description: In this interview, McCall discusses her and her husband's upbringing, how the black press has changed over the years, her marriage, and the early years of her life in Detroit. She chronicles the various owners and phases of the Detroit Tribune and her husband's employment through the Great Depression. McCall reflects on how the platform of the Tribune was used, including: campaigns for black judges; African American voter mobilization; charity activities on Christmas; and publicity for the personal threats her family had received from white supremacists. She interprets the advances made by the black press and black communities throughout her life. Also discussed is: the uncertain future of black newspapers; the distinctions between the black and white press; and the impact of television and radio on print media.

description: Experimentally there exist many materials with first-order phase transitions at finite temperature that display quantum criticality. Classically a strain-energy density coupling is known to drive first-order transitions in compressible systems, and here we generalize this Larkin-Pikin mechanism to the quantum case. We show that if the T=0 system lies above its upper critical dimension, the line of first-order transitions can end in a quantum annealed critical point where zero-point fluctuations restore the underlying criticality of the order parameter.

description: Classical spin models with discrete or continuous degrees of freedom arise in many studies of complex physical systems. A wide class of hard real-life optimisation problems can be formulated as a minimisation of a spin Hamiltonian. Here we show how to simulate the discrete Ising and Potts models with or without external fields using the physical gain-dissipative platforms with continuous phases such as lasers and various non-equilibrium Bose-Einstein condensates. The underlying operational principle originates from a combination of resonant and non-resonant pumping. Our results lay grounds for the physical simulations of a broad range of Hamiltonians with complex interactions that can vary in time and space and with combined symmetries.

We study its performance at the example of the massive Gaussian model on the square and the simple cubic lattice, the $O(3)$-invariant non-linear $σ$-model and the $SU(3) \times SU(3)$ principle chiral model on the square lattice. In all these cases we find that critical slowing down is essentially eliminated.

description: L’introduction de la navigation à vapeur en Grèce est liée à la fondation de la Compagnie
 hellénique de navigation à vapeur (désormais la Compagnie) fondée en 1857. La
 Compagnie introduit deux importantes innovations dans le pays : le service passager
 et la construction et l’ingénierie navales modernes. Les communications maritimes
 à l’époque en Grèce étaient plutôt effectuées par des navires à voiles. Les vapeurs
 des compagnies étrangères, comme la Lloyd autrichienne, et les paquebots français
 desservaient uniquement les ports de Syros et du Pirée. En réalité, la Compagnie tient
 un rôle primordial dans l’unification et la consolidation de la présence de l’État dans
 un territoire national plutôt fragmenté, entre les îles des archipels des mers Égée et
 Ionienne et les côtes péninsulaires. Il faut également rappeler que la Grèce n’a pas
 développé de réseau de chemins de fer avant le dernier quart du xixe siècle, et avec le
 problème persistant du brigandage, les transports terrestres du pays sont restés sousdéveloppés

The hydrology of the Peruvian Amazon river and its sensitivity to climate change
Creators: name: Zulkafli, Zed Diyana
Publisher: name: Imperial College London
Year: 2014

description: This PhD thesis explores the utility of a land surface model (Joint UK Land-Environment Simulator, JULES) for large-scale hydrological modelling of the Peruvian Amazon - a humid tropical mountain basin where process understanding is poor and data are scarce. A sparse rain gauge network necessitates the use of large-scale data from satellite and global climate model reanalysis to complement ground observations, commanding a closer look at (1) the uncertainties (2) merging techniques to utilise multiple observations in the model forcing. A main outcome of the research is establishing the model’s sensitivity to precipitation error, and at the same time, demonstrating an increasing reliability of global remote sensing products as model forcing, specifically, with data from the Tropical Rainfall Measuring Mission Multisatellite Precipitation Analysis version 7 algorithm. Furthermore, satellite-rain gauge data assimilation techniques such as mean-bias correction, double smoothing residual blending, and Bayesian combination, are shown to reduce the mean errors in the satellite-based product. Secondly, with regional calibration and an offline runoff routing scheme, JULES is shown to be reasonably skillful at reproducing the observed streamflow dynamic and extremes. Representing the subgrid heterogeneity of soil moisture using the probability distributed model (PDM) was key to improving surface runoff generation. However, evapotranspirative fluxes in the lower basin remain poorly reproduced without an adequate floodplain system representation. Finally, under the Intergovernmental Panel for Climate Change’s RCP4.5 future climate scenario, which projects a warming and wetting up to the year 2035, the Peruvian Amazon basin is shown to respond nonlinearly to the increase in wet season precipitation with more than 40% increase in the peak flows compared to the baseline scenario. There is limited confidence in the projections due to climate projections uncertainty and the assumptions of model stationarity.

Development of pulsed diode pumped solid state lasers in the bounce amplifier geometry
Creators: name: Arbabzadah, Emma
Publisher: name: Imperial College London
Year: 2013

description: The work in this thesis focuses on the development of diode pumped solid state (DPSS) lasers, constructed using the bounce amplifier geometry. The bounce amplifier geometry employs a simple side pumping scheme using diode bars and stacks, leading to an efficient and compact system. The laser mode is total internally reflected at the pump surface, spatially averaging gain and thermal non-uniformities giving potential for excellent beam quality from these systems. In this thesis, novel pulsed laser sources based on the 1µm transition of the Nd3+ ion and the 3µm transition of the Er3+ ion are developed, and investigated both experimentally and numerically. An acousto-optically Q-switched Nd:YVO4 laser operating at 1064nm with ultra-high gain (~105) is developed, and using a novel pulse control technique is demonstrated to provide better performance and greater flexibility of the pulsing parameters. Pulsed lasers are useful for many applications, including industrially in laser micromachining and laser marking, where having greater control of laser parameters (e.g. pulse repetition rate, pulse duration and pulse energy) enhances the usefulness of the laser significantly. A problem associated with Q-switching of a high-gain laser system is the difficulty in obtaining clean, single pulse operation from very high (~1MHz) to low (~1kHz) repetition rates. The pulse control technique demonstrated for the first time in this work addresses this issue. The technique uses a secondary laser cavity to control the gain of a primary laser cavity. Prior to implementation of the technique, laser breakthrough occurred at low repetition rates due to the excessive gain and single pulsed operation was not possible below 150kHz. Using the pulse control technique, single pulsed operation was obtained from 800kHz down to 1kHz, with good beam quality across the range, as well as the ability for pulse energy control demonstrated. The development of 3μm laser sources, using Er3+ doped materials is presented. Lasers operating at 3µm are useful directly in applications in medicine and dentistry due to being near the peak of water absorption, as well as indirectly as pump sources for optical parametric generation for production of tuneable mid-IR radiation for spectroscopy, security and defence, and remote sensing applications. In this work, a comparison of the Er:YAG and Er:YSGG laser materials operating at the 3µm transition is undertaken showing superior performance from the less commonly used Er:YSGG material. Different cavity designs are subsequently investigated using the Er:YSGG laser material and an electro-optically Q-switched Er:YSGG laser at 3µm is developed. Numerical modelling of the erbium laser is presented providing greater understanding of laser operation in this complex laser system.

Resonant inverse Compton scattering above polar caps: Gap acceleration efficiency for young pulsars
Creators: name: Luo, Q.

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: It is shown that for moderately hot polar caps (with effective temperature of $\sim 10^6$ K), the efficiency of polar gap acceleration is lower compared to the case in which the polar caps are relatively cool and inverse Compton scattering plays no role in controlling the gap. For young pulsars with superstrong magnetic fields ($\geq10^9 T$) and hot polar caps (with temperature of $\ge 5\times10^6 K$), because of the energy loss of electrons or positrons due to resonant inverse Compton scattering in the vicinity of polar caps, pair cascades occur at distances further away from the polar cap, and in this case, we have a relatively high acceleration efficiency with ions carrying most of the particle luminosity.

title: Optimizing Resin Infiltration Treatment of Post-Orthodontic White Spot Lesions by Increasing Infiltrant Penetration Duration — In Vitro Study
Creators: name: Park, Hahnnah
Publisher: name: University of Nevada, Las Vegas
Year: 2023

description: Background: This study focuses on evaluating the effect of increasing duration allowed for  resin infiltrant penetration in improving the aesthetic outcome of resin infiltration treatment. Additional investigations into repeat treatment and long-term stability were also conducted. Artifically created white spot lesions were induced on one hundred extracted teeth made up of either incisors or canines. Teeth were divided into enamel and dentin groups depending on the extent of the lesion and then further subdivided into varying treatment protocol groups: 3-minute, 6-minute, and 9-minute penetration time. Teeth were thermocycled for one clinical year and then divided into a repeat treatment and no additional treatment group. Teeth were thermocycled for an additional clinical year. Spectrophotometric analysis was measured at all timepoints for all groups. Results: Mean ΔE values, for the enamel group, were slightly above or significantly below the critical value and, for the dentin group, were significantly above the critical value of 3.7. Mean ΔE values within the enamel and dein groups both demonstrated a downward trend with increasing time allowed for resin infiltrant penetration. A single treatment for a white spot lesion resulted in a significant difference compared to no treatment. No significant difference was found between groups that received a single or repeat treatment. There was significant difference in ΔE values for the D3 group following thermocycling after a single treatment. There was significant difference in ΔE values for all groups except the enamel group that received a single treatment following thermocycling after a single or repeat treatment.
Conclusions: Resin infiltration is an effective treatment modality to improve the appearance of white spot lesions. The aesthetic benefit of resin infiltration works best for shallow enamel lesions. Increasing the resin infiltrant penetration time to at least nine minutes is advised as the most optimized treatment protocol. Resin infiltration treatment is recommended only once per a tooth’s lifetime. At least 1-year color stability can be reasonably expected. An additional year of color stability can be expected following a single and optimized infiltration treatment of shallow lesions.

Engineered Biomolecules with Improved Functionalities for Bone Tissue Engineering
Creators: name: Tian, Pinyuan
Publisher: name: Imperial College London
Year: 2013

description: Biomolecules such as bone growth factors, extracellular matrix proteins, bioactive factor-derived peptides, and other mineralisation-promoting proteins are gaining increasing attention in bone tissue engineering due to the fact that they can play an important role in cell attachment, growth, differentiation, and migration, and therefore be used to enhance bone formation and develop bone substitutes. This study is focused on the development of engineered biomolecules with improved functionality, and their combination with supporting matrix materials for bone tissue engineering applications. Two types of biomolecules are studied: The first are short peptides derived from the growth factor bone morphogenetic protein 7 (BMP-7), which induces bone regeneration, and regulates bone formation. The second is an engineered recombinant metalloenzyme E. coli alkaline phosphatase (E. coli ALP), which hydrolyses organic phosphate and generates the inorganic phosphate required for the mineralisation of hard tissue. Titanium (Ti) implants and polycaprolactone (PCL) scaffolds were used to incorporate these engineered biomolecules to verify the improvement of their functionality and biological efficiency. Results indicate that the BMP-7-derived peptides have a limited function and are not promising candidates for bone tissue engineering applications; while the mutant E. coli ALP shows superior activity compare to the wild-type ALP (nearly 25 times) and bovine ALP (more than 9 times), and is shown to be a promising factor to enhance bone formation. The activity of E. coli ALP can be affected by many factors including NaCl, lyophilisation, histidine, and imidazole. When the ALP is combined with either a Ti implant or an ALP/PCL scaffold, it demonstrates outstanding mineral-promoting ability, making it a potential candidate for bone tissue engineering applications. In conclusion, this study demonstrates the potential of engineering biomolecules with improved functionalities for bone tissue engineering applications.
Towards the development of modulators of LRH-1 as potential anti-cancer therapeutic leads
Creators: name: Mueller, Melanie
Publisher: name: Imperial College London
Year: 2013

description: Breast cancer is the most common cancer in women worldwide and afflicts about 30 % of all women between 35 and 50 years. The majority of breast cancers are estrogen dependent. This means that they need estrogen for their development and growth. Estrogen dependent breast cancers can be treated with hormone therapy to block estrogen action and prevent cancer growth. Unfortunately, there are many side effects associated with this treatment and therefore, there is a great need for the development of new therapies for breast cancer. Liver receptor homologe-1 (LRH-1) is a nuclear receptor that recently came into focus for its implications in breast cancer development and growth. Targeting LRH-1 could present an alternative approach for the treatment of breast cancer. There are two potential sites to target nuclear receptors: the ligand binding pocket or the co-activator binding site. Both sites are known to be crucial for the transcriptional activity of nuclear receptors. This thesis gives an overview about breast cancer and the role of nuclear receptors in this disease. In particular, approaches to the regulation of nuclear receptors using small molecule antagonists are discussed both in terms of traditional “ligand binding pocket” inhibitors and the more recently explored “co-activator binding inhibitors”. Both approaches are explained generally and in the context of LRH-1. The work described here is divided into two parts: The first part describes the synthesis and evaluation of a library of benzimidazole-based potential antagonists of LRH-1. These molecules are expected to bind into the ligand binding pocket and act as traditional antagonists. The second part of this thesis explains the synthesis of an α-helix mimetic. A previous PhD student in the group developed a route for the synthesis of an α-helix mimetic. The mimetic targeted here was anticipated to bind competitively to the co-activator binding site of LRH-1 and prevents co-activators from binding and consequently blocks transcriptional activity.

description: Graphene/MoS2 heterostructures are formed by combining the nanosheets of graphene and monolayer MoS2. The electronic features of both constituent monolayers are rather well-preserved in the resultant heterostructure due to the weak van der Waals interaction between the layers. However, the proximity of MoS2 induces strong spin orbit coupling effect of strength ~1 meV in graphene, which is nearly three orders of magnitude larger than the intrinsic spin orbit coupling of pristine graphene. This opens a bandgap in graphene and further causes anticrossings of the spin-nondegenerate bands near the Dirac point. Lattice incommensurate graphene/MoS2 heterostructure exhibits interesting moire' patterns which have been observed in experiments. The electronic bandstructure of heterostructure is very sensitive to biaxial strain and interlayer twist. Although the Dirac cone of graphene remains intact and no charge-transfer between graphene and MoS2 layers occurs at ambient conditions, a strain-induced charge-transfer can be realized in graphene/MoS2 heterostructure. Application of a gate voltage reveals the occurrence of a topological phase transition in graphene/MoS2 heterostructure. In this chapter, we discuss the crystal structure, interlayer effects, electronic structure, spin states, and effects due to strain and substrate proximity on the electronic properties of graphene/MoS2 heterostructure. We further present an overview of the distinct topological quantum phases of graphene/MoS2 heterostructure and review the recent advancements in this field.

description: Detailed modeling of particle accelerators can benefit from parallelization on modern compute hardware such as GPUs and can often be distributed to large supercomputers. Providing production-quality implementations, the Beam, Plasma & Accelerator Simulation Toolkit (BLAST) provides multiple modern codes to cover the widely different time and length scales between conventional accelerator elements and advanced, plasma-based elements. The Exascale code WarpX provides electromagnetic and -static, t-based particle-in-cell routines, advanced algorithms and is highly scalable. For beam-dynamics, the s-based ImpactX code provides an efficient implementation for tracking relative to a nominal reference trajectory, including space charge. Integrated modeling of "hybrid" beamlines – integrating both detailed plasma models and large-scale transport at full detail – requires exchange between codes and is limited by the computational speed of the most-detailed element, usually the plasma element.

In this work, we present an alternative approach to coupling particle-in-cell models and codes beyond direct data exchange or reduced details for accelerator modeling. In particular, we investigate and demonstrate detailed data-driven modeling based on high-quality WarpX simulations that were used to train surrogate models for the beam transport code ImpactX. We describe new workflows, illuminate predictive quality, performance and applicability to central research topics in advanced accelerator research, such as staging of laser-wakefield accelerators.
Sharp Gradient Bounds for the Diffusion Semigroup
Creators: name: Nee, Colm
Publisher: name: Imperial College London
Year: 2011

description: Precise regularity estimates on diffusion semigroups are more than a mere theoretical curiosity. They play a fundamental role in deducing sharp error bounds for higher-order particle methods. In this thesis error bounds which are of consequence in iterated applications of Wiener space cubature (Lyons and Victoir [29]) and a related higher-order method by Kusuoka [21] are considered. Regularity properties for a wide range of diffusion semigroups are deduced. In particular, semigroups corresponding to solutions of stochastic differential equations (SDEs) with non-smooth and degenerate coefficients. Precise derivative bounds for these semigroups are derived as functions of time, and are obtained under a condition, known as the UFG condition, which is much weaker than Hormander's criterion for hypoellipticity. Moreover, very relaxed differentiability assumptions on the coefficients are imposed. Proofs of exact error bounds for the associated higher-order particle methods are deduced, where no such source already exists. In later chapters, a local version of the UFG condition - `the LFG condition' - is introduced and is used to obtain local gradient bounds and local smoothness properties of the semigroup. The condition's generality is demonstrated. In later chapters, it is shown that the V0 condition, proposed by Crisan and Ghazali [8], may be completely relaxed. Sobolev-type gradient bounds are established for the semigroup under very general differentiability assumptions of the vector fields. The problem of considering regularity properties for a semigroup which has been perturbed by a potential, and a Langrangian term are also considered. These prove important in the final chapter, in which we discuss existence and uniqueness of solutions to the Cauchy problem.

description: We study decoupling limits and S-dualities for noncommutative open string/ Yang-Mills theory in a gravity setup by considering an $SL(2,Z)$ invariant supergravity solution of the form ((F, D1), D3) bound state of type IIB string theory. This configuration can be regarded as D3-branes with both electric and magnetic fields turned on along one of the spatial directions of the brane and preserves half of the space-time supersymmetries of the string theory. Our study indicates that there exists a decoupling limit for which the resulting theory is an open string theory defined in a geometry with noncommutativity in both space-time and space-space directions. We study S-duality of this noncommutative open string (NCOS) and find that the same decoupling limit in the S-dual description gives rise to a space-space noncommutative Yang-Mills theory (NCYM). We also discuss independently the decoupling limit for NCYM in this D3 brane background. Here we find that S-duality of NCYM theory does not always give a NCOS theory. Instead, it can give an ordinary Yang-Mills with a singular metric and an infinitely large coupling. We also find that the open string coupling relation between the two S-duality related theories is modified such that S-duality of a strongly coupled open-string/Yang-Mills theory does not necessarily give a weakly coupled theory. The relevant gravity dual descriptions of NCOS/NCYM are also given.

description: Dynamical ensembles have been introduced to study constrained stochastic processes. In the microcanonical ensemble, the value of a dynamical observable is constrained to a given value. In the canonical ensemble a bias is introduced in the process to move the mean value of this observable. The equivalence between the two ensembles means that calculations in one or the other ensemble lead to the same result. In this paper, we study the physical conditions associated with ensemble equivalence and the consequences of non-equivalence. For continuous time Markov jump processes, we show that ergodicity guarantees ensemble equivalence. For non-ergodic systems or systems with emergent ergodicity breaking, we adapt a method developed for equilibrium ensembles to compute asymptotic probabilities while caring about the initial condition. We illustrate our results on the infinite range Ising model by characterizing the fluctuations of magnetization and activity. We discuss the emergence of non ergodicity by showing that the initial condition can only be forgotten after a time that scales exponentially with the number of spins.

description: In graphene superlattices, bulk topological currents can lead to long-range charge-neutral flow and non-local resistance near Dirac points. A ballistic version of these phenomena has never been explored. Here, we report transport properties of ballistic graphene superlattices. This allows us to study and exploit giant non-local resistances with a large valley Hall angle without a magnetic field. In the low-temperature regime, a crossover occurs toward a new state of matter, referred to as a quantum valley Hall state (qVHS), which is an analog of the quantum Hall state without a magnetic field. Furthermore, a non-local resistance plateau, implying rigidity of the qVHS, emerges as a function of magnetic field, and the collapse of this plateau is observed, which is considered as a manifestation of valley/pseudospin magnetism.

Greater Cairo Earthquake Loss Assessment and its Implications on the Egyptian Economy

description: This study develops a loss estimation model for assessing the seismic economic implications resulting from damage to Greater Cairo’s building stock, as well as natural gas and electricity lifelines. The model estimates both the direct and indirect economic losses resulting from seismic occurrences. The developed model is composed of three modules. The first of which is the ground shaking module which estimates ground-motion throughout Greater Cairo. This is done through investigating the seismicity of Egypt and its surroundings, in order to develop recurrence relationships. Furthermore, through the use of geological and geotechnical data, seismic geological classification is conducted. This investigation is used along with three attenuation relationships to estimate ground-motion throughout Greater Cairo. The second module evaluates the damage to the building stock as well as natural gas and electricity lifelines. This is done through developing a building inventory database, and classifying structures in this database according to various classes. Moreover, data regarding components in the natural gas and electricity networks is collected, and through the use of minimum cut sets the networks’ behaviour is assessed. Finally, through the use of fragility curves the vulnerability of structures and components is evaluated. The final module estimates the direct economic losses associated with repairing damaged components. Furthermore, the indirect costs associated with business interruption resulting from disruption to elements in the built environment are also estimated. This study will pave the way for developing countries to recognize the impacts of earthquakes on their economies. Moreover, it will be useful for countries that exhibit a centralized economy that is dependant on major cities. Furthermore it provides a step forward in earthquake loss estimation to model multiple lifelines, rather than past research which modelled each lifeline separately.

description: We present Keck spectropolarimetry of the highly polarized radio-loud quasar 3CR 68.1 (z=1.228, V=19). The polarization increases from 5 in the red (4000 A rest-frame) to >10% in the blue (1900 A rest-frame). The broad emission lines are polarized the same as the continuum, which shows that 3CR 68.1 is not a blazar as it has sometimes been regarded in the past. We also present measurements of the emission lines and a strong, blueshifted, associated absorption line system, as well as a detection at the emission-line redshift of Ca II K absorption, presumably from stars in the host galaxy. 3CR 68.1 belongs to an observationally rare class of highly polarized quasars that are neither blazars nor partially obscured radio-quiet QSOs. Taking into account 3CR 68.1's other unusual properties, such as its extremely red spectral energy distribution and its extreme lobe dominance, we explain our spectropolarimetric results in terms of unified models. We argue that we have a dusty, highly inclined view of 3CR 68.1, with reddened scattered (polarized) quasar light diluted by even more dust-reddened quasar light reaching us directly from the nucleus.

Recovery dynamics of the Caribbean long-spined sea urchin, Diadema antillarum
Creators: name: Rogers, Alice
Publisher: name: Imperial College London

description: The sea urchin Diadema antillarum is a keystone herbivore in the Caribbean and its functional extinction due to an epidemic in 1983 had a marked effect on coral reef health. Recovery of D. antillarum has been associated with improvements in reef health but has been unexpectedly slow and patchy with many populations persisting at low abundance on the reefs. This thesis investigates possible reasons for low and variable recovery of D. antillarum on the reef using combined techniques of population dynamic modelling, meta-analysis and field experimentation. Population dynamic modelling was used to explore the implications of alternative process hypotheses for recovery dynamics. Depensatory density dependence (Allee effects) or cultivation effects are predicted to lead to complex dynamics characterized by switching between alternative, high and low abundance states. Density independent variation in vital rates, e.g. due to environmental change, are predicted to affect recovery abundance and rates without leading to complex dynamics. Time series data explored through meta-analysis, and local recovery patterns examined in Curacao, exhibit recovery dynamics and spatial distributions which indicate that variation in density independent factors, rather than depensatory density dependent processes are the key drivers of population dynamics. Recovering populations and patches of high D. antillarum abundance are both associated with locations which exhibit high resource availability, high macroalgal abundance, few herbivorous fish competitors, reduced predation risk and local larval retention. Specifically, I find evidence to suggest that rates of recovery are determined by resource availability and population sizes are controlled by predation pressure and larval retention. Interestingly, the environmental characteristics which appear favourable to D. antillarum are also characteristics which tend to result from high levels of human threat. My results demonstrate that D. antillarum populations favour specific habitat characteristics which occur in a variety of habitat types and indicate that coral reefs, upon which most attention has been focused, actually represent relatively poor habitat for the species. In light of this, I predict that the widespread reappearance of D. antillarum on coral reefs will only occur once population densities in preferred, sheltered, shallow, nutrient enriched, often humanimpacted habitats become high enough to depress habitat quality in these locations, such that forereefs become suitable as alternative habitats.
The Lx-T Relation and Temperature Function for Nearby Clusters Revisited

description: The X-ray luminosity-temperature relation for nearby T=3.5-10 keV clusters is rederived using new ASCA temperatures and ROSAT luminosities. Both quantities are derived by directly excluding the cooling flow regions. This correction results in a greatly reduced scatter in the Lx-T relation; cooling flow clusters are similar to others outside the small cooling flow regions. For a fit of the form L_bol ~ T^alpha, we obtain alpha=2.64+-0.27 (90%) and a residual rms scatter in log L_bol of 0.10. The derived relation can be directly compared to theoretical predictions that do not include radiative cooling. It also provides an accurate reference point for future evolution searches and comparison to cooler clusters. The new temperatures together with a newly selected cluster sample are used to update the temperature function at z~0.05. The resulting function is generally higher and flatter than the previous estimates by Edge et al (1990) and Henry & Arnaud (1991, corrected). For a qualitative estimate of constraints that the new data place on the density fluctuation spectrum, we apply the Press-Schechter formalism for Omega=1 and 0.3. For Omega=1, assuming cluster isothermality, the temperature function implies sigma_8=0.55+-0.03, while taking into account the observed cluster temperature profiles, sigma_8=0.51+-0.03, consistent with the previously derived range. The dependence of sigma_8 on Omega differs from earlier findings, because of our treatment of n as a free parameter. We find n=-(2.0-2.3)+-0.3, somewhat steeper than derived from the earlier temperature function data, in agreement with the local slope of the galaxy fluctuation spectrum from the APM survey, and significantly steeper than the standard CDM prediction.
