequence of star formation than previously known.

Busiz ta'lim tizimini xalqaro talab darajalarga olib chiqish mumkin emas, agar jamiyatda o'qituvchi o'zining hayotidan mamnun bo'lsa uning o'broyi  yuqori bo'lsa qilinayotgan islohotlar tez meva beradi.  Men buni amalga oshirish uchun quyidagi takliflarni ilgari suraman. Birinchidan o'qituvchiga tom ma'noda erkinlik berish kerak o'qituvchi dars jarayonini qanday tashkil qilishini o'zi hal qilishi kerak. O'qituvchi muayyan bir qolibdan chiqib shaxsiy qiziqishlarni ifoda qilishi kerak. Ikkinchidan ta'lim tizimining yomon jihati hisoblangan forma, davomat va tashkiliy ishlardan tola ozod qilinishi kerak. Uchinchidan o'qituvchilarning maoshlarini o'rta qatlam vakillari bilan teng bo'lishini taminlash maqsadga muvofiq bo'ladi. To'g'ri turli sertifikat olgan o'qituvchilarning maoshlari yuqori lekin oddiy o'qituvchining ham maoshi jamiyatdagi o'rta hollardagilar bilan bir xil bo'lishi kerak. Bu ishlar amalga oshirmasdan turib yangi O'zbekistonda uchinchi renessans  poydevorini qurib bo'lmaydi.

The fifth dimension in the worldline formalism, holography, and the Wilson flow

description: We develop a model for hadrons in the framework of the worldline formalism. While being based wholly in four-dimensional quantum field theory, it shares many features with holographic approaches: Already by the use of the worldline formalism the approach appears intrinsically quantum mechanical. As auxiliary fifth dimension Schwinger's proper time is grouped with the physical four spacetime dimensions into an AdS5 geometry, which is warped due to conformal-symmetry breaking effects. Hidden local symmetry is emergent. The four-dimensional sources are extended to five-dimensional fields by a Wilson flow (gradient flow). A variational principle for the flow reproduces exactly the corresponding holographic computation. The worldline approach also yields the higher-dimensional description in the non-relativistic case.
